Abstract

A cleaner includes a dust bin, a motor housing disposed above and coupled to the dust bin, a handle coupled to the motor housing, a cyclone part disposed in the dust bin and configured to separate dust from air, a filter disposed in the dust bin and configured to filter air having separated the dust through the cyclone part, and a compression part configured to compress the dust in the dust bin. The compression part includes an operating part disposed in the motor housing and configured to move in a space between an outer portion of the filter part and an inner circumferential surface of the dust bin, a manipulation part disposed outside the motor housing and configured to be manipulated to move the operating part, and a transmission part that is disposed in the motor housing and connects the operating part and the manipulation part.

First claim

The invention claimed is:

1. A cleaner comprising:
a suction part configured to introduce air to the cleaner;
a motor configured to generate a suction force for introducing the air through the suction part;
a motor housing that accommodates the motor;
a handle coupled to the motor housing;
cyclone parts coupled to a lower side of the motor housing and configured to separate dust from the air introduced through the suction part;
a dust bin that accommodates the cyclone parts and is separably coupled to a lower portion of the motor housing, the dust bin being configured to store the dust;
a filter disposed in the dust bin and configured to filter air having separated the dust through the cyclone parts; and
a compression part configured to compress the dust stored in the dust bin,
wherein the compression part comprises:
an operating part disposed in the motor housing and configured to move along an up-down direction in a space defined between an outer portion of the filter and an inner circumferential surface of the dust bin,
a manipulation part disposed outside the motor housing and configured to be manipulated to translate relative to the handle to cause the operating part to move in the up-down direction, and
a transmission part that is disposed in the motor housing and connects the operating part to the manipulation part,

wherein the dust bin is configured to be separated from the motor housing and become disconnected from the motor housing,
wherein the operating part and the transmission part are configured to remain in the motor housing based on the dust bin being separated from the motor housing, and
wherein the manipulation part is configured to remain outside the motor housing based on the dust bin being separated from the motor housing.

2. The cleaner of claim 1 , wherein the compression part further comprises a compression rail disposed in the motor housing and configured to guide movement of the transmission part in the up-down direction.

3. The cleaner of claim 2 , wherein the dust bin is configured to be coupled to and separated from the motor housing in the up-down direction.

4. The cleaner of claim 3 , further comprising a sealing member configured to seal a gap between the dust bin and the motor housing.

5. The cleaner of claim 4 , wherein the sealing member is disposed at an upper end of the dust bin or a lower end of the motor housing.

6. The cleaner of claim 5 , further comprising a pipe connector that is configured to connect to the suction part,
wherein the cyclone parts comprise:
a first cyclone part that is in fluid communication with the pipe connector; and
a second cyclone part configured to separate dust from air discharged from the first cyclone part, and
wherein the filter surrounds the second cyclone part.

7. The cleaner of claim 6 , wherein the inner circumferential surface of the dust bin is spaced apart from an outer circumferential surface of the second cyclone part by an interval of 14 mm or more.

8. The cleaner of claim 7 , wherein each of the motor housing and the dust bin has a cylindrical shape,
wherein a width of the handle in a left-right direction is less than a diameter of each of the motor housing and the dust bin, and
wherein the manipulation part is configured to be spaced apart from a floor surface based on the motor housing, the dust bin, and the handle being in contact with the floor surface.

9. The cleaner of claim 1 , further comprising a pipe connector fixed to the motor housing and configured to couple to the suction part.

10. The cleaner of claim 9 , comprising:
a fastening part configured to couple the dust bin to the motor housing and to decouple the dust bin from the motor housing.

11. The cleaner of claim 10 , wherein the handle defines a groove configured to be coupled to the fastening part, and
wherein the fastening part comprises:
a button disposed below the pipe connector;
a hook disposed between the button and the dust bin and configured to rotate based on the button being pushed;
a first catching projection disposed at an outer surface of the dust bin and configured to be coupled to and decoupled from the hook based on rotation of the hook; and
a second catching projection disposed at a lower portion of the outer surface of the dust bin and disposed at a position opposite to the first catching projection, the second catching projection being configured to couple to the groove of the handle.

12. The cleaner of claim 11 , wherein the fastening part further comprises a rib configured to contact the hook based on rotation of the hook, and
wherein the hook comprises:
a first inclined surface configured to, based on the button moving relative to the rib, contact the rib to thereby rotate the hook in a clockwise direction; and
a second inclined surface that extends from the first inclined surface and is configured to move toward the rib based on the hook rotating in a counterclockwise direction.

13. The cleaner of claim 10 , further comprising a terminal disposed at the motor housing and disposed adjacent to the pipe connector, the terminal being configured to supply electricity to the suction part based on the suction part being coupled to the pipe connector.

14. The cleaner of claim 1 , further comprising a pipe connector fixed coupled to the dust bin and configured to couple to the suction part.

15. The cleaner of claim 14 , wherein the pipe connector is configured to be separated from the motor housing based on the dust bin being separated from the motor housing.

16. The cleaner of claim 14 , further a terminal disposed at the motor housing and disposed adjacent to the pipe connector, the terminal being configured to supply electricity to the suction part based on the suction part being coupled to the pipe connector.

17. The cleaner of claim 16 , wherein at least a portion of the dust bin supports the pipe connector.

18. The cleaner of claim 16 , wherein the pipe connector is attached to and supported by an outer circumferential surface of the dust bin.

19. The cleaner of claim 1 , further comprising a support portion that is disposed inside the dust bin and supports the cyclone parts.

20. A cleaner comprising:
a suction part configured to introduce air to the cleaner;
a motor configured to generate a suction force for introducing the air through the suction part;
a motor housing that accommodates the motor;
a handle coupled to the motor housing;
cyclone parts coupled to a lower side of the motor housing and configured to separate dust from the air introduced through the suction part;
a dust bin that accommodates the cyclone parts and is separably coupled to a lower portion of the motor housing, the dust bin being configured to store the dust;
a filter disposed in the dust bin and configured to filter air having separated the dust through the cyclone parts;
a pipe connector fixed to the motor housing and configured to couple to the suction part;
a fastening part configured to couple the dust bin to the motor housing and to decouple the dust bin from the motor housing; and
a compression part configured to compress the dust stored in the dust bin,
wherein the compression part comprises:
an operating part disposed in the motor housing and configured to move along an up-down direction in a space defined between an outer portion of the filter and an inner circumferential surface of the dust bin,
a manipulation part disposed outside the motor housing and configured to be manipulated to cause the operati
