Are respectively arranged. A control circuit 17 and each of the above-mentioned sensors are provided inside the front part 2 of the main body, and the driving operation can be operated by the changeover switch 14.
[0005]
The upper main body 18 is sandwiched between the main body front 2 and the main body rear 4 above the main body partition wall 3 and has a negative ion emission port 19.
[0006]
Reference numeral 20 denotes a negative ion generating unit which has a negative ion generating unit 23 including a photoelectron emitting material 21 and an irradiation source 22 for irradiating the photoelectron emitting material 21 with ultraviolet rays. The negative ion generator 23 includes a photoelectron emitting material 21 and a source 22 for irradiating the photoelectron emitting material 21 with ultraviolet light. The photoelectron emitting material 21 irradiates the surface of the photoelectron emitting material 21 with ultraviolet light while irradiating the surface with the ultraviolet light. An air current is introduced into the surface of the emission material 21 to generate photoelectrons (negative ions 24) on the surface of the photoelectron emission material 21. An ultraviolet lamp 25 is used as the irradiation source 22 for irradiating the ultraviolet light. The ultraviolet lamp 25 includes a lamp part 26 having a filament and a mercury sphere therein, and a screw part 28 having a screw shape for attaching to a socket 27 made of porcelain (porcelain). Become.
[0007]
The irradiation source 22 for irradiating the ultraviolet light is connected to the control circuit 17, and controls such as intermittently turning on and off the irradiation of the irradiation source 22 and changing the irradiation intensity of the ultraviolet light from the irradiation source 22 are performed. The amount of generation is variable.
[0008]
The photoelectron emitting material 21 is a cylindrical metal material, and has been subjected to a surface treatment including a surface layer of Au (gold) on the entire surface including the cylindrical inner surface. The socket 27 to which the ultraviolet lamp 25 is attached is screwed and fixed to a fixing base 29 formed of sheet metal, and the fixing base 29 is further screwed and fixed to the lower protective cover 30. The upper protective cover 31 is attached so as to cover the lower protective cover 30 from above. The upper protective cover 31 prevents ultraviolet rays emitted from the ultraviolet lamp 25 from leaking to the outside and forms a passage through which air flows. A flow path is formed to the air flow intake port 32 and the negative ion discharge port 19 that serve as a guide for the air flow to the generator 23. A packing 33 is attached between the upper protective cover 31 and the lower protective cover 30 on the outer periphery of the cylindrical photo-emissive material 21, and the passage of the airflow is limited to the inner surface of the cylindrical photo-emissive material 21. It is air tight so that it becomes.
[0009]
The operation of the above configuration will be described. When the motor 7 is rotated by the changeover switch 14, the fan 8 connected to the motor 7 rotates and air is sucked from the front intake port 5. The sucked airflow passes through a filter 11 in which an activated carbon filter and a charging filter are combined, and is exhausted to an exhaust port 12, where the air is deodorized and purified.
[0010]
In the automatic operation, each sensor performs detection in accordance with the contamination of indoor air. The particle detection sensor 16 detects dust and the like, the odor detection sensor 15 detects odor such as cigarette smoke, and the control circuit 17 controls the motor 7 according to the output of each sensor that changes depending on the concentration, thereby reducing the air volume.

[0011]
The air exhausted to the exhaust port 12 through the filter 11 has a part of the exhaust flowing from the airflow inlet 32 of the negative ion generating unit 20 and flows into the negative ion generating unit 23. The airflow that has flowed into the negative ion generator 23 is sterilized by microorganisms and bacteria such as viruses, bacteria, yeast, and mold in the air by ultraviolet rays emitted from the ultraviolet lamp 25, and negative ions 24 are generated. That is, photoelectrons (negative ions) 24 are obtained by irradiating the photoelectron emitting material 21 with ultraviolet rays from an ultraviolet lamp 25. The thus obtained air flow that is sterilized and contains the negative ions 24 is discharged from the negative ion discharge port 19. At this time, the microorganisms and bacteria are sterilized by the airflow exhausted into the room through the exhaust port 12, and the airflow containing the negative ions 24 is diffused throughout the room, thereby removing the microorganisms and bacteria in the room. The amount gradually decreases, and the air becomes clean air. At the same time, the negative ions 24 electrically neutralize the fine particles and the like or take a negative charge to provide a stable indoor space.
[0012]
[Problems to be solved by the invention]
However, in the above-described conventional air conditioner, a part of the exhaust gas flows into the negative ion generating unit 23 from the air flow inlet 32 of the negative ion generating unit 20 and flows into the negative ion generating unit 23. And bacteria are sterilized, and negative ions 24 are generated. However, since the air flow passes only through the inner surface of the cylindrical photoelectron emission material 21, the cross-sectional area of the air flow is very narrow, and the air outlet is formed. Only a very small part of the exhaust gas exhausted into the room through 12 can flow into the negative ion generating section 23, and the microorganisms and bacteria are sterilized and the air current containing the negative ions 24 is diffused throughout the room. There was a problem that it took a very long time to complete. Further, since the passage cross-sectional area of the airflow is very narrow, the exhaust resistance (pressure loss) at the exhaust port 12 increases, which causes a problem that the air volume of the air conditioner decreases and the noise value increases. Was.
[0013]
Next, the socket 27 to which the ultraviolet lamp 25 is attached is screwed and fixed to a fixing base 29 formed of sheet metal, and the fixing base 29 is further screwed and fixed to the lower protective cover 30. In other words, the ultraviolet lamp 25 is not only held on one side but also held by a rigid body. Therefore, when the air conditioner body is turned over during use or dropped when carrying, Therefore, there is no portion for absorbing the impact, and the impact is transmitted to the ultraviolet lamp 25 or the socket 27 as it is, and the ultraviolet lamp 25 is damaged by the impact. Further, since the ultraviolet lamp 25 is held on only one side, the glass portion at the tip of the ultraviolet lamp 25 deflects due to an impact and hits the inner surface of the cylindrical photoelectron emitting material 21, causing a problem that the glass portion is damaged.
[0014]
In addition, the ultraviolet light of the ultraviolet lamp 25 is reflected on the main body wall around the negative ion outlet 19 and the wall of the passage including the negative ion generator 23 to the negative ion outlet 19 and leaks from the negative ion outlet 19 to the outside. There was a problem.

To create a space that does not impair the metabolic and physiological functions of the living body, and to generate negative (negative) ions to electrically neutralize fine particles etc. or to take a negative charge to create a stable space. The purpose is to provide.
[0016]
Another object of the present invention is to prevent the ultraviolet lamp from being damaged by an impact due to a fall or a fall of the main body.

The protective cover 91 is attached so as to cover the sterilizing and negative ion generating unit 77 from above, and prevents ultraviolet rays emitted from the ultraviolet lamp 82 from leaking to the outside and forms a passage through which air flows. In addition, a flow path is formed to an air flow intake port 92 and a negative ion discharge port 71 that serve as a guide for the air flow to the negative ion generating section 80. The exhaust passage provided with the irradiation source 79 for irradiating the ultraviolet rays is formed in a step-like manner, and the exhaust passage is bent in a step-like manner, so that the exhaust flow of the main body wall around the negative ion emission port 71 and the negative ion generator 80 is formed. The ultraviolet light of the ultraviolet lamp 82 is reflected on the wall surface of the passage including the inlet 92 to the negative ion outlet 71 to prevent the ultraviolet light from leaking from the negative ion outlet 71 and the airflow inlet 92 to the outside.

[0081]
Numeral 93 denotes an anti-reflection member made of a low-reflectance flame-retardant dark-colored member adhered to the stepped exhaust passage wall surface. This is for preventing leakage to the outside from the air intake 71 and the air flow inlet 92.
[0082]
The air flow inlet 92 of the sterilizing and negative ion generating unit 77 is provided along the shape of the tongue portion 94, and an anti-reflection body 93 is also attached on the tongue portion 94.
[0083]
Reference numeral 95 denotes an eave A formed at the upper part of the protective cover 91 on the side of the negative ion emission port 71, that is, on the downstream side of the exhaust gas flow. Has been prevented. In addition, ultraviolet rays are prevented from irradiating other components in the vicinity of the negative ion discharge port 71 and water is prevented from being applied to the negative ion generator 80 even when water enters from the outside.
[0084]
Reference numeral 96 denotes an eave B formed below the protective cover 91 on the side of the airflow inlet 92, that is, on the upstream side of the exhaust air flow. Like the eaves A95, the eaves B prevent the irradiation source 79 from direct viewing and irradiate other parts with ultraviolet rays. Preventing. Further, the eaves A95 and the eaves B96 are formed integrally with the protective cover 91 by bending, so that the eaves can be formed at a low cost without forming the eaves part as a separate component.
[0085]
Further, the eaves A95 and the eaves B96 are provided on both the upstream side and the downstream side of the negative ion generating section 80, but may be provided on only one of the upstream side and the downstream side, and the same effect is obtained.
[0086]
Reference numeral 97 denotes a holding unit that holds a power supply line 85 that supplies power to the electrode 83a of the ultraviolet lamp 82, and is provided near the support of the ultraviolet lamp 82 that is the irradiation source 79.
[0087]
The operation of the above configuration will be described. When the motor 58 is rotated by the changeover switch 66, the fan 59 connected to the motor 58 rotates, and air is sucked from the front intake port 55 and the rear intake port 56. The sucked air flow passes through a filter 62 in which an activated carbon filter and a charging filter are combined, and is exhausted to an exhaust port 63, where the air is deodorized and purified.
[0088]
In the automatic operation, each sensor performs detection in accordance with the contamination of indoor air. The particle detection sensor 69 detects dust and the like, the odor detection sensor 68 detects the smell of tobacco smoke and the like, and the control circuit 70 controls the motor 58 in accordance with the output of each sensor that changes depending on the concentration, thereby driving the motor. Do.
[0089]
Then, the air exhausted to the exhaust port 63 through the filter 62 is partly exhausted from the air flow inlet 92 of the sterilizing and negative ion generating unit 77 provided along the shape of the tongue portion 94 and the air is exhausted. It flows into the ion generator 80. In the airflow that has flowed into the negative ion generating section 80, viruses and bacteria such as viruses, bacteria, yeast, and mold in the air are killed by ultraviolet rays emitted from the ultraviolet lamp 82, and negative ions 81 are generated. That is, photoelectrons (negative ions) 81 are obtained by irradiating the photoelectron emitting material 78 with ultraviolet rays from an ultraviolet lamp 82. The thus obtained air flow that is sterilized and contains the negative ions 81 is discharged from the negative ion discharge port 71. At this time, the microorganisms and bacteria are sterilized by the airflow exhausted into the room through the exhaust port 63, and the airflow containing the negative ions 81 is diffused throughout the room, and the microorganisms and bacteria in the room are removed. The amount gradually decreases, and the air becomes clean air. At the same time, the negative ions 81 electrically neutralize the fine particles and the like or take a negative charge to provide a stable indoor space.
[0090]
By making the longitudinal direction of the ultraviolet lamp 82 as the irradiation source 79 substantially perpendicular to the flow direction of the exhaust gas and expanding the exhaust flow path in the longitudinal direction of the irradiation source 79, the passage cross-sectional area of the airflow is very large. Therefore, the range of sterilizing the exhaust gas flow by irradiating ultraviolet rays and the size of the negative ion generating section 80 can be increased, and the flow into the negative ion generating section 80 can be further increased. Therefore, only a very small part of the exhaust gas exhausted into the room through the exhaust port 63 can flow into the negative ion generating section 80, and microorganisms and bacteria are sterilized, and the airflow containing the negative ions 81 is generated in the entire room. The problem that it takes a very long time to be diffused to the room can be solved, and the entire room can be quickly diffused. Therefore, by generating clean air in which microorganisms and bacteria are sterilized and ozone-less negative ions in the indoor space at an early stage, a space that does not impair the metabolic function and physiological function of the living body is created. By generating ions, the fine particles and the like can be electrically neutralized or charged negatively to provide a stable space.
[0091]
Further, since the passage cross-sectional area of the airflow can be made very large, the exhaust resistance (pressure loss) at the exhaust port 63 can be reduced, and the airflow as an air conditioner can be secured and the noise value can be increased. Can be suppressed.
[0092]
Further, by supporting both ends of the ultraviolet lamp 82 as the irradiation source 79, the ultraviolet lamp 82 is held by only one side and thus bends due to an impact, so that the glass part of the lamp 83 of the ultraviolet lamp 82 hits nearby parts and the glass part Can be prevented from being damaged, and the ultraviolet lamp 82 can be prevented from being damaged by an impact due to a fall or a fall of the main body.
[0093]
Since the ultraviolet lamp 82 as the irradiation source 79 is supported by sandwiching both ends of the ultraviolet lamp 82 between the support rib 89 of the main body partition wall 51 and the flange portion 90 of the photoelectron emission material 78, only one side of the ultraviolet lamp 82 is held. This prevents the problem that the glass portion of the lamp 83 of the ultraviolet lamp 82 hits a nearby component and is damaged by the impact, and the glass portion is damaged, and the ultraviolet lamp 82 is damaged by an impact due to a fall or a fall of the main body. Can be prevented.
[0094]
Further, by supporting both ends of the ultraviolet lamp 82 as the irradiation source 79 via a holding portion 84 made of an elastic material such as rubber, a shock caused by a fall or a drop of the main body can be prevented by a holding portion made of an elastic material such as rubber. It absorbs at 84 and the impact is transmitted to the ultraviolet lamp 82 as it is, thereby preventing the ultraviolet lamp 82 from being damaged by the impact.
[0095]
Further, since the holding portion 97 of the power supply line 85 to the irradiation source 79 is provided near the support portion of the irradiation source 79, even if the ultraviolet lamp 82 as the irradiation source 79 is damaged, the electrode portions 83a at both ends of the ultraviolet lamp 82 are not damaged. It can be prevented from hanging down and coming into contact with a nearby metal part.
[0096]
The exhaust passage is bent in a stepwise manner so that the ultraviolet light of the ultraviolet lamp 82 is applied to the wall surface of the main body around the negative ion discharge port 71 and the wall surface of the passage including the air flow inlet 92 of the negative ion generator 80 to the negative ion discharge port 71. Can be prevented from leaking to the outside through the negative ion discharge port 71 and the airflow inlet 92.
[0097]
Then, the ultraviolet lamp 82 as the irradiation source 79 is located almost in the middle of the exhaust passage from the airflow intake port 92 of the negative ion generator 80 to the negative ion emission port 71 which is bent in a stepwise manner. And leakage of ultraviolet light from both sides of the negative ion discharge port 71 can be prevented.
[0098]
Further, by providing the antireflection body 93 of low reflectance on the wall surface of the stepped exhaust passage, from the body wall around the negative ion discharge port 71 and the airflow inlet 92 of the negative ion generator 80 to the negative ion discharge port 71. Can be prevented from being reflected from the wall surface of the passage containing the ultraviolet rays of the ultraviolet lamp 82 and leaking to the outside through the negative ion discharge port 71 and the airflow inlet port 92.
[0099]
In addition, since the wall surface has a low reflectance, not only the ultraviolet light from the ultraviolet lamp 82 but also the visible light can be prevented from leaking from both sides of the airflow intake port 92 and the negative ion discharge port 71, so that it can be used in a dark room at night. It does not matter if it is done.
[0100]
And, in order not to be bothered even when used in a dark room at night, the visible light leaking from the negative ion emission port 71 and the exhaust port 63 needs to be suppressed to 20 lux or less, preferably to 10 lux or less. It needs to be suppressed. If it is suppressed to 20 lux or less, it does not matter if it is used in a dark room at night, such as at bedtime.
[0101]
In addition, since the low-reflection anti-reflection member 93 is made of a dark-colored member having flame retardancy, similarly, the problem that ultraviolet rays are reflected and leak to the outside through the negative ion emission port 71 and the airflow intake port 92 is prevented. In addition, since it has flame retardancy, it is possible to prevent mechanical deterioration due to ultraviolet rays from the ultraviolet lamp 82 and heat radiation. Furthermore, even if the ultraviolet lamp 82, which is the irradiation source 79, is broken and the electrode 83a comes into contact with the anti-reflection member 93 having a low reflectance, the electrode 83a has flame retardancy, and there is no risk of ignition.
[0102]
Also, an eave A95 formed on the downstream side of the exhaust flow above the protective cover 91, an eave B96 formed on the upstream side of the exhaust flow below the protective cover 91, and an eave on both the upstream and downstream sides of the irradiation source 79. This prevents the irradiation source 79 from being directly viewed even when looking through the negative ion emission port 71 and the exhaust port 63, and also irradiates other parts near the negative ion emission port 71 and the airflow intake port 92 with ultraviolet rays. In addition, it is possible to prevent the negative ion generating section 80 from being exposed to water even when water enters from the outside.
[0103]
Further, the eaves A95 and the eaves B96 are formed integrally with the protective cover 91 by bending, so that the eaves can be formed at a low cost without being formed by forming the eaves part with another sheet metal part and then attaching it by spot welding or the like. Can be done.
[0104]
Further, the eaves A95 and the eaves B96 are provided on both the upstream side and the downstream side of the negative ion generating section 80, but may be provided on only one of the upstream side and the downstream side, and the same effect is obtained. .
[0105]
Further, since the photoelectron emitting material 78 on which gold plating, gold deposition, or the like has been applied has a negative potential, photoelectrons generated from the photoelectron emitting material 78 are electrically repelled from the negative potential of the photoelectron emitting material 78, and the photoelectrons are converted into photoelectrons. Return to the release material 78 can be prevented, and as a result, the amount of generation of the negative ions 81 can be increased.
[0106]
In addition, since the length of the negative ion discharge port 71 in the longitudinal direction is set to 50% or more of the length of the exhaust port 63 in the longitudinal direction, a large amount of exhaust air discharged from the negative ion discharge port 71 can be secured, and microorganisms and bacteria As a result, the air stream containing the negative ions 81 can be more effectively diffused throughout the room.
[0107]
Since the negative ion discharge port 71 and the exhaust port 63 are provided substantially parallel to each other, the resistance to airflow blowout at the negative ion discharge port 71 is reduced, microorganisms and bacteria are sterilized, and negative ions 81 are contained. The air current can be smoothly exhausted from the negative ion discharge port 71, and the noise due to the exhaust blow can be reduced by reducing the blow resistance.
[0108]
Furthermore, since the grid line in the longitudinal direction of the negative ion discharge port 71 is made to follow the outer shape of the main body, similarly, the blowing resistance of the airflow at the negative ion discharge port 71 portion is reduced, and microorganisms and bacteria are reduced. As a result, the airflow containing the negative ions 81 can be smoothly diffused throughout the room and the external appearance of the main body can be improved.
[0109]
In addition, since the height of the lattice rib 71a of the negative ion discharge port 71 is formed to be 4 mm, the exhaust flow that is likely to become turbulent in the stepped exhaust passage or the eaves is rectified by the negative ion discharge port 71 and externally. Can be released. Here, the height of the lattice rib 71a is 4 mm, but the range is preferably 4 to 10 mm. By setting the height of the lattice rib 71a to 4 to 10 mm, the same effect as above can be obtained. It is.
[0110]
A suitable amount of a part of the airflow from the electric blower including the motor 58 and the fan 59 is passed through the negative ion generator 80 from 0.5% to 15% of the airflow from the electric blower. , Preferably 0.5% to 5%. In addition, the air volume value is 0.05 m ³ / M to 1.0m ³ Per minute, preferably 0.1 m ³ / M to 0.5m ³ / Min air volume is suitable. If the amount of airflow that passes through the negative ion generating section 80 increases, the amount of air that sterilizes microorganisms and bacteria such as viruses, bacteria, yeasts, and molds in the air by ultraviolet rays increases, and the amount of negative ions 81 generated increases. However, the air flow of the air conditioner itself will be reduced due to the pressure loss, so the air intake and exhaust volume of the air conditioner body will decrease, not only the deodorization and purification performance of the indoor air will decrease, but also sterilization and generation of negative ions 81 will occur. Even if the amount is increased, the diffusion into the room and the decrease in emission will be caused. 0.5% to 15% or 0.05m of the air flow when sterilization and the generation amount of negative ions 81 are increased and the deodorization and purification performance of indoor air is somewhat sacrificed. ³ / M to 1.0m ³ / Min is suitable, but 0.5% to 5% or 0.1m ³ / M to 0.5m ³ It is preferable to generate a large amount of air to be sterilized and negative ions 81 while maintaining a cleansing effect without causing a pressure loss of the air flow through the air flow per minute, and to stabilize the air volume to be sterilized and the amount of generated negative ions 81. By setting the pressure in the range described above, a large amount of air to be sterilized and negative ions 81 are generated while ensuring the cleaning effect without causing pressure loss of the airflow, and the amount of air to be sterilized and the amount of generated negative ions 81 are stabilized. Can be made.
[0111]
Since the airflow inlet 92 of the sterilization and negative ion generation unit 77 is provided along the tongue portion 94 against which the airflow from the electric blower including the motor 58 and the fan 59 collides most frequently, the airflow has a tongue shape. The air can flow smoothly into the air inlet 92 along the path, and a large amount of sterilized air and a large number of negative ions 81 can be generated and released.
[0112]
The protective cover 91 is attached so as to cover from above and protects the inside of the negative ion generating section 80 therein, so that ultraviolet rays emitted from the ultraviolet lamp 82 do not leak outside and form a passage through which air flows. Thus, a flow path is formed to an air flow intake port 92 and a negative ion discharge port 71 which serve as a guide for the air flow to the negative ion generating section 80. The above configuration prevents ultraviolet rays emitted from the irradiation source 79 from leaking to the outside of the main body, and prevents the ultraviolet rays emitted from the irradiation source 79 from flowing to the airflow intake port 92 and the negative ion emission port 71 serving as a guide for the airflow to the negative ion generating section 82. A road is formed.
[0113]
The material of the protective cover 91 is made of a metal such as a galvanized steel plate or a color steel plate, and prevents the material from being deteriorated by ultraviolet rays irradiated from the irradiation source 79. Here, a galvanized steel plate, a plated steel plate such as a color steel plate, or a painted steel plate is given, but other materials may be used as long as the material is not easily deteriorated by ultraviolet rays irradiated from the irradiation source 79. Good. In consideration of the case where the user looks through the exhaust port 63, if a color steel plate having a color close to the main body color is used, the color becomes a protection color and the appearance is not defective.
[0114]
Further, the material of the protective cover 91 may be formed of a material obtained by adding an ultraviolet absorber to a synthetic resin. In this case, the deterioration of the material with respect to the ultraviolet light irradiated from the irradiation source 79 is performed by adding the ultraviolet absorber. Therefore, the protective cover 91 is generally formed by a resin molding process using a metal mold, which facilitates processing and molding and can be provided at low cost. As a material of the synthetic resin, polycarbonate, acrylic, or the like is suitable.
[0115]
Further, although brass (brass) is used for the photoelectron emitting material 78, brass (brass) has a feature that it has excellent conductivity and can be easily subjected to a surface treatment having an Au layer such as plating and vapor deposition. In order to stably obtain a large amount of the negative ions 81, it is most important that the photoelectron emitting material 78 conducted to the control circuit 70 has excellent conductivity and continuously emits photoelectrons. For this reason, materials such as brass, bronze, and phosphor bronze having excellent conductivity are suitable for the photoelectron emitting material 78. These materials also have excellent adhesion during plating and vapor deposition, and have a surface having an Au layer. Processing can be easily performed.
[0116]
Also, the photoelectron emission material 78 is integrally formed with a terminal connection portion 87 and a terminal 88 connected to the control circuit 70. Therefore, it is not necessary to provide a terminal connection portion as a separate component, so that the photoelectron emission material 78 can be formed at low cost. You can do it.
[0117]
An irradiation source 79 for irradiating ultraviolet rays is connected to a driving circuit 86, and the driving circuit 86 is further connected to a control circuit 70. Control such as changing the irradiation intensity is performed. First, when the irradiation of the irradiation source 79 is intermittently turned on and off, the ultraviolet lamp 82 as the irradiation source 79 is turned on and off intermittently. The life of the ultraviolet lamp 82 as the irradiation source 79 can be prolonged as a whole, and excessive emission of the negative ions 81 can be adjusted and controlled.
[0118]
Next, when the irradiation intensity of the ultraviolet light from the irradiation source 79 is changed, if the irradiation intensity of the ultraviolet light is increased, the bactericidal power for sterilizing microorganisms and bacteria such as viruses, bacteria, yeasts, and molds in the air is improved, The generation amount of the negative ions 81 increases, and if the irradiation intensity decreases, the bactericidal power for sterilizing microorganisms and bacteria weakens, and the generation amount of the negative ions 81 decreases. By varying the intensity, it is possible to control the disinfecting power for disinfecting microorganisms and bacteria and the amount of generated negative ions 81, and to use the environment such as temperature and humidity, and the odor detection sensor 68 and the particle detection sensor 69. The ultraviolet irradiation intensity of the irradiation source 79 is varied according to the usage state such as the degree of contamination of the indoor air detected by the method, thereby killing microorganisms and bacteria. Can be variably controlling the generation amount of force and negative ions 81 may be a sterilizing power and the generation of negative ions 81 close to nature.
