Abstract
An induction heating cooker includes a plurality of heating coil blocks including one or more heating coils, a plurality of inverters to supply a high-frequency voltage to each of the heating coils, and a controller to control operations of the plurality of inverters to alternately supply the high-frequency voltage to each heating coil block and detect a heating coil, on which a container is placed, from among the heating coils belonging to each of the plurality of heating coil blocks. Using this configuration, it is possible to reduce the influence of magnetic field interference between adjacent heating coils when detecting the position of the container and to increase container position detection accuracy.
