Abstract
A plastic washtub used preferably in household clothes washing machines having a rigid structure (1) formed by a cylindrical wall (2 ), a circular bottom wall (3 ), and a circular front wall. A hub (6) is inserted through the central part of the bottom wall. It is called a hub because it is inserted into a central circular hub-housing (7) of the bottom wall (3) and supports the central shaft (11 ) of the rotor (8 ) in a known manner. This hubhousing's central portion (7) has around and adjacent to it one or more closed, empty chambers so that the hub-housing (7) does not enter into contact with the washing liquid. It is preferred that, inside the tub, said hub-housing (7) be protected by a plate (15), preferably of plastic, which is attached to ribs on the bottom wall to prevent the washing liquid from directly contacting the hub-housing.
