1 to 5, the drain trap 100 has a body frame 110, a drain residual container 140, and a drain induction container 170.

The main body frame 110 is installed to be embedded in the bottom of the bathroom in which the drain pipe (see FIG. 5; 210) is formed and is connected to the drain pipe 210.

The body frame 110 is formed of a frame forming portion 112 formed in a rectangular shape, and a coupling pipe portion 120 formed in a tube shape.

The frame forming part 112 is formed with a seating groove 114 for forming a catchment space by mounting the filter cover 180 having a plurality of drainage holes 182 formed therein.

The coupling pipe part 120 extends downward to be inserted into the drain pipe 210 at the center of the frame forming part 112 and has a structure having a hollow 122.

The ring-shaped seating jaw 125 is formed to protrude toward the center portion along the inner circumferential surface on the lower inner side of the coupling pipe part 120, and is inserted into the lower portion so as to accommodate a portion of the water drained on the upper surface. The bone 127 is formed.

In addition, on the coupling pipe portion 120 of the main body frame 110, the locking jaw 174 formed to protrude in the direction in which the outer diameter extends to the drainage induction pipe 170 and the second flange 172, which will be described later, is used for lifting and reverse rotation. As can be easily identified through Figure 6 to be detached by the engaging grooves 126 formed in the 'b' shape is formed in each 180 degrees position.

The drainage remaining container 140 is mounted on the ring-shaped seating jaw 125 so as to receive fresh water for sealing, and is composed of a first flange 142 and a reservoir body portion 146.

The reservoir body portion 146 is formed in the shape of a circular cup capable of fresh water, but has a structure in which a plurality of drainage windows 147 are formed on the side thereof.

That is, the reservoir body portion 146 is formed in a cylindrical shape to enter a predetermined depth into the drain pipe 210, the lower portion is closed to a certain height from the bottom surface 146a so that water can be received, the circumference on the side Four drain windows 147 opened in a rectangular shape spaced apart from each other along the direction are formed at the same height.

The first flange 142 extends in the direction in which the outer diameter extends from the upper portion of the reservoir body portion 146 to be seated on the ring-shaped seating jaw 125. An extended ring odor blocking protrusion 144 is formed.

Here, the width and length of the ring-shaped odor blocking protrusion 144 is a water reservoir so that the odor flowing back through the inner circumferential surface of the coupling pipe portion 120 can be watertightly filled by the water and the odor blocking protrusion 144. 127 is formed shorter than the width and depth.

The drain induction container 170 is seated on the drain residual container 140 to guide most of the drainage and serves to shield the drainage window 147 together with the water remaining in the drain residual container 140.

The drain guide cylinder 170 extends from the second flange 172 seated on the upper surface of the first flange 142 to the cylindrical water storage body portion 146 of the drain residual cylinder 140 with the inner diameter gradually narrowing. It is formed.

Here, the end of the drain guide tube 170 is formed to have an extended length than the bottom of the drain window 147 in the assembled state.

In addition, as described above in the second flange 172 of the drain guide tube 170, two locking projections 174 protruding in a square shape are formed at 180 degrees.

The supporting protrusions 177 are formed to protrude spaced apart from each other along the circumferential direction at intervals of 90 upwards so as to support the capping cover 180 on the upper surface of the drain guide tube 170.

Reference numeral 187 denotes a ring-shaped packing member installed for packing between the first flange 142 of the drain residual container 140 and the second flange 172 of the drain guide tube 170. The ring packing member 187 may be omitted.

On the other hand, in the state in which the drain induction container 170 and the drainage residual container 140 are locked to the body frame 110, the water flowing through the locking groove 126 to increase the drainage amount to the reservoir 127 is ring-shaped. The portion extending from the inner circumferential surface of the coupling pipe portion 120 at a position corresponding to the vertical portion in the 'b' structure of the locking groove 126 to be easily guided to the reservoir bone 127 of the seating jaw 125 A portion of the ring-shaped seating jaw 125 may be formed to cut down to the bottom depth of the reservoir 127 to form a flow guide groove 128 formed to be recessed downward.

In addition, the peripheral portion of the bottom surface of the first flange 142 is opposed to the ring-shaped mounting jaw 125 of the bottom surface of the first flange 142 to reduce the contact area of the portion in close contact with the ring-shaped mounting jaw 125 of the drain residual container 140 and increase the amount of drainage. Of course, the support protrusions 143 may be formed to be spaced apart from each other along the direction to form a structure seated on the ring-shaped seating jaw 125. In this case, the spaced spaces between the support protrusions 143 may further increase the water circulation path.

In the drain trap 100 described above, most of the water in the draining process is dropped through the inside of the drain induction container 170 to be collected into the drain residual container 140, and the overflowed water is discharged through the drain window 147. Drained into the drain pipe 210, the water flowing through the some locking groove 126 and introduced through the reservoir bone 127 is the outer peripheral surface of the drainage residual container 140 and the inner surface of the ring-shaped seating jaw 125 when overflowed Discharged between.

The drain trap 100 is blocked by the water remaining in the reservoir, the odor flowing back between the outer circumferential surface of the drainage residual container 140 and the inner surface of the ring-shaped seating jaw 125 is blocked, the smell flowing back to the drainage window 147 Odor is blocked by the water remaining in the drainage reservoir 140.
