Description

Die vorliegende Erfindung betrifft einen Filter zur Filterung der in den Innenraum eines Kraftfahrzeuges eingeführten Luft.The present invention relates to a filter for filtering the air introduced into the interior of a motor vehicle.

Die Belüftung bzw. die Frischluftzufuhr in den Innenraum von Kraftfahrzeugen erfolgt meistens durch die Lüftungsanlage, wobei die Aussenluft häufig durch Einschalten des Gebläses angesaugt und in den Innenraum, direkt oder nach Durchströmen des Kühlaggregates einer Klimaanlage, eingeblasen wird. Nachteilig ist dabei, dass die Frischluft ungefiltert, d.h. durch Strassenstaub und Schadstoffe belastet, durch die Lüftungsdüsen den Insassen des Wagens ins Gesicht geblasen wird. Das wird verständlicherweise als störend und unangenehm empfunden und führt dazu, dass, insbesondere auf vielbefah­ renen Strassen, die Lüftung abgeschaltet wird um der Beläs­ tigung zu entgehen.The ventilation or fresh air supply to the interior of Motor vehicles are mostly done through the ventilation system, the outside air often by turning on the fan sucked in and into the interior, directly or after flow of the cooling unit of an air conditioning system is blown in. The disadvantage here is that the fresh air is unfiltered, i.e. polluted by street dust and pollutants by which Air vents blown in the face of the car's occupants becomes. This is understandably considered bothersome and uncomfortable felt and leads to the fact that, streets, the ventilation is switched off around the vent escaping.

Die Erfindung bezweckt einen einfachen und preisgünstigen Filter zu schaffen, mittels dem die in den Innenraum von Kraftfahrzeugen eingeführte Luft gefiltert werden kann. Der erfindungsgemässe Filter entspricht den Merkmalen des kennzeichnenden Teiles des Patentanspruchs 1.The invention aims to be simple and inexpensive To create filters by means of which the interior of Air introduced into motor vehicles can be filtered. The filter according to the invention corresponds to the features of characterizing part of claim 1.

Zweckmässigerweise besteht das Filtermaterial aus elasti­ schem Schaumstoff. Es können mehrere Filtermaterial-Lagen vorgesehen sein, wobei zwischen zwei Filtermaterial-Lagen ein tuchartiger Feinfilter eingelegt sein kann. Hierbei ist es sinnvoll, dass die aufeinander liegenden Lagen-Oberflächen zweier Filtermaterial-Lagen in Zick-Zack-Form gewellt sind. Dies schafft auf einfache Weise eine verrutschsichere Verbindung zweier Filtermaterial-Lagen und bewirkt darüber hinaus eine weit grössere wirksame Fläche des dazwischen­ liegenden tuchartigen Feinfilters. Das Filtermaterial kann grobporig oder feinporig sein oder aus mindestens einer grobporigen Filtermaterial-Lage und aus mindestens einer feinporigen Filtermaterial-Lage bestehen. Zur einfachen Erkennung der Porengrösse eines Filtermaterial-Elementes können dabei die verschiedenen Lage-Elemente verschiedene Farben aufweisen. Zudem kann der Filter mit Aktivkohle versehen, z.B. besprüht sein.The filter material expediently consists of elasti chemical foam. There can be several layers of filter material  be provided, one between two filter material layers cloth-like fine filter can be inserted. Here it is it makes sense that the superimposed layer surfaces two layers of filter material are corrugated in a zigzag shape. This easily creates a slip-proof Connection of two layers of filter material and effect in addition, a much larger effective area in between lying cloth-like fine filter. The filter material can be large-pored or fine-pored or from at least one coarse-pored filter material layer and from at least one fine-pored filter material layer. For easy Detection of the pore size of a filter material element the different location elements can be different Show colors. In addition, the filter can be activated carbon provided, e.g. be sprayed.

Aus filterungstechnischer Sicht optimal ist, dass der Filter ausschliesslich aus luftdurchlässigen Bestandteilen besteht, keine Klappergeräusche verursachen kann und darüber hinaus sogar geräuschdämmend wirkt. Der Filterblock lässt sich be­ quem einführen und zum Reinigen oder Ersetzen wieder heraus­ ziehen. Besonders vorteilhaft ist auch, dass der Filterblock, entsprechend den unterschiedlichen Grössen des Luftansaug­ gehäuses der Kraftfahrzeuge, zugeschnitten werden kann. Schliesslich kann der Filter auf einfache Weise den unter­ schiedlichen Fahrleistungen sowie den Umweltgegebenheiten individuell angepasst werden, indem nur eine oder mehrere Filtermaterial-Lagen verwendet werden. Auch der Feinfilter kann weggelassen werden.From a filtering point of view it is optimal that the filter consists exclusively of air-permeable components, can not cause rattling noises and beyond even has a noise-reducing effect. The filter block can be insert and remove again for cleaning or replacement pull. It is also particularly advantageous that the filter block, according to the different sizes of the air intake housing of the motor vehicles, can be tailored. Finally, the filter can easily under different mileage and environmental conditions can be customized by just one or more Filter material layers are used. Even the fine filter  can be omitted.

Nachfolgend werden anhand von zwei Zeichnungsfiguren zwei Ausführungsbeispiele des Erfindungsgegenstandes beschrieben.In the following, two will be used based on two drawing figures Exemplary embodiments of the subject matter of the invention are described.

Fig. 1 zeigt ein erstes Ausführungsbeispiel mit zwei Lagen Schaumstoff-Filtermaterial und einem dazwischen liegenden Feinfilter, und Fig. 1 shows a first embodiment with two layers of foam filter material and a fine filter in between, and

Fig. 2 zeigt ein zweites Ausführungsbeispiel mit drei Lagen Schaumstoff-Filtermaterial mit zwei jeweils dazwischen liegenden Feinfiltern. Fig. 2 shows a second embodiment with three layers of foam filter material with two fine filters in between.

Die Filtermaterial-Lagen 1 und 2 liegen mit ihren zick-zack- förmig gewellten Oberflächen 6 aufeinander. Dazwischen ist Lagen 1 und 2 sind in ihrer äusseren Form identisch und passen nahtlos ineinander, wenn eine Lage um 180° zur anderen gedreht wird.The filter material layers 1 and 2 lie on one another with their zig-zag wavy surfaces 6 . In between, layers 1 and 2 are identical in their outer shape and fit together seamlessly when one layer is rotated 180 ° to the other.

Im zweiten Ausführungsbeispiel liegt zwischen den beiden Filtermaterial-Lagen 1 und 2 zusätzlich eine dritte Filter­ material-Lage 3. Diese dritte Lage ist beidseitig zick-zack- förmig gewellt, um zwischen die Filtermaterial-Lagen 1 und 2 zu passen. Auch sind hier gleich zwei Feinfilter 4 und 5 vorhanden.In the second exemplary embodiment, a third filter material layer 3 is located between the two filter material layers 1 and 2 . This third layer is corrugated on both sides in a zigzag shape to fit between the filter material layers 1 and 2 . Two fine filters 4 and 5 are also present here.

Der Lufteintritt erfolgt in beiden Beispielen in Richtung des Pfeiles a.In both examples, air enters in the direction of arrow a .

Die Filtermaterial-Lagen 1, 2, 3 können so gewählt werden, dass die Luft zuerst eine grobporige Lage durchströmt und den Filter zuletzt aus einer feinporigen Lage wieder verlässt. The filter material layers 1 , 2 , 3 can be selected so that the air first flows through a coarse-pore layer and finally leaves the filter again from a fine-pore layer.

Der Winkel der zick-zack-förmigen Oberflächenwellung 6 der Filtermaterial-Lagen 1, 2, 3 kann unterschiedlich steil sein. Entsprechend variiert die wirksame Filterfläche des in die Oberflächenwellung 6 hineingefalteten Feinfilters 4 bzw. 5. Bedingt durch die elastische Ausbildung des Filters und auch durch die Möglichkeit den Filter passend zurechtschneiden zu können, sind die meisten Kraftfahrzeuge auch nachträglich leicht und kostengünstig mit einem Luftfilter ausrüstbar. Der Schaumstoff der Filtermaterial-Lagen 1, 2, 3 kann beispielsweise aus Polypropylen bestehen.The angle of the zigzag-shaped surface corrugation 6 of the filter material layers 1 , 2 , 3 can be of different steepness. The effective filter area of the fine filter 4 or 5 folded into the surface corrugation 6 varies accordingly. Due to the elastic design of the filter and also the possibility of being able to cut the filter to size, most motor vehicles can also be easily and inexpensively equipped with an air filter. The foam of the filter material layers 1 , 2 , 3 can for example consist of polypropylene.
