Benefits of technology

"The present invention provides a vacuum cleaner with an improved dust agitator that prevents abrasions against surfaces being vacuumed and increases cleaning efficiency. The dust agitator includes a bristle member with a plurality of bristles of varying thickness embedded in a receiving groove of the dust agitator body. The bristle member includes a first bristle member embedded in the receiving groove and a second bristle member embedded with the first bristle member in the receiving groove but thinner than the first bristle member. The receiving groove is helically configured along with the outer dust agitator body to reduce abrasions against surfaces to be vacuumed. The vacuum cleaner with the dust agitator includes a cleaner body, a suction nozzle, a dust agitator body, a receiving groove for the bristle member, and a bristle member embedded in the receiving groove for the bristle member."

Problems solved by technology

If the surface being vacuumed includes a fabric such as a carpet, however, abrasion of the carpet surface can occur by friction with the bristle member.

Embodiment Construction

[0017] Certain embodiments of the present invention will be described in greater detail with reference to the accompanying drawings.

[0018] A conventional up-right type vacuum cleaner as shown in FIG. 1 includes a cleaner body 10 and a suction nozzle 20 provided with a suction opening. The cleaner body 10 houses therein a dust collector which has a dust bag, and is covered with a dust collector cover 11 and a motor driver 12 installed with a motor.

[0019] The suction nozzle 20 of the up-right type vacuum cleaner 10 suctions dust and alien substances from surfaces vacuumed with air and collects dust in the dust bag of the dust collector when a motor operates to generate a suction power.

[0020] To remove alien substances deeply stuck in surfaces being vacuumed such as a carpet or a floor, the suction nozzle 20 includes a dust agitator 100. The dust agitator 100 is rotatably installed in a housing 21 of the suction nozzle 20, and the dust agitator 100 is connected to a motor through a ...

Abstract

A dust agitator of a vacuum cleaner is disclosed. The dust agitator of the vacuum cleaner includes a thick and a thin bristle member embedded in a single bristle member suction opening so that abrasion of a surface being vacuumed can be reduced and cleaning efficiency can be increased. The dust agitator includes a dust agitator body, a receiving hole for a bristle member being configured along the dust agitator body, and a bristle member comprising a plurality of first and second bristle members of varying thickness being embedded in the receiving hole.

Description

REFERENCE TO RELATED APPLICATION [0001] This application claims priority to co-pending Korean Patent Application No. 2003-91265 filed on Dec. 15, 2003, in the Korean Intellectual Property Office, the entire contents of which are incorporated herein by reference. FIELD OF THE INVENTION [0002] The present invention relates to a vacuum cleaner, and more particularly, to a dust agitator for a vacuum cleaner with an improved bristle member to more effectively scatter dust from surfaces being vacuumed. BACKGROUND OF THE INVENTION [0003] A dust agitator is provided at a suction bristle of an upright type cleaner or a canister type cleaner to scatter dust off the surface being vacuumed, and to increase cleaning efficiency. A plurality of bristle members are helically embedded in the dust agitator, and cleaning efficiency depends on the strength of the bristle members. [0004] Cleaning efficiency is increased if the bristle members are lengthened and thickened so that the bristle members have...
