とする。Furthermore, in this embodiment, the bright spot 1 of the ultraviolet lamp ] 3
', 3a is a position as close as possible to the lower end of the aluminum reflector 14 and the adsorbent 12, but at a distance that does not cause contact due to vibration during transportation (dimension A, 8 in Figure 2). The absorbent 2 is positioned so that the intensity of the ultraviolet rays irradiated is the strongest in the area where the concentration of odor components adsorbed is high. In other words, it is effective to set the bright spot ]-38 of the photocatalytic excitation light source near the position where the adsorption distribution of the adsorbent 12 is the highest.For example, the lighting time (irradiation time) of the light source is set to 20 minutes. ~40 minutes,
The distance between the bright spot 1-38 and the adsorbent 12 is about 1°5 to 5 marks.
また、紫外線の強度と臭気成分の分解能力とはほぼ比例
的な相関性があるとともに、紫外線の強度も距離の２乗
に反比例する関係にあることは周知である。Furthermore, it is well known that the intensity of ultraviolet rays and the ability to decompose odor components have a substantially proportional correlation, and that the intensity of ultraviolet rays also has a relationship that is inversely proportional to the square of the distance.

ることができる。In this example, by employing the deodorizing device shown in FIG. 2 in the refrigerator shown in FIG. Odor components adsorbed on the adsorbent are decomposed by the lamp and the photocatalyst layer, and the honeycomb-shaped activated carbon is cleaned, so that the deodorizing effect can be maintained for a long period of time.

る。Further, by locating the bright spot of the ultraviolet lamp near the position where the concentration of the odor component of the adsorbent is high, that is, the position where the adsorption distribution is the thickest, it is possible to efficiently oxidize and decompose the odor component. The irradiation time of the UV lamp to decompose these odor components is almost the same as the defrosting time of a refrigerator, so there is no need to use a dedicated timer in the UV lamp lighting circuit of the deodorizing device. Appropriate irradiation can be achieved by synchronizing (parallel connection).
