    (54) Device for controlling the drying of laundry in a laundry drier


    (57) A device for controlling the drying of laundry in a laundry drier comprises a microprocessor (2) adapted to generate an enabling signal for permitting the identification of drying cycles selected by first, second or third selector means (3, 4, 5). The microprocessor (2) is energized from the electric circuit of the machine in series with the heater element (6), and is electrically separated, by means of opto-insulators (26, 30) or the like, from the low-volt­age electric components of the device. These components in particular comprise an integrator circuit (12) and a comparator (21) for controlling the drying degree of the laundry.
    By the selection of the drying cycles to be performed, the control device permits the automatic execution of the respective cycles with simultaneous control of the laundry drying process.
