Abstract
Description
Die Erfindung betrifft eine Waschflüssigkeitsdüse zur Reinigung einer Scheibe an einem Fahrzeug, insbesondere der Windschutz- oder Heckscheibe.The The invention relates to a washing liquid nozzle for cleaning a window on a vehicle, in particular the Windscreen or rear window.
Waschflüssigkeitsdüsen können derart beschaffen sein, dass diese einen divergierenden, flachen und damit fächerförmigen (Waschflüssigkeits-)Sprühstrahl ausbringen, der sich in der Sprührichtung, also von der Waschflüssigkeitsdüse in Richtung Fahrzeugscheibe, horizontal zunehmend verbreitert und zumindest beim Auftreffen auf die Fahrzeugscheibe einen rechteckförmigen Querschnitt aufweist.Washer fluid nozzles may be such that they have a divergent, flat and thus fan-shaped (washing liquid) spray deploy, in the spray direction, so from the Washing liquid nozzle in the direction of the vehicle window, horizontally increasingly widened and at least when hitting the vehicle window has a rectangular cross-section.

Dadurch, dass die Fahrzeugscheiben gekrümmt sind, kommt es, insbesondere bei den fächerartig aufgeweiteten Waschflüssigkeitsstrahlen, die mit einem rechteckigen Querschnitt auf die Fahrzeugscheibe auftreffen, zu Waschflüssigkeitsverlusten, da die Waschflüssigkeit in den Randbereichen des aufgefächerten Sprühstrahls über das vorbestimmte Benetzungsfeld auf der Fahrzeugscheibe hinaus gesprüht wird und dort für die Scheibenreinigung weitgehend ungenutzt bleibt.Thereby, that the vehicle windows are curved, it comes, in particular in the fan-like expanded washing liquid jets, the impinge on the vehicle window with a rectangular cross-section, to wash liquid losses, since the washing liquid in the edge regions of the fanned spray over sprayed the predetermined wetting field on the vehicle window is largely unused and there for the windscreen cleaning remains.
Es ist Aufgabe der Erfindung, eine Waschflüssigkeitsdüse zur Reinigung einer Scheibe an einem Fahrzeug nach dem Oberbegriff des Anspruchs 1 so zu gestalten, dass durch diese ein Waschflüssigkeitsstrahl erzeugt wird, der nur oder im Wesentlichen nur das vorbestimmte Benetzungsfeld auf der jeweiligen Scheibe besprüht.It It is an object of the invention to provide a washing liquid nozzle for cleaning a disc on a vehicle according to the preamble of claim 1 to be designed so that through this a washing liquid jet is generated, the only or substantially only the predetermined Wetting field sprayed on the respective disc.
Diese Aufgabe wird bei einer Waschflüssigkeitsdüse nach dem Oberbegriff des Anspruchs 1 mit dessen kennzeichnenden Mitteln gelöst. Vorteilhafte Ausgestaltungen sind in den Unteransprüchen aufgeführt.These Task is with a washing liquid after the preamble of claim 1 with its characterizing means solved. Advantageous embodiments are in the subclaims listed.
Die Erfindung besteht in einer in einem Düsenkörper angeordneten und mit einem (Waschflüssigkeits-)Zuführkanal verbundenen Waschflüssigkeitsdüse mit einer Düsenöffnung zur Erzeugung eines quer zur Sprührichtung horizontal fächerförmig aufgeweiteten Waschflüssigkeitsstrahles. Die Düsenöffnung ist horizontal und schlitzförmig ausgebildet, weist einen ebensolchen Öffnungsschlitz auf und ist dabei mit einem an die Scheibe angepassten Krümmungsradius um eine Krümmungsachse gekrümmt, die parallel und im vertikalen Abstand unter der Sprühstrahlmittelachse verläuft. Mit dieser Waschflüssigkeitsdüse wird ein entsprechend der Scheibenkrümmung gewölbter fächerförmiger Sprühstrahl gezielt auf die Fahrzeugscheibe gesprüht, der das Benetzungsfeld auf dieser vergrößert. Zugleich wird der Verlust von Waschflüssigkeit reduziert, und es wird die Reinigungsleistung verbessert. Da die Scheibenkrümmung der Fahrzeugscheiben bei verschiedenen Fahrzeugtypen wenig unterschiedlich ist, kann die Waschflüssigkeitsdüse universell eingesetzt werden.The invention consists in a arranged in a nozzle body and connected to a (washing liquid) supply channel washing liquid nozzle having a nozzle opening for generating a horizontally fan-shaped transverse to the spray direction expanded washing liquid jet. The nozzle opening is formed horizontally and slit-shaped, has just such an opening slot and is curved with a radius of curvature adapted to the disk about a curvature axis which runs parallel and at a vertical distance below the spray jet center axis. With this washing liquid nozzle, a fan-shaped spray jet arched in accordance with the disc curvature is sprayed specifically onto the vehicle window, which enlarges the wetting field on it. At the same time, the loss of washing liquid is reduced, and the cleaning performance is improved. Since the disc curvature of the vehicle windows is little different for different types of vehicles, the washer fluid nozzle can be used universally.
An der Oberseite der Düsenöffnung, also an deren oberer, konkav gewölbter Fläche, kann zusätzlich eine gekrümmte Leitschaufel angeordnet sein, die die Ausbildung des Waschflüssigkeitsstrahls zu einem gekrümmten fächerförmigen Sprühstrahl unterstützt.At the top of the nozzle opening, so at the upper, concavely curved surface, may be additional a curved vane can be arranged, which is the training of the washing liquid jet to a curved Fan-shaped spray supported.
Vorteilhaft
kann die Waschflüssigkeitsdüse eine modifizierte
Fächerstrahldüse mit einer schlitzartigen Düsenöffnung
sein, die gegenüber den üblicherweise eingesetzten
Fächerstrahldüsen im Bereich zwischen der Mündung
