LAUNDRY TREATMENT MACHINE Russian patent published in 2014 - IPC D06F37/04 

FIELD: personal usage articles.

SUBSTANCE: disclosed is a laundry treatment machine including a housing (600, 620, 630, 640) and a tank (100, 120, 130) shaping the machine visual appearance, fixed inside the casing and intended to contain water; the tank has a front section. The pressure adjustment element is designed in the form of a channel, passing through the said front section of the tank and ensuring equalisation of pressure difference in the tank and in the drum (300, 320, 340) that occurs in the course of the drum high-rate rotation due to ambient air being sucked from the tank into the drum. The drum contains a drive unit including a shaft connected to the drum, a bearing case for supporting the shaft so that to enable rotation and an electric motor for the shaft rotation as well as a flexible material preventing leakage of water from the tank in the direction of the drive unit, providing for the drive unit movement relative to the tank.

EFFECT: as a result, the volume of the laundry treatment machine tank may be increased while equalisation of pressure inside the tank and the drum prevents their possible collision during the drum rotation.
