Below, illustrate according to electrostatic air purifier of the present invention with reference to Fig. 1-4.
As illustrated in fig. 1 and 2, this air cleaning unit has and for example applies-animating electrode (negative electrode) 1 of 6KV, for example first collecting electrode 2 of earthing potential and apply for example second collecting electrode 3 of 6KV.Animating electrode 1 forms cylindric, has a plurality of needle-like ledge 1a.The 1st collecting electrode 2 and the 2nd collecting electrode 3 are the strip metal plate, are wound on the surface of diameter less than the cylindric insulation support body 4 of the drum diameter of animating electrode 1 circularly.First collecting electrode 2 is configured in position near animating electrode 1, second collecting electrode 3 is configured in than the position of first collecting electrode 2 further from animating electrode 1.
Control of dust paper bobbin 6a is housed in the hollow space 5 of cylindric supporter 4, this control of dust paper bobbin 6a is rolled into tubular by the control of dust paper 6 as the control of dust thin plate with insulating properties and flexibility, in addition, be provided with and make control of dust paper bobbin 6a rotation freely the axle 7 of location and the wall of supporter 4 are provided with the groove 8 of control of dust paper 6 being pulled out usefulness from hollow space 5.Control of dust paper 6 is pulled out from groove 8, be wound in the mode that covers first collecting electrode 2 and the 2nd collecting electrode 3 on the whole outer peripheral face of cylindric supporter 4, be fixed on the cylindric supporter 4 with fixed part shown in Figure 19 then.Animating electrode 1 is fixed on the insulation support body 10 of seat stand shape.This seat stand shape supporter 10 is provided with the location step part 12 that forms the cover 11 of device as air duct as shown in the figure.And this seat stand shape supporter 10 is also supporting cylindric supporter 4, and then circuit arrangement 13 its inside of packing into.
As shown in Figure 1, be provided with loading and unloading lid 14 freely on the top of cylindric supporter 4, this middle body above lid 14 is being fixed motor 15, is connected with fan 16 on this motor 15.Motor 15 with synchronously drive animating electrode 1, collecting electrode 2 driving power and be connected with 3.That is, frequent hotwire 15.
The cover 11 that has as air duct organizator function is the cup-shaped of left-hand thread, and is made up of cylindric part 17 and top 18.Near animating electrode 1 place, as shown in Figure 3, the air intake 19 of a plurality of narrow slit shapes is set at cylindric part 17 downsides on the whole periphery of cylindric part 17.As shown in Figure 1, a plurality of air outlet slits 20 are set on top 18.Subtend in cover 11 cylindric part 17 is provided with opening in the zone of collecting electrode 2 and 3.Thereby, the air duct 21 shown in the space between the cylindric part 17 of cylindric supporter 4 and cover 11 becomes.
In addition, second collecting electrode 3 of this embodiment is made of a plurality of metallic plates (aluminium sheet) with aperture 22 of diameter 0.5/5mm, area 0.39～39.25mm square range.The effect of this aperture 22 will be reviewed explanation.
Operation principle
If to animating electrode 1 for example apply-6KV, to first collecting electrode 2 apply 0V and to second collecting electrode 3 for example apply+during 6KV, between the animating electrode 1 that plays cathodic process and first and second collecting electrodes 2,3, produce corona discharge, from electrode 1 towards first and two collecting electrodes 2,3 a large amount of electronics that flies out.By this corona discharge have with animating electrode 1 make airborne molecule (particularly oxygen molecule) negative electricity from.It is that negative electricity is from dust that the dust (for example: dust, bacterium, virus, tick dung, pollen etc.) that floats in the air becomes electronegative particle from anion reception electronics.Because it is the high potential of benchmark that first and second collecting electrodes 2,3 have with animating electrode 1, thereby be the positively charged state, be negative electricity from dust and the Coulomb force effect between the positive charge of collecting electrode 2,3 under, negative electricity moves towards collecting electrode 2,3 from dust, and the control of dust paper 6 that is wound onto on cylindric supporter 4 place's side faces holds.In addition, to produce the phenomenon move along specific direction be ion wind near the unipolarity ion DC electric field.Therefore, in the device of Fig. 1 and Fig. 2, produce from the ion wind of animating electrode 1 towards first and second collecting electrode 2,3.Also but, produce from the downside of cylindric supporter 4 ion wind towards upside.In addition, first collecting electrode 2 that is arranged between the animating electrode 1 and second collecting electrode 3 also has the Potential distribution of making effect uniformly and produces the ion wind action well.
The ion dust that moves along with ion wind is possible because of being adsorbed control of dust towards control of dust paper 6, but the good control of dust of quick-acting as illustrated and expeditiously control of dust be impossible.In the present embodiment, when driving animating electrode 1 and collecting electrode 2,3, CD-ROM drive motor 15 is rotated fan 16 at leisure.
Fan 16 forms and makes air be from bottom to top the form that moves, and therefore, when making fan 16 rotations, the downside of fan 16 becomes decompression state, and by the air intake 19 that covers 11 downsides, air is from covering 11 outer side inflow inboard; By air duct 21, air is discharged laterally from the air outlet 20 that covers 11 top 18.Forced air flow in the air duct 21 that is produced by fan 16, its speed is identical with ion wind speed or close.Because the ion wind wind speed of actual measurement is about 1m/see～5m/sec,,, be preferably in the scope of 2～3m/sec for example in the scope of 1～5m/sec so wish that the air velocity degree that is produced by fan Final 16 system is less than 5m/sec.Rotary fan 16 just can obtain such air stream at leisure.If rotary fan 16 at leisure, then the noise level by fan 16 just becomes extremely low.In case utilize the rotation of fan 16 to make air flows, be that the air flows at center promptly circulates and just produces with the air cleaning unit in the room so, foul atmosphere in the room just flows into the air intake 19 of cover 11, after being cleaned during by air duct 21, is discharged in the room from air outlet slit 20.Utilize fan 16 in a single day to produce air flows, the foul atmosphere in the room then as described above just is imported into air cleaning unit, thereby can improve purification speed.In addition, also can dust such on the ground that drop in the room be incorporated in the air cleaning unit, thereby improve dust catching efficiency.And, because the forced air flow that is produced by fan is near ion wind, thereby have booster action to locating a little less than the ion wind, make corresponding to can well attached equably dust on the large tracts of land of the large-area control of dust paper 6 of collecting electrode 3, and can improve dust catching efficiency.Have again,, therefore, be attached to dust on the control of dust paper 6 and can produce the phenomenon of peeling off because of wind hardly and can take place hardly because that the air flows that is produced by fan 16 does not have is such fast.If even the dust that has been ionized is on the control of dust paper more than 30% along with the air stream that is produced by fan 16 is transported to humidity, then also can be attached on the control of dust paper 6.And if owing to adhere to dust on the inoperative zone of electric field of the collecting electrode 3 of control of dust paper 6, then the humidity because of control of dust paper 6 still can keep dust.
Below, the effect of the aperture 22 of collecting electrode 3 is described.Cylindric supporter 4 with collecting electrode 2 and 3 is reeled such as resemble when having the control of dust paper 6 of flexibility the paper handkerchief, then as shown in Figure 4, the part of control of dust paper 6 produces the state that enters in the aperture 22, except that control of dust paper 6 have intrinsic concavo-convex, control of dust paper 6 produces the convex-concave surface corresponding to aperture 22.But since the Coulomb force to the ionization of the distance of leaving first and second collecting electrodes, 2,3 about 1mm the dust useful effect, therefore under the situation of thickness less than 1mm of control of dust paper 6, much less to the zone of the control of dust paper 6 that contacts with first and second collecting electrodes 2,3, exactly to the ionization on the control of dust paper zone that is positioned at aperture 22 dust, acted on by the Coulomb force.Therefore, control of dust paper 6 also can control of dust because of the Coulomb force in the part of aperture 22.In addition, humidity is under the situation more than 30%, and the zone of the control of dust paper 6 that contacts with collecting electrode 2,3 does not have the function as the adsorption plane of the dust that moves because of ion wind or fan 16.Therefore, when aperture 22 is big, near the zone of control of dust paper 6 aperture 22 peripheries have the dust that moves because of ion wind or fan 16 as the adsorption plane that produces because of the Coulomb force and conduct adsorption plane two aspect function.Has function as the adsorption plane of the dust that moves because of ion wind or fan 16 in the central area.From the above, because aperture 22 has produced the effect that increases control of dust paper 6 surface areas.And, be adsorbed on dust on the zone in hole 22 of control of dust paper 6 and become to be difficult to produce and peel off, and can improve dust catching efficiency.
