Refrigerator ice door mechanism

摘要

A refrigerator ice door mechanism having improved structure for controlling the outlet opening of a delivery chute provided for delivering ice pieces from an ice maker within the refrigerator to an access space in the front of the door. The closure is positively opened by operation of the ice dispenser actuating structure and is biased to a closed position substantially immediately after release of the actuating structure for terminating operation of the ice piece delivery structure, while permitting any remaining ice pieces moving through the ice delivery chute to move the closure away from the opening in passing to the access space. A time delay device is provided for applying a sealing force to the closure to positively close the opening a predetermined period of time subsequent to the release of the actuator and termination of the ice piece delivery.
