본 발명은 요식업장 등에서 액상의 물질 예로써 물, 육수, 각종국물 등을 넣어 일정한 온도로 가열 및 보온시키는 전기 온수기에 관한 것으로, 더욱 상세히는 전기장치부를 간단한 구조로 개선시켜 제작성과 사용성이 간편하도록 하고, 히터를 직접 액상의 내용물에 닿지 않도록 내통의 저면판 하부에 설치하여 히터의 과열에 의한 안전사고를 미연에 방지할 수 있도록 함과 동시에 전체적으로는 조립해체가 가능한 구조의 전기 온수기를 제공하고자 함에 목적을 둔 것이다.The present invention relates to an electric water heater that puts water, broth, various broths, etc. as a liquid substance in a food and beverage industry, and heats and warms it to a constant temperature. In order to prevent safety accidents due to overheating of the heater by installing the heater under the bottom plate of the inner cylinder so as not to directly touch the contents of the liquid, and to provide an electric water heater with a structure that can be assembled and disassembled as a whole. It is purpose.

종래 전기 온수기는 도 5 내지 도 7 과 같이 구성되어 있다. 즉, 온수기(1)는 내용물이 저장되는 내통(2)과, 내통(2)을 감싸고 케이스역할을 하는 외통(3)으로 구성되며, 외통(3)의 일측에는 저장된 내용물을 외부로 인출시키기 위한 꼭지(4)와 상기 내용물을 적정한 온도로 제어하기 위한 콘트롤박스(5)가 각각 설치되어 있다.Conventional electric water heaters are configured as shown in Figs. That is, the water heater 1 is composed of an inner cylinder (2) in which the contents are stored, and an outer cylinder (3) surrounding the inner cylinder (2) and serving as a case, and on one side of the outer cylinder (3) for drawing out the stored contents to the outside. Each of the nipple 4 and the control box 5 for controlling the contents at an appropriate temperature is provided.

한편, 이와같이 된 전기 온수기(1)에 있어서의 히터(6)의 설치 구조를 살펴보면, 도 6 및 도 7 과 같이 구성되어 있다.On the other hand, the installation structure of the heater 6 in the electric water heater 1 thus obtained is constructed as shown in Figs. 6 and 7.

도 6 의 구성에 의하면 히터(6)가 내통저면판(2a)의 상부로 돌출되어 내용물과 접촉하도록 구성되어 있는데, 이러한 경우 내용물의 수위가 히터(6) 이하로 떨어질 경우 히터(6)의 과열에 의한 사고가 발생할 우려가 있으며, 히터(6)가 쉽게 부식되는 결함이 있다.According to the configuration of FIG. 6, the heater 6 is configured to protrude to the upper portion of the inner bottom plate 2a to be in contact with the contents. In this case, when the water level of the contents drops below the heater 6, the heater 6 is overheated. There is a risk that an accident may occur, and there is a defect that the heater 6 is easily corroded.

한편, 이와같은 과열에 따른 사고및 히터(6)의 부식을 방지하기 위한 방안으로 도 7 과 같은 구조로 내통저면판(2a)의 상부로 별도의 덮개판(7)을 씌워 공간부(8)를 형성하고 상기한 공간부(8)내에 히터(6)를 설치하여 히터(6)의 부식방지와 과열로 인한 사고를 예방하고 있으나, 덮개판(7) 위에 액상의 내용물이 담겨져 있어 내통 저면판(2a)과 덮개판(7)간의 밀봉이 확실히 되어야하는데 확실한 밀봉을 위해서는 용접을 해야했던 것으로, 결국 별도의 히터 덮개판(7)을 구성하고 또한 밀폐성의 확보를 위한 용접공정이 따르게 되므로 제작 단가의 상승요인을 가져왔던 것이다. 또한 상기 공간부(8)내에 히터(6)가 설치된 구조는 예로써 히터(6)에 고장이 생겼을 경우 해체 및 조립이 불가능하게 구성되어 있어 온수기 자체를 폐기시켜야 하는 문제점 또한 내포하고 있어 극히 비경제적이었다. 그리고 상기한 종래 온수기(1)는 도 5 에서 도시한 바와같이 콘트롤박스(5)가 별도로 구성되어 외통(3)에 돌출된 상태로 결합되어 있고, 또한 그 부피가 크기 때문에 이동운반시 타물체와 부딪혀 콘트롤박스(5)가 손상되는 등 불합리한 요소를 내포하고 있었던 것이다.On the other hand, in order to prevent the accident and the corrosion of the heater (6) due to such overheating as shown in Figure 7 with a separate cover plate 7 to the upper portion of the inner cylinder bottom plate (2a) with a structure as shown in Figure 7 In order to prevent the accident caused by corrosion and overheating of the heater 6 by installing the heater 6 in the above space portion 8, the liquid contents are contained on the cover plate 7 so that the inner cylinder bottom plate is formed.
