Description

Die Erfindung betrifft ein zumindest teilweise gekühltes, nach vome 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.The invention relates to an at least partially cooled, after open open shelf, in which the cooling of the shelf space is effected by means of a at least partially perforated goods room back wall in the goods space flowing 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 more goods display shelves are arranged.

Die Erfindung betrifft femer ein Verfahren zum Betreiben eines zumindest teilweise gekühlten, nach vome offenen Regales.The invention further relates to a method for operating an at least partially cooled, after open open shelf.

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 sind jedoch zum einen teurer als Kühlregale ohne derartige Türen und zum anderen weniger bedienungsfreundlich, da der Zugriff auf die in ihnen präsentierten Waren erst nach dem Öffnen wenigstens einer Tür möglich ist.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 refrigerators are more expensive than refrigerated shelves without such doors and on the other hand less user-friendly, since the access to the goods presented in them only after opening at least one door is possible.

In der jüngeren Vergangenheit werden aufgrund einer geänderten Hackfleischverordnung zunehmend Hackfleischprodukte in offenen Kühlregalen präsentiert. Gemäß der vorgenannten Hackfleischverordnung ist dies jedoch nur dann erlaubt, wenn die Warenkerntemperatur zwischen -1 und +2 °C beträgt. Diese Voraussetzung kann bisher mit herkömmlichen Kühlregalen jedoch nicht erfüllt werden.In the recent past, due to an amended minced meat regulation, minced meat products are increasingly presented in open refrigerated shelves. However, according to the abovementioned minced meat ordinance, this is only permitted if the temperature of the goods is between -1 and + 2 ° C. However, this requirement can not be met with conventional refrigerated shelves so far.

In der DE 298 19 057 wird ein gattungsgemäßes Kühlregal vorgeschlagen, das einen vitrinenartigen Einsatz aufweist. Dieser schirmt den Warenraum des vitrinenartigen Einsatzes gegenüber dem restlichen Warenraum des Kühlregales derart ab, dass in dem vitrinenartigen Einsatz bzw. in dessen Warenraum eine niedrigere, für die Präsentation von Hackfleisch ausreichend niedrige Temperatur realisiert werden kann.In the DE 298 19 057 a generic cooling rack is proposed which has a vitrinenartigen use. This shields the goods space of the vitrine-like insert from the rest of the goods compartment of the refrigerated shelf in such a way that in the showcase-like use or in the goods space a lower, for the presentation of minced meat sufficiently low temperature can be realized.

Es ist jedoch offensichtlich, dass auch die Verwendung eines derartigen Einsatzes Nachteile, wie zusätzliche Kosten, Nachteile für den Kunden, etc., mit sich bringt.However, it is obvious that the use of such an insert also entails disadvantages such as additional costs, disadvantages for the customer, etc.

Aus der DE 201 19 347 ist ein gattungsgemäßes Kühleregal bekannt, bei dem über die Auslage- bzw. Warenpräsentationsböden dem vorderen Bereich der Warenpräsentationsböden Kühlluft zugeführt und über entsprechende Kühlluftaustrittsöffnungen die Warenpräsentationsböden verlässt. Diese Zuführung von Kühlluft über entsprechend ausgestaltete Warenpräsentationsböden dient insbesondere dazu, den entlang der Warenraumöffnung strömenden Kühlluftschleier zu stabilisieren. Mit dem vorgenannten Zitat sei der Offenbarungsgehalt der DE 291 19 347 in den Offenbarungsgehalt der vorliegenden Schutzrechtsanmeldung aufgenommen.From the DE 201 19 347 is a generic Kühleregal known in which supplied via the display or Warenpräsentationsböden the front portion of the goods presentation floors cooling air and leaves the product presentation floors through corresponding cooling air outlet openings. This supply of cooling air via appropriately designed merchandise display floors serves, in particular, to stabilize the cooling air curtain flowing along the goods space opening. With the above quote, the disclosure of the DE 291 19 347 included in the disclosure of the present application.

US 3,063,256 zeigt ein nach vorne offenes Kühlregal mit darin angebrachten Regalböden, das eine Reihe von Kühlluftkanälen aufweist, die außerhalb des Regales verlaufen und an der Vorderseite nach unten gerichtete Auslassöffnungen haben. Weiterhin weist das Regal in jedem der Regalböden einen Kaltluftversorgungskanal und einen Rücksaugkanal auf, wobei die Versorgungskanäle in Auslassöffnungen in der Nähe der Vorderseite des Regales enden und die Rücksaugkanäle in Aufnahmeöffnungen in der Nähe der Vorderseite des Regales enden, um kalte Luft aufzunehmen, die von den Auslassöffnungen der Versorgungskanäle ausgegeben worden ist. Das Regal weist auch Mittel auf, um kalte Luft durch den Hauptkanal und die Versorgungskanäle zu drücken und diese Luft durch Ansaugen durch die Rücksaugkanäle zurückzuführen. US 3,063,256 shows a front open cooling shelf with shelves mounted therein, which has a series of cooling air ducts that run outside the shelf and have at the front downwardly directed outlet openings. Furthermore, the shelf in each of the shelves has a cold air supply duct and a return duct, the supply ducts terminating in outlet openings near the front of the shelf and the return ducts terminating in receiving openings near the front of the shelf to receive cold air coming from the shelves Outlet openings of the supply channels has been issued. The shelf also includes means for forcing cold air through the main channel and the supply channels and returning this air by suction through the return suction channels.

Aufgabe der vorliegenden Erfindung ist es, ein gattungsgemäßes Kühlregal anzugeben, das die vorgenannten Nachteile vermeidet, insbesondere für die Präsentation von Hackfleischprodukten geeignet ist, ohne dass es hier zu einer Abschattung des Warenraumes bzw. eines Teilbereiches davon, gegen die wärmere Umgebung mittels Türen bedarf.Object of the present invention is to provide a generic cooling rack, which avoids the aforementioned disadvantages, is particularly suitable for the presentation of minced meat products, without the need for shadowing the goods space or a portion thereof, against the warmer environment by means of doors.

Ferner liegt der Erfindung die Aufgabe zugrunde, ein gattungsgemäßes Verfahren zum Betreiben eines zumindest teilweise gekühlten, nach vorne offenen Regales anzugeben, das zum einen ebenfalls die vorgenannten Nachteile vermeidet und darüber hinaus einen flexiblen Betrieb des zumindest teilweise gekühlten, nach vome offenen Regales ermöglicht.Furthermore, the invention has for its object to provide a generic method for operating an at least partially cooled, open-front shelf, which also avoids the aforementioned disadvantages and also In addition, a flexible operation of at least partially cooled, after vome open shelf allows.

Zur Lösung der erstgenannten Aufgabe wird ein Kühlregal vorgeschlagen, wobei
die Warenpräsentationsböden derart ausgebildet sind, dass über sie zumindest ein Teilstrom des Kühlluftschleiers in den Bereich der Vorderfront der Warenpräsentationsböden geführt wird, dadurch gekennzeichnet, dass

  1. a) die Warenpräsentationsböden Luftlenkkanäle (10), die im Bereich der Vorderfront der Warenpräsentationsböden (9) angeordnet sind, zum Stabilisieren des entlang der Warenraumöffnung strömenden Kühlluftschleiers aufweisen, und
  2. b) das Regal dazu ausgelegt ist, dass die Verteilung der Gesamtkühlluftstrommenge auf die über die einzelnen Warenpräsentationsböden strömenden Kühlluftschleier (11) und den entlang der Warenraumöffnung strömenden Kühlluftschleier (13) geregelt werden kann.
To solve the first object, a cooling rack is proposed, wherein
the goods presentation trays are designed such that at least a partial flow of the cooling air curtain is guided over them in the region of the front of the goods presentation trays, characterized in that
  1. a) the goods display shelves air steering channels (10) which are arranged in the region of the front of the goods display shelves (9), for stabilizing the flowing along the goods space opening cooling air curtain, and
  2. b) the shelf is designed so that the distribution of the total amount of cooling air flow can be regulated to the cooling air curtain (11) flowing over the individual goods presentation floors and the cooling air curtain (13) flowing along the goods space opening.

Das erfindungsgemäße Verfahren zum Betreiben eines zumindest teilweise gekühlten, nach vorne offenen Regales ist dadurch gekennzeichnet, dass die Verteilung der Gesamtkühlluftstrommenge auf die über die einzelnen Warenpräsentationsböden strömenden Kühlluftschleier und den entlang der Warenraumöffnung strömenden Kühlluftschleier geregelt wird.The method according to the invention for operating an at least partially cooled, open-front shelf is characterized in that the distribution of the total amount of cooling air flow is regulated to the cooling air veils flowing over the individual goods presentation bottoms and the cooling air veils flowing along the goods space opening.

Warenpräsentationsböden, die derart ausgebildet sind, dass über sie zumindest ein Teilstrom des Kühlluftschleiers in den Bereich der Vorderfront der Warenpräsentationsböden geführt werden kann, sind beispielsweise aus der vorerwähnten DE 201 19 347 bekannt. In diesem Dokument sind darüber hinaus unterschiedliche Ausführungsformen derartiger Warenpräsentationsböden sowie Vorrichtungen, mittels derer aus dem Zuluftkanal des Kühlregales ein Teilstrom des Kühlluftstromes abgezweigt und den Warenpräsentationsböden zugeführt wird, offenbart.Warenpräsentationsböden, which are designed such that at least a partial flow of the cooling air curtain can be performed in the area of the front of the goods display shelves on them, for example, from the aforementioned DE 201 19 347 known. In this document, moreover, different embodiments of such goods display shelves and devices, by means of which a partial flow of the cooling air flow is diverted from the supply air duct of the refrigerated shelf and the goods presentation shelves is supplied, disclosed.

Das erfindungsgemäße Kühlregal, das erfindungsgemäße Verfahren zum Betreiben eines zumindest teilweise gekühlten, nach vorne offenen Regales sowie weitere Ausgestaltungen desselben seien nachfolgend anhand des in der Figur dargestellten Ausführungsbeispieles näher erläutert. Hierbei zeigt die Figur eine schematisierte, seitliche Schnittdarstellung durch eine mögliche Ausführungsform des erfindungsgemäßen Kühlregales.The cooling shelf according to the invention, the inventive method for operating an at least partially cooled, open to the front shelf and Further embodiments thereof are explained in more detail below with reference to the embodiment shown in the figure. In this case, the figure shows a schematic, lateral sectional view through a possible embodiment of the cooling rack according to the invention.

Gattungsgemäße Kühlregale weisen einen isolierten Grundkörper 1, der den gekühlten Warenraum 8 umgibt, auf. Im Regelfall unterhalb des untersten Warenpräsentationsbodens 2 sind die für die Erzeugung des bzw. der Kühlluftströme erforderlichen Aggregate angeordnet; in der Figur sind der Übersichtlichkeit halber lediglich ein Ventilator 3 sowie ein Verdampfer 4 dargestellt.Generic refrigerated shelves have an isolated base body 1, which surrounds the refrigerated goods space 8 on. As a rule, below the lowest Warenpräsentationsbodens 2 are arranged for the generation of the cooling air or the required units; in the figure, for clarity, only a fan 3 and an evaporator 4 are shown.

Der über eine im vorderen, unteren Bereich des Kühlregales angeordnete Öffnung 5 eintretende Kühlluftschleier wird mittels des Ventilators 3 durch den Verdampfer 4 geführt und in diesem abgekühlt. Anschließend wird der Kühlluftstrom über den Zuluftkanal 6 zu der im vorderen, oberen Bereich des Kühlregales angeordneten Luftaustrittswabe 7 sowie den einzelnen Warenpräsentationsböden 9 geführt.The cooling air curtain entering via an opening 5 arranged in the front, lower region of the cooling rack is guided by the ventilator 3 through the evaporator 4 and cooled therein. Subsequently, the cooling air flow is guided via the supply air duct 6 to the arranged in the front, upper region of the refrigerated shelf air outlet honeycomb 7 and the individual goods display shelves 9.

Erfindungsgemäß weisen die Warenpräsentationsböden 9, die dergestalt ausgebildet sind, dass über sie zumindest ein Teilstrom des Kühlluftschleiers 11 in den Bereich der Vorderfront der Warenpräsentationsböden 9 geführt wird, femer Mittel zum Stabilisieren des entlang der Warenraumöffnung strömenden Kühlluftschleiers auf. Diese Mittel zum Stabilisieren des entlang der Warenraumöffnung strömenden Kühlluftschleiers sind vorzugsweise - wie in der Figur dargestellt - als Luftlenkkanäle 10, die im Bereich der Vorderfront der Warenpräsentationsböden 9, angeordnet sind, ausgebildet. Derartige Luftlenkkanäle 10 können beispielsweise dadurch gebildet werden, dass in einem ggf. variierbaren Abstand zu der Vorderfront jedes Warenpräsentationsbodens 9 ein wie in der Figur gezeigtes Luftleitblech angeordnet ist.According to the invention, the goods presentation trays 9, which are designed in such a way that at least a partial flow of the cooling air curtain 11 is guided into the area of the front of the goods presentation trays 9, furthermore have means for stabilizing the cooling air curtain flowing along the goods space opening. These means for stabilizing the cooling air curtain flowing along the goods space opening are preferably-as shown in the figure-designed as air-steering channels 10 which are arranged in the region of the front of the goods display shelves 9. Such air-guiding channels 10 can be formed, for example, by arranging an air guide plate as shown in the FIGURE in a possibly variable distance from the front of each goods presentation floor 9.

Erfindungsgemäß wird nunmehr im Bereich jedes Warenpräsentationsbodens 9 ein wenigstens dreilagiger Kühlluftschleier gebildet - in der Figur dargestellt durch die einzelnen Kühlluftschleier(lagen) 11, 12 und 13. Dieser kann im Hinblick auf "Störungen" - wie beispielsweise Eingriffe durch Kunden in den gekühlten Warenraum 8 -als sehr stabil angesehen werden. Zusätzlich erfolgt im Bereich des jeweils darunter liegenden Warenpräsentationsbodens 9 ein erneuter Aufbau des zumindest dreilagigen Kühlluftschleiers 11, 12 und 13.According to the invention, an at least three-layer cooling air curtain is now formed in the region of each goods presentation floor 9 - represented in the figure by the individual cooling air curtains 11, 12 and 13. With regard to "disturbances" - such as interventions by customers in the cooled goods space 8 - be regarded as very stable. In addition, in the area of the respectively underlying goods presentation floor 9, a new construction of the at least three-layer cooling air curtain 11, 12 and 13 takes place.

Dadurch, dass die Warenpräsentationsböden 9 derart ausgebildet sind, dass über sie zumindest ein Teilstrom des Kühlluftschleiers 11 geführt wird, wird zudem eine intensive Kontaktkühlung des jeweiligen Warenpräsentationsbodens 9 erreicht, wodurch wiederum die auf ihm präsentierten Produkte besser gekühlt werden.Characterized in that the goods presentation trays 9 are formed such that at least a partial flow of the cooling air curtain 11 is guided over them, also an intensive contact cooling of the respective goods presentation floor 9 is achieved, which in turn the products presented on it are better cooled.

Es hat sich überraschend gezeigt, dass mittels des erfindungsgemäß gebildeten, entlang der Warenraumöffnung strömenden Kühlluftschleiers eine so gute Abschirmung des gekühlten Warenraumes 8 gegenüber der wärmeren Umgebung(sluft) realisieren lässt, dass bei ansonsten unveränderter kältetechnischer Auslegung auch die für die Präsentation von Hackfleischprodukten erforderlichen Temperaturen erreicht werden können. Dies ist damit zum ersten Mal in einem offenen Kühlregal gelungen, ohne dass es dazu einer Erhöhung der Kälteleistung oder des Vorsehens von Türen und/oder (vitrinenartigen) Einsätzen bedurfte.It has surprisingly been found that by means of the cooling air curtain flowing along the goods space opening according to the invention, such a good shielding of the cooled goods space 8 with respect to the warmer environment (sluft) can be realized, that with otherwise cold technical design also the temperatures required for the presentation of minced meat products can be achieved. This is the first time that this has been achieved in an open refrigerated cabinet, without the need for an increase in refrigeration capacity or the provision of doors and / or (showcase-type) inserts.

In bekannten Kühlregalen beträgt die geringst mögliche Temperaturdifferenz zwischen kältester und wärmster Warentemperatur 6 K; in dem erfindungsgemäßen Kühlregal konnte diese Temperaturdifferenz auf 3 K reduziert werden.In known refrigerated shelves, the lowest possible temperature difference between the coldest and warmest goods temperature is 6 K; in the refrigerator shelf according to the invention, this temperature difference could be reduced to 3 K.

Wie bereits erwähnt, kann mittels des erfindungsgemäßen Verfahrens zum Betreiben des erfindungsgemäßen Kühlregales die Verteilung der Gesamtkühlluftstrommenge auf die über die einzelnen Warenpräsentationsböden 9 strömenden Kühlluftschleier 11 und den entlang der Warenraumöffnung strömenden Kühlluftschleier 13 geregelt werden.As already mentioned, by means of the method according to the invention for operating the refrigerated shelf according to the invention, the distribution of the total amount of cooling air flow to the cooling air curtain 11 flowing over the individual goods display shelves 9 and the cooling air curtain 13 flowing along the goods space opening can be regulated.

So ist es bei einigen Anwendungsfällen beispielsweise denkbar, dass die Zuführung von Kühlluft über die Warenpräsentationsböden 9 unterbleibt oder beispielsweise nur über jeden zweiten Warenpräsentationsboden 9 eine Kühlluftzuführung erfolgt.Thus, it is conceivable in some applications, for example, that the supply of cooling air on the goods presentation shelves 9 is omitted or, for example, a cooling air supply takes place only about every second goods presentation tray 9.

Prinzipiell denkbar ist ferner, dass beispielsweise der Luftaustrittswabe 7 keine Kühlluft zugeführt wird, der entlang der Warenraumöffnung strömende Kühlluftschleier also ausschließlich durch die über die Warenpräsentationsböden 9 geführten Kühlluftschleier 11 gebildet wird.It is also conceivable, in principle, for example, that no cooling air is supplied to the air outlet honeycomb 7, ie, the cooling air curtain flowing along the goods space opening is formed exclusively by the cooling air curtain 11 guided over the goods presentation trays 9.
