The rotating motor 321 drives the gear shaft 324 to rotate, and drives the connecting disc 340 to rotate so that the second clamping positions 342 align the clamping blocks 223. Then, the lifting motor 311 drives the connecting disc 340 to move towards the fan blade 211 through the lifting column 312, so that the second engaging positions 342 are engaged with the clamping blocks 223. At this time, the rotating structure 320 drives the gear shaft 324 and the connecting disc 340 to rotate, so as to synchronously adjust the plurality of air doors 210, thereby adjusting the size of the air outlet 131, and the air outlet 131 outputs the flow direction of the cold air.

When temperature difference changes occur in different areas of the refrigerating compartment 120 along with placement of articles or other unexpected factors in the refrigerator, the lifting motor 311 drives the connecting disc 340 to move away from the fan blade 211 so as to separate the connecting disc 340 from the clamping block 223. The rotating motor 321 drives the connecting disc 340 to rotate, so that the first clamping position 341 is aligned with the transmission structure 220 with the temperature change area. Then, the lifting motor 311 drives the connecting disc 340 to move towards the fan blade 211 so that the first clamping position 341 is clamped with the clamping block 223 in the corresponding area, and the rotating motor 321 rotates so that the connecting disc 340 can independently adjust the fan blade 211 corresponding to the air outlet 131, thereby adjusting the size of the air outlet 131 in the corresponding area and the flow direction of cold air, ensuring the temperature of each area in the refrigeration compartment 120, and improving the use experience of users.

In this application, during the use of the cylindrical refrigerator, cool air produced by the refrigerating system enters the refrigerating compartment 120 through the air outlet 131. In the refrigerating and storing process of the refrigerator, the lifting structure 310 drives the connecting disc 340 to lift so as to be separated from the transmission structure 220, and the rotating structure 320 rotates the connecting disc 340, so that the lifting structure 310 drives the connecting disc 340 to lift, and the first clamping position 341 or the second clamping position 342 on the connecting disc 340 can be respectively connected with the transmission structure 220, so as to adjust the air door 210 to open and close the air outlet 131. When the first engaging position 341 is connected with a transmission structure 220, the rotation structure 320 rotates to drive the transmission structure 220 and the damper 210 at the single air outlet 131 to move, thereby adjusting the size of the single air outlet 131. When the second clamping position 342 is connected with the plurality of driving structures 220, the connecting disc 340 can simultaneously drive the driving structures 220 and the damper 210 on the plurality of air outlets 131 to move, thereby adjusting the sizes of the plurality of air outlets 131. The cylinder refrigerator can simultaneously adjust the sizes of a plurality of air outlets 131 in the refrigeration compartment 120 through the adjusting mechanism 300, and can also adjust the sizes of single air outlets 131 in the refrigeration compartment 120, so that the temperatures of different areas in the refrigeration compartment 120 can be balanced, the local temperature difference in the refrigeration compartment 120 is prevented from being too large, the efficiency of refrigerating and freezing objects is ensured, and the user experience is improved.
