Description
Gegenstand der Erfindung ist eine Anordnung an elektrischen Heizapparaten, Kochplatten o. dgl., bei denen der Heizleiter in keramische Masse eingebettet ist. Um den Heizwert solcher Platten zu erhöhen, muß außer der Zuführung größerer Energie eine Einrichtung getroffen werden, die eine größere Wärmeabgabe ermöglicht, damit nicht bei den hohen Stromstärken eine Überhitzung und Zerstörung des Heizleiters erfolgt. The invention relates to an arrangement of electrical heating devices, Hotplates or the like, in which the heating conductor is embedded in a ceramic mass. To the To increase the calorific value of such plates, besides the supply of greater energy, one must Means are taken that allows a greater heat dissipation so that the high currents do not overheat and destruction of the heating conductor takes place.
Gemäß der Erfindung wird als Heizleiter ein an sich für nicht eingebettete Heizkörper bekanntes, schraubenförmig hochkant gewickeltes Band verwendet, das auf Grund der größeren wärmeabgebenden Oberfläche bei großer Stromdichte höher belastbar ist als ein Material mit rundem Querschnitt, das bisher für diese Zwecke üblich war. Auf diese Weise kann auf dem gleichen Raum mehr Heizmaterial untergebracht werden, so daß ζ. Β. bei gleicher Größe einer Heizplatte eine größere Wärmewirkung erreicht wird. Die hochkant gewickelten Heizleiter haben gegenüber denen mit Runddrahtquerschnitt den besonderen Vorteil, daß sie beim Einpressen in keramisches Material leicht in die Masse eindringen und allseitig von dieser umgeben sind, so daß die Masse die Wärme gut aufnehmen kann. Da der Heizleiter auf 3» Grund der zuzuführenden Stromstärke einen Querschnitt besitzt, der der Wicklung bereits eine gewisse Festigkeit gibt, so sind irgendwelche Hilfsmittel zum Halten bzw. Aufwikkeln der Spulen nicht notwendig, und das Einpressen erfolgt ohne die Gefahr, daß benachbarte Wicklungen sich berühren und eine örtliche Überhitzung entsteht, die zur Zerstörung des Heizleiters führen würde.According to the invention, a heating element for non-embedded radiators is used as the heating conductor known, helically wound upright tape is used, which due to the larger heat-emitting surface is more resilient than at high current density a material with a round cross-section, which was previously common for these purposes. on this way, more heating material can be accommodated in the same space, like this that ζ. Β. with the same size of a heating plate, a greater thermal effect is achieved. The edgewise wound heating conductors have a cross-section compared to those with a round wire the particular advantage that they are easily inserted into the ceramic material when pressed Penetrate mass and are surrounded on all sides by this, so that the mass the heat well can accommodate. Since the heating conductor depends on the current intensity to be supplied Has a cross-section that already gives the winding a certain strength, so are any Tools for holding or winding the bobbins are not necessary, and that Pressing in takes place without the risk of neighboring Windings touch and local overheating occurs, which leads to destruction of the heatsealing band.
Die Abbildungen dienen zur Erläuterung der Erfindung. In Abb. 1 ist ein schraubenförmig gewickelter Heizleiter aus Bandmaterial ih stark vergrößertem Maßstab dargestellt. Abb. 2 zeigt den in die keramische Masse der Heizplatte α eingepreßten hochkant gewickelten Bandheizleiter b. The figures serve to explain the invention. In Fig. 1, a helically wound heating conductor made of strip material is shown in a greatly enlarged scale. Fig. 2 shows the band heating conductor b which is wound on edge and is pressed into the ceramic mass of the heating plate α.
