본 고안은 전기커피포트나 전기다리미등의 전기발열기구에 사용되는 히터에 관한 것으로, 특히 발열기능과 항온유지기능을 가지는 PTC 서미스터를 발열체로 내장하고 가열용수속에 직접 노출시킬 수 있게 되어 있는 히터를 제공하려는 것이다.The present invention relates to a heater used in electric heating devices such as electric coffee pots and irons, in particular, a heater that is capable of directly exposing the heating element to a PTC thermistor having a heating function and a constant temperature holding function as a heating element. Is to provide.
종래의 발열기구는 일반적인 시이즈히터나 니크롬선등의 금속발열체를 사용하는 것으로서 전력소모가 클뿐아니라 발열에 의하여 쉽게 산화되거나 단선되는 등의 문제점이 지적되는 것이었으며 과열에 의한 화재발생의 위험도 저적 되는 것이었다.Conventional heating devices use metal heating elements such as general size heaters and nichrome wires, which are not only large in power consumption, but also easily oxidized or disconnected due to heat generation, and have a low risk of fire due to overheating. .
본 고안은 이와같은 문제점을 개선하기 위한 것으로 사용시간에 관계없이 과열되지 아니하며 전력소모가 적고 내구적인 히터를 제공하려는 것으로, 발열기능과 항온유지기능을 가지는 PTC 서미스터를 지지판과 방열판 사이에 내장하고 또한 히터의 부착수단을 포함하는 것을 특징으로 하는 것이다.The present invention is to improve the above problems and to provide a durable heater that does not overheat regardless of time of use and has a low power consumption. A PTC thermistor having a heating function and a constant temperature holding function is built between a support plate and a heat sink. It characterized in that it comprises a heater attachment means.
본 고안을 첨부도면에 따라서 상세하게 설명하면 다음과 같다.Referring to the present invention in detail according to the accompanying drawings as follows.
원판상의 알루미늄방열판(1)의 외연에 결합턱(8)을 형성하여 내부에 공간부가 형성되게 방열판(1)에 결합되는 지지판(2)을 그 외면의 절곡턱(7)으로 상기 결합턱(8)에 수밀이 유지도게 포설고정하여 히터(3) 본체를 구성한다.The coupling jaw 8 is formed on the outer edge of the disc-shaped aluminum heat dissipation plate 1 by a support plate 2 coupled to the heat sink 1 so that a space is formed therein. ) Is installed so that the watertightness is maintained so as to constitute the heater (3) body.
티탄산바륨(BaTio3)계의 세라믹(Cermamic) 조성물로서 큐리온도 이하에서는 보통의 발열체로서 기능을 가지며 큐리온도에서 부터 급격히 저항이 증가되어 부도체의 성질을 가지는 PTC 서미스터(PH1-PH7)는 상기 지지판(2)의 내면에 부착되어 지지판(2)과 방열판(1) 사이의 공간부내에서 방열판(1)이 근접되어 PTC 서미스터의 발열이 방열판(1)을 통해 방열될 수 있게 구성되어 있다.A PTC thermistor (PH 1 -PH 7 ) having a barium titanate (BaTio 3 ) -based ceramic (Cermamic) composition which functions as a normal heating element below the Curie temperature and rapidly increases resistance from the Curie temperature, thus having a non-conductive property. Attached to the inner surface of the support plate 2, the heat dissipation plate 1 is adjacent in the space between the support plate 2 and the heat dissipation plate 1, so that the heat generation of the PTC thermistor can dissipate through the heat dissipation plate 1.
지지판(2)의 중앙응기부(9)에 외주면에 스크류를 가지는 리드선도입관(5)을 수밀이 유지되게 고정하고 있으며, 리드선도입관(5)의 주면의 스크류상에는 히터고정수단으로 상기 융기부(9)에 수밀이 유지되게 밀착되는 수압너트(4)와 히터(3)를 가전제품에 기계적으로 고정하기 위한 가압너트(10)를 결합하였다.The lead wire introduction pipe 5 having the screw on the outer circumferential surface of the support plate 2 is fixed to the central condenser 9 so as to maintain the watertightness, and the ridge is formed on the screw of the main surface of the lead wire introduction pipe 5 by the heater fixing means. (9) was combined with a pressure nut (10) for mechanically fixing the water pressure nut (4) and the heater (3) to be kept in close contact with the watertight.
또한 PTC 서미스터(PH1-PH7)에 전원을 공급하기 위한 리드선(6),(6')은 도입관(5)의 구멍(11)을 통하여 상기 서미스터에 접속시켜서된 것이다.The lead wires 6 and 6 'for supplying power to the PTC thermistors PH 1 to PH 7 are connected to the thermistors through the holes 11 of the inlet pipe 5.
본 고안의 작용효과를 설명하면 다음과 같다.Referring to the effect of the present invention is as follows.
히터(3)를 전기커피포트에 조립하는 것을 예로서 히터의 조립을 설명하면 전기커피포트의 바닥구멍에 포트내에서 리드선도입관(5)을 끼운다음 포트의 바닥외측으로 나온 도입관(5)의 스크류에 너트(10)를 채움으로써 두 너트(4).(10) 사이에 커피포트의 바닥부재가 물리게 고정하면 되는 것이다. 이때 너트(4),(10)와 커피포트의 바닥부재 사이에는 수밀이 유지되게 하는 것이며 히터(3)는 커피포트 바닥위에 떠있는 상태로 조립되는 것이다.Assembling the heater as an example of assembling the heater 3 into the electric coffee pot, the lead wire introduction pipe 5 is inserted into the bottom hole of the electric coffee pot in the pot, and then the inlet pipe 5 which comes out of the bottom of the pot. Fill the nut 10 to the screw of the nut 4 and the bottom member of the coffee pot is fixed between the (10). At this time, watertightness is maintained between the nuts 4 and 10 and the bottom member of the coffee pot, and the heater 3 is assembled in a floating state on the bottom of the coffee pot.
히터(3)는 가열동작은 포트내에 물을 넣고 포트외측으로 돌출된 리드선(6),(6')에 70V-240V의 교류 전압 가하면 리드선(6),(6')을 통하여 전원에 접속되는 PTC 서미스터가 발열하게 되고 이 열은 방열판(1)과 지지판(2)을 동하여 방열되는데 특히 열전도호율이 좋은 알루미늄방열판(1)을 통하여 물을 덥힐 수 있게 되는 것이고, PTC서미스터는 큐리온도 이하에서 공급전류에 의해 발열되며, 발열에 의하여 큐리온도에 이르게 되면 저항이 증가되어 부도체의 성질을 가지게 되므로 발열후 항온이 유지되어 과열이 방지되는 것이며, 니크롬선등의 금속발열체와는 달리 소모전류가 적어 전력소모가 적게 되는 것이고 금속발열체와 같이 열화되지않기 때문에 내구성을 유지할 수 있게 되는 것이다.The heater 3 is connected to the power supply through the lead wires 6 and 6 'when heating is applied to the lead wires 6 and 6' protruding outward from the pot, and the 70 V to 240 V AC voltage is applied to the heaters. The PTC thermistor generates heat, and this heat is radiated by moving the heat sink 1 and the support plate 2, in particular, to heat water through the aluminum heat sink 1 having good thermal conductivity, and the PTC thermistor is below the Curie temperature. It generates heat by supply current, and when it reaches Curie temperature by heat, resistance increases and it has non-conductor properties, so it maintains constant temperature after heat and prevents overheating. Unlike metal heating elements such as nichrome wire, it consumes less power. Since it is less consumed and does not deteriorate like a metal heating element, durability can be maintained.
상기와 같이 본 고안은 발열체로서 PTC 서미스털르 사용함으로서 전력소모가 적고 내구적이며 항온이 유지되어 과열되지 않는 히터를 제공하게 된 것이다.As described above, the present invention uses a PTC thermistor as a heating element, thereby providing a heater with low power consumption, durability, and constant temperature, which does not overheat.
