Definitions
- the present invention relates to an oven.
- ovens are designed to provide a variety of different functions.
- the oven must be heat-resistant in order to withstand the temperatures that occur during baking or cooking. Steam escaping from the food being cooked during baking or cooking must not damage the oven.
- Customers also want automatic self-cleaning, such as Ecolyse or Pyrolyse. If residues remain in the oven despite the automatic self-cleaning function, a non-stick coating is beneficial, which enables easy manual cleaning of the oven.
- the oven or the oven should work energy-efficiently.
- the EP 2 128 528 A2 describes an oven muffle with a receiving space that is delimited by wall elements. At least one of the wall elements is transparent to infrared radiation or has an area that is transparent to infrared radiation. A reflection element reflecting infrared radiation is arranged in the area of the outer surface of the wall element facing away from the receiving space.
- the EP 2 196 735 A2 describes a muffle for a cooking appliance, which comprises a frame-like muffle front in which a loading opening is formed. Furthermore, the muffle comprises two side walls which are connected to the front of the muffle, at least one side wall having at least one connecting element which is an element for producing a detachable connection between the side wall and a cover of the muffle.
- the WO 2013/152411 A1 describes an oven with walls, at least one of the walls being made of a high-strength mild steel grade that is coated.
- the DE 198 13 787 A1 describes an oven with a metal oven muffle that can be closed at the front by a door, the muffle walls of which are assigned heating elements for heating the cooking chamber to over approximately 180° C. or the food to be cooked arranged therein.
- the oven includes a protective layer covering the muffle walls at least on the inside. In order to improve the usage properties of the oven muffle, the thickness of the protective layer is less than about 30 ⁇ m.
- the EP 0 995 951 A2 describes a baking oven with means for pyrolytic self-cleaning, with a cooking chamber that can be closed by a door and is delimited by a baking oven muffle, with a first heating element arranged below the top wall of the muffle in the cooking chamber and a second heating element assigned to the bottom wall, the heat output of which during pyrolysis operation is significantly greater than that of the first heating element, the bottom wall being designed as a separate part and being held in the bottom area of the oven muffle above the second heating element and covering it.
- One object of the present invention is to provide an approach that allows the diverse requirements and operating modes of an oven to be met in the best possible way.
- an oven with at least one first and one second flat wall part is proposed.
- the first flat wall part has a first material defining a surface function of the first flat wall part.
- the second flat wall part has a second material defining a surface function of the second flat wall part.
- the first and second material have a different surface function, with the first and second material each being a coating applied to a carrier material, with the coatings pointing towards an interior of the oven, with the coatings being produced using different methods, with one of the flat wall parts being a bottom of the oven, with surface heating in the form of a coating being provided under the bottom, with a carrier material of the bottom being in the form of enamel steel which is provided with a coating in the form of Ecolyse material, with one of the flat wall parts being a side part of the oven , wherein the side part is composed of a carrier material and a coating, the carrier material of the side part being aluminum, the coating of the side part having the functions of radiation reflection, radiation emission, vapor resistance and chemical resistance, and the first flat wall part and the second Wall flat part is separate parts, which are positively, non-positively or materially connected to form the oven.
- One idea on which the present invention is based is to provide an oven with at least two flat wall parts which fulfill different surface functions. This allows different functions to be easily integrated into the oven.
- the first and second flat wall parts are separate parts which are connected to one another in a positive, non-positive or material manner to form the oven.
- a "flat wall part” is to be understood here as a flat part, i.e. a part in which the width and length are a multiple, for example at least ten or at least a hundred times, of the thickness, which at least partially forms a wall of the oven .
- a surface function means an effect on a state or process on the surface of the corresponding flat wall part.
- the first or second flat wall part can also have a third material which defines a further (surface) function of the corresponding flat wall part.
- this can be a heater.
- the function of a material can be selected from the group consisting of: ecolysis, pyrolysis, radiation reflection, radiation emission, non-stick, heating, steam resistance, and/or chemical resistance.
- Ecolyse means the function of decomposing dirt in a temperature range between 260 and 350° on a surface adapted for this.
- the surface has pores in which atmospheric oxygen can be stored and thus made available for the thermal decomposition of the dirt.
- Suitable finishes and Ecolyse materials are in the DE 101 50 825 A1 described.
- temperature-stable materials are glass ceramics, ceramics or enamel.

- Radio Radiation emission means the function of the first and second materials to absorb incident electromagnetic radiation.
- the degree of emissivity also known as the emissivity coefficient, indicates how much radiation the material emits compared to an ideal heat radiator, i.e. a black body. Insofar as the function of radiation emission is mentioned here, this means that at least more than 90% of thermal radiation with a wavelength of between 1 and 10 ⁇ m is emitted at a material temperature between 350 and 600°.
- non-stick is meant a quality of the first and second materials such that soiling is prevented from being baked into them. Such non-stick materials are correspondingly easy to clean.
- the "heating" function means that the first or second material forms surface heating.
- the surface heating can be an APS surface heating or a PEMS surface heating.
- APS surface heating means, in particular, surface heating in which the dielectric and the heating conductor are applied to the substrate by means of atmospheric plasma spraying.
- PEMS panel heaters are in particular flat heaters in which the dielectric consists of enamel, onto which the heating conductor tracks are printed in the form of a layout using a screen printing process.
- vapour resistance it is meant that the material in question cannot be damaged by vapor.
- “Chemical resistance” means, in particular, resistance to chemicals commonly used in the household and to food and food degradation products.
- the first and second material have a different chemical composition.
- first and second materials differ in their relative or structural formula.
- the chemical composition of a material can be selected from the group consisting of: enamelled steel, chrome steel, stainless steel, stainless steel, hot-dip aluminized sheet, aluminum, ceramic, glass-ceramic, enamel, PTFE, sol-gel material and/or ecolyse material.

- PTFE polytetrafluoroethylene
- PTFE polytetrafluoroethylene
- a ceramic non-stick layer can provide the non-stick and chemical resistance function as well as sol-gel material intended as the non-stick material.
- Tarnish protection made of sol-gel material can, for example, provide the function of pyrolysis and reflection of radiation.
- An anti-tarnish layer prevents stainless steel from discolouring, which occurs as a result of oxidation of the stainless steel surface from approx. 200°C.
- a tarnish protection produced using the CVD process can provide the functions of pyrolysis and radiation reflection.
- An Ecolyse material such as in the DE 101 50 825 A1 described, can provide the ecolysis function.
- the Ecolyse material can have a structure of porous particles and a binder, with the porous particles having no solid or liquid second phase in their pores.
- the porous particles can be metal oxides, carbides or nitrides.
- the first and second material each form a coating, with the coatings being produced using different methods.
- the different methods are selected from the group consisting of: Electrostatic coating, dipping, squeegeeing, spraying, gas phase deposition and/or printing.
- the enamel can be applied to an enamelling steel in a powder enamelling process, in particular an electrostatic powder enamelling process, wet coating process or dipping process.
- the first flat wall part has a carrier material and at least one coating, the coating being formed from the first material.
- the second flat wall part has a carrier material and at least one coating, the coating being formed from the second material.
- a flat wall part can be selected from the group consisting of: flange, cover, base, first side wall, second side wall and/or rear wall.
- a first, second, third, fourth, fifth or sixth material can be assigned to the flange, the top, the bottom, the first side wall, the second side wall and the rear wall, these materials each providing different surface functions.
- the first and second side walls will generally be provided with the same surface function.
- first and second flat wall parts are connected to one another by means of assembly, screwing, riveting, forming, welding, soldering and/or gluing.
- the first and second flat wall part should therefore first be provided with the first or second material and only then be connected to one another to form the oven.
- the oven is a household appliance.
- the first flat wall part is provided with a coating of the first material and the second flat wall part is provided with a coating of the second material before the first and second flat wall parts are connected to one another to form the oven.

Zuallererst muss das Backrohr hitzebeständig sein, um den im Back- oder Garbetrieb auftretenden Temperaturen standzuhalten. Auch im Back- oder Garbetrieb aus dem Gargut austretender Wasserdampf darf das Backrohr nicht beschädigen. Ferner wünschen sich Kunden eine Selbstreinigungsautomatik, wie Ecolyse oder Pyrolyse. Sollten trotz Selbstreinigungsautomatik Rückstände im Backrohr verbleiben, so ist eine Antihaftbeschichtung günstig, die eine einfache manuelle Reinigung des Backrohrs ermöglicht. Nicht zuletzt soll der Backofen bzw. das Backrohr energieeffizient arbeiten.Nowadays, ovens are designed to provide a variety of different functions. First and foremost, the oven must be heat-resistant in order to withstand the temperatures that occur during baking or cooking. Steam escaping from the food being cooked during baking or cooking must not damage the oven. Customers also want automatic self-cleaning, such as Ecolyse or Pyrolyse. If residues remain in the oven despite the automatic self-cleaning function, a non-stick coating is beneficial, which enables easy manual cleaning of the oven. Last but not least, the oven or the oven should work energy-efficiently.

Erfindungsgemäß wird ein Backrohr mit zumindest einem ersten und einem zweiten Wandungsflachteil vorgeschlagen. Das erste Wandungsflachteil weist ein eine Oberflächenfunktion des ersten Wandungsflachteils definierendes, erstes Material auf. Das zweite Wandungsflachteil weist ein eine Oberflächenfunktion des zweiten Wandungsflachteils definierendes, zweites Material auf. Das erste und zweite Material weisen eine unterschiedliche Oberflächenfunktion auf, wobei das erste und zweite Material jeweils eine auf ein Trägermaterial aufgebrachte Beschichtung ist, wobei die Beschichtungen zu einem Innenraum des Backrohrs hinweisen, wobei die Beschichtungen in unterschiedlichen Verfahren hergestellt sind, wobei eines der Wandungsflachteile ein Boden des Backrohrs ist, wobei unter dem Boden eine Flächenheizung in Form einer Beschichtung vorgesehen ist, wobei ein Trägermaterial des Bodens als Emaillierstahl ausgebildet ist, das mit einer Beschichtung in Form von Ecolyse-Material versehen ist, wobei eines der Wandungsflachteile ein Seitenteil des Backrohrs ist, wobei sich das Seitenteil aus einem Trägermaterial und einer Beschichtung zusammensetzt, wobei das Trägermaterial des Seitenteils Aluminium ist, wobei die Beschichtung des Seitenteils die Funktionen der Strahlungsreflektion, Strahlungsemission, Dampfbeständigkeit sowie chemische Beständigkeit hat, und wobei es sich bei dem ersten Wandungsflachteil und dem zweiten Wandungsflachteil um separate Teile handelt, welche zum Bilden des Backrohrs form-, kraft- oder stoffschlüssig miteinander verbunden sind.According to the invention, an oven with at least one first and one second flat wall part is proposed. The first flat wall part has a first material defining a surface function of the first flat wall part. The second flat wall part has a second material defining a surface function of the second flat wall part. The first and second material have a different surface function, with the first and second material each being a coating applied to a carrier material, with the coatings pointing towards an interior of the oven, with the coatings being produced using different methods, with one of the flat wall parts being a bottom of the oven, with surface heating in the form of a coating being provided under the bottom, with a carrier material of the bottom being in the form of enamel steel which is provided with a coating in the form of Ecolyse material, with one of the flat wall parts being a side part of the oven , wherein the side part is composed of a carrier material and a coating, the carrier material of the side part being aluminum, the coating of the side part having the functions of radiation reflection, radiation emission, vapor resistance and chemical resistance, and the first flat wall part and the second Wall flat part is separate parts, which are positively, non-positively or materially connected to form the oven.
Eine der vorliegenden Erfindung zugrunde liegende Idee besteht darin, ein Backrohr mit zumindest zwei Wandungsflachteilen vorzusehen, welche unterschiedliche Oberflächenfunktionen erfüllen. Dadurch können auf einfache Weise unterschiedliche Funktionen in das Backrohr integriert werden.One idea on which the present invention is based is to provide an oven with at least two flat wall parts which fulfill different surface functions. This allows different functions to be easily integrated into the oven.
Erfindungsgemäß handelt es sich bei dem ersten und zweiten Wandungsflachteil um separate Teile, welche zum Bilden des Backrohrs miteinander form-, kraft- oder stoffschlüssig verbunden sind.According to the invention, the first and second flat wall parts are separate parts which are connected to one another in a positive, non-positive or material manner to form the oven.
Unter einem "Wandungsflachteil" ist vorliegend ein flächiges Teil, also ein solches Teil, bei welchem die Breite und Länge jeweils ein Vielfaches, beispielsweise zumindest ein Zehn- oder zumindest Hundertfaches, der Dicke beträgt, zu verstehen, welches eine Wandung des Backrohrs zumindest teilweise ausbildet.A "flat wall part" is to be understood here as a flat part, i.e. a part in which the width and length are a multiple, for example at least ten or at least a hundred times, of the thickness, which at least partially forms a wall of the oven .
Mit einer Oberflächenfunktion ist ein Einwirken auf einen Zustand oder Prozess an der Oberfläche des entsprechenden Wandungsflachteils gemeint.A surface function means an effect on a state or process on the surface of the corresponding flat wall part.
Das erste oder zweite Wandungsflachteil kann auch ein drittes Material aufweisen, das eine weitere (Oberflächen-) Funktion des entsprechenden Wandungsflachteils definiert. Beispielsweise kann dieses eine Heizung sein.The first or second flat wall part can also have a third material which defines a further (surface) function of the corresponding flat wall part. For example, this can be a heater.
Die Funktion eines Materials kann ausgewählt werden aus der Gruppe bestehend aus: Ecolyse, Pyrolyse, Strahlungsreflektion, Strahlungsemission, Antihaft, Heizung, Dampfbeständigkeit und/oder chemische Beständigkeit.The function of a material can be selected from the group consisting of: ecolysis, pyrolysis, radiation reflection, radiation emission, non-stick, heating, steam resistance, and/or chemical resistance.
Mit "Ecolyse" ist die Funktion des Zersetzens von Verschmutzungen in einem Temperaturbereich zwischen 260 und 350° auf einer dafür angepassten Oberfläche gemeint. Die Oberfläche weist Poren auf, in welchen der Luftsauerstoff gespeichert und damit für den thermischen Abbau der Verschmutzungen bereitgestellt werden kann. Geeignete Oberflächen und Ecolyse-Materialien sind in der
Bei der Pyrolyse wird das Backrohr auf zumindest 400° aufgeheizt. Bei dieser Temperatur zersetzen sich vorhandene Verschmutzungen. Entsprechend temperaturstabile Materialien sind Glaskeramiken, Keramiken oder Emaille. Auch ein Sol-Gel-Material oder eine CVD-Beschichtung (also eine solche Beschichtung, welche mittels Gasphasenabscheidung hergestellt ist) kann die für die Pyrolyse erforderliche Temperaturbeständigkeit sowie die dafür günstige Oberflächenbeschaffenheit bereitstellen. Im CVD-Verfahren können beispielsweise folgende Materialien abgeschieden werden: SiO2, SiOx, TiO2, Al2O3, DLC, Polysiloxane, amorphe Kohlenwasserstoffe, fluorierte Kohlenwasserstoffe.During pyrolysis, the oven is heated to at least 400°. At this temperature, existing dirt decomposes. Correspondingly temperature-stable materials are glass ceramics, ceramics or enamel. A sol-gel material or a CVD coating (i.e. a coating of this type which is produced by means of gas phase deposition) can also have the temperature resistance required for the pyrolysis and the temperature resistance required for it provide favorable surface finish. The following materials, for example, can be deposited in the CVD process: SiO2, SiOx, TiO2, Al2O3, DLC, polysiloxanes, amorphous hydrocarbons, fluorinated hydrocarbons.
Unter "Strahlungsreflektion" ist der Anteil der Wärmestrahlung zu verstehen, welcher von dem ersten oder zweiten Material reflektiert wird. Eine Strahlungsreflektionsfunktion meint vorliegend eine Strahlungsreflektion von zumindest 30 %. Mit "Strahlungsemission" ist vorliegend die Funktion des ersten und zweiten Materials gemeint, auftreffende elektromagnetische Strahlung zu absorbieren. Der Emissionsgrad, auch als Emissionskoeffizient bezeichnet, gibt an, wie viel Strahlung das Material im Vergleich zu einem idealen Wärmestrahler, also einem schwarzen Körper, abgibt. Soweit vorliegend von der Funktion einer Strahlungsemission gesprochen wird, so ist hiermit gemeint, dass Wärmestrahlung mit einer Wellenlänge von zwischen 1 und 10 µm bei einer Materialtemperatur zwischen 350 und 600° zumindest größer 90% emittiert wird."Reflection of radiation" means the portion of the thermal radiation that is reflected by the first or second material. In the present case, a radiation reflection function means a radiation reflection of at least 30%. As used herein, "radiation emission" means the function of the first and second materials to absorb incident electromagnetic radiation. The degree of emissivity, also known as the emissivity coefficient, indicates how much radiation the material emits compared to an ideal heat radiator, i.e. a black body. Insofar as the function of radiation emission is mentioned here, this means that at least more than 90% of thermal radiation with a wavelength of between 1 and 10 μm is emitted at a material temperature between 350 and 600°.
Mit "Antihaft" ist eine Beschaffenheit des ersten und des zweiten Materials gemeint, so dass ein Einbrennen von Verschmutzungen in dieses verhindert wird. Entsprechend einfach lassen sich solche Antihaft-Materialien reinigen.By "non-stick" is meant a quality of the first and second materials such that soiling is prevented from being baked into them. Such non-stick materials are correspondingly easy to clean.
Mit der Funktion "Heizung" ist gemeint, dass das erste oder zweite Material eine Flächenheizung ausbildet. Bei der Flächenheizung kann es sich um eine APS-Flächenheizung oder eine PEMS-Flächenheizung handeln. Unter APS-Flächenheizung versteht man insbesondere flächige Heizungen, bei denen auf Substraten das Dielektrikum und der Heizleiter mittels atmosphärischem Plasmaspritzen aufgetragen werden. PEMS-Flächenheizungen sind insbesondere flächige Heizungen, bei denen das Dielektrikum aus Emaille besteht, auf das mittels Siebdruckverfahren die Heizleiterbahnen in Form eines Layouts aufgedruckt werden.The "heating" function means that the first or second material forms surface heating. The surface heating can be an APS surface heating or a PEMS surface heating. APS surface heating means, in particular, surface heating in which the dielectric and the heating conductor are applied to the substrate by means of atmospheric plasma spraying. PEMS panel heaters are in particular flat heaters in which the dielectric consists of enamel, onto which the heating conductor tracks are printed in the form of a layout using a screen printing process.
Mit "Dampfbeständigung" ist gemeint, dass das entsprechende Material durch Dampf nicht beschädigt werden kann.By "vapour resistance" it is meant that the material in question cannot be damaged by vapor.
Mit "chemischer Beständigkeit" ist insbesondere eine Beständigkeit gegen im Haushalt übliche Chemikalien sowie Lebensmittel und Lebensmittelabbauprodukte gemeint."Chemical resistance" means, in particular, resistance to chemicals commonly used in the household and to food and food degradation products.
Gemäß einer Ausführungsform weisen das erste und zweite Material eine unterschiedliche chemische Zusammensetzung auf.According to one embodiment, the first and second material have a different chemical composition.
Damit ist gemeint, dass sich das erste und zweite Material in ihrer Verhältnis- oder Strukturformel unterscheiden.By this is meant that the first and second materials differ in their relative or structural formula.
Die chemische Zusammensetzung eines Materials kann ausgewählt werden aus der Gruppe bestehend aus: Emaillierstahl, Chromstahl, rostfreier Stahl, Edelstahl, feueraluminiertes Feinblech, Aluminium, Keramik, Glaskeramik, Emaille, PTFE, Sol-Gel-Material und/oder Ecolyse-Material. Beispielsweise kann Edelstahl die Funktionen Strahlungsreflektion, Strahlungsemission, Dampfbeständigkeit und chemische Beständigkeit bereitstellen. Entsprechendes gilt auch für eloxiertes Aluminium, insbesondere feueraluminiertes Feinblech.The chemical composition of a material can be selected from the group consisting of: enamelled steel, chrome steel, stainless steel, stainless steel, hot-dip aluminized sheet, aluminum, ceramic, glass-ceramic, enamel, PTFE, sol-gel material and/or ecolyse material. For example, stainless steel can provide the functions of radiation reflection, radiation emission, vapor resistance, and chemical resistance. The same also applies to anodised aluminium, in particular hot-dip aluminised sheet metal.
Glaskeramik kann beispielsweise die Funktion Pyrolyse, Dampfbeständigkeit und chemische Beständigkeit bereitstellen.For example, glass-ceramics can provide the function of pyrolysis, steam resistance, and chemical resistance.
Keramik kann insbesondere die Funktion Pyrolyse, Strahlungsemission, Dampfbeständigkeit und chemische Beständigkeit bereitstellen.In particular, ceramics can provide the function of pyrolysis, radiation emission, steam resistance, and chemical resistance.
Farbiges Emaille auf Emaillierstahl kann beispielsweise die Funktion Pyrolyse, Strahlungsemission, Dampfbeständigkeit und chemische Beständigkeit bereitstellen.For example, colored enamel on enamelling steel can provide the function of pyrolysis, radiation emission, steam resistance and chemical resistance.
Transparentes Emaille auf Edelstahl kann beispielsweise die Funktion Pyrolyse, Strahlungsreflektion, Dampfbeständigkeit und chemische Beständigkeit bereitstellen.For example, transparent enamel on stainless steel can provide the function of pyrolysis, radiation reflection, steam resistance, and chemical resistance.
PTFE (Polytetrafluorethylen) kann beispielsweise die Funktionen Antihaft und chemische Beständigkeit bereitstellen.For example, PTFE (polytetrafluoroethylene) can provide the functions of non-stick and chemical resistance.
Eine keramische Antihaftschicht kann beispielsweise die Funktion Antihaft und chemische Beständigkeit bereitstellen genauso wie Sol-Gel-Material, das als Antihaft-Material vorgesehen ist.For example, a ceramic non-stick layer can provide the non-stick and chemical resistance function as well as sol-gel material intended as the non-stick material.
Ein Anlaufschutz aus Sol-Gel-Material kann beispielsweise die Funktion Pyrolyse und Strahlungsreflektion bereitstellen. Eine Anlaufschutzschicht verhindert das Verfärben von Edelstahl, das durch Oxidation der Edelstahloberfläche ab ca. 200°C auftritt.Tarnish protection made of sol-gel material can, for example, provide the function of pyrolysis and reflection of radiation. An anti-tarnish layer prevents stainless steel from discolouring, which occurs as a result of oxidation of the stainless steel surface from approx. 200°C.
Beispielsweise kann ein im CVD-Verfahren (Gasphasenbeschichtungsverfahren) hergestellter Anlaufschutz die Funktionen Pyrolyse und Strahlungsreflektion bereitstellen.For example, a tarnish protection produced using the CVD process (vapor phase coating process) can provide the functions of pyrolysis and radiation reflection.
Ein Ecolyse-Material, wie beispielsweise in der
Das erste und zweite Material bilden jeweils eine Beschichtung aus, wobei die Beschichtungen in unterschiedlichen Verfahren hergestellt sind.The first and second material each form a coating, with the coatings being produced using different methods.
Dies stellt eine weitere Möglichkeit dar, um zwei Wandungsflachteile mit unterschiedlichen Oberflächenfunktionen auf einfache Weise herzustellen.This represents a further possibility for producing two flat wall parts with different surface functions in a simple manner.
Gemäß einer weiteren Ausführungsform sind die unterschiedlichen Verfahren ausgewählt aus der Gruppe bestehend aus: Elektrostatisches Beschichten, Tauchen, Rakeln, Aufsprühen, Gasphasenabscheiden und/oder Bedrucken.According to a further embodiment, the different methods are selected from the group consisting of: Electrostatic coating, dipping, squeegeeing, spraying, gas phase deposition and/or printing.
Beispielsweise kann das Emaille in einem Pulveremaillierungsverfahren, insbesondere einem elektrostatischen Pulveremaillierungsverfahren, Nassbeschichtungsverfahren oder Tauchverfahren auf einen Emaillierstahl aufgebracht werden.For example, the enamel can be applied to an enamelling steel in a powder enamelling process, in particular an electrostatic powder enamelling process, wet coating process or dipping process.
Erfindungsgemäß weist das erste Wandungsflachteil ein Trägermaterial und zumindest eine Beschichtung auf, wobei die Beschichtung aus dem ersten Material gebildet sind.According to the invention, the first flat wall part has a carrier material and at least one coating, the coating being formed from the first material.
Erfindungsgemäß weist das zweite Wandungsflachteil ein Trägermaterial und zumindest eine Beschichtung auf, wobei die Beschichtung aus dem zweiten Material gebildet ist.According to the invention, the second flat wall part has a carrier material and at least one coating, the coating being formed from the second material.
Ein Wandungsflachteil kann ausgewählt werden aus der Gruppe bestehend aus: Flansch, Deckel, Boden, erste Seitenwand, zweite Seitenwand und/oder Rückwand. Beispielsweise kann dem Flansch, der Decke, dem Boden, der ersten Seitenwand, der zweiten Seitenwand und der Rückwand ein erstes, zweites, drittes, viertes, fünftes bzw. sechstes Material zugeordnet sein, wobei diese Materialien jeweils unterschiedliche Oberflächenfunktionen bereitstellen. Vorzugsweise wird man in der Regel die erste und zweite Seitenwand jedoch mit derselben Oberflächenfunktion vorsehen.A flat wall part can be selected from the group consisting of: flange, cover, base, first side wall, second side wall and/or rear wall. For example, a first, second, third, fourth, fifth or sixth material can be assigned to the flange, the top, the bottom, the first side wall, the second side wall and the rear wall, these materials each providing different surface functions. Preferably, however, the first and second side walls will generally be provided with the same surface function.
Gemäß einer weiteren Ausführungsform sind das erste und zweite Wandungsflachteil mittels Zusammensetzens, Schraubens, Nietens, Umformens, Schweißens, Lötens und/oder Klebens miteinander verbunden.According to a further embodiment, the first and second flat wall parts are connected to one another by means of assembly, screwing, riveting, forming, welding, soldering and/or gluing.
Das erste und zweite Wandungsflachteil sollen also jeweils zunächst mit dem ersten bzw. zweiten Material vorgesehen werden und hiernach erst zum Bilden des Backrohrs miteinander verbunden werden.The first and second flat wall part should therefore first be provided with the first or second material and only then be connected to one another to form the oven.
Weiterhin wird ein Backofen mit dem vorstehend beschriebenen Backrohr bereitgestellt.Furthermore, an oven with the oven described above is provided.
Des Weiteren wird ein Verfahren gemäß dem Anspruch 6 bereitgestellt.Furthermore, a method according to
Bei dem Backofen handelt es sich um ein Haushaltsgerät.The oven is a household appliance.
Gemäß einer Ausführungsform werden das erste Wandungsflachteil mit einer Beschichtung aus dem ersten Material und das zweite Wandungsflachteil mit einer Beschichtung aus dem zweiten Material vorgesehen, bevor das erste und zweite Wandungsflachteil miteinander zum Bilden des Backrohrs miteinander verbunden werden.According to one embodiment, the first flat wall part is provided with a coating of the first material and the second flat wall part is provided with a coating of the second material before the first and second flat wall parts are connected to one another to form the oven.

Die Beschichtung 3b hat die Funktionen der Strahlungsreflektion, Strahlungsemission, Dampfbeständigkeit sowie chemische Beständigkeit. Die so hergestellten Seitenwände 3 sind beispielsweise gegenüber Stahlteilen vorteilhaft, da sie aufgrund ihrer Strahlungsreflektion und Strahlungsemission energiesparend wirken.
