Das in Fig. 1 nur teilweise dargestellt Einbau-Kochfeld 1 hat eine Glaskeramik-Kochfläche 2 mit mehreren beheizten Kochstellen und eine gegen die Unterseite der Kochfläche gepreßte Heizeinheit 3 für jede der Kochstellen. Die Heizeinheit 3 besteht aus eine Trägerschale 4 aus Blech und einem Isolierkörper 5 mit eingelegtem Heizleiter 6 (Drahtwendel). Sämtliche zum Einbau-Kochfeld 1 gehörenden Trägerschalen 4 sind in einer Muldenwanne 7 eingesetzt und dort in Lage zur jeweiligen Kochstelle hin unverrückbar festgelegt. Zum Festlegen der Trägerschale 4 in der Muldenwanne 7 und zum Anpressen der Trägerschale 4 mit dem Heizleiter 6 gegen die Unterseite der Glaskeramik-Kochfläche 2 sind zwei spezielle Doppelfederelemente 8 vorgesehen, die jeweils an der Trägerschale 4 gegenüberliegend angeordnet sind. Diese Federelemente sind dabei einerseits in Eingriff mit der Trägerschale 4 gebracht und andererseits an der Muldenwanne 7 eingehängt oder dort verrastet, wie später näher erläutert wird. Auf diese Weise wird die Heizeinheit 3 sowohl in ihrer Lage zur zugehörigen Kochstelle in der Muldenwanne 7 unverschiebbar festgelegt als auch gleichzeitig federnd gegen die Unterseite der Glaskeramik-Kochfläche 2 gepreßt.The only partially shown in Fig. 1 built-in hob 1 has a glass ceramic cooking surface 2 with several heated burners and a heating unit pressed against the underside of the cooking surface 3 for each of the hobs. The heating unit 3 is made from a carrier shell 4 made of sheet metal and an insulating body 5 with pickled heating element 6 (wire helix). All to the built-in hob 1 belonging carrier shells 4 are in a trough 7 inserted and there immovable in position to the respective cooking point established. To set the carrier shell 4 in the Trough 7 and for pressing the carrier shell 4 with the Heating conductor 6 against the underside of the glass ceramic cooking surface. 2 two special double spring elements 8 are provided, each are arranged opposite to the support shell 4. These spring elements are on the one hand in engagement with the Carrier tray 4 brought and on the other hand to the trough 7 hung or locked there, as explained later becomes. In this way, the heating unit 3 in both their Position to the associated hotplate in the trough 7 immovable fixed as well as springy against the same time Bottom of the glass ceramic cooking surface 2 pressed.

Das vorzugsweise einstückig ausgebildete Federelement 8 bzw. 8' gemäß Fig. 2 oder 3 besteht dabei zweckmäßig aus einem federnden omegaförmigen Teil 9 und einem doppelschenkeligen wippenden Federteil 10. Beide Federteile 9 und 10 sind durch eine waagrechte Stützplatte 11 voneinander getrennt, wobei der doppelschenkelige Federteil 10 in eine waagrechte Fußplatte 12 übergeht.

Der omegaförmige Teil 9 des Federelementes 8 ist in zwei Einhängeschenkel 14 mit entsprechenden Einhängeösen 15 aufgeteilt. In der Fußplatte 12 des Federelementes 8 ist ein mit dem Boden der Muldenwanne 7 zusammenwirkende Einhänge- oder Rastöse 16 ausgebildet. Für diesen Zweck ist im Muldenwannen-Boden ein in Eingriff mit der Rastöse 16 bringbares Gegenstück in Form eines ausgebogenen Lappens 17 oder dergleichen vorgesehen.The preferably integrally formed spring element 8 or 8 ' As shown in FIG. 2 or 3 is expediently made of a resilient omega-shaped part 9 and a double-legged rocking Spring part 10. Both spring parts 9 and 10 are by a horizontal Support plate 11 separated from each other, wherein the double-legged Spring member 10 merges into a horizontal base plate 12. From the horizontal support plate 11 is a with the carrier shell bottom 4 'and optionally with the insulating body in Plug-in engageable tabs 13 bent out. The omega-shaped Part 9 of the spring element 8 is in two suspension legs 14 divided with corresponding suspension eyes 15. In the foot plate 12 of the spring element 8 is one with the bottom of the trough 7 cooperating suspension or detent 16 is formed. For this purpose is in the trough-bottom one in engagement with the latching eye 16 engageable counterpart in the form of a bent-out Lappens 17 or the like provided.

Wie die Fig. 1 zeigt, ist das Doppel-Federelement 8 mit seinen Einhängeschenkeln 14 und Einhängeösen 15 im Rand 18 der Muldenwanne 7 eingehängt, wobei die Trägerschale 4 auf der Feder-Stützplatte 11 abstützend aufliegt und der aus der Stützplatte 11 herausgebogene Lappen 13 den Trägerschalenboden 4' durchdringt und im Isolierkörper 5 endet. Mit seiner Fußplatte 16 ist das Doppel-Federelement 8, wie bereits ausgeführt, mit dem Wannenboden-Lappen 17 in Eingriff gebracht.As shown in FIG. 1, the double spring element 8 with its Einhänbringeln 14 and hooks 15 in the edge 18 of the trough 7 mounted, wherein the carrier shell 4 on the spring support plate 11 rests supporting and the out of the support plate 11 bent tabs 13 the carrier shell bottom 4 'penetrates and ends in the insulating body 5. With his foot plate 16 is the double-spring element 8, as already stated, with the Trough bottom flap 17 is brought into engagement.
