[0108] Embodiment 1

[0109] The embodiments of the present disclosure provide an oil fume treatment device 100. The oil fume treatment device 100 can be all types of devices with oil fume treatment functions, such as overhead range hoods, side-suction range hoods, top-suction range hoods, and near-suction range hoods. All types of devices with oil fume treatment functions are within the protection scope of the embodiments of the present disclosure. Taking the near-suction range hood as an example, the structure of the oil fume treatment device 100 will be described in the embodiments of the present disclosure.

[0110] As Figures 1 to 2 shown, the embodiments of the present disclosure disclose an oil fume treatment device 100. The oil fume treatment device 100 includes a main chassis 50, a smoke collecting hood 10, and a wind guiding plate 20. The main chassis 50 includes a chassis main body. The chassis main body is communicated with the smoke collecting hood 10. A fan can be arranged in the chassis main body or in the smoke collecting hood 10. The smoke collecting hood 10 has a main air inlet 11. The wind guiding plate 20 can switch between a first position where the main air inlet 11 is blocked and a second position where the main air inlet 11 is opened. When the wind guiding plate 20 is in the first position, the wind guiding plate 20 can achieve a good blocking effect on the main air inlet 11, and can prevent the oil fume smell in the smoke collecting hood 10 from spreading into the room. When the wind guiding plate 20 is in the second position, the fan works to generate negative pressure inside the chassis main body, and the oil fume outside the oil fume treatment device 100 can enter the smoke collecting hood 10 and the main chassis 50 through the main air inlet 11 and be discharged to the outside.

[0111] An air outlet is provided on the chassis main body. After the oil fume passes through the overall filtration of the oil fume treatment device 100, relatively clean gas is formed, and the relatively clean gas is discharged from the air outlet. Among them, the smoke collecting hood 10 can achieve a good effect of converging and concentrating the oil fume, facilitating a large amount and sufficient entry of the external oil fume into the subsequent main chassis 50.

[0112] As Figure 1 and Figure 2 shown, the oil fume treatment device 100 further includes a temperature sensing module 31. The temperature sensing module 31 can detect the temperature of the area to be measured, and the detected temperature of the area to be measured is fed back to the control mechanism of the oil fume treatment device 100 in real time. The control mechanism can achieve precise and rapid control of the oil fume treatment device 100 according to the detected temperature of the area to be measured.

[0113] As Figure 1 and Figure 2 shown, the current oil fume treatment device 100 further includes an operation component 32. Among them, the temperature sensing module 31 is arranged on the smoke collecting hood 10. The operation component 32 is used to supply power to the temperature sensing module 31 and transmit feedback instructions. The operation component 32 is arranged on the air deflector 20 to facilitate the user to operate the operation component 32 conveniently. The temperature sensing module 31 and the operation component 32 are independently arranged, and the temperature sensing module 31 and the operation component 32 are far apart. A long transmission line 70 is required to connect the temperature sensing module 31 and the operation component 32. After adding the transmission line 70, there will be a problem of signal transmission deviation in the signal transmission between the temperature sensing module 31 and the operation component 32 because there is one more transmission path. In addition, since the routing of the transmission line 70 on the smoke collecting hood 10 and the air deflector 20 is complex, when the problematic transmission line 70 needs to be replaced, the entire oil fume treatment device 100 needs to be disassembled, resulting in high maintenance difficulty and high maintenance cost of the transmission line 70.

[0114] To solve the above problems, as Figure 3 and Figure 4 shown, the oil fume treatment device 100 of the embodiment of the present disclosure includes an operation mechanism 30. The operation mechanism 30 includes a housing 33, a temperature sensing module 31 and an operation component 32. An opening is formed on the housing 33. The temperature sensing module 31 and the operation component 32 are both arranged inside the housing 33. The temperature sensing module 31 can detect the temperature of the area to be measured through the opening. The operation component 32 is communicatively connected with the temperature sensing module 31. The temperature sensing module 31 and the operation component 32 are arranged in the same area and inside the housing 33. The temperature sensing module 31 and the operation component 32 are close to each other, and the operation component 32 and the temperature sensing module 31 can be directly docked without additionally setting a transmission line 70 as Figure 1 and Figure 2 shown. Therefore, the signal transmission of the temperature sensing module 31 can effectively reduce the transmission deviation. In addition, since the long transmission line 70 with complex routing in the smoke collecting hood 10 and the air deflector 20 is cancelled, the overall disassembly of the oil fume treatment device 100 caused by repairing the transmission line 70 can be avoided, effectively reducing the maintenance difficulty and maintenance cost of the oil fume treatment device 100. It should be noted that the temperature of the area to be measured can be the temperature of cookware, cooking appliances, etc. It should be noted that the opening can be arranged forward, downward or forward and downward.

[0115] As Figures 3 to 6As shown, the oil fume treatment device 100 also includes a connecting rod assembly 40, and the connecting rod assembly 40 includes a connecting rod body and a linear drive mechanism 43. The air guide plate 20 is transmission-connected to the smoke hood 10 through the connecting rod body. One end of the linear drive mechanism 43 is rotationally connected to the smoke hood 10, and the other end of the linear drive mechanism 43 is rotationally connected to the air guide plate 20. When the linear drive mechanism 43 is working, the connecting rod body includes a plurality of connecting rods that cooperate with each other. The linear drive mechanism 43 can drive each connecting rod to rotate and displace, and the connecting rod body drives the air guide plate 20 to perform a flipping motion relative to the smoke hood 10.

[0116] like Figure 3 and Figure 5 As shown, the fume hood 10 is also provided with an auxiliary air inlet 12, which is arranged above the main air inlet 11. When the overall oil fume is large, the main air inlet 11 and the auxiliary air inlet 12 can be opened at the same time, thereby achieving a large amount of absorption effect on the oil fume. The oil fume treatment device 100 can achieve a rapid recovery effect on a large amount of oil fume.

[0117] like Figure 3 As shown, the temperature sensing module 31 is arranged above and in front of the air guide plate 20. The temperature sensing module 31 can form a conical detection area S. When the air guide plate 20 is opened, interference with the detection area S may occur. The air guide plate 20 may block the detection of the temperature sensing module 31, thereby affecting the temperature sensing module 31's accurate detection of the temperature of the area to be measured.

[0118] To solve the above problems, Figure 7 and Figure 8 As shown, the embodiment of the present disclosure provides a design method of an oil fume treatment device 100, the design method comprising:

[0119] S1: Obtaining the setting position of the temperature sensing module 31 and determining the detection area S formed by the temperature sensing module 31;

[0120] S2: Design the air deflector movement trajectory T of the air deflector 20 导 , so that the air guide plate 20 is always located outside the detection area S.

[0121] Through the above-mentioned design method, under the premise that the setting position of the temperature sensing module 31 is determined, by adjusting the design method of the air guide plate 20, it is ensured that the air guide plate 20 is always located outside the detection area S regardless of the state of the air guide plate 20, so as to avoid the problem of interference between the air guide plate 20 and the detection area S during the opening or closing process, and prevent the air guide plate 20 from blocking the detection of the temperature sensing module 31, thereby ensuring the temperature sensing module 31 to accurately detect the temperature of the measured area.

[0126] S22: Obtain the movement trajectory T of the air deflector 20; 导 ;

[0127] S23: Compare the movement trajectory T of the air deflector 20 导 with the detection area S: If the movement trajectory T of the air deflector 20 导 interferes with the detection area S, return to step S21; If the movement trajectory T of the air deflector 20 导 does not interfere with the detection area S, then perform S24;

[0128] S24: Take the preset design parameters of the connecting rod assembly 40 and the air deflector 20 as the actual design parameters of the connecting rod assembly 40.

[0129] By dynamically adjusting the design parameters of the input connecting rod assembly 40 and the air deflector 20, it is possible to quickly and accurately design the connecting rod assembly 40 and the air deflector 20 that satisfy that the movement trajectory T of the air deflector 20 导 does not interfere with the detection area S, avoid the problem that the air deflector 20 interferes with the detection area S during the opening or closing process, prevent the air deflector 20 from blocking the detection of the temperature sensing module 31, and ensure the accurate detection of the temperature of the area to be measured by the temperature sensing module 31.

[0130] In an optional embodiment, the preset design parameters include: the connection position of the connecting rod assembly 40 and the smoke collecting hood 10, the connection position of the connecting rod assembly 40 and the air deflector 20, the lengths of the respective connecting rods in the connecting rod assembly 40, the connection positions between the connecting rods in the connecting rod assembly 40, and / or the size of the air deflector 20. Through the comprehensive adjustment of various parameters, it is possible to quickly and accurately design the connecting rod assembly 40 and the air deflector 20 that satisfy that the movement trajectory T of the air deflector 20 导 does not interfere with the detection area S, so as to achieve the matching of different models of the oil fume treatment device 100.

[0131] Such as Figure 8As shown, the temperature sensing module 31 is arranged above and in front of the air guide plate 20. The temperature sensing module 31 can form a conical detection area S with a small top and a large bottom. In the aforementioned scenario, when the air guide plate 20 is moving, the lower end E of the air guide plate 20 will always be closest to the detection area S. Therefore, as long as the lower end E of the air guide plate 20 does not interfere with the detection area S, the air guide plate movement trajectory T of the air guide plate 20 can be guaranteed. 导 It does not interfere with the detection area S. Therefore, in the embodiment of the present disclosure, the air guide plate motion trajectory T of the air guide plate 20 is obtained. 导 The specific step is to obtain the motion trajectory T of the lowermost end E of the air guide plate 20. E , which can simplify the analysis of the overall movement of the wind deflector 20 and can meet the bottom end movement trajectory T E The connecting rod assembly 40 and the air guide plate 20 that do not interfere with the detection area S are designed quickly and accurately.

[0132] In an optional embodiment, if Figures 10 to 11 As shown, the connecting rod assembly 40 includes a first connecting rod 41, a second connecting rod 42 and a linear drive mechanism 43, the first connecting rod 41 is rotatably connected to the smoke hood 10 through point A, the first connecting rod 41 is rotatably connected to the air guide plate 20 through point B, the second connecting rod 42 is rotatably connected to the air guide plate 20 through point C, the second connecting rod 42 is rotatably connected to the smoke hood 10 through point D, the body of the linear drive mechanism 43 is rotatably connected to the smoke hood 10, the output end of the linear drive mechanism 43 is rotatably connected to the first connecting rod 41, and the lowermost end of the air guide plate 20 is point E. Specifically, the smoke hood 10 includes a fixed seat 13, the first connecting rod 41 and the second connecting rod 42 are both rotatably connected to the fixed seat 13, the fixed seat 13 can achieve stable support for the first connecting rod 41 and the second connecting rod 42, and the fixed seat 13 can also achieve a relatively stable support effect for the air guide plate 20.

[0133] like Figure 6 As shown, the first connecting rod 41 and the second connecting rod 42 form a connecting rod module, and the oil fume treatment device 100 also includes a connecting rod 60. The connecting rod modules are arranged in two groups, and the two groups of connecting rod modules are fixedly connected by the connecting rod 60. Only one group of linear drive mechanism 43 is arranged, and the linear drive mechanism 43 is transmission-connected to one of the connecting rod modules. Through the arrangement of the connecting rod 60, synchronous driving of the two groups of connecting rod modules can be achieved, and the structure is simple and easy to operate.

[0134] like Figures 10 to 11As shown in the figure, it is defined that the included angle between the extension line of AB and AD is the second included angle θ2, the included angle between BC and AD is the third included angle θ3, the length of AD is the first length L1, the length of AB is the second length L2, the length of BC is the third length L3, and the length of CD is the fourth length L4; a coordinate system is established with AD as the vertical axis, the direction perpendicular to AD as the horizontal axis, and A as (0, 0).

[0135] Obtain the air deflector movement trajectory T of the air deflector 20 导 The steps include:

[0136] Obtain the first relationship among the second included angle θ2, the third included angle θ3, the first length L1, the second length L2, the third length L3, and the fourth length L4: θ2 = F(θ3, L1, L2, L3, L4);

[0137] Obtain the abscissa X of point E in the coordinate system E The first formula of and the ordinate Y of point E E The second formula, where X E = F(θ2, θ3, L1, L2, L3, L4), Y E = T(θ2, θ3, L1, L2, L3, L4);

[0138] Substitute the preset first length L1, second length L2, third length L3, and fourth length L4 into the first relationship, the first formula, and the second formula, and the corresponding θ3, X E and Y E corresponding to θ2 can be obtained, and the corresponding θ3, X E and Y E corresponding to θ2 form a parameter group;

[0139] Fit multiple groups of parameter groups to obtain the lowest end movement trajectory T of the lowest end E of the air deflector 20 E :

[0140]

[0141] Through the above method, designers only need to give the preset first length L1, second length L2, third length L3, and fourth length L4. Through the fitting effect of multiple groups of parameter groups, the accurate acquisition of the lowest end movement trajectory T E can be realized. Designers only need to adjust different preset first length L1, second length L2, third length L3, and fourth length L4 according to needs, and then can quickly and accurately obtain the lowest end movement trajectory T E .

[0142] Exemplarily, according to this coordinate system, points B and C are two variable points, and the coordinates of point B are (XB , Y B ), the coordinates of point C are (X C , Y C ). By rotating point B around point A and point C around point D, we can obtain:

[0143] X B = L2 * SIN(θ2);

[0144] Y B = L2 * COS(θ2);

[0145] X C = L4 * SIN(θ4);

[0146] Y C = L1 + L4 * COS(θ4);

[0147] According to the closed-loop vector equation of the four-bar linkage:

[0148] L2 * COS(θ2) + L3 * COS(θ3) = L1 + L4 * COS(θ4);

[0149] L2 * SIN(θ2) = L4 * SIN(θ4) + L3 * SIN(θ3);

[0150] According to the above formulas, we can obtain:

[0151] COS(θ4) = [L3 * COS(θ3) + L2 * COS(θ2) - L1] / L4;

[0152] SIN(θ4) = [L2 * SIN(θ2) - L3 * SIN(θ3)] / L4;

[0153] By eliminating θ4 through [COS(θ4)]^2 + [SIN(θ4)]^2 = 1, we can obtain the first relational expression:

[0154] L4 2 = L1 2 + L2 2 + L3 2 + 2 * L2 * L3 * COS(θ2) * COS(θ3) - 2 * L1 * L2 * COS(θ2) - L1 * L3 * COS

[0155] (θ3) - 2 * L2 * L3 * SIN(θ2) * SIN(θ3);

[0156] Based on the first relational expression, when the dimensions of the first length L1, the second length L2, the third length L3, and the fourth length L4 are determined, a functional relational expression between θ2 and θ3 can be obtained, and then the numerical relationship between θ2 and θ3 can be calculated through the Newton iteration method.

[0157] Example: When L1 = 40, L2 = 120, L3 = 75, L4 = 86, substituting into the first relational expression gives:

[0158] 7396 = 1600 + 14400 + 5625 + 17520 * COS(θ2) * COS(θ3) - 9600 * COS(θ2) - 6000 * COS(θ3) - 18000 * SIN(θ2) * SIN(θ3);

[0159] That is:

[0160] 14229 + 17520 * COS(θ2) * COS(θ3) - 9600 * COS(θ2) - 6000 * COS(θ3) - 18000 * SIN(θ2) * SIN(θ3) = 0;

[0161] Furthermore, through calculation by the Newton - Raphson method, it can be obtained that:

[0162] When θ2 = 20°, θ3 = 3.5°;

[0163] When θ2 = 30°, θ3 = 7.1°;

[0164] When θ2 = 40°, θ3 = 10.6°;

[0165] When θ2 = 50°, θ3 = 14.1°;

[0166] When θ2 = 60°, θ3 = 17.7°;

[0167] When θ2 = 70°, θ3 = 21.5°;

[0168] When θ2 = 80°, θ3 = 25.6°;

[0169] When θ2 = 90°, θ3 = 30.2°;

[0170] When θ2 = 100°, θ3 = 35.2°;

[0171] As Figures 10 to 11 shown, next is to define the coordinates of point E at the lowermost end of the air deflector 20:

[0172] According to the actual design requirements of the connecting rod assembly 20, the dimension of point B from the plane of the air deflector 20 is a design value, defined as point J in the coordinate system, and BJ is defined as a constant b here. According to the actual width of the connecting rod and the rotation requirements, this constant b will not change. At the same time, based on the oil fume treatment device 100 of the embodiment of the present disclosure, the overall dimension of the air deflector 20 is a design value, and then the length JE can also be used as a design value, which can be adjusted and can be initially defined as c. When subsequent calculations are carried out, c is considered as a constant. Draw an auxiliary line parallel to the X-axis through point B, and this auxiliary line intersects with the straight line where the air deflector 20 is located at point P, and we can get:

[0173] EP = c - b * tan(θ3);

[0174] X E -X B = b / COS(θ3) + EP * SIN(θ3);

[0175] Y E -Y B = EP * COS(θ3);

[0176] It can be solved that:

[0177] The first formula: X E = X B + b / COS(θ3) + EP * SIN(θ3) = L2 * SIN(θ2) + b / COS(θ3) + [c - b * tan(θ3)] * SIN(θ3);

[0178] The second formula: Y E = Y B + EP * COS(θ3) = L2 * COS(θ2) + [c - b * tan(θ3)] * COS(θ3);

[0179] Based on this, a system of equations for the coordinates (X E , Y E ) of point E can be obtained.

[0180] At the same time, according to the overall structure of the oil fume treatment device 100 of the embodiment of the present disclosure, the initial rod lengths of the connecting rod assembly 20 are designed. After substituting the preset first length L1, second length L2, third length L3, and fourth length L4 into the first relational expression, the numerical change relationship between θ2 and θ3 can be obtained, and then substituting it into the first formula and the second formula, the movement trajectory curve of point E in this coordinate system can be obtained.

[0181] Example: When L2 = 120, b = 15, c = 74,

[0182] X E= L2 * SIN(θ2) + b / COS(θ3) + [c - b * tan(θ3)] * SIN(θ3) = 120 * SIN(θ2)

[0183] + 15 / COS(θ3) + [74 - 15tan(θ3)] * SIN(θ3);

[0184] Y E = L2 * COS(θ2) + [c - b * tan(θ3)] * COS(θ3) = 120 * COS(θ2) + [74 - 15tan(θ

[0185] 3)] * COS(θ3);

[0186] When θ2 = 20°, θ3 = 3.5°, X can be obtained as E = 60.6, Y E = 185.7, and then according to the coordinate system situation, change Y E to -185.7;

[0187] When θ2 = 30°, θ3 = 7.1°, X can be obtained as E = 84.2, Y E = 175.4, and then according to the coordinate system situation, change Y E to -175.4;

[0188] When θ2 = 40°, θ3 = 10.6°, X can be obtained as E = 105.6, Y E = 161.8, and then according to the coordinate system situation, change Y E to -161.8;

[0189] When θ2 = 50°, θ3 = 14.1°, X can be obtained as E = 124.5, Y E = 145.2, and then according to the coordinate system situation, change Y E to -145.2;

[0190] When θ2 = 60°, θ3 = 17.7°, X can be obtained as E = 140.8, Y E = 125.8, and then according to the coordinate system situation, change Y E to -125.8;

[0191] When θ2 = 70°, θ3 = 21.5°, X can be obtained as E = 153.9, Y E = 104.3, and then according to the coordinate system situation, change Y E to -104.3;

[0192] When θ2 = 80°, θ3 = 25.6°, X can be obtained as E = 163.7, and Y E = 80.9. Then, according to the coordinate system situation, Y E is changed to -80.9;

[0193] When θ2 = 90°, θ3 = 30.2°, X can be obtained as E = 170.2, and Y E = 56.3. Then, according to the coordinate system situation, Y E is changed to -56.3;

[0194] When θ2 = 100°, θ3 = 35.2°, X can be obtained as E = 173.1, and Y E = 30.9. Then, according to the coordinate system situation, Y E is changed to -30.9;

[0195] According to the above results, the lowest movement trajectory T of the lowest end of the air deflector 20 can be fitted E .

[0196] Through the above method, designers only need to give the preset first length L1, second length L2, third length L3, and fourth length L4. Through the fitting effect of multiple parameter groups, the accurate acquisition of the lowest movement trajectory T E can be achieved. Designers only need to adjust the different preset first length L1, second length L2, third length L3, and fourth length L4 according to needs, and then can quickly and accurately obtain the lowest movement trajectory T E . By adjusting the preset first length L1, second length L2, third length L3, and fourth length L4, the lowest movement trajectories T of the lowest ends E of different air deflectors 20 can be fitted E . By adjusting the preset first length L1, second length L2, third length L3, and fourth length L4, the adjustment of the lowest movement trajectory T of the lowest end E of the air deflector 20 can be achieved E .

[0197] In an optional embodiment, the steps of S23 include:

[0198] Obtain the formula of the boundary line H on the side of the detection area S close to the air deflector 20: Y' = K H *X' + h'; where K H is the slope of the boundary line H, and h' is the intercept of the boundary line H;

[0199] According to the lowest movement trajectory T of the lowest end E of the air deflector 20 E , the lowest movement trajectory T EThe slope K(θ2) at any tangent point above;

[0200] Let K H = K(θ2), and the θ2 at the tangent point can be obtained;

[0201] Substitute θ2 into the lowest - end movement trajectory T of the lowest - end E of the air deflector 20 E , and X E and Y E can be obtained;

[0202] Substitute X E into the formula of the boundary line H, and Y' can be obtained;

[0203] Compare Y E with Y':

[0204] When Y E > Y', it means that the lowest - end movement trajectory T of the lowest - end E of the air deflector 20 E does not intersect with the boundary line H, and the air deflector movement trajectory T of the air deflector 20 导 does not interfere with the detection area S;

[0205] When Y E = Y', it means that the lowest - end movement trajectory T of the lowest - end E of the air deflector 20 E intersects with the boundary line H, and the air deflector movement trajectory T of the air deflector 20 导 does not interfere with the detection area S;

[0206] When Y E < Y', it means that the lowest - end movement trajectory T of the lowest - end E of the air deflector 20 E has two intersection points with the boundary line H, and the air deflector movement trajectory T of the air deflector 20 导 interferes with the detection area S.

[0207] Through the above steps, it is possible to quickly judge whether the lowest - end movement trajectory T E interferes with the detection area S.

[0208] Exemplarily, synchronously place the position of the temperature - sensing module 31 on the aforementioned coordinate system. Point W is the emission point of the temperature - sensing module 31, and point G is the center point of the bottom of the cookware. To ensure that the irradiation of the temperature - sensing module 31 can cover the cookware, it is most appropriate to use the connection line between the emission point W of the temperature - sensing module 31 and the center point G of the bottom of the cookware as the central axis of the infrared emission area. The irradiation area of the temperature - sensing module 31 is a conical shape with the central axis as the reference, and the cone angle is the emission field angle of the temperature - sensing module 31. The two outermost projection lines projected onto the two - dimensional plane coordinate system are the irradiation boundary lines of the temperature - sensing module 31. The irradiation boundary line close to the lowest - end movement trajectory T E is the boundary line H.

[0209] Set the coordinates of point W as (X W , Y W ), the coordinates of point G as (X G , Y G ), α is the emission field of view angle of the temperature sensor module 31, and the central axis WG is Y = K WG *X + h;

[0210] First, we can obtain the slope K of the central axis WG =(Y W -Y G ) / (X W -X G ), and the boundary line H is defined as: Y' = K H *X' + h', according to the straight line rotation slope formula:

[0211] K'=(K + tan(θ)) / (1 - K*tan(θ)) we can get:

[0212] Y'=(K WG +tan(α / 2)) / (1 - K WG *tan(α / 2));

[0213] That is: Y'=(K WG +tan(α / 2)) / (1 - K WG *tan(α / 2))*X' + h', and at the same time Y' also passes through point W, so h' can be obtained, and the straight line equation of the boundary line is thus defined.

[0214] First, it can be assumed that the lowest movement trajectory T E is at the tangent point position with the boundary line H. If there is a tangent point, first, the slope of a certain point on the lowest movement trajectory T E should be equal to the boundary line H of the boundary line, that is: d(Y E ) / d(X E ) = K H , and further, the tangent point slope is also a functional relationship about θ2:

[0215] {d(Y E ) / d(θ2)} / {d(X E ) / d(θ2)} = K(θ2), K(θ2) = K H ;

[0216] According to K(θ2) = K H , the value of θ2 at the tangent point can be obtained, and substituting it back inversely can obtain the position of point E at this time. Then, according to the fact that point E is also on the boundary line H, substituting it into the boundary line function to verify whether the tangent point exists.

[0217] Substitute Y ECompare with Y':

[0218] When Y E > Y', it is the lowest movement trajectory T of the lowest end E of the air deflector 20 E does not intersect with the boundary line H, and the air deflector movement trajectory T of the air deflector 20 导 does not interfere with the detection area S;

[0219] When Y E = Y', it is the lowest movement trajectory T of the lowest end E of the air deflector 20 E intersects with the boundary line H, and the air deflector movement trajectory T of the air deflector 20 导 does not interfere with the detection area S;

[0220] When Y E < Y', it is the lowest movement trajectory T of the lowest end E of the air deflector 20 E has two intersection points with the boundary line H, and the air deflector movement trajectory T of the air deflector 20 导 interferes with the detection area S.

[0221] Exemplarily, based on the foregoing solution of the oil fume treatment device 100, substituting into the coordinate system, the coordinates of the emission point W of the temperature sensing module 31 are designed to be (219.2, 158.4), the coordinates of the center G of the pot bottom are (191, -491.4), the emission field of view angle α of the temperature sensing module 31 = 20°, and the boundary line H is rotated clockwise around the central axis, and tan(-10°) is used for calculation;

[0222] We can first obtain K WG =(Y W - Y G ) / (X W - X G )=(158.4 + 491.4) / (219.2 - 191)=23.04;

[0223] K H =(K WG + tan(α / 2)) / (1 - K WG * tan(α / 2))=(23.04 + tan(-10°)) / (1 - 23.04 * tan(-

[0224] 10°)) = 4.52;

[0225] Then substitute the coordinates of point W to find h', h' = Y W - X W * K H = 158.4 - 4.52 * 219.2 = -832.384;

[0226] That is, Y' = 4.52 * X' - 832.384;

[0227] Then, according to the derivative {d(Y E ) / d(θ2)} / {d(X E ) / d(θ2)} = K H = 4.52;

[0228] [-120 * sin(θ2) + [74 - 15 * tan(θ3)] * COS(θ3)] / [120 * cos(θ2) + 15 / COS(θ3) + [74 - 15 * tan(θ3)] * SIN(θ3)] = 4.52;

[0229] Calculated according to the Newton - Raphson method, θ2 = 86.9° is obtained;

[0230] Substituting θ2 into the coordinates of point E, X E = 168.5, Y E = 64.3. Then, according to the coordinate system situation, change Y E to - 64.3. Then substitute the coordinate value of X E into the boundary line H, and Y' = - 70.76 is obtained at this time. At this time, Y E > Y', so the lowest - end movement trajectory T E does not interfere with the boundary line H.

[0231] In an alternative embodiment, it is also possible to use the mapping method to respectively draw the lowest - end movement trajectory T E of the lowest - end point E of the air deflector 20 and the boundary line H, and determine whether the lowest - end movement trajectory T E interferes with the detection area S by observing whether the lowest - end movement trajectory T E and the boundary line H cross.

[0232] In an alternative embodiment, as Figure 3 and Figure 12 shown, an auxiliary air inlet 12 is provided on the smoke hood 10. The auxiliary air inlet 12 is located above and in front of the air deflector 20, and the auxiliary air inlet 12 is also located behind the temperature - sensing module 31. The center line M of the auxiliary air inlet 12 extends in the vertical direction, and the center line M and the detection area S form a contour area Q on the side away from the air deflector 20; the steps of designing the air deflector movement trajectory T 导 of the air deflector 20 so that the air deflector 20 is always outside the detection area S include:

[0233] Designing the air deflector movement trajectory T 导 of the air deflector 20 so that the air deflector 20 is always outside the contour area Q.

[0234] Through the above design method, it can be ensured that the auxiliary air inlet 12 still has the function of sucking smoke when the air deflector 20 is in the open state, so as to ensure that the oil fume treatment device 100 always has a good oil fume suction effect.

[0235] Embodiment III

[0236] As Figure 13 shown, the present disclosure embodiment provides a design method for an oil fume treatment device 100. This design method has the same general concept as the design method of Embodiment I. This design method includes:

[0237] Obtain the air deflector movement trajectory T of the air deflector 20 导 ;

[0238] Design the preset position of the temperature sensing module 31 and determine the detection area S formed by the temperature sensing module 31, so that the air deflector 20 is always outside the detection area S.

[0239] Through the above design method, when the air deflector movement trajectory T of the air deflector 20 导 is under a certain premise, by adjusting the design method of the temperature sensing module 31, it can be ensured that the air deflector 20 is always outside the detection area S regardless of any state, which can avoid the problem that the air deflector 20 interferes with the detection area S during the opening or closing process, prevent the air deflector 20 from blocking the detection of the temperature sensing module 31, and ensure the accurate detection of the temperature of the area to be measured by the temperature sensing module 31.

[0240] Embodiment IV

[0241] As Figure 14 shown, the present disclosure embodiment provides a design method for an oil fume treatment device 100. This design method is basically the same as the design method of Embodiment III. The design method of the present disclosure embodiment is a further refinement of the design method of Embodiment III. This design method includes:

[0242] S11': Input the design parameters of the link assembly 40 and the air deflector 20;

[0243] S12': Obtain the air deflector movement trajectory T of the air deflector 20 导 .

[0244] Through the design parameters of the link assembly 40 and the air deflector 20, an accurate air deflector movement trajectory T of the air deflector 20 can be obtained 导 , and according to this accurate air deflector movement trajectory T 导 the position of the temperature sensing module 31 can be reasonably arranged adaptively.

[0245] In an alternative embodiment, the design parameters include: the connection position of the link assembly 40 and the smoke collecting hood 10, the connection position of the link assembly 40 and the air deflector 20, the lengths of the respective links in the link assembly 40, the connection positions between the links in the link assembly 40, and / or the dimensions of the air deflector 20. Through the comprehensive adjustment of various parameters, the design of the air deflector 20 that meets different usage scenarios can be achieved, thereby improving the adaptability of the air deflector 20 to different oil fume treatment devices 100.

[0246] It should be noted that, regarding the specific acquisition of the movement trajectory T of the air deflector 导 , the relevant methods and means in Embodiment 2 can be referred to, and the embodiments of the present disclosure will not be elaborated further.

[0247] S21': Compare the movement trajectory T of the air deflector 20 导 with the detection area S:

[0248] If the movement trajectory T of the air deflector 20 导 interferes with the detection area S, then proceed to S22';

[0249] If the movement trajectory T of the air deflector 20 导 does not interfere with the detection area S, then proceed to S23';

[0250] S22': Adjust the preset setting position of the temperature sensing module 31 and return to S21';
