Patent ID: 8528350

Claim:
An ice making apparatus, comprising: an ice making tray in which ice is made; an ejector that discharges the ice made in the ice making tray into an ice bank; a cam assembly cooperatively coupled to the ejector, the cam assembly including a driving cam coupled to the ejector, a lever that rotates with the driving cam, and a gear assembly that rotates with the lever; an ice full detecting arm that is rotated by the cam assembly to detect if the ice bank is fully filled with the ice, the ice full detecting arm being coupled to the gear assembly via a rotational shaft and concurrently rotatable with the gear assembly; a first ice full detector that detects a position of the cam assembly when the cam assembly operates, the first ice full detector including a first magnet and a first sensor; and a second ice full detector, which is a separate detector from the first ice full detector, that detects if the ice full detecting arm is not returned to an initial position by being caught on the ice, the second ice full detector including a second magnet and a second sensor, wherein the second sensor is aligned with the second magnet detecting when the ice full detecting arm is returned to the initial position, while the second sensor misses the second magnet so as not to detect when the ice full detecting arm is caught on the ice.
