Hier wird die Ansaugluft für den Trockenluftstrom über eine Filtereinrichtung geführt, um diese Luft für einen hygienischen Trocknungsvorgang von Staubpartikeln und dgl. zu befreien. Der Aufnahmekörper ist zylindrisch ausgebildet und weist an seinem Umfang Ansaugöffnungen für eine in das Filterinnere gerichtete Luftströmung auf. Der Filtereinsatz kann zur Reinigung aus dem Aufnahmekörper entnommen werden. Ein derartiger Ansaugluftfilter ist für die Ausfilterureg der Flusen aus dem Prozessluftstrom nicht geeignet.DE 196 44 400 A1 discloses such a tumble dryer with a filter device is known in which a cup-shaped filter insert is inserted into a receptacle and is arranged in the intake air flow for the dry air. Here is the intake air for the Dry air flow passed through a filter device to keep this air hygienic Freeing the drying process from dust particles and the like. The receiving body is cylindrical and has on its circumference suction openings for one in the Air flow directed inside the filter.

Aus der DE 196 53 570 A1 ist eine Filtereinrichtung für einen Handstaubsauger bekannt. Die Filtereinrichtung ist topfförmig ausgebildet und auf der Lufteintrittseite zum Gehäuse hin abgedichtet, so dass der Luftstrom in das Innere des Filterkörpers geleitet wird. Die Staubpartikel setzen sich auf der Innenseite der Filterfläche ab. Der topfförmige Filterkörper weist eine äußere Filterfläche in der Art eines offenen Beutels auf, der von einer Tragstruktur gehalten wird. Das geschlossene untere Ende des Beutels ist in das Topfinnere gewölbt angeordnet und bildet so die im Inneren des Filterkörpers angeordnete innere Filterfläche. Dadurch wird die wirksame Filterfläche vergrößert. Die Tragstruktur für den Filterbeutel ist federelastisch ausgebildet und expandiert unter der Einwirkung des Saugluftstromes. Bei Wegfall der Luftströmung geht das Traggestell in die ursprüngliche Form zurück.
