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.

Claims (18)

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;

a driver configured to be connected to the rotating tub and to rotate the rotating tub;

a balancer disposed at an upper portion of the rotating tub; and

a separation preventer having a circular shape and configured to protrude toward a central axis of the rotating tub from an inner circumference surface of the balancer in a circumferential direction of the balancer,

wherein an external diameter of the separation preventer is approximately the same as an internal diameter of the rotating tub, and

wherein the separation preventer is formed integrally with the balancer.

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

3. 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.

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

5. The washing machine of claim 4 , wherein the plurality of through holes of the separation preventer is configured to discharge wash water.

6. The washing machine of claim 4 , wherein the plurality of through holes of the separation preventer is configured to uniformly mix wash water and detergent.

7. The washing machine of claim 4 , wherein the plurality of through holes of the separation preventer is mesh shaped.

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

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

10. The washing machine of claim 9 , 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.

11. The washing machine of claim 9 , wherein the escaping grooves are formed in a semicircular shape.
