Abstract

A method for washing articles in a wash chamber of the washing machine appliance is provided. The method includes providing a tub and a basket, the basket rotatably positioned within a tub, with an amount of wash water for washing one or more articles positioned in the basket. After the wash cycle, the method initiates a spin cycle while maintaining at least a minimum amount of wash water from the wash cycle in the basket and tub. Maintaining the wash water during the initiation of the spin cycle can assist in preventing an imbalance of the wash load. For example, the wash load may be more evenly distributed during the draining of the wash water, as the wash basket is spinning during such draining of the wash water.

First claim

What is claimed is:

1. A method of washing articles in a washing machine appliance, the method comprising:
providing a tub and a basket, the basket rotatably positioned within a tub, with an amount of wash water for washing one or more articles positioned in the basket;
executing a wash cycle to wash the one or more articles positioned within the basket, wherein executing the wash cycle includes agitating the wash water, the one or more articles positioned in the basket, or both to work in the wash water and any detergent added thereto;
optionally draining a portion of the amount of wash water provided for washing the one or more articles positioned in the basket;
initiating a spin cycle subsequent to executing the wash cycle and optionally draining the portion of the amount of wash water provided for washing the one or more articles positioned in the basket, wherein initiating the spin cycle includes initiating a rotation of the basket within the tub while maintaining at least a minimum amount of wash water, V SC1 , in the basket and tub, the minimum amount of wash water, V SC1 , being at least about fifty percent of the amount of wash water provided for washing the one or more articles positioned in the basket;
executing the spin cycle; and
initiating a rinse cycle, wherein initiating the rinse cycle includes maintaining a rotational speed of at least one hundred rotations per minute from the spin cycle and providing the basket and the tub with an amount of rinse water.

2. The method of claim 1 , wherein the minimum amount of wash water, V SC1 , is at least about ninety percent of the amount of wash water provided for washing the one or more articles positioned in the basket.

3. The method of claim 1 , wherein initiating the rotation of the basket includes rotating the basket within the tub at a rotational speed of at least about one hundred revolutions per minute while maintaining at least a minimum amount of wash water, V SC1 , in the basket and tub.

4. The method of claim 1 , further
wherein executing the spin cycle includes draining wash water from one or both of the basket and the tub at a predetermined drain rate while rotating the basket within the tub.

5. The method of claim 4 , wherein the predetermined drain rate is between about 0.25 gallons per minute and about two (2) gallons per minute.

6. The method of claim 4 , wherein draining wash water from one or both of the basket and the tub at the predetermined drain rate includes activating a drain pump of the washing machine appliance.

7. The method of claim 1 , further comprising
optionally draining a portion of the amount of wash water provided to the basket and the tub during the initiation of the rinse cycle; and
initiating a second spin cycle subsequent to initiating the rinse cycle and optionally draining the portion of the amount of wash water provided to the basket and the tub during the initiation of the rinse cycle, wherein initiating the second spin cycle includes initiating a rotation of the basket within the tub while maintaining at least a minimum amount of wash water, V SC2 , in the basket and tub, the minimum amount of wash water, V SC2 , being at least about fifty percent of the amount of water provided to the basket and tub during the initiation of the rinse cycle.

8. The method of claim 7 , wherein initiating the rotation of the basket during the step of initiating the second spin cycle includes rotating the basket within the tub at a rotational speed of at least about one hundred revolutions per minute while maintaining at least a minimum amount of wash water, V SC2 , in the basket and tub.

9. The method of claim 1 , wherein providing the tub and the basket with the amount of wash water comprises providing the tub and the basket with a total amount of wash water, and wherein the minimum amount of wash water, V SC1 , is at least about fifty percent of the total amount of wash water provided for washing the one or more articles positioned in the basket.

10. A washing machine appliance comprising
a tub;
a basket rotatably positioned within the tub; and
a controller configured to
provide the tub and the basket with a total amount of wash water for washing one or more articles positioned in the basket;
execute a wash cycle to wash the one or more articles in the basket, wherein in executing the wash cycle the controller is configured to agitating the wash water, the one or more articles positioned in the basket, or both to work in the wash water and any detergent added thereto;
optionally drain a portion of the amount of wash water provided for washing the one or more articles positioned in the basket;
initiate a spin cycle subsequent to executing the wash cycle and optionally draining the portion of the amount of wash water provided for washing the one or more articles positioned in the basket, wherein initiating the spin cycle includes initiating a rotation of the basket within the tub while maintaining at least a minimum amount of wash water, V SC1 , in the basket and tub, the minimum amount of wash water, V SC1 , being at least about fifty percent of the amount of wash water provided for washing the one or more articles positioned in the basket;
execute the spin cycle; and
initiate a rinse cycle, wherein initiating the rinse cycle includes maintaining a rotational speed of at least one hundred rotations per minute from the spin cycle and providing the basket and the tub with an amount of rinse water.

11. The washing machine appliance of claim 10 , wherein the minimum amount of wash water, V SC1 , is at least about ninety percent of the amount of wash water provided for washing the one or more articles positioned in the basket.

12. The washing machine appliance of claim 10 , wherein in initiating the rotation of the basket, the controller is configured to rotate the basket within the tub at a rotational speed of at least about one hundred revolutions per minute while maintaining at least a minimum amount of wash water, V SC1 , in the basket and tub.

13. The washing machine appliance of claim 10 , wherein in executing the spin cycle, the controller is configured to drain the wash water from one or both of the basket and the tub at a predetermined drain rate subsequent to initiating a rotation of the basket within the tub.

14. The washing machine appliance of claim 13 , wherein the predetermined drain rate is between about 0.25 gallons per minute and about two (2) gallons per minute.

15. The washing machine appliance of claim 13 , wherein in draining wash water from one or both of the basket and the tub at the predetermined drain rate the controller is configured to activate a drain pump of the washing machine appliance.

16. The washing machine appliance of claim 10 , wherein the controller is further configured to
optionally draining a portion of the amount of wash water provided to the basket and the tub during the initiation of the rinse cycle; and
initiate a second spin cycle subsequent to initiating the rinse cycle and optionally draining the portion of the amount of wash water provided to the basket and the tub during the initiation of the rinse cycle, wherein initiating the second spin cycle includes initiating a rotation of the basket within the tub while maintaining at least a minimum amount of wash water, V SC2 , in the basket and tub, the minimum amount of wash water, V SC2 , being at least about fifty percent of the amount of water provided to the basket and tub during the initiation of the rinse cycle.
