ABSTRACT:
A first portion of a top plate section of an induction heating cooking apparatus is used for placing a cooking pan thereon. A second portion of the same is used for controlling an output of an oscillation circuit for induction-heating the pan. The output control device includes a permanent magnet movably disposed along a groove provided in the surface of the second portion of the top plate section, a magnetic field adjusting plate provided on the inner surface of the second portion corresponding to the groove, a magnetic field detecting circuit including a Hall element provided close to one end of the magnetic field adjusting plate, and an oscillation output control circuit for controlling the output from the oscillation circuit by a control signal obtained by comparing the output signal from the magnetic field detecting circuit with a reference signal.
