Definitions
- the invention relates to a display case for the presentation, in particular sales presentation of fresh goods, preferably fresh baked goods and / or confectionery, with a closure member which can be actuated via doors, flaps or the like, is accessible from the outside, essentially box-like goods receiving space, with at least one air inlet for at least an externally generated cooled circulating air flow and with at least one air outlet for removing the circulating air from the goods receiving area and with at least one lamp in the goods receiving area generating light, each of which has a closed housing with at least partially translucent housing walls.
- the display case side facing the customer standing in front of the display case can be used as the customer side and the opposite side on which the person working in the shop is working Operating personnel, are referred to as the operating side.
- the box-like goods receiving room has a glass front wall on the customer side so that the customer can view and select the goods presented.
- the goods receiving area is divided into compartments by intermediate shelves or shelves on which the goods can be placed.
- Each compartment is closed in the area of a rear wall and thus from the operating side by a respectively assigned locking member. If an operator opens a closure member, goods can be removed from the open goods compartment.
- the rear wall with its locking members is also expediently made of transparent material, which makes it easier for the operator to access the goods selected by the customer.
- the goods receiving space is a box-like chamber which is closed on all sides.
- the inside of the goods receiving room is cooled to keep the freshness of the presented goods.
- cooled air is blown into the goods receiving space via an air inlet.
- the blown-in cooled air is sucked out again via an air outlet.
- the circulating air flow enters the goods receiving room at a low initial temperature.
- the exhaust air flowing out of the goods receiving space via its air outlet has a higher temperature than the inlet temperature, since it has warmed up on its way from the air inlet to the air outlet.
- This heating takes place, for example, on the basis of an inherently undesirable air exchange when the closure members are open, because warm air can enter the goods receiving area from the surroundings of the display case. Heat is also introduced over the walls of the goods receiving area.
- a display case in which incandescent lamps are arranged in a closed housing, which is designed as a channel for the forced passage of air drawn in from the surroundings of the display case.
- the air heated up by the flow of light bulbs exits into the surroundings of the showcase.
- Lamps are heat generators, which, due to their arrangement in the goods receiving area, increase the need for cooling power to be provided. This would be the case with the display case known from GB-A-2 231 140, but in particular it occurs with the display case known from DE-A-25 05 390.
- the object of the invention is to reduce the running costs, in particular for cooling, of a display case.
- a cooling capacity to be demanded is kept low by switching off the lamp heat.
- the lamps have encapsulated housings which are used to discharge exhaust air from the goods receiving area. Each lamp housing is therefore part of a guide channel that is involved in the formation of the air outlet. Cooled air is drawn from the goods receiving space into the housing of the lamp and, after it has flowed through the housing via air ducts, shafts or similar flow paths that are involved in the formation of an air outlet. The entire air outlet and so that the associated air channels, shafts and the like flow paths, or ultimately the interior of the encapsulated housing of the lamps, the suction side is one with z.
- blower equipped external cooling system in which the air sucked in over the entire air outlet from the goods receiving space is cooled and then supplied again to the air inlet of the goods receiving space.
- the lamps are thus cooled in an advantageous manner, so that the heat released during the conversion of electrical energy into light is eliminated or dissipated at the point of origin within the housing of the lamps.
- the lamp housing itself can no longer heat up because a stream of relatively cool air constantly enters the housing from the goods receiving space and sweeps through the housing along the luminous elements installed therein.
- Adverse heat radiation in particular from heat-sensitive goods lying directly under the lamps, likewise no longer occur in the display case according to the invention.
- the lamp housings form closed flow channels. Cooled air can enter each housing from the goods receiving space, that is to say from the surroundings of the housing, through openings, slots, openings or the like, open areas or windows in a housing wall.
- the open areas can also be provided with inserted sieves or can also be equipped with adjusting elements for adjusting their opening width, for example with movable closure slats, sliding slot grilles or the like.
- the lamp housing is installed in the goods receiving space in such a way that a suction or exhaust air duct assigned to the air outlet is connected to the interior of the respective lamp housing at at least one point.
- a suction or exhaust air duct assigned to the air outlet is connected to the interior of the respective lamp housing at at least one point.
- the aforementioned point of connection to a suction or exhaust air duct is one end or an end face of the hollow profile.
- both ends or both end faces of each lamp housing present as a continuous hollow profile are connected to the associated side wall, such that several are located one above the other and approximately on a suction and exhaust air duct located in the side wall, which runs transversely to the floors formed from a plurality of intermediate floors in the goods receiving space
- Lamp housings lying parallel to one another are connected with their ends or end faces in an air-conducting manner.
- the opening through which air can flow into the lamp housing from the outside is arranged approximately in the middle with respect to the longitudinal extent. If both ends of the elongated housing are connected to an air duct that serves as part of the air outlet, a flow of cool air is carried out in the lamp housing from the center to the respective ends or end faces, which absorbs heat on the way to the ends of the lamp housing and ultimately removed.
- the lamp is continuously cooled.
- the arrangement must be such that no dead zones occur in the lamp housing. This can be caused, for example, by different widths of the openings. If the openings are slots, for example, the slot width of an opening located in the center of the lamp housing can be larger or the slot widths can decrease towards the respective end of the lamp housing.
- Each air duct can be a shaft-like configuration that is embedded in an insulating layer of the side wall.
- the air ducts are thus incorporated or integrated into the respective side wall. It is also possible to insert components serving as air duct, for example profiles, in the respective side wall or in its insulating material.
- the display case according to the invention has a cupboard-like base for the goods receiving space standing on it.
- the system for generating a cooling circulating air flow is arranged, the floor of the goods receiving space also forming a cover of the substructure, which has openings serving as the air inlet and air outlet of the goods receiving space. These openings are mouths of associated air duct shafts on the substructure side, which are assigned to the suction side or pressure side of the system for generating a cooled circulating air flow.
- the showcase can be delivered as a kit made of prefabricated parts.
- the components are assembled on site to make the showcase ready for use.
- the substructure can also be a prefabricated unit complete with all internals, which is only to be placed at the predetermined location at the installation site of the display case. If necessary, goods receiving space provided as a finished unit can be placed on top of it, with only connections between the units, for example screw connections, as well as electrical lines, for example for the lamps, to be connected to one another at designated and prepared separation points ,
- the floor of the goods receiving space also forms a cover of the substructure, which has openings serving as air inlet and air outlet and the openings are mouths of associated air duct shafts on the substructure side, optimal measures are taken from the outset to distribute cooled air supplied via the air inlet when flowing into the goods receiving space and, after flowing through the goods receiving space, also to be removed therefrom.
- a first opening for an air inlet is placed in an area which is located in the transition area between the floor of the goods receiving space and a front wall delimiting the goods receiving space on its front customer side.
- the first opening there merges into a preferably slot-like extension and extends almost over the entire length of the goods receiving space, the length of the goods receiving space roughly corresponding to the width of the display case.
- the cooled air entering the goods receiving space via the slot-like extension forms an air curtain flowing upward into the goods receiving space, which branches out through free turbulence and is distributed in the goods receiving space.
- the front walls of showcases are usually set at an angle, which means that the goods storage area is lower in the floor area than in the upper head area.
- the flow of cooled air entering via the air inlet forms a circuit from the rear wall opposite the front wall, causing air to move downwards towards the floor.
- There is at least a second opening for an air outlet also in the form of a slot in the transition area between the floor of the goods receiving space and the rear wall delimiting the receiving space on its rear operator side.
- the second opening for the air outlet also extends advantageously over almost the entire length of the goods receiving space and thus approximately over the width of the display case.
- the air outlet also takes place according to the invention via the housing of the lamps. This means that part of the air from the goods receiving area passes through the second Opening in the floor area in front of the rear wall and part of the air discharged through the housing of the lamps.
- the openings in the floor area in front of the rear wall and / or the front wall can be equipped to be adjustable.
- a change in the width of the opening of the air outlet is conceivable, for example by means of adjusting slides or the like, as are also used in air conditioning and ventilation systems.
- the box-like goods receiving space preferably comprises a frame construction composed of profiles, in particular plastic profiles, preferably plastic hollow profiles, in the free frame compartments of which the front wall, the rear wall, the side walls and an upper storage plate and the lower floor are inserted.
- profiles of the frame construction can be hollow profiles, which in turn are at least partially involved in the formation of air outlets and in the diversion of circulating air into the effective area of an air duct for extracting the circulating air. All profiles can be involved in the formation of air outlets. However, it is also conceivable to involve only a predetermined part of the profiles or certain sections of the profiles in the formation of the air outlet.
- the floor of the goods receiving space also forms a cover that closes the base on the top.
- the lid is advantageously a double-walled plate component With an inner insulation layer that prevents heat radiation from the system in the substructure for cooling the circulating air into the goods receiving area.
- the surface of the cover facing the goods receiving space is advantageously recessed in a trough-like manner, the trough-like recess being covered with a cover plate which ends at a predetermined distance in front of the front wall and in front of the rear wall, forming slot-shaped first and second openings for air inlet and air outlet.
- the system for cooling the air is located in the base approximately in the middle of the display case. However, it can also be offset more or less towards the end of the display case.
- the air ducts, which are assigned to the system for cooling, open into the trough-like depression, a separating plate being provided, which shuts off the opening region below the cover of a suction-side air duct assigned to the air outlet relative to the opening region of a pressure-side air duct assigned to the air inlet.
- This embodiment has the essential advantage that the cooled air flowing in from the air duct, which is assigned to the air inlet, flows into the trough-like depression and is distributed over almost the entire surface of the cover before it exits the trough-like depression via the first slot-like depression Extension of the opening in front of the front wall flows into the goods receiving room.
- the cover is cooled from below, so that the goods receiving space advantageously has a constantly cooled floor.
- the partition plate is arranged offset with respect to the distance between the rear wall and the front wall to the rear wall, as a result of which the cooled area of the floor of the goods receiving space is enlarged.
- Over the slot-shaped extensions of the first and second openings can also be arranged guide elements for the incoming or outgoing air which can be used to regulate and adjust the air flows and which can also serve as "crumb sieves", which prevent accidental falling Parts of the goods presented reach the air ducts.

Abstract
Description
Die Erfindung bezieht sich auf eine Vitrine für die Präsentation, insbesondere Verkaufspräsentation von Frischwaren, vorzugsweise frischen Back- und/oder Konditorwaren, mit einem über Türen, Klappen oder dergleichen betätigbaren Verschlußorganen von außen zugänglichen, im wesentlichen kastenartigen Warenaufnahmeraum, mit mindestens einem Lufteinlaß für wenigstens einen extern erzeugten gekühlten Umluftstrom sowie mit mindestens einem Luftauslaß zur Abführung der Umluft aus dem Warenaufnahmeraum und mit wenigstens einer Licht im Warenaufnahmeraum erzeugenden Lampe, von der jede ein geschlossenes Gehäuse mit zumindest teilweise lichtdurchlässigen Gehäusewänden aufweist.The invention relates to a display case for the presentation, in particular sales presentation of fresh goods, preferably fresh baked goods and / or confectionery, with a closure member which can be actuated via doors, flaps or the like, is accessible from the outside, essentially box-like goods receiving space, with at least one air inlet for at least an externally generated cooled circulating air flow and with at least one air outlet for removing the circulating air from the goods receiving area and with at least one lamp in the goods receiving area generating light, each of which has a closed housing with at least partially translucent housing walls.
Eine Vitrine der vorbezeichneten Gattung ist nach der DE-A-25 05 390 bekannt.A showcase of the aforementioned type is known from DE-A-25 05 390.
Bei der bekannten Vitrine, die einer Verkaufspräsentation dient, 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.In the known display case, which serves for a sales presentation, the display case side facing the customer standing in front of the display case can be used as the customer side and the opposite side on which the person working in the shop is working Operating personnel, are referred to as the operating side.
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 a glass front wall on the customer side so that the customer can view and select the goods presented.
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 divided into compartments by intermediate shelves or shelves on which the goods can be placed. Each compartment is closed in the area of a rear wall and thus from the operating side by a respectively assigned locking member. If an operator opens a closure member, goods can be removed from the open goods compartment. The rear wall with its locking members is also expediently made of transparent material, which makes it easier for the operator to access the goods selected by the customer.
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 goods have been removed, the corresponding goods compartment, and thus the goods receiving space, is closed again, so that the goods receiving space is a box-like chamber which is closed on all sides. The inside of the goods receiving room is cooled to keep the freshness of the presented goods. For this purpose, cooled air is blown into the goods receiving space via an air inlet. The blown-in cooled air is sucked out again via an air outlet. As a result, there is constant air circulation in the form of a circulating air flow. The circulating air flow enters the goods receiving room at a low initial temperature. The exhaust air flowing out of the goods receiving space via its air outlet has a higher temperature than the inlet temperature, since it has warmed up on its way from the air inlet 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 heating takes place, for example, on the basis of an inherently undesirable air exchange when the closure members are open, because warm air can enter the goods receiving area from the surroundings of the display case. Heat is also introduced over the walls of the goods receiving area.
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.In the case of display cabinets of the aforementioned type, it is customary to install lamps which illuminate the interior of the goods receiving space brightly and uniformly, so that in particular the goods stored in the individual goods compartments are optimally presented.
Nach der GB-A-2 231 140 ist eine Vitrine bekannt, bei der Glühlampen in einem geschlossenen Gehäuse angeordnet sind, welches als Kanal zur zwangsweisen Durchführung von aus der Umgebung der Vitrine angesaugter Luft ausgebildet ist. Die durch die Vorbeiströmung an den Glühlampen erwärmte Luft tritt wieder in die Umgebung der Vitrine aus.According to GB-A-2 231 140, a display case is known in which incandescent lamps are arranged in a closed housing, which is designed as a channel for the forced passage of air drawn in from the surroundings of the display case. The air heated up by the flow of light bulbs exits into the surroundings of the showcase.
Dadurch werden unerwünschte Auswirkungen der Wärme auf den Warenaufnahmeraum im Inneren der Vitrine zwar weitgehend, jedoch nicht vollständig vermieden.As a result, undesirable effects of the heat on the goods receiving space inside the showcase are largely, but not completely avoided.
Lampen sind Wärmeerzeuger, welche durch ihre Anordnung im Warenaufnahmeraum den Bedarf an bereitzustellender Kühlleistung erhöhen. Dies wäre bei der nach der GB-A-2 231 140 bekannten Vitrine der Fall, insbesondere jedoch tritt es bei der nach der DE-A-25 05 390 bekannten Vitrine auf.Lamps are heat generators, which, due to their arrangement in the goods receiving area, increase the need for cooling power to be provided. This would be the case with the display case known from GB-A-2 231 140, but in particular it occurs with the display case known from DE-A-25 05 390.
Sind im Warenaufnahmeraum Temperaturfühler vorhanden, die auf die externe Kühlanlage einwirken, kann bei beiden bekannten Vitrinen eine angeforderte höhere Kühlleistung dazu führen, daß insbesondere am Lufteinlaß der extern gekühlten Luft in die Vitrine unerwünschte Taupunktunterschreitungen, Kondenswasserbildung und sogar Eisbildung erfolgen kann. Außerdem können die transparenten Wände des Warenaufnahmeraumes beschlagen und damit undurchsichtig werden.If there are temperature sensors in the goods receiving room that act on the external cooling system, a higher cooling capacity can be requested for both known showcases lead to undesirable drop below dew point, condensation and even ice formation, in particular at the air inlet of the externally cooled air into the display case. In addition, the transparent walls of the goods receiving room can fog up and become opaque.
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.For showcases, it is therefore important to keep the interior of the goods-receiving room at a uniform cooling temperature. The energy required to generate the cooled air is a not inconsiderable cost factor for the retailer selling the goods on display, who often also uses several showcases at the same time.
Der Erfindung liegt die Aufgabe zugrunde, bei einer Vitrine die laufenden Betriebskosten, insbesondere für die Kühlung, zu senken.The object of the invention is to reduce the running costs, in particular for cooling, of a display case.
Diese Aufgabe ist erfindungsgemäß durch die im Patentanspruch 1 angegebenen Merkmale gelöst. Weitere vorteilhafte Merkmale der erfindungsgemäßen Vitrine ergeben sich aus den Unteransprüchen 2 bis 16.This object is achieved by the features specified in claim 1. Further advantageous features of the display case according to the invention result from subclaims 2 to 16.
Bei der erfindungsgemäßen Vitrine wird eine abzufordernde Kühlleistung durch Ausschalten der Lampenwärme niedrig gehalten. 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 dergleichen 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.In the display case according to the invention, a cooling capacity to be demanded is kept low by switching off the lamp heat. The lamps have encapsulated housings which are used to discharge exhaust air from the goods receiving area. Each lamp housing is therefore part of a guide channel that is involved in the formation of the air outlet. Cooled air is drawn from the goods receiving space into the housing of the lamp and, after it has flowed through the housing via air ducts, shafts or similar flow paths that are involved in the formation of an air outlet. The entire air outlet and so that the associated air channels, shafts and the like flow paths, or ultimately the interior of the encapsulated housing of the lamps, the suction side is one with z. B. blower equipped external cooling system in which the air sucked in over the entire air outlet from the goods receiving space is cooled and then supplied again to the air inlet of the goods receiving space.
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, so that the heat released during the conversion of electrical energy into light is eliminated or dissipated at the point of origin within the housing of the lamps. The lamp housing itself can no longer heat up because a stream of relatively cool air constantly enters the housing from the goods receiving space and sweeps through the housing along the luminous elements installed therein.
Nachteilige Wärmestrahlungen, insbesondere an direkt unter den Lampen liegende, wärmeempfindliche Ware, treten bei der erfindungsgemäßen Vitrine ebenfalls nicht mehr auf.Adverse heat radiation, in particular from heat-sensitive goods lying directly under the lamps, likewise no longer occur in the display case according to the invention.
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 form closed flow channels. Cooled air can enter each housing from the goods receiving space, that is to say from the surroundings of the housing, through openings, slots, openings or the like, open areas or windows in a housing wall. The open areas can also be provided with inserted sieves or can also be equipped with adjusting elements for adjusting their opening width, for example with movable closure slats, sliding slot grilles or the like.
Der Einbau der Lampengehäuse in den Warenaufnahmeraum erfolgt derart, daß ein dem Luftauslaß zugeordneter Saugoder 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 lamp housing is installed in the goods receiving space in such a way that a suction or exhaust air duct assigned to the air outlet is connected to the interior of the respective lamp housing at at least one point. In the case of a housing which is in the form of an elongated hollow profile made of metal or plastic and which can extend under an intermediate floor from side wall to side wall of the goods receiving space, the aforementioned point of connection to a suction or exhaust air duct is one end or an end face of the hollow profile. Preferably, both ends or both end faces of each lamp housing present as a continuous hollow profile are connected to the associated side wall, such that several are located one above the other and approximately on a suction and exhaust air duct located in the side wall, which runs transversely to the floors formed from a plurality of intermediate floors in the goods receiving space Lamp housings lying parallel to one another are connected with their ends or end faces in an air-conducting manner.
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 a lamp housing in the form of an elongated hollow profile, the opening through which air can flow into the lamp housing from the outside is arranged approximately in the middle with respect to the longitudinal extent. If both ends of the elongated housing are connected to an air duct that serves as part of the air outlet, a flow of cool air is carried out in the lamp housing from the center to the respective ends or end faces, which absorbs heat on the way to the ends of the lamp housing 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 provide a plurality of openings which are distributed over the length of a lamp housing and through which air can flow. However, the arrangement must be such that no dead zones occur in the lamp housing. This can be caused, for example, by different widths of the openings. If the openings are slots, for example, the slot width of an opening located in the center of the lamp housing can be larger or the slot widths can decrease towards the respective end of 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.The air channels, to which the lamp housings in the form of hollow profiles are connected, are integrated into the side walls of the showcase. Each air duct can be a shaft-like configuration that is embedded in an insulating layer of the side wall. The air ducts are thus incorporated or integrated into the respective side wall. It is also possible to insert components serving as air duct, for example profiles, in the respective side wall or in its insulating material.
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 base for the goods receiving space standing on it. In the substructure, the system for generating a cooling circulating air flow is arranged, the floor of the goods receiving space also forming a cover of the substructure, which has openings serving as the air inlet and air outlet of the goods receiving space. These openings are mouths of associated air duct shafts on the substructure side, which are assigned to the suction side or pressure side of the system for generating a cooled circulating air flow.
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 delivered as a kit made of prefabricated parts. The components are assembled on site to make the showcase ready for use. However, the substructure can also be a prefabricated unit complete with all internals, which is only to be placed at the predetermined location at the installation site of the display case. If necessary, goods receiving space provided as a finished unit can be placed on top of it, with only connections between the units, for example screw connections, as well as electrical lines, for example for the lamps, to be connected to one another at designated and prepared separation points ,
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 space also forms a cover of the substructure, which has openings serving as air inlet and air outlet and the openings are mouths of associated air duct shafts on the substructure side, optimal measures are taken from the outset to distribute cooled air supplied via the air inlet when flowing into the goods receiving space and, after flowing through the goods receiving space, also to be removed therefrom.
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.In this case, a first opening for an air inlet is placed in an area which is located in the transition area between the floor of the goods receiving space and a front wall delimiting the goods receiving space on its front customer side. The first opening there merges into a preferably slot-like extension and extends almost over the entire length of the goods receiving space, the length of the goods receiving space roughly corresponding to the width of the display case.
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 cooled air entering the goods receiving space via the slot-like extension forms an air curtain flowing upward into the goods receiving space, which branches out through free turbulence and is distributed in the goods receiving space. The front walls of showcases are usually set at an angle, which means that the goods storage area is lower in the floor area than in the upper head area. As a result, the flow of cooled air entering via the air inlet forms a circuit from the rear wall opposite the front wall, causing air to move downwards towards the floor. There is at least a second opening for an air outlet, also in the form of a slot in the transition area between the floor of the goods receiving space and the rear wall delimiting the receiving space on its rear operator side. The second opening for the air outlet also extends advantageously over almost the entire length of the goods receiving space and thus approximately over the width of the display case.
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 for an air outlet located in the floor, the air outlet also takes place according to the invention via the housing of the lamps. This means that part of the air from the goods receiving area passes through the second Opening in the floor area in front of the rear wall and part of the air discharged 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.In order to achieve balanced flow conditions, the openings in the floor area in front of the rear wall and / or the front wall can be equipped to be adjustable. For example, a change in the width of the opening of the air outlet is conceivable, for example by means of adjusting slides or the like, as are also used in air conditioning and ventilation systems.
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 a frame construction composed of profiles, in particular plastic profiles, preferably plastic hollow profiles, in the free frame compartments of which the front wall, the rear wall, the side walls and an upper storage plate and the lower floor are inserted. Such a light and open design allows the goods receiving area to be given an appealing exterior without having to accept losses in terms of strength and stability. A particular advantage also results from the fact that the profiles of the frame construction can be hollow profiles, which in turn are at least partially involved in the formation of air outlets and in the diversion of circulating air into the effective area of an air duct for extracting the circulating air. All profiles can be involved in the formation of air outlets. However, it is also conceivable to involve only a predetermined part of the profiles or certain sections of the profiles in the formation of the air outlet.
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 space also forms a cover that closes the base on the top. The lid is advantageously a double-walled plate component With an inner insulation layer that prevents heat radiation from the system in the substructure for cooling the circulating air into the goods receiving area.
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 cover facing the goods receiving space is advantageously recessed in a trough-like manner, the trough-like recess being covered with a cover plate which ends at a predetermined distance in front of the front wall and in front of the rear wall, forming slot-shaped first and second openings for air inlet and air outlet.
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 base approximately in the middle of the display case. However, it can also be offset more or less towards the end of the display case. The air ducts, which are assigned to the system for cooling, open into the trough-like depression, a separating plate being provided, which shuts off the opening region below the cover of a suction-side air duct assigned to the air outlet relative to the opening region of a pressure-side air duct assigned to the air inlet.
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 embodiment has the essential advantage that the cooled air flowing in from the air duct, which is assigned to the air inlet, flows into the trough-like depression and is distributed over almost the entire surface of the cover before it exits the trough-like depression via the first slot-like depression Extension of the opening in front of the front wall flows into the goods receiving room. At the same time, with this distribution of the cooled air flowing into the trough-like depression from the air duct, the cover is cooled from below, so that the goods receiving space advantageously has a constantly cooled floor.
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 partition plate is arranged offset with respect to the distance between the rear wall and the front wall to the rear wall, as a result of which the cooled area of the floor of the goods receiving space is enlarged. Over the slot-shaped extensions of the first and second openings can also be arranged guide elements for the incoming or outgoing air which can be used to regulate and adjust the air flows and which can also serve as "crumb sieves", which prevent accidental falling Parts of the goods presented reach the air ducts.

The showcase has a cabinet-like substructure 1 for a goods receiving space 2 above it. A system for generating a cooled circulating air flow is arranged in the substructure, the cooling generator of which is designated by 3. The cooling medium with a low temperature provided by the cooling generator 3 is sent in a circuit through a heat exchanger 4. The heat exchanger 4 sits in a chamber 5 of the base 1 of the showcase. The chamber 5 is through a partition plate 6 in sub-side, separate air ducts 7 and 8 divided. The dividing plate 6 has through-windows 9 in the lower area in which electric fans 10 are inserted.
Der Unterbau 1 ist an der Oberseite mit einem Deckel 11 verschlossen. Der Deckel 11 ist ein doppelwandiges Plattenbauteil mit innerer Isolierlage 12.The base 1 is closed at the top with a lid 11. The cover 11 is a double-walled plate component with an inner insulating layer 12.
Der Deckel 11 bildet zugleich den Boden des Warenaufnahmeraumes 2. Der Warenaufnahmeraum 2 ist kastenartig ausgebildet und umfaßt eine aus Profilen 13, 13', 13'' und 13''' zusammengesetzte Rahmenkonstruktion, in deren freie Rahmenfächer eine Vorderwand, eine Hinterwand 15, Seitenwände 16 bzw. 16' sowie eine obere Ablageplatte 17 und der untere Boden, der zugleich ein Deckel 11 des Unterbaues 1 ist, eingesetzt sind.The lid 11 also forms the bottom of the goods receiving space 2. The goods receiving space 2 is box-shaped and comprises a frame construction composed of profiles 13, 13 ', 13' 'and 13' '', in the free frame compartments of a front wall, a rear wall 15, side walls 16 and 16 'and an upper shelf 17 and the lower floor, which is also a lid 11 of the base 1, are used.
Die Vorderwand 14 befindet sich an der Kundenseite der Vitrine. Die Hinterwand 15 an der Bedienseite der Vitrine.The front wall 14 is located on the customer side of the display case. The rear wall 15 on the operating side of the display case.
Die Vorderwand 14 wird durch eine Glasscheibe gebildet, die mit ihrem unteren Rand klappbar am rechten Außenrand des Deckels 11 angelenkt ist. Zu Reinigungszwecken kann die Vorderwand abgeklappt werden.The front wall 14 is formed by a glass pane which is hinged at its lower edge to the right outer edge of the cover 11. The front wall can be folded down for cleaning purposes.
Der Innenbereich des Warenaufnahmeraumes 2 ist durch Einlegenböden 18, 18', 18'' in Warenfächer unterteilt. Auf jedem Einlageboden kann ein Tablett oder mehrere Tabletts mit zu präsentierender Ware abgestellt werden.The interior of the goods receiving space 2 is divided into product compartments by insert shelves 18, 18 ', 18' '. One tray or several trays with the goods to be presented can be placed on each shelf.
Von der Bedienseite aus ist jedes Warenfach bzw. jede durch einen Einlegeboden 18, 18', 18'' gebildete Etage zugänglich. Die Hinterwand 15 besteht aus mehreren Verschlußorganen 19, 19', 19'' und 19''', die lamellenartig übereinander stehen, um die geschlossene Hinterwand 15 auszubilden.Each goods compartment or each floor formed by a shelf 18, 18 ', 18''is accessible from the operating side. The rear wall 15 consists of several closure members 19, 19 ', 19''and19''', the Stand one above the other in the manner of a lamella to form the closed rear wall 15.
Jedes Verschlußorgan ist als in einem Querprofil 20, 20', 20'' und 20''' stehend gelagerte Klappe ausgebildet. Jede Klappe verschließt, ähnlich einer Lamelle, je ein zugeordnetes Warenfach des Warenaufnahmeraumes 2, wobei die Verschlußorgane einzeln betätigt werden können, indem sie zur Bedienseite der Vitrine hin in die durch gestrichelte Linien angedeutete waagerechte Position ausgeklappt werden. Das Tablett mit der jeweils gewünschten Ware wird vom jeweiligen Einlegeboden 18, 18', 18" herausgezogen, wobei eine Unterstützung durch das abgeklappte Verschlußorgan 19, 19`, 19" bzw. 19''' möglich ist. Nach der Entnahme der jeweils gewünschten Ware wird das Tablett auf den Einlageboden zurückgeschoben und das jeweilige Warenfach des Warenaufnahmeraumes 2 durch Zurückklappen des Verschlußorganes wieder verschlossen.Each closure member is designed as a flap standing upright in a transverse profile 20, 20 ', 20' 'and 20' ''. Each flap closes, similar to a lamella, an associated merchandise compartment of the merchandise receiving room 2, the locking members being able to be actuated individually by being folded out towards the operating side of the display case into the horizontal position indicated by dashed lines. The tray with the desired goods in each case is pulled out of the respective shelf 18, 18 ', 18 ", support being possible by means of the folded closure member 19, 19', 19" or 19 '' '. After the removal of the desired goods, the tray is pushed back onto the shelf and the respective goods compartment of the goods receiving space 2 is closed again by folding back the closure member.
Unter jedem Einlegeboden 18, 18', 18" verläuft, in Längsrichtung der Vitrine, eine langgestreckte Lampe 21 bzw. 21' bis 21"'.An elongated lamp 21 or 21 'to 21 "' runs under each shelf 18, 18 ', 18" in the longitudinal direction of the display case.
Die Lampe 21''' ist dabei unter die obere Ablageplatte 17 des Warenaufnahmeraumes 1 gesetzt.The lamp 21 '' 'is placed under the upper shelf 17 of the goods receiving space 1.
Jede Lampe 21 bis 21''' besteht aus einem Gehäuse mit zumindest teilweise lichtdurchlässigen Gehäusewänden 22, 22', 22" bzw. 22''', damit der im Gehäuse befindliche Leuchtkörper 23, 23`, 23'' bzw. 23''' Licht durch die Gehäusewände in das jeweils zugeordnete Warenfach des Warenaufnahmeraumes 2, daß sich jeweils unterhalb eines Einlegebodens 18, 18', 18'', bzw. der oberen Ablageplatte 17, befindet, ausgeleuchtet ist. Die Gehäusewände sind Bestandteil des Gehäuses jeder Lampe 21 bis 21'''. Das Gehäuse besteht hier aus einem Hohlprofil, welches wenigsten an einer seiner Endseiten luftdurchlässig ausgebildet ist und in einen der Abführung von Umluft dienenden Luftkanal 24 mündet. Dies ist hier durch die gestrichelten Bohrungen 25 bis 25''' angedeutet, die sich an einer Endseite bzw. Stirnseite einer Lampe 21 bis 21''' dort befinden, wo das als Hohlprofil vorliegende Gehäuse jeder Lampe an den Luftkanal 24 angeschlossen ist. Der Luftkanal 24 ist hier ein Profil bzw. eine schachtartige Ausgestaltung, die in Seitenwände 16 bzw. 16', die den kastenarigen Warenaufnahmeraum 2 seitlich begrenzen, integriert ist.Each lamp 21 to 21 '''consists of a housing with at least partially translucent housing walls 22, 22', 22 "or 22 ''', so that the luminous element 23, 23`, 23''or23''located in the housing 'Light is illuminated through the housing walls into the respectively assigned goods compartment of the goods storage room 2, which is located below a shelf 18, 18', 18 '' or the upper storage plate 17. The housing walls are Part of the housing of each lamp 21 to 21 '''. The housing here consists of a hollow profile, which is at least air-permeable on one of its end sides and opens into an air duct 24 which serves to discharge recirculated air. This is indicated here by the dashed bores 25 to 25 ''', which are located on one end or end of a lamp 21 to 21''' where the housing of each lamp, which is in the form of a hollow profile, is connected to the air duct 24. The air duct 24 is here a profile or a shaft-like configuration, which is integrated in side walls 16 or 16 ', which laterally delimit the box-type goods receiving space 2.
Etwa in einem der Vitrinenmitte entsprechenden Bereich weist jede Gehäusewand 22 bis 22''' jeder Lampe 21 bis 21''' einen zum Warenaufnahmeraum 2 hin offenen Durchbruch auf.Approximately in an area corresponding to the center of the display case, each housing wall 22 to 22 ″ ″ of each lamp 21 to 21 ″ ″ has an opening that is open toward the goods receiving space 2.
Durch den oder die Lüfter 10 wird über den Luftleitschacht 7 aus dem Warenaufnahmeraum 2 Luft in Richtung der hier eingezeichneten Pfeile gesaugt. Der Lüfter drückt die angesaugte Luft in die Kammer 5 und durch den darin installierten Wärmtauscher 4. Auf dem Weg durch den Wärmtauscher 4 wird die Luft gekühlt und wieder in den Warenaufnahmeraum 2 zurückgeführt.Air is drawn in through the air duct 7 through the air duct 7 from the goods receiving space 2 in the direction of the arrows shown here. The fan presses the sucked-in air into the chamber 5 and through the heat exchanger 4 installed therein. On the way through the heat exchanger 4, the air is cooled and returned to the goods receiving area 2.
Somit dienen im Boden des Warenaufnahmeraumes 2, der zugleich Deckel des Unterbaues 1 ist, befindliche Öffnungen 26, 27 als Luftauslaß bzw. Lufteinlaß, da sie Mündungen der zugeordneten unterbauseitigen Luftleitschächte 7 und 8 sind.Thus, openings 26, 27 located in the bottom of the goods receiving space 2, which is also the cover of the substructure 1, serve as air outlet or air inlet, since they are mouths of the associated substructure-side air ducts 7 and 8.
Die dem Warenaufnahmeraum 2 zugekehrte Oberfläche des Deckels 11 weist eine wannenartige Vertiefung 28 auf, die mit einer Abdeckplatte abgedeckt ist, welche in einem vorbestimmten Abstand vor der Vorderwand 14 und vor der Hinterwand 15 unter Ausbildung schlitzförmiger Erweiterungen 30, 31 der Öffnungen 26, 27 für Lufteinlaß und Luftauslaß endet.The surface of the lid 11 facing the goods receiving space 2 has a trough-like depression 28 which is covered with a cover plate, which ends at a predetermined distance in front of the front wall 14 and in front of the rear wall 15 to form slot-shaped extensions 30, 31 of the openings 26, 27 for the air inlet and air outlet.
Somit münden die Luftleitschächte 7, 8 in die wannenartige Vertiefung. Dabei trennt das Trennblech 6 den unterhalb der Abdeckung 29 befindlichen Mündungsbereich eines dem Luftauslaß zugeordneten saugseitigen Luftleitschachtes 7 mit der Öffnung 26 vom Mündungsbereich eines dem Lufteinlaß zugeordneten druckseitigen Luftleitschachtes 8 mit der Öffnung 27. Die schlitzförmigen Erweiterungen erstrecken sich über die gesamte Länge des Warenaufnahmeraumes und damit in etwa über die Vitrinenbreite.Thus, the air ducts 7, 8 open into the trough-like depression. The separating plate 6 separates the opening area below the cover 29 of a suction-side air duct 7 associated with the air outlet with the opening 26 from the opening region of a pressure-side air duct 8 associated with the air inlet with the opening 27. The slot-shaped extensions extend over the entire length of the goods receiving space and thus roughly across the width of the display case.
Jeder in eine Seitenwand 16 bzw. 16' integrierte Luftkanal ist luftleitend mit dem oberen Profil 13' verbunden. Das Profil 13' ist, ebenso wie die damit luftleitend verbundenen Profile 13 und 13''' ein Hohlprofil, in dem Luft strömen kann. Das untere Profil 13''' ist mit seinem der Hinterwand 15 zugekehrten Endbereich in die Nähe der wannenartigen Vertiefung und damit in die Nähe der schlitzförmigen Erweiterung 30, 31 bzw. des ansaugenden Luftleitschachtes 7 geführt.Each air duct integrated into a side wall 16 or 16 'is connected in an air-conducting manner to the upper profile 13'. The profile 13 ', like the profiles 13 and 13' '' connected to it in an air-conducting manner, is a hollow profile in which air can flow. The lower profile 13 '' 'is guided with its end region facing the rear wall 15 in the vicinity of the trough-like depression and thus in the vicinity of the slot-shaped extension 30, 31 or the intake air duct 7.
Luft, die aus dem Inneren des Warenaufnahmeraumes 2 über die Lampen 21 bis 21' sowie anschließend den Luftkanal 24 und die Profile 13', 13 und 13''' strömt, tritt aus dem Profil 13''' im Bereich des ansaugenden Luftleitschachtes 7 aus. Die in den Lampen 21 bis 21''' von ihren Gehäusewänden 22 bis 22''' umschlossenen Hohlräume werden von der Luft durchströmt, die dabei die von den Leuchtkörpern 23 bis 23''' erzeugte Wärme aufnimmt und abtransportiert. Die Vitrine ist dadurch mit einer vorteilhaften Lampenkühlung ausgerüstet.Air, which flows from the interior of the goods receiving space 2 via the lamps 21 to 21 'and then the air duct 24 and the profiles 13', 13 and 13 ''', emerges from the profile 13''' in the area of the intake air duct 7 , The cavities enclosed in the lamps 21 to 21 '''by their housing walls 22 to 22''' are flowed through by the air, which absorbs the heat generated by the luminous elements 23 to 23 '''and removed. The showcase is thus equipped with an advantageous lamp cooling.
Fig. 2 zeigt einen Längsschnitt der Vitrine gemäß Fig. 1. Gleiche Bauteile sind mit gleichen Bezugszahlen bezeichnet. Fig. 2 verdeutlicht insbesondere die mittige Anordnung der Durchbrüche 32 bis 32''' in den Lampen 21 bis 21''', insbesondere in ihren Gehäusewänden. Jeder Durchbruch kann ein einfacher Schlitz sein. Auch siebartige Lochungen sind durchaus möglich.FIG. 2 shows a longitudinal section of the display case according to FIG. 1. The same components are identified by the same reference numbers. Fig. 2 illustrates in particular the central arrangement of the openings 32 to 32 '' 'in the lamps 21 to 21' '', in particular in their housing walls. Any breakthrough can be a simple slit. Sieve-like perforations are also quite possible.
In Fig. 3 zeigt eine schematische Ansicht der Vitrine zur Veranschaulichung der den Warenaufnahmeraum 2 kühlenden Luftströme.3 shows a schematic view of the display case to illustrate the air flows cooling the goods receiving space 2.
Von der im Unterbau 1 untergebrachten Anlage zur Erzeugung gekühlter Umluft strömt unter der Wirkung eines Gebläses gekühlte Luft in einem ständigen Strom in Richtung des Pfeiles 33 von unten gegen die Abdeckplatte 29 der hier nicht weiter dargestellten wannenartigen Vertiefung in dem Deckel 11 des Unterbaus. Der Deckel 11 ist zugleich der Boden des Warenaufnahmeraumes 2. In der wannenartigen Vertiefung unter der Abdeckplatte 29 verteilt sich die gekühlte Luft und tritt über eine schlitzförmige Erweiterung 31 zwischen der Vorderwand 14 und einem Leitblech 32 aus, welches sich an der Vorderkante der die wannenartige Vertiefung abdeckenden Abdeckplatte 29 befindet. Es bildet sich ein Luftvorhang aus gekühlter Luft, der vor der Vorderwand 14 aufwärts strömt und sich im Warenaufnahmeraum 2 verteilt. Ein Teil der im Warenaufnahmeraum 2 befindlichen Luft tritt über Durchbrüche 32 bis 32''' in den Gehäusen von Lampen in den Hohlraum ein, der von den Gehäusewänden der Lampen umschlossen wird. In den Lampen strömt die eingetretene kühle Luft in Richtung der Pfeile 34 bis 34''' in jeder Lampe zu den End- bzw. Stirnseiten der Lampe, wobei das Lampeninnere gekühlt wird. Aus den Lampen tritt der Luftstrom in Luftkanäle 24 bzw. 24' über und strömt dann über die jeweils eine Seitenwand einfassenden Profile 13', 13 und 13''' zurück zur Hinterwand, dort insbesondere in den Bereich der schlitzförmigen Erweiterung 30 der Öffnung 26, in die der ansaugende Luftleitschacht 7 mündet. Damit ist der Kreislauf der kühlenden Umluftströmung unter Einbeziehung der gekapselten Lampen geschlossen.Cooled air flows under the action of a blower in a constant flow in the direction of arrow 33 from below against the cover plate 29 of the trough-like depression in the cover 11 of the substructure, which is accommodated in the substructure 1, for producing cooled circulating air. The lid 11 is also the bottom of the goods receiving space 2. In the trough-like depression under the cover plate 29, the cooled air is distributed and exits via a slot-shaped extension 31 between the front wall 14 and a baffle 32, which is located on the front edge of the trough-like depression covering cover plate 29 is located. An air curtain of cooled air forms, which flows upwards in front of the front wall 14 and is distributed in the goods receiving space 2. A portion of the air in the goods receiving space 2 enters through openings 32 to 32 '''in the housings of lamps into the cavity which is enclosed by the housing walls of the lamps. In the lamps, the cool air entering flows in the direction of arrows 34 to 34 '''in each Lamp to the end or end faces of the lamp, the interior of the lamp being cooled. The air flow passes from the lamps into air channels 24 and 24 'and then flows back through the profiles 13', 13 and 13 '''each enclosing a side wall, there in particular into the area of the slot-shaped extension 30 of the opening 26, into which the intake air duct 7 opens. This closes the cycle of the cooling circulating air flow, including the encapsulated lamps.
