Embodiment 1

[0091] Range hood with gesture control visual detection function, such as Figures 1 to 2 As shown, a hood main body 3 and a visual detection module 1 are provided. The visual detection module 1 is assembled on the hood main body 3 and the visual detection module 1 faces the corresponding area of ​​the cooker 6 . The main body of the cigarette machine is provided with a control device for controlling the operation of the main body of the cigarette machine. The control device is assembled on the main body of the cigarette machine and electrically connected with the visual detection module.

[0092] The visual detection module 1 is provided with a gesture recognition unit, and the gesture recognition unit is electrically connected with the control device 2 .

[0093] The gesture recognition unit recognizes the user's hand movement to obtain an adjustment instruction signal, and then transmits the adjustment instruction signal to the control device 2 .

[0094] The visual detect...

Embodiment 2

[0105] Range hood with gesture control visual detection function, such as Figures 3 to 5 As shown, other features are the same as in Embodiment 1, the difference is that the visual detection module 1 is provided with a device main body 11, a visual detection part 13 and a positive pressure part 12 to prevent oily smoke or water vapor from approaching the visual detection part 13, and the visual detection part 13 The positive pressure unit 12 and the positive pressure unit 12 are respectively attached to the device main body 11 .

[0106]The main body 11 of the device is provided with an air cavity part 111 , the visual detection part 13 is defined as upward toward the shooting area, and the visual detection part 13 is assembled below the wind cavity part 111 .

[0107] The visual lens 131 of the visual detection part 13 passes through the through hole of the wind cavity part 111 and faces upward. The positive pressure part 12 is assembled above the wind cavity part 111 and t...

Embodiment 3

[0114] A method for detecting oil fume concentration. The visual detection module 1 processes the initial image collected by an imaging device as a basis. The initial image is a grayscale image. The initial image is processed to obtain the current concentration of cooking fume at the moment of the initial image of each subsequent frame. Through this method, the oil fume concentration at the current frame time can also be obtained in real time, and the oil fume concentration of the current frame image at each time can also be monitored according to needs, providing a basis for the automatic smoking strength of the range hood.

[0115] Each time the initial image of the subsequent frame is processed with the initial image of the previous frame, the steps to obtain the current concentration of cooking fume at the moment of the initial image of the subsequent frame are as follows:

[0116] (1) performing frame difference processing on the initial image of the rear frame and the in...

Abstract

A range hood with a gesture control visual detection function is provided with a range hood main body and a visual detection module, and the visual detection module is assembled on the range hood mainbody and oriented towards a corresponding stove area. The range hood main body is provided with a control device used for controlling the operation of the range hood main body, and the control deviceis assembled on the range hood main body and electrically connected with the visual detection module. The visual detection module is provided with a gesture recognition unit, and the gesture recognition unit is electrically connected with the control device. The gesture recognition unit recognizes hand movements of a user, obtains an adjustment indication signal and then transmits the adjustmentindication signal to the control device. The range hood with the gesture control visual detection function does not need to be in direct contact, is not affected by environmental noise and can be controlled according to hand gestures of the user, and the intelligentization of the range hood is improved. A fume concentration detection method is hardly affected by the detection distance, non-contactreal-time detection of the fume concentration can be realized, and the method has the advantages of being high in accuracy and real-time performance.

Description

technical field [0001] The invention relates to the field of range hoods, in particular to a range hood with a gesture control visual detection function and a method for detecting the concentration of the range hood. Background technique [0002] In modern life, many families use stoves for cooking, but the existing range hoods are controlled by buttons or voice. Button-type range hoods must be in contact with the hood, which is easy to get hands dirty. The range hood controlled by voice is noisy when the range hood is running, which affects voice recognition and easily causes problems such as misoperation or non-response. [0003] Therefore, in view of the deficiencies of the prior art, it is necessary to provide a range hood with a gesture control visual detection function and a method for detecting the concentration of the lampblack to solve the deficiencies of the prior art. Contents of the invention [0004] One of the objectives of the present invention is to provid...
