Description
Die vorliegende Erfindung betrifft einen Abtauwasserkanal eines Kühlgerätes, insbesondere eines NoFrost Kühlgerätes sowie ein Kühlgerät, insbesondere ein NoFrost Kühlgerät.The present invention relates to a Abtauwasserkanal a cooling device, in particular a NoFrost cooling device and a cooling device, in particular a NoFrost cooling device.
Bei einem Kühlgerät der genannten Art wird die Luft mittels einem Umluftsystem im Kühlraum einem Verdampfer, der insbesondere außerhalb des eigentlichen Kühlraums angeordnet ist, zugeführt. An dem Verdampfer bildet sich Eis. Der Verdampfer taut regelmäßig ab, wobei das Abtauwasser über einen Abtauwasserkanal abgeführt wird. Um ein Einströmen von Umgebungsluft über den Abtauwasserkanal in den Kühlraum bzw. im Falle eines Nofrost-Geräts in den Verdampferraum zu verhindern, ist in den Abtauwasserkanal z.B. ein Siphon integriert. Nachteilig ist, dass insbesondere bereits vor Inbetriebnahme des Kühlgerätes, bzw. bis zu dem Zeitpunkt bis der Siphon mit Wasser gefüllt ist, Umgebungsluft und -Feuchtigkeit durch den Abtauwasserkanal in den Kühlraum bzw. zum Verdampfer strömen und den Verdampfer vereisen kann. Herkömmlich wird dies häufig durch eine Membran verhindert, die den Eintritt der Umgebungsluft und -Feuchtigkeit einseitig verhindert und andererseits das Abfließen des Abtauwassers ermöglicht. Nachteilig ist weiterhin, dass eine solche Membran häufig eine Struktur aufweist, die für ein biologisches Zuwachsen anfällig ist.In a cooling device of the type mentioned, the air is supplied by means of a circulating air system in the cooling chamber to an evaporator, which is arranged in particular outside the actual cooling space. Ice forms on the evaporator. The evaporator thaws regularly, the defrost water is discharged through a Abtauwasserkanal. In order to prevent the inflow of ambient air into the evaporator space via the defrosting water channel or, in the case of a Nofrost apparatus, into the evaporator space, the defrosting water channel can be filled with e.g. integrated a siphon. The disadvantage is that in particular already before starting the refrigerator, or until the time until the siphon is filled with water, ambient air and moisture can flow through the Abtauwasserkanal in the refrigerator or to the evaporator and can freeze the evaporator. Conventionally, this is often prevented by a membrane that prevents the entry of ambient air and moisture on one side and on the other hand allows the flow of defrost water. A further disadvantage is that such a membrane often has a structure that is prone to biological growth.
Aufgabe der Erfindung ist es daher, ein Zuströmen von Umgebungsluft durch einen Abtauwasserkanal zu einem Verdampfer eines Kühlgerätes, unter Vermeidung der Nachteile des Standes der Technik, zu verhindern, wobei das biologische Wachstum verringert oder sogar unterbunden wird, und zusätzlich das Anschließen eines Kühlgerätes einfach und kostengünstig zu ermöglichen, und die Montage der Einzelteile besonders einfach und kostengünstig erfolgt. Die Umweltverträglichkeit soll zudem verbessert werden.The object of the invention is therefore to prevent an influx of ambient air through a Abtauwasserkanal to an evaporator of a refrigerator, while avoiding the disadvantages of the prior art, wherein the biological growth is reduced or even prevented, and in addition the connection of a Cooler easy and inexpensive to allow, and the assembly of items is particularly simple and inexpensive. The environmental compatibility should also be improved.
Die Aufgabe wird gelöst mit einem Abtauwasserkanal eines Kühlgerätes, insbesondere eines NoFrost-Kühlgerätes, mit einem wasserlöslichen Kanalverschlussmittel, welches als Folie, insbesondere Stärkefolie ausgebildet ist.The object is achieved with a Abtauwasserkanal a cooling device, in particular a NoFrost cooling device, with a water-soluble channel closure means, which is designed as a film, in particular starch foil.
Ein Kühlgerät im Sinne der Erfindung ist insbesondere automatisch abtaubar und beispielsweise ein Kühlschrank, ein Gefrierschrank oder eine Kühl- Gefrierkombination oder eine Gefriertruhe. Ein NoFrost Kühlgerät im Sinne der Erfindung ist ein Kühlgerät bei welchem der Verdampfer außerhalb des Kühlfaches in einem Verdampferfach angeordnet, und die Kühlluft über Kühlluftkanäle anhand eines Ventilators zwischen Verdampferfach und Kühlfächern umgewälzt wird. Der Verdampfer eines solchen Kühlgeräts ist durch eine Abtauheizung abtaubar.A cooling device according to the invention is in particular automatically defrostable and, for example, a refrigerator, a freezer or a fridge-freezer or a freezer. A NoFrost cooling device according to the invention is a cooling device in which the evaporator outside the cooling compartment in an evaporator compartment, and the cooling air is circulated via cooling air ducts using a fan between evaporator compartment and cooling compartments. The evaporator of such a refrigerator can be defrosted by a defrost heater.
Um ein Einströmen von Umgebungsluft über den Abtauwasserkanal in den Kühlraum bzw. im Falle eines Nofrost-Geräts in den Verdampferraum zu verhindern, ist in den Abtauwasserkanal ein Siphon integriert.In order to prevent an influx of ambient air through the Abtauwasserkanal in the refrigerator or in the case of a Nofrost device in the evaporator chamber, a siphon is integrated in the Abtauwasserkanal.
Der Abtauwasserkanal des Kühlgerätes transportiert im Kühlgerät insbesondere am Verdampfer entstehendes Abtauwasser nach außerhalb des Kühlgerätes, so dass das Abtauwasser außerhalb des Kühlgerätes, insbesondere unter Ausnutzung der Abwärme eines Kompressors, verdampfen kann. Der Abtauwasserkanal ist beispielsweise ein Rohr, ein Schlauch oder eine Rinne.The Abtauwasserkanal the cooling unit transported in the refrigerator, in particular at the evaporator resulting defrost water outside the refrigerator, so that the defrost water outside the refrigerator, in particular by utilizing the waste heat of a compressor, can evaporate. The Abtauwasserkanal is for example a pipe, a hose or a gutter.
Ein erfindungsgemäßes Kanalverschlussmittel löst sich durch den Kontakt mit Wasser auf, insbesondere durch den Kontakt mit Abtauwasser eines Kühlgerätes. Es dichtet den Abtauwasserkanal eines Kühlgerätes daher zeitweise ab, so dass keine Umgebungsluft und -Feuchtigkeit den Abtauwasserkanal durchströmen kann, und zwar solange, bis es sich durch den Kontakt mit Wasser auflöst. Mit dem Kanalverschlussmittel ist der Abtauwasserkanal daher zumindest teilweise verschließbar. Da sich das Kanalverschlussmittel durch Kontakt mit Wasser auflöst, besteht im Betrieb des Kühlgerätes gar nicht die Gefahr, dass es biologisch zuwächst.An inventive channel closure means dissolves by contact with water, in particular by the contact with defrost water of a cooling device. It therefore seals the Abtauwasserkanal a cooling device from time to time, so that no ambient air and moisture can flow through the Abtauwasserkanal, and that until it dissolves due to contact with water. With the channel closure means the Abtauwasserkanal is therefore at least partially closed. Since the channel sealant dissolves on contact with water, the operation of the refrigerator is not at risk of biologically increasing.
Bei dem erfindungsgemäßen Abtauwasserkanal ist das Kanalverschlussmittel als Folie, insbesondere als Stärkefolie, ausgebildet. Eine solche Folie ist kostengünstig herstellbar und ermöglicht eine optimale Anpassung des Verschlussmittels an die Geometrie des Querschnitts des Abtauwasserkanals. Stärkefolie ist zusätzlich umweltfreundlich abbaubar. Es eignen sich aber auch beliebig andere Kanalverschlussmittel, mit denen der Abtauwasserkanal zeitweise verschließbar ist. Beispielsweise eignen sich die Pfropfen oder ein Platte, deren Geometrie an den Querschnitt des Abtauwasserkanals so angepasst ist, dass der Abtauwasserkanal mit ihnen verschließbar ist und die aus einem beliebigen wasserlöslichen Material gefertigt sind.In the defrost water channel according to the invention, the channel closure means is formed as a film, in particular as a starch film. Such a film is inexpensive to produce and allows optimal adaptation of the closure means to the geometry of the cross section of the Abtauwasserkanals. Starch foil is also environmentally friendly degradable. But there are also any other channel closure means with which the Abtauwasserkanal is temporarily closed. For example, the plug or a plate whose geometry is adapted to the cross section of the Abtauwasserkanals so that the Abtauwasserkanal is closed with them and are made of any water-soluble material.
Vorzugsweise umfasst das Kanalverschlussmittel eine Substanz, die biologisches Wachstum verhindert, beispielsweise ein Salz, Gel oder eine Flüssigkeit. Dadurch kann, insbesondere wenn das Kanalverschlussmittel nach dem Auflösen im Wasser ein biologisches Wachstum fördert, ein solches Wachstum durch die Substanz verringert oder sogar vermieden werden. Da das Kanalverschlussmittel die Substanz umfasst, wird die Substanz erst aktiviert, wenn das biologische Wachstum aufgrund des sich auflösenden Kanalverschlussmittels tatsächlich verhindert werden muss. Das Kanalverschlussmittel umfasst die Substanz beispielsweise in Tablettenform, wobei die Tabletten beispielsweise im Kanalverschlussmittel eingeschweißt sind, oder sie ist in jedweder anderen Form im Kanalverschlussmittel integriert. Die Substanz ist besonders bevorzugt wasserlöslich, so dass sie mit dem Wasser abführbar ist.Preferably, the channel closure means comprises a substance which prevents biological growth, for example a salt, gel or liquid. Thereby, especially if the channel closure agent promotes biological growth after dissolution in the water, such growth can be reduced or even avoided by the substance. Since the channel closure agent comprises the substance, the substance is activated only if the biological growth due to the dissolving channel closure agent actually has to be prevented. The channel closure means comprises the substance, for example in tablet form, wherein the tablets are, for example, sealed in the channel closure means, or it is integrated in the channel closure means in any other form. The substance is particularly preferably water-soluble, so that it can be discharged with the water.
Das Kanalverschlussmittel kann auch einen Compositeaufbau aufweisen, wobei beispielsweise die Substanz einen Teil des Kanalverschlussmittels bildet.The channel closure means may also have a composite structure, wherein, for example, the substance forms part of the channel closure means.
Weiterhin bevorzugt ist die Substanz getrennt von der Folie im Abtauwasserkanal vorgesehen, beispielsweise in Fließrichtung des Abtauwassers vor und/oder hinter der Folie und/oder zusätzlich in die Folie integriert. Ebenso bevorzugt bildet die Substanz das Kanalverschlussmittel oder sie ist ein zusätzliches den Abtauwasserkanal zeitweise verschließendes Kanalverschlussmittel.Further preferably, the substance is provided separately from the film in the Abtauwasserkanal, for example, in the flow direction of the defrost water before and / or behind the film and / or additionally integrated into the film. Also preferably, the substance forms the channel closure means or it is an additional channel closure means temporarily occluding the defrost water channel.
Die Aufgabe wird weiterhin gelöst mit einem Abtauwasserkanal eines Kühlgerätes, wobei der Abtauwasserkanal ein erfindungsgemäßes Kanalverschlussmittel zum Verschließen des Abtauwasserkanals umfasst. Ein solcher Abtauwasserkanal ist mit dem Kanalverschlussmittel verschlossen, bis dieses mit Wasser in Kontakt gerät und sich dadurch auflöst. Sobald sich das Kanalverschlussmittel auflöst, kann der Abtauwasserkanal vom Abtauwasser durchflossen werden und nach außerhalb des Kühlgerätes abfließen.The object is also achieved with a Abtauwasserkanal a cooling device, wherein the Abtauwasserkanal comprises a channel closure means according to the invention for closing the Abtauwasserkanals. Such Abtauwasserkanal is closed with the channel closure means until it comes into contact with water and thereby dissolves. As soon as the sewer sealer dissolves, the defrost water channel can be drained by the defrost water and discharged to the outside of the cooling unit.
Bevorzugt ist das Kanalverschlussmittel im Abtauwasserkanal im wesentlichen quer zur Fließrichtung des Abtauwassers angeordnet. Dabei ist die Außengeometrie des Kanalverschlussmittels im wesentlichen kongruent der Innengeometrie des Abtauwasserkanals, so dass das Kanalverschlussmittel den Abtauwasserkanal zuverlässig abdichtet, solange es sich nicht durch den Kontakt mit Wasser auflöst. Die Größe des benötigten Kanalverschlussmittels ist daher im Wesentlichen durch die Größe des Abtauwasserkanals bestimmt, so dass das Kanalverschlussmittel klein und kostengünstig gestaltbar ist. Es kommen beliebige Querschnitte für den Abtauwasserkanal in Betracht, bevorzugt sind jedoch ein runder, viereckiger oder ovaler Querschnitt.Preferably, the channel closure means is arranged in Abtauwasserkanal substantially transverse to the flow direction of the defrost water. The outer geometry of the channel closure means is substantially congruent to the internal geometry of the Abtauwasserkanals, so that the channel closure means reliably seals the Abtauwasserkanal as long as it does not dissolve through contact with water. The size of the The required channel closure means is therefore determined essentially by the size of the Abtauwasserkanals, so that the channel closure means is small and inexpensive gestaltungsbar. There are any cross-sections for the Abtauwasserkanal into consideration, but preferred are a round, square or oval cross-section.
Vorzugsweise umfasst der Abtauwasserkanal einen Siphon, wobei das Kanalverschlussmittel in Fließrichtung des Abtauwassers hinter dem Siphon angeordnet ist. Beim Enteisen des Verdampfers des Kühlgerätes wird daher zuerst der Siphon mit Abtauwasser gefüllt. Erst danach gerät das Kanalverschlussmittel in Kontakt mit dem Wasser und löst sich auf. Da der Siphon bereits mit Abtauwasser gefüllt ist, kann auch nach dem Auflösen des Kanalverschlussmittels keine Umgebungsluft mehr durch den Abtauwasserkanal zum Verdampfer fließen. Besonders bevorzugt ist das Kanalverschlussmittel so im Abtauwasserkanal angeordnet, dass es sich vollständig auflöst, beispielsweise indem es entlang seiner gesamten dem Wasser zugewandten Fläche mit dem Wasser in Kontakt gerät.Preferably, the Abtauwasserkanal comprises a siphon, wherein the channel closure means is arranged in the flow direction of the defrost water behind the siphon. When defrosting the evaporator of the refrigerator, therefore, the siphon is first filled with defrost water. Only then does the channel closure come into contact with the water and dissolve. Since the siphon is already filled with defrost water, no ambient air can flow through the Abtauwasserkanal to the evaporator even after the dissolution of the channel closure means. Particularly preferably, the channel closure means is arranged in the Abtauwasserkanal that it dissolves completely, for example by it comes along its entire water-facing surface with the water in contact.
Weiterhin bevorzugt ist die Substanz zur Verhinderung des biologischen Wachstums insbesondere zusätzlich in Fließrichtung des Abtauwassers vor dem Siphon angeordnet. Die Substanz kann beispielsweise in Tablettenform oder in jedweder anderen Form im Abtauwasserkanal angeordnet sein, beispielsweise als Salz, Gel oder Flüssigkeit und beispielsweise in Form eines Päckchens. Alternativ oder zusätzlich kann das Kanalverschlussmittel ebenfalls die Substanz umfassen.Furthermore, the substance for preventing the biological growth is preferably additionally arranged upstream of the siphon in the direction of flow of the defrosting water. The substance can be arranged, for example, in tablet form or in any other form in the defrost water channel, for example as salt, gel or liquid and, for example, in the form of a packet. Alternatively or additionally, the channel closure means may also comprise the substance.
Die Aufgabe wird weiterhin gelöst mit einem Kühlgerät, insbesondere einem NoFrost Kühlgerät, wobei das Kühlgerät einen erfindungsgemäßen Abtauwasserkanal umfasst. Bei einem solchen Kühlgerät ist ein kritisches Abtauen des Verdampfers und des Abtauwasserkanals vor Inbetriebnahme des Kühlgerätes unnötig, da keine Umgebungsluft und auch keine Feuchtigkeit durch den Abtauwasserkanal zum Verdampfer strömen kann. Das Anschließen des Kühlgerätes ist daher einfach und kostengünstig.The object is also achieved with a cooling device, in particular a NoFrost cooling device, wherein the cooling device comprises a Abtauwasserkanal invention. In such a cooling device, a critical defrosting of the evaporator and Abtauwasserkanals before commissioning of the refrigerator is unnecessary because no ambient air and no moisture can flow through the Abtauwasserkanal to the evaporator. Connecting the refrigerator is therefore easy and inexpensive.
Bei dem Kühlgerät besteht auch die Gefahr eines Zuwachsens einer einseitig luftundurchlässigen Membran gar nicht, da das Kanalverschlussmittel sich auflöst, sobald es in Kontakt mit Wasser gerät. Sofern das Kanalverschlussmittel selbst das biologische Wachstum fördert, wird dies verhindert, indem im Abtauwasserkanal und/oder im Kanalverschlussmittel selbst eine das biologische Wachstum verhindernde Substanz angeordnet wird bzw. umfasst ist. Die im Kanalverschlussmittel umfasste Substanz wird erst zu dem Zeitpunkt aktiviert, wenn sich das Kanalverschlussmittel auflöst. Eine Aktivierung während der Lagerung des Kühlgerätes oder seinem Transport wird daher sicher vermieden, so dass die das biologische Wachstum verhindernde Wirkung sicher bis zum Auflösezeitpunkt des Kanalverschlussmittels erhalten bleibt.In the refrigerator there is also the risk of growth of a one-sided air-impermeable membrane not at all, since the channel closure means dissolves when it comes into contact with water. If the channel closure agent itself promotes biological growth, this is prevented by the Abtauwasserkanal and / or in the Channel closure means even a biological growth-preventing substance is arranged or is included. The substance contained in the channel closure means is activated only at the time when the channel closure means dissolves. Activation during storage of the refrigerator or its transport is therefore safely avoided, so that the biological growth preventing effect is safely maintained until the dissolution time of the channel closure means.
