ABSTRACT:
A drum washing machine includes a spin basket rotatable within a tub about a horizontal axis. Projecting radially inwardly from a cylindrical wall of the spin basket is a plurality of lifters which raise clothes and then let them fall. The lifters form internal spaces into which wash water can flow. That water is raised and then flows downwardly back onto the clothes to increase washing efficiency.
