Abstract

A sealing apparatus seals between a pump chamber and a bottom surface of a washing tank of a dishwasher. The sealing apparatus includes a packing member disposed along a top portion of the pump chamber and a protecting member which fixes some portion of the packing member to the pump chamber to prevent the packing member from moving when the bottom surface of the washing tank and the pump chamber are coupled to each other.

First claim

What is claimed is:

1. A sealing apparatus that seals between a pump chamber and a bottom surface of a washing tank of a dishwasher, the sealing apparatus comprising:
a packing member disposed along a top portion of the pump chamber; and
a protecting member which connects some portion of the packing member to the pump chamber such that it prevents the packing member from moving when the bottom surface of the washing tank and the pump chamber are coupled to each other,
wherein at least one discharge passage is formed between the packing member and the protecting member and the at least one discharge passage guides water from an outer surface of the bottom surface of the washing tank to a channel formed in the pump chamber.

2. The sealing apparatus of claim 1 , wherein the protecting member is detachably coupled to the pump chamber.

3. The sealing apparatus of claim 2 , wherein the protecting member comprises a plurality of hooks that are snap-coupled to a portion of the pump chamber.

4. The sealing apparatus of claim 3 , wherein the protecting member comprises:
a first portion that covers an upper portion of the packing member; and
a second portion comprising the plurality of hooks.

5. The sealing apparatus of claim 4 , wherein the first portion comprises an inclined surface that corresponds to a slope of the bottom surface of the washing tank.

6. The sealing apparatus of claim 4 , wherein the second portion is disposed on an outer circumference of the top portion of the pump chamber.

7. The sealing apparatus of claim 4 , wherein the first portion comprises the at least one discharge passage.

8. The sealing apparatus of claim 7 , wherein the at least one discharge passage comprises at least one drain hole that passes through the first portion of the protecting member.

9. The sealing apparatus of claim 7 , wherein the at least one discharge passage comprises a cutting groove that is cut from a step portion formed in a bottom surface of the first portion.

10. The sealing apparatus of claim 1 , wherein:
the packing member comprises a hooking portion that extends from the packing member and is operable to be disposed around the channel of the pump chamber, and
the protecting member comprises a first portion to cover the hooking portion and a second portion that comprises a plurality of hooks operable to be snap-coupled to a portion of the pump chamber.

11. A dishwasher comprising:
a main body comprising a washing tank which receives things to be washed and a pump chamber connected with a bottom surface of the washing tank such that fluid can pass between the washing tank and the pump chamber;
a door that opens and closes the washing tank; and
a sealing apparatus for sealing the pump chamber and the bottom surface of the washing tank, wherein the sealing apparatus comprises:
a packing member disposed along a top portion of the pump chamber; and
a protecting member that connects some portion of the packing member to the pump chamber such that the packing member is prevented from moving when the bottom surface of the washing tank and the pump chamber are coupled to each other, and

wherein at least one discharge passage is formed between the packing member and the protecting member and the at least one discharge passage guides water from an outer surface of the bottom surface of the washing tank to a channel formed in the pump chamber.

12. The dishwasher of claim 11 , wherein
the protecting member comprises:
a first portion that covers an upper portion of the packing member; and
a second portion comprising a plurality of hooks that are operable to be detachably coupled to the pump chamber.

13. The dishwasher of claim 12 , wherein the first portion comprises at least one drain hole operable to guide water from an outer surface of the bottom surface of the washing tank to a channel formed in the pump chamber.

14. The dishwasher of claim 12 , wherein the first portion comprises a cutting groove that is cut from a step portion formed in a bottom surface of the first portion, the cutting groove operable to guide water from an outer surface of the bottom surface of the washing tank to a channel formed in the pump chamber.

15. The dishwasher of claim 11 , wherein
the packing member comprises a hooking portion that is operable to be disposed around a channel of the pump chamber, the hooking portion extending from the packing member, and
the protecting member connects to the hooking portion such that the hooking portion is prevented from moving.
