Abstract: A cooking appliance may include a panel provided with a through hole; a knob assembly installed at the panel; and a valve disposed inside of the panel. The knob assembly may include a shaft that passes through the through hole, configured to move in an axial direction between a first axial position and a second axial position and rotate around a rotational center; a knob disposed outside of the panel, connected to the shaft, and configured to move with the shaft in the axial direction and rotate with the shaft; a frame installed at the panel and configured to support rotation of the shaft; a rotational member connected to the shaft, configured to move and rotate with the, and having a diameter larger than a diameter of the shaft; a first rotation limiting portion provided on the frame at a first circumferential position; a second rotation limiting portion provided to the rotational member at a second circumferential position, engaged with the first rotation limiting portion at the first axial position and interfering therewith in the circumferential direction in a state in which the first circumferential position and the second circumferential position correspond to each other, and disengaged from the first rotation limiting portion at the second axial position and not interfering therewith the circumferential direction; and an elastic member configured to elastically support the shaft.

Abstract: A cooking appliance is provided that may include a main body having a cavity, and a door that opens and closes the cavity. The door may include a display module including a display unit disposed in a front of the door, a cooling flow path disposed behind the display module, and having a flow path formed therein through which air for cooling flows, and a shielding unit disposed behind the cooling flow path, and configured to shield electromagnetic waves generated in the main body. The display module may include the display unit on which videos or images are displayed, and an outer panel disposed behind the display unit, and on which the display unit is mounted. The cooling flow path may include an inner panel disposed behind the outer panel and mounted on the outer panel, and an air guide disposed between the outer panel and the inner panel and coupled to the inner panel.
