Solar water heater cold water recovery device

Abstract

Disclosed is a solar water heater cold water recovery device. The solar water heater cold water recovery device comprises a solar water heating tank. A water inlet of the solar water heating tank is connected with a booster pump through a first water return pipe, the booster pump is connected with a water return tank through a second water return pipe, the water return tank is connected with a water usage terminal through a third water return pipe, a water outlet of the solar water heating tank is communicated with the third water return pipe through a hot water pipe, both the water return tank and the booster pump are located below the water usage terminal, and the booster pump is further connected with a controller through a wire. According to the solar water heater cold water recovery device, on the basis of the gravity principle, cold water in pipelines between a solar water heater and the water usage terminal is collected in the water return tank, then the water collected in the water return tank is added to the solar water heating tank through the booster pump, and therefore the waste of water resources is reduced.

Description

technical field [0001] The invention belongs to the technical field of household articles and relates to a cold water recovery device for a solar water heater. Background technique [0002] Water is necessary for people's life and production activities. With the development of urbanization in our country, the amount of tap water in cities is increasing. Water is not inexhaustible, and there is a serious water shortage in most parts of northern my country, and water conservation must start from a little bit. With the improvement of my country's economic level, the utilization rate of solar water heaters is as high as 90%, which meets the needs of the people for bathing and washing with hot water for daily life, and improves hygienic conditions at the same time. When people use solar water heaters, they must first discharge the cold water in the pipes every time they use hot water, and then the hot water flows out, which not only causes waste of water resources, but also caus...
