Novel solar water heater

Abstract

The invention discloses a novel solar water heater. The novel solar water heater comprises a cylindrical water storage tank, a solar heat collector, a water inlet and outlet pipe and a supporting frame; the novel solar water heater further comprises a protection roller shutter, a rainwater sensor and an STM8S single-chip microcomputer; the bottom of the water storage tank is provided with protrusions connected with the solar heat collector and air exhaust openings; the cross section of the supporting frame is of an acute triangle structure, and the supporting frame is composed of support front legs, support back legs and a pressing plate; the protection roller shutter comprises a rolling shaft, a driving motor and a protection curtain; the STM8S single-chip microcomputer is arranged outside the water storage tank and is electrically connected with the driving motor, and the rainwater sensor is arranged above the pressing plate and is electrically connected with the STM8S single-chip microcomputer; and when the rainwater sensor senses rainwater, the driving motor is stated by the STM8S single-chip microcomputer, the rolling shaft is driven by the driving motor to roll, and therefore the free end of the protection curtain downwards stretches along the solar heat collector until a first magnet and a second magnet on the protection curtain are attached. The novel solar water heater is simple in structure, reasonable in design and long in service life.

Description

technical field [0001] The invention relates to the technical field of solar energy equipment, in particular to a novel solar water heater. Background technique [0002] Today, when the world's energy is in short supply, various renewable green energy sources have been developed and used by people. Solar energy, as the most widely distributed and relatively easy-to-develop resource, has long been used by people, such as drying clothes and drying food. , production of salt, etc., various equipment using solar energy emerge in endlessly today, and solar water heaters, as a common household equipment, have long been widely used by people to provide people with hot water in various seasons, saving a lot of disposable energy . However, the usual solar water heaters are designed to be inclined because the solar heating tubes are usually installed at the lower part of the water tank. The surface of the water inlet and outlet pipes makes it difficult for the accumulated water at t...

AI Technical Summary

Problems solved by technology

However, the usual solar water heaters are designed to be inclined because the solar heating tubes are usually installed at the lower part of the water tank. The surface of the water inlet and outlet pipes makes it difficult for the accumulated water at the bottom of the water tank to flow out, and it is easy to retain dirt

[0003] In addition, the existing solar water heaters are generally installed outdoors in various external environments. For example, when it rains, the heat collecting tubes of the solar water heaters are exposed to this environment for a long time, and it is easy to burst

Therefore, after the user installs the solar water heater, he will face the situation that the heat collecting tube bursts. Whether he uses solar energy frequently or occasionally, for the user, the choice is too small. Once installed, the solar water heater will appear. Heat collector burst problem
