The intelligent degree of this scheme is high, can effectively reduce user's operation, improves user's use and experiences. Moreover, the rotating speed is adjusted according to the smoke concentration, so that compared with manual adjustment of a user, the situation that the air volume is small when the amount of oil smoke is large does not occur, and the situation that the air volume is large when the amount of oil smoke is small does not occur; the oil fume suction effect is better, and the energy is more saved.

By predicting the running oscillogram, the cooking habits of the user can be effectively reflected.
Further, the server is also used for sending the predicted operation oscillogram to the control module; the control module is used for judging whether the smoke concentration value in the second preset time is continuously smaller than or equal to the preset closing threshold value or not, and is also used for matching a corresponding predicted operation oscillogram according to the current date, calculating the number of predicted wave peaks in the predicted operation oscillogram and the wave peak interval duration between every two wave peaks, and generating predicted duration according to the wave peak interval durations of all the wave peaks; the control module is also used for acquiring current operation data of the fan started at this time, and generating a current operation oscillogram of the fan by taking the rotating speed of the fan as a vertical coordinate and the operation time as a horizontal coordinate; the control module is further used for calculating the number of current wave crests in the current running oscillogram of the fan, judging whether the number of the current wave crests is smaller than the number of the predicted wave crests, and if so, taking the predicted time length as new second preset time.
Since the second preset time is initially a specific value, it cannot completely represent all people's cooking habits. For example, some people have a fast pace, the interval between cooking two dishes is short, other people have a slow pace, and the interval between cooking two dishes is long. According to the optimal scheme, whether the user fries the whole part of dishes at present can be predicted by judging whether the number of the current wave crests is smaller than the number of the predicted wave crests. And generating a predicted time length according to the peak interval time lengths of all the peaks, effectively predicting the interval time between the two dishes fried by the user, and taking the predicted time length as a new second preset time to enable the new second preset time to be more in line with the habit of the user.
Further, the new second preset time does not exceed 120 s.
And a new upper limit of second preset time is set, so that the problem of overlarge energy consumption of the fan due to long-time idling can be avoided.
