Abstract

A washing machine includes a cabinet, a tub positioned within the cabinet, a basket rotatably supported within the tub, and a spray device mounted within the cabinet and positioned to introduce water into the basket. The spray device sprays an initial amount of water onto a wash load received in the basket. The rotatable basket is rotated to redistribute the wash load radially outwardly in the basket. The wash load within the basket is washed after the rotatable basket is rotated to redistribute the wash load.

Claims (22)

1. A method for redistributing a wash load held in a rotatable basket of a washing machine for promoting turnover, comprising:

spraying an initial amount of water onto the wash load from a spray device of the washing machine, the initial amount of water only without detergent is approximately 2-3 gallons to increase a mass of the wash load;

directing said initial amount of water toward a central rotational axis of said rotatable basket;

rotating the rotatable basket to redistribute the wash load radially outwardly in the basket as a result of the increased mass from the spraying step including rotating the rotatable basket at a first slower speed to ensure even water distribution to the wash load and subsequently, after said spraying of said initial amount of water, rotating said rotatable basket at a second higher speed to force the wash load radially outwardly; and

after said rotating the rotatable basket to redistribute the wash load, washing the wash load within said basket to wash the wash load.

2. The method of claim 1 wherein said rotating said rotatable basket at said second higher speed includes rapidly accelerating said basket to said second higher speed.

3. The method of claim 1 wherein said washing the wash load includes agitating the wash load within said basket to wash the wash load.

4. The method of claim 3 wherein said agitating includes agitating with a pulsator to impart rollover action to the wash load.

5. The method of claim 1 wherein said washing includes:

spraying a wash amount of water onto the wash load from said spray device for washing the wash load; and

imparting rollover action to the wash load for washing thereof.

6. The method of claim 5 wherein said rollover action includes an initial rollover and said rotating said rotatable basket to redistribute the wash load.

7. The method of claim 1 further including, after said washing of the wash load, one or both of:

spraying a rinse amount of water onto the wash load from said spray device for rinsing the wash load; and

rotating said basket to remove said rinse amount of water from the wash load.

8. The method of claim 1 wherein the first slower speed is about 15 rpm and the second higher speed is about 350 rpm.

9. A method for redistributing a wash load held in a rotatable basket of a washing machine for promoting marc rapid turnover, comprising:

imparting an initial amount of water only without detergent to the wash load toward the center of said rotatable basket and increasing the mass of the wash load with the initial amount of water;

rotating the basket at least 360 degrees at a first speed of approximately 15 RPMs to ensure even water distribution;

redistributing the wash load centrifugally within said basket by accelerating and rotating the basket to a second speed, no greater than 350 RPMs to force the wash load radially outward; and

after said redistributing, imparting rollover action to the wash load utilizing a pulsator for washing thereof.

10. The method of claim 9 wherein, the initial amount of water comprises about 2-3 gallons.
