Description

本発明は、吹出ノズルを備えているヘアードライヤー、なかでも形態を切り換えることにより吹出風の状態を収束し、あるいは拡散できる吹出ノズルに関する。 The present invention relates to a hair dryer having a blowing nozzle, and more particularly to a blowing nozzle capable of converging or diffusing the state of blowing air by switching the form.

この種のヘアードライヤーは、例えば特許文献１に公知である。そこでは、ドライヤー本体の吹出口に吹出ノズルを装着し、吹出ノズルの内部にシャッター筒を配置している。吹出ノズルの筒周壁の左右には噴出口が開口してあり、シャッター筒の筒壁にも同様の通気窓が開口してある。シャッター筒を回転操作して、噴出口をシャッター筒で塞いだ状態では、吹出風を吹出ノズルの先端部分からのみ収束した状態で吹き出すことができる。シャッター筒をさらに回転操作して、通気窓を噴出口に臨ませた状態では、吹出ノズルの先端部分と、左右の噴出口との双方から、吹出風を拡散した状態で吹き出すことができる。 This type of hair dryer is known, for example, from US Pat. There, a blow nozzle is attached to the blow outlet of the dryer body, and a shutter cylinder is arranged inside the blow nozzle. Jet outlets are opened on the left and right of the cylinder peripheral wall of the blowout nozzle, and a similar ventilation window is also opened on the cylinder wall of the shutter cylinder. In a state where the shutter cylinder is rotated and the outlet is closed with the shutter cylinder, the blown air can be blown out in a state of being converged only from the tip portion of the blowing nozzle. In a state where the shutter cylinder is further rotated and the ventilation window faces the jet port, the blown air can be blown out from both the tip portion of the blow nozzle and the left and right jet ports.

特許文献２においては、吹出ノズルをドライヤー本体の吹出口に対して偏心回転させて、吹出風の状態を変更できるようにしている。詳しくは、ドライヤー本体の吹出口の偏心位置で吹出ノズルの回転軸を軸支し、吹出ノズルをモーター動力で回転駆動することにより、吹出ノズルを回転軸の周りに偏心回転させて、吹出風の一部を広い範囲にわたって吹き出すようにしている。 In Patent Document 2, the blowout nozzle is eccentrically rotated with respect to the blower outlet of the dryer body so that the state of the blowout air can be changed. Specifically, the rotation axis of the blow nozzle is pivotally supported at the eccentric position of the blower outlet of the dryer body, and the blow nozzle is rotated around the rotation axis by rotating the blow nozzle with motor power to A part is blown out over a wide range.

特開平０５−１３０９１５号公報（段落番号００１３〜００１４、図３）Japanese Patent Laid-Open No. 05-130915 (paragraph numbers 0013 to 0014, FIG. 3) 特公昭５８−１１８７１１号公報（第２頁左下欄１７行〜第２頁右欄７行、第１図）Japanese Examined Patent Publication No. 58-118711 (page 2, lower left column, line 17 to page 2, right column, line 7, line 1)

特許文献１のヘアードライヤーによれば、シャッター筒で吹出ノズルの噴出口を開閉することにより、吹出風を収束する状態と、拡散する状態とに変更できる。しかし、吹出風を吹出ノズルの筒壁の両側に開口した噴出口から送出するので、噴出口から送出された吹出風が髪に向かって直進しにくく、そのため乾燥風の一部が不必要に拡散して無駄になりやすい。 According to the hair dryer of Patent Literature 1, the blower air can be changed into a state where the blown air is converged and a state where the air is diffused by opening and closing the outlet of the blowout nozzle with the shutter cylinder. However, since the blowing air is sent out from the jet openings opened on both sides of the cylindrical wall of the blowing nozzle, the blowing air sent out from the jet nozzle is difficult to go straight to the hair, and therefore part of the drying air is unnecessarily diffused. And it is easy to be wasted.

また、特許文献２のヘアードライヤーの場合には、吹出ノズルを偏心回転させて、ドライヤー本体の吹出口から送出される乾燥風の一部を、吹出ノズルを介して送出する。しかし殆どの場合、吹出ノズルの入口がドライヤー本体の吹出口に対して位置ずれした状態になる。そのため、乾燥風の殆どはドライヤー本体の吹出口から直接送出されることになり、偏心回転する吹出ノズルによる乾燥風の拡散を効果的に行なえない。また、乾燥風を収束した状態で送出することもできない。 Moreover, in the case of the hair dryer of patent document 2, a blowing nozzle is eccentrically rotated and a part of drying wind sent from the blower outlet of a dryer main body is sent through a blower nozzle. However, in most cases, the inlet of the blowout nozzle is displaced with respect to the blower outlet of the dryer body. For this reason, most of the drying air is directly sent out from the outlet of the dryer body, and the drying air cannot be effectively diffused by the blowing nozzle that rotates eccentrically. Also, it cannot be sent out with the drying air converged.

本発明の目的は、ドライヤー本体の吹出口から送出される乾燥風を効果的に収束し、あるいは効果的に拡散できる吹出ノズルを備えたヘアードライヤーを提供することにある。
本発明の目的は、吹出ノズルを収束姿勢と拡散姿勢とに変更するための構造を簡素化し、さらに吹出ノズルの姿勢変更操作を簡便化できるヘアードライヤーを提供することにある。 The objective of this invention is providing the hair dryer provided with the blowing nozzle which can converge effectively the dry wind sent from the blower outlet of a dryer main body, or can be spread | diffused effectively.
An object of the present invention is to provide a hair dryer that simplifies the structure for changing the blowing nozzle to the convergence posture and the diffusion posture, and further simplifies the posture changing operation of the blowing nozzle.

本発明に係るヘアードライヤは、ドライヤー本体１の吹出口８に吹出ノズル１１を装着する。吹出ノズル１１の先端のノズル開口に、複数の山形の収束片２４・３２を周回状に形成する。収束片２４・３２の先端の山部２４ａ・３２ａと、隣接する山部２４ａ・３２ａの間に形成される谷部２４ｂ・３２ｂとは、交互に、かつ周方向へ等間隔おきに形成する。 In the hair dryer according to the present invention, the blow nozzle 11 is attached to the blow outlet 8 of the dryer main body 1. A plurality of angled converging pieces 24 and 32 are formed in a circular shape in the nozzle opening at the tip of the blow-out nozzle 11. The crests 24a and 32a at the tips of the converging pieces 24 and 32 and the troughs 24b and 32b formed between the adjacent crests 24a and 32a are alternately formed at equal intervals in the circumferential direction.

図１に示すように、吹出ノズル１１は、内側ノズル２１と外側ノズル２２とで２重筒状に構成する。内側ノズル２１および外側ノズル２２の前側のノズル開口のそれぞれに、複数の山形の収束片２４・３２を周回状に形成する。内側ノズル２１と外側ノズル２２とは相対回転可能に構成する。内外の両ノズル２１・２２を相対回転操作して、吹出ノズル１１の形態を、内側ノズル２１の収束片２４と外側ノズル２２の収束片３２とが内外に重さなる拡散姿勢と、内側ノズル２１の収束片２４と外側ノズル２２の収束片３２とが周方向へ隣接する収束姿勢とに切り換え可能とする。 As shown in FIG. 1, the blowout nozzle 11 includes a double cylinder with an inner nozzle 21 and an outer nozzle 22. A plurality of mountain-shaped converging pieces 24 and 32 are formed in a circular shape in each of the nozzle openings on the front side of the inner nozzle 21 and the outer nozzle 22. The inner nozzle 21 and the outer nozzle 22 are configured to be relatively rotatable. Both the inner and outer nozzles 21 and 22 are operated to rotate relative to each other, and the form of the blowout nozzle 11 is changed to a diffusion posture in which the converging piece 24 of the inner nozzle 21 and the converging piece 32 of the outer nozzle 22 overlap inside and outside, and the inner nozzle 21. The converging piece 24 and the converging piece 32 of the outer nozzle 22 can be switched to a converging posture adjacent in the circumferential direction.

内側ノズル２１と外側ノズル２２のそれぞれを、断面円形の筒基部２３・３１と、筒基部２３・３１に連続してノズル先端へ向かって突設される収束片２４・３２とで構成する。筒基部２３・３１および収束片２４・３２のうち、少なくとも収束片２４・３２をノズル先端へ向かって先すぼまり状の壁で形成する。 Each of the inner nozzle 21 and the outer nozzle 22 includes a cylindrical base portion 23/31 having a circular cross section, and converging pieces 24/32 projecting from the cylindrical base portion 23/31 toward the tip of the nozzle. Of the tube bases 23 and 31 and the converging pieces 24 and 32, at least the converging pieces 24 and 32 are formed by a conical wall that is tapered toward the tip of the nozzle.

内側ノズル２１の収束片２４の山部２４ａの先端位置と、外側ノズル２２の収束片３２の山部３２ａの先端位置とは、吹出ノズル１１の筒軸中心と直交する垂直平面に位置させる。 The front end position of the crest 24 a of the converging piece 24 of the inner nozzle 21 and the front end position of the crest 32 a of the converging piece 32 of the outer nozzle 22 are positioned on a vertical plane orthogonal to the center of the cylinder axis of the blowing nozzle 11.

ドライヤー本体１の吹出口８から吹出ノズル１１の先端までの距離をノズル長Ｌとするとき、内側ノズル２１の収束片２４の谷部２４ｂの底位置と、外側ノズル２２の収束片３２の谷部３２ｂの底位置のそれぞれを、ノズル長Ｌの略半分の位置に位置させる。 When the distance from the outlet 8 of the dryer body 1 to the tip of the outlet nozzle 11 is the nozzle length L, the bottom position of the valley 24b of the converging piece 24 of the inner nozzle 21 and the trough of the converging piece 32 of the outer nozzle 22 Each of the bottom positions of 32b is positioned at a position approximately half of the nozzle length L.

内側ノズル２１の収束片２４と外側ノズル２２の収束片３２とを同形に形成し、吹出ノズル１１を拡散姿勢にした状態において収束片２４・３２を内外に近接ないし密着させる。 The converging piece 24 of the inner nozzle 21 and the converging piece 32 of the outer nozzle 22 are formed in the same shape, and the converging pieces 24 and 32 are brought close to or in close contact with each other in a state where the blowing nozzle 11 is in the diffusion posture.

内側ノズル２１の収束片２４と外側ノズル２２の収束片３２との形成個数を同じにする。さらに、両収束片２４・３２を同形で同大に形成する。 The number of forming the converging pieces 24 of the inner nozzle 21 and the converging pieces 32 of the outer nozzle 22 is the same. Further, both converging pieces 24 and 32 are formed in the same shape and the same size.

内側ノズル２１をドライヤー本体１の吹出口８に連結する。内側ノズル２１に連結した外側ノズル２２を、内側ノズル２１で回転自在に支持する。 The inner nozzle 21 is connected to the outlet 8 of the dryer body 1. The outer nozzle 22 connected to the inner nozzle 21 is rotatably supported by the inner nozzle 21.

内側ノズル２１の筒基部２３に設けた連結筒２５を、ドライヤー本体１の吹出口８の外周面に設けた筒状の連結部１２に圧嵌係合する。外側ノズル２２の筒基部３１の開口内面に設けた連結爪３３を、内側ノズル２１の筒基部２３の外面に設けた連結溝２６に圧嵌係合して、外側ノズル２２を内側ノズル２１で回転自在に支持する。内側ノズル２１の連結溝２６に、外側ノズル２２の連結爪３３と係脱する節度体３６を設ける。 The connecting cylinder 25 provided in the cylinder base 23 of the inner nozzle 21 is press-fitted and engaged with the cylindrical connecting part 12 provided on the outer peripheral surface of the air outlet 8 of the dryer body 1. The coupling claw 33 provided on the inner surface of the opening of the cylinder base 31 of the outer nozzle 22 is press-fitted into the coupling groove 26 provided on the outer surface of the cylinder base 23 of the inner nozzle 21, and the outer nozzle 22 is rotated by the inner nozzle 21. Support freely. A moderation body 36 is provided in the connection groove 26 of the inner nozzle 21 so as to engage with and disengage from the connection claw 33 of the outer nozzle 22.

ドライヤー本体１の筒状の連結部１２に臨んで、ドライヤー本体１の後方へ向かって凹む回止め凹部１６を設ける。内側ノズル２１の連結筒２５の開口縁に、前記回止め凹部１６と係合する回止め片２８を膨出形成する。内側ノズル２１の連結筒２５を、ドライヤー本体１の連結部１２に連結した状態において、回止め片２８を回止め凹部１６で回動不能に受け止める。 Faced to the cylindrical connecting portion 12 of the dryer body 1, a rotation stopper recess 16 that is recessed toward the rear of the dryer body 1 is provided. At the opening edge of the connecting cylinder 25 of the inner nozzle 21, a rotation stopping piece 28 that engages with the rotation stopping recess 16 is formed to bulge. In a state where the connecting cylinder 25 of the inner nozzle 21 is connected to the connecting portion 12 of the dryer main body 1, the rotation stopping piece 28 is received by the rotation stopping recess 16 so as not to be rotatable.

内側ノズル２１の厚み寸法を、外側ノズル２２の厚み寸法より小さく設定する。 The thickness dimension of the inner nozzle 21 is set smaller than the thickness dimension of the outer nozzle 22.

本発明においては、ドライヤー本体１の吹出口８に装着した吹出ノズル１１の先端に、複数の山形の収束片２４・３２を周回状に形成し、その山部２４ａ・３２ａと谷部２４ｂ・３２ｂとを交互に、しかも周方向へ等間隔に形成した。このように、吹出ノズル１１の先端に山形の収束片２４・３２を周回状に形成すると、誤って頭皮の近傍にノズル開口を位置させた場合であっても、温風の一部を各収束片２４・３２の間の谷部２４ｂ・３２ｂから逃がすことができるので、髪が過熱されて傷むのをよく防止できる。加えて、ノズル開口に配置した山形の収束片２４・３２がデザイン効果を発揮して、吹出ノズル１１のデザイン性を向上できる。 In the present invention, a plurality of mountain-shaped converging pieces 24 and 32 are formed in a circular shape at the tip of the blowout nozzle 11 attached to the blowout port 8 of the dryer body 1, and the peaks 24 a and 32 a and valleys 24 b and 32 b are formed. And at equal intervals in the circumferential direction. In this way, when the angle-shaped converging pieces 24 and 32 are formed in a circular shape at the tip of the blowing nozzle 11, even if the nozzle opening is mistakenly positioned in the vicinity of the scalp, a part of the hot air is converged. Since it can escape from the troughs 24b and 32b between the pieces 24 and 32, it can prevent well that hair is overheated and damaged. In addition, the angle-shaped converging pieces 24 and 32 arranged at the nozzle opening exhibit a design effect, and the design of the blowout nozzle 11 can be improved.

内側ノズル２１と外側ノズル２２とで吹出ノズル１１を２重筒状に構成し、それぞれのノズル開口に収束片２４・３２を設けると、内外の両ノズル２１・２２を相対回転操作することにより、拡散姿勢と収束姿勢とに切り換えることができる。拡散姿勢においては、収束片２４・３２が内外に重さなって、内側ノズル２１の収束片２４のみで吹出ノズル１１内の乾燥風を絞る。また、収束姿勢においては、収束片２４・３２を周方向へ隣接させて、全ての収束片２４・３２で吹出ノズル１１内の乾燥風を絞る。このように、乾燥風に作用する収束片２４・３２の数を大小に変更して送出状態を変更すると、乾燥風を明確に絞り込み、あるいは絞り込み作用を大幅に緩和して、広い範囲にわたって拡散させることができる。したがって、乾燥風を効果的に収束し、あるいは効果的に拡散できる吹出ノズル１１が得られる。 When the blowing nozzle 11 is configured in a double cylinder shape with the inner nozzle 21 and the outer nozzle 22, and the converging pieces 24 and 32 are provided in the respective nozzle openings, the inner and outer nozzles 21 and 22 are relatively rotated, It is possible to switch between a diffusion posture and a convergence posture. In the diffusion posture, the converging pieces 24 and 32 are overlapped on the inside and outside, and the drying air in the blowing nozzle 11 is squeezed only by the converging piece 24 of the inner nozzle 21. In the convergence posture, the converging pieces 24 and 32 are adjacent to each other in the circumferential direction, and the drying air in the blowing nozzle 11 is squeezed by all the converging pieces 24 and 32. As described above, when the number of the converging pieces 24 and 32 acting on the drying air is changed to a large or small size and the delivery state is changed, the drying air is clearly narrowed or the narrowing action is greatly relaxed and diffused over a wide range. be able to. Accordingly, it is possible to obtain the blowout nozzle 11 that can effectively converge or effectively diffuse the dry air.

断面円形の筒基部２３・３１と収束片２４・３２とで内外の両ノズル２１・２２を構成し、少なくとも収束片２４・３２をノズル先端へ向かって先すぼまり状に形成すると、両ノズル２１・２２による乾燥風の絞り込みをさらに確実に行なえる。したがって、両ノズル２１・２２を収束姿勢にした場合と、拡散姿勢にした場合とで、乾燥風の送出状態を明確に異ならせて、使用者の使用目的に適合した状態で乾燥風を送出できる。また、両ノズル２１・２２を収束姿勢にした状態においては、乾燥風を的確に収束して、風量が多くしかも指向性の強い乾燥風を髪に送給できる。 When both the inner and outer nozzles 21 and 22 are formed by the cylindrical base portions 23 and 31 having a circular cross section and the converging pieces 24 and 32, and at least the converging pieces 24 and 32 are formed in a tapered shape toward the nozzle tip, both nozzles are formed. The drying air can be narrowed down more reliably by 21 and 22. Therefore, when the nozzles 21 and 22 are set to the converged posture and when the nozzles 21 and 22 are set to the diffusing posture, it is possible to send the dry air in a state suitable for the user's purpose of use by clearly changing the dry air sending state. . Further, in a state where the nozzles 21 and 22 are in the convergent posture, the drying air is accurately converged, and the drying air having a large air volume and strong directivity can be supplied to the hair.

内外両ノズル２１・２２の収束片２４・３２の山部２４ａ・３２ａの先端位置を、筒軸中心と直交する垂直平面に位置させると、両ノズル２１・２２を収束姿勢にした状態において、吹出ノズル１１内の乾燥風を各収束片２４・３２で最後まで均等に絞ることができる。したがって、乱れが少なく、しかも指向性の強い乾燥風を髪に吹き付けることができる。 When the tip positions of the crests 24a and 32a of the converging pieces 24 and 32 of the inner and outer nozzles 21 and 22 are positioned on a vertical plane perpendicular to the center of the cylinder axis, the nozzles 21 and 22 are blown out in a converging posture. The drying air in the nozzle 11 can be uniformly squeezed to the end by the convergent pieces 24 and 32. Therefore, it is possible to blow dry air with little turbulence and strong directivity on the hair.

内側ノズル２１の収束片２４の谷部２４ｂの底位置と、外側ノズル２２の収束片３２の谷部３２ｂの底位置のそれぞれを、ノズル長Ｌの略半分の位置に位置させると、拡散姿勢と収束姿勢における乾燥風の状態をさらに明確に異ならせることができる。したがって、乾燥風を広い範囲に拡散送給しながら整髪し、あるいは乾燥風を集中的に収束送給して髪の乾燥を促進するなど、使用目的に適合した状態で乾燥風を送出できる。 When each of the bottom position of the valley portion 24b of the converging piece 24 of the inner nozzle 21 and the bottom position of the valley portion 32b of the converging piece 32 of the outer nozzle 22 is located at a position substantially half of the nozzle length L, The state of the drying air in the convergent posture can be made more clearly different. Therefore, it is possible to send the drying air in a state suitable for the purpose of use, such as styling while diffusing and feeding the drying air over a wide range, or concentrating and feeding the drying air to promote hair drying.

内外の収束片２４・３２を同形に形成し、吹出ノズル１１を拡散姿勢にした状態において両収束片２４・３２を内外に近接ないし密着させると、両収束片２４・３２が協同して外力や衝撃力に対抗でき、その分だけ吹出ノズル１１の構造強度を向上できる。とくに、収束片２４・３２が山形や花弁形に形成してある場合には先端部分を欠損しやすいが、両収束片２４・３２の協同作用で外力や衝撃力を受け止めることにより、先端部分の破損や変形をよく防止できる。 When the inner and outer converging pieces 24 and 32 are formed in the same shape and the converging pieces 24 and 32 are brought close to or in close contact with the inside and outside in a state where the blowing nozzle 11 is in the diffusion posture, the converging pieces 24 and 32 cooperate with each other to generate external force or The impact strength can be countered, and the structural strength of the blowing nozzle 11 can be improved accordingly. In particular, when the converging pieces 24 and 32 are formed in a mountain shape or a petal shape, the tip portion is likely to be lost, but by receiving external force or impact force by the cooperative action of the converging pieces 24 and 32, the tip portion Damage and deformation can be well prevented.

内外の収束片２４・３２の形成個数を同じにし、さらに、両収束片２４・３２を同形で同大に形成すると、吹出ノズル１１を拡散姿勢にした場合と収束姿勢にした場合とで、各収束片２４・３２で覆われる面積の差を、概ね１対２と大きな差にすることができる。したがって、各姿勢における乾燥風の状態を明確に異ならせて、使用者の使用目的に適合した状態で乾燥風を送出できる。 When the number of formed inner and outer converging pieces 24 and 32 is made the same, and when both converging pieces 24 and 32 are formed in the same shape and the same size, each of the blowing nozzle 11 is in the diffusion posture and in the converging posture. The difference in the area covered by the convergence pieces 24 and 32 can be set to a large difference of about 1 to 2. Therefore, the state of the dry air in each posture can be clearly changed, and the dry air can be sent out in a state suitable for the user's purpose of use.

内側ノズル２１をドライヤー本体１の吹出口８に連結し、外側ノズル２２を内側ノズル２１で回転自在に支持すると、外側ノズル２２を直接回転操作することにより吹出ノズル１１の姿勢を変更できるので、姿勢変更のための構造を簡素化できる。内側ノズル２１を回転操作する場合には、内側ノズル２１に操作部材を設け、操作部材を外側ノズル２２の外面に露出させる必要があるが、このような構造を省略できるからである。また、外側ノズル２２の任意の部分を掴んで回転操作することにより吹出ノズル１１の姿勢を変更できるので、吹出ノズル１１の姿勢変更を簡便に行なえる。さらに、内側ノズル２１に比べて温風に晒される機会の少ない外側ノズル２２を操作して姿勢を変更するので、熱い思いをすることもなく吹出ノズル１１の姿勢を的確に変更できる。 If the inner nozzle 21 is connected to the outlet 8 of the dryer body 1 and the outer nozzle 22 is rotatably supported by the inner nozzle 21, the posture of the outlet nozzle 11 can be changed by directly rotating the outer nozzle 22, The structure for change can be simplified. When the inner nozzle 21 is rotated, it is necessary to provide an operation member on the inner nozzle 21 and expose the operation member to the outer surface of the outer nozzle 22 because such a structure can be omitted. Moreover, since the attitude | position of the blowing nozzle 11 can be changed by grasping | ascertaining the arbitrary part of the outer side nozzle 22, and rotating, the attitude | position change of the blowing nozzle 11 can be performed simply. Furthermore, since the posture is changed by operating the outer nozzle 22 which is less exposed to hot air than the inner nozzle 21, the posture of the blowout nozzle 11 can be changed accurately without feeling hot.

内側ノズル２１の連結筒２５をドライヤー本体１の連結部１２に圧嵌係合し、外側ノズル２２の連結爪３３を内側ノズル２１の連結溝２６に対して回転自在に圧嵌係合すると、内側ノズル２１を操作するだけで、吹出ノズル１１のドライヤー本体１に対する着脱を容易に行なえる。また、内側ノズル２１を着脱する際に、外側ノズル２２が内側ノズル２１から分離するのを防止して、吹出ノズル１１の装着および取り外し操作を簡便化できる。さらに、内側ノズル２１の連結溝２６に、外側ノズル２２の連結爪３３と係脱する節度体３６を設けることにより、外側ノズル２２を収束姿勢と拡散姿勢において節度体３６で位置決めし、その状態を保持できる。したがって、吹出ノズル１１の姿勢を収束姿勢にし、あるいは拡散姿勢にするときの姿勢の切り換えを常に適正に行なえる。また、ヘアードライヤーの使用時に吹出ノズル１１の姿勢が不用意に切り換わるのを防止して、使用目的に適合した状態で乾燥風を送出できる。 When the connecting cylinder 25 of the inner nozzle 21 is press-fitted and engaged with the connecting portion 12 of the dryer body 1 and the connecting claw 33 of the outer nozzle 22 is press-fitted and engaged with the connecting groove 26 of the inner nozzle 21, The spray nozzle 11 can be easily attached to and detached from the dryer body 1 simply by operating the nozzle 21. Moreover, when attaching / detaching the inner nozzle 21, the outer nozzle 22 is prevented from being separated from the inner nozzle 21, and the mounting and removing operations of the blowing nozzle 11 can be simplified. Further, by providing a moderation body 36 that engages and disengages with the connection claw 33 of the outer nozzle 22 in the connection groove 26 of the inner nozzle 21, the outer nozzle 22 is positioned by the moderation body 36 in the converging posture and the diffusion posture. Can hold. Therefore, it is possible to always properly switch the posture when the blowing nozzle 11 is set to the convergence posture or the diffusion posture. Moreover, it can prevent that the attitude | position of the blowing nozzle 11 switches carelessly at the time of use of a hair dryer, and can send dry wind in the state suitable for the intended purpose.

ドライヤー本体１の連結部１２に回止め凹部１６を設け、この回止め凹部１６で内側ノズル２１の連結筒２５に設けた回止め片２８を受け止めると、ドライヤー本体１に装着した吹出ノズル１１が不用意に回転するのを規制できる。また、内側ノズル２１をドライヤー本体１に組み付ける際には、回止め片２８を回止め凹部１６で案内して、吹出ノズル１１の装着姿勢を適正化し位置決めできるので、吹出ノズル１１のドライヤー本体１に対する取り付けをさらに容易に行なえる。 When the rotation recess 16 is provided in the connecting portion 12 of the dryer main body 1 and the rotation stopper 28 provided in the connection cylinder 25 of the inner nozzle 21 is received by the rotation recess 16, the blowout nozzle 11 attached to the dryer main body 1 is not used. It is possible to regulate the ready rotation. Further, when the inner nozzle 21 is assembled to the dryer main body 1, the rotation stopper 28 can be guided by the rotation concave portion 16 so that the mounting posture of the blowing nozzle 11 can be optimized and positioned. Installation is easier.

内側ノズル２１の厚み寸法を、外側ノズル２２の厚み寸法より小さく設定すると、温風を送給する使用状態において、常に温風に晒される内側ノズル２１の熱膨張量を小さくできる。したがって、熱膨張した内側ノズル２１の外面が、外側ノズル２２の内面を強圧するのを抑止して、長時間にわたってヘアードライヤーを使用するような場合であっても、外側ノズル２２を円滑に回転操作できる。 When the thickness dimension of the inner nozzle 21 is set to be smaller than the thickness dimension of the outer nozzle 22, the amount of thermal expansion of the inner nozzle 21 that is always exposed to the warm air can be reduced in a use state where warm air is supplied. Therefore, the outer surface of the inner nozzle 21 that has been thermally expanded is prevented from strongly pressing the inner surface of the outer nozzle 22, and the outer nozzle 22 is smoothly rotated even when a hair dryer is used for a long time. it can.

図１ないし図８は本発明に係るヘアードライヤの実施例を示す。図２においてヘアードライヤは、横長筒状のドライヤー本体１と、ドライヤー本体１の後部寄り下面に連結されるグリップ２とを備えている。ドライヤー本体１の内部には、軸流型の送風ファン３と、ファン駆動用のモーター４と、送風ファン３から送給される空気を加熱するヒーター５などが配置してある。なお、本発明における前後、左右、上下とは、図２に示す交差矢印と、各矢印の近傍に表記した前後、左右、上下の表示に従う。 1 to 8 show an embodiment of a hair dryer according to the present invention. In FIG. 2, the hair dryer includes a horizontally long dryer body 1 and a grip 2 connected to the lower surface of the dryer body 1 near the rear. Inside the dryer main body 1, an axial flow type blower fan 3, a motor 4 for driving the fan, a heater 5 for heating air supplied from the blower fan 3, and the like are arranged. In the present invention, “front / rear”, “left / right”, and “upper / lower” follow the cross arrows shown in FIG.

グリップ２の前面にはスイッチノブ６が設けてあり、このスイッチノブ６をオフ位置から上向きにスライド操作することにより、第１から第３の各運転モードに切り換えることができる。第１運転モードではモーター４のみを高速駆動して、常温の冷風を送給する。第２運転モードでは、モーター４およびヒーター５を同時に駆動するが、モーター４は半速でさらにヒーター５は半分の熱出力で作動させて、比較的低温で低速の温風を送給する。第３運転モードでは、モーター４を高速駆動し、さらにヒーター５を最大の熱出力で作動させて、高温で高速の温風を送給する。送風ファン３を駆動する状態では、ドライヤー本体１の後端の吸込グリル７から外部空気が吸い込まれ、送風ファン３で加圧されたのち、ドライヤー本体１の前端の吹出口８から吹き出される。この吹出口８に、本発明に係る吹出ノズル１１が着脱自在に装着してある。 A switch knob 6 is provided on the front surface of the grip 2, and the switch knob 6 can be switched to the first to third operation modes by sliding the switch knob 6 upward from the off position. In the first operation mode, only the motor 4 is driven at high speed, and cold air at normal temperature is supplied. In the second operation mode, the motor 4 and the heater 5 are driven at the same time. The motor 4 is operated at half speed and the heater 5 is operated at half heat output to supply hot air at a relatively low temperature and low speed. In the third operation mode, the motor 4 is driven at a high speed, and the heater 5 is operated at the maximum heat output to supply hot air at high temperature and high speed. In a state where the blower fan 3 is driven, external air is sucked from the suction grill 7 at the rear end of the dryer body 1, pressurized by the blower fan 3, and then blown out from the outlet 8 at the front end of the dryer body 1. An outlet nozzle 11 according to the present invention is detachably attached to the outlet 8.

ドライヤー本体１は、図４に示すように、左右に分割された右ケース１ａと左ケース１ｂとを接合して構成してある。ドライヤー本体１の前端の吹出口８の外周面には、断面円形の筒壁からなる連結部１２が形成され、連結部１２の後側に、左右ケース１ａ・１ｂの接合状態を保持する規制リング１３が外嵌してある。吹出口８の内面の後寄りには、金属板材を打ち抜き形成した吹出グリル１４が配置してある。連結部１２の周面には、後述する内側ノズル２１を装着するための連結溝１５が周回状に形成してある。また、規制リング１３の前縁の左右には、ドライヤー本体１の後方へ向かって凹むＶ字状の回止め凹部１６が形成してある。 As shown in FIG. 4, the dryer body 1 is configured by joining a right case 1 a and a left case 1 b which are divided into left and right. A connecting portion 12 made of a cylindrical wall having a circular cross section is formed on the outer peripheral surface of the air outlet 8 at the front end of the dryer body 1, and a regulating ring that holds the joined state of the left and right cases 1 a and 1 b on the rear side of the connecting portion 12. 13 is externally fitted. On the rear side of the inner surface of the air outlet 8, there is disposed an air outlet grill 14 formed by punching a metal plate material. On the peripheral surface of the connecting portion 12, a connecting groove 15 for mounting an inner nozzle 21 described later is formed in a circular shape. Further, on the left and right sides of the front edge of the regulating ring 13, V-shaped rotation recessed portions 16 that are recessed toward the rear of the dryer body 1 are formed.

吹出ノズル１１は、先の連結部１２に装着される内側ノズル２１と、内側ノズル２１の外面に装着される外側ノズル２２とで２重筒状に構成する。図３に示すように、内側ノズル２１は、断面が円形の筒基部２３と、筒基部２３の前側のノズル開口に突設される３個の収束片２４と、筒基部２３の後に連続して設けられる連結筒２５とを一体に備えたプラスチック成形品からなる。 The blowout nozzle 11 is configured in a double cylinder shape by an inner nozzle 21 attached to the previous connecting portion 12 and an outer nozzle 22 attached to the outer surface of the inner nozzle 21. As shown in FIG. 3, the inner nozzle 21 has a cylindrical base 23 having a circular cross section, three converging pieces 24 projecting from a nozzle opening on the front side of the cylindrical base 23, and a continuous cylinder base 23. It consists of a plastic molded product integrally provided with the connecting cylinder 25 provided.

筒基部２３および収束片２４は、ノズル先端へ向かって先すぼまり状の湾曲壁で形成してあり、その最大の直径位置は、筒基部２３の後端、つまり連結筒２５との隣接部付近に位置させてある。これにより、吹出口８から内側ノズル２１の内部へ送出された乾燥風は、筒基部２３と３個の収束片２４によって絞り込まれて収束する。３個の収束片２４はそれぞれ花弁状に形成してあり、先端の山部２４ａと、隣接する山部２４ａの間に形成される谷部２４ｂとが、交互に連続し、しかも周方向へ等間隔おきに隣接する状態で形成してある。 The cylinder base 23 and the converging piece 24 are formed by a curved wall tapered toward the tip of the nozzle, and the maximum diameter position thereof is the rear end of the cylinder base 23, that is, the adjacent part to the connecting cylinder 25. It is located in the vicinity. Thereby, the dry air sent out from the blower outlet 8 to the inside of the inner nozzle 21 is narrowed down and converged by the tube base 23 and the three converging pieces 24. Each of the three converging pieces 24 is formed in a petal shape, and a crest 24a at the tip and a trough 24b formed between the adjacent crests 24a are alternately continuous and in the circumferential direction, etc. They are formed adjacent to each other at intervals.

筒基部２３の連結筒２５との隣接隅部には、外側ノズル２２を連結するための連結溝２６が周回状に形成してあり、連結筒２５の内面には先の連結溝１５と係合する連結リブ２７が周回状に形成してある。連結筒２５の後縁に連続して、左右一対の回止め片２８が後ろ向きに膨出してある。回止め片２８の外形形状は、先の回止め凹部１６の形状に一致させてある。 A connecting groove 26 for connecting the outer nozzle 22 is formed in a circular shape at a corner of the cylinder base 23 adjacent to the connecting cylinder 25, and the inner surface of the connecting cylinder 25 is engaged with the previous connecting groove 15. Connecting ribs 27 are formed in a circular shape. Continuing from the rear edge of the connecting cylinder 25, a pair of left and right turning pieces 28 bulge backward. The outer shape of the locking piece 28 is matched with the shape of the previous locking recess 16.

外側ノズル２２は、断面が円形の筒基部３１と、筒基部３１の前側のノズル開口に突設される３個の収束片３２とを一体に備えたプラスチック成形品からなる。筒基部３１の内面の３箇所には、先の連結溝２６と係合する３個の連結爪３３が等間隔おきに形成してある。 The outer nozzle 22 is formed of a plastic molded product integrally including a cylindrical base 31 having a circular cross section and three converging pieces 32 protruding from a nozzle opening on the front side of the cylindrical base 31. Three connecting claws 33 that engage with the previous connecting groove 26 are formed at equal intervals at three locations on the inner surface of the tube base 31.

内側ノズル２１と同様に、外側ノズル２２の筒基部３１および収束片３２は、ノズル先端へ向かって先すぼまり状の湾曲壁で形成してあり、その最大の直径位置は筒基部３１の後端に位置させてある。これにより、外側ノズル２２においては、３個の収束片３２のみが乾燥風を絞り込んで収束する機能を発揮する。３個の収束片３２はそれぞれ花弁状に形成してあり、先端の山部３２ａと、隣接する山部３２ａの間に形成される谷部３２ｂとが、交互に連続し、しかも周方向へ等間隔おきに隣接する状態で形成してある。収束片３２は、内側ノズル２１の収束片２４と同形で同大に形成してある。 Similar to the inner nozzle 21, the tube base 31 and the converging piece 32 of the outer nozzle 22 are formed with a curved wall tapered toward the tip of the nozzle, and the maximum diameter position is located behind the tube base 31. It is located at the end. Thereby, in the outer nozzle 22, only the three convergence pieces 32 exhibit the function which restrict | squeezes and concentrates a dry wind. Each of the three converging pieces 32 is formed in a petal shape, and a crest 32a at the tip and a trough 32b formed between adjacent crests 32a are alternately continuous, and in the circumferential direction, etc. They are formed adjacent to each other at intervals. The converging piece 32 is formed in the same shape and the same size as the converging piece 24 of the inner nozzle 21.

外側ノズル２２を内側ノズル２１に外嵌し、その連結爪３３を内側ノズル２１の連結溝２６に圧嵌係合することにより、両ノズル２１・２２を相対回転可能な状態で一体化できる。この状態の、内側ノズル２１の連結筒２５を吹出口８の周囲の連結部１２に外嵌し、回止め片２８を回止め凹部１６に係合しながら、連結リブ２７を連結溝１５に圧嵌係合することにより、吹出ノズル１１をドライヤー本体１と一体化できる。 By externally fitting the outer nozzle 22 to the inner nozzle 21 and press-fitting and engaging the connecting claw 33 with the connecting groove 26 of the inner nozzle 21, both the nozzles 21 and 22 can be integrated in a relatively rotatable state. In this state, the connecting cylinder 25 of the inner nozzle 21 is fitted around the connecting portion 12 around the air outlet 8, and the connecting rib 27 is pressed against the connecting groove 15 while the locking piece 28 is engaged with the locking recess 16. The blowing nozzle 11 can be integrated with the dryer main body 1 by fitting and engaging.

回止め片２８および回止め凹部１６は、吹出ノズル１１をドライヤー本体１に装着するときの、吹出ノズル１１の装着ガイドとして機能しており、さらに位置決め体として機能している。また、回止め凹部１６および回止め片２８は、外側ノズル２２を回転操作するときに、内側ノズル２１が連結部１２の周りに回転するのを規制する回転規制体として機能する。なお、吹出ノズル１１をドライヤー本体１から取り外す場合には、内側ノズル２１を回転操作することにより、回止め片２８を回止め凹部１６に作用する操作反力でノズル先端側へ押し出して、吹出ノズル１１の分離を容易化できる。 The rotation stopping piece 28 and the rotation stopping recess 16 function as a mounting guide for the blowing nozzle 11 when the blowing nozzle 11 is mounted on the dryer main body 1 and further function as a positioning body. Further, the rotation stopper 16 and the rotation stopper piece 28 function as a rotation restricting body that restricts the inner nozzle 21 from rotating around the connecting portion 12 when the outer nozzle 22 is rotated. When the blowout nozzle 11 is removed from the dryer main body 1, the inner nozzle 21 is rotated to push the rotation-stopping piece 28 toward the nozzle tip side by an operation reaction force acting on the rotation-stop recess 16. 11 can be easily separated.

吹出ノズル１１は、外側ノズル２２を回転操作することにより、収束姿勢と拡散姿勢とに切り換えることができる。詳しくは、図５および図７に示すように、内側ノズル２１の収束片２４と外側ノズル２２の収束片３２とが内外に重さなるように外側ノズル２２を回転操作することにより、内側ノズル２１の収束片２４のみを吹出ノズル１１のノズル開口に露出させて拡散姿勢にすることができる。この状態の外側ノズル２２の収束片３２は、内側ノズル２１の収束片２４の外面に密着している。また、外側ノズル２２の筒基部３１は、内側ノズル２１の筒基部２３の外面に常時密着している。常態において筒基部２３・３１および収束片２４・３２が密着していると、両筒基部２３・３１および両収束片２４・３２が協同して外力や衝撃力に対抗するので、その分だけ吹出ノズル１１の構造強度を向上できる。また、常態における筒基部２３・３１および収束片２４・３２が、小さな隙間を介して近接している場合にも、同様の作用を発揮できる。 The blowing nozzle 11 can be switched between a convergence posture and a diffusion posture by rotating the outer nozzle 22. Specifically, as shown in FIGS. 5 and 7, the inner nozzle 21 is rotated by rotating the outer nozzle 22 so that the converging piece 24 of the inner nozzle 21 and the converging piece 32 of the outer nozzle 22 overlap inside and outside. Only the converging piece 24 can be exposed to the nozzle opening of the blowing nozzle 11 to be in a diffusion posture. The converging piece 32 of the outer nozzle 22 in this state is in close contact with the outer surface of the converging piece 24 of the inner nozzle 21. Further, the tube base 31 of the outer nozzle 22 is always in close contact with the outer surface of the tube base 23 of the inner nozzle 21. If the cylinder bases 23 and 31 and the converging pieces 24 and 32 are in close contact with each other in the normal state, the two cylinder bases 23 and 31 and the converging pieces 24 and 32 cooperate with each other to counter external force and impact force. The structural strength of the nozzle 11 can be improved. Further, when the cylinder bases 23 and 31 and the converging pieces 24 and 32 in the normal state are close to each other through a small gap, the same action can be exhibited.

拡散姿勢においては、吹出ノズル１１に送給された乾燥風の一部が、内側ノズル２１の収束片２４の間の谷部２４ｂから漏れ出る。さらに、収束片２４の内面に沿って案内される乾燥風の一部が収束片２４の外郭線の外へ流出する。その結果、収束片２４で絞られる乾燥風の量は、吹出ノズル１１に送給された乾燥風のごく一部となり、全体として乾燥風を拡散した状態で送出できる。 In the diffusion posture, a part of the drying air supplied to the blowing nozzle 11 leaks from the trough portion 24 b between the converging pieces 24 of the inner nozzle 21. Further, a part of the drying air guided along the inner surface of the converging piece 24 flows out of the outline of the converging piece 24. As a result, the amount of the drying air squeezed by the converging piece 24 becomes a very small part of the drying air fed to the blowing nozzle 11 and can be sent out in a state where the drying air is diffused as a whole.

図１および図６に示すように、内側ノズル２１の収束片２４と外側ノズル２２の収束片３２とが周方向へ隣接するように外側ノズル２２を回転操作することにより、全ての収束片２４・３２を吹出ノズル１１のノズル開口に露出させて収束姿勢にすることができる。収束姿勢においては、内側ノズル２１の収束片２４の間の谷部２４ｂから漏れ出た乾燥風を、外側ノズル２２の収束片３２で案内して、合計６個の収束片２４・３２で乾燥風をノズル先端へ向かって絞ることができる。したがって、吹出口８から送出された乾燥風の大半を、ノズル開口の近傍まで案内し絞り込んで、風量が多くしかも指向性が強い乾燥風を髪に送給できる。 As shown in FIGS. 1 and 6, by rotating the outer nozzle 22 so that the converging piece 24 of the inner nozzle 21 and the converging piece 32 of the outer nozzle 22 are adjacent to each other in the circumferential direction, all the converging pieces 24. 32 can be exposed to the nozzle opening of the blowing nozzle 11 to achieve a convergent posture. In the converging posture, the drying air leaked from the valley portion 24b between the converging pieces 24 of the inner nozzle 21 is guided by the converging pieces 32 of the outer nozzle 22, and the total six converging pieces 24, 32 are used as the drying air. Can be squeezed toward the nozzle tip. Therefore, most of the drying air sent out from the air outlet 8 is guided and narrowed down to the vicinity of the nozzle opening, so that the drying air having a large air volume and strong directivity can be fed to the hair.

上記のように、外側ノズル２２を収束姿勢と拡散姿勢とにおいて、周方向へ遊動不能に位置保持するために、内外の両ノズル２１・２２の間に節度構造を設けている。図８に示すように、節度構造は、外側ノズル２２の筒基部３１の内面に設けた連結爪３３と、内側ノズル２１の筒基部２３の連結溝２６の周方向２個所に設けた節度凹部（節度体）３６とで構成する。節度凹部３６は、連結溝２６の前後の溝壁と、同溝を前後に横断する一対のリブ３７とで囲まれており、ひとつの連結爪３３が一方のリブ３７を乗り越えて節度凹部３６内へ落とし込み係合することにより、外側ノズル２２を位置保持できる。連結溝２６の周方向２個所に設けた節度凹部３６の中心が挟む角度は６０度である。 As described above, a moderation structure is provided between the inner and outer nozzles 21 and 22 in order to hold the outer nozzle 22 in a non-movable position in the circumferential direction in the convergence posture and the diffusion posture. As shown in FIG. 8, the moderation structure has a moderation recess (provided at two locations in the circumferential direction of the connection claw 33 provided on the inner surface of the cylinder base 31 of the outer nozzle 22 and the connection groove 26 of the cylinder base 23 of the inner nozzle 21. (Moderation body) 36. The moderation recess 36 is surrounded by a front and rear groove wall of the connection groove 26 and a pair of ribs 37 crossing the groove in the front-rear direction, and one connection claw 33 gets over one rib 37 and enters the moderation recess 36. The position of the outer nozzle 22 can be maintained by dropping and engaging. The angle between the centers of the moderation recesses 36 provided at two circumferential positions of the connecting groove 26 is 60 degrees.

上記の節度構造によれば、外側ノズル２２を一方向へ連続して回転操作する場合と、外側ノズル２２を正方向と逆方向へ交互に回転操作する場合のいずれであっても、ひとつの連結爪３３を節度凹部３６に落とし込み係合させて、外側ノズル２２を位置保持できる。 According to the moderation structure described above, one connection is possible regardless of whether the outer nozzle 22 is continuously rotated in one direction or the outer nozzle 22 is alternately rotated in the forward direction and the reverse direction. The outer nozzle 22 can be held in position by dropping the claw 33 into the moderation recess 36 and engaging with it.

上記のように構成した内側ノズル２１および外側ノズル２２に設けられる各収束片２４・３２のさらに詳細な形状、および形成位置などは以下の通りである。
内側ノズル２１の収束片２４の山部２４ａの先端位置と、外側ノズル２２の収束片３２の山部３２ａの先端位置とは、吹出ノズル１１の筒軸中心と直交する垂直平面に位置させる。このように、内外両ノズル２１・２２の収束片２４・３２の山部２４ａ・３２ａの先端位置を同一平面上に揃えると、外側ノズル２２を収束姿勢にした状態において、吹出ノズル１１内に送給された乾燥風を各収束片２４・３２で最後まで均等に絞ることができる。したがって、乱れが少ない状態の乾燥風を髪に吹き付けることができる。 More detailed shapes and formation positions of the converging pieces 24 and 32 provided on the inner nozzle 21 and the outer nozzle 22 configured as described above are as follows.
The front end position of the crest 24 a of the converging piece 24 of the inner nozzle 21 and the front end position of the crest 32 a of the converging piece 32 of the outer nozzle 22 are positioned on a vertical plane orthogonal to the center of the cylinder axis of the blowing nozzle 11. In this way, when the tip positions of the crests 24a and 32a of the converging pieces 24 and 32 of the inner and outer nozzles 21 and 22 are aligned on the same plane, the outer nozzle 22 is fed into the blowing nozzle 11 in a state of being in a converging posture. The supplied dry air can be uniformly squeezed to the end by the convergent pieces 24 and 32. Therefore, it is possible to blow dry air with little disturbance on the hair.

図１に示すように、ドライヤー本体１の吹出口８から吹出ノズル１１の先端までの距離をノズル長Ｌとするとき、内側および外側の両ノズル２１・２２の谷部２４ｂ・３２ｂの底位置を、ノズル長Ｌの略半分の位置に位置させている。このように、内外両ノズル２１・２２の収束片２４・３２の前後長さをノズル長Ｌの概ね半分に設定すると、外側ノズル２２を拡散姿勢にした場合と、収束姿勢にした場合とで、乾燥風の状態を明確に異ならせることができる。 As shown in FIG. 1, when the distance from the outlet 8 of the dryer body 1 to the tip of the outlet nozzle 11 is the nozzle length L, the bottom positions of the valleys 24b and 32b of both the inner and outer nozzles 21 and 22 are defined. The nozzle length L is approximately half of the nozzle length L. As described above, when the front and rear lengths of the converging pieces 24 and 32 of the inner and outer nozzles 21 and 22 are set to approximately half of the nozzle length L, the outer nozzle 22 is in a diffusion posture and in a convergence posture. The state of the drying air can be clearly changed.

したがって、乾燥風を広い範囲に拡散送給しながら整髪し、あるいは乾燥風を集中的に収束送給して髪の乾燥を促進するなど、使用者の使用目的に適合した状態で乾燥風を送出できる。因みに、収束片２４・３２の前後長さが、ノズル長Ｌの概ね半分に達しないほど短い場合には、乾燥風を拡散させるのが難しくなる。逆に、収束片２４・３２の前後長さが、ノズル長Ｌの概ね半分を超えて長い場合には、隣接する収束片２４・３２の間から漏れ出る乾燥風の量が多くなり、収束した後の乾燥風の風量が不足しやすい。 Therefore, the dry air is sent in a state suitable for the user's purpose, such as styling while diffusing and supplying the dry air over a wide range, or accelerating the drying of the hair by concentrating and delivering the dry air. it can. Incidentally, when the front and rear lengths of the converging pieces 24 and 32 are so short that they do not reach approximately half of the nozzle length L, it becomes difficult to diffuse the drying air. On the contrary, when the front and rear lengths of the converging pieces 24 and 32 are longer than about half of the nozzle length L, the amount of the drying air leaking from between the adjacent converging pieces 24 and 32 is increased and converged. The amount of the dry air afterwards tends to be insufficient.

内側ノズル２１および外側ノズル２２に形成される各収束片２４・３２の外形および大きさは、同形で同大に形成してある。このように、各収束片２４・３２を同形で同大に形成すると、外側ノズル２２を拡散姿勢にした場合と収束姿勢にした場合とで、各収束片２４・３２で覆われる面積の差を、１対２と大きな差にすることができる。したがって、上記と同様に、各姿勢における乾燥風の状態を明確に異ならせて、使用者の使用目的に適合した状態で乾燥風を送出できる。因みに、各収束片２４・３２の外形および大きさが、大小に異ならせてあると、外側ノズル２２を拡散姿勢にした場合と、収束姿勢にした場合とで、各収束片２４・３２で覆われる面積の差が小さくなり、拡散作用と収束作用のいずれもが中途半端なものとなる。 The converging pieces 24 and 32 formed on the inner nozzle 21 and the outer nozzle 22 have the same shape and the same size. In this way, if the converging pieces 24 and 32 are formed in the same shape and the same size, the difference in the area covered by the converging pieces 24 and 32 is different between the case where the outer nozzle 22 is in the diffusion posture and the case where the outer nozzle 22 is in the converging posture. The difference can be as great as 1: 2. Therefore, similarly to the above, the state of the dry air in each posture can be clearly changed, and the dry air can be sent out in a state suitable for the user's purpose of use. Incidentally, if the outer shapes and sizes of the respective converging pieces 24 and 32 are different from each other, they are covered by the converging pieces 24 and 32 when the outer nozzle 22 is in the diffusion posture and when it is in the converging posture. Thus, the difference in area is reduced, and both the diffusion action and the convergence action are halfway.

また、外側ノズル２２を収束状態に切り換えた場合の吹出ノズル１１の先端の開口形状が開花途中の花弁形状となるので、温風の一部を各収束片２４・３２の隣接隙間から逃がすことが可能となる。例えば、吹出ノズルの開口面が平坦である場合には、誤って頭皮の近傍にノズル開口が押し付けられるような場合に、全ての温風が頭皮や髪に吹き付けられる。しかし、上記のように、吹出ノズル１１の先端の開口形状が開花途中の花弁形状にしてあると、温風の一部を各収束片２４・３２の隣接隙間から逃がすことができるので、例えば髪が過熱されて傷むのをよく防止できる。 Further, since the opening shape at the tip of the blowing nozzle 11 when the outer nozzle 22 is switched to the converged state becomes a petal shape in the middle of flowering, a part of the warm air can escape from the adjacent gap between the converging pieces 24 and 32. It becomes possible. For example, when the opening surface of the blowing nozzle is flat, all hot air is blown to the scalp and hair when the nozzle opening is accidentally pressed near the scalp. However, as described above, if the opening shape of the tip of the blowing nozzle 11 is a petal shape in the middle of flowering, a part of the warm air can be released from the adjacent gaps of the converging pieces 24 and 32. For example, hair Can be well prevented from being damaged by overheating.

内側ノズル２１の筒基部２３および収束片２４の厚み寸法を、外側ノズル２２の筒基部３１および収束片３２の厚み寸法より小さく設定する。温風を送給する使用状態においては、内側ノズル２１は常に温風に晒されるが、外側ノズル２２は、収束姿勢にした場合に限って収束片３２が温風に晒される。その結果、温風を送給する使用状態における内側ノズル２１は、外側ノズル２２に比べて高温になる傾向がある。このような使用条件において、内側ノズル２１の筒基部２３および収束片２４の厚み寸法を小さくしておくと、内側ノズル２１の熱膨張量を小さくできる。したがって、熱膨張した内側ノズル２１の外面が、外側ノズル２２の内面を強圧するのを抑止して、長時間にわたってヘアードライヤーを使用するような場合であっても、外側ノズル２２を円滑に回転操作できる。 The thickness dimension of the cylinder base 23 and the converging piece 24 of the inner nozzle 21 is set smaller than the thickness dimension of the cylinder base 31 and the converging piece 32 of the outer nozzle 22. In the use state in which warm air is supplied, the inner nozzle 21 is always exposed to the warm air, but the outer nozzle 22 is exposed to the converging piece 32 only when it is in the converging posture. As a result, the inner nozzle 21 in a use state in which hot air is fed tends to be hotter than the outer nozzle 22. Under such usage conditions, if the thickness dimension of the cylinder base 23 and the converging piece 24 of the inner nozzle 21 is reduced, the amount of thermal expansion of the inner nozzle 21 can be reduced. Therefore, the outer surface of the inner nozzle 21 that has been thermally expanded is prevented from strongly pressing the inner surface of the outer nozzle 22, and the outer nozzle 22 is smoothly rotated even when a hair dryer is used for a long time. it can.

本発明では、内側ノズル２１と外側ノズル２２とで吹出ノズル１１を構成し、外側ノズル２２の先端に設けた収束片３２の位置を切り換えることにより、乾燥風の送出状態を収束状態と拡散状態に切り換えられるようにした。このように、吹出ノズル１１内の乾燥風に作用する収束片２４・３２の数を大小に変更して送出状態を変更すると、乾燥風を明確に絞り込み、あるいは絞り込み作用を大幅に緩和して、広い範囲にわたって拡散させることができる。したがって、乾燥風を効果的に収束し、あるいは効果的に拡散できる吹出ノズル１１が得られる。また、内側ノズル２１で回転自在に支持した外側ノズル２２を回転操作して、吹出ノズル１１を収束姿勢と拡散姿勢とに切り換えるので、従来のこの種の吹出ノズルに比べて、姿勢変更のための構造を簡素化できる。さらに、吹出ノズル１１の姿勢変更操作を誰もが簡便に行なえる。 In the present invention, the blowout nozzle 11 is constituted by the inner nozzle 21 and the outer nozzle 22, and the position of the converging piece 32 provided at the tip of the outer nozzle 22 is switched, so that the dry air sending state is made into a converging state and a diffusing state. I was able to switch. Thus, when the number of the converging pieces 24 and 32 that act on the drying air in the blowing nozzle 11 is changed to a larger or smaller size and the delivery state is changed, the drying air is clearly squeezed, or the squeezing action is greatly relaxed, It can be diffused over a wide range. Accordingly, it is possible to obtain the blowout nozzle 11 that can effectively converge or effectively diffuse the dry air. In addition, the outer nozzle 22 that is rotatably supported by the inner nozzle 21 is rotated to switch the blowing nozzle 11 between a convergence posture and a diffusion posture. Therefore, compared with the conventional blowing nozzle of this type, The structure can be simplified. Furthermore, anyone can easily perform the posture changing operation of the blowing nozzle 11.

図９ないし図１５に吹出ノズル１１の別の実施例を示す。各実施例においては、上記の実施例と異なる部分を主に説明し、同じ部材には同じ符号を付してその説明を省略する。 9 to 15 show another embodiment of the blowout nozzle 11. In each embodiment, portions different from those of the above embodiment will be mainly described, and the same members are denoted by the same reference numerals and description thereof will be omitted.

図９に示す吹出ノズル１１は、内側ノズル２１の収束片２４の前後長さを、外側ノズル２２の収束片３２の前後長さより大きくして、前者収束片２４の山部２４ａを後者収束片３２の山部３２ａよりもノズル先端側へ突出させるようにした。この吹出ノズル１１によれば、先に説明した吹出ノズル１１に比べて、３個の収束片２４の山部２４ａを通る仮想円の直径を小さくして、収束片２４による乾燥風の絞り込み作用を増強できる。 In the blowing nozzle 11 shown in FIG. 9, the length of the converging piece 24 of the inner nozzle 21 is made longer than the length of the converging piece 32 of the outer nozzle 22, and the crest 24 a of the former converging piece 24 is changed to the latter converging piece 32. It was made to protrude to the nozzle tip side from the peak portion 32a. According to this blowing nozzle 11, compared with the blowing nozzle 11 described above, the diameter of the imaginary circle passing through the peak portions 24 a of the three converging pieces 24 is reduced, and the constricting piece 24 narrows the drying air. Can be strengthened.

図１０に示す吹出ノズル１１は、内側ノズル２１を本体ケース１と一体に形成して、内側ノズル２１を本体ケース１に連結するための構造を省略し、その分だけヘアードライヤーの製造に要するコストを削減した。また、内側ノズル２１を本体ケース１と一体に形成することにより、内側ノズル２１の構造強度を向上して、落下衝撃などによる内側ノズル２１の連結部分の破損や、外側ノズル２２の円滑な回転機能が損なわれるなどを解消できる。この場合の連結爪３３は、内側ノズル２１と本体ケース１との隣接部に設けた連結溝２６に圧嵌係合する。 The blowout nozzle 11 shown in FIG. 10 eliminates the structure for connecting the inner nozzle 21 to the main body case 1 by integrally forming the inner nozzle 21 with the main body case 1, and the cost required for manufacturing the hair dryer accordingly. Reduced. In addition, by forming the inner nozzle 21 integrally with the main body case 1, the structural strength of the inner nozzle 21 is improved, the connection portion of the inner nozzle 21 is damaged due to a drop impact or the like, and the outer nozzle 22 is smoothly rotated. Can be eliminated. In this case, the connecting claw 33 is press-fitted into a connecting groove 26 provided in an adjacent portion between the inner nozzle 21 and the main body case 1.

図１１および図１２に示す吹出ノズル１１は、内側ノズル２１に設けた操作摘み４２をスライド操作して、外側ノズル２２を固定した状態で、内側ノズル２１の姿勢を収束姿勢と、拡散姿勢に変更できるようにした。そのために、外側ノズル２２の筒基部３１に操作溝４３を形成し、操作摘み４２を操作溝４３を介して外側ノズル２２の外面に露出させるようにした。また、外側ノズル２２の内面に連結リブ４０を周回状に設け、さらに回止め片４１を付加して、外側ノズル２２をドライヤー本体１の連結部１２に連結した。連結状態における回止め片４１は回止め凹部１６で受け止められる。 11 and 12, the operation knob 42 provided on the inner nozzle 21 is slid to change the posture of the inner nozzle 21 to the convergence posture and the diffusion posture with the outer nozzle 22 fixed. I was able to do it. For this purpose, an operation groove 43 is formed in the tube base 31 of the outer nozzle 22, and the operation knob 42 is exposed to the outer surface of the outer nozzle 22 through the operation groove 43. Further, the connection rib 40 is provided in a circular shape on the inner surface of the outer nozzle 22, and the rotation stopper piece 41 is further added to connect the outer nozzle 22 to the connection portion 12 of the dryer body 1. The rotation stopper piece 41 in the connected state is received by the rotation stopper recess 16.

図１３に示す吹出ノズル１１は、内側ノズル２１における収束片２４の数を４個とし、外側ノズル２２における収束片３２の数を６個とした。内側ノズル２１における収束片２４は、６個の収束片を等間隔おきに設けた場合を想定するとき、直径方向に対向する２個の収束片を省略して、４個の収束片２４を残すようにした。２個の収束片を省略した個所では、収束片２４の谷部２４ｂどうしを繋いで開口縁とするので、内側ノズル２１のノズル先端側の開口量を大きくできる。したがって、外側ノズル２２を拡散姿勢にした状態において、より多くの乾燥風を拡散することができる。なお、図１３は外側ノズル２２の収束片３２を収束姿勢にした状態を示している。 In the blowing nozzle 11 shown in FIG. 13, the number of converging pieces 24 in the inner nozzle 21 is four, and the number of converging pieces 32 in the outer nozzle 22 is six. Assuming that the six converging pieces are provided at equal intervals, the converging pieces 24 in the inner nozzle 21 omit the two converging pieces facing in the diametrical direction and leave four converging pieces 24. I did it. Where the two converging pieces are omitted, the valleys 24b of the converging pieces 24 are connected to form an opening edge, so that the opening amount on the nozzle tip side of the inner nozzle 21 can be increased. Therefore, more dry air can be diffused in a state where the outer nozzle 22 is in the diffusing posture. FIG. 13 shows a state in which the converging piece 32 of the outer nozzle 22 is in the converging posture.

図１４に示す吹出ノズル１１は、内側ノズル２１・および外側ノズル２２のそれぞれを円筒状に形成し、そのノズル先端側に収束片２４・３２を形成した。この場合の吹出ノズル１１は、先に説明した吹出ノズルに比べて、乾燥風の収束機能および拡散機能が低下する。しかし、各収束片２４・３２の前後長さが小さい分だけ乾燥風を最後まで案内できる。したがって、拡散姿勢においてもある程度の収束機能を発揮でき、収束姿勢においてはより広い範囲に乾燥風を送給できる。 In the blowout nozzle 11 shown in FIG. 14, each of the inner nozzle 21 and the outer nozzle 22 is formed in a cylindrical shape, and converging pieces 24 and 32 are formed on the nozzle tip side. The blowing nozzle 11 in this case has a drying air converging function and a diffusing function lower than the blowing nozzle described above. However, it is possible to guide the drying air to the end by the small length of the convergent pieces 24 and 32 in the longitudinal direction. Therefore, a certain degree of convergence function can be exhibited even in the diffusion posture, and the drying air can be supplied to a wider range in the convergence posture.

図１５に示す吹出ノズル１１は、内側ノズル２１および外側ノズル２２のそれぞれを、断面が楕円状の筒体で構成して、吹出ノズル１１から吹き出される乾燥風を概ね楕円状に絞るようにした。この場合の吹出ノズル１１は、外側ノズル２２を内側ノズル２１に対して着脱することにより、拡散状態と収束状態に切り換えることになる。 In the blowing nozzle 11 shown in FIG. 15, each of the inner nozzle 21 and the outer nozzle 22 is configured by a cylindrical body having an elliptical cross section so that the drying air blown from the blowing nozzle 11 is substantially elliptically narrowed. . In this case, the blowing nozzle 11 is switched between the diffusion state and the convergence state by attaching / detaching the outer nozzle 22 to / from the inner nozzle 21.

図１６および図１７は、吹出ノズルを外側ノズル（あるいは内側ノズル）のみで構成した実施例を示す。そこでは、外側ノズルのノズル開口に５個の収束片を等間隔おきに設け、収束片の谷部の底位置を、ノズル長Ｌの略半分の位置に位置させている。なお、図１６および図１７は、本発明に係るヘアードライヤーを、意匠出願の部分意匠の様式に従って作図したものであって、意匠登録を受けようとする部分は実線で表現された部分であり、意匠登録を受けようとする部分と、その他の部分との境界を一点鎖線で示している。 FIG. 16 and FIG. 17 show an embodiment in which the blowing nozzle is composed of only the outer nozzle (or inner nozzle). There, five converging pieces are provided at equal intervals in the nozzle opening of the outer nozzle, and the bottom position of the valley portion of the converging piece is located at a position approximately half the nozzle length L. 16 and 17 are drawings of the hair dryer according to the present invention according to the design of the partial design of the design application, and the part to be registered for design is a part represented by a solid line, The boundary between the part about which the design registration is to be received and the other part is indicated by a one-dot chain line.

上記の実施例では、筒基部２３・３１および収束片２４・３２を、ノズル先端へ向かって先すぼまり状の湾曲壁で形成したが、その必要はなく、筒基部２３・３１および収束片２４・３２は、全体としてノズル先端へ向かって先すぼまり状となるテーパー筒状に形成することができる。また、筒基部２３・３１はストレート円筒状に形成して、収束片２４・３２の肉壁のみを先すぼまり形状に形成することができる。 In the above-described embodiment, the cylindrical base portions 23 and 31 and the converging pieces 24 and 32 are formed by the tapered curved walls that are tapered toward the tip of the nozzle. 24 and 32 can be formed in a tapered cylindrical shape that is tapered toward the nozzle tip as a whole. Moreover, the cylinder bases 23 and 31 can be formed in a straight cylindrical shape, and only the wall surfaces of the converging pieces 24 and 32 can be formed in a tapered shape.

また、上記の実施例では、収束片２４・３２の周方向幅をノズル先端へ向かって徐々に小さくして、収束片２４・３２の展開形状を山形や花弁状などに形成したが、その必要はない。例えば、内側ノズル２１の収束片２４の展開形状を山形や花弁状として、外側ノズル２２の収束片３２の展開形状を、前後方向に等幅の四角形状に形成することができる。あるいは、収束片３２の展開形状をノズル先端へ向かって徐々に広幅とすることができる。 In the above embodiment, the circumferential width of the converging pieces 24 and 32 is gradually reduced toward the tip of the nozzle, and the developed shape of the converging pieces 24 and 32 is formed in a mountain shape or a petal shape. There is no. For example, the unfolding shape of the converging piece 24 of the inner nozzle 21 can be a mountain shape or a petal shape, and the unfolding shape of the converging piece 32 of the outer nozzle 22 can be formed in a square shape with an equal width in the front-rear direction. Alternatively, the developed shape of the converging piece 32 can be gradually widened toward the nozzle tip.

外側ノズル２２の外面に、外側ノズル２２を回転操作するための操作リングや、複数個の操作突起あるいは操作凹部を付加することができる。また、必要があれば、外側ノズル２２を収束姿勢と拡散姿勢の中間位置において節度構造で係合保持することができる。節度体３６は突起で形成することができる。さらに、連結溝２６の３箇所以上に節度体３６を設けることができる。 An operation ring for rotating the outer nozzle 22 and a plurality of operation protrusions or operation recesses can be added to the outer surface of the outer nozzle 22. Further, if necessary, the outer nozzle 22 can be engaged and held with a moderation structure at an intermediate position between the convergence posture and the diffusion posture. The moderation body 36 can be formed of a protrusion. Further, the moderating body 36 can be provided at three or more locations of the connecting groove 26.
