Abstract
In a sake/milk heating process, the field of view of an infrared sensor is moved by a predetermined pattern in a heating chamber as an initial search. When the field of view is fixed after the initial search, if the temperature variation of an object within the field of view after a predetermined time has passed is equal to or lower than a specified value, various determinations are made, and the field of view of the infrared sensor is again moved in the heating chamber as a re-search. Thus, even if the field of view is fixed at a position where no food item is placed for some reason in the initial search, the field of view will not be fixed in the incorrect position and can be moved again.
