Description

[Detailed Description of the Invention] The present invention relates to a flush Japanese-style toilet bowl equipped with a trap drainage channel cleaning port.

Flush type Japanese-style toilets, which have traditionally been used in frequently used places such as public toilets, have their trap drains buried under the floor, and the trap drains are S-shaped. It is bent in a shape.

For this reason, the trap drainage channel is often blocked by foreign objects such as combs and ballpoint pens accidentally dropped into the container.

As a solution to this problem, for example, toilet bowls with a removable trap or toilet bowls with a cleaning opening that can be opened and closed by a lid on the inner wall of the toilet bowl above the outlet have been devised and used.

However, since all of these have removable parts installed inside the toilet bowl, dirt, etc. can stick and remain in the gaps between the fitting parts, which is not only unfavorable from a sanitary standpoint, but also requires frequent cleaning. There were problems such as the need for maintenance and management.

In order to solve this problem, as described in Japanese Utility Model Application Publication No. 55-131383, a side channel is integrally provided on the outside of the toilet bowl part, and the lower end of the side channel is opened near the drain outlet of the trap drainage channel. A Japanese-style flush toilet has been proposed in which the top end is open to the floor surface on which the toilet is mounted, the top opening is used as a cleaning port, and the cleaning port is provided with a lid that can be opened and closed.

As a result, the above-mentioned problems have been almost solved, but since the whole device is made of ceramic, the cleaning opening part may be deformed, tilted, or the height may be out of order.

For this reason, when the toilet is installed on the floor, the cleaning port protrudes or sinks from the floor surface, which is an issue that needs to be improved, as well as the complete prevention of odor leakage from the cleaning port, and the prevention of tampering with the lid. There are still issues to be resolved, such as measures to prevent the removal of items.

The purpose of the present invention is to provide an improved cover structure for the cleaning port in the above-mentioned conventional flushing Japanese-style toilet bowl, which is equipped with a cleaning port for the trap drainage channel on the outside of the toilet bowl and above the side surface. An extension frame made of metal or plastic is prepared separately from the toilet main body, and this is connected to the upper opening of the side channel so that its position can be adjusted to form a cleaning opening.

The details of the present invention will be explained below based on the embodiments shown in the drawings.

In FIGS. 1 and 2, A is a toilet bowl main body, which communicates a discharge port 1 opened on the rear lower surface with a toilet bowl portion B formed on the upper surface via a trap drainage channel 2. , the same trap drainage channel 2 is connected to the water reservoir recess 3 and the same water reservoir recess 3
A trap portion 5 is formed by a partition wall portion 4 hanging inside,
As a result, the discharge port 1 side and the toilet bowl part B side are water-sealed.

The toilet bowl part B has a toilet receiving part 6 formed therein, and a washing water spouting hole 7 at a position opposite to the entrance 2' side of the trap drainage channel 2.
The filth in the toilet receptacle 6 is washed away by the jet of water from the washing water spout 7 to the entrance 2' of the trap drainage channel 2, falls into the trap section 5, and is discharged along with the water flow through the trap drainage channel 2. It is designed to be discharged outside the toilet bowl from outlet 1.

In addition, the outer wall near the outlet 1 of the trap drainage channel 2 is connected to the toilet bowl part B.
A side passage 8 is integrally provided by protruding rearwardly and outwardly, and the lower end of the side passage 8 is brought into open communication with the vicinity of the outlet 1 of the trap drainage passage 2.

The upper end opening 8' of the side passage 8 opens at a position slightly lower than the toilet mounting floor surface f.

A separate extension frame 9 is connected to the edge of this opening 8', the opening position is raised to almost the same level as the toilet mounting floor surface f, and the upper end opening of this extension frame 9 is connected to the cleaning opening 10. It is said that

The cleaning port 10 is provided with a lid 11 that can be opened and closed, and the cleaning port 10 is normally closed by the lid 11.

As shown in FIG. 3, the extension frame 9 takes the form of a cylindrical extension frame body 9' made of metal or plastic, which is separate from the toilet bowl body A made of ceramic.

The lower end of the extension frame main body 9' is installed on a protruding edge 8'' provided around the inner peripheral surface of the upper end opening 8' of the side channel 8.

For this installation, if necessary, place a spacer of an appropriate thickness on the protruding edge 8'', finely adjust the height and inclination of the upper opening of the extension frame 9, and then glue it with adhesive 12. Fix it.

Further, a protruding edge 9'' is provided on the inner circumferential surface of the upper end opening of the extension frame main body 9', and has a structure for locking the lid 11.

FIG. 4 shows another embodiment of the extension frame 9 shown in FIG.

As shown in the figure, the extension frame main body 9' is divided into a fixed frame part a and a movable frame part b, which are screwed together.

The level can be freely adjusted according to the conditions of the floor surface f at the installation site of the toilet bowl, and the finish of the floor surface can be made even better.

For example, it is particularly suitable for tiled finishes that may be higher than the planned floor level.

Details of the lid body 11 are shown in FIGS. 5 and 6.

As shown in the figure, the back surface of the lid body 11 is provided with a packing 13 at a location opposite to the protruding edge 8'', and a plurality of packings 13 are provided on the back surface of the lid 11 at a location opposite to the protruding edge 9''. Elastic leg piece 14
In addition, a notch 15 for inserting a lid opening tool is provided on one side of the outer peripheral edge of the lid 11.

Therefore, the lid 11 can be attached simply by strongly pressing the lid 11 against the cleaning opening 10, and by inserting a tool such as a screwdriver into the notch 15, the lid 11 can be easily removed and cleaned by lever action. Mouth 10 can be opened.

This invention makes it possible and easy to adjust the level with the floor surface on which the toilet is mounted, making it possible to achieve a uniform finish when the toilet body is buried under the floor surface, and to avoid cleaning that occurs due to variations in firing or dimensions, which is a drawback of ceramics. There is no need to worry about the inclination of the mouth, mismatch in level, etc., the cleaning opening can be reliably blocked by the lid, and it can be made into a Japanese-style toilet with a good-looking cleaning date, which has great practical value. be.
