Questions about Vacuum Cleaner Technology: 1. How does the impeller in the intake portion of the vacuum cleaner contribute to air flow efficiency? 2. What are the specific advantages of using diffuser vanes with an airfoil shape in a vacuum cleaner?
Original Abstract Submitted
A vacuum cleaner including an intake portion within a main body, wherein the intake portion includes an impeller to draw in air while rotating about a shaft, and a plurality of diffuser vanes to guide air discharged from the impeller, wherein each of the diffuser vanes includes a single vane body having an airfoil shape in cross section, and a passage to cross through at least a portion of the vane body. The vacuum cleaner is capable of effectively changing the direction of a flow flowing into a diffuser, and reducing losses caused by flow separation.
