本発明の一実施例をコンロＫのバーナＢの例にて図面により説明すると、１はコンロＫのバーナＢ等に使用する炊事具２の温度を検出する温度検出装置であり、前記バーナＢに設ける。
前記コンロＫおよびバーナＢは、周知であるので、詳細な図は省略して一例を示すと、少なくとも、コンロＫは１台または横方向に並ぶ２台のバーナＢを有し（図示省略）、バーナＢは混合管３の先端に環状のバーナーベース４を連結する。バーナーベース４の上部には環状のバーナキャップ５を着脱自在に載置する。バーナーベース４およびバーナキャップ５の略中心には上下に貫通するように挿入孔６を設ける。 An embodiment of the present invention will be described with reference to an example of a burner B of a stove K. Reference numeral 1 denotes a temperature detection device that detects the temperature of a cooking utensil 2 used for a burner B of a stove K, etc. Provide.
Since the stove K and the burner B are well known, a detailed diagram is omitted, and an example is shown. At least, the stove K has one or two burners B arranged in the horizontal direction (not shown), The burner B connects an annular burner base 4 to the tip of the mixing tube 3. An annular burner cap 5 is detachably mounted on the burner base 4. An insertion hole 6 is provided at substantially the center of the burner base 4 and the burner cap 5 so as to penetrate vertically.

バーナキャップ５の周縁には溝を形成し、バーナキャップ５をバーナーベース４に載置すると、バーナーベース４とバーナキャップ５との間に外方に向けて炎を形成する複数の炎口７が周方向に沿って間隔を隔てて形成される。
前記バーナキャップ５は、コンロＫのトッププレート１０に形成したバーナ用開口部１１内の略中心に位置するように設け、前記バーナ用開口部１１には、該バーナ用開口部１１の周縁に環状の汁受け皿１２の周縁を載置させて設ける。また、前記汁受け皿１２またはバーナ用開口部１１の周辺のトッププレート１０には前記炊事具２を載置する五徳１３を設ける。 A groove is formed in the peripheral edge of the burner cap 5, and when the burner cap 5 is placed on the burner base 4, a plurality of flame openings 7 that form flames outwardly are formed between the burner base 4 and the burner cap 5. Formed at intervals along the circumferential direction.
The burner cap 5 is provided so as to be positioned substantially at the center in the burner opening 11 formed in the top plate 10 of the stove K, and the burner opening 11 has an annular shape around the periphery of the burner opening 11. The peripheral edge of the soup saucer 12 is placed and provided. Further, the top plate 10 in the vicinity of the soup pan 12 or the burner opening 11 is provided with five victories 13 on which the cooking utensil 2 is placed.

しかして、前記コンロＫには、前記五徳１３に載置した炊事具２の底面に当接するように温度検出装置１の当接体１５を設ける。当接体１５は移動側支持パイプ１６の上部に設け、移動側支持パイプ１６の下部はコンロＫの任意の固定部に対して前記バーナＢの挿入孔６内を上下動するように構成する。前記当接体１５内に炊事具２の温度を検出するサーミスター１７を設ける。
当接体１５は、銅等の熱伝導率の高い部材により形成し、その上部を大径にした鍔部１８に形成し、鍔部１８に続いて所定の厚さを有する筒部１９を形成する。該筒部１９内には下側から前記サーミスター１７を収納する。前記鍔部１８を除く当接体１５の筒部１９の外周には筒状の断熱部材２０を設ける。断熱部材２０はフッ素樹脂等の熱伝導率の低い部材により形成する。断熱部材２０は、前記筒部１９より長く形成し、筒部１９より下方に伸びるサーミスター１７のリード線２１の上部部分を耐熱性の樹脂２２により固定する。 Accordingly, the stove K is provided with the contact body 15 of the temperature detection device 1 so as to contact the bottom surface of the cooking utensil 2 placed on the virtues 13. The contact body 15 is provided at the upper part of the moving side support pipe 16, and the lower part of the moving side support pipe 16 is configured to move up and down in the insertion hole 6 of the burner B with respect to an arbitrary fixing part of the stove K. A thermistor 17 for detecting the temperature of the cooker 2 is provided in the contact body 15.
The contact body 15 is formed of a member having high thermal conductivity such as copper, and the upper portion thereof is formed on the flange portion 18 having a large diameter, and the tube portion 19 having a predetermined thickness is formed following the flange portion 18. To do. The thermistor 17 is housed in the cylindrical portion 19 from below. A cylindrical heat insulating member 20 is provided on the outer periphery of the cylindrical portion 19 of the contact body 15 excluding the flange portion 18. The heat insulating member 20 is formed of a member having a low thermal conductivity such as a fluororesin. The heat insulating member 20 is formed longer than the cylindrical portion 19, and an upper portion of the lead wire 21 of the thermistor 17 extending downward from the cylindrical portion 19 is fixed by a heat resistant resin 22.

前記筒部１９の下部外周には側方に突き出る抜け止め係合部２３を形成し、抜け止め係合部２３は前記断熱部材２０の内面に形成した係合凹部２４に係合させる。
前記断熱部材２０は、前記移動側支持パイプ１６の上部の筒状のサーミスター取付部２５に固定する。サーミスター取付部２５は、移動側支持パイプ１６および断熱部材２０よりやや大径に形成し、サーミスター取付部２５に断熱部材２０を嵌合させて任意の方法で固定する。
したがって、当接体１５は移動側支持パイプ１６とは直接接触せず、当接体１５の周囲と移動側支持パイプ１６のサーミスター取付部２５との間には断熱部材２０が介在することになり、当接体１５から移動側支持パイプ１６への熱伝導を遮断あるいは抑制し、勿論、移動側支持パイプ１６から当接体１５への熱伝導も遮断あるいは抑制する。 A retaining engagement portion 23 protruding laterally is formed on the outer periphery of the lower portion of the cylindrical portion 19, and the retaining engagement portion 23 is engaged with an engagement recess 24 formed on the inner surface of the heat insulating member 20.
The heat insulating member 20 is fixed to a cylindrical thermistor mounting portion 25 at the top of the moving side support pipe 16. The thermistor mounting part 25 is formed to have a slightly larger diameter than the moving support pipe 16 and the heat insulating member 20, and the heat insulating member 20 is fitted to the thermistor mounting part 25 and fixed by an arbitrary method.
Therefore, the contact body 15 is not in direct contact with the movable support pipe 16, and the heat insulating member 20 is interposed between the periphery of the contact body 15 and the thermistor mounting portion 25 of the movable support pipe 16. Thus, heat conduction from the contact body 15 to the moving support pipe 16 is interrupted or suppressed, and of course, heat transfer from the moving support pipe 16 to the contact body 15 is also blocked or suppressed.

この場合、当接体１５とサーミスター１７と断熱部材２０はサーミスター取付部２５と一体状に形成し、サーミスター取付部２５は、所定の大きさの前記サーミスター１７と所定の厚さの断熱部材２０とを収納しうる大きさ（直径）で、かつ、炊事具２の底面に密着当接する範囲で、可及的に小さく（小径）形成する。
即ち、従来の温度検出装置１のように当接体１５およびサーミスター１７を移動側支持パイプ１６に対して上下させる上下動機構Ｄを、サーミスター１７の取付部２５付近に設けると、必然的に大径となるが、本願では、サーミスター１７および断熱部材２０の容積を基準に、これらが収納できる大きさに、サーミスター取付部２５を形成しているので、前記コンロＫの小径のバーナキャップ５への装着を可能にしている。 In this case, the contact body 15, the thermistor 17, and the heat insulating member 20 are integrally formed with the thermistor mounting portion 25, and the thermistor mounting portion 25 has a predetermined size with the thermistor 17 having a predetermined thickness. The heat insulating member 20 is formed in a size (diameter) that can accommodate the heat insulating member 20 and is formed as small as possible (small diameter) as long as it is in close contact with the bottom surface of the cooking utensil 2.
That is, it is inevitable that a vertical movement mechanism D for moving the contact body 15 and the thermistor 17 up and down with respect to the moving support pipe 16 as in the conventional temperature detecting device 1 is provided in the vicinity of the mounting portion 25 of the thermistor 17. However, in the present application, the thermistor mounting portion 25 is formed in such a size that the thermistor 17 and the heat insulating member 20 can be accommodated on the basis of the volumes of the thermistor 17 and the heat insulating member 20. The cap 5 can be attached.

しかして、前記移動側支持パイプ１６は、基台２８に上下動機構Ｄを介して上下自在に取付け、基台２８はコンロＫの任意の固定部に固定状態に取付ける。
即ち、調理の際に上下する炊事具２の底面に当接した当接体１５が、上下動機構Ｄにより炊事具２の上下動に追随して上下して常時炊事具２の底面に当接するようにする。
前記基台２８は、平面視概ね矩形状のベース２９に、上部を閉塞した円筒形状のケーシング３０を固定状態に取付け、ケーシング３０の中央に固定側支持筒３１の下部を固定する。 Thus, the moving side support pipe 16 is attached to the base 28 via the vertical movement mechanism D so as to freely move up and down, and the base 28 is fixedly attached to an arbitrary fixing portion of the stove K.
That is, the abutment body 15 that comes into contact with the bottom surface of the cooking utensil 2 that moves up and down during cooking follows the vertical movement of the cooking utensil 2 by the vertical movement mechanism D and always comes into contact with the bottom surface of the cooking utensil 2. Like that.
The base 28 is fixed to a base 29 having a substantially rectangular shape in plan view, and a cylindrical casing 30 whose upper portion is closed is fixedly fixed, and the lower portion of the fixed support cylinder 31 is fixed to the center of the casing 30.

しかして、前記温度検出装置１は、前記当接体１５を前記炎口７（バーナキャップ５）より上方に位置させると共に、前記上下動機構ＤはバーナＢの炎口７（バーナキャップ５）より下方に位置するように構成する。
即ち、前記当接体１５は炊事中の炊事具２の下面に当接しているのであるから、当然、当接体１５は炎口７（バーナキャップ５）より上方位置し、一方、上下動機構Ｄは炎口７（バーナキャップ５）より下方に位置させて、前記したように当接体１５を小径のバーナキャップ５のバーナＢに装着可能にする。
前記上下動機構ＤはバーナＢの炎口７（バーナキャップ５）より下方に位置させることが要点であり、前記移動側支持パイプ１６（当接体１５）が前記固定側支持筒３１に対して上下自在にすればよく、その構成は任意であるが、以下、一例を示す。 Thus, the temperature detection device 1 positions the contact body 15 above the flame opening 7 (burner cap 5), and the vertical movement mechanism D moves from the flame opening 7 (burner cap 5) of the burner B. It is configured to be positioned below.
That is, since the contact body 15 is in contact with the lower surface of the cooking utensil 2 during cooking, the contact body 15 is naturally positioned above the flame outlet 7 (burner cap 5), while the vertical movement mechanism. D is positioned below the flame outlet 7 (burner cap 5) so that the contact body 15 can be attached to the burner B of the small-diameter burner cap 5 as described above.
It is essential that the vertical movement mechanism D is positioned below the flame opening 7 (burner cap 5) of the burner B, and the moving side support pipe 16 (contact body 15) is in relation to the fixed side support cylinder 31. The configuration can be arbitrarily set up and down, and the configuration is arbitrary, but an example will be shown below.

And fix. Reference numeral 39 denotes a detent groove formed on the outer periphery of the flange 35.

前記固定側支持筒３１の内周には前記移動側支持パイプ１６の下部を上下動自在に挿入し、前記移動側支持パイプ１６の上下中間所定位置にはフランジ部４０を固定する。フランジ部４０には円筒４１の上端を固定し、円筒４１は前記鍔３５の外周に上下動自在に取付ける。
円筒４１は金属薄板で形成され、下部は細く絞られ小径部４２に形成し、小径部４２は固定側支持筒３１の外周に位置する。
円筒４１は、円筒４１と小径部４２の境の段部４３が前記鍔３５の下面に当接するように、固定側支持筒３１の下側から挿通させ、鍔３５の上面と前記フランジ部４０の間に円筒４１が常時上動するように付勢するコイルバネ４４を挿入し、円筒４１の上端には前記フランジ部４０を上側から被せて固定し、円筒４１内に煮汁が入らないようにしている。
前記円筒４１の外周には、前記回り止め溝３９が係合して回り止めになる突条４５を円筒４１の母線方向に長く形成する。
サーミスター１７にはリード線２１の先端を接続し、リード線２１は移動側支持パイプ１６および円筒４１および固定側支持筒３１の夫々の内側に挿通し、当接体１５の上下に合わせて昇降移動する。 A lower portion of the moving side support pipe 16 is inserted into the inner periphery of the fixed side support cylinder 31 so as to be movable up and down, and a flange portion 40 is fixed at a predetermined position between the upper and lower sides of the moving side support pipe 16. An upper end of a cylinder 41 is fixed to the flange portion 40, and the cylinder 41 is attached to the outer periphery of the flange 35 so as to be movable up and down.

Therefore, when the cooking utensil 2 is removed from the stove, the contact body 15 moves up, and when the cooking utensil 2 is placed on the stove, the contact body 15 moves down.

しかして、当接体１５内にはサーミスター１７を設け、当接体１５は移動側支持パイプ１６の上部のサーミスター取付部２５に断熱部材２０を介在させて設け、前記サーミスター取付部２５は筒状の当接体１５の取付を容易にするために僅かに大径に形成しているから、移動側支持パイプ１６のサーミスター取付部２５部分が最も径が大きく、最も径が大きいサーミスター取付部２５の直径を可及的に小径に形成でき、前記コンロＫの小径のバーナキャップ５への装着を可能にする。
即ち、従来は、上下動機構Ｄ部分の径が大きくバーナキャップ５の挿入孔６の内周面と干渉を避けるため、上下動機構Ｄがバーナキャップ５の挿入孔６に入らないようにバーナキャップ５の炎口７より上方に設けていた。そのため、径の小さいバーナキャップ５では挿入孔６の径が細く、取付けられないという制約があったが、本願では、上下動機構Ｄを炎口７より下方の移動側支持パイプ１６と固定側支持筒３１との間に設けているから、このような制約がなく、何れのバーナＢでも取付けられる。
また、炎口７より下方に上下動機構Ｄがあるため、コイルバネ４４の耐熱性能はそれ程要求されなくなるので、その分、コストを低くする。 Thus, the thermistor 17 is provided in the contact body 15, and the contact body 15 is provided in the thermistor mounting portion 25 at the upper part of the moving side support pipe 16 with the heat insulating member 20 interposed therebetween. Is formed with a slightly larger diameter in order to facilitate the attachment of the cylindrical abutment 15, the thermistor mounting portion 25 portion of the moving side support pipe 16 has the largest diameter and the largest diameter of the circuit. The diameter of the mr mounting portion 25 can be formed as small as possible, and the stove K can be attached to the small-diameter burner cap 5.
That is, conventionally, in order to avoid interference with the inner peripheral surface of the insertion hole 6 of the burner cap 5 because the diameter of the vertical movement mechanism D is large, the burner cap is prevented from entering the insertion hole 6 of the burner cap 5. 5 above the flame outlet 7. Therefore, the burner cap 5 with a small diameter has a restriction that the diameter of the insertion hole 6 is thin and cannot be attached. In the present application, the vertical movement mechanism D is connected to the movable side support pipe 16 and the fixed side support below the flame opening 7. Since it is provided between the cylinder 31, there is no such restriction and any burner B can be attached.
Further, since the vertical movement mechanism D is located below the flame opening 7, the heat resistance performance of the coil spring 44 is not so much required, and the cost is reduced accordingly.

しかして、前記上下動機構Ｄは、固定側支持筒３１の上端に固定した鍔３５に、移動側支持パイプ１６の下部を挿入し、次に、鍔３５の上面と移動側支持パイプ１６に固定のフランジ部４０の間に透孔３８が常時上動するように付勢するコイルバネ４４を挿入し、鍔３５の下面に円筒４１の小径部４２の段部４３を当接させて、円筒４１の上端にフランジ部４０を上側から被せて固定しているから、移動側支持パイプ１６は、上側のサーミスター取付部２５から下側部分まで全て塞がれて煮汁が入らない。
したがって、移動側支持パイプ１６および固定側支持筒３１内に挿入したリード線２１は移動側支持パイプ１６の上下に追従して円滑に移動する。
そのため、一旦、下動した当接体１５の戻りは、迅速且つ確実である。 Thus, the vertical movement mechanism D inserts the lower part of the movable support pipe 16 into the flange 35 fixed to the upper end of the fixed support cylinder 31, and then fixes the upper surface of the flange 35 and the movable support pipe 16. A coil spring 44 that urges the through hole 38 to always move upward is inserted between the flange portions 40, and the step portion 43 of the small diameter portion 42 of the cylinder 41 is brought into contact with the lower surface of the flange 35, so that the cylinder 41 Since the flange portion 40 is put on the upper end and fixed from the upper side, the moving side support pipe 16 is completely closed from the upper thermistor mounting portion 25 to the lower side portion so that the broth does not enter.
Accordingly, the lead wire 21 inserted into the moving side support pipe 16 and the fixed side support cylinder 31 moves smoothly following the upper and lower sides of the moving side support pipe 16.
Therefore, the return of the contact body 15 once moved down is quick and reliable.

即ち、移動側支持パイプ１６の上部と当接体１５の間に上下動機構Ｄを設けた従来型であると、移動側支持パイプ１６の下部は開放され、この付近でリード線２１が露出することがあり、露出したリード線２１に煮汁が付着して固まり、当接体１５の上下に支障を来すことがあるが、本願の上下動機構Ｄは、ベースベース２９に上部を閉塞した円筒形状のケーシングケーシング３０を固定状態に取付け、ケーシング３０の中央に固定側支持筒３１の下部を固定し、この固定側支持筒３１に移動側支持パイプ１６を挿入し、移動側支持パイプ１６と固定側支持筒３１の摺動部分の周囲を円筒４１と小径部４２により包囲し、円筒４１内にコイルバネ４４を挿入して構成しているから、上下動機構Ｄは、当接体１５を上下動させる構成でありながら、移動側支持パイプ１６と固定側支持筒３１の互いの上下動する部分を煮汁から遮断するカバーの作用も奏する。
したがって、当接体１５の上下を円滑・確実にする。 That is, in the conventional type in which the vertical movement mechanism D is provided between the upper part of the moving side support pipe 16 and the contact body 15, the lower part of the moving side support pipe 16 is opened, and the lead wire 21 is exposed in the vicinity. In some cases, the boiled juice adheres to the exposed lead wire 21 and hardens, and the contact body 15 may be disturbed up and down. The vertical movement mechanism D of the present application is a cylinder whose upper portion is closed by the base base 29. A casing casing 30 having a shape is attached in a fixed state, a lower portion of a fixed side support cylinder 31 is fixed at the center of the casing 30, and the movable side support pipe 16 is inserted into the fixed side support cylinder 31 to be fixed to the movable side support pipe 16. Since the periphery of the sliding portion of the side support cylinder 31 is surrounded by the cylinder 41 and the small diameter portion 42 and the coil spring 44 is inserted into the cylinder 41, the vertical movement mechanism D moves the contact body 15 up and down. Although it is a structure to let Also Kanade action of a cover for blocking the vertical movement portion of each other of the movable support pipe 16 and the fixed-side support cylinder 31 from broth.
Therefore, the upper and lower sides of the contact body 15 are made smooth and reliable.

この場合、小径部４２の内周と固定側支持筒３１の外周および固定側支持筒３１の内周と移動側支持パイプ１６の外周とは夫々所定の隙間を有して緩く嵌合させているから、当接体１５に炊事具２が斜めに当たっても、移動側支持パイプ１６は振り子のように上部を左右に振って炊事具２の下面と密着する。
そして、この当接体１５の振れ角度の調節は、移動側支持パイプ１６の外径と固定側支持筒３１の内径により隙間を変えることで行えるので、非常に容易に行える。
即ち、本願の当接体１５は、小径に形成されているため、炊事具２との当接面積が小さく、移動側支持パイプ１６の軸心を中心にその放射方向に当接体１５が振れることで、炊事具２の下面との密着性を向上させることができ、好適である。 In this case, the inner circumference of the small-diameter portion 42 and the outer circumference of the fixed-side support cylinder 31 and the inner circumference of the fixed-side support cylinder 31 and the outer circumference of the moving-side support pipe 16 are loosely fitted with predetermined gaps. Therefore, even if the cooking utensil 2 strikes the abutment body 15 at an angle, the moving side support pipe 16 is in close contact with the lower surface of the cooking utensil 2 by swinging the upper part left and right like a pendulum.
The swing angle of the contact body 15 can be adjusted by changing the gap according to the outer diameter of the moving-side support pipe 16 and the inner diameter of the fixed-side support cylinder 31, and thus can be performed very easily.
That is, since the contact body 15 of the present application has a small diameter, the contact area with the cooker 2 is small, and the contact body 15 swings in the radial direction around the axis of the moving support pipe 16. Thereby, adhesiveness with the lower surface of the cooking utensil 2 can be improved, and it is suitable.

しかして、固定側支持筒３１に固定の鍔３５に、小径部４２の段部４３が当たって、移動側支持パイプ１６の上動を停止させるが、鍔３５と移動側支持パイプ１６とが直接接触していないので、摺動性能を向上させる。
即ち、鍔３５と移動側支持パイプ１６では、材質が相違するため、鍔３５の透孔３８に直接移動側支持パイプ１６を挿入すると、摺動抵抗が大きくなるが、移動側支持パイプ１６は同じステンレス（ＳＵＳ３０４）等の材質で形成した固定側支持筒３１に挿入しているので、摺動抵抗を小さくでき、その結果、当接体１５の上下を円滑・確実にする。 Accordingly, the stepped portion 43 of the small-diameter portion 42 hits the flange 35 fixed to the fixed-side support cylinder 31 to stop the upward movement of the movable-side support pipe 16. However, the flange 35 and the movable-side support pipe 16 are directly connected to each other. Since it is not in contact, the sliding performance is improved.
That is, since the material of the flange 35 and the moving side support pipe 16 is different, sliding resistance increases when the moving side support pipe 16 is directly inserted into the through hole 38 of the flange 35, but the moving side support pipe 16 is the same. Since it is inserted in the fixed-side support cylinder 31 formed of a material such as stainless steel (SUS304), the sliding resistance can be reduced, and as a result, the contact body 15 can be smoothly and vertically moved.
