Description
Elektrische Heizeinrichtung Bei den bisher gebräuchlichen Heizeinrichtungen, beispielsweise .für Kochzwecke, liegen die Heizwiderstände offen und es besteht kein genügender Schutz gegen uribeabsichtigte Bierehrung spannungführender Teile mit der Hand. Man hat daher vorgeschlagen, die Heizwiderstände mit metallischen Schutzgittern zu,überdecken. Dies bietet aber nur solange Schutz, als die Heizwiderstände unversehrt sind. Reißt ein Heizdraht aus irgendeinem Grunde, so kann er gegen das Schutzgitter schnellen und es unter Spannung setzen, so daß .die Berührungsgefahr nicht vermieden ist.Electric heating device With the previously used heating devices, For example, for cooking purposes, the heating resistors are open and there is Insufficient protection against unintentional beer damage of live parts with the hand. It has therefore been proposed that the heating resistors with metallic Protective grids to cover. However, this only offers protection as long as the heating resistors are intact. If a heating wire breaks for any reason, it can work against that The protective grille snap up and energize it so that there is a risk of contact is not avoided.
Gegenstand der Erfindung ist eine elektrische Heizeinrichtung, bei der die He@zwiderstände in keramischen Haltern angeordnet sind, .die als Platte mit Durchbrechungen von solcher Größe ausgebildet sind, daß eine zufällige Berührung ,der Heizwiderstände mit der Hand ausgeschlossen ist. Die Erfindung besteht darin, .daß die Heizwiderstände zwischen den festen Stegen beiderseits von je zwei Durchbrechungen der Platten liegen.The invention relates to an electrical heating device which the He @ resistors are arranged in ceramic holders, .the as a plate are formed with openings of such a size that accidental contact , the heating resistors by hand is excluded. The invention consists in .that the heating resistors between the fixed webs on both sides of two openings of the plates.
In der Zeichnung ist in Schnitten und Ansicht eine A_ usführungsform der Erfindung dargestellt. Bei diesem Beispiel sind ebene Platten mit gerade geführtem Heizleiter angenommen. Es steht natürlich nichts im Wege, die Heizleiter nach anderen Kurven, z. B. nach Kreisen oder Spiralen, zu führen oder die keramischen Platten zu wölben.The drawing shows an embodiment in sections and elevation of the invention shown. In this example are flat plates with straight out Heat conductor accepted. Of course, nothing stands in the way, the heating conductors after another Curves, e.g. B. according to circles or spirals, or the ceramic plates to bulge.
Bei der Einrichtung gemäß der Abbildung sind zwei keramische Platten a und b angeordnet. Die Heizleiter e liegen auf den festen Stegen bi der unteren Platte b und unterhalb der festen Stege ai der oberen Platte a. Die Durchbrechungen f und g sind als Kanäle ausgebildet, und die Stege sind nach den Heizleitern hin zugespitzt, so daß sich neben den Leitexn breite, an der Oberfläche der Platten a und b schmale Räume ergeben, durch welche die Wärme gut abgeführt wird, ohne daß eine unbeabsichtigte Berührung der spannungführenden Heizleiter von Hand möglich ist. Die Rippen lt und i können sehr schmal gewählt werden.In the device according to the figure, two ceramic plates a and b are arranged. The heating conductors e lie on the fixed webs bi of the lower plate b and below the fixed webs ai of the upper plate a. The openings f and g are designed as channels, and the webs are pointed towards the heating conductors, so that next to the Leitexn there are wide spaces on the surface of the plates a and b, through which the heat is dissipated well without unintentional touching of the live heating conductor by hand is possible. The ribs lt and i can be chosen to be very narrow.
Die beschriebene Einrichtung hat den Vorteil, daß die wärmespeichernde Wirkung der keramischen Platten auf ein geringes Maß herabgesetzt ist und dennoch .eine genügende mechanische Festigkeit der Platten gewährleistet ist.The device described has the advantage that the heat-storing Effect of the ceramic plates is reduced to a small extent and yet . A sufficient mechanical strength of the plates is guaranteed.
