The present invention concerns a door-lock device (1) for a closing door (P) of an household appliance (L) said door (P) being provided with a recess, said door-lock device (1) comprising a casing (2), a slider (3), arranged within said casing (2), a locking hook (5) comprising a body (51) and a locking portion (52), said body (51) having a cam shape (54) which abuts on said slider (51), said locking hook (5) being capable to assume a rest position, in which said locking portion (52) is disengaged from said recess, and an operative position, in which said locking portion (52) is inserted into, and engaged with, said recess, and pushing means (4), for normally keeping said slider (3) in contact with said cam surface (54), such that, when said door (P) is closed, said locking hook (5) passes from said rest position to said operative position, said cam shape (54) of said locking hook (5) initially compressing said pushing means (4), so that said pushing means (4) accumulate a potential energy and said slider (3) exerts a resistance to the closing of said door (P), and, then, allowing said pushing means (4) to release said accumulated potential energy, so that said slider (3) exerts a return action on said locking hook (5) and on said door (P); and vice versa when said door (P) is opened. |
