BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vacuum cleaner and a dust collecting apparatus, and more particularly, to a vacuum cleaner and a dust collecting apparatus, in which dust separation performance is improved and backflow of dust collected is prevented.

In general, a vacuum cleaner is a device that sucks air containing dust by using a vacuum pressure generated by a suction motor mounted inside the main body, and then filters the dust inside the main body.

Such a vacuum cleaner may be distinguished by a canister method in which a nozzle part which sucks air containing dust on the surface to be cleaned is provided separately from the main body and connected by a connecting pipe, and an upright method in which the nozzle part is integrally formed with the main body.

On the other hand, the dust collecting device mounted on the cyclone vacuum cleaner is a device using the cyclone principle, so that the dust contained in the sucked air is rotated together to be collected separately from the air, the dust separated air is discharged to the outside to be.

The conventional cyclone dust collector includes a cylindrical cyclone body, a suction pipe through which air containing dust is sucked, a discharge hole through which air introduced into the cyclone body is discharged, and a filter for filtering the dust. . At this time, the inner space of the cyclone body is partitioned by the partition wall and the dust separation unit and the dust storage unit is formed, the partition wall is formed with a dust discharge hole for dust discharge to the dust storage unit.

The operation of the cyclone dust collecting device having the above configuration will be described briefly. When the suction motor is driven, dust containing air is sucked into the cyclone body. At this time, the air containing the dust is sucked in a tangential direction with respect to the cyclone body through the suction pipe of the cyclone body, and then descends while turning along the inner wall surface of the cyclone body. In this process, air and dust are separated from each other under different centrifugal forces due to their weight differences. In addition, the relatively heavy dust flows down the inner wall of the cyclone body while being subjected to centrifugal force and is discharged into the dust storage unit, which is the bottom of the cyclone body, through the dust discharge hole.

By the way, according to the conventional dust collector, the following problems arise.

First, in the case of the conventional dust collector, the dust is formed in the partition wall, the separated dust is configured to fall by its own weight to the dust storage portion, so that the relatively dense dust is relatively well downward through the dust discharge hole Although falling, dust having a relatively low density does not fall through the dust discharge hole, and the problem remains that the dust remains intact.

That is, since the flow direction of the dust after the separation and the flow direction of the dust in the separation process is formed differently, the separated dust does not completely fall into the dust storage unit.

In addition, since the dust having a small density remains in the dust separation unit, dust accumulates on the surface of the filter provided in the dust separation unit, and thus the air is not smoothly flown and the dust is not smoothly removed. .

Second, according to the conventional dust collector, the dust discharge hole is formed in the partition wall, and the dust separated through the dust discharge hole is configured to fall, so that the dust stored in the dust storage unit is scattered by the rotating airflow during the dust separation process. Floating, there is a problem to flow back to the dust separator through the dust discharge hole.

In addition, such a reversed dust causes a problem that the dust separation performance of the dust separation unit is degraded.

The present invention has been proposed to solve the above problems, and an object of the present invention is to propose a vacuum cleaner and a dust collecting apparatus for allowing the dust separated from the dust separation unit to easily fall into the dust storage unit.

It is also an object of the present invention to propose a vacuum cleaner and a dust collecting unit for preventing a phenomenon in which dust stored in the dust storage unit flows back to the dust separation unit.

In addition, an object of the present invention is to propose a vacuum cleaner and a dust collecting apparatus for facilitating the coupling of the dust separation unit and the dust collecting body in which the dust storage unit is formed.

Hereinafter, the configuration of the dust collecting apparatus according to the present invention will be described in detail.

4 is an exploded perspective view of the dust collector.

Referring to FIG. 4, the dust collecting apparatus 200 according to the present invention includes a dust collecting body 210 forming an outer shape, and a dust collecting body that is selectively accommodated in the dust collecting body 210 and separates dust from sucked air. 1 includes a dust separator 230 provided with the cyclone unit 231, and a cover member 270 for selectively opening and closing the upper side of the dust collecting body 210.

In detail, the dust collecting body 210 is formed in a substantially cylindrical shape, and a dust storage unit in which the separated dust is stored is formed therein.

The dust storage unit includes a first dust storage unit 214 in which dust separated from the first cyclone unit 231 is stored, and a second dust in which dust separated from the second cyclone unit 300 is stored. Dust storage unit 216 is included.

Here, the dust collecting body 210 is connected to the first wall 211 forming the first dust storage unit 214 and the second dust storage unit 216 in relation to the first wall 211. A second wall 212 that forms is included. That is, the second wall 212 is formed to surround a predetermined portion of the first wall 211.

Therefore, the second dust storage unit 216 is formed outside the first dust storage unit 214.

As such, as the second dust storage unit 216 is provided outside the first dust storage unit 214, the size of the first dust storage unit 214 may be maximized, such that the first dust There is an advantage that the dust collecting capacity of the storage unit 214 is maximized.

In addition, the first wall 211 is formed with a step 219 supporting the lower end of the dust separation unit 230 accommodated therein. Accordingly, the dust collecting body 210 is divided into an accommodation part 213 in which the dust separation part 230 is accommodated, and the first dust storage part 214, based on the step 219. 213 has a larger diameter than the first dust storage unit 214.

At least the strength reinforcing ribs 217 are formed in the second dust storage unit 214 so that the strength of the second wall 212 forming the second dust storage unit 214 is improved. In this case, the strength reinforcing rib 217 is integrally formed with the first wall 211 and the second wall 212. Accordingly, the second dust storage unit 214 is divided into at least two spaces by the strength reinforcing rib 217.

In detail, the first guide part 234 extends laterally from the first cyclone part 231. The first guide part 234 is rounded in cross section so that a guide action can be performed smoothly.

Since the first guide part 234 protrudes from the first cyclone part 234, the second guide part 215 has the dust collecting body 210 to accommodate the first guide part 234. It is formed by recessing outward from the first wall 211. At this time, the second guide part 215 is formed to be recessed toward the second dust storage part 216. That is, the second guide portion 215 is recessed from the first wall 211 toward the second wall 212.

As the second guide part 215 is recessed and molded toward the second dust storage part 216, the second guide part 215 is not exposed to the outside, thereby preventing aesthetics from being impaired.

Here, since the second dust storage unit 216 stores relatively small fine dust, the second dust storage unit may be formed by recessing the second guide unit 215 toward the second dust storage unit 216. The dust storage space of 216 can be secured.

Therefore, the user can easily accommodate the dust separation unit 230 in the dust collecting body 210 by the guide portion (215, 234). As well as. As the accommodation of the dust removing unit 230 is guided, the coupling of the cover member 270 to which the dust separating unit 230 is coupled and the dust collecting body 210 may be guided.

In addition, the dust separation unit 230 is fastened to the lower side of the cover member 270 to be separated together with the cover member 270 when the dust stored in the dust collecting body 210 is discharged. It is fixed.

On the other hand, the cover member 270 is detachably coupled to the upper side of the dust collecting body 210. That is, the cover member 270 opens and closes the first dust storage unit 214 and the second dust storage unit 216 at the same time.

Therefore, in order to discharge the dust stored in the first dust storage unit 214 and the second dust storage unit 216 to the outside, the user has to cover the cover member 270 is fixed to the dust separation unit 230 When separated from the dust collecting body 210, the upper end of the dust collecting body 210 is completely opened. And, when the user flips the dust collecting body 210, the dust is easily discharged.

At this time, in order to empty the dust collecting body 210, the user separates the cover member 270 from the dust collecting body 210 in a trash can or outdoors, thereby preventing recontamination of the room.

In addition, a filter member 280 for filtering air discharged from the first cyclone unit 231 is coupled to the lower side of the cover member 270.

Hereinafter, the structure and function of each component of the dust collecting device 200 will be described in more detail.

5 is a bottom perspective view of the cover member according to the present invention, and FIG. 6 is a perspective view of the filter member according to the present invention.

5 and 6, a discharge hole 274 through which dust separated from the first cyclone part 231 is discharged is formed through the center portion of the bottom surface of the cover member 270. In addition, an upper end of the filter member 280 having a plurality of through holes 282 having a predetermined size is coupled to the discharge hole 274.

Therefore, the air that has undergone the first dust separation process in the first cyclone portion 231 is discharged to the discharge hole 274 through the filter member 280.

In addition, a plurality of fastening ends 275 are formed around the discharge hole 274 to couple the filter member 280.

In detail, the fastening end 275 includes a first fastening end 275a and a second fastening end 275b having a smaller size than the first fastening end 275a. As the size of each fastening end is formed differently, the coupling position of the filter member 280 is guided so that the filter member 280 can be coupled to the correct position of the cover member 270.

In addition, a plurality of coupling guides 276 for guiding the coupling of the dust separator 230 are formed at a predetermined interval below the cover member 270. At this time, when the dust separation unit 230 is coupled to the cover member 270, the coupling guide 276 surrounds a part of the upper end of the first cyclone unit 231.

In addition, a fastening part 277 for fastening the fastening member is formed on the side of the gap of each of the coupling guides 276.

On the other hand, the filter member 280 includes a cylindrical filter body 281 with an open upper side. A plurality of through holes 282 are formed on an outer circumferential surface of the filter body 281, and a guide rib 284 extending in a horizontal direction on the upper side of the filter body 281 to guide the fastening of the filter member 280. Is formed.

Here, the guide rib 284 is in close contact with the bottom surface of the cover member 270 when the filter member 280 is fastened to the cover member 270 is the air discharged through the discharge hole 274 is It also serves to prevent leakage to the first cyclone portion 231 through the contact portion between the filter member 280 and the cover member 270.

The guide ribs 284 are formed with a plurality of fastening ribs for fastening with the fastening ends 275a and 275b.

In detail, the fastening rib includes a first fastening rib 285a extending in the horizontal direction from the guide rib 284 and a second fastening rib 285b formed smaller than the first fastening rib 285a.

In this case, the fastening ends 275a and 275b have a vertical cross section having a “┗” shape in order to rotate the fastening ribs 285a and 285b. Therefore, when the fastening ribs 285a and 285b are rotated by a predetermined distance in the clockwise direction when the fastening ribs 285a and 285b are aligned with the fastening ends 275a and 275b, the filter member 280 is completely coupled to the cover member 270.

In addition, the bottom surface of the cover member 270 has a plurality of dust to be introduced into the cover member 270 through the dust inlet (refer to 272 of FIG. 3) to the second dust storage unit 216 A dust outlet 273 is formed. Here, the second dust storage unit 216 is divided into at least two spaces by the strength reinforcing rib 217, it is preferable that at least two dust outlets 273 are formed.

7 and 8 are an external perspective view of the dust separation unit according to the present invention, Figure 9 is a plan view of the dust separation unit.

7 to 9, the dust separation unit 230 extends to the side of the first cyclone portion 231 and the first cyclone portion 231 having a cylindrical shape, the upper and lower sides of which are opened. A bottom portion 232 constituting the bottom is included.

A compartment for shielding the first cyclone part 231 from the lower side of the dust separator 230 so as to partition the first cyclone part 231 and the first dust storage part 214. The plate 250 is rotatably coupled.

In detail, the first cyclone unit 230 is formed with a suction unit 233 to allow the air to be sucked into the interior. The suction part 233 is formed at a position corresponding to the first air inlet 218 formed in the dust collecting body 210.

Therefore, when the dust separator 230 is accommodated in the dust collecting body 210, the suction part 233 is aligned with the first air inlet 218 to communicate with the first air inlet 218.

In this case, the suction part 233 is formed in a tangential direction to the first cyclone part 231 so that the air sucked in may spirally flow along the inner circumferential surface of the first cyclone part 231.

The bottom portion 232 is formed to extend in the horizontal direction from the first cyclone portion 231. At this time, the end of the bottom portion 232 is rounded to a predetermined curvature, the imaginary line extending the curvature of the end of the bottom portion 232 is circular.

Hereinafter, the virtual line which extended the curvature of the edge part of the bottom part 232 is called "the virtual circle of the bottom part 232."

In addition, the diameter of the virtual circle of the bottom portion 232 is formed to correspond to the diameter of the receiving portion 213 of the dust collecting body (210). Here, since the bottom portion 232 is formed to extend to the side of the first cyclone portion 232, the diameter of the first cyclone portion 231 is easily formed smaller than the diameter of the bottom portion 232 You can guess.

As shown in FIG. 9, the center C2 of the first cyclone portion 231 is eccentrically formed with respect to the center C1 of the virtual circle of the bottom portion 232. The one cyclone portion 231 is formed at a position having a single common tangent with the virtual circle of the bottom portion 232. The reason for this is to ensure the width of the dust guide flow path 240 to be described below to smoothly flow the dust.

On the side of the first cyclone portion 231, a first guide portion 234 for guiding the dust separator 230 is formed. Since the structure of the first guide part 234 is as described above, a detailed description thereof will be omitted.

In addition, a plurality of fastening ribs 237 are formed at an upper end of the first cyclone part 231 to allow the dust separating part 230 to be fastened to the cover member 270. ) Is formed with a fastening hole 238 for fastening the fastening member.

At this time, when the dust separation unit 230 is coupled to the cover member 270, the fastening ribs 237 is located in the gap formed between each of the coupling guide 276.

On the other hand, the dust separation unit 230 is provided with a dust guide flow path 240 for guiding the dust separated by the first cyclone portion 231 in the tangential direction to flow downward after flowing therein do. In another aspect, the dust guide flow path 240 serves to guide the separated dust to be discharged in the tangential direction from the first cyclone portion 231.

In detail, the inlet 242 of the dust guide flow path 240 is formed at the lower side of the first cyclone portion 231. In addition, an outlet of the dust guide flow path 240 is formed in the partition plate 250.

That is, the partition plate 250 is formed in a shape corresponding to the virtual circle of the bottom portion 232 to shield the virtual circle of the bottom portion 232, the position corresponding to the end of the dust guide flow path 240 An opening 252 is formed in the upper portion 252, so that the dust introduced into the dust guide flow path 240 may fall into the first dust storage unit 214.

In addition, in order to facilitate the inflow and discharge of dust, it is preferable that the area of the inlet 242 and the opening 252 is formed to be substantially the same.

In addition, a guide rib 245 is formed at the inlet 242 side of the dust guide flow path 240 to guide the separated foreign matter to flow in the tangential direction of the first cyclone part 231. The guide rib 245 extends outward from the first cyclone portion 231 in a tangential direction, and an end thereof is formed to reach the outer circumference of the bottom portion 232.

In addition, the upper surface portion 246 forming the dust guide flow path 240 is formed perpendicular to the outside of the outer wall 234, the opening 252 side of the guide rib 245 on the inlet 242 side It is extended to the bottom portion 232 of the.

In addition, the width of the dust guide flow path 240 is equal to the width of the upper surface portion 246. And, as described above, as the first cyclone portion 231 is eccentrically formed with respect to the virtual circle of the bottom portion 232, the width of the dust guide flow path 240 is secured to a predetermined size or more, thereby increasing the volume. It is possible for large dust to flow into the dust guide flow path 240.

In addition, the upper surface portion 246 is formed to be bent downward toward the opening 252 side from the inlet 242 side to facilitate the smooth flow of dust.

Therefore, the upper surface portion 246 is bent downwardly formed, the cross-sectional area of the dust guide flow path 240 is reduced toward the opening 252 side from the inlet 242 side.

Here, although the cross-sectional area of the dust guide flow path 240 is formed to decrease toward the opening 252 side from the inlet 242 side, since the opening 252 which is the outlet of the dust guide flow path 240 is formed at the lower side, Dust may be smoothly discharged to the opening 252.

On the other hand, the partition plate 250 is rotatable by a hinge on the lower side of the dust separation unit 230. In this case, the hinge 236 is formed below the first guide part 234. In this case, when the dust separation unit 230 is accommodated in the dust collecting body 210, the hinge 236 is accommodated in the second guide portion 215, the hinge 236 and the dust collecting body ( 210) Contact with the inner circumferential surface is prevented.

In addition, a hook 254 is upwardly formed on the partition plate 250 so that the partition plate 250 is coupled to the dust separation unit 230, and the hook 254 is formed on the bottom surface 232. The engaging end 235 is formed.

The dust separation process and the discharge process in the dust separation unit will be described.

The air sucked into the first cyclone unit 231 through the suction unit 233 is rotated along the inner circumferential surface of the first cyclone unit 231 to separate dust. The separated dust is discharged to the dust guide flow path 240 in the tangential direction. In addition, the dust flowing into the dust guide flow path 240 is switched in the flow direction therein, and is dropped downward through the opening 252 is stored in the first dust storage unit 214.

Therefore, as the dust separated from the first cyclone portion 231 is discharged in the tangential direction of the first cyclone portion 231, that is, the dust is discharged in the same direction as the rotation direction, the density is increased. Not only relatively large dust is easily discharged, but also relatively small dust is easily discharged from the first cyclone portion 231.

In addition, as the low-density dust is easily discharged, the low-density dust does not accumulate in the filter member 280, so that smooth flow of air is possible, thereby further improving the dust separation performance. Can be.

In addition, the foreign matter introduced into the dust guide flow path 240 is changed in its flow direction and discharged to the first dust storage unit 214, the dust stored in the first dust storage unit 214 is scattered Is prevented, and backflow to the first cyclone portion 231 is prevented.

That is, since the flow direction of the dust to be flowed back through the dust guide flow path 240 and the flow direction of the dust flowing into the dust guide flow path 240 become the opposite direction, the dust stored in the first dust storage unit 214 Reverse flow is prevented.

FIG. 10 is a cross-sectional view taken along line II ′ of FIG. 3.

Referring to FIG. 10, the dust collecting body 210 has a pair of pressing members 221 and 222 which reduce the volume of dust stored in the first dust storage unit 214 to increase dust collection capacity. ) Is provided.

Here, the pair of pressing members 221 and 222 compress the dust by interaction with each other to reduce the volume of the dust, so that the density of the dust stored in the first dust storage unit 214 is By increasing, the maximum dust collecting capacity of the first dust storage unit 214 is increased.

In detail, the pair of pressing members 221 and 222 may include a first pressing member 221 fixed to a fixed shaft 224 protruded to a bottom surface of the dust collecting body 210, and the fixed shaft 221. The second pressing member 222 is fixed to the rotating shaft 226 is rotatably coupled to the. That is, the first pressing member 221 becomes a fixing member, and the second pressing member 222 becomes a rotating member.

In addition, the driven shaft 226 is coupled to the driven gear 228 rotated by an external drive source.

Here, although not shown, the cleaner body 100 includes a driving gear engaged with the driven gear 228 and a driving motor for driving the driving gear.

Therefore, when the drive motor is driven, the drive gear and the driven gear 228 is rotated, the second pressing member 222 is rotated by the rotation of the driven gear 228.

At this time, the second pressing member 222 is preferably rotated in both directions so that the compression of dust on both sides of the first pressing member 221, the drive motor is a synchronous motor (sychronous motor) ) Can be used.

In the present embodiment, at least one of the pair of pressing members 221 and 222 is provided to be movable inside the dust collecting body 210, but unlike the pair of pressing members 221 and 222. All of them may be provided to be movable inside the dust collecting body 210.

Here, in order to prevent the falling of the dust stored in the first dust storage unit 214 through the opening 252 by the first pressing member 221, the first pressing member 221 is the It is preferably located opposite the opening 252 with respect to the central axis of the dust collecting body (210).

In addition, an upper end of the second pressing member 222 may be formed with a cutout 223 (Chamfer) cut at a predetermined angle. The cutout 223 has a space formed between the opening 252 and the second pressing member 222 when the upper end of the first pressing member 222 is positioned below the opening 252. In this case, dust is easily discharged through the opening 252.

Hereinafter, the operation of the vacuum cleaner according to the present invention will be described.

First, when power is applied to the suction motor of the vacuum cleaner 10, suction force is generated by the suction motor, and air containing dust is sucked into the suction nozzle by this suction force.

In addition, the air sucked through the suction nozzle is introduced into the cleaner body 100 through the main body suction part 110, and the introduced air is introduced into the dust collector 200 through a predetermined flow path.

In detail, the dust-containing air is sucked in the tangential direction of the first cyclone portion 231 through the first air inlet 218 of the dust collecting body 210. In addition, the sucked air falls while turning along the inner circumferential surface of the first cyclone portion 231, and in this process, the air and the dust are separated from each other while receiving different centrifugal forces by the weight difference.

The dust separated air is filtered through the through hole 282 of the filter member 280 and then discharged to the outside of the dust collector 200 through the discharge hole 274 and the first air outlet 271. do.

On the other hand, the separated dust is introduced into the dust guide flow path 240 in the tangential direction in the process of turning along the inner circumferential surface of the first cyclone portion 231.

In addition, the dust flowing into the dust guide flow path 240 is changed in the flow direction in the interior of the dust guide flow path 240, falling down through the opening 252 to the first dust storage unit 214 Are stored in.

Meanwhile, air discharged through the first air outlet 271 is introduced into the cleaner body 100. In addition, the air introduced into the cleaner body 100 is introduced into the second cyclone unit 300 through the connection passage 114.

The air is guided in a tangential direction to the inner wall of the second cyclone portion 300 through a second air inlet (not shown) connected to the end of the connection flow passage 114, and the dust flows again while flowing therein. Are separated.

In addition, the air from which the dust is separated again flows into the cleaner body 100. In addition, the air introduced into the cleaner body 100 is discharged to the outside through the body discharge part of one side of the cleaner body 100 through the suction motor.

On the other hand, the separated dust is introduced into the dust collector 200 through the dust inlet 272, and finally stored in the second dust storage unit 216.

As the dust in the air is separated and dust is stored in the dust storage unit as described above, the pair of pressing members 221 and 222 compress the dust stored in the first dust storage unit 214.

According to the present invention as proposed has the following effects.

First, the dust guide flow path is formed to guide the dust separated from the air in the tangential direction from the first cyclone portion, thereby improving the dust separation performance in the dust separation unit.

That is, the dust separated from the first cyclone portion is discharged in a direction that is compatible with the flow direction of air and dust flowing into the first cyclone portion, so that the dust having a relatively high density as well as the dust having a relatively low density In addition, the first cyclone portion can be easily discharged so that dust does not remain in the first cyclone portion.

Further, as the dust having a small density does not remain in the dust separation unit, the dust having a small density does not remain in the filter member and does not block the airflow, so that the air is smoothly introduced and discharged and the dust separation performance is achieved. This is improved.

Second, the dust guide flow path is provided separately to the outside of the first cyclone portion, and the flow direction of the dust introduced into the dust guide flow path is configured to be switched therein, so that the scattering and backflow of the dust stored in the dust storage unit Has the effect of being prevented.

Third, there is an effect that the user can easily accommodate the dust separation unit in the dust collection body by providing a guide portion for guiding the dust separation unit to the dust collection body. And, as the accommodation of the dust separator is guided, it is possible to further obtain an effect of guiding the coupling of the cover member to which the dust separator is fixed and the dust collecting body.

Fourth, since the dust stored in the dust collector is compressed by a pair of pressing members to minimize the volume thereof, there is an effect of maximizing the dust collection capacity of the dust stored in the dust collector.
