なるという欠点を有していた。2. Description of the Related Art Conventionally, for example, an air purifier as shown in the external view of FIG.
As disclosed in JP-A-304427, it is manufactured solely for the purpose of collecting dust particles in the air, and is additionally manufactured for additional deodorization. However, such a conventional air purifier has the following problems.
One was that it was not possible to remove strong odor components in the air. The other is that there are a lot of airborne bacteria and germs that are floating in the air due to coughing, squeezing, talking, etc., but these could hardly be removed. . In order to solve the above-mentioned conventional problems, as shown in FIGS. 1 and 5, a dust collecting filter 5 is provided in an air passage 4 connecting a suction port 2 and a discharge port 3 formed in a main body housing 1.
And a deodorizing filter 6 using activated carbon and a blower 7, and on the leeward side of the deodorizing filter 6, an ultraviolet lamp 8, around the ultraviolet lamp 8, and titanium oxide excited by the ultraviolet lamp 8 as a base material. An air purifier provided with a photocatalyst section 9 formed of a meshed photocatalyst layer held by the air purifier has been invented. The dust collecting filter 5 has a characteristic that it can remove dust and smoke having relatively large particles, but cannot remove a gaseous substance causing a bad odor or a high boiling substance having relatively small particles. The deodorizing filter 6 using the activated carbon can remove a substance having a high polarity, a substance having a high boiling point, and a substance having a high concentration and a small polarity, but remove a substance having a low concentration and a small polarity and a substance having a low boiling point. They have the property that they cannot do it. Further, the photocatalyst layer has a characteristic that it easily adsorbs a substance having a small polarity or a substance having a low boiling point, and its performance is deteriorated by the adhesion of a substance having a small polarity or a substance having a high boiling point. Therefore, in the above configuration, when dust, smoke, high-concentration small-polarity substance, high-polarity substance, or high-concentration high-boiling point substance passes through, the dust collection filter 5 and the deodorizing filter 6 using activated carbon adsorb. However, when the concentration of a substance having a small polarity, a substance having a large polarity, or a substance having a high boiling point decreases, these are released from the deodorizing filter 6 using activated carbon, and the photocatalyst portion 9 formed of a photocatalyst layer is formed. , And adhere to the photocatalyst section 9, so that the performance of the photocatalyst layer is deteriorated and the original deodorizing effect cannot be exhibited.

If the indoor air is dirty with cigarette smoke, etc.
The rotation of is increased to increase the air volume, so that the particulate components such as cigarette tar and the like are not diffused to the photocatalyst unit 9 covered by the cover 10 but are collected by the dust collection filter 5, so that the photocatalyst unit 9 is prevented from being stained. Can be. Then, when the amount of dust, smoke, and odor components in the air decreases, the amount of air flowing through the cover 10 decreases, and the gas, which is the odor component, is diffused to the photocatalyst unit 9 covered by the cover 10, It is efficiently deodorized in the part 9.
