ABSTRACT:
A wall-mounted type microwave oven selectively changes a discharging direction of air from a cooking chamber to the outside of a room and to the inside of the room. The microwave oven includes an oven body having a cooking chamber and an electric component compartment, an exhaust flow path which communicates with a lower portion of the oven body and an upper portion of the oven body to exhaust air existing under the oven body to the outside, a ventilation flow path which communicates with the inside of the cooking chamber and a front air outlet to ventilate the cooking chamber, a communicating flow path which is provided in the oven body and allows the exhaust flow path to communicate with the ventilation flow path, and a path-converting device which is provided in the communicating flow path and selectively discharges the air exhausted from the cooking chamber toward either the front air outlet or the exhaust flow path.
