An embodiment of the present disclosure will be described.

<Configuration of hygiene management system>
First, the configuration of the sanitation management system will be described. Fig. 1 is a block diagram showing the schematic configuration of the sanitation management system.

The hygiene management system 10 shown in FIG. 1 manages the sterilization status in a restaurant. The targets for which the hygiene management system 10 manages the sterilization implementation status (sterilization status) may also be, for example, elderly housing, accommodation facilities, hospitals, or libraries. The hygiene management system 10 comprises a sanitized water generating device 1, a spray bottle 2, a server device 3, a user terminal device 4, an entrance terminal device 5, and a table terminal device 6. The number of sanitized water generating devices 1, spray bottles 2, server devices 3, user terminal devices 4, entrance terminal devices 5, and table terminal devices 6 that make up the hygiene management system 10 is not limited to the number shown in FIG. 1.

The sanitized water generating device 1 is an example of a disinfectant generating device and is installed, for example, in the kitchen of a restaurant. The sanitized water generating device 1 generates sanitized water to be used for disinfection. Sanitized water is an example of a disinfectant.

The spray bottle 2 is an example of a sterilization device that sterilizes an object by spraying sanitized water onto the object. Examples of objects to be sterilized include tables, chairs, cooking utensils, toilets, and hands. Examples of cooking utensils to be sterilized include cutting boards, knives, and pots. Note that, below, a spray bottle 2 used to sterilize items other than hands may be referred to as an "object spray bottle 2A." A spray bottle 2 used to sterilize hands in places other than restrooms (e.g., break rooms) may be referred to as a "hand spray bottle 2B." A spray bottle 2 used to sterilize hands in restrooms may be referred to as a "toilet hand spray bottle 2C." The object spray bottle 2A is carried, for example, by restaurant staff. The hand spray bottle 2B is placed in places other than restrooms, such as the kitchen or staff break room. The toilet hand spray bottle 2C is placed, for example, on a restroom sink.

The server device 3 is located, for example, outside the restaurant. However, the server device 3 may also be located inside the restaurant. The server device 3 is configured to be able to send and receive various information between the user terminal device 4, entrance terminal device 5, and table terminal device 6 via the communication network N. The server device 3 stores various information related to the sterilization status.

The user terminal device 4 is an example of a hygiene management device, and is carried by restaurant managers and staff who move around the dining area of the restaurant. The user terminal device 4 is used to register various information used to manage the sterilization status to the server device 3, and to check the sterilization status, etc.

The entrance terminal device 5 is installed at the entrance of the restaurant. The table terminal device 6 is placed at a table T in the eating and drinking space. The entrance terminal device 5 and the table terminal device 6 can notify the sterilization status of the restaurant using at least one of images and audio, for example, based on item sterilization history information (described below) stored in the server device 3 or the user terminal device 4.

In addition, items to be sterilized in restaurants are each attached with an item tag G1, which is composed of, for example, an NFC (Near Field Communication) tag (electronic tag). Items to which the item tag G1 is attached include, for example, a table T, cooking utensils, or a toilet. The item tag G1 records an item ID unique to each item. The item ID is an example of information that indicates the item to be sterilized. The item ID identifies the item and the store. The item ID is read by the user terminal device 4 when the item is sterilized. Note that if it is difficult to attach an item tag G1 to an item, the item tag G1 may be attached to a wall or another item located near the item. Furthermore, instead of attaching an item tag G1 to each of multiple items, the item tags G1 of multiple items may be attached together on a single piece of paper, wall, etc.

In addition, a user tag, such as an NFC tag (electronic tag), is attached to each manager and staff member's name tag. The user tag records the manager's or staff member's unique user ID. Note that when there is no need to specifically distinguish between the manager and staff member, at least one of the manager and staff member may be referred to as a user.

Next, we will explain the details of each component of the sanitation management system 10. Figure 2 is a schematic diagram showing the general configuration of the sanitary water generating device and spray bottle. Figure 3 is a block diagram showing the general configuration of the server device. Figure 4 is a block diagram showing the general configuration of the user terminal device.

As shown in FIG. 2, the sanitary water generating device 1 includes a generating unit 11, a supply unit 12, a writing unit 13, a display unit 14, and a generation control unit 15.

Based on the control of the generation control unit 15, the generation unit 11 generates carbonated electrolyzed hypochlorous acid water as sanitary water, for example, as follows. First, the generation unit 11 electrolyzes saturated brine in a brine tank in an electrolytic cell and then mixes it with water to generate electrolyzed hypochlorous acid water. The generation unit 11 generates carbonated electrolyzed hypochlorous acid water by mixing carbon dioxide gas with the electrolyzed hypochlorous acid water. The generation unit 11 may also be configured with an electrolysis line that electrolyzes saturated brine to generate an electrolyte, a dilution line that mixes carbon dioxide gas with water to generate carbonated water, and a mixing line that mixes the electrolyte and carbonated water to generate carbonated electrolyzed hypochlorous acid water. Alternatively, low-salinity brine other than saturated brine may be electrolyzed and then mixed with water to generate electrolyzed hypochlorous acid water, and the generated electrolyzed hypochlorous acid water may be mixed with carbon dioxide gas to generate carbonated electrolyzed hypochlorous acid water. In this case, the low-salinity brine may be provided in a tank or by in-line mixing of saturated brine and dilution water.

The carbonated electrolytic hypochlorous water produced in this manner has an effective chlorine concentration (concentration of active ingredients) of, for example, 25 ppm to 200 ppm, and a pH of 5 to 6.5. Hereinafter, the effective chlorine concentration may be referred to as "concentration." The concentration at the time of production by the generator 11 may be referred to as "initial concentration." Carbonated electrolytic hypochlorous water with these characteristics has a disinfecting power approximately 80 times that of sodium hypochlorite at the same concentration. Carbonated electrolytic hypochlorous water also has the characteristic of decreasing in concentration and disinfecting power over time. The generator 11 can also produce electrolytic hypochlorous water that does not contain carbon dioxide. Examples of electrolytic hypochlorous water include those with an active ingredient concentration of 40 ppm to 200 ppm and a pH of 7.5 or higher. Hereinafter, carbonated electrolytic hypochlorous water or electrolytic hypochlorous water may be referred to as "sanitary water."

The supply unit 12 supplies the sanitized water generated by the generation unit 11 to the spray bottle 2.

Based on the control of the production control unit 15, the writing unit 13 writes the initial concentration, expiration date, and production date and time of the sanitized water supplied to the spray bottle 2 to the bottle tag G2 (described below) of the spray bottle 2. The initial concentration and expiration date of the sanitized water written to the bottle tag G2 are examples of parameters that indicate the effectiveness of the sanitized water at the time of its production. The parameters that indicate the effectiveness are examples of the sterilization content. The writing unit 13 constitutes a parameter output unit that outputs parameters that indicate the effectiveness of the sanitized water.

The display unit 14 is an example of a notification unit, and displays various information based on the control of the generation control unit 15.

The production control unit 15 associates the initial concentration of the sanitized water, its expiration date, production date and time, and management number, and stores them in memory (not shown). The production control unit 15 causes the display unit 14 to display the expiration date of the sanitized water produced on a specified date and time based on operation of an operation unit (not shown). By displaying the expiration date of the sanitized water on the sanitized water generating device 1 in this way, staff, for example, can easily recognize how long the sanitized water can be used, allowing for appropriate hygiene management. The expiration date of the sanitized water may also be announced by sound from the sanitized water generating device 1.

The spray bottle 2 comprises a bottle section 21, a spray section 22, and a beacon signal transmission section 23.

The bottle unit 21 is an example of a container. Sanitized water is stored in the bottle unit 21. A bottle tag G2 is fixed to the bottle unit 21. The bottle tag G2 is configured, for example, as an NFC tag (electronic tag). A bottle ID unique to the spray bottle 2 is recorded on the bottle tag G2. The bottle ID is an example of information representing the sterilization device. The initial concentration, expiration date, and production date and time of the sanitized water in the bottle unit 21 are recorded on the bottle tag G2. The spray unit 22 is an example of a discharge unit. The spray unit 22 has a trigger 221, which is an example of an operation unit, and sprays an amount of sanitized water according to the number of times the trigger 221 is operated. The beacon signal transmitter 23 transmits the same number of beacon signals as the number of times the trigger 221 is operated. The beacon signal is an example of information representing the amount of sanitized water used during sterilization. The amount of sanitized water used during sterilization is an example of the content of sterilization. The beacon signal transmitter 23 is an example of a transmitter that outputs information representing the amount of sanitized water used. The beacon signal transmitted from the beacon signal transmitter 23 contains information representing the beacon ID, which is a unique identifier of the sterilization device and is unique to the sprayer 22.

Next, the server device 3 will be described. As shown in FIG. 3, the server device 3 includes a server DB (database) 31 and a server control unit 32.

Server DB31 stores user information corresponding to each user. The user information includes information representing the user's name and user ID.

Server DB31 stores item information corresponding to each item to be sterilized. The item information includes information indicating the item's name (and location), item ID, appropriate number of sprays, and appropriate concentration. The appropriate number of sprays is the number of sprays of sanitized water required to properly sterilize the item. The appropriate concentration is the concentration of sanitized water required to properly sterilize the item. Because viruses such as norovirus are more likely to be present in toilets than in items other than toilets, it is preferable that the appropriate concentration for toilets be higher than the appropriate concentration for items other than toilets.

Server DB31 stores appropriate concentration information for hands. The appropriate concentration information for hands includes information indicating the location where hands are sterilized (toilet or a location other than a toilet) and the appropriate concentration. The appropriate concentration is the concentration of sanitized water required to properly sterilize hands. Because viruses such as norovirus are more likely to be present in toilets than in other locations, it is preferable that the appropriate concentration when sterilizing hands in toilets be higher than the appropriate concentration when sterilizing hands in locations other than toilets.

Server DB31 stores basic bottle information corresponding to each spray bottle 2 (object spray bottle 2A, hand spray bottle 2B, toilet hand spray bottle 2C). The basic bottle information includes information common to each spray bottle 2. The basic bottle information includes information indicating the name (and location) of the spray bottle 2, the bottle ID, the amount of sanitized water sprayed when the trigger 221 is operated once, the capacity of the bottle portion 21, the remaining amount of sanitized water, the warning threshold, the expiration date and production date and time of the sanitized water, and the purpose. The remaining amount of sanitized water is updated according to the actual remaining amount. The warning threshold is the remaining amount that serves as the reference for issuing a warning that the remaining amount of sanitized water is low. The purpose indicates whether the spray bottle 2 is for sterilizing objects, sterilizing hands in places other than the toilet, or sterilizing hands in the toilet.

The server DB31 stores product bottle information related to the product spray bottle 2A. The product bottle information includes information representing the user ID of the user using the product spray bottle 2A, the bottle ID of the product spray bottle 2A, the expiration date, initial concentration, and production date and time of the sanitized water, and the beacon ID of the spray unit 22.

The server DB31 stores hand bottle information related to the hand spray bottle 2B. The hand bottle information includes information representing the bottle ID of the hand spray bottle 2B, the expiration date, initial concentration, and production date and time of the sanitized water, and the beacon ID of the spray unit 22.

Server DB31 stores toilet hand bottle information related to the toilet hand spray bottle 2C. The toilet hand bottle information includes information representing the bottle ID of the toilet hand spray bottle 2C, the expiration date, initial concentration and production date/time of the sanitized water, and the beacon ID of the spray unit 22.

The server DB31 stores sterilization plan information. The sterilization plan information includes information indicating the user ID of the staff member performing the sterilization, the item ID of the item to be sterilized, and the date and time of sterilization.

The server DB31 stores item sterilization history information that indicates the status of sterilization of items. The item sterilization history information includes information indicating the user ID of the staff member who sterilized the item, the bottle ID of the spray bottle 2 used for sterilization, the item ID of the sterilized item, the estimated concentration of the sanitized water at the time sterilization was performed, the expiration date and number of sprays, and the date and time of sterilization.

Server DB31 stores hand sanitization history information that indicates the implementation status of hand sanitization. The hand sanitization history information includes information indicating the user ID of the staff member who sanitized the hands, the bottle ID of the spray bottle 2 used for sanitization, the estimated concentration of the sanitized water at the time of sanitization, the expiration date and number of sprays, the date and time of sanitization, and the location where the hands were sanitized. The location where the hands were sanitized may be a toilet or a location other than a toilet.

User information, item bottle information, sterilization plan information, item sterilization history information, and hand sterilization history information are associated by a user ID. Bottle basic information, item bottle information, hand bottle information, or toilet hand bottle information, item sterilization history information, and hand sterilization history information are associated by a bottle ID. Note that the configuration of each piece of information stored in server DB31 is merely an example, and other configurations may also be applied.

When the server control unit 32 acquires user information, item information, appropriate concentration information for hands, basic bottle information, item bottle information, hand bottle information, toilet hand bottle information, sterilization plan information, item sterilization history information, or hand sterilization history information generated by the user terminal device 4, it stores the information in the server DB 31 and transmits the stored information to the user terminal device 4 that did not generate it. Through this processing by the server control unit 32, the same information is shared between the server device 3 and the user terminal device 4.

Next, we will explain the user terminal device 4.

The user terminal device 4 shown in FIG. 4 is configured as, for example, a mobile terminal device such as a tablet terminal or a smartphone. The user terminal device 4 includes a communication unit 41, a reading unit 42, a beacon signal receiving unit 43, an imaging unit 44, a touch panel 45, a terminal DB (database) 46, a terminal storage unit 47, and a terminal control unit 48.

The communication unit 41 communicates with the server device 3. The reading unit 42 reads information recorded on the user tag, item tag G1, or bottle tag G2. The beacon signal receiving unit 43 receives a beacon signal from the beacon signal transmitting unit 23 of the spray bottle 2. The imaging unit 44 captures an image of the imaging target and generates a captured image. The touch panel 45 functions as a display unit that displays images based on the control of the terminal control unit 48, and as an operation unit that outputs an operation signal to the terminal control unit 48 in accordance with the contact state of a finger or the like on the touch panel 45.

The terminal DB 46 stores user information, item information, appropriate concentration information for hands, basic bottle information, item bottle information, hand bottle information, toilet hand bottle information, sterilization plan information, item sterilization history information, and hand sterilization history information. The terminal memory unit 47 stores various information necessary for the operation of the user terminal device 4.

The terminal control unit 48 has a CPU (Central Processing Unit), and the functions of the terminal control unit 48 are realized by the CPU executing a hygiene management program stored in the terminal memory unit 47. The terminal control unit 48 includes an authentication unit 481, an information reception unit 482, an appropriate number of sprays setting unit 483, an appropriate concentration setting unit 484, a remaining amount estimation unit 485, a concentration estimation unit 486, a warning unit 487, and a sterilization management unit 488.

The authentication unit 481 performs authentication processing for the user of the user terminal device 4, and places the user terminal device 4 having the authentication unit 481 in a state (logged-in state) in which various information can be sent and received between the user terminal device 4 having the authentication unit 481 and the server device 3 or other user terminal devices 4.

The information receiving unit 482 acquires information read from each tag by the reading unit 42. The information receiving unit 482 receives the user ID recorded in the user tag. The information receiving unit 482 is an example of a target information receiving unit that receives an item ID recorded in the item tag G1. The information receiving unit 482 is an example of a device information receiving unit that receives a bottle ID recorded in the bottle tag G2. The information receiving unit 482 is an example of a sterilization information receiving unit that receives the initial concentration and expiration date of the sanitized water recorded in the bottle tag G2. The information receiving unit 482 is also an example of a sterilization information receiving unit that receives the number of times the beacon signal is received by the beacon signal receiving unit 43 as the amount of sanitized water used during sterilization.

The appropriate number of sprays setting unit 483 sets the appropriate number of sprays of sanitized water for each sterilization target.

The appropriate concentration setting unit 484 sets the appropriate concentration of sanitized water for each sterilization target.

The remaining amount estimation unit 485 estimates the remaining amount of sanitized water in the spray bottle 2 when sterilization using sanitized water is performed.

The concentration estimation unit 486 estimates the concentration of sanitized water when sterilization using sanitized water is performed.

The warning unit 487 issues various warnings during sterilization.

The sterilization management unit 488 generates item sterilization history information and hand sterilization history information and stores them in the server DB 31 of the server device 3 and the terminal DB 46 of a user terminal device 4 that does not have the sterilization management unit 488.

Detailed processing performed by the appropriate injection count setting unit 483, appropriate concentration setting unit 484, remaining amount estimation unit 485, concentration estimation unit 486, warning unit 487, and sterilization management unit 488 will be described later. In the following, the user terminal device 4 held by the administrator may be referred to as the administrator terminal device 4A. The user terminal device 4 held by the staff may be referred to as the staff terminal device 4B.

<Operation of the hygiene control system>
Next, the operation of the hygiene management system will be described. Note that the various processing procedures shown below are merely examples, and other procedures may also be applied. Also, the following describes a case where the administrator terminal device 4A is used to register user information, product information, appropriate hand concentration information, basic bottle information, and sterilization plan information, but the staff terminal device 4B may also be used to register the above information.

<User Information Registration Process>
First, the user information registration process will be described.

When an administrator begins using the hygiene management system 10, he or she registers his or her own user information. The sterilization management unit 488 (hereinafter, sometimes referred to as the "sterilization management unit 488A") of the terminal control unit 48 (hereinafter, sometimes referred to as the "terminal control unit 48A") constituting the administrator terminal device 4A displays a user registration screen based on the administrator's operation of the touch panel 45 (hereinafter, sometimes referred to as the "touch panel 45A") of the administrator terminal device 4A. The administrator inputs the administrator's name and user ID based on the contents of the user registration screen. The sterilization management unit 488A generates user information including information based on the input operation and stores it in the terminal DB 46 (hereinafter, sometimes referred to as the "terminal DB 46A") of the administrator terminal device 4A. The generated user information is then transmitted to the server device 3 via the communication unit 41 (hereinafter, sometimes referred to as the "communication unit 41A") of the administrator terminal device 4A. The server control unit 32 of the server device 3 stores the user information in the server DB 31. The administrator also stores each staff member's user information in the server DB 31 by performing the same operations as the registration process for their own user information. The administrator also uses a writing device (not shown) to record the user ID on the user tag on the user's name tag.

After the above user information registration process is complete, when the user holds their name tag over the reading unit 42 of the manager terminal device 4A (hereinafter sometimes referred to as "reading unit 42A") or the reading unit 42 of the staff terminal device 4B (hereinafter sometimes referred to as "reading unit 42B"), authentication processing is performed based on the user ID read by the reading units 42A, 42B, and the server device 3 enters a state (login state) in which various information can be sent and received between the manager terminal device 4A or staff terminal device 4B. When the staff terminal device 4B enters the login state, the server control unit 32 sends the user information to the staff terminal device 4B and stores it in the terminal DB 46 (hereinafter sometimes referred to as "terminal DB 46B").

<Product Information Registration Process>
Next, the item information registration process will be described. The item information registration process is performed, for example, when starting to use a new item to be sterilized. For example, in a logged-in state, the sterilization management unit 488A of the administrator terminal device 4A displays an item information registration screen based on the administrator's operation of the touch panel 45A. Based on the contents of the registration screen, the administrator inputs the name and item ID of the item and captures an image of the item using the imaging unit 44 (hereinafter sometimes referred to as the "imaging unit 44A") of the administrator terminal device 4A. The administrator also records the item ID on the item tag G1 using a writing device (not shown), and then attaches the item tag G1 to the item.

The appropriate spray count setting unit 483 of the administrator terminal device 4A (hereinafter sometimes referred to as the "appropriate spray count setting unit 483A") calculates the area of the sterilization site on the item based on the captured image generated by the imaging unit 44A. The appropriate spray count setting unit 483A determines the appropriate number of sprays of sanitary water based on, for example, information representing the relationship between the area of the sterilization site and the appropriate number of sprays of sanitary water. The appropriate number of sprays is set to a higher number the larger the area of the sterilization site. The appropriate spray count setting unit 483A may also determine the appropriate number of sprays based on information representing the relationship between the sterilization site and the appropriate number of sprays. The appropriate spray count setting unit 483A may also determine the appropriate number of sprays based on information representing the relationship between the name of the item and the appropriate number of sprays, for example, input by operating the touch panel 45A.

The appropriate concentration setting unit 484 of the administrator terminal device 4A determines the appropriate concentration of sanitized water for an item identified based on the captured image or the input name, based on information indicating the relationship between the type of item and the appropriate concentration of sanitized water. The appropriate concentration is set higher for items that require stronger sterilization. For example, the appropriate concentration for table T is set to 100 ppm, and the appropriate concentration for toilets is set to 200 ppm. The administrator may also be able to set the appropriate concentration at any concentration. With this configuration, if the rate of decrease in the concentration of sanitized water per unit time varies depending on the storage or use environment of the spray bottle 2, the administrator can set an appropriate appropriate concentration depending on the storage or use environment of the spray bottle 2. The appropriate concentration setting unit 484 may also set the appropriate concentration based on factors that affect the rate of decrease in the concentration of sanitized water per unit time, such as the temperature during storage or use of the spray bottle 2, whether the spray bottle 2 is stored or used indoors, and the material of the bottle portion 21, which are set by the administrator.

The sterilization management unit 488A generates item information indicating the item name, item ID, appropriate number of sprays, and appropriate concentration. The sterilization management unit 488A stores the generated item information in the terminal DB 46A, and also transmits it to the server device 3 via the communication unit 41A. Note that at least one of the appropriate number of sprays and appropriate concentration may be set to a value based on the administrator's operation of the touch panel 45A.

When the server control unit 32 of the server device 3 acquires item information, it stores the information in the server DB 31 and transmits it to any staff terminal devices 4B that do not store the item information. The sterilization management unit 488 (hereinafter sometimes referred to as the "sterilization management unit 488B") of the terminal control unit 48 (hereinafter sometimes referred to as the "terminal control unit 48B") acquires the item information via the communication unit 41 (hereinafter sometimes referred to as the "communication unit 41B") of the staff terminal device 4B, and stores the item information in the terminal DB 46B. Through the above process, the item information generated by the manager terminal device 4A is shared among the server device 3, the manager terminal device 4A, and the staff terminal device 4B. Hereinafter, the process of sharing information generated by the manager terminal device 4A or the staff terminal device 4B among the server device 3, the manager terminal device 4A, and the staff terminal device 4B will be referred to as the "sharing process." A detailed description of the sharing process will be omitted below.

<Registration process of appropriate concentration information for hands>
Next, the registration process of appropriate hand concentration information will be described. For example, in a logged-in state, the sterilization management unit 488A of the administrator terminal device 4A displays a registration screen for appropriate hand concentration information based on the administrator's operation of the touch panel 45A. The administrator inputs the location for sterilizing hands (toilet or a location other than the toilet) and the appropriate concentration based on the contents of the registration screen. The sterilization management unit 488A generates appropriate hand concentration information based on the input operation and stores it in the terminal DB 46A, while also transmitting it to the server device 3 via the communication unit 41A. The server control unit 32 of the server device 3, which has acquired the appropriate hand concentration information, performs a sharing process for the appropriate hand concentration information.

<Registration process for basic bottle information>
Next, the bottle basic information registration process will be described. The bottle basic information registration process is performed, for example, when starting to use a new spray bottle 2. For example, while logged in, the sterilization management unit 488A of the administrator terminal device 4A displays a bottle basic information registration screen based on the administrator's operation of the touch panel 45A. Based on the contents of the registration screen, the administrator inputs the name of the spray bottle 2, the bottle ID, the amount of sanitized water sprayed when the trigger 221 is operated once, the capacity of the bottle portion 21, the remaining amount of sanitized water (no remaining amount), the warning threshold, and the purpose. The administrator also holds the bottle tag G2 of the spray bottle 2A to be registered over the reading unit 42A. When the reading unit 42A reads the bottle tag G2, the information receiving unit 482 (hereinafter sometimes referred to as the "information receiving unit 482A") receives the expiration date and creation date and time recorded on the bottle tag G2. The administrator also records the bottle ID on the bottle tag G2 using a writing device (not shown) and then attaches the bottle tag G2 to the spray bottle 2.

The sterilization management unit 488A generates bottle basic information based on information based on input operations and the expiration date and time of production of the sanitized water received from the bottle tag G2. Alternatively, the spray bottle 2 may be provided with a communication function, and the sterilization management unit 488A may acquire the expiration date and time of production of the sanitized water from the spray bottle 2 via the communication unit 41A to generate the bottle basic information. The bottle basic information generated at this stage may not include the expiration date and time of production of the sanitized water. In this case, when the spray bottle 2 corresponding to the bottle ID included in the bottle basic information is used for the first time, the expiration date and time of production of the sanitized water may be added to the bottle basic information during the registration process of the item bottle information, hand bottle information, or toilet hand bottle information described below. The sterilization management unit 488A stores the generated bottle basic information in the terminal DB 46A and transmits it to the server device 3 via the communication unit 41A. The server control unit 32 of the server device 3, which has acquired the bottle basic information, performs a sharing process for the bottle basic information. If the basic bottle information shared at this stage does not include the expiration date and production date/time of the sanitized water, the server control unit 32 may obtain the expiration date and production date/time of the sanitized water from the production control unit 15 of the spray bottle 2 and register them in the basic bottle information.

<Registration process of sterilization plan information>
Next, the registration process of sterilization plan information will be described with reference to the drawings. Fig. 5A is a schematic diagram showing the general configuration of the sterilization plan registration screen. Fig. 5B is a schematic diagram showing the general configuration of the sterilization plan screen. Fig. 5C is a schematic diagram showing the general configuration of the sterilization check plan screen.

For example, in a logged-in state, the sterilization management unit 488 of the administrator terminal device 4A displays the sterilization plan registration screen 500 shown in FIG. 5A based on the administrator's operation of the touch panel 45A. The administrator operates the pull-down buttons 501 on the sterilization plan registration screen 500 to select the store, cleaning location (item ID of the item to be sterilized), time (sterilization date and time), and person in charge (user ID of the staff member performing the sterilization), and then operates the register button 502.

The sterilization management unit 488A acquires information based on the input operations and generates a sterilization plan. Then, the sterilization management unit 288A displays the sterilization plan screen 510 shown in FIG. 5B on the touch panel 45A based on the generated sterilization plan. The sterilization plan screen 510 displays, in list form, the cleaning location based on the item ID, the sterilization date and time, and the person in charge based on the user ID. The sterilization management unit 488 can also include a sterilization check plan in the sterilization plan. The sterilization management unit 488 generates a sterilization check plan based on the administrator's operation of the touch panel 45A and displays the sterilization check plan screen 520 shown in FIG. 5C. The sterilization check plan screen 520 displays, in list form, the cleaning location based on the item ID, the scheduled time period (the time period to be checked), and notes. For example, a comment such as "There is dirt on the table that cannot be removed" can be registered as a note. The sterilization management unit 488A stores the generated sterilization plan as sterilization plan information in the terminal DB 46A, and also transmits it to the server device 3 via the communication unit 41. The server control unit 32 of the server device 3 that has acquired the sterilization plan information performs a sharing process for the sterilization plan information. Note that the configurations of the sterilization plan registration screen 500, sterilization plan screen 510, and sterilization check plan screen 520 described above are merely examples, and other configurations may be used as appropriate.

<Registration process of product bottle information>
Next, the registration process of product bottle information will be described with reference to the drawings. The registration process of product bottle information is performed, for example, before sterilizing products using the product spray bottle 2A. If one staff member uses the same product spray bottle 2A all day, the registration process of product bottle information related to that product spray bottle 2A only needs to be performed once a day. On the other hand, if one staff member uses different product spray bottles 2A as needed, the registration process of product bottle information related to each product spray bottle 2A only needs to be performed. Figure 6 is a flowchart of the product bottle information registration process.

For example, in a logged-in state, the sterilization management unit 488B of the staff terminal device 4B displays a registration screen for product bottle information based on the staff member's operation of the touch panel 45 (hereinafter sometimes referred to as "touch panel 45B") of the staff terminal device 4B. Based on the contents of the registration screen, the staff member holds their name tag over the reading unit 42B of the staff terminal device 4B, and then holds the bottle tag G2 of the product spray bottle 2A to be registered over the reading unit 42B.

As shown in FIG. 6, the reading unit 42B of the staff terminal device 4B reads the user tag (step S1). Furthermore, the reading unit 42B reads the bottle tag G2 (step S2). Next, the information receiving unit 482 (hereinafter sometimes referred to as the "information receiving unit 482B") of the staff terminal device 4B receives the bottle ID, expiration date, and production date and time recorded on the bottle tag G2. The sterilization management unit 488B may also display the expiration date of the sanitized water in the product spray bottle 2A on the touch panel 45B. By displaying the expiration date of the sanitized water on the touch panel 45B, staff can easily know until when the sanitized water can be used, allowing for appropriate hygiene management.

The sterilization management unit 488B then identifies the bottle basic information corresponding to the product spray bottle 2A to be registered from the bottle basic information stored in the terminal DB 46B based on the bottle ID acquired by the information receiving unit 482B. The sterilization management unit 488B determines whether the date and time of production of the sanitized water acquired by the information receiving unit 482B is the same as the date and time of production of the sanitized water included in the bottle basic information corresponding to the product spray bottle 2A to be registered (step S3). In step S3, the date and time of production of the sanitized water acquired by the information receiving unit 482B is determined to be the same as the date and time of production of the sanitized water included in the bottle basic information if the sanitized water in the product spray bottle 2A has not been replaced, and the remaining amount of sanitized water is the same as the amount after the previous sterilization. On the other hand, the date and time of production of the sanitized water acquired by the information receiving unit 482B is determined to be different from the date and time of production of the sanitized water included in the bottle basic information if the sanitized water in the product spray bottle 2A has not been replaced.

If the sterilization management unit 488B determines that the creation date and time acquired by the information receiving unit 482 differs from the creation date and time included in the bottle basic information (step S3: NO), it updates the expiration date and creation date and time of the sanitized water included in the bottle basic information (step S4). Specifically, the sterilization management unit 488B updates the expiration date and creation date and time of the sanitized water included in the bottle basic information in the terminal DB 46B to the expiration date and creation date and time of the sanitized water acquired by the information receiving unit 482, and updates the remaining amount of sanitized water included in the bottle basic information to the capacity value of the bottle unit 21 included in the bottle basic information. The sterilization management unit 488B then transmits the updated bottle basic information to the server device 3 via the communication unit 41B. The server control unit 32 of the server device 3 that acquired the bottle basic information performs a sharing process for the bottle basic information.

If it is determined that the sanitized water generation date and time acquired by the information receiving unit 482B is the same as the sanitized water generation date and time in the bottle basic information (step S3: YES), or after the bottle basic information update process (step S4) has been performed, the warning unit 487 of the staff terminal device 4B (hereinafter sometimes referred to as the "warning unit 487B") determines whether the expiration date of the sanitized water has expired based on the expiration date acquired from the bottle tag G2 and the date and time the bottle tag G2 was read (step S5). If the warning unit 487B determines that the expiration date of the sanitized water has expired (step S5: YES), it issues a warning that the expiration date has expired (step S6). The warning unit 487B may display a warning on the touch panel 45B or may emit a warning sound from an audio output unit (not shown). Note that the warning in the process described below may be a visual or audible warning.

In this way, the validity of the sanitized water is managed based on the expiration date of the sanitized water obtained from the bottle tag G2, i.e., the expiration date output from the sanitized water generating device 1, so staff do not need to set the expiration date. Furthermore, when staff enter an expiration date, there is a risk of incorrect input, but because the validity of the sanitized water is managed based on the expiration date obtained from the bottle tag G2, staff can properly manage hygiene. In particular, if the validity of the sanitized water has expired, a warning is issued by the staff terminal device 4B, allowing staff to stop using the sanitized water and more properly manage hygiene.

When the warning process of step S6 is performed, the sterilization management unit 488B ends the registration process without generating product bottle information. Information indicating that the expiration date has passed may be recorded on the bottle tag G2 of the product spray bottle 2A for which the warning was issued. For example, a staff member or manager may use a writing device (not shown) to record information indicating that the expiration date has passed on the bottle tag G2. Alternatively, the user terminal device 4 may be provided with a function for recording information on the bottle tag G2, and a staff member or manager may use the user terminal device 4 to record information indicating that the expiration date has passed on the bottle tag G2.

On the other hand, if the sterilization management unit 488B determines that the expiration date of the sanitized water has not passed (step S5: NO), it displays a screen on the touch panel 45B prompting the staff member to operate the trigger 221 of the product spray bottle 2A. When the staff member operates the trigger 221, the beacon signal receiving unit 43B (hereinafter sometimes referred to as the "beacon signal receiving unit 43B") of the staff terminal device 4B receives a beacon signal from the product spray bottle 2A (step S7). The sterilization management unit 488B generates product bottle information including information representing the user ID, the bottle ID of the product spray bottle 2A, the expiration date, initial concentration, and generation date and time of the sanitized water, and the beacon ID based on the beacon signal, and stores (registers) this information in the terminal DB 46B (step S8). The sterilization management unit 488B also transmits the product bottle information to the server device 3 via the communication unit 41B. The server control unit 32 of the server device 3, which has acquired the product bottle information, performs a process for sharing the product bottle information. In addition, during the registration process of the item bottle information, the sterilization management unit 488B may estimate the concentration of the sanitized water at the date and time when the registration process was performed based on the initial concentration of the sanitized water recorded in the bottle tag G2 and the date and time when the registration process of the item bottle information was performed.

<Registration process of hand bottle information and toilet hand bottle information>
Next, the registration process for the hand bottle information and the toilet hand bottle information will be described with reference to the drawings. The registration process for the hand bottle information is performed after the hand spray bottle 2B is initially refilled with sanitary water or after the sanitary water in the hand spray bottle 2B is replaced. The registration process for the toilet hand bottle information is also performed at the same timing as the registration process for the hand bottle information. Note that the registration processes for the hand bottle information and the toilet hand bottle information are the same, so the registration process for the hand bottle information will be described below. Furthermore, processes similar to the registration process for the item bottle information will be assigned the same step numbers, and explanations will be omitted or simplified. Figure 7 is a flowchart of the registration process for the hand bottle information.

For example, when logged in, the sterilization management unit 488A of the administrator terminal device 4A displays a registration screen for hand bottle information based on the administrator's operation of the touch panel 45A. Based on the contents of the registration screen, the administrator holds the bottle tag G2 of the hand spray bottle 2B to be registered over the reading unit 42A of the administrator terminal device 4A.

As shown in FIG. 7, the reading unit 42A of the administrator terminal device 4A reads the bottle tag G2 of the hand spray bottle 2B (step S21). Next, the information receiving unit 482A of the administrator terminal device 4A receives the bottle ID, expiration date, and creation date and time recorded on the bottle tag G2. The sterilization management unit 488A then identifies the bottle basic information corresponding to the hand spray bottle 2B to be registered from the bottle basic information in the terminal DB 46A based on the bottle ID received by the information receiving unit 482A. The sterilization management unit 488A updates the expiration date and creation date and time of the sanitized water in the identified bottle basic information (step S4). The sterilization management unit 488A then transmits the updated bottle basic information to the server device 3 via the communication unit 41A. The server control unit 32 of the server device 3, which has acquired the bottle basic information, performs a sharing process for the bottle basic information.

After updating the bottle basic information (step S4), the sterilization management unit 488A displays a screen on the touch panel 45A prompting the administrator to operate the trigger 221 of the hand spray bottle 2B. When the administrator operates the trigger 221, the beacon signal receiving unit 43 (hereinafter sometimes referred to as the "beacon signal receiving unit 43A") of the administrator terminal device 4A receives a beacon signal from the hand spray bottle 2B (step S22). The sterilization management unit 488A generates hand bottle information including information representing the bottle ID of the hand spray bottle 2B, the expiration date, initial concentration, and generation date/time of the sanitized water, and the beacon ID based on the beacon signal, and stores (registers) this information in the terminal DB 46A (step S23). The sterilization management unit 488A also transmits the hand bottle information to the server device 3 via the communication unit 41A. The server control unit 32 of the server device 3, which has acquired the hand bottle information, performs a sharing process for the hand bottle information.

<Registration process of item sterilization history information>
Next, the registration process of item sterilization history information will be described with reference to the drawings. The registration process of item sterilization history information is performed each time an item is sterilized. The item is sterilized at a timing based on sterilization plan information or at a timing unrelated to the sterilization plan. Fig. 8 is a flowchart of the registration process of item sterilization history information. Fig. 9 is a schematic diagram showing the relationship between the concentration and the period elapsed since the date and time of sanitized water production.

For example, in a logged-in state, the sterilization management unit 488B of the staff terminal device 4B displays a registration screen for item sterilization history information based on the staff member's operation of the touch panel 45B. Based on the contents of the registration screen, the staff member holds the reading unit 42B over the item tag G1 of the item to be sterilized. As shown in FIG. 8, the reading unit 42B reads the item tag G1 (step S31). The information receiving unit 482B then receives the item ID recorded on the item tag G1. The sterilization management unit 488B also displays the appropriate number of sprays for the item to be sterilized on the touch panel 45B (step S32). In the processing of step S32, the sterilization management unit 488B identifies item information corresponding to the item to be sterilized from the item information in the terminal DB 46B based on the item ID received by the information receiving unit 482B. The sterilization management unit 488B displays the appropriate number of sprays included in the identified item information on the touch panel 45B. In this way, by notifying the staff of the appropriate number of sprays of sanitized water required to sterilize the item, the staff can easily recognize the appropriate number of sprays of sanitized water required to sterilize the item. Note that the sterilization management unit 488B does not need to perform the process of displaying the appropriate number of sprays on the touch panel 45B in step S32.

Next, the staff member operates the trigger 221 of the item spray bottle 2A to spray sanitized water onto the items to be sterilized. At this time, it is preferable that the staff member operates the trigger 221 the appropriate number of sprays or more. When the trigger 221 is operated, a number of beacon signals corresponding to the number of operations (number of sprays) is transmitted from the beacon signal transmitter 23 of the item spray bottle 2A. The beacon signal receiver 43B of the staff terminal device 4B receives the beacon signal corresponding to the number of operations of the trigger 221 (step S33). The information receiver 482B accepts the number of beacon signals received by the beacon signal receiver 43B as the number of sprays of sanitized water.

The sterilization management unit 488B identifies the item bottle information corresponding to the item spray bottle 2A used by the staff member from the item bottle information in the terminal DB 46B based on the user ID entered at the time of login. The sterilization management unit 488B may also identify the item bottle information corresponding to the item spray bottle 2A used by the staff member based on the beacon ID included in the beacon signal. Furthermore, the sterilization management unit 488B identifies the bottle basic information corresponding to the item spray bottle 2A from the bottle basic information in the terminal DB 46B based on the item ID included in the identified item bottle information. The remaining amount estimation unit 485 (hereinafter sometimes referred to as the "remaining amount estimation unit 485B") of the staff terminal device 4B then estimates the remaining amount of sanitized water in the item spray bottle 2A based on the identified bottle basic information (step S34). In the processing of step S34, the remaining amount estimation unit 485B calculates the amount of sanitized water sprayed during sterilization based on the amount of sanitized water sprayed when the trigger 221 included in the bottle basic information is operated once and the number of sprays based on the beacon signal. Next, the remaining amount estimation unit 485B subtracts the calculated spray amount from the remaining amount of sanitized water included in the bottle basic information to estimate the remaining amount of sanitized water after spraying.

The warning unit 487B determines whether the estimated remaining amount of sanitized water (estimated remaining amount) is less than the warning threshold included in the bottle basic information (step S35). If the warning unit 487B determines that the estimated remaining amount is less than the warning threshold (step S35: YES), it issues a warning that the remaining amount of sanitized water is low (step S36). When the staff member confirms the warning in step S35, it is preferable that after sterilization of the items is completed, the staff member replaces the sanitized water in the item spray bottle 2A and performs the item bottle information registration process. In this way, by issuing a warning that the remaining amount of sanitized water in the item spray bottle 2A is low, the staff member can easily recognize when it is time to replace the sanitized water. This type of warning is particularly effective when the inside of the bottle portion 21 is not visible.

On the other hand, if it is determined that the estimated remaining amount is not less than the warning threshold (step S35: NO), or after issuing a warning indicating that the remaining amount of sanitized water is low (step S36), the sterilization management unit 488B updates the remaining amount of sanitized water contained in the bottle basic information of the terminal DB 46B to the remaining amount estimated in step S34 (step S37). Thereafter, the concentration estimation unit 486 of the staff terminal device 4B (hereinafter sometimes referred to as the "concentration estimation unit 486B") estimates the concentration of the sanitized water based on the initial concentration and production date and time contained in the item bottle information and the sterilization date and time (date and time of reception of the beacon signal) (step S38). The concentration estimation unit 486 estimates the concentration of the sanitized water based on, for example, a relationship in which the longer the period since the production date and time, the greater the rate of decrease in concentration from the initial concentration. The concentration of sanitized water decreases approximately linearly over time, as shown in FIG. 9, for example. Figure 9 shows that the concentration of sanitized water for which the period elapsed from the date and time of generation is less than period A is above the appropriate concentration for toilets, and therefore the sanitized water can be used to disinfect toilets and tables. Figure 9 also shows that the concentration of sanitized water for which the period elapsed from the date and time of generation is more than period A but less than period B is below the appropriate concentration for toilets and above the appropriate concentration for tables, and therefore the sanitized water cannot be used to disinfect toilets but can be used to disinfect tables. Figure 9 also shows that the concentration of sanitized water for which the period elapsed from the date and time of generation is more than period B is below the appropriate concentration for toilets and tables, and therefore the sanitized water cannot be used to disinfect toilets and tables. A screen like the one shown in Figure 9 may be displayed on touch panel 45B as a screen showing the state (concentration) of the disinfectant liquid in spray bottle 2.

The warning unit 487B determines whether the estimated concentration of the sanitized water (estimated concentration) is less than the appropriate concentration included in the item information (step S39). If the warning unit 487B determines that the estimated concentration is less than the appropriate concentration (step S39: YES), it issues a warning that the concentration of the sanitized water is too low to be suitable for sterilizing items (step S40). Upon confirming the warning in step S40, it is preferable that, after sterilization of the items is completed, the staff member replaces the sanitized water in the item spray bottle 2A, performs the item bottle information registration process, and sterilizes the items again using the replaced sanitized water. In this way, a warning that the estimated concentration of the sanitized water is low is issued based on the initial concentration of the sanitized water included in the item bottle information, i.e., based on the initial concentration output from the sanitized water generating device 1. This allows the staff member to easily recognize that sterilization is not being performed using sanitized water of an appropriate concentration, allowing for appropriate hygiene management. In particular, because the appropriate concentration varies for each type of item, the staff member can easily recognize that sterilization is not being performed using sanitized water of an appropriate concentration for each type of item.

After the staff member sterilizes the item by wiping off the sanitized water sprayed on it with a cloth or the like, they again hold the reading unit 42B over the item tag G1 of the item to be sterilized. The reading unit 42B reads the item tag G1 (step S41). The processing of step S41 is performed when it is determined that the estimated concentration of the sanitized water is not below the appropriate concentration (step S39: NO) or after a warning processing indicating that the concentration of the sanitized water is low (step S40) is performed. The information receiving unit 482B then receives the item ID recorded on the item tag G1. The sterilization management unit 488B then generates item sterilization history information including information representing the user ID of the staff member who performed the sterilization, the bottle ID of the item spray bottle 2A used for sterilization, the item ID, the estimated concentration, expiration date and number of sprays of the sanitized water at the time of sterilization, and the sterilization date and time, and stores (registers) this information in the terminal DB 46B (step S42). In addition, the sterilization management unit 488B transmits the item sterilization history information to the server device 3 via the communication unit 41B. The server control unit 32 of the server device 3 that has acquired the item sterilization history information performs a sharing process for the item sterilization history information.

The sterilization management unit 488B may generate item sterilization history information if it is determined that the estimated concentration of sanitized water is not less than the appropriate concentration (step S39: NO) without reading the item tag G1 in step S41, or after the processing of step S40 has been performed. Furthermore, although the processing based on the remaining amount of sanitized water estimation result (steps S35-S37) is performed before the processing based on the concentration estimation result of sanitized water (steps S39-S40) is performed, these processes may be performed in the reverse order, or one of these processes may be performed in a different processing flow rather than in the registration process of item sterilization history information.

<Hand sanitization history information registration process>
Next, the process for registering hand sanitization history information will be described with reference to the drawings. The process for registering hand sanitization history information is performed each time a user's hands are sanitized. Note that the process for registering hand sanitization history information when sanitizing hands in a toilet and when sanitizing hands in a place other than a toilet is the same, so the process for registering hand sanitization history information when sanitizing hands in a place other than a toilet will be described. Furthermore, processes similar to the process for registering item sanitization history information will be assigned the same step numbers, and descriptions will be omitted or simplified. Figure 10 is a flowchart of the process for registering hand bottle information.

For example, while the staff member is logged in to the staff terminal device 4B, they operate the trigger 221 of the hand spray bottle 2B to spray sanitized water onto their hands. When the trigger 221 is operated, a number of beacon signals corresponding to the number of times the trigger 221 is operated (number of sprays) is transmitted from the beacon signal transmitter 23 of the hand spray bottle 2B. As shown in FIG. 10, the beacon signal receiver 43B of the staff terminal device 4B receives beacon signals corresponding to the number of times the trigger 221 is operated (step S51). The information receiver 482B accepts the number of beacon signals received by the beacon signal receiver 43B as the number of sprays of sanitized water.

The sterilization management unit 488B identifies the hand bottle information corresponding to the hand spray bottle 2B being used by the staff member based on the beacon ID corresponding to the beacon signal. Furthermore, the sterilization management unit 488B identifies the bottle basic information based on the bottle ID in the hand bottle information. The sterilization management unit 488B performs steps S34 to S37 based on the hand bottle information and the bottle basic information. When the staff member confirms the warning in step S36 that the remaining amount of sanitized water is low, it is preferable that they replace the sanitized water in the hand spray bottle 2B and perform the hand bottle information registration process.

Next, the warning unit 487B determines whether the expiration date of the sanitary water has expired based on the expiration date and sterilization date and time included in the hand bottle information (step S52). If the warning unit 487B determines that the expiration date of the sanitary water has expired (step S52: YES), it issues a warning to that effect (step S53). When the staff member confirms the warning to the effect that the expiration date has expired in step S53, it is preferable that the staff member replace the sanitary water in the hand spray bottle 2B, perform the hand bottle information registration process, and then sterilize the hands again using the replaced sanitary water.

If the concentration estimation unit 486B determines that the expiration date of the sanitary water has not passed (step S52: NO), or after issuing a warning that the expiration date of the sanitary water has passed (step S53), it estimates the concentration of the sanitary water based on the initial concentration and production date and time of the sanitary water included in the hand bottle information, and the sterilization date and time (step S38). The warning unit 487B identifies the appropriate concentration of the sanitary water based on the purpose included in the bottle basic information corresponding to the hand spray bottle 2B and the appropriate hand concentration information in the terminal DB 46B. The warning unit 487B determines whether the estimated concentration is below the appropriate concentration (step S39). If the warning unit 487B determines that the estimated concentration is below the appropriate concentration (step S39: YES), it issues a warning that the concentration of the sanitary water is too low to be suitable for sterilizing hands (step S40). When the staff member confirms the warning in step S40, after hand sterilization is complete, it is preferable that they replace the sanitized water in the hand spray bottle 2B, perform the hand bottle information registration process, and then sterilize the hands again using the replaced sanitized water.

If it is determined that the estimated concentration of the sanitized water is not less than the appropriate concentration (step S39: NO), or after a warning process indicating that the concentration of the sanitized water is low (step S40) has been performed, the sterilization management unit 488B identifies the user ID at the time of login. The sterilization management unit 488B also identifies the location where the hands were sterilized based on the purpose included in the bottle basic information. The sterilization management unit 488B then generates hand sterilization history information including information representing the user ID of the staff member who performed the sterilization, the bottle ID of the hand spray bottle 2B used for sterilization, the estimated concentration of the sanitized water at the time of sterilization, the expiration date and number of sprays, the sterilization date and time, and the location where the hands were sterilized, and stores (registers) this information in the terminal DB 46B (step S54). The sterilization management unit 488B also transmits the hand sterilization history information to the server device 3 via the communication unit 41B. The server control unit 32 of the server device 3 that has acquired the hand sterilization history information performs a sharing process for the hand sterilization history information.

Note that the processing based on the remaining amount of sanitized water estimation results (steps S35-S37), the processing based on whether the expiration date of the sanitized water has passed (steps S52-S53), and the processing based on the concentration estimation results of the sanitized water (steps S39-S40) were performed in the order indicated, but the order of these processing steps may be reversed, or at least one of these processing steps may be performed in another processing flow rather than in the hand sanitization history information registration process.

Next, we will explain the sterilization check process based on the sterilization plan information.

In the logged-in state, the warning unit 487B of the staff terminal device 4B determines whether the staff member sterilized items based on the sterilization plan information at the date and time based on the sterilization plan information, based on the user ID at the time of login and the sterilization plan information and item sterilization history information in the terminal DB 46B. The sterilization management unit 488B issues a warning if it determines that the staff member has not sterilized items based on the sterilization plan information. The warning unit 487B also determines whether the staff member has sprayed sanitized water the appropriate number of times, based on the item sterilization history information and item information in the terminal DB 46B. The warning unit 487B issues a warning if it determines that the staff member has not sprayed sanitized water the appropriate number of times.

Next, the display process for sterilization-related information will be explained with reference to the drawings. Figure 11A is a schematic diagram showing the general configuration of the sterilization history selection screen. Figure 11B is a schematic diagram showing the general configuration of the sterilization history screen.

For example, the sterilization management unit 488 of the user terminal device 4 can display information included in the item sterilization history information or hand sterilization history information on the touch panel 45 based on the user's operation of the touch panel 45. For example, the sterilization management unit 488 displays the sterilization history selection screen 530 shown in FIG. 11A on the touch panel 45 based on the item sterilization history information. A calendar is displayed on the sterilization history selection screen 530. When the user selects a specific date (e.g., September 30th), the sterilization management unit 488 displays the sterilization history screen 540 shown in FIG. 11B on the touch panel 45. The sterilization history screen 540 displays the cleaning location based on the item ID, the sterilization completion time, the expiration date and estimated concentration of the sanitized water, and notes in list format. Furthermore, the sterilization management unit 488 displays screens similar to the sterilization history selection screen 530 and the sterilization history screen 540 on the touch panel 45 based on the hand sterilization history information. The sterilization management unit 488 may also display the initial concentration of sanitized water on the sterilization history screen 540. The configurations of the sterilization history selection screen 530 and the sterilization history screen 540 described above are merely examples, and other configurations may be used as appropriate. For example, the sterilization history screen 540 may display the sterilization history on a schematic store map. In this case, the store map may be configured to be configurable for each store type, or may be configured to be configurable to suit the actual store. Furthermore, the sterilization history screen 540 may display a comment such as "Sweeping was also performed" as the sterilization implementation details.

The item sterilization history information and hand sterilization history information (sterilization history information) displayed (presented) in this manner contains the sterilization target and the sterilization implementation details in association with each other. Therefore, by checking the displayed sterilization history information, the user can determine whether the sterilization target has been properly sterilized. In particular, the expiration date and estimated concentration of the sanitized water included in the sterilization implementation details are based on information obtained from the bottle tag G2 of the spray bottle 2, so the staff in charge of sterilization do not need to input the sterilization implementation details. Furthermore, while there is a risk of input errors when staff input the sterilization implementation details, the sterilization implementation details can be identified based on information obtained from the bottle tag G2, allowing the user to accurately grasp the sterilization implementation status.

Since the sterilization history information includes the expiration date of the sanitized water, users can manage the expiration date of the sanitized water used for sterilization and, if necessary, replace sanitized water that is close to its expiration date.

Since the sterilization history information includes the estimated concentration of sanitized water used when sterilization was performed, the user can determine whether sterilization was performed using sanitized water of an appropriate concentration. Furthermore, the user can manage the concentration of the sanitized water used for sterilization and, as necessary, replace sanitized water with a lower concentration. This concentration estimation is particularly important for performing appropriate sterilization with electrolyzed water such as carbonated electrolyzed hypochlorous water or electrolyzed hypochlorous water, whose concentration decreases over time and whose sterilizing power declines. For example, if a store uses one spray bottle 2, as long as the sterilization history information includes at least the estimated concentration of sanitized water, it can determine whether sterilization was performed using sanitized water of an appropriate concentration.

Because the sterilization history information includes the bottle ID, users can easily identify spray bottles 2 that contain sanitized water that is close to its expiration date or that has a low concentration, and can replace the sanitized water in the spray bottles 2 as needed. This allows users to reduce the risk of sterilization being performed using sanitized water that has expired or is too low in concentration, and allows for appropriate hygiene management.

The sterilization history information includes the number of times sanitized water has been sprayed, allowing users to manage the amount of sanitized water used for sterilization.

[Modification of the embodiment]
It goes without saying that the present disclosure is not limited to the embodiments described above, and various modifications can be made without departing from the spirit of the present disclosure. Furthermore, the above embodiments and the modifications described below may be combined in any way as long as they function properly.

For example, while the hygiene management system has been exemplified as managing the sterilization status of items sterilized by staff, it is also possible to place an item spray bottle 2A on each table T and manage the sterilization status of the table T by customers using the item spray bottle 2A. In this case, for example, table bottle information related to the item spray bottle 2A for the table T is shared between the server device 3 and the user terminal device 4. The table bottle information includes information representing the item ID of the table T, the bottle ID of the item spray bottle 2A, and the beacon ID of the spray unit 22. The sterilization management unit 488 of the user terminal device 4 closest to the table T then identifies the number of sprays of sanitized water and the table bottle information corresponding to the item spray bottle 2A used by the customer based on the beacon signal transmitted when the customer operates the trigger 221 of the item spray bottle 2A. The sterilization management unit 488 may generate item sterilization history information including information indicating the item ID of table T, the bottle ID of the item spray bottle 2A used for sterilization, the number of sprays of sanitized water, and the sterilization date and time, and may perform a sharing process in addition to registering this information in the terminal DB 46. Furthermore, the expiration date and estimated concentration of the sanitized water may also be included in the item sterilization history information.

While the hand sanitization history information registration process using hand bottle information and toilet hand bottle information has been exemplified, the hand sanitization history information registration process may also be performed without using this pre-registered bottle information. For example, when registering hand sanitization history information, the sanitization management unit 488B of the staff terminal device 4B identifies the number of sanitized water sprays when, in a logged-in state, the staff member presses the hand sanitization button displayed on the touch panel 45B and then operates the trigger 221 of the hand spray bottle 2B. Hand sanitization history information including information indicating the user ID of the staff member who performed the sanitization, the number of sanitized water sprays, the sanitization date and time, and the fact that the hands were sanitized in a location other than the toilet may be generated and registered in the terminal DB 46B, along with a sharing process. Furthermore, the expiration date and estimated concentration of the sanitized water may also be included in the hand sanitization history information.

Instead of the item tag G1, a two-dimensional code such as a barcode or QR code (registered trademark) may be applied, and a two-dimensional code reader may be placed on the user terminal device 4, and the item to be sterilized may be identified based on the two-dimensional code read by the two-dimensional code reader.

A GPS receiver that receives GPS (Global Positioning System) signals may be placed in the user terminal device 4, and the GPS signals may be used instead of the item tag G1 to identify the item to be sterilized. For example, the location information of a table T, which is an example of an item to be sterilized, may be shared in advance between the server device 3 and the user terminal device 4. When sterilizing an item, for example, the sterilization management unit 488B of the staff terminal device 4B may identify the item that the staff member is sterilizing based on the GPS signal received by the GPS receiver when sanitized water is sprayed.

For example, three beacon signal transmitters may be placed in the dining area, and beacon signals may be used instead of item tags G1 to identify items to be sterilized. For example, the distances from table T, an example of an item to be sterilized, to the three beacon signal transmitters may be shared in advance between the server device 3 and the user terminal device 4. When sterilizing items, for example, the sterilization management unit 488B of the staff terminal device 4B may identify the items that the staff is sterilizing based on the beacon signals from the three beacon signal transmitters received by the beacon signal receiving unit 43B.

For example, an imaging device may be placed in the dining area, and the images captured by the imaging device installed in the dining area may be used instead of the item tag G1 to identify the items to be sterilized. For example, the sterilization management unit 488B of the staff terminal device 4B may use image recognition to identify the items that the staff is sterilizing, based on the images captured by the imaging device when sanitized water is sprayed. Furthermore, the staff member performing the sterilization may also be identified using image recognition.

Although the configuration in which sterilization information is shared between the server device 3 and the user terminal device 4 has been exemplified, it may also be managed centrally by the server device 3 (or stored only in the server device 3). In this case, the server control unit 32 of the server device 3 may function as a hygiene management device, and at least item sterilization history information or hand sterilization history information may be generated based on information read by the reading unit 42 of the user terminal device 4 and beacon signals received by the beacon signal receiving unit 43. The hygiene management system may not include the server device 3. In this case, sterilization information may be managed centrally by the administrator terminal device 4A (or stored only in the administrator terminal device 4A), or may be shared between the administrator terminal device 4A and the staff terminal device 4B. The hygiene management system may not include the server device 3 and the administrator terminal device 4A. In this case, the hygiene management system may include one or more staff terminal devices 4B. If multiple staff terminal devices 4B are included in the hygiene management system, information about sterilization generated by one staff terminal device 4B may be shared among all staff terminal devices 4B.

At least one of the server device 3, administrator terminal device 4A, and staff terminal device 4B may be provided with a function to upload the sterilization status or sterilization evaluation based on at least one of the item sterilization history information and hand sterilization history information to an online website that introduces restaurants.

The sterilization status of each table T may be displayed on the entrance terminal device 5 and the table terminal device 6. For example, if the item tag G1 of a table T is read by the staff terminal device 4B in step S31 of the item sterilization history information registration process, the sterilization management unit 488B may display on the entrance terminal device 5 or the table terminal device 6 that the table T is being sterilized (cleaned). Also, if the item tag G1 of a table T is read again by the staff terminal device 4B in step S41, the sterilization management unit 488B may display on the entrance terminal device 5 or the table terminal device 6 that the sterilization (cleaning) of the table T has been completed.

The sterilization management unit 488 may not include at least one of the number of sprays of sanitized water, expiration date, and estimated concentration in at least one of the item sterilization history information and hand sterilization history information, or may include information indicating the initial concentration instead of the estimated concentration. If information indicating the initial concentration is included instead of the estimated concentration, the warning unit 487 may issue a warning if the initial concentration of the sanitized water is less than the appropriate concentration, as in the above embodiment. The sterilization management unit 488 may not generate item sterilization history information or hand sterilization history information. The sterilization management unit 488 may not perform processing to determine whether the estimated concentration of the sanitized water is less than the appropriate concentration. The sterilization management unit 488 may manage the pH of the sanitized water instead of or in addition to the concentration of the active ingredient in the sanitized water. The user terminal device 4 may not be provided with a function to manage the remaining amount of sanitized water.

For example, if, during the registration process of item sterilization history information, the estimated concentration of sanitized water is less than the appropriate concentration for a specific item but is equal to or greater than the appropriate concentration for another item, the warning unit 487 may not issue a warning, but may instead notify the user that the sanitized water is not suitable for sterilizing the specific item but can be used to sterilize the other item. While a configuration in which the appropriate concentration varies depending on the type of sterilization target (type of item, hands) has been exemplified, the appropriate concentration may be the same regardless of the type of sterilization target. In this case, the warning unit 487 may issue a warning if the estimated concentration of sanitized water is less than the appropriate concentration, as in the above embodiment.

Although the example shows a configuration in which the user terminal device 4 acquires parameters indicating the effectiveness of sanitary water set by the sanitary water generating apparatus 1 via the bottle tag G2, it is also possible to acquire the parameters directly from the sanitary water generating apparatus 1, for example, by communicating with the sanitary water generating apparatus 1. In this case, the parameter output unit is configured by the communication unit of the sanitary water generating apparatus 1.

The user terminal device 4 may be provided with a function to display a monitoring screen related to the spray bottles 2. Examples of information displayed on the monitoring screen include the location of each spray bottle 2 within the store, the remaining amount of sanitized water, refill date and time, expiration date, and estimated concentration. The location of each spray bottle 2 within the store may also be represented by displaying an image of the spray bottle 2 on a store map. At least one of the color and size of the image of the spray bottle 2 may be varied depending on whether sterilization using the spray bottle 2 is being performed, whether the remaining amount of sanitized water is equal to or exceeds a threshold amount, whether the expiration date has passed, whether the estimated concentration is below the appropriate concentration, etc.

Carbonated electrolyzed hypochlorous water and electrolyzed hypochlorous water are given as examples of disinfectants, but other disinfectants with disinfecting properties, such as alcohol and sodium hypochlorite, can also be used.

While a spray bottle 2 has been used as an example of a sterilization device, the sterilization device need only have a spray unit that sprays a disinfectant. Therefore, any sterilization device that can bring a disinfectant into contact with an object to be sterilized, such as a device that drips a disinfectant or a device that applies a disinfectant, can be used. In other words, in this disclosure, discharging a disinfectant is a concept that includes applying a disinfectant, dripping a disinfectant, and contacting a disinfectant with an object to be sterilized. The sterilization device may also have the function of wiping disinfectant off an object. The sterilization device may also be configured with only a spray unit 22 equipped with a beacon signal transmitter 23 and a bottle tag G2. In this case, the spray bottle 2 may be configured by attaching the spray unit 22 to a commercially available container (bottle).

This disclosure can be applied to hygiene management devices, hygiene management systems, hygiene management methods, and disinfectant generation devices.
