Suction device for a vacuum cleaner
First Claim
1. A suction device of a vacuum cleaner, comprising:
- a suction device body having an upper casing member and a lower casing member disposed oppositely to, and coupled with, the upper casing member;
a rotary brush chamber having a suction port formed therein; and
a turbine chamber partitioned off from the rotary brush chamber by a partition and interconnected with the rotary brush chamber through a passage formed in the partition;
a rotary brush rotatably supported in the rotary brush chamber;
a turbine rotatably supported in the turbine chamber and rotated by an air current drawn into the vacuum cleaner, the turbine driving the rotary brush;
a portion defining a service hole formed in the lower casing member of the suction device body, for partially exposing the turbine, the service hole being interconnected with an air passage;
a service hole cover having a pair of passage walls, defining a narrow air passageway, said service hole cover being removably mounted on the service hole;
and locking means for removably supporting the service hole cover.

Abstract
A vacuum cleaner suction device includes an upper casing member and a lower casing member that oppose each other. A rotary brush chamber in the suction device has a suction port formed therein. A turbine chamber that is separated from the rotary brush chamber but interconnected thereto through a passage formed in the partition that separates the rotary brush from the turbine chamber. The rotary brush is supported in the rotary brush chamber as is the turbine for driving the rotary brush. The turbine is rotated by an air current drawn into the vacuum cleaner. A service hole is formed on the turbine chamber of the seduction device body for partially exposing the turbine. The service hole is provided on a removable service hole cover with a locking portion for removably supporting the service hole cover. Contaminants that clog the passage to the tubing can be easily removed by opening the service hole by removing the service hole cover. Accordingly, there is no need to separate the upper and lower casing members of the suction device body. Vacuum cleaner maintenance and repair is made easier.
