However, during the cooking process, there are usually interference factors such as changes in ambient light (such as turning on and off lights) in the cooking area, as well as moving interference factors such as arms, spatulas, moving pans, and placing pans, so that the oil fumes identified through the collected images The value cannot accurately represent the real amount of oil fume, so that the speed control of the hood is affected by interference factors, and the speed control is not accurate

The embodiment of the invention provides a rotating speed control method for a range hood and the range hood, and relates to the technical field of range hoods. The method comprises the steps of whena set of target area image is acquired each time, identifying an oil fume numerical value corresponding to each frame of the target area image in the set of target area image to obtain an oil fume numerical value set corresponding to the set of target area image; and determining rotating speed control strategies according to the change rule of the oil fume numerical value in the oil fume numericalvalue set, wherein the rotating speed control strategies comprise a first control strategy for cooking smoke and a second control strategy for interference items. By adopting the method, different control strategies can be adopted for the cooking smoke and the interference items, so that the influence, of the interfered oil fume numerical value, on the rotating speed of the range hood can be eliminated, and the rotating speed of the range hood can be controlled accurately.
Description
technical field [0001] The present application relates to the technical field of range hoods, in particular to a method for controlling the rotational speed of a range hood and the range hood. Background technique [0002] With the intelligent development of the hood, the hood can automatically adjust the speed of the hood according to the amount of fume in the cooking area, so as to remove the fume in time and save electricity. [0003] In the prior art, the hood is usually equipped with a camera for collecting images of the cooking area, and the soot value used to represent the amount of soot is recognized through the collected image, and then the speed of the hood is adjusted according to the value of the soot. For example, there is a positive correlation between the speed of the hood and the value of the oil fume, that is, the larger the value of the oil fume, the higher the speed of the hood, and the lower the value of the oil fume, the lower the speed of the hood.
