Description

Die vorliegende Erfindung betrifft ein Kühl- und/oder Gefriergerät gemäß dem Oberbegriff des Anspruchs 1. Ein solches gerät ist allgemein bekannt.The present invention relates to a refrigerator and / or freezer according to the preamble of claim 1. Such a device is well known.

Aus dem Stand der Technik ist es bekannt, den Innenraum, d.h. den Kühl- und/oder Gefrierraum von Kühl- und/oder Gefriergeräten, zu beleuchten, wobei die Beleuchtungseinheit im allgemeinen im Innenraum des Gerätes angeordnet ist und aktiviert wird, wenn die Tür oder Klappe des Gerätes geöffnet wird.It is known from the prior art to use the interior, i. the cooling and / or freezing compartment of refrigerators and / or freezers to illuminate, the lighting unit is generally located in the interior of the device and is activated when the door or flap of the device is opened.

Aus der US 4,917,256 ist dabei eine Kühltruhe bekannt, welche aus mehreren, zusammensetzbaren Isolierpaneelen aufgebaut ist. Zur Kühlung der Kühltruhe ist eine Seitenwand als abnehmbares Kühlaggregat aus Verdichter und Verdampfer aufgebaut, an welchem auch die Beleuchtungsmittel zur Beleuchtung des Innenraums der Kühltruhe angeordnet sind.From the US 4,917,256 In this case, a freezer is known, which is composed of several, composable Isolierpaneelen. For cooling the freezer a side wall is constructed as a removable cooling unit of compressor and evaporator, on which the lighting means are arranged to illuminate the interior of the cabinet.

Aus DE 3925676 A1 ist eine Kühlvitrine mit einem Kühlgehäuse bekannt, welches an einer Seite zum Einschieben eines Rollcontainers offen ist. Dabei ist an der Oberseite der Kühlvitrine ein vollständiges Kühlaggregat aus Verdichter und Verdampfer abhebbar angeordnet, welches an seiner Unterseite Beleuchtungsmittel zur Beleuchtung der in der Kühlvitrine angeordneten Ware aufweist.Out DE 3925676 A1 a refrigerated display case with a cooling housing is known which is open on one side for insertion of a roll container. In this case, a complete cooling unit of compressor and evaporator is arranged liftable at the top of the refrigerated display case, which has on its underside illumination means for illuminating the goods arranged in the refrigerated display case.

Aus dem Stand der Technik ist es weiterhin bekannt, aufklappbare Beleuchtungen einzusetzen, die beim Öffnen und Schließen der Tür ein- und ausgeschwenkt werden. Diese mechanischen Lösungen haben allerdings den Nachteil, dass sie teuer sind und dass die Mechanik vergleichsweise störanfällig ist.From the prior art, it is also known to use hinged lights that are switched on and swung when opening and closing the door. However, these mechanical solutions have the disadvantage that they are expensive and that the mechanism is relatively prone to failure.

Aus der WO-A1-2007/062910 (im Stand der Technik gemäß Artikel 54(3) EPÜ) ist außerdem eine Kühl- und/oder Gefriergerät mit einem Innenbehälter und mit wenigstens einem Verdampfermodul zur Kühlung des Innenraums des Gerätes bekannt, wobei das Verdampfermodul in einem oberen Bereich des Innenraums unmittelbar unter der Decke des Innenbehälters angeordnet ist und somit den oberen Abschluss des Innenraums des Kühl- und/oder Gefriergerätes bildet, sowie mit Beleuchtungsmitteln, mittels derer der Innenraum des Gerätes wenigstens teilweise beleuchtbar ist, wobei die Beleuchtungsmittel in dem Verdampfermodul angeordnet sind.From the WO-A1-2007 / 062910 (In the prior art under Article 54 (3) EPC) is also a refrigerator and / or freezer with an inner container and at least one evaporator module for cooling the interior of the device known, the evaporator module in an upper region of the interior immediately below Ceiling of the inner container is arranged and thus forms the upper end of the interior of the refrigerator and / or freezer, and with lighting means by which the interior of the device is at least partially illuminated, wherein the illumination means are arranged in the evaporator module.

Die Aufgabe der vorliegenden Erfindung besteht daher darin, ein Kühl- und/oder Gefriergerät der eingangs genannten Art dahingehend weiterzubilden, dass die Beleuchtung effizient und wenig störanfällig ausgeführt ist, und dass die Montage - Freundlichkeit des Geräts erhöht wird.The object of the present invention is therefore to develop a refrigerator and / or freezer of the type mentioned in such a way that the lighting is carried out efficiently and little susceptible to interference, and that the installation - friendliness of the device is increased.

Diese Aufgabe wird durch ein Kühl- und/oder Gefriergerät mit den Merkmalen des Anspruchs 1 gelöst. Danach ist vorgesehen, dass die Beleuchtungsmittel in dem Verdampfermodul angeordnet sind und dass in dem Kühl-und/oder Gefriergerät transparente Böden oder Schubladen eingesetzt sind. Erfindungsgemäß ist somit vorgesehen, dass die Beleuchtung in das Verdampfermodul integriert ist, dass somit eine Kombination aus Beleuchtung und Verdampfermodul eingesetzt wird.This object is achieved by a refrigerator and / or freezer with the features of claim 1. Thereafter, it is provided that the illumination means are arranged in the evaporator module and that in the refrigerator and / or freezer transparent trays or drawers are used. According to the invention it is thus provided that the lighting is integrated into the evaporator module, that thus a combination of lighting and evaporator module is used.

Die Vorteile einer Baugruppe aus Beleuchtungsmitteln und Verdampfermodul sind u. a. Kostenvorteile durch einfachere Montage und geringere Teilevielfalt sowie ein geringerer Konstruktionsaufwand der kompletten Baugruppe mit Verdampfermodul und Beleuchtung.The advantages of an assembly of lighting means and evaporator module are u. a. Cost advantages through simpler installation and less variety of parts and a lower design effort of the complete assembly with evaporator module and lighting.

In der folgenden Beschreibung steht der Begriff des "aus Sicht des Benutzers vor dem Innenraum des Gerätes befindliche Bereichs" für einen beliebigen Bereich vor dem Geräteinnenraum, der z. B. den Bereich umfassen kann, in dem sich ausgezogene Böden oder Schubladen befinden, so dass die Beleuchtung in dieser Ausführungsform unter anderem dazu dient, die in den Schubladen bzw. auf den Böden befindlichen Waren zu beleuchten. Auch der Bereich, in dem sich die geöffnete Tür befindet, kann erfasst sein. So ist es beispielsweise denkbar, dass die Beleuchtungsmittel des erfindungsgemäßen Kühl- und/oder Gefriergerätes zusätzlich zu der Beleuchtung des Innenraums auch zu einer Beleuchtung der Innenseite der geöffneten Gerätetür, beispielsweise zu einer Beleuchtung der Türabsteller, dienen können.In the following description is the concept of "from the user's point of view in front of the interior of the device located area" for any area in front of the device interior, the z. B. may include the area in which solid floors or drawers are, so that the lighting in this embodiment, among other things, serves in the drawers or on the floors to illuminate the goods. The area in which the opened door is located can also be detected. So it is conceivable, for example, that the lighting means of the refrigerator and / or freezer according to the invention in addition to the illumination of the interior also to a lighting of the inside of the open door, for example, to a lighting of the door racks serve.

Die Beleuchtungsmittel umfassen eine oder mehrere LEDs. In weiterer Ausgestaltung der Erfindung ist vorgesehen, dass die Beleuchtungsmittel durch eine oder mehrere LEDs gebildet werden. LEDs haben u. a. den Vorteil, dass sie klein sind und auch deshalb in beengten Raumverhältnissen eingesetzt werden können, da LEDs eine vergleichsweise geringe Wärmeentwicklung aufweisen. Durch die Verwendung einer oder mehrerer LEDs sind somit auch Anordnungen der Beleuchtung bei sehr beengten Platzverhältnissen möglich.The illumination means comprise one or more LEDs. In a further embodiment of the invention it is provided that the illumination means are formed by one or more LEDs. LEDs have u. a. the advantage that they are small and therefore can be used in confined spaces, since LEDs have a relatively low heat. By using one or more LEDs, it is thus also possible to arrange the lighting in very tight spaces.

Weiterhin kann eine Bedien- und/oder Steuereinheit vorgesehen sein, die innerhalb oder auch außerhalb des Gerätes angeordnet ist. Denkbar ist es beispielsweise, die Bedien- und/oder Steuereinheit oberhalb des gekühlten Geräteinnenraums in Form einer frontseitigen Leiste auszubilden. Denkbar ist, dass die Bedien- und/oder Steuereinheit oberhalb des gekühlten Geräteinnenraums angeordnet ist. Sie kann beispielsweise in einem Bereich angeordnet sein, der bei geschlossener Tür durch diese verdeckt ist.Furthermore, an operating and / or control unit may be provided, which is arranged inside or outside the device. It is conceivable, for example, to form the operating and / or control unit above the refrigerated appliance interior in the form of a front strip. It is conceivable that the operating and / or control unit is arranged above the refrigerated device interior. It may, for example, be arranged in an area which is covered by the door when it is closed.

In weiterer Ausgestaltung der Erfindung ist vorgesehen, dass das Verdampfermodul eine Ausnehmung aufweist und dass die Beleuchtungsmittel derart angeordnet sind, dass sie durch die Ausnehmung Licht abgeben.In a further embodiment of the invention, it is provided that the evaporator module has a recess and that the illumination means are arranged such that they emit light through the recess.

Weiterhin kann vorgesehen sein, dass sich die Beleuchtungsmittel auf der Unterseite oder Frontseite des Verdampfermoduls befinden oder dass sich die Beleuchtungsmittel innerhalb des Verdampfermoduls befinden und derart angeordnet sind, dass die Ausnehmung in der Unterseite oder Frontseite des Verdampfermoduls angeordnet ist. Denkbar ist somit beispielsweise, das Verdampfermodul Augenhöhe anzuordnen, und die Beleuchtung derart vorzusehen, dass diese bei geöffneter Tür des Gerätes nach unten und/oder vorne Licht abgibt.Furthermore, it can be provided that the illumination means are located on the underside or front side of the evaporator module or that the illumination means are located inside the evaporator module and are arranged such that the recess is arranged in the underside or front side of the evaporator module. It is thus conceivable, for example, the evaporator module To arrange eye level, and provide the lighting so that it emits light with the door open the device down and / or forward.

Das Verdampfermodul kann eine Blende aufweisen, die zumindest die frontseitige Abdeckung des Verdampfermoduls bildet. Denkbar ist, dass die Beleuchtungsmittel in oder an der Blende angeordnet sind, sowie auch, dass die Ausnehmung, durch die das Licht abgegeben wird, in der Blende angeordnet ist.The evaporator module may have a diaphragm which forms at least the front cover of the evaporator module. It is conceivable that the illumination means are arranged in or on the diaphragm, as well as that the recess through which the light is emitted, is arranged in the diaphragm.

In weiterer Ausgestaltung der Erfindung ist vorgesehen, dass die Beleuchtungsmittel oder eine Beleuchtungseinheit, die die Beleuchtungsmittel umfasst, flächenbündig mit dem Verdampfermodul bzw. der Blende abschließt oder gegenüber dieser hervorstehend ist. Die Beleuchtung kann somit unauffällig, flächenbündig oder beispielsweise auch leicht hervorstehend ausgeführt werden. Wie ausgeführt, sind durch die Verwendung eines oder mehrerer LED-Leuchtkörper auch Ausführungen in sehr beengten Platzverhältnissen möglich.In a further embodiment of the invention, it is provided that the illumination means or a lighting unit, which comprises the illumination means, is flush with the evaporator module or the panel or protruding therefrom. The lighting can thus be performed unobtrusively, flush or for example slightly protruding. As stated above, the use of one or more LED luminaires also makes possible designs in very tight spaces.

In weiterer Ausgestaltung der Erfindung ist vorgesehen, dass die Beleuchtung durch zwei oder mehr als zwei Leuchtkörper bereitgestellt wird, die derart angeordnet sind, dass sie in unterschiedlichen Richtungen Licht abgeben. Durch unterschiedliche Abstrahlwinkel des Lichtes besteht die Möglichkeit, Lichteffekte genau fokussiert mit Tiefenwirkung, beispielsweise auf Schubladen zu bringen, zusätzlich zu der Beleuchtung des Innenraums des Gerätes.In a further embodiment of the invention it is provided that the illumination is provided by two or more than two luminous bodies, which are arranged such that they emit light in different directions. Due to the different angles of the light, it is possible to bring lighting effects precisely focused with depth effect, for example on drawers, in addition to the illumination of the interior of the device.

In weiterer Ausgestaltung der Erfindung ist vorgesehen, dass das Verdampfermodul eine Blende aus transparentem Material aufweist. Es kann somit ein transparenter Werkstoff für die Blende verwendet werden, was den Vorteil mit sich bringt, dass eine etwaige Abdeckung der Beleuchtungseinheit sowie die genannte Blende aus einem Teil gefertigt werden können. Dabei kann vorgesehen sein, dass Bereiche der Blende, die nicht transparent sein sollen, durch Bedrucken, Lackieren bzw. in einem Spritzprozeß über das Inmould-Verfahren abgedeckt werden.In a further embodiment of the invention, it is provided that the evaporator module has a diaphragm of transparent material. It can thus be used a transparent material for the panel, which has the advantage that any cover of the lighting unit and said aperture can be made of one part. It can be provided that areas of the diaphragm, which should not be transparent, are covered by printing, painting or in an injection process via the in-mold process.

Die erfindungsgemäße Anordnung von Beleuchtungsmitteln in dem Verdampfermodul bringt den Vorteil mit sich, dass bestimmte Lichteffekte erzeugt werden können. So ist es beispielsweise denkbar, Logos, Symbole und Bedruckungen und dergleichen durch Hinterleuchtung hervorzuheben. Dies kann beispielsweise durch Ausnutzen von Streulicht der genannten Beleuchtung im Innenraum der Blende erfolgen oder auch durch eine gezielte Hinterleuchtung, beispielsweise durch Anbringen von Lichtleitern, die von den Beleuchtungsmitteln ausgehen.The inventive arrangement of illumination means in the evaporator module has the advantage that certain lighting effects can be generated. Thus, it is conceivable, for example, to highlight logos, symbols and imprints and the like by backlighting. This can be done for example by exploiting stray light of the mentioned illumination in the interior of the diaphragm or by a targeted backlighting, for example by attaching light guides, which emanate from the illumination means.

In weiterer Ausgestaltung der Erfindung ist vorgesehen, dass die Beleuchtungsmittel an eine elektrische Baugruppe angeschlossen sind, die außer der Versorgung der Beleuchtungsmittel wenigstens ein weiteres Bauteil steuert oder versorgt. Die Beleuchtungsmittel, die zur Beleuchtung benötigt werden, können auf eine bereits vorhandene Platine der Baugruppe mitintegriert werden. Eine eigene Platine für die Beleuchtung ist somit nicht erforderlich. Damit wird eine kostengünstige Einheit durch die Verwendung einer bestehenden Platine plus Beleuchtung geschaffen. Es ist ebenfalls möglich, bei der Beleuchtung in dem Verdampfermodul auf vorhandene Standardbaugruppen zurückzugreifen. Dies können beispielsweise standardisierte Bauteile oder bereits in anderen Geräten verwendete Beleuchtungs-Baugruppen, insbesondere LED-Beleuchtungs-Baugruppen sein.In a further embodiment of the invention it is provided that the illumination means are connected to an electrical assembly which controls or supplies at least one further component in addition to the supply of the illumination means. The lighting devices that are needed for lighting can be integrated on an existing board of the module. A separate board for lighting is therefore not required. This creates a cost-effective unit through the use of an existing board plus lighting. It is also possible to resort to existing standard assemblies when lighting in the evaporator module. These may be, for example, standardized components or lighting assemblies already used in other devices, in particular LED lighting assemblies.

Das Verdampfermodul des Kühl- und/oder Gefriergerätes gemäß der Erfindung ist in einem oberen Bereich des Innenraums, d. h. unmittelbar unter der Decke des Innenbehälters angeordnet und bildet somit den oberen Abschluss des Innenraums des Kühl- und/oder Gefriergerätes.The evaporator module of the refrigerator and / or freezer according to the invention is in an upper portion of the interior, d. H. placed immediately under the ceiling of the inner container and thus forms the upper end of the interior of the refrigerator and / or freezer.

Like this FIG. 1 and 2 As can be seen, the LEDs are arranged such that they emit light down through the located in the bottom of the aperture recess 20 and thus the interior of the refrigerator and / or freezer and from the user's point of view in front of the interior area, in particular the interior illuminated drawers or solid floors, as this particular FIG. 2 evident.

In Figur 3 ist nun ein Ausführungsbeispiel der vorliegenden Erfindung dargestellt. Dabei ist in dem Verdampfermodul 30, das sich an oberster Stelle in dem Innenbehälter des Gefriergerätes befindet, eine mit einer oder mehreren LEDs ausgeführte Beleuchtungseinheit angeordnet, mittels derer Licht nach unten und/oder vorne abgegeben wird. Auf diese Weise ist es möglich, den Innenraum des Kühl- bzw. Gefriergerätes und gegebenenfalls den vor diesem befindlichen Bereich auszuleuchten.In FIG. 3 Now, an embodiment of the present invention is shown. Here, in the evaporator module 30, which is located at the highest point in the inner container of the freezer, arranged with one or more LEDs lighting unit arranged by means of which light is emitted down and / or forward. In this way it is possible to illuminate the interior of the refrigerator or freezer and, where appropriate, the area located in front of this.

Grundsätzlich kann selbstverständlich auch vorgesehen sein, dass die Beleuchtung in dem Verdampfermodul 30 auf dessen Unterseite angeordnet ist, so dass das Licht überwiegend nach unten abgegeben wird.In principle, it can of course also be provided that the illumination is arranged in the evaporator module 30 on its underside, so that the light is emitted predominantly downwards.

Erfindungsgemäß werden transparente Böden bzw. Schubladen eingesetzt. Damit ergibt sich der Vorteil, dass durch diese das Licht hindurch auch in untere Bereiche des Geräteinnenraums dringt.According to the invention, transparent trays or drawers are used. This results in the advantage that through this the light penetrates into lower areas of the device interior.

Die Beleuchtungsmittel des erfindungsgemäßen Kühl- und/oder Gefriergerätes können derart bewegbar ausgeführt sein, dass der ausgeleuchtete Bereich durch den Benutzer veränderbar ist, so dass besonders bevorzugte Bereiche des Gerätes ausgeleuchtet werden können.The illumination means of the refrigerator and / or freezer according to the invention can be made movable such that the illuminated area can be changed by the user, so that particularly preferred areas of the device can be illuminated.
