Abstract

Provided is a self-propelled vacuum cleaner comprising: a housing that has a inlet formed on a lower surface and an exhaust port formed at one of left and right sides at a rear part and that can be self-propelled; and a dust-catching part provided between the inlet and the exhaust port through a ventilation path, wherein

the dust-catching part includes a dust box disposed at the side of the inlet and an electrically powered fan disposed at the side of the exhaust port, the dust box and the electrically powered fan being configured to be separable.

Claims

1. :

A self-propelled vacuum cleaner comprising;

a self-propellable housing having a inlet disposed on a lower surface and an exhaust port disposed at one of left and right sides at a rear part; and

a dust-catching part disposed between the inlet and the exhaust port through a ventilation path, wherein

the dust-catching part includes a dust box disposed at the inlet side and an electrically powered fan disposed at the exhaust-port side, and

the dust box and the electrically powered fan being configured so as to be separable.

2. :

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

the electrically powered fan is disposed in the housing, and the dust box is detachably mounted to the rear part of the housing in the dust-catching part.

3. :

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

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

the electrically powered fan is disposed in the downstream ventilation path,

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-catching chamber provided between the inflow opening and the filter, and

the filter is supported in the dust box in a tilting manner such that an end of the filter at the discharge-opening side becomes lower than the discharge opening and the end opposite to the discharge opening becomes higher than the discharge opening.

4. :

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

the housing has a tilt side surface tilting in the horizontal direction toward a front side at the portion where the second packing is provided, and

the dust box has an opposite tilt side surface tilting in the horizontal direction 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.
