301st, the current refrigeration situation between at least two Room is determined.
It should be noted that refrigeration situation is exactly whether to need refrigeration between each room respectively.Exemplary, as shown in Figure 1
Refrigerator, if refrigerating chamber need refrigeration, no matter refrigerating chamber whether need refrigeration, then refrigeration situation now is set to the first
Refrigeration situation；If refrigerating chamber need not freeze, refrigerating chamber needs refrigeration, then refrigeration situation now is set into second of refrigeration
Situation.
It should be noted that the current refrigeration situation between each room can be determined according at least to the on off state of each air door,
The current refrigeration situation between each room can also be determined according to the actual temperature between each room and advance target temperature, can be with root
The other modes that refrigeration whether is needed between each room according to can interpolate that judge the current refrigeration situation between each room, it is of the invention to this not
It is limited.
Specifically, determining at least following two implementations of current refrigeration situation between at least two Room：
The first, the current refrigeration situation between at least two Room is determined according to the current switch states of at least one air door.
It should be noted that in addition to refrigerating chamber, having air door between other rooms, airdoor control can be installed on air door
Device, the state of each air door is obtained from air damper controller, if air door is closed, it is determined that need refrigeration between the room；Otherwise, it is determined that

It is the voltage for making the rotating speed of blower fan in first range of speeds in the case of current refrigeration；Blower fan is driven according to targeted load voltage
Operation, to cause the rotating speed of blower fan in first range of speeds.So, the load of blower fan is different in the case of different refrigeration,
By the corresponding relation between default refrigeration situation and load voltage, targeted load voltage is determined, according to targeted loads electricity
Voltage-controlled fan operation processed, to reduce influence of the wind speed change to rotation speed of fan, so that rotation speed of fan is stable attached in rotating speed of target
Closely, reduce wind cooling refrigerator because rotation speed change greatly caused by noise.
The method that blower fan speed stabilizing works in wind cooling refrigerator is controlled the embodiments of the invention provide a kind of, the present embodiment is with wind
Illustrated exemplified by cold refrigerator only refrigerating chamber and refrigerating chamber.As shown in figure 4, this method includes：
401st, determine whether to start blower fan.
Specifically, determined whether to need refrigeration between having family respectively according to the Current Temperatures and preset temperature between each room,
In the case of needing refrigeration between having family, it is determined that starting blower fan, step 402 is now performed；Otherwise, it determines not starting blower fan, now
Terminate.
402nd, in the case of it is determined that starting blower fan, started in first time period with the first load voltage control blower fan.
It should be noted that the first load voltage is the voltage that blower fan can be driven to start.It is preferred that, the first load voltage
It is the minimum voltage for driving blower fan to start.
It should be noted that due to electricity required when voltage required when blower fan starts is likely larger than blower fan stable operation
Pressure, if so controlling fan operation according to the first load voltage when starting for a long time, then the rotating speed of blower fan is likely larger than
Rotating speed of target required by blower fan stable operation, it is impossible to ensure the stable operation of blower fan, so needing control blower fan negative with first
The run time of voltage is carried, makes blower fan after start-up, but before rotating speed does not reach rotating speed of target also, just according to different refrigeration
Situation controls the load voltage of blower fan, makes the rotating speed of blower fan in first range of speeds.
Optionally, first time period is 1-3 seconds.
It should be noted that in order to control rotating speed no more than rotating speed of target of the blower fan in startup stage, except step 402 is logical
, can also be by obtaining the rotating speed of blower fan in real time, it is determined that whether rotating speed reaches that target turns in real time outside the method for crossing control time
It is fast or reaching rotating speed of target a times, wherein 0.5≤a≤0.9, in the case where reaching, it is determined that refrigeration situation, and according to system
Cold situation controls blower fan stable speed operation by corresponding load voltage；In the case where being not reaching to, it can continue according to first
Load voltage controls fan operation.
It should be noted that the load voltage for controlling blower fan is the method for the first load voltage, can be by adjusting duty
Can also be the first load by adjusting the resistance adjustment load voltage of partial pressure than adjusting load voltage for the first load voltage
Voltage, can also be the other method that can change that load voltage is the first load voltage, and the present invention is without limitation.
