Title: Energy efficient clothes dryer

Abstract

This patent describes a heat pump dryer appliance for clothes and other washable products comprising, in combination: (a) a cabinet having a drum compartment with opposed front and rear walls and an auxiliary compartment having a front wall in common with the rear wall of the drum compartment; (b) a power driven rotatable tumbling drum housed in the drum compartment and having front and rear ends; (c) combined bearing and air seal means for rotatably supporting the drum on a fixed rotational axis within the drum compartment; (d) the bearing and air seal means including a first pair of annular members fixed respectively to the front and rear walls of the drum compartment, and a second pair of annular members disposed in sliding engagement with the first pair and fixed to respective ends of the drum; (e) the annular members being formed from rigid non-metallic plastic material; (f) each annular member of one pair defining a track and each annular member of the other pair defining a slider interfitting with the track; and (g) a resilient sealing gasket interposed between each slider and track.
