Description

Die vorliegende Erfindung betrifft ein Kältegerät, das für den Einbau in einer Möbelnische vorgesehen ist. Für derartige Kältegeräte sind gegenwärtig zwei verschiedene Bauformen verbreitet.The present invention relates to a refrigerator, which is intended for installation in a furniture niche. For such refrigerators currently two different types are common.

Bei einer ersten Bauform ist aus einem im Wesentlichen quaderförmigen wärmeisolierenden Gehäuse ein Maschinenraum ausgespart, in dem wenigstens ein Verdichter für das in dem Kältegerät zirkulierende Kältemittel untergebracht ist. Ein Verflüssiger für das Kältemittel ist an der Rückwand des isolierenden Gehäuses frei hängend montiert und durch die Konvektion von an dem Verflüssiger sich erwärmender, aufsteigender Luft gekühlt.In a first embodiment, a machine room is recessed from a substantially cuboid heat-insulating housing, in which at least one compressor for the circulating in the refrigerator refrigerant is housed. A condenser for the refrigerant is mounted to hang freely on the rear wall of the insulating housing and cooled by the convection of ascending air at the condenser.

Bei einer zweiten bekannten Bauform sind mit Ausnahme des Verdampfers im Wesentlichen alle Komponenten des Kältekreislaufs in einem fest unter dem Gehäuse montierten Sockelaggregat untergebracht. Dadurch kann ein sehr günstiges Verhältnis von Volumen zu Oberfläche des Gehäuses erreicht werden, was zu einem geringen Bedarf an Kühlleistung führt; allerdings kann zum Abführen der Abwärme eines solchen Sockelaggregats Konvektion nicht mehr genutzt werden, so dass hierfür eine Zwangsbelüftung erforderlich wird. Außerdem geht in der Einbaunische durch das Sockelaggregat belegter Raum den Benutzern als Stauraum für andere Zwecke verloren.In a second known design substantially all components of the refrigeration cycle are housed in a fixedly mounted under the housing base unit with the exception of the evaporator. As a result, a very favorable ratio of volume to surface area of the housing can be achieved, which leads to a low requirement for cooling capacity; However, to dissipate the waste heat of such a base unit convection can no longer be used, so that a forced ventilation is required. In addition, space occupied by the base unit is lost to users as storage space for other purposes.

Die Erfindung betrifft außerdem Baugruppen für ein Kältegerät sowie ein Verfahren zum installieren eines Kältegeräts.The invention also relates to assemblies for a refrigeration device and a method for installing a refrigeration device.

WO 03/012350 A1 beschreibt ein freistehendes Kältegerät zur Präsentation von Getränken im Verkauf, bei dem Bauteile des Kälteaggregates gegen leistungsstärkere bzw. leistungsschwächere Bauteile ausgetauscht werden können. WO 03/012350 A1 describes a free-standing refrigeration appliance for the presentation of drinks in the sale, in which components of the refrigeration unit can be replaced by more powerful or less powerful components.

Die gattungsgemäße DE 298 20 774 U1 beschreibt ein Mini-Kältegerät zur Kühlung von Kosmetika und Medikamenten in Badezimmerschränken, bei dem eine erste Baugruppe in Schulterhöhe und eine zweite Baugruppe in einem unteren Bereich des Badmöbels untergebracht sind.The generic DE 298 20 774 U1 describes a mini-refrigerator for cooling cosmetics and medicines in bathroom cabinets, in which a first assembly at shoulder level and a second assembly are housed in a lower portion of the bathroom furniture.

US 2002/0014086 A1 offenbart ein in ein Küchenmöbel eingebrachtes Kältegerät, dessen Basis die Kühlaggregate aufweist, und das zusätzlich ein isoliertes Gehäuse zur Aufnahme von Kühlgut stützt. US 2002/0014086 A1 discloses a built-in kitchen furniture refrigeration device, whose base has the cooling units, and additionally supports an insulated housing for receiving refrigerated goods.

EP 0 272 761 A2 beschreibt ein freistehendes Gefriergerät, dessen Gehäuse im hinteren Bereich gestuft ausgebildet ist, um so einen Maschinenraum zu bilden. EP 0 272 761 A2 describes a freestanding freezer, the housing is stepped in the rear area designed so as to form a machine room.

Aufgabe der vorliegenden Erfindung ist, ein Kältegerät und Baugruppen für ein Kältegerät zu schaffen, die eine hohe Energieeffizienz erreichen und gleichzeitig in einer Einbaunische verfügbaren Platz sehr ökonomisch zu nutzen erlauben.The object of the present invention is to provide a refrigeration device and assemblies for a refrigeration device, which achieve high energy efficiency and at the same time make it possible to use space available in an installation niche very economically.

Eine weitere Aufgabe ist, ein Verfahren zum Installieren eines solchen Kältegeräts in einem Küchenmöbel zu schaffen.Another object is to provide a method for installing such a refrigerator in a kitchen furniture.

Die Aufgaben werden gelöst durch ein Kältegerät mit den Merkmalen des Anspruchs 1, Baugruppen mit den Merkmalen der Ansprüche 9 bzw. 10 und ein Verfahren gemäß Anspruch 11.The objects are achieved by a refrigeration device with the features of claim 1, assemblies with the features of claims 9 and 10 and a method according to claim 11.

Indem bei dem erfindungsgemäßen Kältegerät die herkömmliche feste Verbindung zwischen dem wärmeisolierenden Gehäuse einerseits und dem Sockelaggregat andererseits aufgehoben wird, wird die Möglichkeit geschaffen, beide örtlich getrennt voneinander in weitgehend beliebigen Positionen in Bezug aufeinander in einem Möbel wie etwa einem Küchenschrank unterzubringen. Für die Unterbringung der das Gehäuse umfassenden ersten Baueinheit kann eine gut zugängliche Zone des Möbels gewählt werden, während die den Verdichter umfassende zweite Baueinheit in einer schlecht zugänglichen Zone platziert werden kann, deren anderweitige Nutzung wenig attraktiv ist oder die anderenfalls überhaupt nicht nutzbar wäre. Eine solche Zone ist insbesondere der bei den meisten Küchenmöbeln vorhandene Sockelbereich, in unmittelbarer Nachbarschaft zum Fußboden. Durch das erfindungsgemäße Kältegerät ist damit ein bislang ungenutzter Raum als sogenannter Maschinenraum erschlossen, wodurch sich ein Stauraumgewinn entweder für das Kältegerät oder den das Kältegerät aufnehmenden Einbauschrank ergibt.By eliminating the conventional fixed connection between the heat-insulating housing on the one hand and the base unit on the other hand, in the refrigerator according to the invention, the possibility is created to accommodate both locally separated from each other in largely arbitrary positions with respect to each other in a furniture such as a kitchen cabinet. For accommodating the housing comprising the first unit, an easily accessible zone of the furniture can be selected, while the compressor comprising the second unit can be placed in a poorly accessible zone, the other use is not attractive or otherwise would not be usable. Such a zone is in particular the base area present in most kitchen furniture, in the immediate vicinity of the floor. By the refrigeration device according to the invention thus a previously unused space is opened up as a so-called engine room, resulting in a storage space gain for either the refrigerator or the refrigerator receiving the built-in closet.

Im Prinzip ist es möglich, die zwei Baueinheiten des erfindungsgemäßen Kältegeräts ab Werk miteinander im Wesentlichen nur durch eine Kältemittelleitung, nicht aber durch starre mechanische Verbindungselemente verbunden, auszuliefern. Dies hat den Vorteil, dass der Kältemittelkreislauf des Kältegeräts bereits im Werk dicht zusammengefügt werden kann, und dass Probleme vermieden werden, die sich ergeben können, wenn etwa der Kältemittelkreislauf erst nach erfolgter Montage des Kältegeräts an seinem Einbauort mit Kältemittel gefüllt wird oder bei der Montage bereits werksseitig mit Kältemittel gefüllte Teile des Kältemittelkreises zusammengefügt werden müssen. Da eine solche Verbindung die Handhabung der zwei Baugruppen des Kältegeräts bei der Montage erheblich erschwert, ist jedoch vorzugsweise in einer die zwei Baugruppen verbindenden Kältemittelleitung eine Kupplung vorgesehen, die es ermöglicht, die zwei Baugruppen getrennt voneinander im Möbel zu montieren und erst nach der Montage zusammenzufügen.In principle, it is possible, the two units of the refrigerator according to the invention ex works with each other essentially only by a refrigerant pipe, but not by rigid mechanical fasteners connected deliver. This has the advantage that the refrigerant circuit of the refrigerator can be tightly assembled already in the factory, and that problems are avoided that may arise if, for example, the refrigerant circuit is filled with refrigerant after installation of the refrigerator at its installation location with refrigerant or during assembly already factory-filled with refrigerant parts of the refrigerant circuit must be joined together. Since such a connection makes the handling of the two components of the refrigeration device during assembly considerably more difficult, however, a coupling is preferably provided in a connecting the two modules refrigerant line, which makes it possible to mount the two modules separately from each other in the furniture and put together only after assembly ,

Vorzugsweise besteht eine solche Kupplung aus zwei Teilen, die jeweils an dem Leitungsstück der ersten Baugruppe bzw. der zweiten Baugruppe angebracht sind, und die im ungekoppelten Zustand selbstverschließend sind. Derartige Kupplungen, die dafür ausgelegt sind, im ungekoppelten Zustand das Entweichen von Kältemittel zu verhindern, sind aus der Klimatechnik bekannt. Ihre Verwendung macht es möglich, die zwei Teile des Kältemittelkreislaufs des erfindungsgemäßen Kältegeräts, die auf die erste bzw. die zweite Baugruppe entfallen, unabhängig von einander bereits im Werk mit Kältemittel zu befüllen und dennoch ein unkontrolliertes Entweichen von Kältemittel in die Atmosphäre zu verhindern.Preferably, such a coupling consists of two parts, which are respectively attached to the line piece of the first assembly and the second assembly, and which are self-closing in the uncoupled state. Such couplings, which are designed to prevent the escape of refrigerant in the uncoupled state, are known from the air conditioning. Their use makes it possible for the two parts of the refrigerant circuit of the refrigerator according to the invention, which accounts for the first and the second module, independently of each other already in the factory to fill with refrigerant and yet to prevent uncontrolled escape of refrigerant into the atmosphere.

Zweckmäßigerweise ist die zweite Baugruppe mit einer Zwangsbelüftung ausgestattet, damit sie auch in Zonen eines Möbels eingebaut werden kann, die anderenfalls nur unzureichend kühlbar wären.Conveniently, the second assembly is equipped with a forced ventilation so that it can be installed in zones of furniture that would otherwise be insufficiently coolable.

Ein Verflüssiger kann im Prinzip wahlweise als Teil der ersten oder der zweiten Baugruppe vorgesehen werden. Insbesondere wenn die zweite Baugruppe zwangsbelüftet ist, ist es sinnvoll, den Verflüssiger in die zweite Baugruppe zu integrieren.A condenser may, in principle, optionally be provided as part of the first or the second assembly. In particular, if the second module is forced ventilation, it makes sense to integrate the condenser in the second module.

Eine Kondenswasserleitung zum Ableiten von sich im Innenraum des Gehäuses niederschlagender Feuchtigkeit ist zweckmäßigerweise zusammen mit der Kältemittelleitung in einem Strang geführt. In einem solchen Fall ist die Kondenswasserleitung zweckmäßigerweise wie die Kältemittelleitung mit einer Kupplung versehen.A condensed water line for draining moisture precipitating in the interior of the housing is expediently guided together with the refrigerant line in one strand. In such a case, the condensed water line is expediently provided with a coupling, like the refrigerant line.

Eine Verdampferschale, an der die Kondenswasserleitung endet, ist zweckmäßigerweise in die zweite Baugruppe integriert, um die dort vom Verdichter frei gesetzte Abwärme zum Verdunsten des Kondenswassers zu nutzen.An evaporator shell, at which the condensed water line ends, is expediently integrated into the second module in order to use the waste heat released there by the compressor to evaporate the condensed water.

Weitere Merkmale und Vorteile der Erfindung ergeben sich aus der nachfolgenden Beschreibung eines Ausführungsbeispiels unter Bezugnahme auf die beigefügte

Fig. 1
die eine schematischen Schnitt durch ein erfindungsgemäßes Kältegerät, eingebaut in einem Küchenschrank, zeigt.
Further features and advantages of the invention will become apparent from the following description of an embodiment with reference to the accompanying
Fig. 1
which shows a schematic section through an inventive refrigeration device installed in a kitchen cabinet.

Der in Fig. 1 im Schnitt gezeigte Einbauschrank 1 hat in seinem oberen Bereich eine Nische 2, die eine erste Baugruppe 3 des erfindungsgemäßen Kältegeräts aufnimmt. Diese erste Baugruppe 3 umfasst im Wesentlichen ein wärmeisolierendes Gehäuse mit einem Korpus 4 und einer Tür 5, die einen Innenraum 6 zur Lagerung von Kühlgut umschließen. In der Figur ist der Innenraum 6 exemplarisch ohne Unterteilung und mit einem einzigen Verdampfer 7 an seiner Rückwand dargestellt, selbstverständlich könnte er auch durch Trennwände in mehrere unterschiedliche Temperaturzonen unterteilt sein, die gegebenenfalls jeweils mit einem eigenen Verdampfer ausgestattet sein können, der unabhängig von den Verdampfern der anderen Zonen mit Kältemittel versorgbar ist, oder es könnte sich um ein Gerät in No-Frost-Bauweise handeln, bei dem der Verdampfer in einer vom Innenraum über eine Zwangslüftung kommunizierenden Kammer untergebracht ist.The in Fig. 1 Installation cabinet 1 shown in section has a niche 2 in its upper area, which accommodates a first assembly 3 of the refrigeration appliance according to the invention. This first assembly 3 essentially comprises a heat-insulating housing with a body 4 and a door 5, which has an inner space 6 for the storage of goods to be cooled enclose. In the figure, the interior 6 is exemplarily shown without subdivision and with a single evaporator 7 on its back wall, of course, it could also be divided by partitions in several different temperature zones, which may optionally be equipped with its own evaporator, regardless of the evaporators the other zones can be supplied with refrigerant, or it could be a device in no-frost construction, in which the evaporator is housed in a communicating from the interior via a forced ventilation chamber.

Eine Zulaufleitung 8 und eine Ablaufleitung 9 für die Kältemittelversorgung des Verdampfers 7 sind an der Rückseite des Korpus 4 herausgeführt und enden gemeinsam an einem Kupplungsteil 10.A supply line 8 and a drain line 9 for the refrigerant supply of the evaporator 7 are led out at the back of the body 4 and terminate together on a coupling part 10th

Unterhalb des Verdampfers 7 ist an der Rückwand des Innenraums 6 eine Auffangrinne 11 für vom Verdampfer 7 ablaufendes Kondenswasser gebildet. Eine Abflussleitung 12 ist von einem tiefsten Punkt der Auffangrinne 11 ausgehend an der Rückseite des Korpus 4 herausgeführt und endet wie die Leitungen 8, 9 an dem Kupplungsteil 10. Das Kupplungsteil 10 weist somit drei Verbinderelemente auf, eines für jede Leitung 8, 9, 12, wobei wenigstens die den Leitungen 8, 9 zugeordneten Verbinderelemente im unverbundenen Zustand des Kupplungsteils 10 selbstschließend sind, um einen Austritt von Kältemittel aus dem Verdampfer 7 und den Leitungen 8, 9 ins Freie zu verhindern.Below the evaporator 7, a collecting channel 11 for condensate running off the evaporator 7 is formed on the rear wall of the inner space 6. A drain line 12 is led out from a lowest point of the gutter 11, starting at the back of the body 4 and ends like the lines 8, 9 on the coupling part 10. The coupling part 10 thus has three connector elements, one for each line 8, 9, 12th in which at least the connector elements assigned to the lines 8, 9 are self-closing in the unconnected state of the coupling part 10, in order to prevent escape of refrigerant from the evaporator 7 and the lines 8, 9 into the open.

Eine zweite Nische 13 des Einbauschranks 1, unterhalb der die erste Baugruppe 3 aufnehmenden Nische 2, enthält hier zwei Schubladen 14. Die Nische 13 ist nicht gekühlt. Ihre Tiefe ist etwas geringer als die der Nische 2, so dass zwischen einer Rückwand 15 der Nische 13 und einer Wand 16, an der der Einbauschrank 1 aufgestellt ist, ein Schacht 17 frei bleibt, der die Nische 2 mit einem Sockelhohlraum 18 des Schranks 1 verbindet.A second niche 13 of the built-in cupboard 1, below the niche 2 receiving the first assembly 3, contains here two drawers 14. The niche 13 is not cooled. Their depth is slightly less than that of the niche 2, so that between a rear wall 15 of the niche 13 and a wall 16, where the built-in wardrobe 1 is placed, a shaft 17 remains free, the niche 2 with a base cavity 18 of the cabinet. 1 combines.

In dem Sockelhohlraum 18 ruht eine zweite Baugruppe 19 des Kältegeräts z.B. unmittelbar über dem Fußboden. Diese zweite Baugruppe 19 umfasst einen Verdichter 20, eine Saugleitung 21 und eine Druckleitung 22, die den Verdichter 20 jeweils mit einem zweiten Kupplungsteil 23 verbinden, einen in die Druckleitung 22 eingefügten Verflüssiger 24 und einen Ventilator 25, der als Zwangsbelüftung für den Verdichter und den Verflüssiger 24 dient.In the base cavity 18 rests a second assembly 19 of the refrigerator, for example, directly above the floor. This second assembly 19 comprises a compressor 20, a suction line 21 and a pressure line 22 which connect the compressor 20 each with a second coupling part 23, one inserted into the pressure line 22 Condenser 24 and a fan 25, which serves as forced ventilation for the compressor and the condenser 24.

Die zwei Kupplungsteile 10, 23 verbinden die Ablaufleitung 9 mit der Saugleitung 21, die Zulaufleitung 8 mit der Druckleitung 22 und die Abflussleitung 12 mit einer Ablaufleitung 26, die auf eine auf dem Verdichter 20 montierte Verdunstungsschale 27 mündet.The two coupling parts 10, 23 connect the drain line 9 with the suction line 21, the feed line 8 with the pressure line 22 and the drain line 12 with a drain line 26, which opens onto a mounted on the compressor 20 evaporation tray 27.

Auch bei dem zweiten Kupplungsteil 23 sind die den Kältemittel führenden Leitungen 21, 22 zugeordneten Verbinderelemente im unverbundenen Zustand selbstschließend.In the case of the second coupling part 23 too, the lines 21, 22 associated with the refrigerant are self-closing in the unconnected state.

Das erfindungsgemäße Kältegerät wird vom Hersteller in Form der zwei nicht miteinander verbundenen Baugruppen 3 und 19 ausgeliefert. Die Montage erfolgt, indem die erste Baugruppe 3 in von einem herkömmlichen Kühlschrank gewohnter Weise in der Nische 2 platziert wird und die Baugruppe 19 in den Sockelhohlraum 18 eingeschoben wird, z.B. von vorne, nachdem eine vordere Blende 28 des Sockelhohlraums zeitweilig entfernt worden ist. Zu einem geeigneten Zeitpunkt werden die zwei Kupplungsteile 10, 23 zusammengefügt, z.B., indem - eine ausreichende Länge der Leitungen 8, 9, 12 vorausgesetzt - nach dem Platzieren der ersten Baugruppe 3 und dem Durchführen der Leitungen 8, 9, 12 und des Kupplungsteils 10 durch den Schacht 17 das Kupplungsteil 10 durch den Sockelhohlraum 17 nach vorne heraus gezogen und mit dem Kupplungsteil 23 zusammengefügt wird, bevor die zweite Baugruppe 19 an ihren Platz geschoben wird.The refrigeration device according to the invention is supplied by the manufacturer in the form of two unconnected assemblies 3 and 19. Assembly is accomplished by placing the first assembly 3 in the niche 2 in a manner conventional in a conventional refrigerator and inserting the assembly 19 into the socket cavity 18, e.g. from the front, after a front panel 28 of the base cavity has been temporarily removed. At an appropriate time, the two coupling parts 10, 23 are joined together, for example by providing a sufficient length of the lines 8, 9, 12 after placing the first assembly 3 and passing through the lines 8, 9, 12 and the coupling part 10 is pulled through the shaft 17, the coupling member 10 through the base cavity 17 to the front out and assembled with the coupling member 23 before the second assembly 19 is pushed into place.

Die erfindungsgemäße Trennung der zwei Baugruppen 3 und 19 erlaubt es, gleichzeitig das Gehäuse in einer für einen Benutzer bequem zugänglichen Höhe anzubringen und den herkömmlicherweise ungenutzten Sockelhohlraum des Einbauschranks 1 für die Unterbringung der zweiten Baugruppe 19 zu nutzen. Dadurch wird im Vergleich mit den eingangs beschriebenen herkömmlichen Bauformen von Kältegeräten in der Nische 2 ein Volumen von ca. 20 Liter frei. D.h. die Einbaunische kann bei gleichbleibenden Volumen des Innenraums 6 entsprechend diesen 20 Litern in der Höhe reduziert werden, wodurch zusätzlicher Platz in dem Einbauschrank 1 für andere Zwecke geschaffen wird, oder es kann bei unveränderten Abmessungen der Nische 2 der Innenraum 6 des Kältegeräts entsprechend vergrößert werden.The separation of the two assemblies 3 and 19 according to the invention makes it possible at the same time to install the housing in a convenient height for a user and to use the conventionally unused base cavity of the built-in cabinet 1 for accommodating the second module 19. As a result, a volume of about 20 liters is released in comparison to the conventional designs of refrigerators in the niche 2 described above. That is, the installation niche can be reduced at the same volume of the interior 6 corresponding to these 20 liters in height, creating additional space in the built-in wardrobe 1 is created for other purposes, or it can be increased according to unchanged dimensions of the niche 2 of the interior 6 of the refrigerator ,

Selbstverständlich ist es nicht erforderlich, die zwei Baugruppen 3, 19 des erfindungsgemäßen Kältegeräts übereinander in einem Einbauschrank zu montieren. Es ist auch eine je nach verfügbarem Platz seitlich versetzte Anordnung denkbar. Es ist auch möglich, die zweite Baugruppe 19 oberhalb der ersten Baugruppe 3 anzuordnen, etwa in einem deckennahen Bereich eines Einbauschranks, der für einen Benutzer im Allgemeinen ebenfalls schlecht zugänglich ist. In einem solchen Fall wäre zweckmäßigerweise in der Ablaufleitung 9 oder 26 eine Pumpe vorzusehen, um das aus dem Innenraum 6 ablaufende Kondenswasser auf das Niveau der Verdunstungsschale 27 anzuheben.Of course, it is not necessary to mount the two modules 3, 19 of the refrigerator according to the invention one above the other in a built-in closet. It is also conceivable depending on the available space laterally offset arrangement. It is also possible to arrange the second subassembly 19 above the first subassembly 3, for example in an area near the ceiling of a built-in cabinet, which is likewise generally inaccessible to a user. In such a case, a pump would be expediently provided in the drain line 9 or 26 in order to raise the condensate running out of the interior 6 to the level of the evaporation tray 27.
