Description

Technical Field

[0001] This utility model relates to the field of range hood technology, specifically to a smoke collection component and a range hood. Background Technology

[0002] Existing range hoods include a smoke collection assembly, which typically has a smoke collection chamber and a front panel. The front panel has a smoke inlet and a guide plate connected to it. The guide plate is a single piece that can open or close the smoke inlet. When the smoke inlet is closed, the guide plate prevents cooking fumes from entering the smoke collection assembly. When the smoke inlet is open, the guide plate guides the cooking fumes into the smoke collection chamber, allowing the range hood to extract the smoke.

[0003] However, when the smoke guide plate opens the smoke inlet, the entire plate rotates relative to the smoke inlet at a fixed angle. This makes it impossible for the smoke guide plate to be adjusted to collect smoke, and it can easily obstruct the user's view during cooking, increasing the possibility of the user colliding with the smoke guide plate and causing safety risks. Utility Model Content

[0004] In order to at least partially solve the problems existing in the prior art, according to one aspect of the present invention, a smoke collection assembly is provided, the technical solution of which is as follows.

[0005] The smoke collection assembly includes a cover, a first smoke guide plate, a first drive assembly, a second smoke guide plate, and a second drive assembly. The cover encloses a smoke collection cavity with a smoke inlet. The first smoke guide plate is rotatably connected to the cover. The first drive assembly is at least partially disposed within the smoke collection cavity and is connected to the first smoke guide plate, driving the first smoke guide plate to rotate relative to the cover to open or close the smoke inlet. The second smoke guide plate is rotatably connected to the first smoke guide plate. The second drive assembly is disposed on the first smoke guide plate and is connected to the second smoke guide plate, driving the second smoke guide plate to rotate relative to the first smoke guide plate.

[0006] The smoke collection assembly of this utility model has two aspects. First, the first and second smoke guide plates are controlled by separate drive components. The two smoke guide plates can be freely rotated, and the rotation angle can be adjusted according to the concentration of oil fumes to present different smoke guiding angles, smoke guiding dimensions, and smoke guiding distances. This can effectively guide the oil fumes to the smoke inlet, enhance the smoke guiding effect, and avoid obstructing the user's view during cooking, reducing the risk of the user colliding with the smoke guide plates and improving safety. Second, by setting the second drive component on the first smoke guide plate, the rotation efficiency of the second smoke guide plate relative to the first smoke guide plate is improved.

[0007] For example, the hood has a front panel, with the smoke inlet located on the front panel, and first smoke-gathering plates are respectively provided on the left and right sides of the front panel. This arrangement, with smoke-gathering plates on both sides of the smoke inlet, not only prevents the oil fumes from escaping to the side, but also improves the smoke collection efficiency of the smoke collection assembly.

[0008] For example, the first smoke-gathering plate is connected between the front side plate and the first smoke guide plate to form a foldable structure. When the smoke inlet is open, the first smoke-gathering plate is in an unfolded state; when the smoke inlet is closed, the first smoke-gathering plate is in a folded state. This design not only ensures that the first smoke-gathering plate effectively prevents oil fumes from escaping to the side, but also facilitates the storage of the first smoke-gathering plate, saving space.

[0009] For example, second smoke-gathering plates are connected to the left and right sides of the second smoke guide plate, respectively. When the smoke inlet is open, the second smoke-gathering plates are located outside the smoke collection chamber; when the smoke inlet is closed, the second smoke-gathering plates are at least partially located inside the smoke collection chamber. This arrangement, on the one hand, further enhances the effect of preventing oil fumes from escaping to the side and further improves the smoke collection efficiency of the smoke collection assembly; on the other hand, it facilitates the storage of the second smoke-gathering plates, thereby effectively saving space.

[0010] For example, along the length of the front panel, there is a distance L between the end of the first smoke-gathering plate and the end of the second smoke-gathering plate, where the distance L is 2mm to 5mm. This arrangement, with the distance L within this range, avoids interference between the first and second smoke-gathering plates during movement and ensures the smoke-gathering effect of both plates.

[0011] For example, the second smoke-gathering plate is fan-shaped. This configuration improves the smoke-gathering effect of the second smoke-gathering plate.

[0012] For example, a first hole is provided on the front side panel, and when the smoke inlet is closed, at least a portion of the second smoke-collecting plate passes through the first hole and is located within the smoke collection chamber. This arrangement not only facilitates the storage of the second smoke-collecting plate and avoids interference between the second smoke-collecting plate and the front side panel, but also saves space.

[0013] For example, the first driving assembly includes a first driving member, a first connecting rod, and a second connecting rod. Both the first driving member and the first connecting rod are disposed within the smoke collection chamber. The second connecting rod is connected to the first smoke guide plate, and the first connecting rod connects between the first driving member and the second connecting rod, with the first connecting rod and the second connecting rod being hinged together. This arrangement, on the one hand, reduces the space occupied by the first driving assembly outside the cover by placing both the first driving member and the first connecting rod within the smoke collection chamber, and avoids interference with the rotation of the first smoke guide plate; on the other hand, the hinged connection between the first and second connecting rods further improves the angular flexibility of the first smoke guide plate relative to the front side plate, ensuring that the first smoke guide plate can flexibly adjust its angle according to the concentration of oil fumes.

[0014] For example, the first link is constructed in an arc shape. This configuration provides a more uniform stress distribution, higher motion accuracy, and thus better drives the second link.

[0015] For example, a second hole is provided on the front side plate. When the smoke inlet is open, a portion of the second connecting rod extends out of the smoke collection chamber through the second hole. This arrangement avoids interference between the second connecting rod and the front side plate when the second connecting rod drives the first smoke guide plate to move.

[0016] For example, the second link has a first segment and a second segment. The first segment is hinged to the first link, and the second segment is connected to the first smoke guide plate. The first segment is inclined relative to the second segment. This arrangement allows the second link to better bear force to push and pull the first smoke guide plate, and also avoids interference between the second link and the front side plate during movement.

[0017] For example, a third hole is provided on the front side panel, through which the second drive assembly is located within the smoke collection chamber when the smoke inlet is closed. This arrangement avoids interference between the second drive assembly and the front side panel, and also saves space.

[0018] For example, the second drive assembly includes a second drive member, a third link, and a fourth link. The second drive member is disposed on the first smoke guide plate, the fourth link is connected to the second smoke guide plate, and the third link is connected between the second drive member and the fourth link, and the third link and the fourth link are hinged. This configuration, with the second drive member disposed on the first smoke guide plate and the third link and fourth link hinged, further improves the angular flexibility of the second smoke guide plate relative to the first smoke guide plate, ensuring that the second smoke guide plate can flexibly adjust its angle according to the concentration of oil fumes.

[0019] For example, along the length of the first smoke guide plate, the second drive assembly is positioned closer to the center of the first smoke guide plate than the first drive assembly. This arrangement, with the second drive assembly positioned closer to the center, helps maintain a uniform and stable thrust, thereby improving the rotational efficiency of the second smoke guide plate relative to the first smoke guide plate.

[0020] For example, the first smoke guide plate has a rotation angle α relative to the cover, where the rotation angle α is 0° to 150°. With this configuration, when the rotation angle α is within this range, the oil fumes can be effectively guided to the smoke inlet, ensuring the smoke guiding effect.

[0021] For example, the second smoke guide plate has a rotation angle β relative to the vertical line perpendicular to the first smoke guide plate, and the rotation angle β is 0° to 180°. With this setting, when the rotation angle β is within this range, it avoids obstructing the user's view during cooking, and can also effectively guide the oil fumes to flow to the smoke inlet.

[0022] For example, the first smoke guide plate has a first side that is away from the hood when the smoke inlet is open, and the second smoke guide plate has a second side opposite to the first side, which is connected to the first side by a flexible member. This arrangement fills the gap between the first and second smoke guide plates during rotation by the flexible member, thereby preventing the escape of fumes and further improving the smoke guiding effect.

[0023] According to another aspect of this utility model, a range hood is provided, including a casing, with a smoke collection assembly as described above connected to the bottom of the casing. The range hood of this utility model includes the smoke collection assembly as described above. Since the smoke collection assembly has the beneficial effects described above, the range hood including the smoke collection assembly as described above will necessarily also have the beneficial effects described above.

[0024] This utility model description introduces a series of simplified concepts, which will be further explained in detail in the detailed description section. This utility model description is not intended to limit the key features and essential technical features of the claimed technical solution, nor is it intended to determine the scope of protection of the claimed technical solution.

[0044] In the following description, numerous details are provided to enable a thorough understanding of the present invention. However, those skilled in the art will appreciate that the following description merely illustrates preferred embodiments of the present invention, which may be practiced without one or more of these details. Furthermore, to avoid confusion with the present invention, some technical features well-known in the art have not been described in detail.

[0045] To fully understand the embodiments of this utility model, a detailed structure will be presented in the following description. Obviously, the implementation of the embodiments of this utility model is not limited to the specific details familiar to those skilled in the art. Preferred embodiments of this utility model are described in detail below; however, in addition to these detailed descriptions, this utility model may have other embodiments.

[0046] This utility model provides a smoke collection assembly. The smoke collection assembly provided by this utility model can be applied to various types of range hoods, including but not limited to side-draft range hoods, top-draft range hoods, or hybrid top-draft and side-draft range hoods, etc. The following will describe in detail a smoke collection assembly according to an embodiment of this utility model with reference to the accompanying drawings.

[0047] See also Figure 1 , Figure 2 , Figure 3 and Figure 8 The smoke collection assembly 10 may include a cover 110, a first smoke guide plate 120, a first drive assembly 130, a second smoke guide plate 140, and a second drive assembly 150. The cover 110 may enclose a smoke collection cavity 112 having a smoke inlet 111. The first smoke guide plate 120 may be rotatably connected to the cover 110. The first drive assembly 130 may be at least partially disposed within the smoke collection cavity 112, and the first drive assembly 130 may be connected to the first smoke guide plate 120, driving the first smoke guide plate 120 to rotate relative to the cover 110 to open or close the smoke inlet 111. The second smoke guide plate 140 may be rotatably connected to the first smoke guide plate 120. The second drive assembly 150 may be disposed on the first smoke guide plate 120, and the second drive assembly 150 may be connected to the second smoke guide plate 140, driving the second smoke guide plate 140 to rotate relative to the first smoke guide plate 120.

[0048] The smoke collection assembly 10 of this utility model has two aspects. First, the first smoke guide plate 120 and the second smoke guide plate 140 are both controlled by separate drive components. The two smoke guide plates can be freely rotated, so that the rotation angle can be adjusted according to the concentration of oil fumes to present different smoke guiding angles, smoke guiding dimensions and smoke guiding distances. This can effectively guide the oil fumes to the smoke inlet 111, enhance the smoke guiding effect, and avoid obstructing the user's view during cooking, reducing the risk of the user colliding with the smoke guide plate and improving the safety of use. Second, the second drive component 151 is set on the first smoke guide plate 120, which improves the rotation efficiency of the second smoke guide plate 140 relative to the first smoke guide plate 120.

[0049] Specifically, the second smoke guide plate 140 can be hinged to the first smoke guide plate 120. Multiple hinges 160 can be provided between the first smoke guide plate 120 and the second smoke guide plate 140, allowing the second smoke guide plate 140 to rotate stably relative to the first smoke guide plate 120. Alternatively, the first smoke guide plate 120 and the second smoke guide plate 140 can also be connected by hinges or the like.

[0050] In some embodiments, two hinges 160 may be provided between the first smoke guide plate 120 and the second smoke guide plate 140, with the two hinges 160 respectively close to the left and right sides of the second smoke guide plate 140, so as to ensure the stability of the connection between the first smoke guide plate 120 and the second smoke guide plate 140.

[0051] See also Figure 2 and Figure 9 The cover 110 may have a front side plate 113. A smoke inlet 111 may be located on the front side plate 113. The smoke inlet 111 may be located in the middle of the front side plate 113 for better smoke collection. The number of smoke inlets 111 may be one or more, without specific limitation, as long as the smoke collection function of the smoke collection assembly 10 is guaranteed. First smoke-gathering plates 170 may be provided on the left and right sides of the front side plate 113 respectively. Thus, by providing smoke-gathering plates on both sides of the smoke inlet 111, not only is the fumes prevented from escaping to the side, but the smoke collection efficiency of the smoke collection assembly 10 is also improved.

[0052] Specifically, the first smoke guide plate 120 can be hinged to the front side plate 113. Multiple hinges 160 can be provided between the first smoke guide plate 120 and the front side plate 113, allowing the first smoke guide plate 120 to rotate stably relative to the front side plate 113. Alternatively, the first smoke guide plate 120 and the front side plate 113 can also be connected by hinges or the like.

[0053] In some embodiments, two hinges 160 may be provided between the first smoke guide plate 120 and the front side plate 113. The two hinges 160 are respectively close to the left and right sides of the first smoke guide plate 120 to ensure the stability of the connection between the first smoke guide plate 120 and the front side plate 113.

[0054] See also Figure 2 , Figure 12 and Figure 13 The first smoke-collecting plate 170 is connected between the front side plate 113 and the first smoke-guiding plate 120 to form a foldable structure. For example... Figure 9 With the smoke inlet 111 open, the first smoke-collecting plate 170 can be in the deployed state. For example... Figure 8 When the smoke inlet 111 is closed, the first smoke-gathering plate 170 can be in a folded state. The first smoke-gathering plate 170 can be folded into the smoke collection chamber 112. In some embodiments, the first smoke-gathering plate 170 can be made of a flexible material, such as a flexible soft rubber part, to achieve folding or unfolding of the first smoke-gathering plate 170. In embodiments not shown in the figure, the first smoke-gathering plate 170 can also be formed by multiple movable plates folding together, or multiple plates can be folded or unfolded by sliding members, etc., without specific limitations, as long as the first smoke-gathering plate 170 can be folded or unfolded and the smoke-gathering effect of the first smoke-gathering plate 170 is guaranteed. Furthermore, when the first smoke-gathering plate 170 is in the unfolded state, it can be fan-shaped, which improves the smoke-gathering effect of the first smoke-gathering plate 170. At this time, the radius of the fan shape of the first smoke-gathering plate 170 can be equal to the width of the first smoke guide plate 120. When the first smoke-collecting plate 170 is in the unfolded state, the central angle θ of the fan shape can be 0° to 150°, for example, the central angle θ can be 0°, 90°, 150°, etc. In this way, not only is the effect of the first smoke-collecting plate 170 in preventing oil fumes from escaping to the side guaranteed, but it is also easy to store the first smoke-collecting plate 170, saving space.

[0055] See also Figure 2 , Figure 3 and Figure 14 The left and right sides of the second smoke guide plate 140 can be respectively connected to the second smoke gathering plate 180. For example... Figure 9 With the smoke inlet 111 open, the second smoke-collecting plate 180 can be located outside the smoke collection chamber 112. For example... Figure 8 With the smoke inlet 111 closed, the second smoke-collecting plate 180 can be located at least partially within the smoke collection chamber 112. On the one hand, this further enhances the effect of preventing oil fumes from escaping to the side and further improves the smoke collection efficiency of the smoke collection assembly 10; on the other hand, it facilitates the storage of the second smoke-collecting plate 180, thereby effectively saving space.

[0056] In some embodiments, the second smoke-gathering plate 180 can be made of a rigid material, which facilitates the connection between the second smoke-gathering plate 180 and the second smoke-guiding plate 140, and provides a good smoke-gathering effect. Of course, the second smoke-gathering plate 180 can also be made of other materials, which are not specifically limited here, as long as the smoke-gathering effect of the second smoke-gathering plate 180 is guaranteed.

[0057] See Figure 3 Along the length of the front side plate 113, there can be a gap L between the end of the first smoke-gathering plate 170 and the end of the second smoke-gathering plate 180. The gap L can be 2mm to 5mm, for example, 2mm, 3.5mm, 5mm, etc. In this way, when the gap L is within this range, interference between the first smoke-gathering plate 170 and the second smoke-gathering plate 180 during movement is avoided, and the smoke-gathering effect of the first smoke-gathering plate 170 and the second smoke-gathering plate 180 is guaranteed.

[0058] See also Figure 2 , Figure 9 and Figure 14 The second smoke-gathering plate 180 can be fan-shaped. In this case, the radius of the fan shape of the second smoke-gathering plate 180 can be equal to the width of the second smoke guide plate 140. This improves the smoke-gathering effect of the second smoke-gathering plate 180.

[0059] See also Figure 2 , Figure 3 and Figure 8 A first hole 1131 may be provided on the front side plate 113. When the smoke inlet 111 is closed, at least a portion of the second smoke-collecting plate 180 can pass through the first hole 1131 and be located within the smoke collection chamber 112. Understandably, since the second smoke-collecting plate 180 is located on the left and right sides of the second smoke guide plate 140, the first hole 1131 can be correspondingly located on the left and right sides of the front side plate 113. The shape of the first hole 1131 may be similar to the side view shape of the second smoke-collecting plate 180 (i.e., it may refer to the side of the second smoke-collecting plate 180 opposite to the first hole 1131) so that the second smoke-collecting plate 180 can smoothly pass through the first hole 1131. In this way, it is not only convenient to store the second smoke-collecting plate 180 and avoid interference between the second smoke-collecting plate 180 and the front side plate 113, but also saves space.

[0060] See also Figures 8 to 10The first drive assembly 130 may include a first drive member 131, a first connecting rod 132, and a second connecting rod 133. The first drive member 131 may be a geared motor or a stepper motor, etc. Both the first drive member 131 and the first connecting rod 132 may be disposed within the smoke collection chamber 112. The second connecting rod 133 may be connected to the first smoke guide plate 120. The second connecting rod 133 may be connected to the first smoke guide plate 120 by means of screws or adhesive. The first connecting rod 132 may be connected between the first drive member 131 and the second connecting rod 133, and the first connecting rod 132 may be hinged to the second connecting rod 133. Specifically, the first connecting rod 132 and the second connecting rod 133 may be connected by a pin to achieve relative rotation between them. On the one hand, the first driving component 131 and the first connecting rod 132 are both located inside the smoke collection chamber 112, which reduces the space occupied by the first driving component 130 outside the cover 110 and avoids interference with the rotation of the first smoke guide plate 120. On the other hand, the first connecting rod 132 is hinged to the second connecting rod 133, which further improves the angular flexibility of the first smoke guide plate 120 relative to the front side plate 113, ensuring that the first smoke guide plate 120 can flexibly adjust its angle according to the oil fume concentration.

[0061] In some embodiments, the first driving member 131 may be covered by a first oil-proof cover 134, and the first driving member 131 can be fixed to the front side plate 113 by the first oil-proof cover 134. Specifically, the first oil-proof cover 134 and the front side plate 113 can be connected by fasteners such as screws or bolts, so that the first driving member 131 can be stably fixed between the first oil-proof cover 134 and the front side plate 113. The first oil-proof cover 134 can also be connected to the front side plate 113 by means of adhesive or snap-fit ​​connection. In this way, not only is the complex processing required to directly fix the first driving member 131 to the front side plate 113 avoided, but the first oil-proof cover 134 also effectively blocks the erosion or contamination of the first driving member 131 by oil, thereby extending the service life of the first driving member 131. Of course, the first driving member 131 can also be fixed to the left side plate or the right side plate, etc., without specific limitation, as long as the first driving assembly 130 can drive the first smoke guide plate 120 to rotate.

[0062] See Figure 10 The first link 132 can be constructed in an arc shape. Specifically, the first link 132 can be constructed in a circular arc shape. This provides a more uniform stress distribution, higher motion accuracy, and thus better drives the second link 133. Of course, the first link 132 can also be constructed in other shapes, such as an arc shape or a hook shape, etc.

[0063] See also Figure 2 and Figure 3 A second hole 1132 can be provided on the front side panel 113. For example... Figure 9With the smoke inlet 111 open, a portion of the second connecting rod 133 can extend out of the smoke collection chamber 112 through the second hole 1132. Understandably, the shape of the second hole 1132 can be similar to the side view of the second connecting rod 133 (i.e., it can refer to the side of the second connecting rod 133 opposite to the second hole 1132) to facilitate the smooth passage of the second connecting rod 133 through the second hole 1132. Figure 8 With the smoke inlet 111 closed, the first drive assembly 130 can be located within the smoke collection chamber 112. This avoids interference between the second link 133 and the front side plate 113 when the second link 133 drives the first smoke guide plate 120 to move.

[0064] See also Figures 8 to 10 The second link 133 may have a first segment 1331 and a second segment 1332. The first segment 1331 may be hinged to the first link 132. The second segment 1332 may be connected to the first smoke guide plate 120, and the first segment 1331 may be inclined relative to the second segment 1332. In this way, the second link 133 can better bear the force to push and pull the first smoke guide plate 120, and also avoids interference between the second link 133 and the front side plate 113 during movement.

[0065] In some embodiments, the first segment 1331 and the second segment 1332 can be connected by an arc segment to provide a more uniform stress distribution, so that the second link 133 can be better stressed to push and pull the first smoke guide plate 120.

[0066] See also Figure 2 , Figure 3 and Figure 9 A third hole 1133 may be provided on the front side panel 113. When the smoke inlet 111 is closed, the second drive assembly 150 can pass through the third hole 1133 and be located inside the smoke collection chamber 112. That is, when the smoke inlet 111 is open, the second drive assembly 150 can pass through the third hole 1133 and be located outside the smoke collection chamber 112. In this way, interference between the second drive assembly 150 and the front side panel 113 is avoided, and space is also saved.

[0067] See also Figure 2 , Figure 3 and Figure 11The second drive assembly 150 may include a second drive member 151, a third link 152, and a fourth link 153. The second drive member 151 may be a geared motor or a stepper motor, etc. The second drive member 151 may be mounted on the first smoke guide plate 120. The fourth link 153 may be connected to the second smoke guide plate 140. The third link 152 may be connected between the second drive member 151 and the fourth link 153, and the third link 152 may be hinged to the fourth link 153. Specifically, the third link 152 and the fourth link 153 may be connected by a pin to achieve relative rotation between them. Thus, by mounting the second drive member 151 on the first smoke guide plate 120 and hinged the third link 152 and the fourth link 153, the angular flexibility of the second smoke guide plate 140 relative to the first smoke guide plate 120 is further improved, ensuring that the second smoke guide plate 140 can flexibly adjust its angle according to the concentration of oil fumes.

[0068] In some embodiments, the second driving member 151 may be covered by a second oil-proof cover 154, and the second driving member 151 can be fixed to the first smoke guide plate 120 by the second oil-proof cover 154. Specifically, the second oil-proof cover 154 and the first smoke guide plate 120 can be connected by fasteners such as screws or bolts, so that the second driving member 151 can be stably fixed between the second oil-proof cover 154 and the first smoke guide plate 120. The second oil-proof cover 154 can also be connected to the first smoke guide plate 120 by means of adhesive or snap-fit ​​connection. In this way, not only is the complex processing required to directly fix the first driving member 131 to the first smoke guide plate 120 avoided, but the second oil-proof cover 154 also effectively blocks the erosion or contamination of the second driving member 151 by oil, thereby extending the service life of the second driving member 151.

[0069] See Figure 3 Along the length of the first smoke guide plate 120, the second drive assembly 150 is positioned closer to the center of the first smoke guide plate 120 than the first drive assembly 130. In other words, the first drive assembly 130 is positioned closer to the side of the first smoke guide plate 120 than the second drive assembly 150. Understandably, the second drive assembly 150 is lighter overall, avoiding significant resistance to the rotation of the first smoke guide plate 120. Thus, the second drive assembly 150's central placement helps maintain a uniform and stable thrust, improving the rotational efficiency of the second smoke guide plate 140 relative to the first smoke guide plate 120. Because the first drive assembly 130 is positioned close to the side of the first smoke guide plate 120, the second hole 1132 can be correspondingly positioned on the side of the front side plate 113 to allow the second connecting rod 133 to pass through. Because the second drive assembly 150 is positioned close to the center of the first smoke guide plate 120, the third hole 1133 can be correspondingly positioned in the center of the front side plate 113 to allow the second drive assembly 150 to pass through.

[0070] In some embodiments, the number of smoke inlets 111 can be two, the two smoke inlets 111 can be spaced apart, and the third hole 1133 can be disposed between the two smoke inlets 111, thereby facilitating the insertion of the second drive assembly 150.

[0071] See Figure 9 The first smoke guide plate 120 can have a rotation angle α relative to the cover 110. The rotation angle α can be 0° to 150°, for example, 0°, 90°, 150°, etc. It should be noted that the maximum rotation angle of the first smoke guide plate 120 relative to the cover 110 can be 150°. In this way, when the rotation angle α is within this range, the oil fumes can be fully guided to the smoke inlet 111, ensuring the smoke guiding effect. Since the first smoke gathering plate 170 is connected to the front side plate 113 and the first smoke guide plate 120 respectively, when the first smoke gathering plate 170 is fan-shaped, its maximum central angle after unfolding is the same as the maximum rotation angle of the first smoke guide plate 120. This ensures that the maximum rotation angle of the first smoke guide plate 120 will not exceed the maximum central angle of the first smoke gathering plate 170, avoiding the first smoke gathering plate 170 from obstructing the rotation of the first smoke guide plate 120 relative to the front side plate 113, and preventing damage to the first smoke gathering plate 170 due to angle mismatch.

[0072] See also Figure 4 and Figure 5 The second smoke guide plate 140 can have a rotation angle β relative to the vertical line P-P' perpendicular to the first smoke guide plate 120. The rotation angle β can be 0° to 180°, for example, 0°, 90°, 180°, etc. In this way, when the rotation angle β is within this range, it avoids obstructing the user's view during cooking and can effectively guide the oil fumes to the smoke inlet 111.

[0073] See also Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 11The first smoke guide plate 120 may have a first side 121. When the smoke inlet 111 is open, the first side 121 may be separated from the hood 110, and the second smoke guide plate 140 may have a second side 141 opposite to the first side 121. A gap 191 will be generated between the first side 121 and the second side 141 during the rotation of the second smoke guide plate 140 relative to the first smoke guide plate 120. The size S of the gap 191 can be 5mm to 10mm, for example, 5mm, 7mm, 10mm, etc. The second side 141 and the first side 121 can be connected by a flexible member 192. Thus, by filling the gap 191 generated during the rotation between the first smoke guide plate 120 and the second smoke guide plate 140 by the flexible member 192, oil fumes escape is prevented, further improving the smoke guiding effect. Specifically, the flexible member 192 can be made of soft rubber material, with one end fixed to the first side 121 and the other end fixed to the second side 141. The overall structure of the flexible component 192 can be a fan-shaped layered distribution, which can automatically adapt to the opening and closing angles of the first smoke guide plate 120 and the second smoke guide plate 140 to fill the flip gap 191 and prevent oil fumes from escaping. In an embodiment not shown in the figure, explosion-proof films can be attached to the first smoke guide plate 120 and the second smoke guide plate 140 to prevent oil fumes from escaping from the gap 191.

[0074] See also Figures 1 to 14 With the smoke inlet 111 open, the first driving member 131 drives the first connecting rod 132 to rotate, which in turn drives the second connecting rod 133 to rotate, causing the first smoke guide plate 120 to open at a certain angle. Simultaneously, the first smoke gathering plate 170, fixed between the first smoke guide plate 120 and the front side plate 113, can unfold into a fan shape at a certain angle. The second smoke guide plate 140 will form a certain angle relative to the front side plate 113 along with the first smoke guide plate 120. The second smoke gathering plate 180, fixed to the second smoke guide plate 140, can move outward from the smoke collection chamber 112 through the first hole 1131. Then, the second driving member 151 drives the third connecting rod 152 to rotate, which in turn drives the fourth connecting rod 153 to rotate, allowing the second smoke guide plate 140 to rotate at a certain angle relative to the first smoke guide plate 120, and the second smoke gathering plate 180 to be completely placed outside the smoke collection chamber 112. This not only improves the smoke collection effect of the smoke collection assembly 10 but also prevents oil fumes from escaping from both sides.

[0075] See Figure 15 According to another aspect of the present invention, a range hood 1 is provided. The range hood 1 may include a housing 20. A smoke collection assembly 10 as described above may be connected to the lower part of the housing 20. The range hood 1 of the present invention includes the smoke collection assembly 10 as described above. Since the smoke collection assembly 10 has the aforementioned beneficial effects, the range hood 1 including the smoke collection assembly 10 as described above will necessarily also have the aforementioned beneficial effects.
