Problems solved by technology

The fan blades of the ceiling fan are driven by the motor to make the surrounding air flow to generate wind, and the wind speed is determined by the speed of the fan blade rotation speed. The common ceiling fans on the market today generally use patch-type permanent magnet DC motors and use remote control. The control method is used to control the ceiling fan, and the circuit part of the motor, the

Abstract

The invention discloses a ceiling fan which comprises a hanging bracket, a hanging rod, a hanging handleless cup, a cover body, a motor, fan blades and a ceiling fan controller, wherein the ceiling fane controller comprises an MCU (Microprogrammed Control Unit), a wireless receiving unit, a rectification filtration unit, a DC/DC (Direct Current/Direct Current) converter, a motor driving unit, a voltage reversal detection unit and a PWM (Pulse-Width Modulation) controller, wherein the MCU is respectively connected with the wireless receiving module, the motor driving unit, the voltage reversal detection unit and the PWM controller; the MCU controller receives a control signal from the ceiling fan controller by virtue of the wireless receiving unit; the motor driving unit is connected with the motor and is capable of driving the motor; the voltage reversal detection unit is connected with the motor and is capable of feeding back a signal to the MCU; the rectification filtration unit is connected with the DC/DC converter and the PWM controller; the DC/DC converter is respectively connected with the MCU, the wireless receiving unit and the motor driving unit so as to perform operation power supply; the PWM controller is capable of supplying power to the motor by virtue of the motor driving unit.

Description

technical field [0001] The present invention relates to a ceiling fan. Background technique [0002] The ceiling fan can be hung on the ceiling to supply air to the indoor environment. It is a product with good heat-relieving function, energy saving and power saving, as well as decorative effect, and is very popular in the market. The fan blades of the ceiling fan are driven by the motor to make the surrounding air flow to generate wind, and the wind speed is determined by the speed of the fan blade rotation speed. At present, the common ceiling fans on the market generally use SMD permanent magnet DC motors, which use remote control. The control method is used to control the ceiling fan, and the circuit part of the motor, the remote control receiving part and other related functional circuits are usually independent and scattered in the ceiling fan. It is difficult, and the reliability is insufficient, and the cost is high, and the use is not humane enough. It can be seen ...
