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.

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

This type of toilet bowl cleaning tank can be applied to a tank with a hand wash, and has a nozzle installed in the seat body to spray water onto the inner surface of the ball part, and a ball tap water inlet that supplies water directly into the tank. By connecting either of the water inlets that supply water into the tank through the hand washing pipe, water is released for Japanese-style toilet flushing, and while the ball tap opens and supplies water to the tank, a portion of the water is allowed to flow through the nozzle. The purpose is to supply water to the seat body and clean its inner wall surface.

Normally, the time required to supply water to the tank is around 1 minute, but in the conventional system mentioned above, a portion of the water is sent to the simple toilet seat body, so the time required to supply water to the tank is further extended, and during that time the amount of water discharged to the seat body is reduced. It will be very large. Therefore, if you want to save water, you have to narrow down the flow path to the stool body, but if you do that, the flow rate per hour will be small and there will be no water pressure, so the inner wall surface of the stool body cannot be cleaned evenly. There is a problem.

Therefore, the object of the present invention is to reliably clean the inner wall of the stool body and to save water.

In general, the inner wall of the stool body is easily soiled by the scattering of dirty water and filth, and it is necessary to run cleaning water to wash away this. Water must flow at an instantaneous flow rate. Furthermore, when used for defecating, a large amount of washing water must be flushed toward the Japanese-style toilet in order to wash away the filth in the toilet tray, but when urinating, it is necessary to flush the inner wall of the seat. If enough flushing water is flushed, the Japanese-style toilet bowl will also be flushed at the same time, and water can be saved by changing the water supply method for defecating and urinating.

Therefore, the technical means taken by the present invention to achieve the above object is to install a branch stopper in the primary water supply pipe of the water supply device of the existing Japanese-style toilet, connect the branch water supply pipe to the seat body, and then connect the branch water supply pipe to the seat body. By installing a second water supply device in the middle of the pipe, it is possible to independently supply water to the seat body.

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

In this embodiment, as shown in Fig. 1, a flush Japanese-style toilet A is installed on a stepped floor D, and can also be used for men's errands. B is placed on 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. 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 A, and its lower end opening edge is inserted into the rear rim 6, and the ball part 2 protrudes downward from the water injection hole 7 of the rim 6, and its upper end opening edge is inserted into the rear rim 6. A rim passageway 8 is provided around the entire circumference.

The rim water passage 8 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 9 are bored at appropriate intervals on the lower surface of the rim water passage 8. A branch water supply pipe 11 branched from the upstream water supply pipe 10 of the water supply device C for the existing Japanese-style toilet A is connected to an appropriate location.

In addition, the seat body B has a toilet seat 12 on the upper surface of the middle part and a lid 13 rotatably attached above it as needed, and a pedestal 14 protruding from the lower end of the outer periphery.
This pedestal 14 is fixed to the floor surface D using screws 15 or the like.

The water supply device C is a device for supplying flush water to the existing flush-type Japanese-style toilet A, and generally consists of a so-called toilet bowl cleaning tank equipped with a ball tap and a drain valve, and a flush valve installed in the middle of the water supply pipe. There is.

In the embodiment shown in FIGS. 1 to 3, the water supply device C is a toilet cleaning tank, and a water supply pipe 10 serving as a water supply source is connected to the primary side of the ball tap, and a cleaning pipe 16 is connected to the secondary side of the drain valve. A Japanese-style toilet bowl A is connected through the toilet.

On the other hand, a branch water supply pipe 11 connected to the rim water passage 8 of the seat body B has a branch stopper 1 in the middle of the water supply pipe 10 connected to the ball tap of the toilet cleaning tank C.
7 is provided, and a second valve consisting of a small-capacity flush valve is installed in the middle.
A water supply device E is provided.

Therefore, by operating the second water supply device E, water can be supplied to the seat body B independently from the water supply from the cleaning tank C to the Japanese-style toilet bowl A.

Therefore, when urinating, it can be washed by operating the flush valve E, which is the second water supply device, and when urinating, the filth can be removed by operating the operating handle 18 of the washing tank C. Washing by flushing becomes possible. At this time, if necessary, by operating the flush valve E at the same time,
Dirt and dirt attached to the stool body B can be washed away.

The Japanese-style toilet A shown in the drawing is of the so-called flushing type, and a water supply chamber 19 into which the cleaning pipe 16 of the toilet cleaning tank C is inserted is formed at the front end.
A part of the washing water supplied to this water supply chamber 19 from above through the washing pipe 16 is guided from above the chamber 19 to the front cover part 4 of the toilet bowl A to wash the inner surface of the front cover part 4, and the remaining wash water is A communication hole 20 is drilled in the lower surface of the water supply chamber 19.
The filth that has been excreted on the tray portion 1 is discharged from the hole 22 through the water channel 21 to the spout hole 22 formed at the rear end of the toilet bowl A, and the waste excreted on the tray portion 1 is flushed out to the drain port portion 23. A rim communication hole 2
4 to the rim injection hole 7 to clean the inner surface of the bowl 25 of the toilet bowl A. In this embodiment, the opening at the lower end of the ball portion 2 of the seat body B is similar to that of the Japanese style toilet bowl A. The covering part 5 of the seat body B covers the front covering part 4 of the Japanese-style toilet bowl A, and the front covering part 4 of the Japanese-style toilet bowl is free from the adhesion of sewage and filth. Therefore, the tip of the cleaning pipe 16 is projected to the inside of the water supply chamber 19 and opened at the inlet of the water supply communication port 20 to the rim water injection hole 7 and the jet hole 22, so that almost no cleaning water flows into the front cover part 4.

With this structure, the water level of the cleaning tank C can be adjusted to reduce the amount of water discharged into the Japanese-style toilet bowl A. Therefore, even if water is spouted from the cleaning tank C and the flush valve E at the same time during defecation, the total amount will not increase much.

In general, people defecate about once a day, and urinate about 4 times a day.
Although it is said that 6 times, women always use the toilet, and the effect of using a small amount of water when urinating is significant. Of course, this effect is even greater in the case of boys' large and small toilets.

Next, FIG. 4 shows another embodiment of the present invention, which differs from the previous embodiment in that the water supply device C is constituted by a flush valve, and the second water supply device The branch water supply pipe 11 provided with E is branched from the water supply pipe 10 by a branch stopper 17 on the primary side of the flush valve C, and is connected to the seat body B.

In both of the above embodiments, the flushing type toilet bowl A is described, but the Japanese style toilet bowl A is not limited to this and may be of other types. In this case, the structure of the Japanese style toilet bowl Depending on the branch water supply pipe 11
may be piped outside the stool body B, passing through the side and top surfaces of the stool body B, and being connected to the rim water passageway 8.

In addition, the existing Japanese-style toilet A is not limited to one installed on a stepped floor surface D, but may of course be installed on a flat floor surface.

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

A branch water supply pipe is taken out from the primary water supply pipe of the existing Japanese-style toilet water supply system, and this is connected to the seat body, and a second water supply device is installed in the middle of the branch water supply pipe to independently supply water to the seat body. Therefore, while water is being supplied to the tank, part of the supplied water is used to clean the stool body.In order to save water, it is necessary to narrow down the flow path to the stool body. Unlike the
Water can be reliably flowed to the seat body at an instantaneous flow rate of a certain level or more, and the seat body can be reliably washed.

It is not necessary to flush a large amount of water toward the Japanese-style toilet side when urinating, and only enough flushing water to clean the inner wall surface of the seat body can be flushed through the second water supply device, so that a large amount of water can be saved.
