Description
Die vorliegende Erfindung betrifft ein Kühl- und/oder Gefriergerät mit wenigstens einer Tür, die eine transparente und/oder transluzente Scheibe, vorzugsweise eine Glasscheibe aufweist.The present invention relates to a refrigerator and / or freezer with at least one door having a transparent and / or translucent pane, preferably a glass pane.
Derartige Kühl- und/oder Gefriergeräte sind in zahlreichen unterschiedlichen Ausführungsformen bekannt. Insbesondere bei hoher Luftfeuchtigkeit kann es zur Betauung der Türen bzw. der Türscheiben kommen, wobei diese Betauung physikalisch bedingt an jener Stelle am ausgeprägtesten ist, wo der kälteste Bereich des Gerätes ist. Dies ist üblicherweise der untere Bereich der Tür bzw. der Scheibe der Tür. Im allgemeinen findet die genannte Betauung insbesondere im unteren Drittel der Tür bzw. Türscheibe statt.Such refrigerators and / or freezers are known in numerous different embodiments. Especially at high humidity, it may come to the condensation of the doors or door panes, this condensation is physically most pronounced at the point where the coldest area of the device is. This is usually the lower portion of the door or the disc of the door. In general, the said condensation occurs in particular in the lower third of the door or door glass.
Um die Betauung zu verhindern, ist es aus dem Stand der Technik bekannt, Elektroheizungen einzusetzen, die den kritischen Bereich beheizen. Diese Beheizung kann speziell bei Glastüren mit Rahmen zum einen im Rahmen der Tür erfolgen oder es erfolgt eine flächige Beheizung der Glasscheibe selbst. Durch diese Wärmeinbringung verdunstet das Kondenswasser, wodurch es somit zu keiner bzw. zu einer reduzierten Wassertropfenbildung an der Glasscheibe kommt. Ein wesentlicher Nachteil dieser Art der Beheizung ist die zusätzliche Wärmeeinbringung mittels Elektroheizung, die sich negativ auf die Energiebilanz des Gerätes auswirkt.In order to prevent condensation, it is known from the prior art to use electric heaters that heat the critical area. This heating can be done especially in glass doors with frame on the one hand in the context of the door or there is a surface heating of the glass itself. By this heat input evaporates the condensation, making it to no or to a reduced drop of water on the glass comes. A major disadvantage of this type of heating is the additional heat input by means of electric heating, which has a negative effect on the energy balance of the device.
Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, ein Kühl- und/oder Gefriergerät der eingangs genannten Art dahingehend weiterzubilden, dass die Betauung wirksam und mit vergleichsweise einfachen Mitteln verhindert oder verringert wird.The present invention is therefore the object of developing a refrigerator and / or freezer of the type mentioned in such a way that the condensation is effectively prevented or reduced with relatively simple means.
Diese Aufgabe wird durch ein Kühl- und/oder Gefriergerät mit den Merkmalen des Anspruchs 1 gelöst.This object is achieved by a refrigerator and / or freezer with the features of claim 1.
Danach ist vorgesehen, dass das Gerät eine Warmluftquelle aufweist oder mit einer Warmluftquelle in Verbindung steht und dass das Gerät des Weiteren Luftführungsmittel aufweist, die mittelbar oder unmittelbar mit der Warmluftquelle in Verbindung stehen und die derart angeordnet sind, dass die Warmluft durch die Luftführungsmittel auf die Scheibe und/oder zumindest in den Bereich der Scheibe geleitet wird. Erfindungsgemäß ist somit vorgesehen, dass die Tür des Gerätes bzw. die Scheibe, die beispielsweise als Glas oder auch als Kunststoffscheibe ausgeführt sein kann, nicht bzw. nicht nur mittels Elektroheizung, sondern mittels eines warmen Luftstromes beheizt wird. Erfindungsgemäß ist somit vorgesehen, dass die Beheizung der Scheibe und damit die Verhinderung der Kondenswasserbildung ausschließlich oder zumindest auch mittels eines warmen Luftstromes erfolgt.Thereafter, it is provided that the device has a hot air source or is in communication with a source of hot air and that the device further comprises air guide means which are directly or indirectly with the hot air source in communication and which are arranged such that the hot air through the air guide means on the Disc and / or at least in the area of the disc is passed. According to the invention it is thus provided that the door of the device or the disc, which may be embodied for example as glass or as a plastic disc, not or not only by means of electric heating, but by means of a warm air flow is heated. According to the invention it is thus provided that the heating of the disc and thus the prevention of condensation takes place exclusively or at least by means of a warm air flow.
Dabei ist es besonders vorteilhaft, wenn die Warmluftquelle durch eine Komponente des Kältemittelkreislaufes, vorzugsweise durch den Verflüssiger und/oder durch den Kompressor des Gerätes gebildet wird. Diese Komponenten erzeugen Abwärme, die zur Erzeugung der Warmluft herangezogen werden kann. Die durch die Abwärme dieser Komponenten erwärmte Luft kann sodann mittels geeigneter Luftführungsmittel, beispielsweise mittels eines Gebläses und eines im Gerät und/oder in der Tür befindlichen Luftkanals oder dergleichen auf oder in den Bereich der Scheibe geführt werden. Da in diesem Fall die Warmluft durch die Abwärme vom Verflüssiger und/oder vom Kompressor oder von anderen Wärme erzeugenden Komponenten des Gerätes entsteht, gibt es keinen zusätzlichen negativen Einfluß auf die Energiebilanz des Gerätes.It is particularly advantageous if the hot air source is formed by a component of the refrigerant circuit, preferably by the condenser and / or by the compressor of the device. These components generate waste heat, which can be used to generate the hot air. The heated by the waste heat of these components air can then be performed by means of suitable air guide means, for example by means of a fan and an air duct located in the device and / or in the door or in the region of the disc. Since in this case the warm air is due to the waste heat from Condenser and / or produced by the compressor or other heat-generating components of the device, there is no additional negative impact on the energy balance of the device.
In weiterer Ausgestaltung der Erfindung ist vorgesehen, dass die Luftführungsmittel derart angeordnet sind, dass sie wenigstens abschnittsweise durch den Rahmen der Tür gebildet werden. Der Rahmen kann somit beispielsweise als Hohlprofil ausgeführt sein, durch die Warmluft geführt wird.In a further embodiment of the invention it is provided that the air guide means are arranged such that they are at least partially formed by the frame of the door. The frame can thus be designed, for example, as a hollow profile, is guided by the hot air.
In weiterer Ausgestaltung der Erfindung ist vorgesehen, dass die Tür wenigstens einen Warmlufteinlass aufweist, durch die Warmluft in wenigstens einen in der Tür befindlichen Hohlraum einführbar ist. Die Tür kann des Weiteren wenigstens einen Warmluftauslass aufweisen. Dieser steht vorzugsweise mit dem genannten Warmlufteinlass der Tür in Verbindung. Der Warmluftauslass hat die Funktion, die Warmluft auf die Scheibe oder in den Bereich der Scheibe zu führen, dadurch die Scheibe oder die im Bereich der Scheibe befindliche Luftschicht zu erwärmen und damit Betauung der Scheibe zu verhindern oder zu verringern.In a further embodiment of the invention, it is provided that the door has at least one hot air inlet through which hot air can be introduced into at least one cavity located in the door. The door may further comprise at least one hot air outlet. This is preferably in communication with said hot air inlet of the door. The purpose of the hot air outlet is to direct the warm air to the glass or into the area of the glass, thereby heating the glass or the layer of air in the area of the glass to prevent or reduce condensation on the glass.
Die Warmlufteinlass der Tür kann derart angeordnet sein, dass die Warmluft von außen auf die Scheibe oder von außen in den Bereich der Scheibe geführt wird. Denkbar ist es jedoch grundsätzlich auch, beispielsweise im Falle einer Doppelverglasung die Warmluft zwischen die beiden Scheiben der Doppelverglasung einzuführen.The hot air inlet of the door can be arranged such that the hot air is guided from the outside to the disc or from the outside into the region of the disc. It is conceivable, however, in principle, for example, in the case of double glazing to introduce the warm air between the two panes of double glazing.
In weiterer Ausgestaltung der Erfindung ist vorgesehen, dass der Warmlufteinlass der Tür und/oder der Warmluftauslass der Tür im Rahmen der Tür angeordnet sind.In a further embodiment of the invention it is provided that the warm air inlet of the door and / or the hot air outlet of the door are arranged in the frame of the door.
In bevorzugter Ausgestaltung der Erfindung ist der Warmluftauslass der Tür im unteren Bereich der Tür angeordnet, da dort in erster Linie mit der Betauung der Scheibe zu rechnen ist. Der Warmlufteinlass kann im oberen Bereich der Tür angeordnet sein. Grundsätzlich sind jedoch auch davon abweichende Anordnungen, beispielsweise eine seitliche Einführung der Warmluft in die Tür bzw. in den Türrahmen oder einer oder mehrerer seitlich angeordneten Warmluftauslässe denkbar.In a preferred embodiment of the invention, the warm air outlet of the door is arranged in the lower region of the door, since there is to be expected in the first place with the condensation of the disc. The warm air inlet can be arranged in the upper area of the door. Basically, however, are deviating arrangements, For example, a lateral introduction of hot air in the door or in the door frame or one or more laterally disposed hot air outlets conceivable.
Der Warmlufteinlass der Tür und der Warmluftauslass der Tür können über eine oder mehrere Hohlkammern des Rahmens der Tür miteinander in Verbindung stehen.The hot air inlet of the door and the hot air outlet of the door may communicate with each other via one or more hollow chambers of the frame of the door.
Um den Luftstrom vorzugsweise beidseitig im Rahmen von dem Lufteinlass zu dem Luftauslass führen zu können, kann vorgesehen sein, dass die Tür ein Oberteil, ein Unterteil und zwei diese verbindenden Seitenteile aufweist und dass in einem oder in jedem der Seitenteile wenigstens eine der Hohlkammern vorgesehen ist. In einer solchen Ausgestaltung der Erfindung wird die oben in die Tür eingeführte Warmluft durch die beidseitig verlaufenden Hohlkammern des Rahmens zu dem vorzugsweise unten angeordneten Warmluftauslass geführt und gelangt von dort in geeigneter Weise in den Bereich der Scheibe.In order to be able to guide the air flow preferably on both sides in the frame from the air inlet to the air outlet, it can be provided that the door has an upper part, a lower part and two side parts connecting them and that at least one of the hollow chambers is provided in one or in each of the side parts , In such an embodiment of the invention, the hot air introduced into the top of the door is passed through the hollow chambers of the frame running on both sides to the hot air outlet, which is preferably arranged at the bottom, and passes from there into the area of the pane in a suitable manner.
Der Gerätekorpus kann wenigstens einen Luftauslass aufweisen, der relativ zu dem Lufteinlass der Tür bei geschlossener Tür derart angeordnet ist, dass die Warmluft von dem Luftauslass des Gerätekorpus zu dem Lufteinlass der Tür strömt. Dabei steht der Luftauslass des Gerätekorpus mit der Warmluftquelle, die wie oben ausgeführt beispielsweise durch den Kompressor, durch den Verflüssiger, etc. gebildet werden kann, in geeigneter Weise z. B. über einen Luftkanal etc. in Verbindung, so dass die dort gebildete Warmluft vorzugsweise mittels eines Gebläses zu dem Warmluftauslass des Gerätekorpus und von dort aus zu dem Warmlufteinlass der Tür geführt werden kann.The appliance body may include at least one air outlet disposed relative to the air inlet of the door with the door closed, such that the hot air flows from the air outlet of the appliance body to the air inlet of the door. In this case, the air outlet of the device body with the hot air source, which, as stated above, for example, by the compressor, by the condenser, etc., is suitably z. B. via an air duct, etc. in connection, so that the warm air formed there can preferably be guided by means of a blower to the hot air outlet of the device body and from there to the hot air inlet of the door.
Um einen Verlust von Warmluft möglichst zu verhindern, kann vorgesehen sein, dass eine Dichtung angeordnet ist, die den Übergang zwischen Luftauslass des Gerätekorpus und Lufteinlass der Tür wenigstens bei geschlossener Tür abdichtet.In order to prevent a loss of hot air as possible, it can be provided that a seal is arranged, which seals the transition between the air outlet of the device body and the air inlet of the door at least when the door is closed.
Da eine Restbetauung der Tür unter Umständen nicht ausgeschlossen werden kann, kann die Tür einen Kondenswasserablauf aufweisen. Denkbar ist es beispielsweise, im unteren Rahmenteil der Tür einen Kondenswasserablauf in Form einer Ausnehmung zu integrieren, um das in das Rahmenprofil eindringende Kondensat ablaufen zu lassen.Since residual dousing of the door can under some circumstances not be ruled out, the door may have a condensation drain. It is conceivable, for example, in the lower frame part of the door to integrate a condensate drain in the form of a recess to drain the penetrating into the frame profile condensate.
An dieser Stelle sei darauf hingewiesen, dass der Begriff "Tür" nicht auf ein um eine Vertikale verschwenkbares Verschlusselement beschränkt, sondern ebenfalls ein Verschlusselement umfasst, das um eine horizontal verlaufende Achse verschwenkbar ist, d. h. eine Klappe etc. Der Begriff "Tür" ist somit allgemein auszulegen und umfasst um eine vertikale Schwenkachse verschwenkbare Türen im eigentlichen Sinne sowie auch Klappen, verschiebbare Deckel etc. von Kühl- und/oder Gefriertruhen.It should be noted that the term "door" is not limited to a pivotable about a vertical closure element, but also includes a closure element which is pivotable about a horizontal axis, d. H. a flap etc. The term "door" is thus to be interpreted generally and includes pivotable about a vertical pivot axis doors in the true sense as well as flaps, sliding lid, etc. of refrigerators and / or freezers.

Der Rahmen 12 ist umlaufend an seiner zum Korpus gerichteten Seite mit einer Dichtung 13 versehen, wie dies ebenfalls aus
Durch die im oberen, horizontalen Rahmenteil 121 befindliche Lufteinlassöffnung 14 strömt Warmluft in den Rahmen 12, d. h. in das Hohlprofil des oberen Rahmenteils 121 ein und verteilt sich sodann über die Hohlprofile in den vertikalen Rahmenseitenteilen 123, 124. Von dort aus strömt die Warmluft in das untere, horizontale Rahmenteil 122. Dieses weist einen Luftauslass 16 auf, der derart angeordnet ist, dass die Warmluft, die aus dem Luftauslass 16 austritt, auf die Außenseite der außenliegenden Scheibe 21 geführt wird.Due to the air inlet opening 14 located in the upper,
Die Rahmenteile 121, 122, 123 und 124, die als Hohlprofile ausgeführt sind, dienen somit gleichzeitig als Luftkanäle und leiten den Luftstrom in dem hier dargestellten Beispiel beidseitig den Rahmen 12 hinunter. Der untere Teil 122 des Rahmens 12 kann beispielsweise als mehrteiliges oder einteiliges Spritzgußteil aufgebaut sein. Wie dies aus

Wie ausgeführt, beinhaltet der weitere Aufbau der Tür 10 ein Isolierglaspaket 20, eine Dichtung 13 und nicht näher dargestellte Scharniere zur Montage der Tür 10 an einem Kühlgerät. Des Weiteren weist die Tür einen aus
Durch eine geeignete Luftführung im Kühlgerät wird in dem hier dargestellten Ausführungsbeispiel die Abwärme von Verflüssiger und/oder vom Kompressor in den Lufteinlass 14 an der Türoberseite eingeblasen. Dabei kann zur besseren Funktion ein nicht dargestelltes Dichtelement eingesetzt werden, das den Lufteinlass 14 in geschlossenem Zustand der Tür voll bzw. teilweise umschließt. Diese Dichtung kann am Gerätekorpus angeordnet bzw. im Gerät integriert sein.By means of a suitable air duct in the cooling unit, the waste heat from the condenser and / or from the compressor is blown into the
Der Lufteinlass 14 steht zumindest bei geschlossener Tür mit einem nicht dargestellten Warmluftauslass des Gerätekorpus derart in Verbindung bzw. ist relativ zu diesem derart angeordnet, das die Warmluft aus dem Auslass des Gerätekorpus in den Lufteinlass 14 eindringen kann.At least when the door is closed, the
Der Luftstrom wird vorzugsweise mittig in die Tür 10 eingeblasen, um eine beidseitig symmetrische Beheizung des Rahmens 12 zu erhalten. Ein türmittiger Lufteinlass bzw. - auslass ist jedoch nicht zwingend erforderlich, da er sich nach den konstruktiven Randbedingungen bzw. nach der betauungskritischen Region richtet. Somit können auch nichtmittige Öffnungen bezüglich des Einlasses und Auslasses von Vorteil sein. Denkbar wäre somit beispielsweise auch, den Lufteinlass 14 und/oder den Luftauslass 16 alternativ oder zusätzlich in den weiteren Teilen 121, 122, 123, 124 des Rahmens 12 anzuordnen.The air flow is preferably injected centrally into the
Wie oben ausgeführt, wird die Luft über ein Hohlkammersystem im Rahmen 12 in Richtung des Luftauslasses 16 geleitet, der so ausgeführt ist, dass die Luft durch dessen Formgebung möglichst flächig und möglichst über die gesamte Scheibenbreite auf das Glas geblasen wird. Wie in
