Abstract

Anordnung und Verfahren zum Ausblasen eines Abluftstroms (11), insbesondere aus einem Haushaltsgerät (30); wobei an einer stromaufwärtigen Seite (13) eines luftdurchlässigen und schallabsorbierenden Schaumfilters (12) der Abluftstrom (11) im Wesentlichen in einer Hauptströmungsrichtung in das luftdurchlässige und schallabsorbierende Schaumfilter (12) strömen kann; wobei an einer stromabwärtigen Seite (14) des Schaumfilters (12) eine das Schaumfilter (12) zumindest teilweise abdeckende luftundurchlässige Prallfläche (15) angeordnet ist, so dass der Abluftstrom (15) in dem Schaumfilter (12) aus seiner Hauptströmungsrichtung abgelenkt wird; und wobei stromaufwärts zu dem Schaumfilter (12) ein in einem Halterahmen (23) befindliches Luftfilter (24) angeordnet ist, wobei der Halterahmen (23) zwischen dem Luftfilter (24) und dem Schaumfilter (12) ein Gitter (25) aufweist, auf dem sich das Schaumfilter (12) abstützen kann.

Figure imgaf001
Arrangement and method for blowing out an exhaust air stream (11), in particular from a domestic appliance (30); wherein on an upstream side (13) of an air-permeable and sound-absorbing foam filter (12), the exhaust air flow (11) can flow into the air-permeable and sound-absorbing foam filter (12) substantially in a main flow direction; wherein an air-impermeable baffle (15) at least partially covering the foam filter (12) is disposed on a downstream side (14) of the foam filter (12) so that the exhaust air flow (15) in the foam filter (12) is deflected from its main flow direction; and wherein an air filter (24) located in a holding frame (23) is arranged upstream of the foam filter (12), the holding frame (23) having a grid (25) between the air filter (24) and the foam filter (12) where the foam filter (12) can be supported.
