The multi-coupling assembly A for a sink drain hose according to the present invention comprises a coupling 10 connected to a drain hose S1 of a sink S as shown in Figs. 1 to 3, And a connection pipe 20 connecting the water pipe 10 and a sewage pipe S2 provided in a building or the like.

More specifically, the coupling 10 includes a main body 11 having a cylindrical shape such as a general sewage pipe S2, and a plurality of drain holes 12 And a cover 15 for opening and closing the drain hole 12. At this time, the drain hole 12 may be formed of various numbers, and the scope of the right should not be limited. The drain hole 12 is formed of a fastening part 121 protruding from the outer surface of the main body 11. A fastening thread 121A is formed on the outer surface of the fastening part 121. [ The main body 11 is provided with a cover 15 which is coupled to the coupling part 121 so as to cover the drain hole 12. An inner side of the cover 15 is provided with a fastening screw A corresponding thread 153 that engages with the threaded portion 121A is formed. Therefore, when the drain hose S1 is connected to the coupling 10, the unused drain hole 12 is screwed into the fastening thread 121A and the corresponding thread 153, (121), it is possible to prevent the fluid flowing through the drain hose (S1) from leaking out.

2 and 3, when the drain hose S1 such as a sink S or a water purifier is coupled to the drain hole 12, the drain hose S1 is inserted into the cover 15, A hollow 155 is formed. The drain hose S1 is inserted into the hollow 155 of the cover 15 and inserted into the drain hole 12 and then the cover 15 is screwed to the coupling part 121 to form the drain hose S1 ) To the coupling (10). A fluid flowing through the drain hose S1 may leak into a gap between the drain hose S1 and the drain hole 12 due to a difference in size between the diameter of the drain hose S1 and the diameter of the drain hole 12, The present invention is further provided with a leak-proof packing 17 that is coupled to the drain hole 12 of the coupling 10.

2 and 3, the leak-proof packing 17 is coupled between the drain hole 12 and the cover 15, and has a diameter decreasing in the entering direction of the drain hole 12 And has a truncated cone shape. More specifically, the leak-preventive packing 17 is made of rubber, silicon or the like and has a through hole 171 through which the drain hose S1 can pass, And the diameter of the truncated cone is gradually decreased in the entering direction of the drain hole 12 from the contact surface in contact with the inner surface of the drain hole 12.

Therefore, when the drain hose S1 is coupled to the drain hole 12, the drain hose S1 is passed through the hollow 155 of the cover 15, and when the diameter of the truncated cone is large (for convenience, The drain hose S1 is inserted into the drain hole 12 after passing through the drain hole 171 in a direction of a small diameter (for convenience sake, the upper surface).

At this time, when the cover 15 is screwed to the coupling part 121, the lower surface of the leakage preventing packing 17 presses the inner surface of the cover 15 toward the drain hole 12, The leakage preventing packing 17 is sandwiched between the drain hose S1 and the fastening part 121 and the slope part 173 formed on the outer surface of the leakproof packing 17 can prevent the cover 15 The gap between the drain hose S1 and the drain hole 12 can be completely blocked as the pressure is applied toward the drain hole 12 gradually between the drain hole 12 and the drain hose S1, Or the fluid can be prevented from flowing backward. When the diameter of the drain hose S1 matches that of the drain hole 12 and is connected to the drain hole 12 provided at the upper portion of the coupling 10, It is preferable that the diameter of the through hole 171 provided in the leakproof packing 17 is increased so as to be inserted together to prevent backflow of fluid and odor.

Further, the multi-coupling assembly for a drain hose according to the present invention can completely prevent a leakage of water from a space between the bottom S3 of the sink and the bottom by completely connecting a plurality of drain hoses to one drain pipe The leakage can be visually confirmed easily by the naked eye and it is possible to prevent flooding caused by not recognizing the leak.

1 to 3, the multi-coupling assembly A for a sink drain hose according to the present invention includes a coupling portion 21 to be screwed with the main body 11 of the coupling 10 A connecting pipe 20 is provided.

More specifically, a coupling portion 21 is formed on the inside of the upper portion of the connection pipe 20 to form a coupling thread 211, and a coupling portion 21 is formed on the lower portion of the coupling pipe 20 so as to be coupled to the coupling portion 21 A corresponding engaging portion 112 is formed on the outer side so that the engaging threads 211 and corresponding engaging threads 112A are formed. Therefore, the connection pipe 20 is connected to a sewage pipe S2 installed on a building or the like by a joining means 30 to be described later, and the upper portion of the connection pipe 20 is protruded from the bottom surface S3 of the sink And is coupled with the coupling 10 through the threaded engagement of the coupling portion 21 of the coupling pipe 20 and the corresponding coupling portion 112 of the coupling 10.

Generally, the drain hose S1 of the sink S is formed in a zigzag shape. When food or various foreign substances enter the drain hose S1, a flexible tool is removed to remove the food or various foreign substances. However, this method is difficult to confirm the position of the foreign object and is difficult to remove if the sewage pipe S2 is clogged by foreign matter. In addition, the drainage pipe and the drainage hose are connected to the space between the bottom surface S3 and the kitchen floor. In order to remove the foreign substances from the drainage pipe S2, ), Or to separate the sink, which is costly and cumbersome. Therefore, in order to solve this problem, the present invention has a connection pipe 20 connected to a drainage pipe S2 to be coupled to the coupling 10, and an upper part of the connection pipe 20 is connected to a bottom surface S3 to a certain distance upward. Therefore, when the foreign object is removed, the coupling 10 is removed from the connecting pipe 20, and the connecting pipe 20 is protruded upward so that the bottom surface S3 of the sink of the sewage pipe S2 The foreign matter trapped in the sewage pipe S2 can be removed without detaching a part of the sewage pipe S2, thereby reducing the maintenance cost.

Further, since the connection pipe 20 protrudes above the bottom S3 of the sink, the sink bottom drainage pipe portion and the rear hose position become vertical structure, so that there is no need to move the sink during repair, It is easy to repair.

When the coupling portion 21 of the coupling pipe 20 and the corresponding coupling portion 112 of the coupling 10 are screwed together in coupling the coupling pipe 20 and the coupling 10, And a fluid or odor may leak out through the gap. In order to solve this problem, a first flange 111 is provided on the outer surface of the main body 11 and a corresponding flange 111 is provided on the corresponding coupling part 112. On the upper part of the second connection pipe 20, The second flange 23 is provided at a position corresponding to the first flange 111 and the waterproof packing 25 is formed between the first flange 111 and the second flange 23 in a ring shape. More specifically, the waterproof packing 25 has the same shape as the first and second flanges 23, has a ring shape so that the fluid can be moved to the sewage pipe S2, is generally elastic , Rubber material with high water-proof function, silicone material, etc. Therefore, when the coupling 10 and the connecting pipe 20 are coupled by the threaded engagement of the corresponding engaging portion 112 and the engaging portion 21, the first flange 111 and the second flange 23 are engaged with the waterproof The packing 25 is pressurized and brought into close contact with it, so that fluid or odor can be prevented from leaking to the outside.

The coupling unit A for the drain hose according to the present invention is further provided with a coupling unit 30. More specifically, the coupling unit 30 connects the coupling pipe 20 and the sewage pipe S2 And is located at the bottom of the bottom of the sink S where the sewage pipe S2 is provided. More specifically, when the sewage pipe S2 and the connection pipe 20 are coupled to each other, the joining unit 30 prevents the gap from being shifted from each other, So that the sewage pipe S2 can be inserted into the lower portion of the joint means 30. [ The inner diameter of the coupling means 30 is larger than the outer diameter of the coupling pipe 20 so that the coupling pipe 20 can be inserted into the upper portion of the coupling means 30. At this time, the annular protrusion 31 is provided on the inner side surface of the joint means 30 and the upper surface of the sewage pipe S2 is closely fixed to the lower surface of the protrusion 31, And the lower part of the connection pipe 20 is tightly fixed to the upper surface. Therefore, even if the diameters of the sewage pipe S2 and the connection pipe 20 are slightly different from each other, the error can be overcome and the connection between the joining means 30 and the sewage pipe S2, The piping 20 may be tightly coupled to the piping 20, or may be coupled using a separate adhesive, and the scope of the right should not be limited.

Furthermore, in general, the diameter of the drain hose S1 for the water purifier is very small. Therefore, when the drain hose S1 is configured to be smaller than the diameter of the drain hole 12, it is difficult to be fixedly coupled to the drain hole 12. Therefore, in order to solve this problem, the present invention has a configuration in which the cover 15 is provided with the thin portion 151 and the display portion 151A is provided on the outer surface of the cover 15 at a position corresponding to the thin portion 151 The position of the thin portion 151 is displayed. More specifically, as shown in FIG. 3, the thin portion 151 is provided on the cover 15, but is configured to be thinner than the thickness of the cover 15. When the display unit 151A is provided on the outer surface of the cover 15 in correspondence with the position of the thin portion 151 to connect the drain hose S1 having a small diameter such as the water purifier drain hose S1, The drain hose S1 is connected to the drain hole 12 by cutting the thin portion 151 and pushing the drain hose S1 in a state where the drain hose S1 is connected to the coupling portion 121 And the positions and the number of the thin portions 151 may be variously configured and the sizes thereof may be variously configured.

As a result, the multi-coupling assembly A for a sink drain hose according to the present invention is provided at a lower portion of the sink S as shown in FIG. 4, and the drain hose S1 of the sink S, And the drainage hose S1 such as the drainage hose S1 can be connected at the same time. When a plurality of drainage hoses S1 are installed in the one drainage pipe S2, the drainage hose S1 is prevented from leaking, .

Further, although not shown in the drawing, it is also possible to provide only one drain hole provided in the coupling above the main body for the sink, and the scope of the right should not be limited.

In the above description, the multi-coupling assembly for a drain hose of a sink having a specific shape, structure and configuration has been described with reference to the accompanying drawings.
