Description

Die vorliegende Erfindung betrifft ein Kältegerät, insbesondere ein Haushaltskältegerät, in No-Frost-Bauweise. Kältegeräte dieses Typs sind dadurch gekennzeichnet, dass ein Verdampfer in einer von seinem Lagerfach für Kühlgut getrennten Verdampferkammer untergebracht ist und die Lagerkammer durch Luftumwälzung zwischen diesem und der Verdampferkammer kühlt. Wenn die Luftumwälzung unterbrochen ist, ist es möglich, den Verdampfer auf über 0°C zu erwärmen und so darauf niedergeschlagenen Reif zu beseitigen, ohne dass gleichzeitig Kühlgut im Lagerfach erwärmt wird.The present invention relates to a refrigerator, in particular a household refrigerator, in no-frost construction. Refrigeration appliances of this type are characterized in that an evaporator is housed in a separated from its storage compartment for refrigerated evaporator chamber and the storage chamber by air circulation between this and the evaporator chamber cools. If the air circulation is interrupted, it is possible to heat the evaporator to over 0 ° C and thus eliminate precipitate deposited thereon, without at the same time heating refrigerated goods in the storage compartment.

Üblicherweise sind Lagerfach und Verdampferkammer eines solchen Kältegeräts in einem gemeinsamen Innenbehälter von im Wesentlichen quaderförmiger Gestalt untergebracht und voneinander durch eine in dem Innenbehälter montierte Scheidewand getrennt. Wenn die Verdampferkammer in üblicher Weise unter der Decke des Innenbehälters oder vor dessen Rückwand abgetrennt wird und die Decke bzw. die Rückwand nicht komplett ausfüllt, entstehen im Lagerfach Bereiche unterschiedlicher Tiefe, die eine effiziente Nutzung erschweren. Ein No-Frost-Kältegerät dieses Typs ist aus DE 10 2005 057 157 A1 bekannt.Usually storage compartment and evaporator chamber of such a refrigerator are housed in a common inner container of substantially cuboid shape and separated from each other by a mounted in the inner container septum. If the evaporator chamber is separated in the usual way under the ceiling of the inner container or in front of the rear wall and the ceiling or the rear wall does not fill completely, arise in the storage compartment areas of different depths, which complicate efficient use. A no-frost refrigerator of this type is out DE 10 2005 057 157 A1 known.

Aufgabe der Erfindung ist, ein No-Frost-Kältegerät zu schaffen, bei dem, obwohl sich Verdampferkammer und Lagerfach einen Innenbehälter teilen, die Nutzbarkeit des Lagerfachs durch die Verdampferkammer möglichst wenig beeinträchtigt istThe object of the invention is to provide a no-frost refrigeration device in which, although evaporator chamber and storage compartment share an inner container, the usability of the storage compartment is affected by the evaporator chamber as little as possible

Die Aufgabe wird gelöst durch ein No-Frost-Kältegerät mit den Merkmalen des Anspruchs 1. Ein horizontaler Abschnitt der Scheidewand des erfindungsgemäßen No-Frost-Kältegeräts liegt mit einem nicht ausgestülpten Bereich der Decke auf gleicher Höhe. Eine höhere Anbringung der Scheidewand würde die Nutzbarkeit des Lagerfachs nicht wesentlich verbessern, da der nicht ausgestülpte Bereich der Decke den Zugriff auf eine dahinter liegende Aussparung schwierig macht, eine tiefere Anbringung des horizontalen Abschnitts würde die nutzbare Höhe in einem Teil des Lagerfachs reduzieren. Da bei einem Kältegerät mit zwei übereinander angeordneten Lagerfächern eine Isolationsschicht zwischen den zwei Lagerfächern nicht so stark zu sein braucht wie Isolationsschichten zwischen den Lagerfächern und der Umgebung, wird die Ausstülpung für den Verdampfer und somit die Verdampferkammer in einer solchen Zwischenwand untergebracht.The object is achieved by a no-frost refrigerating appliance having the features of claim 1. A horizontal section of the septum of the no-frost refrigerating appliance according to the invention lies at the same height with a non-everted region of the blanket. Higher attachment of the septum would not significantly improve the usability of the storage compartment, as the undipped portion of the ceiling makes access to a recess located behind difficult, a deeper attachment of the horizontal section would reduce the usable height in a portion of the storage compartment. Since in a refrigerator with two stacked storage compartments, an insulation layer between the two storage compartments need not be as strong as insulation layers between the storage compartments and the environment, the protuberance housed for the evaporator and thus the evaporator chamber in such a partition.

Dementsprechend ist es zweckmäßig, dass der Verdampfer vollständig in der Hinterschneidung untergebracht ist.Accordingly, it is expedient that the evaporator is completely housed in the undercut.

Um die Scheidewand zu befestigen, ist an dieser eine Vertiefung ausgebildet. Vorzugsweise erstreckt sich die Vertiefung in die Verdampferkammer und ist nach unten offen ausgebildet. Ein Stiftelement durchsetzt eine Öffnung in einer Wandpartie der Vertiefung sowie eine Öffnung in einer der Wandpartie gegenüber liegenden Seitenwand des Innenbehälters. So kann das Gewicht der Scheidewand und gegebenenfalls eines auf ihr ruhenden Verdampfers in die Seitenwände eingeleitet werden, deren Tragfähigkeit meist besser ist als die der Decke des Innenbehälters.To secure the septum, a recess is formed on this. Preferably, the recess extends into the evaporator chamber and is open at the bottom. A pin element passes through an opening in a wall portion of the recess and an opening in a wall of the opposite side wall of the inner container. Thus, the weight of the septum and optionally an evaporator resting on it can be introduced into the side walls, whose load capacity is usually better than that of the ceiling of the inner container.

Vorzugsweise erstreckt sich die Scheidewand über die gesamte Breite der Ausstülpung und ist an beiden Seitenwänden des Innenbehälters befestigt. Insbesondere erstreckt sich die Vertiefung über die gesamte Breite der Scheidewand.Preferably, the septum extends over the entire width of the protuberance and is attached to both side walls of the inner container. In particular, the depression extends over the entire width of the septum.

Wenn die Vertiefung zwischen einem Einlassbereich der Verdampferkammer und dem Verdampfer angeordnet ist, kann sie gleichzeitig als ein Luftführungselement dienen, mit dessen Hilfe im Lufteinlassbereich in die Verdampferkammer eingetretene Luft gleichmäßig auf die Querschnittsfläche des Verdampfers verteilt wird.If the depression is arranged between an inlet region of the evaporator chamber and the evaporator, it can simultaneously serve as an air guide element with the aid of which air which has entered the evaporator chamber in the air inlet region is distributed uniformly over the cross-sectional area of the evaporator.

Vorzugsweise hat die Aussparung eine dem Lufteinlassbereich zugewandte flach geneigte Flanke, um die einströmende Luft mit geringen Strömungsverlusten zu führen, wohingegen eine dem Verdampfer zugewandte Flanke vorzugsweise steil geneigt ist, um eine hohe Steifigkeit der Scheidewand bei geringem Materialeinsatz zu erreichen.Preferably, the recess has a flat inclined flank facing the air inlet region in order to guide the incoming air with low flow losses, whereas an edge facing the evaporator is preferably steeply inclined in order to achieve a high rigidity of the septum with low material usage.

Ein Lüftungsgitter des Einlassbereichs ist vorzugsweise einteilig mit der Scheidewand ausgeformt.A ventilation grille of the inlet region is preferably formed integrally with the septum.

An einer Rückwand des Innenbehälters kann eine Luftkanalabdeckung vorgesehen sein, um zwischen der Rückwand und der Luftkanalabdeckung einen Kanal zu bilden, über den Kaltluft aus der Verdampferkammer im Lagerfach verteilt wird. Eine Oberkante dieser Luftkanalabdeckung kann zweckmäßigerweise auch zur Abstützung der Scheidewand dienen.On a rear wall of the inner container, an air duct cover may be provided to form between the rear wall and the air duct cover a channel, is distributed over the cold air from the evaporator chamber in the storage compartment. A top of this Air duct cover can expediently also serve to support the septum.

Vorzugsweise greift eine Lasche der Scheidewand zwischen die Luftkanalabdeckung und die Rückwand ein, so dass ein Abrutschen der Scheidewand auch während der Montage, noch vor einer dauerhaften Befestigung im Innenbehälter, sicher ausgeschlossen werden kann.Preferably, a tab of the septum engages between the air duct cover and the rear wall, so that slippage of the septum during assembly, even before a permanent attachment in the inner container, can be safely excluded.

Wenn die Ausstülpung nicht bis zur Vorderkante der Zwischenwand reicht, diese Vorderkante also höher als die Stärke der Zwischenwand im Bereich der Ausstülpung ist, so ist es besonders einfach, an dieser Vorderkante die Dichtungen von zwei Türen unterzubringen, die zu dem oberen bzw. unteren Lagerfach gehören.If the protuberance does not extend to the front edge of the intermediate wall, this leading edge is thus higher than the thickness of the intermediate wall in the area of the protuberance, it is particularly easy to accommodate at this leading edge the seals of two doors leading to the upper or lower storage compartment belong.

Fig. 1 zeigt eine perspektivische Teilansicht eines Haushalts-Kombinationskältegeräts. Ein nicht vollständig dargestellter oberer Teil des Korpus 1 des Geräts wird von einem Normalkühlfach 2 eingenommen. In einem unteren Teil des Korpus 1 befindet sich ein Gefrierfach 3. Beide Fächer haben in an sich bekannter Weise einen tiefgezogenen Innenbehälter 4 bzw. 5. Eine Bodenfläche des Innenbehälters 4 des Normalkühlfachs 2 und eine Deckenfläche des Innenbehälters 5 des Gefrierfachs 3 begrenzen eine horizontale Zwischenwand 6. Die Zwischenwand 6 ist an einem vorderen Rand 7 stärker als Seiten- und Rückwand des Korpus 1. So bietet der vordere Rand 7 ausreichend Platz, damit Dichtungen von (in den Figuren nicht dargestellten) Türen der beiden Fächer 2, 3 in geschlossener Stellung am vorderen Rand 7 dicht anliegen können. Fig. 1 shows a partial perspective view of a household combined refrigeration appliance. A not fully shown upper part of the body 1 of the device is occupied by a normal refrigeration compartment 2. In a known manner, both compartments have a deep-drawn inner container 4 or 5, respectively. A bottom surface of the inner container 4 of the normal refrigerating compartment 2 and a ceiling surface of the inner container 5 of the freezer compartment 3 define a horizontal intermediate wall 6. The intermediate wall 6 is stronger at a front edge 7 than the side and rear wall of the body 1. Thus, the front edge 7 provides sufficient space, so that seals of (not shown in the figures) doors of the two compartments 2, 3 in the closed position can be tight against the front edge 7.

Eine nach oben tiefgezogene Ausstülpung 8 nimmt einen großen Teil der Decke des Innenbehälters 5 ein. Die Ausstülpung 8 erstreckt sich über die gesamte Breite der Decke und von der Rückwand des Korpus 1 bis kurz vor den vorderen Rand 7. Die Ausstülpung 8 ist vom Gefrierfach 3 durch eine aus Kunststoff spritzgeformte Scheidewand 9 getrennt. Ein zentraler Abschnitt 10, der den überwiegenden Teil der Fläche der Scheidewand 9 bildet, ist horizontal ausgerichtet und liegt auf gleicher Höhe mit der Unterkante des vorderen Randes 7. Der zentrale Abschnitt 10 ist nach vorn begrenzt durch eine nach unten offene, sich über die gesamte Breite der Scheidewand 9 erstreckende Vertiefung 11. Die Vertiefung 11 hat eine an den zentralen Abschnitt 10 angrenzende steile Flanke 12, die zusammen mit an der Oberseite des zentralen Abschnitts 10 verteilten Rippen 13 zur Steifigkeit der Scheidewand 9 beiträgt. Nach vorn schließt an die Flanke 12 eine weniger steil abschüssige Flanke 14 an, die zusammen mit einer vorderen Schrägfläche 15 der Ausstülpung 8 einen Einlassbereich 16 begrenzt, über den Luft aus dem Gefrierfach 3 in die Ausstülpung 8 eingesogen wird, um wie in Fig. 2 gezeigt einen darin untergebrachten Verdampfer 17 zu durchströmen.An upwardly deep-drawn protuberance 8 occupies a large part of the ceiling of the inner container 5. The protuberance 8 extends over the entire width of the ceiling and from the rear wall of the body 1 to just before the front edge 7. The protuberance 8 is separated from the freezer compartment 3 by a molded plastic partition wall 9. A central portion 10, which forms the major part of the surface of the partition 9, is horizontally aligned and is level with the lower edge of the front edge 7. The central portion 10 is bounded forward by a downwardly open, over the entire The recess 11 has a steep flank 12 adjoining the central portion 10, which together with ribs 13 distributed at the top of the central portion 10 contribute to the rigidity of the partition wall 9. Forward to the edge 12 includes a less steeply sloping edge 14 which, together with a front inclined surface 15 of the protuberance 8 defines an inlet region 16, is sucked through the air from the freezer compartment 3 in the protuberance 8, as in Fig. 2 shown to flow through a housed therein evaporator 17.

Der Verdampfer 17 ist an seiner Ober- und Unterseite von Schaumstoffelementen 18, 19 umgeben, die dicht an den Innenbehälter 5 bzw. die Scheidewand 9 anschließen und so verhindern, dass Luft am Verdampfer 17 vorbei einen Ventilator 20 erreicht. Der Ventilator 20 hat in an sich bekannter Weise ein rotierendes Schaufelrad, dessen Durchmesser größer ist als die Höhe der Ausstülpung 8, so dass die Scheidewand 9 in der Umgebung des Ventilators 20 einen nach unten in das Gefrierfach 3 eingreifenden Vorsprung 21 aufweist.The evaporator 17 is surrounded at its top and bottom by foam elements 18, 19, which connect tightly to the inner container 5 and the septum 9 and thus prevent air from reaching the evaporator 17 a fan 20 over. The ventilator 20 has in a conventional manner a rotating paddle wheel whose diameter is greater than the height of the protuberance 8, so that the septum 9 in the vicinity of the fan 20 has a downwardly into the freezer compartment 3 engaging projection 21.

Im Anschluss an den Ventilator 20 erreicht die am Verdampfer 17 abgekühlte Luft einen sich entlang der Rückwand des Korpus 1 abwärts erstreckenden, vom Gefrierfach 3 durch eine plattenförmige Abdeckung 22 getrennten Luftkanal 23.Following the fan 20, the air cooled at the evaporator 17 reaches a downwardly extending along the rear wall of the body 1, from the freezer compartment 3 through a plate-shaped cover 22 separate air duct 23rd

Wie in Fig. 3 zu erkennen, endet die Abdeckung 22 kurz vor dem Boden des Gefrierfachs 3, und sie ist mit diversen Öffnungen 24 versehen, so dass die Kaltluft sich über die Öffnungen 24 und über einen Spalt zwischen der Unterkante der Abdeckung 22 und dem Boden im gesamten Gefrierfach 3 verteilt.As in Fig. 3 can be seen, the cover 22 ends just before the bottom of the freezer compartment 3, and it is provided with various openings 24 so that the cold air through the openings 24 and a gap between the lower edge of the cover 22 and the bottom in the entire freezer. 3 distributed.

Die Schnittebene der Fig. 3 verläuft entlang der bereits erwähnten Vertiefung 11. Die Vertiefung 11 hat vertikale seitliche Wandabschnitte 26 mit jeweils einer Öffnung 27 darin, die einer Öffnung oder Tasche 28 in einer Seitenwand der Ausstülpung 8 gegenüberliegt. Durch Einführen von stiftartigen Elementen wie etwa Bolzen, Schrauben oder dergleichen in die Öffnungen 27 und Taschen 28 wird ein vorderer Bereich der Scheidewand 9 im Korpus 1 fixiert.The cutting plane of the Fig. 3 The recess 11 has vertical lateral wall portions 26, each having an opening 27 therein, which faces an opening or pocket 28 in a side wall of the protuberance 8. By inserting pin-like elements such as bolts, screws or the like in the openings 27 and pockets 28, a front portion of the partition 9 is fixed in the body 1.

Ein rückwärtiger Bereich der Scheidewand 9 ist über Laschen 29 gehalten, die wie in Fig. 4 gezeigt, von einem hinteren Rand der Scheidewand 9 nach unten abstehen und über die obere Kante der Abdeckung 22 hinweg in den Luftkanal 23 eingreifen.A rear portion of the septum 9 is held by tabs 29 which, as in FIG Fig. 4 shown projecting from a rear edge of the partition wall 9 down and engage over the upper edge of the cover 22 away in the air channel 23.

Wie in Fig. 4 ferner gut zu erkennen, ist ein Lüftungsgitter 20 einteilig mit der Scheidewand 9 ausgebildet und umfasst in Tiefenrichtung des Korpus 1 orientierte Rippen und parallel zur vorderen Schrägfläche der Ausstülpung 8 und der Flanke 14 orientierte Leitflächen 31.As in Fig. 4 Furthermore, a ventilation grille 20 is formed integrally with the partition wall 9 and comprises ribs oriented in the depth direction of the body 1 and guide surfaces 31 oriented parallel to the front oblique surface of the protuberance 8 and the flank 14.

Eine flache Aussparung 32 in der Rückwand des Korpus liegt dem Ventilator 20 gegenüber, um die von ihm angetriebene Luftströmung mit geringem Strömungswiderstand nach unten in den Luftkanal 23 umzulenken.A flat recess 32 in the rear wall of the body is opposite the fan 20 to deflect the driven by him air flow with low flow resistance down into the air duct 23.
