HEATING DEVICE

摘要

A heating device in which irrespective of the material and temperature characteristics of a heating body heated by electromagnetic induction, abnormally high temperature detecting means and temperature operating means can be quickly and infallibly operated through an inexpensive, compact structure when the temperature of the heating body becomes abnormally high. A thermostat (301) is disposed between bundles of conductors of exciting coils on the same side as exciting coils (231) with respect to a heating belt (210). Therefore, the thermostat (301) and the exciting coils (231) can be held together by a coil guide (234), and their wirings and terminals are disposed concentratedly at one portion. Therefore, the number of parts and the number of assembling steps can be decreased and the device body can be compactly structured at lower cost. Further, irrespective of whether or not the material of the heating belt (210) is magnetic and whether or not the temperature of the heating belt (210) is above the Cuie point, the thermostat (301) correctly operates if the heating belt (210) is heated to an abnormally high temperature.
