Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hand-washing device for sterilizing and disinfecting with acidic water obtained by electrolyzing mixed water of tap water and salt water.

[0002]

2. Description of the Related Art Conventionally, for disinfection of hands in a hospital or the like, disinfecting water of a chemical disinfectant such as a chlorine-based disinfecting solution, for example, sodium hypochlorite is used. However, as it is repeatedly used, side effects such as contamination by organic substances, deterioration of bactericidal effect, and irritation of skin and rough hands are caused.

On the other hand, acidic water obtained by adding a trace amount of sodium chloride to clean water and electrolyzing it has a pH of about 3
Since it has the following strong acidity and high active chlorine and exhibits bactericidal activity, it can be used as a disinfectant.

[0004]

By the way, this acidic water has a pH of about 3 or less, and the pH of alkaline water simultaneously produced by electrolysis becomes about 12, and after use, it corrodes the pipes when drained, and P when draining from business establishments such as
There is a problem that the H standard is exceeded, and a measure for complying with the pH standard is required, and the measure is complicated. The present invention has been made in consideration of the above points, and an object of the present invention is to provide a hand-washing device that corresponds to the pH standard, prevents corrosion of piping, and can be easily used.

[0005]

In order to solve the above-mentioned problems, the hand washing device of the present invention comprises a washbasin to which a drain pipe is connected, an acidic water tank storing acidic water, and an acidic water in the acidic water tank. It is provided with a water supply means for supplying water to the washbasin via a water supply pipe, and a drainage tank for storing alkaline water and connected to the drainage pipe for storing acidic water.

The present invention also provides an acidic water supply pipe connected to an acidic water tank and having a water supply port located above the washbasin; an alkaline water supply pipe connected to an alkaline water tank for supplying water to the washbasin; The acidic water in the tank is supplied to the washbasin via the acidic water supply pipe, and the alkaline water in the tank is supplied to the washbasin via the alkaline water supply pipe in association with the water supply. And a water supply means for neutralizing the water.

[0007]

The hand-washing device of the present invention configured as described above is provided with a water supply means for supplying acidic water in the acidic water tank to the washbasin through the water supply pipe, and a drainage pipe storing alkaline water in the drainage pipe. Since the acid water after use is stored via the drain pipe, the acid water after use is neutralized with the alkaline water in the drain tank and then drained, so there is no corrosion of the pipes. It can be used easily, and can meet the pH standard without exceeding the pH standard when draining from business establishments such as hospitals.

Further, the water supply means supplies the acidic water in the acidic water tank to the basin through the acidic water supply pipe, and in conjunction with this water supply, the alkaline water in the alkaline water tank passes through the alkaline water supply pipe. I decided to supply water to the washbasin,
The acidic water after use is neutralized with alkaline water in the wash basin and drained, which has substantially the same effect as described above.
