As shown in fig. 1, the movable smoke guide plate 2 includes plate bodies 20, 21, when the movable smoke guide plate 2 is in the closed state, the plate bodies 20, 21 are sequentially arranged along a first direction X and rotatably connected, a rotation center line O of the plate bodies 20, 21 is parallel to a second direction Y, and the second direction Y is perpendicular to the first direction X. The plate body 20 of the closed movable smoke guide plate 2, which is located at the upper end along the first direction X, can be turned upwards relative to the smoke collecting hood 1, so that the movable smoke guide plate 2 is switched from the closed state to the open state. The upward turning means: the plate body 20 is far away from the oil inlet 10 along the direction perpendicular to the first direction X and the second direction Y to expose the smoke inlet 10, and one end of the plate body 20 close to the plate body 21 along the first direction X moves in the direction far away from the ground along the height direction of the side-draft smoke extractor.
As shown in fig. 2 and 3, when the movable smoke guide plate 2 is in the open state, the folding is performed by using the rotation center line O of the plate body 21 as a folding line, so that the extending length L of the movable smoke guide plate 2 in the open state is reduced in the present embodiment, compared with the prior art in which the movable smoke guide plate is a whole plate. Thus, the occupied space of the movable smoke guide plate 2 is reduced, the cooking space range of a user is enlarged, and the oppressive feeling to the user during cooking and the possibility of collision between the user and the smoke guide plate are reduced. In the technical solution of the present invention, the protrusion length L of the movable smoke guide 2 refers to the maximum dimension of the movable smoke guide 2 in the direction perpendicular to the plane when the movable smoke guide is in the open state, and the plane is the plane of the movable smoke guide 2 in the closed state.
In the technical scheme of the invention, the folding of the movable smoke guide plate 2 by taking the rotation center line O as a folding line means that: as shown in fig. 2, the included angle between the plate bodies 20 and 21 on both sides of the folding line is greater than 0 degree and smaller than 180 degrees, i.e. the plate bodies 20 and 21 are arranged in an intersecting manner; alternatively, as shown in fig. 3, the plate bodies 20, 21 on both sides of the folding line are stacked in parallel.
Preferably, when the movable smoke guide 2 is in the open state, the plate bodies 20 and 21 on both sides of the folding line are stacked in parallel, because the structure of the movable smoke guide 2 is most compact, the occupied space is minimized, and the opposite surfaces of the plate body 20 and the plate body 21 are not polluted by contacting with oil smoke.
As shown in fig. 3, when the movable smoke guide plate 2 is in the open state, the angle of the plate bodies 20 and 21 relative to the smoke collecting hood 1 affects the smoke trapping effect of the movable smoke guide plate 2, and further affects the smoke extraction effect of the side draft range hood. It has been found that the movable smoke guide plate 2 has the best effect when the plate bodies 20, 21 are arranged perpendicular to the plane of the smoke inlet 10.
As shown in fig. 1, in the present embodiment, the plate bodies 20 and 21 are equal in size, so that the movable smoke guide 2 in the closed state is divided into two plate bodies uniformly along the first direction X. In a variation of the present embodiment, the sizes of the plate bodies 20 and 21 are not equal, so that the movable smoke guide plate 2 in the closed state is non-uniformly divided into two plate bodies along the first direction X.

Second embodiment
The difference between the second embodiment and the first embodiment is that: in the second embodiment, as shown in fig. 4, the movable smoke guide 2 further includes a plate 22, and when the movable smoke guide 2 is in the closed state, the plate 22 is located between the plates 20 and 21 along the first direction X and is rotatably connected to both the plates 20 and 21.
As shown in fig. 4 and 5, when the movable smoke guide 2 is in the open state, the folding is performed with the rotation center lines O of the plate bodies 20 and 22 as folding lines (i.e., the movable smoke guide 2 is folded with two rotation center lines O as folding lines), so that the plate bodies 20, 21 and 22 are stacked in parallel.
Referring to fig. 4 and 6, in the modified example of the present embodiment, when the movable smoke guide 2 is in the opened state, it is folded only with the rotation center line O of the panel 22 as a folding line, and the outer surfaces of the panels 20 and 21 are still on the same plane.
It should be noted that, in the technical solution of the present invention, the number of the plate bodies in the movable smoke guide plate should not be limited to the given embodiment. No matter how many the plate bodies are, as long as the movable smoke guide plate is in the opening state, the movable smoke guide plate is folded by taking at least one of the rotation center lines as a folding line, and the extending length of the movable smoke guide plate can be reduced. According to the change of the number of the plate bodies in the movable smoke guide plate, the structure of the driving control mechanism can be correspondingly adjusted on the basis of the embodiment, so that the folding and extending control of the movable smoke guide plate is realized.
Third embodiment
The difference between the third embodiment and the first embodiment is that: in the third embodiment, as shown in fig. 7 to 8, the side draft range hood further includes a moving panel 7 located in front of the smoke collecting hood 1, the moving panel 7 is movable along the slide rail 11 in the first direction X relative to the smoke collecting hood 1, and the plate body 20 of the movable smoke guide plate 2 is rotatably connected to the moving panel 7. When the movable panel 7 moves, the movable smoke guide plate 2 is driven to move so as to expose or shield the oil inlet 10.
The folding and the extension of the movable smoke guide plate 2 can be realized by the following two ways:
after the movable panel 7 is moved to the proper position, the plate bodies 20, 21 are rotated by the driving control mechanism 4 to fold or unfold the movable smoke guide 2.
The plate bodies 20, 21 are rotated by the drive control mechanism 4 while the moving panel 7 is moved, to fold or unfold the movable smoke guide 2.
In the present embodiment, the end of the plate body 21 away from the plate body 20 in the first direction X is not disposed in the slide rail 11, and when the movable smoke guide plate 2 is folded and extended, the end of the plate body 21 away from the plate body 20 in the first direction X is separated from the slide rail 11, and the movement thereof is not restricted by the slide rail 11.
In the present invention, each embodiment is written in a progressive manner, and the differences from the previous embodiments are emphasized, and the same parts in each embodiment can be referred to the previous embodiments.
Although the present invention is disclosed above, the present invention is not limited thereto. Various changes and modifications may be effected therein by one skilled in the art without departing from the spirit and scope of the invention as defined in the appended claims.
