Referring to fig. 1 to 7, a preferred embodiment of the present invention provides an air duct assembly including an air duct main body 10 having an air duct 11 formed therein, and an air volume adjusting device 20 provided on the air duct main body 10. In this embodiment, the air volume adjusting device 20 can quantitatively adjust the air volume passing through the air duct 11, and has a simple structure and a simple operation.
Specifically, as shown in fig. 1, the air volume adjusting device 20 includes a first wind shielding member 21 and a second wind shielding member 23 rotatably disposed in the air duct 11 and engaged with each other. In this embodiment, the first wind shielding member 21 and the second wind shielding member 23 are both disposed along the cross section of the wind path 11, so that with the rotation of the first wind shielding member 21 or the second wind shielding member 23, the areas of the first wind shielding member 21 and the second wind shielding member 23 shielding the cross section of the wind path 11 are changed, and the amount of wind passing through the wind path 11 can be changed.
Of course, the air volume adjusting device 20 may be provided with two or more wind shielding members as necessary.
Further, referring to fig. 2, the first wind deflector 21 and the second wind deflector 23 have a first state in which they are in contact with each other and a second state in which they are out of contact with each other, and at least one wind deflector of the air volume adjusting device 20 is opened in the second state.
In the present embodiment, as shown in fig. 2, in the first state, the first wind shielding member 21 and the second wind shielding member 23 are all in the closed state, i.e., are parallel to the cross section of the wind tunnel 11. As shown in fig. 1, in the second state, the first wind shielding member 21 is in the open state, the second wind shielding member 23 is in the closed state, and the first wind shielding member 21 is perpendicular to the cross section of the wind tunnel 11.

In addition, in the second state, the user only needs to select to open one or two wind shielding parts to complete the air volume adjustment, and the angle between the wind shielding part and the air duct 11 does not need to be adjusted to a certain required value, so that the operation is simple, and the structure is simple.
Further, the first wind shielding member 21 and the second wind shielding member 23 are disposed in the air duct 11 oppositely, and in the first state, the wind shielding member of the air volume adjusting device 20 is closed to shield the air volume passing through the air duct 11.
In this embodiment, the first wind shielding member 21 and the second wind shielding member 23 are oppositely disposed in the wind tunnel 11, that is, the rotation axis of the first wind shielding member 21 and the rotation axis of the second wind shielding member 23 are symmetrically disposed on the left and right sides of the wind tunnel 11. Thus, when the first wind shielding member 21 and the second wind shielding member 23 are completely opened, the first wind shielding member and the second wind shielding member are attached to the left and right side walls of the air duct 11, so that interference of the wind shielding members with the air flow in the air duct 11 when the wind shielding members are completely opened is avoided, and smooth passing of the air flow in the air duct 11 is facilitated.
Of course, the first wind shielding member 21 and the second wind shielding member 23 may be disposed in a back direction or in a same direction in the air duct 11, as long as the air duct 11 is closed when the first wind shielding member 21 and the second wind shielding member 23 abut against each other.
Further, the length of the first wind shielding member 21 in the width direction of the wind tunnel 11 is equal to the length of the second wind shielding member 23 in the width direction of the wind tunnel 11.
As shown in fig. 2, in the present embodiment, the width direction of the air duct 11 refers to the left-right direction along the air duct 11, and the lengths of the first wind shielding member 21 and the second wind shielding member 23 refer to the lengths formed to extend in the direction of the central axis thereof.
Moreover, since the length of the first wind shielding member 21 is equal to the length of the second wind shielding member 23, the user can select to control one half or all of the ventilation of the air duct 11 in the second state, thereby achieving the proportional adjustment of the air duct.
Of course, the length of the first wind shielding member 21 and the length of the second wind shielding member 23 may not be equal, or the length of the first wind shielding member 21 and the length of the second wind shielding member 23 are set according to a certain proportion as required, so that the air volume required by the refrigerator in different cooling modes can be accurately satisfied.
Further, as shown in fig. 3, the air volume adjusting device 20 further includes a transmission member 25 connected to the first wind shielding member 21 and the second wind shielding member 23, respectively, and an adjusting knob 27 connected to the corresponding transmission member 25, wherein the first wind shielding member 21 and the second wind shielding member 23 rotate around the rotation axis of the corresponding adjusting knob 27, respectively.

The limit shaft 25b is rotatably disposed in the limit hole 13c, thereby limiting the deviation of the transmission member 25 in the up-down direction and the left-right direction. The outer diameter of the limiting boss 25c is larger than the inner diameter of the limiting hole 13c, so that the forward deviation of the transmission piece 25 is limited; furthermore, since the adjusting knob 27 is fixedly connected to one end of the transmission member 25, the adjusting knob 27 abuts against the cover panel 13a and cannot be shifted backward, so that the entire transmission member 25 cannot be shifted backward.
Further, as shown in fig. 6, the transmission member 25 further has a mounting hole 25d formed at an end of the limiting shaft 25b away from the rotating shaft 25a, and the first wind shielding member 21 and the second wind shielding member 23 are inserted into the corresponding mounting hole 25 d.
In this embodiment, it can be known through the foregoing that, because the driving medium 25 can't produce the skew of other directions except at wind channel main part 10 internal rotation, and first piece 21 and the second piece 23 that keeps out the wind all adopt the mode of pegging graft to connect in driving medium 25, therefore when the piece is kept out the wind in the later stage change, can directly be with keeping out the wind the piece plug in driving medium 25, made things convenient for the maintenance and changed the piece that keeps out the wind.
Specifically, each of the first wind shielding member 21 and the second wind shielding member 23 has a drive shaft 21a connected to the mounting hole 25d, and a wind shielding member 21b extending in a radial direction of the drive shaft 21a, and a central axis of the drive shaft 21a is collinear with a central axis of the mounting hole 25d and perpendicular to an axis of the rotation shaft 25 a.
In this embodiment, since the central axis of the driving shaft 21a is collinear with the central axis of the mounting hole 25d and perpendicular to the axis of the rotating shaft 25a, the thickness of the air duct main body 10 in the front-rear direction is saved.
Of course, the center axis of the mounting hole 25d may be parallel to the axis of the rotating shaft 25 a.
Further, referring to fig. 7, the air duct main body 10 further includes a heat insulating member 15 connected to the air duct cover 13, the air duct 11 is formed on the heat insulating member 15, a stroke boss 15a is provided in the air duct 11 on the heat insulating member 15, and in the first state, both the first wind shielding member 21 and the second wind shielding member 23 abut against the stroke boss 15 a.
In this embodiment, the arrangement of the stroke boss 15a can avoid the first wind shielding member 21 and the second wind shielding member 23 from being abutted by excessive rotation when the user operates the adjusting knob 27 to drive the wind shielding member to rotate. In the first state, the first wind shielding member 21 and the second wind shielding member 23 are both abutted against the stroke boss 15a, so as to avoid being blown by the airflow in the air duct 11, and the first wind shielding member 21 and the second wind shielding member 23 are separated from abutting. In the second state, when one of the first wind shielding member 21 and the second wind shielding member 23 is closed, the wind cannot be blown by the airflow in the air duct 11, and the accuracy of the air volume adjustment is affected.
