Description
Die Saugleistung von Staubsaugern nimmt bekanntlich mit dem Füllgrad des Filterbeutels ab. Andererseits hängt aber die Saugleistungskonstanz von der Filterzusetzung ab, d.h. davon, wieweit die Flächen des nicht-gefüllten Beutelteiles mit Feinstaut) überzogen sind. Normalerweise setzt sich bei einem glatten Beutel der Feinstaub sofort gleichmässig an der gesamten Innenfläche desselben ab, so dass die Saugleistungskonstanz verhältnismässig rasch vermindert wird, obwohl der Beutel nur zu einem geringen Teil gefüllt ist.As is well known, the suction power of vacuum cleaners decreases with the filling level of the filter bag. On the other hand, it depends The suction power constancy depends on the filter clogging, i.e. on the extent to which the surfaces of the unfilled bag part with Feinstaut) are covered. Normally, with a smooth bag, the fine dust immediately settles evenly across the entire bag Inner surface of the same, so that the suction power constancy is reduced relatively quickly, although the bag is only partially full.
Die Neuerung schafft für einen Papierfilterbeutel dadurch Abhilfe, dass der Beutel durch Einbringung von Falten quer zur Strömungsrichtung in wenigstens zwei sich gegenüberstehenden Seitenflächen balgartig ausgebildet ist. Auf dieseThis creates the innovation for a paper filter bag Remedy that the bag by making folds transversely to the flow direction in at least two opposing Side surfaces is designed like a bellows.

Weise entstehen im Innern des Beutels Flächen, die vom Saugstrom abgewandt sind, sowie diesen gegenüberstehende Flächen, die dem Saugstrom zugekehrt sind. Die letztgenannten Flächen werden während des Betriebes vom Saugstrom angeblasen, so dass sieh dort kein Feinstaub festsetzen kann bzw. solcher immer wieder abgeblasen wird. Dadurch wird die Saugleistungskonstanz des Gerätes erhöht.In the interior of the bag there are areas that are from the Suction flow are turned away, as well as these opposing surfaces that face the suction flow. The latter Surfaces are blown by the suction flow during operation, so that no fine dust can settle there can or such is blown off again and again. This increases the suction power of the device.
In der Zeichnung ist ein Ausführungsbeispiel eines neuerungsgemässen Papierfilterbeutels dargestellt. Der .Beutel ist in bekannter Weise oben mit einer Lufteintrittsöffnung 1 versehen und unten geschlossen. Mit der Öffnung 1 wird er innerhalb eines Staubsaugers in bekannter Weise an einem Saugstutzen angeschlossen. Geraäss der Neuerung ist der Beutel balgartig ausgebildet, indem seine Seitenwände mit Falten versehen sind. Dadurch entstehen quer zur durch Pfeile S dargestellten Strömungsrichtung der Saugluft Innenflächen J5 und 4. Die Flächen j5 sind von der Strömungsrichtung abgewandt, und der Feinstaub 5 wird sich vorwiegend an diesen Flächen absetzen. Die Flächen h hingegen sind dem Saugstrom zugekehrt und werden von diesem während des Betriebes freigeblasen. Es wird sich also an diesen Flächen 4 kein Feinstaub festsetzen, so dass die Saugleistungskonstanz gegenüber den Filterbeuteln mit einer durchgehend ebenen Innenfläche beträchtlich erhöht ist.In the drawing, an embodiment of a paper filter bag according to the innovation is shown. The bag is provided in a known manner with an air inlet opening 1 at the top and is closed at the bottom. With the opening 1 it is connected in a known manner to a suction nozzle within a vacuum cleaner. According to the innovation, the bag is designed like a bellows in that its side walls are provided with folds. This creates inner surfaces J5 and 4 transversely to the direction of flow of the suction air shown by arrows S. The surfaces j5 face away from the direction of flow, and the fine dust 5 will predominantly settle on these surfaces. The surfaces h, on the other hand, face the suction flow and are blown free by it during operation. No fine dust will settle on these surfaces 4, so that the suction power constancy is considerably increased compared to the filter bags with a continuously flat inner surface.
