The control method of air conditioner according to embodiments of the present invention is described below with reference to Fig. 1.
The control method of air conditioner according to embodiments of the present invention, as shown in figure 1, comprising the following steps：
S1：Detect the real-time pulse width of the motor 1 of air conditioner.Specifically, motor 1 can be DC brushless motor.
S2：The pulse width detected and the absolute difference of the initial pulse width of motor 1 are compared with given threshold
Compared with.In one embodiment of the invention, can using microcontroller 2 perform step S1 and step S2, now, microcontroller 2 with
Motor is electrically connected, after the indoor set of air-conditioning is opened, and the pulse that microcontroller 2 is automatically real-time read when interior motor 1 is operated is wide
Degree, at the same microcontroller 2 by the absolute difference of the pulse width detected in real time automatically and the initial pulse width of motor 1 with setting
Determine threshold value to be compared.
What deserves to be explained is, the initial pulse width of motor 1 is that air conditioner room unit dirt filtrating screen is in initial clean shape
The pulse width of motor 1 during state.The initial pulse width of motor 1 can be measured in advance, and be stored in microcontroller 2.Can
With understanding, fans load change and rotation speed of fan change can cause the change of pulse width.Internal machine of air-conditioner dirt filtrating screen
The dirty stifled state of dust stratification is converted to by clean state, its air output can be caused to decline, i.e., fans load reduces, so as to cause motor
Pulse width is reduced, and the pulse width at this moment detected will have an absolute difference with the initial pulse width of motor 1.If
Determine threshold value to obtain by laboratory facilities.
It is understood that under some rotating speed of motor 1, can measure dirt filtrating screen by experiment and be turned by clean state
Width parameter during dirty stifled state is faded to, width parameter includes the range of decrease of initial pulse width and pulse width, and pulse is wide here
The range of decrease of degree namely sets threshold values.That is, by the absolute of the pulse width detected and the initial pulse width of motor 1
Difference by testing obtained given threshold with being compared, when absolute difference is more than or equal to setting threshold values, air conditioner micro-control
Device 2 processed think indoor set dirt filtrating screen occur the dirty stifled phenomenon of dust stratification, that is, air conditioner room unit it is dust-full.
Certainly, the range of decrease of the pulse width under different rotating speeds can be also measured by laboratory facilities, that is, under different rotating speeds
Setting threshold values.
For example, when air conditioner dust filter gauze clean state, indoor fan rotating speed are certain rotating speed, it is assumed that indoor fan motor 1 is transported
The pulse width turned is C0；Gradually accumulated with dust on dirt filtrating screen, indoor fan loads less and less, indoor fan motor 1
The pulse width range of decrease of operating（Namely set threshold values）For DET_C.Microcontroller 2 is by the pulse width detected in real time automatically
C and the initial pulse width C0 of motor 1 absolute difference（C0-C）With given threshold（DET_C）It is compared.Work as absolute difference
More than or equal to given threshold, air conditioner microcontroller 2 thinks that the dirty stifled phenomenon of dust stratification, that is, air conditioner occur for indoor set dirt filtrating screen
Indoor set is dust-full.
Specifically, when air conditioner dust filter gauze clean state, indoor fan rotating speed are 1200rpm, it is assumed that indoor fan motor 1
The pulse width of operating is C01；Gradually accumulated with dust on dirt filtrating screen, inner blower load is less and less, equally wind indoors
When the rotating speed of machine is 1200rpm, the pulse width range of decrease that indoor fan motor 1 is operated（Namely set threshold values）For DET_C1.
Microcontroller 2 is by the pulse width C detected in real time automatically and the initial pulse width C01 of motor 1 absolute difference（C01-C）
With given threshold（DET_C1）It is compared.When absolute difference is more than or equal to given threshold, air conditioner microcontroller 2 thinks indoor
The machine dirt filtrating screen generation dirty stifled phenomenon of dust stratification, that is, air conditioner room unit are dust-full.
Similarly, during blower fan setting speed 1000rpm, dirt filtrating screen is converted to dirty stifled state, indoor fan electricity by clean state
The initial value for the pulse width that machine 1 is operated is C02, its range of decrease（Set threshold values）For DET_C2.Microcontroller 2 will be detected in real time automatically
The pulse width C arrived and the initial pulse width C02 of motor 1 absolute difference（C02-C）With given threshold（DET_C2）Carry out
Compare.When absolute difference is more than or equal to given threshold, it is dirty stifled existing that air conditioner microcontroller 2 thinks that dust stratification occurs for indoor set dirt filtrating screen
As, that is, air conditioner room unit it is dust-full.
It is understood that by laboratory facilities, can measure under more different rotating speeds, dirt filtrating screen is converted to by clean state
Width parameter during dirty stifled state（Including initial pulse width and setting threshold values）, so can be obtained by any rotation speed of fan
Under the conditions of judge the threshold pulse width parameter whether dirt filtrating screen blocks, and initial pulse width and setting threshold values are stored in microcontroller
Device 2.
S3：When absolute difference is more than or equal to given threshold, the warning device 3 of control air conditioner is alarmed, and works as absolute difference
During less than given threshold, step S1 is returned to.That is, when absolute difference is more than or equal to given threshold, air conditioner microcontroller 2
Think indoor set dirt filtrating screen occur the dirty stifled phenomenon of dust stratification, that is, air conditioner room unit it is dust-full, at this moment controller 2 control air conditioner
Warning device 3 alarm to remind user to clear up dust in time.When absolute difference is less than given threshold, air conditioner microcontroller 2
Think that indoor set dirt filtrating screen is clean, do not occur the dirty stifled phenomenon of dust stratification, at this moment controller 2 continues to detect the motor 1 of air conditioner
Real-time pulse width, and the pulse width detected and the absolute difference of the initial pulse width of motor 1 are entered with given threshold
Row compares, that is, returns in step S1 and detect the real-time pulse width of motor 1 again, so repeats.
That is, when motor 1 runs work under a certain determination rotating speed, microcontroller 2 judges the motor 1 detected in real time
Whether the absolute difference of pulse width and the initial pulse width of the motor 1 under the rotating speed is more than the setting threshold values under the speed.
When absolute difference is more than or equal to setting threshold values, the control work alarm of warning device 3 of controller 2, when absolute difference is less than setting
During threshold values, warning device 3 does not work alarm.
It is, of course, understood that on user's cleaning dirt filtrating screen after dust stratification, air conditioner microcontroller 2 is detectable real-time
Pulse width, range of decrease threshold value of the difference less than setting of itself and initial pulse width, is now then turned on air conditioner, warning device 3
To no longer be worked prompting.
The control method of air conditioner according to embodiments of the present invention, pulse during by detecting that the motor 1 of air conditioner is operated
Width, and when being operated according to indoor fan motor 1 pulse width change, by the initial arteries and veins of the pulse width of detection and motor 1
The absolute difference and given threshold for rushing width are compared, and then may determine that whether dirt filtrating screen occurs the dirty stifled phenomenon of dust stratification, and
Alarmed in the dirty stifled phenomenon of generation dust stratification to user, practicality is good.
