In the present embodiment, the partitions 432 include two, which are first and second partitions 4321 and 4322, respectively, arranged in parallel and spaced apart, and each partition 432 extends in the radial direction of the body 431 or in a direction parallel to the radial direction, so that the air outlet passages 433 include three, which are arranged in parallel and spaced apart, and each air outlet passage 433 extends in the radial direction of the body 431 or in a direction parallel to the radial direction. The air outlet device 43 is disposed in the third air guiding duct 423, and at least part of the air outlet device extends downwards out of the third air guiding duct 423 and the bottom plate 15, so as to be exposed below the bottom plate 15.
In order to facilitate the rotation of the air outlet device 43, a track 44 is disposed in the third air guide tube 423, the track 44 is in a hollow cylindrical shape with openings at the upper and lower ends, the air outlet device 43 is partially disposed in the track 44, and the inner peripheral wall of the track 44 is adapted to the outer peripheral wall of the body 431 of the air outlet device 43 in shape and size. Two central symmetrical positions on the outer peripheral wall of the body 431 are respectively provided with a rotating shaft 434, the inner peripheral wall of the track 44 is provided with a rotating groove 441 which is recessed radially outwards, and the rotating shafts 434 can be placed in the rotating groove 441 to be mutually matched, so that the air outlet device 43 can rotate in the track 44. The height of the rail 44 is not less than the overall height of each of the air outlet passages 433 and the partition 432. Therefore, when the blowing mechanism 4 needs to be closed, two ends of the air outlet channel 433 correspond to the inner peripheral wall of the track 44 respectively, and two ends of the air outlet channel 433 are closed.

The body 431 is further provided with a second limiting protrusion 435 on the outer peripheral wall of the partition 432 and the air outlet channel 433 to limit the rotational limit position of the body 431.
The air blowing angles of the air outlet devices 43 of the two air blowing mechanisms 4 at the front side in the cavity 17 are deflected downwards in the vertical direction by 40-60 degrees from the lower plane of the smoke collecting cavity 16, and are deflected backwards by a certain angle horizontally from the front plane (the front side plate 13) of the smoke collecting cavity 16, such as deflected backwards by 30 degrees; the air blowing angles of the air outlet devices 43 of the two air blowing mechanisms at the rear side are deflected downwards by 40-60 degrees in the vertical direction from the lower plane of the smoke collecting cavity 16, and the horizontal direction is deflected forwards horizontally by a certain angle, such as 40 degrees forwards, from the rear plane (the rear side plate 13) of the smoke collecting cavity 16. The angle of the horizontal direction may be determined at the time of installation.
The horizontal direction of the blowing directions of the two blowing mechanisms 4 at the front side is fixedly deflected backwards by 30 degrees from the front plane of the smoke collecting cavity 16, so that the lampblack can be effectively gathered towards the center; due to the presence of the wall, which results in a coanda effect of the air flow, the horizontal direction of the blowing direction of the rear two blowing mechanisms 4 is set to be deflected forward by 40 ° fixedly from the front plane of the smoke collecting chamber 16.
When the blower mechanism 4 is not in operation, the deflection angle of the air outlet device 43 is 0 ° (e.g. the air outlet channel 433 is in a horizontal state), and the first limiting protrusion 4323 on the air outlet device 43 presses the pressure sensing element 45, so that the auxiliary fan 41 is not in operation, as shown in fig. 7. When the air outlet channel 433 of the manual air outlet device 43 deflects downward (e.g., the body 431 of the air outlet device 43 is rotated clockwise in a vertical plane), the first limiting protrusion 4323 leaves the pressure sensing element 45, and the auxiliary fan 41 starts to operate. The deflection angle of the air outlet channel 433 of the air outlet device 43 is limited to 40 ° -60 ° (the angle between the air outlet channel 433 and the vertical direction) by the rail 44 and the second limit protrusion 435. When the first limiting protrusion 4323 is matched with the uppermost limiting groove 442, the deflection angle of the air outlet channel 433 is 0 °; when the first limiting protrusion 4323 is matched with the middle limiting groove 442, the deflection angle of the air outlet channel 433 is 40 degrees; when the first limiting protrusion 4323 is engaged with the lowermost limiting groove 442, the deflection angle of the air outlet channel 433 is 60 °.
Under different use scenes, a user can manually adjust the blowing angle, for example, the left burner is used as a main cooking burner to set the following use scenes:
using scenario 1: referring to fig. 8, during cooking with big oil smoke on the left side, the air outlet channel 433 of the front left air outlet device 43 deflects 40 ° downwards, the air outlet channel 433 of the rear left air outlet device 43 deflects 40 ° downwards, at this time, the air outlet channel 433 is communicated with the inside of the third air guide duct 423, the air blown by the auxiliary fan 41 can be blown from one end of the air outlet channel 433 located in the third air guide duct 423 to one end located below the bottom plate 15 (towards the lower inner side of the range hood), and the front right and rear right air blowing mechanisms 4 do not work.
Using scenario 2: referring to fig. 9, during the left diffuse cooking (such as pancake, omelet, etc.), the air outlet channel 433 of the left front air outlet device 43 is deflected downward by 60 °, the air outlet channel 433 of the left rear air outlet device 43 is deflected downward by 60 °, and the right front and right rear air blowing mechanisms 4 are not operated.
Using scenario 3: referring to fig. 10, when cooking with big oil smoke on both sides, the air outlet channel 433 of the left front air outlet device 43 is deflected 40 ° downward, the air outlet channel 433 of the left rear air outlet device 43 is deflected 40 ° downward, the air outlet channel 433 of the right front air outlet device 43 is deflected 40 ° downward, and the air outlet channel 433 of the right rear air outlet device 43 is deflected 40 ° downward.
Using scenario 4: referring to fig. 11, during cooking (such as pancake, omelet, etc.) with diffuse small oil smoke on both sides, the air outlet channel 433 of the front left air outlet device 43 deflects 60 ° downward, the air outlet channel 433 of the rear left air outlet device 43 deflects 60 ° downward, the air outlet channel 433 of the front right air outlet device 43 deflects 60 ° downward, and the air outlet channel 433 of the rear right air outlet device 43 deflects 60 ° downward.
When the oil smoke is larger, the rising speed of the oil smoke is higher, so that the oil smoke can be effectively controlled only by a smaller downward deflection angle; when cooking produces diffuse small oil smoke (such as pancake, omelet, etc.), a large downward deflection angle is required to effectively control the downward extension of the area because the lower bottom surface of the smoke collecting chamber 16 is farther from the pan surface.
