  • An inlet aperture 106 opened so that waste flows into the dust container 100 is provided at a front-lower part of the dust container 100.
  • the dust container 100 is provided with a hook insertion recess 110, which is formed to have a concave recess toward an inside direction thereof, in one side thereof. Further, the dust container 100 is provided with a hinge 120 protruding in a vertical direction thereof in an opposite side thereof.
  • the hook insertion recess 110 and the hinge 120 are provided so as to attach/detach the dust collection blade 200 to/from the dust container 100, and will be described below in detail together with the dust collection blade 200.
  • the dust container 100 includes a leaking prevention plate 124 protruding from a lower surface thereof in a predetermined height so as to block a lower part of the inlet aperture 106.
  • the leaking prevention plate 124 serves to prevent waste, such as dust, collected closely to the inlet aperture 106 from being arbitrarily spilled when the dust collection blade 200 is separated from the dust container 100.
  • the height of the leaking prevention plate 124 is formed to be smaller than that of the dust collection blade 200 so that waste may smoothly flow into the dust container 100.
  • the dust collection blade 200 is installed in front of the inlet aperture 106.
  • the dust collection blade 200 serves to guide waste carried in the rear direction by rotation of the brush 2 to flow into the dust container 100.
  • FIG. 4 is a side view of the dust collection blade according to an exemplary embodiment of the present invention
  • FIG. 5 is a view illustrating a modified state of the dust collection blade.
  • the dust collection blade 200 includes a plurality of supporting protrusions 202 elongated in a lengthwise direction, that is, a lateral direction, of the dust collection blade 200 on a rear surface thereof.
  • the lower end part of the dust collection blade 200 When a lower end part of the dust collection blade 200 is in contact with a protruding floor or an obstacle on the floor during the cleaning by the cleaning robot 1, the lower end part of the dust collection blade 200 needs to be bent so as not to disturb driving of the cleaning robot 1 to pass the obstacle, and the like.
  • the dust collection blade 200 needs to be formed so as to pass an obstacle while being bent in the opposite direction of a driving direction even though the dust collection blade 200 is in contact with the obstacle, such as the door sill protruding from a floor or a carpet, as illustrated in FIG. 5 .
  • a shape of the dust collection blade 200 may be restored at a beginning time by elasticity of the dust collection blade 200 itself, but when the bending is repeated, the dust collection blade 200 loses elasticity and is permanently deformed.
  • the supporting protrusion 202 serves to improve restoration force of the dust collection blade 200 and prevent permanent deformation thereof to continue high cleaning efficiency for a long time.
  • the plurality of supporting protrusions 202 is preferably formed to have a smaller diameter as the plurality of supporting protrusions 202 is disposed closer to the lower end of the dust collection blade 200 so that the dust collection blade 200 may be bent more smoothly.
