Problems solved by technology

[0003] At present, during the use of the range hood in the prior art, the surface of the gas sensor is easily polluted by oil, resulting in a greatly reduced detection sensitivity, a high concentration of oil fume, and a situation where the fan cannot operate automatically; frequent maintenance, some Even electronic components need to be replaced, which brings great inconvenience to users
In addition, most range hoods on the market work at the gear selected by the user. When the cooking mode changes, if the gear is not switched in time, it will easily cause a large amount of fumes to escape, which will affect the smoke removal effect of the range hood.

Description

technical field [0001] The invention relates to the technical field of range hood control, in particular to a range hood control device and method based on an AC coupling charge induction method. Background technique [0002] Oily fumes from daily cooking contain viscous gas particles and harmful gas components. Therefore, the range hood has become one of the more and more indispensable kitchen appliances in the family. The working principle of the range hood is to form a certain negative pressure area in the space above the stove through the fan, and then absorb, filter, and purify the fumes in the kitchen and discharge them outside. [0003] At present, during the use of the range hood in the prior art, the surface of the gas sensor is easily polluted by oil, resulting in a greatly reduced detection sensitivity, a high concentration of oil fume, and a situation where the fan cannot operate automatically; frequent maintenance, some Even electronic components need to be re...
