  • Patent number: 4470204
    Abstract: A control device for a laundry drier of the kind in which mechanical movement of the laundry load in a drum causes the article(s) constituting the load to form an electrically resistive connection between contact electrodes 5 and 6 in the drum. An a.c. sensing current is fed from a transformer T1 via the load and through a series capacitor C2 such that the voltage across the capacitor C3 is an inverse function of the state of dryness of the articles. This voltage is compared in a comparator TR1 with a reference voltage Vref which is chosen so that the comparator TR1 produces an output signal when the articles of the load have reached a predetermined dryness. Any electrostatic charges developed in the load are suppressed by a unidirectional low impedance shunt comprising a diode D8 and a resistor R12 in series.
