BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dust collector for a vacuum cleaner which filters cleaning materials such as dust and hair in the intake air in a cyclone method, and in particular, the cleaning material in the intake air is continuously passed through the first and second cyclones. Filter by the cyclone method, the mesh is installed between the first and second cyclones to catch a relatively large cleaning material such as hair, etc., but the cleaning performance by adjusting the shape of the primary cyclone and the installation position of the mesh It relates to a dust collector for a vacuum cleaner that can further improve.

In general, a vacuum cleaner generates a suction force of a vacuum, sucks air, passes various filters, and filters dust in the air to clean the room.

Such vacuum cleaners can be divided into cylinder type, upright type, hand type, etc. according to the usage and moving method. The floor type is mainly used for cleaning dust, such as dust, for home use. It is easy to clean the floor of the back, and the hand type is easy to clean the small area such as the stairs and the desk.

In addition, the vacuum cleaner can be divided into filter type and cyclone type according to the method of filtering the cleaning material such as dust and hair from the intake air, and the filter type passes the air containing the cleaning material through a kind of cloth bag. While the dust bag needs to be replaced periodically because it filters, the cyclone type rotates the suction air containing the cleaning material so that the cleaning material contained in the suction air falls to the floor by its own weight while descending. The dust bag is not needed and has been applied recently.

In addition, the cyclone type vacuum cleaner was developed to improve cleaning performance by allowing the cleaning material to be filtered twice while passing through the inner / outer cyclone.

1A and 1B are a perspective view and a side cross-sectional view showing an example of a dust collector for a conventional vacuum cleaner.

Looking at an example of a conventional double cyclone for a vacuum cleaner with reference to Figures 1a and 1b, a conical inner cyclone (4) is provided inside the cylindrical outer cyclone (2), the inner cyclone (4) The outer peripheral surface is provided with a mesh (6) for filtering the cleaning material from the air rising from the bottom surface of the outer cyclone (2) and the scattering prevention portion (6a) to prevent the cleaning material from being scattered again, An extension 8 is provided below the inner cyclone 4 so as to contact the inner surface of the outer cyclone 2, and as a result, between the upper side of the extension 8 and the inner surface of the outer cyclone 2. The outer dust container 9a is formed at the same time, and the inner dust container 9b is formed between the lower part of the expansion part 8 and the bottom surface of the outer cyclone 2.

At this time, a pair of suction passages 2a are formed on the inner upper side surface of the outer cyclone 2 so as to allow the intake air to flow therein, and at the same time, the upper surface of the outer cyclone 2 discharges the filtered material. While the discharge passage 2b is formed as much as possible, the chambers 4a on both sides are formed on the outer upper surface of the inner cyclone 4 so that the air passing through the mesh 6 can be introduced therein.

Therefore, when the suction force is generated, the suction air containing the cleaning material is lowered while rotating along the inner surface of the outer cyclone 2 through the suction passage 2a, and the cleaning material in the suction air is caused by its own weight. After falling to be accumulated in the outer dust container (9a), the air is first filtered by the cleaning material in the outer cyclone (2) is raised, even if the cleaning material re-fly with the air to the scattering prevention portion (6a) Hit and fall again.

Thereafter, the air passing through the outer cyclone 2 descends while rotating along the inner surface of the inner cyclone 4 through the chamber 4a, and the remaining cleaning material in the air is dropped by its own weight. The inner dust container (9b) is to be stacked, and the air secondary to the cleaning material filtered in the inner cyclone (4) is raised to be discharged along the discharge passage (2b).

Of course, the cleaning material filtered from the outer cyclone 2 and the inner cyclone 4 is accumulated in the outer dust container 9a and the inner dust container 9b, and the lower part of the outer cyclone 2 is decomposed. The cleaning material may be discarded, or may be configured to discharge the cleaning material downward.

However, in the double cyclone type dust collector as described above, the inner cyclone 4 is installed inside the outer cyclone 2, and the expansion part 8 is disposed below the inner cyclone 4. Since the external dust container (9a) and the inner dust container (9b) is formed to be divided so that the volume of each dust container (9a, 9b) can be limited, there is a cumbersome problem to remove the cleaning material frequently.

In addition, the double cyclone dust collector as described above is cleaned because the hollow cone-shaped mesh 6 inside the cylindrical outer cyclone 2 and the inner cyclone 4 of the hollow cone shape are installed vertically therein. In order to improve the performance, the outer cyclone 2 and the mesh 6 and the inner cyclone 4 can be elongated in the vertical direction, but there is a problem in that the height of the product is increased so that it is difficult to be incorporated in the vacuum cleaner. .

Figure 2 is a partial cutaway perspective view showing another example of a conventional dust collector for a vacuum cleaner.

Looking at another example of a conventional double cyclone for a vacuum cleaner with reference to Figure 2, the cylindrical inner cyclone 12 smaller than the main body 11 is formed in the center of the cylindrical body 11, the main body 11 And a plurality of conical outer cyclones 14 are arranged at regular intervals in the circumferential direction so as to abut between the inner cyclone 12 and the mesh 16 is installed at the center of the inner cyclone 12 at the same time. At the bottom of the mesh 16 is formed a shatterproof portion 18 extended to be inclined downward to prevent the cleaning material filtered from the inner cyclone 12 to rise with the rising airflow.

In this case, an inlet pipe 12a through which the suction air flows into the inner upper surface of the inner cyclone 12 is formed to penetrate the main body 11 and the inner cyclone 12 and the outer cyclones ( An outflow pipe (not shown) for allowing the air passed through 14 to flow out is formed on the upper side of the main body 11, and an inlet port (not shown) for introducing air into the upper side and the lower end of the outer cyclone 14, respectively. ) And a dust outlet 14a through which the cleaning material such as dust is discharged, and an outlet 14b through which the cleaning material is filtered is discharged.

Of course, the air filtered by the cleaning material while passing through the inner cyclone 12 rises and flows into each of the upper sides of the outer cyclones 14, and the cleaning material is passed through the outer cyclones 14. The filtered air is formed to communicate with each other to be discharged to the outside.

In addition, an inner cleaning bin 19a is formed on a bottom surface of the inner cyclone 12 to accumulate the cleaning material filtered from the inner cyclone 12, and a bottom between the main body 11 and the inner cyclone 12. On the surface is formed an external dust container 19b in which the cleaning material filtered by the external cyclones 14 is accumulated.

Therefore, when the suction force is generated, the suction air containing the cleaning material descends while rotating along the inner surface of the inner cyclone 12 through the inlet pipe 12a, and the cleaning material in the suction air is caused by its own weight. After falling off to accumulate in the inner dust container (19a), the air filtered primarily by the cleaning material in the inner cyclone 12 rises.

At this time, even if the cleaning material accumulated in the inner dust container 19a with the air rising from the bottom surface of the inner cyclone 12 rises again, it is hit by the scattering prevention unit 18 and the cleaning material is again washed with the inner dust container ( Fall on 19a).

Thereafter, the air passing through the inner cyclone 12 descends while rotating along the inner surface of each outer cyclone 14 through each inlet of the outer cyclones 14, and residual cleaning material in the air is lowered. Due to its own weight, it is dropped through the dust outlet 14a of each external cyclone to be accumulated in the external dust container 19b, and the air filtered by the cleaning material in the external cyclones 14 is raised to the outside. Each outlet 14b of the cyclones and the outlet along the outlet pipe.

Of course, the cleaning material filtered from the inner cyclone 12 and the outer cyclones 14 may be accumulated in the inner dust container 19a and the outer dust container 19b, and the lower part of the main body 11 may be disassembled. The cleaning material may be discarded, or may be configured to discharge the cleaning material downward.

However, such a double cyclone dust collector is installed outside the inner cyclone 12 so that the outer cyclones 14 are arranged in the circumferential direction, and the inner cyclone 12 and the outer cyclone The inner dust bin 19a and the outer dust bin 19b are formed at the bottom of the clones 14, respectively, so that relatively little cleaning material is filtered around the inner dust bin 19a, which is relatively filtered. Since the external dust container 19a is installed, the internal dust container 19a cannot be directly observed, and thus, there is a problem that it is difficult to empty the cleaning material such as hair, dust, etc. collected relatively in the internal dust container 19a at an appropriate time.

In addition, the double cyclone dust collector as described above has a hollow conical mesh 16 installed on the inner side of the cylindrical inner cyclone 12 at the same time and a hollow conical outer cyclone 14 on the outer side thereof. The inner cyclone 12 and the inner cyclone 12 and the mesh 16 and the outer cyclone 14 are all installed vertically so as to be arranged in a plurality of directions. Although the mesh 16 and the outer cyclones 14 can be elongated in the vertical direction, there is a problem in that the height of the product becomes high, making it difficult to embed in the vacuum cleaner.

The present invention has been made in order to solve the above problems of the prior art, so that the dust container of the secondary cyclone to filter the cleaning material in the secondary cyclone of the primary cyclone to filter the cleaning material is built first. Therefore, the object of the present invention is to provide a dust collector for a vacuum cleaner that can maximize the storage capacity as well as visualize the dust bin of the first cyclone, in which a relatively large amount of cleaning material is filtered.

In addition, the present invention is to change the shape of the vertical cyclone or in between the installation of the mesh even if the installation of the cyclone in the vertical direction and the inclined vertical cyclone through which the air passes in a limited space, An object of the present invention is to provide a dust collector for a vacuum cleaner that can further improve cleaning performance by increasing the flow length of air.

The dust collector for a vacuum cleaner according to the present invention for solving the above problems includes a first cyclone in which a cyclone flow guide communicating with an inflow pipe is installed inside a first dust container; A mesh installed inside the cyclone flow guide; A secondary cyclone having a secondary dust bin communicating with a plurality of cyclone units installed around the cyclone flow guide; The mesh and the cyclone unit is made of a flow path guide means which is installed to communicate with each other; The cyclone flow guide is formed in the inlet for communicating with the inlet pipe inlet air, a pair of outlets for allowing air to flow in and out of the primary dust container is formed at a predetermined interval in the circumferential direction with the inlet It features.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

3 to 5 is a perspective view and an exploded perspective view and a side cross-sectional view showing a part of the vacuum cleaner dust collector according to the present invention, Figure 6 is a cyclone flow guide and mesh in the dust collector for vacuum cleaner according to the present invention The top view shown.

3 to 6, the dust collecting device for the vacuum cleaner according to the present invention includes a primary cyclone 110 for filtering cleaning material from a suction air in a vertical cyclone manner, and the primary cyclone. It is installed inside the clone 110 so as to be eccentric with respect to the secondary cyclone 120 and the first and second cyclone (110, 120) to filter the cleaning material from the air in the vertical cyclone method inclined And the mesh 130 filtering the relatively large cleaning material before the air rising from the primary cyclone 110 flows into the secondary cyclone 120 and the air passing through the mesh 130. It consists of a flow path guide means 140 for guiding the flow to the secondary cyclone (120).

Here, the primary cyclone 110 is a cyclone flow path guide 112 and the cyclone flow path guide 112 is a hollow cone-shaped cleaning material collected from the cyclone flow path guide 112 is collected It consists of a first dust bin 114, the inlet pipe 110a which is obliquely communicated with the upper end of the cyclone flow path guide 112 is installed on one side of the primary dust bin 114.

At this time, the cyclone flow path guide 112 is formed at an upper end of the inlet opening (112a) in communication with the inlet pipe (110a), the predetermined distance in the circumferential direction in the flow direction of the air from the inlet (112a) A secondary outlet 112b through which air flows in and out is formed at the same time, and a main outlet 112c through which air flows in and out at a predetermined distance in the circumferential direction in the flow direction of air from the auxiliary outlet 112b is formed. The auxiliary outlet 112b and the main outlet 112c are formed so that a part of the circumferential direction is cut in the cyclone flow path guide 112 so as to be elongated in the longitudinal direction of the cyclone flow path guide 112.

Of course, the cyclone flow guide 112 is installed so as to be built in the center of the primary dust container 114 to secure a space for forming a predetermined discharge flow path at the upper end and at the same time to secure a space for dust accumulation at the lower end. .

In particular, in the cyclone flow path guide 112, the inlet 112a is installed so that a separate suction guide (g) protrudes on one side of the flow path guide 112, the air is the inner wall of the cyclone flow path guide 112 In order to flow along, the outlet 112c is preferably located on the side opposite to the inlet 112a, the auxiliary outlet 112b is located between the inlet 112a and the outlet (112c). It is preferable.

At this time, the air introduced into the cyclone flow path guide 112 through the inlet 112a is introduced into the primary dust container 114 through the auxiliary outlet 112b and the outlet 112c to clean the material. Even though the part of the filter is filtered, a part of the filter is introduced into the auxiliary outlet 112b and the outlet 112c again in a state in which the cleaning material is not filtered. In this way, the auxiliary outlet outlet close to the flow distance of air from the inlet 112a is provided. While air containing a relatively large amount of cleaning material flows in and out through 112b), air containing a relatively small amount of cleaning material flows in and out through the outlet 112b, where the flow distance of air is far from the inlet 112a. Therefore, the auxiliary outlet 112b through which the relatively dirty air can be introduced is formed to have a smaller size in the circumferential direction than the outlet 112c. It is preferred.

In addition, the primary dust container 114 is installed so that the cup-shaped pedestal 114b is coupled to the cylindrical body 114a, so that the pedestal 114b can be separated from the main body 114a. 114a) and easy to discharge the cleaning material collected in the pedestal (114b).

Next, the secondary cyclone 120 is an inclined hollow conical cyclone units 122 installed at regular intervals in the circumferential direction around the cyclone flow guide 112 and the cyclone units ( The second dust container 124 is installed to communicate with the lower end of the 122 and the cleaning material filtered by the cyclone units 122 is collected, the cyclone units 122 are the inlet pipe 110a ) Is preferably not installed at the portion in communication with the cyclone flow path guide (112).

In this case, the cyclone units 122 are formed so that the diameter thereof becomes narrower from the top to the bottom in order to increase the cyclone effect, and further, the cyclone units 122 may be installed in close contact with the cyclone flow guide 112. Is installed to be inclined downward toward the center toward the lower end, the cyclone units 122 is preferably formed to be integrally formed with the cyclone flow path guide (112).

Of course, even if the cyclone units 122 are installed to be inclined even though they maintain the same height as the cyclone flow path guide 112, the cyclone units 122 may increase the flow path of air, thereby further improving cleaning performance.

In addition, the secondary dust container 124 is formed so that the upper surface is in communication with the cyclone units 122 and is blocked to contact the cyclone flow path guide 112, while the bottom surface is formed cylindrical It is formed in a cap shape, the bottom surface is installed to be in close contact with the pedestal (114b) so that the cleaning material passed through the cyclone units 122 are also collected in the secondary dust container 124 and the pedestal (114b). do.

Of course, since the secondary dust container 124 is installed inside the primary dust container 114, the pedestal 114b is separated and collected in the primary dust container 114 and the secondary dust container 124. Make sure to discharge the cleaning materials all at once.

Usually, as the cleaning material is first filtered by the cyclone flow guide 112, a relatively large amount of cleaning material is collected in the primary dust container 114, whereas the cleaning material is secondary by the cyclone units 122. As the cleaning material is filtered, relatively little cleaning material is collected in the secondary dust container 124. As the secondary dust container 124 is formed inside the primary dust container 114, the second dust container 124 is formed. The storage capacity of the primary dust container 114 can be maximized.

Next, the mesh 130 may be formed in a cylindrical shape, but is formed in a hollow conical shape smaller than the cyclone flow guide 112 so that the mesh 130 may be installed inside the cyclone flow guide 112. 132 is installed to hang at the same time a plurality of through-holes are formed on the side 134 so that relatively large cleaning material is caught even though air passes.

At this time, the mesh 130 is installed so that the upper end is suspended, it is preferable to be installed so as to be eccentric in the direction different from the secondary outlet (112b) or the outlet (112c) inside the cyclone flow path guide (112).

Specifically, the cyclone flow guide 112 and the first and second dust bins 114 and 124 are installed so that each center passes through the center line C, while the mesh 130 has its center eccentric from the center line. It is preferable to be installed on a straight line A, but installed so as to be eccentric in a direction opposite to the auxiliary outlet 112b through which air containing a relatively large amount of cleaning material flows in and out.

Next, the flow guide unit 140 is a horizontal portion 142 which is horizontally installed on the upper end of the primary dust container 114 to communicate with the upper end 132 of the mesh and the upper end of the cyclone units 122. ) And a cyclone cover 144 installed above the horizontal part 142 to form a predetermined space between the horizontal part 142 and the air passing through the cyclone units 122. And a plurality of spiral guides 146 installed between the horizontal portion 142 and the cyclone cover 144 to allow air passing through the mesh 130 to enter the cyclone units 122. It consists of a plurality of cylindrical exhaust pipe 148 for discharging the air passing through the cyclone units 122.

In more detail, the horizontal portion 142 is the cyclone unit at the same time the center of the seating hole 142a is formed on a straight line (A) eccentric from the center line (C) so that the upper end 132 of the mesh is seated Although a plurality of communication holes 142b communicating with the upper end of the field 122 are formed, the communication holes 142b are formed at a predetermined interval in the circumferential direction around the seating hole 142a, The center is formed to be located on the center line (C).

In addition, the cyclone cover 144 has a cap shape, the exhaust port 144a is formed in a position corresponding to the communication holes 142b on the upper surface, respectively, the position corresponding to the mesh 130 on the upper surface, A discharge passage guide 144b protruding downward toward the center on the straight line A is formed to guide the air passing through the mesh 130 in a radial direction.

In addition, the spiral guides 146 may be installed such that an upper end thereof is in contact with each exhaust port 144a of the cyclone cover and a lower end thereof is in contact with the communication holes 142b of the horizontal part. Cylindrical guide body 146a having an opening (not shown) formed on an outer circumference thereof to surround 144a, and extending in a tangential direction to one side of an opening (not shown) of the guide body to form the interior of the cyclone units 122. A tangential guide 146b that forms a helical flow therein.

In this case, the guide main body 146a is installed to maintain the airtightness with the communication holes 142b of the horizontal part so that air passing through the mesh 130 does not leak, and the tangential guide 146b and the guide main body 146a do not leak. It is desirable to guide all of the cyclone units 122 to flow along).

In addition, the exhaust pipes 148 are cylindrically shaped so that the upper end 148a extends in a radial direction to be engaged with each exhaust port 144a of the cyclone cover, and the lower end 148b communicates with each other in the horizontal portion. In order to be located at the center inside the hole 142b, the diameter of the lower end 148b of the exhaust pipes is smaller than the diameter of each communication hole 142b of the horizontal portion, so that the air rising from the center of the cyclone units 122 Guide them through.

Looking at the operation of the present invention configured as described above are as follows.

First, when the suction force is generated, the inlet of the cyclone flow path through the inlet pipe (110a) installed so that the suction air communicates with the main body 114a of the primary dust container and one side of the cyclone flow path guide 112. Sucked into 112a, while rotating along the inner wall surface of the cyclone flow guide 112, some of the suction air is first discharged through the auxiliary outlet 112b, and the remainder is discharged through the outlet 112c. It is discharged secondarily and flows into the primary dust container 114.

At this time, even though air flows to the first dust container 114 through the auxiliary outlet 112b and the outlet 112c, some of them are again introduced through the auxiliary outlet 112b and the outlet 112c. While the polluted air containing a large amount of cleaning material is introduced from the auxiliary outlet 112b close to the inlet 112a, the air is partially filtered from the outlet 112c far from the inlet 112a. Is introduced.

Of course, since the auxiliary outlet 112b is formed to be relatively smaller than the outlet 112c, air is collected through the oil outlet 112c rather than the air through the auxiliary outlet 112c. It can improve performance.

On the other hand, the air introduced into the primary dust container 114 through the auxiliary outlet 112b and the outlet 112c flows inside the primary dust container 114, and cleaning material such as dust contained therein is introduced. After being collected and filtered by the primary dust bin 114 by its own weight, the air inside the primary dust bin 114 again flows through the auxiliary outlet 112b and the outlet 112c and rises, but the mesh ( 130, the larger cleaning material such as hair is filtered again.

In this case, since the mesh 130 is installed in a direction opposite to the auxiliary outlet 112b, even when the air containing a large amount of cleaning material is directly re-introduced through the auxiliary outlet 112b, the auxiliary outlet 112b is closed. It is formed smaller than the outlet (112c) to allow less air to be introduced, while relatively small air containing the cleaning material to be re-introduced through the outlet (112c).

In addition, even though air containing a relatively large amount of cleaning material is introduced into the cyclone flow guide 112 through the auxiliary outlet 112b, the mesh 130 is not directly passed through the mesh 130. Since it is separated from the outlet 112b to flow along the inner wall surface of the cyclone flow path guide 112, and exits again through the secondary outlet 112b and the outlet 112c and the primary dust container 114 You can also repeat the process of filtering the material.

Next, the air passing through the mesh 130 impinges on the discharge passage guide 144b of the cyclone cover and diffuses in the radial direction, and then is guided by the spiral guides 146 to guide the cyclone units 122. Inflow along the upper side of the), and the air introduced in this way is moved from the top to the bottom while rotating along each inner wall of the cyclone units 122, and at the same time residual cleaning material such as fine dust contained in the air As it passes through the cyclone units 122, it is filtered by its own weight and collected in the secondary dust bin 124.

In this case, the cyclone units 122 are arranged at a predetermined interval on the outer circumference of the hollow conical cyclone flow guide 112, and is formed to be inclined downward toward the center from the top to the bottom to the cyclone units ( The flow path of air passing through 122) can be increased to further improve the cleaning performance.

Next, the air filtered through the cyclone units 122 and the remaining cleaning material is again raised along the cyclone units 122 and then the exhaust pipe communicating with the upper center of the cyclone units 122. To exit completely through the field 148.

7 and 8 are graphs showing the dust decomposition performance according to the shape of the cyclone flow guide and the installation position of the mesh in the dust collector for the vacuum cleaner according to the present invention.

As shown in FIG. 7, the auxiliary outlet 112b and the outlet 112c are formed in the case of (A) in which only the outlet 112c is formed in the cyclone flow guide 112. In the case of the formed (B), the flow rate of the air and the dust separation performance according to it, respectively, are as follows.

Specifically, in the case of (A) in which only the outlet 112c is formed in the cyclone flow guide 112, the air at the outlet 112c is positioned at a height (z = 100) parallel to the inlet pipe 110a. At the same time, the flow velocity of air is rapidly observed at the position (z = 118) at the top of the mesh 130 and at the eccentric position before being discharged to the outlet 112c. Was tested by exposing 100g to air, and the dust separation performance is about 82%.

On the other hand, in the case of (B) in which the auxiliary outlet 112b and the outlet 112c are formed in the cyclone flow guide 112, the auxiliary outlet is positioned at a height parallel to the inlet pipe 110a (z = 100). At the outlet 112b and the outlet 112c, the flow velocity of the air is observed quickly, and at the position (z = 118) at the top of the mesh 130 at an eccentric position between the auxiliary outlet 112b and the outlet 112c. The flow rate of air is observed quickly, and 100m of test dust (DMT) is exposed to air. As a result, dust separation performance is about 87%.

As a result, in the case of (B) in which the secondary outlet 112b and the outlet 112c are formed in the cyclone flow guide 112, only the outlet 112c is formed in the cyclone flow guide 112 (A). In the case of), it can be seen that the dust separation performance is superior because the air is discharged to the primary dust container 114 twice to increase the flow distance and flow time of the air more.

In addition, as shown in FIG. 8, the mesh 130 is installed at a central position of the cyclone flow guide 112 in which the auxiliary outlet 112b and the outlet 112c are formed, and the auxiliary. Looking at the flow rate of the air and the dust separation performance according to the case (B) in which the mesh 130 is installed in the eccentric position of the cyclone flow guide 112 formed with the outlet 112b and the outlet 112c, As follows.

Specifically, in the case where the mesh 130 is installed at the central position of the cyclone flow guide 112 in which the auxiliary outlet 112b and the outlet 112c are formed, the mesh 130 is parallel to the inlet pipe 110a. At the height position (z = 100), the air flow velocity around the mesh 130 is observed relatively slowly, and at the position z-118 at the top of the mesh 130, the auxiliary outlet 112b and the outlet 112c are observed. The flow velocity of air is observed rapidly at the eccentric position between), and 100% of test dust (DMT) is exposed to air. As a result, dust separation performance is about 87%.

On the other hand, when the mesh 130 is installed in the eccentric position of the cyclone flow path guide 112 in which the auxiliary outlet 112b and the outlet 112c are formed, the height is parallel to the inlet pipe 110a. At the position (z = 100), the air flow velocity around the mesh 130 is observed relatively fast, and at the position (z = 118) at the top of the mesh 130, the auxiliary outlet 112b and the outlet 112c are observed. Irrespective of the position of the cyclone flow path guide is observed to have a uniform flow rate as a whole, the test dust (DMT) exposed to 100g of air test results, only the first cyclone 110 as described above Even if it passes, the dust separation performance is not only about 90%, but when the first and second cyclones 110 and 120 pass through both, the dust separation performance is 98-99%.

As a result, in the case where the mesh 130 is installed at an eccentric position of the cyclone flow guide 112 in which the auxiliary outlet 112b and the outlet 112c are formed, the auxiliary outlet 112b and the outlet outlet The contaminated air in a state in which the cleaning material is not filtered out of the primary dust container is larger than in the case of (A) in which the mesh 130 is installed at the central position of the cyclone flow path guide 112 in which the 112c is formed. It can be seen that the dust separation performance is superior to the mesh 130 because it does not flow directly into the mesh 130 even though it is immediately re-introduced through the auxiliary outlet 112b and the outlet 112c.

In the above, the present invention has been described in detail by way of examples based on the embodiments of the present invention and the accompanying drawings. However, the scope of the present invention is not limited by the above embodiments and drawings, and the scope of the present invention will be limited only by the contents described in the claims below.

In the vacuum cleaner dust collecting apparatus according to the present invention configured as described above, the cleaning material is filtered while passing through the cyclone flow guide in the vertical direction in the first cyclone, and then the cyclone in the vertical direction inclined in the secondary cyclone. The cleaning material is filtered while passing through the units, but the cyclone units are formed to be inclined with respect to the vertical direction, thereby increasing the cyclone flow path of the air, thereby improving the cleaning performance, and the primary of the first cyclone. By installing the secondary cyclone of the secondary cyclone inside the dust bin, the primary dust bin, which collects a relatively large amount of cleaning material, can be maximized to increase the dust storage capacity and visualize the user. There is an advantage to emptying it.

In addition, the dust collector for the vacuum cleaner according to the present invention, the cyclone flow guide for generating a cyclone flow in the vertical direction is installed inside the primary dust container collecting the cleaning material, the suction air is discharged to the cyclone flow guide Secondary outlets and outlets are formed at the same time as the mesh is installed on the opposite side, the air flows along the cyclone flow guide is divided into the first dust container through the secondary outlets and outlets and discharged, and then re-introduced Increasing the flow length and flow time of the air, and the air re-introduced through the auxiliary outlet and the outlet can pass through the mesh on the opposite side to adjust the flow rate more uniformly to minimize the flow resistance There is an advantage to improve performance.
