Specifically, the user needs the smoke machine to absorb the oil smoke during cooking, and at the moment, the smoke machine is started and started by initial current.

And S120, based on the initial current, adjusting the current and the noise value of the smoke machine according to a preset current-noise fitting curve until the noise value of the smoke machine reaches a target noise value.

The preset current-noise fitting curve can be understood as a preset relation curve of noise along with current change under ideal conditions; in an alternative embodiment of the present invention, noise corresponding to the rotational speeds of several nodes in the rotational speed adjustable range and current corresponding to the noise may be measured in advance. FIG. 2 is a graph of current versus rotational speed according to an embodiment of the present invention, and referring to FIG. 2, the current I and the rotational speed N are three times; and the rotation speed and noise are positively correlated, so that a cubic function is used for approximating the relation between fitting current and noise, in the fitting process, in order to ensure the fitting accuracy, an intermediate judgment point A2 is added between end points A1 and A3, and then the relation between noise and current is based on: S=KI ³, fitting the curves of two adjacent points, wherein S is noise, K is constant, and finally obtaining a fitting curve of noise and current, and the fitting curve obtained by the method is relatively low in accuracy. In another embodiment of the invention, the segments are segmented between two end points of the noise adjustable range by adding points, each segment is supplemented, and the segments are fitted in a curve form to obtain a fitting formula Wherein a, b, c, d are constants, y is a noise value, and x is a current value; besides the current value, the air quantity parameter can be introduced to perform fitting more in line with reality and accuracy, namely, the mapping relation between the double parameters based on the current and the air quantity and noise output is obtained, and therefore a three-dimensional fitting curved surface is obtained, and the method is not limited.

Specifically, when the noise of the smoke machine is regulated through the current, the noise value is regulated from 60 db to 59 db and from 59 db to 58 db by way of example when the noise value is different, and the required current value is different, so that the current value required for regulating the noise each time can be obtained according to a preset current-noise fitting curve, and the current and the noise value of the smoke machine are regulated according to the preset current-noise fitting curve, so that the noise value changes smoothly until the noise value of the smoke machine reaches the target noise value.

Specifically, in an alternative embodiment of the present invention, in order to stably change the noise, the noise value of each change needs to be the same, that is, the current required by the noise value of each constant step change can be known according to a preset current-noise fitting curve, and when the current is required to be adjusted from 60 db to 55 db, for example, 1 db is required to be changed each time in order to ensure that the change is stable, according to the preset current-noise fitting curve, the current required to be adjusted from 60 db to 59 db is 1a, and from 59 db to 58 db is required to be 0.8A, and according to the current obtained each time, the current is gradually adjusted until the noise value of the smoke machine reaches the target noise value.

In one embodiment, in step S120, based on the initial current, the current and the noise value of the smoke machine are adjusted according to a preset current-noise fitting curve, until the noise value of the smoke machine reaches the target noise value, and the current and the noise value of the smoke machine are increased:

Detecting the adjusted noise value;

Specifically, after the noise value is adjusted according to the current value obtained by the preset current-noise fitting curve, it is also required to determine whether the adjusted actual noise value is the same as the noise value corresponding to the corresponding current in the curve, i.e. whether the preset curve is accurate, so that the adjusted noise value needs to be detected.

the preset limit value may be understood as a limit value preset by a user, beyond which the error is considered to be beyond an acceptable range, and the current-noise fitting curve needs to be corrected.

If not, correcting the current-noise fitting curve in real time;

And step 120, based on the initial current, adjusting the current and the noise value of the smoke machine according to a preset current-noise fitting curve until the noise value of the smoke machine reaches a target noise value, and refining as follows:

Specifically, after the current-noise fitting curve is corrected, the noise is adjusted according to the current obtained by the new current-noise fitting curve, whether the difference value between the actual noise and the corresponding noise value on the corrected current-noise fitting curve is smaller than a preset limit value is judged, and when the difference value is smaller than the difference value, the corrected curve is used for adjusting the noise to the target noise value.
