Abstract
A cooking appliance capable of preventing a user's unintended rotation of a knob assembly includes: a main body including a control panel; a valve positioned inside the main body, and including a valve shaft being pushable and rotatable; and a knob assembly including an inner knob coupled with the valve shaft, and an outer knob being movable with respect to the inner knob in a first direction in which the outer knob approaches the inner knob, wherein, when the outer knob moves by a first push distance in the first direction, the valve shaft and the inner knob are prevented from rotating.
Claims18
A cooking appliance comprising:
- a main body comprising a control panel;
- a valve positioned inside the main body and comprising a valve shaft being pushable and rotatable;
- and
- a knob assembly comprising:
- an inner knob coupled with the valve shaft, and
- an outer knob being movable in a first direction in which the outer knob approaches the inner knob, the outer knob comprises a threaded boss portion protruding from a top interior surface of the outer knob toward the inner knob,
- wherein, based on the outer knob moving by a first push distance in the first direction, the valve shaft and the inner knob are prevented from rotating.
A cooking appliance comprising:
- a main body comprising a control panel;
- a valve positioned inside the main body and comprising a valve shaft being pushable and rotatable;
- and
- a knob assembly comprising:
- a knob coupled with the valve shaft and configured to push and rotate the valve shaft, and
- a cover knob covering the knob to prevent the knob from being pushed,
- wherein the cover knob comprises a boss protruding toward the knob,
- wherein the boss comprises a screw thread formed in an inner surface of the boss, and
- wherein the knob comprises a boss hole through which the boss passes.
A cooking appliance comprising:
- a valve body;
- a valve shaft being insertable in the valve body and being rotatable with respect to the valve body when being inserted in the valve body;
- and
- a knob assembly coupled with the valve shaft and configured to insert the valve shaft in the valve body and rotate the valve shaft with respect to the valve body, the knob assembly comprising:
- an inner knob coupled with the valve shaft;
- and
- an outer knob movable relative to the inner knob by a first distance, wherein, based on the outer knob moving by less than the predetermined first distance in a direction in which the outer knob approaches the inner knob, the outer knob does not push the inner knob,
- wherein subsequent to the outer knob moving the first distance in the direction in which the outer knob approaches the inner knob, the outer knob is movable a second distance in order to enable rotation of the valve shaft, the second distance being greater than the first distance.
