The specific embodiment
Below with reference to back accompanying drawing paper, embodiments of the invention are elaborated.
As shown in Figures 2 and 3, the air purifier of present embodiment mainly comprises casing 52, sucks grid 54, pressure fan 56, air cleaner 58, electric formula dust-collecting filter 60, high-voltage generator 91, light catalyst filter 92 and dividing plate 94.Above the outlet 51 that casing 52 will be discharged air was formed on, the front was open; Suction grid 54 is combined in the front of casing 52, is formed with the suction inlet 53 that sucks air; Pressure fan 56 is installed in the inside of casing 52, makes the air purifier air outside carry out forced circulation towards the inside of casing 52; Air cleaner 58 is arranged on the back side that sucks grid 54, and the bigger dust of airborne volume that is inhaled into is filtered; Electricity formula dust-collecting filter 60 is arranged on the rear of air cleaner 58, utilizes high voltage that the dust in air that is inhaled into is carried out ionization and collects; High-voltage generator 91 imposes on electric formula dust-collecting filter 60 with high voltage; Light catalyst filter 92 is arranged on the rear of electric formula dust-collecting filter 60, makes the luminous energy by producing in electric formula dust-collecting filter 60 activate the titanium oxide that is coated on the dictyosome, plays the effect of catalyst deodorizing; Dividing plate 94 is divided into the plenum chamber that is formed with pressure fan 56 with the inner space of casing 52 and is formed with the filter chamber of electric formula dust-collecting filter 60 and light catalyst filter 92, is formed with wind pushing hole 93 in the central authorities of dividing plate 94.
As shown in Figure 4 and Figure 5, electric formula dust-collecting filter 60 is made of ionization part 61 and collection unit 70.61 pairs of dust in air of ionization part are carried out ionization; Collection unit 70 is arranged on the rear of ionization part 61, and the dust that is ionized is collected.
Wherein, passive electrode 74 is made of zigzag aluminium strip, the twist up shape; Accelerating electrode 76 is made of aluminium strip, and twist up shape and passive electrode 74 are arranged alternately.
In addition, the 1st megohmite insulant 77 applies film forming with poly terephthalic acid ethanol ester (PET), surrounds the surface of accelerating electrode 76.
On the one hand, the 2nd megohmite insulant 78 is made of poly terephthalic acid ethanol ester (PET), and forms band shape, is rolled into the twist up shape simultaneously, and be arrangeding in parallel with passive electrode 74 and accelerating electrode 76 forms.When because the function of safety device when making that the 1st megohmite insulant 77 is impaired, is played in thermalization, play the collecting action of the dust that absorption quickens by accelerating electrode 76 simultaneously.
Below the work of the present invention with said structure is described.
At first, drive pressure fan 56, then indoor air filters the bigger foreign matter of volume through sucking the suction inlet 53 and the air cleaner 58 of grid 54; Through electric formula dust-collecting filter 60, collect the dust in air that is ionized; Carry out after the deodorizing through light catalyst filter 92,, discharge towards the outside of air purifier by the outlet 51 of casing 52.
Below the collection process through the koniology of above-mentioned electric formula dust-collecting filter is further described in detail.(consulting Fig. 4)
The high voltage of 5～7Kv is imposed on the discharge electrode 64 of ionization part 61, then discharge electrode 64 produces discharge, at the discharge electrode 64 and the generation power line 67 between the corresponding utmost point 66 that discharges, make and be included in dust in air in the process way of power line 67, make dust particle and the electronics that in ionization part 61, produces take place to collide and be ionized, flow into collection unit 70 then.
At this moment, the high voltage of 2～3kv is imposed on the accelerating electrode 76 of collection unit 70, make accelerating electrode 76 have identical polarity with the dust that is ionized.That is to say that the dust particle that flows into towards the space between accelerating electrode 76 and the 2nd megohmite insulant 78 quickens by accelerating electrode 76, dust B absorptive collection is on the 2nd megohmite insulant 78; The dust particle that flows into towards the space between the 2nd megohmite insulant 78 and the passive electrode 74 quickens by accelerating electrode 76, and dust C is adsorbed and is collected on the passive electrode 74.
Up to the present, though be that the center has been described in detail to embodiments of the invention, the personnel that have general knowledge in the technical field of the invention can propose a lot of distortion in basic fundamental thought range of the present invention.Basic fundamental thought of the present invention is embodied in the patent request scope, and all distortion in the equal with it scope all should be interpreted as belonging in the scope of the present invention.
The effect of invention
In sum, the invention provides the electric formula dust-collecting filter of the air purifier that can bring following effect:
The first, make the 2nd megohmite insulant independent separation setting be coated with from the teeth outwards the 1st megohmite insulant Between accelerating electrode and the passive electrode, even because thermalization so that the insulation of the 1st megohmite insulant destroyed, Also can reduce because the fraction defective that the insulation breakdown of the 1st megohmite insulant causes prolongs by the 2nd megohmite insulant Grown the life-span.
The second, because dual the 1st megohmite insulant and the 2nd megohmite insulant of having formed improved insulating properties.
The 3rd, by the dust that accelerating electrode accelerates, be collected in passive electrode and the 2nd megohmite insulant On, increased the collection area of dust, improved capacity gauge.
