Abstract

A refrigerator is provided comprising a cabinet, a door for providing access within the cabinet, an ice maker for making ice operably connected to the cabinet, an ice bin comprising a pair of opposite-facing walls and a bottom wall, disposed within the cabinet and located adjacent the ice maker, and a stir assembly positioned within the ice bin, comprising a stir stick, a cam rod, and a pair of breaker walls; wherein the stir stick is configured to oscillate about an axis of rotation, the cam rod is coupled to the stir stick; and the pair of breaker walls are engaged with the cam rod near the bottom of the breaker walls, and hingedly attached to the pair of opposite-facing walls.

First claim

What is claimed is:

1. A refrigerator, comprising:
a cabinet;
a door for providing access within the cabinet;
an ice maker for making ice operably connected to the cabinet;
an ice container comprising a pair of opposite-facing walls and a bottom wall having a center portion, disposed within the cabinet and located adjacent the ice maker; and
a stir assembly comprising a stir stick, a cam rod, and breaker walls and positioned within the ice container; wherein
the stir stick is configured to oscillate about an axis of rotation,
the cam rod is coupled to the stir stick; and
the pair of breaker walls are engaged with the cam rod near the bottom of the breaker walls, and hingedly attached to the pair of opposite-facing walls and move between a first position and second position in relation to the oscillating rotation of the stir stick.

2. The refrigerator of claim 1 further comprising a motor positioned under the bottom wall of the ice container.

3. The refrigerator of claim 2 wherein the stir stick is operably connected to the motor such that the motor rotates and oscillates the stir stick.

4. The refrigerator of claim 3 , wherein the stir stick comprises a rod.

5. The refrigerator of claim 4 , wherein the rod is bent along its length to protrude outwardly from the axis of rotation of the rod.

6. The refrigerator of claim 4 , wherein the stir stick is positioned at the center portion of the bottom wall.

7. The refrigerator of claim 6 , wherein the stir stick and cam rod are configured to accept a rotational motion input from the motor and deliver a linear motion output.

8. The refrigerator of claim 1 wherein the ice container is rectangular-shaped.

9. The refrigerator of claim 1 wherein the stir stick includes a bottom portion at a bottom wall of the ice container.

10. The refrigerator of claim 9 wherein the stir stick rotates about the bottom portion of the stir stick.

11. The refrigerator of claim 10 wherein the bottom portion of the stir stick extends through an aperture in the bottom wall of the ice container.

12. The ice container of claim 1 , wherein the breaker walls are attached to the pair of opposite-facing walls at a midpoint of the breaker walls.

13. The ice container of claim 1 , wherein the breaker walls are attached to the pair of opposite-facing walls at a midpoint of the opposite-facing walls.

14. An ice container, comprising:
an ice container comprising a pair of opposite-facing walls and a bottom wall, disposed within a cabinet and located adjacent an ice maker; and
a stir assembly positioned within the ice container, comprising a stir stick, a cam rod, and a pair of breaker walls; wherein
the stir stick includes a bottom portion extending through the bottom wall and is configured to rotate about the bottom portion,
the cam rod is coupled to the stir stick and is configured to accept a rotational motion input and deliver a linear motion output; and
the pair of breaker walls are engaged with the cam rod near the bottom of the breaker walls, and hingedly attached to the pair of opposite-facing walls, and move between a first position and second position in relation to the rotational movement of the stir stick.

15. The ice container of claim 14 , wherein the ice container is rectangular shaped.

16. The ice container of claim 14 , wherein the stir stick comprises a rod.

17. The ice container of claim 16 , wherein the stir stick is positioned at the center portion of the bottom wall.

18. The ice container of claim 14 , wherein the breaker walls are attached to the pair of opposite-facing walls at a midpoint of the breaker walls.

19. The ice container of claim 14 , wherein the breaker walls are attached to the pair of opposite-facing walls at a midpoint of the opposite-facing walls.

20. A method of breaking up ice within an ice container of a refrigerator, the method comprising:
providing an ice container including a first wall an opposing wall at a distance from the first wall and parallel with the first wall;
providing a stir stick operably connected to the ice container, the stir stick extending within the ice container and comprising a plurality of bends along its length;
providing a cam rod including a first end and a second end coupled with the stir stick;
providing a first breaker wall coupled with the first end of the cam rod and hingedly attached with the first wall, and a second breaker wall hingedly attached to the opposing wall and coupled with the second end of the cam rod;
rotating the stir stick within the ice container;
translating the cam rod along an axis normal to the first wall and second wall;
rocking the first breaker wall on the first wall between a first position and a second position; and
rocking the second breaker wall on the second wall between a first position and a second position.
