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 stationary tub. The rotatable plastic wash basket further includes a cylindrical outer wall having an upper end open for receiving the clothes load. A base integral with the cylindrical outer wall is provided for forming a bottom of the rotatable basket. An annular core member is disposed within the base of the plastic wash basket such that the base encapsules and interlocks with the annular core member. In addition, a hub member is disposed centrally in the annular core member and is drivingly connectable with a drive shaft for drivingly rotating said rotatable wash basket. The annular core member has a substantially triangular radial cross-section such that the base is optimally configured to form a solid triangular radial cross-section for providing strength and rigidity to the wash basket. Alternately, a combined core member may be disposed within the base, combining the function of the hub member and the annular core member into one integral member.
