Range hood control method, range hood control system and range hood

Abstract

The invention discloses a range hood control method, a range hood control system and a range hood. The range hood control method comprises the steps that whether the actual rotating speed V0 of a motor reaches a current target rotating speed V0 or not is judged, and if not, the time for supplying alternating current to the motor and the time for disconnecting the alternating current in one period are adjusted. The actual rotating speed V0 of the motor can reach the current target rotating speed V0 by adjusting the time for supplying the alternating current to the motor and the time for disconnecting the alternating current within one period, so that the rotating speed of the motor can be matched with current lampblack parameters and current environmental parameters of the range hood, stepless adjustment of the rotating speed of the motor is realized, and the user experience is improved. The invention further provides the range hood control system which comprises the motor, a Hall sensor, a switch driver and a rotating speed sensor, the Hall sensor, the switch driver, the motor and the rotating speed sensor are sequentially connected, and the rotating speed sensor is connected with the Hall sensor. The invention further provides the range hood, and the range hood control system is arranged on the range hood.

Description

technical field [0001] The invention belongs to the technical field of household electrical appliances, and in particular relates to a control method, a control system and a range hood. Background technique [0002] The range hood is a kind of daily kitchen appliance that purifies the environment. It is generally installed above the kitchen stove. Air. Specifically, the existing range hood includes a fume collecting hood and a chassis, the fume collecting hood is arranged at the bottom of the chassis, an air duct is provided in the chassis, the water outlet of the fume collecting hood communicates with the air inlet of the air duct, and a fan is arranged in the air duct , under the action of the fan, the fume collecting hood gathers the oil fume, the oil fume enters the fume collecting hood, enters the air duct from the air outlet of the fume collecting hood, and then discharges to the outside through the air outlet of the air duct; [0003] During the use of the range hoo...

AI Technical Summary

Problems solved by technology

[0003] During the use of the range hood, the concentration of oil fume and the ambient temperature are different at different times, and the air volume of the fan corresponding to different oil smoke concentration and different ambient temperature is different. Among them, the air volume of the fan is positively related to the motor speed of the fan. However, the range hood currently has fixed gears for air volume adjustment, and users cannot freely choose the appropriate gear for air volume adjustment. The fixed gear will have the current gear and the current concentration of oil fume and the environment in which it is located. The temperature does not match, resulting in insufficient smoking capacity for small gears, and loud noise for large gears, resulting in poor user experience
