The present invention relates to a drainage drainage applied to a home drain, a sewer manhole, and more particularly, a home drainage pipe, a odor blocking for drainage to facilitate drainage of odors while easily blocking the odor flowing back from the sewer. Relates to a device.

Sewage generated in homes, restaurants, etc. flows out through the drain pipes and flows along the sewer. Since dirt is inside the drain pipes, odors flow back into the household drains and enter the room. Odor also flows out through the sewer manhole (hereinafter referred to as drain).

So conventionally, in order to block the odor by dirt as described above, for example, the domestic drain is formed in the structure of disposing the ball in the interior of the main body is formed concave, the lower side as filed in Patent Application No. 10-2001-77150 have.

The drainage hole formed as described above blocks the inner lower part of the body in the state where the water does not flow from the upper part to completely block the odor flowing from the bottom of the body, and when the water flows from the upper side, the floating ball rises to buoyancy. By opening the inner lower portion of the body to discharge the water down.

However, in the related art, the odor flowing from the bottom can be completely removed by completely blocking the inner lower part of the main body with a knitting ball. However, when water flows in from the upper part of the main body, the water flows in the part where the circumferential surface of the main body and the inner side of the main body come into contact with each other. This is very fast and the pressure is sharply lowered so that the float ball does not rise by buoyancy, but the float ball comes into contact with the inner surface of the main body, which hinders the drainage of dirt.

On the other hand, in order to prevent the backflow of sewage odor, sedimentation tanks and sewers having a backflow prevention function, which are sewage manholes, have been filed as a patent application No. 10-2000-10977, which has a center of gravity inside the body to block odors. Opening and closing plate opening and closing using the structure is formed.

The drain is made of water in the main body of the body when the water is built in the opening and closing plate open due to the weight of the water, when the water drained down the center of gravity of the opening and closing plate to return to the initial state of the opening and closing plate to block the inside of the main body do.

However, such a conventional drain is a simple structure, but because the opening and closing plate is rotated when foreign matter flows in the center of rotation hinders the rotation, the opening and closing plate is not closed properly, there is a disadvantage that the odor can flow through the gap.

The present invention has been made to solve the problems of the prior art as described above, the object of the present invention is to adjust the drainage in accordance with the inflow amount flowing into the drain, and also to block the backflow of odor elastically for household drainage pipes and sewerage The present invention relates to a drainage device that can easily drain odors and easily block odors flowing back from the plant.

In order to realize this, the present invention is provided in the drain hole to drain the external sewage by hanging the drain top plate and the drain body on the frame, a plurality of inlet is formed at the top and the outlet for a small amount of drainage at the bottom A blocking member which is formed to intercept a drain hole formed at the lower side of the drainage body, is installed at an outlet of the blocking member to prevent odor backflow from the outlet of the blocking member, and elastically supports the lower side of the blocking member. Provided is a pleated pipe-like synthetic resin elastic body, a odor blocking device for drains comprising a support member inserted into the central portion of the drainage upper plate and a guide member for penetrating the blocking member and the pleated pipe to support the lower side of the synthetic resin elastic body.

Hereinafter, preferred embodiments of the present invention will be described in more detail with reference to the accompanying drawings.

1 and 2 is a view showing the odor blocking device for the drain according to the present invention, the drain 1 can be installed on the domestic drain pipe (not shown) or the sewer, as in the prior art, on the frame 11 The drainage upper plate 12 having a plurality of through holes 12a and the drainage main body 13 are disposed in the structure to induce the external sewage to flow downward.

In addition, in the odor blocking device for drainage according to the present invention, the blocking member 21 intercepts the drain hole 13a formed at the lower side of the drainage main body 13, and the odor countercurrent blocking is disposed below the blocking member 21. Means are provided, the synthetic resin elastic body 22 of the pleated pipe shape elastically supports the lower side of the blocking member 21, the guide member 23 supports the lower portion thereof to prevent the synthetic resin elastic body 22 from being separated It is made of a structure.

Here, the blocking member 21 has a space for temporarily storing sewage, etc., and a plurality of inlets 21a for introducing a large amount of sewage are formed at an upper portion thereof, and an outlet 21b for a small amount of drainage at the lower side thereof. ) Is formed.

The cross-sectional area of the inlet 21a of the blocking member 21 is formed to be larger than the cross-sectional area of the outlet 21b so that the amount of sewage flowing in from the inlet 21a is larger than the outflow amount flowing out of the outlet 21b.

Of course, the blocking member 21 may be manufactured in one mold, but may be formed by assembling and simplifying the structure or manufacturing a plurality.

The malodor counterflow blocking means is installed at the outlet 21b of the blocking member 21 to prevent the backflow of the malodor from the outlet 21b of the blocking member 21. As an example, as shown in FIG. N-shaped small diameter bending pipe 24 is configured in a simple shape.

In addition, the malodor backflow blocking means as shown in FIGS. 2 and 3 as another example, the small diameter pipe 25 is fixed to the outlet of the blocking member 21, one side of the lower end of the small diameter pipe 25 It is rotatably installed in the opening and closing of the lower end of the small diameter pipe 25 and the center of gravity is formed of the opening and closing plate 26 formed on the outside.

In other words, the opening and closing plate 26 does not form a center of gravity at a portion of opening and closing the small diameter pipe 25 so as to always have a rotational force to close the small diameter pipe 25, and forms a center of gravity at the outside.

Of course, the small diameter pipe 25 may be integrally formed at the outlet 21b of the blocking member 21.

The synthetic resin elastomer 22 has a restoring force while being formed in a pleated pipe shape, and is formed of a synthetic resin material so as not to corrode for a long time.

In addition, when the elasticity of the synthetic resin elastomer 22 due to the weight of the blocking member 21 itself, as shown in Figure 4, the present invention is disposed inside the synthetic resin elastic body 22 and the It is installed on the lower circumferential surface of the guide member 23 includes a spring 22b for additionally elastically supporting the lower side of the blocking member 21.

Of course, since the upper end and the lower end of the synthetic resin elastomer 22 are formed in a conventional manner, the air is formed in a structure that allows air to flow, but the upper part as shown in FIG. 3 in order to smoothly distribute the air or discharge the water introduced therein. Holes 22a can be formed in and below.

The guide member 23 is inserted into the central portion of the drainage upper plate 12 to be locked, and passes through the blocking member 21 and the synthetic resin elastomer 22 to support the lower side of the synthetic resin elastomer 22.

Meanwhile, in the present invention, as shown in FIG. 5 to adjust the elastic force of the synthetic resin elastic body 22, a male screw portion 23a is formed at the lower end of the guide member 23, and the number of the guide members 23 is reduced. The adjusting nut 23b is fastened to the threaded portion 23a to support the lower portion of the synthetic resin elastic body 22 by the adjusting nut 23b, and according to the position of the adjusting nut 23b. The elastic force is variable by compressing or stretching (22).

As another example, the present invention, as shown in Figure 6, the female screw portion (23c) is formed on the upper end of the guide member 23, and the adjustment bolt 23d is inserted into the central portion of the drainage upper plate 12 It includes a structure that is fastened to the female screw portion (23c) of the guide member (23).

The odor blocking device for drainage outlets according to the present invention thus formed acts as follows.

First, as shown in FIG. 7, when a small amount of sewage flows into the through hole 12a of the drainage upper plate 12, the sewage flows into the blocking member 21 through the inlet 21a of the blocking member 21. Then, the sewage introduced into the blocking member 21 flows out to the outlet 21b of the blocking member 21 to open the odor countercurrent blocking means, that is, the opening and closing plate 26 in the drawing and flows downward.

In order to discharge a small amount of sewage, it is possible to configure only the blocking member 21 and the malodor counterflow blocking means. However, when a large amount of sewage flows into the through hole 12a of the drain top plate 12, as shown in FIG. Since a large amount of sewage is built into the blocking member 21, the synthetic resin elastomer 22 does not support the blocking member 21 in an initial state, and thus the blocking member 21 moves downward.

Then, a large amount of waste water flows down through the drain hole 13a of the drain body 13 opened due to the movement of the blocking member 21 in a large amount.

Thus, a large amount of sewage can be smoothly drained.

Finally, when there is no inflow of sewage into the through hole 12a of the drainage upper plate 12, as shown in FIG. 9, the sewage built into the blocking member 21 is discharged to the outlet of the blocking member 21, and thus the blocking member. (21) is gradually raised to block the drain hole (13a) of the drainage main body 13, the sewage in the blocking member 21 can be completely discharged to the outlet (21b) of the blocking member 21, completely discharged Afterwards, as shown in FIG. 2, the odor flowing back is completely blocked.

As described above, the odor blocking device for drainage according to the present invention is easy to discharge the sewage because the blocking member is moved up and down according to the inflow amount of the sewage flowing into the drainage, the drainage is automatically adjusted, and the sewage is completely discharged. Since the upper and lower sides are completely sealed by the blocking member and the odor counter flow blocking means, there is an advantage that the odor flowing back from the domestic drain pipe and the sewer can be easily blocked.
