Abstract
A wall-mounted microwave oven and a method for controlling the same, wherein the microwave oven and a hood unit are prevented from being operated at maximum power at the same time in the initial operation state. The microwave oven comprises 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 a transformer, and a controller for controlling the hood unit driver and power output switching means to prevent the hood unit and a magnetron from being operated at the maximum power at the same time in the initial operation state. In the initial operation state, the hood motor and microwave oven are prevented from being operated at the maximum power at the same time for a certain period of time. Then, the hood motor and microwave oven are normally operated at the maximum power after the lapse of the certain time period. Therefore, the microwave oven can be controlled in entire power consumption and prevented from being overloaded.
