Abstract

The refrigerator cabinet (12) contains uniformly spaced shelves (13) and a drawer (14) which rests in close proximity to the floor and back, but leaves a channel (15) for circulation of air around and under it. Another airway (28) is left between the compartments (26) and the interior cladding (24) of the door (23). The circulation (16) is driven by a fan (19) set into a niche (18) at the top of the back wall from which the three ducts (21) with lateral fins run between a partition (20) and the cold-wall evaporator (17).

Description

Die Erfindung betrifft ein Kühlgerät, insb. einen Haushalts-Kühlschrank mit einem wärmeisolierenden Gehäuse und einer daran angeschlagenen Tür, welche mit Ablagefächern zum Abstellen von Kühlgut ausgestattet ist und welche im geschlossenen Zustand zusammen mit dem Gehäuse einen Kühlraum umschließt, dessen Temperatur durch zwangsweises Umwälzen eines von einem Ventilator erzeugten und über einen Verdampfer geförderten Luftstromes wenigstens annähernd konstant gehalten ist, wobei der Luftstrom wenigstens zu einem Teil durch Luftleiteinrichtungen zur Tür hin umgelenkt ist.The invention relates to a refrigerator, in particular a household refrigerator with a heat-insulating housing and a door attached to it, which is equipped with storage compartments for storing items to be refrigerated and which, in the closed state, encloses a cooling chamber together with the housing, the temperature of which is forced by circulating one air flow generated by a fan and conveyed via an evaporator is kept at least approximately constant, the air flow being deflected at least in part by air guiding devices toward the door.

Bei Haushalts-Kühlschränken der genannten Art ist man bestrebt, die Temperaturverteilung in den einzelnen Fächern möglichst konstant auf dem bestimmungsgemäßen Niveau zu halten, um das dort eingelagerte, meist leicht verderbliche Gut über einen langen Zeitraum lagern zu können, ohne daß es dabei Qualitätseinbußen erleidet.In household refrigerators of the type mentioned, the aim is to keep the temperature distribution in the individual compartments as constant as possible at the intended level in order to be able to store the usually perishable goods stored there over a long period of time without suffering any loss in quality.

Hierzu wurde in der DE-PS 41 31 211 ein Kühlgerät vorgeschlagen, bei welchem die Luft innerhalb seines Kühlraumes durch einen Ventilator zwangsweise umgewälzt und zu ihrer Abkühlung über einen Coldwall-Verdampfer gefördert ist. Zu diesem Zweck ist die abzukühlende Kühlraumluft über die Wärmetauschfläche des Verdampfers anhand von Luftführungskanälen geführt, welche von einer Zwischenwand getragen sind und welche einerseits mit Abstand über dem Boden des Kühlraumes und andererseits an dessen Seitenwände, unmittelbar unter der Decke des Kühlraumes, im Nahbereich der Tür ihre Austrittsöffnungen aufweisen. Durch die Anordnung der Luftaustrittsöffnungen und der Luftführung innerhalb des Kühlraumes wurde zwar in diesem bereits weitestgehend eine homogene Temperaturverteilung auf dem bestimmungsgemäßen Temperaturniveau erreicht, jedoch tragen im Bereich der Türablagefächer, insb. im oberen Türablagebereich Abweichungen davon auf.For this purpose, a cooling device was proposed in DE-PS 41 31 211, in which the air inside its cooling space was forcedly circulated by a fan and conveyed to cool it down by means of a cold wall evaporator. For this purpose, the cold room air to be cooled is via the heat exchange surface of the evaporator using air duct channels led, which are supported by an intermediate wall and which have their outlet openings on the one hand at a distance above the floor of the cooling room and on the other hand on its side walls, directly under the ceiling of the cooling room, in the vicinity of the door. The arrangement of the air outlet openings and the air duct inside the cold room has largely achieved a homogeneous temperature distribution at the intended temperature level, but deviations from this are evident in the area of the door storage compartments, especially in the upper door storage area.

Der Erfindung liegt die Aufgabe zugrunde, aufbauend auf diesem Stand der Technik, mit einfachen konstruktiven Maßnahmen die Temperaturverteilung innerhalb des Kühlraumes unter Einbezug der Türablagefächer weiter zu verbessern und zu vergleichmäßigen.The object of the invention, based on this state of the art, is to further improve and to even out the temperature distribution within the cold storage space, including the door storage compartments, with simple constructive measures.

Diese Aufgabe wird gemäß der Erfindung dadurch gelöst, daß zwischen der türseitigen Längsseite der Ablagefächer und der Innenverkleidung der Tür ein Luftweg freigespart ist, durch welchen der auf die Tür zuströmende Luftstrom durchzuströmen vermag.This object is achieved in accordance with the invention in that an air path is cleared between the longitudinal side of the storage compartments on the door side and the interior paneling of the door, through which the air stream flowing to the door can flow.

Durch die erfindungsgemäße Lösung sind die Ablagefächer sowohl auf ihrer türseitigen als auch auf der dazu parallelen Längsseite von Kühlluft umströmt, wodurch das Temperaturniveau im bereich der Ablagefächer weitestgehend den des übrigen Kühlraumes angeglichen ist, so daß eine relativ gleichmäßige Temperaturverteilung innerhalb des Kühlraumes erreicht ist. Ein weiterer Vorzug ist darin zu sehen, daß je nach Kühlbedarf der Luftweg auf einfache Weise mit unterschiedlichem Durchströmungs-Querschnitt versehen werden kann, so daß eine gezielte Luftumwälzung und daraus relultierende Kühlung insb. im Bereich der höherliegenden Ablagefächer an der Tür erreicht werden kann.Due to the solution according to the invention, cooling air flows around the storage compartments both on their door side and on the longitudinal side parallel to them, as a result of which the temperature level in the storage compartments is largely matched to that of the rest of the cooling space, so that a relatively uniform temperature distribution within the cooling space is achieved. Another advantage can be seen in the fact that, depending on the cooling requirement, the air path can be provided with a different cross-section of flow in a simple manner can, so that a targeted air circulation and cooling resulting therefrom, in particular in the area of the higher storage compartments on the door, can be achieved.

Besonders intensiv und gleichmäßig wird das in den Ablagefächern der Tür abgestellte Kühlgut mit Kühlluft beaufschlagt, wenn nach einer weiteren bevorzugten Ausführungsform des Gegenstandes der Erfindung vorgesehen ist, daß der Luftweg im wesentlichen über die ganze Länge der türseitigen Längsseite der Ablagefächer angeordnet ist.The cooling goods placed in the storage compartments of the door are subjected to cooling air particularly intensively and uniformly if, according to a further preferred embodiment of the object of the invention, it is provided that the airway is arranged essentially over the entire length of the door-side long side of the storage compartments.

Entsprechend einer weiteren bevorzugten Ausführungsform des Gegenstandes der Erfindung ist vorgesehen, daß der Luftweg durch eine Beabstandung der türseitigen Längsseite der Ablagefächer zur Innenverkleidung gebildet ist.According to a further preferred embodiment of the subject matter of the invention, it is provided that the air path is formed by spacing the long side of the storage compartments on the door side from the inner lining.

Eine solche Lösung zeichnet sich dadurch aus, daß der Luftweg hinsichtlich seiner Breite auf einfache Weise nur durch eine entsprechend mit Abstand zur Innenverkleidung der Tür angeordnete Befestigungsmaßnahme für das Ablagefach in seiner momentanen Einstellposition unverstellbar festgelegt ist. Außerdem kann die Breite des Luftweges bei mehreren Haltepositionen für die Ablagefächer mit unterschiedlichen Abstand zur Innenverkleidung der Tür auf einfache Weise verändert werden.Such a solution is characterized by the fact that the width of the airway is fixed in an unadjustable manner in its current setting position only by a fastening measure for the storage compartment which is arranged at a distance from the interior paneling of the door. In addition, the width of the airway can be changed in a simple manner in the case of a plurality of holding positions for the storage compartments at different distances from the inner lining of the door.

Gemäß einer weiteren bevorzugten Ausführungsform des Gegenstandes der Erfindung ist vorgesehen, daß die Ablagefächer behälterartig mit umlaufenden Seitenwandungen ausgebildet sind.According to a further preferred embodiment of the object of the invention, it is provided that the storage compartments are designed in a container-like manner with circumferential side walls.

Der Vorzug einer solchen Lösung ist einerseits darin zu sehen, daß der Luftweg stets sicher von in den Ablagefächern abzustellendem Kühlgut freigehalten wird. Andererseits ergibt sich durch die Behälterwandungen an den Längsseiten der Ablagefächer eine relativ exakte, über die gesamte Höhe der Ablagefächer angeordnete Luftführung.On the one hand, the advantage of such a solution is that the airway is always kept clear of refrigerated goods to be placed in the storage compartments. On the other hand, the container walls on the long sides of the storage compartments result in a relatively exact air duct arranged over the entire height of the storage compartments.

Besonders günstige Ergebnisse hinsichtlich einer rechtmäßigen Temperaturverteilung über den gesamten Kühlraum ergibt sich, wenn nach einer letzten bevorzugten Ausführungsform des Gegenstandes der Erfindung vorgesehen ist, daß die Ablagefächer zu der Innenverkleidung einen Abstand von 5 mm bis 15 mm aufweisen, aber vorzugsweise in einem Abstand von 10 zur der Innenverkleidung angeordnet sind.Particularly favorable results with regard to a lawful temperature distribution over the entire cooling space are obtained if, according to a last preferred embodiment of the object of the invention, it is provided that the storage compartments are at a distance of 5 mm to 15 mm from the inner lining, but preferably at a distance of 10 are arranged for the inner lining.

Die Erfindung ist in der nachfolgenden Beschreibung anhand eines in der beigefügten Zeichnung vereinfacht dargestellten Ausführungsbeispieles erläutert.The invention is explained in the following description with reference to an embodiment shown in simplified form in the accompanying drawing.

Die einzige Figur zeigt den von einer Tür verschlossenen, mittleren Abschnitt eines als Mehrtemperaturen-Kühlschrank ausgebildeten Kühlgerätes von der Seite gesehen im Schnitt.The single figure shows a section of the central section of a cooling device designed as a multi-temperature refrigerator, which is closed by a door.

Ein als Mehrtemperaturen-Kühlschrank ausgebildetes Kühlgerät 10 weist im mittleren Abschnitt seines wärmeisolierenden Gehäuses 11 ein als Null-Grad-Fach ausgebildetes Kühlfach 12 auf. Dieses ist mit in etwa gleichen Abständen übereinander angeordneten Tragplatten 13 ausgestattet, von denen die unterste zur Belüftung des Aufnahmeraumes eines Schubkastens 14 mit geringem Abstand über dessen Öffnungsrand angeordnet ist. Der Schubkasten 14 ist mit seinem Boden zum Boden des Kühlfaches 12 und mit seiner Rückwand zur Rückwand des Kühlfaches 12 beabstandet, wodurch in diesem Bereich ein zusammenhängender Luftkanales 15 ausgebildet ist. Dieser dient in diesem Abschnitt des Kühlfaches 12 zur Führung eines Luftstromes 16, welcher zu seiner Abkühlung über einen flächenhaften Verdampfer 17 in Form eines sogenannten Coldwall-Verdampfers anhand eines überhalb diesem vorgesehenen, etwa mittig zur Rückwand des Kühlfaches 12 in einer Nische 18 angeordneten Ventilators 19 gefördert ist. Der Ventilator 19 ist hinter einer im wesentlichen die ganze Breite der Rückwand des Kühlfaches 12 einnehmenden Zwischenwand 20 angeordnet, welche im Bereich des Lüfterrades des Ventilators 19 mit einer Ansaugöffnung versehen ist, von welcher sich drei Luftkanäle 21 fächerartig nach unten erstrecken. Die Luftkanäle 21 sind seitlich von nicht dargestellten Rippen begrenzt, die auf der dem Verdampfer 17 zugewandten Rückseite der Zwischenwand 20 verlaufen und deren Höhe so bemessen ist, daß sie dem Abstand des Verdampfers 17 zur Rückseite der Zwischenwand 20 entsprechen.A cooling device 10 designed as a multi-temperature refrigerator has a cooling compartment 12 designed as a zero-degree compartment in the middle section of its heat-insulating housing 11. This is equipped with approximately equally spaced support plates 13, the lowest of which is arranged to ventilate the receiving space of a drawer 14 at a short distance above its opening edge. The drawer 14 is spaced with its bottom to the bottom of the cooling compartment 12 and with its rear wall to the rear wall of the cooling compartment 12, so that a coherent in this area Air duct 15 is formed. In this section of the cooling compartment 12, this serves to guide an air flow 16, which is used to cool it via a flat evaporator 17 in the form of a so-called cold wall evaporator using a fan 19 provided above it and arranged approximately in the middle of the rear wall of the cooling compartment 12 in a recess 18 is promoted. The fan 19 is arranged behind an intermediate wall 20 which essentially occupies the entire width of the rear wall of the cooling compartment 12 and which is provided in the region of the fan wheel of the fan 19 with an intake opening from which three air channels 21 extend downward in a fan-like manner. The air channels 21 are laterally delimited by ribs, not shown, which run on the rear side of the intermediate wall 20 facing the evaporator 17 and whose height is such that they correspond to the distance of the evaporator 17 from the rear side of the intermediate wall 20.

Von den drei Luftkanälen 21 sind die beiden außenliegenden durch eine entsprechende Krümmung der sie begrenzenden Rippen im unteren Drittel der Zwischenwand 20 nach oben umgelenkt, so daß ihre Austrittsöffnungen seitlich oben liegen, während der zwischenliegende Luftkanal 21 am unteren Rand der Zwischenwand 20, unmittelbar über dem Luftkanal 15 austritt. Die Zwischenwand 20 ist in ihrem oberen, der Decke des Kühlfaches 12 zugewandten Abschnitt mit im Nahbereich der Seitenwände des Kühlfaches 12 angeordneten Ansätzen versehen, welche als Luftführungskanäle 22 dienen. Diese sind strömungstechnisch an die Austrittsöffnungen der nach oben geführten äußeren Luftkanäle 21 angeschlossen und mit ihren Austrittsöffnungen bis in den Nahbereich der Zugangsöffnung zum Kühlfach 12 herangeführt. Die Zugangsöffnung ist mit einer am Gehäuse 11 angeschlagenen Tür 23 verschlossen, welche an ihrer dem Kühlfach 12 zugewandten Innenseite mit einer Innenverkleidung 24 ausgestattet ist, an deren umlaufenden Rändern eine Magnetdichtung 25 angeordnet ist, welche am Öffnungsrand der Zugangsöffnung zum Kühlfach 12 anliegt.Of the three air channels 21, the two outer ones are deflected upward by a corresponding curvature of the ribs delimiting them in the lower third of the intermediate wall 20, so that their outlet openings are laterally above, while the intermediate air channel 21 is located at the lower edge of the intermediate wall 20, directly above the Air duct 15 exits. In its upper section facing the ceiling of the cooling compartment 12, the intermediate wall 20 is provided with projections which are arranged in the vicinity of the side walls of the cooling compartment 12 and which serve as air guide channels 22. In terms of flow technology, these are connected to the outlet openings of the outer air ducts 21 which are directed upwards and are brought with their outlet openings into the vicinity of the access opening to the cooling compartment 12. The access opening is closed by a door 23 which is attached to the housing 11 and which on its inside facing the cooling compartment 12 is equipped with an inner lining 24, on the circumferential edges of which a magnetic seal 25 is arranged, which bears against the opening edge of the access opening to the cooling compartment 12.

Die Innenverkleidung 24 der Tür 23 ist ferner mit nicht dargestellten Haltemitteln wie beispielsweise mit Einhängenocken oder Tragleisten versehen, welche zur Abstützung oder Halterung von Ablagefächern 26 dienen. Diese sind im vorliegenden Ausführungsbeispiel behälterartig mit umlaufenden Seitenwandungen ausgebildet, wobei die der Innenverkleidung 24 zugewandte türseitige Seitenwandung 27 der Ablagefächer 26 mit Abstand zu Innenverkleidung 24 angeordnet ist, so daß zwischen der Seitenwandung 27 und der Innenverkleidung 24 ein Luftweg 28 freigespart ist. Dieser ist über die gesamte Länge der der Innenverkleidung 24 zugewandten Seitenwandung 27 der Ablagefächer 26 angeordnet und durch eine entsprechende Anordnung der Haltemittel für die Ablagefächer 26 erzeugt, so daß sich der Luftweg 28 nur aufgrund der Anbringung der Ablagefächer 26 an der Innenverkleidung 24 ergibt, ohne diese zur Ausbildung des Luftweges 28 zusätzlichen komplizierten Formgebungen unterziehen zu müssen. Der Luftweg 28 erhält durch die Ausbildung der der Innenverkleidung 24 zugewandten Längsseite der Ablagefächer als mit einer entsprechenden Höhe ausgestatteten Wandung neben der Innenverkleidung 24 als Führungselement eine gezielte zusätzliche seitliche Führung.The inner lining 24 of the door 23 is also provided with holding means, not shown, such as, for example, with hook-in cams or support strips, which serve to support or hold storage compartments 26. In the present exemplary embodiment, these are designed like containers with circumferential side walls, the door-side side wall 27 of the storage compartments 26 facing the inner lining 24 being arranged at a distance from the inner lining 24, so that an airway 28 is cleared between the side wall 27 and the inner lining 24. This is arranged over the entire length of the side wall 27 facing the inner lining 24 of the storage compartments 26 and is produced by a corresponding arrangement of the holding means for the storage compartments 26, so that the airway 28 only results from the attachment of the storage compartments 26 to the inner lining 24 without to have to undergo 28 additional complicated shapes to form the airway. By designing the long side of the storage compartments facing the inner lining 24 as a wall equipped with a corresponding height, the airway 28 is provided with a targeted additional lateral guidance in addition to the inner lining 24 as a guide element.

Für den Fall, daß die behälterartigen Ablagefächer 26 wie oftmals üblich, zwischen senkrechten Holmen gehaltert sind, die an die Innenverkleidung 24 mitangeformt sind, ergibt sich zumindest im Bereich der behälterartigen Ablagefächer 26 eine schachtartige Ausbildung für den Luftweg 28, welcher eine besonders intensive Umstromung der Ablagefächer 26 an ihrer der Tür 23 zugewandten Längsseite mit Kühlluft bewirkt.In the event that the container-like storage compartments 26 are, as is often the case, held between vertical spars which are also molded onto the inner lining 24, there is a shaft-like design for the airway 28, at least in the region of the container-like storage compartments 26 a particularly intensive flow around the storage compartments 26 on their longitudinal side facing the door 23 with cooling air.

Die Kühlluft innerhalb des Kühlfaches 12 wird vom Ventilator 19 zu seiner Abkühlung entlang der Lüftführungskanäle 21 und über die Wärmetauschfläche des Verdampfers 17 geführt. Hierbei tritt der in den äußeren Lüftführungskanälen 21 geführte Luftstrom über den an der Decke des Kühlfaches 12 im Nahbereich der Tür 23 vorgesehenen Austrittsöffnungen der Luftführungskanäle 22 aus, während der im Luftführungskanal 21 geführte Luftstrom 16 an dessen Austrittsöffnung in den Luftkanal 15 eintritt, welcher sich durch die Ausbildung und Anordnung des Schubfaches 14 bis unmittelbar unter die Ablagefächer 26 erstreckt. Am Ende des Luftkanales 15 findet eine Aufteilung des Luftstromes 16 in zwei Teilluftströme statt, von welchen einer aufgrund der Ausbildung des Luftweges 28 entlang der Innenverkleidung 24 strömt, während der andere Teilluftstrom dazu parallel auf der der Innenverkleidung 24 abgewandten Längsseite der Ablagefächer 26 entlangströmt. Durch die Einleitung des Teilluftstromes in den Luftweg 28 ergibt sich im Bereich der Ablagefächer 26, insb. in dem obersten eine an das bestimmungsgemäße Temperaturniveau des Kühlfaches 12 angepaßte Temperatur.The cooling air inside the cooling compartment 12 is guided by the fan 19 to cool it down along the ventilation guide channels 21 and over the heat exchange surface of the evaporator 17. Here, the air flow guided in the outer ventilation duct 21 exits via the outlet openings of the air duct 22 provided on the ceiling of the cooling compartment 12 in the vicinity of the door 23, while the air flow 16 guided in the air duct 21 enters the air duct 15 at its outlet opening, which passes through the design and arrangement of the drawer 14 extends immediately below the storage compartments 26. At the end of the air duct 15, the air flow 16 is divided into two partial air flows, one of which flows along the inner lining 24 due to the formation of the air path 28, while the other partial air flow flows parallel to it on the long side of the storage compartments 26 facing away from the inner lining 24. The introduction of the partial air flow into the air path 28 results in a temperature in the area of the storage compartments 26, especially in the uppermost one, which is adapted to the intended temperature level of the cooling compartment 12.

Abweichend von dem dargestellten Ausführungsbeispiel können die Ablagefächer 26 auch als Abstellebenen ausgeführt sein, welche dann beispielsweise auf Tragleisten ruhen, wobei deren der Innenverkleidung 24 zugewandte Längsseite mit Abstand zu dieser angeordnet ist, um den Luftweg 28 auszubilden. Genauso ist es auch möglich, die Ablgefächer 26 mit Aussparung zur Ausbildung des Luftweges 28 zu versehen, anstatt deren türseitige Längsseite mit Abstand zur Innenverkleidung 24 anzuordnen. Für die Ausbildung des Luftweges 28 haben sich hinsichtlich der Durchströmung mit Kühlluft gute Ergebnisse für einen Abstand von 10 mm zwischen der Innenverkleidung 24 und der Seitenwandung 27 der Ablagefächer 26 ergeben.In a departure from the exemplary embodiment shown, the storage compartments 26 can also be designed as storage levels, which then rest, for example, on support strips, the longitudinal side thereof facing the inner lining 24 being arranged at a distance from the latter in order to form the air path 28. In the same way, it is also possible to provide the storage compartments 26 with a recess for forming the airway 28, instead of arranging their longitudinal side on the door side at a distance from the inner lining 24. For the training of the airway 28 With regard to the flow of cooling air, good results have been obtained for a distance of 10 mm between the inner lining 24 and the side wall 27 of the storage compartments 26.
