Scheibenwaschanlaqe für KraftfahrzeugeWindscreen washer system for motor vehicles

Die Erfindung betrifft eine Scheibenwaschanlage für Kraftfahrzeuge mit einem Wasserschlauch zwischen einem Wasserreservoir und einer Spritzdüse.The invention relates to a windscreen washer system for motor vehicles with a water hose between a water reservoir and a spray nozzle.

Autoscheibenwaschanlagen sind heutzutage oft mit einer beheizbaren Wasserdüse und teilweise mit einem beheizbaren Wasserreservoir ausgestattet, um bei kalten Außentemperaturen ein Einfrieren der Scheibenwaschanlage zu verhindern. Trotz beheizbarer Wasserdüse besteht bei niedrigen Außentemperaturen die Gefahr, daß das Wasser im Wasserschlauch zwischen Wasserdüse und Wasserreservoir einfriert und damit die Scheibenwaschanlage nicht einsatzbereit ist. Wegen des verhältnismäßig kleinen Querschnitts des Wasserschlauchs wird die Gefahr des Zufrierens noch erhöht. Die Gefahr des Zufrierens besteht besonders stark nach langen Stillstandszeiten des Motors, da dann keine Abwärme vorhanden ist, um den Motorraum zu erwärmen und damit ein Einfrieren des Wasserschlauchs zu verhindern. Auch im Betrieb, wenn der Motor Abwärme produziert, kann das Problem nicht zufriedenstellend gelöst werden, weil durch die Luftströmung auch im Motorraum die erzeugte Wärme abführt undCar windscreen washer systems are now often equipped with a heated water nozzle and sometimes with a heated water reservoir to prevent the windscreen washer system from freezing up in cold outside temperatures. Despite the heated water nozzle, there is a risk at low outside temperatures that the water in the water hose between the water nozzle and the water reservoir will freeze and the windscreen washer system will therefore not be ready for use. The relatively small cross-section of the water hose increases the risk of freezing up. The risk of freezing up is particularly high after the engine has been idle for long periods, as there is no waste heat available to warm up the engine compartment and thus prevent the water hose from freezing up. Even during operation, when the engine produces waste heat, the problem cannot be solved satisfactorily because the air flow also dissipates the heat generated in the engine compartment and

G 9602 DEG 9602 EN

somit ein Zufrieren des Wasserschlauchs nicht ausreichend verhindert werden kann.This means that freezing of the water hose cannot be adequately prevented.

Die Erfindung hat die Aufgabe, eine Scheibenwaschanlage mit einem Wasserschlauch dahingehend zu verbessern, daß der Wasserschlauch nicht mehr zufrieren kann.The invention has the task of improving a windshield washer system with a water hose so that the water hose can no longer freeze.

Die Erfindung löst die gestellte Aufgabe dadurch, daß der Wasserschlauch zwischen dem Wasserreservoir und der Wasserdüse beheizbar ist. Auf diese Weise kann das Wasser im Wasserschlauch nicht mehr einfrieren und somit einen störungsfreien Betrieb der Scheibenwaschanlage sicherstellen.The invention solves the problem by heating the water hose between the water reservoir and the water nozzle. This prevents the water in the water hose from freezing, thus ensuring trouble-free operation of the windshield washer system.

Um den Wasserschlauch erwärmen zu können, kann dieser einen mit der Fahrzeugbatterie verbindbaren Heizdraht aufweisen. Unter Verwendung einer Zeitschaltuhr ist es auch in sehr kalten Jahreszeiten möglich, den Wasserschlauch schon einige Zeit vor Fahrtantritt zu erwärmen, damit die Scheibenwaschanlage unmittelbar nach Fahrtbeginn funktionstüchtig ist.In order to heat the water hose, it can have a heating wire that can be connected to the vehicle battery. By using a timer, it is possible to heat the water hose some time before starting the journey, even in very cold seasons, so that the windshield washer system is functional immediately after starting the journey.

Eine weitere Alternative, den Wasserschlauch zu erwärmen ist, ihn aus einem wärmeleitfähigen Material zu fertigen oder ihn mit einem solchen Material zu beschichten. Das Material kann an mindestens einer Stelle mit dem Motorblock thermisch gekoppelt sein. Wenn dieses wärmeleitfähige Material außerdem auch noch eine hohe Wärmekapazität aufweist, ist es auch nach langen Stillstandszeiten des Motors noch in der Lage ein Zufrieren des Wasserschlauchs zu verhindern. Selbstverständlich können auch das Wasserreservoir und die Spritzdüse beheizbar sein.Another alternative to heating the water hose is to make it out of a thermally conductive material or to coat it with such a material. The material can be thermally coupled to the engine block at least in one place. If this thermally conductive material also has a high heat capacity, it is still able to prevent the water hose from freezing even after long periods of downtime of the engine. Of course, the water reservoir and the spray nozzle can also be heated.

Damit jeder Fahrzeugbesitzer in den Genuß einer Scheibenwaschanlage mit beheizbarem Wasserschlauch gelangen kann, kann der beheizbare Wasserschlauch in bestehende Scheibenwaschanlagen nachrüstbar sein.So that every vehicle owner can enjoy a windscreen washer system with a heated water hose, the heated water hose can be retrofitted into existing windscreen washer systems.
