Description

Technical Field

[0001] The utility model relates to the technical field of new energy equipment, and in particular to a solar water heater system using graphene for auxiliary heating. Background Art

[0002] The invention patent with publication number CN102478276A provides a method for combining a solar water heater with an energy-saving stove and a bathing system thereof. The technical solution is mainly to heat the water inside the energy-saving stove by the auxiliary heating function of the energy-saving stove. Since the energy-saving stove is connected to the pipeline, which is in turn connected to the water heater, the energy-saving stove heats the water in the entire system of the device. When using hot water, there is no need to wait for the cold water in the pipeline to be emptied, and hot water can be quickly obtained by turning on the faucet.

[0003] The cited patent document belongs to the same technical field as the present application. The technical problem solved by the patent is to solve the technical problem that a large amount of cold water retained in the pipeline needs to be discharged when the faucet is turned on, which causes a waste of water resources. Although the technical solution provided by the patent can solve the technical problem, it also has certain defects. The defects are as follows: Defect 1. The energy-saving stove heats all the water in the pipeline and solar water heater contained in the system. Since the amount of water in the whole system is relatively large and the specific heat capacity of water is also relatively large, it takes a lot of heat to heat the water body to make the water obtain a lower temperature rise. The heating time is relatively long, and the heat consumed by heating is also relatively large. The effect of auxiliary heating and warming the water body is not ideal. Defect 2. Since the amount of water heated by the energy-saving stove is relatively large, the temperature rises relatively slowly. In addition, there is no insulation measure for the pipeline in the patent. When the weather is cold in winter, the rising speed of the heated water temperature is not as fast as the speed at which the water temperature is forced to drop due to the cold, which greatly increases the possibility of ice and rupture of the pipeline. Therefore, it is necessary to provide a new technical improvement to solve the above technical problems. Utility Model Content

[0020] Embodiment: A graphene-assisted solar water heater system includes a water pipe 1, a solar water heater 6, and a water outlet pipe 15. The water pipe 1 is connected to a tap water source, and the water outlet pipe 15 is connected to a faucet. The solar water heater also includes a circulation valve 3, a heat preservation bucket 13, a water pump 8, and a graphene heating device 12. The circulation valve 3 is a three-way structure, one end of which is connected to the water pipe 1, and the other two ends are respectively connected to the solar water heater 6 and the heat preservation bucket 13 through water pipes; the water pump 8 is respectively connected to the solar water heater 6 and the heat preservation bucket 13 through water pipes; the heat preservation bucket 13 is connected to the water outlet pipe 15; and the graphene heating device 12 is connected to the heat preservation bucket 13. In this way, the installation of each component of the utility model is completed. The above-mentioned graphene heating device 12 has an effective total conversion rate of electric heat energy of more than 99%, and at the same time, the superconductivity of the special graphene material is added to ensure stable heating performance. However, the difference from conventional metal wire heating film is that the heating is stable and safe.

[0021] The working principle of this system is: in daily use, open the water supply valve, tap water with a certain water pressure flows into the water inlet of the solar water heater 6 through the pipeline, and the water tank of the solar water heater 6 is filled with water. The water outlet of the solar water heater 6 is connected to the insulation bucket 13 through the pipeline. The pipeline connecting the water outlet of the solar water heater 6 and the insulation bucket 13 is provided with a water pump 8, and the water pump 8 plays the role of pressurizing the water, so that the water can be smoothly transported to the insulation bucket 13. Since the insulation bucket 13 is connected to the water outlet pipe 15, the water pressure of the water outlet pipe 15 is also ensured, and the water outlet pipe 15 can fully discharge water to meet daily use. In winter or rainy days when the sunlight is insufficient, the graphene heating device 12 performs auxiliary heating on the water in the insulation bucket 13. The hot water in the insulation bucket 13 is released for use through the outlet pipe 15, ensuring that hot water is available at any time of the year, and the system can immediately obtain hot water by turning on the faucet, without the link of draining the cold water in the pipeline, saving water resources and time. At the same time, the hot water in the insulation bucket 13 can flow back to the upper water insulation pipe 5 through the circulating water pipe 9, avoiding the occurrence of the upper water insulation pipe 5 being frozen and cracked. The upper water insulation pipe 5 and the lower water insulation pipe 7 themselves have an insulation layer that has the effect of reducing the heat conduction speed between the water body in the pipe and the outside world, and have the dual functions of heat preservation and antifreeze.

[0022] Preferably, the water supply pipe 1 is equipped with a water supply valve 2. After opening the water supply valve 2, tap water with water pressure flows through the water supply pipe 1 and the water supply insulation pipe 5 in sequence and then is injected into the water tank of the solar water heater 6. After closing the water supply valve 2, the water supply is completed.

[0023] Preferably, the water pipe connected between the circulation valve 3 and the solar water heater 6 is a water supply insulation pipe 5. The water supply insulation pipe 5 is a pipe provided with a heat insulation layer.

[0024] Preferably, the water pipe connected between the circulation valve 3 and the heat preservation water bucket 13 is a circulation water pipe 9. The circulation water pipe 9 is a key component for achieving the antifreeze effect, and can return hot water to the water supply insulation pipe 5 through the circulation water pipe 9.

[0025] Preferably, the water supply insulation pipe 5 is installed with a first manual ball valve 4 .

[0026] Preferably, the water pipes connecting the water pump 8 to the solar water heater 6 and the heat-insulating water bucket 13 are down-water heat-insulating pipes 7 .

[0027] Preferably, the down-water insulation pipe 7 connected between the water pump 8 and the solar water heater 6 is installed with a second manual ball valve 16. The first manual ball valve 4 and the second manual ball valve 16 have the function of manually cutting off the flow of water in the pipeline. When the first manual ball valve 4 and the second manual ball valve 16 are closed during maintenance or replacement, it is convenient to disassemble the parts.

[0028] Preferably, the down-water insulation pipe 7 connected between the water pump 8 and the insulation bucket 13 is installed with a safety valve 11. The safety valve 11 has the function of regulating the water pressure in the insulation bucket 13 to avoid the negative impact of excessive pressure increase of the water pump 8 on the insulation bucket 13.

[0029] The water outlet pipe 15 is installed with a water flow switch 10 .

[0030] The bottom of the insulation bucket 13 is provided with a drain port 14. After a long time, a certain amount of impurities will be deposited at the bottom of the insulation bucket 13. After opening the drain port 14, the impurities in the insulation bucket 13 can be discharged, and the insulation bucket 13 is cleaned and maintained.
