일반적으로 가스 온수기는 직수를 단시간 내에 소정의 온도로 가열하여 사용자가 편리하게 온수를 사용할 수 있도록 구성된 장치이다.In general, a gas water heater is a device configured to enable the user to conveniently use hot water by heating the water directly to a predetermined temperature within a short time.
종래의 가스 온수기는, 직수가 유입되는 직수관, 상기 직수관 상에 설치되어 직수의 유량을 측정하는 유량센서, 상기 유량센서를 통과한 직수를 버너의 연소에 의해 열교환이 이루어지는 열교환기, 상기 열교환기에서 가열된 온수가 흐르는 온수관, 상기 온수관상에 설치되어 배출되는 온수의 유량을 조절하는 유량조절밸브, 상기 직수관과 온수관 사이를 연결하는 바이패스관, 및 상기 바이패스관 상에 설치되어 바이패스관을 통해 이송되는 직수의 유량을 조절하는 믹싱밸브가 구비되어 있다.Conventional gas water heaters, a heat pipe for direct water flow, a flow sensor installed on the water pipe to measure the flow of the direct water, the heat exchanger heat exchange is performed by the burner combustion of the direct water passing through the flow sensor, the heat exchange A hot water pipe through which hot water heated in the air flows, a flow control valve for controlling the flow rate of hot water discharged and installed on the hot water pipe, a bypass pipe connecting the direct water pipe and the hot water pipe, and the bypass pipe The mixing valve is provided to adjust the flow rate of the direct water is passed through the bypass pipe.
사용자가 온수 사용을 요청하면 상기 직수관을 통해 흐르는 직수의 일부는 상기 열교환기에서 온수가 되어 상기 온수관을 통해 온수사용처로 공급되고, 상기 직수의 나머지는 상기 믹싱밸브 및 바이패스관을 통해 상기 온수관에 합류되어 상기 온수사용처로 공급되는 온수의 온도를 조절할 수 있도록 되어 있다.When the user requests the use of hot water, a part of the direct water flowing through the direct water pipe becomes hot water in the heat exchanger and is supplied to the hot water use place through the hot water pipe, and the rest of the direct water is discharged through the mixing valve and the bypass pipe.
