Eine Kochstelle, insbesondere eine Gaskochstelle, kann mehrere Gasbrenner aufweisen, die an einem sogenannten Top Sheet bzw. einer Deckplatte der Kochstelle befestigt sind. Die Deckplatte kann beispielsweise aus Glaskeramik oder aus Metall gefertigt sein. Deckplatten aus Metall werden üblicherweise tiefgezogen, das heißt, sie werden mittels einer Presse in einem Tiefziehwerkzeug dreidimensional verformt.A hotplate, in particular a gas hotplate, can have several gas burners which are attached to a so-called top sheet or a cover plate of the hotplate. The cover plate can be made of glass ceramic or metal, for example. Cover plates made of metal are usually deep-drawn, that is, they are three-dimensionally deformed by means of a press in a deep-drawing tool.

An Rändern der Herdmulde sind Winkelstücke fest mit dieser verbunden.The DE 1 454 333 A1 describes a worktop in which a hob is molded directly. At the edges of the hob, elbows are firmly connected to it.

Die DE 297 22 313 U1 beschreibt eine Muldenplatte mit einem umlaufenden Umfangrahmen. Eine Versteifung der Muldenplatte wird durch direkt an die Muldenplatte angeformte rippenförmige Abschnitte erreicht.The DE 297 22 313 U1 describes a trough plate with a peripheral frame. A stiffening of the trough plate is achieved by means of rib-shaped sections molded directly onto the trough plate.

Die EP 2 202 464 A2 beschreibt ein Kochfeld, an dem unterseitig eine Leiste zum Versteifen des Kochfelds vorgesehen ist.The EP 2 202 464 A2 describes a hob, on the underside of which a bar is provided for stiffening the hob.

Die EP 0 856 702 A1 beschreibt ein Gaskochgerät mit einer Glas- oder Glaskeramikplatte.The EP 0 856 702 A1 describes a gas cooker with a glass or glass ceramic plate.

Vor diesem Hintergrund besteht eine Aufgabe der vorliegenden Erfindung darin, eine verbesserte Deckplatte zur Verfügung zu stellen.Against this background, an object of the present invention is to provide an improved cover plate.

Demgemäß wird eine Deckplatte für eine Kochstelle mit einem ebenen flächigen Basisabschnitt, der eine Ebene aufspannt, die durch eine erste Raumrichtung und eine sich von der ersten Raumrichtung unterscheidende zweite Raumrichtung definiert ist, zwei Versteifungsabschnitten, die aus dem ebenen flächigen Basisabschnitt herausgebogen sind und die an zwei einander gegenüberliegenden Randabschnitten des Basisabschnitts vorgesehen sind, wobei der Basisabschnitt und die Versteifungsabschnitte aus einem umgeformten ebenen flächigen Blechzuschnitt gebildet sind, und einem von dem Basisabschnitt getrennten und an diesem angebrachten Versteifungselement vorgeschlagen, wobei der Versteifungsabschnitt und das Versteifungselement so angeordnet sind, dass die Deckplatte mit Hilfe des Versteifungsabschnitts in der ersten Raumrichtung und mit Hilfe des Versteifungselements in der sich von der ersten Raumrichtung unterscheidenden zweiten Raumrichtung derart versteift ist, dass der Versteifungsabschnitt eine Biegung der Deckplatte um die erste Raumrichtung als Biegeachse verhindert und dass das Versteifungselement eine Biegung der Deckplatte um die zweite Raumrichtung als Biegeachse verhindert, wobei der Versteifungsabschnitt an einem Randabschnitt des Basisabschnitts vorgesehen ist und wobei das Versteifungselement an einer senkrecht zu dem Randabschnitt angeordneten Schnittkante des Basisabschnitts angebracht ist.Accordingly, a cover plate for a hotplate with a flat planar base section that spans a plane that is defined by a first spatial direction and a second spatial direction that differs from the first spatial direction, two stiffening sections that are bent out of the flat planar base section and that on two mutually opposite edge sections of the base section are provided, the base section and the stiffening sections being formed from a formed flat sheet metal blank, and one from the base section separate and attached to this stiffening element, wherein the stiffening section and the stiffening element are arranged such that the cover plate is stiffened with the aid of the stiffening section in the first spatial direction and with the aid of the stiffening element in the second spatial direction, which differs from the first spatial direction, such that the Stiffening section prevents bending of the cover plate around the first spatial direction as a bending axis and that the stiffening element prevents bending of the covering plate around the second spatial direction as a bending axis, the stiffening section being provided on an edge section of the base section and the stiffening element on a cutting edge arranged perpendicular to the edge section of the base section is attached.

Durch das nachträgliche Anbringen des Versteifungselements kann die Deckplatte in einem im Vergleich zum Tiefziehen einfacheren Fertigungsprozess wie in einem Biege-, Roll- und/oder Walzprozess hergestellt werden. Hierdurch kann auf kosten- und wartungsintensive Tiefziehwerkzeuge verzichtet werden. Weiterhin ist durch den Verzicht auf einen Tiefziehprozess eine einfachere Variantenbildung bei der Herstellung der Deckplatte möglich.By subsequently attaching the stiffening element, the cover plate can be produced in a simpler manufacturing process than in deep drawing, such as in a bending, rolling and / or rolling process. This means that costly and maintenance-intensive deep-drawing tools can be dispensed with. Furthermore, by dispensing with a deep-drawing process, a simpler variant formation in the manufacture of the cover plate is possible.

Die erste Raumrichtung und die zweite Raumrichtung sind vorzugsweise senkrecht zueinander positioniert. Der Versteifungsabschnitt ist insbesondere dazu eingerichtet, die Deckplatte in der ersten Raumrichtung zu versteifen. Das heißt, eine Biegung der Deckplatte um die erste Raumrichtung als Biegeachse wird mit Hilfe des Versteifungsabschnitts verhindert. Das Versteifungselement ist insbesondere dazu eingerichtet, die Deckplatte in der zweiten Raumrichtung zu versteifen. Das heißt, eine Biegung der Deckplatte um die zweite Raumrichtung als Biegeachse wird mit Hilfe des Versteifungselements verhindert. Der Versteifungsabschnitt verhindert insbesondere eine Verbiegung der Deckplatte senkrecht zu dem Versteifungsabschnitt. Vorzugsweise sind der Versteifungsabschnitt und das Versteifungselement senkrecht zueinander orientiert. Unter "senkrecht" oder einem Winkel von 90° ist vorliegend ein Winkel von bevorzugt 90° ± 10°, weiter bevorzugt von 90° ± 5°, weiter bevorzugt von 90° ± 1°, weiter bevorzugt von genau 90° zu verstehen.The first spatial direction and the second spatial direction are preferably positioned perpendicular to one another. The stiffening section is in particular set up to stiffen the cover plate in the first spatial direction. This means that the cover plate is prevented from bending about the first spatial direction as a bending axis with the aid of the stiffening section. The stiffening element is in particular set up to stiffen the cover plate in the second spatial direction. This means that the cover plate is prevented from bending about the second spatial direction as a bending axis with the aid of the stiffening element. The stiffening section in particular prevents bending of the cover plate perpendicular to the stiffening section. The stiffening section and the stiffening element are preferably oriented perpendicular to one another. "Vertical" or an angle of 90 ° in the present case means an angle of preferably 90 ° ± 10 °, more preferably 90 ° ± 5 °, more preferably 90 ° ± 1 °, more preferably exactly 90 °.

Der Versteifungsabschnitt ist an einem Randabschnitt des Basisabschnitts vorgesehen.The stiffening section is provided on an edge section of the base section.

Der Versteifungsabschnitt ist vorzugsweise in einem Winkel von 90° relativ zu dem Basisabschnitt verformt.The stiffening section is preferably deformed at an angle of 90 ° relative to the base section.

Die Deckplatte weist zwei Versteifungsabschnitte auf, die an einander gegenüberliegenden Randabschnitten des Basisabschnitts vorgesehen sind.The cover plate has two stiffening sections which are provided on opposite edge sections of the base section.

Die Deckplatte kann auch mehr als zwei Versteifungsabschnitte aufweisen. Die Versteifungsabschnitte können auch mittig an dem Basisabschnitt vorgesehen sein. Mindestens weist die Deckplatte einen Versteifungsabschnitt auf.The cover plate can also have more than two stiffening sections. The stiffening sections can also be provided centrally on the base section. At least the cover plate has a stiffening section.

Das Versteifungselement ist an einer senkrecht zu den Randabschnitten angeordneten Schnittkante des Basisabschnitts angebracht.The stiffening element is attached to a cut edge of the base section arranged perpendicular to the edge sections.

Hierdurch wird die scharfkantige Schnittkante abgedeckt, wodurch eine wirksame Kantenabdeckung erreicht wird. Dies reduziert die Verletzungsgefahr.As a result, the sharp-edged cut edge is covered, whereby effective edge coverage is achieved. This reduces the risk of injury.

Gemäß einer weiteren Ausführungsform ist das Versteifungselement auf den Basisabschnitt aufgesteckt, mit diesem verklebt, verschweißt, vernietet, verschraubt und/oder verclipst.According to a further embodiment, the stiffening element is plugged onto the base section, glued to it, welded, riveted, screwed and / or clipped.

Das Versteifungselement kann beispielsweise aus Metall oder aus Kunststoff gefertigt sein. Insbesondere kann das Versteifungselement ein Kunststoffspritzgussbauteil sein.The stiffening element can be made of metal or plastic, for example. In particular, the stiffening element can be a plastic injection molded component.

Gemäß einer weiteren Ausführungsform ist der Basisabschnitt mit Hilfe eines Biege-, Roll- und/oder Walzverfahrens umgeformt.According to a further embodiment, the base section is formed using a bending, rolling and / or rolling process.

Hierdurch kann die Deckplatte kostengünstig hergestellt werden. Insbesondere sind an dem ebenen flächigen Basisabschnitt entsprechende Bearbeitungsspuren zu erkennen.As a result, the cover plate can be produced inexpensively. In particular, corresponding processing traces can be seen on the flat, flat base section.

Gemäß einer weiteren Ausführungsform bildet das Versteifungselement einen seitlichen Abschluss der Deckplatte.According to a further embodiment, the stiffening element forms a lateral end of the cover plate.

Insbesondere ist das Versteifungselement zu sehen.In particular, the stiffening element can be seen.

Ferner wird ein Standherd mit einer derartigen Deckplatte vorgeschlagen, wobei das Versteifungselement Teil eines Korpus des Standherds ist.Furthermore, a standing stove with such a cover plate is proposed, the stiffening element being part of a body of the standing stove.

Hierdurch kann auf ein zusätzliches Bauteil in Form des Versteifungselements verzichtet werden. Das Versteifungselement kann einstückig, insbesondere materialeinstückig, mit einer Seitenwand des Korpus ausgebildet sein. Die Seitenwand kann aus einem Stahlblech gefertigt sein. Der Korpus kann ein Gehäuse des Standherds sein. Neben der Seitenwand können auch andere Elemente des Standherds, wie beispielsweise ein an der Seitenwand angebrachtes Versteifungsmittel, zur Versteifung und/oder unterseitigen Abstützung der Deckplatte dienen. Der Standherd kann die Kochstelle umfassen.As a result, an additional component in the form of the stiffening element can be dispensed with. The stiffening element can be formed in one piece, in particular in one piece of material, with a side wall of the body. The side wall can be made of sheet steel. The body can be a housing for the range cooker. In addition to the side wall, other elements of the range cooker, such as a stiffening means attached to the side wall, can also serve to stiffen and / or support the cover plate on the underside. The free-standing cooker can include the hob.

In den Figuren sind gleiche oder funktionsgleiche Elemente mit denselben Bezugszeichen versehen worden, sofern nichts anderes angegeben ist.In the figures, elements that are the same or have the same function have been provided with the same reference symbols, unless stated otherwise.

Die Fig. 1 zeigt eine schematische perspektivische Ansicht einer Kochstelle 1. Die Kochstelle 1 ist vorzugsweise eine Gaskochstelle. Die Kochstelle 1 kann mehrere Gasbrenner 2 aufweisen. Die Anzahl der Gasbrenner 2 ist beliebig. Wie die Fig. 1 zeigt, kann die Kochstelle 1 vier Gasbrenner 2 aufweisen.The Fig. 1 shows a schematic perspective view of a hotplate 1. The hotplate 1 is preferably a gas hotplate. The hotplate 1 can have several gas burners 2. The number of gas burners 2 is arbitrary. As the Fig. 1 shows, the hotplate 1 can have four gas burners 2.

Die Kochstelle 1 umfasst weiterhin ein sogenanntes Top Sheet bzw. eine Deckplatte 3. Die Deckplatte 3 kann zumindest teilweise aus einem Metallblech gefertigt sein. Die Gasbrenner 2 sind so angeordnet, dass ein Brenneroberteil 4 des jeweiligen Gasbrenners 2 über die Deckplatte 3 hinausragt. Ein nicht gezeigtes Brennerunterteil ist unter der Deckplatte 3 angeordnet. Insbesondere ist das Brennerunterteil mit der Deckplatte 3 verbunden, vorzugsweise verschraubt.The hotplate 1 further comprises a so-called top sheet or a cover plate 3. The cover plate 3 can be made at least partially from a metal sheet. The gas burners 2 are arranged such that an upper burner part 4 of the respective gas burner 2 projects beyond the cover plate 3. A burner lower part, not shown, is arranged under the cover plate 3. In particular, the burner lower part is connected to the cover plate 3, preferably screwed.

Die Deckplatte 3 umfasst einen ebenen flächigen Basisabschnitt 5, der eine Ebene E aufspannen kann. Der ebene flächige Basisabschnitt 5 kann beispielsweise gekrümmt sein. Die Krümmung kann geringfügig sein. Die Ebene E ist durch zwei Raumrichtungen, nämlich eine erste oder x-Richtung x und eine zweite oder y-Richtung y definiert. Die Deckplatte 3 umfasst weiterhin zumindest einen Versteifungsabschnitt 6, der aus der dem ebenen flächigen Basisabschnitt 5 herausgebogen ist. Beispielsweise kann der Versteifungsabschnitt 6 um einen Winkel von 90° aus dem Basisabschnitt 5 herausgebogen sein. Wie die Fig. 1 zeigt, kann die Deckplatte 3 zwei derartige Versteifungsabschnitte 6 aufweisen, die jeweils an Randabschnitten 7, 8 der Deckplatte 3 vorgesehen sind. Die flächigen Randabschnitte 7, 8 sind parallel zu der Ebene E bzw. zu dem Basisabschnitt 5 angeordnet. An dem Randabschnitt 7 können Belüftungsöffnungen 9 vorgesehen sein, die zum Zuführen von Primärluft L zu den Gasbrennern 2 geeignet sind. Anstelle der Gasbrenner 2 können auch sogenannte elektrische Massekochplatten vorgesehen sein.The cover plate 3 comprises a flat, flat base section 5, which can span a plane E. The flat flat base section 5 can be curved, for example. The curvature can be slight. The plane E is defined by two spatial directions, namely a first or x direction x and a second or y direction y. The cover plate 3 further comprises at least one stiffening section 6, which is bent out of the flat flat base section 5. For example, the stiffening section 6 can be bent out of the base section 5 by an angle of 90 °. As the Fig. 1 shows, the cover plate 3 can have two such stiffening sections 6, which are each provided on edge sections 7, 8 of the cover plate 3. The flat edge sections 7, 8 are arranged parallel to the plane E or to the base section 5. Ventilation openings 9 can be provided on the edge section 7, which are suitable for supplying primary air L to the gas burners 2. Instead of the gas burners 2, so-called electric hot plates can also be provided.

Der flächige Basisabschnitt 5 mit den Versteifungsabschnitten 6 und den Randabschnitten 7, 8 ist vorzugsweise in einem Biege-, Walz- und/oder Rollprozess gefertigt. Um die Gasbrenner 2 herum umlaufend sind sogenannte Dome 10 vorgesehen, die beispielsweise ebenfalls in einem Walzprozess anformbar sind. Die Dome 10 wölben sich in Richtung der Brenneroberteile 4 aus dem Basisabschnitt 5 heraus. Die Dome 10 verhindern, dass überlaufenden Flüssigkeit, wie beispielsweise Wasser, zu den Brennerunterteilen gelangen kann.The flat base section 5 with the stiffening sections 6 and the edge sections 7, 8 is preferably manufactured in a bending, rolling and / or rolling process. So-called domes 10 are provided all around the gas burner 2 and can also be formed, for example, in a rolling process. The domes 10 bulge out of the base section 5 in the direction of the upper burner parts 4. The domes 10 prevent overflowing liquid, such as water, from reaching the lower parts of the burner.

Der Versteifungsabschnitt 6 bzw. die Versteifungsabschnitte 6 sind so angeordnet, dass die Deckplatte 3 in zumindest der ersten Raumrichtung x versteift ist. Hierunter ist zu verstehen, dass die Raumrichtung x als Biegeachse dient, wobei der Versteifungsabschnitt 6 ein Verbiegen oder Verformen der Deckplatte 3 um die Raumrichtung x verhindert. Insbesondere ist der Versteifungsabschnitt 6 so angeordnet, dass die Deckplatte 3 entlang des Versteifungsabschnitts 6 versteift und damit entlang des Versteifungsabschnitts 6 nicht biegbar ist.The stiffening section 6 or the stiffening sections 6 are arranged such that the cover plate 3 is stiffened in at least the first spatial direction x. This is to be understood to mean that the spatial direction x serves as a bending axis, the stiffening section 6 preventing the cover plate 3 from bending or deforming about the spatial direction x. In particular, the stiffening section 6 is arranged such that the cover plate 3 stiffens along the stiffening section 6 and is therefore not bendable along the stiffening section 6.

Die Deckplatte 3 weist weiterhin ein von dem Basisabschnitt 5 getrenntes Versteifungselement 11 auf. Das Versteifungselement 11 und der Basisabschnitt 5 sind vorzugsweise zwei getrennte Bauteile. Vorzugsweise weist die Deckplatte 3 zwei Versteifungselemente 11 auf. Die Versteifungselemente 11 sind an Schnittkanten 12, 13 des Basisabschnitts 5 vorgesehen. Die Versteifungselemente 11 sind vorzugsweise senkrecht zu den Versteifungsabschnitten 6 angeordnet.The cover plate 3 also has a stiffening element 11 which is separate from the base section 5. The stiffening element 11 and the base section 5 are preferably two separate components. The cover plate 3 preferably has two stiffening elements 11. The stiffening elements 11 are provided on cut edges 12, 13 of the base section 5. The stiffening elements 11 are preferably arranged perpendicular to the stiffening sections 6.

Die Versteifungselemente 11 sind dazu eingerichtet, die Deckplatte 3 so zu versteifen, dass diese in der sich von der ersten Raumrichtung x unterscheidenden zweiten Raumrichtung y nicht biegbar ist. Hierunter ist zu verstehen, dass die Raumrichtung y als Biegeachse dient, wobei das Versteifungselement 11 ein Verbiegen oder Verformen der Deckplatte 3 um die Raumrichtung y verhindert. Insbesondere sind die Versteifungselemente 11 dazu eingerichtet, dass die Deckplatte 3 senkrecht zu den Versteifungselementen 11 versteift und nicht biegbar ist. Die Versteifungselemente 11 und die Versteifungsabschnitte 6 sind so positioniert, dass die Deckplatte 3 in den zwei unterschiedlichen Raumrichtungen x, y versteift ist. Wie die Fig. 1 zeigt, sind die Versteifungselemente 11 so ausgebildet, dass sie bündig mit dem Basisabschnitt 5 positioniert sind. Die Versteifungsabschnitte 6 versteifen die Deckplatte 3 in der ersten Raumrichtung x. Die Versteifungselemente 11 versteifen die Deckplatte 3 in der zweiten Raumrichtung y.The stiffening elements 11 are designed to stiffen the cover plate 3 such that it cannot be bent in the second spatial direction y, which differs from the first spatial direction x. This is to be understood to mean that the spatial direction y serves as a bending axis, the stiffening element 11 preventing the cover plate 3 from bending or deforming about the spatial direction y. In particular, the stiffening elements 11 are set up so that the cover plate 3 is stiffened perpendicular to the stiffening elements 11 and is not bendable. The stiffening elements 11 and the stiffening sections 6 are positioned such that the cover plate 3 is stiffened in the two different spatial directions x, y. As the Fig. 1 shows, the stiffening elements 11 are designed such that they are positioned flush with the base section 5. The stiffening sections 6 stiffen the cover plate 3 in the first spatial direction x. The stiffening elements 11 stiffen the cover plate 3 in the second spatial direction y.

Insbesondere sind die Versteifungselemente 11 an zwei senkrecht zu den Randabschnitten 7, 8 angeordneten Schnittkanten 12, 13 des Basisabschnitts 5 angebracht. Das Versteifungselement 11 kann beispielsweise aus einem Kunststoffmaterial oder einem Metallwerkstoff gefertigt sein. Insbesondere kann das Versteifungselement 11 mit dem Basisabschnitt 5 verklebt, verschweißt, vernietet, verschraubt und/oder verclipst sein. Ein Kochfeld 14 kann die Kochstelle 1 aufweisen.In particular, the stiffening elements 11 are attached to two cut edges 12, 13 of the base section 5 arranged perpendicular to the edge sections 7, 8. The stiffening element 11 can for example be made of a plastic material or a metal material. In particular, the stiffening element 11 can be glued, welded, riveted, screwed and / or clipped to the base section 5. A hob 14 can have the hotplate 1.

Die Fig. 2 zeigt in einer schematischen perspektivischen Ansicht eine weitere Ausführungsform einer Kochstelle 1. Die Ausführungsform der Deckplatte 3 der Kochstelle 1 gemäß der Fig. 2 unterscheidet sich von der Ausführungsform der Deckplatte 3 gemäß der Fig. 1 lediglich dadurch, dass die Versteifungselemente 11 leistenförmig sind und bündig mit den Randabschnitten 7, 8 ausgebildet sind. Hierdurch wird um den Basisabschnitt 5 herum mit Hilfe der Versteifungsabschnitte 6 und der Versteifungselemente 11 ein umlaufender Rand gebildet.The Fig. 2 shows a schematic perspective view of another embodiment of a hotplate 1. The embodiment of the cover plate 3 of the hotplate 1 according to the Fig. 2 differs from the embodiment of the cover plate 3 according to the Fig. 1 only in that the stiffening elements 11 are strip-shaped and are formed flush with the edge sections 7, 8. As a result, a circumferential edge is formed around the base section 5 with the aid of the stiffening sections 6 and the stiffening elements 11.

Die Fig. 3 zeigt in einer schematischen perspektivischen Ansicht eine weitere Ausführungsform einer Kochstelle 1. Die Kochstelle 1 ist keine Gaskochstelle sondern eine elektrische Kochstelle. Bei der Ausführungsform der Kochstelle 1 gemäß der Fig. 3 sind daher anstelle der Gasbrenner 2 Massekochplatten 15 vorgesehen.The Fig. 3 shows a schematic perspective view of a further embodiment of a hotplate 1. The hotplate 1 is not a gas hotplate but an electric hotplate. In the embodiment of the hotplate 1 according to the Fig. 3 2 hotplates 15 are therefore provided instead of the gas burner.

Die Ausführungsform der Deckplatte 3 der Kochstelle 1 gemäß der Fig. 3 unterscheidet sich von den Ausführungsformen der Deckplatte 3 gemäß den Fig. 1 und 2 dadurch, dass anstelle von nur zwei Versteifungsabschnitten 6 mehrere Versteifungsabschnitte 6 vorgesehen sind. Insbesondere können, wie in der Fig. 3 gezeigt, sechs Versteifungsabschnitte 6 vorgesehen sein. Die Massekochplatten 15 sind auf erhöhten Zwischenabschnitten 16, 17 des Basisabschnitts 5 positioniert. Die Zwischenabschnitte 16, 17 sind parallel zu der Ebene E bzw. zu dem Basisabschnitt 5 angeordnet.The embodiment of the cover plate 3 of the hotplate 1 according to the Fig. 3 differs from the embodiments of the cover plate 3 according to the Fig. 1 and 2nd in that, instead of only two stiffening sections 6, a plurality of stiffening sections 6 are provided. In particular, as in the Fig. 3 shown, six stiffening sections 6 may be provided. The mass hot plates 15 are positioned on raised intermediate sections 16, 17 of the base section 5. The intermediate sections 16, 17 are arranged parallel to the plane E or to the base section 5.

Die Fig. 4 zeigt in einer schematischen perspektivischen Ansicht eine weitere Ausführungsform einer Kochstelle 1. Die Ausführungsform der Deckplatte 3 der Kochstelle 1 gemäß der Fig. 4 unterscheidet sich von den Ausführungsformen der Deckplatte 3 gemäß den Fig. 1 bis 3 dadurch, dass neben den Versteifungsabschnitten 6 weitere Versteifungsabschnitte 18 vorgesehen sind, die die Deckplatte 3 zusätzlich zu den Versteifungselementen 11 in der zweiten Raumrichtung y versteifen. Die Versteifungsabschnitte 6 sind vorzugsweise senkrecht zu den Versteifungsabschnitten 18 angeordnet. Die Versteifungsabschnitte 6, 18 können einen die Deckplatte 3 umlaufenden Rahmen bilden.The Fig. 4 shows a schematic perspective view of another embodiment of a hotplate 1. The embodiment of the cover plate 3 of the hotplate 1 according to the Fig. 4 differs from the embodiments of the cover plate 3 according to the 1 to 3 in that, in addition to the stiffening sections 6, further stiffening sections 18 are provided, which stiffen the cover plate 3 in addition to the stiffening elements 11 in the second spatial direction y. The stiffening sections 6 are preferably arranged perpendicular to the stiffening sections 18. The stiffening sections 6, 18 can form a frame surrounding the cover plate 3.

Die Seitenwände 21, die Vorderwand 22 und die Rückwand können jeweils aus einem Stahlblech gefertigt sein. Die in der Fig. 5 gezeigte Deckplatte 3 unterscheidet sich von den Ausführungsformen der Deckplatte 3 gemäß den Fig. 1 bis 4 jeweils lediglich dadurch, dass die Versteifungselemente 11 nicht als eigene Bauteile ausgeführt sind, sondern Bestandteil des Korpus 20, insbesondere der Seitenwände 21, sind. Vorzugsweise sind die Versteifungselemente 11 materialeinstückig mit den Seitenwänden 21 ausgebildet. Zur Abstützung und/oder Versteifung der Deckplatte 3 können auch andere Elemente des Standherds 19 dienen. Der Standherd 19 kann die Kochstelle 1 umfassen.The standing hearth 19 has a cuboid housing or a body 20.
