[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-4 This utility model provides a technical solution: a centralized hot water supply device for high-rise buildings, including a frame 1, a first pump body 5, a second pump body 6, and a third pump body 7. A water softener 2, an electric boiler 3, and a water storage tank 4 are installed on the frame 1. The electric boiler 3 is powered by a solar panel assembly 8. The first pump body 5 is used to transport soft water, the second pump body 6 is used to transport hot water, and the third pump body 7 is used to transport return water. Temperature sensors 9 and safety valves 10 are installed on both the electric boiler 3 and the water storage tank 4. Both the electric boiler 3 and the water storage tank 4 include liquid level sensors to monitor the internal liquid level of the electric boiler 3 and the water storage tank 4. When the internal pressure of the equipment exceeds the set value, the safety valve 10 automatically opens to release pressure and prevent the equipment from bursting. The outlet of the water storage tank 4 is connected to a hot water supply pipe 41, and the hot water supply pipe 41 is provided with an insulation layer 42.

[0025] The water softener 2, electric boiler 3, water storage tank 4, and pump together constitute a hot water supply system. When applied to high-rise buildings, a zoned water supply system is adopted, with separate hot water supply systems for low, medium, and high zones, and independent circulation. This shortens the length of pipes when delivering hot water to high-rise buildings, reduces heat loss, and lowers water temperature fluctuations for high-rise users.

[0026] The insulation layer 42 is made of polyurethane foam. The insulation layer 42 is fitted on the outside of the hot water supply pipe 41 to insulate the hot water supply pipe 41, thereby further reducing heat loss and further reducing water temperature fluctuations for high-rise users.

[0027] A water softener 2 is added to the front end of the electric boiler 3. The water softener 2 removes calcium and magnesium ions from the water through ion exchange resin, thereby reducing the hardness of the water, reducing scale from the source, solving the scale problem, improving the heating efficiency of the equipment, reducing energy consumption, and extending the service life of the hot water supply device.

[0028] The electric heating element of the electric boiler 3 is an electromagnetic heating module. The photovoltaic panel of the solar panel assembly 8 converts solar energy into direct current, and the inverter converts the direct current into alternating current to power the electric boiler 3. The solar panel assembly 8 includes an energy storage battery to store excess energy to cope with nighttime or cloudy days. The electric boiler 3 and the solar panel assembly 8 are used together, which is efficient and environmentally friendly.

[0029] The water softener 2 includes a resin tank 21 and a brine tank 22. A control valve 23 is installed at the top of the resin tank 21. One end of the control valve 23 is connected to the tap water inlet pipe 24, and the other end of the control valve 23 is connected to the softened water outlet pipe 25. Tap water enters the water softener 2 through the tap water inlet pipe 24. The resin in the water softener 2 contains a large number of sodium ions. When hard water flows through the resin, the sodium ions on the resin exchange with the calcium and magnesium ions in the water. The calcium and magnesium ions in the water are adsorbed by the resin, and the released sodium ions do not form scale, thereby reducing the hardness of the water.

[0030] The resin tank 21 and the salt tank 22 are connected by a salt suction pipe 26. The salt tank 22 stores sodium chloride, which is dissolved into brine to rinse the resin during regeneration. When the resin is saturated with adsorption, concentrated brine is used to soak the resin to replace calcium and magnesium ions and restore the resin's adsorption capacity.

[0031] One end of the first pump body 5 is connected to the first delivery pipe 51, and the first delivery pipe 51 is connected to the soft water outlet pipe 25.

[0032] The other end of the first pump body 5 is connected to the second delivery pipe 52, which is connected to the water inlet of the electric boiler 3.

[0033] The first pump body 5 is used to transport soft water. After the tap water is softened by the water softener 2, it is discharged through the soft water outlet pipe 25. When the first pump body 5 is working, it draws soft water. The soft water enters the second conveying pipe 52 through the first conveying pipe 51, and then enters the electric boiler 3 through the second conveying pipe 52, where it is heated by the electric boiler 3 to form hot water.

[0034] One end of the second pump body 6 is connected to the third conveying pipe 61, and the third conveying pipe 61 is connected to the outlet of the electric boiler 3.

[0035] The other end of the second pump body 6 is connected to the fourth delivery pipe 62, which is connected to the inlet of the water storage tank 4.

[0036] The second pump body 6 is used to transport hot water. When the second pump body 6 is working, it draws hot water from inside the electric boiler 3. The hot water enters the fourth conveying pipe 62 through the third conveying pipe 61, and then enters the water storage tank 4 through the fourth conveying pipe 62. It is stored inside the water storage tank 4 and finally supplied to the user through the hot water supply pipe 41.

[0037] One end of the third pump body 7 is connected to the fifth delivery pipe 71, and the fifth delivery pipe 71 is connected to the return water port of the water storage tank 4.

[0038] The other end of the third pump body 7 is connected to the return water pipe 72, which is connected to the return water inlet of the electric boiler 3.

[0039] The temperature sensor 9 of the electric boiler 3 monitors the internal water temperature of the electric boiler 3 in real time and controls the electric heating element to heat the hot water to the specified temperature. The temperature sensor 9 of the water storage tank 4 monitors the internal water temperature of the water storage tank 4 in real time. When the temperature of the water inside the water storage tank 4 drops, the third pump 7 works, and the water enters the return water pipe 72 through the fifth delivery pipe 71 and flows back to the electric boiler 3 through the return water pipe 72 for reheating, thereby ensuring the hot water temperature.

[0040] In use, the water softener 2 is connected to the tap water pipe, and the solar panel assembly 8 powers the device. Tap water enters the water softener 2 through the tap water inlet pipe 24, and after being softened by the water softener 2, it is discharged through the softened water outlet pipe 25. When the first pump body 5 is working, it draws in the softened water, which then enters the second conveying pipe 52 through the first conveying pipe 51, and then enters the electric boiler 3 through the second conveying pipe 52. The electric boiler 3 heats the water to form hot water. When the second pump body 6 is working, it draws in the hot water from inside the electric boiler 3. The hot water enters the fourth conveying pipe 62 through the third conveying pipe 61, and then enters the water storage tank 4 through the fourth conveying pipe 62. The water is stored inside the water storage tank 4, and finally, hot water is supplied to the user through the hot water supply pipe 41. Temperature sensor 9 monitors the internal water temperature of electric boiler 3 in real time and controls the electric heating element to heat the hot water to the specified temperature. Temperature sensor 9 of water storage tank 4 monitors the internal water temperature of water storage tank 4 in real time. When the temperature of the water inside water storage tank 4 decreases, the third pump 7 works, and the water enters the return water pipe 72 through the fifth delivery pipe 71 and flows back to electric boiler 3 for reheating. The water softener 2, electric boiler 3, water storage tank 4 and pump together constitute a hot water supply system. When applied to high-rise buildings, a zoned water supply system is adopted, with separate hot water supply systems for low, middle and high zones, and independent circulation. This shortens the length of the pipeline when delivering hot water to high-rise buildings, reduces heat loss, and reduces water temperature fluctuations for high-rise users.
