Abstract

The application relates to a water drain nozzle, in particular for heating or air conditioning systems of motor vehicles. In order to achieve an especially simple construction of a water drain nozzle of this kind, it is provided according to the invention that its entire cross-section is filled with an open-celled foam plastic, at least over a part of its height.

Description

"Wasserablauftülle, insbesondere für Heizungs-"Water drainage nozzle, especially for heating

oder Klimaanlagen von Kraftwagen" Die Erfindung betrifft eine Wasserablauftülle, insbesondere für Heizungs- oder Klimaanlagen von Kraftwagen. or air conditioning systems of motor vehicles "The invention relates to a water drainage spout, in particular for heating or air conditioning systems in motor vehicles.

Derartige Ablauftüllen wurden bisher mit Gummiventilen oder Lippenverschlüssen versehen, so daß sich insgesamt eine Konstruktion ergab, zu deren Herstellung relativ aufwendige Werkzeuge erforderlich waren.Such drain spouts were previously with rubber valves or lip seals provided, so that overall a construction resulted, relative to the production thereof expensive tools were required.

Der vorliegenden Erfindung lag die Aufgabe zugrunde, dies zu vermeiden und eine Wasserablauftülle zu schaffen, die auf einfachste Weise preiswert herstellbar ist.The present invention was based on the object of avoiding this and to create a water drainage spout that can be manufactured inexpensively in the simplest way is.

Dies wird bei einer gattungsgemäßen Wasserablauftülle erfindungsgemäß dadurch erreicht, daß zumindest auf einem Teil ihrer Höhe ihr gesamter Querschnitt durch einen offenzelligen Schaumkunststoff ausgefüllt ist.This is according to the invention in the case of a generic water drainage spout achieved in that at least part of their height their entire cross-section is filled with an open-cell foam plastic.

In besonders vorteilhafter Ausgestaltung der Erfindung ist weiter vorgesehen, daß die Wasserablauftülle als Formteil mit einem Kern aus offenzelligem Schaumkunststoff mit einer Außenhaut aus geschlossenzelligem Kunststoff ausgebildet ist.In a particularly advantageous embodiment of the invention is further provided that the water drainage spout as a molded part with a core made of open-celled Foam plastic formed with an outer skin made of closed-cell plastic is.

Der Gegenstand der Erfindung soll im folgenden anhand eines in der Zeichnung in einem Vertikalschnitt dargestellten Ausführungsbeispiels näher erläutert werden.The object of the invention is to be based on one in the Drawing explained in more detail in a vertical section illustrated embodiment will.

Die in der Zeichnung dargestellte Wasserablauftülle 1 weist eine Außenhaut 1a aus geschlossenzelligem Kunststoff und einem Kern 1b aus offenzelligem Schaumkunststoff auf.The water drainage spout 1 shown in the drawing has an outer skin 1a made of closed-cell plastic and a core 1b made of open-cell foam plastic on.

Die Wasserablauftülle 1 ist über ein Schlauchband 2 im Bodenbereich 3 einer nicht näher dargestellten Heizungs- oder Klimaanlage eines Kraftwagens befestigt und in ihrem mittleren Bereich durch eine Öffnung einer Blechwand 4 des Fahrzeugs dichtend hindurchgeführt. Dabei wird eine radiale Einschnürung 5 gebildet, in deren Bereich die Wasserablauftülle 1 durch elastische Rückstellwirkung ihres Schaumkernes gegen die Innenwandung der Öffnung gepreßt wird.The water drainage spout 1 is on a hose band 2 in the floor area 3 attached to a heating or air conditioning system, not shown, of a motor vehicle and in its central area through an opening in a sheet metal wall 4 of the vehicle sealingly passed through. A radial constriction 5 is formed in which Area of the water drainage spout 1 through the elastic restoring effect of its foam core is pressed against the inner wall of the opening.

Die erfindungsgemäße Wasserablauftülle bringt eine Reihe wesentlicher Vorteile mit sich.The water drainage spout according to the invention brings a number of essentials Advantages with itself.

So wird durch das durch den Schaumkern gebildete labyrinthartige Kanalsystem der Strömungswiderstand für Luft so stark erhöht, daß nur ein sehr geringer Luftaustausch zwischen vorhandenen Hoch-und Niederdruckgebieten einer Heiz- bzw. Klimaanlage und deren Umgebung auftreten kann.This is how through the labyrinthine channel system formed by the foam core the flow resistance for air increases so much that only a very small exchange of air between existing high and low pressure areas of a heating or air conditioning system and whose environment can occur.

Außerdem wirkt der Schaum schalldämpfend und verhindert das Eindringen von Insekten oder dgl. in die Klimaanlage.In addition, the foam has a sound-absorbing effect and prevents penetration of insects or the like. In the air conditioner.
