触媒２は１セットとして構成される。[0003] The photocatalyst section 2 is formed in a honeycomb shape so as to increase the surface area as shown in the sectional view of Fig. 2A-A. This surface is coated with a photocatalyst containing titanium oxide as a main component. The light source 1 is installed at a certain distance to uniformly illuminate the inner surface of the photocatalyst 2. By irradiating the photocatalyst portion with light, the catalyst is reacted to decompose and deodorize odors such as ammonia odor contained in the air passing through the honeycomb portion. Therefore, the light source 1 and the photocatalyst 2 are always configured as one set.

高くなる。FIG. 3 shows a state in which the light deodorizing filter shown in FIG. 1 is incorporated in an air conditioner. The light deodorizing filter is installed at a suction port of the air conditioner 3. In this case the light deodorization filter because of the need to apply the photocatalyst 2 light efficiently thickness h 1 is thick and the light source of the light of the photocatalyst 2, it is necessary to take the distance h 2 between the photocatalyst 2 and the light source 1. For this reason, the height of the product is increased when configuring the light deodorizing device, and the device cannot be directly attached to the air conditioner 3. For this reason, it is necessary to install a filter box 4 for mounting, and install a light deodorizing device therein, and the height of the product is increased by the amount of the filter box.

ず触媒反応が低下するため効率が落ちる。Since the effect of the photocatalyst increases as the area of contact with the circulating air increases, it is necessary to increase the area of the photocatalyst. Therefore, in the known examples have taken larger photocatalytic portion shaped to contact the circulating air is formed in a honeycomb shape as shown in FIG. 2 and the height h 1 is also 40 to 50 mm. The light emitted from the light source 1 is radiated from the light source 1. The emitted light from the light source 1 is transmitted radially around the light source, so that the light hits the upper part ((a)) of the honeycomb at the end of the photocatalyst 2 (b). It is irradiated only to the upper surface from the part ()). For this reason, the lower part (c) does not directly reach the light source and the catalytic reaction is reduced, so that the efficiency is reduced.

光脱臭フィルタを提供することを目的とする。[0006] This phenomenon increases from right below the light source to the end, and the overall efficiency of the entire light deodorizing filter decreases.
In order to solve this problem, the first invention aims at irradiating light from the inner surface using glass fiber to cause a catalytic reaction over the entire area of the fiber, and at the same time, irradiating light from inside so that a shadow cannot be formed. It is an object of the present invention to provide a highly efficient light deodorizing filter.

形も自由にできる特性をもつ。According to the first aspect of the present invention, the use of the optical fiber has a characteristic that the light from the light source can be uniformly irradiated from the inner surface of the fiber. By coating this surface with a photocatalyst, it is possible to cause a catalytic reaction in the entire optical fiber, and it is possible to have a very efficient photodeodorizing function. In addition, since the light passes through the inside of the optical fiber, the shape of the optical fiber is not shadowed and the shape can be freely shaped as compared with the irradiation of light from the outside.

要がなくなる。According to the second aspect of the present invention, the light can be sent to the entire optical fiber by collecting the end of the optical fiber at the light source. Therefore, it is not necessary to arrange the light source and the photocatalyst at a distance in order to irradiate the entire area with the light from the light source as in the known example.

In addition, since there is no need to modify a light source that requires electricity, safety is improved.

射板１３が取付けられている。FIG. 4 to FIG. 6 show an embodiment of the present invention. FIG. 4 shows the structure of the light deodorizing filter of the present invention. Photocatalyst coating The optical fiber 9 has a surface coated with a photocatalyst containing titanium oxide as a main component. The coating thickness is set to about 1 to 5 μm so that internal light can be radiated to the outside to some extent. The optical fiber light-receiving part 10 is configured to project from one end face of the filter frame 8. The light source 11 is arranged so that light strikes the optical fiber light receiving unit 10. The light source frame 12 is formed in a semicircle so as to surround the light source 11 so that the light from the light source 11 does not leak to the outside, and to concentrate the reflected light from the light source 11 on the optical fiber light receiving unit 10. A light source reflector 13 is attached to the semicircular inner surface to increase the efficiency of reflected light.

臭作用が行われる。In operation, when the light source 11 is turned on, light is collected at the optical fiber light receiving section 10, and transmitted from the end to the entire area of the photocatalyst coated optical fiber 9, and the catalytic reaction is performed in the entire area. At this time, the odor contained in the air passing through the inside of the filter frame 8 reacts with the photocatalyst coating portion to perform a deodorizing action.

安価でコンパクトな取付が可能となる。Advantageously, (1) light can be guided to the entire surface of the optical fiber, so that the reaction with the photocatalyst can be performed on the entire outer surface. For this reason, a highly efficient one can be obtained. (2) Since the outer surface area can be increased by forming the optical fiber in a permanent shape, the deodorizing filter can be made compact. (3) It is sufficient to irradiate light from the end face by making use of the characteristics of the optical fiber, so that the light source can be installed at the end of the filter. Therefore, the thickness of the filter can be kept low, and a thin filter can be manufactured. FIG. 6 shows a state where the filter is attached to the air conditioner main body. However, since the thickness can be reduced, the deodorizing filter 14 can be attached to the suction port of the air conditioner, and the filter box 4 becomes unnecessary as in the known example shown in FIG.
Inexpensive and compact mounting becomes possible.

製作可能となる。(First Invention) Since the photocatalytic reaction can be uniformly caused on the entire surface of the photocatalyst-coated optical fiber 9, high efficiency performance can be obtained. In addition, since there is no need to irradiate light from the outside as in the prior art, there is no portion that becomes a shadow, and a more efficient product can be obtained. Therefore, a compact and inexpensive product can be manufactured.

Therefore, it is not necessary to keep the distance between the light source and the photocatalyst part unlike the known example, so that the fiber can be made compact. By changing the number of coated optical fibers, filters having different deodorizing capacities can be easily configured.
