The present invention relates to a Door-locking device () for a household appliance (E), said household appliance (E) being of the type comprising a door provided with a lug (), said door locking device () comprising a containment casing (), fixable to said household appliance (E), a hook (), arranged into said containment casing (), capable of moving from a disengagement position, in which said lug () does not contact said hook (), to an engagement position, in which said lug () is engaged with said hook () and said hook () is free to move along the movement direction of said lug (), an abutment element () fixed on said containment casing (), and elastic means (), interposed between said hook () and said abutment element (), wherein when said hook () is in said disengagement position, said elastic means () are compressed, and when said hook () is in said engagement position, said elastic means () expand, so that said hook () moves.

Device for locking a household appliance door

A door-locking device () including an actuator (); a locking pin () controllable by the actuator () and adapted to cooperate with a movable latching slider () to lock a door of an electrical household appliance, the locking pin () being movable between a rest position, wherein the locking pin allows the latching slider () to move, and a lock position, wherein the locking pin prevents the latching slider () from moving; a detection switch () able to switch between an open position and a closed position following a movement of the latching slider (), the detection switch () including a fixed contact element () and a movable contact element () resiliently stressed in closure towards the fixed contact element (), and a movable control member () interacting with the movable contact (). The control member () is also movable by a movement of the locking pin ().

Door locking device, particularly for electrical household appliances

Door-locking device () comprising an electromechanical control device (), which includes a locking pin () adapted to cooperate with a movable latching slider () for locking a door of an electric household appliance. The control device comprises a yoke (), a magnet part () fixed to the yoke () and comprising a permanent magnet () polarized along a direction substantially perpendicular to the yoke (), two electromagnets () arranged on opposite sides of the magnet part (), and a rocking keeper () comprising two arms () connected at an angle to each other, the keeper resting on a supporting surface () of the magnet part () so as to be able to rock between a first and a second position respectively in contact with one or the other of the cores () of the electromagnets ().
