Description

Die Erfindung betrifft ein Kühlgerät.The invention relates to a cooling device.

Bei einem zum Stand der Technik gemäß Artikel 54(3) EPÜ gehörenden Kühlgerät (EP-A-0 507 754) ist ein wärmeisoliert in einem Außengehäuse angeordneter Innenbehälter für die Aufnahme von zu kühlendem Gut vorgesehen, bei dem parallel zur Rückwand mit Abstand ein platinenförmiger Verdampfer angeordnet ist. Zur Befestigung des Verdampfers sind in die von der Rückwand weglaufenden senkrechten Seitenwände einander gegenüberliegende, nach außen gerichtete Nuten eingeformt, in welche elastisch komprimierbare Profilstreifen eingelegt sind. Bei einer Ausgestaltung ist der Abstand der senkrechten Seitenränder voneinander größer als die lichte Weite zwischen den senkrechten Seitenwänden des Innenbehälters, so daß bei der Montage der Verdampfer in schräger Lage zunächst mit einem seiner Seitenränder auf einen Profilstreifen aufgesetzt wird. Durch weiteres Einschieben des anderen Seitenrandes zur Rückwand des Innenbehälters hin wird der erste Profilstreifen gestaucht, so daß der gegenüberliegende Seitenrand des Verdampfers schließlich in die zugehörige Nut bzw. auf den darin liegenden Profilstreifen schnappen kann. Unter teilweiser Dekomprimierung des ersten Profilstreifens sinkt dann der gegenüberliegende Seitenrand des Verdampfers um ein entsprechendes Maß in die gegenüberliegende Nut bzw. den darin angeordneten Profilstreifen ein, wodurch der Verdampfer im Innenbehälter festgelegt ist. Abgesehen davon, daß die Nuten für die Halterung des Verdampfers Hinterschneidungen bilden, die beim Entformen des aus Kunststoff herzustellenden Innenbehälters Probleme mit sich bringen können, kann die Halterung des Verdampfers in hygienischer Hinsicht Probleme bereiten.In the case of a cooling device belonging to the prior art according to Article 54 (3) EPC (EP-A-0 507 754), an inner container is arranged in a heat-insulated manner in an outer housing for holding goods to be cooled, in which a plate-shaped one is arranged parallel to the rear wall at a distance Evaporator is arranged. To fasten the evaporator, mutually opposite, outwardly directed grooves are formed in the vertical side walls running away from the rear wall, in which elastically compressible profile strips are inserted. In one embodiment, the distance between the vertical side edges from one another is greater than the clear width between the vertical side walls of the inner container, so that when the evaporator is installed in an inclined position, one of its side edges is first placed on a profile strip. By pushing the other side edge further towards the rear wall of the inner container, the first profile strip is compressed, so that the opposite side edge of the evaporator can finally snap into the associated groove or onto the profile strip located therein. With partial decompression of the first profile strip, the opposite side edge of the evaporator then sinks by a corresponding amount into the opposite groove or the profile strip arranged therein, as a result of which the evaporator is fixed in the inner container. Apart from the fact that the grooves for the mounting of the evaporator form undercuts which are produced when the plastic is removed from the mold Can cause problems with the inner container, the mounting of the evaporator can cause hygienic problems.

Bei einem weiteren bekannten Kühlgerät (DE-AS 12 53 733) befindet sich in einem Innenbehälter, der für die Aufnahme von zu kühlendem Gut vorgesehen ist, ein Verdampfer für Kältemittel, der mit Abstand parallel zur senkrechten Rückseitenwand des Innenbehälters angeordnet ist. Mit Abstand vor dem plattenförmigen Verdampfer steht eine Trennwand, die den Verdampfer gegenüber dem Nutz-Innenraum des Innenbehälters abdeckt. Zwischen der Deckwand des Innenbehälters und der Trennwand bzw. dem Verdampfer befindet sich ein Spalt, durch den Luft aus dem Innenbehälter-Nutzraum zum Verdampfer strömen kann, die nach der Abkühlung am Verdampfer im Schacht zwischen der Innenbehälter-Rückwand und der Trennwand frei nach unten in den Nutzraum des Innenbehälters zurückströmt. Bei diesem Aufbau sind getrennte Halterungen für den Verdampfer und die Trennwand erforderlich.In another known cooling device (DE-AS 12 53 733), an evaporator for refrigerant is located in an inner container, which is provided for receiving goods to be cooled, and is arranged at a distance parallel to the vertical rear wall of the inner container. At a distance from the plate-shaped evaporator is a partition that covers the evaporator from the useful interior of the inner container. There is a gap between the top wall of the inner container and the partition or the evaporator, through which air can flow from the inner container usable space to the evaporator, which after cooling down on the evaporator in the shaft between the inner container rear wall and the partition freely downwards flows back the useful space of the inner container. This construction requires separate brackets for the evaporator and the partition.

Der Erfindung liegt die Aufgabe zugrunde, bei einem Kühlgerät Maßnahmen zu treffen, die mit einfachen Mitteln eine Befestigung des Verdampfers ermöglichen.The invention has for its object to take measures in a refrigerator that allow attachment of the evaporator with simple means.

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

Gemäß der Erfindung wird der Verdampfer auf im Eckbereich zwischen der Rückwand und den angrenzenden Seitenwänden ausgeformten Befestigungsleisten festgesetzt. Der Verdampfer erscheint dann als Teil der Rückwand des Innenbehälters. Die Befestigungsleisten können aber auch stufenförmig abgesetzt sein, so daß die in die Tiefe hineinlaufenden Seitenflanken der Stufe die benachbarten Umfangskanten des Verdampfers einfassen. Zumindest die senkrechten Seitenkanten des Verdampfers, vorzugsweise aber auch die obere und untere Seitenkante können mit Rahmenleisten bestückt sein, die gegebenenfalls auch als umspritzter Rahmen hergestellt werden können. Mit den Rahmenleisten kann dieser Verdampfer wiederum auf den Befestigungsleisten festgesetzt werden. Die Rahmenleisten überdecken dabei auch im Randbereich des Verdampfers vorgesehene Rohranschlüsse oder andere Unregelmäßigkeiten bzw. scharfe Kanten. Der Verdampfer kann jedoch auch auf seiner dem Nutzraum des Innenbehälter zugewandten Seite mit einer Platte fest verbunden sein, deren Randbereiche an den Befestigungsleisten festgesetzt werden können. Der Verdampfer kann dann in seiner Kontur beliebig gestaltet werden und insbesondere schmaler als der freie Raum zwischen den Befestigungsleisten sein. Diese Platte kann dabei aus einem Material bestehen, das insbesondere in seiner Farbe dem des Innenbehälters angepaßt ist. Sie kann jedoch auch aus wärmeleitendem und wärmespeichernden Material bestehen, so daß die Kältespeicherkapazität des Verdampfers erhöht wird. Dadurch wird der Verdampfungsdruck im Verdampfer längere Zeit auf einem hohen Wert gehalten, wodurch sich eine Verbesserung des Kühlungswirkungsgrades ergibt. Zur Erhöhung der Wärmeübertragungsleistung kann der Verdampfer jedoch auch auf seiner der Seitenwand des Innenbehälters zugewandten Seitenfläche senkrecht verlaufende Rippen aufweisen oder gefaltet sein, wobei die Faltkanten senkrecht verlaufen. Daneben ist es zweckmäßig, wenn der Verdampfer waagerechte Schlitze im Bereich von geschlossenen, im Innenbehälter angeordneten Fachböden aufweist und in die Schlitze Kühlluftabweiser eingreifen zu lassen, durch welche die nach unten fallende gekühlte Luft in den Raum zwischen zwei Fachböden einströmt, wodurch in jeder dieser Kühlzonen eine eigene Luftumwälzung eintritt.According to the invention, the evaporator is fixed on fastening strips formed in the corner area between the rear wall and the adjacent side walls. The evaporator then appears as part of the rear wall of the inner container. The fastening strips can, however, also be stepped, so that the side flanks of the step that run into the depth enclose the adjacent peripheral edges of the evaporator. At least the vertical side edges of the evaporator, but preferably also the upper and lower side edges, can be equipped with frame strips, which can optionally also be produced as an overmolded frame. With the frame strips, this evaporator can in turn be fixed on the mounting strips. The frame strips also cover pipe connections provided in the edge region of the evaporator or other irregularities or sharp edges. However, the evaporator can also be firmly connected on its side facing the useful space of the inner container to a plate, the edge regions of which can be fixed on the fastening strips. The contour of the evaporator can then be designed as desired and in particular can be narrower than the free space between the fastening strips. This plate can consist of a material that is matched in particular to the color of the inner container. However, it can also consist of heat-conducting and heat-storing material, so that the cold storage capacity of the evaporator is increased. As a result, the evaporation pressure in the evaporator is kept at a high value for a long time, which results in an improvement in the cooling efficiency. To increase the heat transfer capacity, however, the evaporator can also have ribs running vertically on its side surface facing the side wall of the inner container, or can be folded, the Folded edges run vertically. In addition, it is expedient if the evaporator has horizontal slots in the area of closed shelves arranged in the inner container and to allow cooling air deflectors to engage in the slots, through which the cooled air falling down flows into the space between two shelves, as a result of which in each of these cooling zones own air circulation occurs.

In einem Gehäuse 1 eines Kühl- oder Gefrierschranks befindet sich ein Innenbehälter 2, wobei der Zwischenraum zwischen dem Gehäuse 1 und dem Innenbehälter 2 mit einer Wärmeisolierung 3 insbesondere ausgeschäumt ist. Im oberen Abschnitt des Innenbehälters 2 sitzt parallel zur Rückwand 4 mit einem geringem Abstand, beispielsweise 10 mm, ein platinenförmiger Verdampfer 5, der über nicht dargestellte Rohrleitungen mit einem Kältekreislauf verbunden ist. Von der durch eine Tür zu verschließenden offenen Seite 6 aus befinden sich im Nutzraum für die Einbringung von zu kühlendem Gut vor dem Verdampfer 5 geschlossene Fachböden 7 in unterschiedlichen Höhen.An inner container 2 is located in a housing 1 of a refrigerator or freezer, the space between the housing 1 and the inner container 2 being foamed in particular with thermal insulation 3. In the upper section of the inner container 2, parallel to the rear wall 4, with a small distance, for example 10 mm, sits a plate-shaped evaporator 5, which is connected to a refrigeration circuit via pipes, not shown. From the open side 6 to be closed by a door there are closed shelves 7 at different heights in the usable space for introducing material to be cooled in front of the evaporator 5.

Zur Befestigung des Verdampfers 5 sind im Eckbereich am Übergang von der Rückwand 4 zu den senkrechten Seitenwänden 8 Befestigungsleisten 9 vorgesehen, die über die Ebene der Rückwand 4 zur Öffnungsseite 6 hin erhaben sind. Diese Befestigungsleisten 9 sind einstückig mit dem Innenbehälter 2 verbunden und bei seiner Herstellung mit angeformt worden. Auf diesen senkrecht verlaufenden Befestigungsleisten 9 ist der als ebene Platine ausgebildete Verdampfer 5 mit Abstand von der Rückwand 4 im Bereich seiner senkrechten Seitenränder 10 festgesetzt.To attach the evaporator 5 8 mounting strips 9 are provided in the corner area at the transition from the rear wall 4 to the vertical side walls, which are raised above the plane of the rear wall 4 to the opening side 6. These mounting strips 9 are integrally connected to the inner container 2 and have been molded on during its manufacture. The evaporator 5, which is designed as a flat circuit board, is fixed at a distance from the rear wall 4 in the region of its vertical side edges 10 on these vertically extending fastening strips 9.

Gemäß der in den Figuren 1 bis 3 dargestellten Ausführungsform ist die Platine des Verdampfers 5 unmittelbar an den Befestigungsleisten 9 festgesetzt. Die Seitenränder 10 liegen dabei auf der der Öffnungsseite 6 zugewandten Flanke der Befestigungsleiste 9 auf. Wenn der Verdampfer nicht die gesamte Breite zwischen den Seitenwänden 8 einnimmt, ist es zweckmäßig, die Befestigungsleisten stufenförmig abzusetzen, so daß die Seitenränder 10 des Verdampfers 5 in die Befestigungsleiste so eingesenkt wenden können, daß auf der parallel zur Rückwand 4 verlaufenden Stufenflanke die Seitenränder 10 aufliegen und die senkrecht dazu gerichteten, in den Innenbehälter weisenden Stufenflanken die benachbarte Umfangskante der Seitenränder 10 seitlich abdecken. Bei angepaßter Stufentiefe ergibt sich so ein stufenfreier Übergang vom Verdampfer 5 zu den anschließenden Teilen der Befestigungsleisten 9 bzw. den Seitenwänden 8. Der Verdampfer 5 kann dabei auch mit Rahmenleisten versehen sein, welche zumindest die senkrechten Umfangskanten 10, vorzugsweise aber auch die obere und die untere waagerechte Umfangskante umschließen. Diese Rahmenleisten können dabei anstatt der senkrechten Umfangskante 10 zur Befestigung des Verdampfers 5 an den Befestigungsleisten 9 herangezogen werden.According to the embodiment shown in Figures 1 to 3, the circuit board of the evaporator 5 is fixed directly to the mounting strips 9. The side edges 10 lie on the side of the fastening strip 9 facing the opening side 6. If the evaporator does not occupy the entire width between the side walls 8, it is expedient to step down the fastening strips so that the Side edges 10 of the evaporator 5 can be sunk into the fastening strip so that the side edges 10 rest on the step flank running parallel to the rear wall 4 and the step flanks directed perpendicularly thereto and pointing into the inner container laterally cover the adjacent peripheral edge of the side edges 10. With an adapted step depth, there is a step-free transition from the evaporator 5 to the subsequent parts of the fastening strips 9 or the side walls 8. The evaporator 5 can also be provided with frame strips which have at least the vertical peripheral edges 10, but preferably also the upper and the Enclose the lower horizontal peripheral edge. These frame strips can be used instead of the vertical peripheral edge 10 for fastening the evaporator 5 to the fastening strips 9.

Es ist aber auch möglich, gemäß den Figuren 4 und 5 auf die dem Nutzraum des Innenbehälters 2, also den Fachböden 7 zugewandte Seite des Verdampfers eine denselben vollständig überdeckende Platte 11 aufzusetzen. Diese Platte 11 übergreift vorzugsweise alle Umfangskanten des Verdampfers 5 und ist mit dem Verdampfer 5 fest verbunden. Die seitlich überragenden Randzonen 12 der Platte 11 können wiederum für die Befestigung auf den Befestigungsleisten 9 herangezogen werden. Die Platte 11 kann insbesondere in der Farbe derjenigen des Innenbehälters angepaßt werden, so daß ein ästhetisch ansehnlicher rückwärtiger Abschluß des Innenbehälters gegeben ist. Die Platte 11 kann insbesondere aus Kunststoff bestehen, wenn eine einfache Verkleidung und Halterung für den Verdampfer 5 angestrebt wird. Sie kann jedoch auch aus wärmeleitendem und wärmespeichernden Material, insbesondere aus Stahlblech bestehen, wenn die Wärmekapazität des Verdampfers erhöht werden soll.However, it is also possible, according to FIGS. 4 and 5, to place a plate 11 completely covering the evaporator on the side of the evaporator facing the useful space of the inner container 2, that is to say the shelves 7. This plate 11 preferably overlaps all peripheral edges of the evaporator 5 and is firmly connected to the evaporator 5. The laterally projecting edge zones 12 of the plate 11 can in turn be used for fastening on the fastening strips 9. The plate 11 can in particular be adapted in color to that of the inner container, so that there is an aesthetically pleasing rear closure of the inner container. The plate 11 can in particular consist of plastic if a simple covering and mounting for the evaporator 5 is desired. However, it can also consist of heat-conducting and heat-storing material, in particular sheet steel, if the heat capacity of the evaporator is to be increased.

Um die Wirksamkeit des Verdampfers zu erhöhen, kann insbesondere seine der Rückwand 4 zugewandte Seitenfläche mit die Oberfläche vergrößernden Elementen, vorzugsweise Rippen 13 versehen sein, die in senkrechter Richtung parallel zueinander verlaufen. Der Verdampfer kann jedoch auch gefaltet sein, wobei die Faltkanten ebenfalls senkrecht verlaufen sollen. Die Rippen 13 bedecken dabei lediglich den freien Teil zwischen den Befestigungsleisten 9.To increase the effectiveness of the evaporator, you can in particular, its side surface facing the rear wall 4 can be provided with elements which enlarge the surface, preferably ribs 13, which run parallel to one another in the vertical direction. However, the evaporator can also be folded, with the folded edges also extending vertically. The ribs 13 only cover the free part between the fastening strips 9.

Der Verdampfer 5 kann im übrigen mit waagerecht verlaufenden Schlitzen versehen sein, die im Höhenbereich der Fachböden 7 angeordnet sind. In diese Schlitze 14 greifen Kühlluftabweser 15 ein, welche die im Spalt zwischen der Rückwand 4 und dem Verdampfer 5 nach unten strömende gekühlte Luft auf die Fachböden 7 ausleiten. Gemäß Figur 7 sind die Kühlluftabweise 15 als Ausformungen der Rückwand 4 ausgebildet. Sie können jedoch gemäß Figur 8 auch als separate Teile hergestellt werden, die im Bereich der Schlitze 14 festgesetzt werden. Es ist aber auch möglich, die den unteren Rand des Schlitzes 14 bildende Flanke des Verdampfers 5 nach rückwärts in den Spalt zwischen dem Verdampfer 5 und der Rückwand 4 zu neigen, um eine Ausleitung der gekühlten Luft zum jeweiligen Fachboden 7 zu unterstützen.The evaporator 5 can also be provided with horizontally extending slots which are arranged in the height region of the shelves 7. Cooling air deflectors 15 engage in these slots 14 and lead the cooled air flowing downward in the gap between the rear wall 4 and the evaporator 5 onto the shelves 7. According to FIG. 7, the cooling air deflectors 15 are formed as shapes of the rear wall 4. However, according to FIG. 8, they can also be produced as separate parts which are fixed in the area of the slots 14. It is also possible, however, to incline the flank of the evaporator 5 forming the lower edge of the slot 14 backwards into the gap between the evaporator 5 and the rear wall 4 in order to support a discharge of the cooled air to the respective shelf 7.
