[0009] 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 repeated description thereof will be omitted.
[0010] First Embodiment <Summary> The hand-washing device 1 described in this embodiment can be installed in various locations, such as indoors and outdoors. Indoor locations include near the entrance to a building, the office space of a business occupying the building, and the entrance to a store. For example, if the building is a facility for accommodation, exercise, entertainment, or the like, and check-in is required to use the facility, the hand-washing device 1 is installed in the check-in area. For example, it is expected that users will wash their hands in the hand-washing device 1 before or after filling out certain information with a shared writing implement to check in.
[0011] <Overall structure> The overall configuration of the hand washing device 1 according to this embodiment will be described. Fig. 1 is a perspective view of the appearance 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 faucet 12, and a dispenser 14.
[0012] <Configuration of chassis 2> The housing 2 has a cylindrical shape. The housing 2 is formed by processing, for example, a drum. A top plate 10 is provided on the top of the housing 2. An installation hole penetrating the top plate 10 is formed in the center of the top plate 10.
[0013] 1B, an access hole 4 is formed on the outer peripheral surface of the housing 2, which provides access to the circulation unit 6 provided inside the housing 2. Note that the entire configuration of the circulation unit 6 does not have to be provided inside the housing 2, and at least a portion of the circulation unit 6 may be disposed outside the housing 2 as part of an external module 7.
[0014] A door 3 that can be opened and closed 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.
[0015] 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.
[0016] A drain port 17 is formed at the bottom of the hand-washing tub 11 to drain the wash water discharged into the tub. As shown in FIG. 1A, an overflow hole 18 is formed on the inner surface of the hand washing tub 11 to drain the washing water when the washing water in the tub exceeds a predetermined water level, thereby preventing the washing water from overflowing onto the top plate 10.
[0017] As shown in Figure 2, a water outlet 13 for discharging flush water is formed at the tip of the faucet 12. The faucet 12 is provided with an infrared sensor 23 (see Figure 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 as desired.
[0018] As shown in Figure 1B, the base of faucet 12 is attached to countertop 10. Faucet 12 extends upward from the base to the tip, and is curved in the middle so that spout 13 located at the tip faces downward.
[0019] In the following description, the direction from faucet 12 to hand-washing basin 11 in the 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. Furthermore, the left and right directions of a user who uses 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.
[0020] The faucet 12 is rotatable around the base. When the faucet 12 rotates around the base, the position of the spout 13 changes. That is, the water outlet 13 can be positioned above the hand-washing basin 11 as shown in Fig. 2, or above the outside of the housing 2 as shown in Fig. 4. Fig. 4 is an external view of the hand-washing device 1 with the position of the water outlet 13 changed.
[0021] 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 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.
[0022] As shown in FIGS. 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 (e.g., a detergent such as soapy water) for cleaning the skin, and a liquid or hand lotion with a bactericidal effect (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 fingers approaching hand washing tub 11. When an object is detected by the infrared sensor 52, the medicine is ejected from the nozzle tip of the dispenser 14.
[0023] 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 panel 10 of the housing 2. Hand-washing indicator 15 is arranged on the upper surface of top plate 10 outside hand-washing basin 11, and is formed on the upper edge of hand-washing basin 11 so as to surround hand-washing basin 11.
[0024] Hand-washing indicator 15 is configured, for example, by a plurality of LED lights. The plurality of LED lights are arranged, for example, on the upper edge of 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 therefor will be described later.
[0025] (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.
[0026] 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 external devices.
[0027] 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 a user. The memory is used to temporarily store programs and data to be processed by the programs, and is a volatile memory such as a DRAM (Dynamic Random Access Memory).
[0028] 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 an instruction set written in a program, and is composed of an arithmetic unit, registers, peripheral circuits, and the like.
[0029] 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 .
[0030] The water discharge unit 20 has the function of discharging the water purified by the purification unit 40 in the circulation unit 6 from the water outlet 13 of the faucet 12.
[0031] The water discharge unit 20 mainly includes a water discharge pump 21, a UV sterilization unit 22, and an infrared sensor 23.
[0032] The water discharge pump 21 is disposed downstream of the water storage tank 46 provided in the purification unit 40. The water discharge pump 21 is operated under the control of the control unit 60, and sends 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 the 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. When the infrared sensor 23 no longer detects an object, the control unit 60 stops the discharge pump 21.
[0033] The UV sterilization unit 22 is disposed between the discharge pump 21 and the faucet 12. The UV sterilization unit 22 sterilizes the water discharged from the discharge pump 21 by irradiating the water with ultraviolet light. The water that has passed through the UV sterilization unit 22 is discharged from the outlet 13 of the faucet 12 as cleaning 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.
[0034] Drainage unit 30 has the function of draining wash water discharged from faucet 12 toward hand-washing basin 11 in circulation unit 6.
[0035] 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 also prevents foreign matter that has entered through drain outlet 17 from reaching purification unit 40.
[0036] The drain pump 32 is disposed after the trap 35. The drain 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 drain pump 32 in response to the detection of water by the capacitance sensor 31. For example, the control unit 60 operates the drain pump 32 while water is detected by the capacitance sensor 31. When water is no longer detected by the capacitance sensor 31, the control unit 60 stops the drain pump 32.
[0037] 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 tub 11 and supplied via trap 35. Note that the sensor for detecting water supply is not limited to capacitance sensor 31. Water supply may be detected by referring to other sensing results.
[0038] 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.
[0039] The purification unit 40 has a function of purifying the water supplied from the drainage unit 30 in the circulation unit 6.
[0040] 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.
[0041] The pre-treatment filter 41 is disposed downstream of the drainage pump 32. The pre-treatment filter 41 performs pre-treatment on the water discharged from the drainage pump 32 to remove solids, 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 this is not limiting. For example, at least one of a thread-wound filter, a sediment filter, a microfiltration (MF) membrane, an ultrafiltration (UF) membrane, a nanofiltration (NF) 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 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.
[0042] 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.
[0043] 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 solenoid 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 water stored in the intermediate tank 44.
[0044] 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.
[0045] The reverse osmosis membrane 42 separates the water, which has been pressurized to a high pressure by the membrane filtration pump 47 and supplied thereto, into permeate from which dissolved components have been removed and concentrate from which the dissolved components have been concentrated. The reverse osmosis membrane 42 is realized, for example, by 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.
[0046] 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 normally open, and is configured to close the valve in response to a signal from the control unit 60.
[0047] The pressure regulating valve 73 regulates the flow rate or pressure of the concentrated water supplied to the intermediate tank 44 .
[0048] 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 normally closed, and opens in response to a signal from the control unit 60.
[0049] A sensor unit 61 is disposed upstream of the reverse osmosis membrane 42. In the illustrated example, the sensor unit 61 includes a pressure sensor, a flow rate sensor, and an EC / temperature sensor.
[0050] The pressure sensor detects the pressure of the water supplied to the reverse osmosis membrane 42 .
[0051] The flow rate sensor detects the flow rate of water supplied to the reverse osmosis membrane 42 .
[0052] 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 sensors, the sensor unit 61 may also 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
[0053] An air vent 71 is provided between the membrane filtration pump 47 and the sensor unit 61 to remove air from the water discharged from the membrane filtration pump 47 .
[0054] The post-treatment filter 43 is disposed downstream of 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 out by the reverse osmosis membrane. In this embodiment, an activated carbon filter is used as the post-treatment filter 43, but this is not limiting. For example, at least one of a thread-wound filter, a sediment filter, a microfiltration (MF) membrane, an ultrafiltration (UF) membrane, a nanofiltration (NF) 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 part of the external module 7.
[0055] A sensor unit 62 is disposed in the upstream stage 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.
[0056] The pressure sensor detects the pressure of the permeated water supplied to the post-treatment filter 43 .
[0057] The flow rate sensor detects the flow rate of the permeated water supplied to the post-treatment filter 43 .
[0058] The EC / temperature sensor detects the electrical conductivity and temperature of the permeated water supplied to the post-treatment filter 43. 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.
[0059] 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 through 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 inflowing concentrated water.
[0060] 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.
[0061] 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.
[0062] The purification unit 40 includes a chlorine tank 67 and a chlorine pump 68 . Chlorine tank 67 is a tank for storing hypochlorous acid water. Hypochlorous acid water is generated, for example, by dissolving hypochlorous acid tablets in water supplied to chlorine tank 67. Alternatively, hypochlorous acid water may be generated by dissolving salt in water supplied to chlorine tank 67 and electrolyzing the salt water. An electrolysis unit that electrolyzes saline to produce hypochlorous acid water may be separately provided downstream of the chlorine tank 67.
[0063] 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.
[0064] Inside the housing 2, a chemical tank 50 and a chemical pump 51 are provided.
[0065] Chemical pump 51 is disposed downstream of chemical tank 50. Chemical pump 51 is operated under the control of control unit 60, and delivers the chemical (such as soapy water) stored in chemical tank 50 to the nozzle of dispenser 14.
[0066] Specifically, control unit 60 operates chemical pump 51 in response to detection of an object by infrared sensor 52 of dispenser 14. For example, control unit 60 operates chemical pump 51 while an object is detected by infrared sensor 52. When an object is no longer detected by infrared sensor 52, control unit 60 stops chemical pump 51.
[0067] The chemical tank 50 is a tank for storing chemicals. A water level sensor is disposed in the chemical tank 50. The water level sensor detects the level of the chemical stored in the chemical tank 50. When the chemical level falls below a predetermined value, the chemical is replenished.
[0068] <External module 7 configuration> FIG. 3 is a front view of the external module 7 shown in FIG. As shown in FIG. 3, the external module 7 includes a pre-treatment filter 41, a post-treatment filter 43, and a UV sterilizer 80.
[0069] The pre-treatment filter 41 and the post-treatment filter 43 are arranged side by side outside the housing 2. More specifically, the pre-treatment filter 41 and the post-treatment filter 43 are arranged side by side horizontally outside the housing 2.
[0070] The mounting portion 82 of the pre-treatment filter 41 and the mounting 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 mounting portion 82 and the mounting portion 83. The pre-treatment filter 41 is detachably attached to the mounting portion 82. The post-treatment filter 43 is detachably attached to the mounting portion 83.
[0071] The pre-treatment filter 41 and the post-treatment filter 43 are stored in a container with permeability and the inside is visible. Therefore, the pre-treatment of water by the pre-treatment filter 41 and the post-treatment of water by the post-treatment filter 43 are visible from the outside. In the pre-treatment by the pre-treatment 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.
[0072] <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 surface of the carried items.

[0073] As shown in FIG. 1A, the UV sterilization device 80 is disposed on the side of the housing 2. UV sterilizer 80 has an insertion slot 81 that opens upward. A user inserts a smartphone through insertion slot 81. Here, UV sterilizer 80 may open in other directions, such as to the side, in addition to opening upward as shown in the figure.
[0074] When a smartphone is inserted through insertion port 81 and placed on a base (not shown) inside UV sterilizer 80, UV sterilizer 80 lowers the base and pulls the smartphone into the inside of UV sterilizer 80. A lid (not shown) is closed when the base is lowered to a predetermined position inside UV sterilization device 80. When the lid is closed, UV sterilization device 80 turns on the ultraviolet light source (lamp).
[0075] In this case, the light source may irradiate ultraviolet light in a direction toward a predetermined area of the smartphone that is likely to be particularly dirty, such as the vicinity of the home button or the center area of the display. The predetermined area may be statistically determined based on typical smartphone operation examples.
[0076] The predetermined position may also be set based on the operation log of the smartphone that is inserted. In this way, by concentrating ultraviolet light on particularly dirty areas, it is possible to shorten the time required for sterilization.
[0077] For example, the hand-washing device 1 may communicate with a user's personal item (for example, a device with a communication function such as a smartphone) to obtain information about the personal item or information about the user.
[0078] 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, a high-speed wireless communication standard, etc.), before the user sterilizes the smartphone with the UV sterilization device 80 in the hand-washing device 1, the user first places the smartphone in a predetermined position on the hand-washing device 1. This causes the smartphone to send predetermined information to the hand-washing device 1.
[0079] Here, the specified information may include information about the smartphone model, information about the attributes of the smartphone user (for example, an employee code if the user is an employee, etc., an age group of the user if the user is a general consumer, membership number information if the user is registered for a service provided by a store, etc., information used when processing payments (user identification information for the payment application, credit card information, etc.), and an operation log of the user's smartphone operations (coordinates of touches on the touch screen, application operation history, etc.).In this way, the user may be able to set the range of information provided from the smartphone to the hand-washing device 1).
[0080] Furthermore, (2) the hand-washing device 1 is assumed to be managed by an external server or the like and to be 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 may be read by the user's smartphone, and the smartphone may communicate information containing the identification information of the hand-washing device 1 with the external server or the like, so that the external server or the like may transmit information such as the model of the smartphone to the hand-washing device 1.
[0081] Also, (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 screen of the smartphone and have the hand-washing device 1 read it.
[0082] 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 ultraviolet light irradiated onto the smartphone by the UV sterilization device 80 based on information about the smartphone model. For example, the hand-washing device 1 may prioritize ultraviolet light irradiation over other areas, such as the location of the home button on the smartphone (the size and location 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 holds the smartphone vertically (the area frequently touched by the user's fingers when holding the smartphone vertically), and the areas near the left and right sides of the screen when the user holds the smartphone horizontally. For example, if the time for sterilization by the UV sterilization device 80 (time for ultraviolet light irradiation) is set to a fixed time period linked to the time spent washing hands, the hand-washing device 1 may determine the area to be preferentially irradiated by the UV sterilization device 80 within the fixed time period as described above.
[0083] The hand-washing device 1 may also determine the hand-washing time and the sterilization time using the UV sterilizer 80 based on user attribute information. For example, when a related person, such as an employee of a facility where the hand-washing device 1 is installed, uses the hand-washing device 1, the hand-washing device 1 may read the related person's information and set the hand-washing time and the sterilization time using the UV sterilizer 80 according to the related person's attributes. Some users, such as those in occupations that are expected to involve frequent contact with others, may be particularly required to wash their hands and sterilize their personal belongings. Accordingly, the hand-washing device 1 transmits a log of the times when employees washed their hands and sterilized their personal belongings using the hand-washing device 1 to an external server or the like. If the external server or the like manages access to the facility, access control may be based on the user's history of washing their hands using the hand-washing device 1. For example, there may be rooms where a user can enter even if they have not washed their hands using the hand-washing device 1, and there may be rooms where a user cannot enter if they have not washed their hands. This allows the facility manager to restrict access based on the user's history of washing their hands using the hand-washing device 1.
[0084] The UV sterilization device 80 turns on the UV light for a preset period of time and then turns off the UV light, which corresponds to, for example, the generally recommended time for hand washing. When the UV light is turned off, the UV sterilizer 80 opens the cover and raises the base to a predetermined position. The predetermined position refers to a position where part of the smartphone protrudes from the insertion slot 81 so that it can be touched by the user. This allows the user to insert and remove the smartphone without touching the UV sterilizer 80 while sterilizing the smartphone. The hand-washing device 1 may be configured to discharge water from the water outlet 13 in response to the user placing a personal item in the UV sterilization device 80. This may prevent the user from forgetting to sterilize the personal item with the UV sterilization device 80.
[0085] A sterilization indicator 16 (second indicator) is arranged on the top 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.
[0086] Sterilization indicator 16 is arranged in a portion of top plate 10 that is located between hand-washing basin 11 and UV sterilization device 80 when viewed from above. The sterilization indicator 16 is, for example, a circular indicator light when viewed from above. The sterilization indicator 16 is configured by an LED light. The lighting mode and control process of the sterilization indicator 16 will be described later.
[0087] <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.
[0088] (Water discharge processing 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).
[0089] The control unit 60 determines whether an object has been detected by the infrared sensor 23 (step S12). When using the hand washing device 1, the user places their hand in the hand washing basin 11 and causes the infrared sensor 23, which is located at the tip of the faucet 12, to detect their fingers.
[0090] In response to the detection of a finger by the infrared sensor 23 (YES in step S12), the control unit 60 operates the water discharge pump 21 (step S13). The water 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 water discharge pump 21 by irradiating it with ultraviolet light. The water that has passed through the UV sterilization unit 22 is discharged from the outlet 13 of the faucet 12 as flushing water. On the other hand, if the infrared sensor 23 does not detect a finger in step S12 (NO in step S12), the water discharge pump 21 does not operate (step S11).
[0091] The control unit 60 determines whether 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 have the medicine dispensed by the dispenser 14, the user moves their fingers away from the infrared sensor 23 located at the tip of the faucet 12. In response to the infrared sensor 23 not detecting a finger (NO in step S14), the control unit 60 stops the water discharge pump 21 (step S11).
[0092] On the other hand, in step S14, if the infrared sensor 23 does not detect a finger (YES in step S14), the control unit 60 continues to operate the water discharge pump 21 (step S13). The water discharge unit 20 repeats these processes to discharge flush water from the faucet 12. Control unit 60 may measure the time that infrared sensor 23 detects fingers, and may stop the discharge of water if the presence of fingers has been detected for a certain period of time. Furthermore, control unit 60 may stop the discharge of water in response to the completion of sterilization by UV sterilization device 80 while the water is being discharged.
[0093] (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).
[0094] 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).
[0095] In step S23, the drain pump 32 sends out the 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 there. The pressure sensor 33 detects the pressure of the water sent to the pre-treatment filter 41. The flow rate sensor 34 detects the flow rate of the water that has been pre-treated in the pre-treatment filter 41.
[0096] 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).
[0097] The drainage unit 30 repeats these processes and supplies the water discharged from the drain outlet 17 of the hand-washing tub 11 to the pre-treatment filter 41.
[0098] (Control process of the 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).
[0099] 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.
[0100] On the other hand, if the drainage pump 32 is not operating (NO in step S32), the control unit 60 keeps the membrane filtration pump 47 not operating (step S31).
[0101] 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 two-way electromagnetic valve 75 is closed, so the concentrated water does not flow into the drain tank 45.
[0102] The permeated water is subjected to post-treatment in the post-treatment filter 43. Then, hypochlorous acid water is added to the permeated water that has been post-treated in the post-treatment filter 43, and the permeated water flows into the water storage tank .
[0103] 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).
[0104] On the other hand, in step S34, if the electrical conductivity detected by the EC / temperature sensor is equal to or greater than the predetermined value (NO in step S34), the control unit 60 turns on the two-way solenoid valves 74 and 75 (step S36), thereby closing the two-way solenoid valve 74 and opening the two-way solenoid valve 75.
[0105] By closing two-way solenoid valve 74 and opening two-way solenoid valve 75, the concentrated water separated by reverse osmosis membrane 42 flows into drain tank 45 via two-way solenoid valve 75. That is, control unit 60 determines the amount of impurities in the concentrated water based on changes in electrical conductivity detected by the EC / temperature sensor. Concentrated water determined to contain a large amount of impurities is discharged into drain tank 45.
[0106] When the water level of the concentrated water stored in drainage tank 45 reaches a predetermined value, an alert is issued, for example, to the manager of hand-washing device 1. Upon confirming the alert, the manager discards the water stored in drainage tank 45.
[0107] 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 way, by opening the two-way solenoid valve 74 and closing the two-way solenoid valve 75, the concentrated water separated by the reverse osmosis membrane 42 flows into the intermediate tank 44 via the two-way solenoid valve 74. Then, the control unit 60 stops the membrane filtration pump 47 (step S31).
[0108] In step S35, if 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).
[0109] The purification unit 40 repeats these processes to purify the water drained by the drainage unit 30 and store it in the water storage tank 46.
[0110] (Process for removing water from the water tank 46) Next, the process of removing 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 transporting the hand-washing device 1, the water in the water storage tank 46 is removed to reduce the weight of the hand-washing device 1, making the transport easier. Furthermore, regardless of whether or not transportation work is performed, work to remove the water from the water storage tank 46 is also performed when the hand washing device 1 is stored for a long period of time, when the hand washing device 1 is closed, and the like.
[0111] The hand washing device 1 can be switched between a first state for the user to wash their hands and a second state for removing water from the water storage tank 46. In the first state, the water outlet 13 of the faucet 12 is positioned 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.
[0112] Specifically, with the water outlet 13 of the faucet 12 positioned above and outside the housing 2, the administrator 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.
[0113] The manager continues to detect the presence 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 outlet 13.
[0114] Furthermore, 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 upward and outside the housing 2. When the hand-washing device 1 is in the first state, the hand-washing device 1 may transition from the first state to the second state in response to the movement of the water outlet 13 of the faucet 12 upward and outside the housing 2. Also, for example, the administrator inputs a predetermined command in the first state, which causes the water outlet 13 of the faucet 12 located above the hand-washing basin 11 to automatically move upward outside the housing 2.
[0115] Furthermore, the output of notifications such as errors 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 water storage tank 46 or the like does not have a certain amount of water so that the user can wash their hands from outlet 13 of faucet 12, an error may be notified by causing hand-washing indicator 15 to emit a predetermined light, etc., while when hand-washing device 1 is in the second state, no error may be notified even if the remaining amount in water storage tank 46 or the like falls below a certain amount.
[0116] Furthermore, the manner in which water is discharged from the water outlet 13 of the faucet 12 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, once a certain time has passed since water was discharged from the water outlet 13, the water discharge may be stopped even if the infrared sensor 23 detects the user's fingers (the time for discharging water for hand washing may be within a certain time), but when the hand-washing device 1 is in the second state, the water discharge from the water outlet 13 may not be stopped regardless of the passage of time.
[0117] <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 illustrating the display mode of hand-washing indicator 15. Fig. 8 is an explanatory diagram showing the control process of hand-washing indicator 15.
[0118] 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 their hand below dispenser 14, infrared sensor 52 of dispenser 14 detects the hand. When infrared sensor 52 detects the hand, control unit 60 operates chemical pump 51 to eject chemical from dispenser 14. If dispenser 14 is operating (YES in step S42), control unit 60 turns on hand-washing indicator 15 (steps S43 to S44).
[0119] Specifically, the control unit 60 turns on the 30 LED lights that make up the hand-washing indicator 15 in clockwise order, starting from the LED light located near the base of the faucet 12 in a top view, as shown in Fig. 7A. At this time, the control unit 60 turns on all the LED lights in, for example, about 1 to 2 seconds.
[0120] Then, as shown in Fig. 7B, once all of the LED lights are turned on (step S44), the control unit 60 maintains the 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 with 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 turns off all the LED lights in, for example, about 30 to 40 seconds.
[0121] Hand-washing device 1 may detect the user's fingers with infrared sensor 23 and turn off hand-washing indicator 15 sequentially over time as described above in response to the discharge of water from water outlet 13. This allows the lighting state of hand-washing indicator 15 to change as water is discharged from water outlet 13, making it possible for the user to recognize the time from the discharge of water to the completion of hand-washing. In addition, if the hand washing device 1 does not detect the user's 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).
[0122] Then, as shown in FIG. 7D, when all the LED lights are turned off (step S45), the state returns to the initial state (step S41). The time it takes for the hand-washing indicators 15 to light up and turn 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 provide the user with a rough guide for the hand-washing time required to achieve a sufficient washing effect.
[0123] <Display mode of sterilization indicator 16 and control process> Next, a description will be given of the display mode and control process of hand-washing indicator 15. Fig. 9 is a diagram illustrating the display mode of hand-washing indicator 15. Fig. 10 is an explanatory diagram showing the control process of hand-washing indicator 15.
[0124] As shown in Figure 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 off (NO in step S52 in Figure 10).
[0125] Then, as shown in Fig. 9A, when a portable item (smartphone) is inserted into insertion slot 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.
[0126] As time passes after the LED light starts flashing, control unit 60 shortens the flashing cycle of the LED light (step S54). The sterilization process in UV sterilizer 80 corresponds to the control of sterilization indicator 16. In other words, control unit 60 speeds up the flashing as the sterilization process in UV sterilizer 80 progresses.
[0127] When the sterilization process in UV sterilizer 80 is finished, as shown in Figure 9D, control unit 60 lights up the LED light in a color different from the previous flashing 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 sterilizer 80 opens the cover and raises the carried item to a position where the user can take it out.
[0128] 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 slot 81 (NO in step S56), the control unit 60 keeps the LED light on (step S55). By keeping the LED light on in this way, it is possible to prevent the user from forgetting to remove the carried item from the insertion slot 81.
[0129] The processing time of the sterilization process by UV sterilization device 80 may be the same as or equivalent to the lighting time of hand-washing indicator 15. In this way, the time for which the user washes their hands can be associated with the time for the sterilization process by UV sterilization device 80. This prevents users who have just washed their hands from having to wait extra for the UV sterilization process to finish.
[0130] 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 outside the hand washing device 1.
[0131] That is, for example, there is no need to attach a hose to the tip of the faucet 12 or remove the water storage tank 46, which has a certain weight, from inside the housing 2. This makes it possible to easily remove flush water from the water storage tank 46 and reduces the difficulty of moving it.
[0132] 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.
[0133] Furthermore, when a drum can is used as the housing 2, it is possible to ensure design while keeping manufacturing costs down.
[0134] Alternatively, the housing 2 may be transported by rolling it by placing the exercise portion on the ground. In this case, to facilitate rolling the housing 2 on the ground, devices such as the pre-treatment filter 41, post-treatment filter 43, and UV sterilizer 80 installed outside the housing 2 may be detachable from the housing 2, as shown in FIG. 1B. This makes it easier for staff of the business installing the housing 2 (e.g., office staff of a business company, store staff, etc.) to relocate the housing 2 themselves, without requiring specialized transportation staff to move the housing 2. For example, the housing 2 may be installed near the entrance of a store to have customers wash their hands with the hand-washing device 1 before entering. In this case, depending on the location of the housing 2, it may be 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 example described above, store management staff can search for a good location to install the housing 2 in order to provide customers with an environment where they can wash their hands.
[0135] 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 on hand washing device 1, such as disposing of concentrated water with many impurities stored in drainage tank 45 or replacing reverse osmosis membrane 42.
[0136] 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.
[0137] Furthermore, the hand-washing device 1 is equipped with a hand-washing indicator 15, which suggests an appropriate hand-washing time to the user, thereby providing a high level of cleaning effect when using the hand-washing device 1. Furthermore, use of the hand-washing device 1 can educate users about the appropriate hand-washing time.
[0138] Furthermore, since the hand washing indicator 15 is arranged on the top surface of the housing 2, outside the hand washing basin 11, the visibility of the hand washing indicator 15 to a user washing their hands using the hand washing basin 11 can be ensured.
[0139] In addition, hand-washing indicator 15 is formed on the upper edge of hand-washing tub 11 so as to surround hand-washing tub 11. Therefore, when hand-washing indicator 15 is lit, it can exhibit excellent design.
[0140] Furthermore, the post-processing filter 43 is disposed outside the housing 2 and is housed in a container whose interior is visible. This allows the user to visually check from the outside the state of the permeated water filtered by the post-processing filter 43.
[0141] 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 function of purifying the wash water by the circulation unit 6.
[0142] The pre-treatment filter 41 is also placed outside the housing 2 and stored in a container whose interior can be seen. This allows the user to visually compare the wastewater flowing into the pre-treatment filter 41 with the purified water flowing out of the post-treatment filter 43. This provides a more effective sense of security to the user.
[0143] The circulation unit 6 also includes an intermediate tank 44, a drainage tank 45, a water storage tank 46, a water discharge unit 20, and a drainage unit 30. This allows the intermediate water generated during the flushing process to be appropriately separated and stored.
[0144] Furthermore, because the hand-washing device 1 is equipped with a UV sterilization device 80, users can sterilize their personal items while washing their hands. Generally, personal items such as smartphones, which are carried around all the time and operated with the hands, have a high rate of bacterial adhesion to their surfaces, making habitual sterilization treatment necessary for hygiene reasons. Sterilizing the surface of a smartphone with a UV sterilization device 80 can solve this problem.
[0145] Furthermore, the UV sterilization device 80 is disposed on the side of the housing 2. This makes it easier for a user who uses the hand-washing device 1 to wash their hands to insert a portable item into the UV sterilization device 80.
[0146] Furthermore, UV sterilization device 80 is arranged as part of external module 7 that is attached to the outside of housing 2. This improves the appearance of housing 2. Furthermore, separate installation work for attaching only UV sterilization device 80 to housing 2 is not required.
[0147] Furthermore, the hand-washing device 1 is provided with a sterilization indicator 16. This allows the progress of the sterilization process to be presented to the user, thereby ensuring user convenience.
[0148] Furthermore, sterilization indicator 16 is disposed on the upper surface of housing 2, outside hand-washing basin 11. This ensures that sterilization indicator 16 is easily visible to the user.
[0149] In addition, sterilization indicator 16 is disposed between hand-washing tub 11 and external module 7. This allows a user who has washed their hands in hand-washing tub 11 to easily check the progress of the sterilization process displayed by sterilization indicator 16 while checking the status of UV sterilization device 80. This further ensures user convenience.
[0150] In addition, a step of operating the membrane filtration pump 47 is executed when the drainage pump 32 is operating. Therefore, membrane filtration processing using the reverse osmosis membrane 42 can be performed according to the amount of wastewater generated. This makes it possible to balance the flow rate of circulating water throughout the entire circulation system, even though the capacity of each tank is limited. Also, it becomes possible to carry out the purification processing efficiently.
[0151] In addition, the pre-processing filter 41 and the post-processing filter 43 are stored in visible containers and disposed outside the housing 2. When the membrane filtration pump 47 operates while the drainage pump 32 is operating, the user can simultaneously check from outside how the drainage pump 32 is operating, causing the drainage water to flow into the pre-treatment filter 41, and how the membrane filtration pump 47 is operating, causing the permeated water to flow into the post-treatment filter 43.
[0152] 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.
[0153] <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.
[0154] In this modified example, 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.
[0155] 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 the drainage process and the cleaning process, and executes the water discharge process, which is a step of discharging water from the faucet 12 to remove water stored in the water storage tank 46.
[0156] 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. This makes it even easier to remove the flush water in the water storage tank 46 by automatically controlling the orientation of the faucet 12.
[0157] <Other variations> 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 this is not limited to this. 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 include the sterilization indicator 16.
[0158] 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 oval or the like. This makes it easy to move the housing 2 by rolling it with your hand, while preventing it from rolling too far even when you let go of it.
[0159] In the above embodiment, an example was described in which one infrared sensor is arranged at the water outlet 13, but this is not limited to this. Four infrared sensors may be arranged in a cross shape at the water outlet 13. This makes it possible to determine in which direction a user who has discharged wash water from the water outlet 13 at the start of hand washing moves their hands after wetting them. If it is possible to determine the user's behavior after wetting their hands, it becomes possible to determine whether the user has properly used the disinfectant.
[0160] In this way, the hand-washing device 1 may 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 at 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 at a certain location tends to be appropriate.
[0161] 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.
[0162] 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 interior is visible, but the present invention is not limited to this.
[0163] 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.
[0164] The shape, structure, display mode, and control process of the hand-washing indicator 15 can be changed as desired. Also, the hand-washing device 1 does not necessarily have to include the hand-washing indicator 15.
[0165] The shape, structure, display mode, and control process of the sterilization indicator 16 can be changed as desired. The sterilization indicator 16 may be provided in the UV sterilization device 80. Furthermore, the hand-washing device 1 does not necessarily have to be provided with the sterilization indicator 16.
[0166] 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.
[0167] <Second embodiment> A hand washing device according to the second embodiment will be described. In the second embodiment, maintenance of a hand washing device with a water circulation function will be described. Note that 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 on which maintenance work can be performed.
[0168] <Overall structure> The following describes 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.
[0169] 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 also includes a housing 2, a hand washing tub 11 provided in part of the housing, a faucet 12 for discharging wash water, a dispenser 14, and the like, as in the first embodiment, to enable hand washing.
[0170] The configurations of the circulation unit 6, the chemical tank 50, and the UV sterilization device 80 are the same as those in the first embodiment, and therefore will not be described repeatedly.
[0171] Maintenance unit 9 is configured to control 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.
[0172] <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 instruction unit 91, a second instruction unit 92, a storage unit 93, and a maintenance control unit 94.
[0173] 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 notify 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, which will be described later.
[0174] The first indicator 91 is configured, for example, 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 indicator 91 may also be installed, for example, on the outside of the hand-washing basin 11 on the top surface of the housing 2, and may be, for example, the sterilization indicator 16 of the first embodiment. In other words, the first indicator 91 is not limited to the above example, as long as it is an indicator installed in a position visible to a user washing their hands. For example, the first indicator 91 may be installed in a position near the user, on the outside of the hand-washing basin 11 on the top surface of the housing 2.
[0175] First indicator 91 is composed of a light-emitting element and can be illuminated in multiple illumination modes. First indicator 91 changes the illumination mode based on the need for maintenance and outputs first instruction information. The illumination mode here includes illumination color, illumination brightness, and whether or not to flash. For example, first indicator 91 outputs the first instruction information by illuminating blue when no maintenance of the hand washing device is required, illuminating yellow when the maintenance due date will arrive in a predetermined period, illuminating red when the maintenance due date will arrive soon, and flashing red when operation has stopped because maintenance was not performed.
[0176] Furthermore, first instruction unit 91 operates when the user is washing their hands. For example, first instruction unit 91 is hand-washing indicator 15, which displays an estimate of the hand-washing time while the user is washing their hands, and changes the lighting state based on the need for maintenance to output first instruction information.
[0177] First instruction unit 91 notifies the user of the need for maintenance of the hand-washing device, allowing the user to understand the maintenance status and 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, thereby urging the manager to perform the maintenance work appropriately.
[0178] The second instruction unit 92 is installed inside the housing and outputs second instruction information to notify the user of the maintenance items that require maintenance. The maintenance items here refer to the maintenance of the components that the hand washing device includes and that require maintenance work.
[0179] 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 included in the circulation unit 6 Refilling chemical tank 50 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
[0180] The second instruction indicates the type of maintenance required, for example, that a medication needs to be refilled.
[0181] Second indicator 92 may be configured so that it is not visible to a general user washing their hands during normal use. For example, second indicator 92 is a display device that is installed inside housing 2 and can be seen by the person in charge of the hand washing device when they open door 3, and displays the identification number of the maintenance item that requires maintenance.
[0182] The second indicator 92 is configured with a predetermined display device that can identify and display the maintenance content. For example, the second indicator 92 is configured with a 7-segment LED. The second indicator 92 identifies and displays the maintenance content by combining the lighting of seven LEDs.
[0183] The second instruction unit 92 may also be configured as a display device that displays an optical mark indicating the maintenance content. The optical mark is a mark that encodes the maintenance content, such as a barcode, a one-dimensional pixel code, or a two-dimensional pixel code. More specifically, for example, the second instruction unit 92 displays a QR code (registered trademark) corresponding to the maintenance of the hand-washing device. The manager of the hand-washing device reads the QR code with a terminal device carried by the manager. The terminal device displays on a display the maintenance items that require maintenance and the work procedures for performing the maintenance items.
[0184] 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 maintenance work appropriately.
[0185] The storage unit 93 stores a program according to the second embodiment and data used by a maintenance control unit 94 (described later). The data used by the maintenance control unit 94 includes, for example, the following data.
[0186] (a) Parameters for driving the various hardware components of the hand washing device Pump drive parameters (1) Pump drive values (voltage, current), cumulative drive time, and pump maintenance records (2) Pump service life
[0187] Tank operation control parameters (1) Tank capacity, material, and service life (2) Fluctuations in tank capacity (3) Tank cumulative operating time and maintenance records
[0188] -Valve operation control parameters (1) Valve drive value (voltage, current), cumulative drive time, operating time / timing (2) Valve service life
[0189] (a) Sensing results -Sensing results of various sensors capable of sensing underwater (for example, the following items can be sensed by sensors) (1) Flow rate, pressure, water level, temperature (2) pH, electrical conductivity, oxidation-reduction potential, alkalinity, ion concentration, hardness (3) Turbidity, color, viscosity, dissolved oxygen (4) Odor, ammonia nitrogen, nitrate nitrogen, nitrite nitrogen, total nitrogen, residual chlorine, total phosphorus, total organic carbon, total inorganic carbon, total trihalomethanes (5) Detection results of microbial sensors, chemical oxygen demand, biological oxygen demand, (6) Cyanide, mercury, oil, surfactants (7) Optical sensor detection results, TDS (Total Dissolved Solids) sensor detection results (8) Mass spectrometry results, fine particles, zeta potential, surface potential
[0190] Image data (1) Hand-washing monitoring image data (2) Tank monitoring image data (3) Filter monitoring image data (4) Piping monitoring image data
[0191] (c) Other information Environmental information (1) Atmospheric pressure, temperature, and humidity (2) Information indicating the location of the environment (installation location)
[0192] User Data (1) User attributes (gender, nationality, place of residence, occupation) (2) User usage history (hand-washing time, frequency)
[0193] Controller Data (1) Manager attributes (gender, nationality, place of residence, industry) (2) Administrator's management history (maintenance history, consumables purchase history)
[0194] 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 amount sensing data 934, and sterilizer usage history data 935.
[0195] The hand-washing device usage history data 931 is a database of hand-washing device usage history, which will be described in detail later.
[0196] 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.
[0197] 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 that are provided in the circulation unit 6. Details will be described later.
[0198] The remaining liquid amount 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. Details will be described later.
[0199] Sterilization device usage history data 935 is a database of the usage history of UV sterilization device 80. Details will be described later.
[0200] 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 memory 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.
[0201] The data acquisition module 941 acquires, from the storage unit 93, data used to perform processing for controlling 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.
[0202] 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 the 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.
[0203] 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.
[0204] <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.
[0205] 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."
[0206] The item "Date and Time" stores the time information when the user is washing their hands using the hand washing device, including the date and time.
[0207] The item "Detailed Information" stores information about the operation of the hand washing device when washing hands, such as the water discharge, medicine discharge, and duration of water discharge of the hand washing device. 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.
[0208] 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 discharged, the number of times medicine has been discharged, and the number of times the user has washed their hands.
[0209] FIG. 14 is a diagram showing the data structure of the component management data 932.
[0210] As shown in FIG. 14, each record of the component management data 932 includes information such as the item "component identification information," the item "date and time of last maintenance," the item "usable number of hand washings," the item "number of hand washings since last maintenance," and the item "remaining number of hand washings."
[0211] The item "component identification information" is information for identifying the component corresponding to each maintenance item, and stores the name and identification number of the component. Note that it may also be the identification number alone.
[0212] The item "Last maintenance date and time" stores the date and time when the most recent maintenance was performed on the component corresponding to each maintenance item.
[0213] The "number of hand-washing times that can be used" item indicates the number of hand-washing times that can be used for the component corresponding to each maintenance item from immediately after maintenance is performed until the next maintenance period, and is information based on the attributes of each component. For example, if 50 hand-washings can be performed from immediately after replacing the pre-treatment filter until the next replacement is required, "50 times" is stored as the "number of hand-washings that can be used" for the pre-treatment filter. The "number of hand-washings that can be used" item may be preset for each component, or may be rewritten when the program for the hand-washing device is updated.
[0214] The item "Number of hand washings since last maintenance" is information regarding the number of hand washings performed since the last maintenance for the component 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 ejected 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.
[0215] The "remaining number of hand washes" item is information about the remaining number of hand washes that can be performed until the next maintenance period for the component corresponding to each maintenance item. The "remaining number of hand washes" item is a value obtained by subtracting the "number of hand washes since the last maintenance" item from the "usable number of hand washes" item. For example, if the pre-treatment filter can be used for 50 hand washes with one replacement and 30 hand washes have been performed since the last replacement, the "remaining number of hand washes" will be stored as "20."
[0216] 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 component's identification information is stored, for example, in a wireless tag. The maintenance control unit 94 reads out the identification information stored in the wireless tag using, for example, a reader function. The component's identification information may also be stored, for example, in a memory installed in the component. When the component is installed, the maintenance control unit 94 accesses the memory and reads out the stored identification information.
[0217] The maintenance control unit 94 adds the read identification information to a new record in the "component identification information" item of the component management data 932. At this time, the maintenance control unit 94 determines whether the read identification information complies with predetermined rules. The predetermined rules may be changed depending on the release date of the component. If the read identification information does not comply with the predetermined rules, the maintenance control unit 94 notifies the replacer that the replaced component is not appropriate.
[0218] 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.
[0219] FIG. 15 is a diagram showing the data structure of the filter sensing data 933. As shown in FIG.
[0220] 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," and an item "sensing result."
[0221] The "sensor identification information" item is information for identifying each sensor, and stores the name and identification number of the sensor. Note that it is also possible to store only the identification information. 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, pressure sensor 33, sensor unit 61, sensor unit 62, etc.
[0222] The item "date and time" stores the date and time when each sensor performed sensing.
[0223] The item "Sensing Results" is the detection results obtained by sensing with each sensor, and indicates the water pressure, flow rate, or electrical conductivity before or after the filter.
[0224] 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. Additionally, if the pressure or flow rate exceeds a predetermined value, it determines that the reverse osmosis membrane 42 is clogged and needs to be replaced.
[0225] The filter sensing data 933 allows the maintenance control unit 94 to, for example, determine the degree of wear of each filter and determine the need for replacement of each filter.
[0226] FIG. 16 is a diagram showing the data structure of the remaining liquid level sensing data 934. As shown in FIG.
[0227] 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."
[0228] The "component identification information" item is information for identifying the component that stores each liquid, and stores the component's name and identification number. Alternatively, only the identification information may be stored. The liquids include 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.
[0229] The item "Date and Time" stores the date and time when each sensor performed sensing. The sensor may be a water level sensor installed in each storage member to detect the remaining amount of liquid.
[0230] The item "Sensing result" is the detection result obtained by sensing with each sensor, and indicates the liquid level in each storage member.
[0231] The maintenance control unit 94 determines the remaining amount of each liquid based on the sensing results of each water level sensor, and determines whether replenishment or disposal is necessary. For example, if the sensing result of the water level sensor provided in the chemical tank falls below a predetermined value, it determines that chemical replenishment is necessary.
[0232] The liquid remaining amount sensing data 934 allows the maintenance control unit 94 to, for example, grasp the remaining amount of each liquid and grasp the need for refilling or discarding each liquid.
[0233] FIG. 17 is a diagram showing the data structure of the sterilizer usage history data 935.
[0234] As shown in FIG. 17, each record of the sterilization device usage history data 935 includes information such as the item "component identification information," the item "date and time," and the item "ultraviolet irradiation pattern."
[0235] The item "Component Identification Information" is information for identifying a sterilization device, and stores the name and identification number of the component. Note that it is also possible to store only the identification information. Examples of sterilization devices include UV sterilization devices 80.
[0236] The item "Date and Time" stores the time information when the UV sterilization device 80 is operating, including the date and time.
[0237] The item "ultraviolet ray irradiation pattern" is information indicating how UV sterilization device 80 irradiates ultraviolet rays. "Ultraviolet ray irradiation pattern" includes a pattern in which UV sterilization device 80 irradiates the entire surface of the user's belongings with ultraviolet rays, a pattern in which UV sterilization device 80 irradiates UV rays in a concentrated manner on a predetermined area, and an abnormal state in which UV rays cannot be irradiated. The maintenance control unit 94 obtains, for example, information related to the usage history from UV sterilization device 80.
[0238] The sterilizer usage history data 935 allows the maintenance control unit 94 to grasp, for example, the operating status of the sterilizer and to grasp any abnormal conditions of the sterilizer.
[0239] <Operation> The operation of controlling the first instruction unit and the second instruction unit by the maintenance unit will be described below. FIG. 18 is a diagram showing a flow of processing for controlling the first instruction unit 91 and the second instruction unit 92.
[0240] 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, 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 component management data 932.
[0241] 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.
[0242] 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-washings. Specifically, the maintenance control unit 94 determines the necessity of maintenance for each maintenance item based on the remaining number of hand-washings for each maintenance item, and further determines the necessity of maintenance for the hand-washing device.
[0243] For example, the maintenance control unit 94 extracts the minimum value from the remaining number of hand washings for each maintenance item. If the extracted minimum value is 15 or more, the maintenance control unit 94 determines that the need for maintenance of each maintenance item and hand washing device is "no maintenance required."
[0244] Furthermore, if the minimum value is less than 15 times or 5 times or more, the maintenance control unit 94 determines that the maintenance item corresponding to the minimum value and the need for maintenance of the hand washing device are "preparation for maintenance."
[0245] Furthermore, if the minimum value is less than 5 times or equal to or greater than 1 time, the maintenance control unit 94 determines that the maintenance item corresponding to the minimum value and the need for maintenance of the hand washing device are "maintenance required."
[0246] Furthermore, the maintenance control unit 94 stops the operation of the hand washing device if 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."
[0247] 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.
[0248] Specifically, if it is determined in step S183 that the necessity for maintenance of each maintenance item and the hand-washing device is "no maintenance required," maintenance control unit 94, for example, lights up first indicator 91 in blue and displays information indicating that maintenance is not required on second indicator 92. For example, second indicator 92 displays identification number "00," indicating that maintenance is not required.
[0249] Also, in step S183, if the maintenance item corresponding to the minimum value and the need for maintenance of the hand washing device are determined to be "maintenance preparation," the maintenance control unit 94, for example, lights up the first indicator 91 in yellow and displays the identification number of the maintenance item in the second indicator 92.
[0250] Furthermore, in step S183, if the maintenance item corresponding to the minimum value and the need for maintenance of the hand washing device are determined to be "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 the second indication unit 92.
[0251] Furthermore, in step S183, if it is determined that the maintenance item corresponding to the minimum value and the necessity of maintenance of the hand washing device are "not to be restarted unless maintenance is performed," the maintenance control unit 94 will, for example, cause the first indication unit 91 to flash in red and display the identification number of the maintenance item in question on the second indication unit 92.
[0252] The threshold values for the remaining number of times are not limited to the above-mentioned 15 and 5. The threshold values may be larger or smaller than these. In addition, although alerts are issued in stages such as "No maintenance required," "Preparing for maintenance," "Maintenance required," and "Do not restart unless maintenance is performed," the stages of alerts are not limited to these. The number of stages may be more or less than these.
[0253] Furthermore, when the minimum value reaches 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 reaches 0. For example, the hand washing device may be allowed to be used several times even after the minimum value reaches 0. If use continues without maintenance after the minimum value reaches 0, the maintenance control unit 94 more strongly urges maintenance to be performed.
[0254] 18 shows an example in which the first and second indicators are controlled based on the remaining number of hand-washing times, but this is not limiting. The first and second indicators may be controlled as follows. Note that any control process may be used, or multiple control processes may be used in combination.
[0255] (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 filter flow path 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.
[0256] 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, reverse osmosis membrane 42, 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 indicator 91 in red and displays the identification number corresponding to the reverse osmosis membrane 42 on the second indicator 92.
[0257] Furthermore, when a predetermined behavior, for example, a behavior indicating an abnormality in a filter, occurs in the sensing results 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 indicator 91 in red, and displays the identification number corresponding to the corresponding filter on the second indicator 92.
[0258] (a) Control based on remaining liquid amount A sensor for detecting the water level is provided in the container for storing the liquid to detect the remaining amount of liquid. The maintenance unit 9 controls the outputs of the first indicator 91 and the second indicator 92 based on the remaining amount of liquid.
[0259] For example, a water level sensor that detects the remaining amount of chemical is provided in chemical tank 50, and when the sensing result of the water level sensor falls below a predetermined value, maintenance control unit 94 determines that chemical needs to be replenished. Maintenance control unit 94 lights first indicator 91 in red and displays the identification number corresponding to chemical tank 50 on second indicator 92.
[0260] (c) Control based on abnormality detection results of sterilization equipment A detection means is provided to detect abnormalities that occur in the sterilization device. The maintenance unit 9 controls the outputs of the first indicator 91 and the second indicator 92 based on the abnormality detected in the sterilization device.
[0261] 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 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 indicator 91 in red and displays the identification number corresponding to the UV sterilization device 80 on the second indicator 92.
[0262] Furthermore, for example, the maintenance control unit 94 acquires the usage history of the UV sterilization unit 22 from the UV sterilization unit 22. When the UV sterilization unit 22 notifies the maintenance control unit 94 that an abnormality has occurred in the ultraviolet radiation, the maintenance control unit 94 determines that maintenance of the UV sterilization unit 22 is required. The maintenance control unit 94 lights up the first indicator 91 in red and displays the identification number corresponding to the UV sterilization unit 22 on the second indicator 92.
[0263] Through the above series of processes, maintenance unit 9 can appropriately provide information regarding the maintenance of the hand-washing device through first instruction unit 91 and second instruction unit 92. This allows the maintenance staff to appropriately and efficiently perform the maintenance of the hand-washing device.
[0264] Note that the detection of abnormality by the maintenance unit 9 is not limited to the above. When a predetermined behavior, for example, behavior indicating an abnormality in the water discharge unit 20, the drainage unit 30, or the purification unit 40, occurs in the sensing results 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 indicator 91 in red, and displays the identification number corresponding to the corresponding unit on the second indicator 92.
[0265] <Display example> Display examples of the first indicator 91 and the second indicator 92 will be described.
[0266] Fig. 19 is a diagram showing an example of the 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 the user is washing their hands, it displays an estimate of the hand-washing time and notifies the user of the need for maintenance of the hand-washing device in different lighting modes.
[0267] For example, when the hand-washing device does not require maintenance, the hand-washing indicator 15 lights up blue, and when the hand-washing device requires maintenance, the hand-washing indicator 15 lights up red. As shown in Figure 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 indicate the need for hand-washing device maintenance.
[0268] This allows the user to be notified of the need for hand washing device maintenance in a manner that is easy for the user to see while washing their hands. This allows the user to understand the maintenance status and sanitation status of the hand washing device. In addition, the need for maintenance can be notified to the hand washing device manager, which can encourage the manager to perform maintenance work appropriately.
[0269] Fig. 20 is a diagram showing an example of the 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 that requires maintenance by displaying the identification number of the maintenance item.
[0270] For example, as shown in Fig. 20, if it is determined that the pre-processing filter 41 needs to be replaced, the second indicator 92 displays the identification number "02" of the pre-processing filter 41. If there is no maintenance item that requires maintenance, the identification number "00" may be displayed. If a technical error occurs that cannot be resolved by replacement or the like, a preset identification number "88" may be displayed, for example.
[0271] This allows the manager of the hand washing device to be notified of specific maintenance items that require maintenance, allowing the manager to carry out maintenance work appropriately.
[0272] The maintenance control unit 94 may also determine whether a replaced component, such as a filter, is appropriate based on the "sensing result" item in the filter sensing data 933. For example, the flow rate characteristics of the pre-treatment filter 41, reverse osmosis membrane 42, and post-treatment filter 43 vary depending on the materials used. In other words, the pressure or flow rate detected before or after the filter varies depending on the materials used.
[0273] The maintenance unit 9 stores in advance in the memory 93 typical pressure values or flow rate values, etc., detected when the appropriate 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 flush water from the faucet 12. The maintenance control unit 94 determines whether the pressure value or flow rate value detected at this time falls within the preset pressure value or flow rate value range. If it does not fall within the range, the maintenance control unit 94 notifies the person replacing the replaced components that the replaced components are not appropriate. The preset pressure value or flow rate value, etc., may be updated to the latest value when the program is updated.
[0274] <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 will be assigned the same reference numerals and descriptions thereof will be omitted.
[0275] <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.
[0276] 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.
[0277] 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 is equipped with a communication unit 100. The communication unit 100 is configured to control communication with an information processing device 200.
[0278] 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 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, etc.
[0279] The monitoring device 300 is a device that monitors the area around the hand-washing device 1. The monitoring device 300 is installed in a position that allows it to monitor the area around the hand-washing device 1. For example, the monitoring device 300 may be a camera or the like 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 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 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 using a camera to capture images of the area around the hand-washing device 1, it is possible to determine based on the captured images whether the user is washing their hands properly (for example, whether they are performing each step of (1) wetting their hands, (2) applying chemicals to their skin, (3) massaging their hands, and (4) rinsing them off. Alternatively, as shown in the "Hand-washing Evaluation" section described below, an infrared sensor attached to the hand-washing device 1 can be used to evaluate how the user moves their hands when washing their hands), whether there is a malfunction (described below), or whether maintenance is required (for example, the hand-washing device 1 outputs an indication (e.g., emits light) that maintenance is required). Furthermore, by using a sensor such as a motion sensor to sense the area around the hand-washing device 1, 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 hand washing. In this case, the monitoring device 300 transmits the detected hand size to the hand washing 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 hand washing device 1, and the hand size may be detected by the hand washing device 1. Furthermore, instead of detecting the hand size directly, the hand size may be estimated from the user's attributes such as height, gender, and age.
[0280] The maintenance terminal 400 is a device owned by a person in charge of maintaining the hand-washing device 1. For example, the maintenance terminal 400 may be a mobile terminal such as a smartphone, tablet, or laptop PC, or a desktop 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 be configured to input setting data to the hand-washing device 1. The setting data may include, for example, reference data for detecting abnormalities in the circulation unit 6, the number of times a replaceable part can be used, a threshold value for determining the need for maintenance (e.g., the number of times a replaced part has been 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 (e.g., information assigned to genuine parts), a threshold value or reference value used to control the hand-washing device 1, such as the distance at which the infrared sensor detects that the user's fingers are separated, etc.
[0281] 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 may be recognized as a single information processing device by each of the multiple devices performing a function and processing.

[0285] The reception control module 121 controls the process of the communication unit 100 receiving signals 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.
[0286] The transmission control module 122 controls the process of the communication unit 100 transmitting a signal to an external device in accordance with a communication protocol. Specifically, the transmission control module 122 transmits first data related to hand washing or second data related to maintenance to the information processing device 200.
[0287] Data acquisition module 123 acquires data to be transmitted to information processing device 200 from memory unit 93. For example, data acquisition module 123 acquires hand-washing device usage history data 931, component management data 932, filter sensing data 933, remaining liquid level sensing data 934, or sterilizer usage history data 935 from memory unit 93. Data acquisition module 123 may aggregate the acquired data for each predetermined period to create aggregated data. The predetermined period may be, for example, one day or one week. The aggregated data may include, for example, the number of hand-washings performed during the predetermined period, the amount of chemicals used during the predetermined period, etc. Data acquisition module 123 also acquires monitoring data acquired by monitoring device 300 and stored in memory unit 93.
[0288] The input module 124 receives input of setting data from the maintenance terminal 400 .

That is, the control unit 60 dispenses a larger amount of drug for users with larger hands and a smaller amount of drug for users with smaller hands. In this case, the amount of drug is calculated based on, for example, the number of times drug pump 51 is operated and the amount of drug dispensed during hand washing.
[0352] The item "energy amount" stores the amount of energy used in one hand washing session. The amount of energy is, for example, the amount of electricity used in one hand washing session.

[0385] <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 the operation when the communication unit 100 transmits data to the information processing device 200.
[0386] 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, records that have not yet been transmitted to the information processing device 200 from the hand-washing device usage history data 931, component management data 932, filter sensing data 933, remaining liquid sensing data 934, or sterilizer 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. Furthermore, when a tendency for an abnormality to occur in the circulation unit 6 is detected, the communication control unit 120 reads out the record of the filter sensing data 933 at that time. When a tendency for an abnormality to occur in the circulation unit 6 is detected, for example, this refers to 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 predetermined time or a predetermined cycle. The timing for reading out the monitoring data may be less frequent than the timing for reading out data from the databases 931 to 935.
[0387] In step S112, the communication control unit 120 transmits the acquired records such as hand washing device usage history data 931, component management data 932, and filter sensing data 933, 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 such as component management data 932, filter sensing data 933, and remaining liquid amount sensing data 934 as second data to the information processing device 200.
[0388] This enables the hand washing device 1 to transmit data related to hand washing (first data), such as the number of times hand washing is performed per day, the amount of water used in hand washing, the amount of detergent used in hand washing, the time taken to wash hands, information related to dirt, the time when hand washing was performed, and location information when hand washing was performed, to the information processing device 200. In addition, the hand washing device 1 can transmit data related to maintenance (second data), such as the date and time of maintenance, sensing results required for maintenance, items to be replaced, and failure data, to the information processing device 200.
[0389] <Data collection by information processing device 200> Next, the data collection process by the information processing device 200 in this embodiment will be described with reference to Fig. 35. Fig. 35 is a flowchart showing an example of the operation of the information processing device 200 when collecting data.
[0390] 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.
[0391] The reception control unit 221 also receives third data input from a user's personal item (a communication device such as a smartphone or 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 user inserts the personal item into the UV sterilization device 80. 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 personal 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.
[0392] 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.
[0393] <Monitoring Data Analysis of Information Processing Device 200> Next, the monitoring data analysis process performed by the information processing device 200 in this embodiment will be described with reference to Fig. 36.

[0394] In step S131, the analysis unit 223 analyzes at least one of the image data and sensor data acquired from the monitoring device 300 to acquire the user who used the hand washing device 1, the usage time, the location of the malfunction, etc. Specifically, when the analysis unit 223 receives image data from the communication unit 100, it 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 user's gender, generation (age), time spent washing their hands, etc. Furthermore, the analysis unit 223 performs image analysis on the image data received from the communication unit 100 to detect faults or failures in the hand-washing device 1 due to dirt, external damage, etc. Furthermore, the analysis unit 223 performs image analysis on the image data received from the communication unit 100 to detect the situation around the hand-washing device 1, such as the number of people, etc. 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 failure, calculates the time the hand-washing device 1 has been used, and so on.
[0395] In step S132, the control unit 220 stores the data acquired by the analysis in a target database stored in the storage unit 230.
[0396] <Analysis processing> Next, the analysis process performed 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 performed by the information processing device 200 when analyzing data.
[0397] 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 according to the purpose of analysis from the data stored in each database, and shapes the extracted data into a form suitable for the desired analysis.
[0398] 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.
[0399] In step S142, the analysis unit 223 performs an analysis of hand washing based on the formatted data. Specifically, for example, based on the shaped data, the analysis unit 223 acquires, for each of a plurality of areas, the change over time in the number of times the hand-washing device 1 is used. 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 obtained by analysis unit 223 to the operator of information processing device 200. By referring to the comparison results for each area of the change in the number of times of use over time, the operator of information processing device 200 can understand the demographic trends between areas. 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.
[0400] Next, we will explain the case where the purpose of analysis is (i) to understand the prevalence of hand-washing habits. 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.
[0401] In step S142, the analysis unit 223 acquires, for example, based on the shaped data, the change over time in the number of times the 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. The analysis unit 223 arranges the data so that the expansion / contraction of areas with high usage counts and 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 understand the prevalence of hand washing habits by referring to the enlargement / reduction of areas with high usage counts and areas with a large number of users who have given high ratings for hand washing.
[0402] Next, for example, a case where the purpose of analysis is (d) understanding user trends 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.
[0403] In step S142, the analysis unit 223 acquires the hand-washing characteristics for each classified cluster based on the shaped data, for example, and compares the hand-washing characteristics for each cluster.
[0404] In step S143, the output unit 225 presents the comparison results acquired by the analysis unit 223 to the operator of the information processing device 200. The operator of the information processing device 200 can understand the tendencies of users of the hand-washing device 1 by referring to the hand-washing characteristics of each cluster.
[0405] The analysis unit 223 may analyze the data using a trained analysis model.
[0406] <Estimation process> Next, the estimation process performed 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 performed by the information processing device 200 when estimating a predetermined event.
[0407] First, for example, a case where the purpose of analysis is (c) to understand the state of various filters in the hand washing device 1 will be described. In step S141, the shaping unit 224 extracts data according to the purpose of analysis 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 the various filters based on the shaped data. Specifically, for example, the analysis unit 223 acquires past sensing results that are 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 understand the state of various filters by referring to the wear tendency of the filters.
[0408] Next, a case where the purpose of analysis is (e) to determine the location 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 it in chronological order. In step S152, the analysis unit 223 acquires past sensing results that are similar to the behavior of the current sensing result, for example, based on the formatted data. The analysis unit 223 refers to the acquired past sensing results and past maintenance data to estimate parts that may be at risk of failure. In step S153, the output unit 225 presents the parts where a failure is likely to occur, estimated by the analysis unit 223, to the operator of the information processing device 200. By referring to the parts where a failure is likely to occur, the operator of the information processing device 200 can grasp in advance where a failure will occur.
[0409] Next, for example, a case where the purpose of analysis is (f) to identify the optimum 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 it in chronological order. In step S152, the analysis unit 223 acquires, for example, based on the shaped data, the change over time in the number of times the hand washing device 1 is used, the increase or decrease in the number of times the hand washing device 1 in the surrounding area is used after the installation of a specific hand washing device 1, etc. The analysis unit 223 compares the acquired trend with the current situation and estimates areas (locations) where the number of hand washings is expected 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 understand the optimal installation location by referring to the presented area.
[0410] Next, we will explain the case where the purpose of analysis is (g) formulating optimal sanitation policies. 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 previously issued by a predetermined local government, the dates on which the hygiene policies were issued, and index values representing the sanitary environment. The shaping unit 224 selects necessary data from the extracted data and rearranges it in chronological order. In step S152, the analysis unit 223 obtains a predetermined correlation, for example, based on the formatted data, by comparing changes over time in index values, 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 that is appropriate 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.
[0411] 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 that uses a predetermined trend as input data and trains a result highly related to the trend as correct output data.
[0412] <Analysis model learning> Next, the analytical model learning process performed 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 performed by the information processing device 200 when training an analytical model.
[0413] In step S161, the learning unit 226 acquires data according to the analysis purpose of the analytical model from each database.
[0414] In step S162, the learning unit 226 learns the 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. <Analysis of users in the space where hand-washing device 1 is installed> (c) The information processing device 200 may output analysis results of user tendencies for unspecified users who use the space in which the hand-washing device 1 is installed, based on information about users who wash their hands using the hand-washing device 1. For example, the information processing device 200 analyzes the trends of users who use the hand-washing device 1 (e.g., age group, gender, etc.) based on the user data DB 236, the installation data DB 232, etc., and outputs the trends of users in the space where the hand-washing device 1 is installed as the analysis result. For example, even in a space where check-in operations for facility use are not accepted from users, the hand-washing device 1 can be installed in a store or the like within the facility, and users can use the hand-washing device 1 to analyze the trends of users who visit the store or the like. The store or the like can accumulate data for analyzing the trends of users who visit the store or the like through hand-washing with the hand-washing device 1 before users who visit the store or the like finalize their purchases, 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 users' queues 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 the user urging the user to wash their hands using the hand-washing device 1. Through the above processing, the information processing device 200 may update the user data DB 236.
[0415] (i) The information processing device 200 may be placed in a space where the hand-washing device 1 is installed, and may analyze a preferable position for placing the hand-washing device 1. For example, 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 have washed their hands using hand-washing device 1, based on footage from a surveillance camera installed in the space and the history of hand-washing using hand-washing device 1. Depending on the comparison result (e.g., if the number of times hand-washing device 1 has been used is low compared to the number of users), information processing device 200 may notify the user of information processing device 200 to move hand-washing device 1 to a location that is easier to use. As described above, the information processing device 200 may provide the analysis functions and analysis results to the business that installs the hand-washing device 1. Here, the analysis functions 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.
[0416] 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, thereby enabling efficient collection of data related to hand washing.
[0417] Furthermore, a plurality of portable hand washing devices that can be installed anywhere may be installed in the information processing system, which allows for more efficient collection of hand washing-related data.
[0418] 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, allowing data collection. By configuring it in this manner, data related to hand washing can be collected more efficiently.
