Abstract

A cleaner includes: a main body that forms an external shape; a dust container that is separably combined with the main body and stores dust separated from air; a dust container cover that is configured to open and close the dust container; a handle unit that is disposed behind the dust container; and an operating member that is configured to provide operation force to the dust container cover by moving in a first direction and to release a holding mechanism for preventing separation of the dust container from the main body by moving in a second direction opposite to the first direction.

First claim

What is claimed is:

1. A cleaner comprising:
a main body including:
a suction unit configured to guide suctioned air including dust,
a first cyclone unit configured to separate the dust from the suctioned air,
a second cyclone unit provided in a space defined by the first cyclone unit and configured to separate dust from air discharged from the first cyclone unit,
a dust container configured to store the dust separated from the first and second cyclone units,
a dust container cover configured to open and close the dust container; and
a suction motor that is configured to generate suction force to thereby suction air and that is located above the second cyclone unit with respect to a center axis of cyclone flow of the second cyclone unit;

a handle unit connected to the main body and including a handle and a battery housing provided at a lower side of the handle and configured to receive a battery; and
an operating member configured to operate the dust container cover to be rotated,
wherein the dust container is positioned opposite to the suction motor with respect to the second cyclone unit, and
wherein a hinge for rotating of the dust container cover is positioned opposite to the battery housing with respect to a center axis of cyclone flow of the first cyclone unit.

2. The cleaner of claim 1 , wherein the dust container cover includes a locking hook to be locked to the dust container,
the locking hook is positioned between the center axis of cyclone flow of the first cyclone unit and the battery housing in a state in which the locking hook is locked to the dust container, and
the dust container cover is rotated in a direction where the locking hook is moved away from the battery housing to open the dust container.

3. The cleaner of claim 1 , wherein the handle unit is slidably connected to the main body.

4. The cleaner of claim 1 , wherein the handle unit further includes a connecting body that connects the handle to the battery housing,
the connecting body includes a slot, and
the operation member is disposed between the dust container and the connecting body and includes an operating rib that passes through the slot and extends toward the handle.

5. The cleaner of claim 4 , wherein the operating rib is positioned higher than the dust container, and
the operation member further includes a transferring member configured to transfer operating force of the operating rib to the dust container cover.

6. The cleaner of claim 4 , wherein the handle includes a first extension that extends in up and down directions, and a second extension that extends toward the main body from an upper portion of the first extension, and
the operating rib extends toward the first extension.

7. The cleaner of claim 6 , wherein the operating rib is closer to the battery housing than the second extension.

8. The cleaner of claim 6 , wherein the operating rib is positioned between the first extension and the center axis of cyclone flow of the first cyclone unit.

9. The cleaner of claim 6 , wherein the suction unit is configured to guide the suction air including the dust to the first cyclone unit and has a longitudinal axis that passes through the first extension, and
wherein the operating rib is positioned opposite to the suction unit with respect to the center axis of cyclone flow of the first cyclone unit.

10. The cleaner of claim 1 , further comprising an elastic member configured to provide an elastic force to the operation member to be returned an initial position after the operation member is operated.

11. The cleaner of claim 10 , wherein the elastic member includes a coil spring, and provides the elastic force to the operation member in a direction parallel to the center axis of cyclone flow of the first cyclone unit.

12. The cleaner of claim 1 , wherein the handle includes (i) a first extension that extends in an upward direction and that is inclined from the battery housing and (ii) a second extension that extends from the first extension toward the suction motor.

13. The cleaner of claim 12 , wherein the handle unit further includes a connecting body that connects the second extension to the battery housing.

14. The cleaner of claim 13 , further comprising a filter configured to filter air that has passed the suction motor, and
wherein the filter is disposed opposite to the second extension with respect to the connecting body.

15. The cleaner of claim 1 , wherein the handle unit further includes a connecting body that connects the handle to the battery housing, and
wherein the suction motor faces a first surface of the connecting body, and the battery housing is located at an opposite side of the first surface of the connecting body.

16. The cleaner of claim 1 , further comprising a filter configured to filter air that has passed the suction motor, and
wherein at least a portion of the filter is disposed above an upper end of the suction motor.

17. The cleaner of claim 1 , further comprising a filter configured to filter air that has passed the suction motor,
wherein the handle unit further includes a connecting body that connects the handle to the battery housing, and
wherein a portion of the handle is disposed opposite to the filter with respect to the connecting body.

18. The cleaner of claim 1 , further comprising a filter configured to filter air that has passed the suction motor, and
wherein the suction motor overlaps the filter with respect to the center axis of cyclone flow of the first cyclone unit.

19. The cleaner of claim 1 , further comprising a filter configured to filter air that has passed the suction motor, the filter being configured to separate from the main body in an upward direction.

20. A cleaner comprising:
a main body including:
a suction unit configured to guide suctioned air including dust,
a first cyclone unit configured to separate the dust from the suctioned air,
a second cyclone unit configured to separate dust from air discharged from the first cyclone unit,
a dust container configured to store the dust separated from the first and second cyclone units,
a dust container cover configured to open and close the dust container, and
a suction motor that is configured to generate suction force to thereby suction air and that is located above the second cyclone unit with respect to a center axis of cyclone flow of the second cyclone unit;

a handle unit connected to the main body and including (i) a handle, (ii) a battery housing that is provided at a lower side of the handle and that is configured to receive a battery, and (iii) a connecting body that connects the handle to the battery housing; and
an operating member configured to operate the dust container cover to be rotated,
wherein the connecting body includes a slot, and
wherein the operation member is disposed between the dust container and the connecting body and includes an operating rib that passes through the slot and that extends toward the handle.
