상기 히팅수단(60)은 히팅관(61)과, 이 히팅관(61)의 일측부에 서로 연통되 게 구비되는 연결관(64)과, 상기 히팅관(61)의 양단부에 설치되어 상기 히팅관(61)의 내부에 설치되는 히터(65)로 이루어진다.The heating means 60 is a heating pipe 61, the connecting pipe 64 is provided to be in communication with each other on one side of the heating pipe 61, and is installed at both ends of the heating pipe 61 and the heating It consists of a heater 65 installed in the inside of the pipe 61.

상기 히팅관(61)은 ' ⊃ ' 자 형상을 가지며, 상기 지지프레임(20)의 양측에 체결되어 일정간격을 두고 복수개 직렬로 구비된다.The heating tube 61 has a '⊃' shape, is fastened to both sides of the support frame 20 is provided in plurality in series with a predetermined interval.

그리고 상기 히팅관(61)은 관체 형상을 가지며, 수평방향으로 400∼800mm로 구비되는 수평관부(62)와, 이 수평관부(62)에서 절곡된 벤딩부(63)로 이루어진다.The heating tube 61 has a tubular shape, and consists of a horizontal tube portion 62 provided in a horizontal direction of 400 to 800 mm, and a bending portion 63 bent from the horizontal tube portion 62.

상기 벤딩부(63)는 180°로 절곡되어 물의 흐름이 자연스럽게 유도하게 된다.The bending portion 63 is bent at 180 ° so that the flow of water is naturally induced.

상기 수평관부(62)의 일측단은 히터(65)에 플랜지 결합가능하게 구비되는 것이 바람직하다.One side end of the horizontal pipe portion 62 is preferably provided to be flange coupled to the heater (65).

상기 연결관(64)은 히팅관(61)과 동일한 내경을 가지며, 상기 히팅관(61)의 일측부에 연결되어 물이 지그재그로 순환되도록 유도한다.The connecting pipe 64 has the same inner diameter as the heating pipe 61 and is connected to one side of the heating pipe 61 to induce water to circulate in a zigzag.

상기 히터(65)는 외부에서 전원을 인가받아 열을 발생하는 히팅봉(66)이 구비된다.The heater 65 is provided with a heating rod 66 for generating heat by receiving power from the outside.

As such, the heat exchanging is performed in the optimized state of heat generation and water of the heating rod 61, thereby increasing the overall heat exchange efficiency. In other words, as shown in FIG. 3, when the distance between the horizontal pipe part 41 and the heating rod 61 is 5 mm or less, a space through which water can pass is narrow, and water passes through a lot of effects of friction. When the horizontal pipe part 41 and the heating rod 61 are 20 mm or more, water passing through the heating rod 61 passes through the heating rod 61 without being evenly contacted, and thus it is difficult to maximize heat exchange efficiency. There is a point.
An injection tube 40 for supplying water is installed between the water tank 30 and the heating means 60. Thus, the one injection pipe 40 is provided to supply water in two directions, and the heating means 60 are respectively installed in the injection pipe 40 has a parallel structure as a whole.

At the same time, the heater 65 is provided in a state of being heated to a predetermined temperature by receiving power from the outside. As such, the first heating is performed by contacting the surface of the heating rod 66 which is heated while passing water between the horizontal pipe portion 62 and the heating rod 66 provided on the lower side, and then the bending portion 63. Water is passed between another horizontal tube portion 62 and the heating rod 66 having the same structure through the secondary heating is a zigzag material along the heating tube 61 and the connecting tube 64 As water is circulated, heating is performed sequentially by the heater 65 installed in the heating tube 61.
