Abstract

Provided is a vacuum cleaner including a cleaner body; a dust container installed at the cleaner body and of which at least a part is exposed to an outside through a front surface of the cleaner body; a cover member installed to open and close a part of the cleaner body and configured to selectively accommodate an upper portion of the dust container; a suction hose of which one side is connected to a suction part for suctioning dust and the other side is connected to a front end of the cover member; a grip portion provided at the cover member and operated to open and close the cover member; and a locking assembly provided inside the cover member and disposed at both sides based on the suction part to be restricted in the cleaner body.

Claims

1. A vacuum cleaner comprising:

a cleaner body;

a dust container that is located at the cleaner body, at least a portion of the dust container being exposed to an outside of the cleaner body through a front surface of the cleaner body;

a cover member that is connected to the cleaner body and that is configured to selectively cover an upper portion of the dust container;

a suction hose that is configured to receive dust through a suction part at one end and that is connected to a front end of the cover member at the other end;

a grip portion that is located at the cover member and that is configured to be gripped by a user to open and close the cover member; and

a locking assembly that is located inside the cover member and that is configured to selectively lock the cover member to the cleaner body or release the cover member from the cleaner body.

2. The vacuum cleaner according to claim 1, wherein

the front surface of the cleaner body includes an open space in which the dust container is located, and

the cover member includes a cover coupling portion that extends from a rear end of the cover member and that is rotatably coupled to the cleaner body.

3. The vacuum cleaner according to claim 1, wherein the locking assembly is configured to laterally protrude outward from both side surfaces of the cover member based on a user'"'"'s operation to become selectively restricted to the cleaner body.

4. The vacuum cleaner according to claim 1, wherein the cover member comprises:

a cover base that is configured to cover an upper surface of the cleaner body; and

an outer cover that is coupled to the cover base, that defines an exterior of the vacuum cleaner, and that defines a space for accommodating the locking assembly.

5. The vacuum cleaner according to claim 4, wherein the grip portion is coupled to the outer cover.

6. The vacuum cleaner according to claim 5, wherein the grip portion includes a push member that is configured to operate the locking assembly based on a user'"'"'s operation.

7. The vacuum cleaner according to claim 3, wherein the cleaner body defines a protrusion restricting hole at an inside surface of the cleaner body that is configured to correspondingly receive the laterally protruding portions of the locking assembly.

8. The vacuum cleaner according to claim 1, wherein the locking assembly comprises:

a push member that is configured to open or close an opening and closing member based on a user'"'"'s operation;

a main link that is located below the push member and that is configured to rotate based on the push member being pushed down by the user'"'"'s operation; and

a sub-link that is connected to an end of the main link, that is configured to reciprocate linearly based on the rotation of the main link, and that is configured to selectively protrude to an outside of the cover member.

9. The vacuum cleaner according to claim 8, wherein the main link includes:

a through portion that is configured to be shaft-coupled to the opening and closing member;

a first extending portion that extends from the through portion toward the push member and that is configured to move based on the push member being pushed down; and

a second extending portion that extends from the through portion in a direction intersecting with the first extending portion, an extended end of the second extending portion being rotatably connected to the sub-link.

10. The vacuum cleaner according to claim 9, wherein the locking assembly includes a pair of the main links, the first extending portion of each main link being aligned to each other and overlapping with each other at an end of the first extending portion, and wherein an extending portion inclined surface is provided at a surface of the first extending portion that is configured to contact the push member.

11. The vacuum cleaner according to claim 8, wherein the push member is located at a grip portion body of the grip portion, configured to move up or down based on a user'"'"'s operation, and configured to maintain a protruded state by having an elastic member support.

12. The vacuum cleaner according to claim 11, wherein the locking assembly comprises a transmission member that is connected to a lower portion of the push member and that is configured to rotate the main link based on the transmission member contacting the main link.

13. The vacuum cleaner according to claim 12, wherein the grip portion includes a transmission member guide that is configured to guide the transmission member toward the main link.

14. The vacuum cleaner according to claim 13, wherein a lower end of the transmission member includes:

a guide inclined surface that is in contact with the transmission member guide, that slopes from a vertical section of the transmission member, and that is configured to guide the transmission member toward the main link; and

a transmission member inclined portion that intersects the guide inclined surface at the lower end of the transmission member, that is configured to contact the main link, and that is configured to rotate the main link based on contacting the main link.

15. The vacuum cleaner according to claim 12, wherein the transmission member includes a pair of separation preventing protrusions at an upper end of the transmission member, and

the push member includes a separation preventing rib that is located between the pair of separation preventing protrusions and that is configured to limit rotation of the transmission member.

16. The vacuum cleaner according to claim 8, wherein the cover member defines:

a protrusion entrance at a side surface that is configured to receive an end of the sub-link that protrudes outward from an inside of the cover member; and

a link guide that extends from an inner surface of the cover member, that is configured to receive the sub-link, and that is configured to guide movement of the sub-link toward the protrusion entrance.

17. The vacuum cleaner according to claim 8, wherein the sub-link includes:

a third extending portion that is shaft-coupled to the main link and that extends laterally toward an outer surface of the vacuum cleaner;

a fourth extending portion that extends downward from an end of the third extending portion; and

a cover restricting protrusion that extends from and end of the fourth extending portion toward the outer surface of the vacuum cleaner and that protrudes through the cover member.

18. The vacuum cleaner according to claim 8, wherein the sub-link includes a cover restricting protrusion that protrudes to an outside of the cover member through a protrusion restricting hole at a surface of the cleaner body and that includes an inclined surface that is configured to contact the cleaner body.
