Description

Die Erfindung betrifft ein Kühlgerät gemäß dem Oberbegriff des ersten Anspruchs.The invention relates to a cooling device according to the preamble of the first claim.

Bei einem bekannten Kühlgerät dieser Art (US 2 000 882) ist der eigentliche Kühlbehälter wie eine dessen Zugrifföffnung verschließende Tür jeweils aus einer glattwandigen Innenschale und einer mit Abstand davon angeordneten. Außenschale aufgebaut, die aus Metallblechen bestehen und an ihren Randzonen vakuumdicht über schlecht wärmeleitende Verbindungselemente abgeschlossen sind. Zwischen den Innen- und Außenschalen befindet sich jeweils ein schlecht wärmeleitendes Wärmeisoliermaterial als Stützmittel gegen den auf die Wandflächen wirkenden Luftdruck.In a known cooling device of this type (US Pat. No. 2,000,882), the actual cooling container, like a door closing its access opening, is in each case composed of a smooth-walled inner shell and one spaced apart therefrom. Built outer shell, which consist of metal sheets and are vacuum-sealed at their edge zones via poorly heat-conducting connecting elements. Between the inner and outer shells there is a poorly heat-conducting thermal insulation material as a support against the air pressure acting on the wall surfaces.

Der Erfindung liegt die Aufgabe zugrunde, bei einem Kühlgerät gemäß dem Oberbegriff des ersten Anspruchs Maßnahmen zu treffen, durch die auf einfache Weise Funktionselemente in dem von den glatten Innenwänden umschlossenen Kühlraum angeordnet werden können.The invention has for its object to take measures in a cooling device according to the preamble of the first claim, through which functional elements can be arranged in a simple manner in the cooling space enclosed by the smooth inner walls.

Die Lösung dieser Aufgabe erfolgt gemäß der Erfindung durch die kennzeichnenden Merkmale des ersten Anspruchs.This object is achieved according to the invention by the characterizing features of the first claim.

Bei einem Aufbau eines Kühlgeräts gemäß der Erfindung wird in den Kühlraum ein eigenständiges, als geschlossenes Flächenelement ausgebildetes Tragelement eingebracht, das sich auf zumindest weitgehend waagerechten Abschnitten der den Kühlraum begrenzenden Wände abstützt. Das ist in dem den eigentlichen Kühlraum umschließenden Kühlbehälter die Bodenwand oder eine stufig abgesetzte Rückwand, wobei auch gegenüberliegende senkrechte Seitonwände vorzugsweise im unteren Bereich mit entsprechenden Stufenabsätzen versehen sein können, auf welchen sich das Tragelement abstützen kann. Auch die Türinnenwand kann mit einem entsprechenden Stufenabsatz versehen sein, es kann jedoch auch der obere waagerechte, nach außen gerichtete Seitenrand als Auflage für das vor die Türinnenwand greifende Tragelement dienen. Vorzugsweise ist jedoch um dem umlaufenden Türaußenrand ein Wärmedämmprofil gelegt, das mit einem Steg in den Kühlraum übersteht, an welchem das Tragelement ggf. zusätzlich gehalten werden kann. Das Tragelement ist dabei insbesondere als die Türinnenwand überdeckende und den Türaußenrand übergreifende Türinnenhaube ausgebildet, die nachträglich auf die Türinnenseite aufgesetzt wird und Halteelemente für Türabstellfächer und dergl. aufweist.In the construction of a cooling device according to the invention, an independent support element designed as a closed surface element is introduced into the cooling space is supported on at least largely horizontal sections of the walls delimiting the cooling space. In the cooling container that surrounds the actual cooling space, this is the bottom wall or a stepped rear wall, whereby opposite vertical side walls can also preferably be provided in the lower area with corresponding step heels on which the supporting element can be supported. The inside wall of the door can also be provided with a corresponding step, but the upper horizontal, outward-facing side edge can also serve as a support for the support element which reaches into the inside wall of the door. However, a thermal insulation profile is preferably placed around the circumferential outer edge of the door, which protrudes with a web into the cooling space, on which the supporting element can optionally also be held. The support element is designed in particular as a door inner hood covering the inner door wall and overlapping the outer door edge, which is subsequently placed on the inner side of the door and has holding elements for door storage compartments and the like.

Das in den Kühlbehälter einzusetzende Tragelement ist insbesondere in der Form eines üblichen Kunststoffinnenbehälters ausgebildet, wie er für Kühlgeräte mit Schaumisolierung zur Anwendung gelangt. Dieser Innenbehälter ist vorzugsweise der Innenkontur des Kühlbehälters angepaßt und besteht aus tiefgezogenem oder gespritztem Kunststoff mit den notwendigen waagerechten Führungsleisten für einzuschiebende Kühlgutablageplatten, Halteelemente für Regel- und Beleuchtungseinrichtungen, wobei insbesondere an seiner Rückseite für einen Verdampfer entsprechende Halteelemente vorgesehen sein können. Der Verdampfer kann dabei zwischen der Rückseite des Innenbehälters und der Rückseite des Kühlbehälters vorgesehen werden, wenn seine Anordnung im Inneren des Innenbehälters nicht erwünscht ist. Am Innenbehälter können auch von außen nach innen eingeformte Nuten vorgesehen sein, in welchen elektrische Leitungen oder beispielsweise Kapillarrohrleitungen eines hydraulischen Thermostaten verlegt werden können. Auch andere, für den Betrieb zweckmäßige Funktionselemente können an diesem Innenbehälter befestigt sein. Dieser Innenbehälter kann unmittelbar auf die Bodenwand des Kühlbehälters aufgestellt werden. Es ist jedoch auch möglich, ihn auf Stufenabsätze der senkrechten Seitanwände aufzusetzen, wenn zwischen der Unterseite das Innenbehälters und der Bodenwand des Kühlbehälters ein freier Raum für beispielsweise Gemüse-, Obst- oder Fleischschalen verbleiben soll. Der Innenbehälter kann dann mit entsprechen vermindertem Materialaufwand ausgebildet werden. Der Boden des Innenbehälters dient dann als zusätzliche Ablagefläche, wobei bei einer Verkürzung des Innenbehälters in der Höhe auch seine Oberseite als Ablagefachboden verwendet werden kann.The support element to be inserted into the cooling container is in particular in the form of a conventional plastic inner container as used for cooling devices with foam insulation. This inner container is preferably adapted to the inner contour of the cooling container and consists of thermoformed or injection-molded plastic with the necessary horizontal guide strips for cooling goods storage plates to be inserted, holding elements for control and lighting devices, and in particular on the rear side corresponding holding elements can be provided for an evaporator. The evaporator can be provided between the rear of the inner container and the rear of the cooling container if it is not desired to arrange it inside the inner container. Grooves formed from the outside in can also be provided on the inner container be in which electrical lines or, for example, capillary tubes of a hydraulic thermostat can be laid. Other functional elements suitable for operation can also be attached to this inner container. This inner container can be placed directly on the bottom wall of the cooling container. However, it is also possible to place it on step heels of the vertical side walls if a free space for, for example, vegetable, fruit or meat dishes is to remain between the underside of the inner container and the bottom wall of the cooling container. The inner container can then be formed with a correspondingly reduced amount of material. The bottom of the inner container then serves as an additional storage surface, and if the height of the inner container is reduced, its top can also be used as a storage compartment.

Der Innenbehälter wird vorzugsweise mit einem radial nach außen abgewinkelten Behälterrand ausgestattet, der einen die Zugrifföffnung umschließenden Kühlbehälterrand übergreift. Dieser Behälterrand bestimmt die Einschubtiefe und bildet einen stirnseitigen Abschluß der Isolierwände des Innenbehälters und schützt zugleich mechanisch dünne Abschlußfolien, die einen übermäßigen Wärmeübergang von den gekühlten Innenwänden zu den Außenwänden bei vakuumdichtem Abschluß vermeiden. Der Behälterrand kann dabei gleichzeitig für die zwischen dem Kühlbehälter und der Tür erforderliche Dichtung ausgenutzt werden, wobei es zweckmäßig ist, auf dem Behälterrand einen magnetisierbaren Blechstreifen als magnetischen Gegenpol für eine der Tür zugeordnete Magnetprofildichtung anzubringen.The inner container is preferably equipped with a container edge which is angled radially outwards and which overlaps a cooling container edge which surrounds the access opening. This edge of the container determines the depth of insertion and forms a front end of the insulating walls of the inner container and at the same time protects mechanically thin end foils which prevent excessive heat transfer from the cooled inner walls to the outer walls with a vacuum-tight end. The edge of the container can simultaneously be used for the seal required between the cooling container and the door, it being expedient to attach a magnetizable sheet metal strip on the edge of the container as a magnetic opposite pole for a magnetic profile seal assigned to the door.

Auch die auf die Türinnenwand aufgesetzte Türinnenhaube wird als Tragelement vorzugsweise bis in den Bereich der Türaußenkante hinausgezogen und trägt dort die umlaufende Magnetprofildichtung. Die Innenwände des Kühlbehälters wie der Tür brauchen somit insgesamt keine besonders daran anzubringenden oder auszuformenden Halteelemente aufzuweisen. Das ist besonders dann von Vorteil, wenn die Innenflächen und Außenflächen der wärmeisolierten Wände aus Gründen der Gasdiffusionsdichtheit aus Edelstahl bestehen, der nur schwer tiefziehbar ist und im übrigen das Anbringen von Halteelementen nur durch Schweißen zuläßt, um die notwendige Gasdichtheit nicht zu vermindern.The inner door hood placed on the inner wall of the door is also preferably pulled out as a supporting element into the area of the outer edge of the door and carries the circumferential one there Magnetic profile seal. The inner walls of the cooling container, such as the door, therefore do not need to have any holding elements to be attached or molded. This is particularly advantageous if, for reasons of gas diffusion tightness, the inner and outer surfaces of the heat-insulated walls are made of stainless steel, which is difficult to deep-draw and, moreover, only allows holding elements to be attached by welding, in order not to reduce the necessary gas tightness.

Zweckmäßig ist es, den Türhaubenaußenrand stufig abzusetzen, wobei diese Stufe eine entsprechende zur Türaußenschale hin abfallende Türkantenstufe der Türinnenwand rundumlaufend übergreift. Die Türhaube ist dann auf der umlaufenden Türkantenstufe zentriert und gegen Abrutschen nach unten gehalten. Dabei ist es sinnvoll, zwischen den Türaußenrand und den Türhaubenaußenrand ein Wärmedämmprofil einzulegen, das die Verbindungsfolie zwischen Außen- und Innenwand schützt. Dieses Wärmedämmprofil kann zugleich als in sich geschlossener Rahmen ausgebildet sein, der am Türaußenrand festgesetzt ist und die Türinnenhaube trägt. Dabei kann es zweckmäßig sein, am Wärmedämmprofil einen die Türinnenwand in den Kühlraum hinein überragenden Steg anzuformen, der in eine angepaßte Ausformung der Türinnenhaube eingreift, so daß insbesondere an den senkrechten Ausformungen der Türinnenhaube Halteelemente für Türabsteller und dergl. ausgeformt werden können.It is expedient to step down the outer edge of the door hood, this step encompassing a corresponding edge of the door edge of the inner door wall falling towards the outer door shell. The door hood is then centered on the all-round door edge step and held down to prevent it from slipping down. It makes sense to insert a thermal insulation profile between the outer edge of the door and the outer edge of the hood, which protects the connecting film between the outer and inner wall. This thermal insulation profile can also be designed as a self-contained frame which is fixed on the outer edge of the door and carries the inner door hood. It may be expedient to form on the thermal insulation profile a web projecting beyond the door inner wall into the cooling space, which engages in an adapted shape of the door inner hood so that holding elements for door racks and the like can be formed in particular on the vertical shapes of the door inner hood.

Die Erfindung ist nachfolgend anhand der Prinzipdarstellungen eines Ausführungsbeispiels näher erläutert.The invention is explained in more detail below on the basis of the basic representations of an exemplary embodiment.

Ein Kühlgerät, das insbesondere als Kühl- und/oder Gefrierschrank oder Truhe ausgebildet ist, weist einen Kühlbehälter 1 auf, der einen das zu kühlende Gut aufnehmenden Kühlraum 2 umschließt und dessen von einem Kühlbehälterrand 3 umschlossene Zugrifföffnung mittels einer Tür 4 dicht verschließbar ist. Der Kühlbehälter 1 wie die Tür 4 weisen voll vakuumisolierte Wände auf, bei welchen im Hohlraum zwischen aus Edelstahlblech gefertigten Außenwänden 5 und Innenwänden 6 ein wärmedämmendes Stützmittel 7 aus einem Pulver oder aus Fasern angeordnet ist. Der Hohlraum ist zur Erzeugung einer hochwertigen Wärmeisolierung zumindest weitgehend evakuiert. Insbesondere die Innenwände 6 sind aus Fertigungsgründen glatt belassen und weisen nur soweit notwendig, durchgehende stufige Absetzungen auf, wie es beispielsweise bei der Rückwand 8 des Kühlraums 2 der Fall ist, um eine für die Unterbringung eines Kompressors oder anderer Bauteile erforderliche Nische 9 vorsehen zu können. Die Rückwand 8 ist daher nach Art einer in den Kühlraum 2 hineingezogenen Stufe 10 ausgeformt, die mit der dementsprechend verkürzten Bodenwand 11 verbunden ist.A cooling device, which is designed in particular as a refrigerator and / or freezer or chest, has a cooling container 1 which encloses a cooling space 2 which receives the goods to be cooled and whose access opening, which is surrounded by a cooling container edge 3, can be sealed by means of a door 4. The cooling container 1 and the door 4 have fully vacuum-insulated walls, in which a heat-insulating proppant 7 made of a powder or fibers is arranged in the cavity between the outer walls 5 made of stainless steel sheet and the inner walls 6. The cavity is at least largely evacuated to produce high quality thermal insulation. In particular, the inner walls 6 are left smooth for production reasons and only have continuous, step-by-step settlements, as is the case, for example, with the rear wall 8 of the cooling space 2, in order to be able to provide a niche 9 required for accommodating a compressor or other components . The rear wall 8 is therefore shaped in the manner of a step 10 drawn into the cooling space 2, which is connected to the correspondingly shortened bottom wall 11.

Um im Kühlraum 2 die für den Betrieb des Kühlgeräts erforderlichen Funktionselemente wie Ablageplatten, Regler, Verdampfer, Beleuchtung und dergl. unterbringen zu können, ohne die Innenwände 6 verformen oder mit zusätzlichen Haltemitteln versehen zu müssen, ist in den Kühlraum 2 ein eigenständiges Tragelement in Form eines Innenbehälters 12 durch die Zugrifföffnung eingeschoben, der sich insbesondere auf der Bodenwand 11 und den waagerechten Abschnitt der Stufe 10 abstützt. Der Innenbehälter 12 weist geschlossene Flächenelemente auf und ist insbesondere im Kunststofftiefziehverfahren aus einer Platine gezogen oder im Spritzverfahren hergestellt. Dieser Innenbehälter 12 kann mit allen notwendigen Halteelementen wie waagerechten Führungsleisten 13 für einzuschiebende Ablageplatten in senkrechten, sich gegenüberstehenden Seitenwänden 14, eine Nut 15 zur Führung eines elektrischen Kabels 16 für eine im Innenbehälter 12 anzubringende Beleuchtungseinrichtung und ein Kapillarrohr 17 für ein ebenfalls in Innenbehälter 12 vorgesehenen Temperaturregler aufnehmen. Der Innenbehälter 12 ist vorzugsweise so ausgebildet, daß seine Seitenwände 14 dicht an den benachbarten Innenwänden 6 anliegen und sein Boden 18 mit der der Stufe 10 angepaßten Stufe 19 auf der Bodenwand 11 bzw. der Stufe 10 aufruht. Auch die Deckenwand 20 des Innenbehälters 12 kann dicht an die betreffende Deckenwand im Kühlraum 2 angelegt sein. Zwischen der Rückwand 21 des Innenbehälters 12 und der benachbarten Rückwand 8 des Kühlgutbehälters 1 ist ein Spalt belassen, in dem ein Verdampfer 22, vorzugsweise ein Plattenverdampfer angeordnet wird. Auch der Verdampfer 22 ist an Halteelementen festgesetzt, die an den Innenbehälter 12 angeformt sind. Der Verdampfer 22 kann jedoch auch innerhalb des Innenbehälters auf der Rückwand 21 festgesetzt werden.In order to be able to accommodate the functional elements required for the operation of the cooling device, such as storage plates, controllers, evaporators, lighting and the like, in the cooling room 2, Without deforming the inner walls 6 or having to provide additional holding means, an independent support element in the form of an inner container 12 is inserted into the cooling space 2 through the access opening, which is supported in particular on the bottom wall 11 and the horizontal section of the step 10. The inner container 12 has closed surface elements and is drawn from a board, in particular in the plastic deep-drawing process, or is produced in the injection molding process. This inner container 12 can be provided with all the necessary holding elements such as horizontal guide strips 13 for storage shelves to be inserted in vertical, opposing side walls 14, a groove 15 for guiding an electrical cable 16 for a lighting device to be fitted in the inner container 12 and a capillary tube 17 for a likewise provided in the inner container 12 Record temperature controller. The inner container 12 is preferably designed so that its side walls 14 lie closely against the adjacent inner walls 6 and its bottom 18 rests on the bottom wall 11 or the step 10 with the step 19 adapted to the step 10. The top wall 20 of the inner container 12 can also be placed close to the top wall in question in the cooling room 2. A gap is left between the rear wall 21 of the inner container 12 and the adjacent rear wall 8 of the refrigerated goods container 1 in which an evaporator 22, preferably a plate evaporator, is arranged. The evaporator 22 is also fixed to holding elements which are molded onto the inner container 12. However, the evaporator 22 can also be fixed on the rear wall 21 within the inner container.

Der Innenbehälter 12 ist mit einem radial nach außen abgewinkelten, umlaufenden Behälterrand 23 versehen, der den Kühlbehälterrand 3 rundum übergreift. Dieser Behälterrand 23 begrenzt zum einen die Einschubtiefe des Innenbehälters 12 in den Kühlraum 2 und bildet einen Teil einer Dichtungsanordnung zwischen der Tür 4 und dem Kühlgutbehälter 1. Hierzu ist der Behälterrand 23 mit einem magnetisierbaren, insbesondere aus Stahlblech gebildeten Streifen 24 als magnetischen Gegenpol für eine der Tür 4 zugeordnete Magnetprofildichtung 25 versehen. Dabei überdeckt der Behälterrand 23 die Zone im Bereich des Kühlbehälterrandes 3, in welcher die Innenwand mit der Außenwand durch eine vakuumdicht ausgebildete und angesetzte Dichtmembran 26 verbunden ist. Zum Schutz dieser Dichtmembran 26 gegen mechanische Beschädigung beim Aufbau des Kühlgeräts ist es zweckmäßig, diese Dichtmembran 26 nach außen mit einen stabilen Abdeckstreifen 27 gegen Beschädigung zu schützen.The inner container 12 is provided with a radially outwardly angled, circumferential container edge 23 which engages over the cooling container edge 3 all around. This container edge 23 limits the insertion depth of the inner container 12 into the cooling space 2 and forms part a sealing arrangement between the door 4 and the refrigerated goods container 1. For this purpose, the container rim 23 is provided with a magnetizable strip 24, in particular made of sheet steel, as a magnetic counter-pole for a magnetic profile seal 25 assigned to the door 4. The container rim 23 covers the zone in the region of the cooling container rim 3, in which the inner wall is connected to the outer wall by a sealing membrane 26 which is designed to be vacuum-tight and attached. To protect this sealing membrane 26 against mechanical damage during the construction of the cooling device, it is expedient to protect this sealing membrane 26 from the outside with a stable cover strip 27 against damage.

Bei der Tür 4 ist das verwendete vakuumisolierte Wandelement mit einer Innenwand 6 versehen, die kleiner als die Außenwand 5 ist, wobei die dort zur Anwendung gelangende Dichtmembran 28 zwischen den beiden Wänden 5,6 rundum stufig ausgebildet ist, um die Wirkung der Vakuumisolation optimal nutzen zu können. Zum Schutz der stufig ausgebildeten Dichtmembran 28 ist ein dieser Stufenform angepaßtes Wärmedämmprofil 29 vorgesehen, das insbesondere als geschlossener Rahmen ausgebildet ist und rundum die Dichtungsmembran 28 abdeckt. Das Wärmedämmprofil 29 besitzt zusätzlich einen in den Kühlraum ragenden Steg 30, der ebenfalls umläuft und an einem ebenfalls in den Kühlraum 2 hin abgewinkelten Rand 31 der Türinnenwand 6 festgesetzt ist. Das Wärmedämmprofil 29 reicht zudem bis an den Türaußenrand 32, der als abgewinkelter Rand des Türaußenblechs 5 ausgebildet ist und einer Flucht mit der angrenzenden Behälteraußenwand 5 liegt.In the case of the door 4, the vacuum-insulated wall element used is provided with an inner wall 6 which is smaller than the outer wall 5, the sealing membrane 28 used there being stepped all around between the two walls 5, 6 in order to optimally use the effect of the vacuum insulation to be able to. To protect the step-shaped sealing membrane 28, a heat-insulating profile 29 which is adapted to this step shape is provided, which is designed in particular as a closed frame and covers the sealing membrane 28 all around. The thermal insulation profile 29 additionally has a web 30 projecting into the cooling space, which also rotates and is fixed to an edge 31 of the inner door wall 6 which is also angled into the cooling space 2. The thermal insulation profile 29 also extends to the outer edge 32 of the door, which is designed as an angled edge of the outer door panel 5 and is flush with the adjacent outer wall 5 of the container.

Auf die Türinnenwand 6 ist eine Türinnenhaube 33 aufgesetzt, die ebenfalls aus einer Kunststoffplatine gezogen oder im Kunststoffspritzverfahren hergestellt sein kann und der durch das Wärmedämmprofil 29 mit Steg 30 vorgegebenen Kontur folgt und radial bis in den Bereich der Türaußenkante 32 reicht. Dabei weist die Türinnenschale 33 im Randbereich eine dem Steg 30 angepaßte umlaufende Ausformung 34 auf. Der Steg 30 wirkt so als Halteelement für die Türinnenschale 33, die zudem in gleicher Weise stufig wie das Wärmedämmprofil 29 bzw. die Dichtmembran 28 abgesetzt ist und so mit ihrem stufig abgesetzten Türhaubenaußenrand 35 die zur Türaußenwand 5 hin abfallende, am Wärmedämmprofil 29 ausgebildete Türkantenstufe 36 übergreift. Die Türinnenhaube 33 ist so am Steg 30 bzw. an der Türkantenstufe 36 zentriert, wobei die waagerechten Partien des Steges 30 bzw. der oberen Türkantenstufe 36 die an der Türhaube 33 auftretenden Gewichtskräfte auffangen. Im Bereich des Türhaubenaußenrandes 35 befindet sich die Magnetprofildichtung 25, die mit dem magnetisierbaren Streifen 24 am Behälterrand 23 bei geschlossener Tür 4 zusammenwirkt. Das zwischen den Türaußenrand 32 und den Türhaubenaußenrand 35 eingefügte Wärmedämmprofil 29 bildet als umlaufender geschlossener einstückiger Rahmen eine einfache Möglichkeit zur Befestigung der Türinnenhaube 33.A door inner hood 33 is placed on the inner door wall 6, which can also be drawn from a plastic board or can be produced by the plastic injection molding process and which has a web 30 through the thermal insulation profile 29 follows predetermined contour and extends radially into the area of the outer door edge 32. In this case, the inner door shell 33 has a circumferential shape 34 adapted to the web 30 in the edge region. The web 30 thus acts as a holding element for the inner door shell 33, which is also stepped in the same way as the thermal insulation profile 29 or the sealing membrane 28 and thus, with its stepped outer hood edge 35, the door edge step 36 formed on the thermal insulation profile 29 and falling towards the outer door wall 5 spreads. The inner door hood 33 is thus centered on the web 30 or on the door edge step 36, the horizontal parts of the web 30 or the upper door edge step 36 absorbing the weight forces occurring on the door hood 33. In the area of the outer edge of the door hood 35 there is the magnetic profile seal 25 which interacts with the magnetizable strip 24 on the container edge 23 when the door 4 is closed. The thermal insulation profile 29 inserted between the outer edge 32 of the door and the outer edge 35 of the door hood, as a continuous closed one-piece frame, forms a simple possibility for fastening the inner door hood 33.

Die vom Steg 30 hintergriffene Ausformung 34 ist mit Halteelementen 37 im Bereich von senkrechten Abschnitten der Ausformung 34 versehen. An solchen Halteelementen 37 können Türabsteller oder dergl. festgesetzt werden. An den waagerechten, nach Art von Leisten ausgebildeten Teilen der Ausformung 34, die einen rundum geschlossenen Halterahmen bilden, ist die Türinnenhaube 33 zusätzlich abgestützt.The formation 34 which is engaged by the web 30 is provided with holding elements 37 in the region of vertical sections of the formation 34. Door racks or the like can be attached to such holding elements 37. The inner door cover 33 is additionally supported on the horizontal parts of the formation 34 which are designed in the manner of strips and which form an all-round closed holding frame.

Bei dieser Ausgestaltung kann somit die Innenausstattung für Funktionsteile, wie Verdampfer, Ablageplatten, Beleuchtung oder Regler und dergl. ohne Eingriff in die vakuumisolierten Wandungen aufgebaut werden. Dabei lassen sich die nachträglich eingesetzten Tragelemente 12,33 mit gerundeten Kanten ergonomisch günstig und leicht reinigbar ausbilden.With this configuration, the interior for functional parts, such as evaporators, storage plates, lighting or regulators and the like, can thus be constructed without any intervention in the vacuum-insulated walls. The support elements 12, 33 used subsequently can also be used Form rounded edges ergonomically and easily cleanable.
