Method of operating laundry treating appliance e.g. clothes dryer, involves initiating operational action for cycle of operation when comparison of difference signal with partially dry reference indicates that laundry load is partially dry

摘要

The method (140) involves tumbling (142) laundry load within the treating chamber and supplying (144) heated air to treating chamber. The surface temperature of laundry load is sensed (146) during tumbling to form temperature signal and the signal is processed (148) to form an upper envelope and a lower envelope. The difference between two envelopes is determined (150) to form difference signal and the signal is compared (152) to partially dry reference. The operational action for the cycle of operation is initiated (154) when the comparison indicates that laundry load is partially dry. An independent claim is included for laundry treating appliance.
