Kochplatte aus GlaskeramikGlass ceramic hotplate
Die Neueriing betrifft eine Kochplatte aus Glaskeramik mit einem die Kochplatte vor Übertemperaturen schützenden Stabausdehnungsregler und ä.nem spiralförmig verlaufenden elektrischen Mantelrohrheizstab, der mittels eines Isolierkörpers gegen die Unterseite der Kochplatte gepreßt ist.The novelty concerns a hotplate made of glass ceramic with a rod expansion regulator that protects the hotplate from excess temperatures and a similar electrical device running in a spiral shape Jacketed heating rod, which by means of an insulating body is pressed against the underside of the hotplate.
Kochplatten dieser Art sind bekannt (DT-OS 2 211 855, DT-OS 2 219 890). Bei diesen bekannten Kochplatten ist der spiralförmig verlaufende Mantelrohrheizstab in muldenartigen Vertiefungen in dem den Mantelrohrheizstab gegen die Unterseite pressenden Isolierkörper geführt.Hotplates of this type are known (DT-OS 2 211 855, DT-OS 2 219 890). In these known hotplates, it is spiral-shaped Running jacket tube heating rod in trough-like depressions guided in the insulating body pressing the tubular heating rod against the underside.

Demgegenüber ist; die Neuerung dadurch daß der spiralförmig verlaufende elektrische Mantelrohrheizstab plan auf dem Isolierkörper aufliegt und die zum elektrischen Anschluß führenden Enden des Mantelrohrheizstabes und der Stabausdehnungsregler in je einer muldenartigen Vertiefung im Isolierkörper geführt sind.In contrast is; the innovation in that the spiral-shaped electric tubular heating rod rests flat on the insulating body and the ends of the tubular heating rod leading to the electrical connection and the rod expansion regulator are each guided in a trough-like recess in the insulating body.
Ein Ausführungsbeispiel der Neuerung ist in der Zeichnung dargestellt und wird im folgenden näher beschrieben. Die Zeichnung zeigt eine Kochplatte aus Glaskeramik im senkrechten Mittelschnitt.An embodiment of the innovation is shown in the drawing and is described in more detail below. The drawing shows a hotplate made of glass ceramic in a vertical center section.
Die in der Zeichnung dargestellte Kochplatte 1 besteht aus einer temperaturbeständigen Glaskeramikplatte 2 sowie einem unterhalb der Glaskeramikplatte angeordneten spiralförmig verlaufenden elektrischen Mantelrohrheizstab 3. Die Windungen des MantelrohrheizStabes 3 liegen auf einem Isolierkörper 4 plan auf und werden mittels dieses Isolierkörpers fest gegen die Unterseite der Glaskeramikplatte 1 gepreßt. Die zum nicht dargestellten elektrischen Anschluß führenden Enden 5 des Mantelrohrheizstäbes 3 sind in einer im Isolierkörper 4 angeordneten muldenartigen Vertiefung geführt. Um die Glaskeramikplatte 2 vor Ubertempe^aturen zu schützen, ist unterhalb der Glaskeramikplatte 2 ein Stabausdelinungsregler 7 angeordnet, dessen Länge in etwa dem Durchmesser der Glaskeramikplatte 2 entspricht. Für den Stabausdehnungsregler 7 ist im Isolierkörper 4 ebenfalls eine muldenartige Vertiefung 8 zur Führung vorgesehen. Die Unterseite des Isolierkörpers 4 ist mittels einer vorzugsweise aus Weißblech bestehenden Bodenplatte 9 abgedeckt.The hotplate 1 shown in the drawing consists of a temperature-resistant glass ceramic plate 2 as well a spiral-shaped electric jacket tube heating rod 3 arranged below the glass ceramic plate Coils of the tubular heating rod 3 lie on an insulating body 4 and are firmly against the underside of the glass ceramic plate 1 by means of this insulating body pressed. The leading to the electrical connection, not shown, ends 5 of the tubular heating rods 3 are in a guided in the insulating body 4 arranged trough-like recess. To the glass ceramic plate 2 before Ubertempe ^ aturen To protect, there is a rod expansion regulator underneath the glass ceramic plate 2 7 arranged, the length of which corresponds approximately to the diameter of the glass ceramic plate 2. For the rod expansion controller 7, a trough-like recess 8 is also provided in the insulating body 4 for guidance. The bottom the insulating body 4 is covered by means of a base plate 9, which is preferably made of tinplate.
