Abstract
Description
Die Erfindung betrifft eine Scheibenwaschanlage für ein Kraftfahrzeug nach den Merkmalen des Oberbegriffs des Patentanspruchs 1.The The invention relates to a windscreen washer system for a motor vehicle according to the features of the preamble of claim 1.
In der kalten Jahreszeit bilden sich bei Temperaturen unter 0° Celsius Eisschichten auf den Scheiben eines Kraftfahrzeuges. Die Wischblätter frieren an der mit Eis überzogenen Scheibe an und müssen von Hand oder durch Bedienen der Wischer ruckartig von der Scheibe gelöst werden. Durch das ruckartige Lösen werden die aus einer Gummimischung bestehenden Wischerblätter geschädigt. Die geschädigten Wischerblätter hinterlassen beim Wischen auf der Scheibe Schlieren und Streifen, die die Sicht des Fahrers beeinträchtigen.In the cold season are formed at temperatures below 0 ° Celsius Ice layers on the windows of a motor vehicle. The wiper blades freeze on the ice-coated disc and must by hand or by operating the wiper jerkily from the disc be solved. Become a jerky release the wiper blades made of a rubber compound damaged. The damaged wiper blades leave streaks and streaks when wiping on the glass, which affect the driver's view.
Die
Aufgabe der vorliegenden Erfindung ist es eine Scheibenwaschanlage für ein Kraftfahrzeug weiterzubilden, damit angefrorene Wischerblätter schnell, umstandslos und zuverlässig von einer Scheibe des Kraftfahrzeuges gelöst werden.task The present invention is a windscreen washer for develop a motor vehicle, so that frozen wiper blades quickly, uncomplicated and reliable from a disc of the motor vehicle be solved.
Die Aufgabe wird erfindungsgemäß durch die Merkmale des Patentanspruchs 1 gelöst.The The object is achieved by the features of claim 1.
Scheibenwaschanlagen umfassen generell Wischerblätter, Druckleitungen und Düsen, aus denen eine Reinigungsflüssigkeit aus einem Behälter auf eine Scheibe eines Kraftfahrzeuges sprühbar ist. Die erfindungsgemäße Scheibenwaschanlage weist einen Zusatzbehälter für hochkonzentrierte Enteisungsflüssigkeit auf. Zum zuverlässigen Lösen der angefrorenen Wischerblätter wird hochkonzentrierte Enteisungsflüssigkeit über die Druckleitung mittels Düsen auf die Scheibe oberhalb der Wischerblätter gesprüht, so dass diese auf die Wischerblätter herunterläuft, und sie so von der Scheibe löst. Durch die Verwendung der erfindungsgemäßen Scheibenwaschanlage wird die Eisschicht zwischen den Wischerblättern und der Scheibe in kürzester Zeit abgetaut. Somit ist ein Lösen der festgefrorenen Wischerblätter von Hand nicht mehr erforderlich. Dadurch wird der Verschleiß der Wischerblätter zuverlässig reduziert. Die Beeinträchtigung der Sicht des Fahrers durch Schlieren und Streifen wird minimiert.Washer systems generally include wiper blades, pressure lines and nozzles, from which a cleaning fluid from a container a disc of a motor vehicle is sprayable. The inventive Windscreen washer has an additional container for highly concentrated deicing fluid. To the reliable Releasing the frozen wiper blades becomes highly concentrated deicing fluid the pressure line via nozzles on the disc above sprayed the wiper blades, leaving them on the wiper blades will run down, and so on the disc releases. By the use of the invention Windscreen washer is the ice layer between the wiper blades and the disc defrosted in no time. Thus, one is Loosen the frozen wiper blades by hand not necessary anymore. This will reduce the wear of the Wiper blades reliably reduced. The impairment The driver's view through streaks and streaks is minimized.
Die Benetzung der Scheibe kann über die bereits vorhandene Druckleitung und Düsen der Scheibenwaschanlage erfolgen.The Wetting of the disc can be over the already existing Pressure line and nozzles of the windscreen washer system.
In einer Weiterbildung der Erfindung ist vorgesehen, dass zur Scheibenwaschanlage ein Bedienelement gehört, mit dem verschieden abgestufte Wischerfrequenzen ansteuerbar sind. Die Benetzung der Wischerblätter kann vorteilhaft als Vorstufe zur niedrigsten Wischerfrequenz implementiert werden. Dies bietet den Vorteil, dass die Enteisungsfunktion in das vorhandene Bedienelement der Scheibenwaschanlage, beispielsweise einem Drehstufenschalter im Lenkstockhebel, kostengünstig integrierbar ist.In a development of the invention is provided that the windshield washer a control belongs, with the different graded wiper frequencies are controllable. The wetting of the wiper blades can advantageously implemented as a precursor to the lowest wiper frequency become. This offers the advantage that the defrost function in the existing control of the windscreen washer, for example a rotary switch in the pitman arm, cost-effective is integrable.
In einer anderen vorteilhaften Ausgestaltung der Erfindung kann das Bedienelement zur Auslösung der Benetzung der Wischerblätter als separates Bedienelement z. B. in einer Mitteltunnelkonsole oder in einer Instrumententafel vorgesehen werden. Das Bedienelement kann ein Knopf oder Schalter sein und im direkten Zugriffsbereich des Fahrers liegen.In another advantageous embodiment of the invention, the Operating element for triggering the wetting of the wiper blades as a separate control z. B. in a center tunnel console or in be provided an instrument panel. The control element can be a button or switch and in the direct access area of the Driver lie.
Vorzugsweise ist die Scheibenwaschanlage zum Enteisen der Wischerblätter der Front- und/oder Heck- und/oder Scheinwerferwaschanlage zugeordnet. Dies gewährleistet optimalen Komfort und Sicherheit, da vor Antritt der Fahrt alle angefrorenen Wischerblätter von den Scheiben oder Scheinwerferabdeckungen zuverlässig gelöst werden können. Von besonderem Vorteil ist die Verwendung der erfindungsgemäßen Scheibenwaschanlage zur Enteisung bei den immer mehr zum Einsatz kommenden LED-Scheinwerfern. Bei diesen wird im Gegensatz zu den Halogenscheinwerfern kaum eine Wärmestrahlung emittiert. Daher ist ein Abtauen der Eisschicht durch die Wärmestrahlung bei LED-Scheinwerfern nicht möglich. Deshalb ist es von besonderem Vorteil, wenn die Scheinwerferabdeckungen mit dem Enteisungsflüssigkeit besprühbar sind. Dadurch ist zuverlässig sichergestellt, dass die Leuchtkraft der LED-Scheinwerfer bei Antritt der Fahrt nicht beeinträchtigt ist.Preferably is the windscreen washer for defrosting the wiper blades assigned to the front and / or rear and / or headlight washer. This ensures optimum comfort and safety since before starting the ride all frozen wiper blades reliable from the panes or headlight covers can be solved. Of particular advantage is the use of the windscreen washer according to the invention for de-icing in the more and more used LED headlamps. In these, unlike the halogen headlights barely one Heat radiation emitted. Therefore, a defrost of the ice sheet not possible with the heat radiation of LED headlamps. Therefore, it is of particular advantage when the headlight covers be sprayed with the deicing fluid. This reliably ensures that the luminosity the LED headlamp is not affected when starting the journey is.
