APPARATUS FOR ABSORBING VIBRATIONS OF HOUSING AND INTERNAL PART OF DOMESTIC WASHING MACHINE WITH VERTICAL-AXIAL ROTATION OF SQUEEZING RESERVOIR Russian patent published in 2002 - IPC

FIELD: domestic washing equipment. SUBSTANCE: washing machine has apparatus for absorbing housing vibrations and balancing ring. Sleeve with spring and piston is positioned between upper and lower points of internal part and housing joint. Two stems are mounted for independent sliding inside sleeve. Rubber piston is fixed on first stem pivotally joined to housing. Lower end of second stem is pivotally joined to internal movable part. Stems are arranged in spaced relation one with respect to another. Stems axes are extending in parallel one with respect to another. All the points of internal movable part effect progressive motions, when movable part deflects from state of equilibrium. Lower end of poles- couplers is connected to upper end of internal movable part. Poles-couplers length and housing width ratio is 1: 6. Height of internal part, which is determined for the case of maximal compression of springs for poles-couplers, is calculated as difference between housing height and distance from pole-coupler and housing connection point to pole- coupler and internal movable part connection point. Balancing ring is filled with 30%-solution of ZnCl ₂. Reduced number of poles-couplers allows washing machine housing vibration to be absorbed at the stage of steady-state rotation due to reduced number of connections between housing and internal part of washing machine. EFFECT: simplified and compact construction by reduced sizes of hanger members, improved operating characteristics and increased efficiency. 7 dwg
