COOKING VESSEL DETECTION APPARATUS, COOKING VESSEL DETECTION METHOD, AND INDUCTION HEATING COOKER

An induction heating cooker comprises a rectifying unit for rectifying an AC voltage from a power supply to a DC voltage and first and second switching units for switching to alternately apply the DC voltage from the rectifying unit to the working coil for driving the working coil.A device of sensing a cooking container in the induction heating cooker comprises a first current sensing unit configured to sense a first current flowing between the power supply and the rectifying unit, a second current sensing unit configured to sense a second current flowing to the working coil, and a controller configured to determine if the cooking container placed on the working coil is present based on the first and second currents.
