The specific embodiment
It is following that the present invention will be described in detail with reference to drawings and Examples.
Fig. 2 is the ideograph of the part of the air purifier in one embodiment of the invention.
As shown in the figure, ionization part 10 is arranged on the previous section of air purifier, wherein will connect high voltage, and foreign substances such as airborne dust 40 are carried out ionization.The structure of ionization part 10 can be made of an electrode (sparking electrode) and corresponding with it another electrode (sparking electrode), and there is no particular limitation but its shape is with size.In order to enlarge the ionized space of ionization part 10, an electrode in sparking electrode and the counter electrode can be constituted the electric wire shape, another then constitutes mesh-shaped, perhaps also two electrodes all can be constituted the electric wire shape, as above will connect the high voltage of power supply unit 30 in the ionization part 10 that shape constitutes.
In the present invention, also static flocking fibre can be set on the electrode of ionization part, in the case, foreign substances can obtain 1 time by the fiber of flocking and filter under situation about being ionized.
And the back of ionization part 10 can add installs after-filter 21, can use the electrode of mesh-shaped in the after-filter, preferably is pasted with static flocking fibre on its electrode surface.In the present invention, will in being pasted with the after-filter of static flocking fibre, connect high voltage, and make static flocking fibre pass through dust in the electrostatic means filtered air.
In addition, dust collecting part 20 is made of an electrode 22 at least, preferably is pasted with static flocking fibre 23 in the electrode 22.To connect high voltage in the dust collecting part 20, by ionization part 10 being ionized and move to dust 41 of dust collecting part 20 etc., will be adsorbed onto in the static flocking fibre 23 by electrostatic force.Static flocking fibre also can contact dust in the absorbed air by physical property, thereby can further increase the filter efficiency of air purifier except having the electrostatic force suction-operated.Thus, carry out to comprise hardly in the filtered air particle 42 foreign substances such as dust by air purifier.
The electrode 22 of dust collecting part is preferably the electrode of mesh-shaped, and the electrode of mesh-shaped can form static flocking fibre in its surface easily, and makes smooth and easy the flowing of air of removing dust etc. owing to having through hole.
Fig. 3 is the enlarged drawing of ' A ' portion among Fig. 2, and it is the ideograph of the shape of the fiber 23 that is pasted with electrostatic spinning on the surface of mesh electrode 22.As shown in the figure, be adsorbed with dust particle 41 on the static flocking fibre 23, the split pole row who has utilized static flocking fibre in the dust filter method is to characteristic.
Below, with reference to the accompanying drawings 4, to the split pole row of static flocking fibre to describing.Fig. 4 is the ideograph that electrostatic spinning filters.As shown in the figure, the fiber 53 of flocking is set between tabular two electrodes 51,52, and when connecting voltage in electrode, the split pole row who produces fiber by electrostatic force is to phenomenon B, and the fiber 54 of split pole will move to circuit board 60.Wherein, be pre-formed adhesive layer 61 on the surface of circuit board 60, and fixing above-mentioned mobile fiber 55.
Fig. 5 is the ideograph that is fixed on the static flocking fibre 55 on the circuit board 60 by adhesive layer 61.As shown in the figure, the static flocking fibre of pasting on the circuit board 60 55 be in split pole row to state, it can continue by outside electrical forces to keep the split pole state, and under the split pole state, static flocking fibre 55 can be by the particles such as dust of being ionized of electrostatic means absorption.Fig. 6 points out out reality evenly distributed state that static flocking fibre is arranged on the surface of mesh electrode.
In air purifier of the present invention, static flocking fibre also will filter dust etc. by the physical property contact except filter dust etc. by electrostatic means, therefore, need control the form of static flocking fibre.
When thicker and length is longer at static flocking fibre, can increase the physical property contact effect of static flocking fibre, and, according to the length of static flocking fibre, can draw the difference on the discharge current characteristic as shown in table 1 below.
The discharge current characteristic of [table 1] static flocking fibre length correspondence
| Connect voltage (kV) | Discharge current | ||
| Not carrying out electrostatic spinning handles | 0.4mm fiber | 0.7 |

| 5.5 | 170 | 210 | 220 |
| 6 | 300 | 370 | 380 |
According to the result of table 1, when comparing, including under the situation of static flocking fibre with the situation of not carrying out the electrostatic spinning processing, the discharge current of the connection voltage correspondence that it is identical is bigger.Particularly, when comparing with the situation of the length of static flocking fibre being made 0.4mm, the discharge current under the situation of its length being made 0.7mm is bigger.According to aforesaid result, in the structure member of air purifier, form under the situation of static flocking fibre, can carry out filter operation by electrostatic force, and long more in the length of static flocking fibre, it is also good more by the effect that electrostatic force filters.
Variation with reference to the discharge current of the voltage change correspondence in the accompanying drawing 7 can be from visually understanding the result of table 1.
Fig. 8 is the photo of the air purifier of exemplary actual fabrication.Air purifier among the present invention is except can be used as independently product, and the auxiliary equipment that also can be used as conditioners such as air-conditioner provides.Because it is technique known in the relevant industries that the structure of air purifier is installed in the air-conditioner, will save its specific description at this.
Below the air cleaning performance of the air purifier among the present invention is tested, wherein, the sparking electrode of ionization part is made of metal cords, counter electrode then carries out the sheet metal that electrostatic spinning handles by sheet metal or surface and constitutes; After-filter uses Al mesh electrode or use to comprise the mesh electrode of the fiber of electrostatic spinning; Use sheet metal or use to comprise the mesh electrode of the fiber of electrostatic spinning in the dust collecting part.
And, connected voltage in the ionization part, after-filter and dust collecting part are then carried out ground connection or have been comprised the situation of disconnecting electric field.
The test result of the air cleaning performance among the present invention is as shown in table 2 below, as shown in table 2, comprises in electrode under the situation of static flocking fibre, and its air cleaning performance is comparatively outstanding substantially.With do not carry out can improving about air cleaning rate more than 20% when in electrode, comprising static flocking fibre under the situation that example that electrostatic spinning handles compares.
