Abstract

In a filter element comprising a filter insert (2) fixed in a frame (3), for introduction into a filter housing in a sealed manner, where the frame is at least partially provided with flexible sealing lips (4) for creating a seal with the housing, the lips are formed from a non-woven strip (at least at the frame side), such the strip can be refolded out and back in a longitudinal direction to form an edge seal.

Description

Die Erfindung betrifft ein Filterelement nach der Gattung des Hauptanspruchs, das aus einem Filtereinsatz aus Filterpapier oder dergleichen besteht und mit einem festen Rahmen umgeben ist, der ein dichtes Einfügen des Filterelements in ein Filtergehäuse ermöglicht.The Invention relates to a filter element according to the preamble of the main claim, which consists of a filter cartridge of filter paper or the like and surrounded by a solid frame, which is a tight insertion of the Filter element in a filter housing allows.

Es ist bereits aus der DE 195 48 197 C2 ein Filterelement bekannt, bei dem ein aus gefalteten Filterlagen gebildeter Filtereinsatz mit einem Rahmen aus einem polymeren Werkstoff gebildet ist. Der Rahmen weist bei diesem bekannten Filterelement eine einstückige elastisch verformbare Dichtlippe auf, die durch einen Gießprozess mit einem verflüssigbaren Werkstoff in einer geeigneten Gießform herausgebildet ist.It is already out of the DE 195 48 197 C2 a filter element is known in which a formed of folded filter layers filter insert is formed with a frame made of a polymeric material. The frame has in this known filter element on an integral elastically deformable sealing lip, which is formed by a casting process with a liquefiable material in a suitable mold.

Aufgabenstellungtask

Der Erfindung liegt die Aufgabe zugrunde, ein Filterelement der eingangs genannten Art so fortzubilden, dass eine einfach herzustellende Abdichtung des Filterelements ermöglicht wird.Of the Invention is based on the object, a filter element of the above so-called form such that a simple to produce Sealing of the filter element is made possible.

Vorteile der ErfindungAdvantages of invention

Das erfindungsgemäße Filterelement ist in vorteilhafter Weise geeignet, ausgehend von einem durch einen Rahmen gefestigten Filtereinsatz, der in ein Filtergehäuse dichtend einfügbar ist, wobei am Rahmen zumindest teilweise flexible Dichtlippen zur Abdichtung zum Filtergehäuse hin vorhanden sind, die gestellte Aufgabe mit den kennzeichnenden Merkmalen des Hauptanspruchs zu lösen. Dadurch, dass mindestens an einer Rahmenseite ein Vliesband zur Bildung der Dichtlippen in Längsrichtung des Rahmens heraus- und wieder zurückgefaltet ist, kann auf einfache Weise während des Herstellungsprozesses des Filterelements eine seitlich hervorstehende Dichtlippe herausgebildet werden.The filter element according to the invention is advantageously suitable, starting from a by a Frame-fixed filter cartridge sealing in a filter housing insertable is, wherein the frame at least partially flexible sealing lips for sealing to the filter housing are present, the task with the characterizing features of the main claim. Characterized in that at least on one side of the frame a nonwoven tape for Formation of the sealing lips in the longitudinal direction of Frame out and folded back is, can easily while the manufacturing process of the filter element a laterally projecting Sealing lip to be formed.

Gemäß einer bevorzugten Ausführungsform ist das Vliesband zum Rahmen hin und innerhalb der gefalteten Dichtlippe zum Beispiel mittels Hotmelts geklebt. In vorteilhafter Weise kann dabei die herausgefaltete Dichtlippe in einem vorgegebenen Winkel am Rahmen anliegen, beispielsweise nach oben oder unten gegen die Einschubrichtung bzw. senkrecht vom Rahmen abstehend.According to one preferred embodiment the nonwoven tape towards the frame and inside the folded sealing lip glued for example by hotmelts. In an advantageous way while the folded-out sealing lip at a predetermined angle on Frame abut, for example, up or down against the insertion direction or perpendicular to the frame.

Die Dichtlippen können dabei in Abhängigkeit von der erstrebten Dichtwirkung oder von den konstruktiven Gegebenheiten des Einbaus an den Längsseiten und/oder an den Stirnseiten des Filterelements angebracht werden. Das Filterelement kann in vorteilhafter Weise als Partikel- oder Kombifilter im Luftfilterbereich eingesetzt werden.The Sealing lips can depending on from the desired sealing effect or from the structural conditions the installation on the long sides and / or attached to the end faces of the filter element. The filter element can advantageously as a particle or Combi filters are used in the air filter area.

Zeichnungdrawing

Ein Ausführungsbeispiel des erfindungsgemäßen Filterelements wird anhand der Zeichnung erläutert. Es zeigen:One embodiment of the filter element according to the invention will be explained with reference to the drawing. Show it:

1 eine Ansicht eines erfindungsgemäßen Filterelements mit gefalteten Dichtlippen und 1 a view of a filter element according to the invention with folded sealing lips and

2 einen Detailschnitt durch den Rahmenbereich des Filterelements mit der Dichtlippe. 2 a detail section through the frame portion of the filter element with the sealing lip.

Beschreibung des Ausführungsbeispielsdescription of the embodiment

In 1 ist ein Filterelement 1 gezeigt, das beispielsweise zick-zack-förmig gefaltete Filterbahnen als Filtereinsatz 2 zur Luftfilterung aufweist. An den Stirn- und an den Längsseiten des Filterelements 1 befinden sich Teile eines Rahmens 3 zur Verstärkung des Filterelements 1, damit das Filterelement 1 in ein Filtergehäuse einfügbar ist.In 1 is a filter element 1 shown, for example, the zig-zag folded filter webs as a filter cartridge 2 having air filtering. At the front and at the long sides of the filter element 1 are parts of a frame 3 for reinforcing the filter element 1 , so that the filter element 1 can be inserted in a filter housing.

Zur Abdichtung des Filterelements 1 gegenüber der Aufnahme in dem hier nicht dargestellten Filtergehäuse weist der Rahmen 3 Dichtlippen 4 auf. Aus der Schnittdarstellung nach 2 ist erkennbar, das der Rahmen 3 aus aus einem Vliesband 5 gebildet ist, das zum Beispiel mit einem Hotmelt 6 auf den Filtereinsatz 2 aufgeklebt ist.For sealing the filter element 1 relative to the inclusion in the filter housing, not shown here, the frame 3 sealing lips 4 on. From the sectional view to 2 is recognizable, that the frame 3 from a fleece band 5 is formed, for example, with a hotmelt 6 on the filter cartridge 2 is glued on.

Die aus der 1 erkennbare Dichtlippe 4 ist nach dem Schnitt aus der 2 als eine Faltung ersichtlich, die durch heraus- und wieder zurückfalten des Vliesbandes 5 während der Aufbringung auf den Filtereinsatz 2 entstehen kann.The from the 1 recognizable sealing lip 4 is after the cut out of the 2 seen as a fold, by folding out and back again of the fleece band 5 during application to the filter cartridge 2 can arise.

Die herausgefaltete Dichtlippe 4 kann dabei in einem vorgegebenen Winkel am Rahmen 3 anliegen, beispielsweise nach oben oder unten gegen die Einschubrichtung abgewinkelt oder auch senkrecht vom Rahmen 3 abstehend.The unfolded sealing lip 4 can do this at a given angle on the frame 3 abutment, for example, angled up or down against the insertion direction or perpendicular to the frame 3 stand-off.
