Abstract

The present application relates to a cleaning appliance including: 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; an intake port communicating the first space with an exterior of the housing; an exhaust including a cover through-hole and an exhaust hole defined to pass through a top face of the housing; a fan fixed to the wall or the second space and positioned in the wall through-hole, wherein the fan flows air in the first space to the exhaust hole; a separator disposed in the first space to form a flow path for guiding air flowed into the intake port to the fan, wherein the separator separates a foreign matter from the air using a centrifugal force; and a display including: a display panel exposed to the exterior of the housing through the cover through-hole; a display housing fixing the display panel thereto; and a housing fastening portion for fixing the display housing to the wall or an inner circumferential face of the housing.

Dependent claims

A cleaning appliance comprising:

a hollow housing;
a housing wall provided in the housing to divide an internal space of the housing into a first space and a second space;
a wall through-hole provided in the housing wall;
an intake port, the first space communicating with an exterior of the housing via the intake port;
an exhaust provided in a housing through-hole provided in the housing such that the second space communicates with the exterior of the housing through the housing through-hole, the exhaust including:
a housing cover configured to be received in the housing through-hole;
a cover through-hole provided in the housing cover;
and
an exhaust hole provided the housing cover, the second space communicating with the exterior of the housing through the exhaust hole;
a fan including:
a casing configured to be coupled to at least one the housing wall or a surface facing the second space such that the casing is positioned in the wall through-hole;
a casing intake hole provided in the casing, the first space communicating with an interior of the casing through casing intake hole;
a casing exhaust hole provided in the casing;
and
an impeller to generate an air flow into the interior of the casing via the casing intake hole and out of the interior of the casing via the casing exhaust hole;
a separator provided in the first space to form a flow path for air from the intake port to the casing intake hole, wherein the separator separates matter from the air flow using centrifugal force;
and
a display including:
a display panel;
a display housing coupled to the display panel;
and
at least one housing fastening extension that is configured to couple the display housing to at least one of the housing wall or an inner circumferential surface of the housing such the display panel is positioned to be exposed to the exterior of the housing through the cover through-hole.
