    (54) A laundry drying control device for a clothes drier


    (57) A laundry drying control device for a clothes drier comprising an electri­cal heating element divided into two portions (5, 6), portion (5) being adapted to be short-circuited by a driver (16) controlled by an electronic comparator (14) or by a logical AND gate (15).
    The device is adapted to control the run of "acrylic" drying cycles by switching on the maximum power of only the portion (6) of the heating element until the operating drying temperature is reached, and then switching on a reduced heating power via the two portions (5, 6) of the heating element.
    The device is adapted to control the run of "extra dry" drying cycles by switching on the maximum heating power and then the reduced heating power for a supplementary period after the end of drying.
