従来から、切断した毛髪を吸引するための毛髪吸引部を備えたヘアカッターが知られている(特許文献1参照)。上記毛髪吸引部は、ヘアカッター本体内のモータでファンを回転させることでその吸引力を発生させるものであるが、次々に切断される毛髪を確実に吸引しようとすれば大きな吸引力が要求されることとなる。この要求を満たすためには、上記モータとして高出力で大型のものを内蔵させればよいのだが、この場合にはヘアカッター全体が大型化及び高重量化して使い勝手が悪くなり、また電力消費が大きくなるといった問題が生じる。
特開2002−253878号公報
Conventionally, a hair cutter including a hair suction unit for sucking cut hair has been known (see Patent Document 1). The hair suction unit generates the suction force by rotating a fan with a motor in the hair cutter body, but a large suction force is required if the hair to be cut one after another is surely sucked. The Rukoto. In order to satisfy this requirement, it is sufficient to incorporate a large motor with a high output as the above motor, but in this case, the entire hair cutter becomes larger and heavier, making it unusable and reducing power consumption. The problem of becoming larger arises.
JP 2002-253878 A

本発明は上記問題点に鑑みて発明したものであって、ファンを回転させるためのモータを大型化させることなく高い吸引力を発揮させ、小型及び省電力であっても切断した毛髪を強力に吸引することが可能なヘアカッターを提供することを課題とするものである。   The present invention has been invented in view of the above problems, and exhibits high suction power without increasing the size of a motor for rotating a fan. It is an object of the present invention to provide a hair cutter that can be sucked.

上記課題を解決するために本発明を、毛髪切断用の刃部2を先端に有するヘアカッター本体に、該刃部2にて切断した毛髪を吸引する毛髪吸引部Bを備えて成るヘアカッターにおいて、上記毛髪吸引部Bの吸引力発生手段として遠心ファン3を有するファン部27を備えるとともに、該ファン部27の下流には流路断面が下流側に向けて徐々に拡大するディフューザ部28を備え、ファン部27と、ディフューザ部28と、ファン部27内の遠心ファン3を回転駆動させるモータ5とを一体に連結させてファンブロック29を形成し、該ファンブロック29全体を、ディフューザ部28の外周縁部32aを介してヘアカッター本体のハウジング1内面に固定したものとする。 In order to solve the above-mentioned problems, the present invention provides a hair cutter comprising a hair cutter body having a blade portion 2 for cutting hair at a tip thereof and a hair suction portion B for sucking hair cut by the blade portion 2. In addition, a fan unit 27 having the centrifugal fan 3 is provided as a suction force generating means of the hair suction unit B, and a diffuser unit 28 whose flow path cross section gradually expands toward the downstream side is provided downstream of the fan unit 27. The fan unit 27, the diffuser unit 28, and the motor 5 that rotationally drives the centrifugal fan 3 in the fan unit 27 are integrally connected to form a fan block 29. The entire fan block 29 is connected to the diffuser unit 28. It is assumed that the hair cutter body is fixed to the inner surface of the housing 1 through the outer peripheral edge portion 32a.

上記構成のヘアカッターにあっては、遠心ファン3により小型で強力な吸引力を発生させるとともに、この遠心ファン3から下流側に送り出される空気はディフューザ部28にて徐々に静圧回復させてロスなく高効率で送り出されることとなる。したがって、遠心ファン3を回転させるためのモータを大型化させることなく高い吸引力を発揮させ、小型及び省電力であっても切断した毛髪を強力に吸引することが可能となる。加えて遠心ファン3の回転に伴うファンブロック29の振動発生を効果的に防止することが可能となる。 In the hair cutter having the above-described configuration, the centrifugal fan 3 generates a small and powerful suction force, and the air sent from the centrifugal fan 3 to the downstream side is gradually restored to static pressure by the diffuser portion 28 and lost. It will be sent out with high efficiency. Therefore, it is possible to exert a high suction force without increasing the size of the motor for rotating the centrifugal fan 3 and to strongly suck the cut hair even if it is small and power saving . In addition, it is possible to effectively prevent the vibration of the fan block 29 accompanying the rotation of the centrifugal fan 3.

また、上記ヘアカッターにあっては、ファン部27の遠心ファン3を囲むファンカバー26とディフューザ部28とで形成される排気流路39を、ヘアカッター本体の刃部2を有する先端側とは反対側に向けて排気を行うように形成することが好適である。このように基端側に向けて排気されるように排気流路39を設けることで、外部に吐出された排気が被散髪者に当って不快感を与えることが防止されるとともに、排気を利用してモータを冷却することが可能になる。   Moreover, in the said hair cutter, the exhaust flow path 39 formed by the fan cover 26 surrounding the centrifugal fan 3 of the fan part 27 and the diffuser part 28 is referred to as the front end side having the blade part 2 of the hair cutter body. It is preferable to form the exhaust toward the opposite side. By providing the exhaust passage 39 so as to exhaust toward the base end side in this way, the exhaust discharged to the outside is prevented from hitting the haircut person and causing discomfort, and the exhaust is used. Thus, the motor can be cooled.

また、ディフューザ部28が羽根付きディフューザであるとともに、該羽根付きディフューザの羽根数mと、遠心ファン3の羽根数nとが相違し、且つ互いに素の関係にあることも好適である。このようにすることで、遠心ファン3の回転時の風切音の発生を極力抑制することが可能となる。 It is also preferable that the diffuser portion 28 is a diffuser with blades, and the number of blades m of the diffuser with blades and the number of blades n of the centrifugal fan 3 are different and have a prime relationship . By doing in this way, it becomes possible to suppress the generation | occurrence | production of the wind noise at the time of rotation of the centrifugal fan 3 as much as possible.

更にこの場合、ディフューザ部28の外周縁部32aとヘアカッター本体のハウジング1内面との間に緩衝材を介在させることも好適である。このようにすることで振動発生を更に効果的に防止することができる。   Furthermore, in this case, it is also preferable to interpose a cushioning material between the outer peripheral edge portion 32a of the diffuser portion 28 and the inner surface of the housing 1 of the hair cutter body. By doing in this way, generation | occurrence | production of a vibration can be prevented still more effectively.

なお、以上述べた各構成は、本発明の趣旨を逸脱しない限り適宜組合せ可能である。   Each configuration described above can be appropriately combined without departing from the gist of the present invention.

本発明は、ファンを回転させるためのモータを大型化させることなく高い吸引力を発揮させ、小型及び省電力であっても切断した毛髪を強力に吸引することが可能なヘアカッターを提供することができるという効果を奏するものである。   The present invention provides a hair cutter capable of exerting a high suction force without increasing the size of a motor for rotating a fan, and capable of powerfully sucking cut hair even with a small size and power saving. It has the effect of being able to.

以下、本発明を添付図面に示す実施形態に基いて説明する。本発明の実施形態における一例のヘアカッターは図1〜図3に示す如く、片手で把持可能な細長形状を成すヘアカッター本体の外殻を成すハウジング1の長手方向一端側(以下、これを「先端側」という)に、刃部2を先端から突出させてある毛髪切断部Aを配し、長手方向の他端側(以下、これを「基端側」という)には吸引ファンである遠心ファン3を有する吸引力発生部Cを配し、各部A,C毎に各専用の駆動源となるモータ4,5を内蔵させている。両部A,Cは長手方向に所定長さの(各部A,Cの長さと同程度の)距離を隔ててハウジング1内に形成されており、毛髪切断部Aの背方から両部A,C間にかけての一連の部分には、毛髪切断部Aの刃部2先端側の外気を毛髪切断部Aの背方及び両部A,C間の隙間部分を通って吸引力発生部C内にまで吸引させる毛髪吸引部Bを形成している。   Hereinafter, the present invention will be described based on embodiments shown in the accompanying drawings. As shown in FIGS. 1 to 3, an example of the hair cutter in the embodiment of the present invention is one end in the longitudinal direction of the housing 1 that forms the outer shell of the hair cutter body that can be gripped with one hand (hereinafter referred to as “ The hair cutting part A in which the blade part 2 protrudes from the tip is arranged on the tip side), and the other end side in the longitudinal direction (hereinafter referred to as “base end side”) is a suction fan. A suction force generator C having a fan 3 is arranged, and motors 4 and 5 serving as dedicated drive sources are built in the respective parts A and C. Both parts A and C are formed in the housing 1 at a predetermined length in the longitudinal direction (similar to the length of each part A and C), and are formed in the housing 1 from the back of the hair cutting part A. In a series of parts between C, outside air at the tip of the blade part 2 of the hair cutting part A passes through the back of the hair cutting part A and the gap part between both parts A and C into the suction force generating part C. The hair suction part B to be sucked up to is formed.

なお上記の長手方向は、即ち毛髪吸引部B及び吸引力発生部Cでの吸引方向であり、したがって本文中での先端側は上流側、基端側は下流側と換言可能である。また上記の背方とは、毛髪を切断される被散髪者側から見た方向を基準とするものである。   In addition, said longitudinal direction is the suction direction in the hair suction part B and the suction force generation part C. Therefore, the front end side in this text can be rephrased as the upstream side, and the base end side can be restated as the downstream side. Moreover, said back is based on the direction seen from the haircut person side from which hair is cut.

以下、各部A〜Cの詳しい構造について説明する。まず毛髪切断部Aは、刃部2を有する刃ブロック9を先端に装着するものであり、駆動源となるモータ4と、該モータ4の出力軸4aに圧入される駆動カム7と、該駆動カム7の中心軸よりも外れた位置に取り付けられる駆動軸8とを内蔵するとともに、この駆動軸8と、刃ブロック9に備えてある案内板10とを連結させ、駆動軸8の偏心回転運動を案内板10を介して往復運動に変換させて刃部2に伝達することで、固定刃11と可動刃12とから成る刃部2の可動刃12側を固定刃11に対してヘアカッター本体の短手方向に往復摺動させる構造である。ハウジング1の側面には操作ボタン30(図2、図3等参照)を長手方向にスライド自在に露出させており、この操作ボタン30をスライド操作することでモータ4への電力供給が制御自在となっている。   Hereinafter, the detailed structure of each part AC will be described. First, the hair cutting part A is provided with a blade block 9 having a blade part 2 attached to the tip, a motor 4 serving as a drive source, a drive cam 7 press-fitted into an output shaft 4a of the motor 4, and the drive A drive shaft 8 attached to a position deviating from the center axis of the cam 7 is built in, and the drive shaft 8 is connected to a guide plate 10 provided in the blade block 9 so that the eccentric rotational motion of the drive shaft 8 is achieved. Is converted into a reciprocating motion through the guide plate 10 and transmitted to the blade portion 2, so that the movable blade 12 side of the blade portion 2 composed of the fixed blade 11 and the movable blade 12 is placed on the hair cutter body with respect to the fixed blade 11. It is a structure which reciprocates in the short direction. An operation button 30 (see FIG. 2, FIG. 3, etc.) is exposed on the side surface of the housing 1 so as to be slidable in the longitudinal direction, and the power supply to the motor 4 can be controlled by sliding the operation button 30. It has become.

次に、毛髪吸引部Bについて説明する。この毛髪吸引部Bは、毛髪切断部Aの刃部2の背方近傍に吸引口13を開口させた筒体を成すものであり、その筒体内に形成される毛髪吸引路6の基端側が吸引力発生部Cに連通する構造になっている。   Next, the hair suction part B will be described. The hair suction part B forms a cylindrical body having a suction port 13 opened in the vicinity of the back of the blade part 2 of the hair cutting part A, and the proximal end side of the hair suction path 6 formed in the cylindrical body is It is structured to communicate with the suction force generation part C.

上記筒体を成す毛髪吸引部Bは、ハウジング1外面の片面1a側である凹溝状の背面部分と、該ハウジング1外面に着脱自在に装着される半割円筒状を成す吸引ケース14の内面14aとで毛髪吸引路6を形成する構造である。ハウジング1の背面部分の短手方向両側端にはフック状の係止片15を背方に向けて一対突設してあり(図4参照)、吸引ケース14の基端側にはフック状の係止片16を基端側に向けて突設してある(図5、図6参照)。そして、ハウジング1の両端の係止片15を吸引ケース14の両側端部に係合させることで吸引ケース14をハウジング1に対して長手方向にスライド自在に係止させるとともに、吸引ケース14の基端縁をハウジング1外面の段差部17に当ててこの位置で該吸引ケース14の係止片16をハウジング1の背面部分に凹設してある被係止部18に係合させることで(図1参照)、吸引ケース14のハウジング1に対するスライドを固定し、これにより吸引ケース14をハウジング1外面に固定して毛髪吸引部Bを形成するようになっている。   The hair suction part B forming the cylindrical body has a concave groove-like back surface portion on the one surface 1a side of the outer surface of the housing 1, and an inner surface of a suction case 14 that is detachably attached to the outer surface of the housing 1. It is a structure which forms the hair suction path 6 with 14a. A pair of hook-like locking pieces 15 are provided on both side ends of the rear portion of the housing 1 so as to face the back (see FIG. 4). The locking piece 16 protrudes toward the base end side (see FIGS. 5 and 6). Then, the engaging pieces 15 at both ends of the housing 1 are engaged with both end portions of the suction case 14 so that the suction case 14 is slidably engaged with the housing 1 in the longitudinal direction. The edge is applied to the stepped portion 17 on the outer surface of the housing 1, and the locking piece 16 of the suction case 14 is engaged with the locked portion 18 recessed in the rear portion of the housing 1 at this position (see FIG. 1), the slide of the suction case 14 with respect to the housing 1 is fixed, whereby the suction case 14 is fixed to the outer surface of the housing 1 to form the hair suction portion B.

上記吸引ケース14は、吸引口13を先端に有して吸引ケース14の上流側部分を成す半割筒状の上流ブロック19と、吸引ケース14の上流ブロック19よりも下流側部分を成す半割筒状の下流ブロック20とが重なった状態で連結されることで形成されている。下流ブロック20は吸引ケース14のうち上記の如くハウジング1に固定される部分であり、上流ブロック19はこの下流ブロック20に重なりながら長手方向にスライド自在に連結され、そのスライド量に応じて吸引ケース14全体の先端側への突出量を変更する部分である。   The suction case 14 has a half-cylindrical upstream block 19 that has a suction port 13 at the tip and forms an upstream portion of the suction case 14, and a half that forms a downstream portion of the suction case 14 from the upstream block 19. It is formed by connecting with the cylindrical downstream block 20 in an overlapping state. The downstream block 20 is a portion of the suction case 14 that is fixed to the housing 1 as described above, and the upstream block 19 is connected to the downstream block 20 so as to be slidable in the longitudinal direction, and the suction case according to the sliding amount. 14 is a part for changing the amount of protrusion of the entire 14 toward the tip side.

図5(b)や図6には、上流ブロック19と下流ブロック20との連結構造を示している。下流ブロック20には、その先端側に段差部17を介して一段低い摺接面21を形成しており、上流ブロック19がこの摺接面21上に被さって段差部17と当る状態で、上流ブロック19外面と下流ブロック20外面とが面一となるように形成している。上流ブロック19内面には長手方向に伸びる断面フック状のスライド係止片22を一対だけ平行に突設してあり、上記摺接面21にはこのスライド係止片22と長手方向にスライド自在に係合する断面フック状のスライド被係止片23を二対だけ夫々平行に突設してある。   FIG. 5B and FIG. 6 show a connection structure between the upstream block 19 and the downstream block 20. The downstream block 20 is formed with a slidable contact surface 21 that is one step lower through the stepped portion 17 on the tip side, and the upstream block 19 covers the slidable contacted surface 21 and contacts the stepped portion 17 in the upstream side. The outer surface of the block 19 and the outer surface of the downstream block 20 are formed to be flush with each other. A pair of hook-like slide locking pieces 22 extending in the longitudinal direction are provided in parallel on the inner surface of the upstream block 19, and the sliding contact surface 21 is slidable in the longitudinal direction with the slide locking pieces 22. Two pairs of slide-engaged pieces 23 having hook-like cross sections to be engaged are projected in parallel.

そして上記スライド係止片22とスライド被係止片23とのスライド自在な係合により、上流ブロック19は図2に示すように先端の吸引口13が刃部2先端と同程度まで先端側に突出した突出位置と、図3に示すように先端の吸引口13が刃部2先端よりも大きく基端側に後退した後退位置との間で切換自在となっている。図6(a)中の符号24は下流ブロック20の摺動面21上に固定される弾性変形自在なクリック部材であり、また図6(b)中の符号25は上流ブロック19の内面から長手方向に所定間隔を隔てて突設される一対の凸状を成すクリック係合部であり、このクリック部材24が弾性変形しながらクリック係合部25を乗り越える際にクリック感を付与するとともに、この乗り越え時の負荷が上流ブロック19を突出位置又は後退位置に保持させる手段となっている。   As a result of the slidable engagement between the slide locking piece 22 and the slide locked piece 23, the upstream block 19 has the suction port 13 at the tip as far as the tip of the blade 2 as shown in FIG. As shown in FIG. 3, switching is possible between the protruding position and the retracted position in which the suction port 13 at the distal end is retracted larger than the distal end of the blade portion 2 toward the proximal end side. Reference numeral 24 in FIG. 6A denotes an elastically deformable click member fixed on the sliding surface 21 of the downstream block 20, and reference numeral 25 in FIG. 6B denotes a longitudinal direction from the inner surface of the upstream block 19. A click engaging portion having a pair of convex shapes projecting at a predetermined interval in the direction, and when the click member 24 gets over the click engaging portion 25 while elastically deforming, a click feeling is given. The load at the time of getting over is a means for holding the upstream block 19 in the protruding position or the retracted position.

次に、吸引力発生部Cについて図1や図7〜図9に基づいて説明する。吸引力発生部Cは、遠心ファン3をファンカバー26内に有するファン部27と、ファン部27から送り込まれる空気を減速させて静圧回復させるために流路断面を下流側に向けて徐々に拡大させて形成してあるディフューザ部28と、ファン部27内の遠心ファン3を回転駆動させるモータ5とを、この順に下流側に向けて連なるように一体に連結させて成るファンブロック29を、ハウジング1内面に固定することで形成している。ハウジング1内のファンブロック29が配される空所50と毛髪吸引部B内の毛髪吸引路6との連通部分にはフィルタ40を介在させるとともに、ハウジング1の基端部には上記空所50と連通する吐出口31を開口させており、ハウジング1の先端側外部から吸引口13を介して毛髪吸引部B内に引き込まれた空気がフィルタ40を介して空所50内のファン部27及びディフューザ部28内を通過した後に、モータ5とハウジング1内面との間の隙間を通過して吐出口31から基端側外部に放出される構造である。   Next, the suction force generator C will be described with reference to FIG. 1 and FIGS.

The motor 5 is fixed to the diffuser portion 28 with the output shaft 5a inserted through the through hole 38, and the rotational force is generated by connecting the output shaft 5a and the centrifugal fan 3 in the fan portion 27. To communicate.

なお、上記ファンブロック29において、羽根付きディフューザであるディフューザ部28の羽根数mと、遠心ファン3の羽根数nとは、両者が互いに相違する自然数であり、且つ互いに素の関係にあるように設けることが好適であり、本例ではm=7、n=9としている。遠心ファン3回転時の風切音は、遠心ファン3の羽根34が近傍の構造物(即ちディフューザ部28の羽根36)に最接近する際に大きくなるので、このように羽根数m,nを設定することで各羽根34の風切音が同時に発生することを防止し、ファンブロック29全体の静音化を図ることが可能である。 In the fan block 29, the number of blades m of the diffuser portion 28, which is a diffuser with blades, and the number of blades n of the centrifugal fan 3 are natural numbers different from each other, and are in a prime relationship with each other. In this example, m = 7 and n = 9. The wind noise when the centrifugal fan 3 rotates increases when the blades 34 of the centrifugal fan 3 are closest to the nearby structure (that is, the blades 36 of the diffuser section 28). By setting, it is possible to prevent the wind noise of each blade 34 from being generated at the same time, and to reduce the noise of the entire fan block 29.

そして、上記構成から成るファンブロック29をハウジング1内の空所50に組み込むことにより、遠心ファン3の回転で毛髪吸引部B内から引き込んだ空気を空所50内のファンブロック29を通じて基端側へと送り出して吐出口31から排気する排気流路39が形成される。上記排気流路39は、ファン部27内において遠心ファン3にて遠心方向に送り出された空気がファンカバー26に当って軸方向の基端側に向けられ、この空気がディフューザ部28内において各流路37内を軸方向の基端側に向けて流れるように形成されており、この排気流路39を通じて基端側へと送り出される空気をモータ5の外表面に当てて該モータ5を冷却するとともに、吐出口31からの排気をハウジング1の基端部から先端の刃部2と離れる方向に送り出して使用者に排気が当る煩わしさを感じさせない構造になっている。   Then, by incorporating the fan block 29 having the above structure into the space 50 in the housing 1, the air drawn from the hair suction portion B by the rotation of the centrifugal fan 3 is passed through the fan block 29 in the space 50 to the proximal end side. An exhaust passage 39 is formed to be discharged to the exhaust port 31 and exhausted from the discharge port 31. In the exhaust passage 39, the air sent out in the centrifugal direction by the centrifugal fan 3 in the fan portion 27 strikes the fan cover 26 and is directed toward the proximal end side in the axial direction. It is formed so as to flow in the flow path 37 toward the base end side in the axial direction, and air sent to the base end side through the exhaust flow path 39 is applied to the outer surface of the motor 5 to cool the motor 5. In addition, the exhaust from the discharge port 31 is sent away from the base end of the housing 1 in a direction away from the blade 2 at the tip, so that the user does not feel bothered by the exhaust.

上記構成を具備するヘアカッターには、更に図9〜図11に示すような刈り高さ調整用のアタッチメント41が着脱自在に装着される。このアタッチメント41は、ヘアカッター本体のハウジング1外面に長手方向にスライド自在に装着される半割筒状の基台42上から櫛部43を突設したものであって、上記基台42は、ハウジング1外面のうち吸引ケース14が装着される側の片面1a(即ち背面部分)とは反対側の片面1b(即ち正面部分)に装着される構造である。したがって、片面1a側での吸引ケース14の着脱及び突出量変更操作と、もう片面1b側でのアタッチメント41の着脱及びスライド操作とは、互いに干渉せず独立して行われる。   The hair cutter having the above configuration is further detachably mounted with a cutting height adjustment attachment 41 as shown in FIGS. This attachment 41 has a comb portion 43 protruding from a half-cylindrical base 42 that is slidably mounted in the longitudinal direction on the outer surface of the housing 1 of the hair cutter body. In this structure, the outer surface is mounted on one side 1b (that is, the front portion) opposite to the one side 1a (that is, the back portion) on the side where the suction case 14 is mounted. Therefore, the attachment / detachment and protrusion amount changing operation of the suction case 14 on the one side 1a side and the attachment / detachment and sliding operation of the attachment 41 on the other side 1b side are performed independently without interfering with each other.

上記アタッチメント41は、ハウジング1の片面1a側ともう片面1b側との間の両側部に長手方向に伸びるように形成される一対の凹溝44(図2、図3参照)内に、半割筒状を成す基台42の両側端部がスライド自在に嵌入することで、ハウジング1外面にスライド自在に保持されるものである。そして、ハウジング1の片面1bであってアタッチメント41に覆われる部分には、突没自在であり且つ背方のコイルばね(図示せず)により突出方向に付勢された係止ボタン45(図1参照)が設けてあって、この係止ボタン45が、アタッチメント41の内面に長手方向に所定距離を隔てて複数凹設してある係止穴(図示せず)のいずれかに嵌入することで、複数段階に設定してあるうちの任意のスライド量で保持される構造である。   The attachment 41 is divided in half into a pair of concave grooves 44 (see FIGS. 2 and 3) formed so as to extend in the longitudinal direction on both sides between the one side 1a side and the other side 1b side of the housing 1. The both ends of the cylindrical base 42 are slidably fitted to be held slidably on the outer surface of the housing 1. Then, a locking button 45 (FIG. 1) that is slidable and urged in a protruding direction by a coil spring (not shown) on the back side of the housing 1 and covered with the attachment 41. This locking button 45 is inserted into one of a plurality of locking holes (not shown) formed in the inner surface of the attachment 41 with a predetermined distance in the longitudinal direction. In this structure, the slide is held at any slide amount set in a plurality of stages.

なお、アタッチメント41の櫛部43の両側端部は、該アタッチメント41のスライド量に関わらず常に刃部2の往復動方向の両側端をカバーする形状である。即ち上記両側端部は、側面視にて刃部2が隠れる位置にまで延設されて刃部2の両側端をカバーすることで、刃部2にて切断された毛髪の飛散を防止する毛髪飛散防止壁の役割を果たすようになっている。   It should be noted that both end portions of the comb portion 43 of the attachment 41 have a shape that always covers both end portions of the blade portion 2 in the reciprocating direction regardless of the sliding amount of the attachment 41. That is, the both side end portions are extended to a position where the blade portion 2 is hidden in a side view and cover both side ends of the blade portion 2 to prevent the hair cut by the blade portion 2 from scattering. It is designed to play the role of an anti-scattering wall.

しかして、上記アタッチメント41を装着した状態のヘアカッターを用いて毛髪を切断するには、まず操作ボタン30をオフとした状態でアタッチメント41を適宜スライドさせ、所望のスライド位置にてアタッチメント41をハウジング1に保持させる。そしてハウジング1基端部に凹設してあるプラグ挿入穴47にACアダプタのプラグ(図示せず)を挿入するとともに操作ボタン30をオンとすれば、毛髪切断部Aのモータ4と吸引力発生部Cのモータ5に電力が供給されて毛髪切断部Aにあっては刃部2の可動刃12が固定刃11に対して往復摺動されるとともに、吸引力発生部Cにあっては遠心ファン3が回転駆動されて毛髪吸引部B内の空気を吸引力発生部C内に吸引して吐出口31から吐出する風力を発生させる。   In order to cut the hair using the hair cutter with the attachment 41 attached, first, the attachment 41 is appropriately slid with the operation button 30 turned off, and the attachment 41 is housed at a desired slide position. 1 to hold. When a plug (not shown) of an AC adapter is inserted into a plug insertion hole 47 provided in the base end of the housing 1 and the operation button 30 is turned on, the motor 4 of the hair cutting unit A and the suction force are generated. Electric power is supplied to the motor 5 of the part C so that the movable blade 12 of the blade part 2 is reciprocated relative to the fixed blade 11 in the hair cutting part A, and the centrifugal force is applied to the suction force generating part C. The fan 3 is rotationally driven to suck the air in the hair suction portion B into the suction force generation portion C and generate wind force discharged from the discharge port 31.

ここで、アタッチメント41の櫛部43背面側を被散髪者の頭部に当てながらヘアカッター本体を移動させていくと、刃部2により毛髪が順次切断されていくとともに、切断された毛髪は刃部2と近接した位置で開口する吸引口13から外気と共に毛髪吸引部Bの毛髪吸引路6内に吸引され、吸入された外気はフィルタ40を通じて吸引力発生部C内に吸引されるとともに、吸引された毛髪は毛髪吸引路6内に順次貯め置かれていく。吸引力発生部C内に吸入された空気は既述の如くファン部27及びディフューザ部28内を通過した後にモータ5とハウジング1との間を通過し、基端部の吐出口31から外部に吐出される。   Here, when the hair cutter body is moved while the back side of the comb portion 43 of the attachment 41 is applied to the head of the haircut person, the hair is sequentially cut by the blade portion 2, and the cut hair is the blade portion. 2 is sucked into the hair suction passage 6 of the hair suction section B together with outside air from the suction port 13 opened at a position close to 2, and the sucked outside air is sucked into the suction force generating section C through the filter 40 and sucked. The hair is sequentially stored in the hair suction path 6. The air sucked into the suction force generating part C passes between the motor part 5 and the housing 1 after passing through the fan part 27 and the diffuser part 28 as described above, and is discharged from the outlet 31 at the base end part to the outside. Discharged.

ここで、本例にあっては毛髪吸引部Bでの吸引力発生手段として、吸引力発生部C内に遠心ファン3を備えてあるので、小型であっても強い吸引力が得られるとともに、更にこの遠心ファン3から下流側に送り出される空気をディフューザ部28にて徐々に静圧回復させてロスなく高効率で送り出すことが可能になっている。したがって本例のヘアカッターはモータ5を大型化させることなく高い吸引力を発揮させることが可能であり、小型であっても切断した毛髪を強力に吸引することが可能なヘアカッターとなっている。   Here, in this example, since the centrifugal fan 3 is provided in the suction force generation part C as the suction force generation means in the hair suction part B, a strong suction force can be obtained even in a small size, Further, the air sent from the centrifugal fan 3 to the downstream side can be gradually recovered by static pressure at the diffuser portion 28 and sent out with high efficiency without loss. Therefore, the hair cutter of this example can exhibit a high suction force without increasing the size of the motor 5, and is a hair cutter capable of powerfully sucking cut hair even if it is small. .

刈り高さを変更する場合にはアタッチメント41を長手方向にスライドさせればよく、また吸引口13の突出量を変更する場合には吸引ケース14の上流ブロック19を長手方向にスライドさせればよい。アタッチメント41と吸引ケース14とは、ハウジング1の毛髪切断部Aが配される先端側外面の片面1a側ともう片面1b側に夫々独立した状態で支持させる構造なので、両者41,14の着脱操作やスライド操作は互いに影響を受けないようになっている。   The attachment 41 may be slid in the longitudinal direction when changing the cutting height, and the upstream block 19 of the suction case 14 may be slid in the longitudinal direction when changing the protruding amount of the suction port 13. . The attachment 41 and the suction case 14 are structured to be supported independently on one side 1a side and the other side 1b side of the outer surface on the front end side where the hair cutting part A of the housing 1 is arranged. And slide operations are not affected by each other.

ここで、上記アタッチメント41の代わりに図12に示すような別形態のアタッチメント41′を用いても構わない。このアタッチメント41′はハウジング1の先端部にスライド不能に係止される構造であり、櫛部43′の高さが相違する複数種類のアタッチメント41′を用意して適宜交換することで、刈り高さが調整可能となっている。   Here, instead of the attachment 41, another form of attachment 41 'as shown in FIG. 12 may be used. The attachment 41 'is structured to be slidably locked to the front end portion of the housing 1, and a plurality of types of attachments 41' having different heights of the comb portion 43 'are prepared and appropriately replaced to obtain a cutting height. Is adjustable.

散髪終了後は、操作ボタン30をオフにして刃部2の往復駆動及び遠心ファン3の回転駆動を停止させ、吸引ケース14をハウジング1から取り外して毛髪吸引部B内に貯まった毛髪を廃棄すればよい。ここで、本例にあっては吸引ケース14の取り外しにより、毛髪吸引部B内の吸引口13から遠心ファン3近傍(フィルタ40直前)に至るまでの全部分を開放させて、毛髪吸引路6内に貯まった毛髪を効率良く且つ確実に廃棄することが可能である。   After the haircut is finished, the operation button 30 is turned off to stop the reciprocating drive of the blade part 2 and the rotational drive of the centrifugal fan 3, and the suction case 14 is removed from the housing 1 and the hair accumulated in the hair suction part B is discarded. That's fine. Here, in this example, by removing the suction case 14, the entire portion from the suction port 13 in the hair suction part B to the vicinity of the centrifugal fan 3 (immediately before the filter 40) is opened, and the hair suction path 6 is opened. It is possible to efficiently and reliably discard the hair stored inside.

なお、例えば耳の周りを散髪する際にはアタッチメント41を装着せずに用いるが、このときには吸引ケース14の吸引口13周辺が被散髪者の頭部に接触して邪魔になるので、上流ブロック19を後退させておく。このように使用部位にあわせて吸引口13の突出量を変更可能であるから、使用者にとっては使い勝手がよいものである。   For example, when hair is cut around the ear, the attachment 41 is used without being attached. At this time, the area around the suction port 13 of the suction case 14 comes into contact with the head of the haircut person and becomes an obstacle. 19 is retracted. Thus, the amount of protrusion of the suction port 13 can be changed in accordance with the use site, which is convenient for the user.
