Abstract

A vacuum cleaner includes a cleaner body and a dust container separably mounted on the cleaner body. The dust container includes a dust collection body including an opening, a wall, and a dust separation part. A cover covers the opening of the dust collection body. An air guide is disposed at the dust collection body, the air guide having an opening provides an inflow hole through which air separated from dust in the dust separation part is introduced, and a filter accommodated in the air guide filters the air separated from the dust. When the cover uncovers the opening of the dust collection body, the filter is visible through the opening of the air guide.

First claim

What is claimed is:

1. A vacuum cleaner comprising:
a cleaner body; and
a dust container separably mounted at the cleaner body,
wherein the dust container comprises:
a dust collection body comprising a first opening and a wall, the dust collection body comprising a dust separation part;
a cover covering the first opening of the dust collection body;
an air guide comprising a second opening and an end, the air guide having the end disposed at the wall of the dust collection body, the second opening of the air guide providing an inflow hole through which air separated from dust in the dust separation part is introduced; and
a filter accommodated in the air guide to filter the air separated from the dust,
wherein when the cover uncovers the first opening of the dust collection body, the filter is visible through the second opening of the air guide.

2. The vacuum cleaner according to claim 1 , wherein a third opening is defined at the wall of the dust collection body, and the filter is insertable or withdrawable from the air guide through the third opening.

3. The vacuum cleaner according to claim 2 , further comprising a filter supporter to support the filter, the filter supporter coupleable to the wall of the dust collection body through the third opening,
wherein the filter supporter comprises a discharge hole through which the air passing through the filter is discharged.

4. The vacuum cleaner according to claim 3 , wherein the filter is hollow with a fourth opening, and
the filter supporter comprises a support rib insertable into the fourth opening of the filter.

5. The vacuum cleaner according to claim 3 , wherein the third opening of the dust collection body comprises a protrusion part to couple the filter supporter to the wall of the dust collection body, and
a coupling rib at which the protrusion part couples is disposed at the filter supporter.

6. The vacuum cleaner according to claim 1 , wherein an upper portion of the filter protrudes from the inflow hole of the air guide and is disposed higher than the inflow hole of the air guide.

7. The vacuum cleaner according to claim 1 , wherein the air guide comprises an upper wall having the inflow hole, and
a top surface of the filter accommodated at the air guide is spaced apart from the upper wall of the air guide.

8. The vacuum cleaner according to claim 1 , wherein a portion of the air separated from the dust at the dust separation part passes through the filter exposed from the air guide, and an another portion of the air is introduced into an air passage between the air guide and the filter to pass through the filter.

9. The vacuum cleaner according to claim 1 , wherein the dust collection body comprises a first wall and a second wall to partition an inner space of the first wall into a first dust storage part and a second dust storage part,
the dust separation part is disposed above the second dust storage part, and
the air guide is disposed at least within the second dust storage part.

10. The vacuum cleaner according to claim 9 , wherein when the cover uncovers the first opening of the dust collection body, an inside of the first dust storage part and the second dust storage part are visible.

11. The vacuum cleaner according to claim 9 , wherein the second wall of the dust collection body comprises a communication hole through which dust within the second dust storage part is movable to the first dust storage part.

12. The vacuum cleaner according to claim 1 , wherein the dust collection body comprises a main wall to define the dust separation part and a second dust storage part, and an auxiliary wall that surrounds the main wall to define a first dust storage part,
the dust separation part is disposed above the second dust storage part, and
the air guide is disposed within at least the second dust storage part.

13. The vacuum cleaner according to claim 12 , wherein the main wall of the dust collection body comprises a communication hole through which the dust within the second dust storage part is movable to the first dust storage part.

14. A vacuum cleaner comprising:
a cleaner body; and
a dust container separably mounted at the cleaner body,
wherein the dust container comprises:
a dust collection body comprising a wall and a dust separation part, the wall of the dust collection body comprising an opening;
an air guide comprising an inflow hole and an end, the end of the air guide disposed at the wall of the dust collection body;
a filter accommodated at the air guide to filter the air separated from the dust,
wherein an air passage through which the air introduced through the inflow hole flows is defined between the air guide and the filter,
wherein the air passing through the air passage and through the filter is discharged through the opening of the wall of the dust collection body.

15. The vacuum cleaner according to claim 14 , further comprising a filter supporter to support the filter, wherein the filter supporter comprises at least one hole through which the air passing through the filter passes.

16. The vacuum cleaner according to claim 14 , wherein the dust container further comprises a cover to cover the dust collection body, and
when the cover uncovers the dust collection body, the filter is visible through the inflow hole of the air guide.

17. The vacuum cleaner according to claim 15 , wherein the filter supporter is inserted into the filter and the filter supporter is coupleable to the wall of the dust collection body through the opening.
