ABSTRACT:
A clothes washing machine includes a washing tub, a drum rotatably arranged within the tub and adapted to hold the washload, and a liquor recovery reservoir, separable from the structure of the machine. A liquor transfer conduit connects the lower portion of the washing tub with the inner volume of the reservoir, preferably through a first pump situated in the conduit. A second conduit connects the inner volume of the reservoir with the inner volume of the washing tub through a second pump. As a part of a rinsing phase, the machine is adapted to the rinsing liquor from the tub to the reservoir, spin the washload holding drum at a high revolution speed, empty the tub by draining the liquor extracted from the washload during the high-speed spinning of the drum or subsequently thereto, and transfer the liquor contained in the reservoir back into the tub.
