The wash drum (1) has ribs (3) which raise the washing articles above the water level before dropping them. Instead of them running from front to back they are divided (3a,3b) with one part (3b) lagging the other (3a) towards the rear of the drum to raise the clothes higher.

Description

Die Erfindung betrifft eine Waschmaschine oder eine Wäschetrocknungsmaschine gemäß dem Oberbegriff des Patentanspruchs 1.The invention relates to a washing machine or a laundry drying machine according to the preamble of the claim 1.

Die eingangs genannten Waschmaschinen oder Wäschetrocknungsmaschinen weisen eine drehbare die Wasche aufnehmende. Trommel auf, an deren Trommelmantel etwa rippenförmige Mitnehmer zum zumindest teilweisen Umführen der Wasche angeordnet sind. Die Mitnehmer sind herkömmlicherweise geradlinig über etwa die Breite des Trommelmantels angeordnet und führen die Wäsche zu einer Ablöseposition, an der sie sich vom Trommelmantel und von den Mitnehmern löst und in den unteren Trommelbereich zurückfällt. Es ist bekannt, dass die Form der Mitnehmer die mechanische Behandlung der Wäsche maßgeblich beeinflusst. Beispielsweise sind Mitnehmer bekannt, die konvexe, d. h. nach außen gewölbte Flänkeri aufweisen. Diese Form führt jedoch zu einer eher niedrigen Ablöseposition bzw. geringen Fallhöhe und zu einer verminderten Bewegung der Wäsche, so dass im Falle einer Waschmaschine längere Waschzeiten erforderlich sind, um ein zufriedenstellendes Reinigungsergebnis zu erhalten. Im Falle einer Wäschetrocknungsmaschine verlängert sich entsprechend die Trocknungsdauer. The washing machines or laundry drying machines mentioned at the beginning have a rotatable wash receiving. Drum, on the drum shell about rib-shaped drivers arranged to at least partially move the wash are. The drivers are traditionally straight arranged about the width of the drum shell and lead the laundry to a detachment position where it from the drum jacket and from the drivers and into the lower drum area falls back. It is known that the shape of the carriers the mechanical treatment of the laundry significantly influenced. For example, there are drivers known the convex, d. H. Flänkeri curved outwards exhibit. However, this form leads to a rather low one Detachment position or low fall height and to a reduced Movement of laundry so that in the case of a washing machine Longer wash times are required to get a satisfactory Get cleaning result. In the event of a laundry drying machine is extended accordingly the drying time.

Ausgehend von diesem Stand der Technik liegt der Erfindung die Aufgabe zugrunde, eine verbesserte mechanische Einwirkung auf die Wäsche zu erzielen.The invention is based on this prior art based on the task of improved mechanical action to achieve the laundry.

Diese Aufgabe wird nach den Merkmalen des Patentanspruchs 1 gelöst. Vorteilhafte Weiterbildungen sind in den Unteransprüchen angegebeneThis object is achieved according to the features of patent claim 1 solved. Advantageous further developments are in the subclaims specified

Ein Kern der Erfindung liegt darin, dass die Mitnehmer wenigstens zwei in Drehrichtung der Trommel voneinander beabstandete Abschnitte aufweisen, die derart wirksam sind, dass der in Drehrichtung betrachtet hintere Abschnitt zumindest einen Teil der an einer Ablöseposition befindlichen Wäsche am Trommelmantel hält. Durch die in Drehrichtung voneinander beabstandet angeordneten Abschnitte der Mitnehmer wird die Wäsqbe in eine höhere Ablöseposition gehoben als vergleichsweise bei geradlinig verlaufenden Mitnehmern, da der in Drehrichtung betrachtet hintere Abschnitt stets einen Teil der Wäsche am Trommelmantel hält, während der am vorderen Abschnitt liegende Teil der Wäsche sich vom Trommelmantel abzulösen beginnt. Darüber hinaus wird die Wäsche beim Zurückfallen in den unteren Trommelbereich stärker gedreht, so dass insgesamt eine stärkere Bewegung und somit eine intensivere mechanische Behandlung der Wäsche erzielt. wird. Sowohl der Wasch- als auch der Trockrungseffekt werden hierdurch wesentlich verbessert.A core of the invention is that the driver at least two spaced apart in the direction of rotation of the drum Have sections that are so effective that the rear section viewed at least in the direction of rotation a part of those in a detachment position Holds laundry on the drum jacket. By in the direction of rotation spaced apart portions of the driver the washer is raised to a higher release position compared to straight-line drivers, since the rear section viewed in the direction of rotation always holds part of the laundry on the drum jacket, while on Part of the laundry lying in the front section is separated from the drum jacket begins to replace. In addition, the laundry rotated more when falling back into the lower drum area, so overall a stronger movement and therefore achieved a more intensive mechanical treatment of the laundry. becomes. Both the washing and the drying effect will be thereby significantly improved.

Vorteilhafterweise sind die Mitnehmer mehrstückig, vorzugsweise zweistückig ausbildet, wobei sich die Abschnitte der Mitnehmer jeweils etwa senkrecht zur Drehrichtung über einen Bereich des Trommelmantels erstrecken, so dass die Mitnehmer im wesentlichen über die Breite des Trommelmantels wirksam sind. Die Abschnitte sind zweckmäßigerweise so gegeneinander versetzt angeordnet, dass über die Breite des Trommelmantels keine größere Lücke entsteht, durch welche Wäschestücke hindurchgleiten können. Ferner wird durch diese konstruktive Maßnahme bei einer Waschmaschine die Waschflüssigkeit an den Abschnitten stärker verwirbelt, was zu einer besseren Durchflutung und schnelleren Reinigung der Wäsche beiträgt. Bei einer Wäschetrocknungsmaschine führt diese Maßnahme zu einer Auflockerung und somit zu einer besseren Durchlüftung der Wäsche, so dass die Trocknung der Wäsche beschleunigt wird.The carriers are advantageously in several pieces, preferably trains in two parts, the sections of the Driver each approximately perpendicular to the direction of rotation via a Extend the area of the drum shell so that the driver essentially across the width of the drum shell are effective. The sections are expediently so against one another staggered that across the width of the Drum shell no larger gap arises, through which Linen items can slide through. Furthermore, through this constructive measure in a washing machine the washing liquid swirled more at the sections, leading to better circulation and faster cleaning of the Laundry contributes. Leads in a laundry drying machine this measure to loosen up and thus to a better ventilation of the laundry, so that the drying of the Laundry is accelerated.

Besonders bevorzugt sind die Mitnehmer- gebogen, vorzugsweise etwa S-förmig gebogen ausgebildet, wobei sich die Abschnitte jeweils etwa senkrecht zur Drehrichtung über einen Bereich des Trommelmantels erstrecken und über einen etwa schräg zur Drehrichtung verlaufenden Zwischenabschnitt der Mitnehmer miteinander verbunden sind, so dass die Mitnehmer im wesentlichen über die Breite des Trommelmantels wirksam sind. Diese Ausführungsform führt beim Waschvorgang ebenfalls zu einer starken Verwirbelung der Waschflüssigkeit an den Abschnitten sowie zu einer verbesserten Durchlüftung der Wäsche beim Trocknungsvorgäng. Darüber hinaus erfordern die S-förmig gebogenen Mitnehmer einen sehr geringen Befestigungsaufwand und können somit auch an einem dünnen Trommelmantel befestigt werden.The driver bends are particularly preferred, preferably formed approximately S-shaped, the sections each approximately perpendicular to the direction of rotation via a Extend the area of the drum shell and about an intermediate section of the Carriers are connected together so that the carriers effective essentially across the width of the drum shell are. This embodiment also leads to the washing process to a strong swirling of the washing liquid the sections as well as for improved ventilation the laundry during the drying process. Also require the S-shaped curved driver requires very little effort and can therefore also be used on a thin drum jacket be attached.

Vorteilhafterweise entspricht der Abstand der Abschnitte in Drehrichtung mindestens etwa der Breite, vorzugsweise etwa der zweifachen Breite der Basis der Abschnitte, so dass ein signifikantes Anheben der Wäsche in eine höhere Ablöseposition und eine verstärkte Drehbewegung der Wäsche erzielt wird.The distance between the sections in FIG Direction of rotation at least about the width, preferably about twice the width of the base of the sections, making a significant lifting of the laundry in a higher detachment position and achieved an increased rotational movement of the laundry becomes.

Die Erfindung wird nachstehend, auch hinsichtlich weiterer Merkmale und Vorteile, anhand von Ausführungsbeispielen und unter Bezugnahme auf die beiliegenden Zeichnungen näher erläutert.The invention is set out below, also with respect to others Features and advantages, based on exemplary embodiments and explained in more detail with reference to the accompanying drawings.

FIG 3
a plan view of a driver according to another embodiment.

In FIG 1 ist eine die Wäsche aufnehmende Trommel 1 einer Waschmaschine in Schnittansicht gezeigt. Die Trommel 1 weist längs ihres zylinderförmigen Trommelmantels 2 drei etwa rippenförmige Mitnehmer 3 auf, die in den Trommelinnenraum vorstehen und die Wäsche teilweise umführen bzw. zu einer erhöhten Ablöseposition P führen. Die Trommel 1 ist wechselweise im Uhrzeigersinn und entgegengesetzt zum Uhrzeigersinn drehbar, wobei der Übersichtlichkeit halber lediglich die Drehrichtung D im Uhrzeigersinn dargestellt ist. Wie in den FIG 1 und 2 erkennbar ist, sind die Mitnehmer 3 gemäß einer ersten Ausführungsform zweistückig ausgebildet und umfassen jeweils einen in Drehrichtung D betrachtet vorderen, der Trommelrückwand 7 zugeordneten Abschnitt 3a und einen hinteren, der Trommelstirnwand 8 zugeordneten Abschnitt 3b. Die Abschnitte 3a und 3b erstrecken sich senkrecht zur Drehrichtung D über etwa die Hälfte der Breite B des Trommelmantels 2, so dass die Mitnehmer 3 im wesentlichen über die Breite B des Trommelmantels 2 wirksame sind. Die Mitnehmer 3 bzw. die Abschnitte 3a und 3b weisen seitliche Flanken 4 auf, die schräg an einen flächig ausgebildeten Scheitelbereich 5 angrenzen. Der Scheitelbereich 5 ist mit Öffnungen 6 versehen, um die Wäsche von oben her mit' Waschflüssigkeit zu beregnen.
Die Abschnitte 3a und 3b weisen in Drehrichtung D einen Abstand A auf, der etwa der zweifachen Breite b der Basis der Abschnitte 3a und 3b entspricht. Durch die in Drehrichtung D wirksamen und gegeneinander versetzt angeordneten Abschnitte 3a und 3b hält der hintere Abschnitt 3b stets einen Teil der an der Ablöseposition P befindlichen Wasche am Trommelmantel 2, während der am vorderen Abschnitt 3a liegende Teil der Wäsche sich zu lösen beginnt. Die Wäsche wird dadurch in eine höhere Ablöseposition gehoben und führt beim Ablösen vom Trommelmantel 2 bzw beim Zurückfallen in die Wäschflüssigkeit eine stärkere Drehbewegung aus, die in FIG 1 durch den Pfeil R verdeutlicht ist. Zusätzlich bewirken die voneinander beabstandeten Abschnitte 3a rund 3b eine stärkere Verwirbelung der Waschflüssigkeit.
1 shows a laundry drum 1 of a washing machine in a sectional view. The drum 1 has along its cylindrical drum shell 2 three approximately rib-shaped drivers 3 which protrude into the interior of the drum and partially guide the laundry or lead to an elevated detachment position P. The drum 1 can be rotated alternately clockwise and counterclockwise, for the sake of clarity only the direction of rotation D is shown clockwise. As can be seen in FIGS. 1 and 2, the catches 3 are formed in two pieces in accordance with a first embodiment and each comprise a section 3a, which is assigned to the drum rear wall 7 and viewed in the direction of rotation D, and a rear section 3b which is assigned to the drum end wall 8. The sections 3a and 3b extend perpendicular to the direction of rotation D over approximately half the width B of the drum shell 2, so that the drivers 3 are essentially effective over the width B of the drum shell 2. The drivers 3 or the sections 3a and 3b have lateral flanks 4 which are obliquely adjacent to a flat apex area 5. The apex area 5 is provided with openings 6 in order to irrigate the laundry with washing liquid from above.
The sections 3a and 3b have a distance A in the direction of rotation D which corresponds approximately to twice the width b of the base of the sections 3a and 3b. Due to the sections 3a and 3b which are effective in the direction of rotation D and are arranged offset with respect to one another, the rear section 3b always holds part of the laundry located at the detachment position P on the drum jacket 2, while the part of the laundry lying on the front section 3a begins to detach. The laundry is thereby lifted into a higher detachment position and performs a stronger rotary movement when detached from the drum jacket 2 or when it falls back into the washing liquid, which is illustrated by the arrow R in FIG. In addition, the spaced sections 3a and 3b cause a greater swirling of the washing liquid.

In FIG 3 ist eine zweite Ausführungsform der Mitnehmer in Draufsicht gezeigt. Die Mitnehmer. 3 sind etwa S-förmig gebogen und weisen jeweils einen in Drehrichtung D betrachtet vorderen, der Trommelrückwand 7 zugeordneten Abschnitt 3a und einen hinteren, oder Trommelstirnwand 8 zugeordneten Abschnitt 3b auf. Die Abschnitte 3a und 3b erstrecken sich senkrecht zur Drehrichtung D über einen Bereich, vorzugs weise über mindestens etwa ein Drittel der Breite B des Trommelmantels 2, und sind über einen schräg zur Drehrichtung D verlaufenden Zwischenabschnitt 3c verbunden. Die Mitnehmer 3 bzw. die Abschnitte 3a, 3b und 3c weisen seitliche Flanken 4. auf, die an einen flächig ausgebildeten und mit Öffnungen 6 versehenen Scheitelbereich 5 angrenzen. Der Abstand A zwischen dem vorderen Abschnitt 3a und dem hinteren Abschnitt 3b entspricht etwa der zweifachen Breiteb der Basis der Abschnitte 3a, 3b bzw. 3c.3 shows a second embodiment of the driver in Top view shown. The carriers. 3 are bent approximately S-shaped and each have one viewed in the direction of rotation D. front section 3a associated with the drum rear wall 7 and a rear or drum end wall 8 associated section 3b on. Sections 3a and 3b extend perpendicular to the direction of rotation D over an area, preferably over at least about a third of the width B of the Drum casing 2, and are at an angle to the direction of rotation D extending intermediate section 3c connected. The Driver 3 or sections 3a, 3b and 3c have lateral Flanks 4th on a flat trained and adjoin the apex region 5 provided with openings 6. The Distance A between the front section 3a and the rear Section 3b corresponds approximately to twice the width the base of sections 3a, 3b and 3c, respectively.

Die S-förmig gebogenen Mitnehmer 3 führen ebenso wie die zweistückig ausgebildeten Mitnehmer 3 gemäß der ersten Ausführungsform zu einem optimalen Reinigungsergebnis. Die Wäsche wird in eine höhere Ablöseposition gebracht und beim Zurückfallen in die Waschflüssigkeit stärker gedreht. Darüber hinaus wird die Waschflüssigkeit stärker verwirbelt, so dass insgesamt eine intensivere mechanische Behandlung der Wäsche erreicht wird. Infolgedessen kann sowohl die Waschzeit als auch der Wasser, Energie und Waschmittelverbrauch reduziert werden, so dass sich die mit denn Mitnehmern 3 bestückte Waschmaschine durch eine erheblich verbesserte Wirtschaftlichkeit auszeichnet. Die S-förmigen Mitnehmer 3 gemäß FIG 3 erfordern ferner einen geringen Befestigungsaufwand und können auf einfache Weise an einem dünnen Trommelmantel 2 befestigt werden. Sowohl die S-förmigen Mitnehmer 3 gemäß FIG 3 als auch die zweistückig ausgebildeten Mitnehmer 3 gemäß den FIG 1 und 2 sind derart am Trommelmantel 2 positioniert, dass das Reinigungsergebnis unabhängig davon ist, ob die Trommel 1 im Uhrzeigersinn (Drehrichtung D) oder entgegengesetzt zum Uhrzeigersinn gedreht wird.The S-shaped driver 3 lead just like that two-piece driver 3 according to the first embodiment for an optimal cleaning result. The laundry is brought into a higher release position and at Fall back into the washing liquid rotated more. About that in addition, the washing liquid is more swirled, so overall a more intensive mechanical treatment the laundry is reached. As a result, both the Washing time as well as water, energy and detergent consumption be reduced, so that with the carriers 3 equipped washing machine through a significantly improved Economy. The S-shaped Carriers 3 according to FIG 3 also require little effort and can easily on one thin drum shell 2 are attached. Both the S-shaped Driver 3 according to FIG 3 and the two pieces trained carrier 3 according to FIGS 1 and 2 are of this type positioned on the drum jacket 2 that the cleaning result regardless of whether drum 1 is clockwise (Direction of rotation D) or turned counterclockwise becomes.

Die oben beschriebenen Mitnehmer 3 können ebenfalls in einer Wäschetrocknungsmaschine verwendet werden. Die voneinander beabstandeten Abschnitte 3a und 3b bewirken eine stärkere Drehbewegung und zugleich eine Auflockerung der Wäsche, so dass eine bessere Durchlüftung und somit ein optimaler Trocknungseffekt gewährleistet ist. Infolgedessen kann die Trocknungsdaüer erheblich verkürzt werden. The driver 3 described above can also in one Laundry drying machine can be used. The one from the other spaced sections 3a and 3b cause one stronger rotation and at the same time a loosening of the Laundry, so that better ventilation and thus an optimal Drying effect is guaranteed. Consequently the drying time can be shortened considerably.
