Definitions

  • the invention relates to a washing machine according to the preamble of patent claim 1 or claim 2.
  • Laundry is usually washed in households but also in launderettes in washing machines, which have a rotatable, the laundry receiving drum.
  • the washing process is also decisively influenced by mechanical processing of the laundry item.
  • the drum on its drum shell in particular rib-shaped driver, which raise the laundry items during the rotational movement of the laundry drum until it releases from the entraining him rib and falls down to be raised again by the subsequent driving rib.
  • the laundry item completes a rotary movement about a rotational axis passing through it.
  • the duration of a washing program depends essentially not only on the amount and concentration of the added detergent but also on the intensity of the washing mechanism.
  • washing machines are known, for example, from FR-A-1 136 981, JP-A-10235075, WO-A-00/75411 and DE-A-4021533.
  • the essential essence of the invention is that an increased mechanical action is exerted on the laundry. This is achieved by raising the laundry in the laundry drum, which extends in a depth direction, above the drum depth in a depth range higher than in another depth range. In this way, the laundry item is not only caused to a rolling motion, but it also takes place in addition to twisting the Wäschepostens, which causes an additional mechanical impact on the laundry.
  • a washing machine which performs this increased mechanics is characterized in that at least one driver for at least partially circulating the laundry is arranged in a rotating cylindrical drum on the drum casing, said driver being up to and from its bottom surface via which it is coupled to the drum casing its spaced from the drum shell top surface or upper edge, wherein the top surface or top edge over its length considered at least two different angular ranges associated with each projection on the drum rear wall.
  • the continuous laundry item is raised more than in the rear region of the drum, when the upper edge of the drum during the rotary movement of the driver trailing in the rear area of the upper edge of the driver in the front area.
  • Such an offset of the upper edge of the driver rib seen over the depth of the laundry drum can be achieved in that the driver is constructed in several parts and the individual driver parts are arranged like a staircase on the drum shell. It has been found that then a partial overlap of the individual steps is favorable.
  • the driver is integrally formed and has an upper edge or top surface, which has an S-shape or Z-shape.
  • Such a design of the driver has definitely advantages in the assembly just because of the one-piece.
  • Another advantage is that with each driver results in a over a particularly large angular range extending support surface on the drum shell, so that the drum is particularly well stiffened. Thus, a cost reduction by reducing the thickness of the sheet material used can be achieved.
  • a particular embodiment of the invention provides that the bottom surface of the driver is at least approximately rectangular or has an approximately rectangular basic shape with rounded short sides, so that there is a sufficient support surface for secure attachment to the drum shell and that the driver up to its top surface or Upper edge tapered.
  • the three-dimensional design of such a driver is comparable to a mountain range having a rectangular valley area and an S- or Z-shaped ridge.
  • a particularly suitable embodiment of the invention provides an S- or Z-shaped design not only of the top surface or upper edge but also the bottom surface of the driver before. Such a configuration causes an additional stiffening of the drum shell due to an enlarged support surface and the driver is also safer to fix the drum shell. In addition, a significantly higher offset of the individual top surface or top edge areas can be adjusted by this particular shape of the driver, resulting in a further increase in the mechanical impact.
  • a further shortening of the washing time can be achieved in that the driver has a first flank and a second flank opposite the first flank, wherein the first flank follows at least in a partial region of the driver length a rising straight line or a rising curved curve and the second flank at least lies in a portion of the driver length perpendicular to the drum shell. If the vertical flank lies in the direction of rotation in the back, this steep drop in the rear of the driver results in swirling of the washing liquid, whereby water swirled in such a way also acts mechanically on the laundry and, moreover, improves its flow when the laundry is rinsed.
  • the washing drum usually changes its direction of rotation several times during the washing process, it is particularly favorable if, in the case of an S-shaped or Z-shaped upper edge or top surface of the carrier, the first and second flanks are in the course of this S or Z shape Swap alignments. In this way, the driver in each direction partially on a steep back for this Verwirbelungsvorgang.
  • the different design of the first and the second edge also has an influence on the entrainment effect of the respective driver area.
  • the entrainment of the laundry costs significantly lower.
  • it is particularly favorable and particularly conducive to increasing the mechanical action when the laundry item encounters an oblique edge in the region of the leading upper edge or cover surface, while a steep flank is present in the region of the trailing upper edge or cover surface.
  • the batch of laundry dissolves from the leading upper edge or top surface even earlier and the twisting of the laundry item is even more pronounced.
  • the washing mechanism can be further improved in the course of one revolution by means of an optionally multiple twisting direction. This is achieved by changing the sign of the offset of the top surface or top edge regions in the case of at least two drivers connected in series.
  • a laundry receiving drum 1 of a washing machine is shown in sectional view.
  • the drum 1 has at its approximately cylindrical drum shell 2 on three equally spaced apart, such as rib-shaped carrier 3, which protrude into the drum interior and partially wrap the laundry or lift in a higher position.
  • the drum 1 is rotatable about an approximately horizontal axis of rotation A, wherein the drum 1 is alternately rotated in a clockwise and counterclockwise direction.
  • the first edge 4 comprises a front, the drum end wall 9 associated region 4a, which is concave, and a rear, the drum rear wall 10 associated region 4b, which is just shaped and substantially perpendicular to the Drum shell 2 is arranged.
  • a transition region 8 is formed, in which the concave portion 4a continuously merges into the newly shaped portion 4b.
  • the second flank 5 is formed such that the front, concave portion 4a of the first edge 4 a front, just shaped and approximately perpendicular to the drum shell 2 positioned region 5a is opposite.
  • the rear, flat-shaped region 4b of the first flank 4 faces a rear, concavely formed region 5b of the second flank 5.
  • the newly shaped region 5a continuously merges into the concave region 5b.
  • the first flank 4 and the second flank 5 adjoin a surface-formed apex region 6, which extends substantially over the length L of the driver 3.
  • the apex region 6 is positioned eccentrically above the base of the driver 3 lying on the drum shell 2 in accordance with the predominantly asymmetrical cross section of the driver 3 at the front regions 4a and 5a and at the rear regions 4b and 5b, and bent approximately S-shaped in the transition region 8.
  • the apex region 6 is provided with openings 7 to deliver the washing liquid received by the driver 3 at the highest possible position on the laundry.
  • the batch of laundry handled with the driver 3 according to the invention is subjected to an increased mechanical treatment. This happens because the over the entire drum depth extending laundry items is raised by the driver 3 different levels.
  • the laundry item transported by the front driver half strikes the concave flank area 4a present there.
  • the Mitauerflanken Society 4a has by its concave design bad handling properties on, since such education acts as a kind of slide for the laundry items.
  • the front laundry item part is thus not raised as much as the rear laundry item part, which meets the perpendicular to the drum surface edge portion 4b.
  • FIG. 4 Another and preferred embodiment of Figure 4 further enhances this Verwindungs free.
  • the driver 3 'in accordance with FIG. 4 not only has an apex region 6 whose front and rear portions are offset from one another and whose middle region is approximately S-shaped, but such a geometric configuration is also found at the bottom of the driver 3'. at which the driver 3 'is coupled to the drum inner surface 2.
  • the S-shape of the driver 3 'in Figure 4 mirror-inverted, ie the leading Mit Economics is in rotation of the drum in a clockwise direction (starting from Figure 1) now in the front drum half. At such a leading driver half of the thereby entrained laundry items falls earlier in time.
  • Both embodiments according to Figures 1 to 3 and according to Figure 4 has in common that a pronounced treatment of the laundry with fluidized washing takes place.
  • This particular turbulence of the washing liquid results at the steeply sloping edge region 4b, 4b 'or 5a 5a', depending on which direction of rotation the drum 1 has.
  • washing machines are in Reversier Sciences, d. H. operated with changing drum rotation direction, wherein in each direction of rotation in each case a steeply sloping drum edge region 4b, 4b 'or 5a, 5a' is present.
  • the turbulence of the washing liquid is due to the fact that the steeply sloping edge region 4b, 4b 'and 5a.
