Vacuum cleaner {Vacuunm cleaner}

This embodiment relates to a vacuum cleaner.

The present embodiment relates to a vacuum cleaner, and more particularly, to a vacuum cleaner for improving the structure of the vacuum cleaner to improve the suction performance of the 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 should be able to smoothly flow the air sucked from the suction nozzle inside the cleaner body, and the dust may be easily separated from the air including the dust. This is an important criterion for determining the performance of the vacuum cleaner.

On the other hand, the vacuum cleaner is formed with a flow path through which the sucked air is moved. The flow path may be formed in various shapes from an inlet of the cleaner body to an outlet of the suction motor.

The suction and flow performance of the air inside the vacuum cleaner is greatly influenced by whether or not there is a break in the flow path. In detail, the air is preferably flowed in one direction and the flow loss is reduced when the bending is minimized.

However, in the case of the conventional vacuum cleaner, in many cases, a complicated flow path is formed in a limited space of the main body so that the flow direction of air is bent. That is, there has been a problem that the bending of the euro increases.

In this case, there is a problem that the flow loss increases during the movement of the air, the air flow is not smooth.

In addition, there is a problem that the foreign matter is not easily separated from the air because the air flow is not smooth.

An object of the present embodiment is to provide a vacuum cleaner for forming a flow path for allowing the air sucked into the main body to easily flow into the dust separation apparatus.

In addition, an object of the present invention is to provide a vacuum cleaner including a flow path rounded so that the bending of the air flow sucked into the cleaner can be minimized.

The vacuum cleaner according to the present embodiment for solving the above problems, the main body is formed air inlet; An internal flow path formed in the main body and configured to move air introduced from the air inlet; A dust separation chamber for separating dust from the air introduced from the air inlet; A dust collecting unit detachably coupled to the dust separation chamber and storing dust separated from the dust separation chamber; A flow path forming part disposed inside the dust collecting unit and interposed between the inner flow path and the dust separation chamber, wherein the flow path forming part includes a first flow path forming part including an inclined surface extending round from one side of the inner flow path; And a second flow path forming part extending from the first flow path forming part to one side of the dust separation chamber, wherein the flow path forming part includes a lower connection part connected to a bottom part of the dust collecting unit, and the dust separation chamber; It is characterized in that the upper connection portion is formed to be connected.

According to another aspect of the present invention, a vacuum cleaner includes: a main body in which an internal flow path for allowing air to move in one direction is formed; A dust separation chamber in which an air suction unit is formed to suck air passing through the inner flow path in another direction; A dust collecting unit detachably coupled to the dust separation chamber and storing dust separated from the dust separation chamber; And a connection part provided inside the dust collecting unit and connecting the inner flow path and the dust separation chamber, wherein the connection part extends in a direction from the first connection part toward the dust separation chamber, the first connection part forming a curved surface; And a second connection part, wherein the flow path forming part includes a lower connection part connected to the bottom part of the dust collecting unit and an upper connection part connected to the dust separation chamber.

According to the embodiment of the above configuration, there is an advantage that the flow loss can be reduced by forming a flow path that can minimize the bending of the air flow.

In particular, since the flow path extending from the connection pipe provided inside the cleaner to the inside of the dust collecting unit is rounded, there is an advantage that the air flow can be made smoothly.

In addition, friction between the air flow and the flow path forming portion is reduced, there is an advantage that noise due to friction 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.

Meanwhile, the dust collecting unit 110 includes a flow path forming unit 120 that forms a moving flow path of air introduced into the dust collecting unit 110.

Hereinafter, the structure of the said flow path formation part 120 is demonstrated with reference to drawings.

Figure 4 is a perspective view showing the bottom of the dust separation apparatus according to an embodiment of the present invention, Figures 5 and 6 is a perspective view showing the configuration of the flow path forming portion according to an embodiment of the present invention, Figure 7 is the I- of FIG. It is sectional drawing cut along I '.

4 to 7, an inlet hole 114 is formed in the bottom portion 112 of the dust collecting unit 110 according to an embodiment of the present invention to allow air to flow into the dust collecting unit 110. .

In addition, an upper side of the inflow hole 114 is provided with a flow path forming unit 120 that forms a moving flow path of air. That is, the inlet hole 114 forms the lower end of the flow path forming unit 120.

In detail, the flow path forming part 120 includes a first forming part 121 communicating with the inflow hole 114 and a second forming part 122 extending upward from the first forming part 121. Included.

The first forming portion 121 extends round from the bottom portion 112 of the dust collecting unit 110 toward the second forming portion 122. That is, the first forming part 121 includes an inclined surface 121a connecting the inflow hole 114 and the second forming part 122.

The inclined surface 121a may be referred to as a curved surface extending with a predetermined curvature.

The second forming part 122 extends upward from one side of the first forming part 121. In addition, the second forming part 122 may have a pipe shape. In the figure, but having a hollow rectangular parallelepiped, various shapes such as cylinders may be applied.

In addition, the flow path forming part 120 has a lower connection part 123 connected to the bottom part 112 of the dust collecting unit, and an upper connection part 124 connected to the dust separation chamber 150.

Here, the lower connection part 123 may be referred to as an inlet of the flow path forming part 120, and the upper connection part 124 may be referred to as an outlet part of the flow path forming part 120.

The lower connection part 123 includes a lower end of the first forming part 121 and a lower end of the second forming part 122. Here, the lower end of the first forming part 121 forms the inlet hole 114 and the lower end of the second forming part 122 is shielded by the bottom part 112.

In summary, the lower end of the first forming part 121 is opened to allow air to flow therein. On the other hand, since the lower end of the second forming part 122 is shielded by the bottom part 112, the inflow of air is prevented.

Therefore, the air introduced through the inlet hole 114 is moved while forming a predetermined angle with respect to the bottom portion 112 while passing through the first forming portion 121. In addition, the air that has passed through the first forming part 121 may be introduced into the chamber 150 through the second forming part 122.

In addition, the upper connection part 124 is connected to the air intake part 152.

Of course, the upper connection portion 124 is formed by opening the air to pass through. Air passing through the upper connection part 124 is introduced into the dust separation chamber 150 through the air suction part 152.

In the drawing, although the flow path forming part 120 and the air intake part 152 are shown to be separately coupled, the flow path forming part 120 may alternatively be formed integrally with the air intake part 152. .

On the other hand, the flow path forming unit 120 may have a function of connecting the flow path pipe 14 and the air intake unit 152 may be referred to as a "connecting unit". In this case, the first forming part 121 may be referred to as a "first connection part" and the second forming part 122 may be referred to as a "second connection part".

In addition, a lower part of the flow path forming part 120 is provided with a coupling boss 125 that allows the flow path forming part 120 to be coupled to the bottom surface of the dust collecting unit 110.

In addition, the dust collecting unit 110 is provided with a coupling protrusion 113 coupled to the coupling boss 125 at a position corresponding to the coupling boss 125.

8 and 9 are cross-sectional views showing air flow according to an embodiment of the present invention.

8 and 9, a process in which air introduced into the main body 10 is sucked into the dust separation chamber 150 will be described.

Below the dust collecting unit 110, a connection pipe 14 is formed to form a flow path through which air moves from the air inlet 12 of the main body 10 to the dust collecting unit 110.

Since the connection pipe 14 forms an air flow path inside the body 10, the flow path formed by the connection pipe 14 may be referred to as an “inner flow path”.

Air moving along the connection pipe 14 is introduced into the dust collecting unit 110 through the inlet hole 114.

In addition, the first forming part 121 is extended to one side of the connection pipe 14.

Therefore, the air introduced through the inlet hole 114 is moved along the curved surface of the first forming part 121. Thus, the direction of movement of the air changes smoothly while forming a predetermined radius of curvature.

That is, the air may gradually change in direction while passing through the inclined surface 121a.

Therefore, there is an advantage that the flow loss can be minimized because the sudden change of direction, that is, the bending of the flow path is not large during the process of moving the air.

In addition, the air passing through the first forming part 121 may be guided by the second forming part 122 and moved to the air suction part 152.

A flow direction that is moved along the connecting pipe 14 is referred to as "a (first direction)", and a flow direction that is moved along the outlet of the flow path forming part 120, that is, along the air intake part 152. Assume "b (second direction)".

Here, the "a" and "b" may be formed in a direction orthogonal to each other.

Here, the direction of the flow formed in the flow path forming unit 120 forms a "c (third direction)" different from the "a" and "b".

That is, by the flow path forming part 120, the air can be prevented from rapidly changing from the direction "a" to the direction "b" during movement. In this case, there is an advantage that the flow loss of air is reduced.

In addition, while the bending of the flow path is minimized, the friction generated between the portion forming the flow path and the flow is reduced, there is an advantage that the noise is reduced.

In addition, the air introduced into the dust separation chamber 150 is separated by dust while performing cyclone flow. The separated dust is discharged through the dust discharge unit 154, and the air from which the dust is separated is discharged through the air discharge unit 153.
