ABSTRACT:
There is an ice tray, an ejector for ejecting ice from the tray, an ice storage bin, a mechanism for delivering ice to the tray, a bail mechanism, and a motor for driving the ejector, water delivery mechanism, and bail mechanism. The bail mechanism includes a bail and a bail switch. The motor, via the bail mechanism, raises the bail from a lower position in which the switch energizes the icemaker to an upper position in which the switch opens and the icemaker is de-energized, then permits the bail to return to the lower position if the ice bin is not full. The bail is also manually raisable to a latch-up position to manually de-energize the icemaker. A compound spring provides a bias force to return the bail to the energizing position. The spring provides a weak return force over the range in which the motor drives the bail, a strong force in the range just prior to latch-up, and an intermediate force in the intermediate range. The bail mechanism is designed so that the spring forces the bail in one direction in the three ranges mentioned above and in the opposite direction upon latch-up.
