A knob ring assembly for an appliance, comprising:
- a knob ring that is configured to be disposed at a front surface of a front panel of the appliance and to circumferentially surround a knob of the appliance, the knob ring being configured to rotate independently of a rotation of the knob;
- an actuating member that is configured to be provided at a rear side of the front panel, the actuating member being fixed to the knob ring through the front panel and configured to rotate integrally with the knob ring relative to the knob;
- a support frame that is configured to be fastened at a rear surface of the front panel and to rotatably support the actuating member;
- a spacing plate that is configured to be positioned between the knob ring and the front panel to thereby maintain a preset separation distance between the knob ring and the front panel, the knob ring being fixed to the actuating member through the spacing plate;
- and
- a spacing member that is inserted between the actuating member and the support frame,
- wherein the spacing plate and the spacing member are integrally formed.
A knob ring assembly for an appliance, comprising:
- a knob ring that is configured to be disposed at a front surface of a front panel of the appliance and to circumferentially surround a knob of the appliance, the knob ring being configured to rotate independently of a rotation of the knob;
- an actuating member that is configured to be provided at a rear side of the front panel, the actuating member being fixed to the knob ring through the front panel and configured to rotate integrally with the knob ring relative to the knob;
- and
- a spacing plate that is configured to be positioned between the knob ring and the front panel to thereby maintain a preset separation distance between the knob ring and the front panel, the knob ring being fixed to the actuating member through the spacing plate,
- wherein the knob ring includes:
- an inner circular plate area that receives a front end of the actuating member, and
- an outer circular plate area that is arranged radially outward from the inner circular plate area,
- wherein the actuating member is fixed to the knob ring at a rear of the inner circular plate area,
- wherein a front surface of the spacing plate faces the outer circular plate area, and
- wherein the outer circular plate area is recessed and the spacing plate is received inside the outer circular plate area.
