With the air pollution is getting more and more serious, one goes to get off work in autumn and winter when it is in a "cloudless." People are also aware of the harmful effects of air pollution on human health, and air purifiers have also been on the market in recent years A lot of people sought after Since the air purifier is a small electrical appliances, certainly in the course of such problems will arise. Encounter problems how to solve it?
There are people with wood, like Xiaobian, is a black hole in electrical appliances, each time using electrical appliances, electrical failure to see, do not know where to start? Maybe your first reaction is to find after-sales. Electricity caused serious damage to it? When calling, ask you what kind of failure, you are also face force? May wish to understand the air purifier several major common faults and solutions, do it yourself.
First, the introduction of air purifier
Simple to say is the air cleaner, air purifier, to adsorption decomposition, the transformation of various air pollutants, such as dust, pollen, odor, formaldehyde and other decoration pollution, bacteria, etc., effectively clean the air impurities and improve air quality.
Second, the principle of air purifier
Only a better understanding of the structure of the air purifier in order to better solve the problem.Air purifier usually consists of high voltage circuits, negative ion generators, fans, air filters and other systems.
When the purifier is running, the ventilator circulates the air in the space to circulate.The polluted air is filtered by the air filter to remove or adsorb various pollutants and then generate high-pressure DC by the negative ion generator installed in the air outlet to blow air Continuous ionization, resulting in a large number of negative ions, was sent to the outlet, the formation of negative ion wind, and in the air with positive dust, to clean, clean air role.
Third, the air purifier common four major faults
Fault 1: High-pressure indicator is not bright, the fan does not turn
Generally, there is a fault in the power fuse or the high-voltage generating circuit, and if you want to disassemble the electric tester and know the specific problem, you can check it according to the following steps.
1, check the fuse is blown, if broken, should find out the reasons and then replace.
2, check the step-up transformer coil is burned out, you can use a multimeter to measure the resistance, if the coil is open or short circuit, should be replaced with the same type transformer.
3, Check the voltage doubler rectifier circuit rectifier, capacitor is damaged, the oscillator is stopped vibration. Use a multimeter to detect the relevant components one by one, and then replace the burned components, you can troubleshoot.
Fault two: high pressure indicator light, but the fan does not turn
High pressure indicator light, indicating high-voltage power supply circuit are normal, the fan may be faulty.So solve: check whether the blade is stuck foreign body, the bearing is seriously worn, if no abnormalities, and then check the motor lead is open circuit and whether the winding Can be measured with a multimeter, if the winding open or open circuit, the fan motor should be replaced with the specifications.
If it is a negative ion air purifier, the following faults may also occur:
Fault three: ion generator spark between the poles
Check whether the ambient air humidity is too high, it may be the positive and negative pieces caused by bending deformation. Use tweezers to correct the pole piece, if it is still sparking, the air purifier can be moved to dry place to try the air, the general troubleshooting.
Fault four: anion concentration is low
There may be too much dust on the filter and the electrode, the deformation caused by the positive and negative electrodes may also be caused by the high pressure is too low.
First remove the dirt on the filter and the electrode, correct positive and negative films. If invalid, then check the circuit produced by high voltage. Check the step-up transformer, rectifier, capacitors and so on with a multimeter.
Fourth, air purifier maintenance
1, the front filter is generally the back cover of the chassis, will precipitate some dust, thus affecting the intake air, affecting the effect of air purification.Generally cleaned 1-2 times a month, you can use a vacuum cleaner to clean the dust, you can also use a rag , Brushes for cleaning, if the manufacturer can be washed, after cleaning to be dry after the air purifier into.
2, the filter: part of the filter is the need to regularly get the sun under the sun, so that the purification efficiency can be better maintained, such as activated carbon filters, six months to get the sun for 24 hours or more, you can restore the activated carbon itself Activity.
3, deodorant filter: a few brands of air purifier deodorant filter has reached the technical level was washable, can maintain the purification efficiency by washing to shorten the period for the filter can also be cleaned with a vacuum cleaner.
4, ion generator: generally built-in, do not need to clean, better ion generator work efficiency are higher.
