Abstract
A combination washer/dryer machine has a rotatable drum inside a cabinet. The drum has an external surface. A tub is positioned inside the cabinet. The drum is rotatable in the tub. The tub has an inner surface. A seal extends between the exterior surface of the drum and the inner surface of the tub forming a desired gap during both washing and drying operations and minimizing bypass of drying air during the drying operation.
