Accompanying drawing explanation
Fig. 1 is the flow chart of refrigerator self adaptation defrosting control method one embodiment of the present invention;
Fig. 2 is the flow chart of another embodiment of refrigerator self adaptation defrosting control method of the present invention.
Detailed description of the invention
Describe the present invention below with reference to detailed description of the invention shown in the drawings.But these embodiments do not limit the present invention, the structure that those of ordinary skill in the art makes according to these embodiments, method or conversion functionally are all included in protection scope of the present invention.
According to one embodiment of present invention, refrigerator can be air-cooled frost-free refrigerator, comprises casing, Men Ti, air channel, blower fan, evaporimeter, compensating heating device, temperature sensor, timer and controller.
Casing comprises refrigerating chamber and refrigerating chamber.
Door body is pivotably mounted on casing to open or close refrigerating chamber and refrigerating chamber.
Air channel to be located in casing and to have the first wind passage mouth be communicated with refrigerating chamber and the second wind passage mouth be communicated with refrigerating chamber.Blower fan is located in air channel, and the cold air for being produced by evaporimeter sends into corresponding room.
Compensating heating device is arranged in casing, for pair between room heat up.Preferably, compensating heating device is for compensating heater strip.
Timer is at least one, jt interval time of monitoring refrigerator defrost, accumulative opening time kt in defrost gap periods, and refrigerator defrost time ht.Particularly, jt refers to the time terminating to timer time from previous defrost; Kt refers to the accumulative opening time terminating to timer time from previous defrost; Ht refers to that in a defrost periods, defrost starts to the time of end.
Preset maximum defrost T interval time of refrigerator max, minimum defrost T interval time min, preset accumulative opening time kT 1with desirable defrost time hT.Described preset value is constant, embeds in controller by program.Preset value is determined by the method for experiment, and when the model of refrigerator is fixed, corresponding preset value is fixed.
Fig. 1 is the flow chart of refrigerator self adaptation defrosting control method one example of the present invention.The defrosting control of refrigerator comprises:
S1: the jt and the interior accumulative opening time kt of defrost gap periods interval time of timer monitoring refrigerator defrost.
S2: controller compares the jt and maximum defrost T interval time interval time of refrigerator defrost max.If jt>=T max, controller starts defrost.
If jt<T max, then controller compares in the gap periods of current refrigerator defrost, and actual accumulative opening time kt and presetting of this defrost gap periods add up opening time kT i(i is positive integer).
S3: if kt >=kTi, controller starts defrost, otherwise, return step S1.
S4: start defrost, comprise the steps:
Start blower fan and preheating is carried out to evaporimeter;
Controller is started working by temperature-adjusting potentiometer control and compensation heater;
Temperature sensor detection compartment temperature, terminates defrost after reaching default temperature;
Timer monitoring defrost starts the time ht to terminating.
After completing defrost, carry out following steps:
S5: controller compares ht and default defrost time hT.If ht>hT, that shortens next cycle presets accumulative opening time kT i+1, correspondingly, shorten the defrost interval duration in next cycle; If ht<hT, what extend next cycle presets accumulative opening time kT i+1, correspondingly, extend the defrost interval duration in next cycle; If ht=hT, what maintain next cycle presets accumulative opening time kT i+1opening time kT is added up with presetting of this cycle iunanimously, correspondingly, the defrost interval duration in next cycle is maintained.Particularly, kT i+1=kT i+ a(hT-ht), a is constant, and this constant is positive number and relevant to refrigerator volume, environment temperature etc.
Meanwhile, refrigerator enters next defrost gap periods, repeats step S1.
Wherein, in step S3, for preventing the frequent defrost of refrigerator, jt and minimum defrost T interval time can also be compared min.If kt>=kTi and jt>T min, enter step 4, otherwise, return step S1.
Be understandable that, add up opening time kT presetting of a defrost gap periods iin, i represents this cycle.Before refrigerator energising runs, kT 1be embedded in control program.First defrost periods is with this fixed value kT 1for presetting accumulative opening time, and method according to the present invention determines that presetting of next cycle adds up opening time kT after defrost terminates 2, so circulate.
With reference to figure 2, in the another example of the present invention, the defrosting control of refrigerator comprises:
S1 ', the reality of monitoring current defrost gap periods add up opening time kt;
The reality of S2 ', more current defrost gap periods adds up opening time kt and presetting of current defrost gap periods adds up opening time kT iif actual accumulative opening time is more than or equal to described presetting and adds up opening time kT i, enter step S3 ', otherwise, return step S1 ';
S3 ', start defrost, and monitor defrost start to terminate time ht;
After S4 ', defrost terminate, compare ht and defrost time preset value hT, add up opening time kT to obtain presetting of next defrost gap periods i+1.
KT i+1the same previous embodiment of computational methods.
Further, also monitor jt interval time of defrost, and between step S1 ' and S2 ', compare the jt and maximum defrost preset value interval time T interval time of defrost max, minimum defrost preset value interval time T min.If T min<jt<T max, perform described step S2 ', otherwise, compare jt and whether be more than or equal to T max.If so, then directly step S3 ' is entered, otherwise, mean jt<T min, then step S1 ' is returned.
This embodiment and difference embodiment illustrated in fig. 1 are the order of determining step.
So, can according to the defrost duration of each defrost periods, adjust the duration of next defrost gap periods, more specifically, adjust the accumulative enabling duration of next defrost periods, thus making the practical operation situation of defrost frequency adaptation in user of refrigerator, defrosting control is more accurate and intelligent, reaches energy-conservation, fresh-keeping effect.
Be to be understood that, although this description is described according to embodiment, but not each embodiment only comprises an independently technical scheme, this narrating mode of description is only for clarity sake, those skilled in the art should by description integrally, technical scheme in each embodiment also through appropriately combined, can form other embodiments that it will be appreciated by those skilled in the art that.
A series of detailed description listed is above only illustrating for feasibility embodiment of the present invention; they are also not used to limit the scope of the invention, all do not depart from the skill of the present invention equivalent implementations done of spirit or change all should be included within protection scope of the present invention.
