Description

Die Erfindung betrifft eine Massekochplatte aus 20
Glas und einem parallel zur Oberfläche des Kochplattenkörpers angeordneten flächigen Heizelement.The invention relates to a mass cooking plate from FIG
Glass and a flat heating element arranged parallel to the surface of the hotplate body.

Massekochplatten aus Glas sind an sich bekannt,
als Beheizung wurden bisher selbständige Elemente
vorgesehen, die in sich tragend gegen die Glasfläche 35
gepreßt wurden, wie z. B. Rohrheizkörper, oder auf
Glimmerträger gewickelte Heizdrähte (Zeitschrift
»technik und hausgeräte«, 1/70, S. 23 und 24), bzw.
flachbandartige Heizleiter (schweizerische Patentschrift 175 609). Alle diese Ausführungen besitzen 30
den Nachteil, daß die Wärmeübertragung an denMass cooking plates made of glass are known per se,
previously independent elements were used as heating
provided, which is self-supporting against the glass surface 35
were pressed, such as. B. tubular heater, or on
Mica carrier wound heating wires (magazine
»Technology and home appliances«, 1/70, pp. 23 and 24), or
flat band-like heating conductors (Swiss patent 175 609). All of these versions have 30
the disadvantage that the heat transfer to the

Glaskörper und weiter zum Kochtopf nicht optimal ist und Eich bei längeren Betriebsdauern noch verschlechtert, da die Anlage der Heizkörper gegen die Glasfläche über eine größere Anzahl von Temperatunvechseln nicht sicherzustellen ist. Darüber hinaus ist der erforderliche Aufwand hoch, da in jedem Fall temperaturbeständiges Trägermaterial, entweder als Außenhülle bei Rohrheizkörpern, oder Flachelemente zur Festlegung der Heizdrähte ebenso vorzusehen ist, wie eine Konstruktion, um den Heizkörper elastisch an die Fläche des Glaskörpers anzudrücken. Der Erfindung liegt die Aufgabe zugrunde, die Wärmeübergangsverhältnisse Heizelement — Glas zu verbessern. Erfindungsgemäß wird diese Aufgabe dadurch gelöst, daß das Heizelement aus Folie oder einer Schicht aus elektrisch leitendem Material besteht, die mit dem Kochplattenkörper verschmolzen ist. Damit sind die Wärmeübergangswerte Heizleiter — Kochplattenkörper optimal, eine Veränderung der Ubergangsverhältnisse ist auch bei sehr langen Betriebszeiten ausgeschlossen. Darüber hinaus bilden jetzt Kochplattenkörper und Heizleiter eine kompakte Einheit, die sich billig herstellen läßt und im Servicefall einfach auszutauschen ist. Zu beachten ist lediglich, daß die für den Kochplattenkörper zur Zeit in Frage kommenden Glassorten bei Temperaturen über 500° C elektrisch leitend werden. Für alle praktisch vorkommenden Koch- und Bratvorgänge über Kochplatten genügen jedoch Oberflächentemperaturen, die unter der genannten Temperaturgrenze liegen.The glass body and further to the saucepan is not optimal and the calibration is still worsened over longer periods of operation, because the installation of the radiator against the glass surface changes over a large number of temperatures cannot be guaranteed. In addition, the effort required is high in every case temperature-resistant carrier material, either as an outer shell for tubular heating elements, or flat elements to fix the heating wires is to be provided as well as a construction to the radiator to press elastically against the surface of the glass body. The invention is based on the object Improve heat transfer ratios between heating element and glass. This object is achieved according to the invention solved in that the heating element consists of foil or a layer of electrically conductive material, which is fused to the hotplate body. The heat transfer values are thus heat conductors - Hotplate body optimal, a change in the transition ratios is also possible with very long operating times locked out. In addition, the hotplate body and heating conductor now form a compact one Unit that can be manufactured cheaply and easily exchanged in the event of service. Please note only that the types of glass currently in question for the hotplate body at temperatures become electrically conductive above 500 ° C. For all practically occurring cooking and roasting processes However, above hotplates, surface temperatures below the stated temperature limit are sufficient lie.
