Abstract

A cyclonic separating apparatus for a vacuum cleaner that can separately collect dust and water. The cyclonic separating apparatus includes: a cyclone body having an air inlet passage and an air discharge passage; a dust receptacle connected to a lower end of the cyclone body; and a screen dividing the cyclone body and interior space of the dust receptacle into a first chamber and a second chamber, the screen having a plurality of passing holes, wherein drawn air rotates in the first chamber and water separated from the air moves to the second chamber through the passing holes.

Claims

1. A cyclonic separating apparatus, comprising:

a cyclone body having an air inlet passage and an air discharge passage;

a dust receptacle connected to a lower end of the cyclone body; and

a screen dividing the cyclone body and an interior space of the dust receptacle into a first chamber and a second chamber, the screen having a plurality of passing holes,

wherein drawn air rotates in the first chamber and water separated from the air moves to the second chamber through the passing holes.

2. The cyclonic separating apparatus of claim 1, wherein the screen is a cylindrical container, and the passing holes are inclined in the direction of rotation of the drawn air.

3. The cyclonic separating apparatus of claim 2, wherein the passing holes of the screen are formed between a junction of the cyclone body and the dust receptacle, and an inlet port of the air inlet passage.

4. The cyclonic separating apparatus of claim 1, wherein at least one of the passing holes forms an elliptical shape.

5. The cyclonic separating apparatus of claim 1, wherein the screen is surrounded by the cyclone body.

6. The cyclonic separating apparatus of claim 1, wherein the screen is separated into sections, wherein center lines of at least two passing holes disposed in the same section are parallel to each other.

7. The cyclonic separating apparatus of claim 1, wherein an upper most part of the screen is in a funnel shape with an increasing inner diameter in the upward direction.

8. The cyclonic separating apparatus of claim 1, wherein the screen comprises an upper part where the passing holes are formed, and a lower part where the passing holes are not formed.

9. The cyclonic separating apparatus of claim 8, further comprising at least one guide member to partition the second chamber of the dust receptacle so as to restrict rotation of the water once the water is separated into the second chamber.

10. The cyclonic separating apparatus of claim 9, wherein the screen has at least one opening at the lower part, and at least one backflow prevention member formed on the boundary of the opening.

11. The cyclonic separating apparatus of claim 8, further comprising three guide members equally spaced along an inside perimeter of the dust receptacle so as to restrict rotation of the water once the water is separated into the second chamber.

12. The cyclonic separating apparatus of claim 1, wherein the dust receptacle is at least partially formed of a transparent material.
