[0040] See also Figures 1 to 10 As shown, the embodiment of the present application provides a panel assembly for a smoke hood 10 provided with an air inlet 11, wherein the air inlet 11 extends along the length direction Y of the smoke hood 10, and the panel assembly comprises: two fixing members 100, which are arranged at opposite sides of the air inlet 11 along the length direction Y of the smoke hood 10 at intervals; a driving member 200, which is movably connected to the fixing member 100; a transmission assembly 300, which comprises a fixing part, a rotating part and a moving part which are rotatably connected in sequence, wherein the fixing part is arranged on the fixing member 100, and the moving part is connected to the output end of the driving member 200, and the transmission assembly 300 has an expanded state and a retracted state, and in the expanded state , the rotating part is located between the fixed part and the movable part, and in the retracted state, the fixed part is located between the rotating part and the movable part; and the opening and closing member 400 is connected to the rotating part; the driving component 200 drives the movable part to move in a direction close to the fixed part, so as to drive the rotating part to move to the side of the fixed part away from the movable part, so that the opening and closing member 400 moves toward the inside of the smoke hood 10 to open the air inlet 11; or, the driving component 200 drives the movable part to move in a direction away from the fixed part, so as to drive the rotating part to move to the side of the fixed part facing the movable part, so that the opening and closing member 400 moves in a direction close to the air inlet 11 to close the air inlet 11.

[0041] In the present embodiment, the opening and closing member 400 is flipped toward the inside of the air inlet 11 by the driving assembly 200 and the transmission assembly 300 so that the opening and closing member 400 is accommodated inside the smoke collecting hood 10, thereby preventing the opening and closing member 400 from extending out of the air inlet 11 and blocking the user's cooking view, and preventing oil smoke from gathering on the extended opening and closing member 400 to form condensed oil that is drained into the stove body or cooking utensils to contaminate the cooked food, thereby increasing the cooking view of the stove body and improving the cooking safety of the stove body. At the same time, the rotating part of the transmission assembly 300 is placed in the center, and after the opening and closing member 400 is accommodated in the smoke collecting hood 10, the central front panel can be turned inward and the oil guide tongue 410 at the rear can be turned outward, which can not only hide the central front panel and prevent the oil smoke from gathering and condensing on the central front panel, thereby improving the neatness and cleanliness of the appearance of the opening and closing member 400; but also guide and collect the condensed oil gathered on the upper edge of the air inlet 11, so that the collected oil stains can move to the inside of the range hood along with the opening and closing member 400 when the air inlet 11 is closed, and be processed inside the range hood, thereby improving the oil fume processing capacity and oil fume processing effect of the range hood.

[0042] Specifically, the panel assembly is configured as a composite component including at least two fixing members 100, a driving assembly 200, a transmission assembly 300 and an opening and closing member 400. The fixing member 100 can be a fixing plate structure approximately in a triangular shape, which can be vertically connected to both sides of the air inlet 11 of the smoke hood 10 by means of screws / bolts and the like, so as to form an installation inner angle for installing the driving assembly 200 and the transmission assembly 300 on the inner side of the opening and closing member 400, and the installation inner angle faces the air inlet 11; of course, the two fixing members 100 can also be connected to both sides of the air inlet 11 of the smoke hood 10 by means of welding and the like, and the connection method can be various and is not limited here; the fixing plate can be vertically connected to the inner wall of the air hood to form a quadrilateral structure with the driving assembly 200 and the opening and closing member 400, so as to improve the transmission stability on both sides of the opening and closing member 400. The driving assembly 200 can be a motor-driven structure, which can be driven by the motor to rotate the synchronous shaft to drive the moving part of the transmission assembly 300 connected to its output end to move. The transmission component 300 can be a connecting rod structure, and the two ends of its rotating part are respectively rotatably connected to the fixed part and the movable part, and the movable part is connected to the output end of the driving component 200. In this way, the position of the movable part can be moved by driving the driving component 200 to rotate, so that the movable part transmits the torque force from the driving component 200 to the rotating part, so that the rotating part and the movable part rotate relative to each other and change the spatial position of the rotating part; at the same time, the rotating part will not be separated from the control area of ​​the transmission component 300 under the action of the pulling force of the fixed part, thereby ensuring the spatial position stability of the rotating part after rotation, and ensuring the opening and closing stability and reliability of the panel assembly. The opening and closing member 400 can be a rectangular opening and closing panel, whose area size is slightly larger than the air inlet 11, so as to completely cover the air inlet 11; the tail end of the opening and closing member 400 is provided with a hook-shaped oil guide tongue 410, and when the air inlet 11 is in an open state, the oil guide tongue 410 abuts against the upper end surface of the air inlet 11, so as to drain and collect the oil stains / oil droplets gathered on the upper end surface of the air inlet 11 into the smoke collecting hood 10, so as to prevent the oil stains / oil droplets from dripping onto the stove or cooking utensils under the action of their own gravity, causing pollution of the stove surface / cooking utensils.

[0043] In one example, if Figure 4 and Figure 5 As shown, the oil guide tongue 410 is provided with a plurality of dispersed circular holes, which are used to prevent oil droplets from staying on the oil guide tongue 410 for a long time, thereby improving the oil fume removal efficiency of the range hood.

[0044] like Figure 4 and Figure 5 As shown, in a possible embodiment, the oil guide tongue 410 includes a first tongue plate and a second tongue plate connected at an angle, the first tongue plate is connected to the rear end side of the opening and closing member 400, the first tongue plate extends in a direction close to the air inlet 11, and the second tongue plate extends in a direction away from the air inlet 11.

[0045] In this embodiment, the specific configuration of the oil guide tongue 410 is optimized. Specifically, the oil guide tongue 410 is configured as a composite component including at least a first tongue plate and a second tongue plate, and the first tongue plate and the second tongue plate are arranged in a V shape. When the air inlet 11 is in an open state, one end of the first tongue plate close to the second tongue plate abuts against the upper edge of the air inlet 11, the second tongue plate extends toward the inside of the air cavity, and the second tongue plate obliquely passes through the air inlet 11. A plurality of circular holes are arranged on the first tongue plate, and the oil droplets accumulated on the upper edge of the air inlet 11 sequentially pass through the first tongue plate and the circular hole into the inner cavity of the smoke hood 10, or the oil droplets accumulated on the upper edge of the air inlet 11 sequentially pass through the first tongue plate, the circular hole and the side of the second tongue plate facing the first tongue plate into the inner cavity of the smoke hood 10 to achieve collection. The V-shaped oil guide tongue 410 effectively improves the oil droplet collection function of the range hood, and effectively prevents oil droplets from dripping from the first tongue plate onto the stove surface.

[0046] like Figures 1 to 7 As shown, in a possible embodiment, the transmission component 300 includes a first transmission member 310, a second transmission member 320 and a third transmission member 330, one end of the first transmission member 310 is rotatably connected to the fixing member 100, and the other end is rotatably connected to the second transmission member 320; one end of the third transmission member 330 is rotatably connected to the output end of the driving component 200, and the other end is connected to the second transmission member 320; the opening and closing member 400 is connected to the second transmission member 320.

[0047] In this embodiment, the specific configuration of the transmission assembly 300 is optimized. Specifically, the transmission assembly 300 is configured as a composite member including at least a first transmission member 310, a second transmission member 320 and a third transmission member 330. The first transmission member 310 can be a plate-shaped transmission structure, one end of which can be rotatably connected to the fixed member 100 through a fixed shaft, and the other end can be rotatably connected to the second transmission member 320 through a connecting shaft; the second transmission member 320 can be a Z-shaped plate-shaped transmission structure, and the relative position between it and the first transmission member 310 and the third transmission member 330 can be variable, and the opening and closing member 400 changes its relative position relationship with the air inlet 11 as the position of the second transmission member 320 changes; the third transmission member 330 can be a plate-shaped transmission structure, one end of which can be rotatably connected to the second transmission member 320 through a connecting shaft, and the other end can be rotatably connected to the output end of the driving assembly 200 through a connecting shaft. In this way, the third transmission member 330 is driven to move through the driving component 200, and the second transmission member 320 is driven to rotate and move by the rotational torque force from the driving component 200 on the third transmission member 330, thereby changing the position of the second transmission member 320 and the angle between the second transmission member 320 and the third transmission member 330, and then the first transmission member 310 is driven to rotate and move by the rotational torque force from the third transmission member 330 on the second transmission member 320, thereby changing the position of the first transmission member 310 and the angle between the first transmission member 310 and the second transmission member 320, thereby realizing force transmission and displacement transmission between the driving component 200 and the transmission component 300, and then realizing the change of the position of the opening and closing member 400, and realizing the opening or closing of the air inlet 11.

[0048] It is understandable that, in the process of opening the air inlet 11, the upper angle between the drive assembly 200 and the third transmission member 330 becomes larger, the upper angle between the third transmission member 330 and the second transmission member 320 becomes smaller, and the upper angle between the second transmission member 320 and the first transmission member 310 becomes larger. The process of closing the air inlet 11 is the opposite of the opening process, and will not be described in detail here.

[0049] like Figures 4 to 8 As shown, in a possible embodiment, the second transmission member 320 includes a first connection portion 321, a transition portion 322 and a second connection portion 323, the first connection portion 321 and the second connection portion 323 are respectively connected to opposite sides of the transition portion 322, and the first connection portion 321 and the second connection portion 323 extend in opposite directions; the first transmission member 310 and the third transmission member 330 are arranged at intervals on the first connection portion 321, and the opening and closing member 400 is arranged on a side of the second connection portion 323 away from the transition portion 322.

[0050] In this embodiment, the specific configuration of the second transmission member 320 is optimized. Specifically, the second transmission member 320 is configured as a composite member including at least a first connection portion 321, a transition portion 322 and a second connection portion 323. The first connection portion 321 may be a square plate. Connection holes are provided on opposite sides of the first connection portion 321 along its own length. One connection hole may be provided. In this case, the first transmission member 310 and the third transmission member 330 are both rotatably connected to the second transmission member 320 through the connection hole. The first transmission member 310 and the third transmission member 330 are respectively located on the inner and outer sides of the second transmission member 320. The transmission area of ​​the first connection portion 321 is point-shaped. Two connection holes may also be provided. In this case, the first transmission member 310 is rotatably connected to the outer side of one end of the second transmission member 320 through one of the connection holes, and the third transmission member 330 is rotatably connected to the inner side of the other end of the second transmission member 320 through the other connection hole. At least part of the first connection portion 321 along its own length is used as a part of the transmission. The transmission area of ​​the first connection portion 321 is linear. The transition part 322 may be a square plate, which may be vertically connected to the bottom side of the first connection part 321; the transition part 322 may be arranged parallel to the plate surface of the opening and closing member 400, so as to provide the second connection part 323 with a horizontal installation distance close to the air inlet 11. The second connection part 323 may be a square plate, which may be vertically connected to the side of the transition part 322 away from the first connection part 321, and arranged opposite to the first connection part 321, so that the entire second transmission member 320 forms an approximately Z-shaped structure; the side of the second connection part 323 away from the transition part 322 may be connected to the back side of the opening and closing member 400 by welding or the like, so that the transmission movement of the transmission assembly 300 and the opening and closing movement of the opening and closing member 400 are in different vertical directions, so as to avoid mutual interference between the two movements and improve the reliability and stability of the panel assembly.

[0051] like Figures 4 to 7 ,and Fig. 9 As shown, in a possible implementation manner, the transmission assembly 300 further includes a base 340 , and the first transmission member 310 is rotatably connected to the fixing member 100 via the base 340 .

[0052] In this embodiment, the specific configuration of the transmission assembly 300 is further optimized. Specifically, the transmission assembly 300 is configured as a composite component including at least a first transmission member 310, a second transmission member 320, a third transmission member 330 and a base 340. The base 340 can be a square block structure, which is connected to the fixed plate by welding or other means, or can be connected to the fixed plate by fasteners such as screws / bolts. In this example, by adding the base 340, the connection tightness between the first transmission member 310 and the fixed member 100 can be strengthened. At the same time, the rotation reliability of the first transmission member 310 can be increased by the base 340, thereby improving the operation reliability of the transmission assembly 300.

[0053] like Figures 4 to 7 ,and Fig. 9 As shown, in a possible embodiment, the base 340 includes a seat body 341 and a connecting fold 342 arranged on the periphery of the seat body 341, the seat body 341 is connected to the fixing member 100 via the connecting fold 342, and a connecting protrusion and an avoidance notch are provided on the seat body 341. The connecting protrusion is located on the side of the seat body 341 away from the fixing member 100, and is used to connect the first transmission member 310; the avoidance notch faces the opening and closing member 400, and is used to avoid the oil guide tongue 410 on the opening and closing member 400.

[0054] In this embodiment, the specific configuration of the base 340 is optimized. Specifically, the base 340 is configured as a combined component including at least a base body 341 and a connecting fold 342.

[0059] like Fig.10 As shown, in a possible embodiment, the driving connecting member 220 includes a third connecting portion 221, a fourth connecting portion 222 and a fifth connecting portion 223, and the third connecting portion 221 and the fifth connecting portion 223 are arranged at intervals on opposite sides of the fourth connecting portion 222 along the length direction Y of the smoke hood 10, and the fourth connecting portion 222 extends in a direction perpendicular to the straight line of the length direction Y of the smoke hood 10; the third connecting portion 221 is connected to the output end of the driving member 210, the fourth connecting portion 222 is connected to the moving portion, and the fifth connecting portion 223 is connected to the transmission shaft 230.

[0060] In this embodiment, the specific configuration of the driving component 200 is further optimized.
