Abstract
Disclosed herein is a washing machine which comprises a bubble generator operable to supply a predetermined amount of air bubbles into the washer tub in a batchwise manner at such a time interval as to allow said amount of air bubbles supplied in a preceding batch to be substantially collapsed before a next supply of said air bubbles commences.
Claims8
A washing machine which comprises:
- a washer tub capable of containing a level of washing fluid;
- a pulsator rotatably mounted on the bottom of said washer tub for creating a vortex flow within said washer tub;
- means for causing said pulsator to rotate in a foward or reverse direction;
- and
- means for supplying a predetermined amount of air bubbles into said washer tub in a batchwise manner at such a time interval as to allow said amount of air bubbles supplied in a given batch to be substantially collapsed before a next supply of said air bubbles commences, wherein said bubble supply means includes an air pump for producing a volume of pressurized air, a bubble generator associated with said air pump for converting the pressurized air into Said air bubbles, and means for controlling the operation of said air pump so that no air bubbles may be supplied until said amount of air bubbles supplied in a preceding batch is substantially collapsed.
A washing machine of claim wherein said coefficient of bubble supply, .alpha., ranges from 0.55 to 0.68 and said reference bubble quantity, .beta., is equal to one tenth of the volume of the washing fluid.
