Abstract

An ice making device provides an ice tray and a frame to hold the ice tray. The frame has a proximal end with a motor and a distal end with a circular opening. An insert positioned in the circular opening with a projection provides a vibrating motion to dislodge ice cubes from the ice tray. An ice tray includes an integrated heating circuit for sensing capacitance and releasing frozen ice cubes. An ice tray also includes a raised flange to prevent water from splashing out of the ice tray.

Claims (14)

1. An icemaker comprising:

an ice tray;

a frame adapted to hold the ice tray, the frame having a proximal end and a distal md having a circular opening, wherein the circular opening includes a plurality of protrusions along an inner perimeter of the circular opening; and

an insert positioned in the circular opening of a side of the frame, wherein the insert further comprises a projection positioned relative to a circumference of the insert, wherein the insert is further adapted to rotate inside the circular opening of the frame and wherein the projection of the insert is adapted to engage with the plurality of protrusions of the circular opening during rotation of the insert.

2. The icemaker of claim 1 wherein the insert comprises a slot and wherein the slot is configured to hold an edge of the ice tray.

3. The icemaker of claim 2 wherein the insert is further adapted to rotate the ice tray when the slot holds the edge of the ice tray.

4. The icemaker of claim 1 wherein the protrusions are arranged in a lower portion of the opening.

5. The icemaker of claim 4 wherein the protrusions are arranged within a single quadrant of the opening.

6. A method for utilizing an icemaker, the method comprising:

inserting an ice tray within a frame of the icemaker,

freezing water deposited in the ice tray;

engaging at least one edge of the ice tray with a rotatable insert positioned within the frame;

rotating the insert and the ice tray upon a formation of ice within the ice tray; and

engaging a projection on a circumference of the rotatable insert with a plurality of protrusions on the frame as the insert rotates relative to the frame to vibrate the ice tray during rotation of the insert and dislodge a plurality of ice cubes from the tray.
