所を考慮する必要があった。When the ultraviolet radiation lamp is turned on, the photocatalyst of the honeycomb adsorber in the portion irradiated with the ultraviolet light is excited, and the substance adsorbed on the honeycomb adsorber is excited.
For example, acetaldehyde (CH 3 CHO) is finally decomposed into carbon dioxide (CO 2 ) and water (H 2 O).
However, during the decomposition, an intermediate product such as acetic acid (CH 3 COOH) is generated and causes an unpleasant odor. In order to prevent the intermediate product from being adsorbed and leaving the room, another honeycomb adsorbent is required. Will be needed. Further, since ultraviolet rays easily leak to the outside from the ventilation holes of the honeycomb adsorbent, it is necessary to consider the installation location of the air cleaning device.

内へ吹き出される。Means for Solving the Problems [1] By operating the blower, an air flow from the air inlet to the air outlet is generated in the casing, and the room air is introduced into the casing from the air inlet.

吸着作用が維持されて中間生成物を吸着するので、異臭
の外部放出が防止できる。The excitation light source is arranged so that the light flux of the excitation light source is obliquely incident on the ventilation holes of the honeycomb adsorbent. This makes it difficult for the light from the excitation light source to leak out of the honeycomb adsorbent through the air holes. Then, since the regeneration is performed in the portion of the vent hole where the light of the excitation light source is irradiated, the substance adsorbed on the honeycomb adsorbent is decomposed into harmless substances such as CO 2 and H 2 O. Intermediate products giving off-flavors are formed. However, in the portion of the ventilation hole where the light of the excitation light source is not irradiated, the adsorbing action of the honeycomb adsorbing body is maintained without adsorbing the intermediate product and the intermediate product is adsorbed.

For this reason, the honeycomb adsorbent is
In addition to being removably arranged in the casing, the arrangement direction is changed every time a predetermined period elapses, the front end face and the rear end face are reversed, and the unactivated portions are activated (see FIG. 4).

For this reason, since the volume of the end portion of the honeycomb adsorber can be made larger than that of other shapes, the intermediate product can be surely adsorbed and the external emission of the off-odor can be prevented. Further, when the arrangement direction of the honeycomb adsorbent is changed, the end of the adsorbent farther from the excitation light source and the end of the adsorber closer to the excitation light source can be accurately exchanged, and the activation can be reliably performed.

る。[0011] The angle formed between the light flux and the inner surface of the vent hole increases toward the end of the honeycomb adsorbent farther from the excitation light source, so that the light of the excitation light source is transmitted deeper into the vent hole (toward the front end face). ), It becomes difficult to reach, so that the portion that is not activated increases. For this reason, the excitation light sources are arranged in two places so that the light flux of the excitation light sources obliquely enters the ventilation holes of the honeycomb adsorber from two different directions, and the switching means provides:
The excitation light source to be activated is changed alternately every time a predetermined period elapses. Thereby, the non-activated portion can be activated without replacing the honeycomb adsorbent.

２１から車室内への漏れが防止できる。Since the air purifying apparatus A of this embodiment has a structure in which adsorption and regeneration are performed simultaneously, the UV LED 4 is lit while the operation switch of the air purifying apparatus A is turned on. Since the UVLEDs 4 are arranged in the casing 1 on the upstream side of the honeycomb activated carbon 2 so that the luminous flux 41 is obliquely incident on the ventilation holes 21 of the honeycomb activated carbon 2, as shown in FIG. The light enters the pores 21. Thereby, the light flux 41 can be prevented from leaking into the vehicle interior from the vent hole 21 of the honeycomb activated carbon 2.

It is decomposed into harmless substances such as carbon (CO 2 ) and water (H 2 O), but produces an intermediate product such as acetic acid (CH 3 COOH) which emits an off-flavor during the decomposition. However, in the portion of the ventilation hole 21 not irradiated with light, regeneration is not performed, and the adsorption action of the honeycomb activated carbon 2 is maintained to adsorb the intermediate product.

する（図４参照）。As the distance from the UVLED 4 to the end of the honeycomb activated carbon 2 (the lower side in the figure) increases, the angle formed between the light flux 41 and the inner surface of the ventilation hole 21 increases, and light reaches the inside of the ventilation hole 21 (toward the front end surface). Because it becomes difficult, the portion that is not activated (the portion other than the two-dot chain line in FIG. 3) increases. For this reason,
When the air cleaning device A is used for about one month, an operation for changing the arrangement direction of the honeycomb activated carbon 2 is performed to reverse the front end face 22 and the rear end face 23 to activate the unactivated portions (FIG. 4). reference).

At the end of the honeycomb activated carbon 2, the angle formed between the light flux 41 and the inner surface of the vent hole 21 becomes small, so that light reaches the inside of the vent hole 21 (toward the front end surface) and regeneration occurs on the entire surface of the vent hole 21.
Since the luminous intensity is low (see FIG. 3A) and the decomposing power is low, the adsorbing action of the honeycomb activated carbon 2 is maintained and the intermediate product is adsorbed, so there is no problem.

[A] Regeneration is performed in the portion of the ventilation hole 21 where the light of the UVLED 4 is irradiated (the two-dot chain line portion in FIG. 3), and a substance such as acetaldehyde (CH 3 CHO) adsorbed on the honeycomb activated carbon 2 is converted into carbon dioxide (CO 2). 2 ) It is decomposed into harmless substances such as water (H 2 O). An intermediate product such as acetic acid (CH 3 COOH) that emits an odor during the decomposition is formed. However, since the UVLEDs 4 are arranged so that the luminous flux 41 enters the ventilation holes 21 of the honeycomb activated carbon 2 from an oblique direction,
In the portion of the ventilation hole 21 not exposed to light, the regeneration is not performed, and the adsorbing action of the honeycomb activated carbon 2 is maintained to adsorb the intermediate product, so that it is possible to prevent the emission of an odor into the vehicle interior.

It is removably disposed in the casing 1 near the air outlet 12. The rectangular parallelepiped is honeycomb activated carbon 2
Since the volume of the end portion can be increased, the intermediate product is excellent in adsorbing property, and it is possible to reliably prevent the emission of an odor into the vehicle interior due to the regeneration. In addition, since the honeycomb activated carbon 2 is a rectangular parallelepiped, when the disposing direction is changed, the adsorber end farther from the UVLED 4 and the adsorber end closer to the UVLED 4 can be exchanged accurately, and the activation can be reliably performed. Can be.
