Abstract
A microwave oven includes radiation detecting means for detecting radiations from at least two detection points within a heating oven of the microwave oven. A signal of the radiation detecting means derived from that point of said at least two detection points which is at relatively high temperature is used to control a high frequency wave generator which feeds a high frequency wave into the heating cavity. The radiation detecting means includes a radiation detector and a chopper which chops radiations directed to the radiation detector from said at least two detecting points.
Claims11
A microwave oven comprising a heating cavity in an oven body, a high frequency wave generator for feeding high frequency waves into said heating cavity, radiation detecting means for sequentially detecting radiations from at least two points within said heating cavity, and control means for controlling said high frequency wave generator by signal from said radiation detecting means, said control means controlling said high frequency wave generator by a signal from that one of said two points which is at relatively higher temperature.
A microwave oven comprising a heating oven in an oven body, a high frequency generator for feeding a high frequency wave into said heating cavity, radiation detecting means for detecting radiations from at least two points within said heating cavity, control means for controlling said high frequency generator by a signal from said radiation detecting means, and a turn table for rotating an article to be heated placed in said heating cavity, said radiation detecting means detecting the temperature while it is scanned radially of the turn table.
