Multi-cyclone dust collector for vacuum cleaner

Abstract

The present invention relates to a multi-cyclone dust collector for a vacuum cleaner. The multi-cyclone dust collector includes a first cyclone forcing contaminants-laden air that is drawn-in at a lower portion of the first cyclone to form an upwardly whirling air current so as to centrifugally separate contaminants therefrom air, a first contaminants chamber wrapping around a first part of the first cyclone and collecting contaminants discharged from the first cyclone, and a second cyclone unit wrapping around a second part of the first cyclone and having a plurality of second cyclones, each of the plurality of second cyclones drawing-in semi-clean air discharged from the first cyclone at an upper portion of each of the plurality of second cyclones so as to centrifugally separate fine contaminants from the semi-clean air.

Description

[0001] This application claims the benefit of U.S. Provisional Application No. 60 / 728,108, filed October 19, 2005, in the United States Patent and Trademark Office, and Korean Application No. 2005-0113033, filed November 24, 2005, in the Korean Intellectual Property Office The benefit of patent applications, the contents of both applications are hereby incorporated by reference. technical field [0002] The present invention relates to a vacuum cleaner, and more particularly, to a multi-cyclone dust collector for a vacuum cleaner, which separates and collects dirt from air through two steps and more. Background technique [0003] Generally, a cyclone dust collector is a device that causes a fluid such as air to rotate and then collects dirt separated from the rotating fluid by centrifugal force. Cyclone dust collectors are now widely used as dirt collecting devices for vacuum cleaners. [0004] A conventional cyclone dust collector for a vacuum cleaner includes a cyclone bo...

AI Technical Summary

Problems solved by technology

[0007] The traditional multi-cyclone dust collector has a complex structure due to the use of multiple cyclones

Therefore, the conventional multi-cyclone dust collector is difficult to manufacture, and it is difficult to empty the dirt collected in each of the first dirt container and the second dirt container

[0008] In addition, in the traditional multi-cyclone dust collector, most of the dirt separated from the inhaled air is collected in the first dirt container, but due to the structure of the traditional multi-cyclone dust collector, the user is in the traditional multi-cyclone dust The dirt collected in the first dirt container is not visible from the outside of the collector

Therefore, it is not convenient for the user to manipulate the multi-cyclone dust collector

[0009] In addition, the conventional multi-cyclone dust collector has a high height because the first dirt container is located below the first cyclone
