Title:
COOKING APPARATUS
Document Type and Number:
WIPO Patent Application WO/2011/149275
Kind Code:
A2
Abstract:
Provided herein are a cooking apparatus and an operating method thereof. The cooking apparatus includes a microwave generator to generate and output microwaves of a plurality of frequencies to heat an object within a cavity, a resonance mode conversion unit to convert a resonance mode by varying at least one of progressing direction, power or frequency of the microwaves output to the inside of the cavity, and a controller to operate the resonance mode conversion unit, if the number of frequencies of microwaves, the heating efficiencies of which are more than a reference heating efficiency, is below a reference value, based on heating efficiencies calculated according to microwaves reflected by the inside of the cavity from among the output microwaves. Thereby, operating efficiency of the cooking apparatus is improved.
