In particular, the cooking device can represent an electric cooking device. The cooking device can be an oven, a steam cooker or steam cooking device, a microwave device or a combination thereof.

Die WƤnde, die den Garraum begrenzen, sind insbesondere SeitenwƤnde, RĆ¼ckwand, Decke und Boden des GarraumgehƤuses. Nach vorne wird der Garraum des GargerƤts von einer TĆ¼re des GargerƤts verschlossen. Der Garraum ist vorzugsweise ein ungeteilter Raum. Durch Installationen fĆ¼r GarguttrƤger, beispielsweise Halter oder Schienen fĆ¼r Backbleche, kann der Garraum in verschiedene Ebenen unterteilt werden, die als Garraumebenen oder Garebenen bezeichnet werden.The walls that delimit the cooking space are, in particular, side walls, rear wall, ceiling and floor of the cooking space housing. The cooking space of the cooking device is closed to the front by a door of the cooking device. The cooking space is preferably an undivided space. Through installations for food carriers, for example holders or rails for baking trays, the cooking space can be divided into different levels, which are referred to as cooking space levels or cooking levels.

Als Lichtquelle wird eine Vorrichtung bezeichnet, an der Licht erzeugt wird. Dies kann beispielsweise eine GlĆ¼hlampe, eine Halogenlampe oder eine Leuchtdiode (LED) sein.A device on which light is generated is referred to as a light source. This can be, for example, an incandescent lamp, a halogen lamp or a light-emitting diode (LED).

Als BeleuchtungsgehƤuse wird erfindungsgemƤƟ ein Bauteil bezeichnet, durch das ein Beleuchtungsraum teilweise begrenzt ist, von dem aus Licht in den Garraum abgegeben werden kann. In dem Beleuchtungsraum kann Licht von der Lichtquelle geleitet und/oder reflektiert werden. Als Vorderseite des BeleuchtungsgehƤuses wird die Seite des BeleuchtungsgehƤuses bezeichnet, die im montierten Zustand der Beleuchtungsvorrichtung in dem GargerƤt dem Garraum zugewandt ist und an diesen angrenzt. Als RĆ¼ckseite des BeleuchtungsgehƤuses wird die Seite des BeleuchtungsgehƤuses bezeichnet, die im montierten Zustand der Beleuchtungsvorrichtung der GarraumgehƤusewand zugewandt ist und vorzugsweise an dieser anliegt. Besonders bevorzugt ist das BeleuchtungsgehƤuse in einer Vertiefung in der GarraumgehƤusewand eingebracht. Als Innenseite des BeleuchtungsgehƤuses wird die Seite des Materials des BeleuchtungsgehƤuses bezeichnet, die dem Beleuchtungsraum zugewandt ist.According to the invention, a component is referred to as a lighting housing by which a lighting space is partially delimited, from which light can be emitted into the cooking space. In the lighting space, light can be guided and / or reflected from the light source. The front side of the lighting housing is referred to as the side of the lighting housing which, in the mounted state of the lighting device in the cooking appliance, faces the cooking space and adjoins it. The back of the lighting housing is the side of the lighting housing which, in the mounted state of the lighting device, faces the cooking chamber housing wall and preferably rests against it. The lighting housing is particularly preferably introduced into a recess in the cooking chamber housing wall. The side of the material of the lighting housing that faces the lighting space is referred to as the inside of the lighting housing.

Die Abdeckung der Beleuchtungsvorrichtung ist eine lichtdurchlƤssige Abdeckung. Insbesondere kann die Abdeckung eine Scheibe, beispielsweise Glasscheibe oder Kunststoffscheibe sein. Die Abdeckung stellt vorzugsweise eine ebene Scheibe dar die an dem Rand oder an den RƤndern eine Abstufung aufweisen kann.The cover of the lighting device is a transparent cover. In particular, the cover can be a pane, for example a glass pane or a plastic pane. The cover is preferably a flat disk which can have a step at the edge or at the edges.

ErfindungsgemƤƟ ist an der Vorderseite des BeleuchtungsgehƤuses eine Aufnahmevorrichtung zur Aufnahme zumindest eines Teils der Abdeckung gebildet. Als Aufnahmevorrichtung wird hierbei eine Vorrichtung bezeichnet, in der zumindest ein Teil der Abdeckung aufgenommen und durch die die Abdeckung an dem BeleuchtungsgehƤuse gehalten wird. Die Aufnahmevorrichtung kann an dem BeleuchtungsgehƤuse befestigt sein. Vorzugsweise ist die Aufnahmevorrichtung aber durch einen Teil des BeleuchtungsgehƤuses gebildet, das heiƟt einteilig mit diesem gebildet.According to the invention, a receiving device for receiving at least part of the cover is formed on the front of the lighting housing. A device is referred to here as a receiving device in which at least a part of the cover is received and by which the cover is held on the lighting housing. The receiving device can on the Be attached to the lighting housing. However, the receiving device is preferably formed by a part of the lighting housing, that is to say formed in one piece with it.

ErfindungsgemƤƟ ist die Lichtquelle auƟerhalb des durch das BeleuchtungsgehƤuse und die Abdeckung gebildeten Beleuchtungsmoduls angeordnet. In dem Beleuchtungsmodul ist der Beleuchtungsraum gebildet. Das Beleuchtungsmodul ist mit der Lichtquelle so verbunden, dass Licht von der Lichtquelle in den in dem Beleuchtungsmodul gebildeten Beleuchtungsraum strahlen oder vorzugsweise in diesen geleitet werden kann.According to the invention, the light source is arranged outside the lighting module formed by the lighting housing and the cover. The lighting space is formed in the lighting module. The lighting module is connected to the light source in such a way that light from the light source can radiate into the lighting space formed in the lighting module or, preferably, can be guided into it.

Indem die Lichtquelle auƟerhalb des Beleuchtungsmoduls angeordnet ist, kƶnnen das BeleuchtungsgehƤuse und die Abdeckung der Beleuchtungsvorrichtung einfach ausgestattet sein, da die Lichtquelle durch diese nicht geschĆ¼tzt zu werden braucht. Indem bei der erfindungsgemƤƟ verwendeten Beleuchtungsvorrichtung zudem die Abdeckung unmittelbar an dem BeleuchtungsgehƤuse mittels einer Aufnahmevorrichtung gehalten wird, ist die Teileanzahl reduziert und der Herstellungs- und Montageaufwand verringert. Zudem kann das Beleuchtungsmodul vormontiert werden und als Baueinheit in den Garraum des GargerƤtes, insbesondere in eine Vertiefung in einer der WƤnde des GarraumgehƤuses, eingebracht werden. Hierdurch wird die Montage und Wartung vereinfacht.By arranging the light source outside of the lighting module, the lighting housing and the cover of the lighting device can be simply equipped, since the light source does not need to be protected by them. Since, in the lighting device used according to the invention, the cover is also held directly on the lighting housing by means of a receiving device, the number of parts is reduced and the manufacturing and assembly costs are reduced. In addition, the lighting module can be preassembled and introduced as a structural unit into the cooking space of the cooking appliance, in particular into a recess in one of the walls of the cooking space housing. This simplifies assembly and maintenance.

ErfindungsgemƤƟ ist das BeleuchtungsgehƤuse ein sich lƤngs erstreckendes GehƤuse. Durch eine LƤngsausdehnung des BeleuchtungsgehƤuses kann der Bereich, Ć¼ber den Licht von der Beleuchtungsvorrichtung in den Garraum abgegeben werden kann, maximiert werden. An dem BeleuchtungsgehƤuse ist zumindest eine Durchlassƶffnung fĆ¼r mindestens einen Lichtleiter von der mindestens einen Lichtquelle vorgesehen. Die Durchlassƶffnung oder die Durchlassƶffnungen sind bei dem sich lƤngs erstreckenden BeleuchtungsgehƤuse in mindestens einer der Stirnseiten des BeleuchtungsgehƤuses vorgesehen.According to the invention, the lighting housing is a longitudinally extending housing. By extending the lighting housing longitudinally, the area via which light can be emitted from the lighting device into the cooking space can be maximized. At least one passage opening for at least one light guide from the at least one light source is provided on the lighting housing. In the case of the longitudinally extending lighting housing, the passage opening or openings are provided in at least one of the end faces of the lighting housing.

Als Lichtleiter wird erfindungsgemƤƟ ein Element bezeichnet, das Licht, das in dieses eingekoppelt wird, an einem von dem Einkopplungsort entfernten Ort abgibt, abstrahlt beziehungsweise emittiert. Zu diesem Zweck ist der Lichtleiter aus einem Material hergestellt, das zur Leitung von Licht, insbesondere von Lichtwellen, geeignet ist. Der Lichtleiter kann beispielsweise ein Glaselement oder Kunststoffelement, insbesondere Glasfaserelement oder Kunststofffaserelement darstellen. Der Lichtleiter oder die Lichtleiter sind zur Lichteinkopplung mit der Lichtquelle verbunden.According to the invention, an element is referred to as a light guide which emits, radiates or emits light that is coupled into it at a location remote from the coupling location. For this purpose, the light guide is made of a material that is suitable for guiding light, in particular light waves. The Light guides can represent, for example, a glass element or a plastic element, in particular a glass fiber element or a plastic fiber element. The light guide or the light guides are connected to the light source for coupling in light.

Vorzugsweise stellt der Lichtleiter ein lƤngliches Element dar. Als lƤngliches Element wird vorzugsweise ein Element bezeichnet, das eine LƤngsabmessung aufweist, die grĆ¶ĆŸer ist als die weiteren Abmessungen, insbesondere Breite und Tiefe, des Elementes. Insbesondere kann der Lichtleiter daher eine Stabform aufweisen. Vorzugsweise ist der Lichtleiter in zumindest einem Teilbereich dessen LƤnge, insbesondere in dem Bereich, in dem dieser in dem Beleuchtungsmodul aufgenommen ist, starr. Die dafĆ¼r erforderliche Festigkeit kann durch das Material des Lichtleiters selber oder durch eine entsprechende StĆ¼tzung geschaffen werden.The light guide preferably represents an elongated element. An elongated element is preferably referred to as an element which has a longitudinal dimension which is greater than the further dimensions, in particular width and depth, of the element. In particular, the light guide can therefore have a rod shape. The light guide is preferably rigid in at least a partial area of its length, in particular in the area in which it is received in the lighting module. The strength required for this can be created by the material of the light guide itself or by a corresponding support.

ErfindungsgemƤƟ kann die Beleuchtungsvorrichtung mindestens einen Lichtleiter umfassen. Es ist aber auch mƶglich, dass die Beleuchtungsvorrichtung mindestens zwei Lichtleiter umfasst. Zur besseren Lesbarkeit wird im Folgenden im Wesentlichen auf einen Lichtleiter Bezug genommen. Die AusfĆ¼hrungen zu dem einen Lichtleiter gelten aber - soweit anwendbar - ebenfalls fĆ¼r mehrere Lichtleiter.According to the invention, the lighting device can comprise at least one light guide. However, it is also possible that the lighting device comprises at least two light guides. For better readability, reference is essentially made below to a light guide. However, the statements on the one light guide also apply - if applicable - to several light guides.

Durch das Vorsehen eines Lichtleiters kann Licht von der Lichtquelle, die auƟerhalb des Beleuchtungsmoduls angeordnet ist, zuverlƤssig in den in dem Beleuchtungsmodul gebildeten Beleuchtungsraum und dort an vorgegebene Positionen geleitet werden. Indem die Durchlassƶffnung oder Durchlassƶffnungen in mindestens einer der Stirnseiten des BeleuchtungsgehƤuses vorgesehen sind, kann ein Lichtleiter sich Ć¼ber die gesamte LƤnge des BeleuchtungsgehƤuses erstrecken und somit Ć¼ber die LƤnge des Lichtleiters, die in dem Beleuchtungsmodul aufgenommen ist, Licht abgegeben werden und dadurch kann die Abgabe von Licht in den Garraum maximiert werden. Ein weiterer Vorteil, der in der Anordnung der Durchlassƶffnung oder Durchlassƶffnungen in der oder den Stirnseiten begrĆ¼ndet ist, ist, dass die Durchlassƶffnungen nicht separat in das BeleuchtungsgehƤuse eingebracht werden mĆ¼ssen sondern durch die Form des BeleuchtungsgehƤuses selber gebildet werden kƶnnen. So kann insbesondere ein in Wannen- oder Rinnenform gebogenes Blech als BeleuchtungsgehƤuse dienen, wobei an den Stirnseiten kein Material vorliegt, so dass die gesamten Stirnseiten Durchlassƶffnungen fĆ¼r einen oder mehrere Lichtleiter bilden.By providing a light guide, light from the light source, which is arranged outside the lighting module, can be reliably guided into the lighting space formed in the lighting module and there to predetermined positions. Since the passage opening or passage openings are provided in at least one of the end faces of the lighting housing, a light guide can extend over the entire length of the lighting housing and thus light can be emitted over the length of the light guide, which is received in the lighting module Light in the cooking space can be maximized. Another advantage, which is based on the arrangement of the passage opening or passage openings in the end face (s), is that the passage openings do not have to be introduced separately into the lighting housing but can be formed by the shape of the lighting housing itself. In particular, a sheet metal bent into the shape of a trough or channel can serve as a lighting housing, with no material being present on the end faces, so that the entire end faces form passage openings for one or more light guides.

GemƤƟ einer bevorzugten AusfĆ¼hrungsform ist an der RĆ¼ckseite des BeleuchtungsgehƤuses mindestens eine Befestigungsvorrichtung, insbesondere mindestens ein Gewindebolzen, zur Befestigung an einer GarraumgehƤusewand vorgesehen ist. Unter Befestigung an einer GarraumgehƤusewand wird erfindungsgemƤƟ auch eine Befestigung in einer Vertiefung einer GarraumgehƤusewand verstanden.According to a preferred embodiment, at least one fastening device, in particular at least one threaded bolt, is provided on the rear of the lighting housing for fastening to a cooking chamber housing wall. According to the invention, fastening to a cooking chamber housing wall is also understood to mean fastening in a recess in a cooking chamber housing wall.

Indem die Befestigungsvorrichtung an dem BeleuchtungsgehƤuse vorgesehen ist, ist eine besondere Ausgestaltung des GarraumgehƤuses zur Befestigung des BeleuchtungsgehƤuses nicht erforderlich. Es kann daher ausreichend sein, in dem GarraumgehƤuse und insbesondere in einer Vertiefung in einer der WƤnde des GarraumgehƤuses einen Schraubdurchlass in Form einer Bohrung oder eines Lochs vorzusehen, durch den die Befestigungsvorrichtung, insbesondere der Gewindebolzen durchgreifen kann. Ein Ausbilden komplexer Befestigungsmechanismen an der Wand des GarraumgehƤuses, beispielsweise das Ausstanzen und/oder Auskragen von Rastnasen ist daher nicht erforderlich. Die Befestigungsvorrichtung, insbesondere der Gewindebolzen, ist vorzugsweise starr mit der RĆ¼ckseite des BeleuchtungsgehƤuses verbunden. Beispielsweise kann die Befestigungsvorrichtung an dem BeleuchtungsgehƤuse angeschweiƟt, gelƶtet oder durch eine Schraubverbindung an dem BeleuchtungsgehƤuse befestigt sein. Indem die Befestigungsvorrichtung an der RĆ¼ckseite und vorzugsweise an dem Ende des BeleuchtungsgehƤuses, das den grĆ¶ĆŸten Abstand zu der Vorderseite des BeleuchtungsgehƤuses aufweist, vorgesehen ist, ist ein Einbringen des BeleuchtungsgehƤuses von dem Garraum aus mƶglich. Hierbei wird das aus dem BeleuchtungsgehƤuse und der Abdeckung bestehende Beleuchtungsmodul an die GarraumgehƤusewand angelegt oder vorzugsweise in eine Vertiefung der GarraumgehƤusewand eingebracht und dabei die Befestigungsvorrichtung an dem BeleuchtungsgehƤuse mit einer entsprechenden Ɩffnung an der GarraumgehƤusewand in Eingriff gebracht. AnschlieƟend kann das BeleuchtungsgehƤuse durch Festschrauben einer Mutter oder dergleichen von der AuƟenseite her fixiert werden.Since the fastening device is provided on the lighting housing, a special design of the cooking chamber housing for fastening the lighting housing is not required. It may therefore be sufficient to provide a screw passage in the form of a bore or a hole in the cooking chamber housing and in particular in a recess in one of the walls of the cooking chamber housing, through which the fastening device, in particular the threaded bolt, can reach. It is therefore not necessary to form complex fastening mechanisms on the wall of the cooking chamber housing, for example punching out and / or protruding latching lugs. The fastening device, in particular the threaded bolt, is preferably rigidly connected to the rear of the lighting housing. For example, the fastening device can be welded to the lighting housing, soldered or fastened to the lighting housing by a screw connection. Since the fastening device is provided on the rear side and preferably on the end of the lighting housing which has the greatest distance from the front side of the lighting housing, the lighting housing can be introduced from the cooking space. Here, the lighting module consisting of the lighting housing and the cover is placed on the cooking chamber housing wall or preferably introduced into a recess in the cooking chamber housing wall and the fastening device on the lighting housing is brought into engagement with a corresponding opening on the cooking chamber housing wall. The lighting housing can then be fixed from the outside by screwing in a nut or the like.

Alternativ ist es aber auch mƶglich, dass die Befestigungsvorrichtung beispielsweise einen Gewindebolzen mit Innengewinde darstellt. In diesem Fall kann vor dem Einsetzen der Abdeckung in das BeleuchtungsgehƤuse eine Schraube durch den Gewindebolzen gefĆ¼hrt beziehungsweise geschraubt werden und an dem Ende, das auƟerhalb des Garraums ist, kann die Schraube beispielsweise mit einem dort vorgesehenen Schraubdom eingreifen.Alternatively, however, it is also possible that the fastening device represents, for example, a threaded bolt with an internal thread. In this case, before inserting the cover into the lighting housing, a screw can be passed or screwed through the threaded bolt and at the end that is outside the Is the cooking space, the screw can, for example, engage with a screw dome provided there.

ErfindungsgemƤƟ besteht das BeleuchtungsgehƤuse aus einem Blech. Dies ist von Vorteil, da ein Blech auf einfache Weise in die erforderliche Form gebracht werden kann. Vorzugsweise stellt insbesondere bei einem aus Blech bestehenden BeleuchtungsgehƤuse die Aufnahmevorrichtung eine Klemmverbindung zwischen dem vorgespannten Blech und zumindest einem Teil des Randes der Abdeckung dar. Hierbei ist das Blech in einer Wannen- oder Rinnenform gebogen und dass Blech ist vorzugsweise so vorgespannt, dass die freien Enden der Rinne zueinander drƤngen. Zwischen diesen freien Enden kann dann die Abdeckung aufgenommen und durch die Klemmkraft gehalten werden. Vorzugsweise weist aber auch bei dieser AusfĆ¼hrungsform das BeleuchtungsgehƤuse im Bereich des vorderen Endes eine Stufe auf, an der die RĆ¼ckseite der Abdeckung beim Einbringen angelegt werden kann. Hierdurch kann ein Verrutschen der Abdeckung in das BeleuchtungsgehƤuse vermieden werden. ZusƤtzlich oder alternativ zu einer Abstufung kann an den freien RƤndern des BeleuchtungsgehƤuses eine Abkantung vorgesehen sein, die die Abdeckung am Rand umgreift und dadurch ein Lƶsen der Abdeckung aus der Klemmverbindung mit dem BeleuchtungsgehƤuse verhindert.According to the invention, the lighting housing consists of a sheet metal. This is advantageous because a sheet can be brought into the required shape in a simple manner. In the case of a lighting housing made of sheet metal, the receiving device preferably represents a clamping connection between the prestressed sheet metal and at least part of the edge of the cover. Here, the sheet metal is bent in a trough or channel shape and the sheet metal is preferably prestressed so that the free ends of the gutter towards each other. The cover can then be received between these free ends and held by the clamping force. In this embodiment too, however, the lighting housing preferably has a step in the region of the front end, against which the rear side of the cover can be placed when it is inserted. This can prevent the cover from slipping into the lighting housing. In addition or as an alternative to a step, a fold can be provided on the free edges of the lighting housing, which surrounds the cover at the edge and thereby prevents the cover from being released from the clamping connection with the lighting housing.

GemƤƟ einer weiteren AusfĆ¼hrungsform stellt die Aufnahmevorrichtung zumindest eine Abkantung zum Umgreifen zumindest eines Teils des Randes der Abdeckung dar. Als Abkantung wird hierbei sowohl eine Abkantung am Rand des BeleuchtungsgehƤuses als auch eine aus der FlƤche des BeleuchtungsgehƤuses ausgestanzte und gebogene Abkantung verstanden. Eine Abkantung oder Abkantungen, die durch Biegen des Randes des BeleuchtungsgehƤuses erzeugt sind, umgreifen nach dem Einbringen zumindest einen Teil des Randes der Abdeckung. Bei einem rinnenfƶrmigen BeleuchtungsgehƤuse umgreifen die Abkantungen dabei zumindest einen Teil der LƤngsrƤnder der Abdeckung.According to a further embodiment, the receiving device represents at least one bevel for gripping around at least part of the edge of the cover. Here, a bevel is understood to mean both a bevel on the edge of the lighting housing and a bevel punched and bent from the surface of the lighting housing. A fold or folds, which are produced by bending the edge of the lighting housing, encompass at least part of the edge of the cover after it has been introduced. In the case of a channel-shaped lighting housing, the folds encompass at least part of the longitudinal edges of the cover.

GemƤƟ einer bevorzugten AusfĆ¼hrungsform wirkt die Aufnahmevorrichtung sowohl auf die Vorderseite als auch auf die RĆ¼ckseite der Abdeckung ein. Dies kann beispielsweise durch Vorsehen einer Abkantung an dem vorderen Rand des BeleuchtungsgehƤuses und ein zusƤtzliches Vorsehen eines Absatzes oder einer weiteren Abkantung in einem Abstand zu dem vorderen Rand des BeleuchtungsgehƤuses umgesetzt werden.According to a preferred embodiment, the receiving device acts both on the front side and on the rear side of the cover. This can be implemented, for example, by providing a fold on the front edge of the lighting housing and an additional provision of a shoulder or a further fold at a distance from the front edge of the lighting housing.

Hierdurch wird die Abdeckung sowohl an einer seitlichen Bewegung in dem BeleuchtungsgehƤuse als auch an einer Bewegung in Richtung in das Innere des BeleuchtungsgehƤuses gehindert.This prevents the cover from moving laterally in the lighting housing as well as from moving in the direction of the interior of the lighting housing.

Die Innenseite des BeleuchtungsgehƤuses kann zumindest teilweise eine reflektierende Beschichtung aufweisen. Hierdurch kann die Ausleuchtung des Garraumes weiter verbessert werden. Indem die Beschichtung unmittelbar an dem BeleuchtungsgehƤuse vorgesehen ist, ist kein separater Reflektor notwendig und der Aufbau des BeleuchtungsgehƤuse und der Beleuchtungsvorrichtung ist damit einfach. Die reflektierende Beschichtung kann beispielsweise eine metallisch glƤnzende Beschichtung oder vorzugsweise eine weiƟe Schicht sein. Die Schicht kann beispielsweise durch Plasmabeschichten oder Emaillieren erzeugt werden.The inside of the lighting housing can at least partially have a reflective coating. In this way, the illumination of the cooking space can be further improved. Since the coating is provided directly on the lighting housing, no separate reflector is necessary and the construction of the lighting housing and the lighting device is therefore simple. The reflective coating can be, for example, a metallic glossy coating or, preferably, a white layer. The layer can be produced, for example, by plasma coating or enameling.

Zwischen dem BeleuchtungsgehƤuse und der Abdeckung kann eine oder kƶnnen mehrere Dichtungen eingebracht sein.One or more seals can be introduced between the lighting housing and the cover.

Vorteile und Merkmale, die bezĆ¼glich der Beleuchtungsvorrichtung beschrieben wurden und werden, gelten - soweit anwendbar - fĆ¼r das erfindungsgemƤƟe GargerƤt entsprechend und umgekehrt.Advantages and features that have been and will be described with respect to the lighting device apply - insofar as they are applicable - to the cooking device according to the invention and vice versa.

Die Beleuchtungsvorrichtung ist erfindungsgemƤƟ zumindest teilweise in dem Garraum vorgesehen. Hierbei sind insbesondere das Beleuchtungsmodul bestehend aus BeleuchtungsgehƤuse und Abdeckung in dem Garraum vorgesehen, wobei vorzugsweise zumindest das BeleuchtungsgehƤuse in einer Vertiefung einer Garraumwand aufgenommen ist. Weiterhin kann zumindest der Teil des Lichtleiters, der in dem Beleuchtungsraum des Beleuchtungsmoduls gefĆ¼hrt ist, als in dem Garraum befindlich bezeichnet werden. Die Lichtquelle hingegen ist bei dem erfindungsgemƤƟen GargerƤt nicht in dem Garraum vorgesehen. Die Lichtquelle kann beispielsweise in dem Zwischenraum zwischen GarraumgehƤuse und GargerƤtegehƤuse angeordnet sein.According to the invention, the lighting device is at least partially provided in the cooking space. In particular, the lighting module consisting of the lighting housing and cover is provided in the cooking space, with at least the lighting housing preferably being received in a recess in a cooking space wall. Furthermore, at least that part of the light guide that is guided in the lighting space of the lighting module can be referred to as being located in the cooking space. In contrast, the light source is not provided in the cooking space in the cooking device according to the invention. The light source can be arranged, for example, in the space between the cooking chamber housing and the cooking appliance housing.

Das BeleuchtungsgehƤuse ist vorzugsweise zumindest teilweise in einer Vertiefung einer der GarraumgehƤusewƤnde aufgenommen. Besonders bevorzugt entspricht die Tiefe der Vertiefung der Tiefe des BeleuchtungsgehƤuses, so dass die Vorderseite des BeleuchtungsgehƤuses mit der GarraumgehƤusewand, in der die Vertiefung vorgesehen ist, bĆ¼ndig ist. Hierdurch wird insbesondere die Reinigung des Inneren des Garraums vereinfacht. Es liegt aber auch im Rahmen der Erfindung, dass die Vorderseite des BeleuchtungsgehƤuses um einen gewissen Betrag Ć¼ber die GarraumgehƤusewand, in der die Vertiefung vorgesehen ist, hervorsteht.The lighting housing is preferably at least partially received in a recess in one of the cooking chamber housing walls. Particularly preferably, the depth of the recess corresponds to the depth of the lighting housing, so that the front side of the lighting housing with the cooking chamber housing wall in which the recess is provided is, is flush. This in particular simplifies the cleaning of the interior of the cooking space. However, it is also within the scope of the invention that the front of the lighting housing protrudes by a certain amount over the cooking chamber housing wall in which the recess is provided.

Das Beleuchtungsmodul weist Abmessungen auf, die denen einer Vertiefung in der GarraumgehƤusewand entsprechen. Das bedeutet, dass vorzugsweise eine solche Vertiefung durch ein darin aufgenommenes Beleuchtungsmodul vollstƤndig ausgefĆ¼llt ist.The lighting module has dimensions that correspond to those of a recess in the cooking chamber housing wall. This means that such a depression is preferably completely filled by a lighting module accommodated therein.

GemƤƟ der vorliegenden Erfindung kann das BeleuchtungsgehƤuse in mindestens einer GarraumgehƤusewand vertikal oder horizontal angeordnet sein. In der entsprechenden Ausrichtung ist dann vorteilhaft eine entsprechende Vertiefung in der GarraumgehƤusewand vorgesehen. Vorzugsweise entspricht die LƤnge des BeleuchtungsgehƤuses der Hƶhe oder LƤnge der GarraumgehƤusewand, in der dieses in einer Vertiefung eingebracht ist. Die LƤnge des BeleuchtungsgehƤuses ist dabei geringfĆ¼gig kĆ¼rzer als die LƤnge oder Breite der GarraumgehƤusewand. Dennoch wird der Garraum in diesem Bereich Ć¼ber die gesamte Ausdehnung der entsprechenden GarraumgehƤusewand ausgeleuchtet.According to the present invention, the lighting housing can be arranged vertically or horizontally in at least one cooking chamber housing wall. In the corresponding alignment, a corresponding depression is then advantageously provided in the cooking chamber housing wall. The length of the lighting housing preferably corresponds to the height or length of the cooking chamber housing wall in which it is placed in a recess. The length of the lighting housing is slightly shorter than the length or width of the cooking chamber housing wall. Nevertheless, the cooking space is illuminated in this area over the entire extent of the corresponding cooking space housing wall.

ErfindungsgemƤƟ weist das erfindungsgemƤƟe GargerƤt mindestens eine erfindungsgemƤƟe Beleuchtungsvorrichtung auf. Besonders bevorzugt ist an zwei gegenĆ¼berliegenden SeitenflƤchen des Garraums jeweils mindestens ein Beleuchtungsmodul gemƤƟ der vorliegenden Erfindung vorgesehen.According to the invention, the cooking appliance according to the invention has at least one lighting device according to the invention. At least one lighting module according to the present invention is particularly preferably provided on two opposite side surfaces of the cooking space.

Das GargerƤt kann einen Backofen, ein MikrowellengerƤt oder eine Kombination, insbesondere einen Mikrowellenofen darstellen.
Die Erfindung wird im Folgenden erneut unter Bezugnahme auf die beiliegenden Zeichnungen erlƤutert. Es zeigen:

  • Figur 1: eine schematische perspektivische Frontansicht einer AusfĆ¼hrungsform des erfindungsgemƤƟen GargerƤtes im Bereich des GarraumgehƤuses ;

  • Figur 3: eine schematische Schnittdarstellung durch eine weitere AusfĆ¼hrungsform eines Teils der erfindungsgemƤƟ verwendeten Beleuchtungsvorrichtung.
The cooking device can be an oven, a microwave device or a combination, in particular a microwave oven.
The invention is explained again below with reference to the accompanying drawings. Show it:
  • Figure 1 : a schematic perspective front view of an embodiment of the cooking device according to the invention in the area of the cooking space housing;
  • Figure 2 : a schematic sectional illustration through an embodiment of a part of the lighting device used according to the invention; and
  • Figure 3 : a schematic sectional illustration through a further embodiment of part of the lighting device used according to the invention.

In Figur 1 ist eine perspektivische Frontansicht eines Teils einer AusfĆ¼hrungsform des erfindungsgemƤƟen GargerƤtes 1 gezeigt. Das GargerƤtegehƤuse, das das dargestellte GarraumgehƤuse 2 umgibt, ist in der Figur 1 nicht dargestellt. Oberhalb des GarraumgehƤuses 2 ist eine Bedienleiste 8 des GargerƤtes angedeutet, Ć¼ber die das GargerƤt 1, sowie die in dem GargerƤt 1 vorgesehene Beleuchtungsvorrichtung 10 bedient werden kann. Von der Beleuchtungsvorrichtung 10 ist in der Figur 1 nur die Abdeckung 12 und das vordere Ende des BeleuchtungsgehƤuses 11 zu sehen. Der genauere Aufbau der Beleuchtungsvorrichtung 10 wird spƤter unter Bezugnahme auf die Figuren 2 und 3 genauer erlƤutert.In Figure 1 a perspective front view of part of an embodiment of the cooking device 1 according to the invention is shown. The cooking appliance housing that surrounds the illustrated cooking chamber housing 2 is in the Figure 1 not shown. A control bar 8 of the cooking device is indicated above the cooking space housing 2, via which the cooking device 1 and the lighting device 10 provided in the cooking device 1 can be operated. Of the lighting device 10 is in the Figure 1 only the cover 12 and the front end of the lighting housing 11 can be seen. The more detailed structure of the lighting device 10 will be described later with reference to FIG Figures 2 and 3 explained in more detail.

Das Beleuchtungsmodul 100 der Beleuchtungsvorrichtung 1, das zumindest aus dem BeleuchtungsgehƤuse 11 und der Abdeckung 12 besteht, ist in der in Figur 1 gezeigten AusfĆ¼hrungsform in der Vertikalen der Seitenwand 5 des GarraumgehƤuses 2 eingebracht. In der gegenĆ¼ber liegenden Seitenwand 4 ist ebenfalls ein Beleuchtungsmodul 100 (in Figur 1 nicht sichtbar) eingebracht. Das Beleuchtungsmodul 100 ist in eine Vertiefung 7 in der jeweiligen GarraumgehƤusewand 4, 5 aufgenommen. Die LƤnge und Breite des Beleuchtungsmoduls 100 entsprechen hierbei jeweils der LƤnge und der Breite der Vertiefung 7, so dass die Vertiefung 7 vollstƤndig ausgefĆ¼llt ist. Wie an der Vertiefung 7 in der linken Seitenwand 4 zu erkennen ist, sind in den Stirnseiten der Vertiefung 7 LichtleiterdurchlƤsse 71 vorgesehen. In der dargestellten AusfĆ¼hrungsform sind in jeder Stirnseite jeder Vertiefung 7 drei LichtleiterdurchlƤsse 71 eingebracht. Nachdem das Beleuchtungsmodul 100, wie in Figur 1 gezeigt, in die Vertiefung 7 eingebracht ist, kƶnnen durch diese LichtleiterdurchlƤsse Lichtleiter 13 gefĆ¼hrt werden. Diese weisen vorzugsweise eine LƤnge auf, die zumindest der LƤnge der Vertiefung 7 entspricht oder vorzugsweise grĆ¶ĆŸer als die LƤnge der Vertiefung 7 ist. Eines der Enden jedes der Lichtleiter 13 wird mit einer Lichtquelle (nicht gezeigt) direkt oder Ć¼ber weitere Komponenten verbunden.The lighting module 100 of the lighting device 1, which consists at least of the lighting housing 11 and the cover 12, is shown in FIG Figure 1 The embodiment shown introduced in the vertical of the side wall 5 of the cooking chamber housing 2. A lighting module 100 (in Figure 1 not visible). The lighting module 100 is received in a recess 7 in the respective cooking chamber housing wall 4, 5. The length and width of the lighting module 100 correspond in each case to the length and the width of the recess 7, so that the recess 7 is completely filled. As can be seen from the recess 7 in the left side wall 4, light guide openings 71 are provided in the end faces of the recess 7. In the embodiment shown, three light guide openings 71 are made in each end face of each depression 7. After the lighting module 100, as in Figure 1 shown, is introduced into the recess 7, light guides 13 can be guided through these light guide passages. These preferably have a length which at least corresponds to the length of the depression 7 or is preferably greater than the length of the depression 7. One of the ends of each of the light guides 13 is connected to a light source (not shown) directly or via further components.

In einer alternativen AusfĆ¼hrungsform kƶnnen mehre Vertiefungen in den SeitenwƤnden 4, 5 vorgesehen sein, und/oder mindestens eine Vertiefung in der Decke 3, dem Boden 6 oder der RĆ¼ckwand (nicht sichtbar) des GarraumgehƤuses 2 vorgesehen sein. Die Vertiefungen kƶnnen auch statt vertikal horizontal ausgerichtet sein.In an alternative embodiment, several depressions can be provided in the side walls 4, 5 and / or at least one depression can be provided in the ceiling 3, the floor 6 or the rear wall (not visible) of the cooking chamber housing 2. The depressions can also be oriented horizontally instead of vertically.

In der Figur 2 ist eine Schnittansicht eines Beleuchtungsmoduls 100 einer AusfĆ¼hrungsform der erfindungsgemƤƟ verwendeten Beleuchtungsvorrichtung 10 gezeigt. Das Beleuchtungsmodul 100 umfasst in der dargestellten AusfĆ¼hrungsform ein BeleuchtungsgehƤuse 11 sowie eine Abdeckung 12. Durch das BeleuchtungsgehƤuse 11 und die Abdeckung 12 wird ein Beleuchtungsraum 16 definiert. Das Beleuchtungsmodul 100 ist in einer Vertiefung 7 einer Wand 3, 4, 5, 6 des GarraumgehƤuses 2 soweit aufgenommen, dass die Vorderseite des Beleuchtungsmoduls 100, die dem Garraum 20 zugewandt ist, mit der Wand 3, 4, 5, 6 des GarraumgehƤuses 2 bĆ¼ndig ist.In the Figure 2 a sectional view of a lighting module 100 of an embodiment of the lighting device 10 used according to the invention is shown. In the embodiment shown, the lighting module 100 comprises a lighting housing 11 and a cover 12. A lighting space 16 is defined by the lighting housing 11 and the cover 12. The lighting module 100 is accommodated in a recess 7 in a wall 3, 4, 5, 6 of the cooking space housing 2 to such an extent that the front side of the lighting module 100, which faces the cooking space 20, with the wall 3, 4, 5, 6 of the cooking space housing 2 is flush.

Das BeleuchtungsgehƤuse 11 ist in der gezeigten AusfĆ¼hrungsform ein rinnenfƶrmiges Blech. An der Vorderseite des BeleuchtungsgehƤuses 11 sind die LƤngsrƤnder des Bleches nach innen gebogen. Die LƤngsrƤnder sind so weit nach innen gebogen, dass diese aufeinander gerichtet sind. Durch dieses Umbiegen der RƤnder des Blechs, aus dem das BeleuchtungsgehƤuses 11 besteht, sind Abkantungen 150, die auch als Klauen bezeichnet werden kƶnnen gebildet. Durch die Abkantungen 150 wird die Abdeckung 12 in dem BeleuchtungsgehƤuse 11 gehalten. Die Abdeckung 12 stellt eine ebene Scheibe dar. Die Abdeckung 12 weist eine LƤnge auf, die der LƤnge des BeleuchtungsgehƤuses 11 entspricht. In der dargestellten AusfĆ¼hrungsform ist die Dicke der Abdeckung an den LƤngsrƤndern geringer als Ć¼ber den Rest der Breite, so dass an den LƤngsrƤndern der Abdeckung 12 Stufen 120 gebildet sind. An diesen Stufen 120 liegen die Abkantungen 150 des BeleuchtungsgehƤuses 11 an. Hierdurch ist zum einen die Vorderseite des Beleuchtungsmoduls 100 eben und zum anderen kann ein seitliches Verrutschen der Abdeckung 12 in dem BeleuchtungsgehƤuse 11 zusƤtzlich verhindert werden.In the embodiment shown, the lighting housing 11 is a trough-shaped sheet metal. At the front of the lighting housing 11, the longitudinal edges of the sheet are bent inward. The longitudinal edges are bent inwards so that they are directed towards one another. This bending over of the edges of the sheet metal from which the lighting housing 11 is made, folds 150, which can also be referred to as claws, are formed. The cover 12 is held in the lighting housing 11 by the bevels 150. The cover 12 is a flat disk. The cover 12 has a length which corresponds to the length of the lighting housing 11. In the embodiment shown, the thickness of the cover at the longitudinal edges is less than over the remainder of the width, so that steps 120 are formed on the longitudinal edges of the cover 12. The bevels 150 of the lighting housing 11 rest on these steps 120. As a result, on the one hand, the front side of the lighting module 100 is flat and, on the other hand, lateral slipping of the cover 12 in the lighting housing 11 can also be prevented.

Die Breite des BeleuchtungsgehƤuses 11 nimmt aufgrund der Rinnenform von der Vorderseite des Beleuchtungsmoduls 100 aus zu der RĆ¼ckseite des Beleuchtungsmoduls 100 ab. Durch diese AusfĆ¼hrungsform wird die RĆ¼ckseite der LƤngsrƤnder der Abdeckung 12 durch die Innenseite des BeleuchtungsgehƤuses 11 gehalten und insbesondere an einem Verrutschen in das Innere des BeleuchtungsgehƤuses 11 gehindert.The width of the lighting housing 11 decreases from the front of the lighting module 100 to the rear of the lighting module 100 due to the channel shape. With this embodiment, the rear side of the longitudinal edges of the cover 12 is held by the inside of the lighting housing 11 and, in particular, is prevented from slipping into the interior of the lighting housing 11.

In dem durch das BeleuchtungsgehƤuse 11 und die Abdeckung umschlossenen Beleuchtungsraum 16 sind Lichtleiter 13 gefĆ¼hrt. In der dargestellten AusfĆ¼hrungsform sind drei Lichtleiter 13 gezeigt. Diese verlaufen in LƤngsrichtung des Beleuchtungsmoduls 100. Die Lichtleiter 13 sind in dem Bereich in dem diese in dem Beleuchtungsmodul 100 verlaufen und Licht abgeben, vorzugsweise starr ausgebildet. Die Lichtleiter 13 werden beispielsweise durch die LichtleiterdurchlƤsse 71 in den Stirnseiten der Vertiefung 71 gehalten, so dass eine zusƤtzliche Halterung in dem Beleuchtungsmodul 100 nicht erforderlich ist.In the lighting space 16 enclosed by the lighting housing 11 and the cover, light guides 13 are guided. In the embodiment shown, three light guides 13 are shown. These run in the longitudinal direction of the lighting module 100. The light guides 13 are preferably rigid in the area in which they run in the lighting module 100 and emit light. The light guides 13 are held, for example, by the light guide openings 71 in the end faces of the recess 71, so that an additional holder in the lighting module 100 is not required.

In Figur 3 ist ein Beleuchtungsmodul 100 einer weiteren AusfĆ¼hrungsform der erfindungsgemƤƟ verwendeten Beleuchtungsvorrichtung 10 gezeigt.In Figure 3 a lighting module 100 of a further embodiment of the lighting device 10 used according to the invention is shown.

Diese AusfĆ¼hrungsform entspricht im Wesentlichen der AusfĆ¼hrungsform aus Figur 2. Die einzigen Unterschiede, die zu dieser AusfĆ¼hrungsform bestehen, sind, dass bei der AusfĆ¼hrungsform nach Figur 3 das Beleuchtungsmodul 100 eine Befestigungsvorrichtung 14 aufweist, in der Vertiefung 7 ein Schraubdurchlass 71 fĆ¼r die Befestigungsvorrichtung 14 vorgesehen ist und dass an dem BeleuchtungsgehƤuse 11 versetzt zu den ƤuƟeren Abkantungen 150 zusƤtzlich innere Abkantungen 151 vorgesehen sind.This embodiment corresponds essentially to the embodiment from FIG Figure 2 . The only differences that exist from this embodiment are that in the embodiment according to FIG Figure 3 the lighting module 100 has a fastening device 14, in the recess 7 a screw passage 71 is provided for the fastening device 14 and that additional inner folds 151 are provided on the lighting housing 11 offset from the outer folds 150.

Die Befestigungsvorrichtung 14 ist in der dargestellten AusfĆ¼hrungsform ein Gewindebolzen, der sich von der RĆ¼ckseite des BeleuchtungsgehƤuses 11 aus senkrecht zu der LƤngsachse und Breite des BeleuchtungsgehƤuses 11 erstreckt. Die Befestigungsvorrichtung 14 ist durch einen Schraubdurchlass 70, der in der Vertiefung 7 eingebracht ist, gefĆ¼hrt und ragt Ć¼ber die RĆ¼ck- oder AuƟenseite der Vertiefung 7 hinaus. Hierdurch kann das Beleuchtungsmodul 100 an der Vertiefung 7 und damit an der GehƤusewand 3, 4, 5 befestigt werden und zudem erfolgt ein Durchkontaktieren.In the embodiment shown, the fastening device 14 is a threaded bolt which extends from the rear side of the lighting housing 11 perpendicular to the longitudinal axis and width of the lighting housing 11. The fastening device 14 is guided through a screw passage 70 which is made in the recess 7 and protrudes beyond the rear or outside of the recess 7. In this way, the lighting module 100 can be fastened to the recess 7 and thus to the housing wall 3, 4, 5 and, in addition, through-hole contacting takes place.

Die inneren Abkantungen 151 sind an dem BeleuchtungsgehƤuse 11 in einem Abstand zum vorderen Ende des BeleuchtungsgehƤuses 11 vorgesehen. Die inneren Abkantungen 151 kƶnnen durch Ausstanzen von Laschen in der FlƤche des BeleuchtungsgehƤuses 11 und Biegen der Laschen nach innen zum Inneren des BeleuchtungsgehƤuses 11 erzeugt werden. Alternativ kƶnnen die inneren Abkantungen 151 aber beispielsweise auch dadurch erzeugt werden, dass in den vorderen Rand des BeleuchtungsgehƤuses 11 Schlitze eingebracht werden und die Bereiche zwischen den Schlitzen zumindest teilweise nach innen gebogen werden. Bei dieser AusfĆ¼hrungsform liegen die inneren Abkantungen 151 und ƤuƟeren Abkantungen 150 Ć¼ber die LƤnge des BeleuchtungsgehƤuses 11 versetzt vor.The inner folds 151 are provided on the lighting housing 11 at a distance from the front end of the lighting housing 11. The inner folds 151 can be produced by punching out tabs in the surface of the lighting housing 11 and bending the tabs inwards towards the interior of the lighting housing 11. Alternatively, however, the inner folds 151 can also be produced, for example, by inserting into the front edge of the Lighting housing 11 slots are introduced and the areas between the slots are at least partially bent inward. In this embodiment, the inner folds 151 and outer folds 150 are offset over the length of the lighting housing 11.

Die vorliegende Erfindung ist nicht auf die dargestellten AusfĆ¼hrungsformen beschrƤnkt. Insbesondere kann die Form des BeleuchtungsgehƤuses von der dargestellten Form abweichen und beispielsweise eine eckige Wannenform aufweisen und/oder mit Stufen im Bereich des vorderen Endes des BeleuchtungsgehƤuses versehen sein, an denen die RĆ¼ckseite der RƤnder der Abdeckung anliegen kƶnnen. Solche Stufen stellen eine alternative AusfĆ¼hrungsform der Abkantungen zu den gezeigten Klauen dar. Weiterhin kƶnnen in dem Beleuchtungsmodul zusƤtzlich zu dem BeleuchtungsgehƤuse und der Abdeckung eine oder mehrere Dichtungen, insbesondere zwischen den Abkantungen und der Abdeckung vorgesehen sein.The present invention is not limited to the illustrated embodiments. In particular, the shape of the lighting housing can differ from the shape shown and, for example, have an angular trough shape and / or be provided with steps in the area of the front end of the lighting housing against which the back of the edges of the cover can rest. Such steps represent an alternative embodiment of the folds to the claws shown. Furthermore, one or more seals, in particular between the folds and the cover, can be provided in the lighting module in addition to the lighting housing and the cover.

Weiterhin ist die Erfindung nicht auf die AusfĆ¼hrungsform beschrƤnkt, bei der das Beleuchtungsmodul zunƤchst in einer Vertiefung der GarraumgehƤusewand eingebracht und gegebenenfalls befestigt wird, bevor die Lichtleiter durch das Beleuchtungsmodul gefĆ¼hrt werden. Es liegt auch im Rahmen der Erfindung die Lichtleiter in dem Beleuchtungsmodul vor dem Einbringen in die Vertiefung vorzusehen und die Lichtleiter anschlieƟend mit der Lichtquelle zu verbinden.Furthermore, the invention is not limited to the embodiment in which the lighting module is first introduced into a recess in the cooking chamber housing wall and, if necessary, fastened before the light guides are guided through the lighting module. It is also within the scope of the invention to provide the light guides in the lighting module before they are introduced into the recess and then to connect the light guides to the light source.

Die vorliegende Erfindung weist eine Reihe von Vorteilen auf. Insbesondere kann das zumindest aus dem BeleuchtungsgehƤuse und der Abdeckung bestehende Beleuchtungsmodul als Paket vom Inneren des Garraums des GargerƤtes aus in eine Vertiefung in einer GarraumgehƤusewand eingeschoben werden. Hierdurch vereinfachen sich die Montage und Wartung des GargerƤtes und insbesondere der Beleuchtungsvorrichtung. Zudem wird durch das erfindungsgemƤƟ verwendete Beleuchtungsmodul ein in dem Beleuchtungsmodul aufgenommener Lichtleiter gegen ƤuƟere EinflĆ¼sse, wie Schmutz, Reinigungsmittel und dergleichen geschĆ¼tzt. Insbesondere bei einem BeleuchtungsgehƤuse, das aus einem Reflektorblech besteht, ist der Aufbau des Beleuchtungsmoduls besonders einfach, da das BeleuchtungsgehƤuse sowohl die Funktion des Reflektors als auch die Funktion der Befestigung der Abdeckung, die insbesondere eine Glasscheibe darstellen kann, Ć¼bernimmt.The present invention has a number of advantages. In particular, the lighting module consisting at least of the lighting housing and the cover can be pushed as a package from the interior of the cooking space of the cooking device into a recess in a cooking space housing wall. This simplifies the assembly and maintenance of the cooking device and in particular of the lighting device. In addition, the lighting module used according to the invention protects a light guide accommodated in the lighting module against external influences such as dirt, cleaning agents and the like. Particularly in the case of a lighting housing that consists of a reflector sheet, the construction of the lighting module is particularly simple, since the lighting housing takes on both the function of the reflector and the function of fastening the cover, which can in particular represent a pane of glass.
