[0027] A preferred embodiment of the present invention will be described in detail below with reference to the accompanying drawings.
[0028] Moreover, although there is a plurality of stoves in the home kitchen, there is only one suction port in the existing hood, and the position is fixed, and it is difficult to achieve a good suction effect according to the distinction position of different cookers.
[0029] Such as Figure 1-6 As shown in the present embodiment, a hood having a plurality of independently lifting suction exhaust ports is provided, and a plurality of cookers are drawn by a plurality of stoves, including the hood body 10, at least two air wind boxes mounted in the hood body. The body 20 is disposed at the bottom of the guide mold and communicates with the guide mold, and can drive the guide wind to extend the hood body to reach the hood body and enable the suction opening of the suction area. Component.
[0030] In the present embodiment, the guiding box has two, and is mounted in the inside of the hood, and the oil-proof area of ​​the two cookers is sucking.
[0031] The present invention passes through a plurality of can be lifted, and the corresponding suction port is separately smoked, respectively, the cooker's smoke-free smoke can be improved, and the suction cigarette effect is improved; and if a stove is not used, the stove The corresponding guiding casing does not extend and the suction mouth will not open, and all the negative pressure inside the hood can act on another suction opening, and the cigarette control is achieved.
[0032] Such as Figure 4 As shown, including a flip cover 23 provided on the front side of the guide shell, a rotational opening of a rotating opening of the flip cover, the rotation opening, and the flip cover, and when the flip cover is rotated, the suction port is formed.
[0033] The air-conditioning casing is surrounded by a guide mold rear cover 21, a guide mold front cover 22, a guide mold side cover, and a flip cover, and the flip cover is located at the lower portion of the front cover of the guide mold; The flip cover is flipped outward, that is, the lower portion of the flip cover towards the direction away from the flip cover, at which time the stripping cover is formed between the flip cover and the air conditioner.
[0034] Such as figure 2 As shown, including the camera 11, and a controller mounted on the hood body and toward the cooker; the camera, lift execution assembly, and rotation execution assemblies are connected to the controller signal.
[0035] There are also some hoods that can lift down, but their lifting stroke is fixed. This lifting structure is generally turned down to drop, down to the maximum position, and return to the initial position after shutting down, and does not differ because of different cookers Adjust the height and the adaptability is poor.
[0036] The present invention identifies by a camera and an existing cooker recognition algorithm, a smoke recognition algorithm, a small size of the cooker, and the size of the smoke; the different cookers is different, and the smoke position is also different. After identifying the stove, it can control the protruding height of the suction port. The suction port is located at the smoke position, and the smoking effect is improved; when the smoke is large, the flip cover can be controlled to a larger angle, expand the area of ​​the suction port, improve the smoking effect; and can be used in different cookers The smoke size is distinguished to the suction port on the plurality of air-conditioning cases, such as control the suction port size, and the suction port height; although in theory, the suction mouth is opened to the maximum, which is conducive to absorbing the smoke, but the present invention Has a plurality of suction ports, and because the negative pressure inside the hood is determined, the larger the suction port, the smaller the negative pressure can be used in the other suction mouth, and the present invention is used to identify the smoke size, control suction The wind has a corresponding size, thereby achieving a negative pressure on-demand, and can reduce the overall negative pressure of the hood, saving energy when necessary.
[0037] In this embodiment, the cooker recognition algorithm employed is a common target recognition algorithm, such as a FAST-RCNN algorithm, YOLO algorithm; the smoke recognition algorithm can employ CN111931658A (a cooking oil identification method) method, prior art can also be employed. Other smoke recognition algorithms; through the camera acquisition image, the identification algorithm runs on the controller and performs components and rotates the component output command to the lift execution component.
