Twist harvest ice geometry

A refrigerator comprising:

• an ice maker having an ice tray, the ice tray comprising:
• a rigid plate having a top surface;
• and
• a flexible grid having (i) a median wall dividing the ice tray into at least two reservoirs, (ii) dividing walls, and (iii) an edge wall;
• wherein, the median wall, the dividing walls, and the edge wall all extend from the top surface of the rigid plate when the flexible grid is in an ice piece formation position;
• wherein, the median wall, the edge wall, the dividing walls, and the top surface of the rigid plate define an array of individual compartments to receive water and form ice pieces while the flexible grid is in the ice piece formation position;
• wherein, the individual compartments diverge outwardly such that the formed ice pieces have an upper surface area that is greater than a lower surface area;
• wherein, the individual compartments have a height of about 9 mm to about 14 mm;
• and
• wherein, after ice pieces are formed in the array of individual compartments, the ice tray is inverted and the flexible grid is twisted such that the ice pieces in the individual compartments are separated from the flexible grid and fall out of the ice tray.

An ice tray for an ice maker comprising:

• an ice forming plate with a top surface and a bottom surface;
• a containment wall that surrounds the top surface of the ice forming plate and extends upwards from the ice forming plate, the containment wall having a first sidewall and a second sidewall opposing the first sidewall, the containment wall configured to retain water on the top surface of the ice forming plate;
• a flexible grid without a bottom, the flexible grid being separable from the ice forming plate and the containment wall, the flexible grid comprising:
• (i) a median wall that extends from the top surface, dividing the ice tray into a first reservoir between the median wall and the first sidewall of the containment wall and a second reservoir between the median wall and the second sidewall of the containment wall;
• (ii) edge walls;
• and (iii) dividing walls extending from the top surface of the ice forming plate, wherein the median wall, the edge walls, and the dividing walls have a draft angle of 17° to 25° from vertical;
• and
• individual ice forming compartments defined by the median wall of the flexible grid, the dividing walls of the flexible grid, and the ice forming plate forming a bottom of the individual ice compartments.
