Low-voltage solar ceiling fan for switching power supply through remote control

Abstract

The invention discloses a low-voltage solar ceiling fan for switching a power supply through remote control. The ceiling fan comprises a fan body and a remote control device, wherein the fan body comprises a driving power supply, a three-phase brushless direct-current motor and fan blades; the driving power supply comprises two ways of input and one way of output; one way of input is connected with a commercial alternating current after voltage reduction and rectification; the other way of input is connected with a solar low-voltage battery; the output of the driving power supply is connected with the three-phase brushless direct-current motor; a switching device of remote control actions is arranged between the two ways of input of the driving power supply and the output end; and the switching device controls the output end of the driving power supply to be switched and connected between the two ways of input. According to the low-voltage solar ceiling fan, two ways of input of the driving power supply are adopted, and the ceiling fan can be connected with the commercial alternating current, and also can be directly connected with the solar low-voltage battery for electrifying; and the remote control device is used for switching the connected input of the power supply, so that the low-voltage solar ceiling fan is capable of saving energy, environment-friendly, convenient to use and practical.

Description

technical field [0001] The invention relates to a low-voltage solar ceiling fan with remote control switching power supply. Background technique [0002] As a new energy source, solar energy has the advantages of being non-polluting and inexhaustible, and can be directly developed and utilized without mining and transportation. In contemporary times, the traditional energy is showing a trend of depletion, and the development and utilization of solar energy has been paid more and more attention by people. In some developing countries with energy shortages, solar energy has even entered ordinary households and been widely used. [0003] Small solar panels for households generally convert solar energy into 12V electric energy, while the working voltage of low-voltage motors used in existing ceiling fans is generally 24V. 24V, which increases manufacturing cost and weight of the ceiling fan. In addition, ceiling fans that only use solar energy are difficult to use normally in...
