36-volt safety voltage multi-source power supply low-temperature anti-scaling water heater

Abstract

The 36-volt safety voltage multi-source power supply low-temperature anti-scale water heater is an electric water heater which takes photovoltaic power as a main power supply and takes mains supply as an auxiliary power supply, and scale is reduced. In order to solve the problems of incrustation scale generation acceleration, hardening and electric leakage safety caused by 220 V high-temperature heating and the problem that the content of hot water cannot be clearly mastered after multiple times of water use, a 36 V safe voltage low-power electric heating ring is used for controlling the temperature to be 40-55 DEG C through a high-efficiency heat conduction rod to continue indirect heating; and meanwhile, the content of hot water can be mastered through a multi-layer water temperature display screen.

Description

Technical Field

[0001] The present invention designs a device that mainly generates electricity through photovoltaic / wind energy and supplemented by mains electricity. It is a water heater that indirectly heats the water through an external low-temperature heating high-efficiency heat conducting rod to reduce scale generation and leakage safety issues. Background Art

[0002] Traditional electric water heaters use high temperatures, which accelerate scale formation and hardening. The scale layer also hinders heat transfer, leading to localized overheating on the heating tube surface. Hardened scale creates an oxygen-deficient environment beneath the scale layer, inducing under-scale corrosion. Furthermore, current magnesium rod designs, which primarily prevent corrosion rather than directly remove scale, fail to remove hard scale. The resulting soft scale can cause itching and rashes in people with sensitive skin. Traditional electric water heaters mostly operate at 220 volts, and current leakage safety issues are significant in high-voltage environments. Summary of the Invention

[0003] This invention leverages the current development of clean energy sources such as photovoltaics and wind power, supplemented by mains electricity, to address the scale generation and treatment issues, as well as the safety issues of electrical leakage in conventional water heaters. This invention proposes a new, safe, low-temperature heating water heater with reduced maintenance costs and a longer lifespan. This invention primarily achieves this through the following scheme: The low-temperature, anti-scaling water heater features a hot water storage tank that indirectly heats a high-efficiency thermally conductive rod through an external low-voltage electric heating coil, reducing scale formation through low-temperature heating.

[0004] The advantages of the present invention include: It primarily utilizes clean energy sources such as photovoltaic and wind power, supplemented by mains electricity, which can save energy consumption. It also utilizes safe, low-voltage heating to avoid safety issues related to electric leakage. Low-temperature heating reduces the rate of scale formation, thereby reducing scale production. A low-voltage electric heating coil maintains the high-efficiency heat conducting rod at 40°C to 55°C. According to Arrhenius's law, the precipitation reaction rate increases by 2-3 times for every 10°C increase in water temperature. Maintaining the temperature at 40°C to 55°C can meet daily needs while ensuring that the scale production rate is not too high. Because the scale generation rate is reduced and the low temperature is guaranteed to reduce the hardening reaction and thus reduce under-scale corrosion, the present invention does not require magnesium rods, which reduces costs while avoiding water pollution caused by magnesium rods. The nano-ceramic coating on the heat storage tank and the high-efficiency thermal conductive rod is used to avoid the corrosion of the very little scale produced. Because the low-temperature hardening phenomenon is not obvious, the scale can be discharged through the sewage outlet or the cold water outlet, which greatly reduces the scale of the electric water heater. At the same time, the addition of a multi-layer water temperature display screen can also ensure that the hot water content and water temperature in the water tank can be mastered after multiple water uses. The use of the through-plate flange makes the replacement and maintenance of the thermal conductive rod more convenient, reducing maintenance costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0007] The present invention comprises a nano-ceramic-coated heat storage tank 1 into which a nano-ceramic-coated high-efficiency heat conducting rod is inserted via a through-disc flange 8. The nano-ceramic-coated heat storage tank 1 is connected to a hot water outlet 2, a cold water outlet 3, and a water inlet 6. After installation, a thermometer and a multi-layer water temperature display are connected.

[0008] After complete installation, open the water inlet 6 and add water to the nano-ceramic coating water storage tank 1. The low-voltage electric heating ring 5 heats the nano-ceramic coating high-efficiency thermal conductive rod to 40℃~55℃ to indirectly heat the nano-ceramic coating water storage tank. When the hot water temperature and hot water content meet the standards, the power will be automatically cut off. Open the hot water outlet 2 to let hot water flow out. The cold water outlet 3 is always open to ensure the outflow of cold water. At the same time, after multiple uses of water, the hot water content can be grasped through the multi-layer water temperature display screen 7.
