ABSTRACT:
The present invention provides a cooking heater which continues cooking without apparently stopping the operation of the cooking heater when a door switch is momentarily turned OFF due to a shock during operation of the cooking heater though the door is not actually opened as far as continuation of the OFF-state is within a predetermined range. Upon receiving a door opening signal, a timer of control means starts counting and when a first period lapse judgment section judges that the count time exceeds a first period T1, a central control section instructs a heating means control section to stop the operation of heating means. Then, before the count time is judged to exceed a second period T2, when a second period lapse judgment section receives a door closing signal, the central control section restarts the operation of the heating means and continues the operation of the cooking heater.
