In general, toilets are not only used by individuals but can only be used by several people, so it is inevitable to feel uncomfortable in the use of the toilet. In particular, the toilet seat is a direct contact part of the human body. 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 hygiene 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 cleaning 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 the problems of hygiene and unpleasant feelings in the use of toilets, in particular, the use of toilet seats, and as a result, in the specification of Utility Model Application No. 20-2000-020588, An annular seat formed on the upper part of the toilet seat and formed of a transparent upper plate, an intermediate plate and a lower plate, a sterilization device installed inside the seat and emitting ultraviolet rays through the transparent upper plate of the seat, and an intake air formed in the lower plate of the seat A deodorizing device comprising a odor feed channel formed between a ball and a lower plate and an intermediate plate of the seat and a deodorizing chamber integrally coupled to the rear of the seat, and controlling the operation of the sterilizing device and the deodorizing device provided at the rear of the seat. Seat for toilet seat equipped with a sterilization and deodorizing device, characterized in that configured to include a device Is described.

However, in the case of the toilet seat, the power loss is large because sterilization by the left ultraviolet lamp and the reflector and deodorization by the deodorizing device are performed separately, and since the left infrared lamp is installed inside the transparent top plate, the disinfection effect by ultraviolet rays is halved In addition, there is a risk that the ultraviolet lamp is damaged when excessive load is applied, and when the reflecting plate is dirty, there is a problem that the sterilization effect by ultraviolet rays is further reduced. In addition, since overexposure to ultraviolet rays generally causes not only skin diseases but also severe skin cancer, in the case of the toilet seat, ultraviolet rays emitted from an ultraviolet lamp cannot cause a possibility of causing a health problem for a user.

Therefore, the present invention simultaneously performs sterilization, deodorization, and air purification by ozone to prevent the spread of contact skin diseases and to relieve discomfort, and to clean the air of the entire toilet, and semi-permanent use with minimum power. It is based on the task of providing a seat system for a possible toilet seat.
