In this way, in the air-cooled refrigerator of the present embodiment, the air volume distribution mechanism is provided, the first wind deflector 41 is provided at the first air supply port 131, the second wind deflector 42 is provided at the second air supply port 132, and the air volume of the air in the air supply chamber entering the first compartment and the second compartment is controlled by the first wind deflector 41 and the second wind deflector 42, so that the air volume distribution is realized, the air volume distribution around the blower 20 is not required, the wind resistance around the blower 20 is reduced, and the efficiency of the blower 20 is ensured.
In the present embodiment, the blower 20 is provided as a centrifugal fan, wherein the axis extends in the front-rear direction, and when it is operated, the blower 20 drives air away from the blades thereof in a direction perpendicular to the axis, that is, the blower 20 blows air around in a direction perpendicular to the axis.
The extending direction of the first air blowing port 131 and/or the second air blowing port 132 is perpendicular to the air outlet direction of the blower 20, in other words, the extending direction of the first air blowing port 131 and/or the second air blowing port 132 is parallel to the central axis of the blower 20 (extends in the front-rear direction). In this way, the efficiency of the blower 20 can be further ensured.

Further, the driving member 70 is provided as a stepping motor, which is assembled and fixed on the rear surface 12 of the front cover plate 10.
Further, the transmission assembly includes a crankshaft 60 connected to the driving member 70 and a rotation link connecting the crankshaft 60 and the wind shielding assembly. Wherein the driving member 70 drives the crankshaft 60 to rotate around a shaft axis T, and the crankshaft 60 comprises a crank arm having a radial displacement with respect to the shaft axis T; both ends of the rotating link are rotatably connected to the crank arm and the wind shielding assembly, respectively, i.e., one end (upper end in this embodiment) thereof is rotatably connected to the crank arm and the other end (lower end in this embodiment) thereof is rotatably connected to the wind shielding assembly. When the crankshaft 60 rotates around the axis T, the crankshaft arm drives the wind shielding assembly to move linearly through the rotating connecting rod.
Further, the crank arms include a first crank arm 61 and a second crank arm 62, and the rotating connecting rods include a first rotating connecting rod 31 rotatably connected to the first crank arm 61 and a second rotating connecting rod 32 rotatably connected to the second crank arm 62. When the crankshaft 60 rotates around the axial lead T, the first crank arm 61 drives the first wind deflector 41 to move linearly through the first rotating connecting rod 31, so that the first wind deflector 41 regulates the open/close state of the first air supply opening 131; meanwhile, the second crank arm 62 drives the second air blocking plate 42 to move linearly through the second rotating connecting rod 32, so that the second air blocking plate 42 regulates the open/close state of the second air blowing opening 132.
In this embodiment, the first wind deflector 41 and the second wind deflector 42 are both disposed in the air supply cavity, and the first wind deflector 41 and/or the second wind deflector 42 are disposed in a flexible material, preferably, both are disposed in a silica gel material. Thus, when the blower 20 is in operation, positive pressure is formed in the blowing cavity, so that the first wind blocking plate 41 can be tightly attached to the rear surface 12 of the front cover plate 10 when blocking the first blowing port 131, and the second wind blocking plate 42 can be tightly attached to the rear surface 12 of the front cover plate 10 when blocking the second blowing port 132, thereby preventing air leakage and ensuring stable controllability of storage temperature.
Further, the first wind deflector 41 and the second wind deflector 42 each slidingly abut against the rear surface 12 of the front cover 10.
Further, in the present embodiment, the air duct system includes a plurality of the first blowing ports 131 arranged in the vertical direction and a plurality of the second blowing ports 132 arranged in the vertical direction; accordingly, the wind shielding assembly includes a plurality of first wind shielding plates 41 corresponding to the plurality of first wind blowing ports 131 and a plurality of second wind shielding plates 42 corresponding to the plurality of second wind blowing ports 132.
The wind shielding assembly further comprises a first translational link 51 and a second translational link 52. A first connecting rod 51 is rotatably connected to the lower end of the first connecting rod 31, and a plurality of first wind deflectors 41 are fixed to the first connecting rod 51, so that when the crankshaft 60 rotates around the axis T, the first crank arm 61 drives the first connecting rod 51 to move through the first connecting rod 31, and thus the first wind deflectors 41 move synchronously; similarly, a second translational connecting rod 52 is rotatably connected to the lower end of the second rotating connecting rod 32, and a plurality of second wind blocking plates 42 are fixed to the second translational connecting rod 52, so that when the crankshaft 60 rotates around the axis T, the second crank arm 62 drives the second translational connecting rod 52 to move through the second rotating connecting rod 32, and thus the plurality of second wind blocking plates 42 move synchronously.
In this embodiment, the plurality of first wind deflectors 41 regulate and control the plurality of first air blowing openings 131 to be in the same open and close states at the same time, that is, the plurality of first air blowing openings 131 are opened, closed or partially opened at the same time; similarly, the second wind blocking plates 42 regulate the second wind blowing openings 132 to be simultaneously in the same open/close state, that is, the second wind blowing openings 132 are simultaneously opened, closed or partially opened. Of course, in an alternative embodiment, the plurality of first blowing ports 131 may be in different open/close states, and the plurality of second blowing ports 132 may be in different open/close states.
Further, in the present embodiment, the first and second translational links 51 and 52 are each provided as a U-shaped bar structure.

The wind shielding assembly is vertically and slidably arranged behind the front cover plate 10. That is, when the driving member 70 is operated, it drives the crankshaft 60 to rotate around the shaft axis T, and the crankshaft 60 drives the wind shielding assembly to slide up and down relative to the rear surface 12 of the front cover 10 through the rotating connecting rod.
