Meets the needs of refrigerator is to two-way ventilating amount.
Spiral case 10 and wind turbine 1 according to the ... of the embodiment of the present invention for refrigerator is by being arranged for accommodating centrifugal fan 20
First chamber 1011 and second chamber 1021, so as to according to refrigerator to upper air outlet 1013 air output and lower air outlet
Axial height of the centrifugal fan 20 in first chamber 1011 is arranged and in second chamber in the demand of 1023 air output
Axial height in 1021, it is possible thereby to meet the needs of refrigerator is to two-way ventilating amount.
Therefore, the spiral case 10 and wind turbine 1 according to the ... of the embodiment of the present invention for refrigerator can preferably meet refrigerator to double
To the demand of air output.
As shown in Figure 1-Figure 3, wind turbine 1 according to some embodiments of the present invention includes spiral case 10, centrifugal fan 20 and drives
Dynamic motor.
Spiral case 10 includes the first sub- spiral case 101 and the second sub- spiral case 102.First sub- spiral case 101 has first chamber 1011
And the first opening 1012 and opening up upper air outlet 1013 being connected to first chamber 1011.Second sub- spiral case 102 has
The second opening 1022 and downward opening lower air outlet 1023 for having second chamber 1021 and being connected to second chamber 1021.
Specifically, each in the first sub- spiral case 101 and the second sub- spiral case 102 has complete volute structure.
That is, setting fan can form a wind turbine in the first sub- spiral case 101, fan is set in the second sub- spiral case 102
A wind turbine can also be formed.
One in first sub- spiral case 101 and the second sub- spiral case 102 is equipped with air inlet 1014.First sub- spiral case 101 with
Second sub- spiral case 102 is connected, and first chamber 1011 is connected with second chamber 1021 by the first opening 1012 and the second opening 1022
It is logical.A part for centrifugal fan 20 is located in first chamber 1011, and the rest part of centrifugal fan 20 is located at second chamber 1021
It is interior.
That is, a part for a part for the first sub- spiral case 101 and the second sub- spiral case 102 with centrifugal fan 20
It is overlapped in axially vertical plane, the first opening 1012 is located in the part of the first sub- spiral case 101, the second opening 1022
It is located in the part of the second sub- spiral case 102.When centrifugal fan 20 rotates, blade acting of the air-flow through centrifugal fan 20
Afterwards, the diffusion intracavitary of the part inflow first chamber 1011 of air-flow is carried out pressure expanded and is flowed out from upper air outlet 1013, gas
The diffusion intracavitary that the rest part of stream flows into second chamber 1021 is carried out pressure expanded and is flowed out from lower air outlet 1023.
In one embodiment of the invention, the shape of the first opening 1012 is identical as the shape of the second opening 1022, the
The size of one opening 1012 is equal in magnitude with the second opening 1022, the side at the edge of the first opening 1012 and the second opening 1022
Along connected.It is possible thereby to keep the structure of spiral case 10 and centrifugal fan 20 more reasonable.

The diameter of second opening 1022.
The edge of first opening 1012 with second be open 1022 rim seal be connected, thus it can be prevented that air-flow from the
It reveals the junction of one sub- spiral case 101 and the second sub- spiral case 102.
In the specific example of the present invention, the first sub- spiral case 101 and the second sub- spiral case 102 are integrally formed.Thus may be used
To reduce the manufacture difficulty and manufacturing cost of spiral case 10.
The present invention some examples in, centrifugal fan 20 along the drive shaft of the driving motor length direction movably
It is located in the drive shaft, to change axial height of the centrifugal fan 20 in first chamber 1011 and second chamber 1021.
As described above, axial height phase of the air output of upper air outlet 1013 with centrifugal fan 20 in first chamber 1011
It closes, the air output of lower air outlet 1023 is related to axial height of the centrifugal fan 20 in second chamber 1021.Therefore, pass through edge
The length direction movement centrifugal fan 20 (axial position for adjusting centrifugal fan 20) of the drive shaft, so as to change centrifugation
Axial height of the fan 20 in first chamber 1011 and second chamber 1021, and then the outlet air of upper air outlet 1013 can be changed
The air output of amount and lower air outlet 1023.It is possible thereby in real time, preferably meet the needs of refrigerator is to two-way ventilating amount.
In the example of the present invention, the refrigeration compartment of refrigerator includes refrigerating chamber and the freezing positioned at the lower section of refrigerating chamber
Room, upper air outlet 1013 are connected to the refrigerating chamber, and lower air outlet 1023 is connected to the freezing chamber.
Refrigerator further comprises the refrigerated storage temperature detector of the temperature for detecting the refrigerating chamber, for detecting the freezing chamber
Temperature cryogenic temperature detector, actuator and controller.The refrigerated storage temperature detector is located in the refrigerating chamber, the freezing temperature
Degree detector is located in the freezing chamber.The actuator is connected to drive centrifugal fan 20 along the driving motor with centrifugal fan 20
Drive shaft length direction movement.In other words, which is used to adjust the axial position of centrifugal fan 20.
The controller is connected with the refrigerated storage temperature detector, the cryogenic temperature detector and the actuator, so as to the control
Device controls the actuator according to the temperature detection value of the refrigerated storage temperature detector and the temperature detection value of the cryogenic temperature detector
Driving centrifugal fan 20 is moved along the length direction of the drive shaft.
Specifically, when the temperature detection value of the refrigerated storage temperature detector is more than the set temperature value of the refrigerating chamber, it should
Controller can control actuator driving centrifugal fan 20 and be moved into first chamber 1011 along the length direction of the drive shaft,
To increase axial height of the centrifugal fan 20 in first chamber 1011.It is possible thereby to increase the upper air outlet 1013 of wind turbine 1
Air output, so that more cold wind is entered in the refrigerating chamber, to make the indoor temperature of the refrigeration rapidly decline.
When the temperature detection value of the cryogenic temperature detector is more than the set temperature value of the freezing chamber, which can be with
Control the actuator driving centrifugal fan 20 moved into second chamber 1021 along the length direction of the drive shaft, so as to increase from
Axial height of the heart fan 20 in second chamber 1021.It is possible thereby to increase the air output of the lower air outlet 1023 of wind turbine 1, make
More cold wind enter in the freezing chamber, to make the indoor temperature of the freezing rapidly decline.
When the temperature detection value of the refrigerated storage temperature detector is more than the set temperature value of the refrigerating chamber and cryogenic temperature inspection
When the temperature detection value of survey device is more than the set temperature value of the freezing chamber, preferentially freeze to the refrigerating chamber.That is, should
Controller first controls actuator driving centrifugal fan 20 and is moved into first chamber 1011 along the length direction of the drive shaft, waits for
After the indoor temperature of the refrigeration is less than set temperature, which controls the actuator and drives centrifugal fan 20 along the drive shaft again
Length direction moved into second chamber 1021.
