Description

Solar water heater easy to remove scale

Technical Field

The utility model relates to the technical field of solar water heaters, in particular to a solar water heater easy to remove scale.

Background

The vacuum tube heat collection type solar water heater is widely used in production and life. The lower end of a vacuum heat collecting pipe used in the conventional vacuum pipe heat collecting type solar water heater is a blind end, so that more scale (deposited at the bottom of the pipe, in a sheet shape or a fragment shape, and not attached to the pipe wall) is generated after long-time use, and the scale needs to be cleaned in time, otherwise, the use is influenced. When the scale is cleaned, the vacuum heat collecting pipes are detached one by one, then part of water is turned over and poured off, then the vacuum heat collecting pipes are turned over and shaken, then the vacuum heat collecting pipes are shaken while being turned over, and finally water is added to repeat the step of cleaning the scale. Therefore, the existing vacuum heat collecting pipe is not easy to clean and discharge after generating water scale, labor and time are wasted in disassembly and cleaning, the vacuum heat collecting pipe is easy to damage, and the service life of the water heater is seriously shortened. In many areas, especially in areas with high salinity water sources, the popularization and the application of the vacuum tube heat collection type solar water heater are influenced by water scale.
