Abstract

A cyclone dust collecting apparatus and a cleaner having the same include a grille unit including an introduction pipe communicating with the suction port and adapted to guide the air into the main cyclone chamber, and a grille body detachably provided to the introduction pipe and allowing the air to be discharged from the main cyclone chamber after dust particles in the air having a size greater than or equal to a certain size is filtered out. With this configuration, the spatial utilization of the cyclone structure may be facilitated, and visualization of the dust collection chamber may allow a user to gain satisfaction from cleaning operation.

First claim

What is claimed is:

1. A dust collecting apparatus comprising: a dust collecting case including a dust separation part to separate dust from air suctioned thereinto; a dust collection container including a dust collection chamber to collect the dust separated from the air, an opening to open the dust collection chamber, and a fixed protrusion formed on a surface of the dust collection container adjacent to the opening, the dust collection container being arranged at one side of the dust collecting case; a discharge cover including a cover body to open and close the opening, and a catch member adapted to be restricted by the fixed protrusion at the one side of the cover body, the discharge cover being pivotably hinged to the dust collecting case; an opening and closing member formed on one side surface of the dust collection container to release the catch member from restriction by the fixed protrusion, the opening and closing member including: an opening and closing member body adapted to slide along the one side surface of the dust collection container, a catch release part provided to the opening and closing member body to space the catch member from the fixed protrusion, a restorable elastic part to press the opening and closing member body toward an original position of the opening and closing member body when the opening and closing member body slides, an elastic pressing part allowing the restorable elastic part to be elastically supported by the opening and closing member body, a cover spacing member between the dust collection container and the discharge cover to space the dust collection container and the discharge cover apart from each other, the cover spacing member including: a seating part adapted to be seated on an inner side surface of the discharge cover; and a pressing part arranged along a circumference of the seating part and adapted to push the dust collection container through elasticity thereof when the discharge cover is opened.

2. The dust collecting apparatus according to claim 1 , wherein a direction of movement of the opening and closing member is perpendicular to a direction of the discharge cover being spaced from the dust collection container.

3. The dust collecting apparatus according to claim 1 , wherein the catch release part comprises a catch release surface inclined in a direction opposite to a direction of movement of the opening and closing member body to space the catch member apart from the fixed protrusion.

4. The dust collecting apparatus according to claim 1 , wherein the catch member comprises: a catch member body extending from the discharge cover toward an outside of the dust collection container; and a catch protrusion provided to an end of the catch member body and adapted to be caught by the fixed protrusion.

5. The dust collecting apparatus according to claim 1 , wherein the cover spacing member is formed of a material having elasticity.

6. The dust collecting apparatus according to claim 1 , wherein the cover spacing member applies elastic force toward the dust collection container to space the discharge cover apart from the dust collection container.

7. The dust collecting apparatus according to claim 1 , wherein the dust collection container is formed in a cylindrical shape, and the cover spacing member is formed in an arc shape at an inner side of the discharge cover.

8. The dust collecting apparatus according to claim 1 , wherein the discharge cover comprises a cover hinge adapted be hinged to the dust collection container, wherein the cover hinge, the cover spacing member, and the catch member are disposed in the same line.

9. The dust collecting apparatus according to claim 1 , wherein the opening and closing member has a first curvature.

10. The dust collecting apparatus according to claim 9 , wherein the first curvature is substantially identical to a second curvature of the outer surface of the dust collection container.

11. A dust collecting apparatus comprising: a dust collecting case including a dust separation part to separate dust from air suctioned thereinto; a dust collection container including an opening having one open surface and disposed at one side of the dust collecting case; a discharge cover including a catch member extending from one side thereof toward the dust collection container in a first direction to be detachably connected to the dust collection container, the other side of the discharge cover being pivotably hinged to the dust collection container to open and close the opening; an opening and closing member to move in a second direction perpendicular to the first direction to allow the catch member to escape from the dust collection container, the an opening and closing member body adapted to slide along the one side surface of the dust collection container, a catch release part provided to the opening and closing member body to space the catch member from the fixed protrusion, a restorable elastic part to press the opening and closing member body toward an original position of the opening and closing member body when the opening and closing member body slides, an elastic pressing part allowing the restorable elastic part to be elastically supported by the opening and closing member body, a cover spacing member provided between the dust collection container and the discharge cover to space the discharge cover apart from the dust collection container in a third direction opposite to the first direction, the cover spacing member including: a seating part adapted to be seated on an inner side surface of the discharge cover; and a pressing part arranged along a circumference of the seating part and adapted to push the dust collection container through elasticity thereof when the discharge cover is opened.

12. The dust collecting apparatus according to claim 11 , wherein the opening and closing member and the cover spacing member operate independently.

13. The dust collecting apparatus according to claim 11 , wherein the discharge cover comprises a unit seating portion allowing the cover spacing member to be seated thereon, wherein the unit seating portion is disposed closer to the one side of the discharge cover than to the other side of the discharge cover.

14. The dust collecting apparatus according to claim 11 , wherein the cover spacing member is disposed at the other side of the discharge cover with respect to the one side of the discharge cover pivotably hinged to the dust collection container.

15. The dust collecting apparatus according to claim 11 , wherein the discharge cover comprises a hinge adapted to be hinged to the dust collection container, wherein the hinge, the cover spacing member, and the catch member are disposed in the same line.

16. The dust collecting apparatus according to claim 11 , wherein the opening and closing member has a predetermined curvature.
