Description
Technical field
The present invention relates to household appliance technical fields, more specifically, are related to a kind of air cleaning unit and a kind of air purification
Method.
Background technology
Used by air cleaning unit currently on the market dust removal method it is general there are three types of, the first be HEPA filtering
Net dedusting, second is cyclone dust removal, the third is electrostatic precipitation.HEPA filter screen dedusting technologies are sticked by HEPA filter screens
Fine particle in attached air, so as to which fine particle be made to be detached with gas, if to reach good clean-up effect, then will
Increase the windage of HEPA filter screens, but can cause the noise of air cleaning unit very big in this way.Cyclone dust removal is to make air along gas
The madial wall convolution for revolving case rises, so that the fine particle in air declines harmonic motion speed in centrifugal force, gravity, so as to
Fine particle is made to be detached with gas, if to reach good clean-up effect, then air will be increased and circled round in cyclone case
The stroke walked, but the air output of air cleaning unit can be caused too low in this way.Electrostatic precipitation is the electric discharge by ionization device
Electrode makes the fine particle in air with charge, and the connection electrode for passing through ionization device makes air cleaning unit carry and institute
The opposite polarity charge of fine particle is stated, so that the fine particle in air is acted in Coulomb force declines harmonic motion speed, so as to
Fine particle is made to be detached with gas, if to reach good clean-up effect, then the voltage of discharge electrode, but this will be increased
Sample can generate a large amount of ozone, influence the health of user.
Therefore, it how while product air purification effect is promoted, reduces the noise of product, promote the air output of product
And the production quantity for reducing ozone becomes current urgent problem to be solved.
Invention content

If amount is less than 100 cubes ms/h, unit of the product time inner air-cleaning amount is too low, and air output is also small.Air output is more than
If 600 cubes ms/h, intake is excessive, can cause the noise of product excessive in this way, and big intake needs to use big work(
The wind turbine of rate, the energy consumption for also resulting in product in this way are excessively high.The lift angle that air swirl rises is in the range of 5 ° to 45 °.Lift angle
If 5 °, air the walked stroke that circles round in cyclone case is long, so that the air output of product is too small.Lift angle is more than 45 °
If, air the walked stroke that circles round in cyclone case is too short, so that the air purification effect of product is undesirable.The thickness of adhesion layer
Degree can not only ensure that adhesion layer had good adhesion effect, but also can avoid providing in this way in the range of 200 microns to 1200 microns
Source wastes, to control the production cost of product.
According to one embodiment of present invention, the air purification method further includes：Cleaning module is net to the cyclone case
Gas after change is purified.
Air purification method according to an embodiment of the invention carries out cyclone case purified gas by cleaning module
Double purification can further promote the clean-up effect of the air purification method.Wherein, cleaning module can be selected gaseous pollutant and urge
Change cleaning module, ozone removal module etc., gaseous pollutant catalytic purification module can remove the organic pollution in gas, be promoted
The air purification method can purifying contaminated object diversity, ozone removal module can remove ozone in air, ozone avoided to endanger
The health of evil user.Specifically, ozone removal net or ozone reduction net can be selected in ozone removal module.

The water-washing method of active adhesion substances, after by this cleaning way, the fine particle on 2 surface of adhesion layer is washed away, adhesion layer 2
It can be continuing with.
As shown in Fig. 2, the embodiment of second aspect of the present invention provides a kind of embodiment for first aspect present invention
The air purification method of the air cleaning unit of offer, including：Ionization device makes the side of the fine particle and cyclone case in air V
Wall 1 is with opposite charge；Air-supply arrangement is entered the air V in the cyclone case by the air inlet 11 of the cyclone case；
The madial wall convolution of the air V along the cyclone case, which rises, to be made, and adhesion layer sticks the fine particle in air, so that the sky
Fine particle in gas V is detached with gas；Pure air after being detached with fine particle is discharged from gas outlet 12.
Air purification method according to an embodiment of the invention contains fine particle in air V, and ionization device makes air V
In fine particle with the charge opposite with side wall 1, air V is entered gas by air-supply arrangement with certain initial velocity from air inlet 11
After revolving case inside, the madial wall of air V along cyclone case, which circles round, to be risen, so that the fine particle in air V is in centrifugal force F, gravity G
Effect declines harmonic motion speed, and when air V rises along the madial wall convolution of cyclone case, the electrification fine particle in air V can also
By Coulomb force FQEffect, Coulomb force FQSide wall 1 is made to attract each other with electrification fine particle, to reduce the movement velocity of fine particle,
Meanwhile the adhesion layer 2 in cyclone box inner wall can also cause the fine particle in air V viscous force F η, make fine particle
Movement velocity reduces, and sticks fine particle, so as to which fine particle be made to be detached with gas, after then being detached with fine particle
Pure air is discharged from gas outlet.The air purification method, which has coupled, sticks three kinds of dedusting, cyclone dust removal and electrostatic precipitation dedustings
Mode greatly improves air purification effect.By above-mentioned air purification method, while air purification effect is promoted, both
Air can be shortened to circle round in cyclone case walked stroke, still there is higher speed when ensureing that gas reaches gas outlet 12,
So as to improve the air output of product, and the voltage of discharge electrode can be reduced, to reduce the production quantity of ozone.And adhesion layer 2 is set
Put on the madial wall of cyclone case the windage very little so that adhesion layer 2, in this way can while product air purification effect is promoted,
Substantially reduce the noise of product.
Preferably, the air output of air-supply arrangement is in the range of 100 cubes ms/h to 600 cubes ms/h.Air-supply
If amount is less than 100 cubes ms/h, unit of the product time inner air-cleaning amount is too low, and air output is also small.Air output is more than
If 600 cubes ms/h, intake is excessive, can cause the noise of product excessive in this way, and big intake needs to use big work(
The wind turbine of rate, the energy consumption for also resulting in product in this way are excessively high.The lift angle that air swirl rises is in the range of 5 ° to 45 °.Lift angle
If 5 °, air the walked stroke that circles round in cyclone case is long, so that the air output of product is too small.Lift angle is more than 45 °
If, air the walked stroke that circles round in cyclone case is too short, so that the air purification effect of product is undesirable.Adhesion layer 2
Thickness can not only ensure that adhesion layer 2 had good adhesion effect, but also can keep away in this way in the range of 200 microns to 1200 microns
Exempt from the wasting of resources, to control the production cost of product.
According to one embodiment of present invention, the air purification method further includes：By cleaning module to the cyclone
Case purified gas is purified.
Air purification method according to an embodiment of the invention carries out cyclone case purified gas by cleaning module
Double purification can further promote the clean-up effect of the air purification method.Wherein, cleaning module can be selected gaseous pollutant and urge
Change cleaning module, ozone removal module etc., gaseous pollutant catalytic purification module can remove the organic pollution in gas, be promoted
The air purification method can purifying contaminated object diversity, ozone removal module can remove ozone in air, ozone avoided to endanger
The health of evil user.Specifically, ozone removal net or ozone reduction net can be selected in ozone removal module.
