Abstract

본 발명은 가스보일러의 난방 및 온수겸용모드에서 온수사용시 일시적인 온수중단을 행한 후 재차 온수를 사용할 경우 곧바로 삼방밸브가 난방위치로 전환되지 않고 온수사용이 중단되어도 온수온도가 일정온도로 유지되는 상태에서 일정시간 동안 삼방 밸브를 온수위치에 있게 한후 일정의 신간이 경과하면 난방위치로 전환되게한 가스보일러의 온수연장시스템에 관한 것인 바, 이는 사용자가 온수사용을 선택하면, 유수감지기(2a)가 온상태인지를 판별하여 온상태이면 온도조절센서와 가스밸브(3a)를 온시키고, 삼방밸브(1a)의 볼이 "b"위치에 놓이게 하여 온수라인(2)이 온되도록 하며, 배기팬과 순환펌프를 온시켜 온수를 사용을 가능하게하며, 이후 사용자가 일시적으로 온수사용을 중단하면, 유수감지기(2a)가 오프상태가 되며, 이후 온수온도가 80℃이상인지 여부를 판단하여 온수온도가 80℃이상이면 일정시간 즉, 약 5분동안 삼방밸브(1a)를 온수위치에 있게 한후이 시간이 경과되면 삼방밸브(1a)의 볼이 "b"위치에 놓이게 하여 난방으로 전환되게 하고, 상기 온수온도가 80℃이하일 경우에는 가스밸브(3a)를 온시켜 온수온도가 80℃에 이르기까지 가열한 이후에 다시 온수온도가 80℃에 이르렀는지를 판별하여 이상이 되면 상기와 같이 약 5분동안 온수상태를 유지하다가 난방으로 가동되게 함으로써 일정한 상기 시간( T)이내에서 재차 온수사용을 선택하게 되면, 즉시에 온수가 출탕되는 효과를 얻을 수 있도록 한 것이다.According to the present invention, when the hot water is temporarily turned off when the hot water is used in the heating and hot water combined mode of the gas boiler, the hot water is maintained at a constant temperature even when the three-way valve is not switched to the heating position and the hot water is stopped. It is related to the gas boiler's hot water extension system that causes the three-way valve to be in the hot water position for a certain time and then switches to the heating position when a certain time elapses. When the user selects the use of hot water, the water flow detector 2a If it is in the on state, the temperature control sensor and the gas valve (3a) is turned on, the ball of the three-way valve (1a) is placed in the "b" position so that the hot water line (2) is turned on, and the exhaust fan and The hot water can be used by turning on the circulating pump, and when the user temporarily stops using the hot water, the water flow sensor 2a is turned off, and the hot water temperature is 80 ° C. If it is determined whether or not the hot water temperature is higher than 80 ℃, the three-way valve (1a) in the hot water position for a certain time, that is, about 5 minutes, after this time elapses, the ball of the three-way valve (1a) in the "b" position When the hot water temperature is 80 ° C. or lower, turn on the gas valve 3a to heat the hot water temperature to 80 ° C., and then determine whether the hot water temperature reaches 80 ° C. again. In this case, the hot water is maintained for about 5 minutes as described above, and when the hot water is used again within the predetermined time T, the hot water is immediately tapped.

Claims

If the user selects the use of hot water during heating operation, the water flow sensor is turned on, the temperature control sensor and the gas valve are turned on, and the three-way valve is switched to the hot water position so that the hot water line is turned on. When the water is stopped, the water flow sensor is turned off, and when the water temperature is lower than the constant temperature (Δ ℃), the gas valve is turned on to reach the hot water temperature (Δ ℃) and reheated to maintain the constant temperature (ΔT). After the elapse of) the three-way valve is switched to heating to turn on the heating line, at the same time hot water line system, characterized in that the hot water line is off.

The hot water extension system according to claim 1, wherein the constant hot water temperature (Δ ° C.) determined at the time of stopping the use of the hot water is 80 ° C. or more.

The hot water extension system of claim 1, wherein a predetermined time (ΔT) set at the time of stopping the use of the hot water is set to about 5 minutes.
