Abstract: A cooking device includes a heating coil having at least two windings. A fixing device is provided to fix the heating coil at least partially mechanically in an assembled state. The fixing device includes a support unit and a retaining unit, which in the assembled state fixes each of the at least two windings separately on the support unit.

Abstract: A cook top with at least two heating elements includes a power electronics arrangement connected to a domestic single phase AC supply. The power electronics arrangement includes several power supply units, which each supply heating currents to one or more heating elements, and a switch arrangement with several electromechanical relays for connecting/disconnecting the power supply units to/from the heating elements. Output poles of at least two electromechanical relays associated with different power supply units are connected in parallel, wherein the parallel connection is permanently connected to at least one of the heating elements. This arrangement reduces the number of switching processes required for alternating use of a power supply device with several heating elements, and simplifies compliance with electromagnetic compatibility standards.

Abstract: A cooktop apparatus, in particular an induction cooktop apparatus, includes a switching unit configured to interrupt and establish current flow from a current supply, a first switching element receiving the current flow during an operating process, a control apparatus, which controls the switching unit during the operating process such that the switching unit interrupts the current supply during a first time interval which has a duration of less than of half a period of the power supply voltage. The control apparatus causes the current supply to be connected during the operating process immediately before and immediately after the first time interval. The first switching element begins switching and ends switching during the first time interval.

Abstract: A cooker hob device, in particular to an induction cooker hob device, includes at least one switching unit and at least one control apparatus. In order to obtain a high degree of efficiency, the control apparatus is constructed to automatically prompt the at least one switching unit in at least one operating cycle to switch in at least one entire first time interval using at least one switching parameter having a value which changes at least substantially continuously.

Abstract: A heating apparatus, in particular a hob heating apparatus, with at least one heating connection for at least one heating element and at least one frequency unit. In order to provide a heating apparatus of the generic type with relatively high operational reliability, it is proposed that the heating apparatus comprises a protective unit, which is provided for determining the existence of a conducting path between the frequency unit and the at least one heating connection.

Abstract: A domestic-appliance-operating device, in particular a hob-operating device, includes an operating panel having a touch operating surface, a sensor plate which is arranged beneath the touch operating surface, and a touch sensor unit. A signal-transmission unit connects the sensor plate to the touch sensor unit in an electrically conductive manner by a conducting element and has at least one screening unit.
