AEG Hausgeräte GmbH D-90429 NürnbergAEG Hausgeräte GmbH D-90429 Nuremberg
Die Neuerung bezieht sich auf einen Haushalt-Wäschetrockner mit einem in einem Gehäuse untergebrachten luftgekühlten Wärmetauscher zum Kondensieren der in die Prozeßluft übertragenen Wäschefeuchtigkeit, wobei das im Wärmetauscher kondensierte Wasser in ein Auffanggefäß tropft bzw. abläuft.The innovation relates to a household tumble dryer with an air-cooled heat exchanger housed in a housing for condensing the laundry moisture transferred into the process air, with the water condensed in the heat exchanger dripping or running off into a collecting vessel.
Bei einem solchen Wäschetrockner gelangt die mit Feuchtigkeit angereicherte Prozeßluft nach dem Verlassen der Wäschetrommel über einen Luftfilter in einen Wärmetauscher (Kondensator). Im Wärmetauscher wird die der Wäsche entzogene Feuchtigkeit kondensiert. Die Kondensation wird durch Luftkühlung des Wärmetauschers erreicht. Der Wärmetauscher besteht in der Regel aus mehrere gut wärmeleitende, flache Hohlräume umschließende Platten, deren mit wellenförmig gefalteten Rippenblechen ausgefüllte Hohlräume von der Kühlluft und deren zwischen sich gebildete Hohlräume von der Prozeßluft im wesentlichen quer zur Kühlluft durchströmt werden. Das kondensierte Wasser gelangt in einen Auffangbehälter und wird von dort in einen herausziehbaren Kondensat-Sammelbehälter gepumpt. Der Wärmetauscher im Wäschetrockner ist in einer horizontalen Ebene angeordnet.In such a tumble dryer, the moisture-enriched process air passes through an air filter into a heat exchanger (condenser) after leaving the laundry drum. The moisture extracted from the laundry is condensed in the heat exchanger. Condensation is achieved by air cooling the heat exchanger. The heat exchanger usually consists of several plates with good heat conductivity, enclosing flat cavities, the cavities of which are filled with corrugated folded ribbed plates through which the cooling air flows, and the cavities formed between them through which the process air flows, essentially perpendicular to the cooling air. The condensed water reaches a collecting container and is pumped from there into a pull-out condensate collection container. The heat exchanger in the tumble dryer is arranged in a horizontal plane.
Ausgehend von diesem Stand der Technik liegt der Neuerung die Aufgabe zugrunde, das Ablaufen des Kondensats aus dem Wärmetauscher zu beschleunigen.Based on this state of the art, the innovation is based on the task of accelerating the drainage of condensate from the heat exchanger.
Die Lösung dieser Aufgabe gemäß der Neuerung besteht darin, daß der Wärmetauscher gegenüber der Horizontalen in Richtung der Kühlluftströmung um einen Winkel &agr; geneigt verlaufend angeordnet ist. Durch die vorgeschlagene Maßnahme ergibt sich eine günstige Ableitung und ein stetiger Ablauf des kondensierenden Wassers aus dem Wärmetauscher und damit eine wesentliche Verbesserung des Wirkungsgrades.The solution to this problem according to the innovation is that the heat exchanger is arranged at an angle α to the horizontal in the direction of the cooling air flow. The proposed measure results in a favorable drainage and a continuous flow of the condensing water from the heat exchanger and thus a significant improvement in efficiency.
Ein Ausführungsbeispiel der Neuerung ist in der Zeichnung dargestellt und wird anhand dieser nachfolgend näher beschrieben.An example of the innovation is shown in the drawing and is described in more detail below.
Die Zeichnung zeigt einen sogenannten Kondensationswäschetrockner in schematischer Darstellung und einen Wärmetauscher in vergrößerter-Einzeldarstellung.The drawing shows a so-called condensation dryer in a schematic representation and a heat exchanger in an enlarged individual representation.
Der Kondensationswäschetrockner hat eine, übliche Wäschetrommel 1 und einen zu einem Wärmetauscher 2 (Kondensator) führenden Luftschacht 3, durch den mit Feuchtigkeit angereicherte Prozeßluft aus der Wäschetrommel in den Wärmetauscher 2 geleitet wird. Der Wärmetauscher 2 besteht aus einem System von flachen Kanälen 4 und 5, die jeweils um 90 Winkelgrade versetzt - von der Prozeßluft (Kanäle 4) bzw. der Kühlluft (Kanäle 5) durchströmt werden. Die Kontaktfläche soll dabei möglichst groß sein, damit eine intensive Kondensation erreicht wird. Das kondensierte Wasser tropft in ein Auffanggefäß. Um nun die Ableitung des im Wärmetauscher 2 anfallenden Kondensats zu verbessern, ist der Wärmetauscher 2 im Gehäuse gegenüber der Horizontalen X in Richtung der Kühlluftströmung zweckmäßig um einen Winkel &agr; geneigt verlaufend angeordnet. Der Wärmetauscher 2 ist dabei schräg nach unten geneigt im Wäschetrockner-Gehäuse untergebracht.The condensation tumble dryer has a standard laundry drum 1 and an air shaft 3 leading to a heat exchanger 2 (condenser), through which moisture-enriched process air from the laundry drum is led into the heat exchanger 2. The heat exchanger 2 consists of a system of flat channels 4 and 5, each of which is offset by 90 degrees - through which the process air (channels 4) and the cooling air (channels 5) flow. The contact surface should be as large as possible so that intensive condensation is achieved. The condensed water drips into a collecting vessel. In order to improve the drainage of the condensate accumulating in the heat exchanger 2, the heat exchanger 2 is arranged in the housing at an angle α relative to the horizontal X in the direction of the cooling air flow. The heat exchanger 2 is housed in the tumble dryer housing at an angle α.
