Solar heater and electric power storage and supply control method for same

Abstract

The invention discloses an electric power storage and supply control method for a solar heater. The electric power storage and supply control method is applied to the solar heater which meets one of first-eighth claims, and includes S1, converting light energy into electric energy by the aid of a photoelectric conversion module when light is inputted; S2, enabling a power control module to control a mains supply circuit and a first storage battery set to open or close a first power supply circuit of an AD (analog-digital) conversion circuit, control a second storage battery set to open or close a second power supply circuit of the AD conversion circuit and control the photoelectric conversion module to open or close a first charging circuit of the first storage battery set and a second charging circuit of the second storage battery set according to electric signals inputted by the photoelectric conversion module and respective voltage conditions of the first storage battery set and the second storage battery set. The invention further discloses the solar heater.

Description

technical field [0001] The invention relates to the field of heaters, in particular to a solar heater capable of storing electricity and a power supply method thereof. Background technique [0002] Along with the raising of people's living standard, electric heater has been more and more subject to liking of people as winter household auxiliary heating appliance. Most of the electric heaters currently on the market are products with a single electric heating function. The heater basically needs to be turned on continuously when it is working, and its electricity consumption is much higher than that of other household appliances. The heating electricity bill in winter is also a considerable expenditure. Solar energy, as an emerging renewable energy, has been valued by researchers from various countries. [0003] However, the photoelectric conversion efficiency of solar energy is low. At present, most solar heaters on the market use the photothermal conversion method to dire...

AI Technical Summary

Problems solved by technology

[0003] However, the photoelectric conversion efficiency of solar energy is low. At present, most solar heaters on the market use the photothermal conversion method to directly use the thermal radiation of sunlight to heat the water tank. This method is greatly affected by seasons and weather, for example, summer sunlight The thermal radiation is strong, but the demand for heating is the smallest, and the heat energy is nowhere to be consumed through light-to-heat conversion; while in winter, when a large amount of heating is required, the sunlight is relatively weak, resulting in insufficient heating, and most equipment needs electricity To carry out auxiliary heating, the utilization rate of solar energy is not high; there are also some solar heaters that directly use photoelectric conversion, which do not have the function of storing electricity, resulting in waste of heat energy
