Description

Die vorliegende Erfindung betrifft ein Kühlmöbel, das der Aufnahme und Präsentation von zu kühlenden Waren, vor-zugsweise Lebensmitteln, dient, welches einen Aufnahmeraum für Waren und wenigstens eine Tür, beispielsweise in Form einer Schiebe- oder Schwenktür, die zwischen einer Offen- und einer Schließstellung bewegbar, beispielsweise verschiebbar oder verschwenkbar, ist, so dass der Aufnahmeraum von außen zugänglich ist, umfasst.The present invention relates to a refrigeration unit which is used to hold and present goods to be cooled, preferably food, which has a receiving space for goods and at least one door, for example in the form of a sliding or pivoting door, which is positioned between an open and a The closed position is movable, for example displaceable or pivotable, so that the receiving space is accessible from the outside, includes.

Entsprechende Kühlmöbel sind beispielsweise in der US 2008/148753 A1 , oder der JP 2005 207680 A beschrieben.Corresponding refrigeration units are for example in the US 2008/148753 A1 , or the JP 2005 207680 A described.

Das Kühlmöbel zeichnet sich dadurch aus, dass im Bereich unter- und/oder oberhalb der Tür ein oder mehrere Lichtleitelemente angeordnet sind, die mit zumindest einer Lichtquelle in Wirkverbindung stehen und von außen sichtbar sind.The refrigeration unit is characterized in that one or more light guide elements are arranged in the area below and / or above the door, which are in operative connection with at least one light source and are visible from the outside.

Das Lichtleitelement kann beispielsweise durch eine Glas- oder Plexiglasplatte gebildet sein, die das Warenpräsentationsmöbel beispielsweise zumindest teilweise nach oben hin abschließt. Die Platte weist in diesem Fall zumindest eine nach vorne gerichtete Stirnseite (= Lichtaustrittsfläche) auf, über die das mit Hilfe der Lichtquelle (z. B. einer oder mehrerer LEDs), vorzugsweise von unten oder hinten, über ein Lichteinkoppelfläche eingebrachte Licht wieder aus der Platte austreten kann. Im Ergebnis besitzt ein entsprechend ausgerüstetes und erfindungsgemäßes Kühlmöbel ein von vorne für den Kunden sichtbares Lichtband, dessen Farbe beispielsweise in Abhängigkeit der präsentierten Waren gewählt werden kann (z. B. blau für Fischprodukte oder gelb für Obst).The light guide element can be formed, for example, by a glass or plexiglass plate, which closes the product display furniture, for example, at least partially towards the top. In this case, the plate has at least one front face (= light exit surface), via which the light introduced with the help of the light source (e.g. one or more LEDs), preferably from below or behind, via a light coupling surface again from the Plate can leak. As a result, an appropriately equipped and inventive refrigeration cabinet has a front view for the customer visible light band, the color of which depends, for example, on the presented goods can be selected (e.g. blue for fish products or yellow for fruit).

Ferner ist vorgesehen, dass der kürzeste Abstand zwischen der genannten Lichteinkoppelfläche und der Lichtaustrittsfläche derart bemessen ist, dass sich das von den einzelnen LEDs emittierte Licht innerhalb des Lichtleitelements, d. h vor dem Austritt aus demselben, schneidet. Das Licht tritt in diesem Fall nicht in Form einzelner Lichtpunkte oder Lichtlinien aus dem Lichtleitelement aus. Vielmehr ist sichergestellt, dass das von den LEDs abgestrahlte Licht verschmilzt und bei einer entsprechend linienförmig ausgebildeten Lichtauskoppelfläche ein Lichtband bildet.Furthermore, it is provided that the shortest distance between the mentioned light coupling surface and the light exit surface is dimensioned such that the light emitted by the individual LEDs is within the light guide element, i. h before exiting it, cuts. In this case, the light does not emerge from the light guide element in the form of individual points of light or lines of light. Rather, it is ensured that the light emitted by the LEDs merges and forms a light band with a light coupling-out surface configured in a correspondingly linear manner.

Auch ist es von Vorteil, wenn die Lichteinkoppelfläche eine geringere Oberflächenrauheit aufweist als die Lichtaustrittsfläche. Insbesondere sollte die zuletzt genannte Fläche aufgeraut oder mattiert sein, um eine Lichtstreuung des aus dem Lichtleitelement austretenden Lichts zu bewirken.It is also advantageous if the light coupling surface has a lower surface roughness than the light exit surface. In particular, the last-mentioned surface should be roughened or matted in order to effect light scattering of the light emerging from the light-guiding element.

Von Vorteil ist es, wenn die Glas- oder Plexiglasplatte das Kühlmöbel zumindest teilweise nach oben hin abschließt. Beispielsweise wäre es denkbar, dass die Glas- oder Plexiglasplatte einen Deckenbereich des Warenpräsentationsmöbels bildet, so dass auch das aus der Glas- oder Plexiglasplatte austretende Licht im oberen Bereich des Kühlmöbels sichtbar ist und einen oberen Abschluss desselben bildet.It is advantageous if the glass or Plexiglas plate closes the refrigeration unit at least partially at the top. For example, it would be conceivable that the glass or Plexiglas plate forms a ceiling area of the product presentation furniture, so that the light emerging from the glass or Plexiglas plate is visible in the upper area of the refrigerated cabinet and forms an upper end of the same.

Insbesondere ist es zudem von Vorteil, wenn die Tür in ihrem oberen Bereich direkt über ein Scharnier, beispielsweise über einen Drehbolzen, in einer Ablage oder einem sonstigen oberen und vorzugsweise flächig ausgebildeten Abschlusselement des Kühlmöbels gelagert ist. Hierbei ist es zudem von Vorteil, wenn das Lichtleitelement durch die Ablage bzw. das obere Abschlusselement oder ein zwischen der Tür und der Ablage oder zwischen der Tür und dem Abschlusselement angeordnetes Zwischenelement gebildet ist.In particular, it is also advantageous if the door is mounted in its upper area directly via a hinge, for example via a pivot pin, in a shelf or some other upper and preferably flat closing element of the refrigeration unit. It is also advantageous here if the light-guiding element is formed by the shelf or the upper closing element or an intermediate element arranged between the door and the shelf or between the door and the closing element.

Zusätzlich oder alternativ können selbstverständlich auch im unteren oder seitlichen Bereich des Kühlmöbels ein oder mehrere entsprechende Lichtleitelemente platziert sein.In addition or as an alternative, one or more corresponding light guide elements can of course also be placed in the lower or side area of the refrigerated cabinet.

Ebenso ist es möglich, dass die Tür in ihrem oberen Bereich über einen Bolzen geführt ist. Dieser Bolzen verfügt vorzugsweise über eine glatte Oberfläche, über die er in einer entsprechenden Führung des Kühlmöbels geführt ist. Die Führung kann z. B. durch eine Durchbrechung, vorzugsweise eine Bohrung, eines transparenten bzw. zumindest teilweise transparenten oberen Halteelements des Kühlmöbels gebildet sein. Denkbar ist beispielsweise, dass im oberen Bereich eine horizontal oder leicht schräg angeordnete Glasplatte oder eine Platte aus einem anderen transparenten Material angeordnet ist, das die genannten Bohrungen aufweist und durch die sich die oberen Bolzen der entsprechenden Türen erstrecken.It is also possible for the door to be guided over a bolt in its upper area. This bolt preferably has a smooth surface over which it is guided in a corresponding guide of the refrigerated cabinet. The guide can e.g. B. be formed by an opening, preferably a bore, of a transparent or at least partially transparent upper holding element of the refrigeration unit. It is conceivable, for example, that a horizontally or slightly inclined glass plate or a plate made of another transparent material is arranged in the upper area, which has the bores mentioned and through which the upper bolts of the corresponding doors extend.

Gleichartige Bauteile sind in den einzelnen Figuren mit denselben Bezugszeichen versehen, wobei in den Figuren 1 bis 3 gleichartige Elemente aus Gründen einer besseren Übersichtlichkeit stets nur einmal mit einem Bezugszeichen versehen sind (beispielsweise besitzen die in den Figuren 1 bis 3 gezeigten Kühlmöbel 10 offensichtlich mehrere Türen 3 mit daran befestigten Griffen 11).Similar components are provided with the same reference numerals in the individual figures, with Figures 1 to 3 Similar elements are always provided with a reference number only once for the sake of clarity (for example, those in FIGS Figures 1 to 3 The refrigeration cabinet 10 shown obviously has several doors 3 with handles 11) attached thereto.

Beschrieben wird ein Kühlmöbel 10, das daher einen entsprechenden Kältemittelkreislauf besitzt, der jedoch in den Figuren 1 bis 3, die entsprechende Kühlmöbel 10 zeigen, aus Übersichtsgründen nicht dargestellt ist.A refrigeration unit 10 is described, which therefore has a corresponding refrigerant circuit, but which is in the Figures 1 to 3 , which show corresponding refrigeration units 10, is not shown for reasons of clarity.

Figur 4 zeigt einen Ausschnitt einer teilweise geschnittenen Seitenansicht eines Kühlmöbels 10 mit einem Rahmen 2, einer einen Aufnahmeraum 7 verschließenden Tür 3, die um eine waagrechte Drehachse zu öffnen bzw. zu schließen ist und mit mehreren Regalböden 4. Figure 4 shows a detail of a partially sectioned side view of a refrigerated cabinet 10 with a frame 2, a door 3 which closes a receiving space 7 and which can be opened or closed about a horizontal axis of rotation and with several shelves 4.

Figur 4 zeigt darüber hinaus, dass die Tür 3 generell in ihrem oberen Bereich direkt über ein Scharnier 1, beispielsweise über einen Drehbolzen, in einer Ablage 6 bzw. einem sonstigen oberen Abschlusselement (das vorzugsweise flächig ausgebildet ist) des Kühlmöbels gelagert sein kann, wobei die Ablage 6 wiederum, zumindest großteils, aus Glas oder einem sonstigen lichtdurchlässigen Material gefertigt sein kann, so dass beim Blick auf das Kühlmöbel nahezu ausschließlich Glas- bzw. lichttransparente Flächen zu sehen sind. Figure 4 also shows that the door 3 can generally be mounted in its upper area directly via a hinge 1, for example via a pivot pin, in a shelf 6 or some other upper closing element (which is preferably flat) of the refrigerated cabinet, the shelf 6 can in turn be made, at least for the most part, of glass or some other translucent material, so that when looking at the refrigeration unit, almost exclusively glass or light-transparent surfaces can be seen.

Generell ist es in diesem Zusammenhang denkbar, dass die Ablage 6 bzw. ein oberes Abschlusselement oder ein zwischen den Türen 3 und der Ablage 6 oder zwischen den Türen 3 und dem Abschlusselement angeordnetes Zwischenelement lichtleitend ausgebildet ist.In general, it is conceivable in this context that the shelf 6 or an upper closing element or between the doors 3 and the shelf 6 or between the doors 3 and the closing element arranged intermediate element is formed light-conducting.

Das entsprechende Lichtleitelement 9 kann beispielsweise plattenförmig ausgebildet sein und zumindest teilweise aus Glas oder Plexiglas bestehen. Wird das Lichtleitelement 9, wie in Figur 4 angedeutet, von hinten mit Hilfe einer Lichtquelle 15 (z. B. einer oder mehrerer LEDs 8) angestrahlt, so wird das Licht bis in den vorderen, vom Kunden sichtbaren, Teil des Lichtleitelements 9 geleitet. Im Ergebnis ist von vorne (in Figur 4: von links) ein linienförmiges Lichtband für den Kunden sichtbar, das beispielsweise als Indikator für die in dem Kühlmöbel gelagerten Waren dienen kann (z. B. blaues Licht für Meeresfrüchte, grünes Licht für Gemüse, usw.).The corresponding light guide element 9 can for example be designed in the form of a plate and at least partially consist of glass or Plexiglas. If the light guide element 9, as in Figure 4 indicated, illuminated from behind with the aid of a light source 15 (for example one or more LEDs 8), the light is guided into the front part of the light guide element 9 that is visible to the customer. The result is from the front (in Figure 4 : from the left) a line-shaped light band visible to the customer, which can for example serve as an indicator for the goods stored in the refrigerated cabinet (e.g. blue light for seafood, green light for vegetables, etc.).

Zusätzlich oder alternativ können selbstverständlich auch im Bereich unterhalb der Türen 3 ein oder mehrere Lichtleitelemente 9 vorhanden sein, die sich von vorne gesehen vorzgusweise ebenfalls in Breitenrichtung des KühImöbels erstrecken.In addition or as an alternative, one or more light guide elements 9 can of course also be present in the area below the doors 3, which, viewed from the front, preferably also extend in the width direction of the refrigerator.

Figur 5 zeigt nun eine Draufsicht auf ein erfindungsgemäßes Lichtleitelement 9. Das im gezeigten Beispiel plattenförmige Lichtleitelement 9 ist einer Vielzahl von die Lichtquelle 15 bildenden LEDs 8 benachbart angeordnet und weist eine Lichteinkoppelfläche 14 auf, über die das von den LEDs 8 in deren Betrieb (d. h in eingeschaltetem Zustand) emittierte Licht in das Lichtleitelement 9 eingekoppelt wird (d. h. in dieses eintritt). Figure 5 now shows a plan view of a light guide element 9 according to the invention. The plate-shaped light guide element 9 in the example shown is arranged adjacent to a multiplicity of LEDs 8 forming the light source 15 and has a light coupling surface 14 via which the light from the LEDs 8 in their operation (i.e. in the switched-on state) light emitted is coupled into the light guide element 9 (ie enters this).

Ebenso ist eine Lichtaustrittsfläche 5 vorhanden, über die das eingekoppelte Licht wieder aus dem Lichtleitelement 9 austritt und schließlich für den Betrachter sichtbar wird. Während die Lichteinkoppelfläche 14 möglichst glatt ausgebildet sein sollte, um Lichtverluste zu vermeiden, hat es sich bewährt, die Lichtaustrittsfläche 5 anzurauen bzw. zu mattieren. Hierdurch wird das Licht beim Austritt aus dem Lichtleitelement 9 teilweise gestreut, so dass sich ein möglichst homogenes Lichtband im Bereich der Lichtaustrittsfläche 14 bildet.There is also a light exit surface 5 via which the coupled-in light exits the light-guiding element 9 and is finally visible to the viewer. While the light coupling surface 14 should be designed to be as smooth as possible in order to avoid light loss, it has proven useful to roughen or mattify the light exit surface 5. As a result, the light is partially scattered when it emerges from the light guide element 9, so that forms a light band that is as homogeneous as possible in the area of the light exit surface 14.

Um sicherzustellen, dass das von der Lichtquelle 15 erzeugte Licht für den Betrachter tatsächlich als Lichtband und nicht als einzelne Lichtpunkte wahrgenommen wird, ist der kürzeste Abstand A zwischen der Lichteinkoppelfläche 14 und der Lichtaustrittsfläche 15 derart bemessen ist, dass sich die von den LEDs erzeugten Lichtkegel 12 bzw. ein Teil der emittierten Lichtstrahlen 13 (in den Figuren 6 und 7 lediglich schematisch angedeutet) zwischen der Lichteinkoppelfläche 14 und Lichtaustrittsfläche 15 wenigstens abschnittsweise schneiden.To ensure that the light generated by the light source 15 is actually perceived by the viewer as a band of light and not as individual points of light, the shortest distance A between the light coupling surface 14 and the light exit surface 15 is dimensioned such that the light cones generated by the LEDs are arranged 12 or part of the emitted light rays 13 (in the Figures 6 and 7th only indicated schematically) cut between the light coupling surface 14 and light exit surface 15 at least in sections.

Wäre dies nicht der Fall, so entstünden im Bereich der Lichtaustrittsfläche 15 Bereiche, in denen kein Licht aus dem Lichtleitelement 9 austreten. Das Licht würde in diesem, in Figur 7 gezeigten, Fall in Form mehrerer Lichtpunkte oder Lichtlinien wahrgenommen.If this were not the case, then in the area of the light exit surface 15 areas would arise in which no light emerges from the light guide element 9. The light would be in this, in Figure 7 the case shown in the form of several points of light or lines of light.
