Abstract

The present disclosure relates to a cooking appliance. In the cooking appliance, a hinge coupling part being fixed to a door and coupled to a hinge part is provided with a position adjustment guide part that guides a front-to-rear coupling position between a fastening part and the hinge coupling part, and the fastening part is coupled to the position adjustment guide part in a way that can move in the front-rear direction and is coupled to the hinge coupling part.

First claim

What is claimed is:

1. A cooking appliance, comprising:
a housing having a cooking space defined by a bottom surface, two lateral surfaces and a rear surface of the housing, and having an open upper surface and an open front surface;
a door capable of swiveling about a rear side of the housing to open and close the open upper surface and the open front surface of the housing;
a hinge part to allow the door to be swivably supported by the housing;
a hinge coupling part disposed at the door to couple to the hinge part; and
a fastening part to couple the hinge part to the hinge coupling part,
wherein the hinge coupling part includes a position adjustment guide part that guides a front-to-rear coupling position between the fastening part and the hinge coupling part, and
the fastening part is coupled to the position adjustment guide part in a way movable in a front-rear direction, and coupled to the hinge coupling part.

2. The cooking appliance of claim 1 , wherein the fastening part comprises a bolt member that passes through the hinge part and a coupling surface of the hinge coupling part in an up-down direction, and a nut member that is coupled to the bolt member and fixes the hinge part to the coupling surface of the hinge coupling part, and
the fastening part is coupled to the position adjustment guide part.

3. The cooking appliance of claim 2 , wherein the hinge coupling part comprises the coupling surface that forms a surface facing the hinge part in the up-down direction, and a fastening hole that penetrates the coupling surface in the up-down direction,
wherein the bolt member passes through the coupling surface through the fastening hole in the up-down direction; and
the position adjustment guide part comprises a fastening hole that has a front-to-rear length greater than a diameter of the bolt member.

4. The cooking appliance of claim 3 , wherein the position adjustment guide part further comprises a fastening and guiding groove that is recessed from a surface opposite from the coupling surface of the hinge coupling part, and
at least a portion of the nut member is disposed in the fastening and guiding groove.

5. The cooking appliance of claim 4 , wherein a front-to-rear length of the fastening and guiding groove is greater than a maximum diameter of the nut member.

6. The cooking appliance of claim 5 , wherein the at least a portion of the nut member is disposed in to the fastening and guiding groove movable in a front-rear direction.

7. The cooking appliance of claim 6 , wherein the nut member is formed as a polygonal pillar, and
the fastening and guiding groove interferes with the nut member to limit a rotation of the nut member.

8. The cooking appliance of claim 1 , wherein the cooking appliance comprises a door frame coupled under the door, and
the hinge coupling part is disposed at the door frame.

9. The cooking appliance of claim 8 , wherein the door comprises:
a door upper surface part to cover the open upper surface of the housing, and
a door front surface part connected to a front side of the door upper surface part to cover the open front surface of the housing.

10. The cooking appliance of claim 9 , wherein the door swivels around a rear side of the door upper surface part to open and close the open upper surface and the open front surface of the housing.

11. The cooking appliance of claim 9 , wherein the cooking appliance comprises a first heating part that is disposed at the door; and
the door frame comprising a heater mounting part to which the first heating part is mounted, and a coupling part that is coupled to the door upper surface part and allows the heater mounting part to be supported by the door upper surface part.

12. The cooking appliance of claim 11 , wherein the hinge coupling part is disposed at the coupling part.

13. The cooking appliance of claim 11 , wherein the fastening part comprises a bolt member that couples the hinge part to the door frame while passing through the hinge part and the coupling surface of the hinge coupling part in the up-down direction, and a nut member that is coupled to the bolt member and fixes the hinge part to the coupling surface of the hinge coupling part, and
the fastening part is coupled to the position adjustment guide part.

14. The cooking appliance of claim 13 , wherein the bolt member and the nut member are coupled in a state in which a head of the bolt member is disposed under the coupling surface of the hinge coupling part and the nut member is disposed on a surface opposite to the coupling surface of the hinge coupling part; and
the position adjustment guide part further comprises a fastening and guiding groove that is recessed from the surface opposite to the coupling surface of the hinge couple part,
wherein at least a portion of the nut member is disposed in the fastening and guiding groove.

15. The cooking appliance of claim 14 , wherein the fastening and guiding groove and the nut member are disposed in a space between the door upper surface part and the door frame, and the bolt member passes through the coupling surface of the hinge coupling part upward and is coupled to the nut member in the space between the door upper surface part and the door frame.

16. The cooking appliance of claim 1 , wherein depending on a front-to-rear position of the fastening part being coupled to the position adjustment guide part, a gap between the front surface of the housing and the door front surface part is adjusted.
