Abstract

A flexible planar heater (1) for controlling an incombustible surface having a harmless anti-firing function comprises a flexible electric resistor layer (2), a low-melting point soft resin layer (4) applied to one side of the flexible electric resistor layer (2), an incombustible electric conductor (12) applied to the low-melting-point soft resin layer (4), and a heat-resistant resin layer (5) applied to the surface of the incombustible electric conductor (12) and the surface of the low-melting-point soft resin layer (4) to which no incombustible electric conductor (12) is applied. The low-melting-point soft resin layer (4) dos not melt at the normal heating temperature ofthe electric resistor layer (2) and the incombustible electric conductor (12) when current is made to flow through the electric resistor layer (2). When the electric resistor layer (2) is heated to an abnormal heating temperature causing variation in the initial set resistance of the electric resistor layer (2) higher than the normal heating temperature, the low-melting-point soft resin layer (4) melts to form an electric short-circuit between the opposite faces of the electric resistor layer (2) and the incombustible electric conductor (12) in the portion of abnormal heating temperature.

Description

明 細 書 可撓性不燃面制御面発熱体 技術分野 本発明'は、 可撓性な面発熱体又は面状発熱体に関するものであり、 特に発 熱体の温度を安全な温度以下で制御する機能を備えた無害性な可撓性不燃面 制御面発熱体に関する。 背景技術 従来から、 塩化ビニール製外皮を有する可撓性カーボン発熱体は知られて いる。この種の発熱体は、 例えば寝具の保温や屋根の融雪等に使用されてい る。 また、その外に、 ニクロム線を S字型に配線した寝具やニクロム線を内 蔵した床暖房パネル等も多方面に使用されている。 又金属箔をプリン卜して 発熱源とした発熱体も使用されている。  TECHNICAL FIELD The present invention 'relates to a flexible surface heating element or a sheet heating element, and in particular, controls the temperature of a heating element below a safe temperature. The present invention relates to a harmless flexible non-combustible surface having a function. BACKGROUND ART A flexible carbon heating element having a vinyl chloride shell has been known. This type of heating element is used, for example, for keeping warm bedding and melting snow on a roof. In addition, beddings with S-shaped nichrome wires and floor heating panels with Nichrome wires are also used in various fields. Heating elements are also used, which are printed on metal foil and used as a heat source.
ここで、 金属構成の発熱体は、 高いエネルギーの消費があること及び安全 性と耐久性が保証されていないこと、 などの問題がある。 また、炭素粒子を 含むシリコン樹脂でフィルム板を形成した発熱体はしられているが、 この種 の発熱体は、 炭素粒子の分布及び温度制御装置を通じての発生温度制御が均 一でない欠点があるために、 面発熱体の面内温度を均一に保つことは困難で める。  Here, the metal heating element has problems such as high energy consumption, safety and durability are not guaranteed. In addition, although heating elements are used to form a film plate with silicon resin containing carbon particles, this type of heating element has the disadvantage that the distribution of carbon particles and the control of the generated temperature through a temperature control device are not uniform. Therefore, it is difficult to keep the in-plane temperature of the surface heating element uniform.
更に、合成樹脂系の緯糸に炭素粒子とゴム系樹脂を混合してカーボン液を 塗布して乾燥させた発熱緯糸と合成樹脂緯糸の経糸とを織り成し、塩化ビニ ル外皮で被 S艮し 面状発熱体も知られている。  Furthermore, the heating resin weft and the synthetic resin weft, which are obtained by mixing carbon particles and a rubber resin with a synthetic resin-based weft, applying a carbon solution, and drying, are woven, and are covered with a vinyl chloride sheath. Planar heating elements are also known.
しかし、 合成樹脂系を用いた発熱糸は糸め周囲に皮膜状にカーボン液が付着 しているため、このような炭素粒子と樹脂との混合液を塗布した発熱糸を用 いた面状発熱体は、折り曲げたり、力や加重を受けたときには損傷する場合も ある。 However, the heating liquid made of synthetic resin has carbon liquid attached in a film around the thread. Therefore, the sheet heating element using the heating yarn coated with the mixed liquid of the carbon particles and the resin may be damaged when it is bent or subjected to force or load.
以上説明の従来の面発熱体及び面状発熱体は、 いずれも面発熱体上の局部 的な異常温度上昇を防止する機能を有するものではなく、 異常温度上昇によ る劣化と共に加熱用電源に対するショート回路が発生する （以下、 単に 「シ ョートする」 という） ことがあり、 利用者に火傷を与え、 また場合により火 災を発生する危険もある。  Neither the conventional surface heating element nor the sheet heating element described above has a function of preventing a local abnormal temperature rise on the surface heating element. A short circuit may occur (hereinafter simply referred to as “shorting”), causing burns to the user and, in some cases, a fire.
この様な事故の発生を防止する一解決手段として、本願発明者は米国合衆国 特許第 5. 6 7 9. 2 7 7号により耐火面制御発熱体を提案した。 As one solution for preventing such an accident from occurring, the present inventor has proposed a fire-resistant surface control heating element according to US Patent No. 5,679,277.

第 7図は、 本発明に用いる電源制御器の回路構成例であり、 交流電源 FIG. 7 is an example of a circuit configuration of a power supply controller used in the present invention.
1 3の第 1の端子 1 3 aは、 O NZ O F F接点 1 4により基準電圧発生器 2 9の交流入力の一方及び、 ラッチング継電器 2 7に接続される。 ラッチ ング継電器 2 7 aの出力は、 発熱抵抗体 2の端子 1 0及び漏洩電流感知端 子 1 1に接続される。 交流電源 1 3の第 2の端子 1 3 bは、 基準電圧回路 2 9の交流入力の他方及び温度調節回路 2 0に接綾される。 The first terminal 13 a of 13 is connected to one of the AC inputs of the reference voltage generator 29 and the latching relay 27 by an ONZOFF contact 14. The output of the latching relay 27 a is connected to the terminal 10 of the heating resistor 2 and the leakage current sensing terminal 11. The second terminal 13 b of the AC power supply 13 is connected to the other of the AC inputs of the reference voltage circuit 29 and the temperature control circuit 20.
基準電圧発生回路 2 9には、 整流器 1 5及び電圧調整器 3 0が含まれ ている。 基準電圧発生回路 2 9の電圧調整出力 2 9 aは、 交流入力から直 流出力の送出までに若干の時定数を持たせた時定数付整流回路 2 5の入力 に用いられる。 不燃紙良導体 1 2の漏洩電流感知端子 1 1の出力は、 時定 数付整流回路 2 5の第 2の入力に接続される。  The reference voltage generation circuit 29 includes a rectifier 15 and a voltage regulator 30. The voltage adjustment output 29 a of the reference voltage generation circuit 29 is used as an input to a rectifier circuit 25 with a time constant having a slight time constant from the AC input to the transmission of the DC output. The output of the leakage current sensing terminal 11 of the non-combustible paper good conductor 12 is connected to the second input of the rectifier circuit 25 with a time constant.
発熱抵抗体 2と不燃紙良導体 3との間の低融点軟質樹脂 4は、 8 0 °C以 下の通常温度であれば漏洩電流の発生を防止する程度の高抵抗値を有して いる。 時定数付整流回路 2 5には、 その入力の一つで基準電圧発生回路 2 9からの調整された基準電圧 2 9 aを受ける整流器 1 6及び、 更にその 他の入力で不燃紙良導体 1 2からの端子 1 1の出力が含まれる。 整流器 1 6の整流出力は、 並列に継電コイル 2 6及び、 必要な時定数に対応する容 量のコンデンサ 1 7に接続される。  The low-melting soft resin 4 between the heating resistor 2 and the non-combustible paper good conductor 3 has such a high resistance value as to prevent generation of a leakage current at a normal temperature of 80 ° C. or lower. The rectifier circuit 25 with a time constant includes a rectifier 16 that receives the adjusted reference voltage 29 a from the reference voltage generation circuit 29 at one of its inputs, and a non-combustible paper conductor 1 2 at another input. The output of terminal 11 from is included. The rectified output of the rectifier 16 is connected in parallel to a relay coil 26 and a capacitor 17 having a capacity corresponding to a required time constant.
温度調節回路 2 0は、 コントロールスィッチ 2 3を含み、 入力の一つで 電源 1 3の出力 1 3 bを受けとる。 コント口一ラスィツチ 2 3の出力は、 ラッチング継電器 2 7 bに接続されている。 ラッチング継電器 2 7 bの他 方の端子は、 発熱抵抗体 2の第 2の端子に接続される。 整流回路 2 1は、 第 2図に示されたように耐熱樹脂層 5の下面に、 その表面部の温度を感 知するために配置された感熱線 Aからの入力を受ける。 整流回路 2 1の出 力は、 例えば、 5 0 °Cの設定温度に対応する基準電圧と比較するために温 度比較器 2 2の入力に接続される。 温度比較器 2 2の出力は、 コントロー ルスイッチ 2 3へのコントロ一ル出力として用いられる。 The temperature control circuit 20 includes a control switch 23 and receives an output 13 b of the power supply 13 at one of the inputs. The output of the control switch 2 3 is Connected to latching relay 27b. The other terminal of the latching relay 27 b is connected to the second terminal of the heating resistor 2. The rectifier circuit 21 receives an input from a heat-sensitive wire A arranged on the lower surface of the heat-resistant resin layer 5 to sense the temperature of the surface as shown in FIG. The output of the rectifier circuit 21 is connected to the input of a temperature comparator 22 for comparison with a reference voltage corresponding to a set temperature of 50 ° C., for example. The output of the temperature comparator 22 is used as a control output to the control switch 23.
ラッチング継電器 2 7 a， 2 7 bの保持用接点は、 継電器コイルの不動 作により、通常 「開」 になっている。 平常の動作状態では、 ラッチング継 電器 2 7 a及び 2 7 bの接点は、 「接」なっている。 O N/O F Fスイツ チ 1 4力 「接」 になっている場合には、 抵抗体 2と熱感知線 Aへの電力は、 コントロールスィッチ 2 3の O N， O F Fにより、 以下のように制御され ている 。  The holding contacts of the latching relays 27a and 27b are normally open due to the non-operation of the relay coil. Under normal operating conditions, the contacts of the latching relays 27a and 27b are "connected". ON / OFF switch 1 4 When power is “contact”, power to resistor 2 and heat sensing line A is controlled as follows by turning ON / OFF control switch 23 .
整流回路 2 1は、 温度依存電圧を温度比較器 2 2に供給するために、 感 熱線 Aにより感知された温度により生じた電圧や電流における温度依存変 化に感応する。  The rectifier circuit 21 is sensitive to temperature-dependent changes in voltage and current caused by the temperature sensed by the heat-sensing wire A to supply the temperature-dependent voltage to the temperature comparator 22.
温度比較器 2 2は、 不燃紙良導体 1 2により感知された温度が最初の設定 値より低い場合には、 コント口一ルスィツチ 2 3へ作動信号を送る。 If the temperature sensed by the non-combustible paper good conductor 12 is lower than the initial set value, the temperature comparator 22 sends an activation signal to the control switch 23.
これはコントロールスィツチ 2 3を 「接」 にし、 そのスィツチ 2 3と通じ て、 平常は 「接」 であるラッチング継電器 2 7 a， 2 7 bを通じて抵抗体 2へ電力を供給する。 これにより、 抵抗体 2は加熱される。 感知された温 度が第 2の設定値を越えた場合には、 温度比較器 2 2は、 コント口—ルス イッチ 2 3から作動信号を除去し、 臨時的に熱の周波を停止する。 もし感 知した温度が再び最初の設定値より低い場合には、 熱は回復される。 This causes the control switch 23 to be "connected" and supplies power to the resistor 2 through the switch 23 and through the latching relays 27a and 27b which are normally "connected". Thereby, the resistor 2 is heated. If the sensed temperature exceeds the second set point, the temperature comparator 22 removes the activation signal from the control switch 23 and temporarily shuts off the heat frequency. If the sensed temperature is again below the initial set point, heat is restored.
不燃紙良導体 1 2と共に抵抗体 2及び、 電流遮断機構 2 4の全体の安全 温度を維持する為の温度調節回路 2 0が不良となった場合には、 発熱体 1 は、 永久に使用不能となる。 注目される欠陥の一つには、 O Nの状態にお 2 けるコントロールスィッチ 2 3の欠陥が含まれる。 これは、 抵抗体 2にお ける熱を調整出来なくさせる原因となる。 抵抗体 2のどの部分でも低融点 軟質熔解性樹脂層 4の熔解温度を越える場合には、 抵抗体 2における導体 と不燃紙良導体 1 2の間で電気的ショート回路が発生する。 不燃紙良導体 1 2で受ける発生漏洩電流や電圧は、 整流器 1 6の出力及び、 時定数付整 流回路 2 5における整流器 1 6の入力となる。 If the resistor 2 together with the non-combustible paper conductor 1 2 and the temperature control circuit 20 for maintaining the overall safe temperature of the current interrupting mechanism 24 become defective, the heating element 1 will be permanently disabled. Become. One of the notable defects is the ON state The control switch 23 contains two defects. This causes the heat in the resistor 2 to be uncontrollable. If any part of the resistor 2 exceeds the melting temperature of the low melting point soft melting resin layer 4, an electrical short circuit occurs between the conductor in the resistor 2 and the non-combustible paper good conductor 12. The leakage current and voltage generated by the non-combustible paper good conductor 12 become the output of the rectifier 16 and the input of the rectifier 16 in the rectifier circuit 25 with a time constant.
5 不燃紙良導体 1 2から電流が漏洩すると、 整流器 1 6は、 継電コイル 2 5 When current leaks from the non-combustible paper good conductor 1 2, the rectifier 16
6に作動信号を供給する。 そこで、 継電コイル 2 6の接点は、 ラッチング 継電器 2 7 a及び 2 7 bが通常 「接」 になっている接触を開放し、 保持接 点を 「接」 にする。 コンデンサ 1 7は、 最初の作動信号が除去されたとし ても短時間だけ継電コイル 2 6の動作電圧を維持する。 これにより、 ラッ チング継電器 2 7 a及び 2 7 bの開放は確実に行われ、 発熱の停止を確実 にさせる抵抗体 2の両端への電力を遮断する。 Supply the activation signal to 6. Therefore, the contact of the relay coil 26 releases the contact where the latching relays 27a and 27b are normally in "contact", and sets the holding contact point to "contact". The capacitor 17 maintains the operating voltage of the relay coil 26 for a short time even if the initial operation signal is removed. As a result, the latching relays 27a and 27b are reliably opened, and the power to both ends of the resistor 2 that ensures the stop of heat generation is cut off.
L 0 軟質熔解性シート 4の熔解点は、 電流遮断機構 2 4が抵抗体 2から電力 を除去させる温度を決定する。 材料の適切な選択は、 抵抗体 2が初期設定 抵抗に復元しない異常温度、 すなはち、 8 0 °C〜1 1 0 °C以内の熔解温度 を対象とする。 抵抗体 2は、 可撓性を有する炭素粒子と樹脂を溶剤で混合 した炭素案抵抗液を、 綿織布に含浸し乾燥した抵抗体である。  The melting point of the L 0 soft-melt sheet 4 determines the temperature at which the current interruption mechanism 24 removes power from the resistor 2. Appropriate selection of the material is intended for an abnormal temperature at which the resistor 2 does not return to the initial setting resistance, that is, a melting temperature within a range of 80 ° C to 110 ° C. The resistor 2 is a resistor obtained by impregnating a cotton woven fabric with a carbon-based resistance solution in which flexible carbon particles and a resin are mixed with a solvent and then drying the resultant.
炭素系抵抗体 2は、 8 0 °C~ 1 1 0 °C以内の異常温度で局部でも初期設定 抵抗は変化する。 それ以上の異常温度になると、 劣化すると共に炭化し、 電気的にショ一トする。  The initial resistance of the carbon-based resistor 2 changes locally even at an abnormal temperature within the range of 80 ° C to 110 ° C. If the temperature rises above this level, it deteriorates and carbonizes, causing an electrical short.
