Description of drawings
Fig. 1 is the structural representation of water heater outlet pipeline cold water recycling device of the present invention;
Scheme of installation when Fig. 2 uses for water heater outlet pipeline cold water recycling device of the present invention.
The specific embodiment
Embodiment describes in further detail the present invention below in conjunction with accompanying drawing.
Embodiment one: as shown in Figure 1, water heater outlet pipeline cold water recycling device, comprise pressure water storage tank 1, control module 2, the hot water inlet pipe 15, hot water outlet pipe 14 and electric T-shaped valve 4, the bottom of pressure water storage tank 1 is provided with chilled water circuit water inlet pipe 12 and chilled water circuit outlet pipe 13, chilled water circuit outlet pipe 13 is provided with check-valves, the inlet of electric T-shaped valve 4 is connected with hot water inlet pipe 15, first outlet of electric T-shaped valve 4 is connected with chilled water circuit water inlet pipe 12, second outlet of electric T-shaped valve 4 is connected with hot water outlet pipe 14, hot water inlet pipe 15 is provided with temperature sensor 5, hot water outlet pipe 14 is provided with pressure sensor 6, the top of pressure water storage tank 1 is provided with air spring 8, the output of air spring 8 is provided with piston 9, the inner surface radial direction movable sealing of piston 9 and pressure water storage tank 1, between the bottom of piston 9 and pressure water storage tank 1, form pressure water storage district 10, the space size in pressure water storage district 10 is relevant with the position of piston 9, temperature sensor 5, pressure sensor 6 and electric T-shaped valve 4 are electrically connected with control module 2 respectively, pressure water storage tank 1 is provided with auxiliary pressure sensor 7, auxiliary pressure sensor 7 is electrically connected with control module 2, and the top of pressure water storage tank 1 is provided with passage 11.
Embodiment two: other structure is identical with embodiment one, and difference is that the end face of piston 9 is provided with cavity 91.
In the above embodiments, air spring 8 can substitute with mechanical spring or hydraulic spring grease cup.
Operation principle when water heater outlet pipeline cold water recycling device uses in conjunction with water heater as shown in Figure 2, chilled water circuit outlet pipe 13 is connected with an end of water pipe 18, the other end of water pipe 18 is connected on the cold water pipe 20, an end of heater inleting pipe 19 also connects on the cold water pipe 20, the water inlet end of cold water pipe 20 is provided with a control valve 22, hot water inlet pipe 15 is connected with an end of water heater outlet 17, hot water outlet pipe 14 is connected with water pipe 16, the water side of water pipe 16 is provided with hot water tap 23, and the water side of cold water pipe 20 is provided with cold water faucet 24.When water end 25 does not use hot water, hot water tap 23 closes, 6 measuring pressures of pressure sensor this moment equal the pressure of registering one's residence, and control module 2 control electric T-shaped valves 4 are opened to hot water outlet pipe's 14 directions, and this moment, water heater outlet pipeline cold water recycling device was in holding state.When water terminal 25 uses hot water, hot water tap 23 opens, 6 measuring pressures of pressure sensor this moment are near atmospheric pressure, the temperature that simultaneous temperature sensor 5 is responded to is lower than required hot water temperature, control module 2 control electric T-shaped valves 4 are opened to chilled water circuit water inlet pipe 12 directions, because pressure water storage tank 1 internal pressure is less than the feedwater pressure of registering one's residence, this moment, water heater outlet pipeline cold water recycling device was in the water-filling state.When the temperature of being responded to when temperature sensor 5 reached required hot water temperature, control module 2 control electric T-shaped valves 4 were opened the beginning hot-water supply to hot water outlet pipe's 14 directions.Simultaneously, because pressure water storage tank 1 internal pressure is greater than indoor pipeline hydraulic loss at this moment, pressure water storage tank 1 inner storing water is back to water system, reaches the purpose of reuse.In addition, when containing cold water in the pressure water storage tank 1, if open cold tap 24, then the cold water of Hui Liuing directly flows out by cold water faucet 24, can reach the reuse purpose equally.
If hot water tap 23 and cold water faucet 24 are opened simultaneously, then can directly reach the purpose of cold water recycling; And the structure of embodiment two can also guarantee when piston 9 arrives the bottom of pressure water storage tank 1, still can realize the purpose of cold water direct reuse.If the cold water in the pressure water storage tank 1 is full, 7 measuring pressures of auxiliary pressure sensor equal the pressure of registering one's residence, control module 2 control electric T-shaped valves 4 are opened to hot water outlet pipe's 14 directions, and water heater outlet pipeline cold water recycling device can temporary inefficacy, but it is minimum the probability of this situation to occur.
