The belt-like auxiliary electrode 22 is disposed in the axial direction in which the handle 28 extends and is opposed to the opening position of the ion emission port 24, but has a length substantially equal to or longer than the arrangement range in the ion emission port 24. It is preferable to be disposed on both sides in the width direction across the ion emission port 24.

  Further, as illustrated in FIG. 11, the case body 10 includes a main body case 26 in which a heating surface and an ion emission port 24 are simultaneously provided on the lower surface side, and a handle 28 extending from the side surface of the main body case 26.

  In this case, it is preferable that the heating surface 152 is formed in a band shape in the axial direction in which the handle 28 extends, and the ion emission ports 24 are provided on both sides in the width direction across the heating surface 152.

  The case body 10 itself is formed of a conductive member such as a metal, or a metal screw for fixing an internal circuit component to the case body 10 or a case coupling part is necessary for the configuration. If the conductive member has a structure in which at least a part of the conductive member is exposed to the outside, the conductive member can be used as the auxiliary electrode 22.

  Here, as shown in FIG. 4, the discharging means 12 is a low voltage by intermittently supplying a DC voltage supplied from a battery 136 built in the case body 10 or a pulsating voltage Vb formed by rectifying the commercial AC voltage Va. Is discharged to the input side of the step-up transformer 76, and a high-voltage pulse voltage is taken out from the output side of the step-up transformer 76, and the high-voltage pulse voltage is integrated to discharge the negative-polarity high voltage Vd. Discharge is continuously performed by making it possible to apply to the electrode 16 at all times.

  The negative ions 112 generated by the discharge means 12 can be released to the outside of the case body 10 by natural convection. However, the blower means 30 is further provided inside the case body 10 to force the negative ions 112. In particular, it can be discharged outside the case body 10.

  Further, the discharging means 12 may further include a switching means 15, and in conjunction with the switching operation of the switching means 15, the driving timing of the discharging means 12 and the effective timing of the auxiliary electrode 22 can be regulated.

  As described above, the present invention includes the auxiliary electrode 22 that is exposed at the peripheral surface position of the case body 10 and has the substantially same potential as the ground line 18 inside the case body 10, thereby substantially reducing the area of the counter electrode 20. In addition, since the replenishment area of electrons increases, negative ions 112 can be generated efficiently.

  Further, the case body 10 is composed of the main body case 26 and the handle 28, and the auxiliary electrode 22 is provided in the handle 28 portion, so that the contact between the auxiliary electrode 22 and the human body during use of the instrument is reliably maintained, and the human body is Since it becomes a part of the auxiliary electrode 22 and the area of the counter electrode 20 further increases, the generation of negative ions can be further accelerated or increased.

This is effectively exhibited in combination with the action of removing excess ions by the auxiliary electrode 22.

  Further, at that time, the ion discharge port 24 is configured to face the outside of the case body 10 or the rib 154 is provided to prevent direct contact between the ion flow 124 and the auxiliary electrode 22, and more ions than necessary. Can be prevented from being removed.

  Further, a low voltage pulse voltage Vc is caused to flow to the input side of the step-up transformer 76, a high voltage pulse voltage is taken out from the output side of the step-up transformer 76, and the output high voltage pulse voltage is integrated to have a negative polarity. By generating the high voltage Vd, it is possible to efficiently form a continuous high voltage with substantially the same configuration regardless of whether the power source is the commercial AC voltage Va or the battery 136.

  Further, the discharge means 12 is provided with a switching means 15, and in conjunction with the switching operation of the switching means 15, the drive time of the discharge means 12 and the effective time of the auxiliary electrode 22 can be regulated, so that the amount of negative ions generated Can be manually changed to 3 levels. Further, by providing the air blowing means 30 at the same time so that the generated negative ions are forcibly discharged, the negative ions are accurately supplied to the human body and effectively used before disappearing.

  Hereinafter, the portable ion generator according to the present invention will be described in more detail based on an example in which the hair dryer 32 shown in FIGS. Here, as schematically shown in FIG. 2, the hair dryer 32 includes a horizontally long main body case 26 and a handle 28 that is swingably attached to the base end side of the main body case 26. .

  In the main body case 26, a motor that enables commercial air voltage Va supplied from the outside as a drive source, and a heat generating portion 38 including a coiled heater 36 to the front end side to blow air to the heat generating portion 38. A blower unit 44 including a fan 40 and a fan 42 is provided on the base end side, and a discharge unit 46 is provided in the heater 36 of the heat generating unit 38 to generate ions. Further, in conjunction with the switching operation of the changeover switch 48 and the electric circuit shown in FIG. 3 provided on the handle 28 side, the timing of blowing and ion generation is regulated and the amount of power supplied to the heat generating portion 38 is accommodated. The air temperature during blowing can be changed in multiple stages.

  Here, the air blower 44 full-wave rectifies the commercial AC voltage Va by the diode bridge 50 and rotates the fan 42 by the DC motor 40 driven by this voltage. In response to the operation, the first contact 52 is turned on, and air blowing at normal temperature without heating in the heat generating portion 38 is started.

  Next, the heat generating unit 38 turns on the second contact 54 in addition to the first contact 52 by the second-stage sliding operation of the changeover switch 48, and a half-wave rectified voltage is applied to the heater 36 via the diode 56. As a result, the heater 36 is driven by electric power that is half the rated value, and air is blown at an intermediate temperature. When the changeover switch 48 is further slid to the third stage, the third contact 58 connected in parallel with the diode 56 is also turned on, and the commercial AC voltage Va is directly applied to the heater via the first to third contacts 52, 54 and 58. As a result, the air is blown at a high temperature. In addition, since the structure of the above-mentioned ventilation part 44 and the heat_generation | fever part 38 is substantially the same as the past, the detailed description is abbreviate | omitted. Of course, it can be implemented by replacing with other known configurations.

  The present invention is characterized by the structure of the discharge portion 46 specifically exemplified in FIGS. 4 and 5, and is shown in FIG. 6A simultaneously with the turning on of the first contact 52 in the changeover switch 48. The commercial AC voltage Va is applied to the low voltage rectifier circuit 60 to start the operation.

  The low voltage rectifier circuit 60 performs half-wave rectification of the input commercial AC voltage Va with a diode 62 and then integrates it with a resistor 64 and a capacitor 66, whereby the peak value fluctuates around 100V as shown in FIG. Since the flow voltage Vb is formed, this pulsating voltage Vb is used as a drive voltage for the display circuit 70 and the pulse voltage generation circuit 72.

  The display circuit 70 includes a light emitting diode 74 on the main body case 26 or the handle 28, and lights the light emitting diode 74 with the voltage Vb output from the low voltage rectifier circuit 60, thereby displaying the operation of the discharge unit 46.

  The pulse voltage generation circuit 72 has a configuration in which a capacitor 80 is connected in series with the primary coil 78 of the step-up transformer 76 and a Sidac 82 is connected in parallel with the serial connection. The Sidac 82 is off while the applied voltage is low, but is of a standard that turns on when the value of the input pulsating voltage Vb exceeds 80 V, for example. Thus, the capacitor 80 is charged, and when the Sidac 82 is turned on, the capacitor 80 is suddenly discharged through the Sidac 82 and the primary coil 78 and the Sidac 82 is turned off. By repeating this operation periodically until the pulsating voltage Vb drops below 80V and the Sidac 82 is always turned off, the pulse voltage Vc generated intermittently as shown in FIG. It is generated in the primary coil 78 of the transformer 76.

  The pulse voltage Vc is boosted corresponding to the winding ratio between the primary coil 78 and the secondary coil 86 of the step-up transformer 76 and then is a high voltage composed of a diode 88 and a capacitor 90 connected in series with the secondary coil 86. Applied to the rectifier circuit 92. The high-voltage rectifier circuit 92 integrates the high-voltage pulse voltage intermittently output from the secondary coil 86, so that the negative-polarity high voltage Vd that fluctuates in the range of 2 to 4 kV as shown in FIG. And the voltage Vd is applied to the electrode portion 94. It should be noted that the specific circuit configuration for forming the high voltage Vd is not limited to the above, and it is needless to say that it can be implemented with appropriate modifications such as using a known booster circuit that has been used conventionally. .

  The electrode part 94 is unitized as shown in FIG. 5, and an example is shown in which the electrode part 94 is installed in a wind guide tube 98 disposed at the center of the hot air outlet 96 in the main body case 26 shown in FIG. If it is possible to discharge the main body case 26 to the outside, for example, an air passage dedicated to ion emission is provided on the peripheral surface of the main body case 26, and the electrode portion 94 is disposed therein. Alternatively, the arrangement position is not limited.

  In this embodiment, the electrode portion 94 is centered on the needle-like discharge electrode 16 having a sharp tip, the cylindrical counter electrode 20 is disposed around the electrode electrode 94, and the discharge electrode 16 and the counter electrode 20 are insulated from each other. It is isolated by the member 100. The insulating member 100 includes an insulating portion 102 that fills the inside of the counter electrode 20 while leaving the distal end portion of the discharge electrode 16, and a cylindrical isolation portion 104 that surrounds the distal end portion of the discharge electrode 16 facing forward. A sufficient distance is secured between the discharge electrode 16 and the counter electrode 20 to prevent corona discharge but other discharge such as spark discharge.

  Further, the negative electrode of the capacitor 90 of the high-voltage rectifier circuit 92 and the discharge electrode 16 are connected by a conductive wire 108 via a high resistance 106 of, for example, several MΩ, while the positive electrode of the capacitor 90 and the counter electrode 20 are connected by a conductive wire 110. Connecting. With this configuration, a negative high voltage Vd is applied to the discharge electrode 16 to generate a corona discharge limited to only the tip of the discharge electrode 16, and negative ions 112 can be generated inside the isolation portion 104. And

  The air guide tube 98 is located in front of the above-described isolation portion 104 and has a cylindrical first tube portion 114 having a diameter larger than that of the isolation portion 104, and the electrode portion 94 in a state of spreading from the proximal end side of the first tube portion 114. And a second cylindrical portion 116 having a truncated cone shape that surrounds and extends. A predetermined gap 122 is maintained between the air guide tube 98 and the electrode portion 94 by the support arm 118 so that the air flow 120 sent from the blower 44 through the air inlet 99 passes through the gap 122. When passing through and blown out from the ion emission port 24 at the tip of the first cylindrical portion 114, the negative ions 112 generated in the isolation portion 104 are attracted, and together with the air flow 120, the ion flow 124 forms the ion flow 124. It is released to the outside.

  Further, in the present invention, the potential of the counter electrode 20 is maintained at a substantially ground potential by connecting the counter electrode 20 and the earth line 18 on the electric circuit side via a high resistance 126 of about 1 to several MΩ, for example. To do.

  On the other hand, on the handle 28 or the main body case 26, the auxiliary electrode 22 made of a conductive member such as a metal plate or a conductive rubber is disposed at one or a plurality of positions so as to be exposed to a portion touched when grasped with a palm. At the same time, the auxiliary electrode 22 and the counter electrode 20 in the main body case 26 are connected to each other through a high resistance 128 of about several MΩ, for example, so as to have substantially the same potential.

  As the conductive member used as the auxiliary electrode 22 described above, for example, natural rubber or synthetic rubber, conductive material (conductive carbon such as furnace carbon or acetylene black, conductive titanium oxide, conductive zinc oxide, etc.) Conductive rubber formed by filling can be used.

  By using such a conductive rubber, a metal plate may feel cold and uncomfortable when gripped, but it can be prevented and it is convenient to prevent slipping. Specifically, conductive silicone rubber excellent in oil resistance, heat resistance, and ozone resistance is used without requiring various additives that contaminate and corrode electronic components such as softeners and anti-aging agents. The category of the conductive rubber includes a conductive elastomer in which an elastomer resin, which is a polymer material exhibiting rubber-like elasticity near normal temperature, is filled with a conductive substance. Further, although there is no anti-slip effect, various conductive resins can be used as the auxiliary electrode 22 if only the coldness when gripping is prevented. Note that if the filling amount of the conductive material is adjusted to be small, the resistance value can be increased, so that the high resistance 128 can be omitted.

  By providing the auxiliary electrode 22 as described above, the area of the counter electrode 20 is substantially increased, the area of replenishing electrons during discharge is increased, and negative ions can be generated efficiently. Further, when the auxiliary electrode 22 is brought into contact with the human body, the earth line 18 and the counter electrode 20 in the main body case 26 are connected to a part of the human body via the auxiliary electrode 22, and electrons charged in the human body are discharged to the earth line 18 side. Thus, while preventing the human body from being charged to a negative potential, the electric field strength in the vicinity of the discharge electrode 16 can be maintained sufficiently large, and the amount of negative ions 112 generated can be further increased.

  For example, as shown in FIG. 7, the amount of negative ions 112 generated during the period of 0 to 1 and a half minutes when the auxiliary electrode 22 is not in contact with the human body is about 250,000 per cc at the maximum. However, the amount of ions increased to about 500,000 ions, which is about twice that from the point a when the human body was brought into contact with the auxiliary electrode 22, and the amount was maintained substantially constant over time. It was confirmed that

  As described above, the auxiliary electrode 22 can be used by forming a part or the whole of the handle 28 and the main body case 26 with a conductive material such as a metal plate, in addition to being provided exclusively for the auxiliary electrode 22. By using a metal screw or metal fitting provided for assembling the case in a divided shape as it is or by transforming it into a size or shape that can be contacted from the outside, an increase in the number of parts can be prevented.

  In addition, during use, it is possible to set the shape and position of the auxiliary electrode 22 so that it always comes into contact with the human body. For example, it is possible to select whether the auxiliary electrode 22 is touched or not touched with a fingertip. The production amount of negative ions 112 may be manually changed.

  Further, a dedicated switch that restricts the operation of the discharge part 46 without restricting the discharge part 46 on / off at the same time by the changeover switch 48 provided for turning on / off the blower part 44 may be provided. In that case, while the human body can always contact the auxiliary electrode 22 during use, the generation of negative ions 112 that stop energizing the discharge portion 46 in conjunction with the switching operation of a switch dedicated to ion generation provided separately. From the off state, the discharge unit 46 is operating, but the auxiliary electrode 22 is not connected to the earth line 18, and the auxiliary electrode 22 is connected to the earth line 18 by connecting the auxiliary electrode 22 to the earth line 18. It is also possible to change the amount of ion generation in three stages in conjunction with the switching operation of the switch to strong ion generation using.

  Next, FIG. 8 shows an example in which the present invention is applied to the hair brush 130, and the handle 28 is linearly formed in the axial direction from the center of the base end side of the body case 26 having the brush surface 132 on the lower surface side. And the discharge part 46 a is housed in the main body case 26. In addition, about the member which performs the substantially same function as the structure in the above-mentioned hair dryer 32, the detailed description is abbreviate | omitted by attaching | subjecting the same number.

  The brush surface 132 is oval or rectangular long in the extending direction of the handle 28, and has one or a plurality of ion emission ports 24, and brush hairs 134 are planted over substantially the entire surface excluding the ion emission ports 24. It is installed.

  The structure of the discharge part 46a and the electrode part 94a accommodated in the main body case 26 adopts the same or similar structure as the structure excluding the heat generating part 38 from those illustrated in FIGS. 3 to 5 applied to the hair dryer 32 described above. It is also possible to do. That is, the air blower 44 is driven using the commercial AC voltage Va, and the negative ions 112 are forcibly blown out from the ion discharge port 24 by the air flow 120, and the auxiliary electrode 22 is provided in the handle 28 portion. .

  However, in this embodiment, for example, various batteries 136 such as a dry battery or a secondary battery having an output voltage of about 3 V are built in the main body case 26 and the handle 28, and the output voltage from the battery 136 is not shown in the inverter. A circuit is used to convert the voltage into an AC voltage of about 100 V, and this voltage is used as the input voltage of the pulse voltage generation circuit 72 and the drive voltage of the display circuit 70 shown in FIG. 4 without using the commercial AC voltage Va. It can be driven only by the battery 136. Further, the negative ions 112 are supplied to the hair by using the ionic wind generated at the time of discharge or the natural convection associated with styling without providing the blower 44 shown in FIG.

  Furthermore, the present embodiment is characterized in that the auxiliary electrode 22 is provided on the brush surface 132 in addition to or on the handle 28 and the main body case 26. Here, the two auxiliary electrodes 22a and 22b provided on the brush surface 132 are formed in two strips along both side edges of the brush surface 132 in the width direction. Further, the auxiliary electrode 22 can be disposed only on the brush surface 132. However, in the illustrated example, the auxiliary electrode 22 extends to both side surfaces 27 and 27 of the main body case 26 and has a substantially L-shaped cross section. is doing.

  With this configuration, when the changeover switch 48a provided on the handle 28 is turned on, the switch contact 52a is turned on to drive the discharge unit 46a, and at the same time, the light emitting diode 74 of the display circuit 70 is energized to drive the discharge unit 46a. Display inside.

  In the state where the discharge unit 46a is driven and negative ions are blown out from the ion emission port 24, the brush hair 134 is inserted into the hair 150 as shown in FIG. Then, first, the first auxiliary electrode 22a provided at the front edge discharges unnecessary electrons charged in the hair 150. In this state, after brushing with the bristle 134 while causing the ion flow 124 emitted from the center of the brush surface 132 to act on the hair 150, the excess electrons are discharged by the second auxiliary electrode 22b, Neutralize the charged state of the hair 150 and restore it. Here, by extending the auxiliary electrode 22 to the side surface 27 of the main body case 26, even when brushing while curling, the auxiliary electrodes 22a and 22b can be brought into contact with the hair 150 and the negatively charged state can be effectively neutralized. It is.

  The auxiliary electrode 22 can be provided over the entire circumference along the peripheral edge of the brush surface 132, or conversely, can be provided only on one side edge. However, in the case where a plurality of ion emission openings 24 are provided in a dispersed manner or the diameter of the ion emission openings 24 is large in the axial direction, the ion emission openings 24 are sandwiched in the width direction and the length of the ion emission openings 24 in the longitudinal direction. It is preferable that the length of the auxiliary electrode 22 is set to be substantially equal to or longer than that. With this configuration, the charging of the hair due to the negative ions blown from the ion discharge port 24 is reliably neutralized.

  Besides, the auxiliary electrode 22 is made of a metal material separate from the main body case 26, and the brush surface 132 for fixing the base end of the bristles 134 is made of a conductive member such as conductive rubber. Can also be used as the auxiliary electrode 22. In this case, the conductive member can be provided on the entire surface of the brush surface 132. However, in order to enhance the spraying effect of the negative ions 112, the conductive member is preferably provided only at the peripheral position as described above.

  Further, the bristle 134 can be made of a conductive resin or a conductive rubber to form the auxiliary electrode 22. In this case, since the bristle 134 reaches the deep part of the hair 150, the charged state of the hair 150 by negative ions can be effectively neutralized, and negative ions can be effectively supplied during the next brushing.

  9 to 11 further show an example in which the present invention is applied to a hair iron 138. In this embodiment, instead of the brush surface 132 of the hair brush 130 described above, the lower surface side of the body case 26 is shown. An iron part 140 is provided. In addition, about the member which performs the function substantially the same as the structure in the above-mentioned hair dryer 32 and the hairbrush 130, the detailed description is abbreviate | omitted by attaching | subjecting the same number.

  The iron part 140 is configured by a pair of a main body case lower surface 142 and an upper surface 146 of a holding arm 144 that is swingably attached to a rotary shaft 143 provided at a base end position of the handle 28. The holding arm 144 is normally urged to open by a spring body 145 such as a coil spring. As illustrated in FIG. 11, the hair is held against the spring body 145 between the lower surface 142 of the main body case and the upper surface 146 of the holding arm 144. By sandwiching 150, it is possible to heat and press the hair 150 with the rectangular heating surfaces 152 and 152 provided in the longitudinal direction of the central portion while combing the hair 150 with the hairstyling comb 148 provided on both sides in the width direction. To do.

  The heating surface 152 is formed of a hot plate such as a metal plate. In this embodiment, the heating plate 152 is heated by a heater 36a using a known heating element such as PTC, for example, of silicone rubber. This is done by being built in contact with the back surface side of the heating surface 152 in a state of being electrically insulated through such an insulating member, but the configuration is limited, for example, the heating plate itself is integrated with the heater. It is not something. Further, it is not necessary to provide the heater 36a on both the upper and lower heating surfaces 152 and 152, and the heater 36a is provided only on one heating surface to generate heat, and the hair is heated and pressed in a pair with the other heating surface. You can also Even in this case, the overall configuration of the iron part 140 is substantially the same as that of the prior art, and thus detailed description thereof is omitted.

  In the present invention, the discharge part 46 is further provided in the main body case 26 so that negative ions can be sprayed on the hair 150 being processed. The circuit configuration of the discharge unit 46 is the same as or similar to that shown in FIG.

  One set of electrode portions 94b provided in the discharge portion 46 is arranged in parallel to the outer side of the hairstyling comb 148 at the peripheral position of the lower surface 142 of the main body case. In the example, three discharge electrodes 16 are provided. On the other hand, by providing a ring-shaped counter electrode 20 spaced apart from each discharge electrode 16, corona discharge is caused in the vicinity of the tip of the needle-shaped discharge electrode 16. It is possible to generate negative ions in a substantially band shape.

  Of course, the configuration of the electrode portion 94b is not limited as long as it is a configuration capable of generating negative ions, such as that shown in FIG. Further, it is not necessary to provide a plurality of electrode portions 94b on the outside of the hairstyling comb 148, and it is possible to provide one on each side, and at least one electrode portion 94b is sufficient, for example.

  Here, the ion emission opening 24 has a narrow slit shape corresponding to the arrangement position of the electrode portion 94b described above, and further, the minus is generated in the vicinity of the discharge electrode 16 by inclining the opening direction obliquely outward. The ion flow 124 is blown out in a direction away from the main body case 26 by the air flow 120 generated by the fan 42.

  Further, at least one of the hot plates constituting the heating surfaces 152 and 152 facing each other is formed of a conductive member such as a metal plate, and the heating surface 152 formed of the conductive member is used as the auxiliary electrode 22. The auxiliary electrode 22 can be provided with a separate electrode on or near the heating surface 152 instead of or in addition to using the heating surface 152 as an electrode. The auxiliary electrode 22 may be provided on the handle 28 or the body case 26.

  When the upper and lower heating surfaces 152 and 152 are made of metal, the entire surface is further covered with conductive rubber or conductive resin, and this is used as the hot plate and auxiliary electrode 22. Can do. This can neutralize the charged state of the hair due to negative ions and reduce the feeling of being hot when touching the heating surface 152.

  With this configuration, when the switch 48 is turned on, the motor 40 of the blower unit 44 that rotationally drives the fan 42, the heater 36a that heats the heating surface 152, the discharge unit 46, and the light emitting diode that displays that the discharge unit 46 is being driven. At the same time, drive power is supplied to 74 and the operation is started. At this time, the power supplied to the heater 36a is automatically controlled so that the temperature of the heating surface 152 is maintained at around 140 ° C., for example.

  Then, the hair 150 is slid in the direction of the arrow in FIG. Then, as a result of the negative ions blown out from the ion release port 24a on the front edge side in the sliding direction adhering to the hair 150, the hair 150 is replenished with moisture and moisturized and softened.

  The portion of the hair 150 that has been replenished with moisture passes through the space between the upper and lower heating surfaces 152 and 152 as the hair iron 138 slides, and is compressed simultaneously with the heating. Whether the heating surface 152 is flat or corrugated. The predetermined brazing corresponding to the difference in shape is performed, and at the same time, the charged state is neutralized by the action as the auxiliary electrode 22. Further, the neutralized hair 150 passes under the ion release port 24b on the trailing edge side, and thus negative ions 112 are sprayed again. As a result, the hair is compressed and dried between the upper and lower heating surfaces 152 and 152. It is possible to replenish the water to 150 and restore the moist state.

  At that time, as shown in FIG. 10, the pair of ion emission ports 24a and 24b and the heating surfaces 152 and 152 have substantially the same length in the axial direction. ) Can be reliably pressed after the hair 150 is replenished, and negative ions that have been replenished and charged can be uniformly removed and neutralized. Even after the pressing, some moisture remains but is insufficient, so that after the removal, negative ions are fed by the ion discharge port 24b at the rear in the sliding direction so that moisture can be regained.

  Further, since the ion emission port 24 is formed to be inclined outward, a sufficient isolation state is provided between the auxiliary electrode 22 at the center of the iron part 140 and the ion flow 124 blown from the ion emission port 24. Thus, before the negative ions reach the hair 150, they are captured by the auxiliary electrode 22 and prevented from disappearing. A similar effect can be achieved by providing a rib 154 between the auxiliary electrode 22 and the ion emission port 24 as shown in FIG.

  In addition, the portable ion generator 14 to which the present invention is applied is not limited to a product for the purpose of hair care as described above, and is used by spraying negative ions 112 directly or indirectly on the human body. If it is, it can implement substantially similarly and is not limited. For example, as shown in FIG. 12, the electrode part 94 is limited to one set, and negative ions generated therefrom can be divided into a plurality of ion flows 124 and 124 by the air flow 120 and the ventilation path 156.
