Solar water heater

Abstract

The invention provides a solar water heater which is hardly influenced by weather changes, and is high in heat collecting efficiency and capable of being normally used under the condition of lack of light and achieving manual intelligent adjustment of the water temperature and the water quantity. The solar water heater comprises a solar water heater body (1) and a PLC intelligent control system (2). The solar water heater body (1) comprises a main water tank (3), vacuum superconduction pipes (4), a water inlet pipeline (5), a water outlet pipeline (21) and an auxiliary water tank (6). The main water tank (3) is divided into a plurality of independent small cavities (7) which are provided with independent pipelines (8) connected with the auxiliary water tank (6). The independent pipelines (8) are provided with valves (9). The vacuum superconduction pipes (4) are provided with condensation ends (10). The PLC intelligent control system (2) comprises a control chip (20), a water temperature sensor (11), a light sensor (12), an input setting unit (13), a water temperature adjusting unit (14) and a display unit (15).

Description

technical field [0001] The invention relates to the technical field of solar energy technology, in particular to a solar water heater. Background technique [0002] With the reduction of traditional energy sources and the increasingly prominent environmental pollution problems, abundant solar radiation has become the focus of people's increasing attention to energy issues due to its unique advantages of low cost and no pollution. Inexhaustible pollution-free, green energy. [0003] A solar water heater is a water heating device that uses the energy of the sun to heat water from a low temperature to a high temperature. The traditional solar water heater is composed of a heat collecting tube, a water storage tank, a bracket and related accessories. It is based on the principle that hot water floats up and cold water sinks. , using double-layer glass vacuum heat collecting tubes to store water inside and communicate with the internal structure of the water storage tank.
