AC/DC MICROWAVE OVEN HAVING FUNCTION FOR DISPLAYING BATTERY RESIDUAL QUANTITY

摘要

PURPOSE: AC/DC microwave oven has a function which displays a battery residual quantity. CONSTITUTION: AC/DC microwave oven includes a converter(100), a high voltage transformer(200), and a magnetron(MGT). The microwave oven includes a voltage detector(330) for detecting an output voltage of the battery. A microcomputer senses a battery residual quantity by sensing an output voltage of the voltage detector, and outputs a corresponding control signal. Alarm/display part(320) displays a battery residual quantity or alarms it according to the control signal of the microcomputer. Thereby, the user can recognize a battery state, the microwave oven alarms a dangerous battery state to the outside, and stops its operation.
