ABSTRACT:
A wall mounted type microwave oven having an external enclosure including a bottom closure wall which includes a suction opening and a top vent opening and an oven cavity which is supported within the external enclosure. The oven cavity has a rearwardly stepped portion to maximize the usable space provided within the oven cavity. An air exhaust air path is formed between the external enclosure and the oven cavity and includes a bottom plenum, a pair of rear air channels and an upper plenum. The rearwardly stepped area divides the space between the oven cavity and the external enclosure into the two rear air channels. At least one blower is provided within the external enclosure for drawing air into the bottom plenum through the suction opening and exhausting the air out through a top exhaust opening which forms part of the top vent opening. By providing the air exhaust path along the bottom plenum, the two rear air channels and the upper plenum and by having the air exhaust path not occupy any space along the sides of the oven cavity, a maximum oven cavity width is achieved. By directing the exhaust air stream through the two rear air channels maximizes at the same time the usable space within the oven cavity.
