Abstract

Disclosed is a cleaner. A dust accommodation container according to an embodiment of the present invention comprises a winding member. The winding member rotates inside the dust accommodation container and winds thin, long compressible waste, such as animal hair or fibers, which have flowed into the dust accommodation container. Accordingly, the space occupied inside the dust accommodation container by waste such as hair or fibers is reduced. Thus, the dust accommodation container can accommodate a larger amount of waste, and the operable time of the cleaner is greater. Consequently, user convenience can be enhanced.

First claim

What is claimed is:

1 . A cleaner comprising:
a housing having a collection space formed therein to accommodate collected dust or litter; a winding member rotatably disposed in the collection space, such that litter in a form of fur or fibers introduced into the collection space is wound around the winding member; and a gear unit provided to rotate the winding member, wherein the housing comprises:
a plurality of walls surrounding the collection space; and
a cover detachably coupled to the plurality of walls to open or close the collection space,
wherein the winding member comprises:
a base located adjacent to one of the plurality of walls, provided in a plate shape, and coupled to the gear unit; and
a winding rib continuous with the base, extending in a direction toward the cover, and rotating together with the base, and
wherein the winding rib is provided in plurality, disposed to be spaced apart from each other in a circumferential direction and are arranged radially based on a center of the base.

2 . The cleaner of claim 1 , wherein an extension length of the winding rib is shorter than a distance between the cover and the one wall adjacent to the base.

3 . The cleaner of claim 1 ,
wherein first winding ribs of the plurality of winding ribs are disposed adjacent to an outer circumference of the base and spaced apart from each other, and wherein second winding ribs of the plurality of winding ribs are disposed adjacent to the center of the base and spaced apart from each other.

4 . The cleaner of claim 3 , wherein the first winding ribs and the second winding ribs of the plurality of winding ribs extend by different lengths.

5 . The cleaner of claim 3 , wherein the first winding ribs and the second winding ribs of the plurality of winding ribs are alternately arranged along the outer circumference of the base.

6 . The cleaner of claim 1 ,
wherein the winding member is provided with a sealing member located between the base and the one wall and having a ring shape, and wherein the sealing member comes in contact with the base and the one wall, respectively.

7 . The cleaner of claim 6 , wherein the winding member is provided with a stepped portion located at a radially inner side of the sealing member between the base and the one wall, and having a cross-sectional area smaller than or equal to a cross-sectional area of a hollow portion formed inside the sealing member.

8 . The cleaner of claim 1 ,
wherein the gear unit comprises:
a transfer gear axially coupled to a motor to receive rotation of the motor; and
a rotation gear engaged with the transfer gear to receive rotation of the transfer gear, and axially coupled to the base to transfer rotational force to the winding member.

9 . The cleaner of claim 8 , wherein
the winding member is arranged as a plurality of winding members spaced apart from each other, and the plurality of winding members are each rotatably coupled to the gear unit.

10 . The cleaner of claim 8 , wherein
the winding member is arranged as a plurality of winding members spaced apart from each other, and at least one winding member of the plurality of winding members is coupled to the gear unit, and another winding member is rotatably engaged with the winding member coupled to the gear unit.

11 . A cleaner of claim 1 comprising:
a housing having a collection space formed therein to accommodate collected dust or litter;
a winding member rotatably disposed in the collection space, such that litter in a form of fur or fibers introduced into the collection space is wound around the winding member; and
a gear unit provided to rotate the winding member,
wherein the housing comprises:
a plurality of walls surrounding the collection space; and
a cover detachably coupled to the plurality of walls to open or close the collection space,

wherein the winding member comprises:
a base located adjacent to one of the plurality of walls, provided in a plate shape, and coupled to the gear unit; and
a winding rib continuous with the base, extending in a direction toward the cover, and rotating together with the base, and

wherein the winding rib comprises:
a first inclined portion connected to the base and extending in a direction opposite to the base;
a second inclined portion continuous with an end portion of the first inclined portion and extending in a direction opposite to the base to be inclined with respect to the first inclined portion; and
a third inclined portion continuous with an end portion of the second inclined portion and extending at a predetermined angle with the second inclined portion.

12 . The cleaner of claim 11 , wherein the second inclined portion extends obliquely in a direction toward a radially outer side of a central axis of the base.

13 . The cleaner of claim 11 , wherein the second inclined portion extends so that a distance from a central axis of the base is increased in the direction opposite to the base.

14 . The cleaner of claim 11 , wherein the predetermined angle formed between the third inclined portion and the second inclined portion is an obtuse angle.

15 . The cleaner of claim 11 , wherein an extension length of the first inclined portion is longer than extension lengths of the second inclined portion and the third inclined portion.

16 . A cleaner of claim 1 comprising:
a housing having a collection space formed therein to accommodate collected dust or litter;
a winding member rotatably disposed in the collection space, such that litter in a form of fur or fibers introduced into the collection space is wound around the winding member; and
a gear unit provided to rotate the winding member,
wherein the housing comprises:
a plurality of walls surrounding the collection space; and
a cover detachably coupled to the plurality of walls to open or close the collection space,

wherein the winding member comprises:
a base located adjacent to one of the plurality of walls and provided in a plate shape, and coupled to the gear unit; and
a winding rib continuous with the base and extending in a direction toward the cover and rotates together with the base, and

wherein the winding member is provided with a stepped portion located between the base and the one wall and having a cross-sectional area smaller than a cross-sectional area of the base.

17 . The cleaner of claim 16 ,
wherein the base is formed in a circular plate shape having a circular cross section and a thickness in a direction toward the one wall, wherein the stepped portion is formed in a plate shape having a circular cross section with the same center as a center of the cross section of the base, and a thickness in the direction toward the one wall, and wherein a diameter of the cross section of the stepped portion is smaller than a diameter of the cross section of the base.

18 . The cleaner of claim 16 ,
wherein the stepped portion comes in contact with the base and is disposed to be spaced apart from the one wall.
