The invention discloses a hoisting control system of a sliding screen of a range hood. A controller is mounted on the sliding screen; a driving motor is fixed on a panel and is used for driving the sliding screen to do up and down reciprocating motion relative to the panel, so that an air inlet is opened or closed; an induction assembly is mounted on the panel; the induction assembly can be used for inducing the position of the sliding screen and sending a position signal G to the controller; in an up and down operation process of the sliding screen, the controller is used for detecting current value I1 of the driving motor in real time; the controller is used for controlling actions of the driving motor through the received position signal G of the induction assembly and the current valueI1 of the driving motor, and a self set procedure, so that stopping, starting and speed change of the movement of the sliding screen are controlled. According to the hoisting control system disclosedby the invention, the movement of the sliding screen of the range hood is rapidly started and slowly stopped, impacts are reduced and noises are reduced; meanwhile, the hoisting control system has ahand pinching prevention function when sliding off, is automatically and reversely raised when meeting resistance and is safe and reliable.
