観点から脱臭機能の高度化が図られている。2. Description of the Related Art In recent years, there has been an increasing need for improving the comfort of living spaces. In particular, in order to improve the quality of air quality in the living environment, household appliances also have air conditioners,
The deodorizing performance of the air purifier is improved and the deodorizing function is added to the vacuum cleaner. In addition, even in refrigerators, which are electric appliances that are the main part of eating habits, the deodorizing function has been enhanced from the viewpoint of suppressing the transfer of odors because the environment inside the refrigerator has become highly humid and can be stored without wrapping.

に関するニーズが高まってくると予想される。[0003] On the other hand, in the fields where deodorization needs will increase in the future, there are medical care and welfare facilities such as elderly care facilities and hospitals. In particular, in elderly facilities and home care homes, it has become a problem that the indoor air quality deteriorates due to the effect of offensive odors that occur when changing diapers and using portable toilets for bedridden elderly people. In the situation where the elderly population is increasing, it is expected that the need for this odor control will increase.

する脱臭技術が必要となる。The problem of odor in the living room of the elderly who need nursing care, especially the bedridden elderly, is often caused by excrement such as stool and urine. The stool odor diffuses into the room all at once when the diaper excreted by stool is replaced and when stool is excreted by a portable toilet. Odor gas derived from stool is mainly composed of sulfur-based gas, and since hydrogen sulfide has a particularly large influence, a deodorization technique for removing hydrogen sulfide diffused indoors in a short time is required.

る脱臭技術が必要となる。On the other hand, the urine odor is often attached to clothes and bedding of the elderly, and in elderly people with dementia, urine is often discharged to the floor, resulting in the odor of urine remaining in the room. Among the main odorous gases derived from urine, ammonia, which is an irritating odor, has a particularly large influence and stays indoors at all times. Therefore, a deodorizing technology for continuously reducing the concentration of this ammonia is required.

した材料も市販されている。Activated carbon is well known as a conventional deodorizing device, and the van der Waals force acting on the pores of the surface physically adsorbs odorous substances to purify air. Furthermore, recently, a material in which a photocatalyst is supported on the surface of the activated carbon is commercially available.

脱臭装置を説明する。Further, as a deodorizing device using activated carbon carrying a photocatalyst, there is one disclosed in Japanese Patent No. 2574840. The conventional deodorizing device will be described below with reference to the drawings.

１の通風面近傍に設置された構成である。In FIG. 7, reference numeral 21 denotes a deodorizing element body, which has a honeycomb shape in order to increase the contact area with air. The deodorizing element body 21 forms a honeycomb using activated carbon 23 as a constituent material, and a surface state as shown in FIG. 8 is formed by attaching a photocatalyst 24 to the surface of the activated carbon 23. Further, reference numeral 22 is an ultraviolet lamp for activating the photocatalyst 24, and the deodorizing element main body 2
It is a configuration installed near the ventilation surface of No. 1.

とになる。With the above structure, when the air containing odor is passed through the deodorizing element body 21, the odor component is adsorbed by the adsorption action of the activated carbon 23 having a porous surface. Further, by irradiating the ultraviolet lamp 22 to excite the photocatalyst 24, the odor near the photocatalyst 24 is oxidatively decomposed, so that the odorous substance on the activated carbon 23 diffuses toward the photocatalyst 24, and finally, the activated carbon is activated. All the odorous substances on 23 are decomposed by the photocatalyst 24, and the adsorption performance of the activated carbon 23 is restored.

する。The present invention solves the conventional problems, and an object of the present invention is to provide a deodorizing device which improves the removal performance of ammonia and hydrogen sulfide, and a deodorizing apparatus using the same.

イトが減少することでアンモニアや硫化水素の吸着性能

下するという欠点があった。Further, in the above conventional structure, when used in a high humidity atmosphere, the activated carbon 23 adsorbs water and the number of adsorbing sites is reduced, so that the adsorption performance of ammonia and hydrogen sulfide is lowered, and in particular, it is insoluble in water. However, there is a drawback that the performance of hydrogen sulfide is significantly reduced.

あった。Further, in the above-mentioned conventional structure, since the surface of the black activated carbon 23 carries the photocatalyst, the ultraviolet rays absorbed by the activated carbon 23 even when the surface of the deodorizing element body 21 is irradiated with the ultraviolet rays by the ultraviolet lamp 22. However, since the photocatalyst 24 cannot be excited efficiently, the decomposition of ammonia and hydrogen sulfide adsorbed on the activated carbon 23 is slow.
