電子レンジ。[Claims for Utility Model Registration] Equipped with a commercial AC power source and a DC power source, each power source supplies power to a magnetron that outputs high-frequency energy, and the drive is switched to one of the above two power sources via a contact point. In the AC/DC microwave oven configured as above, an inverter is provided to convert the voltage of the DC power source to a commercial frequency voltage, and the above contact is switched to the state where the microwave oven is driven by the DC power source, and the inverter is connected to the AC power source via the transformer. An AC/DC microwave oven characterized in that the microwave oven is configured to supply voltage to each motor provided on the side, and each motor of the microwave oven is driven by being connected to an AC power source.
