Description

  The present invention relates to a toilet seat storage method in a toilet seat cleaning apparatus for a Western-style toilet that automatically cleans and dries a used toilet seat.

  Conventionally, in toilet seat cleaning devices for Western-style toilet bowls, the toilet seat surface is washed at once and then dried, or the cleaning liquid is sprayed in a sealed state in which the toilet seat is lifted up and sealed, and steam or air is sprayed. Many proposals have been made on what to dry. Japanese Patent Laid-Open No. 63-97124 discloses a particularly simple structure with a reduced size. This structure is vertically arranged in the rear region of the toilet bowl and has an entrance / exit trap door formed on at least a part of the front surface thereof, and vertically from the use position placed horizontally on the toilet bowl into the sealed container. It is a moving means that functions to guide the toilet seat to the arranged washing position and simultaneously control the opening and closing of the entrance / exit trap door, and is connected to the rear area of the toilet bowl and the entrance / exit trap door by the connecting means, and vertically up and down. Moving means containing a motor-driven assembly to move, cleaning means built in a sealed container and configured to spout wash water onto the toilet seat, and drying means configured to circulate air in the sealed container And a motor-driven assembly, a cleaning means, and a timing control means for the drying means.

  However, in Japanese Patent Laid-Open No. 63-97124, the rear part of the toilet seat is pulled up and stored vertically in a sealed container. At this time, the lower surface of the toilet seat slides on the toilet surface. If it is dirty, the surface of the toilet may become smudged every time, and if hard or sandy debris adheres to the underside of the toilet seat and the surface of the toilet, scratches or paper on the toilet surface. There was a risk of frosted fine scratches such as Furthermore, since the toilet seat surface contacts and rubs against the back surface of the trap door each time, as with the toilet bowl surface, if dirt adheres to the back surface of the trap door, there is a risk that the stain will be applied to the toilet seat surface each time and the trap is trapped. If hard or sandy debris adheres to the back of the door, the toilet seat surface may be scratched or frosted, causing the image of the entire toilet to be down. Also, even if the toilet seat is dried after being cleaned inside the sealed container, it takes a long time to completely dry the toilet seat and the wash water flows downward and is collected. Water droplets are likely to remain, and since the lower part of the trap door and the toilet seat surface come into contact with each other and are set in the toilet bowl, water droplets remain on the toilet seat surface and it is difficult to completely dry.

  For this reason, in the Japanese Patent Application No. 2009-206748, the applicant can wash the front and back sides of the toilet seat at the same time, dry the toilet seat quickly and completely dry it. A toilet seat cleaning device for a Western-style toilet bowl that has a simple structure and that is free from dirt and scratches, has a good appearance, and has no risk of washing water or warm air coming out toward the back of a person. However, since Japanese Patent Application No. 2009-206748 moves the toilet seat erected horizontally, it is difficult to reduce the size of the washing room, and it is difficult to install it in a place with little installation space.
