As shown in fig. 1, the range hood includes a fume collecting hood 5, a fan system and a panel opening and closing structure, a fume collecting cavity is formed inside the fume collecting hood 5, and the moving panel 1 covers the fume collecting cavity when closed. Preferably, the motion panel 1 is articulated on the medial surface of collection petticoat pipe 5 through one or two bent block 2, and the motion panel 1 can open around the pin joint rotation and form the air intake for the oil smoke of suction and exhaust. The specific shape of the curved block 2 is not limited, and can be C-shaped, T-shaped and the like, and the curved block can support the motion panel 1 to move under the condition of being hinged, and can avoid the interference with the smoke collecting hood 5 and other structures in the process of moving.
As shown in fig. 2 to 8, the panel opening and closing structure of the range hood includes a moving panel 1, a driving device 3, and a curved block 2 connected to the moving panel 1, the driving device 3 includes a driving rod 31 capable of extending and retracting along a set direction, and the curved block 2 is hinged to a mounting surface (any structure capable of being used for hinging the curved block 2 may be the mounting surface, such as the smoke collecting hood 5); still include a connecting rod 4, the one end fixed connection of connecting rod 4 is on bent piece 2, and the end of actuating lever 31 is connected on connecting rod 4 and can follow connecting rod 4 and reciprocate. When the driving rod 31 moves, the connecting rod 4 and the crank block 2 can be driven to rotate around the hinge point together, so that the moving panel 1 is driven to close, and at least one stage in the closing process is that the closing speed is slower and slower, the stage can be a front stage, a middle stage and/or a rear stage of the closing process, preferably the rear stage, and the anti-pinch effect is good. The opening speed of the moving panel 1 is not limited, and it is preferable that the opening speed is increased at least at one stage in the opening process. The "movement" of the driving rod 31 includes, but is not limited to, extension and retraction of the driving rod 31 in a linear direction, and swinging around its root, and the linear extension is exemplified in the present embodiment.
In the present embodiment, the driving rod 31 can drive the moving panel 1 to close when extending, and the closing speed is slower and slower, and the closing speed of the moving panel 1 is slowest when the connecting rod 4 is parallel to the driving rod 31; in a similar way, when the driving rod 31 retracts, the connecting rod 4 and the crank block 2 can be driven to rotate around the hinge point together, so that the moving panel 1 is driven to open and the opening speed is faster and faster, and when the connecting rod 4 is perpendicular to the driving rod 31, the opening speed of the moving panel 1 is fastest.
The connecting rod 4 is fixed with the curved block 2, so the driving device 3 drives the moving panel 1 to open and close through the driving rod 31 and the integral structure of the connecting rod 4 and the curved block 2, the structure is simplified, the stroke and the static position of each part can accurately reach the design requirement, and the moving panel 1 is ensured to be accurately opened and closed in place.
