The present invention relates to a door-locking device for locking the door of household appliance, said door providing a closure hook (9), and at least a gasket provided on said door and/or on said household appliance, said device being characterised in that it provides a locking hook (1), coupling with said household appliance closure hook (9), a slider (2), movable along a direction substantially parallel to the household appliance wall on which the door is provided, a lever (3) compensating clearance of said gasket sealing closure, and kinematic means (5) coupling said locking hook (2) and said recovery lever (3), said locking hook (2) being rotably coupled (A) with said kinematic means (5) and being movable according to a direction substantially perpendicular with respect to the movement direction of said slider (2), elastic means (4) being further provided, aiming maintaining said kinematic means (5) in a door closure position, and interaction means (12, 13) between said slider (2) and said kinematic means (5) for locking position each other in the door closure position.
The device (1) comprises a rigid body (2) having a protruding structure (3) in which there is provided an opening (4) intended to receive a hook member (H) connected to the door. This body (2) has two seats (3a, 3b) provided on opposite sides of the protruding structure (3) and intended to engage, with play, with corresponding opposite edges (O1, O2) of an opening (O) provided in a panel (P) of the household appliance. A member (5) made of resilient material is provided in a first seat (3a). This member (5), owing to the engagement with the corresponding edge (1) of the opening (O) of the panel (P), is capable of being resiliently deformed by means of compression to a degree such as to allow subsequent engagement of the other seat (3b) with the corresponding other edge (O2) of the opening (O) of the panel (P).

A member (5) made of resilient material is mounted inside a first seat (3a) of said seats (3a, 3b). The arrangement is such that, owing to the engagement of the first seat (3 a) with the corresponding edge (1) of the opening (O) of the panel (P), the resilient member (5) is capable of making contact with a surface of the panel (P) close to the opening (O) and, after the subsequent engagement of the other seat (3b) with the corresponding other edge (O2) of the opening (O) of the panel (P), is able to remain engaged in a condition resiliently prestressed against the panel (P).
