Optionally, in order to make the rotation of the wind outlet baffle 21 easier, so as to control the rotation angle of the wind outlet baffle 21 more accurately, the first rotating shaft assembly 22 includes a first mounting shaft 221 and a stop ball 222, the stop balls 222 are disposed at two ends of the first mounting shaft 221, the wind outlet baffle 21 is disposed on the first mounting shaft 221, the inner wall of the refrigerator housing 10 is provided with a mounting space 111, the stop ball 222 is movably disposed in the mounting space 111, and a gap is formed between the stop ball 222 and the inner wall of the mounting space 111.
As shown in fig. 4, an installation space 111 is provided on an inner wall of the refrigerator, and in the present embodiment, the installation space 111 is a spherical space. Of course, in other embodiments, the installation space 111 may be a space of other shapes, for example, a cube, etc. The stopping ball 222 is disposed in the installation space 111, so that when the air outlet baffle 21 is pushed by the cooling air, the air outlet baffle 21 rotates due to the cooperation of the stopping ball 222 and the spherical surface of the installation space 111.
In a normal state, the air outlet baffle 21 is in a vertical state and covers at least a part of the air outlet 12.
