Abstract
A method for detecting the presence of a synthetic fabric load during an automatic drying cycle in an automatic dryer avoids premature termination of the automatic drying cycle and ensures that the synthetic fabric items are dried according to a user'"'"'s desired dryness level. The presence of the synthetic fabric load is detected by determining a duration of a first heating cycle, determining a duration of a second heating cycle, and determining the presence of the synthetic fabric load based on the durations of the first and the second heating cycles.

17. An automatic clothes dryer for drying fabric items according to an automatic drying cycle, the dryer comprising:
-
a drying chamber for receiving fabric items;
an air circulation system for forcing air through the drying chamber;
a heater for heating the air in the air circulation system; and
a controller operably coupled to the heater for governing the heater through multiple heating cycles to implement the automatic drying cycle and comprising a timer for determining a duration of each heating cycle;
wherein the controller detects the presence of a synthetic fabric load based on the durations of the heating cycles. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30)
