Description

Technical Field

[0001] The utility model relates to the technical field of solar water heaters, in particular to a solar water heater with intelligent antifreeze function for upper and lower water pipes. Background Art

[0002] A solar water heater is a water heater that converts sunlight energy into thermal energy. A solar water heater can heat water from a low temperature to a high temperature, thereby meeting people's needs for hot water in life. With the development of society, the application of solar water heaters is becoming more and more extensive. When the temperature is low, the intelligent system in the solar water heater will stop pumping water into the solar water heater, thereby preventing the solar water heater from being frozen. However, when the upper and lower pipes of existing solar water heaters are connected, it is usually necessary to perform antifreeze treatment on the surface of the pipes. Generally, a larger protective pad is fixed on the pipe to achieve the antifreeze effect. When only the protective pads at the connection of the upper and lower pipes need to be replaced, the staff often need to replace all the protective pads together, which will increase the workload of the staff and is not conducive to use. Therefore, a solar water heater with intelligent antifreeze for the upper and lower water pipes is proposed. Utility Model Content
