Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a bell-shaped drain trap provided at the bottom of a drain device such as a garbage storage device.

General Nibel-type drain traps are widely used because the odor-proofing crown that covers the top of the drain pipe is removable and dirt accumulated in the water seal can be easily cleaned, but this advantage also becomes the biggest disadvantage. ing.

In other words, when the odor-proof crown covering the top of the drain pipe is removed, the water seal formed by the casing is removed.

The foul odor of the sewer pipe and pests rises from the drain pipe, causing 1 inside the house.
There were some drawbacks.

The present invention aims to eliminate such conventional drawbacks, and embodiments thereof will be described below with reference to the drawings.

In the figure, 1 is a bottomed cylindrical drainage device main body, inside which is a garbage lid 2. which opens and closes automatically depending on the weight of water or kitchen waste. A garbage basket 3 for temporarily storing kitchen waste is provided below the garbage lid 2, and a drainage trap 4 is further provided below the garbage basket 3.

5 is a drain pipe that projects upward and downward from the bottom of the drain device main body 1;
The lower end is connected to a sewer pipe 6.

A coil spring 7 is bonded to the outside of the drain pipe 5 and is always biased upward.

8 is a water inlet provided on the side near the upper end of the drain pipe 5; 9 is a coupling-shaped valve body that is closed at the top and opened at the bottom; it has a hole 10 on the side and a hole 10 on the inner wall. An elastic piece 11 made of rubber or the like that is always biased toward the inner wall is provided so as to cover the inner wall.

The coupling-shaped valve body 9 is fitted from the lower open end so as to be placed on the outer circumferential spring γ of the drain tube 5, and the elastic piece 11 is opened from the upper end of the drain tube 5 as shown by a solid line. .

Reference numeral 12 is installed above the coupling-shaped valve body 9, and covers the upper part of the drain tube 5 including the water inlet 8, and connects the drain tube 5.
The deodorizing crown forms a drain pipe 5 and a water seal part A with a drainage interval in between, and has a knob 13 at the center of the upper surface and a strainer part 14 around the periphery.

15 is a cutout part formed in a part of this strainer part 14;
Reference numeral 16 denotes a stopper protruding from a part of the inner wall of the drain main body 1, and the deodorizing crown 12 is placed on the coupling-shaped valve body 9 with the cutout 15 aligned with the stopper 16.

From this state, when the deodorizing crown 12 is pressed against the elastic force of the spring 7, the coupling-shaped valve body 9 is displaced downward, and the perforation 10 of the valve body 9 connects with the water inlet 8 of the drain pipe 5. They match, and drainage channel B is formed.

After that, by rotating the deodorizing crown 12, the upper surface of the strainer portion 14 comes into contact with the lower surface of the stopper 16, and the upward displacement of the deodorizing crown 12 and the coupling-shaped valve body 9 is prevented. There is.

In the above configuration, when cleaning the inside of the drain trap 4 and disposing of trash etc. that have gathered in the strainer part 14, the flameproof layer 1
2 is removed from the drain body 1 by an operation opposite to that described above. At this time, the coupling-shaped valve body 9 is displaced upward by the elastic force of the spring 7, and the drain tube 5 is removed.
The water inlet 8 is closed by a side wall of a coupling-shaped valve body 9.

Further, the perforation 10 of the coupling-shaped valve body 9 is closed by the elastic piece 11, and the drain channel B is closed.

Therefore, it is possible to prevent foul odors, pests, etc. from rising when the water seal portion A is not formed.

In addition, what is shown by the broken line in FIG. 1 is 11 placed on the stopper 16 without placing the flameproof layer 12 on the coupling-shaped valve body 9, and the drainage channel B is closed. The garbage basket 3 is installed inside the drainage device main body 1 to prevent water from being washed away, without realizing that there is water in the drainage device body 1.

In other words, when there is a flameproof layer 12 on the stopper 16, when the garbage basket 3 is installed inside the drain device main body 1, the garbage basket 3
Cart 3 hits the flameproof layer 12.

It is set to be exposed outside the main body 1.

This allows the user to notice that the drain channel B is closed.

Note that the distal end of the drain tube 5 and the distal end of the elastic piece 11 are formed in a tapered shape so that the first elastic piece 11 can be easily pushed out when the coupling-shaped valve body 9 is displaced downward.

In the above embodiment, the valve body is in the shape of a coupling, and the water inlet on the side of the drain tube is opened and closed by moving it up and down. A valve element that is rotatable by a fulcrum may be provided, and the valve element may be rotated so as to be opened by compression when the flameproof layer is attached, and closed by release of the compression when the flameproof layer is removed.

That is, the present invention can be configured in any manner as long as the suppression of the valve body is released as the water seal portion is flattened by removing the flameproof layer, and the valve body is displaced and blocks the drainage portion. However, the present invention is not limited to the structure of the embodiment.

As explained above, in the present invention, when the flameproof layer is removed and the pressure on the valve body is released when the water seal is not formed, the valve body moves to close the water inlet, that is, the drainage channel is closed. This prevents the rise of foul odors and pests from sewage, and the drain that is closed with the valve body is opened in conjunction with the installation of the flameproof layer, eliminating the need to open the drain. be able to.
