Abstract

A cyclonic separator/collector device for a suction cleaner, comprising a housing and at least one cyclonic separator disposed within the housing, the or each cyclonic separator having a cyclone body with a circumferential wall of which at least a major part is spaced from the housing; the space between the housing and wall of the cyclone body(s) receiving separated dust from the cyclonic separator(s); wherein the space between the cyclone body and the housing includes a sound-insulating material. The arrangement provides sound insulation for the cyclonic separators.

Claims

1. A cyclonic separator/collector device for a suction cleaner, comprising a housing and a first cyclonic separator disposed within the housing, the first cyclonic separator having a cyclone body with a circumferential wall that is positioned within the housing to form a space between the circumferential wall and the housing, the space receiving separated dust from the first cyclonic separator during operation of the suction cleaner;

wherein the space between the cyclone body and the housing includes a sound-insulating material.

2. A separator/collector device according to claim 1 comprising a second cyclonic separator disposed within the housing, connected in parallel with the first cyclonic separator.

3. A separator/collector device according to claim 2 wherein the first and the second cyclonic separators are each disposed in a generally horizontal orientation within the housing.

4. A separator/collector device according to claim 3 wherein the housing includes a collection portion positioned below the first cyclonic separator and the second cyclonic separator wherein dust separated by the first and second cyclonic separators collects in the collection portion.

5. A separator/collector device according to claim 4 wherein the housing further comprises an end wall that includes an exit passage from the first and the second cyclone separators, and a pivotable door with a closed position wherein the dust collected within the housing part is retained within the housing, and an open position wherein the dust collected within the housing can be removed from the housing.

6. A separator/collector device according to claim 1 wherein the space between the first cyclone body and the housing provides a path for air flow through the cyclonic separator.

7. A separator/collector device according to claim 1, wherein the device is removeably mounted in relation to a body part of the suction cleaner.

8. A separator/collector according to claim 7 wherein a part of the housing forms part of an exterior surface of the suction cleaner.
