the water using pipeline at least comprises two pipeline units and is used for connecting water using points; each of the pipe units connects the water outlet and the water inlet to form a hot water circulation loop 100 with the internal pipe;
the water using pipeline at least comprises two pipeline units and is used for connecting water using points; each of the pipe units connects the water outlet and the water inlet to form a hot water circulation loop 100 with the internal pipe; each hot water circulation loop 100 is provided with an electromagnetic valve 101 and a water flow sensing device 102; the water flow sensing device 102 is located at the upstream of the electromagnetic valve 101, and is arranged on a pipeline between a hot water output end of the water consumption point on the hot water circulation loop 100 and the water inlet;
the electromagnetic valves 101 and the water flow sensing devices 102 are both connected to the controller 3, and the controller 3 is configured to receive water flow signals from the water flow sensing devices 102 and control opening and closing of the electromagnetic valves 101 on the hot water circulation loop 100 corresponding to the water flow sensing devices 102.

The water flow signal of each water flow sensing device 102 fed back to the controller 3 may include water flow information.
For example, when the water flow signal fed back to the controller 3 is water flow, the controller 3 can determine whether the current operation mode is preheating or heating according to the change speed of the water flow, so as to control the on/off of the solenoid valve 101 on the hot water circulation loop 100 corresponding to each water flow sensing device 102.

In the present embodiment, the different water flow directions refer to the outlet directions of the hot water at the hot water outlet of the water heater 1.
For example, when the pipes in which hot water flows into a plurality of water consumption points are located on the same side of the water heater 1 at the hot water outlet of the water heater 1, the water consumption points with the same water flow direction can be considered. As shown in fig. 2, the first water point and the third water point are identified as water consumption points with the same water flow direction, the second water point and the first water point, and the second water point and the third water point are identified as water consumption points with different water flow directions.

In an example, the water using pipeline includes a first pipeline unit and a second pipeline unit, the first pipeline unit connects the water outlet and the water inlet to form a first hot water circulation loop, the second pipeline unit connects the water outlet and the water inlet to form a second hot water circulation loop, and a water outlet direction of the first hot water circulation loop is different from a water outlet direction of the second hot water circulation loop.
In practical implementation, the difference of the water flow signal fed back to the controller 3 when water flows through can be realized by the difference of the structure adopted by the water flow sensing device 102 of different hot water circulation loops 100.
Referring to fig. 1, 2 and 3, for example, the water flow sensing device 102 of one hot water circulation loop 100 employs the water flow sensor 5 or the water flow switch 4, and the water flow sensing device 102 of another hot water circulation loop 100 employs the water flow sensor 5 and the water flow switch 4.

After the preheating operation mode exits, the controller 3 sends a command to the first solenoid valve 6 to close it.
When the first water point or the third water point has a pressurizing requirement, namely the water flow sensor 5 detects that water flows through, the water flow time reaches the preset time and the water flow is larger than the preset flow, a signal with the pressurizing requirement is fed back to the controller 3, the controller 3 sends a starting instruction to the water pump 2, the water pump 2 is started to work, a large amount of water flows into the first water point or the third water point, and the pressurizing function of the first water point or the third water point is realized.
In the pressurization process, the first electromagnetic valve 6 is in a closed state, the water channeling phenomenon can be prevented, the pressurization effect is guaranteed, and after the pressurization requirement is finished, the controller 3 sends an instruction to the water pump 2 again to close the water pump.
In the whole working process of preheating and pressurizing the first water point or the third water point, the second water point in the other water flow direction is not involved, and unnecessary energy consumption is reduced.
When the second water point has a preheating requirement, water flows pass through the water flow sensor 5 and the water flow switch 4, and simultaneously, a water flow signal is fed back to the controller 3, the controller 3 sends an instruction to the second electromagnetic valve 7 and the water pump 2 according to the fed back signal, so that the second electromagnetic valve 7 is opened, and the water pump 2 is started to work, so that the second water point can normally use a preheating function. After the operating mode exits, the controller 3 sends a command to the second solenoid valve 7 to close it.
When the second water point has a pressurization demand, the water flow sensor 5 and the water flow switch 4 have water flow to pass through, and simultaneously feed back a water flow signal to the controller 3, the controller 3 sends an instruction to the water pump 2 according to the fed back signal, and the water pump 2 starts to work, so that the second water point can normally use the pressurization function.
At this time, the second electromagnetic valve 7 is in a closed state, so that the water channeling phenomenon is prevented, and the pressurization effect is ensured; after the water demand is over, the controller 3 sends a command to the water pump 2 to turn it off.
In the whole working process of realizing the preheating and pressurizing functions of the second water flow point, the first water flow point or the third water flow point in the other water flow direction is not involved, and unnecessary energy consumption is reduced.
In this embodiment, at least two water using units are provided to form at least two hot water circulation loops 100, each water using point can be located in different hot water circulation loops 100, and the controller 3 controls the on/off of the electromagnetic valve 101 on each circulation loop 100 according to the water flow signal of each water flow sensing device 102, so that even a water using point with low frequency can be preheated by the hot water circulation loop 100 where the water using point is located, thereby avoiding the problems of complicated laying and large heat dissipation caused by the fact that each water using point is located in the same preheating circulation loop; meanwhile, the controller 3 controls the opening and closing of the electromagnetic valves 101 on the hot water circulation loops 100 according to the water flow signals of the water flow sensing devices 102, so that the control processes of preheating the water consumption points in different water flow directions are not influenced mutually, and the problems that only the water consumption points with higher frequency in the traditional technology are preheated/insulated, and the water consumption points of the hot water circulation loops 100 in other water flow directions cannot be preheated/insulated are solved.
