Abstract

The present invention relates to a method for controlling a washing apparatus, and more particularly, to method for controlling a washing apparatus provided with an independently rotatable drum and a pulsator, comprising a step of draining further comprising a plurality of steps of draining a predetermined amount of rinsing water at a time; a middle step of dehydrating; and a step of supplying water, further comprising a plurality of steps of providing a predetermined amount of rinsing water at a time.

First claim

What is claimed is:

1. A method for controlling a washing apparatus comprising a drum and a pulsator which are rotatable independently, the method comprising:
a water drainage step comprising a plurality of steps configured to drain rinsing water sequentially by a predetermined amount; and then,
an intermediate spinning step following the plurality of steps of the water drainage step; and then,
a water supply step following the intermediate spinning step comprising a plurality of steps configured to supply rinsing water sequentially by a predetermined amount,
wherein in at least one of the steps provided in the water drainage step or the water supply step, at least one of the drum or pulsator is driven, and
wherein a driving time net acting ratio (a ratio of the driving time to the overall time) of the drum or pulsator is set different for each of the plurality of steps of the water drainage step or the water supply step.

2. The method for controlling the washing apparatus according to claim 1 , wherein in at least one of the steps provided in the water drainage step, at least one of the drum and pulsator is driven to separate foreign substances from clothes and the foreign substances are exhausted from the drum simultaneously to be drained together with the rinsing water.

3. The method for controlling the washing apparatus according to claim 2 , wherein at least one of the steps provided in the water drainage step, the pulsator is driven.

4. The method for controlling the washing apparatus according to claim 3 , wherein in the steps provided in the water drainage step, the rotation number (RPM) of the drum or the pulsator is set different for each of the plurality of steps of the water drainage step or the water supply step.

5. The method for controlling the washing apparatus according to claim 1 , wherein in an initial step of the steps provided in the water drainage step, the driving time net acting ratio of the pulsator is the highest in comparison to the driving time net acting ratio of the drum.

6. The method for controlling the washing apparatus according to claim 1 , wherein the driving time net acting ratio of the pulsator is getting lower, as the steps provided in the water drainage step are performed.

7. The method for controlling the washing apparatus according to claim 1 , wherein in a final step, in which a water level is lower than a predetermined water level, of the steps provided in the water drainage step, the pulsator is not driven.

8. The method for controlling the washing apparatus according to claim 1 , wherein the amount of the rinsing water drained in each of the steps provided in the water drainage step is the same.

9. The method for controlling the washing apparatus according to claim 1 , wherein the amount of the rinsing water drained in each of the steps provided in the water drainage step is different.

10. The method for controlling the washing apparatus according to claim 1 , wherein the water drainage step comprises a first drainage step, a second drainage step and a third drainage step in which the rinsing water is drained by a predetermined amount, respectively.

11. The method for controlling the washing apparatus according to claim 1 , wherein in at least one of the steps provided in the water supply step, at least one of the drum and pulsator is driven to separate foreign substances from the clothes and simultaneously to exhaust the foreign substances from the drum.

12. The method for controlling the washing apparatus according to claim 11 , wherein in an initial step, in which a water level reaches a predetermined water level, out of the steps provided in the water supply step, the drum is rotated to disperse the clothes loaded in the drum.

13. The method for controlling the washing apparatus according to claim 12 , wherein the rotation of the drum comprises a one-direction rotation or two-direction rotation.

14. The method for controlling the washing apparatus according to claim 12 , wherein in during the steps provided in the water supply step, the pulsator is driven.

15. The method for controlling the washing apparatus according to claim 1 , wherein the driving time net acting ratio of the pulsator is getting higher, as the steps provided in the water supply step are getting performed.

16. The method for controlling the washing apparatus according to claim 1 , wherein in a final step of the steps provided in the water supply step, the driving time net acting ratio of the pulsator is the highest.

17. The method for controlling the washing apparatus according to claim 1 , wherein the amount of the rinsing water supplied in the steps provided in the water supply step is the same.

18. The method for controlling the washing apparatus according to claim 1 , wherein the amount of the rinsing water supplied in the steps provided in the water supply step is different.

19. The method for controlling the washing apparatus according to claim 1 , wherein the water supply step comprises a first water supply step, a second water supply step and a third water supply step in which the rinsing water is supplied by a predetermined amount.

20. The method for controlling the washing apparatus according to claim 1 , wherein the water drainage step, the intermediate spinning step and the water supply step are performed in a rinsing cycle.
