Problems solved by technology

However, due to the uncertainty of oil fume drifting, there will be interference such as human hand shielding in practice, so it is necessary to install multiple infrared emitters at different positions to ensure relatively accurate oil fume detection, the cost is high, and the requirements for the installation location are relatively high. high
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

Embodiment 1

[0098] A range hood with a shockproof visual detection module, such as Figures 1 to 3 As shown, the main body of the hood and the anti-vibration visual detection module for detecting the size of the lampblack are provided, and the anti-vibration visual detection module is assembled on the main body of the hood.

[0099] The shockproof vision module includes a vision detection component 11 and a shockproof component 12, the vision detection component 11 is assembled with the shockproof component 12, and the shockproof component 12 is assembled on the main body of the cigarette machine. The anti-vibration assembly 12 of the present invention may be at least one of anti-vibration damper or spring. Specifically, the anti-vibration component 12 of this embodiment is a spring.

[0100] The anti-vibration assembly 12 can reduce detection noise or other vibration hazards caused by vibration.

[0101] The main body of the hood is provided with a control device and a timing device fo...

Embodiment 2

[0115] A range hood with an anti-shock visual detection module, other features are the same as those in Embodiment 1, the difference is that the anti-shock visual module 1 of the present invention is an anti-shock visual module 1 for image filtering and denoising.

[0116] The anti-vibration visual module 1 of the present invention can directly remove the noise generated by the image caused by the vibration through a filtering algorithm. It should be noted that the image filtering and denoising algorithm of the present invention is common knowledge, and those skilled in the art should know , which will not be discussed here. Therefore, the vibration of the anti-shock visual detection module 1 caused by the shifting of the range hood can be avoided, thereby improving the accuracy of smoke detection.

Embodiment 3

[0118] A range hood with a shockproof visual detection module, such as Figures 4 to 6 As shown, other features are the same as in Embodiment 1, the difference is that: the visual detection assembly 11 is provided with a device main body 111, a visual detection part 113 and a positive pressure part 112 to prevent oily smoke or water vapor from approaching the visual detection part 113, and the visual detection part 113 The positive pressure unit 112 and the positive pressure unit 112 are respectively attached to the device main body 111 .

[0119] The main body 111 of the device is provided with an air cavity part 1111 , and the visual detection part 113 is defined as upward toward the shooting area, and the visual detection part 113 is assembled below the wind cavity part 1111 .

[0120] The lens 1131 of the visual detection part 113 passes through the through hole of the air cavity part 1111 and faces upward.

[0121] The positive pressure part 112 is assembled above the wi...

Abstract

The invention provides a range hood with a shock-proof visual detecting module. The range hood is provided with a range hood main body and a shock-proof visual detecting module used for detecting thequantity of cooking fume, wherein the shock-proof visual detecting module is assembled on the range hood main body. The range hood with the shock-proof visual detecting module can prevent the gear shifting of the range hood from shaking the shock-proof visual detecting module, so that fume mist detecting accuracy is improved. The range hood has the advantages that the opening degree of a spoiler of the range hood main body is regulated according to the cooking fume quantity signal of a cooking bench corresponding zone, collected by the shock-proof visual detecting module, so that the size of an outer air inlet is regulated; and at the same time, the cooking fume suction speed also can be increased through a gear shifting assembly, and the intellectualization of the range hood is improved.The invention further provides a cooking fume concentration detecting method. The shock-proof visual detecting module uses the initial images of front and rear frames, collected by imaging equipment,as references for processing, and the initial images are gray scale maps. The range hood can realize the non-contact real-time detection of cooking fume concentration and has the advantages of high accuracy, real time and the like.

Description

technical field [0001] The invention relates to the field of range hoods, in particular to a range hood with an anti-shock visual detection module and a method for detecting the concentration of the range hood. Background technique [0002] In modern life, many families use stoves for cooking, but none of the existing range hoods can monitor the stoves, let alone shock-absorb the visual detection device. [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. However, due to the uncertainty of oil fume drifting, there will be interference such as human hand shielding in practice, so it is necessary to install multiple infrared emitters at different positions to ensure relatively accurate oil fume ...
