Drain with stench trap < RTI ID = 0.0 >

The present invention relates to a drainage device having a malodor and a backflow shutoff function. In particular, it is installed on a side of a drainage port which is installed on a bathroom and an ovum for drainage of water to efficiently block backflow of odor and water flowing through a drainage port And a drainage device having a malodor and a backflow shutoff function.

A drain hole is provided on the bottom surface of a bathroom or a veranda of each home, hotel or the like so that water can be drained to the outside through the drain hole.

In such a drainage port, various kinds of foreign substances generated during use in a bathroom or a veranda are prevented from being drained through a drainage port, and a drainage device for preventing odor from being introduced into the drainage opening from the outside is installed It is in use.

In the conventional drainage device, a drainage trough is embedded in a concrete layer to separate each layer, and a drainage pipe is connected to a drainage trough embedded from a lower portion of the concrete layer. In the drainage trough, Has a malodor preventing function to prevent odor from flowing through a drain pipe.

The conventional drainage device as described above allows a part of the water drained to remain in the lower end side of the drainage trough such that a part of the lower end of the drainage pipe body is submerged in the remaining water so as to block the odor to be introduced through the drainage pipe .

However, in the conventional drainage device as described above, a part of the end of the drainage pipe body can be submerged in water that is not drained, so that it is possible to cut off the odor to be introduced from the outside through the drainage pipe. However, If the drain pipe is clogged due to clogging or freezing in winter, water that can not be drained may flow back through the draining trough of the upper layer.

Accordingly, the present invention aims at not only allowing the water to be drained smoothly but also effectively blocking odor and water flowing backward from the outside through the drain pipe.

In order to realize such a purpose, the present invention proposes a drainage device in which a drainage pipe body having a flange is embedded in a drainage hole formed in a concrete layer to allow water to be drained after use,

A malodor and a backflow preventing part which is operated by the water pressure at the time of backflow and blocks the drain port to prevent backflow, is formed in the drain pipe body, and the malodor can be blocked by a part of the water drained, ,

A water flow pipe for allowing the water to flow so that the malodor and the backflow prevention portion are spread over the water pipe;

A water residue passage allowing a part of the water to be drained in a state of being positioned below the drain pipe body;

A guide piece extending from the upper peripheral edge of the upper surface of the water retainer so as to freely move the inner peripheral surface of the drain pipe body;

And a locking protrusion protruding outside the upper end of the guide piece to allow the locking protrusion to pass over the upper surface of the drain pipe body.

The guide pipe may further include a guide hole for guiding the guide member up and down in a state where the guide member is positioned on the inner circumference of the water pipe.

The present invention is characterized in that when the water is drained, the water is drained smoothly, and when the drainage is completed, a certain amount of water remains in the water reservoir and the water flow pipe is immersed in the water remaining in the water reservoir. It is possible to make a living in a state in which the unpleasant feeling due to the odor can be completely eliminated because the inflowing odor can not enter into the room. Further, when the drainage pipe is closed and water is drained, So that the bottom surface of the water flow pipe is brought into close contact with the bottom surface of the water retaining pail so that the user can live in a state in which the backwash of water is originally blocked.

Fig. 2 is a cross-sectional view showing the configuration of the present invention,
FIG. 2A is a view showing a state where drainage is performed in a normal state. FIG.
FIG. 2B is a state diagram when backflow of water occurs. FIG.

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

FIG. 1 is a partial cutaway exploded perspective view showing the construction of the present invention, and FIG. 2 is an assembled cross-sectional view showing the construction of the present invention. In the drainage device of the present invention, a drainage hole 11 is installed on one side of a concrete layer 10 A drainage groove portion 20 is embedded in the drainage hole and an odor and a backflow prevention portion 30 are provided in the drainage drainage portion 20 to prevent odor and backflow.

The drainage trough tube portion 20 constitutes a flange 21 which can be placed on a step surface provided on the upper surface of the concrete layer 10 with the drainage hole 11 as a center, And a drain pipe body 22 for allowing the drain pipe to be fitted is formed.

At this time, the upper surface of the flange covers the blocking plate 23-1 having drainage in order to prevent various foreign substances such as hair contained in the drainage water from being drained.

The malodor and backflow prevention part 30 is formed so as to extend over the upper surface of the drain pipe body 22 connected to the flange and form a water flow pipe 31 passing through the drain pipe body 22, 22, a water retaining tube 32 is formed to allow a part of the water drained through the water flow tube to remain. The water retaining tube has a guide piece (not shown) 33 so that the guide piece is brought into contact with the inner circumference of the water pipe body so that the catching jaws 34 can be caught on the upper surface of the water pipe body so that the water retainer pipe is positioned at the lower portion of the water pipe body And the water reservoir can freely be lifted and lowered.

At this time, a part of the lower end portion of the water flow pipe (31) can be positioned at the inner side of the water retaining cylinder (32) so that the water remaining in the water retaining cylinder is always kept in a locked state, Is not introduced.

A guide hole 23 is formed in the inner circumference of the water pipe 22 so that the guide piece 33 can be inserted and moved.

2A, the guide piece 33 of the water retainer 32 passes through the inner circumferential edge of the drain pipe body 22 and is provided at the upper portion of the guide pipe The water retaining tube 32 is located below the water pipe body because the retaining jaw 34 is engaged with the water pipe body 22. At this time, (See FIG. 2).

When the water is drained in this state, the water passing through the drain hole of the blocking plate 23-1 is drained through the water flow pipe 31 provided in the drain pipe body 22, The water that has passed through the water retaining cylinder 32 is drained through the drain pipe as the water is continuously drained from the water retaining cylinder 32 in this state.

When the drainage of water is completed in the above-described state, water remains in the water retaining cylinder 32, and a part of the lower end of the water flow pipe 31 is locked in the remaining water.

In this state, the odor generated from the lower layer flows into the upper layer through the water pipe. At this time, since a part of the lower end of the water flow pipe 31 is in the state of being submerged in the water remaining in the water retaining cylinder 32, The odor can not pass through the water flow pipe 31, thereby completely stopping the inflow of the odor.

In addition, a phenomenon occurs in which the water pipe is clogged by various foreign substances drained in the state where the water is drained. In such a case, the water flowing into the drain pipe may not be drained and may be refluxed.

When the water is not drained as described above and the water flows backward through the water pipe, the water retaining cylinder 32 floats up due to the water pressure of the water flowing backward as shown in FIG. 2B, and the water retaining cylinder 32 The lower end surface of the water flow pipe 31 is brought into close contact with the bottom surface, so that the water flowing back through the water flow pipe 31 is blocked by the water retaining tube 32 and water can not flow back into the room.

Then, when the drainage pipe is closed and water is drained, the water retaining cylinder 32, which has been lifted by the water pressure of the water flowing backward, descends downward as shown in FIG.
