  • Patent number: 11591823
    Abstract: A door-locking device (1) including an actuator (20); a locking pin (11) controllable by the actuator (20) and adapted to cooperate with a movable latching slider (7) to lock a door of an electrical household appliance, the locking pin (11) being movable between a rest position, wherein the locking pin allows the latching slider (7) to move, and a lock position, wherein the locking pin prevents the latching slider (7) from moving; a detection switch (45) able to switch between an open position and a closed position following a movement of the latching slider (7), the detection switch (45) including a fixed contact element (45e) and a movable contact element (45c) resiliently stressed in closure towards the fixed contact element (45e), and a movable control member (46) interacting with the movable contact (45c). The control member (46) is also movable by a movement of the locking pin (11).

  • Patent number: 11299913
    Abstract: Door-locking device (1) comprising an electromechanical control device (10), which includes a locking pin (11) adapted to cooperate with a movable latching slider (7) for locking a door of an electric household appliance. The control device comprises a yoke (21), a magnet part (22) fixed to the yoke (21) and comprising a permanent magnet (23) polarized along a direction substantially perpendicular to the yoke (21), two electromagnets (26) arranged on opposite sides of the magnet part (22), and a rocking keeper (29) comprising two arms (29a, 29b) connected at an angle to each other, the keeper resting on a supporting surface (25) of the magnet part (22) 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 (27) of the electromagnets (26).
