Description
Technical field
The present invention relates to the control fields of air-conditioning, specifically, being related to a kind of air-conditioning automatically cleaning control method, realizing this side
The air-conditioning and computer readable storage medium of method.
Background technique
Air-conditioning is common household electrical appliance, when people use air-conditioning, is usually closed door and window, indoor air matter
Amount cannot ensure.Also, when operation of air conditioner for a period of time after, air-conditioning internal components will gather dust, these dusts with
The wind of air-conditioning blowout is blown to room air, influences human health.
As people's health requirement is higher and higher, people more focus on the cleaning of living electric apparatus class, and air-conditioning, which is used as, to be blown
The automatically cleaning technology of the device of wind cooling and warming, air-conditioning has been widely used in a plurality of types of air-conditionings.Therefore, when air-conditioning is transported
After row a period of time, an automatically cleaning operation will be needed to be implemented, to remove the dust in air-conditioning.
But certain time is needed since air-conditioning executes automatically cleaning operation, if frequently executing automatically cleaning operation, it is possible to
Lead to the waste of electric energy, and influence the use of user, but if not executing automatically cleaning operation for a long time, will lead to a large amount of ash
Dirt is blown in room air from inside air-conditioning.Therefore, judge to execute the time of automatically cleaning operation and execute automatically cleaning operation
Duration is primary study object of the air-conditioning from peace and quiet control.
Judgement at present enters self-cleaning method mainly by environment temperature, the inner tube temperature during operation of air conditioner
And the judgement of the Multiple factors such as current value of multiple blowers of air conditioner indoor unit, judgment mode is single, and there are the feelings such as erroneous judgement
Condition.
Such as a kind of present air conditioner automatically cleaning control method is by obtaining air-conditioning in air conditioner refrigerating operational process
The electronic expansion valve opening of device compares electronic expansion valve opening and standard expansion valve opening, and is judged whether according to comparison result
Control air conditioner enters automatically cleaning mode, manually controls air conditioner without user and enters automatically cleaning mode.But due to every
There is also increase device abrasion, environmental working condition etc. with service life in addition to ontology difference for the electronic expansion valve opening of platform air-conditioning
Influence, a possibility that this method has judging a poor reliability, erroneous judgement, is high, so also need to each influence factor into
Row weight analysis, to avoid erroneous judgement.
Another self-cleaning control method of air-conditioning is the accumulative operation in automatically cleaning mode by judging compressor
Whether duration is in defined threshold range, thus judge whether to continue cleaning treatment, but this method can not be according to sky
The clean level of itself is adjusted to provide reasonable cleaning time.
A kind of automatically cleaning control method there are also air conditioner is that the coil pipe temperature of indoor unit is obtained in air conditioner refrigerating operaton
The dew-point temperature of degree and air, and multiple blower current values of indoor unit in preset time are obtained, calculate multiple wind of indoor unit
The average value of electromechanical flow valuve judges whether according to the coil temperature of indoor unit, the dew-point temperature of air and average value to indoor unit
Execute automatically cleaning operation.But since the current value of motor can be by grid fluctuations affect, and can not accurately judge to need automatically cleaning
Time.
In addition, existing self-cleaning control method is to normally enter self-cleaning operation, but it can not be according to work around
The time required to the clean level of condition environment and air-conditioning rationally enters automatically cleaning and provides automatically cleaning, so that user be allowed voluntarily to close
The selection cleaning time of reason avoids cleaning erroneous judgement from influencing user's normal use air-conditioning.
Summary of the invention
The first object of the present invention, which is to provide one kind, can fully consider that the actual use operating condition of air-conditioning and environment influence
Air-conditioning automatically cleaning control method.
The second object of the present invention is to provide a kind of air-conditioning for realizing above-mentioned air-conditioning automatically cleaning control method.
The third object of the present invention is to provide a kind of computer-readable storage for realizing above-mentioned air-conditioning automatically cleaning control method
Medium.
The first purpose to realize the present invention, air-conditioning automatically cleaning control method provided by the invention include calculating and generating mesh
The actual temperature change curve for marking object, the actual temperature change curve for calculating target object are corresponding with the target object default
The related coefficient of temperature variation curve then issues automatically cleaning prompt information if related coefficient is less than the first preset threshold.
By above scheme as it can be seen that the present invention use air-conditioning actual motion when target object actual temperature change curve and
The foundation that the related coefficient of preset temperature change curve judges as automatically cleaning, in this way, being not the environment simply with air-conditioning
Temperature, inner tube temperature as single judgement object, and be according to the case where air-conditioning actual motion as judgment basis so that
The judgement for carrying out automatically cleaning operation to air-conditioning is more accurate, avoids only being used only fixed parameter as judgment basis, raising is sentenced
Disconnected accuracy.
One Preferable scheme is that, issue automatically cleaning prompt information include: that self-cleaning duration is determined according to related coefficient,
And issue the advisory information of automatically cleaning duration.
It can be seen that the present invention not only determines the time for executing automatically cleaning operation according to related coefficient, also according to phase relation
Number determines the duration for executing automatically cleaning operation, to preferably user be prompted to carry out automatically cleaning operation according to the actual situation.
Further embodiment is that automatically cleaning duration and related coefficient are negatively correlated, specifically, being determined according to related coefficient from clear
Clean duration, and whether the advisory information for issuing automatically cleaning duration includes: to judge related coefficient less than the first preset threshold and big
In the second preset threshold, in this way, it is proposed that a length of first duration when automatically cleaning；If related coefficient is less than the second preset threshold, then build
Discuss a length of second duration when automatically cleaning；First duration is less than the second duration.
As it can be seen that indicating that the clean-up performance inside air-conditioning is higher, needing to be implemented the automatically cleaning time gets over when related coefficient is bigger
It is short, if related coefficient is smaller, indicates that the clean-up performance inside air-conditioning is lower, it is longer to need to be implemented the automatically cleaning time.Therefore, originally
The scheme of invention can reasonably determine the automatically cleaning time, avoid waste of energy caused by automatically cleaning overlong time, or keep away
It is too short and cause to clean sordid situation to exempt from the automatically cleaning time.
Optional scheme is that the actual temperature change curve of target object is variation of ambient temperature curve or inner tube temperature
At least one of change curve.
It can be seen that actual variation of ambient temperature trend, inner tube temperature all variation tendencies may when due to operation of air conditioner
Because changing inside air-conditioning there are reasons such as dusts, actual environment temperature, the variation feelings of inner tube temperature are used
Condition can accurately react air-conditioning cleaning inside situation and suggest adaptable automatically cleaning operation as automatically cleaning judgment basis.
Further scheme is, the actual temperature change curve of target object includes variation of ambient temperature curve and interior
Pipe temperature variation curve；The actual temperature change curve preset temperature variation corresponding with the target object for calculating target object is bent
The related coefficient of line, if related coefficient is less than the first preset threshold, issuing automatically cleaning prompt information includes: to calculate environment temperature to become
Change the related coefficient of curve and default variation of ambient temperature curve, and calculates inner tube temperature change curve and the change of default inner tube temperature
Change the related coefficient of curve, it is corresponding with higher one of priority level in inner tube temperature change curve in variation of ambient temperature curve
Related coefficient less than the first preset threshold when, issue automatically cleaning prompt information.
It, can be with as it can be seen that by the temperature variation curve that sets multiple and different target object as automatically cleaning judgment basis
The priority level of the temperature variation curve of different target object is adjusted according to the actual situation, so that the judgement of automatically cleaning operation
It is more accurate.
Further scheme is that preset temperature change curve is the temperature change song for running record after air-conditioning is installed for the first time
Line.
When due to being run for the first time after air-conditioning installation, cleannes highest in air-conditioning, the temperature run for the first time after being installed with air-conditioning
Comparison benchmark of the change curve as subsequent actual temperature change curve is spent, can accurately judge the clean-up performance of air-conditioning,
Automatically cleaning prompt is more accurate.
Further scheme is that preset temperature change curve includes refrigeration mode preset temperature change curve and heating
Mode preset temperature change curve；Calculate the actual temperature change curve preset temperature corresponding with the target object of target object
Before the related coefficient of change curve, current operational mode is determined, and present mode of operation is obtained according to current operational mode
Corresponding preset temperature change curve.
It can be seen that distinguishing the different operational modes of air-conditioning, and different temperature is determined according to actual operational mode
Change curve is capable of the variation tendency situation of accurate reaction temperature, more accurate to self-cleaning judgement.
Further scheme is that the actual temperature change curve that calculating generates target object includes: to set using temperature
Coefficient, operation of air conditioner duration calculate target object temperature variation curve as parameter.
Since the target object temperature variation curve of air-conditioning is calculated using specific parameter, so that temperature variation curve
The cleaning situation inside reaction air-conditioning being accurately calculated, can be improved the accuracy of automatically cleaning suggestion, so that automatically cleaning is held
Row time and duration are more accurate, it is ensured that the clean-up performance after automatically cleaning inside air-conditioning.
To realize the second purpose for being, air-conditioning provided by the invention has shell, is provided with circuit board, circuit in shell

The invention will be further described with reference to the accompanying drawings and embodiments.
Specific embodiment
Air-conditioning automatically cleaning control method of the invention is applied on air-conditioning, which can be hanging air conditioner or cabinet type sky
It adjusts, air-conditioning has shell, and one piece of circuit board is provided in shell, and circuit board is equipped with processor and memory, and memory is deposited
Computer program is contained, processor, which executes the computer program, can be achieved on the air-conditioning automatically cleaning control method.
Air-conditioning automatically cleaning control method embodiment:
The present embodiment is applied on air-conditioning, and referring to Fig. 1, step S1 is first carried out, and obtains the current operational mode of air-conditioning, example
Such as determine current operation of air conditioner in refrigeration mode or heating mode.By in this present embodiment, operation of air conditioner refrigeration mode with
Under heating mode, temperature variation curve is not identical, and the parameter for calculating temperature variation curve is not also identical, therefore, it is necessary to
The current operational mode of air-conditioning is obtained first.
Then, step S2 is executed, acquires the environment temperature and inner tube temperature of air-conditioning, in the present embodiment, the environment of air-conditioning
Temperature is the environment temperature in the region that air-conditioning is installed, such as return air temperature sensor is arranged at air-conditioner air outlet, by this
Return air temperature sensor obtains the environment temperature of air-conditioning.In addition, temperature sensor is arranged on the inner tube periphery of air conditioning chamber and examines
Survey the temperature of air-conditioning inner tube.
Then, step S3 is executed, calculates and generates the actual temperature change curve under corresponding operational mode.For example, current
Operational mode is refrigeration mode, then calculates actual variation of ambient temperature curve according to the environment temperature of acquisition.Specifically, practical
Variation of ambient temperature curve following formula can be used calculated:
TRing+1=K1×t1+K2×TIf×t1+TRing(formula 1)
The present embodiment, the detection and calculating of environment temperature are to be carried out with certain detection cycle, such as each is detected
Period is 1 second, in formula 1, TRingIt is the environment temperature that current period detects, and TRing+1It is the ring of the next cycle calculated
Border temperature, K1It is the proportionality coefficient that indoor environment temperature changes over time after air-conditioning is switched on, t1It is that air-conditioning is switched on and enters current
To the runing time length at current time, T after operational modeIfIt is the temperature currently set, K2It is set temperature TIfRatio system
Number, i.e. coefficient of the set temperature value to the influence degree of subsequent time environment temperature.Preferably, K1And K2It is all preset
Coefficient.
When calculating multiple and different after the environment temperature inscribed, the environment temperature production that can be inscribed when will be multiple is corresponding
Curve forms a variation of ambient temperature curve.
It is calculated correspondingly, following formula can be used in inner tube temperature:
TPipe+1=K3×t2+K4×TIf×t2+TPipe(formula 2)
Wherein, the detection and calculating of inner tube temperature are also to be carried out with certain detection cycle, such as each detection is all
Phase is 1 second, in formula 2, TPipeIt is the inner tube temperature that current period detects, and TPipe+1It is the inner tube of the next cycle calculated
Temperature, K3It is the air-conditioning booting proportionality coefficient that indoor inner tube temperature changes over time later, t2It is that air-conditioning is switched on and enters current fortune
To the runing time length at current time, under normal circumstances, t after row mode1With t2It is equal, TIfIt is the temperature currently set,
K4It is set temperature TIfProportionality coefficient, i.e. coefficient of the set temperature value to the influence degree of subsequent time inner tube temperature.It is preferred that
, K3And K4It is all preset coefficient.
When calculating multiple and different after the inner tube temperature inscribed, the inner tube temperature production that can be inscribed when will be multiple is corresponding
Curve forms an inner tube temperature change curve.
Then, step S4 is executed, the corresponding preset temperature change curve of target object under corresponding operational mode is obtained.Example
Such as, if air-conditioning currently in cooling mode, obtains preset variation of ambient temperature curve and internal pipe temperature under refrigeration mode
Spend change curve.Preferably, preset variation of ambient temperature curve is the environment temperature recorded air-conditioning installation is run for the first time later when
Change curve is spent, when due to running for the first time after air-conditioning installation, air-conditioning cleaning inside degree is higher, runs for the first time after installing with air-conditioning
Benchmark of the variation of ambient temperature curve as subsequent judgement can be accurately judged to the actual clean condition of air-conditioning.Further, since
Preset variation of ambient temperature curve is to run recorded curve for the first time after air-conditioning installation, rather than use unified, solid
Fixed temperature variation curve, the temperature variation curve that is preset, unified, fixing compared to when rising using air-conditioning factory, this
Embodiment can be avoided the feelings for leading to that air-conditioning cleannes are judged with inaccuracy because of air-conditioning individual difference and running environment difference
Condition.
Correspondingly, preset inner tube temperature change curve is also the inner tube temperature recorded when running for the first time after air-conditioning is installed
Change curve.
Then, step S5 is executed, the related coefficient of actual temperature change curve and target temperature change curve is calculated.Example
Such as, it is carried out pair using the preset variation of ambient temperature curve that currently practical variation of ambient temperature curve and step S4 are obtained
Than, and calculate the related coefficient of two temperature variation curves.It is assumed that in cooling mode, the change of environment temperature
Changing curve is the curve gradually declined, set temperature is dropped to from currently practical environment temperature, if the ring of currently practical calculating
Border temperature variation curve and preset variation of ambient temperature curve identical, then related coefficient α is 1, if currently practical calculating
Variation of ambient temperature curve and preset variation of ambient temperature curve be not identical, then related coefficient α is the numerical value less than 1, may
For 0.9 or 0.8 equal numerical value.The related coefficient of two curves is higher, indicates that the similarity of two curves is higher, inside air-conditioning
Clean-up performance is also higher.
In the present embodiment, it can be calculated using the calculation method of the related coefficient of two mathematically usually used curves real
The related coefficient of border variation of ambient temperature curve and default variation of ambient temperature curve, such as can be calculated using the following equation:
Wherein, r (x, y) is the related coefficient of actual ambient temperature change curve Yu default variation of ambient temperature curve, Cov
(x, y) is the covariance of x and y, and Var [x] is the variance of x, and Var [y] is the variance of y, and x is actual ambient temperature change curve
Function, y are the functions of default variation of ambient temperature curve.It is of course also possible to use formula 3 calculates actual inner tube temperature variation
Related coefficient between curve and preset inner tube temperature change curve, at this point, x is actual inner tube temperature change curve, y is
Default inner tube temperature change curve.
Then, step S6 is executed, judges whether the related coefficient calculated is greater than the first preset threshold.The present embodiment
In, the first preset threshold is 0.9, and certainly, in actual use, the first preset threshold is adjustable, such as is set as
0.95 or 0.8.If the actual temperature change curve of target object only one, i.e., only calculate build environment temperature change
Curve, then step S6 only compares the phase relation between actual ambient temperature change curve and preset variation of ambient temperature curve
Whether number is greater than the first preset threshold, generates inner tube temperature change curve if only calculating, then step S6 is only relatively practical
Whether the related coefficient between inner tube temperature change curve and preset inner tube temperature change curve is greater than the first preset threshold.Such as
Fruit calculates variation of ambient temperature curve and inner tube temperature change curve simultaneously, then needs to consider priority level between the two.
In the present embodiment, step S2 acquires environment temperature and inner tube temperature, and step S3 calculating generates reality
Therefore variation of ambient temperature curve and practical inner tube temperature change curve when executing step S6, need to set a priority scheduling
Grade.Referring to fig. 2, step S11 is first carried out, calculates actual variation of ambient temperature curve and preset variation of ambient temperature curve
Between the first related coefficient, then execute step S12, calculate actual inner tube temperature change curve and preset inner tube temperature
The second related coefficient between change curve, then execute step S13, judge variation of ambient temperature curve priority level whether compared with
Height judges actual ambient temperature change curve relative to preset variation of ambient temperature curve if so, thening follow the steps S14
Whether the first related coefficient is greater than the first preset threshold, if so, thening follow the steps S16, it is default that confirmation related coefficient is greater than first
Threshold value, the i.e. judging result of step S6 are yes.If the judging result of step S14 be it is no, then follow the steps S17, confirmation is related
Coefficient is not more than the first preset threshold, i.e. the judging result of step S6 is no.
If the judging result of step S13 is no, then it represents that the priority level of inner tube temperature change curve is higher, then executes
Step S15 judges that practical inner tube temperature change curve is relative to the second related coefficient of preset inner tube temperature change curve
No to be greater than the first preset threshold, if so, thening follow the steps S18, confirmation related coefficient is greater than the first preset threshold, i.e. step S6's
Judging result is yes.If the judging result of step S15 be it is no, then follow the steps S17, confirmation related coefficient is pre- no more than first
If threshold value, i.e. the judging result of step S6 is no.
When the judging result of step S6 be it is yes, indicate that the clean-up performance of air-conditioning is higher, do not need execute automatically cleaning operation, this
When, step S10 is executed, into preset operational mode, such as into refrigeration mode and is maintained at refrigeration mode work.If step
Suddenly the judging result of S6 is no, indicates that the current clean-up performance of air-conditioning is lower, needs to carry out self-cleaning operation, execute step at this time
Rapid S7 issues automatically cleaning prompt information.It is not direct when related coefficient is not more than the first preset threshold in the present embodiment
Automatically cleaning operation is executed, but can just be held only after receiving the instruction into automatically cleaning operation to sending prompt information
The operation of row automatically cleaning.
Preferably, variation of ambient temperature curve and the priority level of inner tube temperature change curve can be preset, can also
To be set or modified their own by user, such as corresponding key is set on a remote control, voluntarily environment temperature is become by user
The priority level for changing curve and inner tube temperature change curve is modified.
Since the related coefficient of calculating is different, indicate that the clean-up performance of air-conditioning is not identical, therefore, it is necessary to bases to calculate
Related coefficient specific value determine suggest automatically cleaning duration.A kind of scheme is that automatically cleaning duration and related coefficient are at anti-
Than that is, related coefficient is bigger, and automatically cleaning duration is shorter, and related coefficient is smaller, and automatically cleaning duration is longer, and such case can be used
Preset formula calculates automatically cleaning duration.
Another scheme is can be confirmed according to the fixed automatically cleaning duration of related coefficient size suggestion referring to Fig. 3
After related coefficient is less than the first preset threshold, step S21 is executed, judges whether related coefficient is greater than second threshold, that is, judges phase
Whether relationship number is greater than second threshold and less than the first preset threshold, wherein the second preset threshold less than the first preset threshold,
Such as second preset threshold be 0.7 or 0.6.If related coefficient is greater than the second preset threshold, then it represents that related coefficient is opposite
It is higher, have certain dust in air-conditioning, but very not dirty, at this point, execute step S22, it is proposed that a length of first when automatically cleaning
Duration, such as show on the control panel of air-conditioning the automatically cleaning duration of suggestion, or is broadcasted by way of voice broadcast
One self-cleaning duration.If step S21 judges that related coefficient is less than second threshold, indicate that related coefficient is smaller, inside air-conditioning
It is dirtier, then follow the steps S23, it is proposed that a length of second duration when automatically cleaning, and the second duration is greater than the first duration, with sufficiently right
It is cleaned inside air-conditioning.
After issuing automatically cleaning prompt information, step S8 is executed, judges whether to receive automatically cleaning instruction, such as judge whether
The self-cleaning phonetic order that user presses the self-cleaning key of remote controler or user issues is received, if received certainly
Cleaning instruction, thens follow the steps S9, executes automatically cleaning operation, otherwise, step S10 is executed, according to the operational mode currently set
Corresponding operation is executed, such as continues to execute refrigerating operation.In this way, in the case where issuing automatically cleaning prompt, if user needs
It to be not intended to carry out automatically cleaning at once using air-conditioning at once, can satisfy the use demand of user, exit current fortune in user
After row mode, reresent and carry out self-cleaning suggestion, or issue automatically cleaning suggestion again in booting next time, to reduce to user
Use the influence of air-conditioning.
In above-described embodiment, the current operational mode of air-conditioning is refrigeration mode, and when practical application, the operational mode of air-conditioning is also
It can be heating mode, at this point, when step S3 calculates the change curve of actual ambient temperature, parameter K that formula 1 uses1And K2It will replace
It is changed to preset coefficient under heating mode, it is identical, when calculating the change curve of practical inner tube temperature, ginseng that formula 2 uses
Number K3And K4Preset coefficient under heating mode will be replaced with.In addition, step S4 acquisition will be air-conditioning under heating mode
When starting for the first time after installation, the variation of ambient temperature curve and inner tube temperature change curve that are recorded under heating mode.
In addition, related coefficient is only divided into three grades by the flow chart of Fig. 3, that is, it is greater than the first preset threshold, is less than
First preset threshold and it is greater than the second preset threshold, less than the second preset threshold, when practical application, one can be increased less than the
The third predetermined threshold value of two preset thresholds, i.e., if when related coefficient is less than third predetermined threshold value, it is proposed that a length of the when automatically cleaning
Three durations, and the second duration of third time length ratio is longer.
Another optional scheme is after starting of air conditioner, to be introduced into refrigeration mode, after running a period of time, enter back into system
Heat pattern during operating in refrigeration mode and heating mode, calculates variation of ambient temperature curve.Then, air-conditioning is obtained
Enter the preset variation of ambient temperature curve under heating mode after first running refrigeration mode, calculates the phase relation of this two curves
Number is determined the need for executing automatically cleaning operation according to the numerical value of related coefficient, if necessary to execute automatically cleaning operation, be given
It is recommended that automatically cleaning duration.
Alternatively, being introduced into heating mode after starting of air conditioner, after running a period of time, refrigeration mode is entered back into, system is operated in
During heat pattern and refrigeration mode, variation of ambient temperature curve is calculated.Then, after acquisition air-conditioning first runs heating mode
Preset variation of ambient temperature curve under into refrigeration mode, calculates the related coefficient of this two curves, according to related coefficient
Numerical value determine the need for execute automatically cleaning operation, if necessary to execute automatically cleaning operation, when giving the automatically cleaning of suggestion
It is long.
Certainly, in above-mentioned scheme, actual variation of ambient temperature curve can be replaced by actual inner tube temperature and become
Change curve, correspondingly, preset variation of ambient temperature curve is replaced by preset inner tube temperature change curve.In addition, this hair
Bright operational mode is not restricted to refrigeration mode or heating mode, can also be air supply pattern, dehumidification mode etc..
In addition, it is one optional public that step S3, which calculates formula used in the actual variation of ambient temperature curve of generation,
Formula, practical application are can be substituted for other formula, or the environment temperature that while calculating each without using formula inscribes, but straight
The environment temperature inscribed when acquiring multiple in a period of time using temperature sensor is connect, and the variation for forming actual ambient temperature is bent
Line also can be realized the purpose of the present invention.
Variation of ambient temperature curve or internal pipe temperature after being installed due to the present invention according to each air-conditioning when actual motion
Therefore degree change curve can be eliminated because of the individual between different air-conditionings as the foundation of subsequent judgement air-conditioning clean-up performance
The situation that inaccuracy is calculated air-conditioning clean-up performance caused by difference, actual installation environmental difference, executes air-conditioning automatically cleaning
The calculating of time and duration is more accurate, on the one hand avoid because automatically cleaning duration it is too long caused by waste of energy, another party
Face avoids cleaning sordid situation caused by automatically cleaning duration is too short.
