一緒に車室内に入って快適性を損ねるおそれがある。However, none of the publications described in these publications has an evaporator provided with a photocatalyst. For this reason, there is a problem that bacteria and the like easily propagate in the evaporator. That is, in the air conditioner for a vehicle, the moisture in the blown air condenses when being cooled by the evaporator and adheres to the surface of the evaporator. For this reason, the surface of the evaporator becomes wet with condensed water, and bacteria easily propagate there. When bacteria proliferate, a large amount of odorous substances are generated due to their metabolism and the like, and may enter the vehicle interior together with the blast air to impair comfort.

る。The operation of the vehicle air conditioner M configured as described above will be described. The ultraviolet lamp 50 is turned on at all times during the operation of the blower 20 or periodically at intervals. Thereby, ultraviolet rays are simultaneously emitted toward the deodorizing filter 32 on the upstream side of the lamp 50 and the evaporator 40 on the downstream side. The photocatalyst 34 of the deodorizing filter 32 is irradiated with the ultraviolet rays radiated toward the deodorizing filter 32.
Are excited to generate OH radicals. These OH radicals decompose odor substances adsorbed on the adsorbent 33. That is, the OH radical here is an “odor decomposition substance” in the claims. Thereby, the adsorbent 3
3 is activated, and the ability to adsorb odorous substances is restored.

物質が入って快適性を損ねることがない。On the other hand, the ultraviolet rays emitted toward the evaporator 40 excite the photocatalyst 41 of the evaporator 40 to generate OH radicals. Bacteria on the surface of the evaporator 40 are killed by the OH radicals.
That is, the OH radical here is a “bactericidal substance” in the claims. Sterilization is also performed by directly irradiating the bacteria with the ultraviolet rays. Therefore, on the downstream side of the deodorizing filter 32, no new odor substance is generated due to the metabolism of bacteria or the like, and the odor substance does not enter the vehicle interior and the comfort is not impaired.

And the photocatalyst 41 can cause a catalytic action. Therefore, it is not necessary to separately provide the ultraviolet lamp 50 for each of the photocatalysts 34 and 41.

That is, the photocatalyst 41 made of a metal oxide such as titanium oxide has higher hydrophilicity than the evaporator 40 made of aluminum. Therefore, it is possible to prevent water droplets attached to the surface of the evaporator 40, that is, the water droplets attached to the photocatalyst 41 from being blown off by wind pressure and entering the vehicle interior together with the cool air.

The paint 60 is applied to the inner peripheral surface between 0 and 0. The paint 60 is also applied to the surface of the lining 49. A photocatalyst 61 made of a metal oxide powder such as titanium oxide or zinc oxide is mixed in the paint 60. Instead of applying the paint 60, the metal oxide may be previously mixed into the raw material of the case 10 and the lining 49 in the same manner as in the above method (c).

れない。The present invention is not limited to the above embodiment, but can adopt various forms. The photocatalyst 41 should just be arrange | positioned at least the surface which the ultraviolet-ray from the ultraviolet lamp 50 of the evaporator 40 hits, ie, the surface of the upstream. Bacteria get on the evaporator 40 by the air flow in the air passage 10a, so that the possibility of the presence of the bacteria is higher on the upstream surface of the evaporator 40. Therefore, by performing sterilization by the photocatalyst 41 on this upstream surface, the sterilization efficiency can be increased. Also, regarding the photocatalyst 61,
It is only necessary that the case 10 and the lining 49 be disposed on at least the surface of the case 10 and the lining 49 where the ultraviolet rays from the ultraviolet lamp 50 strike. The photocatalyst for odor decomposition 34 and the photocatalysts for sterilization 41 and 61 may be different from each other as long as they cause desired catalytic action by the same light.
The light source is not limited to an ultraviolet light source such as the ultraviolet lamp 50 as long as it causes a corresponding photocatalyst to cause a catalytic action.

Bacteria on the surface of the evaporator can be sterilized, and furthermore, it is possible to prevent odorous substances generated by the metabolism of the bacteria from entering the passenger compartment and impairing comfort. In the second invention, by performing sterilization with a photocatalyst on the surface on the upstream side of the evaporator having a relatively large amount of bacteria,
Sterilization efficiency can be increased. In the third aspect of the invention, by arranging the light source between the evaporator and the deodorizing member, it is possible to cause both the photocatalyst for sterilizing the evaporator and the photocatalyst for deodorizing the deodorizing member to have a catalytic action. Therefore, it is not necessary to provide a light source separately for each photocatalyst, and the cost can be reduced. According to the fourth aspect of the invention, it is possible to sterilize bacteria that have advanced from the evaporator to the case, and it is possible to more reliably prevent the comfort in the vehicle compartment from being impaired. According to the fifth aspect of the present invention, it is possible to sterilize bacteria that have entered the lining from the evaporator, and it is possible to more reliably prevent the comfort in the vehicle compartment from being impaired.
