Description
【発明の詳細な説明】
（産業上の利用分野）
この発明は土壌の恒温化を目的としたもので、温室、畑
地、ゴルフ場等において土壌温度を植物の生育に適する
温度に保持することにより、年間を通じ植物の育成栽培
を行う産業分野に属する。[Detailed Description of the Invention] (Field of Industrial Application) This invention aims to maintain a constant temperature of soil by maintaining the soil temperature at a temperature suitable for plant growth in greenhouses, fields, golf courses, etc. , belongs to the industrial field that involves growing and cultivating plants throughout the year.
（従来の技術）
従来土壌温度を一定の範囲に保つ為には、温室等におい
てはＶ温を一定の温度に保つように至内空気の加温によ
る場合と、土中に温水配管を施し、これにより土壌温度
を保持する場合とが広く知られている。(Prior art) Conventionally, in order to maintain the soil temperature within a certain range, in greenhouses, etc., one method is to heat the indoor air to maintain the V temperature at a certain temperature, and the other is to install hot water piping in the soil. It is widely known that soil temperature is maintained by this method.
（発明により解決すべき問題点）
然し乍ら、気温上昇によって土壌温度を高めようとすれ
ば、表面と土中との土壌温度を均一化することがむつか
しいのみならず、気温を相当高くしなければ、土壌温度
を所定の恒温に出来ない問題点があった。(Problems to be Solved by the Invention) However, if we try to raise the soil temperature by increasing the temperature, it is not only difficult to equalize the soil temperature between the surface and the soil, but also the temperature must be raised considerably. There was a problem that the soil temperature could not be maintained at a constant temperature.
又、温水配管などによる時には、必要箇所へ所定間隔の
配管をする為には、設備費を要するのみならず、局部的
温度コントロールがむつかしく、かつボイラーなど常時
運転しておいて必要時に温水を循環させなければならず
、更にボイラーに近い程高温になり易い問題点があった
。In addition, when hot water piping is used, not only does it require equipment costs to install piping at specified intervals to the necessary locations, but it is also difficult to control local temperature, and it is necessary to keep a boiler running all the time and circulate hot water when necessary. Furthermore, there was a problem that the closer the boiler was, the higher the temperature was likely to be.
（問題点を解決する為の手段）
然るにこの発明は土中へ所定深さに電気による面発熱体
を埋設し、各面発熱体とこれを結ぶ電線によって発熱回
路を構成し、前記回路へサーモスタットを介装したので
、土壌は一側であろうと中央部であろうと均等に加温さ
れ自動調温されて容易に目的を達成することができる。(Means for Solving the Problems) However, in this invention, electrical surface heating elements are buried in the soil at a predetermined depth, a heating circuit is formed by each surface heating element and electric wires connecting them, and a thermostat is connected to the circuit. Because the soil is heated evenly, whether on one side or in the center, the temperature is automatically controlled and the purpose can be easily achieved.

って定まる自動恒温特性を有する。The surface heating element according to the present invention has a property that the temperature does not rise above a set temperature no matter how many hours it is energized, and has a plate-like, rod-like, or tubular shape (utilizing the invention of Japanese Patent Application No. 148733/1982). It has automatic constant temperature characteristics determined by the blending ratio of the constituent materials.
従って、例えば限度４０℃の板状の面発熱体を用いれば

ことができる。Therefore, for example, if a plate-shaped surface heating element with a limit of 40° C. is used, even if the thermostat fails, there is no risk that the soil temperature will exceed 40° C. regardless of the outside temperature, and safety is extremely high. In addition, since it can be electrically controlled, an automated system can be easily adopted, and it can also be easily incorporated into a fully automated system for recording each part, remote control, and constant temperature of the soil.

Bury to a depth of 50 cm to 100 clTl between ~50 cTn. Various shapes and dimensions can be considered for the surface heating element, but from the viewpoint of ease of handling, for example, length and width (35 cm to 7
5cm) The thickness is preferably about 1.5cm.

度には上昇しない。An even greater advantage is that this invention can be set directly into the soil at a low voltage of 100V, which is the least dangerous voltage, regardless of the presence or absence of a roof or other shield, and it is possible to use conventional nichrome wires. Compared to electric resistance type heaters that use similar devices, it requires much less electricity. For example, the amount of electricity used by this surface heating element set at 40℃ is 1
Since it is 0.4 AMP for 1 hour at 00 V, it is not comparable to conventional electric heaters. Also, if the temperature is set at 40°C, the temperature will not rise above that.
