Domestic appliance having a stand-by mode and method for operating such a domestic appliance
First Claim
1. 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;
a voltage supply separate from the main supply unit and coupled to the mains connection; and
an operating facility,said voltage supply tapping the mains voltage at the mains connection in the standby mode and supplying a supply voltage from the mains voltage only sufficient for operating the operating facility and switching the electrical switch to an electrically conducting switching state to thereby switch the domestic appliance from the standby mode to an operating mode, andthe operating facility configured to generate an activation signal, when an operator actuates the operating facility, to thereby switch the electrical switch to the electrically conducting switching state,wherein the electrical switch electrically isolates the output of the main supply unit from the mains connection until such time as the operating facility is actuated by the operator and generates the activation signal to the electrical switch to switch the domestic appliance from the standby mode to the operating mode, andwherein the domestic appliance is one of a domestic cooking appliance and a domestic laundry care appliance.

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.
