Abstract: In a method for a cooktop, in particular for producing and/or operating the cooktop, which has at least one variable cooking surface, the cooking surface is partitioned in an operating mode along a partitioning direction into a plurality of heating zones to which at least one heating parameter is assigned in each case in a location-dependent manner in order to heat a cooking utensil that is deposited on the heating zone. In order to ensure flexible production and/or flexible operation of the cooktop, during partitioning of the cooking surface into the heating zones in at least one peripheral region of the cooking surface, at least one cooking utensil characteristic is taken into account.

Abstract: A cooktop apparatus includes a first heating frequency unit, a second heating frequency unit, a set of first heating units, a set of second heating units, a set of third heating units, and a switching arrangement configured to electrically allocate the set of first heating units to the first heating frequency unit, to electrically allocate the set of second heating units to the second heating frequency unit, and to electrically allocate the set of third heating units to at least one of the first and second heating frequency units.

Abstract: A cooktop device includes a set of first heating units, a set of second heating units, a set of intermediate heating units arranged spatially between the set of first heating units and the set of second heating units, a set of first inverters designed to operate the set of first heating units and the set of intermediate heating units, and a set of second inverters designed to operate the set of second heating units and the set of intermediate heating units.

Abstract: An induction cooktop apparatus includes an inductor, an insulating layer unit electrically insulating the inductor, and a detection coil for object recognition, said detection coil connected to the insulating layer.

Abstract: A hob apparatus includes a heating unit, a sensor unit separate from the heating unit and configured to include an electric resonant circuit and to detect a sensor signal, and a control unit configured to control the sensor unit and to analyze the sensor signal. The control unit determines in an operating state a state variable relating to the heating unit based on a phase shift and/or an amplitude ratio between the sensor signal and a further signal.

Abstract: A hob apparatus includes a sensor unit configured to detect a sensor signal, an electronic signal processing unit configured to further process and/or analyze the sensor signal, and a printed circuit board, on which the sensor unit and the signal processing unit are arranged together.
