Patent ID: 8525086

Claim:
A microwave heating appliance, comprising: a microwave generating unit; a waveguide which transmits a microwave from the microwave generating unit; a heating chamber which houses a heated subject that is heated by the microwave; a rotating antenna which radiates the microwave from the waveguide to the heating chamber; a driving unit which rotates and drives the rotating antenna; a temperature distribution detecting unit which detects a temperature distribution in the heating chamber; and a controlling unit which controls a direction of the rotating antenna by controlling the driving unit based on a detected result of the temperature distribution detecting unit, wherein the controlling unit controls a sharp part of radiation directivity of the rotating antenna in a direction decided based on the detected result of the temperature distribution detecting unit to execute a concentrated heating, wherein the controlling unit includes an antenna angle storing portion which stores an angle of the rotating antenna when the sharp part of the radiation directivity of the rotating antenna is directed to a particular area in the heating chamber, and wherein the controlling unit directs the sharp part of the radiation directivity of the rotating antenna toward a low temperature portion of detected areas detected by the temperature distribution detecting unit.
