DRUM-TYPE WASHING MACHINE Russian patent published in 2007 - IPC D06F33/02 

FIELD: mechanical engineering.

SUBSTANCE: drum-type washing machine has rotating drum, external tank wherein drum is fixed, drive electric engine, detergent department, first water supply means for supplying of water into external tank through detergent department, second water supply means for supplying of water into rotating drum through its front opening, and controller for controlling operation of drive electric engine and first and second water supply means. Washing process is performed so that water is initially supplied to second water level by means of first water supply means. Drum is rotated at first rotational velocity creating centrifugal force urging cloths to be pressed to drum surface. Drum is then rotated at second rotational velocity during supplying of water to first water level by means of second water supply means. Second water level is lower than first water level. At second rotational speed of drum, cloths are lifted to further drop by gravity. At second water level, the lowest part of drum is under water surface.

EFFECT: increased efficiency and improved quality of washing cloths.
