Abstract
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.

A knob assembly, comprising:
- a knob ring configured to be rotatable at a front of a front panel;
- a support frame non-rotatably attached to a rear of the front panel;
- an actuating ring provided at the rear of the front panel, rotatably supported by the support frame, and coupled to the knob ring through the front panel to be rotated by interlocking with rotation of the knob ring;
- and
- at least one spring connected to the support frame and the actuating ring and configured to provide an elastic force when the knob ring is rotated in one of a clockwise or counterclockwise direction from an initial position so as to return the knob ring toward the initial position when an external force is released.
A cooking appliance, comprising:
- a front panel;
- and
- at least one knob configured to be rotatable at a first side of the front panel;
- at least one knob ring provided at the first side of the front panel and configured to surround the at least one knob so as to be rotated independently from the at least one knob;
- an actuating ring provided at a second side of the front panel and coupled to the knob ring through the front panel to be rotated by interlocking with rotation of the knob ring;
- and
- a support frame provided at the second side of the front panel, configured to rotatably support the actuating ring, and coupled to the front panel at the second side of the front panel;
- and
- at least one spring connected to the support frame and the actuating ring and configured to provide an elastic force when the knob ring is rotated in one of a clockwise or counterclockwise direction from an initial position so as to return the knob ring toward the initial position when an external force is released.
