Abstract

A rotary-drum laundry dryer (1) has 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 comprises: 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 (0 which flows through the revolving drum (3) and over the laundry inside the drum (3); and at least one heat exchanger (15) 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 segment (12c) 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 (15) of the hot-air generator (6). The hot-air generator (6) additionally comprises air filtering means (18) located along the air recirculating conduit (12), upstream of said at least one heat exchanger (15), and a rigid, grid-like protective assembly (19) which is firmly fixed inside the segment (12c) of the air recirculating conduit (12), downstream of the filtering assembly (18) and upstream of the at least one heat exchanger (15), so as to bar the segment (12c) of the air recirculating conduit (12) for preventing a generic hard foreign body from reaching the heat exchanger (15).
