EXAMPLES Examples will be described below with reference to the drawings.

FIG. 1 is a perspective view of a wash basin according to an embodiment, FIG. 2 is a front view of the wash basin, and FIG. 3 is a sectional view taken along line 3-3 of FIG. FIG. 4 is a control block diagram.

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 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.

A tank 30 for storing water soap supplied to the nozzle 18 is provided in the cabinet 10. 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 and cold 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 cabinet 10 is provided with a sensor 58 for detecting the presence or absence of a human body in the front part 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 provided with the water soap supply device thus constructed, 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.

FIGS. 5 and 6 are procedure diagrams showing an automatic cleaning program for the washbasin 14. In FIGS. 5 and 6, H indicates that the sensor detects a human body, and L indicates that the sensor does not detect a human body.

FIG. 5 shows an embodiment of claim 1, wherein the water discharge stop and the human body leaving are counted as one use, and the counted number is a predetermined number n (n is 2 or more, for example, 2). (5 times), the pot surface is washed.

FIG. 6 is a time chart for explaining the second embodiment of the invention, in which the cleaning valve 54 and the cleaning valve 54 are closed even if a predetermined time elapses from the time when the water supply valve 38 or the cleaning valve 54 is closed later. If none of the water supply valves 38 is opened, the cleaning water is supplied to wet the pot surface.

By thus wetting the bowl surface, it becomes possible to prevent dirt from adhering and to clean the bowl surface.
