Solar water heater device

Abstract

The invention relates to the field of environmental protection and energy conservation, and discloses a solar water heater device. The solar water heater device comprises a control circuit arranged on the solar water heater device, a solar power generation plate and a storage battery connected with the solar power generation plate, wherein the control circuit is connected with the storage battery, so the device not only can convert solar energy into heat energy for heating water, but also can convert the solar energy into electrical energy which is stored in the storage battery; and when the light is insufficient, the storage battery can supply power to an electric heating temperature complementing device to complementarily heat the water in a heat insulation water tank, and other external power supply is not needed, so the device greatly saves electricity cost and is more energy-saving and environment-friendly. No matter whether the power fails, the power can be continuously supplied to the control circuit of the solar water heater through the storage battery, the external power supply for controlling automatic water inlet is not needed, and dry burning due to power failure is avoided; and the solar water heater device can be used during power failure or on cloudy days, and provides great convenience for users.

Description

technical field [0001] The invention relates to the field of environmental protection and energy saving, in particular to a solar water heater device. Background technique [0002] With the development of science and technology and the improvement of people's living standards, the use of water heaters is becoming more and more popular; and solar water heaters are more widely used due to their energy saving and environmental protection features. [0003] At present, the common solar water heaters are roughly divided into two types: one is the water heater in which the solar heat collecting vacuum glass tube is directly inserted into the insulating water tank; the other is the heat pipe pressure water heater. However, the disadvantage of the solar water heater in the prior art is that the mains are used to supply power to its control circuit, while the control circuit of the solar water heater controls its water intake into the thermal insulation water tank through power suppl...

AI Technical Summary

Problems solved by technology

But the weak point of prior art solar water heater is: all adopt mains to supply power to its control circuit, and the control circuit of solar water heater controls its water inflowing in the heat preservation water tank by power supply, with the benefit of solar energy will heat preservation The water in the tank is heated

[0004] In addition, the solar water heaters of the prior art run into a cloudy day and the water temperature is relatively low, making it inconvenient to take a bath.
