It consists of a foreign material guide tube 56 for guiding the foreign matter flow in the air flowing into the inside and the discharge pipe 58 for guiding the air flowing in the body 52 to the outside.

In more detail, the body 52 has a cylindrical shape as shown, so that the contaminated air (air mixed with air and foreign matter) introduced into the inside through the inlet pipe 54 flows in a spiral motion. You will be guided. That is, the contaminated air is in the spiral movement of the body 52.

The inlet pipe 54 is formed integrally with the left end of the body 52, as shown in the tangential direction. In addition, the inlet pipe 54 protrudes forward from the left end of the body 52 is formed to extend.

The foreign material guide tube 56 is integrally formed at the right end of the body 52. The foreign material guide tube 56 is for guiding the flow of foreign substances in the contaminated air introduced into the body 52, and has a funnel shape that gradually decreases in diameter.

More specifically, the foreign material guide tube has an elbow shape. Thus, the upper end is directed to the left side, and the lower end is directed downward. The foreign material guide tube 56 is formed such that its diameter (inner diameter) gradually decreases toward the right side or the upper side. In other words, the foreign material guide tube 56 is formed such that its diameter gradually increases toward the left or the right.

As such, the foreign material guide tube 56 is formed so that the diameter of the lower end has the smallest size, the lower end of the foreign material guide tube 56 is the dust inlet of the dust unit 60 cover 64 to be described below ( 64 ').

The cover 64 is formed of a disc corresponding to the size of the upper end of the main body 62, the dust inlet (64 ') is formed in the center of the cover 64 through the top and bottom. The dust inlet 64 ′ is an inlet through which the foreign matter flowing through the foreign substance guide tube 56 flows into the dust unit 60. Therefore, the diameter size of the dust inlet 64 'is formed to be the same as the bottom size of the foreign material guide tube 56.

The cover 64 and the main body 62 are coupled to and separated from each other by sliding detachment. Therefore, the cover 64 and the main body 62 are further provided with a fastening means 70 for sliding and fixing the cover 64 and the main body 62 to each other. The fastening means 70 is provided at the left half of the dust unit 60 so that the left half of the cover 64 and the left half of the main body 62 are fastened to each other.

Do. That is, the cover 64 of the dust unit 60 is fixedly installed at the lower end of the foreign material guide tube 56.

It looks at the operation of the vacuum cleaner dust collection assembly according to the present invention as described above.

Although not shown first, when the suction force is generated by the rotation of the motor provided in the main body of the vacuum cleaner, the external contaminated air (outside air mixed with dust and air) through the inlet pipe 54 is the dust collecting unit It is introduced into the body 52 of the (50).

The polluted air introduced into the body 52 is pivoted in the spiral direction inside the body 52. That is, since the suction force generated by the motor (not shown) acts as the discharge pipe 58, air is to be discharged through the discharge pipe 58. Therefore, the contaminated air introduced into the body 52 at a high speed through the inlet pipe 54 does not change the direction and moves to the right while turning the inside of the body 52 (FIG. 5). Reference)

Air from the polluted air that rotates inside the body 52 is discharged through the discharge pipe 58 as shown by the solid line in FIG. 5, and foreign matter in the polluted air is guided by the foreign material as shown by the dotted line in FIG. Guided through the pipe 56 is introduced into the dust unit 60.

In more detail, the outside polluted air introduced through the inlet pipe 54 is moved to the right while turning along the inner peripheral surface of the left end of the body 52, and the air radius of the polluted air gradually decreases. It is introduced into the discharge pipe (58). In addition, foreign matters other than air in the polluted air gradually move to the right along the inner circumferential surface of the body 52, and eventually flow along the foreign substance guide tube 56 to enter the dust unit 60.

The process of separating foreign matter (dust) from the air in the dust collecting unit 50 is due to the difference in centrifugal force (遠 心力, centrifugal force). Centrifugal force is an inertia that appears on an object in circular motion. The centrifugal force is the same as the centripetal force, opposite in direction, and acts away from the center of the circle.

Therefore, when an object of mass m is moving in a constant velocity motion around the circumference of the radius r, the magnitude F of the centrifugal force (centripetal force) is F = mrω ² = mv ² / r (ω is the magnitude of the angular velocity and v = rω is the Size of circular motion), air and foreign matter (dust) having different masses are separated from each other.

In more detail, the mass of air is almost negligible, so the centrifugal force of the air turning inside the body 52 is fine so that the air is easily drawn into the discharge pipe 58 by the suction force generated by the motor (not shown). Discharged. On the other hand, the foreign matter (air) of the polluted air that rotates inside the body 52 has a relatively large centrifugal force because the mass is much larger than that of air.

Therefore, the foreign matter is continuously moved to the right while turning along the inner circumferential surface of the body 52 by centrifugal force, and eventually flows into the foreign material guide tube 56. In addition, the foreign matter guided by the foreign material guide tube 56 is dropped to the lower side is deposited inside the main body 62 of the dust unit 60.

Next, the process of removing the foreign matter (dust) accumulated in the dust unit 60 will be described with reference to FIG. 6.

At this time, the main body 62 of the dust unit 60 should be separated from the cover 64. That is, the handle 66 is pulled to the right in a state in which the user grips it by hand. In this case, the fastening protrusion 74 of the fastening means 70 moves to the right while being guided by the fastening groove 72. Thus, the main body 62 of the dust unit 60 is separated from the cover 64.

When the main body 62 of the dust unit 60 is separated as described above, the inside of the dust unit 60 is removed, or the foreign matter is removed by washing.

Then, the main body 62 of the dust unit 60 is fastened to the cover 64 again, and the process is based on the reverse order of separation of the main body 62 described above.

Specifically, as shown in FIG. 6, the main body 62 is moved to the left in a state where the main body 62 is separated to the right side of the cover 64. In this case, the front end and the rear end of the fastening protrusion 74 are inserted into the front end and the rear end of the fastening groove 72, respectively. In this state, the main body 62 is further pushed to the left side so that the fastening protrusion 74 is formed. It slides while being inserted into the fastening groove 72.

When the main body 62 is continuously pushed to the left, the left end of the fastening protrusion 74 is in contact with the left end of the fastening groove 72, so that the main body 62 is completely fastened to the cover 64. do. The state at this time is as shown in FIG.

The scope of the present invention is not limited to the above-exemplified embodiments, and many other modifications based on the present invention will be possible to those skilled in the art within the above technical scope.

For example, in the above embodiment, the case where the inlet pipe 54 is integrally formed on the upper end of the body 52 is described as an example, but in addition to the configuration, the inlet pipe 54 is the body 52. It is also possible to form a tangential direction at the bottom or the front or rear of the).

In addition, the appearance of the dust collecting unit 50 and the dust unit 60 constituting the dust collecting assembly of the present invention can be changed to various shapes in relation to the installation of other components provided in the main body (not shown) of the vacuum cleaner. Of course it can.

In the vacuum cleaner dust collection assembly according to the present invention as described above, foreign matter (dust) in the air is separated from the air by the difference in the centrifugal force. That is, the discharge pipe through which the air is discharged is located on the same central axis as the body to prevent the inflow of foreign matter. Thus, while simple compared to the conventional configuration, there is an advantage that the pressure loss is minimized and the suction force is increased compared to the prior art. In addition, noise is reduced by simplifying the flow path.

In addition, in the present invention, the foreign material guide tube for guiding the foreign matter separated from the air to form an elbow (elbow) to guide the foreign matter to the lower side, the size of the foreign material guide tube is configured to gradually decrease in diameter toward the bottom. . Therefore, as well as blocking the inflow of air into the dust unit, compared to the conventional has the effect of preventing the re-scattering of foreign matter introduced into the dust unit.

In addition, in the present invention, since the dust unit is composed of a cover and a main body, and the main body is configured to slide on and off the cover, there is also an advantage that it is easier to remove foreign matter accumulated in the main body.
