Abstract
A wall mounted microwave oven is provided which includes a body forming therein a cavity for accommodating food to be cooked, a magnetron for generating electromagnetic waves to be provided into the cavity, a casing surrounding the body and forming therein a hood duct having an inlet port positioned at the bottom portion of the casing and an outlet port positioned in the upper portion thereof, and a hood fan installed in the hood duct. The wall mounted microwave oven includes a hood sensor for sensing a status that operation of saidhood fan is needed; a first switch for selectively supplying one out of a low-level voltage and a normal voltage to the magnetron, and a controller for controlling the hood fan to operate if a detect signal informing operation of said hood fan is needed is input from the hood sensor and simultaneously controlling the first switch to change the electric power to be supplied to the magnetron from the normal voltage into the low-level voltage. Accordingly, the microwave oven can control operation of a hood fan based on a detect signal sensed by a hood sensor and simultaneously lower an electric power voltage level to be supplied to a magnetron, thereby effectively preventing an overload from being applied to the microwave oven.
