Abstract

A washing machine is provided. The washing machine includes a water tub configured to be disposed in a cabinet and to store wash water, a rotating tub configured to be rotatably installed in the water tub and to include an opening formed in an upper end portion thereof, and a driver configured to be connected to the rotating tub and to rotate the rotating tub, wherein a deviation preventer configured to prevent wash water in the rotating tub from being deviated to one side during rotation of the rotating tub is formed at an upper end portion of the rotating tub.

First claim

What is claimed is:

1. A washing machine comprising:
a water tub configured to store wash water;
a rotating tub configured to be rotatably installed in the water tub and comprising an opening formed in an upper end portion thereof;
a balancer installed at a upper end portion of the rotating tub;
a deviation preventer configured to prevent abnormal vibration from occurring in the rotating tub; and
a separation preventer configured to protrude toward a central axis of the rotating tub from an inner circumference surface of the rotating tub in a circumferential direction of the rotating tub.

2. The washing machine of claim 1 , wherein the deviation preventer and the separation preventer are formed at the balancer.

3. The washing machine of claim 1 , wherein the deviation preventer comprises a plurality of ribs integrally formed with a bottom of the balancer and extending downward from the bottom of the balancer to at least partially block movement of wash water.

4. The washing machine of claim 3 , wherein the plurality of ribs is extended in a radial direction of the central axis of the rotating tub.

5. The washing machine of claim 3 , wherein the plurality of ribs is arranged with a same interval.

6. The washing machine of claim 3 , wherein the plurality of ribs is formed in a longitudinal direction of the rotating tub.

7. The washing machine of claim 3 , wherein the bottom of the balancer is substantially parallel to a bottom of the rotating tub.

8. The washing machine of claim 1 , wherein the separation preventer is continuously formed along an inner circumference surface of the balancer.

9. The washing machine of claim 1 , wherein an internal end portion of the separation preventer is formed with a curved surface having a preset curvature.

10. The washing machine of claim 1 , wherein the separation preventer is formed integrally with the balancer.

11. The washing machine of claim 1 , wherein the separation preventer comprises a plurality of through holes.

12. The washing machine of claim 11 , wherein the plurality of through holes of the separation preventer is configured to discharge wash water.

13. The washing machine of claim 11 , wherein the plurality of through holes of the separation preventer is configured to uniformly mix wash water and detergent.

14. The washing machine of claim 11 , wherein the plurality of through holes of the separation preventer is mesh shaped.

15. The washing machine of claim 1 , wherein the separation preventer comprises escaping grooves formed at opposite positions so as to pass a pulsator, configured to be detachably connected to a driver in the rotating tub, through the balancer.

16. The washing machine of claim 15 , wherein an external diameter of the pulsator is smaller than a diameter of a portion of the separation preventer in which the escaping grooves are formed.

17. The washing machine of claim 15 , wherein the escaping grooves are formed in a semicircular shape.

18. The washing machine of claim 1 , wherein the separation preventer is formed of an elastic material.
