Description

Elektrisches Heizelement und Verfahren zu seiner Herstellung Die Erfindung betrifft ein aus einem Isolierkörper und einem darin angeordneten Heizleiter bestehendes Heizelement, das zum Einbau in verschiedenartige Beheizungseinrichtungen und Heizgeräte, wie auch als Hez- oder Warmhalteplatte verwendet werden kann, wobei die mögliche Temperaturbelastung vorzugsweise bei etwa 350 0 C und darunter liegen soll. Electric heating element and process for its manufacture The invention relates to an insulating body and a heating conductor arranged therein Existing heating element that can be installed in various types of heating equipment and heaters, as can also be used as a hot plate or hot plate, whereby the possible temperature load is preferably about 350 ° C. and below target.

Es sind Heizelemente verschiedener Art bekannt, bei denen der Heizleiter in Rillen oder Nuten von Vorgeferigten keramischen Platten o.dgl. eingebettet ist. Bekannt sind auch plattenförmige Heizelemenvte, deren Heizleiter zwischen Isolierpiatten-angeordnet ist, die miteinander verklebt sind.There are heating elements of various types known in which the heating conductor in grooves or grooves of prefabricated ceramic plates or the like. is embedded. Plate-shaped heating elements, whose heating conductors are arranged between insulating plates, are also known that are glued together.

Außerdemkennt man bereits Heizelemente, bei denen der Heizleiter in einer kalt abbindenden Xeramikmasse eingebettet ist, die sandwichartig zwischen dünnen Isolierplatten lagert.In addition, one already knows heating elements in which the heating conductor is in a cold-setting xeramik mass is embedded, which is sandwiched between thin insulating plates.

Nachteile dieser bekannten Heizelemente bestehen darin, daß deren Herstellung einen verhältnismäßig hohen Zeitaufwand erfordert und, soweit vorgefertigte Keramikteile verwendet werden, eine entsprechende umfangreiche Lagerhaltung notwendig ist.Disadvantages of these known heating elements are that their Production requires a relatively high expenditure of time and, as far as prefabricated Ceramic parts are used, a corresponding extensive storage necessary is.

Um diese Nachteile zu beheben, wird gemäß vorliegender Erfindung vorgeschlagen, den Heizleiter unmittelbar in eine kun@tstoffgebundene Isoliermasse einzubetten, die unter bnwendung von Wärme und Druck zu der gewiinschten Form des ReizelotontS gerresst wird.In order to remedy these disadvantages, it is proposed according to the present invention, to embed the heating conductor directly in a plastic-bound insulating compound, the application of heat and pressure to the desired shape of the stimulus tone is stressed.

Dieses neuartige Heizelement ist in weder beliebigen Form in sehr wirtschaftlicher Weise herzustellen, wobei noch als besonderer Vorteil zu nennen ist, daß die Isoliermasse in pulveriger oder körniger Form verarbeitet und vor der Verarbeitung beliebig lange und ohne besondere Vorkehrungen gelagert werden kann.This novel heating element is in neither any form in very much to be produced economically, although this should be mentioned as a particular advantage is that the insulation is processed in powder or granular form and before Processing can be stored for any length of time and without special precautions.

Gemäß einem weiteren Merkmal der Erfindung können die durch Beimengung von Farbstoffen beliebig färbbaren Heizelemente noch mit einer Glasur an sich bekannter Art überzogen und dadurch zusätzlich oberflächengeschützt werden.According to a further feature of the invention, by adding of dyes any colorable heating elements with a glaze per se known Art coated and thus additionally protected on the surface.

Der Gegenstand der Erdindung ist in einem Ausführungsbeispiel einer Zeichnung dargestellt.The subject matter of the earth connection, in one embodiment, is one Drawing shown.

Das als Beispiel gewählte Heizelement besteht aus einer zu der gewünschten Fc'r des Elments epressten Isoliermasse 1, einem als Werdel geformten Heizleiter 2 und den mit in die Masse 1 eingebetteten Heizleiteranschlüssen 3 und 4.The heating element chosen as an example consists of one of the desired ones Fc'r of the element epressed insulating compound 1, a heating conductor shaped as a Werdel 2 and the heating conductor connections 3 and 4 embedded in the ground 1.

Die Isoliermasse 1 besteht aus einem keramischen Granulat, beispielsweise aus Quarzsand und einem Kunststoffbinder an sich bekannter Art. Der Heizleiter 2 wird bei der Herstellung des Heizelements in einem Preß- und Formwerkzeug in die Isoliermasse eingelagert und dann die Masse unter Anwendung von Wärme in die Form gepresst. Der Isoliermasse können vor dem Pressen beliebige Parbstoffe zugesetzt und damit das Heizelement in Jeder gewünschten Farbe hergestellt werden.The insulating compound 1 consists of a ceramic granulate, for example made of quartz sand and a plastic binder of a type known per se is in the manufacture of the heating element in a pressing and molding tool in the Insulating compound is stored and then the compound is put into the mold with the application of heat pressed. Any paring agents can be added to the insulating compound before pressing and so that the heating element can be produced in any desired color.

Abschließend kann das Heizelement noch mit einer Glasur keramischer, organischer oder halborganischer Art versehen und dadurch noch zusätzlich an~seiner Oberfläche geschutzt werden.Finally, the heating element can be glazed with ceramic, of an organic or semi-organic nature and thus additionally different Surface are protected.

Die mögliche Temperaturbelastung dieser Heizelemente ist abhängig von dem verwendeten Kunststoffbinder und liegt bei den-derzeit bekannten Bindern bei etwa 350 0.The possible temperature load on these heating elements depends of the plastic binder used and is in the currently known binders at around 350 0.

Ergänzend wird noch hinzugefügt, daß anstelle des wendelförmigen Heizleiters auch jede andere Art, beispielsweise auch bazidförmige Heizleiter -verwendet werden können.In addition, it is also added that instead of the helical heating conductor any other type, for example also bazid-shaped heating conductors, can be used can.
