The invention discloses a kind of air blowing control methods of cold compartment of refrigerator, for carrying out to the indoor air supply process of refrigeration
Logic control prevents from occurring in refrigerating chamber refrigerated storage temperature of the local temperature higher than default (in the prior art, when cold to realize
The temperature that the temperature sensor of hiding room detects just blows to refrigerating chamber when being greater than refrigerated storage temperature, so that refrigerating chamber is long-term
It is maintained at refrigerated storage temperature or less) the problem of.There is the independent sealed space for accommodating dry goods, dry goods are concentrated in refrigerating chamber
It deposits in this independent sealed space.
As shown in Figure 1, air blowing control method includes:
S101: the trigger signal blown to independent sealed space is obtained；
S103: after determining trigger signal, starting refrigerator damper is blown to independent sealed space；
S105: the indoor whole storing temperature of refrigeration is obtained in air supply process and timing is carried out to air supply time；
S107: after whole storing temperature and/or air supply time meet setting halt condition, stop to independent sealed space
Air-supply.
In above-mentioned steps S101, trigger signal can be the temperature value of the temperature sensor senses in refrigerating chamber to refrigerating chamber
Lower than preset refrigeration value.Preferably, above-mentioned trigger signal can move to closing shape by opening state for the chamber door of refrigerating chamber
The shutdown signal of state.When the sensing device of refrigerator senses that refrigerator is closed, system default user is put in independent sealed space
Into article, although refrigerating indoor temperature sensor senses less than the raised signal of temperature in independent sealed space, this
When system by sensing chamber door, by open movement, to defaulting in independent sealed space and closing, local temperature occur excessively high
Phenomenon.After determining trigger signal, refrigerator damper supply cold wind into independent sealed space is opened, is supplied in independent sealed space
While cold wind, timer carries out timing to the time of air feed.When the whole storing temperature and/or air supply time of refrigerating chamber meet
After setting halt condition, stop blowing to independent sealed space, default at this time temperature in independent sealed space already below
Preset temperature.
In above-described embodiment, the device whether induction refrigerating chamber chamber door closes is the device that refrigerator carries, therefore above-mentioned control
Without increasing any element in method, prevent occurring part temperature in independent sealed space using logic control merely to realize
Spend high problem.This is risen compared to production is reduced for the scheme for increasing temperature sensor.
It is provided in refrigerating chamber and limits the dry drawer in independent sealed space, i.e., dry goods are left concentratedly takes out in dry
In drawer, the dry drawer detection device that whether its closes with independent detection, detection device is mechanical switch or magnetic mechanism.
After the chamber door for switching refrigerating chamber due to user, article is not necessarily put into dry drawer, therefore when system senses that chamber door is closed
Waste electric power can be haveed the defects that by carrying out air-supply into dry drawer immediately afterwards, in order to solve drawbacks described above, in a kind of embodiment,
Above-mentioned trigger signal can also be moved to the shutdown signal of closed state for dry drawer by opening state, i.e., dry drawer
When sensing device senses that dry drawer moves to closed state by opening state, default user is put into independent sealed space
Article, although refrigerate indoor temperature sensor senses less than the raised signal of temperature in independent sealed space, at this time
Local temperature in the independent sealed space of system default is excessively high.After determining trigger signal, it is close to independence to open refrigerator damper
Supply cold wind in space is sealed, in independent sealed space while supply cold wind, timer carries out timing to the time of air feed.Work as refrigeration
After the whole storing temperature and/or air supply time of room meet setting halt condition, stops blowing to independent sealed space, write from memory at this time
The temperature in independent sealed space is recognized already below preset temperature.
A possibility that being put into dry goods into dry drawer when opening dry drawer due to user is very big, by trigger signal
The accuracy that system judgement can be enhanced by the shutdown signal that the shutdown signal of chamber door is changed to dry drawer, reduces dry pumping
Still to the number that it is blown when temperature in drawer is lower than refrigerated storage temperature, power cost has been saved.Also, when dry drawer is opened
Afterwards, extraneous vapor condensation will form droplet in dry drawer, so that the dry goods dampness in dry drawer, Gu Danggan
After dry drawer is closed, preferable drying function can be played by carrying out air-supply into dry drawer immediately.
While due to blowing into independent sealed space, cold wind will also be delivered to other positions of refrigerating chamber, therefore hold
Continue and blow after a certain period of time into the higher independent sealed space of local temperature, there are certainly possible other positions for making refrigerating chamber

Only blow to refrigerating chamber.
Due to refrigerating chamber temperature sensor measurement there are deviation, the whole storage of can completely expression refrigerating chamber
Object temperature, and occur in refrigerating chamber local temperature it is too low when, will not occur freezing on a large scale, thus when refrigerating chamber temperature pass
The temperature that sensor detects out-of-blast operating process of just pulling up a horse lower than the first temperature threshold is overly conservative.A kind of embodiment
In, halt condition can also include the whole storing temperature of refrigerating chamber less than or equal to the first temperature threshold and when persistently presetting
It is long；To prevent refrigerating chamber from freezing.I.e. when the temperature that the temperature sensor of refrigerating chamber detects is lower than the first temperature threshold, not
Have it is out-of-blast immediately, but continue preset duration after it is out-of-blast again.Preset duration is according to refrigerator power or refrigerating chamber
The difference of space size can suitably change.
Due to the particular surroundings in refrigerator, it may appear that be down to zero at a temperature of moisture it is following after the supercooling that does not still freeze
Phenomenon, therefore the optimal value of the first temperature threshold not necessarily zero degrees celsius, but in the above-described embodiments, due to when refrigerating chamber
After the temperature that temperature sensor detects is lower than the first temperature threshold, certain time is out-of-blast again, therefore in above-mentioned implementation
