To improve reliability of the product, the storing chambers and the filtering chambers are integrally formed as one body.
Claims20
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 foreign object storing chamber for storing foreign objects filtered from the foreign object filtering chambers;
- a sealing member for closing a lower portion of the collection body;
- 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;
- a first foreign object filtering chamber disposed in an inner space of an inner wall extending to a downward direction of the separation plate;
- a second storing chamber defined as a space between the inner wall and an intermediate wall spaced at an outside of the inner wall;
- a first storing chamber defined as an inner space of an outer wall spaced at an outside from the intermediate wall;
- and
- a second foreign object filtering chamber extending vertically from the separation plate and having a lower end received in an inside of the second storing chamber, the storing chamber and the filtering chamber being formed as one body.
