【０００３】
【発明が解決しようとする課題】
前記公知のものは、固定支持筒ａの上端には薄金属板からなる鍔体ｂを固定した構造である。固定支持筒ａと鍔体ｂとはかしめ付けて固定してあるが、鍔体ｂは薄金属板から形成されているので、うまくかしめ付けられず、比較的短期間でがたが生じ、誤作動の原因を作っている。
【０００４】
【発明の目的】
鍔体の確実な取付け。
【０００５】
【課題を解決するための手段】
よって、本発明は、コンロ台等の固定部１には垂直の薄金属板からなる固定支持筒２の下端を固定し、固定支持筒２の上端には固定鍔体３を固定し、該固定鍔体３は、薄金属板製の前記固定支持筒２の板厚に対して少なくとも数倍の厚みのあるものとし、前記固定支持筒２の上部には上端よりやや下方位置に膨出段部４を形成し、前記固定鍔体３の中心部には固定支持筒２の前記膨出段部４より上部が挿入される透孔５を形成し、前記透孔５の下部には、前記膨出段部４が嵌合する嵌合段部６を形成し、前記透孔５に前記固定支持筒２の前記膨出段部４より上部を挿入したのち前記透孔５から上方に突出した部分を変形７させてカシめ付けるように構成し、前記固定鍔体３の外周には薄金属板の上下摺動筒８を、前記固定鍔体３の外周面と前記上下摺動筒８の内面との摺接により案内されて上下摺動自在となるように取付け、該上下摺動筒８の上下中間位置には前記固定鍔体３の下面に衝突する薄金属板の略直角面の段部９を形成し、該段部９より下方は小径の小径部１０に形成し、前記上下摺動筒８の上端には、所定の厚さで周囲に環状溝１４を設けた集熱部１２と、センサー１６を収納した縦収納凹部１７を有する取付部１３とを有して構成した金属集熱体１１を取付け、該金属集熱体１１の前記集熱部１２の下面と前記固定鍔体３の上面との間に前記上下摺動筒８を常時上動させて前記金属集熱体１１を調理具の底面に密着させるバネ１８を装着して構成した調理具の温度検出具としたものである。
【０００６】
【実施例】
本発明の一実施例を図面により説明すると、１はコンロ台等の固定部で、固定部１には薄金属板で形成された垂直状態の固定支持筒２の下端をカシめ等任意の手段で固定し、固定支持筒２の上端には鍔体３が固定される。鍔体３は、従前のように、固定支持筒２と一体構造の板金加工で受皿状に拡大したものではなく、実施例図のように、薄金属板の固定支持筒２の板厚に対して少なくとも数倍は厚みのある鍔体３を切削加工かまたは鋳物で形成して、これを取付ける。即ち、固定支持筒２の上部の上端よりやや下方位置には、プレス加工で形成した膨出段部４を形成し、前記鍔体３の中心部には膨出段部４より上部の固定支持筒２の上端が挿入される透孔５を形成し、透孔５の下部には、前記膨出段部４が嵌合する嵌合段部６を形成し、前記透孔５に前記固定支持筒２の上端を挿入したのち、鍔体３から上方に突出した部分を変形７させてカシめ付けたものである。
【０００７】
このようにすると、従来の薄金属板からなる固定支持筒に薄金属板からなる受皿をカシめ付けた場合のような、取付がたはなくなり、固定支持筒２と鍔体３を確実に接合することができる。
前記鍔体３の外周には、薄金属板の上下摺動筒８が上下摺動自在に取付けられる。上下摺動筒８の上下中間位置には鍔体３に衝突する段部９が形成され、段部９より下方は小径の小径部１０に形成される。本実施例では、上下摺動筒８の上端は開放して開口部となり、開口部には別体の金属集熱体１１が取付けられる。金属集熱体１１は丸棒を切削加工するか鋳物で形成された相当に厚みのあるもので、集熱部１２とセンサ取付部１３とを有し、集熱部１２は糸巻きボビンのような形状で、周囲に環状溝１４を有し、集熱部１２とセンサ取付部１３は一体であり、センサ取付部１３の縦取付筒１５内にはセンサー１６の縦収納凹部１７を形し、縦収納凹部１７内にセンサー１６を収納し、接着剤で固定する。
なお、図中、１８はバネ、１９はカシメ部、２０はリード線、２１は上端開口部である。
【０００８】
【作用】
次に作用を述べる。
固定支持筒２と上下摺動筒８は、通常は、薄金属板のプレス加工の深絞り加工で形成される。固定支持筒２の下端は、コンロの固定部１にカシメ付けで固定され、固定支持筒２の上端に鍔体３がカシメ付けで固定される。
【０００９】
鍔体３の外周には上下摺動筒８が嵌合され、上下摺動筒８内にはバネ１８を収納し、上下摺動筒８の開口部２１に金属集熱体１１を取付けてカシめ１９付けする。したがって、金属集熱体１１はバネ１８の弾力で、常時上動し鍋底に密着する。
【００１０】
しかして、本願は、薄金属板の固定支持筒２の板厚に比し、少なくとも数倍は厚みのある鍔体３を切削加工または鋳物で形成して、これを取付ける。即ち、固定支持筒２の上部にはプレス加工で形成した膨出段部４を形成し、前記鍔体３の中心部には、前記固定支持筒２の上端が挿入される透孔５を形成し、透孔５の下部には、前記膨出段部４が嵌合する嵌合段部６を形成し、前記透孔５に前記固定支持筒２の上端を挿入し、嵌合段部６に前記膨出段部を嵌合させたのち、鍔体３から上方に突出した部分を変形７させてカシめ付けたものである。
【００１１】
このようにすると、従来の薄金属板からなる固定支持筒に薄金属板からなる受皿をカシめ付けた場合に生じがちの取付がたはなくなり、固定支持筒２と鍔体３を確実に接合することができる。
【００１２】
【発明の効果】
前記公知のものは、固定支持筒ａの上端には薄金属板からなる鍔体ｂを固定した構造である。固定支持筒ａと鍔体ｂとはかしめ付けて固定してあるが、鍔体ｂは薄金属板から形成されているので、うまくかしめ付けられず、比較的短期間でがたが生じ、誤作動の原因を作っている。
しかるに、本発明は、コンロ台等の固定部１には垂直の薄金属板からなる固定支持筒２の下端を固定し、固定支持筒２の上端には固定鍔体３を固定し、該固定鍔体３は、薄金属板製の前記固定支持筒２の板厚に対して少なくとも数倍の厚みのあるものとし、前記固定支持筒２の上部には上端よりやや下方位置に膨出段部４を形成し、前記固定鍔体３の中心部には固定支持筒２の前記膨出段部４より上部が挿入される透孔５を形成し、前記透孔５の下部には、前記膨出段部４が嵌合する嵌合段部６を形成し、前記透孔５に前記固定支持筒２の前記膨出段部４より上部を挿入したのち前記透孔５から上方に突出した部分を変形７させてカシめ付けるように構成し、前記固定鍔体３の外周には薄金属板の上下摺動筒８を、前記固定鍔体３の外周面と前記上下摺動筒８の内面との摺接により案内されて上下摺動自在となるように取付け、該上下摺動筒８の上下中間位置には前記固定鍔体３の下面に衝突する薄金属板の略直角面の段部９を形成し、該段部９より下方は小径の小径部１０に形成し、前記上下摺動筒８の上端には、所定の厚さで周囲に環状溝１４を設けた集熱部１２と、センサー１６を収納した縦収納凹部１７を有する取付部１３とを有して構成した金属集熱体１１を取付け、該金属集熱体１１の前記集熱部１２の下面と前記固定鍔体３の上面との間に前記上下摺動筒８を常時上動させて前記金属集熱体１１を調理具の底面に密着させるバネ１８を装着して構成した調理具の温度検出具としたものであるから、
