Abstract

A cyclone dust collecting apparatus comprises at least one second cyclone unit having a first cyclone unit, an air passage for guiding air discharging via the first cyclone unit, and a discharge pipe wherein the discharge pipe comprises a passage guide member for guiding air discharged from the second cyclone unit. Because the passage guide member is mounted in the discharge pipe of the second cyclone part, a load of suction source reduces to decrease power consumption for operation of a cyclone dust collecting apparatus.

Claims

1. A cyclone dust collecting apparatus comprising:

a first cyclone unit, and

at least one second cyclone unit having an air passage for guiding air discharged via the first cyclone unit into the at least one second cyclone unit and a discharge pipe, wherein the discharge pipe comprises a passage guide member for guiding air discharged from the second cyclone unit, wherein the passage guide member comprises a plurality of guide ribs formed in an inner circumference of the discharge pipe, wherein the guide ribs are protruded from the inner circumference of the discharge pipe in a direction toward a center of the discharge pipe, wherein the guide ribs leave an air passage in the center of the discharge pipe, wherein the guide ribs are spaced apart from an inlet end of the discharge pipe in a direction of air movement, wherein the guide ribs comprise a bent part and a linear part, wherein the bent part is disposed at an inlet end of the discharge pipe, wherein the linear part is disposed at an outlet end of the discharge pipe, wherein the bent part and the linear part are integrally formed with each other, wherein the bent part comprises a round part to prevent contaminants in air from blocking the discharge pipe, and wherein the bent part is twisted.

2. A cyclone dust collecting apparatus comprising:

a cyclone body unit having a first cyclone and a plurality of second cyclone bodies disposed along the first cyclone;

an inlet and outlet unit engaged with an upper portion of the cyclone body unit, and having an air passage and a discharge pipe of the second cyclone unit;

a cover collecting air discharged from the plurality of second cyclone bodies to guide the air to a cleaner body;

a sealing member disposed between the cyclone body unit and the inlet and outlet unit; and

a dust collecting receptacle engaged with a lower portion of the cyclone body unit for collecting contaminants, wherein the discharge pipe comprises at least one guide rib protruded from an inner circumference toward a center of the discharge pipe, wherein the guide ribs are spaced at a certain interval along the inner circumference of the discharge pipe, and wherein the guide ribs comprise a linear part and a bent part, and the bent part is twisted.

3. The apparatus according to claim 2, wherein the guide ribs are protruded from the inner circumference of the discharge pipe as high as 5 percent to 45 percent of a inside diameter of the discharge pipe.

4. A cyclone dust collecting apparatus comprising:

a plurality of second cyclone units each having an air inlet passage and a discharge pipe, the discharge pipe having a passage guide member for guiding air discharged from each of the plurality of second cyclone units, the passage guide member including a plurality of guide ribs formed in an inner circumference of the discharge pipe, the plurality of guide ribs protruding from the inner circumference in a direction toward a center of the discharge pipe, the plurality of guide ribs have a twisted configuration, wherein the plurality of guide ribs are spaced apart from an inlet end of the discharge pine in a direction of air movement.

5. The apparatus according to claim 4, further comprising a first cyclone unit, the air inlet passage guiding air discharged from the first cyclone unit into the plurality of second cyclone units.

6. The apparatus according to claim 4, wherein the guide ribs comprise a bent part and a linear part.

7. The apparatus according to claim 6, wherein the bent part is disposed at the inlet end of the discharge pipe and the linear part is disposed at an outlet end of the discharge pipe.

8. The apparatus according to claim 7, wherein the bent part comprises a round part to prevent contaminants in air from blocking the discharge pipe.
