In, refrigeration air door 203 is in the wind inlet channel 200 being set to inside central sill 120.It is also possible to by being set to return air
Return air damper in air duct 300 controls the influx of return air.
Fig. 2 is the schematic diagram of the control method of side by side combination refrigerator 100 according to an embodiment of the invention.In some implementations
In example, the control method of the side by side combination refrigerator 100 of the embodiment of the present invention includes:
S202: the temperature in mixed wind region 102 is obtained, the first temperature is obtained；
S204: based on fiducial temperature compared with the first temperature, the aperture of refrigeration air door 203 is adjusted.
Fiducial temperature herein is the pre-set target temperature in mixed wind region 102.For example it is assumed that mixed wind region 102 is default
Target temperature is -5 DEG C to -2 DEG C, and the first temperature of acquisition is -7 DEG C, thinks that the first temperature is lower than fiducial temperature (or its model at this time
Enclose the lower limit value in value), the cold wind into mixed wind region 102 is excessive, and the aperture of control refrigeration air door 203 reduces.For another example false
The pre-set target temperature in surely mixed wind region 102 is -5 DEG C to -2 DEG C, and the first temperature of acquisition is 0 DEG C, thinks the first temperature at this time
Higher than fiducial temperature (or upper limit value in its value range), the cold wind into mixed wind region 102 is very few, control refrigeration air door 203
Aperture increase.
In further embodiments, in step S104, fiducial temperature is the pre-set target temperature of storage area 101, the control
Method processed is to obtain the temperature of storage area 101；Pre-set target temperature and acquired storage area based on storage area 101
The comparison of 101 temperature adjusts the influx for being sent into the mixed airflow of storage area 101.The storage area of refrigerator room 130
101 pre-set target temperature can be -5 DEG C to 7 DEG C, such as -5 DEG C to 7 DEG C, -4 DEG C to 0 DEG C, -5 DEG C, -2 DEG C, 3 DEG C, 7 DEG C.
The adjusting of the influx of mixed airflow preferably adjusts the revolving speed for being set to the mixed wind blower 442 in mixed wind region 102
To adjust the influx of mixed airflow.Fig. 3 is the control method of side by side combination refrigerator 100 in accordance with another embodiment of the present invention
Schematic diagram.In some embodiments, the control method of the side by side combination refrigerator 100 of the embodiment of the present invention includes:
S302: the temperature of storage area 101 is obtained, second temperature is obtained；
S304: based on fiducial temperature compared with second temperature, the revolving speed of mixed wind blower 442 is adjusted.
Herein, fiducial temperature is the pre-set target temperature of storage area 101.For example it is assumed that the default mesh of storage area 101
Marking temperature can be -5 DEG C to 7 DEG C, and the second temperature of acquisition is -7 DEG C, think at this time second temperature lower than fiducial temperature (or its
Lower limit value in value range), the mixed airflow into storage area 101 is excessive, and the revolving speed for controlling mixed wind blower 442 reduces.Again
For example it is assumed that the pre-set target temperature of storage area 101 is -5 DEG C to 7 DEG C, the second temperature of acquisition is 10 DEG C, thinks the at this time
Two temperature are higher than fiducial temperature (or upper limit value in its value range), and the mixed airflow into storage area 101 is very few, and control is mixed
The revolving speed of wind blower 442 increases.The control method of the side by side combination refrigerator 100 of the embodiment of the present invention is by controlling mixed wind region 102
The revolving speed of mixed wind blower 442 influx of mixed airflow for being sent into storage area 101 is adjusted, control simple easily behaviour
Make.
When the side by side combination refrigerator 100 of the embodiment of the present invention is based on single system refrigeration, the flow chart of control method such as Fig. 4 institute
Show.In some embodiments, the control method of the side by side combination refrigerator 100 of the embodiment of the present invention includes:
S402: judge whether freezing compartment 140 reaches starting point.The ideal of freezing compartment 140 is generally -15 using temperature
DEG C, the starting point of freezing compartment 140 is that the Current Temperatures of freezing compartment 140 are higher than its ideal and (or ideal are used using temperature
The upper limit value of temperature range value), such as Current Temperatures are -10 DEG C, then it is assumed that freezing compartment 140 reaches starting point.
S404: if the judging result of step S402 be it is yes, i.e. freezing compartment 140 reaches starting point, control cooling blower fortune
Row.
S406: after cooling blower runs a period of time, control compressor operation.
S408: after compressor runs a period of time, control freezing fan operation.Usually after cooling blower runs 1min
Compressor is run, the operation freezing blower after compressor runs 1min.
S410: if the judging result of step S402 be no or step S408 in freezing fan operation for a period of time after, sentence
Whether disconnected refrigerator room 130 reaches starting point.The ideal of refrigerator room 130 is generally -5 DEG C to 7 DEG C using temperature, refrigerator room
130 starting point is that the Current Temperatures of the storage area 101 of refrigerator room 130 are higher than its ideal (or ideal makes using temperature
With the upper limit value of temperature range value), such as Current Temperatures are 10 DEG C, then it is assumed that refrigerator room 130 reaches starting point.
S412: if the judging result of step S410 be it is yes, i.e. refrigerator room 130 reaches starting point, control refrigeration air door 203
Open the first predetermined angle.First predetermined angle can be any angle, consider from the convenience of control, if refrigeration air door 203
Maximum opening be 90 °, the first predetermined angle is preferably 40-50 °, for example is 42 °, 45 ° or 50 °.
S414: it controls mixed wind blower 442 and runs, continue for some time.
S416: the temperature in mixed wind region 102 is obtained, the first temperature is obtained.
S418: compare whether the first temperature meets fiducial temperature lower limit value < the first temperature < fiducial temperature upper limit value.Example
Such as by taking fiducial temperature is -5 DEG C to -2 DEG C as an example, fiducial temperature lower limit value is -5 DEG C, and fiducial temperature upper limit value is -2 DEG C.It is assumed that obtaining
The first temperature obtained is -7 DEG C, can determine whether out that the first temperature is unsatisfactory in fiducial temperature lower limit value < the first temperature < fiducial temperature
Limit value.The first temperature for again assuming that acquisition is 0 DEG C, and similarly, the first temperature is unsatisfactory for fiducial temperature lower limit value the first temperature of <
< fiducial temperature upper limit value.
If the judging result of step S418 be it is yes, status is kept, until carrying out step S410 again.
S420: if the judging result of step S418 is no and the first temperature < fiducial temperature lower limit value, control refrigeration wind
Door 203 reduces the second predetermined angle.Second predetermined angle can be any angle for being no more than the first predetermined angle, for example, the
One predetermined angle is 45 °, then the second predetermined angle can be 0 ° -45 ° of arbitrary value, for example be set as 5 °, 10 °, 25 °.
S422: after the completion of step S420, controlling mixed wind blower 442 and run the second preset time, then operating procedure again
S416, circulation step S416, S418, until the judging result of step S418 is yes.When second preset time can be shorter
Between, it is also possible to longer time, for example, for 1min, 10min or more than 30min.
S424: if the judging result of step S418 is no and the first temperature > fiducial temperature upper limit value, control refrigeration wind
Door 203 increases third predetermined angle.For maximum opening to refrigerate air door 203 is 90 °, third predetermined angle be can be arbitrarily
No more than the angle of the complementary angle of the first predetermined angle, for example, the first predetermined angle is 40 °, then third predetermined angle can be 0 °-
50 ° of arbitrary value, for example it is set as 5 °, 10 °, 30 °.
S426: after the completion of step S424, controlling mixed wind blower 442 and run third preset time, then operating procedure again
