Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a deodorizing method and a deodorizing apparatus. Specifically, the present invention relates to a deodorizing method and a deodorizing apparatus for performing sterilization and deodorization by a photocatalytic activity by titanium oxide and a deodorizing effect by a deodorizing agent.
[0002]
[Prior art]
Traditionally, indoor deodorization has been done by natural vaporization of fragrances and deodorizers, but it is constantly generated in environments where there is a strong chemical odor and urine odor, such as in a hospital room, or in a large number of workplaces. In an environment with a cigarette odor, deodorization by natural vaporization of the above fragrances and deodorizers has little effect.
[0003]
Therefore, these buildings have many closed-type structures, so air replacement by forced ventilation, sterilization and deodorization by ozone generators in hospitals, or indoor air is sucked by an electric fan and sterilized by a filter or sterilization lamp. There is a forced circulation type that blows air while deodorizing.
[0004]
Furthermore, in recent years, titanium oxide has a sterilizing and deodorizing effect as a photocatalyst exhibiting photocatalytic activity. Therefore, the wall surface of the room is coated with titanium oxide, and the air in the room is sterilized by photocatalytic activity by ultraviolet rays emitted from a fluorescent lamp. Attempts have been made to deodorize.
[0005]
[Problems to be solved by the invention]
However, the deodorization by natural vaporization of fragrances and deodorants has a limit on the processing capacity of one fragrance or deodorant, and there are several fragrances depending on the size of the room or the amount of odor generated. If the room is closed like at night, there is a problem that the odors of these fragrances and deodorants are strongly filled.
[0006]
Also, when sterilizing and deodorizing with an ozone generator as in a hospital, sterilization with ozone can provide excellent effects, but there is an odor peculiar to ozone, and general wards other than treatment rooms and operating rooms In the current situation, it is not used much.
[0007]
Furthermore, the forced circulation mechanism using a filter can remove fine substances floating in the air and cigarette dust, but has not yet completely eliminated chemicals and urine odors such as wards.
[0008]
On the other hand, in the form where the wall surface of the room is coated with titanium oxide and the photocatalytic activity of the ultraviolet light emitted from the fluorescent light is used to sterilize and deodorize the air in the room, it is illuminated or when sunlight enters. The effect can be obtained at certain times, but there is a problem that the effect of sterilizing and deodorizing the air in the room cannot be obtained at the time when the light is turned off such as at night.
Moreover, in the situation where the air in the room stays, there is a problem that an effective air sterilization and deodorizing effect cannot be obtained.
[0009]
The present invention was devised in view of the above points, and provides a deodorizing method and a deodorizing device for forcibly circulating and sterilizing and deodorizing air in a room with a photocatalytic activity of titanium oxide and a deodorizing agent. It is intended to do.
[0010]
[Means for Solving the Problems]
In order to achieve the above object, a deodorizing method according to the present invention includes a step of taking air into a deodorizing device by a suction fan, and a foam forming the porous layer provided on the inner wall surface of the deodorizing device. There are provided a step of sterilization and deodorization by photocatalytic activity by a titanium oxide coated on a synthetic resin and a light source emitting ultraviolet rays, and a step of discharging the sterilized and deodorized air from the inside of the deodorization apparatus.
[0011]
Here, the step of taking air into the deodorization device by the suction fan is to drive and rotate the suction fan by the driving force of the electric motor to suck the room air into the deodorization device. A foamed synthetic resin that forms a porous layer coated with titanium oxide is attached to the inner wall surface of the deodorization device, and sterilization and deodorization are achieved by the photocatalytic activity of the titanium oxide coated on the porous layer and a light source that emits ultraviolet rays. It is set as the structure discharged | emitted out of a deodorizing apparatus, performing.
[0012]
Moreover, the deodorizing method which concerns on this invention is equipped with the process of providing a deodorizing agent in the said deodorizing apparatus.
[0013]
Here, the air taken into the deodorization device by the suction fan is sterilized and deodorized by the photocatalytic activity of the foamed synthetic resin that forms a porous layer coated with titanium oxide attached to the inner wall surface of the deodorization device and the light source that emits ultraviolet rays. By supplementing with a deodorizing agent, immediate deodorization becomes possible.
[0014]
In order to achieve the above object, a deodorizing apparatus according to the present invention includes a suction fan for taking in air provided in a deodorizing apparatus body in which an air intake port and an air exhaust port are formed, and the inside of the deodorizing apparatus body. The structure includes a foamed synthetic resin having a porous layer coated with titanium oxide provided on a wall surface, and a light source for irradiating ultraviolet rays.
[0015]
Here, a suction fan that is driven and rotated by an electric motor is provided at the air intake port of the deodorizing device, and the air in the room is taken into the deodorizing device by this suction fan and discharged from the air discharge port.
[0016]
Therefore, it is formed from a foamed synthetic resin in which a porous layer coated with titanium oxide that is attached to the inner wall surface of the deodorizing device is formed while the room air is taken into the deodorizing device by the suction fan and discharged from the air discharge port. The titanium oxide filter is sterilized and deodorized by the photocatalytic activity of a light source that irradiates the titanium oxide filter with ultraviolet light.
[0017]
Moreover, the deodorizing apparatus which concerns on this invention is set as the structure by which a deodorizing agent is provided in the said deodorizing apparatus.
[0018]
Here, a suction fan that is driven and rotated by an electric motor is provided at the air intake port of the deodorizing device, and the air in the room is taken into the deodorizing device by this suction fan and discharged from the air discharge port.
[0019]
Therefore, a foamed synthetic resin in which a porous layer coated with titanium oxide attached to the inner wall surface of the deodorization device is formed while the air in the room is taken into the deodorization device by the suction fan and discharged from the air discharge port. In addition, sterilization and deodorization are performed by synergy between the photocatalytic activity of the light source that irradiates the titanium oxide filter with ultraviolet light and the deodorizer installed in the deodorizer.
[0020]
Note that the photocatalytic effect of titanium oxide exhibits the effect of photocatalytic decomposition that decomposes surrounding organic substances, bacteria, and the like by irradiating the titanium oxide with light (ultraviolet rays). The effects of this photocatalytic titanium oxide include antibacterial and antifungal action that decomposes and disinfects fungal cell membranes, reacts with odor molecules with water and air, dissolves odors, decomposes harmful gases in the air and is harmless It is configured to perform antibacterial and deodorizing of the air in the room sucked into the deodorizing device by utilizing the atmospheric hatching action.
[0021]
Deodorizers are those that are suitable for the target odor, such as those that adsorb odors such as activated carbon, those that are chemically neutralized, those that cancel out like the odor neutralization method, or aromatics. There is a method of masking odor like an agent. Further, it is desirable that these deodorizing agents use liquids, gels, or solids that gradually evaporate by being exposed to an air flow by a suction fan, and emit a fragrance that softens the air in the room together with deodorization.
[0022]
As a light source that emits ultraviolet rays, there is a fluorescent lamp that is widely used as illumination. Among these fluorescent lamps, there is a fluorescent lamp that mainly emits near ultraviolet rays (300 to 400 nm). By using this fluorescent lamp, an efficient photocatalytic decomposition effect can be exhibited.
