　特許文献１のドライヤーによれば、従来のニクロム線ヒーターを熱源とするドライヤーに比べて消費電力を低減できる。しかし、使用中の異常な温度上昇に対処する構成は開示されていない。 According to the dryer of Patent Document 1, it is possible to reduce power consumption as compared with a conventional dryer using a nichrome wire heater as a heat source. However, there is no disclosure of a structure that copes with an abnormal temperature rise during use.
　本発明の目的は、異常な温度上昇に対して確実に対処できる光照射装置を提供することにある。 An object of the present invention is to provide a light irradiation device that can reliably handle an abnormal temperature rise.
　本発明の光照射装置は、発光構造４と、同構造４を収容するケース構造１とを備えている。ケース構造１の内部に導風路９が形成され、導風路９の前端に吹出口１１が開口されている。導風路９の内部に、吹出口１１の側から順に発光構造４と、風を発光構造４および吹出口１１へ向かって送給する送風構造３とが配置されている。送風構造３から送給される風を受けることができ、かつ発光構造４から照射される光を受けることができる位置に、発光構造４の駆動を制御する温度センサー９８が設けられている（図３参照）。 The light irradiation device of the present invention includes a light emitting structure 4 and a case structure 1 that accommodates the structure 4. An air guide passage 9 is formed inside the case structure 1, and an air outlet 11 is opened at the front end of the air guide passage 9. Inside the air guide path 9, the light emitting structure 4 and the air blowing structure 3 for sending the wind toward the light emitting structure 4 and the air outlet 11 are arranged in this order from the air outlet 11 side. A temperature sensor 98 for controlling the drive of the light emitting structure 4 is provided at a position where the air sent from the air blowing structure 3 can be received and the light emitted from the light emitting structure 4 can be received (FIG. 3).
　発光構造４が、光源２８と、前部に照射開口を有し、光源２８から照射された光を照射開口へ向かって反射案内するリフレクタ２９とを備えている。発光構造４の照射開口が吹出口１１に臨むように発光構造４が配置されている。吹出口１１と発光構造４の照射開口との間に温度センサー９８が設けられている。 The light emitting structure 4 includes a light source 28 and a reflector 29 that has an irradiation opening in the front part and that reflects and guides the light emitted from the light source 28 toward the irradiation opening. The light emitting structure 4 is arranged so that the irradiation opening of the light emitting structure 4 faces the air outlet 11. A temperature sensor 98 is provided between the air outlet 11 and the irradiation opening of the light emitting structure 4.
　温度センサー９８がケース構造１に取り付けられている。温度センサー９８が取り付けられているケース構造１が、発光構造４の照射開口に近づく向きに傾斜している。 The temperature sensor 98 is attached to the case structure 1. The case structure 1 to which the temperature sensor 98 is attached is inclined so as to approach the irradiation opening of the light emitting structure 4.
　発光構造４とケース構造１との間に仕切壁１３０が設けられている。 A partition wall 130 is provided between the light emitting structure 4 and the case structure 1.
　仕切壁１３０は、風の送風方向に沿って設けられている。仕切壁１３０の一端が発光構造４よりも前方に突出している。 The partition wall 130 is provided along the wind blowing direction. One end of the partition wall 130 projects forward of the light emitting structure 4.
　仕切壁１３０の一端が発光構造４の照射開口に近づく向きに傾斜している。 -One end of the partition wall 130 is inclined so as to approach the irradiation opening of the light emitting structure 4.
　本発明の光照射装置においては、送風構造３から送給される風を受けることができ、かつ発光構造４から照射される光を受けることができる位置に、発光構造４の駆動を制御する温度センサー９８が設けられている。通常の駆動時には、温度センサー９８が、発光構造４から照射される赤外線（熱線）を含む光を受けての温度上昇が送風構造３から送給される風による冷却により抑制されて所定範囲の温度を維持しているが、例えば吹出口１１がタオルなどで覆われた際は風量が減少し、これにより風による冷却ができなくなれば発光構造４は駆動を続けているので温度バランスが崩れて温度センサー９８が同センサー９８を作動させる温度まで上昇することになる。したがって、異常な使用状態となったときには確実に温度センサー９８を作動させることができ、これにより発光構造４の駆動を停止または出力を低下させてケース構造１内の温度上昇を抑制できる。 In the light irradiation device of the present invention, the temperature for controlling the drive of the light emitting structure 4 is at a position where the air sent from the air blowing structure 3 can be received and the light emitted from the light emitting structure 4 can be received. A sensor 98 is provided. At the time of normal driving, the temperature sensor 98 suppresses an increase in temperature upon receiving light including infrared rays (heat rays) emitted from the light emitting structure 4 and is suppressed by cooling by the air blown from the air blowing structure 3, and the temperature within a predetermined range. However, for example, when the air outlet 11 is covered with a towel or the like, the air volume decreases, and if cooling by the wind becomes impossible, the light emitting structure 4 continues to be driven and the temperature balance is lost, resulting in The temperature of the sensor 98 will rise to the temperature at which it operates. Therefore, the temperature sensor 98 can be reliably operated in an abnormal use state, whereby the driving of the light emitting structure 4 can be stopped or the output can be reduced to suppress the temperature rise in the case structure 1.
　吹出口１１と発光構造４の照射開口との間に温度センサー９８が設けられている。これにより、複雑な構成を採らなくても温度センサー９８が送風構造３から送給される風を受けることができ、かつ発光構造４から照射される光を受けることができる。 A temperature sensor 98 is provided between the outlet 11 and the irradiation opening of the light emitting structure 4. Accordingly, the temperature sensor 98 can receive the air blown from the air blowing structure 3 and can receive the light emitted from the light emitting structure 4 without adopting a complicated configuration.
　温度センサー９８が取り付けられているケース構造１が、発光構造４の照射開口に近づく向きに傾斜している。これにより、温度センサー９８の固定を安定させた状態で、温度センサー９８に対して送風構造３から送給される風を接触させることができるとともに発光構造４からの光を照射することができる。 The case structure 1 to which the temperature sensor 98 is attached is inclined toward the irradiation opening of the light emitting structure 4. Thereby, in a state where the temperature sensor 98 is stably fixed, the air blown from the air blowing structure 3 can be brought into contact with the temperature sensor 98, and the light from the light emitting structure 4 can be emitted.
　発光構造４とケース構造１との間に仕切壁１３０が設けられている。これにより、送風構造３から送給される風が仕切壁１３０により分断される。分断された風のうち発光構造４に臨む空間を通過する風は、発光構造４自体の熱により加熱されて温度上昇する。一方、分断された風のうち発光構造４に臨む空間とは仕切壁１３０を挟んで反対側の空間を通過する風は、発光構造４からの受熱量は小さく、発光構造４に臨む空間を通過する風よりも温度は低い。したがって、温度センサー９８を比較的温度の低い風により冷却できるので、温度センサー９８が光を受けつつもそれ自体の温度をより低いところでキープすることができる。これによって、作動温度が低い温度センサー９８を使用することができ、何らかの原因で風量が低下した異常状態のとき同センサー９８を異常から早い段階で作動させることができる。 A partition wall 130 is provided between the light emitting structure 4 and the case structure 1. Thereby, the air sent from the air blowing structure 3 is divided by the partition wall 130. Of the divided winds, the wind passing through the space facing the light emitting structure 4 is heated by the heat of the light emitting structure 4 itself and its temperature rises. On the other hand, among the divided winds, the wind passing through the space on the opposite side of the space facing the light emitting structure 4 with the partition wall 130 therebetween has a small amount of heat received from the light emitting structure 4 and passes through the space facing the light emitting structure 4. The temperature is lower than the wind. Therefore, since the temperature sensor 98 can be cooled by the wind having a relatively low temperature, it is possible to keep the temperature of the temperature sensor 98 at a lower temperature while receiving the light. As a result, the temperature sensor 98 having a low operating temperature can be used, and the sensor 98 can be operated at an early stage from an abnormality in an abnormal state in which the air volume is lowered for some reason.
　仕切壁１３０の一端が発光構造４よりも前方に突出している。これにより、温度センサー９８に、発光構造４に臨む空間とは仕切壁１３０を挟んで反対側の空間を通過する比較的温度の低い風を確実に接触させることができる。 -One end of the partition wall 130 projects forward of the light emitting structure 4. Thus, the temperature sensor 98 can be reliably brought into contact with the air having a relatively low temperature passing through the space on the opposite side of the space facing the light emitting structure 4 with the partition wall 130 interposed therebetween.
　仕切壁１３０の一端が発光構造４の照射開口に近づく向きに傾斜している。これにより、温度センサー９８に、発光構造４に臨む空間とは仕切壁１３０を挟んで反対側の空間を通過する比較的温度の低い風を十分な量接触させることができる。 -One end of the partition wall 130 is inclined so as to approach the irradiation opening of the light emitting structure 4. As a result, the temperature sensor 98 can be brought into contact with a sufficient amount of relatively low temperature air passing through the space on the opposite side of the space facing the light emitting structure 4 with the partition wall 130 interposed therebetween.

On the inner surface of the front part of the outer casing 8, a case seat 8a for receiving the contact part 5a is formed so as to project in a C shape. Further, engagement walls 7c that engage with the engagement grooves 5c are formed at four circumferential positions on the outer surface of the front portion of the air guide tube 7. As shown in FIGS. 3 and 4, at the front part of the air guide tube 7 facing the outlet 11, the inner wall of the front conduit-like air guide tube 7 and the blow-out case 5 form an indented constriction. The portion 35 is formed, and the blowout grill 25 is arranged on the inner surface of the constricted portion 35.
　吹出ケース５を外装筒８の前方から組み付けて、接当部５ａがケース受座８ａで受止め支持された状態で、吹出ケース５を回転操作することにより、係合脚５ｂの係合溝５ｃと係合壁７ｃとが互いに係合して、外装筒８と吹出ケース５と風導筒７の３者を一体化している。上記のように吹出ケース５は、４個の係合脚５ｂと、係合脚５ｂに対応して風導筒７の前部外面に設けた４個の係合壁７ｃとで構成される吹出口連結構造によって風導筒７にバヨネット連結されており、吹出ケース５の下端を外装筒８の周面側からねじ込んだビス１９（図３参照）で締結することにより、外装筒８と一体化されている。 By assembling the blow-out case 5 from the front of the outer casing 8 and rotating the blow-out case 5 in a state where the contact portion 5a is received and supported by the case receiving seat 8a, the engagement groove 5c of the engagement leg 5b is formed. The engagement wall 7c is engaged with each other to integrate the exterior cylinder 8, the blowout case 5, and the air guide cylinder 7 into one body. As described above, the blow-out case 5 is composed of four engagement legs 5b and four engagement walls 7c provided on the outer surface of the front portion of the air guide tube 7 corresponding to the engagement legs 5b. The structure is connected to the air guide tube 7 by a bayonet, and the lower end of the blowout case 5 is fastened with a screw 19 (see FIG. 3) screwed from the peripheral surface side of the outer case 8 to be integrated with the outer case 8. There is.
　補助吹出ケース６は花弁状のリング体からなり、赤外線および乾燥風の通過を許す円形の通口９６を備えており、通口９６の下側に乾燥風の一部とマイナスイオンの通過を許すイオン通口９７が横長長円状に形成されている。通口９６の直径は、後述する照射開口の直径より僅かに大きく設定されている。以上のように構成した吹出口１１は、乾燥風の吹出口として機能する以外に、ハロゲンランプ２８から照射される赤外線（熱線）をユーザーの毛髪へ向けて照射する照射口を兼ねている。 The auxiliary blow-out case 6 is made of a petal-shaped ring body, and is provided with a circular through hole 96 that allows infrared rays and dry air to pass therethrough. A part of the dry air and negative ions are allowed to pass under the through hole 96. The ion passage 97 is formed in a horizontally elongated oval shape. The diameter of the passage 96 is set to be slightly larger than the diameter of the irradiation opening described later. The air outlet 11 configured as described above functions not only as an outlet for dry air but also as an irradiation opening for irradiating infrared rays (heat rays) emitted from the halogen lamp 28 toward the user's hair.
　図３および図４において光源ユニット４は、ハロゲンランプ２８と、リフレクタ２９と、リフレクタ２９の前面の照射開口に装着されるフィルタ３０を備えた１個のユニット部品からなる。ハロゲンランプ２８は、発光部（フィラメント）３６と不活性ガス及びハロゲンガスなどを封入した前後に長いバルブ３１とハウジング３２を備えており、ハウジング３２のプラグ３３をソケット（支持台）３４に差込み装着することにより、ソケット３４で固定支持されている。ソケット３４は後述する光源台４５に締結固定されている。ハロゲンランプ２８を点灯すると、バルブ３１の発光部３６から可視光と赤外光が照射される。フィルタ３０は、赤外光は透過するが可視光の透過を阻むように構成されており、これにより、ユーザーはハロゲンランプ２８の眩しさを感じることはない。なお、可視光の透過を阻むとは、完全に可視光を遮ることを意味するものではなく、可視光を減衰することを含む概念である。もちろん、可視光を完全に遮って赤外光のみが透過可能なものも含む。 In FIGS. 3 and 4, the light source unit 4 is composed of one unit component including a halogen lamp 28, a reflector 29, and a filter 30 attached to the irradiation opening on the front surface of the reflector 29. The halogen lamp 28 includes a light emitting part (filament) 36, a long bulb 31 and a housing 32 before and after enclosing an inert gas and a halogen gas, and a plug 33 of the housing 32 is inserted into a socket (support base) 34 to be mounted. By doing so, it is fixedly supported by the socket 34. The socket 34 is fastened and fixed to a light source base 45 described later. When the halogen lamp 28 is turned on, visible light and infrared light are emitted from the light emitting portion 36 of the bulb 31. The filter 30 is configured to transmit infrared light but block visible light, so that the user does not feel the glare of the halogen lamp 28. Note that blocking the transmission of visible light does not mean completely blocking visible light, but is a concept that includes attenuating visible light. Of course, it also includes one that completely blocks visible light and allows only infrared light to pass through.
　リフレクタ２９は、前リフレクタ３７と後リフレクタ３８を接合して構成されている。図７に示すように前リフレクタ３７は、左右に分割形成された一対の分割体３７ａ・３７ｂを接合して構成されている。これら分割体３７ａ・３７ｂはアルミニウムなどの金属製のプレス成形品からなり、その内面には反射面が形成されている。反射面は、研磨加工や鏡面仕上げ加工などで形成することができ、必要があればメッキ処理を施すことができる。 The reflector 29 is configured by joining a front reflector 37 and a rear reflector 38. As shown in FIG. 7, the front reflector 37 is configured by joining a pair of split bodies 37a and 37b that are split left and right. Each of the divided bodies 37a and 37b is a press-molded product made of metal such as aluminum, and has a reflective surface formed on the inner surface thereof. The reflecting surface can be formed by polishing or mirror finishing, and can be plated if necessary.
　前リフレクタ３７の内面には、ハロゲンランプ２８から照射された光をフィルタ３０へ向かって前向きに反射案内する第１反射面３９と、ハロゲンランプ２８から照射された光を、第３反射面４３へ向かって後向きに反射案内する第２反射面４０とが設けられている。第２反射面４０は第１反射面３９に隣接する状態で形成されている。分割体３７ａ・３７ｂの前端内面にはフィルタ受座４１が形成されており、フィルタ受座４１の後周面には第２通気口４２が２個ずつ形成されている。第２通気口４２は、分割体３７ａ・３７ｂを接合した状態において、前リフレクタ３７の前端寄りの壁面に、スリット状の開口として全周にわたって形成されている。前リフレクタ３７は、１個の反射筒で構成してあってもよい。その場合にはアルミニウムなどの金属を素材とするダイキャスト成形品で構成することができる。 On the inner surface of the front reflector 37, the first reflection surface 39 that guides the light emitted from the halogen lamp 28 forward toward the filter 30 and the light emitted from the halogen lamp 28 to the third reflection surface 43. A second reflecting surface 40 that guides and guides backwards is provided. The second reflecting surface 40 is formed so as to be adjacent to the first reflecting surface 39. A filter seat 41 is formed on the inner surface of the front ends of the divided bodies 37a and 37b, and two second ventilation ports 42 are formed on the rear peripheral surface of the filter seat 41. The second ventilation port 42 is formed as a slit-shaped opening over the entire circumference on the wall surface near the front end of the front reflector 37 in the state where the divided bodies 37a and 37b are joined. The front reflector 37 may be composed of one reflecting cylinder. In that case, it can be constituted by a die-cast molded product made of a metal such as aluminum.
　後リフレクタ３８は、アルミニウムなどの金属を素材とするダイキャスト成形品からなり、その前面にハロゲンランプ２８から照射された光および第２反射面４０で反射案内された光を、フィルタ３０へ向かって前向きに反射案内する凹面鏡状の第３反射面４３が設けられている。反射面は研磨加工や、鏡面仕上げ加工などで形成することができ、必要があればメッキ処理を施して形成することができる。第３反射面４３の後側には、ハロゲンランプ２８を支持する光源支持構造が設けられている。後リフレクタ３８後部には、後述する光源台４５と導風壁４６が一体形成されている。 The rear reflector 38 is made of a die-cast molded product made of a metal such as aluminum, and the front surface of the rear reflector 38 is irradiated with the light emitted from the halogen lamp 28 and the light reflected and guided by the second reflecting surface 40 toward the filter 30. A concave mirror-shaped third reflecting surface 43 that guides and guides forward is provided. The reflecting surface can be formed by polishing, mirror finishing, or the like, and can be formed by plating if necessary. A light source support structure that supports the halogen lamp 28 is provided on the rear side of the third reflecting surface 43. A light source base 45 and a wind guide wall 46, which will be described later, are integrally formed on the rear portion of the rear reflector 38.
　光源支持構造は、ハロゲンランプ２８を支持する４個のボスからなる光源台４５と、光源台４５の周囲を囲む、６角筒状の導風壁４６とを備えており、先に説明したソケット３４が各光源台４５に４個の金属製のビス（締結具）４７により配線基板４９とともに共締め固定されている。第３反射面４３の中央には、乾燥風をリフレクタ２９の内部に導入するための第１通気口４８が形成されている。配線基板４９は、ハロゲンランプ２８に電力を供給するリード線や、ファンモータ２に電力を供給するリード線などを、いったんまとめて振り分けるために設けられている。導風壁４６とハロゲンランプ２８の間は光源冷却通路とされており、第１通気口４８に連通している。光源台４５に固定した配線基板４９は、第１通気口４８から漏れ出た光が吸込口１０側へ放射されるのを阻止するための遮光板を兼ねている。ソケット３４の材質は、セラミックである。 The light source support structure includes a light source base 45 composed of four bosses that support the halogen lamp 28, and a hexagonal tubular air guide wall 46 surrounding the light source base 45, and the socket described above. 34 is fixed to each light source base 45 together with four wiring screws (fasteners) 47 together with the wiring board 49. A first ventilation port 48 for introducing dry air into the reflector 29 is formed in the center of the third reflecting surface 43. The wiring board 49 is provided for collectively allocating the lead wires for supplying electric power to the halogen lamp 28, the lead wires for supplying electric power to the fan motor 2, and the like. A light source cooling passage is provided between the air guide wall 46 and the halogen lamp 28 and communicates with the first ventilation port 48. The wiring board 49 fixed to the light source base 45 also serves as a light blocking plate for preventing the light leaking from the first ventilation port 48 from being emitted to the suction port 10 side. The material of the socket 34 is ceramic.
　図３において、光源ユニット４より前側の風導筒７の上壁部分には、温度センサー９８が設けられている。具体的には、左右に分割された一対の半割体７ａ・７ｂの間の接合面に挟持されて固定されるセンサーホルダー１３１を備え、センサーホルダー１３１に含まれる同ホルダー１３１と一体の断面コ字状のホルダー部１３２に温度センサー９８は支持固定される。つまり、温度センサー９８は、センサーホルダー１３１を介して風導筒７、すなわちケース構造１に取り付けられている。ホルダー部１３２に対する温度センサー９８の固定は、ホルダー部１３２と温度センサー９８とを接着する接着剤と、ホルダー部１３２と温度センサー９８を囲繞する状態で熱を加えて締め付ける熱収縮チューブにより行う。 In FIG. 3, a temperature sensor 98 is provided on the upper wall portion of the air guide tube 7 on the front side of the light source unit 4. Specifically, the sensor holder 131 is sandwiched and fixed to the joining surface between the pair of left and right half- split bodies 7a and 7b, and the sectional holder integrated with the holder 131 included in the sensor holder 131 is provided. The temperature sensor 98 is supported and fixed to the character-shaped holder portion 132. That is, the temperature sensor 98 is attached to the air guide tube 7, that is, the case structure 1 via the sensor holder 131. The temperature sensor 98 is fixed to the holder portion 132 with an adhesive that bonds the holder portion 132 and the temperature sensor 98, and a heat-shrinkable tube that heats and tightens the holder portion 132 and the temperature sensor 98 while surrounding them.
　前述したように風導筒７を光源ユニット４と吹出口１１の間で前すぼまり状に形成しているので、風導筒７、すなわちケース構造１が、光源ユニット４の照射開口に近づく向きに傾斜している。温度センサー９８は、吹出口１１と光源ユニット４の照射開口との間であって、光源ユニット４の照射開口に近づく向きに傾斜している剛性の高い風導筒７に取り付けられているので、温度センサー９８の固定を安定させた状態で、温度センサー９８に対して発光構造４からの光を確実に照射することができる。これにより、温度センサー９８の固定を安定させた状態で、温度センサー９８に対して送風構造３から送給される風を接触させることができるとともに発光構造４からの光を照射することができる。ちなみに、傾斜していないケース構造であれば発光構造４からの光を温度センサー９８に確実に照射させるためにはセンサーホルダー１３１をかなり長くする必要があり、温度センサー９８の固定が不安定となりやすい。 As described above, since the air guide tube 7 is formed in the front concavity shape between the light source unit 4 and the air outlet 11, the air guide tube 7, that is, the case structure 1 approaches the irradiation opening of the light source unit 4. It is tilted in the direction. Since the temperature sensor 98 is attached between the air outlet 11 and the irradiation opening of the light source unit 4 and is attached to the highly rigid air guide tube 7 that is inclined toward the irradiation opening of the light source unit 4, It is possible to reliably irradiate the temperature sensor 98 with light from the light emitting structure 4 in a state where the temperature sensor 98 is stably fixed. Thereby, in a state where the temperature sensor 98 is stably fixed, the air blown from the air blowing structure 3 can be brought into contact with the temperature sensor 98, and the light from the light emitting structure 4 can be emitted. By the way, if the case structure is not inclined, the sensor holder 131 needs to be considerably long in order to reliably irradiate the temperature sensor 98 with the light from the light emitting structure 4, and the fixation of the temperature sensor 98 tends to be unstable. ..
　温度センサー９８は、バイメタル式のサーモスタットからなり、光源ユニット４のハロゲンランプ２８に回路的に直列で接続されている。異常時に温度センサー９８が設定温度（本実施例では７０℃）になるとバイメタルの一方が他方から離れて回路が開状態となりハロゲンランプ２８へ供給される電流が遮断される。その後、異常状態が解消されると温度センサー９８は徐々に温度が低下し、所定の温度まで低下すればバイメタル同士が再び接触して導通状態に戻り、通常の使用が可能な状態となる。上述したように光源ユニット４の駆動を制御する温度センサー９８が吹出口１１と光源ユニット４の照射開口との間に設けられていることにより、複雑な構成を採らなくても温度センサー９８が送風ファン３から送給される風を受けることができ、かつ発光ユニット４から照射される光を受けることができる。通常の使用（駆動）時には、温度センサー９８が、発光ユニット４から照射される赤外線（熱線）を含む光を受けての温度上昇が送風ファン３から送給される風による冷却により抑制されて所定範囲の温度（本実施例では６０℃）を維持しているが、例えば吹出口１１がタオルなどで覆われた際は風量が減少し、これにより風による冷却ができなくなれば発光ユニット４は駆動を続けているので温度バランスが崩れて温度センサー９８が同センサー９８を作動させる温度（７０℃）まで上昇することになる。したがって、吹出口１１がタオルなどで覆われる、あるいは送風ファン３駆動用のファンモータ２がロックして駆動を停止するなどの異常な使用状態となったときには確実に温度センサー９８を作動させることができ、これにより発光ユニット４の駆動を停止させて風導筒７、すなわちケース構造１内の温度上昇を抑制できる。 The temperature sensor 98 is composed of a bimetal type thermostat and is connected in series to the halogen lamp 28 of the light source unit 4 in a circuit manner. When the temperature sensor 98 reaches the set temperature (70 ° C. in the present embodiment) at the time of abnormality, one of the bimetals separates from the other, the circuit is opened, and the current supplied to the halogen lamp 28 is cut off. After that, when the abnormal state is resolved, the temperature of the temperature sensor 98 gradually decreases, and when the temperature decreases to a predetermined temperature, the bimetals come into contact with each other again to return to the conductive state, and the normal use is possible. Since the temperature sensor 98 for controlling the driving of the light source unit 4 is provided between the outlet 11 and the irradiation opening of the light source unit 4 as described above, the temperature sensor 98 blows air even if a complicated configuration is not adopted. The wind sent from the fan 3 can be received, and the light emitted from the light emitting unit 4 can be received. During normal use (driving), the temperature sensor 98 receives the light including the infrared rays (heat rays) emitted from the light emitting unit 4 and the temperature rise is suppressed by cooling by the air blown from the blower fan 3, and the temperature rise is predetermined. The temperature in the range (60 ° C. in this embodiment) is maintained, but when the outlet 11 is covered with a towel or the like, the air flow rate decreases, and if the cooling by the wind becomes impossible, the light emitting unit 4 is driven. As the temperature continues to be lost, the temperature balance is lost and the temperature sensor 98 rises to the temperature (70 ° C.) at which the sensor 98 operates. Therefore, the temperature sensor 98 can be surely operated in an abnormal use state such as when the air outlet 11 is covered with a towel or the like, or the fan motor 2 for driving the blower fan 3 is locked to stop driving. As a result, the driving of the light emitting unit 4 can be stopped and the temperature rise in the air guide tube 7, that is, the case structure 1 can be suppressed.
　光源ユニット４は、ハロゲンランプ２８と、前部に照射開口を有し、ハロゲンランプ２８から照射された光を照射開口へ向かって反射案内するリフレクタ２９とを備えているが、図３に示すように光源ユニット４の照射開口が吹出口１１に臨むように光源ユニット４が配置されている。光源ユニット４と風導筒７、すなわちケース構造１との間には仕切壁１３０が設けられている。仕切壁１３０は、ステンレスなどの金属製の長方形状の平板からなり、その長手方向が風導筒７の軸方向（前後方向）と一致するように導風路９に配置されている。言い換えれば仕切壁１３０は、風の送風方向に沿って設けられている。また、仕切壁１３０は、光源ユニット４と風導筒７との間に配設される状態において仕切壁１３０の一端が光源ユニット４よりも前方に突出している状態となっている。この突出寸法は温度センサー９８の手前の近接する位置まで突出している。仕切壁１３０は、後述するばね受枠６４にリベット１３４にて固定されている。 The light source unit 4 includes a halogen lamp 28 and a reflector 29 that has an irradiation opening in the front part and that reflects and guides the light emitted from the halogen lamp 28 toward the irradiation opening, as shown in FIG. The light source unit 4 is arranged so that the irradiation opening of the light source unit 4 faces the air outlet 11. A partition wall 130 is provided between the light source unit 4 and the air guide tube 7, that is, the case structure 1. The partition wall 130 is made of a rectangular flat plate made of metal such as stainless steel, and is arranged in the air guide passage 9 so that its longitudinal direction coincides with the axial direction (front-back direction) of the air guide tube 7. In other words, the partition wall 130 is provided along the wind blowing direction. Further, the partition wall 130 is in a state in which one end of the partition wall 130 projects forward of the light source unit 4 in a state of being arranged between the light source unit 4 and the air guide tube 7. This projecting dimension projects to a position close to and in front of the temperature sensor 98. The partition wall 130 is fixed to the spring receiving frame 64 described later with rivets 134.
　このように光源ユニット４と風導筒７との間に仕切壁１３０が設けられていることにより、送風ファン３から送給される風が仕切壁１３０により分断される。分断された風のうち光源ユニット４に臨む空間を通過する風は、発熱している光源ユニット４との熱交換により温度上昇する。光源ユニット４に臨む空間を通過する風の温度は約６０℃である。一方、分断された風のうち発光構造４に臨む空間とは仕切壁１３０を挟んで反対側の空間を通過する風、つまり風導筒７に臨む空間を通過する風は、光源ユニット４からの受熱量は小さく、光源ユニット４に臨む空間を通過する風よりも温度は低い。風導筒７に臨む空間を通過する風の温度は約３５℃である。したがって、温度センサー９８を比較的温度の低い風により冷却できるので、温度センサー９８が光を受けつつもそれ自体の温度をより低いところでキープすることができる。これによって、作動温度が低い温度センサー９８を使用することができ、何らかの原因で風量が低下した異常状態のとき同センサー９８を異常から早い段階で作動させることができる。仕切壁１３０の一端が光源ユニット４よりも前方に突出しているので、温度センサー９８に風導筒７に臨む空間を通過する比較的温度の低い風を確実に接触させることができる。 Since the partition wall 130 is provided between the light source unit 4 and the air guide tube 7 in this way, the air sent from the blower fan 3 is divided by the partition wall 130. Among the divided winds, the temperature of the wind passing through the space facing the light source unit 4 rises due to heat exchange with the heat generating light source unit 4. The temperature of the wind passing through the space facing the light source unit 4 is about 60 ° C. On the other hand, among the divided winds, the wind passing through the space on the opposite side of the space facing the light emitting structure 4 with the partition wall 130 interposed therebetween, that is, the wind passing through the space facing the wind guide tube 7, is emitted from the light source unit 4. The amount of heat received is small, and the temperature is lower than the wind passing through the space facing the light source unit 4. The temperature of the wind passing through the space facing the air guide tube 7 is about 35 ° C. Therefore, since the temperature sensor 98 can be cooled by the wind having a relatively low temperature, it is possible to keep the temperature of the temperature sensor 98 at a lower temperature while receiving the light. As a result, the temperature sensor 98 having a low operating temperature can be used, and the sensor 98 can be activated at an early stage from an abnormality in an abnormal state in which the air volume is lowered for some reason. Since one end of the partition wall 130 projects forward of the light source unit 4, it is possible to reliably bring the temperature sensor 98 into contact with the air having a relatively low temperature passing through the space facing the air guide tube 7.
　また図３に示すように、仕切壁１３０の一端側に屈曲部１３３を設けることで仕切壁１３０の一端が光源ユニット４の照射開口に近づく向きに傾斜させている。これにより、温度センサー９８に、発光構造４に臨む空間とは仕切壁１３０を挟んで反対側の空間を通過する風、つまり風導筒７に臨む空間を通過する比較的温度の低い風を十分な量接触させることができる。仕切壁１３０の傾斜角度は、温度センサー９８が取り付けられている風導筒７の壁面の傾斜角度よりも急角度に傾斜している。これにより温度センサー９８に発光構造４に臨む空間とは仕切壁１３０を挟んで反対側の空間を通過する風を積極的に接触させることができる。また図２に示すように、仕切壁１３０の他端が光源ユニット４よりも後方、すなわち風の送風方向とは逆方向に突出している。これにより、送風ファン３から送給される風が光源ユニット４よりも後方側（風の流れの上流側）において仕切壁１３０により分断することができるので、光源ユニット４によって加熱されるのをより抑制した低い温度の風を温度センサー９８に接触させることができる。また、仕切壁１３０の他端側に屈曲部１３４を設けることで仕切壁１３０の他端を光源ユニット４の後端に近づく向きに傾斜させている。これにより、送風ファン３から送給される風を積極的に風導筒７に臨む分断空間に送給することができ、温度センサー９８の冷却を促進できる。平面視長方形状の仕切壁１３０の短辺の幅寸法は、温度センサー９８の、上記仕切板１３０の短辺方向の幅寸法よりも大きく設定されている。これにより、光源ユニット４に臨む空間を通過する風と風導筒７に臨む空間を通過する風とが混ざり合い難くなり、温度の低い風を温度センサー９８に接触させることができる。 Further, as shown in FIG. 3, a bent portion 133 is provided on one end side of the partition wall 130 so that one end of the partition wall 130 is inclined toward the irradiation opening of the light source unit 4. As a result, the temperature sensor 98 is sufficiently protected from the wind passing through the space on the opposite side of the space facing the light emitting structure 4 with the partition wall 130 interposed therebetween, that is, the wind passing through the space facing the air guide tube 7 having a relatively low temperature. Can be contacted in any amount. The inclination angle of the partition wall 130 is steeper than the inclination angle of the wall surface of the air guide tube 7 to which the temperature sensor 98 is attached. Thereby, the temperature sensor 98 can positively contact the wind passing through the space on the opposite side of the space facing the light emitting structure 4 with the partition wall 130 interposed therebetween. Further, as shown in FIG. 2, the other end of the partition wall 130 projects behind the light source unit 4, that is, in the direction opposite to the air blowing direction. Accordingly, the air blown from the blower fan 3 can be divided by the partition wall 130 at the rear side (upstream side of the wind flow) of the light source unit 4, so that the light source unit 4 can be more heated. The suppressed low temperature air can be brought into contact with the temperature sensor 98. Further, by providing the bent portion 134 on the other end side of the partition wall 130, the other end of the partition wall 130 is inclined so as to approach the rear end of the light source unit 4. Thereby, the air blown from the blower fan 3 can be positively fed to the divided space facing the air guide tube 7, and the cooling of the temperature sensor 98 can be promoted. The width dimension of the short side of the partition wall 130 having a rectangular shape in plan view is set to be larger than the width dimension of the temperature sensor 98 in the short side direction of the partition plate 130. This makes it difficult for the wind passing through the space facing the light source unit 4 and the wind passing through the space facing the air guide tube 7 to mix with each other, and the low temperature wind can be brought into contact with the temperature sensor 98.
　仕切壁１３０は、光源ユニット４に臨む空間を通過する風に比べて、光源ユニット４に臨む空間とは仕切壁１３０を挟んで反対側の空間を通過する風の温度を低く設定できれば、平板で形成する必要はなく、上向きに開口する断面コ字状で、平面視長方形状の構成であってもよい。この構成であれば風のガイド機能が向上することができ風の温度をより低く設定することができる。さらに、断面口字形状で、平面視長方形状の構成、すなわち閉鎖空間をつくるチューブ構成であってもよい。このときチューブは耐熱性樹脂、金属製など剛性の高い材質で構成できるが、場合によっては柔軟性を有するチューブで構成することができる。この場合、チューブの上流端開口を送風ファン３に正対させ内蔵部品を避けながら引き回してその下流端開口を温度センサー９８に正対させればよい。チューブは断面円形、断面三角形であってもよい。このように閉鎖空間を形成するような形態の仕切壁においても特許請求の範囲の「仕切壁」の範疇である。 The partition wall 130 is a flat plate as long as the temperature of the wind passing through the space opposite to the space facing the light source unit 4 can be set lower than the wind passing through the space facing the light source unit 4. It does not need to be formed, and may have a U-shaped cross-section that opens upward and have a rectangular shape in plan view. With this configuration, the wind guide function can be improved and the wind temperature can be set lower. Further, the configuration may be a V-shaped cross section and a rectangular configuration in plan view, that is, a tube configuration that forms a closed space. At this time, the tube can be made of a highly rigid material such as heat resistant resin or metal, but in some cases, can be made of a flexible tube. In this case, the upstream end opening of the tube may be faced to the blower fan 3 and drawn around while avoiding the built-in parts, and the downstream end opening thereof may be faced to the temperature sensor 98. The tube may have a circular cross section or a triangular cross section. Such a partition wall that forms a closed space is also within the scope of the "partition wall" in the claims.
　温度センサー９８は、サーモスタットに替えて正特性サーミスタ、負特性サーミスタあるいはその他の半導体センサーなどを用いることができる。この場合、同センサーからの信号を先の制御部に送りこの制御部によりハロゲンランプ２８の出力をゼロにするあるいは出力を低下させる制御を行う。場合によって後述する温度ヒューズを上述した位置に設けることもできる。 As the temperature sensor 98, a positive characteristic thermistor, a negative characteristic thermistor, or another semiconductor sensor can be used instead of the thermostat. In this case, a signal from the same sensor is sent to the previous control unit, which controls the output of the halogen lamp 28 to zero or lowers it. In some cases, a thermal fuse, which will be described later, can be provided at the above-mentioned position.
　導風壁４６とハロゲンランプ２８の間は光源冷却通路となっており、これを通過する風によりハロゲンランプ２８や導風壁４６は冷却される。上記冷却通路を流れる風は第１通気口４８に流れ込む。第１通気口４８を通過した風は、ハロゲンランプ２８とリフレクタ２９の間の光源冷却通路を流れて第２通気口４２からリフレクタ２９の外へ流出する。上記冷却通路を流れる風はハロゲンランプ２８やリフレクタ２９を冷却する。 A light source cooling passage is provided between the baffle wall 46 and the halogen lamp 28, and the halogen lamp 28 and the baffle wall 46 are cooled by the wind passing therethrough. The air flowing through the cooling passage flows into the first ventilation port 48. The wind passing through the first ventilation port 48 flows through the light source cooling passage between the halogen lamp 28 and the reflector 29 and flows out of the reflector 29 from the second ventilation port 42. The air flowing through the cooling passage cools the halogen lamp 28 and the reflector 29.
　第１反射面３９と、第２反射面４０と、第３反射面４３はそれぞれ以下のように構成されている。第１反射面３９は、楕円状の曲面で形成されている。また、第２反射面４０はハロゲンランプ２８の発光部３６を中心にした円弧面で形成されている。さらに、第３反射面４３は、楕円状の曲面、または放物線状の曲面で形成されている。このように、第２反射面４０がハロゲンランプ２８の発光部３６を中心にした円弧面で形成されていると、ハロゲンランプ２８から照射されて、第２反射面４０で反射されて第３反射面４３に向かう光の軌跡と、ハロゲンランプ２８から第３反射面４３に向かって直接照射される光の軌跡とを一致させることができる。本実施例においては、第１反射面３９で反射案内されてフィルタ３０へ向かう光と、第３反射面４３で反射案内されてフィルタ３０へ向かう光とは、発光部３６から約３０ｃｍ前方の本体ケース１の外部で集光される。ただし、発光部３６から照射される光の全量が集光されるわけではなく、発光部３６からの光の一部はリフレクタ２９の前面の照射開口から拡散されて照射される。この拡散された光（赤外線）の一部が温度センサー９８に照射されて同センサー９８が温度上昇している。 The first reflecting surface 39, the second reflecting surface 40, and the third reflecting surface 43 are configured as follows. The first reflecting surface 39 is formed of an elliptic curved surface. The second reflecting surface 40 is formed as an arc surface centering on the light emitting portion 36 of the halogen lamp 28. Furthermore, the third reflecting surface 43 is formed of an elliptic curved surface or a parabolic curved surface. As described above, when the second reflecting surface 40 is formed of an arc surface having the light emitting portion 36 of the halogen lamp 28 as the center, the halogen lamp 28 irradiates the second reflecting surface 40 with the second reflecting surface 40 and the third reflecting surface. It is possible to match the trajectory of the light directed to the surface 43 with the trajectory of the light directly emitted from the halogen lamp 28 toward the third reflection surface 43. In this embodiment, the light that is reflected and guided by the first reflecting surface 39 toward the filter 30 and the light that is reflected and guided by the third reflecting surface 43 toward the filter 30 are located approximately 30 cm ahead of the light emitting unit 36. The light is collected outside the case 1. However, not all the light emitted from the light emitting unit 36 is collected, and a part of the light emitted from the light emitting unit 36 is diffused and emitted from the irradiation opening on the front surface of the reflector 29. A part of the diffused light (infrared ray) is applied to the temperature sensor 98, and the temperature of the sensor 98 rises.
　上記のように、３個の反射面３９・４０・４３を備えたリフレクタ２９によれば、ハロゲンランプ２８から照射されて各反射面３９・４０・４３に到達した光を、各反射面３９・４０・４３で効率良く反射案内してフィルタ３０に向って照射させることができる。また、前後に長いハロゲンランプ２８の発光部（フィラメント）３６の軸方向の中心を、第２反射面４０と第３反射面４３の隣接部分に臨ませたので、リフレクタ２９の径方向寸法が大きくなるのを防止してコンパクト化を実現しながら、ハロゲンランプ２８から照射された光をフィルタ３０に向かって照射させることができる。これは、ハロゲンランプ２８から照射された光を、例えば１個の反射面のみで反射案内する場合には、リフレクタ２９の照射開口の直径寸法が大きくなってしまい、その分だけリフレクタ２９が大形になるからである。発光部３６は、その発光中心が第２反射面４０と第３反射面４３の隣接部分に一致する状態で配置させる必要はなく、軸方向に長い発光部３６の一部が、第２反射面４０と第３反射面４３の隣接部分にオーバーラップしていればよい。さらに、第１反射面３９と、第２反射面４０と、第３反射面４３を備えたリフレクタ２９の前後寸法を、リフレクタ２９の径方向寸法より大きく設定したので、前後に長いハロゲンランプ２８を使用するのに適した細長い筒構造のリフレクタ２９を構成することができ、リフレクタ２９の径方向寸法が小さい分だけドライヤーをコンパクト化することができる。 As described above, according to the reflector 29 having the three reflecting surfaces 39, 40, 43, the light emitted from the halogen lamp 28 and reaching each reflecting surface 39, 40, 43 is reflected by each reflecting surface 39. It is possible to efficiently reflect and guide 40 and 43 toward the filter 30 for irradiation. Further, since the axial center of the light emitting portion (filament) 36 of the halogen lamp 28 which is long in the front and rear is made to face the adjacent portion of the second reflecting surface 40 and the third reflecting surface 43, the radial dimension of the reflector 29 is large. The light emitted from the halogen lamp 28 can be emitted toward the filter 30 while preventing this from happening and realizing a compact size. This is because, when the light emitted from the halogen lamp 28 is reflected and guided by, for example, only one reflecting surface, the diameter dimension of the irradiation opening of the reflector 29 becomes large, and the reflector 29 becomes large by that amount. Because. It is not necessary to arrange the light emitting section 36 such that the light emission center thereof coincides with the adjacent portion of the second reflecting surface 40 and the third reflecting surface 43. It suffices that the portion 40 and the third reflection surface 43 are adjacent to each other. Further, since the front-rear dimension of the reflector 29 having the first reflecting surface 39, the second reflecting surface 40, and the third reflecting surface 43 is set to be larger than the radial dimension of the reflector 29, the halogen lamp 28 that is long in the front-rear direction can be used. It is possible to configure the reflector 29 having an elongated tubular structure suitable for use, and the dryer can be made compact due to the small radial dimension of the reflector 29.
　上記の光源支持構造によれば、導風壁４６とハロゲンランプ２８の間の光源冷却通路が第１通気口４８と連通されるので、導風壁４６の後端開口から導入した乾燥風を、第１通気口４８からリフレクタ２９の内部へ流動させ、リフレクタ２９の内部を換気することができる。また、このとき第１通気口４８からリフレクタ２９の内部へ流動させた乾燥風を、ハロゲンランプ２８およびリフレクタ２９に接触させることで、これらハロゲンランプ２８およびリフレクタ２９を効果的に冷却して、ハロゲンランプ２８およびリフレクタ２９の温度上昇を抑制することができる。また、ビス４７を緩めてソケット３４を光源台４５から取外すことにより、ハロゲンランプ２８およびソケット３４をリフレクタ２９から簡単に分離することができ、また、プラグ３３をソケット３４から抜外すことにより、ハロゲンランプ２８をソケット３４から分離できるので、ハロゲンランプ２８が故障した場合の交換作業を容易に行うことができる。 According to the above light source support structure, the light source cooling passage between the air guide wall 46 and the halogen lamp 28 communicates with the first ventilation port 48, so that the dry air introduced from the rear end opening of the air guide wall 46 is The inside of the reflector 29 can be ventilated by causing the first vent 48 to flow into the inside of the reflector 29. Further, at this time, the dry air that has flowed from the first ventilation port 48 into the reflector 29 is brought into contact with the halogen lamp 28 and the reflector 29, so that the halogen lamp 28 and the reflector 29 are effectively cooled, and the halogen lamp 28 and the reflector 29 are cooled. The temperature rise of the lamp 28 and the reflector 29 can be suppressed. Further, the halogen lamp 28 and the socket 34 can be easily separated from the reflector 29 by loosening the screw 47 and removing the socket 34 from the light source base 45, and by removing the plug 33 from the socket 34, the halogen lamp 28 and the socket 34 can be easily separated. Since the lamp 28 can be separated from the socket 34, replacement work can be easily performed when the halogen lamp 28 fails.
　前リフレクタ３７と後リフレクタ３８は、第２反射面４０と第３反射面４３とが隣接する状態で接合されて締結固定されている。両リフレクタ３７・３８を締結固定するために、分割体３７ａ・３７ｂの後縁に位置する係合壁５７に前係合部（凸状係合部）５１が折曲げられた状態で径方向へ突出形成されている。また、後リフレクタ３８の前端に、前リフレクタ３７の係合壁５７を嵌合支持する接合溝５２と、前リフレクタ３７の係合壁５７の周面を支持する接合壁５３が形成されており、さらに接合壁５３の対向２個所には、接合壁５３を切欠いて形成される後係合部（凹状係合部）５４とねじボス５５とが形成されている。 The front reflector 37 and the rear reflector 38 are joined and fastened to each other with the second reflecting surface 40 and the third reflecting surface 43 adjacent to each other. In order to fasten and fix both reflectors 37, 38, the front engagement portion (convex engagement portion) 51 is bent in the radial direction in the engagement wall 57 located at the rear edge of the divided bodies 37a, 37b. It is formed to project. Further, at the front end of the rear reflector 38, a joint groove 52 for fitting and supporting the engagement wall 57 of the front reflector 37 and a joint wall 53 for supporting the peripheral surface of the engagement wall 57 of the front reflector 37 are formed. Further, a rear engagement portion (concave engagement portion) 54 formed by cutting out the joint wall 53 and a screw boss 55 are formed at two opposing portions of the joint wall 53.
　一対の分割体３７ａ・３７ｂを接合し、前係合部５１と後係合部５４とを凹凸係合させることにより、前リフレクタ３７と後リフレクタ３８とを接合することができる。また、前係合部５１の貫通孔５１ａに挿通したビス５６をねじボス５５にねじ込むことにより、前リフレクタ３７と後リフレクタ３８とを一体化できる。上記のように、前リフレクタ３７と後リフレクタ３８とは、前リフレクタ３７の係合壁５７と接合溝５２の係合により、径方向のずれ動きが阻止されており、さらに、前係合部５１と後係合部５４の係合により、中心軸Ｐ回りの回動が阻止されている。さらに、前係合部５１に挿通したビス５６をねじボス５５にねじ込むだけで、前リフレクタ３７と後リフレクタ３８を一体化できるので、前後のリフレクタ３７・３８をより簡単な締結構造で強固に固定することができる。従って、リフレクタ２９に設けた反射面３９・４０・４３の光学特性を常に一定にすることができる。なお、前係合部５１、後係合部５４、ビス５６は、対向２個所にある必要はなく、１個所のみで構成することができる。前リフレクタ３７は、３以上の分割体を接合して構成してもよい。 The front reflector 37 and the rear reflector 38 can be joined by joining the pair of divided bodies 37a and 37b and engaging the front engaging portion 51 and the rear engaging portion 54 with each other. Further, the front reflector 37 and the rear reflector 38 can be integrated by screwing the screw 56 inserted into the through hole 51a of the front engaging portion 51 into the screw boss 55. As described above, the front reflector 37 and the rear reflector 38 are prevented from being displaced in the radial direction by the engagement between the engagement wall 57 of the front reflector 37 and the joint groove 52, and further, the front engagement portion 51. By the engagement of the rear engaging portion 54, the rotation around the central axis P is prevented. Further, the front reflector 37 and the rear reflector 38 can be integrated by simply screwing the screw 56 inserted through the front engaging portion 51 into the screw boss 55, so that the front and rear reflectors 37 and 38 are firmly fixed by a simpler fastening structure. can do. Therefore, the optical characteristics of the reflecting surfaces 39, 40, 43 provided on the reflector 29 can be made constant at all times. The front engagement portion 51, the rear engagement portion 54, and the screw 56 do not need to be provided at two opposing positions, and can be configured at only one location. The front reflector 37 may be configured by joining three or more divided bodies.
　前リフレクタ３７（リフレクタ２９）の左側面には温度ヒューズ３７ｃを固定するヒューズホルダー３７ｄが前リフレクタ３７と一体で設けられている。ヒューズホルダー３７ｄの先端には温度ヒューズ３７ｄを支持する凹部３７ｅが設けられる。この凹部３７ｅに温度ヒューズ３７ｄを支持した状態で固定プレート３７ｆをヒューズホルダー３７ｄにビスなどで締結手段で固定することでヒューズホルダー３７ｄに温度ヒューズ３７ｃを固定できる。温度ヒューズ３７ｃが切断される設定温度は１６９℃となっており、先の温度センサー９８の作動温度よりも高く設定されている。温度ヒューズ３７ｃはドライヤー全体に電力を供給するラインに接続されているので、温度ヒューズ３７ｃが切断されれば、ドライヤーのすべての装置が停止する。これにより先の温度センサー９８が何らかの原因により作動せずにケース構造１内がさらに温度上昇した場合は温度ヒューズ３７ｃの切断によって安全性が確保できている。通常の使用状態の場合、温度ヒューズ３７ｃは１１０℃を保った状態となっている。使用状態からメインスイッチ１３をオフにした不使用状態にすると前リフレクタ３７の余熱により温度ヒューズ３７ｃが熱伝導により加熱されて１５０℃まで上昇するが温度ヒューズ３７ｃが切断される温度までには上昇しない。 A fuse holder 37d for fixing the temperature fuse 37c is provided integrally with the front reflector 37 on the left side surface of the front reflector 37 (reflector 29). A concave portion 37e that supports the thermal fuse 37d is provided at the tip of the fuse holder 37d. The temperature fuse 37c can be fixed to the fuse holder 37d by fixing the fixing plate 37f to the fuse holder 37d with a fastening means such as a screw while the temperature fuse 37d is supported in the recess 37e. The set temperature at which the thermal fuse 37c is cut is 169 ° C., which is set higher than the operating temperature of the temperature sensor 98. Since the thermal fuse 37c is connected to a line that supplies electric power to the entire dryer, if the thermal fuse 37c is cut off, all the devices of the dryer are stopped. As a result, if the temperature sensor 98 does not operate for some reason and the temperature inside the case structure 1 further rises, safety can be secured by cutting the temperature fuse 37c. In the normal use state, the temperature fuse 37c is maintained at 110 ° C. When the main switch 13 is turned off from the use state to the non-use state, the temperature fuse 37c is heated by heat conduction due to the residual heat of the front reflector 37 and rises to 150 ° C., but does not rise to the temperature at which the temperature fuse 37c is cut. ..
　フィルタ３０は低膨張性ガラスで形成されており、フィルタ支持構造５９で前リフレクタ３７の照射開口に固定されている。フィルタ支持構造５９は、前リフレクタ３７に形成したフィルタ受座４１と、フィルタ受座４１と協同してフィルタ３０を前後に挟持固定する押えリング６０とからなる。押えリング６０は、フィルタ３０の前周縁を押え保持する端壁６１と、フィルタ受座４１の外周面に外嵌するリング状の周回壁６２とを備えており、この周回壁６２が後述する防眩壁７５として機能する。図４に示すように、押えリング６０はビス６３で前リフレクタ３７に固定されている。フィルタ受座４１はフィルタ３０の周面および後周縁に密着されており、フィルタ３０の熱を前リフレクタ３７側へ効果的に伝導させて、フィルタ３０の冷却を促進し常に適温状態に維持することができる。 The filter 30 is made of low-expansion glass, and is fixed to the irradiation opening of the front reflector 37 by the filter support structure 59. The filter support structure 59 includes a filter seat 41 formed on the front reflector 37, and a holding ring 60 that cooperates with the filter seat 41 to sandwich and fix the filter 30 back and forth. The pressing ring 60 includes an end wall 61 that presses and holds the front peripheral edge of the filter 30 and a ring-shaped surrounding wall 62 that is externally fitted to the outer peripheral surface of the filter seat 41. It functions as the glare wall 75. As shown in FIG. 4, the pressing ring 60 is fixed to the front reflector 37 with screws 63. The filter seat 41 is closely attached to the peripheral surface and the rear peripheral edge of the filter 30, and effectively conducts the heat of the filter 30 to the front reflector 37 side to promote the cooling of the filter 30 and always maintain an appropriate temperature. You can
　上記のように、フィルタ支持構造５９は、前リフレクタ３７に形成したフィルタ受座４１と、同受座４１と協同してフィルタ３０を挟持固定する押えリング６０を備える。こうしたフィルタ支持構造５９によれば、フィルタ３０をフィルタ受座４１に組み、押えリング６０を前リフレクタ３７の前部周面に外嵌し固定することで、フィルタ３０を前リフレクタ３７に簡単に組んで、分離不能にしっかりと固定することができる。 As described above, the filter support structure 59 includes the filter seat 41 formed on the front reflector 37 and the holding ring 60 that clamps and fixes the filter 30 in cooperation with the seat 41. According to such a filter support structure 59, the filter 30 is assembled to the filter seat 41, and the pressing ring 60 is externally fitted and fixed to the front peripheral surface of the front reflector 37, whereby the filter 30 is easily assembled to the front reflector 37. Therefore, it can be firmly fixed inseparably.
　ハロゲンランプ２８は衝撃に弱く、大きな外力が作用するとフィラメントが揺れ動いて
ショートし断線するおそれがある。ハロゲンランプ２８に外部衝撃が作用するのを防ぐために、光源ユニット４は本体ケース１に対して浮動支持されている。詳しくは図４に示すように、光源ユニット４は、光源ユニット４の前部と風導筒７の間に設けた前支持構造と、光源ユニット４の後部と風導筒７の間に設けた後支持構造とで支持されている。 The halogen lamp 28 is vulnerable to impact, and when a large external force is applied, the filament may oscillate, causing a short circuit and disconnection. The light source unit 4 is supported in a floating manner with respect to the main body case 1 in order to prevent an external impact from acting on the halogen lamp 28. More specifically, as shown in FIG. 4, the light source unit 4 is provided between the front portion of the light source unit 4 and the air guide tube 7, and between the rear portion of the light source unit 4 and the air guide tube 7. It is supported by the rear support structure.
　図１および図１０に示すように後支持構造は、光源支持構造の周囲を囲む風導筒７の内面に、光源ユニット４を支持するリング状のばね受枠６４を固定し、後リフレクタ３８とばね受枠６４の対向面の３個所に、光源ユニット４を支持する圧縮コイルばね（ばね体）からなる衝撃吸収ばね６９を配置している。前支持構造は、図１および図１１に示すように、フィルタ３０の周囲を囲む風導筒７の内面に、光源ユニット４を支持する６角リング状のユニット支持枠６６を固定し、後述する防眩壁７５とユニット支持枠６６の対向面の３個所に、光源ユニット４を支持するゲル状の粘弾性体６７を配置している。このように本実施例１では、前支持構造の衝撃吸収構造６５は、粘弾性体６７を衝撃吸収要素にして構成されており、後支持構造の衝撃吸収構造６５は、金属製の衝撃吸収ばね６９を衝撃吸収要素にして構成されている。粘弾性体６７は、低反発性の高分子ゲル、ゴム、熱可塑性エラストマーなどで形成することができる。 As shown in FIGS. 1 and 10, in the rear support structure, a ring-shaped spring receiving frame 64 that supports the light source unit 4 is fixed to the inner surface of the air guide tube 7 that surrounds the periphery of the light source support structure, and the rear reflector 38 and the spring. Impact absorbing springs 69, which are compression coil springs (spring bodies) that support the light source unit 4, are arranged at three positions on the opposing surface of the receiving frame 64. In the front support structure, as shown in FIGS. 1 and 11, a hexagonal ring-shaped unit support frame 66 that supports the light source unit 4 is fixed to the inner surface of the air guide tube 7 that surrounds the periphery of the filter 30, which will be described later. Gel-like viscoelastic bodies 67 that support the light source unit 4 are arranged at three locations on the opposing surfaces of the antiglare wall 75 and the unit support frame 66. As described above, in the first embodiment, the shock absorbing structure 65 of the front supporting structure is configured by using the viscoelastic body 67 as a shock absorbing element, and the shock absorbing structure 65 of the rear supporting structure is the shock absorbing spring made of metal. 69 is used as a shock absorbing element. The viscoelastic body 67 can be formed of low-resilience polymer gel, rubber, thermoplastic elastomer, or the like.
　後支持構造のばね受枠６４は、金属製の板ばねで形成した３個のばね腕７０を６角枠状に連結して構成されており、各ばね腕７０の中央には、衝撃吸収ばね６９の一端を受止めるばね座７１が形成されている。ばね座７１と対向する後リフレクタ３８の導風壁４６にも衝撃吸収ばね６９の他端を受止めるばね座７２が形成されている。衝撃吸収ばね６９は金属線材で形成した円錐コイルばね（ばね体）からなり、その大径部がばね座７２で支持され、小径部がばね座７１で支持されている。前支持構造のユニット支持枠６６は、板ばねで６角枠状に形成されており、その３個所に粘弾性体６７を保持するゲル保持部７３が形成されている。ゲル保持部７３は側面視において断面角樋状に形成されており、粘弾性体６７は、角樋断面を備えるゲル保持部７３の前後端にわたってその内面側に固定されている。これらユニット支持枠６６および粘弾性体６７は、各粘弾性体６７の内面が押えリング６０の外周面に密着する状態でリフレクタ２９に装着されており、このとき粘弾性体６７の前後端は、押えリング６０の前後縁に被さっている（図１参照）。これにより、押えリング６０（リフレクタ２９）と粘弾性体６７とは、リフレクタ２９の径方向に凹凸係している。ばね受枠６４およびユニット支持枠６６は板バネ材で形成してあるので、本体ケース１に外部衝撃が作用する場合には、それぞれ厚み方向へ弾性変形して衝撃を吸収することができる。従って、ばね受枠６４と衝撃吸収ばね６９、およびユニット支持枠６６と粘弾性体６７が、それぞれ協働して外部衝撃を効果的に緩和し吸収できる。なお、ばね受枠６４とユニット支持枠６６は剛体であってもよいが、その場合には、衝撃吸収ばね６９および粘弾性体６７のみで外部衝撃を緩和吸収するとよい。 The spring support frame 64 of the rear support structure is configured by connecting three spring arms 70 formed of metal leaf springs in a hexagonal frame shape. At the center of each spring arm 70, a shock absorbing spring 69 is formed. A spring seat 71 is formed to receive one end of the spring seat 71. A spring seat 72 that receives the other end of the shock absorbing spring 69 is also formed on the wind guide wall 46 of the rear reflector 38 that faces the spring seat 71. The shock absorbing spring 69 is composed of a conical coil spring (spring body) formed of a metal wire, a large diameter portion of which is supported by a spring seat 72 and a small diameter portion of which is supported by a spring seat 71. The unit support frame 66 of the front support structure is formed of a leaf spring into a hexagonal frame shape, and gel holding portions 73 for holding the viscoelastic body 67 are formed at three positions thereof. The gel holding portion 73 is formed in a gutter-shaped cross section in a side view, and the viscoelastic body 67 is fixed to the inner surface side of the gel holding portion 73 having a gutter cross section over the front and rear ends thereof. The unit support frame 66 and the viscoelastic body 67 are attached to the reflector 29 with the inner surface of each viscoelastic body 67 in close contact with the outer peripheral surface of the pressing ring 60. At this time, the front and rear ends of the viscoelastic body 67 are It covers the front and rear edges of the presser ring 60 (see FIG. 1). As a result, the pressing ring 60 (reflector 29) and the viscoelastic body 67 are engaged with each other in the radial direction of the reflector 29. Since the spring receiving frame 64 and the unit supporting frame 66 are formed of a leaf spring material, when an external impact is applied to the main body case 1, they can be elastically deformed in the thickness direction to absorb the impact. Therefore, the spring receiving frame 64 and the shock absorbing spring 69, and the unit supporting frame 66 and the viscoelastic body 67 cooperate with each other to effectively absorb and absorb the external shock. The spring receiving frame 64 and the unit supporting frame 66 may be rigid bodies, but in that case, it is preferable that only the shock absorbing spring 69 and the viscoelastic body 67 absorb and absorb the external shock.
　使用時には、ハロゲンランプ２８を点灯し、送風ファン３を駆動して、フィルタ３０を通過した赤外線を髪に照射し、さらに、送風ファン３から送給された乾燥風（冷却風）を髪に送給して髪の乾燥を行う。乾燥風の一部は後開口５８から導風壁４６内へ導入され、光源冷却通路から第１通気口４８へ流入しながら、ハロゲンランプ２８とリフレクタ２９、およびフィルタ３０を冷却したのち、第２通気口４２からリフレクタ２９の外へ流出し、導風路９を流動する乾燥風と合流して吹出口１１から送出される。送風ファン３から送給された乾燥風の一部は、光源ユニット４の周囲の導風路９に沿って流動する間に、第２通気口４２の周囲を負圧状態にする。従って、ベンチュリー効果によって、リフレクタ２９内部の第２通気口４２の付近の空気が先の乾燥風に引寄せられて合流し、吹出口１１へと送出される。 At the time of use, the halogen lamp 28 is turned on, the blower fan 3 is driven to irradiate the hair with the infrared rays that have passed through the filter 30, and the dry air (cooling air) sent from the blower fan 3 is sent to the hair. To dry the hair. A part of the dry air is introduced into the air guide wall 46 through the rear opening 58, cools the halogen lamp 28, the reflector 29, and the filter 30 while flowing into the first ventilation port 48 from the light source cooling passage, and then the second air. The air flows out of the reflector 29 from the ventilation port 42, merges with the dry air flowing in the air guide passage 9, and is discharged from the air outlet 11. A part of the dry air sent from the blower fan 3 puts a negative pressure around the second ventilation port 42 while flowing along the air guide passage 9 around the light source unit 4. Therefore, due to the Venturi effect, the air in the vicinity of the second ventilation port 42 inside the reflector 29 is attracted by the dry air and merges, and is delivered to the air outlet 11.
　乾燥風が第２通気口４２から流出するとき、ハロゲンランプ２８から照射された光の一部が第２通気口４２から漏れ出てしまう。このように、第２通気口４２から漏れ出た光が吹出口１１から照射されて、髪乾燥時のユーザーに眩しさを感じさせるのを防ぐために、第２通気口４２の外面に、第２通気口４２から漏れ出た光を吹出口１１から遠ざかる向きに変向案内する防眩構造が設けられている。図９において防眩構造は、第２通気口４２の開口外面を覆う筒状の防眩壁７５を備えており、先に説明した周回壁６２が防眩壁７５を兼ねている。 When the dry air flows out from the second ventilation port 42, part of the light emitted from the halogen lamp 28 leaks out from the second ventilation port 42.

Can be sent from
　マイナスイオンを乾燥風とともに髪へ送給するために、吹出口１１に臨む風導筒７の内部にイオン放出構造を設けるとともに、風導筒７を光源ユニット４と吹出口１１の間で前すぼまり状に形成している。図３および図４においてイオン放出構造は、絶縁材で形成される横長長円状の電極ホルダー９１と、電極ホルダー９１で支持される３個の放電電極９２と、放電電極９２の周囲を囲む横長長円状の筒壁９３と、筒壁９３の周囲に固定される対向電極９４とを備えている。さらに電極ホルダー９１には、対向電極９４の外側周囲に横長長円状の外筒壁９３ａが設けられており、これら筒壁９３と外筒壁９３ａとで電極ホルダー９１の前半部は２重筒状に構成されている。このように外筒壁９３ａを設けることにより、放電電極９２から放出されたマイナスイオンが、対向電極９４の外面側へとまわり込むのを阻止して、当該マイナスイオンが対向電極９４に吸収されるのを抑制できる。図５に示すように対向電極９４の前縁には一群の尖端放電部９４ａが形成されている。電極ホルダー９１は風導筒７に設けた一対の挟持壁９５で挟持固定されて、放電電極９２がイオン通口９７に指向されている。 In order to send the negative ions to the hair along with the dry air, an ion emission structure is provided inside the air guide tube 7 facing the air outlet 11, and the air guide tube 7 is placed between the light source unit 4 and the air outlet 11. It is formed like a lump. In FIG. 3 and FIG. 4, the ion emission structure has an oblong electrode holder 91 formed of an insulating material, three discharge electrodes 92 supported by the electrode holder 91, and an oblong electrode surrounding the discharge electrode 92. It is provided with an elliptic cylindrical wall 93 and a counter electrode 94 fixed around the cylindrical wall 93. Further, the electrode holder 91 is provided with a laterally elongated oval outer cylinder wall 93a around the outer side of the counter electrode 94. The front half of the electrode holder 91 is a double cylinder due to the cylinder wall 93 and the outer cylinder wall 93a. It is configured in a shape. By providing the outer cylinder wall 93a in this manner, the negative ions emitted from the discharge electrode 92 are prevented from entering the outer surface side of the counter electrode 94, and the negative ions are absorbed by the counter electrode 94. Can be suppressed. As shown in FIG. 5, a group of tip discharge parts 94a is formed at the front edge of the counter electrode 94. The electrode holder 91 is sandwiched and fixed by a pair of sandwiching walls 95 provided in the air guide tube 7, and the discharge electrode 92 is directed to the ion passage 97.
　上記のように、吹出口１１に臨む風導筒７の内部にイオン放出構造が設けられていると、光源ユニット４から照射される赤外光と、イオン放出構造から放出されるマイナスイオンを乾燥風とともに髪へ送給することができる。従って、髪の乾燥を行いながら、マイナスイオンと結合した空気中の水分を髪に付着させて、髪が不必要に乾燥することを防ぐことができる。また、吹出口１１と正対する側から見るときのイオン放出構造の放電電極９２は光源ユニット４と風導筒７の間に位置されているので、イオン放出構造で生成されたマイナスイオンを導風路９に放出して、送風ファン３から送給される乾燥風とともに吹出口１１から遠くまで送給することができる。 As described above, when the ion emission structure is provided inside the air guide tube 7 facing the air outlet 11, the infrared light emitted from the light source unit 4 and the negative ions emitted from the ion emission structure are dried. Can be delivered to the hair with the wind. Therefore, while drying the hair, it is possible to prevent the moisture in the air combined with the negative ions from adhering to the hair to prevent the hair from being dried unnecessarily. Further, since the discharge electrode 92 of the ion emission structure when viewed from the side directly facing the outlet 11 is located between the light source unit 4 and the air guide tube 7, the negative ions generated by the ion emission structure are introduced. The air can be discharged to the passage 9 and can be sent to a distance from the outlet 11 together with the dry air sent from the blower fan 3.
　以上より、実施例１のドライヤーにおいては、光源ユニット４と本体ケース１との間に衝撃吸収ばね６９と粘弾性体６７とからなる衝撃吸収構造６５を設けたので、本体ケース１に作用する外部衝撃が光源ユニット４に伝わることを、これら衝撃吸収ばね６９と粘弾性体６７とで緩和吸収して、光源ユニット４に外部衝撃が作用することを確実に防止することができる。従って、ドライヤーに落下衝撃や衝突衝撃などの外部衝撃が作用するような場合でも、ハロゲンランプ２８がショートし断線することを確実に防止して耐久性に優れたドライヤーを得ることができる。 As described above, in the dryer of the first embodiment, since the shock absorbing structure 65 including the shock absorbing spring 69 and the viscoelastic body 67 is provided between the light source unit 4 and the main body case 1, the external parts acting on the main body case 1 are provided. It is possible to reliably prevent the impact transmitted to the light source unit 4 from being absorbed by the impact absorbing spring 69 and the viscoelastic body 67, and to apply an external impact to the light source unit 4. Therefore, even when an external impact such as a drop impact or a collision impact acts on the dryer, it is possible to reliably prevent the halogen lamp 28 from short-circuiting and disconnection, and to obtain a dryer having excellent durability.
　本体ケース１の導風路９の内部に光源ユニット４と送風ファン３を配置し、光源ユニット４と本体ケース１の間に設けた衝撃吸収構造６５を、金属製のばね体である衝撃吸収ばね６９を衝撃吸収要素にして構成したので、送風ファン３から送給される乾燥風が、ハロゲンランプ２８からの熱伝導で加熱された衝撃吸収ばね６９と接触することによっても、当該乾燥風を温風化して吹出口１１から送出させることができる。従って、ハロゲンランプ２８から照射される光による加熱作用に加えて、温風化された乾燥風による加熱作用を発揮され、加熱効率に優れたドライヤーを得ることができる。 The light source unit 4 and the blower fan 3 are arranged inside the air guide passage 9 of the main body case 1, and the shock absorbing structure 65 provided between the light source unit 4 and the main body case 1 is a shock absorbing spring which is a metal spring body. Since 69 is configured as a shock absorbing element, the dry air sent from the blower fan 3 also heats the dry air by contacting the shock absorbing spring 69 heated by heat conduction from the halogen lamp 28. It can be weathered and delivered from the outlet 11. Therefore, in addition to the heating effect of the light emitted from the halogen lamp 28, the heating effect of the heated dry air is exerted, and a dryer having excellent heating efficiency can be obtained.
　前支持構造の衝撃吸収構造６５を粘弾性体６７で構成し、後支持構造の衝撃吸収構造６５を衝撃吸収ばね６９で構成したので、光源ユニット４の前部と本体ケース１の位置関係を粘弾性体６７で維持しながら、光源ユニット４の後部の揺れ動きを衝撃吸収ばね６９で緩和吸収することができる。また、上記構成を採ることで、外部衝撃が作用したときにも、前支持構造で支持された光源ユニット４の前部の径方向変位量を、後支持構造で支持された光源ユニット４の後部の径方向変位量より小さくすることができる。以上より、外部衝撃が光源ユニット４のハロゲンランプ２８に伝わることを衝撃吸収ばね６９で緩和吸収しながら、ハロゲンランプ２８から照射される光の照射中心軸が大きくぶれることを防ぐことができるので、吹出口１１の周辺の構造体がハロゲンランプ２８から照射される光を受けて無駄に加熱されることを確実に防止できる。 Since the shock absorbing structure 65 of the front supporting structure is composed of the viscoelastic body 67 and the shock absorbing structure 65 of the rear supporting structure is composed of the shock absorbing spring 69, the positional relationship between the front part of the light source unit 4 and the main body case 1 is viscous. While being held by the elastic body 67, the swaying movement of the rear portion of the light source unit 4 can be alleviated and absorbed by the impact absorbing spring 69. Further, by adopting the above configuration, even when an external impact is applied, the radial displacement amount of the front portion of the light source unit 4 supported by the front support structure can be adjusted to the rear portion of the light source unit 4 supported by the rear support structure. Can be made smaller than the radial displacement amount of. As described above, since the impact absorption spring 69 moderates and absorbs the external impact transmitted to the halogen lamp 28 of the light source unit 4, it is possible to prevent the irradiation center axis of the light emitted from the halogen lamp 28 from largely deviating. It is possible to reliably prevent the structure around the outlet 11 from being unnecessarily heated by receiving the light emitted from the halogen lamp 28.
　また、前支持構造の衝撃吸収構造６５を粘弾性体６７で構成し、後支持構造の衝撃吸収構造６５を衝撃吸収ばね６９で構成したので、本体ケース１に作用する外部衝撃を、光源ユニット４の前部と後部を支持する衝撃吸収構造によって、協同して緩和吸収することができる。従って、光源ユニット４の前部、または後部のみが衝撃吸収構造６５で支持されている構成に比べて、外部衝撃をより効果的に緩和し吸収して、光ハロゲンランプ２８がショートし断線するのをさらに確実に防止できる。リフレクタ２９の前部の径方向寸法を基準にして本体ケース１を構成することができるので、本体ケース１が肥大化するのを避けながら、外部衝撃を粘弾性体６７と衝撃吸収ばね６９とでさらに効果的に緩和吸収することができる。 Further, since the shock absorbing structure 65 of the front supporting structure is composed of the viscoelastic body 67 and the shock absorbing structure 65 of the rear supporting structure is composed of the shock absorbing spring 69, the external shock acting on the main body case 1 is prevented. By the shock absorbing structure supporting the front and rear portions of the, it is possible to cooperatively absorb and absorb. Therefore, as compared with the structure in which only the front part or the rear part of the light source unit 4 is supported by the shock absorbing structure 65, the external shock is more effectively absorbed and absorbed, and the light halogen lamp 28 is short-circuited and disconnected. Can be prevented more reliably. Since the main body case 1 can be configured with the radial dimension of the front portion of the reflector 29 as a reference, the viscoelastic body 67 and the shock absorbing spring 69 prevent external impact from occurring while avoiding enlargement of the main body case 1. Further, it can be absorbed and absorbed more effectively.
　リフレクタ２９と粘弾性体６７とを、リフレクタ２９の径方向に凹凸係合する状態で接合したので、光源ユニット４の径方向移動と前後（中心軸Ｐ）方向の移動を粘弾性体６７で緩和吸収して、光源ユニット４のハロゲンランプ２８が外部衝撃を受けて揺れ動くことを速やかに収斂させることができる。 Since the reflector 29 and the viscoelastic body 67 are joined in a state in which the reflector 29 is engaged in a concavo-convex manner in the radial direction of the reflector 29, the viscoelastic body 67 alleviates the radial movement of the light source unit 4 and the longitudinal (central axis P) movement. It is possible to quickly converge that the halogen lamp 28 of the light source unit 4 absorbs and swings due to an external impact.
　後支持構造の衝撃吸収構造６５を、光源ユニット４の周囲３個所を支持するコイルばねからなる衝撃吸収ばね６９で構成するようにしたので、光源ユニット４のリフレクタ２９を、本体ケース１の中央付近の所定位置に位置保持した状態で浮動支持することができる。また、衝撃吸収ばね６９が外部衝撃を受けて伸縮変形する場合に、各衝撃吸収ばね６９を速やかに収斂させて、光源ユニット４を安定した状態で支持できる。因みに、光源ユニット４の周囲２個所が一対のコイルばねで支持した場合には、光源ユニット４がばね中心線と交差する向きに揺れ動くため、光源ユニット４を安定させるのに余分な時間が掛かる。乾燥風の流れが衝撃吸収ばね６９で乱されるのを極力避けて、乾燥風の送風効率を向上できる利点もある。 Since the shock absorbing structure 65 of the rear support structure is configured by the shock absorbing spring 69 composed of a coil spring that supports three places around the light source unit 4, the reflector 29 of the light source unit 4 is provided near the center of the main body case 1. Can be floatingly supported while being held at a predetermined position. Further, when the shock absorbing springs 69 receive an external shock and expand and contract, the shock absorbing springs 69 can quickly converge to support the light source unit 4 in a stable state. Incidentally, when the two light source units 4 are supported by a pair of coil springs, the light source unit 4 swings in a direction intersecting the spring center line, and therefore it takes extra time to stabilize the light source unit 4. There is also an advantage that the blowing efficiency of the dry air can be improved by avoiding the disturbance of the flow of the dry air by the shock absorbing spring 69 as much as possible.
　本体ケース１の内面にリング状のばね受枠６４を固定し、リフレクタ２９と対向するばね受枠６４の３個所にばね座７１を形成して、ばね座７１とリフレクタ２９の間に、衝撃吸収ばね６９を配置した。これによれば、本体ケース１の内面に固定したばね受枠６４に光源ユニット４のリフレクタ２９を仮組した状態で、３個の衝撃吸収ばね６９を、ばね受枠６４のばね座７１とリフレクタ２９の間に順に組付ければよく、後支持構造をより少ない手間で的確に組むことができる。 A ring-shaped spring receiving frame 64 is fixed to the inner surface of the main body case 1, and spring seats 71 are formed at three positions of the spring receiving frame 64 facing the reflector 29, and a shock absorbing spring 69 is formed between the spring seat 71 and the reflector 29. Was placed. According to this, in the state where the reflector 29 of the light source unit 4 is temporarily assembled to the spring receiving frame 64 fixed to the inner surface of the main body case 1, the three shock absorbing springs 69 are connected to the spring seat 71 of the spring receiving frame 64 and the reflector 29. It suffices to assemble them in order between them, and the rear support structure can be assembled accurately with less effort.
　六角リング状に形成したばね受枠６４の３個のリング枠部に、ばね座７１を周方向へ均等に隣接する状態で配置した。これによれば、直線状のリング枠部にばね座７１を形成すればよく、例えばばね受枠６４が円形リング状に形成してある場合に比べて、ばね座７１を容易に形成できるうえ、衝撃吸収ばね６９をばね座７１で安定した状態で支持することができる。また、ばね受枠６４と本体ケース１の内面の間に空間が形成されるので、ばね受枠６４の内外両面から放熱でき、さらに衝撃吸収ばね６９からも放熱することができ、放熱効果の向上が期待できる。とくに、本実施例のように、本体ケース１の内部に送風ファン３が設けられたドライヤーの場合には、ばね受枠６４と乾燥風の接触面積が大きい分だけ熱交換を促進して、乾燥風を効果的に温風化することができる。 The spring seats 71 are arranged evenly in the circumferential direction on the three ring frame portions of the spring receiving frame 64 formed in a hexagonal ring shape. According to this, the spring seat 71 may be formed on the linear ring frame portion, and the spring seat 71 can be easily formed and the impact can be improved as compared with the case where the spring receiving frame 64 is formed in the circular ring shape, for example. The absorption spring 69 can be stably supported by the spring seat 71. In addition, since a space is formed between the spring receiving frame 64 and the inner surface of the main body case 1, heat can be radiated from both the inner and outer surfaces of the spring receiving frame 64, and further from the shock absorbing spring 69, which is expected to improve the heat radiation effect. it can. Particularly, in the case of a dryer in which the blower fan 3 is provided inside the main body case 1 as in the present embodiment, heat exchange is promoted by the amount of contact area between the spring receiving frame 64 and the dry air, and the dry air is increased. Can be effectively warmed.

　接合溝５２を備えた一方のリフレクタ３８に凹状の後係合部５４を形成し、他方のリフレクタ３７に、後係合部５４と係合する凸状の前係合部５１を形成した。これによれば、凸状係合部５１と凹状係合部５４の係合により、一方のリフレクタ３８に対する他方のリフレクタ３７の中心軸Ｐ回りの回動が阻止された状態で両リフレクタ３７・３８を適正に接合することができる。 A concave rear engaging portion 54 is formed on one reflector 38 having the joining groove 52, and a convex front engaging portion 51 that engages with the rear engaging portion 54 is formed on the other reflector 37. According to this, both the reflectors 37, 38 are prevented in a state in which the rotation of the other reflector 37 with respect to the one reflector 38 around the central axis P is prevented by the engagement of the convex engagement portion 51 and the concave engagement portion 54. Can be properly joined.
　前係合部５１に挿通したビス５６を後係合部５４に形成したねじボス５５にねじ込むことで、前リフレクタ３７と後リフレクタ３８とを分離不能に固定したので、より簡単な締結構造でありながら、前リフレクタ３７と後リフレクタ３８とをビス５６で強固に締結固定することができる。従って、リフレクタ２９に設けた反射面３９・４０・４３の光学特性を常に一定にすることができる。 The front reflector 37 and the rear reflector 38 are inseparably fixed by screwing the screw 56 inserted into the front engaging portion 51 into the screw boss 55 formed in the rear engaging portion 54, which is a simpler fastening structure. However, the front reflector 37 and the rear reflector 38 can be firmly fastened and fixed with the screw 56. Therefore, the optical characteristics of the reflecting surfaces 39, 40, 43 provided on the reflector 29 can be made constant at all times.
　前リフレクタ３７を、複数の分割体３７ａ・３７ｂを接合して構成し、後リフレクタ３８の前リフレクタ３７との接合面に、接合溝５２と接合壁５３とを形成し、また、複数の分割体３７ａ・３７ｂを接合し、前リフレクタ３７の開口周縁壁を接合溝５２および接合壁５３で係合支持し、さらに、前係合部５１と後係合部５４を凹凸係合させて、前リフレクタ３７と後リフレクタ３８を一体化するようにした。こうしたリフレクタ２９によれば、分割体３７ａ・３７ｂを接合し、前係合部５１と後係合部５４を凹凸係合させた状態で、ビス５６をねじボス５５にねじ込むことにより、前リフレクタ３７と後リフレクタ３８とを強固に締結固定することができる。また、前リフレクタ３７と後リフレクタ３８の形状や構造が様々に変更される場合であっても、分割体３７ａ・３７ｂと後リフレクタ３８とを互いに位置決めした状態で適正に一体化することができる。 The front reflector 37 is configured by joining a plurality of divided bodies 37a and 37b, and a joint groove 52 and a joint wall 53 are formed on a joint surface of the rear reflector 38 with the front reflector 37. 37a and 37b are joined, the opening peripheral wall of the front reflector 37 is engaged and supported by the joining groove 52 and the joining wall 53, and further, the front engaging portion 51 and the rear engaging portion 54 are engaged in a concavo-convex manner to form the front reflector. 37 and the rear reflector 38 are integrated.

The rear reflector 38 and the rear reflector 38 can be firmly fastened and fixed. Further, even when the shapes and structures of the front reflector 37 and the rear reflector 38 are variously changed, the divided bodies 37a and 37b and the rear reflector 38 can be properly integrated with each other in a positioned state.

　吹出口１１に臨む導風路９の内部にイオン放出構造が設けたので、光源ユニット４から照射される赤外光と、イオン放出構造から放出されるマイナスイオンとを、乾燥風とともに髪へ送給することができる。従って、髪の乾燥を行いながら、マイナスイオンと結合した空気中の水分を髪に付着させて、髪が不必要に乾燥することを防止できる。また、電極ホルダー９１で支持される３個の放電電極９２と、横長長円状の筒壁９３の周囲に固定される対向電極９４とでイオン放出構造を構成したので、各放電電極９２と対向電極９４の間で活発にコロナ放電を生じさせて、より大量のマイナスイオンを乾燥風中に放出させることができる。 Since the ion emission structure is provided inside the air guide passage 9 facing the outlet 11, the infrared light emitted from the light source unit 4 and the negative ions emitted from the ion emission structure are sent to the hair together with the dry air. Can be paid. Therefore, while drying the hair, it is possible to prevent unnecessary drying of the hair by attaching moisture in the air combined with the negative ions to the hair. Further, the three discharge electrodes 92 supported by the electrode holder 91 and the counter electrode 94 fixed around the horizontally elongated oblong cylindrical wall 93 constitute an ion emission structure, and thus face each discharge electrode 92. A corona discharge can be actively generated between the electrodes 94 to discharge a larger amount of negative ions into the dry air.
　対向電極９４の前縁に複数の尖端放電部９４ａを形成したので、対向電極９４と放電電極９２の間のコロナ放電をさらに活発化して、マイナスイオンを安定した状態で効果的に生成することができる。 Since the plurality of tip discharge parts 94a are formed on the front edge of the counter electrode 94, the corona discharge between the counter electrode 94 and the discharge electrode 92 can be further activated, and negative ions can be effectively generated in a stable state. it can.
　吹出口１１と正対する側から見て、放電電極９２を光源ユニット４と本体ケース１の間に配置したので、イオン放出構造で生成されたマイナスイオンを、光源ユニット４と本体ケース１の間の導風路９に放出することができる。従って、マイナスイオンを送風ファン３から送給される乾燥風とともに吹出口１１から遠くまで送給することができる。 Since the discharge electrode 92 is arranged between the light source unit 4 and the main body case 1 when viewed from the side directly facing the outlet 11, the negative ions generated by the ion emission structure are generated between the light source unit 4 and the main body case 1. It can be discharged to the air guide passage 9. Therefore, negative ions can be sent to a distance from the outlet 11 together with the dry air sent from the blower fan 3.
　イオン放出構造を、光源ユニット４の光照射領域の外に位置する状態で、光源ユニット４と吹出口１１の間に配置したので、イオン放出構造で生成されたマイナスイオンを、光源ユニット４と吹出口１１の間の自由空間に放出して乾燥風とともに吹出口１１から送給することができる。また、光源ユニット４の光照射領域の外で、光源ユニット４と吹出口１１の間にイオン放出構造を配置したので、光源ユニット４から照射された光がイオン放出構造で遮られるのを防ぎながら、光源ユニット４と吹出口１１の間のスペースを利用してイオン放出構造を配置することができる。従って、イオン放出構造を設けることで本体ケース１の径方向寸法が大きくなるのを避けて、本体ケース１をコンパクト化することができる。 Since the ion emitting structure is located between the light source unit 4 and the outlet 11 in a state of being located outside the light irradiation region of the light source unit 4, the negative ions generated by the ion emitting structure are blown to the light source unit 4. It can be discharged into the free space between the outlets 11 and fed together with the dry air from the outlets 11. Further, since the ion emitting structure is arranged between the light source unit 4 and the outlet 11 outside the light emitting area of the light source unit 4, the light emitted from the light source unit 4 is prevented from being blocked by the ion emitting structure. The ion emission structure can be arranged by utilizing the space between the light source unit 4 and the outlet 11. Therefore, by providing the ion emitting structure, the main body case 1 can be prevented from increasing in size in the radial direction, and the main body case 1 can be made compact.
　風導筒７を、光源ユニット４と吹出口１１の間で前すぼまり状に形成したので、吹出口１１に向かって送給される乾燥風の流速を増強して、乾燥風中に放出されたマイナスイオンを、乾燥風とともに吹出口１１からさらに遠くまで送給することができる。 Since the air guide tube 7 is formed in the shape of the front constriction between the light source unit 4 and the air outlet 11, the flow velocity of the dry air sent toward the air outlet 11 is increased and the air is discharged into the dry air. The generated negative ions can be sent further away from the outlet 11 together with the dry air.
　本体ケース１を、風導筒７と、風導筒７に外嵌装着される外装筒８とで２重筒状に構成し、また、吹出口１１に臨む風導筒７の前部に、内凹み状のくびれ部３５を形成し、くびれ部３５の内面に吹出グリル２５を配置したので、２重筒状の風導筒７と外装筒８で本体ケース１の構造強度を増強して、衝撃吸収機能を向上することができる。また、２重筒状の風導筒７と外装筒８によって、本体ケース１全体の断熱機能を向上できるうえ、風導筒７の前部に形成したくびれ部３５の周囲の空気層によって断熱作用を強化できるので、高温になっている吹出グリル２５周辺のケース壁の熱が外装筒８に伝導するのをさらに確実に防止して、吹出口１１の近傍のケース壁が高温になるのを解消できる。 The main body case 1 is configured in a double-cylinder shape with an air guide tube 7 and an exterior tube 8 that is externally fitted and attached to the air guide tube 7, and at the front portion of the air guide tube 7 facing the air outlet 11. Since the inner recessed constricted portion 35 is formed and the blowout grill 25 is arranged on the inner surface of the constricted portion 35, the structural strength of the main body case 1 is increased by the double tubular air guide tube 7 and the exterior tube 8. The shock absorption function can be improved. Moreover, the heat insulating function of the entire main body case 1 can be improved by the double tube-shaped air guide tube 7 and the exterior tube 8, and the heat insulation effect is provided by the air layer around the constricted portion 35 formed in the front portion of the air guide tube 7. Therefore, it is possible to more reliably prevent the heat of the case wall around the blowout grill 25, which has become high temperature, from being transferred to the outer casing 8, and to prevent the case wall near the blowout port 11 from getting hot. it can.
　２分割された一対の半割体７ａ・７ｂで風導筒７を構成し、外装筒８を風導筒７に外嵌することにより、一対の半割体７ａ・７ｂを分離不能に保持できるようにした。また、外装筒８の前端内面に装着した吹出ケース５で、風導筒７と外装筒８を係合連結し、吹出ケース５をビス１９で外装筒８に締結固定するようにした。こうしたケース構造によれば、２重筒状の風導筒７と外装筒８を吹出ケース５で分離不能に保持固定して、基本的な構造体である風導筒７や外装筒８が遊動し、あるいはがたつくことを確実に防止できる。 The pair of half- split bodies 7a and 7b divided into two configures the air guide tube 7, and the exterior tube 8 is fitted onto the air guide tube 7, whereby the pair of half- split bodies 7a and 7b can be held inseparably. I did it. Further, the air guide case 7 and the outer case 8 are engaged and connected by the blow case 5 mounted on the inner surface of the front end of the outer case 8, and the blow case 5 is fastened and fixed to the outer case 8 with the screw 19. According to such a case structure, the air guide tube 7 and the outer case tube 8 which are in the form of a double tube are held and fixed inseparably by the blow-out case 5, and the air guide tube 7 and the outer case tube 8 which are the basic structures move freely. It is possible to reliably prevent rattling or rattling.
　吹出ケース５と風導筒７は吹出口連結構造で着脱可能に係合連結した。また吹出口連結構造は、吹出ケース５の後面に形成した複数個の係合脚５ｂと、風導筒７の前部外面に設けた複数の係合壁７ｃで構成し、吹出ケース５を回転操作することにより、係合脚５ｂと係合壁７ｃが互いに係合して、外装筒８と吹出ケース５と風導筒７の３者を一体化した。こうしたケース構造によれば、ビス１９を外装筒８から分離し、吹出ケース５を取外す向きに回転操作するだけで、外装筒８を風導筒７から分離し、さらに半割体７ａ・７ｂの一方を他方から取外すことで、本体ケース１に収容された光源ユニット４や送風ファン３などを露出させることができる。従って、ハロゲンランプ２８を交換し、あるいは送風ファン３のメンテナンスを行うような場合に、ケース構造をより少ない手間で簡単に分解してメンテナンス作業に要する手間を省くことができる。 The blow-out case 5 and the air guide tube 7 are detachably engaged and connected by a blow-out outlet connection structure. The outlet connection structure is composed of a plurality of engaging legs 5b formed on the rear surface of the blow case 5 and a plurality of engaging walls 7c provided on the outer surface of the front of the air guide tube 7, and the blow case 5 is rotated. By doing so, the engagement leg 5b and the engagement wall 7c are engaged with each other, and the exterior cylinder 8, the blowout case 5, and the air guide cylinder 7 are integrated. According to this case structure, the screw 19 is separated from the outer casing 8, and the outer casing 8 is separated from the air guide pipe 7 only by rotating the blowing case 5 in a direction to remove the blower casing 5. By removing one from the other, the light source unit 4, the blower fan 3 and the like housed in the main body case 1 can be exposed. Therefore, when the halogen lamp 28 is replaced or the blower fan 3 is maintained, the case structure can be easily disassembled with less labor to save the labor required for the maintenance work.
　また実施例１のドライヤーでは、リフレクタ２９の内部に導入した乾燥風でハロゲンランプ２８とリフレクタ２９を冷却しながら、乾燥風と共に第２通気口４２から漏れ出た光を防眩壁７５で遮蔽して、光が導風路９に沿って吹出口１１側へ向かって照射されることを防ぐことができる。例えば、第２通気口４２から漏れ出た光を、防眩壁７５で第２通気口４２の側へ向かって反射させ、あるいは防眩壁７５で散乱させ、さらに防眩壁７５で吸収し減衰させることができる。従って、リフレクタ２９の外へ漏れ出た光が吹出口１１から照射されるのを確実に防止して、髪乾燥時のユーザーに眩しさを感じさせることのないドライヤーを提供できる。 In the dryer of the first embodiment, while the halogen lamp 28 and the reflector 29 are cooled by the dry air introduced into the reflector 29, the light leaking from the second ventilation port 42 together with the dry air is blocked by the antiglare wall 75. Thus, it is possible to prevent the light from being emitted toward the outlet 11 side along the air guide passage 9. For example, light leaking from the second ventilation port 42 is reflected by the antiglare wall 75 toward the second ventilation port 42 side, or scattered by the antiglare wall 75, and further absorbed by the antiglare wall 75 and attenuated. Can be made Therefore, it is possible to reliably prevent the light leaking to the outside of the reflector 29 from being emitted from the outlet 11, and to provide a dryer that does not cause the user to feel dazzling when the hair is dried.
　また、防眩壁７５を筒状に構成し、防眩壁７５の筒壁後端を第２通気口４２の後開口縁より後方へ突設させるようにしたので、第２通気口４２の後開口縁から径方向に照射された光や、斜め前向きに照射された光を、防眩壁７５の筒壁内面で確実に遮蔽できる。光の一部は、防眩壁７５とリフレクタ２９の周面の間の空間を介して導風路９に照射されるが、防眩壁７５の筒壁後端を第２通気口４２の後開口縁より後方に位置したので、導風路９に照射された光は全て後向きに傾斜した状態で反射を繰り返す。従って、導風路９内の光が吹出口１１へ向かって照射されるのをさらに確実に防止できる。 In addition, since the antiglare wall 75 is formed in a tubular shape and the rear end of the tubular wall of the antiglare wall 75 is projected rearward from the rear opening edge of the second vent hole 42, the rear end of the second vent hole 42 is prevented. The light radiated from the opening edge in the radial direction and the light radiated obliquely forward can be reliably shielded by the inner surface of the cylindrical wall of the antiglare wall 75. Although a part of the light is radiated to the air guide passage 9 through the space between the antiglare wall 75 and the peripheral surface of the reflector 29, the rear end of the cylindrical wall of the antiglare wall 75 is located behind the second ventilation port 42. Since it is located behind the opening edge, all the light emitted to the air guide passage 9 is repeatedly reflected in a state of being inclined rearward. Therefore, it is possible to more reliably prevent the light in the air guide passage 9 from being emitted toward the air outlet 11.
　前リフレクタ３７と後リフレクタ３８でリフレクタ２９を構成し、前リフレクタ３７の前部に配置したフィルタ３０をフィルタ支持構造５９で固定するようにした。また、フィルタ支持構造５９は、前リフレクタ３７に形成したフィルタ受座４１と、同受座４１と協同してフィルタ３０を挟持固定する押えリング６０を備えるようにした。これによれば、フィルタ３０をフィルタ受座４１に組み、押えリング６０を前リフレクタ３７の前部周面に外嵌し固定することで、フィルタ３０を前リフレクタ３７に簡単に組付けて、分離不能にしっかりと固定することができる。 The front reflector 37 and the rear reflector 38 constitute the reflector 29, and the filter 30 arranged in the front part of the front reflector 37 is fixed by the filter support structure 59. Further, the filter support structure 59 is provided with the filter seat 41 formed on the front reflector 37, and the holding ring 60 for sandwiching and fixing the filter 30 in cooperation with the seat 41. According to this, by assembling the filter 30 to the filter seat 41 and externally fitting and fixing the pressing ring 60 to the front peripheral surface of the front reflector 37, the filter 30 is easily assembled to the front reflector 37 and separated. It can be securely fixed improperly.
　送風ファン３から送給された乾燥風は、第１通気口４８からリフレクタ２９の内部に導入されて第２通気口４２から送出される。これによれば、リフレクタ２９の内部における乾燥風の流れの方向と、送風ファン３から送給された乾燥風の導風路９における流れの方向を一致させることができるので、乾燥風の一部をリフレクタ２９の内部に確実に導入して、光源ユニット４とリフレクタ２９の冷却を適確に行うことができる。 The dry air sent from the blower fan 3 is introduced into the reflector 29 from the first vent 48 and sent out from the second vent 42. According to this, the flow direction of the dry air inside the reflector 29 and the flow direction of the dry air sent from the blower fan 3 in the air guide passage 9 can be made to coincide with each other. Can be reliably introduced into the reflector 29, and the light source unit 4 and the reflector 29 can be cooled appropriately.
　また、防眩壁７５と第２通気口４２の間に通気通路７６を形成し、同通路７６の前端の通路端壁７７と防眩壁７５で挟まれる内隅部分に、乾燥風を後向きに反転案内する後反転案内面７８を形成するようにした。このように、防眩壁７５と通路端壁７７の間の内隅部分に後反転案内面７８が形成されていると、第２通気口４２を通過した後の乾燥風を後反転案内面７８で通気通路７６の後開口へ向かって円滑に反転案内することができる。従って、通気通路７６における乾燥風の流れを整然とした流れにして、光源ユニット４とリフレクタ２９を冷却した後の乾燥風の一部が第２通気口４２や通気通路７６で滞留するのを解消できる。 Further, a ventilation passage 76 is formed between the antiglare wall 75 and the second ventilation port 42, and dry air is directed rearward to an inner corner portion sandwiched between the passage end wall 77 and the antiglare wall 75 at the front end of the passage 76. After the reverse guide, the reverse guide surface 78 is formed. In this way, when the rear reversal guide surface 78 is formed at the inner corner portion between the antiglare wall 75 and the passage end wall 77, the dry wind after passing through the second ventilation port 42 is guided to the rear reversal guide surface 78. Thus, it is possible to smoothly perform the inversion guide toward the rear opening of the ventilation passage 76. Therefore, the flow of the dry air in the ventilation passage 76 can be made to be an orderly flow, and a part of the dry air after cooling the light source unit 4 and the reflector 29 can be prevented from staying in the second ventilation port 42 or the ventilation passage 76. ..
　加えて、防眩壁７５の後端部に、通気通路７６から流出する乾燥空気を前向きに反転案内する前反転案内面７９を形成したので、通気通路７６から流出した乾燥空気を防眩壁７５の外面側へ向かって円滑に反転案内させて、導風路９を流動する乾燥風に合流させることができる。 In addition, since the front reversing guide surface 79 is formed at the rear end of the antiglare wall 75 to guide the dry air flowing out of the ventilation passage 76 in the forward direction, the dry air flowing out of the ventilation passage 76 is prevented. It is possible to smoothly invert and guide the air toward the outer surface side and to join the dry air flowing in the air guide passage 9.
　空気の吸込口１０は、上記の各実施例のように本体ケース１の後端背面に形成される形態に加え、本体ケース１の後端背面は塞がれ同ケース１の後端周側面に形成される形態であってもよい。本発明に係る導風路９の一端（後端）に設けられる吸込口１０とは、これら形態を含む意味である。本体ケース１の後端周側面に吸込口１０を設けた場合には、送風ファン３は、プロペラ型ないしインペラ型の軸流ファン、求心ファンなどで構成する。リフレクタ２９の形状は、乾燥対象への赤外光の照射態様により適宜変更することができる。本発明における光照射装置は、毛髪を乾燥対象とするヘアードライヤーに限らず、手足、爪などの身体部位、あるいは人用に限らず犬や猫など動物用のドライヤーにも適用でき、また、衣類用の衣類乾燥器にも適用できる。さらに、本発明の光照射装置は、乾燥対象に対して光を照射する機器であれば、例えば、毛髪を乾燥しながらカール状、あるいはストレート状に整形することができるドライヤーの機能を備えたヘアーアイロンや、光を患部に照射する光治療器にも適用できる。光源２８はハロゲンランプ以外に、白熱ランプ、キセノンランプ、メタルハライドランプ、ＬＥＤなどであってもよい。 The air suction port 10 is formed on the rear end rear surface of the main body case 1 as in each of the above-mentioned embodiments, and the rear end rear surface of the main body case 1 is closed to the rear end peripheral side surface of the same case 1. It may be formed. The suction port 10 provided at one end (rear end) of the air guide passage 9 according to the present invention is meant to include these forms. When the suction port 10 is provided on the side surface of the rear end of the main body case 1, the blower fan 3 is composed of a propeller-type or impeller-type axial fan, a centripetal fan, or the like. The shape of the reflector 29 can be appropriately changed depending on the irradiation mode of infrared light to the drying target. The light irradiation device in the present invention is not limited to a hair dryer for drying hair, but can be applied to body parts such as limbs and nails, or a dryer for animals such as dogs and cats not only for humans, but also for clothing. It can also be applied to clothes dryers for clothing. Further, the light irradiation device of the present invention is a device that irradiates light to a drying target, for example, a hair having a function of a drier that can shape the curl or straight while drying the hair. It can also be applied to irons and phototherapy devices that irradiate the affected area with light. The light source 28 may be an incandescent lamp, a xenon lamp, a metal halide lamp, an LED, etc., in addition to the halogen lamp.
