Abstract

A dust collecting apparatus includes a dust separation unit to separate dust from suctioned air; a dust storage unit to store the dust separated in the dust separation unit; a pressing member to compress the dust stored in the dust storage unit, and having a pressing plate support part, and a pressing plate supported by the pressing plate support part; a fixing member disposed between an inner circumferential surface of the dust storage unit and the pressing plate support part; and a path formed by a part of the fixing member, located between the pressing plate support part and the inner circumferential surface of the dust storage unit, and through which the air between the pressing plate and the fixing member passes, wherein one or more holes through which the air between the pressing plate and the fixing member passes are formed at the pressing plate.

First claim

What is claimed is:

1 . A dust collecting apparatus comprising:
a dust separation unit configured to separate dust from suctioned air; a dust storage unit configured to store the dust separated in the dust separation unit; a pressing member configured to compress the dust stored in the dust storage unit, and having a pressing plate support part, and a pressing plate supported by the pressing plate support part; a fixing member disposed between an inner circumferential surface of the dust storage unit and the pressing plate support part; and a path formed by a part of the fixing member, located between the pressing plate support part and the inner circumferential surface of the dust storage unit, and through which the air between the pressing plate and the fixing member passes, wherein one or more holes through which the air between the pressing plate and the fixing member passes are formed at the pressing plate.

2 . The apparatus of claim 1 , wherein a plurality of holes are formed at the pressing plate, and the plurality of holes are disposed to be vertically and horizontally spaced apart from each other.

3 . The apparatus of claim 2 , wherein the fixing member comprises a path forming part which forms the path, and the path is formed between the path forming part and the dust storage unit.

4 . The apparatus of claim 3 , wherein a width of a portion of the fixing member at which the path forming part is formed is formed smaller than that of a portion thereof at which the path forming part is not formed.

5 . The apparatus of claim 2 , wherein a maximum width of the path is larger than a diameter of the one or more holes.

6 . The apparatus of claim 5 , wherein an entire area of the plurality of holes is larger than an area of the path.

7 . The apparatus of claim 1 , wherein the entire fixing member is spaced apart from the inner circumferential surface of the dust storage unit.

8 . The apparatus of claim 1 , further comprising a flow restriction part which restricts rising of the air in the dust storage unit.

9 . The apparatus of claim 8 , further comprising a filter unit which filters the air separated from the dust in the dust storage unit,
wherein the flow restriction part is provided at the filter unit.

10 . The apparatus of claim 9 , wherein the filter unit comprises a filter body having one or more holes through which the air passes, and
the flow restriction part extends spirally along a circumference of an outer circumferential surface of the filter body.

11 . The apparatus of claim 9 , wherein the flow restriction part extends from the inner circumferential surface of the dust storage unit.

12 . The apparatus of claim 9 , wherein a diameter of the dust storage unit is formed larger than that of the dust separation unit, and the dust storage unit and the dust separation unit are connected by a connection part, and at least a part of the flow restriction part is located lower than the connection part.

13 . The apparatus of claim 12 , wherein the connection part is disposed horizontally or disposed to be inclined at an angle less than 90 degrees.

14 . A dust collecting apparatus comprising:
a dust separation unit configured to separate dust from suctioned air; a filter unit configured to filter the air separated from the dust in the dust separation unit; a dust storage unit configured to store the dust separated from the air in the dust separation unit, and of which an upper portion has a diameter larger than a diameter of a lower portion of the dust separation unit; a connection part configured to connect the dust storage unit with the dust separation unit; a pressing member configured to compress the dust stored in the dust storage unit, and having a pressing plate support part, and a pressing plate supported by the pressing plate support part; a fixing member disposed between an inner circumferential surface of the dust storage unit and the pressing plate support part; and a dust movement guide configured to guide movement of the dust so that the dust separated in the dust separation unit smoothly falls down into the dust storage unit, wherein at least a part of the dust movement guide is located lower than the connection part.

15 . The apparatus of claim 14 , wherein the dust movement guide spirally extends along a circumference of an outer circumferential surface of the filter unit.

16 . The apparatus of claim 14 , wherein the dust movement guide protrudes from the inner circumferential surface of the dust storage unit.

17 . The apparatus of claim 16 , wherein the dust movement guide is located higher than the fixing member and the pressing plate.

18 . The apparatus of claim 17 , wherein at least a part of the dust movement guide is disposed to be vertically overlapped with the fixing member.

19 . A dust collecting apparatus comprising:
a first dust separation unit configured to primarily separate dust from suctioned air; a first dust storage unit configured to store the dust separated in the first dust separation unit; a pressing member configured to compress the dust stored in the first dust storage unit, and having a pressing plate support part, and a pressing plate supported by the pressing plate support part; a fixing member disposed between an inner circumferential surface of the first dust storage unit and the pressing plate support part; a second dust separation unit configured to separate again the dust from the air passed through a dust separation process in the first dust separation unit; and a flow restriction part configured to protrude from the dust storage unit and to restrict rising of the air stored in the dust storage unit.

20 . The apparatus of claim 20 , wherein the flow restriction part extends spirally along the inner circumferential surface of the dust storage unit.

21 . The apparatus of claim 20 , wherein at least a part of the flow restriction part is disposed to be vertically overlapped with the fixing member.

22 . The apparatus of claim 20 , further comprising a path formed by a part of the fixing member, located between the pressing plate support part and the inner circumferential surface of the dust storage unit, and through which the air between the pressing plate and the fixing member passes.

23 . The apparatus of claim 19 , wherein the fixing member stores the dust separated in the second dust separation unit.
