Abstract

An ice maker may include an assembly frame, an ice tray, a cam, a splash cover, and a biasing spring. The ice tray may define a cell for receipt of water for freezing and may be rotatably attached to the assembly frame to rotate about an axial direction. The cam may be attached to the ice tray and extend along the axial direction. The splash cover may be slidably attached to the assembly frame in mechanical communication with the cam to move between an elevated position and a lowered position according to a rotational position of the cam. The biasing spring may be disposed on the splash cover and urge the splash cover to the lowered position.

First claim

What is claimed is:

1. An ice maker comprising:
an assembly frame;
an ice tray defining a cell for receipt of water for freezing, the ice tray being rotatably attached to the assembly frame to rotate about an axial direction;
a cam attached to the ice tray to rotate therewith, the cam extending along the axial direction;
a splash cover slidably attached to the assembly frame in mechanical communication with the cam to move between an elevated position and a lowered position according to a rotational position of the cam; and
a biasing spring disposed on the splash cover, the biasing spring urging the splash cover to the lowered position,
wherein the ice maker comprises a plurality of springs disposed on discrete locations of an upper surface of the splash cover to collectively urge the splash cover to the lowered position, and wherein the biasing spring is one spring of the plurality of springs,
wherein the plurality of springs comprises a pair of springs disposed on opposite radial sides and proximal to opposite axial ends of the splash cover to prevent rotation of the splash cover during movement between the elevated position and the lowered position,
wherein the ice tray extends along the axial direction between a first body wall and a second body wall, wherein the ice tray is rotatable about the axial direction between a horizontal receiving position corresponding to the lowered position and a deformed evacuation position, wherein the horizontal receiving position provides the first body wall in circumferential alignment with the second body wall to permit receipt of water within the cell, and
wherein the deformed evacuation position provides the first body wall in circumferential offset with the second body to permit removal of ice from the cell.

2. The ice maker of claim 1 , wherein the splash cover comprises an arcuate outer wall segment extending partially about the axial direction.

3. The ice maker of claim 1 , wherein the splash cover comprises a pair of outer wall segments disposed at opposite radial sides of the assembly frame, and wherein the pair of outer wall segments is disposed radially outward from the ice tray.

4. The ice maker of claim 3 , wherein the splash cover further comprises an intermediate wall segment extending between the pair of outer wall segments, and wherein the intermediate wall segment defines a central passage through which water may be received upstream from the cell.

5. The ice maker of claim 1 , wherein the biasing spring is mounted above the ice tray and at least a portion of the splash cover.

6. The ice maker of claim 1 , wherein the assembly frame extends along the axial direction between a first frame end and a second frame end, and wherein the assembly frame comprises a frame stop at the first frame end, the frame stop being engaged with the first body wall in the deformed evacuation position to halt uni-directional rotation at the first body wall.

7. The ice maker of claim 1 , wherein the ice tray further comprises a first radial side and a second radial side extending between the first body wall and the second body wall, and wherein the splash cover comprises an outer wall segment having an outer surface and an inner surface, the outer surface facing away from the axial direction and radially outward therefrom, the inner surface facing toward the axial direction and defining a radial lip extending along a top surface of the first radial side in the horizontal receiving position.

8. An ice maker comprising:
an assembly frame;
an ice tray defining a cell for receipt of water for freezing, the ice tray being rotatably attached to the assembly frame to rotate about an axial direction;
a cam attached to the ice tray to rotate therewith, the cam extending along the axial direction;
a splash cover slidably attached to the assembly frame in mechanical communication with the cam to move along a non-rotational, vertical path between an elevated position and a lowered position according to a rotational position of the cam; and
a plurality of springs disposed on the splash cover, the plurality of springs urging the splash cover to the lowered position,
wherein the plurality of springs comprises a pair of springs disposed on opposite radial sides and proximal to opposite axial ends of the splash cover to prevent rotation of the splash cover during movement between the elevated position and the lowered position,
wherein the ice tray extends along the axial direction between a first body wall and a second body wall, wherein the ice tray is rotatable about the axial direction between a horizontal receiving position corresponding to the lowered position and a deformed evacuation position, wherein the horizontal receiving position provides the first body wall in circumferential alignment with the second body wall to permit receipt of water within the cell, and
wherein the deformed evacuation position provides the first body wall in circumferential offset with the second body to permit removal of ice from the cell.

9. The ice maker of claim 8 , wherein the splash cover comprises an arcuate outer wall segment extending partially about the axial direction.

10. The ice maker of claim 8 , wherein the splash cover comprises a pair of outer wall segments disposed at opposite radial sides of the assembly frame, and wherein the pair of outer wall segments is disposed radially outward from the ice tray.

11. The ice maker of claim 10 , wherein the splash cover further comprises an intermediate wall segment extending between the pair of outer wall segments, and wherein the intermediate wall segment defines a central passage through which water may be received upstream from the cell.

12. The ice maker of claim 8 , wherein the plurality of springs is mounted above the ice tray and at least a portion of the splash cover.

13. The ice maker of claim 8 , wherein the assembly frame extends along the axial direction between a first frame end and a second frame end, and wherein the assembly frame comprises a frame stop at the first frame end, the frame stop being engaged with the first body wall in the deformed evacuation position to halt uni-directional rotation at the first body wall.

14. The ice maker of claim 8 , wherein the ice tray further comprises a first radial side and a second radial side extending between the first body wall and the second body wall, wherein the splash cover comprises an outer wall segment having an outer surface and an inner surface, the outer surface facing away from the axial direction and radially outward therefrom, the inner surface facing toward the axial direction and defining a radial lip extending along a top surface of the first radial side in the horizontal receiving position.
