Abstract
(EN)
The present invention relates to a laundry dryer (1) comprising:- a cabinet (2) including a plinth (7) portion defining an inner plinth (7) volume (40) internal to the cabinet (2);- a first door (61) arranged in the plinth (7) portion of the cabinet (2);- a drum (3) rotatably supported in the cabinet (2);- a duct (18) defining a flow passage for process air exiting the drum (3);- a filter assembly (30, 80) positioned in a duct (18) section located in the inner plinth (7) volume (40) so as to filter (30) process air flowing therein, said filter assembly (30, 80) being at least partly located behind the first door (61);- said filter assembly (30, 80) including: a frame (31, 32) defining an inner frame (31, 32) volume (40) and having a frame (31, 32) shape; a filter (30) supported by the frame (31, 32) and defining a first filtering surface (32); a cleaning device positioned within said inner frame (31, 32) volume (40) for cleaning the first filtering surface (32) including a slidable wiper (330) to wipe the first filtering surface (32); wherein said slidable wiper (330) has a shape mating the frame (31, 32) shape of the inner frame (31, 32) volume (40) so that it can be translated with respect to the frame (31, 32) so as to wipe the first filtering surface (32), said cleaning device further including a fluff collector (50) apt to collect fluff removed from the first filtering surface (32) when the wiper (330) is translated onto such first filtering surface (32).
