Description

TECHNICAL FIELD

[0001] The utility model relates to range hood technical field, specifically, a smoke collecting assembly and range hood. BACKGROUND

[0002] The existing range hood includes a smoke collecting assembly, which mostly has a smoke collecting cavity and a front side plate. The front side plate is provided with a smoke inlet, and a smoke guide plate is connected to the front side plate. The smoke guide plate is designed as a whole plate body that can open or close the smoke inlet. When the smoke guide plate closes the smoke inlet, it blocks the oil fume from entering the smoke collecting assembly. When the smoke guide plate opens the smoke inlet, it can guide the oil fume into the smoke collecting cavity, so that the range hood can smoke.

[0003] However, when the smoke guide plate opens the smoke inlet, the whole plate body rotates relative to the smoke inlet, and the rotation angle is fixed, so that the smoke guide plate cannot adjustably guide the smoke, and it is easy to block the user's line of sight during cooking, increasing the possibility of collision between the user and the smoke guide plate during cooking, and causing safety risks. SUMMARY

[0004] In order to at least partially solve the problems existing in the prior art, according to one aspect of the utility model, a smoke collecting assembly is provided, and the technical scheme is as follows.

[0005] The smoke collecting assembly includes a cover body, a first smoke guide plate, a first drive assembly, a second smoke guide plate, and a second drive assembly. The cover body encloses a smoke collecting cavity with a smoke inlet. The first smoke guide plate is rotationally connected to the cover body. The first drive assembly is at least partially arranged in the smoke collecting cavity, and the first drive assembly is connected to the first smoke guide plate and drives the first smoke guide plate to rotate relative to the cover body to open or close at least part of the smoke inlet. The second smoke guide plate is rotationally connected to the first smoke guide plate. The second drive assembly is at least partially arranged in the smoke collecting cavity, and the second drive assembly is connected to the second smoke guide plate and drives the second smoke guide plate to rotate relative to the first smoke guide plate to open or close another part of the smoke inlet.

[0006] The smoke collecting assembly of the utility model has the following advantages. On the one hand, the first smoke guide plate and the second smoke guide plate are controlled by separate drive assemblies, and the two smoke guide plates can freely flip, so that the flip angle can be adjusted according to the oil fume concentration to combine different smoke guide angles, smoke guide sizes, and smoke guide distances, thereby fully guiding the oil fume to flow to the smoke inlet, enhancing the smoke guide effect, avoiding blocking the user's line of sight during cooking, reducing the risk of collision between the user and the smoke guide plate, and improving the use safety. On the other hand, both drive assemblies are arranged in the smoke collecting cavity, thereby effectively saving space.

[0007] Exemplarily, the cover body has a front side plate, and the smoke inlet is arranged on the front side plate; the first driving assembly has a first driving member, and the second driving assembly has a second driving member; the first driving member and the second driving member are arranged in the smoke collecting cavity through the front side plate, and the first driving member and the second driving member are spaced apart through the smoke inlet. In this way, both the driving members are arranged in the smoke collecting cavity, effectively saving space, and the two driving members are spaced apart through the smoke inlet, avoiding interference between the two driving assemblies during movement.

[0008] Exemplarily, the first driving member is connected with the first smoke guide plate through a first connecting rod assembly, and the first connecting rod assembly at least partially extends outside the smoke collecting cavity in the case of opening the smoke inlet. In this way, the first driving member drives the first connecting rod assembly to drive the first smoke guide plate to freely flip.

[0009] Exemplarily, the first connecting rod assembly has a first connecting rod and a second connecting rod, the second connecting rod is connected with the first smoke guide plate, the first connecting rod is connected between the first driving member and the second connecting rod, and the first connecting rod is hinged with the second connecting rod. In this way, by hinging the first connecting rod with the second connecting rod, the angular flexibility of the first smoke guide plate relative to the front side plate is further improved, ensuring that the first smoke guide plate can flexibly adjust the angle according to the oil fume concentration.

[0010] Exemplarily, the first connecting rod is configured in an arc shape. In this way, more uniform stress distribution can be provided, with higher movement precision, thereby better driving the second connecting rod to move.

[0011] Exemplarily, the front side plate is provided with a first hole, and a part of the second connecting rod extends outside the smoke collecting cavity through the first hole in the case of opening the smoke inlet. In this way, interference between the second connecting rod and the front side plate during movement of the second connecting rod driving the first smoke guide plate is avoided.

[0012] Exemplarily, the second connecting rod has a first segment and a second segment, the first segment is hinged with the first connecting rod, the second segment is connected with the first smoke guide plate, and the first segment is arranged obliquely relative to the second segment. In this way, the second connecting rod can better bear force to push and pull the first smoke guide plate, and interference between the second connecting rod and the front side plate during movement is also avoided.

[0013] Exemplarily, the second driving member is connected with the second smoke guide plate through a second connecting rod assembly, and the second connecting rod assembly at least partially extends outside the smoke collecting cavity in the case of opening the smoke inlet. In this way, the second driving member drives the second connecting rod assembly to drive the second smoke guide plate to freely flip.

[0014] For example, when the smoke inlet is open, the length of the first connecting rod assembly extending outside the smoke collection chamber is less than the length of the second connecting rod assembly extending outside the smoke collection chamber. This configuration, when the smoke inlet is open, makes the distance between the second smoke guide plate and the front side plate greater than the distance between the first smoke guide plate and the front side plate, thereby improving the smoke guiding effect.

[0015] For example, the second linkage assembly has a third linkage and a fourth linkage. The fourth linkage is connected to the second smoke guide plate, and the third linkage is connected between the second drive member and the fourth linkage, and the third linkage and the fourth linkage are hinged together. This arrangement, by hinged between the third linkage and the fourth linkage, 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.

[0016] For example, a second hole is provided on the front side plate, and when the smoke inlet is open, a portion of the third link extends out of the smoke collection chamber through the second hole. This arrangement avoids interference between the third link and the front side plate when the third link drives the first smoke guide plate to move.

[0017] 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.

[0018] 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.

[0019] 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.

[0020] 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.

[0021] For example, the second smoke-gathering plate is fan-shaped. This configuration improves the smoke-gathering effect of the second smoke-gathering plate.

[0022] For example, a third 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 third 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.

[0023] 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.

[0024] 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.

[0025] 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.

[0026] 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.

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.

Detailed Implementation

[0048] 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.

[0049] 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.

[0050] 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.

[0051] See also Figures 1 to 4The 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 can enclose a smoke collection cavity 112 having a smoke inlet 111. The first smoke guide plate 120 can be rotatably connected to the cover 110. The first drive assembly 130 can be at least partially disposed within the smoke collection cavity 112, and the first drive assembly 130 can 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 at least a portion of the smoke inlet 111. The second smoke guide plate 140 can be rotatably connected to the first smoke guide plate 120. The second drive assembly 150 can be at least partially disposed within the smoke collection cavity 112, and the second drive assembly 150 can 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 to open or close another portion of the smoke inlet 111.

[0052] The smoke collection assembly 10 of this utility model has two advantages. 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 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, both drive components are set in the smoke collection chamber 112, thereby effectively saving space.

[0053] 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.

[0054] 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.

[0055] See also Figure 3 and Figure 4The 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 can be one or more, without specific limitation, as long as the smoke collection function of the smoke collection assembly 10 is guaranteed. The first drive assembly 130 may have a first drive member 131. The first drive member 131 may be a geared motor or a stepping motor, etc. The second drive assembly 150 may have a second drive member 151. The second drive member 151 may be a geared motor or a stepping motor, etc. Both the first drive member 131 and the second drive member 151 can be located within the smoke collection chamber 112 through the front side plate 113, and the first drive member 131 and the second drive member 151 can be separated by the smoke inlet 111. In this way, both drive members are located within the smoke collection chamber 112, effectively saving space, and the separation of the two drive members by the smoke inlet 111 avoids interference between the two drive assemblies during movement.

[0056] 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.

[0057] 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.

[0058] See Figure 7 The first driving member 131 can be connected to the first smoke guide plate 120 via the first connecting rod assembly 132. When the smoke inlet 111 is open, the first connecting rod assembly 132 can at least partially extend outside the smoke collection chamber 112. In this way, the first driving member 131 drives the first connecting rod assembly 132 to freely rotate the first smoke guide plate 120.

[0059] See also Figure 4 , Figure 5 and Figure 7The first linkage assembly 132 may have a first linkage 1321 and a second linkage 1322. The second linkage 1322 may be connected to the first smoke guide plate 120. The second linkage 1322 may be connected to the first smoke guide plate 120 by means of screws or adhesive. The first linkage 1321 may be connected between the first driving member 131 and the second linkage 1322, and the first linkage 1321 may be hinged to the second linkage 1322. Specifically, the first linkage 1321 and the second linkage 1322 may be connected by a pin to achieve relative rotation between the two. In this way, by hinged to the first linkage 1321 and the second linkage 1322, the angular flexibility of the first smoke guide plate 120 relative to the front side plate 113 is further improved, ensuring that the first smoke guide plate 120 can flexibly adjust its angle according to the concentration of oil fumes.

[0060] See Figure 5 The first link 1321 can be constructed in an arc shape. Specifically, the first link 1321 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 1322. Of course, the first link 1321 can also be constructed in other shapes, such as an arc shape or a hook shape, etc.

[0061] See also Figure 3 , Figure 5 and Figure 7 A first hole 1131 may be provided on the front side plate 113. When the smoke inlet 111 is open, a portion of the second connecting rod 1322 can extend out of the smoke collection chamber 112 through the first hole 1131. Understandably, the shape of the first hole 1131 can be similar to the side view shape of the second connecting rod 1322 (i.e., the side of the second connecting rod 1322 opposite to the first hole 1131) so that the second connecting rod 1322 can pass smoothly through the first hole 1131. For example, the shape of the first hole 1131 can be an elongated waist-shaped through hole, etc. When the smoke inlet 111 is closed, the first drive assembly 130 can be located inside the smoke collection chamber 112. In this way, interference between the second connecting rod 1322 and the front side plate 113 is avoided when the second connecting rod 1322 drives the first smoke guide plate 120 to move.

[0062] See also Figure 5 and Figure 7The second link 1322 may have a first segment 1322a and a second segment 1322b. The first segment 1322a may be hinged to the first link 1321. The second segment 1322b may be connected to the first smoke guide plate 120, and the first segment 1322a may be inclined relative to the second segment 1322b. This allows the second link 1322 to better bear the force to push and pull the first smoke guide plate 120, and also avoids interference between the second link 1322 and the front side plate 113 during movement. In some embodiments, the first segment 1322a and the second segment 1322b may be connected by an arc-shaped segment to provide a more uniform stress distribution, allowing the second link 1322 to better bear the force to push and pull the first smoke guide plate 120.

[0063] In some embodiments, the first driving member 131 may be covered by a first oil-proof cover 133, and the first driving member 131 can be fixed to the front side plate 113 by the first oil-proof cover 133. Specifically, the first oil-proof cover 133 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 133 and the front side plate 113. The first oil-proof cover 133 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 133 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.

[0064] See also Figure 4 and Figure 7 The second driving member 151 can be connected to the second smoke guide plate 140 via the second connecting rod assembly 152. When the smoke inlet 111 is open, the second connecting rod assembly 152 can at least partially extend outside the smoke collection chamber 112. In this way, the second driving member 151 drives the second connecting rod assembly 152 to freely rotate the second smoke guide plate 140.

[0065] See also Figure 7 , Figure 14 and Figure 15When the smoke inlet 111 is open, the length of the first connecting rod assembly 132 extending outside the smoke collection chamber 112 can be less than the length of the second connecting rod assembly 152 extending outside the smoke collection chamber 112. Thus, when the smoke inlet 111 is open, the distance between the second smoke guide plate 140 and the front side plate 113 is greater than the distance between the first smoke guide plate 120 and the front side plate 113, thereby improving the smoke guiding effect. It should be noted that when the first smoke guide plate 120 rotates relative to the front side plate 113 by a certain angle, the second smoke guide plate 140 follows the first smoke guide plate 120 and rotates relative to the front side plate 113 to the same angle. Then, depending on the concentration of oil fumes or the usage environment, the second smoke guide plate 140 rotates relative to the first smoke guide plate 120 to a suitable angle. Therefore, when the smoke inlet 111 is open, the distance between the second smoke guide plate 140 and the front side plate 113 is greater than the distance between the first smoke guide plate 120 and the front side plate 113.

[0066] See also Figure 4 , Figure 6 and Figure 7 The second linkage assembly 152 may have a third linkage 1521 and a fourth linkage 1522. The fourth linkage 1522 may be connected to the second smoke guide plate 140. The third linkage 1521 may be connected between the second drive member 151 and the fourth linkage 1522, and the third linkage 1521 may be hinged to the fourth linkage 1522. Specifically, the third linkage 1521 and the fourth linkage 1522 may be connected by a pin to achieve relative rotation between them. In this way, by hinged between the third linkage 1521 and the fourth linkage 1522, 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.

[0067] In some embodiments, the third link 1521 can be configured in an arc shape. Specifically, the third link 1521 can be configured in a circular arc shape. This can provide a more uniform stress distribution, resulting in higher motion accuracy and thus better driving the fourth link 1522. Of course, the third link 1521 can also be configured in other shapes, such as an arc shape or a hook shape, etc.

[0068] In some embodiments, the fourth link 1522 may have a third segment 1522a and a fourth segment 1522b. The third segment 1522a may be hinged to the third link 1521. The fourth segment 1522b may be connected to the second smoke guide plate 140, and the third segment 1522a may be inclined relative to the fourth segment 1522b. This allows the fourth link 1522 to better bear force to push and pull the second smoke guide plate 140, and also avoids interference between the fourth link 1522 and the front side plate 113 during movement.

[0069] In some embodiments, the third segment 1522a and the fourth segment 1522b can be connected by an arc segment to provide a more uniform stress distribution, so that the fourth link 1522 can be better stressed to push and pull the second smoke guide plate 140.

[0070] See also Figure 2 , Figure 3 , Figure 6 and Figure 7 A second hole 1132 may be provided on the front side plate 113. When the smoke inlet 111 is open, a portion of the third connecting rod 1521 can extend out of the smoke collection chamber 112 through the second hole 1132. Understandably, the shape of the second hole 1132 may be similar to the side view shape of the second connecting rod assembly 152 (i.e., it may refer to the side of the second connecting rod assembly 152 opposite to the second hole 1132) so that a portion of the third connecting rod 1521 can smoothly pass through the second hole 1132. For example, the second hole 1132 may be an elongated through hole, etc. When the smoke inlet 111 is closed, the second drive assembly 150 may be located inside the smoke collection chamber 112. It should be noted that since the first drive member 131 and the second drive member 151 are spaced apart through the smoke inlet 111, the first hole 1131 and the second hole 1132 are also spaced apart through the smoke inlet 111. This avoids interference between the third link 1521 and the front side plate 113 when the third link 1521 drives the first smoke guide plate 120 to move.

[0071] In some embodiments, the second driving member 151 may be covered by a second oil-proof cover 153, and the second driving member 151 can be fixed to the first smoke guide plate 120 by the second oil-proof cover 153. Specifically, the second oil-proof cover 153 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 153 and the first smoke guide plate 120. The second oil-proof cover 153 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 153 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.

[0072] See also Figure 2 , Figure 3 , Figure 4 and Figure 7 The cover 110 may have a front side plate 113. The smoke inlet 111 may be provided on the front side plate 113. First smoke gathering plates 170 may be provided on the left and right sides of the front side plate 113 respectively. In this way, the smoke gathering plates provided on both sides of the smoke inlet 111 not only prevent the oil fumes from escaping to the side, but also improve the smoke collection efficiency of the smoke collection assembly 10.

[0073] See also Figure 2 , Figure 4 , Figure 11 and Figure 12 The first smoke-gathering plate 170 is connected between the front side plate 113 and the first smoke guide plate 120 to form a foldable structure. When the smoke inlet 111 is open, the first smoke-gathering plate 170 can be in an unfolded state. 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 component, to achieve folding or unfolding. In embodiments not shown in the figures, the first smoke-gathering plate 170 can also be formed by multiple movable plates folding together, or multiple plates can be folded or unfolded via sliding members, etc. No specific limitations are made here, as long as the first smoke-gathering plate 170 can be folded or unfolded and its smoke-gathering effect is guaranteed. Furthermore, when the first smoke-gathering plate 170 is in the unfolded state, it can be fan-shaped, improving its smoke-gathering effect. At this time, the radius of the sector of the first smoke-collecting plate 170 can be equal to the width of the first smoke-guiding plate 120. The central angle θ of the sector when the first smoke-collecting plate 170 is in its unfolded state can be 0° to 150°, for example, 0°, 90°, 150°, etc. This not only ensures the effectiveness of the first smoke-collecting plate 170 in preventing fumes from escaping to the side, but also facilitates the storage of the first smoke-collecting plate 170, saving space.

[0074] See also Figure 2 , Figure 4 , Figure 7 and Figure 13 The left and right sides of the second smoke guide plate 140 can be respectively connected to second smoke collecting plates 180. When the smoke inlet 111 is open, the second smoke collecting plates 180 can be located outside the smoke collection chamber 112. When the smoke inlet 111 is closed, the second smoke collecting plates 180 can be located at least partially inside 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 plates 180, thereby effectively saving space.

[0075] 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.

[0076] See Figure 3Along 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.

[0077] See also Figure 7 and Figure 13 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.

[0078] See also Figures 2 to 4 A third hole 1133 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 third hole 1133 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 third hole 1133 can be correspondingly located on the left and right sides of the front side plate 113. The shape of the third hole 1133 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 third hole 1133) so that the second smoke-collecting plate 180 can smoothly pass through the third hole 1133. For example, the third hole 1133 may be an elongated through hole. 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.

[0079] See Figure 14 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°. With this setting, 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.

[0080] SeeFigure 15 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.

[0081] See also Figure 4 , Figure 7 , Figure 8 , Figure 9 and Figure 10 The 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 cover 110. The second smoke guide plate 140 may have a second side 141 opposite to the first side 121. During the rotation of the second smoke guide plate 140 relative to the first smoke guide plate 120, a gap 191 will be generated between the first side 121 and the second side 141. The size S of the gap 191 may be 5mm to 10mm, for example, the size S of the gap 191 may be 5mm, 7mm, 10mm, etc. The second side 141 and the first side 121 may be connected by a flexible member 192. In this way, by filling the gap 191 generated between the first smoke guide plate 120 and the second smoke guide plate 140 during rotation by the flexible member 192, the escape of oil fumes is prevented, and the smoke guiding effect is further improved. Specifically, the flexible member 192 may 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.

[0082] See also Figures 1 to 15With the smoke inlet 111 open, depending on the concentration of oil fumes, the first driving member 131 drives the first connecting rod 1321 to rotate, which in turn drives the second connecting rod 1322 to rotate. This causes 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 with the same angle as the first smoke guide plate 120. The second smoke guide plate 140, via the second driving assembly 150, forms the same angle relative to the front side plate 113 as the first smoke guide plate 120. Simultaneously, 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 third hole 1133. Then, depending on the change in oil fume concentration, the second driving member 151 drives the third connecting rod 1521 to rotate, which in turn drives the fourth connecting rod 1522 to rotate. This allows 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 can be completely placed outside the smoke collection chamber 112. In this way, not only is the smoke collection effect of the smoke collection component 10 improved, but the oil fumes are also prevented from escaping from both sides.

[0083] See Figure 16 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.
