Thus, a gap between the damper 120 and the third sidewall of the refrigerator duct 200 can be further prevented, and air leakage can be prevented.
Further, in some embodiments of the present invention, the wind shielding member 121 having the largest extension length abuts between the third sidewall and the fourth sidewall of the refrigerator duct 200. Thus, the damper 120 can be kept in a vertical state all the time while rotating, so that the wind shielding member 121 can effectively block cold wind flowing from the freezing chamber to the refrigerating chamber.

In some embodiments of the present invention, as shown in fig. 9 and 10, the air volume adjusting structure further includes: a first limiting member 130 and a second limiting member 140 respectively disposed between the rotary member 110 and the damper 120; the first limiting member 130 is used to limit the rotating member 110 in the circumferential direction, and the second limiting member 140 is used to limit the rotating member 110 in the extending direction of the rotation axis. The first limiting member 130 can ensure that the rotating member 110 can drive the damper 120 to rotate together while rotating; the second limiting member 140 can ensure that the rotating member 110 is not separated from the damper 120 during the rotation process, so as to prevent the rotating member 110 from falling off from the refrigerator air duct 200.
Alternatively, the first limiting member 130 may be integrally formed with the rotating member 110.
In some embodiments of the present invention, as shown in fig. 2, the damper 120 has a fixing hole 120a for the first limiting member 130 to pass through; the first limiting member 130 includes: the first cambered surface 131, the first plane 132, the second cambered surface 133 and the second plane 134 are connected end to end in sequence (see fig. 10).

Further, as shown in fig. 9, a plurality of chucking through grooves 140a are provided on the wall of the chucking hole at regular intervals in the circumferential direction. The plurality of clamping through grooves 140a can increase the deformation capability of the clamping holes, so that the second limiting member 140 can effectively fix the first limiting member 130 in the extending direction of the rotation axis, and further can effectively limit the rotating member 110.

Alternatively, the number of the chucking through grooves 140a may be set to 10.
Alternatively, as shown in fig. 9, the groove width of each chucking through groove 140a gradually increases from the notch to the groove bottom. Thus, the clamping hole is more easily deformed.
In some embodiments of the present invention, the air volume adjusting structure further comprises: and a third limiting member arranged between the refrigerator air duct 200 and the damper 120, wherein the third limiting member is used for limiting the rotation angle of the damper 120. Thus, when the user rotates the rotating member 110 until the air door 120 rotates to contact with the third limiting member, the third limiting member prevents the air door 120 from continuing to rotate, and at this time, the user can determine the temperature gear corresponding to the refrigerating chamber of the refrigerator, and can accurately adjust the temperature of the refrigerating chamber of the refrigerator.
Alternatively, the range of angles by which the damper 120 can be rotated is-60 ° - +60 °, i.e., the maximum angle by which the damper 120 can be rotated in the forward direction (e.g., clockwise) is 60 °, and the maximum angle by which the damper 120 can be rotated in the reverse direction (e.g., counterclockwise) is also 60 °. As shown in fig. 4, when the damper 120 is rotated to +60 °, the temperature shift of the refrigerating compartment is the first shift (i.e., the high temperature shift); as shown in fig. 6, when the damper 120 is rotated to 0 °, the temperature shift of the refrigerating compartment is the second shift (i.e., the middle shift); as shown in fig. 8, when the damper 120 is rotated to-60 °, the temperature shift of the refrigerating compartment is the third shift (i.e., the low temperature shift).

It is understood that the bent angle of the check hole 120b is the same as the rotatable angle range of the damper 120, for example, the bent angle of the check hole 120b is set to 120 °.
Optionally, the limiting protrusion 150 is disposed on a third sidewall of the refrigerator duct 200.
Optionally, the limiting protrusion 150 is a strip-shaped protrusion extending along the circumferential direction. It is understood that the width of the bar-shaped protrusion is smaller than the width of the stopper hole 120 b.
In some embodiments of the present invention, as shown in fig. 1 and 10, a handle 140 is disposed on the second end of the rotating member 110, and the handles 111 are distributed along the radial direction of the rotating member 110. The user can hold the handle 111 to rotate the rotating member 110, so that the temperature of the refrigerating chamber can be quickly adjusted, and the user experience can be improved.
Alternatively, the handle 111 may be a straight structure, and may be integrally formed with the rotary member 110.
In some embodiments of the present invention, as shown in FIG. 1, the rotary member 110 is a tubular structure with a first end open and a second end closed, and the outer diameter of the rotary member 110 is smaller than the diameter of the damper 120. In this way, the damper 120 can be prevented from being pulled out of the refrigerator duct 200.
On the other hand, as shown in fig. 4 to 8, another embodiment of the present invention further provides a refrigerator, which includes any one of the air volume adjusting structures described above, and the air volume adjusting structure is used for adjusting the air volume in the refrigerator air duct 200.
As described above, the rotating member 110 of the air volume adjusting structure can drive the air door 120 to vertically rotate in the refrigerator air duct 200 by rotating, until the wind shielding member 121, which has a corresponding extension length, on the air door 120 is exposed in the refrigerator air duct 200 to block a part of cold wind flowing from the freezing chamber to the refrigerating chamber, so as to adjust the air volume flowing from the freezing chamber to the refrigerating chamber, thereby adjusting the temperature of the refrigerating chamber. Therefore, the air volume adjusting structure does not need to set the air door 120 as an electric door or install a temperature sensor, so that the temperature of the refrigerating chamber of the refrigerator can be adjusted, the cost of the refrigerator can be reduced, and the refrigerator can be assembled and disassembled conveniently.
As shown in fig. 3, 5 and 7, in some embodiments of the present invention, a portion of the curved surface of the damper 120 of the air volume adjusting structure, which is distributed around the rotation axis thereof, is attached to the first side wall 210 and/or the second side wall 220, which are distributed oppositely, in the refrigerator duct 200. It should be noted that the first side wall 210, the third side wall, the second side wall 220 and the fourth side wall of the refrigerator air duct 200 are sequentially connected end to end, wherein a gap between the wind shielding member 121 and the fourth side wall of the refrigerator air duct 200 can be regarded as an air outlet forming a freezing chamber. Thus, a gap between the damper 120 and the third sidewall of the refrigerator duct 200 can be prevented, and air leakage from the damper 120 can be prevented.
Further, in some embodiments of the present invention, as shown in fig. 3, 5 and 7, the first sidewall 210 of the refrigerator duct 200 is provided in a curved structure that matches the curved surface of the damper 120; the second sidewall 220 of the refrigerator duct 200 is a planar structure. Thus, the first side wall 210 of the refrigerator air duct 200 is arranged to be a curved surface structure, so that air leakage between the first side wall 210 of the refrigerator air duct 200 and the air door 120 can be avoided; the second side wall 220 of the refrigerator air duct 200 is a plane structure, so that the air in the freezing chamber can smoothly flow into the refrigerating chamber through the damper 200.
