Demgemäß wird eine Kochmulde mit einem Gasbrenner und zumindest einer Positioniereinrichtung zum Positionieren des Gasbrenners in oder an der Kochmulde, wobei die Positioniereinrichtung mindestens einen Eingriffsabschnitt umfasst, der dazu eingerichtet ist, in einen Durchbruch einer Bodenwanne der Kochmulde formschlüssig einzugreifen, vorgeschlagen. Dabei ist die Positioniereinrichtung aus einem Kunststoffmaterial gefertigt. Die Positioniereinrichtung weist mindestens einen Haltestift auf, der dazu eingerichtet ist, in ein Brennergehäuse des Gasbrenners formschlüssig einzugreifen.Against this background, an object of the present invention is to provide an improved cooktop. Accordingly, a cooktop with a gas burner and at least one positioning device for positioning the gas burner in or on the cooktop, wherein the positioning means comprises at least one engagement portion which is adapted to engage positively in a breakthrough of a bottom trough of the cooktop proposed. The positioning device is made of a plastic material. The positioning device has at least one retaining pin, which is adapted to engage positively in a burner housing of the gas burner.

Dadurch, dass die Positioniereinrichtung dazu eingerichtet ist, in den Durchbruch der Bodenwanne formschlüssig einzugreifen, kann diese ohne zusätzliche Hilfsmittel wie beispielsweise Schrauben an der Bodenwanne befestigt werden. Die Fertigung der Positioniereinrichtung aus einem Kunststoffmaterial ermöglicht dessen kostengünstige Herstellung in großen Stückzahlen, z.B. in einem Kunststoffspritzgussverfahren. Beispielsweise ist die Positioniereinrichtung aus einem hitzebeständigen Kunststoffmaterial wie beispielsweise Polyetheretherketon gefertigt. Die Positioniereinrichtung kann aus einem faserverstärkten, insbesondere glasfaserverstärkten, Kunststoffmaterial gefertigt sein.Characterized in that the positioning device is adapted to intervene positively in the opening of the floor pan, it can be fixed without additional aids such as screws on the floor pan. The manufacture of the positioning device from a plastic material enables its cost-effective production in large numbers, e.g. in a plastic injection molding process. For example, the positioning device is made of a heat-resistant plastic material such as polyetheretherketone. The positioning device can be made of a fiber-reinforced, in particular glass fiber reinforced, plastic material.

An dem Brennergehäuse sind vorzugsweise Aufnahmeabschnitte vorgesehen, in die der Haltestift eingreift.

Wie die Fig. 3 und 4 zeigen, weist der Eingriffsabschnitt 8 beispielsweise zwei einander gegenüberliegend angeordnete elastisch verformbare Eingriffsarme 12, 13 auf. Die Eingriffsarme 12, 13 sind keilförmig ausgebildet. Insbesondere sind die Eingriffsarme 12, 13 als Schnapphaken ausgebildet. Beim Eindrücken des Eingriffsabschnitts 8 in den Durchbruch 6 der Bodenwanne 3 werden die Eingriffsarme 12, 13 elastisch verformt und schnappen hinter dem Durchbruch 6 ein. Insbesondere ist hierzu an den Eingriffsarmen 12, 13 jeweils eine Einführschräge 14 vorgesehen.Each engagement section 8 preferably has at least one elastically deformable engagement arm 12, 13. As the 3 and 4 show, the engagement portion 8, for example, two oppositely arranged elastically deformable engagement arms 12, 13. The engagement arms 12, 13 are wedge-shaped. In particular, the engagement arms 12, 13 are designed as snap hooks. When pressing the engaging portion 8 in the opening 6 of the bottom tray 3, the engaging arms 12, 13 are elastically deformed and snap behind the opening 6 a. In particular, an insertion bevel 14 is provided on the engagement arms 12, 13 for this purpose.

Wie die Fig. 1 weiterhin zeigt, kann an jedem Eingriffsabschnitt 8 eine Federeinrichtung 15 vorgesehen sein, die vorzugsweise materialeinstückig mit dem Eingriffsabschnitt 8 ausgebildet ist. Die Federeinrichtung 15 ist beispielsweise als Blattfeder ausgebildet. Die Federeinrichtung 15 spannt die Positioniereinrichtung 7 gegen die Bodenwanne 3 vor. Hierdurch wird ein Verrutschen oder Wackeln der Positioniereinrichtung 7 verhindert.As the Fig. 1 Furthermore, a spring means 15 may be provided on each engaging portion 8, which is preferably formed integrally with the engaging portion 8 material. The spring device 15 is formed for example as a leaf spring. The spring device 15 biases the positioning device 7 against the bottom pan 3. As a result, slipping or wobbling of the positioning device 7 is prevented.

Beispielsweise weist jeder Eingriffsabschnitt 8 drei oder vier Eingriffsarme 12, 13 auf, von denen in der Fig. 8 lediglich zwei mit einem Bezugszeichen versehen sind. Die Eingriffsarme 12, 13 weisen vorzugsweise keine Einführschrägen auf, sondern werden durch Eindrücken des Betätigungsstifts 16 derart verformt, dass diese den Durchbruch 6 hintergreifen.The FIGS. 7 and 8 each show in a schematic perspective view of another embodiment of a positioning device 7. The positioning device 7 according to the FIGS. 7 and 8 differs from the previously described embodiments of the positioning device 7 in that it comprises at least one actuating pin 16 which is adapted to deform the at least one engagement portion 8 so that it engages behind the opening 6. For example, each engaging portion 8 has three or four engaging arms 12, 13, of which in the Fig. 8 only two are provided with a reference numeral. The engagement arms 12, 13 preferably have no insertion bevels, but are deformed by pressing the actuating pin 16 such that they engage behind the opening 6.

Die Fig. 9 und 10 zeigen jeweils in einer schematischen perspektivischen Ansicht eine weitere Ausführungsform einer Positioniereinrichtung 7. Die Positioniereinrichtung 7 gemäß der Fig. 9 und 10 unterscheidet sich von der Positioniereinrichtung 7 gemäß der Fig. 7 und 8 dadurch, dass die Positioniereinrichtung 7 keinen Basisabschnitt 9 aufweist. An dem Haltestift 10 ist unterseitig ein Betätigungsstift 16 vorgesehen, der dazu eingerichtet ist, die Eingriffsarme 12, 13 beim Herunterdrücken des Haltestifts 10 so zu verformen, dass diese den Durchbruch 6 der Bodenwanne 3 hintergreifen.The FIGS. 9 and 10 each show in a schematic perspective view of another embodiment of a positioning device 7.
