Abstract

A cooking appliance includes a packing member disposed between a case and a door and a fixing member which fixes the packing member to any one of the case and the door. The packing member and the fixing member are coupled in the form in which both sides in a front-rear direction of the fixing member inserted into the packing member are surrounded by the packing member.

First claim

What is claimed is:

1. A cooking appliance comprising:
a case that defines a cooking chamber and an opening at a front of the cooking chamber;
a door disposed at a front of the case and configured to open and close the opening;
a front panel disposed between the case and the door;
a packing member disposed between the case and the door; and
a fixing member that couples the packing member to the case or the door,
wherein the fixing member and the packing member are coupled to the front panel, and
wherein the packing member comprises:
a first packing part that surrounds the opening of the case and receives at least a part of the fixing member,
a second packing part that protrudes from the first packing part toward one of the door or the cooking chamber, and
a coupling protrusion coupled to the front panel.

2. The cooking appliance of claim 1 , wherein the fixing member comprises:
a first fixing part inserted into the first packing part; and
a second fixing part connected to the first fixing part and coupled to the case or the door, and
wherein the first packing part defines an insertion portion that is recessed into an inside of the first packing part and receives at least a part of the first fixing part.

3. The cooking appliance of claim 2 , wherein the insertion portion receives the first fixing part such that a front side and a rear side of the first fixing part are covered by the first packing part.

4. The cooking appliance of claim 2 , wherein the insertion portion comprises:
a first insertion portion recessed from a first surface of the first packing part, the first insertion portion extending in a first direction toward the inside of the first packing part; and
a second insertion portion connected to the first insertion portion and further recessed into the inside of the first packing part in a second direction different from the first direction, the second insertion portion being spaced apart from the first surface of the first packing part by a predetermined distance.

5. The cooking appliance of claim 4 , wherein the second insertion portion receives the first fixing part such that a front side and a rear side of the first fixing part are covered by the first packing part, and
wherein the first insertion portion passes through the first surface of the first packing part and is open toward the second fixing part.

6. The cooking appliance of claim 4 , wherein the first surface is a rear surface of the first packing part, the first insertion portion being recessed from the rear surface of the first packing part in a forward direction, and
wherein the second insertion portion is recessed from a front end portion of the first insertion portion in a direction parallel to the rear surface of the first packing part.

7. The cooking appliance of claim 4 , wherein the first insertion portion and the second insertion portion are connected to each other and define an “L” shape.

8. The cooking appliance of claim 4 , wherein the second insertion portion is spaced apart from the first surface of the first packing part by 0.5 mm or more.

9. The cooking appliance of claim 4 , wherein at least a part of the second fixing part is inserted into of the first insertion portion and has a shape corresponding to a shape of the first insertion portion, the second fixing part being connected to the first fixing part that is inserted in the second insertion portion, and
wherein the first fixing part extends from the second fixing part parallel to a direction in which the second insertion portion is recessed from the first insertion portion.

10. The cooking appliance of claim 9 , wherein the first packing part has an inner surface that is in contact with and presses a front surface and a rear surface of the first fixing part that is inserted into the second insertion portion, and
wherein the first fixing part is fixed to the inner surface of the first packing part.

11. The cooking appliance of claim 9 , wherein the packing member and the fixing member are integrally molded by injection molding in a state in which the first fixing part is inserted into the first packing part.

12. The cooking appliance of claim 1 , wherein the fixing member comprises a hook that has a curved shape and couples the packing member to the front panel.

13. The cooking appliance of claim 1 , wherein the front panel defines a guide hole and a coupling hole that pass through the front panel in a front-rear direction,
wherein the fixing member is inserted into the guide hole and curved to couple the packing member to the front panel,
wherein the coupling protrusion is inserted into the coupling hole to couple the packing member to the front panel, and
wherein the coupling hole faces the coupling protrusion in the front-rear direction.

14. The cooking appliance of claim 13 , wherein a size of the guide hole is greater than a thickness of the fixing member.

15. The cooking appliance of claim 14 , wherein the first packing part covers a space outside the fixing member in the guide hole.

16. The cooking appliance of claim 13 , wherein the coupling protrusion extends along a portion of a perimeter of the first packing part, and the coupling hole extends along a side of the front panel.

17. The cooking appliance of claim 1 , wherein the second packing part protrudes from the first packing part toward the cooking chamber, and
wherein the packing member further comprises a third packing part that protrudes from the first packing part toward the door.

18. The cooking appliance of claim 1 , wherein a heat resistance of the packing member is greater than a heat resistance of silicone rubber.

19. The cooking appliance of claim 1 , wherein the packing member is made of a fluorine rubber material.
