본 발명은 전기보일러용 온수가열장치에 관한 것으로, 더욱 상세하게는 물이 접촉되는 면적을 최대화하기 위해 연결관을 중심으로 다수개의 순환관을 방사상으로 형성하여 고온의 열을 신속히 흡수할 수 있고, 온수가 단시간에 식는 것을 방지하기 위해 축열실에 축열볼이 충진되는 축열관을 형성함으로서, 온수가 단시간에 식혀지는 것을 방지할 수 있도록 한 전기보일러용 온수가열장치에 관한 것이다.The present invention relates to a hot water heater for an electric boiler, more specifically, to maximize the area contacted by water to form a plurality of circulation pipes radially around the connecting pipe to quickly absorb high-temperature heat, The present invention relates to a hot water heating device for an electric boiler that prevents hot water from being cooled in a short time by forming a heat storage tube in which a heat storage ball is filled in the heat storage chamber in order to prevent the hot water from being cooled in a short time.

일반적으로 전기보일러의 가열장치로서 물을 가열하는 방은 보일러 본체 내부에 규소 또는 이산화규소를 함유하거나 또는 세라믹 소재로 된 막대형상 또는 코일형상의 발열체를 설치하여 본체 내부를 가열시키고, 본체 내부에 설치된 열교환 파이프로 고온의 열이 전달되도록하여 파이프를 순환하는 물을 가열시킨 후 이송 파이프를 통해 온수탱크로 공급하는 방법과, 온수탱크 내부에 히터가 내장된 발열봉를 삽입하여 물을 직접가열하는 방법이 있다.In general, a room for heating water as a heating device of an electric boiler contains silicon or silicon dioxide or a rod-shaped or coil-shaped heating element made of ceramic material to heat the inside of the main body, and is installed inside the main body. The method of heating the water circulating through the heat exchange pipe to heat the pipe and supplying it to the hot water tank through the transfer pipe, and directly heating the water by inserting a heating rod with a heater inside the hot water tank. have.

그러나, 상기 가열방법에 있어서, 발열체를 가열하여 파이프에 고온의 열을 전달하는 방법은 발열체의 고온이 물에 직접 전달되지 못해 물을 가열속도가 늦어지며, 물이 열교환 파이프를 순환하고 이송 파이프를 경유하면서 열손실이 발생하여 물의 온도가 떨어지게 되는 등 열효율이 저하되는 문제점이 있었다.However, in the heating method, a method of heating the heating element to transfer high temperature heat to the pipe is a high temperature of the heating element is not directly transmitted to the water, so the water heating rate is slowed down, the water circulates the heat exchange pipe and the transfer pipe There was a problem that the thermal efficiency is lowered such that the heat loss occurs while passing through and the temperature of the water drops.

온수탱크에 히터가 내장된 발열봉을 삽입하여 직접 물을 가열시키는 방법은 발열봉이 직접 물과 접촉하여 가열하게 됨으로서 물의 온도를 급속히 상승시킬 수 있는 장점은 있으나, 물의 접촉면적이 원형막대 형상의 발열봉 바깥둘레면에 한정되므로서 대량의 물을 신속히 가열시킬 수 없고, 히터의 작동이 정지되면 가열된 물이 빨리 식게 되는 문제점이 있으며, 고온의 열이 발열봉 외부로 신속히 배출되지 못하여 발열봉 내부의 히터가 고온의 열에 영향을 받아 수명이 단축되는 문제점이 있었다. The method of directly heating the water by inserting a heating rod with a heater in the hot water tank has the advantage that the heating rod can be heated in direct contact with the water, thereby rapidly increasing the temperature of the water. It is limited to the outer circumferential surface of the rod, so that a large amount of water cannot be heated quickly, and when the operation of the heater is stopped, the heated water cools quickly, and high temperature heat is not quickly discharged to the outside of the heating rod. The heater is affected by the heat of the high temperature had a problem that the life is shortened.

본 발명은 상기와 같은 전기보일러의 온수가열장치의 문제점을 해결하기 위해 안출한 것으로, 연결관을 중심으로 다수개의 순환관을 방사상으로 형성하여 가열탱크의 바깥둘레면과 함께 다수개의 순환관 안쪽둘레면으로 물이 접촉되게하여 고온의 열을 신속히 흡수할 수 있도록 하고, 축열실에 축열볼이 충진되는 축열관을 형성함으로서, 전기보일러의 가동중에는 축열볼에 축적된 열이 축열캡의 통공으로 유입되는 물을 가열시키고, 축열볼에 의해 가열된 물은 통공을 통해 배출되도록하며, 전기보일러가 작동타이머에 의해 일정시간 동안 정지되거나 가동을 멈출 때에는 축열된 열을 서서히 발산하면서 온수가 단시간에 식혀지는 것을 방지할 수 있도록 하는 온수가열장치를 제공코져하는 것이다.The present invention has been made to solve the problems of the hot water heating device of the electric boiler as described above, by forming a plurality of circulation pipes radially around the connection pipes and the inner circumference of the plurality of circulation pipes with the outer peripheral surface of the heating tank By contacting water to the surface to quickly absorb high temperature heat, and to form a heat storage tube filled with the heat storage ball in the heat storage chamber, the heat accumulated in the heat storage ball flows into the through hole of the heat storage cap during operation of the electric boiler. The water heated by the heat storage ball is discharged through the through hole, and when the electric boiler is stopped or stopped for a certain time by the operation timer, the hot water cools down in a short time while gradually dissipating the accumulated heat. It is to provide a hot water heating device to prevent it.

It is characterized by consisting of a heater (20) fixedly coupled to (23).

상기와 같이 구성된 본 발명은 온수탱크(40)의 일측 저면에 마련된 플랜지(41)내측으로 가열탱크(10)를 삽입하면서 연결관(14)의 끝부분을 플랜지(41) 입 구측 끝부분에 위치시킨 후 용접고정시키고, 가열탱크(10)의 연결관(14) 입구로 히터(20)를 삽입하면서 고정플레이트(25)가 플랜지(41)에 밀착되도록 한 후 고정볼트(부호생략)로 체결하므로서 설치작업이 완료된다.The present invention configured as described above is positioned at the end of the inlet side of the flange (41) while inserting the heating tank (10) into the inside of the flange 41 provided on one side bottom of the hot water tank (40). After fixing the welding, and inserting the heater 20 into the inlet of the connection pipe 14 of the heating tank 10, the fixing plate 25 is in close contact with the flange 41, and then tightened with a fixing bolt (not shown) The installation is complete.

본 발명의 온수가열장치는 원통체인 온수탱크(40)의 일측 저면에서 중심방향으로 경사지게 설치하는 것이 가장바람직하며, 온수탱크(40)의 저수용량에 따라 수개의 온수가열장치를 병렬장착할 수 있는 것이다.The hot water heating device of the present invention is most preferably installed to be inclined toward the center from the bottom of one side of the hot water tank 40, which is a cylindrical body, and can be mounted several hot water heaters in parallel according to the low capacity of the hot water tank (40) will be.

도면중 미설명부호 28은 가열실(11)의 밀폐를 위한 개스킷이다.In the figure, reference numeral 28 is a gasket for sealing the heating chamber 11.

전기보일러를 가동하면 전력선(29)으로부터 공급된 전류가 단자봉(26)으로 흐르게 되면서 절연관(21)의 바깥둘레에 감겨진 히터코일(22)이 발열하게 되고 진공상태(10-5Torr)의 가열실(11) 온도는 800℃~900℃의 고온을 유지하게 된다.When the electric boiler is operated, the electric current supplied from the power line 29 flows to the terminal rod 26, causing the heater coil 22 wound around the outer tube 21 to generate heat, and in a vacuum state (10 -5 Torr). The heating chamber 11 temperature maintains a high temperature of 800 ° C to 900 ° C.

가열실(11)의 온도가 상승하여 가열탱크(10)가 발열하게 되면, 온수탱크(40)의 물은 가열탱크(10)의 바깥둘레면과 접촉하여 데워짐과 동시에 연결관(14)을 중심으로하여 방사상으로 형성된 다수개의 순환관(12)안쪽둘레면을 접촉, 순환로(13)를 관통하면서 데워지게 된다.When the temperature of the heating chamber 11 rises and the heating tank 10 generates heat, the water of the hot water tank 40 is heated in contact with the outer circumferential surface of the heating tank 10 and at the same time the connection pipe 14 is opened. The inner circumferential surface of the plurality of circulation pipes 12 radially formed as a center is heated while passing through the circulation path 13.

즉, 저온의 물은 가열탱크(10)의 바깥둘레면과 순환관(12)의 안쪽둘레면에서 발산되는 고온의 열을 전달받아 가열되는 것이며, 물이 부분적으로 가열되어 온도가 높아지면 가열된 물은 팽창하여 밀도가 작아지기 때문에 부력이 생겨 위로 올라 가고, 위에 있던 온도가 낮고 밀도가 큰 물이 내려오게 된다.That is, the low-temperature water is heated by receiving high-temperature heat radiated from the outer circumferential surface of the heating tank 10 and the inner circumferential surface of the circulation tube 12, and the water is heated when the water is partially heated to increase the temperature. As the water expands and becomes less dense, buoyancy rises and rises above it, resulting in lower, higher-density water.

상기와 같은 대류현상이 반복되면서 저온의 물은 온수탱크 내부의 위쪽에서부터 고온으로 데워지게 된다.As the above convection phenomenon is repeated, the low temperature water is heated to a high temperature from the inside of the hot water tank.

상기 온수가열과정있어서, 히터(20)에 의해 가열실(11) 내부는 급속하게 가열되어 고온을 유지하게 되는데, 고온의 열을 신속히 발산시키지 못하게 되면 가열실(11) 내부의 절연관(21), 히터코일(22), 연결플레이트(23), 연결봉(24), 단자봉(26) 등으로 구성된 히터(20)의 수명을 단축시키게 된다.In the hot water heating process, the inside of the heating chamber 11 is rapidly heated by the heater 20 to maintain a high temperature. If the high temperature heat cannot be quickly dissipated, the insulating tube 21 inside the heating chamber 11 is heated. , To shorten the life of the heater 20 composed of the heater coil 22, the connecting plate 23, the connecting rod 24, the terminal rod 26 and the like.

본 발명의 온수가열장치는 도 3과 같이 고온의 열을 신속히 발산시킬 수 있도록 연결관(14)을 중심으로하여 다수개의 순환관(12)을 방사상으로 형성하므로서 열의 발산면적을 최대한 넓게 하였다.The hot water heating apparatus of the present invention, as shown in Figure 3 so as to rapidly dissipate high temperature heat by forming a plurality of circulation pipes 12 radially around the connecting pipe 14 to maximize the heat dissipation area as wide as possible.

즉, 가열탱크(10) 바깥둘레면과 함께 다수개의 순환관(12) 안쪽둘레면으로 물이 접촉되게하여 고온의 열을 신속히 흡수할 수 있도록 한 것이다.That is, the water is brought into contact with the inner circumferential surface of the plurality of circulation pipes 12 together with the outer circumferential surface of the heating tank 10 so as to quickly absorb high temperature heat.

한편, 가열실(11) 내부의 열은 히터(20) 내측 중공부에 위치하는 축열관(15)의 축열실(16)내부에 충진된 축열볼(17)에 전달된다.Meanwhile, the heat in the heating chamber 11 is transferred to the heat storage ball 17 filled in the heat storage chamber 16 of the heat storage tube 15 positioned in the hollow inside the heater 20.

축열볼(17)의 재질은 세라믹 또는 청동이나 황동 등의 구리합금을 선택적으로 사용할 수 있으며, 구형으로 제작하는 것이 바람직하다.As the material of the heat storage ball 17, a copper alloy such as ceramic or bronze or brass can be selectively used, and it is preferable that the heat storage ball 17 be manufactured in a spherical shape.

축열볼(17)에 축적된 열은 전기보일러의 가동중에는 축열캡(18)의 통공(19) 으로 유입되는 물을 가열시키고, 축열볼(17)에 의해 가열된 물은 통공(19)을 통해 배출되며, 전기보일러가 작동타이머에 의해 일정시간 동안 정지되거나, 가동을 멈출 때에는 축열된 열을 서서히 발산하면서 온수가 단시간에 식혀지는 것을 방지하게 된다. Heat accumulated in the heat storage ball 17 heats the water flowing into the through hole 19 of the heat storage cap 18 during operation of the electric boiler, and the water heated by the heat storage ball 17 passes through the through hole 19. When the electric boiler is stopped by the operation timer for a predetermined time or stops operation, the hot water is cooled in a short time while gradually dissipating the accumulated heat.

상기 축열캡(18)은 축열실(16)에 축열볼(17)을 충진한 후 스폿용접하여 결합하는 것이다. The heat storage cap 18 is to be bonded by spot welding after filling the heat storage ball 17 in the heat storage chamber (16).

히터(20)의 절연관(21)을 수용하는 관통공(31)이 뚫리고 다수개의 순환관(12)중앙부를 지지고정하는 지지판(30)은 히터(20)의 고열로 인해 순환관(12)이 휘어지거나 가열탱크(10)의 바깥둘레면이 변형되어 히터코일(22)에 접촉되므로서 발생하는 누전현상을 차단할 수 있도록 한 것으로, 가열탱크(10)의 내구성을 높일 수 있도록 한 것이다.The through plate 31 for receiving the insulation tube 21 of the heater 20 is drilled and the support plate 30 for supporting the center of the plurality of circulation tubes 12 is the circulation tube 12 due to the high heat of the heater 20 The outer circumferential surface of the heating tank 10 is bent or deformed to prevent a short circuit caused by contact with the heater coil 22, thereby increasing the durability of the heating tank 10.

이상에서 상세히 살펴본 바와 같이 본 발명은 물이 접촉되는 면적을 최대화하기 위해 연결관(14)을 중심으로 다수개의 순환관(12)을 방사상으로 형성함으로서, 가열탱크(10) 바깥둘레면과 함께 다수개의 순환관(12) 안쪽둘레면으로 물이 접촉되게하여 고온의 열을 신속히 흡수할 수 있게 되고,As described in detail above, the present invention radially forms a plurality of circulation pipes 12 around the connection pipe 14 so as to maximize the area in which water is contacted, thereby providing a plurality of surfaces together with the outer circumferential surface of the heating tank 10. Water is brought into contact with the inner circumferential surface of the two circulation pipes 12 so as to quickly absorb high temperature heat,

온수가 단시간에 식는 것을 방지하기 위해 축열볼(17)이 충진되는 축열실(16)과 축열실(16)의 입구부에 통공(19)이 뚫린 축열캡(18)이 용접결합되는 축열 관(15)을 형성함으로서, 전기보일러의 가동중에는 축열볼(17)에 축적된 열이 축열캡(18)의 통공(19)으로 유입되는 물을 가열시키고, 축열볼(17)에 의해 가열된 물은 통공(19)을 통해 배출되도록하여, 전기보일러가 작동타이머에 의해 일정시간 동안 정지되거나, 가동을 멈출 때에는 축열된 열을 서서히 발산하면서 온수가 단시간에 식혀지는 것을 방지할 수 있게 되어 전기보일러의 온수관리 효율을 높일 수 있는 등 그 기대되는 가치가 매우 우수한 발명이다.In order to prevent the warm water from cooling in a short time, the heat storage tube 16 in which the heat storage ball 17 is filled and the heat storage cap 18 in which the through hole 19 is drilled are connected to the inlet of the heat storage chamber 16. 15), the heat accumulated in the heat storage ball 17 heats the water flowing into the through hole 19 of the heat storage cap 18 during operation of the electric boiler, and the water heated by the heat storage ball 17 By discharging through the through-hole 19, when the electric boiler is stopped for a certain time by the operation timer, or when the operation is stopped, it is possible to prevent the hot water cools in a short time while gradually dissipating the accumulated heat, so that the hot water of the electric boiler It is an invention that is expected to have very high expected value, such as improved management efficiency.
