BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fully automatic basin provided with a water soap nozzle and a hot air outlet.

[0002]

2. Description of the Related Art Conventionally, a fully automatic wash basin having a water soap nozzle and a hot air vent is known, and a leakage protection breaker is provided inside a front door of a machine room disposed below the fully automatic wash basin. A technique provided with the technique was also known.

[0003]

[Problems to be Solved by the Invention] During the maintenance work of the conventional fully automatic wash basin, since the electric leakage protection breaker was not provided, an electric shock was generated when the worker inspected the electromagnetic valve and other electric circuits. Or a dangerous accident, and could not safely perform maintenance work. In addition, since the power was not controlled to be turned off when the front door was open, there was a risk of electric shock or sudden rotation of the fan motor when performing internal inspection and repair.

[0004]

The problems to be solved by the present invention are as described above. Next, means for solving the problems will be described. That is, in a fully automatic basin equipped with a water soap nozzle and a hot air outlet, a leakage protection circuit breaker for turning off the power when a leakage occurs is provided in the circuit, and an opening detection switch for detecting the opening of the front door is provided. The switch and the earth leakage protection breaker are configured to work together.

[0005]

The operation of the present invention will be described. The fully automatic wash basin shall be provided with an earth leakage protection breaker for turning off the power when an electric leakage occurs in the circuit, and an opening detection switch for detecting the opening of the front door shall be provided. Therefore, maintenance work of the fully automatic basin can be performed safely and reliably.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The problems to be solved and means to be solved of the present invention are as described above. Next, the specific structure of the present invention will be described with reference to the accompanying drawings. 1 is an overall front view of the fully automatic wash basin of the present invention, FIG. 2 is an overall side view of the fully automatic wash basin of the present invention, and FIG. 3 is a simplified perspective view of the fully automatic wash basin of the present invention with the front door opened. FIG. 4 is a flowchart of the automatic leakage control mechanism of the present invention.

The configuration of the fully automatic basin will be described with reference to FIGS. When the user places his hand on the front of the fully automatic basin 1, the human body sensor 3 disposed on the lower surface of the water outlet cover 2 of the fully automatic basin 1 detects the user's hand. At the same time, a signal is sent so that the illumination lamp 4 arranged on the lower surface of the water outlet cover 2 is turned on,
When the illuminating lamp 4 is turned on, the water soap pump 8 is activated and starts rotating, and sucks up the water soap in the water soap tank 6. At the same time, the sink 5 under the fully automatic basin 1
The electromagnetic valve 7 disposed on the side of the water soap tank 6 disposed therein is opened, and the water soap in the water soap tank 6 is sucked up by the water soap pump 8 via the water soap flow pipe 9. Then, the water soap is supplied from the water soap nozzle 10 at the tip to the hand provided by the user. When the amount of water soap in the water soap tank 6 decreases, the water soap is supplied from the water soap supply port 11 disposed on the lower surface of the water outlet cover 2 of the fully automatic basin 1 through the connection hose 12 as needed.

When the user who has washed his / her hands with the water soap moves his / her hand to the water outlet 13, a human body detection sensor disposed on the lower surface of the water outlet cover 2 as in the case of supplying water soap. At the same time as the user 3 detects the hand of the user, a signal is sent so that the illumination lamp 4 disposed on the lower surface of the water outlet cover 2 is turned on. Electromagnetic valve 7 arranged on the side of the water soap tank 6 arranged in the washstand 5
Is opened, and hot water adjusted to an appropriate temperature by the mixing thermostat 14 disposed below the electromagnetic valve 7 passes through the hot water distribution pipe 16 via the mixing faucet 15 and is sent out from the water outlet 13 by the user. Sufficient water is supplied to the hand, and the sewage washed away by the warm water is discharged through a drain port provided in the lower central portion of the fully automatic basin 1.
It is discharged from 7.

Next, when the washed hand is moved to the hot air outlet 18, the human body sensor 3 disposed on the lower surface of the water outlet cover 2 detects the user's hand as in the case of supplying water soap. At the same time, a signal is sent so that the illuminating lamp 4 disposed on the lower surface of the water outlet cover 2 is turned on. When the illuminating lamp 4 is turned on, the illuminating lamp 4 is placed in the wash basin storage 5 below the fully automatic basin 1. The warm air fan 19 is started and warm air blows out from the warm air port 18 through the warm air heater 20 and the warm air duct 21 to dry wet hands.

The human body detecting sensor 3 is composed of an infrared sensor, an ultrasonic sensor, and the like, and a signal is continuously transmitted from the transmitting device to the receiving device, and is turned on so that the user's hand can be always sensed. On the other hand, the illumination lamp 4 is turned off in the OFF state when there is no user, but the signal from the transmitter of the human body sensor 3 to the receiver is cut off by the user's hand. Then, the user's hand is sensed as an obstacle that blocks the infrared sensor, the ultrasonic sensor, and the like, and at the same time, another signal is sent from the human body detection sensor 3 to the illumination lamp 4 so as to be turned on. The illuminating lamp 4 is to be turned on, and the human body sensor 3 and the illuminating lamp 4 are independently installed near the water soap nozzle 10, the water outlet 13 and the hot air outlet 18 to start. It is what is configured.

Next, the automatic leakage control mechanism of the present invention will be described with reference to the flow charts of FIGS. First, the automatic leakage control mechanism of the present invention is turned on. Next, as shown in FIG. 4, when the front door 5a of the sink 5 is opened at the time of maintenance work such as replenishment of water soap or repair of an electric circuit, the opening detection switch 22 immediately detects this and turns on.
A signal is sent to the earth leakage protection breaker 23 that is linked in the state, and the earth leakage protection breaker 23 receives the signal and stops energization of the earth leakage protection breaker 23,
In addition, even when a leakage occurs in a part of the electric circuit other than during maintenance work such as replenishing water soap or repairing the electric circuit as described above, the leakage protection breaker 23 of the present invention operates alone. The energization is stopped.

A bracket 24 supports the fully automatic wash basin 1 on both sides of the wash basin storage 5.
And the sink 5 is provided with four legs 25 and floor fixing bolts 26.
It is fixed to the floor.

[Effect of the Invention] The present invention is constructed as described above, and has the following effects. That is, a dangerous accident such as an electric shock due to electric leakage is prevented during the maintenance work of the fully automatic basin, and the maintenance work can be performed safely and reliably. In addition, when water soap is lost in the tank, it is necessary for maintenance personnel to make up for this, but at this time, while opening the front door and working, electrical leakage occurred. There was a risk of electric shock. Also, while working, the short circuit of the circuit may cause the soapy water pump and the motor for driving the hot air fan to start rotating, resulting in personal injury. Was eliminated.
