The invention regards a locking device for the closing door of a washing and drying machine, constituted of a body of containment that houses a locking wheel for the door latch, subject to the action of elastic means, a sliding bolt capable of preventing the rotation of said wheel and a time-delay mechanism fitted with a locking pawl for said sliding bolt. The wheel is fitted with a cavity that presents a surface tilted with respect to the plane of rotation, so as to resolve the force it exerts on the bolt, when a pulling is exerted on the door while the device is in a closed and locked position.

INTERLOCK MECHANISM FOR THE CLOSING DOOR OF WASHING MACHINES OR TUMBLE DRYERS
In door interlock mechanisms, used for locking the door of washing machines or tumble dryers, the closed or open state of the door of the machine is detected by reading the resistive value of a circuit in which a switch is placed in series. The interlock mechanism according to the invention envisages providing the door interlock with two contacts that make it possible to check, independently, whether the device is in the position with the door closed and locked and whether the door catch is inserted in the device. The device comprises an open-door contact (15), actuated in the closing position by a shaped portion (12) of a first slider (7) and in the opening position by a shaped portion (14) of a second slider (8) which, under the action of elastic means (10), interacts with the door catch (19).
The present invention relates to a selector (100) for switching-on, switching-off and selection of the operating programmes of an appliance, in particular of an electrical household appliance, comprising means (20, 30, 40, 60, 70) for automatic opening of the power supply circuit at the end of the selected operating programme. The selector (100) according to the present invention is characterized in that it integrates an auto switch-off function, on special command of the control electronics of the machine, directed at safety and energy saving, while also maintaining the functions of manual setting of the operating programme and of manual switching on and off.
The invention regards a locking device for the closing door of a washing and drying machine, constituted of a body of containment (1) that houses a locking wheel (3) for the door latch, subject to the action of elastic means (4), a sliding bolt (5) capable of preventing the rotation of said wheel (3) and a time-delay mechanism fitted with a locking pawl for said sliding bolt (5). The wheel (3) is fitted with a cavity (10) that presents a surface (11) tilted with respect to the plane of rotation, so as to resolve the force it exerts on the bolt (5), when a pulling is exerted on the door (1) while the device is in a closed and locked position.
