[formation of filter component]

Filter component 230 is arranged on the inside of shell 210, is used for removing the fine particle that room air contained that sucks from each air entry 213,214,216.As shown in Figure 6, filter component 230 has following each several part: coarse filter 231, plasma ionization part 232, sterilizing filter 233, anti-phase lamp 235.The structure of filter component 230 is coarse filter 231, plasma ionization part 232 and sterilizing filters 233 that the feasible room air that sucks from each air entry 213,214,216 passes through filter component 230 inside successively.

Coarse filter 231 is to be used to remove the filter that is sucked airborne bigger dust in the shells 210 etc. by wind pushing mechanism 220.Coarse filter 231 has filter screen part 310 and framework 311 (referring to Fig. 8).Filter screen part 310 is wire resin web made from polypropylene (hereinafter, being referred to as PP), and the bigger dust that is contained in the air in the suction shell 210 etc. are all attached to above it.In addition, the fiber of formation filter screen part 310 is by the fuse 310a that constitutes with PP and also is that the clad 314 that constitutes with PP is equally made.On clad 314, have and expose photochemical catalyst 312 and catechin 313 (referring to Fig. 9) aerial, the visible light line style.Contain titanium oxide in the photochemical catalyst 312 of visible light line style, in order to remove mushroom or virus attached to mould that is contained in the dust on the filter screen part 310 and germ etc. by visible rays exciting light catalyst action.Catechin is a kind of in the polyphenol, is epicatechin, table unstrained spirits catechin, epicatechin unstrained spirits hydrochlorate, the general name of table unstrained spirits catechin unstrained spirits hydrochlorate etc.This catechin can suppress the breeding of mushrooms such as the mould that contained attached to the dust on the filter screen part 310 etc. or germ, can suppress the activity (referring to Fig. 9) of virus.

Plasma ionization part 232 can make by the dust that is contained in the air after the coarse filter 231 etc. and have very strong electric charge.Because this charged, improved on the electrostatic filter 330 of sterilizing filter 233 arresting efficiency to dust etc.In addition, because virus or germ that this plasma ionization part 232 also makes in the dust to be contained are charged, thus can improve the efficient of on photocatalytic apatite described later viral adsorption or germ, and then raising is except that the efficient of virus removal or germ.

Sterilizing filter 233 is filters of ring-type, and as shown in Figure 6, it is on the excircle of first roller 241 and second roller 242, by these two roller supportings.In addition, above-mentioned first roller 241 is fixed on the shell 210, can rotate.In addition, second roller 242 is by the not motor-driven of expression rotation (referring to the arrow M3 among Fig. 6) among the figure.In addition, in the bottom of second roller 242, the rinse bath 245 of the rinse water 247 that being provided with is used to pack into cleans sterilizing filter 233.In addition, can reduce flowing of air, can also sterilizing filter 233 desiccant small-sized fanses 237 be set in the downstream of sterilizing filter 233 side in this case because worry sterilizing filter 233 is immersed in the cleaning fluid.

The part sectional drawing of having represented sterilizing filter 233 among Figure 10.This sterilizing filter 233 has electrostatic filter 330 and optical catalyst filter 331.By electrostatic filter 330 and optical catalyst filter 331 are piled up, formed sterilizing filter 233.When sterilizing filter 233 arrives the upstream side of airflow direction, electrostatic filter 330 is positioned on the position of air stream upstream side, in addition, when sterilizing filter 233 arrived the upstream side of airflow direction, optical catalyst filter 331 was positioned on the position in downstream of air stream.Electrostatic filter 330 is adsorbed in the plasma ionization part 232 with electric dust etc.Dusts by electrostatic filter 330 etc. are then attached on the optical catalyst filter 331.Photocatalytic apatite 334 after on the opposite side surface of optical catalyst filter 331, replacing with calcium atom in the calcium hydroxide apatite and titanium atom.This photocatalytic apatite 334 can adsorb and remove virus or mould, the germ etc. that dust etc. is contained.In addition, this photocatalytic apatite 334 can also adsorb and decompose the Ammonia that is contained in the air by optical catalyst filter 331, (referring to Figure 11) such as aldehydes 336 and oxynitrides 337.

Anti-phase lamp 235 is arranged in the centre of sterilizing filter 233.This anti-phase lamp 235 is that ultraviolet ray is radiated at lamp on the optical catalyst filter 331 of sterilizing filter 233, and it can activate the photochemical catalyst on each optical catalyst filter 331.

[feature of air cleaner]

Sterilizing filter 233 in the air cleaner 201 among second embodiment carries out ring-type and moves, and cleans with cleaning fluid 247.Like this, in this air cleaner 201, just can discharge the inorganic matter that is deposited on the optical catalyst filter 331 energetically.Therefore, in this air cleaner 201, can keep removing the effect of virus removal or germ for a long time.

[modified example]

In a second embodiment, be that the utility model is applied in the air cleaner 201, but, the utility model also can be applied to as shown in figure 12 warm oneself and the air conditioner 400 of refrigeration in.

This air conditioner 400 is to be used for being supplied to indoor device through the air that is in harmonious proportion, and it has the indoor set 401 that is installed on indoor wall and so on and is arranged on outdoor off-premises station 402.Indoor set 401 is provided with the air entry 405 that is used in the indoor air suction air conditioner 400, in the inboard of this air entry 405 the filter component (not shown) is housed.The utility model is being applied under the situation of this filter component, also can be used for removing attachment removal or be adsorbed on virus and mould on the filter component, germ etc., and prevent to produce stink and cause air pollution.

Air cleaning system of the present utility model and air cleaning unit can be brought into play the effect except that virus removal or germ for a long time constantly, can merge with air-conditioning system to use.
