When power supply provides voltage to make having high voltage differential between the suction layer B of each blade 4 and shell of compression A to the shell of compression A of each blade 4 and suction layer B, when motor 24 drives centrifugal wind wheel 1 to rotate simultaneously, air enters in spiral case 23 from air inlet 26, now the dust granules of air enters in the dedusting passage that adjacent blade 4 limits, this dedusting passage is the high voltage place of charging, when dust granules is by dedusting passage, the dust granules (band plus or minus electric charge) of charging and the dust granules of any neutrality all bear highfield, highfield makes dust granules adsorb and is collected in the surface of blade 4, achieve the object of the air entered in spiral case 23 being carried out to dedusting, air after dedusting is discharged from air outlet 28.
According to the air processor 100 of the embodiment of the present invention, by being provided with above-mentioned centrifugal wind wheel 1, thus not only can realize the object of dedusting, and the shortcoming such as the power consumption overcoming the air-purification filter device in correlation technique is large, resistance is high, noise is high, have simple and reasonable, dust collection efficiency is high, resistance is little, power consumption is low, noise is little, do not have the feature of the pressure loss.
Wherein, it should be noted that, according to the needs of use occasion, the dust removing effects according to the air processor 100 of the embodiment of the present invention can also by regulating the potential difference of two potential ends of power supply, regulating the rotating speed of centrifugal wind wheel 1 and realize regulating by different blade quantities, different blade heights and different blade shapes.And when blade 4 surface of centrifugal wind wheel 1 has been filled dust, centrifugal wind wheel 1 can be removed cleaning, such as scrub with hairbrush or soak with abluent, dry or can continue after drying up to use.The dust on blade 4 surface can also be removed to get off to collect in dust collecting sleeve by design automatic dust-removing structure.
In further embodiment of the present invention, as shown in figure 13, air processor 100 also comprises high voltage source 9, and high voltage source 9 is connected to provide voltage with shell of compression A with the suction layer B of each blade 4 respectively, makes to have voltage difference between the suction layer B of each blade 4 and shell of compression A.Thus make air processor 100 without the need to being connected with extraneous power supply, be convenient to the use of air processor 100.Particularly, the first conducting ring 7 is connected with the cold end in high voltage source 9 or hot end by wire, Carbon fibe silk, conductive contact or slide block.Second conducting ring 8 is connected with the cold end in high voltage source 9 or hot end by wire, Carbon fibe silk, conductive contact or slide block.
In the example of fig. 1, the second conducting ring 8 be communicated with shell of compression A is connected with the hot end wire 17 of high voltage source 9 by a contact terminal 15, the hot end wire 17 of high voltage source 9 is made up of high internal resistance material, even if damaged with the insulating sheath ensureing hot end wire 17, hot end wire 17 is by also can not be dangerous after human contact.The first conducting ring 7 be communicated with suction layer B is connected with the cold end wire 16 of high voltage source 9 by another contact terminal 15.
As shown in Figure 12 and Figure 13, in further embodiment of the present invention, air processor 100 also comprises the anion emission ionization device 18 for making the dust granules in air charge.Thus by charging to the dust granules in air, dust granules charged is like this caught by high voltage electric field absorption rapidly in the dedusting passage entering centrifugal wind wheel 1, and then further increases dust removing effects.
Particularly, as shown in figure 12, anion emission ionization device 18 comprises: the main transmitter 19 of anion and the secondary transmitter 20 of cation, one end of the main transmitter 19 of anion is connected with the hot end of high voltage source 9.One end of the secondary transmitter 20 of cation is connected with the cold end of high voltage source 9, and the radius of curvature of the free end of the main transmitter 19 of anion is less than the radius of curvature of the free end of the secondary transmitter 20 of cation.That is, the main transmitter of anion 19 is connected to high negative potential, secondary transmitter 20 ground connection of cation, namely the earth terminal with high voltage source 9 is connected, free end like this due to the main transmitter of anion 19 is sharper, launch a large amount of anion stream, the secondary transmitter 20 of cation due to tip more blunt, launch a small amount of cation; Even if anion stream is neutralized by a small amount of cation that the secondary transmitter 20 of cation is launched, still residue has a large amount of anion stream for dust granules charging, makes dust granules electronegative.Like this, electronegative dust granules is caught by high voltage electric field absorption rapidly in the dedusting passage entering centrifugal wind wheel 1.Thus further improve dust removing effects.Preferably, the main transmitter 19 of anion is for having the metal object of sharp tip, and the radius of curvature at its tip is less than 0.1 millimeter.The secondary transmitter 20 of cation is for having the metal ball body of relatively blunt round end, and the radius of curvature at its tip is generally greater than 1 millimeter.
In the concrete example of Figure 12, high voltage source 9 is electrically connected by the main transmitter 19 of hot end wire 17 and anion, and high voltage source 9 is electrically connected by the secondary transmitter 20 of cold end wire 16 and cation.
Wherein, air inlet 26 place can be located at according to the anion emission ionization device 18 of the embodiment of the present invention, also can be located at air outlet 28 place, as long as can charge to the dust granules in air.
As shown in figure 13, in some embodiments of the invention, air processor 100 also comprises screen pack 21, and screen pack 21 is located at air inlet 26 place.This screen pack 21 can remove the dust larger with blocking diameter, such as hair, soft flocks, ball top, fiber or chip etc.Thus air enters in spiral case 23 after the filtration through screen pack 21 again, improves efficiency of dust collection further.Can adopt the similar airstrainer as screen window used in conventional air-conditioning device according to the screen pack 21 of the embodiment of the present invention, resistance is very little, and pressure drop only has 2-3 handkerchief.In the example in figure 13, anion emission ionization device 18 is arranged between screen pack 21 and air-ducting ring 22.
According to the dust removing effects of the air processor 100 of the embodiment of the present invention up to more than 99%, because the air-flow of all dedusting passages through blade 4 all can be cleaned, the space of 60 cubic metres can be purified within half an hour.Lift the dust removing effects that two concrete examples describe the air processor 100 according to the embodiment of the present invention below.
