Abstract

The disclosure relates to a cooking appliance capable of reducing noise generated when a door is closed using a buffer member that is easily fixed to a hinge unit. The cooking appliance includes a main body, a cooking chamber provided to have a front surface opened inside the main body, a door to open and close the cooking chamber, a hinge unit coupled to the main body to rotatably support the door, and a buffer member fixed to the door to buffer an impact generated when the door is closed by contacting the hinge unit when the door is closed.

First claim

The invention claimed is:

1. A cooking appliance comprising:
a main body;
a cooking chamber provided to have a front surface opened inside the main body;
a door to open and close the cooking chamber;
a hinge unit coupled to the main body to rotatably support the door, wherein the hinge unit includes:
a first coupling part coupled to the main body,
a second coupling part coupled to the door and including a fixing hole, and
a hinge part having a side coupled to the first coupling part and another side on which a hinge shaft is provided to allow the second coupling part to be rotatably coupled to the hinge shaft; and

a buffer member including a fixing hook fixed to the fixing hole of the second coupling part and a buffer part to buffer an impact generated when the door is closed by contacting the hinge unit when the door is closed.

2. The cooking appliance according to claim 1 , wherein the buffer part includes:
a support portion supported on the second coupling part, and
a contact portion extending from the support portion to buffer the impact by contacting the hinge part when the door is closed.

3. The cooking appliance according to claim 2 , wherein the contact portion is provided to be bent at an angle of 90 degrees or less with respect to the support portion.

4. The cooking appliance according to claim 3 , wherein the contact portion is provided to be bent at an angle of approximately 15 degrees with respect to the support portion.

5. The cooking appliance according to claim 1 , wherein the buffer part is provided to have a length of approximately 15 mm in a vertical direction.

6. The cooking appliance according to claim 1 , wherein:
a plurality of fixing hooks are provided, and
a number of fixing holes corresponds to a number of the plurality of fixing hooks.

7. The cooking appliance according to claim 6 , wherein the buffer part includes:
a support portion supported on the second coupling part, and
contact portions extending in a direction from left and right ends of the support portion toward the main body to buffer the impact by contacting the hinge part when the door is closed.

8. The cooking appliance according to claim 1 , wherein the buffer member is made of a plastic material.
