[feature of air cleaner of the present invention]
(1) in the air cleaner in the past, is adsorbed on virus that the dust etc. of the wet end of prefilter had or mycete, antibacterial etc. and adheres to always and intersperse among wet end, carry out the cleaning of prefilter up to user of air cleaner etc.So in the air cleaner in the past, virus can be discharged once more, perhaps mycete or antibacterial etc. may breed at wet end, and become stench or air-polluting reason.
And in the air cleaner 1 of the present invention, on the wet ends 310 attached to prefilter 31 such as the big dust that contains in the room air.So the virus that is had attached to dust of wet end 310 etc. or mycete, antibacterial etc. are replied type photocatalyst 312 by visible light and remove.Therefore, this air cleaner 1 need not to clean continually prefilter 31 and can suppress to cause stench or air pollution.
(2) in the air cleaner in the past, be adsorbed on virus that dust on the filter etc. had or mycete, antibacterial etc. and adhere to always and intersperse among wet end, carry out the replacing of filter up to user of air cleaner etc.So in the air cleaner in the past, virus can be discharged once more, perhaps mycete or antibacterial etc. may breed at wet end, and become stench or air-polluting reason.
And in the air cleaner 1 of the present invention, the dust that contains in the air etc. are attached on the photocatalyst filter membrane 331.So the virus that is had attached to dust on the photocatalyst filter membrane 331 etc. or mycete, antibacterial etc. are adsorbed by photocatalytic apatite 334 and remove.Therefore, this air cleaner 1 need not to change continually the 1st optical catalyst filter 33 and can suppress to cause stench or air pollution.
In addition, in the air cleaner 1 of the present invention, airborne virus or mycete, antibacterial etc. are replied type photocatalyst 312 by visible light or photocatalytic apatite 334 is removed.Therefore, this air cleaner 1 can easily remove virus removal or mycete, antibacterial etc.
(3) in the air cleaner 1 of the present invention, the area load visible light of the wet end 310 of prefilter 31 is replied type photocatalyst 312.Therefore, the light time in wet end 310 projection chamber, activated the photocatalyst effect of photocatalyst 312.Promptly need not to prepare special light source and just can remove virus removal or mycete, antibacterial etc.Therefore, this air cleaner 1 just can remove virus removal or mycete, antibacterial etc. with simple structure.
(4) in the air cleaner 1 of the present invention, the wet end of prefilter 31 310 is made of fiber.And this fiber is made of core 310a and coating 314.In addition, this coating 314 contains photocatalyst 312 and retaining part photocatalyst 312 is exposed to air side.
In general, in order to make fiber-loaded photocatalyst, the method that adopts is to carry out the powder body of photocatalyst etc. injection-molded etc. with dispersive state in resin usually.But such fiber slowly worsens in the irradiation again and again at the light that the described photocatalyst of initiation carries out the wavelength of catalytic reaction.Therefore, the filter that is made of such fiber has lost intensity at leisure.Usually, if sneak into foreign body in the resin, the problem that also exists this object to be easy to become fragile.
But, there is core 310a in this fiber 310, have only coating 314 loaded optic catalysts 312.So though coating 314 slowly worsens in the irradiation again and again at the light that the described photocatalyst 312 of initiation carries out the wavelength of catalytic reaction, core 310a does not worsen because of the irradiation of light.In addition, do not sneak into foreign body (photocatalyst) among this core 310a, so its intensity also is excellent.Like this, this prefilter 31 can keep its intensity for a long time.
(5) in the air cleaner 1 of the present invention, the area load photocatalytic apatite 334 in the downstream of the air flow of photocatalyst filter membrane 331.In the past photocatalyst filter membrane uses the mixture of adsorbent such as zeolite and titanium dioxide etc.On the one hand, known apatite is to the characterization of adsorption height of virus or bacterium, so made the structure that replaces the photocatalyst filter membrane of former form with apatite in order to improve the effect of degerming portion.But, even adopt such structure, also only effective to the virus or the bacterium that are adsorbed near the titanium dioxide with catalyst performance, and be adsorbed in apatite but do not have the virus of titanium dioxide or bacterium not to be removed near it, cause these viruses or bacterium still to remain on the apatite, so worry after long-time, can cause stench or air pollution etc.But in this photocatalytic apatite 334, absorption position itself just has the photocatalyst performance, so almost can remove the virus or the bacterium of absorption fully.Therefore, need not to clean continually or change this photocatalyst filter membrane 33 1 and can suppress to cause stench or air pollution.
(6) in the air cleaner 1 of the present invention, the 1st catalyst filter 33 is arranged on the downstream of the air-flow direction of plasma ionization portion 32.In addition, the 1st catalyst filter 33 loaded optic catalyst apatite 334.
Viewpoint on the chemical constitution thinks that apatite has electric charge, and it has the ability that forms hydrogen bond or ionic bond with other materials.In addition, virus or bacterium are made of sugar chain or protein etc., so have faint electric charge.Apatite has strong absorbability to virus or bacterium, and this strong absorbability is considered to the result of charge effect between the two.
Be that air cleaner 1 of the present invention has adopted above-mentioned formation, therefore, virus or bacterium are endowed stronger electric charge in plasma ionization portion 32 before being filtered the device capture.Thereby, make that virus or bacterium are easier to be adsorbed by photocatalytic apatite 334.Its result can improve the arresting efficiency to virus or bacterium.In addition, this photocatalytic apatite 334 has the performance except that virus removal or bacterium.Therefore, this air cleaner 1 need not to clean continually or change to suppress to cause stench or air pollution.
(7) in the air cleaner 1 of the present invention, the photocatalytic apatite 334 with photocatalyst effect is carried on the surface in downstream of the air flow of photocatalyst filter membrane 331.The air that promptly contains the not adsorbable virus of photocatalyst filter membrane 331 or mycete, antibacterial etc. can contact photocatalytic apatite 334.Its result, these viruses or mycete, antibacterial etc. are adsorbed on photocatalytic apatite 334, and then, photocatalytic apatite 334 is removed.Be photocatalytic apatite 334 when removing virus removal or mycete, antibacterial etc., reduced because of adhered dust on the photocatalyst filter membrane 331 etc. and covered from the ultraviolet probability of conversion lamp 35 directive photocatalytic apatites 334.So photocatalytic apatite 334 has obtained removing the abundant irradiation of the required light of virus removal or bacterium, and then photocatalytic apatite 334 can remove more virus or mycete, antibacterial etc.Therefore, this air cleaner 1 can further suppress to cause stench or air pollution.
(8) in the air cleaner 1 of the present invention, catechin 313 is carried on the fiber surface of the wet end 310 that constitutes prefilter 31.In general, catechin has the effect of excellent inactivation of viruses or suppresses the effect of the breeding of bacterium.So, can further suppress breeding attached to mycete on the wet end 310 or antibacterial etc., thus inactivation of viruses more effectively.Therefore, this air cleaner 1 can further suppress to cause stench or air pollution.
(9) in the air cleaner 1 of the present invention, catechin 313 is rubbed among the PP, and then be formed the PP surface institute load of wet end 310.So catechin 313 is difficult to peel off from wet end 310.Therefore, even the user of air cleaner 1 etc. clean prefilter 31 in order to clean prefilter 31, catechin 313 can not peeled off from wet end 310 fully yet.
