Description

Automatic sterilization cleaning system of seat for toilet seat {AN AUTOMATIC STERILIZING AND WASHING SYSTEM OF A SEAT FOR STOOL}

The present invention relates to an automatic sterilization cleaning system for a toilet seat, and more particularly, while one of the two toilet seats are used externally, the other one is sterilized and prepared in a sterilization washing room, and is reused. The toilet seat for which the sterile cleaning has been completed in advance is moved to the outside of the sterile washing chamber, and the already used toilet seat is directed to the automatic sterilizing washing system of the toilet seat which is moved into the sterile washing room for reuse and sterilized and prepared.

In general, toilets are not only used by individuals but can be used together by several people, so it is inevitable to feel uncomfortable in using the toilet. In particular, since the toilet seat is a direct contact part of the human body, various pathogens including contact skin diseases There are hygiene problems to be transmitted. In particular, in the case of toilets in public places such as subway stations, department stores, companies, schools, parks, discomfort and hygiene problems are further increased.

In addition, the survey results show that the biggest inconvenience of foreign tourists visiting Korea is the hygiene and cleanliness of public toilets, and the number of foreign tourists is increasing rapidly following the year of visiting Korea and the 2002 World Cup. In recent years, public awareness of the toilet culture has been increasing, and the problem of the sanitation and cleanliness in toilets, especially toilet seats, has become a government issue.

Some luxury hotels have separate disposable rugs in the bathrooms, but due to the cost of consumption and disposal of disposable rugs, and due to environmental restrictions on the use of disposable items and disposal of garbage, The use of the disposable rug has not been popularized, so in the case of general users, the toilet should be used after laying toilet paper on the toilet seat or wiping the toilet seat with toilet paper. Even if the discomfort associated with the use of others is not completely eliminated, and hygiene problems caused by pathogen transmission are not excluded.

Therefore, a lot of research has been conducted to solve hygiene problems and unpleasant feelings in the use of toilets, in particular, the use of toilet seats. As a result, Utility Model Application No. 20-2000-0019595 is isolated in an unattended self-cleaning public toilet. The lower part of the wall is provided with a rotating wall, and a pair of toilet seats are symmetrically mounted on both sides of the rotating wall, and the toilet seat has a built-in thermostat equipped with a heating element, and the washing room has a toilet part. When the toilet seat used in the toilet is rotated and placed in the washing room, the sterilizing and disinfectant solution is sprayed at high pressure on the toilet seat which is first washed by the automatic brush washer and the brush washer that washes the toilet seat, such as washing a car with a car washer. It is equipped with a water spray washer to wash the second time and a hot air dryer to dry the toilet seat after the second wash. When the rotating wall is rotated 180 degrees, the toilet seat is also rotated together, so that the toilet seat is attached to the rotating wall while the toilet seat is washed and dried in the washing room opposite the isolation wall. Unattended self-cleaning public toilets are known in which the toilet seat rotates.

However, the conventional unattended self-cleaning public toilet as described above requires a relatively large washing room space required for 180 degree rotation by the rotating wall, so that the utilization of space is lowered, and the cleaning process is also performed by the brush. And since it takes a lot of time to secondary washing, drying by high-pressure injection of the disinfectant solution may be necessary to use a toilet seat that is not properly washed and dried, there is a problem in that the sterilization cleaning effect is lower than the required time.

Therefore, the present invention can be used by sterilizing and washing two sheets alternately even in a small space sterilization washing room, excellent in space utilization, and can obtain an excellent sterilizing washing effect in a short time to solve the user's discomfort It is based on the task of providing an automatic sterilization cleaning system for seats for toilet seats that can promote hygiene and health.

The task is a sterilization washing chamber is installed between the left toilet seat and the water tank by sliding the two seats of the elastic material through the seat guide alternately, the seat guide has two seats so that the two seats each slide out Branched by a guide line, the two seats are connected by a rod and a joint installed in one side in the sterilization washing chamber, respectively, a drive motor for reciprocating both rods vertically alternately in the lower portion of each of the rods, lift stop A sensor and a down stop sensor are respectively installed, and inside the sterilization washing chamber, a sterilizing washing apparatus for sterilizing and washing both sheets alternately located is installed at one upper portion, and a control device for controlling all the operations is at the other upper portion. Installed, the operation / instructions are installed on the sterilization washing chamber, automatic of the seat for the toilet according to the invention Is achieved by the bacteria wash system.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
