Upright vacuum cleaner
First Claim
1. A vacuum cleaner comprising:
- a cleaner body;
a multi cyclonic chamber being in fluid communication with the cleaner body, the multi cyclonic chamber comprising, a primary cyclone having a primary airflow inlet and a primary airflow outlet for separating contaminants from an airflow, and at least one secondary cyclone for separating contaminants entrained in the airflow discharged from the primary cyclone;
a suction source having a suction source inlet and a suction source outlet, the suction source operative to generate and maintain the airflow flowing from the suction source inlet to the suction source outlet, the suction source being located in the cleaner body below the multi cyclonic chamber; and
a main filter assembly including a main filter element comprising a selectively permeable material, the main filter assembly located in the cleaner body for filtering contaminants from the airflow that passes through the cyclonic chamber;
a discharge member having an opened upper end and a closed lower end, the opened upper end is coupled separably to the peripheral edge of the primary airflow outlet; and
a guide rib provided at the primary cyclone for guiding the airflow in a direction tangential to the inner peripheral wall surface of the primary cyclone.

Abstract
A vacuum cleaner is disclosed. The vacuum cleaner comprises a cleaner body, a multi cyclonic a primary cyclone and at least one secondary cyclone, a suction source having a suction source inlet and a suction source outlet, a main filter assembly including a main filter element comprising a selectively permeable material, a discharge member having an opened upper end coupled to the peripheral edge of the primary airflow outlet and a closed lower end, and a guide rib provided at the primary cyclone for guiding the airflow in a direction tangential to the inner peripheral wall surface of the primary cyclone. Accordingly, it is possible to separate easily and conveniently dust and dirt from the airflow and deposit the dust and dirt into the dust collecting container.
