Description

【０００１】
【発明の属する技術分野】
本発明は加熱器に関する。
【０００２】
【従来の技術】
蒸散剤の加熱器として、蒸散剤を収容した蒸散容器をハウジングの容器格納部に格納して加熱し、蒸散剤の蒸気を外部空間へと蒸散させるものがある。
【０００３】
【発明が解決しようとする課題】
本発明の課題は、加熱器による蒸散容器の加熱効率を向上することにある。
【０００４】
また、本発明の課題は、蒸散容器における蒸散剤の残量が減少しても、加熱器による加熱効率を損なわないようにすることにある。
【０００５】
【課題を解決するための手段】
請求項１の発明は、蒸散剤を収容した蒸散容器を格納して加熱する容器格納部をハウジングに設けるに際し、容器格納部の内面を円弧状の曲面にした加熱器であって、蒸散容器は外側に凸状をなす曲面をもって蒸散剤を収容するケースと、ケースの開口を覆うガス透過性フィルムで構成され、蒸散容器のケースの曲面を、容器格納部の内面に沿わせて格納可能にするようにしたものである。
【０００６】
【発明の実施の形態】
加熱器１０は、図１に示す如く、ハウジング１１に蒸散容器３０のための容器格納部１２を備える。容器格納部１２は上部が開口しており、該開口から蒸散容器３０を出し入れする。容器格納部１２の円弧状の曲面からなる内面１２Ａは球面状の曲面或いは湾曲面とされ、該容器格納部１２の下部格納空間は、凸部１２Ｂから下方へ向かうに従い、徐々に断面積が減少するよう形成される。ハウジング１１の容器格納部１２を挟む正面にはキャップ１３が着脱可能とされ、キャップ１３に香気蒸散口１３Ａを備える。
【０００７】
加熱器１０のハウジング１１は、容器格納部１２を形成する第１ハウジング１１Ａと、第１ハウジング１１Ａの容器格納部１２を形成する側と反対側に着脱可能とされる第２ハウジング１１Ｂとからなり、第１ハウジング１１Ａと第２ハウジング１１Ｂの間にヒータ２０を内蔵している。ヒータ２０は、第２ハウジング１１Ｂに設けた支持突部１４に着座する電極端子２１と、電極端子２１のばね製突部２１Ａに背面支持されて電気的に接触されるヒータ素子２２と、ヒータ素子２２の前面に密着する状態で第１ハウジング１１Ａに密着する放熱端子２３とからなり、電極端子２１をプラグ２４に接続している。加熱器１０は、プラグ２４を壁面のコンセントに差し込んで使用するものとなる。
【０００８】
ここで、加熱器１０はヒータ２０を以下の如くに構成している。
ヒータ２０の放熱端子２３を板状とし、この放熱端子２３を第１ハウジング１１Ａの容器格納部１２の曲面状内面１２Ａに沿うように設けている。また、加熱器１０は、プラグ２４を壁面のコンセントに差し込んだ縦置き使用状態で、容器格納部１２の円弧状の曲面からなる内面１２Ａを重力の作用方向である上部から下部に沿わせて配置し、放熱端子２３の中心部を容器格納部１２の内面１２Ａの中心部（後述する突部１２Ｂ）より下部寄りにずらし、かつ放熱端子２３が上端部の側よりも下端部の側で内面１２Ａにより近づくように該放熱端子２３を鉛直面に対して傾き配置している。
【０００９】
ハウジング１１におけるヒータ２０の容器格納部１２に臨む側と反対側、換言すれば第２ハウジング１１Ｂにおける電極端子２１の着座部分の周辺に、断熱空気層２５Ａからなる断熱部２５を設け、第２ハウジング１１Ｂの外面に放熱フィンや放熱口を備えない構成とした。
【００１０】
ヒータ２０のヒータ素子２２が自己温度制御機能をもつものとした。即ち、ヒータ２０（ヒータ素子２２、放熱端子２３）が一定温度を越えると、ヒータ素子２２の抵抗が大きくなって通電を制限し、オーバーヒートを防止する。ヒータ２０は、例えば、電極端子２１をステンレス鋼、放熱端子２３をアルミにて構成し、放熱端子２３を60℃にするとき、消費電力0.4Ｗで容器格納部１２の内面１２Ａを50℃、第１ハウジング１１Ｂの外面を30℃にすることができた。従来技術では、容器格納部１２の内面１２Ａを50℃にするための消費電力は1.5Ｗであった。
【００１１】
尚、蒸散容器３０は、蒸散剤１を収容するケース３１を容器格納部１２の内面１２Ａに隙間なく又は微小隙間を介して沿う略球面３１Ａとし、その内外面を丸味を帯びたドーム状曲面とする。更に、ケース３１の内面を外側に凸形状面とし、該凸形状外側表面に凹部３１Ｂを設けることで、表面の剛性が向上し、更に変形が防止される。また、凹部３１Ｂを蒸散容器３０の表面中央部に設け、凹部３１Ｂに対応する位置の加熱器１０における容器格納部１２の内面１２Ａに凸部１２Ｂを設けることで、互いに係止し、加熱器１０を逆さまにしても、蒸散容器３０の落下を防止できる。ケース３１の開口をガス透過性の、延伸性のフィルム等のフィルム３２によって平面的にシールしている。蒸散剤１は、香料（殺虫剤等であっても良い）と溶剤とゲル化物を混合ゲル化したものを使用できる。
【００１２】
加熱器１０にあっては、ハウジング１１の容器格納部１２に蒸散容器３０を交換可能に格納して用いられ、ヒータ２０によって蒸散容器３０をケース３１の外側から加熱することにより蒸散する蒸散剤１の蒸気をフィルム３２に透過させて外部空間へと蒸散させる。このとき、蒸散剤１の蒸散につれて蒸散容器３０における蒸散剤１の剤面レベルが重力により下降していき、フィルム３０には蒸散剤１の蒸散によってケース３１の内圧が減圧するに従い、ケース３１の内側に残存する蒸散剤１に倣うように凹状に伸び変形する。
【００１３】
従って、本実施形態によれば、以下の作用がある。
（請求項１に対応する作用）
▲１▼容器格納部１２の曲面状内面１２Ａが蒸散容器３０の側面〜底面を囲む加熱面となり、蒸散容器３０への熱の集中性が良く、加熱効率を向上できる。
【００１４】
（請求項２に対応する作用）
▲２▼容器格納部１２の曲面状内面１２Ａに沿うようにヒータ２０を設けたから、ヒータ２０から容器格納部１２の曲面状内面１２Ａ（蒸散容器３０のための加熱面）への伝熱性が良く、加熱効率を向上できる。
【００１５】
（請求項３に対応する作用）
▲３▼ヒータ２０を容器格納部１２の曲面状内面１２Ａの下部寄りに設けたから、蒸散容器３０における蒸散剤１の残量が減少して蒸散剤１の剤面レベルが下降していっても、ヒータ２０の熱は容器格納部１２の曲面状内面１２Ａの下部を経て無駄なく蒸散容器３０に伝わり、加熱効率を損なわない。
【００１６】
（請求項４に対応する作用）
▲４▼蒸散容器３０が容器格納部１２の曲面状内面１２Ａに沿う丸味を帯びているから、ヒータ２０から容器格納部１２の曲面状内面１２Ａを経て蒸散容器３０に達する伝熱性を向上し、蒸散剤１の安定した蒸散を持続できる。
【００１７】
図２の加熱器１０が図１の加熱器１０と実質的に異なる点は、ハウジング１１が形成する容器格納部１２の内面１２Ａを全面的に球面状の曲面とし、かつヒータ２０の放熱端子２３も上記曲面状内面１２Ａの中心部まわりの上下左右の広い範囲に沿う球面状の曲面としたことにある。
【００１８】
【発明の効果】
以上のように本発明によれば、加熱器による蒸散容器の加熱効率を向上することができる。また、本発明によれば、蒸散容器における蒸散剤の残量が減少しても、加熱器による加熱効率を損なわないようにすることができる。

Here, the heater 10 comprises the heater 20 as follows.
The heat radiating terminal 23 of the heater 20 has a plate shape, and the heat radiating terminal 23 is provided along the curved inner surface 12A of the container housing portion 12 of the first housing 11A. In addition, the heater 10 is arranged in such a manner that the inner surface 12A formed of an arc-shaped curved surface of the container storage unit 12 is arranged from the upper part to the lower part, which is the direction of action of gravity, in the vertical use state in which the plug 24 is inserted into the wall outlet. and the inner central portion of the radiating terminals 23 shifting the center of the inner surface 12A of the container storage section 12 from the (later-described projections 12B) to the lower close, and the side of the lower end of the side of the radiating terminals 23 upper section The heat dissipating terminals 23 are inclined with respect to the vertical surface so as to be closer to the surface 12A.
