Description

Die Erfindung betrifft ein Gargerät mit einer Tür.The invention relates to a cooking appliance with a door.

Aus der EP 1 801 505 A2 ist ein Gargerät bekannt, bei welchem türseitig ein Strömungskanal zwischen beabstandet zu einer Türaußenscheibe angeordneten weiteren Innenscheiben ausgebildet ist. Seitlich zu der der Türaußenscheibe nächstgelegenen weiteren Innenscheibe ist gegenüber einem oberen Ende dieser Innenscheibe nach unten versetzt und auf der der Türaußenscheibe abgewandten Seite eine Strömungsöffnung ausgebildet, in der eine Dichtung eingesetzt ist.From the EP 1 801 505 A2 a cooking appliance is known in which the door side, a flow channel is formed between spaced apart from a door outer pane arranged further inner panes. Laterally to the door outer disc closest further inner disc is offset from an upper end of the inner pane down and formed on the side facing away from the door outer pane, a flow opening in which a seal is inserted.

Aus der EP 1 022 517 A1 ist ein Gargerät bekannt, bei dem eine Tür eine Mehrzahl von Scheiben aufweist, und oberhalb von Innenscheiben eine Öffnung eines Strömungskanals ausgebildet ist. Oberhalb dieser Öffnung ist auf der Außenseite der Tür eine Dichtung angeordnet. Die Tür umfasst auf dieser Außenseite eine weitere Dichtung, die jedoch umlaufend ausgebildet ist und mit einem unteren Abschnitt in einem unteren Bereich der Tür verläuft.From the EP 1 022 517 A1 a cooking appliance is known in which a door has a plurality of disks, and above inner disks, an opening of a flow channel is formed. Above this opening, a seal is arranged on the outside of the door. The door comprises on this outside another seal, which is, however, formed circumferentially and extends with a lower portion in a lower portion of the door.

Bei Gargeräten, insbesondere einem Backofen, ist es bekannt, dass eine Tür zum Verschließen eines Garraums mehrere Türscheiben aufweist, die beabstandet zueinander und parallel verlaufend angeordnet sind. Durch ein derartiges Scheibenpaket, das darüber hinaus auch zumindest eine zwischen der Türaußenscheibe und der Türinnenscheibe liegende Türzwischenscheibe aufweisen kann, soll insbesondere auch erreicht werden, dass die im Garraum vorherrschende Temperatur nicht vollständig auf die Türaußenscheibe übertragen wird. Zudem ist es gewünscht, einerseits den Garraum vor unnötigem Wärmeenergieverlust mittels der Tür zu schützen, andererseits die Türaußenscheibe nicht zu heiß werden zu lassen. Dazu ist es bekannt, dass mittels eines oder mehrerer Gebläse im Haushaltsgerät eine Luftströmung erzeugt wird, die durch die jeweiligen Zwischenbereiche der Scheiben in der Tür bedarfsgerecht gefördert wird, um die oben genannten Aspekte erreichen zu können. Das Ansaugen der Luft kann dabei von außerhalb des Gargeräts erfolgen, wobei durch entsprechende türseitige und geräteseitige Strömungskanäle die Luftströmung geleitet wird. Bei gegenwärtig bekannten Ausgestaltungen ist bei geschlossener Tür eine ungewünschte Schnittstelle zwischen dem türseitigen Strömungskanal und dem geräteseitigen Strömungskanal, die benachbart zueinander liegen, gegeben. Dies ist im Hinblick auf Strömungsoptimierung, Kühlwirkung und auch im Hinblick auf das Absaugen von Wrasen aus dem Garraum über diese Schnittstelle nachteilig.In cooking appliances, in particular an oven, it is known that a door for closing a cooking chamber has a plurality of door windows, which are spaced apart from each other and arranged to extend in parallel. By such a disk package, which may also have at least one lying between the door outer pane and the door inner pane door intermediate disc, should also be achieved in particular that the temperature prevailing in the cooking chamber is not completely transferred to the door outer pane. In addition, it is desired, on the one hand to protect the oven from unnecessary loss of heat by means of the door, on the other hand, the door outer pane does not get too hot. For this purpose, it is known that by means of one or more fans in the household appliance, an air flow is generated, which is promoted by the respective intermediate areas of the discs in the door needs, in order to achieve the above aspects. The suction of the air can take place from outside the cooking appliance, wherein the air flow is passed through corresponding door-side and device-side flow channels. In presently known embodiments, with the door closed, an undesirable interface between the door-side flow channel and the device-side flow channel adjacent lie to each other, given. This is disadvantageous in terms of flow optimization, cooling effect and also with regard to the extraction of vapors from the cooking chamber via this interface.

Es ist Aufgabe der vorliegenden Erfindung, ein Gargerät zu schaffen, bei welchem die Schnittstelle zwischen einem türseitigen und einem geräteseitigen Strömungskanal verbessert ist.It is an object of the present invention to provide a cooking appliance in which the interface between a door-side and a device-side flow channel is improved.

Diese Aufgabe wird durch ein Gargerät gemäß Anspruch 1 gelöst.This object is achieved by a cooking appliance according to claim 1.

Die Erfindung betrifft ein Gargerät mit einem Garraum, der durch eine Tür verschließbar ist. In besonders hervorzuhebender Weise ist vorgesehen, dass die Dichtung, die an der Tür angeordnet ist, und als erste Dichtung bezeichnet werden kann, im geschlossenen Zustand der Tür unmittelbar an einer einen geräteseitigen Strömungskanal begrenzenden Wand anliegt und ein, insbesondere dichtendes, Strömungskanalkoppelelement zwischen dem türseitigen Strömungskanal und dem geräteseitigen Strömungskanal bildet. Gerade im geschlossenen Zustand der Tür ist durch diese türseitige erste Dichtung quasi ein Strömungskanaladapter gebildet, der durch seine vorzugsweise vorgesehene Flexibilität auch ein möglichst großflächiges Anliegen der Dichtung an dem Gehäuse des Gargeräts ermöglicht, sodass gerade an dieser Schnittstelle zwischen der Tür und dem Gehäuse und somit den einander zugewandten Strömungskanälen der Tür einerseits und des Gehäuses andererseits keine Leckage auftritt. Dies hat dahingehend erhebliche Vorteile, dass auch keine Einsaugung von Luft, beispielsweise aus dem Garraum, über diese Schnittstelle in den türseitigen Strömungskanal und/oder den geräteseitigen Strömungskanal bzw. gehäuseseitigen Strömungskanal auftritt.The invention relates to a cooking appliance with a cooking chamber which can be closed by a door. In a particularly emphasized manner, it is provided that the seal, which is arranged on the door, and can be referred to as the first seal, in the closed state of the door rests directly against a wall bounding a device-side flow channel and a, in particular sealing, Strömungskanalkoppelelement between the door side Flow channel and the device-side flow channel forms. Especially in the closed state of the door quasi a flow channel adapter is formed by this door-side first seal, which allows a preferably large-scale concerns the seal on the housing of the cooking appliance through its preferably provided flexibility, so just at this interface between the door and the housing and thus the facing flow channels of the door on the one hand and the housing on the other hand, no leakage occurs. This has considerable advantages in that even no intake of air, for example from the cooking chamber, occurs via this interface in the door-side flow channel and / or the device-side flow channel or housing-side flow channel.

Es ist vorgesehen, dass ein dem Garraum näher liegender Abschnitt der türseitigen ersten Dichtung eine Abdichtung des Strömungskanals zum Garraum bildet und eine weitere, insbesondere zweite, türseitige Dichtung, zur Garraumabdichtung beabstandet zur ersten Dichtung garraumzugewandt angeordnet ist. Dadurch kann das Absaugen von Wrasen aus dem Garraum besonders effizient verhindert werden.It is envisaged that a portion of the door-side first gasket closer to the cooking chamber forms a seal of the flow channel to the cooking chamber and a further, in particular second, door-side gasket, spaced Garraumabgewandt arranged for Garraumabdichtung to the first seal. As a result, the extraction of vapors from the oven can be prevented particularly efficient.

Die Tür umfasst eine Türaußenscheibe und zumindest eine weitere Scheibe, die beabstandet zur Türaußenscheibe angeordnet ist, sodass zwischen der Türaußenscheibe und der weiteren Scheibe ein türseitiger Strömungskanal ausgebildet ist. An einem oberen Ende der weiteren Scheibe ist zwischen der Türaußenscheibe und der weiteren Scheibe eine Strömungskanalöffnung ausgebildet. An dieser Strömungskanalöffnung ist eine Dichtung angeordnet. Durch ein derartiges zusätzliches Element wird die Schnittstelle im Hinblick auf die Strömungswirkung optimiert.The door comprises an outer door panel and at least one further disc, which is arranged at a distance from the door outer panel, so that a door-side flow channel is formed between the outer door panel and the further disc. At one Upper end of the other disc is formed between the outer door panel and the other disc, a flow channel opening. At this flow channel opening a seal is arranged. Such an additional element optimizes the interface with regard to the flow effect.

Es ist vorgesehen, dass die Dichtung vollständig umlaufend um die Strömungskanalöffnung angeordnet ist.It is envisaged that the seal is arranged completely circumferentially around the flow channel opening.

Des Weiteren ist vorgesehen, dass an dem oberen Ende der weiteren Scheibe zwischen der Türaußenscheibe und der weiteren Scheibe ein Abdeckelement angeordnet ist, welches die Strömungskanalöffnung aufweist. Mechanische Stabilität bezüglich der beiden Scheiben einerseits und der Gestaltung der Strömungskanalöffnung andererseits ist dadurch erreicht. Darüber hinaus lässt sich durch dieses Abdeckelement auch eine möglichst großflächige und mechanisch stabile Anbringung der Dichtung erzielen. Die Dichtung muss somit nicht direkt an eine der Scheiben angebracht werden.Furthermore, it is provided that at the upper end of the further disc between the outer door panel and the other disc a cover member is arranged, which has the flow channel opening. Mechanical stability with respect to the two discs on the one hand and the design of the flow channel opening on the other hand is achieved. In addition, can be achieved by this cover also the largest possible and mechanically stable attachment of the seal. The seal does not have to be directly attached to one of the discs.

Darüber hinaus kann mittels dieses Abdeckelements die Orientierung und Lage der Strömungskanalöffnung spezifisch ausgebildet und dauerhaft gehalten werden.In addition, the orientation and position of the flow channel opening can be specifically designed and permanently held by means of this cover.

Es ist vorgesehen, dass ein Grundkörper der Dichtung an der Außenwand des Abdeckelements angeordnet ist. Dadurch lässt sich eine besonders hervorzuhebende Anbindung an das Gehäuse des Gargeräts erreichen.It is provided that a base body of the seal is arranged on the outer wall of the cover. This makes it possible to achieve a particularly emphasized connection to the housing of the cooking appliance.

Insbesondere ist die Dichtung aus einem elastischen und reversibel verformbaren Material, beispielsweise einem Elastomer oder Thermoplast. Die oben genannten Vorteile werden dadurch nochmals begünstigt. Darüber hinaus ist eine derartige Ausgestaltung verschleißarm und möglichst gewichtsreduziert, sodass das Gewicht der Tür unwesentlich und im Vergleich zu den anderen Komponenten vernachlässigbar erhöht ist.In particular, the seal is made of an elastically and reversibly deformable material, for example an elastomer or thermoplastic. The advantages mentioned above are thereby further favored. In addition, such a design is low-wear and reduced in weight as possible, so that the weight of the door is negligible and negligible compared to the other components.

Des Weiteren ist die Dichtung unmittelbar im Bereich eines die Strömungskanalöffnung begrenzenden Rands des Abdeckelements angeordnet. Dadurch kann ein möglichst bündiger Übergang zwischen dem türseitigen Strömungskanal und der Dichtung erreicht werden, sodass auch hier keine unnötigen sprunghaften Querschnittsveränderungen des Strömungskanals in der Tür im Vergleich zu dem Querschnitt der Dichtung auftreten. Die in dem türseitigen Strömungskanal erzeugte Luftströmung kann dadurch in dem Abschnitt, in dem die türseitige Dichtung dann angeordnet ist, entsprechend weiter geführt werden, ohne dass große Verwirbelungen oder dergleichen auftreten würden.Furthermore, the seal is arranged directly in the region of an edge of the cover element bounding the flow channel opening. As a result, the most flush possible transition between the door-side flow channel and the seal can be achieved, so that no unnecessary sudden changes in cross-section of the flow channel in the door occur here in comparison to the cross section of the seal. The air flow generated in the door-side flow channel can thereby in the Section, in which the door-side seal is then arranged to be continued accordingly without large turbulence or the like would occur.

Insbesondere ist das Gargerät ein Backofen.In particular, the cooking appliance is an oven.

Diese als Strömungskanalkoppelelement dienende erste Dichtung gewährleistet auch, dass bei geschlossener Tür ein optimierter Luftdurchsatz erreicht wird und insbesondere die Temperatur der Türaußenscheibe effizienter auf das gewünschte Maß reduziert werden kann, ohne dass die Drehzahl des Gebläses erhöht werden müsste oder gar ein Gebläse mit stärkerer Saugleistung verwendet werden muss. In umgekehrter Sicht betrachtet, ist es durch die Erfindung nun auch gewährleistet, dass im Hinblick auf die Saugleistung schwächere Gebläse im Vergleich zum Stand der Technik eingesetzt werden können, da gerade an der Schnittstelle zwischen der Tür und dem Gehäuse keine derartigen unerwünschten Leckageströme auftreten.This first seal serving as a flow channel coupling element also ensures that when the door is closed, an optimized air flow rate is achieved and, in particular, the temperature of the door outer pane can be reduced more efficiently to the desired level, without the speed of the fan having to be increased or even using a fan with greater suction power must become. Viewed in the opposite direction, it is now also ensured by the invention that with regard to the suction power weaker blower compared to the prior art can be used, since no such undesirable leakage currents occur at the interface between the door and the housing.

In Fig. 1 ist in einer schematischen Längsschnittdarstellung und somit in einem vertikalen Schnitt ein als Backofen 1 ausgebildetes Haushaltsgerät gezeigt. Der Backofen 1 umfasst einen Garraum 2, der durch Wände einer Muffel 3 begrenzt ist. Frontseitig weist die Muffel 3 eine Beschickungsöffnung auf, die durch eine Tür 4 verschließbar ist. In der gezeigten Darstellung in Fig. 1 ist die Tür 4 im vollständig geschlossenen Zustand gezeigt. Die Tür 4 umfasst im Ausführungsbeispiel eine außenliegende Türaußenscheibe 5, eine dem Garraum nächstliegende Türinnenscheibe 6 und zwischen der Türaußenscheibe 5 und der Türinnenscheibe 6 liegende Türzwischenscheiben 7 und 8. Die vier Scheiben 5 bis 8 sind jeweils parallel zueinander und beabstandet angeordnet, sodass jeweils zwischen zwei benachbarten Scheiben ein Zwischenraum ausgebildet ist.In Fig. 1 is shown in a schematic longitudinal sectional view and thus in a vertical section designed as a baking oven 1 household appliance. The oven 1 includes a cooking chamber 2, which is bounded by walls of a muffle 3. On the front side, the muffle 3 has a charging opening, which can be closed by a door 4. In the illustration shown in Fig. 1 the door 4 is shown in the fully closed state. In the exemplary embodiment, the door 4 comprises an outer door outer pane 5, a door inner pane 6 closest to the cooking space, and door intermediate windows 7 and 8 located between the outer door pane 5 and the inner door pane 6. The four panes 5 to 8 are each arranged parallel to one another and at a distance, so that in each case between two adjacent disc a gap is formed.

Wie zu erkennen ist, ist die Türaußenscheibe 5 im Hinblick auf ihre Höhe (y-Richtung) größer ausgebildet als die weiteren Scheiben 6 bis 8.As can be seen, the outer door panel 5 is designed to be larger in size with respect to its height (y-direction) than the further panels 6 to 8.

Benachbart zu den oberen Rändern der Scheiben 6 bis 8 ist ein Abdeckelement 9 angeordnet, welches die zwischen den Scheiben 5 bis 8 gebildeten Zwischenräume von oben abdeckt.Adjacent to the upper edges of the discs 6 to 8, a cover member 9 is arranged, which covers the intermediate spaces formed between the discs 5 to 8 from above.

Durch die Zwischenräume zwischen den Scheiben 5 bis 8 sind auch Strömungszonen bzw. Strömungskanäle gebildet, durch welche mittels eines Gebläses 10 erzeugte Luftströmungen hindurchströmen können. Dadurch wird einerseits eine Kühlung der außenliegenden Scheiben, insbesondere der Türaußenscheibe 5, erreicht. Andererseits wird die Luftzirkulation und -strömung so bedarfsgerecht durchgeführt, dass insbesondere die Türinnenscheibe 6 nur gering gekühlt wird, um diesbezüglich nicht unnötige Wärmeenergie aus dem Garraum 2 zu entnehmen.Through the spaces between the discs 5 to 8, flow zones or flow channels are formed through which air flows generated by means of a blower 10 can flow. As a result, on the one hand, cooling of the outer panes, in particular the door outer pane 5, is achieved. On the other hand, the air circulation and flow is performed as needed, that in particular the door inner pane 6 is only slightly cooled, in order not to remove unnecessary heat energy from the cooking chamber 2 in this regard.

In Fig. 2 ist eine vergrößerte Darstellung des Teilausschnitts 11 in Fig. 1 gezeigt. Türseitig ist im Bereich des Abdeckelements 9 ein türseitiger Strömungskanal 11 gebildet. In dem Abdeckelement 9 sind gemäß der Darstellung in Fig. 3 drei Strömungskanalöffnungen 12, 13 und 14 gebildet. In Fig. 3 ist diesbezüglich eine Ansicht auf eine Innenseite 15 der Türaußenscheibe 5 gezeigt, wobei gemäß der Darstellung in Fig. 1 die Innenseite 15 den weiteren Scheiben 6 bis 8 zugewandt ist. Fig. 3 zeigt somit quasi eine Ansicht aus dem Garraum 2 heraus auf die Tür 4.In Fig. 2 is an enlarged view of the partial section 11 in Fig. 1 shown. Door side, a door-side flow channel 11 is formed in the region of the cover 9. In the cover 9 are shown in FIG Fig. 3 three flow channel openings 12, 13 and 14 are formed. In Fig. 3 in this regard, a view is shown on an inner side 15 of the door outer pane 5, wherein, as shown in FIG Fig. 1 the inner side 15 faces the further disks 6 to 8. Fig. 3 Thus, as it were, shows a view from the cooking chamber 2 onto the door 4.

Bei der in Fig. 2 gezeigten Darstellung mit geschlossener Tür 4 liegen die Strömungskanalöffnungen 12 bis 14 benachbart zu einer Strömungskanalöffnung 16 eines gerätegehäuseseitigen Strömungskanals 17. Dieser Strömungskanal 17 ist somit in einem Gehäuse 18 des Backofens 1 angeordnet. Wie in der Darstellung gemäß Fig. 2 zu erkennen ist, ist zwischen der Tür 4 und dem Gehäuse 18 ein Freiraum 19 ausgebildet.At the in Fig. 2 shown with closed door 4 are the flow channel openings 12 to 14 adjacent to a flow channel opening sixteenth a device housing-side flow channel 17. This flow channel 17 is thus arranged in a housing 18 of the oven 1. As in the illustration according to Fig. 2 can be seen, a clearance 19 is formed between the door 4 and the housing 18.

In diesem Freiraum 19 ist eine erste türseitige Dichtung 20 angeordnet. Sie ist dabei an einer Außenwand 21 des Abdeckelements 9 angeordnet und gemäß der Darstellung in Fig. 3 als vollständig geschlossene umlaufende Dichtung 20 ausgebildet. Die Strömungskanalöffnungen 12 bis 14 werden somit durch diese erste Dichtung 20 quasi umrahmt.In this space 19, a first door-side seal 20 is arranged. It is arranged on an outer wall 21 of the cover 9 and as shown in FIG Fig. 3 formed as a completely closed circumferential seal 20. The flow channel openings 12 to 14 are thus quasi framed by this first seal 20.

Wie darüber hinaus gemäß der Darstellung in Fig. 2 zu erkennen ist, ist die Dichtung 20 auch an dem Gehäuse 18 bei geschlossener Tür 4 anliegend angeordnet, sodass der Freiraum 19 im Bereich der Strömungskanalöffnungen 12 bis 14 durch diese Dichtung 20 abgedichtet ist und somit die Dichtung 20 auch als Strömungskanalkoppelelement bzw. Adapter zwischen den Strömungskanälen 11 und 17 dient.As in addition, as shown in Fig. 2 can be seen, the seal 20 is also arranged on the housing 18 with the door closed 4, so that the free space 19 is sealed in the region of the flow channel openings 12 to 14 through this seal 20 and thus the seal 20 as Strömungskanalkoppelelement or adapter between the Flow channels 11 and 17 is used.

Des Weiteren ist gemäß der Darstellung in Fig. 2 zu erkennen, dass die Dichtung 20 mit ihren einander zugewandten Innenseiten 20a auf Höhe mit unmittelbar benachbart zu einem die Strömungskanalöffnungen 12 bis 14 begrenzenden Rand 22 des Abdeckelements 9 angeordnet ist. Die Breite bzw. die Querschnittsöffnung der Dichtung 20 entspricht somit dem Strömungsquerschnitt der Strömungskanalöffnungen 12 bis 14.Furthermore, as shown in FIG Fig. 2 to recognize that the seal 20 is arranged with their mutually facing inner sides 20a at the level with immediately adjacent to the flow channel openings 12 to 14 limiting edge 22 of the cover 9. The width or the cross-sectional opening of the seal 20 thus corresponds to the flow cross-section of the flow channel openings 12 to 14.

Darüber hinaus ist vorgesehen, dass beabstandet zu dieser ersten Dichtung 20 eine weitere Dichtung 23 an der Tür 4 angeordnet ist, die näher zum Garraum als die erste Dichtung 20 positioniert ist. Sie ist insbesondere ebenfalls an dem Abdeckelement 9 angeordnet. Gerade durch den unteren horizontal verlaufenden Abschnitt der ersten Dichtung 20 und diese weitere zweite Dichtung 23 wird somit eine Leckageströmung von dem Garraum 2 in den Strömungskanal 11 und/oder 17 insbesondere über den Freiraum 19 verhindert.In addition, it is provided that, spaced from this first seal 20, a further seal 23 is arranged on the door 4, which is positioned closer to the cooking chamber than the first seal 20. It is also arranged in particular on the cover 9. Just by the lower horizontally extending portion of the first seal 20 and this further second seal 23 thus a leakage flow from the cooking chamber 2 in the flow channel 11 and / or 17 is prevented in particular via the space 19.
