BeschreibungDescription

1. Bezeichnung1. Designation

Vorrichtung zur Verhinderung des Anfrierens und Vereisens von Scheibenwischern an der Frontscheibe von PKW.Device for preventing windscreen wipers from freezing and icing on the windscreen of cars.

2. Problemstellung2. Problem

Regen, Schnee und Eisregen führen dazu, das bei Minustemperaturen die Wischerblätter an der Frontscheibe festfrieren. Es genügt oft nicht, wenn der PKW-Fahrer die angefrorenen Wischergummis von der Scheibe löst, denn nach Fahrtbeginn frieren diese an der kalten Frontscheibe immer wieder an. Sobald der Fahrer dann die Scheibenwischer betätigt, führen Eispartikelchen dazu, dass das Wischergummi nicht sauber und komplett auf der Frontscheibe aufliegt und es kommt zur Schlierenbildung, welche die Sicht des Fahrers besonders bei Fahrten in der Dunkelheit behindert (Lichtreflexe usw.).Rain, snow and sleet cause the wiper blades to freeze to the windscreen at sub-zero temperatures. It is often not enough for the car driver to remove the frozen wiper blades from the windscreen, because once the journey has begun, they keep freezing to the cold windscreen. As soon as the driver then operates the windscreen wipers, ice particles mean that the wiper blades do not lie cleanly and completely on the windscreen and streaks form, which impair the driver's vision, especially when driving in the dark (light reflections, etc.).

Erst wenn das Fahrzeug nach längerer Fahrt komplett erwärmt und aufgeheizt ist, frieren auch die Wischergummis nicht mehr an. Dann erst führt die Betätigung der Scheibenwischer zum gewünschten Ergebnis und zu einer einwandfreien Durchsicht ohne Schlierenbildung.Only when the vehicle has completely warmed up and warmed up after a long journey will the wiper rubbers no longer freeze. Only then will operating the windshield wipers produce the desired result and provide perfect visibility without streaks.

3. Problemlösung3. Problem solving

Eine über Heizdrähte beheizbare Fläche (A), ähnlich der Heckscheibenheizung, wird im unteren Bereich der Frontscheibe eingebaut, und zwar in dem Bereich, in dem sich die Scheibenwischer in Ruhestellung befinden. Somit ist eine Sichtbehinderung des Fahrzeugführers durch Heizdrähte ausgeschlossen.A surface (A) that can be heated using heating wires, similar to the rear window heating, is installed in the lower part of the windscreen, in the area where the windscreen wipers are in the rest position. This means that the driver's view cannot be obstructed by heating wires.

Ergänzt wird diese ,Frontscheibenheizung' durch zwei Luftauslassschlitze (B), welche am oberen Abschluss der Motorhaube angebracht sind, wie in der anliegenden Zeichnung dargestellt. Durch diese Schlitze wird bereits nach relativ kurzer Fahrzeit warme bzw. angewärmte Luft aus dem Motorraum unter die Wischerblätter geleitet, taut dort vorhandene Eispartikel auf und verhindert das ,Wiederanfrieren' der Wischergummis. Gleitzeitig wird die Elastizität des Gummimaterials durch Wärmeeinwirkung deutlich verbessert. Das Einschalten der ,Frontscheibenheizung' als auch das Öffnen der beschriebenen Warmluftauslässe erfolgt automatisch nach Starten des Fahrzeuges, sobald über einen Temperaturfühler (C) eine Temperatur < 0° C gemessen wird.This 'windscreen heating' is supplemented by two air outlet slots (B) which are attached to the top of the bonnet, as shown in the attached drawing. After a relatively short period of driving, warm or heated air from the engine compartment is directed through these slots under the wiper blades, thawing any ice particles present there and preventing the wiper rubbers from 'refreezing'. At the same time, the elasticity of the rubber material is significantly improved by the effect of heat. The 'windscreen heating' and the described warm air outlets are switched on automatically after the vehicle is started as soon as a temperature of < 0° C is measured by a temperature sensor (C).

Die Öffnungen der Luftschlitze sind mit Schiebern abgedeckt, welche bei Erreichen einer noch festzulegenden Temperaturgrenze mittels Wärmefühler die Luftauslässe schließen. Somit wird verhindert, das bei hohen Temperaturen im Motorraum Schäden an Gummiteilen wie Wischergummi, Scheibendichtung o.a. durch die unter die Wischerblätter geleitete Warmluft entstehen.The openings of the air slots are covered with sliders, which use a heat sensor to close the air outlets when a temperature limit (which has yet to be determined) is reached. This prevents damage to rubber parts such as wiper rubber, window seals, etc. caused by the warm air directed under the wiper blades when the engine compartment is at high temperatures.

Durch die Beheizbarkeit bzw. Erwärmung des o.g. Frontscheibenbereichs ergibt für den Fahrzeugführer zum einen eine Annehmlichkeit, da die Eisansammlung an den Wischergummis als auch das Anfrieren der Wischergummis verhindert wird.The heating or warming of the above-mentioned windscreen area provides convenience for the driver, as it prevents ice from accumulating on the wiper rubbers and also prevents the wiper rubbers from freezing.

Zum anderen trägt der kombinierte Einbau von ,Frontscheibenheizung' und Warmluftauslass in hohem Maße dazu bei, die Verkehrssicherheit durch einwandfreie Sicht entscheidend zu verbessern.On the other hand, the combined installation of 'windscreen heating' and warm air outlet contributes significantly to improving road safety by providing perfect visibility.

Komfortabler gestaltet werden kann die Nutzung der oben beschriebenen ,Frontscheibenheizung' noch durch den Einbau einer Zeitschaltuhr. Diese ermöglicht es dem Fahrer, die mit Eispartikelchen besetzten Wischergummis rechtzeitig vor Fahrtbeginn durch Wärmebildung im unteren Bereich der Frontscheibe aufzutauen. Sobald dann die Frontscheibe freigekratzt und von Schnee und Eis befreit ist, ist ein einwandfreier Betrieb der Scheibenwischer ohne Schlierenbildung durch sauber anliegende Wischergummis gewährleistet.The use of the "windscreen heating" described above can be made even more convenient by installing a timer. This allows the driver to defrost the wiper blades covered in ice particles in good time before setting off by generating heat in the lower part of the windscreen. As soon as the windscreen has been scraped free of snow and ice, the wipers will operate perfectly without streaking thanks to the cleanly fitting wiper blades.
