The second PWM duty cycle answered, and/or, judge whether the first electric current is greater than corresponding second electric current of nominal air delivery of air-conditioning draught fan,
In the case where the judgment result is yes, control cleaning device 18 cleans air-conditioning to further controller 16, and having reached makes operation of air conditioner
When the purpose that reduces of static pressure, to realize the technical effect of most stable of air quantity output, and then solve due to filter screen
Easily it is dirty it is stifled caused by the unstable technical problem of air conditioning exhausting.
Preferably, acquisition device 12 can be also used for cleaning air-conditioning in control cleaning device 18, quiet when making operation of air conditioner
After pressure reduces, the third PWM duty cycle and/or third electric current of air-conditioning draught fan are acquired；Processor 14 can be also used for acquisition

I.e. after cleaning device 18 cleans air-conditioning, acquisition device 12 acquires air-conditioning draught fan feedback again
PWM duty cycle value and/or electric current, as above-mentioned third PWM duty cycle and/or third electric current, processor 14 by the value again
The second PWM duty cycle corresponding with the nominal air delivery of air-conditioning draught fan and/or the second electric current compare, if the difference of the two is smaller
Then illustrate that the air quantity adjusted after cleaning and nominal air delivery difference are smaller negligible, and then air-conditioning draught fan continues by after cleaning
Revolving speed operation illustrates that the air quantity adjusted after cleaning and nominal air delivery still have certain gap, Jin Ertong if the difference of the two is larger
Cross the mode that controller 16 is adjusted the revolving speed of air-conditioning draught fan, control air-conditioning draught fan adjustment air output is to reaching specified wind
Amount.
Further, controller 16 may include: the first control module, for being greater than second in third PWM duty cycle
PWM duty cycle, and/or, in the case that third electric current is greater than the second electric current, by improving the control mode of rotating speed of air conditioner fan,

Preferably, cleaning device 18 can be electrostatic precipitation module, and electrostatic precipitation module is by way of Electrostatic Absorption pair
The strainer of air-conditioning is cleaned.
Meanwhile controller 16 is also used to carry out cleaning to the strainer of air-conditioning by control electrostatic precipitation module to make operation of air conditioner
When static pressure reduce.
In air-conditioning actual moving process, the real-time PWM duty cycle and electric current of air-conditioning draught fan and the hollow allocation and transportation of local environment
Static pressure when row is related, and environment temperature and windage size are to influence two key factors of static pressure.In environment temperature one
In the case where fixed, the more big then static pressure of windage is bigger, and then keeps real-time PWM duty cycle and electric current bigger, and then can control output more
Big revolving speed.Therefore air conditioner filter screen it is dirty it is stifled after, the real-time PWM by influencing windage effect static pressure, and then when influencing operation of air conditioner is accounted for
Empty when electric current, and then influence the revolving speed and air quantity of air-conditioning draught fan.Under constant installation environment, ideal air-conditioning effect
I.e. in the case where strainer does not have situation dirty plugging, the corresponding air conditioning exhausting amount of each gear is fixed value, i.e. nominal air delivery, to guarantee
Air conditioning exhausting amount reaches fixed value, and when air-conditioner set is dirty stifled, that is, in the case of having windage, air-conditioning draught fan needs discharge quantity of fan to increase,
And then revolving speed increases, and then when electric current also increases the real-time PWM duty of influence air-conditioning draught fan.Therefore this optimal technical scheme is logical
The size for crossing the corresponding PWM duty cycle of comparison nominal air delivery and/or electric current and real-time PWM duty cycle and/or electric current, automatically controls
Electrostatic precipitation module is that the strainer of air-conditioning is cleaned, and reduces static pressure when operation of air conditioner, and then the wind of air-conditioning draught fan output
It measures constant for nominal air delivery.Wherein, above-mentioned cleaning device 18 can be electrostatic precipitation module, to sky by way of Electrostatic Absorption
The strainer of tune is cleaned, or can be other devices that air conditioner filter screen is dusted.
Because the static pressure of operation of air conditioner in varying environment is different, therefore to reach the nominal air delivery under each gear, system may be used also
To include: detector, for when air-conditioning initial power-on starts, acquisition device 12 to acquire the first PWM duty ratio of air-conditioning draught fan
And/or first before electric current, obtains the environmental parameter of the environment of air-conditioning installation；Wherein, processor 16 is also used to be joined according to environment
Number determines that air-conditioning draught fan operation reaches the revolving speed of nominal air delivery；Controller 18 is also used to control air-conditioning draught fan with determining revolving speed
Operation.
Wherein, it should be noted that above-mentioned air-conditioning draught fan is used to export the air quantity of air-conditioning, and the control algolithm of use is to pass through
Motor speed is adjusted to export certain duty ratio, corresponding voltage is exported by duty ratio and is adjusted the speed.Air-conditioning draught fan
Duty ratio depends on its gear, works as ceteris paribus, changes air-conditioning draught fan gear, then corresponding variation occurs for its duty ratio,
And then its air quantity changes.
The duty ratio of air-conditioning draught fan is other than depending on gear simultaneously, and there are also the environmental parameters of air-conditioning local environment, such as
Environment temperature, atmospheric pressure etc..Environmental parameter influences the duty ratio in air-conditioning draught fan operational process, so, when air-conditioning is initially opened
When machine is run, for different environmental parameters, the static pressure of operation of air conditioner is different, for the output for reaching nominal air delivery, needs the sky
Revolving speed when control system being adjusted to determine that air-conditioning draught fan reaches nominal air delivery in this context according to different environment, by the adaptation
Property adjust after, air-conditioning draught fan with the revolving speed operation, export constant nominal air delivery.
Fig. 2 is the structure according to the permanent wind amount control system based on strainer self-cleaning of the utility model preferred embodiment
Schematic diagram, as shown in Fig. 2, the permanent wind amount control system includes: detector 22, processor 24, controller 26, electrostatic precipitation module
28.The permanent wind amount control system is described in detail below.
Air-conditioning first powers on operation, and strainer is completely new clean state at this time, for different installation environments, operation of air conditioner
When static pressure it is different, for the output for reaching constant wind quantity, so needing to determine that air-conditioning draught fan is finally run according to different environment
Tachometer value.
Specifically, unified with the operation of initial fixed rotating speed when opening for air-conditioning draught fan, it is real that detector 22 detects air-conditioning draught fan
When the PWM duty cycle value fed back or electric current, processor 24 by the value with when nominal air delivery PWM duty cycle and current value compare
Compared with when the PWM duty cycle value or larger electric current of feedback, controller 26 improves the revolving speed of air-conditioning draught fan operation, as the PWM of feedback
When dutyfactor value or smaller electric current, controller 26 reduces the revolving speed of fan operation, and then reaches specified air quantity.
Then, when blower is brought into operation with nominal air delivery, with the increase of air conditioning usage time, the strainer of air-conditioning can be gradually
Dirty, static pressure increases, at this time since revolving speed is fixed, so the air output of air-conditioning is caused to reduce, the PWM duty that blower is fed back at this time
Ratio or electric current will increase at this time, when detector 22 detects that the PWM duty cycle value of blower or electric current start to increase, controller 26
Automatic starting electrostatic precipitation module 28, starts to clean strainer, and after cleaning, detector 22 again feed back by detection blower fan
PWM duty cycle value or electric current, processor 24 compares the value with initial current value again, if the difference of the two is smaller
Then controller 26 controls blower and still presses the operation of revolving speed at this time, if the difference of the two is larger, controller 26 will improve blower again
The revolving speed of operation, the operation of blower continued for constant air quantity.
Above-mentioned permanent wind amount control system has carried out the related key factor that changes to influence air quantity --- air-conditioning filter
The control of net, because air-conditioning air volume can with strainer it is dirty it is stifled respond immediately, therefore the system realizes and intelligent carries out cleaning filter
Net adjusts revolving speed, to reach constant ideal air quantity.In order to which the strainer of air-conditioning can be cleaned in real time, increase in the front end of strainer
Add electrostatic precipitation module 28, therefore in the system operation, to realize that permanent wind amount is adjusted, as blower feeds back PWM duty cycle value
Or the change of electric current, filter screen can be automatically cleaned at any time by electrostatic precipitation module 28.
Therefore to sum up, the utility model preferred embodiment utilizes the PWM duty cycle value or electric current of air-conditioning draught fan actual feedback
With the fiducial value of rated value, inner blower air quantity is adjusted jointly by cleaning strainer, when detector 22 detects that the PWM of blower is accounted for
When empty ratio or electric current change, electrostatic precipitation module 28 cleans strainer again, to reach a constant discharge quantity of fan,
The most stable of air quantity output of air-conditioning draught fan is realized, number and time that user cleans strainer are decreased.
