Embodiment
In conjunction with the accompanying drawings the present invention is described in further detail below by embodiment.
Air-cooled defrost refrigerator of the present invention is arranged refrigeration evaporator and refrigerating evaporator respectively at reefer and refrigerating chamber, and utilizes refrigeration blower fan and freezing blower fan formation ducting system separately respectively, has realized the independently air-cooled control in each chamber.In reefer, rationally adjust the duty of refrigeration blower fan according to the temperature of temperature in the reefer and refrigeration rapid steamer, make the air constantly circulation under the effect of refrigeration blower fan in the reefer, bring the steam of evaporator surface into reefer, thereby guarantee that reefer keeps higher humidity.
As shown in Figure 1, the control method of preserving moisture of the wind cooling refrigerator of an embodiment of the present invention may further comprise the steps:
Step S101: by being installed in the temperature T in devices such as the refrigerated storage temperature sensor detection reefer in the reefer
L, this testing process can continue to carry out, in case T
LChange and enter step S102 immediately,, reduce energy consumption, also can regularly detect in order to alleviate the work load of temperature sensor and other working cells.
Step S102: according to default first temperature range and second temperature range, to T
LSize judge.Two kinds of temperature ranges can be provided with according to concrete needs.
Preferably, first temperature range is got T
L〉=t
1, second temperature range is got T
L＜t

2Generally, the refrigerated storage temperature of refrigerator remains on 1～6 ℃, therefore t can be set
1Be 6 ℃, t
2Be 1 ℃, can also set t according to the temperature of user on operation interface certainly
1And t
2Concrete numerical value.
Step S103:T
LBe in first temperature range? be then to enter step S104, otherwise enter step S105.
Step S104: the rotating speed of adjusting the refrigeration blower fan is r
1, make the air in the reefer under the effect of refrigeration blower fan, carry out sufficient exchange heat with refrigeration evaporator.The refrigeration evaporator of present embodiment and refrigerating evaporator all preferably adopt defrost effect evaporator fin preferably, regularly by the mode defrost of heated filament heating, the water vapor that produces in the defrost process is attached to the pipeline and the fin surface of evaporator fin for evaporator fin.In the exchange heat process, because this step makes the refrigeration blower fan that bigger rotating speed is provided, a lot of water vapor on the refrigeration evaporator are brought in the reefer, thereby improved the interior humidity of reefer, then can get back to step S101 and continue to detect, up to obtaining next testing result.
In this step, if T
L〉=t
1, then reefer starts refrigeration, for example can make condensing agent lead to refrigeration evaporator by the mode conducting refrigeration kapillary of switching solenoid valve, avoids the temperature of reefer too high.
Step S105:T
LBe in second temperature range? be then to enter step S106, continue to detect otherwise get back to step S101.
Step S106: by being arranged on the temperature T of devices such as the defrost temperature sensor detection evaporator on the refrigeration evaporator
H, this testing process can continue equally to carry out or regularly detect.
If T
L＜t
2, then reefer stops refrigeration, for example can close freezing kapillary by the mode of switching solenoid valve, makes condensing agent directly lead to refrigerating evaporator, avoids the temperature of reefer low excessively.
Step S107: to T
HSize judge, and according to the rotating speed of judged result adjustment refrigeration blower fan.For example can set two or more temperature ranges as required flexibly, the corresponding a kind of rotating speed that refrigerates blower fan of each temperature range, and T
HMore little, the rotating speed of corresponding refrigeration blower fan is big more, i.e. T
HMore little, the water vapor that stops on the evaporator fin is few relatively more, and the refrigeration blower fan need provide bigger air quantity to promote the steam circulation, thus the temperature of Keep cool rationally, effectively chamber.
Present embodiment is carried out fuzzy control by the rotating speed to the refrigeration blower fan, and the steam that refrigeration evaporator surface defrost is produced is taken back in the reefer as much as possible.Because the rotating speed of refrigeration blower fan is rationally adjusted according to the temperature of reefer and the temperature of evaporator, therefore reduced the power consumption of refrigeration blower fan.
Further, because a lot of steam on refrigeration evaporator surface are brought into reefer, frosting on the refrigeration evaporator reduces relatively, so defrost periods that can prolong reefer, promptly reduce the work number of times of reefer defrost heater strip in the unit interval, reduce power consumption equally, reached energy-conservation effect.
As shown in Figure 2, the control method of preserving moisture of the wind cooling refrigerator of the another kind of embodiment of this present invention may further comprise the steps:
Step S201: by being installed in the temperature T in the refrigerated storage temperature sensor reefer in the reefer
L
Step S202: to T
LSize judge T whether
L〉=t
1Be then to enter step S203, otherwise enter step S205.
Step S203: switching solenoid valve, conducting is sent to the refrigeration kapillary of refrigeration evaporator with condensing agent, starts the reefer refrigeration.
Step S204: the rotating speed of adjusting the refrigeration blower fan is r
1, make to have enough air quantity in the reefer, thereby promote the steam in the reefer to circulate, improve humidity.
Step S205: T whether
L＜t
2Be then to enter step S206, continue to detect otherwise get back to step S201.
Step S206: this moment, reefer did not need refrigeration, and switching solenoid valve is closed the refrigeration kapillary that condensing agent is sent to refrigeration evaporator, stopped the reefer refrigeration.
Step S207: by being arranged on the temperature T of the defrost temperature sensor detection refrigeration evaporator on the refrigeration evaporator
HThereby, adjust the rotating speed that refrigerates blower fan.
Step S208: to T
HSize judge T whether
H＜t
3Be then to enter step S209, otherwise enter step S210.
Step S209: the rotating speed that will refrigerate blower fan is adjusted into r

Step S210: t whether
3≤ T
H＜t
4Be then to enter step S211, otherwise enter step S212.
Step S211: the rotating speed that will refrigerate blower fan is adjusted into r
3
Step S212: T whether
H〉=t
4Be then to enter step S213.
Step S213: the rotating speed that will refrigerate blower fan is adjusted into r

More than in each step, t
3Be first preset temperature, t
4Be second preset temperature, and r
1＞r
2＞r
3＞r
4, each preset temperature and rotating speed can also can be set up on their own by the user by producer's default setting.
Above step S209, S211 or S213 are behind the rotating speed of adjusting the refrigeration blower fan, and sense cycle or the lasting needs that detect that can be default according to the defrost temperature sensor return the temperature that step S207 continues to detect refrigeration evaporator; Also can get back to step S201, when the refrigerated storage temperature sensor detects the refrigeration indoor temperature once more, and judge T according to default sense cycle of refrigerated storage temperature sensor or the needs that continue to detect
L〉=t
1The time, the defrost temperature sensor can stop to detect, and perhaps stops its detection signal is handled.
