FIELD: washing machines with vertical-axial rotation of squeezing reservoir.
SUBSTANCE: domestic washing machine has squeezing reservoir mounted for rotation relative to vertical axis, bladed activator and hollow balancing ring filled with correcting mass-liquid. Vibration suppressing apparatus has two vertical supports made in the form of tension members, whose upper ends are pivotally connected to casing and lower ends are joined to movable part of washing machine above its center of gravity. Hollow additional balancing ring is located inside squeezing reservoir. Inner part of balancing ring is communicated with squeezing reservoir cavity through metal pipe welded with its upper end to bottom of additional balancing ring casing and with its lower end to squeezing reservoir bottom. Lower end of balancing ring is arranged under liquid delivery bladed wheel and activator is fixed above bladed wheel. Blade wheel, activator and squeezing reservoir are mounted on individual drive shafts.
EFFECT: reduced vibration of washing machine casing owing to hygoscopic moment occurring at low frequencies and providing for stabilization of axis of rotation.
