Description

Die Erfindung betrifft ein Warenverkaufsregal mit einem Warenraum, in dessen oberen Bereich ein Spiegel entlang der Längsrichtung des Möbels angeordnet ist.The invention relates to a goods sales shelf with a goods space, in the upper region of which a mirror is arranged along the longitudinal direction of the furniture.

Derartige Verkaufsmöbel mit Regalaufbau weisen in der Regel mehrere übereinander angeordnete Ebenen aus Auslageböden auf. Sie können zur Lagerung und Präsentation aller Arten von Waren dienen, die zum Verkauf angeboten werden. Neben einfachen Regalen für ungekühlte Waren kennt man auch gekühlte Varianten, bei denen ein Kühlluftschleier an der Vorderseite der Regalböden aufgebaut und außerdem zusätzlich Kühlluft von der Möbelrückwand aus über die Auslageböden geführt wird. Diese werden bevorzugt in Einzelhandelsbetrieben der Lebensmittelbranche aufgestellt und enthalten häufig Milchprodukte oder andere leicht verderblichen Erzeugnisse.Such sales furniture with a shelf structure generally have several levels of display shelves arranged one above the other. They can be used to store and present all types of goods that are offered for sale. In addition to simple shelves for uncooled goods, refrigerated versions are also known, in which a cooling air curtain is built up on the front of the shelves and, in addition, cooling air is led from the back of the furniture over the display shelves. These are preferably installed in retail businesses in the food industry and often contain dairy products or other perishable products.

Um dem Kunden einen verbesserten Einblick auf die Waren zu bieten, welche auf der obersten Auslage des Warenraumes abgestellt sind, werden an Warenverkaufsregalen Spiegel angebracht. Ihrem Zweck entsprechend sind sie im allgemeinen weder vertikal noch horizontal, sondern schräg ausgerichtet. In der Regel schließen sie mit der vertikalen Rückwand einen Winkel von etwa 45° ein.In order to offer the customer an improved view of the goods that are placed on the top shelf of the goods room, mirrors are attached to the goods display shelves. In accordance with their purpose, they are generally not aligned vertically or horizontally, but at an angle. As a rule, they form an angle of approximately 45 ° with the vertical rear wall.

Vor allem bei hoher Luftfeuchtigkeit tritt häufig das Problem auf, daß Wasser auf der Spiegeloberfläche kondensiert. Durch den Niederschlag kann seine Oberfläche soweit erblinden, daß sie ihren Zweck nicht mehr erfüllen kann. Bei größeren Mengen von Kondenswasser treten sogar hygienische Probleme durch abtropfendes Wasser auf.The problem that water condenses on the surface of the mirror frequently arises, especially in high humidity. Precipitation can blind its surface to such an extent that it can no longer serve its purpose. With larger amounts of condensed water, there are even hygienic problems caused by dripping water.

Der Erfindung liegt die Aufgabe zugrunde, ein Warenverkaufsregal der eingangs genannten Art dahingehend zu verbessern, daß die Kondensation von Wasser auf der Spiegeloberfläche möglichst weitgehend vermieden wird.The invention has for its object to improve a goods sales shelf of the type mentioned in such a way that the condensation of water on the mirror surface is avoided as much as possible.

Diese Aufgabe wird durch eine Luftleitvorrichtung gelöst, durch die Luft über die Oberfläche des Spiegels geführt wird.This object is achieved by an air guiding device through which air is guided over the surface of the mirror.

Durch den Luftstrom wird ein ständiger und effektiver Wärmeaustausch zwischen Spiegeloberfläche und benachbarter Luft bewirkt. Eine nennenswerte Temperaturdifferenz zwischen Luft und Spiegel kann damit nicht auftreten. Durch den andauernden Luftaustausch wird außerdem weitgehend vermieden, daß vollständig mit Wasser gesättigte Luft längere Zeit mit der Spiegeloberfläche in Kontakt ist. Eine Kondenswasserbildung tritt damit - auch bei hoher Luftfeuchtigkeit - nicht mehr auf.The air flow causes a constant and effective heat exchange between the mirror surface and the neighboring air. A significant temperature difference between the air and the mirror cannot occur. The continuous exchange of air also largely prevents air that is completely saturated with water from being in contact with the mirror surface for a long time. This means that condensation no longer occurs - even in high humidity.

Die Vorteile der Erfindung kommen besonders deutlich bei gekühlten Varianten des Warenverkaufsregales zur Geltung. Hierbei ist es besonders günstig, wenn in Weiterbildung des Erfindungsgedankens der Warenraum durch kalte Luft gekühlt wird und ein Teil der kalten Luft durch die Luftleitvorrichtung über die Oberfläche des Spiegels geführt wird.The advantages of the invention are particularly evident in the case of cooled variants of the goods sales shelf. In this case, it is particularly advantageous if, in a further development of the inventive concept, the goods space is cooled by cold air and part of the cold air is guided over the surface of the mirror by the air guiding device.

Die in dem Warenraum gelagerten und präsentierten Waren werden durch kalte Luft gekühlt, welche von hinten nach vorne über die Auslagen geführt wird. Zu diesem Zweck weist die Rückwand des Kühlregals Luftaustrittsöffnungen auf.The goods stored and presented in the goods room are cooled by cold air, which is led from the back to the front over the displays. For this purpose, the rear wall of the cooling shelf has air outlet openings.

Im oberen Bereich des Warenraumes schließt der Spiegel zusammen mit Rückwand und Deckenfläche des Möbels einen Zwischenraum mit in etwa dreiecksförmigem Querschnitt ein. Auch in diesem Zwischenraum strömt durch die Luftaustrittsöffnungen kalte Luft aus einem Kühlluftkanal hinter der Rückwand ein und an der Rückseite und an den Rändern des Spiegels vorbei.In the upper area of the goods room, the mirror, together with the rear wall and ceiling surface of the furniture, encloses an intermediate space with an approximately triangular cross section. In this intermediate space, too, cold air flows in through the air outlet openings from a cooling air duct behind the rear wall and past the rear and the edges of the mirror.

Der Spiegel wird dadurch im allgemeinen stärker gekühlt als die Luft an seiner dem Warenraum zugewandten Oberfläche. Versuche haben gezeigt, daß allein eine Isolierung der Rückseite des Spiegels dieses Problems noch nicht bewältigt. Erst mit dem erfindungsgemäßen Strom aus kalter und damit trockener Luft, der über die Oberfläche des Spiegels streicht, wird es möglich, die Kondensatbildung wirksam zu vermeiden.As a result, the mirror is generally cooled more than the air on its surface facing the goods area. Experiments have shown that isolating the back of the mirror alone does not solve this problem. Only with the stream of cold and thus dry air according to the invention, which sweeps over the surface of the mirror, is it possible to effectively avoid the formation of condensate.

Aus dem Warenraum aufsteigende, wärmere und damit feuchtere Luft wird durch den Schleier aus kalter Luft ferngehalten. Es hat sich gezeigt, daß auf diese Weise auch unter Extrembedingungen von Außentemperatur und Luftfeuchtigkeit Kondensatbildung auf der Spiegeloberfläche praktisch vollständig vermieden werden kann.Air that rises, warms and is therefore humid is kept out of the cold air by the veil. It has been shown that condensation formation on the mirror surface can be practically completely avoided in this way even under extreme conditions of outside temperature and air humidity.

Vorteilhaft ist es, wenn der Spiegel schräg zur Horizontalen angeordnet ist und die Luftleitvorrichtung so ausgebildet ist, daß Luft von unten her tangential über die Oberfläche des Spiegels geführt wird.It is advantageous if the mirror is arranged obliquely to the horizontal and the air guiding device is designed such that air is guided tangentially from below over the surface of the mirror.

Dies kann dadurch bewirkt werden, daß die Luftleitvorrichtung so ausgebildet ist, daß Luft um den unteren Rand des Spiegels in eine im wesentlichen zur Oberfläche des Spiegels parallele Richtung umgelenkt wird.This can be achieved in that the air guiding device is designed such that air is deflected around the lower edge of the mirror in a direction essentially parallel to the surface of the mirror.

Günstig ist hierbei die Luftleitvorrichtung in der Nähe des unteren Randes des Spiegels angeordnet und aus dem Zwischenraum zwischen Spiegel und Rückwand ausströmende kalte Luft um den unteren Rand in eine im wesentlichen zur Oberfläche des Spiegels parallele Richtung umlenkt.The air guiding device is advantageously arranged in the vicinity of the lower edge of the mirror and cold air flowing out of the space between the mirror and the rear wall is deflected around the lower edge in a direction essentially parallel to the surface of the mirror.

Vorteilhaft ist es außerdem, wenn die Luftleitvorrichtung eine erste Leitfläche aufweist, welche im wesentlichen parallel zur Oberfläche des Spiegels angeordnet ist. Die erste Leitfläche dient zur Erzeugung eines laminar strömenden Schleiers an der Oberfläche des Spiegels.It is also advantageous if the air guide device has a first guide surface which is arranged essentially parallel to the surface of the mirror. The first guide surface is used to create a laminar flow veil on the surface of the mirror.

Diese wird günstigerweise durch eine zweite Leitfläche ergänzt, welche im wesentlichen senkrecht zur Oberfläche des Spiegels angeordnet ist. Die zweite Leitfläche unterstützt die Verhinderung von Turbulenzen beim Umlenken der Luft um den unteren Rand des Spiegels.This is expediently supplemented by a second guide surface which is arranged essentially perpendicular to the surface of the mirror. The second guide surface helps prevent turbulence when the air is deflected around the lower edge of the mirror.

Die beiden Leitflächen hängen vorzugsweise zusammen und erstrecken sich über die gesamte Länge des Spiegels. Sie schließen damit zusammen mit der unteren Stirnfläche des Spiegels und dem unteren Abschnitt seiner Oberfläche einen Raum ein, der als Luftkanal dient. Vorzugsweise sind unterer Rand der zweiten Leitfläche und hinterer Rand der ersten miteinander verbunden.The two guide surfaces preferably hang together and extend over the entire length of the mirror. They thus enclose, together with the lower end face of the mirror and the lower section of its surface, a space which serves as an air duct. The lower edge of the second guide surface and the rear edge of the first are preferably connected to one another.

Die Luft aus dem Zwischenraum zwischen Spiegel und Rückwand strömt in etwa vertikal nach unten. Da der Spiegel und damit im allgemeinen auch die erste Leitfläche schräg zur vertikalen angeordnet sind, empfiehlt sich zum Abgriff der am Spiegel vorbeigeführten Luft ein Strömungsteiler, welcher zwischen Spiegel und Rückwand ausströmende Luft mindestens teilweise in die Luftleitvorrichtung einleitet. Die restliche Luft strömt weiter nach unten in den Warenraum. Der Strömungsteiler besteht vorzugsweise aus einer vertikal angeordneten Fläche.The air from the space between the mirror and the rear wall flows approximately vertically downwards. Since the mirror and thus in general also the first guide surface are arranged obliquely to the vertical, a flow divider is recommended for tapping the air passed by the mirror, which at least partially introduces air flowing out between the mirror and the rear wall into the air guide device. The remaining air flows further down into the goods room. The flow divider preferably consists of a vertically arranged surface.

Wiederum ist günstig, wenn die beiden Leitflächen und der Strömungsteiler zusammenhängen und sich im wesentlichen über die gesamte Länge des Spiegels erstrecken. Dabei schließt sich der obere Rand der zweiten Leitfläche an den unteren Bereich des Strömungsteilers an.Again, it is favorable if the two guide surfaces and the flow divider are connected and extend essentially over the entire length of the mirror. The upper edge of the second guide surface adjoins the lower area of the flow divider.

Gemäß einer Weiterbildung der Erfindung ist der Spiegel an seinem unteren Rand über mehrere entlang der Längsrichtung verteilte örtliche Halter mit einer Halteschiene verbunden, welche sich im wesentlichen über die gesamte Länge des Spiegels erstreckt.According to a development of the invention, the mirror is connected at its lower edge via a plurality of local holders distributed along the longitudinal direction to a holding rail which extends essentially over the entire length of the mirror.

Mindestens zwei solcher örtlichen Halter müssen vorgesehen sein. Halteschiene und Strömungsteiler werden vorzugsweise durch dasselbe Bauteil gebildet. Die örtlichen Halter dürfen nur eine beschränkte Längsausdehnung besitzen, da an dieser Stelle keine Luft am unteren Rand des Spiegels vorbei tangential zur Oberfläche geführt werden kann. Vorzugsweise werden relativ schmale Haken verwendet.At least two such local holders must be provided. Holding rail and flow divider are preferably formed by the same component. The local holders may only have a limited longitudinal expansion, since at this point no air can be guided past the lower edge of the mirror tangentially to the surface. Relatively narrow hooks are preferably used.

Die Halteschiene sollte mittels zweier Konsolen mit einer Stellschiene verbunden ist.The holding rail should be connected to an adjusting rail by means of two brackets.

Derartige Stellschienen sind ohnehin vorhanden, um Konsolen aufzunehmen, welche die Auslageböden stützen, auf den Waren abgestellt werden. Für einen Abschnitt zwischen zwei Stellschienen werden jeweils zwei Konsolen benötigt, zwischen denen die Halteschiene verläuft. Halteschiene und Konsolen sind vorzugsweise starr miteinander verbunden, beispielsweise durch eine Schweißnaht.Such adjusting rails are present anyway to accommodate consoles that support the display shelves on which the goods are placed. For a section between two adjusting rails, two brackets are required, between which the holding rail runs. The holding rail and brackets are preferably rigidly connected to one another, for example by means of a weld seam.

Die Erfindung sowie weitere Einzelheiten der Erfindung werden im folgenden anhand eines in den Figuren schematisch dargestellten Ausführungsbeispiels, welches ein gekühltes Warenverkaufsregal betrifft, näher erläutert.

Das in Figur 1 in seiner Gesamtheit dargestellte gekühlte Warenverkaufsregal weist einen Warenraum 1 auf, in welchem Waren auf Auslageböden 17 und einer unteren Warenauslage 18 unterhalb der Umgebungstemperatur gelagert werden können. Oberhalb der obersten Auslage ist ein Spiegel 4 angeordnet, der sich vorzugsweise über die gesamte Längsausdehnung (senkrecht zur Zeichenebene von Figur 1) des Möbels erstreckt. Der Spiegel 4 ist 0° bis 50°, vorzugsweise etwa 45° gegenüber der Vertikalen geneigt und rückseitig isoliert (20). Unterhalb der unteren Warenauslage 18 befinden sich (nicht dargestellte) Einrichtungen zum Kühlen und Umwälzen von Luft. Von dort aus wird kalte Luft 3a hinter einer Rückwand 2 nach oben geführt und strömt durch Luftaustrittsöffnungen von hinten (in Figur 1 links, Pfeile 3) bzw. oben (Pfeile 3b) in den Warenraum 1 ein.The cooled goods display shelf shown in its entirety in FIG. 1 has a goods room 1, in which goods can be stored on display shelves 17 and a lower goods display 18 below the ambient temperature. A mirror 4 is arranged above the top display, which preferably extends over the entire longitudinal extent (perpendicular to the plane of the drawing in FIG. 1) of the furniture. The mirror 4 is inclined 0 ° to 50 °, preferably approximately 45 ° with respect to the vertical, and is insulated on the back (20). Below the lower goods display 18 are devices (not shown) for cooling and circulating air. From there, cold air 3a is led upwards behind a rear wall 2 and flows through air outlet openings from behind (in FIG. 1, left, arrows 3) or above (arrows 3b) into the goods area 1.

Ein Teil dieser Kühlluft gelangt in den Zwischenraum 7, der von der Rückseite des Spiegels 4, von der Rückwand 2 und einer Deckenfläche eingeschlossen wird. Dieser Teil der kalten Luft kann oberhalb (Pfeil 3c) bzw. am unteren Rand 6 (Pfeil 8) an dem Spiegel 4 vorbeiströmen.Part of this cooling air enters the intermediate space 7, which is enclosed by the rear of the mirror 4, the rear wall 2 and a ceiling surface. This part of the cold air can flow past the mirror 4 above (arrow 3c) or at the lower edge 6 (arrow 8).

Die Aufhängung des Spiegels ist am besten in den Figuren 2 und 3 zu erkennen.The suspension of the mirror can best be seen in FIGS. 2 and 3.

In Figur 2 ist die Schnittebene so gelegt, daß sie eine Stellschiene 16 durchschneidet. Die gegenüber der Stellschiene 16 etwas nach vorne (in der Zeichnung rechts) versetzte Rückwand 2 ist daher in seitlicher Ansicht dargestellt, so daß die Luftaustrittsöffnungen, durch welche kalte Luft 3 strömt, nicht sichtbar sind.In Figure 2, the cutting plane is placed so that it cuts through an adjusting rail 16. The rear wall 2 which is offset somewhat to the front (on the right in the drawing) is therefore shown in a side view, so that the air outlet openings through which cold air 3 flows are not visible.

In Figur 3 verläuft die Schnittebene zwischen zwei Konsolen. (Im Hintergrund ist eine Konsole 15 in seitlicher Ansicht erkennbar.)In Figure 3, the cutting plane runs between two brackets. (A console 15 can be seen in the background in a side view.)

Im Bereich des unteren Randes 6 des Spiegels 4 verläuft eine Halteschiene 13 im wesentlichen über die gesamte Länge (senkrecht zur Zeichenebene) des Spiegels 4. Sie ist mindestens an zwei Stellen mit jeweils einer Konsole 15 verbunden, welche in eine Stellschiene (z.B. 16) eingehängt ist. Die Halteschiene trägt nun mehrere örtliche Halter 14, von denen einer in Figur 3 in Seitenansicht dargestellt ist. Die örtlichen Halter 14 haben nur eine geringe Längsausdehnung (senkrecht zur Zeichenebene), beispielsweise 15 bis 60 mm. Im allgemeinen sind in etwa zwei bis drei Haken pro Meter Spiegellänge vorgesehen, so daß diejenigen Abschnitte, an denen der untere Rand 6 von einem örtlichen Halter 14 umfaßt wird, nur einen marginalen Anteil der Gesamtlänge des Spiegels 4 darstellen. Der größte Teil des unteren Randes 6 bleibt frei und kann durch kalte Luft 8, 8b aus dem Zwischenraum 7 angeströmt werden.In the area of the lower edge 6 of the mirror 4, a holding rail 13 extends essentially over the entire length (perpendicular to the plane of the drawing) of the mirror 4. It is connected to at least two points with a bracket 15, which is suspended in an adjusting rail (eg 16) is. The holding rail now carries several local holders 14, one of which is shown in a side view in FIG. The local holders 14 have only a small longitudinal extent (perpendicular to the plane of the drawing), for example 15 to 60 mm. In general, about two to three hooks per meter of mirror length are provided, so that those sections on which the lower edge 6 is surrounded by a local holder 14 represent only a marginal part of the total length of the mirror 4. Most of the lower edge 6 remains free and can be flowed from the space 7 by cold air 8, 8b.

Erfindungsgemäß ist für die Umlenkung von Luft aus dem Zwischenraum 7 eine Luftleitvorrichtung 5 vorgesehen. Sie umfaßt einen Strömungsteiler, der durch die Halteschiene 13 gebildet wird, eine erste Leitfläche 11 sowie eine zweite Leitfläche 12. Die Längsausdehnung der Luftleitvorrichtung 5 (senkrecht zur Zeichenebene der Figuren) entspricht im wesentlichen derjenigen des Spiegels 4.According to the invention, an air guiding device 5 is provided for the deflection of air from the intermediate space 7. It comprises a flow divider which is formed by the holding rail 13, a first guide surface 11 and a second guide surface 12. The longitudinal extent of the air guide device 5 (perpendicular to the plane of the drawing in the figures) corresponds essentially to that of the mirror 4.

Der Strömungsteiler 13 teilt den aus dem Zwischenraum 7 kommenden Luftstrom 8 in zwei Teilströme 8a und 8b auf. Der hintere Teilluftstrom 8a dient zur zusätzlichen Kühlluftversorgung des Warenraumes 1. Der im allgemeinen kleinere Teilluftstrom 8b wird durch einen Luftkanal 19 geführt, welcher durch die Luftleitvorrichtung 5 einerseits und durch den unteren Teil 6 des Spiegels 4 andererseits gebildet wird. Die Luft wird hier zunächst durch die zweite Leitfläche 12 um etwa 45° umgelenkt. Die zweite Leitfläche 12 ist senkrecht zur Spiegeloberfläche 9 angeordnet, also etwa 45° zur Vertikalen geneigt. Danach erfolgt eine weitere Umlenkung durch die zur Spiegeloberfläche 9 parallele Leitfläche 11, welche senkrecht zur zweiten Leitfläche 12 und parallel zur Spiegeloberfläche 9 steht.The flow divider 13 divides the air flow 8 coming from the intermediate space 7 into two partial flows 8a and 8b. The rear partial air flow 8a serves for additional cooling air supply to the goods area 1. The generally smaller partial air flow 8b is guided through an air duct 19 which is formed by the air guiding device 5 on the one hand and by the lower part 6 of the mirror 4 on the other hand. The air is first deflected through the second guide surface 12 by approximately 45 °. The second guide surface 12 is arranged perpendicular to the mirror surface 9, that is to say inclined at approximately 45 ° to the vertical. This is followed by a further deflection through the guide surface 11 parallel to the mirror surface 9, which is perpendicular to the second guide surface 12 and parallel to the mirror surface 9.

Die aus dem Luftkanal 19 austretende Luft weist nun eine zur Spiegeloberfläche 9 parallele Strömungsrichtung auf und überstreicht diese tangential (Pfeil 10).The air emerging from the air channel 19 now has a flow direction parallel to the mirror surface 9 and sweeps tangentially over it (arrow 10).

Die Beaufschlagung des Spiegels 4 mit kalter und damit trockener Luft aus dem Kühlluftkreislauf verhindert ein Beschlagen der Spiegeloberfläche 9.The application of cold and thus dry air from the cooling air circuit to the mirror 4 prevents fogging of the mirror surface 9.

Es sind selbstverständlich auch andere Formen einer Luftleitvorrichtung 5 denkbar. So können z.B. die beiden Leitflächen 11, 12 und möglicherweise zusätzlich der Strömungsteiler 13 ohne Kanten ineinander übergehen. Die Luftleitvorrichtung kann dabei z.B. aus einem rund gebogenen Blech bestehen.Other forms of an air guiding device 5 are of course also conceivable. For example, the two guide surfaces 11, 12 and possibly additionally the flow divider 13 merge into one another without edges. The air guiding device can e.g. consist of a round bent sheet.
