Description

Die Erfindung betrifft ein Kochfeld, mit einer gehalterten Kochfeldplatte, nach dem Oberbegriff von Anspruch 1 oder Anspruch 12.The invention relates to a cooking hob, with a salaried hob plate, according to the preamble of claim 1 or claim 12.

Die gängigen derzeitigen Kochfelder weisen eine Glaskeramikplatte auf, unter der an den Kochstellen Heizkörper angeordnet sind. Die Heizkörper sind von einer Kochmulde umgeben, mit deren Rahmen das Kochfeld in Verbindung steht. Einige dieser Kochfelder weisen Halterungen auf, mit denen die Heizkörper an den Kochstellen fixiert und gegen die Kochfeldplatte gedrückt werden.The common current cooktops have a glass ceramic plate, are arranged under the radiators on the hobs. The radiators are surrounded by a cooktop, with the frame the hob is in communication. Some of these hobs have brackets that fix the radiators to the hobs and press them against the hob plate.

Ein Beispiel für eine derartige Halterung ist in der DE 198 54 228 A1 beschrieben. Der für die Montage des Kochfeldes vorgesehene Montagerahmen der Kochmulde weist in diesem Beispiel Halterungselemente aus Federstahl für die Heizkörper auf. Da eine sehr exakte Positionierung des Heizkörpers gegenüber der Kochfeldplatte notwendig ist, um die Funktionstüchtigkeit des Kochfeldes zu gewährleisten, ist hier ein sehr aufwändiges Halterungselement, mit einem Grundkörper mit Prägung und Positionshaken sowie Positionierarmen, die in den Heizkörper eingreifen, vorgesehen. Derartige Halteelemente sind sehr aufwändig und damit teuer in der Herstellung und erfordern eine sehr genaue Montage, was zu einer weiteren Erhöhung der Produktionskosten führt. Auch die Toleranzen bei der Herstellung von Heizkörper, Kochfeld und Mulde müssen sehr nieder angesetzt werden, wenn eine passgenaue Halterung der Heizkörper gegenüber dem Kochfeld gewährleistet werden soll.An example of such a holder is in DE 198 54 228 A1 described. The intended for the installation of the hob mounting frame of the hob has in this example mounting elements made of spring steel for the radiator. Since a very precise positioning of the radiator relative to the hob plate is necessary to ensure the functionality of the hob, here is a very complex support element, with a base body with embossing and position hooks and positioning, which engage in the radiator provided. Such holding elements are very complex and therefore expensive to produce and require a very accurate installation, which leads to a further increase in production costs. The tolerances in the production of radiator, hob and trough must be set very low, if a precisely fitting mounting of the radiator to the hob is to be ensured.

Eine andere Form der Halterung der Heizkörper ist in der DE 89 04 819 U1 beschrieben. Hier sind für die Halterung der Heizkörper Winkel an der Kochfeldplatte angeklebt, die mit federnden Heizkörperlaschen verschraubt werden, welche in die Heizkörper eingreifen. Vorteilhaft ist hier, dass die Halterung bereits an der Kochfeldplatte selbst angebracht ist, gegenüber der der Heizkörper zu positionieren ist. Damit kann die Positioniergenauigkeit schon deutlich einfacher gewährleistet werden, als wenn die Halterung indirekt über die Kochmulde realisiert ist. Dennoch ist auch diese Form der Halterung recht aufwändig in der Montage und erfordert relativ teuere stabile aber federnde Halteelemente, insbesondere Heizkörperlaschen, um die Heizkörper an allen Stellen plan an die Kochfeldplatte zu pressen. Insbesondere hat sich aber gezeigt, dass es auf Grund von Materialermüdungen zum Ablösen der Heizkörper von der Kochfeldplatte kommen kann. Somit ist auch die hier vorgeschlagene Lösung für eine Halterung eines Heizkörpers sehr teuer in Herstellung und Montage und außerdem nicht ausreichend zuverlässig.Another form of mounting the radiator is in the DE 89 04 819 U1 described. Here, angle brackets are glued to the hob plate for mounting the radiator, which are bolted with resilient radiator tabs, which engage in the radiator. It is advantageous here that the holder is already attached to the hob plate itself, opposite the radiator is to be positioned. Thus, the positioning accuracy can be ensured much easier than when the holder is realized indirectly via the hob. Nevertheless, this form of bracket is quite complex in the assembly and requires relatively expensive stable but resilient retaining elements, in particular radiator tabs to press the radiator in all places flat to the hob plate. In particular, it has been shown that due to material fatigue to detach the radiator from the hob plate can come. So here too proposed solution for a holder of a radiator very expensive to manufacture and assembly and also not sufficiently reliable.

Aus der EP 1 139 695 A2 ist ein Haushaltsgargerät mit einer Heizeinheit und einer Bedienvorrichtung bekannt, wobei die Heizeinheit unter einer Kochfeldplatte angeordnet ist. Darüber hinaus ist die Bedienvorrichtung an der Kochfeldplatte angeordnet.From the EP 1 139 695 A2 a household cooking appliance with a heating unit and an operating device is known, wherein the heating unit is arranged under a hob plate. In addition, the operating device is arranged on the hob plate.

Des Weiteren ist aus der EP 0 197 547 A2 ein Kochfeld gemäß dem Oberbegriff des Anspruchs 12 bekannt.Furthermore, from the EP 0 197 547 A2 a hob according to the preamble of claim 12 known.

Aufgabe der Erfindung ist es deshalb, eine Halterung für einen Heizkörper oder ein Gehäuse für eine elektronische Steuerung an einer Kochfeldplatte bereitzustellen, der einfach und kostengünstig herstellbar ist und eine einfache Montage des Heizkörpers erlaubt.The object of the invention is therefore to provide a holder for a radiator or a housing for an electronic control on a hob plate, which is simple and inexpensive to produce and allows easy installation of the radiator.

Gelöst wird diese Aufgabe gemäß der Erfindung, durch ein Kochfeld mit einer Halterung für einen Heizkörper mit den Merkmalen von Anspruch 12 und ein Kochfeld mit einer Halterung für ein Gehäuse für eine elektronische Steuerung mit den Merkmalen nach Anspruch 1.This object is achieved according to the invention, by a hob with a holder for a radiator with the features of claim 12 and a hob with a holder for a housing for an electronic control with the features of claim 1.

Erfindungsgemäß weist das Kochfeld nach Anspruch 12 Halteelemente zur Positionierung und Halterung der Heizkörper auf, welche an der Kochfeldplatte gelagert sind. Da eine genaue Positionierung der Heizköper gegenüber der Kochfeldplatte durch die Halteelemente bewirkt werden soll, gewährleistet eine Fixierung der Halteelemente für den Heizkörper, direkt an der Kochfeldplatte selbst, die einfachste, direkteste Realisierung. Diese, an der Kochfeldplatte verankerten Halteelemente sind so aufgebaut, dass sie sich seitlich am Heizkörper festkrallen und somit den Heizkörper zwischen den Halteelementen einklemmen. Dadurch, dass die Klemmung des Heizkörpers seitlich erfolgt, kann der Heizkörper auf einfachste Weise plan an die Kochfeldplatte gedrückt werden, ohne dass Anforderungen bezüglich der Höhe des Heizkörpers oder einer Befestigung desselben gegenüber den Halteelementen zu stellen sind. Eine Höhenanpassung der Halteelemente, abhängig von der Höhe des Heizkörpers, ist nicht notwendig. Indem der Heizkörper seitlich von Halteelementen festgeklemmt wird, ist die Montage des Heizkörpers in den Halteelementen extrem vereinfacht, da der Heizkörper nur in die Elemente hineingedrückt und nicht zusätzlich verschraubt oder anderweitig befestigt werden muss. Die elastischen, federnden Halteelemente zum seitlichen Festklemmen der Heizkörper können sehr kostengünstig zur Verfügung gestellt werden, da keinerlei Verschraubungen oder passgenaue Fixierungen oder Aussparungen notwendig sind. Da eine Verklemmung größtmögliche Toleranzen zulässt, wird auch die Herstellung von Heizkörper und Halterung kostengünstiger als bei herkömmlichen Halterungen.According to the invention, the hob according to claim 12 holding elements for positioning and holding the radiator, which are mounted on the hob plate. Since a precise positioning of the heating element relative to the hob plate is to be effected by the holding elements, a fixation of the holding elements for the radiator, directly to the hob plate itself, ensures the simplest, most direct implementation. These anchored to the hob plate holding elements are constructed so that they cling to the side of the radiator and thus pinch the radiator between the holding elements. Characterized in that the clamping of the radiator is made laterally, the radiator can be pressed flat on the hob plate in the simplest way without the requirements of the height of the radiator or a fixing of the same are to be set against the holding elements. A height adjustment of the holding elements, depending on the height of the radiator, is not necessary. By the radiator is clamped laterally by holding elements, the installation of the radiator in the holding elements is extremely simplified because the radiator pressed only in the elements and not additionally screwed or otherwise secured. The elastic, resilient retaining elements for lateral clamping of the radiator can be made available at very low cost, since no screwing or custom-fit fixations or recesses are necessary. Since jamming allows the highest possible tolerances, the production of radiator and bracket is also cheaper than with conventional brackets.

In einer vorteilhaften Ausführungsform der Erfindung sind die Halteelemente so ausgebildet, dass sie den Heizkörper, über eine reibschlüssige Verbindung, an der Kochfeldplatte fixieren. Hierdurch wird mittels eines einzigen Eingriffs gleichzeitig ein Fixieren des Heizkörpers in vertikaler und in horizontaler Richtung gewährleistet. Die reibschlüssige Verbindung der Halteelemente an der Seite des Heizkörpers kann in beliebiger Höhe erfolgen, sobald der Heizkörper direkt auf der Kochfeldplatte anliegt. Ein exaktes Zusammenwirken zwischen einem Fixierungselement an der Halterung und der entsprechenden Höhe des Heizkörpers ist für eine reibschlüssige Verbindung nicht notwendig, so dass diese besonders kostengünstig realisiert werden kann, da sie die größtmögliche Höhentoleranz zulässt.In an advantageous embodiment of the invention, the holding elements are designed so that they fix the radiator, via a frictional connection, to the hob plate. As a result, it is ensured by means of a single engagement simultaneously fixing the radiator in the vertical and horizontal directions. The frictional connection of the holding elements on the side of the radiator can be made at any height, as soon as the radiator directly on the hob plate is applied. An exact interaction between a fixing element on the holder and the corresponding height of the radiator is not necessary for a frictional connection, so that it can be realized particularly cost-effective, since it allows the greatest possible height tolerance.

In einer vorteilhaften Ausführungsform des Kochfeldes nach Anspruch 1 sind die Halteelemente aus Federstahl. Bei dem Kochfeld nach Anspruch 12 sind die Haltelemente aus Federstahl. Damit weisen sie eine intrinsische Federung auf, welche eine elastische Klemmung des Heizkörpers gewährleistet, ohne dass spezielle federnde Elemente vorgesehen werden müssen. Auch dies gewährleistet eine besonders kostengünstige Lösung für die Halterung.In an advantageous embodiment of the hob according to claim 1, the holding elements are made of spring steel. In the hob according to claim 12, the holding elements are made of spring steel. Thus, they have an intrinsic suspension, which ensures an elastic clamping of the radiator, without special resilient elements must be provided. This also ensures a particularly cost-effective solution for the holder.

Bei dem Kochfeld nach Anspruch 12 sind die Halteelemente aus härterem Material geformt als der Heizkörper selbst. In einer weiteren vorteilhaften Ausführungsform des Kochfeldes nach Anspruch 12 ist ein, in den Heizkörper eingreifender, scharfkantiger Vorsprung eines Halteelements, aus härterem Material geformt als der Heizkörper selbst. Das härtere Material des Vorsprungs krallt sich dann in das weiche Material des Heizkörpers ein, sobald der Heizkörper zwischen den Halteelementen festgedrückt wird. Hierdurch entsteht gewissermaßen von selbst eine feste Verbindung zwischen den Halteelementen und dem Heizkörper, ein Verrutschen des Heizkörpers ist praktisch ausgeschlossen, ohne dass wie bisher ineinander greifende, passgenaue Sicherungselemente notwendig wären.In the hob according to claim 12, the holding elements of harder material are formed as the radiator itself. In a further advantageous embodiment of the hob according to claim 12 is a, engaging in the radiator, sharp edge projection of a holding element, formed of a harder material than the radiator itself. The harder material of the projection then clings into the soft material of the radiator, as soon as the radiator is pressed between the holding elements. This results in a sense of itself a firm connection between the holding elements and the radiator, slipping of the radiator is practically impossible without as previously interlocking, custom-fit security elements would be necessary.

In einer weiteren vorteilhaften Ausgestaltung des erfindungsgemäßen Kochfeldes sind pro Heizkörper drei Halteelemente vorgesehen, welche den Heizkörper seitlich festklemmen. Drei Elemente bewirken eine exakte Fixierung, bei größtmöglicher Toleranz, der zu fixierenden Elemente.In a further advantageous embodiment of the hob according to the invention three retaining elements are provided per radiator, which laterally clamp the radiator. Three elements cause an exact fixation, with the greatest possible tolerance, of the elements to be fixed.

Eine weitere vorteilhafte Ausführungsform des Kochfeldes sieht Halteelemente vor, welche im Eintrittsbereich des Heizkörpers abgeschrägt sind. In der einfachsten Ausführungsform der Halteelemente sind dies Bleche aus Federstahl, welche im Eintrittsbereich des Heizkörpers von diesem weg gebogen sind. Die Eintrittsschräge der Halteelemente ermöglicht eine besonders einfache Montage des Heizkörpers und somit eine kostengünstige Lösung für das Kochfeld.A further advantageous embodiment of the hob provides holding elements, which are bevelled in the inlet region of the radiator. In the simplest embodiment of the holding elements, these are sheets of spring steel, which are bent in the inlet region of the radiator away from this. The entry slope of the holding elements allows a particularly simple installation of the radiator and thus a cost-effective solution for the hob.

In einer weiteren vorteilhaften Ausführungsform des Kochfeldes nach Anspruch 12 ist am Kochfeldboden, als zusätzliches, weiteres Halteelement, ein federnder Vorsprung vorgesehen, der den Heizkörper von unten gegen die Kochfeldplatte drückt. Auch dieser Vorsprung im Kochfeldboden kann einfach aus einem elastischen, federnden Blech gestaltet sein, es sind keine besonderen Anforderung an Toleranzen, bezüglich des Heizkörpers, zu stellen.In a further advantageous embodiment of the hob according to claim 12, a resilient projection is provided on the hob base, as an additional, further holding element, which presses the heater from below against the hob plate. Also this projection in the hob soil can simply from a elastic, resilient sheet be designed, there are no special requirements for tolerances, with respect to the radiator, to ask.

Die Kombination aus reibschlüssiger, seitlicher Fixierung des Heizkörpers und horizontaler Positionierung und vertikaler Fixierung, mittels eines Vorsprungs im Kochfeldboden, ermöglicht eine sehr einfache Gestaltung der Halteelemente, eine einfache und schnelle Montage des Kochfeldes und einen Gesamtaufbau, der keine großen Toleranzanforderungen stellt. Die reibschlüssige Verbindung der seitlichen Halteelemente, welche an der Kochfeldplatte angeordnet sind, ermöglicht außerdem eine einfache Vormontage und verhindert ein seitliches Versetzen des Heizkörpers, ohne dass eine passgenaue Befestigung, welche teuer und aufwändig in der Montage wäre, notwendig ist. Die Absicherung dieser einfachen Halterung erfolgt ebenfalls auf einfache Weise, mittels des Vorsprungs im Kochfeldboden, an den keine Anforderungen, bezüglich der genauen Position, zu stellen sind, so dass auch dieser kostengünstig zur Verfügung gestellt werden kann.The combination of frictional, lateral fixation of the radiator and horizontal positioning and vertical fixation, by means of a projection in the hob base, allows a very simple design of the holding elements, a simple and quick installation of the hob and a total structure that does not require large tolerance. The frictional connection of the lateral holding elements, which are arranged on the hob plate, also allows easy pre-assembly and prevents lateral displacement of the radiator, without a precise fitting, which would be expensive and expensive to install, is necessary. The protection of this simple holder also takes place in a simple manner, by means of the projection in the hob base to which no requirements, with respect to the exact position, are to be provided, so that this can be made available at low cost.

Fig. 1 zeigt ein Kochfeld gemäß dem ersten Ausführungsbeispiel mit einer Kochfeldplatte bzw. einer Glaskeramikplatte 1. Auf der Kochfeldplatte 1 ist als ein Bauteil ein Heizkörper 2 aufgesetzt, welcher hier ausschnittsweise dargestellt ist. Der Heizkörper ist als Strahlungsheizkörper mit einem Heizkörpertopf ausgebildet. In dem Heizkörpertopf ist ein Heizband angeordnet, das auf einer Isolierung gebettet ist und Wärmestrahlung an ein auf der Glaskeramikplatte gestelltes Gargutbehältnis abgibt. Der Heizkörper 2 wird mittels eines Befestigungswinkels 3 an die Kochfeldplatte 1 gedrückt. Der Befestigungswinkel 3 ist an einer Klebestelle 4 fest mit der Kochfeldplatte verbunden. Der Befestigungswinkel 3 schmiegt sich an die Seite des Heizkörpers 2 und weist einen Vorsprung 5 auf, der in eine Seitenwand des Heizkörpers 2 eingreift. Der Befestigungswinkel ist an seinem, von der Kochfeldplatte abgewandten Ende, vom Heizkörper 2 weg gebogen, so dass er eine Einführschräge 6 ausbildet, die ein einfaches Einführen des Heizkörpers in den Befestigungswinkel 3 ermöglicht, ohne dass die Gefahr der Beschädigung des Heizkörpers gegeben ist. Ein Kochfeldboden 7 begrenzt zusammen mit der Glaskeramikplatte 1 einen Innenraum des Kochfelds. Im Kochfeldboden 7 ist im Bereich des Bodens des Heizkörpers 2 vorsprungartig eine Ausbuchtung 8 ausgestülpt, die den Heizkörper 2 gegen die Kochfeldplatte 1 drückt. Fig. 1 shows a hob according to the first embodiment with a hob plate or a glass ceramic plate 1. On the hob plate 1 is a radiator 2 is placed as a component, which is shown here in fragmentary form. The radiator is designed as a radiant heater with a radiator pot. In the radiator pot, a heating tape is arranged, which is embedded on an insulation and emits heat radiation to a provided on the glass ceramic plate Gargutbehältnis. The radiator 2 is pressed by means of a mounting bracket 3 to the hob plate 1. The mounting bracket 3 is connected to a splice 4 fixed to the hob plate. The mounting bracket 3 nestles against the side of the radiator 2 and has a projection 5, which in a side wall of the Radiator 2 engages. The mounting bracket is bent at its, remote from the hob plate end of the radiator 2 away, so that it forms an insertion bevel 6, which allows easy insertion of the radiator in the mounting bracket 3, without the risk of damage to the radiator is given. A hob base 7, together with the glass ceramic plate 1 defines an interior of the hob. In the hob base 7, a protrusion 8 is everted in the region of the bottom of the radiator 2, which presses the radiator 2 against the hob plate 1.

Fig. 2 zeigt eine perspektivische Detailansicht des Befestigungswinkels, der die Seitenwand des Heizkörpers 2 festklemmt. Die perspektivische Ansicht verdeutlicht noch einmal den Aufbau des, als Halteelement verwendeten Befestigungswinkel 3, für den Heizkörper 2. Der Befestigungswinkel 3 hat im Eintrittsbereich des Heizkörpers 2 eine Einführschräge 6, die dem Heizkörper 2 ein einfaches Eintreten in die Halterung ermöglicht. Unterhalb der Eintrittsschräge 6 ist das Federblech so nach Innen gebogen, dass sich ein Vorsprung 5 ergibt, der eine scharfe Schnittkante ausbildet, welche in einem Linienkontakt mit der Seitenwand ist, und sich in dem Blech des Heizkörpers 2 festkrallt. Ein Schenkel 4 des Befestigungswinkels 3 ist dabei so auf die Kochfeldplatte geklebt, dass eine scharfe Kante des Vorsprungs 5 gegen die Seitenwand des Heizkörpers 2 drückt. Fig. 2 shows a perspective detail view of the mounting bracket, which clamps the side wall of the radiator 2. The perspective view again illustrates the structure of the mounting bracket 3 used as a holding element for the radiator 2. The mounting bracket 3 has in the inlet region of the radiator 2 an insertion bevel 6, which allows the radiator 2 easy entry into the holder. Below the entry slope 6, the spring plate is bent inwardly so that a projection 5 results, which forms a sharp cutting edge, which is in line contact with the side wall, and claws in the sheet of the radiator 2. A leg 4 of the mounting bracket 3 is glued to the hob plate that a sharp edge of the projection 5 presses against the side wall of the radiator 2.

Wie in Fig. 3 im Überblick dargestellt ist, sind rund um den Heizkörper 2 drei derartige Befestigungswinkel 3 angeordnet, die jeweils mit der Kochfeldplatte 1 verklebt sind. Die Befestigungswinkel 3 sind in einem Dreieck um den Heizkörper 2 verteilt, so dass sie den Heizkörper 2 gegen eine seitliche Verschiebung sichern. Die Vorsprünge 5, die sich seitlich in dem Heizkörper 2 festkrallen, halten den Heizkörper, zumindest vorläufig, fest, so dass das Kochfeld auf dem Kochfeldboden befestigt werden kann. Die Ausbuchtung 8 im Kochfeldboden presst den Heizkörper 2 schließlich gegen die Kochfeldplatte 1, so dass der Heizkörper 2 schließlich an seiner prädestinierten Kochstelle fest gehaltert ist. Diese Halterung wird durch einfache Klemmelemente realisiert, welche billig und einfach herstellbar sind und eine einfache und schnelle Vormontage und Montage erlauben.As in Fig. 3 is shown in overview, two such mounting bracket 3 are arranged around the radiator 2, which are glued to the hob plate 1. The mounting brackets 3 are distributed in a triangle around the radiator 2, so that they secure the radiator 2 against lateral displacement. The projections 5, which cling laterally in the radiator 2, hold the radiator, at least provisionally, firmly, so that the hob can be mounted on the hob bottom. The bulge 8 in the hob bottom pressed the radiator 2 finally against the hob plate 1, so that the radiator 2 is finally firmly held at its predestined cooking. This holder is realized by simple clamping elements, which are cheap and easy to manufacture and allow easy and quick pre-assembly and assembly.

Fig. 4 zeigt ein Kochfeld gemäß dem zweiten Ausführungsbeispiel. Im Unterschied zu dem ersten Ausführungsbeispiel weist die Seitenwand des Heizkörpers eine Vertiefung 9 auf. In die Vertiefung 9 ist der Vorsprung 5 des Befestigungswinkels 3 eingerastet. Demzufolge ist in der Fig. 4 der Heizkörper 2 über die Befestigungswinkel 3 nicht nur festgeklemmt, sondern rastet der Vorsprung 5 des Befestigungswinkels 3 auch zusätzlich in die Vertiefung 9 der Seitenwand des Heizkörpers 2 ein. Vorliegend kann auch auf die Klemmverbindung zwischen dem Befestigungswinkel 3 und dem Heizkörper verzichtet werden. Fig. 4 shows a hob according to the second embodiment. In contrast to the first embodiment, the side wall of the radiator has a recess 9. In the recess 9 of the projection 5 of the mounting bracket 3 is engaged. Consequently, in the Fig. 4 the radiator 2 not only clamped on the mounting bracket 3, but snaps the Projection 5 of the mounting bracket 3 also in addition to the recess 9 of the side wall of the radiator 2 a. In the present case can be dispensed with the clamping connection between the mounting bracket 3 and the radiator.

In der Fig. 5 ist gemäß dem dritten Ausführungsbeispiel kein Heizkörper 2, sondern ein elektronisches Bauteil 11, etwa ein Anzeigenelement, mit seinem Gehäuse 13 an der Unterseite der Glaskeramikplatte 1 gehaltert. Das elektronische Bauteil 11 ist an seiner Gehäuseseitenwand mit einer Rastschulter 15 ausgebildet. In der Fig. 5 hintergreift der Vorsprung 5 des Befestigungswinkels 3 die an der Gehäuseseitenwand gebildete Rastschulter 15.In the Fig. 5 is according to the third embodiment, not a radiator 2, but an electronic component 11, such as a display element, supported with its housing 13 on the underside of the glass ceramic plate 1. The electronic component 11 is formed on its housing side wall with a latching shoulder 15. In the Fig. 5 behind the projection 5 of the mounting bracket 3 engages the latching shoulder 15 formed on the housing side wall.
