Description of the Related Art As a wash basin, a wash basin, a spout and a water soap discharge nozzle provided at the rear or side of the wash basin, and water is automatically discharged when a hand is put out to the spout. Some of them include a control device for turning on and a tank for storing water soap supplied to the discharge nozzle, which is installed inside the wash basin. The wash basin may be provided with a hot air outlet for hand washing and drying.

The water soap stored in this tank is usually sent to a discharge nozzle by a pump.

[0004]

With the basin, dirt adheres to the bowl surface of the basin as it is used. In offices, etc., the cleaning staff regularly cleans this pot surface, but if this cleaning is infrequent, it will be left dirty and uncomfortable for the user. Will be things. In particular, when the hands are washed with water soap, not only the dirt component but also the soap component adheres to the pot surface, and the stain on the pot surface is easily increased.

[0005]

A method of controlling washing of a washbasin equipped with a washbasin washing device according to the present invention comprises a washbasin, a spout and a water soap discharge nozzle provided at the rear or side of the washbasin. An automatic water discharge means for detecting water discharged from the hand out to the water discharge port, a tank for storing water soap supplied to the discharge nozzle, which is installed inside the wash basin, and the inside of the tank In the washing control method of the wash basin, the pump for supplying the water soap to the discharge nozzle, and a washbasin cleaning device for supplying the wash water to the bowl surface of the washbasin, the water soap discharge by the pump. Detecting the amount and the amount of water spouted by the subsequent automatic water spouting operation, comparing the standard wash water amount preset with the automatic water spouting amount by the automatic water spouting operation to increase in proportion to the discharge amount of water soap, The automatic water discharge is below the standard wash water If that is characterized in that operating the basin cleaning device to supply substantially the same amount of wash water and the difference between the two pots surface.

[0006]

In the wash basin of the present invention, it can be used in the same manner as a normal wash basin by ejecting water by ejecting a hand to the water outlet or discharging water soap from the nozzle.

With this use, dirt adheres to the bowl surface of the washbasin. This stain adhesion is almost proportional to the amount of water soap used. That is, as the amount of water soap used increases, the amount of soap components and the amount of stain components washed off from the hands with soap increase, and the pot surface becomes dirty.

Therefore, in the present invention, in a series of hand washing operations of discharging water soap and subsequently discharging water (washout of soap from the hand), the standard amount of wash water is increased so as to increase in proportion to the amount of water soap used. Set it. When the actual automatic water discharge amount is less than the reference amount of wash water, the wash water is supplied to the bowl surface in an amount substantially equal to the difference between the two to wash the washbasin.

As described above, the wash basin can be kept clean by supplementing and flushing the wash water as needed.

In FIGS. 1 and 2, a counter 12 is provided on the upper side of the cabinet 10 and a washbasin 14 is provided on the counter 12. A back guard (standing wall) 16 is erected on the back side upper surface of the washbasin 14, and a discharge nozzle (hereinafter, abbreviated as a nozzle) 18 for discharging water soap is provided on the front side of the back guard 16. A spout 20 for discharging water for face washing, hand washing, etc., and a hot air outlet 22 for drying the hand are provided. In this embodiment, the supply of water soap, water, and hot air are automatically started and stopped, respectively.
8, near the spout 20 and the outlet 22, sensors 24, 2 for detecting the hand extended downward.
6, 28 are provided.

In the cabinet 10, a tank 30 for storing water soap supplied to the nozzle 18 is provided. The tank 30 has a structure in which a pump 32 is attached to a side surface, and the pump 32 is a tube 34.
It is connected to the nozzle 18 via.

The water discharge port 20 is connected to a water supply valve 38 and a hot water mixing valve 40 via a pipe 36 so that hot water of a predetermined temperature can be supplied. 42 is a water supply pipe and 44 is a hot water supply pipe. Warm air can be supplied to the air outlet 22 from a warm air generator 48 via a duct 46.

The washbasin 14 has a rim water passage 50, and a water spray hole 52 (FIG. 3) of the rim water passage 50.
The cleaning water can be supplied to the bowl surface of the washbasin 14 from the above. Cleaning water can be supplied to the rim water passage 50 through a cleaning valve 54 and a pipe 56.

The bag guard 16 is provided with a sensor 58 for detecting the presence or absence of a human body in the front portion thereof.

The detection signals of the sensors 24, 26, 28, 58 are input to the controller 60, and the controller 60 pumps the pump 32, the water supply valve 38, the hot air generator 48, and the cleaning valve 5.
The control signal is output to 4.

In the wash basin equipped with the water soap supply device thus configured, the following control is performed according to the program stored in the computer in the controller 60.
That is, when a hand is extended to the lower side of the nozzle 18, the sensor 24 detects this hand, the pump 32 is operated by the signal from the controller, and the water soap in the tank 30 is supplied to the nozzle 18, It is discharged from the tip of 18. When the hand is retracted, the pump 32 is stopped and the discharge of water soap is stopped. Similarly, when the hand is extended below the water discharge port 20 and the air outlet 22, water discharge and warm air blowing are performed, and when the hand is retracted, water stop and warm air stop are performed.

After washing the hand with water soap, water is poured into the hand to rinse the hand. The water discharge amount (integrated amount) at this time is determined by the opening time of the water supply valve 38. Ask.
(Note that a flow meter may be provided to directly obtain the actual water discharge amount.) Next, this actual water discharge amount is compared with the reference cleaning water amount. This reference amount of cleaning water is preset so as to increase in proportion to the discharge amount of water soap as shown in FIG. In FIG. 5, the amount of water soap and the amount of standard cleaning water are directly proportional. In FIG. 5, the amount of standard washing water is made to be directly proportional to the amount of water soap up to the middle, and the amount is capped to a certain degree or more to save water.

## EQU2 ## is such that both have a curved correlation. Although not shown, the correlation may be a curve that is convex downward, contrary to FIG.

The standard washing water amount is obtained from the relationship set as shown in FIG. 5, and if it is less than the actual water discharge amount, the washing valve 54 is opened for a predetermined time, and an amount of washing water substantially equal to the difference between the two is applied to the pot surface. Pour into. With this, when a large amount of water soap is used, sufficient water corresponding to this is supplied to the bowl surface,
Soap and dirt components are sufficiently removed and the pot surface is always kept clean.

In this embodiment, when the sensor 58 no longer detects the human body, that is, after the human body leaves the cabinet 10, the insufficient cleaning water is made to flow out. In this way, the water does not unexpectedly leak and surprise the user.
