Problems solved by technology

[0002] In modern life, many families use stoves for cooking, but none of the existing range hoods can monitor the stoves
The range hood based on visual detection is sensitive to changes in the smoke in the stove environment. At the same time, the gears of the range hood are switched frequently, and the motor of the range hood frequently shakes violently, which will cause poor user experience and affect the accuracy of visual detection.

Embodiment 1

[0058] A gear shifting method for range hoods with a visual detection module, such as Figures 1 to 2 As shown, a hood main body 4, a control device, a shiftable component and a visual detection module 1 for detecting the size of oil fume are provided, and the visual detection module 1 and the shiftable component are electrically connected to the control device.

[0059] The visual inspection module 1 and the shiftable assembly of the present invention are respectively assembled on the main body 4 of the cigarette machine. The control device is used to control the operation actions such as starting, closing or shifting of the range hood.

[0060] The visual inspection module of the present invention processes and serializes the collected initial images, sequentially processes the initial images of the subsequent frames and the initial images of the previous frames, and obtains the current concentration of cooking fume at the time when the initial images of each subsequent fram...

Embodiment 2

[0087] A method for shifting gears with a range hood with a visual detection module, such as Figures 4 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 is attached to the device main body 11 .

[0088] 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 .

[0089] The lens 131 of the visual detection unit 13 passes through the through hole of the air cavity unit 111 and faces upward.

[0090] The positive pressure part 12 is assembled above the wind cavity part 111 and the air outlet 1122 of the p...

Abstract

The invention discloses a gear shifting method for a kitchen ventilator with a visual detection module. A ventilator body, a control device, a gear shifting assembly and the visual detection module which is used for detecting the quantity of lampblack are arranged. The visual detection module and the gear shifting assembly are assembled on the ventilator body and are further electrically connectedwith the control device. The control device receives an external gear shifting instruction and further sends gear shifting signals to the visual detection module and the gear shifting assembly separately. The gear shifting assembly receives the gear shifting signal of the control device and achieves gear shifting. The visual detection module receives the gear shifting signal of the control deviceand stops collecting image signals by T seconds, and then the visual detection module collects the image signals again. According to the gear shifting method for the kitchen ventilator with the visual detection module, vibrations to the visual detection module by gear shifting of the kitchen ventilator can be avoided, and thus smoke detection accuracy is improved. A positive pressure part of thevisual detection module produces gas, and the gas flows past the surface of a camera lens of the visual module at a high speed, and therefore certain positive pressure is formed between the camera lens and smoke, and the smoke cannot make contact with the camera lens.

Description

technical field [0001] The invention relates to the field of range hoods, in particular to a gear shifting method for a range hood with a visual detection module. Background technique [0002] In modern life, many families use range hoods for cooking, but none of the existing range hoods can monitor the range hoods. The range hood based on visual detection is sensitive to changes in the smoke of the stove environment. At the same time, the gear of the range hood is frequently switched, and the motor of the range hood frequently shakes violently, which will cause poor user experience and affect the accuracy of visual detection. [0003] Therefore, aiming at the deficiencies in the prior art, it is necessary to provide a gear shifting method with a range hood with a visual detection module to solve the deficiencies in the prior art. Contents of the invention [0004] One of the objectives of the present invention is to provide a gear shifting method for a range hood with a ...
