Abstract
A high-frequency heating apparatus capable of simultaneously heating different kinds of objects to appropriate temperatures includes: a power feed portion provided on a right side wall forming a heating chamber; a mounting table on which to mount objects to be heated; a rotating support of an improved structure; a drive motor; a temperature detection means having an area in front of the power feed portion as a detection area; and a control means; wherein high-frequency radiation variations are formed by the power feed portion and the rotating support and, based on a signal from the temperature detection means, the control means identifies positions of the objects on the mounting table and controls the drive motor to move the lower-temperature object to where a high-frequency radiation is strong to eliminate insufficient heating of the object and to simultaneously heat a plurality of objects to appropriate temperatures.
