Disclosed is an AC/DC type microwave oven. The disclosed AC/DC type microwave oven comprises: a selecting switch for selecting an AC input power or a DC input power; a supplier for supplying power using a common driving load being driven by the DC power, and supplying the AC input power or a DC/AC converted power selected by the selecting switch; and a microwave oscillator being driven by the AC power supplied by the supplier. The AC/DC type microwave oven comprises: a rectifier for rectifying the AC input power into a DC power; a driving load being driven by the rectified DC power or the DC input power; a rotatable inverter including a motor being driven by the DC input power, and a commutator for producing AC power according as the DC input power being inputted to one direction which is outputting in turn in two directions by means of input/output brushes being contacted with four directions of the commutator and being rotated by a motor; and microwave oscillating part for being driven by the AC power converted by the rotatable inverter or the AC input power. According to the present invention, since the AC/DC type microwave oven adopts only DC driving load driven by the DC power, the manufacturing cost is reduced due to the reduced number of parts of the AC driving load. Besides, this microwave oven is prevented from the faulty operation by means of selecting only one of the AC power or the DC power available. |
