Gefrierschranktürbaugruppe  Freezer door assembly
Die Erfindung betrifft eine Gefrierschranktürbaugruppe nach dem Oberbegriff des Anspruchs 1. Ferner betrifft die Erfindung einen mit einer solchen Gefrierschranktürbaugruppe ausgerüsteten Gefrierschrank. The invention relates to a freezer door assembly according to the preamble of claim 1. Furthermore, the invention relates to a freezer equipped with such a freezer door assembly.
Eine derartige Gefrierschranktürbaugruppe ist durch offenkundige Vorbenutzung bekannt. Damit bei der bekannten Gefrierschranktürbaugruppe Marktforderungen nach der Beschlagfreiheit der Baugruppe nach dem öffnen und Wiederverschließen der Glastür und im Dauerbetrieb der Baugruppe erfüllt werden, muss die Baugruppe sehr aufwändig ausgeführt/ausgelegt werden, um das unerwünschte Kondensieren bzw. Resublimieren von Wasser bzw. Eis auf der Baugruppe/Baugruppenoberfläche zu verhindern. Dies führt z. B. dazu, dass der Energieaufwand zum Betreiben eines Gefrierschranks mit einer derartigen bekannten Gefrierschranktürbaugruppe hoch ist. Such a freezer door assembly is known from prior public use. In order for the known freezer door assembly to meet market demands for the assembly to be fog-free after opening and reclosing the glass door and in continuous operation of the assembly, the assembly must be designed / designed in a very complex manner in order to prevent the undesired condensation or resublimation of water or ice on the Prevent assembly / assembly surface. This leads e.g. B. that the energy required to operate a freezer with such a known freezer door assembly is high.
Eine weitere Gefrierschranktürbaugruppe ist bekannt aus der WO 2005/021886 A1. Another freezer door assembly is known from WO 2005/021886 A1.
Es ist eine Aufgabe der vorliegenden Erfindung, eine Gefrierschranktürbaugruppe der eingangs genannten Art derart weiterzubilden, dass keine Abstriche, was die Beschlagfreiheit angeht, gemacht werden müssen, wobei gleichzeitig ein im Vergleich zum Stand der Technik energieeffizienterer und zumindest in gleicher Weise optisch ansprechender Gefrierschrank resultieren soll. It is an object of the present invention to develop a freezer door assembly of the type mentioned at the outset in such a way that no compromises have to be made with regard to the freedom from fogging, which at the same time should result in a freezer which is more energy efficient and at least in the same way visually appealing in comparison with the prior art .
Diese Aufgabe ist erfindungsgemäß gelöst durch eine Gefrierschranktürbaugruppe mit den im Kennzeichnungsteil des Anspruchs 1 angegebenen Merkmalen. This object is achieved by a freezer door assembly with the features specified in the characterizing part of claim 1.
Ein Rahmenprofil mit einem Kunststoffprofilgrundkörper vermeidet im Bereich der seitlichen Scheibenverbundaufnahme eine unerwünschte Wärmebrücke zwischen dem Innenraum des Gefrierschranks und seiner Umgebung. Dies führt dazu, dass nicht die aufwändigen Maßnahmen wie beim Stand der Technik ergriffen werden müssen, um eine Beschlagfreiheit insbesondere des Rahmenprofils zu gewährleisten. Es ist insbesondere nicht erforderlich, das Rahmenprofil zu heizen. Gleichzeitig sorgt die Dekorschicht für ein optisch ansprechendes Äußeres des Rahmenprofils. Durch die guten Wärmeisolationseigenschaften des Rahmenprofils sind die Anforderungen an die Kühlleistung des Gefrierschranks verringert. Insgesamt resultiert daher eine höhere Energieeffizienz des Gefrierschranks. Unter einem Türpfosten wird erfindungsgemäß auch ein Teil eines Gefrierschrankkorpus verstanden, an dem die Glastür in ihrer Schließstellung anliegt. A frame profile with a plastic profile base body avoids an undesirable thermal bridge between the interior of the freezer and its surroundings in the area of the side pane composite receptacle. This means that the complex measures as in the prior art do not have to be taken in order to ensure that there is no fogging, particularly in the frame profile. In particular, it is not necessary to heat the frame profile. At the same time, the decorative layer ensures a visually appealing exterior of the frame profile. The good thermal insulation properties of the frame profile reduce the requirements for the cooling performance of the freezer. Overall, this results in a higher energy efficiency of the freezer. According to the invention, a door jamb is also understood to mean part of a freezer body against which the glass door rests in its closed position.
PVC als Material für den Kunststoffprofilgrundkörper nach Anspruch 2 hat sich wegen seiner Materialeigenschaften zum Aufbau eines Gefrierschranks als vorteilhaft herausgestellt. Je nach gewünschter Kombination von Materialeigenschaften bieten auch die anderen Materialien der im Anspruch 2 enthaltenen Materialienliste individuelle Vorteile. Geschäumte Thermoplaste können z. B. in einem Dichtbereiche zwischen 0,2 und 1 ,4 kg/l eingesetzt werden. Bevorzugt wird insbesondere eine Dichte im Bereich von 0,65 kg/l. PVC as a material for the plastic profile base body according to claim 2 has proven to be advantageous because of its material properties for building a freezer. Depending on the desired combination of material properties, the other materials of the material list contained in claim 2 also offer individual advantages. Foamed thermoplastics can e.g. B. in a sealing range between 0.2 and 1.4 kg / l. A density in the range of 0.65 kg / l is particularly preferred.
Eine Dekormetallfolie nach Anspruch 3 und 4 ist nicht nur optisch ansprechend, sondern führt auf Grund ihrer guten wärmeleitenden Eigenschaften auch zu einem gewissen thermischen Ausgleich auf der Sichtseite des Rahmenprofils. A decorative metal foil according to claims 3 and 4 is not only visually appealing, but also leads to a certain thermal compensation on the visible side of the frame profile due to its good heat-conducting properties.
Eine Dichtung nach Anspruch 5 führt zur Möglichkeit, den Türpfosten in seinem dem Innenraum des Gefrierschranks zugewandten bzw. diesem Innenraum benachbarten Abschnitt aus Kunststoff auszuführen, da ein zum Sichern der Glastür in der Schließstellung notwendiger magnetischer Abschnitt zusammen mit der Dichtung nach außen versetzt angeordnet werden kann. Dies verbessert die Isolationseigenschaften des Türpfostens, da eine unerwünschte Wärmebrücke im Bereich des metallischen Abschnitts des Türpfostens zumindest weitgehend vermieden werden kann. Das Profilelement verhindert im Bereich des Zwischenraums eine unerwünschte Konvektion im Inneren des Gefrierschranks. Das Profilelement bildet im Sinne dieses Anspruchs auch dann eine Trennung zwischen der Dichtung und dem Innenraum, wenn das Profilelement in der Schließstellung der Glastür nicht gleichzeitig am Türpfosten und am Rahmenprofil bzw. am Scheibenverbund anliegt. In der Schließstellung können vielmehr durchaus Freiräume bleiben, die jedoch wesentlich enger sind als der Zwischenraum, wodurch sich die gewünschte Konvektionsverhinderung durch, das Profilelement ergibt. A seal according to claim 5 leads to the possibility of executing the door jamb in its section of plastic facing the interior of the freezer or adjacent to this interior, since a magnetic section necessary for securing the glass door in the closed position can be arranged offset together with the seal to the outside . This improves the insulation properties of the door jamb, since an undesirable thermal bridge in the area of the metallic section of the door jamb can be at least largely avoided. The profile element prevents unwanted convection in the interior of the freezer in the area of the space. Within the meaning of this claim, the profile element also forms a separation between the seal and the interior when the profile element does not abut the door jamb and the frame profile or the pane assembly in the closed position of the glass door. Rather, in the closed position there can be clearances, which are, however, much narrower than the space in between, which results in the desired convection prevention by the profile element.
Ein Kunststoff profil nach Anspruch 6 hat eine zusätzliche Wärmeisolationswirkung. Ein Profilelement nach Anspruch 7 führt zu keinem erhöhten Montageaufwand für die Gefrierschranktürbaugruppe. A plastic profile according to claim 6 has an additional heat insulation effect. A profile element according to claim 7 leads to no increased assembly effort for the freezer door assembly.
Durch eine Wärmeleitmetallfolie nach Anspruch 8 wird vermieden, dass im Glasaufnahmebereich und in Hohlkammern des Rahmenprofils Kondenswasser entsteht oder sich niederschlägt. Ein inneres Beschlagen des Scheibenverbundes ist damit vermieden. Die Wärmeleitmetallfolie und die Dekormetallfolie umgreifen drei Seiten des Kunststoffprofilgrundkörpers, so dass eine Verzugsgefahr von diesem auf Grund der Temperaturwechsel, denen das Rahmenprofil ausgesetzt ist, reduziert ist. A heat-conducting metal foil according to claim 8 prevents condensation water from forming or precipitating in the glass receiving area and in hollow chambers of the frame profile. Internal fogging of the pane assembly is thus avoided. The heat-conducting metal foil and the decorative metal foil encompass three sides of the plastic profile base body, so that the risk of warping due to the temperature changes to which the frame profile is exposed is reduced.
Eine Wärmeleitfolie nach Anspruch 9 hat eine gute Wärmeleitfähigkeit. A heat-conducting film according to claim 9 has good thermal conductivity.
Folienstärken nach Anspruch 10 haben sich für den Einsatzzweck der Dekormetallfolie bzw. der Wärmeleitmetallfolie als ausreichend herausgestellt. Foil thicknesses according to claim 10 have been found to be sufficient for the intended use of the decorative metal foil or the heat-conducting metal foil.
Materialien für den Kunststoffprofilgrundkörper nach Anspruch 11 lassen sich durch eine entsprechende Auswahl der Materialkombination Thermoplaste/Füllstoff an die jeweiligen technischen Anforderungen/Auslegungen, insbesondere was die Wärmeleiteigenschaften angeht, gut anpassen. Materials for the plastic profile base body according to claim 11 can be adapted to the respective technical requirements / designs, in particular as far as the thermal conductivity properties are concerned, by appropriate selection of the material combination thermoplastics / filler.
Eine Dekorschicht nach Anspruch 12 kann Unregelmäßigkeiten der Oberflächenqualität der Sichtseiten des Kunststoffprofilgrundkörpers vorteilhaft abdecken. Dies gilt insbesondere dann, wenn als Material für den Kunststoffprofilgrundkörper ein geschäumter Thermoplast eingesetzt wird. Alternativ kann auch eine unbedampfte duroplastische oder thermoplastische Dekorfolie verwendet werden. Als weitere Variante ist es auch möglich, die Sichtseiten des Kunststoff profilgrundkörpers mit einem Dekorlack zu versehen. A decorative layer according to claim 12 can advantageously cover irregularities in the surface quality of the visible sides of the plastic profile body. This applies in particular if a foamed thermoplastic is used as the material for the plastic profile base body. Alternatively, a non-evaporated thermosetting or thermoplastic decorative film can also be used. As a further variant, it is also possible to provide the visible sides of the plastic profile base body with a decorative lacquer.
Trägermaterialien nach Anspruch 13 und Beschichtungen nach Anspruch 14 sowie Anspruch 15 haben sich für derartige Dekorschichten in Form von bedampften Folien als besonders geeignete Materialkombinationen herausgestellt. Backing materials according to claim 13 and coatings according to claim 14 and claim 15 have been found to be particularly suitable material combinations for such decorative layers in the form of vapor-deposited films.
Ein Haftvermittler, beziehungsweise ein Klebstoff gemäß den im Anspruch 16 angegebenen Varianten, stellt eine Verbindungsschicht dar, die sich zur sicheren Verbindung der Metallfolie am Kunststoffprofilgrundkörper als geeignet/vorteilhaft erwiesen hat. Eine weitere Aufgabe der Erfindung ist die Bereitstellung eines optisch ansprechenden und energieeffizienten Gefrierschranks mit einer möglichst beschlagfreien Glastür. An adhesion promoter, or an adhesive according to the variants specified in claim 16, represents a connection layer which has proven to be suitable / advantageous for the secure connection of the metal foil to the plastic profile base body. Another object of the invention is to provide an optically appealing and energy-efficient freezer with a glass door that is as fog-free as possible.
Diese Aufgabe ist erfindungsgemäß gelöst durch einen Gefrierschrank mit den im Anspruch 17 angegebenen Merkmalen. This object is achieved according to the invention by a freezer with the features specified in claim 17.
Die Vorteile des Gefrierschranks entsprechen denen, die vorstehend unter Bezugnahme auf die Gefrierschranktürbaugruppe erläutert wurden. The advantages of the freezer are the same as those discussed above with reference to the freezer door assembly.
Die Dekorschicht kann auf dem Kunststoffprofilgrundkörper, falls eine Dekorfolie eingesetzt wird, z. B. im Heißprägeverfahren aufgebracht werden. The decorative layer can on the plastic profile body, if a decorative film is used, for. B. be applied by hot stamping.
Die Dekorschicht kann auch durch ein Koextrusionsverfahren auf den Kunststoffprofilgrundkörper aufgebracht werden. Bei einer bevorzugten Variante wird die Dekorschicht als Dekorband unmittelbar dann auf dem Kunststoffprofilgrundkörper aufgebracht, wenn dieser nach erfolgter Extrusion auf eine bestimmte Temperatur abgekühlt ist. Hierbei wird zwischen dem Dekorband und dem Kunststoffprofilgrundkörper noch zusätzlich ein Haftvermittler eingebracht, z. B. indem das Dekorband mit dem Haftvermittler beschichtet wird. Die Dekorschicht kann auf dem Kunststoffprofilgrundkörper auch aufkaschiert werden, wobei hierzu, gegebenenfalls zusätzlich zum Haftvermittler, ein Kleber verwendet wird. Die Dekorschicht kann auch im Aufprägeverfahren aufgeprägt werden, wobei zwischen der Dekorschicht und dem Kunststoffprofilgrundkörper noch ein Haftvermittler eingebracht wird. Insgesamt ist die Verbindung möglich durch Verwendung von Klebern bzw. Haftgrundie- rungen für einen einzusetzenden Haftvermittler, wobei diese Adhäsionsmaterialien an die jeweilige Materialpaarung für die Dekorschicht einerseits und den Kunststoffprofilgrundkörper andererseits angepasst sind. The decorative layer can also be applied to the plastic profile base body by a coextrusion process. In a preferred variant, the decorative layer is applied as a decorative tape to the plastic profile base body when it has cooled to a certain temperature after the extrusion has taken place. Here, an adhesion promoter is additionally introduced between the decorative tape and the plastic profile base body, e.g. B. by coating the decorative tape with the coupling agent. The decorative layer can also be laminated onto the plastic profile base body, an adhesive being used for this purpose, optionally in addition to the adhesion promoter. The decorative layer can also be embossed using the stamping method, an adhesion promoter being introduced between the decorative layer and the plastic profile base body. Overall, the connection is possible by using adhesives or adhesive primers for an adhesive agent to be used, these adhesive materials being adapted to the respective material pairing for the decorative layer on the one hand and the plastic profile base body on the other hand.
Ein Ausführungsbeispiel der Erfindung wird nachfolgend an Hand der Zeichnung näher erläutert. Die einzige Figur 1 zeigt einen Horizontalschnitt durch einen Ausschnitt einer Gefrierschranktürbaugruppe. An embodiment of the invention is explained below with reference to the drawing. The only FIG. 1 shows a horizontal section through a section of a freezer door assembly.
Die Gefrierschranktürbaugruppe 1 ist Bestandteil eines ansonsten nicht weiter dargestellten Gefrierschranks. Die Gefrierschranktürbaugruppe 1 hat eine insgesamt mit 2 bezeichnete Glastür. Diese liegt in Schließstellung über eine flexible Dichtung 3 an einem Türpfosten 4 an. Die Glastür 2 umfasst als Mehrscheibenisolierglas einen Scheibenverbund 5 mit einer Mehrzahl, im dargestellten Ausführungsbeispiel mit drei, von voneinander mit Hilfe von Abstandselementen 6 beabstandeten Glasscheiben, nämlich einer einem Innenraum 7 des Gefrierschranks zugewandten Innenscheibe 8, einer Mittelscheibe 9 und einer Außenscheibe 10. Die Mittelscheibe 9 liegt zwischen der Innenscheibe 8 und der Außenscheibe 10. The freezer door assembly 1 is part of an otherwise not shown freezer. The freezer door assembly 1 has a glass door labeled 2 overall. In the closed position, this rests on a door post 4 via a flexible seal 3. As a multi-pane insulating glass, the glass door 2 comprises a pane assembly 5 with a plurality, in the exemplary embodiment shown, of three panes of glass spaced apart from one another with the aid of spacing elements 6, namely an inner pane 8 facing an interior 7 of the freezer, a central pane 9 and an outer pane 10. The central pane 9 lies between the inner pane 8 and the outer pane 10.
Der Scheibenverbund 5 ist an seinem - in der Schließstellung dem Türpfosten 4 benachbarten - vertikalen Randabschnitt 11 von einem ebenfalls vertikal verlaufenden Rahmenprofil 12 aufgenommen. Im Bereich dieser Aufnahme ist das Rahmenprofil 12 als im Wesentlichen U-förmige Aufnahmenut 13 für den Scheibenverbund 5 ausgebildet. Die Abstandselemente 6 sind mit den Scheiben 8 bis 10 über Schichten eines Primärdichtstoffes 13a aus Butyl-Kautschuk, also über Kleberschichten, verbunden. Zwischen einem Grund 14 der Aufnahmenut 13 und den Abstandelementen 6 sind als Sekundärdichtstoffe Dichtelemente 15 aus Kunststoff, insbesondere aus Polyurethan, angeordnet, die den von den Scheiben 8 und 9 bzw. 9 und 10 des Scheibenverbundes 5 erzeugten Innenraum gegen die Umgebung abdichten. The pane assembly 5 is received on its vertical edge section 11, which is adjacent to the door jamb 4 in the closed position, by a frame profile 12 which also runs vertically. In the area of this receptacle, the frame profile 12 is designed as an essentially U-shaped receptacle 13 for the pane assembly 5. The spacer elements 6 are connected to the disks 8 to 10 via layers of a primary sealant 13a made of butyl rubber, that is to say via adhesive layers. Between a base 14 of the receiving groove 13 and the spacing elements 6, sealing elements 15 made of plastic, in particular polyurethane, are arranged as secondary sealants, which seal the interior space produced by the panes 8 and 9 or 9 and 10 of the pane composite 5 against the environment.
Zwischen den Dichtelementen 15 und dem Rahmenprofil 12 ist auf den Grund 14 eine Wärmeleitmetallfolie 16 über einen Haftvermittler angeklebt/aufgebracht. Diese erstreckt sich in der Aufnahmenut 13 zwischen der Innenscheibe 8 und der Außenscheibe 10. Die Wärmeleitmetallfolie 16 ist aus Aluminium und hat eine Dicke von 0,1 mm. Auch andere Foliendicken zwischen 0,01 und 2 mm sind möglich. Die Wärmeleitmetallfolie 16 kann auch aus einem anderen, gut wärmeleitenden Material bestehen. Prinzipiell ist auch denkbar, an Stelle einer Metallfolie eine nichtmetallische, wärmeleitende Folie oder Beschichtung einzusetzen. Denkbar in diesem Erfindungszusammenhang sind auch Dekorfolien, bestehend aus einer Beschichtung einer Titannitridverbindung oder einer Bornitridverbindung oder einer Aluminiumnitridverbindung oder einer Siliziumnitrid- oder Siliziumoxinitridverbindung oder einer Siliziumoxidverbindung oder einer Aluminium-Silizium-Titanverbindungen oder einer Verbindung aus Tantalsiliziden oder undotiertes oder dotiertes Polysilizium und/oder amorphes Silizium oder einer Titan-Wolfram-Verbindung oder Titansiliziden oder einer Titanoxinitridverbindung oder einer Wolframsilizidverbindung oder Molybdänsilizidverbin- dung, aufgebracht in Dünnschichttechnik wie beispielsweise Plasmaabscheidung (PE-CVD- Verfahren) oder Sputterverfahren auf einem Folienträgermaterial mit Haftvermittler- /Kleberschicht. Das Rahmenprofil 12 ist als Hohlkammerprofil ausgebildet. Es hat einen Kunststoffprofilgrundkörper 17, im dargestellten Ausführungsbeispiel aus Polyvinylchlorid (PVC). Der Kunststoffprofilgrundkörper 17 ist an seinen Sichtseiten, in der Figur 1 also an der unteren und an der linken Seite, mit einer Dekorschicht in Form einer Dekormetallfolie 18 beschichtet. Letztere besteht beispielsweise aus Aluminium und hat eine Dicke von 0,1 mm. Je nach Dekoranforderungen kann die Dekormetallfolie/Dekorfolie 18 auch aus anderen Metallen bestehen. Die Dekormetallfolie/Dekorfolie 18 kann auch eine andere Dicke zwischen 0,01 und 2 mm haben. Between the sealing elements 15 and the frame profile 12, a heat-conducting metal foil 16 is glued / applied to the base 14 via an adhesion promoter. This extends in the receiving groove 13 between the inner pane 8 and the outer pane 10. The heat-conducting metal foil 16 is made of aluminum and has a thickness of 0.1 mm. Other film thicknesses between 0.01 and 2 mm are also possible. The heat-conducting metal foil 16 can also consist of another, good heat-conducting material. In principle, it is also conceivable to use a non-metallic, heat-conducting film or coating instead of a metal film. Also conceivable in this context of the invention are decorative films consisting of a coating of a titanium nitride compound or a boron nitride compound or an aluminum nitride compound or a silicon nitride or silicon oxynitride compound or a silicon oxide compound or an aluminum-silicon-titanium compound or a compound made of tantalum silicides or undoped or doped polysilicon and / or amorphous Silicon or a titanium-tungsten compound or titanium silicide or a titanium oxynitride compound or a tungsten silicide compound or molybdenum silicide compound, applied using thin-film technology such as plasma deposition (PE-CVD process) or sputtering process on a film carrier material with a bonding agent / adhesive layer. The frame profile 12 is designed as a hollow chamber profile. It has a plastic profile base body 17, in the illustrated embodiment made of polyvinyl chloride (PVC). The plastic profile base body 17 is coated on its visible sides, ie in FIG. 1 on the lower and on the left side, with a decorative layer in the form of a decorative metal foil 18. The latter is made of aluminum, for example, and has a thickness of 0.1 mm. Depending on the decorative requirements, the decorative metal foil / decorative foil 18 can also consist of other metals. The decorative metal foil / decorative foil 18 can also have a different thickness between 0.01 and 2 mm.
Der Kunststoffprofilgrundkörper 17 ist (siehe Figur 1) oben abgedeckt von einer Deckplatte 18a, die in eine obere Rastaufnahme des Kunststoffprofilgrundkörpers 17 eingerastet ist. The plastic profile base body 17 (see FIG. 1) is covered at the top by a cover plate 18a, which is snapped into an upper catch receptacle of the plastic profile base body 17.
Zwischen einer in der Figur 1 oberen Wand 19 der Deckplatte 18a und einer dieser oberen Wand 19 zugewandten unteren Wand 20 des Türpfostens 4 ist die flexible Dichtung 3 angeordnet. Letztere hat einen zum Beispiel aus der WO 2005/021886 A1 bekannten Aufbau mit drei elastischen Dichtwänden, nämlich einer dem Innenraum 7 zugewandten Innenwand 21 , einer Mittelwand 22 und einer Außenwand 23. Die Dichtwände 21 bis 23 sind Bestandteile eines einstückigen Dichtprofils 24 aus gegenüber dem Material des Rahmenprofils 12 weicheren Kunststoff, zum Beispiel aus weichem PVC. In bekannter Weise weist das Dichtprofil 24 einen Rastprofilabschnitt 24a auf, welcher in eine Aufnahmekammer 24b der Deckplatte 18a eingerastet ist. In der Figur 1 oberhalb der Mittelwand 22 und der Außenwand 23 weist das Dichtprofil 24 eine Aufnahmekammer 25 für einen Magneten 26 auf. Letzterer wirkt in der Schließstellung der Glastür mit einem metallischen Abschnitt 27 der unteren Wand 20 des Türpfostens 4 zusammen. The flexible seal 3 is arranged between an upper wall 19 of the cover plate 18a in FIG. 1 and a lower wall 20 of the door jamb 4 facing this upper wall 19. The latter has, for example, a structure known from WO 2005/021886 A1 with three elastic sealing walls, namely an inner wall 21 facing the interior 7, a middle wall 22 and an outer wall 23. The sealing walls 21 to 23 are components of a one-piece sealing profile 24 from the Material of the frame profile 12 softer plastic, for example made of soft PVC. In a known manner, the sealing profile 24 has a locking profile section 24a, which is snapped into a receiving chamber 24b of the cover plate 18a. In FIG. 1 above the middle wall 22 and the outer wall 23, the sealing profile 24 has a receiving chamber 25 for a magnet 26. The latter cooperates with a metallic section 27 of the lower wall 20 of the door jamb 4 in the closed position of the glass door.
Die Dichtung 3 ist vom Innenraum 7 her gesehen soweit nach außen versetzt, dass benachbart zur Dichtung 3 zwischen dem Türpfosten 4 und dem Randabschnitt 11 des Scheibenverbundes 5 ein Zwischenraum 28 gebildet ist. Dieser ist teilweise von einem Profilelement 29 ausgefüllt. Letzteres stellt eine Trennung zwischen der Dichtung 3 und dem Innenraum 7 dar. Das Profilelement 29 ist als Hohlkammerprofil ausgebildet. In der Schließstellung der Glastür 2 verbleibt zwischen dem Profilelement 29 und dem Türpfosten 4 ein Kanal 30 definierter Weite, so dass sichergestellt ist, dass in der Schließstellung das Profilelement 29 nicht gleichzeitig an der Glastür 2 und am Türpfosten 4 anliegt und auf diese Weise die Schließstellung unerwünscht beeinflusst. Das Profilelement 29 ist einstückig mit der Deckplatte 18a ausgebildet. Durch den dargestellten Aufbau der Gefrierschranktürbaugruppe 1 wird eine Temperaturverteilung in der Gefrierschranktürbaugruppe 1 erreicht, die verhindert, dass das Rahmenprofil 12 an seiner Sichtseite im Betrieb unerwünscht beschlägt. Dies wird durch eine Kombination folgender Maßnahmen erreicht: Seen from the interior 7, the seal 3 is offset so far that an intermediate space 28 is formed adjacent to the seal 3 between the door jamb 4 and the edge section 11 of the pane assembly 5. This is partially filled by a profile element 29. The latter represents a separation between the seal 3 and the interior 7. The profile element 29 is designed as a hollow chamber profile. In the closed position of the glass door 2, a channel 30 of defined width remains between the profile element 29 and the door jamb 4, so that it is ensured that in the closed position the profile element 29 does not abut the glass door 2 and the door jamb 4 at the same time, and in this way the closed position undesirably affected. The profile element 29 is formed in one piece with the cover plate 18a. Due to the construction of the freezer door assembly 1 shown, a temperature distribution in the freezer door assembly 1 is achieved which prevents the frame profile 12 from misting up on its visible side during operation. This is achieved by a combination of the following measures:
Zunächst verhindert die Ausgestaltung des Profilgrundkörpers 17 aus Kunststoff die Ausbildung einer Wärmebrücke zwischen dem Innenraum 7 und der Umgebung des Gefrier- schranks. Hierdurch wird erreicht, dass die Temperatur des Rahmenprofils 12 im Bereich der Sichtseiten ausreichend hoch ist, so dass ein Beschlagen dieser Sichtseiten verhindert ist. Dadurch, dass die Dichtung 3 nach außen versetzt angeordnet ist, reicht es aus, den metallischen Abschnitt 27 nur bis knapp über die Mitte des Türpfostens 4 zu ziehen. Eine restliche Wand 31 des Türpfostens 4, also der Abschnitt, der dem Innenraum 7 zugewandt bzw. benachbart ist, wird durch einen U-förmigen Profilabschnitt aus Kunststoff, zum Beispiel aus PVC, gebildet. Hierdurch und durch eine innere Füllung des Türpfostens 4 aus ebenfalls schlecht wärmeleitendem Material, im dargestellten Beispiel aus PUR-Schaum, wird es ermöglicht, dass die Außenseite des Türpfostens 4 nicht zu kalt wird und daher ebenfalls nicht beschlägt. Unerwünschte Konvektion im Bereich des Zwischenraums 28 wird durch das Profilelement 29 wirksam verhindert. Hierdurch wird insbesondere eine zu starke Abkühlung der Dichtung 3 vermieden. Auf Grund der wärmeleitenden Eigenschaft der Wärmeleitmetallfolie 16 wird von der Außenseite der Glastür 2 her genügend Wärme in den Randabschnitt 11 und in den Grund 14 der Aufnahmenut 13 eingetragen, so dass Kon- denswasserbildung in diesem Bereich auf Grund einer zu starken Abkühlung vorteilhaft verhindert wird. Insbesondere wird ein inneres Beschlagen des Scheibenverbundes 5 effektiv vermieden. Die Wärmeleitmetallfolie 16 stellt somit also eine wärmeleitende Verbindung zwischen der Innen- und der Außenseite des Scheibenverbundes 5 her. First, the design of the profile base body 17 made of plastic prevents the formation of a thermal bridge between the interior 7 and the surroundings of the freezer. This ensures that the temperature of the frame profile 12 is sufficiently high in the region of the visible sides so that fogging of these visible sides is prevented. Due to the fact that the seal 3 is arranged offset to the outside, it is sufficient to pull the metallic section 27 only just above the middle of the door jamb 4. A remaining wall 31 of the door jamb 4, that is to say the section which faces or is adjacent to the interior space 7, is formed by a U-shaped profile section made of plastic, for example made of PVC. This and an inner filling of the door jamb 4 made of a material that is also poorly heat-conducting, in the example shown made of PUR foam, makes it possible for the outside of the door jamb 4 not to become too cold and therefore also not fog up. Unwanted convection in the area of the space 28 is effectively prevented by the profile element 29. In this way, excessive cooling of the seal 3 is avoided in particular. On account of the heat-conducting property of the heat-conducting metal foil 16, sufficient heat is introduced from the outside of the glass door 2 into the edge section 11 and into the bottom 14 of the receiving groove 13, so that condensation water formation in this area is advantageously prevented due to excessive cooling. In particular, fogging of the pane assembly 5 is effectively avoided. The heat-conducting metal foil 16 thus creates a heat-conducting connection between the inside and the outside of the pane assembly 5.
Die Dekormetallfolie/Dekorfolie 18 stellt eine ansprechende Optik des Rahmenprofils 12 sicher. Gleichzeitig sorgt die Dekormetallfolie/Dekorfolie 18 gemeinsam mit der Wärmeleitmetallfolie 16 dafür, dass der Kunststoffprofilgrundkörper 17 von drei Seiten mit Metallfolie umgeben ist. Dies reduziert die Gefahr eines Verzuges des Kunststoffprofilgrundkörpers 17 des Rahmenprofils 12. The decorative metal foil / decorative foil 18 ensures an attractive appearance of the frame profile 12. At the same time, the decorative metal foil / decorative foil 18 together with the heat-conducting metal foil 16 ensures that the plastic profile base body 17 is surrounded on three sides with metal foil. This reduces the risk of the plastic profile base body 17 of the frame profile 12 being distorted.
