The hand-washing device 1, the monitoring device 300, the terminal device 10A, the terminal device 10B, and the server 200 are connected to each other so as to be able to communicate with each other via a network 800 using a wired or wireless communication standard. Note that, in this embodiment, a case in which the system 1000 includes the monitoring device 300 is described as an example, but the system 1000 does not necessarily have to include the monitoring device 300.

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 can be installed in various locations, such as indoors and outdoors. The hand-washing device 1 is installed indoors, for example, near the entrance of a building, in the office space of a business operator occupying the building, near the entrance of a store, etc. For example, if the building is a facility for accommodation, exercise, entertainment, etc. and check-in is required to use the facility, the hand-washing device 1 is installed at a location where check-in takes place. For example, it is assumed that a user will wash their hands with the hand-washing device 1 before or after filling out certain details with a shared writing instrument to check in. The hand-washing device 1 may also be installed near the entrance of a facility that provides a certain service, for example, a facility that provides food and drink or transportation services.

The hand-washing device 1 includes a communication unit 400. The communication unit 400 is a unit that allows the hand-washing device 1 to communicate with an external device such as the server 200. The communication unit 400 acquires data related to the usage history of the hand-washing device 1 and transmits it to the server 200. For example, the hand-washing device 1 stores information related to operations such as water discharge, drug ejection, and water discharge, recognizes a series of operations of water discharge, drug ejection, and water discharge that are close in time as one hand-washing session, and acquires information related to the usage history of the hand-washing device 1. Also, for example, the hand-washing device 1 stores information related to operations when sterilizing portable items, and acquires information related to the usage history of the hand-washing device 1.

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.

Alternatively, the hypochlorous acid water may be generated by dissolving salt in the water supplied to the chlorine tank 67 and electrolyzing the salt water.
In addition, an electrolysis unit that performs electrolysis on saline water to generate hypochlorous acid water may be provided separately downstream of the chlorine tank 67.

A water level sensor is disposed in the chlorine tank 67. The water level sensor detects the water level of the hypochlorous acid water stored in the chlorine tank 67.
The chlorine pump 68 is disposed downstream of the chlorine tank 67. The chlorine pump 68 is operated under the control of the control unit 60, and adds hypochlorous acid water stored in the chlorine tank 67 to the water that has been post-treated by the post-treatment filter 43.

Inside the housing 2, a drug tank 50 and a drug pump 51 are provided.

The chemical pump 51 is disposed downstream of the chemical tank 50. The chemical pump 51 is operated under the control of the control unit 60, and delivers the chemical (e.g., soapy water) stored in the chemical tank 50 to the nozzle of the dispenser 14.

Specifically, the control unit 60 operates the drug pump 51 in response to detection of an object by the infrared sensor 52 of the dispenser 14. For example, the control unit 60 operates the drug pump 51 while an object is detected by the infrared sensor 52. The control unit 60 stops the drug pump 51 when an object is no longer detected by the infrared sensor 52.

The drug tank 50 is a tank for storing drug. A water level sensor is disposed in the drug tank 50. The water level sensor detects the water level of the drug stored in the drug tank 50. When the water level of the drug falls below a predetermined value, the drug is replenished.

(Configuration of external module 7)
FIG. 5 is a front view of the external module 7 shown in FIG.
As shown in FIG. 5 , the external module 7 includes a pre-treatment filter 41 , a post-treatment filter 43 , and a UV sterilization device 80 .

The pre-processing filter 41 and the post-processing filter 43 are arranged side by side outside the housing 2. More specifically, the pre-processing filter 41 and the post-processing filter 43 are arranged side by side in the horizontal direction outside the housing 2.

The attachment portion 82 of the pre-treatment filter 41 and the attachment portion 83 of the post-treatment filter 43 are integrally formed with the UV sterilization device 80. The UV sterilization device 80 is connected above the attachment portions 82 and 83.
The pre-processing filter 41 is removably attached to the attachment portion 82. The post-processing filter 43 is removably attached to the attachment portion 83.

The pre-treatment filter 41 and the post-treatment filter 43 are housed in a container that is permeable and the inside of which is visible, so that the pre-treatment of the water in the pre-treatment filter 41 and the post-treatment of the water in the post-treatment filter 43 can be visually observed from the outside.
The muddy water can be visually confirmed in the pre-treatment by the pre-treatment filter 41. Also, the purified water can be visually confirmed in the post-treatment by the post-treatment filter 43.

(Configuration of UV sterilization device 80)
The UV sterilization device 80 (sterilization device) has a function of irradiating ultraviolet rays to the user's belongings and sterilizing the surfaces of the belongings. Examples of the user's belongings include (1) items worn on the user's body, such as glasses and wristwatches, (2) items held by the user in the hand and used for other items or devices, such as keys and cards (e.g., keys used to lock or unlock doors, cards with built-in communication chips for communicating with payment devices, etc.), and (3) devices operated by the user in the hand, such as smartphones.
In this embodiment, a smartphone carried by a user is taken as an example of the portable item. The UV sterilization device 80 is provided outside the housing 2 as a part of the external module 7.

As shown in FIG. 3A , the UV sterilization device 80 is disposed on a side surface of the housing 2 .
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 7 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. 7A, 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. 7B, 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. 7C, 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.

(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. 8 is a diagram for explaining the display mode of the hand-washing indicator 15. Fig. 9 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. 8A. 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. 8B, 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. 8C (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. 8D, 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 sterilization indicator 16. Fig. 10 is a diagram for explaining the display mode of the sterilization indicator 16. Fig. 11 is an explanatory diagram showing the control process of the sterilization indicator 16.

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. 11).

As shown in Fig. 10A, 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. 10B. 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. 10D. 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. 3B 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 specialized transportation staff to move the housing 2. For example, the housing 2 is installed near the entrance of a store, and customers are asked to 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 customers with an environment where they can 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 user to be informed of the progress of the sterilization process. This ensures convenience for the user.

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.

<1.2 Configuration of terminal device 10A>
Fig. 12 is a block diagram of a terminal device 10A operated by a user using the hand washing device 1. As shown in Fig. 12, the terminal device 10A includes a communication unit 120, an operation reception unit 130 (including a touch-sensitive device 131 and a display 132), a voice processing unit 140, a microphone 141, a speaker 142, a position information sensor 150, a camera 160, a storage unit 170A, and a control unit 180A. The terminal device 10A also has functions and configurations (e.g., a battery for storing power, a power supply circuit for controlling the supply of power from the battery to each circuit, etc.) that are not particularly shown in Fig. 12. As shown in Fig. 12, each block included in the terminal device 10A is electrically connected by a bus or the like.

The communication unit 120 performs processing for the terminal device 10A to communicate with an external device using a wired or wireless communication standard. For example, an optical code associated with the hand-washing device 1 is attached to the hand-washing device 1. The optical code includes, for example, information that allows access to the hand-washing device 1, such as a URL. The optical code is, for example, a two-dimensional code such as a QR code (registered trademark). When the optical code is read by the terminal device 10A through a user's operation, the communication unit 120 communicates with the hand-washing device 1, the server 200, or both of them based on the information included in the read optical code. The communication unit 120 may also communicate with the hand-washing device 1 through short-range wireless communication. For example, both the hand-washing device 1 and the terminal device 10A are compatible with a short-range wireless communication standard. The user establishes communication with the hand-washing device 1 by bringing the terminal device 10A close to the hand-washing device 1.

The operation reception unit 130 has a mechanism for receiving input operations from an operator. Specifically, the operation reception unit 130 is configured as a touch screen, and includes a touch-sensitive device 131 and a display 132. The operation reception unit 130 may also include a mouse, a keyboard, etc.

The touch-sensitive device 131 accepts input operations by the operator of the terminal device 10A. The touch-sensitive device 131 detects the operator's touch position on the touch panel, for example, by using a capacitive touch panel. The touch-sensitive device 131 outputs a signal indicating the operator's touch position detected by the touch panel to the control unit 180A as an input operation.

The display 132 displays data such as images, videos, and text in response to the control of the control unit 180A. The display 132 is realized, for example, by an LCD (Liquid Crystal Display) or an organic EL (Electro-Luminescence) display.

The audio processing unit 140, for example, performs digital-to-analog conversion of the audio signal. The audio processing unit 140 converts the signal provided by the microphone 141 into a digital signal and provides the converted signal to the control unit 180A. The audio processing unit 140 also provides the audio signal to the speaker 142. The audio processing unit 140 is realized, for example, by a processor for audio processing. The microphone 141 accepts audio input and provides an audio signal corresponding to the audio input to the audio processing unit 140. The speaker 142 converts the audio signal provided by the audio processing unit 140 into audio and outputs the audio to the outside of the terminal device 10A.

The position information sensor 150 is a sensor that detects the position of the terminal device 10A, and is, for example, a GPS (Global Positioning System) module. The GPS module is a receiving device used in a satellite positioning system. In a satellite positioning system, signals are received from at least three or four satellites, and the current position of the terminal device 10A in which the GPS module is installed is detected based on the received signals.

Camera 160 is a device that receives light using a light receiving element and outputs the light as a captured image. Camera 160 is, for example, a depth camera that can detect the distance from camera 160 to the subject being photographed.

The memory unit 170A is realized, for example, by the storage 164, and stores data and programs used by the terminal device 10A. In one aspect, the memory unit 170A stores user information 171.

User information 171 is information about a user who has used the hand-washing device 1. For example, user information 171 includes information for identifying the user, the user's name, gender, and information about the history of granting specific effects to the user.

The control unit 180A reads the program stored in the storage unit 170A and executes the instructions contained in the program to control the operation of the terminal device 10A. By operating according to the program, the control unit 180A fulfills the functions of an input operation reception unit 181, a transmission/reception unit 182A, and a display control unit 183A.

The input operation reception unit 181 performs processing to receive input operations by an operator on an input device such as the touch-sensitive device 131.

The transmission/reception unit 182A performs processing for the terminal device 10A to transmit and receive data to and from an external device such as the server 200 in accordance with a communication protocol. For example, the transmission/reception unit 182A transmits user information to the server 200 via the communication unit 120. Also, for example, the transmission/reception unit 182A receives information relating to a specific effect given to the user from the server 200 via the communication unit 120. The received information relating to the specific effect is stored in the user information 171.

The display control unit 183A controls the display 132 to display information related to the specific effect given to the user. Furthermore, for example, if the hand-washing device 1 is equipped with a reading unit (such as an optical scanner) that reads optical codes, the display control unit 183A may cause the display 132 to display an optical code including user information. For example, before using the hand-washing device 1, the user causes the display 132 to display an optical code and causes the reading unit installed in the hand-washing device 1 to read the optical code. This causes the hand-washing device 1 to store the fact that the user has used the hand-washing device 1.

For example, the granting unit 2034 grants the user an advantageous effect when using a facility in which the hand-washing device 1 is installed, at the time when the user finishes using the hand-washing device 1. Note that the granting unit 2034 may grant the specific effect at other times.

The specific effect may be, for example, a discount right that can be used at the facility, or a valuable value. For example, the specific effect may be something that can be used at the facility, such as a discount coupon, points, or virtual currency. Note that the specific effect is not limited to the above, and may be anything that is beneficial to the user.

The granting unit 2034 may specify the content of the effect based on the usage history of the hand-washing device 1 and a preset granting rule to grant to the user. The granting rule may be presented to visitors to the facility. For example, the granting unit 2034 specifies the type and quantity of the effect to be granted to the user based on the history of the user washing his/her hands using the hand-washing device 1 or the history of the user sterilizing his/her portable items using the UV sterilization device 80 of the hand-washing device 1. For example, the granting unit 2034 grants a predetermined number of discount coupons to a user who washed his/her hands using the hand-washing device 1. The granting unit 2034 grants a predetermined number of points to a user who sterilized his/her portable items using the UV sterilization device 80 of the hand-washing device 1. The granting unit 2034 grants a predetermined number of discount coupons and a predetermined number of points to a user who both washed his/her hands and sterilized his/her portable items. The granting unit 2034 may grant a predetermined effect only to a user who both washed his/her hands and sterilized his/her portable items.

In addition, the discount right or valuable value granted to the user as a specific effect may have an expiration date. For example, the specific effect may be a discount coupon that can be used at a facility, and the discount coupon can only be used within a specified period from the date of grant. When granting the discount right or valuable value to the user, the granting unit 2034 presents information regarding the expiration date to the user. In addition, the expiration date may be set by the facility administrator, or may be set based on the time it takes for hands to become dirty again after washing.

The facility may be any one of multiple facilities belonging to a series, and the discount right or valuable value granted to the user as a specific effect may be usable at multiple facilities in the series to which the facility belongs. For example, the facility may be one of the stores in the same chain. The granting unit 2034 grants a predetermined number of discount coupons to a user who washes their hands using the hand-washing device 1, and the discount coupons can be used not only at the store where the hand-washing device 1 is installed, but also at other stores in the same chain.

Furthermore, the specific effect may be the right to use a specified service. For example, the specified service is a service that can be used by entering a specified location within the facility in which the hand-washing device 1 is installed, or a transportation service provided by the facility. For example, the hand-washing device 1 is installed near the entrance of a restaurant, and a user who washes his/her hands using the hand-washing device 1 is granted the right to enter the restaurant and use food and drink services within the restaurant as a specified effect. Also, for example, the hand-washing device 1 is installed near the entrance of a train station, and a user who washes his/her hands using the hand-washing device 1 is granted the right to enter the station and use trains as a specified effect.

The right to use a specific service may have an expiration date. For example, as a specific effect, the user may be granted the right to use a transportation service provided by the facility in which the hand-washing device 1 is installed. The right to use the transportation service can only be used within a specific period from the date of grant. When granting the right to use a specific service to the user, the granting unit 2034 presents information regarding the expiration date to the user. The expiration date may be set by the facility administrator, or may be set based on the time it takes for washed hands to become dirty again.

The granting unit 2034 may grant the predetermined effect to the user in the form of electronic data. For example, the granting unit 2034 grants electronic data of a discount coupon to the user's terminal device 10A. The electronic data may be granted by short-range wireless communication, by reading a predetermined optical code, by email, or by accessing a predetermined address. The granting unit 2034 may communicate with the hand-washing device 1 and issue the predetermined effect in an analog form by the hand-washing device 1 to grant it to the user. For example, the granting unit 2034 prints a discount coupon on paper by the hand-washing device 1 and grants it to the user.

The presentation unit 2035 presents to visitors to the facility the situation in which visitors to the facility have used the hand-washing device 1. For example, the presentation unit 2035 presents information regarding the number of visitors who have used the hand-washing device 1 during a specified time period. The presentation unit 2035 may analyze and present the trend in the number of visitors who have used the hand-washing device 1 based on the information regarding the number of visitors who have used the hand-washing device 1. For example, the presentation unit 2035 presents the trend in the number of people using the hand-washing device 1 by time in a form that is easy for visitors to visually recognize, such as a graph, image, or video.

The presentation unit 2035 may also determine the percentage of visitors to the facility who have used the hand-washing device 1 based on the result of counting the number of visitors to the facility during a specified time period and the usage history of the hand-washing device 1. The presentation unit 2035 presents the determined percentage to visitors to the facility by displaying it on the terminal device 10B of the administrator who manages the hand-washing device 1. The presentation unit 2035 may also cause the terminal device 10B to display the number of visitors who have used the hand-washing device 1. The presentation unit 2035 may also cause the terminal device 10B to display the number of times the hand-washing device 1 has been used per specified time period, for example, the number of times the hand-washing device 1 has been used in the last minute.

The presentation unit 2035 may also present to visitors the status of handwashing using the handwashing device 1 and the status of sterilization using the UV sterilization device 80 separately. For example, the presentation unit 2035 causes the terminal device 10B to display the number of visitors who washed their hands using the handwashing device 1, the percentage of visitors who washed their hands, the number of times handwashing occurred per specified time, etc. For example, the presentation unit 2035 causes the terminal device 10B to display the number of visitors who sterilized their portable items using the UV sterilization device 80, the percentage of visitors who sterilized their portable items, the number of times sterilization occurred per specified time, etc. The presentation unit 2035 may also display the status of handwashing and the status of sterilization simultaneously on the terminal device 10B.

<3 Operation>
<3.1 Processing for imparting a specific effect to the user>
Hereinafter, with reference to FIG. 18, a process for imparting a specific effect to a user who uses the hand-washing device 1 will be described.

In step S181, the acquisition unit 2033 of the server 200 acquires information on the user's use of the hand-washing device installed in the facility. Specifically, the hand-washing device 1 stores a usage history of the hand-washing device 1. The acquisition unit 2033 acquires information on the usage history of the hand-washing device 1 from the hand-washing device 1. Note that the monitoring device 300 may store, for example, the usage history of the hand-washing device 1 as monitoring data, and the acquisition unit 2033 may acquire information on the usage history of the hand-washing device 1 from the monitoring device 300.

In step S182, the granting unit 2034 of the server 200 grants the user an advantageous effect when using a facility in which the hand-washing device 1 is installed, based on information about the user's use of the hand-washing device. For example, the granting unit 2034 grants the user an advantageous effect when using a facility in which the hand-washing device 1 is installed, at the time when the user finishes using the hand-washing device 1. Note that the granting unit 2034 may grant a specific effect at other times.

The specific effect may be, for example, a discount right available at the facility, or a valuable value. For example, the specific effect may be a percentage coupon, points, virtual currency, or the like available at the facility. Note that the specific effect is not limited to the above, and may be anything that is beneficial to the user.

This can provide incentives to users and encourage them to use the hand-washing devices. It can also encourage users to use the facilities by providing them with specific effects that can be used at the facilities where the hand-washing devices are installed.

In step S182, the granting unit 2034 may specify the content of the effect based on the use history of the hand-washing device 1 and a preset granting rule, and grant the effect to the user. The granting rule may be presented to visitors to the facility. For example, the granting unit 2034 specifies the type and quantity of the effect to be granted to the user based on the history of the user washing his/her hands using the hand-washing device 1, or the history of the user sterilizing his/her portable items using the UV sterilization device 80 of the hand-washing device 1. For example, the granting unit 2034 grants a predetermined number of discount coupons to a user who washed his/her hands using the hand-washing device 1. In addition, the granting unit 2034 grants a predetermined number of points to a user who sterilized his/her portable items using the UV sterilization device 80 of the hand-washing device 1. Then, the granting unit 2034 grants a predetermined number of discount coupons and a predetermined number of points to a user who both washed his/her hands and sterilized his/her portable items. Note that the granting unit 2034 may grant a predetermined effect only to a user who both washed his/her hands and sterilized his/her portable items.

This allows the content of the effect to be given to the user to be specified according to the preset rules. In addition, by presenting the rules to be given to visitors to the facility, the visitors can be encouraged to use the hand-washing device in accordance with the rules.

In addition, in step S182, the discount right or valuable value granted to the user as the specific effect may have an expiration date. For example, the specific effect may be a discount coupon that can be used at a facility, and the discount coupon can only be used within a specified period from the date of grant. When granting the discount right or valuable value to the user, the granting unit 2034 presents information regarding the expiration date to the user. In addition, the expiration date may be set by the facility administrator, or may be set based on the time it takes for washed hands to become dirty again. The time it takes for washed hands to become dirty again is set in advance based on, for example, the results of a specified experiment regarding the growth of bacteria on hands.

This will encourage users to use certain effects before their expiration date, encouraging them to use the facility early. It will also encourage users to use certain effects before their hands get dirty over time, improving the hygiene level of the facility.

In step S182, the facility may be one of multiple facilities belonging to a series, and the discount right or valuable value granted to the user as a specific effect may be usable at multiple facilities in the series to which the facility belongs. For example, the facility may be one of the stores in the same chain. The granting unit 2034 grants a predetermined number of discount coupons to a user who washes their hands using the hand-washing device 1, and the discount coupons can be used not only at the store where the hand-washing device 1 is installed, but also at other stores in the same chain.

This will broaden the scope of use of certain effects, improving the user experience and encouraging use of multiple facilities in the same chain.

In addition, in step S182, the specific effect may be the right to use a specified service. For example, the specified service is a service that can be used by entering a specified location within the facility in which the hand-washing device 1 is installed, or a transportation service provided by the facility. For example, the hand-washing device 1 is installed near the entrance of a restaurant, and a user who washes his/her hands using the hand-washing device 1 is granted the right to enter the restaurant and use food and beverage services within the restaurant as a specified effect. Also, for example, the hand-washing device 1 is installed near the entrance of a train station, and a user who washes his/her hands using the hand-washing device 1 is granted the right to enter the train station and use trains as a specified effect.

This provides an incentive to users and encourages them to use the hand-washing device. In addition, it is possible to restrict access to a particular service to only users who have used the hand-washing device, thereby improving the hygiene standards of facilities that provide the particular service.

In step S182, the right to use the specified service may be set with an expiration date. For example, as a specific effect, the user may be granted the right to use a transportation service provided by the facility in which the hand-washing device 1 is installed. The right to use the transportation service can only be used within a specified period from the date of grant. When granting the right to use the specified service to the user, the granting unit 2034 presents information regarding the expiration date to the user. In addition, the expiration date may be set by the facility administrator, or may be set based on the time it takes for washed hands to become dirty again.

This will encourage users to use the specified service within the expiration date, encouraging them to use the facility early. It will also encourage users to use the specified service before their hands get dirty over time, improving the hygiene level of the facility.

In addition, in step S182, the granting unit 2034 may grant the predetermined effect to the user in the form of electronic data. For example, the granting unit 2034 grants electronic data of a discount coupon to the user's terminal device 10A. The granting unit 2034 may communicate with the hand-washing device 1, issue the predetermined effect in an analog form by the hand-washing device 1, and grant it to the user. For example, the granting unit 2034 prints a discount coupon on paper by the hand-washing device 1 and grants it to the user.

This allows the desired effect to be bestowed on the user.

<3.2 Processing to display the hand-washing station usage rate>
Hereinafter, with reference to Figure 19, a process of presenting to visitors the percentage of visitors who have used the hand-washing device 1 among all visitors to the facility will be described.

In step S191, the transceiver 182B of terminal device 10B acquires from the server 20 the usage history of the hand-washing device 1 installed in the facility of the manager of terminal device 10B. For example, terminal device 10B acquires from the server 20 information contained in the hand-washing device usage history database 281, the hand-washing device usage status database 283, or both, and acquires information regarding the number of people using the hand-washing device 1, the number of people who washed their hands, the number of people who sterilized, and the trends in the number of people using the hand-washing device 1. Terminal device 10B may acquire information from the server 20 in real time, or at predetermined intervals.

In step S192, the display control unit 183B of the terminal device 10B determines the percentage of visitors to the facility who used the hand-washing device 1 based on the results of counting the number of visitors to the facility during a specified time period and the usage history of the hand-washing device 1.

In step S193, the display control unit 183B of the terminal device 10B displays the ratio on the display 132 of the terminal device 10B and presents it to visitors to the facility.

In addition, in step S193, the display control unit 183B of the terminal device 10B may display information on the number of people using the hand-washing device 1, the number of people who washed their hands, the number of people who sterilized, and the trend in the number of users, based on the information regarding the usage status of the hand-washing device acquired from the server, on the display 132 of the terminal device 10B, and present this information to visitors to the facility. For example, the presentation unit 2035 presents the trend in the number of people using the hand-washing device 1 by hour in a form that is easy for visitors to see, such as a graph, image, or video.

This allows visitors to be informed of the utilization rate and utilization status of the hand-washing devices installed in the facility, allowing them to understand the hygiene level of the facility and use the facility with peace of mind. Also, by letting visitors know that other visitors have used the hand-washing devices, it is possible to encourage more visitors to use the hand-washing devices.

<4 Screen example>
20 and 21 are diagrams showing example screens of a terminal device 10A of a user who uses the hand-washing device 1. Fig. 22 is a diagram showing an example screen of a terminal device 10B of an administrator who manages the hand-washing device 1.

Figure 20 shows a situation in which a user who has used the hand-washing device 1 is granted a special effect, such as a right to a discount that can be used in the facility in which the hand-washing device 1 is installed, or a valuable value. As shown in Figure 20, information indicating the content, quantity, and expiration date of the special effect granted by using the hand-washing device 1 is displayed on the display 132 of the user's terminal device 10A. Also displayed is an operation button 1321 for receiving the special effect.

This provides an incentive, increases user satisfaction, and encourages use of the hand-washing device. It is also possible to encourage use of the facility by providing specific effects that can be used at the facility where the hand-washing device is installed.

Figure 21 shows a situation in which a user who has used the hand-washing device 1 is granted the authority to enter the facility in which the hand-washing device 1 is installed as a specific effect. As shown in Figure 21, the display 132 of the user's terminal device 10A displays information indicating that an admission ticket to the facility has been granted as a result of using the hand-washing device 1. An operation button 1322 for receiving the admission ticket is also displayed.

This provides an incentive, increases user satisfaction, and encourages use of the hand-washing device. It also allows only users who have used the hand-washing device to enter the facility, improving the hygiene level of the facility.

Figure 22 is a diagram showing a situation in which the utilization rate of the hand-washing station 1 is displayed on the terminal device 10B of the manager who manages the hand-washing station 1 and presented to visitors. As shown in Figure 22, the display 132 of the terminal device 10B that presents information to visitors displays the percentage of visitors to the facility who have used the hand-washing station 1, as well as the content of the specific effects that can be obtained by using the hand-washing station 1. The installation location of the hand-washing station 1 is also displayed.

This allows visitors to know the hygiene level of the facility by showing them the usage rate of the hand-washing stations installed in the facility, allowing them to use the facility with peace of mind. Also, by letting visitors know that other visitors have used the hand-washing stations, it is possible to encourage more visitors to use the hand-washing stations.

In addition, by presenting the details of the specific benefits that can be obtained by using the hand-washing devices, it is possible to generate interest in the devices and encourage their use. And by displaying the locations where the hand-washing devices are installed, it is possible to guide visitors to the hand-washing devices.

The system 1000 may be provided with a function to notify the user's terminal device 10A of the presence of the hand-washing device 1 and encourage its use. This function is realized, for example, by using short-range wireless communication. Short-range wireless communication is realized, for example, by technologies such as Bluetooth (registered trademark) and BLE (Bluetooth Low Energy). Specifically, for example, the hand-washing device 1 is provided with a short-range communication unit that can reach a predetermined range and transmits a beacon signal including information for identifying the hand-washing device 1. The terminal device 10A has a function to receive the beacon signal transmitted by the short-range communication unit. Furthermore, the terminal device 10A stores an application for using the hand-washing device 1.

When the terminal device 10A enters within the range of the beacon signal, it receives the beacon signal. When the terminal device 10A receives the beacon signal, it launches an application corresponding to the beacon signal, that is, an application for using the hand-washing device 1. The terminal device 10A accesses the server 200, for example, by a function realized by the application, and requests the server 200 for information notifying the presence of the hand-washing device 1 corresponding to the beacon signal and information encouraging the use of the hand-washing device 1. The server 200 grasps the location of the user using the terminal device 10A by this request. When the server 200 is requested for information notifying the presence of the hand-washing device 1 and information encouraging the use of the hand-washing device 1, it transmits the requested information to the requesting terminal device 10A. The terminal device 10A receives the information notifying the presence of the hand-washing device 1 and information encouraging the use of the hand-washing device 1, and displays the received information on the display 132. Note that the short-range communication unit does not have to be installed in the hand-washing device 1 as long as it can communicate with a user approaching the hand-washing device 1. For example, the short-range communication unit may be installed in a location near the hand-washing device 1.

Figure 23 is a diagram showing an example of information about the hand-washing device 1 displayed on the user's terminal device 10A. As shown in Figure 23, on the display 132 of the terminal device 10A, content encouraging use of the hand-washing device 1 is displayed, along with the installation location of the hand-washing device 1. As shown in Figure 23, the content encouraging use of the hand-washing device 1 may include content about specific effects that can be obtained by using the hand-washing device 1. This makes it possible to encourage use of the hand-washing device 1 through push notifications using short-range wireless communication technology.

The terminal device 10A may automatically or with the consent of the user request the server 200 to send information informing the user of the presence of the hand-washing device 1 and information encouraging the user to use the hand-washing device 1. When the request for information to the server 200 is automatically sent, the server 200 may check the usage history of the terminal device 10A that requested the information. If the user of the terminal device 10A has used the hand-washing device 1 within a specified period of time, the server 200 will not transmit the requested signal. This prevents unnecessary promptings to use the hand-washing device 1.

Furthermore, the terminal device 10A may transmit a beacon signal that can be received by the hand-washing device 1 using the application. The hand-washing device 1 or the server 200 calculates the distance between the hand-washing device 1 and the terminal device 10A based on the signal strength of the beacon signal that the hand-washing device 1 receives from the terminal device 10A. As a result, the hand-washing device 1 or the server 200 may determine whether the user has approached the hand-washing device 1 or left the hand-washing device 1, and further calculate the time the user was near the hand-washing device 1. The hand-washing device 1 or the server 200 may also select the hand-washing device 1 that is closest to the terminal device 10A.

This allows the system to detect when a user is approaching the hand-washing device and prompt the approaching user to use the hand-washing device.

For example, the hand-washing device 1 may be configured to return a response signal when it receives a beacon signal transmitted from the terminal device 10A. The terminal device 10A transmits a beacon signal and, for example, requests information about the hand-washing device 1 having the strongest response signal to the transmitted beacon signal from the server 200. The server 200 transmits the requested information about the hand-washing device 1 to the terminal device 10A. The terminal device 10A receives the information about the hand-washing device 1 and displays the received information on the display 132. This allows the terminal device 10A to obtain the location of the nearest hand-washing device 1.

The server 200 may also present the installation locations of multiple hand-washing devices 1 to the user in a form that the user can recognize. For example, an application for using the hand-washing device 1 is installed on the user's terminal device 10A. The server 200 may display the installation locations of all hand-washing devices 1 on a map and present them in the application. The server 200 may also display the installation locations of hand-washing devices 1 near the user or hand-washing devices 1 installed in facilities visited by the user on a map based on the user's location information and present them in the application. The server 200 may also display a notification in the application that a specific effect has been given to the user who used the hand-washing device 1. The application for using the hand-washing device 1 may be equipped with a function for receiving a beacon signal transmitted by the hand-washing device 1.

This allows the location of the hand washing device to be displayed to the user in an easy-to-understand manner.

In the above, an example of determining the user's location using short-range wireless communication technology has been described, but the user's location may also be determined using technology other than short-range wireless communication technology. For example, the GPS function of the terminal device 10A may be used to determine the user's location. Specifically, for example, the server 200 receives location information of the terminal device 10A from the terminal device 10A at a predetermined cycle. When the server 200 determines that the terminal device 10A has entered within a predetermined range from the installation position of the hand-washing device 1, it transmits information to the terminal device 10A informing it of the presence of the hand-washing device 1 and information encouraging the use of the hand-washing device 1.

<Modification>
The system 1000 may determine whether a user is using the hand-washing device 1 fraudulently in order to obtain a specific effect. Specifically, the server 200 may determine whether the use is fraudulent based on the usage history of the hand-washing device 1. If the server 200 determines that the use is fraudulent, it does not grant a specific effect to the fraudulent use. For example, the server 200 determines that the use is fraudulent based on a usage history in which the same user has used the hand-washing device 1 multiple times in succession. The server 200 grants a specific effect to the user only for the first use of the hand-washing device. Also, for example, the server 200 determines that the use is fraudulent based on a usage history in which the user is located near the hand-washing device 1 but water is not running. The server 200 does not grant a specific effect to the user.

This prevents users from misusing the hand washing device to obtain a specific effect.

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.
