FAST ICE MAKING DEVICE

摘要

A refrigerator includes a fast ice making device for quickly producing ice cubes. The fast ice making device includes a mold body having a plurality of ice forming cavities adapted to hold fluid. In an ice making cycle, a vacuum system evacuates air from the cavities, thereby depressurizing the cavities. Then, a liquid delivery system delivers liquid to the depressurized cavities, whereby an initial portion of the liquid bubbles up within the respective cavities. Overall, a cooler fluid is established at the beginning of an ice making cycle, thus accelerating the rate at which ice cubes are formed within the fast ice making device. Once ice cubes have been formed within the cavities, a heat transfer system is utilized to heat the cavities, thereby slightly melting the ice cubes and aiding in the expulsion of ice cubes from the cavities.

主权项

1. A method for quickly forming ice cubes in a fast ice making device including a mold body having at least one ice forming cavity therein, said method comprising:
activating a vacuum system in communication with the at least one ice forming cavity to evacuate air from the at least one ice forming cavity to establish a depressurize at least one ice forming cavity; activating a liquid delivery system in communication with the depressurized at least one ice forming cavity to deliver a liquid to the depressurized at least one ice forming cavity; causing at least an initial portion of the liquid delivered to the depressurized at least one ice forming cavity to boil; and freezing the liquid in the depressurized at least one ice forming cavity to form ice.
