Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. Prior to this, terms or words used in the specification and claims should not be construed as having a conventional or dictionary meaning, and the inventors should properly explain the concept of terms in order to best explain their own invention. Based on the principle that can be defined, it should be interpreted as meaning and concept corresponding to the technical idea of the present invention.

Therefore, the embodiments described in the specification and the drawings shown in the drawings are only the most preferred embodiments of the present invention and do not represent all of the technical idea of the present invention, various equivalents that may be substituted for them at the time of the present application It should be understood that there may be water and variations.

Figure 2 is an exploded perspective view showing the drain trap for the sink of the present invention, Figure 3 is a combined cross-sectional view showing the drain trap for the sink of the present invention, Figure 4 is a AA cross-sectional view of Figure 3, Figure 5 is a socket of the present invention Figure 6 is a cross-sectional view showing a trap, Figure 6 is another embodiment showing the socket trap of the present invention, Figure 7 is a use embodiment showing the sink trap for the present invention.

As shown in FIGS. 2 to 3 and 4, the step portion 11-1 is formed at the lower end of the drain pipe connection portion 11 connected to the drain pipe of the sink, but the center of the step portion 11-1 is shown. An inlet 11-2 connected to the drain pipe connection part 11 is formed at a lower end of the upper body 13 and the upper body 13 in which a fastening screw part 12 is mounted and fastened to the stepped part 11-1. The screw part 14 is formed at the upper end to be fastened to the fastening screw part 12 of the case), and a guide protrusion 15 is formed at one side of the inner side, and a lower case 18 including the sewer pipe connecting part 16 is formed at the lower end thereof. A guide groove 22 is formed at one side to be fitted into the guide protrusion 15 of the lower body 18 of the case 10 and the inlet 11-2 of the drain pipe connection part 11 at the upper surface thereof. ) Is opened to be inserted and is formed by installing a "c" shaped socket trap 20 is formed with a predetermined inclined surface Structure.

The inlet 11-2 is connected to the drain pipe connection part 11 so that the inlet 11-2 is installed in a "t" shaped socket trap coupled to the guide protrusion 15 of the case lower body 18. It should be formed in a length but the bottom bottom surface of the inlet (11-2) should not be in close contact with the inner bottom of the socket trap (20).

That is, the length of the socket trap 20 should be formed so that the water flowing into the socket trap 20 and the water flowing into the socket trap 20 are not easily interfered with the foreign substance and water in the sink.

As shown in FIG. 5, the socket trap 20 has a “c” shape having an open upper side and a guide groove 22 formed at one outer circumferential surface thereof.

As described above, the upper surface of the socket trap 20 may be formed in a straight line, but the water flowing into the socket trap 20 may easily flow out to the lower body 18 of the case 10. It is preferable that the upper surface of the top face) consists of a predetermined inclined surface θ.

That is, the inclined surface θ is an inclined surface θ of which the upper surface of the portion of the guide groove 22 where the socket trap 20 is coupled to the lower body 18 of the case 10 is high and the other upper surface is low. The water flowing into the socket trap 20 prevents water from flowing into the threaded portion 14 to which the lower body 18 of the case 10 and the upper body 13 of the case 10 are coupled. There is an effect that can be induced so that the water can flow out to the sewer pipe connection portion 16 of the lower body 18 of (10).

The shape of the socket trap 20 is preferably formed in a circular or polygonal shape as shown in FIG.

Thus, since the shape of the socket trap 20 varies in shape depending on the amount of water flowing in, the cleaning cycle of the drain trap 1 can be adjusted constantly, and when the drain trap 1 is used in a large amount of sinks, It is effective to make the socket trap large in the place where it is used and to make it small in the place where it is used, and to keep the cleaning cycle constant.

The sink drain trap 1 of the present invention as shown in FIG. 7 is connected to the sewer pipe connection part 16 to the sewer pipe of the bottom in the use embodiment as shown in Figure 7 and fitted into the guide protrusion 15 inside the foreign matter and inflow After installing the lower body 18 is installed the "c" shaped socket trap 20 to contain or discharge the water is connected to the drain pipe connection 11 to the drain pipe and the inlet 11-2 connected to the connection of the drain pipe Is internally installed in the "c" shaped socket trap 20, and then fastened with the lower body 18 by the fastening screw part 12 installed in the stepped portion 11-1 of the connection portion 11 of the drain pipe (1) To complete.

The sink drain trap 1 of the present invention connected as described above has foreign substances accumulated on the inner bottom of the socket trap 20 when the water containing foreign matter is introduced through the drainage port of the sink and the socket trap 20 is water. When overflowed to the sewer pipe connection portion 16 of the lower body 18 and when a large amount of water containing foreign substances flows into the socket trap 20 and the water flowing into the socket trap 20 overflows Outflow to the sewer pipe connection portion 16 of the lower body (18).

When cleaning the socket trap 20, the user is the case of the upper body 13, the lower body 18

The socket trap 20 is separated and separated from the lower body 18 of the case 10 to remove foreign matters accumulated in the inside, and then coupled to the lower body 18 of the case 10.

Thus, the drain trap 1 for the sink of the present invention is easy to replace when broken, it is formed in the "c" shape can be introduced and discharged water without being caught by foreign matter, foreign matter gathered in one place concentrated It has a convenient effect.
