DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0012] [Embodiment] An embodiment of the present disclosure will be described.

[0013] <Configuration of hygiene management system> First, the configuration of the hygiene management system will be described below. Fig. 1 is a block diagram showing a schematic configuration of the hygiene management system.

[0014] 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 be, for example, elderly housing, accommodation facilities, hospitals, and libraries. The hygiene management system 10 includes a sanitary 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 numbers of the sanitary water generating devices 1, the spray bottles 2, the server device 3, the user terminal devices 4, the entrance terminal devices 5, and the table terminal devices 6 constituting the hygiene management system 10 are not limited to the numbers shown in Fig. 1.

[0015] The sanitary water generating device 1 is an example of a disinfectant generating device, and is arranged, for example, in the kitchen of a restaurant. The sanitary water generating device 1 generates sanitary water to be used for disinfection. The sanitary water is an example of a disinfectant.

[0016] The spray bottle 2 is an example of a sterilization device, and sterilizes the sterilization target by spraying sanitized water onto the sterilization target. Examples of the sterilization target include a table, a chair, a cooking utensil, a toilet, and hands. Examples of cooking utensils to be sterilized include a cutting board, a knife, and a pot. In the following, the spray bottle 2 used to sterilize items other than hands may be referred to as an "item spray bottle 2A". In addition, the spray bottle 2 used to sterilize hands in a place other than a toilet (for example, a break room) may be referred to as a "hand spray bottle 2B". In addition, the spray bottle 2 used to sterilize hands in a toilet may be referred to as a "toilet hand spray bottle 2C". The item spray bottle 2A is carried by, for example, a staff member of a restaurant. The hand spray bottle 2B is placed in a place other than a toilet, such as a kitchen or a staff break room. The toilet hand spray bottle 2C is placed, for example, on a washbasin in a toilet.

[0017] The server device 3 is disposed, for example, outside the restaurant. The server device 3 may be disposed inside the restaurant. The server device 3 is configured to be able to transmit and receive various information between the user terminal device 4, the entrance terminal device 5, and the table terminal device 6 via the communication network N. The server device 3 stores various information related to the sterilization status.

[0018] The user terminal device 4 is an example of a hygiene management device, and is carried by a restaurant manager and staff who move around the eating and drinking space of the restaurant. The user terminal device 4 is used to register various information used for managing the sterilization status in the server device 3, and to check the sterilization status, etc.

[0019] The entrance terminal device 5 is installed at the entrance of the restaurant. The table terminal device 6 is placed on 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 an image and a sound, for example, based on item sterilization history information stored in the server device 3 or the user terminal device 4, which will be described later.

[0020] Also, an item tag G1 composed of, for example, an NFC (Near Field Communication) tag (electronic tag) is attached to each of the items to be sterilized in the restaurant. The items to which the item tag G1 is attached are, for example, a table T, cooking utensils, or a toilet. An item ID unique to each item is recorded in the item tag G1. The item ID is an example of information representing the sterilization target. The item and the store are identified by the item ID. The item ID is read by the user terminal device 4 when the item is sterilized. In addition, in the case of an item to which it is difficult to attach the item tag G1, the item tag G1 may be attached to a wall or another item located near the item. Also, instead of attaching the item tag G1 to each of the multiple items, the item tags G1 of multiple items may be attached together on a single piece of paper, a wall, or the like.

[0021] In addition, a user tag, for example an NFC tag (electronic tag), is attached to the name tag of each of the manager and staff. A user ID unique to the manager or staff is recorded in the user tag. When there is no need to distinguish between the manager and the staff, at least one of the manager and the staff may be referred to as a user.

[0022] Next, each component of the sanitary management system 10 will be described in detail. Fig. 2 is a schematic diagram showing the general configuration of the sanitary water generating device and the spray bottle. Fig. 3 is a block diagram showing the general configuration of the server device. Fig. 4 is a block diagram showing the general configuration of the user terminal device.

[0023] As shown in FIG. 2, the sanitary water generating device 1 includes a generating unit 11, a supplying unit 12, a writing unit 13, a display unit 14, and a generation control unit 15.

[0024] The generating unit 11 generates carbonated electrolytic hypochlorous water as sanitary water, for example, as follows, based on the control of the generation control unit 15. First, the generating unit 11 electrolyzes saturated salt water in a salt water tank in an electrolytic cell, and then mixes it with water to generate electrolytic hypochlorous water. The generating unit 11 generates carbonated electrolytic hypochlorous water by mixing carbon dioxide gas with electrolytic hypochlorous water. The generating unit 11 may be configured with an electrolysis line that electrolyzes saturated salt water 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 electrolytic hypochlorous water. In addition, electrolytic hypochlorous water may be generated by electrolyzing salt water with a low salt concentration that is not saturated salt water, and then mixing it with water, and carbon dioxide gas may be mixed with the generated electrolytic hypochlorous water to generate carbonated electrolytic hypochlorous water. In this case, the salt water with a low salt concentration may be provided in a tank, or may be provided by in-line mixing of saturated salt water and dilution water.

[0025] The effective chlorine concentration (concentration of active ingredients) of the carbonated electrolytic hypochlorous water thus generated is, for example, 25 ppm or more and 200 ppm or less, and the pH is 5 or more and 6.5 or less. In the following, the effective chlorine concentration may be referred to as "concentration". The concentration at the time of generation by the generation unit 11 may be referred to as "initial concentration". Carbonated electrolytic hypochlorous water having such characteristics has a sterilizing power about 80 times that of sodium hypochlorite of the same concentration. In addition, carbonated electrolytic hypochlorous water has a characteristic that the concentration decreases over time and the sterilizing power decreases. In addition, the generation unit 11 can generate electrolytic hypochlorous water that does not contain carbon dioxide. As the electrolytic hypochlorous water, those having a concentration of active ingredients of 40 ppm or more and 200 ppm or less and a pH of 7.5 or more can be exemplified. In the following, carbonated electrolytic hypochlorous water or electrolytic hypochlorous water may be referred to as "sanitary water".

[0026] The supply unit 12 supplies the sanitary water generated by the generation unit 11 to the spray bottle 2.

[0027] The writing unit 13 writes the initial concentration, expiration date, and production date and time of the sanitary water supplied to the spray bottle 2 into a bottle tag G2 of the spray bottle 2, which will be described later, based on the control of the production control unit 15. The initial concentration and expiration date of the sanitary water written into the bottle tag G2 are examples of parameters indicating the effectiveness of the sanitary water at the time of its production. The parameters indicating the effectiveness are an example of the contents of sterilization. The writing unit 13 constitutes a parameter output unit that outputs parameters indicating the effectiveness of the sanitary water.

[0028] The display unit 14 is an example of a notification unit, and displays various types of information based on the control of the generation control unit 15.

[0029] The production control unit 15 associates the initial concentration of the sanitary water, the expiration date, the production date and time, and the management number, and stores them in a memory (not shown). The production control unit 15 causes the display unit 14 to display the expiration date of the sanitary water produced at a specified date and time, based on the operation of an operation unit (not shown). By displaying the expiration date of the sanitary water on the sanitary water generating device 1 in this way, for example, staff can easily know until when the sanitary water can be used, and can perform appropriate hygiene management. The expiration date of the sanitary water may also be notified by sound from the sanitary water generating device 1.

[0030] The spray bottle 2 includes a bottle portion 21, a spray portion 22, and a beacon signal transmission portion 23.

[0031] The bottle portion 21 is an example of a container. Sanitized water is stored in the bottle portion 21. A bottle tag G2 is fixed to the bottle portion 21. The bottle tag G2 is formed of, for example, an NFC tag (electronic tag). A bottle ID unique to the spray bottle 2 is recorded in the bottle tag G2. The bottle ID is an example of information representing the sterilization device. The initial concentration, expiration date, and generation date and time of the sanitized water in the bottle portion 21 are recorded in the bottle tag G2. The spray portion 22 is an example of a discharge portion. The spray portion 22 has a trigger 221 which is an example of an operation portion, and sprays an amount of sanitized water according to the number of times the trigger 221 is operated. The beacon signal transmission portion 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 transmission portion 23 is an example of a transmission portion that outputs information representing the amount of sanitized water used. The beacon signal transmitted from beacon signal transmission unit 23 includes information indicating a beacon ID unique to spray unit 22, which is an identifier unique to the sterilization apparatus.

[0032] Next, a description will be given of the server device 3. As shown in FIG.

[0033] User information corresponding to each user is stored in the server DB 31. The user information includes information indicating the user's name and user ID.

[0034] The server DB31 stores item information corresponding to each item to be sterilized. The item information includes information indicating the name of the item (and location), the item ID, the appropriate number of sprays, and the appropriate concentration. The appropriate number of sprays is the number of sprays of sanitary water required to properly sterilize the item. The appropriate concentration is the concentration of sanitary 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 in toilets is higher than the appropriate concentration in items other than toilets.

[0035] The server DB31 stores appropriate concentration information for hands. The appropriate concentration information for hands includes information indicating the place where the hands are sterilized (the toilet or a place other than the toilet) and an appropriate concentration. The appropriate concentration is the concentration of sanitized water required to properly sterilize the hands. Since the possibility of the presence of viruses such as norovirus in the toilet is higher than in places other than the toilet, it is preferable that the appropriate concentration when sterilizing the hands in the toilet is higher than the appropriate concentration when sterilizing the hands in places other than the toilet.

[0036] The server DB31 stores basic bottle information corresponding to each spray bottle 2 (the spray bottle for objects 2A, the spray bottle for hands 2B, and the spray bottle for toilet hands 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 sanitary water sprayed when the trigger 221 is operated once, the capacity of the bottle part 21, the remaining amount of sanitary water, the warning threshold, the expiration date and generation date and time of the sanitary water, and the purpose. The remaining amount of sanitary water is updated according to the actual remaining amount. The warning threshold is the remaining amount that is the criterion for warning that the remaining amount of sanitary water is low. The purpose indicates that the spray bottle 2 is for sterilizing objects, for sterilizing hands in places other than the toilet, or for sterilizing hands in the toilet.

[0037] The server DB 31 stores the product bottle information related to the product spray bottle 2A. The product bottle information includes information representing the user ID of the user who uses the product spray bottle 2A, the bottle ID of the product spray bottle 2A, the expiration date, the initial concentration, and the generation date and time of the sanitary water, and the beacon ID of the spray unit 22.

[0038] The server DB 31 stores hand bottle information related to the hand spray bottle 2B. The hand bottle information includes information indicating the bottle ID of the hand spray bottle 2B, the expiration date, the initial concentration, and the generation date and time of the sanitary water, and the beacon ID of the spray unit 22.

[0039] The server DB 31 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 generation date and time of the sanitary water, and the beacon ID of the spray unit 22.

[0040] Sterilization plan information is stored in the server DB 31. The sterilization plan information includes information indicating the user ID of the staff member who will perform the sterilization, the item ID of the item to be sterilized, and the sterilization date and time.

[0041] The server DB 31 stores item sterilization history information indicating the implementation 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 when sterilization was performed, the expiration date and number of sprays, and the sterilization date and time.

[0042] The server DB31 stores hand sterilization history information that indicates the implementation status of hand sterilization. The hand sterilization history information includes information that indicates the user ID of the staff member who sterilized the hands, the bottle ID of the spray bottle 2 used for sterilization, the estimated concentration of the sanitary water when sterilization was performed, the expiration date and number of sprays, the date and time of sterilization, and the place where the hands were sterilized. The place where the hands were sterilized is a toilet or a place other than a toilet.

[0043] The user information, the item bottle information, the sterilization plan information, the item sterilization history information, and the hand sterilization history information are associated with each other by the user ID. The bottle basic information, the item bottle information, the hand bottle information, or the toilet hand bottle information, the item sterilization history information, and the hand sterilization history information are associated with each other by the bottle ID. Note that the configuration of each piece of information stored in the server DB31 is merely an example, and other configurations may also be applied.

[0044] When the server control unit 32 acquires the 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, the server control unit 32 stores the information in the server DB 31 and transmits the stored information to the user terminal device 4 that did not generate the information. By such processing of the server control unit 32, the same information is shared between the server device 3 and the user terminal device 4.

[0045] Next, the user terminal device 4 will be described.

[0046] 4 is configured by, 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.

[0047] The communication unit 41 communicates with the server device 3. The reading unit 42 reads information recorded in a user tag, an item tag G1, or a 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 an object to be imaged and generates a captured image. The touch panel 45 has a function as a display unit that displays an image based on the control of the terminal control unit 48, and a function as an operation unit that outputs an operation signal to the terminal control unit 48 according to the contact state of a finger or the like on the touch panel 45.

[0048] 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 storage unit 47 stores various information necessary for the operation of the user terminal device 4.

[0049] The terminal control unit 48 has a CPU (Central Processing Unit), and realizes the functions of the terminal control unit 48 by the CPU executing a hygiene management program stored in the terminal storage unit 47. The terminal control unit 48 includes an authentication unit 481, an information receiving unit 482, an appropriate number of injections setting unit 483, an appropriate concentration setting unit 484, a remaining amount estimating unit 485, a concentration estimating unit 486, a warning unit 487, and a sterilization management unit 488.

[0050] 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.

[0051] The information receiving unit 482 acquires information read from each tag by the reading unit 42. The information receiving unit 482 receives a user ID recorded in a user tag. The information receiving unit 482 is an example of a target information receiving unit that receives an item ID recorded in an item tag G1. The information receiving unit 482 is an example of a device information receiving unit that receives a bottle ID recorded in a 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 sanitary 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 a beacon signal is received by the beacon signal receiving unit 43 as the amount of sanitary water used during sterilization.

[0052] The appropriate number of sprays setting unit 483 sets an appropriate number of sprays of sanitary water for each sterilization target.

[0053] The appropriate concentration setting unit 484 sets an appropriate concentration of sanitary water for each sterilization target.

[0054] The remaining amount estimation unit 485 estimates the remaining amount of sanitary water in the spray bottle 2 when sterilization with the sanitary water is performed.

[0055] The concentration estimation unit 486 estimates the concentration of sanitary water when sterilization with sanitary water is performed.

[0056] The warning unit 487 issues various warnings during sterilization.

[0057] The sterilization management unit 488 generates item sterilization history information and hand sterilization history information, and performs processing to store the information 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.

[0058] The detailed processes performed by the appropriate injection count setting unit 483, appropriate concentration setting unit 484, remaining amount estimating unit 485, concentration estimating unit 486, warning unit 487, and sterilization management unit 488 will be described later. In the following, the user terminal device 4 carried by the manager may be referred to as the manager terminal device 4A. The user terminal device 4 carried by the staff may be referred to as the staff terminal device 4B.

[0059] <Operation of the hygiene management system> Next, the operation of the hygiene management system will be described. Note that the procedures of various processes shown below are only examples, and other procedures may be applied. In addition, the following describes a case where the administrator terminal device 4A is used to perform the registration process of user information, item information, appropriate concentration information for hands, basic bottle information, and sterilization plan information, but the registration process of the above-mentioned information may also be performed using the staff terminal device 4B.

[0060] <User information registration process> First, the user information registration process will be described.

[0061] When the administrator starts using the hygiene management system 10, the administrator performs a registration process of the administrator's own user information. The sterilization management unit 488 (hereinafter, may be referred to as the "sterilization management unit 488A") of the terminal control unit 48 (hereinafter, may be 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, may be referred to as the "touch panel 45A") of the administrator terminal device 4A. The administrator performs an input operation of 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, may be referred to as the "terminal DB 46A") of the administrator terminal device 4A, while transmitting the generated user information to the server device 3 via the communication unit 41 (hereinafter, may be 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 manager also performs the same operation as the registration process of his / her own user information to store the user information of each staff member in the server DB 31. The manager also uses a writing device (not shown) to record the user ID in the user tag of the user's name tag.

[0062] After the above user information registration process is completed, when the user holds his / her 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 process is performed based on the user ID read by the reading units 42A, 42B, and the server device 3 and the manager terminal device 4A or staff terminal device 4B enter a state (login state) in which various information can be sent and received between the server device 3 and 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 transmits 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").

[0063] <Product information registration process> Next, the registration process of the item information will be described. The registration process of the item information 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. In addition, the administrator records the item ID in the item tag G1 using a writing device not shown, and then attaches the item tag G1 to the item.

[0064] The appropriate number of sprays setting unit 483 (hereinafter, sometimes referred to as "appropriate number of sprays setting unit 483A") of the manager terminal device 4A calculates the area of ​​the sterilization site of the article based on the captured image generated by the imaging unit 44A. The appropriate number of sprays setting unit 483A determines the appropriate number of sprays of sanitary water based on, for example, information indicating 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 larger number as the area of ​​the sterilization site becomes larger. The appropriate number of sprays setting unit 483A may determine the appropriate number of sprays based on information indicating the relationship between the sterilization site and the appropriate number of sprays. The appropriate number of sprays setting unit 483A may also determine the appropriate number of sprays based on, for example, information indicating the relationship between the name of the article and the appropriate number of sprays input by operating the touch panel 45A.

[0065] Furthermore, the appropriate concentration setting unit 484 of the manager terminal device 4A determines the appropriate concentration of sanitary water for the 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 sanitary water. The appropriate concentration is set to a higher concentration for an item that requires stronger sterilization. For example, the appropriate concentration for a table T is set to 100 ppm, and the appropriate concentration for a toilet is set to 200 ppm.

[0066] The sterilization management unit 488A generates product information indicating the name of the product, the product ID, the appropriate number of sprays, and the appropriate concentration. The sterilization management unit 488A stores the generated product information in the terminal DB 46A, while transmitting it to the server device 3 via the communication unit 41A. At least one of the appropriate number of sprays and the appropriate concentration may be set to a value based on the operation of the touch panel 45A by the administrator. The administrator may be allowed to set the appropriate concentration to an arbitrary concentration. With this configuration, when the rate of decrease in the concentration of the sanitary water per unit time differs depending on the storage environment or use environment of the spray bottle 2, the administrator can set an appropriate appropriate concentration according to the storage environment or use environment of the spray bottle 2. The appropriate concentration setting unit 484 may set the appropriate concentration based on factors that affect the rate of decrease in the concentration of the sanitary water per unit time, such as the temperature during storage or use of the spray bottle 2, whether the storage place or use place of the spray bottle 2 is indoors or not, and the material of the bottle part 21, which are set by the administrator.

[0067] When the server control unit 32 of the server device 3 acquires the item information, it stores the information in the server DB 31, and transmits the information to the staff terminal device 4B that does 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) that acquires the item information via the communication unit 41 (hereinafter, sometimes referred to as the communication unit 41B) of the staff terminal device 4B 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. In the following, the process of sharing the 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 is referred to as the sharing process. In the following, a detailed description of the sharing process is omitted.

[0068] <Registration process of appropriate concentration information for hands> Next, the registration process of the appropriate concentration information for hands 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 of the appropriate concentration information for hands based on the administrator's operation of the touch panel 45A. The administrator performs an input operation of the sterilization location for hands (toilet or a place other than the toilet) and the appropriate concentration based on the contents of the registration screen. The sterilization management unit 488A generates appropriate concentration information for hands based on the information based on the input operation, stores it 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 that has acquired the appropriate concentration information for hands performs a sharing process of the appropriate concentration information for hands.

[0069] <Registering basic bottle information> Next, the registration process of the bottle basic information will be described. The registration process of the bottle basic information is performed, for example, when starting to use a new spray bottle 2. For example, the sterilization management unit 488A of the administrator terminal device 4A displays a registration screen of the bottle basic information based on the administrator's operation of the touch panel 45A in a logged-in state. Based on the contents of the registration screen, the administrator performs an input operation of the name of the spray bottle 2, the bottle ID, the spray amount of sanitary water when the trigger 221 is operated once, the capacity of the bottle part 21, the remaining amount of sanitary water (no remaining amount), the warning threshold value, and the purpose. In addition, the administrator holds up the bottle tag G2 of the spray bottle 2A for the item to be registered to the reading unit 42A. When the bottle tag G2 is read by the reading unit 42A, the information receiving unit 482 (hereinafter, sometimes referred to as the "information receiving unit 482A") receives the expiration date and the generation date and time recorded in the bottle tag G2. In addition, the administrator records the bottle ID in the bottle tag G2 using a writing device not shown, and then attaches the bottle tag G2 to the spray bottle 2.

[0070] The sterilization management unit 488A generates the bottle basic information based on the information based on the input operation and the expiration date and the generation date and time of the sanitary water received from the bottle tag G2. The spray bottle 2 may be provided with a communication function, and the sterilization management unit 488A may acquire the expiration date and the generation date and time of the sanitary 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 the generation date and time of the sanitary 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 the generation date and time of the sanitary water may be added to the bottle basic information in the registration process of the bottle information for items, the bottle information for hands, or the bottle information for toilet hands, which will be described later. The sterilization management unit 488A stores the generated bottle basic information in the terminal DB 46A, while transmitting it to the server device 3 via the communication unit 41A. The server control unit 32 of the server device 3 that has acquired the bottle basic information performs a sharing process of the bottle basic information. In addition, if the bottle basic information shared at this stage is configured not to include the expiration date and production date and time of the sanitary water, the server control unit 32 may obtain the expiration date and production date and time of the sanitary water from the production control unit 15 of the spray bottle 2 and register them in the bottle basic information.

[0071] <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 schematic configuration of a sterilization plan registration screen. Fig. 5B is a schematic diagram showing the schematic configuration of a sterilization plan screen. Fig. 5C is a schematic diagram showing the schematic configuration of a sterilization check plan screen.

[0072] For example, in a logged-in state, the sterilization management unit 488 of the manager terminal device 4A displays the sterilization plan registration screen 500 shown in Fig. 5A based on the manager's operation of the touch panel 45A. The manager 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 sterilization), and then operates the register button 502.

[0073] The sterilization management unit 488A acquires information based on the input operation and generates a sterilization plan. Then, the sterilization management unit 288A displays a 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 the cleaning location based on the item ID, the sterilization date and time, and the person in charge based on the user ID in list format. 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 operation of the touch panel 45A by the manager, and displays the sterilization check plan screen 520 shown in FIG. 5C. The sterilization check plan screen 520 displays the cleaning location based on the item ID, the scheduled time period (the time period to be checked), and remarks in list format. For example, a comment such as "There is dirt on the table that cannot be removed" can be registered in the remarks. The sterilization management unit 488A stores the generated sterilization plan in the terminal DB 46A as sterilization plan information, while transmitting 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, the sterilization plan screen 510, and the sterilization check plan screen 520 described above are merely examples, and other configurations may be used as appropriate.

[0074] <Registration process of bottle information for goods> Next, the registration process of the product bottle information will be described with reference to the drawings. The registration process of the product bottle information is performed, for example, before sterilizing the product using the product spray bottle 2A. When one staff member uses the same product spray bottle 2A all day, the registration process of the product bottle information related to the product spray bottle 2A may be performed once a day. On the other hand, when one staff member uses different product spray bottles 2A as needed, the registration process of the product bottle information related to each product spray bottle 2A may be performed. FIG. 6 is a flowchart of the registration process of the product bottle information.

[0075] For example, in a logged-in state, the sterilization management unit 488B of the staff terminal device 4B displays a registration screen for item 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 his / her name tag over the reading unit 42B of the staff terminal device 4B, and then holds the bottle tag G2 of the item spray bottle 2A to be registered over the reading unit 42B.

[0076] 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 in the bottle tag G2. The sterilization management unit 488B may display the expiration date of the sanitary water in the item spray bottle 2A on the touch panel 45B. By displaying the expiration date of the sanitary water on the touch panel 45B, the staff can easily recognize until when the sanitary water can be used, and can perform appropriate sanitary management.

[0077] Then, the sterilization management unit 488B identifies the bottle basic information corresponding to the product spray bottle 2A to be registered from among 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 judges whether the date and time of generation of the sanitary water acquired by the information receiving unit 482B is the same as the date and time of generation of the sanitary water included in the bottle basic information corresponding to the product spray bottle 2A to be registered (step S3). In step S3, it is judged that the date and time of generation of the sanitary water acquired by the information receiving unit 482B is the same as the date and time of generation of the sanitary water included in the bottle basic information when the sanitary water in the product spray bottle 2A has not been replaced, and the remaining amount of the sanitary water is the same as the amount after the previous sterilization. On the other hand, it is judged that the date and time of generation of the sanitary water acquired by the information receiving unit 482B is different from the date and time of generation of the sanitary water included in the bottle basic information when the sanitary water in the product spray bottle 2A has not been replaced.

[0078] When the sterilization management unit 488B determines that the generation date and time acquired by the information receiving unit 482 is different from the generation date and time included in the bottle basic information (step S3: NO), it updates the expiration date and generation date and time of the sanitary water included in the bottle basic information (step S4). Specifically, the sterilization management unit 488B updates the expiration date and generation date and time of the sanitary water included in the bottle basic information of the terminal DB 46B to the expiration date and generation date and time of the sanitary water acquired by the information receiving unit 482, and updates the remaining amount of sanitary water included in the bottle basic information to the capacity value of the bottle unit 21 included in the bottle basic information. Thereafter, the sterilization management unit 488B 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 has acquired the bottle basic information performs a sharing process for the bottle basic information.

[0079] When it is determined that the sanitary water generation date and time acquired by the information receiving unit 482B is the same as the sanitary water generation date and time of the bottle basic information (step S3: YES), or after the update process of the bottle basic information (step S4) is performed, the warning unit 487 of the staff terminal device 4B (hereinafter, may be referred to as the "warning unit 487B") determines whether the expiration date of the sanitary water has expired based on the expiration date acquired from the bottle tag G2 and the date and time of reading the bottle tag G2 (step S5). When it is determined that the expiration date of the sanitary water has expired (step S5: YES), the warning unit 487B 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 issue a warning sound from an audio output unit (not shown). The warning in the process described below may be a display or a sound.

[0080] In this way, the validity of the sanitary water is managed based on the expiration date of the sanitary water obtained from the bottle tag G2, i.e., the expiration date output from the sanitary water generating device 1, so the staff does not need to set the expiration date. Also, when the staff enters the expiration date, there is a risk of inputting an incorrect date, but since the validity of the sanitary water is managed based on the expiration date obtained from the bottle tag G2, the staff can properly manage hygiene. In particular, if the validity of the sanitary water has expired, a warning is issued by the staff terminal device 4B, so the staff can stop using the sanitary water and can more properly manage hygiene.

[0081] When the warning process of step S6 is performed, the sterilization management unit 488B ends the registration process without generating item bottle information. Information indicating that the expiration date has passed may be recorded in the bottle tag G2 of the item spray bottle 2A for which the warning has been 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 in the bottle tag G2. Also, the user terminal device 4 may be provided with a function for recording information in 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 in the bottle tag G2.

[0082] On the other hand, when the sterilization management unit 488B determines that the expiration date of the sanitary water has not passed (step S5: NO), it displays a screen on the touch panel 45B that prompts the staff member to operate the trigger 221 of the spray bottle for goods 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 spray bottle for goods 2A (step S7). The sterilization management unit 488B generates bottle information for goods including information representing the user ID, the bottle ID of the spray bottle for goods 2A, the expiration date, initial concentration, and generation date and time of the sanitary water, and the beacon ID based on the beacon signal, and stores (registers) the bottle information in the terminal DB 46B (step S8). In addition, the sterilization management unit 488B transmits the bottle information for goods to the server device 3 via the communication unit 41B. The server control unit 32 of the server device 3 that has acquired the bottle information for goods performs a sharing process for the bottle information for goods. In addition, in 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 of the registration process based on the initial concentration of the sanitized water recorded in the bottle tag G2 and the date and time of the registration process of the item bottle information.

[0083] <Registration process of hand bottle information and toilet hand bottle information> Next, the registration process of the hand bottle information and the toilet hand bottle information will be described with reference to the drawings. The registration process of 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 of the toilet hand bottle information is also performed at the same timing as the registration process of the hand bottle information. Since the registration processes of the hand bottle information and the toilet hand bottle information are the same, the registration process of the hand bottle information will be described. Furthermore, the same step numbers are assigned to processes similar to the registration process of the item bottle information, and the description will be omitted or simplified. FIG. 7 is a flowchart of the registration process of the hand bottle information.

[0084] For example, 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 in a logged-in state. 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.

[0085] As shown in FIG. 7, the reading unit 42A of the manager terminal device 4A reads the bottle tag G2 of the hand spray bottle 2B (step S21). Next, the information receiving unit 482A of the manager terminal device 4A receives the bottle ID, expiration date, and creation date and time recorded in the bottle tag G2. Then, the sterilization management unit 488A identifies the bottle basic information corresponding to the hand spray bottle 2B to be registered from the bottle basic information of 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 sanitary water to the identified bottle basic information (step S4). After that, the sterilization management unit 488A 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 that has acquired the bottle basic information performs a sharing process of the bottle basic information.

[0086] After performing the bottle basic information update process (step S4), the sterilization management unit 488A displays a screen on the touch panel 45A that prompts the user 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 and time of the sanitary water, and the beacon ID based on the beacon signal, and stores (registers) the 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 that has acquired the hand bottle information performs a sharing process of the hand bottle information.

[0087] <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 every 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 from the date and time of generation of sanitized water.

[0088] 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's operation of the touch panel 45B. Based on the contents of the registration screen, the staff 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). Then, the information receiving unit 482B receives the item ID recorded in the item tag G1. The sterilization management unit 488B also displays the appropriate number of sprays of the item to be sterilized on the touch panel 45B (step S32). In the process of step S32, the sterilization management unit 488B identifies item information corresponding to the item to be sterilized from among 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 the item, the staff can easily recognize the appropriate number of sprays of sanitary 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.

[0089] Next, the staff 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 operates the trigger 221 a suitable number of times or more for spraying. When the trigger 221 is operated, a number of beacon signals corresponding to the number of operations (number of sprays) are transmitted from the beacon signal transmitting unit 23 of the item spray bottle 2A. The beacon signal receiving unit 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 accepting unit 482B accepts the number of times the beacon signal is received by the beacon signal receiving unit 43B as the number of sprays of sanitized water.

[0090] The sterilization management unit 488B identifies the item bottle information corresponding to the item spray bottle 2A used by the staff from among the item bottle information in the terminal DB46B based on the user ID at the time of login. The sterilization management unit 488B may identify the item bottle information corresponding to the item spray bottle 2A used by the staff 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 among the bottle basic information in the terminal DB46B based on the item ID included in the identified item bottle information. Then, the remaining amount estimation unit 485 (hereinafter, sometimes referred to as the "remaining amount estimation unit 485B") of the staff terminal device 4B estimates the remaining amount of sanitary water in the item spray bottle 2A based on the identified bottle basic information (step S34). In the process of step S34, the remaining amount estimation unit 485B calculates the amount of sanitary water sprayed during sterilization based on the amount of sanitary 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, remaining amount estimating unit 485B subtracts the calculated spray amount from the remaining amount of sanitary water included in the bottle basic information to estimate the remaining amount of sanitary water after spraying.

[0091] The warning unit 487B judges whether the estimated remaining amount of sanitary water (estimated remaining amount) is less than the warning threshold included in the bottle basic information (step S35). When the warning unit 487B judges that the estimated remaining amount is less than the warning threshold (step S35: YES), it issues a warning that the remaining amount of sanitary water is low (step S36). When the staff confirms the warning in step S35, it is preferable that after sterilization of the item is completed, the staff replaces the sanitary 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 sanitary water in the item spray bottle 2A is low, the staff can easily recognize the time to replace the sanitary water. Such a warning is particularly effective when the inside of the bottle portion 21 cannot be seen.

[0092] 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 a warning process is performed to the effect that the remaining amount of sanitary water is low (step S36), the sterilization management unit 488B updates the remaining amount of sanitary water included in the bottle basic information of the terminal DB 46B to the remaining amount estimated in step S34 (step S37). After this, the concentration estimation unit 486 of the staff terminal device 4B (hereinafter, may be referred to as the "concentration estimation unit 486B") estimates the concentration of sanitary water based on the initial concentration and generation date and time of sanitary water included in the item bottle information and the sterilization date and time (the reception date and time of the beacon signal) (step S38). The concentration estimation unit 486 estimates the concentration of sanitary water based on a relationship such that, for example, the longer the period that has elapsed since the generation date and time, the higher the rate of decrease in concentration from the initial concentration. For example, as shown in FIG. 9, the concentration of sanitary water decreases approximately linearly with the passage of time. FIG. 9 shows that the concentration of sanitary water for which the period elapsed from the generation date and time is less than period A is equal to or greater than the appropriate concentration for a toilet, and therefore the sanitary water can be used to disinfect the toilet and the table. FIG. 9 also shows that the concentration of sanitary water for which the period elapsed from the generation date and time is more than period A and less than period B is less than the appropriate concentration for a toilet and equal to or greater than the appropriate concentration for a table, and therefore the sanitary water cannot be used to disinfect the toilet but can be used to disinfect the table. FIG. 9 also shows that the concentration of sanitary water for which the period elapsed from the generation date and time is more than period B is less than the appropriate concentration for the toilet and the table, and therefore the sanitary water cannot be used to disinfect the toilet and the table. Note that a screen like the one shown in FIG. 9 may be displayed on the touch panel 45B as a screen showing the state (concentration) of the disinfectant liquid in the spray bottle 2.

[0093] The warning unit 487B judges whether the estimated concentration of the sanitary water (estimated concentration) is less than the appropriate concentration included in the item information (step S39). When the warning unit 487B judges that the estimated concentration is less than the appropriate concentration (step S39: YES), it issues a warning that the concentration of the sanitary water is too low to be suitable for sterilization of the item (step S40). When the staff confirms the warning in step S40, after sterilization of the item is completed, it is preferable to replace the sanitary water in the item spray bottle 2A, perform the registration process of the item bottle information, and sterilize the item again using the replaced sanitary water. In this way, a warning that the estimated concentration of the sanitary water is low is issued based on the initial concentration of the sanitary water included in the item bottle information, that is, based on the initial concentration output from the sanitary water generating device 1, so that the staff can easily recognize that sterilization has not been performed using sanitary water of an appropriate concentration, and can appropriately perform hygiene management. In particular, since the appropriate concentration differs for each type of item, the staff can easily recognize that sterilization has not been performed using sanitary water of an appropriate concentration for each type of item.

[0094] When the staff member sterilizes the item by wiping off the sanitary water sprayed on the item with a cloth or the like, he / she again holds 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 process of step S41 is performed when it is determined that the estimated concentration of the sanitary water is not less than the appropriate concentration (step S39: NO) or after a warning process that the concentration of the sanitary water is low (step S40) is performed. Then, the information receiving unit 482B receives the item ID recorded in the item tag G1. After that, the sterilization management unit 488B 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 sanitary water at the time of sterilization, and the sterilization date and time, and stores (registers) the information in the terminal DB 46B (step S42). Furthermore, 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 of the item sterilization history information.

[0095] Note that the sterilization management unit 488B may generate item sterilization history information if the estimated concentration of the sanitary water is determined to be not less than the appropriate concentration (step S39: NO) without reading the item tag G1 in step S41, or after the process of step S40 has been performed. Also, although the process based on the remaining amount of sanitary water estimation result (steps S35-S37) is performed followed by the process based on the concentration estimation result of the sanitary water (steps S39-S40), these processes may be performed in the reverse order, or one of these processes may not be performed in the registration process of the item sterilization history information but may be performed in another processing flow.

[0096] <Hand sanitization history information registration process> Next, the registration process of hand sterilization history information will be described with reference to the drawings. The registration process of hand sterilization history information is performed every time the user's hands are sterilized. Note that the registration process of hand sterilization history information when sterilizing hands in a toilet and when sterilizing hands in a place other than the toilet is the same, so the registration process of hand sterilization history information when sterilizing hands in a place other than the toilet will be described. In addition, the same step numbers are assigned to processes similar to the registration process of item sterilization history information, and the description will be omitted or simplified. FIG. 10 is a flowchart of the registration process of hand bottle information.

[0097] For example, when the staff member is logged in to the staff terminal device 4B, the staff member operates the trigger 221 of the hand spray bottle 2B to spray sanitary water onto his / her own hands. When the trigger 221 is operated, a number of beacon signals corresponding to the number of operations (number of sprays) are transmitted from the beacon signal transmitting unit 23 of the hand spray bottle 2B. As shown in FIG. 10, the beacon signal receiving unit 43B of the staff terminal device 4B receives a beacon signal corresponding to the number of operations of the trigger 221 (step S51). The information accepting unit 482B accepts the number of times the beacon signal is received by the beacon signal receiving unit 43B as the number of sprays of sanitary water.

[0098] The sterilization management unit 488B identifies hand bottle information corresponding to the hand spray bottle 2B used by the staff member, based on the beacon ID corresponding to the beacon signal. Furthermore, the sterilization management unit 488B identifies basic bottle information based on the bottle ID of the hand bottle information. The sterilization management unit 488B performs the processes of steps S34 to S37 based on the hand bottle information and the basic bottle information. When the staff member confirms the warning in step S36 that the remaining amount of sanitary water is low, it is preferable that the staff member replaces the sanitary water in the hand spray bottle 2B and performs the process of registering the hand bottle information.

[0099] 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 replaces the sanitary water in the hand spray bottle 2B, performs a process of registering the hand bottle information, and then sterilizes the hands again using the replaced sanitary water.

[0100] When it is determined that the sanitary water has not expired (step S52: NO), or after a warning process is performed to the effect that the sanitary water has expired (step S53), the concentration estimation unit 486B estimates the concentration of the sanitary water based on the initial concentration and generation 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 specifies 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 of the terminal DB 46B. The warning unit 487B determines whether the estimated concentration is less than the appropriate concentration (step S39). When it is determined that the estimated concentration is less than the appropriate concentration (step S39: YES), the warning unit 487B issues a warning that the concentration of the sanitary water is too low to be suitable for sterilization of hands (step S40). When the staff member acknowledges the warning in step S40, after the disinfection of the hands has been completed, it is preferable that the staff member replace the sanitary water in the hand spray bottle 2B, perform the process of registering the hand bottle information, and then disinfect the hands again using the replaced sanitary water.

[0101] When it is determined that the estimated concentration of the sanitary water is not less than the appropriate concentration (step S39: NO), or after a warning process that the concentration of the sanitary water is low (step S40) is performed, the sterilization management unit 488B identifies the user ID at the time of login. Furthermore, the sterilization management unit 488B identifies the location where the sterilization of the hands and fingers was performed based on the purpose included in the bottle basic information. Then, the sterilization management unit 488B generates hand sterilization history information including information indicating the user ID of the staff who performed the sterilization, the bottle ID of the hand spray bottle 2B used for sterilization, the estimated concentration of the sanitary water at the time of sterilization, the expiration date and number of sprays, the sterilization date and time, and the location where the sterilization of the hands and fingers was performed, and stores (registers) the information in the terminal DB 46B (step S54). Furthermore, the sterilization management unit 488B 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 of the hand sterilization history information.

[0102] Although the processing based on the estimation result of the remaining amount of sanitary water (steps S35 to S37), the processing based on whether the expiration date of the sanitary water has expired (steps S52 to S53), and the processing based on the estimation result of the concentration of the sanitary water (steps S39 to S40) were performed in the order given, the order of these processing may be reversed, and at least one of these processing may be performed in another processing flow rather than in the hand sanitization history information registration process.

[0103] <Sterilization check process> Next, the sterilization check process based on the sterilization plan information will be described.

[0104] In a logged-in state, the warning unit 487B of the staff terminal device 4B determines whether the staff member has sterilized the 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. If the sterilization management unit 488B determines that the staff member has not sterilized the items based on the sterilization plan information, it issues a warning. Furthermore, the warning unit 487B determines whether the staff member has sprayed sanitary water the appropriate number of times, based on the item sterilization history information and item information in the terminal DB 46B. If the warning unit 487B determines that the staff member has not sprayed sanitary water the appropriate number of times, it issues a warning.

[0105] Next, the display process for information related to sterilization will be described with reference to the drawings. Fig. 11A is a schematic diagram showing the schematic configuration of a sterilization history selection screen. Fig. 11B is a schematic diagram showing the schematic configuration of a sterilization history screen.

[0106] For example, the sterilization management unit 488 of the user terminal device 4 can display information included in the item sterilization history information or the 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 a 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 (for example, September 30), the sterilization management unit 488 displays a 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 sanitary water, and notes in a list format. In addition, 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 display the initial concentration of the sanitized water on the sterilization history screen 540. The above-described configurations of the sterilization history selection screen 530 and the sterilization history screen 540 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 in-store map. In this case, the in-store map may be configured to be configurable for each store format, or may be configured to be configurable according to the actual store. In addition, the sterilization history screen 540 may display a comment such as "sweeping was also performed" as the implementation details of sterilization.

[0107] The object sterilization history information and hand sterilization history information (sterilization history information) displayed (presented) in this manner include 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 or not the sterilization target has been appropriately sterilized. In particular, the expiration date and estimated concentration of sanitary water included in the sterilization implementation details are based on information acquired from the bottle tag G2 of the spray bottle 2, so the staff in charge of sterilization does not need to input the sterilization implementation details. Furthermore, when the staff inputs the sterilization implementation details, there is a risk of input errors, but since the sterilization implementation details are identified based on information acquired from the bottle tag G2, the user can accurately grasp the sterilization implementation status.

[0108] Since the sterilization history information includes the expiration date of the sanitary water, the user can manage the expiration date of the sanitary water used for sterilization and, if necessary, can replace sanitary water that is close to its expiration date.

[0109] Since the sterilization history information includes the estimated concentration of the sanitary water when sterilization is performed, the user can determine whether sterilization has been performed using sanitary water of an appropriate concentration. In addition, the user can manage the concentration of the sanitary water used for sterilization, and can replace sanitary water with a low concentration as necessary. In particular, for electrolytic water such as carbonated electrolytic hypochlorous water or electrolytic hypochlorous water, whose concentration decreases over time and whose sterilizing power decreases, such concentration estimation is important for performing appropriate sterilization. For example, in the case where a store uses one spray bottle 2, if at least the estimated concentration of the sanitary water is included in the sterilization history information, it can be determined whether sterilization has been performed using sanitary water of an appropriate concentration.

[0110] Since the sterilization history information includes the bottle ID, the user can easily identify the spray bottle 2 that contains sanitized water that is close to its expiration date or sanitized water with a low concentration, and can replace the sanitized water in the spray bottle 2 as necessary. Therefore, the user can reduce the risk of sterilization being performed using sanitized water that has expired or has a too low concentration, and can perform appropriate hygiene management.

[0111] Since the sterilization history information includes the number of times sanitary water has been sprayed, the user can manage the amount of sanitary water used for sterilization.

[0112] [Modification of the embodiment] Needless to say, 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 shown below may be combined in any way as long as they function normally.

[0113] For example, the sanitary management system has been described as managing the sterilization status of items performed by staff, but an item spray bottle 2A may be placed on each table T to 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 located closest to the table T identifies the number of sprays of sanitary water and the table bottle information corresponding to the item spray bottle 2A used by the customer based on a 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 the table T, the bottle ID of the item spray bottle 2A used for sterilization, the number of sprays of sanitary water, and the sterilization date and time, and may perform a sharing process as well as a process of registering the information in the terminal DB 46. Note that, further, a process may be performed to include the expiration date and estimated concentration of the sanitary water in the item sterilization history information.

[0114] Although the hand sterilization history information registration process using the hand bottle information and the toilet hand bottle information has been exemplified, the hand sterilization history information registration process may be performed without using these bottle information registered in advance. For example, when registering hand sterilization history information, the sterilization management unit 488B of the staff terminal device 4B specifies the number of times sanitary water is sprayed when the staff member presses the hand sterilization button displayed on the touch panel 45B in the logged-in state and then operates the trigger 221 of the hand spray bottle 2B. Hand sterilization history information including the user ID of the staff member who performed the sterilization, the number of times sanitary water is sprayed, the sterilization date and time, and information indicating that the hand sterilization was performed in a place other than the toilet may be generated, and a sharing process may be performed together with the process of registering it in the terminal DB 46B. In addition, a process may be performed in which the expiration date and estimated concentration of sanitary water are included in the hand sterilization history information.

[0115] 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 reading unit may be placed in the user terminal device 4, so that the item to be sterilized can be identified based on the two-dimensional code read by the two-dimensional code reading unit.

[0116] A GPS receiver for receiving a Global Positioning System (GPS) signal may be provided in the user terminal device 4, and the GPS signal may be used instead of the item tag G1 to identify the item to be sterilized. For example, position 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 is sterilizing based on the GPS signal received by the GPS receiver when sanitary water is sprayed.

[0117] For example, three beacon signal transmitters may be placed in the eating and drinking space, and beacon signals may be used instead of the item tag G1 to identify the items to be sterilized. For example, the distances from a table T, which is 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.

[0118] For example, an imaging device may be placed in the dining space, and the image captured by the imaging device installed in the dining space may be used to identify the items to be sterilized instead of the item tag G1. For example, the sterilization management unit 488B of the staff terminal device 4B may identify the items being sterilized by the staff through image recognition based on the image captured by the imaging device when sanitary water is sprayed. Furthermore, the staff performing the sterilization may be identified through image recognition.

[0119] Although the configuration in which the information on sterilization is shared between the server device 3 and the user terminal device 4 has been exemplified, the information may be collectively managed by the server device 3 (or may be 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 the item sterilization history information or the hand sterilization history information may be generated based on the information read by the reading unit 42 of the user terminal device 4 and the beacon signal received by the beacon signal receiving unit 43. In addition, the hygiene management system may not include the server device 3. In this case, the information on sterilization may be collectively managed by the manager terminal device 4A (or may be stored only in the manager terminal device 4A), or may be shared between the manager terminal device 4A and the staff terminal device 4B. In addition, the hygiene management system may not include the server device 3 and the manager terminal device 4A. In this case, the number of staff terminal devices 4B included in the hygiene management system may be one or more. When multiple staff terminal devices 4B are included in the hygiene management system, information on sterilization generated by one staff terminal device 4B may be shared among all the staff terminal devices 4B.

[0120] At least one of the server device 3, the administrator terminal device 4A, and the 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 the hand sterilization history information to an internet site that introduces restaurants.

[0121] The entrance terminal device 5 and the table terminal device 6 may display the sterilization status of each table T. For example, when the item tag G1 of the 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, when the item tag G1 of the 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.

[0122] The sterilization management unit 488 may not include at least one of the number of sprays of sanitary water, the expiration date, and the estimated concentration in at least one of the item sterilization history information and the hand sterilization history information, or may include information indicating the initial concentration instead of the estimated concentration. When information indicating the initial concentration is included instead of the estimated concentration, the warning unit 487 may issue a warning when the initial concentration of the sanitary water is less than the appropriate concentration, as in the above embodiment. The sterilization management unit 488 may not generate the item sterilization history information or the hand sterilization history information. The sterilization management unit 488 may not perform a process of determining whether the estimated concentration of the sanitary water is less than the appropriate concentration. The sterilization management unit 488 may manage the pH of the sanitary water instead of or in addition to the concentration of the active ingredient of the sanitary water. The user terminal device 4 may not be provided with a function of managing the remaining amount of sanitary water.

[0123] For example, in the registration process of item sterilization history information, if the estimated concentration of the sanitary 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 notify the user that the sanitary water is not suitable for sterilizing the specific item but can be used to sterilize the other item without issuing a warning. Although the configuration in which the appropriate concentration is different depending on the type of sterilization target (type of item, hands and fingers) has been exemplified, the appropriate concentration may be the same regardless of the type of sterilization target, and in this case, the warning unit 487 may issue a warning when the estimated concentration of the sanitary water is less than the appropriate concentration, as in the above embodiment.

[0124] Although the configuration has been exemplified in which the user terminal device 4 acquires the parameters indicating the validity of the sanitary water set by the sanitary water generating apparatus 1 via the bottle tag G2, for example, the parameters may be acquired directly from the sanitary water generating apparatus 1 through communication 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.

[0125] The user terminal device 4 may be provided with a function for displaying a monitoring screen related to the spray bottle 2. Examples of the contents displayed on the monitoring screen include the location of each spray bottle 2 in the store, the remaining amount of sanitary water, refill date and time, expiration date, and estimated concentration. The location of each spray bottle 2 in the store may be expressed 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 changed depending on whether sterilization using the spray bottle 2 is being performed, whether the remaining amount of sanitary water is equal to or greater than a threshold amount, whether the expiration date has passed, whether the estimated concentration is less than the appropriate concentration, etc.

[0126] As the disinfectant, carbonated electrolytic hypochlorous water and electrolytic hypochlorous water are exemplified, but any disinfectant having a disinfecting function, such as alcohol or sodium hypochlorite, can also be used.

[0127] Although the spray bottle 2 is exemplified as the sterilization device, the sterilization device may have a discharge unit that discharges the sterilization agent. Therefore, a sterilization device capable of contacting the sterilization agent with the sterilization target, such as a device that drips the sterilization agent or a device that applies the sterilization agent, can be used. That is, in the present disclosure, discharging the sterilization agent is a concept that includes applying the sterilization agent, dripping the sterilization agent, and contacting the sterilization agent with the sterilization target. The sterilization device may also have a function of wiping off the sterilization agent on the object. The sterilization device may also be configured only with the spray unit 22 provided with the beacon signal transmission unit 23 and the bottle tag G2, and in this case, the spray bottle 2 may be configured by attaching the spray unit 22 to a commercially available container (bottle).
