Description

Drain unit of sink

The present invention relates to a sink component, and more particularly to a drain unit that can increase the efficiency according to the sink manufacturing.

In general, the sink is used for cooking, washing dishes, and the like in the kitchen, and as shown in FIG. 1, a cabinet part 10 that forms a storage space therein and an upper part of the cabinet part 10 are mounted on a kitchen counter. It comprises a top plate 20, a bucket (30) mounted on one side of the top plate 20, and a drainage unit attached to the bucket (30).

The drainage unit serves to smoothly drain the rinsing water, etc., which is thrown into the bucket 30 when washing dishes, and to filter food residues, as shown in FIG. 2. A drainage pipe 40 attached to the filter, a filter net 42 detachably embedded in the drainage tank 40 from above the bucket 30, and a lid 44 covering an open upper surface of the drainage reservoir 40. ), A retaining ring 46 attached to the upper surface of the bucket 30 to support the filter network 42, a odor preventing cap 48 built into the drain container 40, and a side surface of the bucket 30. It includes an overflow hose 50 for connecting the drain container 40, and a drain hose 52 connected to the lower end of the drain container (40).

The locking ring 46 is composed of a disk-shaped pressing portion 461, and a screw coupling portion 462 connected to the pressing portion 461, the drain container 40 is the upper surface is open, the side and the lower surface Each of the structure is provided with a screw type opening 401 to communicate with the overflow hose 50 and the drain hose 52, respectively, the filter net 42 is provided with a plurality of holes or slits on the outer peripheral surface In the form of

According to this, the drain unit, the rinsing water is discharged through the drain container 40 when washing dishes, food waste is filtered by the filter net 42 to prevent the drain hose 52 is clogged. do.

The bucket 30 and the drainage unit constituting the sink as described above are supplied in a state in which the sink 30 is integrally assembled and modularized for the convenience of installing the sink. ), And then attaching the locking ring 46 to the bucket 30 so that the screw coupling portion 462 of the bucket protrudes below the bucket 30 through the through hole 30a of the bucket 30, and then the bottom of the bucket 30. Mount the drain container 40 in such a manner as to fasten the upper end of the drain container 40 and the screwing portion 462 of the locking ring 46 from the drain container 40, the drain hose 52 and the overflow hose in the drain container 40 It proceeds in order to connect 50.

At this time, an upper packing 60 is interposed between the locking ring 46 and the upper surface of the bucket 30, and a lower packing 62 is interposed between the drain container 40 and the lower surface of the bucket 30.

Here, the upper and lower packings 60 and 62 are formed in a ring shape having a rectangular cross section and elastically deformable material. The upper packing 60 is bucket 30 by the pressing portion 461 of the locking ring 46. ) Is fixed between the clamping, and the lower packing 62 is also fixed by the coupling force of the bucket 30 and the drain container 40 in a state seated on the top of the drain container 40, respectively, the locking ring 46 and Maintaining airtightness of the portion where the drain container 40 is mounted.

On the other hand, when attaching the drain container 40 to the bucket 30 in the process of assembling the drainage unit as described above, first, the screw engaging portion of the engaging ring 46 in the through hole (30a) of the bucket (30) 462 and the locking ring 46 is to be secured so as not to be pulled out of the screw coupling part 462 and the drain container 40 to be fastened, according to the prior art the lower packing 62 is shown in FIG. Since it is a structure that is simply seated on the top of the sump 40 without any other support means as described above, when mounting the sump 40, not only the locking ring 46, but also the lower packing 62 should be supported.

Therefore, when one worker performs such assembling work, one hand supports the locking ring 46 at one side of the bucket 30, and the other hand has a lower packing 62 and a drain container at the other side of the bucket 30. 40) should be attached, because the weight and size of the bucket 30 is considerable, there are many difficulties.

In order to solve such a difficulty, two workers made a pair, one person supports the retaining ring 46 on one side of the bucket 30, and the other person drains the drain container 40 from the other side of the bucket 30. Sometimes work is assembled.

Therefore, according to the prior art as described above, when one worker assembles the drainage unit, the work efficiency is lowered because the assembling work is difficult, and when working in pairs of two people, the manufacturing cost of the product is increased by increasing the number of assembly labor. There are disadvantages.

The present invention has been made to solve the above-mentioned conventional problems, it is intended to provide a drainage unit of the sink is easy to assemble by the lower packing is made of a structure fixed to the drain container.

In the drainage unit of the sink provided to achieve the above object, a cylindrical inner and outer guide rim having a predetermined height is formed on the upper surface of the drain box, and the lower packing is fitted between the inner and outer guide rims so that the drain and lower packing are integrated. It is characterized in that the configuration.

Here, the lower packing is made of a shape in which the upper and lower thickness slightly exceeds the height of the inner and outer guide rim of the drain container, the contact surface with the bucket is formed in a round shape.

Hereinafter, with reference to the accompanying Figure 4 of an embodiment of the present invention will be described in detail.

Drainage unit according to an embodiment of the present invention is characterized in that the bottom packing 63 is fixed to the drain container 40 as shown in the drawing is composed of the drain container 40 and the lower packing 62 integrally Is done.

Here, the fixing structure of the drain container 40 and the lower packing 62, the inner and outer guide rims (402, 403) of a predetermined height on the upper surface of the drain container 40 is a predetermined interval in the circumferential direction The lower packing 62 is formed in such a manner that the lower packing 62 is fitted between the inner and outer guide rims 402 and 403.

In addition, the lower packing 62 is configured in a form in which the upper and lower thickness slightly exceeds the height of the inner and outer guide rims 402 and 403, the contact surface with the bucket 30 is formed in a round shape.

According to the embodiment of the present invention as described above, it is possible to perform the assembly operation of the drainage unit in a state in which the lower packing 62 is sandwiched between the inner and outer guide rims 402 and 403 of the drain container 40. .

Therefore, in the process of attaching the drain container 40, the hand holds the locking ring 46 fitted to the bucket 30, and lifts the water container 40 with the lower packing 62 attached by the other hand. What is necessary is just to fasten with the ring 46, At this time, since it is not necessary to carry out additional work for supporting the lower packing 62 separately like conventionally, it becomes possible to perform assembly work efficiently enough as a worker.

In addition, according to the present embodiment, when the lower packing 62 is pressed and fixed in contact with the lower surface of the bucket 30, the contact surface is in a round shape, the elastic deformation is larger than the conventional simple rectangular structure is larger than the bucket ( Since the traction with 30) is enhanced, the airtightness of the drain container 40 is also improved.

As described above, according to the drainage unit of the sink according to the present invention, since the lower packing is fixed to the drain container, the efficiency of assembly is increased, and the airtightness of the drain container is enhanced due to the structural characteristics of the lower packing. There is an advantage in helping to improve productivity and marketability.
