For example, in the range hood disclosed in chinese utility model patent with an authorization publication No. CN205747066U (application No. 201620546798.4), the range hood utilizes an oil smoke sensor to detect the concentration of oil smoke and adjusts the rotation speed of the fan according to the concentration of oil smoke. However, when the oil smoke concentration is detected, the installation position of the oil smoke sensor is fixed, so that the randomness of the dissipation direction of the oil smoke is strong due to the influence of external factors, and the oil smoke distribution in different areas is uneven relative to the smoke inlet of the range hood. Therefore, even under the condition of the same oil smoke concentration, the detected concentration data has large difference due to different concentrations dissipated to the oil smoke sensor, and further, the adjustment of the rotating speed of the fan has errors.

The specific working method of the intelligent range hood for adjusting the opening degree of each opening 31 according to the concentration of the oil smoke is as follows.
S1, the openings 31 are initially numbered as openings No. 1, No. 2, No. 31, No. … …, No. i, No. … …, and No. n, respectively, 31. n is the total number of the openings 31, and n is more than or equal to 2.
S2, according to the position condition of each opening 31, estimating the size of the risk of smoke leakage of the opening 31, and correspondingly initializing a first regulating coefficient k of the air intake of each opening 31, wherein the first regulating coefficient k (i) of the air intake of the No. i opening 31 is recorded as k (i). The larger the risk of smoke leakage, the larger the first regulating coefficient k of the intake of the opening 31, for example, the greater the intake regulating coefficient of the opening 31 near the edge of the smoke collecting cover 3 of the range hood than the intake regulating coefficient of the opening 31 near the middle of the smoke collecting cover 3 of the range hood, generally, the first regulating coefficient of the intake of the opening 31 near the edge of the smoke collecting cavity of the range hood is greater than 1, and the intake regulating coefficient of the opening 31 near the middle of the smoke collecting cavity of the range hood is less than 1. These intake air first adjustment coefficients k (i) are stored in a control circuit board of the range hood.
In addition, a second regulating coefficient p of the intake air quantity of each opening 31 is stored in the control circuit board of the range hood, wherein 0< p < ═ 1. The second regulating coefficient p of the intake air volume of each opening 31 corresponds not to the position of the opening 31 but to the intake air volume of the opening 31 after the first opening adjustment, wherein the smaller the theoretical intake air volume of the opening 31 after the first opening adjustment, the smaller the regulating coefficient p, and the regulating coefficient p of the maximum theoretical intake air volume of the opening 31 after the first opening adjustment is 1.
S3, according to the oil smoke data condition of the air inlet acquired by the oil smoke concentration detection unit 2, the initial theoretical air intake F0 of each opening 31 is preliminarily calculated, and the initial theoretical air intake of the opening 31 with the number i is recorded as F0 (i). The more the oil smoke below the opening 31, the larger the initial theoretical intake of the air inlet in the area, until the maximum value is allowed, and conversely, the less the oil smoke below the opening 31, the smaller the initial theoretical intake of the opening 31, until the minimum value is allowed.
And S4, according to the position condition of each opening 31, performing first adjustment on the initial theoretical intake F0 of each opening 31 by using the first adjustment coefficient of the intake of each opening 31 to obtain the theoretical intake F1(i) ═ F0(i) × k (i) after the first adjustment of each opening 31.

And S6, if the theoretical rotating speed N1 of the fan is greater than the maximum operating rotating speed N _ MAX allowed by the fan of the range hood, entering S8, and otherwise, entering S7.
And S7, if the theoretical rotating speed N1 of the fan is less than the minimum running rotating speed N _ MIN allowed by the fan of the range hood, entering S9, and otherwise, entering S10.
And S8, adjusting the fan rotating speed N to the maximum operation rotating speed allowed by the range hood fan, namely N is N _ MAX. Meanwhile, the theoretical intake F1(i) after the first adjustment needs to be adjusted for the second time, so as to obtain the second theoretical intake F2(i) of each opening 31, and the adjusted theoretical intake F2(i) is matched with the fan speed N, so that the final theoretical intake F (i) ═ F2(i) of each opening 31 enters S11.
The specific method of the second adjustment is as follows:
s801, a second adjustment calculation of the theoretical intake air amount F2 is performed for each opening 31 in the order from small to large of the theoretical intake air amount F1(i) after the first adjustment of each opening 31, where F2(i) ═ F1(i) × p.
And S802, after adjusting and calculating the second theoretical intake of one opening 31, matching the current theoretical intake of all the openings 31 with the fan rotating speed N, and if the current theoretical intake of all the openings 31 is matched with the fan rotating speed N, not adjusting and calculating the second theoretical intake of the residual openings 31, wherein the second theoretical intake of the residual openings 31 is F2(i) ═ F1 (i). Otherwise, the process proceeds to S801 until the second theoretical intake air amount adjustment calculation for all the openings 31 is completed.
S803: if the theoretical intake air volume of all the openings 31 is adjusted for the second time, F1(i) of each opening 31 is updated to be F2(i), and the process returns to S801 until the theoretical intake air volume of all the openings 31 currently matches the fan speed N.
And S9, adjusting the fan rotating speed N to be the minimum operation rotating speed allowed by the range hood fan, namely N-MIN. If the theoretical intake air amount F1(i) after the first adjustment is not required to be adjusted for the second time, the final theoretical intake air amount F (i) of each opening 31 is F1(i), and the process proceeds to S11.
S10, the fan speed N is the theoretical fan speed N1, that is, N is N1. If the theoretical intake air amount F1(i) after the first adjustment is not required to be adjusted for the second time, the final theoretical intake air amount F (i) of each opening 31 is F1(i), and the process proceeds to S11.
S11, the smoke ventilator control system controls the adjusting and driving unit to drive the air deflector 4 on each opening 31 to act according to the final theoretical intake air F (i) of each opening 31, and further realizes the adjustment of the opening 31 to meet the final theoretical intake air.
S12: and the smoke ventilator control system adjusts the rotating speed of the fan according to the rotating speed N of the fan. Returning to S3.
