First Claim
Patent Images
1. A dust collection unit of a vacuum cleaner, comprising:
- a dust collection container separating foreign particles contained in air including introduced dust using a rotational stream of the air to collect the separated foreign particles;
a lower cover for selectively opening a lower portion of the dust collection container;
a hinge portion connecting the dust collection container and the lower cover such that the lower cover is opened or closed;
a coupling portion for selectively latching the lower cover to the dust collection container; and
an exhaust part concaved inward from an outer circumferential surface of the dust collection container and having the coupling portion in the concaved inside.

Abstract
Provided is a dust collection unit of a vacuum cleaner, including a dust collection container and a coupling portion formed at a concaved inside of the dust collection container, for allowing a lower cover to be selectively coupled to the dust collection container. The dust collection unit is firmly supported against an external impact, thereby enhancing the reliability of the vacuum cleaner and preventing the vacuum cleaner from being damaged.

17. A vacuum cleaner comprising:
-
a suction nozzle unit through which outer air is sucked;
a body receiving at least a motor and a suction fan;
a manipulation handle formed at an upper portion of the body, for manipulating the vacuum cleaner;
a dust collection unit selectively received in the body and through which air that sucked from the body and filtered is discharged;
