Description
【０００１】[0001]
本考案は、電気加熱器具に備えられている電気ヒーターから発生する電磁波に 対する対策を施した電磁波抑制ヒーターに属する。 The present invention belongs to an electromagnetic wave suppression heater in which measures are taken against electromagnetic waves generated from an electric heater provided in an electric heating device.
【０００２】[0002]
従来、人体に最も近い位置で使用されている電気加熱器具の一例としては、電 気カーペットや電気毛布・敷布などの電気採暖器具がある。このような電気採暖 具では、使用面積が大きく、消費電力量も大きいものである。電気採暖具では、 例えば、電圧が１００Ｖ 周波数が５０〜６０Ｈｚ（低周波）であり、使用時に 発生する電磁波は電界よりも磁界成分が高いものである。このような磁界成分の シールドするには、透磁率の高いシールド方法が要求されている。 Conventionally, examples of electric heating appliances used closest to the human body include electric heating appliances such as electric carpets, electric blankets and bedsheets. Such an electric heater has a large use area and a large power consumption. In an electric warming device, for example, the voltage is 100 V, the frequency is 50 to 60 Hz (low frequency), and the electromagnetic wave generated during use has a higher magnetic field component than an electric field. In order to shield such a magnetic field component, a shield method having a high magnetic permeability is required.
【０００３】[0003]
上述した電気採暖具の磁界成分のシールドには、透磁率の高い金属板のような シールド板によって覆うことが最良の方法であるが、使用面積が大きく、かつ電 気ヒーターやこの電気ヒーターを所定位置に配置し覆っている平面状の基布など に柔軟性をもたせた状態で使用しなければならず、シールド板によるシールドは 採用できないという問題がある。 The best way to shield the magnetic field component of the electric warmer mentioned above is to cover it with a shield plate such as a metal plate with high magnetic permeability. It must be used with flexibility provided to the flat base cloth that is placed and covered at the position, and there is a problem that shielding by a shield plate cannot be adopted.
【０００４】 それ故に、本考案の課題は、簡便な構成によって電気器具から発生する電磁波 を減衰させ、電磁波を抑制する電磁波抑制ヒーターを提供することにある。[0004] Therefore, an object of the present invention is to provide an electromagnetic wave suppression heater that attenuates electromagnetic waves generated from an electric appliance with a simple configuration and suppresses the electromagnetic waves.
【０００５】[0005]
本考案によれば、絶縁性の巻芯と、該巻芯上に螺旋状に巻かれた一対の発熱導 体とを含み、前記一対の発熱導体は互いに所定間隔をもって前記巻芯上に巻かれ ており、前記一対の発熱導体は一端部のそれぞれから電流を流した際に、前記巻 芯上で隣り合う前記発熱導体に流れる電流が相互に逆方向となるよう前記一対の 発熱導体の他端を相互に接続した結線部を有していることを特徴とする電磁波抑 制ヒーターが得られる。 According to the present invention, there is provided an insulating core and a pair of heating conductors spirally wound on the core, wherein the pair of heating conductors are wound on the core at a predetermined interval from each other. The other end of the pair of heating conductors is configured such that, when current flows from each of the one end portions, currents flowing in the adjacent heating conductors on the winding core are in opposite directions to each other. And an electromagnetic wave suppression heater characterized in that it has a connection portion where the heaters are connected to each other.
【０００６】[0006]
本考案の電磁波抑制ヒーターにおいては、発熱導体を２本を並列に螺旋状に横 巻し、その一端部を接続して直列回路となし、他の一端部より電流を流した際に 、隣り合う発熱導体に流れる電流が相互に逆方向となり、発生する磁力線を打ち 消す。 In the electromagnetic wave suppression heater of the present invention, two heating conductors are spirally wound in parallel in a spiral shape, and one end thereof is connected to form a series circuit, and when current flows from the other end, they are adjacent to each other. The currents flowing through the heating conductors are in opposite directions, canceling out the generated magnetic lines of force.
【０００７】[0007]
図１は、本考案の電磁波抑制ヒーターの一実施の形態例を示している。図１を 参照して、電磁波抑制ヒーターは、ガラス糸もしくは樹脂糸などが束ねられて形 成されている絶縁性の巻芯１と、この巻芯１上に螺旋状に巻かれた一対の発熱導 体３，５とを含む。 FIG. 1 shows an embodiment of the electromagnetic wave suppression heater of the present invention. Referring to FIG. 1, the electromagnetic wave suppression heater includes an insulating core 1 formed by bundling a glass thread or a resin thread, and a pair of heat generating coils spirally wound on the core 1. Conductors 3 and 5 are included.
【０００８】 一対の発熱導体３，５は互いに所定間隔をもって巻芯１上に巻かれている。さ らに、一対の発熱導体３，５は一端部のそれぞれから電流を流した際に、巻芯１ 上で隣り合う発熱導体３，５に流れる電流が相互に逆方向となるように一対の発 熱導体３，５の他端を相互に接続した結線部７を有している。The pair of heat generating conductors 3 and 5 are wound on the core 1 at a predetermined interval from each other. Further, the pair of heat generating conductors 3 and 5 are arranged such that when current flows from each of the one end portions, the current flowing through the adjacent heat generating conductors 3 and 5 on the winding core 1 is opposite to each other. It has a connection portion 7 that connects the other ends of the heat generating conductors 3 and 5 to each other.
【０００９】 一対の発熱導体３，５の一端部は巻芯１から離れる方向へのびて状態で互いに 離れている。一対の発熱導体３，５の他端は巻芯１から離れる方向へのびた状態 で互いに近付く向きへのび先端の結線部７によって結線されている。One ends of the pair of heat generating conductors 3 and 5 are separated from each other while extending in a direction away from the core 1. The other ends of the pair of heat generating conductors 3 and 5 are connected to each other by a connection portion 7 at the leading end in a direction of approaching each other while extending in a direction away from the core 1.
【００１０】 本考案の電磁波抑制ヒーターでは、フレミングの左手の法則にしたがって、隣 り合う発熱導体３，５で電流の方向を対向さるせように、巻芯１上に一対の発熱 導体３，５が巻かれているので、図２に矢印によって示す電流が隣り合う発熱導 体３，５で交互に流れ、電流によって発生する磁力線が打ち消される。According to the electromagnetic wave suppression heater of the present invention, a pair of heating conductors 3, 5 are arranged on the winding core 1 in such a manner that adjacent heating conductors 3, 5 oppose each other according to Fleming's left-hand rule. The currents indicated by arrows in FIG. 2 flow alternately in the adjacent heating conductors 3 and 5, and the lines of magnetic force generated by the currents are cancelled.
【００１１】 上述した電磁波抑制ヒーターは、一対の発熱導体３，５が露出してる状態で使 用されるものであるが、一対の発熱導体３，５に絶縁処理を施して使用すること が可能である。この場合、ポリベンゾイミダゾールを溶液化した樹脂ワニス（Ｐ ＢＩワニス）を一対の発熱導体３，５に塗布して絶縁層を形成するか、ポリアミ ドエミド（ＰＡＩワニス）を一対の発熱導体３，５に塗布して絶縁層を形成する と絶縁性・耐熱性に優れたものとなる。そして、このような構成とすることによ って、電磁波を抑制し、かつ絶縁性・耐熱性に優れた電磁波抑制ヒーターが得ら れる。The above-described electromagnetic wave suppression heater is used in a state where the pair of heat generating conductors 3 and 5 are exposed, but it is possible to use the pair of heat generating conductors 3 and 5 after performing insulation treatment. It is. In this case, a resin varnish (PBI varnish) in which polybenzimidazole is made into a solution is applied to the pair of heating conductors 3 and 5 to form an insulating layer, or a polyamide amide (PAI varnish) is applied to the pair of heating conductors 3 and 5. When applied to the substrate to form an insulating layer, the insulating and heat resistance becomes excellent. With such a configuration, an electromagnetic wave suppression heater that suppresses electromagnetic waves and has excellent insulation and heat resistance can be obtained.
【００１２】 さらに、電気採暖具に用いる電磁波抑制ヒーターとしては、図１に示した電磁 波抑制ヒーター上にナイロンのような第１の樹脂層１１を被覆し、さらに第１の 樹脂層１１上にポリ塩化ビニルのような第２の樹脂層１３を被覆する。このよう な構成とすると、絶縁性・耐熱性に優れた電気採暖具が得られると同時に、電磁 波抑制ができるものとなる。Further, as the electromagnetic wave suppression heater used for the electric warming device, a first resin layer 11 such as nylon is coated on the electromagnetic wave suppression heater shown in FIG. 1, and further on the first resin layer 11. Cover a second resin layer 13 such as polyvinyl chloride. With such a configuration, an electric heater with excellent insulation and heat resistance can be obtained, and at the same time, electromagnetic waves can be suppressed.
【００１３】[0013]
以上、実施の形態例によって説明したように、本考案の電磁波抑制ヒーターの 構成によれば、発熱導体を２本並列に螺旋状に横巻し、その一端部を接続して直 列回路となし、他の一端部より電流を流した際に、隣接する発熱導体に流れる電 流が相互に逆方向となり、発生する磁力線を打ち消すようにしたので、電気ヒー ターから発生する低周波電流による磁界の発生を減衰でき、電磁波による悪影響 を抑制できる。 As described above with the embodiment, according to the configuration of the electromagnetic wave suppression heater of the present invention, two heating conductors are spirally wound horizontally in parallel, and one end thereof is connected to form a series circuit. However, when current flows from the other end, the currents flowing in adjacent heating conductors are in opposite directions, and the lines of magnetic force generated are canceled out, so that the magnetic field due to the low-frequency current generated from the electric heater is reduced. Generation can be attenuated, and adverse effects due to electromagnetic waves can be suppressed.
【００１４】 また、発熱導体に耐熱ワニスを塗布することによって電磁波を抑制し、かつ絶 縁性・耐熱性に優れた電磁波抑制ヒーターが得られる。[0014] Furthermore, by applying a heat-resistant varnish to the heating conductor, an electromagnetic wave suppressing heater which suppresses electromagnetic waves and is excellent in insulation and heat resistance can be obtained.
【００１５】 したがって、簡便な構成により電磁波を抑制し、安全かつ経済性をも維持し、 加工性を損なわなず、絶縁性・耐熱性に優れた電磁波抑制ヒーターを提供できる 。Therefore, it is possible to provide an electromagnetic wave suppression heater that suppresses electromagnetic waves with a simple configuration, maintains safety and economic efficiency, does not impair workability, and is excellent in insulation and heat resistance.
