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

The present invention relates to an improvement of a dust branch in which air is branched in a dust separation apparatus of a vacuum cleaner. In detail, the present invention relates to a dust separation apparatus of a vacuum cleaner for improving a flow path through which dust is moved, so that dust flow is smooth, and dust is easily sucked into the dust container.

The present invention relates to a dust separation apparatus of a vacuum cleaner, and more particularly, to a dust separation apparatus of a vacuum cleaner for improving a flow path through which dust moves, so that dust flow is smooth, and dust is easily sucked into the dust container. It is about.

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 should flow smoothly until the air sucked from the suction nozzle is sucked into the cleaner body, and it is necessary to minimize the phenomenon that foreign substances contained in the air are caught in the flow path during movement. This is an important criterion for determining the performance of the vacuum cleaner.

Meanwhile, in the case of a vacuum cleaner having two or more dust bins or two or more air suction units through which air is sucked into the dust bins, a distribution pipe or branch pipe through which air is distributed from one flow path so that air can be divided and moved to the air suction unit. This is necessary.

In this case, a problem arises in that a bulky foreign matter or the like is not distributed to the distribution pipe and caught in a branching part.

In this case, the performance of the cleaner is deteriorated, and the user needs to open and clean the inside of the cleaner in order to remove foreign substances. In addition, in general, the flow path inside the cleaner is narrow and the user has a lot of difficulties in cleaning.

The present invention has been proposed under the background as described above, and an object of the present invention is to propose a vacuum cleaner which allows air to be smoothly flowed to a dust collector without trapping foreign matters by improving a flow path through which air containing dust is moved. .

It is also an object of the present invention to propose a vacuum cleaner which allows the inhaled air flow to be evenly distributed through the distribution pipe.

Dust separation apparatus of a vacuum cleaner according to the present invention for achieving the object as described above, the dust separation unit is formed with a plurality of air intake; And a dust branch part having one side connected to each of the air intake parts, and an air inlet part being formed at the other side, and the dust separating part being separated from the main flow path through which the air introduced into the inlet part moves, and the main flow path. The distribution flow path is formed, and the main flow passage is characterized in that the flow passage cross-sectional area is larger than the inflow portion side.

According to another aspect, an apparatus for separating dust of a vacuum cleaner according to another aspect of the present invention includes: a main flow path through which air sucked from a surface to be cleaned is moved, and an inlet is formed; A plurality of distribution passages through which air moved along the main passage is distributed in at least two directions; A dust separator is connected to each of the distribution passages and provided with an air suction unit for allowing air to be sucked. The inlet portion is formed to be biased toward one of the distribution passages.

Dust separation apparatus of the vacuum cleaner according to another aspect of the present invention, the dust separation unit is formed with a plurality of air suction portion; One side is connected to the dust separation unit, the other side is a dust branch formed in the air inlet air is introduced; A plurality of distribution passages provided in the dust branch and configured to distribute air to each of the air intake portions; A dispensing guide is provided between the dispensing passages and guides the air to be moved to the dispensing passage. The dispensing guide is inclined to move the air to at least one dispensing passage.

According to the present invention according to the above configuration, since the length and width of the dust branch to which air is distributed are sufficiently secured, the flow is evenly distributed, and the width between the distribution pipes on both sides is secured, so that dust is caught on the distribution pipe. There is an advantage that can be minimized.

In addition, since the shape of the dust branch is eccentric to one side, the bulky dust and fine dust is separated and distributed to each distribution pipe, thereby reducing the phenomenon that the dust is caught in the central portion of the dust branch.

Similarly, since the distribution guide for distributing dust is inclined, bulky dust flows into only one side of the distribution pipes on both sides, and the dust may be caught in the distribution pipe or the distribution guide.

In detail, the dust branch 10 includes a plurality of distribution pipes 110 through which air is distributed to the dust separation unit 20 and sucked, and a main flow path through which air sucked from the suction guide pipe 30 is moved. The distribution guide 130 is formed between the 120 and the distribution pipe 110 to guide the air to be distributed.

Here, the distribution pipe 110 is connected to the air intake 210, is provided on both sides of the dust branch (10). In addition, a distribution flow path 140 through which air is distributed by the distribution pipe 110 is formed, and the distribution flow path 140 is connected to the main flow path 120.

It is provided in a shape that widens from the top to the upper end leading to the distribution pipe (110). That is, the main flow path 120 is characterized in that the flow path cross-sectional area larger than the air inlet 123 side.

In addition, the main flow path 120 has a long vertical length, which ensures a distance for allowing the air flow moved from the suction guide pipe 30 to be evenly distributed to the distribution pipe 110. To do this. Here, the length of the main flow path 120 is preferably twice the diameter of the distribution pipe (110).

In addition, the distribution pipe 110 may be inserted into the outside of the air intake 210, and the air intake 210 and the distribution pipe 110 may be selectively coupled. In addition, a sealing member 112 may be provided between the air intake unit 210 and the distribution pipe 110.

Meanwhile, the air sucked into the dust separator 20 through the air suction unit 210 is moved to the center of the dust separator 20 through a cyclone flow. In addition, the dust in the air is separated and discharged through the dust discharge unit 230 is introduced into the dust collector (not shown), the dust is separated air is an air discharge unit provided on both sides of the dust separation unit 20 Discharged through 220.

In addition, a filter unit 240 is provided inside the dust separation unit 20, and the filter unit 240 is connected to the air discharge unit 220. Therefore, dust is filtered by the filter unit 240 and is not discharged to the air outlet 220.

Hereinafter, the air flow of the present embodiment will be described.

As shown in FIG. 4, a part of the air sucked through the air inlet 123 is moved to the distribution pipe 110 along the inside of the dust branch 10. Then, the remaining air is moved upward through the main flow path 120, and when the air reaches the distribution guide 130, it is guided to both sides and moved to the distribution flow path 140.

Here, the distribution guide 130 is provided in the horizontal direction, the length of the distribution guide 130 is formed long enough as the interval between the distribution pipes 110 on both sides, the dust contained in the air is the distribution pipe 110 ) Has the advantage of minimizing the phenomenon. In addition, there is an effect that the air flow is smooth.

On the other hand, since the dust branch 10 has a symmetrical shape, the air flow is evenly distributed to the distribution pipe 110 on both sides.

5 is a cross-sectional view showing a second embodiment of the dust branch of the vacuum cleaner according to the present invention, Figure 6 is a cross-sectional view showing the flow of air flow in the dust branch according to the second embodiment.

This embodiment is the same as the first embodiment in other parts, but is characterized in that there is a difference in the shape of the dust branch portion. Therefore, hereinafter, only characteristic parts of the present embodiment will be described, and the same reference numerals and descriptions as those of the first embodiment are used.

5 and 6, the dust branch 40 according to the second embodiment of the present invention is asymmetrically from the air inlet 423 to the first distribution pipe 410 or the second distribution pipe 412. It has a shape.

In detail, the distance L1 from the inlet 423 to the first distribution pipe 410, that is, the first distribution channel 440, is defined as the second distribution pipe 412, that is, the first distribution pipe 410. It is formed shorter than the distance L2 to the two distribution flow paths 442. That is, the dust branch 40 has a shape eccentric to the first distribution pipe 410 side.

In more detail, one side of the dust branch 40 extends directly downward from the first distribution pipe 410, and the other side of the dust branch 40 has the air inflow from the second distribution pipe 412. It is formed to be inclined inward to the portion 423. That is, the main flow path 420 through which air is moved has a shape that is wider in the direction of the second distribution pipe 412.

In addition, the first distribution pipe 410 is connected to the first suction unit 510 of the dust separation unit 50, the second distribution pipe 412 is connected to the second suction unit 512, Air distributed to the first and second distribution pipes 410 and 412 is sucked into the first and second suction parts 510 and 512, respectively.

Hereinafter, the air flow of the second embodiment will be described.

Air moving along the suction guide tube 30 is sucked into the dust branch 40 through the air inlet 423. Meanwhile, the sucked air is not evenly distributed to the distribution pipes 410 and 412, and more air flow is distributed to the first distribution pipe 410. And, relatively little air flow is moved to the second distribution pipe 412.

As described above, the distance L1 from the first distribution pipe 410 to the air inlet 423 is the distance L2 from the second distribution pipe 412 to the inlet 423. This is because the shorter than the suction force generated in the air suction unit (510 512) on both sides, the suction force generated in the first suction unit 510 acts more on the moving air.

Therefore, the bulky dust such as a tissue in the moving air preferentially moves to the first distribution pipe 410 side, and the small dust or fine dust moves to the second distribution pipe 412 side.

In addition, the air moved along the main flow path 420 and reaches the distribution guide 430 is also more distributed to the first distribution pipe 410. Because the main flow path 420 is eccentric toward the first distribution pipe 410 side, the distance L3 from the point where air is distributed by the distribution guide 430 to the first distribution pipe 410 is increased. This is because it is shorter than the distance L4 to the second distribution pipe 412.

In summary, since the shape of the dust branch 40 is eccentric to the first distribution pipe 411, bulky dust is distributed to the first distribution pipe 410 and fine dust is discharged to the second distribution pipe ( 412). Therefore, before the air enters the dust separation unit 50, there is an effect that the dust is separated first.

In addition, since the suction force on the side of the first suction part 510 is greater, dust is less likely to be caught on the distribution pipes 410 and 412 or the distribution guide 430, and the air flow to the dust separation part 50 is reduced. It has the advantage of being smooth.

7 is a cross-sectional view showing a third embodiment of the dust branch of the vacuum cleaner according to the present invention, Figure 8 is a cross-sectional view showing the flow of air flow in the dust branch according to the third embodiment.

This embodiment is also the same as in the first embodiment in other parts, except that there is a difference in the shape of the dust branch. Therefore, below, the characteristic part of this embodiment is demonstrated mainly.

7 and 8, the dust branch unit 60 according to the third embodiment of the present invention includes a distribution guide 630 formed to be inclined to one side.

In detail, the dust branch 60 has a symmetrical shape from the air inlet 623 to the distribution pipes 610 and 612. However, unlike the first embodiment described above, the distribution guide 630 is the first distribution pipe 610, that is, the first distribution flow path from the second distribution pipe 612, that is, the second distribution flow path 642. Up to 640 is provided inclined upward.

In more detail, the distribution guide 630 is formed to be inclined by a predetermined angle α about the horizontal axis. That is, the distribution guide 630 is formed to be inclined so that air moves to at least one of the distribution flow paths.

Accordingly, when the flow and dust moving along the main flow path 620 meet the distribution guide 630, the flow and dust are guided along the distribution guide 630 and are first distributed to the first distribution pipe 610.

Here, the angle α is preferably formed at 10 degrees or more in order to achieve an eccentric flow distribution function.

Hereinafter, an air flow according to the present embodiment will be described.

Some of the air sucked through the inlet 623 moves to both sides along the inside of the dust branch 60, and is distributed to the first distribution pipe 611 and the second distribution pipe 612, respectively. Then, the remaining air will be moved upward along the main flow path 620.

On the other hand, since the suction force in the air suction unit (710, 712) is the same, bulky dust such as toilet paper does not bias to one side of the dust branch portion 60, the dust branch portion along the main flow path 620 It will be moved upward through the center of 60.

When the air moving along the main flow path 620 meets the distribution guide 630, the air may be guided by the distribution guide 630 and distributed to the first distribution pipe 610. Therefore, the bulky dust is moved to the first distribution pipe 610 side and is sucked into the dust separation unit 70 through the first suction unit 710.

In summary, air and fine dust are distributed to the second distribution pipe 612, and bulky dust will be distributed to the first distribution pipe 610. Therefore, as in the case of the second embodiment described above, there is an effect that the dust is first separated before air enters the dust separator 70.

In addition, since most of the dust is distributed to the first distribution pipe 610 by the distribution guide 630 inclined upward toward the first distribution pipe 610, the dust is distributed in the distribution pipes 410 and 412 or the distribution guide 430. ) Is not easily caught, there is an advantage that the air flow to the dust separation unit 70 is smooth.

Another embodiment may be proposed within the scope of the spirit of the present invention.

The idea of the invention according to the second embodiment and the idea of the invention according to the third embodiment may be combined.

That is, by varying the shape of the flow path guides provided on both sides of the dust branch portion, the dust branch portion is eccentric, and the distribution guide for guiding air is provided to be inclined upward in the eccentric direction so that the bulky dust is eccentric. It can be made to be distributed to the distribution pipe of the side first.

In this case, the bulky dust may be sucked into the dust separator without being caught in the dust branch, and the air flow in the cleaner may be smoothed.
