Patent number: 11536508Abstract: A refrigerator includes a storage compartment and a mullion assembly pivotally coupled to one of a first door and a second door. The mullion assembly includes a cavity with an insulating member disposed therein. One or more sensor assemblies are coupled to the mullion assembly and configured to collect data sufficient to calculate a dew point temperature of the mullion assembly and an actual temperature of the mullion assembly. A heating element is coupled to the mullion assembly and is selectively activated by a controller based on information provided from the one or more sensor assemblies. The heating element is powered using a modulated power level that is inversely proportionate to the difference in temperature between the mullion assembly and the calculated dew point.Type: GrantFiled: December 10, 2020Date of Patent: December 27, 2022Assignee: Whirlpool CorporationInventors: Amit A. Avhale, Kapil Ayyawar, Rishikesh Vinayak Kulkarni, E C. Pickles, Yan Zhang

Patent number: 11320188Abstract: A refrigerator includes an outer wrapper, a fresh food compartment defined by a liner within the wrapper and separated from an interior of the outer wrapper at least along a first side wall of the fresh food compartment to define a void, and a door at least partially enclosing an opening to the fresh food compartment when in a closed position. A door compartment is positioned along the door. The refrigerator further includes an evaporator compartment positioned at least partially within the fresh food compartment and a duct in fluid communication with the evaporator compartment at a first end thereof and in communication with the door compartment a second end thereof. The duct has a first portion that extends laterally from the first end along a portion of the evaporator compartment and a second portion extending through the void along the first side wall of the fresh food compartment.Type: GrantFiled: December 20, 2018Date of Patent: May 3, 2022Assignee: Whirlpool CorporationInventors: Amit A. Avhale, Taylor Clark, Benjamin G. Jimenez, E. Calvin Pickles, Richard Spletzer, David Walter, Yan Zhang

Patent number: 10823479Abstract: A refrigerating appliance includes a refrigerant line having a compressor and a condenser. A thermal exchange media is delivered from the condenser and through the refrigerant line to at least a freezer evaporator of a plurality of evaporators, wherein the thermal exchange media leaving the freezer evaporator defines spent media that is returned to the compressor. A multi-directional outlet valve selectively delivers the thermal exchange media to the freezer evaporator, wherein the multi-directional outlet valve also selectively delivers the thermal exchange media to at least one secondary evaporator of the plurality of evaporators to define a partially-spent media that is delivered to the freezer evaporator.Type: GrantFiled: November 15, 2019Date of Patent: November 3, 2020Assignee: Whirlpool CorporationInventors: Amit A.

Patent number: 10502478Abstract: A refrigerator includes a cabinet defining a refrigerated compartment and a machine compartment. A compressor is disposed within the machine compartment and is adapted to compress a refrigerant within a refrigerant line. A micro-channel condenser is positioned in communication with the compressor and adapted to selectively reject heat from the refrigerant into the machine compartment. A condenser fan is positioned within the machine compartment between the condenser and compressor. The fan is adapted to draw heated air through the condenser and also draw fresh air from an area adjacent the machine compartment and beneath the refrigerated compartment. The heated air and fresh air combine to define mixed air that is directed toward the compressor for cooling the compressor.Type: GrantFiled: December 20, 2016Date of Patent: December 10, 2019Assignee: Whirlpool CorporationInventors: Amit A. Avhale, Bruno Boehringer, Darci Cavali, E. C. Pickles, Vijaykumar Sathyamurthi, Lihan Xu, Yan Zhang
