Dust and dirt collecting unit for vacuum cleaner
First Claim
1. A dust and dirt collecting unit provided with a main body of the vacuum cleaner and configured to filter sucked air containing foreign substances, comprising:
- a substantially cylindrical casing which has an open top portion and an inlet formed in a direction tangential to the casing which is configured to introduce air containing foreign substances into the casing;
a cover provided at the open top portion of the casing, said cover including an outlet for discharging air from which foreign substances have been filtered out;
a filter assembly provided at a bottom portion of the cover corresponding to the outlet, wherein the filter assembly includes a substantially cylindrical filter surrounding a substantially cylindrical lattice frame whose interior is in communication with the outlet, a radially extending upper flange portion which comes into close contact with the lower surface of the cover, and a body which extends downward from the upper flange portion to form the substantially cylindrical lattice frame which allows air to pass therethrough;
a substantially cylindrical protective body configured to surround an outer periphery of the filter assembly, wherein the protective body includes a plurality of vent holes formed at a lower portion thereof which are configured to maintain airflow communication between an interior and an exterior of the protective body; and
a separating plate coupled to a bottom of the filter assembly and extending radially outward therefrom such that at least a portion of an outer peripheral surface of the separating plate is spaced apart from an inner circumferential surface of the dust casing by a predetermined gap.

Abstract
The present invention relates to a dust and dirt collecting unit for a vacuum cleaner capable of simultaneously performing a primary cyclonic dust collection and a secondary filter dust collection. According to the present invention, there is provided a dust and dirt collecting unit for a vacuum cleaner, which is mounted to one side of a main body of the vacuum cleaner to filter sucked air containing foreign substances. The dust and dirt collecting unit of the present invention comprises a dust casing which has an inlet formed in a direction tangential thereto for introducing the air containing the foreign substances thereinto and of which a top portion is open; a cover which is used to open and close the top portion of the dust casing and is provided at the center thereof with an outlet for discharging air from which the foreign substances have been filtered out; a filter assembly which is installed at a bottom surface of the cover corresponding to the outlet and includes a cylindrical filter of which the interior communicates with the outlet; a protective cylindrical body which is formed to wrap around an outer periphery of the filter assembly and installed below the cover so that the interior thereof can communicate with the exterior thereof through a plurality of vent holes formed at a lower portion thereof; and a separating plate which is coupled with the bottom of the filter assembly and extends radially to be spaced apart from an inner circumferential surface of the dust casing by a predetermined gap.
