Mode realize that specifically, Fig. 1 shows a kind of optional flow chart of this method, as shown in Figure 1, this method include it is as follows
Step S102-S108：
S102：It detects current air conditioner indoor unit and adds up operation duration；
S104：When the accumulative operation duration of the current air conditioner indoor unit of detection meets automatically cleaning detection time t, in control room
Blower is according to automatically cleaning detection wind speed air-supply；
In the present invention, automatically cleaning detection time is the interval time that air-conditioning carries out automatically cleaning detection, specifically, air-conditioning exists
After carrying out last automatically cleaning detection, it is spaced automatically cleaning detection time, automatically cleaning detection is reentered, determines whether air-conditioning needs
Want automatically cleaning.For example, initial automatically cleaning detection time built in air-conditioning system is 100 hours, current air conditioner indoor unit is being detected
After accumulative operation duration is at least up to 100 hours, self-cleaning determining process whether is needed into air-conditioning.By setting in the present invention
Automatically cleaning detection time is set, automatically cleaning whether can be needed to carry out preliminary judgement air-conditioning, judgment method is simple, realization side
Just.
When specific implementation, the present invention detects current air conditioner indoor unit first and adds up operation duration, in the current air-conditioning of detection
When indoor unit adds up operation duration arrival automatically cleaning detection time t, then detect whether air-conditioning needs automatically cleaning.Automatically cleaning detects wind
Speed is preset for detecting whether air-conditioning needs self-cleaning indoor fan wind speed, is detecting that current air conditioner indoor unit is accumulative
Operation duration reach automatically cleaning detection time t when, control indoor fan forced service automatically cleaning detect wind speed under operate, with into
Whether the subsequent air-conditioning of row needs to carry out self-cleaning judgement.
S106：Obtain input current value A1 of the indoor fan by automatically cleaning detection wind speed operating when；
S108：The corresponding standard current value A of input current value A1 and automatically cleaning detection wind speed is compared, according to comparing
As a result determine whether air-conditioning needs automatically cleaning.
When indoor fan is according to automatically cleaning detection wind speed air-supply, the input current value A1 of indoor fan, input electricity are obtained
Flow valuve A1 is related to the clean-up performance of current indoor machine filter screen or evaporator, in the case where fixed wind speed, indoor unit filtering
Net or evaporator are cleaner, and input current value A1 is smaller, opposite, indoor machine filter screen or evaporator are dirtier, input current value
A1 is bigger.The present invention has preset the corresponding standard current value of automatically cleaning detection wind speed, i.e., automatically cleaning detects wind speed when air-conditioning cleans

Flow valuve carries out secondary judgement, improves air-conditioning to the accuracy for entering the judgement of automatically cleaning mode opportunity.
During specific implementation, when input current value A1 is greater than standard current value A, illustrates that air-conditioning is messy, need certainly
Cleaning issues characterization air-conditioning and needs to carry out self-cleaning prompt information, reminds user to enter automatically cleaning mode, to remind user clear
Clean air-conditioning；When input current value A1 is less than or equal to standard current value A, illustrate that air-conditioning is cleaner, does not need temporarily from clear
It is clean, it is reminded without automatically cleaning, control indoor unit continues to run t* (A/A1-1) after the time, and the operation of air conditioner time has reached at this time
To t*A/A1, no longer do the multilevel iudge of above-mentioned input current value A1 and standard current value A, directly issue characterization air-conditioning need into
The self-cleaning prompt information of row, to remind user to clean air-conditioning.
Preferably, after issuing characterization air-conditioning and needing to carry out self-cleaning prompt information, automatically cleaning detection time t is repaired
It is just t1, wherein t1=t*A/A1.When input current value A1 is greater than standard current value A, illustrate to detect it in this automatically cleaning
Before, air-conditioning, which has reached, needs self-cleaning degree, it is therefore desirable to the interval time for shortening next automatically cleaning detection, t1 is arranged
For t*A/A1, since A1 is greater than A, then t1 is less than t, therefore next automatically cleaning detection time is less than this automatically cleaning detection time,
Adjustment amount when specific amendment also not chooses at random, but after considering standard current value A and indoor fan input current value A1
The selection of progress is improved using standard current value A and indoor fan input current value A1 as the control variable of modified adjustment amount
Modified accuracy.When input current value A1 is less than or equal to standard current value A, illustrate when this automatically cleaning detects, it is empty
It adjusts and also not up to needs self-cleaning degree, it is therefore desirable to the interval time for extending next automatically cleaning detection, equally t1 be arranged
For t*A/A1, since A1 is less than or equal to A, then t1 is less than or equal to t, therefore next automatically cleaning detection time is more than or equal to this from clear
Clean detection time.In the above-described embodiment, automatically cleaning detection time is corrected, that is to say, that initial automatically cleaning inspection
Surveying the time can be with built in air-conditioning system or user is configured, after initial automatically cleaning detection time determines, primary detection
Current air conditioner indoor unit adds up operation duration and is subject to the initial cleanness detection time, later, accumulative to current air conditioner indoor unit
In deterministic process when operation duration meets automatically cleaning detection time, before primary revised automatically cleaning detection time conduct
This carries out indoor unit and adds up the basis that operation duration meets automatically cleaning detection time.The present invention carries out automatically cleaning detection time
Amendment, so that present invention judgement self-cleaning for air-conditioning is more in line with specific use environment, judging result is also more just
Really.
In the above-described embodiment, primary to whether needing automatically cleaning to carry out in air-conditioning by setting automatically cleaning detection time
Whether judgement needs automatically cleaning to carry out two when air-conditioner operation time meets the automatically cleaning detection time of setting into air-conditioning
Secondary judgement, when whether needing automatically cleaning to carry out secondary judgement in air-conditioning, provided with for detecting whether air-conditioning needs automatically cleaning
Detection wind speed, obtain input current value of the air-conditioning indoor fan when operating under automatically cleaning detects wind speed, and by input current
Value standard current value corresponding with automatically cleaning detection wind speed is compared, and is whether air-conditioning needs automatically cleaning with determination.This control
Mode processed can efficiently solve the problem that the self-cleaning judgment method of air-conditioning is not smart enough in the prior art, make air-conditioning according to certainly
Body clean-up performance intelligently judges the opportunity into automatically cleaning mode, ensures the good operating status of air-conditioning.
Another optional embodiment according to an embodiment of the present invention, according to comparison result determine air-conditioning whether needs
After automatically cleaning, further include：In response to the self-cleaning control instruction of permission air-conditioning of triggering, controls air-conditioning and enter automatically cleaning operation
Mode；Under automatically cleaning operational mode, control air-conditioning is opened built-in sprayer and is humidified, and controls air-conditioning low lower than presetting
Refrigerating operaton preset duration T is persistently carried out in the case of pressure x.Frosting is carried out due to needing to control evaporator when air-conditioning automatically cleaning, and
Evaporating pressure and air-conditioning humidity can all influence frosting velocity, and then influence the energy consumption of heat pamp and air-conditioning.Therefore, in order to make
Faster, the present invention, which is provided with, is located at indoor machine evaporation side, for increasing the spraying device of air humidity, by opening for air-conditioning frosting
Spraying device is opened, and controls indoor unit lower than refrigerating operaton preset duration T is persistently carried out in the case of pre-set low pressure x, not only may be used
To be humidified to indoor, evaporimeter frosting can also be accelerated, to accelerate automatically cleaning.
Yet another alternative embodiment according to an embodiment of the present invention, according to comparison result determine air-conditioning whether needs
After automatically cleaning, if user has found that evaporator is not dirty, skip without automatically cleaning, then system does not trigger in confirmation allows air-conditioning certainly
When clean control instruction, processing is marked, automatic accumulative label number of processes is marked if label number of processes is more than n times
When the quantity of note processing meets default value, forces air-conditioning to enter automatically cleaning operational mode, do not clean sky for a long time to avoid user
It adjusts, causes running state of air conditioner bad.
Yet another alternative embodiment according to an embodiment of the present invention, to prevent user from skipping warning, unclear washed filter
Net, or system alert is not responded for a long time, system also proceeds as follows after reminding user：After reminding user,
Every default automatically cleaning acknowledging time (such as 12 hours), judge whether air-conditioning has executed automatically cleaning operation, specifically, interval
Default automatically cleaning acknowledging time (such as 12 hours) reacquire input current of the indoor fan by automatically cleaning detection wind speed operating when
Whether value A1 has executed automatically cleaning to air-conditioning according to the comparison result of the input current value A1 of reacquisition and standard current value A
Operation is judged, wherein when the input current value A1 of reacquisition is greater than standard current value A, determines that air-conditioning is not carried out certainly
Clean operation, otherwise, it is determined that air-conditioning has executed automatically cleaning operation.When determining that air-conditioning has executed automatically cleaning operation, air-conditioning is controlled
It remains in operation according to each default value of laststate, that is, after needing preceding primary sending air-conditioning to carry out self-cleaning prompt information
Revised cleaning detection time is as new cleaning detection time, when detecting the accumulative operation of the air conditioner indoor unit again
Between, and when the accumulated running time reaching revised cleaning detection time, judge whether the air-conditioning needs to clean.?
When determining that air-conditioning is not carried out automatically cleaning operation, adjusts and determine whether air-conditioning needs self-cleaning prompting frequency, including：At interval of pre-
If the time (such as at interval of 48 hours) detects input current value A1, and the input current value A1 and standard electric that will be detected again again
Flow valuve A is compared, and determines whether air-conditioning needs automatically cleaning, until after confirmation air-conditioning has executed automatically cleaning operation.In order to embody
In the case where not carrying out cleaning air conditioner to user, the thought for reminding frequency is improved, when preset time at this time is less than laststate
Modified automatically cleaning detection time, with improve air-conditioning automatically cleaning detection frequency and remind user enter automatically cleaning mode
Frequency makes air-conditioning be in clean state until completing automatically cleaning.
Another air-conditioning automatically cleaning control method is provided in the preferred embodiment of the invention 1.Fig. 2 shows this method
A kind of optional flow chart, as shown in Fig. 2, this method includes：
Evaporator is cleaned, low pressure duration is maintained to be defaulted as T, the interior machine accumulation available machine time is defaulted as t, and interior machine air-supply is specific
It is A that revolving speed, which defaults current value,.
After interior machine is switched on time duration arrival time t, interior machine transfers wind, starts a certain specific rotation speeds, it is specific to obtain this
Motor input current A value under revolving speed, quantification stability runing time motor input current value A1.
If A1 > A, an initial cumulative time t1 is defaulted as t*A/A1 under interior machine.And it is used by manual operator or mobile phone reminding
Filter screen is cleaned at family, prompts whether to need to be evaporated device cleaning automatically.
If A1 < A, an initial cumulative time t1 is defaulted as t*A/A1 under interior machine, and unit does not enter prompting, directly on the basis t
On continue to be accumulated to t*A/A1, then carry out prompting user, do not do and judge again.
It, can be in practical implementation it should be noted that do not provide execution logic when A1=A in Fig. 2
Execution logic when according to demand by A1=A is divided into the corresponding execution logic of A1 > A or is divided into the corresponding execution logic of A1 < A.
If user allows evaporator to clean, built-in sprayer is opened, and is humidified, system operation refrigeration, continuous service
Lower than low pressure x duration T.
If user has found that evaporator is not dirty, skip and cleaned without evaporator, then the automatic cumulative number of system, if number is super
N times are crossed, then are cleaned automatically.
System alert is not responded to prevent user from skipping warning, unclear washed strainer, or long-time, system is reminding use
Behind family, accumulative operation 12h detects motor present input current value, i.e. Ao value again, and Ao value and specific rotation speeds are defaulted current value
It is compared for A.
If Ao > A value, system current default laststate filter screen does not clean yet, with 48h/ prompting user's indoor unit
Filter screen clean level simultaneously detects current Ao value, once user cleans filter screen, then cancels system alert, adds up timing again,
Respectively it is worth with laststate for default value.
If Ao < A value, system current default laststate filter screen is processed, is respectively worth with laststate for default value,
Continue accumulative timing and runs.
In the above-described embodiment, automatically cleaning whether is needed once to be sentenced in air-conditioning by air-conditioning internal machine runing time
It is disconnected, when air-conditioner operation time meets setting condition, whether need automatically cleaning to carry out secondary judgement into air-conditioning, to air-conditioning
