DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0011] Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. In the drawings for explaining the embodiment, the same components are generally designated by the same reference numerals, and the repeated description will be omitted.

[0012] <First embodiment> <Summary> The hand-washing device 1 described in this embodiment can be installed in various locations, such as indoors and outdoors. The hand-washing device 1 is installed indoors, for example, near the entrance of a building, in the office space of a business operator who occupies the building, near the entrance of a store, etc. For example, if the building is a facility for accommodation, exercise, entertainment, etc. and check-in is required to use the facility, the hand-washing device 1 is installed in a location where check-in takes place. For example, it is assumed that a user will wash his or her hands with the hand-washing device 1 before or after filling out certain items with a shared writing instrument in order to check in.

[0013] <Overall composition> The overall configuration of the hand washing device 1 according to this embodiment will be described. Fig. 1 is an external perspective view of the hand washing device 1 of the present invention. Fig. 2 is a top view of the hand washing device 1. As shown in FIG. 1A, the hand-washing device 1 includes a housing 2 and an external module 7. The housing 2 is provided with a hand washing basin 11, a water faucet 12, and a dispenser 14.

[0014] <Configuration of Chassis 2> The housing 2 has a cylindrical shape. The housing 2 is formed by processing, for example, a drum can. A top plate 10 is provided on the upper part of the housing 2. An installation hole penetrating the top plate 10 is formed in the center of the top plate 10.

[0015] 1B, an access hole 4 is formed on the outer circumferential surface of the housing 2, which provides access to a circulation unit 6 provided inside the housing 2. Note that the entire configuration of the circulation unit 6 is not necessarily provided inside the housing 2, and at least a part of the circulation unit 6 may be disposed outside the housing 2 as a part of an external module 7.

[0016] A door 3 that can be opened and closed freely to cover the access hole 4 is provided on the periphery of the access hole 4 of the housing 2. With the door 3 open, maintenance of the inside of the housing 2 can be performed through the access hole 4.

[0017] 2, hand-washing basin 11 is provided in a part of housing 2, and has a circular bowl shape when viewed from above. In the illustrated example, hand-washing basin 11 is arranged so as to be fitted into an installation hole in top plate 10 provided in housing 2.

[0018] A drain port 17 is formed at the bottom of the hand-washing basin 11 to drain the wash water discharged into the basin. As shown in FIG. 1A, an overflow hole 18 is formed on the inner surface of the hand-washing basin 11 to drain the washing water when the washing water in the basin exceeds a predetermined water level, thereby preventing the washing water from overflowing onto the top plate 10.

[0019] As shown in Fig. 2, a water outlet 13 for discharging wash water is formed at the tip of the faucet 12. The faucet 12 is provided with an infrared sensor 23 (see Fig. 5). The infrared sensor 23 is provided next to the water outlet 13 at the tip of the faucet 12. When the infrared sensor 23 detects an object, flush water is discharged from the water outlet 13 of the faucet 12. The position of the infrared sensor 23 provided on the faucet 12 is not limited to the tip, but can be changed arbitrarily.

[0020] As shown in Fig. 1B, the base of the faucet 12 is attached to the top plate 10. The faucet 12 extends upward from the base to the tip, and is curved in the middle so that the spout 13 located at the tip faces downward.

[0021] In the following description, the direction from faucet 12 to hand-washing basin 11 in top view shown in FIG. 2 is referred to as the front of hand-washing device 1, and the opposite direction is referred to as the rear of hand-washing device 1. In addition, the left and right directions of a user using the hand-washing device 1 from the front of the hand-washing device 1 are referred to as the sides of the hand-washing device 1.

[0022] The faucet 12 is rotatable around the base. When the faucet 12 rotates around the base, the position of the water outlet 13 changes. That is, water outlet 13 can be positioned above hand-washing basin 11 as shown in Fig. 2, or above the outside of housing 2 as shown in Fig. 4. Fig. 4 is an external view of hand-washing device 1 with the position of water outlet 13 changed.

[0023] Here, the state in which the water outlet 13 of the faucet 12 is located above the hand-washing basin 11, i.e., the state in which the faucet 12 extends forward from the base to the tip when viewed from above as shown in Figure 2, is referred to as the first state. In addition, the state in which the water outlet 13 of the faucet 12 is located above and outside the housing 2, that is, the state in which the water faucet 12 extends rearward from the base to the tip when viewed from above as shown in Figure 4, is referred to as the second state.

[0024] 1A and 1B, dispenser 14 ejects a skin hygiene agent from a nozzle toward the inside of hand-washing basin 11. The skin hygiene agent includes a cleanser for washing the skin (e.g., a detergent such as soapy water) and a bactericidal liquid or hand lotion (e.g., a disinfectant containing an ingredient such as alcohol). Dispenser 14 is provided with infrared sensor 52 (see FIG. 5). Infrared sensor 52 is provided, for example, near the base of the nozzle of dispenser 14 so as to be able to detect a hand approaching hand-washing tub 11. When an object is detected by the infrared sensor 52, the medicine is discharged from the nozzle tip of the dispenser 14.

[0025] A hand-washing indicator 15 (first indicator), which is an indicator light that displays an estimate of the user's hand-washing time, is provided on the top surface of the housing 2. The hand-washing indicator 15 is disposed on the top surface of the top plate 10 of the housing 2. The hand-washing indicator 15 is disposed on the outer side of the hand-washing basin 11 on the upper surface of the top plate 10, and is formed on the upper edge of the hand-washing basin 11 so as to surround the hand-washing basin 11.

[0026] The hand-washing indicator 15 is composed of, for example, a plurality of LED lights. The plurality of LED lights are arranged, for example, on the upper edge of the hand-washing basin 11 at intervals in the circumferential direction. In this embodiment, the hand-washing indicator 15 is made up of 30 LED lights. The display mode of the hand-washing indicator 15 and the control process thereof will be described later.

[0027] (Configuration of Circulation Unit 6) FIG. 5 is a block diagram showing the circulation unit 6 of the hand-washing device 1. Inside the housing 2, a circulation unit 6 that purifies and circulates the cleaning water, and a control unit 60 that controls the circulation unit 6 are provided.

[0028] The control unit 60 includes a communication IF, an input / output IF, a memory, a storage, and a processor. The communication IF is an interface for inputting and outputting signals so that the control unit can communicate with an external device.

[0029] The input / output IF functions as an interface with an input device for receiving input operations from a user and an output device for presenting information to the user. The memory is for temporarily storing programs and data to be processed by the programs, and is a volatile memory such as a dynamic random access memory (DRAM).

[0030] The storage is a storage device for saving data, such as a flash memory or a hard disk drive (HDD). A processor is hardware for executing a set of instructions written in a program, and is composed of an arithmetic unit, registers, peripheral circuits, and the like.

[0031] As shown in FIG. 5, the circulation unit 6 includes at least a water discharge unit 20, a drainage unit 30, and a purification unit .

[0032] The water discharge unit 20 has a function of discharging the water purified by the purification unit 40 from the water outlet 13 of the faucet 12 in the circulation unit 6 .

[0033] The water discharge unit 20 mainly includes a water discharge pump 21, a UV sterilization section 22, and an infrared sensor 23.

[0034] The discharge pump 21 is disposed downstream of the water storage tank 46 provided in the purification unit 40. The discharge pump 21 is operated under the control of the control unit 60, and sends out water stored in the water storage tank 46 to the UV sterilization unit 22. Specifically, the control unit 60 operates the discharge pump 21 in response to detection of an object by the infrared sensor 23. For example, the control unit 60 operates the discharge pump 21 while an object is detected by the infrared sensor 23. The control unit 60 stops the discharge pump 21 when an object is no longer detected by the infrared sensor 23.

[0035] The UV sterilization unit 22 is disposed between the discharge pump 21 and the faucet 12. The UV sterilization unit 22 irradiates the water discharged from the discharge pump 21 with ultraviolet light to sterilize the water. The water that has passed through the UV sterilization unit 22 is discharged from the water outlet 13 of the faucet 12 as wash water. An air vent 72 for removing air from the water discharged from the water discharge pump 21 is provided between the water discharge pump 21 and the UV sterilization unit 22.

[0036] Drainage unit 30 has the function of draining wash water discharged from faucet 12 toward hand-washing basin 11 in circulation unit 6.

[0037] The drainage unit 30 mainly includes a trap 35 , a capacitance sensor 31 , and a drainage pump 32 . Trap 35 is provided in the pipe that drains the wash water from hand-washing basin 11. Trap 35 prevents, for example, bad odors or gases from flowing back, and prevents foreign matter that has entered through drain outlet 17 from reaching purification unit 40.

[0038] The drainage pump 32 is disposed after the trap 35. The drainage pump 32 is operated under the control of the control unit 60, and sends the water that has passed through the trap 35 to a pre-treatment filter 41 provided in the purification unit 40. Specifically, the control unit 60 operates the drainage pump 32 in response to the detection of water by the capacitance sensor 31. For example, the control unit 60 operates the drainage pump 32 while water is detected by the capacitance sensor 31. The control unit 60 stops the drainage pump 32 when water is no longer detected by the capacitance sensor 31.

[0039] Capacitance sensor 31 is disposed between trap 35 and drain pump 32. Capacitance sensor 31 detects the capacitance in the drain pipe. This allows detection of water drained from hand-washing basin 11 and supplied via trap 35. Note that the sensor for detecting the water supply is not limited to capacitance sensor 31. The water supply may be detected by referring to other sensing results.

[0040] An air vent 70 is provided between the drainage pump 32 and the purification unit 40 to remove air from the water discharged from the drainage pump 32.

[0041] The purification unit 40 has a function of purifying the water supplied from the drainage unit 30 in the circulation unit 6.

[0042] The purification unit 40 mainly comprises a pre-treatment filter 41, a reverse osmosis membrane 42, a post-treatment filter 43, an intermediate tank 44 (first tank), a wastewater tank 45 (second tank), a water storage tank 46 (third tank), and a membrane filtration pump 47.

[0043] The pre-treatment filter 41 is disposed after the drainage pump 32. The pre-treatment filter 41 performs pre-treatment on the water discharged from the drainage pump 32 to remove solid matter, water pollutant components, low molecular weight surfactants, carbonic acid components (detergent components), and the like. In this embodiment, an activated carbon filter is used as the pretreatment filter 41, but is not limited thereto. For example, at least one of a thread-wound filter, a sediment filter, a MF (microfiltration membrane), a UF (ultrafiltration membrane), a NF (nanofiltration membrane), a ceramic filter, an ion exchange filter, and a metal membrane may be selected. In this embodiment, the pretreatment filter 41 is disposed outside the housing 2 as a part of the external module 7. A pressure sensor 33 is disposed upstream of the pre-treatment filter 41. The pressure sensor 33 detects the pressure of the water supplied to the pre-treatment filter 41.

[0044] A flow rate sensor 34 is disposed downstream of the pre-treatment filter 41. The flow rate sensor 34 detects the flow rate of the water that has been pre-treated by the pre-treatment filter 41.

[0045] The intermediate tank 44 (first tank) is disposed after the pre-treatment filter 41. The intermediate tank 44 is a tank for storing the supplied water. Water that has been pretreated by the pretreatment filter 41 and concentrated water that has been separated by the reverse osmosis membrane 42 and passed through the two-way electromagnetic valve 74 flow into the intermediate tank 44. The intermediate tank 44 stores the water that flows in from the two systems. A water level sensor is disposed in the intermediate tank 44. The water level sensor detects the level of the water stored in the intermediate tank 44.

[0046] The membrane filtration pump 47 is disposed between the intermediate tank 44 and the reverse osmosis membrane 42 . The membrane filtration pump 47 is operated under the control of the control unit 60, and increases the pressure of the water stored in the intermediate tank 44 to a preset pressure, and supplies the water to the reverse osmosis membrane 42. Note that the preset pressure is, for example, a pressure that is at least higher than the osmotic pressure.

[0047] The reverse osmosis membrane 42 separates the water, which is pressurized and supplied by the membrane filtration pump 47, into permeated water from which dissolved components have been removed and concentrated water from which the dissolved components have been concentrated. The reverse osmosis membrane 42 is realized by, for example, a spiral reverse osmosis membrane. The concentrated water separated by the reverse osmosis membrane 42 is discharged to the intermediate tank 44 via the two-way solenoid valve 74 and the pressure regulating valve 73 when the two-way solenoid valve 74 is open. The concentrated water separated by the reverse osmosis membrane 42 is discharged to the wastewater tank 45 via the two-way solenoid valve 75 when the two-way solenoid valve 75 is open. The permeated water separated by the reverse osmosis membrane 42 is discharged to the post-treatment filter 43.

[0048] The two-way solenoid valve 74 is a device that opens and closes the valve by the electromagnetic force of an electromagnetic coil. The two-way solenoid valve 74 is structured so that the valve is open in a normal state and closes in response to a signal from the control unit 60.

[0049] The pressure regulating valve 73 adjusts the flow rate or pressure of the concentrated water supplied to the intermediate tank 44 .

[0050] The two-way solenoid valve 75 is a device that opens and closes the valve by the electromagnetic force of an electromagnetic coil. The two-way solenoid valve 75 is structured so that the valve is closed in a normal state and opens in response to a signal from the control unit 60.

[0051] A sensor unit 61 is disposed upstream of the reverse osmosis membrane 42. In the illustrated example, the sensor unit 61 has a pressure sensor, a flow rate sensor, and an EC / temperature sensor.

[0052] The pressure sensor detects the pressure of the water supplied to the reverse osmosis membrane 42 .

[0053] The flow rate sensor detects the flow rate of water supplied to the reverse osmosis membrane 42 .

[0054] The EC / temperature sensor detects the electrical conductivity and temperature of the water supplied to the reverse osmosis membrane 42 . In addition to the above-mentioned sensors, the sensor unit 61 may have a sensor that senses at least one of the following: (1) pH, oxidation-reduction potential, alkalinity, ion concentration, hardness (2) Turbidity, color, viscosity, dissolved oxygen (3) Odor, ammonia nitrogen, nitrate nitrogen, nitrite nitrogen, total nitrogen, residual chlorine, total phosphorus, total organic carbon, total inorganic carbon, total trihalomethanes (4) Detection results of microbial sensors, chemical oxygen demand, biological oxygen demand, (5) Cyanide, mercury, oil, surfactants (6) Detection results of optical sensors and TDS (Total Dissolved Solids) sensors (7) Mass spectrometry results, fine particles, zeta potential, surface potential

[0055] An air vent 71 for removing air from the water discharged from the membrane filtration pump 47 is provided between the membrane filtration pump 47 and the sensor unit 61 .

[0056] The post-treatment filter 43 is disposed after the reverse osmosis membrane 42. The post-treatment filter 43 performs post-treatment on the permeated water discharged from the reverse osmosis membrane 42 to remove impurities that could not be completely filtered by the reverse osmosis membrane. In this embodiment, an activated carbon filter is used as the post-treatment filter 43, but is not limited thereto. For example, at least one of a thread-wound filter, a sediment filter, a MF (microfiltration membrane), a UF (ultrafiltration membrane), a NF (nanofiltration membrane), a ceramic filter, an ion exchange filter, and a metal membrane may be selected. In this embodiment, the post-treatment filter 43 is disposed outside the housing 2 as a part of the external module 7.

[0057] A sensor unit 62 is disposed in front of the post-processing filter 43. In the illustrated example, the sensor unit 62 has a pressure sensor, a flow rate sensor, and an EC / temperature sensor.

[0058] The pressure sensor detects the pressure of the permeated water supplied to the post-treatment filter 43 .

[0059] The flow rate sensor detects the flow rate of the permeated water supplied to the post-treatment filter 43 .

[0060] The EC / temperature sensor detects the electrical conductivity and temperature of the permeate supplied to the post-treatment filter 43. In addition, the sensor unit 62 may have a sensor that senses at least one of the sensors (1) to (7) shown in the sensor unit 61, in addition to the above sensors.

[0061] The drain tank 45 (second tank) is disposed downstream of the two-way electromagnetic valve 75. The drainage tank 45 is a tank for storing the drainage water to be supplied. The drainage tank 45 can be detached from the purification unit 40 and taken out from the access hole 4. The drainage tank 45 receives concentrated water that has been separated by the reverse osmosis membrane 42 and passed through the two-way electromagnetic valve 75. The drainage tank 45 stores the concentrated water that flows in.

[0062] A water level sensor is disposed in the drainage tank 45. The water level sensor detects the water level of the drainage water stored in the drainage tank 45. The water storage tank 46 (third tank) is disposed after the post-treatment filter 43. The water storage tank 46 is a tank for storing the supplied water.

[0063] Water that has been post-treated by the post-treatment filter 43 flows into the water storage tank 46. Hypochlorous acid water has been added to the water that flows into the water storage tank 46. The water storage tank 46 stores the water that has been added with hypochlorous acid water. A water level sensor is disposed in the water storage tank 46. The water level sensor detects the level of water stored in the water storage tank 46.

[0064] The purification unit 40 includes a chlorine tank 67 and a chlorine pump 68 . The chlorine tank 67 is a tank for storing hypochlorous acid water. The hypochlorous acid water is generated, for example, by dissolving a hypochlorous acid tablet in water supplied to the chlorine tank 67. Alternatively, the hypochlorous acid water may be generated by dissolving salt in water supplied to the chlorine tank 67 and electrolyzing the salt water. In addition, an electrolysis unit that performs electrolysis on saline water to generate hypochlorous acid water may be provided separately downstream of the chlorine tank 67.

[0065] A water level sensor is disposed in the chlorine tank 67. The water level sensor detects the water level of the hypochlorous acid water stored in the chlorine tank 67. The chlorine pump 68 is disposed downstream of the chlorine tank 67. The chlorine pump 68 is operated under the control of the control unit 60, and adds hypochlorous acid water stored in the chlorine tank 67 to the water that has been post-treated by the post-treatment filter 43.

[0066] Inside the housing 2, a drug tank 50 and a drug pump 51 are provided.

[0067] The chemical pump 51 is disposed after the chemical tank 50. The chemical pump 51 is operated under the control of the control unit 60, and delivers the chemical (e.g., soapy water, etc.) stored in the chemical tank 50 to the nozzle of the dispenser 14.

[0068] Specifically, the control unit 60 operates the drug pump 51 in response to detection of an object by the infrared sensor 52 of the dispenser 14. For example, the control unit 60 operates the drug pump 51 while an object is detected by the infrared sensor 52. The control unit 60 stops the drug pump 51 when the object is no longer detected by the infrared sensor 52.

[0069] The drug tank 50 is a tank for storing a drug. A water level sensor is disposed in the drug tank 50. The water level sensor detects the water level of the drug stored in the drug tank 50. When the water level of the drug falls below a predetermined value, the drug is replenished.

[0070] <Configuration of the External Module 7> FIG. 3 is a front view of the external module 7 shown in FIG. 1. As shown in FIG. 3, the external module 7 has a pretreatment filter 41, a post-treatment filter 43, and a UV sterilization device 80.

[0071] The pretreatment filter 41 and the post-treatment filter 43 are arranged side by side outside the housing 2. More specifically, the pretreatment filter 41 and the post-treatment filter 43 are arranged side by side horizontally outside the housing 2.

[0072] The attachment portion 82 of the pretreatment filter 41 and the attachment portion 83 of the post-treatment filter 43 are integrally formed with the UV sterilization device 80. The UV sterilization device 80 is connected above the attachment portion 82 and the attachment portion 83. The pretreatment filter 41 is removably attached to the attachment portion 82. The post-treatment filter 43 is removably attached to the attachment portion 83.

[0073] The pretreatment filter 41 and the post-treatment filter 43 are stored in a container with permeability and a visible interior. Therefore, the pretreatment of water by the pretreatment filter 41 and the post-treatment of water by the post-treatment filter 43 are visible from the outside. In the pretreatment by the pretreatment filter 41, turbid water can be visually confirmed. Also, in the post-treatment by the post-treatment filter 43, it can be visually confirmed that the water is purified into clean water.

[0074] <Configuration of the UV Sterilization Device 80> The UV sterilization device 80 (sterilization device) has a function of irradiating ultraviolet rays to the user's carried items to sterilize the surfaces of the carried items. Examples of the user's carried items include (1) items worn on the user's body such as glasses and watches, (2) items held by the user's hand and used for other items or devices such as keys and cards (for example, keys used to lock or unlock a door, cards with a communication chip built in for communicating with a payment device, etc.), (3) devices operated by the user's hand such as smartphones, and the like. In this embodiment, a smartphone carried by a user is taken as an example of a portable item. The UV sterilization device 80 is provided outside the housing 2 as a part of the external module 7.

[0075] As shown in FIG. 1A, the UV sterilization device 80 is disposed on a side surface of the housing 2. The UV sterilization device 80 has an insertion port 81 that opens upward. A user inserts a smartphone through the insertion port 81. Here, the UV sterilization device 80 may open in another direction, such as to the side, in addition to opening upward as shown in the figure.

[0076] When a smartphone is inserted through insertion port 81 and placed on a base (not shown) inside UV sterilization device 80, UV sterilization device 80 lowers the base and pulls the smartphone into the inside of UV sterilization device 80. A lid (not shown) is closed when the base is lowered to a predetermined position inside the UV sterilization device 80. When the lid is closed, the UV sterilization device 80 turns on the ultraviolet light source (lamp).

[0077] In this case, the light source may irradiate ultraviolet light in a direction toward a specific area of ​​the smartphone that is likely to be particularly dirty, such as the vicinity of the home button or the central area of ​​the display. The specific position may be set statistically based on typical examples of smartphone operation.

[0078] The predetermined position may also be set based on the operation log of the smartphone that is inserted. In this way, by concentrating the ultraviolet light on a particularly dirty area, it is possible to shorten the time required for sterilization.

[0079] For example, the hand-washing device 1 may communicate with a user's carried item (for example, a device with a communication function such as a smartphone) to obtain information about the carried item or information about the user.

[0080] Specifically, (1) when the hand-washing device 1 is provided with a communication unit that communicates with a smartphone or the like via short-range wireless communication (NFC (Near Field Communication) using an IC chip or the like, high-speed wireless communication standard, etc.), the user first places the smartphone in a predetermined position on the hand-washing device 1 before sterilizing the smartphone with the UV sterilization device 80 in the hand-washing device 1. This causes the smartphone to transmit predetermined information to the hand-washing device 1.

[0081] Here, the specified information may include information on the model of the smartphone, information on the attributes of the smartphone user (for example, an employee code if the user is an employee, etc., an age group of the user if the user is a general consumer, membership number information if registered for a service provided by a store, etc., information used when processing payments (user identification information for the payment application, credit card information, etc.), and an operation log of the user's operation of the smartphone (coordinates of contact with the touch screen, application operation history, etc.). In this way, the user may be able to set the range in which information is provided from the smartphone to the hand-washing device 1), etc., and the like may be read by the hand-washing device 1.

[0082] Also, (2) the hand-washing device 1 is managed by an external server or the like and is capable of communicating with the external server or the like. A two-dimensional code such as a QR code (registered trademark) containing information for identifying the hand-washing device 1 (for example, a URL containing the identification information of the hand-washing device 1) is attached to the hand-washing device 1 or displayed on the screen. The two-dimensional code is read by a user's smartphone, and the smartphone communicates information including the identification information of the hand-washing device 1 with the external server or the like, so that the external server or the like can transmit information such as the model of the smartphone to the hand-washing device 1.

[0083] In addition, (3) if the hand-washing device 1 has a reading unit (such as an optical scanner) that reads a two-dimensional code (including information about the smartphone model) displayed on a smartphone or the like, the user may display the two-dimensional code on the smartphone screen and have the hand-washing device 1 read it.

[0084] As described above, an example in which the hand washing device 1 and the smartphone communicate wirelessly has been described. (4) The hand washing device 1 may be directly connected to a smartphone or the like. The hand-washing device 1 may determine the range of the smartphone to be irradiated with ultraviolet light by the UV sterilization device 80 based on the information of the smartphone model. For example, the hand-washing device 1 may preferentially irradiate with ultraviolet light the position of the home button on the smartphone (the size of the smartphone and the position of the home button are determined depending on the smartphone model), the area from the bottom to the center of the screen when the user operates the smartphone in portrait mode (the area where the user's fingers frequently touch when the user operates the smartphone in portrait mode), and the areas near the left and right sides of the screen when the user operates the smartphone in landscape mode, compared to other areas. For example, when the time for sterilization by the UV sterilization device 80 (time for ultraviolet light irradiation) is set to a fixed time in conjunction with the time for hand-washing, the hand-washing device 1 may determine the area to be preferentially irradiated by the UV sterilization device 80 within the fixed time as described above.

[0085] The hand-washing device 1 may also determine the time for hand-washing and the time for sterilization by the UV sterilization device 80 based on information on the attributes of the user. For example, when the hand-washing device 1 is used by an employee or other related person of the facility where the hand-washing device 1 is installed, the hand-washing device 1 may read the information of the related person, and the hand-washing time and the time for sterilization by the UV sterilization device 80 may be set according to the attributes of the related person. Some users may be in a profession that is expected to involve a lot of contact with people, and may particularly require hand-washing and sterilization of their belongings. In this way, the hand-washing device 1 transmits a log of the time when the employee washed their hands and sterilized their belongings with the hand-washing device 1 to an external server or the like. If the external server or the like manages entry and exit to the facility, entry and exit may be controlled based on the history of the user washing their hands with the hand-washing device 1. For example, there may be some rooms where the user can enter even if they have not washed their hands with the hand-washing device 1, and there may be other rooms where the user cannot enter if they have not washed their hands. In this way, the facility manager can restrict entry and exit based on the history of the user washing their hands with the hand-washing device 1.

[0086] The UV sterilization device 80 turns on the UV light for a preset period of time and then turns off the UV light. The preset period of time corresponds to, for example, a commonly recommended time for hand washing. When the UV light is turned off, the UV sterilization device 80 opens the cover and raises the base to a predetermined position. The predetermined position refers to a position where a part of the smartphone protrudes from the insertion port 81 so that the smartphone can be touched by the user. This allows the user to insert and remove the smartphone without touching the UV sterilization device 80 while sterilizing the smartphone. The hand-washing device 1 may be configured to discharge water from the water outlet 13 in response to a user placing a portable item on the UV sterilization device 80. This may prevent the user from forgetting to sterilize the portable item with the UV sterilization device 80.

[0087] A sterilization indicator 16 (second indicator) is disposed on the upper surface of the housing 2, outside the hand-washing basin 11. The sterilization indicator 16 displays the progress of the sterilization process of the UV sterilization device 80 on the carried items.

[0088] The sterilization indicator 16 is disposed on a portion of the top plate 10 that is located between the hand-washing basin 11 and the UV sterilization device 80 when viewed from above. The sterilization indicator 16 is, for example, a circular indicator lamp when viewed from above. The sterilization indicator 16 is configured with an LED light. The lighting state of the sterilization indicator 16 and the control process will be described later.

[0089] <Control process of hand washing device 1> Next, a description will be given of the control process of the hand-washing device 1. Fig. 6 is an explanatory diagram showing the control process of the hand-washing device 1.

[0090] (Water discharge process of the water discharge unit 20) First, the water discharge process from the faucet 12 in the water discharge unit 20 will be described. As shown in FIG. 6, the control unit 60 turns off the water discharge pump 21 (step S11).

[0091] The control unit 60 determines whether or not an object has been detected by the infrared sensor 23 (step S12). When using the hand-washing device 1, the user places his / her hand in the hand-washing basin 11 and causes the infrared sensor 23 disposed at the tip of the faucet 12 to detect the hand and fingers.

[0092] In response to the detection of the finger by the infrared sensor 23 (YES in step S12), the control unit 60 operates the water discharge pump 21 (step S13). The discharge pump 21 passes the water stored in the water storage tank 46 through the UV sterilization unit 22. The UV sterilization unit 22 sterilizes the water discharged from the discharge pump 21 by irradiating the water with ultraviolet rays. The water that has passed through the UV sterilization unit 22 is discharged from the outlet 13 of the faucet 12 as cleaning water. On the other hand, in step S12, if the infrared sensor 23 does not detect a finger (NO in step S12), the water discharge pump 21 does not operate (step S11).

[0093] The control unit 60 determines whether or not an object has been detected by the infrared sensor 23 (step S14). When the user wants to end the hand-washing device 1 or to cause the dispenser 14 to dispense the medicine, the user moves his or her fingers away from the infrared sensor 23 disposed at the tip of the faucet 12. The control unit 60 stops the water discharge pump 21 (step S11) in response to non-detection of a finger by the infrared sensor 23 (NO in step S14).

[0094] On the other hand, in step S14, if the infrared sensor 23 does not detect the finger (YES in step S14), the control unit 60 continues to operate the water discharge pump 21 (step S13). The water discharge unit 20 repeats these processes to discharge flush water from the faucet 12. The control unit 60 may stop the discharge of water when the hand is detected for a certain period of time by measuring the time that the infrared sensor 23 detects the hand. Furthermore, the control unit 60 may stop the discharge of water in response to the completion of sterilization by the UV sterilization device 80 while discharging water.

[0095] (Drainage treatment of drainage unit 30) Next, the drainage treatment in the drainage unit 30 will be described. As shown in FIG. 6, when there is no drainage from hand-washing basin 11, drainage pump 32 is stopped (Step S21). Then, when the wash water discharged from faucet 12 toward hand-washing basin 11 is drained from drain outlet 17 of hand-washing basin 11, capacitance sensor 31 detects the drainage (step S22).

[0096] When the capacitance sensor 31 detects drainage (YES in step S22), the control unit 60 operates the drainage pump 32 (step S23). On the other hand, if the capacitance sensor 31 does not detect drainage (NO in step S22), the control unit 60 does not operate the drainage pump 32 (step S21).

[0097] In step S23, the drain pump 32 sends out wastewater to the pre-treatment filter 41. The water that has been pre-treated in the pre-treatment filter 41 flows into the intermediate tank 44 and is stored in the intermediate tank 44. The pressure sensor 33 detects the pressure of the water sent to the pre-treatment filter 41. The flow rate sensor 34 detects the flow rate of the water that has been pre-treated in the pre-treatment filter 41.

[0098] After step S23, when the capacitance sensor 31 detects that no more wastewater is flowing in from the drain outlet 17 (NO in step S24), the control unit 60 stops the drain pump 32 (step S21). On the other hand, in step S24, if the capacitance sensor 31 detects that wastewater continues to flow in from the drain outlet 17 (YES in step S24), the control unit 60 continues to operate the drain pump 32 (step S23).

[0099] The drainage unit 30 repeats these processes, and supplies the water discharged from the drain outlet 17 of the hand-washing basin 11 to the pre-treatment filter 41.

[0100] (Control process of purification unit 40) Next, the cleaning process in the purification unit 40 will be described. As shown in FIG. 6, initially, the membrane filtration pump 47 is stopped (step S31).

[0101] The control unit 60 determines whether the drain pump 32 is operating (step S32). If the drainage pump 32 is operating (YES in step S32), the control unit 60 operates the membrane filtration pump 47 (step S33). As a result, the water stored in the intermediate tank 44 is supplied to the reverse osmosis membrane 42 at high pressure by the membrane filtration pump 47.

[0102] On the other hand, when the drainage pump 32 is not operating (NO in step S32), the control unit 60 keeps the membrane filtration pump 47 not operating (step S31).

[0103] In step S33, the water supplied to the reverse osmosis membrane 42 is separated into concentrated water and permeated water by the reverse osmosis membrane 42. The permeated water is supplied to the post-treatment filter 43. The concentrated water flows into the intermediate tank 44 through the two-way electromagnetic valve 74. The concentrated water does not flow into the drain tank 45 because the two-way electromagnetic valve 75 is in a closed state.

[0104] In the post-treatment filter 43, post-treatment is performed on the permeated water. Then, the permeated water that has been post-treated in the post-treatment filter 43 flows into the water storage tank 46 after hypochlorous acid water is added thereto.

[0105] After step S33, the control unit 60 determines whether the electrical conductivity detected by the EC / temperature sensor of the sensor unit 61 arranged upstream of the reverse osmosis membrane 42 is less than a predetermined value (step S34). If the electrical conductivity detected by the EC / temperature sensor is less than the predetermined value (YES in S34), the control unit 60 determines whether the drainage pump 32 is operating (step S35). If the drainage pump 32 is operating (YES in step S35), the control unit 60 continues to operate the membrane filtration pump 47 (step S33).

[0106] On the other hand, in step S34, when the electrical conductivity detected by the EC / temperature sensor becomes equal to or greater than the predetermined value (NO in step S34), the control unit 60 turns on the two-way solenoid valve 74 and the two-way solenoid valve 75 (step S36). As a result, the two-way solenoid valve 74 is closed and the two-way solenoid valve 75 is opened.

[0107] By closing the two-way solenoid valve 74 and opening the two-way solenoid valve 75, the concentrated water separated by the reverse osmosis membrane 42 flows into the drain tank 45 via the two-way solenoid valve 75. That is, the control unit 60 determines the amount of impurities in the concentrated water based on the change in electrical conductivity detected by the EC / temperature sensor. Concentrated water determined to have a large amount of impurities is discharged into the drain tank 45.

[0108] When the water level of the concentrated water stored in drainage tank 45 reaches a predetermined value, an alert is issued, for example, to a manager of hand-washing device 1. When the manager confirms the alert, he or she discards the water stored in drainage tank 45.

[0109] The control unit 60 continues the process of step S36 for a predetermined time (step S37), and after the predetermined time has elapsed, turns off the two-way solenoid valves 74 and 75. As a result, the two-way solenoid valve 74 is opened and the two-way solenoid valve 75 is closed. In this manner, the two-way solenoid valve 74 is opened and the two-way solenoid valve 75 is closed, so that the concentrated water separated by the reverse osmosis membrane 42 flows into the intermediate tank 44 through the two-way solenoid valve 74. Then, the control unit 60 stops the membrane filtration pump 47 (step S31).

[0110] In step S35, when the drainage pump 32 is stopped (NO in step S35), the control unit 60 stops the membrane filtration pump 47 (step S31) after a predetermined time has elapsed (step S38).

[0111] The purification unit 40 repeats these processes, purifying the water drained by the drainage unit 30 and storing it in the water storage tank 46.

[0112] (Process for removing water from the water tank 46) Next, the process of removing the water from the water tank 46 will be described. The hand-washing device 1 is portable, and its installation location can be changed as needed. When the hand-washing device 1 is to be transported, the water in the water storage tank 46 is removed to reduce the weight of the hand-washing device 1 in order to facilitate the transport operation. In addition, regardless of whether or not a transportation operation is performed, the water in the water storage tank 46 is removed when the hand-washing device 1 is stored for a long period of time, when the hand-washing device 1 is closed, etc.

[0113] The hand-washing device 1 can be switched between a first state for a user to wash their hands and a second state for removing water from the water tank 46. The first state represents a state in which the water outlet 13 of the faucet 12 is located above the hand-washing basin 11. On the other hand, the second state represents a state in which the water outlet 13 of the faucet 12 is located above and outside the housing 2. When removing the water from the water storage tank 46, the water discharge unit 20 is operated in the second state.

[0114] Specifically, with the water outlet 13 of the faucet 12 positioned above and outside the housing 2, the manager causes the infrared sensor 23 of the faucet 12 to detect fingers. When the infrared sensor 23 detects fingers, the control unit 60 operates the water discharge pump 21 of the water discharge unit 20, causing water to be discharged from the faucet 12.

[0115] The administrator maintains the detection of the hand and drains all of the wash water in the water tank 46 from the water outlet 13, thereby emptying the water tank 46. In the second state, the control unit 60 may directly operate the discharge pump 21 without using the infrared sensor 23 of the faucet 12, thereby discharging all of the flush water in the water storage tank 46 from the discharge port 13.

[0116] The first state and the second state may be switched manually or automatically. For example, in the first state, the manager manually moves the water outlet 13 of the faucet 12 located above the hand-washing basin 11 to an upper position outside the housing 2. When the hand-washing device 1 is in the first state, in response to the water outlet 13 of the faucet 12 being moved to an upper position outside the housing 2, the hand-washing device 1 may transition from the first state to the second state. Also, for example, the administrator inputs a predetermined command in the first state, whereupon the water outlet 13 of the faucet 12 located above the hand-washing basin 11 automatically moves to the outside of the housing 2 and upward.

[0117] Also, the output of notifications such as errors may be changed depending on whether the hand-washing device 1 is in the first state or the second state. For example, when the hand-washing device 1 is in the first state, if the water storage tank 46 or the like does not have a certain amount of water or more so that the user can wash their hands from the water outlet 13 of the faucet 12, an error may be notified by causing the hand-washing indicator 15 to emit a predetermined light, while when the hand-washing device 1 is in the second state, an error may not be notified even if the remaining amount in the water storage tank 46 or the like falls below a certain amount.

[0118] Also, the manner in which water is discharged from water outlet 13 of faucet 12 may be changed depending on whether hand-washing device 1 is in the first state or the second state. For example, when hand-washing device 1 is in the first state, if a certain time has passed since water was discharged from water outlet 13, water discharge may be stopped even if infrared sensor 23 detects the user's fingers (water may be discharged for hand-washing within a certain time), but when hand-washing device 1 is in the second state, water discharge from water outlet 13 may not be stopped regardless of the passage of time.

[0119] <Display mode and control process of hand-washing indicator 15> Next, a description will be given of the display mode and control process of hand-washing indicator 15. Fig. 7 is a diagram for explaining the display mode of hand-washing indicator 15. Fig. 8 is an explanatory diagram showing the control process of hand-washing indicator 15.

[0120] As shown in FIG. 8, when the hand-washing device 1 is not in use, the LED light constituting the hand-washing indicator 15 is turned off (step S41). Next, control unit 60 determines whether dispenser 14 has been operated (step S42). When a user using hand-washing device 1 holds his / her hand under dispenser 14, infrared sensor 52 of dispenser 14 detects the hand. When infrared sensor 52 detects the hand, control unit 60 operates drug pump 51 to eject drug from dispenser 14. When dispenser 14 is operating (YES in step S42), control unit 60 turns on hand-washing indicator 15 (steps S43 to S44).

[0121] Specifically, the control unit 60 turns on the 30 LED lights constituting the hand-washing indicator 15 in order clockwise from the LED light located near the base of the faucet 12 in top view as shown in Fig. 7A. At this time, the control unit 60 turns on all the LED lights in about 1 to 2 seconds, for example.

[0122] Then, as shown in Fig. 7B, when all the LED lights are turned on (step S44), the control unit 60 maintains the turned-on state for a predetermined time thereafter. After the predetermined time has elapsed, the control unit 60 turns off the LED lights in clockwise order starting from the LED light located near the base of the faucet 12 as shown in Fig. 7C (step S45). At this time, the control unit 60 controls so that all the LED lights are turned off in about 30 to 40 seconds, for example.

[0123] The hand-washing device 1 may detect the user's fingers with the infrared sensor 23 and sequentially turn off the hand-washing indicators 15 over time as described above in response to the discharge of water from the water outlet 13. This allows the hand-washing indicators 15 to change their illuminated state as water is discharged from the water outlet 13, allowing the user to recognize the time from the discharge of water to the completion of hand-washing. In addition, when the hand-washing device 1 does not detect a user's hands or fingers using the infrared sensor 23, it may notify users around the hand-washing device 1 to encourage them to wash their hands by, for example, lighting up the hand-washing indicator 15 in a predetermined manner (such as by emitting light in a predetermined color).

[0124] Then, as shown in FIG. 7D, when all the LED lights are turned off (step S45), the process returns to the initial state (step S41). The time taken for the hand-washing indicators 15 to turn on and off in sequence is set to a generally recommended hand-washing time, for example, about 40 seconds, so that the hand-washing device 1 can present the user with a rough guide for the hand-washing time that can be expected to produce a sufficient washing effect.

[0125] <Display mode and control process of the sterilization indicator 16> Next, a description will be given of the display mode and control process of hand-washing indicator 15. Fig. 9 is a diagram for explaining the display mode of hand-washing indicator 15. Fig. 10 is an explanatory diagram showing the control process of hand-washing indicator 15.

[0126] As shown in Fig. 10, when UV sterilizer 80 is not in use, the LED light constituting sterilization indicator 16 is turned off (step S51). When no personal belongings are inserted into UV sterilizer 80, sterilization indicator 16 remains turned off (NO in step S52 in Fig. 10).

[0127] Then, as shown in Fig. 9A, when a portable item (smartphone) is inserted into insertion port 81 of UV sterilizer 80 and the portable item is pulled into UV sterilizer 80 (YES in step S52), controller 60 causes the LED light constituting sterilization indicator 16 to flash (step S53) as shown in Fig. 9B. At this time, controller 60 causes the LED light to flash in red, for example.

[0128] As time passes since the LED light started blinking, control unit 60 shortens the cycle at which the LED light blinks (step S54). The sterilization process in UV sterilization device 80 corresponds to the control of sterilization indicator 16. In other words, control unit 60 speeds up the blinking as the sterilization process in UV sterilization device 80 progresses.

[0129] When the sterilization process in UV sterilizer 80 is finished, as shown in Fig. 9D, controller 60 lights up the LED light in a color different from the previous blinking color (step S55). The LED light lights up in green, for example. This lighting indicates the end of the sterilization process. When the sterilization process is completed and the UV light is turned off, the UV sterilization device 80 opens the cover and raises the user's carried items to a position where they can be removed.

[0130] Then, when the carried item is removed from the insertion slot 81 (YES in step S56), the control unit 60 turns off the LED light (step S51). On the other hand, if the carried item is not removed from the insertion opening 81 (NO in step S56), the control unit 60 maintains the LED light on (step S55). By maintaining the LED light on in this manner, it is possible to prevent the user from forgetting to remove the carried item from the insertion opening 81.

[0131] The processing time of the sterilization process by the UV sterilization device 80 may be the same as or equivalent to the lighting time of the hand-washing indicator 15. In this way, the time of the user's hand-washing and the time of the sterilization process by the UV sterilization device 80 can be associated with each other. This helps to avoid situations where users who have just finished washing their hands have to wait extra for the UV sterilization process to finish.

[0132] As described above, according to the hand washing device 1 of this embodiment, in the hand washing device 1 equipped with a circulation unit 6 that purifies wastewater from the hand washing basin 11 and circulates it as cleaning water, the water outlet 13 of the faucet 12 can be positioned above the hand washing basin 11 or above outside the housing 2. Therefore, by positioning the water outlet 13 of the faucet 12 above and outside the housing 2 and operating the pump of the circulation unit 6, it is possible to discharge the wash water to the outside of the hand-washing device 1.

[0133] That is, for example, there is no need to perform tasks such as attaching a hose to the tip of the faucet 12 or removing the water storage tank 46, which has a certain weight, from inside the housing 2. This makes it possible to easily remove the flush water in the water storage tank 46 and reduce the difficulty of moving it.

[0134] Furthermore, since the housing 2 has a cylindrical shape, the hand-washing device 1 can be easily transported by rolling it while keeping the housing 2 tilted at an angle.

[0135] Furthermore, when a drum can is used as the housing 2, it is possible to ensure design while keeping manufacturing costs down.

[0136] In addition, the housing 2 may be transported by rolling it by placing the exercise portion on the road surface. In this case, in order to make it easier to roll the housing 2 on the road surface, the pre-treatment filter 41, the post-treatment filter 43, the UV sterilizer 80, and other devices installed outside the housing 2 as shown in FIG. 1B may be detachable from the housing 2. This makes it easier for staff of the business operator who installs the housing 2 (for example, the office floor of a business company, store staff, etc.) to change the position of the housing 2 by themselves without having to operate a specialized transportation staff to move the housing 2. For example, the housing 2 is installed near the entrance of a store to have customers wash their hands with the hand-washing device 1 before entering the store. In this case, depending on the location where the housing 2 is installed, a situation may occur in which it is difficult for users visiting the store to find it (and therefore difficult to increase the number of customers who wash their hands before entering the store). In contrast, in the above example, the store's management staff can search for a good location to install the housing 2 in order to provide customers with an environment to wash their hands.

[0137] In addition, access holes 4 are provided on the outer peripheral surface of housing 2. Therefore, access holes 4 can be used to easily perform maintenance of hand-washing device 1, such as disposing of concentrated water with many impurities stored in drainage tank 45 or replacing reverse osmosis membrane 42.

[0138] In addition, a door 3 is provided at the access hole 4. Therefore, by keeping the door 3 closed during normal use, the appearance of the housing 2 can be improved.

[0139] Furthermore, since the hand-washing device 1 is equipped with the hand-washing indicator 15, it is possible to provide a high washing effect by suggesting an appropriate hand-washing time to the user when using the hand-washing device 1. Furthermore, the use of the hand-washing device 1 can educate users on the appropriate hand-washing time.

[0140] Furthermore, since the hand-washing indicator 15 is disposed on the upper surface of the housing 2, outside the hand-washing basin 11, visibility of the hand-washing indicator 15 for a user washing their hands using the hand-washing basin 11 can be ensured.

[0141] In addition, hand-washing indicator 15 is formed on the upper edge of hand-washing basin 11 so as to surround hand-washing basin 11. Therefore, when hand-washing indicator 15 is lit, it is possible to exhibit excellent design.

[0142] In addition, the post-processing filter 43 is disposed outside the housing 2 and is stored in a container whose inside can be seen. Therefore, the user can see from the outside the state of the permeated water filtered by the post-processing filter 43.

[0143] This allows the user to visually confirm that the washing water is being properly cleaned by the circulation unit 6, giving the user a sense of security regarding the cleaning water purification function of the circulation unit 6.

[0144] The pre-treatment filter 41 is also disposed outside the housing 2 and stored in a container whose interior can be seen. This allows the wastewater flowing into the pre-treatment filter 41 to be compared with the purified water flowing out of the post-treatment filter 43. This makes it possible to more effectively provide the user with a sense of security.

[0145] In addition, the circulation unit 6 includes an intermediate tank 44, a drain tank 45, a water storage tank 46, a water discharge unit 20, and a drain unit 30. This allows the intermediate water generated during the cleaning process of the drainage to be appropriately separated and stored.

[0146] In addition, the hand-washing device 1 is equipped with a UV sterilization device 80, so the user can sterilize their own portable items while washing their hands. Generally, portable items such as smartphones that are always carried and operated with the hands tend to have a high rate of bacteria on their surfaces, and habitual sterilization is required for hygiene reasons. Sterilizing the surface of the smartphone with the UV sterilization device 80 can solve this problem.

[0147] In addition, the UV sterilization device 80 is disposed on the side surface of the housing 2. This makes it easier for a user who uses the hand-washing device 1 to wash their hands to insert a portable item into the UV sterilization device 80.

[0148] Moreover, the UV sterilization device 80 is disposed as a part of the external module 7 that is attached to the outside of the housing 2. This improves the appearance of the housing 2. Furthermore, a separate installation for attaching only the UV sterilization device 80 to the housing 2 is not required.

[0149] Furthermore, the hand-washing device 1 is provided with a sterilization indicator 16. This makes it possible to present the progress of the sterilization process to the user, thereby ensuring user convenience.

[0150] Furthermore, the sterilization indicator 16 is disposed outside the hand-washing basin 11 on the upper surface of the housing 2. This ensures that the sterilization indicator 16 is easily visible to the user.

[0151] In addition, the sterilization indicator 16 is disposed between the hand-washing basin 11 and the external module 7. This makes it easier for a user who has washed their hands in the hand-washing basin 11 to check the progress of the sterilization process performed by the UV sterilization device 80. This makes it possible to further ensure convenience for the user.

[0152] In addition, a step of operating the membrane filtration pump 47 is executed when the drainage pump 32 is operating. Therefore, membrane filtration processing can be performed by the reverse osmosis membrane 42 according to the generation of wastewater. This makes it possible to balance the flow rate of circulating water in the entire circulation system while the capacity of each tank is limited. Also, it becomes possible to perform purification processing efficiently.

[0153] Further, the pre-processing filter 41 and the post-processing filter 43 are stored in visible containers and disposed outside the housing 2. When the membrane filtration pump 47 is operating while the drainage pump 32 is operating, the user can simultaneously check from outside how the drainage pump 32 is operating, causing wastewater to flow into the pre-treatment filter 41, and how the membrane filtration pump 47 is operating, causing permeated water to flow into the post-treatment filter 43.

[0154] This allows the user to visually see how the circulating water is cleaning and circulating inside the housing 2, allowing the user to use the hand-washing device 1 with peace of mind.

[0155] <Modification> Next, a description will be given of a modified hand washing device 1. In this modified example, the control unit 60 has a function of automatically controlling the faucet 12 between the first state and the second state.

[0156] In this modification, a motor capable of rotating the faucet 12 is provided at the base of the faucet 12. Then, in response to an external input to the control unit 60, the control unit 60 drives the motor to rotate the faucet 12 around the base, thereby switching between the first state and the second state.

[0157] In the first state, the control unit 60 performs the drainage process, the flushing process, and the water discharge process as described above. On the other hand, in the second state, the control unit 60 operates the water discharge unit 20 without performing drainage and flushing processes, and executes a water discharge process, which is a step of discharging water from the faucet 12 to remove water stored in the water tank 46.

[0158] According to this modification, the control unit 60 automatically controls the first and second states of the faucet 12. In the first state, the hand-washing device 1 can be used normally. In the second state, the flush water in the water storage tank 46 can be removed. In this way, by automatically controlling the orientation of the faucet 12, the flush water in the water storage tank 46 can be removed even more easily.

[0159] <Other Modifications> Next, other modifications will be described. In the above embodiment, the hand-washing device 1 is configured to include the UV sterilization device 80, but the present invention is not limited to this configuration. The hand-washing device 1 does not have to include the UV sterilization device 80. In this case, the hand-washing device 1 does not have the sterilization indicator 16.

[0160] The shape of the housing 2 is not limited to a cylindrical shape and can be changed as desired. For example, the shape of the housing 2 may be an ellipse. The housing 2 can be easily moved by rolling it with one's hand, while preventing it from rolling too far even when released from one's hand.

[0161] In the above embodiment, an example has been described in which one infrared sensor is disposed at the water outlet 13, but the present invention is not limited to this. Four infrared sensors may be disposed in a cross direction at the water outlet 13. This makes it possible to know in which direction a user who has discharged wash water from the water outlet 13 at the start of hand washing moved their hands after wetting them. If it is possible to know the user's actions after wetting their hands, it becomes possible to know whether the user has properly used the medicine.

[0162] The hand-washing device 1 may thus sense how the user moves their hands near the water outlet 13 and store a history of the user's hand movements. By transmitting a log of the user's hand movements to an external server or the like, the hand-washing device 1 can analyze the hand-washing behavior of multiple users who use the hand-washing device 1 in the location where the hand-washing device 1 is installed. For example, it may be possible to analyze whether the hand-washing behavior of users who use the hand-washing device 1 installed in a certain location tends to be appropriate.

[0163] A sensor that determines the presence or absence of a person, such as a human presence sensor, may be disposed on the front surface of the housing 2 of the hand-washing device 1. The human presence sensor makes it possible to obtain the time spent in front of the hand-washing device 1 by a user who has used the hand-washing device 1.

[0164] In the above embodiment, an example has been described in which the pre-processing filter 41 and the post-processing filter 43 are provided outside the housing 2 and housed in a container whose inside is visible, but the present invention is not limited to this embodiment.

[0165] The pre-processing filter 41 and the post-processing filter 43 may be provided inside the housing 2. In this case, the pre-processing filter 41 and the post-processing filter 43 do not need to be stored in a container whose interior is visible.

[0166] The shape, structure, display mode, and control process of the hand-washing indicator 15 may be changed as desired. In addition, the hand-washing device 1 does not necessarily have to include the hand-washing indicator 15.

[0167] It is possible to arbitrarily change the shape, structure, display mode, and control process of the sterilization indicator 16. The sterilization indicator 16 may be provided in the UV sterilization device 80. Moreover, the hand-washing device 1 does not have to be provided with the sterilization indicator 16.

[0168] The configuration of the purification unit 40 can be changed as desired. For example, the post-treatment filter 43 may be omitted, or another filter may be added.

[0169] <Second embodiment> A hand washing device according to the second embodiment will be described. In the second embodiment, maintenance of a hand washing device having a water circulation function will be described. In the description of the second embodiment, the term "hand washing device" includes the "hand washing device 1" described in the first embodiment, and refers to a hand washing device capable of performing maintenance work.

[0170] <Overall composition> A description will be given of the overall configuration of the hand washing device according to the second embodiment. Fig. 11 is a block diagram showing an example of the configuration of the hand washing device according to the second embodiment.

[0171] As shown in Fig. 11, the hand-washing device includes a circulation unit 6, a chemical tank 50, a UV sterilization device 80, and a maintenance unit 9. Although not shown, the hand-washing device naturally includes a housing 2, a hand-washing basin 11 provided in a part of the housing, a faucet 12 that dispenses wash water, a dispenser 14, and the like, as in the first embodiment, to realize hand-washing.

[0172] The configurations of the circulation unit 6, the chemical tank 50, and the UV sterilization device 80 are similar to those in the first embodiment, and therefore will not be described repeatedly.

[0173] Maintenance unit 9 is a structure that controls the maintenance work on the hand-washing device, and is connected to circulation unit 6, chemical tank 50, and UV sterilization device 80. The configuration of maintenance unit 9 will be described below.

[0174] <Maintenance unit configuration> Fig. 12 is a block diagram showing the configuration of the maintenance unit 9. As shown in Fig. 12, the maintenance unit 9 includes a first instructing unit 91, a second instructing unit 92, a storage unit 93, and a maintenance control unit 94.

[0175] The first instruction unit 91 is installed in a position on the housing that is visible to the user, and outputs first instruction information to inform the user of the need for maintenance of the hand-washing device. The need for maintenance here refers to whether or not maintenance work needs to be performed on the hand-washing device. The need for maintenance of the hand-washing device is determined based on the need for maintenance of each maintenance item described below.

[0176] The first indication unit 91 is, for example, configured by the hand-washing indicator 15 of the first embodiment, and is formed on the upper edge of the hand-washing basin so as to surround the hand-washing basin. The first indication unit 91 is also, for example, installed on the outside of the hand-washing basin 11 on the upper surface of the housing 2, and may be, for example, the sterilization indicator 16 of the first embodiment. In other words, the first indication unit 91 is not limited to the above example, as long as it is an indicator installed in a position visible to a user who washes his hands. For example, the first indication unit 91 may be installed in a position near the user on the outside of the hand-washing basin 11 on the upper surface of the housing 2.

[0177] First instruction unit 91 is composed of a light-emitting element and can be lit in a plurality of lighting modes. First instruction unit 91 changes the lighting mode based on the necessity of maintenance and outputs first instruction information. The lighting mode here includes lighting color, lighting brightness, and the presence or absence of blinking. For example, first instruction unit 91 lights up in blue when maintenance of the hand washing device is not necessary, lights up in yellow when the maintenance time will arrive in a predetermined period of time, lights up in red when the maintenance time will arrive soon, and blinks in red when operation has stopped because maintenance was not performed, so as to output the first instruction information.

[0178] In addition, first instruction unit 91 operates when the user is washing his / her hands. For example, first instruction unit 91 is hand-washing indicator 15, which displays an estimate of hand-washing time while the user is washing his / her hands, changes the lighting state based on the necessity of maintenance, and outputs first instruction information.

[0179] First instruction unit 91 notifies the user of the need for maintenance of the hand-washing device, so that the user can grasp the maintenance status or sanitation status of the hand-washing device. In addition, first instruction unit 91 can also notify the manager of the hand-washing device of the need for maintenance, so that the manager can be prompted to perform appropriate maintenance work.

[0180] Second instruction unit 92 is installed inside the housing and outputs second instruction information to inform the user of a maintenance item that requires maintenance. The maintenance item here refers to the maintenance of a component that requires maintenance work among the components of the hand-washing device.

[0181] Specifically, the maintenance items include, for example, at least one of the following items: Replacement of the pre-treatment filter 41, reverse osmosis membrane 42, and post-treatment filter 43 of the circulation unit 6 -Refilling chemical tank 50 with chemicals Disposal of concentrated water stored in the drainage tank 45 Refilling Chlorine Tank 67 with Chlorine ·How to deal with abnormalities in UV sterilizer 80

[0182] The second indication indicates the type of maintenance item that requires maintenance, for example, that a medication needs to be refilled.

[0183] Second instruction unit 92 may be configured so as not to be visible to general users washing their hands during normal use. For example, second instruction unit 92 is a display device that is installed inside housing 2 and can be seen by a manager of the hand-washing device when he or she opens door 3, and displays an identification number of a maintenance item that requires maintenance.

[0184] The second instruction unit 92 is configured with a predetermined display device that can identify and display the maintenance content. For example, the second instruction unit 92 is configured with a 7-segment LED. The second instruction unit 92 identifies and displays the maintenance content by combining the illumination of seven LEDs.

[0185] Furthermore, second instruction unit 92 may be configured with a display device that displays an optical mark informing the user of the maintenance content. The optical mark is a mark that encodes the maintenance content, for example, a barcode, a one-dimensional pixel code, or a two-dimensional pixel code. More specifically, for example, second instruction unit 92 displays a QR code (registered trademark) that corresponds to the maintenance of the hand-washing device. The manager of the hand-washing device reads the QR code with a terminal device that the manager carries. The terminal device displays on a display the maintenance items that require maintenance and the work procedures for performing the maintenance items.

[0186] Second instruction unit 92 can inform the manager of the hand-washing device of specific maintenance items that require maintenance, thereby enabling the manager of the hand-washing device to carry out the maintenance work appropriately.

[0187] The storage unit 93 stores a program according to the second embodiment and data used by a maintenance control unit 94, which will be described later. The data used by the maintenance control unit 94 includes, for example, the following data.

[0188] (a) Parameters for operating the various hardware components of the hand washing device Pump operation parameters (1) Pump drive values ​​(voltage, current), cumulative drive time, and pump maintenance records (2) Pump service life

[0189] -Tank operation control parameters (1) Tank capacity, material, and service life (2) Fluctuations in tank capacity (3) Tank cumulative operating time and maintenance records

[0190] -Valve operation control parameters (1) Valve drive value (voltage, current), cumulative drive time, operation time / timing (2) Valve service life

[0194] User Data (1) User attributes (gender, nationality, place of residence, occupation) (2) User usage history (hand-washing time, frequency)

[0195] Controller Data (1) Manager attributes (gender, nationality, place of residence, industry) (2) Administrator's management history (maintenance history, consumables purchase history)

[0196] In this embodiment, the memory unit 93 stores, for example, hand-washing device usage history data 931, component management data 932, filter sensing data 933, remaining liquid sensing data 934, and sterilization device usage history data 935.

[0197] The hand-washing device usage history data 931 is a database of the usage history of the hand-washing device, which will be described in detail later.

[0198] The component management data 932 is a database that manages the necessity of each maintenance item based on the usage history of the hand washing device. Details will be described later.

[0199] The filter sensing data 933 is a database of sensors that detect the degree of wear of the pre-treatment filter 41, the reverse osmosis membrane 42, the post-treatment filter 43, and the like provided in the circulation unit 6. Details will be described later.

[0200] The remaining liquid level sensing data 934 is a database of sensors that detect the remaining amount of liquid so as to determine the need for refilling or discarding the liquid, as will be described in more detail below.

[0201] Sterilization device usage history data 935 is a database regarding the usage history of the UV sterilization device 80. Details will be described later.

[0202] The maintenance control unit 94 is realized by the processor, memory, etc. of the hand-washing device. The maintenance control unit 94 executes a program stored in the storage unit 93, thereby fulfilling the functions of various modules such as controlling the output of the first instruction unit 91 and the second instruction unit 92.

[0203] The data acquisition module 941 acquires, from the storage unit 93, data used for performing processing to control the outputs of the first instruction unit 91 and the second instruction unit 92. For example, the data acquisition module 941 acquires filter sensing data 933 from the storage unit 93.

[0204] First instruction unit control module 942 performs processing to control the output of first instruction unit 91. For example, first instruction unit control module 942 determines the necessity of maintenance for each maintenance item based on data acquired by data acquisition module 941, and controls the output of first instruction unit 91 by determining the necessity of maintenance of the hand washing device.

[0205] The second instruction unit control module 943 performs processing to control the output of the second instruction unit 92. For example, the second instruction unit control module 943 determines the necessity of maintenance for each maintenance item based on the data acquired by the data acquisition module 941, and controls the output of the second instruction unit 92 by identifying the maintenance items that require maintenance.

[0206] <Data Structure> 13 to 17 are diagrams showing the data structure of the database stored in the maintenance unit 9. FIG. FIG. 13 is a diagram showing the data structure of the hand-washing device usage history data 931.

[0207] As shown in FIG. 13, each record of the hand-washing device usage history data 931 includes information such as the item "Date and Time" and the item "Details."

[0208] The item "Date and Time" is time information when a user uses the hand washing device to wash their hands, and stores the date and time.

[0209] The item "detailed information" is information about the operation of the hand washing device when washing hands, and stores, for example, the water discharge of the hand washing device, the medicine discharge, and the duration of water discharge. For example, the maintenance control unit 94 recognizes a series of actions of water discharge, medicine discharge, and water discharge that are close in time as one hand washing session.

[0210] Using the hand-washing device usage history data 931, the maintenance control unit 94 can grasp, for example, the number of times the hand-washing device has been discharged, the number of times medicine has been discharged, and the number of times the hand-washing has been performed.

[0211] FIG. 14 is a diagram showing the data structure of the component management data 932. As shown in FIG.

[0212] As shown in FIG. 14, each record of the component management data 932 includes information such as the item “component identification information,” the item “last maintenance date and time,” the item “usable number of hand washings,” the item “number of hand washings since last maintenance,” and the item “remaining number of hand washings.”

[0213] The item "member identification information" is information for identifying the member corresponding to each maintenance item, and stores the name and identification number of the member. Note that it is also acceptable to store only the identification number.

[0214] The item "Last maintenance date and time" stores information about the time when the most recent maintenance was performed on the member corresponding to each maintenance item, including the date and time.

[0215] The item "durable number of hand-washings" is the number of hand-washings that can be performed from immediately after maintenance is performed until the next maintenance time for the component corresponding to each maintenance item, and is information based on the attributes of each component. For example, if 50 hand-washings can be performed from immediately after the pre-treatment filter is replaced until the next replacement is required, "50 times" is stored as the "durable number of hand-washings" of the pre-treatment filter. The item "durable number of hand-washings" may be preset for each component, or the number may be rewritten when the program for the hand-washing device is updated.

[0216] The item "number of hand washings since last maintenance" is information regarding the number of hand washings performed since the last maintenance for the components corresponding to each maintenance item. The item "number of hand washings since last maintenance" is determined based on hand washing device usage history data 931. For example, based on hand washing device usage history data 931, the number of times the medicine has been discharged from the medicine tank since the date and time of the last maintenance is accumulated and stored as the "number of hand washings since last maintenance" for the medicine tank.

[0217] The item "remaining number of hand-washings" is information about the remaining number of hand-washings that can be performed until the next maintenance period for the component corresponding to each maintenance item. The item "remaining number of hand-washings" is a value obtained by subtracting the item "number of hand-washings since the last maintenance" from the item "usable number of hand-washings." For example, if the pre-treatment filter can be used for 50 hand-washings with one replacement and 30 hand-washings have been performed since the last replacement, "20 times" is stored as the "remaining number of hand-washings."

[0218] When a component corresponding to a maintenance item is replaced, the maintenance control unit 94, for example, reads out identification information from the replaced component. The identification information of the component is stored, for example, in a wireless tag. The maintenance control unit 94 reads out the identification information stored in the wireless tag, for example, using a reader function. The identification information of the component may also be stored, for example, in a memory installed in the component. When the component is attached, the maintenance control unit 94 accesses the memory and reads out the stored identification information.

[0219] The maintenance control unit 94 adds the read identification information to a new record in the item "component identification information" of the component management data 932. At this time, the maintenance control unit 94 judges whether the read identification information complies with a predetermined rule. The predetermined rule may be changed depending on the release date of the component. If the read identification information does not comply with the predetermined rule, the maintenance control unit 94 notifies the person replacing the component that the replaced component is not appropriate.

[0220] Using the member management data 932, the maintenance control unit 94 can, for example, grasp the usage status of each member and grasp the remaining number of hand washings that can be performed until the next maintenance period arrives.

[0221] FIG. 15 is a diagram showing the data structure of the filter sensing data 933. As shown in FIG.

[0222] As shown in FIG. 15, each record of the filter sensing data 933 includes information such as an item "sensor identification information", an item "date and time", an item "sensing result", and the like.

[0223] The item "sensor identification information" is information for identifying each sensor, and stores the name and identification number of the sensor. Note that only the identification information may be stored. The sensors include sensors installed in the flow path of each filter of the circulation unit 6, i.e., sensors installed in the upstream or downstream of each filter, specifically, the pressure sensor 33, the sensor unit 61, the sensor unit 62, etc.

[0224] The item "date and time" is time information when each sensor performed sensing, and stores the date and time.

[0225] The item "Sensing results" is the detection results obtained by sensing with each sensor, and indicates the water pressure, flow rate, electrical conductivity, etc., before or after the filter.

[0226] The maintenance control unit 94 determines the degree of wear of each filter based on, for example, the sensing results of each sensor. For example, an EC / temperature sensor installed downstream of the reverse osmosis membrane 42 detects the electrical conductivity of the circulating water filtered by the reverse osmosis membrane 42 to determine the amount of impurities. In addition, when the pressure or flow rate exceeds a predetermined value, it determines that the reverse osmosis membrane 42 is clogged and needs to be replaced.

[0227] Using the filter sensing data 933, the maintenance control unit 94 can, for example, determine the degree of wear of each filter and the need to replace each filter.

[0228] FIG. 16 is a diagram showing the data structure of the remaining liquid level sensing data 934. As shown in FIG.

[0229] As shown in FIG. 16, each record of the remaining liquid level sensing data 934 includes information such as the item "member identification information", the item "date and time", and the item "sensing result".

[0230] The item "member identification information" is information for identifying the member that stores each liquid, and stores the name and identification number of the member. Note that only the identification information may be stored. The liquid includes the chemical stored in the chemical tank 50, the water stored in the intermediate tank 44, the concentrated water stored in the drainage tank 45, the water stored in the water storage tank 46, and the hypochlorous acid water stored in the chlorine tank 67.

[0231] The item "date and time" is time information when each sensor performed sensing, and stores the date and time. The sensor may be a water level sensor that is installed in each storage member and detects the remaining amount of liquid.

[0232] The item "Sensing result" is the detection result obtained by sensing of each sensor, and indicates the water level of the liquid in each storage member.

[0233] The maintenance control unit 94 grasps the remaining amount of each liquid based on the sensing result of each water level sensor, for example, and determines the need for refilling or discarding. For example, when the sensing result of the water level sensor provided in the medicine tank falls below a predetermined value, it determines that the medicine needs to be refilled.

[0234] Using the remaining liquid level sensing data 934, the maintenance control unit 94 can, for example, determine the remaining amount of each liquid and determine the need for refilling or discarding each liquid.

[0235] FIG. 17 is a diagram showing the data structure of the sterilization device usage history data 935.

[0236] As shown in FIG. 17, each record of the sterilization device usage history data 935 includes information such as the item "member identification information," the item "date and time," and the item "ultraviolet radiation pattern."

[0237] The item "component identification information" is information for identifying a sterilization device, and stores the name and identification number of the component. Note that only the identification information may be stored. The sterilization device includes a UV sterilization device 80.

[0238] The item "Date and Time" is time information when the UV sterilization device 80 is operating, and stores the date and time.

[0239] The item "ultraviolet ray irradiation pattern" is information indicating the manner in which the UV sterilization device 80 irradiates ultraviolet ray. Examples of the "ultraviolet ray irradiation pattern" include a pattern in which the UV sterilization device 80 irradiates ultraviolet ray all over the user's carried items, a pattern in which the UV sterilization device 80 irradiates ultraviolet ray in a concentrated manner on a predetermined area, and an abnormal state in which ultraviolet ray cannot be irradiated. The maintenance control unit 94 obtains, for example, information related to the usage history from the UV sterilization device 80.

[0240] The sterilization device usage history data 935 enables the maintenance control unit 94 to grasp, for example, the operating status of the sterilization device and to grasp any abnormal state of the sterilization device.

[0241] <Operation> The operation of controlling the first instruction section and the second instruction section by the maintenance unit will be described below. FIG. 18 is a diagram showing a flow of a process for controlling the first instruction unit 91 and the second instruction unit 92. As shown in FIG.

[0242] In step S181, the maintenance control unit 94 acquires, for each maintenance item, the date and time of the maintenance, the number of hand-washings that can be tolerated from immediately after the maintenance until the next maintenance time, and the number of hand-washings since the previous maintenance. Specifically, the maintenance control unit 94 acquires the above information from the hand-washing device usage history data 931 and the member management data 932.

[0243] In step S182, the maintenance control unit 94 calculates the remaining number of hand washings that can be performed until the next maintenance time for each maintenance item. The maintenance control unit 94 calculates the remaining number of hand washings by subtracting the number of hand washings since the previous maintenance from the durable number of hand washings.

[0244] In step S183, the maintenance control unit 94 determines the output modes of the first and second instruction units based on the remaining number of hand-washing times. Specifically, the maintenance control unit 94 determines the necessity of maintenance for each maintenance item based on the remaining number of hand-washing times for each maintenance item, and further determines the necessity of maintenance for the hand-washing device.

[0245] For example, the maintenance control unit 94 extracts the minimum value from the remaining number of hand-washing times for each maintenance item. If the extracted minimum value is 15 times or more, the maintenance control unit 94 determines that the necessity of maintenance for each maintenance item and the hand-washing device is "no maintenance required."

[0246] Furthermore, when the minimum value is less than 15 times and is 5 times or more, the maintenance control unit 94 determines that the necessity of the maintenance item corresponding to the minimum value and the maintenance of the hand washing device is "preparation for maintenance."

[0247] Furthermore, if the minimum value is less than 5 times and is equal to or greater than 1 time, the maintenance control unit 94 determines that the maintenance item corresponding to the minimum value and the necessity of maintenance of the hand washing device are "maintenance required."

[0248] Furthermore, the maintenance control unit 94 stops the operation of the hand washing device when the minimum value is 0. The maintenance control unit 94 determines the necessity of the maintenance item corresponding to the minimum value and the maintenance of the hand washing device as "will not restart unless maintenance is performed."

[0249] In step S184, the maintenance control unit 94 causes the first and second instruction units to output the first and second instruction information in the output mode determined in step S183.

[0250] Specifically, if it is determined in step S183 that the necessity for each maintenance item and for maintenance of the hand-washing device is "no maintenance required," maintenance control unit 94, for example, lights up first indication unit 91 in blue and displays information indicating that maintenance is not required in second indication unit 92. For example, second indication unit 92 displays identification number "00," indicating that maintenance is not required.

[0251] Furthermore, in step S183, if the need for maintenance of the maintenance item corresponding to the minimum value and the hand washing device is determined to be “maintenance preparation”, the maintenance control unit 94, for example, lights up the first indication unit 91 in yellow and displays the identification number of the maintenance item in question in the second indication unit 92.

[0252] Furthermore, in step S183, if it is determined that the maintenance item corresponding to the minimum value and the need for maintenance of the hand washing device are "maintenance required," the maintenance control unit 94, for example, lights up the first indication unit 91 in red and displays the identification number of the maintenance item in question on the second indication unit 92.

[0253] Furthermore, in step S183, if it is determined that the maintenance item corresponding to the minimum value and the necessity for maintenance of the hand washing device are such that "the device will not restart unless maintenance is performed," the maintenance control unit 94, for example, causes the first indication unit 91 to flash in red and displays the identification number of the maintenance item in question on the second indication unit 92.

[0254] The threshold value for the remaining number of times is not limited to the above-mentioned 15 times and 5 times, and may be larger or smaller than these. In addition, the alerts are issued in stages, such as "No maintenance required", "Preparing for maintenance", "Maintenance required", and "No restart unless maintenance is performed", but the stages of alerts are not limited to these. The number of stages may be more or less than these.

[0255] In addition, when the minimum value becomes 0, the operation of the hand-washing device is stopped, but the operation of the hand-washing device does not necessarily have to be stopped when the minimum value becomes 0. For example, the hand-washing device may be allowed to be used several times even after the minimum value becomes 0. If the device continues to be used without maintenance being performed after the minimum value becomes 0, the maintenance control unit 94 more strongly urges maintenance to be performed.

[0256] 18 shows an example in which the first and second instruction units are controlled based on the remaining number of hand-washing times, but this is not limiting. The first and second instruction units may be controlled as follows. Any of the control processes may be used, or multiple control processes may be used in combination.

[0257] (A) Control based on filter wear A sensor for detecting at least one of the flow rate, pressure, temperature, and electrical conductivity of water passing through the filter is provided in the flow path of the filter to detect the degree of wear of the filter. The maintenance unit 9 controls the outputs of the first indicator 91 and the second indicator 92 based on the degree of wear of the filter.

[0258] For example, the maintenance control unit 94 acquires the sensing results of each sensor from the filter sensing data 933 and determines the degree of wear of the pre-treatment filter 41, the reverse osmosis membrane 42, the post-treatment filter 43, etc., provided in the circulation unit 6. For example, when the electrical conductivity detected by an EC / temperature sensor installed downstream of the reverse osmosis membrane 42 exceeds a predetermined value, the maintenance control unit 94 determines that the reverse osmosis membrane 42 is clogged and needs to be replaced. The maintenance control unit 94 lights up the first indication unit 91 in red and displays the identification number corresponding to the reverse osmosis membrane 42 on the second indication unit 92.

[0259] Furthermore, when a predetermined behavior, for example, a behavior indicating an abnormality in the filter, occurs in the sensing result acquired from the filter sensing data 933, the maintenance control unit 94 determines that an abnormality has occurred in the pre-treatment filter 41, the reverse osmosis membrane 42, the post-treatment filter 43, etc., provided in the circulation unit 6. The maintenance control unit 94 lights up the first indication unit 91 in red, and displays on the second indication unit 92 the identification number corresponding to the corresponding filter.

[0260] (a) Control based on remaining amount of liquid A sensor for detecting the water level is provided in the container for storing the liquid to detect the remaining amount of the liquid. The maintenance unit 9 controls the outputs of the first indicator 91 and the second indicator 92 based on the remaining amount of the liquid.

[0261] For example, a water level sensor that detects the remaining amount of the drug is provided in the drug tank 50, and when the sensing result of the water level sensor falls below a predetermined value, the maintenance control unit 94 determines that the drug needs to be replenished. The maintenance control unit 94 lights up the first indication unit 91 in red, and displays the identification number corresponding to the drug tank 50 on the second indication unit 92.

[0262] (c) Control based on abnormality detection results of sterilization equipment A detection means is provided to detect an abnormality occurring in the sterilization device. The maintenance unit 9 controls the outputs of the first instruction section 91 and the second instruction section 92 based on the detection of an abnormality in the sterilization device.

[0263] For example, the maintenance control unit 94 obtains the usage history of the UV sterilization device 80 from the UV sterilization device 80. When an abnormality in the ultraviolet radiation irradiation of the UV sterilization device 80 is detected, the maintenance control unit 94 determines that maintenance of the UV sterilization device 80 is required. The maintenance control unit 94 lights up the first indication unit 91 in red, and displays the identification number corresponding to the UV sterilization device 80 in the second indication unit 92.

[0264] Furthermore, for example, the maintenance control unit 94 obtains the usage history of the UV sterilization unit 22 from the UV sterilization unit 22. When the UV sterilization unit 22 reports that an abnormality has occurred in the irradiation of ultraviolet rays, the maintenance control unit 94 determines that maintenance of the UV sterilization unit 22 is required. The maintenance control unit 94 lights the first indication unit 91 in red and displays the identification number corresponding to the UV sterilization unit 22 on the second indication unit 92.

[0265] Through the above series of processes, maintenance unit 9 can properly notify information regarding the maintenance of the hand-washing device through first instruction unit 91 and second instruction unit 92. This enables the maintenance staff to properly and efficiently perform the maintenance of the hand-washing device.

[0266] It should be noted that the detection of the occurrence of an abnormality by the maintenance unit 9 is not limited to the above. When a predetermined behavior, for example, a behavior indicating an abnormality in the water discharge unit 20, the drainage unit 30, or the purification unit 40 occurs in the sensing result acquired from the filter sensing data 933, the maintenance control unit 94 determines that an abnormality has occurred in the water discharge unit 20, the drainage unit 30, or the purification unit 40. The maintenance control unit 94 lights up the first indication unit 91 in red, and displays the identification number corresponding to the corresponding unit on the second indication unit 92.

[0267] <Display example> Display examples of the first indicator 91 and the second indicator 92 will be described.

[0268] Fig. 19 is a diagram showing an example of a display mode of the first indicator 91. In Fig. 19, the first indicator 91 is configured by the hand-washing indicator 15 of the first embodiment, and while displaying an estimate of the hand-washing time while the user is washing his / her hands, notifies the user of the need for maintenance of the hand-washing device in different lighting modes.

[0269] For example, when the hand-washing device does not require maintenance, the hand-washing indicator 15 lights up in blue, and when the hand-washing device requires maintenance, the hand-washing indicator 15 lights up in red. As shown in Fig. 19, when the dispenser 14 is operating, the hand-washing indicator 15 lights up in clockwise order starting from the LED light located near the base of the faucet 12 in a top view to indicate an approximate hand-washing time, and also lights up in a predetermined color to notify the user of the need for maintenance of the hand-washing device.

[0270] This allows the user to be notified of the need for maintenance of the hand-washing device in a manner that is easily visible to the user while washing his or her hands. This allows the user to grasp the maintenance status or sanitation status of the hand-washing device. In addition, the need for maintenance can be notified to the manager of the hand-washing device, which can encourage the manager to perform maintenance work appropriately.

[0271] Fig. 20 is a diagram showing an example of a display mode of the second indicator 92. In Fig. 20, the second indicator 92 is made up of two 7-segment LEDs, and notifies the user of the maintenance item requiring maintenance by displaying the identification number of the maintenance item.

[0272] 20, when it is determined that replacement of the pre-processing filter 41 is necessary, the second indication unit 92 displays the identification number "02" of the pre-processing filter 41. When there is no maintenance item that requires maintenance, the identification number "00" may be displayed. When a technical error occurs that cannot be solved by replacement or the like, for example, a preset identification number "88" may be displayed.

[0273] This allows the manager of the hand-washing device to be informed of specific maintenance items that require maintenance, allowing the manager to carry out the maintenance work appropriately.

[0274] Furthermore, the maintenance control unit 94 may determine whether or not a replaced component, for example, a filter, is proper, based on the item "sensing result" of the filter sensing data 933. For example, the flow rate characteristics of the pre-treatment filter 41, the reverse osmosis membrane 42, and the post-treatment filter 43 change depending on the materials used. In other words, the pressure or flow rate detected in the upstream or downstream of the filter changes depending on the materials used.

[0275] The maintenance unit 9 stores in advance in the memory unit 93 a general pressure value or flow rate value, etc., detected when the proper pre-treatment filter 41, reverse osmosis membrane 42, and post-treatment filter 43 are installed, with a predetermined range. When the filter is replaced, the maintenance control unit 94 controls, for example, the water discharge unit 20 to discharge wash water from the faucet 12. The maintenance control unit 94 judges whether the pressure value or flow rate value detected at this time falls within the range of the preset pressure value or flow rate value. If it does not fall within the range, the maintenance control unit 94 notifies the person who replaced the replaced member that the replaced member is not proper. The preset pressure value or flow rate value, etc. may be updated to the latest value when the program is updated.

[0276] <Third embodiment> Next, a third embodiment will be described. In the third embodiment, collection of data related to hand washing will be described. Note that the same components as those in the first and second embodiments are given the same reference numerals and will not be described.

[0277] <Overall configuration of information processing system 1000> 21 is a block diagram showing the overall configuration of the information processing system 1000. The information processing system 1000 is a system for collecting and analyzing data such as data related to hand washing, data related to applications, and data related to maintenance.

[0278] As shown in FIG. 21, the information processing system 1000 includes a hand-washing device 1, an information processing device 200, a monitoring device 300, and a maintenance terminal 400. The information processing system 1000 may be configured to include multiple hand-washing devices 1. The hand-washing device 1, the information processing device 200, the monitoring device 300, and the maintenance terminal 400 are connected to a network 500 using a wired or wireless communication standard. The hand-washing device 1 and the information processing device 200 are connected to each other so that they can communicate with each other via the network 500. In this embodiment, the information processing system 1000 includes the monitoring device 300 and the maintenance terminal 400, but the information processing system 1000 does not necessarily have to include the monitoring device 300 and the maintenance terminal 400.

[0279] The hand-washing device 1 is a portable device that can be installed anywhere and allows a user to wash their hands. The hand-washing device 1 includes a communication unit 100. The communication unit 100 is configured to control communication with an information processing device 200.

[0280] The communication unit 100 acquires first data, which is data related to hand washing, and transmits it to the information processing device 200. The first data includes, for example, data on the usage history of the hand washing device 1, data obtained by monitoring the hand washing device 1 acquired from the monitoring device 300, aggregated data created based on the detected data, and other data. The communication unit 100 also acquires second data, which is data related to maintenance, and transmits it to the information processing device 200. The second data includes, for example, data detected by a group of sensors installed in the hand washing device 1, data managing replacement parts, and the like.

[0281] The monitoring device 300 is a device that monitors the surroundings of the hand-washing device 1. The monitoring device 300 is installed in a position that allows monitoring of the surroundings of the hand-washing device 1. For example, the monitoring device 300 may be a camera or the like that is placed in the space where the hand-washing device 1 is installed (such as the lobby or entrance of a building). When the hand-washing device 1 is installed in a space used by unspecified users, the monitoring device 300 may be a monitoring camera or the like that is installed in advance in the space, or may be a device that is installed according to the installation location of the hand-washing device 1. The monitoring device 300 is realized by an imaging device such as a camera, or a sensor such as a human sensor or an infrared sensor. The monitoring device 300 transmits the acquired monitoring data, for example, image data or sensor data, to the hand-washing device 1. By photographing the area around the hand-washing device 1 with a camera, it is possible to determine based on the captured image whether the user is washing their hands properly (for example, whether each step of (1) wetting the hands, (2) applying the medicine to the skin, (3) massaging the hands, and (4) rinsing them off is being performed. Alternatively, as shown in the "Hand-washing Evaluation" section described below, an infrared sensor attached to the hand-washing device 1 etc. can be used to evaluate how the user moves their hands when washing their hands), whether there is a malfunction (described below), whether maintenance is needed (the hand-washing device 1 outputs (e.g., emits light) an indication that maintenance is needed, etc.), and by sensing the area around the hand-washing device 1 with a sensor such as a human presence sensor, it is possible to obtain information such as whether a person is in front of the hand-washing device 1 and how many seconds they stayed in front of the hand-washing device 1 while washing their hands. The monitoring device 300 may also be configured to detect the size of the user's hands from a sensor or monitoring image data of handwashing. In this case, the monitoring device 300 transmits the detected hand size to the handwashing device 1. The control unit 60 according to the first embodiment, for example, ejects an amount of medicine according to the detected hand size. Note that the monitoring data may be transmitted from the monitoring device 300 to the handwashing device 1, and the hand size may be detected by the handwashing device 1. Also, instead of detecting the hand size directly, the hand size may be estimated from the user's attributes such as height, sex, age, etc.

[0282] The maintenance terminal 400 is a device owned by a person in charge of maintenance of the hand-washing device 1. For example, the maintenance terminal 400 is a mobile terminal such as a smartphone, tablet, or laptop PC, or a stationary computer. When a maintenance person performs maintenance, the maintenance terminal 400 transmits second data, which is data related to the maintenance, to the information processing device 200. The maintenance terminal 400 may also input setting data to the hand-washing device 1. The setting data includes, for example, reference data for detecting an abnormality in the circulation unit 6, the number of times a replaceable part can be used, a threshold value for determining the necessity of maintenance (for example, the number of times a replaceable part is used, a threshold value for comparing with an evaluation value of the quality of water purified by a filter, etc.), information for confirming whether the replaceable part is a genuine part (information assigned to a genuine part, etc.), a distance for an infrared sensor to detect the separation of the user's fingers, a threshold value used to control the hand-washing device 1, or a reference value.

[0283] The information processing device 200 acquires first data transmitted from the hand-washing device 1 and second data transmitted from the hand-washing device 1 or the maintenance terminal 400, and stores the acquired data. The information processing device 200 analyzes the stored data. The information processing device 200 may be composed of one or more devices, and each of the multiple devices may be responsible for a function and perform processing, thereby being recognized as a single information processing device.

[0284] <Configuration of communication unit 100> 22 is a block diagram showing a functional configuration of the communication unit 100. As shown in FIG. 22, the communication unit 100 includes a communication section 110 and a communication control section 120.

[0285] The communication unit 110 performs processing for the hand-washing device 1 to communicate with external devices.

[0286] The communication control unit 120 is realized by a processor, a memory, etc. of the hand-washing device 1. The communication control unit 120 performs the functions of a reception control module 121, a transmission control module 122, a data acquisition module 123, an input module 124, and a setting module 125 so as to communicate with the information processing device 200 by executing a program according to the third embodiment stored in the storage unit 93 described in the second embodiment.

[0287] The reception control module 121 controls the process in which the communication unit 100 receives a signal from an external device in accordance with a communication protocol. The reception control module 121 may receive setting data from the information processing device 200 via the network 500.

[0288] The transmission control module 122 controls the process in which the communication unit 100 transmits a signal to an external device according to a communication protocol. Specifically, the transmission control module 122 transmits the first data related to hand washing or the second data related to maintenance to the information processing device 200.

[0289] Data acquisition module 123 acquires data to be transmitted to information processing device 200 from storage unit 93. For example, data acquisition module 123 acquires hand-washing device usage history data 931, member management data 932, filter sensing data 933, remaining liquid sensing data 934, or sterilizer usage history data 935 from storage unit 93. Data acquisition module 123 may aggregate the acquired data for each predetermined period to create aggregated data. The predetermined period is, for example, one day, one week, etc. The aggregated data includes, for example, the number of hand-washings performed during the predetermined period, the amount of medicine used during the predetermined period, etc. Furthermore, data acquisition module 123 acquires monitoring data acquired by monitoring device 300 and stored in storage unit 93.

[0290] The input module 124 accepts the input of setting data from the maintenance terminal 400 .

[0291] The setting module 125 performs settings related to the control of the hand-washing device 1 based on the input setting data.

[0292] <Configuration of information processing device 200> 23 is a block diagram showing a hardware configuration of the information processing device 200. As shown in FIG. 23, the information processing device 200 includes a processor 201, a memory 202, a storage 203, a communication IF 204, and an input / output IF 205.

[0293] The processor 201 is hardware for executing an instruction set written in a program, and is composed of an arithmetic unit, a register, peripheral circuits, and the like.

[0294] The memory 202 is for temporarily storing programs and data to be processed by the programs, and is, for example, a volatile memory such as a DRAM.

[0295] The storage 203 is a storage device for saving data, such as a flash memory or a HDD.

[0296] The communication IF 204 is an interface for inputting and outputting signals so that the information processing device 200 can communicate with an external device.

[0297] The input / output IF 205 functions as an interface with an input device for receiving input operations from an analyst, and an output device for presenting information to the analyst.

[0298] 24 is a block diagram showing a functional configuration of the information processing device 200. As shown in FIG. 24, the information processing device 200 includes a communication unit 210, a storage unit 230, and a control unit 220.

[0299] The communication unit 210 performs processing for the information processing device 200 to communicate with an external device.

[0300] The control unit 220 functions as a reception control unit 221, a transmission control unit 222, an analysis unit 223, a shaping unit 224, an output unit 225, and a learning unit 226 as a result of the processor 201 of the information processing device 200 performing processing according to a program.

[0301] The reception control unit 221 controls the process in which the information processing device 200 receives a signal from an external device in accordance with a communication protocol.

[0302] The transmission control unit 222 controls the process in which the information processing device 200 transmits a signal to an external device in accordance with a communication protocol.

[0303] The shaping unit 224 extracts desired data from the collected data in accordance with the purpose of analysis by the analysis unit 223, and shapes the extracted data into a form suitable for analysis. Details will be described later.

[0304] The analysis unit 223 analyzes the collected data for various purposes. For example, the analysis unit 223 analyzes the data using the data shaped by the shaping unit 224. For example, the analysis results shown below are generated by the analysis of the analysis unit 223. Details will be described later. (A) Demographics (a) Prevalence of hand washing habits (c) Condition of various filters in hand washing device 1 (D) User trends (E) Location of the malfunction (F) Optimal installation location (G) Formulation of optimal sanitation policies (H) Tendency of users of the space in which the hand washing device 1 is installed (I) A preferable position for placing the hand-washing device 1 in the space in which the hand-washing device 1 is installed

[0305] In addition, the analysis unit 223 acquires data on the user who used the hand-washing device 1, the usage time, the location of a malfunction, etc., based on at least one of the image data and the sensor data received from the communication unit 100.

[0306] The analysis unit 223 also evaluates the analysis results according to the purpose of the analysis. The analysis unit 223 also makes a desired inference based on the analysis results. Details will be described later.

[0307] The output unit 225 outputs the analysis result by the analysis unit 223 .

[0308] The learning unit 226 controls the process of learning or relearning the parameters of various learning models, as will be described in detail later.

[0309] The storage unit 230 stores data and programs used by the information processing device 200. The data used by the information processing device 200 includes, for example, the following data, similar to the storage unit 93 of the hand-washing device 1.

[0387] <Operation> <Data collection by communication unit 100> Next, a data transmission process by the communication unit 100 in this embodiment will be described with reference to Fig. 34. Fig. 34 is a flowchart showing an example of an operation performed when the communication unit 100 transmits data to the information processing device 200.

[0388] In step S111, the communication control unit 120 reads data from the memory unit 93 of the hand-washing device 1. Specifically, the communication control unit 120 reads, for example, at a predetermined timing, a record that has not yet been transmitted to the information processing device 200 from the hand-washing device usage history data 931, the component management data 932, the filter sensing data 933, the remaining liquid sensing data 934, or the sterilization device usage history data 935 stored in the memory unit 93 of the hand-washing device 1. The predetermined timing is, for example, a preset time, or a preset cycle, etc. Furthermore, when a tendency for an abnormality to occur in the circulation unit 6 is observed, the communication control unit 120 reads out the record of the filter sensing data 933 at that time. A case where a tendency for an abnormality to occur in the circulation unit 6 is observed refers to, for example, a case where the maintenance control unit 94 in the second embodiment determines, based on the sensing result acquired from the filter sensing data 933, that an abnormality has occurred in the pre-treatment filter 41, the reverse osmosis membrane 42, the post-treatment filter 43, or the like provided in the circulation unit 6. Furthermore, the communication control unit 120 reads out records such as the hand-washing device usage history data 931 and the filter sensing data 933 added during each predetermined period, and creates aggregated data based on the read out records. The aggregated data may be created by the information processing device 200 based on the data transmitted by the communication control unit 120. Furthermore, the communication control unit 120 reads out, at a predetermined timing, monitoring data that has not yet been transmitted to the information processing device 200 from among the monitoring data stored in the storage unit 93. The predetermined timing is, for example, a preset time or a preset cycle. The timing of reading out the monitoring data may be less frequent than the timing of reading out data from the databases 931-935.

[0389] In step S112, the communication control unit 120 transmits the acquired records of hand-washing device usage history data 931, component management data 932, filter sensing data 933, etc., the monitoring data, and the aggregated data as first data to the information processing device 200. In addition, the communication control unit 120 transmits the acquired records of component management data 932, filter sensing data 933, remaining liquid sensing data 934, etc. as second data to the information processing device 200.

[0390] This enables the hand-washing device 1 to transmit data related to hand-washing (first data) such as the number of times hand-washing was done in a day, the amount of water used in hand-washing, the amount of detergent used in hand-washing, the time taken for hand-washing, information related to dirt, the time when hand-washing was done, and the location information where hand-washing was done to the information processing device 200. In addition, the hand-washing device 1 can transmit data related to maintenance (second data) such as the maintenance date and time, sensing results required for maintenance, items to be replaced, and failure data to the information processing device 200.

[0391] <Data collection by information processing device 200> Next, data collection processing by the information processing device 200 in this embodiment will be described with reference to Fig. 35.

[0392] In step S121, the reception control unit 221 of the information processing device 200 receives the first data and the second data from the communication unit 100.

[0393] Furthermore, the reception control unit 221 receives third data input from a carried item (a communication device such as a smartphone or a smartwatch) via, for example, an application related to the hand-washing device 1. The third data includes data input by the user when using the hand-washing device 1, or data read when the carried item is inserted into the UV sterilization device 80, etc. More specifically, the third data includes personal data of the user registered in advance in the application, and data such as the user's evaluation of hand-washing with the hand-washing device 1 input by the user after using the hand-washing device 1. Note that the third data does not have to be received directly from the user's carried item. The third data may be managed by an external server or the like, and the information processing device 200 may acquire the third data by accessing the server.

[0394] In step S122, the control unit 220 stores the received first data, second data, and third data in a target database stored in the storage unit 230.

[0395] <Analysis of monitoring data of information processing device 200> Next, the monitoring data analysis process by the information processing device 200 in this embodiment will be described with reference to Fig. 36. Fig. 36 is a flowchart showing an example of the operation of the information processing device 200 when analyzing monitoring data.

[0396] In step S131, the analysis unit 223 analyzes at least one of the image data and the sensor data acquired from the monitoring device 300 to acquire information such as the user who used the hand-washing device 1, the usage time, and the location of the malfunction. Specifically, when the analysis unit 223 receives image data from the communication unit 100, the analysis unit 223 performs image analysis on the image data. As a result, the analysis unit 223 extracts the user who used the hand-washing device 1, and estimates the gender, generation (age), time taken for hand-washing of the user, etc. Furthermore, the analysis unit 223 detects faults or failures caused by dirt, damage, etc. of the hand-washing device 1 by performing image analysis on the image data received from the communication unit 100. Furthermore, the analysis unit 223 detects the situation around the hand-washing device 1, such as the number of people, by performing image analysis on the image data received from the communication unit 100. Furthermore, when the analysis unit 223 receives sensor data from the communication unit 100, it analyzes the sensor data. As a result, the analysis unit 223 extracts the user, detects the location of a malfunction or fault, calculates the time the hand-washing device 1 is used, and so on.

[0397] In step S132, the control unit 220 stores the data acquired by the analysis in a target database stored in the storage unit 230.

[0398] <Analysis processing> Next, the analysis process by the information processing device 200 in this embodiment will be described with reference to Fig. 37. Fig. 37 is a flowchart showing an example of the operation of the information processing device 200 when analyzing data.

[0399] First, we will explain the case where the purpose of analysis is (a) to understand demographic trends. In step S141, the shaping unit 224 extracts data corresponding to the analysis purpose from the data stored in each database, and shapes the extracted data into a form suitable for the desired analysis.

[0400] Specifically, for example, the shaping unit 224 extracts data for each item from the installation data DB 232, the aggregated data DB 233, the hand-washing data DB 234, the user data DB 236, etc. The shaping unit 224 selects necessary data from the extracted data, rearranges the data in chronological order, and classifies the data by area.

[0401] In step S142, the analysis unit 223 performs an analysis on hand-washing based on the shaped data. Specifically, for example, the analysis unit 223 acquires, for each of a plurality of areas, a change over time in the number of times the hand-washing device 1 is used, based on the shaped data. The analysis unit 223 compares the change in the number of times the hand-washing device 1 is used for each area. In step S143, output unit 225 outputs the analysis results obtained by analysis unit 223. Specifically, output unit 225 presents the comparison results acquired by analysis unit 223 to the operator of information processing device 200. The operator of information processing device 200 can grasp the demographic trends between areas by referring to the comparison results of the change over time in the number of times of use for each area. In addition, the number of times hand-washing device 1 has been used, the distribution of users who have used hand-washing device 1, etc. may be output as analysis results for each area.

[0402] Next, for example, a case where the purpose of analysis is to understand the prevalence of hand-washing habits (i) will be described. In step S141, for example, the shaping unit 224 extracts data for each item from the installation data DB 232, the aggregated data DB 233, the hand-washing data DB 234, the user data DB 236, the monitoring data DB 239, etc. The shaping unit 224 selects necessary data from the extracted data, rearranges the data in chronological order, and classifies the data by area.

[0403] In step S142, analysis unit 223 acquires, for example, the change over time in the number of times hand-washing device 1 is used and the change over time in the number of users with high hand-washing ratings for each of a plurality of areas based on the shaped data. Analysis unit 223 arranges the data in such a way that the expansion / contraction of areas with high usage and the expansion / contraction of areas with a large number of users with high hand-washing ratings can be grasped. In step S143, the output unit 225 presents the analysis result acquired by the analysis unit 223 to the operator of the information processing device 200. The operator of the information processing device 200 can grasp the prevalence of hand washing habits by referring to the enlargement / reduction of areas with high usage counts and the enlargement / reduction of areas with a large number of users with high hand washing ratings.

[0404] Next, for example, a case where the analysis purpose is (d) grasping the user's tendency will be described. In step S141, for example, the shaping unit 224 extracts data for each item from the installation data DB 232, the aggregated data DB 233, the hand-washing data DB 234, the user data DB 236, the monitoring data DB 239, etc. The shaping unit 224 selects necessary data from the extracted data, rearranges the data in chronological order, and classifies the data by generation, occupation, etc.

[0405] In step S142, the analysis unit 223 acquires hand-washing characteristics for each classified cluster based on, for example, the shaped data, and compares the hand-washing characteristics for each cluster.

[0406] In step S143, the output unit 225 presents the comparison result acquired by the analysis unit 223 to the operator of the information processing device 200. The operator of the information processing device 200 can grasp the tendency of the user of the hand-washing device 1 by referring to the hand-washing characteristics of each cluster.

[0407] The analysis unit 223 may analyze the data using a trained analysis model.

[0408] <Estimation process> Next, the estimation process by the information processing device 200 in this embodiment will be described with reference to Fig. 38. Fig. 38 is a flowchart showing an example of the operation of the information processing device 200 when estimating a predetermined event.

[0409] First, for example, a case where the analysis purpose is (c) grasping the states of various filters of the hand-washing device 1 will be described. In step S141, the shaping unit 224 extracts data corresponding to the analysis purpose from the data stored in each database, and shapes the extracted data into a form suitable for the desired analysis. Specifically, for example, the shaping unit 224 extracts data for each item from the product data DB 231, the installation data DB 232, the aggregated data DB 233, the hand-washing data DB 234, the maintenance data DB 237, the environmental data DB 238, etc. The shaping unit 224 selects necessary data from the extracted data and rearranges the data in chronological order. In step S152, the analysis unit 223 estimates the states of various filters based on the shaped data. Specifically, for example, the analysis unit 223 acquires past sensing results similar to the behavior of the current sensing result based on the shaped data. The analysis unit 223 estimates the wear tendency of the filter by referring to the acquired past sensing results and past maintenance data. In step S153, the output unit 225 outputs the estimation result by the analysis unit 223. Specifically, the output unit 225 presents the wear tendency of the filters estimated by the analysis unit 223 to the operator of the information processing device 200. The operator of the information processing device 200 can grasp the states of various filters by referring to the wear tendency of the filters.

[0410] Next, a case where the analysis purpose is (e) grasping the location of the occurrence of a failure will be described. In step S141, the shaping unit 224 extracts data for each item from, for example, the product data DB 231, the installation data DB 232, the aggregated data DB 233, the hand-washing data DB 234, the maintenance data DB 237, the environmental data DB 238, etc. The shaping unit 224 selects necessary data from the extracted data and rearranges them in chronological order. In step S152, the analysis unit 223 acquires past sensing results similar to the behavior of the current sensing result, for example, based on the shaped data. The analysis unit 223 refers to the acquired past sensing results and past maintenance data to estimate a part at which a failure may occur. In step S153, the output unit 225 presents the part where a failure is likely to occur, which is estimated by the analysis unit 223, to the operator of the information processing device 200. By referring to the part where a failure is likely to occur, the operator of the information processing device 200 can grasp in advance the location where the failure will occur.

[0411] Next, for example, a case where the analysis purpose is (f) grasping the optimal installation location will be described. In step S141, the shaping unit 224 extracts data for each item from, for example, the product data DB 231, the installation data DB 232, the aggregated data DB 233, the hand-washing data DB 234, the maintenance data DB 237, the environmental data DB 238, etc. The shaping unit 224 selects necessary data from the extracted data and rearranges them in chronological order. In step S152, the analysis unit 223 acquires, for example, based on the shaped data, changes over time in the number of times the hand-washing device 1 is used, increases and decreases in the number of times the hand-washing device 1 in the vicinity is used after a specific hand-washing device 1 is installed, etc. The analysis unit 223 compares the acquired trends with the current situation, and estimates areas (locations) where the number of hand-washings is predicted to increase sharply in the future. In step S153, the output unit 225 presents the area estimated by the analysis unit 223 to the operator of the information processing device 200. The operator of the information processing device 200 can grasp the optimal installation location by referring to the presented area.

[0412] Next, we will explain, for example, the case where the purpose of the analysis is to formulate an optimal sanitation policy. In step S141, the shaping unit 224 extracts data for each item from, for example, the product data DB 231, the installation data DB 232, the aggregated data DB 233, the hand-washing data DB 234, the maintenance data DB 237, the environmental data DB 238, etc. The shaping unit 224 also acquires hygiene policies issued in the past by a predetermined local government, the dates of issuance of the hygiene policies, index values ​​representing the hygiene environment, etc. The shaping unit 224 selects necessary data from the extracted data and rearranges them in chronological order. In step S152, the analysis unit 223 obtains a predetermined correlation, for example, based on the shaped data, by comparing changes over time in the index value, etc. after the issuance of the hygiene policy with changes over time in the number of uses, etc. of the hand-washing device 1. The analysis unit 223 applies the obtained correlation to the current situation to estimate a hygiene policy suitable for the current situation. In step S153, the output unit 225 presents the hygiene policy estimated by the analysis unit 223 to the operator of the information processing device 200. The operator of the information processing device 200 can formulate an optimal hygiene policy by referring to the presented hygiene policy.

[0413] The analysis unit 223 may perform the estimation process using a trained model. In this case, the trained model is generated by, for example, a machine learning model learning a predetermined trend as input data and a result highly related to the trend as correct output data.

[0414] <Analysis model learning> Next, the analytical model learning process by the information processing device 200 in this embodiment will be described with reference to Fig. 39. Fig. 39 is a flowchart showing an example of the operation of the information processing device 200 when training an analytical model.

[0415] In step S161, the learning unit 226 acquires data according to the analysis purpose of the analysis model from each database.

[0416] In step S162, the learning unit 226 learns parameters of the analytical model so that an analytical result is output when at least one of the first data, the second data, and the third data is input. In step S163, the learning unit 226 stores the acquired parameters in the storage unit 230.

[0417] <Analysis of users in the space where hand washing device 1 is installed> (h) The information processing device 200 may output, based on information about a user who washes his / her hands using the hand-washing device 1, analysis results showing user tendencies for unspecified users who use the space in which the hand-washing device 1 is installed. For example, the information processing device 200 analyzes the tendency of users who use the hand-washing device 1 (e.g., age group, gender, etc.) based on the user data DB236, the installation data DB232, etc., and outputs the tendency of users of the space in which the hand-washing device 1 is installed as the analysis result. For example, even in a space where a check-in operation for using a facility is not accepted from a user, the hand-washing device 1 can be installed in a store or the like in the facility and the user can use the hand-washing device 1 to analyze the tendency of users who visit the store or the like. For the store or the like, data for analyzing the tendency of users who visit the store or the like can be accumulated through hand-washing with the hand-washing device 1 before the timing when a user who visits the store or the like finalizes a purchase, such as during payment processing. The hand-washing device 1 may also be linked to an information terminal for accepting user information (e.g., a terminal for accepting waiting lists at a store, etc.). For example, in response to accepting input of user information at the information terminal (e.g., inputting user information when visiting a store), a notification may be sent to encourage the user to wash their hands with the hand-washing device 1. Through the above processing, the information processing device 200 may update the user data DB236.

[0418] (i) The information processing device 200 may be placed in a space in which the hand-washing device 1 is installed, and may analyze a preferable position for placing the hand-washing device 1. For example, the information processing device 200 compares the number of users using the space (e.g., by analyzing images captured by the surveillance camera) with the history of users who washed their hands using the hand-washing device 1, based on the video footage from a surveillance camera installed in the space and the history of hand-washing using the hand-washing device 1. Depending on the comparison result (e.g., when the number of times the hand-washing device 1 has been used is small compared to the number of users), the information processing device 200 may notify the user of the information processing device 200 to move the hand-washing device 1 to a location that is easier to use. As described above, the information processing device 200 may provide the function of performing these analyses and the analysis results, etc., to the business that installs the hand-washing device 1. Here, the analysis function that the information processing device 200 provides to the business may be set according to the fee plan in the contract for the business to use the hand-washing device 1.

[0419] As described above, the information processing system according to this embodiment acquires first data related to hand-washing from the hand-washing device 1, which is portable and can be installed anywhere, and transmits the acquired first data to the information processing device 200. The information processing device 200 acquires the first data from the hand-washing device 1, which can be installed anywhere, and stores the acquired first data, making it possible to efficiently collect data related to hand-washing.

[0420] In addition, the hand-washing device is portable and can be installed anywhere, and multiple hand-washing devices may be installed in the information processing system. By configuring in this way, data related to hand-washing can be collected more efficiently.

[0421] In addition, a hand-washing device other than the hand-washing device may be installed so as to be portable and installable at any location, and the hand-washing-related data may be collected more efficiently.

[0422] <Other> Although the preferred embodiment of the present disclosure has been described above, the present disclosure is not limited to the specific embodiment, and the present disclosure includes the invention described in the claims and its equivalents. In addition, the configurations of the devices described in the above embodiments and modifications can be combined as appropriate as long as no technical contradiction occurs.

[0423] In the above embodiment, the communication unit 100, the monitoring device 300, and the maintenance terminal 400 communicate directly with each other, but the present invention is not limited to this. The communication unit 100, the monitoring device 300, and the maintenance terminal 400 may be configured to communicate with each other via a network 500.

[0424] In the above embodiment, the communication unit 100 is configured as an internal function of the hand-washing device 1, but this is not limited to the above. The communication unit 100 may be configured as an external device connected to the hand-washing device 1.

[0425] Furthermore, a collection of devices (e.g., the communication unit 100 and the information processing device 200) constituting the information processing system 1000 can be understood as one “information processing device.” In other words, the information processing system 1000 can be realized as a collection of multiple devices, and the allocation of multiple functions for realizing the information processing system 1000 can be appropriately determined based on the processing capacity of the hardware of each device.

[0426] <Fourth embodiment> A hand washing device according to a fourth embodiment will be described. In the fourth embodiment, management of a hand washing device that is portable and can be installed anywhere will be described.

[0427] The hand-washing device 1A described in this embodiment can be installed in various locations, such as indoors and outdoors. The hand-washing device 1A is installed indoors, for example, near the entrance of a building, in the office space of a business operator occupying the building, near the entrance of a store, etc. It is assumed that the hand-washing device 1A is managed by the manager of the facility in which the hand-washing device 1A is installed.

[0428] <Overall configuration of hand washing device 1A> The overall configuration of the hand-washing device 1A according to the fourth embodiment will be described below. Figure 40 is a rear perspective view of the hand-washing device 1A according to the fourth embodiment.

[0429] The hand-washing device 1A according to the fourth embodiment is configured in the same manner as the hand-washing device 1 according to the first embodiment, except for the housing 2A, horizontal shaft 101, and running wheels 102A and 102B, so a description thereof will be omitted. The housing 2A, horizontal shaft 101, and running wheels 102A and 102B of the hand-washing device 1A will be described below.

[0430] As shown in Figure 40, through holes 24A and 24B are formed in the outer peripheral surface of housing 2A at a position close to the bottom surface of the rear side (door 3 side) of hand-washing device 1A. The axis passing through through holes 24A and 24B is configured to extend parallel to the bottom surface.

[0431] Horizontal shaft 101 is installed so as to penetrate through through holes 24A and 24B and enter the interior of housing 2A. Running wheels 102A and 102B are rotatably attached to both ends of horizontal shaft 101. For example, horizontal shaft 101 is a rod-shaped shaft fixed to housing 2A, and running wheels 102A and 102B are casters attached to both ends of horizontal shaft 101 and capable of moving hand washing device 1A in the forward and backward directions.

[0432] The horizontal shaft 101 and the running wheels 102A and 102B constitute a movement assisting unit that assists the movement of the hand-washing device 1 A. This makes it possible to easily move the hand-washing device, which is portable and can be installed anywhere, and makes it easy to manage the hand-washing device.

[0433] In Fig. 40, the horizontal shaft 101 and running wheels 102A, 102B are arranged on the rear side of the hand-washing device 1A, but this is not limited thereto and they may be arranged in other positions as long as they can assist in the movement of the hand-washing device 1A. Also, the movement assistance unit may be configured by locating only the running wheels 102A, 102B, which are made up of casters, on the bottom surface of the hand-washing device 1A without locating the horizontal shaft 101.

[0434] Although not shown, a convex portion may be provided on the bottom surface of the hand-washing device 1A. The convex portion protrudes so as to contact the floor surface when the running wheels 102A and 102B are in contact with the floor surface. This allows the hand-washing device 1 to stand independently and stably.

[0435] The hand-washing device 1A further includes an installation position indicator that can turn on the hand-washing device 1A in a plurality of lighting modes. The hand-washing device 1A acquires information about a planned installation position of the hand-washing device 1A, and the installation position indicator changes the lighting mode depending on whether the hand-washing device 1A has reached the planned installation position.

[0436] The "planned installation location of the hand-washing device 1A" here may be the installation destination when installing the hand-washing device 1A before installation, or the destination when changing the installation location of the hand-washing device 1A that has already been installed, and refers to an appropriate installation location of the hand-washing device 1A. The information processing device 200A determines the installation destination or destination location. Details will be described later.

[0437] For example, the installation position indicator is configured by the hand-washing indicator 15 of the first embodiment, and when the hand-washing device 1A reaches the intended installation position, the hand-washing indicator 15 lights up in blue, and when the hand-washing device 1A has not reached the intended installation position, the hand-washing indicator 15 lights up in yellow. This allows the user to know whether the hand-washing device is installed in an appropriate position.

[0438] <Overall configuration of information processing system 1000A> 41 is a block diagram showing the overall configuration of information processing system 1000A. Information processing system 1000A is a system for managing hand-washing devices by collecting and analyzing data such as data on the operating time, installation location, and usage history of hand-washing devices.

[0439] As shown in Figure 41, the information processing system 1000A includes a hand-washing device 1A, an information processing device 200A, and a terminal device 600 carried by an installer who installed the hand-washing device 1A (such as a manager of the facility where the hand-washing device 1A is installed). The information processing system 1000A may be configured to include multiple hand-washing devices 1A. The hand-washing device 1A, the information processing device 200A, and the terminal device 600 are connected to each other via a network 500 using a wired or wireless communication standard so as to be able to communicate with each other.

[0440] The hand-washing device 1A is a portable device that can be installed anywhere and allows a user to wash their hands. The hand-washing device 1A is equipped with a communication unit 100A. The communication unit 100A is configured to control communication with an information processing device 200A. Note that, in this embodiment, an example is described in which the hand-washing device 1A is equipped with a movement assistance unit, but the hand-washing device 1A does not need to be equipped with a movement assistance unit as long as it is portable and can be installed anywhere.

[0441] After the hand-washing machine 1A is installed, the communication unit 100A acquires first information on the operating time of the hand-washing machine 1A, second information on the location where the hand-washing machine 1A is installed, and third information on the usage history of the hand-washing machine 1A. The communication unit 100A also acquires information presented by the information processing device 200A. The communication unit 100A is configured in the same way as the communication unit 100 in Fig. 22, and therefore a description thereof will be omitted.

[0442] The information processing device 200A acquires data such as the first information, second information, and third information transmitted from the hand-washing device 1A, and stores the acquired data. The information processing device 200A analyzes the stored data. The information processing device 200A may be composed of one or more devices, and each of the multiple devices may be responsible for a function and perform processing, so that the information processing device 200A is recognized as a single information processing device. In addition, the hardware configuration of the information processing device 200A is the same as that of the information processing device 200 in FIG. 23, so a description thereof will be omitted.

[0443] The terminal device 600 is a device operated by a user who installs and manages each hand-washing device 1A. The terminal device 600 is realized by a mobile terminal such as a smartphone or tablet compatible with a mobile communication system. In addition, the terminal device 600 may be, for example, a stationary PC (Personal Computer) or a laptop PC.

[0444] <Overall configuration of information processing device 200A> Fig. 42 is a block diagram showing a functional configuration of the information processing device 200A. The information processing device 200A is configured similarly to the information processing device 200 shown in Fig. 24 except for the proposal generation unit 227, the information presentation unit 228, the installation data (second information) DB 232A, the aggregated data (third information) DB 233A, and the operating time data (first information) DB 242, and therefore a description thereof will be omitted. The proposal generation unit 227, the information presentation unit 228, the installation data DB 232A, the aggregated data DB 233A, and the operating time data DB 242 will be described below.

[0445] When the operating time of hand-washing machine 1A reaches a preset time, proposal generating unit 227 generates a proposal for change regarding the number or installation locations of hand-washing machines 1A. For example, proposal generating unit 227 creates a proposal for change based on information related to the usage history of hand-washing machine 1A.

[0446] Specifically, for example, the proposal generating unit 227 generates a proposal to install an additional hand washing device near a frequently used hand washing device or to move a relatively less used hand washing device near a frequently used hand washing device based on the usage history of the hand washing device 1A for a predetermined period (e.g., every month) after the hand washing device 1A starts to operate. The proposal generating unit 227 may also generate a proposal to change the installation location of the hand washing device 1A when a period has continued for more than a certain period after the hand washing device 1A starts to operate but the frequency of hand washing is relatively low (e.g., the number of times of hand washing within a predetermined period such as one day is less than a certain number). The proposal generating unit 227 may also generate a proposal to add a hand washing device 1A based on the usage history of the hand washing device 1A when a period has continued for more than a certain period after the hand washing device 1A starts to operate but the frequency of hand washing is relatively low (e.g., the number of times of hand washing within a predetermined period such as one day is more than a certain number). This allows the hand washing device 1A to be arranged according to the demand for hand washing.

[0447] The information presentation unit 228 presents the first information, second information, and third information acquired from each hand-washing apparatus 1A to the terminal device 600 of each installer who installed each hand-washing apparatus 1A. In addition, the information presentation unit 228 presents the proposal generated by the proposal generation unit 227 to the terminal device 600 of each installer who installed each hand-washing apparatus 1A.

[0448] The installation data DB 232A is a database for storing data relating to the location where the hand-washing device 1A is installed, as will be described in detail later.

[0449] The aggregated data DB 233A is a database for holding aggregated data relating to the usage history of the hand-washing device 1A, as will be described in detail later.

[0450] The operation time data DB 242 is a database for storing information on the operation time of the hand-washing device 1A after the hand-washing device 1A is installed, as will be described in detail later.

[0451] <Data Structure> Figures 43 to 45 are diagrams showing data structures of databases stored in the information processing device 200A. Note that Figures 25 to 33 are merely examples, and do not exclude data that is not listed.

[0452] Fig. 43 is a diagram showing an example of the data structure of the installation data DB 232A. As shown in Fig. 43, the records of the installation data DB 232A are configured in the same manner as the installation data DB 232 shown in Fig. 26 except for the item "facility ID" and the item "terminal ID", so the description thereof will be omitted. The item "facility ID" and the item "terminal ID" will be described below.

[0453] The item "Facility ID" stores identification information (ID) for identifying the facility in which the hand-washing device 1A is installed. Each facility is assigned a different ID. The facility ID is used as a key for linking information between other databases. For example, the information processing device 200A extracts various information about one or more hand-washing devices 1A installed in the same facility. Note that the key is not limited to the facility ID, and other information may be used.

[0454] The item "Terminal ID" stores identification information (ID) for identifying the terminal device 600 possessed by a person managing the hand-washing device 1A in a facility or the like where the hand-washing device 1A is installed. Each terminal device 600 is assigned a different ID. For example, the information processing device 200A transmits various information about the hand-washing device 1A to the terminal device 600 corresponding to the hand-washing device 1A and presents it.

[0455] Fig. 44 is a diagram showing an example of the data structure of the aggregated data DB 233A. As shown in Fig. 44, the records of the aggregated data DB 233A are configured in the same manner as the aggregated data DB 233 shown in Fig. 27 except for the item "facility ID", so the description thereof will be omitted. The items "facility ID" and "terminal ID" will be described below.

[0456] The item "Facility ID" stores identification information (ID) for identifying the facility in which the hand-washing device 1A is installed. Each facility is assigned a different ID. The facility ID is used as a key for linking information between other databases. For example, the information processing device 200A extracts various information about one or more hand-washing devices 1A installed in the same facility. Note that the key is not limited to the facility ID, and other information may be used.

[0457] Fig. 45 is a diagram showing an example of a data structure of the operating time data DB 242. As shown in Fig. 45, each record of the operating time data DB 242 includes an item "product ID", an item "facility ID", an item "operating time", and the like.

[0458] The item "Product ID" stores identification information (ID) for identifying the hand-washing device 1A. Each hand-washing device 1 is assigned a different ID. The product ID is used as a key for linking information between other databases. For example, the information processing device 200A extracts various information about each hand-washing device 1A. Note that the key is not limited to the product ID, and other information may be used.

[0459] The item "Facility ID" stores identification information (ID) for identifying the facility in which the hand-washing device 1A is installed. Each facility is assigned a different ID. The facility ID is used as a key for linking information between other databases. For example, the information processing device 200A extracts various information about one or more hand-washing devices 1A installed in the same facility. Note that the key is not limited to the facility ID, and other information may be used.

[0460] The item "operating time" stores information regarding the operating time of the hand-washing device 1A after it has been installed. By acquiring first information regarding the operating time, the information processing device 200A manages the hand-washing device 1A as being in operation. For example, the information processing device 200A counts the operating time of the hand-washing device 1A from the time when an instruction to start the operation of the hand-washing device 1A is received from the hand-washing device 1A, and stores the operating time in days. If the information processing device 200A has not received an instruction to start the operation of the hand-washing device 1A, it stores the hand-washing device 1A as "not operating."

[0461] The "instruction to start operation of hand-washing device 1A" here may be, for example, an operation in which the user turns on the switch of hand-washing device 1A after installing it, or an operation in which the user inputs information to the effect that operation of hand-washing device 1A has been started via terminal device 600, or an operation in which the user properly sets up hand-washing device 1A, attaches a filter, and starts operation. Note that the operating time of hand-washing device 1A is not necessarily related to the installation date of the hand-washing device. For example, if the user installs hand-washing device 1A but does not turn on the switch, information processing device 200A considers the hand-washing device to be not operating.

[0462] This allows information processing device 200A to accurately grasp the operating time of the hand-washing device and present it to the user.

[0463] <Operation> The operation of managing the hand washing device will be described below. FIG. 46 is a diagram for explaining an example of a flow of managing the hand-washing device 1A by the information processing system 1000A according to the fourth embodiment.

[0464] In step S2001, before the hand-washing device 1A is installed, the information processing device 200A presents the planned installation location of the hand-washing device to the terminal device associated with the hand-washing device.

[0465] Specifically, the information processing device 200A determines the "planned installation location" of the hand-washing device 1A based on information about the facility where the hand-washing device 1A will be installed. For example, when other hand-washing devices are installed in the facility, the information processing device 200A identifies a frequently used hand-washing device based on the usage history of the other hand-washing devices, and determines a location near the frequently used hand-washing device as the "planned installation location" of the hand-washing device to be installed. The information processing device 200A may also accept an operation to specify the "planned installation location" of each hand-washing device 1A in advance by the operator of the facility where the hand-washing device 1A will be installed. Even if the "planned installation location" is not specified by the operator, the information processing device 200A may determine the "planned installation location" based on information about the layout of the facility so that the hand-washing devices 1A are distributed and placed at a certain interval or more. For example, it is assumed that attributes of sections in the facility are determined according to the information about the layout (e.g., the area occupied by a store, the area used as an aisle, etc.). The information processing device 200A may determine the "planned installation location" of the hand-washing device 1A based on information on the attributes of the sections in the facility. For example, the information processing device 200A may determine to install the hand-washing device 1A at the boundary between the area occupied by the store and the area used as an aisle, or to install the hand-washing device 1A at a position that serves as an entrance or exit of the area used as an aisle. The information processing device 200A may also receive information regarding changes to the layout of the store, and determine the "planned installation location" of each hand-washing device 1A in response to receiving the information regarding the changes. This allows the information processing device 200A to determine the location where the hand-washing device 1A should be installed in accordance with the information on the changed layout.

[0466] Furthermore, when no other hand-washing devices are installed in the facility, information processing device 200A determines the "proposed installation location" of hand-washing device 1A to be installed based on information on the movement of people in the facility. For example, information processing device 200A determines a location near an exit with a large number of people entering and exiting a department store as the "proposed installation location" of the hand-washing device to be installed based on information on the number of people entering and exiting each exit of a department store.

[0467] Furthermore, if no other hand-washing devices are installed in the facility, information processing device 200A may determine the "proposed installation location" of hand-washing device 1A to be installed based on the usage history of hand-washing devices installed in other facilities with similar attributes to the facility. For example, when hand-washing device 1A is to be installed in a hotel, information processing device 200A determines a location near the hotel reception desk as the "proposed installation location" of hand-washing device 1A to be installed based on the usage history of hand-washing devices installed at the reception desk of other hotels that are frequently used.

[0468] In step S6001, terminal device 600 receives the planned installation location of hand-washing device 1A from information processing device 200A, displays it, and presents it to the user. Details will be described later with reference to FIG.

[0469] In step S1001, after being installed, the hand-washing device 1A acquires and transmits first information regarding the operating time of the hand-washing device 1A, second information regarding the location where the hand-washing device 1A is installed, and third information regarding the usage history of the hand-washing device 1A.

[0470] Regarding the first information, hand-washing device 1A starts acquiring the first information in response to an instruction to start operation of hand-washing device 1A. The "instruction to start operation of hand-washing device 1A" may be, for example, an operation in which a user turns on the switch of hand-washing device 1A after installing hand-washing device 1A, or an operation in which a user inputs information to the effect that operation of hand-washing device 1A has been started via terminal device 600, or an operation in which a user properly sets up hand-washing device 1A, attaches a filter, and starts operation. Information processing device 200A manages hand-washing device 1A as being in operation by acquiring the first information regarding the operation time.

[0471] Regarding the second information, the hand-washing device 1A may detect the location where the hand-washing device 1A is installed by being equipped with a Global Positioning System (GPS). The hand-washing device 1A may acquire the location where the hand-washing device 1A is installed by receiving an operation from the user to input the installation location of the hand-washing device 1A via the terminal device 600. The hand-washing device 1A may be installed at the planned installation location by determining that the terminal device 600 is located at the location where the hand-washing device 1A should be installed based on the GPS of the terminal device 600 or identification information of an access point with which the terminal device 600 communicates, etc.

[0472] The third information includes at least one of the number of times hand washing is performed with the hand washing device 1A, the amount of water used in hand washing, the amount of chemicals used in hand washing, information regarding dirt, and the time when hand washing was performed, and reflects the frequency of use or load of the hand washing device 1A.

[0473] In step S2002, information processing device 200A acquires the first information, the second information, and the third information from hand-washing device 1 A. Information processing device 200A updates the database stored in storage unit 230A based on the acquired first information, second information, and third information.

[0474] The contents of the database stored in memory unit 230A are presented to terminal device 600, for example, in response to a request from terminal device 600. For example, when information processing device 200A is requested by terminal device 600 to display the first information, second information, and third information, the information processing device 200A transmits the first information, second information, and third information for each of multiple hand-washing devices 1A installed in the same facility to terminal device 600. Information processing device 200A may also be configured to transmit the first information, second information, and third information for each of multiple hand-washing devices 1A installed in the same facility to terminal device 600 at a predetermined period.

[0475] For example, the terminal device 600 displays the first information, the second information, and the third information for each of multiple hand-washing devices 1A installed in the same facility on the same screen. Details will be described later in FIG.

[0476] In step S2004, when the operating time of the hand-washing machine 1A reaches a preset time, the information processing device 200A presents a proposal for changing the number or installation locations of the hand-washing machines 1A.

[0477] For example, the information processing device 200A generates a proposal based on the usage history of the hand-washing device 1A at predetermined intervals (e.g., one month) after the hand-washing device 1A starts operating, to install an additional hand-washing device near a hand-washing device that is used frequently, or to move a hand-washing device that is used less frequently to near a hand-washing device that is used frequently, and presents the proposal to the terminal device 600.

[0478] In step S6002, the terminal device 600 displays a proposal for changing the number or installation locations of the hand-washing devices 1A.

[0479] For example, the terminal device 600 displays the installation destination of the hand-washing device 1A to be additionally installed or the movement destination of the hand-washing device 1A already installed, determined by the information processing device 200A. Details will be described later in the drawings. Details will be described later in FIG. 49.

[0480] Through the above series of processes, the information processing device 200A can present information regarding the planned installation location of the hand-washing device 1A to the installer who installed the hand-washing device 1A. The information processing device 200A can also present information regarding the operating time, installation location, and usage history of the hand-washing device 1A to the installer who installed the hand-washing device 1A. The information processing device 200A can also present suggestions for changes to the number or installation locations of the hand-washing devices 1A to the installer who installed the hand-washing device 1A.

[0481] Therefore, the user can grasp the operating status of the hand-washing device 1A, easily manage the hand-washing device, and efficiently consider the installation location of the hand-washing device.

[0482] Furthermore, since the hand-washing device has a movement assistance section, the user can easily move the hand-washing device to an appropriate installation position.

[0483] In addition, in Fig. 46, the operation of managing the hand-washing device 1A is described as a series of operations of the hand-washing device 1A, the information processing device 200A, and the terminal device 600, but is not limited to this. For example, the operation of step S2001 by the information processing device 200A and the operation of step S6001 by the terminal device 600 may be executed independently of Fig. 46. Furthermore, the operation of step S1001 by the hand-washing device 1A and the operation of step S2002 by the information processing device 200A may be executed independently of Fig. 46. Furthermore, the operation of step S2004 by the information processing device 200A and the operation of step S6002 by the terminal device 600 may be executed independently of Fig. 46.

[0484] <Display example> The following describes examples of displays on the terminal device 600. Figures 47 to 49 are diagrams showing examples of screens on the terminal device 600.

[0485] The example screen in Fig. 47 is a diagram showing a situation in which terminal device 600 displays the planned installation location of hand-washing device 1A before the hand-washing device 1A is installed. As shown in Fig. 47, a notification is displayed on the display screen of terminal device 600 to prompt the user to install hand-washing device 1A in a predetermined location.

[0486] For example, based on information on the number of people entering and exiting each exit of a department store, information processing device 200A determines exit E1, which has a large number of people entering and exiting, as the "proposed installation location" of the hand-washing device. Terminal device 600 displays a notification to encourage installation of hand-washing device 1A at exit E1.

[0487] This allows the user to be informed of an appropriate installation location for the hand-washing device 1A before the hand-washing device 1A is installed. Here, the location of the terminal device 600 held by the installer who will install the hand-washing device 1A (i.e., the location of the installer) may be displayed on a screen as shown in the example screen of FIG. 47. The screen may also display a route for the installer to move to the location where the hand-washing device 1A is to be installed. This allows the installer to easily move the hand-washing device 1A to the location where it should be installed, and allows the installation of the hand-washing device 1A to proceed efficiently.

[0488] The example screen of Fig. 48 is a diagram showing a situation in which terminal device 600 displays the operation status of multiple hand-washing devices 1A installed in the same facility after the hand-washing device 1A is installed. As shown in Fig. 48, the first information, second information, and third information of each hand-washing device are displayed on the same screen on the display screen of terminal device 600. Here, the screen may display hand-washing devices 1A that have already started operation (hand-washing devices 1A whose operation time has been updated in operation time data 242) and hand-washing devices 1A that have not yet started operation (hand-washing devices 1A that are not in the planned installation location or have not been operated to update the operation time). This allows the facility operator to easily check the operation status, such as whether hand-washing devices 1A are operating as planned.

[0489] For example, the terminal device 600 displays a map showing the installation locations of each hand-washing device 1A, while also displaying information on the operating time, installation location, and usage history of each hand-washing device 1A on the same screen.

[0490] This allows the operating statuses of multiple hand-washing devices 1A installed in the same facility to be displayed in a manner that is easy for users to visually confirm, allowing the users to grasp the operating statuses of the hand-washing devices 1A and easily manage the hand-washing devices 1A.

[0491] The example screen in Figure 49 is a diagram showing a situation in which terminal device 600 displays a proposal to change the number or location of hand-washing machines 1A. As shown in Figure 49, the display screen of terminal device 600 displays a proposal to add a hand-washing machine 1A to a predetermined location or to move a hand-washing machine 1A to a predetermined location.

[0492] For example, if the hand-washing machine 1A installed at exit E1 is frequently used while the hand-washing machine 1A installed at exit E2 is not used much, the terminal device 600 displays a suggestion to install an additional hand-washing machine 1A at a position near exit E1 or to move the hand-washing machine 1A installed at exit E2 to a position near exit E1.

[0493] This allows appropriate suggestions for changing the number of hand-washing devices or the installation locations in a facility where the hand-washing devices are installed, based on the usage history of the hand-washing devices 1A. Therefore, the user can easily manage the hand-washing devices 1A and efficiently consider the installation locations of the hand-washing devices. In the above example, the hand-washing device 1A is not only transported by human power but also self-propelled. If the hand-washing device 1A is not at the planned installation location, the information processing device 200A may calculate a route for moving the hand-washing device 1A to the planned installation location and automatically travel the hand-washing device 1A along the route. This makes it even easier to change the location of the hand-washing device 1A at any time so that it is placed at an optimal location in accordance with the situation in the facility. In addition, when automatically traveling the hand-washing device 1A, the information processing device 200A may move the hand-washing device 1A at a time when it is expected that there will be few people staying in the facility, such as outside business hours, based on the business hours of the store in which the hand-washing device 1A is installed.

[0494] <Fifth embodiment> Next, a fifth embodiment will be described. In the fifth embodiment, a case will be described in which the hand washing device 1 uses dedicated water. Note that the same components as those in the first, second, third and fourth embodiments will be given the same reference numerals and the description thereof will be omitted.

[0495] <Overall composition> 50 is a block diagram showing an example of the overall configuration of an information processing system according to Embodiment 5. The information processing system 1000B is a system for enabling effective hand-washing using a hand-washing device 1B.

[0496] As shown in Figure 50, the information processing system 1000B includes a hand-washing device 1B, an information processing device 200B, and a terminal device 600. The information processing system 1000B may be configured to include multiple hand-washing devices 1B. The hand-washing device 1B, the information processing device 200B, and the terminal device 600 are connected to a network 500 using a wired or wireless communication standard. The hand-washing device 1B and the information processing device 200B are connected to each other via the network 500 so that they can communicate with each other.

[0497] The hand-washing device 1B is a portable device that can be installed anywhere and allows a user to wash their hands. The hand-washing device 1B includes a circulation unit 6B, a chemical tank 50B, a maintenance unit 9B, and a communication unit 100B. Although not shown, the hand-washing device 1B includes a housing 2, a hand-washing basin 11 provided in a part of the housing, a faucet 12 that dispenses wash water, a dispenser 14, and the like, as in the first embodiment, to realize hand-washing.

[0498] The circulation unit 6B is a unit that purifies and circulates the wash water.

[0499] The chemical tank 50B is a tank for storing a plurality of types of chemicals. The chemical tank 50B has, for example, cartridges filled with chemicals. The chemical tank 50B prepares the chemicals filled in the cartridges based on information about a user of the hand-washing device 1B.

[0500] The maintenance unit 9B is a unit that controls the maintenance work on the hand-washing device 1B. Similar to the maintenance unit 9 shown in FIG. 12, the maintenance unit 9B includes a first instructing unit 91, a second instructing unit 92, a memory unit 93, and a maintenance control unit 94.

[0501] In this embodiment, the maintenance items include, in addition to those described in the second embodiment, for example, Refilling the water conditioning tank 700 with liquids or chemicals - Refilling water tank 46 with special water Includes:

[0502] The maintenance control unit 94 grasps the remaining amount of liquid in the water tank 46 based on, for example, the sensing result of a water level sensor in the water tank 46. When the remaining amount is less than a preset amount, the maintenance control unit 94 displays an instruction on the first instruction unit 91 and the second instruction unit 92 to refill the water tank 46 with dedicated water. In this embodiment, the dedicated water is a liquid for the hand-washing device 1B, and is a liquid that satisfies a predetermined property. The predetermined property is, for example, pH, electrical conductivity, redox potential, alkalinity, ion concentration, viscosity, turbidity, color, odor, or hardness. Satisfying a predetermined property means, for example, that pH, electrical conductivity, redox potential, alkalinity, ion concentration, viscosity, turbidity, color, odor, or hardness falls within a predetermined range. Specifically, the dedicated water is, for example, purified water with a high purity. The dedicated water may also be an aqueous composition having a bactericidal effect, a disinfecting effect, an antibacterial effect, a deodorizing effect, or an antifungal effect.

[0503] Furthermore, the maintenance control unit 94 grasps the remaining amount of liquid in the water quality adjustment tank 700 based on, for example, the sensing result of a water level sensor in the water quality adjustment tank 700. When the remaining amount is less than a preset amount, the maintenance control unit 94 displays an instruction on the first instruction unit 91 and the second instruction unit 92 to supply liquid of a preset concentration or a medicine (tablets or concentrated liquid) to the water quality adjustment tank 700.

[0504] Furthermore, the maintenance control unit 94, for example, provides a sensor for detecting the remaining amount of the medicine in the cartridge of the medicine tank 50B, and grasps the remaining amount of the medicine in the cartridge by the sensor. When the remaining amount becomes low, the maintenance control unit 94 displays an instruction to replace the cartridge on the first instruction unit 91 and the second instruction unit 92.

[0505] The maintenance control unit 94 judges whether the water refilled into the water storage tank 46 is proper (genuine). Specifically, for example, the maintenance control unit 94 judges whether the refilled water is proper based on the item "sensing result" of the filter sensing data 933. For example, when the dedicated water is purified water, the predetermined value detected by the sensor units 61 and 62 is different from the value detected when the dedicated water is tap water.

[0506] The maintenance unit 9 stores in advance in the memory unit 93 the sensing results detected when the dedicated water is replenished with a predetermined range. When the water is replenished, the maintenance control unit 94 controls, for example, the water discharge unit 20 to discharge flush water from the faucet 12. The maintenance control unit 94 determines whether the sensing results detected at this time fall within a preset range.

[0507] If the detected sensing result does not fall within a preset range, the maintenance control unit 94 notifies the person who refills the water that the refilled water is not appropriate. If the detected sensing result does not fall within a preset range, the maintenance control unit 94 notifies the person who refills the water that some of the functions that are performed when the dedicated water is refilled will not be performed. If the detected sensing result does not fall within a preset range, the maintenance control unit 94 transmits, for example, to the communication unit 100B, an instruction to transition from a first mode in which the normal functions of the hand-washing device 1B are performed to a second mode in which some of the functions are restricted. The preset range of the sensing result may be updated to the latest value when the program is updated.

[0508] In this way, by determining whether the refilled water is genuine based on the properties of the water, the hand-washing device 1B is able to automatically determine whether the water is special water or not.

[0509] Furthermore, the maintenance control unit 94 may determine whether the refilled water is proper, for example, by reading predetermined information from a cartridge used when refilling the dedicated water. For example, when refilling the dedicated water from the dedicated water cartridge, the dedicated water cartridge and the hand-washing device 1B are physically connected. At that time, an electrical signal is transmitted from the dedicated water cartridge to the hand-washing device 1B. Upon receiving the signal, the hand-washing device 1B determines that proper dedicated water has been refilled.

[0510] In addition, a communication device that communicates non-contact (such as near-field wireless communication) between the hand-washing device 1B and the dedicated water cartridge may be provided. When the dedicated water cartridge approaches the hand-washing device 1B, the hand-washing device 1B reads information from the device provided in the dedicated water cartridge. When the read information satisfies a predetermined condition, the hand-washing device 1B determines that the regular dedicated water has been refilled.

[0511] Alternatively, a predetermined optical mark may be attached to the dedicated water cartridge, and the hand-washing device 1B may read the optical mark. If the read information satisfies a predetermined condition, the hand-washing device 1B determines that the genuine dedicated water has been refilled.

[0512] In this way, by determining whether the refilled water is genuine based on the information assigned to the container for transporting the special water, the hand-washing device 1B is able to determine whether the water is special water or not without performing any special additional processing.

[0513] The communication unit 100B is a unit that communicates with the information processing device 200B. The communication unit 100B includes a communication section 110 and a communication control section 120, similar to the communication unit 100 shown in FIG.

[0514] The communication unit 100B acquires first data related to hand washing and transmits it to the information processing device 200B. The communication unit 100B also acquires second data related to maintenance and transmits it to the information processing device 200B. The communication unit 100B also receives data transmitted from the information processing device 200B.

[0515] The communication control unit 120 is set, for example, so that there is a difference in operation between the first mode and the second mode. That is, the functions of the second mode are limited relative to the first mode. For example, the communication control unit 120 is set so as not to transmit, in the second mode, a portion of the data that was transmitted to the information processing device 200B in the first mode. In addition, for the hand-washing device 1B operating in the second mode, data accumulated in the information processing device 200B and analysis results based on the accumulated data may not be viewable. For example, the hand-washing device 1B operating in the second mode will not appear in a display showing how much each hand-washing device is being used, etc.

[0516] The information processing device 200B acquires the first data and the second data transmitted from the hand-washing device 1B and stores the acquired data. The information processing device 200B also acquires third data related to user information acquired via an application related to the hand-washing device 1B and stores the acquired data. The information processing device 200B transmits information requested by the hand-washing device 1B to the hand-washing device 1B. The information processing device 200B may be composed of multiple devices, each of which performs a specific function, and thus be recognized as a single information processing device. The hardware configuration of the information processing device 200B is the same as that of the information processing device 200 in FIG. 23, and therefore a description thereof will be omitted.

[0517] The terminal device 600 is a device carried by a user of the hand-washing device 1B. The terminal device 600 is an example of an item carried by the user, and is, for example, a communication device such as a smartphone or a smartwatch.

[0518] <Configuration of circulation unit 6B of hand washing device 1B> Figure 51 is a block diagram showing a circulation unit 6B of a hand-washing device 1B. As shown in Figure 51, the circulation unit 6B includes at least a water discharge unit 20, a drainage unit 30, and a purification unit 40B.

[0519] The purification unit 40B has a function of purifying the water supplied from the drainage unit 30 in the circulation unit 6B. The purification unit 40B has a water quality adjustment tank 700 and a water quality adjustment pump 701 in addition to the purification unit 40 described in the first embodiment.

[0520] The water quality adjustment tank 700 is a tank for storing a liquid for adjusting the property of the water circulated by the circulation unit 6B. When the property of the water circulated by the circulation unit 6B is acidic, the water quality adjustment tank 700 stores, for example, citric acid, tartaric acid, sodium acetate, glycolic acid, lactic acid, and ascorbic acid as an acid agent. The acid agent is generated, for example, by dissolving a tablet in the water supplied to the water quality adjustment tank 700 or by supplying a concentrated solution. When the property of the water circulated by the circulation unit 6B is alkaline, the water quality adjustment tank 700 stores, for example, ammonia water, ethanolamine, diethanolamine, triethanolamine, 2-amino-2-methyl, morpholine, and sodium hydroxide as an alkaline agent. The alkaline agent is generated, for example, by dissolving a tablet in the water supplied to the water quality adjustment tank 700 or by supplying a concentrated solution.

[0521] A water level sensor is disposed in the water quality adjustment tank 700. The water level sensor detects the water level of the liquid stored in the water quality adjustment tank 700. The water quality adjustment pump 701 is disposed at the rear of the water quality adjustment tank 700. The water quality adjustment pump 701 is operated under the control of the control unit 60, and adds liquid stored in the water quality adjustment tank 700 to the water that has been post-treated by the post-treatment filter 43.

[0522] Specifically, the control unit 60 operates the water quality adjustment pump 701 based on the liquid property detection result by, for example, a pH sensor arranged in the water storage tank 46. For example, when the value of the pH sensor reaches a first value, the control unit 60 operates the water quality adjustment pump 701 to add liquid until the value reaches a second value.

[0523] Water that has been post-treated by the post-treatment filter 43 and to which hypochlorous acid water and the liquid stored in the water quality adjustment tank 700 have been added flows into the water storage tank 46. The water storage tank 46 stores the flowing water. For example, a pH sensor is disposed in the water storage tank 46. The pH sensor detects the liquid property of the water stored in the water storage tank 46.

[0524] <Configuration of information processing device 200B> Fig. 52 is a block diagram showing the functional configuration of the information processing device 200B. As shown in Fig. 52, the information processing device 200B includes a communication unit 210, a control unit 220B, and a storage unit 230B.

[0525] The control unit 220B functions as a reception control unit 221, a transmission control unit 222, and a determination unit 229 as a result of the processor of the information processing device 200B carrying out processes according to a program.

[0526] The determination unit 229 determines a combination of medicines suitable for the user based on the collected data.

[0527] The storage unit 230B stores data and programs used by the information processing device 200B. The data used by the information processing device 200B is similar to the data used by the information processing device 200 of the third embodiment, for example.

[0528] The memory unit 230B stores product data DB231B, installation data DB232, aggregated data DB233B, hand-washing data DB234B, sterilization device usage data DB235, user data DB236B, maintenance DB237, environmental data DB238, monitoring data DB239, analysis results DB240, model DB241, water composition data DB243, and drug composition data DB244, etc.

[0529] The water composition data DB243 is a database for holding data relating to the composition of the water used in the hand-washing device 1B.

[0530] The drug composition data DB244 is a database for holding data relating to the composition of the drug used in the hand-washing device 1B.

[0531] The storage unit 230B may be a single storage device, or may be realized by a plurality of storage devices that store at least one database.

[0532] <Data Structure> Figures 53 to 58 are diagrams showing data structures of databases stored in information processing device 200B. Note that Figures 53 to 58 are merely examples, and do not exclude data that is not listed.

The item "fragrance" stores the fragrance attached to the medicine. The item "special information" stores special information about the medicine.

[0544] <Operation> <Special water certification> Next, the operation of the maintenance unit 9B in this embodiment will be described with reference to Figures 59 and 60. Figure 59 is a flowchart showing an example of the operation when the maintenance unit 9B certifies whether the refilled water is genuine or not.

[0545] First, dedicated water is refilled into water storage tank 46 of hand-washing device 1B. When water is refilled into water storage tank 46, maintenance control unit 94 detects the properties of the refilled water in step S171 using sensor units 61, 62. Specifically, for example, when water is refilled, maintenance control unit 94 controls water discharge unit 20 to discharge wash water from faucet 12. The maintenance control unit 94 detects the properties of the water circulated at this time using sensor units 61, 62.

[0546] In step S172, the maintenance control unit 94 determines whether the detected sensing result falls within a preset range. That is, the maintenance control unit 94 determines whether the refilled water is dedicated water. Specifically, the storage unit 93 pre-stores the sensing result detected when the dedicated water is refilled with a predetermined range. The maintenance control unit 94 determines whether the detected value falls within the pre-stored range. If the detected value falls within the pre-stored range (Yes in step S172), the maintenance control unit 94 operates the hand-washing device 1B in the first mode in step S173. On the other hand, if the detected value does not fall within the pre-stored range (No in step S172), the maintenance control unit 94 operates the hand-washing device 1B in the second mode in step S174.

[0547] FIG. 60 is a flowchart showing another example of the operation of the maintenance unit 9B when authenticating whether or not the replenished water is genuine.

[0548] In step S181, when water is refilled into water storage tank 46, maintenance control unit 94 reads information assigned to a container for carrying special water. Specifically, for example, hand-washing device 1B is provided with a reading device capable of reading information without contact. Also, the container is provided with a storage device that holds information in a format that can be read by the reading device. When water is refilled, maintenance control unit 94 reads information from the storage device attached to the container by the reading device.

[0549] In step S182, the maintenance control unit 94 determines whether the read information satisfies a predetermined condition. That is, the maintenance control unit 94 determines whether the refilled water is dedicated water. Specifically, the memory unit 93 pre-stores code information indicating that the water is dedicated water. The maintenance control unit 94 determines whether the read information matches the pre-stored code information.

[0550] <Medicine customization> Next, the operation of the hand-washing device 1B in this embodiment will be described with reference to Figure 61. Figure 61 is a flow chart showing an example of the operation of the hand-washing device 1B when customizing and discharging medicine.

[0551] First, a user who uses the hand-washing device 1B inserts, for example, a smartphone that is a user's personal item, into the UV sterilization device 80. In step S191, the communication control unit 120 acquires predetermined information from the smartphone. The predetermined information includes, for example, a user ID for identifying the user. The communication control unit 120 transmits the acquired user ID to the information processing device 200B.

[0552] In step S192, information processing device 200B determines the combination of medicine to be discharged based on the received user ID. Specifically, when control unit 220B receives the user ID, it reads hand-washing data DB234B, user data DB236B, or medicine composition data DB244 from storage unit 230B based on the received user ID. Control unit 220B determines the combination of medicine suitable for the user identified by the user ID based on the read hand-washing data DB234B, user data DB236B, or medicine composition data DB244. For example, control unit 220B determines the combination of medicine suitable for the user by taking into account the quality of past stains, medicines used in the past, etc. Control unit 220B transmits information regarding the combination of medicine to hand-washing device 1B.

[0553] In step S193, the hand-washing device 1B has the user wash their hands. Specifically, the hand-washing device 1B discharges wash water from the faucet 12 in response to the user's actions. The hand-washing device 1B also prepares a chemical agent with a determined mixture in response to the user's actions. After preparing the chemical agent, the hand-washing device 1B discharges the prepared chemical agent from the dispenser 14. The user wets their hands with the wash water discharged from the faucet 12, for example, and washes their hands with the chemical agent discharged from the dispenser 14. The user then rinses their chemically-contaminated hands with the wash water discharged from the faucet 12.

[0554] In step S194, communication control unit 120 transmits the data acquired by hand washing to information processing device 200B.

[0555] In step S195, control unit 220B updates the database stored in storage unit 230B based on the received data.

[0556] As described above, in this embodiment, dedicated water that meets certain properties is used as the cleaning water, which makes it possible to reduce the components that precipitate in the water and reduce the frequency of replacing filters, etc.

[0557] Therefore, according to the hand washing device 1B of this embodiment, the maintenance burden can be reduced.

[0558] In this embodiment, the hand-washing device 1B has a means for detecting that the dedicated water is being used. At this time, the hand-washing device 1B uses the sensor units 61 and 62 as a means for detecting that the dedicated water is being used. Also, the hand-washing device 1B uses a device for reading out predetermined information from a container for carrying the dedicated water as a means for detecting that the dedicated water is being used. This allows the hand-washing device 1B to detect that the dedicated water has been refilled without performing any special additional processing.

[0559] In this embodiment, the hand-washing device 1B is also configured to determine whether the refilled water is dedicated water or not based on the detection result by the detection means. This allows the hand-washing device 1B to automatically determine whether dedicated water has been refilled. This makes it possible to create an environment in which dedicated water can be used without any burden.

[0560] In this embodiment, when the hand-washing device 1B determines that the refilled water is dedicated water, it operates in a first mode, and when the refilled water is determined to not be dedicated water, it operates in a second mode with more limited functionality than the first mode. When water other than the recommended dedicated water is refilled, there is a possibility that the accuracy of the sensing results transmitted from the hand-washing device 1B to the information processing device 200B may vary. This may affect the accuracy of data analysis in the information processing device 200B. By restricting the uploading of data from the hand-washing device 1B that has not been refilled with dedicated water, it is possible to maintain the accuracy of data analysis in the information processing device 200B.

[0561] Furthermore, for the hand-washing device 1B operating in the second mode, data analysis based on the hand-washing data cannot be performed, and therefore the hand-washing device 1B operating in the second mode cannot receive feedback based on hand-washing at its own device. Furthermore, the hand-washing device 1B operating in the second mode is no longer subject to analysis performed by the information processing device 200B. Therefore, the hand-washing device 1B is no longer included in an overall display showing, for example, how much each hand-washing device is being used. In other words, unless the hand-washing device 1B is operated using dedicated water, the original functions of the hand-washing device 1B cannot be achieved. This can be an incentive to operate the hand-washing device 1B using dedicated water.

[0562] In this embodiment, circulation unit 6B also has water quality adjustment tank 700 for adding chemicals to adjust the quality of the water stored in water storage tank 46, and water quality adjustment pump 701. This makes it possible to adjust the quality of the wash water to a quality suitable for hand washing. Since hand washing device 1B is installed in various locations, the dirt to be washed may differ depending on the location. If it becomes possible to adjust the quality of the wash water for each hand washing device 1B, it becomes possible to appropriately wash hand dirt specific to the location where the hand washing device is installed, improving hygiene.

[0563] 61, an example has been described in which the communication control unit 120 acquires a user ID from the terminal device 600 carried by the user and transmits the acquired user ID to the information processing device 200B. However, the user ID may be transmitted from the terminal device 600 to the information processing device 200B.

[0564] Specifically, for example, when a user uses the hand-washing device 1B, the user operates the terminal device 600 to launch an application related to the hand-washing device 1B. The user transmits, via the application, to the information processing device 200B, a message indicating that the user is about to use the hand-washing device 1B together with the user ID. The information processing device 200B determines the combination of medicines to be ejected based on the received user ID.

[0565] The application related to the hand-washing device 1B may be a dedicated application for the hand-washing device 1B, or may be an application for a store, facility, etc. in which the hand-washing device 1B is installed. If the application related to the hand-washing device 1B is an application for a store, facility, etc., a user who washes his / her hands using the hand-washing device 1B may be provided with information useful for activities within the store or facility via this application.

[0566] Also, in Fig. 61, a case has been described in which the combination of medicines is determined by information processing device 200B based on information transmitted from hand-washing device 1B. However, hand-washing device 1B may determine the combination of medicines based on a designation input by a user. For example, when the combination of medicines is designated by the user, hand-washing device 1B ejects medicine prepared with the designated combination in step S193.

[0567] <Modification> Next, a hand-washing device 1B according to a modified example will be described. In this modified example, the hand-washing device 1B has a function of providing a user with a chemical agent that has an additional effect after washing their hands.

[0568] <Configuration of circulation unit 6B of hand washing device 1B> Figure 62 is a block diagram showing a circulation unit 6B of a hand-washing device 1B according to a modified example of embodiment 5. As shown in Figure 62, the circulation unit 6B includes at least a water discharge unit 20B, a drainage unit 30, and a purification unit 40B.

[0569] The water discharge unit 20B has a function of discharging the water purified by the purification unit 40B from the water discharge port 13 of the faucet 12 in the circulation unit 6B.

[0570] The water discharge unit 20B mainly includes a water discharge pump 21, a UV sterilization section 22, an infrared sensor 23, an additional agent tank 702, and a delivery pump 703.

[0571] The additional drug tank 702 is a tank for storing a drug that is expected to have a predetermined additional effect on hands after washing. The additional drug tank 702 has, for example, a plurality of cartridges each filled with a drug containing a predetermined component. The predetermined component is, for example, hyaluronic acid with a moisturizing effect, squalane with a moisturizing effect, lavender oil with a relaxing effect, peppermint oil with a bactericidal effect, or a fragrance for adding a scent. The additional drug tank 702 has a function of compounding the drug filled in the cartridge with the specified compounding when it receives a specification regarding the compounding of the drug.

[0572] The delivery pump 703 is disposed downstream of the additional chemical tank 702. The delivery pump 703 is operated under the control of the control unit 60, and adds the chemical prepared in the additional chemical tank 702 to the water after UV sterilization.

[0573] Specifically, when an object is detected by infrared sensor 23 under a condition that satisfies a predetermined condition, control unit 60 operates delivery pump 703 and discharge pump 21. For example, assume that an infrared sensor different from infrared sensor 23 is installed in hand-washing device 1B. When infrared sensor 23 detects an object within a predetermined period after this infrared sensor detects the object, control unit 60 operates delivery pump 703 and discharge pump 21.

[0574] In addition, for example, if an object is detected by the infrared sensor 23 after the hand-washing time displayed by the hand-washing indicator 15 has ended without the user changing, the control unit 60 may operate the delivery pump 703 and the water discharge pump 21.

[0575] <Configuration of information processing device 200B> Fig. 63 is a block diagram showing a functional configuration of an information processing device 200B according to a modified example. As shown in Fig. 63, the information processing device 200B includes a communication unit 210, a control unit 220B, and a storage unit 230B. The memory unit 230B stores product data DB231B, installation data DB232, aggregated data DB233B, hand-washing data DB234B, sterilization device usage data DB235, user data DB236B, maintenance DB237, environmental data DB238, monitoring data DB239, analysis results DB240, model DB241, water composition data DB243, drug composition data DB244, and additional drug composition data DB245, etc.

[0576] The additional agent composition data DB245 is a database for holding data relating to the composition of agents having additional effects that are used in the hand-washing device 1B.

[0577] <Data Structure> 64 to 68 are diagrams showing data structures of a database stored in an information processing device 200B according to a modified example. Note that Figs. 64 to 68 are merely examples and do not exclude data that is not shown.

[0578] Fig. 64 is a diagram showing an example of the data structure of product data DB231B. As shown in Fig. 64, each record of product data DB231B includes an item "product ID", an item "tank capacity", an item "weight", an item "model ID", an item "UV sterilization device", an item "chemical used", an item "added chemical", an item "chlorine type", an item "filter used", etc. Each item other than the item "added chemical" is the same as the item shown in Fig. 53.

[0579] The item "additional agent" stores the type of agent with additional effect that is provided in the hand-washing device 1B. In this embodiment, the additional agent tank 702 stores multiple types of agents, and therefore stores multiple agents for each product.

[0580] Fig. 65 is a diagram showing an example of the data structure of the aggregated data DB 233B. As shown in Fig. 65, each record of the aggregated data DB 233B includes an item "Product ID", an item "Date", an item "Number of times of hand washing", an item "Amount of dirt", an item "Component of dirt", an item "Amount of drug", an item "Amount of added drug", an item "Usage data", etc. Each item other than the item "Amount of added drug" is the same as the items shown in Fig. 54.

[0581] The item "additional drug amount" stores the amount of a drug with an additional effect used during a predetermined period (e.g., one day) for which data is collected. In this embodiment, the additional drug tank 702 stores a plurality of types of drugs, and therefore stores the amount of each drug used.

[0582] Fig. 66 is a diagram showing an example of the data structure of hand-washing data DB234B. As shown in Fig. 66, each record of hand-washing data DB234B includes an item "product ID", an item "date and time of use", an item "user ID", an item "time of use", an item "amount of use", an item "amount of purified water", an item "quality of purified water", etc. The item "amount of use" indicates the amount of substance used in one hand-washing. The item "amount of use" includes sub-items such as an item "amount of water", an item "amount of drug", an item "amount of added drug", and an item "amount of energy". Each item other than the sub-item "amount of added drug" is the same as the items shown in Fig. 55.

[0583] The item "amount of added medicine" stores the amount of medicine with added effect used in one hand washing. In this embodiment, the added medicine tank 702 stores multiple types of medicine, so the amount used for each medicine is stored.

[0584] FIG. 67 is a diagram showing an example of a data structure of the user data DB236B. As shown in FIG. 67, each record of the user data DB236B includes an item "location information", an item "use date and time", an item "product ID", an item "gender", an item "generation", an item "hand-washing evaluation", an item "hand-washing satisfaction", an item "user ID", an item "used drug", an item "additional drug", an item "whether or not smartphone sterilization is performed", an item "preferred fragrance", an item "desired effect", an item "skin condition", an item "allergy", an item "medication information", and the like. In the user data DB236B shown in FIG. 67, the item "additional drug", the item "fragrance preference", the item "desired effect", the item "skin condition", the item "allergy", and the item "medication information" are added to the user data DB236B shown in FIG. 56.

[0585] The item "additional drug" stores the type of drug with additional effect used by the user. The item "fragrance preference" stores information about the user's favorite fragrance.

[0586] The item "desired effect" stores information about the additional effect desired by the user. The items "Favorite Fragrance" and "Desired Effect" are examples of items that represent the user's preferences. The items that represent the user's preferences are not limited to "Favorite Fragrance" and "Desired Effect" and may be other items. For example, the items that represent the user's preferences may be a favorite brand, etc.

[0587] The item "skin condition" stores information regarding the user's skin condition.

[0588] The item "allergies" stores information about allergies the user has.

[0589] The item "medication information" stores information about the medication the user is taking. The items "skin condition", "allergies", and "medication information" are examples of items that represent the user's condition. Items that represent the user's condition are not limited to these, and may be other items. For example, items that represent the user's condition may be lack of sleep, whether or not the user is injured, whether or not the user smokes, etc.

[0590] Fig. 68 is a diagram showing an example of the data structure of the additional drug composition data DB 245. As shown in Fig. 68, each record of the additional drug composition data DB 245 includes an item "drug ID", an item "ingredients", an item "effect", an item "special information", and the like. The item "medicine ID" stores identification information (ID) of a medicine. The item "ingredients" stores information about ingredients of a drug. The item "effect" stores information regarding the effect of a drug. The item "special information" stores special information about the medicine.

[0591] <Operation> <Customization of additional drugs> Next, the operation of the hand-washing device 1B in this embodiment will be described with reference to Fig. 69. Fig. 69 is a diagram for explaining an example of the operation of the hand-washing device 1B and the information processing device 200B when the hand-washing device 1B customizes and ejects the added medicine.

[0592] The communication control unit 120 acquires predetermined information from the user's carried item, for example, by the same process as step S191 shown in Fig. 61. The predetermined information is, for example, a user ID for identifying the user. The communication control unit 120 transmits the acquired user ID to the information processing device 200B.

[0593] In step S1101, the information processing device 200B determines the combination of the medicine to be ejected and the additional medicine based on the received user ID. Specifically, when the control unit 220B receives the user ID, it reads out the hand-washing data DB234B, the user data DB236B, the medicine composition data DB244, or the additional medicine composition data DB245 from the storage unit 230B based on the received user ID. The control unit 220B determines the combination of medicine suitable for the user identified by the user ID based on the read hand-washing data DB234B, the user data DB236B, or the medicine composition data DB244.

[0594] Furthermore, the control unit 220B determines the blend of additional drugs suitable for the user identified by the user ID based on the read hand-washing data DB234B, user data DB236B, drug composition data DB244, or additional drug composition data DB245. For example, the control unit 220B determines the blend of drugs suitable for the user by taking into consideration the user's preferences, the user's condition, and additional drugs used in the past. The user's preferences include, for example, the user's favorite fragrance and the user's desired effect. The user's condition includes the user's skin condition, allergies the user has, the user's medication information, and the like. The control unit 220B transmits information regarding the blend of drugs and information regarding the blend of additional drugs to the hand-washing device 1B.

[0595] In step S1102, the hand-washing device 1B has the user wash their hands. Specifically, the hand-washing device 1B discharges wash water from the faucet 12 in response to the user's actions. The hand-washing device 1B also mixes a chemical agent with a determined mixture in response to the user's actions. After mixing the chemical agent, the hand-washing device 1B discharges the compounded chemical agent from the dispenser 14. The user wets their hands with the wash water discharged from the faucet 12, for example, and washes their hands with the chemical agent discharged from the dispenser 14. The user then rinses their chemically-contaminated hands with the wash water discharged from the faucet 12.

[0596] Hand-washing device 1B prepares the additional agent in a determined combination in response to the user's actions after washing their hands. After preparing the additional agent, hand-washing device 1B operates discharge pump 21 to discharge water from water storage tank 46 through faucet 12. Hand-washing device 1B operates delivery pump 703 in conjunction with discharge pump 21 to add the additional agent to the wash water discharged from faucet 12. The user applies the wash liquid with the added additional agent to their hands to enjoy the additional effect.

[0597] In step S1103, communication control unit 120 transmits data acquired by hand washing to information processing device 200B.

[0598] In step S1104, control unit 220B updates the database stored in storage unit 230B based on the received data.

[0599] As described above, in the modification of the fifth embodiment, the hand-washing device 1B has a delivery means (additional agent tank 702, delivery pump 703) for delivering an agent with an additional effect. This enables the hand-washing device 1B to provide the user with an agent with an additional effect in addition to washing their hands.

[0600] In this modified example, the hand-washing device 1B adds an agent with an additional effect to the washing water discharged from the faucet 12 and provides it to the user. This allows the user to use the agent with an additional effect as a continuation of hand-washing.

[0601] In addition, in this modified example, the additional effect is due to at least one of the moisturizing ingredients, aromatic ingredients, and medicinal ingredients contained in the medicine. This allows the user to pay attention to skin care after washing their hands. Furthermore, if the hand-washing device 1B is installed in a store, the aromatic ingredients can be scented with a scent specific to the store, or a scent recommended by the store. By applying a scent specific to the store or a scent recommended by the store to the hands after washing the hands, it becomes possible to enjoy the scent of the hands when entering the store. Furthermore, the scent remaining on the hands of a user who has entered the store also has an advertising effect on others.

[0602] In this modification, the additional agent tank 702 has a function of compounding an agent in a specified combination, which enables the hand-washing device 1B to provide an agent having any additional effect.

[0603] In addition, in this modification, the drug combination is determined based on information about the user. The information about the user is information about the user's condition or information about the user's preferences. This allows the user to enjoy the desired additional effect. Furthermore, the user is automatically provided with a drug with an additional effect that is suitable for the user.

[0604] In addition, in Figure 69, an example has been described in which the communication control unit 120 acquires specific information from the terminal device 600 carried by the user and transmits the acquired information to the information processing device 200B, but the specific information may also be transmitted from the terminal device 600 to the information processing device 200B.

[0605] FIG. 70 is a diagram for explaining an example of the operation of the hand-washing device 1B, the terminal device 600, and the information processing device 200B when predetermined information is transmitted from the terminal device 600 to the information processing device 200B.

[0606] For example, in step S1111, the user operates terminal device 600 to log in to a user page in which the user has registered for a provided service. Specifically, when using hand-washing device 1B, the user launches an application associated with the service. The user inputs a password or the like from a login screen of the launched application and logs in to the page. The service is provided, for example, by hand-washing device 1B, a store in which hand-washing device 1B is installed, or a facility in which a store is located.

[0607] Fig. 71 is a schematic diagram showing an example of a user page displayed on the display 610 of the terminal device 600. On the user page shown in Fig. 71, a field object 611 and operation objects 612 to 617 are displayed. The field object 611 is an object that represents, for example, an outline of a service. The operation objects 612 to 617 are objects for receiving instructions from the user. When the operation object 612 to 617 is selected by the user, the terminal device 600 transitions the display on the display 610 to a screen corresponding to the operation object 612 to 617.

[0608] The operation object 615 is an object to be selected when using the hand-washing device 1 B. When the user selects the operation object 615, the terminal device 600 transitions the display on the display 610 to a screen related to the use of the hand-washing device 1 B.

[0609] 72 and 73 are schematic diagrams showing examples of screens related to the use of the hand-washing device 1B. In the screens shown in Figs. 72 and 73, for example, a screen for inputting the user's preferences or the user's condition is displayed. The user selects, for example, one of the displayed options. After completing the selection, the user presses the operation object 618. The operation object 618 is an object for finalizing the selection and transmitting the selection to the information processing device 200B. When the operation object 618 is pressed by the user, the terminal device 600 transmits the user ID, information related to the user's preferences, or information related to the user's condition to the information processing device 200B.

[0610] In step S1112, information processing device 200B determines the combination of the medicine to be ejected and the additional medicine based on the received information. Specifically, when control unit 220B receives the user ID, it reads hand-washing data DB234B, user data DB236B, medicine composition data DB244, or additional medicine composition data DB245 from storage unit 230B based on the received user ID. Control unit 220B determines the combination of medicine suitable for the user identified by the user ID based on the read hand-washing data DB234B, user data DB236B, or medicine composition data DB244.

[0611] Furthermore, the control unit 220B determines the combination of additional drugs suitable for the user identified by the user ID based on the read hand-washing data DB234B, user data DB236B, drug composition data DB244, additional drug composition data DB245, or received information (information on the user's preferences and information on the user's condition). For example, the control unit 220B determines the combination of drugs suitable for the user by taking into consideration the received information and additional drugs used for past preferences and conditions. The control unit 220B transmits information on the combination of drugs and information on the combination of additional drugs to the hand-washing device 1B.

[0612] In step S1102, the hand-washing device 1B prompts the user to wash his or her hands, similar to the manner shown in FIG. In step S1103, the hand-washing device 1B transmits data acquired during hand-washing to the information processing device 200B. In step S1104, control unit 220B updates the database stored in storage unit 230B based on the received data.

[0613] In step S1113, the control unit 220B provides information useful for activities in the store or facility to the user who washed his / her hands using the hand-washing device 1B. The information useful for activities is, for example, information about various benefits such as coupons or points.

[0614] Fig. 74 is a schematic diagram showing an example of a screen displaying valid information provided by information processing device 200B. The screen shown in Fig. 74 displays that one store visit point has been awarded for washing hands with hand-washing device 1B. Note that the valid information is not limited to information provided from information processing device 200B, but may be provided from hand-washing device 1B through direct communication with hand-washing device 1B.

[0615] 69 and 70 have described a case where information acquired when washing hands is transmitted from hand washing device 1B to information processing device 200B in step S1103. In this embodiment, the user may input thoughts about hand washing, etc., to terminal device 600 as information acquired when washing hands. Terminal device 600 transmits information such as thoughts about hand washing to information processing device 200B as information acquired when washing hands. A predetermined incentive may be given by information processing device 200B to terminal device 600 that transmitted the thoughts, etc.

[0616] Also, in Figures 69 and 70, a case has been described in which the blending of the additional medicine is determined by information processing device 200B based on information about the user. In this embodiment, the determination of the blending of the additional medicine does not have to be based on information about the user. For example, control unit 220B may determine the blending of the additional medicine based on the environment in which hand-washing device 1B is installed. Specifically, for example, communication control unit 120 acquires environmental information such as atmospheric pressure, temperature, and humidity of the location in which hand-washing device 1B is installed at a predetermined period. Communication control unit 120 transmits the acquired environmental information and device ID to information processing device 200B.

[0617] When control unit 220B receives the device ID and the environmental information, it reads out hand-washing data DB234B, environmental data DB238, drug composition data DB244, or additional drug composition data DB245 from memory unit 230B based on the received device ID and environmental information. Control unit 220B determines a drug blend suitable for the current environment based on the read hand-washing data DB234B, environmental data DB238, drug composition data DB244, or additional drug composition data DB245.

[0618] In the modified example of this embodiment, the case has been described where the chemical stored in the additional chemical tank 702 is added to the flush water discharged from the faucet 12. In the modified example of this embodiment, the additional chemical may not be added to the flush water, but may be discharged from a different discharge port.

[0619] Fig. 75 is a block diagram showing another example of circulation unit 6B of hand-washing apparatus 1B according to a modified example of the fifth embodiment. Circulation unit 6B shown in Fig. 75 has, for example, additional drug tank 702, delivery pump 703, and infrared sensor 704. Control unit 60 causes additional drug tank 702 to mix a drug in response to detection of a hand by infrared sensor 704. The mixture of drugs is determined, for example, by information processing device 200B or hand-washing apparatus 1B as described above. After mixing the drug, control unit 60 operates delivery pump 703. Delivery pump 703 delivers the drug mixed in additional drug tank 702 to the discharge port.
