【０００１】
【発明の属する技術分野】
本発明は、アイロン本体に電気発熱体を有さず、供給される蒸気によりアイロンかけ作業を行うオールスチームアイロンに関する。
【０００２】
【従来の技術】
従来、図６に示すように、アイロン本体41に電気発熱体を有さずに、供給される蒸気によりアイロンかけ作業を行うオールスチームアイロンにおいて、供給路43を通って供給された蒸気は、一旦、釜空室部44に充満される。そして、アイロンかけ作業時の蒸気噴出作業時にスチームバルブ45が開かれて、蒸気は、釜空室部44から吸入口46、スチームバルブ45及び主搬送路47を通って、複数の枝流路孔48へ送られ、アイロンコテ面42の蒸気噴出孔49より蒸気を噴出し、作業を行っていた。
また、釜空室部44は、作業平板50とシェル部材51とによる溶接構造で構成されている。
【０００３】
【発明が解決しようとする課題】
図６に示すように、釜空室部44、主搬送路47と枝流路孔48は、夫々圧力容器となり、その機械的強度が必要なためステンレス鋼を使用する必要があった。しかも、これらの使用板厚は大きくなり、アイロン本体41が非常に重くなるため、アイロンかけの作業性が悪くなるという問題点があった。また、ステンレスは熱伝導が悪く、コテ面42の温度が低いという欠点があった。
また、釜空室部44を構成する作業平板50とシェル部材51は、溶接構造となり、その溶接量は多く、溶接施工に手間がかかり、また、外側からの片面溶接のみにより組み立てが行われるため、圧力容器としての信頼性に不安があった。その他多くの構成部品（主搬送路47、枝流路孔48）も、溶接構造により構成・連結されているため、製作における施工性、製品に対する信頼性に問題があった。
【０００４】
そこで本発明は、簡単な構造で安全な、しかも、熱効率がよく、軽いオールスチームアイロンを提供することを目的とする。
【０００５】
【課題を解決するための手段】
上述の目的を達成するために、本発明に係るオールスチームアイロンは、アイロン本体の取付部に取り付けた蒸気供給ホースから蒸気をアイロン本体に供給して使用するオールスチームアイロンに於て、前記アイロン本体に、予熱用釜空室部分を省略して、前記取付部に形成された第１孔と連通する予熱用循環流路を形成し、前記蒸気供給ホースから該予熱用循環流路に蒸気を流して前記アイロン本体を温めるよう構成し、さらに、該アイロン本体が有する操作バルブにて前記取付部に形成された第２孔と連通遮断自在とされると共に本孔と該本孔から枝分かれする多数の枝孔とを有する枝分かれ流路をコテ面近傍に沿って配設し、該操作バルブの連通時には、前記蒸気供給ホースからの蒸気を該枝分かれ流路を介して前記コテ面に設けた多数の蒸気噴出孔より噴出させ、かつ、該操作バルブを遮断状態とした蒸気非噴出操作時には、前記第２孔から該操作バルブの上流側まで供給される蒸気を該操作バルブの上流側に設けた逆止弁を通じて前記予熱用循環流路に逃がすように構成したものである。
【０００６】
また、蒸気を蒸気供給ホースからアイロン本体に供給して使用するオールスチームアイロンに於て、アイロン本体が、平面状のコテ面に配設された多数の蒸気噴出孔と、本孔と該本孔から枝分かれする多数の枝孔とを有すると共に該コテ面に平行にかつ該蒸気噴出孔に連通するよう設けられ前記蒸気供給ホースからの蒸気をアイロン本体が有する操作バルブの操作にて該蒸気噴出孔から噴出可能とさせる枝分かれ流路と、該枝分かれ流路の上方に配設され前記蒸気供給ホースからの蒸気を流してアイロン本体を温めるための予熱用循環流路と、を備え、該枝分かれ流路の本孔と枝孔及び該予熱用循環流路を、一体物のブロック体をくり抜き成形した孔にて形成したものである
【０００７】
また、前記蒸気供給ホースは、管状の第１供給路と、該第１供給路に内挿され前記取付部から所定長さの第２供給路と、を有して２重管路構造とされ、該第１供給路は前記予熱用循環流路に連通し、該第２供給路は、前記操作バルブに連通し、該操作バルブは連通状態である蒸気噴出操作時に蒸気を前記枝分かれ流路に供給可能としたものである。
【０００８】
また、アイロン本体をアルミニウム、チタン、マグネシウム、乃至これらの合金により形成したものである。
【０００９】
【発明の実施の形態】
以下、図示の実施の形態に基づき、本発明を詳説する。
【００１０】
図１は、本発明に係るオールスチームアイロンの実施の一形態の側部断面図である。オールスチームアイロンは、図示省略の蒸気発生・供給手段（ボイラー）から、蒸気供給ホース４を介して、アイロン本体１に蒸気を供給して、その蒸気によりアイロン本体１（コテ面２）の予熱・保温をし、かつ、コテ面２から蒸気の噴出も行い、アイロンかけ作業を行うものである。
【００１１】
本発明のオールスチームアイロンは、アイロン本体１に予熱用釜空室部分を省略して、コテ面２、蒸気通過流路11、操作バルブ７等を備えたアイロン本体１を具備し、アイロン本体１の外側（上方）にプラスチック製などの火傷防止保護用のカバー９を備えている。
【００１２】
予熱用釜空室部分とは、図６に示す従来のオールスチームアイロンに設けられている拡大空間部であって、蒸気を釜空室部44に一旦に溜めて、アイロン本体41を予熱・保温し、その後、蒸気をコテ面から噴出させるための蒸気貯蔵・供給の圧力容器である。
【００１３】
蒸気通過流路11は、予熱用循環流路32と枝分かれ流路31とを備えた管路である。後で詳説するが、予熱用循環流路32は、蒸気を流して熱を伝えてアイロン本体１を温める（加熱する）ように構成したものであり、枝分かれ流路31は、枝分かれ流路31の上流端に設けた操作バルブ７の操作により供給ホース４側の管路と連通遮断自在となり、枝分かれ流路31と連通するアイロンコテ面２に設けた多数の蒸気噴出孔３…から蒸気が噴出するように構成したものである。予熱用循環流路32は、蒸気の循環流路の一部を構成するもので、ボイラーで発生した蒸気が蒸気供給ホース４を通って予熱用循環流路32を通過し、アイロン本体１から矢印Ｚ方向に蒸気が流れ出る（循環する）循環流路の一部分である。
【００１４】
操作バルブ７の開閉操作は、ハンドル14を押し込む動作等により、バルブ７の弁体７ａが弁座７ｂから離れて開状態となり、蒸気噴出状態となるもので、ハンドル14を握るのみでは、バルブ７は全閉状態を保ち、蒸気の噴出が行われない。なお、図１は、バルブを開とした蒸気噴出操作時の状態を示したものである。
【００１５】
図２にカバー９を外した状態のオールスチームアイロンの平面図を示す。図１と図２に示すように、アイロン本体１には、平坦面からなるコテ面２と、その上方にコテ面２の近傍に沿ってかつ平行な枝分かれ流路孔12…と、さらにその上方にコテ面２と平行な予熱用循環流路孔13と、を配設している。そして、コテ面２には、漸拡状の蒸気噴出口部３′を有する多数の蒸気噴出孔３…を配設し、蒸気噴出孔３…は枝分かれ流路孔12…に連通している。
【００１６】
そして、枝分かれ流路孔12…と予熱用循環流路孔13とを、一体物のブロック体から成型したものとする。即ち、鋳造や鍛造により成型されたブロック体15に、穿孔機等による、予熱用循環流路孔13（予熱用循環流路32）、及び、枝分かれ流路孔12…（枝分かれ流路31）の非貫通のくり抜き孔から成る。そのため、その孔の始端部25…は図２に示すように、溶接やプラグ栓などにより密封している。
一体物のブロック体15とは、継ぎ目のない一体ものである場合と、図示省略するが、複数ブロック体を接触・固定して一体状に組み合わせたものも含む。
【００１７】
即ち、アイロン本体１は図１に示すように、コテ面２と蒸気噴出孔３…を有する作業平板部16と、枝分かれ流路孔12…が配置する中層部17と、予熱用循環流路孔13が配置する外層部18と、操作バルブ７が配置される弁箱部19と、蒸気の供給・排出を行う受渡し配管部20と、を有する。
【００１８】
アイロン本体１の受渡し配管部20の後端部取付部29，30には、矢印Ａ方向に蒸気が供給される蒸気供給ホース４と、矢印Ｚ方向に蒸気を排出する排出バルブ21と、が取り外し可能に接続されている。排出バルブ21には、予熱用循環流路孔13により発生した水滴を除去する水滴排出バルブ22（又はスチームトラップ）を有している。
【００１９】
蒸気供給ホース４は、第１供給路５と第２供給路６とを有し、第２供給路６が第１供給路５に内挿されて２重構造の管路を形成し、第２供給路６の管路長さＬが 200mm〜500mm に設定されている。
第１供給路５は、受渡し配管部20の第１配管孔23を介して、予熱用循環流路孔13に連通しており、第２供給路６は、受渡し配管部20の第２配管孔24を介して、操作バルブ７に連通している。そして、操作バルブ７が開状態となる蒸気噴出操作時に、蒸気を枝分かれ流路孔12に供給可能となる。即ち、第２供給路６と枝分かれ流路孔12とは、操作バルブ７により連通遮蔽自在となる。
【００２０】
次に、蒸気の流れについて説明する。まず、図２に示す操作バルブ７が閉状態の蒸気非噴出時は、ボイラーからの蒸気は、第１供給路５から矢印Ｂのように、第１配管孔23を介して、後述する逆止弁８のバネ側（図４）を通過して、予熱用循環流路孔13内の矢印Ｃ及びＤ方向へ流れる。予熱用循環流路孔13は、分岐部27と合流部28とを有し、アイロン本体１内を巡行状に蒸気が通過する。分岐部27と合流部28とは一組でも副数組でもよく、アイロン本体１内を通過する蒸気により均一に温めることができるよう、全域を巡るよう配設されている。そして、予熱用循環流路孔13は最終的に一筋となり、矢印Ｅの方向に、排出バルブ21を介して水滴と共にアイロン本体１から排出され（矢印Ｚ）、ボイラー側へ帰還する。
【００２１】
また、蒸気非噴出時の、第２供給路６より送られる蒸気は、操作バルブ７が閉状態にあるため、蒸気は枝分かれ流路孔12に送られることはなく、図４に示すように、操作バルブ７の上流側（操作バルブ７の下方側部）に設けた逆止弁８が開状態となることにより、矢印Ｆのように予熱用循環流路孔13側にその蒸気を逃がしている。逆止弁８は矢印Ｆの流れ方向から順に、ボール33とそのシート面34、圧縮コイルバネ35により構成されているもので、蒸気は、操作バルブ７が閉状態の時、ボール33を押し退けて（開状態にして）容易に流過し、バネ35側に連通する予熱用循環流路孔13へ送られる。
【００２２】
これにより、第２供給路６を通って送られる蒸気は、蒸気非噴出時においても常に予熱用循環流路孔13側に逃がされ、操作バルブ７の上流側（下部）に連通する第２配管孔24に、蒸気が滞ることがなく、第２配管孔24での水滴の発生を抑えることができ、蒸気噴出操作時に切り換えても、蒸気噴出孔３（枝分かれ流路孔12）に水滴が流れないようにすることができる。
【００２３】
次に、操作バルブ７が開状態である蒸気噴出操作時は、図１と図３と図５に示すように、ボイラーからの蒸気は、第２供給路６から矢印Ｈのように、操作バルブ７を通過して、枝分かれ流路孔12内の矢印Ｉ方向へ流れる。枝分かれ流路孔12は、図３に示すように、本孔12ａと多数の枝孔12ｂ…とを有し、本孔12ａと枝孔12ｂ内に、コテ面２から多数の蒸気噴出孔３が貫設している。そして、矢印Ｊのように、蒸気が枝孔12ｂにも流れ、枝分かれ流路孔12内の蒸気は蒸気噴出孔３を通って、コテ面２から噴出される。
【００２４】
この蒸気噴出操作時においても、前で説明したように、蒸気は、第１供給路５より予熱用循環流路孔13を通ってアイロン本体１を加熱して保温し、ボイラー側へと蒸気が循環する動作を行う。
【００２５】
逆止弁８の構造・配置は、前に述べたように、蒸気非噴出操作時には、開状態となり、第２供給路６から供給された蒸気を予熱用循環流路孔13に送るよう働き、かつ、蒸気噴出操作時においては、閉状態で、予熱用循環流路孔13において発生し残留する水滴が第２供給路６側に逆流することを防止するものである。
【００２６】
また、蒸気非噴出操作時において、第２供給路６から供給された蒸気は、逆止弁８が開いて、予熱用循環流路孔13側に蒸気の流速をもって流れるため、その蒸気の流出により、逆止弁８が開いていても、予熱用循環流路孔13において発生した水滴が第２配管孔24（第２供給路６）側に逆流することがない。
【００２７】
図１に示すように、蒸気供給ホース４の第１供給路５に内挿されている第２供給路６は、所定長さＬをもって、第１供給路５内に開口して蒸気を吸入している。この所定長さＬは、予熱用循環流路孔13内で発生した水滴が第１供給路５側に逆流もしくは第１配管孔23や取付部29で発生した水滴が、枝分かれ流路孔12側に連通する第２供給路６に、浸入しないような長さを有することで、さらに蒸気噴出孔３から無駄な水滴が出ないようにしている。なお、長さＬ＜ 200mmであると、水滴が第２供給路６へ浸入しやすくなる。逆に、Ｌ＞500mm であると、第２供給路６としてのチューブが無駄となる。
【００２８】
蒸気通過流路11（枝分かれ流路孔12及び予熱用循環流路孔13）は、蒸気が流れる流路により構成されるため、蒸気は流速を有しているため、流路内において、内圧が過剰に大きくなることがない。また、孔断面は、円形とするのが好ましく、円形の管路により構成されることにより、蒸気通過流路11内の蒸気による圧力（内圧）が大きくても、蒸気通過流路11の外壁の板厚は薄くすむ。また外壁が前記のとおりブロック体15により構成されているため、アイロン本体１の発生応力は小さく、応力状態は安定しているため、その材質をアルミニウムやその合金等の軽金属とすることが可能である。また、アルミニウムは、熱伝導率がよく、予熱用循環流路孔13での蒸気による熱伝達・熱効率が極めて好ましいため、アイロンとしての特性をより発揮できるものである。また、アルミニウム以外に、チタン、マグネシウム、乃至、これらの合金によるものとしてもよい。
【００２９】
これにより、アイロン本体は薄く製作することが可能となりコンパクトな物とすることができる。従って、図１に示すように、プラスチックカバー９とアイロン本体１との間に空気の層の空間部10を有することができるため、アイロン本体１が高熱であっても、カバー９の外壁面まで熱くなることがなく、カバー９に手が触れても、火傷する心配がなく安全である。
【００３０】
【発明の効果】
本発明は上述の構成により次のような効果を奏する。
【００３１】
（請求項１によれば）大きな空洞部となる釜が無く、蒸気が小さな断面積の流路のみを通過する構成であるため、圧力流体としての蒸気を流す耐圧構造として合理的であり、構造の簡素化と軽量化が図られ、安全なオールスチームアイロンとすることができる。
【００３２】
さらに、操作バルブ７により、自由に蒸気を蒸気噴出孔３…から噴出が可能となり、また、蒸気を長時間噴出しつづけても、アイロン本体１の温度低下を防止することができる。従って、常時、非常にきれいにアイロンかけ作業が行える。
【００３３】
さらに、蒸気非噴出操作時においても、蒸気を常に予熱用循環流路 32 に送ることが可能で、蒸気を滞らせることがないため、管路内の水滴の発生を防ぎ、蒸気噴出操作時に切り換えても、蒸気噴出孔３からアイロンをかける衣服に向かって余分な水滴が噴出することがない。また、予熱用循環流路 32 内に残留する水滴が第２供給路６側に逆流することを防止するため、蒸気噴出孔３からアイロンをかける衣服に向かって余分な水滴が噴出することがない。従って、常時、非常にきれいにアイロンかけを行うことができる。
【００３４】
（請求項２によれば）蒸気の内圧による応力分布・応力状態が、均一で安定したものとすることができ、安全で、構造が簡単なオールスチームアイロンとすることができる。従って、機械的強度が若干低い材料でかつ良熱伝導性の軽金属によりアイロンが形成可能となり、非常に軽量なものとすることができ、アイロンかけの作業性が向上する。
【００３５】
（請求項３によれば）予熱用循環流路 32 内で発生し第１供給路５側に逆流もしくは第１配管孔 23 や取付部 29 で発生した水滴が、枝分かれ流路 31 側に連通する第２供給路６に、浸入しないようすることで、蒸気噴出孔３から無駄な水滴が出ないようにしている。
操作バルブ７により、自由に蒸気を蒸気噴出孔３…から噴出が可能となり、また、蒸気を長時間噴出しつづけても、アイロン本体１の温度低下を防止することができる。従って、常時、非常にきれいにアイロンかけ作業が行える。
【００３６】
（請求項４によれば）非常に軽いアイロンとすることができる。また、アイロンコテ面２の温度を上げることができ、アイロンかけの作業性が飛躍的に向上する。

The preheating circulation channel 32 constitutes a part of the steam circulation channel, and the steam generated in the boiler passes through the preheating circulation channel 32 through the steam supply hose 4, and is moved from the iron body 1 to the arrow. It is a part of a circulation channel in which steam flows out (circulates) in the Z direction.
[0014]
The opening and closing operation of the operation valve 7 is an operation in which the valve body 7a of the valve 7 is opened away from the valve seat 7b by an operation of pushing the handle 14 or the like, and the steam is ejected. Remains fully closed, and no steam is emitted. In addition, FIG. 1 shows the state at the time of the vapor | steam ejection operation which opened the valve | bulb.
[0015]
FIG. 2 shows a plan view of the all steam iron with the cover 9 removed. As shown in FIGS. 1 and 2, the iron body 1 includes a flat iron surface 2, a branched flow passage hole 12 parallel to the vicinity of the iron surface 2, and a parallel upper surface thereof. In addition, a preheating circulation passage hole 13 parallel to the iron surface 2 is disposed. The solder surface 2 is provided with a large number of steam ejection holes 3 having a gradually expanding steam ejection part 3 ′, and the steam ejection holes 3 communicate with the branched flow path holes 12.
[0016]
The branching channel holes 12 and the preheating circulation channel hole 13 are formed from a single block body. That is, the block body 15 formed by casting or forging is provided with a preheating circulation channel hole 13 (preheating circulation channel 32), a branching channel hole 12 (branching channel 31) by a punch or the like. It consists of a non-through hole. Therefore, the starting end portions 25 of the holes are sealed by welding, plug plugs or the like as shown in FIG.
The integrated block body 15 includes a case where the block body 15 is a seamless integrated body and a case where a plurality of block bodies are combined in an integrated manner by contacting and fixing, although not shown.
[0017]
That is, as shown in FIG. 1, the iron body 1 has a working flat plate portion 16 having a trowel surface 2 and steam ejection holes 3, a middle layer portion 17 in which branching passage holes 12 are arranged, and a circulation passage hole for preheating. It has an outer layer part 18 in which 13 is arranged, a valve box part 19 in which the operation valve 7 is arranged, and a delivery pipe part 20 for supplying and discharging steam.
[0018]
A steam supply hose 4 for supplying steam in the direction of arrow A and a discharge valve 21 for discharging steam in the direction of arrow Z are removed from the rear end mounting portions 29 and 30 of the delivery pipe section 20 of the iron body 1. Connected as possible. The discharge valve 21 has a water droplet discharge valve 22 (or a steam trap) that removes water droplets generated by the preheating circulation channel hole 13.
[0019]
The steam supply hose 4 has a first supply path 5 and a second supply path 6, and the second supply path 6 is inserted into the first supply path 5 to form a double-structure pipe line, The pipe length L of the supply path 6 is set to 200 mm to 500 mm.
The first supply passage 5 communicates with the preheating circulation passage hole 13 through the first piping hole 23 of the delivery piping section 20, and the second supply passage 6 is the second piping hole of the delivery piping section 20. It communicates with the operation valve 7 through 24. Then, the steam can be supplied to the branch flow path hole 12 during the steam ejection operation in which the operation valve 7 is opened. That is, the second supply channel 6 and the branch channel hole 12 can be freely shielded by the operation valve 7.
[0020]
Next, the flow of steam will be described. First, when the operation valve 7 shown in FIG. 2 is in the closed state and the steam is not ejected, the steam from the boiler, as shown by the arrow B, from the first supply path 5 through the first piping hole 23, will be described later. It passes through the spring side (FIG. 4) of the valve 8 and flows in the directions of arrows C and D in the preheating circulation passage hole 13. The preheating circulation channel hole 13 has a branch portion 27 and a junction portion 28, and the steam passes through the iron body 1 in a circular manner. The branching portion 27 and the merging portion 28 may be one set or a sub-number set, and are arranged around the entire area so that they can be uniformly heated by steam passing through the iron body 1. The preheating circulation channel hole 13 finally becomes a single line and is discharged from the iron body 1 together with water droplets through the discharge valve 21 in the direction of arrow E (arrow Z), and returns to the boiler side.
[0021]
Further, the steam sent from the second supply path 6 when the steam is not ejected is not sent to the branch channel hole 12 because the operation valve 7 is in the closed state, as shown in FIG. When the check valve 8 provided on the upstream side of the operation valve 7 (the lower side of the operation valve 7) is opened, the steam is released to the preheating circulation channel hole 13 side as indicated by an arrow F. . The check valve 8 is composed of a ball 33, its seat surface 34, and a compression coil spring 35 in order from the flow direction of the arrow F, and the steam pushes the ball 33 away when the operation valve 7 is closed ( It flows easily (in the open state) and is sent to the preheating circulation passage hole 13 communicating with the spring 35 side.
[0022]
Thereby, the steam sent through the second supply path 6 is always released to the preheating circulation passage hole 13 side even when the steam is not ejected, and communicates with the upstream side (lower part) of the operation valve 7. Steam does not stagnate in the piping hole 24 and can suppress the generation of water droplets in the second piping hole 24. Even if switching is performed at the time of steam ejection operation, water droplets remain in the steam ejection hole 3 (branch channel hole 12). It can be prevented from flowing.
[0023]
Next, during the steam ejection operation in which the operation valve 7 is in the open state, as shown in FIGS. 1, 3, and 5, the steam from the boiler is operated from the second supply path 6 as indicated by an arrow H. 7 and flows in the direction of arrow I in the branch flow path hole 12. As shown in FIG. 3, the branch channel hole 12 has a main hole 12a and a large number of branch holes 12b..., And a large number of steam ejection holes 3 are formed from the iron surface 2 in the main hole 12a and the branch holes 12b. It is penetrating. Then, as indicated by the arrow J, the steam also flows into the branch hole 12 b, and the steam in the branch flow path hole 12 is ejected from the iron surface 2 through the steam ejection hole 3.
[0024]
Even during this steam jetting operation, as described above, the steam heats the iron body 1 through the preheating circulation passage hole 13 from the first supply passage 5 and keeps the heat to the boiler side. Performs a circulating action.
[0025]
As described above, the check valve 8 has a structure / arrangement that is in an open state during the steam non-ejecting operation, and works to send the steam supplied from the second supply path 6 to the circulation path hole 13 for preheating, At the time of the steam ejection operation, water droplets that are generated and remain in the preheating circulation channel hole 13 in the closed state are prevented from flowing back to the second supply channel 6 side.
[0026]
Further, during the steam non-ejecting operation, the steam supplied from the second supply passage 6 opens at the check valve 8 and flows to the preheating circulation passage hole 13 side with a steam flow velocity. Even if the check valve 8 is open, water droplets generated in the preheating circulation passage hole 13 do not flow backward to the second piping hole 24 (second supply passage 6) side.
[0027]
As shown in FIG. 1, the second supply path 6 inserted in the first supply path 5 of the steam supply hose 4 has a predetermined length L and opens into the first supply path 5 to suck in the steam. ing. The predetermined length L is such that water droplets generated in the preheating circulation channel hole 13 flow backward to the first supply channel 5 side, or water droplets generated in the first piping hole 23 and the mounting portion 29 are separated from the branch channel hole 12 side. Since the second supply path 6 communicating with the length of the second supply path 6 has such a length that does not enter the second supply path 6, a wasteful water droplet is prevented from coming out of the steam ejection hole 3. If the length L <200 mm, water droplets can easily enter the second supply path 6. In contrast, if L> 500 mm, the tube as the second supply path 6 is wasted.
[0028]
Since the steam passage channel 11 (the branch channel hole 12 and the preheating circulation channel hole 13) is configured by a channel through which the steam flows, the steam has a flow velocity. It will not become too large. In addition, the hole cross section is preferably circular, and by being configured by a circular pipe line, even if the pressure (internal pressure) due to the steam in the steam passage channel 11 is large, the outer wall of the steam passage channel 11 The plate thickness should be thin. Further, since the outer wall is constituted by the block body 15 as described above, the generated stress of the iron body 1 is small and the stress state is stable, so that the material can be a light metal such as aluminum or an alloy thereof. is there. In addition, aluminum has a good thermal conductivity, and heat transfer and thermal efficiency by steam in the preheating circulation channel hole 13 is extremely preferable, so that it can exhibit more characteristics as an iron. In addition to aluminum, titanium, magnesium, or an alloy thereof may be used.
[0029]
As a result, the iron body can be made thin and can be made compact. Therefore, as shown in FIG. 1, since the air layer space 10 can be provided between the plastic cover 9 and the iron body 1, even if the iron body 1 is heated to the outer wall surface of the cover 9. It does not become hot, and even if the hand touches the cover 9, there is no risk of burns and it is safe.
[0030]
