Referring to fig. 5 to 7, a first state, a second state and a third state of the cold air flow direction of the cylindrical refrigerator 100 when the movable air guide 6 is located at different positions are respectively illustrated. When the movable air guide 6 is located at the first position shown in fig. 5, the circumferential wind-blocking portion 63 of the movable air guide 6 covers the air supply opening of the main air duct 1 to the second air duct 5, and cold air cannot pass through the second air duct 5 but can only completely enter the first air duct 3 through the gap between the circumferential wind-blocking portion 63 and the axial wind-blocking portion 61, and finally air is discharged from the air outlet 35 of the bottom plate 33 of the first air duct 3 under the uniform flow dividing action of the air guide 4, and the cold air is blown from the top of the first compartment 105 to the bottom thereof. In the first state, the cool air flows into the first air duct 3 entirely to cope with a situation such as a sudden temperature increase caused by the first compartment 105 being opened for a long time.

As shown in fig. 9, the two disks 65, 65a are engaged in a sleeved manner, wherein the inner disk 65a and the outer disk 65 are sleeved in a clearance fit manner to rotate relatively. In this embodiment, the outer disc 65 is fixed relatively, and the inner disc 65a rotates along the inner wall of the outer disc 65, during the rotation, the ventilation holes 651 of the inner disc 65a on the first wind shielding surface and the second wind shielding surface are overlapped or staggered with the corresponding ventilation holes on the outer disc 65, so as to realize the above three matching states. Of course, in other embodiments, the inner disk 65a may be configured to be fixed differently, while the outer disk 65 rotates along the outer circumference of the inner disk 65 a. The two disks 65, 65a may be axially positioned by a fixed shaft (not shown) axially disposed within the main duct 1, or other means to enable axial positioning.
