<p>Rotary-drum laundry dryer (1) comprising a revolving drum (3) structured for housing the laundry to be dried, a hot-air generator (6) structured to circulate a stream of hot air through said revolving drum (3), and a lower supporting base or socle (9) which is structured for resting on the floor and for housing at least part of the hot-air generator (6); the hot-air generator (6) in turn comprising: an air recirculating conduit (12) having its two ends connected to the revolving drum (3); air circulating means (13) which are located along the air recirculating conduit (12) and are structured to produce, inside the air recirculating conduit (12), an airflow (f) which flows through the revolving drum (3) and over the laundry inside the drum (3); and at least one heat exchanger (17) located along the air recirculating conduit (12) and structured to cool the moist air arriving from the rotatable drum (3) so to cause the condensation of the surplus moisture inside the airflow (f); a section of the air recirculating conduit (12) extending across the lower supporting base or socle (9), and being structured so as to house said at least one heat exchanger (17) of the hot-air generator (6); the air circulating means (13) being located outside said lower supporting base or socle (9), at the end-opening of said central of the air recirculating conduit (12), and comprising an impeller housing (15) which communicates with the end-opening of said central of the air recirculating conduit (12), and an impeller (16) which is housed in axially rotating manner inside the impeller housing (15) to generate said airflow (f); the air circulating means (13) additionally comprising a substantially funnel-shaped, intake manifold (20) which is fixed in a rigid and stable, though easily releasable, manner to said lower supporting base or socle (9), at the end-opening of said central of the air recirculating conduit (12), and extends within the impeller housing (15) towards the impeller (16).</p> |
