In the prior art, side-by-side refrigerators are generally provided with a single refrigeration system to control temperatures of a refrigerating compartment and a freezing compartment, respectively. The refrigerating chamber and the freezing chamber are partitioned by a partition plate. The baffle is provided with a return air channel and an air supply channel. The single refrigeration system is arranged in the refrigerating chamber. When the refrigerating chamber needs cold, the fan of the single refrigerating system is started, and air flows and circulates in the refrigerating chamber and the freezing chamber through the air supply channel and the air return channel. However, when the refrigerator compartment does not require refrigeration, cool air within the freezer compartment permeates into the refrigerator compartment from the return air passage, causing supercooling of the region of the refrigerator compartment adjacent the return air passage, resulting in freezing of the refrigerated items.

To this end, referring to fig. 1, 2 and 7, an embodiment of the present utility model provides a refrigerator including:

a case 100;

the first air door 300 is rotatably connected with the partition board 200, and is arranged corresponding to the return air channel 210;

a first driving member 500, the first driving member 500 being mounted on the partition 200 and connected to the first damper 300, and configured to drive the first damper 300 to rotate between a first position closing the return air duct 210 and a second position opening the return air duct 210.

In the technical solution of the embodiment of the present utility model, the first damper 300 and the first driving member 500 for driving the first damper 300 are disposed at the return air duct 210 of the partition 200. The first driving piece 500 drives the first damper 300 to open or close the return air duct 210. When the refrigerating chamber 120 does not need to be refrigerated, the first driving member 500 drives the first air door 300 to close the return air channel 210, so that cold air in the freezing chamber 110 cannot permeate into the refrigerating chamber 120 through the return air channel 210, and the technical problem that the area of the refrigerating chamber 120 close to the return air channel 210 is supercooled, which results in freezing of refrigerated articles is solved.
