ABSTRACT:
A flexible ice tray for an automatic ice maker allowing improved temperature sensing and ice harvesting. An inverted channel is formed in the bottom wall of at least first and second ice cube sensing pockets along the tray's axis of rotation. A separate member, in the form of a rectangular sectioned block of insulation, is removably positioned on the underside of the tray and cooperates with the inverted channel to define a sensing well for enclosing a temperature sensor tube positioned on the rotational axis. The tube sensor is insulated so as to respond only to the change in temperature in the first and second pockets, while the block prevents rapid bottom freezing of the cubes being sensed. The block is retained in a shiftable manner with respect to the tray to provide substantially uniform stiffness for all the tray pockets whereby twisting of the tray allows flexing of the sensing pockets to insure the release of the ice pieces formed therein.
