Description of the Related Art As a conventional deodorizing method for equipment having heat exchange fins such as air conditioners and refrigerators, it has been common to use activated carbon for a long time. This is for adsorbing odorous components in a refrigerator by diffusion or circulating air into fine pores on the surface of activated carbon formed into pellets, granules or honeycombs.

分解脱臭触媒で分解するものである。Recently, there is also one using ozone. In this method, a part of odor is decomposed by the oxidizing ability of ozone, the remaining odor is adsorbed by an ozone decomposing deodorizing catalyst containing manganese oxide as a main component, and excess ozone is decomposed by the ozone decomposing deodorizing catalyst.

成分を酸化分解して吸着性能を再生するものである。In addition to deodorization, which is mainly due to the above-mentioned adsorption action, those which are regenerated by electric heating have been proposed and commercialized. In this method, an adsorbent and a noble metal-based oxidation catalyst are carried on the surface of the resistance heating element, and usually the adsorption deodorization is performed at room temperature, and when the adsorption performance is lowered, the resistance heating element is energized.
When heated to 00 ° C. or higher, the odorous components adsorbed on the surface are oxidized and decomposed to regenerate the adsorption performance.

【発明が解決しようとする課題】ところが、上記した脱
臭器のうち吸着作用を用いたものでは、以下のような問
題点がある。すなわち、活性炭を用いたものでは吸着量
が次第に増していって脱臭効果が低下してきてついには
吸着飽和となり脱臭効果がなくなり、場合によっては逆

気濃度が高い場合にはオゾン分解脱臭触媒に次第に臭気
が吸着していき、活性炭と同様に脱臭効果が低下してい
る。さらに、脱臭効果がなくなった時点で脱臭剤を交換
する必要がある。However, the above-mentioned deodorizer using the adsorption function has the following problems. That is, in the case of using activated carbon, the amount of adsorption gradually increases and the deodorizing effect decreases, and finally the adsorption becomes saturated and the deodorizing effect disappears, and in some cases, it becomes a source of odor generation. Even in the case of ozone, when the odor concentration is high, the odor is gradually adsorbed to the ozone decomposing deodorizing catalyst, and the deodorizing effect is lowered like activated carbon. Further, it is necessary to replace the deodorant when the deodorizing effect is lost.

ストの高いものとなってしまう。Further, in a form such as an air conditioner or a refrigerator installed in an actual product, the space velocity (SV value) is too large, so that a sufficient contact time between the odorous gas and the deodorant cannot be obtained, and one-pass The odor removal rate is low and sufficient deodorizing performance is not obtained. It is sufficient to reduce the space velocity to improve the deodorizing performance, but for that purpose, it is necessary to mold a large honeycomb with the adsorbent itself or an appropriate carrier, which results in high cost.

法においては脱臭剤を交換する必要がないが、加熱再生

り、安全面においても危険性が高い。Further, in the deodorizing method using heat regeneration by energization, it is not necessary to replace the deodorant, but it is necessary to raise the temperature of the deodorizing element to about 300 ° C. or more for the heat regeneration. Will rise unnecessarily, and there is a high risk in terms of safety.

が点灯している間でないと脱臭効果はない。Also, in the one disclosed in JP-A-62-255741, since the contact area is small, a sufficient contact time between the odorous gas and the photocatalyst layer cannot be obtained, and the one-pass odor removal rate is low and sufficient. Deodorizing performance cannot be obtained. Furthermore, since the photocatalyst itself does not have a good odor adsorption property, the deodorizing effect cannot be obtained unless the germicidal lamp is turned on.

The deodorizing coat 10 is formed by applying a room temperature oxidation catalyst 10a and an adsorbent 10b using a binder 10c.

して、再生される。At this time, if ultraviolet rays are irradiated, titanium oxide, which is a photocatalyst, is excited, so that the odorous components are oxidatively decomposed at room temperature to become odorless and desorbed, and then go out from the outlet 6. Even if not irradiated with ultraviolet rays, the odorous components continue to be retained in the adsorbent, and when the amount of adsorption is saturated, the ultraviolet rays are irradiated to oxidize and decompose the adsorbed odorous components to be regenerated.

This is the case. In this case, titanium oxide is excited by ultraviolet rays having a wavelength of 400 (nm) or less contained in a fluorescent lamp and natural light, and the odorous components are similarly oxidized and decomposed at room temperature.

なるという大きな欠点がある。In particular, Cu-ZSM5 showed excellent adsorption performance. Titanium oxide, which is a room temperature oxidation catalyst, also showed moderate adsorption performance for this study gas, but it hardly adsorbs sulfur compound-based gases such as dimethyl sulfide, and neutral gas such as acetaldehyde. Is inferior in adsorption performance. Further, manganese oxide and copper oxide, which have been conventionally applied as room temperature catalysts, are also difficult to adsorb to dimethyl sulfide and acetaldehyde, and there is a big drawback that water is poisoned.

る。Since the heat exchanger with a deodorizing function of the present invention has the above-mentioned constitution, the invention according to claim 1 applies the deodorizing coat to the heat exchanging fins having a large contact area.
The one-pass removal rate of odor is increased, and a deodorization rate that has never been obtained can be obtained. Further, since the odorous component adsorbed by the action of the room temperature oxidation catalyst is decomposed in the room temperature range, it becomes maintenance-free. Furthermore, since the heat exchanger is applied as a carrier, a separate carrier is not required, and the cost can be reduced.

Furthermore, since it is only necessary to regenerate at the time when the adsorption is saturated, the frequency of regeneration is reduced and energy saving can be realized.

Since ZSM5 ion-exchanged is used as the adsorbent, it is difficult to absorb moisture, and most odorous components can be adsorbed, and the deodorizing performance is improved.

Further, the invention according to claim 6 is provided with a light that emits ultraviolet rays, so that the oxidizing ability is improved and the tar can be decomposed in the tobacco. In addition, the bactericidal action is increased and the generation of mold in the heat exchanger can be suppressed.
