Description

Die Erfindung bezieht sich auf eine Vitrine für die Präsentation, insbesondere Verkaufspräsentation von Frischwaren, vorzugsweise frischen Back- und/oder Konditorwaren, mit einen über betätigbare Verschlußorgane, wie Türen, Klappen oder dergleichen, von außen zugänglichen, im wesentlichen kastenartigen Warenaufnahmeraum, der mindestens einen Lufteinlaß für wenigstens einen extern erzeugten gekühlten Umluftstrom sowie mindestens einen Luftauslaß zur Abführung der Umluft aus dem Warenaufnahmeraum hat und die mit wenigstens einer Licht im Warenaufnahmeraum erzeugenden Lampe ausgerüstet ist.The invention relates to a display case for the Presentation, especially sales presentation of Fresh goods, preferably fresh baked goods and / or Confectionery, with an operable closure, such as doors, flaps or the like, from the outside accessible, essentially box-like Goods receiving room that has at least one air inlet for at least one externally generated cooled circulating air stream and at least one air outlet for exhausting the circulating air from the goods receiving room and with at least one Lamp equipped with light in the goods receiving room is.

Bei Vitrinen, die einer Verkaufspräsentation dienen, kann die dem vor der Vitrine stehenden Kunden zugekehrte Vitrinenseite als Kundenseite und die gegenüberliegende Seite, an der sich das im Ladengeschäft arbeitende Bedienungspersonal aufhält, als Bedienseite bezeichnet werden. Showcases that serve a sales presentation can those facing the customer standing in front of the showcase Showcase side as customer side and the opposite Side on which the working in the shop Operators stay, referred to as the operating side become.

Der kastenartige Warenaufnahmeraum hat an der Kundenseite eine Vorderwand aus Glas, damit der Kunde die präsentierte Ware betrachten und auswählen kann.The box-like goods receiving room has on the customer side a glass front wall for the customer to present Can view and select goods.

Der Warenaufnahmeraum ist durch Zwischenböden bzw. Einlegeböden, auf denen die Waren ablegbar sind, in Fächer unterteilt. Jedes Fach ist im Bereich einer Hinterwand und damit von der Bedienseite her, durch ein jeweils zugeordnetes Verschlußorgan verschlossen. Öffnet eine Bedienungsperson ein Verschlußorgan, kann Ware aus dem geöffneten Warenfach entnommen werden. Zweckmäßiger Weise besteht auch die Hinterwand mit ihren Verschlußorganen aus transparentem Werkstoff, was der Bedienungsperson den Zugriff auf die vom Kunden ausgewählte Ware erleichtert.The goods receiving area is separated by shelves or Shelves on which the goods can be placed in compartments divided. Each compartment is in the area of a rear wall and thus from the operating side, by one associated closure member closed. Opens one Operator a closure member, can goods from the opened goods compartment can be removed. Appropriately there is also the rear wall with its locking organs transparent material, which the operator Access to the goods selected by the customer easier.

Nach der Entnahme der Ware wird das entsprechende Warenfach, und damit der Warenaufnahmeraum wieder geschlossen, so daß der Warenaufnahmeraum eine in etwa allseits geschlossene kastenartige Kammer darstellt. Das Innere des Warenaufnahmeraums wird gekühlt, um die Frische der präsentierten Ware zu erhalten. Dazu wird über einen Lufteinlaß in den Warenaufnahmeraum gekühlte Luft geblasen. Über einen Luftauslaß wird die eingeblasene gekühlte Luft wieder abgesaugt. Demzufolge stellt sich eine ständige Luftumwälzung in Form eines Umluftstromes ein. Der Umluftstrom tritt mit niedriger Anfangstemperatur in den Warenaufnahmeraum ein. Die aus dem Warenaufnahmeraum über ihren Luftauslaß abströmende Abluft hat eine gegenüber der Eintrittstemperatur höhere Temperatur, da sie sich auf ihrem Weg vom Lufteinlaß bis zum Luftauslaß erwärmt hat.After the removal of the goods, the corresponding Goods compartment, and thus the goods storage room again closed, so that the goods receiving space is approximately box-like chamber closed on all sides. The Interior of the goods receiving room is cooled to keep the freshness to receive the presented goods. To do this, use a Cooled air intake into the goods receiving room blown. The air is blown in through an air outlet cooled air is extracted again. As a result, it turns out constant air circulation in the form of a circulating air flow on. The circulating air flow occurs at a low initial temperature in the goods receiving room. The one from the Exhaust air flowing out through their air outlet has a higher one than the inlet temperature Temperature as it moves on from air intake to has heated to the air outlet.

Diese Erwärmung erfolgt zum Beispiel auf Grund eines an und für sich unerwünschten Luftaustausches bei geöffneten Verschlußorganen, weil dabei aus der Umgebung der Vitrine warme Luft in den Warenaufnahmeraum eintreten kann. Auch über die Wände des Warenaufnahmeraumes ist eine Wärmeeinleitung gegeben.This warming occurs, for example, because of one and for unwanted air exchange when open Closure organs because doing so from the area surrounding the showcase warm air can enter the goods receiving area. Also over the walls of the goods receiving room is one Given the introduction of heat.

Es gilt deshalb bei Vitrinen, das Innere des Warenaufnahmeraums auf möglichst gleichmäßiger Kühltemperatur zu halten. Die zur Erzeugung der gekühlten Luft benötigte Energie bildet einen nicht unerheblichen Kostenfaktor für den die präsentierte Ware vertreibenden Einzelhändler, der oftmals auch mehrere Vitrinen gleichzeitig einsetzt.It is therefore the case with showcases that the inside of the Goods receiving room on as evenly as possible To maintain cooling temperature. The ones used to produce the chilled Air energy is a not insignificant Cost factor for the distributor of the presented goods Retailer who often has multiple display cases starts at the same time.

Der Erfindung liegt die Aufgabe zugrunde, bei einer Vitrine die laufenden Betriebskosten, insbesondere für die Kühlung, zu senken.The invention has for its object in a Showcase the running costs, especially for the Cooling, lower.

Diese Aufgabe ist erfindungsgemäß durch die im Kennzeichen des im Patentanspruchs 1 angegebenen Merkmale gelöst. Weitere vorteilhafte Merkmale der erfindungsgemäßen Vitrine ergeben sich aus den Unteransprüchen 2 bis 16.According to the invention, this object is characterized by the of the features specified in claim 1 solved. Further advantageous features of the invention Showcase result from subclaims 2 to 16.

Bei Vitrinen der vorbezeichneten Gattung ist es üblich, Lampen zu installieren, die das Innere des Warenaufnahmeraumes hell und gleichmäßig ausleuchten, damit insbesondere die in den einzelnen Warenfächern abgelegten Waren optimal präsentiert sind.With showcases of the aforementioned type, it is common Install lamps that cover the inside of the Illuminate the goods receiving room brightly and evenly, especially those in the individual product subjects stored goods are optimally presented.

Lampen sind Wärmeerzeuger, welche durch ihre Anordnung im Warenaufnahmeraum den Bedarf an bereitzustellender Kühlleistung erhöhen.Lamps are heat generators, which are arranged in the Goods receiving room the need for to be provided Increase cooling capacity.

Sind im Warenaufnahmeraum Temperaturfühler vorhanden, die auf die externe Kühlanlage einwirken, kann eine angeforderte höhere Kühlleistung dazu führen, das insbesondere am Lufteinlaß unerwünschte Taupunktunterschreitungen, Kondenswasserbildung und sogar Eisbildung erfolgen kann. Außerdem können die transparenten Wände des Warenaufnahmeraumes beschlagen und damit undurchsichtig werden. Bei der erfindungsgemäßen Maßnahme werden diese Nachteile bei einer Vitrine vermieden, da abzufordernde Kühlleistung durch Ausschalten der Lampenwärme niedrig gehalten werden kann. Die Lampen weisen gekapselte Gehäuse auf, welche der Abführung von Abluft aus den Warenaufnahmeraum dienen. Jedes Lampengehäuse ist somit Teil eines Leitkanals, der an der Bildung des Luftauslasses beteiligt ist. Gekühlte Luft wird aus dem Warenaufnahmeraum in die Gehäuse der Lampe gesogen und nach einer Durchströmung der Gehäuse über Luftkanäle, -schächte oder dergleichen Strömungswege, die an der Ausbildung eines Luftauslasses beteiligt sind, abgeleitet. Der gesamte Luftauslaß und damit auch die ihm zugeordneten Luftkanäle -schächte und der gleichen Strömungswege, bzw. letztlich auch das Innere der gekapselten Gehäuse der Lampen, ist der Saugseite einer mit z. B. Gebläsen ausgerüsteten externen Kühlanlage zugeordnet, in der die über den gesamten Luftauslaß aus dem Warenaufnahmeraum gesaugte Luft gekühlt und danach erneut dem Lufteinlaß des Warenaufnahmeraums zugeführt wird.Are there temperature sensors in the goods receiving room? can act on the external cooling system requested higher cooling capacity cause the undesirable drop below the dew point, especially at the air inlet, Condensation and even Ice formation can occur. In addition, the fogged up transparent walls of the goods receiving room and to become opaque. In the case of the invention Measure these drawbacks with a display case avoided because cooling capacity to be demanded by switching off the lamp heat can be kept low. The lamps have encapsulated housings, which the removal of Serve exhaust air from the goods receiving room. each The lamp housing is therefore part of a guide channel which is connected to the Air outlet formation is involved. Chilled air is from the goods receiving room into the housing of the lamp sucked and after a flow through the housing Air ducts, shafts or similar flow paths are involved in the formation of an air outlet, derived. The entire air outlet and therefore also that of him assigned air ducts - shafts and the same Flow paths, or ultimately the inside of the encapsulated housing of the lamps, the suction side is one with z. B. Blower-equipped external cooling system assigned in which over the entire air outlet air sucked into the goods receiving space cooled and then again fed to the air inlet of the goods receiving room becomes.

Die Lampen werden somit in vorteilhafter Weise gekühlt, so daß die bei der Umsetzung von elektrischer Energie in Licht freigesetzte Wärme am Entstehungsort noch innerhalb der Gehäuse der Lampen eleminiert, bzw. abgeführt wird. Die Lampengehäuse selbst können sich nicht mehr erwärmen, weil ständig ein Strom relativ kühler Luft aus dem Warenaufnahmeraum in die Gehäuse eintritt und durch die Gehäuse entlang der darin installierten Leuchtkörper streicht. The lamps are thus cooled in an advantageous manner that the in the implementation of electrical energy in Heat released at the point of origin is still inside the housing of the lamps is eliminated or discharged. The lamp housing itself can no longer heat up, because there is a constant flow of relatively cool air from the Goods receiving space enters the housing and through the Housing along the illuminants installed in it sweeps.

Nachteilige Wärmestrahlungen, insbesondere an direkt unter den Lampen liegende, wärmeempfindliche Ware, treten bei der erfindungsgemäßen Vitrine ebenfalls nicht mehr auf.Adverse heat radiation, especially on directly below the heat-sensitive goods lying on the lamps join the display case according to the invention also no longer.

Die Lampengehäuse bilden in sich geschlossene Strömungskanäle. In jedes Gehäuse kann gekühlte Luft aus dem Warenaufnahmeraum, also aus der Umgebung der Gehäuse, durch Öffnungen, Schlitze, Durchbrüche oder dergleichen offene Bereiche oder Fenster in einer Gehäusewand eintreten. Die offenen Bereiche können auch mit eingesetzten Sieben versehen sein oder auch mit Einstellorganen zur Eistellung ihrer Öffnungsweite ausgerüstet werden, zum Beispiel mit beweglichen Verschlußlamellen, Schiebeschlitzgittern oder dergleichen.The lamp housings are self-contained Flow channels. Cooled air can escape into any housing the goods receiving area, i.e. from the surroundings of the housing, through openings, slots, openings or the like open areas or windows in a housing wall enter. The open areas can also with inserted sieves can be provided or with Adjustment devices for setting their opening width be equipped, for example with mobile Sealing slats, sliding slot grilles or the like.

Der Einbau der Lampengehäuse in den Warenaufnahmeraum erfolgt derart, daß ein dem Luftauslaß zugeordneter Saug- oder Abluftkanal an wenigstens einer Stelle an das Innere des jeweiligen Lampengehäuses angeschlossen wird. Bei einem als langgestrecktes Hohlprofil aus Metall oder Kunststoff vorliegenden Gehäuse, welches sich unter einem Zwischenboden von Seitenwand zu Seitenwand des Warenaufnahmeraums erstrecken kann, ist die vorgenannte Stelle des Anschlusses an einen Saug- oder Abluftkanals ein Ende bzw. eine Stirnseite des Hohlprofils. Vorzugsweise sind beide Enden bzw. beide Stirnseiten jedes als durchlaufendes Hohlprofil vorliegendes Lampengehäuses an die zugeordnete Seitenwand angeschlossen, derart, daß an einen in der Seitenwand befindlichen Saug- Abluftkanal, der quer zu den aus mehreren Zwischenböden gebildeten Etagen im Warenaufnahmeraum verläuft, mehrere übereinander und etwa parallel zueinander liegende Lampengehäuse mit ihren Enden bzw. Stirnseiten luftleitend angeschlossen sind. The installation of the lamp housing in the goods receiving room takes place in such a way that a suction or exhaust air duct at least at one point to the inside of the respective lamp housing is connected. at one as an elongated hollow profile made of metal or Plastic present housing, which is under one Intermediate floor from side wall to side wall of the Can extend goods receiving space is the aforementioned Place of connection to a suction or exhaust air duct one end or an end face of the hollow profile. Both ends or both end faces are preferably each present as a continuous hollow profile lamp housing connected to the associated side wall, such that to a suction and exhaust air duct in the side wall, that is transverse to that formed from several intermediate floors Floors in the goods receiving room, several on top of each other and approximately parallel lamp housings with their ends or end faces connected in an air-conducting manner are.

Bei einen als langgestrecktes Hohlprofil vorliegendem Lampengehäuse ist der Durchbruch, über den Luft in das Lampengehäuse von außen einströmen kann, bezogen auf die Längserstreckung etwa mittig angeordnet. Sind beide Enden des langgestreckten Gehäuses an einen Luftkanal angeschlossen, der als Teil des Luftauslasses dient, entsteht im Lampengehäuse ein von der Mitte zu den jeweiligen Enden bzw. Stirnseiten hingerichteter Strom kühler Luft, die auf ihrem Weg zu den Enden des Lampengehäuses Wärme aufnimmt und letztlich abtransportiert. Die Lampe wird fortlaufend gekühlt.In the case of an elongated hollow profile Lamp housing is the breakthrough over which air enters the Lamp housing can flow in from the outside, based on the Longitudinal extension arranged approximately in the middle. Are both ends of the elongated housing to an air duct connected, which serves as part of the air outlet, arises in the lamp housing from the center to the respective ends or faces of executed current cool air on its way to the ends of the Lamp housing absorbs heat and ultimately removed. The lamp is continuously cooled.

Selbstverständlich ist es auch möglich mehrere über die Länge eines Lampengehäuses verteilt angeordnet Durchbrüche vorzusehen, durch die Luft einströmen kann. Dabei ist die Anordnung jedoch derart zu treffen, daß keine strömungstoten Bereiche im Lampengehäuse auftreten. Dies kann zum Beispiel durch unterschiedliche Weiten der Durchbrüche bewirkt werden. Sind die Durchbrüche zum Beispiel Schlitze, so kann die Schlitzbreite eines in der Mitte des Lampengehäuses befindlichen Durchbruches größer sein bzw. die Schlitzbreiten zum jeweiligen Ende des Lampengehäuses hin abnehmen.Of course, it is also possible to use more than one The length of a lamp housing arranged through openings to provide through which air can flow. Here is the Arrangement, however, to make such that none Stream-free areas in the lamp housing occur. This can, for example, by different widths of the Breakthroughs are brought about. Are the breakthroughs to Example slots, the slot width can be one in the Hole in the middle of the lamp housing is larger be or the slot widths to the respective end of the Remove the lamp housing.

In die Seitenwände der Vitrine sind die Luftkanäle, an die wiederum die in Form von Hohlprofilen vorliegenden Lampengehäuse angeschlossen sind, integriert. Jeder Luftkanal kann eine schachtartige Ausgestaltung sein, die in eine Isolierlage der Seitenwand eingelassen ist. Damit sind die Luftkanäle in die jeweilige Seitenwand aufgenommen bzw. integriert. Es ist auch möglich, als Luftleitkanal dienende Bauteile, zum Beispiel Profile, in die jeweilige Seitenwand bzw. in deren Isoliermaterial einzulassen. In the side walls of the showcase are the air channels to which again those in the form of hollow profiles Lamp housings are connected, integrated. Everyone Air duct can be a shaft-like design that is embedded in an insulating layer of the side wall. In order to are the air channels in the respective side wall recorded or integrated. It is also possible as Air duct components, for example profiles, in the respective side wall or in its insulating material involved.

Die erfindungsgemäße Vitrine weist einen schrankartigen Unterbau für den darauf stehenden Warenaufnahmeraum auf. In dem Unterbau ist die Anlage zur Erzeugung eines kühlenden Umluftstromes angeordnet, wobei der Boden des Warenaufnahmeraumes zugleich einen Deckel des Unterbaues bildet, der als Lufteinlaß und Luftauslaß des Warenaufnahmeraumes dienende Öffnungen hat. Diese Öffnungen sind Mündungen zugeordneter, unterbauseitiger Luft- Leitschächte, die der Saugseite bzw. Druckseite der Anlage zur Erzeugung eines gekühlten Umluftstromes zugeordnet sind.The display case according to the invention has a cupboard-like one Substructure for the goods receiving room on it. In the substructure is the system for generating a arranged cooling air flow, the bottom of the Goods receiving room also a cover of the substructure forms the air inlet and outlet of the Goods receiving space serving openings. This Openings are mouths assigned to the substructure Air guiding shafts on the suction side or pressure side of the Plant for generating a cooled air flow assigned.

Die Vitrine kann als Bausatz aus vorgefertigten Teilen angeliefert werden. Die Bauteile werden an Ort und Stelle zur betriebsbereiten Vitrine zusammengesetzt. Der Unterbau kann jedoch auch eine komplett mit allen Einbauten vorgefertigten Baueinheit sein, die am Aufstellungsort der Vitrine lediglich an den vorbestimmten Platz zu stellen ist. Darauf kann der gegebenen Falls auch als fertige Baueinheit bereit gestellte Warenaufnahmeraum gesetzt werden, wobei lediglich noch Verbindungen zwischen den Baueinheiten, zum Beispiel Verschraubungen, vorzunehmen sind, sowie elektrische Leitungen, zum Beispiel für die Lampen, an dafür vorgesehenen und vorbereiteten Trennstellen miteinander zu verbinden sind.The showcase can be built as a kit from prefabricated parts to be delivered. The components are in place assembled to the ready showcase. The substructure can also be a complete with all internals prefabricated unit to be at the site of the Showcase only in the predetermined place is. Thereupon the given case can also be finished Unit provided goods receiving space set are, with only connections between the Units, for example screw connections are, as well as electrical lines, for example for the Lamps, on designated and prepared Separation points are to be connected to each other.

Da der Boden des Warenaufnahmeraumes zugleich einen Deckel des Unterbaues bildet, der als Lufteinlaß und Luftauslaß dienende Öffnungen hat und die Öffnungen Mündungen zugeordneter unterbauseitiger Luftleitschächte sind, sind von vornherein optimale Maßnahmen getroffen, um über den Lufteinlaß zugeführte gekühlte Luft bei der Einströmung im Warenaufnahmeraum zu verteilen und nach der Durchströmung des Warenaufnahmeraumes daraus auch wieder abzuführen. Since the floor of the goods receiving area also has a lid of the substructure, which acts as an air inlet and air outlet has serving openings and the openings mouths assigned ventilation ducts on the substructure side are optimal measures taken from the outset to ensure that the Cooled air supplied to the air inlet when flowing in Distribute goods receiving room and after the flow of the goods receiving room from it again.

Dabei ist eine erste Öffnung für einen Lufteinlaß, in einen Bereich gelegt, der sich im Übergangsbereich zwischen dem Boden des Warenaufnahmeraumes und einer den Warenaufnahmeraum an seiner vorderen Kundenseite begrenzenden Vorderwand befindet. Die erste Öffnung geht dort in eine vorzugsweise schlitzartige Erweiterung über und erstreckt sich nahezu über die gesamte Länge des Warenaufnahmeraumes, wobei die Länge des Warenaufnahmeraumes in etwa der Vitrinenbreite entspricht.There is a first opening for an air inlet, in placed an area that is in the transition area between the floor of the goods receiving room and one of the Goods receiving room on its front customer side limiting front wall is located. The first opening goes there into a preferably slot-like extension and extends almost the entire length of the Goods receiving room, the length of the goods receiving room corresponds approximately to the showcase width.

Die über die schlitzartige Erweiterung in den Warenaufnahmeraum eintretende gekühlte Luft bildet einen nach oben in den Warenaufnahmeraum einströmenden Luftvorhang, der sich durch freie Verwirbelungen aufzweigt und im Warenaufnahmeraum verteilt. Vorderwände von Vitrinen sind zumeist schräg angestellt, das heißt, der Warenaufnahmeraum ist in seinem Bodenbereich tiefer als im oberen Kopfbereich. Dadurch bildet die über den Lufteinlaß eintretende Strömung gekühlter Luft einen Kreislauf aus der an der der Vorderwand gegenüberliegenden Hinterwand eine abwärts zum Boden gerichtete Luftbewegung bewirkt. Dort befindet sich wenigstens eine zweite Öffnung für einen Luftauslaß, und zwar ebenfalls in Schlitzform im Übergangsbereich zwischen dem Boden des Warenaufnahmeraums und der den Aufnahmeraum an seiner hinteren Bedienerseite begrenzenden Hinterwand. Auch die zweite Öffnung für den Luftauslaß erstreckt sich mit Vorteil über nahezu die gesamte Länge des Warenaufnahmeraumes und damit etwa über die Vitrinenbreite.The one about the slot-like extension in the Cooled air entering the goods receiving space forms one flowing upwards into the goods receiving area Air curtain that branches out due to free turbulence and distributed in the goods receiving room. Front walls of Showcases are usually placed at an angle, that is, the Goods receiving space is deeper in its floor area than in upper head area. This forms the over the air intake incoming flow of cooled air from a circuit the one on the rear wall opposite the front wall a downward movement of air causes. There is at least a second opening for an air outlet, also in slot form in Transitional area between the floor of the goods receiving room and the recording room on its rear operator side delimiting rear wall. The second opening for the Air outlet advantageously extends over almost the entire length of the goods receiving space and thus about the showcase width.

Zusätzlich zu der im Boden befindlichen zweiten Öffnung für einen Luftauslaß erfolgt der Luftauslaß erfindungsgemäß auch über die Gehäuse der Lampen. Somit wird ein Teil der Luft aus dem Warenaufnahmeraum über die zweite Öffnung im Bodenbereich vor der Hinterwand abgeführt und ein Teil der Luft über die Gehäuse der Lampen.In addition to the second opening in the floor for an air outlet, the air outlet takes place according to the invention also about the housing of the lamps. Thus a Part of the air from the goods receiving room through the second Opening in the floor area in front of the rear wall and part of the air through the housing of the lamps.

Um ausgewogene Strömungsverhältnisse zu erreichen, können die Öffnungen im Bodenbereich vor der Hinterwand und/oder der Vorderwand einstellbar ausgerüstet sein. Denkbar ist zum Beispiel eine Veränderung der Weite der Öffnung des Luftauslasses, beispielsweise durch Stellschieber oder dergleichen, wie sie auch bei Klima- und Lüftungsanlagen verwendet werden.To achieve balanced flow conditions, you can the openings in the floor area in front of the rear wall and / or the front wall must be adjustable. Is conceivable for example a change in the width of the opening of the Air outlet, for example through a slide valve or the same as in air conditioning and ventilation systems be used.

Der kastenartige Warenaufnahmeraum umfaßt bevorzugt eine aus Profilen, insbesondere Kunststoffprofilen, vorzugsweise Kunststoff-Hohlprofile, zusammengesetzte Rahmenkonstruktion, in deren freie Rahmenfächer die Vorderwand, die Hinterwand, die Seitenwände sowie eine obere Ablageplatte und der untere Boden eingesetzt sind. Dem Warenaufnahmeraum kann durch eine derartige lichte und offene Bauweise ein ansprechendes Äußeres gegeben werden, ohne Einbußen hinsichtlich der Festigkeit und Stabilität in Kauf nehmen zu müssen. Ein besonderer Vorteil ergibt sich auch dadurch, daß die Profile der Rahmenkonstruktion Hohlprofile sein können, die wiederum an der Bildung von Luftauslässen und an der Ableitung von Umluft in den Wirkbereich eines Luftleitschachtes zur Abführung der Umluft zumindest teilweise beteiligt sind. Es können sämtliche Profile an der Bildung von Luftauslässen beteiligt sein. Denkbar ist es jedoch auch, nur einen vorbestimmten Teil der Profile oder bestimmte Abschnitte der Profile an der Bildung des Luftauslasses zu beteiligen.The box-like goods receiving space preferably comprises one from profiles, in particular plastic profiles, preferably Plastic hollow profiles, composite frame construction, in the free frame compartments the front wall, the rear wall, the side walls and an upper one Storage plate and the bottom floor are inserted. the Goods receiving space can be through such a light and open design is given an appealing appearance, without sacrificing strength and stability to have to put up with. A special advantage results also in that the profiles of the frame construction Can be hollow profiles, which in turn contribute to the formation of Air outlets and the discharge of circulating air in the Effective area of an air duct to discharge the Circulating air are at least partially involved. It can all profiles in the formation of air outlets be involved. However, it is also conceivable, only one predetermined part of the profiles or certain sections the profiles at the formation of the air outlet participate.

Der Boden des Warenaufnahmeraumes bildet gleichzeitig einen den Unterbau oberseitig verschließenden Deckel. Der Deckel ist mit Vorteil ein doppelwandiges Plattenbauteil mit innerer Isolierlage, die Wärmeabstrahlungen der im Unterbau befindlichen Anlage zur Kühlung der Umluft in den Warenaufnahmeraum verhindert.The floor of the goods receiving area forms at the same time a lid closing the base on the top. The The lid is advantageously a double-walled plate component with inner insulation layer, the heat radiation from the Substructure for cooling the circulating air in the Goods receiving room prevented.

Die dem Warenaufnahmeraum zugekehrte Oberfläche des Deckels ist mit Vorteil wannenartig vertieft, wobei die wannenartige Vertiefung mit einer Abdeckplatte abgedeckt ist, die in einem vorbestimmten Abstand vor der Vorderwand und vor der Hinterwand, unter Ausbildung schlitzförmiger erster und zweiter Öffnungen für Lufteinlaß und Luftauslaß, endet.The surface of the Lid is advantageously deepened like a tub, the trough-like recess covered with a cover plate is at a predetermined distance from the front wall and in front of the back wall, forming slit-shaped first and second openings for air intake and Air outlet ends.

Die Anlage zur Kühlung der Luft sitzt im Unterbau etwa in der Vitrinenmitte. Sie kann jedoch auch mehr oder weniger zu den Endseiten der Vitrine hin versetzt sein. Die Luftleitschächte, die der Anlage zur Kühlung zugeordnet sind, münden in die wannenartige Vertiefung, wobei ein Trennblech vorgesehen ist, welches den unterhalb der Abdeckung befindlichen Mündungsbereich eines dem Luftauslaß zugeordneten saugseitigen Luftleitschachtes gegenüber dem Mündungsbereich eines dem Lufteinlaß zugeordneten druckseitigen Luftleitschachtes abschaltet.The system for cooling the air is located in the substructure the middle of the showcase. However, it can do more or less be offset towards the end of the showcase. The Air ducts assigned to the cooling system are, open into the trough-like recess, with a Divider is provided, which is below the Cover located mouth area of the Air outlet associated suction side air duct opposite the mouth area of an air inlet switches off the associated pressure-side air duct.

Diese Ausgestaltung hat den wesentlichen Vorteil, daß die aus dem Luftleitschacht, welcher dem Lufteinlaß zugeordnet ist, heranströmende gekühlte Luft zunächt in die wannenartige Vertiefung einströmt und nahezu über die gesamte Fläche der Abdeckung verteilt wird, bevor ein Austritt aus der wannenartigen Vertiefung über die erste schlitzartige Erweiterung der Öffnung vor der Vorderwand in den Warenaufnahmeraum einströmt. Gleichzeitig wird bei dieser Verteilung der aus dem Luftleitschacht in die wannenartige Vertiefung einströmenden gekühlten Luft die Abdeckung von unten gekühlt, so daß der Warenaufnahmeraum einen mit Vorteil ständig gekühlten Boden besitzt. This configuration has the main advantage that the from the air duct, which is assigned to the air inlet is flowing cooling air into the trough-like depression flows in and almost over the entire area of the cover is spread out before a Exit from the trough-like depression via the first slot-like expansion of the opening in front of the front wall flows into the goods receiving room. At the same time this distribution of the air duct in the trough-like depression flowing in cooled air Cover cooled from below, so that the goods receiving space has a floor that is constantly cooled.

Das Trennblech ist dabei, bezogen auf den Abstand zwischen Hinterwand und Vorderwand zur Hinterwand versetzt angeordnet, wodurch der gekühlte Bereich des Bodens des Warenaufnahmeraumes vergrößert ist. Über den schlitzförmigen Erweiterungen der ersten und zweiten Öffnungen können auch noch Leitelemente für die ein- bzw. ausströmende Luft angeordnet werden die zur Regelung und Einstellung der Luftströme herangezogen werden können und die zugleich auch als "Krümelsiebe" dienen können, welche verhindern, daß versehentlich herabfallende Teile der präsentierten Waren in die Luftleitschächte gelangen.The divider is here, based on the distance between Rear wall and front wall offset from the rear wall arranged, whereby the cooled area of the bottom of the Goods receiving room is enlarged. Over the slit-shaped Extensions to the first and second openings can also guide elements for the one or escaping air are arranged to regulate and Setting the air flows can be used and which can also serve as "crumb sieves", which prevent accidental falling parts of the presented goods get into the air ducts.
