Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a negative ion generator.
[0002]
[Prior art]
Negative ions are said to be incorporated into the human body, resulting in tranquilizing effects, improving body constitution, metabolic effects, and various other effects in promoting health, as well as wall materials that cause sick house syndrome. It is said that it also has the effect of neutralizing the positive ions generated from.
[0003]
In recent years, such negative ions have attracted attention, and various negative ion generators for generating the negative ions have been provided.
[0004]
The negative ion generator has a discharge type that discharges oxygen in the air with negative electricity and combines it with a small amount of water to form negative ions, and then puts it in the wind to release negative ions. The so-called Leonard type, which focuses on the fact that when a water droplet splits in the air, the water droplet is positively charged, and the surrounding air is negatively charged, causing the ionization of air and the generation of negative ions. There is.
[0005]
The Leonard type is based on the phenomenon called the Leonard phenomenon that there are many negative ions around the waterfall etc., it is similar to the negative ions in nature, and it is more than the negative ions generated by the aforementioned discharge. It is said to have a long life and be human-friendly.
[0006]
As a Leonard type negative ion generator configured to generate such natural negative ions, there is one described in, for example, JP-A-2001-289470.
[0007]
This is because, in a processing chamber into which outside air can be introduced, the lower part of the rotating body, whose diameter increases upward, is immersed in water and rotated, so that a thin film of water is directed upward along the outer periphery of the rotating body. The mist atmosphere containing negative ions is formed by sequentially forming and scattering, and colliding the scattered water with a screen having a mesh arranged around the rotating body, and giving a negative charge to the outside air passing through the processing chamber. , The concentration of negative ions is increased.
[0008]
Further, it is stated that the screen having the mesh can be formed in a cylindrical shape surrounding a part of the rotating body, or can be configured to rotate together with the rotating body by being fixed to the rotating body.
[0009]
[Problems to be solved by the invention]
However, in the conventional Leonard-type minus-in generator described above, the centrifugal force of the rotating body causes water to impinge on the mesh and break it into extremely small water droplets. Was not possible.
[0010]
In other words, as described above, in the case of a screen having a mesh shape, only the water droplets are finely divided, and the water droplets are violently hit, and it is not possible to further reduce the size. .
[0011]
Therefore, it is difficult to fill the living space of the human body such as the room with the negative ions widely, and it is difficult to sufficiently incorporate the useful negative ions into the human body.
[0012]
In addition, negative ions generated by the Leonard type negative ion generator are called large ions, which have a long life but have a problem of low diffusion power, and it is difficult to fill the entire living space with negative ions. Problems remain.

That is, by rotating the substantially funnel-shaped water absorbing body, the water rises up the water absorbing groove formed on the outer peripheral surface of the water absorbing body due to wettability, and eventually scatters around due to centrifugal force, but scattered. Water droplets are struck by a large number of comb teeth forming small gaps and are finely divided.
[0022]
By this action, a large amount of fine water droplets are generated, and a large amount of negative ions in the air are also generated.
[0023]
In addition, since the comb teeth are formed at the periphery of the flange portion having the largest diameter among the water absorbing bodies, the peripheral speed is maximum, and the fine water droplets are scattered outward by the comb teeth at an accelerated rate.
[0024]
Therefore, a wall body can be provided around the water absorbing body.
[0025]
By providing such a wall, fine water droplets that have been hit and split by the comb teeth are accelerated and scattered around, and collide with the inner peripheral surface of the wall, so that the fine water droplets are further miniaturized, and negative ions are easily generated. State.
[0026]
As described above, according to the present embodiment, a larger amount of fine water droplets can be generated, and accordingly, a large amount of negative ions can be effectively generated.
[0027]
In addition, a reinforcing wall can be provided at the base end of the comb teeth, and by such a reinforcing wall, distortion of the comb teeth can be suppressed, and generation of noise can be particularly prevented when the water absorbing body rotates at high speed. .
[0028]
Further, it is preferable to form a step between the upper end of the water absorption groove and the inner peripheral surface of the flange portion.
[0029]
By providing such a stepped portion, the water rising from the water absorption groove is easily separated from the water absorbing body at this stepped portion, and is smoothly scattered by centrifugal force, and it is possible to generate a large amount of fine water droplets. It becomes.
[0030]
Further, a vibration isolator can be provided on the outer peripheral surface of the wall.
[0031]
As described above, the water absorber rotates at high speed to scatter water, and there is a concern that sound may be generated.However, by installing a vibration isolator, the effect of external noise can be minimized. Thus, the negative ion generator can be used at home without any problem.
[0032]
As described above, the negative ion generator according to the present embodiment is of a so-called Leonard type, and the generated negative ions are so-called large ions, are extremely large in mass, and have a long life. Yes, it is very human friendly because it is of the same nature as the negative ions that exist in the natural world, especially around waterfalls.
[0033]
By generating a large amount of high quality negative ions with a compact device and letting the human body ingest a sufficient amount, recovery from fatigue, mental stability, physical constitution improvement, blood purification, metabolism, resistance enhancement, autonomic nervous adjustment, gastrointestinal Various effects such as promotion of digestion can be achieved.
[0034]
Further, the above-mentioned negative ion generator may be provided with a discharge type negative ion source for generating negative ions by discharging, and both may be incorporated in the same housing.
[0035]
As the discharge-type negative ion source, a well-known configuration in which a surrounding electrode serving as a positive electrode is provided around a needle electrode serving as a negative electrode, and both electrodes are connected to a booster circuit can be employed.

It is explanatory drawing of the water-absorbing body which is the main structural element of the principal part.

However, in order to facilitate understanding, the upper cover case 31 is omitted in FIG. 1 and the peripheral wall portion 33 of the functional unit storage case 30 is omitted in FIG.
[0040]
(Leonard negative ion generator 1)
Here, the Leonard type negative ion generator 1 which is a main part of the present invention will be described in detail.
[0041]
As shown in FIGS. 1 and 2, the Leonard type negative ion generator 1 includes a fine water droplet generator 11 for generating fine water droplets, and sucks air from outside the housing 3 and sends the air to the fine water droplet generator 11. A fan unit 12 for diffusing fine water droplets generated by the fine water droplet generation unit 11 into air to form mixed air; and a centrifugal separation of the mixed air including fine water droplets to produce minus ionized ultrafine water droplets. And a centrifugal separation unit 13 that generates mixed air containing only
[0042]
The fine water droplet generator 11 and the centrifugal separator 13 are juxtaposed in the water tank 10 having an upper opening formed below the upper wall 34 of the housing 3. Reference numeral 35 denotes an intermediate wall connected to the lower end of the upper wall portion 34, and forms the water tank 10. W is stored water.
[0043]
In addition, the fine water droplet generating unit 11 has a substantially funnel-shaped water absorbing body 5 gradually expanding upward attached to a rotating shaft 15 protruding upward from the motor 14. A cylindrical portion 35a as a wall is provided at appropriate intervals so as to surround the water absorbing body 5.
[0044]
Further, as shown in FIGS. 1, 3 and 4, the water absorbing body 5 includes a lower end of a cylindrical portion 50 through which the rotating shaft 15 is inserted, and a lower end of a main body portion 51 gradually expanded upward. They are integrally connected and arranged so that the lower part of the whole is submerged in water. In addition, the taper θ of the outer peripheral surface of the main body 51 is preferably in a range of 60 ° <θ <75 °. In order to efficiently disperse water while avoiding a remarkable increase in diameter, in the present embodiment, θ is set to θ. It is set to 70 ° experimentally.
[0045]
In FIG. 2, reference numeral 15a denotes a motor shaft cover, which is formed integrally with the water tank 10. Reference numeral 52 denotes a connecting member for connecting the distal end portion of the rotary shaft 15 and the water absorbing body 5, and 53 denotes a bearing, which is provided via a seal member 54a. 54b is a packing, and 55 is a washer.
[0046]
A large number of water absorbing grooves 56 are formed in the outer peripheral surface of the main body 51 of the water absorbing body 5 in a vertical direction. When the water absorbing body 5 is rotated at a high speed by the motor 14, the draft portion of the stored water W is crawled due to wettability. As it rises, it moves so as to be sucked upward so as to be guided by the water absorbing groove 56. In this embodiment, the rotation speed of the water absorbing body 5 is set to about 1600 rpm.
[0047]
Further, a flange portion 57 is formed at an upper portion of the main body portion 51 of the water absorbing body 5, and a large number of comb teeth 58 are vertically provided on a peripheral edge of the flange portion 57 with a small gap 59 therebetween. ing.
[0048]
The individual comb teeth 58 alone have a radial length d of 5 mm, which is approximately １ ／ of the width D of the flange portion 57, and the length (height) L of the comb teeth 58 is It is 10 mm, which is about 1/10 of the total height. Such sizing can be determined experimentally.
[0049]
Since the comb teeth 58 are located at the position where the maximum diameter of the water absorbing body 5 is formed, the angular velocity at the time of rotation becomes maximum. Therefore, when the water absorbing body 5 is rotated and water is sucked up from the water absorbing groove 56 and scattered. In addition, the scattered water can be effectively bombarded and split into fine water droplets.
[0050]
In addition, since the comb teeth 58 have a predetermined width (5 mm) and have the maximum angular velocity as described above, they can hit fine water droplets and scatter at an accelerated outside of the water absorbing body 5, By making the minute water droplets collide with the inner peripheral wall of the cylindrical portion 35a at a furious speed, a larger amount of finer water droplets can be generated.
[0051]
As described above, by using the water absorber 5 according to the present embodiment, a large amount of fine water droplets can be generated, and a large amount of negative ions can be generated in the air.
[0052]
As shown in the figure, a reinforcing wall 57a integrally formed with the flange portion 57 is provided at the base end of the comb teeth 58. In the present embodiment, the length (height) L of the comb teeth 58 is set to １ ／ to prevent distortion of the comb teeth 58 during high-speed rotation as much as possible. Therefore, a vibration damping effect is generated by the reinforcing wall 57a, and noise at the time of high-speed rotation of the water absorbing body 5 is also prevented.
[0053]
Moreover, since the reinforcing wall 57a and the flange portion 57 are integrally formed in a substantially L-shape in cross section, the flange portion 57 also has a function as a reinforcing wall for the comb teeth 58, and FIG. As shown in the figure, the above-described vibration-proof effect and noise-preventing effect can be achieved by securing the effective area of the surface of the comb teeth 58 that hits the water droplets sufficiently, and by reinforcing the flange 57 in the horizontal direction and the reinforcing wall 57a in the vertical direction. It will definitely occur.
[0054]
Further, in order to more effectively prevent noise, as shown in FIG. 3, an anti-vibration material 7 is provided on the outer peripheral wall surface of the water tank 10.
[0055]
The vibration damping member 7 can minimize the generation of noise when the water absorber 5 rotates at a high speed, and the negative ion generator A can be suitably used at home or the like.
[0056]
Meanwhile, in the water absorbing body 5 according to the present embodiment, as shown in FIGS. 3 and 4, a step portion 6 is formed between the upper end of the water absorbing groove 56 and the inner peripheral surface of the flange portion 57.
[0057]
By providing such a stepped portion 6, the water rising from the water absorption groove 56 is easily separated from the main body 51 of the water absorbing body 5 at the stepped portion 6 and is scattered smoothly by centrifugal force. Therefore, it is possible to effectively generate a large amount of fine water droplets.
[0058]
Here, the other configuration of the Leonard type negative ion generating section 1 will be described. As shown in FIGS. 1 and 2, the fan section 12 is provided on one lower side of the housing 3 and has a fan case 12a. A sirocco fan 12b interlocked with a fan motor 12f is provided therein, and an ULPA filter 12c, a pre-filter 12d, and a filter holder 12e are provided therein.
[0059]
The base end of the duct 36 is connected to the fan case 12a, and the opening 36a at the front end of the duct 36 faces the upper part of the fine water droplet generator 11.
[0060]
Therefore, the wind generated by the fan unit 12 is introduced into the fine water droplet generation unit 11 through the flow path in the duct indicated by the arrow f in FIG. In FIG. 2, reference numeral 36b denotes a blower guide formed on the upper wall 34.
[0061]
Further, the centrifugal separation unit 13 separates fine water droplets having a large particle diameter from the mixed air containing a large number of divided fine water droplets sent by the air blow from the fan unit 12 from the fine water droplet generation unit 11 and only the very fine water droplets are separated. As shown in FIG. 1, a cylinder with a spiral streak communicating with the cylindrical portion 35 a surrounding the water absorbing body 5 in the water tank 10 and forming a spiral streak (not shown) therein as shown in FIG. It is composed of a part 35b. Then, it is possible to separate fine water droplets having a large particle diameter while rotating the mixed air sent from the fine water droplet generation unit 11. Reference numeral 34a denotes a guide cylinder which also serves as a water supply port protruding from the upper wall portion 34, and can supply water to the water tank 10 via the centrifugal separation section 13. In addition, when negative ions are generated, mixed air containing negative ions released from the spirally threaded cylindrical portion 35b can be guided to the outside of the apparatus.
[0062]
With the configuration described above, in the Leonard type negative ion generator 1 of the present embodiment, when the motor 14 is driven, the water absorber 5 formed in a substantially funnel shape rotates at high speed, and the water stored in the water tank 10 due to the wettability of the water. W rises in the water absorption groove 56 and is scattered by the centrifugal force during the ascent or effectively by the step portion 6, and the scattered water droplets are hit by a large number of comb teeth 58 forming the small gap 59 and finely divided. At the same time, the fine water droplets were smashed at high speed against the inner peripheral wall of the cylindrical portion 35a, and became finer fine water droplets. The water droplet and the air around it become negatively ionized, and a mixed air in which both ions are mixed is generated.
[0063]
The mixed air is sent to the centrifugal separation unit 13 where fine water droplets having a large particle diameter are separated and returned to the water tank 10 to become a mixed air containing a large amount of negative ions. As shown in (2), it is discharged from the upper part of the spirally threaded cylindrical portion 35b.
[0064]
It is to be noted that the mixed air containing the negative ions is finally discharged from the discharge port 41 formed in the upper cover case 31. As shown in FIG. A guide plate 41a is provided to guide the direction of discharge of the light in a substantially horizontal direction. Therefore, the negative ions from the Leonard type negative ion generator 1 in the present embodiment are emitted from the housing 3 slightly obliquely upward from a substantially horizontal direction.
[0065]
In FIG. 1, reference numeral 8 denotes a drainage tank communicating with a water tank 10, which is connected to a drainage port 13 a formed below the centrifugal separator 13 of the water tank 10 by a drainage hose 80.
[0066]
The drainage tank 10 is provided so as to be able to be taken out of the housing 3, and old stored water having passed a predetermined time is appropriately discarded before various bacteria and the like are generated.
[0067]
(Discharge type negative ion generator 2)
Next, the discharge type negative ion generator 2 will be described.
[0068]
As shown in FIG. 5, the discharge-type negative ion generator 2 has a peripheral electrode 22 that is a positive electrode disposed around a needle electrode 21 that is a negative electrode, and connects both electrodes 21 and 22 to a booster circuit 23. A well-known structure including the negative ion generator 2a is adopted. In the figure, 24 is an electrode cover formed in a funnel shape, 25 is an ion guide cylinder, 26 is a ventilation path, and 27 is a protective mesh.
[0069]
When a high voltage is applied between the needle electrode 21 and the surrounding electrode 22, plasma discharge occurs and negative ions are generated. In this case, the negative ions are called small ions, and a gas that is attracted to and combined with electrons. The number of molecules is about several to several tens, the diffusing power in the air is extremely large, and the molecules are generated in large quantities on a scale of 1 million / cc.
[0070]
The negative ion generator 2a is housed at the distal end side of the cylindrical portion 28 whose base end is connected and connected to the middle of the duct 36 described in the Leonard type negative ion generating portion 1, and is discharged to the distal end of the cylindrical portion 28. The outlet 42 is open upward (see FIGS. 1 and 2).
[0071]
That is, the wind flowing from the fan section 12 through the duct 36 flows into the cylindrical section 28, and the minus ions generated by the negative ion generator 2a are discharged upward from the discharge port 42 on the wind. In FIG. 2, reference numeral 34b denotes a circular hole through which the cylindrical portion 28 is inserted.
[0072]
Since the discharge port 42 and the discharge port 41 of the above-described Leonard type negative ion generator 1 are provided completely independently, the released negative ions do not interfere with each other and are released smoothly.
[0073]
According to the above configuration, when the present negative ion generator A is used, as shown in FIG. 6, the negative ion generator A is generated by the Leonard type negative ion generator 1 and discharged from the discharge port 41 in an obliquely upward direction which is almost horizontal. Negative ions, which are ions, are easily taken into the human body directly toward the human in the living space Q.
[0074]
On the other hand, the negative ions, which are small ions generated by the discharge-type negative ion generator 2 and emitted in large quantities vertically upward from the outlet 42, diffuse into the living space Q at high speed, and at this time, along the wall. 6 to quickly neutralize the positive ions on the wall surface, and form a negative ion barrier between the wall surface and the center of the living space Q as shown by the dashed line M in FIG. The environment in the interior can be kept good, and the onset of sick house syndrome or the like due to environmental hormones from wall materials or the like can be prevented.
[0075]
As described above, the present negative ion generator A can efficiently generate a large amount of large ions based on the Leonard effect, and at the same time, the generated negative ions are easily taken into the human body and released. It produces various effects such as recovery effect, mental stability effect, constitution improvement effect, blood purification effect, metabolism effect, resistance enhancement effect, autonomic nervous adjustment effect, gastrointestinal digestion promotion effect, etc. Since the positive ions generated from the wall material and the like can be neutralized with the negative ions of the small ions that are diffused and the indoor environment can be satisfactorily prepared, it is suitable for the living space Q where humans live.
[0076]
Next, a modified example of the water absorbing body 5 according to the present embodiment will be described with reference to FIGS. The same components as those in the above-described embodiment are denoted by the same reference numerals.
[0077]
In FIG. 7, the reinforcing wall 57a is omitted from the configuration of the above-described embodiment, and the comb teeth 58 are formed to hang directly from the flange portion 57. Then, the length L is formed shorter by the amount of no reinforcement.
[0078]
According to such a configuration, water droplets can be hit and split using the entire comb teeth 58, and can be scattered at an accelerated rate from between the small gaps 59. Can be hit reliably.
[0079]
8 is different from the configuration of the above-described embodiment in that the shape of the step portion 6 is different. The upper end portion 56a of the water absorption groove 56 is formed in a curved shape so as to smoothly continue with the step portion 6. Is formed.
[0080]
According to this configuration, the water that has risen from the water absorption groove 56 is smoothly guided to the stepped portion 6 and quickly scatters from the main body 51 due to the centrifugal force when the water absorbing body 5 rotates. In this modified example, the stepped portion 6 is positioned further below the lower end of the reinforcing wall 57a so that the scattered water droplets can be reliably reached the comb teeth 58 and hit, thereby generating fine water droplets. Easy to do. In this modification, the inside of the corner portion where the flange portion 57 and the reinforcing wall 57a intersect is curved to form a structure in which water conductivity is further improved.
[0081]
FIG. 9 shows a configuration in which the step portion 6 is omitted from the configuration of the above-described embodiment, and the upper end of the water absorption groove 56 directly abuts against the back surface of the flange portion 57. Since the step portion 6 does not need to be formed, manufacturing is facilitated.
[0082]
The one shown in FIG. 10 eliminates the step portion 6 and forms the water absorption groove 56 halfway without extending to the flange portion 57, as if at the upper end portion 56 a of the closed water absorption groove 56. 6 has the same function as that of FIG.
[0083]
Even with such a configuration, the water that has risen from the water absorption groove 56 is effectively separated from the main body 51 at the upper end 56a of the water absorption groove 56 and scatters. Also in this case, since the step portion 6 does not need to be formed, the manufacturing becomes easy.
[0084]
