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

The water discharge pump 21 is arranged behind the water storage tank 46 provided in the purification unit 40 . The water discharge pump 21 is operated under the control of the control section 60 to send water stored in the water storage tank 46 to the UV sterilization section 22 .
For example, the control unit 60 operates the water discharge pump 21 at a predetermined timing or when the infrared sensor 23 detects an object. Specifically, for example, the control unit 60 activates the water discharge pump 21 at a predetermined timing while the infrared sensor 23 is not detecting an object. In this embodiment, the predetermined timing is, for example, as follows.
・The preset time has come ・Preset period (for example, 1 hour)
- A preset time (period) has elapsed since the water discharge pump 21 was last driven. - The usage pattern of the device is predicted, and the time determined to be necessary for the maintenance of the device has elapsed. The amount of time deemed necessary for equipment maintenance has passed based on the state of the water quality in the tank.

Stopping the operation of the water discharge pump 21 at a predetermined timing is not limited to detection of an object by the infrared sensor 23 . For example, the control unit 60 stops the operation of the water discharge pump 21 when the user is about to wash his/her hands using the hand washing device 1 .

Specifically, for example, when a monitoring device is arranged around the hand washing device 1, the operation of the water discharge pump 21 may be stopped based on the monitoring data acquired by the monitoring device. For example, when it is determined based on the monitoring data acquired by the monitoring device that the user approaches the hand-washing device 1 , the control section 60 stops the operation of the water discharge pump 21 . Further, for example, the control unit 60 may stop the operation of the water discharge pump 21 in response to the user placing a carry-on item in the UV sterilization device 80 . Further, for example, when an object is detected by the infrared sensor 52 of the dispenser 14, the controller 60 may stop the water discharge pump 21 from operating.

Further, for example, the control unit 60 operates the water discharge pump 21 while the infrared sensor 23 is detecting the object. When the infrared sensor 23 no longer detects the object, the controller 60 stops the water discharge pump 21 .

The control unit 60 stores, for example, data related to the water circulated by the operation of the water discharge pump 21 at a predetermined timing and data related to the water circulated by the operation of the water discharge pump 21 in response to detection of an object by the infrared sensor 23.

Also, the predetermined position may be set based on the operation log of the inserted smartphone. In this way, by irradiating ultraviolet rays intensively on particularly dirty areas, it is possible to shorten the time required for sterilization.

For example, the hand-washing device 1 may communicate with a user's carrying item (for example, a device having a communication function such as a smartphone) to acquire information about the carrying item or information about the user.

Specifically, (1) when the hand washing device 1 is provided with a communication unit that communicates with a smartphone or the like by short-range wireless communication (NFC (Near Field Communication) using an IC chip or the like, high-speed wireless communication standard, etc.), Before the user sterilizes the smartphone with the UV sterilizer 80 in the hand washing device 1 , first, the smartphone is placed at a predetermined position on the hand washing device 1 . As a result, the smartphone transmits predetermined information to the hand washing device 1 .

Here, the predetermined information includes smartphone model information, smartphone user attribute information (e.g., employee code when the user is an employee, and user code when the user is a general consumer). Age group, member number information when registering for services provided by stores, information used for payment processing (user identification information for payment applications, credit card information, etc.), user's smartphone operation This includes information such as the operation log (coordinates of touch screen contact, application operation history, etc.).Like these, the user may be able to set the range in which information is provided from the smartphone to the hand washing device 1), etc. may be read by the hand-washing device 1.

In addition, (2) the hand-washing device 1 is managed by an external server or the like, and is capable of communicating with the external server or the like. A two-dimensional code such as a QR code (registered trademark) containing information identifying the hand washing device 1 (for example, a URL containing identification information of the hand washing device 1) is pasted on the hand washing device 1 or displayed on the screen. . The user's smartphone reads the two-dimensional code, and the smartphone communicates information including the identification information of the hand washing device 1 with an external server or the like, so that the external server or the like sends the hand washing device 1 information such as the model of the smartphone. may be sent.

In addition, (3) when the hand-washing device 1 has a reading unit (optical scanner, etc.) that reads a two-dimensional code (including information on the model of the smartphone, etc.) displayed on the smartphone, etc., the user can A two-dimensional code may be displayed and read by the hand-washing device 1 .

As described above, the example in which the hand washing device 1 and the smartphone wirelessly communicate 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 sterilization device 80 irradiates the smartphone with ultraviolet light, based on the model information of the smartphone. For example, the position where the home button is placed on a smartphone (smartphone size and the position of the home button are defined depending on the smartphone model), and the position from the bottom to the center of the screen when the user operates the smartphone while holding it vertically. (range where fingers frequently touch when the user operates the smartphone while holding it vertically) It is also possible to preferentially irradiate the area with ultraviolet light. For example, when the hand washing device 1 sets the time for sterilization by the UV sterilization device 80 (ultraviolet irradiation time) to be within a certain time in conjunction with the time for hand washing, the UV sterilization device 80 gives priority within the certain time. It is also possible to determine the range of target irradiation as described above.

Further, the hand-washing device 1 may determine the hand-washing time and the sterilization time by the UV sterilization device 80 based on the user's 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, by making the hand washing device 1 read the information of the relevant person, hand washing according to the attribute of the related person Time, the time for sterilization by the UV sterilizer 80 may be set. Depending on the user, there may be a case where hand washing and sterilization of belongings are especially required, such as a job type that is assumed to have a lot of contact with people. As a result, the hand-washing device 1 transmits to an external server or the like a log of the time when the employee or the like performed hand-washing and sterilization of the belongings with the hand-washing device 1 . When entering/leaving the facility is managed by the external server or the like, entry/leaving may be controlled based on the history of the user's washing of hands with the hand washing device 1 . For example, even if the user does not wash his or her hands with the hand-washing device 1, there may be rooms that the user can enter, and there may be rooms that the user cannot enter if the user does not wash their hands or the like. As a result, the administrator of the facility can restrict entry and exit based on the user's history of washing his or her hands with the hand-washing device 1 .

The UV sterilizer 80 turns off the UV light after turning on the UV light for a preset period. The preset time period corresponds, for example, to the generally recommended hand-washing times.
When the UV sterilizer 80 turns off the UV light, it opens the lid and raises the pedestal to a predetermined position. The predetermined position represents a position where a part of the smart phone protrudes from the insertion opening 81 so as to be accessible by the user.
This allows the user to sterilize the smartphone while inserting and removing the smartphone without touching the UV sterilizer 80 .
The hand-washing device 1 may discharge water from the spout 13 in response to the setting of the belongings on 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 near the insertion port 81 . The sterilization indicator 16 displays, for example, the progress of the sterilization process of the belongings by the UV sterilizer 80 . The sterilization indicator 16 operates, for example, when the lid of the UV sterilizer 80 is closed, and is installed so as to illuminate the closed lid obliquely from above. The sterilization indicator 16 is realized by LED lights, for example. A sterilization indicator 16 may be embedded in the lid. The lighting mode of the sterilization indicator 16 and control processing will be described later.

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

(Water discharge process of 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 controller 60 turns off the water discharge pump 21 (step S11).

The controller 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 puts his/her hand into the hand-washing tub 11 and causes the infrared sensor 23 arranged at the tip of the faucet 12 to detect the finger.

When the infrared sensor 23 detects the finger (YES in step S12), the controller 60 operates the water discharge pump 21 (step S13).
The water discharge pump 21 allows the water stored in the water storage tank 46 to pass through the UV sterilization section 22 . The UV sterilization unit 22 irradiates the water sent from the water discharge pump 21 with ultraviolet rays, thereby sterilizing the water. The water that has passed through the UV sterilization unit 22 is spouted from the spout 13 of the faucet 12 as cleansing water.
On the other hand, when the finger is not detected by the infrared sensor 23 in step S12 (NO in step S12), the water discharge pump 21 does not operate (step S11).

The controller 60 determines whether or not an object has been detected by the infrared sensor 23 (step S14). When the user terminates the hand-washing device 1 or causes the dispenser 14 to discharge medicine, the user separates his/her fingers from the infrared sensor 23 arranged at the tip of the faucet 12 .
Control part 60 stops water discharge pump 21 according to non-detection of a finger by infrared sensor 23 (NO of Step S14) (Step S11).

On the other hand, if the finger is not detected by the infrared sensor 23 in step S14 (YES in step S14), the controller 60 continues to operate the water discharge pump 21 (step S13).
The water discharge unit 20 repeats these processes and discharges cleansing water from the faucet 12 .
The controller 60 may measure the time during which the infrared sensor 23 detects the finger, and stop the water discharge when the finger is detected for a certain period of time. Further, the control unit 60 may stop water discharge in response to completion of sterilization by the UV sterilizer 80 while discharging 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 tub 11 (step S21).
Then, when the washing water spouted from the faucet 12 toward the hand-washing tub 11 is drained from the drain port 17 of the hand-washing tub 11, the capacitance sensor 31 detects the drainage (step S22).

When the capacitance sensor 31 detects drainage (YES in step S22), the controller 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 controller 60 does not operate the drainage pump 32 (step S21).

In step S<b>23 , 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 . A pressure sensor 33 detects the pressure of the water sent to the pretreatment filter 41 . The flow rate sensor 34 detects the flow rate of water pretreated by the pretreatment filter 41 .

After step S23, when the capacitance sensor 31 detects that there is no longer any waste water flowing from the drain port 17 (NO in step S24), the controller 60 stops the drain pump 32 (step S21).
On the other hand, in step S24, when the capacitance sensor 31 detects that the wastewater continues to flow from the drain port 17 (YES in step S24), the controller 60 continues to operate the drain pump 32. (Step S23).

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

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

The controller 60 determines whether the drain pump 32 is in operation (step S32).
When the drainage pump 32 is in operation (YES in step S32), the controller 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, if the drainage pump 32 is not in operation (NO in step S32), the controller 60 keeps the membrane filtration pump 47 in operation (step S31).

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

The post-treatment filter 43 applies post-treatment to the permeated water. The permeated water post-treated by the post-treatment filter 43 is added with hypochlorous acid 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 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 controller 60 determines whether the drainage pump 32 is operating (step S35). If the drainage pump 32 is in operation (YES in step S35), the controller 60 continues to operate the membrane filtration pump 47 (step S33).

On the other hand, in step S34, when 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 controls the two-way solenoid valve 74 and the two-way solenoid valve 75 is turned ON (step S36). Thereby, the two-way solenoid valve 74 is closed and the two-way solenoid valve 75 is opened.

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

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

The control unit 60 continues the process of step S36 for a predetermined period of time (step S37), and turns off the two-way solenoid valves 74 and 75 after the predetermined period of time has elapsed. 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 controller 60 stops the membrane filtration pump 47 (step S31) after a predetermined time has elapsed (step S38).

The purification unit 40 repeats these processes to purify the water drained by the drainage unit 30 and stores it in the water storage tank 46 .

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

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, the controller 60 determines whether or not the dispenser 14 has been activated (step S42). When the user using the hand-washing device 1 holds his or her hand under the dispenser 14, the infrared sensor 52 of the dispenser 14 detects the hand or finger. When the finger is detected by the infrared sensor 52 , the controller 60 activates the drug pump 51 to eject the drug from the dispenser 14 .
If the dispenser 14 has been activated (YES in step S42), the controller 60 lights the hand washing indicator 15 (steps S43 to S44).

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

Then, as shown in FIG. 7B, when all the LED lights are turned on (step S44), the control section 60 maintains the lighting state for a predetermined time thereafter. After a predetermined period of time has elapsed, the control unit 60 turns off the LED lights in clockwise order, starting with the LED lights positioned 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 about 30 to 40 seconds, for example.

The hand-washing device 1 detects the user's fingers with the infrared sensor 23, and in response to water being discharged from the spout 13, turns off the hand-washing indicator 15 sequentially over time as described above. As a result, the lighting state of the hand wash indicator 15 changes as water is discharged from the spout 13, so that the user can recognize the time from water discharge to completion of hand washing.
In addition, 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 up in a predetermined manner (lights up in a predetermined color) so as to encourage users around the hand-washing device 1 to wash their hands. for example), etc.).

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).
A series of times until the hand-washing indicators 15 turn on in turn and turn off in turn is set to a generally recommended hand-washing time, for example, about 40 seconds. As a result, the hand-washing device 1 can present the user with an estimate of the hand-washing time at which a sufficient washing effect can be expected.

<Display Mode of Sterilization Indicator 16 and Control Processing>
Next, the display mode of the sterilization indicator 16 and control processing will be described. FIG. 9 is a diagram illustrating how the UV sterilizer 80 is used. FIG. 10 is an explanatory diagram showing control processing of the sterilization indicator 16. As shown in FIG.

As shown in FIG. 10, when the UV sterilizer 80 is not in use, the LED light constituting the sterilization indicator 16 is off (step S51). In a state in which no belongings are inserted into the UV sterilizer 80, the sterilization indicator 16 remains off (NO in step S52 of FIG. 10).

Then, as shown in FIG. 9, when a carried item (smartphone) is inserted into the insertion opening 81 of the UV sterilizer 80 and the carried item is pulled into the UV sterilizer 80 (YES in step S52), the control unit 60 , the lid of the insertion slot 81 is closed, and the LED light constituting the sterilization indicator 16 is blinked (step S53).

The control unit 60 shortens the cycle of blinking the LED light as time elapses after the blinking of the LED light is started (step S54). The sterilization process by the UV sterilization device 80 and the control of the sterilization indicator 16 correspond to each other. In other words, the controller 60 causes the blinking to advance faster as the sterilization process in the UV sterilizer 80 progresses.

After the sterilization process in the UV sterilization device 80 is finished, the controller 60 turns on the LED light (step S55). This lighting means the end of the sterilization process. After turning on the LED light for a predetermined time, the control unit 60 turns off the LED light (step S51).
When the sterilization process is completed, the UV sterilizer 80 turns off the UV light, opens the lid, and raises the carry-on item to a position where the user can take it out.

The processing time of the sterilization process in the UV sterilization device 80 may be the same as or equal to the lighting time of the hand washing indicator 15 . In this way, the user's hand-washing time and the sterilization processing time by the UV sterilizer 80 can be associated with each other.
As a result, it is possible to avoid a situation in which the user who has completed the hand-washing task waits for the end of the UV sterilization treatment.

As described above, the hand-washing device 1 according to the present embodiment includes the circulation unit 6 that purifies the drainage from the hand-washing tub 11 and circulates it as washing water.
For this reason, it is possible to realize hand-washing with a pre-filled volume of water that significantly exceeds the number of times expected from the volume of water.

That is, for example, it is not necessary to attach a hose to the tip of the faucet 12 or remove the water storage tank 46 of a certain weight from the inside of the housing 2 . As a result, the cleaning water in the water storage tank 46 can be easily removed and the difficulty in moving it can be reduced.

Moreover, when a drum can is adopted as the housing 2, designability can be secured while suppressing the manufacturing cost.

Moreover, since the housing 2 is provided with the handle 4 and the wheels 19 , the user can move the housing 2 by moving the wheels 19 while gripping the handle 4 . As a result, even if a specialized transportation staff is not operated to move the housing 2, the staff of the business operator who installs the housing 2 (for example, the office floor of the business company, store staff, etc.) can Changing the position of the housing 2 becomes even easier. For example, it is assumed that the housing 2 is installed near the entrance of the store, and visitors wash their hands with 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 users visiting the store to find it (and therefore, it is difficult to increase the number of customers who wash their hands before entering the store). On the other hand, in the above example, the management staff of the store or the like can search for a good position as the installation position of the housing 2 in order to provide an environment for customers to wash their hands.

A door 3 is provided on the outer peripheral surface of the housing 2 to allow access to the inside. Therefore, by opening the door 3, it is possible to easily perform maintenance of the hand washing device 1 such as disposal of concentrated water containing many impurities stored in the drain tank 45 or replacement of the reverse osmosis membrane 42. - 特許庁

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

Further, since the hand-washing indicator 15 is arranged outside the hand-washing tub 11 on the upper surface of the housing 2, the visibility of the hand-washing indicator 15 from the user who washes their hands using the hand-washing tub 11 can be ensured. can.

Moreover, a hand-washing indicator 15 is formed at the upper 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 design can be exhibited.

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

As a result, the user can visually confirm that the circulation unit 6 is properly washing, so that the user can feel secure about the washing water purification function of the circulation unit 6 .

The pretreatment filter 41 is also arranged outside the housing 2 and housed in a container whose interior is visible. Therefore, it is possible to compare the waste water flowing into the pretreatment filter 41 and the purified water flowing out of the posttreatment filter 43 . This makes it possible to more effectively give the user a sense of security.

Also, 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 sorted and stored.

In addition, since the hand-washing device 1 includes the UV sterilization device 80, the user can use the hand-washing time to sterilize the items to be carried. In general, mobile items such as smartphones, which are always carried and operated with fingers, have a significant amount of bacteria attached to their surfaces, and from a hygienic point of view, habitual sterilization treatment has been required. Such problems can be solved by sterilizing the surface of the smartphone with the UV sterilization device 80 .

A UV sterilizer 80 is also arranged in the housing 2 . Therefore, it is possible for a user who uses the hand-washing device 1 to wash his hands to easily insert his belongings into the UV sterilization device 80 .

The hand washing device 1 also includes a sterilization indicator 16 . Therefore, it is possible to present the progress of the sterilization process to the user. Thereby, user convenience can be ensured.

Also, a sterilization indicator 16 is installed near the insertion port 81 of the UV sterilization device 80 . Therefore, a user who has washed his/her hands using the hand washing tub 11 can easily check the progress displayed by the sterilization indicator 16 in the process of checking the state of the UV sterilization device 80 that is sterilizing. Thereby, user convenience can be further ensured.

Also, a step of operating the membrane filtration pump 47 when the drainage pump 32 is operating is executed. Therefore, the membrane filtration process by the reverse osmosis membrane 42 can be performed according to the generation of waste water. As a result, the flow rate of circulating water in the entire circulating system can be balanced while the capacities of the respective tanks are limited. Moreover, it is possible to efficiently perform the purification process.

A pre-processing filter 41 and a post-processing filter 43 are housed in a visible container and arranged outside the housing 2 .
When the membrane filtration pump 47 operates when the drainage pump 32 operates, the operation of the drainage pump 32 causes the waste water to flow into the pretreatment filter 41, and the operation of the membrane filtration pump 47 causes the permeated water to flow into the post-treatment filter 43. The user can simultaneously check the status and the status from the outside.

As a result, it is possible to visually inform the user that 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.

In the above-described embodiment, a case in which one infrared sensor is arranged in the spout 13 has been described as an example, but the present invention is not limited to this aspect. Four infrared sensors may be arranged in the cross direction at the water outlet 13 . This makes it possible for the user, who spouted cleansing water from the spout 13 at the start of hand-washing, to know in which direction the hand moved after getting the hand wet. If the user's actions after getting their hands wet can be grasped, it will be possible to grasp whether the user has properly used the medicine.

The hand-washing device 1 may sense how the user has moved his or her hand near the spout 13 in this way, and store a history of the movement of the user's hand. The hand-washing device 1 analyzes the hand-washing behavior of a plurality of users who use the hand-washing device 1 at the place where the hand-washing device 1 is installed by transmitting a log of the user's hand movements to an external server or the like. can be done. For example, it is possible to analyze whether or not there is a tendency for users who use the hand washing device 1 installed in a certain place to properly wash their hands.

A sensor, such as a human sensor, may be arranged on the front surface of the housing 2 of the hand-washing device 1 to determine the presence or absence of a person. The motion sensor makes it possible to acquire the length of stay in front of the hand-washing device 1 of the user who used the hand-washing device 1 .

In the above embodiment, an example 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 has been described. .

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 have to be stored in a container whose inside is visible.

The shape, structure, display mode, and control processing of the hand-washing indicator 15 can be arbitrarily changed. Moreover, the hand-washing device 1 may not include the hand-washing indicator 15 .

The shape, structure, display mode, and control processing of the sterilization indicator 16 can be changed arbitrarily. The sterilization indicator 16 may be provided on the UV sterilization device 80 . Moreover, the hand-washing apparatus 1 does not have to be equipped with the sterilization indicator 16 .

The configuration of the purification unit 40 can be changed arbitrarily. For example, the post-processing filter 43 may be omitted, or other filters may be additionally employed.

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

<Overall composition>
The overall configuration of the hand-washing device according to the second embodiment will be described. FIG. 11 is a block diagram showing an example of the configuration of the hand-washing device according to the second embodiment.

As shown in FIG. 11, the hand-washing device includes a circulation unit 6, a chemical tank 50, a UV sterilizer 80, and a maintenance unit 9. Although not shown, the hand-washing device includes a housing 2, a hand-washing tub 11 provided in a part of the housing, and a washing water jet as in the first embodiment so as to realize hand-washing. It includes a faucet 12 that serves water, a dispenser 14, and the like.

The configurations of the circulation unit 6, the chemical tank 50, and the UV sterilizer 80 are the same as those of the first embodiment, and therefore will not be described repeatedly.

The maintenance unit 9 has a structure for controlling maintenance work for the hand-washing device, and is connected to the circulation unit 6, the chemical tank 50, and the UV sterilization device 80, respectively. The configuration of the maintenance unit 9 will be described below.

<Configuration of maintenance unit>
FIG. 12 is a block diagram showing the configuration of the maintenance unit 9. As shown in FIG. As shown in FIG. 12 , the maintenance unit 9 includes a first instruction section 91 , a second instruction section 92 , a storage section 93 and a maintenance control section 94 .

The first instruction unit 91 is installed at a position visible to the user in the housing, and outputs first instruction information so as to notify the need for maintenance of the hand washing device. The necessity of maintenance here means whether or not it is necessary to perform maintenance work on the hand washing device. The necessity of maintenance of the hand-washing device is determined based on the necessity of maintenance of each maintenance item described later.

The first indicator 91 is composed of, for example, the hand-washing indicator 15 of the first embodiment, and is formed at the upper edge of the hand-washing tub so as to surround the hand-washing tub. Also, the first instruction unit 91 may be, for example, the sterilization indicator 16 of the first embodiment installed near the insertion port 81 of the UV sterilization device 80 . In other words, the first instruction unit 91 is not limited to the above example as long as it is an indicator installed at a position that can be visually recognized by the user who is washing his/her hands. For example, the first instruction unit 91 may be installed at a position near the user on the upper surface of the housing 2 , outside the hand washing tub 11 .

The first indicator 91 is composed of a light-emitting element and can be lit in a plurality of lighting modes. The first instruction unit 91 changes the lighting mode and outputs first instruction information based on the necessity of maintenance. The lighting mode referred to herein includes lighting color, lighting luminance, presence/absence of blinking, and the like. For example, the first instruction unit 91 outputs the first instruction information by turning on the blue light when the maintenance of the hand washing device is unnecessary, turning on the yellow light when the maintenance time comes after a predetermined period of time, and turning on the maintenance time. Lights up red when the is coming soon, and flashes red when the operation has stopped due to lack of maintenance.

Also, the first instruction unit 91 operates when the user is washing his/her hands.

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

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

In step S182, the maintenance control unit 94 calculates the remaining number of times of hand washing that can be performed until the next maintenance timing 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 last maintenance from the durable number of hand washings.

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 times of hand washing. Specifically, the maintenance control unit 94 determines the necessity of maintenance for each maintenance item based on the remaining number of times of hand washing for each maintenance item, and further determines the necessity of maintenance for the hand washing device.

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

In addition, when 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 necessity of maintenance of the hand washing device are "maintenance preparation". .

In addition, when the minimum value is less than 5 times or more than 1 time, the maintenance control unit 94 determines that the maintenance item corresponding to the minimum value and the necessity of maintenance of the hand washing device are "maintenance required". do.

Further, when the minimum value is 0 times, the maintenance control unit 94 stops the operation of the hand-washing device. 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 "not restarted unless maintenance is performed".

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.

Specifically, when it is determined in step S183 that each maintenance item and the need for maintenance of the hand-washing device are "maintenance unnecessary", the maintenance control unit 94, for example, lights the first instruction unit 91 in blue, and 2. Information indicating that maintenance is unnecessary is displayed on the instruction section 92 . For example, the second instruction unit 92 displays the identification number "00" indicating that maintenance is unnecessary.

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

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

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

It should be noted that the threshold for the remaining number of times is not limited to 15 times and 5 times as shown above. The threshold may be larger or smaller than these.
Also, alerts are issued in stages such as "maintenance not required", "maintenance ready", "maintenance required", and "won't restart unless maintenance is performed", but the tiered alerts are not limited to these. . The number of stages may be greater than or less than these.

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

Although FIG. 18 exemplifies that the control processing of the first and second instruction units is performed based on the remaining number of times of hand washing, the present invention is not limited to this. You may control the 1st, 2nd instruction|indication part as follows. Any control process may be used for control, or a plurality of control processes may be used together.

(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 the water passing through the filter is provided in the flow path of the filter to detect the degree of wear of the filter. . The maintenance unit 9 controls the outputs of the first indicator 91 and the second indicator 92 based on the degree of filter wear.

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 pretreatment filter 41, the reverse osmosis membrane 42, the posttreatment filter 43, etc. provided in the circulation unit 6. For example, when the electrical conductivity detected by the 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 the replacement time is reached. Determined to arrive. The maintenance control unit 94 lights the first indicator 91 in red, and displays the identification number corresponding to the reverse osmosis membrane 42 on the second indicator 92 .

In addition, when the sensing result obtained from the filter sensing data 933 shows a predetermined behavior, for example, a behavior indicating the occurrence of an abnormality in the filter, the maintenance control unit 94 controls the pretreatment filter 41 and the reverse osmosis membrane 42 included in the circulation unit 6. 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 indicator 91 in red, and displays the identification number corresponding to the corresponding filter on the second indicator 92 .

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

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

(c) Control based on the results of detection of anomalies in the sterilizer A detection means is installed to detect anomalies that have occurred in the sterilizer. The maintenance unit 9 controls outputs of the first instruction section 91 and the second instruction section 92 based on the detection of abnormality in the sterilizer.

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

Also, for example, the maintenance control unit 94 acquires the usage history of the UV sterilization unit 22 from the UV sterilization unit 22 . When notified by the UV sterilizer 22 that an abnormality has occurred in the irradiation of ultraviolet rays, the maintenance control unit 94 determines that maintenance of the UV sterilizer 22 is necessary. The maintenance controller 94 lights the first indicator 91 in red, and displays the identification number corresponding to the UV sterilizer 22 on the second indicator 92 .

Through the series of processes described above, the maintenance unit 9 can appropriately notify the information regarding the maintenance of the hand-washing device through the first instruction section 91 and the second instruction section 92 . Thereby, the person in charge of maintenance can perform the maintenance of the hand-washing device appropriately and efficiently.

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

<Display example>
Display examples of the first instruction section 91 and the second instruction section 92 will be described.

FIG. 19 is a diagram illustrating an example of a display mode of the first instruction section; In FIG. 19, the first instruction unit 91 is composed of the hand-washing indicator 15 of the first embodiment, and displays an indication of the hand-washing time when the user is washing his/her hands. Communicate the need for maintenance.

For example, the lighting color of the hand-washing indicator 15 is set to blue when the maintenance of the hand-washing device is not required, and the lighting color of the hand-washing indicator 15 is set to red when the maintenance of the hand-washing device is required. As shown in FIG. 19, when the dispenser 14 is activated, the hand-washing indicators 15 are displayed in clockwise order from the LED lights located near the base of the faucet 12 in top view so as to indicate the approximate time for hand-washing. Along with lighting, it lights up in a predetermined color so as to notify the need for maintenance of the hand-washing device.

As a result, while the user is washing his/her hands, it is possible to notify the user of the need for maintenance of the hand-washing device in a manner that is easily visible to the user. Therefore, the user can grasp the maintenance status or sanitation status of the hand washing device. In addition, since the need for maintenance can be notified to the manager of the hand-washing device, the manager can be urged to perform the maintenance work appropriately.

FIG. 20 is a diagram showing an example of a display mode of the second instruction section. In FIG. 20, the second indicator 92 is composed of two 7-segment LEDs, and displays the identification number of the maintenance item to notify the maintenance item that requires maintenance. The second indicator 92 is not limited to being composed of two 7-segment LEDs. The second instruction unit 92 may be implemented in any manner as long as it can present maintenance items.

For example, as shown in FIG. 20 , when it is determined that the preprocessing filter 41 needs to be replaced, the identification number “02” of the preprocessing filter 41 is displayed on the second instruction section 92 . Also, if there is no maintenance item that requires maintenance, the identification number "00" may be displayed. Also, if a technical error occurs that cannot be dealt with by replacement, for example, a preset identification number "88" may be displayed.

As a result, it is possible to inform the manager of the hand-washing device of specific maintenance items that require maintenance. Therefore, the manager of the hand-washing device can appropriately perform maintenance work.

Further, the maintenance control unit 94 may determine whether or not the replaced member, for example, the filter, is proper based on the item “sensing result” of the filter sensing data 933 . For example, the pretreatment filter 41, the reverse osmosis membrane 42, and the posttreatment filter 43 have different flow characteristics depending on the materials used. That is, depending on the material used, the pressure or flow rate detected before or after the filter changes.

The maintenance unit 9 preliminarily stores general pressure values, flow values, or the like detected when the appropriate pretreatment filter 41, reverse osmosis membrane 42, and posttreatment filter 43 are attached, with a predetermined width. It is stored in the storage unit 93 . When the filter is replaced, the maintenance control section 94 controls, for example, the water discharge unit 20 to cause the faucet 12 to discharge cleansing water. The maintenance control unit 94 determines whether or not the pressure value or flow rate value detected at this time falls within a preset range of pressure values or flow rate values. If it does not fit, the maintenance control unit 94 presents to the replacer that the replaced member is not proper. Note that the preset pressure value, flow rate value, or the like may be updated to the latest value when the program is updated.
