Abstract

The oven (3) is heated by electric tubular elements (6) and enclosed in an outer casing (1) together with a cooling fan (23) which expels air from the duct (25) downwards across the outer door (13). Air and vapour within the oven are circulated by a fan (8) mounted on the rear wall behind a screen (7) and driven by a motor (9). The constriction introduced by a deflector (31) creates a suction effect drawing vapour through a heat-resistant plastic tube (27) across the cavity (14) between the doors. The mouth (29) of the tube opens into the air duct below the deflector which is aerodynamically shaped to ensure vortex-free flow.

Description

Die vorliegende Erfindung betrifft einen Backofen mit einer durch eine Ofentür verschließbaren Ofenmuffel, die mit Abstand von einem Ofengehäuse umgeben ist, wobei für aus dem Gehäuse austretende Kühlluft durch die Ofentür eine Ausblasstrecke führt, in die ein Wrasenkanal der Ofentür mündet, der strömungstechnisch mit der Backofenmuffel in Verbindung steht.The present invention relates to an oven with an oven muffle which can be closed by an oven door and which is surrounded at a distance from an oven housing, wherein for cooling air emerging from the housing, a blow-out path leads through the oven door, into which a vapor channel of the oven door opens, which flows in terms of flow with the oven muffle communicates.

Ein derartiger Backofen ist bekannt aus der EP 0 482 602 A1, wobei im oberen Türrand eine Luftaustrittsöffnung in Verbindung mit einem im Ofengehäuse angeordneten Luftleitelement vorgesehen ist für die Abführung der in der Umgebung der Ofenmuffel erwärmten oder direkt aus der Ofenmuffel kommenden erhitzten Luft. Dabei ist anstelle eines Kühlluftgebläses eine Luftfangschale vorgesehen, die mit ihrer offenen Schalenseite nach unten gerichtet und dem Gehäuseraum sowie gegebenenfalls einer Wrasenauslaßöffnung Zugewandt ist. Der Wrasen wird im Griffbereich in die Nähe der Luftaustrittsöffnung geleitet und vermischt sich dort mit der von der Luftfangschale her kommenden Luft. Vorteilhafterweise ist auf ein Abführen des Wrasens durch eine Öffnung der Backofenmuffel ins Innere des Ofengehäuses und von dort nach außen verzichtet, womit insbesondere ein aufwendiges Abdichten der Wrasenführung im Ofengehäuse entfallen kann. Nachteilig bei dem aus der EP 04882 602 A 1 bekannten Backofen ist jedoch zum einen, daß der Wrasen in das Innere des Backofens gedrückt werden kann. Zum anderen ist die Luft, die aus dem zwischen der Backofenmuffel und dem Ofengehäuse befindlichen Raum nach außen abströmen will, durch den von der Ofentür herausströmenden Wrasen stark behindert, was zu einem Wärmestau führen kann. Weiterhin kann sich der Wrasen nachteiligerweise unmittelbar im Bereich der Tür bzw. des Türgriffs niederschlagen, da der Luftstrom der aus dem Gehäuse abströmenden Luft zu schwach ist, um den Wrasen gezielt und schnell vom Gerät wegzuleiten.Such an oven is known from EP 0 482 602 A1, an air outlet opening being provided in the upper door edge in connection with an air guiding element arranged in the oven housing for the removal of the heated air that is heated in the vicinity of the oven muffle or that comes directly from the oven muffle. In this case, instead of a cooling air blower, an air collecting bowl is provided which, with its open bowl side, points downward and faces the housing space and, if appropriate, a vapor outlet opening. The vapor is directed in the handle area near the air outlet opening and mixes there with that of the Air catcher coming air. Advantageously, the vapors are not discharged through an opening of the oven muffle into the interior of the oven housing and from there to the outside, with the result that, in particular, complex sealing of the vapor guide in the oven housing can be dispensed with. A disadvantage of the oven known from EP 04882 602 A1 is, on the one hand, that the steam can be pressed into the interior of the oven. On the other hand, the air that wants to flow outwards from the space between the oven muffle and the oven housing is severely hampered by the vapors flowing out of the oven door, which can lead to heat build-up. Furthermore, the vapor can disadvantageously precipitate directly in the area of the door or the door handle, since the air flow of the air flowing out of the housing is too weak to direct the vapor away from the device quickly and specifically.

Aufgabe der vorliegenden Erfindung ist es deshalb, einen Backofen bereitzustellen, bei dem die beim Austreten des Wrasens aus dem Backofen auftretenden Probleme verringert sind.It is therefore an object of the present invention to provide an oven in which the problems which occur when the vapors exit the oven are reduced.

Erfindungsgemäß ist dies dadurch erreicht, daß in dem Ofengehäuse ein Lüfter angeordnet ist, der die Kühlluft durch die Ausblasstrecke aus dem Ofengehäuse durch die Ofentür drückt, und daß in der Ausblasstrecke im Bereich der Einmündung des Wrasenkanals in die Ausblasstrecke eine Engstelle ausgebildet ist, wodurch die ausgeblasene Kühlluft mittels Injektorwirkung Wrasen aus dem Wrasenkanal bzw. der Backofenmuffel saugt. Der aus der Ofenmuffel durch die Ofentür in die Ausblasstrecke strömende Wrasen wird durch die Kühlluft schnell und gezielt aus dem Backofen geleitet. Das Eindringen des Wrasens in das Ofengehäuseinnere ist ausgeschlossen, die Verschmutzung des Backofens im Frontbereich durch Wrasen ist deutlich verringert. Durch die Injektorwirkung infolge des geringfügigen Unterdruckes ist gewährleistet, daß ausreichend Wrasen aus der Backofenmuffel abgesaugt wird. Zudem ist in diesem Bereich das Ausblasen des Wrasens durch die beschleunigte Kühlluft verbessert.According to the invention, this is achieved in that a fan is arranged in the furnace housing, which presses the cooling air through the outlet section from the furnace housing through the furnace door, and in that a constriction is formed in the outlet section in the region of the confluence of the vapor channel and the outlet section, as a result of which Blown-out cooling air sucks vapors out of the vapor duct or the oven muffle by means of an injector effect. The vapors flowing out of the oven muffle through the oven door into the outlet section are quickly and specifically directed out of the oven by the cooling air. The intrusion of fumes in the oven interior is excluded, the pollution of the oven in the front area by fumes is significantly reduced. The injector effect due to the slight negative pressure ensures that sufficient vapors are extracted from the oven muffle. In addition, the blowing out of the vapor is improved in this area by the accelerated cooling air.

Bevorzugterweise ist die Engstelle durch ein Luftleitblech gebildet, das den Wrasen in die Strömungsrichtung der ausgeblasenen Kühlluft lenkt. Der Wrasen wird also strömungstechnisch günstig ohne wesentliche Wirbelbildung in die Kühlluftströmung gezielt eingeleitet. Dabei kann auf die Anordnung eines röhrenförmigen Wrasenkanals innerhalb der Ausblasstrecke verzichtet werden. Durch diesen würde der Luftaustrittsquerschnitt für die Kühlluft veringert und damit das Ausblasen der Kühlluft behindert, was die Kühlleistung herabsetzen würde. Zudem wäre ein zusätzliches Bauteil aus hochtemperaturbeständigem Material für den Wrasenkanal in der Ausblasstrecke erforderlich. Der ausströmende Wrasen wird weiterhin daran gehindert, an der Unterseite einer häufig in diesem Bereich angeordneten Strömungsblende zu kondensieren, durch ein Luftpolster, das die ausströmende Kühlluft zwischen Wrasen und Strömungsblende bildet. Gemäß einer bevorzugten Ausführungsform dichtet das Luftleitblech zumindest den der ausgeblasenen Kühlluft zugewandten Randbereich der Wrasenöffnung des Wrasenkanals ab und erstreckt sich kapuzenförmig in die Ausblasstrecke. Dabei ist das Luftleitblech sowohl auf seiner Innenseite als auch auf seiner Außenseite aerodynamisch günstig im Sinne einer wirbelfreien Strömung ausgestaltet, um zum einen Wirbelbildung an den Rändern des Luftleitblechs beim Anströmen durch die ausgeblasene Kühlluft zu verhindern und um zum anderen das Einleiten des Wrasenstroms in den Kühlluftstrom strömungstechnisch günstig zu gestalten. Weder durch das Anströmen des Luftleitbleches durch die Kühlluft noch durch das Einleiten des Wrasens in den Kühlluftstrom wird das Ausblasen der Kühlluft behindert oder die Kühlluft unkontrolliert aus dem Ofen gewirbelt. Dadurch sind der Wirkungsgrad des Kühlsystems und das Ausblasen des Wrasens aus dem Backofen verbessert.The constriction is preferably formed by an air baffle that directs the vapors in the direction of flow of the blown-out cooling air. The vapor is thus introduced into the cooling air flow in a fluidly favorable manner without substantial eddy formation. The arrangement of a tubular vapor channel within the blow-out section can be dispensed with. This would reduce the air outlet cross section for the cooling air and thus hinder the blowing out of the cooling air, which would reduce the cooling capacity. In addition, an additional component made of high-temperature-resistant material would be required for the vapor duct in the blow-out section. The outflowing vapors are further prevented from condensing on the underside of a flow orifice, which is often arranged in this area, by an air cushion which forms the outflowing cooling air between vapors and the flow orifice. According to a preferred embodiment, the air baffle seals at least the edge area of the vapor opening of the vapor channel facing the blown-out cooling air and extends into the blow-out section in a hood-like manner. The air baffle is designed to be aerodynamically favorable on the inside as well as on the outside in the sense of a vortex-free flow, in order firstly to form vortices at the edges of the air baffle when it flows against the blown out air To prevent cooling air and to make the flow of vapor into the cooling air flow favorable in terms of flow technology. The blowing out of the cooling air is not impeded or the cooling air is whirled out of the oven in an uncontrolled manner, neither by the flow of air through the cooling air nor by the introduction of the vapor into the cooling air flow. This improves the efficiency of the cooling system and the blowing of the vapors out of the oven.

Das Einhüllen des aus der Ofentür austretenden Wrasenstroms mit einem Kühlluftstrom wird an den beiden Seitenbereichen des Wrasenstroms dadurch verbessert, daß sich das Luftleitblech nur über einen Teil der Breite der Ausblasstrecke erstreckt und insbesondere den Querschnitt dieser in deren Seitenbereichen nicht verringert. Da dadurch auch eine Wirbelbildung in den Randbereichen der ausströmenden Luft verhindert ist, kann ausgeschlossen werden, daß die austretende heiße Luft beispielsweise zu den kritischen Stirnkanten gegebenenfalls vorhandener Anstellmöbel strömt und diese unzulässig aufheizt. Weiterhin ist ein dadurch möglicher "Kühlluftstrom-Kurzschluß" verhindert, der darin bestünde, daß die zu den Stirnkanten strömende erwärmte aus dem Ofeninneren ausgeblasene Kühlluft in diesem Bereich anstelle kühler Luft durch das Kühlluftgebläse wieder in den Backofen zu Kühlzwecken gesaugt wird.The enveloping of the vapor stream emerging from the furnace door with a cooling air stream is improved on the two side regions of the vapor stream in that the air baffle extends only over part of the width of the blow-out section and in particular does not reduce the cross-section of the latter in the side regions thereof. Since this also prevents the formation of eddies in the edge regions of the outflowing air, it can be excluded that the hot air escaping, for example, flows to the critical front edges of any furniture which may be present and heats them up inadmissibly. Furthermore, a possible "cooling air flow short circuit" is prevented, which would consist in the fact that the heated cooling air flowing out to the front edges and blown out of the interior of the oven in this area is sucked back into the oven for cooling purposes instead of cool air by the cooling air blower.

Gemäß einer bevorzugten Ausführungsform ist eine Strömungsblende, ein Bestandteil der Tür bildend an dieser befestigt, wobei in der Strömungsblende sowohl die Ausblasstrecke als auch die Einmündung des Wrasenkanals ausgebildet sind. Dadurch entfällt ein umständliches Ausblasen der Kühlluft bzw. des Wrasens durch die eigentliche Backofentür. Eine evtl. auftretende Verschmutzung ist deshalb auch nur auf die Strömungsblende beschränkt. Weiterhin kann die Strömungsblende günstigerweise dazu verwendet werden, die Ausblasstrecke und die entsprechenden Öffnungen vor dem Betrachter zu verbergen. Gemäß einer bevorzugten Ausführungform verdeckt die Strömungsblende zumindest die Luftaustrittsöffnung und ragt über die Gehäusefrontseite. Dadurch kann die Kühlluft bzw. der Wrasen gezielt aus dem Bereich der Gehäusefrontseite weggeleitet werden. Besonders günstig ist es dabei, wenn die Strömungsblende am freien Ende dachförmig nach unten gezogen ist. So sind infolge der Strömungsgeschwindigkeit der austretenden Luft auch oberhalb der Strömungsblende an der Gehäusefrontseite angeordnete Bedien- und Anzeigeelemente vor dem Wrasen bzw. der heißen Luft geschützt.According to a preferred embodiment, a flow diaphragm, forming part of the door, is fastened to the door, both the outlet section and the mouth of the vapor duct being formed in the flow diaphragm. This eliminates the cumbersome blowing out of the cooling air or of steaming through the actual oven door. Any contamination that may occur is therefore only limited to the flow orifice. Furthermore, the flow orifice can advantageously be used to hide the blowout section and the corresponding openings from the viewer. According to a preferred embodiment, the flow orifice covers at least the air outlet opening and projects over the front of the housing. As a result, the cooling air or vapors can be directed away from the area of the housing front. It is particularly favorable if the flow orifice is pulled downward at the free end in a roof shape. As a result of the flow velocity of the exiting air, operating and display elements arranged above the flow orifice on the front of the housing are also protected from the vapors or the hot air.

Gemäß einer bevorzugten Ausführungsform weist die Ofentür zwischen dem äußeren Türblatt und dem Türboden einen Konvektions-Hohlraum auf, der zumindest zum Teil in die Ausblasstrecke einmündet. Durch eine gegebenenfalls vorliegende Injektorwirkung sorgt die ausgeblasene Kühlluft zusätzlich für eine Verbesserung der Durchlüftung der Backofentür und damit für eine Verringerung deren Fronttemperatur. Wenn eine Tür Kühlluft-Austrittsöffnung in Strömungsrichtung im Anschluß an den Bereich der Wrasenöffnung in die Ausblasstrecke einmündet, bildet die Tür-Kühlluft ein unteres Luftpolster, wodurch der Wrasen im Fall der Strömungsblende und des Luftleitbleches allseitig von nicht fetthaltiger Kühlluft im wesentlichen wirbelfrei eingehüllt und aus der Strömungsblende bzw. dem Ofen geführt wird. Die Verschmutzung der Tür bzw. der Strömungsblende in diesem Bereich ist dadurch weiter veringert.According to a preferred embodiment, the oven door has a convection cavity between the outer door leaf and the door base, which at least partially opens into the outlet section. If there is an injector effect, the blown-out cooling air also improves the ventilation of the oven door and thus reduces its front temperature. If a door of cooling air outlet opening flows into the outlet section in connection with the area of the vapor opening, the door cooling air forms a lower air cushion, whereby the vapor in the case of the flow shield and the air baffle is enveloped and swirled on all sides by non-greasy cooling air, essentially in a vortex-free manner the flow orifice or the furnace is guided. This further reduces contamination of the door or the flow orifice in this area.

Um auch insbesondere für den Selbstreinigungsbetrieb geeignet zu sein, ist in dem Wrasenkanal ein Regelelement, insbesondere eine von einem Thermoelement gesteuerte Klappe angeordnet, das den Wrasenkanal bei hohen Temperaturen selbsttätig verschließt.In order to also be particularly suitable for self-cleaning operation, a control element, in particular a flap controlled by a thermocouple, is arranged in the vapor channel, which automatically closes the vapor channel at high temperatures.

Die Beschickungsöffnung der Ofenmuffel 3 ist verschließbar durch eine Ofentür 11, bestehend aus einem Türboden 12 mit einer darin befestigten Glasscheibe und einem äußeren Türblatt 13 in Form einer transparenten Glasscheibe. Zwischen dem Türboden 12 und dem Türblatt 13 ist ein Konvektionshohlraum 14 mit Lufteintrittsöffnungen unten und nachfolgend genauer beschriebenen Luftöffnungen oben gebildet. Am oberen Rand der Ofentür 11 ist eine Griffleiste 15 befestigt, die eine über die Gehäusefrontseite hinausragende Strömungsblende 17 besitzt. Diese weist einen dachförmig nach unten gezogenen Ansatz 18 auf. Die Strömungsblende 17 erstreckt sich über die gesamte Breite des Backofens und einer über der Griffleiste 15 am Ofengehäuse befestigten Bedienblende 19 mit Anzeige- und Bedienelementen 20. In den beiden Seitenbereichen des Griffteils 15 ist in diesen jeweils eine Luftaustrittsöffnung 21 vorgesehen, die als langgezogener horizontaler Schlitz ausgebildet ist, der von der Strömungsblende 17 überdeckt ist. Diese beiden Lüftungsschlitze 17 sind zum Ausblasen der Kühlluft völlig ausreichend, wie später erläutert ist. Oberhalb der Backofenmuffel 3 ist innerhalb des Ofengehäuses 1 ein Kühllüfter 23 angeordnet, der in an sich bekannter Weise Kühlluft von außen in das äußere Ofengehäuse 1 saugt. An die Ausblasseite des Kühllüfters 23 schließt sich im Ofengehäuse 1 eine kanalförmige Ausblasstrecke 25 an, die in die Luftaustrittsöffnung 21 der Griffleiste 15 mündet und in dieser seine Fortsetzung als Ausblasstrecke 25 findet, wie in Fig. 3 näher erläutert ist. Im Inneren der Ofentür 11 erstreckt sich in deren oberen Bereich zwischen der Backofenmuffel 3 und der Ausblasstrecke 25 ein röhrenförmiger Wrasenkanal 27 aus hochtemperaturbeständigem Kunststoffmaterial. Durch diesen wird beim Garvorgang Wrasen aus dem eigentlichen Backraum nach außen gedrückt, ohne in den Konvektionshohlraum 14 der Tür 11 gelangen zu können. Um den Garraum ansonsten im wesentlichen luftdicht zu verschließen, umzieht eine Dichtung 28 die Innenseite des Türbodens 12. Im Bereich einer Einmündung 29 des Wrasenkanals 27 in die Ausblasstrecke 25 ist ein Luftleitblech 31 angeordnet, das eine sich im wesentlichen horizontal erstreckende Wrasenöffnung 30 der Griffleiste 15 bzw. des Wrasenkanals 27 in die Ausblasstrecke 25 nun im wesentlichen vertikal liegend verschiebt. Zugleich ist durch das Luftleitblech 31 eine Engstelle 32 in der Ausblasstrecke 25 gebildet. In Strömungsrichtung im Anschluß an die Wrasenöffnung 30 ist zwischen der Griffleiste 15 und dem äußeren Türblatt 13 eine Tür-Kühlluft-Austrittsöffnung 33 gebildet.The oven according to the figures is designed as a so-called built-in oven and has an outer oven housing 1 with which it rests on a base plate 2 of a piece of kitchen furniture not shown. Also connected to the side walls of the outer oven housing 1 are kitchen display units (not shown). In the interior of the furnace housing 1 there is a cuboid, metallic furnace muffle 3, only indicated schematically, with a muffle flange 4 moving around a loading opening and a muffle flange 4 3 surrounding insulation 5. The oven muffle 3 or the cooking space contains electrical heating elements 6 in the form of a tubular heater and behind a baffle 7 an impeller 8 which is driven by a fan motor 9. The loading opening of the oven muffle 3 can be closed by an oven door 11, consisting from a door base 12 with a glass pane fastened therein and an outer door leaf 13 in the form of a transparent glass pane. Between the door base 12 and the door leaf 13, a convection cavity 14 is formed with air inlet openings at the bottom and air openings described in more detail below. At the upper edge of the oven door 11, a handle bar 15 is attached, which has a flow diaphragm 17 protruding beyond the housing front. This has an extension 18 which is pulled down in a roof shape. The flow orifice 17 extends over the entire width of the oven and an operating panel 19 with display and operating elements 20, which is attached to the oven housing above the handle bar 15. An air outlet opening 21 is provided in each of the two side areas of the handle part 15, which serves as an elongated horizontal slot is formed, which is covered by the flow orifice 17. These two ventilation slots 17 are completely sufficient for blowing out the cooling air, as will be explained later. A cooling fan 23 is arranged above the oven muffle 3 within the oven housing 1 and draws cooling air from the outside into the outer oven housing 1 in a manner known per se. On the outlet side of the cooling fan 23, a duct-shaped outlet section 25 adjoins the furnace housing 1, which opens into the air outlet opening 21 of the handle strip 15 and is continued in this section as an outlet section 25, as is explained in more detail in FIG. 3. Inside the furnace door 11 extends in the upper area between the oven muffle 3 and the blow-out section 25 are a tubular vapor duct 27 made of high-temperature-resistant plastic material. Through this, vapors are pressed outwards from the actual baking chamber during the cooking process, without being able to get into the convection cavity 14 of the door 11. In order to otherwise close the cooking space essentially airtight, a seal 28 moves around the inside of the door base 12. In the region of an opening 29 of the vapor duct 27 into the blow-out section 25, an air baffle 31 is arranged which has a vapor opening 30 of the handle strip 15 which extends essentially horizontally or of the vapor channel 27 in the blow-out section 25 is now displaced essentially vertically. At the same time, a narrow point 32 is formed in the blow-out section 25 by the air baffle 31. In the flow direction following the vapor opening 30, a door cooling air outlet opening 33 is formed between the handle strip 15 and the outer door leaf 13.

Gemäß Fig. 3 ist ein Abschnitt des Backofens stark schematisiert dargestellt, um das Strömen der verschiedenen Luft- bzw. Wrasenmassen mit Strömungspfeilen besser veranschaulichen zu können. Dabei ist der ausgeblasene Kühlluftstrom mit 35, der Wrasenstrom mit 36 und der Tür-Kühlluftstrom mit 37 bezeichnet. Bei geschlossener Ofentür 11 bläst der Kühllüfter 23 (nicht gezeigt) die Kühlluft 35 durch die im Ofengehäuse 1 ausgebildete Ausblasstrecke 25 zur Luftaustrittsöffnung 21 der Strömungsblende 17. Die Ausblasstrecke 25 findet ihre Fortsetzung in der Strömungsblende 17. Dabei ist die Ausblasstrecke 25 an ihrer Oberseite durch die eigentliche Strömungsblende 17, an ihrer Unterseite durch eine Bodenplatte 41 der Griffleiste 15 und an ihren beiden Seiten durch jeweils einen Seitensteg 43 der Griffleiste 15 begrenzt (Fig.4). Im Anschluß an die Luftaustrittsöffnung 21 ist auf der Bodenplatte 41 der Griffleiste 15 ein Luftleitblech 31 befestigt, das die Engstelle 32 bildend, in die Ausblasstrecke 25 ragt. Dadurch wird die aus dem Gehäuse 1 geblasene Kühlluft in diesem Bereich beschleunigt, was zu einem geringfügigen Druckabfall in der Luftströmung führt, und somit zum einen der Wrasen 36 aus der Backofenmuffel 3 durch den Wrasenkanal 27 und zum anderen die Tür-Kühlluft 37 aus dem Konvektionshohlraum 14 in die Ausblasstrecke 25 gesaugt. Das Luftleitblech 31 sitzt dazu auf der schlitzförmigen Wrasenöffnung 30, die in der Bodenplatte 41 ausgebildet ist und bei auf der Ofentür 11 montierter Griffleiste 15 die eigentliche Ausblasöffnung für den Wrasenkanal 27 darstellt. Das Luftleitblech 31 verschließt den der Strömung zugewandten längsseitigen sowie die schmalseitigen Randbereiche der Wrasenöffnung 30 und erstreckt sich kapuzenförmig nach vorne wölbend, im Sinne einer wirbelfreien Strömung strömungstechnisch günstig in die Ausblasstrecke 25. Dabei ist eine Innenseite 45 des Luftleitblechs 31 in Strömungsrichtung gleichmäßig nach vorne oben gekrümmt entsprechend einer Außenseite des Luftleitblechs 31. In ihren Seitenabschnitten 47 ist das Luftleitblech 31 gleichmäßig gekrümmt bis auf die Bodenplatte 41 heruntergezogen. Der Querschnitt der Ausblasstrecke 25 ist durch das Luftleitblech 31 geringfügig verringert, während in der zweiten Luftaustrittsöffnung der Griffleiste 15 (nicht gezeigt) eine Querschnittsverringerung lediglich zum Ansaugen von Tür-Kühlluft vorgesehen ist. Weiterhin ist das Luftleitblech 31 strömungsgünstig ausgeformt, wodurch insgesamt das Austreten des Kühlluftstroms 35 und damit die Kühlung des Backofens begünstigt ist.According to FIG. 3, a section of the oven is shown in a highly schematic manner in order to better illustrate the flow of the various air or vapor masses using flow arrows. The blown-out cooling air flow is designated 35, the vapor flow 36 and the door cooling air flow 37. When the furnace door 11 is closed, the cooling fan 23 (not shown) blows the cooling air 35 through the outlet section 25 formed in the oven housing 1 to the air outlet opening 21 of the flow orifice 17. The outlet section 25 is continued in the flow orifice 17. The outlet section 25 is through at the top the actual flow orifice 17, delimited on its underside by a base plate 41 of the grip strip 15 and on both sides by a respective side web 43 of the grip strip 15 (Fig.4). Following the air outlet opening 21, an air baffle 31 is fastened on the base plate 41 of the grip strip 15 and projects into the blowout section 25, forming the constriction 32. As a result, the cooling air blown out of the housing 1 is accelerated in this area, which leads to a slight pressure drop in the air flow, and thus on the one hand the vapors 36 from the oven muffle 3 through the vapors duct 27 and on the other hand the door cooling air 37 from the convection cavity 14 sucked into the blowout section 25. For this purpose, the air baffle 31 sits on the slit-shaped vapor opening 30, which is formed in the base plate 41 and, when the handle strip 15 is mounted on the oven door 11, represents the actual outlet opening for the vapor channel 27. The air baffle 31 closes the longitudinal and narrow edge regions of the vapor opening 30 facing the flow and extends hood-like arching forward, in the sense of a vortex-free flow, aerodynamically favorable in the blowout section 25. In this case, an inside 45 of the air baffle 31 is evenly upward in the direction of flow curved corresponding to an outside of the air baffle 31. In its side sections 47, the air baffle 31 is evenly curved down to the base plate 41. The cross section of the blow-out section 25 is slightly reduced by the air baffle 31, while in the second air outlet opening of the handle bar 15 (not shown) a reduction in cross section is provided only for drawing in door cooling air. Furthermore, the air baffle plate 31 is aerodynamically shaped, so that overall the cooling air flow 35 and thus the cooling of the oven is favored.

Infolge der Anordnung des Zusammenströmens der drei Luftströme 35, 36, 37 ist der Wrasenstrom 36 allseitig und insbesondere unten und oben von durch den Kühlluftstrom 35 und den Tür-Kühlluftstrom 37 gebildete Luftpolster eingehüllt. Der gesamte Luftstrom wird nach schräg unten weg von der Gehäusefrontseite geblasen. Im Wrasenkanal 27 ist eine gesteuerte Klappe 49 angeordnet, die den Wrasenkanal 27 beispielsweise beim pyrolytischen Selbstreinigungsbetrieb verschließt.As a result of the arrangement of the confluence of the three air flows 35, 36, 37, the vapor flow 36 is enveloped on all sides and in particular below and above by air cushions formed by the cooling air flow 35 and the door cooling air flow 37. The entire air flow is blown off obliquely downwards from the front of the housing. A controlled flap 49 is arranged in the vapor channel 27 and closes the vapor channel 27, for example, during pyrolytic self-cleaning operation.
