Description

[Detailed Description of the Invention] This invention incorporates a cyclone into a filter type vacuum cleaner and puts it into practical use.

Conventional commercial vacuum cleaners mainly use the filter method, but 1
This method has the disadvantage that when cleaning items containing a large amount of fine powder, it immediately becomes cluttered, and an improvement in this problem has been desired.

The cyclone method is excellent, but applying it to a vacuum cleaner would make the device complicated and large, and it would be difficult to separate cotton, thin polyethylene paper, etc., and it would get caught in the cyclone path. Due to various problems, it was not put into full-scale practical use. The present invention has been put into practical use by eliminating these drawbacks, and an embodiment implemented as a commercial vacuum cleaner will be described below with reference to the drawings.

The cyclone used is cylindrical, and the top of the cylinder has a
'A-'yd Attach the entrance of the rotating spiral ticket /, 2 to the object. The upper part is fixed to the center of the disk B placed on the outer cylinder 3, and the outlet pipe 7 is fixed to the upper center of the first disk B. Inside the cyclone / there is a small horizontal disc / 3
For installation, the bottom of the cyclone is open.

The outer cylinder 3 is stepped at the bottom to increase its diameter, and a left tangential entry type hose connection pipe is attached to the outer periphery of this part. The mesh can be placed on the stepped part at the top.

A filter chamber 9 is placed on the top of the outer cylinder 3, and a filter 10 can be mounted on the ceiling. Furthermore, a blower for the suction bow 1 is attached to the upper part. Next, to describe the function of each part, dust and dirt sucked together with air from the tangential entry type hose connection pipe S are cleaned and rotated on the inner periphery of the outer cylinder 3, and coarse dirt is collected into the dust collection container. falls to g.

The reason why the outer cylinder 3 is stepped and widened is to assist this effect. Next, the air and dust rotate outside 1@
It ascends between 3 and cyclone/, but before that, paper polyethylene pieces and the like are thrown away by the net q attached to the stepped part.

Next, enter the inside of the cyclone through the whirlpool entrance. When entering the inlet, the rotational movement is accelerated and due to centrifugal force, the fine powder overflows the inner wall of the cyclone, passes between the horizontal disk, passes through the gap in the mesh, and falls into the dust collection container. do. The horizontal disc is used to prevent the dust that has entered the dust collection container g from rising up, and also to prevent the air sucked in from the hose connection port S from entering the lower part of the cyclone and going directly to the outlet pipe 7. It is something that cannot be passed through.

The air from which the fine powder has been separated enters the filter chamber 9 through the outlet pipe 7. Although the separation effect of the cyclone is excellent, it is still
Since it is not 00%, it is necessary to collect the remaining part with the filter 10.

However, since frequent filter replacement is not required, there is almost no need to worry about removing the filter.
The clean air that has passed through the filter passes through a suction blower and is discharged to the outside.

As explained above, this invention has succeeded in incorporating the cyclone method, which has not been put into practical use in conventional vacuum cleaners, into a simple, compact, and high-performance vacuum cleaner.

I think this will have a tremendous effect on dust treatment at each factory workplace where X-fine powder is generated.
