線を備えた面状発熱体に関する。[Detailed description of the invention] (Industrial application field) The invention is a planar heating element used for electric carpets, etc.
Specifically, of the sheet heating element, the heating area is divided into two,
A sheet-like heating element having a heat-sensitive heating wire that can selectively select the heat generation portion and has a heat generation function having a heater electrode and a sensor electrode via a heat-sensitive resin material and a sensor function for temperature detection integrated with each other. About.
（従来の技術） 電気カーペット等の暖房器具は低温輻射と座臥する人
への接触伝熱とで暖房感を得るものであり、面積が広い
ことが必要であるが、近年、省エネルギーの観点から使
用する人数に応じて暖房面積を切り換え、少人数の場合
は小さな面積で使用する使われ方が普及し始めている。
この背景としては、省エネルギー以外に、電気カーペッ

とも多く、主暖房器具としての輻射暖房感や室温を上昇
させる能力をあまり問題としない使われ方も多いためと
思われる。(Prior art) Heating appliances such as electric carpets provide a feeling of heating by low-temperature radiation and contact heat transfer to a person who sits down, and it is necessary to have a large area. The heating area is switched according to the number of users, and when the number of people is small, the use of a small area is beginning to spread.
Behind this, besides energy savings, electric carpets are often used with other heaters and, if used, oil stoves, etc., and the use of radiant heating as the main heating device and the ability to raise the room temperature does not matter much. It seems that we are many.
従って、電気カーペット等の暖房器具に要求されてい

る。Therefore, as a function required for a heating appliance such as an electric carpet, when used alone, it is possible to raise the room temperature from heating that emphasizes contact heat transfer, which can heat only a portion where the person is sitting. It is required that the heating method can be freely selected up to heating that can heat a wide area as in the case of using by a large number of people.
また、近年ヒータの温度を直接温度検知できるので、
安全性が高く、かつヒータ線以外にセンサー線を有する
タイプのものに比べて、ヒータ線とセンサー線とが一体

楽である等の理由により、発熱機能と温度検知機能とを
一体とした面状発熱体が実用化され始めている。Also, since the temperature of the heater can be directly detected in recent years,
Since the heater wire and the sensor wire are integrated as compared with the type having high safety and having a sensor wire in addition to the heater wire, the length of the wire may be short and the wiring work is easy. For these reasons, a planar heating element integrating a heat generation function and a temperature detection function has begun to be put into practical use.
この面状発熱体は第５図に示す感熱発熱線Ｈを第６図
に示す均熱シートＣに取り付けた構成となっている。This planar heating element has a configuration in which a heat-sensitive heating wire H shown in FIG. 5 is attached to a heat equalizing sheet C shown in FIG.

After extruding and coating a heat-sensitive resin layer 12 which is a heat-sensitive resin material kneaded with an additive such as a quaternary ammonium salt, a temperature detection electrode 13 as a sensor electrode made of a copper alloy or the like is spirally wound, and further made of a polyester tape or the like. After providing a separating layer 14 and covering an insulating layer 15 such as a soft PVC, a heat bonding layer 16 such as a low-density polyethylene
The heat-generating heating wire H provided with the heat-generating sheet H is heat-sealed to the soaking sheet C shown in FIG.

It is manufactured by a method in which the above-mentioned pins are integrated into the circuit board by retracting the pins at the same time as hot pressing.

精度が高い等の理由により実用化に適している。As a method of controlling the temperature of this type of planar heating element, the heat-sensitive heating wire H also serves as one of the temperature detection electrodes, so it is necessary to devise a method of discriminating the sensor signal, and forcibly stop the heat generation to check the temperature. (See, for example, JP-A-62-115685) and a method of performing temperature control using the zero-volt cycle of the heating wire (see, for example, JP-A-62-256114).
There is a method using a sensor voltage (Japanese Unexamined Patent Publication No.
However, the temperature control can be easily performed and the accuracy is high, which is suitable for practical use.

い。In the case of this temperature control system, the connection side Fa of the heat-sensitive heating wire Ha that connects the heater electrode 4a and the sensor electrode 6a at one end, and the heat-sensitive heating wire Hb that connects the heater electrode 4b and the sensor electrode 6b at one end.
On the connection side Fb, the control current flowing through the thermosensitive resin material 5 is small.

As seen from the above, a pattern is formed such that the connection side Fa and the non-connection side Ga of the heat-sensitive heating wire Ha are arranged substantially in parallel on the a-block side, and the connection side Fb is not connected to the connection side Fb of the heat-sensitive heating wire Hb on the b-block side. Connection side
A pattern is formed so that Ga and Ga are arranged almost in parallel, so that a uniform temperature control operation can be performed.

９図に示す様に、各感熱発熱線Ha,Hbはほぼ均一ピッチ

態が発生しても、部分断熱部の熱量供給は他の部分と同
じ様に行われる。(Problems to be Solved by the Invention) By the way, in such a conventional planar heating element, as shown in FIG. 9, the heat-sensitive heating wires Ha and Hb are wired at a substantially uniform pitch. Even if a partial insulation state occurs due to the placement of a seat or the like, the supply of heat to the partial insulation portion is performed in the same manner as the other portions.

温度検知は、ａブロック側とｂブロック側とに分かれて
しまう。When a Zamadan or the like is placed on the boundary line E of the divided heating block and a partial heat insulation state occurs, the heat supply of the partial heat insulation portion is performed in the same manner as the other parts, but the temperature detection near the boundary line E is performed. Is divided into a block side and b block side.
従って、センサー電極6aと6bに流れる制御電流の合計
は座蒲団等が例えばａブロック側にだけ置かれた場合と
同じあるが、ａブロック側ではセンサー電極6aの制御電
流だけであるので、温度制御動作が行われない。ｂブロ
ック側も同様である。Therefore, the sum of the control currents flowing through the sensor electrodes 6a and 6b is the same as when the Zamadan or the like is placed only on the a-block side, but the control current of the sensor electrode 6a is only on the a-block side. Is not done. The same applies to the b-block side.
そこで、ａブロック側だけ、またはｂブロック側だけ
に比べるとセンサー検知が分散されたかたちとなり、境
界線Ｅ近傍での部分断熱温度上昇が大きくなるという課
題があった。Therefore, there is a problem that the sensor detection is dispersed in comparison with only the a-block side or only the b-block side, and the partial adiabatic temperature rise near the boundary line E is large.
しかも部分断熱温度が大きくなるということは、低温
火傷の問題や感熱樹脂材５の特性の経時変化を発生させ
る等の傾向があり改善が望まれていた。In addition, an increase in the partial adiabatic temperature tends to cause a problem of a low-temperature burn and a change in characteristics of the heat-sensitive resin material 5 with time, and thus improvement has been desired.

したことに特徴を有している。Embodiment 2 FIG. 4 shows a second embodiment of the present invention. In this embodiment, one side of the boundary line E of the heating block is, for example, a heat-sensitive heating line.
It is characterized in that the connection side Fa and the non-connection side Ga of Ha are patterned so as to be arranged in parallel, and the non-connection side of the heat-sensitive heating wire is arranged near the boundary line E.

部分断熱温度の低減には有効である。In this manner, other than the connection in which both sides of the boundary line E are the connection sides Fa and Fb, the connection in which only one side is the non-connection side Ga or Gb,
It is effective for reducing the partial adiabatic temperature.
その理由は、境界線Ｅ近傍での部分断熱温度が高温に
なるのはA,Bブロック２チャンネルとも発熱する様に選
択されている場合であって、片側のみが発熱する様に切
り替えがされている場合は、部分断熱の熱量供給が不足
し、蓄熱しないので、温度上昇がもともと低いことによ
る。もちろん断熱面積が大きくなると熱量供給は多くな
るが、その場合には、断熱部の感熱発熱線Ｈの比率も増
すので、低温で制御が行われる。The reason is that the partial adiabatic temperature near the boundary line E becomes high when the two channels A and B are selected so as to generate heat, and switching is performed so that only one side generates heat. In this case, the supply of heat for the partial insulation is insufficient and the heat is not stored, so the temperature rise is originally low. Of course, as the heat insulating area increases, the amount of heat supply increases, but in that case, the ratio of the heat-sensitive heat generating wires H in the heat insulating portion also increases, so that the control is performed at a low temperature.
また、境界線Ｅ近傍での配線ピッチを他の部分に比べ
ていくぶん広くする等の方法と併用すればさらに効果的
である。Further, it is more effective if used together with a method such as making the wiring pitch near the boundary line E somewhat wider than other parts.

でもない。It goes without saying that, regardless of the type of the first embodiment or the type of the second embodiment, the effect of lowering the partial adiabatic temperature can be obtained as compared with the conventional example shown in FIG.
