Turbine brush
First Claim
1. A turbine brush for a vacuum cleaner comprising:
- a brush body including an upper casing and a lower casing, the lower casing having sidewalls and a suction slot through which air is drawn in from a surface being cleaned;
an agitator unit rotatably supported at the lower casing and having bristles at predetermined intervals;
a turbine unit rotatably supported adjacent the lower casing and being rotated by the air drawn into the vacuum cleaner by suction force; and
a power transfer unit connecting the agitator unit and the turbine unit so as to rotate the agitator unit in association with the turbine unit, wherein the suction slot of the lower casing has a plurality of ribs to prevent the surface being cleaned from being drawn in to the brush body by the suction force generated by the vacuum cleaner, and the bristles are positioned at the predetermined intervals between the ribs of the suction slot so that at least a part of the bristles is passes through the suction slot and comes into contact with the surface being cleaned, whereby the ribs inhibit any loose material of the surface being cleaned from being drawn into the turbine brush.

Abstract
A turbine brush for a vacuum cleaner comprises a brush body having an upper casing and a lower casing, and the lower casing having a suction slot through which air is drawn in from a surface being cleaned, an agitator unit having bristles at predetermined intervals, a turbine unit rotatably supported within the lower casing and being rotated by the air drawn into the turbine brush by suction force generated by the vacuum cleaner, and a power transfer unit to cause the agitator unit and the turbine unit to rotate in association with each other. When cleaning surfaces having loose material, such as a blanket or other fabric, the suction slot of the lower casing includes a plurality of ribs to inhibit the blanket or other fabric from being drawn into the brush body by the suction force generated by the vacuum cleaner. The bristles are in contact with the surface being cleaned by passing through apertures in the suction slot defined by the plural ribs. The turbine brush enables a user to conveniently clean surfaces having loose material by inhibiting the blanket or fabric from being caught by the turbine brush. Preferably, the upper casing comprises a transparent material.

9. A turbine brush for a vacuum cleaner comprising:
-
a brush body in fluid communication with the vacuum cleaner comprising a lower casing having a suction slot through which air is drawn into the brush body from a surface being cleaned, and an upper casing being made from a transparent material;
an agitator unit rotatably supported at the lower casing and having bristles at predetermined intervals;
a turbine unit rotatably supported at the lower casing and rotating by action of the air drawn into the brush body by the suction force generated by the vacuum cleaner, a power transfer unit connecting the agitator unit and the turbine unit so as to rotate the agitator unit in association with the turbine unit, and a discharging pipe connected to a rear portion of the brush body, wherein the suction slot of the lower casing has a plurality of ribs to prevent the surface being cleaned from being drawn into the brush body by the suction force generated by the vacuum cleaner, and the bristles are positioned at predetermined intervals between the ribs of the suction slot so that at least a part of the bristles passes through the suction slot and comes into contact with the surface being cleaned. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17, 19)
