Benefits of technology

[0010] The present invention has been developed in order to overcome the above drawbacks and other problems associated with the conventional arrangement. An aspect of the present invention is to provide a fan assembly for a vacuum cleaner to reduce noise, especially BPF noises, generated by an impeller. The above aspect and/or other feature of the present invention can substantially be achieved by providing a fan assembly for a vacuum clea

Problems solved by technology

However, the fan assembly 7 generates a loud noise because the impeller rotates at high speed inside the diffuser 8.
BPF noises do not greatly

Abstract

The present invention relates to a fan assembly for a vacuum cleaner for reducing BPF noises. The fan assembly includes a motor, an impeller having a plurality of impeller blades, the impeller being rotated by the motor to suck air, and a diffuser disposed to wrap around an outer circumference of the impeller, the diffuser having a plurality of diffuser blades arranged in a predetermined interval. A ratio of an exit area of the diffuser to an entrance area of the diffuser is determined to reduce noise generated when the impeller rotates.

Description

REFERENCE TO RELATED APPLICATION [0001] This application claims the benefit under 35 U.S.C. § 119(a) from Korean Patent Application No. 2005-114158 filed on Nov. 28, 2005 in the Korean Intellectual Property Office, the disclosure of which is incorporated herein by reference in its entirety. BACKGROUND OF THE INVENTION [0002] 1. Field of the Invention [0003] The present invention relates to a vacuum cleaner. More particularly, the present invention relates to a fan assembly for a vacuum cleaner. [0004] 1. Description of the Related Art [0005] Generally, a vacuum cleaner is an apparatus that sucks contaminants with air by suction force, and then, separates and collects contaminants from the sucked air using a contaminants collecting apparatus. An example of the vacuum cleaner is shown in FIG. 1. [0006] Referring to FIG. 1, the vacuum cleaner 1 includes a suction brush 2, an extension pipe assembly 3, and a main body 4. [0007] The suction brush 2 is provided with a suction port (not sh...
