(54) A door lock device of increased safety, particularly for domestic electrical appliances


(57) A door locking device comprising:
a support structure (2) with an aperture (3) into which a hook member (4) connected to this door (P) is introduced when the door (P) is closed,
a retainer slide (7) movable between a working position in which it is able to obstruct the aperture (3) partially and retain the hook member (4), and a rest position in which it is able to allow disengagement of the hook member (4); and
an electro-mechanical control device (27) including a movable lock member (27) displaceable from an inactive to a locking position, in which it is able respectively to allow and prevent the passage of the retainer slide (7) from the working position to the rest position. The device further includes a safety mechanism (30) including a feeler member (31b) sensitive to the position of the hook member (4) when the door (P) is closed and
an intervention member (34) associated with the feeler member (31b) and operable, when the hook member (4) is disengaged from the feeler member (31b) whilst the lock member (27) is in the locking position, to interact
with the lock member (27) causing it to return to the release position, and
with the retainer slide (7) locking it in the said working position.
