of cabinet 12 by a conventional hung strut suspension system 36 which is of known construction and does not comprise part of the instant invention the washing assembly also includes one or more agitators 38 that operate in a manner as described in u s pat no 6 220 063 to wunderlich on apr 24 2001 during the washing action rotation of shaft 24 causes clutch 26 to simultaneously disengage hub 28 from shaft 24 and secure hub 28 against rotation this enables shaft 24 to rotate freely within hub 28 to drive the agitators 38 while also preventing rotation of basket 30 after the washing cycle has completed the motor 18 is reversed causing a reverse rotation of shaft 24 this reverse rotation of shaft 24 causes clutch 26 to couple the shaft 24 to the hub 28 while simultaneously allowing free rotation of hub 28 thereby causing the basket 30 to rotate for the spin cycle during the spin cycle the washing fluid passes outwardly through perforations 32 and into the tub 34 due to centrifugal force 0026 fig2 shows the tub 34 of the present invention the tub 34 includes a lower portion 40 and an upper portion 42 the inner wall of the upper portion 42 includes one or more grooves 44 as is shown in fig4 as shown in fig2 the groove 44 preferably runs along the entire upper portion of the tub 34 but may be of any length width or depth as desired the groove 44 also preferably runs in a generally vertical direction though it may be angled or even spiral around the inside wall of the tub 34 as shown in fig3 preferably the tub 34 is made of a plastic material.
