Abstract
A microwave heating device includes a waveguide, a metal plate, a magnetron, a heat generating plate, a thermal insulation member and an adjusting member. The waveguide has a waveguide space, in which a sidewall of the waveguide has an opening communicating the waveguide space. The metal plate covers the opening to seal the waveguide space. The magnetron is configured to generate microwaves, in which an output end of the magnetron protrudes into the waveguide space. The heat generating plate is disposed in the waveguide space and is contacted with the metal plate, in which the heat generating plate is configured to absorb microwaves. The thermal insulation member is partially covers the heat generating plate. The adjusting member is disposed in the waveguide space and is located under the heat generating plate.
