Description

Die Erfindung befaßt sich mit einer Anordnung mit einem Backofen und einem darüber angeordnetem Oberschrank gemäß dem Oberbegriff des Patenanspruches 1.The invention relates to an arrangement with an oven and one above arranged wall unit according to the preamble of patent claim 1.

Aus der Druckschrift DE 30 42 906 A1 ist ein Back- und Bratofen mit einem Garraum und einer an einer Wrasenöffnung im Garraum angeschlossenen Wrasenabzugseinrichtung sowie einem Druckkanal für Kühlluft, welche von einem Kühlgebläse durch das Herdgehäuse gefördert wird, bekannt. Dabei mündet die Wrasenabzugseinrichtung unmittelbar im Druckkanal. Die Wrasenabzugseinrichtung ist an der Rückseite des Garraums senkrecht verlaufend geführt und weist eine mit der Wrasenöffnung des Garraumes korrespondierende Einlaßöffnung auf. Zusätzlich ist der Druckkanal oberhalb des Garraumes waagrecht verlaufend geführt und endet in einer frontseitigen Wrasen- bzw. Luftaustrittsblende.From the document DE 30 42 906 A1 is a baking and roasting oven with a cooking space and a vapor extraction device connected to a vapor opening in the cooking space as well as a pressure channel for cooling air, which from a cooling fan through the Stove housing is promoted, known. The vapor extraction device opens directly in the pressure channel. The vapor extraction device is on the back of the Cooking chamber guided vertically and has one with the vapor opening of the Corresponding inlet opening. In addition, the pressure channel is above of the cooking space runs horizontally and ends in a vapor or Air outlet panel.

Bei einem bekannten Back- und Bratofen (DE 29 04 389 A1) ist an der Rückseite des Backofens eine Wrasenauslaßöffnung vorgesehen, die mit einer ebenfalls rückwärtigen Öffnung einer über dem Backofen angeordneten Kochmulde strömungstechnisch kom muniziert, von wo aus der durch ein im Inneren des Backofens angeordnetes motorbe triebenes Gebläse nach oben gedrückte Wrasen ins Freie ausströmt bzw. zum Teil von einer mit Abstand oberhalb der Kochmulde angeordneten Dunstabzugshaube abgesaugt werden kann. Hierbei ist auch bei eingeschalteter Dunstabzugshaube eine Beeinträchti gung der Küchenraumluft durch den heißen und fetthaltigen Wrasen sowie eine Konden sation desselben an Küchenmöbeln und dgl. nicht zu verhindern. Bei einem anderen be kannten Wrasenabführungssystem (DE 27 05 395 B2) ist an einer oberen, rückwärtigen Stelle eines Stand herdes eine Auslaßöffnung vorgesehen, mit der sowohl ein von der Backofenmuffel herkommender Wrasenkanal als auch ein oberhalb der Backofenmuffel im Gehäuseinnenraum endender Abluftkanal für die erwärmte Umgebungsluft verbunden ist. Der Standherd besitzt eine obere Abdeckplatte, die einen Hohlraum besitzt, welcher in der hochgeschwenkten Stellung der Abdeckplatte mit der vorgenannten Auslaßöffnung strömungsmäßig gekoppelt ist und in welchem senkrechten Hohlraum das Gemisch aus Wrasen und Umgebungsluft einer mit Abstand oberhalb des Standherdes angeordneten Dunstabzugshaube zugeführt wird. Ein derartiges Wrasenabführsystem ist für die Verwendung bei in Küchenzeilen eingebauten Einbaubacköfen ungeeignet, da ein fest mit dem unmittelbar unterhalb eines Oberschrankes plazierten Backofen verbundener, den vorgenannten Hohlraum bildender Abluftkanal beträchtliche Schwierigkeiten bei der Montage und Demontage des Einbaubackofens bereitet und hierbei die bei Einbaubacköfen gegebenen Erfordernisse bezüglich Wärmeentsorgung an der Ofenperipherie (z.B. bei der Betriebsart "pyrolytische Selbstreinigung") nicht berücksichtigt sind.In a known baking and roasting oven (DE 29 04 389 A1) is on the back of the Oven provided a vapor outlet opening, which also has a rear opening a cooking hob arranged above the oven communicates fluidically, from where the powered by a motorbe arranged inside the oven Blowers pushed upwards emanate to the outside or partly from a distance Above the hob arranged extractor hood can be suctioned off. Here, even when the extractor hood is switched on, there is an impairment of the kitchen air due to the hot and fatty vapors and a condensation of the same Kitchen furniture and the like can not be prevented. In another known vapor evacuation system (DE 27 05 395 B2) is at an upper, rear position of a cooker an outlet opening is provided, with which one coming from the oven muffle Vapor canal as well as an exhaust air duct that ends above the oven muffle in the interior of the housing for the heated ambient air. The standing stove has an upper one Cover plate, which has a cavity, which in the pivoted position of the Cover plate is fluidly coupled to the aforementioned outlet opening and in which vertical cavity the mixture of vapors and ambient air has Distance above the cooker hood is supplied. A Such vapor removal system is for use in built-in kitchen units Built-in ovens unsuitable because one is fixed with the one immediately below an upper cabinet placed oven connected, the aforementioned cavity forming exhaust air duct considerable Difficulties in the assembly and disassembly of the built-in oven and the requirements for heat disposal in built-in ovens on the periphery of the furnace (e.g. in the "pyrolytic self-cleaning" mode) are.

Der Erfindung liegt die Aufgabe zugrunde, eine Anordnung der im Oberbegriff des Pa tentanspruches 1 genannten Art so auszugestalten, daß neben günstiger Montage- und Demontageeigenschaften und ggf. auch Nachrüstbarkeit des Systems "Backofen-Wra senabführung" eine bestmögliche Wärmeentsorgung im Einbaubereich des Backofens erhalten wird.The invention has for its object an arrangement of the claim in the preamble of Pa 1 mentioned type so that in addition to favorable assembly and disassembly properties and, if necessary, retrofitting of the "Oven-Wra senabführung" the best possible heat disposal in the installation area of the oven is obtained.

Diese Aufgabe wird gemäß der Erfindung gelöst durch die im Patentanspruch 1 aufgeführten Maßnahmen.This object is achieved according to the invention by the in claim 1 listed measures.

Durch die mechanische Trennung von Abluftleitung und Backofen ergibt sich die Möglichkeit, unabhängig vom jeweils anderen Systemteil (Backofen bzw. Abluftleitung) eine Montage oder Demontage des Backofens oder der Abluftleitung vorzunehmen. Es besteht z.B. in einfacher Weise die Möglichkeit, einen mit einer hinteren Auslaßöffnung versehenen Backofen nachträglich mit einer solchen Abluftleitung zu versehen, wozu z.B. lediglich die Rückwand des Oberschrankes vorübergehend entfernt werden muß. Umgekehrt kann z.B. zu Reparaturzwecken der Backofen demontiert werden, ohne daß hiervon die Abluftleitung betroffen ist. Gleichzeitig ergibt sich durch diese mechanische Trennung und die lose strömungstechnische Verbindung zwischen den vorgenannten Teilen der Vorteil, daß nicht nur Abluft aus dem Backofen selbst, sondern auch erhitzte Luft aus der Umgebung des Backofens durch die Abluftleitung hindurch abgeführt wird, so daß es auch denkbar ist, einen mit pyrolytischer Selbstreinigungseinrichtung versehenen und in dieser Betriebsart im Muffelinnenraum bis zu 500°C erhitzten Backofen ohne geräteeigenes Kühlsystem zu verwenden, sofern ein Sauggebläse mit entsprechend hoher Saugleistung außerhalb des Backofens im Strömungsweg der Abluft angeordnet ist. In vorteilhatter Weise kann sich hierfür ein separates Gebläse in der Abluftleitung befinden, wobei dieses Gebläse schaltungsmäßig an die Steuereinrichtung des Backofens angeschlossen und zusammen mit Betriebsfunktionen des Backofens an- und ausschaltbar ist. Durch die Plazierung dieses Gebläses hinter dem Oberschrank ergibt sich eine beträchtliche Geräuschdämmung bei Gebläsebetrieb.The mechanical separation of the exhaust air duct and the oven offers the possibility of independent of the other system part (oven or exhaust duct) or disassemble the oven or the exhaust air duct. There is e.g. in a simple way the possibility an oven provided with a rear outlet opening to subsequently provide such an exhaust air duct, why e.g. only the rear wall of the top cabinet temporarily must be removed. Conversely, e.g. for repair purposes the oven can be dismantled without this the exhaust air duct is affected. At the same time it results due to this mechanical separation and the loose flow technology Connection between the aforementioned parts the advantage that not only exhaust air from the oven itself, but also heated air from around the oven through the Exhaust duct is discharged through, so that it is also conceivable is, one with pyrolytic self-cleaning device provided and in this mode in the muffle interior up oven heated to 500 ° C without the device's own cooling system use, if a suction fan with a correspondingly high Suction power outside the oven in the exhaust air flow path is arranged. This can be advantageous a separate fan is located in the exhaust pipe, whereby this fan in terms of circuitry to the control device of the oven and together with operating functions the oven can be switched on and off. Through the Placing this blower behind the top cabinet results considerable noise insulation during fan operation.

Die vorgenannte Abluftleitung kann unmittelbar an einen ins Freie führenden Mauerkasten angeschlossen sein oder aber oberhalb des OberschranKes enden, wobei vorgesehen sein kann, daß im Bereich dieser oberen Abluftmündung ein Fettfilter angeordnet ist, der die Restbestände an fetthaltigen Abluftanteilen des ohnehin schon im Bereich der Auslaßöffnung des Backofens gebildeten fettarmen Luft-/Wrasengemisches auffängt. The aforementioned exhaust air duct can be directly connected to an Free leading wall box can be connected or else end above the top cabinet, where provided can a grease filter in the area of this upper exhaust air outlet is arranged, the remaining stocks of fatty Exhaust air proportions already in the area of the outlet opening of the oven is a low-fat air / vapor mixture catches.

In Figur 1 ist ein sogenannter Einbaubackofen 1 in vereinfachter Weise und schematisch dargestellt, bestehend aus einer beheizbaren Ofenmuffel 2, die mit einer Isolation 3 umgeben ist und deren frontseitige Beschickungsöffnung durch eine Ofentür 4 verschließbar ist. Die Ofenmuffel 2 ist angeordnet innerhalb eines quaderförmigen Backofengehäuses 5, das oberhalb der Ofenmuffel 2 einen Schalterraum 6 besitzt, In dem elektrische oder elektronische Bauelemente 7 und zugeordnete Bedienorgane 8 einer nicht weiter beschriebenen Steuereinrichtung für den Backofen angeordnet sind. Im Bereich der Rückseite des Schalterraumes 6 befindet sich ein ebenfalls nur schematisch angedeutetes Kühlluftgebläse 9, dessen Saugseite indirekt an die die Ofenmuffel 2 umziehenden Hohlräume zwischen Ofenmuffel 2 und Backofengehäuse 5 lufttechnisch angeschlossen ist und dessen Druckseite in einen rückwärtigen Luftabführkanal 10 einmündet, der wiederum an eine an der Rückseite der oberen Begrenzung des Backofengehäuses 5 befindliche Auslaßöffnung 11 angeschlossen ist, welche Auslaßöffnung sich über einen Teil oder über die gesamte Breite des Backofengehäuses 5 erstrecken kann. In den Luftabführkanal mündet ferner ein Wrasenkanal 12 ein, der seinerseits in die Ofenmuffel 2 an deren Rückseite einmündet. Bei Heizbetrieb des Backofens 1, z.B. in der Betriebsart "pyrolytische Selbstreinigung" wird auch zusammen mit der Anwahl der Betriebsart das Kühlluftgebläse 9 eingeschaltet, um dadurch aus dem Umgebungsraum der Ofenmuffel 2 die erwärmte Gehäuseluft in nachbeschriebener Weise durch die Außlaßöffnung 11 hindurch nach außen abzuführen, und zwar zusammen mit dem im Inneren der Ofenmuffel 2 entstehenden heißen und fetthaltigen Wrasen, der insbesondere bei Grillbetrieb des Backofens vermehrt auftritt. Im Bereich des Luftabführkanals 10 wird der Wrasen mit der wesentlich kühleren, vom Kühlluftgebläse 9 angesaugten Gehäuseluft innig vermischt, wobei dieses Wrasen-/Luftgemisch eine deutlich niedrigere Temperatur und eine geringere spezifische Fetthaltigkeit erhält. Aufgrund des bei Betrieb des Kühlluftgebläses 9 im Schalterraum 6 und in den übrigen, die Ofenmuffel 2 umgebenden Hohlräumen erzeugten Unterdrucks fließt kühle Luft von außen durch Luftspalte 13 hindurch in Pfeilrichtung in das Innere des Backofengehäuses 5, umströmt die Ofenmuffel 2 bzw. die thermisch wenig belastbare Steuereinrichtung und wird vom Kühlgebläse 9 angesaugt und in der erläuterten Weise nacn außen abgegeben, wobei auf diese Weise die Wärme aus dem Umgebungsraum der Ofenmuffel 2 abgezogen wird. Beim Ausführungsbeispiel ist der Backofen 1 eingebaut in eine Küchenzeile, d.h. er steht auf einem Unterschrank 14 und über ihm befindet sich ein Oberschrank 15, wobei zwischen Oberkante des Backofens 1 und Oberschrank-Unterkante ein Luftspalt 16 verbleibt.In Figure 1, a so-called built-in oven 1 is simplified Shown way and schematically, consisting of a heatable oven muffle 2, which are surrounded by insulation 3 and the front loading opening through an oven door 4 can be closed. The furnace muffle 2 is arranged within a cuboid oven housing 5, which has a switch room 6 above the muffle 2, In the electrical or electronic components 7 and associated Operating elements 8 of a not described further Control device for the oven are arranged. In the area the back of the switch room 6 is a likewise only schematically indicated cooling air blower 9, the suction side of which indirectly moves to the furnace muffle 2 Cavities between oven muffle 2 and oven housing 5 is connected in terms of ventilation and its pressure side in one rear air discharge duct 10 opens, which in turn to one on the back of the top of the oven body 5 located outlet opening 11 is connected, which outlet opening covers part or all of it Width of the oven housing 5 can extend. In the Air discharge duct also opens into a vapor duct 12 which in turn opens into the oven muffle 2 at the rear. When the oven 1 is operating, e.g. in operating mode "Pyrolytic self-cleaning" is also used together with the cooling air blower 9 is switched on when the operating mode is selected, thereby the from the surrounding area of the furnace muffle 2 heated housing air in the manner described by the To discharge outlet opening 11 to the outside, namely together with the inside of the oven muffle 2 hot and greasy vapors, especially when using the grill of the oven occurs increasingly. In the area of Air discharge duct 10 is the vapor with the much cooler, from the cooling air blower 9 air sucked intimately mixed, this vapor / air mixture a clearly lower temperature and lower specific fat content receives. Because of the operation of the cooling air fan 9 in the counter room 6 and in the rest, the oven muffle 2 surrounding cavities generated negative pressure flows cool air from the outside through air gaps 13 in the direction of the arrow in the interior of the oven housing 5, flows around the Furnace muffle 2 or the thermally unstable control device and is sucked in by the cooling fan 9 and in the explained Were released outside, this way the heat is withdrawn from the surrounding area of the furnace muffle 2 becomes. In the embodiment, the oven 1 is installed into a kitchenette, i.e. he stands on a base cabinet 14 and above it is an upper cabinet 15, with between Upper edge of the oven 1 and lower edge of the upper cabinet an air gap 16 remains.

Wie aus Figur 2 ersichtlich, befindet sich innerhalb der Küchenzeile neben Unterschrank 14, Backofen 1 und Oberschrank 15 ein Hochschrank 17 auf der einen Seite, während sich auf der anderen Seite ein weiterer Unterschrank 14 mit Arbeitsplatte 18 anschließt. Der über dem Backofen 1 befindliche Oberschrank 15 besitzt eine geringere Tiefe als der Backofen 1 und ggf. auch als die übrigen Küchenmöbel, so daß zwischen Rückseite Oberschrank 15 und Stellwand 19 eine Nische 20 mit der Tiefe T von etwa 18 cm verbleibt. In dieser Nische 20 montiert ist eine in Figur 1 nur schematisiert angedeutete Abluftleitung 21, die zumindest im oberen Bereich in Rohrform ausgebildet ist. Diese im übrigen schachtartige Abluftleitung 21 steht nun in loser strömungstechnischer Verbindung mit der Auslaßöffnung 11 des Backofens 1. Dies bedeutet, daß diese Abluftleitung 21 nicht starr und lufttechnisch dicht an die Auslaßöffnung 11 angekoppelt ist, sondern als separater Baustein mit Abstand über der Auslaßöffnung 11 angeordnet ist, wobei vorgesehen ist, daß sich ein elastisches Verbindungsteil 22, z.B. ein trichterartig geneigtes Fangblech des Leitungsschachtes abdichtend an die untere, rückwärtige Kante des Cberschrankes 15 anliegt und ein senkrechtes, verlängertes Verbindungsteil 23 ebenfalls elastisch oder federnd sich an der Rückwand 24 des Backofens 1 ebenfalls abdichtend anliegt. Auf diese Weise steht die Abluftleitung 21 nicht nur mit der Auslaßöffnung 11 in strömungstechnischer Verbindung, sondern auch mit dem Luftspalt 16 sowie mit seitlichen Luftspalten zwischen Backofen 1 und z.B. Hochschrank 17, so daß eine Wärmeentsorgung auch an der Außenperipherie des Backofens 1 stattfindet. Die hierzu notwendige Saugwirkung kann erzielt werden durch die durch das Kühlluftgebläse 9 bewirkte Luftströmung (Pfeilrichtung) in der Abluftleitung und durch die damit verbundene sogenannte Injektorwirkung, die das strömende Medium auf die Hohlräume außerhalb des Backofens 1 ausübt oder aber, gemäß der Darstellung in Figur 1, zusätzlich oder alleine durch ein als Druckgebläse ausgebildetes, separates Gebläse 25, das in der Abluftleitung 21 bzw. an der Abluftleitung mit Wirkung innerhalb der Abluftleitung 21 angeordnet ist.As can be seen from Figure 2, is located within the kitchenette next to base cabinet 14, oven 1 and top cabinet 15 a tall cabinet 17 on one side while on the other side another base cabinet 14 with worktop 18 connects. The one above the oven 1 Upper cabinet 15 has a smaller depth than the oven 1 and possibly also as the other kitchen furniture, so that between Rear wall cabinet 15 and partition 19 with a niche 20 the depth T of about 18 cm remains. In this niche 20 mounted is only schematically indicated in Figure 1 Exhaust duct 21, at least in the upper region in the form of a tube is trained. This, moreover, a shaft-like exhaust duct 21 is now in loose fluid communication with the outlet opening 11 of the oven 1. This means that this exhaust duct 21 is not rigid and air technology is coupled closely to the outlet opening 11, but as a separate building block at a distance above the outlet opening 11 is arranged, it being provided that there is an elastic Connection part 22, e.g. a funnel-like incline Sealing plate of the cable duct sealing against the lower one abuts the rear edge of the cabinet 15 and a vertical, extended connecting part 23 also elastic or resiliently on the rear wall 24 of the oven 1 as well fits tightly. In this way, the exhaust air line stands 21 not only with the outlet opening 11 in fluidic Connection, but also with the air gap 16 and with side air gaps between oven 1 and e.g. Tall cabinet 17 so that heat is also removed from the Outer periphery of the oven 1 takes place. The necessary for this Suction can be achieved through the Cooling air blower 9 caused air flow (arrow direction) in the exhaust air duct and through the so-called Injector action that the flowing medium on the cavities exercises outside the oven 1 or, as shown in Figure 1, additionally or alone by an as Pressure fan formed, separate fan 25 which in the Exhaust duct 21 or on the exhaust duct with effect within the exhaust pipe 21 is arranged.

Für den Fall, daß sowohl ein separates Gebläse 25 als auch ein Kühlluftgebläse 9 vorgesehen ist, sollte die Lüfterleistung des separaten Gebläses 25 größer sein als diejenig des Kühlluftgebläses 9, um einen Rückstau des aus der Auslaßöffnung 11 austretenden Luftgemisches und ein Ausströmen zwischen die Spalte der Küchenzeile zu verhindern. Sofern nur das separate Gebläse 25 vorgesehen ist, ist ein derartiger Rückstau nicht zu befürchten, sofern in der Abluftleitung 21 oberhalb des Gebläses 25 kein wesentliches Strömungshindernis vorhanden ist. Diese Abluftleitung 21 kann unmittelbar an einen sogenannten Mauerkasten (in der Zeichnung nicht dargestellt) z.B. in der Stellwand 19 angeschlossen sein. Für diesen Fall ist es vorteilhaft, wenn in der Abluftleitung 21 oberhalb des Gebläses 25 eine ebenfalls nicht dargestellte Rückstauklappe vorgesehen Ist, da der Mauerkasten ein Strömungshindernis darstellen kann. Um einen synchronen Betrieb von Backofen 1 und Gebläse 25 sicherzustellen ist vorgesenen, daß dieses Gebläse über ebenfalls nicht dargestellte elektrische Leitungen mit der Steuereinrichtung des Backofens 1 in Verbindung steht und durch z.B. das Bedienorgan 8 gleichzeitig mit der Backofenbeheizung an- und ausschaltbar Ist. In the event that both a separate fan 25 and a cooling air blower 9 is provided, the fan power of the separate fan 25 may be larger than that of the Cooling air blower 9 to back up the from the outlet opening 11 emerging air mixture and an outflow between to prevent the column of the kitchenette. If only the separate blower 25 is provided is one Backwater is not to be feared, provided that 21 no significant flow obstacle above the fan 25 is available. This exhaust line 21 can immediately to a so-called wall box (not in the drawing shown) e.g. be connected in the partition 19. In this case, it is advantageous if in the exhaust duct 21 above the fan 25, also not shown Backflow flap is provided because of the wall box can be an obstacle to flow. To a synchronous Operation of oven 1 and fan 25 must be ensured provided that this blower is also not shown electrical lines with the control device of the Oven 1 is connected and e.g. the control element 8 can be switched on and off simultaneously with the oven heating Is.

In Figur 2 ist die Einbaulage der Abluftleitung 21 verdeutlicht, während Figur 3 wesentliche Einzelheiten der Abluftleitung 21 zeigt. Man erkennt, daß die Abluftleitung 21 im unteren Bereich als schmaler und langgestreckter Schacht 26 ausgebildet ist, der am unteren Ende sich trichterartig erweitert, wofür der vorgenannte Verbindungsteil 22 sowie Seitenteile 27 dienen. Auf den Schacht 26 aufgesetzt ist das mittels eines Elektromotors angetriebene Gebläse 25, dessen Saugseite an den Schacht 26 angeschlossen ist und dessen Druckseite mit einem z.B. elastischen Rohr 28 verbunden ist, das den oberen Teil der Abluftleitung 21 darstellt. Über die elektrische Leitung 29 ist das Gebläse 25 mit der Steuereinrichtung des Backofens 1 verbindbar. Strichpunktiert angedeutet ist der vor dem Gebläse 25 liegende Oberschrank 15.The installation position of the exhaust air line 21 is illustrated in FIG. 2, while Figure 3 essential details of the exhaust duct 21 shows. It can be seen that the exhaust line 21 in lower area as a narrow and elongated shaft 26 is formed, which widens like a funnel at the lower end, for which the aforementioned connecting part 22 and side parts 27 serve. It is placed on the shaft 26 by means of an electric motor driven fan 25, the Suction side is connected to the shaft 26 and its Print page with e.g. elastic tube 28 is connected that represents the upper part of the exhaust duct 21. About the electrical line 29 is the blower 25 with the control device of the oven 1 connectable. Dash-dotted lines is the upper cabinet 15 located in front of the fan 25.

Beim Ausführungsbeispiel gemäß Figur 4 ist wiederum ein Einbaubackofen 1 unterhalb eines Oberschrankes 15 und oberhalb eines Unterschrankes 14 plaziert und weist wiederum gemäß Figur 1 eine rückseitige Auslaßöffnung 11 auf. Zum Unterschied zum Ausführungsbeispiel gemäß Figur 1 ist hierbei die Nische 30 zwischen Stellwand 19 und Rückseite Oberschrank 15 weniger tief als diejenige gemäß Figur 1. Entsprechend ist hierbei die Abluftleitung 21' durchgehend in Form eines schmalen Schachtes, z.B. entsprechend des Schachtes 26 gemäß Figur 3 ausgebildet, wobei auch hier am unteren Schachtende vorzugsweise elastische oder federnde Verbindungsteile 22' bzw. 23' vorgesehen sind. Die Abluftleitung 21' endet in Höhe der Oberkante des Oberschrankes 15. Oberhalb dieses freien Leitungsendes ist eine Fettfiltereinrichtung 31 angeordnet, gebildet z.B. durch einen von einer Rolle 32 abspulbaren fettabsorbierenden Papierfilter 33, der versteckt an der Hinterseite des Oberschrankes 15, z.B. auf einem Träger 34 verläuft und sehr leicht bei Sättigung entfernbar ist. Bei diesem Ausführungsbeispiel erfolgt die Abführung der Abluft aus dem Backofengehäuse 5 und aus dessen Peripherie ausschließlich durch das Kühlluftgebläse 9. Hierbei ist es vorteilhaft, wenn die Abluftleitung 21' mit geringem Abstand zur Rückseite des Oberschrankes 15 angeordnet ist.In the embodiment shown in Figure 4 is again a built-in oven 1 below an upper cabinet 15 and above a base cabinet 14 is placed and in turn points in accordance 1 shows a rear outlet opening 11. The difference the exemplary embodiment according to FIG. 1 is Niche 30 between partition 19 and rear of upper cabinet 15 is less deep than that according to FIG. 1 here the exhaust line 21 'continuously in the form of a narrow shaft, e.g. corresponding to the shaft 26 according to Figure 3 formed, also here at the lower end of the shaft preferably elastic or resilient connecting parts 22 ' and 23 'are provided. The exhaust air line 21 'ends in height the upper edge of the upper cabinet 15. Above this free A fat filter device 31 is arranged at the end of the line, formed e.g. by one that can be unwound from a roll 32 grease-absorbing paper filter 33, which is hidden on the Rear of top cabinet 15, e.g. on a support 34 runs and is very easy to remove when saturated. At In this embodiment, the exhaust air is removed from the oven housing 5 and from its periphery exclusively through the cooling air fan 9. It is advantageous here if the exhaust duct 21 'is a short distance away is arranged to the rear of the upper cabinet 15.
