Abstract

The present disclosure relates to a dust collecting apparatus. The dust collecting apparatus includes a cyclone body forming a cyclone chamber; a plurality of inlets formed at the cyclone body, and causing air to enter through; and a discharging port formed at the cyclone body, and discharging the air from the cyclone chamber, wherein each inlet of the plurality of inlets is formed at a different height at a side of the cyclone body so that the air is divided to enter the cyclone chamber at a different height.

Claims

1. A dust collecting apparatus comprising:

a cyclone body forming a cyclone chamber;

a plurality of inlets formed at the cyclone body, the plurality of inlets allowing air to enter the cyclone chamber; and

a discharging port formed at the cyclone body, the discharging port allowing the air to discharge from the cyclone chamber,

wherein each inlet of the plurality of inlets is formed at a different height at a side of the cyclone body so that the air is divided to enter the cyclone chamber at different heights, and

wherein the plurality of inlets have a sectional area decreasing from a top inlet to a bottom inlet.

2. The dust collecting apparatus of claim 1, wherein the plurality of inlets is formed at a side of a top part of the cyclone body.

3. The dust collecting apparatus of claim 2, wherein each inlet of the plurality of inlets comprises a bottom end and a top end, wherein the bottom end of one inlet does not to overlap with the top end of a next inlet, respectively.

4. The dust collecting apparatus of claim 2, wherein the plurality of inlets comprises two inlets formed at the side of the cyclone body in angular intervals of 180 degrees.

5. The dust collecting apparatus of claim 1, further comprising:

an outer housing wrapping around the cyclone body, the outer housing having an housing inlet,

wherein the air entering through the housing inlet firstly is separated from dust in an inner space of the outer housing, and then, enters the cyclone chamber through the plurality of inlets so as to be secondly separated from dust in the cyclone chamber.

6. The dust collecting apparatus of claim 5, wherein the housing inlet is formed at a side of a top part of the outer housing,

wherein each inlet of the plurality of inlets is formed at an opposite side of a top part of the cyclone body and do not to overlap with each other.

7. A dust collecting apparatus comprising:

a cyclone body forming a cyclone chamber;

a first inlet formed at a first side of the cyclone body, the first inlet allowing air to enter the cyclone chamber at a first height;

a second inlets formed at a second side of the cyclone body, the second inlet allowing air to enter the cyclone chamber at a second height; and

a discharging port formed at the cyclone body, the discharging port allowing the air to discharge from the cyclone chamber, the first height being different than the second height,

wherein the first inlet has a first sectional area and the second inlet has a second sectional area, and

wherein the first and second sectional areas are different from one another.

8. The dust collecting apparatus of claim 7, wherein the first inlet is a top inlet and the second inlet is a bottom inlet, and wherein the first sectional area is larger than the second sectional area.

9. The dust collecting apparatus of claim 7, wherein the first inlet has a bottom end and the second inlet has a top end, and wherein the bottom end does not to overlap with the top end.

10. The dust collecting apparatus of claim 7, further comprising an outer housing wrapping around the cyclone body, the outer housing having an housing inlet, wherein the air entering through the housing inlet firstly is separated from dust in an inner space of the outer housing, and then, enters the cyclone chamber through the first and second inlets so as to be secondly separated from dust in the cyclone chamber.
