The article deals with the processes and forces that arise during the interaction of the material with the components of the drum of the washing machine at a high speed of rotation that occurs during the spin operation. In consumer services in drum washing machines during rotating drum washing mode is performed mechanical effect on the treated material and it’s mixing, which also provides hydrodynamic activation of the washing solution. It was analysed that the emergence of a drum imbalance as a result of uneven distribution of the processed material substantially limits the possibility of further spinning at an increased frequency of rotation. The regularities of the material distribution on the surface of the shell are investigated. Shown the change of the forces which are acting on the accelerated rotation of the drum as a result of the interaction of surfaces of the lateral faces of the paddles and the treated material, with the change in the side faces of the angle of inclination. The forces that arise at the point of contact of the material and the paddles of the drum of the washing machine are considered. It was investigated that at accelerated rotation of the drum, the material always interacts only with the same surface of the paddle. Considered the conditions that must be ensured for moving the processed element of the material along the surface of the lateral face of the drum paddle. The variants of interaction of material with paddles of various forms are analyzed. Described that at high angles of side edges, without reducing the height of the ridges decreases useful internal volume of the drum due to increased volume, dealing with these ridges. The interconnection of the parameters of the geometric shape of the paddles of the tub and the mode of its rotation is obtained, which allows to find a rational relationship between them and, thus, to increase the efficiency of the spin cycle.
