Specific embodiment
As depicted in figs. 1 and 2, a kind of stifled situation automatic testing method of idle call filter screen dirtying is provided, the air-conditioning includes:
Evaporator 5, pedestal 6, air outlet 7, through-flow fan blade 8 and filter screen 2, which is characterized in that 2 side of filter screen is provided at least
One photosensitive sensor 4, the other side are provided at least one illuminator 3, and the automatic testing method includes the following steps: S1:
Air-conditioning 1 powers on, and illuminator 3 must be electric, and photosensitive sensor 4 detects current light intensity, is denoted as initial beam intensity λ 1；S2: detection current light intensity
λ, judges whether current light intensity λ is greater than λ 1；If it is not, executing step S3；Whether S3: detection current light intensity λ judge current light intensity λ
Less than (λ 1-N1)；If so, issuing dirty stifled warning reminding, step S4 is executed；S4: detection current light intensity λ judges that current light intensity λ is
It is no to be greater than (λ 1-N2)；If so, removing dirty stifled warning reminding.
The present invention judges whether the filter screen 2 of air-conditioning 1 occurs dirty stifled or mistake by detecting the luminous intensity through filter screen 2
The cleaning situation of strainer 2.In use due to air-conditioning 1, dust and other impurities can deposit constantly at filter screen 2, make
The luminous intensity obtained through filter screen 2 can also decay therewith, so, the dirty stifled situation of filter screen 2 is different, through the light of filter screen 2
Intensity can also change accordingly.Therefore, can by 2 side of filter screen be arranged at least one photosensitive sensor 4 come
It detects filter screen 2 and penetrates light intensity decays situation, and filter screen 2 is judged through light intensity decays situation by filter screen 2
Dirty stifled situation just issues the dirty stifled warning reminding of filter screen 2 to user after through light intensity decays to a certain extent, and works as and use
After filter screen 2 is cleaned at family, relatively high level can be restored through the luminous intensity of filter screen 2, by saturating after cleaning
The luminous intensity for crossing filter screen 2 is detected, can the cleaning situation to filter screen 2 detected automatically.
Specifically, it is contemplated that under the conditions of natural lighting, luminous intensity and time, environment and weather through filter screen 2 etc. because
Element has relationship, therefore the dirty stifled situation of filter screen 2 is unable to judge accurately under the conditions of natural lighting.Therefore, photosensitive on filter screen 2
At least one illuminator 3 is arranged in the opposite side of sensor 4, and the illuminator 3 can be light emitting diode, fluorescent lamp, incandescent lamp, halogen
One of tungsten lamp or gas-discharge lamp or their combination.By the way that illuminator 3 is arranged, photosensitive sensor 4 is examined
Measure the light source of constant brightness.
The i.e. described detection method step S1 are as follows: air-conditioning (1) powers on, and illuminator (3) must be electric, and photosensitive sensor 4 detects currently
Light intensity is denoted as initial beam intensity λ 1.
More specifically, after executing the step S1, it is contemplated that the fluctuations such as electric current when equipment starts in start process
Minor way after powering in a period of time T1, confirms initial beam intensity λ 1, to improve accuracy in detection and precision,
Reduce rate of false alarm.If current light intensity λ continues to be greater than within T1 minutes λ 1, electricity when initial beam intensity λ 1 receives the starting of start process equipment
The minor way of the fluctuations such as stream, need to be updated to current light intensity λ for 1 value of initial beam intensity λ, conversely, then without being updated.
The i.e. described step S2: detection current light intensity λ judges whether current light intensity λ is greater than λ 1；If it is not, executing step S3.Tool
Body, the step S2 includes: detection current light intensity λ, and current light intensity λ and initial beam intensity λ 1 are compared；If current light
Strong λ continues to be greater than λ 1 in T1 minutes, then 1 value of λ is updated to current light intensity λ, executes step S2 again；S23: if current light intensity λ is held
It is not more than initial beam intensity λ 1 within continuous T1 minutes, executes step S3.
Further, in 1 use process of air-conditioning, since dust and other impurities constantly deposits at filter screen 2, so that
The current light intensity λ that photosensitive sensor 4 can detecte decays therewith, therefore, can preset the dirty stifled alarm valve an of filter screen 2
Value, the dirty stifled alarming threshold value are whether filter screen 2 occurs judgment basis dirty plugging, to improve accuracy in detection, in a timing
Between carry out in T2 continuing detection, when in certain time interval T 2 current light intensity λ continuously less than the setting dirty stifled alarming threshold value when, sentence
It is set to filter screen 2 and dirty block up occurs；When current light intensity λ is persistently not less than the dirty stifled alarming threshold value of the setting in certain time interval T 2
When, then filter screen 2 does not occur dirty stifled, it is contemplated that the fluctuation of equipment running process executes step S2 again, to initial beam intensity λ 1 into
Row is reaffirmed.
Further, net 2 is filtered generally by one fixed dirty stifled alarming threshold value of setting in the prior art
Dirty stifled situation judgement, the dirty stifled alarming threshold value of the fixation are generally relatively low.For the air-conditioning just to have come into operation, for more
It is that user provides a healthy environment, while also providing a more excellent operating status for air-conditioning, at this point it is possible to set
One relatively high dirty stifled alarming threshold value is filtered the dirty stifled situation judgement of net 2, i.e., has not occurred in filter screen 2 serious dirty stifled
When, dirty stifled alarm is just issued the user with, user is reminded to clean filter screen 2.And with the growth of 1 runing time of air-conditioning, even if through
Carefully cleaning is crossed, remaining in the impurity being difficult to clean off at filter screen 2 also will be inevitably more and more.At this point, if dirty stifled report
Alert threshold value setting is still higher, and air-conditioning 1 will frequently issue the user with dirty stifled alarm in the process of running, and user is reminded to clean filtering
Net 2 will affect user's use.In view of problem above, to provide a user a more humanized dirty stifled alarm scheme, this
Invention provides a kind of as filter screen usage degree is deepened, the dirty stifled alarming threshold value that can be gradually decreased.The present invention is by dirty stifled alarm
Threshold value setting is (λ 1-N1), wherein N1 is a preset value.In 2 use process of filter screen, by the dynamic of initial beam intensity λ 1
State updates, so that dirty stifled alarming threshold value (λ 1-N1) can be gradually decreased with the intensification of 2 usage degree of filter screen, realizes dirty
The dynamic adjustment of stifled alarming threshold value (λ 1-N1).
The i.e. described step S3: detection current light intensity λ judges whether current light intensity λ is less than (λ 1-N1)；If so, issuing dirty stifled
Warning reminding executes step S4.Specifically, the step S3 includes: detection current light intensity λ, and by current light intensity λ and (λ 1-
N1 it) compares, if current light intensity λ continues T2 minutes not less than (λ 1-N1), dirty stifled, execution step does not occur for filter screen 2
S2 again confirms initial beam intensity λ 1；If current light intensity λ continues to be less than (λ 1-N1) in T2 minutes, it is judged as filter screen 2
It is dirty stifled, the dirty stifled warning reminding of filter screen 2 is issued, user is reminded to clean filter screen 2, executes step S4.
Further, after user cleans filter screen 2, need to the cleaning situation to filter screen 2 detect really
Recognize, to ensure that the clean condition of filter screen 2 has been restored to a higher level, avoids since cleaning is not thorough for a long time for filter screen 2
Bottom, so that remaining the more impurity being difficult to clean off on filter screen 2.It is once purged, filter screen 2 can be restored to one it is relatively high
Level, at this point, a clean threshold values can be set, the cleaning threshold values is the judgment basis whether filter screen 2 cleans up.To mention
High detection accuracy carries out continuing detection at one end in time T3, when current light intensity λ is persistently greater than this and sets in certain time interval T 3
When fixed clean threshold values, it was determined as that user was cleaned and finishes strainer 2, and removed dirty stifled alarm；Work as when in certain time interval T 3
When preceding light intensity λ is persistently not more than the clean threshold values of the setting, it is determined as that filter screen 2 is not cleaned or cleaned and is not thorough, continues
The dirty stifled prompting of filter screen 2 is issued the user with, user is reminded to clean filter screen 2.
Similarly, condition detection is cleaned for filter screen, there is also this problems.For the air-conditioning just to have come into operation,
Filter screen 2 is once purged after sending dirty block up, and can be restored to the relatively high state of cleanliness levels, at this point, clean threshold values
It sets relatively high.And with filter screen 2 using the time growth, even if once purged, the cleanliness levels of filter screen 2 also only
Relatively low state can be restored to.At this point, if clean threshold value setting is still higher, air-conditioning 1 in the process of running will frequently to
User issues dirty stifled alarm, and user is reminded to clean filter screen 2, influences user's use.Clean threshold value setting is (λ 1- by the present invention
N2), updated by the dynamic to initial beam intensity λ 1, so that clean threshold values (λ 1-N2) can be with the intensification of 2 usage degree of filter screen
And gradually decrease, the dynamic adjustment of clean threshold values (λ 1-N2) is realized, is effectively limited for the clean-up performance to filter screen 2,
The N2 is a preset value, and N2 should be less than N1, so that clean threshold values (λ 1-N2) is greater than dirty stifled alarming threshold value (λ 1-N1).This
Outside, filter screen 2 is cleaned situation detection it is qualified after, execute step S2, again carry out current light intensity λ and initial beam intensity λ 1 pair
Than so that initial beam intensity λ 1 can be timely updated, and then clean threshold values (λ 1-N2) and dirty stifled alarming threshold value (λ can be adjusted in time
1-N1)。
The i.e. described step S4: detection current light intensity λ judges whether current light intensity λ is greater than (λ 1-N2)；If so, removing dirty stifled
Warning reminding.Specifically, the step S4 includes: detection current light intensity λ, and current light intensity λ and (λ 1-N2) are compared；
If current light intensity λ continues to be greater than (λ 1-N2) in T3 minutes, it is judged as that user is cleaned and finishes filter screen 2, remove filter screen 2
Dirty stifled warning reminding executes step S2；If current light intensity λ continues T2 minutes no more than (λ 1-N2), it is judged as that filter screen 2 is dirty
It is stifled, the dirty stifled warning reminding of filter screen 2 is issued, user is reminded to clean filter screen 2, executes step S4.
Specifically, the dirty stifled warning reminding of the filter screen 2 includes: control buzzer call；And/or on control operation panel
Default indicator light flashing；And/or forbid being switched on.
It can be seen from the above description that the present invention realizes following technical effect:
Compared with traditional technology, the present invention is not simply filtered dirty block up of net 2 using accumulated time by air-conditioning 1 and sentences
It is disconnected, also to judge the dirty stifled situation of filter screen 2 indirectly by other component operating parameter on air-conditioning 1, but directly by setting
It is dirty to carry out to detect the light intensity for the illuminator 3 that 2 other side of filter screen is arranged in set the photosensitive sensor 4 in 2 side of filter screen
Stifled and cleaning situation judgement, not only can be improved the accuracy of the dirty stifled detection of filter screen 2, reduces rate of false alarm, can also be to filtering
The cleaning situation of net 2 is detected.In addition, the present invention carries out area without stifled situation dirty to the filter screen 2 under different operational modes
Do not determine, determination method is simpler.Prior, the present invention can be to detection threshold, such as: clean threshold values (λ 1-N2) and dirty
Stifled alarming threshold value (λ 1-N1) carries out dynamic update, has higher detection accuracy and precision, more human nature can be provided for user
The filter screen dirtying of change is stifled to be reminded.
It should be pointed out that for those of ordinary skill in the art, without departing from the principle of the present invention, may be used also
With several improvements and modifications are made to the present invention, these improvements and modifications also fall within the scope of protection of the claims of the present invention.
