Abstract
A laundry dryer having a cabinet, a rotatable drum, a duct defining a flow passage for process air, and a filter assembly positioned in the duct. The filter assembly includes a frame, a filter surface, and a cleaning device. The cleaning device includes wiper seat, a wiper, and a handle portion connected to the wiper portion. The cleaning device is pivotally attached to the frame to rotate around an axis, to be movable from a first resting position in which the handle is substantially completely housed in the wiper seat, to a plurality of wiping positions in which the wiper portion wipes the first filtering surface. In at least in one of the wiping positions, the handle portion protrudes from the wiper seat, and the handle portion is operable to perform the transition from the first resting position to any of the wiping positions.
