Abstract
A wireless induction heating system includes an induction heating device having a heating coil configured to generate a magnetic field and a wireless induction heating cooker disposed in an area formed by the heating coil and configured to perform cooking operation based on the magnetic field generated by the heating coil. The induction heating device and the wireless induction heating cooker can perform mutual data communication to control output of the heating coil and output abnormality information, based on a displacement state of the wireless induction heating cooker with respect to the induction heating device.
Claims20
A wireless induction heating system, comprising:
- an induction heating device including a heating coil defining a heating area and configured to generate a magnetic field;
- and
- a wireless induction heating cooker configured to be positioned on the heating area of the induction heating device, and configured to perform a cooking operation using the magnetic field generated by the heating coil,
- wherein the induction heating device and the wireless induction heating cooker are configured to perform data communication with each other and control output of the heating coil based on a position of the wireless induction heating cooker relative to the induction heating device, and
- wherein the induction heating device and the wireless induction heating cooker are configured to output abnormality information based on the position of the wireless induction heating cooker being an abnormal position.
A wireless induction heating cooker, the wireless induction heating cooker configured to operate on an induction heating device having a heating coil, the wireless induction heating cooker comprising:
- a main body having an upper surface defining an opening;
- a lid configured to cover the upper surface of the main body and including a plurality of electronic devices;
- an inner pot received in the main body and heated using a first magnetic field generated by the heating coil of the induction heating device;
- a first power receiving coil disposed on a bottom surface of the main body, wherein current is induced in the first power receiving coil based on the first magnetic field generated by the heating coil;
- a side heating coil disposed around an outer side surface of the inner pot, the side heating coil being connected to the first power receiving coil and configured to heat the inner pot based on the current induced in the first power receiving coil;
- a power transmitting coil disposed at a side of the main body and configured to receive the current induced in the first power receiving coil and generate a second magnetic field;
- a second power receiving coil disposed at a side of the lid and configured to supply a current to one or more of the plurality of electronic devices, the current being induced by the second magnetic field generated by the power transmitting coil;
- a controller configured to determine an displacement state of the wireless induction heating cooker relative to the induction heating device based on a change in an amount of current through at least one of the first power receiving coil and the second power receiving coil;
- and
- a communicator configured to perform data communication with the induction heating device based on the displacement state of the wireless induction heating cooker.
