Abstract
The present invention relates to a microwave oven including a cavity having a certain area for cooking, a magnetron installed at the outside of the cavity for generating microwave, a waveguide installed at the side of the magnetron and its end extended inside of the cavity for transmitting the microwave inside of the cavity. The microwave oven comprises a bidirectional flow channel formed inside of the waveguide for transmitting microwave selectively inside of the cavity in accordance with cooking function, a microwave plate combined to inside of the waveguide so as to be rotational for guiding the microwave to selected direction between the two direction of the flow channel, and a plasma lamp installed adjacent to the side of the bidirectional flow channel for generating radiant energy by being heated by the microwave. Accordingly the microwave oven of the present invention is capable of efficient cooking by including both convection cooking and grill cooking functions, and speed cooking by convection-performing the radiant energy of the plasma lamp.
