Problems solved by technology

However, this detection method can detect the concentration of smoke only when a large amount of smoke enters the smoke sensor, and there is a delay in detection and identification
[0006] Therefore, in related technologies, there is still a large room for improvement in the recognition of smoke by range hoods.

Abstract

An embodiment of the invention provides a method for identifying lampblack, a processor and a range hood, and belongs to the technical field of household appliances. The method comprises the steps that a real-time detection image is acquired; color values of each pixel point in the detection image in three color channels in an RGB color space are detected; the minimum value of three color values of each pixel point in the detection image is obtained; the minimum value of each pixel point in the detection image is compared with a first preset threshold value to determine the number of the pixel points of which the minimum values are greater than the first preset threshold value; and the lampblack amount in the detection image is determined according to the number of the pixel points of which the minimum values are greater than the first preset threshold value. According to method, the lampblack volume is identified by the aid of the image, identification can be carried out before the lampblack reaches the range hood, and the hysteresis caused by the fact that a smoke sensor can carry out identification only when the lampblack reaches the range hood is overcome.

Description

technical field [0001] The invention relates to the technical field of household appliances, in particular to a method for identifying cooking fume, a processor and a range hood. Background technique [0002] In modern life, the kitchen plays an increasingly important role in family life. With the development trend of smart life, kitchen appliances are becoming more and more intelligent and humanized. The range hood is an important part of kitchen appliances, and its intelligence also represents the intelligence level of the home. [0003] When the user cooks food in the kitchen, oil fume will be generated, which will not only affect the air quality of the home, but also affect the health of the user. In addition, oil fume is easy to adsorb on the surface of the object. When the oil fume is adsorbed on the surface of the object, it will cause the object to be dirty and difficult to remove. Generally, the user will install a range hood to suck the oil fume, so as to discha...
