The induction heating device

The present invention relates to an induction heating device, in order to make a high electrical conductivity such as aluminum and having a low magnetic permeability material to be heated buoyancy reduction was applied, the conductive member is provided between the heating coil and the object to be heated, in order to increase equivalent series resistance heating coils. Thus, to obtain the desired current required heating output of the heating coil is reduced, the buoyancy can be reduced to be heated. Further, the conductive material is divided into two and disposed in an arc shape with a gap, through intimate contact with the lower surface of the tray, the conductor temperature rise can be suppressed. Further, the heat conductive member is transferred to the object to be heated and the heat, even if the conductive heating body, the heating coil is not damaged and the like. The conductor is provided with a temperature sensor detecting the temperature of the conductor, when the detected temperature is above a predetermined temperature, by reducing the heating output of the drive circuit, can reduce heat conductor, it is not subjected to the heating coil or the like due to heat damage.
