As shown in fig. 9, the second burring 480 may be divided into two parts, one of which is provided on the first link 450 and the other of which is provided on the second link 460.

To sum up, the utility model provides a refrigerator compares with prior art, includes following beneficial effect at least:

firstly, the method comprises the following steps: the air door 500 is arranged in the connecting air duct 410 and sealed with the inner cavity of the air duct connecting assembly 400 through the first sealing part 600, so that cold air output from the first air duct 210 can be output to the second air duct 310 after the air door 500 is opened, cold air leakage is avoided, and cold leakage during cold air transportation is prevented.

Secondly, the method comprises the following steps: air door 500 sets up in wind channel coupling assembling 400, when air door 500 closes and the fan of freezer lasts the work, first wind channel 210 forms the high-pressure wind district to the region of air door 500, and second wind channel 310 is the low pressure wind district to the region of air door 500, make the high-pressure cold air in high-pressure wind district unable through air door 500, then leak in the gap between unable wind channel coupling assembling 400 and the cold wind entry 320 this moment, avoid high-pressure cold air to leak to the cold-storage chamber of second inner bag 300 in the gap of wind channel coupling assembling 400 and cold wind entry 320, prevent that cold-storage chamber bottom region from being in subzero temperature, eliminate the risk that article were frozen out in the refrigerator cold-storage bottom drawer, promote user's use and experience.

Thirdly, the method comprises the following steps: by arranging the second sealing member 471 and the third sealing member 481, cold air can be prevented from leaking from the installation gaps between the air duct connecting assembly 400 and the first inner container 200 and the second inner container 300, and cold leakage of the refrigerator is avoided.

The above is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and substitutions can be made without departing from the technical principle of the present invention, and these modifications and substitutions should also be regarded as the protection scope of the present invention.
