ABSTRACT:
A wall mounted-type microwave oven provided with a hood having an inlet port with an improved structure, thus effectively drawing exhaust gases and food odors produced from a plurality of gas burners placed below the hood. The wall mounted-type microwave oven includes a cabinet and a hood. The cabinet has, at predetermined portions thereof, an exhaust passage and an exhaust fan. The hood is mounted to a bottom portion of the cabinet, and has an inlet port to communicate with the exhaust passage. The inlet port is formed so that a width of an end of the inlet port near to the exhaust passage is less than a width of an end of the inlet port farther from the exhaust passage. Thus, the inlet port is formed so that an area of a portion of the inlet port on which a weaker suction force of the exhaust fan acts is larger than an area of a portion of the inlet port on which a stronger suction force of the exhaust fan acts.
