30min but be no more than 60min when, control blower by third revolving speed operation can meet cooling demand, at this time blower press normal function
Consumption operating, such as run with the voltage of 8-9V, wherein 8-9V is the normal operating voltage of wind cooling refrigerator blower.When the compartment temperature
When duration in monitoring section alreadys exceed 60min, need quickly to reduce compartment temperature, at this moment blower just needs one
Relatively high revolving speed operates to reduce compartment temperature, such as with the voltage of 12V.In the duration that monitoring compartment temperature is kept
When, if the refrigerator room temperature obtained in real time does not monitor section in corresponding compartment temperature, refrigerator rotation speed of fan controls program will
Again adjustable strategies are determined according to circumstance temperature to control blower by corresponding revolving speed and run.
It is to be understood that blower is driven by a motor, motor is a kind of power device for converting electrical energy into mechanical energy, wind
Machine is to improve gas pressure by the mechanical energy of transformation and supply gas side by side the machinery of body, rotation speed of fan can be controlled by voltage, with most
For number refrigerator rotation speed of fan, it is generally divided into high revolving speed and the slow-speed of revolution, setting voltage is usually 12V when high revolving speed, when the slow-speed of revolution
It is usually 9V that voltage, which is arranged, that is, the reference voltage of the first revolving speed of setting in the present embodiment is 12V, the ginseng of third revolving speed
Examining voltage is 9V.And most of refrigerator rotational speed regulation range gradients are insufficient, need and to meet different use environments from energy conservation
From the aspect of, the present invention is arranged three-level revolving speed and controls, that is, includes high revolving speed, rated speed (or middle revolving speed) and the slow-speed of revolution, press
Flexible control, more energy saving have been carried out according to duration length of the refrigerator room temperature in compartment temperature monitoring section,
The lasting situation of change of compartment temperature is considered simultaneously, and temperature control regulation is also more accurate.
It further, is that wind cooling refrigerator rotation speed of fan control method the 4th of the present invention is real please also refer to Fig. 1 and Fig. 4, Fig. 4
The flow diagram of example is applied, in the present embodiment, step S30 further include:
Step S35, when adjustable strategies are second adjustment strategy and the compartment temperature is greater than default compartment temperature threshold value,
Monitoring compartment temperature is maintained at the duration in compartment temperature monitoring section；
Step S36, judges whether the duration is greater than T3, and wherein T3 is third preset time；If so, executing step
Rapid S37, if it is not, thening follow the steps S38；
Step S37, control blower are run by the 4th revolving speed；
Step S38, control blower are run by the 5th revolving speed, wherein the 5th revolving speed is less than the 4th revolving speed.
When the refrigerator room temperature is greater than default compartment temperature threshold value, need to the refrigerator room temperature obtained in real time
The duration for being maintained at the compartment temperature is monitored, and different rotation speed of fan is then determined according to the length of duration.
That is, second adjustment strategy includes: under initiating events, when the duration being less than or equal to T3, control blower presses the 5th
Revolving speed operation, wherein the 5th revolving speed can be consistent with the third revolving speed in step S33 in the first strategy, it can also be according to refrigerator
The practical revolving speed that operates normally is configured.If blower is run with the 5th revolving speed, refrigerator room temperature is still greater than default room temperature
Threshold value is spent, making the duration is more than T3, can control blower and runs by the 4th revolving speed, wherein the 4th revolving speed can be with the first strategy
Middle step S34 is consistent with the first revolving speed in S41, can also be determined according to the actual speed of blower high-speed cruising.We
Case is after determining that second adjustment strategy is controlled according to environment temperature, according to the length of refrigerator room temperature duration dynamic
Rotation speed of fan is adjusted, keeps the control of refrigerator room temperature more accurate.
Wherein, the default compartment temperature threshold value in second adjustment strategy can it is consistent with the value of b in the first adjustment strategy or
Inconsistent, third preset time T 3 can be consistent with the T1 in the S32 in the first adjustment strategy or be set according to actual conditions.One
As refrigerator refrigerating temperature range at 0~12 DEG C, refrigerated storage temperature is more than that refrigeration effect is not achieved in 12 DEG C of refrigerators, be not achieved refrigeration
For effect, it is 12 DEG C that default compartment temperature threshold value, which is arranged, T3 be 30min for example, when compartment temperature is greater than 12 DEG C and
When duration is not up to 30min, blower is run by the practical normal operation revolving speed of refrigerator, such as can with the voltage operation of 9V
Meet cooling demand；It when above-mentioned compartment temperature is continued above 30min, needs as early as possible to reduce compartment temperature, control blower is pressed
High revolving speed operation, such as run with the voltage of 12V.When monitoring the duration that compartment temperature is kept, if what is obtained in real time is cold
It hides compartment temperature and does not monitor section in corresponding compartment temperature, program or processing determine that adjustable strategies control wind according to circumstance temperature again
Machine is run by corresponding revolving speed.
Further, continuing with referring to Fig. 1 and Fig. 4, in the present embodiment, step S40 further include:
Step S43, when adjustable strategies are second adjustment strategy and compartment temperature is less than or equal to default compartment temperature threshold
When value, control blower is run by the 5th revolving speed.
When the refrigerator room temperature is less than or equal to default compartment temperature threshold value, do not need to supervise the duration
It surveys, directly controls blower and run by the 5th revolving speed.
By taking default 12 DEG C of compartment temperature threshold value as an example, when compartment temperature is less than or equal to 12 DEG C, compartment temperature is at this time
In the normal refrigerating temperature range of refrigerator, so not needing to be monitored the time, blower can be directly controlled and run by the 5th revolving speed,
5th revolving speed can be consistent with the 5th revolving speed in S38, can be configured according to the practical normal operation revolving speed of refrigerator, example
Such as run with the voltage of 9V.
When environment temperature is higher, the blower slow-speed of revolution is no longer satisfied cooling demand, and blower needs to maintain higher turn
Speed could reduce compartment temperature as early as possible, and blower is by the flexible switching between different rotating speeds, so that temperature controls in refrigerator compartment
It is more accurate.
It is to be understood that second adjustment strategy is executed when environment temperature is greater than default environment temperature threshold value, it is outer at this time
Boundary's environment temperature and refrigerator room temperature-difference are larger, the air flow rate for needing to generate when refrigerator room keeps mutually synthermal
Accelerate, so being regulated and controled in second adjustment strategy using second level, does not turn using in the first adjustment strategy including low-power consumption
The three-level control methods of speed.
Optionally, in other embodiments, default shutdown temperature and default turn-on temperature can also be set, it is cold for preventing
Hiding compartment temperature is too low, and indoor article damages between pair.It is specific to can be when executing, when detecting compartment temperature lower than pre-
If when shutdown temperature, control blower shuts down, and after compartment temperature goes back up to default turn-on temperature, control blower starting.
