Abstract
A control unit for a cooking appliance including a base configured to be coupled to a cooking appliance, a knob rotatably disposed at the base, and a cover ring coupled to the base to surround the base. The cover ring may be mounted on the base by rotating the cover ring in a first direction with respect to the base, and removed from the base by rotating the cover ring in a second direction, which is an opposite direction to the first direction.
Claims17
A control unit for a cooking appliance, comprising:
- a base configured to be coupled to the cooking appliance;
- a knob rotatably disposed at the base;
- and
- a cover ring coupled to the base to surround the base, wherein the cover ring is mounted on the base by rotating the cover ring in a first direction with respect to the base, and is removed from the base by rotating the cover ring in a second direction, which is an opposite direction to the first direction, wherein the base has at least one coupling protrusion that protrudes outwardly from an edge of the base and to which the cover ring is coupled, wherein the cover ring comprises:
- a first coupling groove, which is formed on an inner wall of the cover ring, a first end of which is open, and to which the at least one coupling protrusion is coupled;
- and
- a second coupling groove, which is formed on the inner wall of the cover ring, which connects to the first coupling groove, a lengthwise direction of which is disposed in a circumferential direction of the cover ring, and to which the at least one coupling protrusion is coupled, and wherein the cover ring comprises a restriction projection that is formed at a position of the cover ring at which the second coupling groove is formed, wherein the restriction projection protrudes from the inner wall of the cover ring, and wherein the restriction projection suppresses movement of the at least one coupling protrusion at the second coupling groove.
