BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vacuum cleaner, and more particularly, to a vacuum cyclone dust collector for centrifuging dust contained in an intake air, the first having a rectangular shape at a position close to a wall in a flow chamber for inducing air flow. By forming a cut-out hole and a second cut-out hole, and attaching a debris removal screen to the inside of the first cut-out hole and the second cut-out hole, it prevents the backflow of the foreign matter collected in the dust collecting chamber, and improves the air revolution speed. It is configured to improve dust collection efficiency by improving.

In general, the vacuum cleaner which cleans the floor or the gap by suctioning and collecting dust or dirt by the negative pressure according to the operation of the vacuum pump is generally connected to the suction pipe at the tip of the flexible hose connected to the main body. In addition, the brush has a structure in which a brush which directly sucks foreign matters by moving in close contact with the bottom surface of the suction pipe.

The vacuum cleaner typically includes an antibacterial dust bag inside the dust collecting chamber formed in the main body, thereby cleaning the foreign matter in the air sucked through the brush, the suction pipe and the flexible hose according to the negative pressure of the vacuum pump. While the bag is removed by filtration, only the pure air is discharged to the outside to clean the bottom.

The dust bag is composed of pulp, paper or nonwoven fabric, and is formed in a bag shape. On one side, a circular intake hole is formed so that air containing a foreign matter is introduced therein, and the foreign matter is filtered out of the portion except the intake hole. It consists of a structure in which a plurality of ventilation holes having a fine size is formed so that air is transmitted by the negative pressure according to the operation of the vacuum pump.

On the other hand, while the dust bag has a limited collection capacity, the intake hole is clogged by foreign matters and thus cannot be used repeatedly, so a conventional vacuum cleaner takes a large amount of dust bags in proportion to the amount of dust collected.

Therefore, a conventional vacuum cleaner requiring a dust bag has a problem such as a lot of additional costs in use.

In addition, the conventional vacuum cleaner using the dust bag, there is a problem such as a lot of trouble in the process of removing or mounting the dust bag through the dust chamber interior space.

Accordingly, the vacuum cleaner developed recently has introduced a cyclone dust collector which separates the foreign substances contained in the air by applying a centrifugal force to the air sucked with the foreign substances by the negative pressure of the vacuum pump, thereby eliminating any foreign substances such as dust bags. Capture.

On the other hand, as described above, as a cyclone dust collector for a vacuum cleaner using centrifugal force, a number of methods are known, including 2003 Patent Application No. 96558 filed by the present applicant.

This 2003 Patent Application No. 96558 contains foreign matters according to the negative pressure of the vacuum pump due to the characteristics of the air inlet and exhaust port and the shape of the flow chamber having the air guide in the lower portion of the air introduced from the outside together with the foreign matters. In the process of sucking air, the air is rotated at a high speed, and in this process, centrifugal force is generated in the air including the foreign matter.

Therefore, the foreign matter contained in the air is separated from the air by the specific gravity difference with the air is collected into the dust collecting chamber formed in the lower portion of the cyclone dust collector, and thus configured to remove the foreign matter.

The 2003 patent application No. 96558 is a flow formed in a circular shape in the process in which the air introduced with the foreign matter through the inlet port 130 is discharged to the exhaust port 140 acting the negative pressure of the vacuum pump as shown in FIG. The inner wall of the chamber 150 is rotated at high speed.

As described above, when the air containing the foreign matter is turned at high speed, the centrifugal force is generated in the air containing the foreign matter, and the dust and the like having a relatively higher specific gravity than the air are collected in the dust collecting chamber 160 in close contact with the wall surface by the centrifugal force. According to the above process, the air from which the foreign matter is first removed is discharged through the exhaust port 140 in a state in which the foreign matter is removed via the cyclone dust collecting filter 120.

In 2003 Patent Application No. 96558 having such a principle, dust removal can be performed smoothly without consumables such as dust bags, and in particular, dust collection is more efficient than conventional cyclone dust collectors.

In addition, by providing a fine dust removal filter to remove the fine dust in the cyclone dust collecting filter 120, the fine dust that is not removed by the centrifugal force is removed by the fine dust filter, it is excellent in the collection efficiency for fine dust Has many advantages.

However, the 2003 Patent Application No. 96558, as the air introduced into the dust collecting chamber 160 by the centrifugal force circulates inside the dust collecting chamber 160 to collect the foreign matter to the bottom of the dust collecting chamber 160, and then the dust collecting slot Part of the air circulated in the process of being discharged to the outside through the 160A collides with the bottom of the air guide 110 and the dust collecting chamber 160, so that a part of the dust collected inside the dust collecting chamber 160 is flow chamber 150 Problems such as backflow.

In addition, as shown in FIG. 2, the air inlet part 110A formed at one side of the air guide 110 is formed in the entire upper part of the dust collecting chamber 160 such that air flows into the dust collecting chamber 160. As a portion of the air turning in the inflow to the dust collecting chamber 160 through the air inlet (110A), the rotation speed of the air is lowered.

Therefore, the above-mentioned 2003 Patent Application No. 96558 does not maximize the dust collection efficiency, and a problem occurs such that some of the dust collected in the dust collecting chamber 160 is scattered.

The present invention is to solve the problem of a vacuum cleaner having a cyclone dust collector, including the 2003 patent application No. 96558, the first application by the present applicant, the technical problem of the present invention is contained in the intake air In the cyclone dust collector for vacuum cleaner which centrifuges the dust, the first and second incisions each having a rectangular shape are formed in a position close to the wall in the flow chamber that induces the flow of air, and the first incision is described above. By attaching a foreign matter removal screen inside the ball and the second incision hole, it is possible to provide a cyclone dust collector that can prevent the backflow of the foreign matter collected in the dust collecting chamber and improve the dust collecting efficiency by improving the rotation speed of air.
