Intercepting device for bad smell of drainpipe

The present invention relates to a odor blocking device for blocking the odor flowing back through the sewage pipes, such as kitchen sinks or washrooms.

In the kitchen sink or washroom sewage pipe, a bad smell blocking device is installed to prevent the bad smell from the sewage, infiltration of harmful gas and pests. Most of the bad smell blocking devices use the principle of blocking water using the decayed water with excellent blocking effect. .

This may have some morphological differences depending on the manufacturer or installation location, but in the case of the sink, the sewage pipe is projected from the inner bottom of the connector that is fixed to the bottom of the sink. Protruding the sewer pipe so that a constant amount of water is accumulated around it, and then it is integrated with the strainer from the top or by separating the semicircular odor prevention cap that is separated and configured so that the lower edge of the odor prevention cap is submerged in the deceased person. It is configured to form a barrier film due to the standing person.

Therefore, in the washroom, the odor prevention cap can be installed through the coupling groove formed from the bottom surface. However, in the case of the sink, when the odor prevention cap is installed in the connection pipe connected to the bottom of the sink, the connector is connected to the odor prevention cap. Since the length is longer as the installation space, the space utilization rate of the storage compartment in the bottom of the sink is reduced by that, the space utilization rate of the sink stand is lowered.

In particular, the odor prevention cap is simply combined to maintain a predetermined interval with the sewer pipe on the upper part of the sewage pipe for disintegration, so that a large amount of sewage flows down or the pressure of the harmful gas generated from the sewage pipe or two sinks is connected to the Y-type hose. In the sink, due to the sewage drained from one side sink, the odor prevention cap is easily detached from the drain pipe by the air pressure generated from the hose of the other side, or it is turned over if it is severe. It is being pointed out.

The present invention can increase the space utilization rate of the storage compartment by reducing the length of the connecting pipe at the bottom of the sink when applied to the sink in order to correct the above-mentioned defects, and there is no concern about the loss of function due to the discharge of sewage or gas or air pressure. It is an object of the present invention to provide a odor blocking device for sewage pipes.

In order to achieve the above object, the present invention is to secure the cap coupled to the drain pipe end extending downward from the connecting portion to have a discharge path that can be drained smoothly between the drain pipe and between the lower end of the drain pipe and the upper end of the cap It is characterized in that the cap has a constant amount of sewage to form a blocking film due to the height difference.

1 is an exploded perspective view of the present invention, the present invention is composed of a main body consisting of the connecting portion 2 and the drain pipe 4, and the cap 8 is coupled to the lower end of the drain pipe (4).

The connection part 2 of the main body has a structure in which a coupling groove 9 is formed between the inner and outer support frames, and the coupling groove 9 has a diameter substantially equal to or slightly larger than the diameter of the sewer pipe 10, but preferably inside The support frame extends downwardly and is configured to selectively protrude to form a screw tube 14 on the hook frame 12 in addition to the hook frame 12 when applied to the sink.

The drain pipe 4 of the main body extends downwardly to communicate with the screw pipe 14 from the center of the connecting portion 2, and an end portion of the coupling pipe 16 formed of a male screw is formed.

The cap 8 has an upper open shape, the outer diameter of which is smaller than the inner diameter of the sewer pipe 10, and the inner diameter of the cap 8 that is larger than the outer diameter of the drain pipe 4. Formed longer than the length of the coupling portion 16 is configured to be screwed to the end of the drain pipe (4) of the body.

However, the fixing of the cap 8 to the guide tube 4 of the main body is not limited to screwing, and the structure may be detachably coupled to the main body such as the cap 8 such as the engaging piece and the engaging groove. All are satisfied.

However, the main body and the cap 8 leave the specific coupling means, and the coupling portion 16 of the drain pipe 4 of the main body is formed to be shorter than the length of the coupling piece 18 having the inner lower portion of the cap 8 to engage the main body. A relatively wide drainage passage 20 avoiding the engaging piece 18 between the lower end of the portion 16 and the inner bottom of the cap 8 and between the outer surface of the drain pipe 4 including the engaging portion 16 and the inner surface of the cap 8. To be formed.

Figure 4 shows the application of the present invention to the kitchen sink, the present invention odor blocking device (A) is a part of the sewage pipe connected to the sink 22 and the hose 24 by protruding from the kitchen floor when applied to the sink (10) Inserted into the end.

The sewage pipe 10 partially protruded from the kitchen floor in the coupling groove 9 constituting the connection part 12 by deeply inserting the drain pipe 4 to which the cap 8 is coupled and fixed at the time of installation of the present invention. When the end is forced to be inserted and screwed to the connector 26 having the end of the hose 24 of the sink 22 using the screw pipe 14 protruding to the upper portion of the engaging frame 12 is completed installation.

Therefore, when applied to the kitchen sink is installed in the sewer pipe 10 partially protrudes from the kitchen floor, so that the connecting pipe (28) connected to the outlet bottom of the sink 22 is made to the minimum length to install the strainer Therefore, the length can be reduced, and the storage space provided at the bottom of the sink 22 can be utilized more widely.

In addition, when installed in the sewage pipe of the washroom, the screw pipe (14) having the upper portion of the connecting portion (2) is unnecessary, so to be removed or removed during the manufacturing process, this also inserts the drain pipe with the cap (8) is deeply inserted into the sewer pipe and Installation is completed when forced sewage pipe is inserted into the hang frame.

At this time, the sewage pipe of the washroom has a part of the sewage pipe protruding from the bottom surface of the space part for installing the strainer network, so that it can be easily installed without structural change.

According to the present invention, when the sewage discharged through the drain pipe 4 of the main body reaches the end of the drain pipe 4, the sewage rises along the drainage path 20 between the cap 8 and overflows the cap 8. .

Drainage 20 having between the drain pipe 4 and the cap 8 of the main body during the discharge of sewage is formed relatively wide around the inner surface of the cap 8 so that the drainage is made smoothly without clogging.

In addition, the connection part 2 of the main body is composed of a coupling groove 9 having an inner and outer support frame therebetween, and the end of the sewer pipe 10 is inserted into and fixed to the coupling groove 9 so that sewage through the sewage pipe 10 may be reduced. Backflow is prevented.

At the time of drainage, of course, a certain amount of sewage is constantly accumulated in the drainage path 20 between the drain pipe 4 and the cap 8 of the main body after drainage by the deviation between the lower end of the drain pipe 4 and the upper end of the cap 8. Therefore, the barrier film is formed by the accumulated water.

In addition, when the sewage is configured to overflow between the drain pipe 4 and the cap 8 of the main body, even if the cap 8 is formed long within the range not longer than the length of the drain pipe 4 of the main body, the sewage flow is made smoothly. As a result, the function as a barrier becomes more perfect.

According to the present invention, even if a large amount is discharged at the time of discharge of sewage, the main body is supported by the sewer pipe 10 forcedly inserted into the hook frame 12 and the cap 8 fixed to the drain pipe 4 of the main body is separated from the main body. It can be used with confidence because there is no fear of separation.

In addition, when the sink has two sinks connected to a Y-type hose, when the sewage discharged from one sink is discharged, the hose connecting the other sink generates air pressure or when the pressure is generated by harmful gas inside the sewer pipe. The pressure cannot be strong enough to push out all the sewage accumulated in the cap 8, so that it can faithfully perform its function as a barrier under any adverse conditions that may occur during sewage discharge.

As such, the present invention is installed at the inlet of the sewer pipe 10 so that the sewage flows over the cap 8 coupled to the end of the drain pipe 4 so that a blocking film is formed by the water accumulated in the cap 8. In this case, the length of the connecting pipe 28 connected to the bottom of the sink 22 can be reduced, so that the storage space at the bottom of the sink can be used more widely, and the discharge of sewage or gas pressure from the sewage pipe or air pressure generated from the sewage pipe, etc. There is no fear of functional loss of the barrier film due to the water accumulated in the cap 8 even in external factors.
