Definitions
- the invention relates to an electric heating element according to the preamble of claim 1.
- Such an electrical heating element is known from DE-B-1 515 030. Any information about the reinforcement strip is missing. Reinforcing wires made of nylon are also mentioned in the document.
- a heating element 1 is shown with an electrical resistance strip 2, which is arranged in a meandering shape.
- the electrical connections are labeled 3 and 4.
- the resistance strip is applied as a layer on at least one film on insulating material 5, the width of which is greater than the width of the resistance strip arrangement.
- the free insulation areas outside the resistor strip assembly are normally used to attach the element to a wall, ceiling, or the like by nailing or otherwise.
- the lateral insulation surfaces are reinforced.
- the reinforcement consists to a certain extent of stretchable textile fabric 6, as a result of which the best possible connection between the insulating films and the reinforcement can be achieved.
- the reinforcement is required to withstand tensile strengths of at least 10 Newtons in each direction for ten seconds.
- this element consists of two arrays of resistance strips 10 and 11, which can be parallel or in series, depending on the installation requirements.
- this element in addition to the outer reinforcements (13), there is also a reinforcement strip 12 or the like in the "side surface" between the two resistance strip arrangements 10 and 11.
- FIG. 3 shows a cross section of the element according to FIG. 1 along the section line 111.
- the resistance strip arrangement denoted by 2
- the resistance strip arrangement is located between two insulation films 5 in the form of a layer arrangement, and the reinforcements 6 are likewise in the form of a layer arrangement between the insulation films 5.
- the reinforcements 6 which are attached in the "nail surface" of the heating element should preferably have a thickness which is greater than the thickness of the resistance strip arrangement in order to avoid undesired pressure on the resistance strips during installation. When nailing the element to a wall or ceiling, the reinforcements absorb all or most of the pressure that would otherwise undesirably affect the resistance strip arrangement.
- Fig. 4 shows schematically a portion of a side surface of a heating element, in which the insulating films are transparent in order to facilitate attachment.
- the reinforcement is of the type of a to some extent stretchable, coarse-mesh textile fabric. In this case, the installers can simply be instructed to hit the nails in the reinforcement surface, or better, if the reinforcement is made of colored material, into the colored surface.
- FIGS. Cross sections of the side surface according to FIG. 4 are shown in FIGS. It can be seen there that the two insulation foils 5 lie against one another and are connected there by the spaces between the horizontal and vertical threads 20 and 21 of the reinforcement, so that the best possible connection between the insulation foils and the reinforcement is achieved.

Description
- Die Erfindung betrifft ein elektrisches Heizelement nach dem Oberbegriff des Patentanspruchs 1.
- Ein derartiges elektrisches Heizelement ist bekannt aus der DE-B-1 515 030. Irgendwelche Angaben über den Verstärkungsstreifen fehlen. Verstärkungsdrähte aus Nylon sind in der Druckschrift ebenfalls erwähnt.
- Es ist die Aufgabe der Erfindung, ein Heizelement der oben genannten Art mit einem speziellen Verstärkungsstreifen anzugeben.
- Die Aufgabe wird wie im Patentanspruch 1 angegeben gelöst. Weiterbildungen ergeben sich aus den Unteransprüchen.
- Die Erfindung wird nun anhand der Zeichnungen beispieslweise näher erläutert. Es zeigen:
- Fig. 1 ein Heizelement gemäß der Erfindung,
- Fig. 2 ein Doppel-Heizelement,
- Fig. 3 einen Querschnitt entlang des Schnittlinie 111 von Fig. 1,
- Fig. 4 einen Teil eines Heizelementes mit einer grobmaschigen Verstärkung,
- Fig. 5 einen Querschnitt durch das Element nach Fig. 4 entlang der Schnittlinie V und
- Fig. 6 einen Querschnitt durch das Element nach Fig. 4 entlang der Schnittlinie VI.
- In Fig. 1 ist ein Heizelement 1 mit einem elektrischen Widerstandsstreifen 2 gezeigt, der mäanderförmig angeordnet ist. Die elektrischen Anschlüsse sind mit 3 und 4 bezeichnet. Der Widerstandsstreifen ist als Schicht auf mindestens eine Folie auf Isoliermaterial 5 aufgebracht, deren Breite größer ist als die Breite der Widerstandsstreiferi-Anordnung.
- Die freien Isolationsflächen außerhalb der Widerstandsstreifen-Anordnung werden normalerweise dazu benutzt, das Element durch Nageln oder auf andere Weise an einer Wand, einer Decke oder dergleichen zu befestigen.
- Die seitlichen Isolationsflächen sind verstärkt. Erfindungsgemäß besteht die Verstärkung aus in gewissem Maße dehnbarem Textilgewebe 6, wodurch sich die beste mögliche Verbindung zwischen den Isolationsfolien und der Verstärkung erzielen läßt. Von der Verstärkung wird gefordert, daß sie in jeder Richtung Reißkräfte von mindestens 10 Newton zehn Sekunden lang aushält.
- Die Fig. 2 zeigt die Anwendung des erfindungsgemäßen Prinzips auf ein sogenanntes Doppel-Heizelement. Wie gezeigt, besteht dieses Element aus zwei Anordnungen von Widerstandsstreifen 10 und 11, welche parallel oder in Reihe geschaitet sein können, je nachdem, wie es die Installation verlangt. In diesem Falle ist zusätzlich zu den äußeren Verstärkungen (13) auch ein Verstärkungsstreifen 12 oder dergleichen in der "Seitenfläche" zwischen den beiden Widerstandsstreifen-Anordnungen 10 und 11 vorhanden.
- Die Fig. 3 zeigt einen Querschnitt des Elements nach Fig. 1 entlang der Schnittlinie 111. Die mit 2 bezeichnete Widerstandsstreifen-Anordnung befindet sich zwischen zwei Isolationsfolien 5 in Form einer Schichtanordnung, und die Verstärkungen 6 befinden sich ebenfalls in Form einer Schichtanordnung zwischen den Isolationsfolien 5. Die Verstärkungen 6, die in der "Nagelfläche" des Heizelements angebracht sind, sollten vorzugsweise eine Dicke haben, die größer ist als die Dicke der Widerstandsstreifen-Anordnung, damit während der Installation ein unerwünschter Druck auf die Widerstandsstreifen vermieden wird. Beim Nageln des Elements an eine Wand oder an eine Decke nehmen die Verstärkungen den ganzen Druck oder den größten Teil davon auf, der ansonsten die Widerstandsstreifen-Anordnung in unerwünschter Weise beeinträchtigen würde.
- Die Fig. 4 zeigt schematisch einen Abschnitt einer Seitenfläche eines Heizelements, bei dem die Isolationsfolien durchsichtig sind, um die Befestigung zu erleichtern. Die Verstärkung ist dabei von der Art eines in gewissem Maße dehnbaren grobmaschigen Textilgewebes. In diesem Falle können die Installationsleute einfach angewiesen werden, die Nägel in der Verstärkungsfläche zu schlagen, oder besser, wenn die Verstärkung aus gefärbtem Material besteht, in die gefärbte Fläche.
- Querschnitte der Seitenfläche nach Fig. 4 sind in den Figuren 5 gezeigt. Man sieht dort, daß die beiden Isolationsfolien 5 durch die Zwischenräume zwischen den horizontalen und vertikalen Fäden 20 und 21 der Verstärkung aneinanderliegen und dort verbunden sind, so daß die bestmögliche Verbindung zwischen den Isolationsfolien und der Verstärkung erreicht wird.
