PURPOSE:To increase reliability for the heating cooker by a method wherein the output of a volume is prevented under setting from being impressed by noise and quivering the indication of the setting in the heating cooker of a system in which heating time and heating temperature are set by the volume. CONSTITUTION:The volumes 2, 3, for setting the heating time and heating temperature, and a fluorescent indicating tube 4, reading the output values of the volumes, are provided to indicate at first when the coinciding number of times of the output values of the volumes exceed a constant number of times while the constant number of times is set at different values during operation and non- operation and the number during non-operation is set at larger number. According to this method, the change of indication, which is changed due to the impression of noise on the output of the volume during setting even without turning the volume, may be prevented. Further, the operability of the cooker will never be spoiled even during turning the volume to set actually the heating time and temperature. Furthermore, a chance in which an user thinks that a microcomputer has caused a malfunction may be eliminated and the reliability may be improved. |
