Description

Die Erfindung betrifft ein Kühlmöbel mit einem Möbelkorpus, der einen Warenraum sowie Einrichtungen zum Kühlen und Umwälzen eines Kühlluftstromes enthält.The invention relates to a refrigerator with a furniture body, which contains a goods room and facilities for cooling and circulating a cooling air flow.

Kühlmöbel der genanntenlArt 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 storage surface 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 Personals. 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 impurities, for example blood running down from meat counters, or to wipe up any cleaning liquid that drips down when cleaning the shelf. 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 fix 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.

Der Erfindung liegt daher die Aufgabe zugrunde, ein Kühlmöbel der eingangs genannten Art zu entwickeln, bei dem der Möbelkorpus leicht zu reinigen ist.The invention is therefore based on the object to develop a refrigerator of the type mentioned, in which the furniture body is easy to clean.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Einrichtungen zum Kühlen und Umwälzen an der Rückseite des Warenraumes angeordnet sind.This object is achieved in that the devices for cooling and circulation are arranged on the back of the goods room.

Im Gegensatz zu den bisherigen Kühlmöbeln, bei denen sich die Einrichtungen zum Kühlen und Umwälzen unter der Ablagefläche des Warenraumes befinden, wird nunmehr erfindungsgemäß vorgeschlagen, diese Einrichtungen hinter dem Warenraum unterzubringen. Hinter dem Warenraum heißt auf der dem Käufer abgewandten Seite des Kühlmöbels.In contrast to the previous refrigerated furniture, in which the devices for cooling and circulation are located under the storage surface of the goods area, it is now proposed according to the invention to accommodate these devices behind the goods area. Behind the goods room is called side of the refrigerator facing away from the buyer.

Durch den Erfindungsgegenstand ist der Möbelkorpus völlig frei von störenden Einbauten, so daß der Möbelkorpus zu Reinigungsarbeiten frei zugänglich ist. Ein weiterer Aspekt ist die Möglichkeit, die Ablagefläche tiefer als bisher anzuordnen, so daß das Warenraumvolumen vergrößert wird.Due to the subject matter of the invention, the furniture body is completely free from interfering fixtures, so that the furniture body is freely accessible for cleaning work. Another aspect is the possibility of arranging the storage area deeper than before, so that the volume of the goods space is increased.

Bei einer bevorzugten Weiterbildung des Erfindungsgegenstandes ist die Einrichtung zum Kühlen aus Lamellen aufweisenden Teilabschnitten zusammengesetzt und befindet sich die Einrichtung zum Umwälzen zwischen den Teilabschnitten.In a preferred development of the subject matter of the invention, the device for cooling is composed of sections having fins and the device for circulating is located between the sections.

Die erfindungsgemäße Anordnung der Einrichtungen zum Umwälzen und Kühlen bedingt eine Verkürzung des Warenraumes, die in vielen Fällen unerwünscht ist. Ist nun gemäß dem weiterbildenden Vorschlag die Einrichtung zum Umwälzen zwischen zwei Teilabschnitten.der Einrichtung zum Kühlen untergebracht, so befinden sich die beiden Einrichtungen im wesentlichen in einer Ebene, d.h. beide Einrichtungen beanspruchen zusammen nicht mehr Platz, als die Einrichtung zum Kühlen.The arrangement of the devices for circulating and cooling according to the invention causes a shortening of the goods space, which is undesirable in many cases. If, according to the further development proposal, the device for circulating is now housed between two sections of the device for cooling, the two devices are essentially in one plane, i.e. the two devices together do not take up more space than the cooling device.

In vorteilhafter Ausgestaltung des erfindungsgemäßen Kühlmöbels wird vorgeschlagen, daß die Einrichtung zum Kühlen auf der Abluftseite der Einrichtung zum Umwälzen im Kühlluftstrom angeorndet ist.In an advantageous embodiment of the refrigerated cabinet according to the invention it is proposed that the device for cooling is arranged on the exhaust air side of the device for circulating in the cooling air flow.

Es erweist sich als zweckmäßig, wenn, wie weiter vorgeschlagen wird, 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. Zweckmäßigerweise befindet sich oberhalb -der Einrichtung zum Kühlen eine Luftaustrittsöffnung in den Warenraum.It proves to be expedient if, as is further proposed, the cooling device 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. It is conveniently located above the cooling device an air outlet opening into the goods room.

Bei einer vorteilhaften Weiterbildung des Erfindungsgegenstandes ist die Einrichtung zum Umwälzen in einem nach unten geöffnten Strömungskanal angeordnet, der mit einem unterhalb des Warenraumes befindlichen Strömungskanal für den Kühlluftstrom in Verbindung ist.In an advantageous development of the subject matter of the invention, the device for circulating is arranged in a flow channel which is open at the bottom and which is connected to a flow channel for the cooling air flow located below the goods space.

Der Strömungskanal, der die Einrichtung zum Umwälzen enthält, ist nach vorne gegenüber dem vor der Einrichtung" zum Umwälzen befindlichen Warenraum verschlossen. Der unterhalb des Warenraums befindliche Strömungsweg ist vorzugsweise durch den Möbelkorpus einerseits und durch die Ablagefläche andererseits begrenzt.The flow channel, which contains the device for circulating, is closed towards the front from the goods room located in front of the device for circulating. The flow path below the goods room is preferably limited by the furniture body on the one hand and by the storage surface on the other.

Es erweist sich als zweckmäßig, wenn gemäß einer weiteren Ausgestaltung des Erfindungsgegenstandes der die Einrichtung zum Umwälzen enthaltende Zwischenraum an den Seiten und oben verschlossen und zur Unterseite der Einrichtung zum Kühlen hin offen ist.It proves to be expedient if, according to a further embodiment of the subject of the invention, 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.

Bei dieser Anordnung wird der Kühlluftstrom zunächst nach unten geführt und von unten nach oben durch die Kühleinrichtung geleitet. Zwei der Seitenwände können durch Verdampferlamellen derbeidseitigan den Zwischenraum angrenzenden Teilabschnitte der Einrichtung zum Kühlen gebildet sein.In this arrangement, the cooling air flow is first led downward and passed through the cooling device from bottom to top. Two of the side walls can be formed by evaporator fins of the sections of the device for cooling which adjoin the intermediate space on both sides.

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 sowie weitere Einzelheiten der Erfindung werden anhand von schematisch dargestellten Ausführungsbeispielen näher erläutert.The invention and further details of the invention are explained in more detail with reference to schematically illustrated exemplary embodiments.

Hierbei zeigen:

  • Figur 1 eine erfindungsgemäße Kühltheke im Querschnitt, Fig. 2 u. 3 zwei Ausführungsformen des Erfindungsgegensowie 4 u. 5 standes, jeweils im Quer- und im Längsschnitt.
Here show:
  • Figure 1 shows a refrigerated counter according to the invention in cross section, Fig. 2 u. 3 two embodiments of the invention as well as 4 u. 5 stands, each in cross 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 Fleisch-und 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 one containing the fan 11 Air duct 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 room.

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 i 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 gaps 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 through the cover 13, the partition 12 and the sides walls on the sections 10a, 10b, 10c of the evaporator closed, 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.
