Abstract

A vacuum cleaner is provided comprising a housing (1) with two filter systems (2,3) arranged in series, means (4) for generating an air flow through the filter systems, the second filter system (3) as seen in the direction of flow being a cyclone filter system, which vacuum cleaner is provided with one reservoir (5) for collecting dust from both filter systems (2,3), which reservoir can be closed off with a lid (14), is suitable for accommodating a disposable dust bag (6), and is furthermore divided into two compartments (5a, 5b) by a wall (13), each reservoir compartment serving to collect separated dust from the accompanying filter system, while the wall (13) is fastened in the reservoir (5) in such a way that it can be taken out. Preferably, the removable wall (13) is fastened to the lid (14).

As a result, the user can remove all the dust from the vacuum cleaner in one operation.

Claims

1. A vacuum cleaner comprising a housing (1) with two filter systems (2, 3) connected in series and means for generating an air flow through the filter systems, the second filter system (3) as seen in the direction of flow being a cyclone filter system, wherein the vacuum cleaner is provided with one reservoir (5) for collecting dust from both filter systems (2, 3), which reservoir can be closed off by a lid (14), is suitable for accommodating a disposable dust bag (6), and is furthermore divided into two compartments (5a, 5b) by a wall (13), each reservoir compartment serving to collect dust separated by the accompanying filter system, while the said wall (13) is fastened in the reservoir (5) in such a way that it can be removed.

2. A vacuum cleaner as claimed in claim 1 wherein the removable wall (13) is fastened to the lid (14).

3. A vacuum cleaner as claimed in claim 2 wherein the cyclone filter system (3) is fastened to the lid (14).

4. A vacuum cleaner as claimed in claim 3 wherein the lid (14) is hinged to the housing (1) of the vacuum cleaner.

5. A vacuum cleaner as claimed in claim 1 wherein a window frame (8) is present for clamping an edge of the disposable dust bag (6) on an upper rim (7) of the reservoir (5).

6. A vacuum cleaner as claimed in claim 1 wherein the first filter system (2) as seen in the direction of flow is formed by a plate (9) provided with holes.

7. A vacuum cleaner as claimed in claim 6 wherein the holes said are not more than 2 mm large.

8. A vacuum cleaner as claimed in claim 6 wherein the lid (14) is provided with an inlet opening (15) for the first filter system (2).

9. A vacuum cleaner as claimed in claim 1, wherein the first filter system (2) as seen in the direction of flow is also a cyclone filter system and in that both cyclone filter systems (2, 3) are arranged next to one another.

10. A vacuum cleaner as claimed in claim 9 wherein both cyclone filter systems (2, 3) are fastened to the lid (14) and are each provided with a flat, box-shaped cyclone chamber (20, 10) whose bottom comprises a discharge slot (21, 11) which provides access to the accompanying reservoir (5a, 5b).
