Detailed description of the invention
Be described principle of the present invention and feature below in conjunction with accompanying drawing, example, only for explaining the present invention, is not intended to limit scope of the present invention.
Embodiment one, a kind of method judging internal machine of air-conditioner filter screen laying dust.Below in conjunction with Fig. 1, the method that the present embodiment provides is described in detail.
See Fig. 1, S1, when air-conditioner start is tried out, the operate power P1 of record blower fan when different windscreen gear runs
i, i is positive integer, and the value of i is 1 ... N, represents different windscreen gears.
Concrete, in the present embodiment, the interior machine of air-conditioning is DC fan, and when user sets a specific rotating speed, the control assembly of blower fan can by having regulated the constant of rotating speed automatically.And when running under accumulative laying dust, along with the increase of laying dust thickness, the resistance of blower air flowing also can strengthen, and under blower fan wants to maintain this rotating speed, its power output will inevitably be increased, therefore, the present embodiment can adopt the change of fan operation power to judge the laying dust situation of air-conditioning internal machine filter screen.Therefore, when air-conditioner start trial run, record the operate power P1i of blower fan when each different windscreen gear runs, wherein, i is positive integer, and the value of i is 1 ... N, i represent different windscreen gears.Such as, air-conditioner is corresponding four kinds of windscreen gears usually, are respectively superelevation windscreen, high windscreen, middle windscreen and low windscreen, respectively superelevation windscreen can be 1 windscreen, high windscreen is 2 windscreens, middle windscreen is 3 windscreens, low windscreen is 4 windscreens.
S2, when air-conditioner start runs after the scheduled time reaches normal operation, the current operate power P2 of blower fan is detected at interval to schedule
i, check the current residing windscreen gear i of described blower fan simultaneously.
S3, the current operate power P2 of described blower fan detected when air-conditioner is normally run
ithe fan operation power P 1 of corresponding windscreen gear when trying out to air-conditioner
icompare, work as P2
i/ P1
iwhen being more than or equal to first threshold, in prompting, machine filter net needs dedusting; Work as P
