Description of the Related Art Various harmful components called odors are generated from various sources, for example, daily living environment, various facilities such as factories, human waste treatment plants, garbage disposal plants, and become a problem as "odor odor pollution". I have. Examples of the odor-causing substances include ammonia, nitrogen-containing compounds such as amines (trimethylamine, triethylamine, etc.), sulfur-containing compounds such as hydrogen sulfide, mercaptans (methyl mercaptan, etc.), aldehydes (formaldehyde, acetaldehyde, etc.),
Many compounds such as lower fatty acids (formic acid, acetic acid, valeric acid, etc.) are included.

る。[0003] Conventionally, activated carbon has been widely used for the deodorizing treatment of malodorous components. However, activated carbon alone has a small adsorption capacity for nitrogen-containing compounds such as ammonia and sulfur-containing compounds such as hydrogen sulfide, and adsorbents supporting halogen compounds, metal ions, acids, alkalis, and the like have been proposed.

衡吸着濃度の増加が発生し、課題となっている。[0004] However, it has not yet achieved a sufficient deodorizing ability. Further, although zeolite, silica gel, activated alumina and the like are also used as deodorizers, their adsorbing capacity is small and the equilibrium adsorption concentration, which is an index of the deodorizing ability, increases with the increase in the amount of adsorption.

る。Further, a photocatalyst such as titanium oxide oxidizes and decomposes odor components adsorbed on the surface of titanium oxide by irradiation with light such as ultraviolet rays, so that it has a sufficient reaction surface and has an equilibrium adsorption concentration as long as irradiation with light is performed. There is no such thing, but there is a problem that the effect on deodorization cannot be expected when light irradiation is not performed. In order to compensate for these disadvantages, Japanese Patent Publication No. 6-102155 discloses a deodorant obtained by sintering a mixture of an adsorbent and a photocatalyst.

が起きにくくなるといった課題が存在していた。However, in the conventional deodorant, since the adsorbent and the photocatalyst are mixed on the same substrate, the density of the surface of the titanium oxide as the photocatalyst material is reduced, and the decomposition efficiency by the photocatalyst is reduced. There is a problem that a decrease occurs. Furthermore, since the decomposition reaction of the adsorbed substance by light irradiation occurs only on the titanium oxide surface, the adsorbed substance to be decomposed must move two-dimensionally or three-dimensionally from the adsorbent surface to the titanium oxide surface. If the adsorbent has strong holding power for the adsorbed substance,
There has been a problem that the diffusion process of the adsorbed substance is rate-determining and an effective decomposition reaction is unlikely to occur.
【０００７】このように従来の脱臭剤においては光触媒

に保持する事が困難であった。As described above, since the effect of the photocatalyst cannot be sufficiently utilized in the conventional deodorizing agent, the effect as the deodorizing agent is reduced, and it has been difficult to maintain a good deodorizing effect over a long period of time. .

A deodorizing apparatus for efficiently decomposing a photocatalyst, shortening the irradiation time and maintaining a good deodorizing effect over a long period, and a refrigeration cycle using the same. It is intended to provide a device.
【００１０】[0010]
【課題を解決するための手段】この目的を達成するた
め、本発明は以下のような構成とする。In order to achieve this object, the present invention has the following arrangement.
【００１１】本発明の請求項１に係わる脱臭装置は臭気

造体を通過する空気の流れより見て前記構造体の背面側
に加熱部を有し、さらにその後部に光触媒材料からなる
薄膜面に光を照射する光源と光触媒材料からなる薄膜が
形成された構造体を設けた構造となっていることを特徴
としたものである。According to a first aspect of the present invention, there is provided a deodorizing apparatus comprising: a structure on which an adsorbing substance for adsorbing odorous substances is carried; and a heating unit provided on a back side of the structure as viewed from a flow of air passing through the structure. And a light source for irradiating the thin film made of the photocatalytic material with light and a structure on which a thin film made of the photocatalytic material is formed.
【００１２】これにより、吸着作用による臭気物質の吸

することが可能となる。Thus, the adsorption of the odorous substance by the adsorption action and the decomposition reaction of the odorous substance on the surface of the thin film made of the photocatalytic material are decomposed, and a certain amount of the adsorbed substance that is desorbed by being heated by the heating unit is decomposed. Odorous substances can be efficiently decomposed and removed. Further, since the odorous substance adsorbed by the adsorbing substance is reduced at regular intervals, the deodorizing effect can be favorably maintained over a long period of time.
【００１３】また本発明の請求項２に係わる脱臭装置

リカ，アルミナ，活性炭のうち少なくとも１種類を含む
ものであることを特徴とした請求項１に記載の脱臭装置
である。The deodorizing apparatus according to claim 2 of the present invention is characterized in that the adsorbing substance for adsorbing the odorous substance contains at least one of zeolite, silica, alumina and activated carbon. It is a deodorizing device.
【００１４】これにより、光照射が行われずに光触媒材

反応による臭気物質の捕集（固定化）を行っていないた
めに加熱部によって暖められた際に、吸着した臭気物質
を容易に脱離させることが可能である。Thus, even when no light irradiation is performed and no decomposition reaction occurs due to the photocatalytic material, it is possible to temporarily suppress various kinds of odorous substances at a low concentration below the olfactory threshold and not to make them feel odorous. . Furthermore, since the odorant is not collected (fixed) by a chemical reaction, the adsorbed odorant can be easily desorbed when heated by the heating unit.
【００１５】また、本発明の請求項３に係わる脱臭装置
は前記吸着物質が担持された構造体がハニカム形状であ
ることを特徴とした請求項１に記載の脱臭装置である。Further, the deodorizing apparatus according to claim 3 of the present invention is the deodorizing apparatus according to claim 1, wherein the structure carrying the adsorbed substance is in a honeycomb shape.
【００１６】これにより、臭気物質を含む空気と吸着物

製造過程が非常に簡便となる。さらには空気の流れに対
する垂直面が、均一で空隙の多い面となっているため
に、空気が通過する際に発生する通気抵抗を低く抑える
ことが可能となる。[0016] This makes it possible to arbitrarily change the contact area between the air containing the odorous substance and the adsorbent by changing the size and shape of the honeycomb, and furthermore, when the adsorbent is carried by dip coating. It is possible to uniformly support each surface of the structure,
The manufacturing process becomes very simple. Furthermore, since the plane perpendicular to the flow of air is uniform and has many air gaps, it is possible to suppress the airflow resistance generated when air passes.

Regardless, even when the photocatalytic decomposition reaction does not occur without light irradiation, it is possible to temporarily suppress many kinds of odorous substances at a low concentration below the olfactory threshold and not to make them feel as odor, Since the odorous substances are not collected (fixed), they are easily desorbed when heated by the heating unit, and at the same time, efficiently decompose by the photocatalyst for a long time. It is possible to provide a refrigeration apparatus that maintains a good deodorizing effect.
