Embodiment shall fall within the protection scope of the present invention.
The embodiment of the present invention provides a kind of control method of single system wind cooling refrigerator, as shown in Figure 1, the method includes：
The temperature of the refrigerating chamber of step 101, the ambient temperature for obtaining refrigerator and refrigerator.
Sequencing of the embodiment of the present invention for the temperature of the ambient temperature of acquisition refrigerator and the refrigerating chamber of refrigerator
It does not limit.In practical applications, the ambient temperature of refrigerator and the refrigeration of refrigerator are generally acquired by temperature sensor
The temperature of room.
If step 102, ambient temperature are less than the first temperature threshold, the temperature of refrigerating chamber is less than second temperature threshold value,
And when the compressor shutdown of refrigerator, the heating member work in the main air duct of refrigerator is controlled.
Wherein, first temperature threshold and the second temperature threshold value are pre-set value, people in the art
Member can be set according to actual conditions, and it is not limited in the embodiment of the present invention.In view of cold during refrigeration for refrigerator
Hide the temperature variations of room, it is considered that when the temperature of refrigerating chamber is less than 0 DEG C, refrigerating chamber just needs to carry out temperature-compensating to prevent
Indoor food is only refrigerated to be damaged by frost, thus second temperature threshold value is typically chosen as 0 DEG C~-1 DEG C.
Exemplary, the first temperature threshold is 10 DEG C, and second temperature threshold value is 0 DEG C, and when getting, ambient temperature T1 is small
When 10 DEG C, then it is assumed that ambient temperature is relatively low, when the temperature T2 for getting refrigerating chamber is less than 0 DEG C, then shows cold at this time
The temperature for hiding room is too low, and raising temperature is needed to be damaged by frost to prevent from refrigerating indoor food；It is shut down when the compressor of refrigerator is in
When state, then it represents that refrigerator is not freezing at this time, the heating member work in the main air duct of refrigerator at this moment can be controlled, to add
Air in hot main air duct.
It should be noted that the heating member can be wind cooling refrigerator is arranged heating on an evaporator to defrost
Silk, can also be the heating member being exclusively provided in main air duct, it is not limited in the embodiment of the present invention.Preferably, when using
When heater strip on the evaporator of wind cooling refrigerator is as heating member, additional setting heating member can not had to, to reduce refrigerator
The setting quantity of interior component, saves the cost of refrigerator.
Temperature in step 103, acquisition main air duct.
After heating member in the main air duct using refrigerator heated the air in main air duct, temperature sensor can be utilized
The temperature in main air duct is acquired, to judge whether the temperature in main air duct has been improved.
If the temperature in step 104, main air duct is more than third temperature threshold, control refrigerator enters low temp compensating pattern,
The low temp compensating pattern includes：The wind turbine of refrigerator is operated with first direction, and the air door of refrigerating chamber is opened, the return air inlet of refrigerating chamber
It opens, the return air inlet of the freezing chamber of refrigerator is closed；Wherein, the rotation direction phase of the first direction and wind turbine when refrigeration for refrigerator

Wherein, the third temperature threshold be pre-set value, those skilled in the art can according to actual conditions into
Row setting, it is not limited in the embodiment of the present invention.It should be noted that the third temperature threshold is more than the second temperature
Threshold value.Exemplary, third temperature threshold is 5 DEG C, when getting the temperature T3 in main air duct more than 5 DEG C, then it is assumed that main air duct
Interior air is heated, can carry out the temperature-compensating of refrigerating chamber at this time, thus is controlled refrigerator and entered low temp compensating pattern.
The low temp compensating pattern includes：The wind turbine of refrigerator is operated with first direction, the first direction and refrigeration for refrigerator
The rotation direction of Shi Fengji is on the contrary, i.e. the wind turbine of refrigerator reverses；The air door of refrigerating chamber is opened, and the return air inlet of refrigerating chamber is opened, i.e.,
The air-supply passage of refrigerating chamber is opened；The return air inlet of the freezing chamber of refrigerator is closed, i.e., the air-supply passage of freezing chamber is closed.
As shown in Figure 3 and Figure 4, Fig. 3 is wind circulation route schematic diagram when refrigerator 30 freezes in the prior art, and Fig. 4 is this
Wind circulation route schematic diagram after low temp compensating pattern is opened in inventive embodiments.When refrigerator 30 freezes in the prior art, wind turbine
It rotates forward, the hot gas in freezing chamber 32 and refrigerating chamber 31 is passed through 31 bottom of return air inlet and refrigerating chamber of 32 bottom of freezing chamber by wind turbine respectively
The return air inlet in portion is drawn into main air duct, these hot gas become cold air after the evaporator heat exchange in main air duct, then pass through
It is respectively fed in freezing chamber 32 and refrigerating chamber 31 by the air outlet of 32 air outlet of freezing chamber and refrigerating chamber 31.And implement in the present invention
In example, since only temperature-compensating need to be carried out to refrigerating chamber 31, thus needs to open the air-supply passage of refrigerating chamber 31, close freezing chamber
32 air-supply passage, is reversed using wind turbine, and the hot gas generated in main air duct is sent to via the return air inlet of 31 bottom of refrigerating chamber
In refrigerating chamber 31, since hot-air density is small, thus the hot-air entered in refrigerating chamber 31 can move upwards so that entire cold
The temperature rise for hiding room 31, realizes the temperature-compensating to refrigerating chamber 31 with this, the food in refrigerating chamber 31 is prevented to be damaged by frost.
It should be noted that if in a step 102, being just immediately controlled after controlling the work of the heating member in the main air duct of refrigerator
Refrigerator enters low temp compensating pattern, then the cold wind not heated also in the main air duct of refrigerator can be caused to blow to refrigerating chamber, in this way
The temperature of refrigerating chamber may be further decreased, aggravation refrigerates the degree that indoor food is damaged by frost.Thus, in a step 102,
After controlling the heating member work in the main air duct of refrigerator, also needs to execute step 103, obtain the temperature in the main air duct of refrigerator, when
When temperature in the main air duct of refrigerator is more than third temperature threshold, that is, think that the air in main air duct is heated, it at this moment can be with
Control refrigerator enters low temp compensating pattern, i.e., will be heated air in air duct and be sent in refrigerating chamber, to improve in refrigerating chamber
Temperature.

If step 106, the temperature of refrigerating chamber are more than or equal to four temperature thresholds, control refrigerator exits low temp compensating
Pattern, wherein the 4th temperature threshold is more than second temperature threshold value.
4th temperature threshold is pre-set value, and those skilled in the art can set according to actual conditions
Fixed, it is not limited in the embodiment of the present invention.
After control refrigerator enters low temp compensating pattern, since the hot wind in main air duct has been sent to refrigerating chamber by wind turbine
It is interior so that the temperature of refrigerating chamber increases.And the temperature of refrigerating chamber is too high can destroy cold storage effect, thus can control refrigerator into
After entering low temp compensating pattern, the temperature of a refrigerating chamber is obtained at interval of preset time, be more than when the temperature of refrigerating chamber or
When equal to four temperature thresholds, control refrigerator exits low temp compensating pattern, i.e. wind turbine stops reversing, and heating member is stopped.This
Sample prevents temperature of refrigerating chamber excessively high and destroys cold storage effect.
Optionally, after control refrigerator enters low temp compensating pattern, the method further includes：Obtain the temperature in main air duct
Degree；If the temperature in main air duct is more than or equal to five temperature thresholds, control refrigerator exits low temp compensating pattern, wherein
5th temperature threshold is more than third temperature threshold.
5th temperature threshold is pre-set value, and those skilled in the art can set according to actual conditions
Fixed, it is not limited in the embodiment of the present invention.
Since low temp compensating is that the hot wind in main air duct is sent in refrigerating chamber, to improve the indoor temperature of refrigeration, thus
If the temperature in main air duct is more than or equal to five temperature thresholds, i.e., when the temperature in main air duct is higher, it is believed that cold
Hide indoor temperature and be also increased to suitable degree, thus refrigerator can be controlled at this time and exit low temp compensating pattern, stop after
It is continuous that temperature-compensating is carried out to refrigerating chamber, it prevents from destroying cold storage effect since temperature of refrigerating chamber is too high.
Further, refering to what is shown in Fig. 5, Fig. 5 is the enlarged drawing of a-quadrant in Fig. 4, refrigerator 30 includes weatherseal, weatherseal
It is arranged at the return air inlet 321 of freezing chamber 32；The return air inlet 321 of freezing chamber 32 can be closed by the weatherseal.It is mended in low temperature
It repays in pattern, the hot gas in main air duct enters in freezing chamber 32 in order to prevent, needs the returning freezing chamber 32 using weatherseal
Air port 321 is closed.In practical applications, weatherseal can be air curtain or air door etc., and it is not limited in the embodiment of the present invention,
In view of the return air inlet 321 of the freezing chamber 32 of general refrigerator is larger, air door setting is more difficult, thus preferably, being made using air curtain
