Description

Die Erfindung betrifft ein Kühl- und/oder Gefriergerät mit einem Gerätekorpus, der wärmeisolierende Wandungen aufweist, die einen Innenraum umschließen, sowie mit einem Kältemittelkreislauf, der als Komponenten einen Kompressor, einen Verflüssiger, eine Drossel und einen Verdampfer umfasst. Die Erfindung betrifft ferner ein Verfahren zur Herstellung eines derartigen Kühl- und/oder Gefriergeräts.The invention relates to a refrigerator and / or freezer with a device body that has heat-insulating walls that enclose an interior space, as well as with a refrigerant circuit that includes a compressor, a condenser, a throttle and an evaporator as components. The invention also relates to a method for producing such a refrigerator and / or freezer.

Es ist bekannt, einzelne Komponenten eines Kühl- und/oder Gefriergerätes auf einem gemeinsamen Träger anzuordnen, um den Zusammenbau und die Wartung von Geräten zu vereinfachen. Dies führt zu einer Vereinfachung in der Herstellung und Wartung der Geräte.It is known to arrange individual components of a refrigerator and / or freezer on a common carrier in order to simplify the assembly and maintenance of devices. This leads to a simplification in the manufacture and maintenance of the devices.

JPH09243234A, JP2007249537A und JPS4894247U offenbaren Kühl- und/oder Gefriergeräte aus dem Stand der Technik.JPH09243234A, JP2007249537A and JPS4894247U disclose prior art refrigerators and / or freezers.

Ferner sind vakuumisolierte Kühlgeräte bekannt, die sich durch einen besonders niedrigen Wärmeverlust auszeichnen, die aber in der Herstellung aufwändig sind und bei denen die Durchführung von Leitungen in den Innenraum des Gerätes mit hohem Aufwand verbunden ist.Furthermore, vacuum-insulated cooling devices are known which are characterized by a particularly low heat loss, but which are complex to manufacture and in which the implementation of lines into the interior of the device is associated with great effort.

Aufgabe der Erfindung ist es, ein Kühl- und/oder Gefriergerät bereitzustellen, welches selbst im Falle einer Vakuumisolation einfach und kostengünstig herzustellen und zu warten ist.The object of the invention is to provide a refrigerator and / or freezer which is simple and inexpensive to manufacture and maintain even in the case of vacuum insulation.

Die Aufgabe wird durch die Merkmale des unabhängigen Vorrichtungsanspruchs 1 sowie durch die Merkmale des unabhängigen Verfahrensanspruchs 10 gelöst.The object is achieved by the features of the independent device claim 1 and by the features of the independent method claim 10.

Vor diesem Hintergrund betrifft die Erfindung ein Kühl- und/oder Gefriergerät mit einem Gerätekorpus, der wärmeisolierende Wandungen aufweist, die einen Innenraum umschließen, sowie mit einem Kältemittelkreislauf, der als Komponenten einen Kompressor, einen Verflüssiger, eine Drossel und einen Verdampfer umfasst. Erfindungsgemäß ist vorgesehen, dass alle Komponenten des Kältemittelkreislaufs gemeinsam auf einem Aggregatträger verbaut sind, das insgesamt vom Gerätekorpus getrennt und aus dem Gerät entnommen werden kann, dass der Aggregatträger einen Maschinenabschnitt und einen damit verbundenen Verdampferabschnitt umfasst, wobei der Kompressor sowie der Verflüssiger im Maschinenabschnitt und der Verdampfer im Verdampferabschnitt aufgenommen sind und dass der Aggregatträger einen Verbindungskanal aufweist, in dem alle zwischen dem Maschinenabschnitt und dem Verdampferabschnitt verlaufende Kabel und/oder Leitungen aufgenommen sind, wobei in dem Verbindungskanal eine Tauwasserleitung aufgenommen ist.Against this background, the invention relates to a refrigerator and / or freezer with a device body that has heat-insulating walls that enclose an interior space, as well as with a refrigerant circuit that includes a compressor, a condenser, a throttle and an evaporator as components. According to the invention, it is provided that all components of the refrigerant circuit are installed together on a unit carrier that can be separated from the device body and removed from the device, that the unit carrier comprises a machine section and an evaporator section connected to it, the compressor and the condenser in the machine section and the evaporator are accommodated in the evaporator section and that the unit carrier has a connection channel in which all cables and / or lines running between the machine section and the evaporator section are accommodated, a condensate line being accommodated in the connection channel.

Es ist somit vorgesehen, dass ein Aggregatträger mit allen Komponenten des Kältemittelkreislaufs insgesamt vom Gerätekorpus getrennt werden kann. Dies schließt auch die Rohrleitungen und etwaige weitere Komponenten des Kältemittelkreislaufs wie Trockner oder Sammler mit ein. Dies ist insbesondere deshalb bemerkenswert, da sowohl Komponenten der warmen Seite des Kältemittelkreislaufs, also Kompressor und Verflüssiger, als auch Komponenten der kalten Seite des Kältemittelkreislaufs, also der Verdampfer, gemeinsam auf einem Aggregatträger verbaut sind, das insgesamt vom Gerätekorpus getrennt und aus dem Kühlgerät entnommen werden kann. Entsprechend können bei der Zusammensetzung des Gerätes diese Komponenten auch in einem einzigen Arbeitsschritt durch Einsetzen des Aggregatträgers im Gerät verbaut werden. Eine Vereinfachung ergibt sich auch bei der Durchführung allfälliger Reparaturarbeiten. Diese Vereinfachungen gehen über die mit den aus dem Stand der Technik bekannten Maßnahmen erreichbaren Vereinfachungen hinaus.It is therefore provided that an assembly carrier with all components of the refrigerant circuit can be separated from the device body as a whole. This also includes the pipes and any other components of the refrigerant circuit such as dryers or collectors. This is particularly noteworthy because both components of the warm side of the refrigerant circuit, i.e. the compressor and condenser, and components of the cold side of the refrigerant circuit, i.e. the evaporator, are installed together on a unit carrier that is separated from the unit body and removed from the cooling unit can be. Correspondingly, when assembling the device, these components can also be installed in a single work step by inserting the assembly carrier in the device. There is also a simplification when carrying out any repair work. These simplifications go beyond the simplifications that can be achieved with the measures known from the prior art.

Der lösbar mit dem Gerätekorpus in Verbindung stehende Aggregatträger kann beispielweise anhand von Schraubverbindungen befestigt sein. Beispielsweise kann auch vorgesehen sein, dass der Aggregatträger werkzeugfrei vom Gerätekorpus gelöst werden kann und beispielsweise lediglich anhand von Rastverbindungen mit diesem in Verbindung steht.The unit carrier, which is detachably connected to the device body, can be fastened, for example, by means of screw connections. For example, it can also be provided that the unit carrier can be detached from the device body without tools and, for example, is only connected to it by means of latching connections.

Der Verbindungskanal kann vollständig von Abschnitten des Aggregatträgers umschlossen sein oder zumindest einseitig und/oder zumindest abschnittsweise frei liegen. Nachdem alle zwischen dem Maschinenabschnitt und dem Verdampferabschnitt verlaufenden Kabel und/oder Leitungen und vorzugsweise generell alle in den Innenraum des Geräts führenden Leitungen in dem Verbindungskanal aufgenommen sind, kann auf Kabel- oder Leitungsdurchführungen durch die wärmeisolierenden Wandungen des Gerätekorpus verzichtet werden. Dies ist vorteilhaft, da derartige Durchführungen Wärmebrücken darstellen. Insbesondere vorteilhaft ist dies bei einer Vakuumisolation, da derartige Durchführungen das Risiko von Undichtigkeiten im Vakuumisolationskörper erhöhen. Diese Anordnung ermöglicht auch eine einfache Montage der Leitungen und Anschlüsse. Die Kabel bzw. Leitungen können innerhalb des Verbindungskanals mit ausreichendem seitlichem Abstand verlegt werden.The connecting channel can be completely enclosed by sections of the unit carrier or can be exposed at least on one side and / or at least in sections. After all of the cables and / or lines running between the machine section and the evaporator section and preferably generally all of the lines leading into the interior of the device are accommodated in the connecting duct, there is no need for cable or line bushings through the heat-insulating walls of the device body. This is advantageous since such feedthroughs represent thermal bridges. This is particularly advantageous in the case of vacuum insulation, since such bushings increase the risk of leaks in the vacuum insulation body. This arrangement also enables simple assembly of the lines and connections. The cables or lines can be laid within the connecting duct with sufficient lateral clearance.

In einer Ausführungsform ist vorgesehen, dass der Verbindungskanal zumindest abschnittsweise wärmeisoliert ist. Vorzugsweise ist der Verbindungskanal im Wesentlichen über seine gesamte Länge wärmeisoliert. Zu diesem Zweck kann im Aggregatträger und vorzugsweise im Verdampferabschnitt des Aggregatträgers Wärmeisolationsmaterial vorgesehen sein, das entlang dem Verbindungskanal angeordnet ist.In one embodiment it is provided that the connection channel is thermally insulated at least in sections. The connecting duct is preferably thermally insulated over its entire length. For this purpose, heat insulation material can be provided in the unit carrier and preferably in the evaporator section of the unit carrier, which is arranged along the connecting channel.

Der Verbindungskanal kann zumindest abschnittsweise in einem Bereich des Aggregatträgers verlaufen, der an eine wärmeisolierende Wandung des Gerätekorpus grenzt. Beispielsweise kann der Verbindungskanal entlang der Unterseite des Verdampferabschnitts verlaufen, wodurch seine Außenseite an oder nahe dem wärmeisolierenden Boden des Innenraums verläuft. Eine Wärmeisolierung des Verbindungskanals kann daher zumindest teilweise auch durch die Dämmeigenschaften des wärmeisolierenden Bodens des Innenraums erreicht werden.The connecting channel can run at least in sections in an area of the unit carrier which borders on a heat-insulating wall of the device body. For example, the connection channel can run along the underside of the evaporator section, whereby its outside at or near the heat insulating Floor of the interior runs. Thermal insulation of the connecting channel can therefore also be achieved, at least in part, by the insulating properties of the heat-insulating floor of the interior.

In einer Ausführungsform ist vorgesehen, dass in dem Verbindungskanal ein Saugrohr und/oder eine Kapillare des Kältemittelkreislaufs aufgenommen sind. Erfindungsgemäß ist in dem Verbindungskanal eine Tauwasserleitung aufgenommen. Bei der Drossel des Kältemittelkreislaufs kann es sich um eine Kapillare handeln, die durch den Verbindungskanal geführt wird. Zum Wärmetausch kann die Kapillare auch innerhalb des Verbindungskanals zumindest abschnittsweise um das Saugrohr gewickelt sein. Überhaupt kann innerhalb des vorzugsweise wärmeisolierten Verbindungskanals ein starker Wärmetausch zwischen Kapillare und Saugrohr stattfinden, was sich günstig auf die Energieeffizienz des Geräts auswirkt. Bei der Tauwasserleitung kann es sich um eine Schlauchdurchführung handeln.In one embodiment it is provided that a suction pipe and / or a capillary of the refrigerant circuit are received in the connecting channel. According to the invention, a condensate line is received in the connecting channel. The throttle of the refrigerant circuit can be a capillary that is passed through the connecting channel. For heat exchange, the capillary can also be wound around the suction tube at least in sections within the connecting channel. In general, a strong heat exchange between capillary and suction tube can take place within the preferably thermally insulated connection channel, which has a favorable effect on the energy efficiency of the device. The condensate line can be a hose feed-through.

In einer weiteren Ausführungsform ist vorgesehen, dass der Gerätekorpus eine Vollvakuumdämmung aufweist, wobei der Innenraum von einem einteiligen, kistenförmigen Vakuumisolationskörper umgeben ist. Die wärmeisolierenden Wandungen des Gerätekorpus sind in dieser Ausführungsform Abschnitte des Vakuumisolationskörpers. Es kann vorgesehen sein, dass der Vakuumisolationskörper eine Barrierefolie und ein im von der Barrierefolie eingeschlossenen Kern angeordnetes Stützmaterial umfasst.In a further embodiment it is provided that the device body has full vacuum insulation, the interior space being surrounded by a one-piece, box-shaped vacuum insulation body. The heat-insulating walls of the device body are sections of the vacuum insulation body in this embodiment. It can be provided that the vacuum insulation body comprises a barrier film and a support material arranged in the core enclosed by the barrier film.

Ferner kann der Gerätekorpus eine Rahmenunterkonstruktion aufweisen, welche sich über die gesamte Höhe des Gerätes erstreckt und den Bereich des Innenraums ebenso umgibt wie einen Sockelbereich ausbildet. Der kistenförmige Vakuumisolationskörper kann in diese Rahmenkonstruktion eingesetzt werden. Die Rahmenunterkonstruktion kann ferner zur Aufnahme des Aggregatträgers dienen. Sie kann auch den Boden des Gerätekorpus ausbilden. Sie verleiht dem Gerätekorpus Stabilität.Furthermore, the device body can have a frame substructure which extends over the entire height of the device and surrounds the area of the interior space as well as forming a base area. The box-shaped vacuum insulation body can be used in this frame construction. The frame substructure can also serve to accommodate the assembly carrier. You can also form the bottom of the device body. It gives the device body stability.

Um den Vakuumisolationskörper zu schützen, kann vorgesehen sein, diesen vollständig zu kaschieren. Zum einen kann dabei vorgesehen sein, dass in den kistenförmigen Vakuumisolationskörper ein Kunststoffinnenbehälter eingesetzt ist. Ferner kann vorgesehen sein, dass die Außenseite der Rahmenunterkonstruktion mit Wandplatten und vorzugsweise Wandblechen verschalt ist. Die Verbindung zwischen den Wandplatten, dem Innenbehälter, dem Vakuumisolationskörper und der Rahmenunterkonstruktion kann durch Verkleben, Verschrauben, Verrasten und vorzugsweise eine Kombination daraus erfolgen.In order to protect the vacuum insulation body, it can be provided that it is completely concealed. On the one hand, it can be provided that a plastic inner container is inserted into the box-shaped vacuum insulation body. Furthermore, it can be provided that the outside of the frame substructure is clad with wall panels and preferably wall sheets. The connection between the wall panels, the inner container, the vacuum insulation body and the frame substructure can be made by gluing, screwing, locking and preferably a combination thereof.

In einer Ausführungsform ist vorgesehen, dass der Aggregatträger im unteren Bereich des Gerätekorpus verbaut ist. Durch den Einbau der schweren Komponenten des Kältemittelkreislaufs in den unteren (Sockel-)Bereich des Geräts ergibt sich eine hohe Standsicherheit. Ferner ergibt sich durch einen tiefen Einbau eine bessere Ergonomie für den Kunden, da weiter obenliegende Fächer besser zugänglich sind und der schlechter zugängliche Bereich im Sockelbereich des Gerätes durch den Aggregatträger eingenommen wird. Letztlich kann allfälliges Tauwasser einfach nach unten abfließen.In one embodiment it is provided that the unit carrier is installed in the lower area of the device body. The installation of the heavy components of the refrigerant circuit in the lower (base) area of the device results in a high level of stability. Furthermore, a deep installation results in better ergonomics for the customer, since the compartments higher up are more accessible and the less accessible area in the base area of the device is taken up by the unit carrier. Ultimately, any condensation can simply flow downwards.

Denkbar ist es weiterhin, dass eine oder mehrere Komponenten ausgewählt aus der Gruppe eines Maschinenraumventilators, eines Kühlraumventilators, einer Steuereinheit, einer Tauwasserschale und eines Netzteils mit Verkabelung auf dem Aggregatträger verbaut sind. Dies führt zu einer weiteren Vereinfachung bei der Zusammensetzung des Geräts und zu einer Vereinfachung bei der Durchführung allfälliger Reparaturarbeiten. Komponenten der warmen Seite des Kältemittelkreislaufs wie ein Maschinenraumventilator, eine Steuereinheit, eine Tauwasserschale oder ein Netzteil mit Verkabelung sind in diesem Fall im Maschinenabschnitt und Komponenten der kalten Seite des Kältemittelkreislaufs wie ein Kühlraumventilator im Verdampferabschnitt anzuordnen. Der Verbindungskanal kann in diesem Fall auch alle Kabel und/oder Leitungen aufnehmen, die aufgrund dieser weiteren am Aggregatträger verbauten Bauteile zusätzlich zwischen Maschinenabschnitt und Verdampferabschnitt verlaufen müssen. Beispielsweise kann im Verbindungskanal eine Versorgungsleitung eines Kühlraumventilators verlaufen.It is also conceivable that one or more components selected from the group of a machine room fan, a cold room fan, a control unit, a condensate tray and a power supply unit with cabling are installed on the unit carrier. This leads to a further simplification in the assembly of the device and to a simplification in the implementation of any repair work. In this case, components on the warm side of the refrigerant circuit such as a machine room fan, a control unit, a condensate tray or a power supply unit with cabling are to be arranged in the machine section and components on the cold side of the refrigerant circuit such as a cold room fan in the evaporator section. In this case, the connecting duct can also accommodate all cables and / or lines which, due to these additional components installed on the unit carrier, must also run between the machine section and the evaporator section. For example, a supply line of a cooling chamber fan can run in the connecting channel.

In einer Ausführungsform ist vorgesehen, dass in einem neben der Verbindung liegenden Freiraum zwischen dem Maschinenabschnitt und dem Verdampferabschnitt eine zum Gerätekorpus gehörige Wärmeisolationsschicht angeordnet ist. Bei der Wärmeisolationsschicht kann es sich um einen Teilabschnitt der Vollvakuumdämmung handeln. Die Verbindung kann beispielsweise durch einen im vorderen Bereich des Geräts verlaufenden Steg gebildet werden, der zum Maschinenabschnitt oder dem Verdampferabschnitt gehört oder durch ein separates Zwischenstück gebildet wird. In diesem Fall kann der Boden des gekühlten Innenraums beziehungsweise können der den Innenraumboden ausbildende Abschnitt des Vakuumisolationskörpers und des Innenbehälters gegenüber der Öffnungsebene des Innenraums etwas zurückversetzt sein. Die Wärmeisolationsschicht ist Teil des Gerätekorpus und füllt eine Freilassung des Aggregatträgers zwischen Maschinenabschnitt und Verdampferabschnitt und neben dem Verbindungselement aus. Die Verbindung selbst kann ebenfalls Dämmmaterial umfassen, um auch in diesem Bereich die Ausbildung eine Wärmebrücke zu vermeiden.In one embodiment it is provided that a heat insulation layer belonging to the device body is arranged in a free space lying next to the connection between the machine section and the evaporator section. The thermal insulation layer can be a section of the full vacuum insulation. The connection can be formed, for example, by a web running in the front area of the device, which belongs to the machine section or the evaporator section or is formed by a separate intermediate piece. In this case, the bottom of the cooled interior or the section of the vacuum insulation body and the inner container forming the interior bottom can be set back somewhat with respect to the opening plane of the interior. The thermal insulation layer is part of the body of the device and fills an area in the subframe between the machine section and the evaporator section and next to the connecting element. The connection itself can also comprise insulating material in order to avoid the formation of a thermal bridge in this area as well.

Gemäß einer weiteren Ausführungsform ist der Maschinenabschnitt in einem Sockelraum des Gerätekorpus und der Verdampferabschnitt im untersten Bereich des Innenraums aufgenommen. In diesem Fall liegt der Maschinenabschnitt unterhalb des Verdampferabschnitts. Vorzugsweise ist der Maschinenabschnitt so dimensioniert, dass es den Sockelraum des Gerätekorpus vollständig ausfüllt und der Verdampferabschnitt so dimensioniert, dass es den untersten Bereich des wärmeisolierten Innenraums derart vollständig einnimmt, dass der Boden und die untersten Abschnitte der Rückwand und gegebenenfalls auch der Seitenwände des Innenraums vollständig vom Verdampferabschnitt überdeckt werden. Vorzugsweise ist der Sockelraum wie auch der Innenraum nach vorne hin geöffnet, sodass der Aggregatträger im Falle einer Demontage nach vorne aus dem Gerätekorpus gezogen werden kann und, im Umkehrschluss, bei der Montage von vorne in den Gerätekorpus eingeschoben werden kann.According to a further embodiment, the machine section is accommodated in a base space of the device body and the evaporator section is accommodated in the lowermost area of the interior. In this case, the machine section is below the evaporator section. The machine section is preferably dimensioned so that it completely fills the base space of the device body and the evaporator section is dimensioned such that it completely occupies the lowest area of the heat-insulated interior in such a way that the bottom and the lowermost sections of the rear wall and possibly also the side walls of the interior completely be covered by the evaporator section. The base space as well as the interior are preferably open towards the front so that the unit carrier can be pulled forwards out of the device body in the event of dismantling and, conversely, can be pushed into the device body from the front during assembly.

Vor dem eingangs genannten Hintergrund betrifft die Erfindung ferner ein Verfahren zur Herstellung eines erfindungsgemäßen Kühl- und/oder Gefriergeräts, wobei der Aggregatträger als Ganzes in den Gerätekorpus eingesetzt wird. Vorzugsweise wird der Aggregatträger von vorne den Gerätekorpus eingeschoben. Vorzugsweise wird der Aggregatträger in einen unteren Bereich des Gerätekorpus eingesetzt.Against the background mentioned at the beginning, the invention also relates to a method for producing a refrigerator and / or freezer according to the invention, the assembly carrier being inserted as a whole into the device body. The unit carrier is preferably pushed into the device body from the front. The unit carrier is preferably used in a lower area of the device body.

An dieser Stelle wird darauf hingewiesen, dass die Begriffe "ein" und "eine" nicht zwingend auf genau eines der Elemente verweisen, wenngleich dies eine mögliche Ausführung darstellt, sondern auch eine Mehrzahl der Elemente bezeichnen können. Ebenso schließt die Verwendung des Plurals auch das Vorhandensein des fraglichen Elementes in der Einzahl ein und umgekehrt umfasst der Singular auch mehrere der fraglichen Elemente.At this point it should be noted that the terms “a” and “an” do not necessarily refer to exactly one of the elements, although this represents a possible embodiment, but can also designate a plurality of the elements. The use of the plural also includes the presence of the element in question in the singular, and conversely, the singular also includes several of the elements in question.

Der Gerätekorpus 200 umfasst eine Rahmenunterkonstruktion, welche im untersten Bereich einen Sockelraum 210 mit dem Geräteboden ausbildet und in welcher im darüberliegenden Bereich ein kistenförmiger Vakuumisolationskörper aufgenommen ist, der einen Innenraum 220 definiert. Der Vakuumisolationskörper dient als Wärmeisolation für den Innenraum 220 und umfasst eine Barrierefolie und ein im von der Barrierefolie eingeschlossenen Kern angeordnetes Stützmaterial. Er ist rundum kaschiert, um die Barrierefolie zu schützen. In die Innenraumöffnung des Vakuumisolationskörpers ist ein Kunststoffinnenbehälter eingesetzt. An der Außenseite ist die Rahmenunterkonstruktion mit einem Deckenblech, einem Rückwandblech und mit zwei Seitenwandblechen kaschiert. Der den Innenraumboden 221 ausbildende Abschnitt des Vakuumisolationskörpers und des Innenbehälters sind gegenüber der Öffnungsebene des Innenraums etwas zurückversetzt.The device body 200 comprises a frame substructure which forms a base space 210 with the device base in the lowest region and in which a box-shaped vacuum insulation body is received in the region above, which defines an interior space 220. The vacuum insulation body serves as thermal insulation for the interior space 220 and comprises a barrier film and a support material arranged in the core enclosed by the barrier film. It is laminated all around to protect the barrier film. A plastic inner container is inserted into the interior opening of the vacuum insulation body. On the outside, the frame substructure is covered with a ceiling panel, a rear panel and two side panels. The section of the vacuum insulation body and of the inner container forming the interior floor 221 are set back somewhat with respect to the opening plane of the interior.

Der Aggregatträger 100 umfasst einen Maschinenabschnitt 110 und ein damit verbundener Verdampferabschnitt 120. Der Maschinenabschnitt 110 bildet den unteren Teil des Aggregatträgers 100 aus und ist so dimensioniert, dass es von vorne in den Sockelraum 210 des Gerätekorpus 200 eingeschoben werden kann und diesen vollständig einnimmt. Der Verdampferabschnitt 120 ist auf den Maschinenabschnitt 110 aufgesetzt und so dimensioniert, dass es von vorne in den untersten Bereich des wärmeisolierten Innenraums 220 des Gerätekorpus 200 eingeschoben werden kann und diesen vollständig einnimmt, sodass der Boden 221 und die untersten Abschnitte der Seitenwände und der Rückwand 222 des Innenraums 220 vollständig vom Verdampferabschnitt 120 überdeckt sind. Der Maschinenabschnitt 110 und der Verdampferabschnitt 120 sind nur anhand eines Verbindungsstegs 130 verbunden, der sich im vorderen Bereich des Aggregatträgers 100 befindet. Hinter dem Verbindungssteg 130 ist im Aggregatträger 100 zwischen Maschinenabschnitt 110 und Verdampferabschnitt 120 eine Aussparung 140 vorgesehen, in welcher der vakuumisolierte Boden 221 des Gerätekorpus 200 Platz finden kann, wenn der Aggregatträger 100 derart von vorne in den Gerätekorpus 200 eingeschoben wird, dass der Maschinenabschnitt 110 in den Sockelraum 210 und der Verdampferabschnitt 120 in den Innenraum 220 des Gerätekorpus 200 geschoben werden.The unit carrier 100 comprises a machine section 110 and an evaporator section 120 connected to it. The machine section 110 forms the lower part of the unit carrier 100 and is dimensioned so that it can be pushed into the base space 210 of the device body 200 from the front and occupies it completely. The evaporator section 120 is placed on the machine section 110 and dimensioned so that it can be pushed into the lowermost area of the heat-insulated interior 220 of the device body 200 from the front and occupies this completely, so that the bottom 221 and the lowermost sections of the side walls and the rear wall 222 of the interior 220 are completely covered by the evaporator section 120. The machine section 110 and the evaporator section 120 are only connected by means of a connecting web 130, which is located in the front region of the unit carrier 100. Behind the connecting web 130, a recess 140 is provided in the unit carrier 100 between the machine section 110 and the evaporator section 120, in which the vacuum-insulated floor 221 of the device body 200 can find space when the unit carrier 100 is pushed into the device body 200 from the front in such a way that the machine section 110 can be pushed into the base space 210 and the evaporator section 120 into the interior 220 of the device body 200.

Im Maschinenabschnitt 110 sind ein Kompressor 111 und ein Verflüssiger 112 angeordnet, wobei sich der Kompressor 111 im hinteren Bereich und der Verflüssiger 112 im vorderen Bereich des Maschinenabschnitts 110 befinden. Ferner ist im vorderen Bereich des Maschinenabschnitts 110 in thermischem Kontakt mit dem Verflüssiger 112 eine Tauwasserschale 113 angeordnet. Der Kompressor 111 ist mit einer gefederten Aufhängung 114 im hinteren Bereich des Maschinenabschnitts 110 verbaut. An der Vorderseite des Maschinenabschnitts 110 befindet sich eine mit Luftleitelementen verblendete Öffnung 115 für Kühlluft und mehrere Stege im Maschinenabschnitt 110 bilden einen Kühlluftkanal aus, durch den Kühlluft ausgehend von der Öffnung 115 über den Verflüssiger 112 mit der zugeordneten Tauwasserschale 113 und den Kompressor 111 wieder zurück zur Öffnung 115 strömen kann. Die Rückseite 211 des Sockelraums 210 ist durch den Wandabschnitt 211 verschlossen. An der Vorderseite des Maschinenabschnitts 110 befindet sich des Weiteren ein Lagerstift 116 für eine Gerätetüre. Ebenfalls im Maschinenabschnitt 110 angeordnet sind ein Kühlluftventilator und eine Steuereinheit, die aber in der Figur aus Gründen der Übersichtlichkeit nicht gesondert dargestellt sind. Auch eine im Maschinenabschnitt angeordnete elektrische Verkabelung mit Netzteil, die durch die Begrenzung des Sockelraums 210 des Gerätekorpus 200 an eine Stromversorgung angeschlossen werden kann, ist in der Figur nicht näher dargestellt.A compressor 111 and a condenser 112 are arranged in the machine section 110, the compressor 111 being located in the rear area and the condenser 112 being located in the front area of the machine section 110. Furthermore, a condensate tray 113 is arranged in the front region of the machine section 110 in thermal contact with the condenser 112. The compressor 111 is installed with a sprung suspension 114 in the rear region of the machine section 110. On the front of the machine section 110 there is an opening 115 for cooling air, covered with air guiding elements, and several webs in the machine section 110 form a cooling air duct through which cooling air, starting from the opening 115, returns via the condenser 112 with the associated condensation tray 113 and the compressor 111 can flow to opening 115. The rear side 211 of the base space 210 is closed by the wall section 211. On the front of the machine section 110 there is also a bearing pin 116 for an appliance door. A cooling air fan and a control unit are also arranged in the machine section 110, but are not shown separately in the figure for reasons of clarity. Electrical cabling with a power supply unit, which is arranged in the machine section and which can be connected to a power supply due to the delimitation of the base space 210 of the device body 200, is also not shown in detail in the figure.

Im Verdampferabschnitt 120 ist ein Kaltluftkanal 121 ausgebildet, der sich von einer Ansaugöffnung 122 bis zu einer Auslassöffnung 123 erstreckt. Innerhalb des Kaltluftkanals befindet sich der Verdampfer 128. Die Ansaugöffnung 122 befindet sich am vorderen Ende des Verdampferabschnitts 120. Die Auslassöffnung 123 befindet sich am hinteren Ende des Verdampferabschnitts 120 und grenzt im eingebauten Zustand des Aggregatträgers 100 an die Rückwand 222 des Gerätekorpus 200. Im Bereich nahe der Auslassöffnung 123 ist der Kaltluftkanal 121 erweitert und bildet einen Ventilatorraum 124 aus, in dem ein Verdampferventilator 125 angeordnet ist. Das hintere Endstück der oberen Verblendung 126 des Ventilatorraums 124 zeigt senkrecht nach oben und reicht nicht ganz bis zum hinteren Ende des Verdampferabschnitts, sodass im eingebauten Zustand des Aggregatträgers 100 zwischen dem hinteren Endstück der oberen Verblendung 126 des Ventilatorraums 124 und der Rückwand 222 des Gerätekorpus 200 ein senkrechter Kanalabschnitt ausgebildet wird, der in einen nicht näher dargestellten vertikalen Luftführungskanal im weiter oben liegenden Bereich der Rückwand des 222 mündet.A cold air duct 121 is formed in the evaporator section 120 and extends from a suction opening 122 to an outlet opening 123. The evaporator 128 is located inside the cold air duct. The suction opening 122 is located at the front end of the evaporator section 120. The outlet opening 123 is located at the rear end of the evaporator section 120 and, when the unit carrier 100 is installed, is adjacent to the rear wall 222 of the device body 200 the cold air duct 121 is widened near the outlet opening 123 and forms a fan chamber 124 in which an evaporator fan 125 is arranged. The rear end piece of the upper cover 126 of the fan chamber 124 points vertically upwards and does not extend all the way to the rear end of the evaporator section, so that in the installed state of the assembly support 100 between the rear end piece of the upper cover 126 of the fan chamber 124 and the rear wall 222 of the device body 200, a vertical channel section is formed which opens into a vertical air duct, not shown in detail, in the area of the rear wall of the 222 located further up.

Der Aggregatträger 100 weist im Bereich des Verdampferabschnitts 120 und des Verbindungsstegs 120 ferner einen Verbindungskanal 150 auf, in dem alle zwischen dem Maschinenabschnitt 110 und dem Verdampferabschnitt 120 verlaufenden Kabel und Leitungen 151 aufgenommen sind. Der Verbindungskanal 150 ist vollständig von Gehäuseteilen des Aggregatträgers 110 umschlossen. Er ist im Wesentlichen über seine gesamte Länge wärmeisoliert. Zu diesem Zweck ist einerseits im Verdampferabschnitt 120 des Aggregatträgers 110 Wärmeisolationsmaterial vorgesehen. Andererseits verläuft der Verbindungskanal ausgehend von der Rückseite des Verdampferabschnitts 120 entlang der Unterseite des Verdampferabschnitts 120 und grenzt somit an einer Seite an den wärmeisolierenden Boden 221 des Innenraums 220 des Gerätekorpus 200. Die Wärmeisolierung des Verbindungskanals 150 wird daher auch durch die Dämmeigenschaften des wärmeisolierenden Bodens 221 des Innenraums 220 des Gerätekorpus 200 erreicht. Die im Verbindungskanal 150 verlaufenden Leitungen 151 sind aus Gründen der Übersichtlichkeit in der Figur nur gesammelt und nicht einzeln dargestellt. Unter ihnen befinden sich aber das Saugrohr und die Kapillare des Kältemittelkreislaufs, wobei die Kapillare innerhalb des wärmeisolierten Verbindungskanals 150 um das Saugrohr gewickelt ist. Ferner verläuft innerhalb des Verbindungskanals 150 ein Tauwasserschlauch, der vom Verdampfer 128 zur Tauwasserschale 113 führt. Des Weiteren verläuft im Verbindungskanal 150 eine Versorgungsleitung, die den Verdampferventilator 125 mit der Steuereinheit und Stromversorgung des Maschinenabschnitts 110 verbindet.In the area of the evaporator section 120 and the connecting web 120, the unit carrier 100 also has a connecting duct 150 in which all cables and lines 151 running between the machine section 110 and the evaporator section 120 are received. The connecting channel 150 is completely enclosed by housing parts of the assembly carrier 110. It is essentially thermally insulated over its entire length. For this purpose, on the one hand, thermal insulation material is provided in the evaporator section 120 of the assembly carrier 110. On the other hand, the connection channel runs from the rear of the evaporator section 120 along the underside of the evaporator section 120 and thus borders on one side of the heat-insulating floor 221 of the interior 220 of the device body 200 of the interior 220 of the device body 200 is reached. For the sake of clarity, the lines 151 running in the connecting channel 150 are only shown collectively in the figure and not shown individually. Below them, however, are the suction pipe and the capillary of the refrigerant circuit, the capillary being wound around the suction pipe within the thermally insulated connecting channel 150. Furthermore, a condensation water hose runs within the connecting channel 150 and leads from the evaporator 128 to the condensation water tray 113. Furthermore, a supply line, which connects the evaporator fan 125 to the control unit and power supply of the machine section 110, runs in the connecting duct 150.
