Description

TECHNICAL FIELD The present invention relates to an air conditioner, an air conditioner, an air purifier, a warm air blower,
The present invention relates to deodorization of air from electric devices such as a blower, an air circulator, and a dehumidifier.

Conventional technology Conventionally, air conditioners, air conditioners, air purifiers, warm air blowers, air blowers, air circulators, dehumidifiers, etc. perform their respective functions, but lack air cleaning functions, and remove dust and dirt with filters. Was the main. Even if there is a deodorizing function such as an activated carbon filter, the effect is temporary and none is durable.

Further, in the above-mentioned equipment, there is a problem that the heat collecting fins and the heat radiating fins having a very complicated shape are condensed, and the bacteria propagate there to generate an unpleasant odor.

Further, since such a fin has a complicated shape and cannot be cleaned, the odor from here has been an extremely serious problem.

SUMMARY OF THE INVENTION Therefore, the first object of the present invention is to form a novel catalyst film that catalytically eliminates such odors by a simple method.

A second object is to provide a method capable of easily forming an odor eliminating surface on the surface of the heat collecting fin, the heat radiating fin and the like having the above-mentioned complicated shapes.

Means for Solving the Problems In the invention for achieving the first object, a deodorizing surface is constituted by a metalloporphyrin derivative film formed on a substrate by electrolytic polymerization or an adsorption method.

Further, the invention for achieving the second object is to form a metal porphyrin derivative film by immersing it in a bath for electrolytic polymerization or adsorption reaction using a heat exchange unit having a large number of metal heat collecting or radiating fins as a substrate. It is a method of forming a deodorant surface by doing.

Action The deodorant surface of the present invention comprises a novel deodorant film made of a metalloporphyrin derivative having a room temperature catalytic action. This film is a film that can be easily formed by electrolytic polymerization or adsorption method.In the case of electrolytic polymerization, it is an extremely thin deodorant functional film when a voltage is applied by immersing a substrate having a conductive surface in an electrolytic polymerization reaction bath as an electrode. Can be easily formed. On the other hand, in the adsorption method, a film can be formed only by immersing it in a reaction bath.

Since this film is extremely thin, there is also a feature that the heat transfer efficiency on the surface of the heat collecting and radiating fins is hardly impaired. Since this film has a catalytic action and an antibacterial action, it is difficult for contaminants to adhere to the surface thereof, and rather the heat transfer efficiency can be kept high in long-term use.

The generation of odors on the fins is mainly due to the condensation of bacteria (mold, etc.). A substance having a bactericidal action may cause an unexpected harmful effect, but the above-mentioned antibacterial action is to prevent bacterial growth and not to sterilize. Therefore, it is suitable for cleaning the air also from this point.

Examples As the metal porphyrin derivative having a deodorizing effect used in the present invention, a phthalocyanine derivative is suitable, among which Fe, Ni,
The metal phthalocyanine complex of Co, Mn, Cu is the best.

Methods of electrolytic polymerization include solution electrolytic polymerization and micelle electrolytic polymerization used in the case of insoluble monomers. In the micelle electropolymerization, a micelle forming agent having a redox group is electrolyzed and polymerized, and at that time, metal porphyrin in the micelle is incorporated into the polymer. Further, in the adsorption method, the deodorant film of the present invention can be formed only by immersing it in a porphyrin derivative solution reactive with the substrate.

The surface for deodorization comprising the metalloporphyrin derivative film of the present invention is a metal heat collector having a very complicated shape such as an air conditioner, an air conditioner, an air purifier, a warm air blower, an air circulator, and a dehumidifier. Alternatively, it is characterized in that it is easily formed by electrolytic polymerization on the radiation fin. This deodorant film forms a metal porphyrin derivative film only by immersing a heat exchange unit having a large number of metal heat collecting or radiating fins in a bath for electrolytic polymerization or adsorption reaction.

Embodiments of the present invention will be described below with reference to the accompanying drawings.

Example 1 A Co phthalocyanine polymer film obtained by electrolytically polymerizing octaethyl Co phthalocyanine as a monomer on an Al electrode was taken out. This was put in a container, hydrogen sulfide gas was introduced, and its deodorizing effect was measured, and it showed a great effect. Further, when the plate on which the deodorizing film was formed and the general Al plate were left in the air in a state of being condensed at 30 ° C., mold was not generated on the deodorizing film after one month, but Mold and odor were generated on the Al plate.

Example 2 A Fe phthalocyanine-containing polymer film obtained by electrolytically polymerizing Fe phthalocyanine with a cationic surfactant having a redox group to form a suspension reaction solution was taken out.
This was placed in a container, hydrogen sulfide gas was introduced, and the deodorizing effect was measured. As a result, a large effect was exhibited as in Example 1.

Example 3 A substrate having an amino-modified surface was immersed in an aqueous solution of Co phthalocyanine tetrasulfonic acid and adsorbed to obtain a Co phthalocyanine derivative film. This was put in a separate container, and hydrogen sulfide gas and ammonia gas were introduced, and the deodorizing effect was measured. As a result, a large effect was shown for all the gases. However, ammonia was not catalytic and was deodorized by adsorption. Further, when the plate having the deodorant film formed thereon and a general Al plate were left in the air in a dew-condensed state at 30 ° C., mold did not occur on the deodorant film even after one month.

Example 4 A heat exchange unit having a large number of metal heat collecting or radiating fins for an air conditioner was immersed in the same electrolytic polymerization reaction bath as in Example 1 and similarly electrolytically polymerized. After dedoping by applying a reverse potential, the air conditioner was taken out and assembled. After using this air conditioner for 2 hours every day for 1 month, when the odor at the time of starting was measured, it was about 1 / compared to the one without the deodorant film.
It showed an odor concentration of 40.

EFFECTS OF THE INVENTION As described above, the present invention forms a deodorizing surface composed of a metalloporphyrin derivative film on a substrate by electrolytic polymerization or an adsorption method. A deodorant surface can be very easily formed on the replacement unit. In addition, the thin film of the present invention,
Since it is a dense thin film of 1 μm or less, it has a high-performance deodorizing function. By applying this to a heat exchange unit, a deodorant thin film can be easily formed even in a narrow space between fins of complicated shape, and since it is an extremely thin thin film, the fluid passing through the heat exchanger Since the resistance does not increase and the heat conductivity of the fins hardly decreases, the deodorizing function can be added without lowering the performance of the heat exchanger. In addition, an excellent deodorant member can be obtained by a novel manufacturing method applying the electrolytic polymerization method.

That is, a combination of the specified material, forming method, and applied equipment can provide an unexpected and excellent effect.
