Definitions

  • the invention relates to a washing method for a program-controlled drum washing machine with control means for the speed adjustment of the drive motor and a laundry drum rotatably mounted in a tub, which has at least one drum rib in its interior, the drum rib being formed with water outlet openings and water inlet openings, such that the drum rib a scooping effect which is effective in both directions of rotation of the drum arises and that cycles of higher and lower drum speeds can be set during the washing cycle.
  • the specified washing process is intended on the one hand to achieve thorough mixing of the laundry in the higher speed range (mechanics) and on the other hand to intensively moisten or flood the item of laundry and at the same time to save energy and water.
  • DE-OS 37 12 118 describes a drum washing machine with drum ribs designed in a manner known per se as scoops. These scoops or drum ribs are intended to support the moistening of the laundry by taking wash liquor at a lower speed at the beginning of the wash cycle and letting it trickle onto the laundry from above.
  • the invention is therefore based on the object of designing a washing method for a program-controlled drum washing machine so that there is a constant change from higher and lower washing speed during the entire washing cycle, so as to improve the washing effect and the utilization of the detergents and at the same time saves energy and water to act.
  • This object is achieved by the features of claim 1.
  • the advantages which can be achieved with the invention are, in particular, that washing is carried out at the start of the wash cycle at a higher speed and a lower speed in the course of a switch-on period of the drive motor. This ensures that the detergent dissolves well and that the laundry is optimally moistened right at the start of the wash cycle.
  • the constant alternation of high and low speed results in a thorough mixing of the laundry with an optimal washing effect on the one hand and a good washing flow on the other.
  • the temporary attitude The lower speed in the course of the entire wash cycle favors the scooping effect of the drum rib and the intensive washing load.
  • the drawing shows a speed diagram with a speed gradation in the switch-on periods of the drive motor.
  • a gradual change in the drum speed takes place within the switch-on period of the drive motor.
  • the drum is first accelerated to the increased speed n1 and after a period of z. B. 2 to 6 seconds driven at the lower speed n2.
  • the speed n1 is preferably in a range from 50 to 60 min ⁇ 1 and the speed n2 in a range from 35 to 45 min ⁇ 1.
  • the drum is driven in reverse mode during the wash cycle.
  • the drum diameter is in a range from 430 to 500 mm. In the example shown, the drum is driven for about 5 to 6 seconds (t1) at a speed of 55 min ⁇ 1 and then for about 5 to 6 seconds (t2) at a speed of 40 min ⁇ 1.
  • the drive motor first set the speed of 55 min ⁇ 1 for a time of 3 seconds and then the lower speed of 40 min ⁇ 1 for 3 seconds. After a pause of 9 seconds, the next switch-on period follows with a changed direction of rotation.
  • the washing process described above is used in washing programs with and without prewash.
  • the drum is driven for a short period of time at the stepped speed n1 / n2 according to claim 1 in order to detach the dirt from the fiber.
  • the drum is driven only at a stepped speed n1 / n2 according to claim 1.
