Abstract

Under the display surface on which the goods are exposed, an evaporator (11) comprising a zig-zag array of tubes with a cover plate (6) is supplied with coolant from a cooling unit (9). Condensate is collected in a trough (13) and drained (14) into a container (15). The floor (7) of the display cabinet may be cooled by a special refrigerator or by integral coolant channels (7a) fed from a branch (10b) of the main circuit (10a).

Description

Die Erfindung bezieht sich auf eine Verkaufstheke oder -vitrine für Lebensmittel gemäß dem Oberbegriff des Patentanspruchs 1. Eine Verkaufstheke dieser Art ist aus der DE-A-2 505 390 bekannt.The invention relates to a sales counter or showcase for food according to the preamble of claim 1. A sales counter of this type is known from DE-A-2 505 390.

Bei der bekannten Verkaufstheke sind in deren Unterbau unterhalb des Warenausstellungsraums (Auslage) ein Kälteaggregat mit integriertem Verdampfer sowie ein Querstromgebläse angebracht, welches erwärmte Luft aus der Auslage absaugt und über den Verdampfer leitet. Ein Teil der am Verdampfer abgekühlten Luft wird über einen vertikalen Kühlluftkanal auf der Rückseite der Auslage in das oberste von drei übereinanderliegenden Auslagefächern geführt, von wo die Kühlluft in das darunterliegende Auslagefach absinkt. Das unterste, als Reservekühlfach ausgebildete Fach wird mit dem anderen Teil der am Verdampfer abgekühlten Luft direkt gespeist. Der Gesamtwirkungsgrad dieser Umluftkühlung ist indessen unbefriedigend. Zum einen muß für den Transport der Kühlluft eine erhebliche Lüfterleistung installiert werden. Ferner erwärmt sich die Kühlluft auf ihrem Weg durch den Kühlluftkanal, so daß Kühlleistung verloren geht, noch bevor die Kühlluft die zu kühlenden Waren erreicht hat. Schließlich ist die Ausbildung eines verhältnismäßig großen vertikalen Kühlluftkanals auf der für das Verkaufspersonal frei zugänglich zu haltenden Rückfront der Verkaufstheke aus praktischen Gründen nur an einem der beiden Längsenden der Verkaufstheke möglich. Diese bauliche Beschränkung führt jedoch dazu, daß an das gegenüberliegende Längsende der Verkaufstheke wenig oder nahezu keine Kühlluft gelangt, wenn die Auslage mit Waren gefüllt ist, welche die Kühlluftströmung in Längsrichtung der Auslage behindern.In the known sales counter, a refrigeration unit with an integrated evaporator and a cross-flow fan are installed in the substructure below the goods showroom (display), which sucks heated air out of the display and guides it over the evaporator. Part of the air cooled on the evaporator is led via a vertical cooling air duct on the back of the delivery into the top of three delivery compartments one above the other, from where the cooling air sinks into the delivery compartment underneath. The lowest compartment, designed as a reserve cooling compartment, is fed directly with the other part of the air cooled on the evaporator. However, the overall efficiency of this forced air cooling is unsatisfactory. On the one hand, a significant fan power must be installed to transport the cooling air. Furthermore, the cooling air heats up on its way through the cooling air duct, so that cooling capacity is lost even before the cooling air has reached the goods to be cooled. Finally, for practical reasons, the formation of a relatively large vertical cooling air duct on the rear front of the sales counter, which is freely accessible to the sales staff, is only possible at one of the two longitudinal ends of the sales counter. However, this structural limitation means that little or almost no cooling air reaches the opposite longitudinal end of the sales counter when the display is filled with goods which hinder the cooling air flow in the longitudinal direction of the display.

Die Aufgabe der Erfindung besteht demgegenüber darin, bei einer Verkaufstheke oder -vitrine den Kühlungswirkungsgrad ohne Vergrößerung des baulichen Aufwandes zu verbessern.In contrast, the object of the invention is to improve the cooling efficiency in a sales counter or display case without increasing the structural outlay.

Diese Aufgabe wird erfindungsgemäß durch die kennzeichnenden Merkmale des Patentanspruchs 1 gelöst.This object is achieved by the characterizing features of claim 1.

Vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung ergeben sich aus den Unteransprüchen.Advantageous refinements and developments of the invention result from the subclaims.

Die Erfindung beruht auf der Überlegung, den Verdampfer unterhalb der (oberen) Deckenplatte der Auslage anzubringen, d.h., an die höchste Stelle der Auslage. Da die erwärmte Luft innerhalb der Auslage zur Deckenplatte hin hochsteigt, wird sie unmittelbar an dem dort befindlichen Verdampfer abgekühlt. Das Kälteaggregat zum Speisen des Verdampfers mit flüssigem Kältemittel ist außerhalb der Auslage, z.B. in dem Unterbau der Verkaufstheke, oder außerhalb der Verkaufstheke angebracht. Die Verbindungsleitungen zwischen dem Kälteaggregat und dem Verdampfer verlaufen im Bereich der Auslage optisch unsichtbar in Tragholmen oder dgl.. Dasselbe gilt für eine oder mehrere Abflußleitungen zum Abführen von Kondenswasser, das sich in einer unterhalb des Verdampfers angeordneten Auffangwanne sammelt. Die Auffangwarne ist vorzugsweise mit einem Gefälle in Quer- und Längsrichtung der Auslage versehen, so daß der tiefste Punkt der Auffangwanne an einem Längsende der Auslage liegt, wo sich auch Tragholme der Verkaufstheke befinden. Der Verdampfer wird optisch von dem Kunden nicht bewußt wahrgenommen, wenn dessen Blick auf die Waren innerhalb der Auslage konzentriert ist. Zusätzlich kann im Bereich des Verdampfers die Frontscheibe mit einer undurchsichtigen Blende, Streifen oder dgl. versehen werden. Gegebenenfalls können zwischen Blende und Frontscheibe Preisschilder für die vertikal darunter liegenden Waren angebracht werden. Vorzugsweise erstreckt sich der Verdampfer im wesentlichen über die gesamte Länge der Auslage, so daß längs der gesamten Auslage eine gleichbleibende Kühlwirkung gesichert ist.The invention is based on the idea of installing the evaporator below the (upper) ceiling plate of the display, ie at the highest point of the display. As the heated air rises to the ceiling panel within the delivery, it is cooled directly on the evaporator located there. The refrigeration unit for supplying the evaporator with liquid refrigerant is located outside the display, for example in the base of the sales counter, or outside the sales counter. The connecting lines between the refrigeration unit and the evaporator run in the area of the display in an optically invisible manner in support bars or the like. The same applies to one or more drain lines for removing condensate that collects in a collecting trough arranged below the evaporator. The catch warning is preferably provided with a gradient in the transverse and longitudinal directions of the display, so that the lowest point of the catch trough lies at a longitudinal end of the display, where carrying bars of the sales counter are also located. The customer does not consciously perceive the evaporator visually when his gaze is focused on the goods within the delivery. In addition, in the area of Evaporator, the front window can be provided with an opaque screen, strip or the like. If necessary, price labels for the goods lying vertically underneath can be attached between the cover and the windscreen. The evaporator preferably extends essentially over the entire length of the delivery, so that a constant cooling effect is ensured along the entire delivery.

Die Erfindung wird an Hand zweier Ausführungsbeispiele in den Zeichnungen näher erläutert. Es zeigt:

The invention is explained in more detail using two exemplary embodiments in the drawings. It shows:
Fig. 1
a perspective view of a section of a conventional sales counter, in particular refrigerated counter, for food;
Fig. 2
a schematic view of the cooling system of a sales counter designed according to the invention, and
Fig. 3
a cross section through a second embodiment of a sales counter designed according to the invention, which has a modified design compared to FIG. 1.

Die in Fig. 1 perspektivisch dargestellte Verkaufstheke 1 weist einen Oberbau 2 und einen Unterbau 3 auf. Der Oberbau 2 erfüllt die beiden eigentlichen Funktionen der Verkaufstheke, nämlich Präsentation der Ware für den Kunden bei gleichzeitigem hygienischem Schutz und Kühlung der präsentierten Ware.The sales counter 1 shown in perspective in FIG. 1 has an upper structure 2 and a lower structure 3. The superstructure 2 fulfills the two actual functions of the sales counter, namely the presentation of the goods to the customer with simultaneous hygienic protection and cooling of the presented goods.

Zu diesem Zweck ist eine schräggestellte, tief nach unten gezogene Frontscheibe 4 (mit endseitigen Seitenscheiben) vorgesehen, welche die Auslage 1a der Verkaufstheke 1 zum Kunden hin abschließt. Ferner trägt der Oberbau 2 auf einer nach oben gezogenen Konsole eine Arbeitsplatte 5, wodurch das hinter der Verkaufstheke 1 stehende Verkaufspersonal bequem in die nach hinten zu offene und damit frei zugängliche Auslage 1a greifen kann. Die Oberseite der Auslage 1a wird durch eine Deckenplatte 6, z.B. in Form eines Zahlstreifens, gebildet, deren Breite im Vergleich zu der Arbeitsplatte 5 schmal ist. Die Deckenplatte 6 wird zumindest im Bereich der Längsenden von hohlen Tragholmen 8 (von denen in Fig. 1 nur ein Holm dargestellt ist) getragen, die an der Rückwand der Oberbaues 2 verankert sind. Die Tragholme 8 können bei anderen Thekenkonstruktionen statt auf der Rückseite auch auf der Vorderseite der Verkaufstheke 1 verlaufen, was für die Erfindung jedoch ohne Belang ist. Die Unterseite der Auslage 1a wird von einer Bodenwanne 7 gebildet, die mit der Unterkante der Frontscheibe 4 einen dichtenden Verschluß bildet.For this purpose, an inclined, deeply drawn down front pane 4 (with end-sided side windows) is provided, which closes the display 1a of the sales counter 1 towards the customer. Furthermore, the superstructure 2 carries a worktop 5 on an upwardly drawn console, as a result of which the sales staff standing behind the sales counter 1 can comfortably reach into the display 1 a which is open to the rear and thus freely accessible. The top of the display 1a is covered by a ceiling plate 6, e.g. in the form of a number strip, the width of which is narrow compared to the worktop 5. The ceiling plate 6 is supported at least in the region of the longitudinal ends by hollow support bars 8 (only one of which is shown in FIG. 1), which are anchored to the rear wall of the superstructure 2. With other counter constructions, the carrying struts 8 can also run on the front of the sales counter 1 instead of on the back, which is, however, irrelevant to the invention. The underside of the display 1a is formed by a floor pan 7, which forms a sealing closure with the lower edge of the front pane 4.

Erfindungsgemäß ist, wie aus den Fign. 2 und 3 ersichtlich ist, unterhalb der Deckenplatte 6 ein Verdampfer 11 zur Kühlung der Auslage 1a angebracht. Bei der Ausführungsform nach Fig. 2 verlaufen die Kältemittelrohre des Verdampfers 11 mäanderförmig über die gesamte Länge der Deckenplatte 6, so daß die Auslage 1a in Längsrichtung gleichmäßig gekühlt wird. Die erwärmte Luft innerhalb der Auslage 1a steigt nach oben zur Deckenplatte 6, wo sie auf den Verdampfer 11 trifft, dort angekühlt wird und nach unten gegen die Bodenwanne 7 absinkt.According to the invention, as shown in FIGS. 2 and 3, an evaporator 11 for cooling the delivery 1a is attached below the ceiling plate 6. In the embodiment according to FIG. 2, the refrigerant tubes of the evaporator 11 run in a meandering manner over the entire length of the ceiling plate 6, so that the delivery 1a is cooled uniformly in the longitudinal direction. The heated air inside the delivery 1 a rises up to the ceiling plate 6, where it meets the evaporator 11, is cooled there and sinks down against the floor pan 7.

Die Kältemittelzuführ zum Verdampfer 11 erfolgt von einem Kälteaggregat 9 aus über eine Kältemittelleitung 10a. Die Kältemittelleitung 10a verläuft im Bereich der Auslage 1a am einen Längsende der Verkaufstheke 1 durch den hohlen Tragholm 8 und ist damit von außen unsichtbar. In ähnlicher Weise erfolgt die Kältemittelabführ vom Verdampfer 11 über eine Kältemittelabflußleitung 12a, die an demselben Längsende, an dem die Kältemittelleitung 10a verläuft, oder am anderen Längsende der Verkaufstheke 1 durch den dort vorhandenen hohlen Tragholm 8 geführt ist und in das Kälteaggregat 9 mündet. Das Kälteaggregat 9 befindet sich entweder in dem Unterbau 3 der Verkaufstheke 1 oder außerhalb der Verkaufstheke 1 und kann gegebenenfalls zusätzlich über Zweigleitungen 10b und 12b Kältemittelkanäle 7a versorgen, welche innerhalb der Bodenwanne 7 integriert sind. Alternativ ist für die Kühöung der Bodenwanne 7 eine gesonderte (in den Zeichnungen nicht dargestellte) Kältemaschine vorgesehen.The refrigerant is supplied to the evaporator 11 from a refrigeration unit 9 via a refrigerant line 10a. The refrigerant line 10a runs in the area of the display 1a at one longitudinal end of the counter 1 through the hollow support bar 8 and is therefore invisible from the outside. In a similar manner, the refrigerant is removed from the evaporator 11 via a refrigerant drain line 12a, which is guided at the same longitudinal end on which the refrigerant line 10a runs or at the other longitudinal end of the sales counter 1 through the hollow support bar 8 there and opens into the refrigeration unit 9. The refrigeration unit 9 is located either in the substructure 3 of the sales counter 1 or outside the sales counter 1 and can optionally additionally supply refrigerant channels 7a via branch lines 10b and 12b, which are integrated within the floor pan 7. Alternatively, a separate cooling machine (not shown in the drawings) is provided for cooling the floor pan 7.

Unterhalb des Verdampfers 11 ist eine Auffangwanne 13 für Kondenswasser angebracht, die mit einem Gefälle in Längs- und in Querrichtung der Auslage 1a verlegt ist. Die tiefste Stelle der Auffangwanne 13 befindet sich daher in der Nähe eines Tragholms 8 am einen Längsende der Auslage 1a, wodurch es möglich ist, eine oder mehrere Abflußleitungen 14 für das Kondenswasser ebenfalls innerhalb des befreffenden Tragholms 8 und damit von außen unsichtbar zu verlegen. Die Abflußleitung(en) 14 münden, wie aus Fig. 2 ersichtlich ist, in einem Kondensat-Sammelbehälter 15 oder in einen Abflußanschluß für eine Kanalisation.Below the evaporator 11 there is a collecting trough 13 for condensed water, which is laid with a gradient in the longitudinal and transverse directions of the delivery 1a. The deepest point of the sump 13 is therefore in the vicinity of a support beam 8 at one longitudinal end of the display 1a, which makes it possible to lay one or more drain lines 14 for the condensed water also inside the relieving support beam 8 and thus invisibly from the outside. The drain line (s) 14, as can be seen from FIG. 2, open into a condensate collecting container 15 or into a drain connection for a sewage system.

Bei der Ausführungsform nach Fig. 3 ist eine gegenüber Fig. 1 angewandelte Bauform der Verkaufstheke 1 vorgesehen. Die im Bereich der beiden Längsseiten vorhandenen hohlen Tragholme 8 verlaufen in Fig. 3 vor der Frontscheibe 4 und stützen sich mit ihren unteren Enden jeweils an einem Arm 14 ab, der am Unterbau 2 an Schwenklagern 14a gelagert ist. Die aus den Armen 14, den Tragholmen 8, der Frontscheibe 4 und der Deckenplatte 6 gebildete Haube umgibt die Auslage 1a und läßt sich um die Schwenklager 14a bezüglich der Bodenplatte 7 ausschwenken, wodurch sich die Auslage 1a leichter reinigen läßt. Der unterhalb der Deckenplatte 6 angebrachte Verdampfer 11 weist in Längsrichtung der Auslage 1a verlaufende Kältemittelrohre auf, die an ihren Enden zu einem kontinuierlichen Strang verbunden sind. Die Auffangwanne 13 ist ein- oder zweistufig ausgebildet. Seitlich von der Auffangwanne 13 oder unmittelbar darunter ist eine Beleuchtungsvorrichtung 16, z.B. eine oder mehrere Leuchtstoffröhren, untergebracht.In the embodiment according to FIG. 3, a construction of the sales counter 1 that is modified compared to FIG. 1 is provided. The in the area of the two long sides Existing hollow spars 8 run in Fig. 3 in front of the windshield 4 and are supported with their lower ends on an arm 14 which is mounted on the base 2 on pivot bearings 14a. The hood formed from the arms 14, the support bars 8, the front window 4 and the cover plate 6 surrounds the display 1a and can be pivoted out about the pivot bearing 14a with respect to the base plate 7, as a result of which the display 1a can be cleaned more easily. The evaporator 11 attached below the ceiling plate 6 has refrigerant pipes running in the longitudinal direction of the delivery 1 a, which are connected at their ends to form a continuous strand. The drip pan 13 is designed in one or two stages. An illumination device 16, for example one or more fluorescent tubes, is accommodated to the side of the collecting trough 13 or immediately below it.

Um den Verdampfer 11 optisch abzublenden, kann hinter der Frontscheibe 4 oder als Bestandteil der Frontscheibe 4 eine schmale Blende 17 vorgesehen werden. Zwischen Blende 17 und Frontscheibe 4 können in nicht dargestellter Weise Preisschilder für die vertikal darunter befindlichen Waren angebracht werden.In order to visually dazzle the evaporator 11, a narrow screen 17 can be provided behind the front screen 4 or as part of the front screen 4. Price plates for the goods located vertically underneath can be attached between the panel 17 and the front screen 4 in a manner not shown.

Es versteht sich, daß die Erfindung nicht auf Verkaufstheken beschränkt ist, sondern ebensogut bei geschlossenen Verkaufsvitrinen anwendbar ist, aus denen der Kunde die ausgestellten, gekühlten Waren entnehmen kann.It goes without saying that the invention is not limited to sales counters, but can equally well be used in closed sales cabinets from which the customer can take the refrigerated goods on display.

Zusammengefaßt lassen sich mit Hilfe der Erfindung folgende Vorteile erzielen:

  • 1. Die Kühlluft wird nicht mehr über Ventilatoren oder dergleichen zur Ware transportiert, sondern es wird konstruktiv das natürliche Kältegefälle ausgenutzt, bei welcher Kälte stets von oben nach unten fällt. Da nur das in der Auslage vorhandene Luftvolumen gekühlt wird, das aufgrund des natürlichen Kältegefälles zirkuliert, wird der ausgestellten Ware keine Feuchtigkeit entzogen, wie das der Fall ist, wenn ein kontinuierlicher Strom trockener Kühlluft durch die Auslage hindurchgeführt wird. Eine künstliche Befeuchtung der Ware ist bei der erfindungsgemäßen Verkaufstheke entbehrlich.
  • 2. Infolge der Absinkens der an der Decke der Auslage gekühlten Luft zum Boden der Auslage kann die Ware viel höher in der Auslage dekoriert werden als dies bei Hindurchführung eines kontinuierlichen Stroms trockener Kühlluft durch die Auslage möglich ist. Bei dieser bekannten Art der Umluftkühlung stellt die Ware ein Strömungshindernis für die Kaltluft dar, deren Strömungsgeschwindigkeit möglichst groß sein sollte. Im Falle der erfindungsgemäßen Verkaufstheke ist die Strömungsgeschwindigkeit der infolge natürlichen Kältgefälles zirkulierenden Luft relativ gering, so daß der Strömungswiderstand der Ware vernachlässigbar ist.
  • 3. Die erfindungsgemäße Kühlung der in der Auslage erwärmten, hochsteigenden Luft an der Decke der Auslage kann wirkungsvoll durch eine zusätzliche Kühlung der Bodenwanne der Auslage unterstützt werden.
In summary, the following advantages can be achieved with the aid of the invention:
  • 1. The cooling air is no longer transported to the goods via fans or the like, but the natural cold gradient becomes constructive exploited, in which cold always falls from top to bottom. Since only the volume of air in the display, which circulates due to the natural cold gradient, is cooled, no moisture is removed from the goods on display, as is the case when a continuous flow of dry cooling air is passed through the display. Artificial moistening of the goods is unnecessary in the sales counter according to the invention.
  • 2. As a result of the cooling of the air cooled on the ceiling of the display to the bottom of the display, the goods can be decorated much higher in the display than is possible with a continuous flow of dry cooling air through the display. In this known type of circulating air cooling, the goods represent an obstacle to the flow of cold air, the flow speed of which should be as high as possible. In the case of the sales counter according to the invention, the flow rate of the air circulating as a result of natural cold gradients is relatively low, so that the flow resistance of the goods is negligible.
