And/or, the air outlet end of the air outlet duct 210 is coaxial with the rotation axis of the door body 100.
By this arrangement, the air outlet end of the air outlet duct 210 and the air inlet end of the air inlet duct 120 can be rotationally connected around the rotation axis of the door body 100, or the surface of the outlet 310 on the air outlet end of the air outlet duct 210 and the surface of the inlet on the air inlet end of the air inlet duct 120 can always contact and rotate relatively. And further, the outlet of the air outlet duct 210 is always communicated with the inlet of the air inlet duct 120.
Therefore, the refrigerator according to the embodiment of the invention can enable the air outlet duct 210 and the air inlet duct 120 to form a closed air path. In the opening and closing processes of the door body 100, the air inlet duct 120 does not influence the stability of the air path in the process of rotating relative to the air outlet duct 210, namely, the stability of the air path can be ensured, the sealing property of the air path is greatly improved, and the air flow can be prevented from overflowing, so that the problem that the air path of the storage space of the refrigerator door body is invalid due to the deformation of the door body 100 and the like can be solved, and the effect of adding the storage space capable of being used for a long time for the refrigerator is achieved.

The outlet 310 on the air outlet end of the air outlet duct 210 and the inlet on the air inlet end of the air inlet duct 120 are coaxial with the rotation axis of the door body 100, so as to ensure that the opening and closing of the door body 100 are not affected. Meanwhile, the inlet on the air inlet end of the multiple air inlet channels 120 is connected with the outlet 310 on the air outlet end of the air outlet channel 210, so as to meet the requirements of refrigerators with different models and different sizes.
Also for example, in some embodiments of the present invention, the air inlet end of the air inlet duct 120 is coaxial with the rotational axis of the door body, and the air inlet end of the air inlet duct 120 is inserted into the air outlet duct 210 such that the air outlet end of the air outlet duct 210 is rotatably connected with the air inlet end of the air inlet duct 120 about the rotational axis of the door body 100. And the inlet on the air inlet end of the air inlet duct 120 is located in the air outlet end of the air outlet duct 210 and is communicated with the air outlet duct 210, so that the air flow in the air outlet duct 210 enters the air inlet duct 120 through the inlet on the air inlet end of the air inlet duct 120. For another example, in some embodiments of the present invention, the air outlet end of the air outlet duct 210 is coaxial with the rotation axis of the door body 100, and the air outlet end of the air outlet duct 210 is inserted into the air inlet duct 120, so that the air outlet end of the air outlet duct 210 and the air inlet end of the air inlet duct 120 are rotatably connected around the rotation axis of the door body 100. And the outlet 310 on the air outlet end of the air outlet duct 210 is located in the air inlet end of the air inlet duct 120 and is communicated with the air inlet duct 120, so that the air flow in the air outlet duct 210 enters the air inlet duct 120 through the outlet 310 on the air outlet end of the air outlet duct 210.
In some embodiments of the present invention, as shown in fig. 6, the air outlet duct 210 includes an air supply section 211 extending in a horizontal direction. Further, the air outlet duct 210 further includes an air outlet section 212, the air outlet section 212 is horizontally arranged, the air outlet section 212 is connected to an air outlet end of the air supply section 211, a vertically arranged connecting pipe 330 is arranged on the air outlet section 212, an outlet of the connecting pipe 330 is an outlet 310 on the air outlet end of the air outlet duct 210, and an inlet of the air supply section 211 is an inlet of the air outlet duct 210.
Preferably, the upper end opening of the connection pipe 330 is an outlet 310 on the air outlet end of the air outlet duct 210, and the air inlet duct 120 is disposed on the upper side of the air outlet duct 210. The lower surface slope setting of air supply section 211 is used for the water of the air-out end of air supply section 211 to the air inlet end drainage of air supply section 211, and the lower surface of air supply section 211 is greater than or equal to 4 with the contained angle of horizontal plane.
