Definitions

  • the invention relates to a drum-type washing machine with a coat-loading design, with a tub, to the front of which ballast masses are attached and in the interior of which a washing and centrifuging drum is arranged.
  • Drum washing machines of this type are already known with a self-supporting tub made of plastic, the side walls of the tub are curved outwards for reasons of stability and the drum side walls also have such an outward-facing curvature.
  • ballast mass for the imbalance compensation can only be attached to the outer shell of the tub if the width of the washing machine is not to be increased, or that only a relatively narrow washing and spinning drum can be used if the ballast mass to be attached to the front of the tub.
  • a very narrow washing and spinning drum leads to limitations in the washing effects and the volume of the laundry to be washed.
  • a generic drum washing machine is known from FR-A-2 163 361.
  • this drum washing machine with the features mentioned above also has the disadvantages already described.
  • the present invention is therefore based on the object to avoid the disadvantages mentioned above in a drum washing machine of the type mentioned at the outset, in particular to create a drum washing machine with the largest possible drum capacity with a very good washing and dewatering effect.
  • this object is achieved in that the washing and centrifuging drum tapers from its outer region to its center of rotation, and that the tub end walls are made narrower in the direction of the center of rotation than in its outer region.
  • the drum shape according to the invention now provides more space compared to solutions according to the prior art with the same installation space.
  • the drum washing machine according to the invention is significantly smaller in width with the same laundry performance compared to known designs.
  • a simple constructive solution for the design of the washing drum can consist in the fact that the drum side walls have flat, frustoconical depressions.
  • the force line distance or course between the bearing elements of the washing drum is smaller than the maximum drum width.
  • a further advantageous constructive embodiment of the invention can consist in that a region of the drum side walls adjoins the truncated cone-shaped recesses in the direction of the peripheral wall, which region is straight or perpendicular to the axis of rotation.
  • this configuration enables a maximum width for the laundry ring formed during the spinning process, which reduces the thickness of the laundry ring and consequently that for the dewatering effect relevant average centrifugal acceleration is highest. Furthermore, the flow paths of the fleet to be ejected are minimized, which can also have a favorable effect on the drainage effect.
  • drum washing machine is basically of a known type, only the parts essential to the invention are described in more detail below.
  • the basic structure of the drum washing machine is shown in cross section, the volume of the dripping wet laundry, which this requires at maximum filling mass, is approximately 60-70% of the volume of a washing drum 1, the laundry being washed during rapid rotations of the washing drum 1 is available as a laundry ring.
  • the laundry is circulated with the aid of turning ribs 9 in such a way that a required free space for inside the washing drum 1 there is a free falling movement of the laundry.
  • This falling movement which is particularly important for the washing and rinsing effect, is the better the larger the diameter of the free space in the washing drum 1.
  • the two drum side walls 2 have flat, frustoconical depressions 3 in such a way that the washing drum 1 is recognizably narrower in its center of rotation than in its outer region. This taper runs evenly.
  • the width of the center of the drum 8 (see arrow) can correspond approximately to 5/6 to 4/5 of the maximum drum width 7 (see arrow).
  • the angle of the frustoconical depressions can be 150-160 ° in each case.
  • the diameter of the washing and centrifuging drum 1 can be between 440-480 mm and its width between 280-320 mm.
  • the suds container end walls 4 are drawn in or dipped in such a way that the force line distance between the bearing elements 5 of the washing drum 1 is smaller than the maximum drum width 7.
  • the outer diameter of the frusto-conical depressions 3 is approximately 3/4 to 4/5 of the drum diameter.
  • An outer region 12 is also connected to these truncated cone-shaped depressions 3, in which the two drum side walls 2 run in a straight line or perpendicular to the axis of rotation.
  • the arrangement of the bearing elements 5, generally ball or roller bearings, within the maximum drum width 7 also ensures optimal conditions, both in the drum side walls 2, as well as in the tub end walls 4 and on the other hand also fixed, from stiffening ribs 6, the the tub end walls 4 are arranged on the inside, surrounding bearing seats.
  • ballast masses 10 are arranged in a space-saving design, the ballast masses 10 also being able to be formed inward in the inner region due to the retracted walls.
  • This flat arrangement of the ballast masses 10 on the front side achieves good vibration and load conditions with regard to compensation of unbalance in all vibration levels.
