[Embodiment] An embodiment will be described below with reference to the drawings.

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

In FIGS. 1 and 2, a counter 12 is provided above a cabinet 10, and a washbasin 14 is provided on the counter 12.

A pop-up valve 15 is provided at the drain port 14a of the washbasin 14, and the pop-up valve is opened and closed (moved up and down) by a drive device 15A.

A back guard (vertical wall) 16 is provided on the upper surface of the back side of the washbasin 14, and a discharge nozzle (hereinafter referred to as "standing wall") for discharging water soap is provided on the front side of the back guard 16.
A nozzle 18, a water spout 20 for discharging water for face washing, hand washing, etc., and a hot air outlet 22 for drying hands are provided. In this embodiment, the supply of soap, water, and hot air is automatically started and stopped, and a lower Sensors 24, 26, and 28 are provided to detect a hand extended to the user.

A tank 30 is provided within the cabinet 10 to store the water soap supplied to the nozzle 18. This tank 30 has a configuration in which a pump 32 is attached to the side, and the pump 32 is attached to a tube 34.
It is connected to the nozzle 18 via.

A water supply valve 38 and a hot water mixing valve 40 are connected to the water spout 20 via a pipe 36, so that hot water at 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 blower outlet 22 from a hot air generator 48 via a duct 46.

The washbasin 14 has a rim passageway 50, and a water injection hole 52 (FIG. 3) of the rim passageway 50.
Cleaning water can be supplied to the bowl surface of the washbasin 14 from the washbasin 14. Wash water can be supplied to the rim water passage 50 via a wash valve 54 and piping 56. The extending direction of the water injection hole 52 is perpendicular to the direction of maximum inclination of the basin surface of the washbasin 14, and when water flows out from the water injection hole 52 into the washbasin 14, it swirls. Water swirls inside the washbasin 14.

The bag guard 16 includes a sensor 58 for detecting the presence or absence of a human body in the front part thereof, and a pop-up switch 15 for opening and closing the pop-up valve 15 at any time.
B is provided.

The detection signals of the sensors 24, 26, 28, and 58 and the signal from the pop-up switch 15B are input to a controller 60, and from the controller 60 the pump 32 is
, the water supply valve 38, the hot air generator 48, the cleaning valve 54, and the pop-up valve drive device 15A.

In the washbasin equipped with the water soap supply device configured as described above, the following control is performed according to a program stored in the computer in the controller 60. That is, when a hand is put out below the nozzle 18, the sensor 24 detects the hand, the pump 32 is activated by a 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 withdrawn, the pump 32 is stopped and the discharge of water soap is stopped. Similarly, when the hand is extended below the water spout 20 and the air outlet 22, water and hot air are blown out, and when the hand is withdrawn, the water and hot air are stopped.

FIG. 5 is a flowchart showing an automatic cleaning program for the washbasin 14.

When this happens, move from step ■ to step ■, check if there are people around, and if there are no people, immediately turn on the pop-up valve 15, and if there are people, after they leave, turn on the pop-up valve 15.
Then, the pump 32 is operated and the washing valve 54 is opened for a predetermined period of time to fill the washbasin 14 with soapy water (step 2). At this time, the water injection hole 52 intersects with the direction of maximum inclination of the washbasin 14, and the filled water forms a swirling flow within the washbasin 14, so that the dirt on the basin surface is efficiently removed.

After waiting for the required time (for example, several minutes) (step ■), the pop-up valve 15 is opened and the water is drained (steps ■, ■). After the time required for drainage (for example, 1 minute) has elapsed, the cleaning valve 54 is opened for the required time (for example, 30 seconds) to supply a predetermined amount of cleaning water to rinse the pot surface (step ■), and then Return to step ■.

As described above, according to this control, soap and washing water are automatically supplied at the required time, and the basin surface of the washbasin 14 is washed. The surface of the pot is also rinsed, making it extremely clean.

In the above embodiment, the wash water is supplied to the washbasin 14 from the wash water supply means (the wash means 54, the piping 56, the rim passageway 50, the water injection hole 52), but in the present invention, such a wash water supply means is used. may be omitted, and the bowl surface of the washbasin 14 may be washed with water discharged from the water spout 16. FIG. 6 shows a control program in that case. In this program, in step (3), the water supply valve 38 is replaced with the cleaning valve 54.
is opening the door. In addition, the process returns from step (2) to step (2) and rinsing is omitted. Other program contents are the same as the program shown in FIG.

[0028] In order to save soap by using only water to wash the pot, a mode selection switch may be provided for switching between the water washing mode and the soap washing mode.

[0029]

[Effects of the Invention] As described above, in the wash basin of the present invention, the basin surface is automatically cleaned by washing with soapy water at a predetermined time, so that the basin basin surface is always clean. It becomes possible to
