Abstract (en)

[origin: EP3978842A1] The present invention aims to provide a shielding decvice (70) that occupies less volume of storage compartments, and a refrigerator (10, 100). The shielding device (70) is used to properly close air passages (109) for supplying cold air in the refrigerator (10, 100). The shielding device (70) comprises: a plurality of rotatable shielding walls (71, 711, 712, 713, 714, 715) disposed surrounding a blower (47) from radially outside, and shielding wall driving mechanisms (60, 601, 602) configured to drive the rotatable shielding walls (71, 711, 712, 713, 714, 715) to perform the opening or closing action. With a plurality of shielding wall driving mechanisms (60, 601, 602) being provided, the shielding device (70) improves a degree of freedom of the rotatable shielding walls (71, 711, 712, 713, 714, 715) in performing the opening or closing action.
