Method For Operating An Induction Hob On Which A Ferromagnetic Element Is Placed
Patent No. EP4021144 (titled "Method For Operating An Induction Hob On Which A Ferromagnetic Element Is Placed") was filed by Groupe Brandt on Dec 20, 2021. The application was issued on Jul 24, 2024.
Patent Summary
An induction hob operating method utilizes at least two inductors to identify a set of adjacent inductors partially or fully covered by a ferromagnetic element. To prevent heating small non-container elements (e.g., cutlery) while ensuring uniform container heating, the method employs a secondary comparison step. A parameter ($P_v$), derived from physical quantities (e.g., voltage, current, power, or switching parameters) measured as values ($V_{mi}$) for each inductor in the set, is compared against a secondary threshold ($V_{ss}$). If the result is positive, all inductors in the assembly are activated. Optionally, this secondary comparison is triggered only if the number of identified inductors is below a predefined threshold, utilizing a control unit with a mapping of inductor positions, sizes, and shapes.
