Judge whether evaporator 340 needs defrost；Specifically, the wind cooling refrigerator 10 in the present embodiment enters defrost pattern packet
Include to automatically select and be manually selected with user, wherein automatically select be can be according to wind cooling refrigerator 10 cumulative operation time and evaporation
The cumulative operation time of device 340 is judged, and wind cooling refrigerator can be controlled at any time according to user's self-demand by manually selecting
10 enter defrost pattern；
If so, closing the second air door 410；
The temperature of freezing chamber 200 and refrigerating chamber 100 is detected, and when the temperature of freezing chamber 200 is less than first threshold temperature,
It controls evaporator 340 and stops refrigeration；
If specifically, the temperature of freezing chamber 200 be higher than first threshold temperature, open the first air door 610 to freezing chamber 200 into
Row refrigeration, while whether the temperature for detecting refrigerating chamber 100 is more than third threshold temperature, if so, opening the second air door 410 to refrigeration
Room 100 is freezed, and is less than or equal to third threshold temperature in the temperature of refrigerating chamber 100 and is greater than or equal to the 4th threshold temperature
When close the second air door 410, can be refrigerated in effective refrigerating temperature range with the storing ensured in refrigerating chamber 100.
It closes the first air door 610, opens the second air door 410, the work of control wind turbine 330 is with will be in evaporator chamber 300
Air is blowed through refrigerating air duct 400 to refrigerating chamber 100, so make the return air generated in refrigerating chamber 100 from return airway 500 into
Enter in evaporator chamber 300；Since evaporator 340 stopped refrigeration work, the return air temperature generated in refrigerating chamber 100 gos up,
It is arranged again close to the second air inlet 310 due to heating tube 350, so being entered in evaporator chamber 300 by the second air inlet 310
High temperature return air is persistently preheated to heating tube 350；
The temperature for detecting refrigerating chamber 100 closes the second air door when the temperature of refrigerating chamber 100 reaches second threshold temperature
410, wherein second threshold temperature is more than third threshold temperature, to retain appropriate space for the heating of refrigerating chamber 100, to ensure
High temperature return air is sufficient to the preheating of heating tube 350, while the highest refrigerated storage temperature that second threshold temperature is refrigerating chamber 100, if cold
It hides and still maintains the unlatching of the second air door 410 when temperature is higher than second threshold temperature in room 100, temperature in refrigerating chamber 100 can be caused
The lasting effective refrigeration increased and then influence storing in refrigerating chamber 100；
It controls heating tube 350 to start to work, until 340 defrost of evaporator is completed.Since heating tube 350 is persistently by high temperature
The preheating of return air enables heating tube 350 to be heated to the required temperature of defrost within the shorter time, saves heating tube 350
Energy expenditure when heated, is more energy-saving and environmentally friendly.
Defrosting method proposed by the present invention, by the way that the high temperature return air in refrigerating chamber 100 is back to steaming through return airway 500
Heating tube 350 is preheated in hair device chamber 300, heating tube 350 is enable to be heated to defrost temperature within the shorter time, is saved
The energy expenditure of heating tube 350 when heated has been saved, has been more energy-saving and environmentally friendly.
