Abstract
A heating apparatus that enables an abnormally high temperature detection section that detects, when a heating element heated by means of electromagnetic induction reaches an abnormally high temperature, this abnormally high temperature, to operate speedily and reliably irrespective of the material and temperature characteristic of the heating element in a low-cost and compact configuration. In this apparatus, thermostatis disposed on the same side as exciting coilwith respect to heat generating beltand between winding bundles of a conductor wire of exciting coil. This allows coil guideto hold both thermostatand exciting coiland allows these wires and terminals to be concentrated on one location, thus making it possible to reduce the number of parts and assembling man-hours and configure the body of the apparatus in a low-cost and compact configuration. Furthermore, thermostatoperates reliably when heat generating beltreaches an abnormally high temperature irrespective of whether the material of heat generating beltis a magnetic member or not and whether the temperature of heat generating belthas exceeded a Curie temperature or not.
