Fig. 3 is for illustrating that control device determines the flow chart of the processing of the revolving speed of box fan.In addition, in control device
In the case that 10 are microcomputer, it can also be handled by processor cores to realize control unit 101 described below
The processing carried out.
After control unit 101 has determined the revolving speed of compressor 4 according to outside air temperature, start the processing of Fig. 3.Firstly, control
Portion 101 processed judges that the revolving speed (revolving speed of last time) when whether the revolving speed of compressor 4 operates from the period of last time is changed
Become (step S101).
In the case where control unit 101 is judged as that change has occurred from the revolving speed of last time in the revolving speed of compressor 4, processing enters
Step S102.Control unit 101 does not correct the revolving speed of box fan 6, and is determined as reference rotation speed ω 2 (step S102).Then, it controls
Portion 101 processed maintains the rotational speed omega 2 of box fan 6 to be operated, until stopping compressor 4 (step S103).That is, control
It portion 101, will be in next cycle when the operating of compressor 4 in the case where changing the revolving speed of compressor 4 according to outside air temperature
Box fan 6 revolving speed maintain according to the revolving speed of compressor 4 determine reference rotation speed.
As a result, in the case where control unit 101 is according to the revolving speed of outside air temperature changed to change compressor 4, due to it
It influences, the prescribed limit (fiducial temperature T1 or more and T2 range below) of the mean temperature relative to refrigerating chamber 3 can be eliminated
The deviation of generation.But even if in the case where control unit 101 changes the revolving speed of compressor 4, the mean temperature of refrigerating chamber 3
It is also possible to not know within the limits prescribed.In the present embodiment, control unit 101 is pressed by changing in next cycle
The revolving speed of box fan 6 when contracting machine 4 operates, is controlled, so that the temperature inside the box of refrigerating chamber 3 becomes suitable value.
On the other hand, in step s101, it is judged as the revolving speed of compressor 4 not from the revolving speed of last time in control unit 101
In the case where change, processing enters step S104.Control unit 101 judges being averaged for the refrigerating chamber 3 being stored in storage unit 102
Whether temperature is less than 1 threshold value, that is, fiducial temperature T1.It is judged as that the mean temperature of refrigerating chamber 3 compares fiducial temperature in control unit 101
In the case that T1 is small, processing enters step S105.The revolving speed (step S105) of the reduction box fan 6 of control unit 101.That is, control
The revolving speed of box fan 6 is determined as the value smaller than reference rotation speed ω 2 i.e. ω 1 by portion 101.Then, control unit 101 maintains wind in case
The rotational speed omega 1 of fan 6 is operated, until stopping compressor 4 (step S106).
On the other hand, in step S104, it is judged as that the mean temperature of refrigerating chamber 3 is benchmark temperature T1 in control unit 101
In the case where above, processing enters step S107.Control unit 101 judges whether the mean temperature of refrigerating chamber 3 is greater than the 2nd threshold value i.e.
Fiducial temperature T2.In addition, fiducial temperature T2 is set as the value bigger than fiducial temperature T1.It is judged as the flat of refrigerating chamber 3 in control unit 101
In the case that equal temperature is bigger than fiducial temperature T2, processing enters step S108.Control unit 101 improves the revolving speed (step of box fan 6
Rapid S108).That is, the revolving speed of box fan 6 is determined as the value bigger than reference rotation speed ω 2 i.e. ω 3 by control unit 101.Then, it controls
Portion 101 maintains the rotational speed omega 3 of box fan 6 to be operated, until stopping compressor 4 (step S109).
In step s 107, it is judged as that the mean temperature of refrigerating chamber 3 is the situation of benchmark temperature T2 or less in control unit 101
Under, processing enters step S110.Control unit 101 does not correct the revolving speed of box fan 6, and is determined as 2 (step of reference rotation speed ω
S110).Then, control unit 101 maintains the rotational speed omega 2 of box fan 6 to be operated, (step until stopping compressor 4
S111)。
In addition, control unit 101 determines wind according to the revolving speed of compressor 4 and in the case of determination according to control sequence (not shown)
The reference rotation speed ω 2 and its corrected value ω 1 and ω 3 of fan 6.Specific value depends on the capacity of refrigerator 1 and the appearance of compressor 4
Amount, can survey refrigerator 1 and each combination of compressor 4, set optimum value.
In addition, control unit 101 the mean temperature for being judged as refrigerating chamber 3 be benchmark temperature T1 or more and fiducial temperature T2 with
(it is " no " in step S104 and is in step s 107 " no ") in the case where lower, can also further judges that outside air temperature is
It is no to be in ascendant trend.At this point, processing enters step in the case where control unit 101 is judged as that outside air temperature does not have ascendant trend
Rapid S110.In the case where control unit 101 is judged as that outside air temperature is in ascendant trend, control unit 101 turns box fan 6
Speed is determined as the value bigger than reference rotation speed ω 2 i.e. ω 3.
That is, even if being 1 threshold value, that is, fiducial temperature T1 or more in 3 mean temperature of refrigerating chamber and in 2 threshold values, that is, benchmark temperature
It spends in T2 situation below, when outside air temperature is in ascendant trend, control unit 101 also carries out determination below.That is, control unit
101 make the revolving speed of the box fan 6 when compressor 4 operates in next cycle be higher than reference rotation speed ω 2.Here, in outside
In the case that temperature is in ascendant trend, the ratio of the heat leak amount of refrigerating chamber 3 is bigger than the ratio of the heat leak amount of freezing chamber 2.
That is, refrigerating chamber 3 is difficult to cool down relative to freezing chamber 2.In the present embodiment, due to the rotating ratio reference rotation speed of box fan 6
ω 2 is high, therefore the cold air in case further recycles.As a result, the cold air of freezing chamber 2 is recycled by refrigerating chamber 3, therefore
The ratio of heat leak amount can be kept as far as possible equal.Therefore, it operates and stops in the temperature inside the box of compressor 4 based on freezing chamber 2
In the case where only, the cooling insufficient situation of refrigerating chamber 3 can be prevented.
Similarly, control unit 101 is in the mean temperature for being judged as refrigerating chamber 3 for benchmark temperature T1 or more and in fiducial temperature
(it is " no " in step S104 and is in step s 107 " no ") in T2 situation below, can also further judges external gas
Whether temperature is in downward trend.At this point, in the case where control unit 101 is judged as that outside air temperature is not at downward trend, processing
Enter step S110.In the case where control unit 101 is judged as that outside air temperature is in downward trend, control unit 101 is by wind in case
The revolving speed of fan 6 is determined as the value smaller than reference rotation speed ω 2 i.e. ω 1.
That is, even if the mean temperature in refrigerating chamber 3 is in 1 threshold value, that is, fiducial temperature T1 or more and in the 2nd threshold value
In fiducial temperature T2 situation below, when outside air temperature is in downward trend, control unit 101 carries out determination below.That is, control
Portion 101 processed makes the revolving speed of the box fan 6 when compressor 4 operates in next cycle lower than reference rotation speed ω 2.It is as a result,
The mean temperature of the refrigerating chamber 3 in the period according to last compression machine 4 is set to be judged as the revolving speed that can not correct box fan 6
In the case where, in the case where outside air temperature is in downward trend, reduce the revolving speed of box fan 6.This is because in external gas
Temperature in the case where the downward trend, the ratio of the heat leak amount of refrigerating chamber 3 relative to the heat leak amount of freezing chamber 2 ratio compared with
It is small.That is, refrigerating chamber 3 is easy cooling relative to freezing chamber 2.Therefore, it is operated in the temperature inside the box of compressor 4 based on freezing chamber 2
And in the case where stopping, the cooling of refrigerating chamber 3 is possible to terrifically carry out.Therefore, by reducing the revolving speed of box fan 6, energy
Enough inhibit the sub-cooled of refrigerating chamber 3.
In this way, according to the present embodiment, mean temperature of the control unit 101 based on refrigerating chamber 3 and threshold value (the 1st threshold value or the 2nd
Threshold value) comparison result, next cycle lieutenant colonel's positive compression machine 4 operate when box fan 6 revolving speed.Specifically, control
Portion 101 processed is in the case where the mean temperature of refrigerating chamber 3 is smaller than 1 threshold value, that is, fiducial temperature T1, in next cycle, makes to press
The rotating ratio reference rotation speed ω 2 of box fan 6 when contracting machine 4 operates is low.In addition, mean temperature of the control unit 101 in refrigerating chamber 3
In the case where greater than 2 threshold values, that is, fiducial temperature T2 bigger than 1 threshold value, that is, fiducial temperature T1, in next cycle, make to press
The revolving speed of box fan 6 when contracting machine 4 operates is higher than reference rotation speed ω 2.
That is, controlling the feelings of operating and the stopping of compressor 4 on the basis of by the temperature inside the box of 1 storeroom, that is, freezing chamber 2
Under condition, 2 storerooms, that is, refrigerating chamber 3 mean temperature not in defined range (fiducial temperature T1 or more and T2 model below
