Abstract

The present invention relates to a laundry washing machine (1) comprising a washing tub (3) external to a rotatable washing drum (4) adapted to receive laundry. The machine further comprises a water supply circuit (5) to supply water into the washing tub (3), a washing/rinsing products supplier (6) to supply washing/rinsing products into the washing tub (3), a liquid outlet circuit (25) suitable for withdrawing liquid from the washing tub (3) and to convey such a liquid to the outside. The machine further comprises a first recirculation circuit (20) suitable for withdrawing liquid from the washing tub (3) and to re-admit such a liquid into a first region (3b) of said washing tub (3), wherein the first recirculation circuit (20) comprising a first recirculation pump (21) suitable for forcing liquid inside the first recirculation circuit (20) and a second recirculation circuit (30) suitable for withdrawing liquid from the washing tub (3) and to re- admit such a liquid into a second region (3c) of the washing tub (3). The second recirculation circuit (30) comprises a second recirculation pump (31) suitable for forcing liquid inside the second recirculation circuit (30).
