본 고안은 순간온수기에 관한 것으로 특히 절연히터가 내장된 전열부에서 내부로 유입된 물을 순간적으로 가열하는 한편 가열된 물은 감압탱크를 거쳐 외부로 배출하도록 된 것이다.The present invention relates to an instantaneous water heater, and in particular, it is to instantaneously heat the water introduced into the heat transfer unit in which the insulation heater is built, while the heated water is discharged to the outside through the decompression tank.

순간온수기는 그 용량 또는 가열방식에 따라 여러가지가 있으나 본 고안에서 관계하는 순간온수기는 특히 온수세정기 등에 채용되는 비교적 용량이 적은 간이형으로 통상 버너 등으로 가열되는 열교환장치를 구비한 대형의 것과는 달리 상기의 소형 순간온수기에서는 그 가열원으로 전기저항을 이용한 방식이 대부분이며 이는 전열히터를 송수관 외부에 설치하는 것과 히터를 수로에 직접 노출시키는 것으로 대별할 수 있다.Instantaneous water heaters are various according to their capacity or heating method, but the instantaneous water heaters related to the present invention are relatively simple, small capacity, especially used in hot water cleaners, and the like. In the small instantaneous water heater, most of them use electric resistance as the heating source, which can be classified into installing the electric heater outside the water pipe and directly exposing the heater to the water channel.

상기에서 송수관 외부에 히터를 설치한 것은 도전체의 송수관 외주에 전열선을 감아 전열선의 열과 송수관의 저항열로 하여금 송수관 내부의 물을 순간적으로 가온하게끔 한 것이지만 송수관과 전열선의 발열이 송수관 내부에 모두 투여되지 않고 외부로 발산되는 폐열이 많기 때문에 열효율이 그다지 좋지 않은 문제가 있으며 미세한 전류이기는 하지만 누전이 발생하여 전력 손실 및 감전의 우려가 있다.In the above, the heater is installed outside the water pipe to wrap the heating wire on the outer circumference of the conductor so that the heat of the heating wire and the resistance heat of the water pipe cause the water inside the water pipe to be instantaneously heated, but the heat of the water pipe and the heating wire is administered to the inside of the water pipe. There is a problem that thermal efficiency is not very good because there is a lot of waste heat radiated to the outside and there is a risk of power loss and electric shock due to a short circuit occurs even though a minute current.

한편 히터를 송수 경로내에 설치하는 방식은 절연히터를 쓰는 것과 절연하지 않은 히터를 쓰는 것으로 나눌 수 있는 바 절연하지 않은 노출히터를 쓰는 것은 누전이 발생하므로 이에 대한 대응책으로 접지단자를 설치해야 하는 등 번거로운 경향이 있는 반면에 절연히터를 사용하면 누전에 대한 염려는 없게 된다.On the other hand, the method of installing the heater in the water supply path can be divided into the use of an insulated heater and the non-insulated heater. The use of an uninsulated exposed heater causes a short circuit. Therefore, it is cumbersome to install a ground terminal as a countermeasure. While there is a tendency to use insulation heaters, there is no risk of leakage.

상기에서 히터에 접촉되는 물은 급격히 온도가 상승하면서 분자활동이 활발해지며 압력이 상승하고 유속이 빨라지게 되기 때문에 종래에 있어서 히터를 경유하기 전의 수로와 히터 경유후의 수로내의 유속 및 압력을 일정하게 하기 위해 지그재그로 된 미로형 수로를 히터 전후에 형성하여 감압 및 감속을 도모하였다. 따라서 내부구조가 복잡해지고 성형이 어려울 뿐만아니라 순간온수가 사용 후 수로에 남아 있는 물은 온도가 저하되므로 순간온수기 사용 초기에는 냉수가 유출되는 문제가 있으며 별다른 안전장치가 없어 순간 온수가 내부 수로에 물이 공급되지 않을 때 히터가 가동되면 내부 수로가 파손되는 문제가 있다.Since the water in contact with the heater rapidly rises in temperature, molecular activity becomes active, the pressure rises, and the flow velocity becomes faster, so that the flow rate and pressure in the channel before and after the heater are constant in the related art. A zigzag labyrinthic channel was formed before and after the heater to reduce pressure and reduce speed. Therefore, the internal structure is complicated and the molding is difficult, and the water remaining in the waterway after the use of the instantaneous hot water decreases in temperature, so there is a problem that the cold water flows out at the beginning of the instantaneous water heater and there is no safety device. If the heater is operated when this is not supplied, there is a problem that the internal channel is broken.

본 고안은 상기의 문제점을 해결하고자 하는 것이며 따라서 그 목적은 누전 및 감전의 우려를 배제하고 유속과 압력을 일정하게 하는 한편 잔수를 적정온도로 유지하게 하고 내부에 물이 공급되지 않으면 히터가 동작하지 않도록 한 순간온수기를 제공하는 것이다.The present invention is intended to solve the above problems, and therefore its purpose is to eliminate the risk of electric leakage and electric shock, to keep the flow rate and pressure constant, to maintain the residual water at an appropriate temperature, and to prevent the heater from operating unless water is supplied inside. The instant water heater is to be provided.

본 고안은 상기의 목적을 달성하기 위해 갑체와 덮개로 구성되는 순간온수기 몸체 내부를 전열히터가 내장되는 전열부와 감압탱크로 구획하고 감압탱크에는 온도 감지센서와 플로트 스위치 등을 설치하는 것을 특징으로 하며 이하 본 고안을 첨부도면에 도시한 한 실시예를 통하여 더욱 자세히 설명하면 다음과 같다.In order to achieve the above object, the present invention divides the inside of the instantaneous water heater body composed of the body and the cover into a heat transfer unit and a pressure reduction tank in which the heat heater is built, and installs a temperature sensor and a float switch in the pressure reduction tank. Hereinafter, the present invention will be described in more detail with reference to an embodiment shown in the accompanying drawings.

즉, 갑체(11)와 덮개(12)로서 몸체(10)가 구성되며 몸체(10) 내부에 구획판(13)이 형성되어 그 일측에는 절연히터(21)가 내장된 전열부(20)가 마련되고 타측은 온도 감지센서(31) 및 플로트 스위치(32)가 설치된 감압탱크(30)가 마련된다.That is, the body 10 is configured as the body 11 and the cover 12, and the partition plate 13 is formed inside the body 10, and the heat transfer part 20 having the insulation heater 21 therein is formed at one side thereof. The other side is provided with a pressure reduction tank 30 in which a temperature sensor 31 and a float switch 32 are installed.

전열부(20) 하부에는 유입구(14)가 형성되며 구획판(13) 상단부에는 통수공(15)이 형성되고 감압탱크(30) 외측 상단에는 유출구(33a)가 형성된 체크밸브(33)가 설치된다.An inlet 14 is formed in the lower part of the heat transfer part 20, and a through hole 15 is formed in an upper end of the partition plate 13, and a check valve 33 in which an outlet 33 a is formed in an outer upper end of the decompression tank 30 is installed. do.

상기에서 온도 감지센서(31)는 구획판(13)의 통수공(15)에 인근하여 설치되고 플로트 스위치(32)는 감압탱크 내 상단 중앙에 설치되며 온도감지센서(31), 플로트스위치(32), 절연히터(21)는 별도의 전기회로부(미도시)에 각각 회로적으로 접속된다.In the above, the temperature sensor 31 is installed near the water supply hole 15 of the partition plate 13, and the float switch 32 is installed at the upper center of the decompression tank, and the temperature sensor 31, the float switch 32 ), The insulated heater 21 is connected to a separate electric circuit portion (not shown), respectively.

한편 감압탱크(30) 하단에는 배수관(16)이 형성된다.Meanwhile, a drain pipe 16 is formed at the bottom of the decompression tank 30.

도면부호중 미설명부호 33b는 체크밸브(33)의 플런저이고 15는 통수소공이다.Reference numeral 33b in the drawing denotes a plunger of the check valve 33 and 15 represents a water hole.

상기와 같이 구성된 본 고안의 동작을 살펴보면 다음과 같다.Looking at the operation of the present invention configured as described above are as follows.

전열부(20)의 유입구(14) 후방에 설치되는 급수밸브(미도시)를 조작하면 이와 연동하도록된 절연히터(21)에 통전이 되며 유입구(14)를 통해 전열부(20)로 들어온 물은 절연히터(21)의 표면에서 발산되는 열로 급격히 가열되어 구획판(13) 상단의 통수공(15)을 통해 감압탱크(30)로 배출되고 감압탱크(30)에서 유속 및 압력이 안정된 온수는 체크밸브(33)의 플러저(33b)를 밀어 올리고 유출구(33a)를 통해 외부로 배출된다.When a water supply valve (not shown) installed behind the inlet 14 of the heat transfer part 20 is operated, electricity is supplied to the insulation heater 21 interlocked with the water and enters the heat transfer part 20 through the inlet 14. The hot water is rapidly heated by the heat dissipated from the surface of the insulation heater 21 is discharged to the decompression tank 30 through the water hole 15 of the upper end of the partition plate 13 and the water flow rate and pressure in the decompression tank 30 is stable The plunger 33b of the check valve 33 is pushed up and discharged to the outside through the outlet 33a.

상기 과정속에서 온도 감지센서(31)는 구획판(13)의 통수공(15)으로 유입되는 물의 온도를 계속적으로 감지하여 회로적으로 접속된 절연히터(21)를 제어하게 된다.In the process, the temperature sensor 31 continuously detects the temperature of the water flowing into the water passage 15 of the partition plate 13 to control the insulation heater 21 connected to the circuit.

한편 순간온수기의 사용을 중단하고자 급수밸브를 닫으면 유입구(14)로의 물의 공급은 중단되며 체크밸브(33)의 플런저(33b)가 낙하하여 외부로 부터의 역류를 방지하게 된다.On the other hand, when the water supply valve is closed to stop the use of the instant water heater, the supply of water to the inlet 14 is stopped and the plunger 33b of the check valve 33 falls to prevent the reverse flow from the outside.

이때에도 온도감지센서(31)는 감압탱크(30)내의 수온을 계속적으로 감지하게되며 수온이 저하되면 히터(21)를 가동시키게되고 히터(21)의 작동으로 가열된 전열부(20) 내의 물은 구획판(13)의 통수공(15)을 통해 감압탱크(30) 내의 물과 열교환이 이루어지므로 항상 일정온도를 유지하게 되어 순간온수기의 초기 사용시에도 온수를 공급할 수 있게 된다.In this case, the temperature sensor 31 continuously detects the water temperature in the decompression tank 30, and when the water temperature is lowered, activates the heater 21 and the water in the heat transfer part 20 heated by the operation of the heater 21. The heat exchange with water in the decompression tank 30 is made through the water supply hole 15 of the partition plate 13 to maintain a constant temperature at all times, it is possible to supply hot water even during the initial use of the instant water heater.

감압탱크(30)내의 플로트 스위치(32)는 누수 등을 통해 탱크(30)내의 수면이 저하될 경우 동작하여 절연히터(21)의 통전을 막음으로써 내부 수로를 보호하는 것이며 감압탱크(30) 하단의 배수관(16)은 청소 등을 위해 감압탱크(30)내의 물을 교체하고자 할 때 배수를 용이하게 할 수 있도록 한 것이다.The float switch 32 in the decompression tank 30 operates when the water level in the tank 30 decreases due to water leakage, and protects the internal channel by preventing the insulation heater 21 from energizing. The lower end of the decompression tank 30 The drain pipe 16 is to facilitate the drainage when you want to replace the water in the decompression tank 30 for cleaning or the like.

이상에서와 같이 본 고안은 감전 및 누전의 우려가 없는 절연히터(21)를 전열부(20)에 설치하는 한편 감압탱크(30)에는 계속적으로 수온을 감지하여 절연히터(21)를 제어하는 온도감지센서(31)와 감압탱크(30)의 갈수시에 히터(21)의 통전을 방지하는 플로트 스위치(32) 등을 설치한 것으로 순간온수기 사용후 내부에 잔류하는 물을 항상 적정온도로 유지하여 순간온수기 사용 초기에도 온수를 공급하도록 하고 히터(21)를 제어하는 온도감지센서(31)와 플로트 스위치(32)를 통하여 내부 수로를 보호하도록 한 신규 유용의 실용적인 고안인 것이다.As described above, the present invention provides a temperature for controlling the insulation heater 21 by continuously detecting the water temperature in the decompression tank 30 while installing the insulation heater 21 without the risk of electric shock and electric leakage in the heat transfer part 20. The float switch 32 is installed to prevent the heater 21 from energizing when the detection sensor 31 and the decompression tank 30 are drained. The water remaining inside the instantaneous water heater is always maintained at an appropriate temperature. It is a practical design of the new useful to protect the internal waterway through the temperature sensor 31 and the float switch 32 to control the heater 21 to supply hot water even in the initial use of the instantaneous water heater.
