Abstract: An induction heating cooker for achieving high output of power and small thickness is provided. The induction heating cooker includes a main body provided at an upper side with a top plate, a heating coil to induction-heat a heating object loaded on the top plat, and a blower device configured to draw external air into the main body and blow the air into the heating coil. The heating coil and the blower device are accommodated in the main body. The main body is provided therein with a first flow path allowing air blown by the blowing device to be supplied toward the heating coil from an outer periphery side and a second flow path allowing air blown by the blowing device to be supplied toward the heating coil from a lower side.

Abstract: The present disclosure includes a washing machine including an inner rotor and an outer rotor. An outer rotor and an inner rotor may be rotated in a synchronous rotation mode or a counter rotation mode by converting the number of magnetic poles of the outer rotor. When the outer rotor becomes inoperable when the outer rotor is set to the number of magnetic poles for performing the counter rotation mode, it is converted to the number of magnetic poles for performing the synchronous rotation mode while the outer rotor is stopped.

Abstract: An induction heating apparatus is provided. The induction heating apparatus includes a heating coil, an inverter, a current sensor configured to measure a driving current supplied from the inverter to the heating coil, and a controller configured to provide a drive signal to the inverter to allow the driving current to follow a target current based on a user input. The controller reduces a driving duty of the drive signal based on the driving current exceeding a predetermined reference current, and the controller provides a drive signal to the inverter to allow the driving current to follow a current less than the target current, based on the driving current being less than or equal to the predetermined reference current after reducing the driving duty of the drive signal.
