■ The user can freely select the functions of water spouting, hot air blowing, and water soap discharging, and can operate them for the desired amount of time while washing their hands, so no matter how you use it, there will be no wasted operation. .

■ Since the water spout, hot air outlet, water soap discharge nozzle, and each sensor are installed in the washbasin, the area around where they are installed can be neatly grouped together. It can be easily and reliably cleaned in one place and kept clean at all times.

(Example) Hereinafter, one embodiment of the present invention will be described based on the drawings.

(A) shown in FIGS. 1 to 3 is a hand washing device that has both a water spouting function and an air blowing function.

The handwashing device (A) has a handwashing basin (1) installed inside an opening (3a) opened on the top surface of the counter (3).
A water soap discharge nozzle (a) and a water spout (b) are placed around the ball part (1a) of 1) in a place facing the user.
m air outlets (C) are installed at appropriate intervals in the lateral direction.

The discharge nozzle (a), water spout (b), and air outlet (c) are fitted into the mounting ports (4a), (4b), and (4c) provided in the washbasin (1) from the front side, respectively, and the fixing ring ( a+
)(t)+ )(C+) are screwed together and fixed to the wash basin (1). In addition, right below the discharge nozzle (a), water spout (b), and air outlet (C) in the handwash basin (1), there is a photoelectric sensor (2aH2b) that detects the user's hand.
(2c) is provided respectively.

The above-mentioned discharge nozzle (a), water spout (b), and air outlet (C) are installed around the ball part (1a) of the washbasin (1), so the area around these mounting parts is shown in the first factor. It can be organized neatly and with plenty of time. Each sensor (2a) (2bH
2c) is equipped with a light emitter and a light receiver, and the light emitter always emits light in the direction shown in Figure 3, and this light is projected in front of these sensors (2a) (2bH2c). It hits your hand and reflects. Sensor (2aH2b) (2c
) detects the user's hand by receiving this reflected light with the light receiving section, and when the user's hand is detected,
A sensing signal is sent to a control section (d) that activates and stops each functional section, which will be described later.

A frame (6a) is assembled at the lower part of the counter (3), and the frame (6a) is covered with a decorative board (6b) to form a storage section (6). Ball part (
In addition to installing the drain pipe (5) in 1a), the water outlet (b)
Drought mixer tap (7) that sends dry water to.

A hot air fan (8) that sends air to the solenoid valve (10) and the air outlet (C)
) and an electromagnetic pump (9) that sends water soap to the water soap discharge nozzle (a), and other functional units are internally installed.

The electromagnetic pump (9) communicates with a sensor (2a) provided under the discharge nozzle (a) via a control part (d), and is activated when this sensor (2a) detects the hand extended by the user. Then, the water soap stored in the water soap tank (11) is passed through the communication pipe (12) to the discharge nozzle (a).
).

The water soap in the water soap tank (9) is placed in the hand wash basin (1
) is refilled from the replenishment port (13) provided on the front side.

The turbid water mixing faucet (7) mixes water and lagoon supplied from a water supply pipe and a hot water supply pipe (not shown) to a desired temperature by adjusting the handle (7a). This drought mixer faucet (7)
The mixed water and water are supplied to the water spout (b) via a solenoid valve (10) provided in the middle of the water supply pipe and the pipe (14).

The solenoid valve (10) communicates with the sensor (2b) under the spout (b) via the control part (d), and the sensor (2b)
) senses the user's hand, the valve opens and the lagoon or water is spouted from the spout (b).

Warm F [(8) is the one that heats the air taken in from the suction port (8a) with the heater (8b) to form hot air, which is passed through the air pipe (15) and blown to the air outlet (C). and the sensor (2C) under the air outlet (C) and the control part (d)
When the sensor (2C) detects the user's hand, it is activated and blows out [a] from the air outlet (C).

As mentioned above, each function of water soap discharge, water discharge, and warm water discharge is controlled by the sensor (2aH2b) installed in hand wash 15(1).
) and (2c) operate independently by sensing the hand held out immediately before, and stop operating when the user withdraws the hand and the sensing is cut off.

Note that the sensors (2aH2b) (2c) are not limited to photoelectric sensors; for example, capacitance sensors may be used, or
Alternatively, a charge sensor and a capacitance ω sensor may be used together.

Next, the basic operation of the hand washing device (A) having the above configuration will be explained based on the time chart shown in FIG. 4.

Each sensor (2a) (2b) (2c)
It recognizes a sensing state when it is sensed for more than one hour, and cancels sensing for more than T+ time to prevent each function from operating indiscriminately. In addition, in the sensing state, it is recognized that the state is converted to a non-sensing state when the same sensing for T411 or more ends, and even if the sensing for a time shorter than that ends, the sensing continues. It is designed to prevent the operation from stopping unexpectedly.

Therefore, when the user extends his hand to the water soap discharge nozzle (a) and the sensor (2a) detects this for more than T1 time, the electromagnetic pump (9) intermittently fires at intervals of TaF5 for 12 hours. The water soap is discharged from the discharge nozzle (a). Then, if the hand covered with water soap is removed from in front of the sensor (2a) and the non-sensing state continues for 14 hours or more, the electromagnetic pump (9) will stop.

After washing your hands with soap, if you put your hand out to the water spout (1) and the sensor (2b) detects this for more than T+ time, the solenoid valve (10) opens and the water drain mixer (1) is opened from the water spout (b). The lagoon or water at the desired temperature mixed in step 7) is discharged.

When you move your hands to the warm air outlet (b) after washing your hands with water from the water spout (b), the solenoid valve (10) will open after 14 hours to stop the water spout, and the sensor ( 2C) senses the user's hand and after T1 hours, the warm air fan (7) is activated and hot air is blown out from the air outlet (C).

After drying the hands with hot air, the hands are removed from the air outlet (C) and if the non-sensing state continues for 14 hours or more, the hot air fan (8) stops.

As mentioned above, the hand washing device (A) has water spouting, hot air blowing,
The user can arbitrarily select each 81M capacity of water soap discharge,
Since the user can wash his hands while operating the device for a desired time, there will be no wasted operation, no matter what process the user uses to wash his hands.

In addition, the discharge nozzle (a), the water outlet (b), the outlet (C)
are installed on the circumference of the ball part (1a) of the handwash basin (1), so the area around these mounting parts can be neatly gathered together, and therefore the area around the mounting parts of each of the above equipment can be placed around the handwash basin (1) and the - place. It can be easily and reliably cleaned and kept clean at all times.

Furthermore, a discharge nozzle (a) and a water spout (b).

Since the three air outlets (C) are arranged side by side at appropriate intervals around the circumference of the ball part (1a), it is very easy to use as it allows you to apply soap, wash your hands, and dry them naturally. You can wash your hands well and efficiently.

Note that the hand washing device of the present invention may be configured not only for hand washing but also for washing.
