ABSTRACT:
An exhaust structure for ventilation-hooded microwave ovens is disclosed. The exhaust structure includes an exhaust motor mounted to the rear portion of an air duct, an instrument compartment divided into front and rear portions by an air guide plate, an internal exhaust passage formed at the rear portion of the instrument compartment, and a lower panel mounted at the lower portion of the instrument compartment. Electronic equipment, used for generating microwaves, is installed at the front portion of the instrument compartment. The lower panel has exhaust holes communicating with the internal exhaust passage, thus allowing the exhaust passage to be linearly formed on the same plane at a position between the exhaust motor and the lower panel.
