Abstract (en)
[origin: EP3836752A1] This invention discloses a method for cookware placement (3) on an induction cooktop surface (10) using the temperature control loop (15). The method uses readings from the thermal sensor (11), and another sensors, e. g., 1-, 2- or 3-axis-accelerometer (12), microphone and/or wire loop (13), with modulating the heating power to induction coils and measuring respective signals in the cookware (3) for its placement identification. The alternating magnetic field vibrates the magnetic base of cookware (3) thus providing a signal to the accelerometer. The wire loop (13) senses and measures strength of alternating magnetic field having a priori known frequency, states relevant to the heating power On or Off states and also the modulation states of the heating power signal. Therefore, said vibrations, the measured magnetic and/or electric field strength and their modulations assist at least for identification of cookware placement, i.e., which cookware item is on which heating area and if placed correctly.
