Description

[Detailed description of the invention] The present invention is a flush toilet device, more specifically, a seat body is mounted and fixed so as to cover an existing flush Japanese-style toilet so that the Japanese-style toilet can be used as a seat type. It concerns the improvement of structures for water supply.

There are two types of flush toilets: Japanese-style toilets and Western-style seated toilets. Japanese-style toilets are installed embedded in the floor, so once installed, it is difficult to replace them with a seated toilet.

Therefore, there is a toilet device in which a seat body is installed to cover a Japanese-style toilet bowl so that the Japanese-style toilet bowl can be used as a seated toilet bowl, and the one disclosed in Utility Model Application Publication No. 56-13186 is known as a conventional toilet device of this type. ing.

This product branches the water supply pipe for washing the seat body from the ball tap part provided in the washing tank.
The water is communicated with a nozzle provided on the seat body so as to spray water onto the inner surface of the ball part, thereby cleaning the ball part of the seat body.

However, since the positional relationship between the cleaning tank and the Japanese-style toilet differs from toilet to toilet, the distance (sum of horizontal distance and vertical distance) and direction between the ball tap and the Japanese-style toilet vary. The length of the water supply pipe for cleaning the stool body must be adjusted according to the distance and direction, which makes piping the water supply pipe troublesome, and if the length of the water supply pipe is long, the flow path resistance of the pipe As a result, the amount of water supplied decreases, and the ball portion of the seat body is not sufficiently cleaned, and the ball portion of the seat body may not be sufficiently cleaned.

Therefore, if the water supply pipe to the seat body is branched from the toilet flush pipe that connects the flush tank and the Japanese-style toilet bowl, the length of the water supply pipe can be shortened by the vertical distance mentioned above. Depending on the location of the cleaning tank, it is oriented radially around the area where it is attached to the toilet bowl, and the distance between the water supply port of the seat body and the branch port of the toilet flush pipe and the direction of the branch port relative to the water supply port are determined at each site. It is necessary to easily select the water supply pipe according to the horizontal distance and direction by selecting several types of water supply pipes corresponding to the respective installation directions to the above two ports and the length between the two ports. The work is troublesome.

In addition, it is possible to use flexible pipes such as bellows pipes to install the water supply pipes for washing the stool body, but flexible pipes are generally not suitable because they are difficult to cut and connect to any desired length. Therefore, the length is longer, and the extra length is bent and connected, resulting in a longer flow path and making it difficult to clean the ball part of the seat body. There is a possibility that it will be enough.

Therefore, the purpose of this invention is to make it possible to connect a water supply port and a branch port with a set of water supply pipes even in a site where the distance between the water supply port and the branch port and the direction of the branch port with respect to the water supply port are different. The technical problem to be solved by this invention is to make the direction of the shaft plug of the water supply port of the seat body and the branch port of the toilet cleaning pipe vertical, and to adjust it freely according to the horizontal distance between the two ports. is to connect both ends.

The technical means taken by the present invention to achieve the above-mentioned technical problem is to open the water supply port of the seat body on the top surface of the body, and to connect the water supply device and the Japanese-style toilet bowl to supply toilet flush water. A substantially horizontal horizontal pipe section is provided in the middle, and a branch port section is opened on the upper surface of the pipe section, which branches off from the toilet bowl flushing section, connects to the water supply port of the seat body, and supplies cleaning water to the rim passageway of the bowl body. The rim water supply pipe to be supplied is constituted by a first water supply pipe and a second water supply pipe, each of which is formed in a substantially L-shape, and one end of the first water supply pipe is provided on the upper surface of the horizontal pipe part of the toilet flushing pipe. The branch opening and one end of the second water supply pipe are connected to the water supply port of the seat, and the other ends of the first and second water supply pipes are inserted and connected to each other.

Therefore, the axial direction of the water supply port of the seat body and the branch port of the toilet flushing pipe are perpendicular, and by connecting the axes in a straight line, the length of the rim water supply pipe can be shortened. The amount of water supplied to the water passageway may be reduced due to the flow path resistance of the water supply pipe, and the ball part of the seat body may not be able to be sufficiently cleaned. The length can be adjusted depending on how well it is inserted. Therefore, piping work for water supply pipes is easy.

Since the present invention has the above configuration, it has the following advantages.

(1) A rim water supply pipe is branched from the middle of the water supply pipe that connects the water supply system and the Japanese-style toilet, and a part of the water supplied for cleaning the Japanese-style toilet is diverted to cleaning the seat body, so a seat body is provided.
