Description
Elektrische Hochleisturigskochplätten aus Metall, bei denen, um eine gleichmäßige Randbeheizung der Kochplatte zu erreichen, an der Unterseite der Metallplatte zwischen Wärmeleitrippen Hochleistungsheizwicklungen eingebettet sind und bei denen nahe. am Plattenrand ein Teil der Heizwicklung in einer davon gleichmäßig entfernt verlaufenden Rille eingebettet ist, sind bekannt. Die Heizwicklungen an der Unterseite der Metallplatte, zwischen denen die Wärmeleitrippen eingebettet sind, verlaufen konzentrisch. ■ ' Demgegenüber werden bei der Hochleistungskochplatte nach der Erfindung' kreisförmig und spiralförmig angeordnete Heizwicklungen verwendet, und zwar derart, daß nahe am Plattenrand ein Teil der Heizwicklung in einer vom Rand gleichmäßig entfernt in Kreisform verlaufenden Rille untergebracht ist, so daß die weniger beheizte Stelle am Anfang der Spirale in einer mittleren Zone der Kochplatte, die von der Umgebung mitbeheizt wird, liegt. An diese Rille erst schließt sich die ein- oder mehrgängige Spirale an, die in bekannter Weise den Rest der Wicklungen aufnimmt. Zweckmäßig wird man in die äußere Rille einen Teil einer Wicklung mit hoher Leistung verlegen. Man kann jedoch auch, um mehr Schaltstufen zu erhalten, eine besondere Wicklung in die äußere Rille verlegen.High-performance electric metal cooktops, which, in order to ensure uniformity To achieve edge heating of the hotplate, on the underside of the metal plate between Heat-conducting ribs high-performance heating windings are embedded and where close. at the Plate edge part of the heating winding in one that runs evenly away from it Groove is embedded are known. The heating coils on the underside of the metal plate, between which the heat conducting ribs are embedded, run concentrically. ■ ' In contrast, the high-performance hotplate according to the invention 'becomes circular and spirally arranged heating coils used, in such a way that close to the plate edge a part of the heating coil housed in a circular groove evenly spaced from the edge is so that the less heated point at the beginning of the spiral in a middle Zone of the hotplate, which is also heated by the surroundings. To this groove only the single or multi-start spiral follows, which in a known way does the rest the windings. Appropriately, one becomes part of a in the outer groove Lay the winding with high power. However, you can also to get more switching steps get a special winding in the outer groove.
Der Vorteil der vorliegenden Erfindung besteht darin, daß durch die Ausbildung der äußeren Rille in Kreisform die weniger beheizte Stelle am Anfang der Spirale in einer mittleren Zone der Kochplatte liegt, die von der Umgebung mitbeheizt wird. Hierdurch wird auch bei Kochplatten, deren Heizkörper zum größten Teil spiralförmig angeordnet sind, sowohl eine gleichmäßige Randbeheizung der Kochplatte als auch eine gleichmäßige Temperatürverteilung auf der ganzen Platte erreicht.The advantage of the present invention is that by forming the outer groove in circular shape the less heated point at the beginning of the spiral in one middle zone of the hotplate, which is also heated by the environment. Through this is also used for hotplates, the heating elements of which are for the most part arranged in a spiral are, both a uniform edge heating of the hotplate and a uniform Achieved temperature distribution over the whole plate.
In den Abbildungen ist ein Ausführungsbeispiel dargestellt. In Fig. 1 bedeutet α den Anfang, b das Ende der äußeren Rillei g, c den Anfang, d das Ende der in der Spirale verlegten starken Heizwicklung, e den Anfang, f das Ende der in der Spirale verlegten schwachen Heizwicklung. Im gezeichneten Beispiel ist die Heizwicklung in der äußeren Rille ein Teil der Wicklung mit hoher Leistung; dementsprechend sind die beiden Enden b und c miteinander verbunden.An exemplary embodiment is shown in the figures. In Fig. 1, α means the beginning, b the end of the outer groove g, c the beginning, d the end of the strong heating winding laid in the spiral, e the beginning, f the end of the weak heating winding laid in the spiral. In the example shown, the heating winding in the outer groove is part of the winding with high power; accordingly, the two ends b and c are connected to one another.
