WASHING-WRINGING MACHINE Russian patent published in 2010 - IPC D06F23/02 D06F37/02 

FIELD: textile, paper.

SUBSTANCE: washing-wringing machine comprises external drum with cover, inside of which there is coaxially installed internal drum with frame made of longitudinal ribs, which are rigidly fixed with one end on its end wall, shell attached to it, and neck with hole for laundry loading and unloading. Frame of internal drum is arranged in the form of spatial closed symmetrical polyhedral figure, at one end it is opened, and at the opposite end it has solid flat stiff wall. Longitudinal ribs are rigidly fixed with their one end on wall coaxially to axis of rotation in two rows, one of which is external, and the other one - external. Number of ribs in each row is identical, and they are arranged at equal distance from each other. Each rib in inner row is equidistant from two neighbouring ribs of external row. At open end in external row each rib with its other end is rigidly connected to according ends of adjacent ribs by means of connection elements. Each rib of inner row with its other end is rigidly connected to ends of two neighbouring ribs of external row by means of links. Shell of inner drum represents laundry basket made of two rigid end walls and cylindrical shell rigidly connected to them. Each of end walls is arranged in the form of convex polyhedron, identical to polyhedron in cross section of frame. One of end walls of basket is coupled with end wall of frame and is rigidly connected to it, and its other end wall with hole for laundry loading and unloading is fixed on frame at open end and is neck of inner drum. Cylindrical shell of laundry basket by means of fixing elements is rigidly fixed on each of frame ribs at outer side.

EFFECT: simplified design and reduced metal intensity of inner drum, which makes it possible to reduce prime cost of washing and wringing machine manufacturing.
