Description
Die Erfindung bezieht sich auf die Wasserversorgung insbesondere einer Schei benwaschanlage für Kraftfahrzeuge, die in der DE 198 20 220 beschrieben und dargestellt ist.The invention relates to the water supply in particular a Schei Benwaschanlage for motor vehicles, which are described in DE 198 20 220 and is shown.
Die Wasserversorgung für eine Scheibenwaschanlage stellt in den gemäßigten Klimazonen der Erde in der Regel kein Problem dar, da hier genügend Nieder schläge fallen, so daß überall Wasser zum Ergänzen des Vorrats im Vorratsbehäl ter der Scheibenwaschanlage erhältlich ist.The water supply for a windshield washer is in the moderate Earth's climate zones are generally not a problem, as there is enough low here blows fall, so that water everywhere to replenish the supply in the storage container the windscreen washer is available.
In wasserarmen Gebieten, insbesondere in Wüstenzonen, kann dagegen die Wasser versorgung zum Problem werden, vielleicht weniger im geschlossenen Wasser kreislauf des Motorkühlers als bei der Scheibenwaschanlage, die dafür zu sor gen hat, daß z. B. durch Sandstaub verschmutzte Scheiben wieder durchsichtig klar werden. Da ein "trockenes" Betätigen der Scheibenwischer sowohl diese selbst als auch die Glasscheibe beschädigen würde, ist das Verwenden von Was ser zum Reinigen zwingend erforderlich.In poor areas, especially in desert zones, the water can supply become a problem, perhaps less in closed water circuit of the engine cooler than in the windscreen washer system, which is responsible for this gen has that z. B. discs soiled by sand dust again transparent get clear. Because a "dry" actuation of the wipers both these itself as well as damaging the glass pane is using what absolutely necessary for cleaning.
Bereits in der DE 41 01 820 A1 sowie in der DE 43 16 345 A1 wurden Sy steme zum Sammeln von Regenwasser in einer Wasserrinne und dessen Wei terleiten über ein Filter bzw. ein Sieb in einen zwischengeschalteten Auffangbehälter bzw. direkt in den Wassersammelbahälter einer Scheiben waschanlage beschrieben und dargestellt. Auch in der DE 198 20 220 wur de eine bauliche Ergänzung beschrieben, die die Wasserverluste beim Be tätigen der Scheibenwaschanlage dadurch verringert, daß ein Teil der Waschflüssigkeit wieder aufgefangen und nach einer Reinigung dem Vor ratsbehälter zugeführt wird. Wenn auch auf diese Weise an Waschwasser gespart wird, kann der vorhandene Wasservorrat so nur gestreckt werden, so daß er zu irgendeinem späteren Zeitpunkt dennoch ergänzt werden muß.Sy. Have already been described in DE 41 01 820 A1 and in DE 43 16 345 A1 systems for collecting rainwater in a water channel and its white pass through a filter or a sieve into an intermediate one Collection container or directly into the water collection container of a pane car wash described and shown. Also in DE 198 20 220 was de described a structural addition that reduces the water losses in loading operate the windshield washer reduces that part of the Washing liquid collected again and after cleaning the previous one advice container is fed. Albeit this way to wash water is saved, the existing water supply can only be stretched, so that it still has to be added at some later point in time.
Es ist daher die Aufgabe der Erfindung, Wege aufzuzeigen, um das beim Scheiben reinigen in wasserarmen Gebieten verbrauchte Wasser zu ersetzen.It is therefore the object of the invention to show ways to do this when slicing clean to replace used water in arid areas.
Zur Lösung dieser Aufgabe werden mehrere Verfahren vorgeschlagen, die sowohl einzeln als auch in Kombination angewendet werden können:To solve this problem, several methods are proposed, both can be used individually or in combination:
In Wüstenregionen ist in den Sommermonaten eine sehr hohe, relative Luft feuchtigkeit von 70% und mehr vorhanden (siehe z. B. DE 195 04 833). Da sich bei größeren Temperaturunterschieden das in der Luft enthaltene Wasser stets an der kältesten Stelle absetzt, würde sich in einer Klimaanlage eines Fahrzeugs bei einem Luftdurchsatz von 1 m3 und einer Luftfeuchtigkeit von 90% (in der Nacht die Regel) bei einer Außentemperatur von 50°C und einer Innen temperatur im Fahrzeug von 20°C ca 25 g Wasser abscheiden, das in einem Be hälter gesammelt und in zeitlichen Abständen dem Vorratsbehälter der Scheiben waschanlage zugeführt wird. Die konstruktive Ausbildung einer derartigen Maß nahme ist in DE 41 10 081 und DE 195 48 166 angesprochen.In desert regions there is a very high relative humidity of 70% and more in the summer months (see e.g. DE 195 04 833). Since the water contained in the air always settles at the coldest point with larger temperature differences, an air conditioning system of a vehicle would have an air flow rate of 1 m 3 and a humidity of 90% (the rule at night) at an outside temperature of 50 Separate approx. 25 g of water, which is collected in a container and fed to the storage unit for the windscreen washer at regular intervals. The constructive design of such a measure is addressed in DE 41 10 081 and DE 195 48 166.
Es ist bekannt, daß das einen geregelten Katalysator eines Kraftfahrzeugs ver lassende Gemisch zum Teil aus Wasser besteht, das im Bereich des Auspuffs flüssig ist. Es gilt, dieses Wasser aus dem Gemisch abzuscheiden und dem Vor ratsbehälter der Scheibenwaschanlage in zeitlichen Abständen zuzuführen. Für eine bauliche Ausgestaltung des Wasserabscheiders können z. B. Konstruktions- Ideen aus DE 29 04 830, DE 39 33 484 und DE 40 35 149 dienen.It is known that ver a regulated catalyst of a motor vehicle letting mixture partly consists of water that is in the area of the exhaust is liquid. It is important to separate this water from the mixture and the previous one Feed the windscreen washer container at regular intervals. For a structural design of the water separator can, for. B. Construction Ideas from DE 29 04 830, DE 39 33 484 and DE 40 35 149 serve.
Es ist bekannt, daß alternde Bremsflüssigkeit über die zugeführte Luft immer mehr Wasser aufnimmt, was zu damit verbundenen Gefahren, Sicherheitsrisiken, Kosten und nicht zuletzt zu ökologischen Nachteilen führt (siehe Zusammenfas sung der DE 40 22 930). Es besteht deshalb die Möglichkeit, Wasser auszuschei den, sei es durch Kühlung der zugeführten Luft, sei es durch Filtern der Bremsflüssigkeit aufgrund z. B. des unterschiedlichen, spezifischen Gewichtes von Bremsöl und Wasser. Dieses Wasser wird dem Vorratsbehälter der Scheiben waschanlage in zeitlichen Abständen zugeführt.It is known that aging brake fluid always flows through the supplied air absorbs more water, which leads to associated dangers, safety risks, Costs and last but not least leads to ecological disadvantages (see summary solution of DE 40 22 930). It is therefore possible to dispense water that, either by cooling the supplied air or by filtering the Brake fluid due to e.g. B. the different, specific weight of brake oil and water. This water becomes the storage container of the slices washing system fed at intervals.
Bei der Wahl, welche der vorstehend angegebenen Möglichkeiten, Wasser zum Nach füllen des Vorratsbehälters der Scheibenwaschanlage zu erhalten, vorgesehen wird, ist zu bedenken, daß eine Klimaanlage nicht in jedem Kraftfahrzeug vorhan den ist, während geregelte Katalysatoren wohl bald in keinem PKW fehlen werden und Bremsanlagen eine technische Selbstverständlichkeit sind. Das Zuführen des Wassers aus dem jeweiligen Sammelbehälter in den Vorratsbehälter der Scheiben waschanlage kann sowohl manuell bei Bedarf als auch automatisch geregelt in zeit lichen Abständen aufgrund von festgelegten Werten, wie etwa der Wasserstand im Vorratsbehälter der Scheibenwaschanlage, erfolgen. Es ist selbstverständlich, daß ein Wasserüberlauf an dem jeweiligen Sammelbehälter und/oder am Vorratsbehälter der Scheibenwaschanlage vorgesehen wird. Auch dürfte es zweckmäßig sein, eine Fil tereinrichtung zwischen Sammelbehälter und Vorratsbehälter vorzusehen, um Ver schmutzungen des Waschwassers im Vorratsbehälter zu vermeiden. When choosing which of the above options, water for night to fill the reservoir of the windscreen washer , it should be borne in mind that air conditioning is not present in every motor vehicle that is, while regulated catalytic converters will soon not be missing in any car and braking systems are a matter of course. Feeding the Water from the respective collection container into the storage container of the discs car wash can be controlled both manually as required and automatically in time distances based on specified values, such as the water level in the Washer reservoir. It goes without saying that a water overflow on the respective collecting container and / or on the storage container the windscreen washer is provided. It should also be useful to have a fil tereinrichtung between the container and reservoir to provide Ver Avoid contamination of the washing water in the storage tank.
Es soll nicht ausgeschlossen werden, daß das gesammelte Wasser auch für ande re Zwecke verwendet werden kann als zum Ergänzen des Wassers im Vorratsbehäl ter der Scheibenwaschanlage, insbesondere, wenn dieser Vorratsbehälter ge füllt ist. Hierfür kann ein gesonderter Behälter vorgesehen werden - sei es im Gepäckraum des Fahrzeugs, sei es unterhalb des Chassis oder wo immer Platz hierfür erübrigt werden kann -, in den das während der Fahrt gesammelte Was ser dann geleitet wird. Auch diese Einrichtung kann nach Bedarf manuell und/ oder automatisch geregelt betrieben werden.It should not be excluded that the collected water also for others re purposes can be used as to replenish the water in the reservoir ter the windscreen washer, especially if this reservoir ge is filling. A separate container can be provided for this - be it in the luggage compartment of the vehicle, be it under the chassis or wherever there is space can be dispensed with - in which the what collected during the journey he is then directed. This device can also be manually and / or operated automatically controlled.
