Abstract
A microwave oven includes a hood unit including a hood motor, a magnetron, a transformer having primary and secondary coils, the transformer generating a high voltage in a turn ratio of the primary and secondary coils and supplying the generated high voltage to the magnetron, a hood unit driver for controlling an operation of the hood unit, power output switching means for controlling the level of a voltage to be supplied to the transformer, and a controller for controlling the power output switching means to control the level of the voltage to be supplied to the transformer according to a given operation mode of the hood unit. The power output level of the microwave oven is automatically controlled according to a given operation mode of the hood motor such that the sum of the oven power output and the hood motor power output is constant.
