각종 부품이 설치된 본체와, 본체 내부 일측에 수평으로 복수개 설치된 시즈히터와, 상기 시즈히터의 후방에 설치된 송풍팬으로 구성된다.A main body provided with various components, a sheath heater provided in plural horizontally on one side of the main body, and a blowing fan provided at the rear of the sheath heater.
이때, 송풍팬에 의해 유입된 공기는 송풍팬을 통해 전방에 설치된 시즈히터에 열접촉되어 온풍으로 전환된 후 본체의 외부로 배출된다.At this time, the air introduced by the blowing fan is heat-contacted to the sheath heater installed in front through the blowing fan is converted into warm air and then discharged to the outside of the main body.
하지만, 상기한 종래의 시즈히터는 다음과 같은 문제가 발생하였다.However, the above-mentioned conventional sieve heaters have the following problems.
첫째, 시즈히터가 욕조나 족온기 등의 습식에 사용될 경우, 물이 순간적으로 기화되면서 기화열에 의해 발열체의 온도가 급격히 낮아지므로, 발열체의 온도를 다시 높이기 위해서는 전기 에너지의 소모가 증가되는 문제가 발생하였다.First, when the sheath heater is used in wet, such as a bath or foot temperature heater, the temperature of the heating element is rapidly lowered by the vaporization heat while the water is evaporated momentarily, the problem that the consumption of electrical energy is increased to increase the temperature of the heating element again It was.
둘째, 물에 항상 노출되어 있기 때문에, 장기간 사용하게 되면 물속에 함유되어 있는 각종 미네랄이 시즈히터의 표면에 부착되어 스케일이 생기고 누적이된다.Second, because it is always exposed to water, when used for a long time, various minerals contained in the water adhere to the surface of the sheath heater, resulting in scale and accumulation.
이러한 스케일은 열전도를 방해하게 되고 시즈히터의 금속보호관의 부식을 촉진시키게 되며, 나아가 시즈히터가 파손되는 문제가 발생할 수도 있다.Such a scale interferes with heat conduction, promotes corrosion of the metal sheathing tube of the sheath heater, and may cause a problem that the sheath heater is broken.
본 발명은 상기한 과제를 해결하기 위해 안출된 것으로서, 본 발명의 목적은 온도에 따라 저항값이 달라지는 정온특성을 발휘하여 에너지 소모를 줄이고, 물에 노출되더라도 부식이 발생하지 않도록 한 습식 발열체를 제공하고자 한 것이다.The present invention has been made to solve the above problems, and an object of the present invention is to provide a wet heating element that exhibits a constant temperature characteristic that the resistance value varies depending on temperature to reduce energy consumption and prevent corrosion even when exposed to water. It would be.
이를 위해, 단자핀에 연결되며 전원의 공급에 의해 발열하는 열선과, 상기 열선을 피복하는 피복층으로 구성된 발열체에 있어서, 상기 열선은 몰리브덴 와이어로 이루어지고, 상기 피복층은 산화 마그네슘이 충진된 SUS관과, 상기 SUS관의 외부를 감싸도록 설치된 동(銅)관으로 이루어진 것이 바람직하다.To this end, the heating element is connected to the terminal pin and generates a heating wire that generates heat by the supply of power, and the heating layer consisting of a coating layer for covering the heating wire, the heating wire is made of molybdenum wire, the coating layer is SUS tube filled with magnesium oxide and It is preferable that the copper tube is installed to surround the outside of the SUS tube.
이때, 상기 동관의 외면에는 복수의 방열핀이 설치되되, 상기 방열핀과 동관은 금 도금이 이루어진 것이 바람직하다.At this time, a plurality of heat dissipation fins are installed on the outer surface of the copper tube, and the heat dissipation fins and the copper tube are preferably made of gold plating.
본 발명에 따른 습식 발열체에 의하면 다음과 같은 효과가 있다.According to the wet heating element according to the present invention has the following effects.
첫째, 발열체의 발열원인 몰리브덴 열선은 자동으로 정온유지를 수행하는 특성이 있기 때문에, 저온의 액체가 직접 접촉되더라도 표면 온도가 급냉되는 경우가 발생하지 않게 된다.First, since the molybdenum heating wire which is a heating source of the heating element has a characteristic of automatically maintaining a constant temperature, the surface temperature is not rapidly cooled even when a low temperature liquid is directly contacted.
이에 따라, 액체를 기화시키거나 데우는데 있어서 에너지 소모를 절감시킬 수 있는 효과가 있다.Accordingly, there is an effect that can reduce the energy consumption in vaporizing or warming the liquid.
특히, 몰리브덴 열선을 감싸고 있는 SUS재질의 관은 몰리브덴 열선의 과도한 열이 외부로 유출되는 것을 방지하여 발열체의 표면 온도를 일정 온도 이상으로 유지시키기 때문에 발열체의 정온 유지 기능을 극대화시키는 효과가 있다.In particular, the SUS material surrounding the molybdenum heating wire prevents the excessive heat of the molybdenum heating wire to flow to the outside, thereby maintaining the surface temperature of the heating element above a certain temperature, thereby maximizing the constant temperature maintaining function of the heating element.
둘째, 발열체의 외부로 노출된 표면 즉, 액체가 접촉되는 면의 재질이 동(銅)재질로 이루어지기 때문에 부식 방지에 대한 효과가 탁월하다.Second, since the material of the surface exposed to the outside of the heating element, that is, the surface in contact with the liquid is made of copper (재) material is excellent in preventing corrosion.
게다가, 동관 및 방열핀에 금이 더 도금됨으로써 부식을 방지에 대한 효과가 극대화될 수 있다.In addition, the gold is further plated on the copper tube and the heat radiating fins to maximize the effect on preventing corrosion.

상기한 목적을 달성하기 위한 최선의 형태는 다음과 같다.The best mode for achieving the above object is as follows.
단자핀에 연결되며 전원의 공급에 의해 발열하는 열선과, 상기 열선을 피복하는 피복층으로 구성된 발열체에 있어서, 상기 열선은 몰리브덴 와이어로 이루어지고, 상기 피복층은 산화 마그네슘이 충진된 SUS관과, 상기 SUS관의 외부를 감싸도록 설치된 동(銅)관으로 이루어진 것을 특징으로 하는 습식 발열체를 제공한다.A heating element comprising a heating wire connected to a terminal pin and generating heat by supply of power, and a coating layer covering the heating wire, wherein the heating wire is made of molybdenum wire, the coating layer is a SUS tube filled with magnesium oxide, and the SUS It provides a wet heating element, characterized in that consisting of a copper tube installed to surround the outside of the tube.
이때, 상기 동관의 외면에는 복수의 방열핀이 설치되되, 상기 방열핀과 동관은 금 도금이 이루어진 것이 바람직하다.At this time, a plurality of heat dissipation fins are installed on the outer surface of the copper tube, and the heat dissipation fins and the copper tube are preferably made of gold plating.
이하, 첨부된 도 1 내지 도 3을 참조하여 본 발명의 바람직한 실시예에 따른 습식 발열체에 대해 설명하도록 한다.Hereinafter, a wet heating element according to a preferred embodiment of the present invention will be described with reference to FIGS. 1 to 3.
습식 발열체는 공기를 가열하는 역할과 더불어, 물, 약재 등과 같은 액상을 가열하는 장치로서, 상대적으로 저온인 액상이 발열체에 닿더라도 정온유지의 특성이 있으며, 특히 부식에 대한 방지효과가 탁월한 기술적 특징이 있다.A wet heating element is a device that heats a liquid, such as water and medicine, in addition to heating air, and has a characteristic of maintaining a constant temperature even when a relatively low temperature liquid touches the heating element, and in particular, has an excellent anti-corrosion effect. There is this.
습식 발열체는 발열원인 열선(100)과, SUS관(200)과, 동관(300)과, 방열핀(400)을 포함하여 구성된다.The wet heating element includes a heating wire 100, a SUS pipe 200, a copper pipe 300, and a heat dissipation fin 400 that are heat sources.
열선(100)은 전기공급에 의해 발열하는 발열원으로써, 몰리브덴 와이어로 제공된다.The heating wire 100 is a heating source that generates heat by electricity supply and is provided as molybdenum wire.
몰리브덴 와이어로 제공된 열선(이하 '몰리브덴 열선' 이라 함)은 몰리브덴이 가진 특유의 정온유지 특성에 의해 전기저항이 증가 되거나 감소되는 현상을 스스로 발휘하기 때문에 액상이 발열체에 직분사되더라도 액상의 기화를 위한 온도 유지가 일정하게 유지될 수 있다.The heating wire provided by molybdenum wire (hereinafter referred to as 'molybdenum heating wire') exhibits a phenomenon in which electrical resistance increases or decreases due to the unique constant temperature holding property of molybdenum. The temperature maintenance can be kept constant.
즉, 발열체에 열접촉되는 액상이 기화되면서 흡수하는 열에너지를 정온특성에 의해 완급조절하면서 능동적으로 소비전력을 증가시키거나 감소시키므로 액상을 일정하게 기화시킬 수 있는 것이다.That is, the liquid phase in thermal contact with the heating element vaporizes the liquid energy in a constant manner by actively increasing or decreasing power consumption while adjusting the thermal energy absorbed by the constant temperature characteristic.
특히, 발열체의 표면 최고온도를 대략 200도로 유지하여 액상의 물질 변화를 최대한 억제할 수 있는 효과가 있다.In particular, it is possible to maintain the maximum temperature of the surface of the heating element to approximately 200 degrees to suppress the material change of the liquid state as much as possible.
다음으로, SUS관(200)은 몰리브덴 열선(100)을 감싸며, 상기 몰리브덴 열선(100)의 높은 발열온도를 통제하여 액상이 접촉되는 발열체 표면을 액상이 기화되기 위한 최적의 온도로 유지시키는 역할을 한다.Next, the SUS tube 200 surrounds the molybdenum heating wire 100 and controls the high heating temperature of the molybdenum heating wire 100 to maintain the heating element surface in contact with the liquid phase at an optimum temperature for vaporizing the liquid phase. do.
즉, 대략 1200도에 이르는 몰리브덴 열선(100)의 과도한 열을 통제하여 열이 외부로 유출되는 것을 최대한 차단하여 저항값을 증가시키므로, 발열량을 낮추어 발열체 표면온도를 200도로 유지시킬 수 있는 것이다.That is, by controlling the excessive heat of the molybdenum heating wire 100 to approximately 1200 degrees to block the outflow of heat to the outside to increase the resistance value, it is possible to maintain the heating element surface temperature 200 degrees by lowering the amount of heat.

다음으로, 동관(300)은 SUS관(200)의 외면에 밀착되어 몰리브덴 열선(100)의 열을 외측으로 전달하는 역할을 한다.Next, the copper pipe 300 is in close contact with the outer surface of the SUS pipe 200 serves to transfer the heat of the molybdenum heating wire 100 to the outside.
이때, 동관(300)의 재질은 동(銅)으로 이루어지며, 액상의 기화를 위해 열제공을 원활하게 하고 SUS관(200) 표면열을 빠르게 흡수하는 작용을 한다.At this time, the material of the copper pipe 300 is made of copper (銅), it serves to facilitate the heat supply for the vaporization of the liquid and quickly absorb the surface heat of the SUS pipe 200.
즉, 동관(300)은 후술하는 방열핀(400)과 함께 외부에 노출된 발열체의 표면이며, 액상이 직접 접촉되는 부위인 것이다.That is, the copper tube 300 is the surface of the heating element exposed to the outside together with the heat radiation fin 400 to be described later, the liquid phase is a portion directly contacted.
이때, 액상이 동관(300)에 지속적으로 접촉되는바, 동관(300)의 부식에 대한 방지는 매우 중요하다.At this time, the liquid phase is in continuous contact with the copper tube 300, the prevention of corrosion of the copper tube 300 is very important.
물론, 부식 방지에 대한 효과가 높은 동 재질을 사용하여 부식을 방지하고는 있지만, 부식 방지에 대한 효과를 극대화하기 위해서 동관(300)의 표면에 금도금을 처리하는 것이 바람직하다.Of course, to prevent corrosion by using a copper material having a high effect on the corrosion protection, it is preferable to treat the gold plating on the surface of the copper tube 300 in order to maximize the effect on the corrosion protection.
다음으로, 방열핀(400)은 열접촉 면적을 확대하기 위한 역할을 하며, 동관(300)의 외면에 복수의 박판으로 설치된다.Next, the heat dissipation fin 400 serves to enlarge the thermal contact area, it is installed in a plurality of thin plates on the outer surface of the copper tube (300).
이때, 방열핀(400)의 재질은 열전도율이 높은 동(銅)으로 제공되며, 부식 방지에 대한 효과를 극대화하기 위하여 동관(300)과 마찬가지로 금도금을 처리하는 것이 바람직하다.At this time, the material of the heat dissipation fin 400 is provided with a high thermal conductivity of copper (,), it is preferable to treat the gold plating like the copper tube 300 in order to maximize the effect on the corrosion protection.
