AI Technical Summary
Technical Problem
When a range hood is working, it is difficult to balance noise and smoke extraction. Existing technology moves the motor from the air inlet area to the air outlet area, which reduces the smoke extraction effect.
Method used
Two impellers are installed in the range hood. One is installed in the air outlet area and connected to the motor, and the other is installed in the air inlet area and connected through a transmission mechanism. The motor speed is adjusted according to the resistance of the flue to balance noise and smoke extraction effect.
Benefits of technology
It reduces the noise perceived by users while improving the range hood's smoke extraction capacity, avoiding a decrease in smoke extraction capacity due to changes in the motor's position.

Abstract
The application belongs to the field of range hood, and discloses a control method and device of a range hood, computer equipment and a readable storage medium. The method comprises the following steps: acquiring a first motor rotating speed of a motor under the condition that the motor operates according to a reference current; determining a first fan wheel rotating speed of a second fan wheel according to the first motor rotating speed and a transmission ratio of a transmission mechanism stored in advance; inquiring a current corresponding to the first fan wheel rotating speed as a target current in a corresponding relationship between the current required by each flue resistance interval and the oil fume suction capacity of the fan wheel rotating speed interval, and controlling the motor to operate according to the target current. The application can enhance the oil fume suction capacity of the range hood.
