A "bottom surface element" of the outer housing unit is to be understood in particular as an element which in particular has an at least essentially flat shape and which forms a bottom of the outer housing unit in particular in an installed position. In particular, the base surface element is arranged in an installed position in an area of the outer housing unit facing away from the hob plate and/or forms this area at least to a large extent. The floor surface element has in particular a main plane of extent which, in at least one assembled state, is aligned at least essentially parallel to a main plane of extent of the hob plate. In particular, the floor area element has a longitudinal extension and a transverse extension, which in particular jointly span a plane aligned parallel to the main extension plane of the floor area element. The floor area element has in particular a thickness which is at most 20%, in particular at most 10%, advantageously at most 5%, particularly advantageously at most 3% and preferably at most 1% of a value of the longitudinal extent of the floor area element. A "main extension plane" of an object is to be understood in particular as a plane which is parallel to a largest side face of the smallest imaginary geometric cuboid which just completely encloses the object and in particular runs through the center point of the cuboid. A "longitudinal extent" of an object is to be understood in particular as an extent of a longest side of the smallest imaginary geometric cuboid which just about completely encloses the object.

Durch die erfindungsgemäße Ausgestaltung kann insbesondere eine langlebige Ausgestaltung erreicht werden. Insbesondere kann eine hohe Steifigkeit, insbesondere gegenüber bei einem Transport auftretender eine äußere Kraft verursachender Kräfte, bei gleichzeitig hoher Flexibilität, insbesondere um im Falle einer Verformung in eine Ausgangsposition zurückzukehren, ermöglicht werden. Vorteilhaft können Objekte, wie beispielsweise zumindest ein Heizelement und/oder eine Steuereinheit und/oder eine Gebläseeinheit, ihren vorbestimmten Platz einnehmen, wodurch insbesondere eine hohe Funktionstüchtigkeit und/oder ein hoher Komfort für einen Bediener erreicht werden können/kann. Kosten, welche bei einer Herstellung der Außengehäuseeinheit und/oder der Kochfeldeinheit auftreten, können vorteilhaft wenigstens im Wesentlichen konstant gehalten werden.

Objects such as at least one heating element and/or a control unit and/or a blower unit can advantageously take up their predetermined place, as a result of which a high level of functionality and/or a high level of comfort for an operator are achieved in particular can. Costs that occur during production of the outer housing unit and/or the hob unit can advantageously be kept at least essentially constant. In particular, additional production costs, for example due to higher material consumption and/or a longer production time, can be avoided.

Die Verstärkungseinheit und das Bodenflächenelement könnten insbesondere separat voneinander ausgebildet sein. Beispielsweise könnten die Verstärkungseinheit und das Bodenflächenelement getrennt voneinander ausgebildete und/oder angeordnete Bestandteile der Außengehäuseeinheit sein. Die Verstärkungseinheit und das Bodenflächenelement sind vorzugsweise wenigstens teilweise einstückig ausgebildet. Insbesondere ist die Verstärkungseinheit einstückig mit einem Teilbereich des Bodenflächenelements ausgebildet. Vorzugsweise ist die Verstärkungseinheit als eine Ausformung des Bodenflächenelements ausgebildet. Unter einer "Ausformung" eines Objekts soll eine Stanzung und/oder Einprägung und/oder Einkerbung und/oder Bombierung des Objekts verstanden werden. Insbesondere ist die Verstärkungseinheit als eine Bombierung des Bodenflächenelements ausgebildet. Dadurch kann insbesondere eine preiswerte Herstellung der Verstärkungseinheit und/oder eine platzsparende Ausgestaltung erzielt werden.The reinforcement unit and the floor area element could in particular be formed separately from one another. For example, the reinforcement unit and the base surface element could be components of the outer housing unit that are constructed and/or arranged separately from one another. The reinforcement unit and the floor panel are preferably formed at least partially in one piece. In particular, the reinforcement unit is formed in one piece with a partial area of the floor surface element. The reinforcement unit is preferably designed as a formation of the floor surface element. A “shaping” of an object is to be understood as meaning a punching and/or embossing and/or notching and/or cambering of the object. In particular, the reinforcement unit is designed as a crowning of the floor area element. In this way, in particular, an inexpensive production of the reinforcement unit and/or a space-saving design can be achieved.

Die Kochfeldvorrichtung umfasst zumindest ein Federelement, das dazu vorgesehen ist, zumindest ein Heizelement wenigstens teilweise gegen eine Kochfeldplatte zu drücken, wobei die Verstärkungseinheit dazu vorgesehen ist, eine durch eine Federkraft des Federelements hervorgerufene Verformung zumindest eines Teilbereichs des Bodenflächenelements wenigstens wesentlich zu reduzieren. Das Federelement ist insbesondere dazu vorgesehen, wenigstens das Heizelement und vorteilhaft zumindest ein weiteres Objekt, insbesondere zumindest ein Raumteilerelement und/oder zumindest ein Abschirmelement, ausgehend von dem Teilbereich des Bodenflächenelements in einer von dem Bodenflächenelement abgewandten Richtung, welche insbesondere der Kochfeldplatte zugewandt ausgerichtet ist, zu drücken. Das Federelement ist insbesondere dazu vorgesehen, eine Federkraft von mindestens 40 N, insbesondere von mindestens 60 N, vorteilhaft von mindestens 75 N, besonders vorteilhaft von mindestens 100 N und vorzugsweise von mindestens 120 N zu erzeugen. Insbesondere ist die Federkraft als äußere Kraft ausgebildet, welche in wenigstens einem montierten Zustand auf das Bodenflächenelement einwirkt. In wenigstens einem montierten Zustand ist das Federelement insbesondere wenigstens zu einem Großteil zwischen dem Bodenflächenelement und dem Heizelement angeordnet. Das Federelement ist in wenigstens einem montierten Zustand insbesondere wenigstens im Wesentlichen senkrecht zu der Haupterstreckungsebene des Bodenflächenelements und/oder zu einer Haupterstreckungsebene des Heizelements ausgerichtet. Die von dem Federelement erzeugte Federkraft wirkt in wenigstens einem montierten Zustand insbesondere wenigstens im Wesentlichen senkrecht zu der Haupterstreckungsebene des Bodenflächenelements auf das Bodenflächenelement ein. Unter der Wendung, dass eine Gerade und/oder Ebene "wenigstens im Wesentlichen senkrecht" zu einer weiteren, von der einen Gerade und/oder Ebene getrennt ausgebildeten Gerade und/oder Ebene ausgerichtet ist, soll insbesondere verstanden werden, dass die Gerade und/oder Ebene mit der weiteren Gerade und/oder Ebene bei einer Projektion auf zumindest eine Projektionsebene, in der zumindest eine der Geraden und/oder einer der Ebenen angeordnet ist, einen Winkel einschließt, der um maximal 15°, insbesondere um maximal 10°, vorteilhaft um maximal 7°, besonders vorteilhaft um maximal 5° und vorzugsweise um maximal 3° von einem Winkel von 90° abweicht. Unter der Wendung, dass das Federelement dazu vorgesehen ist, zumindest ein Heizelement "wenigstens teilweise" gegen eine Kochfeldplatte zu drücken, soll insbesondere verstanden werden, dass das Federelement dazu vorgesehen ist, das Heizelement alleine und/oder gemeinsam mit zumindest einem weiteren Federelement gegen die Kochfeldplatte zu drücken. Unter einer "Verformung" eines Teilbereichs des Bodenflächenelements soll insbesondere eine Auslenkung des Teilbereichs, welche insbesondere zumindest aus der auf den Teilbereich einwirkenden Federkraft des Federelements resultiert, aus einem Zustand verstanden werden, welchen der Teilbereich insbesondere in wenigstens einem kraftlosen Zustand annimmt. Unter der Wendung, dass die Verstärkungseinheit dazu vorgesehen ist, eine durch eine Federkraft des Federelements hervorgerufene Verformung zumindest eines Teilbereichs des Bodenflächenelements "wenigstens wesentlich zu reduzieren", soll insbesondere verstanden werden, dass die Verstärkungseinheit dazu vorgesehen ist, eine durch das Federelement hervorgerufene maximale Auslenkung des Teilbereichs zuzulassen, welche einen Wert von maximal 95 %, insbesondere von maximal 90 %, vorteilhaft von maximal 85 %, besonders vorteilhaft von maximal 80 % und vorzugsweise von maximal 75 % eines Wert einer maximalen Auslenkung eines Teilbereichs eines Bodenflächenelements einer Verstärkungseinheitenlosen Außengehäuseeinheit annimmt. Dadurch können sich Objekte der Kochfeldvorrichtung insbesondere unabhängig von bei einem Transport auftretenden, äußere Kräfte hervorrufenden Kräften in einer Einbaulage bei einem Bediener an ihren vorgesehenen Positionen befinden, wodurch insbesondere eine hohe Leistungsfähigkeit der Objekte garantiert werden kann. Insbesondere kann eine einem Heizelement zu einer Erhitzung eines aufgestellten Gargeschirrs zugeführte Energie auf Grundlage einer Position des Heizelements kalkuliert werden, in welcher das Heizelement angeordnet sein sollte.The hob device comprises at least one spring element, which is intended to press at least one heating element at least partially against a hob plate, with the reinforcement unit being intended to at least significantly reduce a deformation of at least one partial region of the base surface element caused by a spring force of the spring element. The spring element is provided in particular for at least the heating element and advantageously at least one further object, in particular at least one space-dividing element and/or at least one shielding element, starting from the partial area of the base surface element in a direction away from the base surface element, which is aligned in particular towards the hob plate, to press. The spring element is intended in particular to generate a spring force of at least 40 N, in particular at least 60 N, advantageously at least 75 N, particularly advantageously at least 100 N and preferably at least 120 N. In particular, the spring force is designed as an external force which acts on the floor surface element in at least one assembled state. In at least one assembled state, the spring element is arranged, in particular at least to a large extent, between the floor surface element and the heating element. The spring element is in in at least one mounted state, in particular at least substantially perpendicular to the main plane of extension of the floor area element and/or to a main plane of extension of the heating element. In at least one assembled state, the spring force generated by the spring element acts on the floor surface element, in particular at least essentially perpendicularly to the main extension plane of the floor surface element. The expression that a straight line and/or plane is aligned “at least essentially perpendicularly” to another straight line and/or plane that is separate from the one straight line and/or plane is to be understood in particular as meaning that the straight line and/or plane with the additional straight line and/or plane in a projection onto at least one projection plane in which at least one of the straight lines and/or one of the planes is arranged, encloses an angle of at most 15°, in particular at most 10°, advantageously around deviates from an angle of 90° by a maximum of 7°, particularly advantageously by a maximum of 5° and preferably by a maximum of 3°. The phrase that the spring element is intended to press at least one heating element "at least partially" against a hob plate should be understood in particular to mean that the spring element is intended to press the heating element alone and/or together with at least one other spring element against the to press the hob plate. A "deformation" of a partial area of the floor surface element is to be understood in particular as a deflection of the partial area, which results in particular at least from the spring force of the spring element acting on the partial area, from a state which the partial area assumes in particular in at least one powerless state. The phrase that the reinforcement unit is intended to "at least significantly reduce" a deformation caused by a spring force of the spring element in at least one partial area of the floor surface element is to be understood in particular as meaning that the reinforcement unit is intended to reduce a maximum deflection caused by the spring element of the partial area, which assumes a value of a maximum of 95%, in particular a maximum of 90%, advantageously a maximum of 85%, particularly advantageously a maximum of 80% and preferably a maximum of 75% of a value of a maximum deflection of a partial area of a base surface element of an outer housing unit without reinforcement units. As a result, objects of the hob device can be located in their intended positions in an installed position with an operator, particularly independently of external forces that cause external forces during transport, as a result of which a high level of performance of the objects can be guaranteed in particular. In particular, a heating element for heating a placed Energy supplied to cookware can be calculated based on a position of the heating element in which the heating element should be located.

Weiterhin wird vorgeschlagen, dass die Verstärkungseinheit zumindest ein Verstärkungselement aufweist, welches eine wenigstens im Wesentlichen stabförmige Gestalt aufweist. Unter einer "wenigstens im Wesentlichen stabförmigen Gestalt" eines Objekts soll insbesondere verstanden werden, dass das Objekt eine Längserstreckung aufweist, welche wesentlich größer ist als eine größte weitere Erstreckung des Objekts, wie beispielsweise eine Dicke und/oder eine Quererstreckung und/oder ein Durchmesser, und/oder welche einen Wert von mindestens 5-mal, insbesondere von mindestens 10-mal, vorteilhaft von mindestens 15-mal, besonders vorteilhaft von mindestens 20-mal und vorzugsweise von mindestens 25-mal eines Werts der größten weiteren Erstreckung des Objekts annimmt. Dadurch kann insbesondere eine preiswerte und/oder einfache Herstellung des Verstärkungselements erzielt werden.Furthermore, it is proposed that the reinforcement unit has at least one reinforcement element which has an at least essentially rod-like shape. An "at least essentially rod-shaped shape" of an object is to be understood in particular as meaning that the object has a longitudinal extent that is significantly greater than a further greatest extent of the object, such as a thickness and/or a transverse extent and/or a diameter, and/or which assumes a value of at least 5 times, in particular at least 10 times, advantageously at least 15 times, particularly advantageously at least 20 times and preferably at least 25 times a value of the greatest further extension of the object. In this way, in particular, an inexpensive and/or simple production of the reinforcement element can be achieved.

In einer Einbaulage könnte das Verstärkungselement insbesondere direkt unterhalb des Federelements angeordnet sein. Vorzugsweise ist das Verstärkungselement in einem Nahbereich des Federelements angeordnet. Das Verstärkungselement und das Federelement sind in wenigstens einem montierten Zustand insbesondere wenigstens im Wesentlichen überlappend angeordnet. Insbesondere ist ein Randbereich des Verstärkungselements in wenigstens einem montierten Zustand überlappend mit einem Randbereich des Federelements angeordnet. Unter einem "Nahbereich" eines Objekts, insbesondere des Federelements, soll insbesondere ein Bereich verstanden werden, welcher bei einer Betrachtung einer Projektion des Objekts auf eine Ebene von dem Objekt, insbesondere von einem Mittelpunkt und/oder Schwerpunkt des Objekts, einen minimalen Abstand von maximal 10 cm, insbesondere von maximal 5 cm, vorteilhaft von maximal 3 cm, besonders vorteilhaft von maximal 1 cm und vorzugsweise von maximal 0,5 cm aufweist. Dadurch kann insbesondere eine hohe Stabilität in dem Nahbereich erreicht werden. Insbesondere kann eine Verstärkung in einem Bereich vorgesehen werden, von welchem eine Ursache der Verformung ausgeht.In one installation position, the reinforcement element could be arranged in particular directly below the spring element. The reinforcement element is preferably arranged in a region close to the spring element. In at least one assembled state, the reinforcement element and the spring element are arranged in particular at least essentially overlapping. In particular, an edge area of the reinforcement element is arranged overlapping with an edge area of the spring element in at least one assembled state. A "near area" of an object, in particular of the spring element, is to be understood in particular as an area which, when viewing a projection of the object onto a plane from the object, in particular from a center point and/or center of gravity of the object, has a minimum distance of maximum 10 cm, in particular a maximum of 5 cm, advantageously a maximum of 3 cm, particularly advantageously a maximum of 1 cm and preferably a maximum of 0.5 cm. In this way, in particular, a high level of stability can be achieved in the close-up range. In particular, reinforcement can be provided in an area from which a cause of the deformation originates.

Zudem wird vorgeschlagen, dass das Verstärkungselement eine Längserstreckung aufweist, welche wenigstens im Wesentlichen parallel zu einer Seitenkante des Bodenflächenelements ausgerichtet ist. Die Seitenkante könnte in einer Einbaulage insbesondere eine seitliche Begrenzungskante des Bodenflächenelements sein, welche insbesondere in der Einbaulage eine Frontkante und eine Rückkante des Bodenflächenelements wenigstens im Wesentlichen miteinander verbinden könnte. Vorteilhaft ist die Seitenkante in der Einbaulage als eine Frontkante des Bodenflächenelements ausgebildet. Die Frontkante bildet in einer Einbaulage insbesondere eine einem Bediener nächstgelegene Kante des Bodenflächenelements aus. Dadurch kann insbesondere eine einfache und/oder automatisierte Herstellung des Verstärkungselements erzielt werden.In addition, it is proposed that the reinforcing element has a longitudinal extent which is aligned at least essentially parallel to a side edge of the floor surface element. In an installed position, the side edge could in particular be a lateral boundary edge of the floor area element, which could at least essentially connect a front edge and a rear edge of the floor area element to one another in the installed position. The side edge in the installation position is advantageous as a front edge of the Floor surface element formed. In an installation position, the front edge forms in particular an edge of the floor surface element that is closest to an operator. In this way, in particular, simple and/or automated production of the reinforcement element can be achieved.

Weiterhin wird vorgeschlagen, dass die Verstärkungseinheit zumindest ein zweites Verstärkungselement aufweist, welches eine wenigstens im Wesentlichen stabförmige Gestalt aufweist, wodurch insbesondere eine hohe Stabilität ermöglicht werden kann.Furthermore, it is proposed that the reinforcement unit has at least one second reinforcement element, which has an at least essentially rod-like shape, as a result of which a high degree of stability can be made possible in particular.

Das Verstärkungselement und das zweite Verstärkungselement könnten beispielsweise schräg relativ zueinander ausgerichtet sein und insbesondere zumindest einen Punkt gemeinsam haben. Hierbei könnten das Verstärkungselement und das zweite Verstärkungselement beispielsweise in Form eines V und/oder in Form eines X angeordnet sein. Insbesondere sind das Verstärkungselement und das zweite Verstärkungselement wenigstens im Wesentlichen parallel zueinander ausgerichtet. Vorzugsweise ist das zweite Verstärkungselement beabstandet zu dem ersten Verstärkungselement angeordnet. Insbesondere weisen das Verstärkungselement und das zweite Verstärkungselement einen Abstand von mindestens 10 cm, insbesondere von mindestens 15 cm, vorteilhaft von mindestens 20 cm, besonders vorteilhaft von mindestens 25 cm, vorzugsweise von mindestens 30 cm und besonders bevorzugt von mindestens 35 cm auf. Der Abstand zwischen dem Verstärkungselement und dem zweiten Verstärkungselement ist insbesondere senkrecht zu der Längserstreckung des Verstärkungselements und/oder zu der Längserstreckung des zweiten Verstärkungselements ausgerichtet. Vorzugsweise ist das zweite Verstärkungselement in einem Nahbereich zumindest eines weiteren Federelements angeordnet. Dadurch kann insbesondere ein Großteil der Außengehäuseeinheit durch die Verstärkungseinheit stabilisiert werden. Insbesondere kann sowohl das Federelement als auch das weitere Federelement gezielt stabilisiert werden, wodurch eine hohe Stabilität in wesentlichen Bereichen der Außengehäuseeinheit, welche insbesondere einer erhöhten Krafteinwirkung ausgesetzt sind, erreicht werden.The reinforcement element and the second reinforcement element could, for example, be aligned obliquely relative to one another and in particular have at least one point in common. In this case, the reinforcement element and the second reinforcement element could be arranged, for example, in the shape of a V and/or in the shape of an X. In particular, the reinforcement element and the second reinforcement element are aligned at least substantially parallel to one another. The second reinforcement element is preferably arranged at a distance from the first reinforcement element. In particular, the reinforcing element and the second reinforcing element are at a distance of at least 10 cm, in particular at least 15 cm, advantageously at least 20 cm, particularly advantageously at least 25 cm, preferably at least 30 cm and particularly preferably at least 35 cm. The distance between the reinforcement element and the second reinforcement element is in particular aligned perpendicular to the longitudinal extent of the reinforcement element and/or to the longitudinal extent of the second reinforcement element. The second reinforcement element is preferably arranged in the vicinity of at least one further spring element. In this way, in particular, a large part of the outer housing unit can be stabilized by the reinforcement unit. In particular, both the spring element and the further spring element can be stabilized in a targeted manner, as a result of which a high level of stability can be achieved in essential areas of the outer housing unit, which in particular are exposed to increased forces.

Beispielsweise könnte die Verstärkungseinheit zumindest zwei weitere Verstärkungselemente aufweisen, welche insbesondere wenigstens im Wesentlichen konzentrisch und insbesondere wenigstens im Wesentlichen zwischen dem Verstärkungselement und dem zweiten Verstärkungselement angeordnet sein könnten. Vorzugsweise weist die Verstärkungseinheit zumindest ein drittes Verstärkungselement auf, welches dazu vorgesehen ist, das Verstärkungselement und das zweite Verstärkungselement miteinander zu verbinden. Beispielsweise könnte das dritte Verstärkungselement eine Längserstreckung aufweisen, welche wenigstens im Wesentlichen senkrecht zu der Längserstreckung des Verstärkungselements und/oder zu der Längserstreckung des zweiten Verstärkungselements ausgerichtet sein könnte. Insbesondere weist das dritte Verstärkungselement eine Längserstreckung auf, welche schräg relativ zu der Längserstreckung des Verstärkungselements und/oder zu der Längserstreckung des zweiten Verstärkungselements ausgerichtet ist.
