Abstract (en)

[origin: EP3978843A1] The present invention aims to provide a shielding device (70, 90) that occupies less volume of storage compartments, and a refrigerator(10, 100). The shielding device (70, 90) is used to properly close air passages (109) for supplying cold air in the refrigerator (10, 100). The shielding device (70, 90) comprises: a plurality of rotatable shielding walls (71,711,712,713,714) disposed surrounding a blower (47,107) from radially outside, and shielding wall driving mechanisms (60) configured to drive the rotatable shielding walls (71,711,712,713,714) to perform the opening or closing action. In addition, the shielding wall driving mechanism (60) has a drive motor (74, 89) serving as a drive source, and a power transmission mechanism such as gears (811, 812, 813, 814, 815, 816, 817) for transmitting the power of the drive motor (74, 89) to the rotatable shielding walls (71,711,712,713,714).
