Abstract:
A heating apparatus for cooking comprising:a heating chamber in which a target food to be cooked is placed and then heated;heating means for irradiating a microwave on the target food;infrared ray (IR) detection means comprising a plurality of detection elements for detecting a plurality of detection areas in the heating chamber by a non-contact manner;temperature calculation means for calculating temperatures of the plurality of detection areas based on the detection results obtained by the IR detection means;heating process control means for controlling a heating process for the target food based on calculation results obtained by the temperature calculation means; anddetection target judgment means for judging a type of each detection area in the heating chamber corresponding to each of the plurality of detection elements based on a detected initial temperature distribution of the heating chamber, wherein the type of the detection area is one of three types, a direct detection area where there is only a part or entire of the target food and the target food is directly detected, a boundary detection area where there are both a part or entire of the target food and a background simultaneously, and a background area where there is no target food,wherein the heating process control means controls the heating process based on the detection results obtained by the detection target judgment means.
