Abstract

The high speed windscreen washer has the washer jets (5) in the ends of air scooo ducts (2) under the bonnet and drawing air from theslipstream through the ducts. This provides an angled airstream to take the washer fluid to the windscreen. The intakes of the scoops are contoured into the bonnet line while the outlets are angled upwards at the rear edge of the bonnet cover (1) to follow the airflow lines. The water is effectively applied to the windscreen when travelling at high speeds and without overspray.

Description

~Vorrichtung zum Reinigen der Windschutzscheibe von Kraftwagen'1 Die Erfindung betrifft eine Vorrichtung zum Reinigen der Windschutzscheibe von Kraftwagen, die einen etwa in Fahrzeuglängsrichtung verlaufenden, im Bereich vor der Windschutzscheibe endenden Kanal aufweist. dem über eine weiter vorn am Fahrzeug angeordnete Lufteintrittsöffnung Luft zugeführt wird, die am anderen Ende etwa parallel zur Windschutzscheibe austritt.~ Device for cleaning the windshield of motor vehicles'1 The The invention relates to a device for cleaning the windshield of motor vehicles, the one running approximately in the longitudinal direction of the vehicle, in the area in front of the windshield having ending channel. via an air inlet opening located further forward on the vehicle Air is supplied, which exits at the other end approximately parallel to the windshield.

Eine derartige Anordnung ist bekannt aus der DE-OS 28 30 51.Such an arrangement is known from DE-OS 28 30 51.

Sie dient dort dem Verhindern des abheben der Scheibern<ischerblätter bei hoher Fahrtgeschwindigkeit.There it serves to prevent the disc blades from lifting off at high speed.

Ein weiteres Problem, das hinsichtlich der Scheibenreinigung bei hohen Geschwindigkeiten auftritt, ist die Ablenkung der über Düsen auf die Windschutzscheibe gerichteten Waschflüssigkeitsstrahlen. Um dieses Prob]em zu lösen, sind bereits aufwendige Vorrichtungen zur Anpassung der Diisenstellung an die jeweiligen Störfaktoren vorgeschlagen worden, wie dies z. B.Another problem related to window cleaning at high Speeds occurring is the deflection of the nozzles on the windshield directed washer fluid jets. To solve this problem are already Elaborate devices for adapting the position of the diaphragm to the respective disruptive factors has been proposed as z. B.

der DE-OS 26 oo 379 zu entnehmen ist.the DE-OS 26 oo 379 can be found.

Der vorliegenden Erfindung lag die Aufgabe zugrunde, unter Vermeidung solcher aufwendigen Verstelidüsen eine Möglich keit zu schaffen, auch bei hohen Geschwindigkeiten eine einwandfreie Beaufschlagung der Windschutzscheibe mit Waschflüssigkeit sicherzustellen.The object of the present invention was to avoid it Such complex Verstelidüsen a possibility to create, even at high Speeds a proper application of the windshield with washer fluid to ensure.

Dies wird erfindungsgemäß bei einer Vorrichtung der vorstehend beschriebenen Gattung dadurch erreicht, daß im Endbereich des Kanals mindestens eine der Beaufschlagung der Windschutzscheibe mit Waschwasser dienende Düse angeordnet ist.According to the invention, this is done in a device as described above Type achieved in that at least one of the impact in the end region of the channel the windshield with washing water serving nozzle is arranged.

Der bei hohen Geschwindigkeiten aus dem Kanal austretende starke Luftstrahl verhindert mit Sicherheit eine unerwiinschte Ablenkung der Waschflüssigkeitsstrahlen, ohne daß dazu ein zusätzlicher Bauaufwand erforderlich wäre.The strong jet of air emerging from the duct at high speeds certainly prevents undesired deflection of the washing liquid jets, without additional construction costs being required.

Der Gegenstand der Erfindung soll im folgenden anhand eines in der Zeichnung dargestellten Ausführungsbeispiels näher erläutert werden.The object of the invention is to be based on one in the Drawing illustrated embodiment will be explained in more detail.

In der Zeichnung zeigen Fig. 1 eine perspektivische Darstellung des Vorderteils eines erfindungsgemäß ausgestatteten Personenkraftwagens, und Fig. 2 einen Schnitt nach der Linie II-II in Fig. 1, in größerem Elaßstab.In the drawing, Fig. 1 shows a perspective view of the Front part of a passenger car equipped according to the invention, and FIG. 2 a section along the line II-II in Fig. 1, in a larger Elaßstab.

Der in der Zeichnung dargestellte Personenkraftwagen weist im Bereich seiner Motorhaube 1 zwei Kanäle 2 auf, die jewei ls einen Lufteinlaß 3 im Bereich der Motorhaube 1 aufweisen und die in einem Bereich vor der Windschutzscheibe 4 in einem Luftauslaß enden, der der austretenden Luft einen etwa parallel zur Windschutzscheibe 4 gerichteten Verlauf gibt. Am Ende jedes Kanals 2 ist eine Düse 5 angeordnet, die aus einem nicht dargestellten Vorratsbehälter über eine Pumpe mit Waschflüssigkeit versorgt wird. Diese Waschflüssig keit wird dann praktisch im Schutz des aus dem Kanal 2 austretenden Luftstrahls auf die Windschutzscheibe 4 befördert, ohne daß eine wesentliche Ablenkung durch Fahrtwind, Luftwirbel od. dgl. erfolgen kann.The passenger car shown in the drawing has in the area his hood 1 has two channels 2, each ls an air inlet 3 in the area the bonnet 1 and those in an area in front of the windshield 4 end in an air outlet, the exiting air is approximately parallel to the windshield 4 directional course there. At the end of each channel 2, a nozzle 5 is arranged, which from a storage container (not shown) with washing liquid via a pump is supplied. This washing liquid is then practically in the protection of the Channel 2 exiting air jet transported to the windshield 4 without a significant distraction by airflow, air vortex or the like. Can take place.
