Abstract

The present disclosure relates to a cooking apparatus including a knob assembly used to operate the cooking apparatus.The cooking apparatus includes a main body comprising a control panel, a valve disposed inside the main body and comprising a valve shaft configured to be movable, and a knob assembly comprising a knob cover rotatably disposed on the control panel, and a knob body configured to be pushed separately from the knob cover to push the valve shaft so that the valve shaft is prevented from being pushed by the knob cover.

First claim

The invention claimed is:

1. A cooking apparatus comprising:
a main body comprising a control panel;
a valve disposed inside the main body and comprising a valve shaft configured to be movable; and
a knob assembly comprising a knob cover rotatably disposed on the control panel, a knob body configured to be pushed separately from the knob cover to push the valve shaft so that the valve shaft is prevented from being pushed by the knob cover, and a coupling member configured to couple the knob cover and the knob body so that the knob body is movable,
wherein the coupling member comprises a coupling portion coupled to the knob cover and a head portion configured to restrict the movement of the knob body.

2. The cooking apparatus according to claim 1 , wherein:
the knob cover comprises a cover body configured such that a portion of the knob body is accommodated and a cover handle extending from the cover body to be gripped by a user; and
the knob assembly further comprises a knob base disposed near the cover body to prevent the knob cover from being pushed.

3. The cooking apparatus according to claim 2 , wherein
a distance by which one end of the cover body is spaced apart from one end of the knob base facing the one end of the cover body is shorter than a distance to which the valve shaft is moved to open the valve.

4. The cooking apparatus according to claim 1 , wherein:
the head portion is spaced apart from a body hole of the knob body configured such that the coupling member passes therethrough.

5. The cooking apparatus according to claim 4 , wherein:
the knob body comprises a body portion covered by a cover body and a push portion extending from the body portion; and
the knob assembly further comprises an elastic member disposed near the push portion so that the knob body pulls the valve shaft.

6. The cooking apparatus according to claim 5 , wherein
the elastic member is disposed between the head portion and one end portion of the push portion facing each other.

7. The cooking apparatus according to claim 6 , wherein
the elastic member and the head portion are accommodated in the knob body.

8. The cooking apparatus according to claim 5 , wherein
the coupling member further comprises a guide portion provided between the coupling portion and the head portion to guide the movement of the knob body.

9. The cooking apparatus according to claim 8 , wherein
the elastic member is disposed on the guide portion.

10. The cooking apparatus according to claim 2 , wherein
a distance by which one end of the cover handle is spaced apart from one end of the knob body facing the one end of the cover handle is longer than a distance by which one end of the cover body is spaced apart from one end of the knob base facing the one end of the cover body.

11. The cooking apparatus according to claim 2 , wherein
a distance by which one end of the cover body is spaced apart from one end of the knob base facing the one end of the cover body is longer than a distance to which the valve shaft is moved to open the valve.

12. The cooking apparatus according to claim 2 , wherein
the knob assembly further comprises an elastic member disposed between the cover handle and one end of the knob body facing each other.

13. The cooking apparatus according to claim 1 , wherein
the knob cover comprises a touch portion configured to control the valve shaft to be pushed by the knob cover.
