Oil smoke condition automatic reorganization range hood

Abstract

The invention provides an oil smoke condition automatic reorganization range hood. A vision imaging module conducts continuous imaging on a target area of a cooking bench and transmits imaged picturesto a processing module. The processing module receives the imaged pictures transmitted by the vision imaging module and conducts processing on the imaged pictures to obtain the smoke concentration and area information. The processing module acquires a left picture corresponding to a current frame of the imaged picture as a left picture object, acquires a right picture corresponding to the currentframe of the imaged picture as a right picture object, extracts smoke characteristics of the left picture object and the right picture object correspondingly, conducts smoke grade judgment on the left picture object and the right picture object correspondingly and then conducts summarizing on the obtained smoke grade information of the left picture object and the right picture object to obtain the smoke information of the overall current frame of the imaged picture. The range hook provided by the invention can automatically recognize the oil smoke conditions and is accurate in reorganizationresult and small in calculated amount.

Description

technical field [0001] The invention relates to the technical field of kitchen oil fume treatment, in particular to a range hood for automatically identifying the state of oil fume. Background technique [0002] The kitchen is one of the necessary configurations at home, and the effect of kitchen fume treatment directly affects people's quality of life. Traditional range hoods are usually equipped with buttons to control the fan to extract air, and cannot automatically judge the oil fume above the stove. [0003] In the prior art, there are mainly infrared projection method and physical detection method for detecting the concentration of cooking fume. In the infrared projection method, one end emits infrared light and the other end receives it, and the concentration of oil fume is judged by the intensity of the received infrared light. Multiple infrared emitters need to be installed in different positions to ensure the relative accuracy of oil fume detection, the cost is h...

AI Technical Summary

Problems solved by technology

The physical detection method is similar to the principle of a smoke alarm. The concentration of oil fume is judged by detecting the number of floating particles in the air. However, this method has two disadvantages. One is that the detection can only be carried out when the oil smoke touches the alarm, and long-distance detection cannot be realized. ; Second, when the air is not oil fume but water mist, it cannot be detected
