Optionally, the first speed is a speed intermediate a highest speed and a lowest speed at which the oil network rotates. Therefore, under the condition that the cooking bench is in an open state, the oil screen directly rotates at the intermediate value rotating speed, and the oil screen has better oil smoke filtering capacity at the initial stage, so that the oil smoke is conveniently filtered, and the oil smoke filtering efficiency is improved.

Optionally, adjusting the rotation speed of the oil net according to the concentration of the oil smoke comprises: under the condition that the oil smoke concentration meets a first condition, the rotating speed of the oil net is increased; and/or reducing the rotation speed of the oil net or keeping the rotation speed of the oil net unchanged under the condition that the oil smoke concentration meets the second condition.
