Abstract
The present disclosure relates to an induction heating device. A loaded-object sensor according to the present disclosure is arranged concentrically and centrally in the working coil. Thus, the sensing coil and the working coil are adjacent to each other. When a current for the heating operation is applied to the working coil, an induction voltage is generated in the sensing coil by magnetic force generated by the current applied to the working coil. According to the present disclosure, a resistor circuit is used to reduce the induction voltage generated in the sensing coil when the heating operation of the working coil is performed.
