Description

  The present invention relates to a deodorizing method and a deodorizing apparatus for decomposing or reducing odor molecules and smoke in a relatively narrow space such as in an automobile, and a gaming machine such as a pachinko machine or a slot machine. It is related to a deodorizer or an air purifier that is installed near the door to eliminate odor and keep the indoor environment healthy.

  In the conventional technology, since there are a wide variety of odors, it has been difficult to eliminate the odor in the car. Similarly, cigarette smoke and odors often did not disappear with ozone. It was found that it disappeared when passing between the electrodes of the ion generator. Further, it has been found that the odor of ammonia is not deodorized only by passing through the ion generator, but is easily erased by ozone.

Although it has been known for a long time that ozone has a strong deodorizing effect, it has been applied to various fields, but it is also known that ozone has a relatively strong toxicity. Therefore, for this purpose, it has been devised to avoid the generation of ozone as much as possible.
Japanese Patent No. 3621372

  There are many methods for deodorizing, and many devices have been developed and commercialized. As described above, there are a wide variety of deodorizing methods, and activated carbon, charcoal, bamboo charcoal, chemicals, fragrances, titanium oxide, microorganisms, ceramics, ozone, and the like are used, but there is no firm method. The problem to be solved by the present invention is to provide a device for deodorizing and deodorizing by reducing the generation of ozone as much as possible, greatly reducing the odor molecules in the air using bamboo fiber, and is simple in structure. It is to provide a miniaturized sterilization / sterilization apparatus.

  The bamboo fiber described here was produced by the method described in the patent document (Japanese Patent No. 3621372), and the right to use the explosive bamboo fiber has been approved by the maintainer of this patent right.

  The conventional ozone deodorization device is configured to introduce odor molecules into the device and react with ozone by operating the ozone generator and the blower at the same time. There was a problem that a sufficient deodorizing effect could not be obtained because it was not possible to remove the odor molecules adsorbed on the wall surface of the room.

  In addition, there are other deodorizing methods such as bamboo charcoal and bincho charcoal, which are adsorbents of odorous molecules, and a method of preventing bad odors by using a single fragrance or mixing two or more fragrances. is there. Due to the limited effectiveness of the adsorbent, bamboo charcoal and bincho charcoal had to be changed regularly, such as once every few months. In addition, there are solid and liquid deodorants that use fragrances, etc., but due to their volatility, they gradually decreased and had to be added with fragrances.

  In addition, as a problem in use, in hotels and ryokan, the perfume of guests in guest rooms with tatami mats and carpets, the smell of incense burned in the guest rooms, and the body odor of humans, etc., are stained by the walls. It was often in a state of being. In the above conventional deodorizer, it took several days to remove the odor in such a case, and during that time, there was a problem that the guest room could not be provided to the next customer.

  The same problem occurs in hospital rooms and elderly care facility rooms, and the unique odor generated by patients and elderly people inside the facility is adsorbed on the wall surface. Therefore, an effective deodorizing device is desired. It was.

  The present invention has been made to solve the above problems, and is expected to provide a deodorizing method and a deodorizing apparatus capable of effectively removing odors in a space such as a cabin. It has been developed as a cause.

  In the present invention, even if it is 100V (volt) AC current used at home or a battery such as an automobile, it is DC current and can be used even with a voltage of 12V or 24V. There is a need for a relatively lightweight deodorizing method and deodorizing device that is devised so that it can be controlled with a small electronic board so that it can be replaced very easily.

  An object of the present invention is to provide a deodorizing device, which is achieved by a device in which a plasma discharger that causes a large voltage difference and a blown bamboo fiber adsorbed with titanium oxide are introduced as a filter.

  In the above apparatus, the crushed bamboo fiber adsorbs titanium oxide as a decomposition photocatalyst of organic matter. This is because this explosive bamboo fiber tends to adsorb organic substances, which are odor molecules, like activated carbon.

  Substances such as activated carbon, when the odor molecules adsorbed on the surface are saturated, their effectiveness is greatly reduced, but by adsorbing titanium oxide, the odor molecules adsorbed on bamboo fibers are decomposed. The deodorizing effect can be maintained for a very long time.

  In the case of plasma discharge, the deodorizing effect greatly depends on the shape and distance of the high voltage side electrode and the ground side electrode. The present invention has found that the high voltage side electrode is a needle-like conductive material that is as thin as possible, and that the flow of the electron wind becomes stronger when the earth side electrode has a hemispherical shape.

  The metal stainless steel has the feature that the odor disappears by rubbing the odor on the hand. Here, by applying this property, and using it as an electrode on the earth side, the smoke and odor of cigarettes were instantaneously decomposed by a strong electrical stimulus received from the high voltage side.

  The present invention has been made to solve the above-mentioned problems. The odor of public closed spaces where many people get on and off such as taxis and pachinko parlors are used in pachinko parlors. It aims at providing the deodorizing method and deodorizing apparatus which can arrange | position adjacently and can remove the smoke and odor of tobacco effectively.

  The deodorizing apparatus manufactured according to the present invention was installed in a taxi where the body odor and tobacco odor were stained. All the taxi doors were closed and sealed in the experiment. The power cord was plugged into the cigarette terminal, and the device was turned on and started. As a result of operating this apparatus in a closed taxi for 20 minutes, the odor almost disappeared.

In order to confirm this fact, the ammonia gas was filled in a sealed room (in the taxi car) of about 3.5 m ³ , and its concentration was measured to be about 5 ppm. After 30 minutes, the ammonia concentration in the vehicle was again measured and found to be about 0.3 ppm.

As shown in FIG. 2, the deodorizing apparatus manufactured according to the present invention was installed in a sealed room of 8 m ³ , and ammonia was put into the room, and the degree of reduction was examined. The deodorizer was turned on and sealed for 20 minutes. As a result, there was a strong irritating odor before operating the apparatus, but the odor almost disappeared after 20 minutes.

In order to confirm this fact, a room having an area of about 8 m ³ was filled with an ammonia concentration of about 5 ppm, and after 30 minutes, the concentration was measured with a detector tube and found to be 0.2 ppm.

  The present invention is an effective technique for erasing cigarette smoke and odors, from a small deodorizer that can be used at home to a large device that must be deodorized on the environment such as an animal house. Can be applied.

The figure shows a schematic view of the air purifier of the present invention.
