Description

Die Erfindung bezieht sich auf ein Gargerät gemäß dem Oberbegriff des Patentanspruches 1.The invention relates to a cooking appliance according to the preamble of claim 1.

Aus der EP-A-0222216 ist ein Gargerät bekannt mit einem durch eine Tür verschließbaren Garraum einer Gargerätemuffel, in whelchem Garraum ein oberes Strahlungsfenster für einen Oberhitzestrahlungsheizkörper sowie ein unteres Strahlungsfenster für einen Unterhitzestrahlungsheizkörper angeordnet ist.From the EP-A-0222216 a cooking device is known with a closable by a door cooking chamber a cooking appliance muffle, in which cooking chamber an upper radiation window for a top heat radiation heater and a lower radiation window is arranged for a bottom heat radiator.

Aus der DE 35 39 880 A1 ist ein Backofen mit einem durch eine Tür verschließbaren Garraum einer Backofenmuffel bekannt. In der Backofenmuffel sind ein Oberhitzestrahlungsheizkörper mit einem oberen strahlungsdurchlässigen Strahlungsfenster und ein Unterhitzestrahlungsheizkörper mit einem unteren strahlungsdurchlässigen Strahlungsfenster vorgesehen. Die Strahlungsfenster schützen die Strahlungsheizkörper vor Verunreinigungen. Darüber hinaus kann das untere Strahlungsfenster als Abstellfläche für Gargutbehälter oder unmittelbar für Gargut dienen.From the DE 35 39 880 A1 an oven is known with a closable by a door cooking chamber of a baking oven muffle. In the oven muffle a Oberhitzestrahlungsheizkörper with an upper radiation-permeable radiation window and a Unterhitzestrahlungsheizkörper with a lower radiation-permeable radiation window are provided. The radiation windows protect the radiant heaters from contamination. In addition, the lower radiation window can serve as a storage area for food containers or directly for food.

Der Garraum des oben erwähnt Backofens wird also durch die strahlungsdurchlässigen Strahlungsfenster aufgrund der Wärmestrahlung der Strahlungsheizkörper aufgeheizt, so daß beispielsweise bei kaltem Backofen die gewünschte Arbeitstemperatur äußerst schnell erreicht werden kann. Die Strahlungsfenster sind lichtdurchlässig oder durchsichtig und ermöglichen es, daß ohne einen gesonderten, innerhalb der Backofenmuffel anzuordnenden Grillheizkörper - also mit denselben Strahlungsheizkörpern, die auch für die normale Beheizung des Backofens vorgesehen sind - gegrillt werden kann. Die Strahlungsfenster sind durch eine Platte aus Glaskeramik oder dergleichen gebildet und vorzugsweise an Flanschprofilen der sie umgebenden Wandungsteile der zugehörigen Muffelwandung befestigt.The cooking chamber of the above-mentioned oven is thus heated by the radiation-permeable radiation window due to the heat radiation of the radiant heater, so that for example when the oven is cold, the desired operating temperature can be reached very quickly. The radiation windows are translucent or transparent and allow it to be grilled without a separate grill radiator to be arranged inside the oven muffle - ie with the same radiant heaters which are also provided for the normal heating of the oven. The radiation windows are formed by a plate made of glass ceramic or the like and are preferably fastened to flange profiles of the surrounding wall parts of the associated muffle wall.

Die Aufgabe der Erfindung besteht darin, ein Gargerät zu schaffen, in dem Gargut mit einfachen Mitteln effektiver und schneller gegart werden kann.The object of the invention is to provide a cooking appliance, can be cooked in the food with simple means more effective and faster.

Erfindungsgemäß wird die Aufgabe der Erfindung durch ein Gargerät gemäß dem Patentanspruch 1 gelöst. In dem erfindungsgemäßen Gargerät ist in Kombination ein unteres Strahlungsfenster beispielsweise aus Glaskeramik und ein oberes Strahlungsfenster angeordnet. Das obere Strahlungsfenster weist einen Transmissionsgrad auf, dessen Wert zumindest in einem für das Garen relevanten Wellenlängenbereich der Wärmestrahlung von etwa 0 bis 10 µm, insbesondere in einem Wellenlängenbereich von 0,5 bis 5 µm, im wesentlichen konstant ist. Dadurch wird sichergestellt, daß ein konstanter, ausreichend großer Anteil der Wärmestrahlen, deren Wellenlängen in dem relevanten Wellenlängenbereich liegen, von dem oberen Strahlungsfenster durchgelassen wird. Dies ist insbesondere deshalb wichtig, weil durch das Glaskeramikmaterial des unteren Strahlungsfensters Wärmestrahlen bestimmter Wellenlängen in dem relevanten Wellenlängenbereich nahezu vollständig zurückgehalten werden. Diese Wärmestrahlen können allerdings erfindungsgemäß zumindest durch das obere Strahlungsfenster zu einem ausreichend großen Anteil in den Garraum eintreten. Der konstante Wert des Transmissionsgrades des oberen Strahlungsfensters wird durch eine Gitterstruktur erzielt. Dabei hängt die Größe des Transmissionsgrades insbesondere von der durchschnittlichen Maschenweite der Gitterstruktur ab, d.h. bei größerer Maschenweite erhöht sich der Wert des Transmissionsgrades der Gitterstruktur. Die Gitterstruktur ist bevorzugt durch ein Gewebe aus Keramikfasern gebildet, das im Garbetrieb vom Oberhitzestrahlungsheizkörper stark erwärmt wird. Durch die starke Erwärmung werden Fettspritzer oder dergleichen auf dem Gewebe verbrannt, wodurch ein gewisser Selbstreinigungseffekt auf dem Gewebe erzielt wird. Die Maschenweite des Gewebes ist dabei derart gewählt, daß sich ein gewünschter Wert des Transmissionsgrades des oberen Strahlungsfensters einstellt. Als zusätzliche Schutzmaßnahme für einen Benutzer kann das Gewebe aus Keramikfasern mit einem geerdeten Metallgitter abgedeckt werden.According to the invention the object of the invention is achieved by a cooking appliance according to the patent claim 1. In the cooking appliance according to the invention a lower radiation window, for example of glass ceramic and an upper radiation window is arranged in combination. The upper radiation window has a transmittance whose value is at least in one for cooking relevant wavelength range of the heat radiation of about 0 to 10 microns, in particular in a wavelength range of 0.5 to 5 microns, is substantially constant. This ensures that a constant, sufficiently large proportion of the heat rays, whose wavelengths are in the relevant wavelength range, is transmitted by the upper radiation window. This is particularly important because heat rays of specific wavelengths in the relevant wavelength range are almost completely retained by the glass ceramic material of the lower radiation window. However, according to the invention, these heat rays can enter the cooking chamber at least through the upper radiation window to a sufficiently large extent. The constant value of the transmittance of the upper radiation window is achieved by a lattice structure. In this case, the size of the transmittance depends in particular on the average mesh size of the lattice structure, ie with a larger mesh size, the value of the transmittance of the lattice structure increases. The lattice structure is preferably formed by a fabric made of ceramic fibers, which is strongly heated by the top heat radiation heater in the cooking mode. The excessive heating causes fat splashes or the like to be burnt on the fabric, thereby achieving a certain self-cleaning effect on the fabric. The mesh size of the fabric is chosen such that sets a desired value of the transmittance of the upper radiation window. As an additional protective measure for a user, the fabric of ceramic fibers may be covered with a grounded metal grid.

Vorteilhafterweise sind die Strahlungsheizkörper Bandheizleiter. Diese weisen im Vergleich zu Rohrheizkörpern eine geringe Ansprechzeit von etwa zwei bis drei Sekunden auf, so daß im Garraum die gewünschte Arbeitstemperatur äußerst schnell erreicht wird.Advantageously, the radiant heaters Bandheizleiter. These have in comparison to tubular heaters a low response time of about two to three seconds, so that the desired working temperature is reached extremely quickly in the oven.

Alternativ können die Strahlungsheizkörper durch Quarzstrahlungsheizkörper gebildet sein. Quarzstrahlungsheizkörper können mit einer Abschirmung versehen werden, mit der die Wärmestrahlung von der Abschirmung weg reflektiert wird. Dies ist insbesondere von Vorteil, wenn eine richtungsunabhängige Wärmestrahlung vermieden werden soll. Da somit eine effiziente Nutzung von begrenztem Garraum möglich ist, werden derartige Quarzstrahlungsheizkörper insbesondere bei kompakteren Gargeräten angewendet, deren Garraum gering ist.Alternatively, the radiant heaters may be formed by quartz radiant heaters. Quartz radiant heaters can be provided with a shield, with which the heat radiation is reflected away from the shield. This is particularly advantageous if a direction-independent heat radiation is to be avoided. Thus, since an efficient use of limited cooking space is possible, such Quartz radiators used in particular for more compact cooking appliances whose cooking space is low.

Um das Gargut gleichmäßig zu erwärmen, verlaufen die Bandheizleiter als Flächenheizkörper über die gesamte, dem Garraum zugewandte Fläche der Ober- und/oder Unterhitzestrahlungsheizkörperanordnung. Dadurch wird eine gleichmäßige Verteilung der Heizleistung über die Fläche der Ober- und/oder Unterhitzestrahlungsheizkörperanordnung ermöglicht.In order to heat the food evenly, the Bandheizleiter run as surface heating over the entire, the cooking chamber facing surface of the upper and / or Unterhitzestrahlungsheizkörperanordnung. As a result, a uniform distribution of the heating power over the surface of the top and / or bottom heat radiating heater arrangement is made possible.

Um die Fertigungskosten beträchtlich zu verringern und um eine vereinfachte Montage zu erreichen, sind die Ober- und/oder Unterhitzestrahlungsheizkörperanordnung zumindest in wesentlichen Teilen baugleich ausgebildet.In order to reduce the manufacturing costs considerably and to achieve a simplified installation, the top and / or bottom heat radiation heater assembly are at least substantially identical in construction.

Vorteilhaft ist der Oberhitzestrahlungsheizkörper innerhalb der Gargerätemuffel angeordnet. Dadurch werden einerseits Isolationsprobleme im Bereich der Deckwand der Gargerätemuffel minimiert. Andererseits fällt die Notwendigkeit weg, Einbauöffnungen zum Einsetzen der Heizkörperanordnung des Oberhitzestrahlungsheizkörper in einer Muffelwand der Gargerätemuffel vorzusehen.Advantageously, the top heat radiator is arranged inside the cooking appliance muffle. This minimizes isolation problems in the area of the top wall of the cooking appliance muffle. On the other hand, eliminates the need to provide installation openings for inserting the radiator assembly of the top heat radiation heater in a muffle wall of the Gargerätemuffel.

Gemäß einem bevorzugten Ausführungsbeispiel sind das untere Strahlungsfenster und der Unterhitzestrahlungsheizkörper in einem Garraumteiler angeordnet, der in den Garraum einsetzbar ist zum Aufteilen des Garraums. Dadurch kann in einem Garraumbereich zwischen der Oberhitze des Gargeräts und dem Garraumteiler in einer kurzen Ansprechzeit ein hoher Strahlungsanteil zum Garen genutzt werden. Zugleich ist die Glas- oder Glaskeramik-Abdeckplatte des Garraumteilers äußerst leicht zu reinigen, sofern dieser aus dem Garraum herausgenommen ist.According to a preferred embodiment, the lower radiation window and the lower heat radiating heater are arranged in a cooking space divider, which can be inserted into the cooking chamber for dividing the cooking chamber. As a result, a high proportion of radiation can be used for cooking in a cooking chamber area between the top heat of the cooking appliance and the cooking space divider in a short response time. At the same time the glass or glass ceramic cover plate of the cooking compartment divider is extremely easy to clean, provided that it is removed from the oven.

Die Glas- oder Glaskeramik-Abdeckplatte des erfindungsgemäßen Garraumteilers ist wesentlich geringeren Belastungen ausgesetzt als beispielsweise eine Glas- oder Glaskeramik-Abdeckplatte für ein Kochfeld. Daher kann die Abdeckplatte des Garraumteilers mit einer vergleichsweisen geringen Materialstärke ausgebildet werden. Durch die geringere Materialstärke wird das Gesamtgewicht des Garraumteilers verringert, während zugleich die Strahlungsdurchlässigkeit der Abdeckplatte erhöht wird. Beispielsweise ist für die Glas- oder Glaskeramik-Abdeckplatte des erfindungsgemäßen Garraumteilers eine Materialstärke von 3 mm ausreichend, wogegen die Materialstärke einer Glaskeramik-Abdeckplatte für ein Kochfeld bei etwa 4 mm liegt.The glass or glass ceramic cover plate of the cooking space divider according to the invention is exposed to much lower loads than, for example, a glass or glass ceramic cover plate for a hob. Therefore, the cover plate of the cooking chamber divider can be formed with a comparatively small material thickness. Due to the lower material thickness, the total weight of the cooking space divider is reduced, while at the same time the radiation permeability of the cover plate is increased. For example, for the glass or glass ceramic cover plate of the invention Garraumteilers sufficient material thickness of 3 mm, whereas the material thickness of a glass ceramic cover plate for a hob is about 4 mm.

Um das Gargut gleichmäßig zu erwärmen, verläuft ein als Bandheizleiter ausgebildeter Unterhitzestrahlungsheizkörper des Garraumteilers in Form eines Flächenheizkörpers über die gesamte Fläche des Garraumteilers. Dadurch wird eine gleichmäßige Verteilung der Heizleistung über die Fläche des Garraumteilers ermöglicht. Durch die gleichmäßige Verteilung der Heizleistung werden selbst bei einem sehr geringen Abstand zwischen Oberhitze und Garraumteiler gute Garergebnisse erzielt.In order to heat the food evenly, runs as Bandheizleiter formed Unterhitzestrahlungsheizkörper the cooking space divider in the form of a surface heating element over the entire surface of the cooking space divider. This allows a uniform distribution of the heating power over the surface of the cooking space divider. Due to the even distribution of the heating power good cooking results are achieved even with a very small distance between the top heat and cooking space divider.

The upper radiator assembly 7 has a trough-like radiator housing 9, in which a Insulator 11 is added. On the insulating body 11 is a Bandheizleiter 8 bedded as Oberhitzestrahlungsheizkörper. The Bandheizleiter 8 extends not only annular in the peripheral region of the upper radiator assembly 7, but as surface radiator over the entire surface of the upper radiator assembly 7. The peripheral edge of the trough-like radiator housing 9 framed an upper radiation window 13 of the upper radiator assembly 7, through which the Bandheizleiter 8 heat radiation in the Cooking chamber 3 radiates. The upper radiation window 13 is formed by a fabric 15 made of ceramic fibers. As a protective measure for a user, the fabric 15 is covered by a coarse-meshed grounded metal grid 17.

Gegenüber der oberen Heizkörperanordnung 7 ist in einer Bodenöffnung 29 des Muffelbodens der Gargerätemuffel 1 eine untere Heizkörperanordnung 19 eingesetzt, die eine Unterhitze vorsieht. Die untere Heizkörperanordnung 19 weist ein Heizkörpergehäuse 23, einen darin aufgenommenen Isolierkörper 25 sowie einen im Isolierkörper 25 eingebetteten Bandheizleiter 21 auf. Diese Bauteile der unteren Heizkörperanordnung 19 sind baugleich ausgebildet wie die entsprechenden Bauteile der oberen Heizkörperanordnung 7.Opposite the upper radiator assembly 7, a lower radiator assembly 19 is provided in a bottom opening 29 of the muffle bottom of the cooking appliance muffle 1, which provides a bottom heat. The lower heating element arrangement 19 has a radiator housing 23, an insulating body 25 accommodated therein and a band heating conductor 21 embedded in the insulating body 25. These components of the lower radiator assembly 19 are of identical design as the corresponding components of the upper radiator assembly. 7

Im Gegensatz zum oberen Strahlungsfenster 13 ist ein unteres Strahlungsfenster 27 durch eine Glaskeramikplatte 28 gebildet. Gemäß der Figur 1 schließt die Glaskeramikplatte 28 der unteren Heizkörperanordnung 19 bündig mit dem Muffelboden ab. Dabei kann die dem Garraum 3 zugewandte Seite der Glaskeramikplatte 28 als Abstellfläche für einen Gargutbehälter 31 dienen. Darüber hinaus können in bekannter Weise Gargutträger auch in nicht dargestellte Einschubführungen an Seitenwänden der Gargerätemuffel eingeschoben werden.In contrast to the upper radiation window 13, a lower radiation window 27 is formed by a glass ceramic plate 28. According to FIG. 1, the glass-ceramic plate 28 of the lower heating element arrangement 19 is flush with the muffle bottom. Here, the cooking chamber 3 facing side of the glass ceramic plate 28 serve as a storage area for a food container 31. In addition, in a known manner Gargutträger be inserted into not shown insertion guides on side walls of the cooking appliance muffle.

Während eines Betriebs des Gargeräts strahlt sowohl der Oberhitze- als auch Unterhitzestrahlungsheizkörper 8 und 21 Wärmestrahlung durch die oberen und unteren Strahlungsfenster 13 und 28 in den Garraum 3. Hierbei bestimmt der Transmissionsgrad des oberen und des unteren Strahlungsfensters 13 und 28, welche Anteile der Wärmestrahlung von den oberen und unteren Strahlungsfenstern 13 und 28 durchgelassen werden.During operation of the cooking appliance, both the top heat and bottom heat radiant heaters 8 and 21 radiate heat radiation through the top and bottom radiation windows 13 and 28 into the cooking chamber 3. Here, the transmittance of the top and bottom radiation windows 13 and 28 determines which portions of the heat radiation from the upper and lower radiation windows 13 and 28 are transmitted.

Diese Anteile der Wärmestrahlung sind in dem Diagramm aus der Figur 3 abschnittsweise in einem Wellenlängenbereich von 0 bis etwa 3,5 µm gezeigt. Demnach ist in dem Wellenlängenbereich ein Transmissionsgrad des oberen Strahlungsfensters 13 mit einem konstanten Wert τ1 von beispielsweise 0,8 gewählt worden. Dieser Wert des Transmissionsgrad ist erfindungsgemäß zumindest in einem Wellenlängenbereich von 0 bis 10 µm im wesentlichen konstant. Dadurch wird sichergestellt, daß ein konstanter Anteil der Wärmestrahlen, deren Wellenlängen zwischen etwa 0 und 10 µm liegen, zumindest zu einem Anteil von 80% von dem oberen Strahlungsfenster 13 durchgelassen wird.These portions of the thermal radiation are shown in the diagram of Figure 3 sections in a wavelength range of 0 to about 3.5 microns. Accordingly, in the wavelength range, a transmittance of the upper radiation window 13 having a constant value τ 1 of, for example, 0.8 has been selected. This value of the transmittance is according to the invention substantially constant at least in a wavelength range of 0 to 10 microns. This ensures that a constant portion of the heat rays whose wavelengths are between about 0 and 10 microns, at least a portion of 80% from the upper radiation window 13 is transmitted.

Im Gegensatz zu dem konstanten Wert τ1 des Transmissionsgrades des oberen Strahlungsfensters 13 unterliegt der Wert τ2 des Transmissionsgrades des unteren Glaskeramik-Strahlungsfensters 27 in Abhängigkeit von der Wellenlänge starken Schwankungen. So beträgt beispielsweise gemäß dem Diagramm aus der Figur 3 der Wert τ2 des Transmissionsgrades des unteren Strahlungsfensters 27 bei einer Wellenlänge λ von 2,9 µm nur etwa 0,05. Folglich werden Wärmestrahlen einer Wellenlänge λ von 2,9 µm vom unteren Strahlungsfenster 27 größtenteils nicht durchgelassen.In contrast to the constant value τ 1 of the transmittance of the upper radiation window 13, the value τ 2 of the transmittance of the lower glass-ceramic radiation window 27 varies widely depending on the wavelength. For example, according to the diagram of FIG. 3, the value τ 2 of the transmittance of the lower radiation window 27 at a wavelength λ of 2.9 μm is only about 0.05. As a result, heat rays having a wavelength λ of 2.9 μm from the lower radiation window 27 are largely not transmitted.

Gerade die Wärmestrahlen einer Wellenlänge von 2,9 µm sind sehr energiereiche und daher für ein effektives Garen wichtige Wärmestrahlen, wie anhand des Diagramms aus der Figur 4 verdeutlicht ist. Gemäß der Figur 4 liegen nämlich die von den Bandheizleitern 8 und 21 bei einer Temperatur von 1100K emittierten Wärmestrahlen einer Wellenlänge λ von 2,9 µm in der Nähe eines Maximums der Energieverteilungskurve. Hierbei ist anzumerken, daß sich die in der Figur 4 gezeigte spektrale Energieverteilung ΔP/Δλ auf einen schwarzen Körper bezieht, der näherungsweise den Heizbandleitern 8, 21 gleichgestellt ist.Just the heat rays of a wavelength of 2.9 microns are very high energy and therefore important for effective cooking heat rays, as illustrated by the diagram of Figure 4. Namely, as shown in FIG. 4, the heat rays emitted by the band heaters 8 and 21 at a temperature of 1100K of a wavelength λ of 2.9 μm are close to a maximum of the energy distribution curve. It should be noted that the spectral energy distribution .DELTA.P / .DELTA.λ shown in FIG. 4 relates to a black body, which is approximately equal to the heating band conductors 8, 21.

In der Figur 2 ist ein zweites Ausführungsbeispiel des erfindungsgemäßen Gargeräts gezeigt. Das Gargerät ist mit seiner Rückseite nach Art eines Hängeschranks an einer vertikalen Küchenwand 39 montiert. Der Garraum 3 innerhalb der Gargerätemuffel 1 kann über ein frontseitig im Gargerät angeordnetes Sichtfenster 41 kontrolliert werden. Die Gargerätemuffel 1 weist eine bodenseitige Muffelöffnung 33 auf, die mit der bodenseitigen Tür 5 verschließbar ist. In der Figur 2 ist die bodenseitige Tür 2 abgesenkt gezeigt, wobei sie mit ihrer Unterseite in Anlage mit einer Arbeitsplatte 37 einer Kücheneinrichtung ist.FIG. 2 shows a second embodiment of the cooking appliance according to the invention. The cooking appliance is mounted with its back in the manner of a hanging cabinet on a vertical kitchen wall 39. The cooking chamber 3 within the cooking appliance muffle 1 can be controlled via a front mounted in the cooking appliance viewing window 41. The cooking appliance muffle 1 has a bottom-side muffle opening 33 which is connected to the bottom side Door 5 is lockable. In the figure 2, the bottom-side door 2 is shown lowered, being with its underside in contact with a worktop 37 of a kitchen device.

Die bodenseitige Tür 5 ist mit Hubelementen 35 des Gargeräts verbunden. Die Hubelemente 35 können mittels einer in der Figur 2 gestrichelt angedeuteten Antriebsvorrichtung 43 des Gargeräts verstellt werden. Um den Garraum 3 zu verschließen, wird die bodenseitige Tür 5 mittels der Hubelemente 35 in Anlage mit einem die Garraumöffnung 33 umgebenden Muffelrahmen 45 gebracht.The bottom-side door 5 is connected to lifting elements 35 of the cooking appliance. The lifting elements 35 can be adjusted by means of a dashed line in FIG. 2, indicated drive device 43 of the cooking appliance. In order to close the cooking chamber 3, the bottom-side door 5 is brought by means of the lifting elements 35 into abutment with a muffle frame 45 surrounding the cooking chamber opening 33.

Die bodenseitige Tür 5 weist einen Türrahmen 47 auf, der auf seiner dem Garraum 3 zugewandten Seite offen ist. Diese offene Seite ist durch eine Glaskeramikplatte 28 abgedeckt. Unterhalb der Glaskeramikplatte 28 ist die untere Heizkörperanordung 19 angeordnet. Dabei ist der Umfangsrand des wannenartigen Heizkörpergehäuses 23 der unteren Heizkörperanordung 19 mit einer Unterseite der Glaskeramikplatte 28 verbunden.The bottom-side door 5 has a door frame 47 which is open on its side facing the cooking chamber 3. This open side is covered by a glass ceramic plate 28. Below the glass ceramic plate 28, the lower Heizkörperanordung 19 is arranged. In this case, the peripheral edge of the trough-like radiator housing 23 of the lower Heizkörperanordung 19 is connected to an underside of the glass ceramic plate 28.

Der unteren Heizkörperanordnung 19 gegenüberliegend ist an der Deckwand 2 der Gargerätemuffel 1 eine obere Heizkörperanordnung 7 geordnet, deren Bauteile denen des ersten Ausführungsbeispiels entsprechen.The lower radiator assembly 19 opposite is arranged on the top wall 2 of the cooking appliance muffle 1, an upper radiator assembly 7, whose components correspond to those of the first embodiment.

Wie aus dem dritten Ausführungsbeispiel der Figur 4 hervorgeht, ist der Garraum 3 der Gargerätemuffel 1 durch einen plattenartigen Garraumteiler 30 unterteilt, der auf nicht gezeigten Führungen an den Seitenwänden der Gargerätemuffel 1 lagert. Der Garraumteiler 30 weist gemäß der Figur 5 ein wannenartiges Gehäuse 38 auf. In dem Gehäuse 38 ist ein Isolierkörper 36 aufgenommen, auf dem ein Bandheizleiter 34 gebettet ist. Der Bandheizleiter 34 verläuft nicht nur ringförmig im Umfangsbereich des Garraumteilers 30, sondern erstreckt sich als ein Flächenheizkörper über die gesamte Fläche des Garraumteilers 30.As is apparent from the third embodiment of Figure 4, the cooking chamber 3 of the cooking appliance muffle 1 is divided by a plate-like cooking space divider 30, which is mounted on guides, not shown, on the side walls of the cooking appliance muffle 1. The cooking space divider 30 has a trough-like housing 38 according to FIG. In the housing 38, an insulating body 36 is accommodated, on which a Bandheizleiter 34 is embedded. The Bandheizleiter 34 not only extends annularly in the peripheral region of the cooking space divider 30, but extends as a surface heater over the entire surface of the cooking space divider 30th

Der Umfangsrand des wannenartigen Gehäuses 38 ist mit einer Glas- oder Glaskeramik-Abdeckplatte 32 des Garraumteilers 30 in Verbindung. Die Glas- oder Glaskeramik-Abdeckplatte 32 dient als Abstellfläche für einen Gargutbehälter 31. Darüber hinaus ragt aus einer Stirnseite des Gehäuses 38 ein elektrischer Steckkontakt 40 für den Bandheizleiter 34 des Garraumteilers 30. Bei in den Garraum 3 eingesetztem Garraumteiler 30 ist der elektrische Steckkontakt 40 zur Stromversorgung mit einem nicht gezeigten Steckanschluß an einer Rückwand der Gargerätemuffel in Verbindung.The peripheral edge of the trough-like housing 38 is connected to a glass or glass ceramic cover plate 32 of the cooking space divider 30 in combination. The glass or glass ceramic cover plate 32 serves as a storage area for a food container 31. In addition, protrudes from an end face of the housing 38, an electrical plug contact 40 for the Bandheizleiter 34 of the cooking compartment divider 30. When inserted into the cooking chamber 3 Cooking chamber divider 30 is the electrical plug-in contact 40 for power supply with a plug-in connection, not shown on a rear wall of the cooking appliance muffle in combination.

Im Betrieb des Gargeräts mit darin eingesetztem Garraumteiler 30 ist die untere Heizkörperanordnung 19 durch eine nicht gezeigte Steuereinrichtung des Gargeräts deaktiviert. Anstelle dessen wird der eingesetzte Garraumteiler 30 mit elektrischem Strom versorgt, so daß der Garraumbereich zwischen der Oberhitzestrahlungsheizkörperanordnung 7 und dem Garraumteiler 30 beheizt wird. Hierbei bestimmt der Wert des Transmissionsgrades des oberen Strahlungsfensters 13 und der Glaskeramik-Abdeckplatte 32 des Garraumteilers 30, welche Anteile der Wärmestrahlung von dem oberen Strahlungsfenster 13 bzw. der Glaskeramik-Abdeckplatte 32 des Garraumteilers 28 durchgelassen werden.During operation of the cooking appliance with the cooking space divider 30 inserted therein, the lower heating element arrangement 19 is deactivated by a control device, not shown, of the cooking appliance. Instead, the inserted cooking chamber divider 30 is supplied with electric current, so that the cooking chamber area between the top heat radiation heater assembly 7 and the cooking space divider 30 is heated. In this case, the value of the transmittance of the upper radiation window 13 and the glass ceramic cover plate 32 of the cooking space divider 30 determines which portions of the heat radiation are transmitted by the upper radiation window 13 or the glass ceramic cover plate 32 of the cooking space divider 28.
