Abstract

Provided is a cleaner. The cleaner includes a housing provided with a dust container at a lower side thereof having a suction opening, a filter part configured to filter dust from air suctioned through the suction opening, the filter being spaced apart from an inner circumferential surface of the housing, a movable part configured to be elevated between a first position and a second position in a space between the outside of the filter part and the inner circumferential surface of the housing, a manipulation part of which at least a portion is exposed to outside of the housing, the manipulation part being elevated by user's manipulation, and a transfer unit of which at least a portion is accommodated in the housing, the transfer unit being configured to connect the manipulation part to the movable part. The dust container has an elevation groove, which is recessed outward from an inner surface of the dust container, in a vertical direction.

First claim

What is claimed is:

1. A cleaner comprising:
a housing having an upper side and a lower side, the lower side defining a dust container with a suction opening formed therein;
a filter part configured to filter particles from air suctioned through the suction opening, the filter being spaced apart from an inner surface of the housing;
a movable part provided in a space located between an outer surface of the filter part and the inner surface of the housing, the moveable part configured to be elevated between a first position and a second position;
a manipulation part having at least a portion thereof that is exposed outside of the housing, the manipulation part configured to be moved by a user's manipulation; and
a transfer unit having at least a portion thereof that is accommodated inside the housing, the transfer unit configured to connect the manipulation part to the movable part,
wherein the dust container has an elevation groove formed therein, the elevation groove extending in a vertical direction and recessed outward from an inner surface of the dust container, and
wherein a partition member provided at an inlet-side of the elevation groove to partition an inner space of the dust container from an inner surface of the elevation groove, and
wherein the partition member has a slit extending in a vertical direction, and
wherein the slit is selectively opened and closed by an elevation operation of the connection part.

2. The cleaner according to claim 1 , wherein the transfer unit comprises:
a first transfer part and a second transfer part,
wherein the first transfer part is configured to connect an upper side of the second transfer part to an upper side of the manipulation part, and
wherein the second transfer part extends upward from one side of the movable part.

3. The cleaner according to claim 2 , wherein, when the movable part is elevated, at least a portion of the second transfer part is accommodated into and guided by the elevation groove.

4. The cleaner according to claim 3 , wherein the slit is configured to receive the movable part and the connection part of the second transfer part.

5. The cleaner according to claim 4 , wherein the slit closes when the connection part descends, and the slit opens when the connection part ascends.

6. The cleaner according to claim 4 , wherein the partition member comprises a cushion material having elasticity.

7. The cleaner according to claim 4 , wherein the partition member comprises a brushed material.

8. The cleaner according to claim 4 , wherein the partition member comprises a rubber or silicon material.

9. The cleaner according to claim 4 , wherein the partition member is provided at each side of the inlet-side of the elevation groove,
wherein end portions of the partition member in which the slit is defined at least partially overlap each other.

10. The cleaner according to claim 4 , wherein the partition member is provided at each side of the inlet-side of the elevation groove,
wherein end portions of the partition member in which the slit is defined at least partially contact each other.

11. The cleaner according to claim 1 , wherein the portion of the manipulation part that is exposed outside of the housing extends in a horizontal direction.

12. The cleaner according to claim 1 , further comprising an elastic member configured to provide an elastic force to the manipulation part or the transfer unit.

13. The cleaner according to claim 12 , wherein the elastic force provided by the elastic member pushes the manipulation part upward.

14. The cleaner according to claim 13 , wherein a support bar extending vertically is provided outside of the housing, and
the elastic member is inserted into an outer circumferential surface of the support bar.

15. The cleaner according to claim 1 , wherein a handle part is disposed outside of the housing, and
the manipulation part is disposed adjacent to one side of the handle part.

16. The cleaner according to claim 1 , wherein the slit closes when the connection part descends, and the slit opens when the connection part ascends.

17. A cleaner comprising:
a housing having an upper side and a lower side, the lower side defining a dust container with a suction opening formed therein;
a filter part configured to filter particles from air suctioned through the suction opening, the filter being spaced apart from an inner surface of the housing;
a movable part provided in a space located between an outer surface of the filter part and the inner surface of the housing, the moveable part configured to be elevated between a first position and a second position;
a manipulation part having at least a portion thereof that is exposed outside of the housing, the manipulation part configured to be moved by a user's manipulation;
a transfer unit having at least a portion thereof that is accommodated inside the housing, the transfer unit configured to connect the manipulation part to the movable part, the transfer unit comprising a first transfer part and a second transfer part, the first transfer part configured to connect an upper side of the second transfer part to an upper side of the manipulation part, and the second transfer part extending upward from one side of the movable part;
an elevation groove formed in the dust container, the elevation groove extending in a vertical direction and recessed outward from an inner surface of the dust container; and
a partition member provided at an inlet side of the elevation groove to partition an inner space of the dust container from an inner surface of the elevation groove, the partition member having a slit extending in a vertical direction, the slit configured to receive the movable part and the connection part of the second transfer part,
wherein the slit is selectively opened and closed by an elevation operation of the connection part.
