Method and device for controlling range hood and range hood

The invention relates to the technical field of intelligent household appliances, and discloses a method for controlling a range hood. The range hood comprises an instant suction device used for increasing the smoke suction rate. The method comprises the following steps: acquiring smoke information of a cooking area associated with a range hood; determining a target operation mode of the instantaneous suction device according to the flue gas information; and controlling the range hood to execute a control strategy determined according to the target operation mode. According to the method, the smoke information of the cooking area associated with the range hood is obtained, and the instantaneous suction device is correspondingly controlled according to the smoke information; therefore, even if a large amount of oil fume is generated in a short time in a specific cooking mode or in a specific cooking step, the diffused oil fume can still be sucked by controlling the instantaneous suction device, so that the oil
