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, mesh is installed between the first and second cyclone to catch a relatively large cleaning material such as hair, etc., but by changing the structure of air flow in / out of the primary cyclone flow The present invention relates to a dust collector for a vacuum cleaner that can reduce losses and at the same time improve cleaning performance.

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, such a double cyclone dust collector is cleaned because a hollow cone mesh 6 inside the cylindrical outer cyclone 2 and a hollow cone inner cyclone 4 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. .

In addition, the double cyclone dust collector as described above is formed with a ring-shaped suction flow path (2a) around the inner upper side of the outer cyclone (2) to communicate with the inside of the outer cyclone (2), Since the suction passage 2a is formed inside the outer cyclone 2, the suction passage 2a is relatively narrow and long, so that the suction passage 2a has a large flow resistance even when suction air is sucked along the suction passage 2a. There is a problem in that the suction performance is lowered.

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, 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.

In addition, the double cyclone dust collector as described above is provided with a cylindrical inlet pipe 12a communicating from the outside of the main body 11 to the inner cyclone 12, from the inlet pipe 12a Since a separate flow guide (not shown) is installed inside the inner cyclone 12 to which the inlet pipe 12a is connected to allow the sucked air to flow along the inner wall of the inner cyclone 12, the suction is performed. As air flows along the inlet pipe 12a and hits the flow path guide and flows along the inner wall of the inner cyclone 12a, a rapid flow path change is made, thereby increasing flow loss and decreasing suction performance. There is a problem.

The present invention has been made in order to solve the above problems of the prior art, the cyclone flow path of air by passing through the cyclone in the vertical direction and the inclined vertical cyclone in order to filter the cleaning material twice The purpose is to provide a dust collector for a vacuum cleaner that can increase the.

In addition, the present invention primarily improves the suction performance by reducing the flow resistance of the air flowing into the vertical cyclone, or to improve the flow loss by guiding the flow of air inside the vertical cyclone Its purpose is to provide a dust collector for a cleaner.

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 path guide is formed in such a way that the inlet pipe is connected to a tangential direction of the cyclone flow guide to the inlet port through which air is introduced, and the outlet port for allowing air to flow in and out of the primary dust container is partially cut in the circumferential direction. 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 collecting apparatus according to the present invention, Figures 6a and 6b is a main part in the dust collector shown in Figs. 7A and 7B are side views illustrating an outlet shape of a flow path guide applicable to the dust collector shown in FIGS. 3 to 5.

The dust collector for a 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 as shown in FIG. 3, and the primary cyclone 110. The second cyclone 120 and the air rising from the first cyclone 110 to filter the cleaning material from the air in a vertical cyclone manner is installed inside the secondary cyclone Mesh 130 for filtering a relatively large cleaning material before flowing into the clone 120, and flow path guide means for guiding the air passing through the mesh 130 to the secondary cyclone 120 flows (140) )

Here, the first cyclone 110 is a cyclone flow path guide 112 and the cyclone flow path 112 having a hollow cone shape, as shown in Figures 4 to 5 is built into the cyclone flow path It consists of a primary dust container 114, the cleaning material filtered from the guide 112 is collected, the cyclone flow guide 112 has a space to form a predetermined discharge flow path at the top of the dust at the bottom Is installed to be built in the center of the primary dust container 114 to ensure a space for the stack.

Of course, 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).

Specifically, the inlet pipe 110a which is obliquely communicated with the upper end of the cyclone flow path guide 112 is installed at one side of the primary dust container 114, and the cyclone flow path guide 112 is at the top of one side. An inlet 112a communicating with the inlet pipe 110a is formed and an outlet 112b through which air flows in and out at a predetermined distance in the circumferential direction is formed.

In particular, the inlet pipe (110a) is installed to be connected to the inlet 112a in the tangential direction of the cyclone flow guide 112, as shown in Figure 6a to 6b, the suction inlet 112a A separate suction flow path guide g is installed so that air flows along the inner wall of the cyclone flow path guide 112, and the suction flow path guide g is also formed to be in equilibrium with the inlet pipe 110a so that the suction air The inlet pipe 110a and the suction flow path guide g allow the suction to be directly performed without switching the flow path.

In addition, the outlet 112b is formed so that a portion of the circumferential direction is cut in the cyclone flow path guide 112 so as to be formed in the longitudinal direction of the cyclone flow path guide 112, which is larger than the outlet 112b. It may be configured to further include an outlet guide portion 112 'formed to extend from one end of the outlet 112b to have a radius of curvature to guide the flow of air discharged from the cyclone flow path guide 112, The outflow guide portion 112 ′ may be formed in a flat plate shape.

Furthermore, as described above, the outlet guide portion 112 'is not installed in the outlet 112b, and thus the outlet port has a predetermined width in the circumferential direction, at least one of both ends of the outlet 112b. Inhalation prevention portion (not shown) is formed to be inclined in the opposite direction to the outlet 112b in the air discharged from the cyclone flow path guide 112 is to be sucked back immediately before the cleaning material is filtered It can also be configured to prevent.

At this time, the outlet 112b may be formed such that the width thereof gradually decreases from the top to the bottom of the cyclone flow path guide 112, but in this case, the intake air is mostly the cyclone flow path 112. Since it is difficult to form a helical rotational air flow in the cyclone flow path guide 112 because it exits to the upper portion of the outlet 112b in the reference to the cyclone flow path guide 112 as shown in Figure 7a Outflow 112c is formed so that the circumferential spacing is the same from the upper end to the lower end, or as the circumferential spacing becomes wider from the upper end to the lower end with respect to the cyclone flow guide 112 as shown in FIG. The outlet 112d may be formed.

Next, as shown in FIGS. 4 to 5, the secondary cyclone 120 includes inclined hollow conical cyclone units installed at predetermined intervals in the circumferential direction around the cyclone flow guide 112. 122 and a second dust container 124 installed to communicate with the lower ends of the cyclone units 122 to collect the cleaning material filtered by the cyclone units 122, wherein the cyclone unit The field 122 is preferably configured such that the inlet pipe 110a is not installed at a 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 and at the same time a plurality of through-holes are formed on the side 134 so that a 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 preferably installed to be located on the coaxial inside the cyclone flow path guide (112).

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 has a plurality of communication holes communicating with the upper ends of the cyclone units 122 while a seating hole 142a is formed at the center so that the upper end 132 of the mesh is seated. 142b is formed, and the communication holes 142b are formed with a predetermined interval in the circumferential direction around the seating hole 142a.

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, and at the center corresponding to the mesh 130 on the upper surface. A discharge passage guide 144b protruding downward is formed to guide the air passing through the mesh 130 to flow radially.

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. It is located in the center inside the hole 142b, the diameter of the lower end 148b of the exhaust pipe is formed smaller than the diameter of each communication hole 142b of the horizontal portion to rise from the center of the cyclone units 122 Guide it 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. It is sucked into (112a), and rotates along the inner wall surface of the cyclone flow path guide 112 and flows into the first dust container 114 through the outlet 112b of the cyclone flow path guide.

At this time, the inlet pipe (110a) is installed in the tangential direction of the cyclone flow path guide 112 to the inlet (112a), the suction flow path guide (g) inside the inlet (112a) the inlet pipe ( 110a) is installed in parallel with the suction air is guided in the flow direction of the flow by the inlet pipe 110a and the suction flow guide (g) can not only minimize the flow loss but also improve the suction performance. have.

In addition, since the outlet guide portion 112 ′ is formed to extend from one end of the outlet 112b to the outside of the other end of the outlet 112b, the flow path of air in the cyclone flow path guide 112 can be increased. Therefore, it is easier to form a rotary air stream of the air, and thus, the cleaning material can be easily separated by a cyclone method, thereby improving cleaning performance.

Furthermore, when at least one suction preventing portion of both ends of the outlet 112b is formed, the air discharged through the outlet 112b is prevented from being immediately re-sucked without flowing along the primary dust container 114. The cleaning performance can be improved more.

Next, the air introduced into the primary dust container 114 flows along the primary dust container 114, and cleaning materials such as dust in the air are collected in the primary dust container 114 by its own weight. The air of the primary dust container 114 again flows up through the outlet 112b of the cyclone flow path guide, and ascends, the relatively large cleaning material such as hair is filtered again while passing through the mesh 130.

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 air flows 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.
