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, between the discharge electrode (64) and the corresponding utmost point of discharge (66), produce power line (67), make and be included in dust in air in way through 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.
