A fuel-electric complementary hot water system 1 according to an embodiment of the present invention is described below with reference to the drawings.
In some embodiments of the present invention, as shown in fig. 1-8, a gas-electric complementary hot water system 1 according to an embodiment of the present invention includes a gas water heater 100, a plurality of electric water heaters 200, a pipeline switching device 300, an outlet water temperature and flow sensor 900, a controller and an alarm device.
As shown in fig. 2 and 5, the heating pipe 230 is a spiral heating pipe, and the heating pipe 230 is located at the upper portion of the electric water heater 200. The up-down direction is based on the up-down direction of the electric water heater 200 during normal use.
Optionally, the predetermined value is 2 ℃. Thus, the hot water endurance of the heating pipe 230 can be improved, and the water temperature overtemperature caused by the starting of the heating pipe 230 can be avoided.
In some embodiments of the present invention, as shown in fig. 2-4, the line switching device 300 includes a first connector 410, a second connector 420, and a control valve 430. The control valve 430 may be a mechanical valve or an electric valve.
The first and second water inlets 310 and 320 are formed at the first joint 410 and communicate with each other. The first water outlet 330 is formed on the second joint 420. The control valve 430 is switchably connected between the first joint 410 and the second joint 420 between the first state and the second state, and the second water outlet 340 is formed on the control valve 430.
When the control valve 430 is in the first state, the first joint 410 is communicated with the second water outlet 340 of the control valve 430, and the communication between the second joint 420 and the second water outlet 340 of the control valve 430 is cut off. When the control valve 430 is in the second state, the first water outlet 330 of the second joint 420 and the second water outlet 340 of the control valve 430 are communicated, and the communication between the first joint 410 and the second water outlet 340 of the control valve 430 is cut off.
Specifically, the first joint 410 is an internal thread and two external thread three-way joint, and the second joint 420 is an external thread right-angle two-way joint.
The operation of the line switching device 300 according to the embodiment of the present invention is described below.
As shown in fig. 3, when the control valve 430 is in the first state, the hot water flowing from the gas water heater 100 enters the pipeline switching device 300 through the first water inlet 310 of the first joint 410, because the control valve 430 is in the first state, the water flow at the first water outlet 330 of the second joint 420 is blocked, and cannot flow from the first water outlet 330 of the second joint 420 to the second water outlet 340 of the control valve 430, because of the pressure of the inner container of the electric water heater 200, the hot water at the first water inlet 310 of the first joint 410 cannot flow to the second water inlet 320 of the first joint 410, and the hot water at the first water inlet 310 directly flows out of the second water outlet 340. Therefore, when the gas-electric complementary hot water system 1 is in the gas-electric mode, the hot water generated by the gas water heater 100 can directly flow to the electric water heater side without the electric water heater 200, so as to realize the function of instantly outputting hot water.
As shown in fig. 4, when the control valve 430 is in the second state, the hot water flowing from the gas water heater 100 enters the pipeline switching device 300 through the first water inlet 310, and since the control valve 430 is in the second state, the water flow at the first water inlet 310 is blocked and cannot flow out from the second water outlet 340, the water flow directly enters the electric water heater 200 through the second water inlet 320, and the hot water flowing from the electric water heater 200 flows to the electric water end through the first water outlet 330 and the second water outlet 340 in sequence. Therefore, the pipeline switching device 300 can be switched back to the series operation in the electric-only mode or the electric-combustion combined mode of the electric-combustion complementary hot water system 1, so that the normal use of the electric-combustion complementary hot water system 1 is not influenced.
As shown in fig. 3 and 4, the control valve 430 is an internal thread three-way ball valve, and the control valve 430 includes a right-angle spool 431 and a three-way valve stem 432. The right-angle valve core 431 is provided with two right-angle valve core through holes 433, the central axes of the two right-angle valve core through holes 433 are perpendicular to each other, and the three-way valve rod 432 drives the right-angle valve core 431 to rotate so as to enable the control valve 430 to be switched between the first state and the second state.
In some specific examples of the present invention, as shown in fig. 2, in order to facilitate the connection of the second connector 420 with the electric water heater 200, the second connector 420 may be connected with the electric water outlet 220 of the electric water heater 200 through a corrugated tube 600.
Optionally, as shown in fig. 2, a three-way pipe 440 is connected to the second water outlet 340 of the control valve 430, one end of the other two ends of the three-way pipe 440 is connected to the outlet water temperature and flow sensor 900, and the other end is provided with a plug 441. Specifically, the three-way pipe 440 is an external thread three-way pipe, and the plug 441 is an inner hexagonal plug.
In some embodiments of the present invention, as shown in fig. 5-7, the line switching device 300 includes a first connector 410, a second connector 420, and a control valve 430. The control valve 430 may be a mechanical valve or an electric valve.
The first and second water inlets 310 and 320 are formed at the first joint 410 and communicate with each other. The first and second water outlets 330 and 340 are formed on the second joint 420 and communicate with each other. The control valve 430 is switchably connected between the first joint 410 and the second joint 420 between said first state and said second state. The outlet temperature and flow sensor 900 is connected to the second outlet 340 of the second joint 420.
When the control valve 430 is in the first state, the first water inlet 310, the second water inlet 320, the first water outlet 330 and the second water outlet 340 are communicated with each other. When the control valve 430 is in the second state, the communication between the first joint 410 and the second joint 420 is cut off.
Specifically, the first joint 410 and the second joint 420 are male three-way joints, respectively.
The operation of the line switching device 300 according to the embodiment of the present invention will be described with reference to the drawings.
As shown in fig. 6, when the control valve 430 is in the first state, the hot water flowing from the gas water heater 100 enters the pipe switching device 300 through the first water inlet 310, and the first water inlet 310 is conducted to the second water outlet 340 because the control valve 430 is in the first state. According to the law of fluid mechanics, the fluid always selects the flow channel with the least resistance to advance. The second water inlet 320 to the second water outlet 340 need to pass through the electric water heater 200, and the electric water heater 200 will generate a large water resistance, so the hot water at the first water inlet 310 directly flows out from the second water outlet 340. At this time, since the electric water inlet 210 of the electric water heater 200 does not feed water, and the hot water flowing from the first water inlet 310 to the second water outlet 340 will also generate a certain water resistance to the first water outlet 330, the water in the liner of the electric water heater 200 will not flow out from the electric water outlet 220. Therefore, when the gas-electric complementary hot water system 1 is in the gas-electric mode, hot water generated by the gas water heater 100 can directly flow to the electric water end without the electric water heater 200, and the function of instantly outputting hot water is realized.
As shown in fig. 7, when the control valve 430 is in the second state, the hot water flowing from the gas water heater 100 enters the pipeline switching device 300 through the first water inlet 310, and since the control valve 430 is in the second state, the water flow at the first water inlet 310 is blocked and cannot flow out from the second water outlet 340, and will directly enter the electric water heater 200 through the second water inlet 320, the water in the electric water heater 200 flows to the electric water end through the first water outlet 330 and the second water outlet 340 in sequence. Therefore, the pipeline switching device 300 can be switched back to the series operation in the electric-only mode or the electric-combustion combined mode of the electric-combustion complementary hot water system 1, so that the normal use of the electric-combustion complementary hot water system 1 is not influenced.
As shown in fig. 6 and 7, the control valve 430 is an internally threaded two-way ball valve, and the control valve 430 includes a straight spool 531 and a two-way stem 532. The straight spool 531 has two straight spool through holes 533, the central axes of the two straight spool through holes 533 are coincident with each other, and the two-way valve rod 532 drives the straight spool 531 to rotate, so that the control valve 430 is switched between the first state and the second state.
In some specific examples of the present invention, as shown in fig. 5, in order to facilitate the connection of the first joint 410 and the second joint 420 for water inlet with the electric water heater 200, the first joint 410 and the second joint 420 are respectively connected with the electric water inlet 210 and the electric water outlet 220 of the electric water heater 200 through a corrugated pipe 600.
In some specific examples of the present invention, as shown in fig. 2 and 5, an external leakage safety valve 700 is connected between the second water inlet 320 and the electric water inlet 210 of the electric water heater 200 to perform pressure relief when overpressure occurs, thereby improving safety.
Optionally, as shown in fig. 2 and 5, an inlet water temperature and flow sensor 800 is connected between the second water inlet 320 and the electric heating water inlet 210 of the electric water heater 200, and the inlet water temperature and flow sensor 800 is connected to the alarm device.
