Below in conjunction with control method and the wind cooling refrigerator of accompanying drawing description according to the wind cooling refrigerator of the embodiment of the invention.
Fig. 1 is the flow chart of the control method of wind cooling refrigerator according to an embodiment of the invention.As shown in Figure 1, the control method of wind cooling refrigerator comprises the steps: according to an embodiment of the invention
Step S101: in the wind cooling refrigerator process of refrigerastion, judge whether wind cooling refrigerator meets the defrost condition.
Particularly, the evaporimeter of wind cooling refrigerator is arranged in the refrigerating chamber usually, and also there is an air channel between refrigerating chamber and the refrigerating chamber, near the air channel, also be provided with freezing blower fan, in the compressor cooling process, freezing blower fan moves simultaneously, thereby cold wind in the refrigerating chamber is delivered to refrigerating chamber with to refrigerating chamber refrigeration from the air channel, and accelerates heat transfer rate in the refrigerating chamber.After wind cooling refrigerator is long in the following working time of refrigeration mode, be positioned at and occur relatively serious situation of frosting on the evaporimeter of refrigerating chamber, therefore, wind cooling refrigerator under the refrigeration mode operation a period of time after, need the control wind cooling refrigerator to withdraw from refrigeration mode and enter the defrost pattern, thereby the evaporimeter in the refrigerating chamber is carried out defrost.
In one embodiment of the invention, judge that whether wind cooling refrigerator meets the defrost condition, further comprises:
1) judges whether wind cooling refrigerator accumulative total cooling time under refrigeration mode reaches the 3rd Preset Time.
2) if reach the 3rd Preset Time, judge that then wind cooling refrigerator meets the defrost condition.That is to say, when wind cooling refrigerator moves under refrigeration mode, in the each start-up course of compressor, the start-up time of equal recording compressed machine, and accumulative total will be in one's power start-up time, after the accumulative total start-up time of judging compressor, (namely adding up cooling time) reached the 3rd Preset Time, judge that the frosting on the evaporimeter is more serious, need carry out defrost.As a concrete example, the 3rd Preset Time is but was not limited to 72 hours.
Step S102: if meet the defrost condition, then control the compressor shutdown of wind cooling refrigerator, and continue to close behind freezing fan operation first Preset Time of control.
For example after judging that compressor accumulated running time reaches 72 hours, the control compressor stops refrigeration, and continues to stop behind freezing fan operation first Preset Time of control, wherein, first Preset Time for example for but be not limited to 10 minutes.Like this, freezing blower fan works independently, and evaporimeter can pass through further heat exchange in the process, with cold take to wind cooling refrigerator between in the chamber (as refrigerating chamber and/or refrigerating chamber and refrigerating chamber), thereby make wind cooling refrigerator between indoor temperature further reduce and reduce the energy consumption of refrigeration, the frost layer on colleague's evaporimeter also can partly melt.
Step S103: after freezing blower fan cut out second Preset Time, the control wind cooling refrigerator entered the defrost pattern to carry out defrost.
In one embodiment of the invention, second Preset Time is but was not limited to 5 minutes.That is to say that freezing blower fan cuts out after 10 minutes in isolated operation, and after closing 5 minutes, the control wind cooling refrigerator carries out defrost (as to being positioned at the evaporimeter defrost of refrigerating chamber).As from the foregoing, in step S102, indoor temperature has not only been saved the required energy consumption of freezing between wind cooling refrigerator after further reducing, and the white layer segment on the evaporimeter is melted.Like this, in step S103, when as defrosting heater evaporimeter being carried out defrost, not only save the defrost time, save the required energy consumption of defrost, avoided simultaneously wind cooling refrigerator between the ascensional range of indoor temperature excessive, like this, after refrigerator withdraws from the defrost pattern, avoided wind cooling refrigerator between indoor temperature too high, thereby be conducive to reduce cooling time, save energy consumption, avoid a fluctuations in indoor temperature to cause storing food spoilage more greatly simultaneously, be conducive to the food preservation longer time.
For example: after the control wind cooling refrigerator enters the defrost pattern and carries out defrost, also comprise: when judging that continuing the defrost time reaches the 4th Preset Time, perhaps, indoor temperature rises 2 degrees centigrade the time between wind cooling refrigerator, and the control wind cooling refrigerator withdraws from the defrost pattern and goes to refrigeration mode.Wherein, the 4th Preset Time is determined by empirical value, for example about 10 minutes.And by above-mentioned steps S102 and S103 as can be known, because in process of refrigerastion, the frost layer on the evaporimeter part melts, therefore, the 4th Preset Time is less than the existing defrost time.Because the defrost time is shorter, therefore, the above-mentioned amplitude of an indoor temperature is less, has saved the energy consumption of wind cooling refrigerator.
According to the control method of the wind cooling refrigerator of the embodiment of the invention, the control compressor quits work before defrost, and freezing blower fan (being evaporation fan) was worked independently as 5～20 minutes, enters defrost at last.Evaporimeter can pass through further heat exchange in freezing blower fan works independently process, and cold is taken in the refrigerator body, indoor temperature between the reduction defrost is preceding.Frost layer on the evaporimeter also can partly melt simultaneously, in defrost process, can shorten the defrost time, the shortening of defrost time not only reduced the electric energy that defrost consumes but also reduce between indoor temperature rise amplitude, reach and not only avoided a fluctuations in indoor temperature to cause food spoilage greatly but also saved energy consumption (energy consumption that the energy consumption that defrost consumes and refrigeration consume all can be saved).Particularly, reduce the amplitude that the middle indoor temperature of defrost process raises, for example can make an indoor temperature change generated in case in 2 ℃, guarantee the refrigerating effect of food, can shorten the defrost time again, and can after defrost, consume a small amount of bar will between indoor temperature drop to design temperature fast, energy-saving effect can reach more than 3%.

In one embodiment of the invention, master controller 240 judges that whether wind cooling refrigerator meets the defrost condition, further comprises:
1) judges whether wind cooling refrigerator accumulative total cooling time under refrigeration mode reaches the 3rd Preset Time.
2) if reach the 3rd Preset Time, judge that then wind cooling refrigerator meets the defrost condition.That is to say, when wind cooling refrigerator moves under refrigeration mode, in compressor 231 each start-up courses, the start-up time of equal recording compressed machine, and accumulative total will be in one's power start-up time, after the accumulative total start-up time of judging compressor 231, (namely adding up cooling time) reached the 3rd Preset Time, judge that the frosting on the evaporimeter 222 is more serious, need carry out defrost.As a concrete example, the 3rd Preset Time is but was not limited to 72 hours.
Then, after judging that 231 accumulated running times of compressor reach 72 hours, control compressor 231 stops refrigeration, and continues to stop behind freezing blower fan 211 operations of control first Preset Time, wherein, first Preset Time for example for but be not limited to 10 minutes.Like this, freezing blower fan 211 works independently, and evaporimeter 222 can pass through further heat exchange in the process, with cold take to wind cooling refrigerator between in the chamber (as refrigerating chamber and/or refrigerating chamber and refrigerating chamber), thereby make wind cooling refrigerator between indoor temperature further reduce and reduce the energy consumption of refrigeration, the frost layer on colleague's evaporimeter 222 also can partly melt.
In one embodiment of the invention, above-mentioned second Preset Time for but be not limited to 5 minutes.That is to say that freezing blower fan 211 cuts out after 10 minutes in isolated operation, and after closing 5 minutes, the control wind cooling refrigerator carries out defrost (as to being positioned at the evaporimeter defrost of refrigerating chamber).As from the foregoing, indoor temperature has not only been saved the required energy consumption of freezing between wind cooling refrigerator after further reducing, and the white layer segment on the evaporimeter 222 is melted.Like this, when carrying out defrost as 221 pairs of evaporimeters of defrosting heater 222, not only save the defrost time, save the required energy consumption of defrost, avoided simultaneously wind cooling refrigerator between the ascensional range of indoor temperature excessive, like this, after refrigerator withdraws from the defrost pattern, avoided wind cooling refrigerator between indoor temperature too high, thereby be conducive to reduce cooling time, save energy consumption, avoid a fluctuations in indoor temperature to cause storing food spoilage more greatly simultaneously, be conducive to the food preservation longer time.
