Induction heating device i.e. household induction hob, has induction heating units connected with respective frequency units, and control unit determining typical switching frequency of frequency units depending on characteristic of sensor

摘要

The device (12) has two heating frequency units (30, 32) connected together over two sets of induction heating units (20-26) in an operating mode, where one of the sets of induction heating units is directly connected with one of the heating frequency units, and the other set of the induction heating units is directly connected with the other heating frequency unit in the operating mode. A control unit (34) determines typical switching frequency of the heating frequency units depending on a characteristic of a sensor i.e. ammeter.
