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 built-in hob 1 shown only partially in FIG. 1 a glass ceramic cooktop 2 with several heated cooking zones and a heating unit pressed against the bottom of the cooking surface 3 for each of the hot plates. The heating unit 3 exists from a carrier shell 4 made of sheet metal and an insulating body 5 with inserted heating conductor 6 (wire coil). All for the built-in hob 1 belonging carrier shells 4 are in a trough 7 used and there immovable in position to the respective hotplate fixed. To set the carrier shell 4 in the Trough pan 7 and for pressing the carrier shell 4 with the Heating conductor 6 against the underside of the glass ceramic cooktop 2 two special double spring elements 8 are provided, each are arranged opposite one another on the carrier shell 4. These spring elements are on the one hand in engagement with the Carrier shell 4 brought and on the other hand on the trough pan 7th hung or locked there, as explained in more detail later becomes. In this way, the heating unit 3 in both Position to the associated hotplate in the trough 7 is immovable set as well as resilient against the Bottom of the glass ceramic cooktop 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. Aus der waagrechten Stützplatte 11 ist ein mit dem Trägerschalenboden 4' und gegebenenfalls mit dem Isolierkörper in Steckeingriff bringbarer Lappen 13 herausgebogen. 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 one-piece spring element 8 or 8 ' 2 or 3 expediently consists of a resilient omega-shaped part 9 and a double-legged seesaw Spring part 10. Both spring parts 9 and 10 are by a horizontal Support plate 11 separated from each other, the double-legged Spring part 10 merges into a horizontal base plate 12. From the horizontal support plate 11 is one with the carrier shell bottom 4 'and optionally with the insulating body in Insertable flaps 13 bent out. The omega-shaped Part 9 of the spring element 8 is in two suspension legs 14 divided with corresponding hook eyes 15. In the footplate 12 of the spring element 8 is a with the bottom of the trough pan 7 cooperating hook-in or locking eye 16 formed. For this purpose there is an engagement in the trough bottom with the locking eyelet 16 counterpart in the form of a bent 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 Federstützplatte 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.1 shows the double spring element 8 with its Hanging legs 14 and 15 eyelets in the edge 18 of the trough 7 hung, the carrier shell 4 on the spring support plate 11 is supported and from the support plate 11 bent tabs 13 penetrate the carrier shell bottom 4 ' and ends in the insulating body 5. With its base plate 16 is the double spring element 8, as already stated, with the Tub bottom rag 17 engaged.
