Description

Die Erfindung betrifft eine Beleuchtungseinrichtung für Haushaltsgeräte, in deren Innenraum eine Konsole für die Aufnahme von Tragböden angeordnet ist.The invention relates to a lighting device for household appliances, in the Interior a console is arranged for the inclusion of trays.

Aus dem Stand der Technik ist bekannt, zur Beleuchtung des Innenraums von Kühlschränken an einer Seitenwand des Innenraumes eine Lampe anzubringen. Mittels eines Kontakts wird diese Lampe beim Öffnen der Kühlschranktür eingeschaltet. Die Anordnung der Lampe an einer Seitenwand hat jedoch den Nachteil, dass große Kühlgutbehälter oder Lebensmittelpackungen die Lampe abdecken. Dies führt zu einer deutlichen Reduzierung der Lichtausbeute, da ein großer Teil des Kühlschrankinnenraumes vom Kühlgut abgeschattet ist. Da die bekannten verwendeten Lampen üblicherweise als Glühlampen ausgebildet sind, ist es weiterhin nachteilig, dass die durch die Glühlampen erzeugte Wärme den Kühlraum unnötig erwärmt. It is known from the prior art for illuminating the interior of Refrigerators to attach a lamp to a side wall of the interior. This lamp is switched on by means of a contact when the refrigerator door is opened. However, the arrangement of the lamp on a side wall has the disadvantage that that large refrigerated goods containers or food packages cover the lamp. This leads to a significant reduction in the luminous efficacy, since a large part of the refrigerator interior is shadowed by the refrigerated goods. Because the well-known lamps used are usually designed as incandescent lamps, it is still disadvantageous that the heat generated by the incandescent lamps the refrigerator compartment heated unnecessarily.

Aus der bisher noch nicht veröffentlichten deutschen Patentanmeldung mit dem Aktenzeichen DE 102 16 769.9 ist eine Konsole für Tragböden in Haushaltsgeräten bekannt, welche eine Profilschiene aufweist, die im wesentlichen vertikal verlaufend in dem Innenraum eines Kühlschranks montiert ist. Zusätzlich weist die Konsole ein Trägerelement auf, an dem ein Tragboden angebracht ist und das wahlweise entlang der Profilschiene verschiebbar oder an der Profilschiene festlegbar ist. Das Trägerelement lässt sich gegen eine Bewegung entlang der Profilschiene an der Profilschiene festlegen. Eine derartige Konsole für Tragböden in Haushaltsgeräten gestattet eine flexible Einstellung der Höhe der Tragböden. Allerdings können auch durch eine derartige Konsolenanordnung die Nachteile einer an einer Seitenwand angebrachten Lampe nicht ohne weiteres beseitigt werden.From the as yet unpublished German patent application with the File number DE 102 16 769.9 is a console for trays in household appliances known which has a profile rail which is substantially vertical is mounted in the interior of a refrigerator. Additionally points the console has a support element on which a supporting floor is attached and that can be moved either along the profile rail or on the profile rail is definable. The carrier element can be prevented from moving along the Fix the profile rail on the profile rail. Such a console for trays in household appliances allows flexible adjustment of the height of the trays. However, such a console arrangement can also Disadvantages of a lamp attached to a side wall are not easy be eliminated.

Es ist daher Aufgabe der Erfindung, eine Beleuchtungsanordnung für Haushaltsgeräte anzugeben, welche es ermöglicht, den Innenraum eines derartigen Haushaltsgerätes möglichst gleichmäßig auszuleuchten und den Wärmeeintrag gegenüber üblichen Glühlampen stark zu reduzieren.It is therefore an object of the invention to provide a lighting arrangement for household appliances specify which makes it possible to use the interior of such a household appliance Illuminate as evenly as possible and compare the heat input greatly reduce the incandescent lamps.

Diese Aufgabe der Erfindung wird durch die Merkmale des Anspruches 1 gelöst. Vorteilhafte Weiterbildungen sind in den Unteransprüchen beschrieben.This object of the invention is achieved by the features of claim 1. Advantageous further developments are described in the subclaims.

Demgemäss umfasst die Beleuchtungseinrichtung Leuchtmittel, welche an mindestens einem Teilbereich der Konsole oder in diesem integriert ausgebildet sind. Mit einer derartigen Anordnung wird vermieden, dass nur von einem im wesentlichen punktförmigen Ort im Innenraum des Haushaltsgeräts dessen Innenraum ausgeleuchtet wird. Vielmehr erfolgt mit der erfindungsgemäßen Beleuchtungseinrichtung eine Ausleuchtung des Innraums von mindestens einem Teilbereich der Konsole aus. Zudem wird der Wärmeeintrag in den Innenraum dadurch verringert, dass die Leuchtmittel an der Konsole bzw. in dieser integriert ausgebildet sind, und keine herkömmlichen Glühlampen im Innenraum zur Anwendung kommen.Accordingly, the lighting device comprises illuminants which are connected to at least a portion of the console or are integrated in this. With such an arrangement it is avoided that only one essentially punctiform place in the interior of the household appliance whose interior is illuminated. Rather, the lighting device according to the invention is used Illumination of the interior of at least one partial area the console. In addition, the heat input into the interior is reduced that the lamps are formed on the console or integrated in it are, and no conventional light bulbs are used in the interior.

Gemäß einer Ausführungsform der Erfindung umfassen die Leuchtmittel eine Leuchtstoffröhre, welche sich besonders durch einen sehr geringen Wärmeeintrag in den Innenraum des Haushaltsgerätes auszeichnet.According to one embodiment of the invention, the lighting means comprise a Fluorescent tube, which is particularly characterized by a very low heat input in the interior of the household appliance.

Alternativ können die Leuchtmittel eine Anordnung mehrerer Leuchtdioden umfassen. Dabei lassen sich beispielsweise 10 bis 100 Leuchtdioden in der Form eines Leuchtdioden-Arrays anordnen. Leuchtdioden zeichnen sich durch einen sehr geringen Energieverbrauch, geringen Wärmeeintrag und hohe Lebensdauer aus.Alternatively, the lighting means can comprise an arrangement of a plurality of light-emitting diodes. For example, 10 to 100 LEDs can be shaped Arrange a light-emitting diode array. LEDs are characterized by a very low energy consumption, low heat input and long service life out.

Die verwendeten Leuchtdioden sind in unterschiedlichen Farben erhältlich, so dass das abgestrahlte Licht in einem dementsprechenden Farbton erscheint.

Dazu können auch alle weiteren, gemäß anderer Aufführungsformen verwendeten Leuchtmittel selbst oder an den Leuchtmitteln angebrachte Filtereinrichtungen farbig gestaltet sein. Mit der unterschiedlichen Farbgebung des abgestrahlten Lichts lassen sich verschiedene gestalterische Varianten abweichend von herkömmlichen Beleuchtungseinrichten für Haushaltsgeräte realisieren.The LEDs used are available in different colors that the emitted light appears in a corresponding color. This allows certain associations, for example with the term "freshness" or suggest "coldness" through blue tones to the user. You can do this also all other illuminants used in accordance with other forms of performance themselves or filter devices attached to the lamps designed in color his. With the different colors of the emitted light, Different design variants deviating from conventional lighting equipment for household appliances.

Gemäß einer besonders bevorzugten Ausführungsform kann zumindest ein Teilbereich der Konsole selbst als ein Leuchtmittel ausgebildet sein. Hierdurch wird eine möglichst gleichmäßige Ausleuchtung des Innenraumes sichergestellt.According to a particularly preferred embodiment, at least one partial area the console itself can be designed as a lamp. This will Illumination of the interior is as uniform as possible.

Dabei kann zumindest ein Teilbereich der Konsole als ein Lichtleiter ausgebildet sein, in welchen sich das Licht einer Lichtquelle einkoppeln lässt. In besonders vorteilhafter Weise kann die zur Lichteinkopplung vorgesehene Lichtquelle außerhalb des Innenraums des Haushaltsgeräts angeordnet sein. Da sich bei einer derartigen Anordnung die Lichtquelle, die im Betrieb Wärme abgibt, nicht innerhalb des Innenraumes befindet, sondern die Lichteinkopplung außerhalb desselben vorgenommen wird, wird der Wärmeeintrag durch das Leuchtmittel in den Innenraum vollständig vermieden.At least a portion of the console can be designed as a light guide in which the light from a light source can be coupled. Especially The light source provided for coupling in light can advantageously be outside of the interior of the household appliance. Since one such an arrangement, the light source that emits heat during operation is not within of the interior, but the coupling of light outside of it is made, the heat input by the illuminant in the Interior completely avoided.

Für die Einkopplung des Lichts in den Lichtleiter kann ein Kopplungselement zwischen der Lichtquelle und dem Lichtleiter angeordnet sein. Dabei lässt sich zusätzlich ein am Kopplungselement oder am Lichtleiter angeordnetes Filterelement vorsehen, welches selbst bei Verwendung einer herkömmlichen weißen Glühlampe farbiges Licht erzeugt und einkoppelt.A coupling element can be used to couple the light into the light guide be arranged between the light source and the light guide. It can be done additionally a filter element arranged on the coupling element or on the light guide provide, which even when using a conventional white Incandescent lamp generates and couples colored light.

In besonders einfacher Ausgestaltung kann der als Lichtleiter ausgebildete Teil der Konsole aus einem farbigen, lichtdurchlässigen Material, beispielsweise Glas oder Kunststoff bestehen. Der Einsatz farbiger Leuchtmittel ist somit nicht notwendig. Bei Ausfall des Leuchtmittels kann daher ein billiges, mit weißem Licht leuchtendes, herkömmliches Leuchtmittel, beispielsweise eine Glühlampe oder eine Leuchtstoffröhre im Austausch verwendet werden.In a particularly simple embodiment, the part designed as a light guide can the console made of a colored, translucent material, such as glass or plastic. The use of colored lamps is therefore not necessary. If the lamp fails, it can be a cheap, white light luminous, conventional illuminant, for example an incandescent lamp or a fluorescent tube can be used in exchange.

Gemäß einer bevorzugten Ausführungsform weist die Konsole eine Profilschiene auf, die im wesentlichen vertikal verlaufend im Innenraum des Haushaltsgeräts montiert ist. An der Profilschiene ist ein Trägerelement zur Halterung eines Tragbodens vorgesehen. Das Trägerelement lässt sich entlang der Profilschiene verschieben oder kann an der Profilschiene festgelegt werden. Dabei können beispielsweise Klemm- oder Rastverbindungen verwendet werden.
