Laundry appliance

Abstract

A laundry machine configured to supply a first amount of water to the wash tub wherein a wash plate can be oscillated such that clothes items directly above and in contact with the impeller are frictionally dragged in a oscillatory manner with the wash chamber while continuing to oscillate said wash plate, an additional supply of water is added to said wash tub such that as cloth items lost frictional engagement with the wash plate, the cloth items continue to move along an inverse toroidal rollover path at higher water levels.

1 . A laundry machine comprising:
 a cabinet;   a wash tub supported within the cabinet;   a motor suspended beneath the wash tub;   a wash basket rotatably supported within the wash tub and being drivingly connected to the motor;   a wash plate disposed in the bottom of the wash basket and driving the connector to the motor; and   a controller controlling supply of water to said wash tub and driving of said wash plate by said motor, such that a first amount of water is supplied to said wash tub, said wash plate is oscillated such that clothes items directly above and in contact with the impeller are frictionally dragged in a oscillatory manner and the cloth items roll over within the wash chamber along an inverse toroidal rollover path, and while continuing to oscillate said wash plate, an additional supply of water is added to said wash tub such that as cloth items lose frictional engagement with the wash plate, the clothing continues to move along an inverse toroidal rollover path at higher water levels.   
     
     
         2 . A laundry machine as claimed in  claim 1 , wherein said controller controls said motor to drive said wash plate in an initial drive profile when commencing a wash phase, and subsequently in a maintenance drive profile, and said initial drive profile is characterised by longer strokes and/or higher angular velocities than said maintenance drive profile. 
     
     
         3 . A laundry machine comprising:
 a cabinet;   a wash tub supported within the cabinet;   a motor suspended beneath the wash tub;   a wash basket rotatably supported within the wash tub and being drivingly connected to the motor;   a wash plate disposed in the bottom of the wash basket and driving the connector to the motor; and   a controller controlling supply of water to said wash tub and driving of said wash plate by said motor, said controller having:   a first operating mode wherein an amount of water is supplied to said wash tub, said wash plate is oscillated such that clothes items directly above and in contact with the impeller are frictionally dragged in a oscillatory manner and the cloth items roll over within the wash chamber along an inverse toroidal rollover path, and the amount of water in said wash tub is not substantially increased through the wash portion of a wash cycle;   
       and a second operating mode—wherein a first amount of water is supplied to said wash tub, said wash plate is oscillated such that clothes items directly above and in contact with the impeller are frictionally dragged in a oscillatory manner and the cloth items roll over within the wash chamber along an inverse toroidal rollover path, and while continuing to oscillate said wash plate, an additional supply of water is added to said wash tub such that as cloth items lose frictional engagement with the wash plate, the clothing continues to move along an inverse toroidal rollover path at higher water levels. 
     
     
         4 . A laundry machine as claimed in  claim 3 , wherein said controller controls said motor to drive said wash plate in an initial drive profile when commencing a wash phase, and subsequently in a maintenance drive profile, and said initial drive profile is characterised by longer strokes and/or higher angular velocities than said maintenance drive profile.
