Abstract
A laundry dryer includes a rotatable drum and an air delivery system. The air delivery system can include a reversible blower that provides air at a first flow rate when operated in a first direction and provides air at a second lower flow rate when operated in an opposite second direction. The drum can be a reversibly rotatable drum that is rotatable in a first and an opposite second direction, and the dryer can include a drive motor that both rotates the drum and operates the blower. Drum and blower reversal may be controlled to optimize drying efficiency and also reduce stress on the drive system. A moisture delivery system can provide moisture (e.g., water mist or steam) into the drum while air is being provided at the lower second flow rate, and during drum rotation (tumbling).
