Patent ID: 8725454

Claim:
A method to compensate drying time in a drying cycle of an appliance for drying clothing articles, the appliance comprising a processor including an electronic control, a motor responsive to the electronic control to rotationally drive a dram arranged to receive the clothing articles, a heater to supply heated air to the drum, a moisture sensor to provide a moisture signal to the processor indicative of the moisture content of the clothing articles, and a memory to store values and a range of values, the electronic control being further configured to measure time, the method comprising: A. reading with the processor data indicative of a plurality of operator-selected parameters; B. measuring with the electronic control time elapsed between an initializing time and a target time; C. determining data indicative of a load weight within the drum and at least one type of restriction of the appliance; D. determining with the processor a range of values for a dryness target voltage by way of a table of predetermined values corresponding to said read and determined data; E. storing in the memory the values of the dryness target voltage; F. detecting with the moisture sensor a raw dryness voltage and comparing the detected dryness voltage relative to the range of values for the dryness target voltage; G. calculating with the processor an additional time as a function of a heat factor and a result of the comparing of the detected raw dryness voltage relative to the range of values for the dryness target voltage, wherein the calculating of the additional time is based on the following equation: T additional=max{(Heat Factor)×[Trtv(Multiplier−1)+Aggregate]; T minimum−Trtv}, wherein Tadditional presents the additional time, Heat Factor represents the heat factor, Trtv represents the target time, Multiplier represents a predetermined numerical value, aggregate represents a predetermined aggregate time value and Tminimum represents a minimum drying time value; and H. adding the additional time to the target time as compensation time for the drying cycle.
