[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an ion generator and an air conditioner using the same, and more particularly, to an ion generator which generates positive and negative ions alternately and uses the same. The present invention relates to an air control device.

[0003]

2. Description of the Related Art Generally, in a closed room such as an office or a conference room with low ventilation, if there are many people in the room, air pollutants such as carbon dioxide, cigarette smoke and dust emitted by respiration. As a result, negative ions having the effect of relaxing humans decrease from the air. In particular, a large amount of negative ions are lost due to cigarette smoke, and may be reduced to about 1/2 to 1/5 of the normal amount. Therefore, various ion generators have been commercially available for replenishing negative ions in the air, but all of them generate only negative ions by a DC high voltage method. An air purifier that generates positive ions and negative ions alternately has been put to practical use.

[0004]

A conventional ion generator that generates only negative ions can supply negative ions to the air, but cannot actively remove airborne bacteria in the air. However, it has been put to practical use by the applicant, but there has been a problem that an ion generator that generates positive ions and negative ions alternately while suppressing generation of ozone cannot generate each of them in a well-balanced manner.

The present invention has been made in view of such a conventional problem, and efficiently generates positive ions and negative ions in a well-balanced manner, and supplies floating ions to the air while supplying the amount of positive ions and negative ions to the air. It is to provide an indoor air control device such as an air conditioner that can be removed.

[0006]

According to the present invention, there is provided a dielectric, and a first electrode and a second electrode opposed to each other with the dielectric interposed therebetween, and an AC voltage is applied between the first and second electrodes. And an ion generator that generates positive ions and negative ions alternately by applying a voltage, wherein one end of one electrode is bent toward the dielectric.

[0007] The relationship between the first electrode and the second electrode is such that when the second electrode is projected onto the first electrode, the end of the first electrode is included in the projected view of the second electrode. I do.

Further, the dielectric is cylindrical, and the first
The electrode is a cylindrical plate electrode, and the second electrode is a cylindrical mesh electrode.

Further, the inner diameter of the second electrode is made smaller than the outer diameter of the dielectric, and the second electrode is inserted into the dielectric so as to push out and expand to form the space.

Further, the present invention is to mount the ion generator having each of the above-mentioned configurations in a room air control device.

[0011]

BEST MODE FOR CARRYING OUT THE INVENTION The present inventors have conducted intensive studies on not only the supply of negative ions into the air but also the removal of airborne bacteria in the air. If positive and negative ions are generated by applying an AC voltage between a first electrode (hereinafter referred to as an inner electrode) and a second electrode (hereinafter referred to as an outer electrode), the air does not harm the human body. It has been found that airborne bacteria can be killed.

[0012] Ion generation apparatus of the present invention, by applying a high-frequency alternating voltage between the inner electrode and the outer electrode, and H ⁺ (H ₂ O) _n as positive ions, O as negative ions ₂ ^- (H ₂ O) _m alternately, and these react chemically on the surface of the bacterium to form hydrogen peroxide (H
₂ O ₂ ) and / or hydroxyl radical (.OH)
It removes airborne bacteria in the air.

The amount of ions generated by the ion generator tends to increase when the applied AC voltage is increased, and the amount of generated positive ions and negative ions tends to increase. When the amount of ions generated increases, it is effective for sterilization. However, the amount of ozone generated at the same time increases at the same time. Since ozone has a risk of harming human health, it is necessary to minimize the amount of ozone generated.

Therefore, a major feature of the ion generator of the present invention is that a mesh electrode is used as an outer electrode and a plate electrode is used as an inner electrode.
The axial length of the electrode when formed into a cylinder is that the mesh electrode of the outer electrode is longer than the plate electrode of the inner electrode.
According to such a configuration, the generation amount of the positive ion and the negative ion is stabilized, the respective ions can be efficiently generated with good balance, and the generation amount of ozone does not increase.

Hereinafter, the ion generator of the present invention will be described with reference to the drawings. FIG. 1 is a sectional view showing one embodiment of the ion generator of the present invention. The ion generator 1 shown in FIG. 1 includes a dielectric 2, an inner electrode 3 disposed in close contact with the inner peripheral surface of the dielectric 2, and an outer electrode disposed in close contact with the outer peripheral surface of the dielectric 2. 4 and a pair of plug members 5 and 6 fitted to both ends of the dielectric 2, and a lead wire 7 is inserted into the dielectric 2 through a hole 5 b formed at the center of the plug 5. Connected to electrode 3.

On the other hand, a lead wire 8 is also connected to the outer electrode 4, and an AC voltage power supply (not shown) is connected through the lead wires 7 and 8.
, An AC voltage is applied to the inner electrode 3 or the outer electrode 4. An example of the voltage generated from the AC voltage power supply has a peak value in a half wave of about 2.1 kV and a frequency of 20 kV.
There is a bactericidal effect when the frequency is set to kHz.

Preferably, this frequency is 10 kHz or more. When the frequency is 10 kHz or less, the user may feel noise because the frequency corresponds to a high sensitivity portion in the human audible sound range.

As the dielectric 2, for example, a glass tube having an outer diameter of 10 mm is used. The material used for the dielectric 2 is not limited to this, and any material that is generally considered to have an insulating property, such as a resin, may be used. The shape thereof is also not particularly limited as long as the first electrode and the second electrode are arranged so as to face each other, such as a flat plate, and may be appropriately determined based on the shape or structure of the device to be mounted. Electrode shape, size, distance between electrodes (dielectric thickness)
And the applied voltage and frequency have correlations with the amount of generated ions, respectively, so that it is necessary to find and design conditions excellent in the sterilizing effect each time by checking the amount of generated positive and negative ions.

The case where the dielectric 2 has a cylindrical shape will be described below. When the dielectric 2 has a cylindrical shape, for example, when the thickness is constant, the larger the outer diameter is, the larger the capacitance of the dielectric is. However, the larger the capacitance of the dielectric is, the more easily ions are generated. This has been found experimentally. Therefore, in consideration of increasing the amount of generated ions, it can be said that it is better to increase the outer diameter of the dielectric,
At the same time, there arises a problem that the amount of generated ozone increases.
Therefore, it is necessary to increase the amount of generated ions while suppressing the increase in the amount of generated ozone.

The inner electrode 3 is also called a high-voltage electrode. In this embodiment, the inner electrode 3 is SUS304 or SUS316.
And is connected to an AC voltage power supply via a lead wire 7.

The outer electrode 4 is called a ground electrode, is a mesh electrode using a wire mesh made of stainless steel wire made of SUS316 or SUS304, and is used as an installation electrode. The mesh spacing is preferably about 30 meshes (the mesh is a unit and indicates the number of holes per inch).

Next, the inner electrode 3 of the plate electrode will be described in more detail. In a plate-like state before the inner electrode 3 is processed into a cylindrical shape, a shape obtained by combining obtuse angles and acute angles in which all angles are not 90 degrees, for example, a trapezoidal shape WXYZ as shown in FIG.
It is formed by punching by blanking press or the like. Roll processing is performed so that the parallel sides (WX and ZY) are parallel to the cylinder axis to form a cylinder. The outer diameter of the cylindrical inner electrode 3 is slightly larger than the inner diameter of the dielectric 2. Here, the angles W and X are obtuse angles, and the angles Y and Z are acute angles. In this manner, the vertices formed at an acute angle (Y and Z in FIG. 2A) have a shape in which two vertices Y and Z protrude outward from the side WX of the inner electrode 3.

The reason why the ion generating device is formed in such a shape is that the vertexes Y and Z, which are portions protruding outward, are the portions which are most likely to be discharged when an AC voltage is applied. Variations between the devices when they are manufactured can be reduced, and the yield of the ion generator can be improved.

When the inner electrode 3 is mounted on the dielectric 2, a force is applied in the tangential direction of the plate-like inner electrode 3, which is rolled into a cylindrical shape, so that the cylinder is rounded, so to speak. Outer diameter d of the inner electrode 3 larger than the inner diameter (D)
Is applied in the direction toward the axis of the cylinder to make the diameter (D-α) smaller than the inner diameter of the dielectric 2, and the inner electrode 3 is inserted into the dielectric 2. After the insertion, the applied force is released, and the inner electrode 3 is brought into close contact with the inner peripheral surface of the dielectric 2 by a force for returning to the original state. Thus, the inner electrode 3 is fixed to the dielectric 2.

In order to obtain a stable discharge state with such an electrode configuration, it is desirable that the adhesion between the inner electrode 3 and the inner surface of the dielectric 2 be higher. When the adhesion between the inner electrode 3 and the dielectric 2 is poor, the distance between the inner electrode 3 and the outer electrode 4 is not substantially constant, and the amount of ions generated when an AC voltage is applied between the electrodes is reduced. May not be stable. When the variation in the amount of generated ions in such a case was determined by experiment, in a configuration in which the inner electrode 3 and the outer electrode 4 were simply opposed to each other without performing the processing as in the present invention, the positive ion was 0.1 mm. It has been confirmed that there is a problem that only an amount of generation of about 1 to 180,000 ions / cc and about 0.3 to 180,000 ions / cc of negative ions can be obtained, and furthermore, there is a large variation in ion generation ability among the apparatuses. I have.

Therefore, in order to prevent the above-mentioned variation, when the inner electrode 3 and the inner electrode 3 are formed in a cylindrical shape, approximately 1/2 to 1/4 of the circumference in the circumferential direction overlaps with the overlapping portion. They are formed so as to overlap each other. By forming in this way, a sufficient degree of adhesion can be obtained,
The amount of generated ions is stabilized. Further, at the same time, the number of overlapping portions is not too large, and easiness of processing is secured.

Next, the configuration of the outer electrode 4 will be described in detail. As described above, a mesh-like stainless material is used for the outer electrode 4. A reticulated stainless steel material is formed in a substantially rectangular flat shape. At this time, it is more preferable to spot weld the four corners in a rectangular shape because the wire mesh can be prevented from fraying. Next,
By performing roll processing, one side (corresponding to the long side in FIGS. 3 and 4) facing one side of the rectangle and several millimeters (approximately 3
(May be on the order of millimeters) and a portion thereof is spot-welded to form a cylinder. When formed in this way, the opposite sides of the rectangle having a right-angled relationship with the one side of the above-described rectangle when formed in a planar shape form both ends of the cylindrical electrode when formed in a cylindrical shape. .

The part to be spot-welded is as follows:
Taking into account the subsequent processing of both ends, the central portion in the axial direction of the overlapping portion of the cylinder is spot-welded.
Then, both ends are formed so as to be perpendicular to the cylindrical axis by a predetermined length, and further, curled to form an end 4.
a is formed and welded so as to be double over the entire circumference. At this time, the inner diameter of the manufactured outer electrode 4 is slightly smaller than the outer diameter of the dielectric 2. Thus, the second electrode has a structure in which a space that does not come into contact with the dielectric is provided near the bent end of the second electrode.

Then, the outer electrode 4 is press-fitted to the outside of the dielectric 2 and mounted at a predetermined position. As a result, the end 4a of the outer electrode 4 closely adheres to the dielectric 2, and a space A is slightly formed between the outer electrode 4 and the dielectric 2 at the other end of the curled portion. Thereafter, the outer electrode 4 is fixed to the dielectric 2 by locking several points in the axial direction with a fastening material having elasticity from the outside. Thus, the outer electrode 4 is brought into close contact with the dielectric 2.

In addition to the method of curling the end portion, FIG.
As shown in (a), a square or rectangular end may be bent inward L to form an L portion 4b. The angle of the L-bending process may be any angle as long as the end of the end of the outer electrode 4 when formed into a cylindrical shape by such processing can be brought into close contact with the dielectric 2 over the entire circumference. Even if the bent portion of the L portion is arc-shaped, the same operation and effect can be obtained as long as the end of the end portion is in contact with the dielectric. Then, if necessary, the four corners are spot-welded to prevent fraying of the wire mesh, and then rolled into a cylindrical shape to form a cylindrical shape.

At this time, the inner diameter of the manufactured outer electrode 4 is made slightly smaller than the outer diameter of the dielectric 2. Then, the outer electrode 4 is pressed into the outside of the dielectric 2 and stopped at a predetermined position.
As a result, the L portion 4b at the end of the outer electrode 4 closely adheres to the dielectric 2, and the L portion 4b is inserted into the dielectric 2 as shown in FIG. There is a slight space B between them. After that, the outer electrode 4 is brought into close contact with the dielectric 2 by fixing several places in the axial direction by the locking member 9.

The axial length of the inner electrode 3 when formed in a cylindrical shape is longer than the axial length of the outer electrode 4, and both electrodes are mounted on the dielectric 2. In this state, the end of the outer electrode 4 is located on the axially central side (that is, the other end) over the entire circumference than the end of the inner electrode 2, and the midpoint in the axial direction of both electrodes is substantially the same. They are formed so as to face each other. When formed in this manner, the positional relationship between the first electrode and the second electrode is such that the end of the first electrode is included in the projected view of the second electrode when the second electrode is projected onto the first electrode. Can be arranged. A specific example of the deviation between the end of the inner electrode 3 and the end of the outer electrode 4 at this time is about 0.5 mm to 1 mm.

As described above, after the inner electrode 3 is formed on the dielectric and the outer electrode 4 is formed, an electrode section for generating ions of the ion generator of the present invention is formed.

With such a configuration, the apex of the end of the inner electrode 3 (the apex Y and the apex Z in FIG. 2A) is located between the end of the outer electrode which is in close contact with the dielectric 2. It is possible to discharge stably. This is because the end portion is point-shaped on the inner electrode 3 to which a voltage is applied, whereas the outer electrode 4 is line-shaped on the outer electrode 4 and is in contact with the dielectric 2. Therefore, it is considered that the discharge is stabilized.

When the flat plate is rolled into a cylindrical shape, the shape of the top of the inner electrode 3 protruding from the end and the relationship between the first electrode and the second electrode are as follows. By projecting the end of the first electrode in the projection of the second electrode when projected onto the first electrode, more positive and negative ions are generated more stably, and the amount of both ions is reduced. It is possible to generate a well-designed amount of ions.

The reason why the outer electrode 4 is grounded and used as a ground electrode is that there is no danger of electric shock even if the user touches the ion generator. The reason is that it is possible to concentrate the electric field by forming the net shape, thereby reducing the voltage applied between the electrodes.

Further, the reason why the inner electrode 3 is formed into a plate shape is that the plate shape is more likely to be in close contact with the cylindrical dielectric 2 so as to make the distance between the electrodes substantially constant. Furthermore, even if the arrangement position is slightly shifted, the shape is less likely to be affected by the position shift if it is planar.

As described above, in the embodiment in which the end portion of the outer electrode 4 is curled, the end portion is bent toward the dielectric side, and the front end portion is brought into contact with the dielectric material, and the number is 400,000 / cc.
An ion generation amount of 600,000 ions / cc can be obtained with a reproducibility of 80% with respect to the total number of prepared devices.

Further, as described above, in the embodiment in which the end portion of the outer electrode 4 is formed into an L-shape and the end portion is bent toward the dielectric side, and the tip end is brought into contact with the dielectric, the number is 400,000. cc
An ion generation amount of up to 600,000 ions / cc can be obtained with a reproducibility of about 100% with respect to the total number of prepared devices.

Further, a configuration in which the end portion of the outer electrode 4 is bent toward the dielectric side and the tip end abuts on the dielectric material is described as follows.
In this case, the discharge state between the electrodes is more stable than when not provided at any one of the ends, and furthermore, the discharge state is provided at any one of the ends of the outer electrode 4. In this case, the state of discharge between the electrodes is more stable than when either one is provided.

In the above embodiment, the case where the dielectric 2 is cylindrical has been described.
When the shape and the positional relationship of the end portions are set to be the same, the same operation and effect can be obtained even when both electrodes are opposed to the flat dielectric.

The plug members 5 and 6 are put on both ends of the electrode portion formed as described above to ensure the insulating properties to the sides. The plug members 5 and 6 have a columnar shape, and are formed on their end surfaces with peripheral grooves 5a and 6a into which the ends of the dielectric 2 are fitted. A hole for passing a lead wire for supplying electricity to the inner electrode 3 is provided near the center of the plug members 5 and 6, and a part of the hole is formed so as to provide a thin film.

This thin film is easily broken when the lead wire 7 is passed. By penetrating the thin film, the insulation between the inner electrode 3 to which a voltage is applied and the outside is improved, and the thin film is formed. Thus, dust and the like can be prevented from entering the inner electrode 3.

The peripheral grooves 5a, 5a,
The width of 6a is desirably slightly smaller than the thickness of the dielectric 2 from the viewpoint of strongly fitting the plug members 5 and 6 to the dielectric 2.

Further, the plug members 5 and 6 may be made of an insulating material. However, since the plug members 5 and 6 can be easily fitted to the side ends of the dielectric 2 and can easily seal the dielectric 2, they can be made of rubber or the like. Elastic members are preferred. Among the elastic members, EPDM is more preferable because it has durability against ozone which may be generated in the ion generator.

The lead wires 7 and 8 connected to the inner electrode 3 and the outer electrode 4 are not particularly limited, and conventionally known ones can be used. However, a stainless steel wire is made of polyfluoride because of its excellent ozone resistance. Those coated with an ethylene fluoride resin are preferred.

The attachment of the lead wire 7 to the inner electrode 3 is performed by spot welding when the electrode is flat or after the roll processing, but it is related to the plate thickness. On the other hand, at the time of roll processing, it is difficult to perform roll processing and insertion into a glass tube after processing if the sheet thickness increases, but in the present embodiment, the sheet thickness is 0.08 mm.

It is desirable that the inner electrode 3 sandwiching the dielectric 2 and the outer electrode 4 do not shift. If the positions of the inner electrode 3 and the outer electrode 4 are misaligned, loss of electric capacity occurs when a voltage is applied to the electrodes. Here, the “position shift” means an axial shift.

According to the experimental results, the electric capacity may be lost by about 35 to 10% due to the displacement of the inner electrode 3 and the outer electrode 4. For this reason, in the ion generator, after the outer electrode of the mesh electrode is inserted into the glass tube, positioning is performed with a jig, and as shown in FIG. Fix several places in the axial direction, including the end of. This can prevent the axial displacement of the outer electrode.

Further, since the inner electrode 3 has an apex at the end of the inner electrode 3 hooked on the inner surface of the glass tube, the position of the inner electrode 3 and the outer electrode 4 is shifted as compared with a shape having no apex. It is unlikely to occur.

The ion generator 1 of FIG. 1 can be assembled, for example, as follows. The inner electrode 3 to which the lead wire 7 has been welded in advance is inserted into a predetermined position inside the dielectric 2 by a positioning jig. Then, the plug member 5 is fitted to one side end of the dielectric 2 while the free end of the lead wire 7 is inserted into the hole 5 b of the plug member 5. Next, the outer electrode 4 to which the lead wire 8 has been welded in advance is attached to the outside of the dielectric 2, and the end of the inner electrode 3 is slightly smaller than the end of the outer electrode 4 by a jig as shown in FIG. (About 0.5 to 1 mm), and the left and right ends of the outer electrode 4 are fixed by the elastic locking member 9, and a plug member is attached to the other side end of the dielectric 2. 6 is fitted.

When a voltage is applied to the inner electrode 3 formed as described above, the suitable amount of ions to be sterilized is 400,000 to 600,000 positive ions and 40 to 60,000 minor ions. It is possible to provide an ion generator capable of stably generating an ion amount of 10,000 / cc.

The operation will be described below. During the cooling operation, the high-temperature heat exchange medium condensed from the compressor 73 of the outdoor unit 71 is sent to the outdoor heat exchanger 72 of the outdoor unit 71. In the outdoor heat exchanger 72, the heat of the heat exchange medium is taken by the outdoor fan 75, and the heat exchange medium is cooled. The heat exchange medium passes through the expansion valve 74 and passes through the indoor unit 31.
