Robot cleaner with improved dust collector
First Claim
1. A robot cleaner comprising:
- a suction hole to suction dust;
a blower to generate a suction force to suction the dust;
dust collector to receive the dust through the suction hole; and
a rotating brush to sweep up and collect the dust into the dust collector,wherein the dust collector includes a collecting region to receive the dust swept up by the rotating brush, and a backflow preventing member movably coupled at an inlet opening of the collecting region between an open position and a closed position,wherein the backflow preventing member is pivotably rotatable in an air suction direction by the suction force of the blower to the open position to suction the dust into the dust collector and is adapted to return to the closed position to prevent the dust in the dust collector from being discharged through the suction hole upon stoppage of the blower,wherein the backflow preventing member includes one end hingedly coupled to upper portion of the inlet opening, and the other end configured as a free end, andwherein the backflow preventing member is kept in an inclined state with respect to a vertical direction in the closed position such that the other end is contacted with an inner surface of the collecting region and supported by the inner surface of the collecting region.

Abstract
A robot cleaner including a suction hole to suction dust, a blower to generate a suction force to suction the dust, a dust collector to receive the dust suctioned by said suction force through the suction hole, and a rotating brush to sweep up and collect the dust into the dust collector through the suction hole by a drive force of the rotating brush. The dust collector includes a backflow preventing member movable between an open position and a closed position. The backflow preventing member is pivotably rotatable in an air suction direction by the suction force of the blower to the open position and is adapted to return to the closed position to prevent the dust in the dust collector from being discharged through the suction hole upon stoppage of the blower.

4. A robot cleaner comprising:
-
a body having a suction hole; a rotating brush disposed at a lower side of the body to sweep up or scatter dust on a floor; a blower provided inside the body to generate suction force; a dust collector having a collecting region to receive dust being introduced through the suction hole; and a backflow preventing member disposed at an inlet opening of the dust collector to prevent the dust in the collecting region from back-flowing toward the suction hole, wherein the backflow preventing member, upon operating of the blower, maintains an open position to open the inlet opening of the dust collector by moving in an air suction direction by the suction force of the blower, and upon stopping of the blower, maintains a closed position to close the inlet opening of the dust collector, and when the backflow preventing member is in the closed position, the backflow preventing member is kept in an inclined state such that a lower end of the backflow preventing member is located while being biased in the air suction direction with respect to an upper end of the backflow preventing member. - View Dependent Claims (5, 6, 7, 8)
