가정용 가스 보일러의 펌프 구동 지연장치Pump driven delay device for domestic gas boiler

제1도는 본 고안 장치의 회로도.1 is a circuit diagram of the device of the present invention.

본 고안은 가정용 가스 보일러의 펌프 구동지연 장치에 관한 것으로서 특히 가스 보일러의 순환수의 온도를 온도 감지기로 감지하여 순환 펌프의 구동을 지연시키기 위한 펌프구동 지연장치에 관한 것이다.The present invention relates to a pump driving delay device for a domestic gas boiler, and more particularly to a pump driving delay device for delaying the operation of the circulation pump by detecting the temperature of the circulating water of the gas boiler with a temperature sensor.

종래의 가정용 가스 보일러에서는 솔레노이드를 가스 밸브에 설치하여 가스 보일러를 끄기위해서 또는 난방온도 및 온수온도를 제어하기 위하여 솔레노이드의 공급전원을 차단시킴과 동시에 순환펌프의 전원을 차단하는 방식을 채용하고 있으나 가스밸브와 모터를 동시에 오프시키면 순환수의 순환이 정지되어 가스밸브가 설치된 가열부의 잠열에 의하여 순환수가 과열되어 가스 보일러 장치에 열충격이 발생되므로 장치의 수명이 단축되는 단점이 있고 또다른 종래의 방식으로는 가스밸브의 솔레노이드 공급전원이 차단되면 무조건 소정시간동안 순환펌프를 구동켜 순환수를 순환시키도록한 것이 있으나 가스 밸브가 설치된 가열부의 잠열이 적은 경우에도 순환펌프가 구동되므로 필요없는 펌프구동에 따른 전력의 낭비가 발생될뿐 아니라 오히려 열교환기내의 열을 외부로 방출시키는 작용을 하게되어 에너지의 낭비가 크게되는 단점이 있다.In the conventional domestic gas boiler, a solenoid is installed in the gas valve to turn off the gas boiler or to control the heating temperature and hot water temperature. When the valve and the motor are turned off at the same time, the circulation of the circulating water is stopped and the circulating water is overheated by the latent heat of the heating unit where the gas valve is installed. When the solenoid supply power of the gas valve is cut off, the circulating water is circulated by circulating the pump for a predetermined time, but the circulating pump is operated even if the latent heat of the heating part where the gas valve is installed is low. Not only waste of power, but rather There is a disadvantage in that the waste of energy is large because it serves to release the heat in the heat exchanger to the outside.

본 고안은 이러한 단점을 해결하기 위하여 순환수의 온도를 감지할 수 있도록 온도 감지기를 순환수로내에 설치하고 가스 밸브의 구동 솔레노이드 전원의 차단과는 무관하게 온도 감지기로서 순환펌프의 구동용 모터의 전력을 제어하므로서 잠일에 의한 열 충격을 방지하여 장치의 수명을 연장하고 열효율을 높힘과 동시에 필요없는 순환펌프의 구동을 방지하여 순환펌프 구동 전력을 절감할 수 있는 가정용 가스 보일러의 펌프 구동 지연장치를 제공하는 것을 목적으로하며, 이하 첨부된 도면을 참조하며서 본 고안의 구성 및 효과를 설명하면 다음과 같다.In order to solve this drawback, the present invention installs a temperature sensor in the circulating water path to detect the temperature of the circulating water, and the electric power of the motor for driving the circulating pump as a temperature sensor is irrelevant regardless of the shutoff of the solenoid power supply of the gas valve. Providing a pump driving delay device for a domestic gas boiler that can reduce the driving power of the circulation pump by preventing the thermal shock caused by the sleep, thereby extending the life of the device, increasing the thermal efficiency and preventing unnecessary circulation pump driving. For the purpose, the configuration and effects of the present invention will be described below with reference to the accompanying drawings.

우선 제1도를 참조하면 본 고안 장치의 구성은 상용 AC전원단자(a, b)에 제1계전기(1)이 이자권선(L1)과 유수감지스위치(S1)를 연결하고, 상용 전원단자(a)에 연결된 삼방전자밸브(2)의 제어단자(C1, C2)에 제1계전기(1)의 제1접점(IC)중 상시개방접점(L10)과 상시폐쇄접점(Lic)을 각각 연결하되 제1접점(IC)중 가동접점(L1M)구동 난방 및 온수 전환용 스위치(SW1)일단과 실내온도 조절기 내장스위치(SW3)일단의 접속점에 연결함과 동시에 제1계전기(1)의 제2접점(2C)중 상시 개방접점(L20)에 연결하며, 스위치(SW2)의 타단은 상용전원단자(b)와 제2접점(2c)중 가동자접점(L2M)에 연결하고, 제2접점(2c)중 상시 폐쇄접점(L2c)은 온도 감지스위치(SW4)와 제3계전기(3)의 여자권선(L3)을 통하여 상용 AC전원단자(a)에 연결함과 동시에 제3계전기(3)의 상시 개방접점(Lo3)에 연결하며, 순환펌프의 모터(4)의 표시램프(5)의 병렬접속의 일단은 상용 AC 전원단자(a)에 연결하되 타단은 제3계전기(3)의 가동자접점(LM3)에 연결하며, 제3계전기의 상시폐쇄접점(LC3)은 실내온도 조절기 내장 스위치(SW3)타단과 가스밸브용 솔레노이드(6)의 일단에 연결하되 제1계전기(1)의 제3접점(3c)중 가동접점(L3M)과 상시 개방접점(L30)을 실내온도 조절기 내장스위치(SW3)에 병렬 접속하여된 것으로서 여기에서, 미설명 부호 7:공지의 동파 방지 계전기의 접점 21:온수측 밸브 전환스위치 22:난방측 밸브 전환스위치이다. 이러한 본 고안 구성의 작용효과는 먼저 난방측 밸브 전환스위치(22)를 눌려서 삼방전자 밸브(2)가 난방측으로 순환수를 공급하는 경우에는 상용 AC 전원단자(a,b)에 인가된 전원은 수동 난방 및 온수 전환용 스위(SW2)를 통하고 실내온도 조절기 내장 스위치(SW3)를 통하여 가스밸브용 솔레노이드(6)가 인가되므로 공지의 가열부내의 가스밸브가 열려 가스가 유출되어 점화된다. 점화된 가스불꽃은 가열부내의 순환수를 가열하게된다. 동시에 제3계전기(3)의 상시 폐쇄접점(LC3)과 가동자 접점(LM3)을 통하여 순환펌프의 모터(4)와 표시램프(5)에 전원이 인가되어 순환펌프(도시되지 않음)는 순환수를 순환시키게되고 표시램프(5)는 점등되어 현재 순환펌프의 모터(4)가 작동중임을 표시하게 된다. 순환수가 가스밸브에 의하여 계속 가열되어 실내 온도 조절기에서 셀링된 온도 이상으로 상승하면 실내온도 조절기 내장스위치(SW3)가 오프됨과 동시에 온도감지 스위치(SW4)가 온되어서 제3계전기(3)의 여자권선(L3)에 전원이 인가된다.First, referring to FIG. 1, the device of the present invention has a commercial AC power terminal (a, b) connected to the first relay (1) by the interest winding (L 1 ) and the water flow detection switch (S 1 ), and commercial power The normally open contact (L 10 ) and the normally closed contact (Lic) among the first contacts (IC) of the first relay (1) to the control terminals (C 1 , C 2 ) of the three-way solenoid valve (2) connected to the terminal (a). ) to, but each connection at the same time as the first contact (IC) of the movable contact (L 1 M) driving switch for heating and hot water switch (SW 1) once and climate control internal switch (SW 3) connected to the connection point of one end the One of the second contacts 2C of the relay 1 is connected to the normally open contact L 20 , and the other end of the switch SW 2 is connected to the movable contact among the commercial power supply terminals b and the second contact 2c. L2M) a normally closed contact (L 2 c) of the connection on, and the second contact (2c) are temperature detection switch (commercial AC power supply terminal through a winding (L 3) of the SW 4) and the third relay (3) ( connected to a), and at the same time to the normally open contact (3 Lo) of the third relay (3) Results, and one end of the parallel connection of the display lamp 5 of the motor 4 of the circulating pump is connected to the movable contact (LM 3) of a third relay (3) the other end, but connected to a commercial AC power supply terminal (a) The normally closed contact point LC 3 of the third relay is connected to the other end of the switch SW 3 having an internal temperature controller and one end of the solenoid 6 for the gas valve, but the third contact point 3c of the first relay 1 is connected. The movable contact (L3M) and the normally open contact (L30) are connected in parallel to the switch (SW 3 ) with a built-in temperature controller. Here, reference numeral 7: Contact 21 of the freeze protection relay of a known type: Valve switching on the hot water side Switch 22: Heating valve changeover switch. The effect of the present invention is that the power applied to the commercial AC power supply terminals (a, b) when the three-way valve 2 supplies the circulating water to the heating side by pressing the heating valve switch switch 22 first Since the gas valve solenoid 6 is applied through a switch SW 2 for heating and hot water switching and a switch SW 3 having a built-in temperature controller, a gas valve in a known heating unit is opened to ignite the gas. The ignited gas flame heats the circulating water in the heating unit. At the same time, power is applied to the motor 4 and the display lamp 5 of the circulation pump through the normally closed contact LC3 and the movable contact LM3 of the third relay 3 so that the circulation pump (not shown) is circulated. The number is circulated and the indicator lamp 5 is turned on to indicate that the motor 4 of the circulation pump is currently operating. When the circulating water continues to be heated by the gas valve and rises above the temperature that is selected by the indoor temperature controller, the internal temperature controller internal switch SW 3 is turned off and the temperature sensing switch SW 4 is turned on to turn on the third relay 3. Power is applied to the excitation winding L 3 .

이에 따라서 제3계전기(3)의 가동자 접점(LM3)은 상시 개방접점(LO3)에 접속되고 이때에는 제1계전기(1)의 제2접점(2c)의 가동자 접점(L2M)과 상시 폐쇄접점(L2c)를 통하여 전원이 공급되므로 순환펌프의 모터(4)에는 전원이 인가되어 순환수가 계속 순환하게되나 가스밸브용 솔레노이드(6)의 전원 인가가 차단되어 순환수의 가열은 중지된다.Accordingly, the mover contact LM 3 of the third relay 3 is connected to the normally open contact LO 3 , and at this time, the mover contact L2M of the second contact 2c of the first relay 1 is connected. Since power is supplied through the normally closed contact point L2c, power is applied to the motor 4 of the circulating pump to continuously circulate the circulating water, but the application of power to the gas valve solenoid 6 is cut off and the heating of the circulating water is stopped. .

그러므로 순환수의 과열이 방지되어 가정용 보일러 장치에 열충격이 방지되는 것이다.Therefore, overheating of the circulating water is prevented and thermal shock is prevented in the domestic boiler apparatus.

이후 순환수 온도가 소정온도 이하로 되면 온도 감지스위치(SW4)가 오프되어 제3계전기(3)의 여자권선(L3)의 전원을 차단하므로 제3계전기(3)의 가동접점(LM3)은 상시폐쇄접점(L3)에 접속되므로 순환펌프이 모터(4)의 전원공급이 차단된다.When the circulating water temperature is lower than the predetermined temperature, the temperature sensing switch SW 4 is turned off to cut off the power of the excitation winding L 3 of the third relay 3, so that the movable contact LM 3 of the third relay 3 is closed. ) Is connected to the normally closed contact (L 3 ), the circulation pump is cut off the power supply of the motor (4).

이에 따라서 순환수의 순환이 정지되어 열교환기내의 열이 순환수의 순환을 따라서 외부로 방출되는 것이 방지된다.Accordingly, the circulation of the circulating water is stopped to prevent the heat in the heat exchanger from being released to the outside along the circulation of the circulating water.

또한 난방이 필요없고 온수가 필요한 경우에는 수동난방 온수 전환스위치(SW2)를 오프하고 스위치(22)를 온하면 삼방밸브(2)가 온수축으로 순환수를 공급하게 된다. 이때 사용자가 온수코크를 열면 물이 흐르게되고 물의 흐름을 유수감지 스위치(S1)가 감지하게 되어 유수감지(S1)가 온되어 제1계전기(1)의 여자권선(L1)에 전원이 인가된다.In addition, when heating is not required and hot water is required, when the manual heating hot water conversion switch SW 2 is turned off and the switch 22 is turned on, the three-way valve 2 supplies circulating water to the hot water shaft. In this case the user and the water flow and the leading detect the water flow switch to open the hot water cock (S 1) is the detected leading sensing (S 1) is turned on, the power to the field winding (L 1) of the first relay (1) Is approved.

따라서 제1계전기(1)의 접점(1C,2C,3C)의 가동자 접점(L1M2, L2M, LCM)은 상기 개방접점(L10, L20, L30)에 접속된다.Accordingly, the first movable contact (L1M2, L2M, LCM) of the contact (1C, 2C, 3C) of the relay (1) is connected to the open contact point (L 10, L 20, L 30).

그러므로 수동 난방온수 전환스위치(SW2)에 병렬 접속된 제2접점(2C)과 실내온도 조절기 내장스위치(SW3)에 병렬접속된 제3접점(3C)을 통하여 전원은 가스밸브의 솔레노이드(6)에 인가되어 점화되어 순환수를 가열하게됨과 동시에 제3계전기(3)의 상시폐쇄접점(LC3)과 가동자 접점(LM3을 통하여 순환펌프의 모터(4)와 표시램프(5)에 전원이 인가되어 순환수가 순환하게된다. 유수 감지스위치(S1)가 온된 상태에서 순환수가 소정온도 이상이되면 온도 감지스위치(SW4)가 온되어 제3계전기(3)의 이자권선(L3)에 전원이 인가되며 제3계전기(3)의 가동자접점(LM3)이 상시 개방접점(Lo3)에 접속되므로 순환펌프의 모터(4)에 전원인가를 차단하게 되어서 필요없이 순환펌프를 작동시키지 않게된다.Therefore, power is supplied to the solenoid of the gas valve through the second contact point 2C connected in parallel to the manual heating / hot water changeover switch SW 2 and the third contact point 3C connected in parallel to the switch SW 3 built in the room temperature controller. ) Is ignited to heat the circulating water and at the same time to the normally closed contact LC 3 of the third relay 3 and the mover contact LM 3 to the motor 4 and the display lamp 5 of the circulation pump. When power is applied, the circulating water circulates When the circulating water reaches a predetermined temperature or more while the water flow detection switch S 1 is turned on, the temperature sensing switch SW 4 is turned on and the interest winding L 3 of the third relay 3 is turned on. The power is supplied to the motor and the movable contact LM 3 of the third relay 3 is connected to the normally open contact Lo 3 so that the power supply to the motor 4 of the circulation pump is cut off to operate the circulation pump without any need. Will not let you.

따라서 필요없이 모터 구동에 의한 전력손실을 방지할 수 있다.Therefore, it is possible to prevent the power loss by driving the motor without need.

이후 사용자가 온수코크를 잠그면 유수 감지 스위치(S1)가 오프되어 제1계전기(1)의 여자권선(L1)에 전원 인가를 차단하므로 제1계전기(1)의 제3접점(1c~3c)의 가동자 접점들이 상시 폐쇄접점으로 절환되어 순환펌프의 모터(4), 표시램프(5) 및 가스밸브의 솔레노이드(6)의 전원 인가가 차단되어 모든 작동이 정지된다.Then, when the user locks the hot water coke, the water flow detection switch S 1 is turned off to cut off the power supply to the excitation winding L 1 of the first relay 1, so that the third contact point 1c to 3c of the first relay 1 is closed. The movable contact of the) is switched to the normally closed contact so that the power supply of the motor 4 of the circulation pump, the display lamp 5 and the solenoid 6 of the gas valve is cut off and all operations are stopped.

이상에서 설명된 바와 같이 본 고안장치에 의하면 난방운전시 열충격에 의한 장치의 수명 단축을 방지할 수 있을뿐 아니라 순환수의 과열을 방지할 수 있고 온수 운전시에는 필요없는 순환펌프의 모터 구동을 방지하여 소비전력을 절감할 수 있는 것이다.As described above, the device according to the present invention can not only shorten the lifespan of the device due to thermal shock during heating operation, but also prevent overheating of the circulating water, and prevent the motor driving of the circulating pump, which is unnecessary during the hot water operation. To reduce power consumption.
