Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wash basin having a mechanism for automatically flowing wash water to a bowl surface of a wash basin.

[0002]

2. 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 a discharge nozzle installed inside the wash basin are supplied to the wash basin. Some are equipped with a tank for storing water soap. 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.

[0005]

A washbasin with a washbasin cleaning 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, and a washbasin of the washbasin. A bowl of the washbasin in a washbasin provided inside, which is provided with a tank for storing water soap supplied to the discharge nozzle and a pump for supplying the water soap in the tank to the discharge nozzle. A basin cleaning device for supplying cleaning water to the surface, a means for accumulating the operating time of the water soap pump after the end of the operation of the basin cleaning device, and a time when the integration time of the integrating means reaches a set time. An operating means for operating the basin cleaning device is provided.

[0006]

In the wash basin of the present invention, it can be used in the same manner as an ordinary wash basin by discharging water from 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, when the amount of water soap used (the cumulative amount) in the period after the previous automatic pot washing reaches the set amount, the washing water is poured out to the pot surface to wash the pot surface. Wash automatically.

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 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.

Inside 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 (which may be 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 equipped 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.

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

In FIG. 5, when the cleaning valve 54 is closed, the routine proceeds from step 1 to step 2, the timer is reset, and the routine proceeds to step 3 to detect whether the pump 32 is operating. The user uses the water soap discharge nozzle 18
Wait in this state until you reach out to the front of
When the operation of the pump 32 is started by extending the hand 8 to the front, the process moves from step 3 to step 4 to start the timer.

After starting the timer, it is determined in step 5 whether the pump 32 is operating. If the user continues to extend his hand, the steps 5 to 6 are repeated until the timer reaches a preset time and the timer reaches a preset state. Then, the process moves from step 6 to step 7, and it is determined whether the sensor 58 detects a human body. That is, it is determined whether or not there is a human body in front of the cabinet 10. In a normal case, since the human body is standing in front of the cabinet 10 and the hand of the human body is inserted into the nozzle 18, the count of the timer is advanced and the timer is up. Therefore, the timer is up in step 6. In the step, the sensor 58 detects the human body. Therefore, the process waits at the step 7 until the human body disappears from the front of the cabinet 10. Eventually, when the human body leaves, the process moves from step 7 to step 8, the washing valve 54 is opened for a predetermined time, and the washing water is made to flow from the rim water passage 50 to the bowl surface of the washbasin 14. As a result, the pot surface is sufficiently washed. From step 8 to step 1
Then, the cleaning valve 54 is closed and the same control as described above is performed.

When the operation of the pump 32 is stopped before the timer is up in step 5 (that is, the hand is retracted from the front of the nozzle 18 before the timer is up), the process jumps from step 5 to step 9, Stop the timer and then return to step 3.

Thus, according to this control, the nozzle 1
8. The operation time of the pump 32 when the pump 32 is operated by extending the hand in front of 8 is integrated, and there is the integrated operation time after the end of the previous cleaning (that is, the integrated amount of the water discharge amount of water soap). When the amount is reached, washing water is automatically supplied and the pot surface of the washbasin 14 is washed.

In the present invention, it is preferable that a large number of water spray holes are provided in the rim water passage 50 as shown in FIG. 3 and the entire bowl surface of the washbasin 14 is washed by the flowing water. The extending direction of the water spray holes may be a crossing direction with respect to the maximum inclination direction of the bowl surface, and the wash water may swirl the bowl surface of the washbasin 14.

[0024]

As described above, in the washbasin of the present invention, the washbasin is automatically washed every time the cumulative amount of water soap used reaches the set amount. It is possible to always clean the surface.
