Referring to fig. 2, the oil cup 10 of the range hood is generally designed to be a strip shape having a width equivalent to that of the range hood, and the oil cup 10 is installed at the bottom of the range hood, so that oil stains condensed at different parts of the range hood can flow into the oil cup 10 for collection.
The starting operation of the range hood referred to in this embodiment may be the moment when the range hood is just started to operate, or may be the state that the range hood has been started to be in the operation of oil smoke absorption, that is, the operation of obtaining the operation state of the range hood in this embodiment is performed in real time, and as long as the range hood is powered on, the controller can obtain the operation state of the range hood in real time to analyze.
It can be understood that the operation state obtaining mode of the range hood is not unique, and in one embodiment, an operation state detector may be arranged in the range hood to perform operation of detecting the operation state of the range hood in real time, and the operation state detector may send the operation state of the range hood to the controller in real time to perform analysis processing. The type of the running state detector is not unique, and the electric signals flowing through the range hood are inconsistent when the range hood is in different running states, so that the running state detector can detect the electric signals flowing through the range hood to realize the detection operation of the running state of the range hood.
And step S200, controlling an electrostatic oil removal device arranged in an oil cup of the range hood to start to operate according to the operation state so that the oil fume generated during the operation of the range hood is adsorbed on the electrostatic oil removal device.
Specifically, the operation state of the range hood reflects the amount of oil smoke in the kitchen to a certain extent, and when the amount of oil smoke in the kitchen is small, the user generally controls the range hood to operate at a lower gear, and when the amount of oil smoke in the kitchen is large, the user generally controls the range hood to operate at a higher gear. Therefore, in this embodiment, the analysis can be performed according to the operating state of the range hood, so as to determine whether the electrostatic oil removal device needs to be turned on to adsorb the oil smoke, thereby avoiding the consumption of electric energy.
