In the case of applying the antistatic paint, the antistatic treatment can be performed by performing the painting work treatment for the appearance decoration of the product, and it is not necessary to perform the antistatic agent coating work as a separate work process. The antistatic treatment can be performed very easily and easily.

As in the present embodiment, the negative ion emission port 7
If the main body 54 having 1 is formed of an antistatic resin material, a separate process work such as application of an antistatic agent or application of an antistatic paint is not required, and a part having a negative ion emission port such as a mold can be formed. The antistatic treatment can be applied only by molding.

The main body 54 having the negative ion emission port 71 can be made into a very simple plate-like shape, and since it is not a complicated shape, work such as application of antistatic agent or application of antistatic paint is performed. In addition to being easy to perform, it is possible to obtain a good product with good moldability and stability even when formed of an antistatic resin material.

Similarly, the main body partition wall 51 forming the passage for negative ions including the negative ion generation portion 80 to the negative ion emission port 71 is also formed of an antistatic resin material, and the surface resistance value of its wall surface is 10. ^{8-10 12}
Ω has been subjected to antistatic treatment. By applying an antistatic treatment of the surface resistance value of the passage wall surface of the negative ions including the negative ion generation portion 80 to the negative ion emission port 71 to 10 ⁸ to 10 ¹² Ω, the negative ion generation portion 8
Ozone-less negative (negative) ions generated at 0 are prevented from being neutralized and disappeared by the negative (+) positively charged negative ion emission port 71 due to friction of the exhaust flow, and disappear through the exhaust port 53. The negative ions 81 can be diffused in the entire room by being carried on the air flow exhausted to the air, and the negative ions 81 can be generated to electrically neutralize the fine particles or give a negative charge to provide a stable indoor space. Can be done.

Here, the surface resistance of the wall surface is set to 10 ⁸ to 10 ¹² Ω with the antistatic resin material, but even if the antistatic treatment is applied by applying an antistatic coating, that is, coating or applying an antistatic agent. Good. The antistatic agent can be applied very easily and easily by applying an antistatic agent to a cloth or cotton and lightly wiping the main body partition wall 51, or by applying an antistatic treatment such as spraying or dipping (immersion). It can be treated.

In the case of applying the antistatic paint, the antistatic treatment can be performed by performing the painting work treatment for the appearance decoration of the product, and it is not necessary to perform the antistatic agent coating work as a separate work process. The antistatic treatment can be performed very easily and easily.

As in this embodiment, the negative ion generator 8
If the main body partition wall 51 that forms the passage of the negative ions including 0 to the negative ion emission port 71 is formed of the antistatic resin material, separate process work such as application of the antistatic agent and application of the antistatic paint is required. Instead, the antistatic treatment can be performed only by molding a component having a negative ion emission port with a mold or the like.

Further, the opening lid 91 is screwed to a lid 93 which is detachably attached to a maintenance opening 63a provided in a part of the exhaust port 63, and the lid 93 is removed from the outside of the main body. As a result, it can be removed from the protective cover 90 together with the lid 93. The opening lid 91 together with the lid 93 is removed from the protective cover 90, and a hand is put through the opening 63a to maintain the photoelectron emitting material 78 that constitutes the negative ion generating portion 80, the ultraviolet lamp 82 that is the irradiation source 79, and the socket 84. Can be done easily. That is, maintenance such as replacement of parts due to filament breakage of the ultraviolet lamp 82, cleaning of the inner surface of the photoelectron emitting material 78 and surface of the ultraviolet lamp 82, and the like are provided in a part of the exhaust port 63 for maintenance 63 a. By simply removing the lid 93 detachably attached to the main body from the main body, the maintenance work can be easily performed from the outside of the main body without disassembling and disassembling the main body.

Further, a concave central portion 50a is provided on the front surface of the main body, and the front surface of the main body is curved.
Is composed of a plate-shaped printed circuit board 70a, so that the control circuit 70
The distance from the light-emitting body 76 arranged above to the front display unit 65 is not constant. Therefore, the transparent rods 65a having different heights up to the display surface of the display unit 65 of the light-emitting body 76 of the same height are brought close to the light-emitting body 76 of the same height, and the brightness of the light-emitting body 76 is adjusted according to the height of the transparent rod 65a. Is changed by the control circuit 70. That is, the higher the height of the transparent rod 65a (the farther the distance to the display surface is), the greater the brightness of the light-emitting body 76 is made to be brighter so that the display brightness of the display surface of the display unit 65 is uniform. I am trying to become.

Here, the shape of the transparent rod 65a is substantially conical, but it may be a polygonal tube or a polygonal pyramid. When the transparent rod 65a is substantially conical, the light emitting body 76 is formed.
The light from can be diffused along a substantially conical shape,
The light emitting area of the light emitting body 76 can be displayed in a state in which it is diffused in a wider area on the display surface of the display unit 65. Also,
When the transparent rod has a polygonal tube shape or a polygonal pyramid shape, one light emitting body 76 can emit light to each side of the polygon, and one light emitting body 76, here an LED (light). Multi-faceted display can be expressed with an emitting diode). Further, in the case of the polygonal cone, the light from the light emitting body 76 can be further diffused along the shape of the polygonal cone, and the light emitting area of the light emitting body 76 can be diffused to a wider area on the display surface of the display unit 65. It can be displayed in a closed state.

Further, since it is provided on the outer surface of the main body of the lamp display unit 67 for notifying the operating state of the negative ion generating unit 80 and the change in the air volume, the irradiation of the irradiation source 79 is intermittently turned on and off, or the ultraviolet irradiation of the irradiation source 79 is performed. The particle detection sensor 69 detects a change in the operating state of the negative ion generation unit 80 that changes the generation amount of the negative ions 81 and dust, etc. by performing control such as changing the intensity, and smells of cigarette smoke and the like. The odor detection sensor 68 detects the odor, and the control circuit 70 controls the motor 58 according to the output of each sensor which changes depending on each concentration to display the operating state of the variable operation in which the air volume is increased or decreased in an easily understandable manner from the outside of the main body. You can

On the wall surface of the negative ion passage including the negative ion generating portion 80 and the negative ion emitting port 71, a layer 99 of low reflectance made of black non-woven fabric is provided. It is possible to prevent ultraviolet rays from leaking from the negative ion emitting port 71 to the outside by reflecting the ultraviolet rays of the ultraviolet lamp 82 on the wall surface of the main body and the wall of the negative ion passage including the negative ion generating unit 80 to the negative ion emitting port 71. is doing. Although a black non-woven fabric is used here, felt, urethane foam, velvet, or the like may be used, or a film with low reflectance such as painting or plating on the wall may be provided. A rate of 0% to 20% is suitable, and a reflectance of 0% to 10% is preferred.

Reference numeral 100 denotes a protruding rib for preventing the deformation of the eaves A97, which is provided so as not to be deformed downward even when the eaves A97 is pushed through the negative ion emission port 71 by a rod or the like thinner than the outside. When the eaves A97 is deformed downward, the passage of the negative ions from the negative ion generation portion 80 to the negative ion emission port 71 is narrowed, so that the generation amount of the negative ions 81 may decrease.

Since the vortex chamber 57 is arranged in the vertically long main body and the exhaust port 63 communicating with the upper side is formed so as to expand to the full width of the main body, the exhaust pressure loss can be suppressed to a low level and the air volume can be improved. Low noise can be realized. Also, power cord 1
No. 01 can store a cord with an extra length in the space below the vortex chamber 57 depending on the installed state. In addition, the motor 58
Is wired in the lateral direction of the vortex chamber 57 and the power cord 1
It is processed in the side part of the main body together with 01, which facilitates the work of processing the lead wire.

Above protective cover 90, below protective cover 89
The material is made of metal such as galvanized steel plate and color steel plate, and prevents the material from being deteriorated by the ultraviolet rays emitted from the irradiation source 79. Here, a galvanized steel plate, a plated steel plate such as a color steel plate, and a coated steel plate are given, but other materials may be used as long as they are materials that are not easily deteriorated by the ultraviolet light emitted from the irradiation source 79. Good. Considering the case of looking through the exhaust port 69, if a color steel plate having a color close to the color of the main body is used, the color becomes a protective color and there is no problem in appearance.

The material of the upper protective cover 90 and the lower protective cover 89 may be formed of a material obtained by adding an ultraviolet absorber to a synthetic resin. In that case, the material for the ultraviolet light emitted from the irradiation source 79 may be changed. Deterioration is prevented by adding an ultraviolet absorber, and because it is a synthetic resin,
The processing of the protective cover upper part 90 and the protective cover lower part 89 is generally a resin molding process using a mold, which facilitates the processing and molding and can be provided at a low cost. Polycarbonate, acrylic, etc. are suitable as the material of the synthetic resin.

The photoelectron emitting material 78 is made of a cylindrical metal material, brass (brass) in this case, and the entire surface including the cylindrical inner surface is surface-treated with an Au (gold) layer. There is. In addition, the photoelectron emitting material 78 has a terminal connecting portion 8
6 is integrally formed, and a terminal 87 that is electrically connected to the control circuit 70 is connected to the control circuit 70.

Then, according to the above, the surface of the UV lamp 82, which is the irradiation source 79, is wrapped around the UV lamp 82 in a cylindrical shape at a uniform distance, and the surface having the Au layer on the inner surface separated from the surface of the UV lamp 82 by a uniform distance. By irradiating the treated cylindrical photoelectron emitting material 78 with ultraviolet rays having a uniform irradiation intensity, a large number of negative ions 81 can be stably generated.

The photoelectron emitting material 787 is made of brass.
However, brass (brass) is excellent in conductivity and has a feature that it is easy to perform surface treatment having an Au layer such as plating and vapor deposition. In order to stably obtain a large amount of negative ions 81, it is most important that the photoelectron emitting material 78 that is conducted to the control circuit 70 has excellent conductivity and always emits photoelectrons. Therefore, materials such as brass, bronze, and phosphor bronze having excellent conductivity are suitable for the photoelectron emitting material 78, and these materials also have excellent adhesion at the time of plating and vapor deposition, and a surface having an Au layer. Processing can be performed easily.

The photoelectron emitting material 78 is a plate material before being bent into a cylindrical shape, that is, a sheet shape, because the plate material before being bent into a cylindrical shape is subjected to surface treatment such as plating or vapor deposition. Therefore, the surface treatment such as plating and vapor deposition can be easily performed, and the workability thereof is good and can be easily performed.

Of course, the surface may be plated or vapor-deposited after being bent into a cylindrical shape. In that case, the bending or bending is performed after the surface is subjected to plating or vapor deposition after being bent into a cylindrical shape. Molds that often occur,
There is no fear that the surface of the photoelectron emitting material 78 subjected to the surface treatment by the jig will be damaged, and damage during bending can be prevented.

Further, the photoelectron emitting material 78 has a terminal connecting portion 8
Since 6 is integrally formed and the terminal 87 that conducts to the control circuit 70 is connected, it is not necessary to provide a terminal connecting portion as a separate component, and thus it can be formed at low cost.

In connection with the control circuit 70, since the negative ion generating section 80 is arranged between the control circuit 70 and the exhaust port 53, the wiring from the negative ion generating section 80 to the control circuit 70 is shortened. Therefore, the wiring work can be easily performed, and the negative ions 81 can be diffused and emitted into the entire room by being placed on the air flow.

The irradiation source 79 for irradiating the ultraviolet rays is connected to the control circuit 70, and the irradiation of the irradiation source 79 is turned ON-O.
Controls such as intermittent FF and varying the ultraviolet irradiation intensity of the irradiation source 79 are performed.
When the irradiation of the UV lamp is intermittently turned on and off, the total life of the ultraviolet lamp 82 which is the irradiation source 79 can be extended by turning on and off the ultraviolet lamp 82 which is the irradiation source 79. It is possible to adjust and control the excessive emission of the ions 81, and it is possible to generate negative ions close to the natural world.

Next, when the ultraviolet irradiation intensity of the irradiation source 79 is changed, the generation amount of negative ions 81 increases as the irradiation intensity of ultraviolet rays increases, and the generation amount of negative ions 81 decreases as the irradiation intensity decreases. Irradiation source 79
The generation amount of the negative ions 81 can be controlled by changing the ultraviolet irradiation intensity of the ultraviolet lamp 82, which is a temperature sensor, the use environment such as temperature and humidity, and the detection of the odor detection sensor 68 and the particle detection sensor 69. By changing the ultraviolet irradiation intensity of the irradiation source 79 according to the usage state such as the degree of contamination of the indoor air, the negative ions 81
It is possible to variably control the generation amount of the negative ions 81, and it is possible to generate the negative ions 81 close to the natural world.
