The present invention relates to a vacuum cleaner, and more particularly, to a vacuum cleaner having a dust collecting assembly for dually filtering foreign matter in the air by inertia and centrifugal force.

1 shows a configuration of a general vacuum cleaner. As shown in the drawing, the vacuum cleaner includes a main body 1 having suction means for sucking air in the room, and a suction nozzle 2 into which air on the bottom surface is introduced by suction force generated in the main body 1. Has a configuration to include.

On the other hand, the main body 1, the lower body (5) to which the suction means is received and fastened, and the parts embedded in the lower body (5) so as not to be exposed to the outside, the electric part for controlling the vacuum cleaner (not shown) It is composed of an upper body (6) that is built.

In addition, wheels 8 are fastened to both sides of the body so that the main body 1 can smoothly move the bottom surface, and the wheels 8 are separated from foreign substances sucked from the air sucked through the suction nozzles 2. A discharge portion 8a through which air of the air is discharged from the main body 1 is constituted.

Between the main body 1 and the suction nozzle 2, a suction hose 3b made of a flexible material, an operation unit 4 connected to an end of the suction hose 3b, and the operation unit 4 ) And an extension tube 3a for connecting the suction nozzle 2 are sequentially installed, so that the suction force generated in the main body 1 can be transmitted to the suction nozzle 2.

Therefore, when electricity is applied through the wire 9 connected to the power supply unit (not shown) built in the main body 1, the vacuum cleaner is in a standby state. At this time, when the user adjusts the suction step by using the button of the operation unit 4, the suction force suitable for each step is generated by the suction means built in the main body.

The suction force generated through the suction means is transmitted to the suction nozzle 2 via the suction hose 3b and the extension pipe 3a which are fastened to the suction connector 3c. The air containing the foreign matter such as dust or lint is sucked by the suction force transmitted to the suction nozzle 2, and the foreign matter in the sucked air is separated by the dust collecting assembly 10, and the filtered air is discharged. Cleaning is performed by the process of being discharged to the outside of the main body 1 through the portion (8a).

2 illustrates a dust collecting assembly 10 in a state in which a conventional dust filter 14 is fastened, so that air introduced into the main body through a suction connection portion may flow in a tangential direction along an inner wall of the dust collecting assembly. The guide suction guide 12 is molded, and the separator 13 having a hole 13a formed therein is assembled so that a large amount of dust contained in the air introduced through the suction guide 12 can be separated. The other outer wall of the suction guide part 12 is provided with a handle 15 to facilitate attachment and detachment from the main body 1.

The upper cover 11 configured to open and close the upper part of the dust collecting assembly 10 configured as described above is formed with a discharge port 11a at the center thereof, and a dust filter 14 at the bottom edge of the discharge port 11a. ) Is fastened.

The filter body 14b of the dust filter 14 has a cylindrical shape in which wrinkles in the longitudinal direction are repeated in the circumferential direction. In addition, the lower fixing portion 14a edge which fixes and supports the bottom of the filter body 14b protrudes a predetermined portion upward to surround the bottom of the filter body 14b.

It is preferable that the filter body 14b of the dust filter 14 is formed of a material that can secure a certain strength or more and take shape upon cleaning in consideration of the strong flow of air. For example, it can also be comprised by the polyester material which can be utilized as a fiber material.

In addition, the upper and lower fixing portions (not shown) and the lower fixing portion 14a for fixing and supporting the upper and lower portions of the filter body 14b are also configured so that the filter body 14b can maintain a cylindrical shape and can be washed. It can also comprise a synthetic resin material.

Since the filter body 14b is able to widen the contact surface area with the flowing air by forming a plurality of pleats in the longitudinal direction, the dust collecting efficiency is maximized. That is, it is filtered by the filter body 14b so that fine foreign matter is not included in the air discharged through the discharge port 11a.

If fine foreign matter is accumulated on the surface of the filter body 14b of the dust filter 14 through this process, the flow of air is not smoothly made. Therefore, the foreign matter on the surface of the dust filter 14 should be brushed off or washed.

As described above, since the foreign matter is attached to the dust filter 14 in the related art, there is a problem in that the dust filter 14 is separated and the attached foreign matter is removed after a certain period of use.

In addition, according to the conventional dust collection assembly 10 as described above, since foreign matters in the air are filtered by one process, foreign matters in the air such as fine dust are not properly filtered.

In addition, in the prior art as described above, air must pass through the dust filter 14 having a large number of wrinkles, and thus there is a problem of lowering suction force due to pressure loss (energy loss).

Accordingly, an object of the present invention is to solve the problems in the prior art as described above, and to provide a vacuum cleaner having a dust collecting assembly for separating the foreign matter in the air by inertia and centrifugal force.

Another object of the present invention is to provide a vacuum cleaner having a dust collecting assembly which shortens the flow path of air while filtering foreign substances in a double.

According to a feature of the present invention for achieving the above object,

First separation means for primarily separating foreign substances in the air; A plurality of second separating means provided on both sides of the first separating means and separating foreign matters in the air by cyclone flow; It is detachably installed at the lower side of the said 1st separation means and a 2nd separation means, and has a structure which includes the dust container which collects the foreign material isolate | separated by the said 1st separation means and the 2nd separation means; The suction direction of the air introduced into the first separating means and the discharge direction of the air discharged from the second separating means are opposite to each other.

According to such a structure, while having a simple structure, there exists an advantage that the foreign material in air is removed effectively.

Vacuum cleaners are widely used in general households, and the demand is increasing due to the necessity of cleaning carpets and sofas, and a canister type in which a nozzle part, which is a suction port, is provided separately from the main body and connected by a connecting pipe. And it can be roughly divided into an upright method (Upright type) in which the nozzle unit is formed integrally with the main body.

The vacuum cleaner is composed of a plurality of parts such as a suction nozzle and a motor, and in particular, the dust collecting assembly performs a function of separating and collecting foreign substances in the sucked air. In addition, the functions and configurations of the suction nozzle and the motor, etc., provided in the cleaner are described in the related art, and since they are widely known, detailed descriptions thereof will be omitted.

Therefore, hereinafter, the canister type and the upright type, as well as the cyclone dust collecting assembly which can be mounted to all types of cleaners will be described in detail.

3 to 8 show the configuration of the dust collecting assembly constituting the vacuum cleaner according to the present invention. That is, FIG. 3 is a perspective view of a dust collection assembly constituting the vacuum cleaner according to the present invention, FIG. 4 is a cross-sectional view of the portion II ′ of FIG. 3, and FIG. 5 is a perspective view of FIG. 4. have. FIG. 6 is a cross-sectional view taken along the line J-J 'of FIG. 3, and FIG. 7 is a cutaway perspective view of the right end of the dust collecting assembly constituting the vacuum cleaner according to the present invention. 8 is a perspective view illustrating a dust container cutout of the dust collecting assembly constituting the exemplary embodiment of the present invention.

As shown in these figures, the dust collecting assembly constituting the vacuum cleaner according to the present invention, the first separation means 50 for separating the foreign matter primarily by guiding air and foreign matter in different directions by the difference of inertia And second separation means 60 for separating the foreign matter in the air by centrifugal force by generating a vortex, and the foreign matter separated by the first separation means 50 and the second separation means 60 is collected. It is made of a dust container 70 and the like.

The first separating means 50 primarily filters contaminated air flowing from the outside, and here, foreign matter (dust) having a relatively large mass is filtered out. That is, the foreign matter having a relatively large size and load is filtered by the first separating means 50, and the fine foreign matter remaining in the air is filtered by the second separating means 60.

The first separating means 50 is configured to reverse the direction of travel of the air and to guide foreign matter in the air downward. That is, the first separating means 50 is a cylindrical body 52 in which the air introduced therein is rotated and protruded on one side of the body 52 to guide the suction of the body 52 of air. The suction guide tube 54 and the foreign body guide tube 56 formed on one side of the body 52 to guide the foreign matter in the air to the dust container 70, and the like.

Looking more specifically, the body 52 is formed in a '⊂' shape as shown. Therefore, the contaminated air (air mixed with air and foreign matter) introduced through the suction guide pipe 54 flows to the left side in the body 52 and is changed in direction to flow to the right side again. In addition, the air flowing to the right again flows to the upper side and flows into the second separating means 60.

In this way, the first separating means 50, the inflow direction and the discharge direction of the air is perpendicular to each other (left and top). That is, the air flowing to the left through the suction guide pipe 54 is changed to the direction inside the body 52 to flow to the right, and then again to change the direction upwards (inflow guide to be described below) It is introduced into the second separation means 60 through 63. In this way, the air flowing into the first separating means 50 flows in the left direction, and the discharged air is discharged in the upper direction, thereby being perpendicular to each other.

The suction guide tube 54 has a circular cross section, and as shown, a guide portion 54 'integrally formed on the right end of the body 52, and a right end of the guide portion 54'. And a cylindrical fastening portion 54 "extending from the right side to the right side.

The guide portion 54 ′ has a shape in which the height gradually increases toward the right side to guide the flow of air. In addition, the fastening part 54 ″ is formed in a cylinder having a predetermined length and is inserted into an air flow path formed in a peripheral part (not shown).

The body 52 is formed with a foreign material guide tube 56 through which the foreign matter filtered from the inside is discharged. The foreign material guide tube 56 is to guide the foreign matter in the body 52 is separated and discharged to the dust container 70, is formed to protrude downward from the lower end of the body (52). That is, the foreign material guide tube 56 is a '⊂' shape is formed to extend vertically from the left end of the body 52. The lower end of the foreign material guide tube 56 is coupled to the first foreign material tube 78 'of the dust container 70 to be described below.

By the configuration of the first separating means 50 as described above, foreign matter in the air is primarily separated. That is, the contaminated air introduced into the body 52 from the right outside through the suction guide pipe 54 moves along the '52' shaped body 52, and the air in the contaminated air is left at the left end. By changing the direction by the suction force is moved to the right again, foreign matter in the contaminated air is introduced into the foreign matter guide tube 56 without changing the direction by inertia.

The second separating means 60 are provided on both sides of the first separating means 50, respectively. That is, the second separating means 60 is installed left and right in front and rear of the first separating means 50, respectively, so as to be horizontal with the upper surface of the dust container 70.

The second separating means 60 is a cyclone cylinder 62 for guiding the air and foreign matter passing through the first separating means 50 to rotate in a spiral direction along an inner circumferential surface by generating a vortex, and the cyclone cylinder ( 62) an air discharge pipe 64 or the like for guiding the air turning along the inner circumferential surface in the reverse direction.

And, the second separating means 60, one or two or more are provided. In the present invention, a case in which the second separating means 60 is provided on each side of each of the first separating means 50 will be described as an example. As shown in the drawing, the second separating means 60 is provided one each in front and rear of the first separating means 50.

In more detail, the second separating means 60 is installed in the front second separating means 60 which is installed in front of the first separating means 50 and the rear of the first separating means 50. Consisting of a second rear separating means (60).

Therefore, the air and fine foreign matter discharged from the first separating means 50 are guided by the inflow guide 63 to be described below, respectively, the front second separating means 60 and the front second separating means 60. Flows separately).

The cyclone cylinder 62 has a conical shape in which the diameter (inner diameter) gradually decreases toward the left side. That is, the cyclone cylinder 62 is made of a corn shape or a funnel shape. At the right end, an inlet portion 62 'extending in a predetermined length in a cylindrical shape is formed.

Looking in more detail, the right end of the cyclone cylinder 62, the inlet portion 62 'of a predetermined size formed in a cylindrical shape is integrally formed, the inlet portion 62' is an inlet guide projecting downwards 63 is formed.

The inflow guide 63 is formed in contact with the inflow portion 62 'of the cylindrical shape in a tangential direction (see FIG. 5). Therefore, air and fine foreign matter introduced into the inlet 62 ′ through the inlet guide 63 are pivoted along the inner circumferential surface of the cyclone barrel 62.

Referring to Figure 7 looks at the configuration of the inflow guide 63 in more detail.

In the front second separating means 60 and the front second separating means 60, the air discharged from the first separating means 50 receives the front second separating means 60 and the front second separating means 60. A front inlet guide 63 'and a rear inlet guide 63 "are formed to guide each other, and the front inlet guide 63' and the rear inlet guide 63" are formed symmetrically with each other. That is, the front inflow guide 63 'is formed at the rear end of the front second separating means 60 in a tangential direction, and the rear inflow guide 63 "is formed at the front end of the second rear separating means 60. It is formed in the tangential direction.

Therefore, the air flowing into the second separating means 60 through the inflow guide 63 rotates in the counterclockwise direction in the front second separating means 60 ′, which is relatively forward, and relatively at the rear side. Inside the rear second separating means 60 "is rotated clockwise.

The lower end of the inflow guide 63 is connected to the rear end of the body 52 of the first separating means 50. Therefore, the air flowing along the inside of the body 52 moves to the lower right end of the body 52, and then into the second separating means 60 in the front and rear through the inflow guide 63. It is coming in.

The cyclone cylinder 62 guides the air primarily purified by the first separating means 50 to flow in a spiral direction together with the fine foreign matter. That is, air and fine foreign matter introduced into the cyclone cylinder 62 through the inflow guide 63 are moved in a spiral direction along the inner circumferential surface of the cyclone cylinder 62 while moving to the left.

Since the inner diameter of the cyclone cylinder 62 gradually decreases toward the left side, the rotation cycle of air and fine foreign matter moving to the left while turning along the inner circumferential surface of the cyclone cylinder 62 becomes faster.

When air and foreign matter flow in the cyclone cylinder 62 having a cone shape as described above, a dust devil is generated inside the cyclone cylinder 62. That is, the vortex of air, also called whirlwind, occurs, and the air and the fine foreign matter turn along the inner circumferential surface of the cyclone cylinder 62, and the air flow in the opposite direction to the external swirl flow in the center (air flow in the right direction) ) Is formed. In this way, the air flows back in the center of the second separation means 60.

The air discharge pipe 64 guides only the air flowing in the cyclone barrel 62 and the air out of the fine foreign matters to be discharged to the outside. It is installed from side to side. More specifically, the air discharge pipe 64 is installed so that the left side portion is located inside the inlet portion 62 'and the right side portion protrudes outward to the right side of the cyclone cylinder 62.

Therefore, the air flowing in the cyclone cylinder 62 and the air among the fine foreign matter move to the left in the cyclone cylinder 62 to the air discharge pipe 64 by the suction force of a motor (not shown). Sucked and discharged to the right outside.

In addition, the suction guide pipe 54 for guiding the inflow of air into the first separating means 50 and the air discharge pipe 64 for guiding the purified air from the second separating means 60 to be discharged to the outside. Are formed at the same position as each other, and the directions of the air introduced through the suction guide pipe 54 and the air discharged through the air discharge pipe 64 are parallel to each other.

That is, the suction guide tube 54 is located at the right end of the first separating means 50, and the air discharge pipe 64 is also located at the right end of the second separating means 60. And, the air introduced through the suction guide pipe 54 is directed to the left side, the air discharged through the air discharge pipe 64 is directed to the right, such suction guide pipe 54 and the air discharge pipe ( The air flowing through 64) flows horizontally so that they are parallel to each other.

Looking more specifically at the air flow in the second separating means 60, the air flow inside the cyclone barrel 62 is similar to the principle of 'eye of typhoon'. That is, since the suction force of the motor (not shown) acts on the air discharge pipe 64, air flow in the right direction occurs in the central portion of the cyclone cylinder 62, and the inner circumferential surface of the cyclone cylinder 62 Along this, a swirl flow to the left is formed.

As such, a swirling airflow is formed near the inner circumferential surface of the cyclone cylinder 62 to move to the left side, and an opposite airflow is formed at the center portion so that air moves to the right side, which is the air discharge pipe 64. Is discharged to the right along. This corresponds to the formation of a downdraft, unlike the rising air on the outside, in the center of the 'eye of typhoon' or 'yongore'.

On the other hand, the fine foreign matter flowing along the inner circumferential surface of the cyclone cylinder 62 does not change the direction by centrifugal force, and continues to the left to be guided to the connecting pipe 66 to be described below.

Looking at the air flow inside the second separation means 60 in more detail, the air and the fine foreign matter turning inside the cyclone cylinder 62 has a centrifugal force (遠 心力). 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.

That is, since the mass of air can be almost negligible, the centrifugal force of the air orbiting the inside of the cyclone cylinder 62 is minute, and the air is drawn to the air discharge pipe 64 by the suction force generated by the motor (not shown). It is easily sucked in. On the other hand, the foreign matter turning along the inner circumferential surface of the cyclone cylinder 62 has a relatively large centrifugal force because the mass is much larger than air, and thus has a large radius of rotation.

Therefore, the foreign matter is continuously moved to the left while turning along the inner circumferential surface of the cyclone cylinder 62 by the centrifugal force, and eventually flows into the connecting pipe 66 to be described below. In addition, the foreign matter guided to the connecting pipe 66 falls down and flows into the dust container 70.

The left side of the cyclone cylinder 62 is provided with a connection pipe (66). The connecting pipe 66 is formed up and down on the left side of the second separation means 60 as shown. That is, the right side is in contact with the left end of the cyclone cylinder 62, the lower end is in contact with the upper surface of the dust container (70). That is, the connecting pipe 66 is installed on the upper side of the dust container 70, and is formed perpendicular to the upper surface of the dust container 70.

Therefore, the fine foreign matter (dust, etc.) moving to the left while turning along the inner circumferential surface of each cyclone cylinder 62 constituting the plurality of second separation means 60 is the dust container 70 through the connecting pipe 66. Will be guided inside.

The connecting pipe 66 is formed such that its cross-sectional area gradually decreases toward the dust container 70 side. That is, the size of the inner cross-sectional area of the connecting pipe 66 decreases toward the lower side. This is to prevent the foreign matter introduced into the dust container 70 through the connecting pipe 66 is scattered upward through the connecting pipe 66 again.

The interior of the connecting pipe 66 is preferably divided into two parts. That is, the foreign material barrier 66 'is formed in the inner center portion of the connecting pipe 66 vertically, and partitions the inside of the connecting pipe 66 back and forth. Therefore, the foreign matter separated from the plurality of second separating means 60 provided at the front and rear of the first separating means 50, respectively, through the front and rear passages formed in the foreign material barrier 66 ′, respectively. You are guided to.

Two spaces are formed in the dust container 70. That is, the inside of the dust container 70, the first dust collecting unit 72, the foreign matter separated by the first separating means 50 is collected, and the foreign matter separated by the second separating means 60 is collected. The second dust collecting unit 74 is divided into. That is, a barrier 76 is formed in the dust container 70 to partition the left and right spaces. A first dust collecting part 72 is formed on the right side of the barrier 76 and a second dust collecting part on the left side thereof. 74) is formed.

The first dust collecting part 72 and the second dust collecting part 74 are integrally formed as shown, and the barrier 76 has an arc-shaped cross section. That is, as shown, the barrier 76 has a circular arc shape protruding round the center portion to the right.

On the upper surface of the dust container 70, the foreign material discharge pipe 78 is connected to the lower end of the foreign material guide tube 56 and the connecting pipe 66 is formed in a predetermined size, respectively. More specifically, the foreign substance discharge pipe 78 is formed extending from the upper surface of the first dust collecting part 72 to the upper side and coupled to the lower surface of the foreign material guide tube 56, the first foreign material tube 78 ', and the second It is formed of a second foreign material tube 78 "extending from the upper surface of the dust collecting portion 74 and coupled to the lower end of the connecting pipe 66.

The first foreign material pipe 78 ′ and the second foreign material pipe 78 ″ serve as an inlet through which foreign matter enters the dust container 70, and at the same time, the foreign material guide pipe 56 and the connection pipe 66 may be formed. And the first foreign material pipe 78 'and the second foreign material pipe 78 "have a rectangular shape corresponding to the lower ends of the foreign material guide pipe 56 and the connection pipe 66, respectively. Shaped to have a cross section, and inserted into the lower end of the foreign material guide tube 56 and the connecting pipe 66, respectively.

As such, the dust container 70 is mounted to be easily separated from the first separating means 50 and the second separating means 60. That is, the lower ends of the foreign material guide tube 56 and the connecting pipe 66 are coupled to the foreign material discharge pipe 78 to be detachable.

On the other hand, the bottom cover 70 'is detachably coupled to the lower end of the dust container 70. The lower cover 70 ′ shields a lower portion of the dust container 70, and is fitted to the bottom of the dust container 70 by interference fit. Therefore, when the lower cover 70 'is peeled off, the foreign matter inside the dust container 70 falls naturally and is discharged to the outside.

It looks at the state in which the vacuum cleaner and the dust collection assembly according to the present invention as described above are used.

First, although not shown, 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 suction guide pipe 54 is It is introduced into the body 52 of the first separation means (50). At this time, the air sucked is moved to the left in the upper half of the body (52).

Air reaching the left end of the body 52 changes direction and flows to the right again. That is, since the suction force generated by the motor (not shown) acts as the inflow guide 63 connected to the lower right end of the body 52, air is separated through the inflow guide 63. Attempt to move to means 60.

Therefore, the contaminated air introduced into the body 52 at a high speed through the suction guide pipe 54 is moved to the right by turning the direction again at the left end of the body 52 having a '⊂' shape. (See 'solid line' arrow in FIG. 4)

On the other hand, foreign matter introduced with the air into the body 52 through the suction guide pipe 54 enters into the lower dust container 70 through the foreign matter guide pipe 56. That is, the foreign matter flowing in the body 52 does not change direction at the left end of the body 52, flows along the inner surface of the body 52, and passes through the foreign material guide tube 56 to allow the first dust collecting part ( 72) It is introduced inside.

The foreign matter separation in the first separation means 50 is due to the difference in inertia force between the air and the foreign matter. In more detail, since the inertial force is 'F (inertia force) = m (mass) x a (acceleration)', the mass of the air is negligibly negligible and the air flows inside the body 52. Is easily discharged to the inflow guide 63 by a suction force generated by a motor (not shown).

On the other hand, the mass of the foreign matter (air) of the polluted air that rotates inside the body 52 is relatively much larger than the air, thereby having a relatively large inertia. Therefore, the foreign matter reaching the left end of the body 52 moves along the inner left side of the body 52 while drawing a relatively large circle and is introduced into the foreign material guide tube 56 as it is.

The foreign matter introduced into the foreign material guide tube 56 is naturally accumulated by gravity without entering an external force and is accumulated inside the first dust collecting part 72 of the dust container 70. In this case, the foreign matter separated by the first separating means 50 and accumulated in the first dust collecting part 72 becomes a foreign material having a relatively larger size and load than the foreign matter accumulated in the second dust collecting part 74.

On the other hand, the mixed air (air mixed with air and fine foreign matter) moved to the lower right end of the body 52 is introduced into the second separation means 60 through the inlet guide (63). The air introduced into the second separating means 60 is air purified primarily by the first separating means 50, but it contains fine foreign matter (dust) which is still relatively low in mass.

Air and dust flowing into the plurality of second separation means 60 through the inlet guide 63 enters the inlet 62 '. In this case, since the inflow guide 63 is in tangential direction to each of the inflow portions 62 ', spiral flow occurs in the inflow portion 62' and the cyclone barrel 62. As shown in FIG.

That is, as described above, the air and the dust introduced into the inlet 62 'are rotated along the inner circumferential surface of the inlet 62' by the suction force. As shown in FIG. 7, the air introduced into the second separating means 60 through the inflow guide 63 rotates counterclockwise in the front second separating means 60 ′ which is relatively forward. It rotates clockwise in the rear second separating means 60 ″ which is relatively rearward.

Inside the second separating means 60, air gradually moves to the left side of the cyclone cylinder 62. Since the diameter of the cyclone cylinder 62 gradually decreases toward the left side, rotation cycles of air and dust moving to the left side inside the cyclone cylinder 62 gradually increase.

The air that has been moved to the left in the cyclone barrel 62 is changed again to move to the right through the center portion of the cyclone barrel 62, in which the air is guided through the air discharge pipe (64) do.

That is, as described above, due to the suction force generated by the motor (not shown), the air inside the cyclone barrel 62 is right-sided through the air discharge pipe 64 as shown by the solid line in FIG. 6. However, first, air and foreign substances introduced at high speed through the inflow guide 63 are moved to the left along the inner circumferential surface of the cyclone cylinder 62 by inertia and centrifugal force.

As described above, when air and dust are turned along the inner circumferential surface of the cyclone cylinder 62, air flows formed thereon are formed at the central portion thereof. Air flow to the bed occurs. Therefore, the air moved to the left side of the cyclone cylinder 62 flows back to the air discharge pipe (64).

Such foreign matter (dust) in the air is separated by the flow inside the cyclone cylinder 62. That is, the air and dust flowing inside the cyclone cylinder 62 is gradually moved to the left while turning the inner circumferential surface of the cyclone cylinder 62 by centrifugal force, where pure air having a relatively low mass easily changes direction. While entering the air discharge pipe 64, fine foreign matter (dust) continues to move to the left while turning the inside of the cyclone cylinder 62 by centrifugal force, and eventually guided by the connecting pipe 66 The second dust collecting part 74 is dropped into the inside.

As such, inside the second separating means 60, the fine foreign matter in the air continues to flow in the first one direction, while the air flows back in the opposite direction. Therefore, foreign matters that cannot flow back are separated from the air and discharged.

In this way, in the vacuum cleaner dust collecting assembly according to the present invention, foreign matters in the air are filtered twice. In addition, the directions of the air entering and exiting the vacuum cleaner dust collecting assembly of the present invention are opposite to each other. That is, the suction direction (left direction) of the air flowing into the first separating means 50 and the discharge direction (right direction) of the air discharged from the second separating means 60 are opposite to each other.

Therefore, both the suction guide tube 54 for guiding air suction and the air discharge tube 64 for guiding the discharge of air are located at the right side of the vacuum cleaner dust collecting assembly according to the present invention.

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.

In the vacuum cleaner according to the present invention as described above, foreign matter in the air is dually filtered by the first separation means and the second separation means using centrifugal force. As such, since foreign substances in the air are filtered twice, there is an advantage that the removal of foreign substances in the air is more effective than in the related art.

In addition, in the present invention, the dust collecting assembly is configured to separate foreign matter in the air primarily by inertia and secondly to separate foreign matter by cyclone flow. Therefore, since the overall structure is simple, the flow loss (energy loss) of the air is prevented and the cleaning efficiency is improved. That is, there is an effect that the lowering of the suction force of the cleaner is prevented.

In addition, in the present invention, the dust container constituting the dust collecting assembly is detachably installed, and since the lower surface cover is provided at the lower portion, it is easier to remove the foreign matter accumulated in the dust container.
