Embodiment
Neutralization takes place for the cation that suppresses to take place and anion and eliminates and the dipolar ion that will take place effectively is released in the space in ion generating device of the present invention near the electrode of ion generating device; Not to adopt the mode that cation and anion alternately take place with specified period with single ion generating device; The structure that cation and anion also are released to indoor mode (below, be called ion and independently emit mode) independently of one another individually takes place but adopt with a plurality of ion generating devices.
Before the above-mentioned ion of employing is independently emitted mode, carry out following infrastest earlier.Have again; Mode as the ion generating device that in this experiment, uses; Though can adopt the structure of needle electrode, here, consider with being arranged on the structure that dielectric lip-deep sparking electrode induction electrode inner with being embedded in dielectric constitutes pair of electrodes.
Figure 1A～Fig. 1 H is the sketch map that expression ion of the present invention is independently emitted the infrastest example of mode.Figure 1A is the outside drawing of ion generating device, and Figure 1B is the profile of ion generating device, and Fig. 1 C is that the voltage between sparking electrode and the induction electrode applies waveform, and Fig. 1 D～Fig. 1 G is measuring condition figure, and Fig. 1 H is the configuration example of ion generating device.
At first; In current experiment; Use the ion generating device 1 shown in Figure 1A, Figure 1B; Be utilized in apply ac pulse voltage (Fig. 1 C) between its sparking electrode 0a and the induction electrode 0b thus with specified period alternately take place cation and anion situation (Fig. 1 D) thereby and use identical ion generating device 1 to apply ac pulse voltage to be biased to the only situation of generating negative ions (not diagram) of negative waveform, to measure the ion discharging amount respectively, what kind of difference checking has on separately.Consequently, be about the latter's 50～60 [%] of anion detection limit at the former the total detection limit of cation and anion.
Then, be conceived to The above results, with 2 ion generating device 1a same as described above, 1b side by side, measure respectively cation, the total ion discharging amount of the situation of generating negative ions (Fig. 1 E～Fig. 1 G) only individually only take place.
Consequently; The total detection limit of cation that under the condition determination of Fig. 1 E, obtains and anion becomes the value that the cation detection limit that obtains with the situation of using above-mentioned 2 ion generating devices individually to measure the ion discharging amount and the aggregate value of anion detection limit equate substantially.Hence one can see that, be not with specified period the mode of cation and anion to take place alternately with single ion generating device, but the ion generating device that adopts ion independently to emit mode is effective.
But; In Fig. 1 E; With being configured in side by side on the direction with from the air-supply quadrature of fan 2 of the 1st discharge part (ion generating device 1a) and the 2nd discharge part (ion generating device 1b), through the stream of the air on the ion generating device through on another ion generating device.
On the other hand; Shown in Fig. 1 F, Fig. 1 G; From Fig. 1 E laying method is changed 90 degree, when make ion generating device 1a and ion generating device 1b be configured in side by side with the direction parallel from the air-supply of fan 2 on the time, confirm to decay at the ionic weight of the discharge part generation that is positioned at windward.When describing particularly, in Fig. 1 F, because the cation that the ion generating device 1a that is in the wind takes place is through on the ion generating device 1b of leeward, so this cation is neutralized the amount decay of cation by the negative potential of ion generating device 1b.Likewise, in Fig. 1 G, the decay of the anion of the ion generating device 1b of windward.Hence one can see that, even adopt ion independently to emit mode, and because of the configuration ion of discharge part can not be emitted effectively, the decay of the ion of folk prescription, the balance of emitting of cation and anion is collapsed.
Here, the measurement of ion is to utilize the double cylinder-shaped ion counter of Ge Dien (Gerdien) 3 to carry out results measured, obtains the concentration [individual/cc] at measurement point as measured value.Owing to measured the size of the ion concentration that obtains at the same terms, identical measurement point, so in article, how much show the height of concentration with ionic weight.
Ion generating device is being carried under the situation at device interior; Even in order to become by the equipment air-supply the sparking electrode surface on the dielectric from any one the direction air-supply of X-direction Y direction; The ion that the discharge part that also can prevent to be in the wind takes place is neutralized on the discharge part of the opposite polarity of leeward, and direction X axle or Y direction with respect to air-supply preferably are configured in ion generating device 1a, 1b on the diagonal; Be tilted configuration, to reduce wherein and (with reference to Fig. 1 H).But owing to aspect area, be disadvantageous, under the situation of air supply direction decision, opposite hope is not configured on the diagonal.
In addition, carry out infrastest, the relation of distance and the dosis neutralisata of two ions of generation between the sparking electrode of the sparking electrode of this experimental study generation cation and the sparking electrode of generating negative ions.Fig. 6 A～Fig. 6 D is the sketch map that expression ion of the present invention is independently emitted other infrastests of mode.Fig. 6 A is the electrode allocation plan of the face side of membrane electrode, and Fig. 6 B is the electrode allocation plan of the rear side of membrane electrode, and Fig. 6 C is that the voltage between sparking electrode and the induction electrode applies waveform, and Fig. 6 D is condition determination figure.
In Fig. 6 A～Fig. 6 D, the 60th, thereby through in print copper on the polyimide film and carry out the etching membrane electrode of 2 electrodes of each self-forming on the face of the face of face side, rear side respectively.Shown in Fig. 6 A; On the face of face side; Between the sparking electrode of space, will be similar to sparking electrode 61a, the 62a that partly makes lattice-shaped in the rectangle apart from forming on the position of d; Shown in Fig. 6 B, overleaf on the face of side, with sparking electrode 61a, 62a opposed position on form induction electrode 61b, the 62b of the approximate solid shape of rectangle.Have, in order to prevent that paradoxical discharge takes place in the end of sparking electrode 61a, 62a, induction electrode 61b, 62b form in the inboard littler than sparking electrode 61a, 62a again.
In addition, be solder pad 63 with being arranged on the part that the black circle on each electrode representes, via being welded in the lead-in wire here etc., on each electrode, applying high voltage and make it discharge ion takes place.The ac pulse voltage of oscillation exchange decay waveform that will be shown in Fig. 6 C is biased to just after-applied between sparking electrode 61a, induction electrode 61b, identical ac pulse voltage is biased to negative after-applied between sparking electrode 62a, induction electrode 62b.Thus, from sparking electrode 61a cation takes place, from sparking electrode 62a generating negative ions.Have, the wave height value Vop of the 1st ripple of the ac pulse voltage that applies is about 3kV again.
And; Make a plurality of membrane electrodes 60 that changed apart from d that make between sparking electrode; Shown in Fig. 6 D; To each membrane electrode 60, membrane electrode 60 is placed between fan 2 and the ion counter 3, thereby apply above-mentioned ac pulse voltage is biased to the positive and negative two ions ion concentration separately that just reaches negative waveform mensuration generation.Measurement is to the situation that cation only takes place, only the situation of generating negative ions and 3 types of situation of situation that positive and negative two ions take place are simultaneously carried out.Having, at this moment, is 25cm between ion generating device 60 and the ion counter 3 again, and the both is configured on the top position of test desk 4.5cm.
And Fig. 7 is its mensuration of expression result's figure.Have, the temperature during mensuration is that 27 ℃, humidity are 27% again.From this measurement result, can know, if between sparking electrode apart from d more than or equal to 5mm, flashing (sparkover) not between sparking electrode 61a, 62a then.In addition, making between sparking electrode apart from d is 8mm, and then cation, anion all are that ion number when a side the is taken place ion number when taking place simultaneously with two sides equates.Hence one can see that, under the condition of the membrane electrode that in this is measured, uses, if make between sparking electrode apart from d more than or equal to 8mm the neutralization of positive and negative two ions that then can prevent.Though help preventing spark more greatly more apart from d between sparking electrode; Help preventing the neutralization of two ions; But because when distance increased, the size of ion generating device also increased, thus consideration so long as above-mentioned condition just get final product being set at about 8mm apart from d between sparking electrode.Have again; When making makes between sparking electrode the sample apart from the variable in distance of d; The membrane electrode that in this mensuration, uses is guaranteed between sparking electrode the distance apart from d through etching; Only on this part, remove the coat on coated electrode surface, be in the state that a part that makes sparking electrode end face opposite each other is exposed copper.Therefore, in the electrode of the reality of following record,, can infer and to make between sparking electrode value littler apart from d through the existence of coat.

In addition, the electrode shape shown in Fig. 2 A, Fig. 3, Fig. 4 A, Fig. 4 B is an example, also can be the such electrode shape of Fig. 8～Figure 11.Fig. 8～Figure 11 is the general view of the 5th～the 8th execution mode of expression ion generating device of the present invention.In Fig. 8～Figure 11, on the part identical, mark prosign with Fig. 3, omit its explanation.In addition, the structure of profile also can think identical with Fig. 2 B.
Ion generating device 10 shown in Figure 8 is to do the size of each electrode little; So that the end face of the 1st sparking electrode 12a, the 2nd sparking electrode 13a is within reason approaching, ion generating device 10 shown in Figure 9 is in order to adjust discharge position the 1st sparking electrode 12a of ion generating device shown in Figure 8 10, the number of the 2nd sparking electrode 13a to be reduced the device that forms.In addition, Figure 10, ion generating device 10 shown in Figure 11 are in order to adjust discharge position the 1st sparking electrode 12a of ion generating device shown in Figure 9 10, the shape of the 2nd sparking electrode 13a to be made and the 1st sparking electrode 12a of ion generating device shown in Figure 2 10, the approaching device of image of the 2nd sparking electrode 13a.
Then, account for voltage applies the structure and the work of circuit 20.
Fig. 5 A, Fig. 5 B are the circuit diagrams of an execution mode of expression voltage applying circuit 20.At first, the voltage applying circuit shown in the key diagram 5A 20.Voltage applying circuit 20 shown in Fig. 5 A has as the primary side drive circuit: input power supply 201, input resistance 204, rectifier diode 206, transformer drive with switch element 212, electric capacity 211, diode 207.At input power supply 201 is to exchange under the situation of source power supply; Voltage through input power supply 201 gives electric capacity 211 chargings via input resistance 204, rectifier diode 206; When becoming more than or equal to assigned voltage; Transformer drives with switch element 212 conductings, on the primary side coil 202a of transformer 202, applies voltage.Then, the primary side coil 202a of energy through transformer 202 that is charged on the electric capacity 211 drives with switch element 212 discharges with transformer, and the voltage of electric capacity 211 turns back to zero, charges once more, discharges and recharges repeatedly with the cycle of stipulating.Transformer drives with switch element 212 and in above-mentioned explanation, just adopts no grid 2 end thyristors (" Sidac " [product of new electric unit industry]) to be illustrated, but uses some different circuits, also can use thyristor (SCR).In addition, even be under the situation of DC power supply at input power supply 201, so long as can access the circuit with above-mentioned same work, just no matter be any circuit.That is, as the primary side drive circuit of this circuit, not special restriction gets final product so long as can access the circuit of same work.
Secondary-side circuitry as transformer 202; Be equipped with 2 secondary coil 202b, the 202c of transformer 202, these coils are connected with Fig. 2 A, Fig. 2 B, Fig. 3, Fig. 4 A, Fig. 4 B, any one the 1st sparking electrode 12a of Fig. 8～Figure 11, the 1st induction electrode 12b, the 2nd sparking electrode 13a, the 2nd induction electrode 13b respectively.Transformer through primary-side circuitry drives with switch element 212 conductings, and the NE BY ENERGY TRANSFER of primary side is to secondary coil 202b, the 202c of transformer, pulsing shape voltage.The secondary coil 202b that on the 1st sparking electrode 12a, not only connects transformer 202, but also the negative electrode of connection diode 209, the anode of diode 209 is connected via resistance 205 ground connection or with one-sided (reference potential) of input power supply 201.When input power supply 201 is when exchanging source power supply, because the folk prescription ground connection of input AC source power supply in Japan, so can access identical functions if the electric equipment etc. that does not have an earth terminal and input power supply 201 one-sided is connected.Even socket inserts on the contrary, only overlapping 100V is identical with ground connection.In addition, resistance 205 is to protect usefulness, does not also influence work even without this resistance (short circuit).In addition, on the 2nd sparking electrode 13a, not only connect the secondary coil 202c of transformer, but also connect the anode of diode 208, the negative electrode of diode 208 is connected via resistance 205 ground connection or with input the one-sided of power supply 201.
Then, the voltage applying circuit 20 of other structures shown in the key diagram 5B.The explanation of the primary-side circuitry of transformer 202 and above-mentioned same.Secondary-side circuitry as transformer 202; The secondary coil of transformer 202 is equipped with 2 202b, 202c, and these coils are connected with Fig. 2 A, Fig. 2 B, Fig. 3, Fig. 4 A, Fig. 4 B, any one the 1st sparking electrode 12a of Fig. 8～Figure 11, the 1st induction electrode 12b, the 2nd sparking electrode 13a, the 2nd induction electrode 13b respectively.On the 1st sparking electrode 12a; The secondary coil 202b that not only connects transformer 202; But also connect the negative electrode of diode 209 and the anode of diode 210; The anode of diode 209 is connected with 1 selection terminal 203a of transfer relay 203, and the negative electrode of diode 210 is connected with another selection terminal 203b of transfer relay 203 in addition.The public terminal 203c of transfer relay 203 is connected via resistance 205 ground connection or with input the one-sided of power supply 201.
Then, the operating voltage waveform is described.On the two ends of the secondary coil 202b of transformer 202,202c, apply the impulse waveform of the such alternating voltage of Fig. 5 C.The diode 209 that is connected with secondary coil 202b, 202c and the direction of diode 208 are reverse as stated; With the voltage of the 1st sparking electrode 12a, the 1st induction electrode 12b, the 2nd sparking electrode 13a, the 2nd induction electrode 13b with earth terminal, according to circumstances with the one-sided (reference potential: the waveform when a side that connects diode 208,209) be the benchmark observation of input power supply 201; Shown in Fig. 5 D, Fig. 5 E, Fig. 5 F, Fig. 5 G, the waveform of Fig. 5 C becomes and is biased to positive and negative waveform respectively.
Under the situation of Fig. 5 A illustrated embodiment; The 1st sparking electrode 12a, the 1st induction electrode 12b are with earth terminal, according to circumstances to import the one-sided (reference potential: be that the current potential that benchmark is observed just all is a side that connects diode 208,209) of power supply 201; The anion that takes place neutralizes on sparking electrode 12a, repels and emits cation.In addition, the 2nd sparking electrode 13a, the 2nd induction electrode 13b are with earth terminal, according to circumstances to import the one-sided (reference potential: be that the current potential that benchmark is observed all is negative a side that connects diode 208,209), emit anion of power supply 201.
In addition; Under the situation of Fig. 5 B illustrated embodiment; When transfer relay 203 is positioned at selection terminal 203a one side; The 1st sparking electrode 12a, the 1st induction electrode 12b are with earth terminal, according to circumstances to import the one-sided (reference potential: be that the current potential that benchmark is observed just all is a side that connects diode 208,209), cation takes place of power supply 201.In addition, be positioned at when selecting terminal 203b one side at transfer relay 203, with earth terminal, according to circumstances with input power supply 201 one-sided (reference potential: be that the current potential of benchmark observation all is negative a side that connects diode 208,209), generating negative ions.The 2nd sparking electrode 13a, the 2nd induction electrode 13b with earth terminal, according to circumstances with input power supply 201 one-sided (reference potential: be that the current potential of benchmark observation all is negative a side that connects diode 208,209), generating negative ions.
As cation is H +(H 2O) m, be O as anion 2 -(H 20) n(m, n are natural numbers, mean to have a plurality of H 2The O molecule).
Like this, when the selection terminal of transfer relay 203 was positioned at 203a one side, the ion that takes place from the 1st discharge part 12 became cation, with the anion that takes place from the 2nd discharge part 13, the ion of positive and negative roughly equivalent amount had taken place.Through in air, roughly emitting H with amount +(H 2O) mWith O 2 -(H 2O) n, these ions surround airborne mycoplankton or virus around, the effect of the hydroxy (OH) through the free radical that generates this moment can be deactivated.
Tell about above-mentioned record in detail.Through between the electrode that constitutes the 1st, the 2nd discharge part 12,13, applying alternating voltage, airborne oxygen and even moisture are accepted energy through ionization, produce ionization, generate with H +(H 2O) m(m be natural number) arbitrarily and O 2 -(H 2O) n(n be natural number) arbitrarily is the ion of main body these ions to be released in the space through fan etc.These H +(H 2O) mAnd O 2 -(H 2O) nOn the surface attached to the bacterium that swims, generate H behind the chemical reaction as free radical 2O 2Perhaps (OH).Because H 2O 2Perhaps (OH) shows extremely strong activity, thus, can surround airborne planktonic bacteria it is lost activity., (OH) be a kind of free radical here, expression atomic group OH.
Negative ions carries out chemical reaction at the cell surface of planktonic bacteria suc as formula that kind shown in (1)～formula (3), generates the hydrogen peroxide H as free radical 2O 2Perhaps hydroxy (OH).Here, in formula (1)～formula (3), m, m ', n, n ' are any natural numbers.Thus, destroy planktonic bacteria through the decomposition of free radical.Therefore, airborne planktonic bacteria is lost activity and be removed.
H +(H 2O) m+O 2 -(H 2O) n→·OH+1/2O 2+(m+n)H 2O…(1)
H +(H 2O) m+H +(H 2O) m′+O 2 -(H 2O) n+O 2 -(H 2O) n′→2·OH+O 2+(m+m’+n+n’)H 2O…(2)
H +(H 2O) m+H +(H 2O) m′+O 2 -(H 2O) n+O 2 -(H 2O) n′→H 2O 2+O 2+(m+m’+n+n’)H 2O…(3)
By above mechanism,, can access the effect of deactivating of the bacterium that swims etc. through emitting above-mentioned negative ions.
In addition, above-mentioned formula (1)～formula (3) is even because aerial harmful substance surface also can generate same effect, so as the hydrogen peroxide H of free radical 2O 2Perhaps hydroxy (OH) oxidation or decomposing harmful substances, through chemical substances such as formaldehyde and ammonia being converted to carbon dioxide and harmless material such as water, nitrogen, can be innoxious in fact.
Therefore, through driving Air Blast fan, can the cation and the anion that taken place by ion generating device 1 be passed out to outside the main body.And, through the effect of these cations and anion, airborne mould and bacterium are lost activity, can suppress its propagation.
In addition, in cation and anion, make the also deactivated effects of virus type such as Coxsackie virus, poliovirus, can prevent the pollution that causes of sneaking into because of these viruses.
In addition, confirm that also cation and anion have the effect of the molecule that is decomposed into the stink reason, can use the deodorizing in space.
In addition, when the selection terminal of transfer relay 203 was positioned at 203b one side, the ion that takes place from the 1st discharge part 12 became anion, together became from both sides' electrode generating negative ions all with the anion that takes place from the 2nd discharge part 13.Thereby perhaps try to achieve under the situation of loosening effect when supplying with anion hope and obtaining cation such in the natural forest in a large number in the too much space of cation becoming with the anion poised state because of the electric equipment in the family etc., very effective.
In addition; Because voltage applying circuit 20 can apply the alternating voltage waveform that begins from positive polarity between the 1st sparking electrode 12a shown in any one of Fig. 2 A, Fig. 2 B, Fig. 3, Fig. 4 A, Fig. 4 B, Fig. 8～Figure 11 and the 1st induction electrode 12b; Between the 2nd sparking electrode 13a and the 2nd induction electrode 13b, applying the alternating voltage waveform that begins from negative polarity gets final product; So, for example, can adopt Figure 12, structure shown in Figure 13 shown in Fig. 5 A, Fig. 5 B beyond the structure.
Figure 12 is than the circuit of Fig. 5 B structure that reduced of cheapness and component number more.For convenience of description; On the part identical with the execution mode shown in Fig. 5 B, mark prosign, voltage applying circuit 20 shown in Figure 12 has as the primary side drive circuit: input power supply 201, input impedance 204, rectifier diode 206, transformer drive with switch element 212, electric capacity 211, fly-wheel diode 213.At input power supply 201 is to exchange under the situation of source power supply; Through the input power supply 201 voltage via input resistance 204, rectifier diode 206; To electric capacity 211 chargings; If become more than or equal to assigned voltage, then transformer drives with switch element 212 conductings, on the primary side coil 202a of transformer 202, applies voltage.Then, the energy that is charged to electric capacity 211 drives with the primary side coil 202a discharge of switch element 212 with transformer 202 through transformer, and the voltage of electric capacity 211 turns back to zero, and charging discharges and recharges with specified period repeatedly once more.
Secondary-side circuitry as transformer 202; Be equipped with 2 secondary coil 202b, the 202c of transformer 202, these coils are connected with Fig. 2 A, Fig. 2 B, Fig. 3, Fig. 4 A, Fig. 4 B, any one the 1st sparking electrode 12a of Fig. 8～Figure 11, the 1st induction electrode 12b, the 2nd sparking electrode 13a, the 2nd induction electrode 13b respectively.Transformer through primary-side circuitry drives with switch element 212 conductings, and the NE BY ENERGY TRANSFER of primary side is to secondary coil 202b, the 202c of transformer, pulsing shape voltage.Have, each secondary coil and each electrode connect in the polarity of the polarity of the voltage that applies between the 1st sparking electrode 12a and the 1st induction electrode 12b and the voltage that between the 2nd sparking electrode 13a and the 2nd induction electrode 13b, applies opposite again.
In addition, on the 1st sparking electrode 12a, not only connect the secondary coil 202b of transformer 202, and connect the negative electrode of diode 209, the anode of diode 209 via relay 214 ground connection or with one-sided (the line AC2: reference potential) be connected of input power supply 201.When input power supply 201 is when exchanging source power supply because the folk prescription ground connection of input AC source power supply in Japan, so do not have earth terminal electric equipment etc. as long as with import power supply 201 one-sided just the connection can access identical functions.In addition, on the 2nd sparking electrode 13a, not only connect the secondary coil 202c of transformer 202, but also connect the anode of diode 208, the minus earth of diode 208 perhaps is connected with one-sided (the line AC2) of input power supply 201.
Then, the operating voltage waveform is described.On the two ends of the secondary coil 202b of transformer 202,202c, apply the impulse waveform of alternating voltage.Shown in Figure 14 A; At this moment; With the 1st sparking electrode 12a is that the voltage waveform of the 1st induction electrode 12b that observes of benchmark becomes the alternating voltage waveform that begins from positive polarity; Shown in Figure 14 B, be that the voltage waveform of the 2nd induction electrode 13b that observes of benchmark becomes the alternating voltage waveform that begins from negative polarity with the 2nd sparking electrode 13a.
In addition; Because secondary coil 202c is connected with line AC2 (according to circumstances being earth terminal) through the diode 208 of positive direction; With line AC2 is that the voltage waveform of the 2nd sparking electrode 13a that observes of benchmark is shown in Figure 15 A; In addition, the voltage waveform of the 2nd induction electrode 13b is shown in Figure 15 B, and the waveform of Figure 14 B becomes and is biased to negative waveform.Therefore, from the 2nd discharge part 13 generating negative ions.As anion is O 2 -(H 2O) n(n is a natural number, means to have a plurality of H 2The O molecule).
On the other hand; Because when relay 214 conductings; Secondary coil 202b is connected with line AC2 through reciprocal diode 209, and the voltage waveform of the 1st sparking electrode 12a that with line AC2 is the benchmark observation is shown in Figure 16 A, in addition; The voltage waveform of the 1st induction electrode 12b is shown in Figure 16 B, and the waveform of Figure 14 A becomes and is biased to positive waveform.Therefore, take place and the anion that takes place at the 2nd discharge part 13 cation of same quantity roughly from the 1st discharge part 12.As cation is H +(H 2O) m(m is a natural number, means to have a plurality of H 2The O molecule).
In addition, Figure 17 A changes the figure that time shaft comes the waveform shown in presentation graphs 14A or Figure 14 B, and Figure 17 B changes the figure that time shaft comes the waveform shown in presentation graphs 16A or Figure 16 B.The voltage waveform that is applied on each electrode becomes the impulse waveform that in the short like this time, decays, and this is because the electric oscillation decay that the electrostatic capacitance of the inductance of transformer and resistance, electrode causes and the effect of fly-wheel diode 213 cause.Promptly; Make the electric current that circulates through the voltage of on primary coil 202a, responding at secondary coil 202b, the last electric current that circulates of 202c, drive with switch element 212 backflows, thereby decay hastily at secondary coil 202b, the last voltage fluctuation that takes place of 202c through primary coil 202a, fly-wheel diode 213, transformer.
In addition, Figure 18 A is that expression is the oscillogram of voltage waveform of the 1st sparking electrode 12a, the 2nd sparking electrode 13a of benchmark observation with line AC2 when relay 214 conductings, and is identical with Figure 15 A, Figure 16 A.Figure 18 B is that expression is the oscillogram of voltage waveform of the 1st sparking electrode 12a, the 2nd sparking electrode 13a of benchmark observation with line AC2 when relay 214 breaks off.When relay 214 conductings, shown in Figure 18 A, the voltage waveform of the 1st sparking electrode 12a that representes with line L1 is biased to positive side, and the voltage waveform of the 2nd sparking electrode 13a that representes with line L2 is biased to minus side.And when relay 214 broke off, shown in Figure 18 B, the voltage waveform of the 2nd sparking electrode 13a that representes with line L2 was biased to not variation of minus side, and the voltage waveform of the 1st sparking electrode 12a that representes with line L1 is not changed to the alternation waveform with being biased.This is because when relay 214 disconnections, secondary coil 202b becomes floating state, the 1st ripple be bear, the 2nd ripple is the waveform of alternation later on, emits cation and anion two sides thus on a small quantity.
Therefore, when relay 214 broke off, a spot of cation and anion and a large amount of anion that takes place from the 2nd discharge part 13 that take place from the 1st discharge part 12 were as all states that becomes the anion affluence with cation and a large amount of anions of trace.On the other hand, when relay 214 conductings, utilize, become the state of the ion that positive and negative roughly isodose takes place from the 1st discharge part 12 cation that takes place and the anion that takes place from the 2nd discharge part 13.
Therefore, through conducting/disconnection relay 214, can switch following two kinds of situation: through in air, roughly emitting to equivalent amount H +(H 2O) mWith O 2 -(H 2O) n, these ions surround around airborne mycoplankton and the virus, the situation of the state that the effect of the hydroxy (OH) through the free radical that generates this moment is sought to deactivate; And becoming a large amount of anions of supplying with in the too much space of cation because of the electric equipment in the family etc., hope obtains in natural forest during the state of the ionic equilibrium of cation and anion or seek to loosen the situation of effect.
In addition, the such coil configuration of transformer 202 usefulness Figure 19 shown in Figure 12 constitutes.Figure 19 is the allocation plan of component configuration that the ion generating device of transformer shown in Figure 12 202 has been carried in expression.220 is electrode surface boards, the 221st of each electrode (not having diagram) of formation discharge usefulness in Figure 19, the electrode frame of fixed electrode panel part 220, the 222nd, moulding material, the 223rd, the substrate, the 224th of installation circuit block in stationary transformer 202, connector that input and output are used and the circuit-component carrying portion of carrying other circuit blocks.
Transformer 202 is the structures at the both sides of primary coil 202a configuration secondary coil 202b, 202c.When making the coil configuration of transformer 202 like this, can guarantee the distance between secondary coil 202b, the 202c, can alleviate in magnetic field that secondary coil takes place directly influence to another secondary coil.Therefore, alleviate the change of the voltage that on each secondary coil, takes place through mutual influence of magnetic field, can prevent to change from the ion generating capacity of the ion generating device that has been applied in the voltage that produces from each secondary coil.
Figure 13 is the circuit diagram of another other execution modes of expression voltage applying circuit 20.For convenience of description, on the part identical, mark prosign, omit its explanation with execution mode shown in Figure 12.Voltage applying circuit 20 shown in Figure 13 is with the difference of voltage applying circuit 20 shown in Figure 12: use 2 transformers 215,216 and be connected 2 fly-wheel diodes 217,218 on the primary coil separately, to replace 1 transformer 202 and fly-wheel diode 213 this point.In addition, the transformer as the primary side drive circuit drives with the place-exchange of switch element 212 with electric capacity 211.
At input power supply 201 is to exchange under the situation of source power supply; Through the input power supply 201 voltage via input resistance 204, rectifier diode 206, fly-wheel diode 217,218; Give electric capacity 211 chargings; When becoming more than or equal to assigned voltage, transformer drives with switch element 212 conductings, and voltage is applied on the series circuit of primary side coil 216a of primary side coil 215a and transformer 216 of transformer 215.Then; The energy of charging discharges through the series circuit that transformer drives the primary side coil 216a of primary side coil 215a with switch element 212, transformer 215, transformer 216 on electric capacity 211; The voltage of electric capacity 211 turns back to zero, and charging once more is with the specified period repeated charge.
Secondary coil 215b, 216b as the secondary circuit of transformer 215,216 are connected with Fig. 2 A, Fig. 2 B, Fig. 3, Fig. 4 A, Fig. 4 B, any one the 1st sparking electrode 12a of Fig. 8～Figure 11, the 1st induction electrode 12b, the 2nd sparking electrode 13a, the 2nd induction electrode 13b respectively.The transformer of primary-side circuitry drives with switch element 212 conductings, and the NE BY ENERGY TRANSFER of primary side is to secondary coil 215b and secondary coil 216b, pulsing shape voltage.Have, each secondary coil and each electrode connect into again: be applied to the polarity of the voltage between the 1st sparking electrode 12a and the 1st induction electrode 12b and be applied to the 2nd sparking electrode 13a and the 2nd induction electrode 13b between the polarity of voltage opposite.
