Abstract

A suction device of a vacuum cleaner including a suction device body having an upper casing member and a lower casing member disposed oppositely thereto, 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 for driving the rotary brush rotatably supported in the turbine chamber and rotated by an air current drawn into the vacuum cleaner; a portion defining a service hole formed on the turbine chamber of the suction device body for partially exposing the turbine; a service hole cover removably mounted on the service hole; and a locking portion for removably supporting the service hole cover. When contaminants clog in between the passage and the turbine, the contaminants 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 the lower casing members of the suction device body, but the service hole cover alone is opened for removal of the contaminants. As a result, maintenance or repairing of the vacuum cleaner becomes easier.

Claims

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 for driving the rotary brush;

a portion defining a service hole formed on the turbine chamber of the suction device body, for partially exposing the turbine;

a service hole cover removably mounted on the service hole; and

locking means for removably supporting the service hole cover.

2. The suction device of claim 1, wherein the service hole is formed in the lower casing member of the suction device body, interconnecting with an air passage, and the service hole cover has a pair of passage walls defining a narrower air passage in the air passageway.

3. The suction device of claim 2, wherein the turbine chamber of the lower casing member has a pair of arc-shaped guide ribs that have a radius of curvature identical with the radius of curvature of the turbine and are formed on both sides of the turbine chamber, and the pair of passage walls have curved portions that are formed on the pair of passage walls and shaped and dimensioned to contact the pair of arc-shaped guide ribs.

4. The suction device of claim 1, wherein the locking means comprises:

a pair of resilient parts having locking protrusions formed on both sides of the service hole cover to be resiliently biased outwardly from the service hole; and

a pair of locking grooves formed in both sides of the service hole to correspond with the suction device body for receiving the locking protrusions.

5. The suction device of claim 4, wherein the resilient parts have press parts extended vertically from the ends of the resilient parts, and receiving grooves formed in corresponding opposed section the suction device body to receive the press parts, respectively.
