After the controller obtains the starting instruction, the user needs to start the range hood, and at the moment, the controller sends a starting signal to the fan system 21 of the range hood, wherein the starting signal is used for controlling the fan system 21 to absorb cooking oil smoke. The structure of fan system 21 is not exclusive, and in this embodiment, fan system 21 includes main motor 211, wind wheel 212, and a volute, main motor 211 and wind wheel 212 are disposed in the volute, wind wheel 212 is disposed on main motor 211, and main motor 211 is connected to the controller.

Step S400: and sending a purification command to the purification device.
Wherein, purification instruction is used for controlling purifier 12 to purify the oil smoke that fan system 21 was absorbed, and purifier 12 sets up in the lampblack absorber. After the fan system 21 is started, the fan system 21 starts to absorb cooking oil smoke, and at this time, a purification instruction is sent to the purification device 12 to control the purification device 12 to start working, so as to purify the oil smoke absorbed 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 controller is connected to the generator 122 and the collector 123, and the controller sends the purifying instruction to the purifying device 12, so that the controller energizes the generator and the collector 123 of the purifying device 12.
Specifically, when the purifying device 12 operates, the soot reaches the generating electrode 122 first and then reaches the collecting electrode 123. Wherein, the generating electrode 122 is connected with high voltage electricity (generally adopting 7-9 KV high voltage electricity), taking the purifying device 12 arranged 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 area. Under the action of corona of the high-voltage electric field, dust-containing airflow enters a corona discharge area, and electric charges are generated on dust particles.
Generally, low voltage is applied to the collector 123, so that opposite electricity is generated on the collector 123, and the charged particles are adsorbed by adopting the principle of 'opposite attraction', and can be generally connected with 3-4 KV. The collector 123 has an electrical property different from that of the charged particles, and therefore the collector and the charged particles are attracted to each other by the coulomb force of the electric field, so that the charged particles are adsorbed. The coulomb force is the electric field force acting between two charges, the magnitude of the interaction force between two static point charges Q1 and Q2 in vacuum is in direct proportion to the product of Q1 and Q2 and in inverse proportion to the square of the distance r between the two static point charges, the direction of the interaction force is along the connecting line of the two static point charges, the same charges repel each other, and the different charges attract each other. It is understood that in other embodiments, the purification apparatus 12 may also include other structures, as long as those skilled in the art recognize that they can be implemented.
Step S600: and after a shutdown instruction is obtained, sending a self-cleaning instruction to the purification device.
The device for acquiring the shutdown instruction is an instruction acquisition device, and the instruction acquisition device is connected with the controller and sends the acquired shutdown instruction to the controller. The instruction acquisition device is usually arranged on the shell of the range hood, the type of the instruction acquisition device is not unique, for example, the instruction acquisition device can be a key, the operation is simple, and the instruction acquisition device can also be a voice recognition device or a gesture recognition device, so that the use convenience is high, and the instruction acquisition device is not particularly limited. After the controller obtains the shutdown instruction, the range hood can be closed in consideration of the cooking completion. At this time, the controller sends a self-cleaning command to the purifying device 12, and the self-cleaning command is used for controlling the purifying device 12 to remove grease, so that the purifying device 12 can remove grease attached during the work process, and self-cleaning of the purifying device 12 is realized. The mode that purifier 12 removed grease is not the only, generally, contains rotatable device in purifier 12, and after purifier 12 received the automatically cleaning instruction, the device began to rotate, and the grease particulate matter that adheres to on rotatory device is thrown away under the centrifugal force effect, realizes purifier 12's automatically cleaning, has further ensured purifier 12's working property, has improved purifier 12's purification ability to the use reliability of lampblack absorber has been improved. It is understood that in other embodiments, the cleaning device 12 may remove the attached grease by vibration or the like, as long as the skilled person realizes.
In an extensible manner, after a shutdown instruction is acquired, whether delayed shutdown is needed or not is judged according to the shutdown instruction, if yes, the following steps are executed, namely step S600 and the like are executed, if the delayed shutdown is not needed, the range hood is directly shut down, at the moment, subsequent self-cleaning action is not executed, and therefore the range hood can be directly shut down when cleaning is not needed, and therefore the user requirements are better met.

When the purifying device 12 works, the generator 122 is powered on by high voltage electricity, the collector 123 is powered on by low voltage electricity, when oil smoke enters the generator 122 passing through the purifying device 12 from the air inlet, under the action of corona of a high-voltage electric field, oil smoke air is ionized to generate electric charges, and the electric charges collide grease particles and dust to enable the oil smoke particles and the dust to be charged. When the particulate matter accumulating electric charges passes through the collector 123, the particulate matter is adsorbed on the collector 123 of the purifying device 12 under the action of coulomb force, so that the particulate matter in the oil smoke is separated, and the oil smoke purification is realized. The purified oil smoke passes through the air duct system and then is discharged to a public flue or outdoors through the check valve and the smoke tube. In an expandable manner, when the range hood is in a working state, the collector 123 on the purifying device 12 is connected with a low-voltage power supply and is in a low-speed running state along with the motor shaft of the auxiliary motor 121, so that the adsorption capacity of charged particles is improved. It is understood that the low speed operation here means that the rotation speed of the motor is low, and generally can be lower than the rotation speed of the lowest gear of the range hood.

Further, the first rotation command may be used to control the auxiliary motor 121 to rotate the collector 123 at a super high speed, so as to improve the purification capability of the purification apparatus 12. It is understood that the ultra high speed is defined relative to the gear rotating speed when the range hood normally operates, and the ultra high speed can be defined as the rotating speed higher than the stir-frying gear.
In one embodiment, before sending the rotation command to the auxiliary motor 121 in step S620, the method further includes: the collector 123 is powered off.

Furthermore, the power supply of the collector 123 is cut off before the rotation command is sent to the collector 123, so that the collector 123 can be prevented from being electrified and rotated, and the working safety of the collector 123 is improved.
