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. If cleaning is neglected, clogging may occur and there is a risk of 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.

Also, between the opposing side walls 3b of the trap body 3 is a partition wall 3C.
is constructed vertically from near the upper end of the support wall 13 to a position L' below the normal water level, and is connected to the connection part 9 in a U-shape while ensuring a predetermined water sealing depth (distance between L and L'). A flow path 14 is formed.

Note that the partition wall 3C may be installed by providing vertical engagement grooves in the side wall 3b and being engaged with these grooves, inserted from above, and then removed.

On the upper side wall of the trap body 3, a lid 15 with an edge that fits into the gasket fitting groove 12 is fixed by fitting the edge 15a into the gasket fitting groove and pressing against the gasket 16 in the bottom of the groove. The upper opening of the trap body 3 is covered by a lid 15.

In this case, a flat plate 17 with screw holes is embedded in the support wall 13, and by passing the lid 15 through the screw hole and screwing in the screws 18, 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.

The lid portion located on the inlet side of the flow path 14 has a perforated plate 19.
is removably provided.

A gasket mounting groove 20 that loosely fits into the upper end of the partition wall 3C is provided on the back surface of the lid 15 by, for example, providing two protrusions 21 with an L-shaped cross section, and a gasket with a groove-shaped cross section is provided inside the groove. 22 is attached, and by fixing the lid 15, the upper end of the partition wall is inserted into the gasket 22 as shown in FIG. 3, thereby performing a seal between the partition wall and the lid.

In the above configuration, when the trap portion becomes clogged, if removing the perforated plate 19 is not enough, the lid 15 is removed from the trap body 3 and the inside of the trap body 3 is cleaned.

In this case, since there is no protruding object from the drain pipe 8 side, and both sides of the partition wall 3c are open, it is easy to clean, and therefore, clogging of the trap portion can be easily cleared.

Furthermore, if the lid 15 is fixed to the trap body 3 and the waste water is allowed to flow through the perforated plate 19, the waste water will stay up to the normal water level, so the outlet side of the flow path 14 will be connected to the lid part and the partition wall 3C on the same side as the accumulated waste water. This seals the drain pipe 8 and ensures a trapping effect that blocks odors and the like from the drain pipe 8.

As mentioned above, this device can be assembled and exert its trap effect by simply putting a lid on the trap body, and has a simple structure that allows for easy cleaning by removing the lid, so even if the trap part becomes clogged, it can be quickly removed. This can be resolved and flooding accidents can be eliminated.
