Abstract: A pressure sensor including: a casing fluid-tightly divided into a first and a second chamber by a deformable membrane and means for connecting the first chamber to the environment and the second chamber to a tank for an operative fluid of an electric household appliance for detecting the level thereof according to a deformation of the membrane upon the establishment of a differential pressure in the two chambers; wherein the membrane carries toward the first chamber a rigid disc operatively associated with a switch carried by the casing to either close or open the switch upon the deformation of the membrane beyond a predetermined entity.

Abstract: A door lock device for an electric household appliance with movable latch, in particular a dryer, where the latch is carried by the door of the electric household appliance rotating on a plane, normally perpendicular to a door rotation axis, including a frame carried in use by the casing of the electric household appliance and provided with striker means for the latch; where the striker means are obtained on a pair of opposite jaws carried by the frame adjacent to each other and movable against the bias of elastic means and where the frame is provided with guiding means for the jaws adapted to cause the jaws to be driven apart from each other in response to a traction exerted in use on the latch, said elastic means and guiding means being arranged so that the movement of the jaws occurs on a plane arranged perpendicular in use to the rotation plane of the latch.

Abstract: A mechanism for locking a door of an electric household appliance is improved in that a slider jaw is hinged to a body of a slider in such manner that, by its tooth, it snaps or releases a head of a latch and that the slider jaw is provided with an opening finger, and a mechanism housing is provided with a hindering element, which thrusts the opening finger of the slider jaw, when the slider moves in direction of the force of the spring, so that the slider jaw gets open. The slider body and the slider jaw are preferably made of different materials: the slider body of a polyoxymethylene copolymer and the slider jaw of a polyamide or of a ZL4 alloy having a composition Zn:A14:Cu1. The proposed mechanism is not susceptible to plastic deformation of the junction area between the slider body and the slider jaw.
