Fig. 4 shows a schematic diagram of the designed novel rangehood; it consists mainly of six functional groups. The impeller is the key part of the dynamic system that creates an exhaustfor cooking emissions. The electric motor is responsible forimpeller rotation while the grease collector is used to collectgrease particles separated by the novel range hood. The outercylinder provides structural function and traps the particlesand oil droplets through centrifugation. In the medial of theouter cylinder and above the impeller, there is an inner cylinderfixed in the outer cylinder by means of connecting parts. It providesspace for electric motor installation and reduces the risk ofcorrosion caused by cooking emissions. The last module consistingof guide vanes to adjust the outlet flow direction of fumes isdefined as GVE.
