Description

[Detailed Description of the Invention] This invention relates to a drain trap that is installed and used at the drain outlet of a sink, bathroom, etc.

Traditionally, this type of drainage trap has been equipped with an S-shaped or U-shaped part in a part of the drain pipe, in which part of the wastewater always remains, and a drum with an opening at the top as a drainage outlet. The inlet end of the drain pipe is inserted into the bottom of the container, and a cap is provided around the inner end of the container to form a U-shaped flow path, so that a portion of the wastewater always remains in the flow path. Things to keep are known.

However, since the trap part is narrow in both cases, it is easily clogged when various rubber, paper scraps, sand, mud, etc. flow into the trap part, and the cleaning opening is extremely small, making cleaning difficult. They tend to be poorly managed, and if cleaning is neglected, they can quickly become clogged and cause flooding.

This invention was devised to solve the above-mentioned conventional problems, and its purpose is to provide a trap structure that allows the trap portion to be cleaned easily, quickly, and reliably.

Hereinafter, this invention will be explained with reference to an illustrated embodiment. For example, a sink body 1 made of fiber-reinforced plastic has a stepped part 2 in the circumferential direction at the lower part of the inner wall by integral molding, and an opening at the upper part in the bottom wall. It is equipped with a box-shaped trap body 3, and a wire mesh 4 for removing coarse waste is removably disposed inside the sink body, supported by a stepped portion 2.

The sink body 1 is supported by a support structure 5 fitted between the outer walls and a pedestal 6 having the support structure 5 around the upper part.

Reference numeral 7 designates aprons provided on three sides of the pedestal 6, including the side and rear surfaces.

The trap main body 3 has a drain pipe 8 on one side wall 3a of the main body part that protrudes into the frame 6 surrounded by the apron 7 in this way.
The water surface is provided with a connecting portion 9, which determines the normal water surface position.

Further, an outward facing collar 10 is provided on the upper side wall of the trap body 3, a connecting wall 11 is provided on the outer peripheral edge of the collar 10, and a gasket mounting groove 12 is provided on the inner peripheral edge of the trap body 3, lower than the vertical wall.
Support walls 13 forming the trap body 1 are arranged in parallel and protrude perpendicularly to the collar surface, and the trap body 3 is connected to the bottom wall of the sink body 1 at the upper end of the connecting wall 11.

On the upper side wall of the trap body 3, a lid 14 with an edge that fits into the gasket fitting groove 12 is fixed by fitting the edge 14a into the gasket fitting groove and pressing against the gasket 15 in the bottom of the groove. The upper opening of the trap body 3 is covered by the lid 14.

In this case, a flat plate 16 with screw holes is embedded in the support wall 13, and by passing the lid 14 through the screw hole and screwing in the screws 17, the lid is removably fixed to the trap body 3, and the lid surface is It almost coincides with the bottom wall surface of the sink body 1.

A partition plate 18 is protruded from the back surface of the lid 14, and when the lid is fixed, it is vertically inserted into the trap body 3 to a position L' lower than the normal water level, and a predetermined water sealing depth L is established. A U-shaped flow path 19 is formed that continues to the connecting portion 9 while ensuring a distance between L' and L'.

In addition, a perforated plate 2 is provided on the lid portion located on the inlet side of this flow path 19.
0 is not shown but is provided in a removable manner.

In the above configuration, if the trap part becomes clogged, if removing the perforated plate 20 is not enough, remove the partition wall 18 together with the lid 14 from the trap body 3 and clean it outside the trap body 3, and clean the inside of the trap body 3. You can also clean it.

In this case, the interior of the trap body 3 is easy to clean because the partition wall 18 that would be an obstacle to cleaning has been removed, so that clogging in the trap portion can be easily cleared.

Furthermore, if the lid 14 is fixed to the trap body 3 and the waste water flows in through the perforated plate 20, the waste water will stay up to the normal water level, so the outlet side of the flow path 19 will be connected to the lid part on the same side as the accumulated waste water. It is sealed with the partition plate 18, and a trap effect of blocking odor etc. from the drain pipe 8 can be ensured.

In this embodiment, a partition plate 18 is provided on the side wall of the trap body 3.
However, if a sealing material is provided on at least one side, a sealing effect can be reliably obtained and the trapping effect can be made more reliable.

As mentioned above, this device not only can be assembled to exert its trap effect by simply fixing the lid to the trap body, but also has a simple structure that can be disassembled by removing the lid and cleaned very easily and quickly. Even if a blockage occurs, it can be cleared immediately, flooding accidents can be eliminated, and the structure can be downsized without any problems.
