Patent number: 12281838Abstract: A refrigerator includes a cabinet, a door, and a partition. The cabinet defines an air inlet and an air outlet. The door is movably secured to the cabinet. The door is configured to transition between open and closed positions. The partition is movably secured to the door. The partition is configured to advance away from the door to transition to an operational position. The partition is configured to retract toward the door to transition to a stowed position. In response to closing the door, the partition transitions to the operational position and engages the cabinet to separate the air inlet from the air outlet. In response to opening the door, the partition transitions to the stowed position and provides clearance within a space that is defined between the door and the cabinet when the door is in the open position.Type: GrantFiled: June 7, 2023Date of Patent: April 22, 2025Assignee: Whirlpool CorporationInventors: Luiz Afranio Alves Ferreira, Marcel Bögger Lessa, Gustavo Spezzia
