Abstract

The invention relates to a solar water heater, and provides a solar water heater with a self cleaning device. The solar water heater comprises a water tank and a heat absorber connected with the water tank, wherein the heat absorber comprises a transparent outer pipe and a heat collecting inner pipe, the heat collecting inner pipe is arranged in the transparent outer pipe, and the heat collecting inner pipe is connected with a circulation water opening of the water tank through a pipeline. The solar water heater is characterized by also comprising a hydraulic pump and a cleaning device, the hydraulic pump comprises a tubular casing, a rotating shaft and an impeller fixedly arranged on the rotating shaft, an inlet of the hydraulic pump is connected with the water inlet pipe, an outlet of the hydraulic pump is connected with a water inlet of the water tank, a rotating shaft of the hydraulic pump passes through the two ends of the casing, a sealing element is arranged between the rotating shaft and the casing, the rotating shaft is connected with the cleaning device through an active transmission mechanism, and the cleaning device transversely spans across the two sides of the heat absorber. The solar water heater has the advantages that the heat absorber of the solar water heater can be cleaned without increasing the new energy consumption, the structure is simple, the preparing cost is low, and the popularization and the application are convenient.

Description

technical field [0001] The invention relates to a solar water heater, in particular to a self-cleaning device of the solar water heater. Background technique [0002] Solar energy is both primary energy and renewable energy. It is rich in resources, can be used for free, does not need to be transported, and has no pollution to the environment. In the heat utilization of solar energy, the key is to convert the sun's radiant energy into heat energy. Since solar energy is scattered, it must be concentrated. [0003] Solar water heater is an important device to concentrate the sun's radiant energy, which can convert scattered solar energy into heat energy after being concentrated. [0004] A common solar water heater includes a water tank and a heat absorber connected to the water tank, the heat absorber includes a transparent outer tube and a heat collecting inner tube, and the heat collecting inner tube is arranged on the transparent In the outer tube, there is a vacuum be...
