Description
Die vorliegende Erfindung bezieht sich auf eine Kühlraumtür mit einem Türrahmen, einem Türblatt und einer ein Aufschwenken des Türblatts aus einer Schließstellung in Offenstellungen ermöglichende Lagerung des Türblatts.The The present invention relates to a refrigerator door with a door frame, a door leaf and one swiveling the door leaf from a closed position enabling in open positions Storage of the door leaf.
Aus dem Stand der Technik sind Kühlraumtüren bekannt, die einen Kühlraum von einem Raum mit höheren Temperaturen trennen. Bei dem Kühlraum kann es sich um einen Tiefkühlraum handeln, aber auch um einen Raum, der nur auf Temperaturen von beispielsweise 8° heruntergekühlt ist, um dort kurzfristig zu verbrauchende Lebensmittel lagern zu können. Der Kühlraum kann als großer Raum ausgebildet sein, er kann jedoch auch als eine Art Container oder begehbarer Schrank ausgebildet sein. Im Normalfall weisen die Kühlraumtüren einen Schließmechanismus auf, durch den die Kühlraumtür in einer Schließstellung gehalten wird. Ein ordnungsgemäßer Verschluß der Kühlraumtür ist erforderlich, um die Dichtungen, die im Anschlagsbereich der Tür zum Rahmen angebracht sind, sicher zur Anlage auf die gegenüberliegende Dichtfläche zu bringen und um auf diese Weise unerwünschte Ver luste von Kaltluft aus dem Kühlraum zu vermeiden.Out refrigerator doors are known in the prior art, the a cold room from a room with higher Separate temperatures. At the refrigerator it can be a freezer room act, but also to a room that only at temperatures of, for example Cooled down to 8 °, to be able to store food there at short notice. Of the refrigerator can be great However, it can also be designed as a kind of container or walk-in closet be formed. Normally, the Refrigerator doors one closing mechanism on, through which the refrigerator door in a closed position is held. A proper closure of the refrigerator door is required around the seals that are attached in the stop area of the door to the frame, safe to rest on the opposite sealing surface to bring and in this way undesirable losses of cold air the refrigerator to avoid.
Der hinter der Kühlraumtür liegende Kühlraum wird im Regelfall nur aufgesucht, um entweder im Kühlraum gelagerte Waren aus dem Kühlraum herauszutragen oder entsprechende Waren in den Kühlraum hineinzubringen. Jedesmal, wenn eine Person durch die Kühlraumtür hindurchtritt, hält diese Person Kühlwaren in der Hand. Wegen dieses Umstandes ist es sehr lästig, bei jedem Passieren der Kühlraumtür zunächst die Verriegelung öffnen zu müssen, bevor die Tür durchschritten werden kann. Auch muß nach jeder Benutzung der Kühlraumtür diese wieder verriegelt werden, um Kühlverluste zu vermeiden.Of the behind the cold room door refrigerator is usually only visited to either stored in the refrigerator Goods from the refrigerator carry out or bring appropriate goods into the refrigerator. every when a person passes through the refrigerator door, Hold this person frozen goods in the hand. Because of this circumstance, it is very annoying at each passing the refrigerator door first the Open the lock to have to, before the door can be passed. Also must after each use of the Refrigerator door this be locked again to prevent cooling losses to avoid.
Um bei der Benutzung einer Kühlraumtür nicht jedesmal die zu transportierende Kühlware ablegen zu müssen, wurden Schließmechanismen entwickelt, die mit dem Fuß oder dem Ellenbogen einer Person bedienbar sind. Aber auch die Betätigung solcher Mechanismen hält die Bedienperson auf, und es kann passieren, daß während der Öffnung oder des Schließens der Kühlraumtür Kühlware auf den Boden fällt. Des weiteren sind motorisch angetriebene Kühlraumtüren bekannt, die zusammen mit der motorischen Betätigung zusätzlich motorisch verriegelt und entriegelt werden. Die Antriebe – im Regelfall elektrisch – sind jedoch sehr kostenintensiv und wartungsanfällig. Ein besonderes Problem ergibt sich bei elektrischen Antrieben für Kühlraumtüren auch daraus, daß im Zusammenhang mit der Kühlung eine erhebliche Menge an Feuchtigkeit anfällt und die Motoren und Schalter entsprechend isoliert werden müssen.Around when using a refrigerator door not each time the refrigerated goods to be transported had to be deposited closing mechanisms developed with the foot or the elbow of a person are operable. But also the operation of such Holds mechanisms the operator, and it may happen that during the opening or closing of the Refrigerator door chilled goods on the ground falls. Furthermore, motor-driven refrigerator doors are known, which together with the motor actuation additionally motor locked and unlocked. The drives - as a rule electric - are but very expensive and maintenance-prone. A special problem arises in electrical drives for cold room doors also from the fact that in connection with the cooling a significant amount of moisture accumulates and the motors and switches must be isolated accordingly.
Es ist Aufgabe der vorliegenden Erfindung, Kühlraumtüren so zu verbessern, daß diese ohne die Betätigung besonderer Verriegelungsmechanismen benutzbar ist.It Object of the present invention to improve refrigerator doors so that this without the operation special locking mechanisms is usable.
Die Erfindung wird für eine gattungsgemäße Kühlraumtür gelöst, indem die Lagerung aus zumindest einem Drehzapfen besteht, um dessen annähernd vertikal aus gerichtete Drehachse das Türblatt schwenkbar ist, und die Kühlraumtür von einem Kraftspeicher schließbar ist.The Invention is for a generic refrigerator door solved by the bearing consists of at least one pivot about its approximately vertical The door leaf can be swiveled out of a directed axis of rotation is, and the refrigerator door from a power storage closable is.
Der Vorteil einer Drehzapfenlagerung ist darin zu sehen, daß die Dichtungen, die die Kühlraumtür umfangsseitig gegen Wärmeverluste abdichten, bei einer Öffnung der Kühlraumtür in geringerem Umfang gequetscht werden als bei einer herkömmlichen Lagerung einer Kühlraumtür in Türangeln. Dadurch kann die Kühlraumtür trotz der umlaufenden Dichtungen mit geringen Kraftaufwand geöffnet werden. Eine Drehzapfenlagerung ist im Vergleich zu herkömmlichen Pendeltürbeschlägen auch besser gegen Wärmeverluste zu isolieren. Da die Kühlraumtür so leichgängig bewegbar ist, kann das Türblatt mit einem Kraftspeicher wirkverbunden werden, der bei einer Öffnungsbewegung des Türblatts Rückstellkräfte aufbaut. Sobald das geöffnete Türblatt freigegeben wird, kann es leicht von dem Kraftspeicher anhand der darin gespeicherten Energie wieder in die Schließstellung zurückbewegt werden. Der Kraftspeicher ist auf einfache Weise mit einer Drehzapfenlagerung verbindbar, da eine solche Lagerung – anders als herkömmliche Pendeltürbeschläge – einen immer gleichen Schwenkweg aufweist. Dadurch werden die Dichtkanten der Dichtungsgummi insbesondere über die gewünschte lange Gebrauchsdauer geschont und können mit großer Präzision genau an die Einbaumaße angepaßt werden. Die Dichtungsgummis müssen keine großen Maßtoleranzen auffangen, brauchen nur in geringem Maß flexibel zu sein, benötigen nur geringe Stauchungskräfte bis zur dicht schließenden Anlage an die Dichtflächen und weisen so eine dauerhaft hohe Dichtigkeit gegen Wärmeverluste auf. Die Kombination einer Drehzapfenlagerung mit einem Kraftspeicher ermöglicht also eine Kühlraumtür, die leicht zu betätigen ist, die aber trotzdem eine insgesamt sehr hohe Kälteisolierung im Bereich der Dichtungen ohne eine besondere Verriegelung aufweist.Of the Advantage of a pivot bearing is the fact that the seals, the refrigerator door is circumferentially against heat loss seal, at an opening the refrigerator door in lower Be squeezed circumference than in a conventional storage of a refrigerator door in hinges. This allows the refrigerator door despite the circumferential seals are opened with little effort. A pivot bearing is compared to conventional swing door fittings also better against heat loss to isolate. Because the refrigerator door so easy to move is, can the door leaf be operatively connected to an energy storage, which in an opening movement of the door leaf Builds restoring forces. Once the open door leaf is released, it can be easily from the energy store based on the stored energy back into the closed position become. The energy storage is in a simple way with a pivot bearing connectable, since such storage - unlike conventional Swing door fittings - one always has the same pivoting. This will cause the sealing edges the sealing rubber in particular on the desired long life spared and can accurately with great precision to the installation dimensions customized become. The sealing rubbers need no big ones tolerances only need a small amount of flexibility, only need to be flexible low compression forces until the tight closing Attachment to the sealing surfaces and thus have a permanently high density against heat loss on. The combination of a pivot bearing with a power storage allows so a fridge door that is light to press is, but still a very high overall cold insulation in the area of seals without a special lock has.
Eine ausreichend große Durchtrittsöffnung ergibt sich, wenn der Drehzapfen außermittig zur Türbreite angeordnet ist. Nach einer bevorzugten Ausgestaltung der Erfindung ist vorgesehen, das Türblatt aus der Schließstellung in zwei Richtungen schwenkbar auszulegen, so daß die Kühlraumtür aus jeder Richtung kommend genutzt werden kann, ohne einen Griff oder eine Verriegelung betätigen zu müssen.A sufficiently large passage opening results when the trunnion is arranged eccentrically to the door width. According to a preferred embodiment of the invention, the door leaf from the closed position in two directions designed to be pivotable, so that the refrigerator door can be used coming from any direction without having to operate a handle or a lock sen.
