Description

Technical Field

[0001] The utility model relates to the technical field of household appliances, in particular to an oil fume treatment device. Background Art

[0002] The existing range hoods include a smoke collecting cavity mechanism, a smoke baffle and an oil cup. Among them, the smoke collecting cavity mechanism is provided with a smoke inlet. The smoke baffle can be switched between a position where the smoke inlet is opened and a position where the smoke inlet is blocked. The oil cup is arranged below the smoke collecting cavity mechanism. Since there will be accumulated oil on the back side of the smoke baffle, a part of the accumulated oil will flow to the oil cup along a certain direction, and another part of the accumulated oil will flow to the outside of the range hood or the stove top from different positions around the smoke baffle, affecting the cleanliness of the range hood and the kitchen environment. In addition, when the existing range hood is in the shutdown state, the oil fume or accumulated oil inside the range hood will diffuse from the inside of the range hood to the environment, resulting in poor cleanliness of the range hood and the kitchen environment.

[0054] Embodiment 1

[0055] As Figures 1 to 4 shown, this embodiment provides an oil fume treatment device 100, which can be an oil fume extractor, an integrated stove, etc. This embodiment takes the oil fume extractor as an example for illustration. The oil fume extractor includes a main cabinet 60 and a smoke collecting cavity mechanism 20. The smoke collecting cavity mechanism 20 is arranged at the lower end of the main cabinet 60 and is connected to the inside of the main cabinet 60. As Figure 1 and Figure 2As shown in the figure, the smoke collecting cavity mechanism 20 includes a smoke collecting hood 21. The smoke collecting hood 21 includes a bottom plate 211, a front side plate assembly 212, a rear side plate assembly 213, a left side plate 214, a right side plate 215, and an upper end plate 216. The front side plate assembly 212, the left side plate 214, the rear side plate assembly 213, and the right side plate 215 are connected in sequence. The front side plate assembly 212 and the rear side plate assembly 213 are arranged at intervals in the front-rear direction, and the left side plate 214 and the right side plate 215 are arranged in the left-right direction. The front side plate assembly 212, the left side plate 214, the rear side plate assembly 213, and the right side plate 215 together form a cavity space. The cavity space includes an upper opening and a lower opening. The upper end plate 216 is located at the upper opening, and the bottom plate 211 is located at the lower opening.

[0056] In an alternative embodiment, as Figure 2 shown, the smoke collecting cavity mechanism 20 further includes a support frame 22. The support frame 22 is disposed inside the smoke collecting hood 21 and fixedly connected to the smoke collecting hood 21. By providing the support frame 22, the strength and hardness of the smoke collecting cavity mechanism 20 can be effectively improved. As Figure 2 shown, the support frame 22 includes one, two, or more support frames 22. One end of the support frame 22 is fixedly connected to the front side plate assembly 212, and the other end of the support frame 22 is fixedly connected to the rear side plate assembly 213. By providing a plurality of support frames 22, on the premise of saving space, the strength and hardness of the smoke collecting cavity mechanism 20 can be significantly improved. In addition, the structure of the support frame 22 is simple, which is convenient to achieve a quick and stable connection effect between the support frame 22 and the smoke collecting cavity mechanism 20. It should be noted that the support frame 22 can be fixedly connected to at least one of the front side plate assembly 212, the rear side plate assembly 213, the upper end plate 216, and the bottom plate 211, and can also significantly improve the strength and hardness of the smoke collecting cavity mechanism 20.

[0057] As Figures 2 to 4 shown, the range hood further includes a mounting mechanism 80. The mounting mechanism 80 is fixedly connected to the smoke collecting cavity mechanism 20. The driving device 10 is disposed in the mounting mechanism 80. On the one hand, the mounting mechanism 80 can be preferably connected to the smoke collecting cavity mechanism 20. On the other hand, the mounting mechanism 80 can also preferably support the driving device 10. By providing the mounting mechanism 80, it is convenient for the driving device 10 to be preferably installed and connected to the smoke collecting cavity mechanism 20.

[0058] In an alternative embodiment, as Figure 3As shown, the front side plate assembly 212 includes a front side plate 2121 and a first reinforcing member 2122. Among them, the front side plate 2121, the left side plate 214, the rear side plate assembly 213, and the right side plate 215 are fixedly connected in sequence. The first reinforcing member 2122 is disposed inside the front side plate 2121. By providing the first reinforcing member 2122, the strength and hardness of the front side plate assembly 212 are improved to achieve stable support for the support frame 22, the installation mechanism 80, the main chassis 60, and the driving device 10.

[0059] In an alternative embodiment, as Figure 2 、 Figure 4 and Figure 9 shown, the rear side plate assembly 213 includes a rear side plate 2131 and a second reinforcing member 2132 disposed thereon. The support frame 22 is fixedly connected to the second reinforcing member 2132. By providing the second reinforcing member 2132, the strength and hardness of the rear side plate assembly 213 are improved to achieve stable support for the support frame 22, the installation mechanism 80, the main chassis 60, and the driving device 10.

[0060] In an alternative embodiment, the bottom plate 211, the left side plate 214, the right side plate 215, the upper end plate 216, etc. can also adopt a similar structure to the aforementioned front side plate assembly 212 or rear side plate assembly 213, and can also achieve the effect of further strengthening the stable support of the smoke collecting chamber mechanism 20 for the driving device 10 and the main chassis 60.

[0061] As Figure 1 and Figure 2 shown, the bottom plate 211 is provided with a first concave cavity 2111 and a second concave cavity 2112. The first concave cavity 2111 and the second concave cavity 2112 are arranged in the left-right direction. A first smoke inlet 21111 is formed in the bottom wall of the first concave cavity 2111, and a second smoke inlet 21121 is formed in the bottom wall of the second concave cavity 2112. When the main chassis 60 is operating, the fan inside the main chassis 60 rotates to form a negative pressure area, and the oil fume outside the range hood can enter the main chassis 60 after passing through the two concave cavities and the two smoke inlets in sequence. The oil fume is filtered inside the main chassis 60 and then discharged to the outside of the main chassis 60.

[0062] In an alternative embodiment, it can also be that only one first concave cavity 2111 is formed on the bottom plate 211. In an alternative embodiment, three, four or more smoke inlets can also be formed on the bottom plate 211.

[0063] As Figure 1 and Figure 2As shown, the range hood further includes a smoke baffle assembly, and the smoke baffle assembly includes a first smoke baffle 30 and a second smoke baffle 40. Among them, the first smoke baffle 30 corresponds to the first smoke inlet 21111, and the second smoke baffle 40 corresponds to the second smoke inlet 21121. The first smoke baffle 30 can selectively switch between a first position where the first smoke inlet 21111 is opened and a second position where the first smoke inlet 21111 is blocked. The second smoke baffle 40 switches between a third position where the second smoke inlet 21121 is opened and a fourth position where the second smoke inlet 21121 is blocked. The open or blocked states of the first smoke inlet 21111 and the second smoke inlet 21121 can be adaptively adjusted according to the specific situation of the cooking fumes.

[0064] In an optional embodiment, as Figure 1 shown, the range hood further includes an oil cup 70, and the oil cup 70 is arranged at the lower end of the smoke collecting cavity mechanism 20. The dirty oil inside the smoke collecting cavity mechanism 20 can flow into the oil cup 70 for storage.

[0065] As Figures 2 to 4 shown, the range hood further includes a driving device 10, and the driving device 10 is used to make the first smoke baffle 30 and the second smoke baffle 40 move synchronously, so that each smoke baffle switches between a position where the corresponding smoke inlet is blocked and a position where the corresponding smoke inlet is opened.

[0066] In the existing range hoods, since there will be accumulated oil on the back sides of the first smoke baffle 30 and the second smoke baffle 40, a part of the accumulated oil will flow to the oil cup 70 along a certain direction, and another part of the accumulated oil will flow to the outside of the range hood or the stove top from different positions around the first smoke baffle 30 and the second smoke baffle 40, affecting the cleanliness of the range hood and the kitchen environment.

[0067] To solve the above problems, as Figure 5 and Figure 6As shown, taking the structure of the first smoke baffle 30 as an example for illustration, the oil cup 70 has an upper opening 71. The first smoke baffle 30 is arranged above the upper opening 71. The first smoke baffle 30 includes a smoke baffle body 32 and a flange 34 provided on its peripheral side. An oil leakage port 35 is also provided on the first smoke baffle 30. The first smoke baffle 30 can be switched between a first position and a second position. When the first smoke baffle 30 is in the first position, the first smoke baffle 30 opens the smoke inlet. The upper opening 71 is disposed opposite to or communicated with the oil leakage port 35. Under the blocking action of the flange 34, the accumulated oil on the back of the first smoke baffle 30 can only enter the upper opening 71 through the oil leakage port 35, thereby avoiding the accumulated oil flowing from different positions around the first smoke baffle 30 to the outside of the range hood or the stove top, and ensuring better cleanliness of the range hood and the kitchen environment. When the first smoke baffle 30 is in the second position, the first smoke baffle 30 is in sealing contact with the smoke collecting cavity mechanism 20. The first smoke baffle 30 can completely block the smoke inlet. When the range hood is in the shutdown state, it can avoid the diffusion of the oil fume or accumulated oil inside the range hood to the environment, and ensure better cleanliness of the range hood and the kitchen environment.

[0068] It should be noted that the upper opening 71 and the oil leakage port 35 can be communicated through a conduit. It should be noted that the structure of the second smoke baffle 40 is substantially the same as that of the first smoke baffle 30.

[0069] As an optional embodiment, as Figure 5 and Figure 6 shown, the first smoke baffle 30 is inclined downward from front to back. The lowest position of the first smoke baffle 30 is provided with an oil leakage port 35, which can enable the accumulated oil on the back of the first smoke baffle 30 to converge well at the oil leakage port 35 and enable the accumulated oil to be discharged smoothly from the oil leakage port 35. It should be noted that the arrangement of the second smoke baffle 40 is substantially the same as that of the first smoke baffle 30.

[0070] As an optional embodiment, as Figure 5 and Figure 6 shown, the oil leakage port 35 is provided on the flange 34, which is convenient for the rapid processing and manufacturing of the oil leakage port 35. In other embodiments, the oil leakage port 35 can also be provided on the smoke baffle body 32. It can also be that a part of the oil leakage port 35 is provided on the smoke baffle body 32 and the other part of the oil leakage port 35 is provided on the flange 34.

[0071] As an optional embodiment, as Figure 5 and Figure 6As shown, the first smoke baffle 30 further includes a drainage portion 36. The drainage portion 36 has a first end and a second end. The first end is fixedly connected to the baffle body 32 or the flange 34, and the second end extends in the direction of the upward opening 71. The arrangement of the drainage portion 36 can better drain the accumulated oil at the oil leakage port 35 upward to the opening 71, facilitating the accumulated oil to better enter the interior of the oil cup 70.

[0072] As an alternative embodiment, as Figure 5 and Figure 6 shown, a ring-shaped protrusion 217 is provided on the smoke collecting cavity mechanism 20. The ring-shaped protrusion 217 surrounds the outer periphery of the first smoke inlet 21111. When the first smoke baffle 30 is in the second position, the ring-shaped protrusion 217 abuts against the first smoke baffle 30. When the first smoke baffle 30 seals the first smoke inlet 21111, the cooperation between the ring-shaped protrusion 217 and the first smoke baffle 30 can achieve a better sealing effect for the first smoke inlet 21111, preventing the oil fume or accumulated oil inside the range hood from diffusing from the inside of the range hood to the environment, ensuring a better cleanliness of the cooking appliance and a cleaner kitchen environment.

[0073] In an alternative embodiment, it can also be that a ring-shaped protrusion 217 is provided on the first smoke baffle 30. The ring-shaped protrusion 217 surrounds the outer periphery of the first smoke inlet 21111 and abuts against the smoke collecting cavity mechanism 20. When the first smoke baffle 30 seals the first smoke inlet 21111, the cooperation between the ring-shaped protrusion 217 and the smoke collecting cavity mechanism 20 can achieve a better sealing effect for the first smoke inlet 21111, preventing the oil fume or accumulated oil inside the range hood from diffusing from the inside of the range hood to the environment, ensuring a better cleanliness of the cooking appliance and a cleaner kitchen environment.

[0074] As an alternative embodiment, as Figure 7 shown, the smoke collecting cavity mechanism 20 includes a bottom plate 211 and a ring-shaped protrusion 217 provided thereon. The ring-shaped protrusion 217 abuts against the back side of the baffle body 32. The flange 34 is located on the back side of the baffle body 32. The first height H1 of the ring-shaped protrusion 217 and the bottom plate 211 in the thickness direction of the bottom plate 211 is greater than the second height H2 of the flange 34. Through the settings of the aforementioned first height H1 and second height H2, the contact between the baffle body 32 and the ring-shaped protrusion 217 can be made tight, so as to ensure that after the range hood is closed, the first smoke baffle 30 has a good sealing performance and prevent the check valve from smoking and smelling.

[0075] As an alternative embodiment, as Figure 8As shown, the smoke collecting cavity mechanism 20 includes a bottom plate 211 having a liquid leakage port 2113. The smoke inlet is formed in the bottom plate 211 and is located above the liquid leakage port 2113. The liquid leakage port 2113 is located above the upper opening 71. The accumulated oil in the smoke collecting cavity mechanism 20 can flow to the liquid leakage port 2113 and flow from the liquid leakage port 2113 into the oil cup 70, effectively reducing the accumulation of a large amount of oil inside the smoke collecting cavity mechanism 20.

[0076] As an alternative embodiment, as Figure 6 and Figure 7 shown, a ring-shaped oil guiding groove 2171 is provided on the back side of the bottom plate 211. The ring-shaped oil guiding groove 2171 surrounds the outer periphery of the smoke inlet. A diversion channel 2172 is provided at the lowest position of the ring-shaped oil guiding groove 2171. The accumulated oil in the oil guiding groove 2171 can flow to the liquid leakage port 2113 through the diversion channel 2172. The setting of the ring-shaped oil guiding groove 2171 can effectively guide the oil stain. Exemplarily, the shape of the oil guiding groove 2171 can be V-shaped, U-shaped or other shapes.

[0077] As an alternative embodiment, as Figure 1 shown, the first smoke baffle 30 and the second smoke baffle 40 are arranged in a V shape in the left-right direction. The oil leakage ports 35 of the first smoke baffle 30 and the second smoke baffle 40 are both located at the middle position of the oil cup 70 in the left-right direction, which can ensure that the accumulated oil leaked from the oil leakage ports 35 completely enters the oil cup 70 through the upper opening 71.

[0078] In the existing one, since the main chassis 60 includes an air duct, an impeller and a motor, the total weight of the main chassis 60 is relatively heavy, and there is a risk of vertical drop during the transportation of the main chassis 60. The existing main chassis 60 is arranged at the upper end of the smoke collecting cavity mechanism 20 and is fixedly connected to the upper end plate 216. The connection between the main chassis 60 and the smoke collecting cavity mechanism 20 is relatively weak. When the range hood is subjected to a vertical impact, the smoke collecting cavity mechanism 20 is easily deformed and damaged.

[0079] To solve the above problems, in combination with Figures 1 to 10 shown, the main chassis 60 with a relatively heavy total weight is fixedly connected to the smoke collecting hood 21, the support frame 22 and the mounting mechanism 80 respectively. Through the foregoing connection method, the weight of the main chassis 60 can be relatively dispersed to different positions of the smoke collecting hood 21, the support frame 22 and the mounting mechanism 80. A better dispersion effect can be obtained for the relatively large weight of the main chassis 60. Different positions of the smoke collecting hood 21, the support frame 22 and the mounting mechanism 80 can jointly provide a better supporting effect for the relatively heavy main chassis 60. Even if the range hood is subjected to a vertical impact, the smoke collecting cavity mechanism 20 will not be deformed or damaged, ensuring that the smoke collecting cavity mechanism 20 always has a good use effect.

[0080] In an alternative embodiment, as Figures 2 to 4As shown, the installation mechanism 80 can be fixedly connected to the front side plate assembly 212, the rear side plate assembly 213, and the support frame 22 respectively. Since different positions of the smoke collecting chamber mechanism 20 are fixedly connected to the installation mechanism 80, a good stable support effect of the smoke collecting chamber mechanism 20 on the installation mechanism 80 and the driving device 10 can be achieved.

[0081] In an alternative embodiment, as Figure 10 shown, the first reinforcing member 2122 further includes a fourth flanging 21221, and the installation mechanism 80 abuts against and is fixed to the fourth flanging 21221, thereby realizing a stable connection between the front side plate assembly 212 and the installation mechanism 80.

[0082] In an alternative embodiment, the installation mechanism 80 can also be fixedly connected to at least one of the front side plate assembly 212, the rear side plate assembly 213, and the support frame 22, and a good connection and fixing effect between the installation mechanism 80 and the smoke collecting chamber mechanism 20 can also be achieved. It should be noted that the installation mechanism 80 can be fixedly connected to at least one of the front side plate assembly 212, the rear side plate assembly 213, the upper end plate 216, the bottom plate 211, and the support frame 22. The more relevant structures the installation mechanism 80 is connected to, the better the weight of the driving device 10 and the main chassis 60 can be dispersed, and the deformation risk of the smoke collecting chamber mechanism 20 can be effectively reduced.

[0083] In an alternative embodiment, as Figure 9 and Figure 10 shown, the main chassis 60 is fixedly connected to the support frame 22, the upper end plate 216, the rear side plate assembly 213, and the installation mechanism 80. The weight of the main chassis 60 can be dispersed to the front side plate assembly 212, the rear side plate assembly 213, the upper end plate 216, the bottom plate 211, the support frame 22, and the installation mechanism 80. Each part of the smoke collecting chamber mechanism 20 is subjected to relatively small forces, and there is no problem of concentrated force on each part of the smoke collecting chamber mechanism 20, so that the deformation risk of the smoke collecting chamber mechanism 20 can be effectively reduced.

[0084] In an alternative embodiment, as Figure 9 shown, the support frame 22 includes a first support beam 222 and a second support beam 223 arranged at intervals in the left-right direction. The first support beam 222 includes a first support beam body 2222 and a first flanging 2221 fixedly connected. The first support beam body 2222 is fixedly connected to the smoke collecting hood 21, and the first flanging 2221 abuts against and is fixedly connected to the left side wall 61 of the main chassis 60, thereby realizing a stable connection between the first support beam 222 and the main chassis 60.

[0085] In an alternative embodiment, as Figure 9As shown, the second support beam 223 includes a second support beam body 2232 and a second flange 2231 that are fixedly connected. The second flange 2231 abuts against and is fixedly connected to the right side wall 62 of the main chassis 60, thereby achieving a firm connection between the second support beam 223 and the main chassis 60.

[0086] In summary, through the combined cooperation of the first support beam 222 and the second support beam 223, the first support beam 222 and the second support beam 223 can jointly support the main chassis 60 in the left-right direction of the main chassis 60, thereby achieving a firm support of the support frame 22 for the main chassis 60.

[0087] As Figure 10 shown, the upper region of the rear side plate assembly 213 protrudes towards the rear side of the rear side plate assembly 213 to form a socket groove 21311. The rear side wall 63 of the main chassis 60 is inserted into the socket groove 21311 and fixedly connected to the upper region of the rear side plate assembly 213, which can achieve a quick positioning and assembly effect between the rear side plate assembly 213 and the main chassis 60.

[0088] As Figure 10 shown, the upper end plate 216 includes an upper end plate body 2161 and a third flange 2162. An insertion opening 21611 is formed on the upper end plate body 2161. The third flange 2162 extends from the insertion opening 21611. The main chassis 60 is inserted into the insertion opening 21611, and the third flange 2162 abuts against and is fixed to the front side wall 64 of the main chassis 60, which can achieve a firm connection between the upper end plate 216 and the main chassis 60. In other alternative embodiments, the third flange 2162 can also abut against and be fixedly connected to the left side wall 61, the right side wall 62, or the rear side wall 63.

[0089] In an alternative embodiment, as Figure 3 、 Figure 4 and Figure 11 shown, the installation mechanism 80 includes a plurality of connecting beams 811. The plurality of connecting beams 811 jointly form an accommodation space 84. At least part of the driving device 10 is accommodated in the accommodation space 84. While ensuring good strength of the installation mechanism 80, it can also achieve a compact arrangement of the installation mechanism 80 and the driving device 10, and can reasonably place the installation mechanism 80 and the driving device 10 in the limited space within the smoke collecting hood 21, realizing the rational utilization of the limited space.

[0090] It should be noted that two adjacent connecting beams 811 can be fixed in various ways such as welding, pin fixing, screw fixing, and snap fixing, all of which can achieve the stable connection of two adjacent connecting beams 811. In an alternative embodiment, multiple connecting beams 811 can be formed by bending a whole cross beam, which has a simple structure and is convenient for manufacturing. The connection position of two adjacent connecting beams 811 can undergo plastic deformation to produce a work hardening effect, which can further improve the strength and hardness of the installation mechanism 80.

[0091] In an alternative embodiment, as Figure 11 shown, the connecting beam 811 includes a connecting plate 8111 and a reinforcing plate 8112. The reinforcing plate 8112 extends from one side of the connecting plate 8111, and the connecting plate 8111 and the reinforcing plate 8112 are arranged at an angle. By providing the reinforcing plate 8112, the strength and hardness of the connecting beam 811 can be effectively improved, thereby effectively improving the strength and hardness of the installation mechanism 80, and realizing the stable supporting effect of the installation mechanism 80 on the driving device 10. It should be noted that the reinforcing plate 8112 and the connecting plate 8111 can be formed by bending a whole plate, which is convenient for realizing the rapid manufacturing of the connecting beam 811. Due to being processed and manufactured by the bending process, the connection position of the reinforcing plate 8112 and the connecting plate 8111 can undergo plastic deformation to produce a work hardening effect, which can further improve the strength and hardness of the connecting beam 811 and the installation mechanism 80.

[0092] In an alternative embodiment, the connecting plate 8111 and the reinforcing plate 8112 can be fixed well by means such as welding, screw fixing, pin fixing, and snap component fixing.

[0093] Combined with Figures 2 to 4 、 Figure 12 and Figure 13 shown, the driving device 10 includes at least two driving mechanisms 11. Each driving mechanism 11 can independently drive the corresponding smoke baffle, and each smoke baffle is independently controlled by the corresponding driving mechanism 11, which can realize the flexible control of each smoke baffle.

[0094] In an alternative embodiment, combined with Figures 2 to 4 and Figure 11As shown, the driving mechanism 11 includes a first body 115 and a first output end 116 that can move linearly relative to the first body 115. The first body 115 can be pivotally connected to the mounting mechanism 80 about the front-back direction. The first output end 116 is fixedly connected to the smoke baffle. The first smoke baffle 30 includes a smoke baffle body 32 and a rotating shaft 31 provided thereon. The rotating shaft 31 extends in the front-back direction. A guiding groove 831 is formed on the mounting mechanism 80. The rotating shaft 31 is inserted into the guiding groove 831, and the extending direction of the guiding groove 831 is perpendicular to the front-back direction. When the first output end 116 moves linearly relative to the first body 115, the first output end 116 drives the rotating shaft 31 to slide along the guiding groove 831, and the first body 115 rotates relative to the mounting mechanism 80 about the front-back direction, thereby realizing the composite and complex curved movement path of the rotation and movement of the smoke baffle body 32 relative to the smoke collecting hood 21. When the first smoke baffle 30 is in the state of opening the first smoke inlet 21111, the outer contour edges of the first smoke baffle 30 are all spaced from the smoke collecting hood 21. That is to say, smoke can enter from all directions in the circumferential direction of the first smoke baffle 30, which can further improve the smoke extraction effect of the range hood compared with the smoke baffle body 32 that can only perform a single flipping movement.

[0095] In an alternative embodiment, as Figure 4 and Figure 11 shown, the mounting mechanism 80 includes a mounting main body 81 and a first mounting plate 82. The mounting main body 81 is fixedly connected to the smoke collecting cavity mechanism 20. The first mounting plate 82 is arranged on the mounting main body 81. The first body 115 is pivotally connected to the first mounting plate 82. Through the arrangement of the first mounting plate 82, it is convenient for the quick assembly of the first body 115 and the mounting mechanism 80. Exemplarily, the first body 115 can be connected to the first mounting plate 82 through a pivot shaft, wherein the pivot shaft extends in the front-back direction.

[0096] In an alternative embodiment, as Figure 4 and Figure 11 shown, the mounting mechanism 80 further includes a second mounting plate 83. The second mounting plate 83 is arranged on the mounting main body 81. The guiding groove 831 is formed on the second mounting plate 83. Through the arrangement of the second mounting plate 83, it is convenient for the quick assembly of the rotating shaft 31 and the guiding groove 831. Exemplarily, the second mounting plate 83 can be arranged as one, two, three or more. When the second mounting plate 83 is one, the overall structure of the range hood is simple; when the second mounting plate 83 is at least two, at least two second mounting plates 83 are arranged at intervals in the front-back direction, and at least two second mounting plates 83 jointly support the rotating shaft 31, and at least two second mounting plates 83 can achieve a relatively stable supporting effect on the rotating shaft 31.

[0097] In an alternative embodiment, the structure of the second smoke baffle 40 is the same as or similar to that of the first smoke baffle 30, and the connection manner between the second smoke baffle 40 and the installation mechanism 80 is the same as or similar to that between the first smoke baffle 30 and the installation mechanism 80.

[0098] In an alternative embodiment, as Figure 4 shown, the first smoke baffle 30 may further include a support plate 33. The support plate 33 is disposed on the baffle body 32, and the first output end 116 is fixedly connected to the support plate 33, facilitating the quick and stable assembly of the first output end 116 and the support plate 33.

[0099] In an alternative embodiment, the driving mechanism 11 includes a first body 115 and an output end capable of moving linearly relative to the first body 115. The first body 115 can be pivotally connected to the installation mechanism 80 about the front-rear direction (i.e., the extending direction of the first axis), the output end can be pivotally connected to the smoke baffle about the front-rear direction (i.e., the extending direction of the second axis), and the smoke baffle can be pivotally connected to the smoke collection chamber mechanism 20 about the front-rear direction (i.e., the extending direction of the third axis). When the output end moves linearly relative to the first body 115, the first body 115 can rotate relative to the installation mechanism 80, and the output end can push the smoke baffle to rotate relative to the installation mechanism 80 about the front-rear direction, thereby realizing the switching of the position of the smoke baffle by the driving mechanism 11. The connection manner between the driving mechanism 11 and the smoke baffle in this embodiment is simpler than that of the driving mechanism 11 and the smoke baffle mentioned in the foregoing embodiment. The relevant structure of this alternative embodiment is simpler, facilitating the quick assembly of the driving mechanism 11 and the installation mechanism 80 by the operator.

[0100] Embodiment Two

[0101] The range hood disclosed in Embodiment One needs to drive at least two smoke baffles to move by setting at least two sets of driving mechanisms 11. The number of driving mechanisms 11 that need to be set in the range hood of Embodiment One is relatively large. The overall volume of at least two sets of driving mechanisms 11 is relatively large, the structure is relatively complex, the energy consumption is relatively high, and the control method is relatively complex.

[0102] To solve the above problems, the present disclosure discloses a range hood in this embodiment. The structure of the range hood in this embodiment of the present disclosure is basically the same as that of the range hood in Embodiment One, and the main difference between the two lies in the setting form of the driving device 10.

[0103] As Figure 14 and Figure 15As shown in the figure, the driving device 10 of the present disclosure embodiment includes a driving mechanism 11 and a transmission assembly 12. At least two smoke baffle plates are in transmission connection with the driving mechanism 11 through the transmission assembly 12, and the driving mechanism 11 can synchronously flip at least two smoke baffle plates through the transmission assembly 12. Only one set of driving mechanism 11 is provided in the present disclosure embodiment to achieve synchronous flipping of at least two smoke baffle plates. Compared with the two sets of driving mechanisms 11 in Embodiment 1, the driving device 10 of the present disclosure embodiment has a relatively smaller volume, a relatively simpler structure, relatively lower energy consumption, and a relatively simpler control method.

[0104] In an alternative embodiment, as Figure 14 and Figure 15 shown, the smoke baffle plate includes a first smoke baffle plate 30 and a second smoke baffle plate 40. The first smoke baffle plate 30 and the second smoke baffle plate 40 are symmetrically arranged. The center line of the driving device 10 coincides with the symmetry line of the first smoke baffle plate 30 and the second smoke baffle plate 40, which is convenient for the driving device 10 to synchronously drive the first smoke baffle plate 30 and the second smoke baffle plate 40, and realizes a reasonable layout of the driving device 10, the first smoke baffle plate 30 and the second smoke baffle plate 40 in a limited space.

[0105] In an alternative embodiment, as Figure 14 and Figure 15 shown, the driving mechanism 11 includes a second body 111 and a second output end 112 that can move relative to it in the up and down direction (i.e., the first direction). The second body 111 is arranged on the mounting mechanism 80. The second output end 112 is respectively in transmission connection with the first smoke baffle plate 30 and the second smoke baffle plate 40 through the transmission assembly 12. By the simple linear motion of the second output end 112 relative to the second body 111, synchronous flipping of the first smoke baffle plate 30 and the second smoke baffle plate 40 can be achieved. The structure of the driving mechanism 11 is simple and convenient for installation. Specifically, the driving mechanism 11 can be a linear output driving mechanism. The linear output driving mechanism can be a linear output motor, a linear output cylinder, a linear guide rail, etc. It can also be a motor cooperating with a gear and rack assembly, a motor cooperating with a multi-link assembly, a motor cooperating with a crank-slider structure, etc. All structures or components that can achieve linear motion output are within the protection scope of this alternative embodiment.

[0106] In an alternative embodiment, as Figure 14 and Figure 15 shown, the transmission assembly 12 includes a mounting member 121, a first connecting rod 122, and a second connecting rod 123. The mounting member 121 is fixedly connected to the second output end 112. One end of the first connecting rod 122 is rotatably connected to the mounting member 121, and the other end of the first connecting rod 122 is rotatably connected to the first smoke baffle plate 30. One end of the second connecting rod 123 is rotatably connected to the mounting member 121, and the other end of the second connecting rod 123 is rotatably connected to the second smoke baffle plate 40.

[0107] If the setting position of the second output end 112 is at the upper end of the second body 111, when the second output end 112 is at a low position, the first smoke baffle 30 opens the first air inlet 21111, and when the second output end 112 is at a high position, the second smoke baffle 40 opens the second air inlet 21121. When the second output end 112 moves upward, that is, from Figure 14 state to Figure 15 state, the second output end 112 simultaneously drives the first hinge point of the first connecting rod 122 and the second hinge point of the second connecting rod 123 to move upward at the same time. The first connecting rod 122 and the second connecting rod 123 rotate around their respective hinge points, and the first connecting rod 122 and the second connecting rod 123 rotate in a trend of approaching each other. At the same time, the first connecting rod 122 drives the first smoke baffle 30 to rotate clockwise so that the first smoke baffle 30 closes and blocks the first air inlet 21111, and the second connecting rod 123 drives the second smoke baffle 40 to rotate counterclockwise so that the second smoke baffle 40 closes and blocks the second air inlet 21121. Through the up-and-down movement of the second output end 112, the synchronous opening or blocking of the first air inlet 21111 and the second air inlet 21121 is realized. By adjusting the position and stroke of the second output end 112, the opening and closing angles of the first smoke baffle 30 and the second smoke baffle 40 are adjusted, so that the air intake of the first air inlet 21111 and the second air inlet 21121 can be adjusted. In an optional embodiment, the second output end 112 can also be arranged at the lower end of the second body 111, and the above technical effects can also be achieved.

[0108] In an optional embodiment, as Figure 14 and Figure 15 shown, the range hood further includes a guiding mechanism 50. The guiding mechanism 50 is arranged between the mounting member 121 and the mounting mechanism 80. The guiding mechanism 50 is used to make the mounting member 121 move in the up-and-down direction without deviation, so as to realize the precise driving of the first smoke baffle 30 and the second smoke baffle 40.

[0109] In an optional embodiment, as Figure 14 and Figure 15 shown, the guiding mechanism 50 includes a guide rail 51 and a third slider 52. The guide rail 51 extends in the up-and-down direction and is fixedly connected to the mounting mechanism 80. The third slider 52 is fixedly connected to the mounting member 121 and can slide along the guide rail 51. Through the cooperation of the guide rail 51 and the third slider 52, the precise guiding effect of the mounting member 121 moving in the up-and-down direction can be realized.

[0110] In an optional embodiment, the guiding mechanism 50 is set to at least two, and two of the guiding mechanisms 50 are arranged in the front-back direction. By setting at least two guiding mechanisms 50, the mounting member 121 can be prevented from rotating during the up-and-down movement process.

[0111] Since the smoke collecting hood 21 is very thin, it is not easy to place a relatively large driving device 10 inside the smoke collecting hood 21. In an alternative embodiment, as Figure 14 and Figure 15 shown, the driving device 10 is located between the first smoke inlet 21111 and the second smoke inlet 21121. The driving device 10 is located inside the main chassis 60, effectively accommodating the driving device 10 by reasonably utilizing the space at the connection position between the main chassis 60 and the smoke collecting hood 21. The main chassis 60 can completely shield the driving device 10, and the overall shape of the range hood is more beautiful.

[0112] In an alternative embodiment, of course, part or all of the driving device 10 can also be arranged outside the main chassis 60, which is convenient for users to check and maintain the state of the driving device 10.

[0113] Embodiment III

[0114] The present disclosure embodiment discloses an oil fume treatment device 100. The structure of the oil fume treatment device 100 is basically the same as that of the oil fume treatment device 100 in Embodiment II. The main difference between the two is that as Figure 16 and Figure 17 shown, the structure of the transmission assembly 12 is different. Specifically, the transmission assembly 12 includes a mounting member 121, a connecting member 124, a first connecting rod 122, a first slider 125, a second connecting rod 123, and a second slider 126. The mounting member 121 is fixedly connected to the mounting mechanism 80, the connecting member 124 is fixedly connected to the second output end 112. One end of the first connecting rod 122 is rotatably connected to the first slider 125. The first slider 125 can slide relative to the connecting member 124 in the left-right direction (i.e., the second direction). The other end of the first connecting rod 122 is fixedly connected to the first smoke baffle 30. The middle part of the first connecting rod 122 is rotatably connected to the mounting member 121. One end of the second connecting rod 123 is rotatably connected to the second slider 126. The second slider 126 can slide relative to the connecting member 124 in the left-right direction. The other end of the second connecting rod 123 is fixedly connected to the second smoke baffle 40. The middle part of the second connecting rod 123 is rotatably connected to the mounting mechanism 80. Through this transmission assembly 12, it is also possible to achieve the synchronous flipping of the first smoke baffle 30 and the second smoke baffle 40 by only setting one set of driving mechanisms 11. Compared with the two sets of driving mechanisms 11 in Embodiment I, the driving device 10 in the present disclosure embodiment has a smaller volume, a simpler structure, lower energy consumption, and a simpler control method.

[0115] Specifically, as Figure 16 and Figure 17As shown in the figure, the connecting member 124 includes a connecting member body 1241 and a slide rail 1242 which are fixedly connected. The connecting member body 1241 is fixedly connected to the second output end 112. The slide rail 1242 extends in the left-right direction. The first slider 125 and the second slider 126 are arranged on the slide rail 1242 and can slide along the slide rail 1242. The slide rail 1242 can achieve a good guiding effect on the first slider 125 and the second slider 126.

[0116] Embodiment 4

[0117] An embodiment of the present disclosure discloses an oil fume treatment device 100. The structure of the oil fume treatment device 100 is basically the same as that of the oil fume treatment device 100 in Embodiment 2. The main difference between the two is that, as Figure 18 shown, the structure of the transmission component 12 is different. Specifically, the driving mechanism 11 is a motor. The motor includes a third body 113 and a third output end 114 that can rotate relative to it. The transmission component 12 includes a first gear 127 and a second gear 128 that are engaged with each other. The first smoke baffle 30 includes a rotating shaft 31 and a smoke baffle body 32 that are fixedly connected. The rotating shaft 31 is rotatably connected to the mounting mechanism 80. The second smoke baffle 40 includes a second rotating shaft 41 and a second smoke baffle body 42 that are fixedly connected. The second rotating shaft 41 is rotatably connected to the mounting mechanism 80. The first gear 127 is coaxially fixed to the rotating shaft 31, and the second gear 128 is coaxially fixed to the second rotating shaft. The rotating shaft 31 is coaxially fixed to the third output end 114. When the motor works, the third output end 114 drives the rotating shaft 31 and the smoke baffle body 32 to rotate. Under the transmission action of the first gear 127 and the second gear 128, the second rotating shaft 41 and the second smoke baffle body 42 can be synchronously flipped. The cooperation of the first gear 127 and the second gear 128 has high reliability, large load-bearing capacity, long service life and strong adaptability.

[0118] In an alternative embodiment, it may also be that the third output end 114 is coaxially fixed to the second rotating shaft, and the above effect can also be achieved.

[0119] Obviously, the above embodiments of the present invention are merely examples for clearly explaining the present invention, rather than limitations on the implementation manners of the present invention. For those of ordinary skill in the art, other different forms of changes or variations can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. Any modifications, equivalent replacements and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the claims of the present invention.
