Description

열교환식 전기온수기.{HEAT EXCHANGE ELECTRICITY WATER HEATER}Heat exchanger electric water heater. {HEAT EXCHANGE ELECTRICITY WATER HEATER}

본 고안은 전기온수기에 관한 것으로서, 특히 열이 최대한으로 이용되면서 열효율을 상승시킨 전기온수기용 열 교환기에 관한 것이다.The present invention relates to an electric water heater, and more particularly, to a heat exchanger for an electric water heater in which the heat efficiency is increased while maximizing the use of heat.

통상적으로 전기온수기는, 모두 열교환방식이 아닌 탱크를 직접 가열하고 가열된 온수를 인출하여 사용하는 압상식을 채택하고 있다. 그러나 상기와 같은 종래방식은 물이 순환되지 않아 쉽게 오염될 수 있으며, 이는 특히 지하수를 사용할 경우 히타에 스케일이 부착되면서 히타가 손상되고 수명을 단축시키는 치명적인 원인이 되기도 한다.In general, the electric water heater adopts a piezoelectric formula in which all of the electric water heaters are not directly heat-exchanged but directly heat the tank and draw out the heated hot water. However, the conventional method as described above can be easily polluted because the water is not circulated, which is a fatal cause of damage to the heater and shortening the life as the scale is attached to the heater, especially when using ground water.

따라서, 본 고안의 목적은 물의 순환이 원활한 열교환 방식을 채택하게 되면서 항상 깨끗한 물을 사용할 수 있는 열교환식 전기온수기를 제공함에 있다.Therefore, an object of the present invention is to provide a heat exchanger type electric water heater that can always use clean water while the water circulation adopts a smooth heat exchange method.

본 고안의 다른 목적은 코일관을 고정시키는 수단이 용접이 아닌 나사 체결방식으로서 분해조립이 용이하고 수리 및 청소가 쉬운 열교환식 전기온수기를 제공함에 있다.Another object of the present invention is to provide a heat exchanger type electric water heater in which the means for fixing the coil pipe is not a welding but a screw fastening method, which is easy to disassemble and repair, and easy to repair and clean.

이하 본 고안의 바람직한 실시예를 첨부된 도면을 참조하여 상세히 설명한다. 우선, 본 고안을 설명함에 있어서, 관련된 공지기능 혹은 구성에 대한 구체적인 설명이 본 고안의 요지를 흐트릴 수 있는 경우 그 상세한 설명을 생략한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. First, in describing the present invention, if a detailed description of a related known function or configuration may obscure the subject matter of the present invention, the detailed description thereof will be omitted.

제1도는 본 고안의 바람직한 일실시예에 따른 전기온수기용 열교환기의 내부구조를 보인 중앙 단면도로서, 상/하측커버에 의해 내부 밀폐공간을 형성하는 케이스(10)와, 상기 케이스의 내부에서 주입된 냉수를 온수로 변환시키는 코일관(20)과, 상기 코일관(20)을 고정시켜주는 고정체(30,30')로 조립되어 본체(1)가 형성된다.1 is a central cross-sectional view showing an internal structure of a heat exchanger for an electric water heater according to a preferred embodiment of the present invention, the case 10 forming an inner sealed space by an upper / lower cover, and an injection in the case The main body 1 is formed by assembling a coil tube 20 for converting the cold water into hot water, and fixed bodies 30 and 30 'fixing the coil tube 20.

위를 더욱 자세하게 설명하면 먼저, 원통형의 케이스(10) 내부에는 우레탄폼, 석면 등의 단열재(11)가 삽입된 것으로 상부와 하부에는, 상측커버(16) 및 하측커버(19)가 밀폐 고정되는데, 상기 상측커버의 중앙에 과압방지변(17)이 부착되어 있다. 그리고 상기 케이스(10)의 일측으로, 열매체주입구(12) 및 열매체배출구(14)가 있다. 상기 열매체주입구(12)를 통해 본체(1) 내부로 주입되는 열매체로는 외부에서 히팅장치에 의해 고온으로 가열된 공기가 주입되고, 열매체배출구(14)를 통해 외부로 배출된다. 여기서 상기 히팅장치는 가열실 내로 전기히터가 삽입된 통상의 것으로 도면에 생략된다.In more detail above, first, the insulating material 11 such as urethane foam and asbestos is inserted into the cylindrical case 10, and the upper cover 16 and the lower cover 19 are hermetically fixed to the upper and lower portions thereof. The overpressure preventing side 17 is attached to the center of the upper cover. And one side of the case 10, there is a heat medium inlet 12 and the heat medium outlet (14). As the heat medium injected into the main body 1 through the heat medium inlet 12, air heated to a high temperature by a heating apparatus is injected from the outside, and discharged to the outside through the heat medium outlet 14. Here, the heating apparatus is omitted in the drawings as a conventional electric heater is inserted into the heating chamber.

그리고, 상기 케이스(10)의 내부로는 코일식으로 감기면서 전체적으로 원통형상으로 된 코일관(20)이 삽입되며, 코일관의 하단부는 케이스(10)의 하부로 빠져나가게 되면서 냉수가 공급되는 인 라인(In-line)(24)을 형성하게 되고, 상단부는 역시 케이스(10)의 상부로 빠져나가게 되면서 상기 냉수가 열교환된 온수를 유출시키는 아웃 라인(22)을 형성하게 된다. 여기서 상기 코일관(20)의 양측으로는 내, 외측의 고정체(30,30')가 조립되면서 코일관(20)을 고정시켜 주는데, 상기 양 고정체(30,30')는 제2도에서와 같이 사각으로 된 봉체의 일측면에 반원홈(3l,31')이 일정한 간격을 유지하며 연속적으로 배치된다. 그리고 상기 고정체의 상부와 하부 그리고 중간부에는 구멍(30a)을 두고 코일관(20)의 내측과 외측으로 부착되면서 볼트(34)를 끼워 너트(36)로 체결한다. 이와 같이 마주보는 한 쌍의 고정체(30,30')는 각 반원홈(31,31')이 마주보면서 구멍을 형성하게 될 때 코일관이 끼워져 고정되게 된다. 그리고 상기 내측의 고정체(30)의 외측면에는 케이스(10)의 내벽에 고정된 지지물(32)이 상기 볼트(34)와 너트(36)의 체결시 같이 고정된다. 바람직하게는 상기 지지물(32)은 케이스와 코일관 사이가 간격을 가질 수 있도록 상/하 단부가 굴곡되어 있고, 외측단부는 나사조립 및 용접으로 케이스의 내벽에 부착된다.In addition, the inside of the case 10 is wound into a coil type while the coil tube 20 having an overall cylindrical shape is inserted, and the lower end portion of the coil tube is discharged to the lower portion of the case 10 to be supplied with cold water. The in-line 24 is formed, and the upper end portion is also drawn out to the upper portion of the case 10, thereby forming an outline 22 for flowing out the hot water in which the cold water is heat-exchanged. Here, both sides of the coil tube 20 fix the coil tube 20 while the inner and outer fixing bodies 30 and 30 'are assembled, and both fixing bodies 30 and 30' are shown in FIG. As in the semi-circular grooves (3l, 31 ') on one side of the rectangular rod body is continuously arranged at a constant interval. In addition, the upper and lower parts and the middle part of the fixing body have holes 30a and are attached to the inside and the outside of the coil tube 20, and the bolts 34 are fitted to the nut 36. As described above, the pair of fixtures 30 and 30 'face each other when the semicircular grooves 31 and 31' face each other to form a hole. In addition, a support 32 fixed to an inner wall of the case 10 is fixed to the outer surface of the inner fixing body 30 when the bolt 34 and the nut 36 are fastened together. Preferably, the support 32 is bent in the upper and lower ends so that the space between the case and the coil tube, the outer end is attached to the inner wall of the case by screwing and welding.

이와 같이 구성된 본 고안 전기온수기의 작동상태를 설명하면 다음과 같다.Referring to the operating state of the inventive electric water heater configured as described above are as follows.

외부의 히팅장치에서 가열된 고온의 공기가 본체(1)의 열매체주입구(12)를 통해 케이스(10)내부로 주입되게 되고, 또한 코일관(20)의 인 라인(24)으로 냉수가 공급되게 되면 상기 열매체와 냉수는 서로 열교환하게 되면서 냉수가 온수로 되어 필요에 따라 아웃 라인(22)으로 토출되게 된다. 이때 케이스(10) 내부의 열매체가 압력이 상승하게 되면 상부의 과압방지변으로 유출되어 안전하다.The hot air heated by the external heating device is injected into the case 10 through the heat medium inlet 12 of the main body 1, and the cold water is supplied to the in line 24 of the coil pipe 20. When the heat medium and the cold water exchange heat with each other, the cold water becomes hot water and is discharged to the outline 22 as necessary. At this time, if the heat medium inside the case 10 rises in pressure, it is safe to leak to the overpressure preventing valve in the upper portion.

이상으로 살펴본 바와 같이, 본 고안은 열교환기 내부로 투입된 물이 한곳에서 머물지 않고 순차적으로 이동되면서 가열되어 유출되는 것으로, 변질되거나 오염되는 일이 없고 항상 깨끗한 온수를 사용할 수 있게 된다. 그리고 본체 내부에 있는 코일관을 고정시키는 수단이 견고하고 분해 조립이 쉽게 되면서 청소 및 수리가 용이한 효과가 있다.As described above, the present invention is that the water introduced into the heat exchanger is heated and flowed out while staying in one place, without being deteriorated or contaminated, so that clean hot water can always be used. And the means for fixing the coil tube inside the main body is robust and easy to disassemble and assembly, there is an effect of easy cleaning and repair.
