Description

Die Erfindung betrifft ein Hausgerät zum Zubereiten von Lebensmitteln, welches einen Garraum aufweist, der durch eine Muffel begrenzt ist, und ein außerhalb des Garraums angeordnetes Gebläse aufweist, welches zur Erzeugung eines Kühlluftstroms ausgebildet ist. Darüber hinaus umfasst das Hausgerät eine Lampe, welche zur Beleuchtung des Garraums angeordnet ist.The invention relates to a domestic appliance for preparing food, which has a cooking chamber which is delimited by a muffle, and has a fan arranged outside the cooking chamber, which is designed to generate a cooling air flow. In addition, the household appliance comprises a lamp which is arranged to illuminate the cooking chamber.

Ein derartiges Hausgerät ist beispielsweise aus der DE 198 33 774 A1 bekannt.Such a household appliance is for example from the DE 198 33 774 A1 known.

Darüber hinaus ist aus der DE 297 18 343 U1 ein Herd mit einem Kühlluftgebläse und einer Lampe zum Beleuchten des Garraums bekannt. Die Lampe ist an einer Rückseite der Muffel angeordnet und über einen von einem Hauptkanal abzweigenden Nebenkanal eines Kühlluftkanals mit Kühlluft über den Nebenkanal zur Lampe geleitet.In addition, from the DE 297 18 343 U1 a stove with a cooling fan and a lamp for illuminating the cooking chamber known. The lamp is arranged on a rear side of the muffle and routed via a branching off from a main channel auxiliary channel of a cooling air duct with cooling air via the auxiliary channel to the lamp.

Diese Ausgestaltung erfordert im Bereich der Rückseite mehr Bauraum und Platzbedarf für den zusätzlichen Nebenkanal. Darüber hinaus ist die Kühlwirkung eingeschränkt und zusätzliche Bauteile sind erforderlich.This design requires more space and space required for the additional secondary channel in the back. In addition, the cooling effect is limited and additional components are required.

Es ist Aufgabe der vorliegenden Erfindung, ein Hausgerät zum Zubereiten von Lebensmitteln zu schaffen, bei dem die Kühlung einer Lampe verbessert werden kann. Insbesondere soll dies bauteilreduziert erfolgen.It is an object of the present invention to provide a domestic appliance for preparing food, in which the cooling of a lamp can be improved. In particular, this should be done reduced component.

Diese Aufgabe wird durch ein Hausgerät, welches die Merkmale nach Anspruch 1 aufweist, gelöst.This object is achieved by a domestic appliance having the features of claim 1.

Ein erfindungsgemäßes Hausgerät zum Zubereiten von Lebensmitteln umfasst einen Garraum, welcher durch eine Muffel begrenzt ist. Darüber hinaus weist das Hausgerät ein Gebläse auf, welches außerhalb des Garraums angeordnet ist, und welches zur Erzeugung eines Kühlluftstroms ausgebildet ist. Des Weiteren umfasst das Hausgerät zumindest eine Lampe, welche zur Beleuchtung des Garraums angeordnet ist. Das Hausgerät umfasst darüber hinaus einen Hauptkanal zur Kühlluftführung und einen Nebenkanal zur Kühlluftzuführung zu der Lampe. In einer Begrenzungswand des Nebenkanals ist eine geneigte Ablenkplatte angeordnet. Durch diese Ausgestaltung kann eine wesentlich gezieltere und dosiertere Luftzuführung zur Lampe ermöglicht werden. Die Kühlwirkung wird dadurch deutlich verbessert.An inventive household appliance for preparing food comprises a cooking chamber, which is limited by a muffle. In addition, the domestic appliance has a fan, which is arranged outside the cooking chamber, and which is designed to generate a cooling air flow. Furthermore, the household appliance includes at least one lamp which is arranged to illuminate the cooking chamber. The domestic appliance further comprises a main channel for cooling air flow and a secondary channel for cooling air supply to the lamp. In a boundary wall of the sub-channel an inclined baffle plate is arranged. By this configuration, a much more targeted and metered air supply to the lamp can be made possible. The cooling effect is thereby significantly improved.

Vorzugsweise ist die Ablenkplatte in einer Deckenwand des Nebenkanals angeordnet. Dadurch kann die zielgerichtete Kühlluftfokussierung nochmals verbessert werden.Preferably, the baffle plate is arranged in a ceiling wall of the secondary channel. As a result, the targeted cooling air focusing can be further improved.

Vorzugsweise bildet die Ablenkplatte ein zum vorderen Rand des Nebenkanals nach vorne überstehendes Dach, wodurch sich eine besonders hervorzuhebende präzise Strömungsrichtung der Kühlluft zur Lampe ergibt.Preferably, the baffle forms a roof projecting forward to the front edge of the secondary channel, which results in a particularly emphasized precise flow direction of the cooling air to the lamp.

Insbesondere ist die Ablenkplatte einstückig mit der Deckenwand ausgebildet. Durch eine derartige Ausgestaltung kann eine Bauteileinsparung erzielt werden und darüber hinaus eine mechanisch stabile Anbringung der Ablenkplatte gewährleistet werden. Montagetoleranzen im Vergleich zu mehrteiligen Ausgestaltungen können dadurch vermieden werden.In particular, the baffle is formed integrally with the ceiling wall. By such a configuration, a component saving can be achieved and, moreover, a mechanically stable attachment of the baffle plate can be ensured. Mounting tolerances compared to multi-part designs can be avoided.

Vorzugsweise ist die Deckenwand des Nebenkanals einstückig mit der Deckenwand des Hauptkanals ausgebildet. Auch dadurch wird eine Bauteilreduzierung erreicht und die positionelle Anordnung der Komponenten zueinander ist toleranzfrei und dauerhaft bestehend.Preferably, the ceiling wall of the secondary channel is formed integrally with the ceiling wall of the main channel. Also, a component reduction is achieved and the positional arrangement of the components to each other is tolerance-free and permanent.

Vorzugsweise ist vorgesehen, dass die Ablenkplatte derart geneigt ist, dass der Kühlluftstrom direkt auf die Lampe gerichtet ist. Gerade dann, wenn die Anbringung der Lampe im Hinblick auf ihre örtliche Position etwas unterhalb des Gebläses und etwas unterhalb des Nebenkanals angeordnet ist, wird durch diese Augestaltung eine verbesserte Anströmung der Lampe mit Kühlluft erreicht.It is preferably provided that the baffle plate is inclined such that the cooling air flow is directed directly at the lamp. Just when the attachment of the lamp is arranged with respect to their local position slightly below the fan and slightly below the secondary channel, an improved flow of the lamp is achieved with cooling air through this Augestaltung.

Vorzugsweise ist die Ablenkplatte als eine Prägung in der Begrenzungswand ausgebildet. Durch diese Ausgestaltung kann eine einfache und schnelle Herstellung gewährleistet werden und die Ablenkplatte ist quasi in der Begrenzungswand bereits bei der Herstellung der Begrenzungswand integral einbringbar.Preferably, the baffle plate is formed as an embossment in the boundary wall. This design ensures a simple and fast production be and the baffle plate is virtually integrally introduced in the boundary wall already in the production of the boundary wall.

Vorzugsweise ist der Hauptkanal und der Nebenkanal in einem Winkel größer 90°, insbesondere größer 100° und kleiner 150° zueinander angeordnet. Die Luftströmung sowohl im Hauptkanal als auch im Nebenkanal ist daher zumindest bereichsweise jeweils über die größte Strömungsstrecke horizontal orientiert und der Hauptkanal und der Nebenkanal erstrecken sich zumindest bereichsweise horizontal aber in unterschiedliche Richtungen. Dadurch kann eine sehr flach bauende Ausgestaltung ermöglicht werden, die zum einen eine ausreichende Kühlung der Komponenten über den Hauptkanal und eine ausreichende Abführung der erwärmten Kühlluft nach außen, als auch eine ausreichende zuverlässige Kühlung der Lampe gewährleistet werden.Preferably, the main channel and the secondary channel at an angle greater than 90 °, in particular greater than 100 ° and less than 150 ° to each other. The air flow in both the main channel and the secondary channel is therefore oriented horizontally, at least in regions, over the largest flow path, and the main channel and the secondary channel extend horizontally but at least partially in different directions. As a result, a very flat design can be made possible, which ensures sufficient cooling of the components via the main channel and adequate discharge of the heated cooling air to the outside, as well as sufficient reliable cooling of the lamp.

Vorzugsweise ist eine Bodenwand des Hauptkanals einstückig mit der Bodenwand des Nebenkanals ausgebildet. Auch diese Ausgestaltung trägt positiv zur Bauteilreduzierung bei.Preferably, a bottom wall of the main channel is formed integrally with the bottom wall of the sub-channel. This embodiment also contributes positively to component reduction.

Vorzugsweise ist die Bodenwand oberhalb der Deckenwand der Muffel und beabstandet dazu angeordnet. Insbesondere ist die Lampe in der Deckenwand der Muffel angeordnet. Gerade bei einer derartig spezifischen Ausgestaltung, bei der sich der Nebenkanal in vertikaler Richtung betrachtet zumindest bereichsweise etwas oberhalb der Lampe erstreckt, kann durch die Ablenkplatte die geeignete Strömungsführung zur Lampe hin erreicht werden. Durch die Anbringung der Lampe in der Deckenwand kann eine besonders umfassende Ausleuchtung des Garraums erreicht werden.Preferably, the bottom wall is above the top wall of the muffle and spaced therefrom. In particular, the lamp is arranged in the top wall of the muffle. Especially in such a specific embodiment, in which the side channel extends at least in some areas slightly above the lamp when viewed in the vertical direction, the suitable flow guidance towards the lamp can be achieved through the deflection plate. By attaching the lamp in the ceiling wall a particularly comprehensive illumination of the cooking chamber can be achieved.

Insbesondere ist das Hausgerät zum Durchführen eines Pyrolysebetriebs ausgebildet und weist somit eine Pyrolysefunktion auf. Da gerade bei einer derartigen Betriebsart sehr hohe Temperaturen im Garraum auftreten, und diesbezüglich eine sehr hohe Temperaturbeaufschlagung der Lampe einher gehen kann, ist gerade hier die ausreichende und zuverlässige Kühlung besonders wichtig.In particular, the domestic appliance is designed to carry out a pyrolysis operation and thus has a pyrolysis function. Since especially in such an operating mode very high temperatures occur in the oven, and in this regard can go hand in hand with a very high temperature exposure of the lamp, the adequate and reliable cooling is particularly important here.

In den Figuren werden gleiche oder funktionsgleiche Elemente mit den gleichen Bezugszeichen versehen.In the figures, identical or functionally identical elements are provided with the same reference numerals.

In Fig. 1 ist in einer Draufsicht ein Hausgerät gezeigt, welches als Backofen ausgebildet ist. Der Backofen 1 umfasst einen Garraum 2 (Fig. 2), welcher durch eine Muffel 3 (Fig. 2) begrenzt ist. Die Muffel 3 weist eine frontseitige Beschickungsöffnung auf, welche durch eine Tür 4 verschließbar ist. Die Tür 4 umfasst einen Griff 5, mittels welchem diese gegriffen und entsprechend geöffnet und geschlossen werden kann. Darüber hinaus ist über der Tür 4 eine Bedienblende 6 ausgebildet, welche beispielhaft Bedienelemente 7 und 8 aufweist. Zwischen der Bedienblende 6 und der Tür 4 sind Luftaustrittsöffnungen ausgebildet, durch welche erwärmte Kühlluft 9 nach außen tritt. Der Backofen 1 ist zum Pyrolysebetrieb ausgebildet.In Fig. 1 is shown in a plan view of a household appliance, which is designed as a baking oven. The oven 1 comprises a cooking chamber 2 ( Fig. 2 ) which passes through a muffle 3 ( Fig. 2 ) is limited. The muffle 3 has a front-side charging opening, which can be closed by a door 4. The door 4 comprises a handle 5, by means of which it can be grasped and opened and closed accordingly. In addition, a control panel 6 is formed above the door 4, which has control elements 7 and 8 by way of example. Between the control panel 6 and the door 4 air outlet openings are formed, through which heated cooling air 9 passes to the outside. The oven 1 is designed for pyrolysis.

Oberhalb der Muffel 3 ist ein Gebläse 10 angeordnet, welches Kühlluft von außerhalb des Backofens 1 einsaugt und einen entsprechenden Kühlluftstrom zum Kühlen der Komponenten erzeugt.Above the muffle 3, a fan 10 is arranged, which sucks in cooling air from outside the oven 1 and generates a corresponding cooling air flow for cooling the components.

Dazu ist direkt im Anschluss an das Gebläse 10 ein Hauptkanal 11 ausgebildet, in welchem die Kühlluft strömt und dann frontseitig erwärmt aus dem Backofen 1 austritt. Das Gebläse 10 mit seinem Lüfter 12 ist so angeordnet, dass der Lüfter 12 über eine senkrecht zur Figurenebene orientierte Achse drehbar ist.For this purpose, directly after the fan 10, a main channel 11 is formed, in which the cooling air flows and then exits the front side heated from the oven 1 exits. The fan 10 with its fan 12 is arranged so that the fan 12 is rotatable about an axis oriented perpendicular to the plane of the figure.

Darüber hinaus umfasst der Backofen 1 einen Nebenkanal 13, welcher im Hinblick auf die Orientierung mit seiner Hauptachse B in einem Winkel α zur Hauptachse C des Hauptkanals 11 orientiert ist, welcher zwischen 100° und 150° beträgt.In addition, the oven 1 comprises a side channel 13, which is oriented with respect to the orientation with its main axis B at an angle α to the main axis C of the main channel 11, which is between 100 ° and 150 °.

Im hinteren Bereich des Garraums 2 ist in einer Deckenwand 14 der Muffel 3 eine Lampe 15 angeordnet, welche zur Ausleuchtung des Garraums 2 ausgebildet ist. Wie zu erkennen ist, ist der Nebenkanal 13 mit einem deutlich kleineren Strömungsquerschnitt als de Hauptkanal 11 ausgebildet.In the rear region of the cooking chamber 2, a lamp 15 is arranged in a ceiling wall 14 of the muffle 3, which is designed to illuminate the cooking chamber 2. As can be seen, the secondary channel 13 is formed with a significantly smaller flow cross-section than the main channel 11.

Durch die Drehung des Lüfterrads 12 wird eine Strömung der Kühlluft erzeugt, welche sich sowohl nach vorne in den Hauptkanal 11 begibt als auch in den Nebenkanal 13 strömt, wodurch dann die Lampe 15 gekühlt wird.By the rotation of the fan 12, a flow of cooling air is generated, which both goes forward in the main channel 11 and flows into the secondary channel 13, whereby the lamp 15 is then cooled.

In Fig. 2 ist eine Schnittdarstellung entlang der Schnittlinie A in Fig. 1 gezeigt. Es ist zu erkennen, dass der Hauptkanal 11 eine Deckenwand 16 aufweist, welche einstückig mit einer Deckenwand 17 des Nebenkanals 13 ausgebildet ist. Des Weiteren umfasst der Hauptkanal 11 eine Bodenwand 18, welche ebenfalls einstückig mit einer Bodenwand 19 des Nebenkanals 13 ausgebildet ist.In Fig. 2 is a sectional view taken along the section line A in Fig. 1 shown. It can be seen that the main channel 11 has a ceiling wall 16, which is formed integrally with a ceiling wall 17 of the secondary channel 13. Furthermore, the main channel 11 comprises a bottom wall 18, which is likewise formed integrally with a bottom wall 19 of the secondary channel 13.

Die Bodenwand 18 ersteckt sich unterhalb dem Lüfterrad 12 und oberhalb und beabstandet zur Deckenwand 14 der Muffel 3.The bottom wall 18 extends below the fan wheel 12 and above and spaced from the top wall 14 of the muffle third

Darüber hinaus ist zu erkennen, dass die Deckenwand 17 des Nebenkanals 13 im Wesentlichen auf gleichem vertikalen Höhenniveau wie die Bodenwand 18 im Bereich des Hauptkanals 11 liegt. Der Nebenkanal 13 ist somit in vertikaler Richtung betrachtet unterhalb dem Höhenniveau des Hauptkanals 11 angeordnet und erstreckt sich jedoch in eine andere Richtung. Der Nebenkanal 13 umfasst in der Deckenwand 17 eine nach unten geneigte Ablenkplatte 20, welche einstückig mit der Deckenwand 17 ausgebildet ist und eine Prägung in der Deckenwand 17 darstellt.In addition, it can be seen that the ceiling wall 17 of the secondary channel 13 is substantially at the same vertical height level as the bottom wall 18 in the region of the main channel 11. The sub-channel 13 is thus arranged below the height level of the main channel 11 as viewed in the vertical direction and, however, extends in a different direction. The auxiliary channel 13 comprises in the ceiling wall 17 a downwardly inclined baffle plate 20, which is formed integrally with the ceiling wall 17 and constitutes an embossing in the ceiling wall 17.

Die Ablenkplatte 20 ist so orientiert, dass die von dem Gebläse in den Nebenkanal 13 geförderte Luft 21 direkt zur Lampe 15 und auf diese gerichtet ausströmt. Der Nebenkanal 13 ist an seinem Austritt durch einen vorderen Rand 22 begrenzt, wobei gegenüber diesem vorderen Rand 22 die Ablenkplatte 20 dachartig nach vorne überstehend ausgebildet ist. Die zielgerichtete Strömungsführung zur Lampe 15 kann dadurch nochmals verbessert werden.The baffle plate 20 is oriented so that the air 21 conveyed by the fan into the secondary passage 13 flows directly to and directed towards the lamp 15. The side channel 13 is bounded at its exit by a front edge 22, with respect to this front edge 22, the baffle plate 20 is roof-like forward projecting. The targeted flow guidance to the lamp 15 can thereby be further improved.

Wie in Fig. 1 zu erkennen ist, ist der Nebenkanal 13 vom Gebläse 10 in Richtung der Lampe 15 hin verjüngt ausgebildet.As in Fig. 1 can be seen, the secondary channel 13 is formed by the fan 10 in the direction of the lamp 15 tapers.
