Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a hand-washing device comprising a hand-washing device for washing hands and a dryer for drying hands after washing.

<Conventional technology> Conventionally, this type of handwashing device automatically sprays washing water from the basin's spout and then blows out drying air to wash and dry hands without touching anything. Because of this, they are installed in workplaces such as the electronics and food industries, where microscopic dust and bacteria on people's hands and fingers are extremely disliked, and more specifically in clean rooms.

However, conventional products have a problem in that skin aging substances generated by rubbing hands together during drying are diffused into the room along with the drying air.

In addition, when clothes vibrate or cuffs rub together while washing hands, a large amount of fine dust is generated and scattered indoors.

<Problem to be solved by the invention> The problem to be solved by the invention is to reliably discharge dust, skin aging substances, etc. generated during hand washing and drying to the outside.

<Means for solving the problems> The technical means taken by the present invention to solve the above problems is to solve the above problems in a hand washing device consisting of a hand washing basin and a dryer that blows out drying air using a blower fan. An exhaust port that connects to the outdoors via an exhaust fan is provided in the bowl of the wash basin, and the air outlet of the dryer is placed toward the inside of the bowl, and the exhaust fan is activated at least when the above-mentioned blower fan is activated. be.

<Function> In the present invention, the drying air blown into the bowl by the blower fan is discharged to the outside through the exhaust port by the exhaust fan.

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

This embodiment shows a case where the air outlet _b1 of the dryer B is integrally provided in the upper part of the wash basin A, as shown in FIG.

Wash basin A is made of ceramics and synthetic resin,
A bowl portion _a1 formed into a substantially mortar shape, and the bowl portion
A covering part _a2 covering the upper surface of the bowl part _a1 and an exhaust passage _a3 formed at the lower end of the bowl part _a1 are integrally provided.

The bowl part _A1 has a rim water passage _A4 formed in an annular shape around the entire circumference on 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 . As a result, an opening _a5 is opened at the upper front of the wash basin A.

A water supply port _A6 to which the water supply pipe 2 connected to the solenoid valve 1 is connected is provided on the back side of the rim water passage _A4 , and a number of water injection holes _A7 are drilled at appropriate intervals on the bottom surface. Then, the cleaning water supplied from the solenoid valve 1 is sent to the water injection hole.
_A7 ...Water is discharged along the inner surface of the bowl part _A1 to form a water film for cleaning.

In addition, a drain port _a8 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 _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, there is an exhaust port A ₉ that connects to exhaust path A ₃ on the rear side.
will be established.

The exhaust passage _a3 extends obliquely upward from the exhaust port _a9 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 installed in the middle of the exhaust pipe 5. Deploy.

The exhaust fan 6 sucks the air in the bowl part A 1 through the exhaust port A ₉ by making a U-turn at the bottom of the bowl part A ₁ by rotating, and exhausts it to the outside through _the exhaust pipe 5. In the example, the operation is controlled by a sensor 7, which will be described later, so that the air volume changes after a predetermined time from the start of the operation.

That is, while the exhaust fan 6 is discharging cleaning water from the water discharging device 4 (described later), the rotation speed of the exhaust fan 6 is low, and when drying air is blown out from the air outlet b ₁ (described later), the rotation speed increases and the amount of suction increases. is increasing.

On the other hand, the covering part _a2 has a water spouting device 4 for washing the user's hands, an air outlet _b1 of a dryer B for drying the hands after washing, and a sensor 7 for controlling the operation of both.
are arranged in a penetrating manner.

The water discharging device 4 has its upper end connected to a water discharging pipe 8 branched from the secondary side of the electromagnetic valve 1 that supplies wash water to the rim passageway _a4 , and has its lower end protruding inward from the covering portion _a2 . By installing the solenoid valve 1, splashes of washing water supplied from the solenoid valve 1 are prevented from scattering outside the wash basin A.

Dryer B has an air outlet facing into the bowl part _A1 .
b ₁ , a ventilation pipe b ₂ that connects to the air outlet b _{1 and} communicates with the room or outdoors, and a blower fan b ₃ installed in the middle of this ventilation pipe b ₂ . On the downstream side, a heater b ₄ and an air filter b ₅ such as a sterilization filter for removing dust in the air and oxides scattered from the surface of the heater b ₄ are sequentially provided.

Therefore, in the dryer B, indoor or outdoor air warmed by the heater b ₄ is blown out at high speed from the outlet b ₁ into the bowl part a ₁ via the air filter b ₅ .

The sensor 7 is a conventionally well-known photoelectric sensor, and sends a sensing signal to the controller 9 when the user inserts his or her hand into the bowl portion _a1 through the opening _a5 .

The controller 9 is electrically connected to the solenoid valve 1, the exhaust fan 6, the sensor 7, the blower fan b ₃ , and the heater b ₄ , and when a sensing signal is sent from the sensor 7, the controller 9 operates for only 10 to 15 seconds, for example. At the same time as opening the solenoid valve 1, the exhaust fan 6 is rotated at a low rotation speed, and then, for example, the heater _b4 is energized for 30 seconds to 1 minute to generate heat, and the blower fan _b3 is rotated, and then the exhaust fan 6 is turned on. It rotates at 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 in a shower form from the water spouting tool 4 to wash the user's hands, and the air in the bowl part _a1 is further exhausted from the exhaust port _a9 . At the same time as these operations stop, warmed air is discharged from outlet b ₁ ,
In other words, 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 port _a9 is increased, which removes dust from the user and their clothes while washing their hands, and also removes dust from rubbing their hands together. The generated skin aging substances are sucked out and exhausted outside.

In the above-described embodiment, the air outlet b ₁ of the dryer B is integrally provided above the wash basin A, but the present invention is not limited to this, and the air outlet b ₁ is disposed above the wash basin A. You may do so.

In addition, although the operation of the exhaust fan 6 and the ventilation fan _b3 is controlled by the sensor 7, it is not limited to this.
Both of these may be operated by manual switches, and the air volume of the exhaust fan 6 is changed after a predetermined period of time, but the exhaust fan 6 may be operated at least when the blower fan b ₃ is activated. The exhaust fan 6 may be rotated at the same time as the drying air is blown out from the air outlet b ₁ without any change.

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

Since the drying air blown into the bowl part by the blower fan is discharged to the outside by the exhaust fan from the exhaust port, dust and skin aging substances generated during hand washing and drying can be reliably discharged to the outside.

Therefore, skin aging substances generated by rubbing one's hands together will not be diffused into the room together with the drying air, unlike the conventional method, and dust generated during hand washing will not be scattered into the room.
