Abstract

A vacuum cleaner including a housing having a dust collection chamber; a main body that is movable against the housing between a first position and a second position; a rubbish removal member in the dust collection chamber; and an opening or closing device. When the main body is moved against the housing from the first position to the second position, the opening or closing device opens the dust collection chamber, and the rubbish removal member moves toward an open end of the dust collecting chamber to allow rubbish removed by the rubbish removal member to be discharged out of the dust collection chamber. When the main body is moved against the housing from the second position to the first position, the rubbish removal member moves toward an inside of the dust collection chamber, and the opening or closing device closes the dust collection chamber.

First claim

What is claimed is:

1 . A vacuum cleaner comprising:
a housing having a dust collection chamber inside the housing; a main body that is movable against the housing between a first position and a second position; a guide device between the housing and the main body, and including a roller to guide movement of the main body against the housing; a rubbish removal member in the dust collection chamber; and an opening or closing device to open or close the dust collection chamber, wherein the main body, the guide device, the rubbish removal member, and the opening or closing device are configured so that,
when the main body is moved against the housing from the first position to the second position, the opening or closing device opens the dust collection chamber, and the rubbish removal member moves toward an open end of the dust collecting chamber to allow rubbish removed by the rubbish removal member to be discharged out of the dust collection chamber, and
when the main body is moved against the housing from the second position to the first position, the rubbish removal member moves away from the open end of the dust collection chamber toward an inside of the dust collection chamber, and the opening or closing device closes the dust collection chamber.

2 . The vacuum cleaner of claim 1 , wherein the roller protrudes from a surface of the guide device facing the main body toward the main body.

3 . The vacuum cleaner of claim 2 , wherein the roller has a rotation axis perpendicular to a moving direction of the main body.

4 . The vacuum cleaner of claim 2 , wherein the roller is arranged to roll on an outer surface of the main body.

5 . The vacuum cleaner of claim 2 , wherein the guide device includes a body rotationally supporting the roller.

6 . The vacuum cleaner of claim 1 , wherein the guide device includes a plurality of rollers equidistantly spaced apart from each other along an outer circumference of the main body.

7 . The vacuum cleaner of claim 1 , wherein the guide device further includes a stopper to limit movement of the main body to an opposite direction from a direction toward the first position in response to the main body being in the second position.

8 . The vacuum cleaner of claim 7 , wherein the stopper includes a buffer material.

9 . The vacuum cleaner of claim 7 , wherein
the main body includes a battery installation portion in which a battery is mounted, and the stopper is arranged to support the battery installation portion in response to the main body being in the second position.

10 . The vacuum cleaner of claim 9 , wherein the battery installation portion is in the housing.

11 . The vacuum cleaner of claim 1 , wherein the guide device is provided in the singular, or in the plural at certain intervals in a moving direction of the main body.

12 . The vacuum cleaner of claim 1 , wherein the housing includes a guide installation portion on an inner surface of the housing to which the guide device is installed so as to be fixed to the housing.

13 . The vacuum cleaner of claim 1 , wherein
the dust collection chamber is a first dust collection chamber, the vacuum cleaner includes a rubbish separation device to remove rubbish from air having passed the first dust collection chamber, and the housing has a second dust collection chamber inside the housing for collecting rubbish separated from the rubbish separation device.

14 . The vacuum cleaner of claim 13 , wherein
the rubbish removal member is a first rubbish removal member, and the vacuum cleaner includes a second rubbish removal member arranged to slide on the second dust collection chamber and the first dust collection chamber to discharge rubbish from the second dust collection chamber in response to the main body moving from the first position to the second position.

15 . A vacuum cleaner comprising:
a housing having a dust collection chamber inside the housing; a main body that is movable against the housing between a first position and a second position; a guide device between the housing and the main body, fixed to the housing, and including a roller protruding toward the main body so as to roll on an outer surface of the main body to guide movement of the main body against the housing; a rubbish removal member in the dust collection chamber; and an opening or closing device to open or close the dust collection chamber, wherein the main body, the guide device, the rubbish removal member, and the opening or closing device are configured so that,
when the main body is moved against the housing from the first position to the second position, the opening or closing device opens the dust collection chamber, and the rubbish removal member moves toward an open end of the dust collecting chamber to allow rubbish removed by the rubbish removal member to be discharged out of the dust collection chamber, and
when the main body is moved against the housing from the second position to the first position, the rubbish removal member moves away from the open end of the dust collection chamber toward an inside of the dust collection chamber, and the opening or closing device closes the dust collection chamber.
