Description

[Detailed description of the invention] <Industrial application field> The present invention relates to a hand wash installed in workplaces (clean rooms) in the electronics industry and food industry, operating rooms in hospitals, etc.

<Prior art> Conventionally, as this type of handwash, for example,
As disclosed in Publication No. 101169, a water spouting device and a drying air outlet are provided, and by automatically discharging washing water and then blowing out warm air, it is possible to wash and dry hands without touching anything. There are devices designed to prevent microscopic dust and bacteria from people's hands and fingers from being brought into the room.

<Problems to be solved by the invention> However, with these conventional hand wash basins, when hot air is blown out, dust adhering to the bowl surface of the wash basin and skin aging substances generated by rubbing hands together are mainly removed. There is a problem in that dust such as these is diffused into the room along with the warm air.

In addition, a large amount of fine dust is generated due to the vibration of clothes or rubbing of cuffs during hand washing, and these dust can re-adhere to hands and clothes.
There is also the problem of it being scattered indoors.

Therefore, it is possible to create an exhaust port in the wash basin and use an exhaust fan to exhaust the dust generated during drying outside, but if the exhaust port is installed near the top edge of the bowl, warm air will be blown into the bowl. There is a risk that the hot air that has made a U-turn at the bottom of the bowl will collide with the airflow and cause the airflow to flow out of the bowl.To prevent this, if the outlet is opened near the bottom of the bowl, the cleaning water remaining during cleaning will flow into the exhaust port. There is a problem that the particles may penetrate and cause the exhaust fan to malfunction or deteriorate the exhaust performance.

In view of the conventional situation, the present invention aims to exhaust all the drying air blown into the bowl without blowing in washing water.

<Means for Solving the Problems> The technical means taken by the present invention to solve the above problems is to open a drainage hole in the bottom of a bowl shaped like a mortar, and install an exhaust fan on the side higher than the drainage hole. An exhaust port that communicates with the outside through the bowl is opened toward the bottom of the bowl, and a guide wall that guides the washing water flowing down above the exhaust port to the drain port is provided so as to protrude diagonally downward toward the center of the bowl. This device is characterized in that an air outlet for blowing out drying air is arranged from the bowl inlet, through the bowl bottom, and toward the exhaust port.

<Function> According to the technical means of the present invention, the drying air blown out from the outlet flows down from the bowl inlet along the inner surface of the bowl, makes a U-turn at the bottom of the bowl, is sucked through the exhaust outlet, and is exhausted to the outside. It is something that makes you

<Example> Hereinafter, an example of the present invention will be described based on the drawings.

In this embodiment, as shown in FIG. 1, a wash basin A is placed on a cabinet G and attached along a wall surface H.

Wash basin A is made of ceramics and synthetic resin,
A bowl a1 is formed inside it.

The bowl a1 is formed into a gentle mortar shape so that the washing water from the water spouting devices C installed above the washbasin A does not scatter outside the bowl, and the drying air from the outlet D hits the surface of the bowl a1. The height of the front edge is set to be, for example, about 750 to 1000 mm, so that the user can insert his or her hand close to the elbow without bending the waist. In addition, a drain port a2 is provided at the bottom of the bowl a1 to connect the drain pipe 1,
An exhaust port a3 is provided on a side surface higher than the drain port a2, which is a rear side surface in the drawing.

The drain port a2 is formed to have a diameter that prevents water from accumulating at the bottom of the bowl a1 even when the largest amount of washing water is spouted from the water spouting tool C.

An exhaust pipe b1 communicating with the outside is connected to the exhaust port a3, an exhaust fan B is disposed in the middle of the exhaust pipe b1, and a guide wall a4 is provided vertically above the port a3.

The guide wall a4 protrudes diagonally downward from the rear side of the bowl a1 toward the center of the bowl a1, and has its tip hanging down to a position that covers at least the upper half of the exhaust port a3, thereby directing air from the exhaust port a3. Even if the cleaning water is sucked, the washing water flowing down along the guide wall a4 does not enter the exhaust port a3 and is guided to the drain port a2.

The exhaust fan B opens the exhaust port a3 by its rotation.
The air near the inlet of bowl a1 passes between the front surface of bowl a1 and the guide wall a4, and
Make a U-turn at the bottom of 1 to suck it up and then connect it to the exhaust pipe b1
In this embodiment, the operation is controlled by a photoelectric sensor E installed above the washbasin A.
The airflow rate is controlled by the airflow control system so that the air volume changes after a predetermined period of time from the start of operation.

That is, the exhaust fan B starts operating when the user approaches the wash basin A, but the rotation speed of the exhaust fan B is low while flushing water is being discharged from the water spouting tool C, which will be described later, and the water spouting tool stops operating after a predetermined period of time. When the water spout from C is stopped, the rotation speed increases and the amount of suction is increased to suck out the dust generated from the user and his/her clothes while washing hands, and when the user leaves, the exhaust fan B is stopped after a certain period of time. There is.

In addition, a rim water passage a5 is formed in the upper edge of the bowl a1 with a number of water injection holes a6... bored in the lower surface, and a water supply chamber a7 is provided in a continuous manner projecting from the rear end of the rim water passage a5. The above photoelectric sensor E is installed in room a7.
A water discharge pipe f1 is connected to an electromagnetic flush valve F arranged in the case e1, and the cleaning water supplied from the electromagnetic flush valve F is discharged from the water injection holes a6 along the inner surface of the bowl a1, Forms a water film and washes.

On the other hand, above the wash basin A, the water spouting device C and the drying air outlet D are provided respectively toward the bowl a1, but in this embodiment, both are provided on the lower surface of the case e1 of the photoelectric sensor E.

The water spouting tool C is connected to the electromagnetic flush valve F to spray water toward the center of the bowl a1 to wash the user's hands, and is installed on the bottom surface of the case e1 so as to protrude downward. , to prevent splashes of washing water from scattering outside the device.

The drying air outlet D blows clean indoor air sucked in by a fan (not shown) toward the center of the bowl a1 at high speed, thereby blowing off water droplets on the user's hands and drying the hands with the airflow. It is intended to promote

It is also possible to install a heater inside the outlet D to accelerate drying with hot air, but if a heater is used, oxides may scatter from the surface of the heater, so if necessary, air filtration should be carried out before the outlet D. Set up a container.

The photoelectric sensor E also controls the operation of the electromagnetic flush valve F that supplies water to the rim passageway a5 and the water discharging device C, and the fan that blows out drying air from the outlet D.

That is, when the user approaches the wash basin A, water is supplied to the rim passageway a5, washing water is discharged from the water spouting device C, and after a predetermined period of time, the water supply to these is stopped and a fan is rotated to blow out drying air. The system is designed to stop when the user leaves the wash basin A.

Incidentally, in the previous embodiment, the wash basin A was placed on the cabinet G and installed along the wall surface H.
The handwash A may be directly attached to the wall H without being limited to this, and although the exhaust fan B is configured to change the air volume after a predetermined time, drying air is blown out from the outlet D without changing the air volume. The exhaust fan B may be rotated at the same time.

<Effects of the Invention> Since the present invention has the above configuration, it has the following advantages.

The drying air blown out from the outlet flows down from the bowl inlet along the inner surface of the bowl, makes a U-turn at the bottom of the bowl, is sucked in through the exhaust port, and is exhausted outside, so it is blown into the bowl without blowing in cleaning water. All drying air can be exhausted.

Therefore, the dust generated during drying can be reliably discharged, the dust adhering to the bowl surface and skin aging substances generated by rubbing hands together will not be diffused into the room, and moreover, the cleaning water will not flow into the exhaust port. There is no infiltration, and there is no malfunction of the exhaust fan or deterioration of exhaust performance.
