Description

FIELD OF THE INVENTION

This document relates to a vacuum cleaner and its device for separating dust.

BACKGROUND OF THE INVENTION

Typically, a vacuum cleaner is a device that uses the suction force generated by the suction motor installed in the main body to suck in air containing dust and filter the dust in the main body.

Such vacuum cleaners can mainly be divided into container-type vacuum cleaners that contain a suction brush located separately from the main body and connected to it, and vertical type vacuum cleaners that contain a suction brush connected to the main body.

A vacuum cleaner of the prior art includes a main body of a vacuum cleaner and a dust separating apparatus installed in a main body of the vacuum cleaner for separating dust from air. A dust separator is typically configured to separate dust using the cyclone principle.

The efficiency of the vacuum cleaner thus made can be determined based on the range of variation of its dust separation efficiency. Therefore, dust separation devices for vacuum cleaners are constantly being improved to increase dust separation efficiency.

In addition, from a user's point of view, dust separators for vacuum cleaners are required that can be easily detached from the main body of the vacuum cleaner and from which dust can be easily removed.

Disclosure of invention

Technical challenge

The purpose of this disclosure is to provide a device for separating dust from a vacuum cleaner with increased dust separation efficiency.

Another objective of the present disclosure is to provide a device for separating dust of a vacuum cleaner containing a dust collecting container with a simplified configuration, to provide easy unloading of dust by a user.

Another objective of the present disclosure is to provide a dust separator for a vacuum cleaner in which a minimum force is required for the user to move the dust collecting container.

Technical solution

In one embodiment, a dust separator for a vacuum cleaner includes a cyclone generating a plurality of swirling air currents; a dust collecting container located on the outside of the cyclone into which dust separated in the cyclone is discharged; and a dust discharge pipe through which the dust separated in the cyclone moves to the dust collecting container

In another embodiment, the dust separator of a vacuum cleaner includes: a dust separating unit forming a dust separating portion and a dust releasing portion directing the discharge of the separated dust; a dust collecting container for containing dust separated in the dust separation unit; a dust exhaust channel for discharging dust and part of the air from the dust discharge section to the dust collecting container and a return air channel for returning air that passes into the dust collecting container to the dust separation unit.

In another embodiment, the device for separating dust of a vacuum cleaner includes a unit for separating dust from air, a dust collecting container into which air passes, which passes into a unit for separating dust, which contains a dust collection unit for containing dust separated from air that passes in a unit for separating dust, and a distribution unit for removing air that passes into the dust collecting container into two or more channels, and distributing air into the unit for separating dust.

Benefits

An advantage in accordance with embodiments of the present disclosure is that since a plurality of inlet openings are formed in the cyclone and a plurality of vortex airflows are generated in the cyclone, the airflow volume is increased and the airflow loss is reduced, thereby improving dust separation efficiency.

In addition, inlet openings are formed on each side of the cyclone, and a dust discharge opening is formed in the center of the cyclone, so that a powerful vortex air flow is formed in the central part of the cyclone, which allows for easy discharge of dust.

In addition, since the dust outlet is formed tangentially to the cyclone, dust can be discharged in the same direction in which it rotates. Thus, it is not only possible to discharge dust with a higher density, but also it is easy to discharge dust with a lower density.

In addition, since the dust collecting container that contains the dust is configured as a separate element with respect to the dust separating device, the user can discharge the dust by disconnecting only the dust collecting container, thereby improving the user convenience when handling the dust collecting container.

In addition, when forming the distribution unit on the dust collecting container, the dust collecting container can be disconnected from the vacuum cleaner and the dust contained in the distribution unit can be easily unloaded, providing easy cleaning of the inside of the distribution unit.

In addition, when forming a channel for returning the air passing into the dust collecting container to the cyclone, the air flow can be continuously maintained in the cyclone, thereby preventing a decrease in the suction force.

An embodiment of the present invention

Below will be given a detailed description of the embodiments in accordance with the present disclosure with reference to the drawings.

FIGS. 1 and 2 are perspective views schematically illustrating the structure of a dust separating apparatus of a vacuum cleaner in accordance with a first embodiment of the present disclosure, and FIG. 3 is a perspective exploded view of the dust separating apparatus of FIGS. 1 and 2.

As shown in FIGS. 1-3, the dust separator 1 of the vacuum cleaner in accordance with the present embodiments includes a dust separator 10 that separates dust from the intake air, a dust collecting container 20 for holding dust separated by the node 10, a suction guide an element 30 that directs the flow of air containing dust to the dust separation unit 10, and a distribution unit 40 for distributing air from the suction guide element 30 to the dust separation unit 10.

In detail, the air drawn in through the suction brush (not shown) passes into the suction guide 30. The suction guide 30 is installed in the vacuum cleaner and is located under the dust container 20. The suction guide 30 includes a distribution unit 40 connected to it.

The dust separation unit 10 separates the dust from the air supplied from the distribution unit 40. The dust separation unit 10 uses a cyclone arrangement to separate dust from the air and includes a cyclone 110 for this purpose.

A pair of inlets 120 are formed (one on each side) in the cyclone 110 for air intake. A pair of inlets 120 may be tangentially formed with respect to the cyclone 110 to create a swirling airflow in the cyclone 110. A pair of inlets 120 forms suction channels for air passing into the cyclone 110.

A pair of inlet pipes 120 is connected to each side of the distribution unit 40. Therefore, air that passes through the suction guide element 30 is discharged to each side in the distribution unit 40, and the exhaust air rises along the corresponding inlet pipes 120 and is sucked into the cyclone 110.

A dust discharge pipe 130 that releases dust separated in the cyclone 110 is formed at the center of the cyclone 110.

Therefore, the dust contained in the air sucked through each inlet 120 on each side of the cyclone 100 is separated from the air by the swirling air flow and moved to the center of the cyclone 110. Then, the dust that passes into the center of the cyclone passes through the exhaust pipe 130 dust and is discharged into a dust container 20.

A dust discharge pipe 130 is formed tangentially to the cyclone 110 to provide easy dust discharge. Thus, the dust separated in the cyclone 110 is discharged tangentially to the cyclone 110, that is, in the same direction in which the dust rotates, providing easy discharge of not only dust with a higher density, but also easy discharge of dust with a lower density from cyclone 110.

Since low-density dust can be easily discharged, low-density dust will accumulate less on the filter element (which will be described below), facilitating the passage of air and increasing the efficiency of dust separation.

In addition, a pair of air outlets 140 is formed, one on each side of the cyclone 110, for discharging air separated from dust in the cyclone 110. Air discharged through the air outlets 140 converges in the intake passage 142 and passes into the main body of the vacuum cleaner (not shown) .

The dust collecting container 20 contains dust separated in the dust collecting unit 10. Since the dust collecting container 20 is installed in the main body of the vacuum cleaner, the dust collecting container 20 is connected to the dust collecting unit 10.

Specifically, when installing the dust collecting container 20 in the main body of the vacuum cleaner, the dust collecting container 20 is located under the dust collecting unit 10. Thus, the dust inlet opening 21 is formed on the upper surface of the dust collecting container 20. In addition, the dust discharge opening 130 extends downward from the cyclone 110.

Therefore, the dust separated in the cyclone 110 moves down along the dust discharge opening 130, and the separated dust can freely pass into the dust collecting container 20.

The cover 22 is connected to the lower part of the dust collecting container 20 for unloading the dust contained therein. The cover 22 can be rotatably connected to the dust collecting container 20 and can be removably connected to it. The method of connecting the cover 22 in the present embodiment is not limited to specific methods.

Thus, the dust collecting container 20 is made in the form of a separate element relative to the dust separation unit 10 and is configured to selectively connect to the dust separation unit 10. Therefore, the user can only disconnect the dust collecting container 20 for discharging dust contained in the dust collecting container 20.

Since a device for separating dust in the dust collecting container 20 is not provided, the design of the dust collecting container 20 is simplified, and the weight of the dust collecting container 20 can be minimized.

By minimizing the weight of the dust container 20, the user can easily carry and manipulate the dust container 20, and since the inner structure of the dust container 20 is simple, dust can be easily discharged to the outside, and the user can easily clean the inside of the dust container 20.

Below will be a more detailed description of the device for separating dust.

Figure 4 depicts a sectional view along the line aa in figure 1, and figure 5 depicts a sectional view along the line bb in figure 1.

As shown in FIGS. 4 and 5, the cyclone 110 includes a housing 111 for creating a vortex air flow and a pair of sides 115, each of which forms one of the two sides of the housing 111. The sides 115 are parallel to each other.

An inlet 120 is respectively formed on each side of the housing 111. Each inlet 120 is formed tangentially to the cyclone 110. Thus, the air drawn in through each inlet 120 forms one of two vortex air flows in the cyclone 110. The vortex air flows circulate along the inner surface of the housing 111.

Thus, when creating a pair of vortex air streams in one space, the volume of the air stream increases, the loss of air flow decreases, and the separation efficiency can be improved.

In addition, when creating a pair of vortex air flows in one space, the cyclone can be made smaller in comparison with a cyclone with one vortex air flow created in one space.

In this description, even if the cyclone 110 is made smaller, the centrifugal force generated in the inlet pipes 120 is greater than in the prior art cyclone, thereby increasing the dust separation efficiency.

In addition, when creating a pair of vortex air flows in one space, the same level of dust separation efficiency can be provided as in a device in which air passes through many dust separation nodes. Thus, additional nodes for separating dust from the air leaving the node for separating dust are not required. However, additional dust separation units may be installed in the present embodiment.

In addition, when creating a pair of vortex airflows, one on each side of the cyclone 110 and when passing vortex airflows to the center, the vortex airflow in the center increases. Therefore, a more powerful vortex airflow is generated in the center of the cyclone 110 than on the sides of the inlet pipes 120.

Thus, when a pair of vortex airflows converges in the center of cyclone 110, the force of the airflow is greater than when a single vortex airflow is created in one space, thus increasing the efficiency of dust separation.

Dust that moves to the center of the cyclone 110 can be discharged through the dust discharge opening 130 to the dust collecting container 20 by a powerful swirling air flow, so that the dust discharge efficiency can be improved.

Hair and other contaminants can easily adhere to the inlet or inner side of the dust exhaust opening 130 by static electricity. However, since in the present embodiment, a powerful swirling air stream is generated in the dust discharge opening 130, hair and other contaminants do not adhere to the dust discharge opening 130 and can be freely discharged into the dust collecting container 20.

An outlet 116 is formed to pass through each side 115 to release air from which dust is separated in the cyclone 110.

In addition, the filter element 150 is connected to each outlet 116 for filtering the exhaust air. In detail, the filter element 150 is configured with a cylindrical fastener 152 attached to the inside of the cyclone 110 and a cone filter 154 extending from the fastener 152 to filter air. In addition, a plurality of holes 156 are formed in the filter 154 for air passage.

Therefore, air separated from dust in the cyclone 110 passes through the plurality of openings 156 and exits the cyclone 110 through the exhaust openings 116.

In this description, the fastener 152 does not have through holes formed therein, so that the air drawn in through the inlet 120 does not immediately exit and is able to circulate uniformly in the cyclone 110.

That is, using the fasteners 152, the intake air circulation can be used to create a uniform vortex air flow in the cyclone 110, thereby increasing the efficiency of dust separation.

The distance (L1) between the pair of filter elements 150 mounted in the cyclone can be made larger than the width (L2) of the dust discharge opening 130.

In detail, the vortex air currents generated in the cyclone 110 converge in the center of the cyclone 110, as described above, and the dust separated from the air by the vortex air stream is discharged through the dust discharge opening 130.

When the distance (L1) between the pair of filter elements 150 is made smaller than the width (L2) of the dust discharge hole 130, contaminants such as hair and tissue paper are not discharged through the dust discharge hole 130 and may adhere to the filter element 150 or get stuck inside openings 156. In this case, air cannot freely pass through the filter element 150, causing a decrease in suction force.

Therefore, in the present embodiments, the distance (L1) between the pair of filter elements 150 is made larger than the width of the dust discharge opening 130, so that contaminants such as hair and tissue paper can be completely discharged through the dust discharge opening 130.

As described above in the present embodiment, air is sucked through the plurality of inlets 120 into the cyclone 110, and air separated from the dust in the cyclone 110 leaves the cyclone 110 through the plurality of exhaust openings 116.

In this way, the air that is sucked into the cyclone 110 through the corresponding inlet pipes 120 exits through the corresponding outlet openings 116, thereby allowing a free exit of air.

When the air thus freely leaves the cyclone 110, the suction force actually increases and a uniform swirl air flow is provided in the cyclone 110.

In addition, even when dust is collected on such a filter element, so that air cannot freely pass, air can exit through another filter element, thereby preventing a sudden decrease in force for air intake.

A hole 112 is formed in the housing 111 of the cyclone 110 to replace and clean the filter element 150. The hole 112 is opened and closed by the cover 160. The sealing element 114 is located at the junction of the hole 112 and the cover 160.

The inner surface of the lid 160 can be made with the same curvature as the inner periphery of the housing 111 by connecting the lid 160 to the housing 111. That is, the inner peripheries of the lid 160 and the housing 111 form a continuous surface. Therefore, changes in swirl air flow due to cover 160 in cyclone 110 can be prevented, and swirl air flow can be maintained continuously.

In addition, since the cover 160 is removably connected to the cyclone 110, the user can remove the cover 160 and easily replace the filter element 150, as well as easily clean the inside of the cyclone 110 and the filter elements 150.

A dust collecting compartment 23 for dust is formed in the dust collecting container 20, and a dust inlet opening 21 is formed in an upper part of the dust collecting container 20. In addition, a sealing member 242 for sealing a contact portion between the dust intake opening 21 and the dust discharge opening 130 is located on dust inlet openings 21. The sealing element 24 may also be located on the hole 130 for the release of dust.

Below will be described the operation of the device for separating dust.

FIGS. 6 and 7 are sectional views illustrating the air flow in the dust separation apparatus according to the first embodiment, where FIG. 6 is a sectional view along line AA in FIG. 1 illustrating the air flow, and FIG. 7 is a cross-sectional view along line BB of FIG. 1 illustrating air flow.

As shown in FIGS. 6 and 7, when the suction power is generated by the vacuum cleaner, dust containing air flows along the suction guide 30. The air passing through the suction guide 30 passes to the distribution unit 40 and is distributed to each inlet 120 by the distribution unit 40 Then, air containing dust passes through each inlet 120 and is sucked in the tangential direction on each side of the cyclone 110.

The intake air rotates along the inner surface of the cyclone 110 and converges in the center of the cyclone 110, and during this process, air and dust are exposed to different centrifugal forces due to their difference in weight, so that separation occurs between them.

The separated dust (indicated by dashed lines) is discharged from the center of the cyclone 110 through the dust outlet 130, and the unloaded dust passes through the dust vents 130 and into the dust collecting container 20.

On the contrary, the air (indicated by solid lines), separated from the dust, is filtered by the filter element 150 and then passes through the exhaust holes 116 and leaves the cyclone 110. The exhaust air passes through the corresponding air outlet 140, converges in the intake channel 142 and passes into the main body of the vacuum cleaner .

FIG. 8 is a perspective view of a dust separation apparatus according to a second embodiment of the present disclosure.

The present embodiment is similar to the first embodiment in all aspects, except for the design of the air passage in the dust separation unit. Therefore, a description will be given only for the distinguishing elements of the present embodiment.

As shown in FIG. 8, the dust separation apparatus according to the present embodiment includes a dust separation unit 210 and a dust collecting unit 210 located on the outside of the dust separation unit 210 for containing dust separated in the separation unit 210 dust.

The dust separation unit 210 includes a cyclone 220 for creating a swirling air stream. The diameter in the center of the cyclone 220 is made larger than the diameter on each side of the cyclone 220. An opening 250 for dust release is formed in the center of the cyclone 220 to discharge the dust separated in the cyclone 220 into the dust collecting container 270.

Fig. 9 is a sectional view taken along line CC in Fig. 8, Fig. 10 is a sectional view taken along line D-D in Fig. 8, and Fig. 11 is a sectional view taken along line EE in Fig. 8.

As shown in FIGS. 9-11, a pair of air inlets 221 is formed, one on each side of the cyclone 220. Therefore, when air is sucked through each air inlet 221, a corresponding pair of vortex air flows is created in the cyclone 220. A pair of vortex air flows created on both sides of the cyclone 220, converges in the center, and the separated dust converges in the center and is discharged into the dust collecting container 270 through the dust outlet 250.

Therefore, the interior of the cyclone 220 can be divided into a dust separation section 222 on each side on which the dust is separated by vortex air flows, and a dust discharge section 224 formed between dust separation sections 222 on which the dust converges and unloads . That is, a dust separating portion 222 is formed on each side of the dust releasing portion 224. In addition, the vertical sectional area of the dust discharge section 224 is larger than the vertical sectional area of the dust separation sections 222.

The interior of the dust discharge pipe 250 includes a channel guide member 260 that directs air passing into the dust collecting container 270 during dust discharge, which passes into the cyclone 220.

That is, the channel guide member 260 divides the interior of the dust discharge pipe 250, so that the dust discharge channel 252 and the return air channel 254 are formed in the dust discharge pipe 250.

In more detail, the channel guide member 260 includes a first guide member 262 formed vertically, a second predetermined curvature guide member 264 extending from the top of the first guide member 262 to the dust discharge portion 224, and a third guide member 266 extending horizontally from the bottom of the first guide element 262.

In more detail, the first guide member 262 is for separating the interior of the dust discharge pipe 250 into two channels, i.e., a dust discharge channel 252 and a return air channel 254.

The second guide member 264 is formed with a curvature corresponding to the curvature of the dust discharge portion 224. Thus, the second guide element 264 is designed to maintain vortex air flow in the area 224 for the release of dust.

In addition, the second guide member 264 provides easy mixing of the air returning to the dust discharge section 224 through the return air channel 254 with the swirling air flow in the dust discharge section 224.

The third guide member 266 includes an opening 267 formed therein to allow air to pass from the dust collecting container 270 and to filter out dust. That is, through the opening 267, dust from the dust collecting container 270 is prevented from passing to the dust discharge section 224 through the return air channel 254. Therefore, the third guide member 266 functions as a filter element that filters the air.

As described above, since the air from the dust collecting container 270 is returned to the cyclone 220 through the return air channel 254, large contaminants such as tissue paper and the attenuation of the weakening force are prevented from sticking to the inside of the dust channel 252 and the air flow is not interrupted and maintains a constant level of suction power.

Specifically, if the dust clogs the dust discharge passage 252, the separated dust cannot be discharged into the dust collecting container 270, and the separated dust is collected in the dust separation unit 10, so that the collected dust prevents the passage of air.

However, when a return air channel 254 is additionally formed, connected to the dust collecting container 270 and cyclone 220, the vacuum created by the vacuum motor installed in the main body of the vacuum cleaner continuously operates in the return air channel 254, and the vacuum discharge dust from the dust exhaust channel 252 into a dust container, so that airflow can be constantly maintained. Furthermore, when the air flow is constantly maintained, a decrease in the suction force is prevented, and the suction force can be maintained constantly.

Below will be described the operation of the device for separating dust in accordance with this embodiment.

Air containing dust passes through a pair of inlets 221 and is sucked into the cyclone in the direction tangent to the cyclone 220.

The intake air circulates in the dust separation sections 222 on each side and converges in the dust discharge section 224, and during this process, air and dust are separated by different centrifugal forces due to their difference in weight.

Separated dust (indicated by dashed lines) circulates in the dust discharge section 224 and is discharged tangentially to the dust discharge passage 252, and the dust discharged passes through the dust discharge passage 252 and enters the dust collecting container 270. Not only the dust, but also a part air also exits through channel 252 to release dust.

In contrast, air (indicated by solid lines), separated from dust, is filtered by a filter element 230 and then passes through an outlet 229 and exits the cyclone 220. The exhaust air passes through an air outlet 240.

The air that enters the dust collecting container 270 passes through the opening 267 and into the return air channel 254 to return to the dust discharge section 224 and mixes with the swirling air flow in the dust discharge section 224.

12 is a cross-sectional view of a dust separation apparatus according to a third embodiment of the present disclosure.

The present embodiment is similar to the second embodiment in all aspects except for the design of the channel guide member. Therefore, only the distinguishing elements of the present embodiment will be described.

As shown in FIG. 12, the return air passage 254 in accordance with the present embodiment includes a first channel guide member 280 formed on the cyclone 220 and a second channel guide member 292 formed in the dust collecting container 290.

In detail, the first channel guide element 280 includes a first guide element 282 formed vertically in the dust discharge pipe 250 and a second guide element 284 with a predetermined curvature extending from the top of the first guide element 282. Since the shapes and functions of the first guide element 282 and the second guide element 284 are similar to the shapes and functions of the first guide element and the second guide element of the second embodiment, their detailed description will be omitted.

The second channel guide element 292 includes a horizontal guide element 293 formed with a predetermined gap from the upper surface of the dust collecting container 270, and a vertical guide element 295 extending upward from one end of the horizontal guide element 293. In addition, the horizontal guide element 293 contains many holes 294 formed therein to filter outgoing air. Therefore, the horizontal guide element 293 functions as a filter element for filtering air.

When connecting the cyclone 220 to the dust collecting container 270, the lower part of the first guide element 282 and the upper part of the vertical guide element 295 are in contact.

As described above, when the second channel guide element 292 is formed in the dust collecting container 290, an air channel can be formed in the dust collecting container 290, and the air channel area is increased by the horizontal guide element 293, allowing easier return of air through the return air channel 254.

13 is a perspective view of a dust separation apparatus according to a fourth embodiment of the present disclosure.

As shown in FIG. 13, the dust separating apparatus 300 of the vacuum cleaner according to the present embodiment includes a dust separating assembly 310 that separates dust from the intake air, a dust collecting container 340 for holding dust separated by the dust separating assembly 310, and a distribution unit 330 that allows air to pass through the dust separator to the dust separator 310.

The dust separation assembly 310 includes a cyclone 320 generating a swirling air stream. The cyclone 320 comprises a pair of inlet pipes 321 formed therein for suctioning air. The inlet nozzles 321 are respectively connected to the distribution unit 330.

The distribution unit 330 provides for the separation of the air leaving the dust container 340 into two channels.

Fig. 14 is a sectional view along the line F-F in Fig. 13, and Fig. 15 is a sectional view along the line G-G in Fig. 13.

As shown in FIGS. 14 and 15, the dust collecting container 340 includes a dust collecting housing 350 defining an appearance of the dust collecting container 340 and a lid 360 connected to the upper part of the dust collecting housing 350.

In detail, the dust collecting case 350 includes a first wall 351 that is cylindrical, a second wall 352 surrounding a portion of the first wall 351, and a third wall 353 forming the lower surface of the dust collecting case 350. The second wall 352 also has an approximately cylindrical shape. The radius of the second wall 352 is greater than the radius of the first wall 351.

Therefore, the dust collecting case 350 includes a first space (A) formed inside the first wall 351 and a second space (B) formed between the first wall 351 and the second wall 352.

The lower part of the first space (A) serves as the first dust collecting compartment 357. The second space (B) serves as the second dust collecting compartment 358. The cover 360 forms the upper surface of the second dust collecting compartment 358. The second dust collecting compartment 358 also contains dust separated by the dust separation unit 310 .

The first wall 351 comprises an inlet 354 formed therein for suction of dust containing air. The first dust collecting compartment 357 comprises a separation guide element 380 located therein for separating soft paper and other large contaminants from the air.

Therefore, air containing dust that passes through the inlet 354 into the space formed by the first wall 351 is subjected to a dust separation process by the separation guide element 380 in the space formed by the first wall 351. That is, air and dust sucked through the inlet 354 pass down and air and dust separate when passing down.

Therefore, the upper part of the first wall 351 forms a separation chamber 356, in which dust is separated from the air. That is, the upper part of the first space (A) serves as a chamber 356 for separating dust, and the lower part of the first space (A) performs the function of a first dust collecting compartment 357.

Although the dust separation chamber 356 has been described as being functionally separated from the first dust collecting compartment 357 forming the first space (A) for the purpose of simplifying the description, the dust separation chamber 356 and the first dust collecting compartment 357 are not actually structurally separated. Thus, for example, when a large amount of dust is accumulated in the first space (A), the first dust collecting compartment 357 can be formed in the form of the entire first space (A).

In addition, dust separated in the dust separation chamber 356 is collected in the first dust collecting compartment 357, and air is passed to the separation guide element 380.

The spacer guide member 380 is connected to the bottom of the cover 360. The cap 360 is connected to the dust collecting case 350, and the spacer guide member 380 is inserted into the interior defined by the first wall 351.

The separation guide element 380 is made in a cylindrical shape with holes 382 and 383 formed respectively on the upper and lower surfaces. Therefore, an exhaust channel 385 through which air exits is formed in the spacer guide member 380.

Air that passes through the exhaust channel 385 passes through the exhaust hole 362 and passes into the distribution unit 330.

The lower end of the separation guide element 380 is located at a predetermined distance from the bottom wall 353. A plurality of through holes 384 are formed in the lower part of the separation guide element 380 to allow air to pass into the exhaust channel 385.

Therefore, air from the first dust collecting compartment 357 passes into the opening 383 through a gap (G) between the separation guide element 380 and the bottom wall 353 and passes into the exhaust duct 385. Air from the first dust collecting compartment 357 can pass into the exhaust duct 385 through the through holes 384.

The dust separated in the dust separation unit 310 extends to the second dust collecting section 358. A dust inlet opening 364 is formed in the lid 360 to allow dust to pass through the dust separation unit 310.

A pressing member 370 for pressing dust contained in the second dust collecting compartment 358 is installed in the second dust collecting compartment 358.

In detail, the pressing member 370 includes a hollow rotating shaft 372 and a pressing plate 374 extending from the rotating shaft 372. The mounting shaft 355 is configured to extend upwardly on the bottom wall 353 and connected to the rotating shaft 372. A portion of the rotating shaft 372 is inserted into the mounting shaft 355.

The drive gear 390 is connected to the rotary shaft 372 to transmit driving force to the rotary shaft 372. The drive gear 390 is connected to the lower end of the rotary shaft 372 from the outside of the dust collecting case 350. When the drive gear and the rotary shaft 372 are connected, the fastener 376 is secured to the drive gear 390 and rotating shaft 372.

The pinion gear 390 is connected to the pinion gear 392, and the pinion gear 392 is connected to the shaft of the compression motor 394. The pinion gear 392 and the compression motor 394, although not shown, can be mounted in the main body of the vacuum cleaner. When installing the dust collecting container 340 in the main body of the vacuum cleaner, the drive gear 390 and the drive gear 392 engage.

Therefore, as the compression motor 394 rotates, the pinion gear 392 connected to the compression motor 394 rotates. As the pinion gear 392 rotates, the pinion gear 390 engaged with the pinion gear 392 also rotates. The pressing member 370 connected to the drive gear 390 rotates and compresses the dust contained in the second dust collecting compartment 358. The compression motor 394 used may be an electric motor that can rotate in two directions to rotate the pressing member 370 in one of two directions.

Below will be described the operation of the device for separating dust.

Dust from the surface to be cleaned is first sucked in with air into the chamber 356 to separate the dust in the space formed by the first wall 351 of the dust collecting case 350. Air containing dust moves in a spiral flow direction along the inner surface of the dust separation chamber 356 and moves downward. Air and fine dust that move downward pass through the through holes 384 and the hole 383 and pass into the exhaust channel 385.

In contrast, larger contaminants, such as soft paper, are either wound around the separation guide element 380, or stuck at the lower end of the separation guide element 380 while moving down.

Air and fine dust that pass into the exhaust channel 385 pass through the exhaust port 362 and pass into the distribution unit 330. Air and fine dust that move into the distribution unit 330 pass into the cyclone 320 through the corresponding inlet openings 321.

The air that flows into the cyclone 320 spirals along the inner surface of the cyclone 320 and moves to the center of the cyclone 320. During this process, different centrifugal forces act on the air and fine dust, due to their different weights, and thus separate.

The separated dust is discharged from the center of the cyclone 320 through the dust outlet 323. Dust discharged through the dust exhaust port 323 passes through the dust inlet port 364 and passes into the second dust collecting compartment 358 of the dust collecting container 340.

According to the present embodiment, contaminants, such as soft paper, are separated from the air in the dust collecting container 340, and the separated polluting particles are collected in the first dust collecting section 357 of the dust collecting container 340.

After the second dust separation step is performed in the dust separation unit 310, the dust separated in the dust separation unit 310 is collected in the second dust collecting section 358 of the dust collecting container 340.

In accordance with the present embodiment, larger contaminants, such as soft paper, are separated in a first step in a dust collecting container to prevent large contaminants from passing into the dust collecting unit 310. Since large pollutants do not pass into the dust separation unit 310, attenuation of the air flow in the dust separation unit 310 by large pollutants can be prevented.

In addition, since large contaminants, such as soft paper, accumulate in the dust collecting container 340, accumulated contaminants can be easily removed.

The present embodiment is similar to the fourth embodiment in all aspects, except for the design of the separation guide element. Therefore, only the distinguishing elements of the present embodiment will be described.

As shown in FIG. 16, a plurality of gripping ribs 402 are formed at the bottom of the spacer guide member 400 in the present embodiment. The gripping ribs 402 extend down to the lower peripheral portion of the spacer guide member 400 and are spaced apart. The lower ends of the gripping ribs 402 are pressed against the lower wall 353 of the dust collecting case 350.

Through separated capture ribs 402, inlet openings 404 are formed between respective capture ribs 402 through which air from the first dust collecting compartment 357 passes into the separation guide element 400. In addition, auxiliary intake holes 406 are formed at the bottom of the separation guide element 400 to allow unhindered passage of air. into the separation guide element 400.

In another aspect, the lower surface of the spacer guide member 400 may be pressed against the bottom wall 353 of the dust collecting case 350, and inlets 404 may be formed at the bottom of the spacer guide member 400, so that the ribs 402 may be formed by the inlets 404.

A guide member 561 on the bottom surface may be connected to the third partition 552 by means of a press fitting, and a guide member 562 on the side surface may be connected to the cover 550 by means of a press fitting. A guide member 561 on the bottom surface, as shown in FIG. 18, is formed in a semicircular shape.

When connecting the element 560 for directing the flow with the cover 550, an air channel 555 is formed using the lower surface of the cover 550, the element 560 for directing the flow and the third partition 552.

A through hole 564 is formed in the guide member 561 on the bottom surface to allow air passing into the separation guide element 570 to pass into the air channel 555. The separation guide element 570 is connected around the through hole 564.

A pair of exhaust openings 553 and 554 are formed in the cover 550 for venting air from the air passage 555 and passing through the corresponding inlet openings 321 of the cyclone 320 in the fourth embodiment. That is, the present embodiment, in contrast to the fourth embodiment, comprises a distribution unit in the dust collecting container 500. Outlets 553 and 554 function as distribution channels.

As shown in FIG. 20, the dust separating device 600 in accordance with the present embodiment includes a main separation unit 610 for separating dust from the intake air, a dust collecting container 630 for holding dust separated by the main separation unit 610, and a suction guide member 615 for directing the flow of air containing dust into the dust container 630.

Air passing through the suction guide element 615 passes through the dust collecting container and then passes into the main separation unit 610.

The main separation unit 610 includes a cyclone 620 for creating a swirling air flow. A pair of inlets 622 is formed, one on each side of the cyclone 620, for sucking air from the dust collecting container 630. A dust discharge pipe 624 is formed in the center of the cyclone 620 to discharge dust separated in the cyclone 620.

FIG. 21 is a perspective view of a dust collecting container according to a seventh embodiment; FIG. 22 is a sectional view taken along line J-J in FIG. 21; and FIG. 23 is a sectional view taken along line KK in FIG. 21.

As shown in FIGS. 21-23, the dust collecting container 630 in accordance with the present embodiment includes a dust collecting housing 640 and a cover 690 connected to the upper part of the dust collecting housing 640.

In detail, the dust collecting case 640 includes a first wall 641 defining a general appearance of the dust collecting case 640 and a second wall 642 dividing the interior space formed by the first wall 641 into two spaces.

A dust collecting compartment 644 for containing dust separated by a main separation unit 610 is formed on one side (left side in FIG. 22) of a second wall 642, and a distribution unit 670 for distributing air passing into the dust collecting case 640 to the main separation unit 610 is formed on the other side (right side in FIG. 22).

A pair of pressing members is installed in the dust collecting chamber 644 for pressing dust contained in the dust collecting chamber 644. In detail, the pressing member includes a stationary member 653 attached to the inner periphery of the dust collecting chamber 644, and a rotating member 650 rotatably mounted in the dust collecting chamber 644 .

The fixed element 653 extends upward to a predetermined height from the bottom surface of the dust collecting compartment 644. A through hole 656 is formed on the second wall 642 through which the rotary shaft 652 of the rotary element 650 passes. The guide rib 654 is configured to protrude on the second wall 642 to direct rotation of the rotary shaft 652. As the rotating shaft 652 passes through the through hole 656, the rotating shaft is pressed against the guide rib 654.

A portion of the rotary shaft 652 passes through the through hole 656 and is located in the distribution unit 670 and is connected to the shaft 662 of the drive gear 660 passing through the first wall 641 forming the distribution unit 670. That is, the first wall 641 forming the distribution unit 270 includes a through hole 658 formed in it, through which passes the shaft 662 of the drive gear 660.

Drive gear 660 is transmitted driving force from a drive gear (not shown) located in the main body of the vacuum cleaner. The drive gear can be connected to a compression motor installed in the main body of the vacuum cleaner. Part of the drive gear can be opened to the outside of the main body of the vacuum cleaner. Thus, when installing the dust collecting container 630 in the main body of the vacuum cleaner, the drive gear 660 and the drive gear are engaged.

The distribution unit 670 is formed by a part of the first wall 641 and the second wall 642.

Distribution unit 670 includes a main channel 673 into which air exits from the suction guide member 615 and a pair of distribution channels 674 and 676 branching off from the main channel 673. Although one pair of distribution channels is described in the present embodiment, there is no limitation for the number of distribution channels that can be formed. However, the number of formed distribution channels may be equal to the number of inlets 622 of the main separation unit 610.

The distribution unit 670 includes an air inlet 673 through which air passes into the main channel 673. The partition 672 is formed in the distribution unit 670 to separate the distribution channels 674 and 676.

An auxiliary separation unit 680 is connected to the distribution unit 670 by inserting a part into the distribution unit 670 to separate large contaminants, such as soft paper, from the air.

In detail, the auxiliary separation unit 680 includes a dust collector 683 for separating large contaminants, such as soft paper, from air passing into the main channel 673. A hole 674 is formed on the distribution unit 670 for inserting the dust collector 683 into the distribution unit 670 when the auxiliary separation is connected node 680.

The auxiliary separation unit 680 also includes a door 681 for opening and closing the opening 684. One side of the door 681 is rotatably connected by a hinge 682 to the distribution unit 670, and the other side is removably connected to the distribution unit 670 using the fixing hook 688 .

The dust collector 683 extends to the outside of the distribution unit 670 by turning the door 681, which opens the hole 674, and is located in the main channel 673 when closing the hole 674 with the door 681.

Thus, in the present embodiment, by turning the door 681 to extend the dust collector 683 to the outside of the distribution unit 670, dust captured in the dust collector 683 can be easily removed.

In addition, when the dust collector 683 is located in the main channel 673, it is located at a distance from the first wall 641 and the second wall 642.

The dust collector 683 includes a pair of guide elements 684 located at a predetermined distance from each other, a connecting element 685 connecting the ends of the guide elements 684 and located adjacent to the second wall 642, and a gripping element 686 connecting the upper parts of the pair of guide elements 684.

As shown in FIG. 22, the width (W) of the gripping member 686 is less than the width of the guide elements 684. The gripping member 686 is located at a distance from the connecting member 685. Thus, a space 687 is formed between the gripping member 686 and the connecting member 685 for air passage.

A portion of the dust-containing air that passes into the main channel 682 passes through the space 687, and large contaminants, such as soft paper, are captured by the capture element 686 as air passes through the space 687.

A plurality of through holes 685a through which air can pass are formed in the upper part of the connecting element 685. Thus, the upper part of the connecting element 685 is formed in a wave-like manner through the through holes 685a.

The cover 690 is connected to the upper part of the dust collecting case 640. When connecting the cover 690 to the upper part of the dust collecting case 640, it also covers the side of the dust collecting compartment 644 and the side of the distribution unit 670.

A dust inlet opening 682 for allowing air to pass through the dust exhaust opening 624 to the dust collecting compartment 644 is formed in the lid 690. In addition, air outlets 694 and 695 are formed in the air exhaust lid 690 located in the respective distribution channels 674 and 676, from distribution unit 670.

Below will be described the operation of the device for separating dust.

Air containing dust flows along the suction guide element 615. Air passing through the suction guide element 615 passes through the air inlet 673 and enters the main channel 682 of the distribution unit 670. Air containing dust that passes into the main channel 682 is discharged and passes into the respective distribution channels 674 and 676.

During the removal of dust-containing air from the main channel 672 to the distribution channels 674 and 676, large contaminants, such as soft paper, are captured by the pickup member 686.

The air that flows into the respective distribution channels 674 and 676 passes through the air outlets 694 and 695 and passes into the inlets 622 of the main separation unit 610. The air that passes into the main separation unit 610 contains hair and fine dust particles.

Air that flows through the respective inlets 622 and is sucked into the cyclone 620 undergoes an additional dust separation process. The separated dust is discharged through the dust outlet 624 from the cyclone 620, and the unloaded dust passes through the dust outlet 624 and passes into the dust collecting compartment 214 of the dust collecting container 630 through the dust inlet 692.

24 is a perspective view illustrating an auxiliary separation unit advanced from a dust collecting container in accordance with a seventh embodiment.

As shown in FIG. 24, to remove dust trapped by the gripping member 686, the auxiliary separation unit 680 extends from below. Then, the auxiliary separation unit 680 is rotated around the hinge 682, and the dust collector 683 with the pick-up element 686 formed thereon is pulled out onto the outside of the distribution unit 670. As for large contaminants, such as soft paper, captured by the pick-up element 686, the pollutants are pulled together with a dust collector 683. Therefore, in a state in which the dispensing assembly 670 is pulled outward, the user can easily remove soft paper, etc. from the dust collector 683.

25 is a perspective view of a dust separation apparatus according to an eighth embodiment of the present disclosure.

The present embodiment is similar to the seventh embodiment in all aspects, except for differences in the design of the dust collecting container. Therefore, only the distinguishing elements of the present embodiment will be described.

In detail, the partition 770 has a U-shaped horizontal section. The partition 770 includes a pair of protruding parts 771 and 772 extending from the inner surface (or from the second wall 732) of the distribution unit 760, and a connecting element 775 connecting the ends of the pair of protruding parts 771 and 772.

The connecting element 775 is located at a distance from the lower surface 760a of the distribution unit 760. The connecting element 775 and a pair of protruding parts 771 and 772 are separated from the inner periphery of the distribution unit 760 or the first wall 731 forming the distribution unit 760. Distribution channels 777 and 778 are formed, one channel on each side of a pair of protruding parts 771 and 772.

Air from the respective distribution channels 777 and 778 passes through the air outlets 784 and 786 and passes into the inlet 722 of the dust separation unit 710.

Through holes 773 and 774 are formed in the protruding parts 771 and 772, through which part of the air from the separation chamber 776 can be discharged into the distribution channels 777 and 778. The through holes 773 and 774 are located next to the cover 780 when the cover 780 is connected to the dust collecting case 740. That there are through holes 773 and 774 located adjacent to the air outlet openings 784 and 786, respectively.

When, thus, through holes 773 and 774 are formed in the protruding parts 771 and 772, part of the air from the separation chamber 776 is discharged into the distribution channels 777 and 778 to prevent the dropping of large polluting particles separated in the separation chamber 776 and to prevent the movement of large polluting particles, which descended into the air outlets 784 and 786.

The capture element 788 is formed on the cover 780 to capture large contaminants, such as soft paper, from the air that passes into the separation chamber 776. The capture element 788 extends a predetermined distance from the bottom surface of the cover 780. When the cover 780 is connected to the dust collecting case 740, element 788 is located in the space between the pair of protruding parts 771 and 772.

30 is a side elevational sectional view illustrating a distribution unit connected to a suction guide member in accordance with an eighth embodiment.

As shown in FIG. 30, the suction guide element 715 is connected to the lower part of the distribution unit 760. The suction guide element 715 is made in a curved shape. Due to the curvature of the suction guide element, the suction guide element 715, when viewed from a vertical section, includes a section 716 with a larger curvature and a section 717 with a lower curvature.

A guide rib 718 is formed in a portion 716 with a greater curvature for directing the flow of light contaminants, such as soft paper. The guide rib 718 is formed with a predetermined length in the longitudinal direction of the suction guide member 715. The guide rib 718 extends from a portion with a greater curvature to a portion with a lower curvature of the suction guide member 715. The guide rib 718 may be singular or plural.

As for the dust channel of the suction guide member 715, heavier dust from dust moving through the suction guide member 715 moves along the greater curvature portion 716 due to inertia.
