An induction heating apparatus is provided. The induction heating apparatus includes a heating coil configured to heat an object to be heated, a full-bridge type inverter configured to supply power to the heating coil, a capacitor provided between an intermediate node of one arm of the inverter and one end of the heating coil, and a first relay provided between the intermediate node and the other end of the heating coil. An intermediate node of the other arm of the inverter and an intermediate point of the heating coil are connected through a first wire. The induction heating apparatus includes a processor configured to open or close the first relay based on an impedance of the object to be heated.

Induction heating apparatus

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.

Induction heating cooker

An induction heating apparatus including an inverter comprising a switching element, the inverter configured to supply a power to a first node based on an operation of the switching element; a first heating coil around which a wire is wound in a first winding direction with respect to the first node and configured to be heated by the power supplied from the first node; a second heating coil around which a wire is wound in a second winding direction different from the first winding direction with respect to the first node and configured to be heated by the power supplied from the first node; and at least one processor configured to control a resonance frequency of a current flowing through the first heating coil and the second heating coil.

Provided is a washing machine motor capable of efficiently generating torque by improving a winding factor of coils with a relatively simple configuration. The washing machine motor () has an outer rotor (), an inner rotor (), and a stator (). The outer rotor () and the inner rotor () share coils () of the stator (), and a composite current is supplied to the coils () such that the outer rotor () and the inner rotor () are independently driven. The outer rotor () has forty eight outer magnets () arranged such that the N and S poles thereof are continuously and alternately aligned in the circumferential direction thereof. The inner rotor () has forty-two inner magnets () arranged such that the N and S poles thereof are continuously and alternately aligned in the circumferential direction thereof. The stator () has thirty-six I-shaped cores () and the coils ().
