Abstract
Description
Verfahren zur Herstellung einer Heizvorrichtung für Haushaltsgeräte und Geräte des persönlichen Bedarfs.Method of manufacturing a heating device for household appliances and devices for personal use.
Die Erfindung betrifft ein Verfahren zur Herstellung einer Heizvorrichtung für Haushaltsgeräte und Geräte des persönlichen Bedarfs, z.B. Bügeleisen, Toaster, Kaffeemaschinen, Heizgebläse, Haartrockner oder dergl.The invention relates to a method for producing a heating device for household appliances and devices for personal use, e.g. irons, toasters, Coffee machines, fan heaters, hair dryers or the like.
Bisher bekannte Heizvorrichtungen für Geräte dieser Art bestehen in der Regel aus einem Isolierkörper, auf oder um den massive Drähte oder Bänder aus einem Werkstoff mit geeignetem elektrischen Widerstand gewickelt sind, um die erforderliche, relativ hohe lleizleistung zu erreichen. Previously known heating devices for devices of this type exist usually from an insulating body, on or around the solid wires or tapes are wound from a material with suitable electrical resistance around the to achieve the required, relatively high licensing performance.
Die Herstellung derartiger' H'eizvorrichtungen ist umständlich, vergleichsweise teuer und ergibt h-Rufig schleohte Wärme übergänge vom Heizelement zu den zu erwärmenden Medien; überdies sind solche Heizvorrichtungen chemisch nicht beständig und daher für bestimmte Anwendungszwecke nicht geeignet. The manufacture of such 'heating devices' is cumbersome, comparatively expensive and results in bad heat transitions from the heating element to the one to be heated Media; moreover, such heating devices are not chemically stable and therefore not suitable for certain purposes.
Aufgabe der Erfindung ist es daher, die erstellung von Heizvorrichtungen der eingangs genannten Art zu vereinfachen und kostensparender zu gestalten, bei diesen.Vorrichtungen den Wärmeübergang vom-Wärmeerzeuger auf den Träger und/oder das zu erwärmende Medium zu verbessern und günstige Voraussetzungen für die Widerstandsfähigkeit gegen chemische Beanspruchungen solcher Vorrichtungen, zu schaffen. The object of the invention is therefore to create heating devices of the type mentioned to simplify and make more cost-effective These devices transfer the heat from the heat generator to the carrier and / or to improve the medium to be heated and favorable conditions for the resistance against chemical stresses of such devices.
Die erfindungegemäße Lösung der gestellten, Aufgabe besteht darin, daß auf einen nichtleitenden Träger, vorzugsweise Glaskeramik, wärmebeständiger Kunststoff, das Grundmuster der Heizleitung mit einem Material gleicher oder annähernd gleicher Wärmeausdehnung aufgetragen und anschließend in einem galvanischen Bad auf die der gewünschten Heizleistung angemessenen Dicke gebracht wird. The inventive solution of the task is to that on a non-conductive support, preferably glass ceramic, more heat-resistant Plastic, the basic pattern of the heating tape with a material that is the same or approximately applied with the same thermal expansion and then in a galvanic bath is brought to the thickness appropriate to the desired heating power.
Besonders bevorzugt wird eine Glaskeramik, die unter dem Warenzeichen "Cermet" der Firma "Schott und Genossen, Mainz" auf dem Markt -tst oder als Kunststoff ein glasfaserverstärktes Epoxydharz.A glass ceramic which is available under the trademark "Cermet" from the company "Schott and Comrades, Mainz" on the market or as plastic a glass fiber reinforced epoxy resin.
Das Grundmuster der Heizleitung kann durch Aufdampfen im Vakuum oder aber auch durch Aufdrucken einer Metall-verhindung in pastöser Form aufgetragen werden.The basic pattern of the heating cable can be made by vapor deposition in a vacuum or but also applied in pasty form by printing a metal barrier will.
In der nachstehend beschriebenen Zeichnung ist die Erfindung näher erläutert.The invention is illustrated in more detail in the drawing described below explained.
Auf einen Träger 1 aus wärmebeständigem Material,.On a carrier 1 made of heat-resistant material.
das eine unter dem Warenzeichen "Cermet" der Firma schott und Genossen, Mainz" auf dem Markt befindliche Glaskeramil sein kann, oder auch ein glasiaserverstärktes Epoxydharz, ist das Crundnuster 2 einer Heizleitung aufgetragen. Die Auftragung dieses Musters kann durch Aufdampfen von Chrora, Nickel oder dergl. im Vakuum oder durch Aufdrucken einer entsprechenden Metallverbindung in pastöser Form z.B.one under the trademark "Cermet" of the company schott and comrades, Mainz "can be the glass keramil available on the market, or a glass fiber reinforced one Epoxy resin, the base pattern 2 is applied to a heating cable. The application this pattern can by vapor deposition of Chrora, nickel or the like. In a vacuum or by printing a corresponding metal compound in pasty form e.g.
nach dem Siebdruckverfahren erfolgen. Anschließend wird dieser Erstauftrag der Heizleitung in einem galvanischen Bad auf die der gewünschten Reiz leistung angepaßten Dicke verstärkt 3.made by the screen printing process. Then this first order the heating cable in a galvanic bath to the desired stimulus performance adjusted thickness reinforced 3.
Wesentlich dabei ist es, daß der Wärmeausdehnungskoeffidient des Materials des Trägers 1 und der Reiz leitung 2,3 gl gleich oder annähernd gleich ist, so daß ein inniger Verbund dieser Materialien in bestimmungsgemäßen Temperaturbereich erhalten bleibt. Dieser Verbund kann im Falle der Verwendung von Epoxydharz von vornherein noch dadurch gefördert werden, daß das Harz vor dem Auftragen des Grundmusters nur vorgetrocknet, aber noch nicht ausgehärtet ist, so daß der feste Verbund erst beim völligen Aushärten des Trägers eintritt.It is essential that the coefficient of thermal expansion of the material of the carrier 1 and the stimulus line 2,3 gl is the same or approximately the same, so that an intimate bond of these materials is obtained in the intended temperature range remain. This composite can be used from the outset if epoxy resin is used can still be promoted by the fact that the resin only before the application of the basic pattern is predried, but not yet hardened, so that the solid bond is only when complete curing of the carrier occurs.
