Description

Die Erfindung betrifft ein wärmeisolierendes Gehäuse für einen thermisch isolierenden Nutzraum, angeordnet in einem Gerät, wie einem Haushaltskühl- oder -gefriergerät, einem Haushaltsbackofen oder dergleichen mit einer Gehäuseaußenwand, einer dazu beabstandeten Gehäuseinnenwand, welche zusammen einen Zwischenraum umschließen, welcher zumindest über eine Anschlußstelle evakuierbar ist und welcher mit einem evakuierbaren Wärmeisolationsmaterial zur Abstützung der den Zwischenraum umschließenden Wände verfüllt ist.The invention relates to a heat-insulating housing for a thermally insulating usable space, arranged in a device such as a household refrigerator or freezer, a household oven or the like with a housing outer wall, one spaced apart therefrom Housing inner wall, which together enclose an intermediate space, which at least is evacuated via a connection point and which with an evacuable heat insulation material is filled to support the walls surrounding the intermediate space.

Es ist bekannt, bei auf Vakuumisolationstechnik basierenden wärmeisolierenden Gehäusen, die zum Zwecke der Isolation zu evakuierenden, von den Gehäuseaußenwänden hermetisch umschlossenen Zwischenräume mit Wärmeisolationsmaterial zu verfüllen. Dies dient neben einer zusätzlichen Wärmeisolation vor allem noch dazu, die den zu evakuierenden Hohlraum schalenartig umschließenden Gehäusewände gegen den aufgrund der Druckabsenkung innerhalb des Hohlraumes sich ergebenden Druckunterschied zur Außenatmosphäre zu abstützen. Das zur Abstützung eingebrachte Wärmeisolationsmaterial bringt jedoch mit sich, daß die zur Erzeugung eines für Wärmeisolationszwecke ausreichenden Vakuums erforderlichen Evakuierzeiten deutlich erhöht sind.It is known, in the case of heat-insulating housings based on vacuum insulation technology, those to be evacuated for the purpose of insulation, hermetically sealed from the housing outer walls to fill enclosed spaces with heat insulation material. This serves alongside an additional heat insulation, especially the cavity to be evacuated shell-like enclosing housing walls against the due to the pressure drop inside to support the resulting pressure difference from the cavity to the outside atmosphere. However, the thermal insulation material brought in for support entails that the necessary to generate a sufficient vacuum for thermal insulation purposes Evacuation times are significantly increased.

Der Erfindung liegt die Aufgabe zugrunde, bei einem Gehäuse gemäß dem Oberbegriff des Anspruchs 1 Maßnahmen vorzuschlagen, aufgrund welcher auf einfache Weise die Nachteile des Standes der Technik vermieden sind. The invention has for its object in a housing according to the preamble of Claim 1 to propose measures on the basis of which the disadvantages are simple of the prior art are avoided.

Diese Aufgabe wird gemäß der Erfindung dadurch gelöst, daß innerhalb des Zwischenraumes ein zumindest teilweise innerhalb des Wärmeisolationsmaterials verlaufendes Kanalsystem vorgesehen sind, welches den Zwischenraum zumindest weitestgehend flächendeckend durchzieht und welches mit dem Evakuierstutzen strömungstechnisch verbunden ist.This object is achieved according to the invention in that within the space one that runs at least partially within the heat insulation material Channel system are provided, which at least largely the space area-wide and which flows with the evacuation nozzle connected is.

Die erfindungsgemäße Einbringung eines Kanal- oder Rohrleitungssystems in dem zu evakuierenden Zwischenraum bewirkt durch die deutliche Verkürzung der Evakuierwege eine gezielte, weitestgehend ungehinderte Luftabführung und damit Druckabsenkung, des mit Wärmeisolationsmaterial verfüllten Materials. Durch die Verbesserung der Luftabführung ergibt sich eine drastische Reduzierung der Evakuierzeit eines zu evakuierenden Zwischenraumes, wodurch die Fertigungszeit eines auf Vakuumisolationsbasis herzustellenden Gehäuses deutlich verringert und somit der Fertigungsausstoß für derartige Gehäuse in gleichem Maße erhöht ist. Ferner lassen sich solche Kanal- oder Rohrleitungssysteme durch ihren zusammenhängenden Aufbau besonders einfach und zielgerichtet innerhalb des zu evakuierenden Hohlraumes positionieren. Außerdem lassen sich die zur effektiven Evakuierung abzuführenden Luftmengen auf einfache Weise durch die Kanalabmessung gezielt beeinflußen.The introduction of a sewer or piping system according to the invention evacuating space caused by the significant shortening of the evacuation routes a targeted, largely unhindered air discharge and thus pressure reduction, the material filled with thermal insulation material. By improving the air discharge there is a drastic reduction in the evacuation time of an evacuated person Intermediate space, whereby the manufacturing time of a vacuum insulation based Housing significantly reduced and thus the production output for such Housing is increased to the same extent. Such duct or piping systems can also be used Thanks to their coherent structure, they are particularly simple and targeted within position of the cavity to be evacuated. They can also be used for effective evacuation of air to be discharged in a simple manner through the Target channel dimensions.

Nach einer bevorzugten Ausführungsform des Gegenstandes der Erfindung ist vorgesehen, daß zur strömungstechnischen Anbindung des Kanalsystems an den Evakuierstutzen wenigstens eine Sammelstelle vorgesehen ist, in welcher die evakuierstutzenseitigen Enden des Kanalsystems münden.According to a preferred embodiment of the subject matter of the invention, that for the fluidic connection of the sewer system to the evacuation nozzle at least a collection point is provided, in which the evacuation nozzle ends of the channel system.

Durch eine solche Maßnahme läßt sich der Evakuierstutzen hinsichtlich seiner Abmessungen besonders klein und unauffällig gestalten. Gleichzeitig ergibt sich hierdurch auch noch eine deutliche Vereinfachung der strömungstechnischen Anbindung an den Evakuierstutzen, so daß potentielle Leckmöglichkeiten und daraus resultierende Leckverluste drastisch reduziert sind.With such a measure, the evacuation nozzle can be dimensioned make it particularly small and inconspicuous. At the same time this also results a significant simplification of the fluidic connection to the evacuation nozzle, so that potential leakage opportunities and resulting leakage losses are drastically reduced are.

Besonders zweckmäßig ist eine Sammelstelle für die evakuierstutzenseitigen Enden des Kanalsystems ausgebildet, wenn nach einer nächsten vorteilhaften Ausgestaltung des Gegenstandes der Erfindung vorgesehen ist, daß die Sammelstelle als ein zumindest im Nahbereich des Evakuierstutzens angeordneter Vorhof ausgebildet ist. A collection point for the ends of the evacuation nozzle is particularly useful Channel system formed if according to a next advantageous embodiment of the The object of the invention is that the collection point as an at least Atrium arranged in the vicinity of the evacuation nozzle is formed.

Strömungstechnisch eine besonders günstige Anbindung des als Sammelstelle ausgebildeten Vorhofes an den Evakuierstutzen ergibt sich, wenn nach einer nächsten vorteilhaften Ausgestaltung des Gegenstandes der Erfindung vorgesehen ist, daß der Vorhof den Evakuierstutzen ringförmig umgibt. Durch eine derartige Lösung ist zu dem auf besonders einfache Art und Weise die Gefahr potentieller Lackagen deutlich verringert.In terms of flow technology, this is a particularly favorable connection to the one designed as a collection point Atrium at the evacuation nozzle arises if after a next advantageous Embodiment of the subject of the invention is provided that the atrium the evacuation nozzle surrounds in a ring. Such a solution is particularly simple Way significantly reduces the risk of potential paintwork.

Besonders effektiv und zeitsparend läßt sich ein Evakuiervorgang eines mit Wärmeisolationsmaterial verfüllten Zwischenraumes eines wärmeisolierenden Gehäuses durchführen, wenn nach einer nächsten bevorzugten Ausführungsform des Gegenstandes der Erfindung vorgesehen ist, daß das Kanalsystem zumindest teilweise in das Wärmeisolationsmaterial eingebracht ist.An evacuation process with thermal insulation material can be particularly effective and time-saving fill the space between a heat-insulating housing, if according to a next preferred embodiment of the subject of the invention it is provided that the channel system is at least partially in the heat insulation material is introduced.

Entsprechend einer weiteren bevorzugten Ausführungsform des Gegenstandes der Erfindung ist vorgesehen, daß das Wärmeisolationsmaterial aus offenzelligen, plattenförmigen Schaumwerkstoffen gebildet ist, in welche das Kanalsystem spanabhebend eingebracht ist.According to a further preferred embodiment of the subject of the invention it is provided that the heat insulation material made of open-cell, plate-shaped Foam materials is formed, in which the channel system is machined.

Durch eine derartige Maßnahme erübrigt sich die Bereitstellung eines zusätzlichen, innerhalb des zu evakuierenden Zwischenraumes zu positionierenden und dadurch den Fertigungsablauf hemmenden Kanal- oder Rohrleitungssystems. Ferner ergibt sich durch eine solche Lösung die Möglichkeit, kostengünstige, herstellungsbedingt an seinen Außenflächen ausgebildete plattenförmige Schaumwerkstoffe einsetzen zu können, welche durch die zielgerichtete spanabhebende Bearbeitung an dem eine drastische Reduzierung der Evakuierzeit herbeiführenden Stellen offenzellig gestaltet sind. Darüberhinaus ist durch die Ausgestaltung des Wärmeisolationsmaterials mit randoffenen Luftkanälen erreicht, daß aufgrund der hierdurch erzielten Oberflächenvergrößerung des Wärmeisolationsmaterials eine Faltenbildung an der Gehäuseaußenwand und an der Gehäuseinnenwand nach dem Evakuiervorgang des wärmeisolierenden Gehäuses vermieden ist.Through such a measure, the provision of an additional, within of the space to be evacuated and thereby the manufacturing process obstructing sewer or pipe system. Such a solution also results the possibility of inexpensive, manufacturing-related trained on its outer surfaces to be able to use plate-shaped foam materials, which through the targeted machining on the drastic reduction in evacuation time Places are designed with open cells. In addition, the design of the Thermal insulation material with open air channels achieved that due to this achieved surface enlargement of the thermal insulation material wrinkling on the Housing outer wall and on the housing inner wall after the evacuation of the heat insulating Housing is avoided.

Darüberhinaus ist es bei Polystyrol möglich, das Kanalsystem spanlos durch Verformung seiner Oberfläche zu erzeugen.In addition, with polystyrene, it is possible to chipless the duct system by deformation to produce its surface.

Gemäß einer alternativen Ausführungsform des Gegenstandes der Erfindung ist vorgesehen, daß das Wärmeisolationsmaterial aus plattenförmigen Glasfaserwerkstoffen gebildet ist, in welche das Kanalsystem eingeformt ist. According to an alternative embodiment of the subject matter of the invention, that the heat insulation material is formed from plate-shaped glass fiber materials, in which the channel system is molded.

Durch eine derartige Ausgestaltung der Glasfasermatten erübrigt sich zum Zwecke einer drastischen Reduzierung der Evakuierzeit die Einbringung zusätzlicher, innerhalb des zu evakuierenden Zwischenraumes fertigungsbedingt noch aufwendig einzubringender Abstandshalter zwischen den Glasfasermatten. Durch die Oberflächenvergrößerung an den Glasfasermatten der darin spanlos eingeformten randoffenen Luftkanäle ergibt sich eine faltenfreie Anlage der dünnwandigen Gehäuse innen- und Gehäußeaußenwand an die Oberfläche des Wärmeisolationsmaterials.Such a configuration of the glass fiber mats makes one unnecessary drastic reduction in evacuation time, the introduction of additional, within the evacuating space due to manufacturing still difficult to install spacers between the glass fiber mats. By enlarging the surface of the Glass fiber mats of the open-edged air channels formed without cutting result in a Wrinkle-free application of the thin-walled housing inside and outside of the housing to the Surface of the thermal insulation material.

Gemäß einer weiteren alternativen Ausführungsform des Gegenstandes der Erfindung ist vorgesehen, daß das Wärmeisolationsmaterial als evakuierbares Schüttgut ausgebildet ist, innerhalb welchem ein vorgefertigtes Kanalsystem eingebettet ist.According to a further alternative embodiment of the subject of the invention provided that the heat insulation material is designed as an evacuable bulk material, within which a prefabricated duct system is embedded.

Hierdurch wird die bei als Schüttgut wie Aerogelen oder Kieselgur an sich notwendige Evakuierzeit eines mit diesem Schüttgut fest verfüllten Zwischenraumes eines warmeisolierenden Gehäuses stark herabgesetzt.This makes it necessary for bulk materials such as airgels or diatomaceous earth Evacuation time of an interstice firmly filled with this bulk material heat-insulating housing greatly reduced.

Eine besonders deutliche Verringerung der Evakuierzeit infolge einer besonders starken Verkürzung der Evakuierwege ergibt sich, wenn nach einer letzten bevorzugten Ausführungsform des Gegenstandes der Erfindung vorgesehen ist, daß das vorgefertigte Kanalsystem zumindest über einen Teil seiner Leitungslänge und seines Leitungsumfanges mit Durchbrüchen versehen ist.A particularly significant reduction in the evacuation time due to a particularly strong one Shortening of the evacuation routes results if according to a last preferred embodiment the object of the invention is provided that the prefabricated channel system at least over part of its length and scope Breakthroughs is provided.

Gemäß Figur 1 ist ein Haushaltskühlschrank 10 mit einem wärmeisolierenden Gehäuse 11 gezeigt, welches einen dünnwandigen folienähnlichen Metallaußenmantel 12 und einen dazu beabstandeten, den Innenraum des Gehäuses 11 auskleidenden Metallinnenverkleidung 13 gleicher Materialstärke gebildet ist. Diese ist an ihren freien Rändern mit den freien Rändern des Metallaußenmantels 12 über einen Verbindungsrahmen 14 vakuumdicht verbunden, wodurch zwischen dem Metallaußenmantel 12 und der Metallinnenverkleidung 13 ein hermetisch umschlossener vakuumdichter Zwischenraum 15 gebildet ist. Dieser ist mit offenzelligem Wärmeisolationsmaterial 16 verfüllt, welches beispielsweise aus offenzelligem Polyurethanschaum bzw. Polyisocyanuratschaum, Polystyrolschaum oder anderem offenzelligem Polymerschäumen gebildet ist und welches zu Plattenkörpern geformt ist, von denen einer als Deckenisolierkörper 17, einer als Rückwandisolierkörper 18, ein weiterer als Bodenisolierkörper 19 dient, während zwei spiegelbildlich ausgebildete Isolierplatten als Seitenwandisolierkörper 20 vorgesehen sind. Die Isolierkörper 17 bis 20 sind hinsichtlich ihrer Plattenstärke auf den Abstand zwischen dem Metallaußenmantel 12 und der Metallinnenverkleidung 13 abgestimmt und hinsichtlich ihrer Körperfläche und Körpergeometrie an die Fläche und Geometrie der entsprechenden Gehäusewandung angepaßt. Die Isolierkörper für die einzelnen Wandabschnitte des wärmeisolierenden Gehäuses 11 sind an ihrer der Metallinnenverkleidung 13 zugewandten Seite mit durch spanende Verarbeitungsverfahren wie Fräsen, Sägen oder dergleichen hergestellten, zur Metallinnenverkleidung 13 hin randoffen ausgebildeten Kanälen 21 versehen.According to FIG. 1, there is a household refrigerator 10 with a heat-insulating housing 11 shown, which has a thin-walled sheet-like metal outer jacket 12 and one spaced metal inner lining 13 lining the interior of the housing 11 the same material thickness is formed. This is at its free edges with the free edges of the metal outer jacket 12 connected vacuum-tight via a connecting frame 14, whereby between the metal outer shell 12 and the metal inner lining 13 Hermetically enclosed vacuum-tight space 15 is formed. This is with filled open-cell heat insulation material 16, which for example consists of open-cell Polyurethane foam or polyisocyanurate foam, polystyrene foam or other open-cell polymer foam is formed and which is shaped into sheet bodies, from which one as a ceiling insulating body 17, one as a rear wall insulating body 18, another as Floor insulating body 19 serves as two mirror-image insulating plates as Sidewall insulating body 20 are provided. The insulators 17 to 20 are regarding their plate thickness on the distance between the metal outer jacket 12 and the Metal inner lining 13 matched and in terms of their body area and Body geometry to the surface and geometry of the corresponding housing wall customized. The insulating body for the individual wall sections of the heat insulating Housing 11 are on their side facing the metal inner panel 13 with Machining processes such as milling, sawing or the like produced for Metal inner lining 13 provided channels 21 open to the edge.

Wie insbesondere aus Fig.2 hervorgeht, sind die Kanäle 21 in annähernd gleichen Abständen flächendeckend über die Isolierkörper 17 bis 20 angeordnet und über den Rückwandisolierkörper 18 zu einem zusammenhängenden Kanalsystem verbunden. Zu diesem Zweck sind die Kanäle 21 am Rückwandisolierkörper 18 netzartig angelegt, wobei die freien Enden der netzartig angelegten Kanäle 21 am Rückwandisolierkörper 18 als Anschlußstellen 22 für die zum Rückwandisolierkörper 18 benachbart angeordneten weiteren Isolierkörper 17, 19 und 20 dienen. Die netzartig angelegten Kanäle 21 am Rückwandisolierkörper 18 sind in einer als Vorhof 23 ausgebildeten, ringähnlich angelegten Sammelstelle zusammengeführt, in deren Zentrum ein an der Außenseite des Rückwandabschnittes des Metallaußenmantels 12 vorgesehenen Evakuierstutzen 24 mündet, welcher als zentrale Anschlußstelle für eine nicht gezeigte Evakuierpumpe zur Evakuierung des Zwischenraumes 15 dient. Gegenüber des mit dem Evakuierstutzen 24 versehenen Rückwandabschnittes des wärmeisolierenden Gehäuses 11 ist dieses mit einer daran angeschlagenen ebenso wärmeisolierend ausgebildeten, über eine umlaufend angeordnete Magnetdichtung 25 am Gehäuserand elastisch aufliegenden Tür 26 versehen. Diese ist wie das wärmeisolierende Gehäuse 11 aus einem dünnwandigen metallischen Hüllmantel 27 (z.B. Edelstahl) gebildet, welcher hermetisch einen Zwischenraum 28 umschließt, welcher mit zur Wärmeisolation der Tür 26 dienenden plattenförmigen Isolationsmaterial 29 auf der Basis des zur Wärmeisolierung des Gehäuses 11 dienenden Wärmeisolationsmaterial 16 vollständig ausgefüllt ist. Das plattenförmige Wärmeisolationsmaterial 29 zur Wärmeisolierung der Tür 26 ist wie die beim warmeisolierenden Gehäuse 11 zur Anwendung kommenden Isolierkörper mit durch spanabhebende Formgebung eingebrachte Kanäle 30 flächendeckend netzartig überzogen, welche wie die am Rückwandisolierkörper 18 vorgesehenen Kanäle 21 in einer nicht dargestellten Sammelstelle zusammengeführt und strömungstechnisch mit einem nicht gezeigten Evakuierstutzen verbunden sind.As can be seen in particular from FIG. 2, the channels 21 are at approximately the same intervals arranged over the entire area of the insulating bodies 17 to 20 and over the rear wall insulating body 18 connected to a coherent channel system. To this end are the channels 21 on the rear wall insulating body 18 laid out like a net, the free ends of the network-like channels 21 on the rear wall insulating body 18 as connection points 22 for the further insulating bodies 17, 19 arranged adjacent to the rear wall insulating body 18 and 20 serve. The network-like channels 21 on the rear wall insulating body 18 are shown in FIG brought together in a ring-like collection point designed as atrium 23, in the center of which is on the outside of the rear wall section of the metal outer jacket 12 provided evacuation nozzle 24, which acts as a central connection point for a Evacuation pump, not shown, serves to evacuate the space 15. Across from of the rear wall section provided with the evacuation nozzle 24 of the heat-insulating Housing 11 is also heat-insulating with a struck on it trained, a circumferentially arranged magnetic seal 25 on the housing edge provided resilient door 26. This is like the heat-insulating housing 11 formed from a thin-walled metallic envelope 27 (e.g. stainless steel), which hermetically encloses an intermediate space 28, which also provides thermal insulation for the door 26 Serving plate-shaped insulation material 29 based on the for the thermal insulation of the Housing 11 serving heat insulation material 16 is completely filled. The plate-shaped heat insulation material 29 for heat insulation of the door 26 is like that at heat-insulating housing 11 to be used with insulator Machining shape, introduced channels 30 covered in a net-like manner, which like the channels 21 provided on the rear wall insulating body 18 are not in one shown collection point merged and fluidically with a not shown Evacuation nozzle are connected.

Anstatt der aus offenzelligen Hartschäumen gebildeten Plattenkörper zur Wärmeisolation des Gehäuses 11 können auch Glasfasermatten zum Einsatz kommen, welche wie die geschäumten Plattenkörper mit Kanälen versehen sind, deren Anordnung und Ausgestaltung denen der plattenförmigen Isolierkörper entspricht.Instead of the panel body made of open-cell rigid foams for thermal insulation the housing 11 can also be used glass fiber mats, which like the foamed Plate bodies are provided with channels, their arrangement and design that of the plate-shaped insulating body corresponds.

Alternativ zu dem beschriebenen Ausführungsbeispiel ist es auch möglich, daß zur Wärmeisolierung des Gehäuses 11 anstatt der plattenförmigen Isolationsmaterialien wärmeisolierendes, während des Verfüllvorganges des Zwischenraumes 15 bzw. 28 ständig zu verdichtendes Schüttgut wie Kieselgur oder Aerogele zum Einsatz kommen, wobei letztere eine Dichte von 80 bis 120 kg/m3 und eine Oberfläche von 7 x 105 m2/kg aufweisen sollen. Um auch bei dieser Art von Wärmeisolationsmaterial eine deutliche Reduzierung der Evakuierzeit zu erreichen, ist vorgesehen, in dieses Schüttgut Kanäle einzubetten, welche wie unter Fig. 3 gezeigt ist als Rohrleitungen 35 ausgebildet sind, welche wie die Kanäle 21 an der Decke, am Boden und an den beiden Seitenwänden des wärmeisolierenden Gehäuses in einer Richtung verlaufen, während sie an der Rückwand des wärmeisolierenden Gehäuses 11 und an der Tür 26 netzartig flächendeckend angelegt sind. Die Rohrleitungen 35 sind wie die Kanäle 21 in einer Sammelstelle zusammengeführt und im Bereich der Gehäuserückwand zur Erzeugung des netzartigen Aufbaues aus kurzen miteinander verbundenen Rohrabschnitten gebildet. Die Rohrleitungen 35 sind zum Zweck des verbesserten Luftdurchsatzes an ihrer Rohrwandung 36 mit annähernd gleichmäßig über ihren Wandungsumfang und über ihre Wandungslänge angeordneten Durchbrüchen 37 versehen. Die Rohrleitungen 35 in den einzelnen Gehäusewandabschnitten des wärmeisolierenden Gehäuses 11 sind an ihrer Schnittstelle zu den in der Rückwand des Gehäuses 11 vorgesehenen netzartigen Rohrleitungsanordnung mit elastischen oder entsprechend geformten Verbindungselementen zu einem zusammenhängenden Kanal- oder Rohrleitungssystem verbunden, welches zentral über einen in der Sammelstelle mündenden Evakuierstutzen absaugbar ist. Die Durchbrüche 37 in den Rohrwandungen 36 sind dabei so bemessen, daß deren Querschnitt geringer als der Querschnitt des Schüttgutes ist. Für die Rohrleitungen 35 ist es vorstellbar, daß diese als vorgefertigte Einheiten aus verschiedenen Metallen oder aus mit geringer Diffusion ausgestatteten Kunststoffen hergestellt sind und vor dem Verfüllen des Gehäuses 11 bzw. der Tür 26 mit dem als Schüttgut ausgebildeten Wärmeisolationsmaterial in den Zwischenraum 15 bzw. 28 eingelegt und dann evakuierzeitoptimiert positioniert sind. Ferner ist es denkbar, daß zum Ausgleich von Diffusionsvorgängen innerhalb der Zwischenräume 15 bzw. 28 Getterwerkstoffe zum Ausgleich der Diffusionsvorgänge eingelegt sind.As an alternative to the exemplary embodiment described, it is also possible that, for the thermal insulation of the housing 11, instead of the plate-shaped insulation materials, heat-insulating bulk material, such as diatomaceous earth or aerogels, to be compressed during the filling process of the intermediate space 15 or 28 is used, the latter having a density of 80 to 120 kg / m 3 and a surface area of 7 x 10 5 m 2 / kg. In order to achieve a significant reduction in the evacuation time even with this type of heat insulation material, provision is made for embedding channels in this bulk material, which, as shown under FIG. 3, are designed as pipelines 35 which, like the channels 21, on the ceiling, on the floor and on the two side walls of the heat-insulating housing run in one direction, while they are applied to the rear wall of the heat-insulating housing 11 and on the door 26 in a net-like manner. The pipes 35, like the channels 21, are brought together in a collection point and are formed in the region of the rear wall of the housing to produce the network-like structure from short pipe sections connected to one another. For the purpose of improved air throughput, the pipes 35 are provided on their pipe wall 36 with openings 37 arranged approximately uniformly over their wall circumference and over their wall length. The pipes 35 in the individual housing wall sections of the heat-insulating housing 11 are connected at their interface to the network-like piping arrangement provided in the rear wall of the housing 11 with elastic or correspondingly shaped connecting elements to form a coherent duct or piping system, which is connected centrally via an evacuation connection opening into the collection point is extractable. The openings 37 in the tube walls 36 are dimensioned such that their cross section is less than the cross section of the bulk material. For the pipelines 35, it is conceivable that they are manufactured as prefabricated units from different metals or from plastics with little diffusion and before the housing 11 or the door 26 is filled with the thermal insulation material designed as bulk material into the intermediate space 15 or 28 inserted and then positioned to optimize evacuation time. Furthermore, it is conceivable that to compensate for diffusion processes 15 or 28 getter materials are inserted to compensate for the diffusion processes.
