Abstract

The application discloses a range hood and a shutdown control method and device thereof, and is applied to the field of kitchen appliances. Smoke concentration data sets of an environment where the range hood is located are acquired. When a shutdown command for the range hood is acquired, current smoke diffusion degree information is determined according to the smoke concentration data sets. A delay shutdown program is set according to the current smoke diffusion degree information, and the range hood is controlled to be shut down based on the set delay shutdown program. The technical problem that the delay shutdown of the range hood has a poor smoke absorption effect is at least solved to a certain extent.
