Detailed description of the invention
Fig. 1 is the flow chart of adaptive one embodiment of defrosting control method of refrigerator of the present invention；
Fig. 2 is the flow chart of another embodiment of the adaptive defrosting control method of refrigerator of the present invention.
Specific embodiment
Below with reference to specific embodiment shown in the drawings, the present invention will be described in detail.But these embodiments are simultaneously
The present invention is not limited, structure that those skilled in the art are made according to these embodiments, method or functionally
Transformation is included within the scope of protection of the present invention.
According to one embodiment of present invention, refrigerator can be air-cooled frost-free refrigerator, including cabinet, door body, air duct, blower,
Evaporator, compensating heating device, temperature sensor, timer and controller.
Cabinet includes freezing chamber and refrigerating chamber.
Door body is pivotably mounted on cabinet to open or close freezing chamber and refrigerating chamber.
Air duct is located in cabinet and has the first wind passage mouth being connected to freezing chamber and the second air duct being connected to refrigerating chamber
Mouthful.Blower is located in air duct, and the cold air for generating evaporator is sent into corresponding compartment.
Compensating heating device is set in cabinet, for heating up to compartment.Preferably, compensating heating device is compensation heating
Silk.
Timer is at least one, monitors the interval time jt of refrigerator defrost, adds up opening time in defrost gap periods
Kt and refrigerator defrost time ht.Specifically, jt refers to the time terminated from previous defrost to timer time；Kt refers to from previousization
Frost terminates to arrive the accumulative opening time of timer time；Ht refers to that defrost in a defrost period starts to the time of end.
The maximum defrost interval time T of default refrigeratormax, minimum defrost interval time Tmin, default accumulative opening time kT1
With ideal defrost time hT.The preset value is constant, can be embedded in controller by program.Preset value can pass through the side of experiment
Method determines that, when the model of refrigerator is fixed, corresponding preset value is fixed.
Fig. 1 is the exemplary flow chart of the adaptive defrosting control method one of refrigerator of the present invention.The defrosting control of refrigerator includes:
S1: timer, which monitors, adds up opening time kt in the interval time jt and defrost gap periods of refrigerator defrost.
S2: controller compares the interval time jt and maximum defrost interval time T of refrigerator defrostmax.If jt >=Tmax, control
Device processed starts defrost.
If jt < Tmax, then controller compares in the gap periods of current refrigerator defrost, practical accumulative opening time kt
With the default accumulative opening time kT of the defrost gap periodsi(i is positive integer).
S3: if kt >=kTi, controller starts defrost, otherwise, return step S1.
S4: starting defrost includes the following steps:
Starting blower preheats evaporator；
Controller controls compensating heating device by temperature-adjusting potentiometer and starts to work；
Temperature sensor detects compartment temperature, terminates defrost after reaching preset temperature；
The time ht of timer monitoring defrost start and ending.
After completing defrost, following steps are carried out:
S5: controller compares ht and default defrost time hT.If ht > hT, shorten the default accumulative enabling in next period
Time kTi+1, correspondingly, shorten the defrost interval duration in next period；If ht < hT, extend the default accumulative of next period
Opening time kTi+1, correspondingly, extend the defrost interval duration in next period；If ht=hT, the pre- of next period is maintained
If accumulative opening time kTi+1With the default accumulative opening time kT in this periodiUnanimously, correspondingly, the defrost in next period is maintained
It is spaced duration.Specifically, kTi+1=kTi+ a (hT-ht), a are constant, the constant be positive number and with refrigerator volume, environment temperature
Etc. correlations.
Meanwhile refrigerator enters next defrost gap periods, repeats step S1.
Wherein, in step S3, to prevent the frequent defrost of refrigerator, jt and minimum defrost interval time T can also be comparedmin.Such as
Fruit kt >=kTi and jt > Tmin, 4 are entered step, otherwise, return step S1.
It is understood that in the default accumulative opening time kT of a defrost gap periodsiIn, i represents the period.In ice
Case is powered before operation, kT1It is embedded in control program.First defrost period is with fixed value kT1When to preset accumulative open the door
Between, and determine that the default of next period adds up opening time kT according to the method for the present invention after defrost2, so recycle.
With reference to Fig. 2, in the another example of the present invention, the defrosting control of refrigerator includes:
The accumulative opening time kt of reality of S1 ', the current defrost gap periods of monitoring；
S2 ', the accumulative opening time kt of reality of more current defrost gap periods and presetting for current defrost gap periods
Accumulative opening time kTiIf practical accumulative opening time is greater than or equal to the default accumulative opening time kTi, enter step
S3 ', otherwise, return step S1 '；
S3 ', starting defrost, and monitor the time ht of defrost start and ending；
After S4 ', defrost, compare ht and defrost time preset value hT, to obtain the default of next defrost gap periods
Accumulative opening time kTi+1。
kTi+1The same previous embodiment of calculation method.
Further, the interval time jt of defrost is also monitored, and between step S1 ' and S2 ', when comparing the interval of defrost
Between jt and maximum defrost interval time preset value Tmax, minimum defrost interval time preset value Tmin.If Tmin<jt<Tmax, execute
The step S2 ' otherwise compares whether jt is greater than or equal to Tmax.If it is, being directly entered step S3 ', otherwise, it is meant that
jt<Tmin, then return step S1 '.
The difference of the embodiment and embodiment illustrated in fig. 1 is the sequence of judgment step.
In this way, the duration of next defrost gap periods can be adjusted, more specifically according to the defrost duration in each defrost period
Ground, adjusts the accumulative enabling duration in next defrost period, to adapt the defrost frequency of refrigerator to the practical operation feelings of user
Condition, defrosting control is more accurate and intelligent, achievees the effect that energy saving, fresh-keeping.
It should be appreciated that although this specification is described in terms of embodiments, but not each embodiment only includes one
A independent technical solution, this description of the specification is merely for the sake of clarity, and those skilled in the art should will say
As a whole, the technical solution in each embodiment may also be suitably combined to form those skilled in the art can for bright book
With the other embodiments of understanding.
The series of detailed descriptions listed above only for feasible embodiment of the invention specifically
