Device for sucking up particles to be collected and a floor vacuum cleaner

1. A vacuum cleaner comprising:

at least one collection chamber for accumulating the particles;

a suction device;

at least one reception chamber storing said suction device;

a partition separating said collection chamber from said reception chamber and having a partition surface, said partition having an inlet orifice formed therein for channeling an air stream from said collection chamber to said suction device, said inlet orifice of said partition coupling said collection chamber to said suction device in said reception chamber;

an air guide funnel having an entry surface forming a part of said partition surface, the air guide funnel directly contacting the suction device;

an intervention guard element connected to the air guide funnel and projecting in a direction toward said collection chamber, wherein said intervention guard element is a dome-shaped rigid ribbed body having gaps formed therein for a largely unobstructed routing of the air stream from said collection space through to said suction device;

a filter bag disposed in said collection space for accumulating the particles.

2. The vacuum cleaner according to claim 1 , wherein said air guide funnel is provided, with respect to said entry surface, in said partition such that an approximately straight suction air stream is provided from said collection chamber to said suction device in said reception chamber.

3. The vacuum cleaner according to claim 1 , wherein said entry surface of said air guide funnel is a substantially rectangular entry surface on a same side as said collection chamber.

4. The vacuum cleaner according to claim 1 , wherein said air guide funnel narrows largely continuously in a direction of said suction device.

5. The vacuum cleaner according to claim 1 , wherein:

said suction device has a blower with an entry orifice formed therein; and

said air guide funnel has an exit surface having a substantially circular configuration and a diameter corresponding substantially to said entry orifice of said blower of said suction device.

6. The vacuum cleaner according to claim 1 , wherein said air guide funnel is integrated as an independent structural part into said partition.

7. The vacuum cleaner according to claim 1 , wherein said partition and said air guide funnel form a one-piece jointly produced structural part.

8. The vacuum cleaner according to claim 1 , further comprising at least one filter element for purifying the air stream from said collection chamber to said suction device, said filter element is disposed upstream of said entry surface of said air guide funnel.

9. A vacuum cleaner, comprising:

a collection chamber for accumulating particles;

a suction device including a motor and a blower generating an air flow;

a reception chamber housing the suction device;

a partition separating the collection chamber from the reception chamber and defining an inlet orifice receiving the air flow from the collection chamber;

an air guide funnel connected to the partition at the inlet orifice and extending away the collection chamber to an exit orifice, the air guide funnel directly contacting the suction device and being disposed adjacent the blower, the blower being disposed between the motor and the air guide funnel; and

an intervention guard element connected to the air guide funnel and projecting in a direction toward the collection chamber.

10. The vacuum cleaner according to claim 9 , wherein the air guide funnel and the partition are constructed together as a single integrally formed structural part.

11. The vacuum cleaner according to claim 9 , wherein the air guide funnel, the partition, and the intervention guard element are constructed together as a single integrally formed structural part formed from the same material.

12. The vacuum cleaner according to claim 9 , wherein the intervention guard element is a dome-shaped rigid ribbed body having gaps formed therein for a largely unobstructed routing of the air stream from the collection space through to the suction device.

13. The vacuum cleaner according to claim 9 , further comprising a filter bag disposed in the collection space for accumulating the particles.

14. The vacuum cleaner according to claim 9 , further comprising a filter element covering the inlet orifice and purifying the air flow from the collection chamber to the suction device.

15. A vacuum cleaner, comprising:

a collection chamber for accumulating particles;

a suction device including a motor and a blower generating an air flow;

a reception chamber housing the suction device;

a partition separating the collection chamber from the reception chamber and defining an inlet orifice receiving the air flow from the collection chamber;

an air guide funnel connected to the partition at the inlet orifice and extending away the collection chamber to an exit orifice disposed adjacent the blower, the blower being disposed between the motor and the air guide funnel;

an intervention guard element including a dome-shaped rigid ribbed body connected to the air guide funnel and projecting in a direction toward the collection chamber; and

a filter bag disposed in the collection space for accumulating the particles.

16. The vacuum cleaner according to claim 15 , wherein the air guide funnel and the partition are constructed together as a single integrally formed structural part.

17. The vacuum cleaner according to claim 15 , wherein the air guide funnel, the partition, and the intervention guard element are constructed together as a single integrally formed structural part formed from the same material.

18. The vacuum cleaner according to claim 15 , further comprising a filter element covering the inlet orifice and purifying the air flow from the collection chamber to the suction device.
