Water-saving anti-freezing solar water heater

Abstract

The invention discloses a water-saving anti-freezing solar water heater. The water-saving anti-freezing solar water heater comprises a water tank, a solar heat collecting pipe, a support and a base, and is characterized in that the support and the solar heat collecting pipe are arranged on the base, the water tank is disposed on the support, the water tank is connected with the solar heat collecting pipe, an electromagnetic valve, a one-way valve and a three-way pipe joint are disposed on a water inlet-outlet pipe of the water tank, a light reflecting plate is arranged below the solar heat collecting pipe, one end of the light reflecting plate is disposed on the support, and the other end of the light reflecting plate is disposed on the base. According to the water-saving anti-freezing solar water heater, the sunshine utilization rate is high, the water inlet-outlet pipe can be effectively prevented from being frozen and cracked, water resources are saved, usage costs are reduced, and hot water can flow out when a user opens the electromagnetic valve.

Description

technical field [0001] The invention relates to a water-saving and antifreeze solar water heater. 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 water-saving antifreeze solar water heater, which has a high utilization rate of sunlight, and can effectively pr...
