Abstract
The utility model relates to a pipeline anti-freezing device of a solar water heater in winter. The pipeline anti-freezing device of the solar water heater in winter aims to solve the problem that a pipeline of an existing solar water heater which is commonly used in rural areas and low in cost is prone to being frozen and damaged in winter. Under the condition that an existing structure and arrangement of the pipeline of the solar water heater are not changed, according to two anti-freezing theories that water in the pipeline is made to flow and water in the pipeline is drained off, the purpose that water in a cold-water pipeline and a hot-water pipeline can flow from time to time can be achieved due to the fact that a temperature control valve is additionally arranged at the position of a cold and hot water mixing valve of the solar water heater so as to connect the cold-water pipeline and the hot-water pipeline. Meanwhile, the purpose that water in a mixed water pipeline is drained off is achieved by means of additional arrangement of a three-way valve at the position of a mixed water outlet of the cold and hot water mixing valve, and therefore anti-freezing of the pipeline of the whole solar water heater can be achieved.
