Abstract
Description
Eisbildung an den Scheibenwischern ist allen Autofahrern ein wohlbekanntes Problem. Dies geschieht sehr oft bei Temperaturen um den Gefrierpunkt zusammen mit Schnee fall. Die Sicht des Fahrers durch die Windschutzscheibe wird erheblich reduziert, die Sicherheit im Straßenverkehr ist in hohem Maße beeinträchtigt.Ice formation on the windshield wipers is a well-known problem for all drivers. This happens very often at temperatures around freezing together with snow case. The driver's view through the windshield is significantly reduced, which Road safety is severely compromised.
Irgendwie jedoch muß das Eis an den Scheibenwischerblättern beseitigt werden. Das Fenster der Fahrertür herunterzukurbeln und von Hand zu versuchen, das Eis wegzu schlagen, ist umständlich und dient nicht unbedingt der Verkehrssicherheit. Auf den nächsten Parkplatz zu fahren, dort anhalten und auszusteigen, um das Eis zu ent fernen, kostet den unter Zeitdruck stehenden Fahrer, insbesondere Lkw-Fahrer, viel Zeit. Keine dieser Methoden sind wirklich erfolgreich, weil man weiß, daß die Wischerblätter innerhalb weniger Fahrkilometer wieder vereist sind.Somehow the ice on the wiper blades has to be removed. The Wind down the driver's door and try to remove the ice by hand beating is cumbersome and does not necessarily serve traffic safety. On the Drive to the next parking lot, stop there and get out to get the ice far away, costs the driver, who is under time pressure, especially truck drivers, a lot Time. None of these methods are really successful because you know that Wiper blades are iced up again within a few kilometers.
Aufgabe des Verfahrens und der Vorrichtung ist es, die Vereisung der Wischerblätter des Scheibenwischers nachhaltig zu verhindern. Gelöst wird diese Aufgabe durch das Verfahren zum Beheizen des Scheibenwischer nach Anspruch 1 und die Vorrichtung nach Anspruch 2. Sinnvolle Ausgestaltungen sind den Unteransprüchen zu entnehmen.The task of the method and the device is to freeze the wiper blades of the windshield wiper to prevent sustainable. This task is solved by the A method of heating the wiper according to claim 1 and the device according to claim 2. Useful embodiments can be found in the subclaims.
Im Schlauchsystem des Kühlwasserkreislaufs eines Fahrzeugs werden auf der Heiß wasserseite Abzweigungen in der Form von T-Stücken montiert, durch welche das erhitzte Kühlwasser des Motors als Heizwasser in den Heizkreislauf des Scheiben wischers eingeleitet und wieder zurückgeführt wird. Es fließt durch Silikonschläuche zum Wischerblatt und dort durch die am Wischerblatt angebrachten Heizrohre. Der Wärmetransport wird durch die am Wischerblatt angebrachten Anbauplatten gesichert. Als bevorzugte Stelle der T-Stücke wird der Bereich der Innenraumheizung des Fahr zeugs angesehen. Dort kann über die vorgesehenen Absperrhähne das Heizsystem für die Scheibenwischer je nach Bedarf zugeschaltet oder abgeschaltet werden. Das Heiß wasser zirkuliert in dem geschlossenen System des Kühlwasserkreislaufs des Fahr zeugmotors. Die Heizleistung errechnet sich mit 1800 Watt. Ein Wasserverlust entsteht nicht im Kühlwassersystem des Fahrzeugs. In the hose system of a vehicle's cooling water circuit, the heat is on water-side branches mounted in the form of T-pieces, through which the heated engine cooling water as heating water in the heating circuit of the windows wiper is initiated and returned. It flows through silicone hoses to the wiper blade and there through the heating pipes attached to the wiper blade. Of the Heat transport is ensured by the mounting plates attached to the wiper blade. The area of the interior heating of the driver is the preferred location of the T-pieces viewed stuff. There, the heating system for the wipers can be switched on or off as required. The hot water circulates in the closed system of the cooling water circuit of the driver tool motor. The heating power is calculated at 1800 watts. There is a loss of water not in the vehicle's cooling water system.
Dieses Verfahren und die Vorrichtung sind eine effektive Lösung zur Verhinderung der Eisbildung auf den Wischerblätter der Scheibenwischer von Fahrzeugen. Die Montage der Vorrichtung ist einfach und kann von jedem Automechaniker installiert werden.This method and device are an effective prevention solution the formation of ice on the wiper blades of vehicle wipers. The Assembly of the device is simple and can be installed by any auto mechanic will.
Ausführungsbeispiele sind in den Figuren dargestellt. Auf die Darstellung des Wischerblatts ist verzichtet worden.Exemplary embodiments are shown in the figures. On the representation of the Wiper blade has been omitted.
Fig. 1 zeigt im oberen Teil die bevorzugte Ausführungsform mit dem u-förmig gebogenen Heizrohr, bei welchem die beiden Schlauchanschlüsse nebeneinander am gleichen Ende des Wischerblatts liegen. Im unteren Teil ist die bevorzugte Aus führungsform dargestellt, welche die Schlauchanschlüsse im Bereich des Lagergelenks des Wischerblatts am Wischerarm aufweisen. Das Heizrohr ist hier etwa omega-förmig ausgebildet. Fig. 1 shows in the upper part the preferred embodiment with the U-shaped heating tube, in which the two hose connections are next to each other at the same end of the wiper blade. In the lower part, the preferred embodiment is shown, which have the hose connections in the area of the bearing joint of the wiper blade on the wiper arm. The heating tube is approximately omega-shaped here.
Fig. 2 zeigt den Anschluß des Heizsystems an das Kühlwassersystem des Fahrzeugs im Bereich der Wasserpumpe des Motors. Fig. 2 shows the connection of the heating system to the cooling water system of the vehicle in the area of the water pump of the engine.
