Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
The invention provides the dirty stifled detection method of a kind of air-conditioner.
With reference to the flow chart that Fig. 1, Fig. 1 are dirty stifled detection method first embodiment of air-conditioner of the present invention.
The dirty stifled detection method of air-conditioner comprises:
Step S10, obtains the current operate power of motor of air conditioner.
In the running of air-conditioning, can be heat, to freeze or in air-supply process, after receiving the sense command of user, or after dirty stifled measuring ability opened automatically by machine, start the detection carrying out current motor power, obtain the current operate power of motor of air conditioner, wherein power of motor detection method is prior art, does not repeat them here.
With reference to shown in Fig. 2, step S10 comprises following refinement step:
Step S101, controls described motor of air conditioner and runs preset duration according to preset rotation speed, and in described preset duration the operate power of motor described in timing acquiring.
When detecting power of motor, motor can be forced to run with a default high rotating speed, this rotating speed can be high wind shelves, all more rational in the range of speeds of 900-1400RPM, wind guide strip angle runs to a dirty stifled detection composed view, preferably can be set to the standard angle under refrigeration mode, heating mode or air supply pattern, also can set any one composed view in wind guide strip hunting range.
The rotating speed that such as can be preset as 1200RPM runs, and preset a duration, the operate power of timing acquiring motor in this duration, such as, can be arranged in 15 seconds simultaneously, within every 3 seconds, gathers the operate power of a motor.This rotating speed, duration etc. preset can be arranged according to demand, and this is not restricted.
Step S102, averages to the described operate power got, and using the current operate power of described mean value as described motor of air conditioner.
Air-conditioner was gathered the operate power of a motor for every 3 seconds at 15 seconds, averaged by collect 5 power of motor numerical value, the current operate power of the motor calculated like this is more accurate.
Step S20, the current dirty stifled degree of the screen pack of air-conditioner according to the described current operate power got, default normal motor power and default dirty stifled motor power calculation.
The normal motor power P max stored is the lower limit that normal motor power can be detected when user uses for the first time after this air-conditioner dispatches from the factory, and this value is by the actual installation of analog subscriber and the end value that draws after using.The dirty stifled power of motor Pmin stored be screen pack occur dirty stifled time, reach the higher limit of dirty stifled power of motor when needing cleaning state, this value is also by the actual installation of analog subscriber and the end value that draws after using.
Such as: when air-conditioner dispatches from the factory, the model machine choosing some carries out the various installation environment testing of electric motors performance numbers of analog subscriber, and the power of motor value of test is respectively:
18.02W、18.00W……18.08W、19.05W……
The lower limit Pmax=18W of this machine normal motor performance number can be determined by reality test.
In like manner, the dirty stifled power of motor value of testing when filter screen dirtying blocks up is respectively:
10.50W、9.90W……10.06W、9.00W……
The higher limit Pmin=10.50W of the dirty stifled power of motor of this machine is determined by reality test.
The higher limit Pmin=10.50W of the lower limit Pmax=18W of the normal motor performance number of acquisition and dirty stifled power of motor is preset in air-conditioner.
After getting current operate power Pnow, according to the normal motor power P max of storage and the dirty stifled power of motor Pmin of storage, and formula:
P＝(Pmax-Pnow)/(Pmax-Pmin)*100％
Calculate the dirty stifled degree P of current filter net, the P value calculated is a percentage, and dirty stifled degree P value reality can reflect and the dirty stifled degree that this air-conditioner is current facilitate user to understand air-conditioning situation really.

Calculate the dirty stifled degree P of current filter net, according to P=(Pmax-Pnow)/(Pmax-Pmin) * 100%, with the current operate power Pnow=18.60W detected, calculate dirty stifled degree:
P=(18.60-18.60)/(18.60-10.50) * 100%=0%; I.e. dirty stifled degree P=0%.
Such as, air-conditioner uses through long in the place that dust is larger, has occurred the situation of the current operate power Pnow=9.0W of motor detected, now dirty stifled power of motor value Pmin will be modified to 9.0W and preserve.According to P=(Pmax-Pnow)/(Pmax-Pmin) * 100%, with the current operate power Pnow=9.0W detected, calculate dirty stifled degree
P=(18.60-9.0)/(18.60-9.0) * 100%=100%; I.e. dirty stifled degree P=100%.
