ABSTRACT:

TECHNICAL FIELD
The present invention relates to a central vacuum cleaning system, particularly to a central vacuum cleaning system having a filter carrier connected with a tube of a cleaning brush by an intake hose.
BACKGROUND ART
In general, a central vacuum cleaning system consists of a power generating part
200
, a dust collecting part
300
, pipes
400
, a linker
500
, connecting hose
600
, and a cleaning unit as shown in FIG.
8
.
The cleaning unit sucks air containing dust in a room, and the intaken dust flows toward the linker
500
through the connecting hose
600
. The linker is installed at a predetermined position (for example, a wall) at a place to be cleaned. The dust flowing toward the linker
500
goes through the pipes
400
toward the power generating part
200
and the dust collecting part
300
, wherein the power generating part
200
is integrally formed with the dust collecting part
300
. The power generating part
200
receives electric power and generates a suction force caused by the rotation of a motor (not shown), and the dust collecting part
300
having a filter filters the collected matters from the intake air containing dust.
In the central vacuum cleaning system, as the refuse intaken with the air containing dust in the cleaning unit
700
is sucked through the connecting hose
500
and pipes
400
and is filtered at the filter in the dust collecting part
300
, the central vacuum cleaning system has a problem. After prolonged, the collected matters accumulate at the curved portion of the pipes
400
, and thus the pipes become clogged.
As the dust collecting part
300
is integral with the power generating part
200
, the radius of the pipes
400
and the connecting hose
600
must be long for sucking the air containing dust.
Also, as the cleaning unit
700
is directly connected to the connecting hose
600
, during the cleaning the weight of the connecting hose
600
is a burden upon the user.
DISCLOSURE OF INVENTION
Therefore, it is a first object of the present invention, for the purpose of solving the above mentioned problems, to provide a central vacuum cleaning system.
A second object of the present invention is to provide a central vacuum cleaning system preventing the pipes from accumulating the collected matter.
A third object of the present invention is to provide a central vacuum cleaning system having the pipes and the connecting hose having a small radius.
A fourth object of the present invention is to provide a central vacuum cleaning system which allows easy cleaning by the user.
