Description

Kältegerät mit zwei Lagerkammern  Refrigerating appliance with two storage chambers
Die vorliegende Erfindung betrifft ein Kältegerät, insbesondere ein Haushaltskältegerät, mit zwei Lagerkammern, die gekühlt werden, indem sie nacheinander von einem The present invention relates to a refrigerator, in particular a household refrigerator, with two storage chambers, which are cooled by successively from a
Kaltluftstrom durchspült werden. Da sich die Luft auf dem Weg durch die Lagerkammern erwärmt, ist die stromaufwärtige Lagerkammer stets kälter als die stromabwärtige. Eine solche Hintereinanderschaltung ermöglicht eine einfache und kostengünstige Realisierung eines Kältegeräts mit unterschiedlich temperierten Lagerkammern. Während zwischen den zwei Lagerkammern eines solchen Kältegeräts eine Cold air flow to be flushed. As the air heats up on the way through the storage chambers, the upstream storage chamber is always colder than the downstream one. Such a series connection allows a simple and cost-effective implementation of a refrigeration device with different temperature storage chambers. While between the two storage chambers of such a refrigerator a
Temperaturdifferenz von mehreren Grad durchaus erwünscht ist, sollte die Temperature difference of several degrees is quite desirable, should the
Temperaturverteilung innerhalb einer Lagerkammer möglichst homogen sein. Dieses Ziel ist jedoch nicht ohne weiteres zu erreichen. Wenn man die kalte über der warmen Lagerkammer platziert und einen Übertritt von Luft zum Beispiel durch einen Spalt zwischen einer gemeinsamen Tür der beiden Lagerkammern und einer sich im Korpus zwischen den Lagerkammern erstreckenden horizontalen Trennwand zulässt, dann ist es ausgerechnet die kälteste Luft, die sich am Boden der kalten Lagerkammer sammelt und von dort zur wärmeren hin abfließt, so dass die Temperaturdifferenz zwischen den Kammern eher gering ausfällt. Auch im unteren Fach neigt die zugeströmte Kaltluft dazu, sich am Boden zu sammeln, so dass in beiden Fächern jeweils im oberen Bereich, insbesondere in der Nähe der Rückwand, der Luftaustausch gering ist, so dass sich dort deutlich höhere Temperaturen als in Bodennähe einstellen können. Temperature distribution within a storage chamber as homogeneous as possible. However, this goal is not easy to achieve. If one places the cold over the warm storage chamber and allows passage of air through, for example, a gap between a common door of the two storage chambers and a horizontal partition wall extending in the body between the storage chambers, then it is just the coldest air flowing on the Collect the bottom of the cold storage chamber and from there to the warmer flows out, so that the temperature difference between the chambers rather low. Also in the lower compartment, the inflowing cold air tends to collect on the ground, so that in both compartments each in the upper area, in particular near the rear wall, the air exchange is low, so that there can set much higher temperatures than at ground level ,
Platziert man die wärmere Lagerkammer zuoberst, dann kann durch einen Spalt zwischen Tür und Trennwand relativ warme Luft aus der kalten unteren Lagerkammer in die obere abfließen. Dies begünstigt sowohl eine ausreichende Temperaturdifferenz zwischen den Lagerkammern als auch eine gleichmäßige Durchspülung der unteren Lagerkammer. In der oberen Lagerkammer ergibt sich jedoch ein Problem dadurch, dass üblicherweise an der Tür montierte Türabsteller die zwischen Tür und Trennwand aufsteigende Luft zur Rückwand der Lagerkammer hin ablenken. Dies kann zur Folge haben, dass, wenn die obere Lagerkammer durch Fachböden in mehrere Fächer unterteilt ist, nur das unterste Fach auf seiner gesamten Tiefe von der am Türabsteller abgelenkten Luft durchspült wird, die darüberliegenden Fächer jedoch nicht mehr. Placing the warmer storage chamber at the top, then through a gap between the door and partition relatively warm air can flow from the cold lower storage chamber into the upper. This promotes both a sufficient temperature difference between the storage chambers as well as a uniform flushing of the lower storage chamber. In the upper storage chamber, however, there is a problem in that usually mounted on the door door racks divert the ascending air between the door and partition wall to the rear wall of the storage chamber. As a result, if the upper storage compartment is divided into multiple compartments by shelves, only the lowest compartment is possible The entire depth of the compartment is flushed with the air deflected at the door compartment, but the overlying compartments are no longer flushed.
Aufgabe der Erfindung ist daher, ein Kältegerät mit einer oberen und einer unteren Lagerkammer anzugeben, bei dem eine befriedigend homogene Temperaturverteilung bzw. eine gleichmäßige Durchspülung mit Kaltluft in der oberen Lagerkammer auf einfache Weise erreichbar ist. The object of the invention is therefore to provide a refrigeration device with an upper and a lower storage chamber, in which a satisfactorily homogeneous temperature distribution or a uniform flushing with cold air in the upper storage chamber can be achieved in a simple manner.
Die Aufgabe wird gelöst, in dem bei einem Kältegerät, insbesondere bei einem The problem is solved in which in a refrigeration device, in particular at a
Haushaltskältegerät, mit einem Korpus und einer Tür, die eine obere und eine untere Lagerkammer umschließen, wobei ein Luftdurchgang zwischen den Lagerkammern einen Einlass in der unteren Lagerkammer und einen Auslass in einen unteren Bereich der oberen Lagerkammer aufweist und ein Luftauslass der oberen Lagerkammer in einem oberen Bereich der selben vorgesehen ist, der Luftdurchgang sich in der Tür erstreckt und wenigsten einen an der Tür montierten, in die obere Lagerkammer eingreifenden A household refrigerator, comprising a body and a door enclosing an upper and a lower storage chamber, wherein an air passage between the storage chambers has an inlet in the lower storage chamber and an outlet in a lower region of the upper storage chamber and an air outlet of the upper storage chamber in an upper The same is provided, the air passage extends in the door and at least one mounted on the door, engaging in the upper storage chamber
Türabsteller überbrückt. Dieser Luftdurchgang erlaubt es, eine Ablenkung der in die obere Lagerkammer eindringenden Luft an der Unterseite des Türabstellers zu vermeiden, so dass ein maßgeblicher Teil dieses Luftstroms in Türnähe in der oberen Lagerkammer aufsteigen kann. Oberer und unterer Bereich der oberen Lagerkammer sind vorzugsweise durch wenigstens einer Auflage für einen Fachboden voneinander getrennt. Eine solche Ablage kann in herkömmlicher Weise an Seitenwänden des Korpus abgeformt sein. Door racks bridged. This passage of air makes it possible to avoid a deflection of the air entering the upper storage chamber at the bottom of the door compartment, so that a significant part of this air flow near the door in the upper storage chamber can ascend. Upper and lower areas of the upper storage chamber are preferably separated from each other by at least one support for a shelf. Such a tray may be formed in a conventional manner on side walls of the body.
Wenn zwischen unterem und oberem Bereich der oberen Lagerkammer ein Fachboden angeordnet ist, dann sollte dieser sowohl von der Tür in geschlossener Stellung als auch von einer Rückwand des Korpus jeweils durch einen Spalt beabstandet sein. Indem die vordere Kante eines solchen Fachbodens in den an der Tür der oberen Lagerkammer aufsteigenden Luftstrom eingreift, lenkt der Fachboden einen Teil des Luftstroms in ein unter ihm liegendes Fach der oberen Lagerkammer ab. Dieser abgetrennte Teil durchspült das Fach auf seiner gesamten Tiefe und steigt schließlich durch den Spalt zwischen Fachboden und Rückwand zum Luftauslass der oberen Lagerkammer hin auf. Der Teil des Luftstroms, der zwischen der Vorderkante des Fachbodens und der Tür aufsteigt, kann an einem zweiten Fachboden nochmals unterteilt werden, um ein zwischen den Fachböden liegendes Fach zu durchspülen, oder er wird an einer Decke der oberen Lagerkammer zum Auslass hin abgelenkt. If a shelf is arranged between the lower and upper areas of the upper storage chamber, then this should be spaced from the door in the closed position as well as from a rear wall of the body each by a gap. By engaging the leading edge of such shelf into the airflow ascending the door of the upper storage compartment, the shelf deflects a portion of the airflow into a compartment of the upper storage compartment below it. This separated part rinses through the compartment at its entire depth and finally rises through the gap between the shelf and the rear wall to the air outlet of the upper storage chamber. The part of the airflow that rises between the front edge of the shelf and the door can be divided again on a second shelf to one flushing through the compartment between the shelves, or it will be deflected to the outlet on a ceiling of the upper storage compartment.
Der Luftauslass der oberen Lagerkammer befindet sich zweckmäßigerweise in einer von Decke und Rückwand der oberen Lagerkammer gebildeten Ecke. The air outlet of the upper storage chamber is suitably located in a corner formed by the ceiling and rear wall of the upper storage chamber.
Um eine gleichmäßige Verteilung des Luftstroms über die Breite der oberen Lagerkammer hinweg zu gewährleisten, ist es wünschenswert, auch den Durchgang breit zu machen. Dessen Breite sollte wenigstens die halbe Breite, vorzugsweise wenigstens dreiviertel der Breite dieses Türabstellers ausmachen. In order to ensure a uniform distribution of the air flow across the width of the upper storage chamber, it is desirable to also make the passage wide. Its width should make up at least half the width, preferably at least three quarters of the width of this door compartment.
Die Tür kann in fachüblicher Weise eine Wärmedämmschicht und eine sich zwischen der Wärmedämmsicht und den Lagerkammern erstreckende Innenwand umfassen. Die Innenwand kann dann zweckmäßigerweise eine Aussparung aufweisen, durch die der Luftdurchgang verläuft. The door may include a thermal barrier coating and an inner wall extending between the thermal insulation panel and the storage chambers in the usual way. The inner wall can then expediently have a recess through which the air passage extends.
Im einfachsten Fall kann eine Wand des Türabstellers auch den Durchgang begrenzen. Bevorzugt ist jedoch, dass die Aussparung teilweise von einer Wandplatte überdeckt ist. In the simplest case, a wall of the door compartment can also limit the passage. However, it is preferred that the recess is partially covered by a wall plate.
Eine solche Wandplatte kann in ähnlicher Weise wie der Türabsteller an Nocken der Innenwand aufgehängt sein. Such a wall plate can be hung on cams of the inner wall in a similar manner as the door racks.
Die Wandplatte kann so geformt sein, dass sie und eine sich zwischen den The wall plate can be shaped so that it and one between the
Lagerkammern erstreckende Trennwand des Korpus bei geschlossener Tür einen Spalt begrenzen, dessen Querschnitt kleiner ist als der des Luftdurchgangs. So kann mit Hilfe der Trennwand erzwungen werden, dass von der unteren zur oberen Lagerkammer überströmende Luft zumindest überwiegend den Luftdurchgang passiert. Bearing chambers extending partition of the body with closed door limit a gap whose cross-section is smaller than that of the air passage. Thus, it can be forced with the help of the partition that at least predominantly passes through the air passage from the lower air to the upper storage chamber.
Insbesondere kann die Wandplatte zu diesem Zweck eine schräg nach unten auf die Trennwand zulaufende Schürze umfassen. In particular, the wall plate may for this purpose comprise an apron tapering downwards onto the dividing wall.
Um den Querschnitt des Spalts zu minimieren, erstreckt sich die Schürze vorzugsweise über die gesamte Breite der Trennwand. Vom Luftauslass der oberen Lagerkammer aus kann ein Ansaugkanal in einer Rückwand des Korpus abwärts zu einer Verdampferkammer verlaufen. In order to minimize the cross-section of the gap, the skirt preferably extends over the entire width of the dividing wall. From the air outlet of the upper storage chamber, a suction channel in a rear wall of the body can run down to an evaporator chamber.
Eine solche Verdampferkammer kann insbesondere in Höhe der unteren Lagerkammer angeordnet sein. Such an evaporator chamber can be arranged in particular at the level of the lower storage chamber.

The refrigeration device comprises in a customary manner a body 1 and an attached to the body door 2, which define an interior. A horizontal partition 3 divides the interior into a
Normalkühlfach fungierende obere Lagerkammer 4 und einen unteren Teil, der seinerseits durch eine vertikale Trennwand 5 in eine untere Lagerkammer 6 zwischen der Tür 2 und der Trennwand 5 und eine Verdampferkammer 7 zwischen der Trennwand 5 und einer Rückwand 8 des Korpus gegliedert ist. Normal cooling compartment functioning upper storage chamber 4 and a lower part, which in turn is divided by a vertical partition 5 in a lower storage chamber 6 between the door 2 and the partition wall 5 and an evaporator chamber 7 between the partition wall 5 and a rear wall 8 of the carcass.
An einem Durchgang 9 der Trennwand 5 ist ein Ventilator 10 angeordnet, um Luft durch einen in der Verdampferkammer 7 untergebrachten Verdampfer 1 1 hindurchzusaugen und die so abgekühlte Luft in die untere Lagerkammer 6 einzublasen. An einer vorderen oberen Ecke der unteren Lagerkammer 6 ist ein Luftdurchgang 12 gebildet, der zur oberen Lagerkammer 4 führt. Die obere Lagerkammer 4 hat wiederum einen Luftauslass 13 benachbart zu einer von Rückwand 8 und Decke 14 des Korpus 1 gebildeten Ecke. Von diesem Luftauslass 13 aus erstreckt sich ein Ansaugkanal 15 an der Rückwand 8 abwärts, zurück zur Verdampferkammer 7. Der Ansaugkanal 15 kann, wie in der Figur angedeutet, durch eine flache, in die Rückwand 8 eingetiefte Rille und eine die Rille überdeckende Wandplatte 16 gebildet sein. At a passage 9 of the partition wall 5, a fan 10 is arranged to suck air through an accommodated in the evaporator chamber 7 evaporator 1 1 and to inject the thus cooled air into the lower storage chamber 6. At a front upper corner of the lower storage chamber 6, an air passage 12 is formed, which leads to the upper storage chamber 4. The upper storage chamber 4 in turn has an air outlet 13 adjacent to a corner formed by the rear wall 8 and ceiling 14 of the body 1. From this air outlet 13, an intake passage 15 extends down the rear wall 8, back to the evaporator chamber 7. The intake passage 15 can, as indicated in the figure, formed by a flat, recessed in the rear wall 8 groove and a groove covering the wall plate 16 be.
In fachüblicher Weise sind an den Seitenwänden der oberen Lagerkammer 4 in unterschiedlichen Höhen Auflagen 17 ausgeformt, von denen manche einen Fachboden 18 tragen. Zwischen den Hinterkanten der Fachböden 18 und der Rückwand 8 bzw. der Wandplatte 16 ist jeweils ein Spalt 19 freigehalten. In entsprechender Weise sind die Vorderkanten der Fachböden 18 von einer vertikalen Ebene, die durch der Rückwand 8 zugewandte Seitenwände 20 von Türabstellern 21 , 22 verläuft, durch einen Spalt 23 getrennt. In a customary manner supports 17 are formed on the side walls of the upper storage chamber 4 at different heights, some of which carry a shelf 18. Between the trailing edges of the shelves 18 and the rear wall 8 and the wall plate 16 each have a gap 19 is kept free. In a corresponding manner, the front edges of the shelves 18 are separated from one another by a gap 23 from a vertical plane which extends through the rear walls 8 facing side walls 20 of door racks 21, 22.
Die Tür 2 ist in fachüblicher Weise aufgebaut aus einer zum Beispiel aus Blech geformten festen Außenwand 24, einer aus Kunststoff-Flachmaterial tiefgezogenen Innenwand 25 und einer den Zwischenraum zwischen Außen- und Innenwand ausfüllenden The door 2 is constructed in a customary manner from a solid outer wall 24 formed, for example, from sheet metal, an inner wall 25 which is deep-drawn from plastic flat material and which fills the gap between the outer and inner wall

Die Innenwand 25 ist in Fig. 2 in einer perspektivischen Ansicht gezeigt. In einem unteren Bereich der Innenwand 25 ist ein flacher Vorsprung 27 geformt, dessen Breite und Höhe im Wesentlichen denen der unteren Lagerkammer 6 entsprechen, und der bei The inner wall 25 is shown in Fig. 2 in a perspective view. In a lower portion of the inner wall 25, a flat projection 27 is formed, the width and height of which substantially correspond to those of the lower storage chamber 6, and at
geschlossener Tür 2 in die Lagerkammer 6 eingreift. An den Vorsprung 27 schließt sich nach oben eine flache Vertiefung 28 an, die sich, die Trennwand 3 überbrückend, teilweise in Höhe der unteren Lagerkammer 6, teilweise in Höhe der oberen Lagerkammer 4 erstreckt. In ihrem in die obere Lagerkammer 4 eingreifenden Teil ist die Vertiefung 28 flankiert von Holmen 29, die sich im Wesentlichen über die gesamte Höhe der oberen Lagerkammer 4 erstrecken und an ihren einander zugewandten Flanken in fachüblicher Weise Nocken 30 tragen, die vorgesehen sind, um daran die Türabsteller 21 , 22 aufzuhängen. closed door 2 engages in the storage chamber 6. The projection 27 is adjoined at the top by a shallow indentation 28, which, bridging the partition wall 3, partially extends at the level of the lower storage chamber 6, partly at the level of the upper storage chamber 4. In its engaging in the upper bearing chamber 4 part of the recess 28 is flanked by bars 29 which extend substantially over the entire height of the upper bearing chamber 4 and carry at their facing flanks in a conventional manner cams 30 which are provided to it hang the door racks 21, 22.
Das unterste Paar dieser Nocken 30 befindet sich in Höhe der Vertiefung 28. Die Breite der Vertiefung 28 ist geringfügig kleiner als der Abstand zwischen den einander zugewandten Flanken der Holme 29, so dass zwischen diesen Flanken und The lowest pair of these cams 30 is at the level of the recess 28. The width of the recess 28 is slightly smaller than the distance between the each other facing flanks of the spars 29, so that between these flanks and
Seitenwänden 31 auf beiden Seiten der Vertiefung 28 ein schmaler nicht vertiefter Streifen 32 der Wandfläche bestehen bleibt, der zur Abstützung einer türseitigen  Side walls 31 on both sides of the recess 28 remains a narrow non-recessed strip 32 of the wall surface remains, which is used to support a door-side
Seitenwand des an dem untersten Paar Nocken 30 aufgehängten Türabstellers 21 (siehe Fig. 1 ) dient. Weitere Nocken 33 sind an den beiden Seitenwänden 31 der Vertiefung 28 abgeformt. Sidewall of the bottom of the pair of cams 30 suspended door compartment 21 (see Fig. 1) is used. Further cams 33 are formed on the two side walls 31 of the recess 28.
Diese letzteren Nocken 33 dienen zur Verankerung einer in Fig. 3 in perspektivischer Ansicht gezeigten Wandplatte 34. Die Wandplatte 34 umfasst eine zentrale Planfläche 35, von deren Rückseite an ihren seitlichen Rändern zwei Stege 36 abstehen. Nur einer dieser Stege 36 ist in Fig. 3 sichtbar. Die Stege 36 sind mit zu den Nocken 33 These latter cams 33 serve to anchor a wall plate 34 shown in a perspective view in FIG. 3. The wall plate 34 comprises a central plane surface 35, from whose rear side two webs 36 protrude at their lateral edges. Only one of these webs 36 is visible in Fig. 3. The webs 36 are to the cam 33rd
komplementären Kerben 37 versehen, die es erlauben, die Wandplatte 34 in die provided complementary notches 37, which allow the wall plate 34 in the
Vertiefung 28 so einzuhängen, dass die Wandplatte 34 den Luftdurchgang 12 zum Korpus 1 hin begrenzt und die Planfläche 35 mit den zur Vertiefung 28 seitlich benachbarten Streifen 32 der Innenwand 25 bündig ist. Mount recess 28 so that the wall plate 34, the air passage 12 is limited to the body 1 out and the flat surface 35 with the laterally adjacent to the recess 28 strips 32 of the inner wall 25 is flush.
Fig. 4 zeigt die Innenwand 25 der Tür 2 mit der in die Vertiefung 28 eingehängten Fig. 4 shows the inner wall 25 of the door 2 with the hinged into the recess 28
Wandplatte 34. Ein Einlass 38 des Luftdurchgangs 12 ist nach oben begrenzt durch eine Schürze 40, die sich von der Unterkante der Planfläche 35 aus schräg abwärts ins Innere des Korpus 1 hinein erstreckt und in geschlossener Stellung der Tür 2, wie in Fig. 1 gezeigt, in geringem Abstand von der Vorderkante der Trennwand 3 endet. Die Schürze 40 ist breiter als die Planfläche 35 und greift seitwärts von der Vertiefung 28 auf die seitlichen Streifen 32 aus. Eine Oberkante der Schürze 40 liegt an den Streifen 32 an; eine Unterkante begrenzt in geschlossener Stellung der Tür 2 zusammen mit der Wall plate 34. An inlet 38 of the air passage 12 is bounded at the top by a skirt 40 which extends obliquely downward from the lower edge of the flat surface 35 inside the body 1 and in the closed position of the door 2, as shown in Fig. 1 , ends at a small distance from the front edge of the partition wall 3. The skirt 40 is wider than the flat surface 35 and extends laterally from the recess 28 on the side strips 32. An upper edge of the skirt 40 abuts the strip 32; a lower edge limited in the closed position of the door 2 together with the
Vorderkante der Trennwand 3 einen Spalt 41 (siehe Fig. 1 ), dessen Querschnittsfläche allerdings erheblich geringer ist als die der Vertiefung 28, so dass die Kaltluft, die bei laufendem Ventilator 10 von der unteren Lagerkammer 6 in die obere Lagerkammer 4 überströmt, zu einem überwiegenden Teil den Weg durch den Luftdurchgang 12 nimmt. Front edge of the partition wall 3 a gap 41 (see Fig. 1), the cross-sectional area, however, is considerably less than that of the recess 28, so that the cold air, which flows with the fan 10 from the lower storage chamber 6 into the upper storage chamber 4, to a predominantly takes the path through the air passage 12.
Der freie Querschnitt des Spalts 41 könnte auch verschwinden, insbesondere wenn die Schürze 40 elastisch und in Kontakt mit der Trennwand 3 leicht genug verformbar ist, um das Schließen der Tür 2 nicht zu behindern. The free cross-section of the gap 41 could also disappear, especially if the skirt 40 is resilient enough and deformable in contact with the partition 3 slightly enough to not hinder the closing of the door 2.
Im hier betrachteten Fall ist ein nicht verschwindender Querschnitt des Spalts 41 durchaus erwünscht, um einen Teil der in die obere Lagerkammer 4 fließenden Luft durch den Spalt 41 hindurchtreten und von unten gegen den Türabsteller 21 stoßen zu lassen und so diese Luft im Wesentlichen horizontal in Richtung der Rückwand 8 abzulenken. So durchströmt diese Luft ein von der Trennwand 3 und dem untersten Fachboden 18 begrenztes unterstes Fach 42 der oberen Lagerkammer 4 bis zur Rückwand 8, um dann an dieser durch die Spalte 19 hindurch bis zum Luftauslass 13 anzusteigen. In the case considered here, a non-vanishing cross-section of the gap 41 is quite desirable to a part of the air flowing into the upper storage chamber 4 through Passing the gap 41 and to let push against the door racks 21 from below and thus deflect this air substantially horizontally in the direction of the rear wall 8. Thus, this air flows through one of the partition wall 3 and the bottom shelf 18 limited bottom shelf 42 of the upper storage chamber 4 to the rear wall 8, then to rise at this through the column 19 through to the air outlet 13.
Der überwiegende Teil der in die obere Lagerkammer 4 zufließenden Luft durchläuft den Luftdurchgang 12 und gelangt an dessen Auslass 39 oberhalb des Türabstellers 21 und im Wesentlichen auch oberhalb des Fachs 42 in die obere Lagerkammer 4. Der Auslass 39 ist von dem nächsthöheren Türabsteller 22 weit genug entfernt, um eine Ablenkung der hindurchtretenden Luft in die Horizontale an der Unterseite dieses Türabstellers 22 zu vermeiden. Der über den Auslass 39 in die obere Lagerkammer 4 eintretende Luftstrom strömt hier eine Vorderkante des zweituntersten Fachbodens 18 an und teilt sich an diesem in einen Zweig, der das zweitunterste Fach 43 durchspült, um anschließend entlang der Rückwand 8 zum Luftauslass 13 aufzusteigen, und einen Zweig, der durch den Spalt 23 an der Vorderkante dieses Fachbodens 18 aufsteigt, um die darüber liegenden Fächer 44 jeweils von vorn bis hinten zu durchspülen. So wird die aus der unteren Lagerkammer 6 zuströmende Kaltluft weitgehend gleichmäßig auf sämtliche Fächer 42, 43, 44 der oberen Lagerkammer 4 verteilt, und es gibt, abgesehen vom Inneren eines Butterfachs 45, keine größeren Bereiche in der oberen Lagerkammer 4, die von der Luftzirkulation so stark abgeschnitten sind, dass sie eine deutlich höhere The majority of the air flowing into the upper storage chamber 4 passes through the air passage 12 and arrives at its outlet 39 above the door compartment 21 and substantially also above the compartment 42 in the upper storage chamber 4. The outlet 39 is far enough from the next higher door rack 22 removed in order to avoid a deflection of the air passing into the horizontal at the bottom of this door compartment 22. The airflow entering the upper storage chamber 4 via the outlet 39 flows here to a leading edge of the second lowest shelf 18 and is divided into a branch which flushes through the second bottom shelf 43, then ascending along the rear wall 8 to the air outlet 13, and a Branch rising through the gap 23 at the front edge of this shelf 18 to flush the overlying compartments 44 from front to back respectively. Thus, the cold air flowing in from the lower storage chamber 6 is largely uniformly distributed to all compartments 42, 43, 44 of the upper storage chamber 4, and apart from the interior of a butter compartment 45, there are no larger areas in the upper storage chamber 4 due to air circulation are severely cut off so that they are a much higher
Temperatur als die der durchströmtem Fächer 42, 43, 44 erreichen könnten. Temperature than that of the traversed fan 42, 43, 44 could reach.
