Method for forming ice cubes in an ice making device

摘要

A refrigerator includes an ice making device for producing ice cubes. The ice making device includes a mold body having a plurality of ice forming cavities adapted to hold fluid. In an ice making cycle, air is evacuated from the cavities by a vacuum system, thereby depressurizing the cavities. Then, liquid is delivered to the depressurized cavities by a liquid delivery system, whereby an initial portion of the liquid bubbles up within the respective cavities. Once ice cubes have been formed within the cavities, the cavities are heated by a heat transfer system, thereby partially melting the ice cubes and aiding in the expulsion of ice cubes from the cavities.

主权项

1. A method for forming ice cubes in an ice making device including a mold body having at least one ice forming cavity, 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 depressurized 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.
