Tub and drum of a washing-machine

Claim 1

A laundry washing and spin-drying machine having a high ratio of drum volume to housing width, comprising a housing, a tub, means for resiliently mounting said tub within said housing, a drum mounted within said tub for rotation about a horizontal axis, means for driving said drum at agitating speed for washing and at high speed for spin-drying, and means for obtaining access to the interior of the drum to insert and remove laundry, said tub comprising: a cylindrical part having two end edges; two flanks, each of said flanks comprising a truncated conical surface extending outward, said truncated surface having a large base edge and a small base edge, said base edges lying in parallel planes, the large base edge of each flank adjoining a respective end edge of the cylindrical part, each flank further comprising a substantially planar surface having an outer edge fixed to said small base edge; and means for fixing each large base edge to the respective end edge, said fixing means being entirely located inwardly of the plane in which said small base edge lies, whereby said fixing means has adequate clearance from said housing despite angular movements of said axis due to laundry unbalance during spin-drying.
