Definitions

the invention relates to a method for reducing the laundry imbalance in washing machines according to the preamble of claim 1.
the items to be washed are loosened before the actual spin cycle and then redistributed in accordance with a laundry imbalance correction process, i.e. the wet items of laundry must lie as evenly as possible on the inner circumference of the laundry drum.
the invention is based on the object of detecting the laundry imbalance even in the case of large laundry loads and absorbent laundry, by reducing the symmetrical base load and only throwing it up with a full target spin speed value if the value falls below a lower minimum unbalance limit.
the unbalance detection should continue to be optimized by measuring the actual engine speed fluctuations.
the washing machine shown schematically in Fig. 1 has a tub (1), a laundry drum (2) and a digital speed controller (3) for a drive motor (4).
the wash liquor is discharged using a drain pump (5) through a drain hose (6).
the drain hose (6) contains a moisture sensor (7) in the form of a water flow meter, not shown, near its elbow.
a tachometer generator (8) is driven by the drive motor (4).
the tachometer generator (8) measures the actual speed fluctuations (9) of the drive motor (4), which represent a measure of the imbalance (G) and transmits them to a microcomputer ( ⁇ P).
the spin speed setpoint value (10) is only thrown up if a prescribed minimum unbalance limit (11) and entered into the microcomputer ( ⁇ P) is not exceeded during a laundry item distribution phase or a known laundry imbalance correction system . If, on the other hand, a maximum unbalance limit is exceeded (as can be the case with large laundry loads and absorbent laundry), the laundry is redistributed in accordance with the known laundry imbalance correction system (the laundry distribution phase). If the laundry is now distributed in such a way that the maximum unbalance limit is undershot, it is spun for a certain spin time at a certain spin speed, which is, however, less than the desired spin speed value (10).
the dewatering effect of the laundry to reduce the residual moisture for the first time is measured by the moisture sensor (7) in the drain hose (6) with the help of a water quantity counter and transmitted to the microcomputer ( ⁇ P), which thereby transmits the Spin time and / or the Spin speed affected. This spin speed can also reach the desired spin speed value (10).
the microcomputer ( ⁇ P) also determines the number of wash reverse cycles during the loosening of the laundry, based on the actual speed fluctuations (9) measured by the tachometer generator (8).
the actual speed fluctuations (9) in this phase are not a measure of the imbalance (G) but a measure of the degree of loosening of the laundry.
