Description

[Detailed Description of the Invention] "Industrial Application Field" The present invention relates to a modified Western-style toilet that can be converted into a Western-style toilet without removing an existing dual-purpose Japanese-style toilet.

"Prior Art" FIG. 1 is a side view showing a conventional modified Western-style toilet 2 attached to an existing dual-use Japanese-style toilet 1.
FIG. 2 is a side sectional view of the main part thereof.

The modified Western-style toilet bowl 2 is placed on the existing dual-purpose Japanese-style toilet bowl 1 and fixed to the floor surface 3 with wood screws 4 or the like. Reference numeral 5 denotes a washing pipe for supplying washing water to the modified Western-style toilet bowl 2, which is branched and connected to the existing dual-purpose Japanese-style toilet bowl 1 from a washing pipe 7 that supplies washing water from a low tank 6. Approximately 65% of the cleaning water discharged from the low tank 6 is used to clean the modified Western-style toilet 5, and the remaining 35%
Wash the dual-use Japanese-style toilet bowl 1. Modified western style toilet 2
The flushing water falls onto the bowl surface 10 of the dual-purpose Japanese-style toilet 1 through the bottom opening 9, which is approximately the same shape as the bowl 8 of the dual-purpose Japanese-style toilet 1 and is slightly smaller than the bowl 8, and the flushing water falls onto the bowl surface 10 of the dual-purpose Japanese-style toilet 1.
It merges with the washing water.

"Problems to be Solved by the Invention" As shown in FIG. 2, the modified Western-style toilet 2 has a bottom opening 9 that approximately matches the shape of the bowl 8 of the dual-use Japanese-style toilet 1 and is slightly smaller than the bowl 8. Since the structure is such that filth and washing water fall directly from the bottom opening 9 onto the bowl surface 10 of the dual-use Japanese-style toilet 1, it has the following drawbacks.

Modified Western-style toilet 2 with falling filth and washing water scattering
In such a case, even if the cleaning operation is repeated, it is impossible to clean that part, causing the emission of odors.

When sitting on the modified Western-style toilet 2, the distance from the seat to the top surface of the bowl 8 of the dual-use Japanese-style toilet 1 is about 300 mm, so there is a risk that filth may bounce off when it falls.

The amount of flushing water supplied to the modified Western-style toilet bowl 2 is less than 2 liters, so the modified Western-style toilet bowl 2 may be damaged due to poor cleaning.
Dirt may remain.

The filth falls directly onto the top surface of the bowl of a dual-purpose Japanese style toilet, but since there is only accumulated water at a depth of about 1 to 2 cm on the top surface of the bowl, the filth is inevitably exposed from the water surface and odors are emitted.

"Purpose of the invention" The present invention was devised in view of the above-mentioned circumstances, and is a modified Western-style toilet that can be converted into a Western-style toilet without removing the existing dual-purpose Japanese-style toilet. By providing a drain opening on the secondary side of the water storage part directly above the water collection part that is open to the atmosphere of the existing dual-use Japanese-style toilet via a trap, the waste water can be temporarily removed from the water collection part. After storing the water, the cleaning water is supplied to both the existing dual-use Japanese-style toilet and the modified Western-style toilet, and the filth and cleaning water are discharged from the storage part of the dual-use Japanese-style toilet to the outside of the system without scattering through the drain port. It is something to do.

``Structure of the invention'' (Means for solving the problem) A water reservoir is provided, and the secondary side of the water reservoir is provided with a trap that is approximately aligned with the water reservoir that is open to the atmosphere in the existing dual-use Japanese style toilet. A drain opening will be provided directly above the toilet to allow flushing water to flow into both the existing dual-purpose Japanese-style toilet and the modified Western-style toilet.

(Function) Since the water reservoir is provided, the fallen filth is submerged in the water reservoir, and there is no risk of odors being released. When sitting on a modified Western-style toilet, the distance from the seat to the water surface of the modified Western-style toilet is approximately 200mm high.
There is no risk of filth bouncing back (commonly known as splatter) when it falls. In addition, the drain of the modified Western-style toilet is open to the atmosphere, so sewage and filth can flow easily inside the trap.

Since a drain opening is provided directly above the water storage part of the existing dual-purpose Japanese-style toilet, filth and sewage are discharged out of the system of the dual-purpose Japanese-style toilet without scattering. In addition, since flushing water flows through the dual-purpose Japanese-style toilet, the interior of the dual-purpose Japanese-style toilet can be kept clean.

(Example) The present invention will be described below based on drawings showing examples thereof.

FIG. 3 is a side sectional view of a main part showing a state in which the modified Western-style toilet according to the present invention is attached to an existing dual-purpose Japanese-style toilet.

The modified Western-style toilet bowl 11 according to the present invention is placed on an existing dual-purpose Japanese-style toilet bowl 12, and then fixed to the floor using wood screws or the like as in the conventional method, although not shown. 13
is a water supply port of the modified Western-style toilet 11, and a cleaning pipe 14, which was connected to the existing dual-purpose Japanese-style toilet 12 for water supply, is connected to the water supply port 13. Directly below the water supply port 13, a water supply introduction branch chamber 16 is formed in a wall 15, and the modified Western-style toilet 11 is connected to the modified Western-style toilet 11 through a hole 17 formed in the wall 15, and the existing Washing water is supplied to the dual-use Japanese-style toilet bowl 12 from a water supply introduction branch chamber 16, respectively. In this embodiment, the branch conduit 19 is constructed as a separate structure, but there is no problem even if the branch pipe 19 is constructed integrally with the modified Western-style toilet bowl 11. The proportion of flushing water supplied from the water supply introduction branch room 16 to both toilet bowls is 65% to the modified Western-style toilet 11 and 35% to the existing dual-purpose Japanese-style toilet 12. The flushing water supplied to the modified Western-style toilet bowl 11 from the hole 17 flows through the rim passageway 2.
0 to clean the inside of the pot 21. A water reservoir 22 is formed on the bottom of the bowl 21, and a trap 23 is provided on the secondary side of the water reservoir 22 to directly above the water reservoir 24 of the existing dual-use Japanese-style toilet 12 at a position that substantially coincides with the water reservoir 22. A drain port 25 opens downward.

"Effects of the Invention" As is clear from the above explanation, in the case of the modified Western-style toilet according to the present invention, a water storage part is provided, and the existing dual-use Japanese-style toilet is connected to the existing dual-use Japanese-style toilet via a trap on the secondary side of the water storage part. A drain outlet is provided that opens directly above the water storage section that is open to the atmosphere, and flushing water flows into both the existing dual-purpose Japanese-style toilet bowl and the modified Western-style toilet bowl, resulting in the following effects.

Since the water storage part is provided, the fallen waste is submerged in the water storage part, and there is no risk of odors being released. When sitting on a modified Western-style toilet, the distance from the seat to the water surface of the modified Western-style toilet is approximately 200mm high.
There is no splashing (commonly known as otsuri) when filth falls. The lower part of the drain of the modified Western-style toilet is open to the atmosphere, so sewage and filth can flow easily inside the trap.

Since a drain opening is provided directly above the water storage part of the existing dual-purpose Japanese-style toilet, filth and sewage are discharged out of the system of the dual-purpose Japanese-style toilet without scattering. Cleaning water also flows through the dual-use Japanese-style toilet, so the interior of the dual-use Japanese-style toilet can be kept clean.

Although it is a modified Western-style toilet, it provides the same comfortable feeling of use as a Western-style toilet.
