Abstract
The present invention discloses an intelligent range hood and a control method thereof, which comprises a housing, a fan (), a smoke collecting hood (), a smoke guide plate (), a controller and a sensor () for detecting concentration of smoke and/or vapor inside or outside the housing. The sensor () outputs an electrical signal to the controller; and, the controller controls rotation speed of the fan motor () and position of the smoke guide plate () according to the signal received from the sensor (). The controller not only can automatically adjust the rotation speed of the fan motor () so as to allow the air volume of the fan () to adapt to the working condition of the range hood in real time, but also can adjust the air inlet area and the distance between the negative pressure region and the smoke source by moving the smoke guide plate () up and down, so as to adapt the change in the working condition.
