Abstract

A domestic appliance includes a mains connection at which an electrical mains voltage can be applied relative to a reference potential, a main supply unit supplying an electrical operating voltage from the mains voltage at its output, and at least one electrical consumer receiving the operating voltage. An electrical switch electrically isolates at least the output of the main supply unit from the mains connection, when the domestic appliance is in a standby mode. Provided separate from the main supply unit is a voltage supply which is coupled to the mains connection and which taps the mains voltage at the mains connection in the standby mode and supplies a supply voltage from the mains voltage for switching the electrical switch to an electrically conducting switching state to thereby switch the domestic appliance from the standby mode to an operating mode.

Claims

1-11. -11. (canceled)

12. A domestic appliance, comprising:

a mains connection at which an electrical mains voltage can be applied relative to a reference potential;

a main supply unit configured to supply an electrical operating voltage from the mains voltage at its output;

at least one electrical consumer configured for receiving the operating voltage;

an electrical switch electrically isolating at least the output of the main supply unit from the mains connection, when the domestic appliance is in a standby mode; and

a voltage supply separate from the main supply unit and coupled to the mains connection, said voltage supply tapping the mains voltage at the mains connection in the standby mode and supplying a supply voltage from the mains voltage for switching the electrical switch to an electrically conducting switching state to thereby switch the domestic appliance from the standby mode to an operating mode.

13. The domestic appliance of claim 12, further comprising an operating facility configured to generate an activation signal, when an operator actuates the operating facility to thereby switch the electrical switch to the conducting switching state.

14. The domestic appliance of claim 12, wherein only the voltage supply is connected to the mains connection in the standby mode.

15. The domestic appliance of claim 12, wherein the electrical switch is a mechanical switch.

16. The domestic appliance of claim 12, wherein the electrical switch is a relay.

17. The domestic appliance of claim 12, wherein the switch is disposed electrically between the mains connection and the main supply unit.

18. The domestic appliance of claim 12, further comprising a mains filter coupled to the main supply unit, said switch being disposed electrically between the mains connection and the mains filter.

19. The domestic appliance of claim 12, further comprising a power electronics unit, and a further switch to couple the power electronics unit to the mains connection, wherein the electrical switch is switchable to the electrically conducting switching state before the further switch is switched to an electrically conducting switching state, when the domestic appliance is switched from the standby mode to the operating mode.

20. The domestic appliance of claim 12, wherein the further switch is a mechanical, switch.

21. The domestic appliance of claim 19, wherein the further switch is switched to the conducting switching state as a function of a profile of the mains voltage.

22. The domestic appliance of claim 19, further comprising an inrush current limiter connected in series to the further switch to protect the further switch from an inrush current, said further switch being switchable as a function of a detected temperature of the inrush current limiter.

23. The domestic appliance of claim 12, wherein the voltage supply is configured to check the mains connection for any polarity reversal based on a tapped mains voltage in the standby mode.

24. A method for operating a domestic appliance, comprising:

applying an electrical mains voltage relative to a reference potential at a mains connection;

supplying an electrical operating voltage at an output of a main supply unit from the mains voltage;

supplying at least one electrical consumer with the operating voltage;

electrically isolating the main supply unit from the mains connection by an electrical switch, when the domestic appliance is in a standby mode;

coupling a voltage supply to the mains connection;

tapping the mains voltage at the mains connection in the standby mode; and

supplying a supply voltage from the mains voltage to switch the electrical switch to an electrically conducting switching state for switching the domestic appliance from the standby mode to an operating mode.
