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 shown in FIG. 5 has been described in Japanese Utility Model Application Publication No. 56-13186.

To explain this, the lower end opening of the ball part b1' formed on the seat body B' is a Japanese-style toilet.
Since it is located at the entrance of the saucer part a1' of A', when sewage and filth are discharged into the saucer part a1', the sewage that bounces back onto the back side of the seat body B' and the rim a of the Japanese-style toilet bowl A.
4' Adheres to the inner surface and top surface.

These stains caused by sewage cannot be washed away with washing water, and cleaning cannot be done without taking the trouble to remove the seat body B', resulting in the problem of accumulation and generation of odors.

Therefore, the present invention aims to solve the above-mentioned problems and to keep both the Japanese-style toilet bowl and the seat body clean, thereby preventing the generation of dirt and the accompanying odor.

The basic structure of the present invention is that the opening at the lower end of the ball of the seat body protrudes downward from the rim drain hole of the existing Japanese-style toilet, so that the splashed sewage flows upward from the rim drain hole. This is to prevent it from sticking.

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

The existing flush-type Japanese-style toilet A has a structure and form that are well known in this type of technical field, and the one shown in Fig. 1 has a saucer portion a1 at the rear of the interior, and is continuous with the saucer portion a1 at the front of the lower part. This is a so-called flushing type toilet in which a trap part a2 is formed respectively, and a seat body B is placed above the Japanese-style toilet A so as to cover it.

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, and has a ball part b1 facing into the Japanese-style toilet bowl A in the rear half thereof, and a stepped part b2 in the front half part. A covering part b3 is formed to cover the front covering part a3 of the Japanese-style toilet bowl A through.

The ball part b1 is formed in a funnel shape along the rear part of the rim a4 of the Japanese-style toilet bowl A, and its lower end opening is inserted into the rim a4 and projects downward from the rim drain hole a5 formed at the upper peripheral edge of the Japanese-style toilet bowl A. The container is placed close to the tray portion a1 to such an extent that it does not interfere with the flow of water during washing and the washing away of dirt.

Incidentally, an arch-shaped recess b4 may be formed on the front side of the lower end opening of the ball part b1 of the stool body B to prevent dirt from getting caught when washing away dirt.

Further, a rim water passage b5 is provided at the upper end opening of the ball portion b1 over the entire circumference.

The rim water passage b5 is located above the ball portion b1,
A water supply pipe 1 is formed to protrude inward so as to face inside the ball portion b1, has a number of water injection holes b6 opened at appropriate intervals on its lower surface, and communicates with the water supply device C at an appropriate location of the water passage b5. Connect.

Further, a mounting hole 2 is drilled in the upper surface of the middle part of the seat body B, and a toilet seat 3 and a lid 4 are rotatably mounted above the toilet seat 3 and the lid 4 are attached to the hole 2 as needed, and a pedestal B7 is mounted on the lower end of the outer periphery. protrude, and attach this pedestal b7 with screw 5.
etc. to fix it to the floor D.

The water supply device C is a water supply source that supplies water to an existing flush-type Japanese-style toilet A, such as a water storage tank or a flush valve. In this embodiment, a tank is shown, and the Japanese-style toilet A and the water supply device C are installed on the secondary side, that is, at the drain port of the tank. A communicating cleaning pipe 6 is connected, and a branch pipe 7 is provided in the middle of the cleaning pipe 6 to branch into a water supply pipe 1 connected to the rim water passage b5 and a water supply pipe 8 to the toilet bowl A.

On the other hand, a water supply chamber a6 is formed at the front end of the Japanese-style toilet A and communicates with a water pipe 8 branched from the cleaning pipe 6. The water is then led to the front cover part a3 of the toilet bowl A to wash the inner surface of the front cover part a3, and the remaining washing water is passed through the water channel a through the communication hole a7 drilled on the lower surface of the water supply chamber a6.
8 to the outflow hole a9 formed at the rear end of the toilet bowl A, and the waste excreted on the tray part a1 is collected in the trap part a.
2 to the drain port a10, and also flows from the middle of the waterway a8 to the rim drain hole a5 through the rim communication hole a11 of the toilet bowl A.
12 The inner surface is cleaned.

Next, FIG. 4 shows another embodiment, in which an existing flush-type Japanese-style toilet A has a saucer part a1 at the front of the interior and a trap part a2 continuous to the saucer part a1 at the rear of the lower part. In this case, the lower end opening of the ball part b1 formed on the seat body B is the trap part a2 of the Japanese-style toilet A.
Project downward toward the entrance.

In such a flush toilet device, when a predetermined amount of flushing water is flowed from a water supply device C such as a tank or a flush valve, a part of the flushing water is sent to the rim of the seat body B through a branch pipe 7 and a water supply pipe 1. The water is sent to the water passage b5 and discharged from the water injection hole b6 to wash away the dirt adhering to the inner surface of the ball part b1, and the remaining washing water is sent from the tip of the water pipe 8 to the water passage a8 of the Japanese-style toilet A and then discharged from the water injection hole a.
9 flows out onto the saucer part a1 or trap part a2
The filth inside is flushed out to the drain port a10, and the inner surface of the bowl a12 of the Japanese-style toilet A is cleaned.

In the above-mentioned embodiment, the water supply to the seat body B is branched from the secondary side of the water supply device C, but the present invention is not limited thereto. You can also supply water to

In addition, although a type in which the Japanese-style toilet A is installed on a stepped floor surface D is shown, the present invention is not limited to this, and the same applies even in the case of a type in which the Japanese-style toilet A is installed on a flat floor surface. Needless to say.

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

A rim water passageway with a number of water injection holes for cleaning the inner surface of the ball part is provided at the upper end opening of the ball part, and the lower end opening of the ball part is made to protrude downward from the rim water drain hole provided at the upper peripheral edge of the Japanese-style toilet. Therefore, even if water splashes back, the splashed waste water will not stick above the rim drain hole, and both the Japanese-style toilet bowl and the seat body can be kept clean at all times, and they will not get dirty like traditional toilets. There is no possibility that it will stick and generate odor.
