Abstract
Description
Die Erfindung betrifft ein Waschmaschine mit einem Laugenbehälter, in dem eine zylinder förmige Trommel zur Aufnahme von Waschgut drehbar gelagert ist, wobei der Mantel der Trommel Löcher zum Durchtritt von Wasch-/Spülflüssigkeit besitzt und wobei am Mantel ins Trommelinnere ragende Mitnehmer angeordnet sind.The invention relates to a washing machine with a tub, in which a cylinder shaped drum for receiving laundry is rotatably supported, the jacket of the Drum has holes for the passage of washing / rinsing liquid and in the jacket Protruding drivers inside the drum are arranged.
Bei Waschmaschinen ist es üblich, den Trommelmantel und evtl. auch die Deckflächen mit Löchern zu versehen, damit ein Laugenaustausch zwischen Wäsche und Laugenbehälter gewährleistet ist. Diese Löcher besitzen bei heute üblichen Waschmaschinen Durchmesser in der Größenordnung von 3,5 mm. Dabei werden im Fertigungsprozeß der Trommel zunächst Löcher mit einem Durchmesser von ca. 2,5 mm in ein Blechcoil eingestanzt und anschließend durch einen Prägevorgang, das sogenannte Durchstellen, trichterförmig vertieft und auf 3,5 mm geweitet. Beim Formen und Verschweißen eines zugeschnittenen Coilteils zu einem zylindri schen Mantel wird die Vertiefung der Löcher nach außen gerichtet. Dies geschieht zu dem Zweck, daß am Lochrand evtl. vorhandene Grate nicht ins Trommelinnere ragen und so der Kontakt der Wäsche zu diesen Graten vermieden wird. Das Durchstellen und die damit ver bundene Strukturierung der Trommelinnenseite ergibt den Effekt, daß einerseits der Anteil der ebenen Oberfläche an der gesamten Mantelfläche verringert und andererseits das in die Trommel einfallende Licht diffus gespiegelt wird. Hierdurch wird zum einen der Eindruck von Solidität und Glanz, also hochwertigem Material vermittelt, außerdem fallen Kratzer oder Verun reinigungen weniger auf.In washing machines, it is common to include the drum jacket and possibly also the top surfaces Provide holes for an exchange of lye between laundry and tub is guaranteed. These holes have a diameter in today's washing machines the order of 3.5 mm. Here, in the manufacturing process of the drum first Holes with a diameter of approx. 2.5 mm are punched into a sheet metal coil and then through an embossing process, the so-called through, deepened in a funnel shape and to 3.5 mm widened. When shaping and welding a cut coil part into a cylindrical one The mantle of the hole is directed outwards. This happens to that Purpose so that any burrs on the edge of the hole do not protrude into the inside of the drum and so the Contact of the laundry to avoid these ridges. The putting through and the ver Bound structuring of the inside of the drum gives the effect that on the one hand the proportion of flat surface on the entire lateral surface reduced and on the other hand that in the Drum incident light is reflected diffusely. On the one hand, this gives the impression of Solidity and shine, i.e. high-quality material, and scratches or marks cleaning less.
Bei den vorgenannten Trommeln hat es sich als nachteilig erwiesen, daß die relativ großen Löcher bei Textilien zur Noppenbildung, zu Wäscheschäden und zum Durchtritt von Fäden und Fremdkörpern führen. Außerdem können Grate an den Lochrändern die Wäsche beschädigen. Es wurde deshalb bereits vorgeschlagen, den Lochdurchmesser zu verringern (DE 14 10 985) und/oder die Lochung auf Teilbereiche des Mantels zu begrenzen (DE 28 26 506).With the aforementioned drums, it has proven disadvantageous that the relatively large Holes in textiles for pimples, laundry damage and the passage of threads and Lead foreign bodies. Burrs on the edges of the holes can also damage the laundry. It has therefore already been proposed to reduce the hole diameter (DE 14 10 985) and / or to limit the perforation to partial areas of the jacket (DE 28 26 506).
Es ist außerdem bekannt, an der Innenseite des Trommelmantels Mitnehmer vorzusehen. Diese erstrecken sich in Längsrichtung und parallel zur Trommelachse und besitzen meist einen trapez-, parabel- oder dreieckförmigen Querschnitt. Im Mantelbereich unterhalb der Mitnehmer und in den Mitnehmern selbst können Löcher angeordnet sein, so daß diese als Schöpfeinrichtungen wirken (EP 0 236 282).It is also known to provide drivers on the inside of the drum shell. These extend in the longitudinal direction and parallel to the drum axis and usually have a trapezoidal, parabolic or triangular cross-section. In the coat area below the Drivers and holes in the drivers themselves can be arranged so that these as Scooping devices act (EP 0 236 282).
Der Erfindung stellt sich das Problem, eine Waschmaschine der eingangs dahingehend zu verbessern, daß Kontakte der Wäsche mit den Löchern weitgehend verhindert werden. The invention poses the problem of a washing machine to that effect improve that contacts of the laundry with the holes are largely prevented.
Erfindungsgemäß wird dieses Problem durch eine Waschmaschine mit den Merkmalen des Patentanspruchs 1 gelöst. Eine vorteilhafte Ausgestaltung der Endung ergibt sich aus dem nachfolgenden Unteranspruch.According to the invention, this problem is solved by a washing machine with the features of Claim 1 solved. An advantageous embodiment of the ending results from the subsequent subclaim.
Ein Ausführungsbeispiel der Erfindung ist in den Zeichnungen rein schematisch dargestellt und wird nachfolgend näher beschrieben. Es zeigtAn embodiment of the invention is shown purely schematically in the drawings and is described in more detail below. It shows
Fig. 1 den Querschnitt durch eine erfindungsgemäß aufgebaute Wasch maschinentrommel; Figure 1 shows the cross section through a washing machine drum constructed according to the invention.
Fig. 2 einen Teilschnitt durch die Waschmaschinentrommel gemäß Fig. 1. Fig. 2 is a partial sectional view of the drum washing machine of FIG. 1.
Die erfindungsgemäß ausgebildete Trommelwaschmaschine besitzt einen Laugenbehälter (nicht dargestellt), in dem in bekannter Weise eine Trommel (1) zur Aufnahme von Wäsche drehbar gelagert ist. Der Antrieb (nicht dargestellt) der Trommel (1) erfolgt durch einen Motor direkt oder über einen Keilriemen.The drum washing machine designed according to the invention has a tub (not shown), in which a drum ( 1 ) for receiving laundry is rotatably mounted in a known manner. The drive (not shown) of the drum (1) is effected by a motor directly or via a V-belt.
In den Mantel (1a) der Trommel (1) sind umlaufende Sicken (2) geprägt, die zum Trommel äußeren hinweisen. Der Bereich zwischen den Sicken (2) ist mit einem Gefälle zu den Sicken (2) hin versehen. Auf diese Weise wirken die Sicken (2) unter Fliehkraft wie eine Dachrinne.In the jacket ( 1 a) of the drum ( 1 ) surrounding beads ( 2 ) are embossed, which indicate the outside of the drum. The area between the beads ( 2 ) is provided with a slope to the beads ( 2 ). In this way, the beads ( 2 ) act as a gutter under centrifugal force.
Am Trommelmantel oder an den Deckflächen sind trapezförmige Mitnehmer (3) befestigt, die sich über den gesamten Mantel (1a) und parallel zur Trommelachse (1b) erstrecken. Im Bereich unter diesen Mitnehmern (3) sind Durchbrüche in Form von Bohrungen (4) angeordnet, die während des Waschvorgangs zum Schöpfen von Wasser und während des Schleuderns zum Entwässern verwendet werden.Trapezoidal drivers ( 3 ) are attached to the drum jacket or to the cover surfaces, which extend over the entire jacket ( 1 a) and parallel to the drum axis ( 1 b). In the area under these drivers ( 3 ) there are openings in the form of bores ( 4 ) which are used for scooping water during the washing process and for dewatering during the spinning.
