Description

Die Erfindung betrifft eine Vorrichtung zur Sammlung von Wasser, das bei einer Klimaanlage eines Kraftfahrzeuges als Kondensat anfällt, nach dem Oberbegriff des Anspruchs 1.The invention relates to a device for collecting water, which at an air conditioning system of a motor vehicle as condensate, after Preamble of claim 1.

Bei Klimaanlagen kondensiert der in der Luft enthaltene Wasserdampf am kalten Wärmetauscher zu Wasser. Dieses wird dann üblicherweise zum Boden hin abgeführt.In air conditioning systems, the water vapor contained in the air condenses on cold heat exchanger to water. This then usually becomes Soil led away.

Während der Fahrt ist dies nicht von Bedeutung, da das kondensierte Wasser sauber ist und lediglich eine Benetzung des Bodens aber keinerlei Verschmutzung der Umwelt bewirkt. Nach dem Abstellen des Fahrzeuges, z. B. in der Garage, kann es aber zur Bildung einer unerwünschten Was­ serlache auf dem Boden kommen.This is irrelevant while driving because the condensed Water is clean and only a wetting of the floor but no water Pollution of the environment causes. After parking the vehicle, e.g. B. in the garage, but it can form an undesirable What come on the floor.

Aus der DE 38 21 897 A1 ist eine Vorrichtung gemäß dem Oberbegriff des Anspruchs 1 bekannt, bei der Kondensat, das in einem Kühl-Wärme­ tauscher und in einem Trockner einer Fahrzeug-Klimaanlage anfällt, ei­ nem Vorratsbehälter der Klimaanlage zugeführt wird, um es in der Klima­ anlage wiederverwenden zu können.DE 38 21 897 A1 describes a device according to the preamble of Claim 1 known in the condensate in a cooling heat exchanger and accumulates in a dryer of a vehicle air conditioning system, ei The air conditioning reservoir is fed to it in the climate to be able to reuse the system.

Der Erfindung liegt die Aufgabe zugrunde, das anfallende Kondenswasser anderweitig zu nutzen.The invention has for its object the condensation otherwise used.

Die Lösung dieser Aufgabe erfolgt gemäß der Erfindung durch die Merkmale des Patentanspruchs.This object is achieved according to the invention by the features of the claim.

Damit ist zum einen sichergestellt, daß über einen vorbestimmten Zeit­ raum kein kondensiertes Wasser mehr auf den Boden gelangt, da es ge­ sammelt wird.This ensures on the one hand that over a predetermined time condensed water no longer reaches the floor as it is collected.

Zum anderen dient in vorteilhafter Weise als Vorratsbehälter der ohnehin erforderliche Scheibenwaschbehälter, aus dem die Scheiben des Kraftfahr­ zeuges mit Waschwasser versorgt werden. Üblicherweise wird hierzu eine kleine elektrische Pumpe verwendet, so daß der Vorratsbehälter irgendwo im Kraftfahrzeug untergebracht sein kann, was die Designfreiheit erhöht. Infolge diese Anordnung wird der Waschwasservorrat während der Fahrt laufend ergänzt, so daß sich das übliche Nachfüllen erübrigt. Das nach­ gefüllte Wasser ist sauber und neutral, so daß weder Filter noch Düsen der Scheibenwaschanlage zu verstopfen drohen. Wasserlachen auf dem Boden sind vermieden und damit die irrtümliche Annahme, daß ein Defekt (Undichtigkeit) am Kraftfahrzeug vorliegen könnte.On the other hand, advantageously serves as a storage container anyway required windshield washer tank from which the windows of the motor vehicle be supplied with wash water. Usually a small electric pump used, so the reservoir somewhere can be accommodated in the motor vehicle, which increases the freedom of design. As a result of this arrangement, the wash water supply becomes in motion continually added, so that the usual refilling is unnecessary. That after filled water is clean and neutral, so that neither filters nor nozzles  the windscreen washer system may become clogged. Pool of water the ground are avoided and thus the erroneous assumption that there could be a defect (leak) in the motor vehicle.

In Weiterbildung der Erfindung kann ein Ventil vorgesehen werden, das die Zufuhr von Wasser stoppt, wenn der Vorratsbehälter gefüllt ist, sowie eine Überlaufvorrichtung, die bei geschlossenem Ventil das weiter anfallende Wasser ableitet. Falls dann Waschwasserzusätze, wie Reinigungs- oder Frostschutzmittel, zugesetzt sind, führt diese Anordnung dazu, daß solche Zusatzmittel nicht mit überlaufendem Wasser entweichen können.In a further development of the invention, a valve can be provided that stops the supply of water when the Reservoir is filled, and an overflow device that if the valve is closed, the water that accumulates is drained off. If then wash water additives, such as cleaning or Antifreeze, this arrangement leads to that such additives are not overflowing with water can escape.

Die Erfindung stellt sicher, daß gerade in der heißen und meist trockenen Jahreszeit, bzw. bei entsprechendem Klima, immer genug Scheibenwaschwasser zur Verfügung steht, das dann dringend zur Scheibenreinigung benötigt wird.The invention ensures that just in the hot and mostly dry season, or with the right climate, always enough Windshield washer water is available, which is then urgently needed Window cleaning is needed.

In der Zeichnung ist ein Ausführungsbeispiel der Erfindung in schematischer Weise dargestellt. Die einzige Figur zeigt eine Auffangwanne 1 zur Sammlung von Kondenswasser 2, das von einem nicht dargestellten Wärmetauscher einer Klimaanlage eines Kraftfahrzeuges tropft. Eine Leitung 3 führt das Wasser 2 zu einem Vorratsbehälter 4, der als Scheibenwaschbehälter im Kraftfahrzeug dient. Das Wasser 2 tritt durch eine obere Öffnung 5 in den Behälter 4 ein. Wenn die Scheibenwaschflüssigkeit die Öffnung 5 nahezu errreicht hat, verschließt ein Schwimmerventil 6 die Öffnung 5. Dann kann das Wasser 2a über eine Überlaufleitung 7 abgeleitet werden.In the drawing, an embodiment of the invention is shown in a schematic manner. The single figure shows a sump 1 for collecting condensed water 2 dripping from a heat exchanger (not shown) of an air conditioning system of a motor vehicle. A line 3 leads the water 2 to a storage container 4 , which serves as a windscreen washer container in the motor vehicle. The water 2 enters the container 4 through an upper opening 5 . When the windshield washer fluid has almost reached the opening 5 , a float valve 6 closes the opening 5 . Then the water 2 a can be discharged via an overflow line 7 .

Wenn durch Verbrauch von Scheibenwaschflüssigkeit das Schwimmerventil 6 gesunken ist, ist die Öffnung 5 wieder freigegeben, und weiteres Wasser 2 kann in den Vorratsbehälter 4 einlaufen, bis das Ventil 6 wieder schließt.If the float valve has fallen 6 by consumption of washer fluid, the opening 5 is released again, and further water 2 can enter into the storage vessel 4 until the valve 6 closes again.

Nicht dargestellt sind die üblichen Ausstattungsmerkmale eines Scheibenwaschbehälters, wie Pumpe und Ablaufschlauch zu den Düsen. Das Ventil 6 kann z. B. auch mit einem bekannten Flüssig­ keitsstandanzeiger kombiniert werden; dies ist jedoch nicht dar­ gestellt. Bei entsprechender Fernanzeige kann der Fahrer dann vom Cockpit aus den Füllungsgrad des Vorratsbehälters über­ wachen.The usual features of a windscreen washer reservoir, such as a pump and drain hose to the nozzles, are not shown. The valve 6 can e.g. B. can also be combined with a known liquid level indicator; however, this is not shown. With the appropriate remote display, the driver can then monitor the filling level of the storage container from the cockpit.
