[0047] In this application, "multiple" means two or more (including two).

[0048] 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.

[0049] 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.

[0050] Based on this, this application proposes a range hood that selectively blocks or avoids the air intake by means of a first baffle. When the first baffle blocks the air intake, the first cleaning component scrapes the surface of the first baffle facing the air intake, which can reduce the probability of oil dripping through the air intake and improve the user experience.

[0051] The following is for reference. Figures 1-11 Description of a range hood 100 according to an embodiment of the present utility model.

[0052] like Figure 1 , Figure 2 , Figure 3 as well as Figure 9 , Figure 10 As shown, this application provides a range hood 100, including: a housing 10, a first baffle 30, and a first cleaning assembly 50.

[0053] The first baffle 30 is movably disposed within the housing 10 to switch between a first position that blocks the air intake 121 and a second position that avoids the air intake 121. The first cleaning component 50 is disposed within the housing 10 and is located on the side of the first baffle 30 facing the air intake 121 and is used to scrape the surface of the first baffle 30 facing the air intake 121.

[0054] Specifically, the first baffle 30 can move within the housing 10, thereby blocking or opening the air intake 121. 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 each time the first baffle 30 switches to the first position, it can be scraped by the first cleaning component 50 to ensure that the position where the first baffle 30 blocks the air intake 121 is clean each time it is in the off state. When the first baffle 30 switches to the second position, the air intake 121 is open to ensure that the flow resistance of the oil fume airflow is small and the suction power of the range hood 100 remains stable.

[0055] It should be noted that the oily fumes enter the housing 10 through the air intake 121, and oil will adhere to the surface of the first baffle 20. Before the first baffle 20 moves to the first position to block the air intake 121, the surface of the first baffle 20 facing the air intake 121 can be scraped by the first cleaning component 50 to ensure that the surface of the first baffle 20 facing the air intake 121 is clean. That is, the oil dripping from the inside of the housing 10 to the air intake 121 can be received by the first baffle 20, and the surface of the first baffle 20 itself facing the air intake 121 is also clean. This can prevent oil from dripping out of the air intake 121 when the range hood 100 is in the off state.

[0056] According to the embodiments of this application, the range hood 100, by setting a first baffle 30 and a first cleaning component 50, allows the air intake 121 to be open when the range hood 100 is turned on, and the air intake 121 to be blocked when the range hood 100 is turned off. The side wall of the first baffle 30 blocking the air intake 121 is in a clean state. On the one hand, it can reduce the probability of oil dripping from the air intake 121 when the range hood is turned off, reduce the probability of the stove being contaminated, and improve the user experience. On the other hand, the blocked air intake 121 area can also improve the aesthetics of the range hood 100 and give the range hood 100 a refined look.

[0057] like Figure 6 and Figure 7 As shown, according to some embodiments of this application, the first cleaning component 50 is located on the side of the first baffle 30 facing the air intake 121, so that when the first baffle 30 passes the first cleaning component 50, the first cleaning component 50 scrapes the surface of the first baffle 30 facing the air intake 121.

[0058] Specifically, the first cleaning component 50 is located on the side of the first baffle 30 facing the air intake 121, and the position of the first cleaning component 50 is fixed relative to the air intake 121. Thus, when the first baffle 30 moves relative to the air intake 121 and passes the first cleaning component 50, the side of the first cleaning component 50 facing the lower surface of the first baffle 30 contacts the lower surface of the first baffle 30 to complete the oil scraping. After completing the oil scraping, the first baffle 30 moves to the area where the air intake 121 is located. The surface of the first baffle 30 facing the air intake 121 can remain clean, thereby preventing oil on the first baffle 30 from dripping through the air intake 121.

[0059] In the direction of movement of the first baffle 30, the first cleaning component 50 should be located on one side of the air intake 121, and the movement path of the first baffle 30 should have a starting point (second position) and an ending point (first position). When the first baffle 30 is at the starting point, the first baffle 30 and the first cleaning component 50 should be located on the same side of the air intake 121, and the distance between the first cleaning component 50 and the air intake 121 should be greater than or equal to the distance between the first baffle 30 and the air intake 121, so as to ensure that the area of ​​the first baffle 30 that will pass through the air intake 121 can be completely scraped by the first cleaning component 50, thereby improving the cleaning effect of the first cleaning component 50 on the first baffle 30 and effectively preventing the oil on the first baffle 30 from dripping through the air intake 121.

[0060] like Figure 7 As shown, according to some embodiments of this application, the first cleaning assembly 50 includes a first scraper 52, which is located on one side of the air intake 121 in the direction of movement of the first baffle 30. The first scraper 52 has a dimension L1 in the direction of movement perpendicular to the first baffle 30, and the air intake 121 has a dimension L2 in the direction of movement perpendicular to the first baffle 30. L1 is greater than or equal to L2, so that the first scraper 52 is used to scrape at least the area of ​​the first baffle 30 used to block the air intake 121.

[0061] It should be noted that the first scraper 52 can be arranged in the direction perpendicular to the movement direction of the first baffle 30. For example, if the first baffle 30 moves along the width direction of the housing 10, the first scraper 52 can be arranged in the length direction of the housing 10. If the first baffle 30 moves along the length direction of the housing 10, the first scraper 52 can be arranged in the width direction of the housing 10.

[0062] Specifically, the size of the first scraper 52 in the direction perpendicular to the movement of the first baffle 30 is greater than or equal to the opening size of the air intake 121 in the direction perpendicular to the movement of the first baffle 30. This allows the first baffle 30 to be scraped at least in the area passing through the air intake 121 during its movement. The first cleaning component 50 can scrape a larger area of ​​the first baffle 30, thereby improving the cleanliness of the first baffle 30 and making the first cleaning component 50 more effective in preventing oil from dripping from the surface of the first baffle 30 facing the air intake 121.

[0063] See Figure 7 As shown, the first cleaning assembly 50 further includes: a first mounting base 51, a first scraper 52 mounted on the first mounting base 51, the first mounting base 51 being connected to the housing 10, the first mounting base 51 having a receiving groove on the side facing the first baffle 30, the first scraper 52 being disposed in the receiving groove and at least partially extending out of the receiving groove and contacting the first baffle 30.

[0064] Specifically, the first mounting base 51 can be constructed as a U-shaped mounting base. The first mounting base 51 includes a base plate and side plates located on both sides of the base plate. The base plate is used to connect with the housing 10 so that the position of the first cleaning assembly 50 relative to the air intake 121 can remain unchanged. The side plates on both sides and the base plate define a receiving groove. The first scraper 52 can be set in the receiving groove, which can improve the fixing effect of the first mounting base 51 on the first scraper 52. At least a part of the first scraper 52 extends out of the receiving groove and contacts the first baffle 30, which can realize the scraping of the first baffle 30. The two side plates of the first mounting base 51 can limit the first scraper 52 on both sides of the first baffle 30 in the direction of movement, which can reduce the movement of the first scraper 52, improve the contact stability and reliability of the first scraper 52 and the first baffle 30, thereby improving the oil scraping effect of the first cleaning assembly 50 on the first baffle 30.

[0065] exist Figure 7 In the embodiment shown, the open side of the first mounting base 51 is provided with a first limiting part 511, and the part of the first scraper plate 52 installed into the receiving groove is provided with a second limiting part 521 that cooperates with the first limiting part 511.

[0066] The first limiting part 511 can be constructed as an L-shaped limiting plate, and a limiting groove can be formed between the limiting plate and the side plate of the first mounting base 51. Protrusions can be provided on both sides of the width of the first scraping plate 52, and the protrusions extend into the limiting groove to limit the first scraping plate 52, improve the connection stability and reliability between the first scraping plate 52 and the first mounting base 51, thereby improving the oil scraping effect. At the same time, the setting of the protrusions can also improve the structural rigidity of the first scraping plate 52 itself, reduce the probability of bending and twisting deformation of the first scraping plate 52, and further improve the contact stability between the first scraping plate 52 and the first baffle 30, thereby improving the oil scraping effect.

[0067] like Figure 4 , Figure 5 as well as Figure 6 , Figure 11 As shown, according to some embodiments of this application, the range hood 100 further includes a drive member 70, which is disposed inside the housing 10 and is connected to the first baffle 30 to drive the first baffle 30 to switch between a first position that blocks the air intake 121 and a second position that avoids the air intake 121.

[0068] Specifically, the drive component 70 can be fixed on the housing 10 or on a non-moving component inside the housing 10. The power output end of the drive component 70 can be connected to the first baffle 30 so that the drive component 70 can drive the first baffle 30 to switch between a first position that blocks the air intake 121 and a second position that avoids the air intake 121.

[0069] Understandably, in the first position, the first baffle 30 can block the air intake 121. At this time, the air intake 121 can be blocked, which can also prevent the oil inside the casing 10 from dripping through the air intake 121, and make the internal structure of the range hood 100 impossible to observe through the air intake 121. It can also improve the aesthetics of the range hood 100 and give it a refined look, thereby enhancing the product's competitiveness. When the first baffle 30 is in the second position, it can avoid the air intake 121, so that the resistance to the flow of smoke during the operation of the range hood 100 is smaller and the smoke extraction effect is better.

[0070] The driving component 70 in this application embodiment can be any form of transmission assembly that uses a driving cylinder, a driving hydraulic cylinder, a linear motor, or a rotary motor to convert rotation into linear motion; this application does not impose any specific limitations.

[0071] like Figure 5 and Figure 11 As shown, according to some embodiments of this application, the range hood 100 further includes a guide assembly 80, which is disposed inside the housing 10 and is arranged along the movement direction of the first baffle 30 to guide the movement of the first baffle 30.

[0072] The guide component 80 is set in the direction corresponding to the movement direction of the first baffle 30, so as to guide the movement of the first baffle 30 through the guide component 80, so that the movement of the first baffle 30 between the first position and the second position is more stable, reducing the probability of the first baffle 30 getting stuck or moving, and making the contact stability between the first baffle 30 and the first scraper 52 more stable, which can further improve the oil removal effect on the surface of the first baffle 30 facing the air intake 121.

[0073] Combination Figure 5 and Figure 11 As shown, according to some embodiments of this application, the guide assembly 80 includes a fixed part 81 and a moving part 82 that are movable and cooperate with each other. The moving part 82 is connected to the first baffle 30, and the fixed part 81 is connected to the housing 10.

[0074] Specifically, the fixing part 81 can be fixed to the housing 10, or it can be disposed inside the housing 10 and fixed to a component of the housing 10. The moving part 82 can move in conjunction with the fixing part 81 so that the first baffle 30 connected to the moving part 82 can move relative to the housing 10. The arrangement of the fixing part 81 and the moving part 82 can further improve the movement stability 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 70 can be smaller, thereby reducing the cost of the driving component 70 and reducing the overall cost of the range hood 100.

[0075] The fixed part 81 and the moving part 82 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.

[0076] Furthermore, the first baffle 30 can be configured as an oil receiving tray, and the range hood 100 also includes a second cleaning component 40, which is disposed on the first baffle 30. The second cleaning component 40 is used to move with the first baffle 30 and scrape the side surface of the housing 10 facing the air intake 121.

[0077] It should be noted that in the first embodiment of this application, the second cleaning component 40 is used to move with the first baffle 30 and scrape the second baffle 20 disposed on the housing 10.

[0078] Specifically, combined Figure 2 and Figure 3 As shown, the housing 10 has a first plate 11 and a suction panel 12. The suction panel 12 has a suction port 121. A second baffle 20 is disposed inside the housing 10. The projection of the second baffle 20 onto the suction panel 12 at least covers the portion of the first plate 11 that is aligned with the suction port 121. The first baffle 30 is movably disposed inside the housing 10. A second cleaning component 40 is disposed on the first baffle 30. The second cleaning component 40 is used to move with the first baffle 30 and scrape the surface of the second baffle 20 facing the suction port 121.

[0079] Specifically, the suction panel 12 defines an air intake 121, through which the oil fume airflow enters the housing 10. A second baffle 20 is disposed inside the housing 10. In the direction of oil fume airflow, the second baffle 20 can be located upstream of the first plate 11, and can at least cover the portion of the first plate 11 directly opposite the air intake 121. This allows the oil fume airflow to act on the second baffle 20, rather than directly on the first plate 11, thus improving the flow of oil fume. Oil accumulates on the plate 11. The second cleaning component 40 is movably mounted on the first baffle 30 so that the second cleaning component 40 can move with the first baffle 30. When passing the second baffle 20, the second cleaning component 40 scrapes the oil adhering to the lower surface of the second baffle 20 so that the oil on the area of ​​the second baffle 20 facing the air inlet 121 can be removed, so as to prevent the oil on the surface of the second baffle 20 facing the air inlet 121 from dripping out of the housing 10 through the air inlet 121.

[0080] In other words, the second cleaning component 40 can be mounted on the first baffle 30 and driven by the first baffle 30. The oil scraped off by the second cleaning component 40 from the second baffle 20 can be received by the first baffle 30. Especially when passing the air intake 121, the scraped oil can be prevented from dripping through the air intake 121.

[0081] Furthermore, the first baffle 30 is also located inside the housing 10. During the fume extraction process, the fume airflow will cause oil to adhere to the first baffle 30. As the first baffle 30 drives the second cleaning component 40 to move and scrape the second baffle 20, the first baffle 30 will pass through the air intake 121. There is a certain probability that the oil on the side of the first baffle 30 facing the air intake 121 will drip through the air intake 121. The first cleaning component 50 can be used to scrape the side of the first baffle 30 facing the air intake 121, so that the side of the first baffle 30 facing the air intake 121 can be kept clean, so as to prevent the oil accumulated on the first baffle 30 from dripping out through the air intake 121.

[0082] It should be noted that by scraping the surface of the second baffle 20 facing the air intake 121 with the second cleaning component 40, and scraping the surface of the first baffle 30 facing the air intake 121 with the first cleaning component 50, the cleanliness of the surfaces of the second baffle 20 and the first baffle 30 facing the air intake 121 can be improved, oil accumulation can be reduced, the probability of stubborn oil stains forming on the second baffle 20 and the first baffle 30 can be reduced, and the oil can be more effectively discharged from the inside of the housing 10, so that less oil accumulates inside the housing 10 and the cleaning inside the housing 10 is easier.

[0083] For example, the suction panel 12 and the first plate 11 can be arranged sequentially in a certain direction (e.g., in the height direction of the housing 10, in the front-back direction of the housing 10, or in the left-right direction of the housing 10). The second baffle 20 is located between the first plate 11 and the suction panel 12, and the first baffle 30 is located between the first plate 11 and the suction panel 12. The second cleaning component 40 is disposed on the first baffle 30 and located between the first baffle 30 and the second baffle 20 to scrape the side surface of the second baffle 20 facing the suction port 121. The first cleaning component 50 is located between the suction panel 12 and the first baffle 30 to scrape the side surface of the first baffle 30 facing the suction port 121.

[0084] In this way, by setting a second baffle 20 to block the part of the first plate 11 that is directly opposite the air intake 121, the second cleaning component 40 scrapes the second baffle 20, and the first cleaning component 50 scrapes the first baffle 30. On the one hand, it can prevent the area of ​​the second baffle 20 opposite to the air intake 121 from dripping oil onto the outside of the casing 10 through the air intake 121. It can also prevent the surface of the first baffle 30 facing the air intake 121 from dripping oil onto the outside of the casing 10 through the air intake 121 when the first baffle 30 passes the air intake 121, thereby improving the user experience. On the other hand, it can make the oil inside the casing 10 collect better, make it easier to drain the oil, and make the inside of the casing 10 cleaner, making it easier to clean the inside of the casing 10 in the future.

[0085] Of course, the structure of the range hood 100 in this application embodiment is not limited to this. In the second embodiment of this application, the second cleaning component 40 is used to move with the first baffle 30 and scrape the surface of the first plate 11 of the housing 10 facing the air intake 121.

[0086] Combination Figure 10 and Figure 11 As shown, the housing 10 has a first plate 11 and a suction panel 12. The suction panel 12 has a suction port 121. A first baffle 30 is movably disposed inside the housing 10. A first cleaning component 40 is disposed on the first baffle 30. The first cleaning component 40 is used to move with the first baffle 30 and scrape the surface of the first plate 11 facing the suction port 121. A second cleaning component 50 is disposed inside the housing 10. The second cleaning component 50 is used to scrape the surface of the first baffle 30 facing the suction port 121.

[0087] Specifically, the suction panel 12 defines the suction port 121, through which the oil fume airflow can enter the interior of the housing 10. In the direction of oil fume airflow, the first plate 11 is located downstream of the suction port 121. The oil fume airflow entering through the suction port 121 will act on the first baffle 11 and form oil adhesion on the first baffle 11.

[0088] The first cleaning component 40 is movably mounted on the first baffle 30, so that the first cleaning component 40 can move with the first baffle 30 and scrape the oil adhering to the lower surface of the first plate 11 when passing the first plate 11, so that the oil on at least the area of ​​the first plate 11 directly opposite the air inlet 121 can be removed, so as to prevent the oil on the surface of the first plate 11 facing the air inlet 121 from dripping out of the housing 10 through the air inlet 121.

[0089] In summary, by further configuring a second cleaning component 40, this application can scrape the lower surface of the first plate 11 or the second baffle 20 opposite to the air intake 121 inside the housing 10. This ensures that at the initial stage of each time the range hood 100 is turned on, the surface of the plate downstream of the air intake 121 that is opposite to the air intake 121 is clean, thereby reducing the probability of oil dripping onto the stove when the range hood is turned on and further improving the user experience of the range hood 100.

[0090] like Figure 4 and Figure 5 , Figure 11As shown, the second cleaning assembly 40 includes a second scraper 42 and a second mounting base 41. The second mounting base 41 is disposed on the side surface of the first baffle 30 facing the second baffle 20. The second scraper 42 is connected to the second mounting base 41 and extends toward the second baffle 20 and contacts the second baffle 20 to scrape the oil on the second baffle 20.

[0091] The second mounting base 41 may include a first connecting plate 411, an extension plate 413, and a second connecting plate 412. The first connecting plate 411 is connected to the second mounting base 41. One end of the extension plate 413 is connected to the first connecting plate 411, and the other end of the extension plate 413 is provided with the second connecting plate 412. The second scraper 42 is disposed on the second connecting plate 412 so that the second scraper 42 can contact the second baffle 20. The first connecting plate 411, the extension plate 413, and the second connecting plate 412 may be formed into a Z-shaped plate body so that the second scraper 42 can elastically abut against the second baffle 20, which can also improve the oil scraping effect of the second scraper 42.

[0092] Furthermore, the second scraper 42 may include a connecting plate 421 and a scraper 422. The connecting plate 421 is connected to the second connecting plate 412. The scraper 422 protrudes from the connecting plate 421 and extends toward the second baffle 20 to contact the second baffle 20. The second scraper 42 may also be provided with a support plate 423. The support plate 423 is connected to the connecting plate 421 and extends toward the first plate 11, while also being connected to the scraper 422. The support plate 423 can provide support for the scraper 422, thereby increasing the rigidity of the scraper 422 and improving the contact effect between the scraper 422 and the second baffle 20, which can further improve the oil scraping effect of the second scraper 42.

[0093] It is understood that the first plate 11 has an air outlet 111 located in the middle area of ​​the first plate 11. The first plate 11 has portions on both sides that are aligned with the air intake 121. The second baffle 20 is located between these portions and the air intake 121 to block the portion of the first plate 11 that is aligned with the air intake 121 and to avoid the portion of the air intake 121 that is aligned with the air outlet 111.

[0094] In the first embodiment, as Figure 2 and Figure 5As shown, the distance between the second baffle 20 and the first plate 11 gradually increases in the direction away from the air outlet 111. This allows the oil adhering to the second baffle 20 to flow away from the air outlet 111 along the inclined direction of the second baffle 20. It also gives the second baffle 20 a guiding effect, which can guide the oil fume airflow to the area where the air outlet 111 is located, reduce the flow resistance of the oil fume airflow, and improve the oil fume extraction effect. At least a part of the second cleaning component 40 (the second scraper 42) extends toward the second baffle 20 and contacts the second baffle 20. That is, the end face of the second scraper 42 toward the second baffle 20 is constructed as an inclined surface that contacts the second baffle 20, so as to improve the scraping effect of the second scraper 42.

[0095] In the second embodiment, combined with Figure 10 and Figure 11 As shown, the first plate 11 has an air outlet 111, and a protrusion 112 is formed on the first plate 11, which is arranged around the air outlet and extends toward the first baffle 30. The second cleaning assembly 40 is provided with a relief groove 424 that accommodates the protrusion 112 and contacts the protrusion 112.

[0096] Specifically, the first plate 11 has a downwardly extending protrusion 112 around the air outlet 111. The side of the protrusion 112 away from the first baffle 30 forms a mounting groove, which can be used to install the fan housing. This allows the suction force generated by the fan to be drawn downward through the air outlet 111, so that the flue gas can flow sequentially through the air inlet 121, the air outlet 112 and into the fan housing, and finally be discharged. The protrusion 112 can further cooperate with the clearance groove 424, which not only guides the movement of the second scraper 42 of the second cleaning assembly 40 and improves the stability of the movement of the second scraper 42, but also scrapes the area of ​​the first plate 11 adjacent to the protrusion 112 and the protrusion 112 during the movement of the second scraper 42, improving the scraping effect and preventing oil from adhering to the protrusion 112, which would cause the movement of the second scraper 42 to be stuck, and further improves the stability of the movement.

[0097] It should be noted that during the switching process between the first baffle 30 and the second position, the second cleaning component 40 can move synchronously with the first baffle 30 to scrape the second baffle 20. When the first baffle 30 is in the first position, the range hood 100 is in the off state, and when the first baffle 30 is in the second position, the range hood 100 is in the on state. This means that each time the first baffle 30 is switched to the first position, it can be scraped by the first cleaning component 50 to ensure that the area of ​​the first baffle 30 covering the air intake 121 is clean each time it is in the off state. And each time the first baffle 30 is switched to the second position, the second baffle 20 can be scraped by the second cleaning component 40 to ensure that the area of ​​the second baffle 20 opposite to the air intake 121 is clean at the beginning each time it is turned on, so as to avoid oil dripping from the second baffle 20 when it is turned on.

[0098] Of course, the range hood 100 can also have a cleaning mode. In the cleaning mode, the first baffle 30 can frequently switch between the first position and the second position to achieve powerful cleaning of the second baffle 20 and the surface of the first baffle 30 facing the air intake 121.

[0099] like Figure 3 , Figure 6 as well as Figure 8 As shown, according to some embodiments of this application, the range hood 100 further includes a third cleaning component 60, which is movably disposed within the housing 10 and is used to scrape the area where the oil leakage hole 131 of the housing 10 is located.

[0100] The casing 10 is also equipped with an oil collection tank 13. During the operation of the range hood 100, the liquefied oil in the oil fume airflow can accumulate in the oil collection tank 13. The oil on the second baffle 20 and the first baffle 30 can also flow into the oil collection tank 13 after being scraped by the second cleaning component 40 and the first cleaning component 50. The oil collection tank 13 is equipped with an oil drain hole 131. The oil drain hole 131 can drain the oil accumulated in the oil collection tank 13 into the oil collection box located below the oil collection tank 13 and connected to the casing 10. However, the oil accumulated in the oil collection tank 13 has a high viscosity, which may cause the oil drain hole 131 to become blocked, making it difficult to drain the oil into the oil collection box.

[0101] Based on this, the present application further provides a third cleaning component 60, which can at least be used to scrape the area where the oil leakage hole 131 is located, so as to clean the area where the oil leakage hole 131 is located, avoid the oil leakage hole 131 from becoming blocked, so that the oil in the oil collection tank 13 can be discharged into the oil collection box in time, and also reduce the oil retention in the oil collection tank 13, which would cause stubborn oil stains to form in the oil collection tank 13, and can also further reduce the cleaning difficulty of the casing 10.

[0102] like Figure 3 and Figure 11 As shown, according to some embodiments of this application, the third cleaning component 60 is located on the movement path of the first baffle 30, so that the third cleaning component 60 is adapted to scrape the area where the oil leakage hole 131 of the housing 10 is located under the push of the first baffle 30.

[0103] Understandably, the third cleaning component 60 is located on the movement path of the first baffle 30, enabling the third cleaning component 60 to move in conjunction with the first baffle 30. That is, the first baffle 30 can push the third cleaning component 60 to scrape the oil leakage hole 131. On the one hand, with only one driving component 70, the scraping of the side surface of the second baffle 20 facing the air intake 121, the side surface of the first baffle 30 facing the air intake 121, and the oil leakage hole 131 can be achieved simultaneously, which can simplify the structure, reduce costs, and reduce the difficulty of layout. On the other hand, the oil leakage hole 131 can also be scraped every time the range hood 100 is turned on or off, so that the oil leakage hole 131 can continuously and stably leak oil, improving the reliability and stability of the oil collection tank 13.

[0104] Of course, the linkage structure between the third cleaning component 60 and the first baffle 30 in this embodiment is not limited to this. In other embodiments, the third cleaning component 60 can be driven by the driving component 70 to move, and the first baffle 30 is located on the movement path of the third cleaning component 60 to link with the third cleaning component 60.

[0105] It should be noted that the first baffle 30 can be simultaneously formed as an oil receiving plate, and the second cleaning component 40 is set on the oil receiving plate, so that the oil scraped by the second cleaning component 40 can be collected on the oil receiving plate.

[0106] The third cleaning component 60 includes a third mounting base 61 and a third scraper 62. The third mounting base 61 is movably disposed on the housing 10, and the third scraper 62 is located on the side of the third mounting base 61 facing the oil leakage hole 131, so that the oil leakage hole 131 can be scraped by the third scraper 62.

[0107] It is understood that in some embodiments, at least one oil leakage hole 131 is provided in the oil collection tank 13, and the side of the third scraper 62 facing the oil leakage hole 131 is used to scrape the entire wall surface of the oil collection tank 13 forming the oil leakage hole 131. In other embodiments, at least one raised scraping part 621 is provided on the side of the third scraper 62 facing the oil leakage hole 131, and the raised scraping part 621 is correspondingly provided with the oil leakage hole 131 to at least scrape the area where the oil leakage hole 131 is located (see...). Figure 8 ).

[0108] Therefore, scraping the area where the oil leakage hole 131 is located can reduce the probability of the oil leakage hole 131 becoming blocked, thereby improving the reliability and stability of the oil drainage of the oil collection tank 13.

[0109] Furthermore, such as Figure 4 and Figure 5 , Figure 11 As shown, the third cleaning assembly 60 also includes a reset member 63. The first baffle 30 is adapted to push the third scraper 62. The reset member 63 is disposed between the housing 10 and the third scraper 62 and is used to provide a reset force for resetting the second scraper 42.

[0110] Specifically, the third scraper 62 can be set on the side of the third mounting base 61 facing the oil leakage hole 131, and the first baffle 30 can push the third mounting base 61 and the third scraper 62 so that the third scraper 62 moves in the oil collection groove 13 along the movement direction of the first baffle 30. During the process of the first baffle 30 pushing the third scraper 62 to move, the reset member 63 can be compressed. When the first baffle 30 is reset by the driving member 70, the reset force of the reset member 63 can drive the third scraper 62 to reset, so as to repeatedly scrape the oil leakage hole 131, improve the scraping effect, and effectively prevent the oil leakage hole 131 from becoming blocked.

[0111] It is understandable that the travel distance of the third scraper 62 is less than that of the first baffle 30. Therefore, the third scraper 62 or the third mounting base 61 should be spaced apart from the first baffle 30 in the second position. When the first baffle 30 moves from the second position to the first position, the first baffle 30 does not push against the third mounting base 61 in the initial stage. After moving for a stage, it pushes against the third mounting base 61 and scrapes the oil leakage hole 131.

[0112] Of course, there can be multiple reset pieces 63, and the multiple reset pieces 63 can be spaced apart along the length of the third mounting base 61. This can improve the force distribution of the third mounting base 61, make the movement synchronization of the third mounting base 61 better, and also improve the scraping effect of the third cleaning component 60.

[0113] Below, in conjunction with the appendix Figure 1 -Appendix Figure 8 The structure of the smoke hood 100 of the first embodiment of this application will be described in detail.

[0114] The range hood 100 includes: a housing 10 and a second cleaning assembly 40, a first cleaning assembly 50, a third cleaning assembly 60, a second baffle 20, and a first baffle 30 disposed within the housing 10.

[0115] The housing 10 includes a first plate 11 and a suction panel 12. The suction panel 12 has a suction port 121, and the first plate 11 has a discharge port 111. The discharge port 111 is located in the middle region of the first plate 11, causing the suction port 121 to be spaced apart from the projection outline of the discharge port 111 by at least part of its projection outline. A second baffle 20 is disposed on the first plate 11 and is used to at least block the area where the suction port 121 and the discharge port 111 are misaligned and opposite to the first plate 11 and the suction port 121. The first baffle 30 is located in the suction port 121. Between panel 12 and second baffle 20, a second cleaning component 40 is disposed on first baffle 30 so that it can move synchronously with first baffle 30 and scrape second baffle 20. First baffle 30 can be movably disposed in housing 10 via guide component 80. First cleaning component 50 is disposed between first baffle 30 and suction panel 12 to scrape first baffle 30. Third cleaning component 60 is disposed on the moving path of first baffle 30. At least third scraping plate 62 of third cleaning component 60 extends into oil collection tank 13 to scrape oil leakage hole 131.

[0116] Below, in conjunction with the appendix Figure 9 -Appendix Figure 11 The structure of the smoke machine 100 of the second embodiment of this application will be described in detail below.

[0117] The range hood 100 includes: a housing 10 and a first cleaning component 40, a second cleaning component 50, a third cleaning component 60, and a first baffle 30 disposed within the housing 10.

[0118] The housing 10 includes a first plate 11 and a suction panel 12. The suction panel 12 has a suction port 121, and the first plate 11 has a discharge port 111. The discharge port 111 is located in the middle region of the first plate 11, causing the projection outline of the suction port 121, at least partially facing the discharge port 111, to be spaced apart from the projection outline of the discharge port 111. This results in oil adhering to the area of ​​the first plate 11 surrounding the discharge port 111. A first baffle 30 is located between the suction panel 12 and the first plate 11. The second cleaning component 40 is disposed on the first baffle 30 so that the first baffle 30 can move synchronously and scrape the first plate 11. The first baffle 30 can be movably disposed in the housing 10 through the guide component 80. The first cleaning component 50 is disposed between the first baffle 30 and the suction panel 12 to scrape the first baffle 30. The third cleaning component 60 is disposed on the moving path of the first baffle 30. The third cleaning component 60, at least the third scraping plate 62, extends into the oil collection tank 13 to scrape the oil leakage hole 131.
