Abstract

A cooking apparatus includes a housing, a heat source on one side of the housing, a control panel couplable to the housing, a knob rotatably mountable on the control panel to operate the heat source and movable rearwardly, a stopper between the control panel and the knob and including an anti-rotation portion configured to prevent a rotation of the knob, a button movably couplable to the knob in a left-to-right direction, and a locking pin accommodated in the anti-rotation portion and secured to the button so as to move along the button. The locking pin is deviated from the anti-rotation portion based on movement of the button, the knob is rotatable while the knob is moved rearwardly and the locking pin is deviated from the anti-rotation portion, and the knob is rotated to operate the heat source.

First claim

What is claimed is:

1 . A cooking apparatus, comprising:
a housing; a heat source on one side of the housing; a control panel couplable to the housing; a knob rotatably mountable on the control panel to operate the heat source and movable rearwardly; a stopper between the control panel and the knob, the stopper including an anti-rotation portion configured to prevent a rotation of the knob; a button movably couplable to the knob in a left-to-right direction; and a locking pin accommodated in the anti-rotation portion and secured to the button so as to move along the button; and wherein the locking pin is deviated from the anti-rotation portion based on a movement of the button, the knob is rotatable while the knob is moved rearwardly and the locking pin is deviated from the anti-rotation portion, and the knob is rotated to operate the heat source.

2 . The cooking apparatus of claim 1 , wherein the rotation of the knob is prevented while the locking pin is accommodated in the anti-rotation portion.

3 . The cooking apparatus of claim 2 , wherein
the locking pin is movable between a first pin position in which the rotation of the knob is locked by being accommodated in the anti-rotation portion and a second pin position in which the rotation of the knob is unlocked by being deviated from the anti-rotation portion, and the anti-rotation portion includes a stopper groove in which the locking pin is accommodated at the first pin position of the locking pin, and while the button is moved in the left-to-right direction, the locking pin is moved from the first pin position to the second pin position to allow the locking pin to be deviated from the stopper groove.

4 . The cooking apparatus of claim 3 , wherein
the button is configured to rotate along the knob at the second pin position of the locking pin, after the knob and the button are rotated at a predetermined angle, the locking pin is movable to the first pin position.

5 . The cooking apparatus of claim 4 , wherein the knob and the button are rotatable while the locking pin is at the first pin position after the knob and the button are rotated at the predetermined angle.

6 . The cooking apparatus of claim 3 , wherein the stopper comprises:
a hollow portion; an perimeter wall forming the hollow portion; and a protruding wall protruding from the perimeter wall and on which the stopper groove is formed.

7 . The cooking apparatus of claim 3 , wherein the button comprises:
a first pressing portion and a second pressing portion arranged in one direction; a first rack extending from the first pressing portion toward the second pressing portion; a second rack extending from the second pressing portion toward the first pressing portion; and a pinion disposed between the first rack and the second rack so as to be rotatable based on the first pressing portion and the second pressing portion being pressed.

8 . The cooking apparatus of claim 7 , wherein the button further includes a spring disposed between the first pressing portion and the second pressing portion to press the first pressing portion and the second pressing portion.

9 . The cooking apparatus of claim 8 , wherein
the control panel is disposed on a front side of the housing, and the button further comprises:
a first guide portion extending in left-to-right direction from a rear end of the first pressing portion;
a second guide portion extending in left-to-right direction from a rear end of the second pressing portion; and
a guide groove formed in the first guide portion and the second guide portion in the left-to-right direction to guide the movement of the first pressing portion and the second pressing portion.

10 . The cooking apparatus of claim 9 , further comprising a weight disposed on a front side of the stopper,
wherein the weight comprises:
a base; and
a guide rail protruding from the base toward the button and arranged in the left-to-right direction so as to be inserted into the guide groove.

11 . The cooking apparatus of claim 7 , wherein
the knob includes a receiving space configured to receive the button, and the first pressing portion and the second pressing portion are exposed from the receiving space to be pressed.

12 . The cooking apparatus of claim 7 , further comprising a weight disposed on a front side of the stopper,
wherein the weight comprises:
a base;
a pinion mounting portion protruding from the base to allow the pinion to be mounted; and
a guide hole formed in the base to guide the movement of the locking pin.

13 . The cooking apparatus of claim 12 , further comprising a stopper holder coupled to the control panel to secure the stopper,
wherein the stopper holder comprises:
a fixing portion to which the stopper is secured;
a light source substrate disposed outside the fixing portion and electrically connected to a light source; and
a light diffusion portion disposed outside the fixing portion to diffuse light emitted from the light source.

14 . The cooking apparatus of claim 1 , wherein
the control panel is configured to partially cover a front side of the housing, and the knob is movable between a first knob position and a second knob position moved rearwardly from the first knob position, and the cooking apparatus further comprises: a regulator disposed on a rear side of the control panel to operate the heat source in response to the rotation of the knob; a shaft coupled to the regulator to be movable from a first shaft position in which rotation with respect to the regulator is restricted at the first knob position of the knob to a second shaft position rotatable with respect to the regulator at the second knob position so as to operate the heat source; a fixing protrusion protruding from the shaft in a radial direction of the shaft; and a fixing groove formed in the regulator to receive the fixing protrusion while the shaft is positioned at the first shaft position, wherein, based on the knob being moved toward the control panel, the shaft is moved to the second shaft position.

15 . The cooking apparatus of claim 14 , further comprising a processor configured to control the regulator to generate a signal based on the rotation of the knob, and to operate the heat source in response to the signal generated by the regulator.

16 . A cooking apparatus, comprising:
a housing; a heat source on one side of the housing; a control panel coupled to the housing; a knob rotatably mounted on the control panel so as to operate the heat source; a button movably coupled to the knob; a stopper between the control panel and the button and including an anti-rotation portion configured to prevent a rotation of the knob; and a locking pin secured to the button so as to be received in the anti-rotation portion and configured to prevent the rotation of the knob while the locking pin is received in the anti-rotation portion.

17 . The cooking apparatus of claim 16 , wherein the knob is movable between a first knob position in which rotation is prevented, and a second knob position moved in a first direction from the first knob position, the button is movable in a direction different from the first direction between a first button position in which the pin is locked by the stopper to prevent the rotation of the knob, and a second button position in which the pin is unlocked from the stopper, and based on the knob being at the second knob position and the button being at the second button position, the knob is rotated to operate the heat source.
