DRAINAGE VALVE FOR SINK}

This paper relates to the drainage of the sink. Especially, it has a lid that inserts a connector into a sink hose connected to the sink and fastens it with a fastener, and a rubber sponge is mounted on a seat formed at the outer periphery of the connector inside the lid. The upper part is fastened to the lid so as to contact the packing inserted into the insertion part outside the seating part where the rubber sponge is seated, and the lower part is provided with a drain container connecting the drain hose to the inside of the drain container. It is raised by the pressure of the water flowing back from the drain hose and close to the inner diameter of the rubber sponge inside the lid, and it is equipped with a flute ball that blocks the lower part of the connecting pipe and blocks the water from rising to the sink hose. The sink installed in the basement of the house allows rainwater or rainy season sewage to flow back. The sink can be prevented and the safer sink can be obtained by the quick and accurate reverse flow blocking effect, and the damage of the flood caused by the reverse flow can be prevented, and the disassembly and assembly can be easily cleaned so that the inside of the drain can be easily cleaned. It is about drainage to prevent backflow of sustainable sink.

Generally, the sink is equipped with a drain hose connecting the sink and the drain to drain the water used in the sink to the drain.

However, the drain hose only plays a single role in draining the water used in the sink to the sewer, and does not have a backflow prevention function.

Therefore, in the rainy or rainy season, the sewage backflow is often caused through the sink installed in the basement of the townhouse or the detached house, which causes a lot of damage.

In order to prevent the reverse flow of the sewage has been introduced in the past, a technique for attaching a packing for preventing backflow to the sink stand itself has appeared, the above-described prior art only performs a function only at the usual weak water pressure or only perform a odor removal function strong Water pressure was acting as a backflow sewage could not cope with a certain problem.

The purpose of this article to solve and complement these conventional problems,

The sink installed in the basement of town or detached house can prevent the backflow of sewage during rainy or rainy season, and safer sink can be obtained by the quick and accurate backflow blocking effect, and it can prevent the damage caused by the backflow. It is easy to disassemble and assemble, so that the inside of the sump can be easily cleaned, which serves to maintain the sink in a clean state at all times.

In order to achieve the above object,

Inserting the connecting pipe into the sink hose connected to the sink, and having a lid that is fastened by a fastener, the seating portion formed on the outer periphery of the connector inside the lid body seats a rubber sponge and the outside of the seating portion where the rubber sponge is seated. The upper part is fastened to the lid body so as to contact the packing inserted into the insertion part of the lower part, and the lower part is provided with a drain container connecting the drain hose, and is built into the drain container by the pressure of water flowing back from the drain hose. As it rises and comes in close contact with the inner diameter of the rubber sponge inside the lid, it is possible to achieve the purpose of the present disclosure by providing a flute ball that blocks the lower part of the connecting pipe and prevents water from rising to the sink hose.

The configuration of the present invention will be described in detail with reference to the accompanying drawings.

The lid body 103 which is connected to the sink stand hose 108 connected to the sink stand and is fastened by the fastener 107 by inserting the connector 104.

A rubber sponge 112 seated by a seating portion 105 formed by a connection tube 104 outer periphery of the lid 103;

The upper part is fastened to the lid 103 so as to contact the packing 114 inserted into the insertion part 106 outside the seating part 105 on which the rubber sponge 112 is seated, and the drain hose 109 is provided as the lower part. And the drain container 101 connecting

The inside of the sump (101) is built up by the pressure of the water flowing back from the drain hose 109, close to the inner diameter of the rubber sponge 112 inside the lid 103 to block the lower part of the connecting pipe (104) The flute ball 111 is configured to block water from rising to the sink large hose 108.

Further, in order to reinforce the adhesion of the flute ball 111 in close contact with the rubber sponge 112, the inclined surface 113 formed of the inner peripheral surface of the rubber sponge 112 was further provided.

In addition, a locking rod 102 is further provided inside the drain container 101 to prevent the flute ball 111 of the drain container 101 from falling below a set height.

The operation of this paper is as follows.

First, Figure 1 is a view of the first embodiment showing the configuration of the drainage for preventing the backflow of the present invention, Figure 2 is a functional diagram of Figure 1 for explaining the operation of the drainage for preventing the reverse flow of the present invention, when using a sink in the usual 101, the inner flute ball 111 is in a state of being caught by the catching rod 102 as shown by the solid line or the imaginary line of FIG.

If water is used in a state in which the flute ball 111 is hung on the catching rod 102 as described above, the water of the sink is drained through the connecting tube 104 of the sink hose 108 and the lid 103. It flows into the keg 101.

In addition, the water in the drain container 101 is drained to the sewer through the drain hose 109 coupled to the bottom of the drain container 101.

However, when the sewage in the rain or rainy season sewage flows back, the sewage of the sewer flows into the drain container 101 through the drain hose 109.

As described above, when the sewage of the drain container 101 flows backward, the flute ball 111 in the drain container 101 rises along the sewer surface while floating due to buoyancy, and the air supply field is capped as shown in FIG. 2. The inner diameter of the rubber sponge 112 seated on the inner mounting portion 105 is blocked to be in a state of blocking.

Therefore, since the sewage in the sump 101 is no longer raised and stops, the sewage of the sump 101 flows back to the sink along the sink hose 102 through the connecting pipe 104. You can stop it perfectly.

In addition, when the sewage of the drain container 101 is drained, the flute ball 111 also returns to its original position as shown in FIG. 1 to prepare for the next reverse flow.

On the other hand, if you use the sink, you will not only go down the drain, but also mix down the food.

Therefore, when used for a long time, food waste and the like remain in the drain container 101 of the present article.

At this time, since the lid body 103 in the present invention can be rotated and separated from the drain container 101, the inside of the drain container 101 can be cleaned, so that the sink stand in a clean state can be maintained.

After the cleaning of the drain container 101 is completed, when the lid body 103 is coupled to the drain container 101 again, the packing 114 inserted into the insertion part 106 inside the lid body 103 is provided. Since the tip of the drain container 101 is brought into close contact with each other, airtightness can be maintained.

On the other hand, Figure 3 is a view of the second embodiment showing the constitution of the drain backflow prevention block of the present design, Figure 4 is a functional diagram of Figure 3 for explaining the operation of the drainage for preventing backflow of the present design, in this embodiment a rubber sponge 112 Since the inclined surface 113 is formed on the inner circumferential surface, the adhesion force of the flute ball 111 in close contact with the rubber sponge 112 can be further strengthened, so that a more rapid and accurate countercurrent blocking effect can be obtained.

In this way, this sink prevents the backflow of sewage during rainy or rainy season through sinks installed in the basement of townhouses or single-family houses, and obtains safer sinks by quick and accurate backflow blocking effect. Damage can be prevented and easy to disassemble and assemble so that the inside of the drain can be easily cleaned, which has a useful effect of keeping the sink in a clean state at all times.
