Claims18
An automatic dry control method for determining dryness using a plurality of temperature sensors that detects a change in temperature a process of drying in a dryer that comprises a drum periodically rotated by a motor during the process of drying, the motor rotating back and forth in a motor rotation period, the automatic dry control method comprising:
- calculating and storing continuously a temperature difference value (ΔT) between temperatures sensed by the plurality of temperature sensors;
- setting a calculation section to correspond to the motor rotation period for driving the drum, and calculating a section average value (AvgΔT) of a plurality of temperature difference values (ΔT) stored during the calculation section;
- and
- ending a drying operation when the calculated section average value (AvgΔT) is a predetermined dryness determination value (Δ).
