Completed by the way of external heat source more than defrost in art, so as to adds additional thermic load.
At present, the defrost of refrigerator is mainly based upon the length of each defrost run time and per defrost twice between operation
Interval time carries out the conceptual design of defrost.The time length that the length of defrost run time is heated when referring to each defrost.Change
It is directly to pass through electricity on evaporator of refrigerator heating tube is heated to eliminate frost on an evaporator during frost operation, thus is straight
It is connected on and heat is produced in refrigerator.This process increased the thermic load of refrigerator, afterwards again by the refrigeration of compressor come these
Thermic load is removed, so as to produce extra energy loss.Therefore the heat time is shorter, then the heat for producing is also smaller, to energy consumption
Influence it is also fewer.The comparing of this time length, is based in identical heating power.For same refrigerator, in heating
In the case of power increase, total heat time can also shorten, but the heat of heating does not have big change.This point it may be said that
Bright, the energy that each defrost of refrigerator needs is similar, so to change defrost run time when heating power is specified
Length, it is general unlikely.Another is the time of defrost interval, interval time is more long, then defrost operation energy consumption
Average value is smaller.But the length of this interval time, also there is various requirement in a standard.And the time of defrost interval
More long, evaporimeter frosting is more serious, when the ventilation of evaporator is had influence on, can also influence refrigerating efficiency to increase energy consumption.Defrost is transported
Capable exiting mainly is controlled by setting the temperature controller of ad-hoc location (such as evaporator top) on an evaporator, works as temperature
When the temperature that controller detects evaporator top reaches setting (being typically set at 5 °), defrost operation is exited.
And in the prior art, being mainly based upon above-mentioned principle carries out the design of defrost scheme.Prior art is carried below
The technical scheme of confession is illustrated, scheme one：Obtain the number of times of refrigerator open, when the number of times of refrigerator open is more, increaseization
Frost operation number of times, but defrost operation exit by temperature controller control, therefore shorten defrost operation time, only
It is the interval time for changing defrost operation.Scheme two：The cumulative time of refrigerator open is obtained, according to the refrigerator open cumulative time
Change come change defrost run when interval time, if opening time exceed setting time, it is thus regarded that refrigerator need plus
The time interval of fast defrost operation, and defrost operation is exited by temperature controller control, therefore opening time in this kind of mode
The cumulative time of refrigerator defrost operation more long is also more long, and the interval time of defrost operation is shorter.Scheme three：By accumulative enabling
Time calculates the temperature that control defrost operation is exited with number of times, by obtaining the parameter of environment temperature and ambient humidity, calculates
Into the water of refrigerator, the temperature that defrost operation is exited then is calculated, meet what is exited when defrost is run to evaporator temperature
During temperature, defrost operation is exited, the time of defrost operation is reduced with this.
It is the pattern exited using the temperature control defrost operation of detection evaporator, wherein just in above-mentioned three kinds of schemes
In case one and two, run due to needing temperature control to exit defrost, and defrost operation can defrost completely, but frosting degree every time
When less, the normal operation of refrigerator is had no effect on, therefore energy consumption is larger；Although in scheme three defrost can be exited by control
The temperature of operation incomplete defrost subzero with saving energy consumption, but this controlling mechanism needs being transported to defrost repeatedly
The capable temperature that exits carries out calculating complex.

Additionally, being calculated without the temperature that exits to defrost operation repeatedly in the program, it is only necessary to coordinate two kinds of defrost operation moulds
The conversion of formula, project plan comparison is simple.
Shown in reference picture 2, another embodiment of the present invention provides a kind of refrigerator defrosting control method, comprises the following steps：
201st, refrigerator starts refrigeration.
202nd, timing is started by timer after refrigerator starts refrigeration, judges whether timing reaches scheduled duration.
The scheduled duration is defined as the defrost cumulative time, and scheduled duration is more than or equal to adjacent second mode defrost twice
Time interval between operation.If otherwise continuing to run with refrigeration；If then performing step 203.
203rd, add up to start second mode defrost operation after judging refrigerator self-starting refrigeration after timing to scheduled duration
Number of times.
Wherein, second mode defrost is operated in predetermined defrost operation duration with constant power defrost.
204th, when the accumulative number of times for starting second mode defrost operation is more than or equal to M times, then first mode is started
Frost operation, and when the temperature of the evaporator of refrigerator reaches predetermined temperature backed off after random first mode defrost operation.
If the number of times for the 205, adding up to start second mode defrost operation is less than M times, the refrigerator doors in preset duration are judged
Opening.
If the 206, the number of times that refrigerator doors are opened is more than or waits more than or equal to the duration that n times and/or refrigerator doors add up unlatching
In the first duration, then start first mode defrost operation, and when the temperature of the evaporator of refrigerator reaches predetermined temperature backed off after random
The first mode defrost operation.
If the 207, the number of times that refrigerator doors are opened is less than n times and refrigerator doors add up the duration opened less than the first duration, root
According to the opening of refrigerator doors, the predetermined defrost operation duration of second mode defrost operation is calculated.
According to the opening of refrigerator doors in specific step 207, the predetermined defrost fortune of second mode defrost operation is calculated
Include during row：The duration calculation refrigerator that the number of times and refrigerator doors opened according to refrigerator doors are opened every time enters in scheduled duration
Amount of moisture；The predetermined defrost operation duration that second mode defrost runs is calculated according to the amount of moisture entered in scheduled duration.
The amount of moisture for wherein being received in refrigerator is mainly relevant with several reasons once：
First：The compartment volume of refrigerator is bigger, and the moisture for receiving is more, and during refrigerating operaton, it is big that refrigerator receives
The moisture permanent set of amount is on an evaporator.Second：Extraneous moisture is entered into when in refrigerator, and the refrigerator doors opening time is more long,
The moisture for then entering is also more, can bring more hydrogenesis on an evaporator.3rd：In fixed duration, door opening times
More (certainly it is assumed here that the time span opened the door every time is the same), then the moisture for entering is also more.4th：It is relative in air
Humidity is higher, illustrates that the amount of moisture contained in air is also higher, so also easily produces more hydrogenesis in evaporator.
So, entering into the amount of moisture entered in refrigerator can be calculated with following formula.
Ni:The door opening times of refrigerator difference compartment；
li:The volume of different compartments；
Hh:Refrigerator local environment temperature moisture ratio corresponding with relative humidity, g/kg；
Hli:In refrigerator under different compartment corresponding temperatures with humidity under water content, g/k；
γ：Air specific volume under different compartment temperatures, m3/kg；
n：The compartment quantity of refrigerator.
Above-mentioned formula one is mainly used for studying refrigerator and opening the door every time (ignoring refrigerator doors each opening time in the formula one
Influence) after can bring how many moisture into and enter, and last all condense on an evaporator.Exemplary：For frost-free refrigerator, ice
Relative humidity inside case is 30%, if exterior relative humidity is 85%, it is possible to calculated after opening the door every time by changing
Air and the moisture that produces, it is assumed that the ratio more ventilated is 100% (assuming that refrigerator doors each opening time is all changed enough
Air in refrigerator compartment), can calculate different refrigerators can bring that how much moisture enters into evaporation under different door opening times
On device, need to produce how many heats that these moisture are melted into water needs because of congealing into ice in each defrost interval
Heat.
For ease of illustration the calculating of above-mentioned formula, listing one group of data carries out example.
If：
Volume of refrigerating chamber 250L, temperature is 5 DEG C, and relative humidity is 40%, and air specific volume is 0.788m3/kg, and water capacity is
2.17g/kg.Refrigerating chamber volume is 150L, and temperature is -18 DEG C, and relative humidity is 30%, and air specific volume is 0.723m3/kg, is contained
Moisture is 0.23g/kg.
When environment temperature is 32 DEG C, and relative humidity is 85%, corresponding air specific volume is 0.864m3/kg, and water capacity is
26.17g/kg
The amount of moisture entered when then each compartment (refrigerating chamber and refrigerating chamber) is opened the door one time：
G=0.15* (26.17-0.23)/0.723+0.25* (26.17-2.17)/0.788
=12.8 (g)
If respectively opened the door 3 times, the amount of moisture for entering is 38.4g.
And second mode defrost operation predetermined defrost operation duration it is general determined according to frosting degree, frosting degree with open the door
The amount of moisture for causing entry into is relevant, and convolution one calculates predetermined defrost operation duration.
T=G × (λ+K × △ T)/W (formula two)
G：The amount of moisture of entrance,
λ：The heat of solution of ice,
K：The thermal conductivity factor of ice,
ΔT：Ice rises to the temperature difference of zero degree before dissolving,
W：The heating power of refrigerator defrost.
208th, second mode defrost operation is started according to predetermined defrost operation duration.
Wherein, in step 201 to start refrigerating operaton first, therefore timer is directly initiated in step 202. start
Timing, and after a second mode defrost operation or first mode defrost operation is started, timer is reset again to pre- timing
Length carries out timing, and performs step 202~208 in the full scheduled duration Posterior circle of meter；Wherein starting a second mode defrost
After operation or first mode defrost operation, reset timer carries out timing to scheduled duration again, and timer can be referred in defrost
Operation carries out timing when starting, it is also possible to refer to that timer starts timing in defrost end of run, if timer runs in defrost
At the end of start timing, then need to count the time interval between the adjacent defrost of the second mode twice operation of full phase；If timer is being changed
Frost operation carries out timing when starting, then timer needs the time length of the defrost operation that accumulative meter will completely start and adjacent
The defrost of second mode twice operation between time interval.In addition after first mode defrost operation is started, step 203
Middle control process amendment judges that refrigerator adds up to start the number of times of second mode defrost operation from after this first mode defrost operation,
Number of times to starting second mode defrost operation adds one.
In theory, defrost can just be reached to the cold that the heat that evaporator is provided is equal to the moisture that neutralizing freezes
Purpose, but following several special circumstances are still present：
Environment residing for evaporator is more special, and the heat-insulating property on evaporator periphery is poor, might have a part of heat
Amount will lose.Additionally, frosting also has one it is a key issue that frost can mainly condense in the bottom of evaporator on an evaporator,
It is to place vertically for refrigerator due to evaporator, this is conducive to water to fall naturally, air circulation is from lower to upper part fortune
OK, such water content air higher first can enter from the bottom of evaporator, then be run up by evaporator, in this fortune
In capable process, because the temperature of evaporator is low, substantial amounts of moisture can first build-up ice in the inlet port of evaporator (i.e. evaporator
Bottom), more tiny hydrone is then entered on evaporator position higher and condensed, and this also complies with evaporation of the evaporator in bottom
Temperature is high, and more big hydrone first condenses, and thinner hydrone then condenses in the relatively low evaporator top of evaporating temperature.
And run with the second mode defrost of the predetermined defrost operation duration of predetermined power, mainly consider frosting on evaporator
Total amount and heat relation, and evaporator bottom frosting it is how many also mainly with enter amount of moisture number it is relevant, so
Predetermined defrost operation duration under second mode defrost operation also should be relevant with this, using above-mentioned door opening times and time shadow
The formula of frosting degree is rung, the time (the predetermined defrost operation duration under second mode defrost operation) of defrost can be automatically calculated,
Just can so play a part of energy-conservation.Refrigeration can not be influenceed in view of frosting on refrigeration for refrigerator operational reliability requirement evaporator
Performance, i.e.,：First, the coefficient of heat transfer of evaporator, second are influenceed after evaporator surface frosting：Evaporator surface frosting excessively hinders
The circulating ventilation in air channel, finally also influences whether refrigeration performance.Even if several special circumstances in the presence of more than, as long as on evaporator
Frosting can not influence refrigeration performance i.e. within the acceptable range, however, it is contemplated that above-mentioned several special circumstances, only with second
Pattern defrost operation may not ensure that defrost effect, if this is because the heat that second mode defrost operation is provided can not be by
Frosting on evaporator is dissolved completely, then adding up frosting on certain hour evaporator still can influence refrigeration performance, therefore this hair
Bright embodiment further adds first mode defrost operation.The characteristics of for evaporator defrost, steamed in embodiments of the invention
Defrost on hair device is set as two kinds of control modes, and one kind (leans on temperature control escape mechanism reality for first mode defrost operation
It is existing), another second mode defrost operation (being realized by setting predetermined defrost operation duration).Second mode defrost runs, control
Local defrost on evaporator.And first mode defrost operation is then controlled by the temperature sensor for setting on an evaporator,
Control the thorough defrost of evaporator.
As above-mentioned Fig. 3 provides a kind of example of defrosting control, wherein comprising the operation of first mode defrost twice (for the first time
First mode defrost operation 20min, second first mode defrost operation 21min), and three second mode defrosts operation
(being 6min), wherein comprising three second mode defrosts operation between the operation of first mode defrost twice, data display is passed through
13.25 talentes have the defrost of first mode defrost operation, and in the prior art all according to temperature controlled defrost phase
Than due to the presence of three second mode defrosts operation, refrigerator substantially has the effect of energy-conservation.
Additionally, the defrost operation duration of the 3 second mode defrosts operation in Fig. 3 (can be illustrated in figure 3 with equal
It is 6min) or unequal (as shown in figure 4, t1, t2 and t3 duration can be with differences), the defrost of the specific operation of second mode defrost every time
Operation duration is calculated according to above-mentioned formula two.Certainly, a longer time is may be designed in when simply controlling for standard, example
As design requirement is put into first mode defrost operation more than 3 times in the door opening frequency of refrigerator, then in interval time inward swinging door
Number of times when being no more than 3 times, the defrost operation duration of each second mode defrost operation can just be unified.
Additionally, it is also contemplated that (refrigerator doors can not be gathered when the switch of some other special circumstances, such as refrigerator doors is invalid
Opening) situation, door seal is opened and closed bad situation, and other special circumstances, at these in particular cases, it is possible to determine that
There are abnormal conditions, automatically switch to first mode defrost operation, the reliability of defrost is ensured as far as possible.
