Abstract

PURPOSE: To improve the safety, by causing a reset terminal of a microcomputer to be actuated by the drop of circuit voltage due to momentary power failure when a heating cooker with a circuit change-over apparatus and a microcomputer is being used.
CONSTITUTION: When during momentary power failure the electric potential on the emitter side of a transistor Q16 that will be determined by the ratio of resistance R14 to resistance R25 has become about 10.6V or less, the Q16 becomes on, and the reset terminal 7 becomes 10V that is in turn detected by the microcomputer 8, so that when the electric power is applied, the heaters 9, 10 can start. When the power has been momentarily failured during the operation of the circuit change-over apparatus 11, an electric potential at A drops suddenly, and when the change-over apparatus 11 stops its operation, an electric potential at B drops to turn the Q1 on, and the reset terminal becomes 10V that is in turn detected by the microcomputer so that when the electric power is applied again, the heaters 9, 10 can start. Thus, even momentary power failure has happened, the safety can be improved without abnormally operating the heating cooker.
