Period migration amount can be with by the counted period migration amount of frosting degree since the use habit of user will affect frosting degree
Reflect the use habit of user.By adjusting the default defrost period using period migration amount, so that the fixed defrost period be changed
To change the defrost period, also defrost variable period can be enabled according to the difference of user's use habit, so that actual use is worked as
The value in preceding defrost period is more reasonable, has not only been able to satisfy the reliability service of refrigerator system in this way, but also can lack defrost as much as possible, thus
Energy saving can preferably solve the contradictory problems between overall performance and energy consumption, help to realize overall performance and energy consumption
Balance.Specifically, the current defrost period is equal to default the sum of defrost period and period migration amount；S104 is then when accumulating work
In the case that length is more than or equal to the current defrost period, defrost pattern is run.
In one embodiment of the invention, it is preferable that period migration amount and this frosting degree are negatively correlated.
In this embodiment, the relationship of period migration amount Yu this frosting degree is specifically defined.This frosting degree is bigger, table
Bright defrost demand is also stronger, by enabling period migration amount and this frosting degree negatively correlated, can reduce period migration at this moment
Amount, to enable the defrost period used by next defrost relative to default defrost cycle time, meets defrost demand, realizes
The reliability service of refrigerator.Specifically, period migration amount can be positive value be also negative value, it is to be understood that no matter period migration
Amount is positive value or negative value, can all be reduced with the increase of this defrost duration.That is, there are a theoretic standards
Frosting degree, this is appropriate to the occasion using the default defrost period.When this frosting degree is less than standard frosting degree, period migration amount Ying Weizheng
Value realizes energy conservation to extend the defrost period, and this frosting degree is fewer, and period migration amount is bigger, can extension to some extent
The white period；Conversely, period migration amount should be negative value, to shorten the defrost period, really when this frosting degree is greater than standard frosting degree
It protects refrigerator to operate normally, and this frosting degree is more, period migration amount is more negative, i.e., value is smaller, can contract to some extent
The short defrost period.
In one embodiment of the invention, it is preferable that it is inclined that this defrost corresponding period is calculated according to this frosting degree
Shifting amount, comprising: the corresponding period migration amount of this defrost is calculated according to this defrost duration, this defrost duration be refrigerator this
Run the total duration of defrost pattern.
In this embodiment, a kind of scheme using this frosting degree calculating cycle offset is specifically described.Due to changing
White duration is related with frosting degree, and defrost duration is longer, shows that frosting degree is bigger, therefore can be since when this runs defrost pattern
Timing obtains this defrost duration to timing is stopped when exiting defrost pattern, so as to estimate the frosting of evaporator of refrigerator
Amount.In addition, directly utilizing this defrost duration calculating cycle offset, it is not necessary to first calculate frosting degree, calculating can be simplified, improve meter
Calculate efficiency.
In one embodiment of the invention, it is preferable that this defrost corresponding period is calculated according to this defrost duration
Offset, comprising: the difference of normalized frost duration and this defrost duration, as duration offset；Calculate duration offset
With the product of deviation ratio, as period migration amount, deviation ratio is greater than 0.
In this embodiment, specifically define a kind of scheme using this defrost duration calculating cycle offset, i.e., it is sharp
With deviation ratio, the duration offset of defrost is converted into period migration amount, it can be after this defrost for updating next time
The defrost period used by defrost, and calculate easy.Wherein, standard defrost duration is exactly theoretically to melt a standard frosting degree
Frost required for duration be considered as this frosting degree less than standard knots when this defrost duration is less than standard defrost duration
Frost amount, duration offset and period migration amount are positive value at this time, can extend the defrost period used by next defrost, and this is changed
White duration is shorter, this frosting degree is fewer, and duration offset and period migration amount are bigger；Conversely, working as this defrost duration
When greater than standard defrost duration, it is considered as this frosting degree and is greater than standard frosting degree, at this time duration offset and period migration amount
For negative value, the defrost period used by next defrost can be shortened, and this defrost duration is longer, this frosting degree is more, when
With regard to smaller, absolute value is bigger for long offset and period migration amount.
Fig. 2 shows the schematic flow diagrams of the defrosting control method of another embodiment of the present invention.
As shown in Fig. 2, the defrosting control method includes:
S202 calculates the current defrost period according to default defrost period and the corresponding period migration amount of last time defrost；
S204 counts the accumulation operating time and enabling total duration of refrigerator after last time defrost, and accumulation operating time is last time
The work total duration of refrigerator after defrost；
S206, according to accumulation operating time, the relationship of enabling total duration and current defrost period, it is determined whether operation defrost
Mode；
S208 calculates the corresponding period migration amount of this defrost according to this defrost duration, this defrost duration is refrigerator
The total duration of this operation defrost pattern.
In this embodiment, it has been further introduced into enabling total duration, enabling total duration is the door body of refrigerator after last time defrost
Total duration in the open state.For enabling total duration, on the one hand, to different users, different usage scenarios, such as meal
Shop and family or even different restaurants and different families, the unlatching situation of refrigerator are different, therefore as frosting degree,
Enabling total duration also can reflect the use habit of user；On the other hand, when refrigerator doors are opened, heat can enter refrigerator, make
Ice the temperature inside the box increases, and refrigeration intensity is caused to increase accordingly, and the refrigerant temperature in evaporator reduces, and further speeds up frosting, because
This enabling total duration is longer, and the demand of defrost can be stronger, more needs defrost ahead of time.By determining whether to run defrost pattern
When with reference to the enabling total duration in this period, can further promote the accuracy of judgement, help to realize overall performance and energy consumption
Balance.
In one embodiment of the invention, it is preferable that according to accumulation operating time, enabling total duration and current defrost week
The relationship of phase, it is determined whether operation defrost pattern, comprising: enabling total duration is converted into equivalent accumulation operating time；It is accumulating
In the case that the sum of operating time and equivalent accumulation operating time are more than or equal to the current defrost period, defrost pattern is run.
In this embodiment, a kind of scheme for judging whether to run defrost pattern using enabling total duration is specifically defined,
Operating time is accumulated by converting equivalent for enabling total duration, that is, thinks refrigerator open operation enabling total duration and fortune of not opening the door
It is identical that trade amount accumulates frosting increment caused by operating time, to will open the door and the operating time of refrigerator when not opening the door mutually is united
One, then compared with the current defrost period, it is high to calculate succinct and accuracy.If operating time after reunification is more than or equal to current
The defrost period, then it is assumed that frosting degree has reached defrost standard, can run defrost pattern.Specifically, enabling total duration multiplied by turn
It changes coefficient and accumulates operating time to get to equivalent, conversion coefficient can be 60 to 300.
In one embodiment of the invention, it is preferable that according to accumulation operating time, enabling total duration and current defrost week
The relationship of phase, it is determined whether operation defrost pattern, comprising: search corresponding with enabling total duration contracting when ratio, enabling total duration and
Than negative correlation when contracting；Than the product with the current defrost period when calculating contracting, to correct the current defrost period.
In this embodiment, another side for judging whether to run defrost pattern using enabling total duration is specifically defined
Case, still meets that enabling total duration is longer, more needs the principle of defrost ahead of time.By enabling total duration and a series of contractings when ratio with negative
Relevant relationship is corresponding, and enabling total duration is longer, then than smaller when contracting, the revised current defrost period is shorter, thus real
Now do sth. in advance defrost.With being contemplated that, than 0 must be greater than when contracting, but might not be less than 1, because currently the defrost period has been sharp
With the last time frosting degree adjusted defrost period, the use habit of user can be embodied to a certain extent, if current period
The enabling total duration of interior user is extremely short, then may need to extend the current defrost period instead.
In one embodiment of the invention, it is preferable that defrosting control method further include: obtain first environment temperature；It looks into
The first environment temperature corresponding defrost period is looked for, as the default defrost period.
In this embodiment, it needs to illustrate first, first environment temperature is the condensation side environment temperature of refrigerator, i.e. indoor environment
Temperature, by adjusting the default defrost period according to environment temperature, has since defrost demand is different under different environment temperatures
Help improve the judgment accuracy to defrost demand, optimize the starting opportunity of defrost pattern, both ensure that the reliability service of refrigerator,
It is reduced as far as the defrost time again, to save energy consumption.Specifically, on the one hand, air humidity tends to vary with environment temperature
The raising of degree and increase, after the high air of these humidity enters vaporization chamber, a possibility that frosting can be improved, therefore can accordingly contract
The short default defrost period；On the other hand, with the reduction of environment temperature, the compressor Homes Using TV of refrigerator can be reduced, compressor work
Make duration shortening, so that the speed of frosting slows down therewith, therefore can accordingly extend the default defrost period, conversely, with environment temperature
The raising of degree can accordingly shorten the default defrost period.By the frosting situation of statistics refrigerator at different ambient temperatures, may specify
Empirical table or empirical equation, so environment temperature is associated with the defrost period.
In one embodiment of the invention, it is preferable that defrosting control method further include: do not run the defrost in determination
In the case where mode, second environment temperature is obtained；Be greater than in the absolute value of second environment temperature and first environment temperature difference etc.
In the case where temperature difference threshold, the default defrost period is updated to the second environment temperature corresponding defrost period.
In this embodiment, it is contemplated that during constantly judging whether to run defrost pattern, environment temperature can be
Variation can further improve the accuracy to defrost demand estimation by searching the default defrost period again when changing greatly.
Conversely, influence of the environment temperature to frosting situation can be ignored when changing little, therefore the default defrost period is not modified,
It can simplified control scheme.
In one embodiment of the invention, it is preferable that defrosting control method further include: in the evaporator surface temperature of refrigerator
In the case that degree exits temperature more than or equal to defrost, defrost pattern is exited.
In this embodiment, the temperature condition for exiting defrost pattern is described.Specifically, frost, which is known from experience, to be increased when frosting
The heat exchanged thermoresistance of evaporator causes evaporator that cannot sufficiently absorb heat, and surface temperature can be far below its design value；In defrost process
In, the heat for defrost is largely absorbed by white body, and evaporator surface temperature can generate a small amount of raising；After the completion of defrost, use
It is absorbed in the heat of defrost by evaporator, so that evaporator temperature is sharply increased, therefore is by detecting evaporator surface temperature
It is no to exit temperature greater than preset defrost, aid in determining whether terminate defrost.Further, since the thermal conductivity of evaporator is good,
Even if there are evaporator everywhere frosting became uneven the case where, during defrost, the temperature of evaporator different parts is also relatively steady
It is fixed, therefore can accurately reflect frosting situation.Specifically, when running defrost pattern, using compressor shutdown, startingization
The heat of the mode defrost of white heater, i.e., aforementioned defrost is provided by defrosting heater, passes through record defrosting heater work
This defrost duration can be obtained in duration, and then estimates the frosting degree of evaporator.
In one embodiment of the invention, it is preferable that defrosting control method further include: it is corresponding to search first environment temperature
Defrost exit temperature.
In this embodiment, enabling defrost exit, temperature is related to first environment temperature, and the reasonability of its value can be improved.Tool
For body, for low-end product, since cost is relatively low, accessory is less, and it is thick to be easy to appear different parts frosting at low ambient temperatures
Thin different situation can properly increase defrost and exit temperature to guarantee abundant defrost, under high temperature environment then can appropriate reduction
Frost exits temperature to reduce energy consumption；Mid- to high-end product is tended not to occur since whole accessory is more complete and quality is more excellent
Afore-mentioned, therefore temperature is exited in the corresponding different settable identical defrost of environment temperature, such as 10 DEG C, facilitates simplified control
Strategy.Specifically, any time after obtaining first environment temperature, before operation defrost pattern can search defrost and exit temperature
Degree, such as search defrost together when searching the default defrost period and exit temperature.Further, if defrost exits temperature with environment
Temperature change then when updating the default defrost period according to second environment temperature, while updating defrost according to second environment temperature
Exit temperature.
In one embodiment of the invention, it is preferable that it is inclined that this defrost corresponding period is calculated according to this frosting degree
Shifting amount, comprising: in the case where determining operation defrost pattern, detect frosting thickness；According to this defrost pair of frosting THICKNESS CALCULATION
The period migration amount answered.
In this embodiment, another scheme for utilizing this frosting degree calculating cycle offset is specifically described.True
When running defrost pattern surely, currently detected frosting thickness can intuitively reflect this frosting degree, and frosting is thicker, then originally
Secondary frosting degree is bigger, and then can calculate period migration amount.Specifically, frosting thickness can be detected by infrared sensor,
And setting quantity and the setting position of infrared sensor are adjusted on demand.It should be noted that as previously mentioned, low-end product is in low temperature ring
It is easy to appear the different situation of different parts frosting thickness under border, therefore the setting quantity of infrared sensor need to be increased, otherwise holds
The reflection accuracy to this frosting degree is easily reduced, in this regard, the selection of cost caused by being arranged according to infrared sensor is
It is no to use this programme；Mid- to high-end product is then more uniform due to frosting thickness itself, no this puzzlement.
In one embodiment of the invention, it is preferable that defrosting control method further include: detecting that frosting thickness is less than
In the case where equal to preset thickness, defrost pattern is exited.
In this embodiment, the frosting degree condition for exiting defrost pattern is described, is detected by being kept during defrost
Frosting thickness can intuitively judge whether defrost is completed, and when frosting thickness is less than or equal to preset thickness, that is, think that defrost is complete
At, defrost pattern can be exited, convenient for operation and accuracy it is high.Specifically, to ensure that refrigerator operates normally, the target of each defrost
It is that frostization is most, therefore preset thickness can be set as to 0 or be slightly larger than 0, such as 0.2mm.
