Description

The invention relates to a device for drying a cloth containing a clammable filling, comprising a drum rotatable about an axis for receiving the textile piece and shaking the textile piece in an air stream passing through the drum.

Such a device is always from the EP 1 048 996 B1 . EP 1 098 028 B1 and the EP 1 108 812 B1 out. Each of these documents shows a corresponding device configured as a tumble dryer for use in a common household.

In particular, the invention relates to the drying of a textile article such as a blanket, a pillow, a jacket, a coat or a sleeping bag which is provided with a filling of down. Down has the property of inflating or thinning in the dry state, absorbing more of the air between its components. This air, in turn, causes a corresponding textile piece to be perceived as both soft and warming due to the insulating effect of the air taken up in this way. Instead of the down, a non-felted mass of artificially produced fibers, in particular hollow fibers, can occur.

It is in principle possible to wash such a piece of textile in a washing machine for a private household and then to dry in a corresponding conventional dryer. However, a filling of down or corresponding non-felted fibers tends to clump when moistened with water. Such lumps are difficult to re-dissolve in a conventional dryer, and water taken up in such lumps is difficult to remove. For this purpose it is known to add tennis balls or a sneaker made of fabric and rubber to a piece of textile to be dried in a conventional clothes dryer. During the drying process, during which the textile piece is shaken in the dryer is tapped, it is tapped by the additionally introduced objects, and thereby the lumps can be solved and the water absorbed therein be removed.

The invention is based on a task to find a technical design for a tumble dryer or the device mentioned above, which makes the drying of a piece of textile with a clunky filling a large circle of users and makes understandable; All necessary aids should be included in the tumble dryer or the device and be activated by an ordinary operator if necessary.

To solve this problem, a device is disclosed for drying a clotable filling contained textile piece, comprising a rotatable about an axis drum for receiving the textile piece and shaking of the textile piece in an air stream passing through the drum, wherein in the drum at least one knocker movable with the textile piece is attached to knock the textile piece during shaking.

The invention and preferred developments are also the subject of the present claims.

According to the invention, the apparatus described at the outset is supplemented by at least one component which can be activated and deactivated as required by an ordinary user and which causes the textile piece to knock to a satisfactory level for drying a textile piece with a clunkable filling.

The knocker is connected by a rope to the drum and otherwise freely movable in the drum. Preferably, the drum has a closable chamber for selectively receiving the knocker so that the knocker can be stowed in that chamber when it is not needed. Further preferably, this chamber is located in a driver for taking along the textile piece during rotation of the drum, or in a rear wall of the drum.

The problem is solved by an alternative embodiment of the invention, wherein the drum at least one driver for Take along the textile piece when rotating, and in which the knocker is a lever on the driver hingedly articulated. Preferably, this lever is selectively detectable on the driver.

Preferably, the drum has three or four drivers.

The knocker is preferably designed with a length between 150 mm and 200 mm, and in particular designed as a cylinder with rounded ends.

Preferably, the knocker has a diameter between 50 mm and 70 mm.

Also preferably, the knocker has a mass between 100 g and 200 g.

The provision of multiple knockers in the device may be advantageous to promote drying of the fabric.

The device is preferably designed as a tumble dryer, in particular for use in an ordinary household.

In general, the invention opens up the drying of a piece of textile with a clunky filling for an ordinary household. The means required for the purpose is an integral part of the device and, if its use is not required, can be fixed in the device captive and without compromising any further function of this device. This means is designed in its dimensions and in its mass so that a lumpy filling is loosened, but no damage to the treated textile piece and the filling occurs. It may be noted that a conventional fabric and rubber sneaker tends to be too heavy for this task, resulting in a risk of damage to the filling. A tennis ball is rather too easy for the task and therefore can fulfill the desired purpose at best imperfectly. Suitably, an elongate shape is the means for increasing, in its application, the likelihood of adequately tapping each clump in the filling.

In the application of this device for drying a piece of fabric with a clammable filling should be compared with a conventional Drying process reduced heating power can be used, so that the fabric surrounding the filling does not dry out excessively fast, whereby it becomes brittle and could be unduly stressed during the drying of the filling.

Each figure is to be understood as a sketch and only contains the significant elements for the following description of the device shown in each case. Under no circumstances should a representation be regarded as a true-to-scale reproduction.

Fig. 1 shows a sectional view of an apparatus for drying a textile piece 1, which contains a clottable filling 2, for example, down. The device comprises a drum 4 rotatable about an axis 3 with a cylindrical jacket 5 surrounding the axis 3 and a rear wall 6 aligned approximately perpendicularly to the axis 3. Not shown is an annular ring adjoining the casing 5 and pointing from there to the axis 3 Front wall of the drum 4, as provided in a conventional tumble dryer. Also, other components of such a tumble dryer, to which the device shown is not drawn for clarity; for relevant information, reference is made to the cited prior art documents. In the rear wall 6 are holes 7, of which in the present case only a smaller number can be seen. Through these holes 7 enters an air stream 8, symbolized by arrows, in the drum 4 and acts on laundry, which is located therein and is shaken by the rotation of the drum 4 about the axis 3 to assist the drying. To effect this shaking, 5 three drivers 9 are mounted inside the drum 4 and on the jacket. In the driver 9 shown below left is a Chamber 10, which is closed with a lid 11. In this chamber 10 is an optional removable knocker 12. To open the lid 11 this is provided with a handle hole 13; the lid 11 engages by conventional and not shown for clarity locking means in the driver 9 a. Another chamber 10 is provided in the rear wall 6; This is closed by means of a lid 11. To dry the textile piece 1 with the clammable filling 2, the knocker 12 is removed from the chamber 10, so that it is more or less freely movable in the drum 4 and in the rotation of the textile piece 1 and therein, partially clumped filling 2 knocks ,

Also in the rear wall 6 of the drum 4, a chamber 10 for receiving a knocker 12 is provided of the same shape and mass.

Fig. 2 shows a view of the driver 9 with removed knocker 12. The knocker 12 is elongated and has the shape of a cylinder with rounded ends; it has a length between 150 mm and 200 mm and a diameter between 50 mm and 70 mm, and a mass between 100 g and 200 g. With a rope 14, the knocker 12 is captively mounted in the drum 4. The cable 14 is anchored in the chamber 10 and is led out of the chamber 10 by a small recess 15 of the driver next to the lid 11.

Fig. 3 shows another embodiment of the device, wherein the device is only partially shown. Mounted on the jacket 5 is a driver 9, and on this driver 9 a knocker 16 in the form of a movable lever 16, which is articulated on a merely sketched joint 16 on the driver 9, is mounted. The lever 16 is freely movable in its function as a knocker 16 at least over a large angle 3 of almost 180 ° in order to knock a piece of textile 1 to be dried in the device with a foamable filling 2 and thereby loosen the filling 2. If the lever 16 is not to be used, it can be folded into the chamber 10 in the driver 9. To his fixation in this chamber 10, he has a detent hole 18, in which a provided in the driver 9 and in Fig. 3 only schematically indicated latch 19 engages.

It is understood that in each embodiment of the device a plurality of knockers 12 or 16 may be provided.

The presently presented apparatus for drying a garment containing a cleavable filling and the dryer having this device open up the drying for down-filled or similar textiles for a wide circle of users. All aids required for drying such textiles are included in the device.
