Description

Die Erfindung bezieht sich auf einen Einbau-Kühlschrank nach dem Oberbegriff des Anspruches 1.The invention relates to a built-in refrigerator according to the preamble of claim 1.

Einbau-Kühlschränke werden in eine Einbauküche derart integriert, daß sie sich in die Küchenmöbel einfügen. Die Kühlschranktür ist mit einer Möbeltür versehen, deren Dekor an das Dekor der übrigen Küchenmöbel angepaßt ist. Durch das DE-GM 84 14 458 ist ein Einbau-Kühlschrank der im Oberbegriff des Anspruches 1 beschriebenen Bauart bekannt geworden. Dabei hat der zwischen der Unterkante der Kühlschrank-Möbeltür und der Oberkante der Möbel-Sockelblende gebildete Luftführungskanal einen solchen freien Querschnitt, daß die mit dem Ventilator umgewälzte Luft zur Kühlung des Kondensators ungehindert ein- und ausströmen kann.Built-in refrigerators are integrated in a fitted kitchen in such a way that they fit into the kitchen furniture. The refrigerator door is provided with a furniture door, the decor of which is adapted to the decor of the other kitchen furniture. From DE-GM 84 14 458 a built-in refrigerator of the type described in the preamble of claim 1 has become known. The air duct between the lower edge of the refrigerator furniture door and the upper edge of the furniture plinth panel has such a free cross-section that the air circulated with the fan for cooling the condenser can flow in and out unhindered.

Durch die US-PS 37 36 768 ist ein Kühlschrank mit einer frontseitigen gitterförmigen Luftein- und Luftauslaßöffnung und mit einem etwa U-förmigen Strömungsverlauf bekannt geworden. Dabei sind im Geräteraum im rückwärtigen Bereich des Kühlschrankes ein Kondensator, ein Ventilator und ein Kompressor angeordnet, während im Bereich der frontseitigen Ausströmöffnung eine Abflußwanne liegt.From US-PS 37 36 768 a refrigerator with a front grid-shaped air inlet and air outlet and with an approximately U-shaped flow profile has become known. A condenser, a fan and a compressor are arranged in the equipment room in the rear area of the refrigerator, while a drain pan is located in the area of the front outflow opening.

Der Erfindung liegt die Aufgabe zugrunde, bei einem Einbau-Kühlschrank der eingangs genannten Art die Luftführung zu verbessern.The invention has for its object to improve the air flow in a built-in refrigerator of the type mentioned.

Diese Aufgabe wird erfindungsgemäß mit den kennzeichnenden Merkmalen des Anspruches 1 gelöst. Durch das Profilteil, das mit voneinander getrennten Lufteinlaßöffnungen versehen ist, erfolgt eine gerichtete Luftzu- und Luftabführung. Ferner ist die Lufteinlaßöffnung im Bereich des Ventilators und die Luftauslaßöffnung im Bereicvh einer Verdunsterwanne vorgesehen, so daß durch diese gerichtete Luftführung eine optimale Kühlung ermöglicht werden kann. Der durch die Möbeltür einserseits und die Möbel-Sockelblende andererseits gebildete Luftführungskanal mündet bei der Bauart gemäß der Erfindung mit Hilfe des Hohlprofiles in den Gerätesockel, wobei durch die enge Anlage des Hohlprofiles an dem Schenkel der Sockelblende und an der Unterseite des Kühlschrankgehäuses der Eintritt von Fremdluft vermieden wird. Die oberhalb der Möbel-Sockelblende vorhandene Luftführungsöffnung ist somit durch Einfügen des Hohlprofiles mit der Blende weitgehend verdeckt, so daß sich außerdem ein wirksamer Berührungsschutz ergibt. Die Luftein- und Luftauslaßöffnungen sind durch das Profilteil auch bei geöffneter Tür kaschiert. Die Möbel-Sockelblende kann aus gleichem Material wie benachbarte Einbau-Möbel bestehen, sie ist nicht durch Lüftungsschlitze unterbrochen, so daß in der Einbauküche eine geschlossene Möbel-Sockelblende für sämtliche Einbau-Möbel verwendet werden kann.This object is achieved with the characterizing features of claim 1. Through the profile part, which is provided with separate air inlet openings, there is a directed air supply and air discharge. Furthermore, the air inlet opening in the area of the fan and the air outlet opening in the area of an evaporation trough are provided, so that optimum cooling can be made possible by this directed air flow. The air duct formed by the furniture door on the one hand and the furniture plinth on the other side opens in the construction according to the invention with the help of the hollow profile in the appliance base, the entry of extraneous air through the tight fit of the hollow profile on the leg of the plinth and on the underside of the refrigerator housing is avoided. The air duct opening above the furniture plinth panel is thus largely covered by inserting the hollow profile with the panel, so that there is also effective protection against contact. The air inlet and outlet openings are concealed by the profile part even when the door is open. The furniture plinth can be made of the same material as neighboring built-in furniture, it is not interrupted by ventilation slots, so that a closed furniture plinth can be used for all built-in furniture in the kitchen.

Weitere Merkmale der Erfindung ergeben sich aus den weiteren Ansprüchen, der Beschreibung und den Zeichnungen.Further features of the invention result from the further claims, the description and the drawings.

in a schematic and perspective view of the base according to FIG. 1 with a slide which is pulled out of the base.

Der Gerätesockel hat ein wannenförmiges Gehäuse 1 mit einem Boden 2 und Seitenwänden 3 bis 6. In der Seitenwand 3 sind nebeneinander zwei rechteckförmige Ausnehmungen 7 und 8 (Fig. 3) vorgesehen, die durch einen vertikalen schmalen Steg 9 voneinander getrennt sind.The device base has a trough-shaped housing 1 with a base 2 and side walls 3 to 6. In the side wall 3, two rectangular recesses 7 and 8 (FIG. 3) are provided side by side, which are separated from one another by a vertical narrow web 9.

Die Ausnehmungen 7, 8 sind nach oben offen. Durch diese Ausnehmungen 7, 8 ist der Innenraum des Gehäuses 1 in der Einbaulage des Sockels zugänglich, um die darin befindlichen Aggregate beispielsweise reinigen zu können, ohne den Sockel ausbauen zu müssen.The recesses 7, 8 are open at the top. Through these recesses 7, 8, the interior of the housing 1 is accessible in the installed position of the base in order, for example, to be able to clean the units therein without having to remove the base.

Vom Steg 9 aus erstreckt sich ein senkrecht auf dem Boden 2 stehender Steg 10 in Richtung auf die Rückwand 5. Er ist durch einen parallel zu den Seitenwänden 3 und 5 verlaufenden Steg 11 mit der Seitenwand 6 verbunden. Die Stege 10, 11 sowie ein Teil der Seitenwände 3 und 6 begrenzen eine im Umriß rechteckförmige Verdunsterwanne 12, die unmittelbar hinter der Ausnehmung 8 liegt. In ihr kann sich das im Betrieb des Einbau-Kühlschrankes anfallende überschüssige Tauwasser sammeln. Um ein Überlaufen des Tauwassers in das Gehäuse 1 zu verhindern, ist in der Verdunsterwanne 12 ein Überlaufstutzen 13 vorgesehen (Fig. 1).From the web 9, a web 10 standing perpendicularly on the floor 2 extends in the direction of the rear wall 5. It is connected to the side wall 6 by a web 11 running parallel to the side walls 3 and 5. The webs 10, 11 and part of the side walls 3 and 6 delimit an evaporation trough 12 which is rectangular in outline and which lies immediately behind the recess 8. The excess condensation water that accumulates during operation of the built-in refrigerator can collect in it. In order to prevent the condensation water from overflowing into the housing 1, an overflow connection 13 is provided in the evaporation trough 12 (FIG. 1).

Unmittelbar hinter der Ausnehmung 7 ist auf dem Boden 2 des Gehäuses 1 ein Ventilator 14 montiert. Der Ventilator 14 als Querstromlüfter ermöglicht eine flache Bauweise, so daß das Sockelgehäuse 1 niedrig gehalten werden kann. Mit dem Ventilator 14 wird Kühlluft aus dem Aufstellraum des Einbau-Kühlschrankes in den Sockel angesaugt.A fan 14 is mounted directly behind the recess 7 on the bottom 2 of the housing 1. The fan 14 as a cross-flow fan enables a flat design, so that the base housing 1 can be kept low. With the fan 14, cooling air is drawn into the base from the installation space of the built-in refrigerator.

Im Bereich der Ecken des Gehäuses 1 sind (nicht dargestellte) Gewindesockel vorgesehen, in die höhenverstellbar Füße 15 und 16 (Fig. 2) geschraubt werden.In the area of the corners of the housing 1, threaded bases (not shown) are provided, into which height-adjustable feet 15 and 16 (FIG. 2) are screwed.

Das Kühlschrankgehäuse 18 (Fig. 2) ist auf das Sockelgehäuse 1 derart aufgesetzt, daß es auf den Seitenwänden 3 bis 6 aufsitzt und mit den Seitenwänden 4 bis 6 bündig liegt. Der Boden 19 des Kühlschrankgehäuses 18 bildet eine wannenförmige Vertiefung, die sich über den größten Teil der Tiefe und der Breite des Gehäuses 1 erstrecken kann. Durch den nach unten versetzten Gehäuseboden 19 wird ein Lagerfach beispielsweise für Gemüseschalen gebildet. Frontseitig ist der Gehäuseboden 19 über den Möbelsockel 42 schräg aufwärts gerichtet, so daß ein Luftschacht gebildet ist.The refrigerator housing 18 (Fig. 2) is placed on the base housing 1 such that it sits on the side walls 3 to 6 and is flush with the side walls 4 to 6. The bottom 19 of the refrigerator housing 18 forms a trough-shaped depression that can extend over most of the depth and width of the housing 1. A storage compartment for vegetable dishes, for example, is formed by the housing base 19 which is offset downwards. At the front, the housing base 19 is directed obliquely upwards over the furniture base 42, so that an air shaft is formed.

An der Vorderwand 3 des Sockelgehäuses 1 ist eine L-förmige Sockelblende 26 lösbar befestigt. Zu Kontrollzwecken kann die Sockelblende 26 abgenommen werden, so daß die Aggregate durch die Ausnehmungen 7, 8 hindurch erreichbar sind. Am kurzen Schenkel 28 der Sockelblende 26 ist ein über die ganze Breite des Sockelgehäuses sich erstreckendes Hohlprofil 29 befestigt, dessen vordere Stirnfläche 30 (Fig. 2) schräg nach unten verläuft. In der Stirnfläche 30 des Hohlprofiles 29 ist im Bereich des Ventilators 14 eine Lufteinlaßöffnung 31 (Fig. 1) und im Bereich der Ausnehmung 8 eine Luftauslaßöffnung 32 vorgesehen. Seitlich wird die Lufteinlaßöffnung 31 von Wänden 33 und 34 und die Luftauslaßöffnung 32 von Wänden 35 und 36 begrenzt. Etwa in halber Breite der Lufteinlaßöffnung 31 und der Luftauslaßöffnung 32 ist jeweils eine Querwand 38, 39 vorgesehen. Die Wände 34, 35 und die Querwände 38, 39 bilden Zwischenwände des Hohlprofiles 29. Die Zwischenwände bilden Luftleitflächen, an denen die angesaugte bzw. ausgeblasene Kühlluft umgelenkt wird.On the front wall 3 of the base housing 1, an L-shaped base panel 26 is releasably attached. For control purposes, the base panel 26 can be removed so that the units can be reached through the recesses 7, 8. On the short leg 28 of the base panel 26, a hollow profile 29 is attached which extends over the entire width of the base housing and whose front end face 30 (FIG. 2) runs obliquely downwards. In the end face 30 of the hollow profile 29, an air inlet opening 31 (FIG. 1) is provided in the region of the fan 14 and an air outlet opening 32 in the region of the recess 8. The air inlet opening 31 is laterally delimited by walls 33 and 34 and the air outlet opening 32 by walls 35 and 36. A transverse wall 38, 39 is provided in each case approximately half the width of the air inlet opening 31 and the air outlet opening 32. The walls 34, 35 and the transverse walls 38, 39 form intermediate walls of the hollow profile 29. The intermediate walls form air guiding surfaces on which the sucked-in or blown-out cooling air is deflected.

Wie Fig. 2 zeigt, erstreckt sich von der Vorderkante des Hohlprofiles 29 aus eine Blende 41 senkrecht nach unten. Sie endet mit geringem Abstand oberhalb einer Möbelsockelblende 42. Die Blende 41 kann mit dem Hohlprofil 29 z.B. an der Abdeckblende 44 geführt, auf die Stirnseite der Möbelsockelblende 42 mittels Rasten ausgerichtet werden. Die Abdeckblende 44 ist an der Unterseite des Kühlschrankgehäuses befestigt, und deckt das Hohlprofil 29 nach oben ab. Auf der Kühlschranktür 45 ist eine Möbeltür 46 befestigt, die in ihrem Dekor an die übrigen Einbau-Küchenmöbel angepaßt ist. Die Unterkante 47 der Möbeltür 46 liegt in Höhe der Oberkante 48 der Sockelblende 42. Wie Fig. 2 zeigt, liegt die Möbeltür 46 mit Abstand vor der Sockelblende 42. Das Hohlprofil 29 mit der Lufteinlaßöffnung 31 und der Luftauslaßöffnung 32 liegt mit Abstand oberhalb der Möbelsockelblende 42 und mit Abstand hinter der Möbeltür 46, so daß das Hohlprofil bei geschlossenem Kühlschrank nicht sichtbar ist.As shown in FIG. 2, an aperture 41 extends vertically downward from the front edge of the hollow profile 29. It ends at a short distance above a furniture base panel 42. The panel 41 can be guided with the hollow profile 29, for example on the cover panel 44, and aligned with the front side of the furniture base panel 42 by means of catches. The cover panel 44 is attached to the underside of the refrigerator housing, and covers the hollow profile 29 upwards. On the refrigerator door 45, a furniture door 46 is attached, which is adapted in its decor to the other built-in kitchen furniture. The lower edge 47 of the furniture door 46 lies at the level of the upper edge 48 of the base panel 42. As shown in FIG. 2, the furniture door 46 is at a distance from the base panel 42. The hollow profile 29 with the air inlet opening 31 and the air outlet opening 32 is at a distance above the furniture base panel 42 and at a distance behind the furniture door 46 so that the hollow profile is not visible when the refrigerator is closed.

Auf dem Boden 2 des Gehäuses 1 stehend, sind Luftleitrippen 49 vorgesehen, die im Ausführungsbeispiel paarweise etwa in Höhe der axialen Enden des Ventilators 14 liegen. Die Luftleitrippen 49 divergieren in Richtung auf die Gehäuserückwand 5. Die jeweils äußersten Luftleitrippen 49 sind durch parallel zur Vorderwand 3 des Gehäuses 1 verlaufende Wände 50 und 51 mit der Seitenwand 4 und dem Steg 10 verbunden.Standing on the bottom 2 of the housing 1, air guide ribs 49 are provided, which in the exemplary embodiment lie in pairs approximately at the level of the axial ends of the fan 14. The air guide ribs 49 diverge in the direction of the rear wall 5 of the housing. The outermost air guide ribs 49 are connected to the side wall 4 and the web 10 by walls 50 and 51 running parallel to the front wall 3 of the housing 1.

Hinter den Luftleitrippen 49 ist ein Verflüssiger 54 angeordnet, der zwei achsparallel zueinanderliegende Wendeln aufweist.A condenser 54 is arranged behind the air-guiding ribs 49 and has two coils that are axially parallel to one another.

Der Verflüssiger 54 ist mit einem Kompressor 55 verbunden.The condenser 54 is connected to a compressor 55.

Damit die Wendeln des Verflüssigers 54 leicht zugänglich sind, sind im Boden 2 und in der Seitenwand 4 des Gehäuses 1 Ausnehmungen 56 und 57 vorgesehen (Fig. 3), die durch einen L-förmigen Schieber 58 geschlossen werden können. Im Boden 2 des Gehäuses 1 sind für den Schieber 58 entsprechende Führungen vorgesehen. Der Schieber 58 kann seitlich herausgezogen werden, so daß der Verflüssiger 54 von der Seite und von unten beispielsweise zur Reinigung zugänglich ist.So that the coils of the condenser 54 are easily accessible, recesses 56 and 57 are provided in the bottom 2 and in the side wall 4 of the housing 1 (FIG. 3), which can be closed by an L-shaped slide 58. Appropriate guides are provided in the bottom 2 of the housing 1 for the slide 58. The slide 58 can be pulled out laterally so that the condenser 54 is accessible from the side and from below, for example for cleaning.

Im Betrieb des Einbau-Kühlschrankes wird durch den Ventilator 14 Luft aus dem Aufstellraum angesaugt. Zwischen der Möbelsockelblende 42 und der Möbeltür 46 ist ein kanalförmiger Luftzuführbereich gebildet. Die Luft wird in Richtung des Pfeiles 62 (Fig. 2) angesaugt. Nach dem Durchtritt durch das Hohlprofil 29 gelangt die angesaugte Kühlluft zum Ventilator 14. Über den Verflüssiger 54 wird die angesaugte Luft nach hinten in Richtung auf die Rückwand 5, geleitet. An der Gehäuserückwand 5 wird die Kühlluft rechtwinklig in Richtung auf den Kompressor 55 umgelenkt, der dadurch ebenfalls mit Kühlluft bestrichen wird. An der Gehäuseseitenwand 6 wird die Kühlluft schließlich nochmals um 90o umgelenkt und über die Verdunsterwanne 12 hinweg zur Luftauslaßöffnung 32 geführt. Da die Kühlluft über die Verdunsterwanne 12 geführt wird, wird die Verdunstung des in der Wanne sich ansammelnden Tauwassers begünstigt. Die aus der Luftauslaßöffnung 32 ausströmende Luft strömt hinter der Tür 46 aus dem Sockel und wird an der Tür nach unten abgelenkt, so daß sie zwischen der Tür und der Möbelsockelblende 42 in den Aufstellraum austreten kann.When the built-in refrigerator is in operation, fan 14 draws air from the installation room. A channel-shaped air supply area is formed between the furniture base panel 42 and the furniture door 46. The air is drawn in in the direction of arrow 62 (FIG. 2). After passing through the hollow profile 29, the sucked-in cooling air reaches the fan 14. Via the condenser 54, the sucked-in air is directed towards the rear toward the rear wall 5. On the rear wall 5 of the housing, the cooling air is deflected at right angles in the direction of the compressor 55, which is also coated with cooling air. The cooling air is finally again o deflected by 90 and passed over the Verdunsterwanne 12 to the air outlet port 32 on the housing side wall. 6 Since the cooling air is guided over the evaporation trough 12, the evaporation of the condensation water that accumulates in the trough is promoted. The air flowing out of the air outlet opening 32 flows out of the base behind the door 46 and is deflected downward at the door so that it can exit into the installation space between the door and the furniture base cover 42.
