Method for washing laundry in a laundry washing machine and laundry washing machine

摘要

The present invention relates to a method for washing laundry in a laundry washing machine (1; 200; 300) of the type comprising: a washing tub (3) external to a rotatable washing drum (4) adapted to receive laundry; a water supply circuit (5) to supply water into the washing tub (3); a washing/rinsing products supplier (6) to supply washing/rinsing products (D) into the washing tub (3); a heater device (10) placed at the bottom (3a) of the washing tub (3) for heating a liquid coming into contact with it; a recirculation circuit (20) suitable for withdrawing liquid from a bottom region (3a) of the washing tub (3) and for re-admitting such a liquid into the washing tub (3) in such a way that the re-admitted liquid wets the laundry. The method comprises the steps of: introducing (120) a quantity (Qd) of a washing/rinsing product (D) and a quantity (Q1 w ) of liquid (W) into the washing tub (3); decreasing the liquid level inside the washing tub (3) by activating (130) the recirculation circuit (20) for withdrawing liquid (S) from the washing tub (3) and re-admitting the liquid into the washing tub (3) in such a way that the re-admitted liquid wets the laundry; detecting the liquid level inside the washing tub (3) and, if the liquid level reaches a threshold level (Lm, Lb) which is below the heater device (10): deactivating (140) the recirculation circuit (20); introducing (150) into the washing tub (3) a quantity (Q1' W ) of liquid (W') in such a way that the quantity (Q1' w ) of liquid (W') falls at the bottom (3a) of the washing tub (3) and strikes the liquid present therein so as to improve the dissolution of the washing/rinsing product (D) collected therein.
