Description

【0001】
【発明の属する技術分野】
本発明は、電気採暖具の制御ケースに関するものである。
【0002】
【従来の技術】
従来の採暖具は、図5および図6に示すように、発熱体(図示せず)を内蔵した本体51と、本体51の端部に設けられ発熱体の温度を調節する制御回路52を内装した制御ケース53と、制御回路52を介して発熱体に電源を供給する電源コード54から構成されている。電源コード54には導出部55での屈曲性の向上および耐性を確保するため蛇腹構造のコードブッシュ56が設けられている(例えば、特許文献1参照)。
【0003】
【特許文献1】
特許第3044825号公報(第2頁、第2図)
【0004】
【発明が解決しようとする課題】
しかしながら、前記従来の構成では、図5に示すように電源コード54の導出部55が制御ケース53の所定位置に固定して設けられており、部屋の電源コード差込口57の位置によっては本体を部屋の角に近接して設置できないという課題があった。
【0005】
また、電源コード54には蛇腹構造のコードブッシュ56を取り付けているが、図6に示すように本体51を配置する場合、電源コード54が折り曲がり、導出部55は屈曲などに対して弱いため負荷がかかり、電源の接触不良の原因になるという課題があった。
【0006】
さらに、電源コード54とコードブッシュ56が制御ケース53から飛び出し、見映えが悪いという課題もあった。
【0007】
本発明は、前記従来の課題を解決するもので、安全でかつ見映えよく設置することができる採暖具の提供を目的とする。
【0008】
【課題を解決するための手段】
前記従来の課題を解決するために本発明は、発熱体を有する本体と、前記発熱体の温度を制御する制御回路と、前記制御回路を内装し前記本体の端部に設けた制御ケースと、前記制御回路を介して前記発熱体に給電する電源コードからなり、前記電源コードの導出部は前記制御ケースに設けられた凹形状部の底部に位置させるとともに、この底部から所定間隔をおいて位置する前記凹形状部の外部開放端側は角を丸くして、導出部から所定長さ導出された電源コードが角を丸くした凹形状部の外部開放端側に沿うようにし、さらに前記凹形状部の対向する両内壁は平行状態に、また、深さは電源コードの導出部に設けたコードブッシュがその凹形状部の内部に位置するようにそれぞれ設定したものであり、電源コードの屈曲性が向上し、電源コードの導出部にかかる負荷を軽減することができる。さらに電源コードと導出部の制御ケースからのはみ出しが少なくなるので、安全でかつ本体を見映えよく部屋に設置することができる。
【0009】
【発明の実施の形態】
本発明は、発熱体を有する本体と、前記発熱体の温度を制御する制御回路と、前記制御回路を内装し前記本体の端部に設けた制御ケースと、前記制御回路を介して前記発熱体に給電する電源コードからなり、前記電源コードの導出部は前記制御ケースに設けられた凹形状部の底部に位置させるとともに、この底部から所定間隔をおいて位置する前記凹形状部の外部開放端側は角を丸くして、導出部から所定長さ導出された電源コードが角を丸くした凹形状部の外部開放端側に沿うようにし、さらに前記凹形状部の対向する両内壁は平行状態に、また、深さは電源コードの導出部に設けたコードブッシュがその凹形状部の内部に位置するようにそれぞれ設定したものであり、電源コードの屈曲性が向上し、電源コードの導出部にかかる負荷を軽減することができる。
【0010】
また、電源コードと導出部の制御ケースからのはみ出しが少なくなるので、安全でかつ本体を見映え良く部屋に設置することができる。
【0011】
そして、前記制御ケースを上部制御ケースと下部制御ケースとにより構成し、前記下部制御ケースに電源コードを収納する溝部を設ければ、部屋の電源コード差込口の位置や方向に合わせて、電源コードを導くとともに、見映えよく電源コードを収納して本体を設置することができる。
【0012】
さらに、制御ケースを上部制御ケースと下部制御ケースとにより構成し、凹形状部の少なくとも上方開放部分を前記上部制御ケースで覆うようにすれば、制御ケースの上下からの水やホコリ等の浸入を防ぐことができ、使用時の安全性および信頼性が向上する。
【0013】
【実施例】
以下、本発明の実施例について図面を参照して説明する。
【0014】
(実施例1)
図1は面状採暖具を示し、表面材1と発熱体2と軟質発泡樹脂材3と裏面材4からなる
本体5と、発熱体2の温度を制御する制御回路6と、本体5の端部に設けられ、制御回路6を内装した上部制御ケース7と下部制御ケース8からなる制御ケース9と、制御回路6を介して発熱体2に給電する電源コード10から構成されている。
【0015】
上記構成において、上記制御ケース9の一辺部には凹形状部11が設けられ、さらに凹形状部11の外部開放端側の角は丸くなるように構成されている。
【0016】
また電源コード10の導出部12は、制御ケース9に設けた凹形状部11に位置し、導出部12にはコードブッシュ14が取り付けてある。
【0017】
また図3に示すように、下部制御ケース8には電源コード10を収納するための溝部13が設けられている。
【0018】
凹形状部11の外部開放端側の角を丸くすることにより、図2に示すように電源コード10が制御ケース9の側面を沿うように曲がるため、鋭角に曲がることなく屈曲性が良くなり、屈曲することによって電源コード10の導出部12に加わる負荷が小さくなり、信頼性が向上する。
【0019】
なお、凹形状部11の外部開放端側の角は、導出部12に屈曲力が集中しない形状であればなんでもよい。例えば、角が鈍角になっていてもよい。
【0020】
また、電源コード10の導出部12を制御ケース9に設けた凹形状部11に位置することにより、電源コード10と導出部12の制御ケース9からのはみ出しが少なくなり、見映えがよくなるとともに、設置空間を有効利用できる。
【0021】
さらに、下部制御ケース8に溝部13を設けることにより、図3に示すように電源コード10をきれいにかつ安全に収納できて見映えが良く、部屋の電源コード差込口の位置に左右されることなく、電源コード10を容易に導くことができ、部屋の角に近接して本体5を設置することが可能となる。
【0022】
(実施例2)
上記実施例1によって従来の課題は解決されたが、その一方コードブッシュ56が蛇腹構造になっているために蛇腹部分にホコリが付着しやすいという新たな課題も有していた。また、使用者が誤って制御ケース53に水等をこぼした場合に導出部55がむき出しになっているため、導出部55から制御回路52へ水が浸入し、ショートを起こす危険性もあった。
【0023】
そこで、前記問題を解決する本発明の他の実施例を示す。図1と同一構成要件については、同一符号を符し、具体的な説明は実施例1のものを援用する。
【0024】
図4に示すように、制御ケース9に設けた凹形状部11の上下両開放部分を上部制御ケース7と下部制御ケース8によって覆うようにすることで、コードブッシュ56へのホコリ等の汚れの付着を防ぐことができる。また、使用者が誤って制御ケース9の上に水等をこぼしても、導出部12から制御回路6へ水が浸入してショートする危険性が少なくなり、本体5使用時の安全性および信頼性が向上する。
【0025】
なお、上記実施例において、凹形状部11は上下両開放部分を覆うようにしたが、場合によっては上方開放部分のみを上部制御ケース7で覆うようにすることも考えられる。この場合にも上記実施例と同等の効果を得ることができる。
【0026】
【発明の効果】
以上のように、本発明によれば、安全性が高く、見映えよく設置することができる採暖具を提供することができる。
