Provided herein are a cooking apparatus. The cooking apparatus includes a cavity, and a microwave generator to generate and output microwaves of a plurality of frequencies to heat an object within the cavity, wherein the microwave generator includes a controller to calculate heating efficiencies based on microwaves reflected by the inside of the cavity from among the output microwaves and to calculate heating modes consisting of microwaves for heating, during a scanning session and to control the heating modes so as to achieve the equal heating time during a heating session. Thereby, the object within the cavity is uniformly heated.

Cooking apparatus and operating method thereof

Provided herein is a cooking apparatus. The cooking apparatus includes a plate forming a cavity, a microwave transmission line to transmit microwaves to the inside of the cavity, and a first metal part connected to one end of the microwave transmission line and extended in one direction so as to be parallel with the plate. Thereby, an antenna having improved efficiency is provided.

Cooking apparatus

A cooking apparatus using microwaves may include a microwave generator that generates and outputs a plurality of microwaves to heat an object in a cavity, and a controller that calculates heating efficiency of each of the plurality of microwaves based on the microwaves reflected from the cavity, and then sets heating time of each of the microwaves during a heating period of time according to the calculated heating efficiency.
