Abstract
An electromagnetic induction device including a wireless power transmission unit including an induction coil configured to generate a magnetic flux in an up-down direction to heat an external device located above the indication coil by induction heating, and a communication unit including a communication coil configured to output a carrier wave, and a relay circuit configured to resonate at a frequency of the carrier wave, to wirelessly communicate with the external device.
Claims15
An electromagnetic induction device comprising:
- a wireless power transmission unit including an induction coil configured to generate a magnetic flux in an up-down direction to heat an external device located above the induction coil by induction heating;
- and
- a communication unit including a communication coil configured to output a carrier wave, and a relay circuit configured to resonate at a frequency of the carrier wave, to wirelessly communicate with the external device.
A method of operating an electromagnetic induction device, the electromagnetic induction device including a wireless power transmission unit that includes an induction coil configured to generate a magnetic flux in an up-down direction, and a communication unit that includes a communication coil configured to output a carrier wave, and a relay circuit configured to resonate at a frequency of the carrier wave, the method comprising:
- driving the induction coil to generate the magnetic flux so that an external device located above the induction coil is heated by induction heating;
- and
- driving the communication coil to output the carrier wave, and resonating the relay circuit at the frequency of the carrier wave, to wireless communicate with the external device.
