Refrigerator air filter assembly

A refrigerator includes a liner having an opening defining an inner perimeter therein, a frame coupled with the liner around the inner perimeter and recessed from the opening, and a cover. The cover is coupled with the frame and has a major surface positioned generally flush with a portion the liner surrounding the opening. The cover defines an outer perimeter spaced apart from the inner perimeter of the opening with a portion of the frame at least partially enclosing a channel extending between the outer perimeter of the cover and the inner perimeter of the opening. The assembly further includes at least one light source directed into the channel and illuminating a portion of the frame and an air filter disposed at least partially within the cover positioned behind the major surface.

Apparatus, method, and system for filtering air to and from a refrigerated compartment of a refrigeration appliance

An apparatus, method, or system for filtered air in an interior compartment of a refrigerator. An opening in a wall of the interior liner of the refrigerator defines a channel framing a removable filter cover that tends to be at or near flush with that wall. The filter is positioned behind the cover. The space between the wall opening and the cover functions to provide both air intake into the filter and access lighting around the filter cover.

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.

Method for forming ice cubes in an ice making device

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.
