ABSTRACT:
The invention provides a process and a device for eliminating lint deposits in the hot-air circuit of clothe washers and dryers. The spiral backflow line (211) of the blower (210) and the air-heating chamber (230) are connected below by a line (220) which, along with the spiral backflow line (211) and the heating chamber (230), is filled with water up to a specific height (H) on the basis of the manometric backflow height (hm) of the blower so as to create a cyclical vortex effect that dislodges the lint deposits when the blower (210) is in operation.
