Abstract
Description
Die
Erfindung betrifft eine Scheibenreinigungsanlage, insbesondere für
Fahrzeugscheinwerfer, mit einem Gehäuse (
Scheibenwaschvorrichtungen
für Fahrzeuge, wie sie aus der
Aufgabe der Erfindung ist es, eine Scheibenreinigungsanlage gemäß dem Oberbegriff des Anspruchs 1 derart weiterzubilden, dass die Funktion der Scheibenreinigungsanlage sicher ist, auch wenn durch von außen in das Gehäuse eindringendes Wasser Schmutzpartikel und/oder Eispartikel in einem Hohlraum zwischen Düsenträger und Außenwand des Gehäuses verbleiben können. Diese Aufgabe wird für eine Scheibenreinigungsanlage, insbesondere für Fahrzeugscheinwerfer, mit einem Gehäuse, mit einem mittels einer druckausübenden Reinigungsflüssigkeit teleskopartig von einer Ausgangsstellung innerhalb des Gehäuses in eine axial aus dem Gehäuse heraus stehenden Arbeitsstellung verschiebbaren Düsenträger, der eine Durchgangsöffnung für die Reinigungsflüssigkeit aufweist, dem auf einer dem Gehäuse abgewandten Seite mindestens eine Düse zugeordnet ist und zwischen dem und dem Gehäuse eine Dichtungseinrichtung angeordnet ist, die zur Abdichtung der Reinigungsflüssigkeit in jeder Stellung des Düsenträgers dient, dadurch gelöst, dass das Gehäuse innen einen feststehenden stabförmigen Ständer aufweist, der eine Durchgangsöffnung für die Reinigungsflüssigkeit aufweist, der mindestens so lang wie der Verstellweg des Düsenträgers ist und auf den der Düsenträger aufgeschoben ist, wobei zwischen dem Ständer und dem Düsenträger die Dichtungseinrichtung angeordnet ist.task The invention is a windscreen cleaning system according to the Further develop the preamble of claim 1 such that the function of Windscreen cleaning system is safe, even if through from the outside into the housing penetrating water dirt particles and / or Ice particles in a cavity between nozzle carrier and outer wall of the housing can remain. This task is for a windscreen cleaning system, in particular for vehicle headlights, with a housing, with one by means of a pressure-exerting cleaning liquid telescopic from a home position within the housing in an axially out of the housing standing working position sliding nozzle holder, which has a passage opening for the cleaning liquid, the one on one the housing facing away from at least one nozzle is assigned and between the housing and a sealing device is arranged, which seals the cleaning fluid in each position of the nozzle carrier, thereby solved that the case inside a fixed having rod-shaped stand, which has a passage opening for the cleaning liquid, the at least as long as the adjustment of the nozzle carrier is and on which the nozzle carrier is pushed, being between the stand and the nozzle carrier the sealing device is arranged.
Der besondere Vorteil der Erfindung besteht darin, dass ein Verschmutzen der Dichtungseinrichtung durch ihre versteckte geometrische Anordnung kaum möglich ist. Weiterhin ist die Dicht- bzw. Reibfläche der Dichtungseinrichtung kleiner als bei bekannten Scheibenreinigungsanlagen. Deswegen ist die Dichtungseinrichtung kostengünstig herstellbar und die Verstellkraft des Düsenträgers entsprechend klein.Of the particular advantage of the invention is that a contamination the sealing device by their hidden geometric arrangement barely is possible. Furthermore, the sealing or friction surface the sealing device smaller than in known windscreen cleaning systems. Therefore, the sealing device is inexpensive to produce and the adjusting force of the nozzle carrier correspondingly small.
Nach einer bevorzugten Ausführungsform der Erfindung sind der Ständer und der Düsenträger rohrförmig ausgebildet, wobei der Ständer an der Innenseite eines Bodens des Gehäuses angeformt ist und eine Außenwand des Gehäuses zylindrisch ist und den Ständer koaxial umgibt. Dadurch ist der Ständer einteilig mit dem Gehäuse und somit kostengünstig herstellbar.To a preferred embodiment of the invention are the Stand and the nozzle holder tubular formed, with the stand on the inside of a Bottom of the housing is formed and an outer wall the housing is cylindrical and the stator coaxial surrounds. As a result, the stand is integral with the housing and thus inexpensive to produce.
Weiterhin ist es vorteilhaft, wenn die Dichtungseinrichtung von einer ringförmigen Dichtung gebildet ist, die in einer in den freien Endabschnitt des Ständers umlaufenden Nut angeordnet ist, wobei die Dichtung umlaufend dicht an der Innenseite der Durchgangsöffnung des Düsenträgers anliegt. Als Dichtung kann eine einfache ringförmige Runddichtung verwendet werden. Obwohl die Reibung bei einer im Querschnitt runden Dichtung höher ist als bei einer Lippendichtung ist diese hier wegen der kleinen Reibfläche machbar. Dadurch ist die Dichtungseinrichtung kostengünstig herstellbar.Furthermore, it is advantageous if the sealing device is formed by an annular seal which is arranged in a circumferential groove in the free end portion of the stator, wherein the seal rests circumferentially close to the inside of the passage opening of the nozzle carrier. As a seal, a simple annular round seal can be used. Although the friction is higher for a round in cross-section seal than at a lip seal this is feasible because of the small friction surface. As a result, the sealing device is inexpensive to produce.
Das Gehäuse der Scheibenreinigungsanlage baut möglichst kurz, wenn der Ständer in der Ausgangsstellung des Düsenträges zumindest mit seinem größten Teil seiner Länge innerhalb des Düsenträgers angeordnet ist.The Housing of the windscreen cleaning system builds as possible short, when the stand in the starting position of the nozzle carrier at least with most of its length is disposed within the nozzle carrier.
Weiterhin ist es vorteilhaft, wenn der Düsenträger an seinem dem Inneren des Gehäuses zugewandten Randbereich einen nach außen ragenden umlaufenden Vorsprung aufweist, zwischen dem und der Außenwand des Gehäuses umlaufend ein schmaler Spalt besteht. Dadurch ist ein hinterer Hohlraum des Gehäuses der den Ständer umgibt, vor Verschmutzungen geschützt.Farther it is advantageous if the nozzle carrier at his the interior of the housing facing edge region a outwardly projecting circumferential projection, between the and the outer wall of the housing circumferentially a narrow Gap exists. This is a rear cavity of the housing which surrounds the stand, protected from contamination.
Ein weiterer Vorteil ist, wenn der zur Schmutzabweisung dienende Vorsprung des Düsenträgers zusätzlich zur Halterung einer den Düsenträger umgebenden Schraubenfeder ist, die zwischen dem Vorsprung und einem Wandabschnitt des Gehäuses unter Vorspannung eingesetzt ist, wobei der Wandschnitt des Gehäuses von einem umlaufenden Randbereich einer Öffnung eines hülsenförmigen Aufsetzteils gebildet ist, das auf die Außenwand des Gehäuses aufgeschoben und an dieser befestigt ist.One Another advantage is when the serving for dirt repellency projection the nozzle carrier in addition to the holder a coil spring surrounding the nozzle carrier is that between the projection and a wall portion of the housing is used under prestressing, the wall section of the housing from a peripheral edge region of an opening of a sleeve-shaped Aufsetzteils is formed on the outer wall of the housing deferred and attached to this.
Die Dichtung ist einfach und schnell montierbar, wenn bei nicht montierten hülsenförmigen Aufsetzteil der Ständer mit dem die Dichtungseinrichtung aufweisenden Endabschnitt aus einer Öffnung der Außenwand des Gehäuses herausragt.The Seal is easy and quick to assemble, if not assembled sleeve-shaped Aufsetzteil the stand with the sealing device comprising the end portion of an opening of the Outside wall of the housing protrudes.
