Abstract

The invention relates to a vacuum cleaner comprising a housing (1) accommodating a suction unit (7). The vacuum cleaner further comprises a dust container (11) in which a dust filter (21) can be placed. The dust container is detachably coupled to the housing and comprises a handle (33) and an opening (31) via which the dust filter can be placed. According to the invention, the handle is provided on a side wall (39) of the dust container, while the opening is provided at an upper side (35) of the dust container, the upper side of the dust container being directed towards an upper side (37) of the housing in an operational position of the vacuum cleaner. In this manner, it is prevented that the dust filter can fall out of the dust container or that dust can fall out of the dust filter when the dust container is detached from the housing. In a preferred embodiment, the handle of the dust container also is a unique handle for the housing, so that the construction of the housing is simplified. In a further embodiment, the dust container is coupled to the housing by means of a first coupling device (65), which is provided near a lower side (67) of the handle, and a second coupling device (69) which is provided near an upper side (71) of the handle. In this manner, a rigid coupling of the dust container to the housing is obtained.

Claims

1. A vacuum cleaner comprising a housing, which accommodates a suction unit, a cover pivotable to said housing and a dust container which is detachably coupled to said housing and in which dust container a dust filter is provided, said dust container provided with an opening for introducing the dust filter into said dust container and, on an outside, with a handle, characterized in that the handle is provided on a side wall of said dust container, and the opening is situated at an upper side of said dust container, the upper side of said dust container facing the cover when the vacuum cleaner is in an operating position.

2. A vacuum cleaner as claimed in claim 1, characterized in that the handle also forms a handle for the housing.

3. A vacuum cleaner as claimed in claim 1 wherein the opening is closable by the cover.

4. A vacuum cleaner as claimed in claim 3, characterized in that the dust container is coupled to the housing by means of a first coupling member, which is provided near a lower side of the handle to co-operate with the housing, and a second coupling member which is arranged near an upper side of the handle to co-operate with the cover.

5. A vacuum cleaner as claimed in claim 4, characterized in that the first coupling member has a cam for co-operating with a cam holder of the housing, which cam holder conforms to with said cam.

6. A vacuum cleaner as claimed in claim 4 wherein the second coupling member comprises a blocking member which can be displaced by means of an operating member from a first position, wherein the blocking member locks the cover in a closed position with respect to said dust container, to a second position wherein the blocking member releases the cover.

7. A vacuum cleaner as claimed in claim 6, characterized in that the operating member is arranged in an upper side of the handle.

8. A vacuum cleaner as claimed in claim 6, characterized in that the second coupling member includes a safety member which locks the blocking member in its first position if the housing is not in the operating position.

9. A vacuum cleaner as claimed in claim 3 wherein the cover is provided with a connection member suitable for coupling to a suction hose, said suction hose being adapted to connect a suction accessory to said dust container and the suction unit.
