Abstract

A device for heating up the washing water for windows of motor vehicles with a water-cooled engine and a heat exchanger (I) in an airstream, heated cooling water flowing through the heat exchanger (I), contains a washing water container (II) which is attached to the side of the heat exchanger (I) outside the airstream which flows through the heat exchanger and is matched to the shape of the heat exchanger. In order to provide a more reliable means of avoiding the washing water freezing, even without using an antifreeze additive, the radiator (I) for the passenger compartment of the vehicle, which radiator (I) is arranged in a fresh air feed channel, is used as heat exchanger. <IMAGE>

Description

Die Erfindung bezieht sich auf eine Einrichtung zum Erwärmen des Waschwassers für Scheiben von Kraftfahrzeugen mit wassergekühltem Motor und einem vom erwärmten Kühlwasser durchströmten Wärmetauscher in einem Luftstrom, mit einem Waschwasserbehälter, der seitlich am Wärmetauscher außerhalb des den Wärmetauscher durchströmenden Luftstroms angebracht und der Form des Wärmetauschers angepaßt ist.The invention relates to a device for heating of the washing water for windows of motor vehicles with a water-cooled motor and one from the heated cooling water flowed through heat exchanger in an air flow, with a wash water tank on the side of the heat exchanger outside of the flow through the heat exchanger Airflow attached and the shape of the heat exchanger is adjusted.

Eine derartige Einrichtung ist aus der DE-PS 31 00 438 oder der GB-OS 21 16 921 bekannt. Bei dieser bekannten Einrichtung ist der Waschwasserbehälter an dem im Motorraum angeordneten Kühler angebracht. Auf diese Weise kann die Abwärme des Kühlers das Waschwasser im Waschwasserbehälter erwärmen, so daß es im Winter, falls es eingefroren ist, nach Erwärmung des Motors rasch auftaut bzw. während der Fahrt nicht einfriert und umweltschädliches Frostschutzmittel entfallen kann. Such a device is from DE-PS 31 00 438 or GB-OS 21 16 921 known. In this known The device is the wash water tank on the in the engine compartment arranged cooler attached. In this way the waste heat from the cooler can cause the wash water in the wash water tank heat it up in winter in case it frozen, thawed quickly after the engine warmed up or not freeze while driving and environmentally harmful Antifreeze can be omitted.  

Die Anbringung des Waschwasserbehälters am Kühler verhindert jedoch nicht das Einfrieren des Waschwassers bei stehendem Motor, wenn das Fahrzeug bei Temperaturen unter dem Gefrierpunkt im Freien steht, oder das Einfrieren des Waschwassers bei Außentemperaturen unter dem Gefrierpunkt, bevor der Motor nach dem Anlassen hinreichend erwärmt ist, falls das Waschwasser nicht eingefroren war, weil das Kraftfahrzeug in einem wärmeren Raum abgestellt war.The attachment of the wash water tank to the radiator prevented however not freezing the wash water stationary engine when the vehicle is at temperatures below freezing or freezing the washing water at outside temperatures below freezing, before the engine is sufficient after starting is heated if the wash water is not frozen was because the car was parked in a warmer room was.

Der Erfindung liegt die Aufgabe zugrunde, eine Einrichtung der gattungsgemäßen Art anzugeben, bei der das Einfrieren des Waschwassers auch ohne einen Frostschutzmittelzusatz zuverlässiger vermieden ist.The invention has for its object a device of the generic type, in which the freezing of the washing water even without an anti-freeze additive is avoided more reliably.

Erfindungsgemäß ist diese Aufgabe dadurch gelöst, daß der Wärmetauscher der in einem Frischluftzufuhrkanal angeordnete Heizkörper für den Fahrzeuginnenraum ist.According to the invention this object is achieved in that the heat exchanger in a fresh air supply duct arranged radiator for the vehicle interior is.

Diese Anbringung des Waschwasserbehälters hat den Vorteil, daß der Waschwasserbehälter sowohl bei abgestelltem Motor als auch während der Fahrt besser vor niedrigeren Außentemperaturen geschützt ist. So bewirkt der Frischluftzufuhrkanal zum einen eine zusätzliche Isolation, und zum anderen steht er mit dem auch bei abgestelltem Motor in der Regel wärmeren Innenraum des Kraftfahrzeugs in Verbindung. Sodann wird der Waschwasserbehälter in aller Regel nicht vor Erwärmung des Motors bzw. des Kühlwassers durch eine kalte Luftströmung (Kühlluft oder Fahrtwind) beaufschlagt, weil bei niedrigen Außentemperaturen die Frischluftzufuhr in der Regel so lange unterbunden wird, bis sich der Motor bzw. das Kühlwasser und damit der Heizkörper erwärmt hat. Die Gefahr des Einfrierens des Waschwassers vor dem Warmlaufen des Motors ist daher äußerst gering. Ein weiterer Vorteil besteht darin, daß durch die Unterbringung des Waschwasserbehälters außerhalb des Motorraums ein zusätzlicher Freiraum in dem zumeist ohnehin knapp bemessenen Motorraum zur Verfügung steht.This attachment of the wash water tank has the advantage that the wash water tank both when turned off Engine as well as while driving better before lower Outside temperature is protected. This is how the fresh air supply duct works on the one hand, additional insulation, and on the other hand he stands with the one off Engine usually warmer interior of the motor vehicle in connection. Then the wash water tank is in generally not before the engine or the cooling water heats up by a cold air flow (cooling air or Headwind) because of low outside temperatures the supply of fresh air is usually prevented for as long until the engine or the cooling water and so that the radiator has warmed up. The risk of freezing of the wash water before the engine warms up  therefore extremely low. Another advantage is that by housing the wash water tank additional free space outside the engine compartment the engine compartment, which is usually already tight stands.

Die Erfindung wird nachstehend anhand der Zeichnung eines bevorzugten Ausführungsbeispiels näher beschrieben. Es zeigtThe invention is described below with the aid of a drawing preferred embodiment described in more detail. It shows

Fig. 3 eine Draufsicht auf Waschwasserbehälter und Heizkörper. Fig. 3 is a plan view of the washing water tank and radiator.

Bei dem in der Zeichnung dargestellten Ausführungsbeispiel ist der in einem Frischluftkanal eines Kraftfahrzeugs liegende, vom erwärmten Kühlwasser durchströmte Heizkörper I von einem in der Draufsicht etwa U-förmigen Waschwasserbehälter II mit einem Wassereinfüllstutzen III und einem Pumpenanschlußloch V seitlich anliegend umgeben. Der Waschwasserbehälter ist mithin der Form des Heizkörpers I so angepaßt, daß er seitlich an ihm angebracht werden kann, wobei er jedoch von dessen Wasserkreislauf getrennt ist. Die seitliche Anbringung des Waschwasserbehälters II am Heizkörper I stellt sicher, daß der Gebläseventilator weiterhin ungehindert Frischluft oder bei eingeschalteter Heizung und erwärmtem Motor die Warmluft, die dann den Heizkörper I durchströmt, in den Innenraum des Kraftfahrzeugs blasen kann.In the embodiment shown in the drawing, the radiator I lying in a fresh air duct of a motor vehicle and through which heated cooling water flows is surrounded by a wash water tank II with a water filler neck III and a pump connection hole V which is approximately U-shaped in plan view. The wash water tank is therefore adapted to the shape of the radiator I so that it can be attached to it laterally, although it is separate from its water cycle. The lateral attachment of the washing water tank II to the radiator I ensures that the blower fan can continue to blow unhindered fresh air or, when the heater is switched on and the engine is heated, the warm air which then flows through the radiator I into the interior of the motor vehicle.

Mit IV sind die Kühlwasseranschlüsse des Heizkörpers I bezeichnet.With IV the cooling water connections of the radiator I are designated.
