発熱装置に使用される面状発熱体に関するものである。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a planar heating element used for household electric appliances such as electric mats and electric blankets, and various heating apparatuses such as floor heating and snow melting equipment.

うにしている。2. Description of the Related Art A conventional planar heating element is disclosed in, for example,
As shown in -142154, a printing electrode made of silver paste or the like is provided in the vicinity of opposite sides of a heating element which is formed by processing a carbon fiber into a sheet shape so as to be able to conduct electricity,
An electric wire for conduction is led out from the printed electrode, and the entire surface is covered with a water-resistant and waterproof film.

するようになる。However, in the conventional sheet heating element, a printing electrode made of silver paste or the like is provided near both sides of the sheet heating element facing each other. If the sheet-like heating element on the outer surface rubs against the external member to which it is attached and the waterproof film breaks, the printed electrode also breaks in a relatively short time.

比較的硬質に形成する必要があるため、形成された面状
発熱体は少なくとも当該部分において可撓性が低下し、
例えば、暖房用毛布等に使用する場合には、上記の可撓
性が低下した部分において違和感が生じる。[0004] Further, since the portion on which the printed electrode is provided must be flat and relatively hard, the flexibility of the formed planar heating element is reduced at least in the portion.
For example, when used for a heating blanket or the like, a sense of incongruity occurs in the portion where the flexibility is reduced.

ボン繊維の温度上昇は電流値に比例しておらず、或る電
流値を超えると急激に温度上昇が起こるため温度制御が
難しいといった問題がある。Further, since a portion formed by processing the carbon fiber into a sheet shape is configured to be energized, and this portion is used as a heat generating portion, not only the flexibility is low but the cost is increased, but also the temperature rise of the carbon fiber is reduced. There is a problem that the temperature is not proportional to the current value, and if the current value exceeds a certain current value, the temperature rises sharply, so that the temperature control is difficult.
【０００６】本発明は、上記のような問題点を解決せん
とするもので、その目的は電極線が面状発熱素子の面外

で、温度制御が容易な面状発熱体を提供するにある。SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and has as its object that the electrode wires do not protrude out of the surface of the planar heating element, are flexible, and have a relatively low cost. Accordingly, it is an object of the present invention to provide a planar heating element that can easily control the temperature.

A plurality of conductive electrode strips having a property are arranged at predetermined intervals, woven together with the fiber yarns, and a carbon-based conductive material is applied to the woven fabric thus woven by coating or impregnation. The upper and lower surfaces of these carbon-based conductive materials are covered with an electrically insulating coating material, and electrode terminals are attached to the ends of the respective electrode strips.

温度制御が容易となる。As described above, since the conductive electrode strip having a narrow width and flexibility is woven together with the fiber yarn, the electrode strip does not protrude to the outside from the woven fabric serving as the heat generating portion. It does not rub against the member and break before other parts. In addition, since carbon-based conductive materials are attached to the woven fabric and these are heated by energization, the temperature can be easily controlled at lower cost than in the conventional example using carbon fibers.

A plurality of narrow conductive electrode strips are arranged at predetermined intervals as a part of the woven fabric, woven together with the fiber yarns, and the upper and lower surfaces of a woven fabric formed by woven these fiber yarns and the electrode strips are electrically insulated. Each of the electrode strips is covered with a conductive coating material, and an electrode terminal is attached to an end of each of the electrode strips.

An extremely flexible planar heating element can be obtained, and the temperature can be easily controlled at low cost as in the above case.

Or it is braiding a vertical fiber wire to the conductive wire group.
【００１２】これにより、電極となる導電線群が縦繊維

比較して可撓性は一段と向上する。[0012] Thus, since the conductive wire group serving as the electrode is braided together with the warp fiber yarn or the weft fiber yarn, the flexibility is further improved as compared with the above case.

When it is 7 mm and is disposed at an interval of 40 mm to 80 mm with respect to the woven fabric, desired heat generation can be obtained with a relatively low current.

In many cases, even if a part of the conductive wire group is cut for some reason, the other part generates heat, so that the function is not impaired as a whole.

しないことである。。First, in the above-described embodiment, five copper wires 4 having substantially the same thickness as the cotton yarn 5 are grouped into a group 4a. However, the number is not limited to five and may be plural. The number may be four, preferably four to eight.
Thereby, even if one of them is cut off for some reason, the other remaining copper wires can function as electrodes. Also, instead of the electrode copper wire group 4a, a highly flexible band having a width substantially equal to that of the group of electrode copper wires can be used. In this case, the band is braided as a single warp with a weft. It is needless to say that a wire or band having another conductivity can be used instead of the copper wire for the electrode. It is needless to say that a fine stranded copper wire having a similar cross section to the illustrated copper wire can be used as the electrode copper wire 4. Further, in the above embodiment of the present invention, the woven fabric is formed by arranging the electrode copper wires 4 as vertical lines, but unlike this, it is possible to arrange these as horizontal lines to form the woven fabric. That is, detailed description is not required. .

る。The width of the electrode strip composed of the electrode copper wire group or the electrode strip is preferably 3 to 7 mm, and is arranged at an interval of 40 to 80 mm with respect to the woven fabric. As a result, the amount of current flowing through the electrode strip can be increased, and the width of the carbon-based conductive material sandwiched between the adjacent electrodes can be made relatively narrow. Efficiency can be improved.

In any case, the connection is made such that adjacent electrode copper wire groups 4a are different electrodes.

である。It is also preferable that the cotton yarn constituting the woven fabric is preliminarily impregnated with a carbon-based conductive material so as to be attached thereto, and the woven fabric is woven as described above using the thus impregnated cotton yarn. It is. In this case, the step of impregnating the carbon-based conductive material after weaving the woven fabric as described above is unnecessary, but if necessary, the step of impregnating can be supplemented. Needless to say, other fiber yarns can be used instead of the cotton yarns.

簡単に制御することができる。As is apparent from the above description, in the planar heating element of the present invention, the conductive electrode strip (conductive wire group, conductive strip) is braided together with the fiber yarn to form a woven fabric. Therefore, the electrode strip does not protrude to the outside from the woven fabric serving as the heat generating portion, and does not rub against an external member and break before the other parts. Moreover, since the electrode band occupies only a small portion of the whole woven fabric and the fiber yarn occupies most of the woven fabric, the sheet heating element of the present invention has excellent flexibility like a woven fabric, and a curvature. It can be arranged along a curved portion having a small radius. In addition, since carbon-based conductive materials are attached to the woven fabric and these are heated by energization, the temperature can be easily controlled at lower cost than in the conventional example using carbon fibers. The time required to reach the predetermined temperature and the predetermined heat generation temperature can be relatively easily controlled by the amount of the carbon-based conductive material attached and / or the woven density of the woven fabric.

場合と同様に安価にして温度制御が容易となる。When a woven fabric is formed by using a fiber yarn previously impregnated with a carbon-based conductive material, a planar heating element having even more excellent flexibility can be obtained. As in the case, the temperature is reduced and the temperature control becomes easy.

からなる織布と同程度のものとなる。When a conductive wire group having the same diameter as the warp or weft yarn is used as the conductive electrode strip, the conductive wire group serving as an electrode may be a warp or weft fiber. Because it is braided with the yarn, its flexibility is comparable to that of a woven fabric made of ordinary fiber yarn.
