Description

[Detailed description of the invention] <Industrial application field> The present invention is a flush toilet device that can be used as a seat type by placing and fixing a seat body on the top surface of an existing flush type Japanese-style toilet. A funnel-shaped ball part facing the saucer part of the Japanese-style toilet is provided on the seat body, which is mounted and fixed so as to cover the existing flush-type Japanese-style toilet, and a mounting hole is drilled in the upper surface outside of this ball part. This item relates to a toilet seat installation screw that is inserted through it and a nut is tightened and fixed from the inner surface of the seat body.

<Prior Art> Conventionally, this type of flush toilet device, as disclosed in Japanese Utility Model Application Publication No. 56-110188, has been constructed by covering an existing Japanese-style toilet with a seat body so that the lower end opening of the ball part can be connected to the rim of the Japanese-style toilet. In some cases, the toilet seat and lid are inserted into the toilet seat body, and the seat and lid are removably attached to the attachment hole on the top surface of the seat body through attachment screws.

<Problem to be solved by the invention> However, in such a conventional flush toilet device, an opening is formed between the lower end opening of the ball part and the front cover side rim of a Japanese-style toilet. In this case, when the user stands and discharges urine toward the front cover from a high position, the dirty water that splashes up at the bottom of the saucer scatters through the opening and adheres to the inner surface of the front cover and its surroundings. This dirt caused by sewage can be cleaned on toilets with a seat body that is easier to remove than Japanese-style toilets, but the seat body is made of ceramic and is heavy, and metal is used to clean the inner surface of the bowl part. When a water supply pipe made of aluminum is connected, the seat body cannot be easily removed and cleaning becomes difficult, resulting in the accumulation of dirt and odor.

In addition, even if you try to replace the toilet seat after the seat body has been placed and fixed, the nut that tightens the toilet seat mounting screw is inside the seat body across the peripheral wall of the ball part, so you will have to rotate the nut from the inside of the ball part. If the seat body cannot be removed as easily as the Japanese-style toilet bowl, as described above, there is a problem in that it takes a long time to replace the toilet seat.

In view of the conventional circumstances, the present invention aims to make it possible to rotate the nut from inside the ball part while preventing sewage from adhering to the inner surface of the front cover part and its surroundings.

<Means for Solving the Problems> The technical means taken by the present invention to solve the above problems is to cut out the lower end of the ball portion on the side of the mounting hole, and attach the inner surface of the front cover of the Japanese-style toilet bowl and the It is characterized by a removable shatterproof cover that covers the periphery.

<Function> According to the above-mentioned technical means, the present invention prevents the waste water that bounces off the bottom of the saucer part and scatters toward the inner surface of the front cover part and its surroundings by the scattering prevention cover, and also prevents the wastewater from scattering by removing the scattering prevention cover. The nut can be reached by hand or with a tool through the notch.

<Example> Hereinafter, an example 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 is shaped to cover the top surface of the Japanese-style toilet A.
A ball part b ₁ facing the saucer part a ₁ of the Japanese-style toilet A is formed in the rear half, and a covering part b ₃ that covers the front cover part a ₂ of the Japanese-style toilet A is formed in the front half through the stepped part b ₂ . do.

In addition, the seat body B has a mounting hole in the upper wall between the ball part b ₁ and the stepped part b ₂ that vertically penetrates the upper wall.

The ball part b ₁ is formed by forming the rim a ₃ of the Japanese-style toilet bowl A into a funnel shape along the rear part, and the lower end opening of the rim a 3 is formed into a funnel shape along the rear part.
_A3 is inserted into the rear part of the rim _A3 , and a sealing member 1 made of rubber or the like and formed into a tubular shape, for example, is interposed between the outer circumferential surface of the opening and the rear part of the rim A3, thereby airtightly sealing the two.

The ball portion b ₁ has an arch-shaped notch at the lower front end so that a hand or a tool can reach the nut 4 fastened to the tip of the mounting screw ₃ from the notch b ₅ . Attach the shatterproof cover 2 to the front.

The scattering prevention cover 2 is made of synthetic resin or the like and has a cross-sectional shape, and its upper surface is in contact with the inner surface of the seat body B, and the tip of the mounting screw 3 is inserted through the nut 4.
While fastening together, the rear end is brought into contact with the sealing member 1 interposed at the rear of the rim _a3 of the Japanese-style toilet A, and the front end is formed in a shape to cover the inner surface of the front cover part _a2 of the Japanese-style toilet A and its surroundings.

Therefore, even if sewage and filth are excreted into the saucer part _A1 of the Japanese-style toilet A, the sewage and filth that bounce off the bottom of the saucer part _A1 are difficult to clean because of the sealing member 1 and the scattering prevention cover 2. There is no scattering on the front covering part _A2 and its surroundings, the inner surface of the seat body B, etc.

In addition, in this embodiment, the nut 4 that fastens the mounting screw 3 can be reached by hand or a tool from the notch _b5 , so that the toilet seat 5 and the lid 6 can be easily attached and detached.

On the other hand, a rim water passage b ₆ is provided at the upper opening edge of the ball part b ₁ over the entire circumference, and the rim water passage b ₆ is formed to protrude inward so as to face the inside of the ball part b ₁ . A large number of water injection holes b ₇ are drilled at appropriate intervals on the lower surface, and a water supply pipe c ₃ communicating with the water supply device C is connected to an appropriate location of the water passage b ₆ .

The water supply device C is a water supply source that supplies water to the so-called flush type Japanese-style toilet A, such as a water storage tank or a flush valve. A branch pipe c ₂ is connected to the tip of the pipe c ₁ , and one end of the branch pipe c ₂ is
A water supply pipe _c3 communicating with the rim water passage _b6 is connected to the other end, and a water pipe _c4 communicating with the Japanese style toilet A is connected to the other end.

The Japanese-style toilet A shown in the drawing is of the so-called flushing type, and has a water supply chamber _A4 at the front end into which a water pipe _C4 is inserted, and the flushing water supplied from the water supply device C to the water supply chamber _A4 . A portion of the water is poured into the toilet bowl A from above the room _A4 .
The remaining washing water is introduced into the front cover part _A2 to wash the inner surface of the front cover part _A2 , and the remaining washing water is passed through the communication hole _A5 drilled on the bottom surface of the water supply chamber _A4 to the rear end of the toilet bowl A through the water channel _A6 .

The waste excreted on the saucer part _A1 by being ejected from the hole _A7 is discharged to the drain part _A8 , and the waste is discharged from the waterway.
From the middle of _A6 , the water flows through the rim communication hole _A9 of the toilet bowl A to the rim injection hole _A10 , and the inner surface of the bowl _A11 of the toilet bowl A is washed. The anti-scattering cover 2 covers the inner surface of the front cover part a ₂ of the Japanese-style toilet bowl A and its surroundings, and the inner surface of the front cover part a ₂ of the Japanese-style toilet bowl A does not have sewage or filth attached to it _. The tip protrudes into the water supply chamber and opens at the inlet of the water supply communication port _A5 to the rim water injection hole _A10 and the injection hole _A7 so that almost no cleaning water flows into the front cover part _A2 .

4 and 5 is another embodiment of the present invention, in which the shatterproof cover 2 is not fixed with the mounting screws 3 and nuts 4, and the shatterproof cover 2 is not fixed with the mounting screws 3 and nuts 4.
It differs from the previous embodiment in that it is attached by locking the collar pieces 7, 7 protruding from the left and right sides of the toilet A to the upper surface of the rim _a3 of the Japanese-style toilet A, and in this case the shatter-prevention cover 2 is made of a flexible material, and the cover 2 is inserted into the seat body B through the notch b ₅ in a bent state, and is attached using the reaction force of the scattering prevention cover 2.

Therefore, this item can be easily taken out by utilizing the flexibility of the scattering prevention cover 2 when attaching/detaching the toilet seat 5 and lid 6 or cleaning.

In addition, in this one, the lower end opening of the ball part _b1 protrudes downward from the rim water injection hole _a10 of the Japanese-style toilet A, so that splashes of sewage and filth do not adhere above the rim water injection hole _a10 . It is always clean and washable.

FIG. 6 shows yet another embodiment, in which a scattering prevention cover 2 made of a sheet-like material such as rubber is fixed so as to cover the notch _b5 of the ball part _b1 . The lower end of the cover 2 extends as far downward as possible and has an appropriate curtain-shaped cut. By doing this, sewage will not be scattered to the front cover part _a2 side, and even if the inside becomes dirty, cleaning will be easy, and the toilet seat 5 etc. will be easy to replace.

In each of the above embodiments, a type in which the Japanese-style toilet bowl A is provided on a stepped floor surface D is shown, but the present invention is not limited to this, and a type in which the Japanese-style toilet bowl A is provided on a flat floor surface D is shown. Needless to say, the Japanese-style toilet A is not limited to the flush type, but may be of other types. Further, although the water supply to the stool body B is branched from the secondary side of the water supply device C, the present invention is not limited to this, and water may be supplied in any manner, such as providing a separate water supply device exclusively for the stool body B.

<Effects of the Invention> Since the present invention has the above configuration, it has the following advantages.

Sewage that bounces off the bottom of the saucer and scatters toward the inner surface of the front cover and its surroundings is blocked by the scattering prevention cover, and by removing the scattering prevention cover, hands or tools can reach the nut through the notch, so the front cover The nut can be rotated from inside the ball part while preventing sewage from adhering to the inner surface and its surroundings.

Therefore, even if the seat body cannot be removed as easily as in a Japanese-style toilet bowl, the inner surface of the front cover and its surroundings can be kept clean, no odor is generated, and the toilet seat can be easily replaced.
