Title: Drum washing machine with double action - has additional radially projecting details sufficiently high only to scrub linen
Inventor: OBATA YUKIO
IPC: D06F37/06
Filed: 1979-04-12
Abstract: Projections are provided on the inner surface of the drum of a domestic machine which washes and centrifuges. Some at least of these projections have a height which is less than that necessary to lift the items of linen above the axis of the drum, so that these projections at least have a scrubbing action on the linen. The linen is thus subjected to a twofold washing action since in addn. to the repeated lifting and allowing to fall, there is a scouring and rubbing action. The efficiency of the machine is increased relatively to its small size and economies of energy are made.
