Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for preventing a toilet seat from being washed with hot water.

[0002]

2. Description of the Related Art Conventional hot water washing toilet seat dirt prevention devices are:
For example, as shown in FIG. 1, a case cover 2 is attached to a rear upper surface of the toilet body 1, and a toilet seat 2 a and a toilet lid 2 b are pivotally attached to left and right side surfaces of the case cover 2. Various functional components such as a nozzle device 3, a hot air drying device 4, and a deodorizing device 5 are built in the case cover 2 as shown in FIG. As shown in FIG. 3, the nozzle device 3 is covered with the nozzle cover 3e in the water discharge direction. When water is discharged in a state where the nozzle device 3 is housed before and after the local cleaning, the nozzle cover 3e repels the water discharged. The tip of the nozzle device 3 is cleaned.

[0003]

In such a warm water flush toilet seat, in the case of local cleaning after excretion, scattered excrement adheres to the periphery of the opening other than the nozzle, causing dirt and foul odor, which is preferable for hygiene. There was no problem. Also,
In the case of a warm water flush toilet seat where it is difficult to attach / detach the hot water flush toilet seat, such as a toilet-integrated warm water flush toilet seat, even if small water or dirty water enters the minute gap between the upper surface of the toilet bowl and the bottom of the case plate, this part is cleaned. However, there is a problem that it is not hygienic and unfavorable in terms of hygiene because it causes dirt and odor. SUMMARY OF THE INVENTION In order to solve such a problem, an object of the present invention is to clean and clean the space between the upper surface of a toilet bowl and the back surface of a case plate of a hot water flush toilet seat body.

[0004]

Means for Solving the Problems To solve the above-mentioned problems, the first aspect of the present invention is designed so that the opening of the duct for blowing and suctioning the hot water flush toilet seat can be cleaned. This makes it possible to clean small water and scattered excrement attached to the duct.

In order to solve the above-mentioned problem, in claim 2, the upper surface of the toilet is inclined toward the bowl portion of the toilet. By doing so, the flushed water on the upper surface of the toilet bowl can be made to flow down.

[0006] In order to solve the above problem, in claim 3, the front surface of the case cover facing the bowl portion of the toilet bowl is provided with a hanging down below the extension of the upper surface of the toilet bowl. By doing so, it is possible to make it difficult for small water and excreta scattered during local washing to enter the duct.

[0007] In order to solve the above-mentioned problem, in claim 4, an opening serving as an outlet from the warm water washing toilet seat to the outside is washed. This makes it possible to clean the periphery of the opening without newly forming a flow path and an opening for discharge of the cleaning water after cleaning the periphery of the opening.

In order to solve the above problem, in claim 5, a member having a sealing function is disposed between the upper surface of the toilet and the case plate of the body of the toilet seat. This can prevent intrusion of small water and the like.

In order to solve the above problem, in claim 6, the cleaning range is limited by a member having a sealing function. By doing so, the flush water after flushing can be discharged in the direction of the toilet bowl.

[0010] In order to solve the above problem, in claim 7, the washing water after washing can be easily discharged to the bowl portion of the toilet bowl. By doing so, the waste water after washing can be quickly discharged to the outside of the warm water washing toilet seat.

[0011] In order to solve the above-mentioned problem, in claim 8, the cleaning water after cleaning is branched into a flow passage for local cleaning. In this way, the section up to the flow path switching device can share the normal water flow path, and the space for installing the piping can be reduced.

In order to solve the above problem, a ninth aspect of the present invention provides a water passage for cleaning. By doing so, there is no need to branch the switching to the water passage for local cleaning by the flow path switching device, so that the effect on the water discharge performance at the time of local cleaning can be reduced.

In order to solve the above-mentioned problem, in claim 10, the cleaning operation method is automatically controlled or manually operated. By doing so, the area around the opening of the warm water flush toilet seat can be cleaned at any time.

[0014] In order to solve the above-mentioned problem, in claim 11, the cleaning portion is periodically dried. By doing so, it is possible to forcibly remove the water in the washing portion, so that the growth of bacteria can be suppressed.
