WIPO Patent Application WO/2024/088013
Kind Code:
A1
Abstract:
The present application relates to a range hood. The range hood comprises a current signal collector and a controller. In the range hood, an instruction acquisition module acquires an operation instruction, and transmits the operation instruction to a calculation module; the calculation module parses the operation instruction, acquires a target operation parameter, and transmits the target operation parameter to a control module; the control module controls the operation of a smoke extraction fan on the basis of the target operation parameter; the current signal collector collects a current signal in the operation process of the smoke extraction fan, and transmits the current signal to a feedback module; the feedback module calculates an actual operation parameter of the smoke extraction fan on the basis of the current signal, and transmits the actual operation parameter to the calculation module; the calculation module calculates a corrected value on the basis of the actual operation parameter and the target operation parameter, and transmits the corrected value to the control module; and the control module corrects the operation parameter of the smoke extraction fan on the basis of the corrected value.
