Definitions

  • the invention relates to a washing machine according to the preamble of claim 1 and a method for washing of laundry in a washing machine according to the preamble of Claim 9.
  • Laundry is common in households but also in laundromats washed in washing machines that have a rotating, have the laundry receiving drum.
  • the washing process is in addition to the addition of detergents in a washing liquid decisive also through mechanical processing of the laundry item.
  • the Drum on its drum jacket in particular rib-shaped Carriers on the rotation of the laundry drum raise the item of laundry until it moves away from the one taking it Rib loosens and falls down to from the subsequent one Driving rib to be raised again.
  • the item of laundry rotates by one axis of rotation passing through it.
  • the duration of a washing program depends essentially not only on the amount and concentration of the added cleaning agent but also from the Intensity of the washing mechanism.
  • the essential essence of the invention is that on the laundry has an increased mechanical impact becomes. This is achieved by washing the laundry in the drum, which extends in a depth direction, viewed over the drum depth in a depth range higher is raised than in another depth range. On this way, the laundry lot does not just become one Rolling movement causes, rather it finds an additional Twisting the laundry item instead, which is an additional mechanical influence on the laundry.
  • the coherent item of laundry raised more than in the rear area of the Drum when the top edge of the drum rotates of the driver in the rear area of the upper edge of the Driver runs in the front area.
  • the carrier is made up of several parts and that individual driver parts arranged in steps on the drum shell are. It turned out that then partial overlap of the individual steps is cheap is.
  • the driver is preferably formed in one piece and has an upper edge or top surface that has an S shape or Z shape. Such training of the In any case, the driver has advantages when it comes to assembly because of the one-piece. Another advantage is that each carrier has one over the other large angular range extending support surface results in the drum jacket, making the drum particularly good is stiffened. This can also reduce costs by reducing the thickness of the sheet metal used can be achieved.
  • a special embodiment of the invention provides that the bottom surface of the driver is at least approximately rectangular is or an approximately rectangular basic shape with rounded has short sides, so for safe Sufficient support area on the drum jacket is present and that the driver is up to his Tapered top surface or top edge.
  • the three-dimensional Training is such a driver with a mountain range comparable, that of a rectangular valley area and one S-shaped or Z-shaped mountain ridge.
  • a particularly suitable embodiment of the invention sees an S or Z-shaped formation not only the top surface or top edge but also the bottom surface of the driver in front.
  • Such a configuration results as a result an additional stiffening of an enlarged contact surface of the drum shell and the driver is also safer to fix on the drum jacket.
  • this special shape of the driver a significantly higher Offset of the individual top surface or top edge areas be adjusted, which is a further increase in mechanical Effect.
  • the driver a first edge and has a second flank opposite the first flank, the first flank at least in a partial area the driver length of a rising straight line or one rising curved curve follows and the second Flank at least in a partial area of the driver length is perpendicular to the drum jacket.
  • the vertical flank lying behind in the direction of rotation this leads steep Decline of the driver back to swirl the Washing liquid, with such swirled water also acts mechanically on the laundry and above in addition, when washing the laundry, the flow is improved.
  • the different training of the first and the second Flank also has an impact on the deadweight effect of the respective driver area.
  • an obliquely trained Flanking the laundry item is significantly lower given. For this reason, it is particularly cheap and the increase in mechanical impact is particularly beneficial, if in the area of the leading upper edge or Top surface of the laundry items meets an oblique edge, while in the area of the trailing upper edge or top surface there is a steep flank. The laundry item is thus loosened from the leading top edge or top surface even earlier and the twist of the laundry item is still more pronounced.
  • drum Carrier there are several in one drum Carrier includes, so can in the course of a revolution a possibly changing direction of twist the Washing mechanics can be further improved. This will be achieved that at least two connected in series Drivers the sign of the offset of the top surface or top edge areas changes.
  • the laundry receiving drum 1 is one Washing machine shown in sectional view.
  • the drum 1 has three on its approximately cylindrical drum shell evenly spaced, approximately rib-shaped Driver 3, which protrude into the interior of the drum and partially move the laundry or to a higher position to lift.
  • the drum 1 is about an approximately horizontal axis of rotation A rotatable, the drum 1 alternately clockwise and turned counterclockwise.
  • the first flank 4 comprises a front, the area 4a associated with the drum end wall 9, the is concave, and a rear, the drum rear wall 10 associated area 4b, which is flat-shaped and arranged substantially vertically on the drum shell 2 is.
  • a transition region 8 is formed, in which the concave trained area 4a continuously in the just shaped Area 4b merges.
  • the second edge 5 is such formed that the front, concave area 4a of the first flank 4 a front, just shaped and positioned approximately vertically on the drum shell 2 Area 5a is opposite.
  • the transition area 8 is the just shaped Area 5a continuously in the concave Area 5b above.
  • the first edge 4 and the second edge 5 are adjacent to one flat formed apex area 6, which is essentially extends over the length L of the driver 3.
  • the Vertex area 6 is corresponding to the predominantly asymmetrical Cross section of the driver 3 at the front areas 4a and 5a and at the rear areas 4b and 5b off center over the base of the drum jacket 2
  • Driver 3 positioned and approximately S-shaped in the transition area 8 bent.
  • the apex region 6 has openings 7 provided to the washing liquid taken up by the carrier 3 to be placed on the laundry at the highest possible position.
  • the led with the driver 3 according to the invention Linen items will undergo increased mechanical treatment exposed. This happens because of the whole Drum depth extending through the laundry Driver 3 is raised to different degrees.
  • the of of the front carrier half transported laundry item part meets the concave flank area there 4a.
  • the driver flank area 4a points through its concave form of training poor driver characteristics because such a training as a slide for the laundry item works.
  • the front laundry item will therefore not raised as much as the rear laundry item, the one on the perpendicular to the drum surface Edge area 4b meets. That in the front and in rear area of the laundry drum 1 to different degrees pronounced driving behavior of the driver 3 causes Falling of the laundry item at different times, so that the laundry item is twisted overall and is therefore machined more than one trained uniformly over the entire length of the driver Flank.
  • FIG. 4 Another and preferred form of training according to FIG. 4 reinforces this twisting effect even further.
  • the driver 3 'according to FIG. 4 not only has an apex region 6 on, the front and rear section to each other are arranged offset and the central region is approximately S-shaped is designed, rather there is one geometric configuration also on the bottom of the driver 3 ' again, on which the driver 3 'with the inner drum surface 2 is coupled.
  • the S shape of the driver 3 'according to Figure 4 reversed, d. H. the leading driver half is at rotation the drum clockwise (starting from Figure 1) now in the front half of the drum. At such a leading The half of the driver that is taken away falls Linen items start earlier.
  • Both embodiments according to Figures 1 to 3 and according to Figure 4 has in common that a pronounced treatment of the Wash with swirled washing liquid.
  • This particular one Turbulence of the washing liquid results on steeply sloping flank area 4b, 4b 'or 5a 5a', each according to which direction of rotation the drum 1 has.
  • washing machines in reverse operation d. H. with changing drum direction of rotation, operated in a steeply falling drum flank area in each direction of rotation 4b, 4b 'or 5a, 5a' is present.
  • the swirl the washing liquid comes about because the steeply falling flank area 4b, 4b 'or 5a.
