- the provision of the filtering bodies 33 and 34 on opposed portions of the contour of the tubular recess 3A of the opening 8, with respective channels 38 and 39 for the flow facilitates circulation of the air flow as the rotation of the drum 7 is reversed. This is because, depending on the direction of rotation of the drum, the drying air will preferentially flow into one or the other of the channels 38 and 39, and hence through the filtering body 33 or the one referenced 34, with doubtless advantages in terms of energy efficiency of the machine.
