以下、実施形態について図１乃至図４を参照して説明する。図１は、作物栽培ハウスの一例であるビニールハウス１０を示す。ビニールハウス１０は、例えば、パイプ機材をビニールシートで覆ってなる。ビニールハウス１０内は、例えば鉢植え１１を栽培する第１のエリア［Ａ］と、育苗箱１２で苗を栽培する第２のエリア［Ｂ］を備える。ビニールハウス１０内は、直接植物を植える直植えのエリアを供える等可能である。第１のエリア［Ａ］および第２のエリア［Ｂ］は、地中１７との間に、発泡スチロールあるいはエアキャップ等からなる断熱材１８を備える。   Hereinafter, embodiments will be described with reference to FIGS. 1 to 4. FIG. 1 shows a greenhouse 10 which is an example of a crop cultivation house. The greenhouse 10 is formed, for example, by covering pipe equipment with a vinyl sheet. The inside of the greenhouse 10 includes, for example, a first area [A] for cultivating potted plants 11 and a second area [B] for cultivating seedlings in a seedling box 12. The inside of the greenhouse 10 can provide a direct planting area where plants are directly planted. The first area [A] and the second area [B] are provided with a heat insulating material 18 made of foamed polystyrene, an air cap or the like between the first area 17 and the underground 17.

ビニールハウス１０は少なくとも一部にカーボン繊維発熱シートであるヒータ２０を備える。例えば第１のエリア［Ａ］では、ヒータ２０は、鉢植え１１の上部を覆う。例えば第２のエリア［Ｂ］では、ヒータ２０を、育苗箱１２の下に敷く。ヒータ２０は、例えば直植えのエリアでは、地中１７に埋設しても良い。   The greenhouse 10 includes at least a heater 20 that is a carbon fiber heating sheet. For example, in the first area [A], the heater 20 covers the upper part of the potted plant 11. For example, in the second area [B], the heater 20 is laid under the seedling box 12. The heater 20 may be embedded in the ground 17 in a direct planting area, for example.

次にヒータ２０について詳述する。ヒータ２０は、図２乃至図４に示すように、例えば複数のカーボン電線２１及びカーボン電線２１を固定する絶縁性のワイヤ２２を備える。カーボン電線２１は、図３に示すようにカーボン繊維（Carbon Fiber）からなる芯線と２１ａ、芯線２１ａを被覆するシリコン被膜２１ｂを備える。カーボン電線２１は、曲げ加工性に優れ断線を生じ難い。カーボン電線２１の芯線２１ａは、単体のカーボン繊維であっても良いし、複数本のカーボン繊維を撚り合わせても良い。芯線２１ａは、複数本のカーボン繊維を撚り合わせることにより、単線のカーボン繊維に比べてより柔軟性に優れる。   Next, the heater 20 will be described in detail. As shown in FIGS. 2 to 4, the heater 20 includes, for example, a plurality of carbon wires 21 and an insulating wire 22 that fixes the carbon wires 21. As shown in FIG. 3, the carbon electric wire 21 includes a core wire made of carbon fiber (Carbon Fiber), 21a, and a silicon coating 21b covering the core wire 21a. The carbon electric wire 21 is excellent in bending workability and hardly breaks. The core wire 21a of the carbon electric wire 21 may be a single carbon fiber, or a plurality of carbon fibers may be twisted together. The core wire 21a is more flexible than a single-wire carbon fiber by twisting together a plurality of carbon fibers.

カーボン電線２１は自己温度制御特性を備える。カーボン電線２１の両側に電圧を掛けて電流を流すと、カーボン電線２１は発熱する。カーボン電線２１は、発熱により一定温度以上になると、抵抗値が増加して電流が流れ難くなり、特定の制御温度を保持する。カーボン電線２１の自己温度制御特性による制御温度は、カーボン電線２１の芯線２１ａの径、長さあるいは、カーボン電線２１に印加する電圧値により任意に設定可能である。   The carbon electric wire 21 has a self-temperature control characteristic. When a current is applied by applying a voltage to both sides of the carbon wire 21, the carbon wire 21 generates heat. When the carbon electric wire 21 reaches a certain temperature or more due to heat generation, the resistance value increases and it becomes difficult for current to flow, and the specific electric control temperature is maintained. The control temperature based on the self-temperature control characteristic of the carbon electric wire 21 can be arbitrarily set by the diameter and length of the core wire 21 a of the carbon electric wire 21 or the voltage value applied to the carbon electric wire 21.

ワイヤ２２は、例えば絶縁性に優れた糸状のものを撚り合せてなる。ワイヤ２２は所定箇所で、複数の繊維の間にカーボン電線２１を挟むことにより、複数のカーボン電線２１を例えば等間隔に配置する。複数のカーボン電線２１の間隔は等間隔でなくても良い。ワイヤ２２上で、カーボン電線２１を挟む箇所を任意に選択すれば、ワイヤ２２は、カーボン電線２１の間隔を容易に調整可能である。またワイヤ２２の間隔及び使用本数も任意である。   The wire 22 is formed by twisting, for example, a thread-like material having excellent insulating properties. The wire 22 is a predetermined location, and the plurality of carbon wires 21 are arranged at regular intervals, for example, by sandwiching the carbon wires 21 between a plurality of fibers. The intervals between the plurality of carbon electric wires 21 may not be equal. If the part which pinches | interposes the carbon electric wire 21 on the wire 22 is selected arbitrarily, the wire 22 can adjust the space | interval of the carbon electric wire 21 easily. Further, the interval and the number of wires 22 used are arbitrary.

ヒータ２０はカーボン電線２１に接続して、電源２６による電力をカーボン電線２１に供給する、給電配線である電源線２３を備える。電源２６は、例えば家庭用電源あるいはビニールハウス１０等で一般に使用される重油ボイラ稼動用電源（１００Ｖあるいは２００Ｖのいずれでも可能である。）等を利用可能である。電源２６は、太陽光発電による電源を利用することも可能である。電源線２３は、カーボン電線２１に例えば２４Ｖの直流の低電圧を供給する。カーボン電線２１に供給する電圧は交流電圧であっても良い。   The heater 20 is connected to the carbon wire 21 and includes a power supply line 23 that is a power supply wiring that supplies power from the power supply 26 to the carbon wire 21. As the power source 26, for example, a household power source or a heavy oil boiler operating power source (100 V or 200 V) that is generally used in the greenhouse 10 or the like can be used. The power source 26 can also use a power source by photovoltaic power generation. The power line 23 supplies a DC low voltage of 24 V, for example, to the carbon electric wire 21. The voltage supplied to the carbon electric wire 21 may be an AC voltage.

ヒータ２０は、カーボン電線２１、ワイヤ２２及び電源線２３を、一体的にラミネート加工する例えば柔軟且つ透明なフィルム２４を備える。フィルム２４によるラミネート加工は、ベースフィルム２４ａ上に、等間隔に配置したカーボン電線２１、ワイヤ２２、電源線２３を配置して、カバーフィルム２４ｂを上から貼り合わせる。ヒータ２０は、ラミネート加工により、カーボン電線２１、ワイヤ２２及び電源線２３をフィルム２４内で固定する。   The heater 20 includes, for example, a flexible and transparent film 24 that integrally laminates the carbon electric wire 21, the wire 22, and the power supply line 23. In the laminating process using the film 24, the carbon electric wires 21, the wires 22 and the power lines 23 arranged at equal intervals are arranged on the base film 24a, and the cover film 24b is bonded from above. The heater 20 fixes the carbon electric wire 21, the wire 22, and the power supply line 23 in the film 24 by laminating.

フィルム２４の素材はラミネート加工可能であればプラスチック等任意である。ラミネート加工の方法は、熱による加工あるいは接着剤による加工等任意である。ヒータ２０のサイズは任意である。例えばヒータ２０を定型サイズに形成しても良いし、ヒータ２０を矢印ｘ方向に長いロール状に形成して、必要長さにカットして使用することも可能である。   The material of the film 24 is arbitrary as long as it can be laminated. The method of laminating is arbitrary such as heat processing or adhesive processing. The size of the heater 20 is arbitrary. For example, the heater 20 may be formed in a standard size, or the heater 20 may be formed in a roll shape that is long in the direction of the arrow x and cut into a necessary length for use.

例えば自己温度制御特性による制御温度を４０℃としたヒータ２０を必要長さにカットして、トンネル状に形成する。トンネル状に形成したヒータ２０で、ビニールハウス１０内の第１のエリア［Ａ］の鉢植え１１の上部を覆う。例えばビニールハウス１０内の温度が、鉢植え１１の適正な育成温度より低下した場合に、電源２６をオンしてカーボン電線２１に通電する。カーボン電線２１は、低電圧で、４０℃の発熱温度を維持し、第１のエリア［Ａ］内を適正な育成温度に保つ。   For example, the heater 20 whose control temperature by the self-temperature control characteristic is 40 ° C. is cut to a required length and formed into a tunnel shape. A heater 20 formed in a tunnel shape covers the upper part of the potted plant 11 in the first area [A] in the greenhouse 10. For example, when the temperature in the greenhouse 10 falls below the proper growing temperature of the potted plant 11, the power supply 26 is turned on and the carbon electric wire 21 is energized. The carbon electric wire 21 maintains a heat generation temperature of 40 ° C. at a low voltage, and maintains the inside of the first area [A] at an appropriate growth temperature.

ヒータ２０は、透明なフィルム２４内に細いカーボン電線２１とワイヤ２２をラミネートするのみであることから、ヒータ２０内の鉢植え１１に太陽光を十分取り入れて、鉢植え１１の生育に有効に作用する。カーボン電線２１は、通電による抵抗値から生じる熱（波長）がカーボン特有の遠赤外線を放射する。カーボン電線２１が放射する遠赤外線は、鉢植え１１の生育により有効に作用する。   Since the heater 20 only laminates the thin carbon electric wires 21 and the wires 22 in the transparent film 24, the heater 20 effectively takes sunlight into the potted plant 11 in the heater 20 and effectively acts on the growth of the potted plant 11. In the carbon electric wire 21, heat (wavelength) generated from a resistance value caused by energization radiates far infrared rays peculiar to carbon. Far-infrared rays radiated from the carbon electric wire 21 act effectively by the growth of the potted plant 11.

カーボン電線２１は、電源２６をオンした際の突入電圧がタングステン或いは他の金属類と比較して極めて低いことから、カーボン電線２１や電源線２３等に大きな負荷が掛かることが無い。カーボン電線２１や電源線２３等の寿命を長く出来る。   Since the inrush voltage when the power source 26 is turned on is extremely low as compared with tungsten or other metals, the carbon wire 21 does not apply a large load to the carbon wire 21, the power line 23, and the like. The lifetime of the carbon electric wire 21 and the power supply line 23 can be extended.

例えば自己温度制御特性による制御温度を例えば４０℃としたヒータ２０を必要長さにカットして、ビニールハウス１０内の第２のエリア［Ｂ］の育苗箱１２の下に敷く。例えばビニールハウス１０内の温度が、育苗箱１２内の苗の適正な育成温度より低下した場合に、電源２６をオンしてカーボン電線２１に通電する。カーボン電線２１は、４０℃の発熱温度を維持し、第２のエリア［Ｂ］の育苗箱１２を底部から暖める。   For example, the heater 20 whose control temperature by the self-temperature control characteristic is 40 ° C., for example, is cut to a required length and laid under the seedling box 12 in the second area [B] in the greenhouse 10. For example, when the temperature in the greenhouse 10 is lower than the appropriate growth temperature for the seedlings in the seedling box 12, the power supply 26 is turned on to energize the carbon wires 21. The carbon electric wire 21 maintains an exothermic temperature of 40 ° C., and warms the seedling box 12 in the second area [B] from the bottom.

実施形態によれば、カーボン電線２１、ワイヤ２２及び電源線２３を、フィルム２４で一体的にラミネート加工してヒータ２０を形成する。温度調整装置を設けることなくユーザが所望する加熱温度を低電圧で得られ、安全性及びエネルギーの節約を得る。実施形態によれば所望サイズのヒータ２０をビニールハウス１０内の所望する領域に設置する。実施形態によれば、化石燃料を利用した重油ボイラや高出力ハロゲンランプ等を用いてビニールハウス１０全体を暖める必要が無い。実施形態は、化石燃料によるＣＯ２温暖化を避け、且つ必要とする領域のみを部分的に暖めることが出来、エネルギーの節約を得る。   According to the embodiment, the heater 20 is formed by integrally laminating the carbon electric wire 21, the wire 22, and the power supply line 23 with the film 24. The heating temperature desired by the user can be obtained at a low voltage without providing a temperature adjusting device, and safety and energy saving can be obtained. According to the embodiment, the heater 20 having a desired size is installed in a desired region in the greenhouse 10. According to the embodiment, it is not necessary to warm the entire greenhouse 10 by using a heavy oil boiler using a fossil fuel, a high-power halogen lamp, or the like. Embodiments can avoid CO2 warming due to fossil fuels and can only partially warm the necessary areas, saving energy.

実施形態によれば、ヒータ２０サイズを容易に調整可能であり、ユーザの使い勝手を向上する。フィルム２４が柔軟性を備えることから、ヒータ２０は加工性に優れ、所望の形状を得られる。フィルム２４が透明であることから、ヒータ２０は透光性に優れ、鉢植え１１の上部を覆っても、ヒータ２０の内部に太陽光を取り入れることが出来、鉢植え１１の生育に優れている。実施形態によれば、ビニールハウス１０内の第１のエリア［Ａ］と第２のエリア［Ｂ］とでヒータ２０の使用形態を変えることが出来る。ヒータ２０は、同じビニールハウス１０内をエリア毎に別々に温度管理できる。   According to the embodiment, the size of the heater 20 can be easily adjusted, and user convenience is improved. Since the film 24 has flexibility, the heater 20 is excellent in workability and can obtain a desired shape. Since the film 24 is transparent, the heater 20 is excellent in translucency, and even if the upper portion of the potted plant 11 is covered, sunlight can be taken into the heater 20 and the potted plant 11 is excellent in growth. According to the embodiment, the usage pattern of the heater 20 can be changed between the first area [A] and the second area [B] in the greenhouse 10. The heater 20 can manage the temperature in the same greenhouse 10 separately for each area.

以上説明した実施形態のカーボン繊維発熱シートは、例えば光を取り入れる必要が無ければ、透明性を備えていなくても良い。また育苗箱１２の下に敷き、あるいは地中１７に埋設する場合等では、カーボン電線をラミネートするフィルムは硬質であっても良い。また複数本のカーボン電線は、直線状でなくても良い。例えば図５に示す第１の変形例のように、ヒータ３０は、フィルム２４内でカーボン電線２１を蛇行して配置しても良い。カーボン電線２１を蛇行させることにより、カーボン電線２１の長さを容易に調整することも可能となる。   The carbon fiber exothermic sheet of the embodiment described above may not have transparency if it is not necessary to take in light, for example. Moreover, when laying under the seedling box 12 or burying it in the ground 17, the film for laminating the carbon electric wire may be hard. Further, the plurality of carbon electric wires may not be linear. For example, as in the first modification shown in FIG. 5, the heater 30 may be arranged by meandering the carbon electric wires 21 in the film 24. By making the carbon wire 21 meander, the length of the carbon wire 21 can be easily adjusted.

またカーボン繊維発熱シートの給電配線の配置位置も任意である。例えば図６に示す第２の変形例のように、ヒータ４０は、フィルム２４内の片側に電源線２３を配置しても良い。さらにカーボン繊維発熱シートは、例えばビニールハウスに直接貼り付ける等して使用することが可能であるし、あるいは水耕栽培等に使用しても良い。またカーボン繊維発熱シートを、融雪や凍結防止機器等に活用することも可能である。カーボン繊維発熱シートに用いるカーボン電線の自己温度制御特性による制御温度は限定されない。カーボン電線の径、長さあるいは、カーボン電線に印加する電圧値を調整して、カーボン電線の自己温度制御特性による制御温度をユーザが必要とする制御温度に設定することが可能である。   The arrangement position of the power supply wiring of the carbon fiber heating sheet is also arbitrary. For example, as in the second modification shown in FIG. 6, the heater 40 may have the power supply line 23 arranged on one side in the film 24. Furthermore, the carbon fiber heat generating sheet can be used by, for example, being directly attached to a greenhouse, or may be used for hydroponics or the like. It is also possible to utilize the carbon fiber heating sheet for snow melting and anti-freezing devices. The control temperature by the self-temperature control characteristic of the carbon electric wire used for a carbon fiber exothermic sheet is not limited. By adjusting the diameter and length of the carbon wire or the voltage value applied to the carbon wire, the control temperature based on the self-temperature control characteristic of the carbon wire can be set to the control temperature required by the user.

この発明の実施形態を説明したが、この実施形態は、例として提示したものであり、発明の範囲を限定することは意図していない。この新規な実施形態は、その他の様々な形態で実施されることが可能であり、発明の要旨を逸脱しない範囲で、種々の省略、置き換え、変更を行うことが出来る。この実施形態やその変形は、発明の範囲や要旨に含まれるとともに、特許請求の範囲に記載された発明とその均等の範囲に含まれる。   Although the embodiment of the present invention has been described, this embodiment is presented as an example and is not intended to limit the scope of the invention. The novel embodiment can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the scope of the invention. This embodiment and its modifications are included in the scope and gist of the invention, and are included in the invention described in the claims and the equivalents thereof.
