Air-cooled refrigerator

An air-cooled refrigerator, comprising a cabinet, wherein the cabinet is provided with a cellar compartment, at least one storage compartment, and an air duct assembly communicating the cellar compartment and the at least one storage compartment, wherein

• the air duct assembly is provided with an accommodating cavity with a rearward air inlet, and a plurality of air supply communicating holes is formed in a peripheral wall of the accommodating cavity;
• air in the cellar compartment enters the at least one storage compartment via the plurality of air supply communicating holes;
• the air-cooled refrigerator further comprises an air door shielding device;
• the air door shielding device is provided with a shielding part, and the shielding part is provided with a plurality of air baffles;
• the shielding part is rotatably disposed in the accommodating cavity, so as to have shielding positions for the plurality of air baffles to completely shield all the air supply communicating holes, thus further preventing the air in the cellar compartment from entering the at least one storage compartment via the plurality of air supply communicating holes during the defrosting of the air-cooled refrigerator;
• a bottom of a sidewall of the accommodating cavity is provided with a water guide groove inclined rearward and downward, and the air duct assembly is provided with a water outlet hole communicating a rear side of the air duct assembly with a rear end of the water guide groove, so that water in the accommodating cavity flows out of the air duct assembly via the water guide groove and the water outlet hole;
• the air door shielding device further comprises:
• a base, wherein the shielding part is further provided with a turntable portion rotatably mounted on the base;
• the plurality of air baffles extends from the turntable portion to a rear side, and is disposed at intervals in a circumferential direction of the turntable portion;
• a motor, disposed on a radial outer side of the shielding part, and mounted on the base:
• a driving gear, mounted on an output shaft of the motor;
• and
• a driven gear, mounted on the turntable portion or integrally formed with the turntable portion, and meshed with the driving gear, wherein
• the driven gear is a gear ring disposed on a side of the turntable portion facing away from the air baffles;
• the base comprises a base plate, a bottom cover, and a first position baffle extending from one side of the base plate;
• the turntable portion is mounted on a radial outer side of the first position baffle, and each of the air baffles extends out of the other side of the base plate;
• the bottom cover covers the one side of the base plate, an inner side of the bottom cover is provided with a second position baffle and a third position baffle, and the gear ring is disposed on a radial outer side of the second position baffle and a radial inner side of the third position baffle;
• the second position baffle is provided with a notch;
• the side of the turntable portion facing away from the air baffles is further provided with a bump disposed within the notch to define a rotating range of the turntable portion;
• a side of the turntable portion facing the base plate is provided with an annular rib;
• and
• a side of an edge of the base plate facing the turntable portion is an inclined surface.
