Description

Die Erfindung betrifft ein Haushaltgerät zur Pflege von Wäschestücken, insbesondere Wäschetrockner, mit einem eine Rückseite bildenden Wandbereich und einer an dem Wandbereich angeordneten Luftführungsvorrichtung, welche einen Strömungskanal mit zwei gegenüberliegenden offenen Endbereichen aufweist, wobei ein erster offener Endbereich mit einer Heizungsvorrichtung und ein zweiter offener Endbereich mit einer Lüftervorrichtung verbunden ist, wobei die Lüftervorrichtung ein Lüfterrad aufweist, das in einem Gehäuse angeordnet ist, welches eine Öffnung aufweist, die in den zweiten offenen Endbereich mündet.
[001a] Ein solches Haushaltgerät in Form eines Wäschetrockners geht hervor aus der EP 0 576 825 A1 . Ein Haushaltgerät in Form eines Wäschetrockners, bei dem im Unterschied zum Haushaltgerät der eingangs genannten Art die Lüftervorrichtung nicht an einem eine Rückwand bildenden Wandbereich angeordnet ist, sondern an einem Rahmenteil innerhalb des Haushaltgeräts, geht hervor aus der GB 1 510 049 . Ein Haushaltgerät in Form eines Wäschetrockners, bei dem im Unterschied zum Haushaltgerät der eingangs genannten Art die Luftführungsvorrichtung nicht an einem Wandbereich angeordnet ist, geht hervor aus dem US-Patent 4,468,867 .The invention relates to a domestic appliance for the care of laundry items, in particular tumble dryer, having a rear wall forming wall portion and an air guide device disposed on the wall region, which has a flow channel with two opposite open end portions, wherein a first open end portion with a heating device and a second open end portion is connected to a fan device, wherein the fan device comprises a fan wheel, which is arranged in a housing having an opening which opens into the second open end region.
[001a] Such a household appliance in the form of a tumble dryer is apparent from the EP 0 576 825 A1 , A domestic appliance in the form of a tumble dryer, in which, in contrast to the household appliance of the type mentioned, the fan device is not arranged on a wall forming a rear wall area, but on a frame part within the household appliance, it is clear from the GB 1 510 049 , A domestic appliance in the form of a tumble dryer, in which, in contrast to the household appliance of the type mentioned, the air guiding device is not arranged on a wall area, it is apparent from the U.S. Patent 4,468,867 ,

Beim Betrieb dieser bekannten Wäschetrockner treten relativ hohe Energieverluste insbesondere an Metallteilen des Wäschetrockners auf. Dadurch wird der Energieverbrauch derartiger Haushaltwäschetrockner oftmals deutlich erhöht. Darüber hinaus werden über große Metallflächen des Haushaltwäschetrockners Luftführungsgeräusche abgestrahlt, wodurch eine erhebliche Geräuschentwicklung entsteht. Des Weiteren ist bei den bekannten Haushaltwäschetrocknern ein Nachteil darin zu sehen, dass oftmals relativ lange Trocknungszeiten gegeben sind, welche auch durch die unzureichende Luftführung bedingt wird.During operation of these known clothes dryers, relatively high energy losses occur, in particular on metal parts of the tumble dryer. As a result, the energy consumption of such household laundry dryer is often significantly increased. In addition, air ducting noise is radiated over large metal surfaces of the household clothes dryer, resulting in a significant noise. Furthermore, it is a disadvantage in the known household laundry driers to see that often relatively long drying times are given, which is also due to the insufficient air flow.

Daher ist es Aufgabe der vorliegenden Erfindung, ein Haushaltgerät zur Pflege von Wäschestücken zu schaffen, welches einen reduzierten Energieverbrauch und darüber hinaus eine relativ geringe Geräuschentwicklung während des Betriebs aufweist. Insbesondere ist es Aufgabe der vorliegenden Erfindung, einen Wäschetrockner zu schaffen, welcher neben einem geringen Energieverbrauch und eines leisen Betriebs auch eine Reduzierung der Trocknungszeit gewährleisten kann.Therefore, it is an object of the present invention to provide a household appliance for the care of laundry, which has a reduced energy consumption and, moreover, a relatively low noise during operation. In particular, it is an object of the present invention to provide a clothes dryer, which can ensure a reduction of the drying time in addition to low energy consumption and quiet operation.

Diese Aufgabe wird durch ein Haushaltgerät zur Pflege von Wäschestücken, welches die Merkmale nach Patentanspruch 1 aufweist, gelöst.This object is achieved by a household appliance for the care of items of laundry, which has the features of claim 1.

Ein erfindungsgemäßes Haushaltgerät zur Pflege von Wäschestücken, insbesondere Wäschetrockner, mit einem eine Rückseite bildenden Wandbereich und einer an dem Wandbereich angeordneten Luftführungsvorrichtung, welche einen Strömungskanal mit zwei gegenüberliegenden offenen Endbereichen aufweist, wobei ein erster offener Endbereich mit einer Heizungsvorrichtung und ein zweiter offener Endbereich mit einer Lüftervorrichtung verbunden ist, wobei die Lüftervorrichtung ein Lüfterrad aufweist, das in einem Gehäuse angeordnet ist, welches eine Öffnung aufweist, die in den zweiten offenen Endbereich mündet, zeichnet sich dadurch aus, dass das Gehäuse mit einem separaten Deckel abgedeckt ist, und das Gehäuse und der Strömungskanal von einer Abdeckung abgedeckt sind, wobei der Deckel zwischen der Lüftervorrichtung und der Abdeckung angeordnet ist.An inventive household appliance for the care of laundry, in particular tumble dryer, having a rear wall forming wall portion and arranged on the wall portion air ducting device having a flow channel with two opposite open end portions, wherein a first open end portion with a heating device and a second open end portion with a Fan device is connected, wherein the fan device comprises a fan wheel, which is arranged in a housing having an opening which opens into the second open end region, is characterized in that the housing is covered with a separate lid, and the housing and the flow channel are covered by a cover, wherein the lid between the fan device and the cover is arranged.

Ein wesentlicher Gedanke der Erfindung besteht darin, dass zumindest die Lüftervorrichtung im vom Haushaltgerät abgewandten Bereich doppelwandig abgedeckt ist. Durch eine derartig doppelwandige Abdeckung der Lüftervorrichtung an der Außenseite der Lüftervorrichtung kann eine wesentlich verbesserte Isolationswirkung erreicht werden. Des Weiteren kann dadurch der Energieverbrauch des erfindungsgemäßen Haushaltgeräts reduziert werden und insbesondere dann, wenn das erfindungsgemäße Haushaltgerät als Wäschetrockner ausgebildet ist, auch eine Trocknungszeit von in dem Wäschetrockner zu pflegenden Wäschestücken reduziert werden.An essential idea of the invention is that at least the fan device is covered in a double-walled manner in the area facing away from the household appliance. By such a double-walled cover of the fan device on the outside of the fan device, a significantly improved insulation effect can be achieved. Furthermore, the energy consumption of the domestic appliance according to the invention can thereby be reduced and, in particular, when the household appliance according to the invention is designed as a tumble dryer, also a drying time of laundry items to be cared for in the tumble dryer can be reduced.

Erfindungsgemäß ist das doppelwandige Abdecken der Lüftervorrichtung durch die Abdeckung und einen zusätzlichen separaten Deckel, welcher zwischen der Lüftervorrichtung und der Abdeckung angeordnet ist, ausgebildet. Die Lüftervorrichtung ist somit im vom Haushaltgerät abgewandten Bereich durch zwei separate Elemente abgedeckt, wobei diese beiden Elemente zur Abdeckung der Lüftervorrichtung ineinander geführt sind, wodurch auch eine sehr platzsparende Ausbildung erreicht werden kann.According to the invention, the double-walled covering of the fan device is formed by the cover and an additional separate cover, which is arranged between the fan device and the cover. The fan device is thus covered in the area facing away from the household appliance by two separate elements, these two elements are performed to cover the fan device into each other, whereby a very space-saving training can be achieved.

Der zusätzliche separate Deckel ist in bevorzugter Weise aus Kunststoff ausgebildet. Dadurch kann erreicht werden, dass die Anzahl der Metallflächen in dem Haushaltgerät reduziert werden und der separate Deckel relativ leicht hergestellt werden kann.The additional separate lid is preferably made of plastic. It can thereby be achieved that the number of metal surfaces in the household appliance can be reduced and the separate lid can be produced relatively easily.

Die Luftführungsvorrichtung weist in bevorzugter Weise einen geschlossenen Strömungskanal mit offenen Endbereichen auf, wobei der geschlossene Strömungskanal bevorzugt zweiteilig ausgebildet ist und durch einen, der Außenseite des Haushaltgeräts zugewandten Wandbereich der Rückseite des Haushaltgeräts und einem an diesem Wandbereich angeordneten, im Querschnitt U-förmig geformten Element, ausgebildet ist. Dies ermöglicht eine sehr effektive und effiziente Luftführung zwischen der Lüftervorrichtung und einer Heizungsvorrichtung, welche an einem offenen Endbereich der Luftführungsvorrichtung angeschlossen sein kann. Auch durch einen derartig geschlossenen Strömungskanal kann erreicht werden, dass der Energieverbrauch des Haushaltgeräts nochmals reduziert wird und des Weiteren die Trocknungszeit von in dem Haushaltgerät zu pflegenden Wäschestücken nochmals vermindert werden kann.The air guiding device preferably has a closed flow channel with open end regions, wherein the closed flow channel is preferably formed in two parts and by one, the outside of the appliance facing wall portion of the back of the household appliance and arranged on this wall area, in cross-section U-shaped element , is trained. This allows a very effective and efficient air flow between the fan device and a heating device, which may be connected to an open end portion of the air guide device. Also by such a closed flow channel can be achieved that the energy consumption of the household appliance is further reduced and further the drying time of the household appliance to be cared for laundry items can be further reduced.

Die Lüftervorrichtung und die Heizungsvorrichtung sind in vorteilhafter Weise mit der Luftführungsvorrichtung verbunden, wobei die Heizungsvorrichtung mit dem ersten offenen Endbereich und die Lüftervorrichtung mit dem zweiten offenen Endbereich des geschlossenen Strömungskanals verbunden sein kann.The fan device and the heating device are advantageously connected to the air guiding device, wherein the heating device may be connected to the first open end region and the fan device to the second open end region of the closed flow channel.

Die Lüftervorrichtung weist in vorteilhafter Weise ein Lüfterrad auf, wobei das Lüfterrad in einem Gehäuse angeordnet ist, welches eine Öffnung aufweist, die in den zweiten offenen Endbereich des geschlossenen Strömungskanals mündet. Die Luftführung von der Lüftervorrichtung, insbesondere vom Lüfterrad über den geschlossenen Strömungskanal hin zur Heizungsvorrichtung und von dieser in eine Trommel des erfindungsgemäßen Haushaltgeräts, in dem die Wäschestücke zur Pflege enthalten sind, kann dadurch optimiert werden.The fan device advantageously has a fan wheel, wherein the fan wheel is arranged in a housing which has an opening which opens into the second open end area of the closed flow channel. The air flow from the fan device, in particular from the fan wheel via the closed flow channel to the heating device and from this into a drum of the household appliance according to the invention, in which the laundry items are included for the care can be optimized thereby.

Weitere vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen angegeben, die gemäß der Erfindung in beliebiger Weise miteinander kombinierbar sind.Further advantageous embodiments of the invention are specified in the subclaims, which can be combined according to the invention in any desired manner.
