MICROWAVE OVEN HAVING OVERCURRENT CIRCUIT BREAKER APPARATUS

摘要

PURPOSE: A microwave oven having an overcurrent circuit breaker is provided to repair the microwave oven easily when the microwave oven is out of order. CONSTITUTION: The microwave oven(1) has a power inlet apparatus for incoming the source power, a power circuit breaker(42) for breaking the power, and the primary microswitch(22) for supplying the incoming source current to the high voltage transformer(HVT). The primary microswitch is opened and closed according to the opening and the shutting of a door. If the door is opened and the primary microswitch is closed, then the circuit breaker automatically isolates the input power from the microwave oven.
