摘要： The present invention relates to a method for controlling a cooking process by using a liquid in a cooking vessel, for example a cooking pot, upon a cooking hob (20). The method comprises a step of determining a cooking parameter of the liquid in the cooking vessel at a predetermined time (tB, tBP), a step of adjusting a heating power density (P) of a cooking zone of the cooking hob (20) for transferring a heating power (P) to the cooking vessel placed on the cooking zone; and a step of reducing the heating power density (P) transferred to the cooking vessel from an initial power (iP) to a simmering power (PS). Further, the present invention relates to a cooking vessel for the cooking hob (20). Moreover, the present invention relates to a cooking appliance for performing the cooking process.

摘要： The present invention relates to an induction cooking hob (10) with an integrated down-draft hood. The down-draft hood includes at least one downstream channel (40) extending from an air inlet (18) to an air outlet (36). The air inlet (18) is arranged within and/or beside a cooking panel (12) of the induction cooking hob (10). The air outlet (36) is arranged in a bottom wall and/or side wall of a chassis of the induction cooking hob (10). At least one heat sink (28) is arranged in and/or at the down-stream channel (40). The heat sink (28) is thermally connected to at least one power circuit for at least one induction generator. The heat sink (28) provides a heat exchange between the power circuit and an air stream through the downstream channel (40), so that the power circuit is cooled down.

摘要： An induction hob including a first heating region with a first induction coil and a second heating region with a second induction coil is provided. First and second resonant converters drive an AC current through the first and second induction coils. The first and second resonant converters form a half-bridge resonant converter that is continuously driven such that a direction of current flow through the first induction coil and the second induction coil is alternating. The half-bridge resonant converter controls the output power of the first and second heating regions by varying the frequency of the AC current through the respective induction coil. The first and second resonant converters have different resonance frequencies such that the resonance frequency of the first resonant converter is at least 1.4 times higher than the resonance frequency of the second resonant converter.
