Description

Technical Field

[0001] The present invention relates to the technical field of household appliances, and in particular to an oil fume treatment device and a control method therefor. Background Art

[0002] As an essential device in the kitchen, the main function of an oil fume extractor is to effectively suck away the oil fume generated during cooking, so as to keep the indoor air fresh and reduce the pollution of the walls, furniture, etc. by the oil fume.

[0003] Currently, the oil fume extractors on the market generally adopt a single air inlet design. With the diversification of cooking methods, especially in home cooking, the heights, calibers, shapes, etc. of different types of cookware vary to different degrees. For example, high pots, flat pans, deep pots, large-caliber cookware, small-caliber cookware, etc. Different types of cookware result in significant differences in the area range and height where the oil fume is generated. The single air inlet design cannot flexibly cope with different cookware situations, often causing the oil fume to accumulate in local areas, affecting the air quality, and even potentially harming the health of the cook.

[0004] In addition, many oil fume extractors only achieve the capture of oil fume in different states by adjusting the wind speed. Inevitably, at a lower wind speed, the smoking effect is poor, while at a higher wind speed, it leads to greater noise and energy consumption, and it is difficult to achieve good capture of oil fume in different areas all the time, adapt the oil fume suction to different states of oil fume, use at low noise, and use with low energy consumption.

[0104] Embodiment 1

[0105] As Figures 1 - 2 shown, the embodiments of the present disclosure provide an oil fume treatment device 100. The oil fume treatment device 100 includes a main chassis (not shown in the figure) and a smoke collecting cavity assembly that are connected and communicated. Among them, a fan is provided in the main chassis, and the smoke collecting cavity assembly has an air inlet. When the main chassis works, the oil fume outside the oil fume treatment device 100 can enter from the air inlet. The oil fume sequentially passes through the smoke collecting cavity assembly and the main chassis, and the oil fume is purified in the main chassis. The purified gas is discharged from the air outlet (not shown in the figure) of the main chassis to an external pipeline or the indoor.

[0106] As Figure 1 and Figure 2As shown in the figure, the smoke collection chamber assembly includes a housing 20, a flap mechanism 30, and a drive assembly 10. Among them, the flap mechanism 30 can rotate relative to the housing 20, and the drive assembly 10 can drive the flap mechanism 30 to switch between an open position and a closed position. When the flap mechanism 30 is in the open position, the flap mechanism 30 can achieve a better gathering effect on the oil fume, and the flap mechanism 30 can guide a large amount of oil fume to enter the main chassis better.

[0107] Currently, the oil fume treatment devices 100 on the market generally adopt a single air inlet design. With the diversification of cooking methods, especially in home cooking, the heights, calibers, shapes, etc. of different types of cookware 200 vary to different degrees. For example, high pots, flat pans, deep pots, large-caliber cookware 200, small-caliber cookware 200, etc. Different types of cookware 200 result in significant differences in the area range and height where the oil fume is generated. The single air inlet design cannot flexibly handle different cookware 200 situations, often causing the oil fume to accumulate in local areas, affecting the air quality, and even potentially harming the health of the cook.

[0108] In addition, many oil fume treatment devices 100 only achieve the capture of oil fume in different states by adjusting the wind speed. Inevitably, at a lower wind speed, the smoking effect is poor, while at a higher wind speed, it leads to greater noise and energy consumption, and it is difficult to achieve the simultaneous consideration of always better capturing the oil fume in different areas, adapting the oil fume suction to different states of oil fume, using at low noise, and using at low energy consumption.

[0109] To solve the above problems, as Figure 1 and Figure 2 shown, a first air inlet 21 and a second air inlet 22 are provided on the housing 20. Among them, the first air inlet 21 and the second air inlet 22 are arranged in the vertical direction. The flap mechanism 30 can cover the first air inlet 21. The oil fume treatment device 100 further includes a movable mechanism 40 and a control mechanism 50. The movable mechanism 40 can cover at least part of the second air inlet 22. The control mechanism 50 can obtain the vertical distances between the first air inlet 21 and the second air inlet 22 and the pot mouth 210 of the cookware 200 respectively, as well as the oil fume physical property information P. The drive assembly 10 can, according to the vertical distances between the first air inlet 21 and the second air inlet 22 and the pot mouth 210 of the cookware 200 respectively, and the oil fume physical property information P obtained by the control mechanism 50, the two types of parameters act synergistically to comprehensively and adaptively adjust the positions and postures of the flap mechanism 30 and the movable mechanism 40, so that the oil fume treatment device 100 can be in different working modes, and can achieve better absorption of the oil fume generated in different areas and at different heights by different types of cookware 200, avoid the accumulation of oil fume in local areas, ensure good air quality, and ensure the health of the user.

[0110] In addition, the oil fume treatment device 100 according to the embodiments of the present disclosure synergistically adjusts the positions and postures of the flap mechanism 30 and the movable mechanism 40 through two types of parameters to comprehensively and adaptively adjust the oil fume treatment device 100 to different working modes, without using the prior art method of adjusting the wind speed to capture oil fumes in different states. Therefore, problems such as poor smoking effect caused by changes in wind speed, as well as large noise and high energy consumption caused by changes in wind speed, can be avoided. Therefore, by using the oil fume treatment device 100 according to the embodiments of the present disclosure, it is possible to always capture oil fumes in different areas well, adapt the oil fume suction force to oil fumes in different states, use the device at low noise, and use it with low energy consumption, achieving a dynamic balance of better absorption of oil fumes in different forms, better oil fume suction force, low noise use of the oil fume treatment device 100, and low energy consumption use, and realizing the optimal use performance of the oil fume treatment device 100.

[0111] Specifically, as Figures 1 - 16 shown, the driving component 10 can adjust the flap mechanism 30 and / or the movable mechanism 40 to open the second air inlet 22 or the first air inlet 21 closest to the pot opening 210 of the cookware 200. The state of the second air inlet 22 or the first air inlet 21 can be adjusted according to the height of different cookware 200, so as to ensure that the smoke inlet path is the shortest path, thereby improving the smoking effect and achieving better absorption of the oil fumes generated by cookware 200 of different heights. In addition, the driving component 10 can also adjust the opening angle of the flap mechanism 30 according to the detected oil fume physical property information P, so as to further improve the smoking effect for the oil fume area ranges generated by different types of cookware 200. In summary, the oil fume treatment device 100 according to the embodiments of the present disclosure can flexibly respond to the oil fume conditions generated by different cookware 200, avoid the accumulation of oil fumes in local areas, ensure good air quality, and ensure the physical health of the users.

[0112] In an alternative embodiment, as Figures 1 - 16 shown, the height of the cookware 200 has the greatest influence on the oil fume formation area, and the shape and caliber of the cookware 200 will also have a certain influence on the oil fume formation area, but the influence is slightly weaker. Therefore, first adjusting the selection of the first air inlet 21 or the second air inlet 22 according to the height of the cookware 200 can achieve a quick and main adjustment of the oil fume treatment device 100. Then, continuing to make more refined adjustments to the oil fume treatment device 100 according to the secondary influencing parameters can achieve a better absorption effect for the oil fume areas formed by different cookware. In summary, through the sequential adjustment of the above two aspects, a quick and accurate adjustment of the oil fume treatment device 100 can be achieved.

[0113] In an alternative embodiment, as Figure 1 and Figure 17As shown, the fume treatment device 100 further includes a detection component 80. Among them, the detection component 80 includes a cookware physical property detection mechanism 81. The cookware physical property detection mechanism 81 is communicatively connected to the control mechanism 50. The cookware physical property detection mechanism 81 can detect the physical property information of the cookware 200. The control mechanism 50 can obtain the vertical distances between the first air inlet 21 and the second air inlet 22 and the pot opening 210 of the cookware 200 respectively according to the physical property information of the cookware 200. Thus, the control mechanism 50 can determine which air inlet is the closest to the pot opening 210. Exemplarily, the cookware physical property detection mechanism 81 can be an ultrasonic distance detection mechanism, a laser distance detection mechanism, an image forming mechanism, etc. All cookware physical property detection mechanisms 81 that can directly or indirectly obtain the vertical distances between the first air inlet 21 and the second air inlet 22 and the pot opening 210 of the cookware 200 are within the protection scope of the embodiments of the present disclosure.

[0114] In an alternative embodiment, as Figure 1 and Figure 17 shown, the detection component 80 further includes a fume physical property detection mechanism 82. The fume physical property detection mechanism 82 is communicatively connected to the control mechanism 50. The fume physical property detection mechanism 82 can detect the physical property information of the fume. The control mechanism 50 can obtain the diffusion and overflow conditions of the fume according to the physical property information of the fume detected by the fume physical property detection mechanism 82, and can achieve precise adjustment of the flap mechanism 30 for the diffusion and overflow conditions of the fume.

[0115] Exemplarily, the physical property information of the fume can be fume concentration information, fume flow velocity information, fume pressure information, fume temperature information, etc. All physical property information of the fume that can directly or indirectly reflect the diffusion and overflow conditions of the fume are within the protection scope of the embodiments of the present disclosure. Exemplarily, the fume physical property detection mechanism 82 can be a fume concentration detection mechanism, a fume flow velocity detection mechanism, a fume pressure detection mechanism, a fume temperature detection mechanism, a thermal imaging mechanism, etc.

[0116] In an alternative embodiment, the fume physical property detection mechanism 82 can be arranged on the outer surface of the flap mechanism 30, which can better detect the escape condition of the fume.

[0117] In an alternative embodiment, as Figure 1 shown, the fume physical property detection mechanism 82 can be arranged at the lower end of the flap mechanism 30, which can quickly obtain and feedback the escape condition of the fume in the first time.

[0118] In an alternative embodiment, as Figures 1 - 16As shown, the second air inlet 22 includes at least two groups of air inlet mesh openings. The at least two groups of air inlet mesh openings are arranged at intervals in the vertical direction. By setting a relatively large number of air inlet mesh openings with different heights, the second air inlet 22 can be adapted to cookware 200 of more different heights. The oil fume treatment device 100 has a higher precision in adapting to cookware 200 of different heights, and can better meet the different needs of users.

[0119] Exemplarily, the driving assembly 10 includes a first driving mechanism 11 and a second driving mechanism 12. The first driving mechanism 11 and the second driving mechanism 12 are respectively communicatively connected to the control mechanism 50. The first driving mechanism 11 cooperates with the second driving mechanism 12 to adjust the flap mechanism 30 and / or the movable mechanism 40, so that the one of the air inlet mesh opening and the first air inlet 21 that is closest to the pot opening 210 of the cookware 200 is in an open state, and can also adjust the opening angle of the flap mechanism 30 according to the detected oil fume physical property information P. Through the settings of the first driving mechanism 11 and the second driving mechanism 12, independent and flexible adjustment of the flap mechanism 30 and the movable mechanism 40 can be achieved, so as to achieve flexible adjustment of the oil fume treatment device 100 in different states.

[0120] In an optional embodiment, as Figure 1 and Figure 2 shown, the second air inlet 22 includes a lower air inlet mesh opening 222. The movable mechanism 40 has a first position. The first driving mechanism 11 can drive the movable mechanism 40 to be in the first position. When the movable mechanism 40 is in the first position, the movable mechanism 40 opens the lower air inlet mesh opening 222 and blocks the middle air inlet mesh opening 221. In this state, the oil fume treatment device 100 can have a good absorption effect on the oil fume generated by cookware of lower and medium heights, such as a flat-bottomed frying pan, a baking tray, etc.

[0121] As Figure 3 and Figure 4 shown, after the cookware 200 has been cooking for a period of time, there may be a problem that the oil fume absorption effect of a single second air inlet 22 is insufficient, resulting in the diffusion and overflow of oil fume. When the physical property information of the oil fume detected by the oil fume physical property detection mechanism 82 exceeds the threshold, the control mechanism 50 controls the second driving mechanism 12 to act, so that the flap mechanism 30 opens. The flap mechanism 30 can achieve a good oil fume gathering effect, so as to achieve a good oil fume absorption effect of the oil fume treatment device 100.

[0122] It should be noted that the opening angle of the flap mechanism 30 can increase with the increase of the oil fume physical property information P detected by the oil fume physical property detection mechanism 82, so as to achieve the matching degree of the opening angle of the flap mechanism 30 with different oil fume conditions.

[0123] In an optional embodiment, as Figure 5 and Figure 6As shown, the second air inlet 22 further includes a middle air inlet mesh opening 221. Among them, the middle air inlet mesh opening 221 and the lower air inlet mesh opening 222 are arranged from top to bottom. The moving mechanism 40 further has a second position. The first driving mechanism 11 can drive the moving mechanism 40 to switch between the first position and the second position. When the moving mechanism 40 is in the second position, the moving mechanism 40 opens the middle air inlet mesh opening 221 and blocks the lower air inlet mesh opening 222. In this state, the oil fume treatment device 100 can have a good absorption effect on the oil fume generated by medium-height cookware, such as a wok, a medium-height cooking pot, etc.

[0124] By driving the switching of the moving mechanism 40 between the first position and the second position by the first driving mechanism 11, the oil fume treatment device 100 can always achieve a good adaptation effect for low-height cookware and medium-height cookware.

[0125] As Figure 7 and Figure 8 shown, after the cookware 200 has been cooking for a period of time, there may be a problem that the oil fume absorption effect of a single middle air inlet mesh opening 221 is insufficient, resulting in the diffusion and overflow of oil fume. When the physical property information of the oil fume detected by the oil fume physical property detection mechanism 82 exceeds the threshold, the control mechanism 50 controls the second driving mechanism 12 to act, so that the flap mechanism 30 opens. The flap mechanism 30 can achieve a good oil fume gathering effect, thereby achieving a good absorption effect of the oil fume treatment device 100 on the oil fume.

[0126] It should be noted that the opening angle of the flap mechanism 30 can increase with the increase of the oil fume physical property information P detected by the oil fume physical property detection mechanism 82, so as to realize the matching degree of the opening angle of the flap mechanism 30 with different oil fume conditions.

[0127] In an optional embodiment, as Figure 2 、 Figure 4 Figure 6 and Figure 7As shown, the first driving mechanism 11 includes a first linear driving mechanism 111 and a first guiding assembly 112. The first guiding assembly 112 includes a first guide rail 1121 and a first slider 1122 slidably disposed thereon. The first guide rail 1121 is disposed on the housing 20. The first body 1111 of the first linear driving mechanism 111 is rotatably connected to the housing 20, and the first output end 1112 of the first linear driving mechanism 111 is rotatably connected to the first slider 1122. The movable mechanism 40 is fixedly connected to the first slider 1122. When the first output end 1112 makes a telescopic movement relative to the first body 1111, the first output end 1112 can drive the first slider 1122 to slide along the first guide rail 1121, and the first slider 1122 can drive the movable mechanism 40 to slide along the extending direction of the first guide rail 1121, so as to realize the shielding or opening of the middle air inlet opening 221 or the lower air inlet opening 222 by the movable mechanism 40.

[0128] In an alternative embodiment, as Figure 2 , Figure 4 Figure 6 and Figure 7 shown, the first driving mechanism 11 is located on the back side of the first guiding assembly 112. By this arrangement, when the first linear driving mechanism 111 is in the most contracted state, the movable mechanism 40 can be in a relatively low position. That is to say, the lower air inlet opening 222 can be set at a sufficiently low position to meet the needs of different cookware 200 of customers.

[0129] Of course, in an alternative embodiment, the first body 1111 of the first linear driving mechanism 111 can also be indirectly fixed to the housing 20. The first body 1111 is disposed directly below the first slider 1122, which can effectively save the size of the oil fume treatment device 100 in the thickness direction and realize the thin and light setting of the oil fume treatment device 100.

[0130] In an alternative embodiment, the first driving mechanism 11 can only include the first linear driving mechanism 111. The first output end 1112 of the first linear driving mechanism 111 is directly connected to the movable mechanism 40. The first driving mechanism 11 with this structure can also realize the rapid adjustment of the position of the movable mechanism 40, and the structure of the first driving mechanism 11 with this structure is simple. It should be noted that the structure of the first driving mechanism 11 can also be other structures that can realize the sliding of the movable mechanism 40, and all structures that can realize the movement of the movable mechanism 40 are within the protection scope of the embodiments of the present disclosure.

[0131] In an alternative embodiment, the movable mechanism 40 may be an integral baffle (not shown in the figure). It has a simple structure and is easy to manufacture. The integral baffle can also better and more fully block the middle air inlet opening 221 or the lower air inlet opening 222, preventing oil fumes from overflowing from the movable mechanism 40.

[0132] In an alternative embodiment, as Figure 2 、 Figure 4 Figure 6 and Figure 7 shown, the movable mechanism 40 includes a movable plate 41 and a second guiding member 42. The movable plate 41 is fixedly connected to the second guiding member 42, and the second guiding member 42 is fixedly connected to the first slider 1122, and the second guiding member 42 and the first slider 1122 can achieve a firm connection.

[0133] In an alternative embodiment, as Figures 1 - 8 shown, a guiding groove 23 is formed on the housing 20. The second guiding member 42 is inserted into the guiding groove 23 and slides along the guiding groove 23. Through the cooperation between the second guiding member 42 and the guiding groove 23, the accurate switching of the position of the movable mechanism 40 can be achieved. In addition, the cooperation between the second guiding member 42 and the guiding groove 23 is compact, and corresponding structures can be arranged in a limited and narrow space to achieve an accurate guiding effect on the movable mechanism 40.

[0134] In an alternative embodiment, as Figures 1 - 8 shown, the second guiding member 42 can be provided with at least two. At least two second guiding members 42 are arranged at intervals along the width direction of the oil fume treatment device 100, so as to achieve a better guiding effect on the movable mechanism 40. In addition, through the arrangement of at least two second guiding members 42, the rotation or deflection of the movable mechanism 40 during movement can be avoided, and the guiding effect on the movable mechanism 40 can be further improved.

[0135] In an alternative embodiment, the second guiding member 42 can also be provided with one. Through the arrangement of one second guiding member 42, the structure of the oil fume treatment device 100 is simple and easy to assemble.

[0136] In an alternative embodiment, as Figure 1 、 Figure 3 、 Figure 5 、 Figure 7 、 Figure 9 and Figure 11As shown, the movable mechanism 40 further has a third position. An opening 411 is provided on the movable mechanism 40. The first driving mechanism 11 can drive the movable mechanism 40 to switch between the first position, the second position, and the third position. When the movable mechanism 40 is in the third position, the movable mechanism 40 opens the lower air inlet opening 222, and the opening 411 is directly opposite to the middle air inlet opening 221. In this state, the oil fume treatment device 100 can achieve a better absorption effect on a large amount of oil fume generated by low-height cookware or medium-height cookware, such as in scenarios where a large amount of oil fume is generated when using a flat frying pan, a baking tray, a wok, a medium-height cooking pot, etc.

[0137] By driving the movable mechanism 40 to switch between the first position, the second position, and the third position through the first driving mechanism 11, the oil fume treatment device 100 can always achieve a better adaptation effect for low-height cookware and medium-height cookware in different oil fume scenarios.

[0138] As Figure 11 and Figure 12 shown, after the cookware 200 has been cooking for a period of time, there may be a problem that when the lower air inlet opening 222 and the middle air inlet opening 221 are both open, the oil fume absorption effect is insufficient, resulting in the diffusion and overflow of oil fume. When the physical property information of the oil fume detected by the oil fume physical property detection mechanism 82 exceeds the threshold, the control mechanism 50 controls the second driving mechanism 12 to act, so that the flap mechanism 30 opens. The flap mechanism 30 can achieve a better oil fume gathering effect, thereby achieving a better absorption effect of the oil fume treatment device 100 on the oil fume.

[0139] It should be noted that the opening angle of the flap mechanism 30 can increase with the increase of the oil fume physical property information P detected by the oil fume physical property detection mechanism 82, so as to achieve the matching degree of the opening angle of the flap mechanism 30 with different oil fume conditions.

[0140] In an alternative embodiment, as Figure 13 and Figure 14 shown, the first air inlet 21, the middle air inlet opening 221, and the lower air inlet opening 222 are arranged from top to bottom. When the cookware physical property detection mechanism 81 detects that the height of the cookware 200 is relatively high, the second driving mechanism 12 can drive the flap mechanism 30 to be in an open state, so as to achieve a better absorption effect of the first air inlet 21 on the oil fume at a relatively high position. Such cookware includes, for example, a steamer, a cooking pot, a high-height cookware, etc.

[0141] In an alternative embodiment, as Figure 15 and Figure 16As shown, the movable mechanism 40 further has a fourth position. The first driving mechanism 11 can drive the movable mechanism 40 to switch among the first position, the second position, the third position and the fourth position. After the cookware 200 is cooked for a period of time, there may be a problem of insufficient oil fume suction effect, resulting in the diffusion and overflow of oil fume. When the physical property information of the oil fume detected by the oil fume physical property detection mechanism 82 exceeds the threshold, the control mechanism 50 controls the first driving mechanism 11 to act. The first driving mechanism 11 makes the movable mechanism 40 in the fourth position. The movable mechanism 40 further pushes the flap mechanism 30. The flap mechanism 30 can achieve a better oil fume gathering effect, so as to achieve a better oil fume absorption effect of the oil fume treatment device 100 for the oil fume.

[0142] It should be noted that the opening angle of the flap mechanism 30 can increase with the increase of the oil fume physical property information P detected by the oil fume physical property detection mechanism 82, so as to realize the matching degree of the opening angle of the flap mechanism 30 with different oil fume conditions.

[0143] In addition, as Figure 15 and Figure 16 shown, the movable mechanism 40, the flap mechanism 30 and the housing 20 together form an external smoke inlet cavity 60. The movable mechanism 40 opens both the middle air inlet mesh opening 221 and the lower air inlet mesh opening 222, which is equivalent to moving the first air inlet 21 inside to an external and relatively lower position, improving the smoking effect, and at the same time the flap mechanism 30 plays a role in gathering smoke. Exemplarily, the opening 411 is located in front of and below the first air inlet 21, and can achieve a better oil fume absorption effect.

[0144] By driving the movable mechanism 40 to switch among the first position, the second position, the third position and the fourth position through the driving assembly 10, the oil fume treatment device 100 can always achieve a better adaptation effect for cookware 200 at different heights.

[0145] In an alternative embodiment, as Figure 14 and Figure 16 shown, the flap mechanism 30 includes a flap body 31 and a first side baffle 32. The first side baffle 32 is arranged on both sides of the flap body 31. When the movable mechanism 40 is in the fourth position, the flap body 31, the first side baffle 32, the movable mechanism 40 and the housing 20 together form an external smoke inlet cavity 60. The setting of the first side baffle 32 can realize a closed external smoke inlet cavity 60, which can prevent the oil fume from diffusing or overflowing out of the external smoke inlet cavity 60, and ensure that the oil fume treatment device 100 always has a better oil fume absorption effect.

[0146] As Figure 16As shown, the shell 20 includes a front panel 24 and a rear panel 25 arranged at intervals along the front-to-back direction, a noise reduction chamber 26 is formed between the front panel 24 and the rear panel 25, the first air inlet 21 is arranged on the front panel 24, the flap body 31, the first side baffle 32, the movable mechanism 40 and the front panel 24 together constitute an external smoke inlet chamber 60, and the noise reduction chamber 26 and the external smoke inlet chamber 60 are arranged at intervals. Through the independent arrangement of the noise reduction chamber 26 and the external smoke inlet chamber 60, the noise generated by the internal mechanism of the shell 20 can be effectively isolated, and the noise generated by the internal mechanism of the shell 20 is prevented from being transmitted to the outside, and the bass use effect of the oil fume treatment device 100 can be achieved.

[0147] In an optional embodiment, if Figure 14 and Figure 16 As shown, the second driving mechanism 12 includes a second output end 121 and a second body 123. The second output end 121 can be extended and retracted in a linear direction relative to the second body 123. The second body 123 is rotationally connected to the outer shell 20. The second output end 121 is transmission-connected to the flip mechanism 30. When the second output end 121 performs an extension and retraction movement relative to the second body 123, the second output end 121 can push the flip mechanism 30 to rotate relative to the outer shell 20.

[0148] In addition, the first drive mechanism 11 and the second drive mechanism 12 can directly or indirectly apply external force to the flap mechanism 30 to rotate the flap mechanism 30 relative to the housing 20. In order to avoid interference between the flap mechanism 30 and the first drive mechanism 11 or the second drive mechanism 12, as shown in FIG. Figure 2 , Figure 4 , Figure 6 , Figure 8 , Figure 10 , Figure 12 , Figure 14 as well as Figure 16 As shown, the second driving mechanism 12 also includes a first guide member 122, which is arranged on the second output end 121. The flap mechanism 30 includes a second side baffle 33, and the second side baffle 33 is provided with an avoidance groove 331. The first guide member 122 is inserted into the avoidance groove 331 and can slide along the avoidance groove 331. When the movable mechanism 40 pushes the flap mechanism 30 to move, it can avoid interference between the flap mechanism 30 and the first driving mechanism 11.

[0149] When the first driving mechanism 11 or the second driving mechanism 12 is reset, there will be a problem of component jamming, resulting in incomplete reset of the flap mechanism 30, and there will be a gap between the flap mechanism 30 and the housing 20: on the one hand, it makes the oil fume treatment device 100 unsightly in the closed state; on the other hand, when the oil fume treatment device 100 is in the closed state, the oil fume inside the oil fume treatment device 100 will diffuse and overflow into the environment, which is likely to damage or affect the cleanliness of the environment and affect the user experience.

[0150] In an optional embodiment, to solve the above problems, as Figure 2 、 Figure 4 、 Figure 6 、 Figure 8 、 Figure 10 、 Figure 12 、 Figure 14 and Figure 16 shown, the oil fume treatment device 100 further includes a reset member 70. The flap mechanism 30 is rotatably connected to the housing 20. One end of the flap mechanism 30 is rotatably connected to the housing 20, and the other end of the flap mechanism 30 is connected to the reset member 70. When the first driving mechanism 11 or the second driving mechanism 12 is reset, the reset member 70 can achieve a better reset effect of the flap mechanism 30, so as to achieve a tight abutment between the flap mechanism 30 and the housing 20, thereby avoiding a gap between the flap mechanism 30 and the housing 20. On the one hand, it ensures better aesthetics of the oil fume treatment device 100 in the closed state; on the other hand, it can also prevent the oil fume inside the oil fume treatment device 100 from diffusing and overflowing into the environment, ensuring better cleanliness of the environment and better user experience.

[0151] In an optional embodiment, as Figure 2 、 Figure 4 、 Figure 6 、 Figure 8 、 Figure 10 、 Figure 12 、 Figure 14 and Figure 16 shown, the reset member 70 is connected to the lower end of the flap mechanism 30. The reset member 70 only needs to provide a small force to apply a large torque to the flap mechanism 30, so as to achieve a better reset effect of the flap mechanism 30.

[0152] Exemplarily, as Figure 2 、 Figure 4 、 Figure 6 、 Figure 8 、 Figure 10 、 Figure 12 、 Figure 14 and Figure 16 shown, the reset member 70 can be a spring, a reset cylinder, etc. All structures that can achieve the reset of the flap mechanism 30 are within the protection scope of the embodiments of the present disclosure.

[0153] Embodiment 2

[0154] As Figures 19 - 35 shown, an oil fume treatment device 100 is provided in an embodiment of the present disclosure. 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 driving assembly 10 includes a third driving mechanism 13 and a fourth driving mechanism 14. The third driving mechanism 13 adjusts the flap mechanism 30 and / or the movable mechanism 40 so that the one closest to the pot opening 210 of the cookware 200 in the air inlet net opening and the first air inlet 21 is in an open state; the fourth driving mechanism 14 can adjust the opening angle of the flap mechanism 30 according to the detected oil fume physical property information P. The fourth driving mechanism 14 only serves as the driving source for the action of the flap mechanism 30, making the overall control drive of the oil fume treatment device 100 simpler, and the third driving mechanism 13 and the fourth driving mechanism 14 will not interfere due to overly complex structures or control drives.

[0155] Among them, as Figures 19 - 35 shown, the structure of the third driving mechanism 13 is the same as that of the first driving mechanism 11 in Embodiment 1. The third driving mechanism 13 includes a third linear driving mechanism 131 and a third guiding assembly 132. The third guiding assembly 132 includes a third guide rail 1321 and a third slider 1322 slidably disposed thereon. The third guide rail 1321 is disposed on the housing 20. The third body 1313 of the third linear driving mechanism 131 is rotatably connected to the housing 20, and the third output end 1312 of the third linear driving mechanism 131 is rotatably connected to the third slider 1322. The movable mechanism 40 is fixedly connected to the third slider 1322. When the third output end 1312 makes a telescopic movement relative to the third body 1313, the third output end 1312 can drive the third slider 1322 to slide along the third guide rail 1321, and the third slider 1322 can drive the movable mechanism 40 to slide along the extension direction of the third guide rail 1321, so as to realize the shielding or opening of the middle air inlet net opening 221 or the lower air inlet net opening 222 by the movable mechanism 40.

[0156] As Figure 21 shown, the third driving mechanism 13 and the fourth driving mechanism 14 are respectively communicatively connected to the control mechanism 50. The third driving mechanism 13 and the fourth driving mechanism 14 cooperate to adjust the flap mechanism 30 and / or the movable mechanism 40 so that the one closest to the pot opening 210 of the cookware 200 in the air inlet net opening and the first air inlet 21 is in an open state. The fourth driving mechanism 14 can adjust the opening angle of the flap mechanism 30 according to the detected oil fume physical property information P. Through the settings of the third driving mechanism 13 and the fourth driving mechanism 14, independent and flexible adjustment of the flap mechanism 30 and the movable mechanism 40 can be achieved, so as to realize flexible adjustment of the oil fume treatment device 100 in different states.

[0157] As shown Figures 19 - 35 in the figure, the fourth driving mechanism 14 includes a fourth body 141 and a fourth output end 142. Among them, the fourth body 141 is fixedly connected to the housing 20, the fourth output end 142 can perform a linear telescopic motion relative to the fourth body 141, and the fourth output end 142 is in contact with the flap mechanism 30. Through the fourth driving mechanism 14, a better driving effect on the flap mechanism 30 can be achieved. In addition, since the fourth output end 142 is in contact with the flap mechanism 30, the state of the fourth driving mechanism 14 will not affect the working state of the third driving mechanism 13, and it can avoid jamming during the switching of different states of the oil fume treatment device 100.

[0158] Embodiment III

[0159] As shown Figure 36 in the figure, the present disclosure provides a control method for use with the oil fume treatment device 100 provided in Embodiment I or Embodiment II. The control method includes:

[0160] Obtaining the distances in the vertical direction between the first air inlet 21 and the second air inlet 22 and the pot opening 210 of the cookware 200 respectively, and the oil fume physical property information P;

[0161] According to the distances in the vertical direction between the first air inlet 21 and the second air inlet 22 and the pot opening 210 of the cookware 200 respectively, and the oil fume physical property information P, adjusting the positions and postures of the flap mechanism 30 and the movable mechanism 40, so that the oil fume treatment device 100 is in different working modes.

[0162] This control method can, according to the obtained distances in the vertical direction between the first air inlet 21 and the second air inlet 22 and the pot opening 210 of the cookware 200 respectively, and the oil fume physical property information P, the two types of parameters act synergistically to comprehensively and adaptively adjust the positions and postures of the flap mechanism 30 and the movable mechanism 40, so that the oil fume treatment device 100 is in different working modes, and can achieve better absorption of oil fume generated by different types of cookware 200 in different regions and at different heights, avoid the accumulation of oil fume in local areas, ensure good air quality, and ensure the physical health of users.

[0163] In addition, the control method of the embodiments of the present disclosure synergistically uses two types of parameters to comprehensively and adaptively adjust the positions and postures of the flap mechanism 30 and the movable mechanism 40, so that the oil fume treatment device 100 is in different working modes, without the need to use the prior art to capture oil fumes in different states by adjusting the wind speed. Therefore, there will be no problem of poor smoking effect caused by the change of wind speed, nor will there be large noise and energy consumption caused by the change of wind speed. Therefore, by using the oil control method of the embodiments of the present disclosure, it is possible to always capture different areas of oil fumes well, adapt the oil fume suction to different states of oil fumes, use low noise, and use low energy consumption, so as to achieve a good absorption of oil fumes in different forms, a good suction of oil fumes, a low-noise use of the oil fume treatment device 100, and a dynamic balance of low-energy consumption use, and achieve the optimal use performance of the oil fume treatment device 100.

[0164] Embodiment 4

[0165] This embodiment discloses a control method, which is basically the same as the control method of Embodiment 3. The control method of this embodiment is a further refinement of the control method of Embodiment 3. As Figure 37 shown, the control method includes:

[0166] S11: Obtain the distances in the vertical direction between the first air inlet 21 and the second air inlet 22 and the pot mouth 210 of the cookware 200 respectively;

[0167] S12: Determine the nearest air inlet, which is the nearest to the pot mouth 210, among the first air inlet 21 and the second air inlet 22 according to the distances in the vertical direction between the first air inlet 21 and the second air inlet 22 and the pot mouth 210 of the cookware 200 respectively;

[0168] S13: Adjust the flap mechanism 30 and / or the movable mechanism 40 to make the nearest air inlet in an open state;

[0169] S21: Obtain the oil fume physical property information P;

[0170] S22: Adjust the opening angle of the flap mechanism 30 according to the detected oil fume physical property information P.

[0171] Through S11 to S13, the states of the second air inlet 22 or the first air inlet 21 can be adjusted according to the heights of different cookwares 200, so as to ensure that the smoke inlet path is the shortest path, thereby improving the smoking effect and achieving better absorption of the oil fumes generated by the cookwares 200 with different heights.

[0172] Through S21 and S22, according to the detected oil fume physical property information P, the opening angle of the flap mechanism 30 is adjusted, so as to further improve the smoking effect for the range of oil fume areas generated by different types of cookwares 200.

[0173] In summary, through the control method of the embodiments of the present disclosure, different cookware situations can be flexibly handled, the accumulation of oil fumes in local areas can be avoided, good air quality can be ensured, and the physical health of users can be guaranteed.

[0174] It should be noted that the height of the cookware 200 has the greatest impact on the oil fume formation area. The shape and diameter of the cookware 200 will also have a certain impact on the oil fume formation area, but the impact is slightly weaker. Therefore, the selection of the first air inlet 21 or the second air inlet 22 can be adjusted first according to the height of the cookware 200, which can achieve a rapid and main adjustment of the oil fume treatment device 100. Then, continue to make more refined adjustments to the oil fume treatment device 100 according to the secondary influence parameters, which can achieve a better absorption effect on the oil fume areas formed by different cookwares. In summary, through the adjustment of the above two aspects in sequence, a rapid and accurate adjustment of the oil fume treatment device 100 can be achieved.

[0175] Furthermore, the method for determining the nearest air inlet is as follows:

[0176] Obtain the height of the pot mouth 210;

[0177] Determine the nearest air inlet according to the height of the pot mouth 210.

[0178] By simply detecting the height of the pot mouth 210, the rapid determination of the nearest air inlet can be achieved.

[0179] Exemplarily, the height of the pot mouth 210 can be detected by the cookware physical property detection mechanism 81. The cookware physical property detection mechanism 81 can be an ultrasonic distance detection mechanism, a laser distance detection mechanism, an image forming mechanism, etc. All cookware physical property detection mechanisms 81 that can directly or indirectly obtain the height of the pot mouth 210 are within the protection scope of the embodiments of the present disclosure.

[0180] Embodiment 5

[0181] This embodiment discloses a control method, which is basically the same as the control method of Embodiment 4. The control method of this embodiment is a further refinement of the control method of Embodiment 4. As Figure 38 shown, the control method includes:

[0182] S111: Obtain the height H of the pot mouth 210;

[0183] S112: According to the height H of the pot mouth 210, calculate and obtain: the first distance D in the vertical direction between the first air inlet 21 and the pot mouth 210 上 and the second distance D in the vertical direction between the middle air inlet mesh 221 and the pot mouth 210 中And the third distance D in the vertical direction between the lower air inlet opening 222 and the pot opening 210 下 ;

[0184] Specifically, as Figure 18 shown, D 上 = |H 挂 + h 上 - H|; D middle = |H 挂 + h 中 - H|; D lower = |H 挂 + h 下 - H|;

[0185] Among them, H 挂 is the vertical distance from the lower end of the oil fume treatment device 100 to the stove top 300; h 上 is the vertical distance from the first air inlet 21 to the lower end of the oil fume treatment device 100, h 中 is the vertical distance from the upper middle air inlet opening 221 to the lower end of the oil fume treatment device 100, h 下 is the vertical distance from the lower air inlet opening 222 to the lower end of the oil fume treatment device 100.

[0186] Through the above formula, the first distance D 上 , the second distance D 中 and the third distance D 下 can be obtained quickly and accurately, and the nearest air inlet can be determined quickly.

[0187] S121: Judge whether D 下 is less than D 中 : If so, perform S131; if not, perform S122;

[0188] S131: Control the movable mechanism 40 to be in the first position as shown in Figure 1 and Figure 2 shown, and control the flap mechanism 30 to be in the closed position;

[0189] According to S121 and S131, if D 下 < D 中 , it means that the pot opening 210 is closest to the lower air inlet opening 222. When the movable mechanism 40 is in the first position, the movable mechanism 40 opens the lower air inlet opening 222 and blocks the middle air inlet opening 221. At this time, the lower air inlet opening 222 is the main air suction port, and a better absorption effect on the oil fume generated by the pot opening 210 can be achieved.

[0190] S211: Obtain the oil fume physical property information P;

[0191] S221: Determine whether the oil fume physical property information P is greater than the first threshold: If so, proceed to S222; if not, return to S211;

[0192] S222: Control the flap mechanism 30 to be in the first open position as shown in Figure 3 and Figure 4 ;

[0193] Determining whether the oil fume physical property information P is greater than the first threshold indicates that there will be a situation of oil fume escaping in this state of the oil fume treatment device 100. Therefore, control the flap mechanism 30 to be in the first open position as shown in Figure 3 and Figure 4 . The flap mechanism 30 can achieve a better gathering and guiding effect on the oil fume, and can effectively reduce the problem of oil fume overflow.

[0194] S122: Determine whether D 中 is less than D 上 : If so, proceed to S132; if not, proceed to S133;

[0195] S132: Control the movable mechanism 40 to be in the second position as shown in Figure 5 and Figure 6 , and control the flap mechanism 30 to be in the closed position;

[0196] According to S122 and S132, if D 中 <D 上 , it means that the pot mouth 210 is closest to the middle air inlet net mouth 221. When the movable mechanism 40 is in the second position, the movable mechanism 40 opens the middle air inlet net mouth 221 and blocks the lower air inlet net mouth 222. At this time, the middle air inlet net mouth 221 is the main air suction port, and can achieve a better absorption effect on the oil fume generated by the pot mouth 210.

[0197] S212: Obtain the oil fume physical property information P;

[0198] S223: Determine whether the oil fume physical property information P is greater than the second threshold: If so, proceed to S224; if not, return to S212;

[0199] S224: Control the flap mechanism 30 to be in the first open position as shown in Figure 7 and Figure 8 ;

[0200] Determining whether the oil fume physical property information P is greater than the second threshold indicates that there will be a situation of oil fume escaping in this state of the oil fume treatment device 100. Therefore, control the flap mechanism 30 to be in the first open position as shown in Figure 5 and Figure 6 . The flap mechanism 30 can achieve a better gathering and guiding effect on the oil fume, and can effectively reduce the problem of oil fume overflow.

[0201] S133: Control the movable mechanism 40 to be in the third position as shown in Figure 13 and Figure 14 shown, and control the flap mechanism 30 to be in the first open position;

[0202] According to S122 and S132, if D 中 ≥D 上 , it indicates that the pot mouth 210 is closest to the first air inlet 21. At this time, the middle air inlet network port 221 is the main suction port. Controlling the flap mechanism 30 to be in the first open position can achieve a better absorption effect on the oil fume generated at the pot mouth 210.

[0203] S213: Obtain the oil fume physical property information P;

[0204] S225: Determine whether the oil fume physical property information P is greater than the third threshold value: If so, proceed to S226; if not, return to S213;

[0205] S226: Control the flap mechanism 30 to be in the second open position as shown in Figure 15 and Figure 16 shown.

[0206] Determine whether the oil fume physical property information P is greater than the third threshold value, which indicates that there will be a situation of oil fume escape in the oil fume treatment device 100 in this state. Therefore, control the flap mechanism 30 to be in the second open position as shown in Figure 15 and Figure 16 shown, further increasing the opening angle of the flap mechanism 30. The flap mechanism 30 can achieve a better gathering and guiding effect on the oil fume, and can effectively reduce the problem of oil fume overflow.
