Embodiment 1
[0025] Depend on Figure 1-Figure 2 As shown, this embodiment provides an intelligently controlled dual heat source gas heating water heater, including a controller 1, a heating system 2, a gas heating system 4 and an electric heating system 3;
[0026] The heating system 2 includes a heating return pipe 21 and a heating outlet pipe 22 connected to the gas heating system 4; the heating return pipe 21 is used to input heating water, heated by a gas heating device, and the heated circulating water is passed through the heating The outlet pipe 22 is transported to the heating circulation pipeline to heat the room; the heating return pipe 21 is sequentially provided with a heating return ball valve 23, a pressure gauge 24 and a circulation pump 25 from the water inlet; the heating return ball valve 23 is used to To adjust the flow of the return water pipeline, the pressure gauge 24 is used to detect the pressure value on the heating circulation pipeline, and the circulation pump 2...
Embodiment 2
[0031] This embodiment is developed on the basis of the above embodiments. Specifically, this embodiment discloses an intelligently controlled dual heat source gas heating water heater. The heating system 2 also includes an expansion tank 26, and the expansion tank 26 is connected to the heating return pipe 21 through a safety valve 27; the expansion water tank 26 is arranged between the heating return water ball valve 23 and the circulation pump 25; the expansion water tank 26 is used when the water in the heating circulation pipe is insufficient , supply water to the heating circulation pipeline through the expansion tank 26 .
[0032] In some preferred implementations, the hot water outlet pipe 34 is provided with a fourth temperature controller 35 for detecting the temperature of the hot water outlet pipe 34 to ensure comfortable water at the user end.
[0033] In some preferred embodiments, a first overheating protector 29 is also provided on the heating outlet pipe 22; a...
Embodiment 3
[0040] This embodiment is developed on the basis of the above embodiments. Specifically, this embodiment provides a working principle of an intelligently controlled dual heat source gas heating water heater, as follows:
[0041] (1) Use hot water when the heating system 2 is not in use: cold water enters from the water inlet of the cold water pipe 42 and passes through the one-way safety valve 44 and the flow sensor 45. When the flow sensor 45 detects that the water flow reaches the set value, it sends a signal to Controller 1, the controller 1 controls the gas valve to open, the heating device heats the cold water, the heated hot water flows to the hot water pipe 43 and reaches the water storage tank 31 through the third temperature controller 47, at this time, the electric heating control switch 36 is turned off state, hot water flows to the user end through the water storage tank 31 through the hot water outlet pipe 34 to ensure that the user uses water.
[0042] (2) Use ho...
