Abstract

Abstract In an automatic cooking of cake, a gas sensor (10) and a weight sensor (9) are used to determine a total heating time. The initial weight of a food item (cake) (17) is measured by the weight sensor (9), and a time (T W ) proportional to a detected value of the weight sensor (9) is determined. The amount (ΔH) of change in humidity level until an arbitrarily chosen timing is detected by the gas sensor (10), and a time (T (ΔH) ) proportional to a detected value of the gas sensor (10) is determined. These times (T W ) and (T (ΔH) ) are added together to determine a total cooking time. With this arrangement, regardless of the kind and amount of cake and the shape of a vessel, the automatic cooking capable of giving a fine finish can be accomplished merely by selecting a single auto-key called a cake key.
