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.

<Conventional technology> Conventionally, this type of clean room has been constructed by laying gratings, punched metal, etc. on the floor surface, opening a number of exhaust intake ports, and sucking room air from the exhaust intake ports with a fan. By circulating air into the room through an air filter installed on the ceiling, dirt and dust are prevented from accumulating or accumulating inside the room.

However, since the hand wash basin installed in this clean room washes hands with the washing water that flows from the water spout inside the bowl, droplets of dirty water are scattered on the inside of the bowl, and moreover, this dirty water is washed away by the washing water from the water spout. Often there isn't.

Therefore, there is a problem in that when the dirty water adhering to the inner surface of the bowl portion dries after use, it becomes dust and scatters indoors.

<Problem to be solved by the invention> The problem to be solved by the invention is to completely wash away the waste water scattered on the inner surface of the bowl part.

<Means for Solving the Problems> The technical measures taken by the present invention to solve the above problems include branching the secondary side of the water supply device and cleaning the upper edge of the bowl portion toward its inner surface. A rim water passage with a number of water injection holes for discharging water is provided, one of which is connected to the rim water passage, and the other branch is connected to a water spout for hand washing provided above the bowl. be.

<Function> The present invention cleans the inner surface of the bowl portion by discharging cleaning water from the water supply device through the water injection hole of the rim passageway at the same time as the water discharging tool.

<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 handwash main body A is provided with a hot air outlet 6 for drying hands after washing and an exhaust passage a ₃ for discharging this hot air to the outside. .

The washbasin main body A is made of ceramic or synthetic resin, and includes a bowl part _a1 formed into a substantially mortar shape, a covering part _a2 that covers the top surface of the bowl part _a1 , and a bottom end of the bowl part _A1 . It is integrated with exhaust path _A3 .

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 . Accordingly, an opening _a5 is opened at the upper front of the washbasin main body A.

A water supply port _A6 to which a water supply pipe 2 communicating with the water supply device 1 is connected is opened on the back side of the rim water passage _A4 ,
A large number of water injection holes _a7 ... are drilled at appropriate intervals on the lower surface, and the washing water supplied from the water supply device 1 is discharged from the water injection holes _a7 ... along the inner surface of the bowl part _a1 . It is designed to form a film for cleaning.

The water supply device 1 supplies washing water from a water supply source to the handwash body A, and in this embodiment, the sensor 3
This shows a solenoid valve that opens and closes with a water supply pipe 2 that connects the secondary side, that is, the outlet of the solenoid valve, to the rim water passage _A4 .
A water spouting pipe 5 is provided which branches off from the middle of the water supply pipe 2 and connects to a water spouting device 4.

The water discharging device 4 is disposed penetratingly through the covering part a ₂ together with the sensor 3 and the outlet 6 described later, and has a water discharging pipe 5 connected to its upper end, and has a lower end connected to the covering part a _{2 .}
By attaching it so as to protrude inward, splashes of washing water supplied from the water supply device 1 are prevented from scattering outside the washbasin main body A.

In addition, a drain port _a8 to which the drain pipe 7 is connected is provided at the bottom of the bowl portion _a1 , and the diameter of the drain port _a8 can be adjusted even when the largest amount of washing water is spouted from the water spouting device 4, which will be described later. The bottom of bowl part A ₁ should be sized so that water does not accumulate, and the side surface higher than this drain port A ₈ should be
In the drawing, the entrance of exhaust passage _A3 is opened on the rear side.

The exhaust path _A3 extends obliquely upward from the inlet along the back surface of the bowl portion _A1 , and has an exhaust pipe 8 connected to the outside connected to its tip, and an exhaust fan 9 is provided in the middle of the exhaust pipe 8. .

The exhaust fan 9 sucks the air in the bowl _part A 1 from the entrance of the exhaust passage A ₃ through the bottom of the bowl part A ₁ by rotating it, and exhausts it to the outside through the exhaust pipe 8. In this embodiment, the operation is controlled by the sensor 3, and the air volume is changed after a predetermined time from the start of the operation.

That is, the rotation speed of the exhaust fan 9 is low while discharging cleaning water from the water discharging device 4, which will be described later, and increases in rotation speed when blowing hot air from the air outlet 6, which will be described later, to increase the amount of suction. It's summery.

A ventilation pipe 10 is connected to the air outlet 6, 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 3 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 water supply device 1, the sensor 3, the exhaust fan 9, the ventilation fan 11, and the heater 1.
2 are electrically connected to each other, and the above sensor 3
When a detection signal is sent from the system, the water supply device 1 is opened for, for example, 10 to 15 seconds, the exhaust fan 9 is rotated at a low rotation speed, and then the heater 12 is energized for, for example, 30 seconds to 1 minute to generate heat and blow air. The fan 11 is rotated, and the exhaust fan 9 is further rotated at a high rotation speed.

Therefore, 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 hole _A7 of _{the rim passageway A4 ,} and the water is discharged into the bowl part _A1. A water film is formed on the inner surface, water is sprayed from the water spouting device 4 in a shower shape to wash the user's hands, and the air in the bowl portion _a1 is further exhausted from the exhaust path _a3 . At the same time as these operations stop, hot air is blown out at high speed from the air outlet 6 to blow away water droplets on the hands and dry them, and the amount of suction from the exhaust passage _A3 increases, causing the user to wash their hands and their clothes. It sucks up dirt and dust generated from the air and exhausts it outside.

In the above-mentioned embodiment, the water supply device 1 is a solenoid valve that is opened and closed by the sensor 3, but the solenoid valve is not limited to this, and the solenoid valve may be opened and closed by a manual switch. An electromagnetic flash valve may also be used.

In addition, although the air outlet 6 and the exhaust passage a ₃ are provided in the washbasin body A, it is not necessary to provide them, and the exhaust fan 9 is also provided.
Although the air volume is changed after a predetermined time, the exhaust fan 6 may be rotated at the same time as the hot air is blown out from the air outlet 8 without changing the air volume.

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

Since the washing water from the water supply device is sprayed from the water injection hole in the rim passageway at the same time as the handwashing water spouting device to wash the inner surface of the bowl, even if droplets of dirty water are splashed on the inner surface of the bowl during hand washing, they are completely washed away. This prevents dirty water from remaining on the inner surface of the bowl.

Therefore, the waste water does not dry out and become dusty and scatter as in the conventional case.
