Fig. 4 is the circuit diagram of the driving circuit representing ion generating device 18.The driving circuit of ion generating device 18 has terminal 80a, 80b of being connected with power circuit (not shown).Terminal 80a is transfused to+13V, and terminal 80b is maintained earthing potential and is connected to grounding jumper 90a.Connect cond C1 via resistance R1 between terminal 80a, 80b, be connected in parallel armature winding T1a and the transistor Q1 of step-up transformer T1 with cond C1.
Between terminal 80a and resistance R1, connect one end of impulse deviser 70, the other end of impulse deviser 70 is connected with the base stage of transistor Q1.The pulse wave of square wave is applied by impulse deviser 70 couples of transistor Q1.
One end of the secondary winding T1b of step-up transformer T1 is connected in parallel the 1st sparking electrode 181a and the 2nd sparking electrode 181b via diode D1, D2 that direction is contrary.The other end of secondary winding T1b is connected with the 1st induction electrode 182a and the 2nd induction electrode 182b and is connected with grounding jumper 90a via interrupteur SW 1.
The signal that interrupteur SW 1 exports according to the testing result according to corpuscle sensor 21 is opened, is closed, and switches the 1st release mode and the 2nd release mode.
When via power circuit to when applying the voltage of DC13V between terminal 80a, 80b, cond C1 is charged via R1.When impulse deviser 70 in this condition generates the pulse wave of square wave and applies pulse wave to transistor Q1, the electric charge charged by cond C1 discharges to earthing potential through the armature winding T1a of step-up transformer T1.
Now, in secondary winding T1b, produce the high potential of the pulse type after boosting.Thus, high potential (such as 2kV) is applied via diode D1, D2 to the 1st, the 2nd sparking electrode 181a, 181b from the secondary winding T1b of step-up transformer T1.
Under the 1st release mode, interrupteur SW 1 is turned off, and the 1st, the 2nd induction electrode 182a, 182b and grounding jumper 90a is not connected.

In addition, when performing the 2nd release mode when making interrupteur SW 1 connect, the 1st, the 2nd induction electrode 182a, 182b and grounding jumper 90a is connected.That is, the 1st, the 2nd induction electrode 182a, 182b is via interrupteur SW 1 ground connection.
Thus, the positive ion produced between the 2nd sparking electrode 181b and the 2nd induction electrode 182b is attracted by the 1st sparking electrode 181a and almost disappears from air flue 13.
Fig. 5 is the diagram of circuit of the action of the vehicle air clean-up device 2 representing above-mentioned formation.In addition, in cooling operation, heating running and air-supply running, similarly perform the 1st release mode and the 2nd release mode, be therefore described for the situation of cooling operation at this.When selecting cooling operation by the operation of operating switch after the engine starting making vehicle 1, closing extraneous gas sucking hole 11a by switch regulator 31 and opening internal gas sucking hole 11b.
Supply ventilating fan 15 is driven in step #1.Thus, the internal gas circulation being also again taken into air flue 13 in compartment 6 is transported to after carrying out that the air in compartment 6 is taken into air flue 13 from internal gas sucking hole 11b from blow-off outlet 12.Now, compressor makes refrigerant at circulation stream Inner eycle, and refrigerant flows into evaporator 16.Have passed through the air of evaporator 16 cooled after from blow-off outlet 12 to transporting cold-air in compartment 6.Thus, cooling operation is carried out.In addition, the dust that the air of circulation comprises in air flue 13 or pollen etc. are caught collection by filter 14.
Detected the concentration of the PM2.5 in compartment 6 by corpuscle sensor 21 in step #2.In step #3, judge whether the concentration of the PM2.5 in compartment 6 becomes set upper limit concentration C i (such as 35 μ g/m
3) more than.The concentration of the PM2.5 in compartment 6 transfers to step #4 less than when upper concentration Ci, transfers to step #5 when more than upper concentration Ci.
In step #4, perform the 1st release mode, by ion generating device 18, negative ion and positive ion are discharged into air flue 13.Thereby, it is possible to degerming, the viral disactivation carried out in compartment 6 and stink are removed.
In step #5, perform the 2nd release mode, mainly negative ion is discharged into air flue 13 by ion generating device 18.Thus, main anion releasing in compartment 6, the PM2.5 in compartment 6 is electronegative.Further, electronegative PM2.5 is taken in air flue 13 via internal gas sucking hole 11b, by filter 14 control of dust of positively charged.Thus, reliably control of dust can be carried out to the PM2.5 in compartment 6.
Further, after step #4 and step #5, return step #2, repeat step #2 ~ step #5.
In addition, when making extraneous gas sucking hole 11a open when carrying out heating running or air-supply running, closing extraneous gas sucking hole 11a when the 2nd release mode of step #5 by switch regulator 31 and opening internal gas sucking hole 11b.Thus, carry out internal gas circulation time when heating running or air-supply running also at the 2nd release mode, control of dust can be carried out with the PM2.5 in filter 14 pairs of compartments 6.
In addition, make in the electronegative situation of filter 14, as long as at the upstream of the 2nd sparking electrode 181b configuration the 1st sparking electrode 181a.Thus, mainly in compartment 6, discharge positive ion when the 2nd release mode, the PM2.5 positively charged in compartment 6.Further, the PM2.5 of positively charged is taken into air flue 13, by electronegative filter dirt collection from internal gas sucking hole 11b.
According to the present embodiment, be there is the 1st release mode by ion generating device 18, negative ion and positive ion being discharged into air flue 13, therefore carried out the degerming and deodorizing in compartment 6 by negative ion and positive ion.
In addition, have and be discharged into the 2nd release mode of air flue 13 by ion generating device 18 by with the filter 14 of the positively charged negative ion that is contrary polarity, when the concentration of the PM2.5 (corpuscle) under the 1st release mode in compartment 6 exceedes set upper limit concentration C i, switch to the 2nd release mode.
Thus, when the 2nd release mode, by being contrary polarity with filter 14, negative ion makes the PM2.5 in compartment 6 charged, therefore, it is possible to the ground such as the HEPA filter not using particle dust collection efficiency high reliably carry out control of dust to the PM2.5 in compartment 6.Thus, the blocking of the reduction of air quantity or filter 14 can be prevented and control of dust not carried out to PM2.5 with reducing convenience.In addition, without the need to arranging with ion generating device 18 Charging system making the PM2.5 in compartment 6 charged independently, therefore, it is possible to suppress the cost of vehicle air clean-up device 2 to increase.
In addition, produce negative ion from the 1st sparking electrode 181a, produce positive ion from the 2nd sparking electrode 181b, the 1st sparking electrode 181a is configured at the downstream of the 2nd sparking electrode 181b, the shutdown switch SW1 when the 1st release mode, the turn on-switch SW1 when the 2nd release mode.
Thus, the positive ion discharged from the 2nd sparking electrode 181b when the 2nd release mode is attracted by the 1st sparking electrode 181a, and positive charge flows to earthing potential via grounding jumper 90a.Thus, the positive ion discharged from the 2nd sparking electrode 181b almost disappears from air flue 13.Consequently, roughly only negative ion can be transported in compartment 6 by simple formation.
