Abstract

In one aspect, a cooking appliance includes a cabinet forming a cavity configured to provide a food accommodation space; at least one door covering the cavity; a handle rotatably coupled to the door; and a handle supporter disposed inside the door and configured to rotatably support the handle relative to the door. In another aspect, a cooking appliance includes a drawer configured to be withdrawn from or inserted into the cooking appliance; a first rail disposed on the drawer; a second rail disposed on a frame of the cooking appliance and configured to accommodate a sliding motion of the first rail; a link component disposed at the first rail; a sliding control assembly disposed at the second rail and configured to accommodate the link component to automatically insert the drawer into the frame and to mitigate an impact of the drawer being fully inserted into the frame.

First claim

What is claimed is:

1. A cooking appliance comprising:
a drawer defining an accommodation space and configured to be withdrawn or inserted;
a first rail provided at both sides of the drawer;
a link component provided at a first side of the first rail and configured to move along with the first rail;
a frame configured to accommodate the drawer;
second rails provided at both sides of the frame and configured to slidably accommodate the first rail;
a sliding control assembly provided at the second rails and selectively connected to the link component based on the drawer being withdrawn or inserted,
wherein the sliding control assembly includes:
a housing;
a hook configured to move along the housing and coupled to the link component; and
an elastic member configured to connect the hook and a first side of the housing and to be tensioned based on the hook moving forward to provide elastic force for automatic insertion of the drawer,

wherein the link component includes:
a recessed part recessed to receive a first side of the hook; and
connecting parts protruding at both sides of the recessed part,

wherein, based on the drawer being inserted, the sliding control assembly is connected to the link component such that the drawer is automatically inserted,
wherein, based on the drawer being withdrawn, the drawer is disconnected from the link component such that drawer is smoothly withdrawn.

2. The cooking appliance according to claim 1 ,
wherein the housing is provided with a damper disposed in parallel to the elastic member, and
wherein the damper includes a rod rotatably coupled to the hook.

3. The cooking appliance according to claim 1 ,
wherein the hook is provided with a stopper protruding therefrom, and
wherein the sliding control assembly includes a guide unit that is configured to accommodate the stopper and that extends by a length and in a direction corresponding to a movement stroke of the hook.

4. The cooking appliance according to claim 1 , wherein a locking protrusion configured to move along a first surface of the housing based on a movement of the hook is provided at a second side of the hook.

5. The cooking appliance according to claim 4 , wherein the housing includes:
guide surfaces configured to guide movement of the hook in contact with the locking protrusion based on the housing moving; and
a locking groove that is configured to extend to have a slope at front ends of the guide surfaces and that is configured to accommodate the locking protrusion such that the hook rotates.

6. The cooking appliance according to claim 5 ,
wherein the guide surfaces include:
a first surface parallel to the second rails, and
a second surface obliquely provided between the first surface and the locking groove,
wherein the slope of the locking groove is greater than a slope of the second surface.

7. The cooking appliance according to claim 5 , wherein the hook includes:
a hook groove recessed to accommodate and engage the link component;
a front contact portion defining a first half of the hook at a front end of the hook groove; and
a rear contact portion defining a second half of the hook at a rear end of the hook groove.

8. The cooking appliance according to claim 7 , wherein, in a state in which the locking protrusion is accommodated in the locking groove, the hook groove faces forward such that the link component enters or exits the hook groove.

9. The cooking appliance according to claim 7 , wherein, in a state in which the locking protrusion is accommodated and rotated in the locking groove, the front contact portion is located inside the housing and the rear contact portion protrudes to the outside of the housing.

10. The cooking appliance according to claim 1 , wherein the link component extends in a direction crossing an extension direction of the first rail and extends by a length capable of being engaged with the hook based on the first rail moving forward and backward.

11. The cooking appliance according to claim 1 , wherein a connecting hole recessed in a surface facing the hook such that a front end of the hook is inserted is defined at each of the connecting parts.

12. The cooking appliance according to claim 11 ,
wherein tips protruding inward are formed at an opened inlet side of the connecting hole, and
wherein a distance between the tips is less than a thickness of the front end of the hook such that the front end of the hook is pressed into the connecting hole.

13. The cooking appliance according to claim 12 , wherein the tips are facing each other.

14. The cooking appliance according to claim 12 , wherein the tips are vertically extending along an opening of the connecting hole and tilted toward an inner portion of the connecting hole.

15. The cooking appliance according to claim 11 ,
wherein the hook includes:
a hook groove recessed such that the connecting parts are inserted;
a front contact portion protruding from the front end of the hook groove to be in contact with one inner side surface of the recessed part; and
a rear contact portion protruding from the rear end of the hook groove to be in contact with the other inner side surface of the recessed part,
wherein the thickness of the rear contact portion is greater than a thickness of the front contact portion and a width between the connecting holes.

16. The cooking appliance according to claim 1 ,
wherein the frame includes:
a front frame forming an opening into which the drawer is inserted; and
side frames extending from both sides of the front frame backward,
wherein the second rails are mounted in the front frame and extend in parallel to the side frames.

17. The cooking appliance according to claim 16 ,
wherein a cover configured to cover the drawer from the top is fixed to and mounted at an upper end of the front frame,
wherein a supporter configured to support the cover is provided at rear half of each of the side frames, and
wherein front ends of the second rails are fixed to the front frame and the rear ends of the second rails are fixed to the supporter.

18. The cooking appliance according to claim 16 , wherein the cooking appliance is mounted in an outer case forming appearance of the cooking appliance of the frame.

19. The cooking appliance according to claim 18 ,
wherein the frame is provided at a lower end of the cooking appliance, and
wherein legs which are in contact with a floor surface where the cooking appliance is mounted are provided at the side frames.

20. The cooking appliance according to claim 1 , wherein the first rail has a structure extending in multiple stages.
