The invention relates to a domestic appliance that can be switched between a stand-by mode and an operational mode, comprising a mains connection (21), to which an electrical mains voltage (UN) can be applied, a main supply unit (23), which is designed to provide an operating voltage (UB) from the mains voltage (UN) at the output (32) of the main supply unit, and an electrical load (29a to 29f), which is supplied with the operating voltage (UB). In the stand-by mode, at least the output (32) is disconnected from the mains connection (21) by means of an electrical switch (25). Voltage supply means (41) coupled to the mains connection (21) tap the mains voltage (UN) in the stand-by mode and produce a supply voltage (UV) from the mains voltage (UN), by means of which supply voltage the switch (25) is closed and thus the domestic appliance is switched from the stand-by mode to the operational mode. The invention further relates to a method for operating a domestic appliance.

摘要:
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.

The basis for the invention is a hob device, in particular an induction hob device, having at least one switching unit (10) by means of which at least one power supply line can be interrupted and connected, a current which is generated by means of a power supply voltage flowing through said line during at least one operating process and said power supply line leading to a first switching element (S 1 ). Said hob device also has at least one control device (14) which controls the switching unit (10) during the operating process in such a way that the switching unit (10) interrupts the power supply line during at least one first total time interval (t), and which initiates connection of the power supply line during the operating process immediately before and immediately after the first time interval (t) and initiates switching of the first switching element (S 1 ) which begins and ends during the first time interval (t). In order to achieve a high degree of efficiency, it is proposed that the first time interval (t) be shorter than the duration of half a period of the power supply voltage.
