Description

Drain unit for sink

The present invention relates to a sink drain unit installed in the bucket portion of the sink, more specifically, the fastening of the catch ring and the sump of the bucket upper and lower sides is easy and can be easily matched to the overflow hose of the side And a drainage unit for the sink.

In general, a sink is used for cooking or washing dishes in a kitchen, and includes a cabinet part that forms a storage space therein, a top plate that is mounted on an upper part of the cabinet part to form a countertop, and a plate that is mounted on one side of the top plate to wash dishes and fruits. It is composed of a bucket portion provided with a space for washing or vegetables, and a drainage unit installed in the bucket portion for discharging water washed dishes or food, etc. to the outside.

Since the drainage unit of the sink is a part of discharging water, if the connection is poor or old, some of the drained water may leak.If water containing food waste is leaked, the surroundings of the drainage unit may be contaminated. This will cause problems such as odors. In particular, leakage occurs mainly at the coupling site where the bucket part and the drainage unit are coupled. Thus, conventionally, a drainage unit for preventing water leakage by providing a rubber packing at a portion in contact with the bucket part has been developed and widely used.

As shown in FIG. 1, the sink drain unit according to the related art may be separated into the drain container 30 attached to the bottom surface of the bucket 10 and the drain container 30 from above the bucket 10. Filter net 12 is built in, the lid 11 to cover the open upper surface of the drain box 30, the engaging ring 20 is attached to the upper surface of the bucket 10 to support the filter net 12 and , Odor prevention cap 13 embedded in the drain box 30, the overflow hose 60 connecting the side and the drain box 30 of the bucket 10, and the drain connected to the bottom of the drain box (30) It consists of a hose (50).

The bucket 10 and the drainage unit constituting the sink as described above are supplied in a state in which the sink 10 is integrally assembled and modularized for the convenience of installing the sink. The process of assembling the bucket 10 and the drainage unit first includes a locking ring 20 ) Is mounted on the bucket 10 so that the locking ring 20 protrudes below the bucket 10 through the through hole of the bucket 10, and then the water container 30 and the locking ring ( 20 is fastened and proceeds in order to connect the drain hose 50 and the overflow hose 60 to the drain hole 32 formed at the lower side of the drain container 30 and the opening 33 formed at the side, respectively. do.

At this time, the packing 40 is interposed between the locking ring 20 and the upper surface of the bucket 10 and between the drain container 30 and the lower surface of the bucket 10 to prevent leakage. Here, the packing 40 is made of a ring-shaped and elastically deformable material having a rectangular cross section, is pressed by the engaging ring 20 and the sump 30 to maintain the airtightness.

However, in the case of the drainage unit according to the related art, the fastening of the catch ring 20 and the drain container 30, the fastening of the drain container 30 and the drain hose 50, the drain container 30 and the overflow hose 60 In fastening of the screw is configured to be fastened in a coupled manner. In this case, since it is fastened at both sides around the sink bucket, the work becomes difficult, and in the case of the installed sink, the fastening work is difficult because the work is performed in a narrow ball under the sink.

In addition, when the overflow container 60 and the overflow hose 60 are fastened, the direction of the opening 33 formed on the side of the drain container 30 must coincide with the overflow hose 60 so as to distort the overflow hose 60. This does not occur. In the related art, in order to match the position of the opening 33, the opening opening 33 must be aligned with the eye mass in the process of combining the drain box 30 and the locking ring 20, thereby not being accurate.

In addition, a fixing groove 72 is formed at the end of the coupling groove 71 so that the coupling protrusion 34 of the drain hole 32 can be fixed. The fixing groove 72 prevents the coupling protrusion 34 from being released backward along the coupling groove 71 in a state where the coupling protrusion 34 is completely fitted along the coupling groove 71.

In addition, although the coupling groove 71 may be formed by cutting as shown, the inner wall of the cylinder may be formed as a recessed groove, and the coupling protrusion 34 and the coupling groove 71 are each formed in pairs, respectively. It is preferable to be.

On the other hand, the inside of the fastening unit 70 is formed with an insertion groove 73 for inserting the end of the drain hole 32, as shown in Figure 7 the insertion groove 73 is the end of the drain hole 32 When the fastening unit 70 is inserted into the fastening unit 70, the drain hole 32 and the fastening unit 70 maintain the airtight state to prevent leakage, and the end of the drain hole 32 is connected to the fastening unit 70. It is to be inserted while being in close contact with both walls of the insertion groove (73).

As shown, the insertion groove 73 is formed such that the inner wall surface of the fastening unit 70 forms an inclined surface inward, and the guide rim 74 is protruded again on the inner side of the inclined surface, and the guide rim 74 is formed. Is inclined inwardly so as to narrow in width along the fastening direction. By the above structure, as the end of the drain port 32 is inserted into the insertion groove 73, the airtightness between the drain port 32 and the fastening unit 70 is further improved.

The other side of the fastening unit 70 is inserted into the drain hose 50. The water drainage is provided along the outer edge of the other side while securing a space 75 for fitting the end of the drain hose 50 between the outer wall. A crimping rim 76 is formed for crimping the end of the hose 50. The end of the drain hose 50 is forcibly inserted into the space 75, and is pressed by the crimping rim 76 to ensure airtightness between the fastening unit 70 and the drain hose 50. In this case, an adhesive or the like may be used for the outer wall of the fastening unit 70 and the inner wall of the drain hose 50.
