Abstract (en)
A refrigerator (10) capable of reducing operation noises generated by opening and closing operations of a fan cover. A shielding device (60) of the refrigerator (10) comprises the fan cover (61) covering a blower fan (50) from the outer side of a cooling chamber (23), a drive shaft (62) driving the fan cover (61) to open or close, and an electric motor (93) rotating the drive shaft (62). A control device (70) performs a closing operation for closing an air passage by rotating the drive shaft (62) in one direction to cause the fan cover (61) to approach the fan (50); and the control device performs an opening operation for opening the air passage by rotating the drive shaft (62) in another direction to cause the fan cover (61) to move away from the blower fan (50). Moreover, the control device (70) performs, during a termination period of the closing operation or opening operation, a silence operation to reduce operation noises caused by the operation of the electric motor (93).
