Abstract

PURPOSE:To realize unfreezing of cooked and frozen food without deteriorating the quality of it, and also to realize optimum heating to the food, based on the volume of it, by detecting a needed time until a detected value reaches a specified value corresponding to the frozen state of a food, and by controlling a heating source to high output after continuing the low output state until the detected value reaches a value a little higher than the specified value, when the detected time is shorter than a set time. CONSTITUTION:A heating time 'T1' is the time until the level difference of a sensor level 'Vs reaches a specified value 'Vs1' from the minimum level 'V0'. It corresponds to the volume of a food 7. When the heating time 'T1' is short, the heating state by low output 'P1' is continued until the level difference of a sensor level reaches a value 'Vs2'. When the level difference reaches 'Vs2', a control part 22 controls to change the capacity of a magnetron 4 up to high output 'P2' and heating by it is continued until the level difference of a sensor level reaches 'Vs3', which corresponds to the finish state. In case the food 7 is a large one, it is heated by low output 'P1' for a long time until the level difference 'Vs1' is detected, so that the food is unfrozen completely. The magnetron 4 is immediately changed up to high output 'P2' when the level difference 'Vs1' is detected, and it is continued until the level difference of a sensor level reaches 'Vs4' that corresponds to the finish state, or until the high output heating time being determined by the heating time 'T1' which corresponds to the volume of a food 7 elapses.
