Specific embodiment
The invention will be further described with embodiment with reference to the accompanying drawing.
As shown in figures 1 and 2, air-conditioning filter net dedusting and detection system of the invention, by the automatic inspection based on dust sensor
Examining system and the self-cleaning system of electrostatic precipitation principle composition.
Automatic checkout system: using laser PM2.5 dust sensor, its working principle is that using laser light scattering principle, when
Faint light scattering can be generated near laser irradiation to detection position when the particulate matter of air, scatters to form spectrum by light, from
And the waveform of Spectrum Formation is the number concentration for reflecting real-time particulate matter, sensor detection accuracy is very high, detectable
Small to 0.3 micron of particulate matter diameter, service life reaches 8000 hours.
Laser PM2.5 dust sensor and controller are mounted on air-conditioning outer wall, and laser PM2.5 dust sensor passes through
Air inlet hose is fixed at the air outlet of air-conditioning, timely detection air port fresh air dust content value.
Air conditioner fresh air enters laser PM2.5 dust sensor, laser PM2.5 dust sensor by air induction hose as a result,
Particulate in air is scattered to form light wave, thus the Interior Space that detects indoor air particulate matter concentration, and will test
Aerated particle object concentration parameter signal is transmitted to controller, when parameter values for detection is higher than safety value set by system, controller
Starting warning indicator light lights, while buzzer issues prompt tone and reminds user, and then controller starts self-cleaning system.
Self-cleaning system: it is different from traditional brush scrub, scrub will affect the using effect of strainer repeatedly, cause strainer
The destruction and blocking of fiber.The system uses the replaceable electrostatic precipitation strainer cloth of electrostatic precipitation principle, its working principle is that sharp
With electrostatic fibre electret technology, long service life, each fiber all has high efficiency filter ability on filter cloth, can effectively adsorb
The harmful substances such as dust, dust, pet hair, bacterium, and it is intercepted；Fiber net structure is fluffy, and ventilative performance is strong, using height
Scientific and technological filter material, purifies the air of a room, and the scope of application also very extensively, is applied to wall-hanging air conditioner, integrated air conditioner and vertical
Air-conditioning.The electrostatic strainer for showing every air-conditioning covering 70% according to experiment, that is, can reach and do not increase operation of air conditioner resistance, and energy
Filter quiet effect.
Automatic operating operation is realized in order to liberate both hands, and the mechanical part of self-cleaning system is designed as double automatic reel dresses
It sets, (b), (c) shown such as Fig. 2 (a), double automatic reel devices are simple using double rollings, it is respectively equipped with screw rod 3 in two rollings simple 2,
In screw rod 3 connect motor driver 4 and form driving rolling letter, be wound with electrostatic precipitation strainer on the screw rod 3 of another rolling letter
Cloth 1 forms electrostatic precipitation strainer cloth reel, and electrostatic precipitation strainer cloth reel is placed in air conditioner filter screen side, electrostatic precipitation strainer cloth
1 is covered on air conditioner filter screen from the pull-out of electrostatic precipitation strainer cloth reel, and connect with the screw rod 3 in driving rolling letter.Automatically it is examining
After examining system issues quiet wave signal, dusty old electrostatic precipitation strainer cloth is involved in automatically by motor driver 4
On the screw rod 3 of the driving rolling letter of the other side, to realize the automatic replacement of strainer, when entire volume screen replacing finishes, system refers to
Show that lamp will light for a long time, after reminding a roll of new strainer reel of user's replacement to install, then system is restarted automatically again
It starts to work.Whole system plays Electrostatic Absorption, web intercepts, the purpose to send net wind.
The arrangement of mechanical structure portion, as shown in figures 3 and 4, it is contemplated that the difference of central air-conditioning and wall-hanging air conditioner strainer is special
Set up the following two kinds Installation Modes:
As shown in figure 3, central air-conditioning uses horizontal layout, roller and electrostatic precipitation strainer cloth plane are directly covered on sky
It adjusts and works on strainer.
(b) shown such as Fig. 4 (a), wall-hanging air conditioner arranges that electrostatic precipitation strainer cloth is along air conditioner filter screen radian using curved surface
Curved surface covering, reducing friction resistance guarantee that mechanism operates normally.
Air-conditioning filter net dedusting of the invention and detection system have adjustable air outlet air index safety value, when setting
When emptying the sensor that air filter is connected, user is according to the needs of tradeoff different places and the requirement of system, in App platform
Voluntarily control and set target value, that is, can reach system detection effect, according to different places such as office building, family, market, hospital
Deng according to place clean-up performance and air index parameter setting parameter reference value, then fresh air is can be completed by mobile phone in user
The clean-up performance for monitoring filter screen at any time is accomplished in the detection of air quality and the adjusting of strainer service condition, ensures room air
While quality, Creating A Humanity smart home life improves air-conditioner set operational effect.
