s3, the indoor smoke machine increases the air quantity, and reports the smoke leakage information to the outdoor control system;
and S4, after receiving the smoke leakage information, the outdoor control system controls the outdoor main fan to start, and the outdoor main fan runs at a certain gear, so that the reported indoor smoke machine has no smoke leakage, and meanwhile, the indoor smoke machine which has not been reported further reduces the air volume until the minimum air volume which enables the indoor smoke machine which has not been reported to keep no smoke leakage is reached.
In the embodiment, after the indoor range hood is started, whether the indoor range hood has smoke leakage or not is detected in real time, the purpose is to judge whether the started indoor range hood can suck all the oil smoke generated by cooking of a user into a common flue, if so, no smoke leakage exists, the power of the indoor range hood is enough, and the air quantity of the indoor range hood is reduced until the minimum air quantity which enables the indoor range hood to keep no smoke leakage is reached, so that the indoor range hood is ensured to have no smoke leakage, the noise is reduced, and the energy consumption is reduced; if the indoor range hood is not powered enough, the power of the indoor range hood is insufficient, so that the air volume of the indoor range hood needs to be increased, but if the problem of smoke leakage of the indoor range hood is solved by only increasing the air volume of the indoor range hood, the noise is high, even if the air volume of the indoor range hood reaches the maximum, the problem of smoke leakage still exists, and therefore the smoke leakage information needs to be reported to an outdoor control system.
After receiving the smoke leakage information, the outdoor control system controls the outdoor main fan to start and enables the outdoor main fan to operate at a moving gear, so that the reported indoor range hood has no smoke leakage; after the outdoor main fan is started, the pressure in the public flue is changed, and the air volume of each floor is correspondingly changed, so that the indoor smoke machine which is not reported needs to further reduce the air volume until the minimum air volume which enables the indoor smoke machine which is not reported to keep no smoke leakage is reached, the air volume of a user with low air volume is reduced, the user with high air volume is compensated, the same air volume is not distributed to each household uniformly, the reasonable distribution of power is realized, the practicability of the whole central flue air volume control system is improved, the smoking effect of the indoor smoke machine of each floor is ensured, and meanwhile, the noise and the energy consumption are reduced as much as possible.

In a specific embodiment, if the number N of reported indoor smoke machines reaches a number threshold N, the gears of the outdoor main fans are adjusted, and the air volume is increased on the basis of the gears, wherein the number threshold N is the number of reported indoor smoke machines required by the adjustment of the gears of the outdoor main fans.
For example, the number threshold N may be 5, 13, 22, and when the number N of reported indoor smoke ventilators is less than 5, the corresponding operating gear of the outdoor main blower is 1 gear; when the reported number n of the indoor smoke machines is less than 13, the corresponding operation gear of the outdoor main fan is 2; when the reported number n of the indoor smoke machines is less than 22, the corresponding operation gear of the outdoor main fan is 3 gears, namely, the more the reported number n of the indoor smoke machines is, the higher the gear of the outdoor main fan is.
Assuming that the number of indoor smoke machines reported currently is 10, and 10 is less than 13, the current outdoor main fan runs at the 2 nd gear, so that the 10 reported indoor smoke machines are all in a smoke leakage-free state; suddenly, a plurality of indoor smoke machines are started, the number of reported indoor smoke machines is increased to 25, if the outdoor main fan still runs at the 2 nd gear, all reported indoor smoke machines cannot be in a smoke leakage free state, so that the outdoor main fan adjusts the gear to the 3 rd gear to improve the air quantity, and when the outdoor main fan runs at the 3 rd gear, all reported indoor smoke machines can be in the smoke leakage free state.
In a specific embodiment, if the reported number of indoor smoke machines is large, the outdoor main fan operates at a high level; otherwise, the engine is operated in a low gear.
In a specific embodiment, if only one indoor smoke machine reports, the outdoor main fan operates at the lowest gear.
Further, indoor cigarette machine starts the back, and the indoor cigarette machine of real-time detection has or not runs the cigarette, specifically includes:
the indoor cigarette machine starts, and the electronic check valve of indoor cigarette machine is opened to the maximum angle in step, and real-time detection indoor cigarette machine has or not runs the cigarette.
