Description

[Detailed explanation of the idea] (1) Industrial application field The present invention relates to a drainage trap.

(2) Problems to be solved by conventional techniques and ideas Conventional drainage traps include a connecting pipe inside an outer cylinder that penetrates through the bottom of the outer cylinder and is fixed to the bottom of the outer cylinder, and a connecting pipe that covers the connecting pipe. There was a type of pipe that consisted of a bowl set up in such a way that the water level always reached the top of the connecting pipe to form a water seal, but this had the disadvantage that drainage was difficult to flow and dirt easily clogged. This idea is
The object of the present invention is to provide a drainage trap that solves the above-mentioned drawbacks.

(3) Means for Solving the Problem As shown in Figs. 1 to 5, the drain trap of the present invention has a tray lid 5 that can store water at the lower end opening 321 of the drain pipe 3, and is capable of storing water under a constant load. Tighten the lid using the force of the spring 6 until the lid 5
When the load exceeds a certain level, the lid can be opened against the force of the spring 6.

(4) Example The first example is as shown in Figures 1 to 5.
It consists of an outer cylinder 1, a strainer 2, a drainage pipe 3, a packing 4, a tray-shaped lid 5, and a spring 6.

The outer cylinder 1 is provided with a plurality of pawls 121 on the flange 12 of the upper opening, and on the inner circumferential surface immediately below the pawls 121.
A groove 11 surrounding this is provided, and the opening at the lower end is connected to the drain connection pipe 7. The strainer 2 has a large number of slits 22 formed therein. The drain pipe 3 consists of a flange 31 and a cylindrical portion 32. Notches 211 and 311 are provided in the outer circumferential ring portion 21 of the strainer 2 and the flange 31 of the drain pipe 3 at positions corresponding to the pawls 121, respectively. The packing 4 includes the flange 31
and the bottom surface 111 of the groove 11.

The tray-shaped lid 5 rotates about a rotation shaft 53 supported by a bearing 14 in the outer cylinder 1, and has a collar 51 on its outer periphery so as to be able to collect water, and has an annular packing 52 on its inner periphery. installed. Spring 6
is a tension cylindrical coil spring whose one end is attached to the spring attachment piece 54 of the lid 5 and the other end is attached to the spring attachment 15 of the outer cylinder 1. Note that 13 is an opening/closing buffer for the lid 5, which is provided at the lower part of the outer cylinder 1.

In the second embodiment, as shown in FIG.
A spring mounting piece 54A for attaching the lid 5A is rotatably fitted to the center of a rotating shaft 53A supported by a bearing 14A provided in the outer cylinder 1A, and torsion coil springs 6A are fitted on both sides of the spring mounting piece 54A. One end of the torsion coil spring 6A is attached to the mounting piece 54A, and the other end is attached to the inner surface of the outer cylinder 1. The rest of the configuration of this example is the same as that of the first example, so a description thereof will be omitted.

(4) Functions and Effects In the drain trap of the present invention, when a large amount of waste water flows from the strainer 2 onto the tray-shaped lid 5 of the drain pipe 3, the force of the spring 6 supporting the lid 5 can resist the weight of the water. When the liquid runs out, the lid 5 opens and the liquid flows down into the connecting pipe 7. When the amount of drainage decreases, the force of the spring 6 supporting the lid 5 is overcome, and the lid 5 seals the lower end opening 321 of the cylindrical portion 32 of the drainage pipe 3. Therefore, the drainage water accumulates in the cylindrical portion 32 of the drainage pipe 3 and is sealed with water, so that the deodorizing effect is perfected. Even if there is no standing water on the lid 5, the lower end opening 321 of the drain pipe 3
Since the lid is tightened, it goes without saying that it has a deodorizing effect.

The present invention has a simple structure, so it can be manufactured at low cost, and it can be easily disassembled and repaired.Drainage flows well, so there is little risk of clogging with garbage.
