従来、この種の加湿装置の一例として静電霧化装置が知られている（例えば、特許文献１参照）。
以下、その静電霧化装置について図１２および図１３を参照しながら説明する。

特開２００５−２９６７５３号公報（［００１６］［００１７］図１、図２） Conventionally, an electrostatic atomizer is known as an example of this type of humidifier (see, for example, Patent Document 1).

Cooling the discharge electrode in the cooling unit makes it easy for moisture to condense and adhere to the discharge electrode from the humidified high-humidity air. Discharge occurs stably from the electrode to the counter electrode and is negative even in the dry state in winter. The on reduction by fine water droplets can be stably supplied. Also, since the cooling capacity of the cooling section is not particularly increased, the heat dissipation capacity of the heat dissipation section is insufficient (the heat dissipation area of the heat dissipation section is small, the amount of air passing through the heat dissipation section and the passing air speed are small, and the ventilation temperature is Even under high conditions, the electrostatic atomization function can be sufficiently exhibited.
In addition, a heat exchanging part having a cooling part and a heat radiating part is provided on the partition wall separating the air inlet side and the air outlet side, and the cooling part and the heat radiating part are provided on the air inlet side and the air outlet side.

The heat radiation part is connected to the heat radiation fin, and by mounting a small and light Peltier element, it is possible to cool and discharge the discharge electrode in a space-saving manner without requiring large equipment. Since the electrode is in a high-humidity airflow, the cooling capacity can be reduced, and the shape of the radiating fin of the heat generating part can also be reduced.
According to a third aspect of the present invention, the electrostatic atomizer includes an insulating holding frame that is fitted into an opening provided in the partition wall, and the discharge electrode, the counter electrode, and the heat exchange unit are integrated with the holding frame. It can be easily attached to and detached from the opening of the partition wall to improve workability, and the insulating holding frame ensures safety on the high voltage side, and the air flow path The air outlet side and the air inlet side can be reliably separated from each other, and the radiating fin can be reduced in size, so that the radiating fin can be mounted on the holding frame integrally with the heat generating portion.
According to a fourth aspect of the present invention, the surrounding wall portion surrounding the discharge electrode is formed in the holding frame, and the front shape of the surrounding wall portion is formed in a substantially U-shape facing downward with the lower part open.

The invention according to claim 8 is provided with a wind speed adjusting means for covering the discharge electrode and the counter electrode of the electrostatic atomizer in the air flow path, and the wind speed adjustment means supplies a small amount of air to the discharge electrode. Since the wind speed is high in the air flow path where the electrostatic atomizer is located, it is not possible to stably condense condensed water on the discharge electrode as it is, but the wind speed adjusting means forms a bypass air path with a low wind speed. In addition, a minute air volume can be supplied to the discharge electrode without blowing off the condensed water adhering to the discharge electrode with wind force, and a stable electrostatic atomization function can be exhibited.
According to the ninth aspect of the present invention, an intake opening having a small opening area is provided at a lower portion of a frame constituting the wind speed adjusting means, and a discharge opening having a large opening area is provided at an upper front surface of the frame.

By rectifying with a simple lattice, it is possible to increase the attractive force near the discharge opening by aligning the ventilation direction, and reliably attract the negative ionized fine water droplets to the air flow path side.

また、静電霧化装置８は、冷却部１１と放熱部１２を設けた熱交換部１３としてのペルチェ素子１４を備え、ペルチェ素子１４の冷却部１１に放電極９を接続するとともに、放熱部１２に放熱フィン１５を接続している。静電霧化装置８は絶縁性の保持枠１７を備え、保持枠１７には放電極９と対向電極１０および熱交換部１３が一体に搭載されている。保持枠１７を隔壁７に設けた開口部１６に嵌着可能に設け、静電霧化装置８は保持枠１７を介して隔壁７に固定されている。
また、放電極９を囲む包囲壁部１８を保持枠１７に形成し、包囲壁部１８の正面形状を下部が開放した下向きの略コ字形状に形成し、空気流路３の吹出口側２ａに放電極９と対向電極１０を配置し、空気流路３の吸込口側１ａに設けた迂回回路１９に熱交換部１３の放熱部１２を配置している。 As shown in FIGS. 1 to 7, in the humidifying device of the present embodiment, the main body 6 is provided with a blower 4 and a humidifying means 5 in an air flow path 3 formed by communicating the inlet 1 and the outlet 2. A partition wall 7 is provided to separate the suction port side 1a and the outlet side 2a while securing the flow path of the air flow path 3, and an electrostatic atomizer 8 is attached to the partition wall 7. The electrostatic atomizer 8 includes a discharge electrode 9 to which a high voltage is applied, a counter electrode 10 provided to face the discharge electrode 9, and a heat exchange unit 13 provided with a cooling unit 11 and a heat dissipation unit 12. The discharge electrode 9 is cooled by the part 11 to attach moisture in the air. The discharge electrode 9 of the electrostatic atomizer 8, the counter electrode 10, and the cooling unit 11 of the heat exchange unit 13 are arranged on the outlet side 2 a that is downstream of the humidifying means 5, and the heat dissipation unit 12 of the heat exchange unit 13 is It arrange | positions at the suction inlet side 1a used as the upstream of the air blower 4. FIG.
The electrostatic atomizer 8 includes a Peltier element 14 as a heat exchanging unit 13 provided with a cooling unit 11 and a heat dissipation unit 12, and connects the discharge electrode 9 to the cooling unit 11 of the Peltier element 14, and 12 is connected to the radiation fin 15. The electrostatic atomizer 8 includes an insulating holding frame 17, and the discharge electrode 9, the counter electrode 10, and the heat exchange unit 13 are integrally mounted on the holding frame 17. A holding frame 17 is provided so as to be fitted in an opening 16 provided in the partition wall 7, and the electrostatic atomizer 8 is fixed to the partition wall 7 through the holding frame 17.
Further, the surrounding wall portion 18 surrounding the discharge electrode 9 is formed in the holding frame 17, the front shape of the surrounding wall portion 18 is formed in a substantially downward U shape with the lower part open, and the air outlet side 2 a of the air flow path 3. The discharge electrode 9 and the counter electrode 10 are arranged on the side, and the heat radiating part 12 of the heat exchanging part 13 is arranged in the bypass circuit 19 provided on the suction port side 1a of the air flow path 3.

上記構成において、空気流路３内に送風機４と加湿手段５を設け、冷却部１１で放電極９を冷却して空気中の水分を付着させるようにしているので、加湿装置の本体６が室内の乾燥した使用環境に置かれていても、冷却部１１に接続する放電極９を冷却することにより、吹出口側２ａでは加湿手段５により加湿された高湿度の空気中から水分が放電極９に結露し付着しやすくなる。すなわち結露しやすい放電極９から対向電極１０に安定した状態で放電がなされ、負イオン化された微細水滴を不足なく生成することができ、室内が冬場の乾燥状態であっても、吹出口２より負イオン化された微細水滴を安定して供給することができる。
また、吹出口側２ａでは高湿度の空気中から水分が放電極９に結露し付着しやすくなるので、吸込口側１ａに設けた冷却部１１の冷却能力を特別大きくする必要もなく、放熱部１２の放熱能力が不充分な条件（放熱部の放熱面積が小さく、また放熱部への通過風量や通過風速が少なく、あるいは通風温度が高いような条件）であっても、静電霧化機能を充分に発揮させることができる。 In the above configuration, the air blower 4 and the humidifying means 5 are provided in the air flow path 3, and the discharge electrode 9 is cooled by the cooling unit 11 so that moisture in the air adheres thereto. Even when placed in a dry use environment, the discharge electrode 9 connected to the cooling unit 11 is cooled, so that moisture is discharged from the high-humidity air humidified by the humidifying means 5 on the outlet side 2a. Condensation tends to occur on the surface. That is, discharge is performed in a stable state from the discharge electrode 9 which is likely to condense to the counter electrode 10, and negative ionized fine water droplets can be generated without a shortage. Negative ionized fine water droplets can be stably supplied.
Further, since moisture is easily condensed and attached to the discharge electrode 9 from the air in the high humidity at the air outlet side 2a, it is not necessary to specially increase the cooling capacity of the cooling part 11 provided on the air inlet side 1a. Electrostatic atomization function even under conditions where heat dissipation capacity of 12 is insufficient (conditions where the heat dissipation area of the heat dissipating part is small, the amount of air passing through the heat dissipating part, the passing air speed is low, or the air passing temperature is high) Can be fully exhibited.

また、冷却部１１と放熱部１２を有する熱交換部１３を空気流路３の吸込口側１ａと吹出口側２ａとを隔てる隔壁７に設けて、冷却部１１と放熱部１２を空気流路３の吸込口側１ａと吹出口側２ａに配することで、熱交換部１３の熱交換が効率良く行える。
また、静電霧化装置８を、冷却部１１と放熱部１２を設けた熱交換部１３としてのペルチェ素子１４を備え、ペルチェ素子１４の冷却部１１に放電極９を接続するとともに、放熱部１２に放熱フィン１５を接続しているので、小型軽量のペルチェ素子１４の搭載により、大掛りな設備を必要とせず、省スペースで放電極９を冷却して結露させることができる。さらに放電極９は高湿度の気流内にあるので結露しやすく、冷却能力を少なく抑えることができ、放熱部１２の放熱フィン１５の形状も小型化することができる。
また、静電霧化装置８に、隔壁７に設けた開口部１６に嵌着される絶縁性の保持枠１７を備え、保持枠１７に放電極９と対向電極１０と熱交換部１３とを一体に搭載しているので、隔壁７の開口部１６への着脱が容易に行えて作業性を向上することができるとともに、放熱フィン１５を小型化できるので、放熱フィン１５を放熱部１２と密接状態で、保持枠１７に一体に搭載することができる。
また絶縁性の保持枠１７が高電圧側の安全を確保するとともに、空気流路３の吹出口側２ａと吸込口側１ａとを確実に隔てることができる。
また、放電極９を囲む包囲壁部１８を保持枠１７に形成し、包囲壁部１８の正面形状を下部が開放した下向きの略コ字形状に形成しているので、保持枠１７の包囲壁部１８の下部から風を導入しやすくするとともに、上部で風向変更して負イオン化された微細水滴を前方へ案内することができ、さらに包囲壁部１８内で生成された余分な結露水を開放する下方に流下させることにより、放電極９からの異常な放電を未然に防ぐことができる。
また、空気流路３の吹出口側２ａに放電極９と対向電極１０を配置し、空気流路３の吸込口側１ａに設けた迂回回路１９に熱交換部１３の放熱部１２を配置したので、１つの送風機の吹出口側と吸込口側の風速差を利用して、負イオン化された微細水滴の生成を効率よく行うことができ、吸込口側では迂回風路により放熱部の放熱能力をさらに少なくして、放電極やその周囲に余分な結露水が生成されるのを防ぐことができる。
（実施の形態２） Further, a heat exchanging part 13 having a cooling part 11 and a heat radiating part 12 is provided on the partition wall 7 separating the air inlet side 1a and the air outlet side 2a of the air flow path 3, and the cooling part 11 and the heat radiating part 12 are connected to the air flow path. 3, the heat exchange of the heat exchange part 13 can be performed efficiently.
In addition, the electrostatic atomizer 8 includes a Peltier element 14 as a heat exchanging unit 13 provided with a cooling unit 11 and a heat dissipation unit 12, and the discharge electrode 9 is connected to the cooling unit 11 of the Peltier element 14, and the heat dissipation unit Since the radiating fins 15 are connected to 12, by mounting the small and light Peltier element 14, it is possible to cool and discharge the discharge electrode 9 in a small space without requiring a large facility. Further, since the discharge electrode 9 is in a high-humidity air stream, it is easy to condense, the cooling capacity can be reduced, and the shape of the heat radiation fin 15 of the heat radiation portion 12 can be reduced.
Further, the electrostatic atomizer 8 is provided with an insulating holding frame 17 fitted into the opening 16 provided in the partition wall 7, and the discharge electrode 9, the counter electrode 10, and the heat exchange unit 13 are provided on the holding frame 17. Since they are integrally mounted, the partition 7 can be easily attached to and detached from the opening 16 to improve workability, and the radiating fins 15 can be miniaturized. In this state, it can be integrally mounted on the holding frame 17.
Further, the insulating holding frame 17 can ensure safety on the high voltage side and can reliably separate the air outlet side 2a and the air inlet side 1a of the air flow path 3.
Further, since the surrounding wall portion 18 surrounding the discharge electrode 9 is formed in the holding frame 17 and the front shape of the surrounding wall portion 18 is formed in a substantially downward U shape with the lower part open, the surrounding wall of the holding frame 17 It is possible to easily introduce wind from the lower part of the part 18, change the wind direction at the upper part and guide forward the negative ionized fine water droplets, and release the extra condensed water generated in the surrounding wall part 18. By making it flow downward, abnormal discharge from the discharge electrode 9 can be prevented in advance.
Further, the discharge electrode 9 and the counter electrode 10 are arranged on the air outlet side 2 a of the air flow path 3, and the heat radiation part 12 of the heat exchanging part 13 is arranged in the bypass circuit 19 provided on the suction port side 1 a of the air flow path 3. Therefore, it is possible to efficiently generate negative ionized fine water droplets by utilizing the difference in wind speed between the blower outlet side and the suction port side of one blower. Can be further reduced to prevent generation of excessive dew condensation water around the discharge electrode and its surroundings.

上記構成において、空気流路３Ａの吹出口側２ａに縮小部２０を設け、縮小部２０の近傍に静電霧化装置８Ａを配しているので、吹出口側２ａの縮小部２０では狭い領域を加湿空気が通過するため、静電霧化装置８Ａで負イオン化された微細水滴を加湿気流に乗せやすくすることができる。
また、空気流路３Ａの縮小部２０から吹出口２Ａに至る流路を拡大するとともに、吹出口２Ａに風向分散板２１を設けたので、負イオン化された微細水滴を含む加湿空気は、吹出口２Ａ方向に拡大しながら流れ、吹出口２Ａに設けた風向分散板２１によりさらに拡大し、室内に広範囲に拡散することができる。
（実施の形態３） As shown in FIGS. 8 and 9, the humidifying device of the present embodiment is provided with a reducing portion 20 on the air outlet side 2 a of the air flow path 3 A, and an electrostatic atomizing device 8 A is disposed near the reducing portion 20. The flow path extending from the reduced portion 20 of the air flow path 3A to the air outlet 2A is enlarged, and a wind direction dispersion plate 21 is provided at the air outlet 2A.
In the above configuration, since the reducing portion 20 is provided on the air outlet side 2a of the air flow path 3A, and the electrostatic atomizer 8A is disposed in the vicinity of the reducing portion 20, the narrow portion of the reducing portion 20 on the air outlet side 2a.

本実施の形態の加湿装置は、図１０および図１１に示すように、空気流路３Ｂ内の静電霧化装置８Ｂの放電極９Ａと対向電極１０Ａを覆う風速調整手段２２を設け、風速調整手段２２を放電極９Ａに微小風量を供給するように設け、風速調整手段２２を構成する枠体２３の下部に開口面積の小さい吸気開口部２４を設け、枠体２３の上部前面に開口面積の大きい放出開口部２５を設け、放出開口部２５より下部の枠体２３の表面に空気流路３Ｂの風向に直交する誘引促進板２６を突設している。
また、風速調整手段２２の放出開口部２５を空気流路３Ｂに対して略平行に設け、放出開口部２５に空気流路３Ｂの通風方向に平行な格子２７を設けている。 As shown in FIGS. 10 and 11, the humidifier of the present embodiment is provided with wind speed adjusting means 22 that covers the discharge electrode 9 A and the counter electrode 10 A of the electrostatic atomizer 8 B in the air flow path 3 B. The means 22 is provided so as to supply a small amount of air to the discharge electrode 9A, the intake opening 24 having a small opening area is provided at the lower part of the frame 23 constituting the wind speed adjusting means 22, and the opening area of the upper part of the frame 23 is adjusted to the opening area. A large discharge opening 25 is provided, and an attraction promoting plate 26 is provided on the surface of the frame 23 below the discharge opening 25 so as to be orthogonal to the air flow direction of the air flow path 3B.
Further, the discharge opening 25 of the wind speed adjusting means 22 is provided substantially parallel to the air flow path 3B, and the discharge opening 25 is provided with a lattice 27 parallel to the air flow direction of the air flow path 3B.

上記構成において、空気流路３Ｂ内の静電霧化装置８Ｂの放電極９Ａと対向電極１０Ａを覆う風速調整手段２２を設け、風速調整手段２２を放電極９Ａに微小風量を供給するように設けたので、静電霧化装置８Ｂの位置する空気流路３Ｂでは風速が大きいため、このままでは放電極９Ａに結露水を安定して結露させることができないが、風速調整手段２２が風速の小さいバイパス風路を形成し、放電極９Ａに付着した結露水を風力で吹き飛ばすことなく放電極９Ａに微小風量を供給することができ、安定した静電霧化機能を発揮することができる。
また、風速調整手段２２を構成する枠体２３の下部に開口面積の小さい吸気開口部２４を設け、枠体２３の上部前面に開口面積の大きい放出開口部２５を設けているので、枠体２３の下部に設けた開口面積の小さい吸気開口部２４は、枠体２３内への浸入風量を少なく制限するとともに、枠体２３の上部前面に設けた開口面積の大きい放出開口部２５は、枠体２３内で生成された負イオン化された微細水滴を、枠体２３外の空気流路３Ｂに乗せやすくすることができる。
また、放出開口部２５より枠体２３の表面に空気流路３Ｂの風向に直交する誘引促進板２６を突設して設けたので、誘引促進板２６で枠体２３外の加湿気流に乱流を発生させ、一部の気流を高速化して誘引効果を高めることにより、負イオン化された微細水滴は枠体２３外の空気流路３Ｂ側に誘引されて搬送することができる。
また、風速調整手段２２の放出開口部２５を空気流路３Ｂに対して略平行に設け、放出開口部２５に面して放電極９Ａを設けたので、空気流路３Ｂ側へ負イオン化された微細水滴が誘引されやすくなり、さらに放電極９Ａからのイオン風による押し出し力が働き、負イオン化された微細水滴は放出開口部２５を通過して空気流路側へと放出される。
また、放出開口部２５に空気流路３Ｂの通風方向に平行な格子２７を設けたので、放出開口部２５付近に発生する乱流を、空気流路３Ｂの通風方向に平行な格子２７で整流化することにより、通風方向を整えて放出開口部２５付近の誘引力を高め、負イオン化された微細水滴を空気流路３Ｂ側へ確実に誘引することができる。 In the above configuration, the wind speed adjusting means 22 that covers the discharge electrode 9A and the counter electrode 10A of the electrostatic atomizer 8B in the air flow path 3B is provided, and the wind speed adjustment means 22 is provided so as to supply a small amount of air to the discharge electrode 9A. Therefore, since the wind speed is high in the air flow path 3B where the electrostatic atomizer 8B is located, the dew condensation water cannot be stably condensed on the discharge electrode 9A as it is, but the wind speed adjusting means 22 is a bypass with a low wind speed. A fine air volume can be supplied to the discharge electrode 9A without forming the air path and blowing the condensed water adhering to the discharge electrode 9A with wind force, and a stable electrostatic atomization function can be exhibited.
Further, since the intake opening 24 having a small opening area is provided at the lower part of the frame 23 constituting the wind speed adjusting means 22 and the discharge opening 25 having a large opening area is provided at the upper front surface of the frame 23, the frame 23 The intake opening 24 with a small opening area provided in the lower part of the frame restricts the amount of inflow air into the frame body 23 and the discharge opening part 25 with a large opening area provided in the upper front surface of the frame body 23 has a frame body. It is possible to easily place the negative ionized fine water droplets generated in the air flow path 3 B outside the frame body 23.
In addition, since the attracting promotion plate 26 is provided on the surface of the frame body 23 from the discharge opening 25 so as to protrude perpendicular to the air flow direction of the air flow path 3B, the attraction promoting plate 26 turbulently flows into the humid airflow outside the frame body 23. By increasing the speed of a part of the airflow and enhancing the attraction effect, the negative ionized fine water droplets can be attracted to the air flow path 3B side outside the frame body 23 and conveyed.
Further, since the discharge opening 25 of the wind speed adjusting means 22 is provided substantially parallel to the air flow path 3B, and the discharge electrode 9A is provided so as to face the discharge flow path 25, it is negatively ionized toward the air flow path 3B. The fine water droplets are easily attracted, and the pushing force by the ion wind from the discharge electrode 9A works, so that the negative ionized fine water droplets are discharged to the air flow path side through the discharge opening 25.
Further, since the lattice 27 parallel to the ventilation direction of the air flow path 3B is provided in the discharge opening 25, the turbulent flow generated near the discharge opening 25 is rectified by the lattice 27 parallel to the ventilation direction of the air flow path 3B. As a result, the direction of ventilation can be adjusted to increase the attractive force in the vicinity of the discharge opening 25, and negative ionized fine water droplets can be reliably attracted to the air flow path 3B side.

It is effective for an air conditioner with a humidifying function equipped with an electrostatic atomizer.
