The present invention relates to an improvement in a branch where 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 has a narrow width, which is difficult for the user to clean.

The present invention has been proposed under the background as described above, and proposes a vacuum cleaner to improve the flow path through which the air containing dust is moved so that the air can be smoothly flowed to the dust collector without the foreign matter caught in the branch. The purpose.

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 branch portion having one side connected to each of the air intake portions, and a branch portion having an air inlet portion through which air is introduced, and the branch portion having a plurality of branch passages through which air introduced from the air inlet portion is distributed. An intermediate passage in which at least a portion of the air introduced from the air inlet is moved in communication with the branch passage is included, and the branch passage has a larger cross-sectional area than the intermediate passage.

Dust separation apparatus of the vacuum cleaner of the present invention according to another aspect, the dust separation unit is formed a plurality of air intake; One side is connected to the dust separation unit, the other side is a branch in which the air inlet is formed air is introduced; And a plurality of branch flow paths formed in the branch portion, the plurality of branch flow paths through which air is distributed to each of the air intake parts, and an intermediate flow path formed between the branch flow paths, and the thickness of the branch portion on the branch flow path side being the middle. It is characterized in that it is formed larger than the thickness of the branch part of the flow path side.

According to the present invention according to the above configuration, since the width of the branch portion to which the air flow is distributed varies depending on the location there is an advantage that the phenomenon that the foreign matter caught in the branch can be minimized.

In addition, since the branch has a long vertical pipe shape, there is an effect that the flow is smooth, including a large volume of foreign matter in the moving air.

In addition, since air is equally distributed before being sucked into the plurality of air intakes, there is an effect that the phenomenon that bulky foreign matters are caught in the air intakes can be reduced.

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.

In addition, the dust separation unit 20 is provided with a first air suction unit 211 and a second air suction unit (to be described later) on which both air is sucked, and air is sucked through each air suction unit.

In addition, the branch portion 10 is connected between the suction guide tube 30 and the dust separation unit 20, the air flow moved along the suction guide tube 30 is the dust separation unit 20 Distribute evenly and inhale.

In addition, the branch portion 10 has air distributed between the first and second distribution pipes 111 and 112 to allow air to be distributed to both sides, and the distribution pipes 111 and 112 to the distribution pipes 111 and 112. Dispensing guide 130 is included to guide the movement.

3 is a perspective view showing a branch according to the present invention, FIG. 4 is a cross-sectional view taken along the line II-II 'of FIG. 3, and FIG. 5 is a cross-sectional view taken along the line II ′ of FIG. 1.

3 to 5, the branch part 10 includes a first branch flow path 121, a second branch flow path 122, and an intermediate flow path 123 through which the introduced air is distributed and moved, and the branch flow path. Between the first and second distribution pipes 111 and 112 and the distribution pipes 111 and 112 for guiding the air passing through the 121 and 122 and the intermediate flow path 123 to be sucked into the air suction units 211 and 212. The distribution guide 130 is provided to guide the air passing through the intermediate flow path 123 to each of the distribution pipes (111, 112).

And, the lower end of the branch portion 10 is connected to the suction guide tube 30, the air inlet 124 is formed through which the air passing through the suction guide tube 30 is formed.

In detail, the branch portion 10 is a pipe type having a predetermined thickness as an overall symmetrical shape. The first branch flow passage 121 and the second branch flow passage 122 are formed at both sides of the branch portion 10, and the intermediate flow passage 123 is the first branch flow passage 121 and the second branch flow passage. It is formed between 123.

Here, the first branch passage 121 and the second branch passage 122 are formed to have a large thickness such that a large volume of foreign matter in the air can sufficiently move, whereas the intermediate passage 123 is the first branch passage 121. It is relatively smaller than the branch flow passage 121 and the second branch flow passage 122, and is formed to a thickness such that a large amount of foreign matter does not flow therein.

That is, the branch portion 10 is formed to be recessed from the branch flow path (121, 122) side to the intermediate flow path (123) side.

4 shows the inside of the branch portion 10 with the distribution guide 130 removed.

Referring to FIG. 4, the branch flow passage 121. 122 and the intermediate flow passage 123 communicate with each other, and the air introduced through the suction guide pipe 30 may be any of the branch flow passages 121 and 122 and the intermediate flow passage 123. It is divided into one intermediate flow path.

In detail, a flow for distributing bulky foreign matter in the air introduced into the air inlet 124 to the first branch passage 121 and the second branch passage 122 above the air inlet 124. The distribution unit 125 is formed.

Here, the flow distribution section 125 is in the shape of a recessed branch portion corresponding to the beginning of the intermediate passage 123.

That is, since the cross-sectional area of the intermediate passage 123 through which air passes is formed smaller than the cross-sectional areas of the first branch passage 121 and the second branch passage 122, the volume of the air passing through the air inlet 124 is increased. The large foreign matter does not move to the intermediate flow path 123 and is naturally distributed to the first branch flow path 121 and the second branch flow path 122.

In other words, the flow distribution unit 125 means an opening surface through which air can be introduced, but it is meaningful that bulky foreign substances such as vinyl, tissue, etc. can be filtered out.

On the other hand, in the drawing is divided into two branch passages (121, 122) through which large foreign matter passes through both sides of the branch portion 10, and one intermediate passage (123) through which fine dust can pass, the branch portion ( If the branch flow path and the intermediate flow path can be distinguished by the shape of 10), another embodiment may be proposed with respect to the number of branch flow paths.

In addition, the branch flow paths 121 and 122 and the intermediate flow path 123 serve as intermediate flow paths so that the air moved from the suction guide pipe 30 is evenly distributed to the distribution pipes 111 and 112. In addition, the intermediate flow path 123 is provided in a shape of widening from the lower end connected to the suction guide tube 30 to the upper end leading to the distribution pipes 111 and 112. That is, the intermediate passage 123 is characterized in that the passage cross-sectional area of the distribution pipe (111, 112) is larger than the air inlet 124 side.

In addition, the branch flow paths 121 and 122 and the intermediate flow path 123 have a long vertical length, which means that the air flow from the suction guide pipe 30 can be evenly distributed to the distribution pipes 111 and 112. This is to secure a distance for the purpose. Here, the lengths of the branch passages 121 and 122 and the intermediate passage 123 may be twice the diameters of the distribution pipes 111 and 112.

In addition, each of the distribution pipes (111, 112) is provided on both sides of the branch portion (10). The first distribution pipe 111 is connected to the first air suction part 211, and the second distribution pipe 112 is connected to the second air suction part 212.

The distribution guide 130 extends from the distribution pipes 111 and 112 toward the center of the branch portion 10 and is formed above the intermediate flow path 123. In addition, the distribution guide 130 may be installed between the distribution pipes 111 and 112 so that the first branch flow passage 121 and the second branch flow passage 122 are spaced apart from each other.

In this case, the air passing through the intermediate flow path 123 is guided to be moved to the distribution pipe 110 by the distribution guide 130.

In addition, the distribution guide 130 is the distribution pipe (111, 112), that is, the air intake (211,212) in order for the air to be easily distributed to each of the distribution pipe (111, 112) to move to the air intake (211,212) It is preferable to be formed at an adjacent position of.

On the other hand, the distribution guide 130 may be directly connected to each of the air intakes (211, 212) without being connected to each of the distribution pipes (111, 112).

The distribution pipes 111 and 112 may be inserted into the outside of the air suction parts 211 and 212, and the air suction parts 211 and 212 and the distribution pipes 111 and 112 may be selectively coupled to each other. In addition, a sealing member 113 may be provided between the air intakes 211 and 212 and the distribution pipes 111 and 112.

Meanwhile, the air sucked into the dust separator 20 through the air suction units 211 and 212 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 the air discharge unit provided on both sides of the dust separation unit ( 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.

6 is a cross-sectional view showing the flow of air flow in the branch according to the present invention.

Referring to FIG. 6, the air flowing through the air inlet 124 is distributed to the branch passages 121 and 122 and the intermediate passage 123 and moved upward.

In detail, the bulky foreign matter in the air is distributed to both sides of the flow distribution unit 125, and the distributed air is distributed along the first branch passage 121 and the second branch passage 122, respectively. It is moved to (111, 112).

In addition, small foreign matters such as fine dust may be moved upward through one of the branch passages 121 and 122 and the intermediate passage 123.

Meanwhile, when the air moving upward along the intermediate flow path 123 reaches the distribution guide 130, the air is guided to both sides and moved to each of the distribution pipes 111 and 112.

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 (111, 112) on both sides, the dust contained in the air is the distribution pipe (111,112) ) Has the advantage of minimizing the phenomenon. In addition, there is an effect that the air flow to the dust separation unit 20 is smooth.

On the other hand, since the branch portion 10 has a symmetrical shape, the air flow may be evenly distributed to the distribution pipes 111 and 112 on both sides.

7 is a cross-sectional view showing another embodiment of a branch of the vacuum cleaner according to the present invention.

This embodiment is the same as the embodiment shown in FIG. 5 in other parts, but is characterized in that there is a difference in the structure of the branch portion. Therefore, hereinafter, only the characteristic parts of the present embodiment will be described, and the same reference numerals and descriptions will be used for the same parts as the embodiment shown in FIG.

Referring to FIG. 7, the branching part 10 according to the present exemplary embodiment is provided with a distribution rib 126 that guides the bulky foreign matter in the air to both sides above the air inlet 124.

In detail, the dispensing rib 126 is formed in the flow distribution section 125 and is provided at a position such that the open face of the flow distribution section 125 is shielded. That is, unlike the previous embodiment shown in FIG. 5, since the flow distribution part 125 is closed up and down by the distribution ribs 126, air introduced into the branch part 10 is forced to both sides. It is distributed to branch flow paths 121 and 122.

However, the distribution rib 126 is formed only in the flow distribution part 125, and since the left and right sides of the intermediate flow path 123 are opened, the first branch flow path 121 and the second branch flow path 122. And the intermediate passage 123 communicates with each other.

Therefore, even if the air introduced through the air inlet 124 is distributed to the first branch passage 121 and the second branch passage 122 by the distribution rib 126, the intermediate passage 123 during the movement. ) May be moved to the side.

However, considering that a large volume of foreign matter in the air has a small width or thickness of the intermediate flow path 123, it is limited to move to the intermediate flow path 123. It may be moved to the intermediate flow path 123 side.

By the above configuration, the bulky foreign matter in the air sucked from the surface to be cleaned can be distributed to the left and right flow passages in the branch portion 10 before being sucked into the dust separation unit 20, thereby increasing the volume. Even if a large amount of large foreign substances are introduced into the cleaner at once, the phenomenon that the foreign substances are caught in the intermediate passage 123 or the distribution pipes 111 and 112 may be minimized.
