Vacuum cleaner

Abstract

A vacuum cleaner has an air passage for inhaling air, and one or more parts of the passage are nano-coated with an antibacterial and bactericidal material. In one embodiment, a vacuum cleaner includes: a suction brush having an air inlet; a dust collection device in fluid communication with the suction brush; and a body having a dust collection device mounting location and a motor assembly for generating suction. Part or parts of the air passage surface of the dust collection device in contact with the air are nano-coated with an antibacterial and sterilizing material.

Description

[0001] This application claims the benefit of Korean Patent Application No. 2004-110041 filed with the Korean Intellectual Property Office on December 22, 2004, the disclosure of which is incorporated herein by reference in its entirety. technical field [0002] The present invention generally relates to the field of vacuum cleaners, and in some embodiments, the present invention relates to antibacterial and germicidal functions used in vacuum cleaners, among others. Background technique [0003] Generally, a vacuum cleaner rotates a motor to generate suction for sucking in dust and dirt-laden air, separates and collects the dust and dirt (hereinafter referred to as dirt) from the sucked air using a dust collection device, and removes the dirt-free clean air discharged to the outside. [0004] In a dust collecting device that collects dirt separated from the air containing dirt, microorganisms or bacteria contained in the dirt are collected together. Typically, the dirt col...

Problems solved by technology

[0007] In addition, an increase in the amount of nano-silver particles added to the original plastic material reduces the productivity of the injection molding process and reduces the strength of the resulting part

[0008] In other words, it is difficult to achieve effective antibacterial and sterilizing functions by using the traditional method of adding nano-silver particles to the original plastic material
