ABSTRACT:
A microwave dispersing apparatus of a microwave oven having a dispersing unit for evenly dispersing into a cooking chamber through first and second waveguides the microwaves generated by oscillation of a magnetron, the apparatus comprising: a rotary motor mounted on a first waveguide; first and second pulleys installed at the first and second waveguides for being rotated along with a driving rotary motor; a belt positioned between the first and second pulleys for enabling the two pulleys to be simultaneously rotated; first and second feeders disposed for being subsequently rotated by the rotating first and second pulleys; and first and second rotary antennas rotatively installed for evenly dispersing microwaves to the cooking chamber through the first and second waveguides as the antennas are eccentrically rotated by the power of the first and second feeders.
