Variable frequency range hood, control method and device thereof, and storage medium

Abstract

The application discloses a variable frequency range hood control method and device, a range hood and a storage medium. The method comprises the following steps: acquiring a first back pressure received by a range hood during operation, and acquiring an air volume of a variable frequency fan of the range hood when the first back pressure is received; determining whether the first back pressure is in a medium back pressure interval, wherein a back pressure range that the range hood may receive during operation is preset to be multiple back pressure intervals, including a high back pressure interval, the medium back pressure interval and a low back pressure interval; if yes, determining a target operating parameter of the variable frequency fan according to the first back pressure and the air volume; and controlling the variable frequency fan to operate according to the target operating parameter. The application improves the oil fume suction effect of the range hood by more accurately controlling the variable frequency fan of the range hood.
