Publication number: 20230175764Abstract: A storage assembly including a vacuum insulated cabinet, a refrigeration system, and a drawer. The vacuum insulated cabinet is formed by a number of insulated panels. The vacuum insulated cabinet and the refrigeration system collectively form a refrigerated compartment. The drawer is configured to move between an open position, in which an interior portion of the drawer is accessible, and a closed position, in which the drawer is disposed in the refrigerated compartment and the interior portion of the drawer is inaccessible. The refrigeration system includes a first heat exchanger, including one of a thermoelectric device or an evaporator, disposed between the drawer and a rear portion of the insulated cabinet, and a second heat exchanger, including one of a condenser or thermoelectric device, disposed in a machine compartment adjacent to the refrigerated compartment.Type: ApplicationFiled: October 4, 2022Publication date: June 8, 2023Inventors: Vishal CHAUHAN, Rahul CHHAJED, Daniel CHOW, Mansi KATKAR, Mandar KULKARNI, Deepak MANKAR, Manjunathraddi NAVALGUND

Patent number: 11293688Abstract: An insulated structure includes a wrapper that defines a first aperture. A liner defines a second aperture and is coupled to the wrapper. A negative pressure is maintained between the wrapper and the liner. A drainage assembly extends between the liner and the wrapper and is disposed within the first aperture and the second aperture. The drainage assembly includes a flexible body that has a plurality of flexures, first and second surfaces, and an opening that is defined between the first and second surfaces. The flexible body has at least one notch that is defined on the first surface that extends from a portion of the opening. A drainage tube extends through the opening that is defined by the flexible body and is operably coupled to the flexible body. The drainage tube includes at least one flange disposed within the at least one notch of the flexible body.Type: GrantFiled: September 2, 2020Date of Patent: April 5, 2022Assignee: Whirlpool CorporationInventors: Rahul Chhajed, Mansi Katkar, Mandar Gopalkrushna Kulkarni, Rafael Dutra Nunes, Sanjesh Kumar Pathak, Manoj T.

Patent number: 10648701Abstract: A refrigerator of the present invention includes a refrigeration system having a water-cooled condenser and a liquid line heat exchanger for additional cooling with the water, at a position upstream in the direction of flow of water from the cooling that occurs at the condenser. The use of water cooling at these two portions of the refrigeration system improves the energy efficiency of the refrigerator, while also significantly improving temperature responsiveness (e.g., reducing an amount of time necessary to “pull down” the temperature of a cooled space in the refrigerator to a desired set point temperature). The refrigerator may include one or a plurality of refrigeration stages, in various embodiments, and an additional sub-cooling heat exchanger may be provided in the refrigeration system downstream from the liquid line heat exchanger when the refrigerator includes multiple cascaded circuits.Type: GrantFiled: February 6, 2018Date of Patent: May 12, 2020Assignee: Thermo Fisher Scientific (Asheville) LLCInventor: Rahul Chhajed
