It is non-to be used to limit the scope of the present invention.
Embodiment 1, a kind of cold compartment of refrigerator defrosting method.With reference to Fig. 1 to defrosting method provided in this embodiment into
Row explanation.
Referring to Fig. 1, cold compartment of refrigerator defrosting method provided in this embodiment includes：
S1, when cold compartment of refrigerator refrigeration system stop refrigeration when, detection freezer compartment of refrigerator whether need defrost, if not
Need, then perform S2, otherwise perform S3.
S2, control refrigeration wind turbine are operated, until the temperature of refrigeration evaporator reaches the first preset temperature, control refrigeration
Wind turbine shuts down, and terminates process flow；
S3, detection refrigerator external environment condition humidity, refrigerate wind turbine according to refrigerator external environment condition humid control and are operated, until
The temperature of refrigeration evaporator reaches the second preset temperature, and control refrigeration wind turbine shuts down.
Specifically, refrigerator, during normal work, refrigerating chamber is intermittent work, reached not when refrigerating indoor temperature
Freeze to indoor refrigeration system when requiring, is refrigerated；After by process of refrigerastion, when the temperature of refrigerating chamber reaches requirement,
Refrigerate indoor refrigeration system and stop refrigeration, at this time, refrigerating chamber needs to carry out defrost processing.Usually existing defrost processing
It is that heater is installed in itself in refrigeration evaporator bottom meeting evaporator, plays the role of defrost, heater needs during defrost
Electric energy is consumed, therefore the defrost scheme that the present embodiment proposes but is realized cold without heater by refrigerating the operating of wind turbine
Hide the defrost on evaporator.
The present embodiment is during specific defrost, and when the refrigeration system of cold compartment of refrigerator stops refrigeration, detection refrigerator is cold
Freeze whether room needs defrost, the situation of defrost whether is needed according to freezer compartment of refrigerator, takes different defrost schemes to refrigerating chamber
Carry out defrost.
Wherein, if defrost is not required in freezer compartment of refrigerator, control refrigeration wind turbine is operated, until the temperature of refrigeration evaporator
Reach the first preset temperature, control refrigeration wind turbine shuts down, to be realized by refrigerating the operating of wind turbine on refrigeration evaporator
Defrost.If freezer compartment of refrigerator needs defrost, refrigerator external environment condition humidity is detected, according to refrigerator external environment condition humidity, control
Refrigeration wind turbine is operated, and until the temperature of refrigeration evaporator reaches the second preset temperature, control refrigeration wind turbine shuts down, with
The defrost on refrigeration evaporator is realized by refrigerating the operating of wind turbine.
Wherein, above-mentioned steps S3 is specially：
Refrigerator external environment condition humidity range, is divided into multiple humidity sections by S31, and different humidity sections corresponds to defrost
Refrigeration evaporator needs the second different preset temperatures reached in journey；
S32, judge humidity section belonging to current refrigerator external environment condition humidity, and controls refrigeration wind turbine operating, Zhi Daoleng
The temperature for hiding evaporator reaches the second preset temperature corresponding with the humidity section, and control refrigeration wind turbine shuts down, to pass through
The defrost on refrigeration evaporator is realized in the operating of refrigeration wind turbine.
The second above-mentioned preset temperature is according to the humidity of refrigerator external environment condition humidity on the basis of the first preset temperature
Section increases corresponding preset value adjustment, wherein, the humidity section has correspondence with preset value, and usual first is default
Temperature is 5 degrees Celsius.
In the present embodiment, current refrigerator external environment condition humidity is divided into humidity section as 3, is respectively the first humidity
Section, the second humidity section and the 3rd humidity section；
When the humidity section belonging to refrigerator external environment condition humidity is the first humidity section, then in first preset temperature
On the basis of increase by the first preset value to reach the second preset temperature；
When the humidity section belonging to refrigerator external environment condition humidity is the second humidity section, then in first preset temperature
On the basis of increase by the second preset value, to reach the second preset temperature；
When the humidity section belonging to refrigerator external environment condition humidity is the 3rd humidity section, then in first preset temperature
On the basis of increase by the 3rd preset value to reach the second preset temperature.
After the second preset temperature is determined, control refrigeration wind turbine operating, until the temperature of refrigeration evaporator, to reach second pre-
If temperature, control refrigeration wind turbine shuts down, and the defrost process of cold compartment of refrigerator is realized by refrigerating the operating of wind turbine.
The present embodiment is by stopping intermittent phase of refrigeration work in refrigerating chamber, by refrigerating chamber fan positive opening, by cold
Indoor cross-ventilation is hidden, the frost on refrigeration evaporator is melted, when the temperature of refrigeration evaporator reaches requirement, stops refrigeration
The operating of wind turbine, defrost process terminate.

When indoor refrigeration system stops refrigeration, whether detection refrigerating chamber needs defrost, if defrost is not required in refrigerating chamber, carries out nature
Defrost, i.e. control refrigeration wind turbine operating, until the temperature of refrigeration evaporator reaches 5 degrees Celsius, the operating of stopping refrigeration wind turbine, changes
White process terminates.Wherein, the present embodiment sets defrosting sensor on refrigeration evaporator, specially detects the temperature of refrigeration evaporator
Degree.
When refrigerating chamber needs defrost, it is wet that refrigerator external environment condition is detected by the humidity sensor being arranged on refrigerator door
Spend, when the current environment humidity outside refrigerator is between 75%-85%, control refrigeration wind turbine operating, until refrigeration evaporator
Temperature when reaching 6 degrees Celsius (i.e. on the basis of original 5 degrees Celsius increase by 1 degree Celsius), stop the operating of refrigeration wind turbine, by
Bigger in external environment condition humidity at this time, when refrigerating wind turbine operating, temperature during refrigeration evaporator defrost compares external environment condition
Temperature when humidity is smaller needed for defrost can be higher, i.e., when the temperature of refrigeration evaporator reaches 6 degrees Celsius at this time, that is, completes cold
Hide the defrost process of room；When current environment humidity outside refrigerator is more than 85%, control refrigeration wind turbine operating, until refrigeration is steamed
When the temperature of hair device reaches 7 degrees Celsius (increasing by 2 degrees Celsius on the basis of original 5 degrees Celsius), stop the fortune of refrigeration wind turbine
Turn, complete the defrost process of refrigerating chamber；When current environment humidity outside refrigerator is less than 75%, control refrigeration wind turbine operating,
When the temperature of refrigeration evaporator reaches 5 degrees Celsius (i.e. constant on the basis of original 5 degrees Celsius), stop refrigeration wind turbine
Operating, can be without considering refrigerator external environment condition humidity since refrigerator external environment condition humidity is smaller at this time.
