The present invention relates to a duct assembly, and more particularly, to a duct assembly for effectively discharging a contaminated fluid by increasing an inflow rate of a wake.

In general, a ventilator is made to keep the indoor air clean by forcibly discharging contaminated indoor air to the outside. Such a ventilator may be provided in various places, such as restaurants, offices, and houses, for example.

Such a ventilator is coupled to a duct, and contaminated air sucked from the room may be discharged to the outside through the duct.

Here, the duct is configured to discharge contaminated air sucked from the ventilator to the outside, and forms a hollow hollow long passage so that a fluid such as air can be discharged to the outside.

1 is a schematic exemplary view showing a state in which a conventional ventilation fan is coupled to a main duct.

As shown in FIG. 1, when a plurality of ventilating fans 20 are coupled to the main duct 10, the air discharged from the ventilating fan 20 is affected by the moving flow of air moving in the discharge direction along the main duct 10. There is a disturbing problem.

In other words, since the exhaust air discharged from the fan 20 is discharged in a direction different from the flow direction of the air moving along the main duct 10 (for example, in a direction perpendicular to), the fan 20 The exhaust air discharged from the main duct 10 interferes with the flow of air moving along the main duct 10.

Therefore, there is a problem in that contaminated air is not smoothly discharged to the outside.

Accordingly, there is a need for various studies on a duct assembly capable of smoothly discharging contaminated air to the outside even if a plurality of ventilating fans are coupled to the main duct.

An object of the present invention for solving the above-described problems is to provide a duct assembly capable of effectively discharging a contaminated fluid to the outside by increasing an inflow rate of a wake.

In order to achieve the above technical problem, one embodiment of the present invention is an external pipe having a first pipe coupled to the power generating unit, a second pipe coupled to the other end of the first pipe and forming a T-shape; An inner pipe provided inside the second pipe, which is spaced apart from the second pipe at predetermined intervals to form a fluid pressurization space, and a communication hole formed at a predetermined interval along the circumference thereof, and an inner pipe having a discharge passage therein ; And a guide part coupled to the inner surface of the inner pipe and guiding the discharge direction of the fluid discharged from the fluid pressurization space part to the discharge passage through the communication hole.

In one embodiment of the present invention, the guide portion, one end is coupled along the inner circumference of the inner pipe, the other end is a first guide protruding obliquely in the direction of the virtual central axis of the inner pipe; And a second guide at one end connected to the first guide, and a second guide protruding obliquely toward an inner surface of the inner pipe, and the other end of the second guide has a predetermined distance from the inner surface of the inner pipe. And can form a fluid discharge hole.

In one embodiment of the present invention, the first guide and the second guide are obliquely protruded in an external discharge direction in which fluid is discharged to the outside, and the guide part allows the fluid discharged from the fluid discharge hole to pass through It can be made to be discharged along.

In one embodiment of the present invention, a separation distance between the other end of the second guide forming the fluid discharge hole and the inner surface of the inner pipe is an inner surface of the second pipe forming the fluid pressurization space It may be formed to be shorter than the separation distance between the inner pipes.

In one embodiment of the present invention, a separation distance between the second pipe and the inner pipe forming the fluid pressurization space may be 1/10 or less than the inner diameter of the first pipe.

In one embodiment of the present invention, a plurality of communication holes formed in the inner pipe are provided at predetermined intervals along the length direction of the inner pipe, and the guide portion is formed in plurality along the length direction of the inner pipe. It may be provided to correspond to the number of communication holes.

In one embodiment of the present invention, a first connection portion provided on the upper end of the inner pipe; And a second connection part provided at a lower end of the inner pipe.

The effects of the duct assembly according to the present invention described above will be described as follows.

According to the present invention, the duct assembly is provided with a guide portion.

This guide portion is configured to guide the movement direction of the fluid discharged from the fluid pressurization space portion to the inner pipe to the inner surface of the inner pipe. At this time, since the fluid pressurized in the fluid pressurization space is discharged through the fluid discharge hole formed between the guide part and the inner pipe, the fluid discharged to the inner surface of the inner pipe can be discharged at a high speed.

In this way, the pressure inside the duct assembly is lowered by the fluid discharged at a high speed through the fluid discharge hole, so that the inflow of the wake can be accelerated. Accordingly, the contaminated fluid can be effectively discharged to the outside.

The effects of the present invention are not limited to the above effects, and should be understood to include all effects that can be inferred from the configuration of the invention described in the detailed description or claims of the present invention.

Hereinafter, the present invention will be described with reference to the accompanying drawings. However, the present invention may be implemented in various different forms, and therefore is not limited to the embodiments described herein. In the drawings, parts irrelevant to the description are omitted in order to clearly describe the present invention, and similar reference numerals are attached to similar parts throughout the specification.

Throughout the specification, when a part is said to be "connected" with another part, this includes not only "directly connected" but also "indirectly connected" with another member interposed therebetween. . In addition, when a part "includes" a certain component, this means that other components may be further provided, not excluding other components, unless specifically stated to the contrary.

In the present invention, the upper and lower portions mean that they are positioned above or below the target member, and do not necessarily mean that they are positioned above or below the gravitational direction.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

As shown in FIG. 2, for example, a main duct 10 is provided on an apartment, multi-family, or other building for exhausting odors and polluted air generated indoors, such as a kitchen or bathroom, to the outside.

A plurality of duct assemblies 1000 may be coupled to the main duct 10, and the contaminated fluid flowing from the plurality of duct assemblies 1000 to the main duct 10 is moved along the main duct 10 and eventually Can be discharged to the outside. This main duct 10 becomes a moving path for discharging the contaminated fluid to the outside.

Here, since the duct assembly 1000 according to the present invention is combined with the main duct 10, it is made so as not to interfere with the flow of the fluid moving along the main duct 10, and the fluid moving along the main duct 10 It is structured to make the flow of flow more effective. At this time, the fluid moving along the main duct 10 is described as an example of air, but it goes without saying that a liquid fluid such as water may move to the duct assembly 1000 and the main duct 10.

3 is a perspective view of a duct assembly according to an embodiment of the present invention, FIG. 4 is a perspective cross-sectional view taken along line II of FIG. 3, and FIG. 5 is a cross-sectional view taken along line II of FIG. 3.

As shown in FIGS. 3 to 5, the duct assembly 1000 may include an outer pipe 100, an inner pipe 200, and a guide part 300.

A power generating unit (not shown) may be coupled to the outer pipe 100 of the duct assembly 1000. Here, the power generating unit is configured to provide power for moving the fluid. This power generating unit is configured to provide power for discharging the inhaled contaminated air to the main duct 10 after sucking contaminated air in the room, for example.

Such a power generating unit may be, for example, a fan or a pump. Here, the power generating unit is not necessarily limited to a fan or a pump, and any one may be used as long as the fluid is discharged to the main duct 10 through the duct assembly 1000.

Meanwhile, the external pipe 100 may include a first pipe 110 and a second pipe 120.

Here, one end of the first pipe 110 is coupled to the power generating unit, and the other end of the first pipe 110 is coupled to the second pipe 120. At this time, the first pipe 110 and the second pipe 120 are combined to form a T-shape.

Accordingly, external fluid may be moved to the second pipe 120 after passing through the first pipe 110 by the operation of the power generating unit.

In addition, the inner pipe 200 is provided inside the second pipe 120.

In the inner pipe 200, communication holes 201 are formed at predetermined intervals along the periphery. A plurality of communication holes 201 formed along the circumference of the inner pipe 200 may be formed along the length direction of the inner pipe 200.

In the present invention, a form in which three communication holes 201 are formed at predetermined intervals along the length direction of the inner pipe 200 will be described as an example. That is, it will be described as an example that three communication holes 201 are formed at predetermined intervals from the first connection part 410 to the second connection part 420 direction. It goes without saying that the number of communication holes formed at predetermined intervals along the length direction of the inner pipe 200 is not limited to three, and may be formed in various numbers.

The inner pipe 200 is spaced apart from the second pipe 120 at a predetermined interval, and a fluid pressurization space portion 202 is formed between the inner surface of the second pipe 120 and the outer surface of the inner pipe 200. To form. That is, the second pipe 120 and the inner pipe 200 are concentric, but the radius of the second pipe 120 is larger than the radius of the inner pipe 200, A fluid pressurization space part 202 may be formed between the side surface and the outer surface of the inner pipe 200.

Here, the separation distance L1 between the second pipe 120 and the inner pipe 200 forming the fluid pressurized space 202 is 1/10 or less than the inner diameter D of the first pipe 110 desirable. Because, as the separation distance L1 between the second pipe 120 and the inner pipe 200 forming the fluid pressurization space 202 is formed smaller than the inner diameter D of the first pipe 110, the first This is because the fluid flowing from the pipe 110 to the fluid pressurization space 202 can be discharged at a high speed through the discharge passage 203 of the inner pipe 200 in a state of being pressurized.

In other words, the fluid pressurization space 202 is a space for maintaining a state of the fluid flowing into the first pipe 110 above a predetermined pressure, and is pressurized by the fluid pressurization space 202 to a predetermined pressure or more. The fluid may be discharged to the discharge passage 203 of the inner pipe 200 at a high speed through the communication hole 201.

Here, when the separation distance L1 between the second pipe 120 forming the fluid pressurized space 202 and the inner pipe 200 exceeds 1/10 of the inner diameter D of the first pipe 110 , Since the fluid pressurization state in the fluid pressurization space 202 is lowered, there is a problem that the discharge speed of the fluid discharged to the inner pipe 200 does not meet the required speed. Accordingly, the separation distance L1 between the second pipe 120 and the inner pipe 200 forming the fluid pressurization space 202 is 1/10 or less than the inner diameter D of the first pipe 110 This is desirable.

Meanwhile, the guide part 300 is coupled to the inner surface of the inner pipe 200.

The guide part 300 is configured to guide the discharge direction of the fluid discharged from the fluid pressurized space part 202 to the discharge passage 203 of the inner pipe 200 through the communication hole 201.

Such a guide part 300 may include a first guide 310 and a second guide 320.

One end of the first guide 310 is coupled along the inner circumference of the inner pipe 200. In addition, the other end of the first guide 310 protrudes obliquely in the direction of the virtual central axis of the inner pipe 200. Here, since it protrudes obliquely from one end of the first guide 310 to the other end, it protrudes obliquely in the direction of discharging the external fluid through which the fluid is discharged to the outside.

The second guide 320 is connected to the first guide 310.

One end of the second guide 320 is connected to the other end of the first guide 310, and the other end of the second guide 320 protrudes obliquely toward the inner surface of the inner pipe 200. Accordingly, the guide part 300 guides the movement of the fluid so that the fluid discharged from the fluid discharge hole 321 is discharged along the inner surface of the inner pipe 200.

At this time, a predetermined distance is formed between the other end of the second guide 320 and the inner surface of the inner pipe 200 so that a fluid discharge hole 321 is formed.

The guide part 300 as described above transfers the fluid discharged from the fluid pressurized space part 202 to the inner space of the guide part 300 through the communication hole 201 through the fluid discharge hole 321 of the inner pipe 200. It is made to discharge through the discharge passage (203).

In addition, as the first guide 310 and the second guide 320 are connected and formed inclined in the direction of discharging the external fluid through which the fluid is discharged to the outside, the discharge passage of the inner pipe 200 through the fluid discharging hole 321 The fluid discharged to the 203 may be discharged in the same direction as the external fluid discharge direction.

On the other hand, such a guide part 300 also serves to guide the discharge direction of the fluid introduced through the communication hole 201, but flows into the inside of the guide part 300 like the fluid pressurized space part 202 described above. It is made to discharge the fluid to the inner pipe 200 through the fluid discharge hole 321 in a state in which the compressed fluid is repressurized again.

At this time, the separation distance L2 between the other end of the second guide 320 forming the fluid discharge hole 321 and the inner surface of the inner pipe 200 is a second As it is formed shorter than the separation distance L1 between the second pipe 120 and the inner pipe 200 forming the fluid pressurization space 202 of the inner surface of the pipe 120 and the inner pipe 200, The speed of the fluid discharged to the inner pipe 200 through the fluid discharge hole 321 may be further increased.

In this way, the pressure inside the duct assembly 1000 is lowered by the fluid discharged at a high speed through the fluid discharge hole 321, so that the contaminated fluid in the downstream flows into the discharge passage 203 of the duct assembly 1000. It can flow in quickly. Therefore, external discharge of the contaminated fluid moving along the main duct 10 can be effectively performed.

Meanwhile, the duct assembly 1000 may further include a first connection part 410 and a second connection part 420 for coupling with the neighboring main duct 10.

Here, the first connection part 410 is provided at the upper end of the inner pipe 200, and the second connection part 420 is provided at the lower end of the inner pipe 200, so that it can be easily combined with the neighboring main duct 10. have.
