Separation Assembly For a Vaccuum Cleaner With Multi-Stage Dirt Separation
First Claim
1. A separation assembly for separating at least solid particles from air in a vacuum cleaner, comprising:
- an air inlet;
an air outlet;
wall sections bounding an air flow path from the inlet to the outlet; and
at least two separators for separating at least solid particles from the air,wherein the air flow path extends through said separators, an upstream one of said separators being located upstream of a downstream one of said separators, and wherein the downstream separator includes an air-permeable filter element bounding an inner space, characterized in that;
the wall sections bounding the air flow path in the area of the downstream separator include at least a transparent section through which the filter element is visible; and
said inner space is located upstream of an area outside the filter element for filtering air flowing from inside the filter element to outside the filter element.

Abstract
The invention relates to a separation assembly for separating dirt and dust from air in a vacuum cleaner (1), through which assembly an air flow path extends from an inlet (5) to an outlet (6). The air flow path extends through an upstream separator (18) and a downstream separator (19). The downstream separator (19) includes an air-permeable filter element (28) bounding an inner space (27). The wall sections bounding the air flow path in the area of the downstream separator include at least a transparent section (30) through which the filter element (28) is visible. The inner space (27) is located upstream of an area (31) outside the filter element (28) for filtering air flowing from inside the filter element (28) to outside the filter element (28).
