The water discharge unit 20 has the function of discharging water purified by the purification unit 40 from the water outlet 13 of the faucet 12 in the circulation unit 6.

The water discharge unit 20 mainly comprises a water discharge pump 21, a UV sterilization section 22, and an infrared sensor 23.

The discharge pump 21 is disposed downstream of the water storage tank 46 provided in the purification unit 40. The discharge pump 21 is operated under the control of the control unit 60, and sends out water stored in the water storage tank 46 to the UV sterilization unit 22.
Specifically, the control unit 60 operates the discharge pump 21 in response to detection of an object by the infrared sensor 23. For example, the control unit 60 operates the discharge pump 21 while an object is detected by the infrared sensor 23. The control unit 60 stops the discharge pump 21 when an object is no longer detected by the infrared sensor 23.

The UV sterilization unit 22 is disposed between the discharge pump 21 and the faucet 12. The UV sterilization unit 22 irradiates the water discharged from the discharge pump 21 with ultraviolet light to sterilize the water. The water that has passed through the UV sterilization unit 22 is discharged from the water outlet 13 of the faucet 12 as cleaning water.
An air vent 72 is provided between the discharge pump 21 and the UV sterilization section 22 to remove air from the water discharged from the discharge pump 21.

The drainage unit 30 has the function of draining the washing water discharged from the faucet 12 toward the hand washing basin 11 in the circulation unit 6.

The drainage unit 30 mainly includes a trap 35 , a capacitance sensor 31 , and a drainage pump 32 .
Trap 35 is provided in the pipe that drains the wash water from hand-washing basin 11. Trap 35 prevents, for example, bad odors or gases from flowing back, and also prevents foreign matter that has entered through drain outlet 17 from reaching purification unit 40.

The drainage pump 32 is disposed after the trap 35. The drainage pump 32 is operated under the control of the control unit 60, and sends the water that has passed through the trap 35 to a pre-treatment filter 41 provided in the purification unit 40.
Specifically, the control unit 60 operates the drainage pump 32 in response to the detection of water by the capacitance sensor 31. For example, the control unit 60 operates the drainage pump 32 while water is detected by the capacitance sensor 31. The control unit 60 stops the drainage pump 32 when water is no longer detected by the capacitance sensor 31.

The capacitance sensor 31 is disposed between the trap 35 and the drain pump 32. The capacitance sensor 31 detects the capacitance in the drain pipe. This allows the water drained from the hand washing basin 11 and supplied through the trap 35 to be detected. Note that the sensor for detecting the water supply is not limited to the capacitance sensor 31. The water supply may be detected by referring to other sensing results.

An air vent 70 is provided between the drainage pump 32 and the purification unit 40 to remove air from the water discharged from the drainage pump 32.

The purification unit 40 has the function of purifying the water supplied from the drainage unit 30 in the circulation unit 6.

The purification unit 40 mainly comprises a pre-treatment filter 41, a reverse osmosis membrane 42, a post-treatment filter 43, an intermediate tank 44 (first tank), a drainage tank 45 (second tank), a water storage tank 46 (third tank), and a membrane filtration pump 47.

In this embodiment, an activated carbon filter is used as the pretreatment filter 41, but is not limited thereto. For example, at least one of a thread-wound filter, a sediment filter, an MF (microfiltration membrane), an UF (ultrafiltration membrane), an NF (nanofiltration membrane), a ceramic filter, an ion exchange filter, and a metal membrane may be selected. In this embodiment, the pretreatment filter 41 is disposed outside the housing 2 as a part of the external module 7.
A pressure sensor 33 is disposed upstream of the pre-treatment filter 41. The pressure sensor 33 detects the pressure of the water supplied to the pre-treatment filter 41.

A flow rate sensor 34 is disposed downstream of the pretreatment filter 41. The flow rate sensor 34 detects the flow rate of the water that has been pretreated by the pretreatment filter 41.

The intermediate tank 44 (first tank) is disposed after the pre-treatment filter 41 .
The intermediate tank 44 is a tank for storing the supplied water. Water that has been pretreated by the pretreatment filter 41 and concentrated water that has been separated by the reverse osmosis membrane 42 and passed through the two-way electromagnetic valve 74 flow into the intermediate tank 44. The intermediate tank 44 stores the water that flows in from the two systems.
A water level sensor is disposed in the intermediate tank 44. The water level sensor detects the level of the water stored in the intermediate tank 44.

The membrane filtration pump 47 is disposed between the intermediate tank 44 and the reverse osmosis membrane 42 .
The membrane filtration pump 47 is operated under the control of the control unit 60, and increases the pressure of the water stored in the intermediate tank 44 to a preset pressure, and supplies the water to the reverse osmosis membrane 42. Note that the preset pressure is, for example, a pressure that is at least higher than the osmotic pressure.

The reverse osmosis membrane 42 separates the water, which is pressurized and supplied by the membrane filtration pump 47, into permeated water from which dissolved components have been removed and concentrated water from which the dissolved components have been concentrated. The reverse osmosis membrane 42 is realized by, for example, a spiral reverse osmosis membrane.
The concentrated water separated by the reverse osmosis membrane 42 is discharged to the intermediate tank 44 via the two-way solenoid valve 74 and the pressure regulating valve 73 when the two-way solenoid valve 74 is open. The concentrated water separated by the reverse osmosis membrane 42 is discharged to the drainage tank 45 via the two-way solenoid valve 75 when the two-way solenoid valve 75 is open. The permeated water separated by the reverse osmosis membrane 42 is discharged to the post-treatment filter 43.

The two-way solenoid valve 74 is a device that opens and closes the valve using the electromagnetic force of an electromagnetic coil. The two-way solenoid valve 74 is normally open and is structured to close the valve in response to a signal from the control unit 60.

The pressure regulating valve 73 adjusts the flow rate or pressure of the concentrated water supplied to the intermediate tank 44.

The two-way solenoid valve 75 is a device that opens and closes the valve using the electromagnetic force of an electromagnetic coil. The two-way solenoid valve 75 is normally closed and opens in response to a signal from the control unit 60.

An air vent 71 is provided between the membrane filtration pump 47 and the sensor unit 61 to remove air from the water discharged from the membrane filtration pump 47.

The post-treatment filter 43 is disposed downstream of the reverse osmosis membrane 42. The post-treatment filter 43 performs post-treatment on the permeated water discharged from the reverse osmosis membrane 42 to remove impurities that could not be completely filtered by the reverse osmosis membrane.
In this embodiment, an activated carbon filter is used as the post-treatment filter 43, but is not limited thereto. For example, at least one of a thread-wound filter, a sediment filter, an MF (microfiltration membrane), an UF (ultrafiltration membrane), an NF (nanofiltration membrane), a ceramic filter, an ion exchange filter, and a metal membrane may be selected. In this embodiment, the post-treatment filter 43 is disposed outside the housing 2 as a part of the external module 7.

A sensor unit 62 is disposed in front of the post-processing filter 43. In the illustrated example, the sensor unit 62 has a pressure sensor, a flow rate sensor, and an EC/temperature sensor.

The pressure sensor detects the pressure of the permeated water supplied to the post-treatment filter 43.

The flow sensor detects the flow rate of the permeated water supplied to the post-treatment filter 43.

The EC/temperature sensor detects the electrical conductivity and temperature of the permeate supplied to the post-treatment filter 43 .
In addition to the above sensors, the sensor unit 62 may have a sensor that senses at least one of (1) to (7) shown in the sensor unit 61.

The UV sterilization device 80 is formed with an insertion port 81 that opens upward. A user inserts a smartphone through the insertion port 81. Here, the UV sterilization device 80 may open in another direction, such as to the side, in addition to opening upward as shown in the figure.

When a smartphone is inserted through insertion port 81 and placed on a base (not shown) inside UV sterilization device 80 , UV sterilization device 80 lowers the base and pulls the smartphone into the inside of UV sterilization device 80 .
A lid (not shown) is closed when the base is lowered to a predetermined position inside the UV sterilization device 80. When the lid is closed, the UV sterilization device 80 turns on the ultraviolet light source (lamp).

At this time, the light source may irradiate ultraviolet light in a directional manner toward a specific area of the smartphone that is likely to be particularly dirty, such as the area near the home button or the center area of the display. The specific location may be set statistically based on typical examples of smartphone operation.

The specified position may also be set based on the operation log of the inserted smartphone. In this way, by concentrating the ultraviolet light on particularly dirty areas, it is possible to shorten the time required for sterilization.

For example, the hand-washing device 1 may communicate with a user's personal item (e.g., a device with communication capabilities such as a smartphone) to obtain information about the personal item or information about the user.

Specifically, (1) if the hand-washing device 1 is provided with a communication unit that communicates with a smartphone or the like via short-range wireless communication (NFC (Near Field Communication) using an IC chip, high-speed wireless communication standard, etc.), the user first places the smartphone in a predetermined position on the hand-washing device 1 before sterilizing the smartphone with the UV sterilization device 80 on the hand-washing device 1. This causes the smartphone to transmit predetermined information to the hand-washing device 1.

The predetermined information here includes information such as the smartphone model information, information on the attributes of the smartphone user (for example, an employee code if the user is an employee, etc., an age group of the user if the user is a general consumer, membership number information if the user is registered for a service provided by a store, etc., information used when processing payments (user identification information of the payment application, credit card information, etc.), and an operation log of the user's smartphone operations (coordinates of contact with the touch screen, operation history of the application, etc.). In this way, the user may be able to set the range in which information is provided from the smartphone to the hand-washing device 1), etc., and the like may be read by the hand-washing device 1.

Also, (2) the hand-washing device 1 is managed by an external server or the like and is capable of communicating with the external server or the like. A two-dimensional code such as a QR code (registered trademark) containing information identifying the hand-washing device 1 (e.g., a URL containing identification information for the hand-washing device 1) is attached to the hand-washing device 1 or displayed on the screen. The two-dimensional code is read by the user's smartphone, and the smartphone communicates information including the identification information for the hand-washing device 1 with the external server or the like, so that the external server or the like can transmit information such as the model of the smartphone to the hand-washing device 1.

(3) In addition, if the hand-washing device 1 has a reading unit (such as an optical scanner) that reads a two-dimensional code (including information about the smartphone model) displayed on a smartphone or the like, the user may display the two-dimensional code on the smartphone screen and have the hand-washing device 1 read it.

As described above, an example in which the hand washing device 1 and the smartphone communicate wirelessly has been described.
(4) The hand washing device 1 may be directly connected to a smartphone or the like.
The hand-washing device 1 may determine the range of the smartphone to be irradiated with ultraviolet light by the UV sterilization device 80 based on the information on the model of the smartphone. For example, the position of the home button on the smartphone (the size of the smartphone and the position of the home button are determined depending on the model of the smartphone), the area corresponding to the bottom to the center of the screen when the user operates the smartphone in a vertical holding position (the area where the user's fingers frequently touch when the user operates the smartphone in a vertical holding position), and the area corresponding to the left and right sides of the screen when the user operates the smartphone in a horizontal holding position may be preferentially irradiated with ultraviolet light compared to other areas. For example, when the time for sterilization by the UV sterilization device 80 (time for ultraviolet light irradiation) is set to a certain time in conjunction with the time for hand-washing, the hand-washing device 1 may determine the range to be preferentially irradiated by the UV sterilization device 80 within the certain time as described above.

The hand-washing device 1 may also determine the hand-washing time and the sterilization time by the UV sterilization device 80 based on information on the attributes of the user. For example, when the hand-washing device 1 is used by an employee or other related party of the facility where the hand-washing device 1 is installed, the hand-washing device 1 may read the information of the related party and set the hand-washing time and the sterilization time by the UV sterilization device 80 according to the related party's attributes. Some users may need to wash their hands and sterilize their belongings, especially in jobs where they are expected to have a lot of contact with people. In this way, the hand-washing device 1 transmits a log of the time when the employee washed their hands and sterilized their belongings with the hand-washing device 1 to an external server or the like. If the external server or the like manages entry and exit to the facility, entry and exit may be controlled based on the history of the user washing their hands with the hand-washing device 1. For example, there may be some rooms where the user can enter even if they have not washed their hands with the hand-washing device 1, and there may be some rooms where the user cannot enter if they have not washed their hands. In this way, the facility manager can regulate entry and exit based on the history of the user washing their hands with the hand-washing device 1.

The UV sterilization device 80 turns on the UV light for a preset period of time and then turns off the UV light. The preset period of time corresponds to, for example, a generally recommended time for hand-washing.
When the UV light is turned off, the UV sterilization device 80 opens the cover and raises the base to a predetermined position. The predetermined position refers to a position where a part of the smartphone protrudes from the insertion port 81 so as to be touchable by the user.
This allows the user to insert and remove the smartphone without touching the UV sterilization device 80 while sterilizing the smartphone.
The hand-washing device 1 may be configured to discharge water from the water outlet 13 in response to a portable item being placed on the UV sterilization device 80. This can prevent the user from forgetting to sterilize the portable item with the UV sterilization device 80.

A sterilization indicator 16 (second indicator) is disposed on the outside of the hand washing basin 11 on the top surface of the housing 2. The sterilization indicator 16 displays the progress of the sterilization process of the portable items by the UV sterilization device 80.

The sterilization indicator 16 is arranged on a portion of the top plate 10 that is located between the hand washing basin 11 and the UV sterilization device 80 when viewed from above.
The sterilization indicator 16 is, for example, a circular indicator lamp when viewed from above. The sterilization indicator 16 is configured with an LED light. The lighting mode and control process of the sterilization indicator 16 will be described later.

<Control process of hand washing device 1>
Next, a description will be given of the control process of the hand-washing device 1. FIG 6 is an explanatory diagram showing the control process of the hand-washing device 1.

(Water discharge process of the water discharge unit 20)
First, the water discharge process from the faucet 12 in the water discharge unit 20 will be described.
As shown in FIG. 6, the control unit 60 turns off the water discharge pump 21 (step S11).

The control unit 60 determines whether an object has been detected by the infrared sensor 23 (step S12). When using the hand-washing device 1, the user places their hand in the hand-washing basin 11 and causes the infrared sensor 23 located at the tip of the faucet 12 to detect their fingers.

In response to detection of a finger by the infrared sensor 23 (YES in step S12), the control unit 60 operates the water discharge pump 21 (step S13).
The discharge pump 21 passes the water stored in the water storage tank 46 through the UV sterilization unit 22. The UV sterilization unit 22 sterilizes the water discharged from the discharge pump 21 by irradiating the water with ultraviolet rays. The water that has passed through the UV sterilization unit 22 is discharged from the water outlet 13 of the faucet 12 as cleaning water.
On the other hand, if no finger is detected by the infrared sensor 23 in step S12 (NO in step S12), the water discharge pump 21 does not operate (step S11).

The control unit 60 determines whether or not an object has been detected by the infrared sensor 23 (step S14). When the user wants to end the hand-washing device 1 or to cause the dispenser 14 to dispense the medicine, the user moves his or her fingers away from the infrared sensor 23 disposed at the tip of the faucet 12.
The control unit 60 stops the water discharge pump 21 (step S11) in response to the infrared sensor 23 not detecting a finger (NO in step S14).

On the other hand, in step S14, if the infrared sensor 23 does not detect a finger (YES in step S14), the control unit 60 continues to operate the water discharge pump 21 (step S13).
The water discharge unit 20 repeats these processes to discharge flush water from the faucet 12.
The control unit 60 may stop discharging water when a hand or finger has been detected for a certain period of time by measuring the time that the infrared sensor 23 detects the hand or finger. Furthermore, the control unit 60 may stop discharging water in response to the completion of sterilization by the UV sterilization device 80 while discharging water.

(Drainage treatment of drainage unit 30)
Next, the drainage treatment in the drainage unit 30 will be described.
As shown in FIG. 6, when there is no drainage from the hand-washing basin 11, the drainage pump 32 is stopped (step S21).
Then, when the wash water discharged from the faucet 12 toward the hand-washing basin 11 is drained from the drain outlet 17 of the hand-washing basin 11, the capacitance sensor 31 detects the drainage (step S22).

When the capacitance sensor 31 detects drainage (YES in step S22), the control unit 60 operates the drainage pump 32 (step S23).
On the other hand, if the capacitance sensor 31 does not detect drainage (NO in step S22), the control unit 60 does not operate the drainage pump 32 (step S21).

In step S23, the drainage pump 32 sends out drainage to the pre-treatment filter 41. The water that has been pre-treated in the pre-treatment filter 41 flows into the intermediate tank 44 and is stored there. The pressure sensor 33 detects the pressure of the water sent to the pre-treatment filter 41. The flow rate sensor 34 detects the flow rate of the water that has been pre-treated in the pre-treatment filter 41.

After step S23, when the capacitance sensor 31 detects that no more wastewater is flowing in from the drain outlet 17 (NO in step S24), the control unit 60 stops the drain pump 32 (step S21).
On the other hand, in step S24, if the capacitance sensor 31 detects that wastewater continues to flow in from the drain outlet 17 (YES in step S24), the control unit 60 continues to operate the drain pump 32 (step S23).

The drainage unit 30 repeats these processes and supplies the water discharged from the drain outlet 17 of the hand-washing basin 11 to the pre-treatment filter 41.

(Control process of purification unit 40)
Next, the cleaning process in the purification unit 40 will be described.
As shown in FIG. 6, initially, the membrane filtration pump 47 is stopped (step S31).

The control unit 60 determines whether the drain pump 32 is operating (step S32).
When the drainage pump 32 is operating (YES in step S32), the control unit 60 operates the membrane filtration pump 47 (step S33). As a result, the water stored in the intermediate tank 44 is supplied to the reverse osmosis membrane 42 at high pressure by the membrane filtration pump 47.

On the other hand, if the drainage pump 32 is not operating (NO in step S32), the control unit 60 keeps the membrane filtration pump 47 not operating (step S31).

In step S33, the water supplied to the reverse osmosis membrane 42 is separated into concentrated water and permeated water by the reverse osmosis membrane 42. The permeated water is supplied to the post-treatment filter 43.
The concentrated water flows into the intermediate tank 44 through the two-way electromagnetic valve 74. Since the two-way electromagnetic valve 75 is closed, the concentrated water does not flow into the drain tank 45.

In the post-treatment filter 43, post-treatment is performed on the permeated water. Then, hypochlorous acid water is added to the permeated water that has been post-treated in the post-treatment filter 43, and the permeated water flows into the water storage tank 46.

After step S33, the control unit 60 determines whether the electrical conductivity detected by the EC/temperature sensor of the sensor unit 61 arranged upstream of the reverse osmosis membrane 42 is less than a predetermined value (step S34).
If the electrical conductivity detected by the EC/temperature sensor is less than the predetermined value (YES in S34), the control unit 60 determines whether the drain pump 32 is operating (step S35). If the drain pump 32 is operating (YES in step S35), the control unit 60 continues to operate the membrane filtration pump 47 (step S33).

On the other hand, in step S34, if the electrical conductivity detected by the EC/temperature sensor is equal to or greater than the predetermined value (NO in step S34), the control unit 60 turns on the two-way solenoid valve 74 and the two-way solenoid valve 75 (step S36). This closes the two-way solenoid valve 74 and opens the two-way solenoid valve 75.

When the two-way solenoid valve 74 is closed and the two-way solenoid valve 75 is opened, the concentrated water separated by the reverse osmosis membrane 42 flows into the drain tank 45 via the two-way solenoid valve 75. That is, the control unit 60 determines the amount of impurities in the concentrated water based on the change in electrical conductivity detected by the EC/temperature sensor. Concentrated water determined to have a large amount of impurities is discharged into the drain tank 45.

When the water level of the concentrated water stored in the drainage tank 45 reaches a predetermined value, an alert is issued, for example, to the manager of the hand-washing device 1. When the manager confirms the alert, he or she discards the water stored in the drainage tank 45.

The control unit 60 continues the process of step S36 for a predetermined time (step S37), and after the predetermined time has elapsed, turns off the two-way solenoid valves 74 and 75. As a result, the two-way solenoid valve 74 is opened and the two-way solenoid valve 75 is closed.
In this manner, the two-way solenoid valve 74 is opened and the two-way solenoid valve 75 is closed, so that the concentrated water separated by the reverse osmosis membrane 42 flows into the intermediate tank 44 via the two-way solenoid valve 74. Then, the control unit 60 stops the membrane filtration pump 47 (step S31).

If the drainage pump 32 is stopped in step S35 (NO in step S35), the control unit 60 stops the membrane filtration pump 47 (step S31) after a predetermined time has elapsed (step S38).

The purification unit 40 repeats these processes to purify the water drained by the drainage unit 30 and store it in the water storage tank 46.

(Process of Removing Water from Water Storage Tank 46)
Next, the process of removing the water from the water tank 46 will be described.
The hand-washing device 1 is portable, and the installation location can be changed as needed. When the hand-washing device 1 is to be transported, the water in the water storage tank 46 is removed to reduce the weight of the hand-washing device 1 in order to facilitate the transport operation.
In addition, regardless of whether or not transportation work is performed, work to remove the water from the water storage tank 46 is also performed when the hand-washing device 1 is stored for a long period of time, when the hand-washing device 1 is closed, etc.

The hand-washing device 1 can be switched between a first state for a user to wash his/her hands and a second state for removing water from the water storage tank 46. The first state represents a state in which the water outlet 13 of the faucet 12 is located above the hand-washing basin 11.
On the other hand, the second state represents a state in which the water outlet 13 of the faucet 12 is located above and outside the housing 2.
When removing the water from the water storage tank 46, the water discharge unit 20 is operated in the second state.

Specifically, when the water outlet 13 of the faucet 12 is located above and outside the housing 2, the administrator causes the infrared sensor 23 of the faucet 12 to detect fingers. When the infrared sensor 23 detects fingers, the control unit 60 operates the water discharge pump 21 of the water discharge unit 20, causing water to be discharged from the faucet 12.

The administrator maintains the detection of the hand and drains all of the wash water in the water tank 46 from the water outlet 13, thereby emptying the water tank 46.
In the second state, the control unit 60 may directly operate the discharge pump 21 without using the infrared sensor 23 of the faucet 12, thereby discharging all of the flush water in the water storage tank 46 from the discharge outlet 13.

The first state and the second state may be switched manually or automatically. For example, in the first state, the manager manually moves the water outlet 13 of the faucet 12 located above the hand-washing basin 11 to an upper position outside the housing 2. When the hand-washing device 1 is in the first state, the hand-washing device 1 may transition from the first state to the second state in response to the water outlet 13 of the faucet 12 being moved to an upper position outside the housing 2.
Also, for example, the administrator inputs a predetermined command in the first state, whereupon the water outlet 13 of the faucet 12 located above the hand-washing basin 11 automatically moves to an upper position outside the housing 2.

The output of notifications such as errors may be changed depending on whether the hand-washing device 1 is in the first state or the second state. For example, when the hand-washing device 1 is in the first state, if the water tank 46 or the like does not have a certain amount of water remaining so that the user can wash their hands from the water outlet 13 of the faucet 12, an error may be notified by causing the hand-washing indicator 15 to emit a predetermined light, while when the hand-washing device 1 is in the second state, no error may be notified even if the remaining amount in the water tank 46 or the like falls below a certain amount.

The manner in which water is discharged from the water outlet 13 of the faucet 12 may be changed depending on whether the hand-washing device 1 is in the first state or the second state. For example, when the hand-washing device 1 is in the first state, if a certain time has passed since water was discharged from the water outlet 13, the water discharge may be stopped even if the infrared sensor 23 detects the user's fingers (the time for discharging water for hand-washing may be within a certain period of time), but when the hand-washing device 1 is in the second state, the water discharge from the water outlet 13 may not be stopped regardless of the passage of time.

<Display Mode and Control Process of Hand-Washing Indicator 15>
Next, a description will be given of the display mode and control process of the hand-washing indicator 15. Fig. 7 is a diagram for explaining the display mode of the hand-washing indicator 15. Fig. 8 is an explanatory diagram showing the control process of the hand-washing indicator 15.

As shown in FIG. 8, when the hand-washing device 1 is not in use, the LED light constituting the hand-washing indicator 15 is turned off (step S41).
Next, control unit 60 determines whether dispenser 14 has been operated (step S42). When a user who uses hand-washing device 1 holds his/her hand under dispenser 14, infrared sensor 52 of dispenser 14 detects the hand. When infrared sensor 52 detects the hand, control unit 60 operates chemical pump 51 to eject chemical from dispenser 14.
When the dispenser 14 is operating (YES in step S42), the control unit 60 turns on the hand-washing indicator 15 (steps S43 to S44).

Specifically, the control unit 60 turns on the 30 LED lights that make up the hand-washing indicator 15 in clockwise order, starting from the LED light located near the base of the faucet 12 when viewed from above, as shown in FIG. 7A. At this time, the control unit 60 turns on all the LED lights in, for example, about 1 to 2 seconds.

Then, as shown in Fig. 7B, when all the LED lights are turned on (step S44), the control unit 60 maintains the turned-on state for a predetermined time thereafter. After the predetermined time has elapsed, the control unit 60 turns off the LED lights in order, starting with the LED light located near the base of the faucet 12, in a clockwise direction, as shown in Fig. 7C (step S45).
At this time, the control unit 60 controls so that all the LED lights are turned off in about 30 to 40 seconds, for example.

The hand-washing device 1 may detect the user's fingers with the infrared sensor 23 and sequentially turn off the hand-washing indicators 15 over time as described above in response to the discharge of water from the water outlet 13. This allows the hand-washing indicators 15 to change their illuminated state as water is discharged from the water outlet 13, allowing the user to recognize the time from the discharge of water to the completion of hand-washing.
In addition, when the hand-washing device 1 does not detect a user's hands or fingers using the infrared sensor 23, it may notify users around the hand-washing device 1 to encourage them to wash their hands by, for example, lighting up the hand-washing indicator 15 in a predetermined manner (such as by emitting light in a predetermined color).

Then, as shown in FIG. 7D, when all the LED lights are turned off (step S45), the process returns to the initial state (step S41).
The time taken for the hand-washing indicators 15 to turn on and off in sequence is set to a generally recommended hand-washing time, for example, about 40 seconds, so that the hand-washing device 1 can present the user with a rough guide for the hand-washing time that can be expected to produce a sufficient washing effect.

<Display mode of sterilization indicator 16 and control process>
Next, a description will be given of the display mode and control process of the hand-washing indicator 15. Fig. 9 is a diagram for explaining the display mode of the hand-washing indicator 15. Fig. 10 is an explanatory diagram showing the control process of the hand-washing indicator 15.

As shown in FIG. 10, when the UV sterilization device 80 is not in use, the LED light constituting the sterilization indicator 16 is turned off (step S51). When no personal item is inserted into the UV sterilization device 80, the sterilization indicator 16 remains turned off (NO in step S52 in FIG. 10).

As shown in Fig. 9A, when a portable item (smartphone) is inserted into the insertion port 81 of the UV sterilization device 80 and the portable item is pulled into the UV sterilization device 80 (YES in step S52), the control unit 60 causes the LED light constituting the sterilization indicator 16 to flash (step S53) as shown in Fig. 9B. At this time, the control unit 60 causes the LED light to flash in red, for example.

The control unit 60 shortens the cycle at which the LED light blinks as time passes since the LED light started blinking (step S54). The sterilization process in the UV sterilization device 80 corresponds to the control of the sterilization indicator 16. In other words, the control unit 60 speeds up the blinking as the sterilization process in the UV sterilization device 80 progresses.

When the sterilization process in the UV sterilization device 80 is completed, the control unit 60 turns on the LED light in a color different from the previous blinking color (step S55), as shown in Fig. 9D. The LED light turns on in green, for example. This lighting indicates the end of the sterilization process.
When the sterilization process is completed and the UV light is turned off, the UV sterilization device 80 opens the cover and raises the user's carried items to a position where they can be removed.

Then, when the carried item is removed from the insertion slot 81 (YES in step S56), the control unit 60 turns off the LED light (step S51).
On the other hand, if the user does not remove the carry-on item from the insertion port 81 (NO in step S56), the control unit 60 keeps the LED light on (step S55). By keeping the LED light on in this manner, it is possible to prevent the user from forgetting to remove the carry-on item from the insertion port 81.

The processing time of the sterilization process in the UV sterilization device 80 may be the same as or equivalent to the lighting time of the hand-washing indicator 15. In this way, the time of the user's hand-washing and the time of the sterilization process by the UV sterilization device 80 can be associated with each other.
This makes it possible to avoid a situation in which a user who has finished washing their hands has to wait an extra amount of time for the UV sterilization process to finish.

As described above, according to the hand washing device 1 of this embodiment, in the hand washing device 1 equipped with a circulation unit 6 that purifies wastewater from the hand washing basin 11 and circulates it as cleaning water, the water outlet 13 of the faucet 12 can be positioned above the hand washing basin 11 or above outside the housing 2.
Therefore, by positioning the water outlet 13 of the faucet 12 above and outside the housing 2 and operating the pump of the circulation unit 6, it is possible to discharge the cleaning water outside the hand-washing device 1.

In other words, for example, there is no need to attach a hose to the tip of the faucet 12 or to remove the water tank 46, which has a certain weight, from inside the housing 2. This makes it possible to easily remove the cleaning water from inside the water tank 46 and reduce the difficulty of moving it.

In addition, since the housing 2 is cylindrical, the hand washing device 1 can be easily transported by rolling it while keeping the housing 2 tilted at an angle.

In addition, if a drum can is used as the housing 2, it is possible to ensure design while keeping manufacturing costs down.

The housing 2 may be transported by rolling it by placing the exercise portion on the road surface. In this case, in order to make it easier to roll the housing 2 on the road surface, the pre-treatment filter 41, post-treatment filter 43, UV sterilizer 80, and other devices installed outside the housing 2 as shown in FIG. 1B may be detachable from the housing 2. This makes it easier for staff of the business operator who installs the housing 2 (for example, the office floor of a business company, store staff, etc.) to change the position of the housing 2 by themselves without having to operate a specialized transportation staff to move the housing 2. For example, the housing 2 may be installed near the entrance of a store to have customers wash their hands with the hand-washing device 1 before entering the store. In this case, depending on the location where the housing 2 is installed, a situation may occur where it is difficult for users visiting the store to find it (and therefore difficult to increase the number of customers who wash their hands before entering the store). In contrast, in the above example, the store's management staff can search for a good location to install the housing 2 in order to provide an environment for customers to wash their hands.

In addition, an access hole 4 is provided on the outer periphery of the housing 2. Therefore, the access hole 4 can be used to easily perform maintenance of the hand washing device 1, such as disposing of the concentrated water with a high impurity content stored in the drainage tank 45 or replacing the reverse osmosis membrane 42.

In addition, a door 3 is provided at the access hole 4. Therefore, by keeping the door 3 closed during normal use, the appearance of the housing 2 can be improved.

In addition, the hand-washing device 1 is equipped with a hand-washing indicator 15, which suggests to the user the appropriate hand-washing time, thereby providing a high cleaning effect when the hand-washing device 1 is used. Furthermore, the use of the hand-washing device 1 can educate users about the appropriate hand-washing time.

In addition, the hand-washing indicator 15 is positioned on the top surface of the housing 2, outside the hand-washing basin 11, ensuring visibility of the hand-washing indicator 15 to a user who washes their hands using the hand-washing basin 11.

The hand-washing indicator 15 is formed on the upper edge of the hand-washing basin 11 so as to surround the basin. This allows for excellent design when the hand-washing indicator 15 is lit.

The post-processing filter 43 is disposed outside the housing 2 and is stored in a container whose interior is visible. This allows the user to visually check from the outside the state of the permeated water being filtered by the post-processing filter 43.

This allows the user to visually confirm that the water is being properly cleaned by the circulation unit 6, providing the user with a sense of security regarding the cleaning water purification function of the circulation unit 6.

The pre-treatment filter 41 is also placed outside the housing 2 and stored in a container whose interior can be seen. This makes it possible to visually compare the wastewater flowing into the pre-treatment filter 41 with the purified water flowing out of the post-treatment filter 43. This makes it possible to provide the user with a sense of security even more effectively.

The circulation unit 6 also includes an intermediate tank 44, a drainage tank 45, a water storage tank 46, a water discharge unit 20, and a drainage unit 30. This allows the intermediate water generated during the cleaning process of the drainage to be appropriately separated and stored.

In addition, because the hand-washing device 1 is equipped with a UV sterilization device 80, the user can sterilize portable items while washing their hands. Generally, portable items such as smartphones that are always carried and operated with the hands tend to have a high degree of bacterial adhesion to their surfaces, and habitual sterilization treatment is required for hygiene reasons. Sterilizing the surface of the smartphone with the UV sterilization device 80 can solve this problem.

The UV sterilization device 80 is also disposed on the side of the housing 2. This makes it easier for a user who uses the hand-washing device 1 to wash their hands to insert a portable item into the UV sterilization device 80.

The UV sterilization device 80 is disposed as part of the external module 7 that is attached to the outside of the housing 2. This improves the appearance of the housing 2. Also, separate installation work for attaching only the UV sterilization device 80 to the housing 2 is not required.

The hand-washing device 1 also includes a sterilization indicator 16. This allows the progress of the sterilization process to be displayed to the user, ensuring user convenience.

The sterilization indicator 16 is also located outside the hand washing basin 11 on the top surface of the housing 2. This ensures that the user can easily see the sterilization indicator 16.

The sterilization indicator 16 is also disposed between the hand washing basin 11 and the external module 7. This allows the user who has washed their hands in the hand washing basin 11 to easily check the progress status displayed by the sterilization indicator 16 while checking the status of the UV sterilization device 80 performing the sterilization process. This makes it possible to further ensure convenience for the user.

In addition, a step of operating the membrane filtration pump 47 is executed when the drainage pump 32 is operating. Therefore, membrane filtration processing can be performed using the reverse osmosis membrane 42 according to the generation of wastewater. This makes it possible to balance the flow rate of circulating water throughout the entire circulation system, given the limited capacity of each tank. It also makes it possible to carry out purification processing efficiently.

In addition, the pre-processing filter 41 and the post-processing filter 43 are stored in visible containers and disposed outside the housing 2 .
When the membrane filtration pump 47 is operating while the drainage pump 32 is operating, the user can simultaneously check from outside how the drainage pump 32 is operating, causing wastewater to flow into the pre-treatment filter 41, and how the membrane filtration pump 47 is operating, causing permeated water to flow into the post-treatment filter 43.

This allows the user to visually see how the circulating water is cleaning and circulating inside the housing 2, allowing the user to use the hand washing device 1 with peace of mind.

<Modification>
Next, a description will be given of a modified hand washing device 1. In this modified example, the control unit 60 has a function of automatically controlling the faucet 12 between the first state and the second state.

In this modified example, a motor capable of rotating the faucet 12 is provided at the base of the faucet 12. Then, in response to an external input to the control unit 60, the control unit 60 drives the motor to rotate the faucet 12 around the base, thereby switching between the first state and the second state.

In the first state, the control unit 60 performs the drainage process, the flushing process, and the water discharge process as described above.
On the other hand, in the second state, the control unit 60 operates the water discharge unit 20 without performing drainage and cleaning processes, and executes a water discharge process, which is a step of discharging water from the faucet 12 to remove water stored in the water tank 46.

According to this modified example, the control unit 60 automatically controls the first and second states of the faucet 12. In the first state, the hand washing device 1 can be used normally. In the second state, the wash water in the water tank 46 can be removed. In this way, by automatically controlling the orientation of the faucet 12, the wash water in the water tank 46 can be removed even more easily.

<Other Modifications>
Next, other modifications will be described.
In the above embodiment, the hand-washing device 1 is configured to include the UV sterilization device 80, but the present invention is not limited to this configuration. The hand-washing device 1 does not need to include the UV sterilization device 80. In this case, the hand-washing device 1 does not include the sterilization indicator 16.

The shape of the housing 2 is not limited to a cylindrical shape and can be changed as desired. For example, the shape of the housing 2 can be elliptical or the like. This makes it easy to move the housing 2 by rolling it with your hand, while preventing it from rolling too far even when you let go of it.

In the above embodiment, an example was described in which one infrared sensor is placed at the water outlet 13, but this is not limited to the above. Four infrared sensors may be placed in a cross shape at the water outlet 13. In this way, it is possible to determine in which direction a user who has discharged cleaning water from the water outlet 13 at the start of hand washing moved their hands after wetting them. If it is possible to determine the user's actions after wetting their hands, it is possible to determine whether the user has properly used the chemicals.

The hand-washing device 1 may thus sense how the user moves their hands near the water outlet 13 and store a history of the user's hand movements. By transmitting a log of the user's hand movements to an external server, the hand-washing device 1 can analyze the hand-washing behavior of multiple users who use the hand-washing device 1 in the location where the hand-washing device 1 is installed. For example, it may be possible to analyze whether the hand-washing behavior of users who use the hand-washing device 1 installed in a certain location tends to be appropriate.

A sensor such as a human presence sensor that determines the presence or absence of a person may be arranged on the front of the housing 2 of the hand-washing device 1. The human presence sensor makes it possible to obtain the time spent in front of the hand-washing device 1 by a user who uses the hand-washing device 1.

In the above embodiment, an example was described in which the pre-processing filter 41 and the post-processing filter 43 are provided outside the housing 2 and stored in a container whose inside is visible, but this is not limited to this configuration.

The pre-processing filter 41 and the post-processing filter 43 may be provided inside the housing 2. In this case, the pre-processing filter 41 and the post-processing filter 43 do not need to be stored in a container whose interior is visible.

The shape, structure, display mode, and control process of the hand-washing indicator 15 can be changed as desired. In addition, the hand-washing device 1 does not need to be equipped with a hand-washing indicator 15.

The shape, structure, display mode, and control process of the sterilization indicator 16 can be changed as desired. The sterilization indicator 16 may be provided in the UV sterilization device 80. In addition, the hand-washing device 1 does not need to be provided with the sterilization indicator 16.

The configuration of the purification unit 40 can be changed as desired. For example, the post-treatment filter 43 may be omitted, or another filter may be added.

Second Embodiment
A hand washing device according to a second embodiment will be described. In the second embodiment, maintenance of a hand washing device having a water circulation function will be described. In the description of the second embodiment, the term "hand washing device" includes the "hand washing device 1" described in the first embodiment, and refers to a hand washing device capable of performing maintenance work.

<Overall composition>
The overall configuration of the hand washing device according to the second embodiment will be described below. Fig. 11 is a block diagram showing an example of the configuration of the hand washing device according to the second embodiment.

As shown in FIG. 11, the hand-washing device includes a circulation unit 6, a chemical tank 50, a UV sterilization device 80, and a maintenance unit 9. Although not shown, the hand-washing device naturally includes a housing 2, a hand-washing basin 11 provided in a part of the housing, a faucet 12 for dispensing cleaning water, a dispenser 14, and the like, as in the first embodiment, to realize hand-washing.

The configurations of the circulation unit 6, chemical tank 50, and UV sterilization device 80 are the same as those in the first embodiment, so they will not be described repeatedly.

The maintenance unit 9 is a structure that controls maintenance work on the hand-washing device, and is connected to the circulation unit 6, the chemical tank 50, and the UV sterilization device 80. The configuration of the maintenance unit 9 is described below.

<Maintenance unit configuration>
Fig. 12 is a block diagram showing the configuration of the maintenance unit 9. As shown in Fig. 12, the maintenance unit 9 includes a first instructing unit 91, a second instructing unit 92, a storage unit 93, and a maintenance control unit 94.

The first instruction unit 91 is installed in a position on the housing that is visible to the user, and outputs first instruction information to inform the user of the need for maintenance of the hand-washing device. The need for maintenance here refers to whether or not maintenance work needs to be performed on the hand-washing device. The need for maintenance of the hand-washing device is determined based on the need for maintenance of each maintenance item, which will be described later.

The first indicator 91 is, for example, configured by the hand-washing indicator 15 of the first embodiment, and is formed on the upper edge of the hand-washing basin so as to surround the hand-washing basin. The first indicator 91 is also, for example, installed on the outside of the hand-washing basin 11 on the top surface of the housing 2, and may be, for example, the sterilization indicator 16 of the first embodiment. In other words, the first indicator 91 is not limited to the above example, as long as it is an indicator installed in a position visible to the user who is washing his or her hands. For example, the first indicator 91 may be installed in a position near the user, on the outside of the hand-washing basin 11 on the top surface of the housing 2.

The first indicator 91 is composed of a light-emitting element and can be lit in a number of lighting modes. The first indicator 91 changes the lighting mode based on the necessity for maintenance and outputs the first instruction information. The lighting mode here includes the lighting color, lighting brightness, or the presence or absence of blinking. For example, the first indicator 91 lights up blue when no maintenance is required for the hand washing device, lights up yellow when the maintenance time will arrive in a specified period of time, lights up red when the maintenance time will arrive soon, and blinks red when operation has stopped because maintenance was not performed, so as to output the first instruction information.

The first indicator 91 also operates when the user is washing his/her hands. For example, the first indicator 91 is the hand-washing indicator 15, which displays an estimate of the hand-washing time while the user is washing his/her hands, changes the illumination state based on the need for maintenance, and outputs the first instruction information.

By the first instruction unit 91 informing the user of the need for maintenance of the hand-washing device, the user can grasp the maintenance status or hygiene status of the hand-washing device. In addition, the first instruction unit 91 can also inform the manager of the hand-washing device of the need for maintenance, thereby encouraging the manager of the hand-washing device to perform appropriate maintenance work.

The second instruction unit 92 is installed inside the housing and outputs second instruction information to inform the user of the maintenance items that require maintenance. The maintenance items referred to here refer to the maintenance of the components that the hand washing device is equipped with and that require maintenance work.

Specifically, the maintenance items include, for example, at least one of the following items:
Replacement of the pre-treatment filter 41, reverse osmosis membrane 42, and post-treatment filter 43 included in the circulation unit 6 Refilling the chemical tank 50 with chemicals Discarding the concentrated water stored in the drainage tank 45 Refilling the chlorine tank 67 with chlorine Handling an abnormality in the UV sterilization device 80

The second instruction information indicates the type of maintenance item that requires maintenance, for example, that a medication needs to be replenished.

The second indicator 92 may be invisible to general users washing their hands during normal use. For example, the second indicator 92 is a display device that is installed inside the housing 2 and can be seen by the manager of the hand washing device when he opens the door 3, and displays the identification number of the maintenance item that requires maintenance.

The second indicator 92 is configured with a specified display device that can identify and display the maintenance content. For example, the second indicator 92 is configured with a seven-segment LED. The second indicator 92 identifies and displays the maintenance content by combining the illumination of seven LEDs.

The second instruction unit 92 may also be configured with a display device that displays an optical mark informing the user of the maintenance content. The optical mark is a mark that encodes the maintenance content, such as a barcode, a one-dimensional pixel code, or a two-dimensional pixel code. More specifically, for example, the second instruction unit 92 displays a QR code (registered trademark) that corresponds to the maintenance of the hand-washing device. The manager of the hand-washing device reads the QR code with a terminal device that the manager carries. The terminal device displays on a display the maintenance items that require maintenance and the work procedures for performing the maintenance items.

The second instruction unit 92 can inform the manager of the hand washing device of the specific maintenance items that require maintenance. This allows the manager of the hand washing device to carry out the maintenance work appropriately.

The storage unit 93 stores the program according to the second embodiment and data used by the maintenance control unit 94 described below. The data used by the maintenance control unit 94 includes, for example, the following data:

(a) Parameters for operating various hardware components of the hand washing device - Parameters related to pump operation (1) Pump operation values (voltage, current), cumulative operation time, pump maintenance records (2) Pump service life

- Parameters related to tank operation control (1) Tank capacity, material, and service life (2) Tank capacity fluctuation (3) Tank cumulative operating time, maintenance record

(2) User usage history (hand-washing time, frequency)

・Administrator data (1) Administrator attributes (gender, nationality, place of residence, industry)
(2) Administrator's management history (maintenance history, consumables purchase history)

In this embodiment, the memory unit 93 stores, for example, hand-washing device usage history data 931, component management data 932, filter sensing data 933, remaining liquid sensing data 934, and sterilization device usage history data 935.

Hand-washing device usage history data 931 is a database of hand-washing device usage history. Details will be described later.

Component management data 932 is a database that manages the necessity of each maintenance item based on the usage history of the hand washing device. Details will be described later.

The filter sensing data 933 is a database of sensors that detect the degree of wear of the pre-treatment filter 41, reverse osmosis membrane 42, and post-treatment filter 43 provided in the circulation unit 6. Details will be described later.

Liquid remaining amount sensing data 934 is a database of sensors that detect the remaining amount of liquid to determine the need for refilling or discarding the liquid. Details will be described later.

The sterilization device usage history data 935 is a database of the usage history of the UV sterilization device 80. Details will be described later.

The maintenance control unit 94 is realized by the processor and memory of the hand washing device. The maintenance control unit 94 performs the functions of various modules by executing a program stored in the memory unit 93, such as controlling the output of the first instruction unit 91 and the second instruction unit 92.

The data acquisition module 941 acquires data used to perform processing to control the output of the first instruction unit 91 and the second instruction unit 92 from the memory unit 93. For example, the data acquisition module 941 acquires filter sensing data 933 from the memory unit 93.

The first instruction control module 942 performs processing to control the output of the first instruction unit 91. For example, the first instruction control module 942 determines the necessity of maintenance for each maintenance item based on the data acquired by the data acquisition module 941, and controls the output of the first instruction unit 91 by determining the necessity of maintenance of the hand washing device.

The second instruction control module 943 performs processing to control the output of the second instruction unit 92. For example, the second instruction control module 943 determines the necessity of maintenance for each maintenance item based on the data acquired by the data acquisition module 941, and controls the output of the second instruction unit 92 by identifying the maintenance items that require maintenance.

<Data structure>
13 to 17 are diagrams showing the data structure of the database stored in the maintenance unit 9. FIG.
FIG. 13 is a diagram showing the data structure of the hand-washing device usage history data 931.

As shown in FIG. 13, each record of the hand washing device usage history data 931 includes information such as the item "Date and time" and the item "Details."

The "Date and Time" item is time information when the user is using the hand washing device to wash their hands, and stores the date and time.

The "detailed information" item is information about the operation of the hand washing device when washing hands, and stores, for example, the water discharge, drug discharge, and duration of water discharge of the hand washing device. The maintenance control unit 94 recognizes, for example, a series of water discharge, drug discharge, and water discharge actions that are close in time as one hand washing session.

The hand-washing device usage history data 931 allows the maintenance control unit 94 to grasp, for example, the number of times the hand-washing device has been discharged, the number of times medicine has been discharged, and the number of times hand-washing has occurred.

Figure 14 shows the data structure of component management data 932.

As shown in FIG. 14, each record of the component management data 932 includes information such as the item "component identification information," the item "date and time of last maintenance," the item "usable number of hand-washings," the item "number of hand-washings since last maintenance," and the item "remaining number of hand-washings."

The item "Component Identification Information" is information for identifying the component corresponding to each maintenance item, and stores the name and identification number of the component. Note that it is acceptable to store only the identification number.

The "Last maintenance date and time" item stores the date and time when maintenance was most recently performed on the component corresponding to each maintenance item.

The item "Number of hand-washing cycles that can be used" is the number of hand-washing cycles that can be used from immediately after maintenance is performed until the next maintenance period for the component corresponding to each maintenance item, and is information based on the attributes of each component. For example, if 50 hand-washing cycles can be performed from immediately after the pre-treatment filter is replaced until the next replacement is required, "50 times" is stored as the "number of hand-washing cycles that can be used" for the pre-treatment filter. The item "number of hand-washing cycles that can be used" may be preset for each component, or the number may be rewritten when the program for the hand-washing device is updated.

The item "Number of hand washings since last maintenance" is information regarding the number of hand washings performed since the last maintenance for the component corresponding to each maintenance item. The item "Number of hand washings since last maintenance" is determined based on the hand washing device usage history data 931. For example, based on the hand washing device usage history data 931, the number of times the medicine has been ejected from the medicine tank since the date and time of the last maintenance is accumulated and stored as the "number of hand washings since last maintenance" for the medicine tank.

The "remaining number of hand-washings" item is information about the remaining number of hand-washings that can be performed until the next maintenance is due for the component corresponding to each maintenance item. The "remaining number of hand-washings" item is the value obtained by subtracting the "number of hand-washings since the last maintenance" item from the "usable number of hand-washings" item. For example, if the pre-treatment filter can be used for 50 hand-washings with one replacement and 30 hand-washings have been performed since the last replacement, "20 times" will be stored as the "remaining number of hand-washings."

When a component corresponding to a maintenance item is replaced, the maintenance control unit 94, for example, reads out identification information from the replaced component. The component's identification information is stored, for example, in a wireless tag. The maintenance control unit 94, for example, reads out the identification information stored in the wireless tag using a reader function. The component's identification information may also be stored, for example, in a memory installed in the component. When the component is attached, the maintenance control unit 94 accesses the memory and reads out the stored identification information.

The maintenance control unit 94 adds the read identification information to a new record in the "component identification information" item of the component management data 932. At this time, the maintenance control unit 94 determines whether the read identification information complies with a predetermined rule. The predetermined rule may be changed depending on the release date of the component. If the read identification information does not comply with the predetermined rule, the maintenance control unit 94 notifies the person replacing the component that the replaced component is not appropriate.

The component management data 932 allows the maintenance control unit 94 to, for example, grasp the usage status of each component and grasp the remaining number of hand washings that can be performed until the next maintenance period arrives.

Figure 15 shows the data structure of filter sensing data 933.

As shown in FIG. 15, each record of the filter sensing data 933 includes information such as the item "sensor identification information," the item "date and time," and the item "sensing result."

The item "sensor identification information" is information for identifying each sensor, and stores the name and identification number of the sensor. Note that it is also possible to store only the identification information. The sensors include sensors installed in the flow path of each filter of the circulation unit 6, i.e., sensors installed in the upstream or downstream of each filter, specifically, pressure sensor 33, sensor unit 61, sensor unit 62, etc.

The "Date and Time" item stores the date and time when each sensor performed sensing.

The "Sensing Results" item is the detection results obtained by sensing with each sensor, and indicates the water pressure, flow rate, or electrical conductivity before or after the filter, etc.

The maintenance control unit 94 determines the degree of wear of each filter based on, for example, the sensing results of each sensor. For example, an EC/temperature sensor installed downstream of the reverse osmosis membrane 42 detects the electrical conductivity of the circulating water filtered by the reverse osmosis membrane 42 to determine the amount of impurities. In addition, if the pressure or flow rate exceeds a predetermined value, it determines that the reverse osmosis membrane 42 is clogged and needs to be replaced.

The filter sensing data 933 allows the maintenance control unit 94 to, for example, determine the degree of wear of each filter and the need to replace each filter.

Figure 16 shows the data structure of the remaining liquid sensing data 934.

As shown in FIG. 16, each record of the liquid remaining sensing data 934 includes information such as the item "component identification information," the item "date and time," and the item "sensing result."

The item "Component Identification Information" is information for identifying the components that store each liquid, and stores the name and identification number of the component. Note that it is also possible to store only the identification information. The liquids include the chemical stored in the chemical tank 50, the water stored in the intermediate tank 44, the concentrated water stored in the drainage tank 45, the water stored in the water storage tank 46, and the hypochlorous acid water stored in the chlorine tank 67.

The "Date and Time" item is time information when each sensor performed sensing, and stores the date and time. The sensor may be a water level sensor installed in each storage member to detect the remaining amount of liquid.

The "Sensing Results" item is the detection results obtained by sensing with each sensor, and indicates the liquid level in each storage component.

The maintenance control unit 94, for example, determines the remaining amount of each liquid based on the sensing results of each water level sensor and determines the need for refilling or disposal. For example, when the sensing result of the water level sensor installed in the chemical tank falls below a predetermined value, it determines that chemical refilling is necessary.

The liquid remaining amount sensing data 934 allows the maintenance control unit 94 to, for example, determine the remaining amount of each liquid and determine the need to replenish or discard each liquid.

Figure 17 shows the data structure of sterilization device usage history data 935.

As shown in FIG. 17, each record of the sterilization device usage history data 935 includes information such as the item "component identification information," the item "date and time," and the item "ultraviolet light irradiation pattern."

The item "Component Identification Information" is information for identifying the sterilization device, and stores the name and identification number of the component. Note that it is also possible to store only the identification information. Examples of sterilization devices include a UV sterilization device 80.

The "Date and Time" item stores the time information when the UV sterilization device 80 is operating, and stores the date and time.

The item "ultraviolet ray irradiation pattern" is information indicating the manner in which the UV sterilization device 80 irradiates ultraviolet rays. "Ultraviolet ray irradiation pattern" includes a pattern in which the UV sterilization device 80 irradiates ultraviolet rays all over the user's carried items, a pattern in which ultraviolet rays are concentrated in a specified area, and an abnormal state in which ultraviolet rays cannot be irradiated. The maintenance control unit 94 obtains, for example, information related to the usage history from the UV sterilization device 80.

The sterilization device usage history data 935 allows the maintenance control unit 94 to, for example, grasp the operating status of the sterilization device and grasp any abnormal conditions of the sterilization device.

<Operation>
The operation of controlling the first instruction section and the second instruction section by the maintenance unit will be described below.
FIG. 18 is a diagram showing a process flow for controlling the first instruction unit 91 and the second instruction unit 92.

In step S181, the maintenance control unit 94 acquires, for each maintenance item, the date and time of the maintenance, the number of hand-washings that can be tolerated from immediately after the maintenance until the next maintenance date, and the number of hand-washings since the previous maintenance. Specifically, the maintenance control unit 94 acquires the above information from the hand-washing device usage history data 931 and the component management data 932.

In step S182, the maintenance control unit 94 calculates the remaining number of hand washings that can be performed until the next maintenance time for each maintenance item. The maintenance control unit 94 calculates the remaining number of hand washings by subtracting the number of hand washings since the previous maintenance from the number of hand washings that can be performed.

In step S183, the maintenance control unit 94 determines the output mode of the first and second instruction units based on the remaining number of hand-washings. Specifically, the maintenance control unit 94 determines the necessity of maintenance for each maintenance item based on the remaining number of hand-washings for each maintenance item, and further determines the necessity of maintenance for the hand-washing device.

For example, the maintenance control unit 94 extracts the minimum value from the remaining number of hand-washings for each maintenance item. If the extracted minimum value is 15 times or more, the maintenance control unit 94 determines that the need for maintenance of each maintenance item and the hand-washing device is "no maintenance required."

In addition, if the minimum value is less than 15 times or is 5 times or more, the maintenance control unit 94 determines that the maintenance item corresponding to the minimum value and the need for maintenance of the hand washing device are "prepared for maintenance."

In addition, if the minimum value is less than 5 times or is 1 time or more, the maintenance control unit 94 determines that the maintenance item corresponding to the minimum value and the need for maintenance of the hand washing device are "maintenance required."

If the minimum value is 0 times, the maintenance control unit 94 stops the operation of the hand washing device. The maintenance control unit 94 determines the necessity of the maintenance item corresponding to the minimum value and the maintenance of the hand washing device as "will not restart unless maintenance is performed."

In step S184, the maintenance control unit 94 outputs the first and second instruction information in the output mode determined in step S183 by the first and second instruction units.

Specifically, if the necessity for maintenance of each maintenance item and the hand washing device is determined to be "no maintenance required" in step S183, the maintenance control unit 94, for example, lights up the first indication unit 91 in blue and displays information indicating that maintenance is not required on the second indication unit 92. For example, the second indication unit 92 displays the identification number "00" indicating that maintenance is not required.

In addition, in step S183, if the maintenance item corresponding to the minimum value and the need for maintenance of the hand washing device are determined to be "preparation for maintenance," the maintenance control unit 94, for example, lights up the first indication unit 91 in yellow and displays the identification number of the maintenance item in question in the second indication unit 92.

In addition, in step S183, if it is determined that the maintenance item corresponding to the minimum value and the need for maintenance of the hand washing device are "maintenance required," the maintenance control unit 94, for example, lights up the first indication unit 91 in red and displays the identification number of the maintenance item in question on the second indication unit 92.

In addition, in step S183, if it is determined that the maintenance item corresponding to the minimum value and the necessity for maintenance of the hand washing device are "not to be restarted unless maintenance is performed," the maintenance control unit 94, for example, causes the first indication unit 91 to flash in red and displays the identification number of the maintenance item in question in the second indication unit 92.

The threshold value for the remaining number of times is not limited to the above-mentioned 15 times and 5 times, and may be larger or smaller than these.
In addition, the alerts are issued in stages, such as "No maintenance required", "Preparing for maintenance", "Maintenance required", and "No restart unless maintenance is performed", but the stages of alerts are not limited to these. The number of stages may be more or less than these.

In addition, when the minimum value becomes 0, the operation of the hand-washing device is stopped; however, when the minimum value becomes 0, the operation of the hand-washing device does not necessarily have to be stopped. For example, it may be allowed to be used several times even after the minimum value becomes 0. If use continues without maintenance being performed after the minimum value becomes 0, the maintenance control unit 94 more strongly urges maintenance.

Figure 18 shows an example in which the first and second indicators are controlled based on the remaining number of hand-washing times, but this is not limited to the example. The first and second indicators may be controlled as follows. Note that any control process may be used for control, and multiple control processes may be used in combination.

(A) Control based on degree of wear of filter A sensor for detecting at least one of the flow rate, pressure, temperature, and electrical conductivity of water passing through the filter is provided in the flow path of the filter to detect the degree of wear of the filter. The maintenance unit 9 controls the outputs of the first indicator 91 and the second indicator 92 based on the degree of wear of the filter.

For example, the maintenance control unit 94 obtains the sensing results of each sensor from the filter sensing data 933 and determines the degree of wear of the pre-treatment filter 41, reverse osmosis membrane 42, post-treatment filter 43, and the like equipped in the circulation unit 6. For example, when the electrical conductivity detected by an EC/temperature sensor installed downstream of the reverse osmosis membrane 42 exceeds a predetermined value, the maintenance control unit 94 determines that the reverse osmosis membrane 42 is clogged and needs to be replaced. The maintenance control unit 94 lights up the first indicator 91 in red and displays the identification number corresponding to the reverse osmosis membrane 42 in the second indicator 92.

When a predetermined behavior, for example, a behavior indicating an abnormality in the filter, occurs in the sensing result acquired from the filter sensing data 933, the maintenance control unit 94 determines that an abnormality has occurred in the pre-treatment filter 41, the reverse osmosis membrane 42, the post-treatment filter 43, etc., provided in the circulation unit 6. The maintenance control unit 94 lights up the first indication unit 91 in red, and displays the identification number corresponding to the corresponding filter in the second indication unit 92.

(A) Control Based on the Remaining Amount of Liquid A sensor for detecting the water level is provided in a container for storing the liquid to detect the remaining amount of liquid. The maintenance unit 9 controls the outputs of the first indicator 91 and the second indicator 92 based on the remaining amount of liquid.

For example, a water level sensor that detects the remaining amount of the drug is provided in the drug tank 50, and when the sensing result of the water level sensor falls below a predetermined value, the maintenance control unit 94 determines that the drug needs to be replenished. The maintenance control unit 94 lights up the first indication unit 91 in red and displays the identification number corresponding to the drug tank 50 on the second indication unit 92.

(c) Control based on abnormality detection result of the sterilization device A detection means for detecting an abnormality occurring in the sterilization device is installed. The maintenance unit 9 controls the output of the first instruction unit 91 and the second instruction unit 92 based on the abnormality detection in the sterilization device.

For example, the maintenance control unit 94 obtains the usage history of the UV sterilization device 80 from the UV sterilization device 80. When an abnormality in the UV sterilization device 80 is detected in the irradiation of ultraviolet rays, the maintenance control unit 94 determines that maintenance of the UV sterilization device 80 is required. The maintenance control unit 94 lights up the first indicator 91 in red and displays the identification number corresponding to the UV sterilization device 80 in the second indicator 92.

For example, the maintenance control unit 94 also acquires the usage history of the UV sterilization unit 22 from the UV sterilization unit 22. When the UV sterilization unit 22 reports that an abnormality has occurred in the irradiation of ultraviolet light, the maintenance control unit 94 determines that maintenance of the UV sterilization unit 22 is necessary. The maintenance control unit 94 lights up the first indicator 91 in red and displays the identification number corresponding to the UV sterilization unit 22 in the second indicator 92.

Through the above series of processes, the maintenance unit 9 can properly inform the user of information related to the maintenance of the hand washing device through the first instruction unit 91 and the second instruction unit 92. This allows the maintenance staff to properly and efficiently perform the maintenance of the hand washing device.

The detection of abnormality by the maintenance unit 9 is not limited to the above. When a predetermined behavior, for example, behavior indicating an abnormality in the water discharge unit 20, the drainage unit 30, or the purification unit 40, occurs in the sensing results acquired from the filter sensing data 933, the maintenance control unit 94 determines that an abnormality has occurred in the water discharge unit 20, the drainage unit 30, or the purification unit 40. The maintenance control unit 94 lights up the first indication unit 91 in red, and displays the identification number corresponding to the corresponding unit in the second indication unit 92.

<Display example>
Display examples of the first indicator 91 and the second indicator 92 will be described.

Figure 19 is a diagram showing an example of the display mode of the first indicator. In Figure 19, the first indicator 91 is configured by the hand-washing indicator 15 of the first embodiment, and while displaying an estimate of the hand-washing time while the user is washing their hands, notifies the user of the need for maintenance of the hand-washing device through different lighting modes.

For example, when no maintenance of the hand-washing device is required, the hand-washing indicator 15 lights up blue, and when maintenance of the hand-washing device is required, the hand-washing indicator 15 lights up red. As shown in FIG. 19, when the dispenser 14 is operating, the hand-washing indicator 15 lights up in order clockwise from the LED lights located near the base of the faucet 12 when viewed from above to indicate an estimate of hand-washing time, and lights up in a specified color to indicate the need for maintenance of the hand-washing device.

This makes it possible to notify the user of the need for maintenance of the hand-washing device in a manner that is easily visible to the user while the user is washing their hands. This allows the user to understand the maintenance status or hygiene status of the hand-washing device. In addition, the need for maintenance can be notified to the administrator of the hand-washing device, urging the administrator to carry out maintenance work appropriately.

Figure 20 is a diagram showing an example of the display mode of the second indicator. In Figure 20, the second indicator 92 is made up of two 7-segment LEDs, and notifies the user of the maintenance items that require maintenance by displaying the identification numbers of the maintenance items.

For example, as shown in FIG. 20, if it is determined that replacement of the pre-processing filter 41 is necessary, the second indication unit 92 displays the identification number "02" of the pre-processing filter 41. If there is no maintenance item that requires maintenance, the identification number "00" may be displayed. If a technical error occurs that cannot be resolved by replacement or the like, for example, a preset identification number "88" may be displayed.

This allows the administrator of the hand washing device to be informed of the specific maintenance items that require maintenance, allowing the administrator of the hand washing device to carry out the maintenance work appropriately.

The maintenance control unit 94 may also determine whether a replaced component, such as a filter, is appropriate based on the "sensing result" item of the filter sensing data 933. For example, the flow characteristics of the pre-treatment filter 41, reverse osmosis membrane 42, and post-treatment filter 43 change depending on the materials used. In other words, the pressure or flow rate detected in the upstream or downstream of the filter changes depending on the materials used.

The maintenance unit 9 stores in advance in the memory unit 93 a general pressure value or flow rate value, etc., detected when the appropriate pre-treatment filter 41, reverse osmosis membrane 42, and post-treatment filter 43 are installed, with a predetermined range. When the filter is replaced, the maintenance control unit 94 controls, for example, the water discharge unit 20 to discharge cleaning water from the faucet 12. The maintenance control unit 94 determines whether the pressure value or flow rate value detected at this time falls within the range of the preset pressure value or flow rate value. If it does not fall within the range, the maintenance control unit 94 notifies the person replacing the replaced parts that the replaced parts are not appropriate. The preset pressure value or flow rate value, etc. may be updated to the latest value when the program is updated.

Third Embodiment
Next, a third embodiment will be described. In the third embodiment, collection of data related to hand washing will be described. Note that the same components as those in the first and second embodiments are denoted by the same reference numerals and will not be described.

<Overall configuration of information processing system 1000>
21 is a block diagram showing the overall configuration of the information processing system 1000. The information processing system 1000 is a system for collecting and analyzing data such as data related to hand washing, data related to applications, and data related to maintenance.

As shown in FIG. 21, the information processing system 1000 includes a hand-washing device 1, an information processing device 200, a monitoring device 300, and a maintenance terminal 400. The information processing system 1000 may be configured to include multiple hand-washing devices 1. The hand-washing device 1, the information processing device 200, the monitoring device 300, and the maintenance terminal 400 are connected to a network 500 using a wired or wireless communication standard. The hand-washing device 1 and the information processing device 200 are connected to each other so that they can communicate with each other via the network 500. In this embodiment, the information processing system 1000 includes the monitoring device 300 and the maintenance terminal 400, but the information processing system 1000 does not necessarily have to include the monitoring device 300 and the maintenance terminal 400.

The hand-washing device 1 is a portable device that can be installed anywhere and allows a user to wash their hands. The hand-washing device 1 is equipped with a communication unit 100. The communication unit 100 is configured to control communication with the information processing device 200.

The communication unit 100 acquires first data, which is data related to hand washing, and transmits it to the information processing device 200. The first data includes, for example, data on the usage history of the hand washing device 1, data obtained by monitoring the hand washing device 1 acquired from the monitoring device 300, aggregated data created based on the detected data, and other data. The communication unit 100 also acquires second data, which is data related to maintenance, and transmits it to the information processing device 200. The second data includes, for example, data detected by a group of sensors installed in the hand washing device 1, data managing replacement parts, etc.

The monitoring device 300 is a device that monitors the surroundings of the hand-washing device 1. The monitoring device 300 is installed in a position where it can monitor the surroundings of the hand-washing device 1. For example, the monitoring device 300 may be a camera or the like that is placed in the space where the hand-washing device 1 is installed (such as the lobby or entrance of a building). When the hand-washing device 1 is installed in a space used by unspecified users, the monitoring device 300 may be a monitoring camera or the like that is installed in advance in the space, or may be a device that is installed according to the installation location of the hand-washing device 1. The monitoring device 300 is realized by an imaging device such as a camera, or a sensor such as a human sensor or an infrared sensor. The monitoring device 300 transmits the acquired monitoring data, for example, image data or sensor data, to the hand-washing device 1.
By photographing the area around the hand-washing device 1 with a camera, it is possible to determine based on the captured image whether the user is washing their hands properly (for example, whether each step of the process is being carried out: (1) wetting the hands, (2) applying chemicals to the skin, (3) massaging the hands, and (4) rinsing them off. Alternatively, as shown in the "Hand-washing Evaluation" section described below, an infrared sensor attached to the hand-washing device 1 etc. can be used to evaluate how the user moves their hands when washing their hands), whether there is a malfunction (described below), whether maintenance is needed (the hand-washing device 1 outputs (e.g., emits light) an indication that maintenance is needed, etc.), and by sensing the area around the hand-washing device 1 with a sensor such as a human presence sensor, it is possible to obtain information such as whether a person is in front of the hand-washing device 1 and how many seconds they stayed in front of the hand-washing device 1 while washing their hands.
The monitoring device 300 may also be configured to detect the size of the user's hands from a sensor or monitoring image data of handwashing. In this case, the monitoring device 300 transmits the detected hand size to the handwashing device 1. The control unit 60 according to the first embodiment, for example, ejects an amount of medicine according to the detected hand size. Note that the monitoring data may be transmitted from the monitoring device 300 to the handwashing device 1, and the hand size may be detected by the handwashing device 1. Also, the hand size may not be detected directly, but may be estimated from the user's attributes such as height, sex, age, etc.

The maintenance terminal 400 is a device owned by a person in charge of maintaining the hand-washing device 1. For example, the maintenance terminal 400 is a mobile terminal such as a smartphone, tablet, or laptop PC, or a stationary computer. When a maintenance person performs maintenance, the maintenance terminal 400 transmits second data, which is data related to the maintenance, to the information processing device 200. The maintenance terminal 400 may also input setting data to the hand-washing device 1. The setting data includes, for example, reference data for detecting an abnormality in the circulation unit 6, the number of times that the replacement parts can be used, a threshold value for determining the need for maintenance (for example, the number of times that a replacement part is used, a threshold value for comparing with an evaluation value of the quality of water purified by a filter, etc.), information for confirming whether the replacement part is a genuine part (information assigned to a genuine part, etc.), a distance for an infrared sensor to detect the user's fingers moving away, a threshold value used to control the hand-washing device 1, or a reference value.

The information processing device 200 acquires the first data transmitted from the hand-washing device 1 and the second data transmitted from the hand-washing device 1 or the maintenance terminal 400, and stores the acquired data. The information processing device 200 analyzes the stored data. The information processing device 200 may be composed of one or more devices, and each of the multiple devices may be responsible for a function and perform processing, thereby being recognized as a single information processing device.

The transmission control module 122 controls the process in which the communication unit 100 transmits signals to an external device according to a communication protocol. Specifically, the transmission control module 122 transmits first data related to hand washing or second data related to maintenance to the information processing device 200.

The data acquisition module 123 acquires data to be transmitted to the information processing device 200 from the memory unit 93. For example, the data acquisition module 123 acquires hand-washing device usage history data 931, component management data 932, filter sensing data 933, remaining liquid sensing data 934, or sterilization device usage history data 935 from the memory unit 93. The data acquisition module 123 may aggregate the acquired data for each predetermined period to create aggregated data. The predetermined period is, for example, one day, one week, etc. The aggregated data includes, for example, the number of hand-washings performed during the predetermined period, the amount of medicine used during the predetermined period, etc. The data acquisition module 123 also acquires monitoring data acquired by the monitoring device 300 and stored in the memory unit 93.

The input module 124 accepts input of setting data from the maintenance terminal 400.

The setting module 125 performs settings related to the control of the hand washing device 1 based on the input setting data.

The "amount used" item indicates the amount of substance used in one handwashing session. The "amount used" item includes sub-items such as "amount of water," "amount of drug," and "amount of energy."

The "Water Volume" item stores the flow rate of water used in one hand washing session. The water volume is calculated, for example, based on the time the water discharge pump 21 was operating when the water was discharged. A predetermined value based on the operating time of the water discharge pump 21 may be set for the water volume. For example, "high," "normal," or "low" is set depending on the length of operating time of the water discharge pump 21. Note that if the water discharge volume is fixed, the water volume is calculated based on the number of times the water discharge pump 21 is operated.

The item “medicinal amount” stores the amount of the medical agent used in one hand washing. In this embodiment, since the amount of the medical agent discharged in one time is fixed, the medical agent amount is calculated based on the number of times the medical agent pump 51 is operated.
The control unit 60 according to the first embodiment may vary the amount of drug discharged at one time depending on the size of the hand. That is, the control unit 60 increases the amount of drug for a user with a large hand and decreases the amount of drug for a user with a small hand. In this case, the amount of drug is calculated based on, for example, the number of times the drug pump 51 is operated and the amount of drug discharged during hand washing.

The item "Amount of energy" stores the amount of energy used in one hand washing session. The amount of energy is, for example, the amount of electricity used in one hand washing session. The amount of energy is calculated, for example, from the total amount of electricity used in the water discharge pump 21, the chemical pump 51, and the UV sterilization unit 22 driven in one hand washing session.

The item "purified water volume" stores the volume of water purified by the circulation unit 6. The purified water volume is calculated, for example, based on the flow rate detected by the sensor unit 62 during hand washing.

The item "Purified water quality" stores the quality of the water purified by the circulation unit 6. The purified water quality is obtained, for example, based on the difference between the sensing result detected by the sensor unit 61 and the sensing result detected by the sensor unit 62.

Figure 29 is a diagram showing an example of the data structure of the sterilization device usage data DB235. As shown in Figure 29, each record of the sterilization device usage data DB235 includes an item "model", an item "date and time", an item "irradiation pattern", an item "irradiation time", an item "user ID", etc.

The item "Model" stores the model of the portable item that has been sterilized.

<Operation>
<Data Collection by Communication Unit 100>
Next, a data transmission process by the communication unit 100 in this embodiment will be described with reference to Fig. 34. Fig. 34 is a flow chart showing an example of an operation performed when the communication unit 100 transmits data to the information processing device 200.

In step S111, the communication control unit 120 reads data from the memory unit 93 of the hand-washing device 1. Specifically, the communication control unit 120 reads, for example, at a predetermined timing, records that have not yet been transmitted to the information processing device 200 from the hand-washing device usage history data 931, the component management data 932, the filter sensing data 933, the remaining liquid sensing data 934, or the sterilization device usage history data 935 stored in the memory unit 93 of the hand-washing device 1. The predetermined timing is, for example, a preset time, a preset period, etc.
Furthermore, when a tendency for an abnormality to occur in the circulation unit 6 is detected, the communication control unit 120 reads out the record of the filter sensing data 933 at that time. A case where a tendency for an abnormality to occur in the circulation unit 6 is detected refers to, for example, a case where the maintenance control unit 94 in the second embodiment determines, based on the sensing result acquired from the filter sensing data 933, that an abnormality has occurred in the pre-treatment filter 41, the reverse osmosis membrane 42, the post-treatment filter 43, or the like provided in the circulation unit 6.
Furthermore, the communication control unit 120 reads out records of the hand-washing device usage history data 931 and the filter sensing data 933, etc., added during each predetermined period, and creates aggregated data based on the read out records. The aggregated data may be created by the information processing device 200 based on the data transmitted by the communication control unit 120.
Furthermore, the communication control unit 120 reads out, at a predetermined timing, monitoring data that has not yet been transmitted to the information processing device 200 from among the monitoring data stored in the storage unit 93. The predetermined timing is, for example, a preset time or a preset cycle. The timing of reading out the monitoring data may be less frequent than the timing of reading out data from the databases 931 to 935.

In step S112, the communication control unit 120 transmits the acquired records of hand washing device usage history data 931, component management data 932, filter sensing data 933, etc., monitoring data, and aggregated data to the information processing device 200 as first data. In addition, the communication control unit 120 transmits the acquired records of component management data 932, filter sensing data 933, liquid remaining amount sensing data 934, etc. to the information processing device 200 as second data.

This enables the hand-washing device 1 to transmit data related to hand-washing (first data) to the information processing device 200, such as the number of times hand-washing was performed in a day, the amount of water used in hand-washing, the amount of detergent used in hand-washing, the time taken for hand-washing, information about dirt, the time when hand-washing was performed, and location information when hand-washing was performed. In addition, the hand-washing device 1 can transmit data related to maintenance (second data) to the information processing device 200, such as the maintenance date and time, sensing results required for maintenance, items to be replaced, and failure data.

<Data collection by information processing device 200>
Next, a data collection process by the information processing device 200 in this embodiment will be described with reference to Fig. 35. Fig. 35 is a flowchart showing an example of an operation performed by the information processing device 200 when collecting data.

In step S121, the reception control unit 221 of the information processing device 200 receives the first data and the second data from the communication unit 100.

The reception control unit 221 also receives third data input from a portable item (a communication device such as a smartphone or a smartwatch) via, for example, an application related to the hand-washing device 1. The third data includes data input by the user when using the hand-washing device 1, or data read when the portable item is inserted into the UV sterilization device 80. More specifically, the third data includes personal data of the user registered in advance in the application, and data such as the user's evaluation of hand-washing with the hand-washing device 1 input by the user after using the hand-washing device 1. Note that the third data does not have to be received directly from the user's portable item. The third data may be managed by an external server or the like, and the information processing device 200 may obtain the third data by accessing the server.

In step S122, the control unit 220 stores the received first data, second data, and third data in the target database stored in the memory unit 230.

<Analysis of monitoring data of information processing device 200>
Next, a monitoring data analysis process by the information processing device 200 in this embodiment will be described with reference to Fig. 36. Fig. 36 is a flowchart showing an example of an operation performed by the information processing device 200 when analyzing monitoring data.

In step S131, the analysis unit 223 analyzes at least one of the image data and sensor data obtained from the monitoring device 300 to obtain the user who used the hand washing device 1, the usage time, the location of the malfunction, etc.
Specifically, when the analysis unit 223 receives image data from the communication unit 100, the analysis unit 223 performs image analysis on the image data. As a result, the analysis unit 223 extracts the user who used the hand-washing device 1, and estimates the gender, generation (age), time taken for hand-washing of the user, etc.
Furthermore, the analysis unit 223 performs image analysis on the image data received from the communication unit 100 to detect faults or failures in the hand-washing device 1 due to dirt, damage, etc. The analysis unit 223 also performs image analysis on the image data received from the communication unit 100 to detect the situation around the hand-washing device 1, such as the number of people, etc.
Furthermore, when the analysis unit 223 receives sensor data from the communication unit 100, the analysis unit 223 analyzes the sensor data. As a result, the analysis unit 223 extracts the user, detects the location of a malfunction or failure, calculates the time the hand-washing device 1 is used, and the like.

In step S132, the control unit 220 stores the data obtained by the analysis in the target database stored in the memory unit 230.

<Analysis processing>
Next, the analysis process by the information processing device 200 in this embodiment will be described with reference to Fig. 37. Fig. 37 is a flowchart showing an example of the operation when the information processing device 200 analyzes data.

First, for example, a case where the purpose of analysis is to understand demographic trends will be described.
In step S141, the formatter 224 extracts data corresponding to the analysis purpose from the data stored in each database, and formats the extracted data into a form suitable for the desired analysis.

Specifically, for example, the shaping unit 224 extracts data for each item from the installation data DB 232, the aggregated data DB 233, the hand-washing data DB 234, the user data DB 236, etc. The shaping unit 224 selects necessary data from the extracted data, rearranges the data in chronological order, and classifies the data by area.

In step S142, the analysis unit 223 performs an analysis regarding hand-washing based on the formatted data.
Specifically, for example, the analysis unit 223 obtains the change over time in the number of times the hand-washing device 1 is used for each of a plurality of areas based on the shaped data. The analysis unit 223 compares the change in the number of times the hand-washing device 1 is used for each area.
In step S143, output unit 225 outputs the analysis results obtained by analysis unit 223. Specifically, output unit 225 presents the comparison results acquired by analysis unit 223 to the operator of information processing device 200. By referring to the comparison results for each area of the change over time in the number of times of use, the operator of information processing device 200 can grasp the demographic trends between areas. In addition, the number of times hand-washing device 1 has been used, the distribution of users who have used hand-washing device 1, etc. may be output as analysis results for each area.

Next, for example, a case where the analysis purpose is (i) grasping the prevalence status of hand washing habits will be described.
In step S141, for example, the shaping unit 224 extracts data for each item from the installation data DB 232, the aggregated data DB 233, the hand-washing data DB 234, the user data DB 236, the monitoring data DB 239, etc. The shaping unit 224 selects necessary data from the extracted data, rearranges the data in chronological order, and classifies the data by area.

In step S142, the analysis unit 223 acquires, for example, the change over time in the number of times the hand-washing device 1 is used and the change over time in the number of users with high hand-washing ratings for each of a plurality of areas based on the shaped data. The analysis unit 223 arranges the data in such a way that the expansion/contraction of areas with high usage and the expansion/contraction of areas with a large number of users with high hand-washing ratings can be grasped.
In step S143, the output unit 225 presents the analysis result acquired by the analysis unit 223 to the operator of the information processing device 200. The operator of the information processing device 200 can grasp the prevalence of hand washing habits by referring to the enlargement/reduction of areas with high usage counts and the enlargement/reduction of areas with a large number of users who have a high hand washing evaluation.

Next, for example, a case where the analysis purpose is (d) grasping user trends will be described.
In step S141, for example, the shaping unit 224 extracts data for each item from the installation data DB 232, the tabulated data DB 233, the hand-washing data DB 234, the user data DB 236, the monitoring data DB 239, etc. The shaping unit 224 selects necessary data from the extracted data, rearranges the data in chronological order, and classifies the data by generation, occupation, etc.

In step S142, the analysis unit 223 acquires hand-washing characteristics for each classified cluster based on, for example, the shaped data. The analysis unit 223 compares the hand-washing characteristics for each cluster.

In step S143, the output unit 225 presents the comparison results obtained by the analysis unit 223 to the operator of the information processing device 200. The operator of the information processing device 200 can understand the tendencies of users of the hand-washing device 1 by referring to the hand-washing characteristics of each cluster.

The analysis unit 223 may also analyze the data using a trained analysis model.

<Estimation process>
Next, the estimation process by the information processing device 200 in this embodiment will be described with reference to Fig. 38. Fig. 38 is a flowchart showing an example of the operation of the information processing device 200 when estimating a predetermined event.

First, for example, a case where the analysis purpose is (c) understanding the state of various filters in the hand washing device 1 will be described.
In step S141, the formatter 224 extracts data corresponding to the analysis purpose from the data stored in each database, and formats the extracted data into a form suitable for the desired analysis.
Specifically, for example, the shaping unit 224 extracts data for each item from the product data DB 231, the installation data DB 232, the aggregation data DB 233, the hand-washing data DB 234, the maintenance data DB 237, the environment data DB 238, etc. The shaping unit 224 selects necessary data from the extracted data and rearranges the data in chronological order.
In step S152, the analysis unit 223 estimates the states of various filters based on the shaped data.
Specifically, for example, the analysis unit 223 acquires past sensing results that are similar to the behavior of the current sensing result based on the shaped data, and estimates the wear tendency of the filter by referring to the acquired past sensing results and past maintenance data.
In step S153, the output unit 225 outputs the estimation result by the analysis unit 223. Specifically, the output unit 225 presents the wear tendency of the filters estimated by the analysis unit 223 to the operator of the information processing device 200. The operator of the information processing device 200 can grasp the state of various filters by referring to the wear tendency of the filters.

Next, a case where the analysis purpose is (e) grasping the location of the occurrence of a failure will be described.
In step S141, the shaping unit 224 extracts data for each item from, for example, the product data DB 231, the installation data DB 232, the aggregated data DB 233, the hand-washing data DB 234, the maintenance data DB 237, the environmental data DB 238, etc. The shaping unit 224 selects necessary data from the extracted data and rearranges the data in chronological order.
In step S152, the analysis unit 223 acquires past sensing results similar to the behavior of the current sensing result, for example, based on the shaped data. The analysis unit 223 refers to the acquired past sensing results and past maintenance data to estimate a portion at which a failure may occur.
In step S153, the output unit 225 presents the part in which a failure is likely to occur, which is estimated by the analysis unit 223, to the operator of the information processing device 200. By referring to the part in which a failure is likely to occur, the operator of the information processing device 200 can grasp in advance the location where the failure will occur.

Next, for example, a case where the analysis purpose is (f) grasping the optimal installation location will be described.
In step S141, the shaping unit 224 extracts data for each item from, for example, the product data DB 231, the installation data DB 232, the aggregated data DB 233, the hand-washing data DB 234, the maintenance data DB 237, the environmental data DB 238, etc. The shaping unit 224 selects necessary data from the extracted data and rearranges the data in chronological order.
In step S152, the analysis unit 223 acquires, for example, based on the shaped data, changes over time in the number of times the hand-washing device 1 is used, increases or decreases in the number of times the hand-washing device 1 in the vicinity is used after a specific hand-washing device 1 is installed, etc. The analysis unit 223 compares the acquired trends with the current situation, and estimates areas (locations) where the number of hand-washings is predicted to increase sharply in the future.
In step S153, the output unit 225 presents the area estimated by the analysis unit 223 to the operator of the information processing device 200. The operator of the information processing device 200 can grasp the optimal installation location by referring to the presented area.

Next, for example, a case where the purpose of analysis is (g) formulation of an optimal sanitation policy will be described.
In step S141, the shaping unit 224 extracts data for each item from, for example, the product data DB 231, the installation data DB 232, the aggregated data DB 233, the hand-washing data DB 234, the maintenance data DB 237, the environmental data DB 238, etc. The shaping unit 224 also acquires hygiene policies issued in the past by a given local government, the dates of issuance of the hygiene policies, index values representing the hygiene environment, etc. The shaping unit 224 selects necessary data from the extracted data and rearranges it in chronological order.
In step S152, the analysis unit 223 obtains a predetermined correlation, for example, based on the shaped data, by comparing changes over time in the index value, etc. after the issuance of the hygiene policy with changes over time in the number of uses of the hand-washing device 1, etc. The analysis unit 223 applies the obtained correlation to the current situation to estimate a hygiene policy suitable for the current situation.
In step S153, the output unit 225 presents the hygiene policy estimated by the analysis unit 223 to the operator of the information processing device 200. The operator of the information processing device 200 can formulate an optimal hygiene policy by referring to the presented hygiene policy.

The analysis unit 223 may perform the estimation process using a trained model. In this case, the trained model is generated, for example, by a machine learning model that uses a specific trend as input data and trains results that are highly related to this trend as correct output data.

<Analysis model learning>
Next, the analytical model learning process performed by the information processing device 200 in this embodiment will be described with reference to Fig. 39. Fig. 39 is a flowchart showing an example of the operation performed by the information processing device 200 when training an analytical model.

In step S161, the learning unit 226 acquires data corresponding to the analysis purpose of the analysis model from each database.

In step S162, the learning unit 226 learns parameters of the analysis model so that an analysis result is output when at least one of the first data, the second data, and the third data is input.
In step S<b>163 , the learning unit 226 stores the acquired parameters in the storage unit 230 .

<Analysis of users in the space where the hand washing device 1 is installed>
(h) The information processing device 200 may output user tendencies as analysis results for unspecified users who use the space in which the hand-washing device 1 is installed, based on information about users who wash their hands using the hand-washing device 1.
For example, the information processing device 200 analyzes the tendency of users who use the hand-washing device 1 (e.g., age group, gender, etc.) based on the user data DB 236, the installation data DB 232, etc., and outputs the tendency of users in the space in which the hand-washing device 1 is installed as an analysis result. For example, even in a space where a check-in operation for using a facility is not accepted from a user, the hand-washing device 1 can be installed in a store or the like in the facility, and the user can use the hand-washing device 1 to analyze the tendency of users who visit the store or the like. For the store or the like, data for analyzing the tendency of users who visit the store or the like can be accumulated through hand-washing with the hand-washing device 1 before the timing when the user who visits the store or the like confirms the purchase, such as during payment processing.
The hand-washing device 1 may also be linked to an information terminal for accepting user information (e.g., a terminal for accepting waiting lists at a store, etc.). For example, in response to accepting input of user information at the information terminal (e.g., inputting user information when visiting a store), a notification may be sent to encourage the user to wash their hands using the hand-washing device 1. Through the above processing, the information processing device 200 may update the user data DB 236.

(i) The information processing device 200 may be placed in the space in which the hand-washing device 1 is installed, and may analyze a preferable location for placing the hand-washing device 1.
For example, the information processing device 200 compares the number of users using the space (e.g., by analyzing images captured by the surveillance camera) with the history of users who washed their hands using the hand-washing device 1, based on the video footage from a surveillance camera installed in the space and the history of hand-washing using the hand-washing device 1. Depending on the comparison result (e.g., when the number of times the hand-washing device 1 has been used is small compared to the number of users), the information processing device 200 may notify the user of the information processing device 200 to move the hand-washing device 1 to a position that is easier to use.
As described above, the information processing device 200 may provide the function of performing these analyses and the analysis results, etc., to the business operator that installs the hand-washing device 1. Here, the analysis function that the information processing device 200 provides to the business operator may be set according to the fee plan in the contract for the business operator to use the hand-washing device 1.

As described above, according to the information processing system of this embodiment, first data related to hand washing is acquired from the hand washing device 1, which is portable and can be installed anywhere, and the acquired first data is transmitted to the information processing device 200. The information processing device 200 acquires the first data from the hand washing device 1, which can be installed anywhere, and stores the acquired first data, making it possible to efficiently collect data related to hand washing.

Furthermore, hand-washing devices that are portable and can be installed anywhere may be installed in multiple locations in the information processing system. By configuring it in this way, data related to hand-washing can be collected more efficiently.

In addition, hand-washing devices other than hand-washing devices that are portable and can be installed anywhere may be installed so that data can be collected. By configuring it in this way, data related to hand-washing can be collected more efficiently.

＜Other＞
Although the preferred embodiment of the present disclosure has been described above, the present disclosure is not limited to the specific embodiment, and the present disclosure includes the invention described in the claims and its equivalents. In addition, the configurations of the devices described in the above embodiments and modifications can be combined as appropriate as long as no technical contradiction occurs.

In the above embodiment, the communication unit 100 communicates directly with the monitoring device 300 and the maintenance terminal 400, but this is not limited to the above. The communication unit 100, the monitoring device 300, and the maintenance terminal 400 may be configured to communicate via the network 500.

In addition, in the above embodiment, the communication unit 100 is configured as an internal function of the hand-washing device 1, but this is not limited to the above. The communication unit 100 may be configured as an external device connected to the hand-washing device 1.

In addition, the collection of each device (e.g., communication unit 100 and information processing device 200) constituting information processing system 1000 can be understood as a single "information processing device." In other words, information processing system 1000 can be realized as a collection of multiple devices, and the allocation of multiple functions for realizing information processing system 1000 can be appropriately determined based on the processing capacity of the hardware of each device.

Fourth Embodiment
A hand washing device according to a fourth embodiment will be described. In the fourth embodiment, management of a hand washing device that is portable and can be installed anywhere will be described.

The hand-washing device 1A described in this embodiment can be installed in various locations, such as indoors and outdoors. The hand-washing device 1A is installed indoors, for example, near the entrance to a building, in the office space of a business operator occupying the building, or near the entrance to a store. It is assumed that the hand-washing device 1A will be managed by the manager of the facility in which the hand-washing device 1A is installed.

<Overall configuration of hand washing device 1A>
The overall configuration of the hand washing device 1A according to the fourth embodiment will be described below. Fig. 40 is a rear perspective view of the hand washing device 1A according to the fourth embodiment.

The hand-washing device 1A according to the fourth embodiment is configured in the same way as the hand-washing device 1 according to the first embodiment, except for the housing 2A, horizontal shaft 101, and running wheels 102A and 102B, so a description thereof will be omitted. The housing 2A, horizontal shaft 101, and running wheels 102A and 102B of the hand-washing device 1A will be described below.

As shown in FIG. 40, through holes 24A and 24B are formed on the outer peripheral surface of the housing 2A at a position close to the bottom surface of the rear side (door 3 side) of the hand washing device 1A. The axis passing through the through holes 24A and 24B is configured to extend parallel to the bottom surface.

The horizontal shaft 101 is installed so as to pass through the through holes 24A and 24B and enter the interior of the housing 2A. The running wheels 102A and 102B are rotatably attached to both ends of the horizontal shaft 101. For example, the horizontal shaft 101 is a rod-shaped shaft fixed to the housing 2A, and the running wheels 102A and 102B are casters attached to both ends of the horizontal shaft 101 and capable of moving the hand washing device 1A in the forward and backward directions.

The horizontal shaft 101 and running wheels 102A and 102B form a movement assistance unit that assists the movement of the hand-washing device 1A. This makes it possible to easily move the hand-washing device, which is portable and can be installed anywhere, and makes it easier to manage the hand-washing device.

In FIG. 40, the horizontal shaft 101 and running wheels 102A, 102B are positioned at the rear of the hand-washing device 1A, but this is not limited thereto and they may be placed in other positions as long as they can assist in the movement of the hand-washing device 1A. Also, a movement assistance section may be configured by not installing the horizontal shaft 101 and installing only the running wheels 102A, 102B, which are made up of casters, on the bottom surface of the hand-washing device 1A.

Although not shown, a convex portion may be provided on the bottom surface of the hand-washing device 1A. The convex portion protrudes so as to contact the floor surface when the running wheels 102A and 102B are in contact with the floor surface. This allows the hand-washing device 1 to stand stably and independently.

The hand-washing device 1A further includes an installation position indicator that can turn on the hand-washing device 1A in multiple lighting modes. The hand-washing device 1A acquires information about the intended installation position of the hand-washing device 1A, and the installation position indicator changes the lighting mode depending on whether the hand-washing device 1A has reached the intended installation position.

The "planned installation location of the hand-washing device 1A" here may be the installation location when installing the hand-washing device 1A before installation, or the destination when changing the installation location of the hand-washing device 1A that has already been installed, and refers to an appropriate installation location for the hand-washing device 1A. The information processing device 200A decides the installation location or the destination location. Details will be described later.

For example, the installation position indication unit is configured by the hand-washing indicator 15 of the first embodiment, and when the hand-washing device 1A reaches the intended installation position, the hand-washing indicator 15 lights up blue, and when the hand-washing device 1A has not reached the intended installation position, the hand-washing indicator 15 lights up yellow. This allows the user to know whether the hand-washing device is installed in an appropriate position.

<Overall configuration of information processing system 1000A>
41 is a block diagram showing the overall configuration of an information processing system 1000A. The information processing system 1000A is a system for managing hand-washing devices by collecting and analyzing data such as data on the operating time, installation location, and usage history of the hand-washing devices.

As shown in FIG. 41, the information processing system 1000A includes a hand-washing device 1A, an information processing device 200A, and a terminal device 600 carried by an installer who installed the hand-washing device 1A (such as an administrator of the facility where the hand-washing device 1A is installed). The information processing system 1000A may be configured to include multiple hand-washing devices 1A. The hand-washing device 1A, the information processing device 200A, and the terminal device 600 are connected to each other via a network 500 using a wired or wireless communication standard so that they can communicate with each other.

The hand-washing device 1A is a portable device that can be installed anywhere and allows a user to wash their hands. The hand-washing device 1A is equipped with a communication unit 100A. The communication unit 100A is configured to control communication with the information processing device 200A. Note that, in this embodiment, an example is described in which the hand-washing device 1A is equipped with a movement assistance unit, but the hand-washing device 1A does not need to be equipped with a movement assistance unit as long as it is portable and can be installed anywhere.

After the hand-washing device 1A is installed, the communication unit 100A acquires first information regarding the operating time of the hand-washing device 1A, second information regarding the location where the hand-washing device 1A is installed, and third information regarding the usage history of the hand-washing device 1A. The communication unit 100A also acquires information presented by the information processing device 200A. The communication unit 100A is configured in the same way as the communication unit 100 in FIG. 22, so a description thereof will be omitted.

The information processing device 200A acquires data such as the first information, second information, and third information transmitted from the hand-washing device 1A, and stores the acquired data. The information processing device 200A analyzes the stored data. The information processing device 200A may be composed of one or more devices, and each of the multiple devices may be responsible for a function and perform processing, thereby being recognized as a single information processing device. In addition, the hardware configuration of the information processing device 200A is the same as that of the information processing device 200 in Figure 23, so a description thereof will be omitted.

The terminal device 600 is a device operated by a user who installs and manages each hand-washing device 1A. The terminal device 600 is realized by a mobile terminal such as a smartphone or tablet compatible with a mobile communication system. In addition, the terminal device 600 may be, for example, a stationary PC (Personal Computer) or a laptop PC.

<Overall configuration of information processing device 200A>
Fig. 42 is a block diagram showing the functional configuration of the information processing device 200A. The information processing device 200A is configured in the same manner as the information processing device 200 shown in Fig. 24 except for the proposal generation unit 227, the information presentation unit 228, the installation data (second information) DB 232A, the aggregated data (third information) DB 233A, and the operating time data (first information) DB 242, so the description thereof will be omitted. The proposal generation unit 227, the information presentation unit 228, the installation data DB 232A, the aggregated data DB 233A, and the operating time data DB 242 will be described below.

When the operating time of the hand-washing device 1A reaches a preset time, the proposal generating unit 227 generates a proposal for a change to the number or installation location of the hand-washing devices 1A. For example, the proposal generating unit 227 creates a proposal for a change based on information related to the usage history of the hand-washing device 1A.

Specifically, for example, the proposal generating unit 227 generates a proposal to install an additional hand washing device near a frequently used hand washing device or to move a relatively unused hand washing device near a frequently used hand washing device based on the usage history of the hand washing device 1A for a predetermined period (e.g., once a month) after the hand washing device 1A starts to operate. The proposal generating unit 227 may also generate a proposal to change the installation location of the hand washing device 1A when a period of time during which the hand washing device 1A has started to operate but the frequency of hand washing is relatively low (e.g., the number of times of hand washing within a predetermined period such as one day is less than a certain number) has continued for a certain period or more. The proposal generating unit 227 may also generate a proposal to add a hand washing device 1A based on the usage history of the hand washing device 1A when a period of time during which the hand washing device 1A has started to operate but the frequency of hand washing is relatively low (e.g., the number of times of hand washing within a predetermined period such as one day is more than a certain number) has continued for a certain period or more after the hand washing device 1A starts to operate. This allows the hand washing device 1A to be arranged according to the demand for hand washing.

The information presentation unit 228 presents the first information, second information, and third information acquired from each hand-washing device 1A to the terminal device 600 of each installer who installed each hand-washing device 1A. In addition, the information presentation unit 228 presents the proposal generated by the proposal generation unit 227 to the terminal device 600 of each installer who installed each hand-washing device 1A.

The installation data DB232A is a database for storing data regarding the location where the hand washing device 1A is installed. Details will be described later.

The aggregated data DB233A is a database for storing aggregated data regarding the usage history of the hand washing device 1A. Details will be described later.

The operating time data DB242 is a database for storing information regarding the operating time of the hand-washing device 1A after the hand-washing device 1A is installed. Details will be described later.

<Data structure>
Fig. 43 to Fig. 45 are diagrams showing the data structures of the databases stored in the information processing device 200A. Note that Fig. 25 to Fig. 33 are merely examples, and do not exclude data that is not shown.

Figure 43 is a diagram showing an example of the data structure of installation data DB 232A. As shown in Figure 43, the records of installation data DB 232A are structured in the same way as installation data DB 232 shown in Figure 26, except for the items "facility ID" and "terminal ID", so their explanation is omitted. The items "facility ID" and "terminal ID" are explained below.

The item "Facility ID" stores identification information (ID) for identifying the facility in which the hand-washing device 1A is installed. Each facility is assigned a different ID. The facility ID is used as a key for linking information between other databases. For example, the information processing device 200A extracts various information about one or more hand-washing devices 1A installed in the same facility. Note that the key is not limited to the facility ID, and other information may be used.

The item "Terminal ID" stores identification information (ID) for identifying the terminal device 600 held by the person managing the hand-washing device 1A in a facility where the hand-washing device 1A is installed. Each terminal device 600 is assigned a different ID. For example, the information processing device 200A transmits various information about the hand-washing device 1A to the terminal device 600 corresponding to the hand-washing device 1A and presents it.

Figure 44 is a diagram showing an example of the data structure of aggregated data DB 233A. As shown in Figure 44, the records of aggregated data DB 233A are structured in the same way as aggregated data DB 233 shown in Figure 27, except for the item "facility ID", so a description of these will be omitted. The items "facility ID" and "terminal ID" will be described below.

The item "Facility ID" stores identification information (ID) for identifying the facility in which the hand-washing device 1A is installed. Each facility is assigned a different ID. The facility ID is used as a key for linking information between other databases. For example, the information processing device 200A extracts various information about one or more hand-washing devices 1A installed in the same facility. Note that the key is not limited to the facility ID, and other information may be used.

Figure 45 is a diagram showing an example of the data structure of the operating time data DB 242. As shown in Figure 45, each record of the operating time data DB 242 includes an item "product ID", an item "facility ID", an item "operating time", etc.

The item "Product ID" stores identification information (ID) for identifying the hand-washing device 1A. Each hand-washing device 1 is assigned a different ID. The product ID is used as a key for linking information between other databases. For example, the information processing device 200A extracts various information about each hand-washing device 1A. Note that the key is not limited to the product ID, and other information may be used.

The item "Facility ID" stores identification information (ID) for identifying the facility in which the hand-washing device 1A is installed. Each facility is assigned a different ID. The facility ID is used as a key for linking information between other databases. For example, the information processing device 200A extracts various information about one or more hand-washing devices 1A installed in the same facility. Note that the key is not limited to the facility ID, and other information may be used.

The item "Operating time" stores information regarding the operating time after the hand-washing device 1A has been installed. The information processing device 200A acquires the first information regarding the operating time and manages the hand-washing device 1A as being in operation. For example, the information processing device 200A counts the operating time of the hand-washing device 1A from the time when an instruction to start the operation of the hand-washing device 1A is received from the hand-washing device 1A, and stores the operating time in days. If the information processing device 200A does not receive an instruction to start the operation of the hand-washing device 1A, it stores the hand-washing device 1A as "not operating."

The "instruction to start operation of hand-washing device 1A" referred to here may be, for example, an operation in which the user turns on the switch of hand-washing device 1A after installing it, an operation in which the user inputs information to the effect that operation of hand-washing device 1A has been started via terminal device 600, or an operation in which the user properly sets up hand-washing device 1A, attaches a filter, and starts operation. Note that the operating time of hand-washing device 1A is not necessarily related to the installation date of the hand-washing device. For example, if the user installs hand-washing device 1A but does not turn on the switch, information processing device 200A considers the hand-washing device to be not operating.

This allows the information processing device 200A to accurately determine the operating time of the hand washing device and display this information to the user.

<Operation>
The operation of managing the hand washing device will be described below.
Figure 46 is a diagram illustrating an example of a flow for managing a hand-washing device 1A by an information processing system 1000A according to the fourth embodiment.

In step S2001, before the hand-washing device 1A is installed, the information processing device 200A presents the planned installation location of the hand-washing device to the terminal device associated with the hand-washing device.

Specifically, the information processing device 200A determines the "planned installation location" of the hand-washing device 1A based on information about the facility where the hand-washing device 1A will be installed. For example, if other hand-washing devices are installed in the facility, the information processing device 200A identifies a frequently used hand-washing device based on the usage history of the other hand-washing devices, and determines a location near the frequently used hand-washing device as the "planned installation location" of the hand-washing device to be installed. The information processing device 200A may also accept an operation to specify the "planned installation location" of each hand-washing device 1A in advance by the operator of the facility where the hand-washing device 1A will be installed. The information processing device 200A may also determine the "planned installation location" based on information about the layout of the facility so that the hand-washing devices 1A are spaced apart at a certain interval or more so that they are dispersed. For example, it is assumed that attributes of sections within the facility are determined according to the layout information (e.g., the area occupied by the store, the area used as an aisle, etc.). The information processing device 200A may determine the "planned installation location" of the hand-washing device 1A based on information on the attributes of the sections within the facility. For example, the information processing device 200A may determine to install the hand-washing device 1A at the boundary between the area occupied by the store and the area used as an aisle, or to install the hand-washing device 1A at a position that serves as an entrance or exit of the area used as an aisle. The information processing device 200A may also receive information regarding changes to the layout of the store, and may determine the "planned installation location" of each hand-washing device 1A in response to receiving the information regarding the changes. This allows the information processing device 200A to determine the location where the hand-washing device 1A should be installed in accordance with the information on the changed layout.

In addition, if no other hand-washing devices are installed in the facility, the information processing device 200A determines the "planned installation location" of the hand-washing device 1A to be installed based on information regarding the movement of people in the facility. For example, based on information regarding the number of people entering and exiting each exit of a department store, the information processing device 200A determines a location near an exit with a large number of people entering and exiting as the "planned installation location" of the hand-washing device to be installed.

In addition, if no other hand-washing devices are installed in the facility, the information processing device 200A may determine the "proposed installation location" of the hand-washing device 1A to be installed based on the usage history of hand-washing devices installed in other facilities with similar attributes to the facility. For example, when installing the hand-washing device 1A in a hotel, the information processing device 200A determines a location near the hotel reception desk as the "proposed installation location" of the hand-washing device 1A to be installed based on the usage history of hand-washing devices installed at the reception desk of other hotels that are frequently used.

In step S6001, the terminal device 600 receives the planned installation location of the hand washing device 1A from the information processing device 200A, displays it, and presents it to the user. Details will be explained later in Figure 47.

In step S1001, after the hand-washing device 1A is installed, it acquires and transmits first information regarding the operating time of the hand-washing device 1A, second information regarding the location where the hand-washing device 1A is installed, and third information regarding the usage history of the hand-washing device 1A.

Regarding the first information, the hand-washing device 1A starts acquiring the first information in response to an instruction to start the operation of the hand-washing device 1A. The "instruction to start the operation of the hand-washing device 1A" may be, for example, an operation in which the user turns on the switch of the hand-washing device 1A after installing it, or an operation in which the user inputs information to the effect that the operation of the hand-washing device 1A has started via the terminal device 600, or an operation in which the user properly sets up the hand-washing device 1A, attaches a filter, and starts it to operate. The information processing device 200A manages the hand-washing device 1A as being in operation by acquiring the first information regarding the operating time.

Regarding the second information, the hand-washing device 1A may be equipped with a GPS (Global Positioning System) to detect the location where the hand-washing device 1A is installed. The hand-washing device 1A may also obtain the location where the hand-washing device 1A is installed by receiving an operation from the user to input the installation location of the hand-washing device 1A via the terminal device 600. The hand-washing device 1A may also be installed at the planned installation location by determining that the terminal device 600 is located at the location where the hand-washing device 1A should be installed based on the GPS of the terminal device 600 or identification information of an access point with which the terminal device 600 communicates, etc.

The third information includes at least one of the number of times hand washing is performed at the hand washing device 1A, the amount of water used in hand washing, the amount of chemicals used in hand washing, information regarding dirt, and the time when hand washing was performed, and reflects the frequency of use or load of the hand washing device 1A.

In step S2002, the information processing device 200A acquires the first information, the second information, and the third information from the hand-washing device 1A. The information processing device 200A updates the database stored in the memory unit 230A based on the acquired first information, second information, and third information.

The contents of the database stored in the memory unit 230A are presented to the terminal device 600, for example, in response to a request from the terminal device 600. For example, when the information processing device 200A receives a request from the terminal device 600 to display the first information, the second information, and the third information, the information processing device 200A transmits the first information, the second information, and the third information for each of the multiple hand-washing devices 1A installed in the same facility to the terminal device 600 at a predetermined interval.

For example, the terminal device 600 displays the first information, second information, and third information for each of multiple hand-washing devices 1A installed in the same facility on the same screen. Details will be explained later in Figure 48.

In step S2004, when the operating time of the hand-washing device 1A reaches a preset time, the information processing device 200A presents a proposal for changing the number or installation location of the hand-washing devices 1A.

For example, the information processing device 200A generates a proposal for installing an additional hand washing device near a frequently used hand washing device or for moving a relatively unused hand washing device near a frequently used hand washing device based on the usage history of the hand washing device 1A at predetermined intervals (e.g., one month) after the hand washing device 1A starts operating, and presents the proposal to the terminal device 600.

In step S6002, the terminal device 600 displays a proposal for changing the number or location of hand-washing devices 1A to be installed.

For example, the terminal device 600 displays the installation destination of the hand-washing device 1A to be additionally installed, or the destination of the hand-washing device 1A that has already been installed, determined by the information processing device 200A. Details will be described later in the figure. Details will be described later in FIG. 49.

Through the above series of processes, the information processing device 200A can present information regarding the planned installation location of the hand-washing device 1A to the installer who installed the hand-washing device 1A. The information processing device 200A can also present information regarding the operating time, installation location, and usage history of the hand-washing device 1A to the installer who installed the hand-washing device 1A. The information processing device 200A can also present suggestions for changes to the number or installation locations of the hand-washing devices 1A to the installer who installed the hand-washing device 1A.

As a result, users can grasp the operating status of the hand-washing device 1A, easily manage the hand-washing device, and efficiently consider where to install the hand-washing device.

In addition, because the hand-washing device has a movement assistance unit, the user can easily move the hand-washing device to an appropriate installation position.

Note that in FIG. 46, the operation of managing the hand-washing device 1A is described as a series of operations of the hand-washing device 1A, the information processing device 200A, and the terminal device 600, but is not limited to this. For example, the operation of step S2001 by the information processing device 200A and the operation of step S6001 by the terminal device 600 may be executed independently of FIG. 46. Furthermore, the operation of step S1001 by the hand-washing device 1A and the operation of step S2002 by the information processing device 200A may be executed independently of FIG. 46. Furthermore, the operation of step S2004 by the information processing device 200A and the operation of step S6002 by the terminal device 600 may be executed independently of FIG. 46.

<Display example>
The following describes examples of displays on the terminal device 600. Figures 47 to 49 are diagrams showing examples of screens on the terminal device 600.

The example screen in FIG. 47 shows a situation in which the terminal device 600 displays the intended installation location of the hand-washing device 1A before the hand-washing device 1A is installed. As shown in FIG. 47, a notification is displayed on the display screen of the terminal device 600 to prompt the user to install the hand-washing device 1A in a specified location.

For example, the information processing device 200A determines the exit E1, which has a large number of people entering and exiting, as the "proposed installation location" of the hand-washing device based on information about the number of people entering and exiting each exit of the department store. The terminal device 600 displays a notification to encourage the installation of the hand-washing device 1A at the exit E1.

This allows the user to be informed of the appropriate installation location for the hand-washing device 1A before it is installed. Here, the location of the terminal device 600 held by the installer who will install the hand-washing device 1A (i.e. the location of the installer) may be displayed on the screen shown in the example screen of Figure 47. The screen may also display a route for the installer to travel to the location where the hand-washing device 1A is planned to be installed. This allows the installer to easily move the hand-washing device 1A to the desired installation location, and allows the installation work of the hand-washing device 1A to proceed efficiently.

The example screen in FIG. 48 shows a situation in which the terminal device 600 displays the operating status of multiple hand-washing devices 1A installed in the same facility after the hand-washing device 1A has been installed. As shown in FIG. 48, the first information, second information, and third information of each hand-washing device are displayed on the same screen on the display screen of the terminal device 600. Here, the screen may display hand-washing devices 1A that have already started operating (hand-washing devices 1A whose operating time has been updated in the operating time data 242) separately from hand-washing devices 1A that have not yet started operating (hand-washing devices 1A that are not in the intended installation location or have not been operated to update the operating time). This allows the facility operator to easily check the operating status of the hand-washing devices 1A, such as whether they are operating as planned.

For example, the terminal device 600 displays a map showing the installation locations of each hand-washing device 1A, while also displaying information on the operating time, installation location, and usage history of each hand-washing device 1A on the same screen.

This allows the operating status of multiple hand-washing devices 1A installed in the same facility to be displayed in a manner that is easy for users to see. This allows the user to understand the operating status of the hand-washing devices 1A and easily manage the hand-washing devices 1A.

The example screen in FIG. 49 is a diagram showing a situation in which the terminal device 600 displays a proposal for changing the number or location of hand-washing stations 1A to be installed. As shown in FIG. 49, the display screen of the terminal device 600 displays a proposal to install an additional hand-washing station 1A at a specified location or to move the hand-washing station 1A to a specified location.

For example, if the hand-washing machine 1A installed at exit E1 is frequently used, while the hand-washing machine 1A installed at exit E2 is not used much, the terminal device 600 displays a suggestion to install an additional hand-washing machine 1A at a position near exit E1, or to move the hand-washing machine 1A installed at exit E2 to a position near exit E1.

This allows appropriate suggestions for changing the number of hand-washing devices or the installation locations in the facility where the hand-washing devices are installed, based on the usage history of the hand-washing devices 1A. Therefore, the user can easily manage the hand-washing devices 1A and efficiently consider the installation locations of the hand-washing devices. In addition, in the above example, the hand-washing device 1A is not only transported by human power, but also self-propelled. If the hand-washing device 1A is not in the planned installation location, the information processing device 200A may calculate a route for moving the hand-washing device 1A to the planned installation location, and automatically drive the hand-washing device 1A along the route. This makes it even easier to change the location of the hand-washing device 1A at any time so that it is placed in the optimal location in the facility according to the situation. In addition, when automatically driving the hand-washing device 1A, the information processing device 200A may move the hand-washing device 1A at a time when it is expected that there will be few people staying in the facility, such as outside business hours, based on the business hours of the store in which the hand-washing device 1A is installed.

Fifth embodiment
Next, a fifth embodiment will be described. In the fifth embodiment, a case where the hand washing device 1 uses dedicated water will be described. Note that the same components as those in the first, second, third, and fourth embodiments will be denoted by the same reference numerals and will not be described.

<Overall composition>
50 is a block diagram showing an example of the overall configuration of an information processing system according to embodiment 5. The information processing system 1000B is a system for enabling effective hand-washing using a hand-washing device 1B.

As shown in FIG. 50, the information processing system 1000B includes a hand-washing device 1B, an information processing device 200B, and a terminal device 600. The information processing system 1000B may be configured to include multiple hand-washing devices 1B. The hand-washing device 1B, the information processing device 200B, and the terminal device 600 are connected to a network 500 using a wired or wireless communication standard. The hand-washing device 1B and the information processing device 200B are connected to each other via the network 500 so that they can communicate with each other.

The hand-washing device 1B is a portable device that can be installed anywhere and allows the user to wash their hands. The hand-washing device 1B includes a circulation unit 6B, a chemical tank 50B, a maintenance unit 9B, and a communication unit 100B. Although not shown, the hand-washing device 1B includes a housing 2, a hand-washing basin 11 provided in part of the housing, a faucet 12 that dispenses wash water, a dispenser 14, and the like, as in the first embodiment, to enable hand-washing.

The circulation unit 6B is a unit that purifies and circulates the cleaning water.

The chemical tank 50B is a tank for storing multiple types of chemicals. The chemical tank 50B has, for example, cartridges each filled with a chemical. The chemical tank 50B prepares the chemicals filled in the cartridges based on information about the user of the hand-washing device 1B.

The maintenance unit 9B is a unit that controls the maintenance work for the hand washing device 1B. Similar to the maintenance unit 9 shown in FIG. 12, the maintenance unit 9B includes a first instruction unit 91, a second instruction unit 92, a memory unit 93, and a maintenance control unit 94.

In this embodiment, the maintenance items include, in addition to those described in the second embodiment, for example,
- Refilling the water conditioning tank 700 with liquid or chemicals - Refilling the water storage tank 46 with special water.

The maintenance control unit 94 grasps the remaining amount of liquid in the water storage tank 46 based on, for example, the sensing result of a water level sensor in the water storage tank 46. When the remaining amount is less than a preset amount, the maintenance control unit 94 displays an instruction to refill the water storage tank 46 with dedicated water on the first instruction unit 91 and the second instruction unit 92.
In this embodiment, the dedicated water is a liquid for the hand-washing device 1B, and is a liquid that satisfies predetermined properties. The predetermined properties are, for example, pH, electrical conductivity, redox potential, alkalinity, ion concentration, viscosity, turbidity, color, odor, or hardness. Satisfying predetermined properties means, for example, that pH, electrical conductivity, redox potential, alkalinity, ion concentration, viscosity, turbidity, color, odor, or hardness falls within a predetermined range. Specifically, the dedicated water is, for example, purified water with high purity. The dedicated water may also be an aqueous composition that has a bactericidal effect, a disinfecting effect, an antibacterial effect, a deodorizing effect, or an antifungal effect.

The maintenance control unit 94 also grasps the remaining amount of liquid in the water quality adjustment tank 700 based on, for example, the sensing results of a water level sensor in the water quality adjustment tank 700. If the remaining amount is less than a preset amount, the maintenance control unit 94 displays an instruction on the first instruction unit 91 and the second instruction unit 92 to supply liquid of a preset concentration or a medicine (tablets or concentrated liquid) to the water quality adjustment tank 700.

The maintenance control unit 94 also has, for example, a sensor that detects the remaining amount of drug in the cartridge of the drug tank 50B, and grasps the remaining amount of drug in the cartridge using the sensor. When the remaining amount becomes low, the maintenance control unit 94 displays an instruction to replace the cartridge on the first instruction unit 91 and the second instruction unit 92.

The maintenance control unit 94 determines whether the water refilled into the water tank 46 is proper (genuine). Specifically, for example, the maintenance control unit 94 determines whether the refilled water is proper based on the "sensing result" item of the filter sensing data 933. For example, if the dedicated water is purified water, the predetermined value detected by the sensor units 61 and 62 is different from the value detected when the dedicated water is tap water.

The maintenance unit 9 stores the sensing results detected when the dedicated water is refilled in the memory unit 93 in advance with a predetermined range. When the water is refilled, the maintenance control unit 94 controls, for example, the water discharge unit 20 to discharge cleaning water from the faucet 12. The maintenance control unit 94 determines whether the sensing results detected at this time fall within the preset range.

If the detected sensing results do not fall within a preset range, the maintenance control unit 94 notifies the person refilling that the refilled water is not appropriate. If the results do not fall within the range, the maintenance control unit 94 notifies the person refilling that some of the functions that are performed when the dedicated water is refilled will not be performed. If the results do not fall within the range, the maintenance control unit 94 sends an instruction to, for example, the communication unit 100B to transition from a first mode in which the hand-washing device 1B performs its normal functions to a second mode in which some of the functions are restricted. The preset range of the sensing results may be updated to the latest value when the program is updated.

In this way, by determining whether the refilled water is genuine based on the properties of the water, the hand-washing device 1B can automatically determine whether the water is special purpose water.

The maintenance control unit 94 may also determine whether the refilled water is proper, for example, by reading specific information from a cartridge used to refill the dedicated water. For example, when refilling the dedicated water from a dedicated water cartridge, the dedicated water cartridge and the hand-washing device 1B are physically connected. At that time, an electrical signal is sent from the dedicated water cartridge to the hand-washing device 1B. Upon receiving the signal, the hand-washing device 1B determines that proper dedicated water has been refilled.

The hand-washing device 1B and the dedicated water cartridge may also be provided with a communication device that communicates non-contact (such as near-field wireless communication). When the dedicated water cartridge comes close to the hand-washing device 1B, the hand-washing device 1B reads information from the device provided in the dedicated water cartridge. When the read information meets a predetermined condition, the hand-washing device 1B determines that genuine dedicated water has been refilled.

Alternatively, a specific optical mark may be attached to the dedicated water cartridge, and the hand-washing device 1B may read the optical mark. If the read information satisfies a specific condition, the hand-washing device 1B determines that genuine dedicated water has been refilled.

In this way, by determining whether the refilled water is genuine based on the information assigned to the container for carrying the special water, the hand-washing device 1B is able to determine whether the water is special without performing any special additional processing.

The communication unit 100B is a unit that communicates with the information processing device 200B. The communication unit 100B has a communication unit 110 and a communication control unit 120, similar to the communication unit 100 shown in FIG. 22.

The communication unit 100B acquires first data, which is data related to hand washing, and transmits it to the information processing device 200B. The communication unit 100B also acquires second data, which is data related to maintenance, and transmits it to the information processing device 200B. The communication unit 100B also receives data transmitted from the information processing device 200B.

The communication control unit 120 is configured, for example, so that there is a difference in operation between the first mode and the second mode. In other words, the second mode has limited functionality compared to the first mode. For example, the communication control unit 120 is configured so that some of the data that was transmitted to the information processing device 200B in the first mode is not transmitted in the second mode. In addition, for the hand-washing device 1B operating in the second mode, the data accumulated in the information processing device 200B and the analysis results based on the accumulated data may not be viewable. For example, the hand-washing device 1B operating in the second mode will no longer appear in a display showing how much each hand-washing device is being used, etc.

The information processing device 200B acquires the first data and second data transmitted from the hand-washing device 1B and stores the acquired data. The information processing device 200B also acquires third data related to user information acquired via an application related to the hand-washing device 1B and stores the acquired data. The information processing device 200B transmits information requested by the hand-washing device 1B to the hand-washing device 1B. The information processing device 200B may be composed of multiple devices, each of which performs a specific function, and thus be recognized as a single information processing device. The hardware configuration of the information processing device 200B is the same as that of the information processing device 200 in FIG. 23, and therefore a description thereof will be omitted.

The terminal device 600 is a device carried by a user of the hand-washing device 1B. The terminal device 600 is an example of an item carried by the user, such as a communication device such as a smartphone or a smartwatch.

<Configuration of circulation unit 6B of hand washing device 1B>
Fig. 51 is a block diagram showing a circulation unit 6B of a hand-washing apparatus 1B. As shown in Fig. 51, the circulation unit 6B includes at least a water discharge unit 20, a drainage unit 30, and a purification unit 40B.

The purification unit 40B has the function of purifying the water supplied from the drainage unit 30 in the circulation unit 6B. In addition to the purification unit 40 described in the first embodiment, the purification unit 40B has a water quality adjustment tank 700 and a water quality adjustment pump 701.

The water quality adjustment tank 700 is a tank for storing a liquid for adjusting the property of the water circulated by the circulation unit 6B. When the property of the water circulated by the circulation unit 6B is acidic, the water quality adjustment tank 700 stores, for example, citric acid, tartaric acid, sodium acetate, glycolic acid, lactic acid, and ascorbic acid as an acid agent. The acid agent is generated, for example, by dissolving a tablet in the water supplied to the water quality adjustment tank 700 or by supplying a concentrated liquid. When the property of the water circulated by the circulation unit 6B is alkaline, the water quality adjustment tank 700 stores, for example, ammonia water, ethanolamine, diethanolamine, triethanolamine, 2-amino-2-methyl, morpholine, and sodium hydroxide as an alkaline agent. The alkaline agent is generated, for example, by dissolving a tablet in the water supplied to the water quality adjustment tank 700 or by supplying a concentrated liquid.

A water level sensor is disposed in the water quality adjustment tank 700. The water level sensor detects the water level of the liquid stored in the water quality adjustment tank 700.
The water quality adjustment pump 701 is disposed at the rear of the water quality adjustment tank 700. The water quality adjustment pump 701 is operated under the control of the control unit 60, and adds liquid stored in the water quality adjustment tank 700 to the water that has been post-treated by the post-treatment filter 43.

Specifically, the control unit 60 operates the water quality adjustment pump 701 based on the liquid property detection result by, for example, a pH sensor disposed in the water storage tank 46. For example, when the value of the pH sensor reaches a first value, the control unit 60 operates the water quality adjustment pump 701 to add liquid until the value reaches a second value.

Water that has been post-treated by the post-treatment filter 43 and to which hypochlorous acid water and liquid stored in the water quality adjustment tank 700 have been added flows into the water storage tank 46. The water storage tank 46 stores the water that flows in. For example, a pH sensor is disposed in the water storage tank 46. The pH sensor detects the liquid property of the water stored in the water storage tank 46.

<Configuration of information processing device 200B>
Fig. 52 is a block diagram showing the functional configuration of the information processing device 200B. As shown in Fig. 52, the information processing device 200B includes a communication unit 210, a control unit 220B, and a storage unit 230B.

The control unit 220B functions as a reception control unit 221, a transmission control unit 222, and a decision unit 229 by the processor of the information processing device 200B performing processing according to a program.

The determination unit 229 determines the appropriate drug combination for the user based on the collected data.

The storage unit 230B stores data and programs used by the information processing device 200B. The data used by the information processing device 200B is, for example, similar to the data used by the information processing device 200 of the third embodiment.

The memory unit 230B stores product data DB 231B, installation data DB 232, aggregated data DB 233B, hand-washing data DB 234B, sterilization device usage data DB 235, user data DB 236B, maintenance DB 237, environmental data DB 238, monitoring data DB 239, analysis results DB 240, model DB 241, water composition data DB 243, and drug composition data DB 244, etc.

The water composition data DB243 is a database for holding data regarding the composition of the water used in the hand washing device 1B.

The drug composition data DB244 is a database for holding data regarding the composition of the drug used in the hand washing device 1B.

The memory unit 230B may be a single memory device, or may be realized by multiple memory devices that store at least one database.

<Operation>
<Certification of dedicated water>
Next, the operation of the maintenance unit 9B in this embodiment will be described with reference to Figures 59 and 60. Figure 59 is a flow chart showing an example of the operation when the maintenance unit 9B authenticates whether or not the refilled water is genuine.

First, the water storage tank 46 of the hand-washing device 1B is refilled with dedicated water. When the water storage tank 46 is refilled with water, the maintenance control unit 94 detects the properties of the refilled water in step S171 using the sensor units 61 and 62. Specifically, for example, when water is refilled, the maintenance control unit 94 controls the water discharge unit 20 to discharge wash water from the faucet 12. The maintenance control unit 94 detects the properties of the water circulated at this time using the sensor units 61 and 62.

In step S172, the maintenance control unit 94 determines whether the detected sensing result falls within a preset range. That is, the maintenance control unit 94 determines whether the refilled water is dedicated water. Specifically, the memory unit 93 pre-stores, with a predetermined range, the sensing result detected when the dedicated water is refilled. The maintenance control unit 94 determines whether the detected value falls within the pre-stored range.
If the detected value falls within the pre-stored range (Yes in step S172), the maintenance control unit 94 operates the hand-washing device 1B in the first mode in step S173.
On the other hand, if the detected value does not fall within the pre-stored range (No in step S172), the maintenance control unit 94 operates the hand-washing device 1B in the second mode in step S174.

Figure 60 is a flowchart showing another example of the operation of the maintenance unit 9B when authenticating whether the refilled water is genuine or not.

In step S181, when the water tank 46 is refilled with water, the maintenance control unit 94 reads information assigned to a container for carrying special water. Specifically, for example, the hand-washing device 1B is equipped with a reading device capable of reading information without contact. Also, the container is equipped with a storage device that holds information in a format that can be read by the reading device. When water is refilled, the maintenance control unit 94 uses the reading device to read information from the storage device attached to the container.

In step S182, the maintenance control unit 94 determines whether the read information satisfies a predetermined condition. That is, the maintenance control unit 94 determines whether the refilled water is dedicated water. Specifically, the memory unit 93 pre-stores code information indicating that the water is dedicated water. The maintenance control unit 94 determines whether the read information matches the pre-stored code information.

<Drug customization>
Next, the operation of the hand-washing device 1B in this embodiment will be described with reference to Fig. 61. Fig. 61 is a flow chart showing an example of the operation of the hand-washing device 1B when customizing and discharging medicine.

First, a user who uses the hand-washing device 1B inserts, for example, a smartphone, which is a user's personal item, into the UV sterilization device 80. In step S191, the communication control unit 120 acquires specific information from the smartphone. The specific information includes, for example, a user ID for identifying the user. The communication control unit 120 transmits the acquired user ID to the information processing device 200B.

In step S192, the information processing device 200B determines the combination of medicines to be ejected based on the received user ID. Specifically, when the control unit 220B receives the user ID, it reads out the hand-washing data DB 234B, the user data DB 236B, or the medicine composition data DB 244 from the memory unit 230B based on the received user ID. The control unit 220B determines the combination of medicines suitable for the user identified by the user ID based on the hand-washing data DB 234B, the user data DB 236B, or the medicine composition data DB 244 that it reads out. For example, the control unit 220B takes into account the quality of past stains, medicines used in the past, etc., and determines the combination of medicines suitable for the user. The control unit 220B transmits information regarding the combination of medicines to the hand-washing device 1B.

In step S193, the hand-washing device 1B has the user wash their hands. Specifically, the hand-washing device 1B discharges wash water from the faucet 12 in response to the user's actions. The hand-washing device 1B also mixes a chemical agent with a determined mixture in response to the user's actions. After mixing the chemical agent, the hand-washing device 1B discharges the compounded chemical agent from the dispenser 14. The user, for example, wets their hands with the wash water discharged from the faucet 12, and washes their hands with the chemical agent discharged from the dispenser 14. The user then rinses their chemically-contaminated hands with the wash water discharged from the faucet 12.

In step S194, the communication control unit 120 transmits the data acquired from hand washing to the information processing device 200B.

In step S195, the control unit 220B updates the database stored in the memory unit 230B based on the received data.

As described above, in this embodiment, dedicated water that meets certain properties is used as the cleaning water. This makes it possible to reduce the components that precipitate in the water, and makes it possible to reduce the frequency of replacing filters, etc.

Therefore, the hand washing device 1B of this embodiment can reduce the maintenance burden.

Furthermore, in this embodiment, the hand-washing device 1B has a means for detecting that the dedicated water is being used. At this time, the hand-washing device 1B uses the sensor units 61, 62 as a means for detecting that the dedicated water is being used. Furthermore, the hand-washing device 1B uses a device that reads out predetermined information from a container for transporting the dedicated water as a means for detecting that the dedicated water is being used. This makes it possible for the hand-washing device 1B to detect that the dedicated water has been refilled without performing any special additional processing.

In addition, in this embodiment, it is determined whether the refilled water is dedicated water or not based on the detection result by the detection means. This allows the hand-washing device 1B to automatically determine whether dedicated water has been refilled. This makes it possible to create an environment in which dedicated water can be used without any burden.

In addition, in this embodiment, if the hand-washing device 1B determines that the refilled water is dedicated water, it operates in a first mode, and if it determines that the refilled water is not dedicated water, it operates in a second mode with more limited functionality than the first mode. If water other than the recommended dedicated water is refilled, there is a possibility that the accuracy of the sensing results sent from the hand-washing device 1B to the information processing device 200B will vary. This may affect the accuracy of data analysis in the information processing device 200B. By restricting the uploading of data from hand-washing devices 1B that have not been refilled with dedicated water, it is possible to maintain the accuracy of data analysis in the information processing device 200B.

Furthermore, since data analysis based on hand-washing data is no longer possible for hand-washing device 1B operating in the second mode, hand-washing device 1B operating in the second mode will no longer be able to receive feedback based on hand-washing at its own device. Furthermore, hand-washing device 1B operating in the second mode will no longer be the subject of analysis performed by information processing device 200B. As a result, hand-washing device 1B will no longer be included in an overall display of which hand-washing devices are being used and how much. In other words, if hand-washing device 1B is not operated using dedicated water, it will not be able to perform its original functions. This can be an incentive to operate hand-washing device 1B using dedicated water.

In addition, in this embodiment, the circulation unit 6B has a water quality adjustment tank 700 for adding chemicals to adjust the quality of the water stored in the water storage tank 46, and a water quality adjustment pump 701. This makes it possible to adjust the quality of the wash water to a quality suitable for hand washing. Because the hand washing device 1B is installed in various locations, the dirt to be washed may also differ depending on the location. If it becomes possible to adjust the quality of the wash water for each hand washing device 1B, it becomes possible to appropriately wash hand dirt specific to the location where it is installed, improving hygiene.

Note that in FIG. 61, an example has been described in which the communication control unit 120 acquires a user ID from the terminal device 600 carried by the user and transmits the acquired user ID to the information processing device 200B. However, the user ID may also be transmitted from the terminal device 600 to the information processing device 200B.

Specifically, for example, when a user uses the hand-washing device 1B, the user operates the terminal device 600 and launches an application related to the hand-washing device 1B. The user transmits, via the application, to the information processing device 200B, a message indicating that the user is about to use the hand-washing device 1B, together with the user ID. The information processing device 200B determines the combination of medicines to be ejected based on the received user ID.

The application related to the hand-washing device 1B may be a dedicated application for the hand-washing device 1B, or may be an application for the store, facility, etc. in which the hand-washing device 1B is installed. If the application related to the hand-washing device 1B is an application for a store, facility, etc., a user who washes their hands using the hand-washing device 1B may be provided with information useful for activities within the store or facility via this application.

Also, FIG. 61 describes a case where the combination of medicines is determined by the information processing device 200B based on information transmitted from the hand-washing device 1B. However, the hand-washing device 1B may determine the combination of medicines based on specifications input by the user. For example, when the combination of medicines is specified by the user, the hand-washing device 1B ejects medicine prepared with the specified combination in step S193.

<Modification>
Next, a hand-washing device 1B according to a modified example will be described. In this modified example, the hand-washing device 1B has a function of providing a user with a chemical agent that has an additional effect after washing their hands.

<Configuration of circulation unit 6B of hand washing device 1B>
Fig. 62 is a block diagram showing a circulation unit 6B of a hand-washing apparatus 1B according to a modified example of embodiment 5. As shown in Fig. 62, the circulation unit 6B includes at least a water discharge unit 20B, a drainage unit 30, and a purification unit 40B.

The water discharge unit 20B has the function of discharging water purified by the purification unit 40B from the water outlet 13 of the faucet 12 in the circulation unit 6B.

The water discharge unit 20B mainly comprises a water discharge pump 21, a UV sterilization section 22, an infrared sensor 23, an additional chemical tank 702, and a delivery pump 703.

The additional chemical tank 702 is a tank for storing a chemical that is expected to have a specific additional effect on hands after washing. The additional chemical tank 702 has, for example, multiple cartridges each filled with a chemical containing a specific ingredient. The specific ingredient is, for example, hyaluronic acid with a moisturizing effect, squalane with a moisturizing effect, lavender oil with a relaxing effect, peppermint oil with a germicidal effect, or fragrance for adding a scent. When the additional chemical tank 702 receives a specification regarding the composition of the chemical, it has the function of compounding the chemicals filled in the cartridges with the specified composition.

The delivery pump 703 is disposed downstream of the additional chemical tank 702. The delivery pump 703 is operated under the control of the control unit 60, and adds the chemical compounded in the additional chemical tank 702 to the water after UV sterilization.

Specifically, when an object is detected by infrared sensor 23 under conditions that satisfy predetermined conditions, control unit 60 operates delivery pump 703 and water discharge pump 21. For example, assume that an infrared sensor other than infrared sensor 23 is installed in hand-washing device 1B. When infrared sensor 23 detects an object within a predetermined period of time after this infrared sensor detects an object, control unit 60 operates delivery pump 703 and water discharge pump 21.

Also, for example, if an object is detected by the infrared sensor 23 after the hand-washing indicator 15 has finished displaying the hand-washing time without the user being replaced, the control unit 60 may operate the delivery pump 703 and the water discharge pump 21.

<Configuration of information processing device 200B>
Fig. 63 is a block diagram showing the functional configuration of an information processing device 200B according to a modified example. As shown in Fig. 63, the information processing device 200B includes a communication unit 210, a control unit 220B, and a storage unit 230B.

<Operation>
<Customization of additional drugs>
Next, the operation of the hand-washing device 1B in this embodiment will be described with reference to Fig. 69. Fig. 69 is a diagram for explaining an example of the operation of the hand-washing device 1B and the information processing device 200B when the hand-washing device 1B customizes and ejects the additional medicine.

The communication control unit 120 acquires predetermined information from the user's carried items, for example, by processing similar to step S191 shown in FIG. 61. The predetermined information is, for example, a user ID for identifying the user. The communication control unit 120 transmits the acquired user ID to the information processing device 200B.

In step S1101, the information processing device 200B determines the combination of the medicine to be ejected and the additional medicine based on the received user ID. Specifically, when the control unit 220B receives the user ID, it reads out the hand-washing data DB 234B, the user data DB 236B, the medicine composition data DB 244, or the additional medicine composition data DB 245 from the memory unit 230B based on the received user ID. The control unit 220B determines the combination of medicine suitable for the user identified by the user ID based on the hand-washing data DB 234B, the user data DB 236B, or the medicine composition data DB 244 that it reads out.

The control unit 220B also determines the combination of additional drugs suitable for the user identified by the user ID based on the hand-washing data DB 234B, user data DB 236B, drug composition data DB 244, or additional drug composition data DB 245 that have been read. For example, the control unit 220B determines the combination of drugs suitable for the user by taking into consideration the user's preferences, the user's condition, and additional drugs used in the past. The user's preferences include, for example, the user's favorite scent and the user's desired effect. The user's condition includes the user's skin condition, any allergies the user has, the user's medication information, and the like. The control unit 220B transmits information regarding the combination of drugs and information regarding the combination of additional drugs to the hand-washing device 1B.

In step S1102, the hand-washing device 1B has the user wash their hands. Specifically, the hand-washing device 1B discharges wash water from the faucet 12 in response to the user's actions. The hand-washing device 1B also mixes a chemical agent with a determined mixture in response to the user's actions. After mixing the chemical agent, the hand-washing device 1B discharges the compounded chemical agent from the dispenser 14. The user, for example, wets their hands with the wash water discharged from the faucet 12, and washes their hands with the chemical agent discharged from the dispenser 14. The user then rinses their chemically-contaminated hands with the wash water discharged from the faucet 12.

The hand-washing device 1B prepares the additional chemical in a determined combination according to the actions of the user after washing their hands. Once the hand-washing device 1B prepares the additional chemical, it operates the discharge pump 21 and causes water in the water storage tank 46 to be discharged from the faucet 12. The hand-washing device 1B operates the delivery pump 703 in conjunction with the discharge pump 21, and adds the additional chemical to the cleaning water discharged from the faucet 12. The user applies the cleaning liquid with the added additional chemical to their hands to enjoy the added effect.

In step S1103, the communication control unit 120 transmits the data acquired from hand washing to the information processing device 200B.

In step S1104, the control unit 220B updates the database stored in the memory unit 230B based on the received data.

As described above, in the modified version of the fifth embodiment, the hand-washing device 1B has a delivery means (additional agent tank 702, delivery pump 703) for delivering an agent with an additional effect. This allows the hand-washing device 1B to provide the user with an agent with an additional effect in addition to washing their hands.

In addition, in this modified example, the hand-washing device 1B adds a chemical with an additional effect to the washing water discharged from the faucet 12 and provides it to the user. This allows the user to use the chemical with an additional effect as a continuation of hand-washing.

In addition, in this modified example, the additional effect is due to at least one of the moisturizing ingredients, aromatic ingredients, and medicinal ingredients contained in the medicine. This allows the user to pay attention to skin care after washing their hands. Furthermore, if the hand-washing device 1B is installed in a store, the aromatic ingredients can be scented with a scent specific to the store, or a scent recommended by the store. By applying a scent specific to the store or a scent recommended by the store to the hands after washing the hands, it becomes possible to enjoy the scent of the hands when entering the store. Furthermore, the scent that remains on the hands of a user who has entered the store also has an advertising effect on others.

In addition, in this modified example, the additional agent tank 702 has the function of compounding an agent in a specified mixture. This allows the hand-washing device 1B to provide an agent with any additional effect.

In addition, in this modified example, the drug combination is determined based on information about the user. The information about the user is information about the user's condition or information about the user's preferences. This allows the user to enjoy the additional effects that they desire. Furthermore, the user is automatically provided with a drug that has an additional effect that is suitable for them.

Note that in FIG. 69, an example is described in which the communication control unit 120 acquires specific information from the terminal device 600 carried by the user and transmits the acquired information to the information processing device 200B, but the specific information may also be transmitted from the terminal device 600 to the information processing device 200B.

Figure 70 is a diagram illustrating an example of the operation of the hand-washing device 1B, the terminal device 600, and the information processing device 200B when specific information is transmitted from the terminal device 600 to the information processing device 200B.

For example, in step S1111, the user operates the terminal device 600 to log in to a user page in which the user has registered for a provided service. Specifically, when the user uses the hand-washing device 1B, the user launches an application associated with the service. The user enters a password or the like from the login screen of the launched application and logs in to the page. The service is provided, for example, by the hand-washing device 1B, a store in which the hand-washing device 1B is installed, or a facility in which a store is located.

Fig. 71 is a schematic diagram showing an example of a user page displayed on the display 610 of the terminal device 600. On the user page shown in Fig. 71, a field object 611 and operation objects 612 to 617 are displayed.
The field object 611 is an object that represents, for example, an outline of a service.
The operation objects 612 to 617 are objects for receiving instructions from the user. When the operation object 612 to 617 is selected by the user, the terminal device 600 transitions the display on the display 610 to a screen corresponding to the operation object 612 to 617.

The operation object 615 is an object that is selected when using the hand-washing device 1B. When the user selects the operation object 615, the terminal device 600 transitions the display on the display 610 to a screen related to the use of the hand-washing device 1B.

Figures 72 and 73 are schematic diagrams showing examples of screens related to the use of the hand-washing device 1B. The screens shown in Figures 72 and 73 display, for example, a screen for inputting the user's preferences or the user's condition. The user selects, for example, one of the options displayed. When the user has completed the selection, the user presses the operation object 618. The operation object 618 is an object for confirming the selection and transmitting the selection to the information processing device 200B. When the operation object 618 is pressed by the user, the terminal device 600 transmits the user ID, information related to the user's preferences, or information related to the user's condition to the information processing device 200B.

In step S1112, the information processing device 200B determines the combination of the medicine to be ejected and the additional medicine based on the received information. Specifically, when the control unit 220B receives the user ID, it reads out the hand-washing data DB 234B, the user data DB 236B, the medicine composition data DB 244, or the additional medicine composition data DB 245 from the memory unit 230B based on the received user ID. The control unit 220B determines the combination of medicine suitable for the user identified by the user ID based on the hand-washing data DB 234B, the user data DB 236B, or the medicine composition data DB 244 that it reads out.

The control unit 220B also determines the combination of additional drugs suitable for the user identified by the user ID based on the read hand-washing data DB 234B, user data DB 236B, drug composition data DB 244, additional drug composition data DB 245, or received information (information on the user's preferences and information on the user's condition). For example, the control unit 220B takes into consideration the received information and additional drugs used for past preferences and conditions, etc., to determine the combination of drugs suitable for the user. The control unit 220B transmits information on the combination of drugs and information on the combination of additional drugs to the hand-washing device 1B.

In step S1102, the hand-washing device 1B prompts the user to wash his or her hands, similar to that shown in FIG.
In step S1103, the hand-washing device 1B transmits data acquired during hand-washing to the information processing device 200B.
In step S1104, control unit 220B updates the database stored in storage unit 230B based on the received data.

In step S1113, the control unit 220B provides the user who washed their hands using the hand-washing device 1B with information that is useful for activities within the store or facility. Information that is useful for activities is, for example, information about various benefits, such as coupons or points.

Fig. 74 is a schematic diagram showing an example of a screen displaying valid information provided by information processing device 200B. The screen shown in Fig. 74 displays that one store visit point has been awarded for washing hands with hand-washing device 1B.
In addition, the valid information is not limited to information provided from the information processing device 200B, but may be provided from the hand-washing device 1B through direct communication with the hand-washing device 1B.

Also, in Figures 69 and 70, a case has been described in which information acquired when washing hands is transmitted from the hand washing device 1B to the information processing device 200B in step S1103. In this embodiment, the user may input thoughts about hand washing, etc., to the terminal device 600 as information acquired when washing hands. The terminal device 600 transmits information such as thoughts about hand washing to the information processing device 200B as information acquired when washing hands. A predetermined incentive may be given by the information processing device 200B to the terminal device 600 that transmitted the thoughts, etc.

Also, in Figures 69 and 70, a case has been described in which the blend of additional medicines is determined by the information processing device 200B based on information about the user. In this embodiment, the determination of the blend of additional medicines does not have to be based on information about the user. For example, the control unit 220B may determine the blend of additional medicines based on the environment in which the hand-washing device 1B is installed. Specifically, for example, the communication control unit 120 acquires environmental information such as atmospheric pressure, temperature, and humidity of the location in which the hand-washing device 1B is installed at a predetermined interval. The communication control unit 120 transmits the acquired environmental information and the device ID to the information processing device 200B.

When the control unit 220B receives the device ID and environmental information, it reads out the hand-washing data DB 234B, the environmental data DB 238, the drug composition data DB 244, or the additional drug composition data DB 245 from the memory unit 230B based on the received device ID and environmental information. The control unit 220B determines the drug composition suitable for the current environment based on the hand-washing data DB 234B, the environmental data DB 238, the drug composition data DB 244, or the additional drug composition data DB 245 that it has read out.

In a modified example of this embodiment, the case where the chemical stored in the additional chemical tank 702 is added to the flushing water discharged from the faucet 12 has been described as an example. In a modified example of this embodiment, the additional chemical may not be added to the flushing water, but may be discharged from a different discharge port.

Figure 75 is a block diagram showing another example of the circulation unit 6B of the hand-washing apparatus 1B according to a modified example of the fifth embodiment. The circulation unit 6B shown in Figure 75 has, for example, an additional medicine tank 702, a delivery pump 703, and an infrared sensor 704. The control unit 60 causes the additional medicine tank 702 to mix medicine in response to detection of a hand by the infrared sensor 704. The mixture of medicine is determined, for example, by the information processing device 200B or the hand-washing apparatus 1B as described above. When the control unit 60 mixes the medicine, it operates the delivery pump 703. The delivery pump 703 delivers the medicine mixed in the additional medicine tank 702 to the outlet.

In this way, by ejecting a medicine with an additional effect from the ejection port, it is possible to provide the medicine separately from hand washing. This improves the convenience of the hand washing device 1B.

Although several embodiments of the present disclosure have been described above, these embodiments can be implemented in various other forms, and various omissions, substitutions, and modifications can be made without departing from the spirit of the invention. These embodiments and their modifications are considered to be within the scope of the invention and its equivalents as set forth in the claims, as well as within the scope and spirit of the invention.
