Problems solved by technology

[0003] The main disadvantage of using an image sensor is that the dirt of the oil fume is likely to cause inaccurate or invalid detection results. A more effective measure is to design a high-transparency glass in front of the image sensor to prevent the oil fume from directly adhering to the surface of the sensor, but the glass surface will last for a long time Exposure to oil fume will also form dirt, so regular cleaning inspections and reminding users to clean and maintain are very important

Embodiment 1

[0091] Such as Figure 5-Figure 8 As shown, this embodiment describes the structure of the image acquisition device of the range hood.

[0092] The image acquisition device 100 of the range hood structure in the embodiment of the present invention is installed on the panel bracket of the range hood, embedded in the panel or installed on the inner bracket of the panel, wherein the image acquisition device 100 includes a sheet metal bracket 3 of the hood panel And hood control panel glass 2, image recognition camera 1 and camera protective glass 4 installed on the sheet metal bracket for protecting image recognition camera, also includes sensor protection air duct structure 5. The purpose of adopting this structure is to ensure that the sampling angle of view of the image acquisition device 100 is sufficient to cover the entire cooktop space. The advantage of installing through the installation guide groove 6 is that it is convenient for production and disassembly, and the appea...

Embodiment 2

[0101] Such as Figure 4 As shown, the range hood includes a hood control unit 200, an image acquisition device 100, a fan mechanism 300, a lighting control drive circuit 400, and an alarm reminder circuit 500, wherein the functions of each module are as follows:

[0102]Range hood control unit 200: range hood control circuit, responsible for the function operation of the range hood, signal acquisition and load control lights. First, the control unit communicates with the image acquisition device to realize self-inspection of the camera component, detection of oil volume in the oil collection box and acquisition The real-time oil fume concentration data calculates the corresponding function operation command and the air volume demand under the condition of oil fume concentration, and controls the fan to perform the oil fume suction function at a certain speed through the fan control circuit. When the image acquisition device detects that the oil collection box is full, the hoo...

Embodiment 3

[0114] This embodiment illustrates the working process of determining the range hood:

[0115] After the range hood is powered on, the image acquisition device performs a position self-inspection program to determine whether the camera 1 is at the zero angle position, which is the reset position. Figure 9 As shown, the reset position of the camera 1 is that the range hood is closed, the camera 1 is closed inside the range hood, and the camera 1 faces the positive direction of the x-axis. If the camera 1 is set at 0° at this time, the image acquisition device enters Camera cleaning detection program, otherwise the camera assembly will run position self-adjustment control, this control makes the camera 1 rotate from the positive direction of the x-axis to the positive direction of the y-axis, and when it rotates to the positive direction of the y-axis, the accumulated grease level of the oil collection box will be checked. Detection, set the camera 1 at the 90° position at this...

Abstract

The invention provides a detection and control method of a range hood and the range hood, and relates to the field of intelligent equipment detection. The method includes the following steps that theposition of an image acquisition device is controlled according to a user command or the running state of the range hood; when the image acquisition device is located in the first position, the imageacquisition device is used for acquiring image information in the cooking area, so that the smoke distribution condition in the cooking process is determined; when the image acquisition device is located in the second position, the image acquisition device is used for acquiring image information of an oil gathering box, so that the oil dirt liquid level accumulated in the oil gathering box; and when the image acquisition device is located in the third position, the image acquisition device is used for acquiring image information of a camera component, so that the dirt degree of the camera component is determined. The oil quantity of the oil gathering box is detected, the dirt condition of the camera component is detected, and the oil fume concentration of a stove is monitored in real time.

Description

technical field [0001] The invention relates to the field of intelligent equipment detection, in particular to a detection and control method of a range hood and the range hood. Background technique [0002] At present, the method of detecting the concentration of oil fume in the hood industry mainly uses sensors such as gas, dust, and optics, which have problems such as poor real-time detection, pollution of oil fume to the sensor, and difficulty in maintenance. The latest technology uses image recognition to detect lampblack, which can solve the above problems well. [0003] The main disadvantage of using an image sensor is that the dirt of the oil fume is likely to cause inaccurate or invalid detection results. A more effective measure is to design a high-transparency glass in front of the image sensor to prevent the oil fume from directly adhering to the surface of the sensor, but the glass surface will last for a long time Exposure to oily fumes can also cause dirt, so...
