Difference is 3Pa, i.e. the air outlet in air channel and the pressure difference of return air inlet is minimum with the difference of 2.5Pa, then control
The voltage of blower fan processed is 8.4V, and the rotating speed i.e. controlling blower fan is 1910rpm.When there being two default pressure
Difference and the air outlet in air channel are minimum with the difference of the pressure difference of return air inlet, then select default pressure less than normal
The voltage of difference correspondence is as the running voltage of blower fan.It is of course also possible to select default pressure difference bigger than normal
Corresponding voltage is as the running voltage of blower fan.
According to one embodiment of present invention, before step 104, including: refrigerator is currently located
Ambient temperature compares with preset temperature；When ambient temperature is less than preset temperature, according to pressure difference
The rotating speed of blower fan is controlled；When ambient temperature more than or equal to preset temperature time, control blower fan with
Preset rotation speed is run.
Refrigerator blower control method according to embodiments of the present invention, if the ambient temperature that refrigerator is currently located
More than preset temperature, illustrate that the ambient temperature that refrigerator is currently located is too high, the most directly control blower fan with in advance
If rotating speed runs, thus avoid ambient temperature too high between the temperature of room cause and compare large effect.
According to one embodiment of present invention, the ambient temperature that refrigerator is currently located is entered with preset temperature
Before the step that row compares, also include: judge whether to receive the request controlling blower fan start；If connecing
Receive the request controlling blower fan start, then ambient temperature is compared with preset temperature.
Refrigerator blower control method according to embodiments of the present invention, if blower fan off-duty, room between explanation
Temperature compare equilibrium, it is not necessary to control fan operation compartment temperature is adjusted；If received
To controlling the request that blower fan is started shooting, i.e. fan operation, ambient temperature is compared to preset temperature
The rotating speed of blower fan is controlled, it is to avoid be carried out such scheme the most under what circumstances, enters one
Achieve to step the accurate control to compartment temperature.
Fig. 2 shows the signal stream of refrigerator blower control method according to another embodiment of the invention
Cheng Tu.
As in figure 2 it is shown, refrigerator blower control method according to another embodiment of the invention, bag
Include:
Step 202, receives the request controlling blower fan start.
Step 204, it is judged that the ambient temperature that refrigerator is currently located is more than preset temperature (the most such as,
Preset temperature is 35 DEG C), when judged result is for being, enters step 206, otherwise, enter step
208。
Step 206, the ambient temperature being currently located when refrigerator is more than preset temperature, controls blower fan with electricity
Pressure 11.2V runs.
Step 208, obtains the scope at pressure difference △ P place, and pressure difference △ P refers to connect with a room
The air outlet in air channel and the pressure difference of return air inlet, specifically, the air outlet in air channel is with return air inlet respectively
Be placed with pressure transducer, detect the pressure at air port and return air inlet by pressure transducer, by terms of
Calculate the pressure difference of air outlet and return air inlet.
Step 210, if △ is P, < 2Pa (such as, Pa=1.2 Pascal) then controls blower fan with voltage
8.4V run.
Step 212, if 2Pa≤△ is P, < 4Pa then controls blower fan and runs with voltage 9.8V.
Step 214, if △ is P >=4Pa, then and control blower fan and run with voltage 11.2V.
In such scheme, room is put between refrigerator different loads, can be according to pressure transducer
Monitor the air outlet in the air channel connected with a room and the pressure of return air inlet, and feed back to master control borad, logical
Cross master control borad and calculate the pressure difference in air port and return air inlet, corresponding control instruction is sent to blower fan,
Control rotation speed of fan, thus reach the purpose of accurate temperature controller, so can actually used according to user
Situation is accurately freezed, and can save again energy consumption simultaneously.
