Description

  The present invention relates to an ion generation element for generating ions, an ion generation device, a method for manufacturing the ion generation device, and an ion blower.

Conventionally, a phenomenon called corona discharge is generally known (see Patent Document 1). Corona discharge occurs when a high voltage is applied between a needle-like discharge electrode and a plate-like induction electrode, causing dielectric breakdown in the air near the tip of the discharge electrode, thereby causing a gap between the discharge electrode and the induction electrode. This is a phenomenon in which current flows.
Patent Document 1 discloses an ion generator using corona discharge. The discharge electrode and the induction electrode provided in this ion generator are fixed to the support substrate by soldering.

JP 2008-53000 A

  If the creepage distance between the fixed position of the discharge electrode and the fixed position of the induction electrode on the support substrate is too short, the electric field around the tip of the discharge electrode will be weakened due to foreign matter adhering to the discharge electrode or exhaustion of the discharge electrode. There is a risk of abnormal discharge. This abnormal discharge has a problem of unnecessarily increasing the discharge sound associated with corona discharge.

  The present invention has been made in view of such circumstances, and its main purpose is to extend the creeping distance with a simple configuration by forming a slit between the discharge electrode and the induction electrode in the support substrate. Another object of the present invention is to provide an ion generating element, an ion generating device, an ion generating device manufacturing method, and an ion blower that can suppress the occurrence of abnormal discharge.

  The ion generating element according to the present invention is characterized in that the insulating coating portion has a plate shape in which a through hole through which the leg portion is inserted is formed.

  The ion generating element according to the present invention is characterized in that the slit is formed at a position closer to a covering position of the one surface by the insulating covering portion than a supporting position of the discharge electrode.

  In the ion generating apparatus according to the present invention, the ion generating element is the ion generating element according to the present invention, and is made of the same material as the insulating sealing portion and the insulating protruding portion, and the one surface and the insulating coating It is characterized by comprising an insulating bonding part for bonding the part.

  The method of manufacturing an ion generator according to the present invention includes: storing the ion generating element according to the present invention in a storage case; and insulating sealing on the other surface between the other surface opposite to the one surface and the inner surface of the storage case. A method of manufacturing an ion generating apparatus for forming the insulating sealing portion by filling and curing a mold material for stopping, wherein a part of the mold material injected between the other surface and the inner surface is The insulating protrusion is formed by curing the molding material in a state where the slit is passed through and protrudes from the one surface.

  In the method for manufacturing an ion generating apparatus according to the present invention, the ion generating element is the ion generating element according to the present invention, and another part of the molding material flows through the slit along the one surface. The insulating bonding portion is formed by curing the mold material in a state of being diffused and entering between the one surface and the insulating coating portion.

  An ion blower according to the present invention includes the ion generator according to the present invention and a blower, and the air blown by the blower flows through a space in which ions generated by the ion generation element of the ion generator float. It is made to do so.

In this invention, an ion generating element is provided with the support substrate in which the acicular discharge electrode, the induction electrode which has a plate-shaped part and a leg part, and the slit are formed.
A through hole is formed in the plate-like portion of the induction electrode, and the tip of the discharge electrode is inserted into the through-hole of the plate-like portion. For this reason, when a high voltage is applied between the discharge electrode and the induction electrode, a corona discharge occurs between the tip of the discharge electrode and the opening edge of the through hole of the induction electrode. Occur.

The distal end portion of the discharge electrode and the plate-like portion of the induction electrode are arranged on one surface side of the support substrate. The leg part of the induction electrode protrudes from the plate-like part. The discharge electrode and the leg portion of the induction electrode are each supported by a support substrate.
The slit of the support substrate passes through the support substrate, and the discharge electrode support position (hereinafter referred to as discharge support position) on the support substrate and the support position of the induction electrode leg (hereinafter referred to as induction support position). It is formed between. The longitudinal direction of the slit intersects the juxtaposed direction between the discharge support position and the induction support position.
The slit of the support substrate is for extending the creeping distance between the discharge support position and the induction support position.

The ion generating element according to the present invention is provided in an ion generating apparatus. The ion generator according to the present invention further includes a housing case, an insulating sealing portion, and an insulating protrusion.
The storage case stores the ion generating element. The insulating sealing portion insulates and seals the other surface of the support substrate included in the ion generating element. For this purpose, the insulating sealing portion is filled between the other surface of the support substrate and the inner surface of the housing case.

The insulating protrusion protrudes from one surface of the support substrate. The insulating protrusion is provided integrally with the insulating sealing portion through a slit formed in the support substrate. Furthermore, since the insulating protrusion is formed along the slit, the insulating protrusion is positioned between the discharge support position and the induction support position on the support substrate, and the longitudinal direction of the insulation protrusion includes the discharge support position and the induction support position. It intersects with the juxtaposed direction.
Therefore, the creeping distance between the discharge support position and the induction support position is extended by an amount corresponding to the protrusion of the insulating protrusion as compared with the case where the insulating protrusion does not exist. In addition, both the ion generator provided with the insulating protrusion and the ion generating element provided with the slit for providing the insulating protrusion have a simple configuration.

The manufacturing method of the ion generator which concerns on this invention is for manufacturing the ion generator which concerns on this invention.
For example, the manufacturer prepares an ion generating element according to the present invention, a housing case, and a molding material for insulating sealing on the other surface of the support substrate. It is desirable that this mold material has necessary and sufficient fluidity.
Next, the manufacturer houses the ion generating element in the housing case.

  Furthermore, the manufacturer injects and fills the molding material between the other surface of the support substrate and the inner surface of the housing case. At this time, a part of the molding material injected between the other surface of the support substrate and the inner surface of the housing case flows through the slit of the support substrate and protrudes from one surface of the support substrate. If the mold material is cured in this state, the mold material filled between the other surface of the support substrate and the inner surface of the housing case becomes an insulating sealing portion, and flows through the slit of the support substrate to face one surface of the support substrate. The mold material that protrudes further becomes an insulating protrusion.

  The process of forming an insulating sealing portion by filling a mold material between the other surface of the support substrate and the inner surface of the housing case (hereinafter referred to as an insulating sealing process) itself is a manufacturing process of a conventional ion generator. include. In the present invention, since the slit is formed in the support substrate, the insulating sealing portion and the insulating protruding portion are simultaneously formed by the same insulating sealing process as the conventional insulating sealing process. In other words, the insulating sealing process in the present invention also serves as a process of forming the insulating protrusion.

  The ion blower according to the present invention includes the ion generator according to the present invention and a blower. For this reason, compared with the ion blower provided with the conventional ion generator and the air blower, the creeping distance between a discharge support position and an induction | guidance | derivation support position is long.

In the present invention, the ion generating element further includes an insulating coating portion that covers one surface of the support substrate.
The insulating coating portion is disposed between the guide support position and the slit. Therefore, the creepage distance between the discharge support position and the induction support position is equal to the thickness of the insulating coating portion (that is, the length of the insulating coating portion in the thickness direction of the support substrate) than when the insulating coating portion does not exist. Has also been extended.

  In the present invention, the insulating coating portion provided in the ion generating element has a plate shape and is formed with a through hole. The leg portion of the induction electrode is inserted through the through hole of the insulating coating portion. Therefore, it is easy to attach the insulating coating, and the insulating coating is prevented from being unnecessarily dropped from the support substrate.

  In the present invention, in the support substrate of the ion generating element, the discharge support position, the slit formation position, the coating position on one surface of the support substrate by the insulating coating portion, and the induction support position are arranged in this order. The slit is formed at a position closer to the covering position on one surface of the supporting substrate by the insulating covering portion than the discharge supporting position.

An ion generating apparatus including such an ion generating element includes an insulating bonding portion that bonds one surface of the support substrate and the insulating coating portion. This insulating bonding portion is made of the same material as the insulating sealing portion and the insulating protruding portion.
Since one surface of the support substrate and the insulating coating portion are bonded to each other by the insulating bonding portion, it is possible to suppress useless gaps between the one surface of the support substrate and the insulating coating portion. If such a gap is generated, the insulation coating portion may not be able to contribute to the extension of the creepage distance between the discharge support position and the induction support position.

In order to manufacture such an ion generating device, for example, a manufacturer prepares the above-described ion generating element, a storage case, and a molding material.
Next, the manufacturer houses the ion generating element in the housing case.
Furthermore, the manufacturer injects and fills the molding material between the other surface of the support substrate and the inner surface of the housing case. At this time, a part of the molding material injected between the other surface of the support substrate and the inner surface of the housing case flows through the slit of the support substrate and protrudes from one surface of the support substrate. Further, another part of the injected molding material flows through the slit of the support substrate, diffuses along one surface of the support substrate, and enters between the one surface of the support substrate and the insulating coating portion.

If the mold material is cured in this state, the mold material filled between the other surface of the support substrate and the inner surface of the housing case becomes an insulating sealing portion, and flows through the slit of the support substrate to face one surface of the support substrate. The mold material that protrudes further becomes an insulating protruding portion, and the mold material that has entered between the one surface of the support substrate and the insulating coating portion becomes an insulating adhesive portion.
That is, the insulating sealing process according to the present invention also serves as a process of forming the insulating bonding portion. Therefore, it is not necessary to separately bond one surface of the support substrate and the insulating coating portion.

In the case of using the ion generating element, the ion generating device, the ion generating device manufacturing method, and the ion blower of the present invention, the creeping distance between the discharge support position and the induction support position on the support substrate is extended with a simple configuration. Can do. Therefore, a sufficiently long creepage distance can be easily secured.
Therefore, the occurrence of abnormal discharge due to the creepage distance being too short can be easily suppressed. As a result, an unnecessary increase in discharge sound due to abnormal discharge can be easily suppressed.

  Moreover, the ion generating element according to the present invention can be easily obtained by forming a slit in the support substrate provided in the conventional ion generating element. In addition, in the manufacturing process of the ion generator according to the present invention, and further in the manufacturing process of the ion blower according to the present invention, it is not necessary to provide a process of forming the insulating protrusions separately from the insulating sealing process. Therefore, manufacture of the ion generating element of this invention, an ion generator, and an ion air blower is easy.

  Hereinafter, the present invention will be described in detail with reference to the drawings illustrating embodiments thereof.

Embodiment 1.
FIG. 1 is a side sectional view schematically showing an internal configuration of an ion blower 1 according to Embodiment 1 of the present invention. Hereinafter, the left side of FIG. 1 is referred to as the front side of the ion blower 1. Moreover, the right side of FIG. 1 is called the back side of the ion blower 1.
The ion blower 1 includes a vertical rectangular parallelepiped casing 10, and the casing 10 is erected on the floor F in the room.
A suction port 111 is opened on the back surface 10 a of the housing 10. An air outlet 112 is opened in the top surface 10 b of the housing 10. A ventilation path 11 that connects the suction port 111 and the air outlet 112 is provided inside the housing 10. A blower 3 is built in the ventilation path 11.

  The blower 3 uses a sirocco fan and includes a fan 31 and a fan motor 32. Air blowing by the blower 3 is performed by the fan motor 32 rotating the fan 31. At this time, air flows through the inside of the ventilation path 11. Further, indoor air is sucked into the ventilation path 11 through the suction port 111. Furthermore, the air inside the ventilation path 11 blows out into the room through the air outlet 112.

Between the suction port 111 and the blower 3, the ventilation path 11 is closed, and a deodorizing filter 121 and a dust collection filter 122 are arranged in this order from the windward side to the leeward side.
The deodorizing filter 121 is formed by attaching activated carbon to a nonwoven fabric, for example. The odor of air passing through the deodorizing filter 121 is removed by being adsorbed by the activated carbon.
The dust collection filter 122 is a so-called HEPA (High Efficiency Particulate Air) filter. The dust collection filter 122 adsorbs dust such as fine floating dust and sand dust in the air by static electricity.
The suction port 111 is closed by a net-like prefilter (not shown).

  The air sucked through the suction port 111 first passes through the prefilter. At this time, coarse dust contained in the air is collected. The air that has passed through the prefilter is then deodorized by passing through the deodorizing filter 121. Further, the deodorized air passes through the dust collection filter 122. At this time, fine dust contained in the air is collected. As a result, the ion blower 1 functions as an air purifier having a dust collecting and deodorizing function.

  The ion blower 1 may have a configuration in which a humidification unit is disposed between the dust collection filter 122 and the blower 3. The humidification unit has a water tank, a disk-shaped humidification filter, and a rotation mechanism. The humidification filter sucks up the water in the aquarium. The rotating mechanism promotes water absorption by the humidifying filter by rotating the humidifying filter. In the ion blower 1 having such a configuration, the air that has passed through the dust collection filter 122 is further humidified by passing through the humidification filter. In this case, the ion blower 1 also functions as a humidifier.

In the vicinity of the air outlet 112, the ion generator 2 is arranged.
The ion generator 2 generates positive ions and negative ions (hereinafter referred to as positive and negative ions). For this purpose, the ion generator 2 includes an ion generating element 4.
Positive and negative ions generated by the ion generating element 4 float inside the ventilation path 11. Positive and negative ions floating inside the ventilation path 11 are released into the room together with the air blown into the room through the air outlet 112.

  Positive and negative ions released into the room kill or inactivate fungi, viruses, allergens, and the like floating in the room air. Positive and negative ions decompose substances that cause malodor (for example, organic compounds such as acetaldehyde). As a result, the ion blower 1 functions as an air cleaner having a function of decomposing and deodorizing pollutants by ions.

Next, the structure of the ion generator 2 which concerns on Embodiment 1 of this invention is explained in full detail.
FIG. 2 is a block diagram showing the configuration of the electrical system of the ion generator 2.
FIG. 3 is a cross-sectional view showing the internal configuration of the ion generator 2. Hereinafter, the left side (and right side) of FIG. 3 is referred to as the left side (and right side) of the ion generator 2.
FIG. 4 is a partially enlarged view of FIG. FIG. 4 shows the vicinity of the left insulating protrusion 28 (described later).
5 and 6 are a perspective view and an exploded perspective view showing the external appearance of the ion generating element 4. The cross section of the ion generating element 4 shown in FIG. 3 is a cross section taken along line VV in FIG.

As shown in FIG. 2, in addition to the ion generating element 4, the ion generating device 2 includes a housing case 21, a power input connector 22, a driving circuit 23, a high voltage generating circuit 24, a positive high voltage generating circuit 25, and a negative high voltage generating unit. A circuit 26 is further provided. Hereinafter, the power input connector 22, the drive circuit 23, the high voltage generation circuit 24, the positive high voltage generation circuit 25, and the negative high voltage generation circuit 26 are collectively referred to as an electric circuit unit 20.
Further, as shown in FIGS. 3 and 4, the ion generator 2 further includes an insulating sealing portion 27, two insulating protrusions 28 and 28, and insulating bonding portions 29 and 29. Illustration of the electric circuit unit 20 in FIGS. 3 and 4 is omitted.
The housing case 21, the insulation sealing part 27, each insulation protrusion part 28, and each insulation adhesion part 29 have insulation.

First, the configuration of the ion generating element 4 will be described with reference to FIGS.
The ion generating element 4 includes two needle-like discharge electrodes 41, 41, an induction electrode 42, a support substrate 43, and two rectangular plate-like insulating coating portions 44, 44.
Each discharge electrode 41 and induction electrode 42 have conductivity. Each insulation coating portion 44 has an insulating property.

The support substrate 43 has a rectangular shape.
Hereinafter, the longitudinal direction of the support substrate 43 is referred to as the left-right direction of the ion generating element 4. The left-right direction of the ion generating element 4 in the state provided in the ion generating device 2 and the left-right direction of the ion generating device 2 are the same direction. The ion generating element 4 is generally symmetrical.
The short direction of the support substrate 43 is referred to as the front-rear direction of the ion generating element 4.
Furthermore, the direction orthogonal to the support substrate 43 is referred to as the vertical direction of the ion generating element 4.
Furthermore, one surface of the support substrate 43 is referred to as an upper surface, and the other surface opposite to the upper surface is referred to as a lower surface.

  The support substrate 43 is formed with two first through holes 431 and 431, second through holes 432 and 432, and slits 433 and 433. Regarding the left half (or right half) of the ion generating element 4, these are arranged in the left-right direction in the order of the second through-hole 432, the slit 433, and the first through-hole 431 from the left side (or right side) of the support substrate 43. It is installed. With respect to the left half (or right half) of the ion generating element 4, the separation distance in the left-right direction between the right end portion of the second through hole 432 and the left end portion of the slit 433 is the right end portion of the slit 433 and the first through hole 431. It is shorter than the left-right separation distance from the left end of the.

Each discharge electrode 41 is made of metal. One end side of the discharge electrode 41 has a sharp shape, and the other end side has a non-sharp shape. Hereinafter, the sharp end portion of the discharge electrode 41 is referred to as the distal end portion of the discharge electrode 41, and the non-sharp end portion of the discharge electrode 41 is referred to as the proximal end portion of the discharge electrode 41.
Each discharge electrode 41 is supported by a support substrate 43. For this purpose, the central portion in the longitudinal direction of the discharge electrode 41 is fitted in the first through hole 431 of the support substrate 43. At this time, the distal end portion of the discharge electrode 41 protrudes toward the upper surface side of the support substrate 43, and the proximal end portion of the discharge electrode 41 protrudes toward the lower surface side of the support substrate 43.

  Each discharge electrode 41 is fixed to the support substrate 43 by solder (not shown) from the lower surface side of the support substrate 43. At this time, the base end side of the discharge electrode 41 is electrically connected to a wiring pattern or a lead wire (not shown) via solder.

A through hole 441 is formed in the center portion of each insulating coating portion 44 in the front-rear and left-right directions.
The insulating coating 44 covers the periphery of the second through-hole 432 on the upper surface of the support substrate 43 (and thus the periphery of a leg 46 described later). More specifically, the insulating coating 44 covers at least the opening edge of the slit 433 to the opening edge of the second through hole 432. However, the insulating coating 44 does not partially or completely block the slit 433.

The induction electrode 42 has a plate-like portion 45 and two leg portions 46, 46 integrally. The induction electrode 42 is formed by bending a single metal flat plate having a predetermined shape.
Two circular through holes 421 and 421 are formed in the plate-like portion 45. The through holes 421 and 421 are separated from each other by an appropriate length in the left-right direction.
The distal end portion of the discharge electrode 41 is inserted into each through hole 421. At this time, the tip of the discharge electrode 41 is located at the center in the depth direction and the center in the radial direction of the through hole 421. The inner surface of the through hole 421 and the discharge electrode 41 are separated from each other by an appropriate length so that the discharge electrode 41 does not contact the plate-like portion 45. That is, the front end portion of the discharge electrode 41 and the opening edge portion of the through hole 421 are arranged to face each other in a plane direction through a space having air.

One leg portion 46 is provided on each of the left and right end portions of the plate-like portion 45. The legs 46, 46 are parallel and face each other.
Each leg portion 46 has a plate shape orthogonal to the plate-like portion 45. Moreover, the leg part 46 has the base end side leg part 461 and the front end side leg part 462 integrally. The length of the proximal leg 461 in the front-rear direction is longer than the length of the distal leg 462 in the front-rear direction. That is, the leg part 46 has an inverted convex shape when viewed from the side. The distal leg 462 can enter either the through hole 441 of the insulating coating 44 or the second through hole 432 of the support substrate 43, but the proximal leg 461 can enter either of them. I can't.

  Each of the leg portions 46 and 46 is supported by the support substrate 43. For this purpose, the leg portions 46 and 46 are fitted in the second through holes 432 and 432 of the support substrate 43. More specifically, the distal end side leg portion 462 of each leg portion 46 is inserted through the through hole 441 of the insulating coating portion 44 and is fitted into the second through hole 432. At this time, the plate-like portion 45 and the base end side leg portion 461 are arranged on the upper surface side of the support substrate 43. The separation distance of the plate-like portion 45 from the upper surface of the support substrate 43 is equal to the sum of the vertical length of the base end side leg portion 461 and the protruding amount of the insulating coating portion 44 described later. The lower end portion of the distal leg portion 462 protrudes to the lower surface side of the support substrate 43.

  Each leg portion 46 is fixed to the support substrate 43 by solder (not shown) from the lower surface side of the support substrate 43. At this time, the lower end side of the distal leg portion 462 is electrically connected to a wiring pattern or a lead wire (not shown) via solder.

As described above, the formation position of the first through hole 431 is the support position of the discharge electrode 41. The formation position of the second through hole 432 is a support position of the leg portion 46. Therefore, it can be said that the slit 433 is formed between the support position of the discharge electrode 41 and the support position of the leg portion 46.
Further, it can be said that the slit 433 is formed at a position closer to the covering position of the upper surface of the supporting substrate 43 by the insulating covering portion 44 than the supporting position of the discharge electrode 41.

The slit 433 has a linear shape whose longitudinal direction intersects (orthogonally in this embodiment) the juxtaposed direction of the support position of the discharge electrode 41 and the support position of the leg portion 46. That is, the slit 433 is formed in the front-rear direction. The length of the slit 433 in the longitudinal direction is equal to the length of the insulating coating portion 44 in the front-rear direction.
The slit 433 passes through the support substrate 43.
The opening width of the slit 433 will be described later.

Next, the assembly procedure of the ion generating element 4 will be described.
The manufacturer first prepares two discharge electrodes 41, 41, an induction electrode 42, a support substrate 43, and two insulating coating portions 44, 44.
Next, the manufacturer places the induction electrode 42 and the insulating coating portions 44, 44 on the upper surface side of the support substrate 43.

  Next, the manufacturer attaches the leg portions 46 and 46 of the induction electrode 42 to the support substrate 43 together with the insulating coating portions 44 and 44. More specifically, the manufacturer inserts the leg-side legs 462 and 462 of the legs 46 and 46 from above into the through holes 441 and 441 of the insulating coating parts 44 and 44, and then the second of the support substrate 43. The through holes 432 and 432 are inserted from above. At this time, the lower end portions of the base end side leg portions 461 and 461 are in contact with the insulating coating portions 44 and 44, and further, the insulating coating portions 44 and 44 are interposed between the base end side leg portions 461 and 461 and the support substrate 43. If sandwiched, the induction electrode 42 and the insulation coating portions 44 and 44 are easily positioned with respect to the support substrate 43.

Further, the manufacturer inserts the discharge electrodes 41 and 41 into the first through holes 431 and 431 of the support substrate 43 from the lower surface side of the support substrate 43. At this time, each discharge electrode 41 is easily positioned in the front-rear and left-right directions with respect to the support substrate 43.
Then, the discharge electrodes 41 and 41 and the leg portions 46 and 46 are soldered to the support substrate 43, respectively.

Next, the configuration of the ion generator 2 will be described with reference to FIGS.
The housing case 21 includes a lid portion having a top surface 21a and a bottomed cylindrical case body portion having a bottom surface 21b. However, the lid part and the case body part are not distinguished in the figure. Each of the top surface 21a and the bottom surface 21b has a rectangular shape. The longitudinal directions of the top surface 21 a and the bottom surface 21 b are along the left-right direction of the ion generator 2.
Two circular through holes 211 and 211 are formed on the top surface 21 a of the housing case 21. The separation distance between the through holes 211 and 211 and the diameter of each through hole 211 correspond to the separation distance between the through holes 421 and 421 of the induction electrode 42 and the diameter of each through hole 421.

The ion generating element 4 is accommodated on the top surface 21 a side of the accommodation case 21. In this case, the four sides of the support substrate 43 and the inner surface of the housing case 21 are in close contact. Further, the upper surface (and the lower surface) of the support substrate 43 provided in the ion generating element 4 and the top surface 21a (and the bottom surface 21b) of the housing case 21 face each other.
The electrical circuit unit 20 is accommodated on the bottom surface 21 b side of the accommodation case 21.

An insulating sealing portion 27 that insulates and seals at least the lower surface of the support substrate 43 is filled between the lower surface of the support substrate 43 and the inner surface of the housing case 21. The electric circuit portion 20 except the power input connector 22 is buried in the insulating sealing portion 27.
A part of the power input connector 22 is buried in the insulating sealing portion 27, and the remaining portion is exposed to the outside of the housing case 21 from the bottom surface 21 b of the housing case 21. The ion generator 2 is supplied with power for generating positive and negative ions via the power input connector 22. The power input connector 22 may be configured to be exposed to the outside of the housing case 21 from an appropriate peripheral surface of the housing case 21 instead of the bottom surface 21b.

The housing case 21 is attached to the inside of the housing 10 of the ion blower 1. More specifically, the housing case 21 is attached to the inside of the housing 10 so that the inside of the housing case 21 and the ventilation path 11 of the ion blower 1 communicate with each other through the through holes 211 and 211. At this time, the power supply unit (not shown) included in the ion blower 1 and the power input connector 22 are electrically connected.
The power supply unit of the ion blower 1 is supplied with power from, for example, a commercial power supply. The ion generator 2 is supplied with power from the power supply unit of the ion blower 1 via the power input connector 22.

Here, the electric circuit unit 20 will be described.
The power input connector 22 of the electric circuit unit 20 is electrically connected to the input end of the drive circuit 23.
The output terminal of the drive circuit 23 is electrically connected to the input terminal of the high voltage generation circuit 24.
The high voltage generation circuit 24 has two output terminals. The first output terminal of the high voltage generation circuit 24 is electrically connected to the input terminal of the positive high voltage generation circuit 25, and the second output terminal is electrically connected to the input terminal of the negative high voltage generation circuit 26. The high voltage generation circuit 24 is also connected to the induction electrode 42 (more specifically, the lower end side of the distal end leg portion 462).

The output terminal of the positive high voltage generation circuit 25 is electrically connected to the base end side of one discharge electrode 41, and the output terminal of the negative high voltage generation circuit 26 is electrically connected to the base end side of the other discharge electrode 41.
The drive circuit 23 supplied with power through the power input connector 22 drives the high voltage generation circuit 24. At this time, the high voltage generation circuit 24 boosts the voltage of the supplied power. As a result, a positive high voltage is applied to one of the discharge electrodes 41 via the positive high voltage generation circuit 25 with respect to the induction electrode 42. Also, a negative high voltage is applied to the induction electrode 42 via the negative high voltage generation circuit 26 to the other discharge electrode 41.

When corona discharge occurs between the tip of the discharge electrode 41 to which a positive high voltage is applied and the opening edge of the through hole 421 of the induction electrode 42, positive ions are generated near the tip of the discharge electrode 41. . Similarly, when corona discharge occurs between the tip of the discharge electrode 41 to which a negative high voltage is applied and the opening edge of the through hole 421 of the induction electrode 42, negative ions are generated near the tip of the discharge electrode 41. Will occur.
The positive ions in this embodiment are hydrogen ions (H ⁺ ) Is a cluster ion accompanied by a plurality of water molecules, and H ⁺ It is expressed as (H ₂ O) _m (m is a natural number). The negative ions in this embodiment are cluster ions in which a plurality of water molecules are attached around oxygen ions (O ₂ ⁻ ), and are expressed as O ₂ ⁻ (H ₂ O) _n (n is a natural number). . Further, in this embodiment, H ⁺ which is a positive ion. (H ₂ O) _m and negative ions O ₂ ⁻ (H ₂ O) _n are generated in substantially the same amount.

When the blower 3 of the ion blower 1 blows air, the air inside the housing case 21 is sucked into the ventilation path 11. At this time, positive and negative ions generated in the ion generating element 4 together with the sucked air are released to the ventilation path 11 and float inside the ventilation path 11. As a result, as described above, positive and negative ions are released into the room together with the air that blows out into the room through the air outlet 112.
Then, positive and negative ions surround airborne fungi and viruses in the indoor air and adhere to these surfaces to cause a chemical reaction. Airborne fungi and viruses in the air are sterilized or inactivated by the action of the active species hydroxyl radical (.OH) generated by this chemical reaction.

Next, the insulating protrusions 28 and 28 and the insulating bonding portions 29 and 29 will be described with reference to FIGS. 3 and 4. Hereinafter, the left half of the ion generator 2 will be described as an example, but the same applies to the right half of the ion generator 2.
The insulating protrusion 28 is made of the same material as the insulating sealing portion 27. Further, the insulating protruding portion 28 is provided integrally with the insulating sealing portion 27 through the slit 433.
Further, the insulating protrusion 28 is formed along the slit 433. Furthermore, the insulating protrusion 28 protrudes from the upper surface of the support substrate 43. At this time, the left side portion of the insulating protrusion 28 is in close contact with the right end surface of the insulating coating portion 44.

  An insulating adhesive portion 29 is provided between the lower surface of the insulating coating portion 44 and the upper surface of the support substrate 43. The insulating bonding portion 29 bonds the lower surface of the insulating coating portion 44 and the upper surface of the support substrate 43. For this reason, the lower surface of the insulating coating portion 44 and the upper surface of the support substrate 43 are sealed by the insulating bonding portion 29. The insulating bonding portion 29 is made of the same material as the insulating sealing portion 27 and the insulating protruding portion 28. The insulating bonding portion 29 is provided integrally with the insulating sealing portion 27 and the insulating protrusion 28.

Next, the creeping distance between the discharge electrode 41 and the induction electrode 42 in the support substrate 43 will be described.
In the conventional ion generator, the insulating protrusion 28, the insulating adhesive 29, the slit 433, and the insulating coating 44 are not present. Therefore, the creeping distance between the discharge electrode 41 and the induction electrode 42 regarding the conventional ion generator is the distance L1 shown in FIG.

  For simplicity, here, the protrusion amount of the insulating protrusion 28 based on the upper surface of the support substrate 43 (hereinafter simply referred to as the protrusion amount of the insulating protrusion 28) and the upper surface of the insulating coating 44 from the upper surface of the support substrate 43 The distance up to (that is, the sum of the thickness of the insulating coating portion 44 and the thickness of the insulating bonding portion 29, hereinafter referred to as the protruding amount of the insulating coating portion 44) will be described as the distance L4. The distance L1 is equal to the sum of the distance L2 from the discharge electrode 41 to the slit 433 and the distance L3 from the slit 433 to the induction electrode 42.

The creepage distance related to the ion generator 2 of the present embodiment is equal to the sum of the distance L2, the distance L4, and the distance L3 (that is, the sum of the distance L1 and the distance L4). From this, it can be seen that the creepage distance related to the ion generator 2 of the present embodiment is extended by the distance L4 than the creepage distance related to the conventional ion generator. That is, the insulating protrusion 28 and the insulating coating 44 can improve the insulation between the discharge electrode 41 and the leg 46 (and thus the induction electrode 42).
When the protruding amount of the insulating protruding portion 28 is longer than the protruding amount of the insulating coating portion 44, the creepage distance is further extended.
Even if the protruding amount of the insulating protruding portion 28 is shorter than the protruding amount of the insulating covering portion 44, the creepage distance is equal to the sum of the distance L2, the distance L3, and the distance L4.

Next, the assembly procedure of the ion generator 2 will be described.
First, the manufacturer prepares the ion generating element 4, each part of the electric circuit unit 20, the housing case 21, and the molding material. The molding material to be prepared here is generally silicon rubber or epoxy, but is not particularly limited. However, the molding material must have a suitable fluidity before curing and be a material that can insulate high voltage electricity after curing.

Next, the manufacturer electrically connects each part of the electric circuit part 20 to the ion generating element 4. Then, the manufacturer houses the electric circuit unit 20 in the case main body of the housing case 21. Further, the manufacturer houses the ion generating element 4 in the case main body portion of the housing case 21.
Next, the manufacturer performs an insulating sealing process in which the insulating sealing portion 27 is formed by filling a molding material between the lower surface of the support substrate 43 and the inner surface of the housing case 21.

The manufacturer in the insulating sealing process injects a molding material into a space surrounded by the lower surface of the support substrate 43 and the inner surface of the case main body of the housing case 21. At this time, the injected molding material fills the space between the lower surface of the support substrate 43 and the inner surface of the housing case 21.
The manufacturer continues to inject the molding material even after the molding material is filled between the lower surface of the support substrate 43 and the inner surface of the housing case 21. Then, the mold material flows through the slits 433 and 443 and overflows to the upper surface side of the support substrate 43.
A part of the overflowing mold material comes into close contact with the right end surface of the insulating coating portion 44 and rises like a bank due to surface tension. That is, a part of the overflowing mold material protrudes from the upper surface of the support substrate 43.

Another part of the overflowing mold material enters between the upper surface of the support substrate 43 and the lower surface of the insulating coating portion 44 by capillary action.
After the injection of the molding material, the manufacturer attaches a lid to the case main body of the housing case 21.
In this state, the manufacturer cures the mold material. As a result, the mold material filled between the lower surface of the support substrate 43 and the inner surface of the housing case 21 becomes the insulating sealing portion 27. Further, the mold material that rises along the right end surface of the insulating coating portion 44 becomes the wall-shaped insulating protrusion 28. Further, the mold material that has entered between the upper surface of the support substrate 43 and the lower surface of the insulating coating portion 44 becomes a layered insulating adhesive portion 29.

As a result, the insulating sealing portion 27, the insulating protrusion 28, and the insulating bonding portion 29 are formed simultaneously in the insulating sealing process.
Note that the slit 433 is not limited to a linear shape, and may be a curved shape.
In addition, a plurality of slits shorter than the slits 433 may be arranged in a broken line in the support substrate 43 instead of the single linear slit 433. Even in such a configuration, if the separation distance between the plurality of slits is sufficiently short, the mold materials raised from the adjacent slits are naturally joined together, so that the insulating protruding portion similar to the insulating protruding portion 28 Is formed.

Here, the opening width of the slit 433 will be described.
The opening width of the slit 433 needs to be appropriately set according to the fluidity of the molding material in consideration of the curing time of the molding material, the protruding amount of the insulating protrusion 28, and the like. For this purpose, it is desirable to previously obtain the relationship between the width of the opening of the slit 433 and the fluidity of the molding material, the curing time, the amount of protrusion of the insulating protrusion 28, and the like by experiments.

Next, abnormal discharge will be described.
When an abnormal state occurs in which foreign matter adheres to the discharge electrode 41 or the discharge electrode 41 is consumed, a discharge start voltage between the tip of the discharge electrode 41 and the opening edge of the through hole 421 of the induction electrode 42 is generated. Rises. In such a case, the discharge near the tip of the discharge electrode 41 may not occur.
At this time, if moisture or dust adheres to the upper surface of the support substrate 43, there is a risk that discharge will occur outside the vicinity of the tip of the discharge electrode 41 in the conventional ion generator. This discharge is abnormal discharge. Specifically, it is an abnormal discharge through the upper surface of the support substrate 43 (for example, an abnormal discharge between the proximal end side of the discharge electrode 41 and the leg portion 46 of the induction electrode 42).

  However, in the ion generator 2 according to the present embodiment, the discharge between the proximal end side of the discharge electrode 41 and the leg portion 46 of the induction electrode 42 is performed by the extent that the creeping distance is extended as compared with the conventional ion generator. The starting voltage increases. Therefore, if the ion generator 2 is used, generation | occurrence | production of abnormal discharge can be suppressed. As a result, it is possible to solve the problem that the discharge sound accompanying the corona discharge is unnecessarily increased due to the abnormal discharge.

  By the way, it is necessary to increase the protruding amount of the insulating protruding portion 28 and the protruding amount of the insulating coating portion 44 as the amount of moisture or dust attached to the upper surface of the support substrate 43 increases. Therefore, the protruding amount of the insulating protruding portion 28 and the protruding amount of the insulating coating portion 44 are determined by the attachment of moisture, dust, or the like to the support substrate 43 in the general usage state of the ion generator 2 (and thus the ion blower 1). It is desirable to set it based on the result of the experiment which measures quantity.

  The number of discharge electrodes 41 may be one or three or more. In this case, the number of through holes 421 in the induction electrode 42 may be equal to or greater than the number of discharge electrodes 41. In addition, the ion generating element 4 is not limited to the configuration that generates positive and negative ions, and may be configured to generate either positive ions or negative ions.

Embodiment 2. FIG.
FIG. 7 is a partially enlarged cross-sectional view showing the internal configuration of the ion generator 2 according to Embodiment 2 of the present invention. FIG. 7 corresponds to FIG. 4 of the first embodiment.
Below, the ion generator 2 which concerns on Embodiment 1 is called 1st ion generator 2, and the ion generator 2 which concerns on this Embodiment is called 2nd ion generator 2. FIG.
First, the difference between the first and second ion generators 2 and 2 will be described. Other parts corresponding to those in the first embodiment are denoted by the same reference numerals, and description thereof is omitted.

Also in the second ion generating device 2, the slit 433 is formed at a position closer to the covering position of the upper surface of the supporting substrate 43 by the insulating covering portion 44 than the supporting position of the discharge electrode 41. However, the opening left end portion of the slit 433 and the right end surface of the insulating coating portion 44 are separated by an appropriate length.
The distance L1 is the sum of the distance L5 from the discharge electrode 41 to the slit 433, the distance L6 from the slit 433 to the right end surface of the insulating coating portion 44, and the distance L7 from the right end surface of the insulating coating portion 44 to the induction electrode 42. be equivalent to.

  The creepage distance related to the second ion generator 2 is the sum of the distance L5, twice the distance L4, the distance L6, the distance L4, and the distance L7 (that is, the sum of the distance L1 and the distance L4 three times). )be equivalent to. From this, it can be seen that the creepage distance related to the second ion generator 2 is further extended by twice the distance L4 than the creepage distance related to the first ion generator 2. In other words, the second ion generator 2 is more advantageous than the first ion generator 2 with respect to the creepage distance.

On the other hand, the first ion generator 2 is more advantageous than the second ion generator 2 in the insulating sealing process. In other words, the first ion generator 2 is easier to manufacture than the second ion generator 2. The reason for this will be described below.
In the case of the first ion generator 2, when the molding material overflows to the upper surface side of the support substrate 43, a part of the overflowing molding material is brought into close contact with the right end surface of the insulating coating portion 44 and is caused by surface tension. Easy and full of excitement.
In addition, another part of the overflowing mold material easily and sufficiently enters between the upper surface of the support substrate 43 and the lower surface of the insulating coating portion 44 by capillary action.

  On the other hand, in the case of the second ion generating device 2, when the molding material overflows to the upper surface side of the support substrate 43, a part of the overflowing molding material is its own surface regardless of the insulating coating portion 44. It tries to rise due to tension. At this time, if the flowability of the mold material is too high, the length of the mold material rises short. As a result, the protruding amount of the insulating coating portion 44 is insufficient.

  In addition, another part of the overflowing mold material diffuses to the upper surface of the support substrate 43 and then enters between the upper surface of the support substrate 43 and the lower surface of the insulating coating portion 44 by capillary action. At this time, if the molding material does not have sufficient fluidity, the molding material cannot sufficiently enter between the upper surface of the support substrate 43 and the lower surface of the insulating coating portion 44. As a result, the insulating bonding portion 29 is not formed, and there is a possibility that an unnecessary gap is generated between the upper surface of the support substrate 43 and the lower surface of the insulating coating portion 44.

Insufficient amount of protrusion of the insulating coating portion 44 and useless air gap between the upper surface of the support substrate 43 and the lower surface of the insulating coating portion 44 are caused between the discharge electrode 41 and the leg portion 46 (and thus the induction electrode 42). This is a problem because it reduces insulation.
From the above, when manufacturing the second ion generating device 2, setting the fluidity of the molding material appropriately means that the fluidity of the molding material is reduced when manufacturing the first ion generating device 2. It turns out that it is more difficult to set properly.
In addition, the manufacturer may form the insulating bonding portion 29 by injecting an adhesive between the upper surface of the support substrate 43 and the lower surface of the insulating coating portion 44 separately from the insulating sealing process.

Embodiment 3. FIG.
FIG. 8 is an exploded perspective view showing the configuration of the ion generating element 4 according to Embodiment 3 of the present invention. FIG. 8 corresponds to FIG. 6 of the first embodiment.
The ion generating element 4 in the embodiment of the present invention has substantially the same configuration as the ion generating element 4 in the first embodiment. However, slits 434 and 434 are formed instead of the slits 433 and 433 in the first embodiment. Other parts corresponding to those in the first embodiment are denoted by the same reference numerals, and description thereof is omitted.

Each slit 433 in the first embodiment is linear in plan view. On the other hand, the slit 434 in the embodiment of the present invention has a U-shape in plan view.
Hereinafter, the left half of the ion generating element 4 will be described as an example, but the same applies to the right half of the ion generating element 4.
The slit 434 includes a first slit 43a and two second slits 43b and 43b.

The first slit 43a corresponds to the slit 433 in the first embodiment.
The second slits 43b and 43b are formed in a direction orthogonal to the first slit 43a so as to protrude leftward from both front and rear ends of the first slit 43a.
The insulating coating 44 covers at least the opening edge of the slit 434 to the opening edge of the second through hole 432. However, the insulating coating portion 44 does not block the slit 434 partially or entirely.

  In the case of the ion generating apparatus 2 including the ion generating element 4 as described above, an insulating protrusion having a U-shape in plan view is formed by the mold material overflowing from the slit 434. Since this insulating protrusion surrounds the discharge electrode 41 side of the leg 46 in the support substrate 43 in a U-shape, the discharge electrode 41 and the leg are compared with the case where the linear insulating protrusion 28 is formed. Insulation with 46 (and thus the induction electrode 42) can be further improved.

Embodiment 4 FIG.
FIG. 9 is a cross-sectional view showing the internal configuration of the ion generator 2 according to Embodiment 4 of the present invention. FIG. 10 is an exploded perspective view showing the configuration of the ion generating element 4 according to Embodiment 4 of the present invention. 9 and 10 correspond to FIGS. 3 and 6 of the first embodiment.

  The ion generating element 4 in the embodiment of the present invention has substantially the same configuration as the ion generating element 4 in the first embodiment except that the insulating coating portions 44 and 44 are not provided. Therefore, the ion generator 2 in the embodiment of the present invention has substantially the same configuration as that of the ion generator 2 in the first embodiment, except that the insulating bonding portions 29 and 29 are not provided. Other parts corresponding to those in the first embodiment are denoted by the same reference numerals, and description thereof is omitted.

In the present embodiment, with respect to the left half (or right half) of the ion generating element 4, the separation distance in the left-right direction between the second through hole 432 and the slit 433, and between the slit 433 and the first through hole 431. There is no notable restriction on the magnitude relationship with the left-right separation distance. This is because it is not necessary to form the insulating bonding portions 29 and 29.
Each leg 46 of the induction electrode 42 integrally includes a proximal leg 463 and a distal leg 464 similar to the proximal leg 461 and the distal leg 462 in the first embodiment.

However, the length in the vertical direction of the distal end side leg portion 464 is shorter than the distal end side leg portion 462 by the amount of protrusion of the insulating coating portion 44. This is because it is sufficient that the front end side leg portion 464 has a length enough to protrude to the lower side of the support substrate 43 through the second through hole 432 of the support substrate 43.
On the other hand, the length in the vertical direction of the base end side leg portion 463 is longer than the length of the base end side leg portion 461 by the amount of protrusion of the insulating coating portion 44. This is because the lower end portion of the base end side leg portion 463 is in contact with the upper surface of the support substrate 43, but in the case of the base end side leg portion 461, the insulating coating portion 44 and the insulating adhesive portion 29 are connected to the base end side leg. This is because it functions as a spacer between the lower end of the portion 461 and the upper surface of the support substrate 43.

Next, the creeping distance between the discharge electrode 41 and the induction electrode 42 in the support substrate 43 will be described.
The creepage distance in the present embodiment is extended by twice the protruding amount of the insulating protruding portion 28 from the distance L1 shown in FIG. That is, the insulating protrusion 28 can improve the insulation between the discharge electrode 41 and the leg 46 (and thus the induction electrode 42).

The ion generating device 2 and the ion generating element 4 according to the present embodiment have a simple configuration as compared with the first ion generating device 2 and the ion generating element 4 according to the first embodiment. Moreover, the ion generator 2 of the present embodiment is more advantageous than the first ion generator 2 by the distance L4 with respect to the creepage distance.
However, in the ion generator 2 of the embodiment, when the fluidity of the mold material is too high, the length of the mold material swell is insufficient, and as a result, the protruding amount of the insulating coating portion 44 is insufficient. This is more disadvantageous than the first ion generator 2.
In addition, the ion generating element 4 of the present embodiment has more metal material necessary for forming each leg portion 46 than the ion generating element 4 of the first embodiment.

The embodiment disclosed this time is to be considered as illustrative in all points and not restrictive. The scope of the present invention is not intended to include the above-described meanings, but is intended to include meanings equivalent to the claims and all modifications within the scope of the claims.
Moreover, as long as the effect of the present invention is obtained, the ion blower 1, the ion generator 2, or the ion generator 4 may include components that are not disclosed in the first to fourth embodiments.
