The driving member 27 rotates in a direction a as shown in fig. 3, when the first lever 281 acts on the contact block 719, the first lever 281 pulls the contact block 719 in a direction B as shown in fig. 3 away from the front panel 20, so that the contact block 719 drives the first slider 71 to move away from the front panel 20.

When the latch 712 is engaged, the first lever 281 drives the contact bevel 711 on the first slider 71 to disengage from the first guide surface 715, and the latch 712 is ineffective to lock the first slider 71, and the latch 712 can prevent the first slider 71 from being reset under the action of the second guide surface 716, so that the first slider 71 is kept away from the front panel 20

In another embodiment of the present invention, the contact block 719 is disposed on the opening and closing panel 30, and the driving element 27 is configured to drive the opening and closing panel 30 to move relatively, and the principle of the present invention is the same as that of the contact block 719 disposed on the first sliding block 71 in the foregoing embodiment, and is not described again.

Referring to fig. 10, fig. 10 is a schematic view of an installation structure of the lifting frame and the lifting mechanism of the present invention, in an embodiment of the present invention, the panel assembly further includes a lifting mechanism 40 and a lifting frame 60 connected to the lifting mechanism 40, the lifting mechanism 40 is configured to drive the lifting frame 60 to move along a second movement direction, and the second movement direction forms an included angle with the first movement direction; the opening and closing panel 30 is connected to the lifting frame 60.

When the driving member 27 drives the opening and closing panel 30 to move along the direction M1 in fig. 10, the opening and closing panel 30 moves out of the air inlet 22, as shown in the direction M1 in fig. 10 as the first moving direction, wherein the direction M2 is the second moving direction; the lifting mechanism 40 drives the lifting frame 60 to move along the direction M2 in fig. 10, so that the opening and closing panel 30 is moved away from the rear side of the air inlet 22, and at this time, the opening and closing panel 30 does not block the air duct corresponding to the air inlet 22 on the rear side of the front panel 20, so as to reduce the resistance of the opening and closing panel 30 to the air flow.

Taking the first movement direction as a horizontal direction as an example, the first movement direction may be perpendicular to the second movement direction, and after the opening and closing panel 30 is moved out of the air inlet 22, the lifting mechanism 40 drives the lifting frame 60 to move vertically, so that the opening and closing panel 30 moves upward or downward, and the opening and closing panel 30 is completely moved away from the air duct in the air inlet 22.

For example, when the second moving direction is perpendicular to the first moving direction, the opening and closing panel 30 moves to the first guide rail 70 and is far away from one side of the front panel 20, the lifting mechanism 40 drives the opening and closing panel 30 to move upwards, when the opening and closing panel 30 is located on the air duct at the rear side of the air inlet 22, the air flow enters the air duct at the rear side of the air inlet 22 from the air inlet 22, when encountering the rear end face of the chassis of the range hood 10, the end face is blocked and turns upwards, at the moment, the opening and closing panel 30 is located above the air duct, and when the turning air flow reaches the opening and closing panel 30, the air flow can be guided upwards under the action of the opening and closing panel 30 to prevent the air flow from generating vortex at the rear side of the front panel 20, so that the wind resistance of the air flow at the rear side of the front panel 20 can be reduced, contributing to improving the smoking amount of the range hood 10.

The second movement direction may also be arranged obliquely, and when the front panel 20 is in an oblique structure, the second movement direction may be made to be consistent with the oblique direction of the front panel 20, so that after the opening and closing panel 30 is moved out of the air inlet 22, the opening and closing panel 30 moves along the second movement direction along the oblique direction parallel to the opening and closing panel 30, so that the opening and closing panel 30 is moved away from the air duct inside the air inlet 22.

With reference to fig. 10, in an embodiment of the present invention, the panel assembly further includes a second guide rail 23, the second moving direction is parallel to the extending direction of the second guide rail 23, a second sliding block 24 is disposed on the second guide rail 23, and the lifting frame 60 is connected to the second sliding block 24; the opening and closing panel 30 is connected with the second slider 24, and the lifting frame 60 drives the opening and closing panel 30 to move through the second slider 24.

When the air inlet 22 needs to be closed, the lifting mechanism 40 moves in the reverse direction, the lock catch 712 opens, the lifting frame 60 moves in the reverse direction, at this time, because the lock catch 712 opens, the first slider 71 moves towards the direction close to the front panel 20, and under the action of the second elastic piece 718, the first slider 71 drives the lifting frame 60 to move downwards, so that the lifting frame 60 drives the opening and closing panel 30 to move downwards synchronously until the opening and closing panel 30 closes the air inlet 22.

When the opening and closing panel 30 moves to a preset height, the opening and closing panel 30 is parallel to the plane of the front panel 20, and when air enters the inner side of the front panel 20 from the air inlet 22, the air is not shielded by the front panel 20, so that the wind resistance caused by the front panel 20 can be reduced.
