温度条件が重要となつてくる。 Confining the object to be heated in a furnace and heating it
Heating furnaces are also used in drying chambers and the like, and are also used in analytical devices that examine the components of objects to be heated by heating, and in this case the temperature conditions of the objects to be heated are particularly important.
通常分析装置等で用いられる加熱炉では、炉内
中心の底面に被加熱体を置き、同被加熱体の周辺
に配設した熱源によつて加熱するが、被加熱体の
熱が炉底面を通つて外部に放熱されるのを防ぐた
め、耐熱レンガ・セラミツクス等の断熱材が被加
熱体の底部に配設されている。 In a heating furnace normally used for analysis equipment, the object to be heated is placed on the bottom of the center of the furnace, and the object is heated by a heat source placed around the object. In order to prevent heat from being radiated to the outside through the heating element, a heat insulating material such as heat-resistant brick or ceramics is placed at the bottom of the heated body.
従つて、被加熱体の底部は熱源からの熱を受け

つたく熱を受けることがなく、被加熱体の加熱は
その側面あるいは上部から行なわれることにな
る。これによつて被加熱体の底部の中央部の加熱
が、その他の部分より昇温が遅れることになる。 Therefore, the bottom of the object to be heated has a small area that receives heat from the heat source, and in some places it is not exposed to heat due to insulation, and the object to be heated is heated from its sides or top. It will be. As a result, heating of the central portion of the bottom of the object to be heated is delayed in temperature rise compared to other portions.
先に述べたような分析装置に用いる場合には、
被加熱体が一様に加熱昇温していくことが好まし
いのにもかかわらず、実際には被加熱体は温度勾
配を有していることになつている。 When used in an analytical device such as the one mentioned above,
Although it is preferable that the object to be heated is heated uniformly, the object to be heated actually has a temperature gradient.
本考案はこの欠点を排除するものであつて、空

熱炉を提供するものである。 The present invention eliminates this drawback, and provides a heating furnace in which a space is sealed and the object to be heated is heated by a heat source placed around the object to be heated, which is placed in the center of the space. , characterized in that the object to be heated is supported by a support made of a thermally conductive member, and a heat insulating material is interposed between the support and the bottom of the inner surface of the heating furnace, and its purpose is to:
An object of the present invention is to provide a heating furnace that can evenly heat and raise the temperature of an object to be heated.
以下本考案を第１図および第２図に示す一実施
例について説明する。 The present invention will be described below with reference to an embodiment shown in FIGS. 1 and 2.
１は被加熱体となる金属性の筒状の容器であつ
て、内部に試料２を収納し、加熱炉３で区画され
た炉内に閉じ込められている。 Reference numeral 1 denotes a metallic cylindrical container serving as a heated object, and a sample 2 is housed therein, and the sample 2 is confined in a furnace partitioned by a heating furnace 3 .
上記容器１は熱良導体部材（銅、鉄、ステンレ
ス鋼）からなる受台４および支持体５で支承され
ており、支持体５は断熱材６を介して加熱炉３の
内部底面に固定される。 The container 1 is supported by a pedestal 4 and a support 5 made of thermally conductive materials (copper, iron, stainless steel), and the support 5 is fixed to the inner bottom surface of the heating furnace 3 via a heat insulating material 6. .
７は加熱炉３内に配設され、上記容器１を加熱
する熱源となる赤外線ランプ、８は上記受台４お
よび支持体５に取り付けられる受熱板であつて、
熱良導体よりなつている。 7 is an infrared lamp disposed in the heating furnace 3 and serves as a heat source for heating the container 1; 8 is a heat receiving plate attached to the pedestal 4 and the support 5;
It is a good conductor of heat.
さて赤外線ランプ７に通電すると赤外線ランプ
７より赤外線が発せられ、容器１の側面と受熱板
８および支持体５が加熱される。 Now, when the infrared lamp 7 is energized, infrared rays are emitted from the infrared lamp 7, and the side surface of the container 1, the heat receiving plate 8, and the support body 5 are heated.
従つて容器１の側面は赤外線ランプ７によつて
直接、また容器１の底面は受熱板８および支持体
５に与えられた熱が受台４を介して間接的に加熱
昇温され、容器１の一様の加熱が行なわれ、試料
２も均一に加熱することが可能である。 Therefore, the side surface of the container 1 is directly heated by the infrared lamp 7, and the bottom surface of the container 1 is heated indirectly by the heat given to the heat receiving plate 8 and the support 5 via the pedestal 4, and the temperature of the container 1 is increased. Uniform heating is performed, and sample 2 can also be heated uniformly.
このように本考案の一実施例によると、加熱炉
３内に入れた被加熱体である容器１あるいは容器
１内に収納された試料等を均等に加熱することが
出来、昇温のむらが生じ難いので、分析装置用な
どに用いると分析の精度を高める効果がある。 As described above, according to one embodiment of the present invention, it is possible to uniformly heat the container 1, which is the object to be heated, placed in the heating furnace 3, or the sample stored in the container 1, thereby preventing uneven temperature rise. Therefore, using it for analysis equipment has the effect of increasing the accuracy of analysis.
なお、加熱炉３の底面に充分なる断熱材が配設
してある場合は、上記断熱材６をそれに変えて使
用しても良い。 Note that, if a sufficient heat insulating material is provided on the bottom surface of the heating furnace 3, the above heat insulating material 6 may be used instead.
