The first outer heat plate 14 of this embodiment has a plurality of grooves 23 on the curved surface 14a side. The plurality of grooves 23 extend along the direction in which the first arm 11 extends. A plurality of first protrusions 15, which will be described later, are attached to the plurality of grooves 23. The plurality of groove portions 23 have a shape whose inner side is enlarged in order to prevent the plurality of first protrusions 15 from coming off. The curved surface 14a located between the plurality of grooves 23 of the first outer heat plate 14 is exposed to the outside of the first arm 11, and can curl the hair by wrapping the hair around it and heating it. That is, the first outer heat plate 14 functions as a surface member that constitutes the surface of the curling portion of the hair iron 10.
なお、本実施形態では、1つの第1外側ヒートプレート14を表面部材として機能させたが、これに限定されるものではなく、例えば、別体に形成された複数の第1外側ヒートプレートを複数の第1突出部15間に設けて表面部材として機能させてもよい。また、本実施形態では、第1アーム11の延設方向に沿って延びる複数の溝部23を第1外側ヒートプレート14に設けたが、これに限定されるものではない。例えば、第1外側ヒートプレート14に、第1アーム11の軸を中心とした周方向に沿って延びる複数の溝部を設けてもよいし、或いは、溝部を設けることなく、第1突出部15が挿通可能な複数の挿通孔を設けてもよい。

The plurality of first protrusions 15 are poor thermal conductors because they may come into direct contact with the skin (scalp, etc.) during use. Further, since the first outer heat plate 14 adjacent to the plurality of first protrusions 15 generates heat and the temperature becomes high, it is preferable to use resin with high heat resistance for the plurality of first protrusions 15. Note that the plurality of first protrusions 15 do not need to cause the user to feel heat when touching the skin during use, and for example, they may be formed entirely of a thermally poor conductor, or may be made of a core member such as metal.

Furthermore, the first inner heat plate 13 and the first outer heat plate 14 can generate heat by being thermally connected to a first film heater 16 that is supplied with electricity and generates heat. Further, the second inner heat plate 18 and the second outer heat plate 19 can generate heat by being thermally connected to a second film heater 21 that is supplied with electricity and generates heat. In this way, since the heat sources for generating heat in each of the heat plates 13, 14, 18, 19 are the film heaters 16, 21, the weight of the hair iron 10 can be reduced, unlike in the case of ceramic heaters. . In particular, when the hair iron 10 is cordless as in this embodiment, the weight of the hair iron 10 can be reduced, making it easy to carry.
また、フィルムヒータ16,21であるので、セラミックヒータである場合とは異なり、第1アーム11内及び第2アーム12内を省スペース化することができ、第1アーム11内及び第2アーム12内に内部空間24を確保することができる。これにより、本実施形態のように、第1アーム11内及び第2アーム12内に付勢部材17,22を配置することができる。
Moreover, since the film heaters 16 and 21 are used, unlike the case where ceramic heaters are used, the space inside the first arm 11 and the second arm 12 can be saved. An internal space 24 can be secured within. Thereby, the biasing members 17 and 22 can be arranged within the first arm 11 and the second arm 12 as in the present embodiment.
また、第1内側ヒートプレート13及び第1外側ヒートプレート14の双方が、同一の第1フィルムヒータ16に熱的に接続されるので、第1内側ヒートプレート13及び第1外側ヒートプレート14の双方が、それぞれに対応する個別のヒータに熱的に接続される場合とは異なり、第1アーム11内を簡易な構成にすることができる。また、第2内側ヒートプレート18及び第2外側ヒートプレート19の双方が、同一の第2フィルムヒータ21に熱的に接続されるので、上記第1アーム11側と同様に、第2アーム12内を簡易な構成にすることができる。
Moreover, since both the first inner heat plate 13 and the first outer heat plate 14 are thermally connected to the same first film heater 16, both the first inner heat plate 13 and the first outer heat plate 14 However, unlike the case where the first arm 11 is thermally connected to a corresponding individual heater, the inside of the first arm 11 can be configured simply. Further, since both the second inner heat plate 18 and the second outer heat plate 19 are thermally connected to the same second film heater 21, the second inner heat plate 18 and the second outer heat plate 19 are can be made into a simple configuration.
また、第1内側ヒートプレート13及び第1外側ヒートプレート14の双方が、第1フィルムヒータ16に接触しており、第1フィルムヒータ16によって直接的に加熱されるので、間接的に加熱する場合(他の部材を介して加熱する場合)とは異なり、第1内側ヒートプレート13及び第1外側ヒートプレート14を効率的に加熱することができる。また、同様に、第2内側ヒートプレート18及び第2外側ヒートプレート19の双方が、第2フィルムヒータ21よって直接的に加熱されるので、第2内側ヒートプレート18及び第2外側ヒートプレート19を効率的に加熱することができる。
In addition, since both the first inner heat plate 13 and the first outer heat plate 14 are in contact with the first film heater 16 and are directly heated by the first film heater 16, when heating is performed indirectly. Unlike the case of heating via other members, the first inner heat plate 13 and the first outer heat plate 14 can be efficiently heated. Similarly, since both the second inner heat plate 18 and the second outer heat plate 19 are directly heated by the second film heater 21, the second inner heat plate 18 and the second outer heat plate 19 are heated directly by the second film heater 21. It can be heated efficiently.
また、ヘアーアイロン10は、第1付勢部材17を備えており、第1内側ヒートプレート13は、第1アーム11の外部側から内部側への荷重(例えば、第2内側ヒートプレート18側からの荷重)を受けると、第1付勢部材17の付勢力に抗して第1アーム11の内部側へスライド移動する。このため、毛髪を第1内側ヒートプレート13と第2内側ヒートプレート18との間に挟んだ際に、毛髪への過大な圧力を抑えることができるので、毛髪の傷みを抑えることができる。また、本実施形態では、ヘアーアイロン10は、更に第2付勢部材22を備えているので、第2アーム12側でも毛髪への過大な圧力を抑えることができる。このため、対向方向への荷重が入力した際の内側ヒートプレートのスライド移動量を、第1アーム11側及び第2アーム12側の双方に振り分けることができる。
The hair iron 10 also includes a first biasing member 17, and the first inner heat plate 13 is configured to apply a load from the outside of the first arm 11 to the inside (for example, from the second inner heat plate 18 side). load), it slides toward the inside of the first arm 11 against the biasing force of the first biasing member 17 . Therefore, when the hair is sandwiched between the first inner heat plate 13 and the second inner heat plate 18, excessive pressure on the hair can be suppressed, so that damage to the hair can be suppressed. Furthermore, in this embodiment, the hair iron 10 further includes the second biasing member 22, so that excessive pressure on the hair can be suppressed on the second arm 12 side as well.

For example, a plurality of separately formed first outer heat plates may be used as a surface member. It may be provided between the first protrusions 47 to function as a surface member. Further, in this embodiment, the first outer heat plate 46 is provided with a plurality of grooves 55 extending along the extending direction of the first arm 41, but the present invention is not limited to this. For example, the first outer heat plate 46 may be provided with a plurality of grooves extending in the circumferential direction around the axis of the first arm 41, or the first protrusion 47 may be provided with no grooves. A plurality of insertion holes may be provided.
複数の第1突出部47は、第1アーム41の外側面うち閉状態で第2アーム42側に対向しない領域に配置されて、第1アーム41に支持され、第1アーム41の外側(第1アーム41から離間する方向)へ突出する。図16及び図18に示すように、本実施形態の複数の第1突出部47は、第1アーム41の延設方向に直交する断面において、上方(Y方向)へ、互いに略平行に突出する。本実施形態の複数の第1突出部47は、棒状に形成されて第1アーム41の外側へ突出する。複数の第1突出部47は、使用時に肌(頭皮等)に直接的に触れる可能性があるので、熱不良導体である。また、複数の第1突出部47に近接する第1外側ヒートプレート46が発熱して温度が高くなるので、複数の第1突出部47には、耐熱性の高い樹脂を使用することが好ましい。なお、複数の第1突出部47は、使用時に肌に触れた際に使用者が熱さを感じなければよく、例えば、全体を熱不良導体で形成してもよいし、或いは金属などの芯部材を熱不良導体でコーティングして形成してもよい。また、複数の第1突出部47は、第1実施形態の複数の第1突出部15と同様の構成を有しており、その同様の構成についてはその説明を省略する。
The plurality of first protrusions 47 are arranged in a region of the outer surface of the first arm 41 that does not face the second arm 42 side in the closed state, are supported by the first arm 41, and are arranged on the outer side of the first arm 41 (the 1 protrudes in the direction away from the arm 41). As shown in FIGS. 16 and 18, the plurality of first protrusions 47 of this embodiment protrude upward (in the Y direction) substantially parallel to each other in a cross section perpendicular to the extending direction of the first arm 41. . The plurality of first protrusions 47 of this embodiment are formed in a rod shape and protrude to the outside of the first arm 41. The plurality of first protrusions 47 are poor thermal conductors because they may come into direct contact with the skin (scalp, etc.) during use. Further, since the first outer heat plate 46 adjacent to the plurality of first protrusions 47 generates heat and the temperature becomes high, it is preferable to use resin with high heat resistance for the plurality of first protrusions 47. Note that the plurality of first protrusions 47 need not cause the user to feel heat when touching the skin during use, and for example, they may be formed entirely of a thermally poor conductor, or may be made of a core member such as metal. It may also be formed by coating it with a thermally poor conductor. Moreover, the plurality of first protrusions 47 have the same configuration as the plurality of first protrusions 15 of the first embodiment, and the description of the similar structure will be omitted.
図14に示すように、本実施形態の複数の第1突出部47は、側面視において、第2アーム42側の複数の第2突出部52と比較して長く形成される。すなわち、第1アーム41の複数の第1突出部47及び第2アーム42の複数の第2突出部52は、一方の突出量が他方の突出量よりも長い。このように、第1アーム41の複数の第1突出部47と第2アーム42の複数の第2突出部52との長さを異なる長さにすることによって、毛髪を巻きつけた際に、毛髪をキャッチし易く、また毛髪を巻きつけた状態から解放する際に解放し易い。
As shown in FIG. 14, the plurality of first protrusions 47 of this embodiment are formed longer than the plurality of second protrusions 52 on the second arm 42 side in side view. That is, among the plurality of first protrusions 47 of the first arm 41 and the plurality of second protrusions 52 of the second arm 42, one protrusion amount is longer than the other protrusion amount. In this way, by making the lengths of the plurality of first protrusions 47 of the first arm 41 and the plurality of second protrusions 52 of the second arm 42 different, when hair is wound, It is easy to catch hair, and it is also easy to release hair when it is released from a coiled state.
なお、本実施形態では、第1アーム41の複数の第1突出部47と第2アーム42の複数の第2突出部52との長さを異なる長さに設定したが、これに限定されるものではなく、互いに同じ長さであってもよい。また、本実施形態では、棒状の第1突出部47としたが、これに限定されるものではなく、例えば、第1突出部47は、第1アーム41の延設方向と交叉する板状に形成されて周方向に延び、第1アーム41の外側へ突出して、使用時に肌が第1外側ヒートプレート46に直接的に触れないようにするプロテクタであってもよい。
Note that in this embodiment, the plurality of first protrusions 47 of the first arm 41 and the plurality of second protrusions 52 of the second arm 42 are set to different lengths, but the present invention is not limited to this. They may have the same length. Further, in the present embodiment, the first protrusion 47 has a rod shape, but the first protrusion 47 is not limited to this. A protector may be formed and extend in the circumferential direction and protrude outward from the first arm 41 to prevent the skin from directly touching the first outer heat plate 46 during use.
図16に示すように、本実施形態の複数の第1突出部47は、第1アーム41の幅方向の内側に配置される複数の内側突出部47aと、第1アーム41の幅方向の両側の外端部に配置される複数の外側突出部47bとを有する。複数の外側突出部47bは、第1アーム41の延設方向に並んで配置される列を構成し、本実施形態では第1アーム41の幅方向の両側に1列ずつ設けられる。複数の内側突出部47aは、第1アーム41の延設方向に並んで配置される列を構成し、本実施形態では幅方向の両側の外側突出部47bの列の間に2列設けられる。なお、内側突出部47aの列の数、及び外側突出部47bの列の数は、上記に限定されるものではない。

次に、複数の突出部の変形例について説明する。上記第1実施形態~上記第3実施形態では、複数の突出部を棒状に形成したが、複数の突出部はこれに限定されるものではない。
Next, a modification of the plurality of protrusions will be described. In the first embodiment to the third embodiment, the plurality of protrusions are formed in a rod shape, but the plurality of protrusions are not limited to this.
図19は、複数の突出部の変形例を示す斜視図である。図20は、図19の第1アームから棒状の突出部及び第1外側ヒートプレートを取り外した状態を示す説明図である。
FIG. 19 is a perspective view showing a modification of the plurality of protrusions. FIG. 20 is an explanatory diagram showing a state in which the rod-shaped protrusion and the first outer heat plate are removed from the first arm of FIG. 19.
図19に示すように、ヘアーアイロン70の第1アーム71及び第2アーム72の双方に複数の突出部が設けられる。なお、複数の突出部以外の構成は、上記第1実施形態~上記第3実施形態と同様の構成であってよい。また、複数の突出部を第1アーム71及び第2アーム72のいずれか一方のみに設けてもよい。本変形例では、第1アーム71及び第2アーム72の複数の突出部は略同様の構成を有するため、以下では第1アーム71の複数の第1突出部(突出部)73について説明し、第2アーム72の複数の突出部の説明を省略する。
As shown in FIG. 19, a plurality of protrusions are provided on both the first arm 71 and the second arm 72 of the hair iron 70. Note that the configuration other than the plurality of protrusions may be the same as those in the first to third embodiments. Further, the plurality of protrusions may be provided only on either the first arm 71 or the second arm 72. In this modification, since the plurality of protrusions of the first arm 71 and the second arm 72 have substantially the same configuration, the plurality of first protrusions (protrusions) 73 of the first arm 71 will be described below, A description of the plurality of protrusions of the second arm 72 will be omitted.
複数の第1突出部73は、熱不良導体であって、第1アーム71のうち閉状態で第2アーム72に対向しない領域に配置されて、第1アーム71に支持されて外側(図19では上側)へ突出する。複数の第1突出部73は、第1アーム71の表面(外周面)に、周方向(図中のZ方向)に離間した状態で第1アーム71の延設方向(X方向)に延びる複数(図19では4つ)の列L1~L4を構成する。各列L1~L4には、複数の第1突出部73が、第1アーム71の延設方向に間隔を開けて配置される。周方向の内側の列L2,L3の複数の第1突出部73は、上記第1実施形態~上記第3実施形態と同様の棒状の突出部74である。周方向の両側の列L1,L4の複数の第1突出部73は、複数の毛状部材75aを束ねた毛ブラシ状の突出部75である。毛状部材75aは、ナイロン等で形成された人口毛であってもよいし、豚毛や猪毛等の天然毛であってもよい。すなわち、複数の第1突出部73は、複数の毛状部材75aを束ねた毛ブラシ状の突出部75を含む。各列L1~L4間には、上記第1実施形態~上記第3実施形態と同様に、第1外側ヒートプレート(表面部材)76が設けられる。なお、本変形例では、複数の第1突出部73を、毛ブラシ状の突出部75と棒状の突出部74とで構成したが、これに限定されるものではなく、複数の第1突出部73の全てを、毛ブラシ状の突出部75で構成してもよい。
The plurality of first protrusions 73 are thermally poor conductors, and are disposed in a region of the first arm 71 that does not face the second arm 72 in the closed state, and are supported by the first arm 71 and located outside (FIG. 19). Then, it protrudes upward). The plurality of first protrusions 73 are arranged on the surface (outer peripheral surface) of the first arm 71 and extend in the extending direction (X direction) of the first arm 71 while being spaced apart in the circumferential direction (Z direction in the figure). (four in FIG. 19) columns L1 to L4 are constructed. In each row L1 to L4, a plurality of first protrusions 73 are arranged at intervals in the extending direction of the first arm 71. The plurality of first protrusions 73 in the inner rows L2 and L3 in the circumferential direction are rod-shaped protrusions 74 similar to those in the first to third embodiments. The plurality of first protrusions 73 in the rows L1 and L4 on both sides in the circumferential direction are bristle brush-like protrusions 75 made by bundling a plurality of hair-like members 75a. The hair-like member 75a may be artificial hair made of nylon or the like, or may be natural hair such as pig hair or boar hair. That is, the plurality of first protrusions 73 include a bristle brush-like protrusion 75 in which a plurality of hair-like members 75a are bundled. A first outer heat plate (surface member) 76 is provided between each of the rows L1 to L4, as in the first to third embodiments. In addition, in this modification, the plurality of first protrusions 73 are composed of the bristle brush-shaped protrusions 75 and the rod-shaped protrusions 74, but the present invention is not limited to this, and the plurality of first protrusions 73 may be entirely composed of a bristle brush-like protrusion 75.
このように、複数の第1突出部73に毛ブラシ状の突出部75を含めることによって、ブラシで髪をとかしつつ、毛髪をストレート状にもカール状にも癖付けすることができる。
In this way, by including the bristle brush-like protrusions 75 in the plurality of first protrusions 73, the hair can be combed with a brush and the hair can be shaped into either a straight or curled shape.
また、複数の列L1~L4のうち、周方向の両側の列L1,L4の複数の第1突出部73を毛ブラシ状の突出部75にすることによって、髪のキャッチ力(髪を保持する力)を向上させることができる。
Further, by forming the plurality of first protrusions 73 in the rows L1 and L4 on both sides in the circumferential direction of the plurality of rows L1 to L4 into bristle brush-like protrusions 75, the hair catching force (hair holding force) is increased. power) can be improved.
また、複数の第1突出部73は、第1アーム71の外側(図19では上側)へ突出する。すなわち、複数の第1突出部73は、互いに平行に上方(所定方向の一側)へ突出する。このため、周方向の両側に毛ブラシ状の突出部75を設けても複数の第1突出部73の拡がりを抑えることができ、第1アーム71の幅方向のサイズを抑えることができる。
Furthermore, the plurality of first protrusions 73 protrude to the outside (upper side in FIG. 19) of the first arm 71. That is, the plurality of first protrusions 73 protrude upward (to one side in a predetermined direction) in parallel with each other. Therefore, even if the bristle brush-like protrusions 75 are provided on both sides in the circumferential direction, the expansion of the plurality of first protrusions 73 can be suppressed, and the size of the first arm 71 in the width direction can be suppressed.
また、図20に示すように、複数の第1突出部73のうちの毛ブラシ状の突出部75は、第1アーム71を構成する本体に、一体化されていることが好ましい。これにより、第1アーム71を構成する本体に、毛ブラシ状の突出部75を埋め込む幅を容易に確保することができる。
Further, as shown in FIG. 20, it is preferable that the bristle brush-shaped protrusion 75 of the plurality of first protrusions 73 be integrated into the main body forming the first arm 71. Thereby, it is possible to easily secure a width for embedding the bristle brush-like protrusion 75 in the main body constituting the first arm 71.
