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.

Dependent claims

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;
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;
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.

A cleaner comprising:

a housing having an intake port and an exhaust port;
a fan provided in the housing to generate an air flow into the housing through the intake port and out of the housing via the exhaust port;
a separator provided in the housing and including a plurality of flow path bodies that extend in an axial direction of the housing to generate a plurality of cyclones to remove material from air flowing from the intake port, the plurality of flow path bodies including first axial ends and second axial ends that are positioned further from the fan than the first axial ends;
a mount provided in the housing between fan and the separator and including:
a mounting body having a top face and a mounting space defined therein;
a plurality of openings in a bottom face of the mounting body and positioned to correspond to the first axial ends of the flow path bodies, the plurality of openings including at least one first opening in a first region of the bottom face and at least one second opening in a second region of the bottom face;
and
a filter positioned in the mount to filter air flowing to the fan and including:
a 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.
