METHOD OF WASHING AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 1996 - IPC

FIELD: vibration methods of washing and machines intended for washing of cloth of any fabric. SUBSTANCE: the method of washing consists in creation of vibrations and flows of liquid in a detergent. Vibrations are created in the form of shock waves directed towards the detergent free surface. Liquid flows are produced by formation of transverse compressions waves. Shock and transverse waves are obtained by means of one motion of a common working (radiating) surface. The washing device uses a tank of dielectric material, active metal plate mounted in a rubber ring around the edges, and a vibrator made in the form of an electrodynamic energy converter. The latter uses a field structure in the form of a flat insulated spiral installed in the exciting unit case, consisting of a power source and a pulse generator. Positioned on the metal plate surface facing the detergent free surface are bosses having in cross- section the shape of non-isosceles triangles with different relationships of angles at their bases. EFFECT: facilitated procedure. 2 cl, 3 dwg
