이하, 첨부한 도면을 통하여 본 발명의 구성을 좀더 상세히 설명한다.Hereinafter, the configuration of the present invention through the accompanying drawings in more detail.

도1은 본 발명의 열교환기능을 갖는 전기온수기의 바람직한 제1실시예를 나타낸 단면도이다.1 is a cross-sectional view showing a first preferred embodiment of an electric water heater having a heat exchange function of the present invention.

도면에 나타낸 바와 같이, 본 발명의 바람직한 제1실시예의 전기온수기는, 온수배출관(10), 전기발열체(11) 및 냉수유입관(12)이 설치되고 축열재(13)가 저장되는 원통형의 밀폐된 내통(6)과, 상기 내통(6)의 외측에 소정의 단열층(15)을 갖고 씌워지는 케이스(5)를 갖는 전기온수기(1)에 있어서, 상기 축열재(13)가 저장된 내통(6)내에 1 이상의 열교환파이프(9)를 수직방향으로 관통되게 구성시킨 것을 특징으로 한다.As shown in the figure, the electric water heater of the first preferred embodiment of the present invention, the hot water discharge pipe 10, the electric heating element 11 and the cold water inlet pipe 12 is installed, the cylindrical seal in which the heat storage material 13 is stored An inner water heater (6) in which the heat storage material (13) is stored in the electric water heater (1) having an inner cylinder (6) that has been formed and a case (5) covered with a predetermined heat insulating layer (15) on the outer side of the inner cylinder (6). It is characterized in that one or more heat exchange pipes (9) are configured to penetrate in the vertical direction.

여기서, 상기 전기온수기(1) 내통(6)의 내부에는, 내통(6)의 상부면까지 근 접하는 길이가 긴 온수배출관(10), 축열재(13)를 가열하는 전기발열체(11) 및 냉수유입관(12)을 구비하고 있으며, 축열재(13)(예로서 물)가 충진되어 있다.Here, the inside of the inner water heater (6) of the electric water heater (1), the length of the hot water discharge pipe 10 is close to the upper surface of the inner cylinder 6, the electric heating element (11) for heating the heat storage material (13) and cold water. The inflow pipe 12 is provided and the heat storage material 13 (for example, water) is filled.

본 발명의 특징인 열교환파이프(9)는 내부가 비어 있는 원통형 파이프 형상으로서 케이스(5) 및 내통(6)에 대하여 수직으로 관통하되, 내통(6)에 충진된 축열재(13) 사이를 통과한다.The heat exchange pipe 9 of the present invention has a cylindrical pipe shape with an empty inside, penetrates perpendicularly to the case 5 and the inner cylinder 6, and passes between the heat storage material 13 filled in the inner cylinder 6. do.

또한, 열교환파이프(9)의 상부(8)에는 필요시(열교환이 불필요시) 상부(8)를 밀폐시킬 수 있는 캡(7)이 형성되며, 상기 열교환파이프(9)는 1 이상의 복수설치가 가능하며, 수직은 물론 수평으로 열교환파이프(9)를 설치할 수 있는 것으로, 이는 본 발명으로부터 용이하게 변형시켜 실시할 수 있다.In addition, the upper part 8 of the heat exchange pipe 9 is provided with a cap 7 capable of sealing the upper part 8 when necessary (when heat exchange is not necessary). It is possible to install the heat exchange pipe 9 vertically as well as horizontally, which can be easily modified from the present invention.

이하, 상기 구성의 본 발명의 바람직한 제1실시예의 열교환기능을 갖는 전기온수기(1)의 작동과정을 설명한다.Hereinafter, an operation process of the electric water heater 1 having a heat exchange function according to the first embodiment of the present invention having the above configuration will be described.

우선, 외부의 냉수가 냉수유입관(12)을 통해 내통(6)으로 유입되게 되면 전기발열체(11)에 의해 가열되고, 데워진 온수는 내통(6)의 상부쪽에 입구를 형성한 온수배출관(10)을 통해 외부로 배출되는 과정은 통상의 전기온수기에서와 같다.First, when the external cold water is introduced into the inner cylinder (6) through the cold water inlet tube 12 is heated by the electric heating element (11), the warmed hot water discharge pipe 10 having an inlet formed on the upper side of the inner cylinder (6) The discharge process to the outside through) is the same as in a conventional electric water heater.

이와 같이 본 발명의 열교환기능을 갖는 전기온수기(1)가 작동하게 되면, 냉수유입관(12)을 통해 내통(6)내로 유입된 물은 소정의 온도로 따뜻히 덥혀지고, 필요시 사용자는 온수배출관(10)을 통해 따뜻한 물을 공급받아 원하는 용도로 사용하면 된다.As such, when the electric water heater 1 having the heat exchange function of the present invention is operated, the water introduced into the inner cylinder 6 through the cold water inlet pipe 12 is warmed to a predetermined temperature, and the user may The warm water is supplied through the discharge pipe 10 and may be used for a desired purpose.

한편, 본 발명의 열교환기능을 갖는 전기온수기(1)에는 상,하 관통의 열교환파이프(9)가 설치되어 있기 때문에, 추운 동절기에 있어서는 상부에 설치된 캡(7) 을 빼내게 되면, 실내의 차가운 공기가 열교환파이프 하부(8') 및 열교환파이프(9)의 내부를 거쳐 따뜻해진 후, 상부(8)를 통해 실내로 공급되는 것이다.On the other hand, since the heat exchanger pipe 9 of the upper and lower penetrations is installed in the electric water heater 1 having the heat exchange function of the present invention, when the cap 7 installed at the upper part is taken out during the cold winter season, The air is warmed through the inside of the heat exchange pipe bottom 8 ′ and the heat exchange pipe 9, and then supplied to the room through the top 8.

이와 같이 실내의 찬공기가 열교환파이프 상부(8)를 통해 더운 공기로서 외부로 배출됨으로써, 차가운 실내는 자연대류현상으로 보온상태에 놓이게 되는 것으로, 열교환기능을 갖는 전기온수기(1)가 설치된 좁은 공간의 화장실이나 세면장, 소규모 샤워장 등의 실내를 보온시킴으로써, 실내에 설치된 상,하수관 등의 동파발생을 최소화시킬 수 있는 것이다.In this way, the cold air in the room is discharged to the outside as hot air through the upper part of the heat exchange pipe 8, so that the cold room is kept warm by natural convection, and a narrow space in which the electric water heater 1 having a heat exchange function is installed. By warming the room, such as toilets, washrooms, small showers, it is possible to minimize the occurrence of freezing, such as water and sewage pipes installed in the room.

예컨대 상기 열교환기능을 갖는 전기온수기(1) 내통(6)의 축열재(13)의 온도가 80℃이상이고, 본 발명의 전기온수기(1)가 설치된 실내의 온도가 5℃라고 가정했을 때, 상기 축열재(13)와 접하고 있는 열교환파이프(9)와 실내의 온도차가 상당히 크기 때문에, 축열재(13)에 의해 데워진 열교환파이프(9) 내부의 공기는 체적이 늘어나게 되면서, 자연적으로 밑에서 위로 상승하게 되어 열교환파이프 선단부(8)를 통해 외부로 배출되어 열교환이 이루어 지므로, 차가운 실내의 공기는 자연대류를 일으켜 실내의 기온이 상승하게 되는 것이다.For example, when the temperature of the heat storage material 13 of the inner water heater 6 of the electric water heater 1 having the heat exchange function is 80 ° C. or higher, and the temperature of the room where the electric water heater 1 of the present invention is installed is 5 ° C., Since the temperature difference between the heat exchange pipe 9 in contact with the heat storage material 13 and the room is considerably large, the air inside the heat exchange pipe 9 heated by the heat storage material 13 increases in volume, and naturally rises from the bottom up. Since the heat exchange is discharged to the outside through the heat exchange pipe front end (8), the heat in the cold room causes natural convection to increase the temperature in the room.

한편, 상기 열교환기능을 갖는 전기온수기(1)는 원통형의 밀폐된 구조로 설명하고 있으나, 경우에 따라서는 상부에 뚜껑을 두어 개폐할 수 있도록 하여 청소 및 수리를 쉽게 할 수 있도록 구성할 수 있다.On the other hand, the electric water heater 1 having the heat exchange function has been described as a cylindrical closed structure, but in some cases it can be configured to be easy to clean and repair by opening and closing the lid on the top.

또한, 수직방향으로 장착된 상기 열교환파이프(9)는 수직으로 복수개 혹은 수평으로도 복수개 설치하여(예컨대 +자형, T자형) 열교환의 효과를 높일 수도 있다.In addition, the heat exchange pipe 9 mounted in the vertical direction may be provided in a plurality of vertically or a plurality of horizontally (for example, + -shaped, T-shaped) to enhance the effect of heat exchange.

또한, 상기 기능성 전기온수기(1)의 형상에 있어서도, 배치장소나 환경에 따라 다각형 등 여러가지 형상으로 구성할 수 있으며, 필요에 따라서는 상기 열교환파이프 하부(8') 부근에 소형의 송풍팬을 설치하여, 외부의 찬 공기를 강제로 유입시키고 가열시켜, 열교환파이프 상부(8)를 통해 강제로 열교환이 이루어 지도록 하는 구성도 가능하다.In addition, in the shape of the functional electric water heater 1, it can be configured in various shapes such as polygons according to the placement location and environment, and if necessary, a small blower fan is installed near the lower portion 8 'of the heat exchange pipe. Thus, it is also possible to forcibly introduce external cold air and heat it so that the heat exchange is forced through the heat exchange pipe upper part 8.

도2는 본 발명의 다른 제2실시예를 나타낸 전기온수기의 단면도로서, 상기 도1의 예와 다른 점은 열교환파이프(9) 대신에 순환관(27)을 설치한 점이 특징이다.FIG. 2 is a cross-sectional view of an electric water heater showing another second embodiment of the present invention, which is different from the example of FIG. 1 in that a circulation pipe 27 is provided instead of the heat exchange pipe 9.

즉, 상기 도1의 예에서와 같이, 도2의 예는 온수배출관(30), 전기발열체(31) 및 냉수유입관(32)이 설치되고 축열재(33)가 저장되는 원통형의 밀폐된 내통(26)과, 상기 내통(26)의 외측에 소정의 단열층(35)을 갖고 씌워지는 케이스(25)를 갖춘 전기온수기(21)에 있어서, 상기 케이스(25)의 외측으로 축열재(33)가 흐를 수 있는 순환관(27)을 돌출되게 장착하고 있다.That is, as in the example of FIG. 1, the example of FIG. 2 is a cylindrical sealed inner cylinder in which the hot water discharge pipe 30, the electric heating element 31, and the cold water inlet pipe 32 are installed and the heat storage material 33 is stored. (26) and the electric water heater (21) provided with a case (25) covered with a predetermined heat insulating layer (35) on the outside of the inner cylinder (26), the heat storage material (33) outward of the case (25). The circulation pipe 27 which can flow is mounted protrudingly.

따라서, 상기 전기온수기(21)를 사용하기 위해 온수밸브(도시 생략)를 열면, 온수는 온수배출관(30)을 통해 외부로 배출되게 된다.Therefore, when the hot water valve (not shown) is opened to use the electric water heater 21, the hot water is discharged to the outside through the hot water discharge pipe (30).

또한, 내통(26)의 축열재(33)가 가열되면 축열재(33)는 순환관(27)을 통해 연속 순환이 이루어 지는데, 축열재(33)는 순환관(27)의 하부에서 상부로 순환, 이동하면서 실내의 공기를 데워주게 되고, 보온이 필요 없는 경우에는 밸브(28)를 잠그어 순수한 전기온수기(21)로서만 사용할 수 있는 것으로, 이와 같은 구성으로 열교환기능을 갖는 전기온수기가 되는 것이다.In addition, when the heat storage material 33 of the inner cylinder 26 is heated, the heat storage material 33 is continuously circulated through the circulation pipe 27, and the heat storage material 33 is from the bottom of the circulation pipe 27 to the top. When circulating and moving, the air in the room is warmed, and when warming is not necessary, the valve 28 is closed and can be used only as a pure electric water heater 21. In this configuration, the electric water heater having a heat exchange function is provided. will be.

또한, 도3은 본 발명의 또 다른 제3실시예를 나타낸 전기온수기의 단면도로서, 온수배출관(50), 전기발열체(51) 및 냉수유입관(52)이 설치되고 축열재(53)가 저장되는 원통형의 밀폐된 내통(46)과, 상기 내통(46)의 외측에 소정의 단열층(55)을 갖고 씌워지는 케이스(45)를 갖춘 전기온수기(41)에 있어서, 상기 전기온수기(41)의 상부에 내통(46)측으로 홈(48)을 형성하고, 상기 홈(48)내에 방열판(47)을 끼워 설치한 구성이다.3 is a cross-sectional view of an electric water heater showing another third embodiment of the present invention, wherein the hot water discharge pipe 50, the electric heating element 51 and the cold water inlet pipe 52 are installed and the heat storage material 53 is stored. An electric water heater (41) having a cylindrical sealed inner cylinder (46) and a case (45) covered with a predetermined heat insulating layer (55) on the outside of the inner cylinder (46). The groove 48 is formed on the inner cylinder 46 side in the upper portion, and the heat sink 47 is fitted into the groove 48.

따라서, 상기 전기온수기(41)가 작동하게 되면, 내통(46)에 가열된 축열재(53)의 열기가 방열판(47)으로 전달되고, 그 열기는 상기 방열판(47)으로부터 외부로 발산되어 실내를 보온할 수 있는 것으로, 이와 같이 함으로써, 열교환기능을 갖는 전기온수기 역할을 하는 것이다.Therefore, when the electric water heater 41 is operated, the heat of the heat storage material 53 heated in the inner cylinder 46 is transmitted to the heat sink 47, the heat is emitted from the heat sink 47 to the outside to the room It is to be able to insulate, by doing so, serves as an electric water heater having a heat exchange function.
