Abstract
A refrigerator includes a refrigerator cabinet having at least one door, an ice dispenser operatively connected to one of the at least one door having an opening for dispensing ice, an ice storage receptacle for storing ice disposed within the refrigerator cabinet, an ice crusher, an ice transfer mechanism for moving ice from the ice storage receptacle to the ice crusher, an ice chute for conveying ice from the ice crusher to the ice dispenser, and an intrusion barrier positioned within the ice chute to assist in preventing objects entering the ice chute through the ice dispenser from reaching the ice crusher without stopping ice flow through the ice chute. The ice dispenser may include a first switch and a second switch, the first switch being spaced apart from the second switch, and the ice dispenser adapted to require simultaneous activation of the first switch and the second switch to dispense ice. The ice dispenser may also include one or more sensors in the ice chute to detect objects moving toward the ice crusher.
