Abstract

A self-propelled vacuum cleaner comprising: a self-propellable case having a suction opening provided on a bottom surface and an exhaust opening provided at a rear part; and a dust-collecting part provided between the suction opening and the exhaust opening through a ventilation channel, wherein

• • the dust-collecting part includes a dust box disposed at the suction-opening side and an electric fan disposed at the exhaust-opening side, and
  • the dust box and the electric fan are configured to be separable.

Claims

1. A self-propelled vacuum cleaner comprising:

a self-propellable case having a suction opening provided on a bottom surface and an exhaust opening provided at a rear part; and

a dust-collecting part provided between the suction opening and the exhaust opening through a ventilation channel, wherein

the dust-collecting part includes a dust box disposed at the suction-opening side and an electric fan disposed at the exhaust-opening side, and

the dust box and the electric fan are configured to be separable.

2. The self-propelled vacuum cleaner according to claim 1, wherein

the electric fan is disposed in the case, and the dust box is detachably mounted to the rear part of the case in the dust collecting part.

3. The self-propelled vacuum cleaner according to claim 2, wherein

the case includes a rear opening into which the dust box is fitted, an upstream ventilation channel that allows the suction opening and the rear opening to communicate with each other, a downstream ventilation channel that allows the exhaust opening and the rear opening to communicate with each other, a first packing provided around a first connection opening of the upstream ventilation channel at the rear-opening side, and a second packing provided around a second connection opening of the downstream ventilation channel at the rear-opening side,

the electric fan is disposed in the downstream ventilation channel, and

the dust box includes an inflow opening connectable to the first connection opening through the first packing, a discharge opening connectable to the second connection opening through the second packing, a filter provided between the inflow opening and the discharge opening, and a dust collecting chamber provided between the inflow opening and the filter.

4. The self-propelled vacuum cleaner according to claim 3, wherein

the case has a tilt lower surface tilting downward toward a front side at the portion where the second packing is provided, and

the dust box has a tilt upper surface tilting downward toward a front side at the portion where the discharge opening is formed.

5. The self-propelled vacuum cleaner according to claim 3, wherein

the dust box has a dust fall prevention member provided at the inflow opening for preventing dust in the dust box from leaking and falling from the inflow opening.
