Definitions

  • the invention relates to a method for correcting the unbalance size limit value for a program-controlled washing machine with a motor-driven washing and spinning drum, in which an unbalance size limit value for the centrifuged material is entered into the program control unit.
  • a method for controlling the spin program of a washing machine is known from DE-OS 26 20 464, in which an unbalance measurement is carried out, which then determines the further course of the spin program.
  • the fluctuations in the current consumption or the speed of the washing and centrifugal drum drive motor are evaluated as an indication of a possible imbalance of the washing and centrifuging drum. If an unbalance greater than the entered unbalance size limit value is determined, the drive motor is controlled via a speed control device such that the items to be washed or centrifuged can be redistributed. If this does not lead to success after several attempts, the speed is reduced to a lower speed.
  • a disadvantage of the known method is that the imbalance detection is very inaccurate and does not guarantee an optimal centrifugal process under all possible operating conditions.
  • the invention is based on the object of addressing a method for correcting the unbalance size limit value, by means of which an automatic optimization to a maximum spin speed and thus optimal dewatering of the spin or laundry items with low or minimal laundry item imbalance in the washing and spin dryer drum is achieved .
  • the object is achieved according to the invention in that the actual value fluctuations in the drive motor speed are determined during the centrifugal material distribution phase and in that the unbalance size limit value entered in the program control unit is corrected on the basis of the parameters entered into the program control unit, such as the type of laundry and quantity of laundry, or on the basis of the measured quantity of laundry and the type of laundry entered.
  • the actual value fluctuations in the speed of the drive motor for the washing and centrifuging drums, which are determined during the distribution phase of the centrifuged material thus represent the measure or the unbalance variable for the centrifugal material distribution.
  • the actual value fluctuations of the speed are the smaller, the greater the individual unbalance symmetrical base load and spin speed in the washing and spinning drum.
  • This symmetrical base load is in turn dependent on the absorbency and / or the amount of the items to be washed or spun, so that the unbalance size determined with the aid of the determined fluctuations in the actual value can be corrected with a laundry type and laundry quantity correction factor which is greater than 1. This ensures that the centrifuging time is optimized in relation to the centrifuge distribution in the centrifugal drum.
