Heater-less ice maker assembly with a twistable tray

摘要

An ice maker is provided that includes a tray (50) having recesses (56) that can include ice-phobic surfaces. The ice-phobic surfaces may include ice-phobic coatings, textured metal surfaces, hydrophobic coatings or other surfaces configured to repel water and ice. The tray can be formed from metal material and may exhibit a fatigue limit greater than about 150 Megapascals (MPa) at 10 5 cycles. The ice maker further includes a frame body (40) coupled to the tray, and a driving body (44) that is rotatably coupled to the tray (50). The driving body (44) is further adapted to rotate the tray (50) in a clockwise and/or counter-clockwise cycle such that the tray (50) presses against the frame body (40) in a manner that flexes the tray (50)to dislodge ice pieces formed in the recesses (56) of the tray (50).
