[0059] Embodiment 1

[0060] Figure 1 is a schematic flowchart of a wind deflector control method provided by Embodiment 1 of the present invention. Figure 2 is a schematic structural diagram of a side-suction range hood provided by Embodiment 1 of the present invention. First, refer to Figure 2 , in which the wind deflector 2 is installed on the range hood 1, and the range hood 1 is arranged above a cooking stove (not shown in the figure). In the embodiment of the present invention, the range hood 1 is used to represent the fume extraction device, which is not a limitation. In addition to the range hood, those skilled in the art can also consider applying it to other fume extraction devices such as integrated stoves. This method can be executed by a processor in the range hood. In this embodiment, as Figure 1 shown, the wind deflector control method includes the following steps:

[0061] S110. Obtain a user's body posture image.

[0062] This step is essentially implemented by a camera sensor (not shown in the figure) to collect images. The camera sensor can be installed on the range hood, and the images collected by the camera are provided to the processor. After the processor obtains the user's body posture image collected by the camera, it can identify the image through a specific algorithm.

[0063] S120. Determine the user's height according to the user's body posture image.

[0064] This process is a process of identifying and analyzing the image. Those skilled in the art know that through image recognition technology, the user in the image can be identified, and then the actual height of the user can be calculated and obtained according to the corresponding proportional size. It should be noted that steps S110 and S120 can determine the user's height through the recognition of the user's full body image, or can also determine the user's height according to the comparison relationship between the user's head and the reference object in the image. The actual algorithms and principles are not limited in this embodiment.

[0065] S130. Determine the spatial position relationship between the user's height and the known height of the fume exhaust device, and determine the target gear of the air deflector according to the spatial position relationship; wherein, at the target gear, the connection line between the air deflector and the user's eyes and the cooking appliance does not intersect.

[0066] In this embodiment, the air deflector 2 has multiple gears in the open state. At different gears, the degree of opening of the air deflector 2 from the range hood 1 is different, and the shape of the air deflector 2 is different. This step takes into account the risk that the air deflector 2 installed on the range hood 1 may block the user's line of sight when it is opened. And at the target gear, the connection line between the air deflector 2 and the user's eyes and the cooking appliance does not intersect, which means that the shape of the air deflector 2 at the target gear will not block the user's line of sight and will not prevent the user from observing the state of the cookware and the food in it.

[0067] Specifically, to determine the target gear, it is essentially necessary to set each gear of the air deflector 2 in advance. Through the known height of the range hood 1, the shape of the air deflector at different gears can be determined. Furthermore, it is necessary to know the user's height, and the spatial geometric relationship can be used to calculate whether the air deflector in various shapes blocks the user's line of sight.

[0068] In a specific embodiment, in the above step S130, to determine the target gear of the air deflector according to the spatial position relationship, it may specifically include: determining the target opening angle gear of the air deflector according to the spatial position relationship.

[0069] Exemplarily, such as Figure 2As shown in the figure, taking the opening and closing angles of the air deflector 2 relative to the range hood 1 as an example of different gears, when the user is relatively tall (as shown by the eyes in the solid line in the figure), and the air deflector 2 is at the opening and closing angle corresponding to the air deflector 2 shown by the solid line in the figure, there will be a situation where the air deflector 2 blocks the user's line of sight (solid line). At this time, it is necessary to control the air deflector 2 to adjust to a gear with a smaller opening and closing angle. It can be seen from the figure that different heights correspond to a gear with the largest opening and closing angle that does not block the line of sight. Obviously, the opening and closing angle of the air deflector 2 that does not block the user's line of sight depends on the user's height. In other words, since the air deflector 2 is set on the range hood 1, whether the opening and closing angle of the air deflector 2 at each gear blocks the user's line of sight depends on the relative height of the user and the range hood 1. Therefore, through this step S130, the geometric relationship of space can be used to calculate the opening and closing angle gear of the air deflector that does not block the user's line of sight, that is, to determine the target gear of the air deflector 2.

[0070] It should also be noted that the process of determining whether the air deflector blocks the user's line of sight according to the geometric relationship of space here can be a real-time calculation process or a pre-calculation process. For example, the user's height obtained in real time and the shape of the air deflector at each gear that has been determined can be used to judge in real time whether the air deflector blocks the line of sight at each gear, and determine the target gear that does not block the line of sight. It can also be a pre-calculation to determine whether the air deflector blocks the line of sight in different user height ranges at each gear, and then compare the height range according to the user's height obtained in real time to directly determine the target gear that does not block the line of sight.

[0071] S140. Control the air deflector to adjust to the target gear.

[0072] This step is also controlled and executed by the processor. The processor can control the corresponding driving device to adjust the air deflector 2 to the target gear. Specifically, the processor can obtain the corresponding motion parameters of the driving device according to the target gear determined in the above step S130, and thus control the driving device to move with these motion parameters so that the air deflector 2 reaches the target gear.

[0073] The air deflector control method provided in the first embodiment of the present invention first obtains the user's body image; secondly, determines the user's height according to the user's body image; then determines the spatial position relationship between the user's height and the known height of the range hood device, and determines the target gear of the air deflector according to the spatial position relationship; wherein, at the target gear, the air deflector does not intersect with the line connecting the user's eyes and the cooking stove; finally, controls the air deflector to adjust to the target gear. Using the above method, it is possible to automatically control the air deflector to adjust to the matching gear according to the height characteristics of different users, make the air deflector adjust to a better shape, be able to more specifically perform automatic adjustment of the air deflector, avoid the air deflector blocking the user's line of sight, achieve a better smoke gathering effect, improve convenience, and improve the user's use experience.

[0074] Embodiment 2

[0075] Figure 3 As shown in the flowchart of a wind deflector control method provided by Embodiment 2 of the present invention, Embodiment 2 is optimized on the basis of the above embodiment. In this embodiment, further, the spatial position relationship between the user's height and the known height of the oil fume extraction device will be determined, and the target gear of the wind deflector will be determined according to the spatial position relationship. Further optimization is as follows:

[0076] Obtain the mapping relationship between the preset height range and the opening gear of the wind deflector;

[0077] Determine the target gear of the wind deflector according to the preset height range where the user's height is located.

[0078] For the content not detailed in this embodiment, please refer to Embodiment 1.

[0079] As Figure 3 shown, a wind deflector control method provided by Embodiment 2 of the present invention includes the following steps:

[0080] S310. Obtain the user's body image.

[0081] S320. Determine the user's height according to the user's body image.

[0082] S330. Obtain the mapping relationship between the preset height range and the opening gear of the wind deflector.

[0083] This step requires calculating the shape of the wind deflector in each opening gear in advance to determine whether the line of sight of the user is blocked in different height ranges. According to the pre-calculated results, the mapping relationship between the height range and the opening gear of the wind deflector is set, that is, when the user's height is in a certain height range, the opening gear that does not block the user's line of sight can be directly obtained according to the pre-established corresponding relationship.

[0084] S340. Determine the target gear of the wind deflector according to the preset height range where the user's height is located; wherein, the connection line between the wind deflector and the user's eyes and the cooking appliance does not intersect at the target gear.

[0085] This step is a process of determining the target gear of the wind deflector in real time according to the pre-established mapping relationship. It can be understood that due to the pre-established mapping relationship, this process does not need to perform spatial geometric operations in real time, and the determination of the target gear is faster and more effective, which can meet the usage requirements of users with different heights.

[0086] S350. Control the wind deflector to adjust to the target gear.

[0087] A wind deflector control method provided in the second embodiment of the present invention specifies the steps of determining the spatial position relationship by using the user's height and the height of the fume exhaust device, and then determining the target gear of the wind deflector according to the spatial position relationship. By using this method, the real-time calculation process can be simplified, the control efficiency of the wind deflector can be improved, the wind deflector gear matching the user's height can be provided in time, which helps to quickly drive the wind deflector in place and improve the response rate of the wind deflector.

[0088] On the basis of the technical solutions of the above embodiments, the embodiment of the present invention provides a specific implementation manner.

[0089] As a specific implementation manner of this embodiment, the above step S330, obtaining the mapping relationship between the preset height interval and the opening gear of the wind deflector, can be set as:

[0090] S331. Obtain at least one height threshold parameter and the opening gears of the wind deflector corresponding to at least two height intervals divided according to the height threshold parameter.

[0091] This process essentially simplifies the setting method of the preset height interval. By simply setting the height threshold parameter as the critical value for dividing each interval, different intervals can be divided for the height value, and the corresponding opening gears of the wind deflector can be set for the height intervals thus divided. Exemplarily, it can be set that the height threshold parameters include three, namely A, B, and C, and A < B < C. Correspondingly, the height intervals can be divided as: X ≤ A, A < X ≤ B, B < X ≤ C, X > C, where X is the user's height. Based on this preset height interval, different opening and closing angle gears can be set for the wind deflector. Taking specific opening and closing angles as an example, it can be set that when the height is in the interval of X ≤ A, the rotation angle of the wind deflector is α1; when the height is in the interval of A < X ≤ B, the rotation angle of the wind deflector is α2; when the height is in the interval of B < X ≤ C, the rotation angle of the wind deflector is α3; when the height is in the interval of X > C, the rotation angle of the wind deflector is α4. Among them, α1-α4 are the opening and closing angles calculated in advance that do not block the user's line of sight in the corresponding height intervals.

[0092] Therefore, the above step S340, determining the target gear of the wind deflector according to the preset height interval where the user's height is located, can specifically be set to include the following steps:

[0093] S341. Compare the user's height with the height threshold parameter to determine the height interval where the user's height is located.

[0094] S342. Determine the target gear of the corresponding wind deflector according to the height interval where the user's height is located.

[0095] Embodiment Three

[0096] Figure 4The following is a schematic flowchart of an air deflector control method provided in Embodiment 3 of the present invention. Embodiment 3 is optimized based on the above embodiments. In this embodiment, further, the following steps can be added:

[0097] Obtain an image of the cooking appliance;

[0098] Determine the height of the cookware based on the image of the cooking appliance.

[0099] Moreover, the step of determining the spatial position relationship between the two based on the user's height and the known height of the oil fume extraction device and determining the target gear of the air deflector can be further optimized as follows:

[0100] Determine the spatial position relationship among the user's height, the height of the cookware, and the known height of the oil fume extraction device, and determine the target gear of the air deflector according to the spatial position relationship.

[0101] For the content not detailed in this embodiment, please refer to Embodiment 1.

[0102] As Figure 4 shown, an air deflector control method provided in Embodiment 3 of the present invention includes the following steps:

[0103] S410. Obtain an image of the user's body posture.

[0104] S420. Determine the user's height based on the image of the user's body posture.

[0105] S430. Obtain an image of the cooking appliance.

[0106] S440. Determine the height of the cookware based on the image of the cooking appliance.

[0107] S450. Determine the spatial position relationship among the user's height, the height of the cookware, and the known height of the oil fume extraction device, and determine the target gear of the air deflector according to the spatial position relationship; wherein, at the target gear, the connection line between the air deflector and the user's eyes and the cooking appliance does not intersect.

[0108] In this embodiment, this step is actually a process of carefully calculating the spatial geometric relationship. It can be understood that in order to avoid the air deflector blocking the user's line of sight, it is necessary to calculate according to the shape of the air deflector, the position of the user's eyes, and the position of the cooking appliance. To a certain extent, the user's height in this step can represent the position of the user's eyes, or it can be converted into the position of the user's eyes. According to the height of the oil fume extraction device, the position and shape of the air deflector at each gear can be determined. Thus, by determining the position relationship among the user, the oil fume extraction device, and the cookware, the shape of the air deflector that does not block the line of sight can be calculated, and then the target gear of the air deflector can be determined.

[0109] S460. Control the air deflector to adjust to the target gear.

[0110] The air deflector control method provided in the third embodiment of the present invention specifies the steps of determining the spatial position relationship by using the user's height and the height of the oil fume suction device, and then determining the target gear of the air deflector according to the spatial position relationship. By using this method, the shape of the air deflector can be calculated relatively accurately, the opening gear of the air deflector that does not block the user's line of sight can be determined, more accurate automatic control can be provided for the user, and the user's line of sight can be prevented from being blocked by the air deflector.

[0111] On the basis of the technical solutions of the above embodiments, the embodiment of the present invention provides a specific implementation manner.

[0112] As a specific implementation manner of this embodiment, the above step S450 may be set as the following steps:

[0113] S451. Determine the relative height between the user and the oil fume suction device;

[0114] S452. Determine the relative height between the user's eyes and the oil fume suction device according to the relative height between the user and the oil fume suction device;

[0115] S453. Determine the relative height between the cookware and the oil fume suction device according to the height of the cookware;

[0116] S454. Determine the relative distance range and angle range between the user's eyes and the cookware according to the relative height between the user's eyes and the oil fume suction device and the relative height between the cookware and the oil fume suction device;

[0117] S455. Determine the target gear of the air deflector according to the relative distance range and angle range between the user's eyes and the cookware.

[0118] It should be noted that since the ratio of the user's eyes to the height is not a fixed value in actual situations, there may be errors when determining the position of the user's eyes according to the height. Using the range of the eyes as the standard for determining the target gear of the air deflector can make the obtained judgment result more accurate and effectively prevent the air deflector from blocking the user's line of sight. The sizes of the relative distance range and angle range between the user's eyes and the cookware here can be determined by experiments and are not limited too much here.

[0119] Considering that detailed geometric relationship calculations will be performed in this embodiment, in order to provide a more accurate and effective smoke collection effect, the embodiment of the present invention also provides another air deflector structure for a side suction type range hood. Among them, the air deflector includes a main air deflector, and also includes a sliding air deflector and / or a rotating air deflector. The sliding air deflector is slidably connected to the main air deflector, and the rotating air deflector is rotatably connected to the main air deflector or the sliding air deflector. Based on this, in the above step S450, determining the target gear of the air deflector according to the spatial position relationship may include:

[0120] S4501. Determine at least one of the target opening / closing angle position of the main air deflector, the target sliding distance position of the sliding air deflector, and the target rotation angle position of the rotating air deflector according to the spatial position relationship.

[0121] Figure 5 FIG. 4 is a schematic structural diagram of a side suction range hood provided in Embodiment 3 of the present invention. The following will be introduced with specific examples. The air deflector example includes a main air deflector 21, a sliding air deflector 22, and a rotating air deflector 23. The sliding air deflector 22 is slidably connected to the main air deflector 21, and the rotating air deflector 23 is rotatably connected to the sliding air deflector 22. Based on this, the air deflector positions determined in step S4501 are actually set with different positions according to the specific structure of the air deflector. Specifically, since the sliding air deflector 22 is provided on the main air deflector 21, the sliding distance of the sliding air deflector 22 relative to the main air deflector 21 determines the extension length of the entire air deflector, and is also an important factor for blocking the user's line of sight. Therefore, in addition to setting different positions according to the opening / closing angle of the main air deflector 21, different positions can also be set according to the sliding distance of the sliding air deflector 22. In addition, for the rotating air deflector 23 provided on the sliding air deflector 22, its rotation angle is also a factor affecting the blocking of the user's line of sight. Based on the structure of the rotating air deflector 23, different positions can also be set according to the rotation angle of the rotating air deflector 23. It can be understood that on the basis of the air deflector structure shown in Figure 5 FIG. 6 including three air deflector components, multiple positions can be divided according to the motion characteristics of the three air deflector components at the same time, or multiple positions can be divided according to the motion characteristics of at least one of the air deflector components. This is not limited here. Those skilled in the art can make various deformations to the air deflector position division scheme based on this, and all fall within the scope of the present embodiment. In addition, it should be added that the air deflector including the main air deflector 21, the sliding air deflector 22, and the rotating air deflector 23 shown in Figure 5 FIG. 8 is only an optional embodiment of the present invention. In specific design or application, it is optional to only provide one of the sliding air deflector 22 and the rotating air deflector 23 on the main air deflector 21.

[0123] Figure 6 FIG. 19 is a specific air deflector control flow chart provided in Embodiment 4 of the present invention. The following will introduce the specific control logic of the air deflector in the actual application scenario with reference to Figure 6 FIG. 21. First, referring to the air deflector structure of the side suction range hood shown in Figure 5 FIG. 23, a camera sensor is provided on the control board of the main air deflector ( Figure 5(not shown in the figure) can scan and irradiate the user through the front end of the main air deflector to collect and identify the user's body posture data. The control board simultaneously provides data signals to the driving device, and the driving device performs corresponding movements according to the received different data signals.

[0124] When the user turns on the range hood and presses the power button, the camera sensor starts to work. First, it identifies the relative height between the cookware and the range hood. After the main air deflector is opened in place, it scans and identifies the user's body posture data to obtain the user's height parameter. After obtaining the height parameter, it analyzes the relative height value between the range hood and the user, and then the control board calculates to obtain the corresponding range of the user's eye height, the relative distance range between the eyes and the cookware, and the relative angle range between the eyes and the cookware. After determining the parameter range, it adjusts the positions of the slidable air deflector and the rotatable air deflector according to the preset parameters of the driving device, and defines the function gear of the driving device at this time.

[0125] To simplify the parametric design of the control board: The control board determines the user's height range into three gears according to the obtained data such as eyes and cookware, divided into A, B, and C, corresponding to three height data respectively (for example: 160 / 170 / 180).

[0126] To simplify the preset parameter positions of the driving device: The stroke of the driving device is set to 4 gears, corresponding to the relative angles α1, α2, α3, α4 between the rotatable air deflector and the slidable air deflector respectively (α1 < α2 < α3 < α4, α1 = 0, α4 = β).

[0127] After the camera identifies the parameters and the control board determines the parameter range, the position adjustment is divided into 4 gears. ① When the user's height X ≤ A, the telescopic rod of the driving device moves to the end of the lowest stroke of the slidable air deflector, and the relative angle between the rotatable air deflector and the slidable air deflector becomes α1; ② When A < user's height X ≤ B, the telescopic rod of the driving device moves until the relative angle between the rotatable air deflector and the slidable air deflector becomes α2; ③ When B < user's height X ≤ C, the telescopic rod of the driving device moves until the relative angle between the rotatable air deflector and the slidable air deflector becomes α3; ④ When the user's height X > C, the telescopic rod of the driving device moves until the relative angle between the rotatable air deflector and the slidable air deflector becomes α4.

[0128] Example: The factory settings for the three heights are 160 / 170 / 180. When a certain user uses it, the sensor identifies the height as 165 (X = 165). It is judged that X is in the range of 160 < 165 ≤ 170. After the driving device receives the electrical signal from the control board, it operates to the second gear by itself, pushes the slidable air deflector to the maximum position, and stops after running the rotatable air deflector to a relative angle of α2 with the slidable air deflector.
