If ring-shaped article, rotary part 132 can be rotatably mounted between wind turbine and air outlet 111.
When the wind-force of the wind of wind turbine blowout is zero, rotary part 132 is still in initially under the gravity of its own
Position, i.e. the rotation angle of rotary part 132 is zero, can carry out dynamic adaptation to the air return system air quantity of refrigerator at this time；Work as wind
When the wind-force of the wind of machine blowout is more than zero, under the action of the different wind-force that rotary part 132 is blown out in its own gravity and wind turbine
Rotatable different angle at this time can allocate the air quantity of the supply air duct of refrigerator；Continue to increase when wind turbine blows out wind-force,
So that on 1323 wall of sleeve during the either end contact card-bit part 1313 of notch 1324, the rotation angle of rotary part 132 is maximum,
Rotary part 132 turns to extreme position at this time.In this way, the wind that rotating mechanism 13 is blown out according to its own gravity and wind turbine
Wind-force size and with different rotation angles to dynamically adjust the air quantity that wind turbine is sent to air outlet 111, more reasonable employment
With allocating cold wind.
Preferably, the quantity of rotating mechanism 13 can be set according to actual needs, and the size of notch 1324 is also according to reality
Need what is set, if it is desired to more broadly adjust the air quantity that wind turbine is sent to air outlet 111, the size of notch 1324 can be set
That puts is larger, conversely, the size of notch 1324 can then set it is smaller.
It is obvious to a person skilled in the art that the invention is not restricted to the details of above-mentioned exemplary embodiment, Er Qie
In the case of without departing substantially from spirit or essential attributes of the invention, the present invention can be realized in other specific forms.Therefore, no matter
From the point of view of which point, the present embodiments are to be considered as illustrative and not restrictive, and the scope of the present invention is by appended power
Profit requirement rather than above description limit, it is intended that all by what is fallen within the meaning and scope of the equivalent requirements of the claims
Variation is included within the present invention.Any reference numeral in claim should not be considered as to the involved claim of limitation.
Moreover, it will be appreciated that although this specification is described in terms of embodiments, but not each embodiment is only wrapped
Containing an independent technical solution, this description of the specification is merely for the sake of clarity, and those skilled in the art should
Using specification as an entirety, the technical solutions in each embodiment can also be properly combined, forms those skilled in the art
It is appreciated that other embodiment.
