Description

[Detailed Description of the Invention] The present invention relates to a flush toilet device, and more particularly to one that can be used as a seat type by placing and fixing a seat body on the top surface of an existing flush Japanese-style toilet.

Conventionally, this type of flush toilet device was developed in 1982.
There is one in Publication No. 13186.

To explain this, there is a nozzle installed on the inner surface of the ball part on the seat body, and either a ball tap water inlet that supplies water directly into the tank, or a water inlet that supplies water into the tank through the hand washing pipe. By connecting either one of them, the water stored in the tank is drained to the Japanese-style toilet bowl, and the waste on the saucer is flushed out into the drainage channel.As the water level in the tank decreases, the ball tap opens and drains the water inside the tank. A portion of the cleaning water that should be stored in the bowl is flushed out of the nozzle to wash away dirt adhering to the inner surface of the ball part.

However, in addition to storing water in the tank, this toilet also flows flushing water from the nozzle, so not only does it require a larger amount of flushing water than existing Japanese-style toilets, but the water flowing into the Japanese-style toilet also flushes out a large amount of flushing water at once. The cleaning process is completed in 5 to 10 seconds, but since the cleaning water flowing from the nozzle uses the cleaning water stored in the tank, it flows in a small amount and for several tens of seconds. There was a fear that the filth that had been washed away would be left behind.

Therefore, the purpose of the present invention is to solve these problems and to make it possible to reliably flush existing Japanese-style toilets without changing the amount of water required for each flush.

The basic configuration of the present invention is that one branched from the secondary side of the water supply device is connected to a rim passageway that has a number of water injection holes for cleaning the inner surface of the ball part of the seat body, and the other is connected to the rim water passageway that has many water injection holes for cleaning the inner surface of the ball part of the seat body. By connecting to a water channel communicating with an outflow hole through which filth is flushed out to a drain port, the cleaning water of the water supply device is made to flow out from the water injection hole and the outflow hole at the same time.

Hereinafter, one embodiment of the present invention will be described based on the drawings.

In this embodiment, as shown in Fig. 1, a Japanese-style flush toilet A is installed on a stepped floor D, and a seat body B is placed above the Japanese-style toilet A to cover it. be.

The seat body B is made of ceramic or synthetic resin such as FRP and has a shape that covers the upper surface of the Japanese-style toilet bowl A. The seat body B has a ball part 2 facing the saucer part 1 of the Japanese-style toilet bowl A in the rear half, and a ball part 2 in the front half. A covering part 5 is formed to cover a front covering part 4 of a Japanese-style toilet bowl A via a stepped part 3.

The ball part 2 is formed into a funnel shape along the rear rim 6 of the Japanese-style toilet bowl A, and its lower end opening edge is inserted into the rear rim 6, and a rim passageway 7 is provided at the upper end opening edge around the entire circumference. .

The rim passageway 7 is formed on the upper part of the ball part 2 so as to protrude inwardly so as to face the inside of the ball part 2, and a number of water injection holes 8 are bored at appropriate intervals on the lower surface of the rim passageway 7. A water supply pipe 9 communicating with the water supply device C is connected to an appropriate location.

In addition, a mounting hole 10 is provided on the upper surface of the middle part of the seat body B.
A hole is opened, and a toilet seat 11 and a lid 12 are rotatably attached above the toilet seat 11 and the lid 12 as required above the hole 10, and a pedestal 13 is provided protruding from the lower end of the outer periphery.
is fixed to the floor surface D using screws 14 or the like.

The water supply device C is a water supply source that supplies water to the so-called flush Japanese-style toilet A, such as a water storage tank or a flush valve. A communicating cleaning pipe 15 is connected, and a branch pipe 16 is provided in the middle of the cleaning pipe 15 to branch into a water supply pipe 9 connected to the rim passageway 7 and a water supply pipe 17 to the toilet bowl A.

On the other hand, the Japanese-style toilet A shown in the drawing is of the so-called flushing type, and has a water supply chamber 18 that communicates with a water pipe 17 branched from the cleaning pipe 15 at the front end, and water is supplied to the water supply chamber 18. A portion of the flush water is introduced from above the chamber 18 to the front cover 4 of the toilet bowl A to wash the inner surface of the front cover 4, and the remaining flush water is channeled through the communication hole 19 drilled into the lower surface of the water supply chamber 18. The waste excreted on the tray part 1 is led through the water channel 20 to the outflow hole 21 formed at the rear end of the toilet bowl A, and the waste excreted on the tray part 1 is flushed out to the drain port part 22. Toilet bowl A that flows into the rim drain hole 24
The inner surface of the ball 25 is cleaned.

At this time, a certain amount of water and water force are required to the outflow hole 21 so that the waste on the saucer part 1 can be reliably flushed out to the drain port part 22, but in this embodiment, the stool body B is The cover part 5 covers the front cover part 4 of the Japanese-style toilet bowl A so that it does not get dirty, and the tip of the branched water pipe 17 is extended to be close to the communication hole 19, or as shown in FIG. As shown, by attaching a water stop plate 26 that partitions the inside of the water supply chamber 18, the cleaning water is prevented from flowing to the front cover part 4, or even if water is passed through, it is kept in a very small amount, so that the cleaning water is directed to the outflow hole 21. We are trying to supply it to

The water stop plate 26 is desirably made of a flexible material such as sponge rubber so that it can easily enter the water supply chamber 18.

Next, Fig. 5 shows another embodiment, in which a Japanese-style toilet A is installed on a flat floor D, and a flush valve is provided as a water supply device C, and a flush valve is installed on the secondary side of the toilet A. A pipe 15 is connected thereto.

The seat body B in this case is formed higher than that of the previous embodiment to make it easier to use.

Incidentally, in both of the above embodiments, a flush type was described as the Japanese-style toilet A, but it is not limited to this and may be of other types. In this case, depending on the structure of the Japanese-style toilet, A water supply pipe 9 may be installed outside the stool body B, pass through the side and top surfaces of the stool body B, and be connected to the rim water passage 7.

In such a flush toilet device, when a predetermined amount of flush water is flushed from a water supply device C such as a tank or a flush valve, a portion of the flush water is passed through a branch pipe 16 to a water supply pipe 9.
The water is sent to the rim passageway 7 through the water injection hole 8, and is discharged from the water injection hole 8 to wash away dirt adhering to the inner surface of the ball 25.
The remaining flushing water flows out from the tip of the water pipe 17 through the waterway 20 of the Japanese-style toilet bowl A, and flows out from the outflow hole 21, flushing out the waste on the saucer part 1 to the drain opening part 22, and flowing out the inside of the ball part 2 of the Japanese-style toilet bowl A. Wash.

Therefore, it is preferable that the branch pipe 16 branches only the amount of water necessary for washing the ball portion 2 of the seat body B from the washing pipe 15 to the water supply pipe 9 side.

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

The secondary side of the water supply system is branched, and one side is connected to a rim passageway with many water injection holes for cleaning the inner surface of the ball part of the seat body, and the other side is connected to a drain port for draining waste on the saucer part of a Japanese-style toilet. Since it is connected to the water channel that connects to the outflow hole that drains into the toilet, unlike conventional toilets, flushing water does not flow outside the tank, allowing flushing without changing the amount of water required for each flushing of the existing Japanese-style toilet. Since the washing water from the water supply device flows out simultaneously from the water injection hole and the outflow hole, dirt adhering to the inner surface of the ball part does not remain in the saucer part after washing, unlike in the conventional case, and cleaning can be ensured.

If the front cover of a Japanese-style toilet with a seat body is covered to prevent it from getting dirty, it not only looks good but also saves water used for cleaning the inner surface of the front cover.
