WASHING MACHINE OF DRUM TYPE Russian patent published in 2012 - IPC D06F39/00 

FIELD: textile, paper.

SUBSTANCE: washing machine comprises a body, a washing unit, comprising a washing tank and a drum installed coaxially inside the tank as capable of rotation around the horizontal axis. The washing tank comprises inner and outer cylindrical reservoirs, a system of vibration insulation from springs of washing unit suspension and vibration dampers. Holes of perforation of inner and outer cylindrical reservoirs of the drum are arranged opposite to each other and are connected by means of elastic tight channels. Drum reservoirs are connected to each other by elastic tight elements, arranged near end edges of reservoirs, to form a closed tight cavity filled with working fluid between walls of inner and outer cylindrical reservoirs of the drum. The rotation torque of the outer cylindrical reservoir of the drum is transferred from the motor via the shaft, and of the inner reservoir - via helical springs, having the necessary radial and longitudinal stiffness and installed at ends of the inner reservoir outside the closed tight cavity and rigidly joined with both cylindrical reservoirs and the drum.

EFFECT: lower level of vibration in the period of centrifugal wringing of articles, improved manufacturability of structure assembly, reduction of dimensions, lower impact loads during rotation of a drum when washing and in process of wringing.
