Claims

[Scope of utility model registration request]

When a momentary power outage occurs in a microwave oven equipped with a detection element such as a gas sensor and a microprocessor, the current supply to the display drive circuit, motor drive circuit, sensor heater circuit, etc. is stopped if it is instantaneous. A microwave oven characterized in that it is provided with a control means for cutting off current to a circuit that does not cause any hindrance.
