1. A fabric washing appliance comprising:

  • a tub;

    a fabric receiving basket;

    recirculating means arranged to deliver liquid from said tub to said basket; and

    liquid supply means for delivering liquid to said basket;

    said basket having formed therein a plurality of individual vertically spaced flow means, each one of said flow means being constructed and arranged to permit liquid flow from said basket to said tub through said one of said flow means at a predetermined unimpeded flow rate when the level of fabrics in said basket is lower than said one flow means and to permit liquid flow through said one of said flow means at a lower, impeded flow rate when the level of fabrics in said basket is above said one of said flow means, the unimpeded flow rate through said one of said flow means, in combination with the cumulative impeded flow rate of any flow means lower than said one of said flow means, providing a total flow rate from said basket to said tub at least equal to the rate of flow of liquid into said basket from said liquid supply means and said recirculating means, the cumulative impeded flow rate through all of said flow means providing a total flow rate from said basket to said tub which is less than the flow rate of said recirculating means thereby stabilizing the liquid level in said basket at approximately the level of the lowermost flow means through which flow is unimpeded by the fabric in said basket, whereby the liquid level in the basket is automatically determined by the level of fabric in said basket.
