Abstract

The present invention relates to a power control device of an induction heating cooker, and in the related art, the upper surface of the mounting part is marked with an oval container placing position, and a working coil for heating the container is wound thereon in proportion to the container placing position indication. When induction heating is performed by applying a high frequency current to the working coil, there is a problem in that unnecessary power loss occurs when heating at the same power when the container is small or when the container is misplaced. Therefore, the present invention indicates a position where a plurality of small containers can be placed in the container display portion indicated by one oval on the upper surface of the mounting portion, and under the marked position, a plurality of working coils wound by a small number of turns are used. By only operating the working coil in the position where the container is placed to perform cooking to prevent power loss at the optimum power.
