Abstract

A cyclonic separation device for a vacuum cleaner including a cylindrical housing, an inlet tube parallel to the axis of the housing having a vortex vane disposed axially in the inlet tube. Air rotates in one direction in the inlet tube, and preferably in the opposite direction in the housing. The housing includes a cylindrical sidewall with an upper central outlet tube and a closed bottom for collecting separated dirt. A disrupter ring located on the inside wall of the middle portion of the housing includes a curved surface and sharp edge for lifting air flow off the housing wall. An outlet tube disc spaced from the inlet of the outlet tube is located in the housing below the disrupter ring.

Claims

1. A cyclonic separation device for use with a vacuum source, comprising:

a cylindrical housing having a central axis, an inlet at the upper portion, an outlet at the top and a closed bottom forming an upper separation portion and a lower collection portion;

an inlet tube having an inlet opening and outlet opening positioned adjacent to the housing with an axis of the inlet tube substantially parallel to the central axis of the housing;

a vortex vane positioned in the inlet tube causing inlet air therein to circulate;

a transfer region at the upper portion of the housing, that is adjacent to the outlet opening of the inlet tube for introduction of circulating air into the housing;

a central outlet tube having an inlet in the housing and an outlet communicating with the vacuum source; and

the housing having a cylindrical sidewall with a disrupter ring located on the inside wall at a position below the inlet of the outlet tube.

2. The cyclonic separation device of claim 1, including an outlet tube disc positioned below the inlet to the outlet tube at a level below the disrupter ring.

3. The cyclonic separation device of claim 2, wherein the central outlet tube extending into the housing and the outlet tube disc is supported by ribs attached to the inlet of central outlet tube.

4. The cyclonic separation device of claim 2, wherein the outlet tube disc is supported in the middle region of the housing by a stem attached to the bottom of the housing.

5. The cyclonic separation device of claim 1, wherein the inlet tube has an openable cleanout cap at the outlet end of the inlet tube.

6. The cyclonic separation device of claim 1, wherein the vortex vane in the inlet tube progresses gradually from a first position at the inlet opening of the inlet tube to the outlet opening of the inlet tube where the guiding vane is between about 45°

to 75°

from the first position, after having completed a 360°

rotation within the inlet tube.

7. The cyclonic separation device of claim 6, wherein the guiding vane is about 60°

from the first position.

8. The cyclonic separation device of claim 2, wherein the outer diameter of the outlet tube disc extends to between about 40 to 75 percent of the diameter of the housing.

9. The cyclonic separation device of claim 1, wherein the bottom is selectively openable for removal of dirt collected on the bottom.

10. The cyclonic separation device of claim 1, wherein the selectively openable bottom has a side door that is hingedly connected to the housing for the removal of dirt collected on the bottom.

11. The cyclonic separation device of claim 1, wherein the disrupter ring extends inwardly into the housing between about 3 to 15 percent of the diameter of the housing.

12. The cyclonic separation device of claim 1, wherein the vortex vane rotates incoming air in a first direction and air fed into the housing in an opposite direction.

13. The cyclonic separation device of claim 1, wherein the vortex vane rotates incoming air in a first direction and air fed into the housing in the same direction.

14. A cyclonic separation device for use with a vacuum source, comprising:

a cylindrical housing having a central axis, an inlet at the upper portion, an outlet at the top and a selectively openable bottom forming an upper separation portion and a lower collection portion;

an inlet tube having an inlet opening and outlet opening positioned adjacent to the housing with an axis of the inlet tube substantially parallel to the central axis of the housing;

a vortex vane positioned in the inlet tube causing inlet air therein to circulate;

a transfer region at the upper portion of the housing, that is adjacent to the outlet opening of the inlet tube for introduction of circulating air into the housing;

a central outlet tube having an inlet in the housing and an outlet communicating with the vacuum source; and

the housing having a cylindrical sidewall with a disrupter ring located on the inside wall at a position below the inlet of the outlet tube.

15. The cyclonic separation device of claim 14, including an outlet tube disc positioned below the inlet to the outlet tube at a level below the disrupter ring.

16. The cyclonic separation device of claim 15, wherein the central outlet tube extending into the housing and the outlet tube disc is supported by ribs attached to the inlet of central outlet tube.

17. The cyclonic separation device of claim 15, wherein the outlet tube disc is supported in the middle region of the separation housing by a stem attached to the bottom of the housing.

18. The cyclonic separation device of claim 14, wherein the inlet tube has an openable cleanout cap at the outlet end of the inlet tube.

19. The cyclonic separation device of claim 14, wherein the vortex vane in the inlet tube progresses gradually from a first position at the inlet opening of the inlet tube to the outlet opening of the inlet tube where the guiding vane is between about 45°

to 75°

from the first position, after having completed a 360°

rotation within the inlet tube.

20. The cyclonic separation device of claim 19, wherein the guiding vane is about 60°

from the first position.

21. The cyclonic separation device of claim 15, wherein the outer diameter of the outlet tube disc extends to between about 40 to 75 percent of the diameter of the housing.

22. The cyclonic separation device of claim 14, wherein the selectively openable bottom has a side door that is hingedly connected to the housing for the removal of dirt collected on the bottom.

23. The cyclonic separation device of claim 14, wherein the disrupter ring extends inwardly into the housing between about 3 to 15 percent of the diameter of the housing.

25. The cyclonic separation device of claim 14, wherein the vortex vane rotates incoming air in a first direction and air fed into the housing in an opposite direction.

26. The cyclonic separation device of claim 14, wherein the vortex vane rotates incoming air in a first direction and air fed into the housing in the same direction.
