It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, only some structures related to the present invention are shown in the drawings but not all structures.

The recognition of the size of the oil fume by the range hood is mainly realized by the image recognition module. The image recognition module may include an image processing main controller and a visual camera. The visual camera can collect the oil fume image, and then the image processing main controller processes the image into a corresponding The oil fume data is output, and the speed of the range hood fan can be controlled according to the output oil fume data. Among them, the size of the oil fume data directly determines the speed of the fan, and realizes the wind-following smoke function that the fan speed is high when the oil fume is large, and the fan speed is low when the oil fume is small.

At present, the single image recognition module has the following problems: one is misrecognition of gestures. For example, when cooking is not done or the temperature in the pot is not high enough to produce oily smoke, when there is a gesture of waving the arm quickly within the range of the visual camera, the image recognition module will misidentify the gesture as oily smoke, resulting in the output of oily smoke data , the fan starts up by mistake. The other is misrecognition of human shadow interference. For example, when there is no cooking or the temperature in the pot is not high enough to produce oily smoke, when there is a human figure shaking within the range of the visual camera, the image recognition module sometimes misidentifies the shaking of the human figure as oily smoke Occurs, resulting in oily fume numerical output, fan false start, resulting in poor user experience.
