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 plastic tub, the side walls of the tub being 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 jacket 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 is on the front of the tub should be attached.
  • a very narrow washing and spinning drum leads to limitations in the washing effects and the volume of the laundry to be washed.
  • the present invention is therefore based on the object of avoiding the aforementioned disadvantages in a drum washing machine of the type mentioned at the outset, in particular to provide a drum washing machine with the largest possible drum capacity with a very good washing and dewatering effect.
  • the object is achieved in that the washing and centrifuging drum tapers from its outer region to its center of rotation.
  • the drum shape according to the invention now provides more space compared to solutions according to the prior art with the same installation space.
  • 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.
  • a particularly advantageous development according to the invention can consist in that the tub end walls are also made narrower in the direction of the center of rotation than in their outer area.
  • the drum washing machine according to the invention is significantly smaller in width with the same laundry performance compared to known designs.
  • 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 the average centrifugal acceleration which is decisive for the dewatering effect 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 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 necessary free space is created in the interior of the washing drum 1 for the laundry to fall freely.
  • This falling movement which is particularly important for the washing and rinsing effect, is better the larger the diameter of the free space in the 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 each.
  • the diameter of the washing and centrifuging drum 1 can be between 440-480 mm and its width between 280-320 mm.
  • the inwardly directed recesses in the central area are followed by straight or perpendicular areas to the axis of rotation. These rectilinear areas also serve as flange mounting for the bearing elements 5.
  • 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 specified dimensional coordination between the width of the drum center 8 and the maximum drum width 7 and between the drum diameter and the outer diameter of the truncated cone-shaped recess 3 achieves a balanced relationship between the required stiffness of the drum and a required washing ring volume for the most common and most important filling mass spectrum.
  • the arrangement of the bearing elements 5, generally ball or roller bearings, within the maximum drum width 7 also ensures optimal load conditions, both in the drum side walls 2, and in the tub end walls 4 and, on the other hand, also fixed, of stiffening ribs 6, which 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.
