Description

과열방지를 위한 원적외선 히터의 전열 코일 장착구조{MOUNTING STRUCTURE FOR ELECTRIC HEATING COIL OF FAR-INFRARED RAY HEATER FOR PREVENTING OVERHEAT}MOUNTING STRUCTURE FOR ELECTRIC HEATING COIL OF FAR-INFRARED RAY HEATER FOR PREVENTING OVERHEAT}

본 고안은 세라믹 보빈 외주에 전열 코일을 나선형으로 감아 발열토록 한 원적외선 히터의 전열 코일 장착구조에 관한 것으로, 원적외선이 발산되는 세라믹 재질의 보빈 외주에 일정한 간격으로 나선홈을 요입 형성하여 전열 코일을 감아 주되, 전열 코일의 피치(pitch)를 전열 코일 굵기의 2.7배 이상으로 하고, 전열 코일이 감겨지는 나선홈의 간격은 전열 코일 외경의 1배 이상으로 넓게 하여 과열을 방지하므로서, 쇼트에 따른 발열성능 저하 및 화재발생의 위험성을 최소화시켜 히터의 안전성을 보다 향상시킨 것이다.The present invention relates to a heat transfer coil mounting structure of a far-infrared heater that spirally wound a heat transfer coil on a ceramic bobbin outer periphery, and forms a spiral groove at a predetermined interval on a bobbin outer periphery of a ceramic material emitting far-infrared rays to wind the heat coil. However, the pitch of the heating coil should be 2.7 times or more of the thickness of the heating coil, and the spacing of the spiral grooves around which the heating coil is wound will be wider than 1 times the outer diameter of the heating coil to prevent overheating, thereby generating heat generation performance according to the short. The safety of the heater is further improved by minimizing the risk of degradation and fire.

이제까지는 히터의 발열성을 높이기 위해 전열 코일(니크롬 선)의 감김 피치를 코일의 외경보다 좁게 하는 동시에 전열 코일이 감기는 세라믹 보빈 외주의 나선홈 간격을 최대한 좁게 형성하였던 것이었다.Until now, the winding pitch of the heat transfer coil (nichrome wire) was narrower than the outer diameter of the coil in order to increase the heat generation property of the heater, and at the same time, the spacing of the spiral grooves of the ceramic bobbin outer periphery to which the heat transfer coil was wound was formed as narrow as possible.

상기의 경우 보빈의 전체 체적을 작게 하여 단위 면적당 발열성능을 높일 수 있었던 것이나, 상대적으로 과열의 위험성이 높아 전열 코일의 수명을 단축시키게 되었으며, 코일 피치가 좁아 쇼트가 발생되기 쉬워 불량이 많았던 것이며, 화재발생의 위험성이 높았던 것이다.In the above case, the total volume of the bobbin was reduced to increase the heat generation performance per unit area, but the risk of overheating was relatively high, which shortened the life of the electric coil. There was a high risk of fire.

본 고안은 상기와 같은 기존의 전열 코일 장착구조에서 제기되는 문제점을 해결하므로서 원적외선 전기 히터의 사용시 그 안전성을 높이고, 이의 사용수명을 보다 장기화시킬 수 있는 전열 코일 장착구조를 제공함에 그 목적이 있는 것이다.The present invention aims to provide a heat transfer coil mounting structure that can improve the safety of the use of a far-infrared electric heater and prolong its service life by solving the problems posed by the conventional heat transfer coil mounting structure as described above. .

상기의 목적 달성을 위한 본 고안의 기술구성을 첨부도면에 의거 구체적으로 설명하면 다음과 같다.When described in detail based on the accompanying drawings the technical configuration of the present invention for achieving the above object.

본 고안은 세라믹 보빈 외주에 전열 코일을 나선형으로 감아 발열토록 한 원적외선 히터의 전열 코일 장착구조에 있어서,The present invention is a heat transfer coil mounting structure of a far-infrared heater that spirally wound a heat transfer coil around a ceramic bobbin,

전열 코일(3)이 감겨지는 세라믹 보빈(1)의 외면에 요입 형성시킨 나선홈(2)의 간격(C)을 상기 전열 코일 외경(P)의 1배 이상이 되게 하고, 전열 코일(3)의 피치(P1)를 전열 코일 굵기의 2.7배 이상이 되게 구성한 것을 특징으로 하는 과열방지를 위한 원적외선 히터의 전열 코일 장착구조 인 것이다.The spacing C of the spiral grooves 2 recessed in the outer surface of the ceramic bobbin 1 to which the heat transfer coil 3 is wound is made to be at least 1 times the outer diameter P of the heat transfer coil 3, and the heat transfer coil 3 The pitch (P1) of the heat transfer coil mounting structure of the far-infrared heater for preventing overheating, characterized in that configured to be at least 2.7 times the thickness of the heat transfer coil.

본 고안에서 사용되는 세라믹 보빈(1)은 기존의 세라믹 보빈(1)의 형상을 그대로 이용하는 것이나, 그 체적은 기존의 경우보다 크게 하는 것이다.The ceramic bobbin 1 used in the present invention uses the shape of the existing ceramic bobbin 1 as it is, but the volume thereof is larger than that of the conventional case.

첨부도면중 미설명부호 4는 보빈(1)이 조립 장착되는 설치 고정관을 나타내는 것이다.Reference numeral 4 in the accompanying drawings indicates an installation fixing tube to which the bobbin 1 is assembled.

본 고안은〔도 4〕의 시험도표에서 보는 바와 같이. 코일 피치(P1)와 나선홈 간격(C)을 넓게 함에 따라 히터 온도가 점차 내려감을 알 수 있다.The present invention is as shown in the test diagram of [Fig. 4]. It can be seen that the heater temperature gradually decreases as the coil pitch P1 and the spiral groove spacing C are widened.

즉, 코일 피치(P1)가 1mm, 나선홈 간격(C)이 3mm 일 때 히터 온도는 약 830℃가 되었고, 코일 피치(P1)가 1.3mm, 나선홈 간격(C)이 3.2mm 일 때 히터 온도는 약 730℃로 내려갔으며, 코일 피치(P1)가 1.6mm, 나선홈 간격(C)이 4mm 일 때 히터 온도는 약 650℃로, 코일 피치(P1)가 1.7mm, 나선홈 간격(C)이 4.2mm 일 때 히터 온도는 약 600℃로 내려가는 것이 시험결과 확인된 것이다.That is, when the coil pitch P1 is 1 mm and the spiral groove spacing C is 3 mm, the heater temperature is about 830 ° C., and the coil pitch P1 is 1.3 mm and the spiral groove spacing C is 3.2 mm. The temperature was lowered to about 730 ° C, and the heater temperature was about 650 ° C when the coil pitch (P1) was 1.6mm and the spiral groove spacing (C) was 4mm, the coil pitch (P1) was 1.7mm, and the spiral groove spacing (C) The test result confirms that the heater temperature drops to about 600 ° C when) is 4.2mm.

본 고안은 이상 설명된 바와 같이, 전열 코일(3)이 감겨지는 세라믹 보빈(1)의 외주면에 나선홈(2)을 요입 형성시킴에 있어, 나선홈의 간격(C)을 코일 외경(P)의 1배 이상으로 형성하고, 코일(3)의 피치(P1)는 코일 굵기의 2.7배 이상으로 형성하는 것이어서 전열 히터의 안전성 기준이 되는 650℃ 이하의 발열온도가 유지되도록 구성한 것이다.As described above, in forming the spiral grooves 2 in the periphery of the ceramic bobbin 1 on which the heat transfer coils 3 are wound, the spacing C of the spiral grooves is the coil outer diameter P. And the pitch P1 of the coil 3 is formed to be 2.7 times or more of the thickness of the coil, so that the exothermic temperature of 650 ° C. or less, which is a safety criterion of the electrothermal heater, is maintained.

따라서, 세라믹 보빈과 전열 코일을 사용한 원적외선 전기 히터의 사용시 전열 코일간의 간격과 나선홈의 간격이 기존의 경우보다 넓어지게 구성한 것이어서 전열 히터의 안전성 기준인 650℃ 이하의 발열온도가 유지되어 과열이 방지되는 것이며, 쇼트에 의한 불량발생이나 화재발생의 위험성이 최소화되므로서 그 안전성이 크게 높아지고, 이의 사용수명이 또한 장기화 되는 효과를 제공하는 것이다.Therefore, when using a far-infrared electric heater using a ceramic bobbin and a heat transfer coil, the spacing between the heat coils and the spacing of the spiral grooves are wider than in the conventional case, so that a heat generation temperature of 650 ° C. or less, which is a safety criterion of the heat heater, is maintained to prevent overheating. By minimizing the risk of defects or fires caused by shorts, the safety is greatly increased, and the service life thereof is also prolonged.
