Claims19
A dust collecting unit of a vacuum cleaner, comprising:
- a collection body having a plurality of foreign object filtering chambers for filtering foreign objects and a plurality of foreign object storing chambers for storing foreign objects filtered from the foreign object filtering chambers;
- a sealing member for closing a lower portion of the collection body;
- and
- a separation plate formed horizontally at the collection body and having an exhaust member disposed at an upper side of the collection body, the exhaust member guiding airflow;
- wherein the plurality of foreign object filtering chambers comprises:
- a first foreign object filtering chamber disposed in an inner space of an inner wall extending to a downward direction of the separation plate;
- and
- at least one second foreign object filtering chamber provided at an outer side of the first foreign object filtering chamber;
- and
- wherein the plurality of foreign object storing chambers comprises:
- a second storing chamber defined as a space between the inner wall and an intermediate wall spaced at an outside of the inner walk;
- and
- a first storing chamber defined as an inner space of an outer wall spaced at an outside from the intermediate wall;
- and
- wherein the first and second foreign object filtering chambers and the first and second foreign object storing chambers are formed as one body.
