Abstract

A vacuum cleaner comprises a collection chamber located along an intended path through which air current and detritus is conveyed, said collection chamber being provided with a collection zone in which said detritus is receivable, wherein said collection chamber is provided with a compacting device movable across said collection zone for compacting said detritus.

Claims

1. Vacuum cleaner comprising:

a collection chamber located along an intended path through which air current and detritus is conveyed, said collection chamber being provided with a collection zone in which said detritus is receivable,

wherein said collection chamber is provided with a compacting device movable across said collection zone for compacting said detritus, said collection chamber including a boxed tank slidably received in a receiving seat provided within the vacuum cleaner,

wherein, along said intended path, a filter chamber arrangement is provided housing a filter arrangement for filtering said air current, and

wherein said filter chamber arrangement comprises a first filter chamber adjacent to said collection chamber and communicating with said collection chamber through an opening arrangement of a barrier.

2. Vacuum cleaner according to claim 1, wherein said filter chamber arrangement comprises a second filter chamber adjacent to said first filter chamber, and communicating with said first filter chamber through an aperture of a common wall.

3. Vacuum cleaner according to claim 2, wherein said filter chamber arrangement comprises an exit chamber adjacent to said second filter chamber, and communicating with said second filter chamber through a housing of a sucking unit.

4. Vacuum cleaner comprising:

a collection chamber located along an intended path through which air current and detritus is conveyed, said collection chamber being provided with a collection zone in which said detritus is receivable,

wherein said collection chamber is provided with a compacting device movable across said collection zone for compacting said detritus, said collection chamber including a boxed tank slidably received in a receiving seat within the vacuum cleaner,

wherein said compacting device comprises a pusher unit having a buffer so driven as to compact said detritus in said boxed tank, and

wherein said boxed tank is rotatably received in said seat so that said boxed tank can be rotated between an extracting position, in which a loading opening faces upwards, and a loading position in which said loading opening faces said pusher unit.

5. Vacuum cleaner comprising:

a collection chamber located along an intended path through which air current and detritus is conveyed, said collection chamber being provided with a collection zone in which said detritus is receivable,

wherein said collection chamber is provided with a compacting device movable across said collection zone for compacting said detritus, said collection chamber including a boxed tank slidably received in a receiving seat within the vacuum cleaner,

wherein said compacting device comprises a pusher unit having a buffer so driven as to compact said detritus in said boxed tank, and

wherein said buffer is so shaped as to shapingly fit with a slit of said seat.

6. Vacuum cleaner comprising:

a collection chamber located along an intended path through which air current and detritus is conveyed, said collection chamber being provided with a collection zone in which said detritus is receivable,

wherein said collection chamber is provided with a compacting device movable across said collection zone for compacting said detritus, said collection chamber including a boxed tank slidably received in a receiving seat within the vacuum cleaner, and

wherein said seat has a substantially cylindrical shape for snugly accommodating said boxed tank.

7. Vacuum cleaner according to claim 6, wherein said boxed tank and said seat have a common longitudinal axis.

8. Vacuum cleaner according to claim 7, wherein said common longitudinal axis is transversely disposed of a longitudinal axis of said buffer.

9. Vacuum cleaner, comprising a collection chamber located along an intended path through which air current and detritus is conveyed, said collection chamber being provided with a collection zone in which said detritus is receivable,

wherein said collection chamber is provided with a barrier positioned transversally of a flow direction of said air current and detritus,

wherein along said intended path, a filter chamber arrangement is provided housing a filter arrangement for filtering said air current, and

wherein said filter chamber arrangement comprises a first filter chamber adjacent to said collection chamber and communicating with said collection chamber through an opening arrangement of said barrier.

10. Vacuum cleaner according to claim 9, wherein said filter chamber arrangement is releasably fitted to an enclosure arrangement.

11. Vacuum cleaner according to claim 9, wherein said filter chamber arrangement comprises a second filter chamber adjacent to said first filter chamber, and communicating with said first filter chamber through an aperture of a common wall.

12. Vacuum cleaner according to claim 11, wherein said filter chamber arrangement comprises an exit chamber adjacent to said second filter chamber, and communicating with said second filter chamber through a housing of a sucking unit.
