Description

Die vorliegende Erfindung betrifft einen elektrischen Flächenheizkörper nach dem Oberbegriff des Anspruchs 1.The present invention relates to an electric surface heater according to the preamble of claim 1.

Aus der DE 37 11 035 C2 ist ein gattungsgemäßer Flächenheizkörper bekannt. Als elektrische Heizeinrichtung wird hierbei ein Heizleiter in Form eines Flachdrahtes auf eine Strahlungsfolie meanderförmig aufgedruckt, aufkaschiert oder in ähnlicher Weise aufgebracht. Die Strahlungsfolie ist wiederum mit einer Wärmedämmplatte zu einer Baueinheit verbunden. Die Baueinheit bestehend aus Heizleiter, Strahlungsfolie und Wärmedämmplatte wird an der Rückseite einer Platte aus wärmeleitfähigem Material befestigt. Die Konstruktion ist in ihrer Herstellung aufwendig und daher teuer.From the DE 37 11 035 C2 is a generic surface heater known. In this case, a heating conductor in the form of a flat wire is imprinted in a meandering manner on a radiation foil, laminated or applied in a similar manner as an electrical heating device. The radiation film is in turn connected to a thermal insulation panel to form a structural unit. The assembly consisting of heat conductor, radiation foil and thermal insulation board is attached to the back of a plate made of thermally conductive material. The construction is expensive to manufacture and therefore expensive.

Aus der WO 03/073792 A2 ist ein Flächenheizkörper bekannt, der eine Platte aus wärmeleitfähigem Material, z. B. Marmor, sowie eine zusätzliche Trägerplatte mit einer beheizbaren Deckschicht zur Beheizung der Platte aufweist. Gemäß einer Ausgestaltung dieser Idee sind als Heizelement fein verteilte Graphiteilchen in einer hitzebeständigen Kunststofffolie untergebracht. Auch diese Anordnung ist in ihrer Konstruktion aufwendig und teuer in der Umsetzung.From the WO 03/073792 A2 is a surface heater known, which is a plate of thermally conductive material, eg. As marble, as well as an additional support plate having a heated cover layer for heating the plate. According to one embodiment of this idea finely distributed graphite particles are housed in a heat-resistant plastic film as a heating element. This arrangement is complex in construction and expensive to implement.

Die Aufgabe der vorliegenden Erfindung besteht darin, einen neuartigen elektrischen Flächenheizkörper der eingangs genannten Art zur Verfügung zu stellen, welcher eine besonders einfach zu realisierende Konstruktion gewährleistet, gleichzeitig jedoch eine im Vergleich zum Stand der Technik erhöhte Heizwirksamkeit entfaltet.The object of the present invention is to provide a novel electric surface heater of the type mentioned above, which ensures a particularly easy-to-implement construction, but at the same time unfolds an increased compared to the prior art heating efficiency.

Die vorstehende Aufgabe wird bei dem gattungsgemäßen Flächenheizkörper dadurch gelöst, dass als elektrische Heizeinrichtung Karbonfasern vorgesehen sind, die Bestandteile eines temperaturbeständigen Trägers sind. Die Verwendung von Karbonfasern ermöglicht es, Letztere in einen flächigen Träger in einfacher und kostengünstiger Weise einzubringen, beispielsweise einzuweben. Zum anderen gewährleistet die Verwendung von den Karbonfasern einen vorteilhaften Wirkungsgrad und hohe Flexibilität beim Beheizen der Platte.The above object is achieved in the generic surface heating element in that are provided as electrical heating carbon fibers, which are components of a temperature-resistant support. The use of carbon fibers makes it possible to introduce the latter into a flat carrier in a simple and cost-effective manner, for example weaving. On the other hand, the use of the carbon fibers ensures advantageous efficiency and high flexibility in heating the plate.

Vorteilhafterweise handelt es sich bei dem Träger um ein Gewebe aus temperaturbeständigen Fasern. Dieses Gewebe kann auf der Grundlage üblicher Webverfahren hergestellt werden.Advantageously, the carrier is a fabric of temperature-resistant fibers. This fabric can be made based on conventional weaving techniques.

Zweckmäßigerweise handelt es sich bei dem Gewebe um ein Glasfasergewebe. Dieses eignet sich ganz besonders aufgrund seiner Temperaturbeständigkeit, Karbonfasern aufzunehmen.Conveniently, the fabric is a glass fiber fabric. This is particularly suitable because of its temperature resistance to absorb carbon fibers.

Gemäß der Erfindung sind die Karbonfasern in das Gewebe eingewoben, beispielsweise in Form von so genannten Schussfäden. Die Art des Einsatzes der Karbonfasern ermöglicht es zudem, in einfacher Weise eine unterschiedliche Anordnung derselben am Träger vorzusehen. Dies dient dazu, bestimmte Bereiche des Trägers, beispielsweise dessen Randbereiche, stärker zu erhitzen, um wiederum ein besseres Verhältnis von Heizleistung des Flächenheizkörpers und notwendiger elektrischer Energie zu erreichen. Insbesondere kann die Platte hierdurch mit einer idealen Heizleistungsverteilung betrieben werden.According to the invention, the carbon fibers are woven into the fabric, for example in the form of weft threads. The nature of the use of carbon fibers also makes it possible to provide a different arrangement of the same on the carrier in a simple manner. This serves to heat certain areas of the carrier, for example its edge areas, more strongly, in turn, to achieve a better ratio of heating power of the surface heating element and necessary electrical energy. In particular, the plate can thereby be operated with an ideal heating power distribution.

Die Anordnung der Karbonfasern am Träger ist vorzugsweise unterschiedlich, so dass die Heizleistung im Randbereich des Trägers beispielsweise höher ist als im Mittelbereich.The arrangement of the carbon fibers on the carrier is preferably different, so that the heating power in the edge region of the carrier, for example, is higher than in the central region.

Insbesondere kann der Abstand der Karbonfasern in dem Gewebe zueinander variiert werden, um eine solche unterschiedliche Anordnung zu gewährleisten.In particular, the distance of the carbon fibers in the fabric from each other can be varied to ensure such a different arrangement.

Der Träger ist in einfacher Weise mit der Platte durch Aufkleben verbunden, so dass aufwendige Montagearbeiten bzw. Bearbeitungen der Platte wegfallen.The carrier is connected in a simple manner with the plate by sticking, so that expensive installation work or processing of the plate omitted.

Zweckmäßigerweise kann eine vorzugsweise innenseitig Wärme reflektierende Abdeckplatte auf der der Platte gegenüber liegenden Seite des Trägers zum Schutz vor mechanischer Beeinträchtigung vorgesehen sein.Conveniently, a preferably inside heat-reflecting cover plate may be provided on the side opposite the plate of the carrier for protection against mechanical impairment.

Alternativ oder zusätzlich können die Karbonfasern bereichsweise mit unterschiedlicher elektrischer Leistung betrieben werden, so dass sich hierdurch ein unterschiedlicher Heizeffekt in Bezug auf die jeweilige Position an der Platte einstellt.Alternatively or additionally, the carbon fibers can be operated in regions with different electrical power, so that in this way sets a different heating effect with respect to the respective position on the plate.

Alternativ oder zusätzlich hierzu können die Karbonfasern auch einen unterschiedlichen elektrischen Widerstand haben, so dass bei Anlegen eines Stroms sich unterschiedliche Heizleistungen ergeben.Alternatively or additionally, the carbon fibers may also have a different electrical resistance so that different heating powers result when a current is applied.

Diejenigen Karbonfasern, die einen höheren elektrischen Widerstand aufweisen, befinden sich zweckmäßigerweise im Randbereich des Trägers.Those carbon fibers which have a higher electrical resistance, are expediently in the edge region of the carrier.

Gemäß einer besonderen Ausgestaltung der vorliegenden Erfindung wird ein Teil der Karbonfasern aktiviert, so dass dieser Teil der Karbonfasern Hitzeenergie erzeugen kann, wohingegen der weitere Teil der Karbonfasern deaktiviert ist und keine Hitzeenergie erzeugt. Hierdurch kann durch geeignete Wahl der deaktivierten Karbonfasern ein Energieprofil über die Fläche des Trägers erstellt werden.According to a particular embodiment of the present invention, a part of the carbon fibers is activated so that this part of the carbon fibers can generate heat energy, whereas the other part of the carbon fibers is deactivated and does not generate heat energy. In this way, by appropriate choice of the deactivated carbon fibers, an energy profile can be created across the surface of the carrier.

Darüber hinaus ist es möglich, ausgehend von Standardgeweben, bei denen ein gleichmäßiger Abstand der Karbonfasern eingestellt ist, dennoch ein unterschiedliches Heizprofil durch entsprechende Deaktivierung einzelner Karbonfasern zu erzielen. Somit kann von einem vergleichsweise einfach und günstig zur Verfügung zu stellenden Trägermaterial eine individuelle Heizcharakteristik erstellt werden.Moreover, it is possible, starting from standard fabrics in which a uniform distance of the carbon fibers is set, yet to achieve a different heating profile by corresponding deactivation of individual carbon fibers. Thus, an individual heating characteristic can be created by a carrier material that is comparatively easy and cheap to provide.

Die Deaktivierung erfolgt zweckmäßigerweise durch einfaches Durchtrennen der Karbonfasern an den Bereichen, an denen die Hitzeentwicklung etwas zurückgenommen werden soll.The deactivation is conveniently carried out by simply cutting the carbon fibers at the areas where the heat is to be withdrawn something.

Bezugsziffer 1 in Fig. 1 kennzeichnet den Flächenheizkörper in seiner Gesamtheit. Er umfasst eine massive Platte 2 aus gut leitfähigem Material wie z. B. Naturstein wie etwa Marmor, Keramik oder Glas. Auch Metall wäre geeignet. Die Platte 2 dient dazu, die in ihr gespeicherte Wärme nach außen, insbesondere nach vorne, abzustrahlen.Reference numeral 1 in Fig. 1 identifies the surface heating element in its entirety. It includes a massive plate 2 made of good conductive material such. As natural stone such as marble, ceramics or glass. Also metal would be suitable. The plate 2 serves to radiate the heat stored in it to the outside, in particular to the front.

Auf der in Fig. 1 ersichtlichen Rückseite der Platte 2 befinden sich ein flächiger Träger 3 aus einem Gewebe aus temperaturbeständigen Fasern, beispielsweise Glasfasern 4 sowie Karbonfasern 5, die als Heizelemente vorgesehen sind. Hierzu stehen die Karbonfasern über eine geeignete elektrische Verbindung 10 mit dem Stromnetz in Verbindung.On the in Fig. 1 apparent back of the plate 2 are a flat carrier 3 made of a fabric made of temperature-resistant fibers, for example Glass fibers 4 and carbon fibers 5, which are provided as heating elements. For this purpose, the carbon fibers are connected via a suitable electrical connection 10 to the power grid.

An der Unterseite des Flächenheizkörpers 1 befindet sich beispielsweise sowohl an dessen Vorder- als auch Rückseite jeweils ein Fußteil 6 bzw. 7, so dass der Flächenheizkörper 1 an der gewünschten Stelle aufgestellt werden kann.At the bottom of the surface heating element 1, for example, both at the front and at the rear there is a respective foot part 6 or 7, so that the surface heating element 1 can be placed at the desired location.

Lediglich mit strichlierter Darstellung angedeutet ist eine Deckplatte 6 an der Rückseite des Flächenheizkörpers 1, die dazu dient, den Träger 3 vor mechanischen Beeinflussungen zu schützen.Only indicated by dashed lines is a cover plate 6 on the back of the surface heating element 1, which serves to protect the carrier 3 from mechanical influences.

Der Träger 3 wird als Gewebe in einfacher Weise auf die Rückseite der Platte 2 aufgeklebt. Die Klebeschicht ist in Fig. 2 mit der Bezugsziffer 8 gekennzeichnet.The carrier 3 is glued as a fabric in a simple manner on the back of the plate 2. The adhesive layer is in Fig. 2 denoted by the reference numeral 8.

Wie aus Fig. 1 ersichtlich ist, sind die Karbonfasern 5 in den Träger 3 in unterschiedlicher Anordnung, im Beispiel von Fig. 1 in unterschiedlichem Abstand A angeordnet. Hieraus resultiert, dass im Bereich der engeren Anordnung der Karbonfasern 5, also im seitlichen Randbereich von Fig. 1, eine im Vergleich zum Mittelteil erhöhte Temperatur (beispielsweise 110°C) auf die Platte 2 einwirkt als im Mittelbereich (beispielsweise 100°C). Durch das Einweben der Karbonfasern 5 in das Gewebe kann die vorgenannte Änderung der Anordnung der Karbonfasern 5 in einfacher Weise durchgeführt werden.How out Fig. 1 can be seen, the carbon fibers 5 in the carrier 3 in a different arrangement, in the example of Fig. 1 arranged at different distances A. This results in that in the region of the closer arrangement of the carbon fibers 5, ie in the lateral edge region of Fig. 1 , an elevated temperature (for example 110 ° C.) compared to the central part acts on the plate 2 than in the middle region (for example 100 ° C.). By weaving the carbon fibers 5 into the fabric, the aforesaid change in the arrangement of the carbon fibers 5 can be easily performed.

Die Abdeckplatte 6 weist eine Wärmereflektionsschicht 9 auf, die dafür sorgt, dass die von den Karbonfasern 5 erzeugte, nach hinten abgestrahlte Wärme zurück, d. h. in Richtung der Platte 2 reflektiert wird.The cover plate 6 has a heat reflection layer 9 which ensures that the heat radiated to the rear by the carbon fibers 5, that is, the heat radiated backwards. H. is reflected in the direction of the plate 2.

Fig. 3 zeigt in einer stark vereinfachten Ausschnittdarstellung den Träger 3, welcher ein Gewebe darstellt. In das Gewebe aus einzelnen kreuzweise verlaufenden Glasfasern 4 werden einzelne Karbonfasern 5 in entsprechender Orientierung, beispielsweise in Schussrichtung, eingewoben, und zwar in Fig. 3 mit einem gleich bleibenden Abstand zueinander. An einer bestimmten Stelle des Trägers 3 wird dann der Abstand der Karbonfasern 5 zueinander bedarfsweise verändert oder einzelne Karbonfasern 5 in dem Webmuster des Trägers 3 deaktiviert (siehe nachfolgende Ausführungen), um in diesem Bereich eine erhöhte bzw. reduzierte Heizleistung zu gewährleisten. Fig. 3 shows in a simplified sectional view of the carrier 3, which represents a tissue. In the tissue of individual crosswise extending glass fibers 4 individual carbon fibers 5 are woven in a corresponding orientation, for example in the weft direction, in Fig. 3 with a constant distance to each other. At a certain point of the carrier 3, the distance between the carbon fibers 5 is then changed as needed or individual carbon fibers 5 in the weave pattern of the carrier 3 is deactivated (see the following), in order to ensure increased or reduced heating power in this area.

Gemäß einer weiteren Ausgestaltung der vorliegenden Erfindung wird ein Teil der Karbonfasern, die in den Träger 3 eingewoben sind, dadurch deaktiviert, dass sie durchtrennt werden. Im Bereich dieser durchtrennten Karbonfasern ist folglich ein elektrischer Stromfluss nicht möglich und damit eine Erwärmung der betreffenden Karbonfaser nicht gegeben. Durch gezielte Auswahl derjenigen Karbonfasern, die deaktiviert werden sollen, kann die Einstellung einer gezielten Heizcharakteristik über die Gesamtfläche des Trägers 3 eingestellt werden.According to a further embodiment of the present invention, a part of the carbon fibers which are woven into the carrier 3 is deactivated by being severed. Consequently, in the region of these severed carbon fibers, an electric current flow is not possible and thus heating of the relevant carbon fiber is not possible. By selective selection of those carbon fibers that are to be deactivated, the setting of a targeted heating characteristic over the total area of the carrier 3 can be adjusted.
