[0002] Range hoods have become an indispensable kitchen appliance in modern homes. Their main function is to remove cooking fumes, thus maintaining a clean kitchen environment. Existing range hoods include a smoke collection chamber, a flap assembly, and an oil filter. The smoke collection chamber has an air inlet, and the flap assembly and oil filter are located at the air inlet. The flap assembly can switch between an open and closed air inlet state, and the oil filter provides initial filtration of the cooking fumes.

[0003] Most existing oil filter components are fixed and cannot be adjusted in a timely manner according to the dynamic changes in the amount of oil fumes during actual cooking. This limitation means that the oil filter components cannot provide the optimal filtration effect when facing different cooking scenarios (such as high-heat stir-frying which produces a lot of oil fumes, or light steaming and boiling which produces a little oil fumes), thus affecting the overall oil fume treatment efficiency of the device. The single-state oil filter component cannot be effectively matched with the oil fume treatment efficiency, and the oil fume treatment device cannot achieve a dynamic balance between oil fume extraction and filtration effects.

[0079] The technical solution of the present invention will be further described below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the present invention are shown in the accompanying drawings, not all of them.

[0080] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components.

Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature.

[0082] In the description of the embodiments disclosed herein, terms such as "upper," "lower," "left," and "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention. Furthermore, the terms "first" and "second" are used merely for descriptive distinction and have no special meaning.

[0083] Example 1

[0084] like Figure 1 As shown, this disclosure provides an oil fume treatment device 100. The oil fume treatment device 100 can be any type of device with oil fume treatment function, such as a top-mounted range hood, a side-suction range hood, a top-suction range hood, or a near-suction range hood. All types of devices with oil fume treatment function are within the protection scope of this disclosure. This disclosure uses a near-suction range hood as an example to describe the structure of the oil fume treatment device 100.

[0085] like Figure 1As shown in the figure, this disclosure presents an oil fume treatment device 100, which includes a main unit box 60, a smoke collection chamber body 10, a flap assembly 30, and a fan (not shown in the figure). The main unit box 60 includes a main unit box housing 61, which is connected to the smoke collection chamber body 10. The fan can be located in the main unit box housing 61 or in the smoke collection chamber body 10. The smoke collection chamber body 10 has an air inlet 11. The flap assembly 30 can switch between a first position of blocking the air inlet 11 and a second position of opening the air inlet 11. When the flap assembly 30 is in the first position, it can achieve a good blocking effect on the air inlet 11, preventing the oil fume odor in the smoke collection chamber body 10 from being transmitted into the room. When the flap assembly 30 is in the second position, the fan operates, creating a negative pressure inside the main unit box housing 61, allowing the oil fume outside the oil fume treatment device 100 to enter the smoke collection chamber body 10 and the main unit box 60 through the air inlet 11 and be discharged outdoors. Figure 1 As shown, an air outlet 611 is provided on the main unit housing 61. After the oil fumes are filtered by the oil fume treatment device 100, relatively clean gas is formed and discharged from the air outlet 611. The main body 10 of the smoke collection chamber can effectively collect and concentrate the oil fumes, so that a large amount of external oil fumes can enter the main unit housing 60 at the rear.

[0086] like Figure 1 As shown, the flap assembly 30 includes a first air guide plate 31 and a second air guide plate 32. The smoke collection chamber body 10, the first air guide plate 31, and the second air guide plate 32 are sequentially rotatably connected. By adjusting the rotation angle of the first air guide plate 31 relative to the smoke collection chamber body 10, and by adjusting the rotation angle of the second air guide plate 32 relative to the first air guide plate 31, the flap assembly 30 can switch between different states, thereby achieving a better absorption effect of the fume treatment device 100 on fumes of different concentrations. Specifically, when the flap assembly 30 is in the following state... Figure 2 In the first state shown, the flap assembly 30 can achieve a good sealing effect on the fume treatment device 100, preventing the fumes or odors inside the fume treatment device 100 from spreading out into the kitchen environment. When the flap assembly 30 is in the following state... Figure 3 In the second state shown, only part of the air inlet 11 is open, ensuring that the fume treatment device 100 absorbs a smaller amount of fume. When the flap assembly 30 is in the position shown... Figure 4 In the third state shown, the air inlet 11 is fully open, and the first air guide plate 31 and the second air guide plate 32 are fully opened to form a large area of ​​smoke collection structure, thereby ensuring that the oil fume treatment device 100 has a good absorption effect on large oil fumes.

[0087] In an alternative embodiment, such as Figure 2As shown, the first air guide plate 31 includes an air guide plate body 311 and a baffle plate 312. The smoke collection chamber body 10, the air guide plate body 311, and the second air guide plate 32 are rotatably connected in sequence. There are two baffle plates 312. The two baffle plates 312 are fixedly connected to the air guide plate body 311 and are arranged at intervals along the width direction of the air guide plate body 311. The arrangement of the baffle plates 312 can achieve a better gathering effect on the oil fumes, prevent the oil fumes from overflowing and spreading, and effectively improve the oil fume absorption effect of the oil fume treatment device 100.

[0088] like Figures 2-4 As shown, the fume treatment device 100 also includes an oil mesh assembly 40, which is disposed at the air inlet 11. The oil mesh assembly 40 can achieve a preliminary filtration effect on the oil fumes. The oil mesh assembly 40 can be a mesh assembly, a grille flap assembly, etc., and all structures capable of achieving preliminary filtration of oil fumes are within the protection scope of this disclosure embodiment.

[0089] Most existing oil filter components 40 are fixed and cannot be adjusted in a timely manner according to the dynamic changes in the amount of oil fumes during actual cooking. This limitation means that the oil filter component 40 cannot provide the optimal filtration effect when facing different cooking scenarios (such as high-heat stir-frying producing a large amount of oil fumes, or light steaming and boiling producing a small amount of oil fumes), thus affecting the overall oil fume treatment device 100's oil fume extraction efficiency. The single-state oil filter component 40 cannot be effectively matched with the oil fume treatment efficiency, and the oil fume extraction effect and filtration effect of the oil fume treatment device 100 cannot achieve a dynamic balance.

[0090] For example, in cooking scenarios with high levels of oil fumes, a static oil filter assembly 40 design often struggles to quickly intercept and guide large amounts of oil fumes, causing some fumes to escape and reducing indoor air quality. Conversely, in situations with less oil fumes, a fixed oil filter assembly 40 may cause over-filtration of oil fumes, increasing unnecessary wind resistance, affecting suction power, shortening maintenance cycles, and increasing the user's cleaning burden.

[0091] To solve the above problems, such as Figures 2-4 As shown, the fume treatment device 100 also includes a fume property detection component 20 and a drive component 50. The fume property detection component 20 is used to detect the property information P of the fume. 检测 The drive component 50 is used to detect the value P based on the physical property information detected by the oil fume physical property detection component 20. 检测 The state of the flap assembly 30 and the opening of the air inlet 42 of the oil mesh assembly 40 are adjusted according to the detection value P of the physical property information of the oil fume. 检测By achieving dynamic and automated adjustment, the flap assembly 30 and the oil mesh assembly 40 can be effectively matched with the oil fume treatment efficiency. When facing different cooking scenarios (such as high-heat stir-frying producing a large amount of oil fumes, or light steaming and boiling producing a small amount of oil fumes), the oil fume treatment device 100 can provide the optimal oil fume extraction and filtration effects, ensuring that the oil fume treatment device 100 always maintains good oil fume extraction efficiency, thereby achieving a dynamic balance between the oil fume extraction and filtration effects of the oil fume treatment device 100.

[0092] Furthermore, the drive component 50 can adjust its power according to the actual situation of cooking fumes, avoiding unnecessary power consumption, thereby achieving the goal of energy saving and emission reduction, which is in line with the development trend of modern green home appliances. In addition, the fume treatment device 100 can better adapt to the cooking habits and kitchen environment of different users, effectively improving the user experience and enhancing the product's market competitiveness and applicability.

[0093] In an alternative embodiment, such as Figures 1-4 As shown, the fume treatment device 100 also includes a controller, and the fume property detection component 20 includes a temperature detection mechanism 21 and a flow detection mechanism 23. The temperature detection mechanism 21 and the flow detection mechanism 23 are respectively communicatively connected to the controller. The temperature detection mechanism 21 is located at the air inlet 11, and the flow detection mechanism 23 is located at the air outlet 611 of the fume treatment device 100. The temperature detection mechanism 21 is used to obtain the temperature value T at the air inlet 11. 检测 The controller will T 检测 Each is compared with the first preset temperature value T 预设1 and the second temperature preset value T 预设2 Comparison, where T 预设1 <T 预设2 When T 检测 <T 预设1 The controller controls the drive component 50 to operate so that the flap component 30 is in the position as follows: Figure 1 and Figure 2 The first state shown; when T 预设1 ≤T 检测 <T 预设2 The controller controls the drive component 50 to operate so that the flap component 30 is in the position as follows: Figure 3 The second state shown can achieve a good smoke extraction effect for smaller amounts of oil fumes; when T 预设2 ≤T 检测 The controller controls the drive component 50 to operate so that the flap component 30 is in the position as follows: Figure 4 The third state shown can achieve a better oil fume extraction effect for larger amounts of oil fumes. The temperature detection mechanism 21 can provide feedback on the oil fume concentration at the air inlet 11 from the side. By setting the temperature detection mechanism 21, precise control of the drive component 50 can be achieved.

[0094] When T 预设1 ≤T 检测 <T 预设2 The flow detection mechanism 23 is used to obtain the first flow detection value Q of the air outlet 611. 检测1 The controller controls the drive assembly 50 to increase the opening of the air inlet 42 of the oil mesh assembly 40. After a first preset time, the flow detection mechanism 23 obtains the second flow detection value Q of the air outlet 611. 检测2 Q 检测1 With Q 检测2 Comparison: If Q 检测2 ≤Q 检测1 This means that increasing the air inlet 42 will not increase the air intake volume. In this case, the opening of the air inlet 42 of the oil filter assembly 40 is the optimal opening under this operating condition, and the oil filter assembly 40 does not need to be adjusted; if Q 检测2 >Q 检测1 Then the obtained Q 检测2 Record and overwrite previously recorded traffic data Q 检测1 The new Q 检测1 As the baseline data for subsequent comparisons, the controller control drive component 50 simultaneously increases the opening of the air inlet 42 of the oil mesh component 40 to obtain Q again. 检测2 Continue with the new Q 检测1 With the new Q 检测2 The comparison continues until the optimal opening degree of the air inlet 42 of the oil mesh assembly 40 is found to suit the current operating conditions.

[0095] When T 预设2 ≤T 检测 The flow detection mechanism 23 is used to obtain the third flow detection value Q of the air outlet 611. 检测3 The controller controls the drive assembly 50 to increase the opening of the air inlet 42 of the oil mesh assembly 40. After a second preset time, the flow detection mechanism 23 obtains the fourth flow detection value Q of the air outlet 611. 检测4 Q 检测3 With Q 检测4 Comparison: If Q 检测4 ≤Q 检测3 This means that increasing the air inlet 42 will not increase the air intake volume. In this case, the opening of the air inlet 42 of the oil filter assembly 40 is the optimal opening under this operating condition, and the oil filter assembly 40 does not need to be adjusted; if Q 检测4 >Q 检测3 Then the obtained Q 检测4 Record and overwrite previously recorded traffic data Q 检测3 The new Q 检测3 As the baseline data for subsequent comparisons, the controller control drive component 50 simultaneously increases the opening of the air inlet 42 of the oil mesh component 40 to obtain Q again.检测4 Continue with the new Q 检测3 With the new Q 检测4 The comparison continues until the optimal opening degree of the air inlet 42 of the oil mesh assembly 40 is found to suit the current operating conditions.

[0096] In an alternative embodiment, such as Figures 1-4 As shown, the temperature detection mechanism 21 can also be replaced by the oil fume concentration detection mechanism 22, which can achieve more accurate detection of the oil fume concentration at the air inlet 11.

[0097] In an alternative embodiment, such as Figures 1-4 As shown, a temperature detection mechanism 21 and an oil fume concentration detection mechanism 22 can also be set at the same time. By acquiring information from both the temperature detection mechanism 21 and the oil fume concentration detection mechanism 22 at the same time, the controller can achieve accurate fitting of the oil fume concentration at the air inlet 11, thereby enabling more accurate detection of the oil fume concentration at the air inlet 11.

[0098] In an alternative embodiment, such as Figures 2-4 As shown, the drive assembly 50 includes a locking mechanism 51 and a first linear drive mechanism 52. The locking mechanism 51 is disposed between the first air guide plate 31 and the smoke collection chamber body 10, and can lock the first air guide plate 31 and the smoke collection chamber body 10. The first linear drive mechanism 52 includes a first drive body 521 and a first output end 522 that moves linearly relative to it. The first drive body 521 is rotatably connected to the smoke collection chamber body 10, and the first output end 522 is rotatably connected to the second air guide plate 32. With the setting of the locking mechanism 51 and the first linear drive mechanism 52, the sequential opening of the first air guide plate 31 and the second air guide plate 32 can be realized using only one drive mechanism, thereby realizing the rapid switching of the flap assembly 30 between the first state, the second state, and the third state. The structure is simple and the cost is low.

[0099] Specifically, when the first output end 522 is in the retracted state and the locking mechanism 51 is in the locked state, the flap assembly 30 is in the following position: Figure 1 and Figure 2 In the first state shown, the flap assembly 30 can effectively block the air inlet 11. When the first output end 522 is in the first extended state and the locking mechanism 51 is in the locked state, the flap assembly 30 is in the following state: Figure 3 In the second state shown, the first air guide plate 31 blocks part of the air inlet 11, while the second air guide plate 32 partially opens the corresponding air inlet 11, allowing the lower air inlet 11 to enter and thus achieving a good absorption effect for a small amount of oil fumes. When the first output end 522 is in the second extended state and the locking mechanism 51 is in the unlocked state, the flap assembly 30 is in the position shown. Figure 4 In the third state shown, both the first air guide plate 31 and the second air guide plate 32 are flipped relative to the main body 10 of the smoke collection chamber, and the air inlet 11 is fully opened, thereby achieving a better absorption effect for a large amount of oil fumes.

[0100] In an alternative embodiment, such as Figures 2-4 As shown, the locking mechanism 51 includes a fixed base 511 and a tension spring 512. The fixed base 511 is disposed on the smoke collection chamber body 10. One end of the tension spring 512 is fixedly connected to the fixed base 511, and the other end of the tension spring 512 is fixedly connected to the first air guide plate 31. When the first output end 522 is in any state between the non-extended state and the second extended state, the forward thrust exerted by the second air guide plate 32 on the first air guide plate 31 is less than the reverse tension of the tension spring 512. Therefore, the relative position of the first air guide plate 31 and the smoke collection chamber body 10 does not change, and the first air guide plate 31 can completely block the corresponding air inlet 11. Since the locking mechanism 51 of this optional embodiment does not require an additional drive control mechanism, the overall size of the locking mechanism 51 is smaller, the structure is simpler, and the cost is lower.

[0101] In an optional embodiment, a locking mechanism 51 is disposed on the first air guide plate 31. The smoke collection chamber body 10 has an insertion hole (not shown in the figure). The locking mechanism 51 includes a movable part (not shown in the figure) that can switch between a locked position inserted into the insertion hole and an unlocked position disengaged from the insertion hole, thereby achieving locking and unlocking of the first air guide plate 31 and the smoke collection chamber body 10. For example, the locking mechanism 51 can be an electromagnetic lock, which has a simple structure and is easy to install.

[0102] In an optional embodiment, the locking mechanism 51 can also be disposed on the smoke collection chamber body 10, and the first air guide plate 31 is provided with an insertion hole. The locking mechanism 51 includes a movable part, which can switch between a locked position inserted into the insertion hole and an unlocked position disengaged from the insertion hole, thus achieving the above-mentioned effect.

[0103] In an alternative embodiment, such as Figures 2-4 As shown, the oil mesh assembly 40 includes at least two fan blades 41, which are arranged in a vertical direction (i.e., a first preset direction). Adjacent fan blades 41 form corresponding air inlets 42. The fan blades 41 extend along the width direction of the smoke collection chamber body 10 (i.e., a second preset direction) and are rotatably connected to the smoke collection chamber body 10. The drive assembly 50 can drive at least two fan blades 41 to rotate synchronously. Multiple fan blades 41 can be synchronously driven by only one drive assembly 50. In other words, the opening of multiple air inlets 42 can also be synchronously adjusted by one drive assembly 50. The oil fume treatment device 100 involves fewer structures, has a compact structure, low cost, a large effective smoke collection space inside the oil fume treatment device 100, and good oil fume extraction effect. For example, Figure 3and Figure 4 As shown, the fan blade 41 includes a fan blade body 411 and a rotating shaft 413 fixedly connected thereto. The rotating shaft 413 extends along the width direction of the fan blade body 411 and is rotatably connected to the smoke collection chamber body 10. Through the setting of the rotating shaft 413, the fan blade 41 and the smoke collection chamber body 10 can achieve a smoother rotational connection.

[0104] In an alternative embodiment, such as Figures 3-5 As shown, the drive assembly 50 includes a rotary drive mechanism 53, a transmission component 54, and a connecting rod 55. The rotary drive mechanism 53 includes a second drive body 531 and a second output end 532 that rotates relative to it in the width direction of the smoke collection chamber body 10. The second drive body 531 is disposed on the smoke collection chamber body 10. The transmission component 54 is fixedly connected to the second output end 532 and has a slide groove 541. The connecting rod 55 includes a connecting rod body 551 and a guide component 552 disposed thereon. The guide component 552 is inserted into the slide groove 541 and slides along the slide groove 541. The fan blade 41 is rotatably connected to the connecting rod body 551. The fan blade 41 can rotate relative to the connecting rod body 551 in the width direction of the smoke collection chamber body 10. When the second output end 532 rotates clockwise, it drives the transmission component 54 to move clockwise, which in turn drives the guide component 552 to move in the slide groove 541. This causes the connecting rod body 551 to move, driving the fan blade 41 to rotate around the width of the smoke collection chamber body 10, thereby increasing the opening of the air inlet 42. When the second output end 532 rotates counterclockwise, the relevant components move in the opposite direction, thereby decreasing the opening of the air inlet 42.

[0105] In an alternative embodiment, such as Figure 5 As shown, the fan blade 41 also includes a connecting shaft 412. One end of the connecting shaft 412 is fixedly connected to the rotating shaft 413, and the other end of the connecting shaft 412 is fixedly connected to the connecting rod body 551. Through the setting of the connecting shaft 412, a stable connection between the fan blade 41 and the connecting rod body 551 can be achieved.

[0106] In an alternative embodiment, such as Figures 4-6As shown, the guide member 552 includes a guide portion 5521 and a limiting portion 5522. One end of the guide portion 5521 is fixedly connected to the connecting rod body 551, and the other end of the guide portion 5521 is fixedly connected to the limiting portion 5522. The limiting portion 5522 and the connecting rod body 551 are located on both sides of the transmission member 54. By setting the limiting portion 5522, the guide member 552 can be prevented from disengaging from the slide groove 541, achieving a better limiting effect on the guide member 552 and ensuring that the guide member 552 always slides smoothly in the slide groove 541. In an optional embodiment, the guide member 552 may also include a rotating member (not shown in the figure). The inner ring of the rotating member is sleeved on the outer periphery of the guide portion 5521. The rotating member can rotate relative to the guide portion 5521. The outer peripheral surface of the rotating member abuts against the inner wall of the slide groove 541 and can slide along the inner peripheral surface of the slide groove 541. By setting the rotating member, the smooth sliding of the guide member 552 in the slide groove 541 can be ensured. For example, the rotating component can be a bearing, a rotating wheel, etc.

[0107] In an alternative embodiment, such as Figure 6 and Figure 7 As shown, the transmission component 54 has a mounting hole 542, and the second output end 532 is inserted into the mounting hole 542. The mounting hole 542 is non-circular. By setting the mounting hole 542 as non-circular, the rotation of the second output end 532 relative to the transmission component 54 can be avoided to the greatest extent, thus achieving a stable connection between the second output end 532 and the transmission component 54. For example, the mounting hole 542 can be triangular, elliptical, rectangular, etc., and all non-circular structures are within the protection scope of this optional embodiment.

[0108] Example 2

[0109] like Figures 8-10As shown, this embodiment of the present disclosure provides 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 1. The main difference between the two is that the structure of the drive assembly 50 is different. The fan blade 41 includes a fan blade body 411 and a rotating shaft 413. The rotating shaft 413 is rotatably connected to the smoke collection chamber body 10. The drive assembly 50 includes a gear 56, a rack 57 and a second linear drive mechanism 58. The rotating shaft 413 is fixedly connected to the gear 56. The rack 57 is disposed on one side of the gear 56 and meshes with the gear 56. The second linear drive mechanism 58 includes a third drive body 581 and a third output end 582 that can move linearly in the up and down direction relative to it. The third output end 582 is fixedly connected to the rack 57. When the third output terminal 582 moves vertically, it drives the rack 57 to move vertically as well. The rack 57 drives the gear 56, the rotating shaft 413, and the fan blade body 411 to rotate around the axis of the rotating shaft 413, thereby achieving rapid adjustment of the opening of the air inlet 42. The cooperation between the gear 56 and the rack 57 can meet the requirements of heavy load, high precision, high rigidity, high speed, and long stroke, and can achieve precise adjustment of the opening of the air inlet 42. In addition, the drive assembly 50 of this embodiment has a simple structure and a long service life.

[0110] In an alternative embodiment, such as Figure 9 As shown, the drive assembly 50 also includes a guide rail 59, which is disposed on the main body 10 of the smoke collection chamber and extends in the vertical direction. A guide block (not shown in the figure) is provided on the rack 57. The guide block can slide along the guide rail 59. The guide block and the guide rail 59 cooperate to achieve the guiding effect of the rack 57 moving in the vertical direction, ensuring that the rack 57 always moves well in the vertical direction, avoiding the rack 57 from deflecting during the movement, and ensuring the precise adjustment of the opening degree of the air inlet 42 by the drive assembly 50.

[0111] Example 3

[0112] This disclosure provides a control method for controlling the oil fume treatment device 100 of Embodiment 1 or Embodiment 2, such as... Figure 11 As shown, the control method includes:

[0116] Furthermore, by applying the control method of this disclosure embodiment, the power of the fume treatment device 100 can be adjusted according to the actual situation of the oil fume, avoiding ineffective power consumption, thereby achieving the purpose of energy saving and emission reduction, which is in line with the development trend of modern green home appliances.

The controller can control and adjust the state of the flap assembly 30 and the opening of the air inlet 42 of the oil mesh assembly 40 according to different oil fume conditions, thereby achieving a precise match between the state of the flap assembly 30 and the opening of the air inlet 42 of the oil mesh assembly 40 and the current oil fume situation. This makes the adjustment of the oil fume treatment device 100 more accurate in matching different oil fume conditions, and the oil fume treatment device 100 can achieve a better absorption effect on oil fumes under different oil fume conditions.

[0118] In an optional embodiment, the physical property information detection value P 检测 It can also include only the inlet air property information detection value P 进风口检测 and the detected value P of the air quality information 出风检测 One of them, thereby realizing the state of the corresponding flap assembly 30 and the opening degree of the air inlet 42 of the oil mesh assembly 40 with the current oil fume situation, so that the adjustment of the oil fume treatment device 100 can match different oil fume situations more quickly, and the oil fume treatment device 100 can achieve a better absorption effect on oil fumes under different oil fume conditions.

[0119] In an optional embodiment, the inlet property information detection value P 进风口检测This includes at least one of the following: oil fume concentration, oil fume temperature, oil fume velocity, and oil fume flow rate. A higher oil fume concentration, oil fume velocity, oil fume flow rate, and oil fume temperature indicate a higher oil fume concentration. It should be noted that all physical property parameters reflecting oil fume conditions are within the protection scope of this disclosure's embodiments.

[0120] It should be noted that this can be achieved through methods such as Figure 1 The oil fume property detection component 20 shown is used to obtain the inlet air property information detection value P. 进风口检测 The oil fume property detection component 20 can be an oil fume concentration detection mechanism 22, an oil fume flow rate detection mechanism, a flow rate detection mechanism 23, a temperature detection mechanism 21, etc. Since the aforementioned mechanisms are common structures in the field, the specific structures corresponding to the aforementioned mechanisms will not be described in detail in this embodiment. All types of smoke concentration detection mechanisms, oil fume flow rate detection mechanisms, oil fume flow rate detection mechanisms, and temperature detection mechanisms are within the protection scope of this embodiment.

[0121] In an optional embodiment, the air outlet property information detection value P 出风检测 This includes at least one of the following: oil fume concentration, oil fume temperature, oil fume velocity, and oil fume flow rate. A higher oil fume concentration, oil fume velocity, oil fume flow rate, and oil fume temperature indicate a higher oil fume concentration. It should be noted that all physical property parameters reflecting oil fume conditions are within the protection scope of this disclosure's embodiments.

[0122] It should be noted that this can be achieved through methods such as Figure 1 The oil fume property detection component 20 shown is used to obtain the exhaust air property information detection value P. 出风检测 The oil fume property detection component 20 can be an oil fume concentration detection mechanism 22, an oil fume flow rate detection mechanism, a flow rate detection mechanism 23, a temperature detection mechanism 21, etc. Since the aforementioned mechanisms are common structures in the field, the specific structures corresponding to the aforementioned mechanisms will not be described in detail in this embodiment.

[0123] Example 4

[0124] This disclosure provides a control method for controlling the oil fume treatment device 100 of Embodiment 1 or Embodiment 2, such as... Figure 12 As shown, this control method is a further refinement of the control method in Embodiment 3, and the control method includes:

[0126] S12: Based on the detected value P from the air inlet's physical property information.进风口检测 Adjust the status of the flip panel component 30;

[0127] S21: Obtain the detection value P of the physical property information of the oil fume at the outlet 611 of the oil fume treatment device. 出风检测 ;

[0128] S22: Based on the detected value P of the air outlet material property information 出风检测 Adjust the opening of the air inlet 42 of the oil mesh assembly 40.

[0129] The step of adjusting the state of the flap assembly 30 precedes the step of adjusting the opening of the air inlet 42 of the oil mesh assembly 40.

[0130] like Figures 2-4 As shown, since the flap assembly 30 is closest to the area with the highest concentration of oily fumes, adjusting the state of the flap assembly 30 has a significant impact on oily fume absorption, accounting for 80% of the effect. Therefore, adjusting the state of the flap assembly 30 first allows for a quick and preliminary coarse adjustment of the oily fume treatment device 100. Adjusting the opening of the air inlet 42 of the oil mesh assembly 40 has a relatively weaker impact on oily fume absorption. However, adjusting the opening of the air inlet 42 of the oil mesh assembly 40 allows for further fine-tuning of oily fume absorption, achieving better absorption of oily fumes under specific oily fume conditions. In summary, through the aforementioned sequential adjustment method, the oily fume treatment device 100 can be quickly and accurately adjusted, thereby achieving better absorption of oily fumes under different oily fume conditions.

[0131] Example 5

[0132] This disclosure provides a control method for controlling the oil fume treatment device 100 of Embodiment 1 or Embodiment 2. This control method is a further refinement of the control method of Embodiment 3, such as... Figure 13 As shown, the control method includes:

[0133] S10: Start the fume treatment device 100;

[0134] S11: Obtain the air inlet physical property information detection value P 进风口检测 ;

[0135] S121: The inlet air property information detection value P 进风口检测 Each is compared with the first preset value P of physical property information 预设1 and the first physical property information preset value P 预设2 Comparison, where P 预设1 <P 预设2 If P 进风口检测 <P 预设1If P 预设1 ≤P 进风口检测 <P 预设2 If P 预设2 ≤P 进风口检测 Then proceed to S124.

[0137] S123: Adjust the flap assembly 30 to the half-open position;

[0138] S124: Adjust the flap assembly 30 to the fully open position.

[0140] Example 6

[0141] This disclosure provides a control method for controlling the oil fume treatment device 100 of Embodiment 1 or Embodiment 2. This control method is a further refinement of the control method of Embodiment 3, such as... Figure 14 As shown, the control method includes:

[0147] If P 出风检测2 ≤P 出风检测1 Then proceed to S223;

[0148] S223: Control the air intake 42 to maintain its current opening.

[0149] If P 出风检测2 ≤P 出风检测1 This means that increasing the opening of the air inlet 42 will not increase the air intake volume. In this case, the opening of the air inlet 42 of the oil filter assembly 40 is the optimal opening under this operating condition and no adjustment is needed; if P 出风检测2 >P 出风检测1 Then the obtained P 出风检测2 Record and overwrite the previously recorded P 出风检测1 P serves as the benchmark data for subsequent comparisons. 出风检测1 Simultaneously, the oil filter assembly 40 is adjusted to further increase the opening of the air intake 42, thereby regaining P. 出风检测2 Continue with step S222 as described above until the optimal opening degree of the air intake 42 suitable for the current operating conditions is found. Through the control method of this embodiment, rapid adjustment of the optimal opening degree of the air intake 42 for different operating conditions can be achieved.
