Description

Die Erfindung betrifft ein zumindest teilweise gekühltes, nach vorne offenes Regal, bei dem die Kühlung des Regalwarenraumes mittels eines durch die zumindest teilweise perforierte Warenraumrückwand in den Warenraum strömenden Kühlluftschleiers und/oder mittels eines entlang der Warenraumöffnung strömenden Kühlluftschleiers bewirkt wird, und in dessen Warenraum ein oder mehrere Warenpräsentationsböden angeordnet sind, wobei die Warenpräsentationsböden derart ausgebildet sind, dass über sie zumindest ein Teilstrom des Kühlluftschleiers in den Bereich der Vorderfront der Warenpräsentationsböden geführt wird, und die Warenpräsentationsböden Mittel zum Stabilisieren wenigstens eines Teilstromes des entlang der Warenraumöffnung strömenden Kühlluftschleiers aufweisen.The invention relates to an at least partially cooled, forwardly open shelf, in which the cooling of the shelf space is effected by means of a flowing through the at least partially perforated goods room back wall in the goods space cooling air curtain and / or by means of a flowing along the goods space opening cooling air curtain, and in the goods space a or a plurality of goods display shelves are arranged, wherein the goods presentation trays are designed such that at least a partial flow of the cooling air curtain is guided in the region of the front of the Warenpräsentationsböden over them, and the Warenpräsentationsböden means for stabilizing at least a partial flow of flowing along the goods space opening cooling air curtain.

Aus der nicht vorveröffentlichten, deutschen Patentanmeldung 103 38 672 ist ein gattungsgemäßes Kühlregal bekannt. Der Offenbarungsgehalt dieser Patentanmeldung sei durch dieses Zitat zur Gänze in den Offenbarungsgehalt der vorliegenden Patentanmeldung aufgenommen.From the not previously published, German patent application 103 38 672 is a generic cooling rack known. The disclosure of this patent application is incorporated by this reference in its entirety in the disclosure of the present patent application.

Ein Kühlregal gemäss dem Oberbegriff von Anspruch 1 ist aus dem Dokument FR-A-2 690 825 bekannt.A refrigerated shelf according to the preamble of claim 1 is known from the document FR-A-2 690 825 known.

Gattungsgemäße zumindest teilweise gekühlte, nach vorne offene Regale - im Folgenden nunmehr als Kühlregal bezeichnet - sind aus dem Stand der Technik hinlänglich bekannt. Sie dienen, entsprechend ihrer kältetechnischen Auslegung, der Kühlung unterschiedlichster Produkte sowohl im so genannten Plus- als auch im so genannten Minusbereich. Hierbei wird die innerhalb des Kühlregales erzeugte Kühlluft, die für die Kühlung der präsentierten Waren erforderlich ist, durch die zumindest teilweise perforierte Warenraumrückwand ungerichtet in den Warenraum geleitet, während mittels des entlang der Warenraumöffnung strömenden Kühlluftschleiers eine Abschottung des gekühlten Warenraumes zu der wärmeren Umgebung(sluft) erfolgt.Generic at least partially cooled, open to the front shelves - hereinafter referred to as a cooling rack - are well known in the prior art. They serve, according to their cooling technology design, the cooling of various products in both the so-called plus and in the so-called minus range. Here, the cooling air generated within the cooling rack, which is required for the cooling of the presented goods, passed undirected through the at least partially perforated goods room back wall in the goods room, while by means of flowing along the goods space opening cooling air curtain foreclosure of the refrigerated goods space to the warmer environment (sluft ) he follows.

Der entlang der Warenraumöffnung strömende Kühlluftschleier wird hierbei entweder aus lediglich einem Luftschleier oder - mit entsprechend technischem Mehraufwand - aus zwei oder mehr, parallel strömenden Kühlluftschleiern gebildet.The cooling air curtain flowing along the goods space opening is formed here either from only one air curtain or - with correspondingly additional technical expenditure - from two or more cooling air curtains flowing in parallel.

Bekannt sind darüber hinaus gattungsgemäße Kühlregale, bei denen die Warenraumöffnungen mittels Klapp- und/oder Schiebetüren verschließbar sind. Derartige Kühlregale haben jedoch gegenüber Kühlregalen ohne Türen den Nachteil, dass der Zugriff auf die in ihnen präsentierten Waren erst nach dem Öffnen einer Tür möglich ist. Es hat sich gezeigt, dass der Abverkauf bei "offenen" Kühlregalen höher ist als bei "geschlossenen" Kühlregalen.Furthermore, generic refrigerated shelves are known in which the goods compartment openings can be closed by means of folding and / or sliding doors. However, such refrigerated shelves have the disadvantage over refrigerated shelves without doors that access to the goods presented in them is possible only after opening a door. It has been shown that sales are higher with "open" refrigerated shelves than with "closed" refrigerated shelves.

In jüngster Vergangenheit wird von den Abnehmern gattungsgemäßer Kühlregale verlangt, dass eine möglichst gleichmäßige Verteilung der Kühlluft innerhalb des Kühlregales bzw. des Warenraumes erreicht wird. Die Temperaturspreizung zwischen kalter und warmer Ware bei einer Mittelwerttemperatur der Ware von maximal 3,3 °C soll hierbei nicht mehr als 7,2 K betragen. Der Temperaturbereich der Ware soll zwischen 0 und 7,2°C liegen. Ferner müssen gattungsgemäße Kühlregale in der Lage sein, eine eingebrachte Ware innerhalb eines Zeitraumes von maximal 16 Stunden von Umgebungstemperatur auf eine Temperatur im Bereich von 0 bis 7,2 °C abzukühlen, wobei die Mittelwerttemperatur der Ware maximal 3,3 °C betragen darf.In recent years, the customers of generic refrigerated shelves is required that the most uniform distribution of the cooling air is achieved within the refrigerated shelf or the goods compartment. The temperature spread between cold and warm goods at a mean temperature of the product of a maximum of 3.3 ° C should not be more than 7.2 K here. The temperature range of the goods should be between 0 and 7.2 ° C. Furthermore, generic refrigerated shelves must be able to cool an introduced product within a period of a maximum of 16 hours from ambient temperature to a temperature in the range of 0 to 7.2 ° C, the average temperature of the product may be a maximum of 3.3 ° C.

Es hat sich gezeigt, dass diese Vorgaben bei herkömmlichen Kühlregalen, deren Warenvolumen mehr als 250 Liter beträgt und deren Warenräume nicht durch Türen oder Nachtrollos verschließbar sind, nicht erreicht werden können.It has been found that these specifications can not be achieved with conventional refrigerated shelves whose volume of goods is more than 250 liters and whose goods spaces can not be closed by doors or night blinds.

Aufgabe der vorliegenden Erfindung ist es, ein gattungsgemäßes Kühlregal anzugeben, das die vorgenannten Vorgaben erfüllen kann.Object of the present invention is to provide a generic cooling rack that can meet the above requirements.

Zur Lösung dieser Aufgabe wird ein Kühlregal vorgeschlagen, das dadurch gekennzeichnet ist, dass

  1. a) die Warenpräsentationsböden luftdicht mit der Warenraumrückwand verbunden sind, und
  2. b) die Mittel zum Stabilisieren des entlang der Warenraumöffnung strömenden Kühlluftschleiers derart ausgebildet sind, dass der Kühltuftschleier in Richtung des Warenraumes umgelenkt wird.
To solve this problem, a cooling rack is proposed, which is characterized in that
  1. a) the goods presentation trays are airtight connected to the goods room rear wall, and
  2. b) the means for stabilizing the flowing along the goods space opening cooling air curtain are designed such that the Kühltuftschleier is deflected in the direction of the goods space.

Das erfindungsgemäße Kühlregal, sowie weitere Ausgestaltungen desselben seien nachfolgend anhand der in den Figuren 1 bis 3 dargestellten Ausführungsbeispiele näher erläutert. Hierbei zeigen die Figuren schematisierte, seitliche Schnittdarstellungen durch mögliche Ausführungsformen des erfindungsgemäßen Kühlregales.The cooling rack according to the invention, as well as further embodiments thereof are described below with reference to the in the FIGS. 1 to 3 illustrated embodiments explained in more detail. The figures show schematic, lateral Sectional views of possible embodiments of the cooling rack according to the invention.

Die Figur 1 zeigt eine seitliche Schnittdarstellung durch ein Kühlregal 1, dessen isolierter Grundkörper, der den gekühlten Warenraum umgibt, auf einem Sockel 4 ruht. In dem gekühlten Warenraum 2 sind üblicherweise mehrere Warenpräsentationsböden 3 angeordnet.The FIG. 1 shows a side sectional view through a cooling rack 1, the isolated base body, which surrounds the refrigerated goods space, resting on a base 4. In the refrigerated goods space 2 usually several merchandise display shelves 3 are arranged.

Im Regelfall unterhalb des untersten Warenpräsentationsbodens sind die für die Erzeugung des bzw. der Kühlluftströme erforderlichen Aggregate 5 angeordnet; in der Figur 1 sind der Übersichtlichkeit halber lediglich ein Ventilator sowie ein Verdampfer dargestellt.As a rule, below the lowest goods presentation floor, the units 5 required for the generation of the cooling air flow or streams are arranged; in the FIG. 1 For the sake of clarity, only one fan and one evaporator are shown.

Der über eine im vorderen, unteren Bereich des Kühlregales angeordnete Öffnung eintretende Kühlluftschleier wird mittels des Ventilators durch den Verdampfer geführt und in diesem abgekühlt. Anschließend wird der Kühlluftstrom über den Zuluftkanal 15 zu der im vorderen, oberen Bereich des Kühlregales angeordneten Luftaustrittswabe sowie über die zumindest teilweise perforiert ausgebildete Warenraumrückwand 6 den einzelnen Warenpräsentationsböden 3 geführt. Oftmals werden - wie auch bei dem in der Figur 1 dargestellten Kühlregal gezeigt - zwei Zuluftkanäle 15 und 15' vorgesehen, wobei jedoch lediglich aus einem Zuluftkanal 15 Kühlluft durch die Warenraumrückwand 6 in den Warenraum 2 eintritt. Ein wie in der Figur 1 dargestelltes Kühlregal ist beispielsweise auch der Figur der erwähnten deutschen Patentanmeldung 103 38 672 zu entnehmen.The cooling air curtain entering via an opening arranged in the front, lower region of the cooling rack is guided by the ventilator through the evaporator and cooled therein. Subsequently, the cooling air flow over the supply air duct 15 to the arranged in the front, upper region of the cooling rack air outlet honeycomb and the at least partially perforated formed goods back wall 6 the individual goods presentation floors 3. Often - as well as in the FIG. 1 shown cooling - two supply air ducts 15 and 15 'are provided, but only from a supply air duct 15 cooling air enters through the goods room rear wall 6 in the goods compartment 2. A like in the FIG. 1 Illustrated cooling rack is, for example, the figure of the mentioned German patent application 103 38 672 refer to.

Die Figur 1a zeigt einen vergrößerten Ausschnitt der Figur 1. Dargestellt ist der "Übergangsbereich" zwischen dem durch Warenraumrückwand 6 begrenzten Zuluftkanal 15 sowie einem Warenpräsentationsboden 3. Erfindungsgemäß sind die Warenpräsentationsböden 3 nunmehr luftdicht mit der Warenraumrückwand 6 verbunden.The FIG. 1a shows an enlarged section of the FIG. 1 , Shown is the "transition area" between the limited by the goods room rear wall 6 supply air duct 15 and a goods presentation floor 3. According to the goods display shelves 3 are now airtight connected to the goods room rear wall 6.

Dies wird beispielsweise - wie in der Figur 1 a dargestellt - dadurch erreicht, dass zwei Dichtlippen 7a und 7b vorgesehen werden; diese verhindern zuverlässig das Austreten von aus dem Zuluftkanal 15 strömender Kühlluft in den gekühlten Warenraum 2. Mittels der Dichtlippen 7a und 7b wird sichergestellt, dass der gesamte Teilstrom der Kühlluft, der aus dem Zuluftkanal 15 in den Warenpräsentationsboden 3 abgelenkt wird, auch in diesen gelangt.This becomes for example - as in the FIG. 1 a - achieved by providing two sealing lips 7a and 7b; these reliably prevent the escape of cooling air flowing out of the supply air duct 15 into the cooled goods compartment 2. The sealing lips 7a and 7b ensure that the entire partial flow of the cooling air, which is deflected from the supply air duct 15 in the goods presentation floor 3, also passes into this.

Alternativ zu den vorbeschriebenen Dichtlippen 7a und 7b können beliebige flexible Dichtelemente, wie beispielsweise Klebe-Dichtbänder, zur Anwendung kommen.As an alternative to the above-described sealing lips 7a and 7b, any flexible sealing elements, such as, for example, adhesive sealing strips, can be used.

Das erfindungsgemäße Kühlregal weiterbildend wird vorgeschlagen, dass im Bereich der luftdichten Verbindung zwischen Warenraumrückwand und Warenpräsentationsboden auf der dem Zuluftkanal zugewandten Seite der Warenraumrückwand eine Umlenkvorrichtung .angeordnet ist.Further developing the refrigerated shelf according to the invention, it is proposed that a deflecting device be arranged in the region of the airtight connection between the goods space rear wall and goods presentation floor on the side of the goods space rear wall facing the supply air duct.

Wie in der Figur 1b - die wiederum eine Vergrößerung des in der Figur 1 a gezeigten Ausschnittes darstellt - gezeigt, kann die vorbeschriebene Umlenkvorrichtung beispielsweise als ein Umlenkblech 8 ausgebildet sein. Das Umlenkblech 8 dient der Optimierung der Geschwindigkeit des aus dem Zuluftkanal 15 durch die zumindest teilweise perforiert ausgebildete Warenraumrückwand 6 in den Warenpräsentationsboden 3 eintretenden Kühlluftstromes - dargestellt durch die Pfeile 13 - sowie des durch die Warenraumrückwand 6 in den hinteren Bereich des Warenraumes 2 eintretenden Kühlluftstromes - dargestellt durch die Pfeile 14.Like in the FIG. 1b - in turn, an increase in the FIG. 1 a shown section represents - shown, the above-described deflection can be formed, for example, as a baffle 8. The baffle 8 is used to optimize the speed of the incoming air duct 15 through the at least partially perforated formed goods room back wall 6 in the goods presentation floor 3 entering cooling air flow - represented by the arrows 13 - and entering through the goods room rear wall 6 in the rear of the goods compartment 2 cooling air flow - represented by the arrows 14.

Vorzugsweise ist die Umlenkvorrichtung 8 derart ausgebildet, dass der aus dem Zuluftkanal 15 in den Warenpräsentationsboden 3 eintretende Kühlluftstrom 13 eine Geschwindigkeitserhöhung auf ca. 0,7 bis 1 m/s erfährt, während der aus dem Zuluftkanal 15 in den hinteren Bereich des Warenraumes 2 eintretende Kühlluftstrom 14 eine Geschwindigkeitsreduzierung auf ca. 0,1 bis 0,5 m/s erfährt.Preferably, the deflection device 8 is designed such that the cooling air flow 13 entering from the supply air channel 15 into the goods presentation base 3 experiences an increase in speed to about 0.7 to 1 m / s, while the air entering from the supply air channel 15 enters the rear region of the goods compartment 2 Cooling air flow 14 experiences a speed reduction to about 0.1 to 0.5 m / s.

Mittels unterschiedlicher Umlenkvorrichtungen 8 können eine Vielzahl von Variationen bzgl. der Mengenverteilung der Kühlluftströme 13 und 14 sowie deren Geschwindigkeiten realisiert werden.By means of different deflection devices 8, a plurality of variations with respect to the quantity distribution of the cooling air streams 13 and 14 and their speeds can be realized.

In der Figur 1c dargestellt ist eine Ausgestaltung der erfindungsgemäßen Mittel zum Stabilisieren des entlang der Warenraumöffnung strömenden Kühlluftschleiers, wobei die vorgenannten Mittel derart ausgebildet sind, dass der Kühlluftschleier in Richtung des Warenraumes 2 umgelenkt wird.In the Figure 1c 1 shows an embodiment of the means according to the invention for stabilizing the cooling air curtain flowing along the goods space opening, wherein the aforementioned means are designed such that the cooling air curtain is deflected in the direction of the goods space 2.

Dies kann - wie in der Figur 1 c dargestellt - beispielsweise dadurch realisiert werden, dass unterhalb einer vor dem Warenpräsentationsboden 3 angeordneten Preisschiene 9 ein Umlenkblech 10 derart angeordnet ist, dass ein Luftströmungskanal 11 gebildet wird, der den von oben in den Strömungskanal 11 eintretenden Kühlluftstrom in Richtung des gekühlten Warenraumes 2 umlenkt.This can - as in the Figure 1 c shown - be realized, for example, that below a arranged in front of the goods display floor 3 price rail 9, a baffle 10 is arranged such that an air flow channel 11 is formed, which deflects the entering from above into the flow channel 11 cooling air flow in the direction of the cooled goods compartment 2.

Die damit erzielten Vorteile seien anhand der Figuren 2 und 3 näher erläutert.The advantages achieved are based on the FIGS. 2 and 3 explained in more detail.

Hierbei zeigt die Figur 2 eine Lösung, wie sie beispielsweise in der eingangs erwähnten deutschen Patentanmeldung 103 38 672 beschrieben ist. Der entlang der Warenraumöffnung strömende Kühlluftstrom bzw. -schleier wird hierbei lediglich durch die vor dem Warenpräsentationsboden 3 angeordnete Preisschiene 9' stabilisiert. Dies hat zur Folge, dass die oberste der beiden Getränkedosen 12 und 12' nur teilweise von dem Kühlluftstrom umspült wird.This shows the FIG. 2 a solution, as described for example in the aforementioned German patent application 103 38 672 is described. The cooling air flow or veil flowing along the goods space opening is hereby stabilized merely by the price rail 9 'arranged in front of the goods presentation floor 3. This has the consequence that the top of the two beverage cans 12 and 12 'is only partially washed by the cooling air flow.

Bei der in der Figur 3 dargestellten erfindungsgemäßen Lösung wird der entlang der Warenraumöffnung strömende Kühlluftstrom nunmehr durch das Umlenkblech 10 bzw. den Luftkanal 11 in Richtung des gekühlten Warenraumes 2 und damit in Richtung der obersten Getränkedose 12' abgelenkt. Somit wird auch die Getränkedose 12' optimal von dem Kühlluftstrom umspült. Dies hat zur Folge, dass die Getränkedose 12' nach einer vorgegebenen Abkühlzeit im Falle der in der Figur 3 dargestellten erfindungsgemäßen Lösung eine niedrigere Temperatur aufweist als die Getränkedose 12', die der anhand der Figur 2 erläuterten Lösung unterworfen wird.When in the FIG. 3 illustrated solution of the invention along the goods space opening flowing cooling air flow is now deflected by the baffle 10 and the air duct 11 in the direction of the refrigerated goods space 2 and thus in the direction of the uppermost beverage can 12 '. Thus, the beverage can 12 'is also lapped optimally by the cooling air flow. This has the consequence that the beverage can 12 'after a predetermined cooling time in the case of in the FIG. 3 illustrated solution according to the invention has a lower temperature than the beverage can 12 ', the basis of the FIG. 2 subjected to explained solution.

Das erfindungsgemäße Kühlregal ermöglicht zum einen einen gezielten Abgriff eines Teilstromes des Kühlluftstromes aus dem rückwärtigen Zuluftkanal 15 in die Warenpräsentationsböden 3, was eine optimierte Verteilung der Kühlluftmenge zur Folge hat; zum anderen wird durch die gezielte Umlenkung zumindest eines Teilstromes des entlang der Warenraumöffnung strömenden Kühlluftschleiers eine bessere Kühlwirkung der im vorderen, dem Kunden zugewandten Bereich eines Warenpräsentationsbodens 3 angeordneten Waren erreicht.The cooling rack according to the invention enables on the one hand a targeted tap of a partial flow of the cooling air flow from the rear supply air duct 15 in the goods presentation trays 3, which has an optimized distribution of the amount of cooling air result; On the other hand, the targeted deflection of at least one partial flow of the cooling air curtain flowing along the goods space opening achieves a better cooling effect of the goods arranged in the front, customer facing area of a goods presentation floor 3.
