Nugget ice maker
An ice maker includes an evaporator body, an end cap, an auger, a bearing, and a bearing cup. The end cap is mounted to the evaporator body and includes a cap bottom wall and a cap sidewall mounted to extend away from the cap bottom wall. The cap sidewall is positioned within the evaporator body. The auger includes an auger body, a connector rod, and a base. A first end of the connector rod is mounted to a first end of the auger body. The base is mounted to extend away from a second end of the auger body. The bearing is mounted to the base of the auger within the cap sidewall. The bearing cup includes an auger mounting shelf wall mounted to the base and a cup sidewall mounted to extend away from the auger mounting shelf wall. The cup sidewall surrounds the bearing and the cap sidewall.
1 . An ice maker comprising:
an evaporator body;
an end cap mounted to an end of the evaporator body, the end cap comprising a cap bottom wall, a cap shelf wall, and a cap sidewall mounted to extend away from the cap shelf wall, wherein the cap sidewall is positioned within the evaporator body, wherein the end cap further comprises a shelf that extends inward from an interior surface of the cap sidewall;
an auger comprising
an auger body mounted within the evaporator body the auger body comprising a first end and a second end that is opposite the first end;
a connector rod comprising a first rod end and a second rod end that is opposite the first rod end, the first rod end of the connector rod is mounted to the first end of the auger body and the second rod end of the connector rod is configured to mount to a motor, wherein the auger is mounted to rotate under control of the motor; and
a base mounted to extend away from the second end of the auger body;
a bearing mounted to the base of the auger within the cap sidewall of the end cap, wherein the bearing is supported by the shelf, wherein at least portions of the cap bottom wall, the interior surface of the cap sidewall, and a bottom surface of the bearing define a first air pocket to trap wear material and lubricant of the bearing; and
a bearing cup comprising an auger mounting shelf wall mounted to the base of the auger and a cup sidewall mounted to extend away from the auger mounting shelf wall, wherein the cup sidewall surrounds the bearing and the cap sidewall of the end cap, wherein the bearing cup is mounted to rotate with the auger when the auger is rotated,
wherein at least portions of the auger mounting shelf wall, the cap shelf wall, the cup sidewall, and the cap sidewall define a second air pocket to prevent fluid from reaching the bearing.
2 . The ice maker of claim 1 , further comprising an adapter mounted between the bearing and the base of the auger within the cap sidewall of the end cap to mount the bearing to the base of the auger.
3 . The ice maker of claim 2 , wherein the auger is mounted to rotate under control of the motor.
4 . The ice maker of claim 3 , wherein the adapter is mounted to rotate with the auger when the auger is rotated.
5 . The ice maker of claim 2 , wherein the adapter comprises:
an auger mounting platform, wherein the base of the auger is mounted to the auger mounting platform; and
an adapter body mounted to the auger mounting platform, wherein the bearing encircles and abuts the adapter body.
6 . The ice maker of claim 5 , wherein a pin aperture wall is formed through the auger mounting platform.
7 . The ice maker of claim 6 , further comprising an auger pin mounted within the pin aperture wall.
8 . The ice maker of claim 7 , wherein a pin channel is formed in the base of the auger, wherein the pin channel is mounted to the auger pin.
9 . The ice maker of claim 8 , wherein a bottom surface of the base of the auger is supported by a bottom wall of the auger mounting platform.
10 . The ice maker of claim 5 , wherein the adapter is mounted to rotate with the auger when the auger is rotated, wherein an inner race of the bearing is mounted to rotate with the adapter.
11 . The ice maker of claim 1 , wherein an inner race of the bearing is mounted to rotate with the auger when the auger is rotated.
12 . The ice maker of claim 1 , wherein the end cap further comprises a shelf that extends upward from the cap bottom wall, wherein the end of the evaporator body is sealed against the cap bottom wall and the shelf.
13 . The ice maker of claim 1 , wherein the cup sidewall of the bearing cup does not contact the end cap or the bearing.
14 . The ice maker of claim 1 , wherein the auger mounting shelf wall is mounted to the second end of the auger body.
15 . The ice maker of claim 1 , wherein an aperture is formed through the auger mounting shelf wall, wherein an interior surface of the auger mounting shelf wall that forms the aperture encircles and abuts the base of the auger.
16 . The ice maker of claim 1 , wherein the bearing cup further comprises a second cup sidewall mounted to the cup sidewall, wherein an interior surface of the second cup sidewall encircles and abuts the base of the auger.
