Summary of the invention
The present invention provides a kind of wind cooling refrigerator defrosting control method, and wind cooling refrigerator defrosting program is carried out assisting control by controlling refrigerator inside environment temperature, is effectively increased the refrigeration of refrigerator by it.
In order to solve above-mentioned technical problem, the technical scheme that the present invention provides is, a kind of wind cooling refrigerator defrosting control method, it includes conventional control methods, and this conventional control methods is the temperature of detection evaporimeter, when the temperature of evaporimeter reaches setting value, starting defrost timing routine, timing arrives, and starts defrosting program, also include following auxiliary control method
The first step, it is judged that whether refrigerating-chamber door closes, if it has not, then temperature of refrigerating chamber monitoring programme initializes, if turned off, then judge whether refrigerator starts to refrigeration chamber, and perform second step；
Second step, without starting refrigeration, does not the most start temperature of refrigerating chamber monitoring programme, if starting refrigeration, then starts temperature of refrigerating chamber monitoring programme, and judges whether temperature rises, and perform the 3rd step；
3rd step, if temperature does not rise, does not the most start refrigerating chamber air channel defrosting program；If temperature rises, it may be judged whether persistently rise more than 2 minutes, and perform the 4th step；
4th step, if temperature the most persistently rises more than 2 minutes, does not the most start refrigerating chamber air channel defrosting program, if constant temperature rises more than 2 minutes, then starts refrigerating chamber air channel defrosting program, and performs the 5th step；
5th step, after the defrosting EP (end of program) of refrigerating chamber air channel, temperature of refrigerating chamber monitoring programme initializes, and re-starts monitoring；
Compared to the prior art, this programme is to be monitored temperature of refrigerating chamber, mainly avoid the serious frosting in refrigerating chamber air channel, and by the Logic judgment to refrigerating chamber door body opening and closing, it is to avoid the refrigerating-chamber door opening and closing impact on temp. in refrigerating chamber, the most not temperature of refrigerating chamber one gos up, just is defrosted in refrigerating chamber air channel at once, but need refrigerating chamber environment temperature the most persistently to go up, reduce the possibility of erroneous judgement so further, optimize refrigerating chamber air channel defrosting effect.
Also include following auxiliary control method,
The first step, it is judged that whether refrigerating chamber door closes, if it has not, the most do not start freezer temperature monitoring programme, if refrigerating chamber door is closed, then judges whether freezer temperature reaches less than-13 DEG C, and performs second step；
Second step, if not reaching less than-13 DEG C, does not the most start freezer temperature monitoring programme, if reaching less than-13 DEG C, then starts freezer temperature monitoring programme, and judges whether freezer temperature gos up, and perform the 3rd step；
3rd step, if not ging up, the most not starting evaporimeter defrosting program, if gone up, then judging whether persistently to go up to more than-12 DEG C, and perform the 4th step；
4th step, without persistently ging up to more than-12 DEG C, does not the most start evaporimeter defrosting program, if persistently gone up to more than-12 DEG C, then starts evaporimeter defrosting program, and performs the 5th step；
5th step, after defrosting program completes, re-starts monitoring；
This programme is to be monitored freezer temperature, mainly avoid the serious frosting of evaporimeter, because evaporimeter is positioned at refrigerating chamber, refrigerating chamber is directly freezed by it, if evaporimeter frosting is serious, the temperature meeting rebound significantly of refrigerating chamber, by freezer environment temperature is monitored, can effectively realize the auxiliary to evaporimeter defrost to control, because putting into food in refrigerating chamber freezer temperature can be produced considerable influence, its temperature meeting rebound significantly, so when freezer environment temperature is monitored, the control of the auxiliary to evaporimeter defrost is realized by monitoring several temperature segment values.
In described freezer evaporator Defrost method, when temperature reaches-16～-14 DEG C, then start freezer temperature monitoring programme；
The segment value starting freezer temperature monitoring programme is set as-16～-14 DEG C by this programme, fully takes into account refrigerating chamber normal conditions, and temperature should be less than-18 DEG C, if just starting monitoring programme more than-14 DEG C, having little significance, and easily judging by accident.
In the Defrost method of described refrigerating chamber air channel, when constant temperature rises 3～5 minutes, start refrigerating chamber defrosting program；
When the constant temperature rise time in the defrosting of refrigerating chamber air channel is set as 3～5 minutes by this programme, it is contemplated that the time is the shortest, and False Rate is higher, and the time is longer, can affect again refrigeration chamber, so controlling is that comparison is rational within the above-mentioned time period.
In described freezer evaporator Defrost method, when temperature recovery to-11～-10 DEG C, then start evaporimeter defrosting program；
Under this programme normally freezes in view of freezer temperature, because picking and placeing food etc., its range of temperature is bigger, so being started the temperature recovery point control of evaporimeter defrosting program more than-11 DEG C, can effectively reduce erroneous judgement probability, certainly, if controlled by rise temperature spot is too high, influence whether refrigerating chamber refrigeration, had better not be higher than-10 DEG C.

Detailed description of the invention
Embodiment one:
Described in the present embodiment, wind cooling refrigerator defrosting control method includes conventional control methods and auxiliary control method, wherein, conventional control methods is some the most general control methods, one of which conventional control methods is briefly enumerated at this, such as: the temperature of detection evaporimeter, when the temperature of evaporimeter reaches setting value, defrost timing routine is started, timing arrives, and starts defrosting program.Auxiliary control method is to cooperate with conventional control methods and improves defrosting function further, solves some technical problems present in conventional control methods.nullThis auxiliary control method is specifically: as shown in Figure 1，First，Judge whether refrigerating-chamber door closes，Because it is different that refrigerating-chamber door opens or closes the influent factor to temp. in refrigerating chamber，When open，Temp. in refrigerating chamber can be impacted by ambient temperature，This is that auxiliary control method can not be normally carried out，The most when the cooling chamber door is closed，The rise that just can ensure that temp. in refrigerating chamber is caused by the impact in refrigerating chamber air channel，So its decision logic is: without closedown，Then temperature of refrigerating chamber monitoring programme initializes，If turned off，Then judge whether refrigerator starts to refrigeration chamber，After determining that refrigerating chamber door body is closed，Need to judge whether refrigerator starts to refrigeration chamber，Because if refrigeration chamber do not given by refrigerator，Then temperature of refrigerating chamber is likely to，In fact，The not serious frosting in refrigerating chamber air channel，Its decision logic is: without starting refrigeration，The most do not start temperature of refrigerating chamber monitoring programme，If starting refrigeration，Then start temperature of refrigerating chamber monitoring programme，And judge whether temperature rises，When determining that refrigerator is to refrigeration chamber，Next need to judge whether temperature of refrigerating chamber rises，Only temperature rising just has is the serious frosting in refrigerating chamber air channel，Its decision logic is: if temperature does not rise，The most do not start refrigerating chamber air channel defrosting program；If temperature rises, judge whether persistently to rise 2 minutes, temperature rises it could also be possible that refrigeration system itself runs the rise the most freely causing transience, so needing to judge whether temperature can persistently rise, this can select often is 2 minutes, and it is difficult to oversize, impact refrigeration, being not easy to the shortest, erroneous judgement probability increases；If temperature the most persistently rises 2 minutes, the most do not start refrigerating chamber air channel defrosting program, if constant temperature rises 2 minutes, then start refrigerating chamber air channel defrosting program；After the defrosting EP (end of program) of refrigerating chamber air channel, temperature of refrigerating chamber monitoring programme initializes, and re-starts monitoring, if in defrosting program is carried out, opening refrigerating-chamber door, then defrosting program proceeds, until completing defrosting, reinitializing and being monitored.
nullAs improvement，Auxiliary control method also includes freezer evaporator defrosting control，Similar with refrigerating chamber，It first determines whether whether refrigerating chamber door closes，Without closedown，The most do not start freezer temperature monitoring programme，If refrigerating chamber door is closed，Then judge whether freezer temperature reaches-13 DEG C，Because under normal circumstances，The temperature of refrigerating chamber to reach less than-18 DEG C，So its temperature can cause amplitude of variation bigger because of access food，If not reaching-13 DEG C，The most do not start freezer temperature monitoring programme，If reaching-13 DEG C，Then start freezer temperature monitoring programme，And judge whether freezer temperature gos up，If do not gone up，The most do not start evaporimeter defrosting program，If gone up，Then judge whether persistently to go up to-10 DEG C，Without persistently ging up to-10 DEG C，The most do not start evaporimeter defrosting program，If persistently gone up to-10 DEG C，Then start evaporimeter defrosting program，After defrosting program completes，Re-start monitoring.
Embodiment two:
The present embodiment is compared with embodiment one, and its difference is, in the Defrost method of refrigerating chamber air channel, constant temperature rises 3 minutes；In freezer evaporator Defrost method, if refrigerating chamber door is closed, whether freezer temperature reaches-16 DEG C, if not reaching-16 DEG C, the most do not start freezer temperature monitoring programme, if reaching-16 DEG C, then start freezer temperature monitoring programme, and judge whether freezer temperature gos up, if do not gone up, the most not starting evaporimeter defrosting program, if gone up, then judging whether persistently to go up to-12 DEG C, without persistently ging up to-12 DEG C, the most not starting evaporimeter defrosting program, if persistently gone up to-12 DEG C, then starting evaporimeter defrosting program.
Embodiment three:
The present embodiment is compared with embodiment one, two, and its difference is, in the Defrost method of refrigerating chamber air channel, constant temperature rises 5 minutes；In freezer evaporator Defrost method, if refrigerating chamber door is closed, whether freezer temperature reaches-14 DEG C, if not reaching-14 DEG C, the most do not start freezer temperature monitoring programme, if reaching-14 DEG C, then start freezer temperature monitoring programme, and judge whether freezer temperature gos up, if do not gone up, the most not starting evaporimeter defrosting program, if gone up, then judging whether persistently to go up to-11 DEG C, without persistently ging up to-11 DEG C, the most not starting evaporimeter defrosting program, if persistently gone up to-11 DEG C, then starting evaporimeter defrosting program.
Be respectively provided with temperature sensor in above-mentioned refrigerating chamber, refrigerating chamber, temperature be monitored, on refrigerating chamber air channel and evaporimeter on defroster is set, they are all controlled by refrigerator control module, it is achieved said method.
