Abstract
The present invention relates to a cooking appliance. The cooking appliance according to the present invention may have a cavity (S) formed inside cases (100 and 200), and a first heat source module (400) which emits microwaves may be disposed on the side surface of the cases (100 and 200). A second heat source module (600) which generates radiant heat may be disposed on the upper portion of the cases (100 and 200). In addition, it is possible to elevate the second heat source module (600), and whether the first heat source module (400) operates may be determined according to whether the second heat source module (600) is elevated.
Claims17
A cooking appliance comprising:
- a casing having a cavity therein;
- a door provided at the casing, and configured to open and close the cavity;
- a first heat source module arranged at a side surface of the casing;
- a second heat source module arranged at an upper portion of the casing;
- and
- a processor controlling operations of the first and second heat source modules,
- wherein the second heat source module comprises a fixed assembly fixed to the upper portion of the casing, a moving assembly with a heating unit emitting heat, and a link assembly connected to the fixed assembly and the moving assembly while being located therebetween and configured to raise and lower the moving assembly.
A control method of a cooking appliance comprising a first heat source module and a second heat source module, which are respectively provided at a side surface and an upper portion of a casing having a cavity therein, the control method comprising:
- inputting an operation command of the first heat source module;
- determining whether the second heat source module is raised or lowered;
- and
- when the second heat source module is raised to a preset initial position, operating the first heat source module.
A control method of a cooking appliance comprising a first heat source module and a second heat source module, which are respectively provided at a side surface and an upper portion of a casing having a cavity therein, the control method comprising:
- raising the second heat source module to a preset initial position and allowing the second heat source module to wait;
- inputting a lowering command of the second heat source module;
- determining whether or not the first heat source module is operated;
- and
- when the first heat source module is operated, allowing the second heat source module to continue to wait at the initial position, and when the first heat source module is in a non-operated state, lowering the second heat source module.
A control method of a cooking appliance comprising a first heat source module and a second heat source module, which are respectively provided at a side surface and an upper portion of a casing having a cavity therein, the control method comprising:
- raising the second heat source module to a preset initial position and allowing the second heat source module to wait;
- inputting a lowering command of the second heat source module;
- determining whether or not the first heat source module is operated;
- when the first heat source module is operated, stopping operation of the first heat source module;
- and
- lowering the second heat source module.
