Description

Dust separating apparatus of vacuum cleaner {Dust separating apparatus of vacuunm cleaner}

An embodiment of the present invention relates to a dust separation apparatus of a vacuum cleaner.

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 body, and then filters the dust inside the body.

Such a vacuum cleaner may be distinguished by a canister method in which a nozzle part, which is a large suction port, 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, a conventional vacuum cleaner includes a cleaner body and a dust collecting container mounted on the cleaner body to store dust separated from the air. Such a dust collecting vessel is mainly configured to separate dust by the cyclone principle.

The performance of the vacuum cleaner configured as described above may be substantially determined according to the height of the separation performance of the dust. Therefore, a vacuum cleaner which continuously improves dust separation performance has been proposed.

In addition, the user side should separate the dust collecting container from the cleaner body so that the user can easily discharge dust.

Embodiments of the present invention have been proposed under the background as described above, and an object of the present invention is to propose a dust separation apparatus of a vacuum cleaner, which improves dust separation performance by improving a flow path of a cyclone flow.

In addition, an object of the present invention is to propose a dust separation apparatus of a vacuum cleaner to simplify the structure of the dust collecting container in which dust is stored so that the user can easily discharge the dust.

It is also an object of the present invention to propose a dust separation apparatus of a vacuum cleaner, which enables a user to handle a dust collecting container with little effort.

Dust separation apparatus of a vacuum cleaner according to an embodiment for achieving the object as described above, the dust separation unit to suck the air to separate the dust in the air; And a dust storage unit provided at one side of the dust separation unit and storing dust separated from air, wherein the dust separation unit includes an air intake unit through which air is sucked and separation of air sucked through the air intake unit; And a plurality of air outlets for discharging the air from which the dust is separated, and a dust discharge unit for discharging the dust.

According to another aspect of an apparatus for separating dust from a vacuum cleaner, an air suction unit is formed, and at least a first cyclone flow and a second cyclone flow are generated from the dust separator; And a dust collecting container in which dust separated from the dust separating unit is discharged and stored, wherein the first cyclone flow and the second cyclone flow are moved in a direction away from each other.

According to the embodiment of the above configuration, as the air inlet and the plurality of air outlets are formed in the cyclone, a plurality of cyclone flows are generated inside the cyclone, so that the flow path area of the air is increased. As a result, the flow path loss of the air is reduced to increase the separation performance.

In addition, as the separate cyclone unit is combined with the dust separation, the dust separation performance is improved and the cyclone flow is stabilized as compared with the case of a single cyclone unit.

In addition, since the dust discharge portion is formed in the cyclone portion in a tangential direction, the dust discharge portion can be discharged in the same direction as the dust rotates, so that dust having a relatively high density can be easily discharged, and dust having a relatively low density can also be discharged. There is an effect that can be easily discharged from the clone portion.

In addition, the dust collecting container for storing the dust is provided as a separate item from the dust separation unit, and since the dust collecting cover is provided on one side of the dust collecting container, the user can open the dust collecting cover in the state in which the dust collecting container is removed to empty the dust. In addition, there is an effect of improving the handling of the dust collecting container of the user.

In addition, since the sealing member is provided at the dust inlet of the dust collecting container, the dust inlet is shielded from the outside in a state in which it is coupled with the dust outlet, so that dust does not have to be leaked to the outside in the process of introducing dust.

Hereinafter, with reference to the drawings will be described a specific embodiment of the present invention. However, the spirit of the present invention is not limited to the embodiments presented, and those skilled in the art who understand the spirit of the present invention can easily suggest other embodiments within the scope of the same idea.

1 and 2 are perspective views schematically showing a dust separation apparatus of a vacuum cleaner according to an embodiment of the present invention, Figure 3 is an exploded perspective view of the dust separation apparatus of a vacuum cleaner according to an embodiment of the present invention.

1 to 3, a dust separator 1 of a vacuum cleaner according to an embodiment of the present invention includes a dust separator 10 for separating dust from sucked air, and the dust separator 10. Dust collection container 20 for storing the dust separated from the), and the suction guide tube 40 for guiding the movement of the air containing dust to the dust separation unit 10.

In detail, the suction guide tube 40 is a part for guiding the air sucked from the surface to be cleaned through the suction nozzle (not shown) to move to the dust separation unit 10. In addition, the suction guide tube 40 may be provided inside the cleaner body, and located below the dust collecting container 20.

In addition, the dust separation unit 10 is a portion to separate the dust from the air moved along the suction guide tube (40). In addition, the dust separation unit 10 includes a cylindrical cyclone unit 110 in order to separate the dust in the air by the cyclone principle.

In addition, the cyclone unit 110 is provided with an air suction unit 120 to allow air to be sucked into the dust separation unit 10. Here, the air intake 120 may be formed in the tangential direction of the cyclone portion 110 in order to generate a cyclone flow inside the cyclone portion 110. In addition, the air air suction unit 120 is connected to the suction guide tube 40.

That is, the dust separation apparatus 1 according to the present invention allows the air sucked into the suction guide tube 40 to be sucked into the dust separation unit 10 through the air suction unit 120.

In addition, the air suction unit 120 is formed at the center of the cyclone unit 110, and a branching unit for distributing air to the cyclone unit 110 is not required. Therefore, there is an advantage that the phenomenon that the bulky foreign matter contained in the air is caught in the branch portion can be prevented.

Meanwhile, a dust discharge hole 131 is formed at the central portion of the cyclone part 110 to discharge dust separated from the cyclone part 110. In addition, an outer side of the cyclone unit 110 has a dust discharge unit 130 extending to allow the dust discharged through the dust discharge hole 131 to enter the dust collecting container 20.

Therefore, the dust in the air sucked through the air inlet 120 is separated from the air by the cyclone flow in the cyclone unit 110 and is moved to the center portion of the cyclone unit 110. Then, the moved dust is moved to the dust discharge unit 130 through the dust discharge hole 131 is discharged to the dust collecting container 20 of the lower side.

Here, the dust discharge unit 130 may be formed in the tangential direction of the cyclone unit 110 to facilitate the discharge of dust.

As the dust separated from the cyclone part 110 is discharged in the tangential direction of the cyclone part 110, that is, the dust is discharged in the same direction as the direction in which the dust is rotated, the dust having a relatively high density is easy. In addition to being easily discharged, dust having a relatively low density can also be easily discharged from the cyclone unit 110.

In addition, since the low-density dust is easily discharged, the low-density dust is not accumulated in the filter member to be described later, so that the air can be smoothly flowed, and thus the dust separation performance can be further improved. .

That is, as the air suction unit 120 and the dust discharge unit 130 are formed in the tangential direction of the cyclone unit 110, the dust is sucked into the cyclone unit 110 and the dust discharge unit ( The flow curve up to discharge through 130 may be located on the same plane when projecting from one side of the cyclone part to the other.

In this way, the flow curve of the dust is located on the same plane means that the dust is smoothly separated from the air by the cyclone flow, the separated dust can be smoothly discharged from the cyclone portion (110).

In addition, a pair of air discharge parts 140 are formed on both sides of the cyclone part 110 to discharge air from which dust is separated from the cyclone part 110. In addition, the air discharged through the air discharge unit 140 is introduced into the cleaner body in a state in which the air is discharged from the lamination passage 142.

On the other hand, the dust collecting container 20 is a portion to store the dust separated in the dust separation unit 10. The dust collecting container 20 communicates with the dust separating unit 10 as the dust collecting container 20 is mounted on the cleaner body.

In detail, when the dust collecting container 20 is mounted on the cleaner body, the dust collecting container 20 is located under the dust separating unit 10. Therefore, the dust inlet 210 is formed above the dust collecting container 20. In addition, the dust discharge unit 130 extends downward from the cyclone unit 110.

Therefore, since the dust separated from the cyclone unit 110 moves downward along the dust discharge unit 130, the separated dust can be easily introduced into the dust collecting container 20.

The dust collecting cover 30 is coupled to the lower side of the dust collecting container 20 to discharge dust stored therein. The dust collecting cover 30 may be rotatably coupled to the dust collecting container 20, and may be detachably coupled to the dust collecting container 20.

Therefore, since the user only needs to empty the dust by opening the dust collecting cover 30 in the state in which the dust collecting container 20 is separated, there is an effect of improving the handling of the dust collecting container 20 of the user. Note that the present invention is not limited to the method of coupling the dust cover 30.

As such, the dust collecting container 20 is provided as a separate article from the dust separating unit 10 and configured to selectively communicate with the dust separating unit 10. Therefore, the user may separate only the dust collecting container 20 to discharge dust stored in the dust collecting container 20 to the outside.

In addition, only a space for storing the dust separated by the dust separation unit 10 is formed inside the dust collecting container 20. Therefore, the structure of the dust collecting container 20 is simplified and the weight of the dust collecting container 20 is minimized.

In addition, since the weight of the dust collecting container 20 is minimized, the user can easily lift or handle the dust collecting container 20, and dust is transferred to the outside as the internal structure of the dust collecting container 20 is simple. It can be discharged smoothly, the user can easily clean the interior of the dust collecting container (20).

Hereinafter will be described in more detail according to an embodiment of the internal structure of the dust separation unit 10 according to the present invention.

4 is a cross-sectional view taken along the line II ′ of FIG. 1, and FIG. 5 is a cross-sectional view of the first embodiment taken along line II-II ′ of FIG. 1.

4 and 5, as described above, the air suction unit 120 is formed at the central portion of the cyclone unit 110. The air intake unit 120 may be formed in a tangential direction of the cyclone unit 110.

In addition, both sides of the cyclone unit 110 around the air inlet 120 is formed with an air outlet 140 through which the air from which dust is separated. Therefore, since the air sucked through the air intake unit 120 flows in both directions toward the air discharge unit 140, a pair of cyclone flows corresponding to each other are formed in the cyclone unit 110. Is formed.

That is, the air sucked through the air inlet 120 passes through a cyclone flow, and the dust separated from the air that has undergone the cyclone flow is formed on the opposite side of the air inlet 120. Emitted through. In addition, the air from which the dust is separated may be distributed to both sides in the cyclone unit 110 and discharged through the air discharge unit 140.

As the pair of cyclone flows are generated in a single space as described above, the flow path area of the air is increased, and thus, the loss of the flow path of the air can be reduced and the separation performance can be increased.

As a pair of cyclone flows are generated in a single space, the size of the cyclone portion may be smaller than that of a structure in which one cyclone flow is generated as in the related art.

In addition, as a pair of cyclone flows are generated in a single space, it is possible to obtain the same dust separation performance as a structure in which a conventional air passes through a plurality of dust separation units, and thus, dust from the air discharged from the dust separation unit. No additional dust separator is required to separate the dust again. However, of course, the present invention may further provide an additional dust separator.

In addition, when the diameter of the central portion of the cyclone portion 110 is formed larger than the diameter of both ends, the central portion of the cyclone portion 110 may be configured to be seated on the upper side of the dust collecting container (20). That is, the dust collecting container 20 may be formed with a mounting groove having a shape corresponding to the diameter of the central portion of the cyclone portion (110).

On the other hand, on both sides of the cyclone portion 110, the discharge hole 116 through which the air from which the dust is separated from the cyclone portion 110 is discharged, respectively.

And, each of the discharge hole 116 is coupled to the filter member 150 for filtering the discharged air. In detail, the filter member 150 is formed in a cylindrical shape, a fastening part 152 fastened to the inside of the cyclone part 110, and extended from the fastening part 152 to filter air and have a conical shape. It is composed of a filter unit 154 is formed. In addition, the filter unit 154 has a plurality of through holes 156 through which air flows.

Therefore, the air from which dust is separated from the cyclone unit 110 is discharged from the cyclone unit 110 through the discharge hole 116 via the through hole 156.

As described above, in the present invention, the air is sucked into the cyclone unit 110 through the air inlet unit 120, and the air from which dust is separated from the cyclone unit 110 has a plurality of discharge holes. It is configured to be discharged from the cyclone unit 110 through 116.

Therefore, as the air sucked into the cyclone unit 110 through the air suction unit 120 is discharged through the plurality of discharge holes 116, the air can be smoothly discharged. In addition, the smooth discharge of air from the cyclone unit 110 allows the suction force to be substantially increased, and allows the cyclone flow to be smoothly performed within the cyclone unit 110.

In addition, even when dust is accumulated in one filter member and air does not flow smoothly, the air may be discharged through the other filter member, so that the suction performance of the air may be prevented from dropping rapidly.

On the other hand, the cyclone portion 110 is formed with an opening 112 for replacing the filter member 150. In addition, the opening 112 is selectively shielded by the cover member 160. In addition, a sealing member 114 is provided at a coupling portion of the opening 112 and the cover member 160.

Here, the cover member 160 is preferably formed so that the inner surface has the same curvature as the inner surface of the cyclone portion 110 in a state coupled to the opening 112. That is, the inner peripheral surface of the cover member 160 and the cyclone portion 110 is formed continuously.

Therefore, the cyclone flow inside the cyclone part 110 is prevented from being changed by the cover member 160, and can be kept constant.

As the cover member 160 is detachably coupled to the opening 112, the user may easily replace the filter member 150 by detaching the cover member 160.

Meanwhile, a dust storage unit 201 in which dust is stored is formed in the dust collecting container 20, and a dust inlet 210 in which dust is introduced is formed above the dust collecting container 20. At this time, the dust inlet 210 is in communication with the dust discharge unit 130 as the dust collecting container 20 is mounted on the cleaner body.

Therefore, the dust inlet 210 is provided with a sealing member 220 for sealing the contact portion of the dust inlet 210 and the dust outlet 130. Therefore, since the dust inlet 210 is shielded from the outside in a combined state with the dust discharge unit 130, there is no fear that dust may leak to the outside during the inflow of dust.

In this case, the sealing member 220 may be provided to the dust discharge unit 130.

In addition, the dust collecting container 20 is mounted to the cleaner body in a state inclined at a predetermined angle. In other words, the dust collecting container 20 is detachably coupled to the dust discharge unit 130, and the dust collecting unit 20 on the dust inlet unit 210, that is, the portion coupled to the dust discharge unit 130. One side of the) is characterized in that it is located higher than the other side.

Therefore, since the dust introduced through the dust inlet 210 is sequentially accumulated from the other side of the dust inlet 210, a phenomenon in which dust accumulates only on one side of the dust collecting container 20 can be prevented.

Here, the dust collecting container 20 is provided as a separate article and configured to selectively communicate with the dust separation unit 10, the dust collecting container 20 within the range that can be mounted on the cleaner body The size of the container 20 can be adjusted. In this case, it is possible to obtain an advantage that the amount of dust stored in the dust collecting container 20 can be increased.

Hereinafter will be described the operation of the dust separation apparatus according to an embodiment of the present invention.

6 and 7, when suction force is generated in the cleaner body, air containing dust is moved along the suction guide tube 40, and the cyclone unit 110 is disposed through the air suction unit 120. Is sucked in the tangential direction.

In addition, the sucked air is pivoted along the inner circumferential surface of the cyclone part 110 and moved in both directions from the center of the cyclone part 110. In this process, air and dust are separated from each other under different centrifugal forces due to their weight differences.

In addition, the separated dust is discharged to the outside of the cyclone unit 110 through the dust discharge hole 131. Then, the discharged dust is moved along the dust discharge unit 130 and flows into the dust collecting container 20.

On the other hand, the air is separated dust is moved to both sides, the air is filtered through the through-hole 156 of the filter member 150 and then discharged from the cyclone unit 110 through the discharge hole 116 do. In addition, the discharged air is moved along each of the air discharge parts 140, and is introduced into the cleaner body in a state where the discharged air is combined in the lamination passage 142.

According to the configuration as described above, the area of the flow path of the air in the dust separation apparatus is increased, the dust separation performance is improved, there is an advantage that the air flow flowing into the cleaner smoothly.

In addition, before the air containing the dust is sucked into the dust separation unit, there is no need for a separate branch for branching the air, thereby preventing the phenomenon that the bulky foreign matter is caught in the branch. have.
