　以下、ヒータ１０の一例について図面を参照して説明する。本開示のヒータ１０は、図１に示すように、第１部材１と、発熱抵抗体２と、第２部材３とを有している。 Hereinafter, an example of the heater 10 will be described with reference to the drawings. As illustrated in FIG. 1, the heater 10 according to the present disclosure includes a first member 1, a heating resistor 2, and a second member 3.
　第１部材１は、発熱抵抗体２を保護するための部材である。第１部材１は、棒状の部材である。ここで、棒状の部材とは、長さ方向を有する部材であることを意味しており、第１部材１は、板状または柱状の部材であってもよいし、筒状の部材であってもよい。第１部材１は、絶縁材料からなり、例えば、セラミック材料を有していてもよい。 The first member 1 is a member for protecting the heating resistor 2. The first member 1 is a rod-shaped member. Here, the rod-shaped member means a member having a length direction, and the first member 1 may be a plate-shaped or column-shaped member, or may be a cylindrical member. Is also good. The first member 1 is made of an insulating material, and may have, for example, a ceramic material.
　第１部材１の寸法は、例えば第１部材１が板状の場合は、主面の形状が長方形であるときに、長辺の長さを５～２０ｍｍに、短辺の長さを１～１０ｍｍに、厚さを０．０８～１ｍｍにすることができる。また、第１部材１は、端部に被加熱物を挿入しやすいように、先端が細くなっていてもよい。また、第１部材１は、先端または全体が反ってもよい。 For example, when the first member 1 has a plate shape, the length of the long side is set to 5 to 20 mm and the length of the short side is set to 1 to 20 when the shape of the main surface is rectangular. The thickness can be 0.08 to 1 mm for 10 mm. Further, the first member 1 may have a tapered tip so that an object to be heated can be easily inserted into the end. Further, the first member 1 may be warped at the tip or the whole.
　また、第１部材１が筒状である場合は、長手方向の長さを５～２０ｍｍに、内径を８～２０ｍｍに、外径を８．５～２２ｍｍにすることができる。 When the first member 1 is cylindrical, the length in the longitudinal direction can be 5 to 20 mm, the inner diameter can be 8 to 20 mm, and the outer diameter can be 8.5 to 22 mm.
　発熱抵抗体２は、被加熱物を加熱するための部材である。発熱抵抗体２は、例えば第１部材１の表面または内部に設けることができる。発熱抵抗体２は、例えば線状または帯状の部材であってもよい。発熱抵抗体２は、例えば折返し部を有していてもよい。発熱抵抗体２は、外部電源に電気的に接続されていてもよい。発熱抵抗体２は、電流が流れることによって発熱し、被加熱物を加熱することができる。発熱抵抗体２は、第１部材１の長手方向に沿って設けられていてもよい。 The heating resistor 2 is a member for heating an object to be heated. The heating resistor 2 can be provided, for example, on the surface or inside of the first member 1. The heating resistor 2 may be, for example, a linear or band-shaped member. The heating resistor 2 may have, for example, a folded portion. The heating resistor 2 may be electrically connected to an external power supply. The heating resistor 2 generates heat when a current flows, and can heat an object to be heated. The heating resistor 2 may be provided along the longitudinal direction of the first member 1.
　発熱抵抗体２は、例えばタングステン、モリブデン、クロム、これらの炭化物または金、銀、パラジウム、白金等の金属からなる。また、発熱抵抗体２は、金属以外の成分として、アルミナまたは窒化ケイ素等を有していてもよい。発熱抵抗体２の寸法は、例えば長さが５～５０ｍｍ、幅が０．２～２ｍｍ、厚さが０．００５～０．１ｍｍである。 The heating resistor 2 is made of, for example, tungsten, molybdenum, chromium, a carbide thereof, or a metal such as gold, silver, palladium, or platinum. Further, the heat generating resistor 2 may have alumina, silicon nitride, or the like as a component other than the metal. The dimensions of the heating resistor 2 are, for example, 5 to 50 mm in length, 0.2 to 2 mm in width, and 0.005 to 0.1 mm in thickness.
　発熱抵抗体２は、第１部材１の先端から後端まで設けられていてもよい。また、図１３および図１４に示すように、発熱抵抗体２は、引き出し部５および導線７に接続されていてもよい。このときに、引き出し部５は、発熱抵抗体２よりも電気抵抗値を小さくすることができる。これにより、引き出し部５における発熱を低減することができる。 The heating resistor 2 may be provided from the front end to the rear end of the first member 1. As shown in FIGS. 13 and 14, the heating resistor 2 may be connected to the lead portion 5 and the conductor 7. At this time, the drawer 5 can have an electric resistance value smaller than that of the heating resistor 2. Thereby, heat generation in the drawer 5 can be reduced.
　本開示のヒータ１０においては、図１に示すように、第１部材１の端面に接合されており第１部材１よりも熱伝導率が低い第２部材３を有している。これにより、ヒータ１０の先端温度を下げつつ、第１部材１の端面を第２部材３によって保護することができる。その結果、ヒータ１０を被加熱物に突き刺したときに、被加熱物の奥まで高温になるおそれを低減しつつ、ヒータ１０の耐久性を高めることができる。 ヒ ー タ As shown in FIG. 1, the heater 10 of the present disclosure has the second member 3 joined to the end surface of the first member 1 and having a lower thermal conductivity than the first member 1. Thereby, the end surface of the first member 1 can be protected by the second member 3 while lowering the tip temperature of the heater 10. As a result, when the heater 10 is pierced into the object to be heated, the durability of the heater 10 can be increased while reducing the possibility that the temperature will reach the depth of the object to be heated.
　第２部材３は、第１部材１の端面に接合されており、これにより、ヒータ１０の先端の強度を高めることができる。第２部材３は、例えば板状、円錐状、円錐台状または円柱状であってもよく、これらの形状を組み合わせたものであってもよい。図１に示す例では、第２部材３は、円柱状である。第２部材３は、例えばジルコニアまたはアルミナ等のセラミック部材であってもよい。第１部材１よりも熱伝導率が低い第２部材３の例としては、例えば、第１部材１がアルミナのときは、第２部材３をジルコニアに、第１部材１が窒化アルミニウムのときは、第２部材３を窒化珪素に、することができる。 The second member 3 is joined to the end surface of the first member 1, whereby the strength of the tip of the heater 10 can be increased. The second member 3 may be, for example, a plate, a cone, a truncated cone, or a column, or a combination of these shapes. In the example shown in FIG. 1, the second member 3 has a columnar shape. The second member 3 may be a ceramic member such as zirconia or alumina. As an example of the second member 3 having a lower thermal conductivity than the first member 1, for example, when the first member 1 is alumina, the second member 3 is zirconia, and when the first member 1 is aluminum nitride, The second member 3 can be made of silicon nitride.
　また、第１部材１がアルミナを有しており、第２部材３がジルコニアを有していてもよい。これにより、ヒータ１０先端の第２部材３が弾性の高い部材であるため、ヒータ１０を被加熱物に突き刺したときに、第２部材３が破損するおそれを低減することができる。 The first member 1 may include alumina, and the second member 3 may include zirconia. Thereby, since the second member 3 at the tip of the heater 10 is a member having high elasticity, it is possible to reduce the risk of the second member 3 being damaged when the heater 10 pierces the object to be heated.
　また、図２に示すように、第２部材３が先端に向かって細くなる形状を有していてもよい。これにより、被加熱物をヒータ１０の先端に突き刺しやすくすることができる。図２に示す例では、第２部材３は、円錐状である。 Also, as shown in FIG. 2, the second member 3 may have a shape that becomes thinner toward the tip. Thereby, it is possible to easily pierce the heated object with the tip of the heater 10. In the example shown in FIG. 2, the second member 3 has a conical shape.
　また、第２部材３が先端に向かって細くなる形状としては、図３に示すように、円柱部分と円錐部分とが組み合わされた形状であってもよい。図３に示す例では、円柱部分の底面が、第１部材１の端面と同径の円形状であり、円錐部分の底面も同径の円形状である。本例の第２部材３の形状は、図２に示す形状に比べて、第２部材３の体積を大きくすることができる。熱伝導率が低い第２部材３の体積を大きくすることで、ヒータ１０の先端温度をさらに下げつつ、第１部材１の端面を第２部材３によって保護することができる。 As the shape in which the second member 3 becomes thinner toward the distal end, as shown in FIG. 3, a shape in which a cylindrical portion and a conical portion are combined may be used. In the example shown in FIG. 3, the bottom surface of the cylindrical portion has a circular shape having the same diameter as the end surface of the first member 1, and the bottom surface of the conical portion has a circular shape having the same diameter. The shape of the second member 3 of the present example can increase the volume of the second member 3 as compared with the shape shown in FIG. By increasing the volume of the second member 3 having a low thermal conductivity, the end surface of the first member 1 can be protected by the second member 3 while further lowering the temperature at the tip of the heater 10.
　上記のような第２部材３が先細状の場合、先端部分は曲面状（Ｒ状）であってもよい。これにより、ヒータ１０を被加熱物に突き刺したときに、第２部材３の先端部分が破損するおそれを低減することができる。 場合 When the second member 3 is tapered, the tip portion may be curved (R-shaped). Thereby, when the heater 10 pierces the object to be heated, it is possible to reduce the possibility that the distal end portion of the second member 3 is damaged.
　また、図４に示すように、第１部材１と第２部材３とがガラス材料４により接合されていてもよい。これにより、第１部材１と第２部材３との接合の強度を高めることができる。また、図１３および図１４に示すように、第１部材１は円柱状の部材であって、第１部材１の端面の形状は円形状であって、第２部材３のうち第１部材１に接合する面の形状も円形状であってもよい。この場合は、ガラス接合の接合面積を広くすることができるため、ヒータ１０の強度をより高めることができる。 (4) As shown in FIG. 4, the first member 1 and the second member 3 may be joined by a glass material 4. Thereby, the bonding strength between the first member 1 and the second member 3 can be increased. As shown in FIGS. 13 and 14, the first member 1 is a columnar member, and the shape of the end surface of the first member 1 is circular. The shape of the surface to be joined may be circular. In this case, since the bonding area of the glass bonding can be increased, the strength of the heater 10 can be further increased.
　また、図５に示すように、第１部材１と第２部材３とがガラス材料４により接合されているとともに、第１部材１と第２部材３の外周面がガラス材料４で覆われていてもよい。これにより、ヒータ１０を被加熱物に突き刺したときに、ヒータ１０の表面に被加熱物が付着するおそれを低減することができる。その結果、被加熱物が付着した部位におけるヒータ１０の腐食を低減し、ヒータ１０が破損するおそれを低減することができる。その結果、ヒータ１０の耐久性を高めることができる。なお、ヒータ１０は、第１部材１の外周面の一部または全部と第２部材３の外周面の一部または全部とがガラス材料４で覆われていてもよい。また、ヒータ１０は、第１部材１の外周面の一部または全部がガラス材料４で覆われていて、第２部材３の外周面はガラス材料４で覆われていなくてもよく、第２部材３の外周面の一部または全部がガラス材料４で覆われていて、第１部材１の外周面はガラス材料４で覆われていなくてもよい。 Further, as shown in FIG. 5, the first member 1 and the second member 3 are joined by a glass material 4, and the outer peripheral surfaces of the first member 1 and the second member 3 are covered with the glass material 4. You may. Thereby, when the heater 10 pierces the object to be heated, the possibility that the object to be heated adheres to the surface of the heater 10 can be reduced.
