The air outlet of the different height of region I and the air outlet connection for being connected to orientation supply air duct 20.By driving shaft 32b
Block B rotation, can make different block B block different air outlets 331, the air outlet being blocked in different turned positions
331 closings, the unlatching of air outlet 331 not being blocked (turned position by controlling block B can control the degree blocked, from
And the opening degree of air outlet 331 is controlled, and then control the air output of air outlet 331), thus the cold wind entered from air inlet 31
It can be blown by the different air outlets 331 not being blocked.It, can be to the first storage of refrigerator by different air outlets 331
Tibetan area domain I and/or orientation supply air duct 20 are blown.
For the rotation for realizing shaft 32b, the air controller 30 may include rotating bracket 34, and the shell 33 is fixed on
The rotating bracket 34, the control unit are rotatably installed on the rotating bracket 34.
It, can be by various mode drive shaft 32b appropriate, for example, the air controller 30 can wrap in the present invention
The driving motor 35 for driving the control unit rotation is included, can also be protected by protective cover 351 on the outside of driving motor 35.It is excellent
Selection of land, the driving motor 35 is either-rotation motor, needed for more accurately drive shaft 32b is turned within the scope of 360 °
Operating mode.It wherein, is the accurate starting for determining 360 ° of slewing areas or final position, it is preferable that the drive shaft 32b
The stop configurations being fitted to each other are provided with in the rotating bracket 34.For example, the first correcting block can be set on shaft 32b
321, it can be set in rotating bracket 34 in the starting of required positioning or final position and 321 counter stopper of the first correcting block
Second correcting block.
Wherein, the corresponding position of each operating mode, the air controller 30 are turned to for further accurate control shaft 32b
It is configured to the outlet air state for having n kind different, the driving motor 35 is stepper motor and is set as between being with 360 °/n
Every angular turn.Illustrate the outlet air state under different working modes below with reference to Figure 15 to Figure 22.The embodiment party shown in Figure 14
In formula, air outlet 331 includes the first air outlet 331a, the second air outlet 331b and the third air outlet 331c set gradually, point
The air-supply of axial region 1, axial region 2 and axial region 3 is not corresponded to, and air controller 30 is configured to go out by first respectively
Air port 331a, the second air outlet 331b and third air outlet 331c realize operating mode of individually blowing, can pass through any two
Air outlet 331, which is realized, combines air-supply operating mode, the full air-supply operating mode that can be realized three air outlets 331 while blowing simultaneously
And it can be realized the close pattern for all closing three air outlets 331.Wherein, the first air outlet 331a and the second air outlet
331b can be used for blowing to the first storage area I, and third air outlet 331c can be used for blowing to orientation supply air duct 20.Root
According to needs, more multi-air outlet 331 also can be set, and by different location and the air outlet 331 of quantity to the first storage area
I and orientation supply air duct 20 are blown.In the illustrated embodiment, air controller 30 needs to have 8 operating modes, then can be with
Driving motor 35 is set as rotating with 45 ° for angle interval.For this purpose, there are each air outlet 331 4 operating modes to close, 4
A operating mode is opened, and 4 block B of corresponding each air outlet 331 are provided on shaft 32b, are axially offset by edge and right
The block B of neat difference air outlet 331, may be implemented above-mentioned 8 operating modes and (here, only illustrates air outlet 331 completely by block
B block and close or be not blocked completely and the operating mode opened).The realization sequence of specific operating mode can be according to need
It selects.
