The links and the panel 2 may be directly or indirectly connected.

The transmission mechanism further includes a first support bar 525, a second support bar 526, a first guide bar 527, and a second guide bar 528.

The end of the second lead screw 516 far away from the second motor 514 can be rotatably connected with the rear side of the panel 2. The first motor 513 is connected to the second slider 541 and can move along with the second slider 541 along the second lead screw 516, in this embodiment, the first motor 513 is disposed below the second slider 541, the first lead screw 515 upwardly passes through the second slider 541, the first lead screw 515 and the second slider 541 are smoothly connected or do not contact with each other, so that the second slider 541 is not driven to move when the first lead screw 515 is driven to rotate by the first motor 513. The first slider 540 is disposed on the outer circumference of the first lead screw 515, and is screw-coupled to the first lead screw 515, so that the first slider 540 can linearly move along the axial direction of the first lead screw 515 when the first motor 513 drives the first lead screw 515 to rotate about its axis.

One end of the first supporting rod 531 is rotatably connected to a position between the two ends of the first link 521, and the other end of the first supporting rod 531 is rotatably connected to the first slider 540. One end of the second supporting rod 532 is rotatably connected to a position between two ends of the second connecting rod 522, and the other end of the second supporting rod 532 is rotatably connected to the first slider 540.

The upper and lower ends of the first guide rail 529 are fixedly connected to the rear side of the panel 2, and the upper and lower ends of the second guide rail 530 are fixedly connected to the rear side of the panel 2.

In the present embodiment, the first guide 529 and the second guide 530 have a cylindrical shape, preferably a rectangular parallelepiped shape, so that the first guide 529 and the second guide 530 can be directly and fixedly connected to the panel 2 in a surface contact manner. Each of the first guide rails 529 is provided with a first guide rail groove 5291 on one side facing the first baffle 41, and the left and right ends of the first baffle 41 are respectively disposed in the first guide rail grooves 5291 and can slide relative to the first guide rail 5291.

The length direction of each guide rod is vertical to the rotating shaft of the corresponding connecting rod, and the length direction of each guide rod is vertical to the moving path of the corresponding baffle.

Referring again to fig. 1 and 2, the range hood further includes a smoke barrier 6 that can be turned over with respect to the panel 2, thereby opening or closing the air inlet 21 at the front side of the panel 2. The structure of the smoke baffle 6 and the driving mechanism of the smoke baffle 6 are the same as the prior art. Alternatively, the smoke barrier 6 may also translationally open or close the air inlet 21. Fig. 1 shows the smoke barrier 6 in a closed state, and fig. 2 shows the smoke barrier 6 in an open state.

This embodiment can realize the multiple air inlet state of air intake 21:

referring to fig. 2 and 3, under the condition that both sides of the dual-range are cooked, the smoke barrier 6 is opened, and at this time, both sides of the amount of oil smoke are large, the first baffle 41 and the second baffle 42 are in the initial state, the first baffle 41 and the second baffle 42 are both located below the air inlet 21, so that the air inlet 21 is in the completely opened state, the driving mechanism 51 is not started, the second slider 541 is located in the middle of the second lead screw 516, and the first slider 540 is located in the middle of the two baffles.

Referring to fig. 7 and 8, when the range hood is closed, the first motor 513 is started, so that the first slider 540 moves upward, thereby driving the upper ends of the first and

second support rods

531 and 532 to move upward, and the lower ends of the first and

second support rods

531 and 532 rotate toward the middle, thereby driving the upper end of the first link 521 to rotate upward and rightward, and the upper end of the second link 522 to rotate upward and leftward, so that the first and

second baffles

41 and 42 move upward at the same time, and the air inlet 21 is closed, thereby preventing oil smoke from flowing backward.

Referring to fig. 9 and 10, when cooking is performed on the right side of the dual-range cooking appliance, the smoke barrier 6 is opened, and at this time, the amount of oil smoke is larger on the right side, the second motor 514 and the first motor 513 of the driving mechanism 51 are both started, so that the second slider 541 slides rightward, and the first slider 540 slides upward, and thus, the second link 522 keeps the initial position still, and the first link 521 rotates upward and rightward under the driving of the first link 531, and the first baffle 41 is pushed upward, so that the corresponding first air intake area 211 is closed, so that the flow rate on the left side is reduced, the range hood is in a right-open state, and the air intake speed of the oil smoke on the cooking side on the right side is increased. Thereafter, if the initial state is required to be restored, the second motor 514 and the first motor 513 are simply required to be reversely rotated, and the second slider 541 and the first slider 540 are returned to the initial positions.

In this embodiment, only the above three states are shown, and in fact, due to the arrangement of the second lead screw 516 and the first lead screw 515, the first slider 540 can realize the movement in the transverse direction and the longitudinal direction, and under the electric action of the first slider 540, each support rod and each connecting rod perform corresponding movement, so that each baffle can intelligently move within a stroke range according to the oil smoke concentration condition, stay at any required position, and realize a plurality of baffle states.
