Thus, the user can use a restroom stall that has a low usage frequency and the cleanliness thereof is better preserved, and has a greater opportunity for equipment usage.

Description

[Technical field]

[0001] The present invention relates to a toilet management device and a computer program having a function of recommending toilet cubicles to a user. [Background technology]

[0002] Patent Document 1 proposes a system that uses detection signals from sensors that detect the flow of flushing water in the toilet, sensors that detect flow rate, sensors that detect the opening and closing of the toilet cubicle door, sensors that detect the remaining amount of chemical liquid in the chemical supply device, etc. to estimate the number of times the toilet is used and encourage users to use toilet cubicles that are used less frequently, thereby leveling out the frequency of toilet use. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2018-62776 A [Patent Document 2] JP 2011-152928 A [Patent Document 3] JP 2018-87466 A [Patent Document 4] Patent Publication No. 2021-20195 [Patent Document 5] JP 2018-43850 A [Patent Document 6] Patent No. 3923068 [Patent Document 7] Patent No. 5713353 [Patent Document 8] JP 2014-25320 A [Patent Document 9] WO2022 / 113744A1 publication [Patent Document 10] In Japanese Patent Publication No. 2015-151240 Summary of the Invention [Problem to be solved by the invention]

[0004] According to the technology of Patent Document 1, by presenting a toilet cubicle that is used less frequently to the user, the user can use a toilet bowl that is less soiled. Furthermore, when the frequency of use is equalized, the degree of soiling is also equalized, making cleaning work easier and facilitating the timing of maintenance such as refilling the chemical solution supply device. As a result, it becomes easier for the toilet manager to manage the toilet cubicles.

[0005] However, in Patent Document 1, a specific toilet cubicle is recommended to a user based only on the frequency of use of the toilet cubicle. On the other hand, as shown in Patent Documents 2 to 9, each toilet cubicle is equipped with various accessories for making toilet use more comfortable, such as a chemical liquid supplying device that supplies a chemical liquid into the toilet bowl, a dedicated trash can for disposing of used sanitary products, and a disinfectant dispenser for wiping and disinfecting the toilet seat before sitting down. Even if the toilet bowl of the toilet cubicle to be used is used infrequently, for example, if the disinfectant is not dispensed when the user enters the toilet cubicle to clean the toilet seat, the user is forced to choose between leaving the toilet cubicle without using it and re-entering an adjacent toilet cubicle, or giving up on the cleaning work with the disinfectant and using it. In addition, it is very inconvenient if the dedicated trash can is already full when trying to dispose of used sanitary products. Patent Document 10 describes a garbage bin with a wrapping function that counts the number of waste pieces inserted and calculates the remaining amount of wrapping film based on the detection signal of an optical sensor installed near the insertion opening, and determines whether a foreign object has been inserted based on the signal of a weight sensor that measures the weight of the inserted waste. However, although this technology detects the remaining amount and the insertion of foreign objects, and transmits the information to an administrator terminal to appropriately time the refilling of consumables and the timing of maintenance, it does not disclose how to inform the user of the information.

[0006] The present invention has been developed in consideration of the above, and has an objective of providing a toilet management device and computer program that can recommend a toilet cubicle that a user can use more comfortably, taking into account not only the frequency of use of the toilet cubicle but also the usage status of equipment.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0023] Hereinafter, the present invention will be described in more detail based on the embodiment shown in the drawings. FIG. 1 and FIG. 2 are diagrams showing a schematic configuration when managing each toilet cubicle 21 of a public toilet 2 using a toilet management device 1 according to this embodiment. The public toilet 2 is managed by the toilet management device 1 by a prior contract or the like. As shown in this figure, the toilet management device 1 of this embodiment is composed of a computer and is connected to a terminal device 3 on the public toilet 2 side via a communication means such as the Internet. The toilet management device 1 may be composed of a physical server or a cloud server in a cloud environment. The terminal device 3 may have a function capable of communicating with the toilet management device 1 and also with various sensors 21a installed in the toilet cubicle 21, and includes a personal computer (PC), a mobile terminal such as a tablet or smartphone, a repeater such as a gateway or a router, etc. In addition, the "public toilet 2" includes all toilets installed in public facilities such as government offices and community centers, commercial facilities such as department stores and supermarkets, hotels, office buildings, stations, parks, restaurants, convenience stores, etc., and used by an unspecified number of people.

[0024] The number of terminal devices 3 to be installed is not limited, and may be provided for each toilet cubicle 21, or, for example, in a department store or the like where multiple public toilets 2 are installed on the same floor, such as for men and women, a terminal device 3 may be provided for each public toilet 2 (example of N Building in FIG. 1), or may be provided for each floor when communication is possible with all of the public toilets 2 installed on the same floor, or may be provided for each building that has public toilets 2 to be managed (example of M Building in FIG. 1). The number of terminal devices 3 to be installed may be set appropriately taking into consideration the type of communication means, communication distance, performance of the terminal device 3, etc.

[0025] As shown in FIG. 3, the toilet management device 1 has a storage unit 1a (including storage media such as a hard disk built into the computer (toilet management device 1), as well as various removable storage media and storage media of other computers connected via communication means) that stores computer programs for executing procedures for functioning as a toilet cubicle usage frequency determination unit 110, a procedure for functioning as an equipment usage status determination unit 120, a procedure for functioning as a recommended toilet cubicle extraction unit 130, a procedure for functioning as a notification unit 140, and the like. The computer program of this embodiment also executes procedures for functioning as an availability determination unit 150 that determines the availability of the toilet cubicles 21. Furthermore, with regard to each toilet cubicle 21 in the public toilets 2 that are the subject of management, their location information, installation information of the equipment 22, and the like are registered in a toilet cubicle information database 1b.

[0026] The computer program can be provided by storing it in a recording medium. The recording medium storing the computer program may be a non-transient recording medium. There is no particular limitation on the non-transient recording medium, and examples of the non-transient recording medium include a flexible disk, a hard disk, a CD-ROM, an MO (magneto-optical disk), a DVD-ROM, and a memory card. It is also possible to transmit the computer program to a computer via a communication line and install it therein.

[0027] The toilet cubicle usage frequency determination unit 110 determines the usage frequency of each toilet cubicle 21 in the public toilet 2. As shown in FIG. 2, each toilet cubicle 21 is provided with a sensor 21a that detects the usage of the toilet cubicle 21. A signal from the sensor 21a is transmitted to the terminal device 3 by a communication module built into the sensor 21a or connected to the sensor 21a, and is transmitted to the toilet management device 1 via the terminal device 3. In this embodiment, the usage frequency is determined from signal data received by the toilet cubicle usage frequency determination unit 110 of the toilet management device 1. However, depending on the performance of the terminal device 3, it is also possible to configure the terminal device 3 to analyze the signal from the sensor 21a, determine the usage frequency, and transmit only the result to the toilet management device 1, and the toilet cubicle usage frequency determination unit 110 receives the data.

[0028] The type of sensor 21a that detects the use of the toilet cubicle 21 is not limited, but examples that can be used include a sensor that detects when water (flushing water) has been flushed into the toilet bowl in the toilet cubicle 21, a sensor attached to a pipe for detecting the flow rate, a sensor that detects the opening and closing of the toilet cubicle lock, a sensor that detects when the toilet seat is sat on, a sensor that is installed in each toilet bowl and measures the number of times a chemical liquid has been supplied in a chemical liquid supplying device that supplies and mixes a predetermined amount of chemical liquid with the flushing water each time the flushing water flows into the toilet bowl, a sensor that measures the remaining amount of chemical liquid in the chemical liquid supplying device, a sensor that is installed near each toilet bowl and detects the number of times a deodorizing device or fragrance device that operates when a user approaches has been operated, a sensor that detects the opening and closing of the opening and closing lid of a trash can (a container for disposing of sanitary products, etc.) installed in the toilet cubicle 21, a sensor that detects the approach of a user to the trash can, and in the case of a trash can with a packaging function that individually packages waste such as sanitary products for disposal, a sensor that detects the amount of packaging film used or remaining. The frequency of use can be measured by counting the number of detections from the detection signals of these sensors 21a, or by determining the remaining amount of the liquid medicine or packaging film.

[0029] The equipment usage status determination unit 120 determines the usage status of one or more equipment 22 provided in each toilet cubicle 21. The equipment 22 here refers to various items equipped to make the environment in the toilet cubicle 21 comfortable. For example, as disclosed in JP 2011-152928 A (Patent Document 2), there are liquid dispensers that manually or automatically discharge soap liquid, disinfectant, etc., as disclosed in JP 2018-87466 A (Patent Document 3) for spraying disinfectant into the toilet seat or toilet cubicle 21, as disclosed in JP 2021-20195 A (Patent Document 4) for spraying air fresheners, deodorants, etc. into the toilet cubicle 21, as disclosed in JP 2018-43850 A (Patent Document 5) for disposing of used sanitary products (used sanitary napkins, diapers, incontinence pads, etc.), etc. Examples of such waste containers include a waste container used to dispose of waste, a waste container that contains used sanitary products and other waste materials sandwiched between two films and sealed in a container, as disclosed in Japanese Patent Publication No. 3923068 (Patent Document 6) and Japanese Patent Publication No. 5713353 (Patent Document 7); a flush toilet medicinal liquid supplying device that supplies a predetermined amount of medicinal liquid every time flush water is flushed in a flush toilet, as disclosed in Japanese Patent Publication No. 2014-25320 (Patent Document 8); and a device that provides sanitary products such as sanitary napkins and tampons, as disclosed in WO2022 / 113744A1 (Patent Document 9). Note that the configuration of the device that provides sanitary products is not limited to this, and any structure may be used as long as it is installed in the toilet cubicle 21 and can supply sanitary products according to the user's demand. In addition, the sanitary products provided are not limited to those mainly intended for women, such as sanitary napkins, and also include devices that provide diapers, incontinence pads, and the like that can be used regardless of age or gender.

[0030] Other commercially available products include a chemical liquid supplying device called Sanitizer manufactured by Nippon Calmic Co., Ltd., sanitary boxes for disposing of used sanitary products, disposable diaper collection containers, and toilet sheet cleaners that dispense a disinfectant to sterilize toilet seats.

[0031] The equipment usage status determination unit 120 receives data obtained from the sensors 21a used in estimating the frequency of use from the usage status of the equipment 22, among the sensors 21a used in the determination by the toilet cubicle usage frequency determination unit 110, such as a sensor that detects the supply of chemical liquid in a chemical liquid supplying device, a sensor that detects the remaining amount of chemical liquid in the chemical liquid supplying device, a sensor that detects the operation of a deodorizing device or a fragrance device that is provided near each toilet and operates when a user approaches, a sensor that detects the opening and closing of the opening and closing lid of a trash can (a container for disposing of sanitary products, etc.) provided in the toilet cubicle 21, a sensor that detects the approach of a user to the trash can, and a sensor that detects the amount of packaging film used or remaining in a trash can with a packaging function that individually packages waste such as sanitary products for disposal, and determines their usage status.

[0032] For example, as disclosed in JP 2015-151240 A (Patent Document 10), in a trash can with a wrapping function, the number of waste pieces inserted can be counted based on a detection signal from an optical sensor provided near the insertion opening to calculate the remaining amount of wrapping film, and a determination can be made as to whether a foreign object has been inserted based on a signal from a weight sensor that measures the weight of the inserted waste. This allows the equipment usage status determination unit 120 to indicate the remaining amount of wrapping film as the equipment usage status, or to indicate an abnormal status such as a state in which a foreign object has been inserted.

[0033] As described above, equipment information such as the type and number of equipment 22 installed in each toilet cubicle 21 is registered in the toilet cubicle information database 1b together with individual information of the managed public toilets 2. Therefore, the equipment usage status determination unit 120 can grasp equipment information such as the type and number of equipment 22 installed for each toilet cubicle 21 by accessing the toilet cubicle information database 1b and reading the individual information.

[0034] The recommended toilet cubicle extraction unit 130 extracts a toilet cubicle 21 (recommended toilet cubicle 21X) that is recommended for use among the toilet cubicles 21 of the public toilet 2 that is the subject of management. Specifically, as shown in FIG. 4, the recommended toilet cubicle extraction unit 130 includes a first extraction unit 131 and a second extraction unit 132 having a function of extracting recommended candidates from among the toilet cubicles 21, and a determination unit 133 having a function of determining the recommended toilet cubicle 21X. The first extraction unit 131 extracts one or more recommended toilet cubicles 21 based on information on the frequency of use determined by the toilet cubicle use frequency determination unit 110. The second extraction unit 132 extracts one or more toilet cubicles 21 whose available amount is determined to be equal to or greater than a predetermined threshold value based on information on the available amount of at least one piece of equipment 22 among the one or more pieces of equipment 22 determined by the equipment use status determination unit 120 as recommended candidates. The determination unit 133 determines the recommended toilet cubicle 21X to be finally notified to the user from among the one or more recommended candidates extracted by the first extraction unit 131 and the one or more recommended candidates extracted by the second extraction unit 132.

[0035] The first extraction unit 131 is preferably configured to extract recommended candidates in the order of least frequent use as determined by the toilet cubicle use frequency determination unit 110. When the frequency of use is low, the degree of dirt is often low, and the frequency of use of the toilet cubicle 21 can be equalized, so it is preferable to extract recommended candidates in the order of least frequent use.

[0036] The second extraction unit 132 may be configured to extract at least one piece of equipment 22 whose usable amount is determined to be equal to or greater than a predetermined threshold, but in that case, the number of recommended toilet cubicles 21 may be increased. In view of this, it is preferable that the second extraction unit is configured to extract toilet cubicles 21 whose usable amount of the priority equipment 22A, which places importance on the determination of the usable amount, is determined to be equal to or greater than a predetermined threshold. For example, as shown in FIG. 5, when a plurality of pieces of equipment 22 are installed in a toilet cubicle 21, the priority equipment 22A may be specified in advance so that a disinfectant sprayer and a trash can are the priority equipment 22A, or may be appropriately set at the request of the manager of the public toilet 2. Of course, the priority order may be appropriately changed depending on the installation location of the public toilet 2. The priority equipment 22A is registered in the toilet cubicle information database 1b in association with the individual information of each toilet cubicle 21. Therefore, the second extraction unit 132 identifies the priority equipment 22A for each toilet cubicle 21, and extracts recommended candidates by acquiring information on the priority equipment 22A as the available amount determined by the equipment usage status determination unit 120. As a result, the recommended candidates extracted by the second extraction unit 132 are narrowed down more than when the priority equipment 22A is not identified.

[0037] The second extraction unit 132 may also be configured to extract, as a recommendation candidate, a toilet cubicle 21 in which the usable amount of all of the equipment 22 is determined to be equal to or greater than a predetermined threshold by the equipment usage status determination unit 120, among one or more pieces of equipment 22 installed in the toilet cubicle 21. In this case, when the usable amount of at least one piece of equipment 22 in the toilet cubicle 21 is equal to or greater than a predetermined threshold, the recommendation candidates can be narrowed down compared to the case where all of the equipment 22 are extracted. Note that the second extraction unit 132 can extract, not only at least one target equipment 22 determined to be equal to or greater than a predetermined threshold, but also equipment 22 not determined to be equal to or greater than a predetermined threshold, specific conditions regarding the usable amount for each piece of equipment 22, such as "high", "low", "usable number of times: ○ times", "remaining amount: ○ sheets", etc., as reference information.

[0038] Here, the "predetermined threshold value" used in the equipment usage status determination unit 120 can be set arbitrarily, for example, to 1 / 3 of the total amount for a disinfectant sprayer, or to 1 / 5 of the total amount of packaging film for a trash can equipped with packaging film for sealing waste. The value may be a predetermined value for each equipment 22, or may be set to a predetermined value at the request of the manager of the public toilet 2. The cycle of maintenance work such as refilling liquid and replacing film for each equipment 22 varies depending on the type of equipment 22. In addition, the maintenance cycle may be such that the manager of the public toilet 2 performs refilling, replacement, etc. every day or every few days, or the provider of the equipment 22 visits the facility to perform the work once a month to once every few months. Therefore, as shown in Figure 6, it is preferable that the "predetermined threshold value" for each piece of equipment 22 is set by reading information on the maximum usable amount and maintenance cycle of each piece of equipment 22 from the toilet cubicle information database 1b, obtaining information on the frequency of use of the toilet cubicle 21 from the toilet cubicle use frequency determination unit 110, and using these to determine the usable period of each piece of equipment 22, and setting a value such that the amount of liquid, film, etc. to be replenished or replaced does not remain between the time the previous maintenance work is performed and the time the next maintenance work is performed.

[0039] The determination unit 133 determines the recommended toilet cubicle 21X from among the recommended candidates extracted from the two extraction units 131, 132 as described above, and the method of determination is not limited as long as it has this function.

[0040] For example, the configuration may be such that, among one or more recommended candidate toilet cubicles 21 extracted by the first extraction unit 131 and one or more recommended candidate toilet cubicles 21 extracted by the second extraction unit 132, the toilet cubicle 21 that is extracted as being overlapping is determined as the recommended toilet cubicle 21X. When the first extraction unit 131 extracts, for example, two toilet cubicles 21A and 21C shown in Fig. 2 as being used less frequently, and the second extraction unit 132 extracts toilet cubicles 21C and 21D as having priority equipment 22A that is equal to or greater than a predetermined threshold or all equipment 22 that is equal to or greater than a predetermined threshold, the overlapping toilet cubicle 21C is determined as the recommended toilet cubicle 21X.

[0041] In addition, the determination unit 133 can be configured to weight the recommended toilet cubicles 21 extracted by the first extraction unit 131 in order of least frequent use, and weight the recommended toilet cubicles 21 extracted by the second extraction unit 132 in order of most usable accessories 22, and determine the recommended toilet cubicle 21X in order of highest overall weight, which is the sum of the two weights.

[0042] For example, suppose that six toilet cubicles 21A to 21F are installed in the public toilet 2 to be managed, as shown in Fig. 2. In this case, when four toilet cubicles 21A, 21B, 21C, and 21F are extracted by the first extraction unit 131 as shown in Fig. 7, the toilet cubicles are weighted in order of least frequent use, for example, 10, 8, 6, and 4 in that order, assuming that the toilet cubicles 21A, 21B, 21C, and 21F are used least frequently. Similarly, when three toilet cubicles 21A, 21C, 21F are extracted by the second extraction unit 132, in order of the number of available accessories 22, for example, in the toilet cubicle 21A, the disinfectant sprayer, the trash can, and the chemical liquid supply device are determined to be equal to or above the predetermined threshold, in the toilet cubicle 21C, the disinfectant sprayer, the trash can, the chemical liquid supply device, and the deodorizer are determined to be equal to or above the predetermined threshold, and in the toilet cubicle 21F, the disinfectant sprayer and the chemical liquid supply device are determined to be equal to or above the predetermined threshold, the weight of the toilet cubicle 21A is assigned as 8, the weight of the toilet cubicle 21C as 10, and the weight of the toilet cubicle 21F as 6. Then, a total weight taking into account the weights of both is calculated.

[0043] For example, if the weight of a toilet cubicle not extracted in either is set to 0, the total weight obtained by adding up the weights of both is as follows: toilet cubicle 21A: 10+8=18, toilet cubicle 21B: 8+0=8, toilet cubicle 21C: 6+10=16, toilet cubicle 21D: 0+0=0, toilet cubicle 21E: 0+0=0, toilet cubicle 21F: 4+6=10. Toilet cubicles 21D and 21E were not extracted in either the first or second extraction unit 131, 132. This includes cases where they were not extracted because they were frequently used and had a small amount of available equipment 22, as well as cases where they were not extracted because they were determined to be "in use" by the availability determination unit 150 described below.

[0044] Therefore, in this case, the toilet cubicle 21A with the highest overall weight becomes the recommended toilet cubicle 21X. Of course, the method of weighting and the method of calculating the overall weight are not limited to the above, but it is preferable to set the toilet cubicle 21 that is used less frequently and has more available accessories 22 to become the recommended toilet cubicle 21X. The determination unit 133 may determine not only one but also multiple recommended toilet cubicles 21X. For example, the three toilet cubicles 21A, 21C, and 21F may be determined as the recommended toilet cubicles 21X in descending order of the overall weight. In this case, an overall weight ("weight" is not limited to a numerical value, and includes a display method such as "A" for an overall weight of 15 or more and "B" for an overall weight of 10 to 15) may be assigned, and multiple recommended toilet cubicles 21X may be assigned the overall weight values.

[0045] In addition, the recommended toilet cubicle extraction unit 130 can recommend not only the overall weight of the recommended toilet cubicle 21X, but also the contents of the equipment 22 that can be used in the recommended toilet cubicle 21X (type of equipment 22, usable amount (remaining amount of disinfectant or packaging film, etc.)).

[0046] The notification unit 140 notifies one or more of the recommended toilet cubicles 21X extracted by the recommended toilet cubicle extraction unit 130. Specifically, it has a function of receiving information about the recommended toilet cubicle 21X from the recommended toilet cubicle extraction unit 130, and displaying it on various displays or the like that are notification destinations, or notifying by voice. Examples of notification destinations include a dedicated display 4 (see FIG. 2) installed near the entrance to the public toilet 2 in a parking lot on a highway, a department store, an office building, or the like, or at the entrance of the building in which the public toilet 2 is installed or in a place with a lot of foot traffic on each floor, a display of a mobile terminal such as a smartphone of a user who uses the public toilet 2, and when notifying by voice, a speaker installed near the public toilet 2 or a speaker of the user's smartphone, etc.

[0047] In the case where the notification destination is the display 4 installed at the entrance of the public toilet 2 as shown in Fig. 2, for example, as shown in Fig. 8(a), a map showing the positions of each toilet cubicle 21 in the public toilet 2 can be displayed, and a function of issuing a command to clearly indicate the position on the map, for example, by displaying only the recommended toilet cubicle 21X (for example, the toilet cubicle 21A) in a different color, can be configured. In addition, when there are multiple recommended toilet cubicles 21X by the recommended toilet cubicle extraction unit 130, the multiple toilet cubicles (for example, the toilet cubicles 21A, 21C, 21F) can be clearly indicated by displaying them in different colors (see Fig. 8(b)). In that case, it is also possible to indicate the first and second candidates based on the recommendation order by different colors or order display, etc. Furthermore, for example, for three toilet cubicles 21A, 21C, and 21F extracted as recommended toilet cubicles 21X, as shown in Figure 8(b), the evaluation results can also be displayed, such as toilet cubicle 21A having a frequency of use weight of 10 and a weight for equipment 22 of 8, toilet cubicle 21C having a frequency of use weight of 6 and a weight for equipment 22 of 10, and toilet cubicle 21F having a frequency of use weight of 4 and a weight for equipment 22 of 8. In addition, by displaying and informing the user of the frequency of use of the non-recommended toilet cubicles 21B, 21D, 21B and information regarding the equipment 22, for example, even if the user checks the recommended toilet cubicle 21X by looking at the display 4 installed at the entrance of the public toilet 2 and there is a change in the situation in the short time between the user's arrival at the recommended toilet cubicle 21X from the entrance of the public toilet 2 and the recommended toilet cubicle 21X (for example, a third party suddenly enters the recommended toilet cubicle 21X during that time), the user can select the toilet cubicle 21 based on the item that the user places more importance on (for example, frequency of use). In addition, as described above, when the recommended toilet cubicle extraction unit 130 recommends the contents of the equipment 22 that can be used in the recommended toilet cubicle 21X (type of equipment 22, usable amount (remaining amount of disinfectant or packaging film, etc.)), the information can also be specifically shown (number of times that can be used, etc.).

[0048] By displaying detailed evaluation results in this way, when a user of the public toilet 2 compares toilet cubicle 21A with toilet cubicle 21C, for example, even if toilet cubicle 21A has a higher overall weight, the user may select toilet cubicle 21C which is more fully equipped with the fixtures 22, thereby meeting the user's needs. Also, by displaying recommended toilet cubicle 21X on a map showing the positions of each toilet cubicle 21 in the public toilet 2, some users may select one located closer to the public toilet 2, and among those, one which is fully equipped with the specified fixtures 22 that meet the user's needs.

[0049] As described above, when the determination unit 133 determines a plurality of recommended toilet cubicles 21X, and when the recommended toilet cubicle extraction unit 130 is configured to recommend not only the evaluation result (weight) of the recommended toilet cubicle 21X but also the contents of the equipment 22 that can be used in the recommended toilet cubicle 21X (type of equipment 22, usable amount (remaining amount of disinfectant or packaging film, etc.)), in the example of FIG. 8(b), even if the user who actually uses the toilet cubicle has a high overall weight for the toilet cubicle 21A, for example, the toilet cubicle with a higher degree of equipment 22 may be selected. There are also cases where the user selects cubicle 21C. Also, when toilet cubicle 21C is filled up, toilet cubicle 21A and toilet cubicle 21F are compared, and instead of toilet cubicle 21A, which has a relatively large remaining amount of accessories 22 that is the subject of judgment of the predetermined threshold value in second extraction unit 132, if the above-mentioned reference information attached in second extraction unit 132 indicates, for example, that toilet cubicle 21F has a larger remaining amount of the sanitary product providing device than toilet cubicle 21A, the user may select said toilet cubicle 21F.

[0050] Therefore, it is preferable to use such a user's final selection result as a criterion for determining a recommended toilet cubicle in the recommended toilet cubicle extraction unit 130. As shown in Fig. 9, for example, when the above-mentioned priority equipment 22A is set in the second extraction unit 132, the target equipment is not set in advance, but a final selection result information analysis unit 135 is provided that statistically processes or machine-learns the user's final selection result, and the final selection result information is fed back from the final selection result information to the second extraction unit 132, which specifies the priority equipment 22A based on the final selection result information, and extracts toilet cubicles 21 in which the usable amount of the priority equipment 22A is determined to be equal to or greater than a predetermined threshold. When the final selection result information analysis unit 135 determines that, for example, toilet cubicles 21 in which the usable amount of a waste storage device or a sanitary product provision device of a sanitary product is high in the user's final selection result, the waste storage device or the sanitary product provision device is set as the priority equipment 22A in the second extraction unit 132. The setting of the priority equipment 22A is automatically fed back by statistical processing and machine learning based on the user's final selection result information, so it is possible to match the type of priority equipment 22A to the actual usage conditions of the user, which change depending on the toilet installation location, season, climate, etc.

[0051] The recommended toilet cubicle 21X is selected from among the toilet cubicles 21 in the public toilet 2 that are available at the time the user intends to use the toilet cubicle. For this reason, in this embodiment, an availability determination unit 150 is provided that determines the availability of each toilet cubicle 21 (see FIG. 3). The availability determination unit 150 receives detection signals from various sensors 21a used in the toilet cubicle usage frequency determination unit 110, determines the entry / exit status of the toilet cubicle 21, and thereby determines the availability. For example, the availability determination unit 150 receives detection signals from a sensor that detects whether the door 21b of each toilet cubicle 21 is open or closed, a sensor that detects whether the door 21b is locked, and the like, via the terminal device 3, and determines whether the toilet cubicle 21 is available or in use based on the detection signals.

[0052] The determination result of the availability by the availability determination unit 150 is updated whenever there is a change in the availability so that it is always up to date, and each process by the toilet cubicle usage frequency determination unit 110, the equipment usage status determination unit 120, and the recommended toilet cubicle extraction unit 130 is preferably performed for toilet cubicles 21 that have been determined to be "available" by the availability determination unit 150. Since the availability determination unit 150 is always detecting the latest status, the recommendation result of the recommended toilet cubicle 21X is also updated each time, and users of the public toilet 2 can always know recommended candidates from among the available toilet cubicles 21.

[0053] In addition, as shown in Fig. 9, when the availability determination unit 150 detects that the user has entered a specific toilet cubicle 21 and obtains the information, the final selection result information analysis unit 135 compares the recommended result of the recommended toilet cubicle 21X displayed immediately before the user's entry timing with the recommendation result of the recommended toilet cubicle 21X displayed immediately before the user's entry timing, and determines which is the basis information for the user's final selection of the toilet cubicle 21. For example, if the user follows the evaluation result (weight) of the recommended toilet cubicle 21X as it is, the evaluation result is the basis information, and if the user selects a toilet cubicle based on the above-mentioned reference information attached in the second extraction unit 132, the reference information is the basis information, and outputs the information as the final selection result information. For example, if the content shown in Fig. 8(b) is displayed on the display 4 immediately before the user's entry timing, it analyzes whether the user selected the toilet cubicle 21A with the highest total weight, the toilet cubicle 21C with the highest weight of the equipment 22, or the toilet cubicle 21F with the largest remaining amount of a specific equipment 22. Then, the final selection result information is fed back to the second extraction unit 132 as described above.

[0054] In addition, since the toilet cubicle usage frequency determination unit 110 detects the usage of the toilet cubicle 21 and determines the frequency of usage, it can also determine whether the current state of the toilet cubicle 21 is vacant or in use. Toilet cubicle usage frequency determination unit The function of the vacancy status determination unit 150 may be provided in the vacancy status determination unit 110, and such a configuration is also included in the present embodiment.

[0055] According to this embodiment, a user who intends to use the public toilet 2 can grasp the recommended toilet cubicle 21X, which is determined by taking into consideration both the toilet cubicle 21 that is a recommended candidate in terms of frequency of use and the toilet cubicle 21 that is a recommended candidate in terms of the available amount of the accessories 22, on the display 4 or the like that is the notification destination of the notification unit 140. Thus, the user can use the toilet cubicle 21 that is assumed to be comfortable in terms of frequency of use and is equipped with a full range of accessories 22, and it is possible to achieve both the equalization of the use of the toilet cubicle 21 and the comfort of toilet use. As a result, the degree of dirtiness of each toilet cubicle 21 is equalized, making maintenance easier, and this also leads to the equalization of the maintenance of the accessories 22, which contributes to reducing the total maintenance cost.

[0056] FIG. 10 is a conceptual diagram showing another embodiment of the present invention. In this embodiment, a computer program executes a procedure that functions as a dirt state determination unit 160 in addition to the components of the above embodiment. The dirt state determination unit 160 receives detection signals from sensors that determine the dirt state installed in each toilet cubicle 21, such as a wetness detection sensor installed on the floor surface around the toilet bowl and an odor sensor installed at an appropriate position in the toilet cubicle 21, via the terminal device 3, and has a function of excluding the toilet cubicle 21 from the recommended candidates as having a high degree of dirt state when the amount of liquid dripping on the floor surface exceeds a predetermined threshold value or the odor exceeds a predetermined threshold value. In other words, it has a function of extracting toilet cubicles 21 in which the amount of liquid dripping or the odor is below a predetermined threshold value.

[0057] As shown in FIG. 11, the recommended toilet cubicle extraction unit 130 has a third extraction unit 134 that extracts toilet cubicles 21 whose degree of dirtiness is determined to be below a predetermined threshold by the dirtiness state determination unit 160 as recommended candidates, and the determination unit 133 determines the recommended toilet cubicle 21X by taking into account the recommended candidates extracted by this third extraction unit 134 in addition to the recommended candidates by the first extraction unit 131 and the second extraction unit 132 described above.

[0058] In the determination unit 133, a method of taking into account the recommended candidates extracted by the third extraction unit 134 can be, for example, a method in which the toilet cubicle 21 that is extracted as a duplicate of all of the recommended candidate toilet cubicles 21 extracted by the first extraction unit 131, the recommended candidate toilet cubicles 21 extracted by the second extraction unit 132, and the recommended candidate toilet cubicles 21 extracted by the third extraction unit 134 is determined to be the recommended toilet cubicle 21X.

[0059] Also, similarly to the above embodiment, the recommended toilet cubicle 21X can be determined in descending order of overall weight by weighting the recommended candidates extracted by the respective extraction units 131, 132, 134 (see FIG. 7). For example, the recommended toilet cubicle 21 extracted by the first extraction unit 131 is weighted in descending order of frequency of use, the recommended toilet cubicle 21 extracted by the second extraction unit 132 is weighted in descending order of number of available accessories 22, and the recommended toilet cubicle 21 extracted by the third extraction unit 134 is weighted in descending order of dirtiness, and the recommended toilet cubicle 21X is determined in descending order of overall weight, which is a combination of these three weights.

[0060] Also, the decision unit 133 can select a plurality of recommended toilet cubicles 21X after taking into consideration the recommended candidates extracted by the third extraction unit 134, and further, the notification unit 140 can display the plurality of recommended toilet cubicles 21X together with their weights (evaluations) and detailed contents of the accessories 22 (information such as type and remaining amount) on the display 4, which is the notification destination (see FIG. 8). It is also possible to display the dirt state of the recommended toilet cubicle 21X determined by the dirt state determination unit 160. The dirt state can be notified by displaying, for example, an index indicating the degree of wetness of the floor obtained from the detection signal by the wetness detection sensor or an index indicating the degree of odor from the detection signal of the odor sensor. Note that the index here includes various display modes such as numerical values, symbols, figures, and messages.

[0061] According to this embodiment, for example, even if the toilet cubicle 21A has a high overall weight in the results extracted by the first extraction unit 131 and the second extraction unit 132 in the above embodiment, when the weight (evaluation) by the third extraction unit 134 is combined, the overall weight may be lower than that of other toilet cubicles 21. In addition, by displaying the weights and indicators related to the soiling state obtained by each extraction unit 132, 132, 134 on the display 4, for example, a user may appear who selects a toilet cubicle 21 with a high weight (evaluation) by the third extraction unit 134 even if the overall weight is relatively low.

[0062] In addition, in this embodiment, even if the toilet cubicle 21 is determined by the first extraction unit 131 to be used infrequently, the third extraction unit 134 may determine that the odor exceeds a predetermined threshold, and the cleanliness of each toilet cubicle 21 can be determined by considering factors other than the frequency of use. As a result, the user can use the toilet cubicle 21 more comfortably. Depending on the state of dirt, immediate cleaning work may be required, and a function for communicating such a state to the manager of the public toilet 2 can be provided. In addition, by accumulating the tendency of the user to select the toilet cubicle 21 in the final selection result information analysis unit 135, it is possible to grasp the type of equipment 22 that the user places importance on when using the toilet, among the multiple types of equipment 22. By using this information, the manager of the public toilet 2 can consider what is desired to be installed and what does not need to be installed, and it is also easy for the supplier of the equipment 22 to recommend the type of equipment 22 that meets the needs of the manager and the user.
