Preferably, described refrigerator wind guiding mechanism also includes shell, air guide member and actuator and is all placed in shell, has part to stretch out from the side of shell in air guide member rotation process。

Preferably, described air guide member is cam, and described cam is axisymmetric shape, divides with the axis of symmetry of cam, and the circular sliding slopes that every half cam face adopts multistage radius different forms。

Preferably, every half cam face to the minimum range of center of rotation less than the distance of described center of rotation to side, every half cam face to the ultimate range of center of rotation more than the distance of described center of rotation to side。

Preferably, described shell includes housing and upper cover, and side is a sidewall of upper cover, and housing and upper cover are mutually clamped。

Preferably, described housing is provided with boss, and boss is equiped with the screw for described refrigerator wind guiding mechanism is installed on damper positions place。

Preferably, described air door contacts with air guide member by conducting oneself with dignity。

Preferably, described air guide member and actuator are located at the medium position place of far-end。

After adopting technique scheme, this utility model has the positive effect that:

(1) the refrigerator wind guiding mechanism in this utility model, controlling, by air guide member, the size that air door is opened, air guide member is rotationally asymmetric cam, by the rotation of cam, the control to air door can be realized, can very simply realize the purpose of many gears regulation and control air quantity；

(2) the refrigerator wind guiding mechanism in this utility model, is located at the far-end of air door by air guide member and actuator, reduces the torque requirement to actuator, and air door opening department can close tight；

(3) air guide member in this utility model is axisymmetric shape, air guide member by different from the motor mode of connection, can reality air guide member rotating, adapt to different types。

Detailed description of the invention

Below in conjunction with the drawings and specific embodiments, this utility model is described in further detail。

As shown in figures 1-8, for refrigerator wind guiding mechanism of the present utility model, described refrigerator wind guiding mechanism includes air guide member 1, actuator 2, shell 3, air door 4 and rotates axle 5, rotate axle 5 and be located at one end of air door 4, being easy to the keying of air door 4, air door 4 arranges the one end rotating axle 5 and is set to near-end 41, on air door 4, the one end away from rotation axle 5 is far-end 42, shell 3 is installed on the medium position place of the far-end 42 of air door, air guide member 1 and actuator 2 and is all placed in shell 3。

Air guide member 1 is connected with actuator 2 by a rotation axle, and actuator 2 is supplied to the power that air guide member 1 rotates。Shell 3 includes the housing 32 and the upper cover 33 that are mutually clamped, and air guide member 1 and actuator 2 are placed in the coating space of housing 32 and upper cover 33 formation。

Upper cover 33 there is one side be defined as side 31。The both sides of housing 32 are provided with two boss 34, and boss 34 is equiped with screw, and described screw for being installed on air door 4 position by shell 3。Boss 34 is the platform stretching out housing 32, it is simple to the installation of screw is placed。

Wind guiding mechanism 1 is cam, described cam is axisymmetric shape, divide with the axis of symmetry of described cam, the circular sliding slopes that every half cam face adopts multistage radius different forms, namely every half cam face is all different to the distance at the center rotating axle of cam, concrete is, every half cam face to the minimum range of center of rotation less than the described center of rotation distance to side 31, every half cam face is to the ultimate range of center of rotation more than the described center of rotation distance to side 31, and namely air guide member 1 is asymmetrically shaped for rotating。Having part 31 to stretch out from the side in air guide member 1 rotation process, air door 4 contacts with air guide member 1 by conducting oneself with dignity, and the part that air guide member 1 stretches out is to control the size of air door 4 ventilation。

Refrigerator wind guiding mechanism of the present utility model, by the difference of air guide member 1 rotational angle, it is possible to reach to control the purpose of refrigerator air door 4 ventilation, it might even be possible to reach the purpose of stepless regulating refrigerator。

It will be apparent to those skilled in the art that can technical scheme as described above and design, make other various corresponding changes and deformation, and all these change and deformation all should belong within the protection domain of this utility model requirement。
