Claim:
1. A method for transmitting data from an induction heating device to a receiver of an inductively heatable cooking vessel, the method comprising: utilizing a converter of the induction heating device to generate, from an AC mains voltage, a control voltage having a control frequency, the control frequency comprising a frequency shift keyed amplitude modulated signal; applying the control voltage having the control frequency to a resonant circuit of the induction heating device; in response to applying the control voltage to the resonant circuit, generating an alternating magnetic field for heating the inductively heatable cooking vessel; changing the control frequency of the control voltage in a range of 0.1% to 5% with respect to a base frequency to generate at least two discrete control frequencies for encoding data to be transmitted via the control voltage having the at least two discrete control frequencies to a receiver of the inductively heatable cooking vessel; and transmitting the encoded data via the at least two discrete control frequencies of the control voltage to the receiver of the inductively heatable cooking vessel.
