Wireless induction heating cooker and wireless induction heating system including same

A wireless induction heating cooker configured to operate on an induction heating apparatus, the wireless induction heating cooker comprising:

• a main body having an upper surface that defines an opening;
• a lid that is configured to rotate relative to the main body to thereby couple to the upper surface of the main body;
• an internal pot that is configured to be received in the main body and that is configured to be heated by induction based on a first magnetic field being generated by a heating coil of the induction heating apparatus;
• a first power receiving coil disposed at a bottom surface of the main body and configured to generate a first electric current based on induction by the first magnetic field;
• a power transmitting coil disposed at a lateral surface of the main body and configured to receive the first electric current induced to the first power receiving coil, the power transmitting coil being configured to generate a second magnetic field based on receiving the first electric current;
• a second power receiving coil disposed at a lateral surface of the lid and configured to generate a second electric current based on induction by the second magnetic field;
• and
• a control module that is configured to determine a coupling state between the lid and the main body based on an amount of the second electric current induced to the second power receiving coil.
