Description

Technical Field

[0001] This utility model relates to the field of kitchen appliance technology, and in particular to a smoke guide plate mechanism and an oil fume treatment device. Background Technology

[0002] Some range hoods include a smoke collection chamber body, an upper flap assembly, a second flap assembly, a fan, and a drive mechanism. The smoke collection chamber body has an air inlet. The upper flap assembly is hinged to the smoke collection chamber body, and the second flap assembly is driven by the upper flap assembly. The drive mechanism can mechanically drive the upper and second flap assemblies to open or close the air inlet. A fan is installed inside the smoke collection chamber body. When the fan operates, it generates negative pressure, drawing cooking fumes from outside the smoke collection chamber body into it and ultimately expelling them. The concentration of cooking fumes varies in different cooking scenarios. While existing range hoods can adjust the shape of the upper and second flap assemblies to change the size of the air inlet and the smoke collection range, their adjustment flexibility is poor. Furthermore, the air inlet of a range hood generally faces both the cooking appliances and the user. The noise generated by the fan inside the smoke collection chamber body when operating will be transmitted to the user's ears through the air inlet, resulting in a poor user experience.

[0003] Therefore, there is an urgent need for an oil fume treatment device and its control method to solve the above-mentioned technical problems. Utility Model Content

[0004] The purpose of this utility model is to propose a smoke guide plate mechanism and an oil fume treatment device. The flipping angles of the first flap assembly and the second flap assembly can be adjusted independently, and in conjunction with the linkage of the air inlet plate assembly, the oil fume treatment device can ensure good oil fume absorption effect while taking into account noise reduction requirements.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] The smoke guide plate mechanism includes:

[0007] The first flap assembly is hinged to the main body of the fume collection chamber of the fume treatment device;

[0008] The second flap assembly is hinged to the first flap assembly;

[0009] An air inlet plate assembly is provided with an air inlet. One end of the air inlet plate assembly is hinged to the main body of the smoke collection chamber, and the other end is drivenly connected to the first flap plate assembly so that it flips outward synchronously when the first flap plate assembly flips outward, and forms an angle with the second flap plate assembly.

[0010] A first driving component is used to drive the first flap component to flip relative to the smoke collection chamber body;

[0011] The second driving component is used to drive the second flip panel component to flip relative to the first flip panel component.

[0012] As an optional solution, the fume treatment device further includes a linkage component, which includes a slide rail and a slide rod. The slide rail is mounted on the first flap assembly, and one end of the slide rod can slide along the slide rail, while the other end is hinged to the air inlet plate assembly, so that when the first flap assembly flips outward relative to the main body of the fume collection chamber, it can drive the air inlet plate assembly to flip outward relative to the main body of the fume collection chamber.

[0013] As an optional solution, the linkage component further includes a slider and a first fastener. The slider slides in conjunction with the slide rail. One of the slider and the slide rod is provided with an arc-shaped groove, and the other is provided with a mounting hole. The first fastener passes through the arc-shaped groove and the mounting hole to fasten the slider and the slide rail.

[0014] As an optional solution, a first bracket is provided on the inner side of the first flap assembly. The first bracket has a mounting surface perpendicular to the hinge axis between the first flap assembly and the main body of the smoke collection chamber. The slide rail is mounted on the mounting surface, and the arc-shaped groove is parallel to the mounting surface.

[0015] As an optional solution, the first drive assembly includes an electric actuator, the main body of which is hinged to the main body of the smoke collection chamber, and the output end of which is hinged to the first flap assembly.

[0016] As an optional solution, the second drive assembly is mounted on the first flap assembly and can output rotational motion. The smoke guide plate mechanism also includes a linkage transmission assembly, the output end of the second drive assembly is hinged to one end of the linkage transmission assembly, and the other end of the linkage transmission assembly is hinged to the second flap assembly.

[0017] As an optional solution, the linkage drive assembly includes a first link, a second link, and a third link, wherein the output end of the second drive assembly, the first link, the second link, the third link, and the second flap assembly are sequentially hinged to form a four-link structure.

[0018] As an optional solution, the air inlet plate assembly is provided with a clearance hole, and the linkage drive assembly passes through the clearance hole to connect the output end of the second drive assembly and the second flap assembly.

[0019] As an optional solution, the fume treatment device further includes a user height detection component, which is used to detect the height of a user located in front of the fume treatment device, and the second drive component is communicatively connected to the user height detection component.

[0020] The fume treatment device includes a fume collection chamber body and the aforementioned fume guide plate mechanism.

[0021] The beneficial effects of this utility model are:

[0022] The smoke guide plate mechanism of this utility model includes a first flap assembly, a second flap assembly, and an air inlet plate assembly. The smoke collection chamber body, the first flap assembly, and the second flap assembly are hinged sequentially. The air inlet plate assembly is hinged to the smoke collection chamber body and linked with the first flap assembly. The first drive assembly can drive the first flap assembly to flip outward, thereby opening the opening on the smoke collection chamber body. At the same time, the air inlet plate assembly is linked with the first flap assembly and flips outward, thereby increasing the volume of the smoke collection chamber and expanding the negative pressure, bringing the negative pressure closer to the source of oil fumes and improving the oil fume extraction effect of the oil fume treatment device. When the angle of the second flap assembly flipping outward relative to the first flap assembly increases, the oil fume extraction capacity of the oil fume treatment device increases, but the noise blocking effect deteriorates. By setting the second drive assembly to independently drive the second flap assembly to flip outward relative to the first flap assembly, the smoke collection range and noise blocking effect of the smoke guide plate mechanism can be adjusted more flexibly. This ensures that the current oil fume treatment device has a good oil fume extraction capacity while minimizing the noise transmitted to the user's ears, thus improving the user experience.

[0023] The oil fume treatment device of this utility model, by adopting the above-mentioned smoke guide plate mechanism, can ensure good oil fume absorption effect while taking into account the noise reduction requirement. Attached Figure Description

[0038] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the invention. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not the entire structure.

[0039] In the description of this utility model, 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. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0040] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. 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. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0041] In the description of this embodiment, the terms "upper," "lower," "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 this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0042] This embodiment provides a smoke guide plate mechanism and an oil fume treatment device, wherein the oil fume treatment device can be a range hood, integrated stove, etc. The following description uses a range hood as an example of the oil fume treatment device. Furthermore, the descriptions of up, down, left, right, front, and rear directions in the following text are all relative to the user when the oil fume treatment device is working normally.

[0043] like Figure 1 and Figure 2 As shown, the fume treatment device includes a fume collection chamber body 10, a fan assembly 70, and a smoke guide plate mechanism. The fume collection chamber body 10 has an opening 11. The smoke guide plate mechanism is connected to the fume collection chamber body 10 and, together with the fume collection chamber body 10, forms a fume collection chamber that can open and close the opening 11. The fan assembly 70 is installed inside the fume collection chamber body 10 and is used to create negative pressure within the fume collection chamber, thereby drawing fumes from outside the fume treatment device into the fume collection chamber and ultimately discharging them outdoors, improving the kitchen environment.

[0044] Specifically, such as Figure 1 and Figure 2As shown, the smoke guide plate mechanism includes a first flap assembly 21, a second flap assembly 22, an air inlet plate assembly 23, a first drive assembly 41, and a second drive assembly 42. The smoke collection chamber body 10, the first flap assembly 21, and the second flap assembly 22 are sequentially hinged. The air inlet plate assembly 23 is provided with an air inlet 231. One end of the air inlet plate assembly 23 is hinged to the smoke collection chamber body 10, and the other end is drively connected to the first flap assembly 21 so that it flips outward synchronously when the first flap assembly 21 flips outward, forming an angle with the second flap assembly 22. The first drive assembly 41 is used to drive the first flap assembly 21 to flip relative to the smoke collection chamber body 10. The second drive assembly 42 is used to drive the second flap assembly 22 to flip relative to the first flap assembly 21.

[0045] In this embodiment of the fume treatment device, when the first driving component 41 drives the first flap component 21 to flip outward, the opening 11 on the fume collection chamber body 10 is opened. The first flap component 21 drives the air inlet plate component 23 to flip outward relative to the fume collection chamber body 10, thereby increasing the volume of the fume collection chamber, expanding the negative pressure, and bringing it closer to the source of the fume, thus improving the fume extraction effect. When the second driving component 42 drives the second flap component 22 to flip outward relative to the first flap component 21, the angle between the second flap component 22 and the air inlet plate component 23 increases. It can be understood that the larger the angle between the second flap component 22 and the air inlet plate component 23, the larger the fume collection range of the guide plate mechanism, and the stronger the fume extraction capacity of the fume treatment device, but the noise blocking effect becomes worse. In this embodiment, the second first driving component 41 and the second driving component 42 of the smoke guide plate mechanism independently drive the first flip plate component 21 and the second flip plate component 22 to flip, which can more flexibly adjust the size of the smoke collection chamber, the smoke gathering range of the smoke guide plate mechanism, and the noise blocking effect, so as to minimize the noise transmitted to the user's ears while ensuring that the current oil fume treatment device has a better oil fume extraction capacity, thereby improving the user experience.

[0046] like Figure 1 and Figure 2 As shown, the opening 11 of the smoke collection chamber body 10 is located on its front side. The upper end of the first flap assembly 21 is hinged to the upper end of the smoke collection chamber body 10. Specifically, the first flap assembly 21 can be hinged to the inner wall of the smoke collection chamber body 10 via a hinge. The upper end of the second flap assembly 22 is hinged to the lower end of the first flap assembly 21. Specifically, the second flap assembly 22 and the first flap assembly 21 can be hinged via a hinge, pivot shaft structure, etc., which is not limited here. The lower end of the air inlet plate assembly 23 is hinged to the smoke collection chamber body 10, and the upper end of the air inlet plate assembly 23 is drively connected to the first flap assembly 21. Wherein, as Figure 2As shown, a first hinge seat 12 is provided inside the smoke collection chamber body 10, and a hinge portion 232 is provided on the inner side of the air inlet plate assembly 23. The hinge portion 232 is hinged to the first hinge seat 12, thereby realizing the hinge between the air inlet plate assembly 23 and the smoke collection chamber body 10. It should be noted that in this embodiment, the hinge axis between the first flap assembly 21 and the smoke collection chamber body 10, the hinge axis between the second flap assembly 22 and the first flap assembly 21, and the hinge axis between the air inlet plate assembly 23 and the smoke collection chamber body 10 are parallel to each other. In this embodiment, when the smoke guide plate mechanism closes the opening 11 of the smoke collection chamber body 10, the first flap assembly 21 and the second flap assembly 22 are coplanar and approximately in a vertical plane, and the air inlet plate assembly 23 is located inside the smoke collection chamber and is basically parallel to the second flap assembly 22.

[0047] like Figure 2 and Figure 3 As shown, the first drive assembly 41 includes an electric actuator, the main body of which is hinged to the smoke collection chamber body 10, and the output end of which is hinged to the first flap assembly 21. When the output end of the electric actuator extends, the first flap assembly 21 flips outward relative to the smoke collection chamber body 10, and simultaneously the air inlet plate assembly 23 flips outward relative to the smoke collection chamber body 10. When the output end of the electric actuator retracts, the first flap assembly 21 flips inward relative to the smoke collection chamber body 10, and the air inlet plate assembly 23 also flips inward relative to the smoke collection chamber body 10. It can be understood that there is a one-to-one correspondence between the angle between the lower side of the first flap assembly 21 and the vertical direction, and the first angle between the upper side of the air inlet plate assembly 23 and the vertical direction, and the magnitudes of the two change in the same direction. Specifically, a second bracket 13 is provided on the inner side of the smoke collection chamber body 10, the main body of the electric push rod is hinged to the second bracket 13, a second hinge seat 211 is provided on the inner side of the first flap assembly 21, and the output end of the electric push rod is hinged to the second hinge seat 211.

[0048] like Figure 2 and Figure 3 As shown, the second drive assembly 42 is mounted on the first flap assembly 21 and can output rotational motion. The smoke guide plate mechanism also includes a linkage transmission assembly 60, one end of which is hinged to the second drive assembly 42, and the other end is hinged to the second flap assembly 22. By setting the second drive assembly 42 on the first flap assembly 21, it can be ensured that the rotation angle of the second flap assembly 22 relative to the first flap assembly 21 is not affected by the rotation of the first flap assembly 21, and the structure is simpler. Optionally, in this embodiment, the second drive assembly 42 includes a geared motor. A mounting base 212 is provided on the inner side of the first flap assembly 21, and the geared motor is mounted on the mounting base 212.

[0049] In order to achieve the transmission between the second drive assembly 42 and the second flap assembly 22, such as Figure 2 and Figure 3As shown, the linkage transmission assembly 60 includes a first link 61, a second link 62, and a third link 63. The output end of the second drive assembly 42, the first link 61, the second link 62, the third link 63, and the second flap assembly 22 are sequentially hinged to form a four-bar linkage. When the second drive assembly 42 outputs rotational motion, the second flap assembly 22 rotates around its hinge axis with the first flap assembly 21. Optionally, two or more sets of linkage transmission assemblies 60 can be provided between the first flap assembly 21 and the second flap assembly 22. These two or more sets of linkage transmission assemblies 60 are arranged at intervals along the left-right direction of the second flap assembly 22, thereby ensuring uniform force distribution on the second flap assembly 22 and improving the smoothness of its rotation. Figure 3 As shown, the air inlet plate assembly 23 is provided with a clearance hole 233. One end of the connecting rod transmission assembly 60 is located inside the smoke collection chamber, and the other end passes through the clearance hole 233 to connect with the second flap assembly 22 located outside the smoke collection chamber. In this embodiment, the third connecting rod 63 passes through the clearance hole 233.

[0050] To ensure that when the first flap assembly 21 flips outward relative to the smoke collection chamber body 10, the air inlet plate assembly 23 also flips outward accordingly, such as... Figure 2 and Figure 3 As shown, the fume treatment device also includes a linkage component 50, which includes a slide rail 51 and a slide rod 52. The slide rail 51 is mounted on the first flap assembly 21, and the slide rod 52 can slide along the slide rail 51. The other end of the slide rod 52 is hinged to the air inlet plate assembly 23. When the first drive assembly 41 drives the first flap assembly 21 to flip outward relative to the smoke collection chamber body 10, the slide rod 52 slides along the slide rail 51, and simultaneously the air inlet plate assembly 23 rotates relative to the first hinge seat 12, thereby realizing the outward flipping of the air inlet plate assembly 23 relative to the smoke collection chamber body 10. In this embodiment, the slide rod 52 is hinged to the air inlet plate assembly 23 by hinged to the hinge part 232. Optionally, as... Figure 2 As shown, two or more sets of linkage components 50 can be set between the first flap assembly 21 and the air inlet plate assembly 23. The two or more sets of linkage components 50 are arranged at intervals in the left and right directions, so that the air inlet plate assembly 23 is subjected to more uniform force and rotates more smoothly.

[0051] Due to the processing and assembly errors of the components between the first flap assembly 21 and the air inlet assembly 23, there may be a large cumulative error, which will eventually lead to the motion of the assembled smoke guide plate mechanism being not smooth enough, increasing the difficulty of assembling and debugging the fume treatment device.

[0052] In this regard, such as Figures 2-4As shown, the linkage component 50 also includes a slider (covered by the slide rod 52 in the figure) and a first fastener 53. The slider slides in conjunction with the slide rail 51. One of the slider and the slide rod 52 is provided with an arc groove 521, and the other is provided with a mounting hole. The first fastener 53 passes through the arc groove 521 and the mounting hole to secure the slider and the slide rail 51. When the smoke guide plate mechanism is installed on the smoke collection chamber body 10 and a jamming problem is found between the first flap assembly 21 and the air inlet plate assembly 23, the first fastener 53 can be loosened, and the relative position of the arc groove 521 and the mounting hole can be adjusted to adjust the angle of the slide rod 52 relative to the slide rail 51. Finally, the first fastener 53 is tightened. Through the adjustment of the above-mentioned fine-tuning structure (i.e., the structure composed of the arc groove 521, the mounting hole, and the first fastener 53), the cumulative error can be easily compensated, ensuring the smooth operation of the smoke guide plate mechanism and also improving the assembly and debugging difficulty of the fume treatment device. Furthermore, after the fume treatment device has been used for a long time, if the smoke guide plate mechanism experiences problems such as jamming or malfunction, the outer casing of the fume treatment device can be disassembled, and repairs can be performed by adjusting the aforementioned fine-tuning structure. In this embodiment, the arc-shaped groove 521 is provided on the slide rod 52, the mounting hole can be a threaded hole, and the first fastener 53 can be a bolt or screw.

[0053] like Figure 2 and Figure 3 As shown, a first bracket 213 is provided inside the first flap assembly 21. The first bracket 213 has a mounting surface perpendicular to the hinge axis between the first flap assembly 21 and the smoke collection chamber body 10. The slide rail 51 is mounted on the mounting surface and parallel to the mounting surface. After the slider is connected to the slide rail 51, the arc groove 521 on the slide rod 52 is parallel to the mounting surface, thereby ensuring the relative position adjustment between the arc groove 521 and the mounting hole, which can effectively solve the jamming problem between the first flap assembly 21 and the air inlet plate assembly 23. In this embodiment, the first bracket 213 is constructed as a plate with an L-shaped cross-section. One wall plate of the first bracket 213 is connected to the first flap assembly 21, and the other wall plate forms the aforementioned mounting surface and is used for mounting the slide rail 51.

[0054] In some embodiments, such as Figure 4As shown, the linkage component 50 also includes a second fastener 54, which passes through the slide rod 52 and the slider to lock them together. The cooperation of the first fastener 53 and the second fastener 54 improves the reliability of the connection between the slide rod 52 and the slider, preventing loosening or misalignment during prolonged use of the fume treatment device and reducing the risk of jamming in the smoke guide plate mechanism. It is understood that during the assembly and debugging of the fume treatment device, the second fastener 54 can be left uninstalled until the smooth operation of the smoke guide plate mechanism is confirmed. Optionally, the second fastener 54 can also be a bolt or screw, passing through the corresponding hole on the slide rod 52 and connected to the sliding thread.

[0055] The concentration of cooking fumes and the temperature of the cookware vary depending on the cooking scenario. Therefore, as... Figure 1 As shown, the fume treatment device in this embodiment also includes a control component (not shown) and a signal detection component 32. The signal detection component 32 is used to detect the fume concentration and / or temperature. The signal detection component 32 communicates with the first drive component 41 and the second drive component 42 through the control component. The first drive component 41 can adjust the size of the first angle between the upper side of the air inlet plate assembly 23 and the vertical direction, at least based on the detection result of the signal detection component 32. The second drive component 42 can adjust the size of the second angle β, at least based on the detection result of the signal detection component 32. With this configuration, the attitude adjustments of the first flap assembly 21 and the second flap assembly 22 by the first drive component 41 and the second drive component 42 respectively refer to the current fume concentration state. This not only ensures that the fume extraction capacity of the fume treatment device matches the current fume concentration, but also minimizes the noise transmitted to the user's ears, improving the user experience.

[0056] In this embodiment, the signal detection component 32 detects the oil fume concentration in the area in front of the oil fume treatment device and the temperature of the cookware below the oil fume treatment device. In some embodiments, the oil fume concentration detected by the signal detection component 32 may also be the oil fume concentration inside the smoke collection chamber; this is not specifically limited here. In this embodiment, the signal detection component 32 includes an oil fume concentration detection component and a temperature detection component, wherein the oil fume concentration detection component is used to detect the oil fume concentration outside the oil fume treatment device, and the temperature detection component is used to detect the temperature of the cookware.

[0057] When the fume treatment device is working, the noise generated by the fan assembly 70 is transmitted to the outside of the fume collection chamber through the opening 11 on the main body 10 of the fume collection chamber, resulting in a poor user experience. The applicant found that the first flap assembly 21 and the second flap assembly 22 not only effectively collect smoke but also impede noise to some extent. However, directly reducing the first angle between the upper side of the air inlet plate assembly 23 and the vertical direction, and reducing the second angle between the second flap assembly 22 and the air inlet plate assembly 23, while reducing noise, significantly sacrifices the fume extraction capacity. Therefore, the applicant further considered that improving the user experience does not necessarily require preventing noise from propagating outside the fume treatment device; it is sufficient to reduce the noise reaching the user's ears.

[0058] In this regard, such as Figure 1 and Figure 3 As shown, the fume treatment device also includes a user height detection component 31, which is used to detect the height of a user located in front of the fume treatment device. The user height detection component 31 communicates with the control component, thereby establishing a communication connection with the second drive component 42. The second drive component 42 can adjust the size of the second included angle between the second flap assembly 22 and the air inlet plate assembly 23 based on the detection results of the signal detection component 32 and the user height detection component 31. Specifically, when a user is tall, their ears are positioned relatively high, making it easier for noise received by the user to be blocked by the smoke guide plate mechanism. Therefore, the size of the first angle between the upper side of the air inlet plate assembly 23 and the vertical direction, and the second angle between the second flap assembly 22 and the air inlet plate assembly 23, can be appropriately increased to ensure both a better smoke extraction effect and less noise perceived by the user. When a user is short, their ears are positioned relatively low, making it easier for noise to be transmitted directly to the user's ears. In this case, while ensuring a better smoke extraction effect, the second angle between the second flap assembly 22 and the air inlet plate assembly 23 can be appropriately reduced to decrease the noise perceived by the user and improve the user experience. In other words, when the second drive component 42 adjusts the second included angle between the second flap component 22 and the air inlet component 23, it takes into account the oil fume concentration and / or temperature information, as well as the user's height information. This allows the actual shape of the smoke guide plate mechanism 20 to ensure a better oil fume extraction effect while also blocking noise from reaching the ears of users of the corresponding height as much as possible, thereby reducing the noise perceived by the user and improving the user experience.

[0059] Furthermore, it should be noted that, based on the specific structure of the smoke guide plate mechanism, the shape of the second flap assembly 22 has a more direct and effective noise blocking effect. Therefore, the second drive assembly 42 adjusts the size of the second included angle β between the second flap assembly 22 and the air inlet plate assembly 23 based on the user's height information, which can more directly and effectively adjust the noise propagation path, so as to block the noise from directly propagating to the ears of users of the corresponding height, reduce the noise perceived by the user, and improve the user experience. In addition, in this embodiment, the angle of the first flap assembly 21, that is, the adjustment of the first included angle α between the upper side of the air inlet plate assembly 23 and the vertical direction, is not based on the user's height information, which can also ensure the overall smoke extraction effect, thereby better balancing the smoke extraction effect and reducing the noise perceived by the user. Specifically, in this embodiment, the user height detection component 31 achieves communication connection with the second drive assembly 42 through the control component.

[0060] In this embodiment, the user height detection component 31 can be a wide-angle camera, etc. After acquiring an image of the user in front of the fume treatment device, the user height detection component 31 sends it to the control component, which analyzes the image to obtain the user's height information. Optionally, the user height detection component 31 can be located on the front side of the fume collection chamber body 10, specifically in the portion below the opening 11. Optionally, the user height detection component 31 can be integrated with the signal detection component 32 and installed on the front side of the fume collection chamber body 10.

[0061] In summary, in this embodiment, after the signal detection component 32 detects the oil fume concentration information and temperature information, it sends them to the control component. The control component identifies the current external cooking mode based on this information, so as to retrieve the appropriate specific value of the first included angle (hereinafter referred to as the first value α1) and the set of values ​​of the second included angle. Then, based on the user's height information, the control component retrieves the specific value of the second included angle that matches the user's height from the retrieved set of values ​​of the second included angle (hereinafter referred to as the second value β1). When the drive mechanism drives the smoke guide plate mechanism 20 to operate according to the retrieved first value α1 and second value β1, the oil fume treatment device can achieve both better oil fume absorption effect and reduced noise perceived by the user.

[0062] The table below provides a specific value rule for the first value α1 of the first angle between the upper side of the air inlet panel assembly 23 and the vertical direction, and the second value β1 of the second angle between the second flap assembly 22 and the air inlet panel assembly 23:

[0063] In the table above, the range of the first value α1 indicates that α1 can be any value within the corresponding range, and this value needs to be pre-stored in the control component. Similarly, the second value β1 can be any value within the corresponding range, and this value also needs to be pre-stored in the control component. Furthermore, it should be noted that if either the current fume concentration or temperature meets the value range of the previous setting, then both the first value α1 and the second value β1 will be retrieved from the previous setting. For example, if the fume concentration is greater than 15 mg / m³... 3 However, if the temperature is less than 200℃, the range of the first value α1 is 35° (inclusive) to 45° (inclusive), and the range of the second included angle β1 is 95° (inclusive) to 115° (inclusive). The specific value of the second included angle β1 needs to be further determined based on the user's height.
