Control signal is to elements such as compressor 3, evaporator 4, fan 5, heaters, so as to realize the refrigeration and evaporator of control refrigerating chamber
4 defrost.
Under normal circumstances, refrigerator has certain defrost interval time between startup performs former and later two defrost programs,
Shortcomings be present to start defrost program due to setting fixed defrost interval time in the prior art, such as can not enter in time
Row defrosting operation and influence the refrigeration performance of refrigerator or continually carry out defrosting operation and waste energy consumption etc., it is therefore necessary to according to ice
The actual motion and service condition of case carry out adjustment to defrost interval time, to determine an accurate defrost interval time
The corresponding defrost program of deactivation.On the other hand, as shown in Fig. 2 the present invention proposes a kind of refrigerator defrosting control logic of optimization, tool
Body mainly includes following several stages：
Firstth, initial defrost interval time is preset：
After i.e. last defrost EP (end of program), determined based on the refrigerator operation conditions before last defrost EP (end of program)
Start the initial defrost interval time of defrost program next time；
Secondth, initial defrost interval time is corrected：
Corrected based on the refrigerator operation after last defrost EP (end of program) and behaviour in service between the initial defrost
Every the time, to obtain revised actual defrost interval time；
3rd, defrost program next time is started based on actual defrost interval time：
Whether the elapsed time i.e. after the defrost EP (end of program) of judging distance last time has reached revised real-time defrost
Interval time, if the elapsed time after last defrost EP (end of program) has reached revised real-time defrost
Between, then start defrost program next time.
So-called initial defrost interval time, can be after last defrost EP (end of program) to start next time defrost program it
Between refrigerator energization run time and or refrigerator compartment 2 accumulative cooling time.When refrigerator energization run time or refrigerator compartment
When any one time value in 2 accumulation cooling time reaches initial defrost interval time, defrost program next time can be started.
First, the stage of initial defrost interval time is being preset：After last defrost EP (end of program), control device of refrigerator
Can according to before last defrost EP (end of program) (specifically include in last actual defrost interval time with last defrost program
The execution stage) refrigerator operation conditions start initial defrost interval time of defrost program next time to preset.The initial defrost
The initial assignment size of time is mainly influenceed by following two refrigerator operation conditions：First, last defrost program performs rank
The length between heater continuous firing in section；Second, the length of last actual defrost interval time.Above-mentioned two refrigerator is transported
When row situation can independently influence the assignment of initial defrost interval time or combine influence initial defrost interval
Between assignment.
In one embodiment, if the working time of heater is longer in last defrost program, control device is accordingly
Judging, evaporimeter frosting degree is larger and also completely frost is not melted even if heater work really long days, correspondingly, control
The initial defrost interval time that device is default to start defrost program next time is shorter so that next time defrost program start as early as possible with
Frost on evaporator 4 is melted completely, so as to ensure the refrigeration performance of refrigerator；, whereas if heated in last defrost program
The working time of device is shorter, and control device judges that the frost on evaporator 4 completely or almost completely melts accordingly, correspondingly, control
The initial defrost interval time that device processed is default to start defrost program next time is longer, prevents that defrost program opens too quickly next time
It is dynamic.So as to avoid continually starting unnecessary defrost program, energy consumption is saved.
In one embodiment, if last actual defrost interval time is longer, control device judges evaporator 4 accordingly
Upper frosting lesser extent, correspondingly, the initial defrost interval time that control device is default to start defrost program next time are also longer,
Start defrost program next time to postpone.
In one embodiment, last heater on time and last actual defrost interval time two are considered
Individual condition is to determine the assignment of initial defrost interval time.Particularly, if last actual defrost interval time is very long, and
The working time of heater is very short in last defrost program, and control device judges frosting degree on evaporator 4 very accordingly
Gently, correspondingly, the control device default initial defrost interval time for starting defrost program next time can more lengthen, with more backwardly
Postpone and start defrost program next time.
In the above-described embodiments, the initial assignment of initial defrost interval time has maximum limitation.If above-mentioned
Under the overlaying influence of different refrigerator operation conditions, initial defrost interval time reaches the default maximum initial gap time, then not
Continue to extend the initial defrost interval time based on the refrigerator operation conditions before last defrost EP (end of program) again.
Secondly, white stage interval time is initialized in amendment：Refrigerator after last defrost EP (end of program) is run with making
Affected how to correct default initial defrost interval time with situation, specifically, in this stage, refrigerator operation and use
Situation is mainly reflected in following two aspect：First, the enabling situation of refrigerator compartment 2；Second, the single of refrigerator compartment 2 persistently freezes
Time.
In one embodiment, during the refrigerator operation after upper once defrost EP (end of program) with use, between refrigerator
Room 2 often opens once Men Junhui and correspondingly corrects initial defrost interval time, because refrigerator compartment 2 one opens the door, damp-heat air can enter
Enter refrigerator compartment 2, increase the refrigeration demand of refrigerator compartment 2, so as to add the frosting degree on evaporator 4, so control dress
Putting based on enabling each time can correspondingly shorten the initialization interval time, with pre-cooling defrost program next time.In ice
In the case that case compartment 2 opens the door repeatedly, time point when being more proximate to last defrost EP (end of program) opens the door, and larger contracts
Short initial defrost interval time, that is to say, that time point when last defrost EP (end of program), initial stage opens the door to evaporation
The frosting degree of the device 4 increased frost amount i.e. on evaporator 4 that has a great influence is larger, and the later stage opens the door frosting degree shadow to evaporator 4
It is smaller to ring smaller frost amount increased i.e. on evaporator 4.
When accumulative opening time it is longer and or accumulative door opening times it is more, control device judges the frosting journey of evaporator 4 accordingly
Degree is bigger, and correspondingly, control device can larger shorten initial defrost interval time, with the defrost next time of pre-cooling earlier
Program, prevent that the frosting of evaporator 4 is excessively serious and influences the refrigeration performance of refrigerator.
In one embodiment, single of the control device based on the refrigerator compartment 2 after last defrost EP (end of program) is held
Continuous cooling time amendment initial defrost interval time.If the single of the refrigerator compartment 2 after last defrost EP (end of program) is held
Continuous cooling time is more than or equal to a default cooling time, such as the single of refrigerator compartment 2 continues cooling time more than or equal to 6
Hour, control device judges that the frosting on evaporator 4 is more accordingly, then correspondingly, initial defrost interval time is shortened.This is pre-
It is the parameter value drawn according to experiment to be equipped with cool time, refers to refrigerator compartment and continues from refrigeration is started to the full frost of evaporator knot
Cooling time.If the single of refrigerator compartment 2, which continues cooling time, is more than or equal to above-mentioned default cooling time, and in the single
Continue refrigerator compartment 2 in cooling time at least to open the door once, control device judges that evaporator 4 is the full frost of complete knot certainly accordingly
, then correspondingly, initial defrost interval time is reduced to default minimum time interval, such as initial defrost interval time quilt
Foreshorten to default 12 hours, and be no longer shortened later.
In any of the above-described embodiment, there is minimum value limitation revised actual defrost interval time.If amendment
Actual defrost interval time afterwards reaches default minimum time interval, such as minimum time interval is arranged to 12 hours, then
Control device is no longer based on refrigerator operation to be continued to correct the actual defrost interval time with behaviour in service, so as to ensure that refrigerator is being transported
There is certain rational defrost cycle in row, be unlikely to too continually to start defrost program.
In one embodiment, the situation of power-off can be encountered in refrigerator running unavoidably.If refrigerator powers off again
Be powered operation, then detects the temperature of evaporator 4 first；If the evaporator temperature measured is more than or equal to the first preset temperature,
Such as now evaporator temperature is more than or equal to 8 degree, control device judges on evaporator 4 not have frosting substantially accordingly, and by ice
Defrost interval time in case control device resets to the original initial defrost interval time for starting defrost program next time, should
When original initial defrost interval time refers to that refrigerator is initially powered up operation for the first time, the initial defrost that is stored in control device
Interval time；It it is, for example, less than 8 degree if the evaporator temperature measured is less than the first preset temperature, control device judges to steam accordingly
When sending out existing frosting on device 4, and the defrost interval time being stored in when powering off in control device of refrigerator being subtracted into default power-off
Between obtained from the time as the initial defrost interval time for starting defrost program next time.The default power-off time is advance
One fixed reference value of setting, such as the default power-off time are set as 2 hours.
In one embodiment, quick-frozen pattern can be started unavoidably in refrigerator running.If refrigerator starts quick-frozen pattern,
First determine whether now whether be less than or equal to a predetermined interval apart from the remaining interval time for starting defrost program next time,
Such as now whether the remaining interval time is less than or equal to 6 hours；If the remaining interval time is less than or equal to 6 hours,
Control device judges that frosting degree is heavier on evaporator 4 accordingly, and controls refrigerator compartment 2 to start before quick-frozen pattern is entered
Defrost program, so as to substantially improve refrigerating efficiency of the refrigerator under quick-frozen pattern.
In refrigerator runs quick-frozen pattern, counted from into quick-frozen pattern, when the lasting cooling time of refrigerator compartment 2 is more than
Or during equal to the first predetermined cooling time, such as the lasting cooling time of refrigerator compartment 2 is more than or equal to 20 hours, control device
Judge that now knot is full white completely on evaporator 4 accordingly, refrigerator is immediately performed defrost program, so as to lift refrigerator in the case where connecing
Remove to continue to run with the refrigerating efficiency of quick-frozen pattern.
And when refrigerator exits quick-frozen pattern, first determine whether the time that now refrigerator compartment 2 has persistently freezed is big
In or equal to second scheduled time, it is greater than or equal to 20 hours, is if exiting this time point of quick-frozen pattern to refrigerator
Only, the time that refrigerator compartment 2 has persistently freezed, then control device judged now evaporator 4 accordingly more than or equal to 20 hours
On the full frost of knot, and control refrigerator to exit and start defrost program after quick-frozen pattern immediately completely.
