Sinks or wash basins that are widely used in homes are provided with drains, which are connected to drain pipes, and drain pipes are connected to drains. Generally, a drain trap is provided in the drain pipe as a malodor blocking means for blocking the odor coming from the sewer.

Among the drain traps which have been widely used in the prior art, there are those which are bent into an "S" shape. This type of draining trap is difficult to manufacture and has a problem that the unit price rises and cleaning is difficult.

Recently, a drainage trap has been proposed, which is assembled with a product that can be disassembled and assembled. The drain trap includes an upper cap, a lower cap screwed into the upper cap, and a trap member fitted in the upper cap and the lower cap. That is, the conventional drain trap is composed of three or more parts and complicated (refer to Korean Patent Application No. 10-2018-0044510) and the installation direction is limited because the drainage is made in the downward direction.

Also, the drain trap of Korean Utility Model Registration Application No. 20-2014-0005820 having an integral structure has a problem that the construction is complicated.

And a lower low water hole (S2) having an upper side opened to form a part of the water storage space (S) is formed inside the second water hole (5a), and a lower low water hole And a second cup (5) formed with a tubular second extension pipe (13) having a predetermined height on the bottom surface of the stem (S2). The second cup (5)
When the first cup 3 and the second cup 5 are coupled to each other, the upper and lower low-flow passages S1 and S2 are correspondingly closed to each other, and the first and second extension pipes 11 and 13 Are formed so as to intersect with each other in a predetermined interval in the water storage space S, and the shapes of the first cup 3 and the second cup 5 are the same as each other in a planar shape, a polygonal shape and an elliptical shape Respectively.
The odor prevention drainage trap (1) according to the present invention is installed at the bottom of a sink or basin (100) widely used in the home. The water drained through the drain hole (101) of the washstand is discharged to the drain hole (201) provided in the building floor (200) through the drain trap (1). An upper pipe 103 is connected between the drainage trap 1 and the washstand 100 and a lower pipe 105 is connected between the drainage trap 1 and the drainage hole 201. The upper pipe 103 and the lower pipe 105 may have different shapes. According to the drawings, the upper pipe 103 is a corrugated pipe.

The malodor-preventing drainage trap 1 according to the present invention basically comprises a first cup 3 and a second cup 5 which are in the form of two parts, namely a cylindrical shape. And the remaining components can be attached to the first and second cups 3 and 5 integrally so that they can be regarded as being composed of two parts as a whole. The first cup (3) and the second cup (5) are coupled to each other to provide a water storage space capable of maintaining watertightness. The first and second cups 3 and 5 may be either planar polygonal or elliptic.

The first cup (3) and the second cup (5) are joined to each other to create a sealed water storage space. One or both of the first cup 3 and the second cup 5 may be made of a transparent material so that the inside can be seen.

An L-shaped guide groove 15 is formed on an outer surface of the first cup 3 and an engaging projection 17 is formed on an outer surface of the second cup 5 to be fitted into the guide groove 15 Can be protruded. The guide groove 15 and the engaging projection 17 may be provided at two positions along the circumferential direction of the first and second cups 3 and 5.

The first extension pipe 11 is installed in the first through hole 3a of the first cup 3 and extends into the water storage space S. The second extension pipe 13 is connected to the second through hole 5a of the second cup 5 and extends into the water storage space S. The first and second extension pipes 11 and 13 are installed so that their end portions do not collide with each other. The sum of the lengths of the first and second extension pipes 11 and 13 is larger than the height of the water storage space S so that the first and second extension pipes 11 and 13 overlap within the water storage space.

According to the embodiment of the present invention, the first and second through holes 3a and 5a may be eccentrically installed in the first and second cups 3 and 5, respectively. The diameters of the first and second through holes 3a and 5a and the inner diameters of the first and second extension pipes 11 and 13 may be the same as shown in FIG. The first and second cups 3 and 5 may be provided in the same shape and size. The first and second extension pipes 11 and 13 may be installed so that their outer walls contact each other as shown in FIG.

A first connection pipe 7 for connecting the upper pipe 103 connected to the sink or sink 100 is provided in the first through hole 3a of the first cup 3, And a second connection pipe 9 for connection with the lower pipe 105 is provided in the second through hole 5a.

According to the embodiment of the present invention, the first connection pipe 7 is integrally formed with the first extension pipe 11, and the second connection pipe 9 is integrally formed with the second extension pipe 13 Can be. All of these can be made up of a single product. Therefore, the drainage trap 1 of the present invention can be composed of a total of two parts.

The first and second extension pipes 11 and 13 and the first and second connection pipes 7 and 9 may be installed in the first and second cups 3 and 5 in a prefabricated manner.

4, when the drain trap is installed in the vertical direction, the drain water is in the direction of the arrow K, and the water introduced into the first through hole 3a flows into the second extension pipe 13 to the upper end 13a. And the lower end 11a of the first extension pipe 11 will be located below the water surface of the pooled water. The water surface height H of the water will correspond to the length of the second extension pipe 13. By adjusting the length of the first and second extension pipes 11 and 13, the height H of the water surface and the depth of the first extension pipe 11 can be adjusted.

According to the above-described structure, the odor coming through the sewage hole 201 stays in the space above the water surface and can not flow upward along the first extension pipe 11.

FIG. 6 shows another embodiment of the present invention in which the diameters of the first and second extension pipes 11 and 13 may be different from each other. As such, the first and second extension pipes 11 and 13 may have different sectional shapes or different diameters.

Fig. 7 shows a state in which the drain trap 1 according to the present invention is installed in the lateral direction.

The first cup 3 and the second cup 5 are arranged vertically so that the water to be drained reaches the height of the lower end of the second extension pipe. And the odor stays in the water storage space S formed by the first and second cups 3 and 5 and can not flow back through the first extension pipe 3.

According to the embodiment, a description or an indication as to which should be placed on the upper side can be engraved on the outer surface of the first and second cups.

As such, the drain trap of the present invention can be installed vertically or horizontally as shown in FIGS. That is, there is no restriction on the installation direction, so that it can be used for general purpose. Further, since the flow path is simple and wide like a conventional drain trap, drainage can be smoothly performed.

The drainage trap 1 of the present invention can be provided to the consumer in the form as shown in Fig. And a JAVA LASIK lower pipe 105 directly connected to the sewer may be provided in a combined state.
