[0060] As Figure 1As shown, the oil fume treatment device 100 disclosed by the embodiment of the present disclosure comprises a main box 60, a smoke collecting cavity main body 10, a flap assembly 30 and a fan (not shown in the figure), the main box 60 comprises a main box shell 61, the main box shell 61 is in communication with the smoke collecting cavity main body 10, the fan can be in the main box shell 61 or the smoke collecting cavity main body 10, the smoke collecting cavity main body 10 has an air inlet 11, the flap assembly 30 can be switched 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, the flap assembly 30 can achieve better blocking effect for the air inlet 11, and can avoid the oil fume smell in the smoke collecting cavity main body 10 from spreading to the indoor environment; when the flap assembly 30 is in the second position, the fan works to generate negative pressure in the inside of the main box shell 61, and the oil fume outside the oil fume treatment device 100 can enter the smoke collecting cavity main body 10 and the main box 60 through the air inlet 11 and be discharged to the outdoor environment. As shown in the figure, Figure 1 As shown, the main box shell 61 is provided with an air outlet 611, and the relatively clean gas formed after the oil fume is filtered by the oil fume treatment device 100 is discharged from the air outlet 611. Among them, the smoke collecting cavity main body 10 can achieve better gathering and concentrating effect for the oil fume, which is convenient for the external oil fume to enter the rear main box 60 in large quantities and fully.

[0061] As shown, Figure 1 The flap assembly 30 comprises a first air deflector 31 and a second air deflector 32, wherein the smoke collecting cavity main body 10, the first air deflector 31 and the second air deflector 32 are rotationally connected in sequence, by adjusting the turning angle of the first air deflector 31 relative to the smoke collecting cavity main body 10 and by adjusting the turning angle of the second air deflector 32 relative to the first air deflector 31, the flap assembly 30 can be switched between different states, thereby realizing better absorption effect of the oil fume treatment device 100 for oil fume with different concentrations. Among them, when the flap assembly 30 is in the first state as shown in the figure, Figure 2 When the flap assembly 30 is in the second state as shown in the figure, Figure 3 When the flap assembly 30 is in the third state as shown in the figure, Figure 4 When the flap assembly 30 is in the third state as shown in the figure,

[0062] In an optional embodiment, as shown in the figure, Figure 2As shown, the first air deflector 31 comprises an air deflector body 311 and a baffle 312, wherein the smoke collection cavity body 10, the air deflector body 311 and the second air deflector 32 are sequentially rotationally connected, the baffle 312 is provided in two, the two baffles 312 are fixedly connected with the air deflector body 311 and are arranged in a width direction of the air deflector body 311, and the baffle 312 can realize better gathering effect on the oil fume, avoid overflow and diffusion of the oil fume, and effectively improve the oil fume suction effect of the oil fume treatment device 100.

[0063] As shown in Figures 2 to 4 The oil fume treatment device 100 further comprises an oil screen assembly 40, which is arranged at the air inlet 11, and the oil screen assembly 40 can realize preliminary filtering effect on the oil fume. The oil screen assembly 40 can be a mesh assembly, a grating flap assembly or the like, and all structures capable of realizing preliminary filtering of the oil fume are within the protection scope of the embodiments of the present disclosure.

[0064] The existing oil screen assembly 40 is mostly fixed, and the oil screen assembly 40 cannot be timely adjusted according to the dynamic change of the oil fume amount in the actual cooking process, which limits the oil screen assembly 40 to provide optimal filtering effect when facing different cooking scenes (such as a large amount of oil fume generated by fast frying with high fire or weak oil fume generated by steaming and boiling light food), thereby affecting the oil fume suction efficiency of the overall oil fume treatment device 100. The single-state oil screen assembly 40 cannot effectively match the oil fume treatment efficiency, and the oil fume suction effect and the filtering effect of the oil fume treatment device 100 cannot realize dynamic balance.

[0065] For example, in the cooking situation of high oil fume output, the static oil screen assembly 40 design is often difficult to rapidly intercept and guide a large amount of oil fume, resulting in escape of part of the oil fume and reduction of indoor air quality. On the contrary, in the case of less oil fume, the fixed oil screen assembly 40 can cause excessive filtering of the oil fume, increase unnecessary wind resistance, affect suction power, shorten the maintenance period and increase the cleaning burden of the user.

[0066] To solve the above problems, as shown in Figures 2 to 4As 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 of the fume. The drive component 50 is used to adjust the state of the flap assembly 30 and the opening of the air inlet 42 of the oil mesh assembly 40 according to the property information detected by the fume property detection component 20. The state of the flap assembly 30 and the opening of the air inlet 42 of the oil mesh assembly 40 can be dynamically and automatically adjusted according to the property information of the fume. The flap assembly 30 and the oil mesh assembly 40 can be effectively matched with the fume treatment efficiency. When facing different cooking scenarios (such as high-heat stir-frying producing a large amount of fume, or light steaming and boiling producing a small amount of fume), the fume treatment device 100 can provide the optimal fume extraction and filtration effect, ensuring that the fume treatment device 100 always maintains a good fume extraction efficiency, thereby achieving a dynamic balance between the fume extraction and filtration effects of the fume treatment device 100.

[0067] 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.

[0068] In an alternative embodiment, such as Figures 1 to 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 driving assembly 50 to work so that the flap assembly 30 is in the fourth state as shown in Figure 4 , which can achieve better oil fume suction effect for large oil fume. The temperature detection mechanism 21 can feedback the oil fume concentration at the air inlet 11 from the side, and through the setting of the temperature detection mechanism 21, the precise control of the driving assembly 50 can be achieved.

[0069] 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 检测1 of the air outlet 611, and the controller controls the driving assembly 50 to increase the opening degree of the air inlet 42 of the oil screen assembly 40. After a first preset time, the flow detection mechanism 23 obtains the second flow detection value Q 检测2 of the air outlet 611; Q 检测1 and Q 检测2 are compared: if Q 检测2 ≤Q 检测1 , it means that increasing the air inlet 42 cannot improve the air inlet amount, at this time, the opening degree of the air inlet 42 of the oil screen assembly 40 is the best opening degree under the current working condition, and the oil screen assembly 40 does not need to be adjusted; if Q 检测2 >Q 检测1 , the obtained Q 检测2 is recorded and covers the previously recorded flow data Q 检测1 , the new Q 检测1 is used as the reference data for subsequent comparison, at the same time, the controller controls the driving assembly 50 to increase the opening degree of the air inlet 42 of the oil screen assembly 40, and Q 检测2 is obtained again, and the comparison between the new Q 检测1 and the new Q 检测2 is continued until the opening degree of the air inlet 42 of the oil screen assembly 40 that is best adapted to the current working condition is found.

[0070] When T 预设2 ≤T 检测 , the flow detection mechanism 23 is used to obtain the third flow detection value Q 检测3 of the air outlet 611, and the controller controls the driving assembly 50 to increase the opening degree of the air inlet 42 of the oil screen assembly 40. After a second preset time, the flow detection mechanism 23 obtains the fourth flow detection value Q 检测4 of the air outlet 611; Q 检测3 and Q 检测4 are compared: if Q 检测4 ≤Q 检测3, it means that increasing the air inlet 42 cannot improve the air intake, at this time, the opening of the air inlet 42 of the oil screen assembly 40 is the best opening of the current working condition, and the oil screen assembly 40 does not need to be adjusted; if Q 检测4 > Q 检测3 , the obtained Q 检测4 is recorded and the previously recorded flow data Q 检测3 is overwritten, the new Q 检测3 is taken as the reference data for subsequent comparison, and at the same time, the controller controls the driving assembly 50 to increase the opening of the air inlet 42 of the oil screen assembly 40, and the Q 检测4 is obtained again, the comparison of the new Q 检测3 and the new Q 检测4 is continued, and until the opening of the air inlet 42 of the oil screen assembly 40 that is best adapted to the current working condition is found.

[0071] In an optional embodiment, as shown in Figures 1 to 4 , the temperature detection mechanism 21 can also be replaced by an oil fume concentration detection mechanism 22, which can realize more accurate detection of the oil fume concentration at the air inlet 11.

[0072] In an optional embodiment, as shown in Figures 1 to 4 , the temperature detection mechanism 21 and the oil fume concentration detection mechanism 22 can also be provided at the same time, and the controller can realize accurate fitting of the oil fume concentration at the air inlet 11 by simultaneously acquiring information of the temperature detection mechanism 21 and the oil fume concentration detection mechanism 22, thereby realizing more accurate detection of the oil fume concentration at the air inlet 11.

[0073] In an optional embodiment, as shown in Figures 2 to 4 , the driving assembly 50 includes a locking mechanism 51 and a first linear driving mechanism 52, the locking mechanism 51 is arranged between the first air deflector 31 and the smoke collecting cavity body 10, and the locking mechanism 51 can lock the first air deflector 31 and the smoke collecting cavity body 10, the first linear driving mechanism 52 includes a first driving body 521 and a first output end 522 that moves linearly relative to the first driving body 521, the first driving body 521 is rotationally connected with the smoke collecting cavity body 10, and the first output end 522 is rotationally connected with the second air deflector 32. Through the arrangement of the locking mechanism 51 and the first linear driving mechanism 52, only one set of driving mechanism can realize the time sequence opening of the first air deflector 31 and the second air deflector 32, thereby realizing the rapid switching of the flap assembly 30 between the first state, the second state and the third state, and the structure is simple and the cost is low.

[0074] 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 first state as shown in Figure 1 and Figure 2The first state is shown, at this time, the flap assembly 30 can better seal 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 first state as shown. Figure 3 The second state is shown, at this time, the first air baffle 31 seals part of the air inlet 11, and the second air baffle 32 opens part of the corresponding air inlet 11. The air inlet 11 located below can enter the oil fume, thereby meeting the better absorption effect for a small amount of oil fume. 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 second state as shown. Figure 4 The third state is shown, at this time, the first air baffle 31 and the second air baffle 32 are both flipped relative to the smoke collecting cavity main body 10, and the air inlet 11 is completely opened, thereby meeting the better absorption effect for a large amount of oil fume.

[0075] In an optional embodiment, as shown in Figures 2 to 4 The locking mechanism 51 includes a fixed seat 511 and a tension spring 512. The fixed seat 511 is arranged on the smoke collecting cavity main body 10. One end of the tension spring 512 is fixedly connected with the fixed seat 511, and the other end of the tension spring 512 is fixedly connected with the first air baffle 31. When the first output end 522 is in any state between the non-extended state and the second extended state, the forward pushing force of the second air baffle 32 on the first air baffle 31 is less than the reverse pulling force of the tension spring 512, so that the relative position of the first air baffle 31 and the smoke collecting cavity main body 10 does not change, and the first air baffle 31 can completely seal the corresponding air inlet 11. Since the locking mechanism 51 of this optional embodiment does not need to additionally increase a driving control mechanism, the overall volume of the locking mechanism 51 is smaller, the structure is simpler, and the cost is lower.

[0076] In an optional embodiment, the locking mechanism 51 is arranged on the first air baffle 31, and the smoke collecting cavity main body 10 is provided with a insertion hole (not shown in the figure). The locking mechanism 51 includes a movable part (not shown in the figure), which can be switched between a locked position of being inserted into the insertion hole and an unlocked position of being separated from the insertion hole, thereby realizing the locking and unlocking of the first air baffle 31 and the smoke collecting cavity main body 10. For example, the locking mechanism 51 can be an electromagnetic lock, which is simple in structure and easy to install.

[0077] In an optional embodiment, the locking mechanism 51 can also be arranged on the smoke collecting cavity main body 10, and the first air baffle 31 is provided with a insertion hole. The locking mechanism 51 includes a movable part, which can be switched between a locked position of being inserted into the insertion hole and an unlocked position of being separated from the insertion hole, thereby achieving the above-mentioned effect.

[0078] In an optional embodiment, as shown in Figures 2 to 4As shown, the oil net assembly 40 comprises at least two blades 41 arranged in the up-down direction (i.e. the first preset direction), and adjacent two blades 41 form a corresponding air inlet 42. The blades 41 extend along the width direction of the smoke collecting cavity body 10 (i.e. the second preset direction) and are rotationally connected with the smoke collecting cavity body 10. The driving assembly 50 can drive the at least two blades 41 to rotate synchronously. The synchronous driving of the plurality of blades 41 can be realized by only one driving assembly 50, that is, the opening degree of the plurality of air inlets 42 can also be synchronously adjusted by one driving assembly 50. The oil fume treatment device 100 has the advantages of less involved structure, compact structure, low cost, large effective smoke collecting space inside the oil fume treatment device 100, and good oil fume treatment effect of the oil fume treatment device 100. Among them, as shown in Figure 3 and Figure 4 As shown, the blade 41 comprises a blade body 411 and a rotating shaft 413 fixedly connected with the blade body 411. The rotating shaft 413 extends along the width direction of the blade body 411 and is rotationally connected with the smoke collecting cavity body 10. Through the arrangement of the rotating shaft 413, the blade 41 and the smoke collecting cavity body 10 can be rotationally connected more smoothly.
