An electric household appliance () has an electronic control unit () powered by a low-voltage power unit (), and a device () for reducing energy consumption of the electric household appliance in standby mode. The device includes: a bistable relay () which is switched by a low-voltage enabling signal (S) to a closed position to turn on the low-voltage power unit (), or is switched by a disabling signal (S) to an open position to turn off the low-voltage power unit (); a low-voltage capacitive power unit () designed to generate the low-voltage enabling signal (S); and a hand-operated control device () interposed between the low-voltage capacitive power unit () and the bistable relay () to supply the low-voltage enabling signal (S) to the bistable relay.

Device for reducing standby-mode energy consumption of an electric household appliance

An electric household appliance has a low-voltage capacitive power means () connected to an electrical power network () and is designed to generate a low-voltage (S,V). The low-voltage capacitive power means () comprise a capacitive dividing circuit () comprising a first () and second input terminal () connected to a first and second power line () at a first (V) and second (V) predetermined potential respectively; a first output terminal () adapted to generate said low-voltage enabling signal (S); first () and second charge-accumulating means () connected between said first and second input terminal; and at least one voltage limiter () connected parallel to said second charge-accumulating means () and designed to switch from a non-conducting to a conducting state when subjected to a voltage above a predetermined breakdown voltage (VZ). The first () and second charge-accumulating means () are designed so that the voltage (V) at the terminals of said second charge-accumulating means () is below the predetermined breakdown voltage (VZ).
