　また本発明は、モータと、前記モータの出力軸に連結して前記モータにより回転駆動されるファンと、空気中で放電してイオンを発生させるイオン発生器とを備えるイオン発生機能付き送風機において、前記イオン発生器は、前記モータを収納する部材と一体に形成した収納部に収納してあることを特徴とする。 Further, the present invention is a blower with an ion generation function comprising a motor, a fan connected to an output shaft of the motor and driven to rotate by the motor, and an ion generator that generates ions by discharging in the air. The ion generator is housed in a housing formed integrally with a member that houses the motor.
　この構成によると、モータを包囲して保護する樹脂等のキャビネット内部に上記イオン発生器を収納する。これにより、高電圧が印加されるイオン発生器をモータを収納するキャビネットの内側に設けてあるから、使用者等が触れることを防止することができ、安全性を確保することができる。 ¡According to this configuration, the ion generator is housed inside a resin cabinet that surrounds and protects the motor. Thereby, since the ion generator to which a high voltage is applied is provided inside the cabinet that houses the motor, it is possible to prevent a user or the like from touching and to ensure safety.
　また本発明は、イオン発生器を収納するキャビネットには空気を流通するための開口を設けるとともに、安全距離を確保してイオン発生器を設ける。これにより、送風機能に悪影響をほとんど与えず、同時に高電圧部分に使用者等が触れることを防止することができ、安全性を確保することができる。 Further, according to the present invention, the ion generator is provided with an opening for circulating air in the cabinet for storing the ion generator and securing a safe distance. As a result, the air blowing function is hardly adversely affected, and at the same time, the user or the like can be prevented from touching the high voltage portion, and safety can be secured.
　また本発明は、イオン発生器の放電電極の位置をファンの半径方向の距離の半分（略中間部）としている。この構成により、らせん気流を送出するプロペラファンを使用していても送風機前方と送風機周囲方向にイオンがバランスよく送出される。 Also, in the present invention, the position of the discharge electrode of the ion generator is set to half the distance in the radial direction of the fan (substantially intermediate portion).

　基台１には支柱２が立設してある。支柱２の上端部にはモータ３１等を備える駆動部３が取付けてある。駆動部３は概観が略円柱形をなすモータ３１の本体と、該モータ３１の本体の一側から突出する出力軸３２とを備えている。出力軸３２の先端部には、図２に示すように雄螺子部３３が設けてある。さらに、出力軸３２には、先端部から適長離隔した位置に、軸長方向に直交するように後述するファン４を係止するためのファンボス止ピン３４が取り付けられている。 The base 1 has a column 2 upright. A driving unit 3 including a motor 31 and the like is attached to the upper end portion of the column 2. The drive unit 3 includes a main body of a motor 31 whose appearance is substantially cylindrical, and an output shaft 32 protruding from one side of the main body of the motor 31. As shown in FIG. 2, a male screw portion 33 is provided at the distal end portion of the output shaft 32. Furthermore, a fan boss stop pin 34 for locking the fan 4 described later is attached to the output shaft 32 at a position separated from the tip by an appropriate length so as to be orthogonal to the axial length direction.
　またモータ３１の出力軸３２には、該出力軸３２の回転に伴って一体的に回転するファン４がファンボス止ピン３２により係止して取付けられる。出力軸３２に取付けられるファン４はプロペラファンであり、ボス部４２と羽根４１とを備える。ボス部４２は円筒状に形成され、モータ３１の出力軸３２に外嵌される。羽根４１はボス部４２に周方向に等配をなして複数設けられる。 Further, the fan 4 that rotates integrally with the rotation of the output shaft 32 is fixedly attached to the output shaft 32 of the motor 31 by the fan boss stop pin 32. The fan 4 attached to the output shaft 32 is a propeller fan and includes a boss portion 42 and blades 41. The boss portion 42 is formed in a cylindrical shape and is fitted on the output shaft 32 of the motor 31. A plurality of blades 41 are provided on the boss portion 42 at equal intervals in the circumferential direction.
　ファン４はモータ３１の出力軸３２にボス部４２を外嵌した状態にて、円筒状をなす固定部材としてのファンナット５が雄螺子部３３に螺合する。これにより、ファン４が出力軸３２に固定される。なお、ボス部４２は、ファンボス止ピン３４により、出力軸３２に対して相対回転しないように回り止めがなされる。つまり、ファンボス止ピン３４が嵌り込む凹部が、ボス部４２に形成されている。また、ファンボス止ピン３４にて、ファン４自体が出力軸３２の軸長方向にモータ３１側に移動しないようにしてある。 In the fan 4, the fan nut 5 as a cylindrical fixing member is screwed into the male screw portion 33 in a state where the boss portion 42 is externally fitted to the output shaft 32 of the motor 31. Thereby, the fan 4 is fixed to the output shaft 32. The boss portion 42 is prevented from rotating by the fan boss stop pin 34 so as not to rotate relative to the output shaft 32. That is, the boss portion 42 is formed with a recess into which the fan boss stop pin 34 is fitted. The fan boss stop pin 34 prevents the fan 4 itself from moving toward the motor 31 in the axial direction of the output shaft 32.
　このように取付けられたファン４には、該ファン４を包囲して保護するファンガード７が設けてある。ファンガード７はファンガード前部体７１とファンガード後部体７２とを備える。ファンガード前部体７１はファン４を前側から覆う。ファンガード後部体７２はファン４を後側から覆い、ファンガード前部体７１に係合する。 The fan 4 attached in this way is provided with a fan guard 7 that surrounds and protects the fan 4. The fan guard 7 includes a fan guard front body 71 and a fan guard rear body 72. The fan guard front body 71 covers the fan 4 from the front side. The fan guard rear body 72 covers the fan 4 from the rear side and engages with the fan guard front body 71.
　駆動部３は樹脂製の後キャビネット３０と後キャビネット３０に嵌合する樹脂製の前キャビネット６により覆われ、モータ３１の本体を収納する。ファンガード後部体７２は前キャビネット６に形成された雄螺子部６６と螺合する固定リング８と前キャビネット６とで挟持される。これにより、ファンガード７が固定される。 The drive unit 3 is covered with a resin rear cabinet 30 and a resin front cabinet 6 fitted into the rear cabinet 30 to house the main body of the motor 31. The fan guard rear body 72 is sandwiched between the front cabinet 6 and the fixing ring 8 screwed with the male screw portion 66 formed in the front cabinet 6. Thereby, the fan guard 7 is fixed.
　前キャビネット６は後キャビネット３０と嵌合してモータ本体３１を収納するだけでなく、上方に延伸されて後で説明する取っ手６０を構成する。前キャビネット６には例えばモータ３１の本体がネジ止めされ、さらにモータ３１の後部を覆う後キャビネット３０が取り外し可能に嵌合される。嵌合された後キャビネット３０は、前キャビネット６にネジ止めされている。したがって、ネジを外すことで前キャビに嵌合される後キャビネット３０が外され、モータ３１の本体部分が露出する。 The front cabinet 6 not only fits with the rear cabinet 30 to house the motor main body 31 but also extends upward to form a handle 60 described later. For example, the main body of the motor 31 is screwed to the front cabinet 6, and a rear cabinet 30 covering the rear portion of the motor 31 is detachably fitted. After being fitted, the cabinet 30 is screwed to the front cabinet 6. Therefore, the rear cabinet 30 fitted to the front cabinet is removed by removing the screw, and the main body portion of the motor 31 is exposed.
　樹脂製の後キャビネット３０は上方に伸びる隆起した壁体３０ａによって後述するイオン発生室３９を形成している。後キャビネット３０はイオン発生室３９を構成する壁体３０ａの上部をさらに上方へ延伸している。また、前キャビネット６は後キャビネット３０と同様に上部をイオン発生室３９よりも上方に延伸している。　 The resin rear cabinet 30 forms an ion generation chamber 39 to be described later by a raised wall body 30a extending upward. The rear cabinet 30 extends further upward from the upper portion of the wall body 30 a constituting the ion generation chamber 39. The front cabinet 6 extends upward from the ion generation chamber 39 in the same manner as the rear cabinet 30. *
　前キャビネット６及び後キャビネット３０は例えばイオン発生室３９の上面（頂部）と延伸させた部位との間に空間を形成して取っ手６０を形成する。この取っ手６０は前キャビネット６を上面として、下面に後キャビネット３０が嵌合される状態で形成された２層構成となっている。 For example, the front cabinet 6 and the rear cabinet 30 form a handle 60 by forming a space between the upper surface (top) of the ion generation chamber 39 and the stretched portion. The handle 60 has a two-layer structure formed with the front cabinet 6 as an upper surface and the rear cabinet 30 fitted into the lower surface.
　図３は扇風機１０の上部の模式的部分断面図を示している。イオン発生室３９にはファン４によって空気をイオン発生室３９内に流通させるために、吸込口３９ａと吹出口３９ｂが設けられている。吸込口３９ａは横長の複数の開口を有する格子状の開口部であって、吹出口３９ｂはハニカム状の開口を有する開口部である。なお、吸込口３９ａまた吹出口３９ｂの開口部は説明したものに限らず、周知の構造のものを適用できる。 FIG. 3 is a schematic partial cross-sectional view of the upper portion of the electric fan 10. The ion generation chamber 39 is provided with a suction port 39 a and a blowout port 39 b for allowing the air to flow through the ion generation chamber 39 by the fan 4. The suction port 39a is a lattice-shaped opening having a plurality of horizontally long openings, and the air outlet 39b is an opening having a honeycomb-shaped opening. In addition, the opening part of the suction inlet 39a or the blower outlet 39b is not restricted to what was demonstrated, The thing of a known structure is applicable.
　さらに、後キャビネット３０にはイオン発生室３９とモータ３１を仕切る（区画する）ように仕切り部３０ｂが例えば一体的に形成されている。仕切り部３０ｂによって吸込口３９ａ、吹出口３９ｂから異物が入り込んでも、モータ３１に異物が直接達することを防止する。 Furthermore, a partition 30b is integrally formed in the rear cabinet 30 so as to partition (partition) the ion generation chamber 39 and the motor 31, for example. Even if foreign matter enters from the suction port 39a and the air outlet 39b by the partition portion 30b, the foreign matter is prevented from reaching the motor 31 directly.
　取っ手６０を構成する後キャビネット３０の延伸部分はイオン発生室３９を形成し、イオン発生器９を収容する。イオン発生器９はイオンを発生する面をモータ３１側に向くように、イオンの発生面の反対面がイオン発生室３９を形成する壁体３０ａの頂部の内面（下面）に固定されている。 The extended portion of the rear cabinet 30 constituting the handle 60 forms an ion generation chamber 39 and accommodates the ion generator 9. In the ion generator 9, the opposite surface of the ion generation surface is fixed to the inner surface (lower surface) of the top of the wall body 30 a forming the ion generation chamber 39 so that the ion generation surface faces the motor 31 side.
　図４はイオン発生器９の模式的外観斜視図である。イオン発生器９は発生したイオンを放出する複数の放出孔が一面に設けられる。図４に示すイオン発生器９は、所謂針電極型の電極構造を有するイオン発生器９の例を示している。 FIG. 4 is a schematic external perspective view of the ion generator 9. The ion generator 9 is provided with a plurality of discharge holes for discharging the generated ions. The ion generator 9 shown in FIG. 4 shows an example of the ion generator 9 having a so-called needle electrode type electrode structure.
　このイオン発生器９は図５の回路図に示すように、昇圧回路９０ａとイオン発生素子９０ｂとを備えている。昇圧回路９０ａは１００Ｖの商用交流電圧が供給される端子Ｔ１及び端子Ｔ２間の印加電圧を昇圧する。イオン発生素子９０ｂは昇圧回路９０ａが昇圧した電圧を印加されてイオンを発生させる。 As shown in the circuit diagram of FIG. 5, the ion generator 9 includes a booster circuit 90a and an ion generating element 90b. The booster circuit 90a boosts the applied voltage between the terminal T1 and the terminal T2 to which a commercial AC voltage of 100V is supplied. The ion generating element 90b is applied with the voltage boosted by the boosting circuit 90a to generate ions.
　イオン発生素子９０ｂは放電電極９１ａ，９２ａと誘導電極９１ｂ，９２ｂとを備えている。図４に示すように誘導電極９１ｂ，９２ｂはイオン発生器９の一面に開口する放出孔に沿って環状に配される板電極により形成される。放電電極９１ａ，９２ａは誘導電極９１ｂ，９２ｂと同心の針電極により形成される。このイオン発生器９は昇圧回路９０ａ（図４参照）において昇圧された高電圧を放電電極９１ａ，９２ａと誘導電極９１ｂ，９２ｂとの間に印加して放電するように構成してある。 The ion generating element 90b includes discharge electrodes 91a and 92a and induction electrodes 91b and 92b. As shown in FIG. 4, the induction electrodes 91 b and 92 b are formed by plate electrodes arranged in a ring shape along an emission hole opened on one surface of the ion generator 9. The discharge electrodes 91a and 92a are formed by needle electrodes concentric with the induction electrodes 91b and 92b. The ion generator 9 is configured to apply and discharge a high voltage boosted by a booster circuit 90a (see FIG. 4) between the discharge electrodes 91a and 92a and the induction electrodes 91b and 92b.
　イオン発生素子９０ｂは空気中の水分を放電によりイオン化することにより、プラスイオンとしてのＨ＋（Ｈ２Ｏ）ｍ（ｍは任意の自然数）と、マイナスイオンとしてのＯ２ －（Ｈ２Ｏ）ｎ（ｎは任意の自然数）とを発生する。両方のイオンが空気中に送出される場合には、これらのイオンが空気中の浮遊細菌やウイルスの表面に取り付く。そして、これらが化学反応することにより、活性種である過酸化水素（Ｈ２Ｏ２）及び／又は水酸基ラジカル（・ＯＨ）が生成され、空気中の浮遊細菌や浮遊ウイルス等を殺菌または不活化することができる。 The ion generating element 90b ionizes moisture in the air by discharge, thereby generating H + (H 2 O) m (m is an arbitrary natural number) as positive ions and O 2 − (H 2 O) as negative ions. n (n is an arbitrary natural number). If both ions are delivered into the air, they will attach to the surface of airborne bacteria and viruses. These chemical reactions generate hydrogen peroxide (H 2 O 2 ) and / or hydroxyl radicals (.OH), which are active species, to sterilize or inactivate airborne bacteria and airborne viruses. can do.
　イオン発生器９はイオン発生室３９内に前キャビネット６から内側に突設する取付部（不図示）にイオンの放出孔を下方に向けて取り付けられている。前述のように、イオン発生器９の放電電極９１ａ，９２ａには高圧電気が印加されるので、取扱いの安全上外殻をなす部分との間に所定の距離を確保することが要求される。即ち、イオン発生室３９の内部に放電電極９１ａ，９２ａから所定の距離を確保した空間を形成することが要求される。本実施形態では高圧機器に要求される安全距離を考慮してこの距離を３０ｍｍ以上としている。 The ion generator 9 is attached to an attachment portion (not shown) protruding inward from the front cabinet 6 in the ion generation chamber 39 with the ion emission hole facing downward. As described above, since high-voltage electricity is applied to the discharge electrodes 91a and 92a of the ion generator 9, it is required to secure a predetermined distance from the portion forming the outer shell for safety of handling. That is, it is required to form a space that secures a predetermined distance from the discharge electrodes 91 a and 92 a in the ion generation chamber 39. In the present embodiment, this distance is set to 30 mm or more in consideration of the safety distance required for the high-voltage equipment.
　具体的には、後キャビネット３０の壁体３０ａが上方に行くほどファン４側に傾斜して延伸し、吸込口３９ａはイオン発生器９よりも下方に設けられる。このため、吸込口３９ａの開口最上部及び吹出口３９ｂの開口最上部が放電電極９１ａ，９２ａに対して外部から接触可能な最も近い位置にある。従って、吸込口３９ａの開口最上部と放電電極９１ａ，９２ａとの距離及び吹出口３９ｂの開口最上部と放電電極９１ａ，９２ａとの距離を３０ｍｍ以上にしている。 More specifically, the wall 30a of the rear cabinet 30 extends toward the fan 4 as it goes upward, and the suction port 39a is provided below the ion generator 9. For this reason, the uppermost opening part of the suction inlet 39a and the uppermost opening part of the blower outlet 39b are in the nearest positions where they can come into contact with the discharge electrodes 91a and 92a from the outside. Therefore, the distance between the uppermost opening of the suction port 39a and the discharge electrodes 91a and 92a and the distance between the uppermost opening of the outlet 39b and the discharge electrodes 91a and 92a are set to 30 mm or more.
　この距離は安全のためには大きいほどよいが、不要に大きいと前キャビネット６及び後キャビネット３０が肥大し、ひいては扇風機１０そのものが肥大化して扱いにくいものとなる。このため、各国の工業会の安全基準等を基準として前キャビネット６及び後キャビネット３０があまり大きくならないように決定されるのがよい。 This distance is preferably as large as possible for safety, but if it is unnecessarily large, the front cabinet 6 and the rear cabinet 30 will be enlarged, and the fan 10 itself will become enlarged and difficult to handle. For this reason, it is preferable that the front cabinet 6 and the rear cabinet 30 are determined so as not to be too large based on the safety standards of industrial associations in each country.
　吸込口３９ａ，吹出口３９ｂ以外の部分は樹脂製の壁体３０ａと前キャビネット６が覆っているために安全上の問題はない。また、イオン発生器９の下方に配されるモータ３１を構成する金属部分にイオン発生器９が発生したイオンが吸収される虞れがある。しかしながら、仕切り部３０ｂによってイオン発生室３９とモータ３１とを仕切ることにより、イオンの吸収を防止することができる。 Since the resin wall 30a and the front cabinet 6 cover portions other than the suction port 39a and the air outlet 39b, there is no safety problem. In addition, there is a possibility that ions generated by the ion generator 9 may be absorbed by a metal portion constituting the motor 31 disposed below the ion generator 9. However, the ion generation chamber 39 and the motor 31 are partitioned by the partition portion 30b, so that ion absorption can be prevented.
　図６は扇風機１０の制御ブロックを示す。基台１には各部を制御する制御装置５０が設置される。制御装置５０には運転スイッチ５２、運転モード切替スイッチ５３、風量スイッチ５４、タイマースイッチ５５、モータ３１、イオン発生器９、表示部５６、報知部５７が接続される。また、制御装置には計時を行う計時部５１が設けられる。 FIG. 6 shows a control block of the electric fan 10. A control device 50 for controlling each part is installed on the base 1. An operation switch 52, an operation mode switch 53, an air volume switch 54, a timer switch 55, a motor 31, an ion generator 9, a display unit 56, and a notification unit 57 are connected to the control device 50. In addition, the control device is provided with a timer unit 51 that performs timing.
　運転スイッチ５２は機器への電源の入切りを行う。運転モード切替スイッチ５３はイオン発生器９の運転要否を選択する。風量スイッチ５４は風量を選択する。タイマースイッチ５５はタイマー運転を選択する。表示部５６は各操作の結果を表示する。報知部５７は使用者に操作結果を報知する。 The operation switch 52 turns on / off the power to the equipment. The operation mode changeover switch 53 selects whether or not the ion generator 9 is to be operated. The air volume switch 54 selects the air volume. The timer switch 55 selects timer operation. The display unit 56 displays the result of each operation. The notification unit 57 notifies the user of the operation result.
　以上のように構成された扇風機１０において、運転スイッチ５２をオンにすると、モータ３１に電力が供給されてモータ３１が回転し、モータ３１の出力軸３２が一体的に回転する。この出力軸３２の回転に伴って、出力軸３２にファンナット５により固定されたファン４が一体的に回転する。このファン４の回転に伴いファンガード後部体７２からファンガード前部体７１に向けて流れる送風流路が生じる。 In the electric fan 10 configured as described above, when the operation switch 52 is turned on, electric power is supplied to the motor 31, the motor 31 rotates, and the output shaft 32 of the motor 31 rotates integrally. As the output shaft 32 rotates, the fan 4 fixed to the output shaft 32 by the fan nut 5 rotates integrally. Along with the rotation of the fan 4, an air flow path that flows from the fan guard rear body 72 toward the fan guard front body 71 is generated.
　また、運転モード切替スイッチ５３でイオン発生器９の運転を選択すると、イオン発生器９にも電力が供給され、プラスイオン及びマイナスイオンが発生する。発生したプラスイオン及びマイナスイオンは、イオン発生器９の放出孔から外部へ放出され、ファン４の回転により生じた送風によってファンガード前部体７１を通過して室内に放散される。 Further, when the operation of the ion generator 9 is selected by the operation mode changeover switch 53, power is also supplied to the ion generator 9, and positive ions and negative ions are generated. The generated positive ions and negative ions are discharged to the outside from the discharge hole of the ion generator 9, and are diffused indoors through the fan guard front body 71 by the air generated by the rotation of the fan 4.
　本実施形態は扇風機であって、扇風機１０の羽根４には所謂プロペラファンが採用されている。プロペラファンは、構成する翼の数に対応してファンの回転軸を中心とするらせん気流を発生させ、らせん気流は回転しながら下流方向に進行するに伴って軸の外側に向かって拡散しながら送出されるという性質を有する。 This embodiment is an electric fan, and a so-called propeller fan is adopted for the blade 4 of the electric fan 10. The propeller fan generates a spiral air flow around the rotation axis of the fan corresponding to the number of wings constituting the fan, and the spiral air flow rotates while diffusing toward the outside of the shaft as it travels downstream. It has the property of being sent out.
　このため、イオン発生室３９の吸込口３９ａから吸い込まれた気流が、イオン発生器９のイオンの放出孔を包み込むように流れるとともに、後キャビネット３０の仕切り部３０ｂとほぼ平行に流通する。そして、イオン発生器９で発生するイオンを含んだ気流が吹出口３９ｂから流出し、ファン４に引き込まれて前方に送出される。この時、図３に示すようにファン４の回転軸に近い部分の気流Ａは、ほぼ直進して前方に達するのに対して、回転軸から遠い部分の気流Ｂは直進せずに室内に拡散する。 For this reason, the airflow sucked from the suction port 39a of the ion generation chamber 39 flows so as to wrap around the ion discharge hole of the ion generator 9, and flows almost in parallel with the partition portion 30b of the rear cabinet 30. And the airflow containing the ion which generate | occur | produces with the ion generator 9 flows out from the blower outlet 39b, is drawn in by the fan 4, and is sent ahead. At this time, as shown in FIG. 3, the airflow A in the portion near the rotation axis of the fan 4 travels substantially straight and reaches the front, whereas the airflow B in the portion far from the rotation axis does not travel straight and diffuses into the room. To do.
　扇風機１０の前方側より操作を行う使用者は、当然扇風機１０前方に居る。そのため、本実施形態ではイオン発生器９の放電電極９１ａ，９２ａの位置（イオン発生器９からイオンが発生する位置）が、ファン４の羽根４１の半径長さの半分（中間部）となるようにした。これにより、使用者に直接届けるべきイオンと室内に広く拡散させて室内環境を改善するイオンの量を好ましいバランスで調整することができる。なお、イオン発生器９の放電電極９１ａ，９２ａの位置を、羽根４１の半径の半分（１／２）としたが、これに近い位置であればよく、その前後に多少ずれても同様の効果を奏する。そのずれの範囲は、５％程度であれば十分な効果を期待できる。 The user who operates from the front side of the fan 10 is naturally in front of the fan 10. Therefore, in the present embodiment, the positions of the discharge electrodes 91 a and 92 a of the ion generator 9 (positions where ions are generated from the ion generator 9) are half the intermediate length of the radial length of the blade 41 of the fan 4. I made it. Thereby, the amount of ions that should be directly delivered to the user and ions that diffuse widely in the room and improve the indoor environment can be adjusted in a favorable balance. Although the positions of the discharge electrodes 91a and 92a of the ion generator 9 are set to half the radius (1/2) of the blade 41, the positions may be close to this, and the same effect can be obtained even if they are slightly deviated before and after. Play. If the deviation range is about 5%, a sufficient effect can be expected.
　このように構成された扇風機１０においては、プラスイオン及びマイナスイオンにより空気中に浮遊するインフルエンザウイルス等のウイルス、病原菌を死滅又は不活性化させることによって、ウイルス及び病原菌から人体を守ることができる。 In the electric fan 10 configured in this way, the human body can be protected from viruses and pathogens by killing or inactivating viruses and pathogens such as influenza virus floating in the air by positive ions and negative ions.
　なお、本実施形態ではイオン発生器を正イオンおよび負イオンを発生するものとしたが、空気中の浮遊菌の殺菌等を意図しない場合には、負イオン発生器であっても構わない。この場合には、従来から気分を爽快にする効果が得られるとされている。 In this embodiment, the ion generator generates positive ions and negative ions. However, in the case where sterilization of airborne bacteria in the air is not intended, a negative ion generator may be used. In this case, it is conventionally said that an effect of refreshing the mood can be obtained.
　以上説明したように、本実施形態のイオン発生機能を備える扇風機１０は、モータ３１を備える駆動部３を収容するための後キャビネット３０の上部を上方へと隆起（延伸）させように形成しており、その隆起させた部分にイオン発生器９を内装させるイオン発生室３９（収納部）を設けている。 As described above, the electric fan 10 having the ion generation function of the present embodiment is formed so that the upper part of the rear cabinet 30 for housing the drive unit 3 including the motor 31 is raised (stretched) upward. In addition, an ion generation chamber 39 (housing portion) in which the ion generator 9 is housed is provided in the raised portion.
　また、本実施形態においては、取っ手６０を形成するための後キャビネット３０にイオン発生器９を内装するためのイオン発生室３９（収納部）を設けるようにしている。 Further, in the present embodiment, an ion generation chamber 39 (accommodating portion) for installing the ion generator 9 is provided in the rear cabinet 30 for forming the handle 60.
　以上のようにすることで、形成されたイオン発生室３９にイオン発生器９を配置できる。そのため、イオン発生器９がイオン発生室３９に設けられるため、使用者が触れること極力避けることができ、安全性を同時に確保できる。また、モータ３１を収容するキャビネット（６，３０）を上方へと隆起させるとともに延伸させ、さらにその隆起部を利用して取っ手６０を設けることで、イオン発生室３９を形成できると同時に、持ち運び用の取っ手６０を合わせて形成できる。従って、扇風機１０本体が確保する領域内を有効活用でき、扇風機１０本体が大型化することもなく、外観の美しさを保つことが出来る。 As described above, the ion generator 9 can be disposed in the formed ion generation chamber 39. Therefore, since the ion generator 9 is provided in the ion generation chamber 39, it can avoid that a user touches as much as possible, and can ensure safety simultaneously. Further, the cabinet (6, 30) for housing the motor 31 is raised and extended upward, and the handle 60 is provided by using the raised portion, so that the ion generation chamber 39 can be formed and at the same time portable. Can be formed together. Therefore, the area secured by the main body of the electric fan 10 can be effectively used, and the appearance of the electric fan 10 can be maintained without increasing its size.
　さらに、キャビネット（６、３０）を隆起させることで、イオン発生器９のイオン発生位置をモータ３１により回転するファン４の羽根４１の半径のほぼ１／２の位置に容易に配置できる。つまり、イオンの発生位置を羽根４１の半径の中間部に配置するための特別の部材等を設けることなく、キャビネットの隆起の程度を適宜設定することでイオン発生位置を目的の位置に簡単に調整できる。 Furthermore, by raising the cabinet (6, 30), the ion generation position of the ion generator 9 can be easily arranged at a position approximately half the radius of the blade 41 of the fan 4 that is rotated by the motor 31. In other words, the ion generation position can be easily adjusted to the target position by appropriately setting the degree of bulging of the cabinet without providing a special member or the like for disposing the ion generation position in the middle portion of the blade 41 radius. it can.
　さらに、モータ３１を収容するキャビネットを隆起させてイオン発生室３９を形成するため、ファン４の風上にイオン発生器９を配置できる。このとき、イオン発生室３９に吸込口３９ａ、吹出口３９ｂを形成すれば、風上で発生したイオンを効率よくファン４を介して前方へと放散させることができ、放散させるための特別な構成を必要としなくなる。 Further, since the ion generation chamber 39 is formed by raising the cabinet that houses the motor 31, the ion generator 9 can be disposed on the windward side of the fan 4. At this time, if the inlet 39a and the outlet 39b are formed in the ion generation chamber 39, ions generated on the windward can be efficiently dissipated forward via the fan 4, and a special configuration for dissipating the ions is generated. Is no longer required.
　以上のべたように、簡素な構成により、高電圧を印加するイオン発生器９の収納部を扇風機１０に備えることができる。また、扇風機１０が元から有している外殻部にイオン発生器９の収納部を一体に形成したので、使用者が安全に取り扱えるとともに、イオン発生部が大型化することを抑制して外観上も美しくすることができる。 As described above, the electric fan 10 can be provided with a storage portion for the ion generator 9 that applies a high voltage with a simple configuration. Moreover, since the storage part of the ion generator 9 was integrally formed in the outer shell part which the electric fan 10 originally has, while being able to handle a user safely, it suppresses that an ion generation part enlarges and it is an external appearance. The top can also be beautiful.
　本発明によれば、扇風機を例にイオン発生機能を備える送風機を説明したが、その他室内の空気を循環させる等のサーキュレータ、また換気扇等にも適用できる。換気扇としては、室外の空気を室内に取り入れる際に、イオン発生器を動作させ室内に放散させることができる。 According to the present invention, a blower having an ion generation function has been described taking a fan as an example, but it can also be applied to a circulator for circulating indoor air, a ventilation fan, and the like. As a ventilation fan, when taking in outdoor air indoors, an ion generator can be operated and diffused indoors.
