Description

Elektrische Kochplatten mit verdeckt angeordnetem Heizkörper, sogenannte geschlossene Kochplatten, haben, soweit es sich tun Geräte hoher Leistung handelt, zwischen dem eigentliehen Heizleiter und dem Metallgehäuse eine Isolation aus keramischem Material. Dieses ist Leiter zweiter Klasse, und so fließen bei den hohen Betriebstemperaturen vom Heizleiter zum Metallgehäuse Ströme ab, die für den Bedienenden nicht ungefährlich sind. Dieses Moment tritt zur Zeit um so mehr in Erscheinung, als bei den jetzt im Vordergrund des wirtschaftlichen Interesses stehenden Hochleistungskochplatten wesentlich höhere Temperaturen auftreten.Electric hotplates with concealed heating elements, so-called closed ones Hotplates have, as far as there are high-performance devices, between the real ones Heating conductor and the metal housing an insulation made of ceramic material. This is a second class conductor, and so flow from the heating conductor at the high operating temperatures to the metal housing, currents that are not harmless for the operator. This The moment appears all the more at the moment than with the now in the foreground of the economic Interesting high-performance hotplates, significantly higher temperatures occur.

Vorliegende Erfindung betrifft eine Kochplatte, deren Gehäuse auch bei solchen Temperaturen nicht spannungführend wird. Erfindungsgemäß wird dies dadurch erreicht, daß bei dem von dem äußeren Gehäuse in der heißen Zone durch einen Luftraum getrennten Heizkörper die Abstützungen des Heizleiterträgers gegen das Metallgehäuse an Stellen niedriger Temperatur elektrisch isoliert sind. In der Zeichnung ist die Erfindung in einem Ausführungsbeispiel dargestellt.The present invention relates to a hotplate, the housing of which also at such temperatures does not become live. According to the invention this is achieved in that where separated from the outer housing in the hot zone by an air space Radiator supports the heatsealing band against the metal housing in places are electrically insulated at a low temperature. In the drawing the invention is in one Embodiment shown.

Die Abbildung veranschaulicht in schematischer Darstellung den Aufbau des gesamten Gerätes. Auf die Grundfläche 1 sind metallische Stäbe 2 unter Zwischenlage von Isoliermaterial 3 aufgeschraubt. Die Stäbe tragen den Reflektor 4, dessen Seitenwand bei 40 wieder nach innen zurückgewölbt ist. In der Wand des Reflektors sind die den Heizkörper 5 tragenden Stäbe 6 befestigt. Die Zuleitungsenden des Heizdrahtes 7 sind in Buchsen 8 durch den Reflektor hindurchgeführt. Die Anschlußenden vereinigen sich in einem Wechselschalter 9. Der ganze Aufbau wird von dem zylindrischen Gehäuse 10 umschlossen, auf welchem oben die als Kochfläche dienende metallische Platte 11 angeordnet ist. Die Seitenwand 10 ist an einigen Stellen io° über die Bodenfläche ι hinaus verlängert und bildet an diesen Verlängerungen die Füße des Gerätes.The figure shows the structure of the entire device in a schematic representation. Metallic rods 2 are screwed onto the base 1 with insulating material 3 in between. The bars carrying the reflector 4, the side wall is arched back inward again at 4 0th In the wall of the reflector, the rods 6 carrying the radiator 5 are attached. The lead ends of the heating wire 7 are passed in sockets 8 through the reflector. The connection ends unite in a changeover switch 9. The entire structure is enclosed by the cylindrical housing 10, on which the metal plate 11 serving as a cooking surface is arranged at the top. The side wall 10 is extended at some points io ° beyond the bottom surface ι and forms the feet of the device on these extensions.

Der Heizleiterträger ist also bei vorliegender Erfindung von dem äußeren Gehäuse nochmals elektrisch isoliert, und zwar an einer Stelle niedriger Temperatur. Ein Abfließen von Strömen bei heißer Kochplatte ist somit unterbunden. In the present invention, the heat conductor carrier is thus once again from the outer housing electrically isolated, in a place of low temperature. A drain of Flow when the hotplate is hot is thus prevented.
