<p>Disclosed is a microwave oven. In the disclosed microwave oven according to the first embodiment having a case forming a cooking chamber, a door for opening/closing said chamber, a high voltage transformer for generating a high voltage, and a magnetron for generating microwaves driven by said high voltage being outputed from said high voltage transformer, microswitches detect an operation of opening/closing of the door, microcomputer produces a driving signal corresponding to the detected result, and relays opens/closes a DC input power source supplied to the high voltage transformer by means of receiving the driving signal. The disclosed microwave oven according to the second embodiment comprises a DC circuit part for converting direct current being supplied by a DC input power source, a magnetron for generating microwaves by using alternating current being produced from the DC circuit part. The connection between the DC input power source and the DC circuit part is controlled by microswitches. Relays are connected to the microswitches in parallel. Then, the holding of the previous status of contacts in microswitches is prevented according as any overcurrent of the current of each microswitch is prevented. Therefore, the operation of the microwave oven is accomplished more safely.</p> |
