ABSTRACT:
A clothes dryer has a heat source, preferably a heat pump, a rotating drum, and means to generate flow of air from the heat source to an inlet in the drum. At least two outlets are separated from each other in the drum to enable higher air flow rates without increase in pressure drop, resulting in reduced drying time.
