本発明は水道配管等の凍結防止用発熱保温ヒーターに関
する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a heat generating heater for preventing freezing of water pipes and the like.
従来より寒冷地においては、外気温度の低下により通常
の水道配管では水道水が凍結することがある。そこで配
管に保温カバーを取付けるが、これだけでは温度低下が
長時間に亘った際、配管内の水が凍結することもあるの
で、水を配管より抜取る装置があった。また複雑な配管
あるいは使用上水を抜取ることができない配管が原因す
る凍結、さらには水抜取り装置の操作忘れによる凍結も
ある。これら問題を解決するために、近年配管の外周と
保温カバーとの間に一般に線状または帯状の発熱体を螺
旋状に巻付け、この発熱体により配管を加熱し凍結を防
止する手段が実施されている。In traditionally cold regions, tap water may freeze in normal water pipes due to a drop in outside temperature. Therefore, heat insulating covers were attached to the pipes, but if this alone could cause the water in the pipes to freeze if the temperature dropped for a long time, there was a device to remove the water from the pipes. Freezing may also occur due to complicated piping or piping from which water cannot be drained during use, or even due to forgetting to operate the water draining device. In order to solve these problems, in recent years a method has been implemented in which a linear or band-shaped heating element is wound spirally between the outer periphery of the piping and the insulation cover, and this heating element heats the piping to prevent it from freezing. ing.
しかし、従来の線状あるいは帯状の発熱体を螺旋状に配
管に巻付ける際、二重巻になる恐れがある。また発熱体
は配管に密着して巻かないと、その加熱効果が低下する
ので１例えば配管に１０数メートルの巻付けの場合は、
ビニールテープ等により弛みを防止しながら巻付ける必
要が生じる。However, when winding a conventional linear or band-shaped heating element around a pipe in a spiral manner, there is a risk of double winding. In addition, if the heating element is not wrapped tightly around the pipe, its heating effect will be reduced.1 For example, if the heating element is wrapped around the pipe for more than 10 meters,
It becomes necessary to wrap it while preventing loosening using vinyl tape or the like.
このような巻付けでは他の障害物のため巻付きが困難と
なったり、また作業者の電気的知識の不足から針金等の
電導体で弛み防止を施工することがある。二重巻付部分
および針金による弛み防止部分においては、電気的ショ
ート状態となりそれらの部分に異状発熱が生じ１発火す
ることがある。In such winding, winding may be difficult due to other obstacles, or due to lack of electrical knowledge of the operator, a conductor such as wire may be used to prevent loosening. In the double-wound portion and the loosening prevention portion using the wire, an electrical short may occur, causing abnormal heat generation in those portions and causing a fire.
寒冷な外気温度を遮断するための保温カバーは、保温効
果と経済性の点から、一般に発泡スチロール系材料で構
成されており、これは低温には強いが、高温には弱く火
災が発生することがある。Thermal covers used to block out cold outside temperatures are generally made of styrofoam material, which is resistant to low temperatures but weak against high temperatures and can cause fires, due to its heat retention effect and economic efficiency. be.
また、従来の上記発熱体はニクロム線等の金属の抵抗体
の電気抵抗で発熱するもので、ニクロム線の特定の長さ
により所定の発熱量を発生するものであって、その特定
の長さのものを異状発熱防止のため定められた巻き間隔
で使用しなければならない、そこで配管の長さの都合上
１発熱体に余分の長さが生じても切断することはできず
、そのため配管に対し過密な巻付けをして異状発熱を発
生する。また配管に対して発熱体の長さが不足する場合
でも、電気抵抗の変化により所定の発熱が得られないた
めの継ぎ足すことができず、実際の施工上の不便があっ
た。In addition, the conventional heating element described above generates heat due to the electrical resistance of a metal resistor such as a nichrome wire, and generates a predetermined amount of heat depending on a specific length of the nichrome wire. The heating element must be used at a specified winding interval to prevent abnormal heat generation, and due to the length of the piping, even if one heating element has extra length, it cannot be cut. On the other hand, if the wire is wrapped too tightly, abnormal heat generation will occur. Furthermore, even if the length of the heating element is insufficient for the piping, it is impossible to add more because the desired heat generation cannot be obtained due to changes in electrical resistance, which is inconvenient in actual construction.
上記のように、従来の水道管の凍結防止用手段は線状あ
るいは帯状の金属抵抗発熱体を配管に保温カバーとの間
に螺旋状に巻付けた構造であるので、施工によっては火
災事故の発生の危険性があり、また使用条件に応じて、
施工上切断と継ぎ足しができないという制約があり不便
であった。As mentioned above, the conventional means for preventing water pipes from freezing consists of a linear or strip-shaped metal resistance heating element wrapped spirally around the pipes and a heat insulating cover, which may lead to fire accidents depending on the construction. Depending on the risk of occurrence and the conditions of use,
This was inconvenient due to the restriction that cutting and joining were not possible during construction.
本発明は、上記問題点を解消し、異常発熱による火災事
故の発生を完全に防止し、また施工上の切断、継ぎ足し

のである。The present invention solves the above problems, completely prevents the occurrence of fire accidents due to abnormal heat generation, and is a heat-generating heat-retaining heater that can be cut and added freely during construction, and is extremely easy to install on piping. The purpose is to provide the following.

There are 10 locations for a length of 1 meter.Since the heating element is not attached to the 3e part, the horizontal cutting of the parallel conductor in the secondary direction and the connection of the heating element in the secondary direction will reduce the heat generated per unit of the heating element. Since the amount remains unchanged, it can be cut and connected to any length for use. Furthermore, the structure does not allow double mounting of heating elements on the piping, so heat generation can be completely avoided. In addition, since it is made of an elastic material with an opening formed in the longitudinal direction, it can be easily fitted to a water pipe by expanding it, and it does not easily fall off due to its own gravity, so there is no need to hold it with wire, etc. , overheating and fire caused by electrical shorts are completely prevented.
