Description

[Detailed Description of the Invention] <Industrial Field of Application> The present invention relates to a handwash installed in workplaces such as the electronics industry and the food industry, and more specifically, in clean rooms.

<Prior Art> Conventionally, as shown in Figure 4, this type of clean room has been equipped with gratings, punched metal, etc. on the floor, and has a large number of exhaust air intake ports 10.
1 is opened, indoor air is sucked in from the exhaust intake port 101 by a fan 102 installed outdoors, and is circulated indoors via an air filter 103 installed on the ceiling, thereby removing dirt and dust from entering the room. Prevents accumulation or accumulation.

However, since the washbasin 104 installed in this clean room is installed so as to protrude from the wall surface 105, the circulating airflow above and below the washbasin 104, specifically the downflow from the ceiling, is disturbed and stagnation airflow occurs. If this air contains dirt, dust, etc., it will stay there forever, especially on the top surface of the washbasin 104, and there is a risk that this will be scattered again.

<Problem to be solved by the invention> The problem to be solved by the invention is to prevent dirt and dust from accumulating, accumulating, and re-dispersing without disturbing the circulating air flow in the clean room.

<Means for solving the problem> The technical means taken by the present invention to solve the above problem is to open an opening facing the bowl part at the upper front of the washbasin body, and to open this opening into the room. The washbasin body is installed in a semi-embedded or embedded manner, and at least the upper edge of the opening is substantially flush with the wall surface.

<Function> The present invention reduces air resistance against downflow by reducing the amount of protrusion of the washbasin body from the wall surface.

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

As shown in FIG. 1, this embodiment shows a case in which a washbasin main body A is placed on a pedestal C and attached to a wall surface B in a semi-embedded manner.

The washbasin main body A is made of ceramic or synthetic resin, and includes a bowl part a1 formed in a substantially mortar shape, a covering part a2 that covers the upper surface of the bowl part a1, and a bowl part a.
1 is integrally provided with an exhaust passage a3 formed at the lower end.

The bowl part a1 has a rim water passage a4 formed in an annular shape around the entire circumference at its upper edge, and a dome-shaped covering part a2 is provided along the upper surface of the rear half of the rim water passage a4, thereby creating a washbasin. An opening a5 is opened at the upper front surface of the main body A.

Further, the washbasin main body A has an annular locking step part a6 vertically protruding from the front edge of the cover part a2 to the outer peripheral surface of the bowl part a1, and the locking step part a6 is attached to the wall surface. Fit into the peripheral edge of the mounting hole b1 opened in B.

Therefore, when the handwash main body A is installed, the opening a
5 The upper edge is substantially flush with the wall surface B, and the bowl part a1
Only the front end protrudes from wall surface B.

A water inlet a7 to which the water supply pipe 2 communicating with the solenoid valve 1 is connected is provided on the back side of the rim water passage a4, and a large number of water injection holes a8 are bored at appropriate intervals on the lower surface. Cleaning water supplied from the electromagnetic valve 1 is discharged from water injection holes a8 along the inner surface of the bowl portion a1 to form a water film for cleaning.

Further, a drain port a9 to which the drain pipe 3 is connected is provided at the bottom of the bowl portion a1, and the diameter of the drain port a9 is such that even when the largest amount of washing water is spouted from the water spouting tool 4, which will be described later, the bowl portion a1 The exhaust passage A3 is designed to have a size that prevents water from accumulating at the bottom of the exhaust passage A3, and the entrance of the exhaust passage A3 is established on a side surface higher than the drain port A9, which is the rear side surface in the drawing.

The exhaust passage a3 extends obliquely upward from the inlet along the back surface of the bowl part a1, and has an exhaust pipe 5 connected to the outside connected to its tip, and an exhaust fan 6 is disposed in the middle of the exhaust pipe 5.

The exhaust fan 6 rotates to open the exhaust path a3.
The air in the bowl part a1 is transferred from the inlet of the bowl part a1 to the bowl part a1.
The system makes a U-turn at the bottom to suck in the air and exhaust it outside through an exhaust pipe 5. In this embodiment, its operation is controlled by a sensor 7, which will be described later, so that the air volume changes after a predetermined period of time from the start of operation. I have to.

That is, while the exhaust fan 6 is discharging cleaning water from the water discharging device 4, which will be described later, the number of revolutions of the exhaust fan 6 is low, and when hot air is blown out from the outlet 8, which will be described later, the number of revolutions increases, so that the amount of suction is increased. It's summery.

On the other hand, the covering part a2 includes a water spouting tool 4 for washing the user's hands, and a spout 8 for drying the hands after washing.
Sensors 7 for controlling the operations of both are provided in a penetrating manner.

The water discharging device 4 is connected to its upper end with a water discharging pipe 9 branched from the secondary side of the electromagnetic valve 1 that supplies wash water to the rim water passage a4, and is installed so that its lower end protrudes inward to the cover portion a2. This prevents splashes of wash water supplied from the solenoid valve 1 from scattering outside the washbasin main body A.

A ventilation pipe 10 is connected to the air outlet 8, and the ventilation pipe 1
A blower fan 11 that blows out indoor or outdoor air at high speed is provided in the middle of the
1, an air filter 13 consisting of a heater 12 and a sterilization filter that removes dirt and dust in the air and oxides scattered from the surface of the heater 12.
and will be deployed sequentially.

The sensor 7 is a conventionally well-known photoelectric sensor, and sends a sensing signal to the controller 14 when the user inserts his or her hand into the bowl portion a1 through the opening a5.

The controller 14 includes the solenoid valve 1, the exhaust fan 6, the sensor 7, the blower fan 11, and the heater 12.
are electrically connected to each other, and when a sensing signal is sent from the sensor 7, the solenoid valve 1 is opened for, for example, 10 to 15 seconds, and the exhaust fan 6 is rotated at a low rotation speed, and then, for example, Heater 1 for seconds to 1 minute
2 to generate heat and rotate the blower fan 11,
Furthermore, the exhaust fan 6 is rotated at a high rotation speed.

When the user inserts his or her hand into the bowl part a1 through the opening a5, the wash water is spewed out from the water injection holes a8 of the rim passageway a4 to form a water film on the inner surface of the bowl part a1. At the same time, water is sprayed from the water spouting device 4 in a shower shape to wash the user's hands, and furthermore, the air in the bowl portion a1 is exhausted from the exhaust path a3. At the same time as these operations stop, the air outlet 8
By blowing out hot air at high speed, the water droplets on the hands are blown away and dried, and the amount of suction from the exhaust passage A3 is increased to suck up dirt and dust generated from the user and their clothes while washing their hands. exhaust to.

In the above-mentioned embodiment, the washbasin main body A was placed on the pedestal C and attached in a semi-recessed manner from the back side of the wall B, but the present invention is not limited to this. The exhaust fan 6 may be completely recessed and installed, and although the air volume of the exhaust fan 6 is changed after a predetermined period of time, the exhaust fan 6 rotates at the same time as hot air is blown out from the air outlet 8 without changing the air volume. You can do it like this.

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

Since the amount of protrusion of the washbasin body from the wall surface is reduced, air resistance to downflow can be reduced, and unlike conventional models, downflow is disturbed and airflow stagnates above and below the washbasin body. With nothing to do,
The upper edge of the opening at the top of the front of the washbasin body is formed almost flush with the wall surface, so there is no flat surface that protrudes into the clean room like in conventional models, where dirt and dust can accumulate. Never.

Therefore, the circulating air flow in the clean room is not disturbed, and dirt, dust, etc. can be prevented from accumulating, accumulating, and being re-dispersed.
