JPS6035669Y2 - Japanese-style toilet bowl for flush toilets - Google Patents

Description

[Detailed description of the invention] The tail end of Japanese-style toilets in flush toilets installed at stations, parks, etc. is often soiled with excrement, which often gives the next user an unpleasant feeling.

This is due to the toilet being used in a too receding position, and there are cases where the toilet is so dirty that the user has no choice but to refrain from using it.

It is an object of the present invention to avoid the above-mentioned disadvantages and to easily provide a part for repairing clogging failures occurring in the trap section in conjunction with a structure for avoiding the above-mentioned disadvantages.

In order to achieve the above-mentioned purpose, the present invention has two washing recesses in the front and back to wash away dirt with washing water spouting from the periphery.
In addition to making the rear flushing recess shallower than the front flushing recess, the bottom of the rear flushing recess is sloped downward toward the front flushing recess, and the water sealing part of the trap is connected to the drain outlet. A cleaning branch pipe is provided that branches from the flow path leading to the cleaning pipe and rises toward the rear flushing recess, and an embolus that closes the top opening of this cleaning branch pipe is provided at the bottom of the rear flushing recess.

The rear flushing recess in this device receives the excrement that would have soiled the toilet bowl when the conventional toilet bowl is used in an overly receding position and flushes it away with flushing water.

The rear flushing recess is shallow, so its existence is not very noticeable from the outside.

In the following, the above-mentioned invention will be explained with reference to figures.

In the figure, 1 is the toilet bowl, and 2 is its top surface.

The top surface 2 is flat and the outer periphery 3 is given a rectangular contour.

3a is a corner of the top surface 2, 4 is a toilet floor, 5 is a tile placed on the floor, and 6 is a frame to which a toilet is attached.

In order to provide a rear flushing recess that follows the front flushing recess, the top surface 2 of the toilet bowl 1 is extended rearward longer than in conventional toilet bowls.

7 indicates the overhanging top surface portion.

8 is the bottom of the front flushing recess, 9 is an opening provided at the rear end of the bottom 8, 10 is a trap, 10a is a water sealing part, and 11 is a drain port.

12 is the bottom of the rear flushing recess, which is sloped downward toward the front flushing recess.

Washing water from an inlet 13 provided at the front end of the toilet bowl 1 is discharged into the front and rear flush recesses.

Water is discharged to the front washing recess through the opening 14 on the front end side of the bottom 8.
The water is discharged through an opening 16 of a water channel 15 provided along the lower surface of the top surface 2, and the water is discharged to the rear washing recess through an opening 18 of a water channel 17 connected to the water channel 15.

The washing water discharged through the opening 18 of the water channel 17 flows down while washing the bottom of the rear washing recess and enters the front washing recess.

The rear flushing recess serves to receive some of the excrement and flush it into the front flushing recess when the toilet bowl is used in a too receding position.

The supply of flushing water that occurs when the flush valve is operated continues for a considerable period of time, so the supplied flushing water not only covers the excrement that has directly entered the front flushing cavity but also the rear flushing cavity. The excrement that has entered the front flushing recess through this process is also washed away.

A cleaning branch pipe 20 is provided in a flow path leading from the water sealing portion 10a of the trap 10 through the bent portion 19 to the drain port 11, which branches from the flow path and rises toward the rear flushing recess.

21 is the top opening of the cleaning branch pipe, and 23 is an embol that fits into the top opening 21 at a threaded portion 22, and is provided on the bottom 12 of the rear flushing recess.

The cleaning branch pipe 20 is a short pipe in a direction close to the acute direction, and its lower end is located at a location immediately after the water sealing part 10a where clogging is likely to occur, so it is difficult to repair if clogging occurs. The work is done very easily.

As explained above, the present invention prevents dirt from forming at the tail end of the toilet due to use of the toilet in an excessively receding position, and also makes it easy to repair if a blockage occurs. It is intended to do so.

Japanese-style toilets in station toilets and public toilets often have excrement attached to the tail end, causing discomfort to toilet users.

This project aims to improve this problem by installing an visually unnoticeable flush recess at the rear, and also prevents clogging of the Japanese-style toilets in this type of toilet due to the use of inappropriate paper or cloth. This allows for easy repair by installing a branch pipe for cleaning in conjunction with the installation of the recess.
