Abstract

The present disclosure relates to a cooking appliance. In the cooking appliance, a portion of a fastening bracket is coupled to a cabinet, the remaining portion of the fastening bracket contacts the bottom surface of a housing in parallel, and as a fastening member couples the fastening bracket to the bottom surface of the housing, the cabinet is coupled to the housing while the front surface of the cabinet contacts the housing closely.

First claim

What claimed is:

1 . A cooking appliance, comprising:
a housing having a cooking space defined by a bottom surface, a rear surface and a pair of lateral surfaces of the housing, and having an open upper surface and an open front surface; a door to open and close the open upper surface and the open front surface of the housing; a pair of hinge assemblies, each disposed outside a respective lateral surface of the pair of lateral surfaces of the housing and supporting the door while enabling the door to swivel; a cabinet comprising a rear surface covering part disposed behind the rear surface of the housing, a pair of lateral surface covering parts disposed outside the pair of lateral surfaces of the housing, and a front surface covering part disposed in front of the respective hinge assemblies; and
a cabinet fixing part limiting a front-to-rear position of the front surface covering part and coupling the cabinet to the housing,
wherein the cabinet fixing part comprises:
a fastening bracket which is coupled to the cabinet and at least a portion of which contacts the bottom surface of the housing in parallel; and a fastening member coupling the fastening bracket to the bottom surface of the housing,
wherein the cabinet comprises a lower end extension part that extends from a lower end of the front surface covering part in a parallel direction with the bottom surface of the housing, and
the fastening bracket is coupled to the lower end extension part and passes through the lower end extension part in an up-down direction.

2 . The cooking appliance of claim 1 , wherein a bracket fitting hole is formed that penetrates in the up-down direction at the lower end extension part, and
the fastening bracket is coupled to the lower end extension part through the bracket fitting hole.

3 . The cooking appliance of claim 2 , wherein the fastening bracket comprises:
a fastening surface part that forms a flat surface contacting the bottom surface of the housing in parallel and is coupled by the fastening member; and a fitting part that extends from the fastening surface part and is coupled to the lower end extension part through the bracket fitting hole.

4 . The cooking appliance of claim 3 , wherein the fastening member couples the fastening surface part to the bottom surface of the housing while passing through the fastening surface part and the bottom surface of the housing in the up-down direction.

5 . The cooking appliance of claim 3 , wherein a maximum length of the bracket fitting hole is less than a minimum length of the fastening surface part, and a length of the fitting part is a length of the bracket fitting hole or less, in a lateral direction.

6 . The cooking appliance of claim 3 , wherein the fitting part comprises:
a first fitting part that extends from the fastening surface part in a parallel direction with the direction in which the bracket fitting hole penetrates; and a second fitting part that extends at a slant in a front-rear direction while extending upward from the first fitting part.

7 . The cooking appliance of claim 6 , wherein a front-to-rear position and a left-to-right position of the fastening bracket are regulated while the second fitting part is fitted to the lower end extension part through the bracket fitting hole.

8 . The cooking appliance of claim 6 , wherein an up-to-down position of the fastening bracket is regulated while the lower end extension part is fitted between the fastening surface part being disposed under the lower end extension part and the second fitting part protruding from an upper portion of the lower end extension part and into the bracket fitting hole.

9 . The cooking appliance of claim 7 , wherein the second fitting part passes through the lower end extension part through the bracket fitting hole and protrudes from the upper portion of the lower end extension part, and
a length of a front-to-rear range occupied by the second fitting part is greater than a front-to-rear length of the bracket fitting hole, on the lower end extension part.

10 . The cooking appliance of claim 7 , wherein the second fitting part extends from the first fitting part at a slant in a direction between an upward direction and a rearward direction, passes through the lower end extension part through the bracket fitting hole, and protrudes from the upper portion of the lower end extension part, and
an upper end of the second fitting part protruding from the upper portion of the lower end extension part is disposed further rearward than the bracket fitting hole.

11 . The cooking appliance of claim 7 , wherein the fastening surface part is coupled to the bottom surface of the housing by the fastening member that passes through the fastening surface part and the bottom surface of the housing in the up-down direction.

12 . The cooking appliance of claim 11 , wherein as the fastening surface part and the bottom surface of the housing are coupled, an up-to-down position of the lower end extension part is regulated relative to the bottom surface of the housing, and
as the fitting part and the lower end extension part are coupled, the front-to-rear position of the front surface covering part is regulated relative to the front surface.

13 . The cooking appliance of claim 11 , wherein an up-to-down length of the first fitting part is equal to a total of an up-to-down length of an area of the bottom surface of the housing, being disposed between the lower end extension part and the fastening surface part, and an up-to-down length of the fastening surface part.

14 . The cooking appliance of claim 11 , wherein a front-to-rear length of the first fitting part is equal to the front-to-rear length of the bracket fitting hole.
