Definitions
- the present invention relates to an air purifying apparatus and an air purifying method in which negative ions and ozone coexist at low concentrations.
- Air purifiers maintain a good indoor environment by circulating dirty air in a room with a blower fan while filtering the air.However, in recent years, the action of minus ion, At the same time, the air purifying device has been attracting attention for its effects such as blood purification, mental stability, recovery from fatigue, etc. (hereinafter, these are collectively referred to as relaxation effects). The use of those with embedded is spreading.
- sterilizers and sterilizers that utilize the sterilizing effect of ozone are well known. However, the ozone concentration when used for this purpose is for example 1
- % Or more is usually selected, and this concentration is harmful to the human body.
- ozone has been actively used in air purifiers for the purpose of sterilizing indoor air by utilizing the sterilizing effect of ozone or controlling bacteria to suppress the growth of bacteria. Rather, it was removed as a harmful component.
- Japanese Patent Application Laid-Open No. 2001-259,470 describes an example of an air purifier that decomposes and removes ozone generated along with negative ions by high pressure discharge with a catalyst.
- Japanese Patent Publication No. 0 0-1 4 0 6 8 8 discloses an example of an air-in purifier and an air-conditioning apparatus in which ozone generated as a by-product together with a minasion by high-pressure discharge is effectively used for sterilization in the apparatus. Is recorded. Also, “Japan Antibacterial and Fungicide", Vol. 27, No. 1, No. 7
- mm statement 2 there is a report discussing that the combined use of ozone and negative ions can improve the bactericidal effect, but it has a low concentration that does not adversely affect the human body and indoor equipment. No mention is made of the coexistence of negative ions and ozone. .
- the present invention has been made based on the hint of the report of the above-mentioned paper, and makes full use of the relaxation effect obtained by minus ion, and furthermore, coexists with ozone to make use of its bactericidal activity. The objective was to enhance the sterilizing or bacteriostatic action of the equipment and create a good indoor environment. Disclosure of the invention
- an air purifying apparatus provides an air purifying apparatus including a negative ion generating means and a means for circulating indoor air, wherein the average value of the ozone concentration in the indoor atmosphere is set to 0. Equipped with an on-generation means having an ability of 0.2 to 0.05 ppm.
- the air purifying method of the present invention uses the above-described air purifying device to circulate and stir room air to create a good indoor environment. If the ozone concentration is within the above range, the odor is strong, and there is no adverse effect on the human body such as headaches caused by people in the room. The effect of higher level, sterilization or bacteriostatic action is exhibited.
- the relaxation action of minusion that is, the action of purifying blood, stabilizing the god, and recovering from fatigue as well as making the person feel refreshed, can create a good indoor environment.
- negative ion generating means capable of keeping the average value of the minus ion concentration in the vicinity of the airflow outlet at 200,000 to 100,000 / min, adverse effects such as the failure of indoor equipment may be avoided. Therefore, it is possible to obtain an air purifying device suitable for use in an environment where people are present. Negative ions rapidly disappear as they move away from the outlet of the generator, and their concentration decreases, but the amount remaining at a location relatively close to the outlet depends to some extent on the amount generated by the generator.
- the negative ion generating means in the apparatus of the present invention has the ability to maintain the average negative ion concentration in the vicinity of the airflow outlet at 200,000 to 100,000. It is judged that it is desirable to use one that does. As a result, negative ions and ozone can coexist at a low concentration that does not adversely affect the human body and indoor equipment, and the intended effect can be exerted.
- FIG. 1 and FIG. 2 are graphs for explaining the above judgment, and show the relationship between ozone concentration (horizontal axis) and kill ratio (vertical axis) using minus ion concentration as a parameter. It is a thing. These graphs are based on the data disclosed in article 1 above.
- Fig. 1 is for Staphylococcus aureus and Fig. 2 is for the large intestine.
- Solid lines A and B are normal air (minus ion concentration is assumed to be 150 to 200 cells / CC). The concentration of the minasion
- the broken line is the middle 30,000 pieces cc, 200,000 pieces / ( ⁇ , 250,000 pieces / cc, 500,000 pieces and 100,000 pieces / cc.
- the dashed line is an estimated line, since only the data for the ozone concentration of 0.03 ppm is disclosed in Article 1 except for the solid lines A and B.
- the sterilization rates of the solid lines B are all high. In other words, in a gas mixture in which minus ion and ozone coexist, even if the ozone concentration is lower than that of the case where ozone is used alone for the purpose of sterilization and germicidal removal alone, it is several times to 10 times or more. It has been shown that a bactericidal effect can be obtained.
- the inventor of the present application paid attention to a low-concentration region which was completely excluded from the subject for the sterilization apparatus and which had no adverse effect on the human body.
- the lower limit of the concentration at which near 0.3% bacilli can be obtained at 0.03 ppm that is, 200,000 _ cc
- the upper limit is 0.05 ppm, where no odor is felt and no headaches occur.
- the lower limit was set at 0.02, at which a sterilization rate of 30% or more was secured at a negative ion concentration of 100,000 particles / m2.
- the bactericidal rate differs depending on the type of bacteria. This is a report of the results that have passed.
- the present application In light of the above, the generated negative ions spread into the indoor atmosphere and decrease in concentration, so that contact with relatively high concentrations of negative ions promotes sterilization or bacteriostatic action because the airflow containing ozone is It is considered that this is only a short time until it is released through the negative ion generating means. Therefore, the conditions are different from those of a paper whose atmosphere is always kept at a predetermined concentration, and it goes without saying that the data of the paper cannot be directly applied to the present invention.
- Fig. 3 illustrates the relationship between the distance from the outlet and the density of minus ions.
- a wooden table with a height of 85 cm was installed in the center of the work place with a floor of 4 m X l 5 m and a height of 3 m to the ceiling, and the air volume was 1.4 m 3 / min Place the negative ion generator and blow out the air current horizontally, and measure it at the same height (Andes Electric
- the negative ion concentration was measured at I CT (201 A). As shown in the figure, there was a situation in which the minus ions, which had a concentration of 100,000 ions / cc at the position of 10 cm from the blowout rocker, rapidly disappeared and decreased with distance. I have.
- the concentration of negative ions in the indoor atmosphere rapidly decreases at a position away from the outlet.
- the capacity of the negative ion generating means that is, the amount of ion generated, varies not only with the concentration near the outlet but also with the air flow rate and speed, and the concentration in the indoor atmosphere is determined by the air purifier. It also depends on the size of the room to be installed. However, when returning to the air purifier after going around the room, the concentration of negative ions in the airflow when sucked into the negative ion generating means is 200,000 to 100,000 in the vicinity of the outlet as described above. In the range of / cc, it was almost 700 pieces / cc regardless of the air volume and the size of the room.
- the negative ion concentration in the room some distance from the generation means is stable at about 700 cc. This concentration is about three times the value in the suburbs and almost the same as the value in mountainous areas, and is a value that can provide a sufficient relaxation effect.
- Figure 1 is a graph showing the relationship between the ozone concentration and the disinfection rate and minus ion concentration.
- Fig. 2 is a graph showing the relationship between ozone concentration, sterilization rate and negative ion concentration.
- Fig. 3 is a graph showing the relationship between the distance from the outlet and the concentration of minasung.
- FIG. 4 is a diagram showing a configuration of an apparatus according to an embodiment of the present invention.
- reference numeral 1 denotes a main body of the apparatus, which includes a negative ion generator 2 for generating negative ions, an ozone generator 3 for generating ozone, a fan 4, a control unit 5 having a CPU, and a power supply unit (not shown). ), And has a suction port 6 and a discharge port 7.
