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 and 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 its front surface, 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 smeared every time, and if hard or sandy debris adheres to the underside of the toilet seat and the toilet surface, scratches or paper may appear on the toilet surface. There was a risk of frosted fine scratches. Furthermore, since the toilet seat surface contacts and rubs against the back surface of the trap door every 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 that has a simple structure and does not have dirt or scratches, has a good appearance, and has no risk of washing water or warm air coming out toward a person's back. 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.

In addition, the rotary shaft (4) is fixed to the rear end of the toilet seat (2), and the gear (5) is fixed to the end of the rotary shaft (4), and the rack portion (6) is provided below the washing chamber (3). By using a mechanism in which the toilet seat (2) is stowed upright in the washing chamber (3) while the gear (5) meshes with the rack portion (6), the structure is ensured with a simple structure. In addition, the toilet seat (2) can be stored upright in the cleaning chamber (3), and the production cost can be reduced.

It is explanatory drawing which shows operation | movement of embodiment of this invention method. It is explanatory drawing which shows the principal part of the toilet seat washing | cleaning apparatus used by this embodiment.

  In order to make the toilet seat cleaning apparatus proposed by the applicant in Japanese Patent Application No. 2009-206748 compact and expand the application, the front part of the toilet seat (2) is lifted, and the toilet seat (2) is located below the cleaning chamber (3). This was realized by a toilet seat storage method that stood and stored while moving.

  FIG. 1 and FIG. 2 are diagrams showing an embodiment of the method of the present invention. Although (1) is a Western-style general toilet, it is good also as what shortened the back of this toilet (1). (2) is a toilet seat that can be lifted from above the toilet bowl (1), and the rear end portion of the toilet seat (2) is fixed by penetrating the rotary shaft (4). (3) is a sealable washing room provided with an automatic door on the front, and the washing room (3) is arranged at the rear of the toilet (1). In addition, when the automatic door is opened, the space in which the toilet seat (2) is accommodated in the washing room (3) with a margin is secured. (5) is a fan-shaped gear fixed to both ends of the rotating shaft (4), and the gear (5) is not limited to a fan shape, and a general circular gear may be used. One gear (5) may be fixed to the center of the rotating shaft (4). (6) is a rack portion that meshes with the gear (5), and the rack portion (6) is inclined rearward (right side) and downward. The rack portion (6) may be formed by forming a spur portion on a slope of a triangular base or fixing a flat gear itself. Further, when the inclination of the rack portion (6) is increased (steeply), the depth of the cleaning chamber (3) can be shortened (narrowed) according to the inclination.

  A method of lifting the toilet seat (2) of the toilet bowl (1) and storing the toilet seat (2) upright in the washing chamber (3) and washing and drying the toilet seat (2) in the sealed washing chamber (3). The surface side cleaning method generally used may be used, but is preferably substantially the same as Japanese Patent Application No. 2009-206748 proposed by the applicant. The basic configuration of the toilet seat storage means may be substantially the same as that of Japanese Patent Application No. 2009-206748 proposed by the applicant. The guide member (not shown) may be of the same basic structure as that of Japanese Patent Application No. 2009-206748, but it may be simply a plate-like member that guides both sides of the gear (5). .

  Next, the toilet seat storage method of the present invention will be described with reference to FIG. First, when a person leaves the toilet (1) after use, an instruction from a sensor (not shown) is sent to a mechanism for storing the toilet seat (2) by a control box (not shown). Then, the rotating shaft (4) is rotated by a drive motor (not shown), and the gear (5) rotates and the toilet seat (2) is lifted while rotating as indicated by the dotted arrow shown in FIG. Further, since the gear (5) meshes with the top of the inclined rack portion (6), the rotating shaft (4) moves rearward (right side) and downward while rotating. That is, the front end of the toilet seat (2) is lifted and comes from the position of the two-dot chain line to the position of the thick solid line, and the gear (5) moves to the center position of the rack portion (6). When the gear (5) further rotates and meshes on the rack portion (6), the toilet seat (2) is housed in the washing chamber (3) at the standing middle position. And the drive motor stops. At this time, the rotating shaft (4) or the gear (5) is preferably arranged so as to move smoothly by a guide member (not shown).

  After the rotation shaft (4) is stopped, the toilet seat (2) is washed with the washing liquid in the sealed washing chamber (3) and dried by jetting air, as in Japanese Patent Application No. 2009-206748. Then, after the drying is finished, the automatic opening / closing door is opened according to the instruction of the control box, and the toilet seat (2) is taken out from the washing room (3) while gradually tilting the toilet seat (2), and the toilet seat (2) is removed from the toilet bowl. (1) Place on top. After that, the automatic door is closed. Thus, the above process is repeated. The toilet seat (2) is preferably cleaned every time it is used, but the number of people may be detected and cleaned every few people.

  As described above, the method of the present invention rotates so that the front portion of the toilet seat (2) is lifted, and the toilet seat (2) is accommodated while moving downward of the cleaning chamber (3). It is lower than that of Japanese Patent Application No. 2009-206748 and can be made compact, and can be installed as a toilet for a vehicle such as a bullet train or an airplane. When the toilet seat (2) is stored in the washing chamber (3), the rotary shaft (4) is fixed to the rear end of the toilet seat (2), and the gear (5) is attached to the end of the rotary shaft (4). The rack portion (6) is inclined and arranged at the lower part of the washing chamber (3), and the toilet seat (2) is erected in the washing chamber (3) while the gear (5) meshes with the rack portion (6). By using the mechanism housed in the state, the depth of the cleaning chamber (3) can be further reduced, and further downsizing can be achieved.
