[0040] In this application, "multiple" means two or more (including two).

[0041] In related technologies, range hoods can be installed in kitchen spaces or other environments where smoke exhaust is required. Range hoods can extract smoke to purify the air in the space, eliminate harmful gases, and remove odors.

[0042] Top-mounted range hoods have a top plate on the casing, with a section aligned with the air intake. When the range hood is working, as fumes enter and exit the smoke collection chamber through the air intake, a mixture of oil and water from the fumes adheres to the inner wall of the smoke collection chamber. The top plate of the casing also serves as the top plate of the smoke collection chamber, and this mixture accumulates on the lower surface of the top plate. After a certain amount, it falls downwards and onto the user's cooktop from the air intake, affecting the user experience.

[0043] Based on this, this application proposes a range hood that, on the one hand, can reduce the probability of oil dripping from the inside of the casing through the air intake by blocking the air intake with a first baffle, thereby improving the user experience; on the other hand, the first baffle is set on a guide module, and the movement of the first baffle can be guided by the guide module, thereby improving the stability of the movement of the first baffle. This improves the reliability of the position switching when the range hood is in the open state, the first baffle switches to the second position to avoid the air intake, and when the range hood is in the closed state, the first baffle switches to the first position to block the air intake.

[0044] The following is for reference. Figures 1-7 Description of a range hood 100 according to an embodiment of the present utility model.

[0045] like Figure 1 and Figure 5 As shown, this application provides a smoke hood 100, including: a housing 10, a guide module 20, a first baffle 30, and a drive component 40.

[0046] See Figure 2 , Figure 3 , Figure 4 as well as Figure 6 As shown, the suction panel 11 of the housing 10 is provided with a suction port 111, the guide module 20 is disposed inside the housing 10, the first baffle 30 is disposed on the guide module 20, and the drive component 40 is connected to the first baffle 30 to drive the first baffle 30 to movably switch between a first position that blocks the suction port 111 and a second position that avoids the suction port 111.

[0047] Specifically, a smoke collection chamber is formed inside the housing 10. At least one of the multiple plates surrounding the smoke collection chamber is formed as a suction panel 11. A suction port 111 is further formed on the suction panel 11 so that the oil fume airflow can enter the smoke collection chamber through the suction port 111. The guide module 20 is disposed inside the housing 10 and connects the drive member 40 to the first baffle 30. The first baffle 30 can switch between a first position and a second position inside the housing 10 under the guidance of the guide module 20.

[0048] The first baffle 30 can move within the housing 10, thereby blocking or opening the air intake 111. When the first baffle 30 is in the first position, the range hood 100 is in the off state. When the first baffle 30 is in the second position, the range hood 100 is in the on state. This means that the first baffle 30 can block the air intake 111 every time it switches to the first position, and the air intake 111 is open every time it switches to the second position, so as to ensure that the flow resistance of the oil fume airflow is small and the suction power of the range hood 100 can be kept stable.

[0049] It should be noted that the oily fumes enter the interior of the housing 10 through the air intake 111 and oil adheres to the inner wall of the smoke collection chamber inside the housing 10. In the direction of the airflow, the oil adhering to the plate downstream of the air intake 111 may drip through the air intake 111. However, the oil dripping from the interior of the housing 10 to the air intake 111 can be received by the first baffle 30, which can prevent oil from dripping outward from the air intake 111 when the range hood 100 is turned off. At the same time, it is impossible to observe the internal structure of the housing 10 through the air intake 111, which can improve the aesthetics of the range hood 100 and give it a refined appearance.

[0050] Meanwhile, the guide module 20 is installed inside the housing. The first baffle 30 can switch between the first position and the second position along the direction of movement under the guidance of the guide module 20. The first baffle 30 has better movement stability and can reduce the probability of the first baffle 30 getting stuck or shaking. This further improves the blocking effect of the first baffle 30 on the air intake 111 in the first position, effectively realizes oil receiving, and reduces the probability of oil dripping through the air intake 111.

[0051] According to the embodiments of this application, the range hood 100, on the one hand, by blocking the air intake 111 in the first position by the first baffle 30, can catch the oil dripping from inside the casing 10, reducing the probability of oil dripping onto the stove, which can improve the user experience and initially improve the aesthetics of the range hood 100. On the other hand, the guide module 20 can guide the movement of the first baffle 30, which can improve the stability of the movement of the first baffle 30, thereby improving the stability and reliability of the first baffle 30 in blocking the air intake 111.

[0052] like Figure 2 , Figure 3 , Figure 4 as well as Figure 6 As shown, according to some embodiments of this application, the housing 10 has a mounting opening 101 on one side of the first baffle 30 in the direction of movement, the housing 10 has a cover plate 14, the cover plate 14 covers the mounting opening 101, and the guide module 20, the first baffle 30 and the drive component 40 are all assembled to the housing 10 along the mounting opening 101.

[0053] Specifically, the smoke collection chamber defined by the housing 10 has an installation port 101 that is open on the side of the first baffle 30 in the direction of movement. The guide module 20, the first baffle 30 and the drive component 40 can be pre-assembled into a sub-assembly, and the sub-assembly can be further assembled into the housing 10 through the installation port 101. After the assembly is completed, the installation port 101 is further sealed by the cover plate 14 to complete the overall assembly of the smoke machine 100.

[0054] In this way, on the one hand, the guide module 20, the first baffle 30 and the drive component 40 are all assembled to the housing 10 along the mounting port 101, which can reduce the assembly difficulty and improve the assembly efficiency. On the other hand, after the mounting port 101 is blocked by the cover plate 14, the sealing performance of the mounting port 101 area is better, which can reduce the pressure loss during the oil fume extraction process, so that the suction force in the air intake 111 area can remain stable, thereby improving the oil fume extraction effect of the range hood 100.

[0055] Combination Figure 2 , Figure 4 as well as Figure 6As shown, according to some embodiments of this application, the housing 10 is provided with a connecting end plate 12 on the other side of the movement direction of the first baffle 30, and the guide module 20 includes: a first plate 21, which is connected to the connecting end plate 12.

[0056] Among them, one of the multiple plates surrounding the smoke collection chamber in the housing 10 is formed as the connecting end plate 12. The connecting end plate 12 and the mounting port 101 are arranged opposite to each other in the direction of movement of the first baffle 30. The first plate 21 of the guide module 20 can be connected to the connecting end plate 12 to realize the assembly of the guide module 20, the first baffle 30 and the drive component 40 in the housing 10.

[0057] It is understood that the suction panel 11 is used to define the mounting port 101 on one side of the first baffle 30's movement direction, and the suction panel 11 is connected to the connecting end plate 12 on the other side of the first baffle 30's movement direction. The suction panel 11 is connected to the side plate 15 of the housing in other directions that have a non-right angle with the first baffle 30's movement direction, so that the smoke collection chamber is defined by the suction panel 11, the connecting end plate 12, the side plate 15, and the cover plate 14. The first plate 21 is connected to the connecting end plate 12, and the two sides of the guide module 20 can be spaced apart from the side plate 15 so that the guide module 20 is set inside the housing 10. The guide module 20, the first baffle 30, and the drive component 40 can all be covered within the outer surface of the housing 10, which can improve the overall appearance of the range hood 100.

[0058] Meanwhile, the assembly and fixing of the first plate 21 and the connecting end plate 12 are simultaneously achieved in the assembly direction of the guide module 20. That is, while the guide module 20 is pushed into the housing 10 through the mounting port 101, the relative setting of the first plate 21 and the connecting end plate 12 can be completed, which can also reduce the assembly difficulty and improve the assembly efficiency.

[0059] Combination Figure 2 , Figure 3 as well as Figure 4 As shown, according to some embodiments of this application, a first positioning part 211 is provided on the first plate 21, and a second positioning part 121 is provided on the connecting end plate 12 to cooperate with the first positioning part 211 to position the guide module 20.

[0060] Specifically, the first positioning part 211 is constructed as a plug-in protrusion, and the second positioning part 121 is constructed as a plug-in hole that mates with the plug-in protrusion. For example, the plug-in protrusion is formed as a positioning pin, a snap fastener, etc., and the corresponding plug-in hole is formed as a positioning hole. The positioning pin or snap fastener is inserted into the positioning hole, which can not only fix the connecting end plate 12 and the first plate 21, but also achieve positioning between the two. When the guide module 20 is installed along the assembly direction, the positioning and mating of the connecting end plate 12 and the first plate 21 can be achieved, which can improve the assembly accuracy and facilitate the subsequent further fastening of the connecting end plate 12 and the first plate 21 by fasteners (such as screws).

[0061] It is understandable that the connecting end plate 12 can be directly connected and fixed to the first plate 21 through the cooperation of the first positioning part 211 and the second positioning part 121. The other side of the connecting end plate 12 can be correspondingly formed as the panel of the range hood 100. The area where the guide module 20 is connected to the connecting end plate 12 has no exposed fixing structure on the appearance surface, which can improve the aesthetics. Alternatively, the side of the connecting end plate 12 away from the first plate 21 can be further equipped with the head of the range hood 100, thereby hiding the fasteners that fix the first plate 21 and the connecting end plate 12, which can improve the overall aesthetics of the range hood 100.

[0062] like Figure 2 , Figure 3 as well as Figure 6 As shown, according to some embodiments of this application, the drive member 40 is mounted on the side of the first plate 21 opposite to the connecting end plate 12.

[0063] That is, the first plate 21 has a side surface facing the connecting end plate 12 and another side surface opposite to it. The side surface is attached and fixed to the connecting end plate 12, and the other side surface is used to assemble the drive component 40.

[0064] On the one hand, the drive component 40 can form a sub-assembly with the guide module 20, reducing assembly difficulty and improving assembly efficiency. On the other hand, the arrangement between the first plate 21, the connecting end plate 12 and the drive component 40 is more compact, which can improve the space occupation inside the housing 10, realize a compact setting, and facilitate the overall thinning and miniaturization of the smoke machine 100.

[0065] See Figure 3 and Figure 4 As shown, according to some embodiments of this application, the guide module 20 further includes: a second plate 22, which is connected to both ends of the first plate 21, and the first plate 21 and the second plate 22 enclose a receiving space for accommodating the driving member 40 and the first baffle 30, and the second plate 22 is movably connected to the first baffle 30.

[0066] Specifically, the second plate 22 is located at both ends of the length of the first plate 21. The first plate 21 and the second plate 22 form a U-shaped bracket, and the first plate 21 and the second plate 22 enclose an accommodating space. The driving component 40 and the first baffle 30 can both be set in the accommodating space, which can further realize the compact layout of multiple components inside the housing 10 and improve space occupation. The second plate 22 extends along the movement direction of the first baffle 30 so that the first baffle 30 can be assembled in the accommodating space along the movement direction. This can also reduce the probability of interference between the first baffle 30 and surrounding components during the movement, and improve the movement reliability and stability of the first baffle 30.

[0067] like Figure 3 , Figure 4 as well as Figure 6 As shown, according to some embodiments of this application, the guide module 20 further includes a guide component 23, which has a fixed part 231 and a moving part 232 that are movablely engaged. The fixed part 231 is connected to the second plate 22, and the moving part 232 is connected to the first baffle 30.

[0068] Specifically, the fixing part 231 is fixed on the second plate 22, while the moving part 232 is movably engaged with the fixing part 231 so that the first baffle 30 connected to the moving part 232 can move relative to the housing 10. This can further improve the smoothness of the movement of the first baffle 30 and reduce the movement resistance of the first baffle 30, so that the driving power corresponding to the driving component 40 can be smaller, thereby reducing the cost of the driving component 40 and reducing the overall cost of the range hood 100.

[0069] The fixed part 231 and the moving part 232 can be constructed as a guide rail and a slider, or as a slide and a slide rail, respectively. This application does not make any specific limitation.

[0070] Combination Figure 3 and Figure 7 As shown, according to some embodiments of this application, the housing 10 further includes: a first plate 13, the first plate 13 being located on the side of the first baffle 30 away from the air intake 111, and a connecting plate 221 being provided on the side of the second plate 22 facing the first plate 13, the connecting plate 221 being connected to the first plate 13.

[0071] Specifically, the first plate 13 and the suction panel 11 can be arranged sequentially in the height direction. The connecting end plate 12 and the side plate 15 surround the periphery of the first plate 13 and the suction panel 11 to define the smoke collection chamber. The first plate 13 is connected to the connecting plate 221 provided on the second plate 22.

[0072] In this way, on the one hand, the connecting plate 221 is connected to the first plate 13, and the connecting end plate 12 is connected to the first plate 21, which can enable the guide module 20 to be assembled and fixed in at least two different directions, thereby improving the stability and reliability of the guide module 20 within the housing 10. On the other hand, the connecting plate 221 is assembled with the first plate 13 in the height direction, and there is no fastening structure between the side plate 15 and the guide module 20, so that the left and right sides of the housing can be formed into flat surfaces. The top side surface, the front side surface blocked by the head, and the rear side surface defined by the cover plate 14 are all invisible surfaces and are not used as the appearance observation surface of the housing 10, which can improve the overall aesthetics of the smoke machine 100.

[0073] like Figure 7 As shown, according to some embodiments of this application, a connecting recess 131 extending toward the second plate 22 is formed on the first plate 13, and the bottom surface of the connecting recess 131 is connected to the connecting plate 221.

[0074] Therefore, by setting the connecting recess 131, at least a portion of the first plate 13 can extend toward the interior of the housing 10 and be used to connect with the connecting plate 221. The height dimension of the corresponding second plate 22 does not need to be set too large, which is beneficial to the thinning design of the housing 10 in the height direction and can improve the space occupation of the range hood 100. The side of the connecting recess 131 away from the smoke collection cavity can be used to accommodate fasteners, so that the fasteners can be located below the outer surface of the first plate 13 and can also avoid the fasteners protruding from the first plate 13, thereby reducing the difficulty of arranging the range hood 100.

[0075] like Figures 1-6 As shown, according to some embodiments of this application, the first baffle 30 is configured as an oil receiving tray, and the range hood 100 includes at least one set of cleaning components. The cleaning components are disposed inside the housing 10 and are adapted to move in conjunction with or relative to the first baffle 30 to scrape the side surface of the first baffle 30 facing the air intake 111, and / or the side surface of the first plate 13 of the housing 10 facing the first baffle 30, and / or the location of the oil leakage hole of the housing 10.

[0076] The cleaning components may include a first cleaning component 51, a second cleaning component 52, and a third cleaning component 53.

[0077] like Figures 1-4 As shown, in the first embodiment of this application, a second baffle 60 is provided below the first plate 13. The second baffle 60 is located at least on the part of the first plate 13 opposite to the air intake 111 to reduce the adhesion of oil on the first plate 13. The side surface of the second baffle 60 facing the air intake 111 can be scraped by the first cleaning component 51.

[0078] like Figure 5 and Figure 6 As shown, in the second embodiment of this application, no plate structure is provided below the first plate 13. During the movement of the first baffle 30 and the first cleaning component 51, the surface of the first plate 13 facing the air intake 111 can be scraped.

[0079] Specifically, the first cleaning component 51 can be disposed on the first baffle 30 and can move synchronously with the first baffle 30. During the switching between the first and second positions of the first baffle 30, the first cleaning component 51 contacts the first plate 13 or the second baffle 60 disposed on the first plate 13, thereby scraping the surface of the first plate 13 or the second baffle 60 facing the air intake 111. The second cleaning component 52 can be disposed on the second plate 22 or on the housing 10, and positioned on the side of the first baffle 30 facing the air intake 111. On the side, the first baffle 30 is located on one side of the air intake 111 in the direction of movement of the first baffle 30, so that during the movement of the first baffle 30, the first baffle 30 contacts the second cleaning component 52 and scrapes the surface of the first baffle 30 facing the air intake 111. The third cleaning component 53 can be installed inside the housing 10, and at least a part of the third cleaning component 53 can extend into the oil collection tank. During the movement of the first baffle 30, the third cleaning component 53 can be pushed to move so that the third cleaning component 53 can scrape at least the location of the oil leakage hole in the oil collection tank.

[0080] The first cleaning component 51 moves synchronously with the first baffle 30, the second cleaning component 52 moves relative to the first baffle 30, and the third cleaning component 53 moves in conjunction with the first baffle 30. These components respectively achieve the scraping of the surface of the first plate 13 or the second baffle 60 facing the air intake 111, the scraping of the surface of the first baffle 30 itself facing the air intake 111, and the scraping of the oil leakage hole.

[0081] Understandably, the first baffle 30 can receive oil dripping from the first plate 13 and / or the second baffle 60. The surface of the first baffle 30 facing the air intake 111 can be scraped by the second cleaning component 52, which can reduce the probability of oil dripping from the air intake 111 when the range hood 100 is off. When the range hood 100 is on, the oil on the first plate 13 or the second baffle 60 can be scraped by the first cleaning component 51 in the initial stage, which can reduce the probability of oil dripping from the air intake 111 when the range hood 100 is on. The third cleaning component 53 is linked with the first baffle 30, which can reduce the probability of the oil leakage hole becoming blocked, so that the oil in the oil collection tank can be discharged in time.

[0082] Meanwhile, the combined use of the first cleaning component 51, the second cleaning component 52, and the third cleaning component 53 can reduce oil residue in the smoke collection chamber and reduce the probability of stubborn oil stains appearing on the oil collection tank, the first baffle 30, the second baffle 60, or the first plate 13, thereby reducing the difficulty of cleaning the inside of the casing 10 and improving the user experience.
