Water-saving solar water heater

Abstract

The invention provides a water-saving solar water heater. The purpose of water conservation can be achieved by discharging cold water in an up-down water pipe to a water tank of the water heater first through either an air pressure method or a circulation method. The water tank is connected with the up-down water pipe, the up-down water pipe is connected with a shower hot water inlet pipe, the shower hot water inlet pipe is connected with a circulating water pipe through a micro water pump, and the circulating water pipe is connected with the water tank, so that a circulating system is formed. A micro air pump is connected with an air bubble. The air bubble is connected with the up-down water pipe through an air valve. The air valve can automatically control to open or close according to the number displayed on a pressure gauge. By adopting the water-saving solar water heater, water is saved; and more importantly, the solar water heater enters thousands of homes without limitations of high-rises, and the water-saving solar water heater makes some contribution to low-carbon economy.

Description

technical field [0001] The invention relates to a solar water heater, in particular to a water-saving solar water heater. Background technique [0002] The solar water heaters on the market at present must first release the cold water in the water outlet pipe every time they are used. The lower the building residents are, the longer the pipeline will be and the more cold water will be discharged, which not only causes a lot of waste of water resources, but also causes the use The inconvenience, therefore directly affected the widespread use of solar water heaters. [0003] The invention discloses a water-saving solar water heater, aiming at providing a water-saving solar water heater with simple structure and obvious water-saving effect, which is not limited by multi-storey high-rise buildings. It uses air pressure method or circulation method to discharge the cold water in the water pipe to the water heater tank first, which saves water, and more importantly, opens the doo...
