Description

Die vorliegende Erfindung betrifft ein Kühl- und/oder Gefriergerät mit einer Glastüre, die einen Metallrahmen aufweist, in den eine Verglasung eingesetzt ist. Kühlgeräte im Sinne der vorliegenden Anmeldung können auch Klimaschränke zur Aufbewahrung insbesondere von Wein sein.The present invention relates to a refrigerator and / or freezer with a glass door, which has a metal frame into which a glazing is inserted. Refrigerators in the context of the present application can also be climatic cabinets for storing wine in particular.

Die Schrift US 6,655,760 zeigt ein Kühlgerät gemäß dem Oberbegriff des Anspruchs 1. Weiterhin zeigt die DE 37 16 914 einen Klimaprüfschrank, dessen Tür eine Außenverkleidung und eine Innenblende umfasst, zwischen denen eine Isolierschicht angeordnet ist. Ferner zeigt die EP 0 953 807 eine Sichttür für ein Hausgerät, bei der eine gebogene Frontscheibe mittels Adapters an einem ebenen Rahmen befestigt ist.The font US 6,655,760 shows a cooling device according to the preamble of claim 1. Furthermore, the DE 37 16 914 a climate test cabinet whose door comprises an outer lining and an inner panel, between which an insulating layer is arranged. Furthermore, the shows EP 0 953 807 a glazed door for a household appliance, in which a curved front window is attached by means of adapter to a flat frame.

Bisherige Glastüren von Kühlgeräten sind in mehrerer Hinsicht nachteilig. Soweit ihr Metallrahmen aus Aluminiumstrangpressprofilen besteht, die auf Gehrung geschnitten und zusammengesetzt sind, sind an den Verbindungsstellen durch Toleranzen Spalte unvermeidbar. Zusätzliche Applikationen wie Schlösser, Sichtfenster und dergleichen sind nur schwer in die Strangpressprofile einbringbar. Zudem ist die Kontur des Metallrahmens durch die Rahmenprofile mehr oder minder vorgegeben und allenfalls durch zusätzliche Bearbeitung geringfügig anpassbar.Previous glass doors of refrigerators are disadvantageous in several respects. As far as their metal frame is made of extruded aluminum sections that are mitered and assembled, gaps at the joints are inevitable due to tolerances. Additional applications such as locks, windows and the like are difficult to introduce into the extruded profiles. In addition, the contour of the metal frame is more or less predetermined by the frame profiles and possibly slightly adaptable by additional processing.

Soweit der Rahmen von Glastüren aus Kunststoffextrusionsprofilen und/oder -spritzteilen durch Verschweißen oder Zusammenstecken aufgebaut wird, ist regelmäßig keine hochwertige Optik erreichbar. Durch das Verschweißen kommt es zu sichtbaren Stoßstellen. Zudem kann durch die Kombination verschiedener Kunststoffteile meist keine einheitliche Farbe oder Oberfläche erreicht werden.As far as the frame of glass doors made of plastic extrusion profiles and / or injection-molded parts is built by welding or plugging, no high-quality optics is regularly achievable. Welding leads to visible joints. In addition, the combination of different plastic parts usually no uniform color or surface can be achieved.

Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, ein verbessertes Kühl- und/oder Gefriergerät der genannten Art zu schaffen, das Nachteile des Standes der Technik vermeidet und letzteren in vorteilhafter Weise weiterbildet. Insbesondere soll eine optisch hochwertige Glastüre mit ausreichender Stabilität geschaffen werden.The present invention is therefore an object of the invention to provide an improved refrigerator and / or freezer of the type mentioned, which avoids the disadvantages of the prior art and the latter further develops in an advantageous manner. In particular, an optically high-quality glass door with sufficient stability is to be created.

Diese Aufgabe wird erfindungsgemäß durch ein Kühl- und/oder Gefriergerät gemäß Anspruch 1 gelöst. Bevorzugte Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.This object is achieved by a refrigerator and / or freezer according to claim 1. Preferred embodiments of the invention are the subject of the dependent claims.

Erfindungsgemäß ist also der die Verglasung umgebende Metallrahmen nicht aus mehreren Stücken zusammengesetzt. Er besteht aus einem umlaufend integral einstückig ausgebildeten Metallmantel, der zumindest auf der Sichtseite der Tür nahtfrei ausgebildet ist. Hierdurch wird eine bislang nicht erreichte homogene Optik verwirklicht. Farbliche Abweichungen, sichtbare Spaltbildung oder Stoßstellen sind beseitigt. Die Außenhülle der Tür besteht aus einem vollflächig gleichmäßig ausgebildeten und ausgerichteten Material. Um dennoch die notwendige Stabilität zu erreichen, ist der Metallmantel umlaufend mit einem Schaumkörper hinterschäumt bzw. ausgeschäumt. Hierdurch kann der integral einstückige Metallmantel ungeachtet der üblichen Stabilitätsanforderungen an den Metallrahmen in seiner Formgebung wesentlich variantenreicher und nahezu beliebig gestaltet werden.According to the invention, therefore, the metal frame surrounding the glazing is not composed of several pieces. It consists of a circumferentially integrally formed integrally metal shell, which is formed seamless at least on the visible side of the door. As a result, a hitherto unreached homogeneous optics is realized. Color deviations, visible gaps or joints are eliminated. The outer shell of the door consists of a full-surface evenly trained and aligned material. In order nevertheless to achieve the necessary stability, the metal shell is circumferentially foam-backed or foamed with a foam body. As a result, the integral one-piece metal shell regardless of the usual stability requirements for the metal frame in its shape significantly more varied and almost arbitrarily designed.

Insbesondere besteht der integral einstückige Metallmantel aus einem spanfrei umgeformten Blechprofil, das aus einer einstückigen Blechplatine gefertigt sein und für die Verglasung eine zentrale Ausstanzung aufweisen kann. Vorzugsweise ist der Metallmantel tiefgezogen. Alternativ oder zusätzlich kann er gebogen und gebördelt sein. Ungebogene bzw. -gebördelte Randstege können an Stoßstellen im unsichtbaren Bereich verschweißt sein.In particular, the integrally one-piece metal shell consists of a chip-free deformed sheet metal profile, which can be made of a one-piece sheet metal blank and can have a central punched-out for the glazing. Preferably, the metal shell is deep-drawn. Alternatively or additionally, it may be bent and beaded. Unbended or -branched edge webs can be welded at joints in the invisible area.

Die Innenseite des Metallmantels ist flächig, vorzugsweise vollflächig, mit dem Schaumkörper verbunden. Insbesondere wenn der Metallmantel im Querschnitt zueinander geneigte Flanken besitzt, kann durch das Hinterschäumen eine beträchtliche Aussteifung erreicht werden. Die Maßhaltigkeit des Metallmantels verbessert sich durch das Schäumen beträchtlich. Zugleich verbessert das Hinterschäumen des Metallmantels beträchtlich den Wärmedurchgangskoeffizienten, den sogenannten "K-Wert" des Profils. Darüber hinaus wird durch den Schaumkörper eine deutliche Reduktion der Kondensatbildung am Rahmen und im Übergang zur Verglasung erzielt. Der Metallrahmen kann auch ohne eine Heizung weitgehend kondensatfrei gehalten werden.The inside of the metal shell is flat, preferably full surface, connected to the foam body. In particular, if the metal shell has in cross-section inclined flanks to each other, a considerable stiffening can be achieved by the back-foaming. The dimensional stability of the metal shell improves considerably by the foaming. At the same time, the foam backing of the metal shell considerably improves the heat transfer coefficient, the so-called "K value" of the profile. In addition, the foam body achieves a significant reduction in the formation of condensation on the frame and in the transition to the glazing. The metal frame can be kept largely without condensation even without a heater.

Dem Metallmantel können an seiner Frontseite verschiedene Konturen gegeben werden. Nach einer vorteilhaften Ausführung der Erfindung besitzt der Metallmantel eine über die Breite und/oder die Höhe der Tür bauchig geformte Frontseite. Abgesehen von einer dynamischen Optik erhält die Tür hierdurch eine erhöhte Steifigkeit in sich. Die Krümmung ist hierbei nicht auf eine Krümmung im Querschnitt, wie sie auch bei Strangpressprofilen erhältlich wäre, beschränkt. Vielmehr sind die oberen und unteren Querschenkel des Metallrahmens an ihrer Frontseite in Längsrichtung der Querschenkel gekrümmt, d.h. die gesamte Frontseite des Metallmantels ist um eine im wesentlichen vertikale Krümmungsachse leicht gekrümmt, wodurch sich der Metallmantel plastisch von der planen Verglasung abhebt.The metal shell can be given different contours on its front side. According to an advantageous embodiment of the invention, the metal shell has a bellied over the width and / or height of the door front side. Apart from a dynamic look, this gives the door increased rigidity. The curvature is not limited to a curvature in the cross section, as would be available with extruded profiles limited. Rather, the upper and lower transverse legs of the metal frame are curved at their front in the longitudinal direction of the transverse legs, i. the entire front side of the metal shell is slightly curved around a substantially vertical axis of curvature, whereby the metal shell is plastically lifted from the planar glazing.

Um eine präzise scharflinige Optik auch am Übergang zur Verglasung zu erreichen, kann der Metallmantel einen Verglasungsausschnitt aufweisen, in den ein einstückig umlaufender Abdeckrahmen eingesetzt ist. Der Abdeckrahmen kann an den den Verglasungsausschnitt begrenzenden Rand des Metallmantels umlaufend anliegen, insbesondere kann er mit einer umlaufenden Nut auf den genannten Rand, der sich vorzugsweise im wesentlichen parallel zu der Verglasungsebene erstreckt, aufgesteckt werden, so dass der Metallmantelrand beidseitig von dem Abdeckrahmen umgriffen ist. Der Abdeckrahmen ist hierbei vorzugsweise einstückig mit leichter Übergröße gegenüber dem Verglasungsausschnitt ausgebildet. Er kann durch elastische Verformung dennoch in den Verglasungsausschnitt eingesetzt werden.In order to achieve a precise sharp-line appearance at the transition to the glazing, the metal shell may have a glazing cutout, in which an integrally encircling cover frame is inserted. The cover frame may rest against the edge of the metal shell delimiting the glazing cutout, in particular it may be plugged with a circumferential groove on said edge, which preferably extends substantially parallel to the glazing plane, so that the metal jacket edge is encompassed on both sides by the cover frame , The cover frame is in this case preferably formed integrally with slight oversize relative to the glazing cutout. He can still be used by elastic deformation in the glazing cutout.

Der Abdeckrahmen ist vorteilhafterweise frontseitig spaltfrei ausgebildet und schließt auch zur Verglasung weitgehend spaltfrei ab, wodurch Verschmutzungslinien vermieden und eine einwandfreie Optik auch über lange Zeit sichergestellt ist.The cover frame is advantageously formed frontally gap-free and also largely free of glass for glazing, thereby avoiding pollution and proper appearance is ensured over a long time.

Besitzt der Metallmantel die zuvor beschriebene Balligkeit quer über die gesamte Türbreite, kann der genannte Abdeckrahmen eine sich ändernde Tiefe besitzen, um die Krümmung der Frontseite des Metallrahmens gegenüber der planen Verglasung auszugleichen.If the metal shell has the above-described crowning over the entire width of the door, said cover frame may have a varying depth to compensate for the curvature of the front of the metal frame relative to the planar glazing.

Vorteilhafterweise kann der Verglasungsausschnitt des Metallmantels eckig ausgebildet sein. Im Gegensatz zu einem gerundeten Verglasungsausschnitt wird hier eine scharfe, präzise Optik erreicht.Advantageously, the glazing cutout of the metal shell can be angular. In contrast to a rounded glazing cut-out, a sharp, precise look is achieved here.

Es versteht sich jedoch, dass ein solcher eckiger Verglasungsausschnitt nicht zwangsweise vorgesehen sein muss. Gemäß einer alternativen Ausführung der Erfindung kann in den Metallmantel auch ein abgerundeter Verglasungsausschnitt eingebracht sein. Dies ermöglicht es insbesondere, an dem Metallmantel zum Verglasungsausschnitt hin einen gegenüber der Frontseite des Metallmantels abgewinkelten Randsteg vorzusehen. Ein solcher abgewinkelter Randsteg bewirkt eine Versteifung des Metallmantels in sich, die der Tür eine höhere Festigkeit gibt.It is understood, however, that such an angular glazing cutout does not necessarily have to be provided. According to an alternative embodiment of the invention, a rounded glazing cut-out can also be introduced into the metal casing. This makes it possible, in particular, to provide an edge web angled relative to the front side of the metal jacket on the metal jacket towards the glazing cutout. Such an angled edge web causes a stiffening of the metal shell in itself, which gives the door a higher strength.

Um einen Toleranzausgleich zwischen der Verglasung und dem Metallmantel zu ermöglichen, kann eine elastische Dichtung zwischengeschaltet werden. Diese kann grundsätzlich an der Frontseite der Verglasung vorgesehen sein, insbesondere wenn der zuvor beschriebene abgewinkelte Randsteg Verwendung findet. Um von außen eine präzise Optik zu erreichen, die durch die bisweilen unansehnliche Gummiwulst der Dichtung nicht gestört wird, wird der Toleranzausgleich jedoch auf die Innenseite verlegt. Die Verglasung kann auf ihrer Frontseite unmittelbar an dem den Verglasungsausschnitt begrenzenden Rand des Metallmantels oder dem zuvor beschriebenen darin eingesetzten Abdeckrahmen anstehen. Die elastische Dichtung zum Toleranzausgleich wird auf der Rückseite vorgesehen.To allow a tolerance compensation between the glazing and the metal shell, an elastic seal can be interposed. This can basically be provided on the front side of the glazing, in particular if the angled edge web described above is used. In order to achieve a precise appearance from the outside, which is not disturbed by the sometimes unsightly rubber bead of the seal, the tolerance compensation is, however, laid on the inside. The glazing may be present on its front side directly at the edge of the metal shell bounding the glazing cutout or the cover frame described above. The elastic seal for tolerance compensation is provided on the back.

Die Verglasung kann in verschiedener Art und Weise an dem Metallrahmen gelagert sein. Erfindungsgemäß ist für die Verglasung ein Verglasungshalter vorgesehen, der an der Rahmenversteifung befestigt ist. Wird die zuvor beschriebene Ausschäumung vorgesehen, ist der Verglasungshalter in den Schaumkörper eingeschäumt.The glazing may be mounted on the metal frame in various ways. According to the invention a glazing holder is provided for the glazing, which is fastened to the frame reinforcement. If the foaming described above is provided, the glazing holder is foamed into the foam body.

Vorteilhafterweise besitzt der Verglasungshalter von dem Metallrahmen nach innen vorspringende Auflagerschenkel, auf denen die Verglasung mit ihrer Flachseite aufliegt. Zwischen dem Auflagerschenkel und der Verglasung ist zweckmäßigerweise eine geeignete Verbindung vorgesehen. Insbesondere kann die Verglasung auf den Auflagerschenkel aufgeklebt sein. Durch das Verkleben des Glases mit diesen Teilen erhält die Tür ihre endgültige Steifigkeit.Advantageously, the glazing holder of the metal frame has inwardly projecting support legs, on which rests the glazing with its flat side. A suitable connection is expediently provided between the support leg and the glazing. In particular, the glazing may be glued to the support leg. By gluing the glass to these parts, the door gets its final rigidity.

Um eine gute Wärmedämmung zu erreichen, ist die Verglasung in Weiterbildung der Erfindung eine Mehrfachverglasung, bei der mehrere Glasscheiben voneinander beabstandet angeordnet sind. Gemäß einer Ausführung der Erfindung können drei Glasscheiben vorgesehen sein, die durch randseitig umlaufende Distanzstücke miteinander verbunden sind.In order to achieve a good thermal insulation, the glazing in a further development of the invention is a multiple glazing, in which a plurality of glass sheets are arranged spaced from each other. According to one embodiment of the invention, three glass sheets may be provided, which are interconnected by peripherally encircling spacers.

In Weiterbildung der Erfindung ist zwischen dem Metallmantel und der Verglasung und/oder zwischen dem Verglasungshalter und der Verglasung eine elastische Lippendichtung vorgesehen, die die Verglasung umgreift und mit ihrer elastischen Lippe Dickenänderungen der Verglasung ausgleicht. Dies verhindert einerseits Feuchtigkeitseintritt. Andererseits wird ein sauberer Abschluss geschaffen.In a further development of the invention, an elastic lip seal is provided between the metal jacket and the glazing and / or between the glazing holder and the glazing, which surrounds the glazing and compensates for changes in thickness of the glazing with its elastic lip. This prevents moisture on the one hand. On the other hand, a clean conclusion is created.

Die elastische Dichtung kann hierbei Abschnitte unterschiedlicher Härte und/oder Flexibilität aufweisen. Insbesondere kann eine weiche Dichtlippe an einem härteren Befestigungsabschnitt angeformt sein. Die Dichtung kann hierzu im Zweikomponentenverfahren aus verschiedenen Kunststoffen spritzgegossen sein. Ebenso möglich ist es, eine weichere Dichtlippe durch Koextrusion anzuformen. Vorteilhafterweise kann die Dichtung nicht nur die Verglasung abdichten, sondern für die Verglasung gleichzeitig eine Lagerungsfunktion übernehmen.The elastic seal may have sections of different hardness and / or flexibility. In particular, a soft sealing lip may be formed on a harder mounting portion. The seal can be injection molded in this two-component process of various plastics. It is also possible to form a softer sealing lip by coextrusion. Advantageously, the seal can not only seal the glazing, but at the same time take over a storage function for the glazing.

Um die Tür zu beleuchten, kann an dem Metallrahmen eine Beleuchtungseinrichtung vorgesehen sein, die Licht in die Verglasung leitet. Hierzu können im Übergangsbereich zwischen dem Metallrahmen und der Verglasung Leuchtdioden oder Leuchtstoffröhren vorgesehen werden. Gegebenenfalls kann hierdurch auf eine separate Beleuchtung des Geräteinnenraums verzichtet werden. Weitere Zusatzapplikationen, wie beispielsweise eine Rahmenheizung, können innerhalb des Metallmantels vorgesehen werden.To illuminate the door, a lighting device may be provided on the metal frame, which directs light into the glazing. For this purpose, light emitting diodes or fluorescent tubes can be provided in the transition region between the metal frame and the glazing. Optionally, this can be dispensed with a separate illumination of the device interior. Other additional applications, such as a frame heater, may be provided within the metal shell.

Soll die Tür oberhalb und/oder unterhalb ihrer Dichtung zum Gerätekorpus hin verlängert werden, um beispielsweise das Gerät abzudecken oder zu überragen, können Zusatzteile, insbesondere Türverlängerungen, an den Metallrahmen angebaut sein, welche dann ggf. auch zusätzliche Bauteile wie Schloss oder Thermometer aufnehmen können.If the door above and / or below its seal to the device body to be extended to cover, for example, the device or accessories, especially door extensions, can be attached to the metal frame, which can then possibly accommodate additional components such as lock or thermometer ,

Das in Figur 1 gezeigte Kühlgerät 1 besitzt einen im wesentlichen kubischen Gerätekorpus 2, der selbst frontseitig offen ausgebildet und durch eine Tür 3 verschließbar ist. Die Tür 3 ist in an sich bekannter Weise um eine vertikale Türschwenkachse schwenkbar an dem Gerätekorpus 2 gelagert, so dass sie mit Hilfe eines Türgriffs 4 um die in Figur 1 rechts liegende Schwenkachse auf- und zugeschwenkt werden kann.This in FIG. 1 shown cooling unit 1 has a substantially cubic device body 2, which is itself open at the front and closed by a door 3. The door 3 is mounted in a conventional manner about a vertical door pivot axis pivotally mounted on the device body 2, so that they with the help of a door handle 4 to the in FIG. 1 right pivot axis can be opened and closed.

Wie Figur 2 näher zeigt, ist die Türe 3 als Glastüre ausgebildet, die einen Metallrahmen 5 aufweist, in den eine Verglasung 6 eingesetzt ist. Bei solchen Glastüren ist der Metallrahmen regelmäßig recht schmal ausgebildet. Die Verglasung 6 nimmt regelmäßig mehr als 2/3 der Breite bzw. der Höhe der Tür ein.As FIG. 2 shows closer, the door 3 is formed as a glass door, which has a metal frame 5, in which a glazing 6 is inserted. In such glass doors, the metal frame is regularly made quite narrow. The glazing 6 regularly occupies more than 2/3 of the width or the height of the door.

Der Metallrahmen 5 besteht aus einem umlaufend integral einstückigen Metallmantel 7, der aus einem Stück, insbesondere aus einer einstückigen Blechplatine, in einem spanlosen Umformprozess gefertigt ist. Insbesondere kann der Metallmantel 7 tiefgezogen oder gebogen und gebördelt sein. Vorteilhafterweise besitzt hierdurch der Metallmantel 7 zumindest auf seiner sichtbaren Vorderseite, die Figur 2 zeigt, keine Naht- oder Stoßstellen, wie dies bei herkömmlichen Metallglastüren der Fall ist, die aus mehreren Metallrahmenstücken zusammengesetzt sind.The metal frame 5 consists of a circumferentially integrally integral metal shell 7, which is made of one piece, in particular of a one-piece sheet metal blank, in a chipless forming process. In particular, the metal shell 7 can be deep-drawn or bent and crimped. Advantageously, thereby has the metal shell 7 at least on its visible front, the FIG. 2 shows, no seams or joints, as is the case with conventional metal glass doors, which are composed of several metal frame pieces.

Im Bereich des oberen Querstücks des Metallrahmens 5 sind in den Metallmantel 7 Ausstanzungen für ein Thermometer 8 sowie ein Schloss 9 eingebracht.In the region of the upper crosspiece of the metal frame 5 7 punched holes for a thermometer 8 and a lock 9 are introduced into the metal shell.

Bei gebördelter Ausführung des Metallmantels 7 können stirnseitig Abdeckungen aufgesetzt werden, um die Blechkanten und die Abstützung zu verdecken und die Optik zu verbessern.When flanged execution of the metal shell 7 covers can be placed on the front side to cover the sheet edges and the support and to improve the appearance.

Um die Tür 3 gegenüber dem Gerätekorpus 2 abzudichten, sitzt umlaufend um die Verglasung 6 herum auf dem Metallrahmen 5 rückseitig eine Dichtung 14 auf, die beim Schließen der Tür gegen den Gerätekorpus 2 gedrückt wird.In order to seal the door 3 with respect to the appliance body 2, a gasket 14, which is pressed against the appliance body 2 when closing the door, sits around the glazing 6 on the metal frame 5 at the rear.

Soll die Tür 3 oberhalb und/oder unterhalb der Dichtung 14 verlängert werden, um beispielsweise das Gerät abzudecken oder zu überragen, können Zusatzteile verbaut werden, welche dann ggf. die zusätzlichen Bauteile wie das Schloss 9 oder das Thermometer 8 aufnehmen können.If the door 3 is to be extended above and / or below the seal 14 in order, for example, to cover or project beyond the device, additional parts can be installed which can then possibly accommodate the additional components such as the lock 9 or the thermometer 8.

Wie Figur 2 zeigt, ist der Metallmantel 7 an seiner Frontseite über die gesamte Breite der Tür leicht ballig ausgebildet. Die oberen und unteren Querschenkel 11 sind über ihre Länge, d.h. gemäß Figur 1 von links nach rechts, leicht gekrümmt. Der sich hieraus ergebende Unterschied zu der planen Verglasung 6 hin wird entweder durch einen in den Verglasungsausschnitt eingesetzten Abdeckrahmen oder durch zur Frontseite abgewinkelte Randstege des Metallmantels ausgeglichen, wie noch näher beschrieben wird.As FIG. 2 shows, the metal shell 7 is slightly convex at its front over the entire width of the door. The upper and lower transverse legs 11 are over their length, ie according to FIG. 1 from left to right, slightly curved. The resulting difference from the planar glazing 6 is compensated for either by a cover frame inserted into the glazing cut-out or by the edge webs of the metal shell angled towards the front, as will be described in more detail.

Wie Figur 3 zeigt, ist der Metallmantel 7 in die gewünschte Querschnittskontur spanlos umgeformt worden, so dass der Metallmantel 7 einen frontseitigen Abschnitt 16, einen schmalseitigen Abschnitt 17 sowie einen rückseitigen Abschnitt 18 umfasst. Der von dem Metallmantel 7 auf diese Weise begrenzte rückseitige Hohlraum ist ausgeschäumt, so dass sich ein umlaufender Schaumkörper 19 vollflächig an die rückseitige Wandung des Metallmantels 7 schmiegt und eine geschlossene Rahmenversteifung bildet, die die Maßhaltigkeit des Metallmantels beträchtlich verbessert. Es versteht sich, dass durch die Hinterschäumung des Metallmantels 7 auch eine verbesserte Wärmedämmung erreicht wird. Der Metallrahmen 5 besitzt einen wesentlich verbesserten K-Wert.As FIG. 3 shows, the metal shell 7 has been formed into the desired cross-sectional contour without cutting, so that the metal shell 7 a front-side portion 16, a narrow-side portion 17 and a rear portion 18 includes. The limited by the metal shell 7 in this way back cavity is filled with foam, so that a circumferential foam body 19 over the entire surface of the rear wall of the metal shell 7 nestles and forms a closed frame stiffening, which significantly improves the dimensional stability of the metal shell. It is understood that by the foam backing of the metal shell 7 also improved thermal insulation is achieved. The metal frame 5 has a much improved K value.

Wie Figur 3 zeigt, ist in den Schaumkörper 19 ein Verglasungshalter 12 eingeschäumt, der einerseits den nach innen vorspringenden Auflagerschenkel 13 für die Verglasung 6 sowie einen hierzu L-förmig abgewinkelten Abschlussschenkel 20 besitzt. Das als Verglasungshalter 12 dienende Profil begrenzt den Schaumkörper 19 zu der von dem Metallmantel 7 hin nicht begrenzten offenen Seite des Metallrahmens 5.As FIG. 3 shows, in the foam body 19, a glazing holder 12 is foamed, on the one hand has the inwardly projecting support legs 13 for the glazing 6 and a L-shaped angled end leg 20. The serving as glazing holder 12 profile limits the foam body 19 to the non-limited by the metal shell 7 open side of the metal frame fifth

Die Verglasung 6 besteht aus einer Dreifach-Verglasung umfassend drei Glasscheiben 21, 22, 23, die zueinander parallel angeordnet sind und durch Distanzstücke 24 und 25 miteinander verbunden sind. Die Distanzstücke 24 und 25 verlaufen vorteilhafterweise rundum, so dass sich ein insgesamt abgeschlossenes Isolierverglasungspaket ergibt. Die Verglasung 6 ist in den Verglasungshalter 12 eingesetzt und kann dort an dem Auflagerschenkel 13 durch eine Verklebung 26 befestigt sein. Gegenüber dem Begrenzungsschenkel 20 ist die Verglasung 6 durch eine umlaufende Dichtung 27 abgedichtet.The glazing 6 consists of a triple glazing comprising three glass panes 21, 22, 23, which are arranged parallel to each other and are interconnected by spacers 24 and 25. The spacers 24 and 25 advantageously run all around, so that there is a total completed insulating glazing package. The glazing 6 is inserted into the glazing holder 12 and may there be secured to the support leg 13 by a bond 26. Compared to the limiting leg 20, the glazing 6 is sealed by a circumferential seal 27.

Der Verglasungshalter 12 mit der darin eingesetzten Verglasung 6 wird von der Rückseite her in die offene Seite des Metallmantels 7 eingesetzt, wobei der Rand der zentralen Ausstanzung des Metallmantels 7 für die Verglasung 6 durch eine weitere Dichtung 28, die auf dem Rand des Metallmantels 7 sitzt, abgedichtet und sauber abgeschlossen wird. Sodann wird nach Einsetzen der Verglasung mit dem daran vorgesehenen Verglasungshalter 12 der sich rückseitig im Metallmantel 7 bildende Hohlraum ausgeschäumt, so dass der Verglasungshalter 12 in den Schaumkörper 19 eingeschäumt wird. Wie Figur 3 zeigt, umfasst der Verglasungshalter 12 einen Stützabschnitt 29, der auf dem rückseitigen Schenkelabschnitt 18 des Metallmantels 7 ruht. Auf diesem Stützabschnitt 29 ist die Türdichtung 14 befestigt, die die Tür 3 gegenüber dem Stützkorpus 2 abdichtet.The glazing holder 12 with the glazing 6 inserted therein is inserted from the rear into the open side of the metal shell 7, wherein the edge of the central punching of the metal shell 7 for the glazing 6 by a further seal 28 which sits on the edge of the metal shell 7 , sealed and finished clean. Then, after inserting the glazing with the glazing holder 12 provided thereon, the cavity forming the rear side in the metal jacket 7 is filled with foam, so that the glazing holder 12 is foamed into the foam body 19. As FIG. 3 shows, the glazing holder 12 comprises a support portion 29 which rests on the rear leg portion 18 of the metal shell 7. On this support portion 29, the door seal 14 is fixed, which seals the door 3 relative to the support body 2.

Wie Figur 3 zeigt, ist der Rand 40 des Metallmantels 7, der den Verglasungsausschnitt 41 des Metallmantels begrenzt, gegenüber der Frontseite des Metallmantels 7 nach innen hin abgewinkelt, wobei der letzte Randsteg wiederum im wesentlichen parallel zur Verglasungsebene abgewinkelt ist. Durch die abgewinkelte Ausbildung des Randabschnittes 40 erhält der Metallmantel 7 eine beträchtlich erhöhte Steifigkeit. Die Dichtung 28 sitzt auf dem Randsteg 40. Sie kann umlaufend auf diesen aufgesteckt sein, wobei sich Dichtlippen der Dichtung 28 auf der Frontseite der Verglasung abstützen und einen Toleranzausgleich ermöglichen. Hierbei sind nicht nur Fertigungstoleranzen von Bedeutung. Vielmehr kann sich die Mehrfachverglasung durch Druckänderungen, beispielsweise beim Transport in größeren Höhen, in ihrer Dicke ändern, so dass ein Toleranzausgleich nötig ist. Bei dieser Ausführung der Glastür ist der Verglasungsausschnitt 41 vorteilhafterweise nicht richtig eckig, sondern abgerundet ausgebildet, um die Ausbildung des Randsteges zu ermöglichen.As FIG. 3 shows, the edge 40 of the metal shell 7, which limits the glazing cutout 41 of the metal shell, angled towards the front of the metal shell 7 inwards, wherein the last edge web is in turn angled substantially parallel to the glazing plane. Due to the angled design of the edge portion 40 of the metal shell 7 receives a considerably increased rigidity. The seal 28 is seated on the edge web 40. It can be circumferentially attached to this, with sealing lips of the seal 28 are supported on the front side of the glazing and allow tolerance compensation. Not only are manufacturing tolerances important here. Rather, the multiple glazing may change in thickness due to pressure changes, for example, during transport at high altitudes, so that a tolerance compensation is necessary. In this version the glass door is the glazing cutout 41 advantageously not right angular, but rounded to allow the formation of the edge web.

Die Ausführung nach Figur 4 umfasst ebenfalls den gemäß Figur 2 über die Türbreite balligen, im Querschnitt dreischenklig gebogenen Metallmantel 7, in dessen zentrale Ausstanzung die Verglasung 6 mit dem daran befestigten Verglasungshalter 12 eingesetzt ist. Auch hier sitzt der Verglasungshalter 12 mit einem Stützabschnitt 29 auf dem rückseitigen Schenkelabschnitt 18 des Metallmantels 7. Der Verglasungshalter 12 ist jedoch sozusagen umgekehrt ausgebildet. Der Auflagerschenkel 13, an dem die Verglasung 6 aufliegt, erstreckt sich an dem frontseitigen Ende des Abschlussschenkels 20 des Verglasungshalters 12. Zwischen dem Auflagerschenkel 13 und dem Metallmantel 7 ist eine gewissermaßen als Labyrinthdichtung ausgebildete Verbindung in Form eines Abdeckrahmens 42 vorgesehen. Ein den Abdeckrahmen 42 bildendes Profilstück 31 sitzt klemmend auf dem an die zentrale Ausstanzung angrenzenden Rand des Metallmantels 7 und erstreckt sich zur Verglasung 6 hin, wobei zur Verglasung 6 hin das Profilstück 13 gabelförmig ausgebildet ist. Innerhalb des Gabelprofils erstreckt sich ein an den Auflagerschenkel 13 angeformter Randsteg 32. Der Abdeckrahmen 42 ist umlaufend einstückig ausgebildet und besitzt gegenüber dem Verglasungsausschnitt 41 eine leichte Übergröße. Wie Figur 4 zeigt, erstreckt sich der den Verglasungsausschnitt 41 begrenzende Rand 40 ohne Abwinklungen, d.h. im wesentlichen parallel zu der Verglasungsebene. Der Abdeckrahmen 42 besitzt eine umlaufende Nut, mit der er unter elastischer Verformung des Abdeckrahmens 42 auf den Rand 40 aufsteckbar ist, so dass dieser beidseitig umgriffen ist. Durch den Abdeckrahmen 42 wird insbesondere auch die aus Figur 2 ersichtliche Krümmung des Metallmantels zu der Verglasung hin ausgeglichen. Durch die Krümmung des Metallmantels ändert sich der Abstand des Rands 40 von der Verglasungsebene. Der Abdeckrahmen 42 besitzt eine sich über die Länge der Querschenkel 11 ändernde Tiefe, d.h. seine Rückseite, die der Verglasung zugewandt ist, bildet eine ebene Fläche, wodurch ein Spalt zwischen der Verglasung und dem entsprechenden Schenkel des Profilstücks 31 minimiert ist. Durch den einstückigen Abdeckrahmen 42, der umlaufend an dem Rand 40 des Metallmantels 7 anliegt, kann eine scharfe präzise Optik erreicht werden. Insbesondere kann durch die fehlende Abknickung des Randes 40 eine scharfkantige, eckige Ausbildung des Verglasungsausschnittes 41 erreicht werden.The execution after FIG. 4 also includes the according to FIG. 2 crowned over the door width, in cross-section three-legged bent metal shell 7, in the central punched the glazing 6 is used with the glazing holder 12 attached thereto. Again, the glazing holder 12 is seated with a support portion 29 on the rear leg portion 18 of the metal shell 7. However, the glazing holder 12 is formed, so to speak vice versa. The support arm 13, on which the glazing 6 rests, extends at the front end of the end leg 20 of the glazing holder 12. Between the support leg 13 and the metal shell 7, a connection in the form of a cover frame 42 is provided, as it were formed as a labyrinth seal. A profile piece 31 forming the cover frame 42 sits in a clamping manner on the edge of the metal jacket 7 adjoining the central punched-out area and extends toward the glazing 6, the profile piece 13 being fork-shaped towards the glazing 6. Within the fork profile, an integrally formed on the support leg 13 edge web 32 extends. The cover 42 is integrally formed circumferentially and has over the glazing cutout 41 a slight oversize. As FIG. 4 shows, the glazing cutout 41 bounding edge 40 extends without angling, ie, substantially parallel to the glazing plane. The cover frame 42 has a circumferential groove, with which it can be plugged under elastic deformation of the cover 42 on the edge 40, so that it is embraced on both sides. By the cover 42 is in particular also made of FIG. 2 apparent curvature of the metal shell to the glazing out balanced. The curvature of the metal shell changes the distance of the edge 40 from the glazing plane. The cover frame 42 has a depth that changes along the length of the transverse legs 11, ie its rear side, which faces the glazing, forms a flat surface, whereby a gap between the glazing and the corresponding leg of the profile piece 31 is minimized. By the one-piece cover frame 42, the circumferential is applied to the edge 40 of the metal shell 7, a sharp precise optics can be achieved. In particular, can be achieved by the lack of bending of the edge 40 a sharp-edged, angular formation of the glazing cutout 41.

Der Toleranzausgleich für die Verglasung 6 ist bei der Ausführung nach Figur 4 sozusagen nach hinten, d.h. auf die Innenseite der Tür verlegt. Die Verglasung 6 wird rückseitig durch eine umlaufende Dichtung 33 in dem Verglasungshalter 12 gehalten. Wie Figur 4 zeigt, ist die Dichtung 33 in dem Verglasungshalter 12 einrastbar und deckt den Rand der Verglasung 6 ab. Die umlaufende Dichtung 33 ist vorteilhafterweise aus verschiedenen Kunststoffen im Zweikomponentenverfahren spritzgegossen oder koextrudiert. Insbesondere kann die Dichtung 33 eine elastische Dichtlippe 43 besitzen, die an einen steiferen Befestigungsabschnitt 44 angeformt ist. Der steifere Befestigungsabschnitt 44 ist in der gezeichneten Ausführung mit einem Rastarm versehen, mit Hilfe dessen die Dichtung 33 mit dem Verglasungshalter 12 verrastbar ist. Durch die elastische Dichtlippe 43 ist der für die Verglasung 6 nötige Toleranzausgleich sichergestellt. Dehnt sich die Verglasung bei Druckminderungen in ihrer Dicke aus, gibt die Dichtlippe 43 entsprechend nach.The tolerance compensation for the glazing 6 is in the execution after FIG. 4 so to speak to the rear, ie laid on the inside of the door. The glazing 6 is held at the rear by a circumferential seal 33 in the glazing holder 12. As FIG. 4 shows the seal 33 in the glazing holder 12 can be latched and covers the edge of the glazing 6 from. The peripheral seal 33 is advantageously injection molded or coextruded from a variety of plastics in the two-component process. In particular, the seal 33 may have an elastic sealing lip 43, which is formed on a stiffer mounting portion 44. The stiffer mounting portion 44 is provided in the illustrated embodiment with a locking arm, by means of which the seal 33 can be latched to the glazing holder 12. By the elastic sealing lip 43 of the required for the glazing 6 tolerance compensation is ensured. If the glazing expands in thickness when the pressure is reduced, the sealing lip 43 gives way accordingly.

Auch bei der Ausführung nach Figur 4 ist der Metallmantel 7 rückwandseitig ausgeschäumt. In den sich bildenden Schaumkörper 19 ist der Verglasungshalter 12 eingeschäumt.Also in the execution after FIG. 4 the metal shell 7 is foamed on the back wall side. In the forming foam body 19 of the glazing holder 12 is foamed.

Durch den durchgehenden Metallmantel 7 wird eine homogene und edle Optik an der Sichtfläche erreicht, die nunmehr aus einem vollflächig gleich gefärbten und ausgerichteten Material besteht. Farbliche Abweichungen, sichtbare Spaltbildung oder Stoßstellen werden hierdurch ausgeschlossen. Zudem besteht die Möglichkeit der Bedruckung, Lackierung oder Thermosublimation, wodurch die sichtbare Oberfläche des Metallrahmens an kundenspezifische Wünsche angepasst werden kann. Selbstverständlich ist auch eine farbliche Anpassung der Glastür an den Gerätekorpus 2 möglich, was bislang aufgrund verschiedener Materialien nur bedingt möglich war.Through the continuous metal shell 7, a homogeneous and noble appearance is achieved on the visible surface, which now consists of a full-surface same colored and aligned material. Color deviations, visible gaps or joints are thereby excluded. In addition, there is the possibility of printing, painting or thermal sublimation, whereby the visible surface of the metal frame can be adapted to customer requirements. Of course, a color adjustment of the glass door to the device body 2 is possible, which was previously only possible due to various materials.
