A refrigerator and a control method. The method includes: in response to one or more doors corresponding to one or more storage compartments of a refrigerator being all detected to be closed, obtaining a first of information; determining, by comparing the first set of information with a second set of information, one or more target tags placed in a first storage compartment of the one or more storage compartments, and determining one or more target placement times corresponding to the one or more target tags according to a current time, wherein the second set of information is an information set generated according to identity information of each RFID tag in the one or more storage compartments obtained in response to that the doors are detected to be closed last time immediately before this closing of the doors.

A cooling unit has a first door hinged to the cooling unit away from the second door and has a second door hinged to the cooling unit away from the first door, each door rotatably opening way from one another to access the chamber.

The first side of the first door faces the second side of the second door when the first door and the second door are in closed configuration to close the chamber. The first side of the first door has a first wall and a second wall forming a flat-surface-channel bottom between the first wall and the second wall. To fit between the first wall and the second wall, the second side of the second door has a gasket having an elastic surface. The elastic surface directly engages the flat-surface-channel bottom between the first wall and the second wall.

A refrigerator includes an inner case, an outer case, and an insulating material. The refrigerator includes a first door, a second door where the second door is to open and close at least another portion of a storage compartment, a rotating bar rotatable with respect to the first door or the second door so that the rotating bar covers a gap between the first door and the second door while the first door and the second door are closed; and a rotation guide coupleable to the inner case to guide the rotating bar while the rotating bar is being rotated according to opening and closing of the first door or the second door. The inner case is formed to cover a front member of the rotation guide so that the front member of the rotation guide is unexposed to a front side of the inner case.

A refrigerator includes an insulated cabinet structure and a cooling system. A door assembly includes a perimeter structure that is movably mounted to the insulated cabinet structure and an outer door that is movably mounted to the perimeter structure whereby the outer door can be moved between open and closed positions relative to the perimeter structure when the perimeter structure is in its closed position The outer door may comprise a vacuum insulated structure including porous core material disposed in a cavity of the outer door.
