The front side of the housing 1 and the position corresponding to the lower panel 31 form an air inlet 11, and the air inlet 11 is arranged below the upper panel 2. The upper panel 2 and the housing 1 are fixedly disposed, and the lower panel 31 can be translated and rotated with respect to the housing 1 to open or close the intake vent 11. When the lower panel 31 is in the first position, the intake vent 11 is closed by the lower panel 31, and when the lower panel 31 is in the second position, the intake vent 11 is opened. The housing 1 further includes side plates 12 at left and right sides, and a top rear plate 13 disposed between the side plates 12, the top rear plate 13 includes a top plate 132 and a rear plate 131, and the top plate 132 and the rear plate 131 may be integrated or may be a separate structure connected together.
A fan frame 4 is arranged above the shell 1, and a fan system (not shown) is arranged in the fan frame 4, so that the range hood with the upper fan is formed. An oil cup 8 is arranged at the bottom of the shell 1 and used for collecting condensed grease. The upper end of the oil cup 8 is open, and the front side of the oil cup 8 covers the bottom of the shell 1, so that oil drops in the shell 1 can completely enter the oil cup 8. An oil leakage hole 16 is formed at the bottom of the shell 1 so that oil drops enter the oil cup 8 through the oil leakage hole 16.
Referring to fig. 2 and 3, in order to facilitate the automatic driving of the lower panel 31, a moving mechanism is disposed on a side of the lower panel 31 facing the inside of the housing 1, and includes a support beam 371 fixed in the housing 1, a driving mechanism 372, a lead screw 373, a connecting rod 374, a slider 375, a first rocking bar 376 and a second rocking bar 377.
The support beam 371 has both ends connected to the upper panel 2 and the rear panel of the top rear panel 13 of the housing 1. A drive mechanism 372, preferably an electric motor, is provided on the first rocker 376. The first rocking bar 376 is further provided with the screw rod 373, and the screw rod 373 and the first rocking bar 376 extend in the same direction. One end of the screw rod 373 may be directly or indirectly connected to the output end of the driving mechanism 372, so that the screw rod 373 can rotate around its axis under the driving of the driving mechanism 372. The outer circumference of the screw 373 is sleeved with a slider 375, and the slider 375 has an internal thread structure, so that when the screw 373 rotates, the slider 375 can linearly move along the axial direction of the screw 373.

That is, the first rocking lever 376 supports the rotation of the screw rod 373. Meanwhile, the sliding block 375 slides in the groove 3761, the groove 3761 also plays a role in guiding and limiting the sliding of the sliding block 375, and the sliding block 375 is prevented from protruding out of the first rocker 376 to cause instability of sliding action.
Two panel holders 312 are provided on one side of the lower panel 31 facing the inside of the casing 1, and the two panel holders 312 may be separate bodies or may be integrally formed by links such as tie bars. Two panel supports 312 are spaced above and below. The other ends of the first rocker 376 and the second rocker 377 are rotatably connected to the corresponding panel supports 312, wherein the first rocker 376 is connected to the panel support 312 located below, and the second rocker 377 is connected to the panel support 312 located above.
The rotational axes of the link 374, the first rocking bar 376 and the second rocking bar 377 extend in the left-right direction.
Only the driving end of the motion mechanism is shown in fig. 2, the driven end being similar in construction to the driving end except that the drive mechanism 372 is omitted.
Referring to fig. 1 and 2, when the range hood is in the closed state, the lower panel 31 is in the first position, the air inlet 11 is closed, and the slider 375 is at the uppermost end of the screw rod 373, so that the lower panel 31 is easily closed at this time. When the lower panel 31 needs to be opened, the driving mechanism 372 is started, the screw rod 373 is driven by the driving mechanism 372 to rotate, and then the slider 375 is driven to slide downwards, so that the connecting rod 374 is driven to rotate downwards (clockwise rotation is shown in fig. 2) around the position connected with the supporting beam 371, and meanwhile, the second rocker 377 rotates anticlockwise to provide power for opening the lower panel 31, so that the lower panel 31 is pushed forwards and upwards, and meanwhile, the first rocker 376 rotates anticlockwise around the connecting position with the supporting beam 371 until the lower panel 31 moves to the front side of the upper panel 2 and is located above the air inlet 11, and at the moment, the lower panel 31 is located at the second position to open the air inlet 11, which is shown in fig. 4 and 5.
The four-bar linkage mechanism is usually used in the field to open and close the lower panel 31, and considering the avoidance from the upper panel 2, the four-bar linkage mechanism has the disadvantages that the upper rocker (the second rocker 377) is long and complex in shape, and is unstable and easy to shake during the movement process. Therefore, in the invention, the length of the upper rocker can be shortened by adding the sliding block mechanism (the screw rod 373 and the sliding block 375) on the lower rocker (the first rocker 376), the shape is simple, and the moving stability is increased; the positions of the two rotating connection points of the lower panel 31 can be selected at will without considering the complexity of the upper rocker, and the lower panel 31 can be closed more easily when the distance between the two rotating connection points is larger and the distance from the edge position is closer.
Adopt the mechanism that lead screw 373 and slider 375 constitute, can make actuating mechanism 372 and lower panel 31 distribute in rotation connecting point 3762 both sides, form the lever, thereby actuating mechanism 372 can change the distance with the rotation connecting point 3762 of first rocker 376 according to the weight of lower panel 31 and change moment, rotation connecting point 3762 also can carry out different selections according to the gravity of lower panel 31 and actuating mechanism 372's weight, can utilize actuating mechanism 372's dead weight to reduce the resistance of panel 31 opening in-process down, be favorable to reducing the power of actuating mechanism 372, stability and reliability in the increase motion process.
The support beam 371 can support the weight of the lower panel 31, is an interface of each rod piece for controlling the motion track of the lower panel 31, is connected with the top rear plate 13 and the upper panel 2 of the shell 1, enhances the rigidity of the shell 1, and improves the anti-falling capacity in the transportation process.
When the lower panel 31 is in a closed state, the lower panel 31 of the lower panel 31 is flush with the upper panel 2 to form a large plane; after the movement mechanism is opened, the lower panel 31 firstly translates forwards and backwards upwards and rotates anticlockwise; when the lower panel 31 is moved to the fully opened state, it is positioned at the front side of the upper panel 2.
