Solar water heater with antifreezing function

Abstract

The invention discloses a solar water heater with an antifreezing function. The solar water heater comprises a water tank, solar heat collecting pipes, a supporting rack and a base and is characterized in that the base is provided with the supporting rack and the solar heat collecting pipe; the supporting rack is provided with the water tank; the water tank is connected with the solar heat collecting pipes; a water inlet pipe and a water outlet pipe of the water tank are provided with electromagnetic valves, non-return valves and three-way pipe sections; a reflecting plate is arranged below the solar heat collecting pipes; one end of the reflecting plate is arranged on the supporting rack, and the other end of the reflecting plate is arranged on the base. The solar water heater has the advantages that the sunlight utilization ratio is high, frost cracking of the water inlet pipe and the water outlet pipe can be effectively prevented, water resources can be saved, the use cost is lowered, and water is instantly hot when the solar water heater is turned on in a water utilization process.

Description

technical field [0001] The invention relates to a solar water heater with antifreeze function. Background technique [0002] At present, most of the solar water heaters used by people are connected to the water inlet and outlet pipes of the water tank. There is no antifreeze measure, and the water pipes are often frozen and cracked and need to be repaired. In addition, the hot water in the water pipes is stored in the pipes after use. The cold water is released and wasted, waiting for the hot water in the water tank to flow out. And solar water heater is owing to the needs of assembling, and certain space can be reserved between the solar heat collecting tubes, and these spaces are not utilized. Contents of the invention [0003] In order to solve the above-mentioned existing shortcomings, the main purpose of the present invention is to provide a practical solar water heater with antifreeze function, which has a high utilization rate of sunlight, and can effectively prev...
