Abstract

A cleaner includes a hollow cylindrical housing; a housing wall dividing an internal space of the housing into a first space and a second space; a wall through-hole defined to pass through the housing wall; a mounting portion including a mounting body having a top face and a mounting space defined therein in communication with the second space, the mounting body being fixed into the wall through-hole; first openings defined in a first region of the bottom face, and second openings defined in a second region of the bottom face; a separator disposed in the first space to form a flow path for guiding air to the plurality of openings, and a filter that includes a filter body located in the mounting space, and filter faces to filter the air flowing through the first openings and second openings.

First claim

What is claimed is:

1. A cleaner comprising:
a hollow housing;
a wall dividing an internal space of the housing into a first space and a second space;
a through-hole defined to pass through the wall;
a mount including:
a mounting body having a top face and a mounting space defined therein in communication with the second space, wherein the mounting body is coupled to the through-hole;
at least one first opening penetrating a bottom face of the mounting body and in communication with the mounting space, wherein the first opening is defined in a first region of the bottom face that is a region including a center of the bottom face of the mounting body; and
at least one second opening penetrating the bottom face and in communication with the mounting space, wherein the second opening is defined in a second region of the bottom face that is separated from the first region and defined as a ring-shaped region surrounding the first region;
an intake port, the first space communicating with an exterior of the housing via the intake port;
an exhaust hole, the second space communicating with the exterior of the housing via the exhaust hole;
a separator positioned in the first space to form a flow path to guide air flowing from the intake port to the first and second openings, wherein the separator removes material from the air using centrifugal force;
a fan positioned in the second space to move air from the first and second openings to the exhaust hole; and
a filter positioned in the mount to filter air flowing to the fan,

wherein the filter includes:
a cup-shaped filter body located in the mounting space;
a first filter face positioned to face the bottom face of the mounting body to filter air flowing through the first opening; and
a second filter face positioned on the filter body to divide the mounting space into a first space adjacent to the first region and a second space adjacent to the second region, wherein the second filter face filters air flowing through the second opening,

wherein the second opening includes at least two communicating holes, and
wherein the second filter face includes chamber forming walls provided on a side face of the filter body to form, respectively, filtering chambers, a quantity of the filtering chambers formed by the chamber forming walls being equal to a quantity of communicating holes in the mounting space.

2. The cleaner of claim 1 , wherein the filtering chambers are provided to define respective spaces that are independent of each other.

3. The cleaner of claim 1 , wherein each of the chamber forming walls is shaped to be bent toward a center of the filter body.

4. The cleaner of claim 3 , further comprising one or more guides positioned in the mount to divide each of the filtering chambers into at least two spaces,
wherein pairs of the communicating holes included in the second opening are separated from each other by one of the guides.

5. The cleaner of claim 1 , wherein the second opening includes a first communicating hole, a second communicating hole, and a third communicating hole,
wherein the second filter face includes:
a first chamber forming wall that is bent toward a center of the filter body to form a first filtering chamber in communication with the first communicating hole in the mounting space and not in communication with the second and third communicating holes;
a second chamber forming wall that is bent toward the center of the filter body to form a second filtering chamber in communication with the second communicating hole in the mounting space and not in communication with the first and third communicating holes; and
a third chamber forming wall that is bent toward the center of the filter body to form a third filtering chamber in communication with the third communicating hole in the mounting space and not in communication with the first and second communicating holes.

6. The cleaner of claim 5 , further comprising:
a first guide positioned to divide the first filtering chamber into at least two spaces;
a second guide positioned to divide the second filtering chamber into at least two spaces; and
a third guide positioned to divide the third filtering chamber into at least two spaces,
wherein the first communicating hole includes at least two holes provided respectively in the spaces defined in the first filtering chamber by the first guide,
wherein the second communicating hole includes at least two holes provided respectively in the spaces defined in the second filtering chamber by the second guide, and
wherein the third communicating hole includes at least two holes provided respectively in the spaces separated defined in the third filtering chamber by the third guide.

7. The cleaner of claim 5 , wherein the second opening further includes a fourth communicating hole, and
wherein the second filter face further includes a fourth chamber forming wall that is bent toward the center of the filter body to form a fourth filtering chamber in communication with the fourth communicating hole in the mounting space and not in communication with the first, second, and third communicating holes.

8. The cleaner of claim 7 , wherein the fourth filtering chamber is positioned independent of the first filtering chamber, the second filtering chamber, and the third filtering chamber.

9. The cleaner of claim 7 , further comprising:
a first guide positioned to divide the first filtering chamber into at least two spaces;
a second guide positioned to divide the second filtering chamber into at least two spaces;
a third guide positioned to divide the third filtering chamber into at least two spaces; and
a fourth guide positioned to divide the fourth filtering chamber into at least two spaces,
wherein the first communicating hole includes at least two holes separated from each other by the first guide,
wherein the second communicating hole includes at least two holes separated from each other by the second guide,
wherein the third communicating hole includes at least two holes separated from each other by the third guide, and
wherein the fourth communicating hole includes at least two holes separated from each other by the fourth guide.

10. The cleaner of claim 7 , wherein the second opening further includes a fifth communicating hole,
wherein the second filter face further includes a fifth chamber forming wall bent toward the center of the filter body to form a fifth filtering chamber in communication with the fifth communicating hole in the mounting space and not in communication with the first, second, third, and fourth communicating holes.

11. The cleaner of claim 10 , further comprising:
a first guide positioned to divide the first filtering chamber into at least two spaces;
a second guide positioned to divide the second filtering chamber into at least two spaces;
a third guide positioned to divide the third filtering chamber into at least two spaces;
a fourth guide positioned to divide the fourth filtering chamber into at least two spaces; and
a fifth guide positioned to divide the fifth filtering chamber into at least two spaces,
wherein the first communicating hole includes at least two holes separated from each other by the first guide,
wherein the second communicating hole includes at least two holes separated from each other by the second guide,
wherein the third communicating hole includes at least two holes separated from each other by the third guide,
wherein the fourth communicating hole includes at least two holes separated from each other by the fourth guide, and
wherein the fifth communicating hole includes at least two holes separated from each other by the fifth guide.
