Abstract:
A microwave oven comprising:a heating chamber for holding food; a microwave source to heat said food; a temperature detector detecting temperatures at a plurality of locations in said heating chamber; a controller controlling heating operations of said microwave source based on detection output from said temperature detector; said controller including a first evaluation module; said first evaluation module including means for evaluating whether a maximum temperature in said heating chamber detected by said temperature detector has reached a predetermined temperature when said microwave source is performing said heating operation; a second evaluation module; said second evaluation module including means which, if said first evaluation module determines that said maximum temperature in said heating chamber has reached said predetermined temperature, determines whether there is a particular position, other than said position that reached said predetermined temperature, in said heating chamber that has reached at least a predetermined temperature lower than said predetermined temperature; a heating operation stopping module; and said heating operation stopping module including means, effective if said second evaluation module determines that there is said particular position, for stopping said heating operation of said microwave source when a temperature of said particular position reaches said predetermined temperature.
