    (54) Method for the programming-timing of electrical household machines, advantageously dishwasher machines, and the relative programmer-timer


    (57) Method for the programming-timing of electrical household machines, advantageously dishwasher machines, the method being associated with a programmer-timer comprising at least mechanical main cam means (11), with relative tracks, together with rotary positioner motor means (13) for the definition of the cycles and specific functions of the dishwasher machine, at least printed circuit means (15) being included and having specialized multiple circumferential tracks, these printed circuit means cooperating and being advantageously coaxial with the mechanical main cam means, these specialized tracks of the printed circuit means being suitable to cooperate by sliding with brushes (16) that transfer and receive current, the brushes being capable of a relative circumferential movement in relation to the printed circuit means, the printed circuit means being connected electrically to at least one electronic card, the motor means that drive the main cam displacing that cam with a step-by-step movement to the desired function and displace the relative brushes on the specific contact/contacts of the printed circuit and then halt, the main cam thus displaced step-by-step activating the specific power contact, the contacts on the printed circuit connecting together two or more outputs of first electronic counter means with a plurality of outputs, each with determined times, the summation of the connected outputs defining the overall time of halting of the motor means driving the main cam and therefore the duration of the specific function. Programmer/timer for electrical household machines, advantageously dishwasher type machines, which comprises at least mechanical main cam means, with relative tracks, together with rotary positioner motor means for the definition of the cycles and specific functions of the dishwasher machine, at least printed circuit means being included and having specialized multiple circumferential tracks, these printed circuit means cooperating and being advantageously coaxial with the mechanical main cam means, these specialized tracks of the printed circuit means being suitable to cooperate by sliding with brushes that transfer and receive current, the brushes being capable of a relative circumferential movement in relation to the printed circuit means, the printed circuit means being connected electrically to at least one electronic card (18), the electronic card including at least first electronic counter means with a plurality of specialized outputs with determined times, the specialized tracks of the printed circuit including specific segments (28) associated univocally with the circumferential position of the main cam, the main cam advancing with a step-by-step movement, the circumferential position of the main cam defining the specific function activated, the specific segments of the specialized tracks connecting together two or more specialized outputs of the first electronic counter means so as to determine the period of duration of the halting between one step-by-step movement and another and therefore of the specific function.
