Abstract:
A microwave heating apparatus comprising:a heating cavity for housing an object to be heated;a tray provided inside of said heating cavity for supporting the object to be heated;a magnetron for irradiating microwaves;a wave guide for guiding the microwaves, irradiated by said magnetron, into said heating cavity,said wave guide having an opening communicating with said heating cavity for feeding the microwaves traveling through said wave guide into said heating cavity from a side thereof;at least one metal plate rotatably disposed in said wave guide for influencing the direction of the microwaves depending upon the rotational position of said metal plate; anddriving means for rotating said metal plate;a sensor for detecting physical properties of the object to be heated, wherein the angle of said metal plate with respect to a bottom surface of said wave guide is variable according to detection results obtained from said sensor.
