Description

Automatic handwasher {A auto handwasher}

The present invention relates to an automatic washing device in which water and soap are sprayed at the same time, and the process of drying the washed hands can be performed automatically in one cycle. The present invention relates to an automatic washing device capable of shortening the drying time of a hand by minimizing heat loss by the process.

In general, toilets for public hand washes, various restaurants, and entertainment venues are equipped with hand washing facilities for hand washing. Such toilet facilities are provided with water supplies, soaps and towels so that the user can hygienically wash their hands.

Since the toilet is a place used by many people, it is necessary to clean the area around which soap is placed frequently, and the towels should be replaced frequently so that the toilet can be kept clean without getting dirty. Therefore, in the restaurant or entertainment venues, the toiletries place a lot of care to always maintain the cleanliness, there is also a situation where there is a separate management personnel.

In addition, since public toilets are used by more people than restaurants and entertainment venues, soap is easily consumed and towels are also easily soiled. Therefore, although a separate hygiene manager is employed and managed from time to time, cleanliness in public places that should be kept clean is deteriorated because the hygiene manager alone is insufficient to cleanly clean toilet facilities in public places. Where there is no reach, the problem of having to rely on public awareness of the public is a problem.

On the other hand, when washing hands or face in the sink, there is a problem that the water resources are unnecessary waste because the soap is in the state that the tap water is discharged as it is.

As a solution for overcoming the above problems, the present applicant has a scale such as when soap is sprayed on a spray nozzle or a supply pipe pointed out as a problem of Patent No. 0305500 and its operation control method, and Patent No. 0305500. This suggests the automatic washing device of Utility Model Registration No. 0280087, which improves the problem and the problem of high production cost.

The above structures have the common advantage that they can be used conveniently without the need for a separate soap or towel, and can be utilized as a simple portable washbasin where the sink is not installed or cannot be installed. In addition, the external structure is so large that a separate installation space must be secured when connecting to the water pipe, and since the hand dryer is equipped with the existing hand towel structure, the warm air heat is leaked to the outside during hand drying. High capacity heaters must be applied, which causes a problem of severe waste of power.

Therefore, the present invention has been proposed to solve the above problems, it is possible to install on the wall surface of the sink or small space, and by heating the hot air heat supplied while minimizing the external leakage of the hot air heat to a heater of low capacity It is also an object of the present invention to provide an automatic washing device capable of rapidly drying hands.

In addition, the present invention can be supplied directly connected to the water supply facilities without using a pump when supplying the washing water, automatic washing device that can be used in places where the water supply facilities are not equipped, or where the water pressure of the water supply is low and problems with water quality There is another purpose in providing it.

In addition, the present invention has another object to provide an automatic washing device to reduce the installation cost by allowing the use of several washing machines in one washing water supply.
