摘要： A knob assembly and an appliance having a knob assembly are provided. The knob assembly may include a knob configured to be rotatably installed, a knob ring configured to surround the knob and to be rotated independently from the knob, a spring configured to provide an elastic force so as to return the knob ring toward an initial position when the knob ring is rotated to a position spaced apart from the initial position, and a magnetic force provider configured to provide a magnetic force to return the knob ring to the initial position when the knob ring is at a position adjacent to the initial position.

摘要： A knob assembly and a cooking apparatus including a knob assembly are provided. The knob assembly may reduce defects in assembly and operation of the knob assembly caused by a tolerance of a valve shaft. The knob assembly may include a valve in which a valve shaft may be movable, a knob connected to a knob shaft coupled with the valve shaft, a knob ring that surrounds a periphery of the knob and supports the knob shaft, a support ring coupled with the knob ring, a support frame that supports an outer circumferential surface of the support ring, and a fixing frame coupled with the support frame to prevent the support ring from separating from the support frame.
