Further, (3) When the hand-washing device 1 has a reading unit (optical scanner or the like) for reading a two-dimensional code (including information on the smartphone model) displayed on the smartphone or the like, the user can display the screen on the smartphone. The two-dimensional code may be displayed and read by the hand-washing device 1.

As described above, an example of wireless communication between the hand-washing device 1 and the smartphone 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 in which the UV sterilizer 80 irradiates the smartphone with ultraviolet rays based on the information of the smartphone model. For example, the position where the home button is placed on the smartphone (the size of the smartphone and the position of the home button are specified by the smartphone model), and the position from the bottom to the center of the screen when the user operates the smartphone vertically. Areas to be used (the range in which the finger frequently touches when the user operates the smartphone vertically), and other areas corresponding to the left and right sides of the screen when the user operates the smartphone horizontally. It may be possible to irradiate the ultraviolet rays with priority in comparison with the area. For example, in the hand washing device 1, when the time for sterilizing by the UV sterilizing device 80 (ultraviolet irradiation time) is set to be within a certain time in conjunction with the hand washing time, the UV sterilizing device 80 gives priority to the time within the fixed time. The range to be irradiated may be determined as described above.

Further, the hand-washing device 1 may determine the hand-washing time and the sterilization time by the UV sterilizing device 80 based on the information of the user's attributes. For example, when a person concerned such as an employee of a facility where the hand-washing device 1 is installed uses the hand-washing device 1, the information of the person concerned is read by the hand-washing device 1 so that the hand-washing device 1 can be used for hand-washing according to the attributes of the person concerned. The time and the sterilization time by the UV sterilizer 80 may be set. Depending on the user, it may be necessary to wash hands and sterilize personal belongings, such as occupations that are expected to have many contacts with people. As a result, the hand-washing device 1 transmits a log of the time when the employee or the like washed the hands and sterilized the carried items with the hand-washing device 1 to an external server or the like. When the entrance / exit management of the facility is performed on the external server or the like, the entry / exit may be controlled based on the history of the user washing the hands with the hand washing device 1. For example, there may be a room where the user can enter the room even when the user has not washed his / her hands with the hand washing device 1, and there may be a room where he / she cannot enter the room when he / she has not washed his / her hands. As a result, the facility manager can regulate entry and exit based on the history of the user washing his / her hands with the hand washing device 1.

The UV sterilizer 80 turns off the UV light when the UV light is turned on for a preset period. The preset period corresponds, for example, to the generally recommended hand-washing time.
When the UV light is turned off, the UV sterilizer 80 opens the lid and raises the pedestal to a predetermined position. The predetermined position represents a position where a part of the smartphone protrudes from the insertion slot 81 so as to be contactable by the user.
This allows the user to insert and remove the smartphone while sterilizing the smartphone without touching the UV sterilizer 80.
The hand-washing device 1 may be discharged from the spout 13 in response to the fact that the carry-on item is installed in the UV sterilizer 80. This can prevent the user from forgetting to sterilize the belongings with the UV sterilizer 80.

A sterilization indicator 16 (second indicator) is arranged on the outer surface of the hand-washing tank 11 on the upper surface of the housing 2. The sterilization indicator 16 displays the progress of the sterilization process of the carried item by the UV sterilization device 80.

The sterilization indicator 16 is arranged in a portion of the top plate 10 located between the hand-washing tank 11 and the UV sterilization device 80 in the top view.
The sterilization indicator 16 is, for example, an indicator lamp having a circular shape when viewed from above. The sterilization indicator 16 is composed of an LED light. The lighting mode of the sterilization indicator 16 and the control process will be described later.

<Control process of hand washing device 1>
Next, the control process of the hand-washing device 1 will be described. FIG. 6 is an explanatory diagram showing a control process of the hand-washing device 1.

(Water discharge treatment of water discharge unit 20)
First, the water discharge treatment 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).

The control unit 60 determines whether or not an object has been detected by the infrared sensor 23 (step S12). When using the hand-washing device 1, the user reaches out to the hand-washing tank 11 and causes an infrared sensor 23 arranged at the tip of the faucet 12 to detect the finger.

The control unit 60 operates the water discharge pump 21 in response to the detection of the fingers by the infrared sensor 23 (YES in step S12) (step S13).
The water discharge pump 21 allows the water stored in the water storage tank 46 to pass through the UV sterilization unit 22. The UV sterilization unit 22 sterilizes the water sent from the water discharge pump 21 by irradiating the water with ultraviolet rays. The water that has passed through the UV sterilizing unit 22 is discharged from the spout 13 of the faucet 12 as washing water.
On the other hand, in step S12, when the finger is not detected by the infrared sensor 23 (NO in step S12), the water discharge pump 21 does not operate (step S11).

The control unit 60 determines whether or not an object has been detected by the infrared sensor 23 (step S14). When terminating the hand-washing device 1 or discharging the drug to the dispenser 14, the user separates the fingers from the infrared sensor 23 arranged at the tip of the faucet 12.
The control unit 60 stops the water discharge pump 21 in response to the non-detection of the finger by the infrared sensor 23 (NO in step S14) (step S11).

On the other hand, in step S14, when the infrared sensor 23 does not detect the finger (YES in step S14), the control unit 60 continuously operates the water discharge pump 21 (step S13).
The water discharge unit 20 repeats these processes and discharges wash water from the faucet 12.
The control unit 60 may stop the water discharge when the finger is detected for a certain period of time by measuring the time during which the finger is detected by the infrared sensor 23. Further, the control unit 60 may stop the water discharge in response to the completion of the sterilization by the UV sterilizer 80 while discharging the water.

(Wastewater treatment of drainage unit 30)
Next, the wastewater treatment in the wastewater unit 30 will be described.
As shown in FIG. 6, the drainage pump 32 is stopped when there is no drainage from the hand-washing tank 11 (step S21).
Then, when the washing water discharged from the faucet 12 toward the hand washing tank 11 is drained from the drain port 17 of the hand washing tank 11, the capacitance sensor 31 detects the drainage (step S22).

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, when 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).

In step S23, the drainage pump 32 sends the drainage to the pretreatment filter 41. The water pretreated by the pretreatment filter 41 flows into the intermediate tank 44 and is stored in the intermediate tank 44. The pressure sensor 33 detects the pressure of water sent to the pretreatment filter 41. The flow rate sensor 34 detects the flow rate of the water that has been pretreated by the pretreatment filter 41.

Then, after step S23, when the capacitance sensor 31 detects that the drainage flowing from the drainage port 17 has disappeared (NO in step S24), the control unit 60 stops the drainage pump 32 (step S21).
On the other hand, in step S24, when the capacitance sensor 31 detects that the drainage is continuously flowing from the drainage port 17 (YES in step S24), the control unit 60 continuously operates the drainage pump 32. (Step S23).

The drainage unit 30 repeats these treatments and supplies the water discharged from the drainage port 17 of the hand-washing tank 11 to the pretreatment filter 41.

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

The control unit 60 determines whether or not the drainage pump 32 is operating (step S32).
When 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.

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

In step S33, the water supplied to the reverse osmosis membrane 42 is separated into concentrated water and permeated water in 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 via the two-way solenoid valve 74. Since the two-way solenoid valve 75 is in a closed state, concentrated water does not flow into the drainage tank 45.

In the post-treatment filter 43, the permeated water is post-treated. Then, the permeated water that has been post-treated by the post-treatment filter 43 is added with hypochlorite water and flows into the water storage tank 46.

After step S33, the control unit 60 determines whether or not the electrical conductivity detected by the EC / temperature sensor of the sensor unit 61 arranged in front of the reverse osmosis membrane 42 is less than a predetermined value (step). S34).
When the electric conductivity detected by the EC / temperature sensor is less than a predetermined value (YES in S34), the control unit 60 determines whether or not the drainage pump 32 is operating (step S35). When the drainage pump 32 is operating (YES in step S35), the control unit 60 continuously operates the membrane filtration pump 47 (step S33).

On the other hand, in step S34, when the electric conductivity detected by the EC / temperature sensor becomes a predetermined value or more (NO in step S34), the control unit 60 has the two-way solenoid valve 74 and the two-way solenoid valve 75. Is turned ON (step S36). As a result, the two-way solenoid valve 74 is closed and the two-way solenoid valve 75 is opened.

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

When the water level of the concentrated water stored in the drainage tank 45 reaches a predetermined value, for example, an alert is issued to the manager of the hand-washing device 1. Upon confirming the alert, the administrator discards the water stored in the drainage tank 45.

The control unit 60 continues the process of step S36 for a predetermined time (step S37), and turns off the two-way solenoid valves 74 and 75 after the lapse of the predetermined time. As a result, the two-way solenoid valve 74 is opened and the two-way solenoid valve 75 is closed.
By opening the two-way solenoid valve 74 and closing the two-way solenoid valve 75 in this way, 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).

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

The purification unit 40 repeats these treatments, purifies the water drained by the drainage unit 30, and stores it in the water storage tank 46.

(Treatment to remove water in the water storage tank 46)
Next, the process of removing the water in the water storage tank 46 will be described.
The hand-washing device 1 has portability, and the installation location can be arbitrarily changed as needed. When transporting the hand-washing device 1, in order to facilitate the transport operation, a process of removing water in the water storage tank 46 to reduce the weight of the hand-washing device 1 is performed.
Further, regardless of the presence or absence of the transport work, the work of removing the water in the water storage tank 46 is performed when the hand-washing device 1 is stored for a long period of time, or when the hand-washing device 1 is tightened.

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

Specifically, the administrator causes the infrared sensor 23 of the faucet 12 to detect the finger while the spout 13 of the faucet 12 is located above the outside of the housing 2. When the finger is detected by the infrared sensor 23, the control unit 60 operates the water discharge pump 21 of the water discharge unit 20 to discharge water from the faucet 12.

The administrator keeps the detection of the fingers and empties the water storage tank 46 by discharging all the washing water in the water storage tank 46 from the water discharge port 13.
In the second state, even if the control unit 60 directly operates the water discharge pump 21 without using the infrared sensor 23 of the faucet 12, all the washing water in the water storage tank 46 is discharged from the water discharge port 13. good.

Further, the first state and the second state may be switched manually or automatically. For example, in the first state, the administrator manually moves the spout 13 of the faucet 12 located above the hand-washing tank 11 upward outside the housing 2. When the hand-washing device 1 is in the first state, the hand-washing device 1 shifts from the first state to the second state in response to moving the spout 13 of the faucet 12 upward outside the housing 2. May be.
Further, for example, the administrator inputs a predetermined command in the first state. Then, the spout 13 of the faucet 12 located above the hand-washing tank 11 automatically moves upward outside the housing 2.

Further, the output of the notification such as an error 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, the hand-washing indicator is not provided in a certain amount or more so that the user can discharge water for washing the hands from the spout 13 of the faucet 12. When the hand-washing device 1 is in the second state, the error or the like may not be notified even if the remaining amount of the water storage tank 46 or the like falls below a certain amount while notifying the error by causing the 15 to emit a predetermined light. ..

Further, the mode of discharging water from the spout 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, after a certain period of time has passed since the water was discharged from the water discharge port 13, the infrared sensor 23 was detecting the user's finger, but the water discharge was terminated (hand-washing). Therefore, the time for discharging water may be within a certain period of time), and in the second state, the water discharge from the spout 13 may not be stopped regardless of the passage of time.

<Display mode of hand-washing indicator 15 and control processing>
Next, the display mode of the hand-washing indicator 15 and the control process will be described. FIG. 7 is a diagram illustrating a display mode of the hand-washing indicator 15. FIG. 8 is an explanatory diagram showing a control process of the hand-washing indicator 15.

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

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

Then, as shown in FIG. 7B, when all the LED lights are turned on (step S44), the control unit 60 maintains the lighting state for a predetermined time thereafter. After a lapse of a predetermined time, as shown in FIG. 7C, the control unit 60 turns off the LED lights in a clockwise order from the LED lights located near the base of the faucet 12 (step S45).
At this time, the control unit 60 turns off all the LED lights in, for example, about 30 to 40 seconds.

The hand-washing device 1 may detect the user's finger by the infrared sensor 23 and turn off the hand-washing indicator 15 in order as described above in response to discharging water from the spout 13. As a result, the lighting state of the hand-washing indicator 15 changes with the discharge of water from the spout 13, so that the user can recognize the time from the discharge of water to the completion of hand-washing.
Further, when the infrared sensor 23 does not detect the user's fingers, the hand-washing device 1 causes the hand-washing indicator 15 to light a predetermined light (light-emitting in a predetermined color) so as to encourage the users around the hand-washing device 1 to wash their hands. It may be notified by (such as).

Then, as shown in FIG. 7D, when all the LED lights are turned off (step S45), the initial state is restored (step S41).
The series of time until the hand-washing indicator 15 is turned on in order and turned off in order is set to a generally recommended hand-washing time, for example, about 40 seconds. As a result, the hand-washing device 1 can present to the user a guideline for the hand-washing time in which a sufficient washing effect can be expected.

<Display mode of sterilization indicator 16 and control processing>
Next, the display mode of the hand-washing indicator 15 and the control process will be described. FIG. 9 is a diagram illustrating a display mode of the hand-washing indicator 15. FIG. 10 is an explanatory diagram showing a control process of the hand-washing indicator 15.

As shown in FIG. 10, when the UV sterilizer 80 is not in use, the LED light constituting the sterilization indicator 16 is turned off (step S51). The sterilization indicator 16 maintains the extinguished state when the carry-on item is not inserted into the UV sterilizer 80 (NO in step S52 in FIG. 10).

Then, as shown in FIG. 9A, when the portable item (smartphone) is inserted into the insertion port 81 of the UV sterilizer 80 and the portable item is pulled into the UV sterilizer 80 (YES in step S52), the control unit 60 , As shown in FIG. 9B, the LED light constituting the sterilization indicator 16 is blinked (step S53). At this time, the control unit 60 blinks the LED light in red, for example.

The control unit 60 shortens the cycle of blinking the LED light with time after the LED light starts blinking (step S54). The sterilization process in the UV sterilizer 80 corresponds to the control of the sterilization indicator 16. That is, the control unit 60 accelerates the blinking as the sterilization process in the UV sterilizer 80 progresses.

When the sterilization process in the UV sterilizer 80 is completed, as shown in FIG. 9D, the control unit 60 turns on the LED light with a color different from the blinking color so far (step S55). The LED light turns on, for example, green. This lighting means 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 lid and raises the portable item to a position where the user can take it out.

Then, when the carried item is taken out from the insertion slot 81 (YES in step S56), the control unit 60 turns off the LED light (step S51).
On the other hand, when the carried item is not taken out from the insertion slot 81 (NO in step S56), the control unit 60 maintains the lighting state of the LED light (step S55). By maintaining the lighting state of the LED light in this way, it is possible to prevent the user from forgetting to take out the portable item from the insertion slot 81.

The processing time of the sterilizing treatment in the UV sterilizing apparatus 80 may be the same as or equivalent to the lighting time of the hand-washing indicator 15. By doing so, it is possible to associate the time of the user's hand washing with the time of the sterilization treatment by the UV sterilizer 80.
As a result, it is possible to avoid a situation in which the user who has completed the hand-washing operation waits for the end of the UV sterilization treatment.

As described above, according to the hand-washing device 1 according to the present embodiment, in the hand-washing device 1 provided with the circulation unit 6 that purifies the wastewater from the hand-washing tank 11 and circulates it as washing water, the faucet 12 is discharged. The water outlet 13 can be arranged above the hand-washing tank 11 or above the outside of the housing 2.
Therefore, by arranging the spout 13 of the faucet 12 above the outside of the housing 2 and operating the pump of the circulation unit 6, it is possible to discharge the washing water to the outside of the hand washing device 1. ..

That is, for example, it is not necessary to attach a hose to the tip of the faucet 12 or take out a water storage tank 46 having a constant weight from the inside of the housing 2. This makes it possible to easily remove the washing water in the water storage tank 46 and reduce the difficulty in moving it.

Further, since the housing 2 has a cylindrical shape, when the hand-washing device 1 is transported, it can be easily transported by rolling the housing 2 while maintaining the state of being tilted at an angle.

Further, when the drum can is adopted as the housing 2, the design can be ensured while suppressing the manufacturing cost.

Further, the housing 2 may be transported in the form of rolling the housing 2 by installing the exercise portion on the road surface. In this case, the pretreatment filter 41, the posttreatment filter 43, and the UV sterilizer 80 installed outside the housing 2 as shown in FIG. 1B in order to make it easy to ground the housing 2 on the road surface and roll it. Etc. may be detachable from the housing 2. As a result, even if a specialized transportation staff is not operated to move the housing 2, the staff of the business operator (for example, the office floor of the business company, the store staff, etc.) who installs the housing 2 can do it by themselves. It becomes even easier to change the position of the housing 2. For example, it is assumed that the housing 2 is installed near the entrance of the store and the visitor is asked to wash his / her hands by the hand washing device 1 before entering the store. In this case, depending on the position where the housing 2 is installed, it may be difficult for a user who visits the store to find it (hence, it is difficult to increase the number of customers who enter the store after washing their hands). On the other hand, in the above-mentioned example, the store management staff and the like can search for a good position as an installation location of the housing 2 in order to provide an environment for the store to wash their hands.

Further, an access hole 4 is provided on the outer peripheral surface of the housing 2. Therefore, the access hole 4 can be used to easily perform maintenance of the hand-washing device 1 such as disposal work of concentrated water containing a large amount of impurities stored in the drainage tank 45 or replacement work of the reverse osmosis membrane 42.

Further, a door 3 is provided in the access hole 4. Therefore, by closing the door 3 during normal use, the appearance of the housing 2 can be improved.

Further, since the hand-washing device 1 includes the hand-washing indicator 15, it is possible to provide a high washing effect when the hand-washing device 1 is used by suggesting an appropriate hand-washing time to the user. Further, by using the hand-washing device 1, it is possible to enlighten the appropriate hand-washing time.

Further, since the hand-washing indicator 15 is arranged on the outside of the hand-washing tank 11 on the upper surface of the housing 2, it is possible to ensure the visibility of the hand-washing indicator 15 from the user who washes his / her hands using the hand-washing tank 11. can.

Further, the hand-washing indicator 15 is formed on the upper end edge of the hand-washing tub 11 so as to surround the hand-washing tub 11. Therefore, when the hand-washing indicator 15 is turned on, excellent designability can be exhibited.

Further, the post-processing filter 43 is arranged outside the housing 2 and is stored in a container whose inside can be visually recognized. Therefore, the state of the permeated water filtered by the post-treatment filter 43 can be visually recognized by the user from the outside.

As a result, the user can visually confirm that the circulation unit 6 has been properly cleaned, thereby giving the user a sense of security regarding the function of purifying the cleaning water by the circulation unit 6.

Further, the pretreatment filter 41 is also arranged outside the housing 2 and is stored in a container whose inside can be visually recognized. Therefore, the wastewater flowing into the pretreatment filter 41 and the water flowing out from the post-treatment filter 43 in a purified state can be compared. This makes it possible to give the user a sense of security even more effectively.

Further, the circulation unit 6 includes an intermediate tank 44, a drainage tank 45, a water storage tank 46, a water discharge unit 20, and a drainage unit 30. As a result, the intermediate water generated in the process of cleaning the wastewater can be appropriately separated and stored.

Further, since the hand-washing device 1 is provided with the UV sterilizing device 80, the user can use the hand-washing time to sterilize the carried items. In general, a portable item such as a smartphone that is always carried and operated by fingers has a remarkable adhesion of bacteria to its surface, and a habitual sterilization treatment is required from the viewpoint of hygiene. By sterilizing the surface of the smartphone with the UV sterilizer 80, such a problem can be solved.

Further, the UV sterilizer 80 is arranged on the side surface of the housing 2. Therefore, the user who washes his / her hands using the hand-washing device 1 can easily insert the carry-on item into the UV sterilizer 80.

Further, the UV sterilizer 80 is arranged as a part of the external module 7 attached to the outside of the housing 2. Therefore, the appearance of the housing 2 can be improved. Further, individual construction for attaching only the UV sterilizer 80 to the housing 2 becomes unnecessary.

Further, the hand-washing device 1 includes a sterilization indicator 16. Therefore, the progress of the sterilization process can be presented to the user. As a result, the convenience of the user can be ensured.

Further, the sterilization indicator 16 is arranged outside the hand-washing tank 11 on the upper surface of the housing 2. Therefore, the visibility of the user to the sterilization indicator 16 can be ensured.

Further, the sterilization indicator 16 is arranged between the hand-washing tank 11 and the external module 7. Therefore, the user who has washed his / her hands using the hand-washing tank 11 can easily confirm the display of the progress state by the sterilization indicator 16 in the process of confirming the state of the UV sterilization device 80 for sterilization treatment. As a result, the convenience of the user can be further ensured.

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

Further, the pretreatment filter 41 and the posttreatment filter 43 are stored in a visible container and arranged outside the housing 2.
When the membrane filtration pump 47 operates during the operation of the drainage pump 32, the drainage pump 32 operates to allow the drainage to flow into the pretreatment filter 41, and the membrane filtration pump 47 operates to allow the permeated water to flow into the posttreatment filter 43. The user can check the situation from the outside at the same time.

As a result, it is possible to visually convey to the user how the circulating water is washed and circulated inside the housing 2, and the user can use the hand-washing device 1 with peace of mind.

<Modification example>
Next, the hand-washing device 1 according to the modified example will be described. In this modification, the control unit 60 has a function of automatically controlling the first state and the second state of the faucet 12.

In this modification, a motor capable of rotating the faucet 12 is provided at the base of the faucet 12. Then, the control unit 60 drives the motor by the input to the control unit 60 from the outside, and the faucet 12 is rotated around the base unit, so that the first state and the second state are switched.

In the first state, the control unit 60 performs the wastewater treatment, the cleaning treatment, and the water discharge treatment as described above.
On the other hand, in the second state, the control unit 60 operates the water discharge unit 20 without performing wastewater treatment and cleaning treatment, and causes water to be discharged from the faucet 12 in order to remove the water stored in the water storage tank 46. Perform the water discharge treatment, which is a step.

According to this modification, the control unit 60 automatically controls the first state and the second state of the faucet 12. In the first state, the hand-washing device 1 can be normally used. In the second state, the washing water in the water storage tank 46 can be removed. Thereby, by automatically controlling the direction of the faucet 12, the washing water in the water storage tank 46 can be removed more easily.

<Other variants>

For example, based on the hand-washing device usage history data 931, the number of times of drug discharge since the previous maintenance date and time of the drug tank is accumulated and stored as "the number of hand-washing since the last maintenance" of the drug tank.

The item "remaining hand-washing count" is information on the remaining hand-washing count that can be performed until the next maintenance time comes for the member corresponding to each maintenance item. The item "remaining hand-washing count" is a numerical value obtained by subtracting the item "hand-washing count since the last maintenance" from the item "durable hand-washing count". For example, the pretreatment filter can perform 50 hand-washing with one replacement, and stores "20 times" as the "remaining hand-washing count" when 30 hand-washing has been performed since the previous replacement.

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

The maintenance control unit 94 adds the read identification information to a new record of the item “member identification information” of the member management data 932. At this time, the maintenance control unit 94 determines whether or not the read identification information complies with a predetermined rule. The prescribed rules may be changed according to the release date of the member. If the read identification information does not comply with a predetermined rule, the maintenance control unit 94 indicates to the exchanger that the exchanged member is not appropriate.

<Operation>
Hereinafter, the operation of controlling the first instruction unit and the second instruction unit by the maintenance unit will be described.
FIG. 18 is a diagram showing a flow of processing for controlling the first instruction unit 91 and the second instruction unit 92.

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

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

In step S183, the maintenance control unit 94 determines the output mode 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 of each maintenance item based on the remaining number of hand-washing of each maintenance item, and further determines the necessity of maintenance of the hand-washing device.

For example, the maintenance control unit 94 extracts the minimum value from the remaining number of hand washings for each maintenance item. When the extracted minimum value is 15 times or more, the maintenance control unit 94 determines that each maintenance item and the necessity of maintenance of the hand-washing device are "maintenance-free".

Further, when the minimum value is less than 15 times and 5 times or more, the maintenance control unit 94 determines that the maintenance item corresponding to the minimum value and the necessity of maintenance of the hand-washing device are "maintenance preparation". ..

Further, when the minimum value is less than 5 times and once or more, the maintenance control unit 94 determines that the maintenance item corresponding to the minimum value and the necessity of maintenance of the hand-washing device are "maintenance required". do.

Further, the maintenance control unit 94 stops the operation of the hand-washing device when the minimum value is 0 times. The maintenance control unit 94 determines that the maintenance item corresponding to the minimum value and the necessity of maintenance of the hand-washing device are "not restarted unless maintenance is performed".

In step S184, the maintenance control unit 94 outputs the first and second instruction information in the output mode determined in step S183 by the first and second instruction units.

Specifically, when it is determined in step S183 that the maintenance necessity of each maintenance item and the hand-washing device is "maintenance unnecessary", the maintenance control unit 94 turns on, for example, the first instruction unit 91 in blue, and the first instruction unit 91 is turned on. 2 Information indicating that maintenance is not required is displayed on the indicator 92. For example, the second instruction unit 92 displays the identification number “00” indicating that maintenance is not required.

Further, when it is determined in step S183 that the maintenance item corresponding to the minimum value and the necessity of maintenance of the hand-washing device are "maintenance preparation", the maintenance control unit 94, for example, lights the first instruction unit 91 in yellow. Then, the identification number of the maintenance item is displayed on the second instruction unit 92.

Further, when it is determined in step S183 that the maintenance item corresponding to the minimum value and the necessity of maintenance of the hand-washing device are "maintenance required", the maintenance control unit 94 displays, for example, the first instruction unit 91 in red. It is turned on and the identification number of the maintenance item is displayed on the second indicator 92.

Further, when it is determined in step S183 that the maintenance item corresponding to the minimum value and the necessity of maintenance of the hand-washing device are "not restarted unless maintenance is performed", the maintenance control unit 94 may, for example, use the first instruction unit 91. Flashes in red, and the identification number of the maintenance item is displayed on the second indicator 92.

The threshold value for the remaining number of times is not limited to 15 times and 5 times as shown above. The threshold value may be larger or smaller than these.
In addition, although we are trying to issue gradual alerts such as "maintenance not required", "maintenance preparation", "maintenance required", and "restart without maintenance", the gradual alert is not limited to these. .. The number of stages may be larger or smaller than these.

Further, when the minimum value becomes 0 times, the operation of the hand-washing device is stopped, but when the minimum value becomes 0 times, the operation of the hand-washing device does not necessarily have to be stopped. For example, it may be possible to use it several times even after the minimum value becomes 0 times. When the use is continued without maintenance even after the minimum value becomes 0 times, the maintenance control unit 94 strongly urges maintenance.

FIG. 18 illustrates that the control processing of the first and second instruction units is performed based on the remaining number of hand washings, but the present invention is not limited to this. The first and second indicator units may be controlled as follows. It should be noted that any control process may be used for control, or a plurality of control processes may be used in combination.

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

For example, the maintenance control unit 94 acquires the sensing result of each sensor from the filter sensing data 933, and determines the degree of wear of the pretreatment filter 41, the reverse osmosis membrane 42, the posttreatment filter 43, etc. included in the circulation unit 6. For example, when the electric conductivity detected by the EC / temperature sensor installed after the reverse osmosis membrane 42 exceeds a predetermined value, the maintenance control unit 94 is clogged with the reverse osmosis membrane 42 and the replacement time is set. Judge that it will arrive. The maintenance control unit 94 lights the first instruction unit 91 in red, and displays the identification number corresponding to the reverse osmosis membrane 42 on the second instruction unit 92.

Further, the maintenance control unit 94 has a pretreatment filter 41 and a reverse osmosis membrane 42 included in the circulation unit 6 when a predetermined behavior, for example, a behavior indicating an abnormality of the filter occurs in the sensing result acquired from the filter sensing data 933. And it is determined that an abnormality has occurred in the post-processing filter 43 or the like. The maintenance control unit 94 lights the first instruction unit 91 in red, and displays the identification number corresponding to the corresponding filter on the second instruction unit 92.

(B) Control based on the remaining amount of liquid The remaining amount of liquid is detected by installing a sensor that detects the water level in the container that stores the liquid. The maintenance unit 9 controls the outputs of the first instruction unit 91 and the second instruction unit 92 based on the remaining amount of the liquid.

For example, a water level sensor for detecting the remaining amount of the drug is provided in the drug tank 50, and when the sensing result of the water level sensor is lower than a predetermined value, the maintenance control unit 94 determines that the drug needs to be replenished. The maintenance control unit 94 lights the first instruction unit 91 in red, and displays the identification number corresponding to the medicine tank 50 on the second instruction unit 92.

(C) Control based on the abnormality detection result of the sterilizer A detection means for detecting the abnormality generated in the sterilizer is installed. The maintenance unit 9 controls the outputs of the first instruction unit 91 and the second instruction unit 92 based on the abnormality detection by the sterilizer.

For example, the maintenance control unit 94 acquires the usage history of the UV sterilizer 80 from the UV sterilizer 80. When the UV sterilizer 80 detects that an abnormality has occurred in the irradiation of ultraviolet rays, the maintenance control unit 94 determines that maintenance of the UV sterilizer 80 is necessary. The maintenance control unit 94 lights the first instruction unit 91 in red, and displays the identification number corresponding to the UV sterilizer 80 on the second instruction unit 92.

Further, 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 that an abnormality has occurred in the irradiation of ultraviolet rays, the maintenance control unit 94 determines that maintenance of the UV sterilization unit 22 is necessary. The maintenance control unit 94 lights the first instruction unit 91 in red, and displays the identification number corresponding to the UV sterilization unit 22 on the second instruction unit 92.

Through the above series of processes, the maintenance unit 9 can appropriately inform the maintenance information of the hand-washing device by the first instruction unit 91 and the second instruction unit 92. As a result, the person in charge of maintenance can appropriately and efficiently perform maintenance of the hand-washing device.

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

<Display example>
