[0023]
The control unit 21 is provided with water discharge control means 21A, mousse control means 21B, and drying control means 21C as functional means for controlling the operation of the cleaning apparatus.
FIG. 5 shows a flow chart of water discharge control. In the water discharge control means 21 </ b> A, when the detection output from the water discharge sensor 11 indicates that the sensor is ON, the water discharge control unit 21 </ b> A determines that it is a water discharge request from the user and drives the electromagnetic valve 41.

Then, water is discharged from the water discharge port 11B of the water discharge panel 11A.
[0024]
FIG. 6 shows a flow chart of the mousse control. When the detection output from the mousse sensor 12 indicates that the sensor is ON, the mousse control means 21B determines that it is a mousse discharge request from the user and drives the water soap pump 23 and the air pump 22 in parallel.
As a result, the cleaning liquid is pumped up from the water soap tank 24 by the water soap pump and supplied to the mousse panel 12 </ b> A through the water soap hose 25.

[0026]
Next, operation | movement of the hand-washing apparatus concerning this invention is demonstrated.
In the present embodiment, based on the basic control operation described above, when a user requests an operation, the requested operation is controlled by referring to the operation state of other operation and the detection output of the sensor. It is a thing.
The operation state of each operation is managed in the internal memory of the control unit 21 and can be commonly referred to by each functional unit. Also, the detection output of each sensor can be commonly referred to by each functional means.
[0027]
First, a first embodiment according to the present invention will be described with reference to FIG. FIG. 8 is a timing chart showing the control operation according to the first embodiment. This embodiment relates to the control of the drying operation requested after the mousse discharge operation.
In the drying control unit 21C of the control unit 21, when the detection output of the drying sensor 13 is turned ON after the water discharge operation is performed by the water discharge control unit 21A, the fan motor 31 is immediately activated at high speed (HIGH) as hot start control. Start driving. In this case, since the water droplets have a certain amount of weight and are unlikely to scatter compared to the mousse, they are driven at a high speed immediately after the start of driving.
[0028]
On the other hand, after the mousse discharge operation is performed by the mousse control means 21B, for example, when the detection output of the drying sensor 13 is turned ON before a predetermined time elapses, the air volume is gradually increased without driving at high speed, for example, Slow start control is performed in which the supplied power is increased with time to control the rotational speed of the fan motor 31. In this case, since the mousse is relatively light in weight and easily scattered, the mousse can be prevented from scattering immediately after the start of the drying operation by performing such slow start control.
In addition, since there is time until the air volume reaches a level at which the mousse scatters, the user can notice the hot air blowing and can move his hand away from the air outlet 13B, that is, the drying sensor 13, thereby detecting the drying sensor 13. The output is sensor OFF, and the scattering of the mousse adhering to the hand or the bowl portion 10A can be avoided.
[0029]
Note that the slow start control may also be applied when the detection output of the drying sensor 13 is turned ON after the hand washing apparatus has been unused for a long time. If the user who came to the hand-washing device accidentally or unknowingly turned on the drying sensor before discharging water or mousse, if the above hot start control is performed at the start of the drying operation, the hot air will be blown out at high speed. Some surprises are also possible.
[0030]
Therefore, when the user first performs a drying operation in the unused state, the user is not surprised by performing the slow start control.
For the unused state, the elapsed time t since the last use of the hand-washing device, for example, the elapsed time t after the end of the water discharge operation, the mousse discharge operation or the drying operation is the predetermined time t._sIt may be determined that it is in an unused state when it exceeds.
[0031]
Next, a second embodiment according to the present invention will be described with reference to FIG. FIG. 9 is a timing chart showing a control operation according to the second embodiment. This embodiment relates to the control of the drying operation requested after the mousse discharge operation.
In the first embodiment, the case where the slow start control is performed for the drying operation after the mousse discharge operation has been described. However, in the present embodiment, the predetermined period t after the mousse discharge operation is set._dThe reception of the drying sensor 13 is prohibited (for example, around 5 seconds).
As a result, even if the drying operation is performed after the mousse discharging operation, the hot air is blown after the mousse (bubbles) disappears to some extent, so that the scattering of the mousse can be suppressed.
[0032]
About the reception prohibition period of the drying sensor 13, the reception prohibition period may be terminated by a water discharge operation. This is because there is a high possibility that the mousse is washed away by the water discharged after the mousse is discharged. This allows the user to perform a smooth hand-washing operation. In this case, if the first embodiment is applied, the drying control is the hot start control because the water discharge operation is performed immediately before the drying control.
[0033]
Next, a third embodiment according to the present invention will be described with reference to FIG. FIG. 10 is a timing chart showing a control operation according to the third embodiment. This embodiment relates to the control of the mousse discharge operation requested after the drying operation.
Here, paying attention to the fact that warm air continues to be blown to some extent by the idling of the fan motor 31 and the internal pressure of the air duct 33 and the chamber 14 immediately after the end of the drying operation, the mousse control means 21B keeps constant after the drying operation ends. Period t_bThe reception of the mousse sensor 12 is prohibited (for example, around 2 seconds). Thereby, the mousse scattering by the warm air which remains immediately after completion | finish of drying operation can be avoided.
[0034]
Note that the mousse is scattered during the mousse discharge during the drying operation._aThe reception of the mousse sensor 12 is prohibited (for example, around 2 seconds). t_aFor t_bSimilarly to this, it is a period from when the fan motor 31 starts to rotate until the internal pressure of the air duct 33 and the chamber 14 rises to some extent and mousse scattering can occur.
[0035]
Next, a fourth embodiment according to the present invention will be described with reference to FIG. FIG. 11 is a timing chart showing a control operation according to the fourth embodiment. This embodiment relates to the control of the mousse discharge operation requested after the drying operation.
Here, a predetermined time t after the drying sensor 13 is turned ON and the drying operation is started._cIf the mousse sensor 12 is turned on before the lapse, the drying control unit 21C stops the drying operation and gives priority to the mousse discharge operation. Thereby, mousse scattering during the drying operation can be avoided.
[0036]
In this case, t_cIs a period from when the fan motor 31 starts to rotate until the internal pressure of the air duct 33 and the chamber 14 rises to some extent and mousse scattering can occur.
Also, after starting the drying operation, t_cWhen the mousse sensor 12 is turned on after the lapse (during the drying operation), the mousse control unit 12B may ignore the mousse discharge operation, and mousse scattering during the drying operation can be avoided.
[0037]
Next, a fifth embodiment according to the present invention will be described with reference to FIG. FIG. 12 is a timing chart showing a control operation according to the fifth embodiment. The present embodiment relates to control for preventing the scattering by limiting the amount of mousse discharged.
Here, the mousse control means 21B is provided with a mousse counter to count the number of times the mousse has been discharged, and when there is a mousse discharge request continuously for a predetermined number of times, the request is ignored.
[0038]
FIG. 12 shows a case where the number of times that the mousse can be continuously discharged is 2 times, and the mousse counter is subtracted in accordance with the mousse discharge operation. After the point when the value of the mousse counter becomes 0 (zero), the mousse discharge request is ignored.
Thus, since the number of times the mousse can be continuously discharged is limited, a large amount of mousse is not discharged by mistake or mischief, and the mousse can be prevented from being scattered in advance. Further, it is very effective when the mousse consumption can be reduced, the running cost can be reduced, and the hand-washing device is used frequently such that it is used by the public.
[0039]
This mousse discharge restriction may be canceled by a water discharge operation. For example, when the water discharge operation is performed during the period when the mousse counter is 0, it is highly possible that the previously discharged mousse has been discharged by the water discharge operation. do it.
Also, a predetermined time t from mousse discharge_wAfter the elapse of time, it is highly possible that the mousse bubbles have disappeared. Therefore, the mousse water discharge restriction may be canceled in the same manner as described above.
Thereby, the user can perform a smooth hand-washing operation.
[0040]
Next, a sixth embodiment according to the present invention will be described with reference to FIG. FIG. 13 is a timing chart showing a control operation according to the sixth embodiment. As in the fifth embodiment, the present embodiment also relates to control for preventing the scattering by limiting the amount of mousse discharged.
[0041]
Here, the mousse control means 21B manages the ON period of the mousse sensor, and the predetermined period t_MAXEven when the mousse sensor is turned on continuously, the mousse discharge operation is_MAXIt is intended to stop at.
Accordingly, a large amount of mousse is not discharged by mistake or mischief, and it is possible to avoid mousse scattering in advance. Further, it is very effective when the mousse consumption can be reduced, the running cost can be reduced, and the hand-washing device is used frequently such that it is used by the public.
[0042]
The ON period of the moose sensor 12 is a predetermined period t._TYPIf it is shorter, the predetermined period t_TYPOnly the mousse discharge operation may be performed. Thereby, the minimum amount of mousse necessary for cleaning can be accurately discharged. Further, it is possible to reduce the subsequent excessive mousse discharge request that is performed due to the lack of mousse, and it is possible to prevent the mousse from being scattered due to the excessive amount of mousse discharged.
In addition, the ON period of the mousse sensor 12 is t_TYPLonger t_MAXIn the following cases, the mousse discharge operation may be performed only during the period corresponding to the ON period. Thereby, the mousse can be discharged by an amount according to the user's request.
[0043]
Next, a seventh embodiment according to the present invention will be described with reference to FIG. FIG. 14 is a timing chart illustrating a control operation according to the seventh embodiment. The present embodiment relates to control for controlling the detection sensitivity of the drying sensor 13 to suppress a drying operation unintended by the user and thereby preventing mousse scattering.
As described above, a distance measuring sensor is used as the drying sensor 13, and the distance to the object, that is, the hand can be arbitrarily set from the drying control means 21C.
[0044]
Here, in the drying control means 21C, when the drying sensor 13 is in the OFF state, the reference distance for determining the presence or absence of the object is set to a relatively short value (SHORT), and the drying sensor 13 is once turned on. In this case, the reference distance is set to a relatively long value (LONG) during the ON period.
[0045]
As a result, when the drying sensor 13 is in the OFF state, the drying request is strictly determined, and it is possible to form a spatial margin for the user to move his / her hand for cleaning, and the drying operation unintended by the user. Can be suppressed and mousse scattering can be prevented. In addition, once the drying operation is started, even when the user moves his / her hand for drying, the drying sensor 13 is not immediately turned off, and the hand can be dried smoothly.
[0046]
Next, an eighth embodiment according to the present invention will be described with reference to FIG. FIG. 15 is a timing chart showing a control operation according to the eighth embodiment. In the present embodiment, the mousse discharged to the bowl portion 10A of the handwasher 10 is washed away by automatically performing a water discharge operation at the end of the air blowing operation to avoid clogging of the mousse.
In the case of a hand-washing device having a mousse discharge function, the mousse remaining in the mousse panel 12A or the mousse discharge port 12B may be solidified if it is not used for a long time. Some of them automatically perform an air blowing operation when necessary.
[0047]
The mousse control means 21B measures the unused time from the last mousse discharge operation, and the unused time is a predetermined time t._nWhen the time becomes (for example, 48 hours) or more, the air blowing operation is started. In this air blowing operation, only the air pump 22 is driven and the period t_brAir is pumped only (for example, around 12 seconds). Thereby, the mousse remaining in the mousse panel 12A and the mousse discharge port 12B is discharged to the bowl portion 10A.
[0048]
In the present embodiment, the water discharge operation is automatically started by the water discharge control means 21A in response to the end of the air blow operation. As a result, even when the mousse discharged to the bowl portion 10A is washed and then the drying sensor 13 is turned on by the user and the drying operation is started, no mousse remains in the bowl portion 10A. Can be avoided.
[0049]
Although the case where the water outlet 11B, the mousse water outlet 12B, and the air outlet 13B are arranged at positions facing each other in the bowl portion 10A of the handwasher 10 has been described above, the present invention is not limited thereto. Instead, the above-described embodiments can be applied to other arrangement positions, and similar effects can be obtained.
[0050]
Moreover, about each embodiment demonstrated above, you may implement individually, respectively, and may implement it combining as needed.
[0051]
【The invention's effect】
As described above, in the present invention, when a drying request is detected by the drying sensor after the mousse discharge operation, the amount of warm air blown at the start of the drying operation corresponding to the drying request is gradually increased. It is a thing. In addition to this, the drying operation corresponding to the drying request from the drying sensor is prohibited only for a predetermined prohibition period from the start of the mousse discharging operation, or the mousse corresponding to the mousse discharging request from the mousse sensor only for the predetermined prohibition period after the drying operation is completed. The discharge operation is prohibited. In addition, when a mousse discharge request is received from the mousse sensor 12 before the elapse of a predetermined period from the start of the drying operation, the drying operation is stopped and the mousse discharge operation is started.
Thereby, even when the proximity of the hand is detected almost simultaneously by both the drying sensor and the mousse sensor, the scattering of the mousse can be suppressed.
