Description

Bei elektrischen Glü?ikoohplatten besteht der wesentliche Nachteil, daß die gesamte Heizfläche nicht gleichmäßig Wärme ausstrahlt. In der Plattenruitte treten Wärmestauungen auf, wodurch besonders eine Anbrenngefahr in der Mitte des Kochgefäßes gegeben ist.The main disadvantage of electric hot plates is that that the entire heating surface does not radiate heat evenly. In the tiled floor heat build-up occurs, which creates a risk of being burned in the middle of the Cooking vessel is given.

Die vorliegende Erfindung vermeidet diese Nachteile in einfachster Weise dadurch, daß der Abstand der einzelnen Windungen des Heizdrahtes bzw. der Rillen, die den Heizdraht aufnehmen, an den Randflächen der Platte eng und gegen die Mitte der Platte zu weiter werdend ausgebildet ist. Die Anordnung der Rillen kann dabei so vorgesehen sein, daß in der Plattenmitte eine =beheizte Fläche vorhanden ist, so daß Wärmestauungen dort nicht mehr auftreten können. Durch die erfindungsgemäße Anordnung der Rillen ist es auch möglich, der Außenwand der innenliegenden Rillen eine größere Neigung zu geben, z. B. 35°, als der Außenwand der übrigen, mehr am Plattenrand liegenden Rillen, die z. B. eine Neigung von io° aufweisen.The present invention avoids these disadvantages in the simplest possible way Way in that the distance between the individual turns of the heating wire or the Grooves, which take up the heating wire, on the edge surfaces of the plate close and against the center of the plate is designed to become wider. The arrangement of the grooves can be provided in such a way that there is a heated surface in the middle of the plate so that heat build-up can no longer occur there. By the invention It is also possible to arrange the grooves on the outer wall of the internal grooves a greater tendency to give, e.g. B. 35 °, than the outer wall of the rest, more on Plate edge lying grooves, the z. B. have an inclination of io °.

In der Figur ist die Erfindung an einem Ausführungsbeispiel dargestellt. Es ist eine Platte i aus keramischem Baustoff gezeigt, welche spiralig verlaufende Rillen 2 aufweist. Hierbei ist der Ab- stand 3 der Rillen, die den Heiz-draiht aufnehmen, am Plattenrand enger und gegen die Plattenmitte zu weiter werdend ausgebildet. In der Plattenmitte 4 ist eine unbeheizte Fläche vorgesehen, um die ihier durch Wärmestauung besonders. auftretende Anbrenngefahr zu beseitigen. Die Außenwand 5 der um die Plattenmitte liegenden Rille weist beispielsweise eine Neigung von 35° auf, während die Außenwand 6 der am Plattenrand liegenden Rillen beispielsweise mit einer Neigung von io° ausgebildet ist.In the figure, the invention is shown in one embodiment. A plate i made of ceramic building material is shown, which has grooves 2 running in a spiral. Here, the waste was 3 of the grooves that receive the heating draiht, formed narrower edge of the plate and at the center of the board to further becoming. In the middle of the plate 4 an unheated area is provided in order to protect it especially through heat build-up. to eliminate any risk of scalding. The outer wall 5 of the groove located around the center of the plate has, for example, an inclination of 35 °, while the outer wall 6 of the grooves located on the edge of the plate is designed, for example, with an inclination of 10 °.
