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;
a rotating tub rotatably installed in the water tub;
a driver connected to the rotating tub and configured to rotate the rotating tub;
a balancer disposed at an upper portion of the rotating tub, the balancer comprising a bottom configured to block a portion of wash water moving upward in the rotating tub during operation of the washing machine; and
a rib disposed in only the bottom of the balancer and integrally formed with the bottom of the balancer, wherein the rib is configured to at least partially block wash water moving in a substantially horizontal direction.

2. The washing machine of claim 1 , wherein
the rib extends inwardly in a radial direction of a central axis of the rotating tub.

3. The washing machine of claim 2 , wherein
a length of the rib in a direction of the central axis of the rotating tub is no longer than a length of the bottom of the balancer.

4. The washing machine of claim 2 , wherein
the rib has a substantially rectangular cross section along a radial direction of the central axis of the rotating tub.

5. The washing machine of claim 2 , wherein
the rib has a substantially rectangular lateral cross section.

6. The washing machine of claim 1 , wherein
the rib extends in a longitudinal direction of the rotating tub from the bottom of the balancer.

7. The washing machine of claim 1 , wherein
a bottom of the rib is substantially parallel to a bottom of the rotating tub.

8. The washing machine of claim 1 , wherein
the rib integrally formed with the bottom of the balancer is one of a plurality of ribs arranged at a same interval.

9. The washing machine of claim 1 , wherein
the rib integrally formed with the bottom of the balancer is one of a plurality of ribs disposed above through holes of the rotating tub.

10. The washing machine of claim 1 , wherein
one end of the bottom of the balancer contacts the rotating tub and an opposite end of the bottom of the balancer does not contact the rotating tub.

11. The washing machine of claim 1 , wherein
the bottom of the balancer is substantially parallel to a bottom of the rotating tub.

12. The washing machine of claim 1 , wherein
the bottom of the balancer is substantially perpendicular to a lateral surface of the rotating tub.

13. The washing machine of claim 1 , wherein
the balancer includes a liquid material.

14. A washing machine comprising:
a water tub;
a rotating tub rotatably installed in the water tub;
a driver connected to the rotating tub and configured to rotate the rotating tub;
a balancer disposed at an upper portion of the rotating tub; and
a deviation preventer comprising a plurality of ribs configured to prevent abnormal vibration from occurring in the rotating tub,
wherein the plurality of ribs of the deviation preventer are disposed in only a bottom of the balancer.

15. The washing machine of claim 14 , wherein
the plurality of ribs are integrally formed with the bottom of the balancer to at least partially block movement of wash water.

16. The washing machine of claim 14 , wherein
ribs of the plurality of ribs extend in a radial direction of a central axis of the rotating tub.

17. The washing machine of claim 14 , wherein
ribs of the plurality of ribs extend in a longitudinal direction of the rotating tub.

18. The washing machine of claim 14 , wherein
ribs of the plurality of ribs are arranged with a same interval.

19. The washing machine of claim 14 , wherein
the plurality of ribs are formed at the upper portion of the rotating tub and contact the bottom of the balancer.

20. The washing machine of claim 14 , wherein
the bottom of the balancer is substantially parallel to a bottom of the rotating tub.
