摘要： PURPOSE:To eliminate unevenness in heating and enable automatic cooking by setting the antenna drive position by reference to the microwave power to be transmitted in a waveguide pipe in different rotational position of each matching antenna measured and stored previously, and by controlling the programming for the heating times. CONSTITUTION:Matching antennas 10 ate rotated, and the microwave power from a magnetron 5 transmitted in a waveguide pipe 5 through a directional coupler 6 in a plurality of rotational positions is measured and stored, and by reference thereto a control device 19 sets the drive position of the antennas 10 for uniform heating of the food placed. Further the control device 19 stops antenna 10 at every set position and controls a heating time setting means 18 so that the heating energy becomes uniform in accordance with the reflection/ incidence values of microwave power based upon the stored measurements. According to this constitution in which the standing wave distribution in the heating chamber is varied, automatic cooking is established in which the unevenness in heating can be precluded, discrimination between frozen food and normal temp. food be done, and the heating conditions be set automatically.
