Description

Die Erfindung betrifft ein Kühlmöbel mit einem Möbelkorpus, der einen Warenraum sowie Einrichtungen zum Kühlen und Umwälzen eines Kühlluftstromes enthält, wobei die Einrichtung zum Kühlen aus Lamellen aufweisenden Teilabschnitten zusammengesetzt und die Einrichtung zum Umwälzem zwischen den Teilabschnitten angeordnet ist.The invention relates to a refrigerator with a furniture body, which contains a goods room and devices for cooling and circulating a cooling air flow, the device for cooling being composed of sections having fins and the device for circulating being arranged between the sections.

Kühlmöbel der genannten Art finden insbesondere als Kühltheken oder Kühlregale in Großmärkten und Einzelhandelsgeschäften Verwendung. Der Warenraum enthält eine Ablagefläche, auf der Ware zum Verkauf präsentiert wird. Zur Kühlung der Ware wird ständig oder in Zeitintervallen ein kalter Luftstrom durch den Warenraum geleitet. Der kalte Luftstrom wird mittels einer Einrichtung zur Luftumwälzung, beispielsweise einem Radiallüfter oder Ventilator, erzeugt, der Luft aus der Umgebung oder aus dem Warenraum ansaugt und in den Warenraum fördert, wobei die Luft vor Eintritt in den Warenraum in einer Kühleinrichtung abgekühlt wird. Die Einrichtungen zum Kühlen und Umwälzen der Luft befinden sich unterhalb der Ablagefläche in dem Möbelkorpus.Refrigerated cabinets of the type mentioned are used in particular as refrigerated counters or refrigerated shelves in wholesale markets and retail stores. The goods room contains a storage area on which goods are presented for sale. To cool the goods, a cold air stream is routed through the goods room continuously or at intervals. The cold air flow is generated by means of a device for air circulation, for example a radial fan or fan, which sucks in air from the environment or from the goods room and conveys it into the goods room, the air being cooled in a cooling device before entering the goods room. The devices for cooling and circulating the air are located below the shelf in the furniture body.

Der Möbelkorpus muß auf seiner Innenseite von Zeit zu Zeit gereinigt werden, um Verunreinigungen, beispielsweise bei Fleischtheken herablaufendes Blut, zu entfernen, oder um Reinigungsflüssigkeit, die beim Reinigen der Ablagefläche herabtropft, aufzuwischen. Allerdings sind beim Reinigen des Möbelkorpus die Einbauten, die sich unterhalb der Ablagefläche befinden, nämlich die Einrichtungen zum Kühlen und Umwälzen der Kühlluft, sehr hinderlich. Da die Einbauten häufig scharfe Kanten aufweisen, kommt es überdies zu Verletzungen bei dem die Reinigungsarbeiten ausführenden Personal. Es ist aus diesem Grund bereits vorgeschlagen worden, die unter der Ablagefläche angeordnete Einrichtung zur Luftumwälzung an der Unterseite der Ablagefläche zu befestigen, so daß diese zum Reinigen beim Aufklappen der Ablagefläche aus dem Möbelkorpus herausgehoben wird (EP-A-16 402).The inside of the furniture body must be cleaned from time to time in order to remove contaminants, for example blood running down from meat counters, or to wipe off cleaning liquid which drips down when the storage area is cleaned. However, when cleaning the furniture body, the internals that are located below the storage surface, namely the devices for cooling and circulating the cooling air, are very cumbersome. Since the internals often have sharp edges, there is also injury to the personnel performing the cleaning work. For this reason, it has already been proposed to attach the device for air circulation arranged under the storage area to the underside of the storage area, so that it is lifted out of the furniture body for cleaning when the storage area is opened (EP-A-16 402).

Allerdings weist diese Konstruktion den Nachteil auf, daß die Ablagefläche wegen der an ihr hängenden Einbauten relativ stabil ausgeführt sein muß. Abgesehen davon ist die Zugriffmöglichkeit zum Boden des Möbelkorpus durch den nicht heraushebbaren Verdampfer und durch den unterhalb der Ablage nach unten ragenden Ventilator nach wie vor beschränkt.However, this construction has the disadvantage that the storage area must be made relatively stable because of the internals hanging on it. Apart from this, the accessibility to the bottom of the furniture body is still limited by the evaporator which cannot be lifted out and by the fan which projects below the shelf.

Daneben sind Konstruktionen bekannt, bei denen sich Einrichtungen zum Kühlen und Umwälzen an der Rückseite, d. h. an der dem Kunden abgewandten Seite des Kühlmöbels befinden (GB-A-2 094 460, US-A-2 660 864).In addition, constructions are known in which devices for cooling and circulation on the back, i. H. on the side of the refrigerator facing away from the customer (GB-A-2 094 460, US-A-2 660 864).

Die in der GB-A-2 094 460 beschriebene Anordnung der Einrichtungen zum Kühlen und Umwälzen weist jedoch den Nachteil auf, daß der Warenraum nach hinten erheblich verkürzt wird.However, the arrangement of the cooling and circulating devices described in GB-A-2 094 460 has the disadvantage that the goods space is considerably shortened towards the rear.

Aus der US-A-2 660 864 ist ein Kühlmöbel gemäß dem Oberbegriff des Anspruchs 1 bekannt, bei dem die Einrichtung zum Kühlen, die sich an der Rückseite des Möbels befindet, aus Teilabschnitten zusammengesetzt und die Einrichtung zum Umwälzen zwischen diesen Teilabschnitten angeordnet ist.From US-A-2 660 864 a refrigerator is known according to the preamble of claim 1, in which the device for cooling, which is located on the back of the furniture, is composed of sections and the device for circulation is arranged between these sections.

Diese Konstruktion enthält jedoch Einrichtungen zum Kühlen unterhalb der Ablagefläche und weist dadurch den Nachteil auf, daß die Reinigung des Kühlmöbels schwierig ist.However, this construction contains means for cooling below the shelf and has the disadvantage that cleaning the refrigerator is difficult.

Der Erfindung liegt daher die Aufgabe zugrunde, ein Kühlmöbel der eingangs genannten Art zu entwickeln, bei dem der Möbelkorpus leicht zu reinigen und das Warenraumvolumen zugleich vergrößert ist.The invention is therefore based on the object of developing a refrigerator of the type mentioned, in which the furniture body is easy to clean and the volume of the goods space is increased at the same time.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Einrichtungen zum Kühlen und Umwälzen ausschließlich an der Rückseite des Warenraums angeordnet sind, daß die Einrichtung zum Kühlen auf der Abluftseite der Einrichtung zum Umwälzen im Kühlluftstrom angeordnet ist, daß die Einrichtung zum Umwälzen in einem durch eime an der Rückseite des Warenraums angeordnete Luftleitwand, eine obere Abdeckung sowie eine die Einrichtung zum Kühlen gegen den Warenraum verschließende Trennwand gebildeten Strömungskanal angeordnet ist, der mit einem unterhalb des Warenraums angeordneten Zuluftkanal verbunden ist, und daß die Einrichtung zum Kühlen über eine im Bereich der Einrichtung zum Umwälzen angeordnete Öffnung mit dem Strömungskanal und über eine oberhalb des Strömungskanals angeordnete Luftaustrittsöffnung mit dem Warenraum verbunden ist.This object is achieved in that the devices for cooling and circulation are arranged exclusively on the back of the goods room, that the device for cooling is arranged on the exhaust side of the device for circulating in the cooling air flow, that the device for circulating in one by one the rear of the goods room arranged air baffle, an upper cover and a flow channel closing the device for cooling against the goods room is arranged, which is connected to a supply air channel arranged below the goods room, and that the device for cooling via a in the area of the device for Circulating opening is connected to the flow channel and is connected to the goods space via an air outlet opening arranged above the flow channel.

Durch die erfindungsgemäße Anordnung der Einrichtungen zum Kühlen und Umwälzen ausschließlich an der Rückseite des Kühlmöbels ist der Möbelkorpus völlig frei von störenden Einbauten, so daß der Möbelkorpus zu Reinigungsarbeiten frei zugänglich ist.Due to the arrangement according to the invention of the devices for cooling and circulating exclusively on the back of the refrigerator, the furniture body is completely free of interfering fittings, so that the furniture body is freely accessible for cleaning work.

Die erfindungsgemäße Anord'nung der Einrichtungen zum Kühlen und Umwälzen und der Einrichtungen zur Luftleitung ermöglicht eine besonders vorteilhafte Führung der Kühlluft. Die Einrichtung zum Kühlen an der Rückseite des Kühlmöbels reicht aus, um eine ausreichende und gleichmäßige Kühlung des Warenraums zu gewährleisten. Darüber hinaus ergibt sich die Möglichkeit, die Ablagefläche besonders tief anzuord- nen. Im Zusammenhang mit der platzsparenden Anordnung der Einrichtung zum Umwälzen zwischen den Teilabschnitten der Einrichtung zum Kühlen kann ein besonders großes Warenvolumen angeboten werden.The arrangement according to the invention of the devices for cooling and circulation and of the devices for air conduction enables a particularly advantageous guidance of the cooling air. The cooling device on the back of the refrigerator is sufficient to ensure adequate and uniform cooling of the goods area. Moreover, there is the possibility anzuord the shelf especially deep - nen. In connection with the space-saving arrangement of the device for circulating between the sections of the device for cooling, a particularly large volume of goods can be offered.

Es erweist sich als zweckmäßig, wenn die Einrichtung zum Kühlen in ihrem oberen und unteren Bereich jeweils Durchströmöffnungen für Kühlluft aufweist und an ihren Seiten verschlossen ist. Diese Anordnung bedingt eine senkrechte Durchströmung der Einrichtung zum Kühlen durch den Kühlluftstrom. Der Kühlluftstrom tritt über die Luftaustrittsöffnung, die oberhalb des Strömungskanals angeordnet ist, in den Waremraum ein.It proves to be expedient if the device for cooling has flow openings for cooling air in its upper and lower region and is closed on its sides. This arrangement requires the cooling air flow to flow perpendicularly through the cooling device. The cooling air flow enters through the air outlet opening, which is arranged above the flow channel Warem room one.

Es erweist sich als zweckmäßig, wenn, wie weiter vorgeschlagen, der die Einrichtung zum Umwälzen enthaltende Zwischenraum an den Seiten und oben verschlossen und zur Unterseite des Einrichtung zum Kühlen hin offen ist.It proves to be expedient if, as further proposed, the intermediate space containing the device for circulation is closed on the sides and at the top and is open towards the underside of the device for cooling.

Gemäß einer bevorzugten Ausgestaltung des erfindungsgemäßen Kühlmöbels sind die Einrichtungen zum Umwälzen und Kühlen unterhalb einer Arbeitsplatte für Verkaufspersonal angeordnet.According to a preferred embodiment of the refrigerated cabinet according to the invention, the devices for circulating and cooling are arranged below a worktop for sales personnel.

Nach einem weiteren Erfindungsmerkmal ist als Einrichtung zum Umwälzen ein Ventilator vorgesehen.According to a further feature of the invention, a fan is provided as the device for circulating.

Die Erfindung wird anhand von schematisch dargestellten Ausführungsbeispielen näher erläutert.The invention is explained in more detail with the aid of schematically illustrated exemplary embodiments.

Hierbei zeigen:

  • Figur 1 eine erfindungsgemäße Kühltheke im Querschnitt,
  • Fig. 2 u. 3 sowie 4 u. 5 zwei Ausführungsformen des Erfindungsgegenstandes, jeweils im Quer-und im Längsschnitt.
Here show:
  • FIG. 1 shows a refrigerated counter according to the invention in cross section,
  • Fig. 2 u. 3 and 4 u. 5 shows two embodiments of the subject matter of the invention, each in cross-section and in longitudinal section.

Die Kühltheke gemäß Figur 1 enthält auf einem Sockel 1 einen Möbelkorpus 2 sowie einen Aufsatz 3. Der Aufsatz 3 weist auf der dem Käufer zugewandten Seite eine Frontscheibe 4 auf. An der Rückseite der Kühltheke befindet sich eine Arbeitsplatte 5 für das Verkaufspersonal.The refrigerated counter according to FIG. 1 contains a furniture body 2 and an attachment 3 on a base 1. The attachment 3 has a front pane 4 on the side facing the buyer. At the rear of the refrigerated counter there is a worktop 5 for the sales staff.

In der von dem Möbelkorpus 2 gebildeten Wanne ist eine Ablagefläche 6 eingelegt, die in Verbindung mit einer rückwärtigen Luftleitwand 7 und einem Frontgitter 8 einen Warenraum 9 bildet, in dem Ware zum Verkauf angeboten wird. Die Kühltheke wird beispielsweise zum Anbieten von Fleischund Wurstwaren, Käse, Salaten, Feinkost usw. eingesetzt.In the tub formed by the furniture body 2, a storage surface 6 is inserted, which, in conjunction with a rear air baffle 7 and a front grille 8, forms a goods space 9 in which goods are offered for sale. The refrigerated counter is used, for example, to offer meat and sausage products, cheese, salads, delicatessen, etc.

An der Rückseite des Warenraumes 9 befindet sich ein Verdampfer 10 zum Kühlen und ein Ventilator 11 zum Umwälzen von Kühlluft. Der Ventilator 11 ist, wie aus den Figuren 3 und 5 deutlich hervorgeht, in einen Zwischenraum des Verdampfers 10 eingesetzt, so daß sein vorderer Rand annähernd bündig mit dem vorderen Rand des Verdampfers 10 abschließt. Auf diese Weise ist der Platzbedarf von Verdampfer und Ventilator minimal.At the rear of the goods room 9 there is an evaporator 10 for cooling and a fan 11 for circulating cooling air. The fan 11 is, as can be clearly seen from FIGS. 3 and 5, inserted in an intermediate space of the evaporator 10, so that its front edge is approximately flush with the front edge of the evaporator 10. In this way, the space required for the evaporator and fan is minimal.

Zwischen Verdampfer 10 und Ventilator 11 ist eine Trennwand 12 vorgesehen, die im Bereich des Ventilators 12 eine Öffnung aufweist. Der den Ventilator 11 enthaltende Luftschacht ist oben durch eine Abdeckung 13 verschlossen, während er nach unten in offener Verbindung mit einem zwischen der Ablagefläche 6 und dem Möbelkorpus 2 gebildeten Luftströmungsweg steht. Der Verdampfer 10 weist in seinem oberen und unteren Bereich jeweils Durchströmungsöffnungen für Luft auf. Im Bereich der Luftaustrittsöffnungen befindet sich eine Öffnung 14 in den Warenraum.A partition 12 is provided between the evaporator 10 and the fan 11 and has an opening in the area of the fan 12. The air duct containing the fan 11 is closed at the top by a cover 13, while at the bottom it is openly connected to an air flow path formed between the storage surface 6 and the furniture body 2. The evaporator 10 has flow openings for air in its upper and lower region. In the area of the air outlet openings there is an opening 14 in the goods area.

Die Luftführung in dem Kühlmöbel wird durch Pfeile 15 veranschaulicht. Genauere Einzelheiten der Luftführung sind den Figuren 2 bis 5 zu entnehmen.The air flow in the refrigerator is illustrated by arrows 15. More precise details of the air flow can be found in FIGS. 2 to 5.

Die Figuren 2 und 3 sowie 4 und 5 zeigen zweierlei Ausführungsformen des Verdampfers 10. Bei beiden Darstellungen sind jeweils zwei Ventilatoren 11 vorgesehen, es könnte je nach Bedarf ebensogut auch nur ein Ventilator oder eine größere Anzahl Ventilatoren vorgesehen sein.FIGS. 2 and 3 as well as 4 and 5 show two different embodiments of the evaporator 10. In both representations, two fans 11 are provided in each case, depending on requirements, just one fan or a larger number of fans could also be provided.

Der Verdampfer gemäß Figur 2 und 3 enthält Kühlrohre 16, in denen ein Kühlmittel geführt ist. Quer zu den Kühlrohren 16 sind Lamellen 17 angeordnet. Die Lamellen sind an zwei Stellen unterbrochen, so daß der Verdampfer drei Teilabschnitte 10a, 10b, 10c aufweist. Die Zwischenräume 18, 19, die zwischen den Teilabschnitten 10a, 10b, 10c gebildet sind, sind an den Seiten dicht abgeschottet. In die Zwischenräume 18, 19 sind die Ventilatoren 11 eingesetzt.The evaporator according to Figures 2 and 3 contains cooling tubes 16 in which a coolant is guided. Slats 17 are arranged transversely to the cooling tubes 16. The fins are interrupted at two points, so that the evaporator has three sections 10a, 10b, 10c. The spaces 18, 19, which are formed between the sections 10a, 10b, 10c, are sealed off on the sides. The fans 11 are inserted into the spaces 18, 19.

Der Verdampfer ist an seiner Vorderseite durch die Trennwand 12 verschlossen, die nur im Bereich der Ventilatorblätter kreisförmige Öffnungen aufweist. Der Verdampfer weist somit nur an seiner Unter- und an seiner Oberseite Luftdruchtrittsöffnungen auf. Wie die Pfeile 15 zeigen, strömt die Luft von unten an die Ventilatoren 10 und wird in die Zwischenräume 18, 19 gefördert. Die Zwischenräumen sind durch die Abdeckung 13, die Trennwand 12 und die Seitenwände an den Teilabschnitten 10a, 10b, 10c der Verdampfer verschlossen, so daß der Luftstrom nach unten abgelenkt wird, von wo aus er sich über die Unterseite der Verdampfer verteilt. Der Luftstrom durchströmt die Verdampfer von unten nach oben, wobei er sich abkühlt. Der kalte Luftstrom wird anschließend in den Warenraum geleitet.The front of the evaporator is closed by the partition 12, which has circular openings only in the area of the fan blades. The evaporator thus has air passage openings only on its lower and on its upper side. As the arrows 15 show, the air flows from below to the fans 10 and is conveyed into the spaces 18, 19. The gaps are closed by the cover 13, the partition 12 and the side walls at the sections 10a, 10b, 10c of the evaporator, so that the air flow is deflected downward, from where it is distributed over the underside of the evaporator. The air flow flows through the evaporators from bottom to top, cooling down. The cold air flow is then directed into the goods room.

Die Figuren 4 und 5 unterscheiden sich von den Figuren 2 und 3 lediglich dadurch, daß anstelle eines Verdampfers mit durchgehenden Kühlrohre drei Teilabschnitte mit getrennten Kühlrohrabschnitten 20a, 20b, 20c vorgesehen sind. Die übrigen Bauteile entsprechen denjenigen der Figuren 2 und 3.Figures 4 and 5 differ from Figures 2 and 3 only in that instead of an evaporator with continuous cooling tubes three sections with separate cooling tube sections 20a, 20b, 20c are provided. The other components correspond to those in FIGS. 2 and 3.
