본 고안은 온수전용과 온수ㆍ난방 겸용으로 사용할 수 있는 1관 2수식의 순간식 가스보일러에 관한 것으로, 특히 열교환기의 양측에 설치된 급수관과 온수공급관에 난방수 회수관과 난방수 공급관을 각각 병렬로 연결하여, 근본적 기능은 1관 1수식이면서도 난방용 순환수 및 온수공급을 필요한 시점에 간단한 스위치 조작만으로 가능께 하는 1관 2수식의 순간식 가스보일러에 관한 것이다.The present invention relates to a one-pipe two-stage instantaneous gas boiler that can be used for both hot water and hot water / heating. In particular, the heating water recovery pipe and the heating water supply pipe are parallel to the water supply pipe and the hot water supply pipe installed on both sides of the heat exchanger. The basic function is to provide a one-pipe two-stage instantaneous gas boiler that can supply heating circulation water and hot water by simple switch operation when needed.

종래의 1관 2수식의 순간 가스보일러에 있어서는 제1도에 도시한 바와 같이 가스공급관(1)에 가스가 공급되면 이를 매인버어너(5)에서 연소시켜 열교환기(4)를 가열하고, 이에 따라 난방수회수관(13)을 통하여 열교환기(4)에 회수된 난방수는 가열된후 온수열교환기(28)를 통해 난방수공급관(12)으로 공급되고, 또한 이때 급수관(2)으로 급수된 물은 온수열교환기(28)에서 난방수에 의해 가열된 후 온수공급관(3)으로 공급되게 되어 있다. 그러나, 이러한 종래의 장치에 있어서는 온수열교환기(28)를 사용하여 온수를 가열하게 되므로 열효율이 떨어지고, 부피가 커지게 되어 설치면적에 제약을 받게 되고 실비비가 고가로 되는 결점이 있었다.In the conventional one-pipe two-stage instantaneous gas boiler, when gas is supplied to the gas supply pipe 1 as shown in FIG. 1, it is combusted by the main burner 5 to heat the heat exchanger 4, Accordingly, the heating water recovered to the heat exchanger 4 through the heating water recovery pipe 13 is heated and then supplied to the heating water supply pipe 12 through the hot water heat exchanger 28, and at this time, water is supplied to the water supply pipe 2. The heated water is heated by the heating water in the hot water heat exchanger 28 and then supplied to the hot water supply pipe 3. However, in such a conventional apparatus, since the hot water is heated by using the hot water heat exchanger 28, the thermal efficiency decreases, the volume becomes large, the installation area is restricted, and the actual cost ratio is high.

또한, 종래에는 제2도에 도시한 바와같이 급수관(2)은 1개소로 하고, 난방ㆍ온수 변환별브(9)를 통하여 급수관(2)에 직결된 온수공급관(3)이 열교환기(4)의 난방수 내를 통과하게 난방수공급관(12)과 온수공급관(3)을 별도로 구분하고, 공급관(2)이 급수가 없을때는 난방수회수관(13)의 회수난방수가 순환펌프(10)를 통하여 열교환기(4)에 회수되며, 온수를 사용하기 위한 급수가 있을때는 난방수회수관(13)을 차단하게 난방ㆍ온수 변환밸브(9)를 구성하여 온수ㆍ난방 겸용으로 사용하게 하였다. 그러나 이러한 종래의 장치에 있어서는 여름철과 같이 난방을 필요로 하지 않아 온수기을 사용하는 경우에도 난방·온수 변환밸브(9)가 난방수회수관(13)을 차단한 상태에서 열교환기(4)의 난방수는 난방·온수 변환밸브(9)와 순환펌프(10)를 바로 통하여 순환하게 되므로 열효율이 저하되고, 순환펌프(10)의 회전에 따른 동력의 소비가 증가하고, 열교환기(4)의 구조가 복잡하여 제품의 원가가 고가로 되는 결점이 있었다.In addition, in the related art, as shown in FIG. 2, the water supply pipe 2 has one place, and the hot water supply pipe 3 directly connected to the water supply pipe 2 through the heating / hot water conversion separation valve 9 is a heat exchanger 4. Separate the heating water supply pipe 12 and the hot water supply pipe (3) so as to pass through the heating water of the, and when the supply pipe (2) there is no water supply, the recovered heating water of the heating water recovery pipe (13) to the circulation pump (10) When the water is recovered through the heat exchanger 4 and there is water supply for using hot water, the heating / hot water conversion valve 9 is configured to shut off the heating water recovery pipe 13 to be used for both hot water and heating. However, in such a conventional apparatus, the heating water of the heat exchanger 4 is not required for heating as in the summer, and the heating / hot water conversion valve 9 blocks the heating water recovery pipe 13 even when the water heater is used. Since the circulates directly through the heating / hot water conversion valve 9 and the circulation pump 10, the thermal efficiency is lowered, the consumption of power according to the rotation of the circulation pump 10 increases, and the structure of the heat exchanger 4 There was a flaw that the cost of the product was high due to the complexity.

본 고안은 이러한 점을 감안하여 안출한 것으로, 열교환기에 설치된 급수관과 온수공급관에 난방수회수관과 난방수공급관을 각각 병렬로 연결하되, 급수관과 온수공급관에는 솔레노이드 밸브와 리이드스위치를 각각 부착하고, 난방수공급관에는 온도조절기 감열관을 부착하며, 또한 난방수회수관에는 압력스위치, 역류방지용 밸브 및 순환펌드를 설치하여 근본적 기능은 1관 1수식이면서도 리이드스위치의 감지 및 별도의 선택스위치의 조직에 따라 솔레노이드밸브 및 순환펌프가 동작하여 온수전용 및 난방ㆍ온수 겸용으로 사용할 수 있는 것으로, 첨부한 도면에 의하여 상세히 설명하면 다음과 같다.The present invention has been devised in view of this point, and the heating water recovery pipe and the heating water supply pipe are respectively connected in parallel to the water supply pipe and the hot water supply pipe installed in the heat exchanger, and the solenoid valve and the lead switch are attached to the water supply pipe and the hot water supply pipe, respectively.

또한, 제4도에 도시한 바와 같이 상기 리이드스위치(17)는 릴레이스위치(21)에 접속하고, 그 릴레이스위치(21)의 단자(NC)는 선택스위치(18a)의 온수ㆍ난방 겸용 단자(a1)와 온수단자(a2)에 공통접속하여 그 선택스위치(18a)를 솔레노이드밸브(16)에 연결하고, 릴레이스위치(21)의 단자(NO)는 선택스위치(18b)의 온수ㆍ난방 겸용 단자(b1)에 접속하여 그 선택스위치(18b)를 온도조절기(19), 순환펌프(10) 및 압력스위치(14)이 직렬 접속한다.As shown in FIG. 4, the lead switch 17 is connected to the relay switch 21, and the terminal NC of the relay switch 21 is a hot water / heating / combination terminal of the selection switch 18a. a 1 ) and the hot water terminal a 2 are connected in common, and the selector switch 18a is connected to the solenoid valve 16, and the terminal NO of the relay switch 21 is connected to the hot water and heating of the selector switch 18b. the common terminal (1 b) connected to the selecting switch (18b), a thermostat 19, the circulation pump 10 and the pressure switch 14 is connected in series to this.

여기서 리이드 스위치(17)는 온수공급관(3)의 수위를 감지하는 스위치로서 온수공급관(3)에 부착된 온수공급용 콕크(도시하지 않았음)를 열어 수위가 감소하면 오프되고, 온수공급용 콕크를 잠가 수위가 상승하면 이를 감지하여 온되는 스위치이고, 릴레이 스위치(21)는 그의 코일(11)에 전류가 흘러 여자될때 단자(NO)에 접속되고, 여자되지 않을때는 단자(NC)에 접속되는 스위치이며, 선택스위치(18a), (18b)는 서로 연동되는 3단 스위치이다.Here, the lead switch 17 is a switch for detecting the water level of the hot water supply pipe (3) is turned off when the water level decreases by opening the hot water supply cock (not shown) attached to the hot water supply pipe (3), the cock for hot water supply When the water level rises, the switch is sensed and switched on. The relay switch 21 is connected to the terminal NO when the current flows through the coil 11 and is connected to the terminal NC when not excited.

이와 갈이 구성된 본 고안의 작용ㆍ효과를 상세히 설명하면 다음과 같다.If described in detail the operation and effect of the present invention is composed of the following.

먼저, 난방은 하지 않으면서 온수만을 사용하는 경우에는, 교류전원이 인가된 상태에서 선택스위치(18)를 온수위치에 두면, 선택스위치(18a), (18b)는 온수단자(a2), (b2)에 각각 접속되므로 난방수회수관(13)에 설치된 순환펌프(10)에 전원이 차단되어 순환펌프(10)는 동작되지 않고, 이에 따라 난방수는 순환되지 않게 된다.First, when only hot water is used without heating, when the selector switch 18 is placed in the hot water position while AC power is applied, the selector switches 18a and 18b are connected to the hot water terminals a 2 and ( b 2 ), so that power is cut off from the circulation pump 10 installed in the heating water recovery pipe 13 so that the circulation pump 10 is not operated, and thus the heating water is not circulated.

이때, 온수공급관(3)에 물이 없는 상태이면 리이드 스위치(17)는 오프상태가 되어 릴레이 스위치(21)의 코일(L1)에 전류가 흐르지 않으므로 릴레이스위치(21)는 여자되지 않는다. 따라서 릴레이스위치(21)는 그의 단자(NC)에 접속되어 선택스위치(18a)의 온수단자(a2)를 통하여 솔레노이드 밸브(16)에 전원을 인가하므로 솔레노이드밸브(16)는 동작되어 개방되고, 이이 따라 열교환기(4)에 급수가 시작되고 온수로 가열되고, 이 온수는 온수공급관(3)에 공급된다.At this time, if there is no water in the hot water supply pipe 3, the lead switch 17 is turned off, so no current flows in the coil L 1 of the relay switch 21, so that the relay switch 21 is not excited. Accordingly, since the relay switch 21 is connected to its terminal NC to apply power to the solenoid valve 16 through the hot water terminal a 2 of the selector switch 18a, the solenoid valve 16 is operated and opened. Accordingly, water supply to the heat exchanger 4 starts and is heated with hot water, which is supplied to the hot water supply pipe 3.

이때, 온수공급용 콕크가 열린 상태이면 상기의 설명에서와 같이 리이드 스위치(17)는 계속 오프상태를 유지하여 솔레노이드밸브(16)를 개방시키므로 급수는 계속되어 온수공급관(3)에 온수가 계속 공급되게 된다.At this time, if the hot water supply cock is open, the lead switch 17 continues to be in the off state to open the solenoid valve 16 as described above, so that water supply is continued and hot water is continuously supplied to the hot water supply pipe 3. Will be.

그러나, 온수공급용 콕크가 잠긴 상태이면 온수공급관(3)의 수위가 상승하여 리이드 스위치(17)를 접속시키므로 릴레이스위치(21)의 코일(L1)에 전류가 흘러 릴레이 스위치(21)는 여자되고, 이에 따라 릴레이스위치(21)는 그의 단자(NO)에 접속되어 솔레노이드밸브(16)에 전원을 차단하므로 급수는 자동으로 중단된다.However, when the hot water supply cock is locked, the water level in the hot water supply pipe 3 rises to connect the lead switch 17, so that a current flows in the coil L 1 of the relay switch 21 so that the relay switch 21 is excited. As a result, the relay switch 21 is connected to the terminal NO thereof to cut off the power supply to the solenoid valve 16, so that the water supply is automatically stopped.

그리고, 난방ㆍ온수 겸용으로 사용하기 위해 선택스위치(18)를 온수ㆍ난방 겸용위치에 두면, 선택스위치(18a), (18b)는 온수ㆍ난방 겸용 단자(a1), (b1)에 접속되고, 또한, 상기의 설명에서와 같이 온수공급용 콕그가 잠긴 상태에서는 리이드스위치(17)가 접속되어 릴레이스위치(21)는 그의 단자(NO)이 접속되므로 솔레노이드 밸브(16)에 전원이 차단되어 급수는 중단된다.Then, when the selector switch 18 is placed in the hot / heating combined position to be used for both heating and hot water, the selector switches 18a and 18b are connected to the hot / heating dual-use terminals a 1 and b 1 . In addition, in the state where the hot water supply cock is locked as described above, the lead switch 17 is connected and the relay switch 21 is connected to the terminal NO thereof, so that the power supply is disconnected from the solenoid valve 16. Watering is stopped.

그러나, 순환펌프(10)에는 온도조절기(19)를 통하여 전원이 인가되므로 순환펌프(10)는 동작되고, 이에 따라 난방수회수관(13)의 난방수는 역루방지용 밸브(15)와 압력스위치(14)를 통하여 열교환기(4)이 순환되므로 정상적인 난방작용을 수행하게 된다.However, since the circulation pump 10 is supplied with power through the temperature controller 19, the circulation pump 10 is operated, whereby the heating water of the heating water recovery pipe 13 is a check valve 15 and a pressure switch to prevent backflow. Since the heat exchanger 4 is circulated through the 14, normal heating is performed.

이때에 만약 난방수공급관(12) 또는 난방수회수관(13)내에 막힘과 같은 이상이 발생하여 일정이상의 압력이 가해지면 압력스위치(14)는 저절로 오프되어 순환펌프(10)의 동작을 중지시키므로 안전사고를 미연에 예방할 수 있게 되고, 또한 난방수공급관(12)내의 난방수의 온도가 온도조절기(19)의 실정온도 이상이 되면, 이를 온도조절기 감열관(11)에서 감지하여 온도조절기(19)를 오프시키므로 순환펌프(10)는 동작을 중지하여 난방수의 순환을 중지시키게 된다.At this time, if an abnormality such as a blockage occurs in the heating water supply pipe 12 or the heating water recovery pipe 13 and a predetermined pressure is applied, the pressure switch 14 turns off by itself to stop the operation of the circulation pump 10. Safety accidents can be prevented in advance, and when the temperature of the heating water in the heating water supply pipe 12 becomes higher than the actual temperature of the temperature controller 19, the temperature controller heat sensing pipe 11 detects this and adjusts the temperature controller 19. By turning off), the circulation pump 10 stops the circulation of the heating water by stopping the operation.

이와 같이 난방수공급관(12) 및 난방수회수관(13)을 통하여 순환되는 도중에 온수를 사용하고자 하여 온수용 콕크를 열게 되면, 상기의 설명에서와 같이 리이드 스위치(17)가 오프되어 릴레이스위치(21)는 그의 단자(NO)에 접속되므로 순환펌프(10)에 인가되는 전원이 차단되어 순환펌프(10)는 동작을 중지하나, 솔레노이드 밸브(16)에는 전원이 인가되어 그를 개방시키므로 열교환기(4)에 급수가 되어 온수공급관(3)에 온수가 계속 공급된다.When the hot water cock is opened to use hot water while being circulated through the heating water supply pipe 12 and the heating water collection pipe 13 as described above, the lead switch 17 is turned off as described above and the relay switch ( Since 21 is connected to the terminal NO thereof, the power applied to the circulation pump 10 is cut off and the circulation pump 10 stops operation, but the power is applied to the solenoid valve 16 to open the heat exchanger ( Water is supplied to 4) and hot water is continuously supplied to the hot water supply pipe (3).

이러한 도중에 온수사용이 끝나 온수용 콕크를 잠그게 되면 상기의 설명에서와 같이 리이드 스위치(17)가 접속되어 릴레이스위치(21)를 그의 단자(NO)에 접속시키므로 솔레노이드 밸브(16)는 동작을 중지하여 급수가 중단되고, 순환펌프(10)는 동작하여 난방수를 순환시키게 된다.In this way, when the hot water is used and the cock is closed, the solenoid valve 16 stops operation because the lead switch 17 is connected and the relay switch 21 is connected to its terminal NO as described above. The water supply is stopped and the circulation pump 10 operates to circulate the heating water.

그리고 선택스위치(18)를 정지위치에 두면, 선택스위치(18a) (18b)는 오프된 상태를 유지하여 솔레노이드 밸브(16)와 순환펌프(10)는 모두 동작하지 않게 된다.When the selector switch 18 is placed at the stop position, the selector switches 18a and 18b remain off, so that both the solenoid valve 16 and the circulation pump 10 do not operate.

이와 같이 동작되는 본 고안은 근본적 기능은 1관 1수식이면서도, 난방용 순환수 및 온수공급이 필요한 시점에 간단한 스위치 조작만으로 가능하므로 사용하기 대단히 간편하고, 그의 구조가 간단하여 원가 및 실비비가 대단히 절감되며, 또한 온수사용시에만 급수가 자동으로 되고, 난방수 순환로에 막힘과 같은 이상이 발생할 경우나 설정된 온도 이상이 되었을 경우에는 난방수 순환펌프가 자동으로 동작을 중지하게 되므로 필요없는 열소비가 없고, 제품의 신뢰성이 향상되는 효과가 있게 된다.This design, which operates in this way, is a one-pipe one-type formula, but it is very simple to use because it is possible to operate by simple switch operation when heating circulation water and hot water supply are needed, and its structure is simple, and the cost and actual cost are greatly reduced. In addition, water is automatically supplied only when hot water is used, and when there is an abnormality such as clogging in the heating water circulation path or when the temperature is over the set temperature, the heating water circulation pump automatically stops operation, so there is no unnecessary heat consumption. The reliability of the effect is improved.
