Control method, circuit and device of electric fan and storage medium

Abstract

The embodiment of the invention discloses a control method, circuit and device of an electric fan and a storage medium, and relates to the technical field of power electronics, and the control method of the electric fan comprises the steps that a controller of the electric fan controls a driving mechanism of the electric fan to drive a head shaking mechanism of the electric fan to rotate; according to the current value collected by a current collection circuit of the electric fan, it is determined that the head shaking mechanism is locked; a corresponding angle when the head shaking mechanism is locked is determined; the corresponding angle when the head shaking mechanism is locked is determined as a reset angle; and the controller controls the driving mechanism to drive the head shaking mechanism to rotate according to the reset angle. The controller automatically judges whether the head shaking mechanism is locked or not according to the current value acquired by the current acquisition circuit, and determines the corresponding angle when the head shaking mechanism is locked as the reset angle according to the judgment result, so that the locked-rotor time of the head shaking mechanism is shortened, and the user experience is improved.

Description

technical field [0001] The present application relates to the technical field of home appliances, and in particular to a control method, circuit, device and storage medium of an electric fan. Background technique [0002] The electric fan is a commonly used electrical appliance in summer, and the electric fan generally includes a positioning system and a shaking head mechanism. The positioning system can realize the positioning of the oscillating head mechanism when it rotates in different angle ranges. When the positioning system recognizes that the oscillating head mechanism has rotated to the boundary position (ie, the set maximum oscillating angle), the oscillating head mechanism is turned back by resetting. [0003] In addition to the controller, the positioning system in the related art generally includes Hall sensors, magnets and the like. The positioning system in the related art has the following disadvantages: 1) Since Hall sensors and magnets are provided, the ci...

AI Technical Summary

Problems solved by technology

The positioning system in the related art has the following disadvantages: 1) Since Hall sensors and magnets are provided, the circuit structure of the positioning system will be relatively complicated, resulting in relatively high cost; 2) the electric fan should realize 30, 60, 90, For 120-degree rotation at equal angles, it is necessary to reset the initial position (0 degrees) first. During the reset process, the shaking head mechanism needs different stalling times at different positions, and the longest may need to be stalled for 15 seconds, which will cause electric shocks. The energy efficiency utilization rate of the fan is low; the locked-rotor will further increase the load on the gear, and if it is blocked for a long time, it will easily cause the abnormal sound of the shaking head mechanism
