Abstract

In a refrigerator, corresponding support paths (5) are provided on opposite side walls (4) of an internal container (3), on which paths opposite side edge sections of a shelving plate (6) rest. In this case, set-back edge sections (7.1) are formed free of support elements projecting towards the neighbouring support path (5), support path sections (5.1) being provided, which are drawn so far towards the centre of the internal container that they reach under set-back edge sections (7.1). <IMAGE>

Description

Die Erfindung betrifft ein Kühlgerät gemäß Oberbegriff des Anspruchs 1.The invention relates to a cooling device according to the preamble of claim 1.

Für ein bekanntes Kühlgerät dieser Art ist eine Abstellplatte vorgesehen (DE 39 35 212 A1), die bei im wesentlichen rechteckiger Grundform an gegenüberliegenden Seitenrändern Ausklinkungen aufweist, wobei der in der Betriebslage vorn liegende Teil des Seitenrandes bestehen bleibt und lediglich zur hinteren Rückkante hin die Ausklinkungen vorgesehen sind. Als Auflageelemente befinden sich jedoch nahe der Rückkante auskragende Auflageelemente, durch welche die Breite der Abstellplatte in diesem Bereich wieder auf die Ursprungsbreite der vorn liegenden, unveränderten Randabschnitte verbreitert ist. Diese Auflageelemente greifen wie die vorn liegenden unveränderten Randabschnitte in dem Kühlgerät auf Auflagebahnen, die insbesondere durch Nuten gebildet sind, die in sich gegenüber stehenden senkrechten Seitenwänden des das zu kühlende Gut aufnehmenden Innenbehälters vorgesehen sind. Die durch die Ausklinkungen gebildeten, zur Mitte der Abstellplatte hin zurückgesetzten Randabschnitte sind soweit nach innen versetzt, daß ihr gegenseitiger Abstand kleiner als der Abstand zwischen den Auflagebahnen ist. Die Auflagebahnen enden dabei zu der durch eine Tür zu verschließenden Üffnung des Innenbehälters hin mit Abstand. Dabei ist die Länge der unveränderten Randabschnitte der Seitenkanten jedenfalls kürzer als der Abstand zwischen den freien Enden der betreffenden Auflagebahnen und der geöffneten Gerätetür bzw. deren Einbauten. Hierdurch kann die Abstellplatte zur Tür hin so weit vorgezogen werden, daß die unveränderten Randabschnitte von den betreffenden Auflagebahnen heruntergleiten. Die Auflageplatte ist dann für eine Schwenkung nach unten oder oben frei, wobei dann jedoch noch die im hinteren Bereich vorgesehenen Auflageelemente der Abstellplatte auf den Auflagebahnen bzw. in den Führungsnuten verbleiben. Durch Ab- oder Aufschwenken der Abstellplatte können jedoch die Auflageelemente ebenfalls nach vorn bewegt werden, bis sie schließlich wie die unveränderten Seitenrandabschnitte außer Eingriff mit den Auflagebahnen gelangen. Dann kann die Abstellplatte ungehindert aus dem Kühlraum entnommen werden. Bei dieser Ausgestaltung bilden die im hinteren Bereich der Abstellplatte vorgesehenen Auflageelemente aufgrund ihrer notwendigerweise geringen Querschnitte am Übergang zur Abstellplatte eine bruchgefährdete Stelle und üben zudem eine relativ hohe Flächenpressung auf die Auflagebahnen aus. Die Bruchgefahr ist dabei besonders groß, wenn die Abstellplatte insgesamt aus Glas besteht. Dabei ist die Herstellung von Ausklinkungen zur Erzeugung der zurückgesetzten Randabschnitte arbeitsaufwendig und führt im Herstellungsprozeß zu erheblichem Ausschuß. Zudem müssen diese Auflageelemente niedrig ausgebildet werden, wenn der Höhenabstand zwischen benachbarten Auflagebahnen gering sein soll.For a known cooling device of this type, a storage plate is provided (DE 39 35 212 A1), which has notches in an essentially rectangular basic shape on opposite side edges, the part of the side edge lying in front in the operating position remaining and the notches only towards the rear rear edge are provided. However, as support elements there are cantilevered support elements near the rear edge, by means of which the width of the storage plate in this area is widened again to the original width of the unchanged edge sections lying in front. These support elements, like the front unchanged edge sections in the cooling device, grip support tracks which are formed in particular by grooves which are provided in mutually opposing vertical side walls of the inner container which holds the material to be cooled. The edge sections formed by the notches and set back towards the center of the storage plate are offset so far inward that their mutual distance is smaller than the distance between the support tracks. The support tracks end at a distance from the opening of the inner container to be closed by a door. The length of the unchanged edge sections of the side edges is in any case shorter than the distance between the free ends of the respective support tracks and the opened appliance door or its internals. As a result, the storage plate can be pulled towards the door so far that the unchanged edge sections slide off the relevant support tracks. The support plate is then free for pivoting downwards or upwards, but then the support elements of the storage plate provided in the rear area on the support tracks or remain in the guide grooves. However, the support elements can also be moved forward by swiveling the support plate off or on until finally, like the unchanged side edge sections, they disengage from the support tracks. Then the shelf can be removed from the cold room unhindered. In this embodiment, the support elements provided in the rear area of the storage plate form a point at risk of breakage due to their necessarily small cross sections at the transition to the storage plate and also exert a relatively high surface pressure on the support tracks. The risk of breakage is particularly great if the shelf is made entirely of glass. The production of notches for producing the recessed edge sections is labor-intensive and leads to considerable rejects in the production process. In addition, these support elements must be made low if the height distance between adjacent support tracks is to be small.

Der Erfindung liegt die Aufgabe zugrunde, ein Kühlgerät gemäß dem Oberbegriff des Anspruchs 1 zu schaffen, bei dem die Kontur der Seitenränder der Abstellplatte vereinfacht werden kann.The invention has for its object to provide a cooling device according to the preamble of claim 1, in which the contour of the side edges of the storage plate can be simplified.

Die Lösung dieser Aufgabe erfolgt gemäß der Erfindung durch die kennzeichnenden Merkmale des Anspruchs 1.This object is achieved according to the invention by the characterizing features of claim 1.

Bei einer Ausgestaltung des Kühlgeräts gemäß der Erfindung können die zurückgesetzten Randabschnitte der Abstellplatte stufenlos bis zu der parallel zur Rückwand des Innenbehälters laufenden Rückkante der Abstellplatte verlaufen, wobei die Unterstützung der Abstellplatte im hinteren Bereich durch an den Seitenwänden des Innenbehälters vorgesehene Auflagebahnabschnitte erfolgt, die gegenüber den Auflagebahnabschnitten, welche mit den unveränderten vorderen Randabschnitten der Abstellplatte zusammenwirken, entsprechend weiter in den Innenraum des Innenbehälters ragen. Auch diese Auflagebahnabschnitte sind dabei vorzugsweise Teil einer entsprechend ausgebildeten U-förmigen Führungnut für die Abstellplatte. Da die zurückgesetzten Randabschnitte demnach frei von zur benachbarten Auflagebahn auskragenden Auflageelementen sind, können sich die Ausklinkungen von den vorderen unveränderten Randabschnitten stufenlos bis zur hinteren Rückkante der Abstellplatte erstrecken. Derart geradlinige Konturen sind jedoch nicht nur in Kunststoff- oder Metallausführung sondern auch in Glasausführung der Abstellplatte leicht zu realisieren. Die vorzugsweise einstückig in die Seitenwände des Innenbehälters eingeformten und nur tiefer in den Innenraum ragenden Auflagebahnabschnitte für die zurückgesetzten Seitenrandabschnitte erfordern lediglich eine entsprechende Konfigurierung der Zieh- oder Spritzwerkzeuge für den aus Kunststoff gefertigten Innenbehälter. Bei vereinfachter Konturgestaltung bleiben damit die Möglichkeiten zum Entfernen der Abstellplatte voll erhalten. Hierbei kann bei den einstufig zurückgesetzten Randabschnitten der Überdeckungsbereich des zurückgesetzten Randabschnitts mit dem vorgezogenen Auflagebahnabschnitt in Einschubrichtung länger als der Überdeckungsbereich zwischen den übrigen Abschnitten der unveränderten Seitenränder und dazugehörigen Auflagebahnen ausgebildet werden. Der spezifische Auflagedruck der Abstellplatte wird hierdurch im rückwärtigen Bereich wesentlich gegenüber einer Zapfenlösung vermindert und es ist sichergestellt, daß zuerst die vorderen unveränderten Seitenrandabschnitte von den zugehörigen Auflagebahnen abgleiten, bevor die zurückgesetzten Seitenrandabschnitte von den zugehörigen Auflagebahnabschnitten heruntergleiten. Die Abstellplatte kann dadurch einfach gehandhabt werden, da sie nicht unvermittelt im hinteren Bereich durch ihr Gewicht nach unten beim Herausziehen abfällt. Dabei ist es aber auch möglich, die Seitenränder der Abstellplatte zumindest über eine Teillänge in Einschubrichtung zur Rückkante hin keilförmig aufeinander zulaufen zu lassen und die Auflagebahnen in ihrer waagerechten Ebene entsprechend aufeinander zuzuneigen. Wird hierbei die Abstellplatte nach vorn von den Auflagebahnen abgezogen, dann löst sich mindestens ein Seitenrand aus dem Eingriff mit der zugehörigen Auflagebahn, so daß sie ebenfalls ohne Schwierigkeiten aus dem Innenraum entnommen werden kann, selbst wenn die Tür oder deren Einbauteile vor den Öffungsquerschnitt des Innenbehälters reichen. Dabei enden die Auflagebahnen auch hier mit entsprechendem Abstand von der Öffnungsebene des Innenbehälters. Der Abstand kann deutlich kleiner als bei gestufter Ausführung der Seitenränder gehalten werden.In one embodiment of the cooling device according to the invention, the recessed edge sections of the storage plate can extend continuously up to the rear edge of the storage plate running parallel to the rear wall of the inner container, the support of the storage plate in the rear area being provided by support track sections provided on the side walls of the inner container, which are opposite to the Support web sections, which cooperate with the unchanged front edge sections of the storage plate, correspondingly protrude further into the interior of the inner container. These support track sections are also preferably part of an appropriately designed U-shaped guide groove for the storage plate. Since the recessed edge sections are therefore free from cantilevering to the adjacent support track Support elements are, the notches can extend continuously from the front unchanged edge sections to the rear rear edge of the storage plate. Such straight contours are not only easy to implement in plastic or metal versions but also in glass versions of the storage shelf. The support web sections for the recessed side edge sections, which are preferably molded in one piece into the side walls of the inner container and only protrude deeper into the interior, only require a corresponding configuration of the drawing or injection molds for the inner container made of plastic. With a simplified contour design, the options for removing the storage plate are fully retained. In the case of the one-step recessed edge sections, the area of overlap of the recessed edge section with the advanced support sheet section in the insertion direction can be formed longer than the overlap area between the other sections of the unchanged side edges and associated support sheets. The specific contact pressure of the storage plate is hereby significantly reduced in the rear area compared to a pin solution and it is ensured that the front unchanged side edge sections slide off the associated support tracks before the recessed side edge sections slide off the associated support track sections. The shelf can be easily handled because it does not suddenly drop down in the rear area due to its weight when pulled out. However, it is also possible to have the side edges of the storage plate wedge-shaped toward one another at least over a partial length in the direction of insertion toward the rear edge and to incline the support tracks in their horizontal plane accordingly. If the storage plate is pulled forward from the support tracks, at least one side edge is released from engagement with the associated support track, so that it can also be removed from the interior without difficulty, even if the door or its installation parts are in front of the opening cross section of the inner container pass. The support tracks also end here at a corresponding distance from the opening level of the inner container. The distance can be kept significantly smaller than with a stepped design of the side edges.

Die Erfindung ist nachfolgend anhand der Zeichnung von Ausführungsbeispielen näher erläutert.The invention is explained below with reference to the drawing of exemplary embodiments.

Ein Kühl- oder Gefrierschrank, bei dem die notwendige Tür nicht dargestellt ist, weist eine geschäumte Wärmeisolierung 1 zwischen einem Außengehäuse 2 und einem beispielsweise aus Kunststoff gespritzten oder im Vakuumverfahren hergestellten Innenbehälter 3 auf. An sich gegenüber stehenden , senkrechten Seitenwänden 4 des Innenbehälters sind Auflagebahnen 5 für Abstellplatten 6 angesetzt oder angeformt, die vorzugsweise durch den unten liegenden Schenkel von U-förmigen Nuten gebildet werden, die in waagerechter Richtung in die Tiefe des Innenbehälters 3 hin offen sind.A refrigerator or freezer, in which the necessary door is not shown, has a foamed thermal insulation 1 between an outer housing 2 and an inner container 3, for example injection molded from plastic or produced in a vacuum process. On opposite, vertical side walls 4 of the inner container, support tracks 5 for storage plates 6 are attached or molded on, which are preferably formed by the lower leg of U-shaped grooves, which are open in the horizontal direction in the depth of the inner container 3.

Die Ausgestaltungen des Innenbehälters gemäß den Fig. 2 - 4 sind insbesondere für eine Abstellplatte vorzugsweise mit einstufig an den gegenüberliegenden Seitenrändern 7 zurückgesetzten Seitenrandabschnitten 7.1 geeignet. Die in der Betriebslage gemäß Fig. 2 vorn liegenden Seitenrandabschnitte 7.2 weisen einen gegenseitigen Abstand voneinander auf, der größer als der lichte Abstand zwischen den aufeinander zu weisenden freien Rändern der Auflagebahnen 5 ist. Die sich nach hinten zur Rückkante 8 anschließenden, demgegenüber stufig zurückgesetzten Randabschnitte 7.1 verlaufen über ihre gesamte Länge bis zur Rückkante 8 parallel zu der durch einen Pfeil 9 angedeuteten Einschubrichtung bzw. der parallel dazu verlaufenden Mittellinie 10 der Abstellplatte. Die zurückgesetzten Randabschnitte 7.1 sind demnach frei von zu benachbarten Auflagebahnen 5 auskragenden Auflageelementen. Um hier ein Abkippen der Abstellplatte 6 zu verhindern, sind die betreffenden rückwärtigen Auflagebahnabschnitte 5.1 gegenüber den den unveränderten Seitenrandabschnitten 7.2 zugeordneten Auflagebahnabschnitten 5.2 weiter zur Mitte des Innenbehälters hin zusätzlich so weit ausgeformt, daß sie zumindest Teile der zurückgesetzten Randabschnitte 7.1 untergreifen. Der Überdeckungsbereich des zurückgesetzten Randabschnitts 7.1 mit dem zugeordneten, vorgezogenen Auflagebahnabschnitt 5.1 kann in Einschubrichtung 9 länger als der Überdeckungsbereich zwischen den übrigen Abschnitten 7.2 der Seitenränder 7 und der zugehörigen Auflagebahnabschnitte 5.2 sein. Hierdurch wird die spezifische Auflagebelastung minimiert und es wird ein plötzliches Absinken der hinteren Kante vor der vorderen bei der Handhabung durch den Benutzer vermieden.The configurations of the inner container according to FIGS. 2-4 are Particularly suitable for a storage shelf, preferably with one-stage recessed side edge sections 7.1 on the opposite side edges 7. The side edge sections 7.2 lying at the front in the operating position according to FIG. 2 are at a mutual distance from one another which is greater than the clear distance between the free edges of the support webs 5 to be pointed towards one another. The edge sections 7.1, which are connected to the rear edge 8 and are set back in comparison thereto, run over their entire length up to the rear edge 8 parallel to the insertion direction indicated by an arrow 9 or the center line 10 of the storage plate running parallel thereto. The recessed edge sections 7.1 are accordingly free from support elements which project to adjacent support tracks 5. In order to prevent the storage plate 6 from tipping over here, the rear support web sections 5.1 in question are further shaped towards the center of the inner container compared to the support web sections 5.2 assigned to the unchanged side edge sections 7.2 so that they engage under at least parts of the recessed edge sections 7.1. The area of overlap of the recessed edge section 7.1 with the associated, advanced support sheet section 5.1 can be longer in the insertion direction 9 than the overlap area between the other sections 7.2 of the side edges 7 and the associated support sheet sections 5.2. As a result, the specific contact load is minimized and a sudden lowering of the rear edge in front of the front edge during handling by the user is avoided.

Gemäß Fig. 3 verläuft der Grund 11 der jeweiligen Auflagebahn 5 über seine ganze Länge in Einschubrichtung 9 stufenlos und parallel zur Einschubrichtung in der Ebene der dazugehörigen Seitenwände 4. Dadurch können im Bedarfsfall zwischen die Auflagebahnen 5 Ablageplatten eingefügt werden, deren gegenüberliegende Seitenränder unverändert sind und einen gegenseitigen Abstand wie die Seitenrandabschnitte 7.2 haben. Insbesondere können derartige Abstellplatten quer zur Einschubrichtung geteilt sein, so daß sie ohne besondere Konturengestaltung ihrer Seitenränder in die die Auflagebahnen 5 bildenden Führungsnuten aus einer gegebenenfalls geschwenkten Lage eingeschoben werden können. Die Zentrierung der Hinterkante im Gehäuse kann durch nicht dargestellte Anziehungen am Ende der Auflagebahnabschnitte 5.1 erfolgen. Soll jedoch eine optimale Stärke der Wärmeisolierung 1 erreicht werden, kann die Breite der Auflagebahnen 5 quer zur Einschubrichtung 9 über die gesamte Länge gleich bleiben, wie es Fig. 4 zeigt. Dann ergibt sich im vorgezogenen Auflagebahnabschnitt 5.1 eine größere Isolierstoffstärke und damit ein geringerer Energieverlust. Gleichzeitig wird die Zentrierung der Abstellplatte verbessert.According to FIG. 3, the base 11 of the respective support sheet 5 runs continuously over its entire length in the insertion direction 9 and parallel to the insertion direction in the plane of the associated side walls 4. This means that, if necessary, 5 storage plates can be inserted between the support sheets, the opposite side edges of which are unchanged and have a mutual distance as the side edge sections 7.2. In particular, such storage plates can be divided transversely to the direction of insertion, so that they can be inserted from a possibly swiveled position without a special contour design of their side edges in the guide grooves forming the support tracks 5. The The rear edge in the housing can be centered by means of attractions (not shown) at the end of the support track sections 5.1. However, if an optimal thickness of the thermal insulation 1 is to be achieved, the width of the support webs 5 can remain the same across the entire length, as shown in FIG. 4. Then there is a greater thickness of insulating material in the advanced support sheet section 5.1 and thus less energy loss. At the same time, the centering of the shelf is improved.

Daneben ist es auch möglich, gemäß den Fig. 5 - 7 sowohl die Seitenränder 7 der Abstellplatte 6 zumindest über eine Teillänge in Einschubrichtung 9 zur Rückkante 8 hin keilförmig aufeinander zulaufen zu lassen, wobei diese Verjüngung des Abstands auch auf die Auflagebahnen 5 übertragen ist. Die Auflagebahnen 5 enden auch hier mit Abstand von der Öffnungsebene des Innenbehälters 3. Durch die aufeinander zulaufende Neigung sowohl der Seitenränder 7 als auch der Auflagebahnen 5 wird ein keilförmiger Eingriff der Abstellplatte 6 im Innenbehälter 3 erreicht. Die Auflagebahnen 5 sind dabei gleichbleibend breit über ihre gesamte Länge ausgestaltet und verlaufen parallel zu den Seitenrändern 7 der Abstellplatte 6. Die Breite der so trapezförmig geformten Abstellplatte 6 ist so bemessen, daß sie in der Einbaulage gemäß Fig. 6 voll auf den Auflagebahnen 5 aufliegt. Die Breite der Abstellplatte 6 ist dabei entsprechend dem lichten Maß zwischen den Seitenwänden 4 des Innenbehälters 3 gewählt. Bei dieser Ausgestaltung können die beiden Seitenränder über ihre Gesamtlänge stufenlos sein. Um die Abstellplatte 6 demnach aus dem Innenbehälter entnehmen zu können, braucht sie lediglich um einen solchen Weg entgegen der Einschubrichtung 9 von den Auflagebahnen 5 nach vorn gezogen zu werden, bis insbesondere ihre parallel zur Rückwand 12 des Innenbehälters 3 verlaufende Rückkante kürzer ist, als der lichte Abstand zwischen den Auflagebahnen 5 in diesem Bereich. Bei größerer Nuthöhe genügt es, wenn die hintere Kante kürzer ist als der lichte Abstand zwischen den Auflagebahnen plus eine Auflagenbreite in diesem Bereich. Die Abstellplatte 6 kann dann geschwenkt und daher auch dann aus dem Innenbehälter 3 herausgenommen werden, wenn Einbauteile der Tür vor die Öffnungsebene des Innenbehälters 3 greifen. Die Seitenwände 4 verlaufen bei dieser Anordnung vom Ende der betreffenden Auflagebahnen 5 aus bis zur Öffnungsebene parallel zueinander, während sich der Abstand zwischen dem Außengehäuse 2 und dem Innenbehälter zur Rückwand 12 hin aufgrund der nach hinten aufeinander zugeneigten Auflagebahnen 5 vergrößert. Dadurch wird auch die Stärke der Wärmeisolierschicht größer und der Energieverlust beim Betrieb des Kühlgerätes vermindert.In addition, it is also possible, according to FIGS. 5-7, for both the side edges 7 of the storage plate 6 to run towards one another in a wedge shape at least over a partial length in the insertion direction 9 towards the rear edge 8, this narrowing of the distance also being transmitted to the support tracks 5. The support sheets 5 also end here at a distance from the opening plane of the inner container 3. Due to the converging inclination of both the side edges 7 and the support sheets 5, a wedge-shaped engagement of the storage plate 6 in the inner container 3 is achieved. The support sheets 5 are designed to be uniformly wide over their entire length and run parallel to the side edges 7 of the storage plate 6. The width of the trapezoidal-shaped storage plate 6 is dimensioned such that it rests fully on the support sheets 5 in the installed position according to FIG. 6 . The width of the storage plate 6 is chosen according to the clear dimension between the side walls 4 of the inner container 3. In this embodiment, the two side edges can be stepless over their entire length. In order to be able to remove the storage plate 6 from the inner container, it only needs to be pulled forward in such a way against the insertion direction 9 from the support tracks 5 until in particular its rear edge, which runs parallel to the rear wall 12 of the inner container 3, is shorter than that clear distance between the support sheets 5 in this area. If the groove height is larger, it is sufficient if the rear edge is shorter than the clear distance between the support tracks plus a support width in this area. The storage plate 6 can then be pivoted and therefore also be removed from the inner container 3 when built-in parts of the door reach in front of the opening level of the inner container 3. The side walls 4 run in this Arrangement from the end of the respective support sheets 5 to the opening plane parallel to each other, while the distance between the outer housing 2 and the inner container to the rear wall 12 increases due to the backward inclined support sheets 5. This also increases the thickness of the thermal insulation layer and reduces the energy loss during operation of the cooling device.
