본 고안은 가정 또는 의료용 열기등의 사용되는 경박형 소형 세라믹 히터 내부에 바이메탈 스위치를 내장하여 세라믹히터의 과열에 의한 열선의 단선을 방지할 수 있게된 경박형 세라믹 히터의 보호 장치에 관한 것이다.The present invention relates to a protection device for a thin and thin ceramic heater that can prevent the disconnection of the heating wire due to overheating of the ceramic heater by embedding a bimetal switch in the thin and thin ceramic heater used in home or medical heat.

종래의 경우 가정 또는 의료용 열기등에 사용되는 세라믹 히터에 있어서는 단일 세라믹 히터내에 열선만 넣은 상태에서 별도의 열 감지장치를 외부에 삽입하여 사용하였기 때문에 세라믹 히터의 과용에 의해 히터선이 단선되는 경우가 있을뿐만 아니라 체결시 부주의로 인하여 접점의 불량이 발생되어 온도 과열로 인한 세라믹 히터내의 열선이 단선되던 결점이 있었다.In the conventional ceramic heater used for home or medical heat, since a separate heat sensing device is used in the state in which only a heating wire is placed in a single ceramic heater, the heater wire may be disconnected due to overuse of the ceramic heater. In addition, due to inadvertent contact due to the inadequate fastening, the heating wire in the ceramic heater was disconnected due to the overheating temperature.

따라서 본 고안은 이와 같은 종래의 결점을 해결하기 위하여 안출된 것으로 첨부된 도면에 의하여 그 구성과 작용효과를 설명하면 다음과 같다.Therefore, the present invention was devised to solve such a conventional drawback, and the construction and operation effects will be described with reference to the accompanying drawings.

발열판(1)의 내부에 열선(2)을 내장하고 열선(2)에서 연결되는 리드선(3)의 중간을 절단한 뒤 발열판(1)면에 형성된 홈(4)내로 바이메탈 스위치(5)를 삽입 리드선(3)의 절단부인 양선단에 접합시킨후 단열재(6)를 열선부에 삽지시켜 놓고 또한 그 상면으로는 뚜껑(7)을 삽입 안착 밀폐시켜서 구성되어진 것으로 미 설명 부호 8, 8＂는 단자인 것이다.The heating wire 2 is built in the heating plate 1, the middle of the lead wire 3 connected from the heating wire 2 is cut, and then the bimetal switch 5 is inserted into the groove 4 formed on the surface of the heating plate 1. After joining to both ends of the lead wire 3, the heat insulating material 6 is inserted into the hot wire part, and the lid 7 is inserted and seated and sealed on the upper surface thereof. It is

이와 같이 구성된 본 고안의 작용 효과를 설명하면 다음과 같다.Referring to the effects of the present invention configured as described above are as follows.

상기와 같은 본원의 경박형 세라믹 히터의 보호장치에 있어서는 가정이나 의료용 열기등에 사용되는 것으로 발열판(1)면에 형성된 홈(4)내로 삽입되어 있으면서 리드선(3)의 절단부인 양선단에 접합되어 있는 바이메탈스위치(5)는 내부에 단자(8)(8')를 가지고 있어 과용의 1차측과 2차측을 통제하도록 함에 따라서 단자(8)(8')가 전부 OFF되면 전원이 일정 보호시간 동안 차단되고 또한 미 달성 온도에서는 단자(S')부만 열려 전원의 용량을 일부 반감하게 하여 열선(2)의 급상승온도를 방지하고 최종시에 가서 차단함으로써 세라믹 히터의 과열에 의한 열선(2)의 단선등을 방지할 수 있게 하며 경박형 세라믹 히터를 보호할 수 있게 된 것이다.In the protection device of the thin-thin ceramic heater of the present application, which is used for home or medical heat, etc., it is inserted into the groove 4 formed on the surface of the heat generating plate 1 and joined to both ends of the cut line of the lead wire 3. The bimetal switch 5 has terminals 8 and 8 'inside to control overuse primary and secondary side, so that when the terminals 8 and 8' are all turned off, the power is cut off for a certain protection time. In addition, at the unattained temperature, only the terminal S 'is opened to partially reduce the capacity of the power supply to prevent the sudden rise in temperature of the heating wire 2 and then shut off at the end to cut off the heating wire 2 due to overheating of the ceramic heater. It is possible to prevent and to protect the thin-thin ceramic heater.
