Abstract
The present invention relates to a microwave oven including a cavity having a certain area for cooking comprising a flow path formed between a main body and the cavity so as to be connected from a side of the cavity to the upper surface of the cavity, a heater installed on the side of the flow path corresponding to the outer upper surface of the cavity for emitting heat, a discharge hole installed on the upper surface of the cavity corresponding to the lower portion of the heater for discharging the heat of the heater into the cavity, an inlet installed on the lower portion of the side wall of the cavity for making the air inside of the cavity flow in the flow channel, and a circulating fan installed on a certain portion of the flow channel for circulating the air inside of the cavity flown through the inlet to the heater. Accordingly, the microwave oven of the present invention is capable of maximizing the heat exchange efficiency between the heater and air, increasing the heat efficiency, and heightening the cooking quality and cooking speed by improving the heat transmission structure of the heater providing the heat to the cavity.
