Definitions
- the present invention relates to a refrigerator and/or freezer with at least one body, which has at least one full-vacuum insulating body and with at least one refrigerated interior arranged in the body, the appliance having at least one refrigerant circuit that serves to cool the interior.
- a full-vacuum insulating body is preferably understood to mean that the body of the device consists of more than 90% of the insulating surface from a continuous vacuum insulating space.
- JP 2007 249537 A discloses a refrigerated vending machine that is easily and inexpensively convertible from chlorofluorocarbon refrigerant operation to carbon dioxide refrigerant operation.
- an existing chlorofluorocarbon refrigerant refrigeration unit is replaced with a new carbon dioxide refrigerant refrigeration unit. Therefore, components other than the existing one Refrigeration equipment for chlorofluorocarbon refrigerant can be reused, and conversion to a vending machine using carbon dioxide refrigerant can be achieved easily and inexpensively.
- a vacuum insulation body in which the outer gas-tight walls are made of sheet metal, forms the main component of the thermal insulation EP 2 778 582 A2 .
- a vacuum-insulated cabinet construction includes panels that are made of sheet metal on the outside and a polymer on the inside. The sheet is coated with a polymeric material and the inner polymeric walls are laminated to this layer. This creates a flat sheet metal blank for forming vacuum cavities. The blank is then bent along fold lines to form a cabinet structure. So at each edge of the cabinet there are two polymer welds and an air-filled gap that together with its two bounding polymer walls form a thermal bridge.
- the object of the present invention is to provide a refrigerator and/or freezer that advantageously develops the prior art described above by its insulation being able to be manufactured with less effort and having greater fail-safety and fewer thermal bridges.
- the full-vacuum insulating body consists at least partially of a film bag, the interior of which is filled with a support material, such as perlite, and the interior of which is vacuum.
- the film bag is designed as an inverted block bottom bag.

Due to the greatly reduced incidence of heat in the cooled interior, the required cooling capacity is reduced and due to the resulting lower heat flows, the requirements for the heat exchanger (evaporator, condenser) of the refrigerant circuit change.

Description
Die vorliegende Erfindung betrifft ein Kühl- und/oder Gefriergerät mit wenigstens einem Korpus, der wenigstens einen Vollvakuumdämmkörper aufweist und mit wenigstens einem in dem Korpus angeordneten, gekühlten Innenraum, wobei das Gerät wenigstens einen Kältemittelkreislauf aufweist, der zur Kühlung des Innenraums dient.The present invention relates to a refrigerator and/or freezer with at least one body, which has at least one full-vacuum insulating body and with at least one refrigerated interior arranged in the body, the appliance having at least one refrigerant circuit that serves to cool the interior.
Dabei wird unter einem Vollvakuumdämmkörper im Rahmen der vorliegenden Erfindung vorzugsweise verstanden, dass der Korpus des Gerätes zu über 90% der Dämmfläche aus einem zusammenhängenden Vakuumdämmraum besteht.In the context of the present invention, a full-vacuum insulating body is preferably understood to mean that the body of the device consists of more than 90% of the insulating surface from a continuous vacuum insulating space.
Aus dem Stand der Technik sind Kühl- und Gefriergeräte mit konventionellen gashaltigen Isolationskörpern aus Polymerschaum bekannt.
Aufgabe der vorliegenden Erfindung ist es, ein Kühl- und/oder Gefriergerät bereitzustellen, das den zuvor beschriebenen Stand der Technik vorteilhaft weiterbildet, indem seine Isolierung mit weniger Aufwand gefertigt werden kann sowie eine höhere Fehlersicherheit und weniger Wärmebrücken aufweist.The object of the present invention is to provide a refrigerator and/or freezer that advantageously develops the prior art described above by its insulation being able to be manufactured with less effort and having greater fail-safety and fewer thermal bridges.
Diese Aufgabe wird mit einem Kühl- und/oder Gefriergerät mit den Merkmalen des Anspruchs 1 und ein Verfahren mit den Merkmalen des Anspruchs 6 gelöst. Vorteilhafte Ausgestaltungen der Erfindung sind in den abhängigen Ansprüchen 2-5 und 7 offenbart.This object is achieved with a refrigerator and/or freezer having the features of claim 1 and a method having the features of claim 6. Advantageous developments of the invention are disclosed in the dependent claims 2-5 and 7.
Erfindungsgemäß besteht der Vollvakuumdämmkörper zumindest teilweise aus einem Folienbeutel, dessen Innenraum mit einem Stützmaterial, wie z.B. Perlit gefüllt ist und in dessen Innenraum Vakuum herrscht. Dabei ist der Folienbeutel als eingestülpter Klotzbodenbeutel ausgeführt.According to the invention, the full-vacuum insulating body consists at least partially of a film bag, the interior of which is filled with a support material, such as perlite, and the interior of which is vacuum. The film bag is designed as an inverted block bottom bag.
Ein solcher Vollvakuumdämmkörper kann sich gemäß der vorliegenden Erfindung nur im Bereich des Korpus befinden oder auch zusätzlich in dem Verschlusselement, d.h. in der Tür, Lade oder Klappe des Gerätes, mittels derer der gekühlte Innenraum verschließbar ist.According to the present invention, such a full-vacuum insulating body can only be located in the area of the body or additionally in the closure element, ie in the door, drawer or flap of the device, by means of which the cooled interior can be closed.
Typischerweise ist die Hülle des Folienbeutels eine diffusionsdichte Umhüllung, mittels derer der Gaseintrag in dem Folienbeutel so stark reduziert ist, dass der gaseintragbedingte Anstieg in der Wärmeleitfähigkeit des entstehenden Vakuumdämmkörpers über dessen Lebensdauer hinweg ausreichend gering ist.Typically, the envelope of the foil bag is a diffusion-tight cover, by means of which the gas entry in the foil bag is reduced to such an extent that the gas entry-related increase in the thermal conductivity of the resulting vacuum insulation body over its service life is sufficiently low.
Als Lebensdauer ist beispielsweise ein Zeitraum von 15 Jahren, vorzugsweise von 20 Jahren und besonders bevorzugt von 30 Jahren anzusetzen. Vorzugsweise liegt der durch Gaseintrag bedingte Anstieg in der Wärmeleitfähigkeit des Vakuumdämmkörpers über dessen Lebensdauer bei < 100 % und besonders bevorzugt bei < 50 %.For example, a period of 15 years, preferably 20 years and particularly preferably 30 years, can be used as the service life. The increase in the thermal conductivity of the vacuum insulating body caused by gas entry over its service life is preferably <100% and particularly preferably <50%.
Vorzugsweise ist die flächenspezifische Gasdurchgangsrate der Umhüllung < 10-5 mbar * I / s *m2 und besonders bevorzugt < 10-6 mbar * I / s *m2 (gemessen nach ASTM D-3985). Diese Gasdurchgangsrate gilt für Stickstoff und Sauerstoff. Für andere Gassorten (insbesondere Wasserdampf) bestehen ebenfalls niedrige Gasdurchgangsraten vorzugweise im Bereich von < 10-2 mbar * I / s * m2 und besonders bevorzugt im Bereich von < 10-3 mbar * I / s * m2 (gemessen nach ASTM F-1249-90). Vorzugsweise werden durch diese geringen Gasdurchgangsraten die vorgenannten geringen Anstiege der Wärmeleitfähigkeit erreicht.The area-specific gas permeation rate of the cover is preferably <10 -5 mbar*I/s*m 2 and particularly preferably <10 -6 mbar*I/s*m 2 (measured according to ASTM D-3985). This gas permeation rate applies to nitrogen and oxygen. For other types of gas (especially water vapour), there are also low gas permeation rates, preferably in the range of < 10 -2 mbar * I / s * m 2 and particularly preferably in the range of < 10 -3 mbar * I / s * m 2 (measured according to ASTM F -1249-90). Preferably, these low gas permeation rates achieve the aforementioned small increases in thermal conductivity.
Bei den oben genannten Werten handelt es sich um exemplarische, bevorzugte Angaben, die die Erfindung nicht beschränken.The values given above are exemplary, preferred details that do not restrict the invention.
Vorzugsweise ist außer der Vollwärmedämmung kein weiteres Dämmmaterial, wie z.B. PU-Schaum vorhanden.Apart from the full thermal insulation, there should preferably be no other insulating material, such as PU foam.
Das erfindungsgemäße Kühl- bzw. Gefriergerät ist mit einer derartigen Vollwärmedämmung ausgeführt, die vorzugsweise einen oder mehrere der vorgenannten Merkmale aufweist und die einen Bestandteil des Korpus bildet und ggf. zusätzlich im Verschlusselement angeordnet ist.The refrigerator or freezer according to the invention is designed with such a full thermal insulation, preferably one or more of the aforementioned Features and forms part of the body and is optionally also arranged in the closure element.
Eine vollflächige Vakuumdämmung hat weitreichende Folgen für die Funktion des Kühl- bzw. Gefriergerätes. Aufgrund des stark reduzierten Wärmeeinfalls in den gekühlten Innenraum wird die benötigte Kälteleistung reduziert und bedingt durch die dadurch niedrigeren Wärmeströme verändern sich die Anforderungen an die Wärmetauscher (Verdampfer, Verflüssiger) des Kältemittelkreislaufes.A full-surface vacuum insulation has far-reaching consequences for the function of the refrigerator or freezer. Due to the greatly reduced incidence of heat in the cooled interior, the required cooling capacity is reduced and due to the resulting lower heat flows, the requirements for the heat exchanger (evaporator, condenser) of the refrigerant circuit change.
Bei einer Vollvakuumdämmung gemäß der vorliegenden Erfindung ist zu beachten, dass Wärmebrücken in der Dämmung einen prozentual verstärkten Einfluss auf den Gesamtwärmeverlust bzw. -wärmeeintrag in den gekühlten Innenraum haben. Dabei stellen Durchführungen durch den Vakuumdämmraum eine erhöhte Komplexität dar und sind zum Erreichen eines ausreichenden Qualitätsniveaus in der Fertigung soweit wie möglich zu vermeiden.In the case of full-vacuum insulation according to the present invention, it should be noted that thermal bridges in the insulation have a proportionally increased influence on the total heat loss or heat input into the cooled interior. Feedthroughs through the vacuum insulation space represent increased complexity and should be avoided as far as possible in order to achieve a sufficient level of quality in production.
Erfindungsgemäß ist vorgesehen, dass der komplette Kältemittelkreislauf als Baugruppe ausgeführt ist, die in den Korpus eingesetzt ist. Darunter ist zu verstehen, dass die Baugruppe in geeigneter Weise auf den Korpus aufgesetzt ist. Der Begriff "in" bedeutet nicht, dass sich die gesamte Baugruppe innerhalb des Korpus, d.h. innerhalb des gekühlten Innenraums befindet.According to the invention it is provided that the complete refrigerant circuit is designed as an assembly that is inserted into the body. This means that the assembly is placed on the body in a suitable manner. The term "in" does not mean that the entire assembly is inside the body, i.e. inside the refrigerated interior.
Vorzugsweise ist die Baugruppe so mit dem Korpus verbunden, dass ein Teil der Komponenten des Kältemittelkreislaufes innerhalb des gekühlten Innenraums und ein Teil der Komponenten des Kältemittelkreislaufes außerhalb des gekühlten Innenraums angeordnet sind.The assembly is preferably connected to the body in such a way that some of the components of the refrigerant circuit are arranged inside the refrigerated interior space and some of the components of the refrigerant circuit are arranged outside of the refrigerated interior space.
Erfindungsgemäß ist vorgesehen, dass in dem Vollvakuumdämmkörper wenigstens eine und vorzugsweise genaue eine randseitige Ausnehmung angeordnet ist, durch die die Saugleitung von dem Verdampfer zu dem Kompressor des Kältemittelkreislaufes verläuft und die mit wenigstens einer Wärmedämmung, vorzugsweise mit wenigstens einer konventionellen Wärmedämmung versehen ist.According to the invention, at least one and preferably precisely one peripheral recess is arranged in the full-vacuum insulating body, through which the suction line runs from the evaporator to the compressor of the refrigerant circuit and which is provided with at least one thermal insulation, preferably with at least one conventional thermal insulation.
Durch beide Aspekte, die auch kombiniert vorliegen können, wird den geänderten Rahmenbedingungen aufgrund der Verwendung eines Vollvakuumsystems Rechnung getragen.Both aspects, which can also exist in combination, take into account the changed framework conditions due to the use of a full vacuum system.
Durch die Verwendung einer Baugruppe, die den kompletten Kältemittelkreislauf umfasst, d.h. Verdampfer, Saugleitung, Kompressor, Verflüssiger und eine Drossel bzw. Kapillare, wird erreicht, dass der Vollvakuumdämmkörper vergleichsweise einfach ausgeführt sein kann, da im Rahmen der Fertigung nur das Erfordernis besteht, dass die Baugruppe in geeigneter Weise in bzw. an den Korpus eingesetzt ist, ohne dass eine Vielzahl von Durchbrüchen in dem Vollvakuumdämmkörper erforderlich ist.The use of an assembly that includes the entire refrigerant circuit, i.e. evaporator, suction line, compressor, condenser and a throttle or capillary, means that the full-vacuum insulating body can be designed in a comparatively simple manner, since the only requirement during production is that the module is used in a suitable manner in or on the body without a large number of openings in the full-vacuum insulating body being required.
Erfindungsgemäß ist vorgesehen, dass der Vollvakuumdämmkörper wenigstens eine und vorzugsweise genau eine randseitige Ausnehmung bzw. Rücksprung aufweist, durch die zumindest die Saugleitung von dem Verdampfer zu dem Kompressor verläuft.According to the invention, it is provided that the full-vacuum insulating body has at least one, and preferably precisely one, edge-side recess or recess, through which at least the suction line runs from the evaporator to the compressor.
Vorzugsweise verläuft durch die genannte randseitige Ausnehmung auch die Kapillare, durch die das Kältemittel von dem Verflüssiger zu dem Verdampfer gelangt.The capillary, through which the refrigerant passes from the condenser to the evaporator, preferably also runs through the recess mentioned at the edge.
Die Kapillare kann innerhalb der Saugleitung verlaufen.The capillary can run inside the suction line.
In einer bevorzugten Ausgestaltung wird auf das vorgefertigte Vollvakuumgehäuse, d.h. auf den Korpus mit dem Vollvakuumdämmkörper, der komplette Kältemittelkreislauf nachträglich so eingeschoben, dass das Saugrohr im Rücksprung des Vollvakuumgehäuses liegt. Es kann sodann durch eine konventionelle Dämmung, wie bspw. eine Ausschäumung überdämmt werden.In a preferred embodiment, the complete refrigerant circuit is subsequently pushed onto the prefabricated full-vacuum housing, ie onto the body with the full-vacuum insulating body, in such a way that the suction tube lies in the recess of the full-vacuum housing. It can then be covered with conventional insulation, such as foam insulation.
Es kann des Weiteren wenigstens eine Tauwasserleitung vorhanden sein, mittels derer Wasser aus dem gekühlten Innenraum abgeführt wird, wobei auch diese Tauwasserableitung ebenfalls durch die genannte randseitige Ausnehmung, die im Folgenden auch als Rücksprung bezeichnet wird, verläuft.There can also be at least one condensate line, by means of which water is drained from the cooled interior, this condensate drain also running through the said edge-side recess, which is also referred to below as a recess.
In diesem Fall verläuft durch den Rücksprung somit nicht nur die Durchführung für den Tauwasserablauf sondern auch das Saugrohr.In this case, not only the passage for the condensation water drainage but also the suction pipe runs through the recess.
Auch der Tauwasserablauf ist vorzugsweise mit einer Wärmedämmung versehen, bzw. überdeckt, wobei es sich auch in diesem Fall vorzugsweise um eine konventionelle Wärmedämmung handelt.The condensate drain is also preferably provided with thermal insulation or covered, with conventional thermal insulation preferably also being involved in this case.
In einer weiteren Ausgestaltung der Erfindung ist vorgesehen, dass die Saugleitung zumindest abschnittsweise an der Außenseite des Vollvakuumdämmkörpers bzw. des Korpus entlang läuft und das wenigstens eine Wärmedämmung, vorzugsweise eine konventionelle Wärmedämmung, wie bspw. eine PU-Schaum, der Saugleitung über einen Teilabschnitt oder über die gesamte Länge der auf der Außenseite verlaufenden Saugleitung vorliegt.In a further embodiment of the invention, it is provided that the suction line runs at least in sections along the outside of the full-vacuum insulating body or the body and that at least one thermal insulation, preferably conventional thermal insulation such as PU foam, covers the suction line over a partial section or over the entire length of the suction line running on the outside.
Weiterhin kann vorgesehen sein, dass sich der Kältemittelkreislauf im Bodenbereich des Gerätes befindet. Dabei ist es denkbar, dass die Baugruppe so an den Bodenbereich des Gerätes angeordnet wird, dass sich der Verdampfer oberhalb des Bodens, d.h. in dem gekühlten Innenraum, und der Kompressor und der Verflüssiger unterhalb des Bodens, d.h. außerhalb des gekühlten Innenraums, befindet.Furthermore, it can be provided that the refrigerant circuit is located in the bottom area of the device. It is conceivable that the assembly is arranged on the floor area of the device in such a way that the evaporator is above the floor, i.e. in the cooled interior, and the compressor and the condenser are below the floor, i.e. outside the cooled interior.
In diesem Fall wird somit ein "Sockelaggregat" bereitgestellt, dass den Kompressor und den Verflüssiger aufweist und das darüber hinaus den innerhalb des gekühlten Innenraums angeordneten Verdampfer aufweist.In this case, a “pedestal unit” is thus provided which has the compressor and the condenser and which also has the evaporator arranged inside the cooled interior.
Die Baugruppe kann zudem zumindest einen Ventilator umfassen, der die durch den Verdampfer gekühlte Luft in den gekühlten Innenraum befördert bzw. darin zirkuliert.The assembly may also include at least one fan that conveys or circulates the air cooled by the evaporator into the cooled interior.
Grundsätzlich ist auch eine Anordnung der Baugruppe in einem anderen Abschnitt des Kühl- bzw. Gefriergerätes denkbar, wie bspw. auf der Rückseite des Korpus.In principle, an arrangement of the assembly in another section of the refrigerator or freezer is also conceivable, such as on the back of the body.
Die vorliegende Erfindung ist nicht auf schrankartige Kühl- und/oder Gefriergeräte beschränkt, sondern umfasst auch Kühl- bzw. Gefriertruhen.The present invention is not limited to cabinet-like refrigerators and/or freezers, but also includes refrigerators or chest freezers.
Der Vollvakuumdämmkörper kann bspw. eine einfache rechteckige Form vergleichbar mit einer Schuhschachtel aufweisen und keine oder nur kleinere Erhebungen oder Vertiefungen aufweisen.The full-vacuum insulating body can, for example, have a simple rectangular shape comparable to a shoe box and have no or only small elevations or depressions.
Bevorzugt ist es, wenn der Vollvakuumdämmkörper keinerlei Durchbrüche aufweist.It is preferred if the full-vacuum insulating body does not have any openings.
Vorzugsweise ist vorgesehen, dass der Vollvakuumdämmkörper nur einen einzigen Rücksprung aufweist, nämlich die eingangs genannte randseitige Öffnung, die einen Rücksprung zur Türebene bzw. zur Ebene des Verschlusselementes bildet. Wie oben ausgeführt, bildet dieser Rücksprung die Aufnahme vorzugsweise für die Leitungen der Kältetechnik, wobei diese Leitungen vorzugsweise lokal konventionell überdämmt sind.Provision is preferably made for the full-vacuum insulating body to have only a single recess, namely the edge-side opening mentioned at the outset, which forms a recess relative to the door level or to the level of the closure element. As stated above, this recess preferably forms the receptacle for the lines of the refrigeration technology, these lines preferably being insulated locally in a conventional manner.
Erfindungsgemäß ist vorgesehen, dass der Vollvakuumdämmkörper wenigstens eine Folie aufweist - wie eingangs ausgeführt - wobei die Folie als eingestülpter Klotzbodenbeutel ausgeführt ist.According to the invention, it is provided that the full-vacuum insulating body has at least one film--as stated at the outset--where the film is designed as an inverted block-bottom bag.
Erfindungsgemäß weist der Klotzbodenbeutel im Bereich des Rücksprungs Folienfalten auf, die den zur Ausbildung des Rücksprungs nötigen Folienüberschuss vorhalten.According to the invention, the block-bottom bag has foil folds in the area of the recess, which store the excess foil required to form the recess.
Die vorliegende Erfindung betrifft des Weiteren ein Verfahren zur Herstellung eines erfindungsgemäßen Kühl- bzw. Gefriergerätes, wobei ein Verfahrensschritt das Einsetzen des kompletten Kältemittelkreislaufes als Baugruppe in den Korpus umfasst. Dabei erfolgt das Einsetzen derart, dass zumindest die Saugleitung in den genannten Rücksprung, d.h. in der randseitigen Ausnehmung des Korpus bzw. des Vollvakuumdämmkörpers angeordnet ist.The present invention also relates to a method for producing a refrigerator or freezer according to the invention, a method step comprising the insertion of the complete refrigerant circuit as an assembly in the body. The insertion takes place in such a way that at least the suction line is arranged in the recess mentioned, i.e. in the edge-side recess of the body or the full-vacuum insulating body.
Wie oben ausgeführt kann die vorgefertigte Baugruppe zumindest einen Kompressor, Verflüssiger, Drossel bzw. Kapillare, Verdampfer einschließlich der Verbindungsleitungen und ggf. einen oder mehrere Ventilatoren aufweisen, die zur Erzeugung einer Luftströmung über den Verdampfer und/oder den Verflüssiger dienen.As stated above, the prefabricated assembly can have at least one compressor, condenser, throttle or capillary, evaporator including the connecting lines and possibly one or more fans that serve to generate an air flow over the evaporator and/or the condenser.
Denkbar ist es, dass der Kältemittelkreislauf beim Einsetzen in den Korpus bereits mit Kältemittel gefüllt ist.It is conceivable that the refrigerant circuit is already filled with refrigerant when it is inserted into the body.
Wie ausgeführt, wird das Saugrohr und ggf. weitere Rohrleitung des Kältemittelkreislaufes im Bereich des Rücksprungs und ggf. der daran angrenzenden Abschnitte vorzugsweise mit konventionell eingesetzten Dämmmaterialien, wie bspw. einer PU-Ausschäumung überdämmt, um den thermischen Weg durch die Metallrohre zu verlängern und den Wärmeverlust zu reduzieren.As stated, the suction pipe and possibly other pipelines of the refrigerant circuit in the area of the return and possibly the adjacent sections are preferably insulated with conventionally used insulating materials, such as PU foam, in order to lengthen the thermal path through the metal pipes and to reduce heat loss.
Vorzugsweise ist der Kältemittelkreislauf, der als Baugruppe ausgeführt ist des Weiteren mit allen Aktoren, wie bspw. Ventilen etc., ausgeführt, die zum Betrieb des Kältemittelkreislaufes benötigt werden. Entsprechendes gilt vorzugsweise auch für eine Steuerungs- oder Regelungseinheit zur Steuerung oder Regelung des Kältemittelkreislaufes.Preferably, the refrigerant circuit, which is designed as an assembly, is also designed with all actuators, such as valves, etc., that are required to operate the refrigerant circuit. The same preferably also applies to a control or regulation unit for controlling or regulating the refrigerant circuit.
