Abstract
A blocking device for a door of an electric household appliance in which a plate sliding on a support is selectively blocked in use in a engaging position with a striker of the door by a pawl selectively mobile between an extracted position and a retracted position from/into a sliding seat thereof, in which positions the pawl respectively engages/does not engage a perforation of the plate; wherein the pawl is selectively blocked in an extracted position by means of an electromagnet having a winding and a core mobile along the axis of the winding and operatively associated to a mobile slide parallel to the axis of the winding between a first and a second limit stop position, only in the first of which a protrusion of the slide cooperates with the pawl; a retaining device of push-push type being operatively associated on one side to the slide and on the opposite side to a pre-loaded spring sandwiched between the retaining device and a shoulder fixed in use to the support; the push-push device being configured to block the slide in the first limit stop position following a single energizing pulse of the electromagnet and to release the slide, so as to allow the spring to take it to the second limit stop position, following two consecutive energizing pulses of the electromagnet.
