종래의 전기보일러의 용수 가온방식은 주로 시즈히터, 석영관히터, 저온용발열히터를 사용한 제품들이 알려져 있다.The water heating method of the conventional electric boiler is known products mainly using the siege heater, quartz tube heater, low-temperature heating heater.

이러한 히터를 사용한 전기보일러는 급수관에서 유입되는 용수를 별도의 물탱크에 저장하고 히터로 일정온도를 유지하여 온도가 상승되면 순환 펌프를 이용하여 순환토록 한 방식이다.The electric boiler using the heater is a way to store the water flowing from the water supply pipe in a separate water tank and maintain a constant temperature as a heater to circulate using a circulation pump when the temperature rises.

본 발명에서 제공하는 순간 가열식 전기보일러용 히팅장치는 상기와 같은 목적을 달성하기 위해 도 1내지 도 4에서 보는 바와 같이 전기보일러(1)를 구성하는 케이싱(2) 내부에 다수개의 열교환기(3)를 횡방향 및 종방향으로 다수개 급수관(4)과 연통되도록 지그재그 상으로 연결 배관하여 펌프(P)와 연결토록 한다. 도시한 도 1에서는 횡방향으로 열교환기(3)를 5개 설치하고, 종방향으로 총 10단으로 설치하여 50개의 열교환기(3)를 하나의 전기보일러(1)에 설치한 경우를 예시하고 있으나, 이는 전기보일러(1)의 용량 등에 따라 가변할 수 있음은 물론이다.The heating apparatus for the instantaneous heating electric boiler provided by the present invention is a plurality of heat exchangers (3) inside the casing (2) constituting the electric boiler (1) as shown in Figure 1 to 4 to achieve the above object. ) Is connected to the pump (P) by zigzag connection pipe so as to communicate with a plurality of water supply pipe (4) in the transverse direction and the longitudinal direction. In FIG. 1, five heat exchangers 3 are installed in a transverse direction, and a total of 10 stages are installed in a longitudinal direction, and 50 heat exchangers 3 are installed in one electric boiler 1. However, this may of course vary depending on the capacity of the electric boiler (1).

상기 열교환기(3)는 알루미늄(Al)과 같은 열전도성이 우수한 재질로 하우징(3a)을 제작토록 하며, 상부가 개방된 내부에 다수의 원형봉(3b)을 형성하여 하우징(3a)의 일측 유입공(3c)으로 유입된 용수가 원형봉(3b) 사이를 경유하면서 와류를 일으키면서 오랫동안 하우징(3a) 내부에서 머물렀다가 타측 유출공(3d)으로 유출되도록 구성한다.The heat exchanger (3) allows the housing (3a) to be made of a material having excellent thermal conductivity, such as aluminum (Al), and forms a plurality of circular rods 3b in an open top portion of the housing 3a. The water flowing into the inflow hole (3c) is configured to stay inside the housing (3a) for a long time while causing vortex while passing between the circular rods (3b) to flow out to the other outlet hole (3d).

그리고 열교환기(3)의 하우징(3a) 개방부에는 히팅수단(5)을 결합볼트(6) 등을 사용하여 고정시키도록 한다.The heating means 5 is fixed to the opening of the housing 3a of the heat exchanger 3 using a coupling bolt 6 or the like.

상기 히팅수단(5)은 하우징(3a) 내부를 통과하는 용수를 가온할 수 있도록 스틸(steel), 세라믹(ceramic) 등의 다양한 재질로 제작된 기판(5a) 상부에 실크스크린 인쇄기법을 적용하여 절연체(5b) 및 도체(5c), 그리고 상기 도체(5c) 사이에 다수개의 저항(5d)을 등간격으로 프린팅 한 후 보호막(5e)을 프린팅토록 하며, 기판(5a)의 하부에는 테프론(5f)을 코팅한 것이다.The heating means 5 applies a silkscreen printing method to the upper portion of the substrate 5a made of various materials such as steel, ceramic, etc. to heat the water passing through the housing 3a. After printing a plurality of resistors 5d between the insulator 5b and the conductor 5c and the conductor 5c at equal intervals, the protective film 5e is printed, and the lower portion of the substrate 5a has a teflon 5f. ) Is coated.

상기와 같이 구성될 수 있는 본 발명의 순간 가열식 전기보일러용 히팅장치는 전기보일러(1)의 제어반에서 가동 스위치를 ON하면, 펌프(P) 및 히팅수단(3)이 가동되어 용수를 급수관(4)을 통해 다수개의 열교환기(3)로 급수하게 되고, 열교환기(3)를 경유하는 용수는 히팅수단(5)에 의해 순간적으로 가온되는 것으로서, 본 발명의 작용을 이하에 보다 상세히 설명키로 한다.In the heating device for the instantaneous heating electric boiler of the present invention which can be configured as described above, when the movable switch is turned on in the control panel of the electric boiler 1, the pump P and the heating means 3 are operated to supply water to the water supply pipe 4 The water supply to the plurality of heat exchanger (3), and the water passing through the heat exchanger (3) is instantaneously warmed by the heating means (5), the operation of the present invention will be described in more detail below. .

펌프(P)와 급수관(4)을 통해 열교환기(3)의 유입공(3c)으로 유입된 용수는 하우징(3a) 내부에 형성된 다수개의 원형봉(3b)에 의해 와류를 일으키면서 유출공(3d)으로 서서히 유출된다.Water flowed into the inlet hole 3c of the heat exchanger 3 through the pump P and the water supply pipe 4 causes vortex by a plurality of circular rods 3b formed inside the housing 3a, Slowly outflow into 3d).

그로 인해 하우징(3a) 내부로 유입된 용수는 하우징(3a) 내부에서 통과하는 체류시간이 길어져 히팅수단(5)에서 발열되는 열원을 전열받는 시간이 길어지게 되며, 다수개의 원형봉(3b)은 용수가 히팅수단(5)에서 발열되는 열원과 접하는 전열면적도 최대화시켜 전열효과가 극대화될 수 있는 것이다.As a result, the water flowing into the housing 3a has a longer residence time passing through the housing 3a, resulting in a longer time for the heat source to be heated by the heating means 5, and the plurality of circular rods 3b Water can also be maximized by maximizing the heat transfer area in contact with the heat source that generates heat from the heating means (5).

상기 히팅수단(5)은 전원이 도체(5c)에 인가되면 다수개의 저항(5d)에서 열이 발생하여 기판(5a)을 통해 하우징(3a) 내부의 용수에 전열을 행하게 되며, 도체(5c) 및 저항(5d) 등이 보호막(5e)에 의해 공기와 접촉하지 못하므로 산화로 인한 제반 문제점도 일소할 수 있게 되는 것이다.The heating means 5 generates heat from a plurality of resistors 5d when power is applied to the conductor 5c, and heats the water inside the housing 3a through the substrate 5a, and the conductor 5c. And since the resistance 5d and the like do not come into contact with the air by the protective film 5e, all problems due to oxidation can be eliminated.

한편, 본 발명자가 본 발명에 의한 전기보일러를 제작, 가동시켜 시험한 결과 용수가 열교환기(3) 하나를 통과 시 마다 용수(열교환기 하나당 용수량은 ±300㎖)의 온도는 약 0.8℃ 상승하였으며, 열교환기(3)를 50개 연결, 설치하여 용수를 가온하게 되면 분당 30리터의 용수를 Δ40±5℃로 가온할 수 있었으며, 이는 기존 전기보일러에 비해 약 50% 정도 열효율이 우수한 것으로 확인되었다.On the other hand, the inventors fabricated, operated and tested the electric boiler according to the present invention, and the temperature of the water (the amount of water per one heat exchanger was ± 300 ml) rose about 0.8 ° C every time the water passed one heat exchanger (3). When the water was heated by connecting and installing 50 heat exchangers (3), 30 liters of water per minute could be heated to Δ40 ± 5 ℃, which was confirmed to be about 50% more efficient than conventional electric boilers. .

이와 같이 본 발명의 순간 가열식 전기보일러용 히팅장치는 용수를 다수개의 열교환기(3)를 순차적으로 와류를 일으키면서 통과토록 하여 체류시간을 길게 가져갈 수 있고 최대의 전열면적을 확보한 상태에서 열교환기(3)에 설치된 히팅수단(5)이 직접 용수를 가온토록 함으로써 열손실이 없고 열효율이 매우 우수한 것이 다.Thus, the heating device for the instantaneous heating electric boiler of the present invention can pass the water passing through a plurality of heat exchanger (3) in sequence to take a residence time can take a long residence time heat exchanger in a state that secured the maximum heat transfer area The heating means (5) installed in (3) directly heats the water so that there is no heat loss and the thermal efficiency is very excellent.

또한 상기 히팅수단(5)은 제작 시 소성온도가 850° 이므로 850°가 되기 전에는 산화가 되지 않아 그 수명이 반영구적이다.In addition, since the heating means 5 has a calcination temperature of 850 ° during manufacture, the heating means 5 is not oxidized before reaching 850 ° and its life is semi-permanent.

본 발명의 순간 가열식 전기보일러용 히팅장치는 관련산업계에서 접목하여 고효율의 전기보일러를 제작, 보급이 가능한 것이다.Heating device for the instantaneous heating electric boiler of the present invention is to be able to manufacture and disseminate high-efficiency electric boiler by grafting in the related industry.
