Description

本発明は、被加熱センサ、特に発熱体を用いて加熱する温度プローブを収容するための断熱体に関する。   The present invention relates to a heat insulator for housing a sensor to be heated, particularly a temperature probe heated using a heating element.

特許文献１から、実施例で温度プローブに加熱抵抗を介して熱的フィードバック信号が作用する蓄熱式暖房器具および室温の制御方法が知られている。加熱抵抗は熱的に温度プローブと結合しており、それによってここでヒータの通電時間が制御される。ヒータの接続は、温度プローブが比較器Ｐにより加熱抵抗に電圧を印加し、それによってよりヒータのプローグを加熱するので、通電時間は短くなる。   From Patent Document 1, a regenerative heating appliance in which a thermal feedback signal acts on a temperature probe via a heating resistor in an embodiment and a method for controlling a room temperature are known. The heating resistor is thermally coupled to the temperature probe, whereby the energization time of the heater is controlled here. As for the connection of the heater, since the temperature probe applies a voltage to the heating resistor by the comparator P and thereby heats the heater probe, the energization time is shortened.

特許文献２から蓄熱式暖房器具の充電制御装置が知られており、この装置はそのスイッチングコンタクトの制御のために残熱プローブ（温度プローブ）と制御発熱体とを有する。制御発熱体はその入口で自体公知の制御装置によって発生される接続時間信号（ＥＤ信号）によって作動される。   Patent Document 2 discloses a charge control device for a regenerative heating appliance, and this device has a residual heat probe (temperature probe) and a control heating element for controlling the switching contact. The control heating element is activated at its inlet by a connection time signal (ED signal) generated by a control device known per se.

さらに温度プローブおよび加熱抵抗を断熱体の中に入れた蓄熱式暖房器具が市場で知られている。前記装置は通常好適な断熱性質を有するケイ酸カルシウムから製造される。   Furthermore, regenerative heating appliances are known in the market in which a temperature probe and a heating resistor are placed in an insulator. Such devices are usually made from calcium silicate having suitable thermal insulation properties.

ケイ酸カルシウムからなる前記断熱体は機械的に切削加工することができ、かつ脆性であり、好適な断熱性質を有する。

図１は本発明の一実施の形態に係る被加熱センサの収容のための断熱体の構成図である。   FIG. 1 is a configuration diagram of a heat insulator for housing a heated sensor according to an embodiment of the present invention.

より詳細には、（ａ）は断熱体のシェル内の発熱体および温度プローブを示す図、（ｂ）は発熱体の貫通接続部と温度プローブの毛管とを備えた断熱体の正面図である。   More specifically, (a) is a view showing a heating element and a temperature probe in the shell of the heat insulator, and (b) is a front view of the heat insulator provided with a through connection portion of the heat generator and a capillary of the temperature probe. .

即ち、断熱体はそのため少なくとも２つの好ましくは同形状であるシェル２，４から構成される。使用する材料は、組成４７％ＳｉＯ２、０．５％ＴｉＯ２、４％Ｆｅ２Ｏ３、７％Ａｌ２Ｏ３、２１％ＭｇＯ、２％ＣａＯ、０．５％Ｎａ２Ｏ、１１％Ｋ２Ｏ、ＬＯＩ７％（Ｖ−１１００／４７５）を有する、例えばスカモル社のバーミキュライトである。この材料は成形金型で圧縮かつ結合される。シェル２，４を接合することによりこのシェル２，４は内部に中空空間を有し、その中に温度プローブ９と発熱体６が置かれる。発熱体６および温度プローブ９は、好ましい方法で断熱体１の端部に保持され、片側で接続管１３，１４ならびに温度プローブ９の毛管３が導出される。中空空間によって温度プローブ９と発熱体６が断熱体１の内壁から約５ｍｍ離れている。断熱体１の内壁とセンサもしくは発熱体６との間の間隔は、好ましくは１から８ｍｍになる。 That is, the thermal insulator is therefore composed of at least two shells 2, 4 that are preferably of the same shape. Materials used, the composition 47% SiO 2, 0.5% TiO 2, 4% Fe 2 O 3, 7% Al 2 O 3, 21% MgO, 2% CaO, 0.5% Na 2 O, 11% K having 2 O, LOI7% (V- 1100/475), vermiculite, for example Sukamoru Corporation. This material is compressed and bonded in a mold. By joining the shells 2, 4, the shells 2, 4 have a hollow space in which the temperature probe 9 and the heating element 6 are placed. The heating element 6 and the temperature probe 9 are held at the end of the heat insulator 1 in a preferred manner, and the connecting tubes 13 and 14 and the capillary tube 3 of the temperature probe 9 are led out on one side. Due to the hollow space, the temperature probe 9 and the heating element 6 are separated from the inner wall of the heat insulator 1 by about 5 mm. The distance between the inner wall of the heat insulator 1 and the sensor or heating element 6 is preferably 1 to 8 mm.

絶縁体によって、プローブを一定の温度に加熱する必要がある加熱エネルギーが大幅に減少する。発熱体６および温度プローブ９を断熱体１のシェル２，４の中に密閉して保持することによって、熱損失は断熱体の外面を介してのみ生じる。さらに発熱体６および温度プローブ９が断熱体１の外部で周囲空気と接触しないことが有利である。   The insulator greatly reduces the heating energy required to heat the probe to a constant temperature. By holding the heating element 6 and the temperature probe 9 hermetically in the shells 2 and 4 of the thermal insulator 1, heat loss occurs only through the outer surface of the thermal insulator. Furthermore, it is advantageous that the heating element 6 and the temperature probe 9 do not come into contact with the ambient air outside the insulation 1.

空気層５は、断熱体１の内部で温度最大約６０℃で約０．０２９Ｗ／ｍＫの熱伝導率を有する。それに対しバーミキュライトは前記温度で約０．１５Ｗ／ｍＫの熱伝導率、すなわち５倍の熱伝導率を有する。空気層５の変化によって、バーミキュライト絶縁体と空気系の全熱伝導率は約６０℃で０．０８Ｗ／ｍＫの熱伝導率を有するケイ酸カルシウム絶縁体に適合される。温度プローブ９と発熱体６のシステムは不変の状態に維持することができ、熱伝導率の適合は空気層５と断熱体１の厚さを介して行われる。   The air layer 5 has a thermal conductivity of about 0.029 W / mK at a maximum temperature of about 60 ° C. inside the heat insulator 1. On the other hand, vermiculite has a thermal conductivity of about 0.15 W / mK at the above temperature, that is, a thermal conductivity of 5 times. By changing the air layer 5, the total thermal conductivity of the vermiculite insulator and the air system is adapted to a calcium silicate insulator having a thermal conductivity of 0.08 W / mK at about 60 ° C. The system of the temperature probe 9 and the heating element 6 can be kept unchanged, and the thermal conductivity adaptation is performed via the thickness of the air layer 5 and the insulation 1.

このように、断熱体１において、図１に示されるように、シェル２，４の中に温度プローブ９と発熱体６がある。シェル２，４の内壁１０と発熱体６も しくは温度プローブ９との間に空気層５がある。間隔８は、好ましくは１から８ｍｍになる。発熱体６の端部１１，１２は、ブッシング１５の中の両シェル２，４の間に保持される。同様に、毛管３および接続管１３，１４はブッシング１５によって保持される。シェル２，４は、図示しない組立ソケットから離間するために脚７を有する。   As described above, in the heat insulator 1, as shown in FIG. 1, the temperature probe 9 and the heating element 6 are in the shells 2 and 4. There is an air layer 5 between the inner wall 10 of the shell 2, 4 and the heating element 6 or the temperature probe 9. The spacing 8 is preferably 1 to 8 mm. Ends 11 and 12 of the heating element 6 are held between the shells 2 and 4 in the bushing 15. Similarly, the capillary 3 and the connecting tubes 13 and 14 are held by a bushing 15. The shells 2 and 4 have legs 7 to be separated from an assembly socket (not shown).

ブッシング１５は、好ましくは片側でシェル２，４によって形成されている。シェル２，４は、好ましくは同形状に形成されており、そのためこのシェルは金型で製造できる。   The bushing 15 is preferably formed by the shells 2, 4 on one side. The shells 2 and 4 are preferably formed in the same shape, so that they can be manufactured in a mold.

以上詳述したように、本発明によれば、被加熱センサ、特に発熱体を用いて加熱される温度プローブの収容の為の断熱体であって、前記断熱体１は、温度プローブ９および発熱体６が置かれる少なくとも２つのシェル２，４から構成され、少なくとも部分的に空気層が１５ｍｍまで前記断熱体１のシェル２，４の内壁１０と前記温度プローブ９および／または前記発熱体６との間にあることを特徴とする断熱体が提供される。   As described above in detail, according to the present invention, a heat insulator for housing a temperature probe heated using a sensor to be heated, particularly a heat generator, the heat insulator 1 includes a temperature probe 9 and a heat generator. An inner wall 10 of the shells 2, 4 of the thermal insulator 1 and the temperature probe 9 and / or the heating element 6 at least partially composed of at least two shells 2, 4 on which the body 6 is placed.

The heat generating body 6 may be anchored in the heat insulating body 1 at its end portions 11 and 12 so as to come into contact with the heat insulating body. The connecting pipes 13 and 14 of the heating element 6 and the capillary 3 or the connecting part of the heating element 6 may be guided to the outside through the bushing 15.
