Thereby ensuring that the two can synchronously rotate. Further, the left rotating part 41 and the right rotating part 42 can be moved in synchronization. When the motor rotates, the driving rod 413 and the driven rod 423 swing synchronously under the constraint of the synchronizing shaft 43, the panel lining plate 2 is pushed through the left connecting rod assembly 414 and the right connecting rod assembly 424, finally, the panel 3 rotates around the axis of the hinge 23, and the panel 3 is opened and closed freely.

In a preferred embodiment of the present invention, the center of gravity of the synchronizing shaft 43 is higher than the position of the center of gravity of the panel 3 to cancel the work of gravity of the panel 3 by the self-weight of the synchronizing shaft 43 when the panel 3 is opened, and the synchronizing shaft 43 is closer to the panel 3 than the motor to prevent the downward movement of the panel 3 when the panel 3 is closed.

As shown in fig. 3 and 4, since the panel 3 is turned upwards, the panel 3 needs to overcome its own weight when the panel 3 is opened due to its own weight, i.e., the gravity performs negative work. In order to make the panel 3 more easily open, the installation position of the synchronizing shaft 43 is separated from the rotation center by a certain distance to form a moment arm in the present scheme, and the self weight of the synchronizing shaft 43 makes the left and

right link assemblies

414 and 424 and the driving and driven

rods

413 and 423 form torque. That is, when the panel 3 is pushed open, the motor output torque and the torque generated by the own weight of the synchronizing shaft 43 act on the left and

right link assemblies

414 and 424 and the driving and driven

levers

413 and 423 at the same time, so that the panel 3 is pushed open more easily.

When the panel 3 is closed, the panel 3 rotates downwards quickly and quickly because the gravity of the panel 3 does positive work, at the moment, the synchronizing shaft 43 rotates around the center of the motor to do negative work and offsets the torque generated by a part of the panel 3 to the motor, so that the panel 3 can be prevented from being closed too quickly to generate blockage at the gravity reversing position of the panel 3, and the smoothness of the panel 3 in the closing process is promoted.

When the panel 3 is completely closed, the center of the synchronizing shaft 43 is located forward of the rotation center of the motor, and the driving rod 413 and the driven rod 423 tend to rotate counterclockwise due to the torque generated by the self weight of the synchronizing shaft 43 in a side view, so that the panel 3 is closed more tightly, and the panel 3 is prevented from being tilted.

In a preferred embodiment of the present invention, the panel lining board 2 comprises a side board 21 and an air inlet net 22 fixedly connected to the bottom side of the side board 21, two sides of the air inlet net 22 are solid bodies, and a grid is uniformly distributed in the middle to allow smoke to pass through, and oil drops are gathered in the solid bodies at two sides and do not fall into the grid.

As shown in fig. 1 and 2, when the panel 3 is opened, the left connecting rod assembly 414 and the right connecting rod assembly 424 are tilted forward, and the front ends of the left connecting rod assembly 414 and the right connecting rod assembly 424 are positioned above the air inlet, so that the surface condensed oil is easy to drip into the air inlet and directly drip onto the surface of the kitchen range. In the scheme, the left connecting rod assembly 414 and the right connecting rod assembly 424 are all arranged at the two sides of the shell 1, and oil drops of the left connecting rod assembly 414 and the right connecting rod assembly 424 lag behind and do not directly drop through the air inlet at the two sides of the air inlet.

In a preferred embodiment of the present invention, the panel 3 is a glass panel, the panel 3 is adhered to the outer side of the side plate 21, and the inner side of the side plate 21 is provided with a hinge 23 to be fixed to the upper side of the housing 1.

As shown in fig. 1 and 2, the connection between the panel liner 2 and the housing 1 by the hinge 23 allows the panel liner 2 and the panel 3 adhered thereto to be opened and closed. The rear side of the glass panel is provided with a panel lining plate 2, the left side and the right side of the top of the panel lining plate 2 are provided with hinges 23, and the other side of the hinge 23 is connected with the upper side position in front of the shell 1. I.e. the panel 3 can rotate freely around the centre of rotation of the hinge 23.

In a preferred embodiment of the present invention, the range hood further includes an oil cup 5, the oil cup 5 is disposed at the bottom of the housing 1, the housing 1 includes an obliquely disposed bottom wall, the housing 1 includes a bottom wall obliquely disposed in a front-rear direction, wherein a rear side of the bottom wall is connected to the oil cup.

As shown in figure 1, the bottom of the cigarette making machine is provided with an oil cup 5, and the panel lining plate 2 and the oil cup 5 are in inclined plane transition, so that interference with a pot in the cooking process due to the fact that the lower position of the shell 1 protrudes can be prevented. In addition, the condensed oil on the panel 3 and the panel lining plate 2 can flow into the oil cup 5 through the guidance of the inclined plane. When the panel 3 and the panel lining plate 2 are in an open state, the inclination angle of the air inlet net 22 is increased, but the rear end of the air inlet is still in the shell 1 of the range hood, condensed oil drops on the surface of the air inlet net 22 quickly flow to the rear end on the inclined surface and finally drop into the shell 1, and oil dropping at the air inlet is prevented.

The range hood of the utility model comprises a shell 1, a panel lining plate 2, a panel 3 and a rotating mechanism 4. The panel 3 is bonded on the panel lining plate 2 and can be opened and closed through the rotating mechanism 4, so that the front and back depth of the range hood is increased, and the smoke gathering effect is enhanced. And the rotation mechanism includes a synchronizing shaft 43, and the synchronizing shaft 43 increases the synchronicity of the driving link 413 and the driven link 423 and counteracts the work of the panel 3 itself by its own weight and the difference from the center of gravity of the panel 3 and the center of gravity of the motor.
