Abstract

The present invention relates to a household appliance (1 ) comprising a structure (2) having a load opening (3) and a door (6) adapted to close said opening (3). A door locking device allows to lock the door (6) when the latter is closed. The door locking device comprises an electric actuator (13) acting in response to a control signal received at a control input (A, B). The household appliance (1) also comprises a capacitor (28) and a switch (27) connected in a manner such that in a first position of said switch (27) the capacitor (28) is connected to a voltage source (30), hence getting charged, and in a second position of said switch (27) the capacitor (28) is connected to the control input (A5B) of the electric actuator (13), hence getting discharged.
