An apparatus (10) includes an engagement element (11), fitted on a household appliance casing for being releasably held by a retaining element (16) fitted on the door (D). The engagement element (11) includes a support body (12); and a striker (14), releasably coupled to the retaining element (16) and is mobile between a retracted position and an extracted position. When the striker (14) is coupled to the retaining element (16) and assumes the retracted position and the extracted position, respectively, the door (D) is in a complete closing condition and in a pre-opening condition, respectively. A stop mechanism (18) moves from a release condition, to liberate said striker (14), to a locking condition, to hold said striker (14), in said retracted position; a driver controls movement of the stop mechanism (18). The stop mechanism (18) has a manually controlled safety element (18a) and is moveable to constrain the stop mechanism.

1. Apparatus for controlling closing of a door of a household appliance, in particular for a washing machine; said door being arranged to close an inner chamber obtained in a casing of said household appliance and communicating outside through an inlet opening; said apparatus comprising an engagement element, which is configured to be fitted on one of said casing and said door and arranged for being held in a releasable manner by a retaining element configured to be fitted on the other one of said door and said casing to constrain said door to said casing, when using said household appliance; wherein said engagement element comprises:a support body configured to be fitted on one of said casing and said door;a striker adapted to be coupled in a releasable manner to said retaining element, and mounted so as to move relative to said support body between a retracted position and an extracted position; when said striker is coupled to said retaining element and assumes said retracted position and said extracted position, said door being suited to be, respectively:in a complete closing condition, in which said door closes said access opening in a fluid-tight manner, andin a pre-opening condition, in which said door is spaced apart from said access opening, so as to establish a fluid communication between said inner chamber and an environment outside said casing;a stop mechanism tending to move: from a release position, in which said stop mechanism is adapted to liberate said striker, thus allowing said striker to move from said retracted position to said extracted position, when said striker is coupled to said retaining element,to a locking position, in which it is adapted to hold said striker, when said striker is in said retracted position;wherein said stop mechanism comprises: a slider, which is mounted so as to move relative to said support body from a locking position, in which said slider is arranged to hold said striker in said retracted position, to a release position, in which said slider allows said striker to move from said retracted position to said extracted position due to an electrical excitation of said driving means; andan elastic member tending to hold said slider in said locking position;a safety element, which is manually controllable by a user and is movable between: a liberation arrangement, in which the safety element allows the stop mechanism to move between the locking condition and the release condition, andan inhibition condition, in which the safety element forcedly constrains the stop mechanism in the release condition; wherein said stop mechanism constrains said striker, thus preventing said striker from moving towards said extracted position, when said striker is in said retracted position and said stop mechanism is in the locking condition;wherein said safety element is a lever or appendage capable of projecting from said slider in a position in which the safety element is accessible to a user and is configured to be grabbed by the user, wherein said lever or appendage has a portion capable of cooperating with a shaped profile; said shaped profile being delimited by a slot in said support body and in which said portion is configured for being engaged and locked in the inhibition arrangement wherein in said inhibition condition, said portion is constrained by said shaped profile, preventing said slider from moving to said locking position; said safety element being carried by said slider and preventing said slider from moving to said locking position when said safety element is in the inhibition condition;electrically operated driving means, wherein when the safety element is in the liberation arrangement, the driving means control movement of said stop mechanism from said locking position to said release position. 2. The apparatus according to claim 1, wherein said stop mechanism acts in a transverse direction relative to the moving direction of said striker. 3. The apparatus according to claim 1, wherein said slider and said striker have respective complementary profiles which cooperate one with the another and which are configured for allowing, by interference, forced movement of said striker from the extracted position to the retracted position against the action of said elastic member. 4. The apparatus according to claim 1, wherein said stop mechanism comprises: a cursor, which is movable by said driving means and is mounted so as to move relative to said support body from an inactive position, in which said cursor allows said slider to move from said release position to said locking position due to action of said elastic member, to an active position, in which said cursor drags said slider from said locking position to said release position against the action of said elastic member, when said driving means are electrically excited; andan elastic element, which holds said cursor in said inactive position. 5. The apparatus according to claim 4, wherein said slider and said cursor are coupled with a sliding clearance. 6. The apparatus according to claim 4, wherein said elastic element exerts a return elastic force on said cursor, which is greater than the return elastic force exerted by said elastic member on said slider. 7. The apparatus according to claim 4, wherein said slider and/or said cursor is able to be moved in a direction that is orthogonal to a moving direction of said striker. 8. The apparatus according to claim 1, wherein said driving means control the movement of said stop mechanisms from said locking condition to said release condition, when said driving means are excited by a passage of electric current, thus moving from a normally extended condition to contracted position, in which said driving means respectively allow said stop mechanism to assume said locking condition and bring said stop mechanism to said release condition.
