Claim 0:
1. A wireless induction heating cooker, wherein the wireless induction heating cooker is configured to operate on an induction heating apparatus including a heating coil, the wireless induction heating cooker comprising:
a main body having an upper surface defining an opening;
a lid configured to be coupled to the upper surface of the main body;
an internal pot received in the main body and configured to be heated using a first magnetic field generated in the heating coil of the induction heating apparatus;
a first power receiving coil placed on an inner bottom surface of the main body, wherein electric currents are induced by the first magnetic field generated in the heating coil;
a lateral surface heating coil placed on an outer circumferential surface of the internal pot and, the lateral surface heating coil being connected with the first power receiving coil and configured to heat the internal pot using the electric currents provided by the first power receiving coil;
a power transmitting coil disposed on a lateral surface of the main body and configured to receive the electric currents induced to the first power receiving coil and generate a second magnetic field; and
a second power receiving coil disposed on a lateral surface of the lid and that configured to supply electric currents to one or more electronic devices, the electric currents being induced by the second magnetic field generated in the power transmitting coil,
wherein a first end of the first power receiving coil and a first end of the lateral surface heating coil are directly connected to each other, and a second end of the first power receiving coil and a second end of the lateral surface heating coil are connected to a resonance capacitor,
wherein the first power receiving coil is horizontally placed below an edge area of the internal pot, and
wherein the edge area is defined between an outer diameter of the internal pot and a second reference radius that is larger than the outer diameter of the internal pot.
