Abstract
A system comprising a gear having at least one slot, wherein the gear is connected to an icetray and a motor so that when the motor rotates the gear, the icetray twists, and an optical sensor that detects when the gear has rotated the slot over the optical sensor. The icetray twists while the gear is rotated in a first direction away from a home position to a reverse twist position. The rotation of gear then reverses to twist the icetray to a harvest position in a second direction that is opposite of the first direction until ice in the icetray is dislodged.
Claims16
An icemaker apparatus comprising:
- a gear having at least one slot, wherein the gear is connected to an icetray so that when the gear rotates, the icetray twists;
- an optical sensor that detects when the gear has rotated the slot over the optical sensor;
- and
- a control circuit that:
- twists the icetray while the gear is rotated in a first direction away from a home position to a reverse twist position;
- reverses the rotation of gear to twist the icetray to a harvest position in a second direction that is opposite of the first direction until ice in the icetray is dislodged.
A method for harvesting ice from an icetray of an icemaker, comprising:
- providing:
- a gear having at least one slot, wherein the gear is connected to an icetray so that when the gear rotates, the icetray twists;
- and
- an optical sensor that detects when the gear has rotated the slot over the optical sensor;
- twisting the icetray while the gear is rotated in a first direction away from a home position to a reverse twist position;
- and
- reversing the rotation of gear twists the icetray to a harvest position in a second direction that is opposite of the first direction until ice in the icetray is dislodged.
