Abstract
An automatic washing machine having a imperforate stationery tub and further having a rotatable plastic wash basket, for receiving a clothes load, disposed within the tub. The rotatable plastic wash basket includes a cylindrical outer wall defining a vertical axis and having an upper end open for receiving the clothes load. A base integral with the cylindrical outerwall is provided for forming a bottom of the rotatable basket. A hub member is positioned centrally in the base and is drivingly connectable with a drive shaft for rotating said rotatable wash basket. The base further includes an annular cavity, formed within the base, surrounding the hub member. The annular cavity has a substantially triangular radial cross-section such that the base comprises walls which define the annular cavity and form a triangular truss optimally configured for providing strength and rigidity to the wash basket base.
