施の形態ではランプ等と一体で設けられている。In FIG. 1, an ultraviolet lamp 7 is a cold-cathode tube type discharge lamp, and a fluorescent material is coated inside the tube.
A rare gas mixture and an appropriate amount of mercury are enclosed.
It emits light including ultraviolet rays in the near ultraviolet region having a peak around 65 nm. Reference numeral 7a denotes a protective tube for protecting the ultraviolet lamp 7, which prevents a decrease in the amount of light (brightness) due to the direct cooling of the ultraviolet lamp 7 by the wind from the blower 10, and also prevents the air purifier from being damaged due to damage to the lamp.

ない。When photocatalytic deodorization is used in an air purifying device, even if the deodorizing section is provided after a high-performance dust collecting filter, a fat or oil component or the like on the surface of a reflecting plate or the surface of an ultraviolet lamp can be obtained due to long-term use. It is unavoidable that dust and dirt such as cigarette dust gradually adhere, but adhere with time.

することが可能になる。Such dirt causes a decrease in the reflection efficiency to the photocatalyst-attached adsorbent and a decrease in the irradiation light from the light source, resulting in a decrease in deodorization efficiency and insufficient regeneration of the photocatalyst-adsorbent itself. This also affects the life of the deodorizer.
In order to cope with such a conventional problem, the photocatalyst layer 8a carried on the surface of the reflector 8 is irradiated with ultraviolet rays to excite the photocatalyst, and the oil or fat adhered to the inner surface of the reflector by a photocatalytic reaction (oxidation-reduction reaction). Since the organic substances such as components are oxidized and decomposed to remove dirt, it is possible to always maintain the reflection plate in a good state.

2 eV, which corresponds to a wavelength of 380 nm. The energy of this 380 nm wavelength photon is about 36000
It is equivalent to the thermal energy of K (in a photocatalytic reaction, the energy of each photon is the same regardless of the intensity of light), so even under the weakest ultraviolet light, the surface of titanium oxide is contaminated by this high-temperature thermal energy. It oxidizes such organic substances and decomposes them into carbon dioxide and water.

果が期待できる。As shown in FIG. 5, the emission spectrum of the light emitted from the light storage film has a peak at a wavelength of 410 nm, and ultraviolet light is generated together with a relatively short wavelength visible light. 6 is irradiated for a long time. Near ultraviolet rays having a wavelength of 300 to 410 nm are particularly effective for activating the photocatalyst. However, titanium oxide (TiO 2 ) as a photocatalyst has a band gap slightly changed by adjusting the impurity concentration. Photocatalysis may occur even with visible light having a relatively short wavelength, and a sufficient deodorizing effect can be expected even with a light emission (emission) spectrum emitted from the light storage film after the ultraviolet lamp is turned off as shown in FIG.

The reflecting member 9 reflects the light leaking upward from the ultraviolet lamp 7 through the honeycomb hole of the adsorbent with photocatalyst 6 and irradiating the light on the back surface of the adsorbent with photocatalyst 6 again.
Since the light leaking out of the main body is reduced as much as possible, it is effectively used for activating the back surface of the adsorbent 6 with the photocatalyst, which has not been sufficiently irradiated with light and the adsorbed odor component has not been sufficiently decomposed. A high deodorizing effect can be obtained, and the downsizing of the adsorbent 6 with a photocatalyst can be expected.

Even after the ultraviolet lamp 7 is turned off (or after the ultraviolet lamp 7 is turned off only by intermittent on / off), the irradiation of the back surface of the adsorbent with photocatalyst 6 with the light containing the ultraviolet light can be continued for a considerable time, Since the regeneration of the back surface of the adsorbent 6 with a photocatalyst is further improved without increasing power consumption, a high deodorizing effect can be maintained for a long time.
