Abstract

The invention relates to a hot water release control device for a solar water heater. The hot water release control device comprises a big cylinder and small cylinder combination body (1), a piston (2) is arranged in a big cylinder, an inner cavity of the big cylinder and small cylinder combination body (1) is divided into a water cavity and an air cavity, the sealed head of the big cylinder is provided with a connecting water pipe (3), a solar water heater water tank (4) is connected to the position, in front of a user faucet (5) and close to the faucet (5), of a main water inlet and outlet pipe through the connecting water pipe (3), a compression spring (6) is arranged in the air cavity and installed on a pressure regulation base (7), the outside of the air cavity is further connected with a vacuum pump (9) and an emptying valve (10), and the vacuum degree of the vacuum pump (9) is automatically controlled. According to the hot water release control device, cold water in the main water inlet and outlet pipe can be collected in the water cavity and then returned back to the solar water heater water tank through the compression spring, and therefore water is saved; the hot water release control device not only saves energy but also is simple in structure and convenient to use.

Description

technical field [0001] The invention relates to an improved invention of a water-saving structure for recovering cold water stored in the main water pipe of the solar water heater when the solar water heater releases hot water, in particular to a solar water heater water release control device. Background technique [0002] At present, with the improvement of people's living standards and the increasing awareness of safety and environment, solar water heaters are more and more popular among urban and rural residents as an energy-saving and safe product. However, since solar water heaters are generally installed on high places such as roofs, Only one main water inlet and outlet pipe is used, so when turning on the faucet during daily use of the water heater, the cold water remaining in the water inlet and outlet pipes must first be drained until hot water comes out. During this process, a large amount of cold water in the pipe is released, causing The waste of tap water is mo...
