After the controller obtains the starting instruction, the range hood is started by considering the requirement of a user, and the controller controls the fan system 21 to suck and exhaust oil smoke at the moment. The structure of the fan system 21 is not exclusive, in the present embodiment, the fan system 21 includes a main motor 211, a wind wheel 212, and a volute 213, the main motor 211 and the wind wheel 212 are disposed in the volute 213, the wind wheel 212 is disposed on the main motor 211, and the main motor 211 is connected to the controller. The controller controls the main motor 211 to start, the main motor 211 drives the wind wheel 212 to rotate after being started, negative pressure is generated to absorb cooking oil smoke, and then the absorbed oil smoke is discharged through the wind wheel 212. The range hood further includes a smoke collecting hood assembly, which is generally disposed in an area closest to the range of the range hood, for collecting smoke, and cooperates with the fan system 21 to absorb the smoke generated during combustion and cooking of the range hood. The specific shape, size and the like of the smoke collecting hood assembly can be designed according to actual requirements, so long as the realization can be realized by the technical personnel in the field.

After the fan system 21 is started, the fan system 21 starts to suck and discharge the oil smoke, and at this time, the controller may control the purifying device 12 to start to operate to purify the oil smoke sucked by the fan system 21. It is understood that the purifying device 12 can purify the oil smoke before entering the fan system 21, or can purify the oil smoke after passing through the fan system 21. The process of purifying the oil smoke by the purifying device 12 is different according to the structure and type of the purifying device 12. In this embodiment, the purifying device 12 is taken as the electrostatic purifying device 12, the electrostatic purifying device 12 includes the generator 122 and the collector 123 as an example, the generator 122 is disposed at an upper air inlet of the range hood, the collector 123 is disposed at a lower air inlet of the range hood, the generator 122 and the collector 123 are disposed along an air direction of the range hood, the oil smoke firstly passes through the generator and then reaches the collector 123, and the controller is connected to the generator 122 and the collector 123 to energize the generator 122 and the collector 123.

Specifically, when the purifying device 12 operates, the soot reaches the generating electrode 122 first and then reaches the collecting electrode 123. The structure of the generating electrode 122 can be seen in fig. 5, and the structure of the collecting electrode 123 can be seen in fig. 6. Wherein, the generating electrode 122 is connected with high voltage electricity (generally adopting 7-9KV high voltage electricity), taking the purifying device 12 disposed at the air inlet of the range hood as an example, when the oil smoke enters from the air inlet through the generating electrode 122 of the purifying device 12, ions and electrons in the gas are accelerated under the action of the strong electric field near the discharging electrode, so that the ions or electrons have enough kinetic energy to collide with the gas molecules and ionize them, and further more ions and electrons are generated to form a corona discharge region.
