Abstract

An electrical surface-heating element (1) comprises a knitted base (2) having at least one electrically conductive heating wire (3,4,5,6) linearly incorporated into the base. Preferably the incorporation is by means of a double knitted arrangement.

Description

Die Erfindung betrifft ein elektrisches Flächenheizelement gemäß dem Oberbegriff des Anspruches 1.The invention relates to an electric surface heating element according to the preamble of claim 1.

Ein derartiges Flächenheizelement ist aus dem DE-U 92 13 884 bekannt.Such a surface heating element is known from DE-U 92 13 884.

Bei diesem bekannten Heizelement werden die Heizleiter und die Anschlussleitungen in einen aus gestrickter Maschenware bestehenden Basiskörper miteingestrickt.In this known heating element, the heating conductors and the connection lines are mitegestick in a base body made of knitted fabric.

Aus der DE 41 36 425 C ist ein Flächenheizelement bekannt, bei dem Heizleiter als Schussfaden sinusförmig über Maschenfäden eines gewirkten Grundmaterials verlaufen und zumindestens an den Maxima der Amplituden in die Maschen des textilen Grundmaterials eingebunden sind.From DE 41 36 425 C a surface heating element is known in the heating conductor run as a weft sinusoidal over the mesh threads of a knitted base material and are integrated at least at the maxima of the amplitudes in the mesh of the textile base material.

Aus der DE 40 20 580 A1 ist schließlich ein elektrisches Flächenheizelement bekannt, das aus netzartiger Maschenware mit Heizleitern besteht, an deren Enden Kontaktleiter angeschlossen sind. Die Heizleiter sind hierbei in den Maschenverbund der textilen Maschenware derart fest eingebunden, dass sie schlingen-, wellen- oder mäanderförmig verlaufen.From DE 40 20 580 A1 finally an electric surface heating element is known, which consists of reticulated knitwear with heating conductors, at the ends of contact conductors are connected. The heating conductors are in this case so firmly integrated into the mesh composite of the textile knitwear that they run loop, wave or meandering.

Ferner sind Heizelemente bekannt, bei denen die Heizleiter und die Anschlussleitungen aufgeklebt oder eingewirkt sind. Allen diesen Typen ist gemeinsam, dass die einzelnen Heizelemente in Form und Größe an den Verwendungszweck angepasst sind.Furthermore, heating elements are known in which the heating conductors and the connection lines are glued or acted on. All these types have in common that the individual heating elements are adapted in shape and size to the intended use.

Hieraus ergeben sich eine Reihe von Nachteilen:This results in a number of disadvantages:

Die bekannten Flächenheizelemente werden auf Flachstrick- oder Cotton-Maschinen hergestellt und können dementsprechend nur für einen bestimmten Anwendungszweck, wie beispielsweise eine spezielle Sitzkontur eines Fahrzeugsitzes, verwendet werden.The known surface heating elements are manufactured on flat knit or cotton machines and can accordingly only be used for a particular application, such as a specific seat contour of a vehicle seat.

Beim Verstricken des leitenden Fadens ergibt sich bei der Maschenbildung eine hohe Bruchgefahr, da die elektrisch leitfähigen Fäden, die als Heizleiter in den Basiskörper des Flächenheizelements eingearbeitet werden müssen, als Strickmaterial ungeeignet sind. Die Herstellung des Heizelementes ist insgesamt aufwendig und daher langsam und teuer.When knitting the conductive thread results in the formation of stitches a high risk of breakage, since the electrically conductive threads that must be incorporated as a heating element in the base body of the surface heating, are unsuitable as knit material. The production of the heating element is a total of consuming and therefore slow and expensive.

Die erzielte Leistung ist durch die Maschenbildung beim Verstricken unbefriedigend, da sich eine Verlängerung des Leitungsweges beim Einstricken des Heizleiters und damit eine Erhöhung des elektrischen Widerstandes ergibt. Dadurch ergibt sich ein Verlust an elektrischer Energie, der durch eine hohe elektrische Spannung ausgeglichen werden muss, um eine schnelle und ausreichende Wärmeentwicklung zu erreichen.The performance achieved is unsatisfactory due to the stitch formation during knitting, since there is an extension of the conduction path when knitting the heating conductor and thus an increase in the electrical resistance. This results in a loss of electrical energy, which must be compensated by a high electrical voltage in order to achieve a rapid and sufficient heat development.

Schließlich geht durch die beim Herstellungsprozess vorausbestimmten elektrischen Anschlüsse, die entweder eingestrickt oder aufgeklebt sind, Flexibilität bei der Herstellung der Flächenheizelementes verloren.Finally, by the predetermined in the manufacturing process electrical connections that are either knitted or glued, lost flexibility in the production of surface heating element.

Es ist daher Aufgabe der vorliegenden Erfindung, ein elektrisches Flächenheizelement der im Oberbegriff des Anspruches 1 angegebenen Gattung zu schaffen, das eine hohe Heizleistung selbst beim Anlegen niedriger Spannungen, wie beispielsweise in Kraftfahrzeugen zur Verfügung stehenden Spannungen von etwa 12 Volt, möglich macht und dabei einfach und preisgünstig herstellbar ist.It is therefore an object of the present invention to provide an electric surface heating of the type specified in the preamble of claim 1, which makes a high heating power even when low voltages, such as in motor vehicles available voltages of about 12 volts, possible and easy and inexpensive to produce.

Die Lösung dieser Aufgabe erfolgt durch die Merkmale des Anspruches 1.The solution of this object is achieved by the features of claim 1.

Das elektrische Flächenheizelement gemäß der vorliegenden Erfindung zeichnet sich dadurch aus, dass der bzw. die Heizleiter geradlinig in den gestrickten Basiskörper eingelegt werden können. Die Herstellung des erfindungsgemäßen Flächenheizelementes kann auf Rundstrickmaschinen mit einer Breite von 180 cm erfolgen. Aus diesen gestrickten Bahnen mit einer Länge von ca. 50 m pro Stoffrolle können die einzelnen Heizelemente je nach Bedarf zugeschnitten oder gestanzt werden. Die Heizleistung ist bei gleicher Stoffbreite auf der gesamten Stofflänge gleich.The electric surface heating element according to the present invention is characterized in that the heating conductor (s) can be inserted in a straight line into the knitted base body. The surface heating element according to the invention can be produced on circular knitting machines with a width of 180 cm. From these knitted webs with a length of about 50 m per fabric roll, the individual heating elements can be cut or punched as needed. The heat output is the same for the same fabric width on the entire fabric length.

Dadurch ist es möglich, eine günstig herzustellende Meterware zu produzieren, die sehr schnell Wärme erzeugen kann, wobei sogar die Verwendung einer normalen Autobatterie mit 12 Volt bereits ausreichend ist.This makes it possible to produce a cheap manufactured by the meter, which can generate heat very quickly, even the use of a normal car battery with 12 volts is already sufficient.

Die Herstellung auf Rundstrickmaschinen ergibt besonders günstige Herstellungsbedingungen und es ist möglich, die Heizleiter in einem zwei- oder dreidimensionalen Gestrick fest einzubinden. Hierzu ist folgendes erläuternd zu sagen, dass jedes Gestrick im Grunde genommen drei Dimensionen (Länge, Breite, Höhe oder Dicke) aufweist. Durch den Einsatz von Jacquard-Maschinen, die eine Fontur mit mechanisch oder elektronisch auswählbaren Nadeln haben, ist es möglich, Maschenanhäufungen mit verschiedenartigen Konturen herzustellen. Dabei wird die Ober- oder Schauseite des Stoffes an bestimmten Stellen erhaben. In diesem Falle spricht man von einer dritten Dimension.The production on circular knitting machines results in particularly favorable production conditions and it is possible to firmly integrate the heating conductors in a two- or three-dimensional knitted fabric. For this purpose, the following explanatory to say that each knit has basically three dimensions (length, width, height or thickness). By using jacquard machines that have a fontur with mechanically or electronically selectable needles, it is possible to produce mesh accumulations with various contours. The top or side of the fabric is raised at certain points. In this case one speaks of a third dimension.

Die Unteransprüche haben vorteilhafte Weiterbildungen der Erfindung zum Inhalt.The dependent claims have advantageous developments of the invention to the content.

Vorzugsweise werden die Heizleiter im Basiskörper durch ein Doppelgestrick fest eingebunden. Hierzu wird der elektrisch heizbare Stoff mit zwei Fonturen (Nadelbahnen) hergestellt. Hierbei ist eine Nadelreihe am Umfang eines vertikalen Zylinders und eine dazu senkrechte Nadelreihe am Umfang einer horizontalen Scheibe angeordnet. Bevor die Maschen der einen Fontur mit den Maschen der anderen Fontur vermascht werden, wird der elektrisch leitende Faden dazwischen eingelegt und ist somit fest eingebunden. Diesen nicht mitvermaschten und nur eingelegten Faden bezeichnet man auch als Füllfaden.Preferably, the heating conductors are firmly bound in the base body by a double knit. For this purpose, the electrically heatable fabric with two fonts (needle tracks) is produced. Here is a row of needles on the circumference of a vertical Cylinder and a perpendicular row of pins arranged on the circumference of a horizontal disc. Before the stitches of one fontur are meshed with the stitches of the other fontur, the electrically conductive thread is inserted between them and is thus firmly integrated. This not mitvermaschten and only inlaid thread is also referred to as filler.

Ferner ist es möglich, eine Mehrzahl von Heizleitern, insbesondere parallel zueinander, in den Basiskörper zu integrieren. Durch eine Modifizierung des Anschlusses können hierbei Einzelheizleiter so angeschlossen werden, dass eine Stufenheizung möglich ist. Sofern einzelne Segmente nicht beheizt werden sollen, können diese entweder nicht angeschlossen oder nicht mit Strom versorgt werden.Furthermore, it is possible to integrate a plurality of heating conductors, in particular parallel to one another, into the base body. By modifying the connection, individual heating conductors can be connected in such a way that stage heating is possible. If individual segments are not to be heated, they can either not be connected or can not be supplied with power.

Einzelne Heizleiter können auch für Temperaturfühler, Belegungserkennungssensoren oder Ähnliches benutzt werden.Individual heating conductors can also be used for temperature sensors, occupancy detection sensors or similar.

Die Herstellung des Stoffes kann zwei- oder dreidimensional (z.B. als Reliefstruktur) erfolgen. Da der Anschluss an jeder beliebigen Stelle des Heizelementes gemacht werden kann und das Gestrick nach allen Seiten dehnfähig ist, kann sich das erfindungsgemäße Flächenheizelement allen Formen und Dimensionen anpassen.The preparation of the substance can take place in two or three dimensions (for example as a relief structure). Since the connection can be made at any point of the heating element and the fabric is extensible on all sides, the surface heating element according to the invention can adapt to all shapes and dimensions.

Durch den Einsatz entsprechend hochwertiger Materialien kann aus dem Stoff ein Sitzbezugstoff mit integrierter Sitzheizung hergestellt werden.Through the use of high-quality materials can be made from the fabric a seat cover fabric with integrated seat heating.

Wie bereits erläutert, ist durch die parallele und geradlinige Einlegung der Heizleiter in den Basisstoff eine hohe Energieausnutzung möglich, wobei bereits niedrige Stromspannungen zur notwendigen Energiezufuhr ausreichen.As already explained, a high energy utilization is possible by the parallel and rectilinear insertion of the heating element in the base material, even low current voltages are sufficient for the necessary energy supply.

Das Flächenheizelement 1 weist einen gestrickten Basiskörper 2 auf, in den im Beispielsfalle vier elektrisch leitfähige Heizleiter 3, 4, 5, 6 eingelegt sind. Vom Prinzip her ist es möglich, lediglich einen derartigen Heizleiter in den Basiskörper einzulegen oder auch eine beliebig andere Anzahl von Heizleitern, was vom jeweiligen Anwendungszweck abhängt.The surface heating element 1 has a knitted base body 2, in which four electrically conductive heating conductors 3, 4, 5, 6 are inserted in the example. In principle, it is possible to insert only such a heat conductor in the base body or any other number of heating conductors, which depends on the particular application.

Fig. 1 verdeutlicht hierbei, dass durch die geradlinige Einlegung der Heizleiter 3 bis 6 deren Länge zwischen elektrischen Anschlussleitungen 9 und 10 minimierbar ist, was eine Minimierung des elektrischen Widerstandes und damit eine Maximierung der Energieausnutzung möglich macht.Fig. 1 illustrates this that can be minimized by the straight insertion of the heating 3 to 6 whose length between electrical leads 9 and 10, which makes it possible to minimize the electrical resistance and thus maximizing the energy utilization.

Die Heizleiter 3 bis 6 sind jeweils an ihren freien Enden an die elektrischen Anschlüsse 9 und 10 angeschlossen, was durch die freien Enden 7 und 8 des Heizleiters 3 repräsentativ für alle Heizleiter 3 bis 6 dargestellt ist.The heating conductors 3 to 6 are each connected at their free ends to the electrical connections 9 and 10, which is represented by the free ends 7 and 8 of the heating element 3 representative of all heating conductors 3 to 6.

Aus Fig. 2 ergibt sich der Fadenverlauf des elektrischen Flächenheizelementes 1, wobei sich erschließt, dass die verzichtbaren Heizelemente 3 und 4 im Gestrick des Flächenheizelementes jeweils einen Füllfaden bilden.From Fig. 2 results in the thread pattern of the electric surface heating element 1, wherein it is apparent that the dispensable heating elements 3 and 4 in the knitted fabric of the surface heating each form a filling thread.

Der so herstellbare elektrisch heizbare Stoff wird mit diesen zwei Fonturen 11 und 12 hergestellt. Hierbei ist eine der Fonturen am Umfang eines vertikalen Zylinders (nicht sichtbar) und die dazu senkrechte Nadelreihe am Umfang einer ebenfalls nicht sichtbaren horizontalen Scheibe angeordnet. Bevor die Maschen der Fontur 11 mit den Maschen der Fontur 12 vermascht werden, wird der elektrisch leitende Faden 13 dazwischen gelegt und somit fest eingebunden.Fig. 3 shows a schematically simplified representation of two fonts 11, 12 for explaining the production of a double knit. The electrically heatable fabric which can be produced in this way is produced with these two fonts 11 and 12. Here, one of the fonts on the circumference of a vertical cylinder (not visible) and the perpendicular row of needles on the periphery of a likewise not visible horizontal disc is arranged. Before the stitches of the fontur 11 are meshed with the stitches of the fontur 12, the electrically conductive thread 13 is placed therebetween and thus firmly integrated.
