Abstract

A non-directional frequency generator inputs direct current power and outputs alternating current power. A high voltage transformer inputs the alternating current power, and either induces a higher voltage for driving the magnetron, or induces and outputs a commonly used alternating current power. A button inputting section includes a microwave oven operating button for driving the magnetron, and a voltage supplying button for supplying the commonly used alternating current power. A microcomputer applies the higher voltage of the high voltage transformer to the magnetron when there is a button input through the microwave oven operating button, while outputting the commonly used alternating current power when there is a button input through the voltage supplying button. Further, a socket outlet is formed on the body of the microwave oven, through which the commonly used alternating power generated at the microwave oven is supplied. Accordingly, since the commonly used alternating current power is supplied from an AC/DC type microwave oven, a user can use AC type electric appliances in places where alternating current is unavailable.
