2 is an assembled cross-sectional view showing the structure of the present invention,
FIG. 2A is a state in which the water retaining cylinder is free of water. FIG.
2B is a state in which water is drained in the water retaining cylinder.

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

FIG. 1 is a partially cutaway exploded perspective view showing a construction of the present invention, and FIG. 2 is an assembled cross-sectional view showing the construction of the present invention. In the drainage apparatus of the present invention, a drainage hole 11 is installed on one side of a concrete layer 10 do.

The drain hole (20) is embedded in the drain hole (11).

The drainage trough tube 20 constitutes a flange 21 which can be placed on a stepped surface provided on the upper surface of the concrete layer 10 with the drainage hole 11 as a center and the drainage hole 11 And a drain pipe body 22 for inserting the drain pipe 12 embedded in the drain pipe 11 is formed.

At this time, a stepped surface () having a guide hole () for allowing a guide rod provided in a water retaining tube to be described later to pass therethrough is formed on the inner peripheral surface of the lower end portion of the water pipe body 22, A cover plate 24 having a drain hole 24a is covered to prevent various foreign substances such as hair contained in water from being drained.

In addition, the drainage groove portion 20 is provided with a malodor and a backflow prevention portion 30 for preventing odor and backflow.

The malodor and backflow prevention part 30 is formed on the upper surface of the water pipe 22 connected to the flange to form a water flow pipe 31 passing through the water pipe 22, A water retaining cylinder 32 is formed in the lower portion of the water retaining cylinder 22 so that a part of the water drained through the water flow pipe can remain. The water retaining cylinder has a guide hole 23a So that the water retaining cylinder can be moved up and down according to the rise and fall of the guide rod.

The upper end of the stop ring 23 is positioned on the upper end of the guide rod 33. The lower end of the stop ring 23 is positioned on the upper surface of the step 23, 34).

At this time, a locking groove 33a is formed at the outer periphery of the upper end of the upper end of the guide rod 33 so that the locking ring 34 can be engaged with the locking ring 33. The locking grooves are arranged at a certain interval, It is possible to adjust the position of the stop ring according to the elastic pressure of the elastic part or the gap between the water flow pipe and the water residual passage depending on the length of the water flow pipe.

In addition, the elastic part 35 is pulled up to the upper side by the elastic force of the elastic part 35 so that the lower end surface of the water flow pipe 31 can be kept in a grounded state at the bottom surface of the water retaining cylinder 32 When elasticity of the elastic part is such that water remains in the water retaining barrel, the elastic force of the elastic barrel is compressed by the weight of the elastic bar, so that the elastic bar has a resilient force enough to lower the water retaining barrel.

 2A, the guide rod 33 of the water retaining cylinder 32 is guided from the lower portion of the stepped surface 23 provided inside the lower end portion of the water pipe body 22, The elastic portion 35 is covered with the guide rod 33 exposed to the upper portion of the stepped surface in a state of passing through the guide groove 23a and then the stop ring 34 is inserted into the engagement groove 33a provided in the upper end portion of the guide rod The resilient portion 35 which is pushed to penetrate the guide rod 33 is mounted on the upper surface of the stop ring 34 and the step 23 so that the guide rod is pulled up to the upper portion by the elastic force of itself. The lower end surface of the water flow pipe 31 is maintained in a grounded state on the bottom surface of the water retainer 32. [

When the water is drained in this state, the water flows into the water flow pipe 31 passing through the drain hole 24a of the shutoff plate 24 and running in the drain hole trough 20, 32 are raised by the elastic force of the elastic portion 35 to bring the bottom surface into close contact with the water flow pipe and drainage is not carried out. Then, due to the weight of the continuously flowing water, The lower end surface of the water flow pipe 31 and the bottom surface of the water retaining tube 32 are separated from each other as the lower surface of the water flow pipe 31 is downward while compressing the elastic portion 35. Accordingly, And the drainage is made through the drain pipe (11) by flowing over the cylinder (32).

When the waste water is drained by the above-mentioned state, the drainage water remaining in the water retaining cylinder 32 remains. At this time, the elastic part 35 compressed by the weight of the water remaining in the water retaining cylinder becomes the original state The portion of the lower end of the water flow pipe 31 remains in a state of being settled in the residual water remaining in the water retaining cylinder 32. [

Because of this relationship, the odor that flows back through the drain pipe (12) can not come into the room through the water flow pipe (31) settled in the residual water remaining in the water residual bottle (32) .

When the water that has been drained through the drain hole 12 flows backward, water flowing backward strikes against the bottom surface of the water retaining cylinder 32, and by the pressure of water flowing backward against the bottom surface of the water retaining cylinder as described above The water retaining cylinder 32 containing the residual water rises and is brought into close contact with the bottom surface of the water flow pipe 31 on the bottom surface so that the water flowing backward can not flow back through the water flow pipe.

When the water does not flow backward, the water retaining cylinder 32 compresses the elastic part 35 by the weight of the residual water remaining in the water retaining cylinder 32 to maintain the downward state.

Even in this case, a part of the lower end portion of the water flow pipe 31 is kept in the water remaining in the water retaining cylinder 32, thereby blocking the inflow of the offensive odor.

When the water is not drained for a predetermined period of time in the above-mentioned state, the moisture in the room is evaporated due to the temperature of the room or surrounding environment. In this case, the remaining water in the water retaining cylinder 32 also evaporates The water level is lowered.

When the water level becomes lower as described above, the water retaining cylinder 32 rises due to the returning force of the elastic part 35 which is compressed in proportion to the weight of the lost water, so that the lower end part of the water flow pipe 31 32 are continuously maintained in the state of being precipitated in the water that has been drenched in the water.

When the water remaining in the water retaining cylinder 32 is finally lost due to no drainage in the above-described state, a water flow is generated on the bottom surface of the water retaining cylinder 32 as shown in FIG. 2A And is adhered to the lower end surface of the pipe (31), so that the inflow of odor can be blocked even in the absence of water in the water remaining cask.
