Solar water heater with high utilization ratio of solar energy

Abstract

The invention provides a solar water heater with a high utilization ratio of solar energy. The solar water heater comprises a water storage barrel, a supporting rack, an electricity storage device, a heating controller, solar panels, a supporting device and an electricity generator, wherein the water storage barrel is mounted on the supporting rack; vacuum heating tubes are mounted on the water storage barrel; the electricity storage device and the heating controller are mounted on one side of the water storage barrel; the heating controller is connected with the electricity storage device; electrothermal tubes are mounted in the water storage barrel; the electrothermal tubes are connected with the heating controller; a temperature sensor and a light sensor are mounted on the water storage barrel. The solar water heater disclosed by the invention can automatically rotate according to the irradiating direction of sunlight, so that the maximum radiation rate of sunlight is guaranteed; therefore, the utilization ratio of solar energy is significantly increased; besides, the solar water heater can utilize wind energy to generate electricity, so that the defect that a conventional water heater cannot supply sufficient hot water in continuous rainy days is overcome; the electricity is supplied to the heating controller through the electricity storage device, and the water is heated, so that the influence of rainy days on the working stability of the water heater is reduced.

Description

【Technical field】 [0001] The invention relates to the technical field of solar energy equipment, in particular to the technical field of a solar water heater with high utilization rate of solar energy. 【Background technique】 [0002] The existing solar water heater is a device that directly converts sunlight energy into heat energy, and heats water from low temperature to high temperature to meet the needs of hot water in people's life and production. The existing solar water heater is divided into vacuum tubes according to the structure. Type solar water heaters and flat-plate solar water heaters, mainly vacuum tube solar water heaters, occupy 95% of the domestic market share. The direction of the solar energy is also constantly changing throughout the day. The existing solar panels are only fixed on a certain device. Such a solar energy utilization rate is very low, and its working reliability needs to be improved. High solar water heater. 【Content of invention】 [000...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to solve the problems in the prior art, to propose a solar water heater with high utilization rate of solar energy, which can overcome the defect that the traditional water heater cannot provide sufficient hot water in continuous rainy days, and can simultaneously use solar panels and vacuum heating tubes to The water in the water storage tank is heated, and the solar panel can convert excess solar energy into electric energy and store it in the power storage device, and the heating controller is powered through the power storage device, so that the electric heating tube on the heating controller is connected to the water storage tank Energy-efficient water is used for heating, which reduces the impact of rainy weather on the stability of the water heater, and can change with the direction of sunlight, which greatly enhances the utilization rate of solar energy
