る。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a deodorizing element used in a refrigerator, an entrance storage (a shoe box), a toilet, a cooker and the like, and a deodorizing device using the deodorizing element.

気成分を活性炭の微細孔に物理吸着させて脱臭するもの
であった。2. Description of the Related Art As a conventional deodorizing element of this type, one using activated carbon is generally used. In the case of using this activated carbon, the deodorizing element is diffused or dispersed in the fine pores on the surface of the activated carbon molded in a honeycomb shape. The odor was brought into contact by circulating ventilation, and the odor component was physically adsorbed in the fine pores of the activated carbon to deodorize.

気を酸化マンガンで吸着脱臭するものもあった。Further, in the case of using ozone, an ozone deodorizing device is constituted by a high pressure generator, an ozonizer and an ozone decomposing catalyst, and odor components are decomposed by the oxidizing ability of ozone generated by the high pressure generator and the ozonizer. It was deodorized, and excess ozone was decomposed by an ozone decomposition catalyst. Then, after deodorizing with ozone, there is also a method in which the remaining odor is adsorbed and deodorized with manganese oxide.

【発明が解決しようとする課題】ところが、前記のよう
な脱臭素子及び脱臭装置においては、以下のような問題
があった。However, the above deodorizing element and deodorizing device have the following problems.

飽和となり脱臭効果がなくなり、交換する必要があっ
た。この脱臭効果がなくなったものを交換せずに長期間
おいておくと、臭気成分を吸着した活性炭が逆に臭気発
生源となってしまう場合があった。That is, in the case of using the adsorption action using activated carbon, since the odor component is adsorbed on the activated carbon to deodorize, the adsorption amount of the odor component adsorbed on the activated carbon increases as the use time elapses. However, the amount of newly adsorbed adsorbates decreased and the deodorizing effect decreased with the lapse of time, and finally the adsorption became saturated and the deodorizing effect disappeared, and it was necessary to replace it. If the deodorizing effect-depleted product is left for a long time without being replaced, the activated carbon having adsorbed the odorous component may become an odor generating source.
【０００７】また、オゾンにより脱臭を行う場合におい

コストが高くなりという問題があった。Further, in the case of deodorizing with ozone, a high pressure generator for generating ozone, an ozonizer, an ozone decomposing catalyst, etc. are required, and there is a problem that the structure is complicated and the cost is high.
【０００８】そして、常温分解触媒においても、常温で

臭効果が低下する。Also in the room temperature decomposition catalyst, the decomposition rate at room temperature is extremely slow, and most of the deodorizing effect is due to adsorption, and the deodorizing effect is reduced as in the case of using activated carbon.
【０００９】このような吸着方式の脱臭においては、い
ずれの場合も吸湿しやすく、湿度が高い雰囲気では極端
にその脱臭性能が低下する。In any of the adsorption type deodorizing methods, the deodorizing performance is extremely lowered in an atmosphere having a high humidity because moisture is easily absorbed.
