以上説明したように本発明に係る面状発熱体及び床暖房パネルによれば、発熱部がメッシュ状に形成され、かつ、電極線と交差する方向に延びる少なくとも２本の電源線と電極線とを安全保護回路を介して接続すると共に、電源線が、発熱部の縁部に位置する箇所に設けられた電源コネクタ部に接続されていることにより、新設あるいは既設の床を何ら改造する必要がないので、フロアーパネルの強度を確保することができると共に、面状発熱体を隣接させて設置したとき、これら隣接する面状発熱体の電源線を電源コネクタ部を介して接続することができるので、面状発熱体の設置を簡単に行える。   As described above, according to the planar heating element and the floor heating panel according to the present invention, the heating part is formed in a mesh shape, and at least two power lines and electrode lines extending in a direction intersecting with the electrode lines.

In addition, it is easy to install the planar heating element.

以下、本発明に係る面状発熱体及び床暖房の一例を添付図面に基づいて詳述する。   Hereinafter, an example of the planar heating element and floor heating according to the present invention will be described in detail with reference to the accompanying drawings.

図１及び図２は本発明に係る面状発熱体の一例を示す図である。図３は本発明に係る床暖房パネルの一例を示す図である。本発明に係る面状発熱体は、図１及び図２に示すように、所定間隔を空けて設置させた複数の電極線６と、これら電極線６間をつなぐシート状のＰＴＣ特性を有する発熱部３とを含むものである。この本発明に係る面状発熱体１は、発熱部３がメッシュ状に形成され、かつ、電極線６と交差する方向に延びる少なくとも２本の電源線７を設け、この各電源線７と電極線６とを安全保護回路１１を介して接続すると共に、電源線７が、発熱部３の縁部に位置する箇所に設けられた電源コネクタ部８に接続されていることに特徴がある。   1 and 2 are views showing an example of a planar heating element according to the present invention. FIG. 3 is a view showing an example of a floor heating panel according to the present invention. As shown in FIGS. 1 and 2, the planar heating element according to the present invention has a plurality of electrode wires 6 installed at a predetermined interval and a sheet-like PTC characteristic that connects these electrode wires 6. Part 3 is included. The planar heating element 1 according to the present invention is provided with at least two power lines 7 in which the heat generating portion 3 is formed in a mesh shape and extends in a direction intersecting with the electrode lines 6. The wire 6 is connected through the safety protection circuit 11, and the power supply line 7 is characterized in that it is connected to a power supply connector portion 8 provided at a position located at the edge of the heat generating portion 3.

面状発熱体１は、その形状は特に限定されないが、図１〜図３に示すように、例えば、矩形状等に形成されていることが好ましい。この面状発熱体１は、例えば、制震遮音材２（断熱遮音性に優れたクッション材）とフロアーパネル（フロアー材ということもある。）４との間に設けられて、床暖房パネル２０が構成されるが、制震遮音材２及びフロアーパネル４の枚数は特に限定されず、１枚でも２枚以上でもよく、例えば、各１枚である。この場合、面状発熱体１は、１枚の制震遮音材２と１枚のフロアーパネル４との間に挟まれて重ね合わされ、これら制震遮音材２及びフロアーパネル４を面状発熱体１を介して互いに接着して一体化することにより、可撓性を有する一枚の床暖房パネル２０が構成される。すなわち、制震遮音材２とフロアーパネル４とは、面状発熱体１を介して接着剤により接着される。この接着剤としては、制震遮音材２とフロアーパネル４とを接着し得るものであれば特に限定されず、例えば、コニシ株式会社製のボンド（製品番号：ＫＶ９２８Ｃ）等が挙げられる。なお、図１及び図２は本発明に係る面状発熱体の構成がわかり易いようにフロアーパネルを省略してある。   The shape of the planar heating element 1 is not particularly limited, but is preferably formed in, for example, a rectangular shape as shown in FIGS. The planar heating element 1 is provided, for example, between a vibration control and sound insulation material 2 (a cushion material having excellent heat insulation sound insulation) and a floor panel (sometimes referred to as a floor material) 4, and a floor heating panel 20. However, the number of the damping sound insulating material 2 and the floor panel 4 is not particularly limited, and may be one or two or more, for example, one each. In this case, the sheet heating element 1 is sandwiched between and superposed on one sheet of the damping sound insulating material 2 and one floor panel 4, and the sheet heating element 2 and the floor panel 4 are joined to the sheet heating element. A single floor heating panel 20 having flexibility is configured by bonding and integrating with each other via 1. That is, the vibration control and sound insulating material 2 and the floor panel 4 are bonded by the adhesive via the sheet heating element 1. The adhesive is not particularly limited as long as it can bond the vibration control and sound insulating material 2 and the floor panel 4, and examples thereof include a bond (product number: KV928C) manufactured by Konishi Co., Ltd. In FIGS. 1 and 2, the floor panel is omitted so that the configuration of the planar heating element according to the present invention can be easily understood.

制震遮音材２は、特に限定されず、例えば、従来から使用されている遮音等級LL-45以上の遮音材、オレフィン系樹脂制振マット等を使用することが望ましい。フロアーパネル４は、特に限定されず、面状発熱体に一般に用いられるもの等が挙げられ、例えば、市販されている南海アートフロアーのような床暖房対応品、松下電工株式会社製の商品名：オーマイティフロアー等を使用し、厚さ１２ｍｍ程度が望ましいが、この厚さのものに限定されない。   The vibration control material 2 is not particularly limited, and for example, it is desirable to use a sound insulation material having a sound insulation rating of LL-45 or higher, an olefin-based resin vibration control mat, or the like that has been conventionally used. The floor panel 4 is not particularly limited, and examples thereof include those generally used for planar heating elements. For example, a floor heating compatible product such as a commercially available Nankai art floor, a product name manufactured by Matsushita Electric Works, Ltd .: An ohmicity floor or the like is used and a thickness of about 12 mm is desirable, but the thickness is not limited to this.

面状発熱体１を構成する発熱部３は、基布の形状に特徴があり、この基布は、縦糸と横糸とがそれぞれ１ｍｍ程度の間隔で織られたメッシュ状に形成されている。縦糸及び横糸としては、例えば、綿糸（♯２０番手）等が挙げられる。これら縦糸及び横糸を、例えば、ドレーパー織機等で織ることによりメッシュ状の基布が形成される。   The heat generating portion 3 constituting the planar heating element 1 is characterized by the shape of the base fabric, and this base fabric is formed in a mesh shape in which warp yarns and weft yarns are woven at intervals of about 1 mm. Examples of the warp and weft include cotton yarn (# 20). A mesh-like base fabric is formed by weaving these warp yarns and weft yarns with, for example, a draper loom.

この基布に、発熱部材であるカーボンインク等の水性インクであるＰＴＣ導電性塗料を含浸させた上で、乾燥、加熱加工して作成したものが発熱部３である。この発熱部３は、例えば、幅（ｈ１）２８０ｍｍ、長さ（ｈ２）８９０ｍｍ、厚さ０．５ｍｍで形成されている。このように、発熱部３は、無公害の水性インクを用いているので、地球に優しいものである。また、発熱部３は、ＰＴＣ特性を有するために、安全性が高く、しかも、大電流の通過時に電気抵抗が増して電流ひいては発熱量が減少する自己温度制御特性を示すことから、床暖房パネル２０の面状発熱体１を構成するものとして最も好ましいものである。この面状発熱体１を用いることにより、面状発熱体１の温度が短絡等の事故のない場合、実用上又は安全上の上限値を超える温度にまで上昇する危険はなくなり、ニクロム線を使ったシート状ヒーターと違って、複雑な加熱防止機構が不要となる利点を有することになる。また、発熱部３がメッシュ状に形成されていることで、制震遮音材２とフロアーパネル４との間に発熱部３が接着される際に、発熱部３のメッシュの開口部を介して制震遮音材２とフロアーパネル４とが直接接着されるために、発熱部３に強度的な影響を与えることなく制震遮音材２とフロアーパネル４とを一体化することで面状発熱体１の耐久性を大幅に向上させることができる。   The heat generating portion 3 is formed by impregnating the base fabric with a PTC conductive paint, which is a water-based ink such as carbon ink, which is a heat generating member, followed by drying and heat processing. The heat generating part 3 is formed with, for example, a width (h1) of 280 mm, a length (h2) of 890 mm, and a thickness of 0.5 mm. Thus, since the heat generating part 3 uses non-polluting water-based ink, it is friendly to the earth. Moreover, since the heat generating part 3 has PTC characteristics, it has high safety, and further exhibits a self-temperature control characteristic in which electric resistance increases when a large current passes and current and thus heat generation decreases. It is most preferable as a constituent of the 20 sheet heating elements 1. By using this sheet heating element 1, when there is no accident such as a short circuit, there is no danger that the sheet heating element 1 will rise to a temperature exceeding the practical or safety upper limit value. Unlike the sheet heater, there is an advantage that a complicated heating prevention mechanism is unnecessary. Further, since the heat generating portion 3 is formed in a mesh shape, when the heat generating portion 3 is bonded between the vibration control and sound insulating material 2 and the floor panel 4, the heat generating portion 3 passes through the mesh opening of the heat generating portion 3. Since the vibration control sound insulating material 2 and the floor panel 4 are directly bonded, the surface heat generating element is obtained by integrating the vibration control sound insulating material 2 and the floor panel 4 without exerting a strong influence on the heat generating portion 3. 1 can be greatly improved in durability.

また、面状発熱体１には、発熱部３を通電により発熱させる面状の電極線６が例えば面状発熱体１の長手方向に延びて設けられている。電極線６は、特に限定されず、面状発熱体１の電極として一般的に用いられるもの等が挙げられる。電極線６は、所定間隔を空けて複数設置されている。電極線６の個数は、発熱部３の大きさ等に応じて任意に設定されるが、例えば、３つである。すなわち、発熱部３の両側部に第１電極線６ａがそれぞれ設けられていると共に、これら第１電極線６ａと平行であって発熱部３の幅方向の略中央部に延びる第２電極線６ｂが設けられている。   Further, the planar heating element 1 is provided with a planar electrode wire 6 that generates heat when the heating unit 3 is energized, for example, extending in the longitudinal direction of the planar heating element 1. The electrode wire 6 is not particularly limited, and examples thereof include those generally used as an electrode of the planar heating element 1. A plurality of electrode wires 6 are installed at a predetermined interval. The number of the electrode wires 6 is arbitrarily set according to the size of the heat generating portion 3 or the like, and is, for example, three. That is, the first electrode lines 6a are respectively provided on both sides of the heat generating portion 3, and the second electrode lines 6b extending in parallel with the first electrode lines 6a and substantially in the center of the heat generating portion 3 in the width direction. Is provided.

また、発熱部３上には、電極線６と交差する方向（面状発熱体１の幅方向）に延びる少なくとも２本の電源線７が設けられている。これらの電源線７は、電源に接続されるものである。電源線７は、例えば、ラミネート加工に形成された２本の線からなる。電源線７の位置は、特に限定されず、例えば、発熱部３の一方の端部からその長さ（長手方向の長さ）の約１／４の位置、具体的には、一方の端部から所望の長さ（ｈ３）例えば２２３ｍｍ離間した位置等である。２本のうちの一方の電源線７に、例えば、２つの第１電極線６ａが接続されると共に、残りの電源線７に、第２電極線６ｂが接続される。これら電源線７と電極線６ａ、６ｂとの間には、それぞれ安全保護回路１１が設けられていることが好ましい。   Further, on the heat generating portion 3, at least two power supply lines 7 extending in a direction intersecting with the electrode lines 6 (width direction of the planar heating element 1) are provided. These power lines 7 are connected to a power source. The power supply line 7 is composed of, for example, two lines formed by laminating. The position of the power supply line 7 is not particularly limited, and is, for example, a position that is about ¼ of the length (length in the longitudinal direction) from one end of the heat generating portion 3, specifically, one end. To a desired length (h3), for example, a position separated by 223 mm. For example, two first electrode lines 6 a are connected to one of the two power lines 7, and the second electrode line 6 b is connected to the remaining power lines 7. A safety protection circuit 11 is preferably provided between the power supply line 7 and the electrode lines 6a and 6b.

安全保護回路１１は、特に限定されないが、例えば、ヒューズ１２等であることが好ましい。ヒューズ１２は、図４に示すように、例えば、両端部に設けた幅広の端子部１２ａに鳩目取付用の透孔１２ｂを設け、各端子部１２ａ間に長手方向に伸びる長孔１２ｃを有する幅狭の溶断部１２ｄを一体的に設けたヒューズ本体１２ｅと、さらに各端子部１２ａの一部と溶断部１２ｄを貼着被覆した例えば雲母フィルム（商品名：マイカ粘着テープ）から成る耐火フィルム１２ｆとで構成されていることが好ましい。   The safety protection circuit 11 is not particularly limited, but is preferably a fuse 12 or the like, for example. As shown in FIG. 4, the fuse 12 has, for example, a wide terminal portion 12a provided at both end portions provided with a through hole 12b for eyelet attachment, and a long hole 12c extending in the longitudinal direction between the terminal portions 12a. A fuse body 12e integrally provided with a narrow fusing part 12d, and a fireproof film 12f made of, for example, a mica film (trade name: mica adhesive tape) in which a part of each terminal part 12a and a fusing part 12d are adhered and coated; It is preferable that it is comprised.

ヒューズ本体１２ｅの材料としては、例えば、洋白（鉛、錫、銅の合金）を用いるが、これに限定されず、必要に応じて燐青銅、その他の銅合金、鉛、錫、アルミニウム等を単体で或は適宜組み合わせて合金として用いてもよい。耐火フィルム１２ｆは、雲母フィルム（商品名：マイカ粘着テープ）が好適であるが、これ以外に耐熱温度５００℃以上の耐熱フィルムやテープ等を用いることができる。   As the material of the fuse body 12e, for example, white (lead, tin, copper alloy) is used, but is not limited thereto, and phosphor bronze, other copper alloys, lead, tin, aluminum, etc. are used as necessary. They may be used alone or in an appropriate combination as an alloy. The fireproof film 12f is preferably a mica film (trade name: mica adhesive tape), but other than this, a heat resistant film or tape having a heat resistant temperature of 500 ° C. or higher can be used.

また、電源線７の両端部には、図１及び図２に示すように、電源コネクタ部８がそれぞれ設けられている。電源コネクタ部８は、電源線７の両端部に接続されるメス型コネクタ９と、メス型コネクタ９に接続される両オス型コネクタ１０とで構成されていることが好ましい。   Moreover, as shown in FIG.1 and FIG.2, the power supply connector part 8 is provided in the both ends of the power supply line 7, respectively. The power connector 8 is preferably composed of a female connector 9 connected to both ends of the power line 7 and a male connector 10 connected to the female connector 9.

The female connector 9 has a connection surface positioned on the inner side of the long side portion of the planar heating element 1 and approximately the same dimension as the half of the length (h7) of the housing of the male connectors 10. It is preferable to arrange so as to be a place. That is, the length (h4) between the end portions of the long side portion of the planar heating element 1 is the length between the female connectors 9 (h5) and the length of the housing of both male connectors 10 (h7). The dimension is almost the same as the size added. As a result, when the planar heating element 1 is laid on, for example, the vibration-damping sound insulating material 2, and the female connectors 9 of the two adjacent planar heating elements 1 are connected via the male connectors 10, these The long side portions of the two adjacent sheet heating elements 1 are in contact with or close to each other.

なお、メス型コネクタ９は、面状発熱体１の長辺部に設けたが、これに限定されず、例えば、短辺部にそれぞれ設けるようにしてもよいし、短辺部と長辺部との両方に１個ずつ設けるようにてもよいし、また、メス型コネクタの個数も特に限定されず、３個以上設けるようにしてもよく、例えば、４つの辺部（短辺部及び長辺部）にそれぞれ１個ずつ設けるようにしてもよいし、１つの短辺部や長辺部に２個以上設けるようにしてもよい。   In addition, although the female connector 9 was provided in the long side part of the planar heating element 1, it is not limited to this, For example, you may make it each provide in a short side part, a short side part and a long side part The number of female connectors is not particularly limited, and three or more female connectors may be provided. For example, four side portions (short side portion and long side portion) may be provided. One piece may be provided on each side portion, or two or more pieces may be provided on one short side portion or long side portion.

これらメス型コネクタ９、電源線７及びヒューズ１２が、例えば、ポリプロピレンフィルム、ＰＥＴフィルム等の絶縁フィルム１５を介して発熱部３上に設けられて、発熱部３から絶縁されていることが好ましい。これらメス型コネクタ９、電源線７、ヒューズ１２及び発熱部３が１枚の制震遮音材２と１枚のフロアーパネル４とで挟んでこれら制震遮音材２とフロアーパネル４を互いに接着してシート状の面状発熱体１が形成される。その制震遮音材２とフロアーパネル４の接着方法としては、各制震遮音材２とフロアーパネル４を発熱部３より少し大きい矩形状に形成して、発熱部３の外側の制震遮音材２とフロアーパネル４との各縁部（メス型コネクタ９を除く縁部）を例えば耐熱性の両面テープ等で接着するようにしてもよい。   It is preferable that the female connector 9, the power supply line 7, and the fuse 12 are provided on the heat generating part 3 via an insulating film 15 such as a polypropylene film or a PET film and insulated from the heat generating part 3. These female connector 9, power supply line 7, fuse 12 and heat generating part 3 are sandwiched between a single vibration control sound insulating material 2 and a single floor panel 4, and these vibration control sound insulating material 2 and the floor panel 4 are bonded to each other. Thus, a sheet-like planar heating element 1 is formed. As a method of bonding the vibration control sound insulating material 2 and the floor panel 4, the vibration control sound insulating material 2 and the floor panel 4 are formed in a rectangular shape slightly larger than the heat generating portion 3, and the vibration control sound insulating material outside the heat generating portion 3 is formed. Each edge part (edge part excluding the female connector 9) of 2 and the floor panel 4 may be bonded with, for example, a heat-resistant double-sided tape.

次に本発明に係る面状発熱体１をスラブ２１上に設置する場合について説明する。まず、制震遮音材２及びフロアーパネル４を面状発熱体１を介して互いに接着して一体化させた、例えば、矩形平板状の床暖房パネル２０を形成する。次に。コンクリートスラブ等のスラブ２１上に、図３に示すように、床暖房パネル２０を敷設する。この場合、例えば、複数の床暖房パネル２０を当接又は近接させつつ面状発熱体１の両オス型コネクタ１０を介して電気的に接続しながら並設させる。これにより、スラブ２１上の全体又は所望の箇所に面状発熱体１を有する床暖房パネル２０が敷設される。これら床暖房パネル２０上に必要に応じてカーペット２９等を敷設するようにしてもよい。   Next, the case where the planar heating element 1 which concerns on this invention is installed on the slab 21 is demonstrated. First, the floor heating panel 20 having, for example, a rectangular flat plate shape is formed by bonding the vibration control sound insulating material 2 and the floor panel 4 to each other via the planar heating element 1 and integrating them. next. As shown in FIG. 3, a floor heating panel 20 is laid on a slab 21 such as a concrete slab. In this case, for example, the plurality of floor heating panels 20 are juxtaposed while being electrically connected via both male connectors 10 of the planar heating element 1 while abutting or approaching the floor heating panels 20. Thereby, the floor heating panel 20 having the sheet heating element 1 is laid on the entire slab 21 or at a desired location. A carpet 29 or the like may be laid on the floor heating panel 20 as necessary.

したがって、コンクリートのスラブ２１、制震遮音材２、フロアーパネル４等を傷つけたり、加工したりして改造する必要がないので、フロアーパネル４の強度を確保することができると共に、単に面状発熱体１を有する床暖房パネル２０を敷設して両オス型コネクタ１０を介して別の床暖房パネル２０の面状発熱体１等に接続させるだけでよいので、面状発熱体１及び床暖房パネル２０を簡単にしかも安価に設置することが可能となる。また、複数の床暖房パネル２０を敷設することから、床暖房パネル２０を設置する部屋等が狭くても広くても現場ですぐに対応できるために、部屋の広さに応じて予め工場で製造しなくても現場で対応することができるので、汎用性に優れていると共に工業的価値が高いものである。   Therefore, since it is not necessary to modify or modify the concrete slab 21, the vibration control and sound insulation material 2, the floor panel 4, etc., the strength of the floor panel 4 can be ensured and the surface heat generation is simply performed. Since the floor heating panel 20 having the body 1 is laid and connected to the sheet heating element 1 or the like of another floor heating panel 20 via the both male connectors 10, the sheet heating element 1 and the floor heating panel are required. 20 can be easily and inexpensively installed. In addition, since a plurality of floor heating panels 20 are laid, the floor heating panel 20 can be manufactured in a factory in advance according to the size of the room so that it can be immediately handled on the spot even if the room where the floor heating panel 20 is installed is small or wide. Even if it is not possible, it can be handled on site, so it has excellent versatility and high industrial value.

また、メス型コネクタ９は、面状発熱体１の長辺部の端部より両オス型コネクタ１０の筐体の略半分の長さと略同じ寸法内側に位置されることにより、複数の面状発熱体１を設置したときに、隣接する２つの面状発熱体１の長辺部が互いに当接又は近接する。その結果、複数の面状発熱体１との間に大きな溝が形成されることがないので、大きな凹凸がなく面状発熱体１及び床暖房パネル２０を設置することができる。   In addition, the female connector 9 is positioned on the inner side of substantially the same length as the half of the casing of the male connector 10 from the end of the long side portion of the planar heating element 1, thereby providing a plurality of planar shapes. When the heating element 1 is installed, the long side portions of the two adjacent planar heating elements 1 are in contact with or close to each other. As a result, since a large groove is not formed between the plurality of sheet heating elements 1, the sheet heating element 1 and the floor heating panel 20 can be installed without large unevenness.

以上説明したように本発明に係る面状発熱体は、発熱部がメッシュ状に形成され、かつ、電極線と交差する方向に延びる少なくとも２本の電源線と電極線とを安全保護回路を介して接続すると共に、電源線が、発熱部の縁部に位置する箇所に設けられた電源コネクタ部に接続されていることにより、新設あるいは既設の床を何ら改造する必要がないので、フロアーパネルの強度を確保することができると共に、面状発熱体を隣接させて設置したとき、これら隣接する面状発熱体の電源線を電源コネクタ部を介して接続することができるので、面状発熱体の設置を簡単にしかも安価に設置を行えることから、特に３畳間から２０畳間程度までの一般家庭用住宅の各部屋を床暖房するのに最適なものである。   As described above, in the planar heating element according to the present invention, the heat generating portion is formed in a mesh shape, and at least two power lines and electrode lines extending in a direction intersecting the electrode lines are connected via a safety protection circuit. And the power line is connected to the power connector at the edge of the heat generating part, so there is no need to modify the new or existing floor. In addition to ensuring the strength, when the planar heating elements are installed adjacent to each other, the power wires of these adjacent planar heating elements can be connected via the power connector portion. Since installation can be performed easily and inexpensively, it is particularly suitable for floor heating of each room of a general home from about 3 tatami mats to about 20 tatami mats.
