Description

Die Erfindung betrifft einen Kühltisch mit einem umluftgekühlten Kühlraum, der eine Reihe aus nebeneinander angeordneten Kühlfächern aufweist, und mit einem Kühlaggregat, das einen Verdampfer mit Gebläse und eine Steuerung mit Bedienungseinrichtung aufweist.The invention relates to a cooling table with an air-cooled cooling space, which has a row of cooling compartments arranged side by side, and with a cooling unit, which has an evaporator with a fan and a control with an operating device.

Bekannte Kühltische mit umluftgekühltem Kühlraum weisen zwischen einzelnen Kühlfächern Verdampfer auf, durch welche von einem Gebläse Luft angesaugt wird, die dabei abgekühlt wird. Zur Aufnahme solcher Verdampfer müssen die Zwischenräume zwischen einzelnen Kühlfächern ausreichend groß bemessen sein. Wenn bei größeren Kühlräumen mehrere Verdampfer vorzusehen sind, erweisen sich ferner, vor allem auch unter hygienischen Gesichtspunkten, die Pflege und Wartung der Kühlaggregate als sehr aufwendig. Auch ist die Luftzirkulation durch den Verdampfer häufig durch an diesem anliegende Ware behindert. Im Extremfall kann es sogar zu einer Beschädigung der Verdampfer durch Ware kommen, wenn diese nicht sorgfältig in den Kühlfächern gelagert wird.Known cooling tables with air-cooled cooling space have evaporators between individual cooling compartments, through which air is sucked in by a blower, which is cooled in the process. To accommodate such evaporators, the gaps between individual cooling compartments must be large enough. If several evaporators are to be provided in larger cold rooms, the care and maintenance of the cooling units also prove to be very complex, especially from a hygienic point of view. The air circulation through the evaporator is also often hampered by the goods in contact with it. In extreme cases, the evaporators can even be damaged by goods if they are not stored carefully in the refrigerated compartments.

Es ist Aufgabe der Erfindung, einen Kühltisch zu schaffen, der problemlos in einem hygienisch einwandfreien Zustand zu halten ist, dessen Kühlaggregat leicht zu pflegen und zu warten ist und der eine verbesserte Luftzirkulation aufweist.It is an object of the invention to provide a cooling table which is easy to keep in a hygienically perfect condition, whose cooling unit is easy to maintain and maintain, and which has improved air circulation.

Bei einem Kühltisch nach der Erfindung wird die Aufgabe dadurch gelöst, daß das Kühlaggregat an einer Stirnseite des Kühlraumes angeordnet ist, daß in einem oberen Bereich des Kühlraumes über die Kühlfächer hinweg ein Lüftungskanal verläuft, der in die Kühlfächer gerichtete Austrittsöffnungen aufweist, und daß das Gebläse über den Verdampfer die Luft aus den Kühlfächern des Kühlraumes absaugt und in den Lüftungskanal wieder zurückbläst. Der wesentliche Vorteil besteht bei einem erfindungsgemäßen Kühltisch in einem verdampferfreien, durchgängigen Kühlraum. Die Innenwand des Kühlraumes kann daher im wesentlichen glatt und durchgängig gestaltet werden, so daß eine hygienisch einwandfreie Reinigung schnell und leicht erfolgen kann. Da nur ein einziger Verdampfer für alle Kühlfächer an einer Stirnseite des Kühlraumes vorgesehen ist, ist dessen Beschädigungsgefahr auf ein Minimum reduziert. Durch den Verdampfer wird die Luft aus dem Kühlraum abgesaugt und mittels eines Gebläses in einen Lüftungskanal eingeblasen, der über die einzelnen Kühlfächer hinweg verläuft und über den die abgekühlte Luft in die Kühlfächer hineingeblasen wird. Damit kann innerhalb des Kühlraumes eine exakt ausgerichtete Umluft-Bewegung stattfinden, die die eingelagerte Ware gleichmäßig kühlt. In der Regel wird dazu der Lüftungskanal unmittelbar unter der Decke des Kühlraumes angeordnet.In a cooling table according to the invention, the object is achieved in that the cooling unit is arranged on an end face of the cooling space, that in an upper region of the cooling space, a ventilation duct runs across the cooling compartments and has outlet openings directed into the cooling compartments, and in that the fan sucks the air out of the cooling compartments of the cold room via the evaporator and blows it back into the ventilation duct. The main advantage of a cooling table according to the invention is an evaporator-free, continuous cooling space. The inner wall of the cooling room can therefore be made essentially smooth and continuous, so that hygienically perfect cleaning can be done quickly and easily. Since only a single evaporator is provided for all cooling compartments on one end of the cooling space, the risk of damage is reduced to a minimum. The air is sucked out of the cooling space by the evaporator and blown into a ventilation duct by means of a blower which runs over the individual cooling compartments and through which the cooled air is blown into the cooling compartments. This enables a precisely aligned circulating air movement to take place within the cooling room, which cools the stored goods evenly. As a rule, the ventilation duct is arranged directly under the ceiling of the cold room.

In einer vorteilhaften Ausgestaltung bildet der Verdampfer einen stirnseitigen Abschluß des Kühlraumes. Damit steht zum Absaugen der Luft im Kühlraum eine sehr große Fläche zur Verfügung. Um einen hohen Durchsatz durch den Verdampfer zu ermöglichen, kann das Gebläse ein Querstromgebläse sein. Üblicherweise wird dieses Gebläse innerhalb eines sich an den Verdampfer anschließenden, sich trichterartig verjüngenden Kanals montiert.In an advantageous embodiment, the evaporator forms an end closure of the cooling space. This means that there is a very large area available for extracting air from the refrigerator. In order to enable a high throughput through the evaporator, the blower can be a cross-flow blower. This fan is usually installed within a channel which adjoins the evaporator and tapers like a funnel.

Bevorzugt wird vorgesehen, daß das Gebläse innerhalb eines Ausblaskanales montiert ist und durch diesen die Luft in den Lüftungskanal einbläst. Der im Anschluß an den Verdampfer angeordnete Kanal setzt sich mit seiner Verjüngung als Ausblaskanal fort, der unmittelbar in den Lüftungskanal einmündet. Innerhalb dieses Ausblaskanales, nur wenig hinter der Verjüngung, ist das Gebläse strömungstechnisch günstig angeordnet. Eine solche Anordnung von Verdampfer, Gebläse und Ausblaskanal ermöglicht einen effizienten Luftdurchsatz.It is preferably provided that the fan is mounted within a blow-out duct and through this the air is blown into the ventilation duct. The duct arranged after the evaporator continues with its tapering as a blow-out duct, which opens directly into the ventilation duct. Within this blow-out channel, just behind the taper, the fan is arranged in a fluidically favorable manner. Such an arrangement of evaporator, blower and blow-out channel enables efficient air throughput.

Der Kühltisch nach der Erfindung weist nur ein einziges Kühlaggregat auf, das bevorzugt als Modul ausgebildet ist, das von einem Rahmen getragen und komplett aus dem Kühltisch herausziehbar ist. Damit ist das Kühlaggregat frei zugänglich und läßt sich auf einfache Weise pflegen und warten. Ferner ist durch die modulare Bauweise ein rasches Auswechseln des Kühlaggregates möglich und es wird für verschiedene Baureihen lediglich ein einziges Kühlaggregat benötigt, so daß durch die leichte Austauschbarkeit und Lagerhaltung eine höchstmögliche Sicherheit gewährleistet und eventuelle Ausfallzeiten in Grenzen gehalten werden können.The cooling table according to the invention has only a single cooling unit, which is preferably designed as a module, which is supported by a frame and can be completely pulled out of the cooling table. The cooling unit is thus freely accessible and can be easily maintained and serviced. Furthermore, due to the modular design, the cooling unit can be replaced quickly and only one cooling unit is required for different series, so that the easy interchangeability and storage ensure maximum safety and possible downtimes can be kept within limits.

In Ausgestaltung der Erfindung ist vorgesehen, daß das Modul eine Frontblende aufweist und daß die Steuerung mit Bedienungseinrichtung in die Frontblende integriert ist. Damit ist eine Vorderfront erreicht, die keine zusätzlichen Türen benötigt und über die das Kühlaggregat direkt bedient und kontrolliert werden kann.In an embodiment of the invention it is provided that the module has a front panel and that the control with operating device is integrated in the front panel. This achieves a front that does not require any additional doors and through which the cooling unit can be operated and controlled directly.

Alternativ kann der Verdampfer an eine externe Kühlmaschine angeschlossen sein. Auch ein solches Kühlaggregat ist als Modul ausgebildet, so daß der Wechsel von einem Modul mit vollständigem Kühlaggregat zu einem Aggregat, das z.B. an den Anschluß einer externen Zentral-Kühleinrichtung geeignet ist, problemlos vollzogen werden kann. Notwendige Anschlußarmaturen wie Expansionsventil und Magnetventile sind unmittelbar neben dem Verdampfer angeordnet. Bei einem vollständigen Kühlaggregat ist vorgesehen, daß der Verdampfer und ein Verflüssiger getrennt übereinander angeordnet sind und daß der Verflüssiger über eine frontseitige Tür für sich zugänglich ist. Um den Wirkungsgrad eines Verflüssigers möglichst hoch zu halten, ist dieser häufig zu reinigen. Durch die vorgesehene Tür ist dieses sehr leicht und ohne jedes Werkzeug möglich.Alternatively, the evaporator can be connected to an external cooling machine. Such a cooling unit is also designed as a module, so that the change from a module with a complete cooling unit to a unit that e.g. is suitable for the connection of an external central cooling device, can be carried out easily. Necessary connection fittings such as expansion valve and solenoid valves are located directly next to the evaporator. In the case of a complete cooling unit, it is provided that the evaporator and a condenser are arranged separately one above the other and that the condenser is accessible to itself via a front door. In order to keep the efficiency of a condenser as high as possible, it must be cleaned frequently. The door provided makes this very easy and possible without any tools.

Für die Isolierung eines Kühltisches nach der Erfindung ist vorgesehen, daß der Kühlraum und die die Kühlfächer frontseitig schließenden Schubladenblenden und Türen doppelwandig mit zwischenliegenden Isolierplatten ausgebildet sind, die bevorzugt aus FCKW-freiem - gemäß Montrealer Konferenz - Polyurethan-Hartschaum bestehen. In der Gehäusewand bzw. in den Schubladenblenden und Türen treten bei einer solchen Konstruktion praktisch keine Kältebrücken auf. Ferner können solche Hartschaumplatten keine Schäumverbindung mit den Gehäusewänden eingehen. Darüber hinaus weisen Hartschaumplatten aus Polyurethan, z.B. 30M/HFA, bei einer Stärke von 1,8 kg/cm² einen K-Wert von 0,64 auf und sind daher hervorragend zu Isolationszwecken geeignet. Letztlich sind solche Isolierplatten auch recyclingfähig.For the insulation of a cooling table according to the invention it is provided that the cooling space and the drawer shutters and doors closing the cooling compartments at the front are double-walled with intermediate insulating plates, which preferably consist of CFC-free - according to the Montreal conference - rigid polyurethane foam. Such a construction is practical in the housing wall or in the drawer panels and doors no cold spots. Furthermore, such rigid foam panels cannot enter into a foam connection with the housing walls. In addition, rigid foam panels made of polyurethane, for example 30M / HFA, have a K value of 0.64 at a thickness of 1.8 kg / cm² and are therefore ideally suited for insulation purposes. Ultimately, such insulation panels are also recyclable.

In Ausgestaltung der Erfindung kann weiter vorgesehen werden, daß der Lüftungskanal als Flachkanal und über nahezu die gesamte Tiefe des Kühlraumes ausgebildet ist. Die z.B. über einen Ausblaskanal in den Flachkanal eingeblasene Kaltluft kann sich über die gesamte Oberseite des Kühlraumes verteilen und durch die Austrittsöffnungen in diesen eintreten, wodurch sich eine weitgehend gleichmäßige Umluft-Strömung einstellt. Dabei ist vorteilhafterweise ein Kanal von rechteckigem Querschnitt vorgesehen.In an embodiment of the invention it can further be provided that the ventilation duct is designed as a flat duct and over almost the entire depth of the cooling space. The e.g. Cold air blown into the flat duct via a blow-out duct can be distributed over the entire upper side of the cooling space and enter through the outlet openings, as a result of which a largely uniform circulating air flow is established. A channel of rectangular cross section is advantageously provided.

Häufig sind die Kühlfächer mit Teleskop-Schubladen ausgestattet, deren Teleskopzüge schräg nach hinten abfallen, damit die Schubladen sich unter Schwerkrafteinfluß selbständig schließen können. Bei solchen Teleskop-Schubladen-Kühlfächern wird bevorzugt, daß sich der Querschnitt des Lüftungskanals zur Rückwand des Kühlraumes hin vergrößert, was zu einer gleichmäßigen Kaltluftverteilung beiträgt.The cooling compartments are often equipped with telescopic drawers, the telescopic pulls of which drop diagonally to the rear so that the drawers can close automatically under the influence of gravity. In such telescopic drawer cooling compartments, it is preferred that the cross section of the ventilation duct increases towards the rear wall of the cooling space, which contributes to an even distribution of cold air.

Die Austrittsöffnungen des Luftkanals sind, - in Strömungsrichtung der Luft gesehen - in einem vorderen Bereich eines jeden Kühlfaches quer zur Strömungsrichtung im kühlraumseitigen Boden des Luftkanals angeordnet; ferner ist am Ende des Luftkanals eine große Austrittsöffnung vorgesehen.The outlet openings of the air duct are, seen in the flow direction of the air, arranged in a front region of each cooling compartment transversely to the flow direction in the bottom of the air duct on the cooling chamber side; a large outlet opening is also provided at the end of the air duct.

Damit wird ein gleichmäßiger Luft-Austritt in jedes Kühlfach erreicht, wobei die Kühlluft insbesondere in den Bereich zwischen den einzelnen Kühlfächern eintritt, wo sie frei und ungehindert zirkulieren kann. Die große Austrittsöffnung am Ende des Lüftungskanals stellt den Druckausgleich zwischen Kühlraum und Ende des Lüftungskanals sicher.A uniform air outlet is thus achieved in each cooling compartment, the cooling air entering in particular in the area between the individual cooling compartments, where it can circulate freely and unhindered. The large outlet opening at the end of the ventilation duct ensures pressure equalization between the cooling room and the end of the ventilation duct.

In weiterer Ausgestaltung der Erfindung können vor den Austrittsöffnungen Abrißkanten aufweisende Profile angeordnet sein. Solche Abrißkanten können z.B. durch aufgeklebte Leisten gebildet sein, über die die Luft hinwegströmen muß, wobei die Luftströmung vor Wiederanlegen an den Kanalboden unmittelbar in die Austrittsöffnung gerichtet ist.In a further embodiment of the invention, profiles having tear-off edges can be arranged in front of the outlet openings. Such tear-off edges can e.g. be formed by glued strips, over which the air must flow, the air flow being directed directly into the outlet opening before re-application to the channel floor.

Ferner kann eine Reihe von Austrittsöffnungen parallel zur Strömungsrichtung im kühlraumseitigen Boden des Lüftungskanals zu dessen Rückseite hin und parallel zu dieser angeordnet sein, die ebenfalls insbesondere bei schräg liegenden Teleskopauszügen für eine gleichmäßige Durchlüftung sorgen.Furthermore, a number of outlet openings can be arranged parallel to the direction of flow in the bottom of the ventilation duct on the cooling chamber side towards the rear and parallel to the latter, which likewise ensure uniform ventilation, particularly in the case of inclined telescopic pull-outs.

Eine gute Umluftströmung im Kühlraum wird letztlich dadurch unterstützt, wenn sich der Querschnitt oder die Anzahl der Austrittsöffnungen in Strömungsrichtung vergrößern.A good circulating air flow in the refrigerator is ultimately supported if the cross section or the number of outlet openings increases in the direction of flow.

In Ausgestaltung der Erfindung kann ferner vorgesehen werden, daß der Kühltisch eine sich über ein oder mehrere Kühlfächer erstreckende, durch eine Tischplattenaussparung zugängliche Wanne aufweist, zwischen deren Boden und den Kühlfächern der Lüftungskanal als Flachkanal verläuft. Die Wanne und die Kühlfächer sind vorteilhafterweise in einem von der Tischplatte getrennten Tischkorpus angeordnet, der insgesamt unter eine Tischplatte untergebaut werden kann. Alternativ ist aber auch möglich, die Wanne in eine Tischplattenaussparung einzulassen. Die Wanne wird bei der Ausführungsform nach der Erfindung ebenfalls durch Umluft gekühlt, so daß Kühlrohre entfallen und die Wanne folglich leicht zu reinigen ist. Die Wanne wird von dem Kühlluftstrom durchströmt, so daß alle Wannenbereiche auf gleiche Temperatur gebracht werden.In an embodiment of the invention it can further be provided that the cooling table has a trough which extends over one or more cooling compartments and is accessible through a table top recess, between the bottom and the cooling compartments of which the ventilation duct runs as a flat duct. The tub and the cooling compartments are advantageously in one of the Table top arranged separate table body, which can be built under a table top. Alternatively, it is also possible to insert the tub into a table top recess. In the embodiment according to the invention, the tub is also cooled by circulating air, so that cooling pipes are eliminated and the tub is consequently easy to clean. The flow of cooling air flows through the tub, so that all tub areas are brought to the same temperature.

Der Wannenboden ist vorteilhafterweise zu einem Ablauf hin geneigt ausgebildet, wobei der Ablauf durch ein Absperrorgan, z.B. einen Stöpsel, Hahn oder ein Ventil, absperrbar ist.The trough bottom is advantageously inclined towards a drain, the drain being blocked by a shut-off device, e.g. a stopper, tap or valve that can be shut off.

Weitere Merkmale der Erfindung sind in den Unteransprüchen angegeben.Further features of the invention are specified in the subclaims.

Bei dem in Fig. 1 gezeigten Kühltisch wird ein Kühlraum 1 von vier Kühlfächern 2, 3, 4, 5 gebildet. Die Kühlfächer 4, 5 sind durch Türen 6, 6 und die Kühlfächer 2, 3 durch Schubladenblenden 7 geschlossen. In einem weiteren Fach 8 ist ein Kühlaggregat an einer Stirnseite des Kühlraumes 1 angeordnet. Alle Fächer weisen dabei Gastro-Normmaße auf. Wie Fig. 2 vereinfacht zeigt, besteht das Kühlaggregat aus einem Verdampfer 9 mit einem Gebläse 10 und einer Steuerung, deren Bedienungseinrichtung 11 in eine Frontblende 12 eingelassen und damit von außen zugänglich ist (vgl. Fig. 1). Der Verdampfer 9 des Kühlaggregates bildet einen teilweisen Abschluß der Stirnseite 13 des Kühlraumes 1. Der übrige Bereich der Stirnseite 13 wird durch eine isolierende Gehäusewand verschlossen. Im oberen Bereich des Kühlraumes 1 verläuft über die Kühlfächer 2 bis 5 ein Lüftungskanal 14 mit Austrittsöffnungen 15, 16. Die eingetragenen Pfeile verdeutlichen, wie das Gebläse 10 über den Verdampfer 9 hinweg die Luft aus dem Kühlraum 1 absaugt und in den Lüftungskanal 14 einbläst. Dazu wird hinter dem Verdampfer 9 die Luft in einen Kanal geführt, der sich trichterartig verjüngt und in einen Ausblaskanal 17 übergeht, der lösbar an dem Lüftungskanal 14 angeschlossen ist. Das Gebläse 10 ist als Querstromgebläse ausgebildet und ist innerhalb des Ausblaskanales 17 montiert.In the cooling table shown in FIG. 1, a cooling space 1 is formed by four cooling compartments 2, 3, 4, 5. The cooling compartments 4, 5 are closed by doors 6, 6 and the cooling compartments 2, 3 by drawer panels 7. In a further compartment 8, a cooling unit is arranged on an end face of the cooling room 1. All subjects have standard catering dimensions. As FIG. 2 shows in simplified form, the cooling unit consists of an evaporator 9 with a blower 10 and a controller, the operating device 11 of which is embedded in a front panel 12 and is therefore accessible from the outside (cf. FIG. 1). The evaporator 9 of the cooling unit forms a partial closure of the end face 13 of the cooling space 1. The remaining area of the end face 13 is closed by an insulating housing wall. In the upper area of the cooling room 1, a ventilation duct 14 with outlet openings 15, 16 runs over the cooling compartments 2 to 5. The arrows entered illustrate how the blower 10 sucks the air out of the cooling space 1 through the evaporator 9 and blows it into the ventilation duct 14. For this purpose, the air is guided behind the evaporator 9 into a channel which tapers like a funnel and merges into a blow-out channel 17 which is detachably connected to the ventilation channel 14. The blower 10 is designed as a cross-flow blower and is mounted inside the blow-out duct 17.

Fig. 3 zeigt in Draufsicht die Anordnung der Austrittsöffnungen 15, 16 innerhalb des Lüftungskanales 14 und weiter, daß der Lüftungskanal 14 über nahezu die gesamte Tiefe des Kühlraumes 1 als Flachkanal ausgebildet ist. Die Austrittsöffnungen 16 liegen, in Strömungsrichtung der Luft gesehen, in einem vorderen Bereich eines jeden Kühlfaches 2, 3, 4, 5, wobei die Strömungsrichtung im Lüftungskanal 14 durch Pfeile 18 angedeutet ist. Am Ende des Lüftungskanals 14 ist eine große Austrittsöffnung 15 wie die Austrittsöffnungen 16 quer zur Strömungsrichtung 18 in den Boden 19 des Lüftungskanales 14 eingelassen. Um das Austreten der Luft durch die Austrittsöffnungen 16 zu verbessern, sind vor den Austrittsöffnungen 16 Profile 20 angebracht, die hinter ihrer Abrißkante 21 für eine Wirbelbildung sorgen und damit einen guten Luftaustritt durch die Austrittsöffnungen 16 ermöglichen, wie die die Strömungsrichtung anzeigenden Pfeile 22 in Fig. 6 zeigen. Entlang der Rückwand 23 des Lüftungskanals 14 sind noch weitere Austrittsöffnungen 24 parallel zur Rückwand 23 angeordnet.Fig. 3 shows a top view of the arrangement of the outlet openings 15, 16 within the ventilation duct 14 and further that the ventilation duct 14 is formed over almost the entire depth of the cooling space 1 as a flat channel. The outlet openings 16 are, seen in the direction of flow of the air, in a front region of each cooling compartment 2, 3, 4, 5, the direction of flow in the ventilation duct 14 being indicated by arrows 18. At the end of the ventilation duct 14, a large outlet opening 15, like the outlet openings 16, is let into the bottom 19 of the ventilation duct 14 transversely to the flow direction 18. In order to improve the escape of the air through the outlet openings 16, profiles 20 are attached in front of the outlet openings 16, which provide a vortex formation behind their tear-off edge 21 and thus enable good air outlet through the outlet openings 16, as shown by the arrows 22 in FIG 6 show. Further outlet openings 24 are arranged parallel to the rear wall 23 along the rear wall 23 of the ventilation duct 14.

Fig. 4 zeigt ein komplettes Kühlaggregat, welches als von einem Rahmen 26 getragenes Modul 25 ausgebildet und komplett aus dem Fach 8 des Kühlraumes herausziehbar ist. Das Modul 25 ist mit einer Frontblende 12 versehen, in der die Steuerung mit der Bedienungseinrichtung 11 integriert ist. Das Modul 25 ist ein vollständiges Kühlaggregat, das neben dem Verdampfer 9 auch einen Verflüssiger 28 aufweist. Verdampfer 9 und Verflüssiger 28 sind, voneinander getrennt, übereinander im Rahmen 26 angeordnet. Das bietet die Möglichkeit, den Verflüssiger 28 für sich über eine frontseitige Tür 29 für Wartungszwecke und Reinigung zugänglich zu machen (vgl. Fig. 1 und 2).Fig. 4 shows a complete cooling unit, which is designed as a module 25 carried by a frame 26 and can be pulled out completely from the compartment 8 of the cooling room is. The module 25 is provided with a front panel 12, in which the control with the operating device 11 is integrated. The module 25 is a complete cooling unit which, in addition to the evaporator 9, also has a condenser 28. The evaporator 9 and the condenser 28 are, separated from one another, arranged one above the other in the frame 26. This offers the possibility of making the condenser 28 accessible for maintenance purposes and cleaning via a front door 29 (cf. FIGS. 1 and 2).

Wie Fig. 5 - ein nichtmaßstäblicher Querschnitt durch einen Kühltisch im Bereich einer Schublade - zeigt, ist der Kühlraum 1 und sind die die Kühlfächer 2 bis 5 frontseitig schließenden Schubladenblenden 7 und Türen 6 doppelwandig mit zwischenliegenden Isolierplatten 30 ausgeführt, was eine hervorragende, kältebrückenfreie Wandkonstruktion ermöglicht. Fig. 5 zeigt ferner noch einen Lüftungskanal 31, dessen Querschnitt sich zur Rückwand 32 des Kühlraumes 1 hin vergrößert. Durch eine solche Ausführung des Querschnittes des Lüftungskanals 31 wird hier berücksichtigt, daß die Schublade 33 mit schrägliegenden Teleskopzügen 34 ausgestattet ist, damit sie sich unter Schwerkrafteinfluß selbständig schließen kann. Durch die schrägen Teleskopzüge 34 muß ein zur Rückwand 32 hin vergrößerter Raum mit kalter Luft durch die Austrittsöffnungen 16 des Kanals 31 versorgt werden. Um dies sicher zu gewährleisten, ist der Querschnitt des Lüftungskanals 31 zur Rückwand 32 hin ebenfalls vergrößert. Die Seitenwände 35 der Schublade 33 sind mit Löchern 36 versehen, die die Luftzirkulation entsprechend den Pfeilen in Fig. 2 im Kühlraum 1 unterstützen.As shown in FIG. 5 - a cross-section through a cooling table in the area of a drawer, which is not to scale, the cooling space 1 and the drawer shutters 7 and doors 6 closing the cooling compartments 2 to 5 on the front are double-walled with intermediate insulating plates 30, which is an excellent, cold bridge-free wall construction enables. 5 also shows a ventilation duct 31, the cross section of which widens towards the rear wall 32 of the cooling space 1. Such a design of the cross section of the ventilation duct 31 takes into account here that the drawer 33 is equipped with inclined telescopic cables 34 so that it can close automatically under the influence of gravity. Due to the inclined telescopic cables 34, a space enlarged towards the rear wall 32 must be supplied with cold air through the outlet openings 16 of the channel 31. To ensure this reliably, the cross section of the ventilation duct 31 towards the rear wall 32 is also enlarged. The side walls 35 of the drawer 33 are provided with holes 36, which support the air circulation in the cold room 1 according to the arrows in FIG. 2.

Die Fig. 7, 8 und 9 veranschaulichen ein zweites Ausführungsbeispiel eines Kühltisches nach der Erfindung. Der Tischkorpus 37 ist getrennt von der Tischplatte 38 ausgebildet und umfaßt das Kühlaggregatfach 8, vier Kühlfächer 39, 40 sowie eine oberhalb der Kühlfächer angeordnete Wanne 41. Das Kühlfach 39 nimmt ein Schubfach 42 auf, während die Kühlfächer 40 mit Türen 43, 44, 45 versehen sind.7, 8 and 9 illustrate a second embodiment of a cooling table according to the invention. The table body 37 is formed separately from the table top 38 and comprises the cooling unit compartment 8, four cooling compartments 39, 40 and a trough 41 arranged above the cooling compartments. The cooling compartment 39 accommodates a drawer 42, while the cooling compartments 40 have doors 43, 44, 45 are provided.

Die Wanne 41 ist von einem Kühlluftraum 46 aufgenommen und wird von der Kühlluft allseitig umströmt. Die Wanne 41 ist an ihrem dem Kühlaggregat benachbarten Längsende mit Luftaustrittsöffnungen 47 und an ihrem gegenüberliegenden Längsende mit Luftaustrittsöffnungen 48 versehen, so daß das Wanneninnere auch in Längsrichtung von der Kühlluft durchströmt wird. Unterhalb des Wannenbodens 49 ist oberhalb der Kühlfächer 39, 40 ein Flachkanal 50 für den Kühlluftstrom vorgesehen, von dem aus die Kühlluft - wie beim zuvor beschriebenen Ausführungsbeispiel - durch obere Luftaustrittsöffnungen 51 in die Kühlfächer einströmt, von wo aus die Kühlluft durch untere Luftaustrittsöffnungen 52 der Kühlfächer zum Kühlaggregat zurückströmt. Infolge der beschriebenen Aufteilung und Führung der Kühlluftströmung werden alle Kühlfächer und die Wanne gleichmäßig mit nur einem Kühlaggregat gekühlt.The trough 41 is received by a cooling air space 46 and the cooling air flows around it on all sides. The tub 41 is provided with air outlet openings 47 at its longitudinal end adjacent to the cooling unit and with air outlet openings 48 at its opposite longitudinal end so that the cooling air also flows through the interior of the tub in the longitudinal direction. Below the trough bottom 49, a flat duct 50 for the cooling air flow is provided above the cooling compartments 39, 40, from which the cooling air flows - as in the exemplary embodiment described above - into the cooling compartments through upper air outlet openings 51, from where the cooling air flows through lower air outlet openings 52 The cooling compartments flow back to the cooling unit. As a result of the described division and management of the cooling air flow, all cooling compartments and the trough are evenly cooled with only one cooling unit.

Die Wanne 41 ist durch eine Aussparung 53 in der Tischplatte 38 von oben her zugänglich. Sie ist durch einen teleskopartig zusammenschiebbaren Deckel 54 abgedeckt, der an seiner Rückseite um ein Scharnier 55 hochklappbar an der Tischplatte 38 angelenkt ist.The tub 41 is accessible from above through a recess 53 in the table top 38. It is covered by a telescopically collapsible cover 54 which is hinged on the rear side by a hinge 55 and is hinged to the table top 38.

Der Wannenboden 49 fällt zu einem Ablauf 56 hin ab, bei dem es sich um einen flexiblen Schlauch handeln kann. Im Ablauf ist vorteilhafterweise ein Absperrorgan 57 vorgesehen.
