To this end, the first pipe 110 and the second pipe 120 may have a fluid movement path parallel to the first direction X and the second direction Y, respectively. For example, the first direction X and the second direction Y may be perpendicular to each other, but are not limited thereto. In the present invention, the fluid may be a gas, may be a liquid, or may be a mixture of a gas and a liquid.

The cross section of the fluid movement path provided by the first pipe 110 and the second pipe 120 may have a rectangular shape. However, according to some embodiments of the present invention, the cross section of the fluid movement path provided by the first pipe 110 and the second pipe 120 may have a polygonal shape such as a pentagonal shape or a hexagonal shape, and may be a circular shape or an elliptical shape. Hereinafter, a description will be made mainly that the cross section of the fluid movement path is a rectangle.

The connection pipe 200 serves to connect the fluid movement path of the first pipe 110 and the second pipe 120. The connection pipe 200 may include two openings. The first opening of the connection pipe 200 may be connected to the opening of the first pipe 110, and the second opening may be connected to the opening of the second pipe 120. For example, the fluid moving along the first pipe 110 may be transferred to the second pipe 120 by changing a direction in the connection pipe 200.

The connection pipe 200 may have a fluid passage. The fluid entering from the first pipe 110 through the fluid passage may be delivered to the second pipe 120. The cross section of the fluid passage may be rectangular. On the other hand, when the cross section of the fluid movement path provided by the first pipe 110 and the second pipe 120 is a polygon, the cross section of the fluid passage may be the same polygon as the cross section of the fluid movement path, and the first pipe 110 and When the cross section of the fluid movement path provided by the second pipe 120 is circular or elliptical, the cross section of the fluid passage may be circular or elliptical.

The fluid passages IN and OUT may include an inner fluid passage IN and an outer fluid passage OUT. In the present invention, the inner fluid passage IN and the outer fluid passage OUT may be determined by a turning radius of the fluid. The inner fluid passage IN represents a passage in a section in which the direction conversion radius of the fluid moving from the first pipe 110 to the second pipe 120 is relatively small, and the outer fluid passage OUT is the first pipe ( It represents a passage in a section in which the direction conversion radius of the fluid moving from 110) to the second pipe 120 is relatively large.

The fluid guide unit 300 may control a moving amount of fluid by adjusting a cross-sectional area of a fluid passage, and may control a moving direction of a fluid by adjusting an arrangement of blades 310 to be described later. In the present invention, the amount of fluid movement represents the amount of fluid that moves through the fluid passage during a unit time.

The fluid guide part 300 includes a blade 310 and guide pins 321, 322, and 323. The blade 310 may block the movement of fluid or guide the movement direction of the fluid with a wide curved surface. To this end, the blade 310 may be provided in the form of a wide plate. 1 and 2 illustrate a curved blade 310, according to some embodiments of the present invention, the blade 310 may be provided in the form of a flat plate.

The guide pins 321, 322, 323 may be rotatably coupled to one edge of the blade 310 to provide a rotation center axis of the blade 310. The blade 310 may be rotatably coupled to the guide pins 321, 322, 323. For example, the guide pins 321, 322, and 323 may be formed to be elongated along the third direction Z to provide a rotational center axis parallel to the third direction Z. The third direction Z may be a direction perpendicular to the first direction X and the second direction Y.

The fluid guide part 300 may include a plurality of blades 310 and a plurality of guide pins 321, 322, 323. The plurality of blades 310 coupled to the plurality of guide pins 321, 322, 323 may provide various shapes according to the positions of the plurality of guide pins 321, 322, 323. The fluid collides with the surface of the blade 310 so that its movement may be restricted or its movement direction may be changed. In particular, it may be prevented from being intensively delivered to the outer delivery area CA by the blade 310.

The guide pins 321, 322, 323 may include a fixed guide pin 321 and a moving guide pin 322, 323. The fixed guide pin 321 may be fixedly coupled to the second pipe 120. Accordingly, the fixed guide pin 321 may provide only the rotational center axis of the blade 310 coupled thereto.

The movement guide pins 322 and 323 may be coupled to the second pipe 120 so as to be movable. For example, the movement guide pins 322 and 323 may move parallel to a virtual plane including the first direction X and the second direction Y.

The moving guide pins 322 and 323 are configured to include a path guide pin 322 and a free guide pin 323. The path guide pin 322 may move along the guide groove 121 formed in the second pipe 120. The position of the free guide pin 323 may be determined according to a positional relationship between the fixed guide pin 321 and the path guide pin 322. Various shapes may be implemented by the plurality of blades 310 by movement of the path guide pin 322 and the free guide pin 323.

The fluid may move from the first pipe 110 to the second pipe 120 or from the second pipe 120 to the first pipe 110. Hereinafter, a description will be made mainly on the movement of the fluid from the first pipe 110 to the second pipe 120.

The fluid moving from the first pipe 110 to the second pipe 120 may be changed in direction in the connection pipe 200. The second pipe 120 adjacent to the connection pipe 200 may be provided with an inner transmission region IA and an outer transmission region OA receiving fluid from the connection pipe 200. The inner transmission region IA may be connected to the inner fluid passage IN, and the outer transmission region OA may be connected to the outer fluid passage OUT.

The fluid entering from the first pipe 110 and passing through the connection pipe 200 can increase the pressure in the outer delivery region OA by concentrating on the outer delivery region OA of the second pipe 120 due to inertia. have. In this case, the inner delivery region IA has a relatively low pressure. A pressure difference between the inner transmission region IA and the outer transmission region OA may generate turbulence, and thus noise and vibration may occur in the inner transmission region IA.

The generation of noise and vibration in the inner transmission region IA may be alleviated by the fluid guide unit 300. As the fluid guide part 300 occupies a part of the outer transfer area OA or blocks fluid from being transferred to the outer transfer area OA, the concentration of the fluid to the outer transfer area OA is limited and the inner transfer area The occurrence of noise and vibration in (IA) can be alleviated.

3 is a view showing that the shape of the fluid guide part shown in FIG. 2 is changed.

Referring to FIG. 3, as the movement guide pins 322 and 323 move, the shape of the fluid guide part 300 may be changed. The path guide pin 322 moves along the guide groove 121, and the free guide pin 323 may move after its position is determined in response to the movement of the path guide pin 322.

Each blade 310 may change its position or posture while rotating the connected guide pins 321, 322, 323 about the axis.

In the present invention, the shape of the fluid guide part 300 may be changed to control the amount of fluid movement in the fluid passage of the connection pipe 200. The fluid guide part 300 may open or close most of the fluid passage as shown in FIG. 3. The amount of fluid movement through the fluid passage may be determined according to the degree of closure of the fluid guide part 300.

4 and 5 are views showing fluid flow according to the shape of the fluid guide part shown in FIG. 2.

Referring to FIG. 4, the fluid guide part 300 may open a fluid passage of the connection pipe 200. As the blade 310 is deployed by the movement of the movement guide pins 322 and 323, the fluid passage may be opened.

The fluid entering from the first pipe 110 may be changed in direction from the connection pipe 200 to move to the second pipe 120. In this case, the moving fluid may be directed toward the outer transmission region OA by inertia. Since the outer delivery region OA is partially occupied by the fluid guide part 300, the fluid may be prevented from being concentrated in the outer delivery region OA.

The fluid passing through the connection pipe 200 may be uniformly delivered to the inner delivery region IA and the outer delivery region OA. Since the pressure difference between the inner transmission region IA and the outer transmission region OA is formed or eliminated relatively small, vibration and noise in the inner transmission region IA may be alleviated.

Referring to FIG. 5, the fluid guide part 300 may close most of the fluid passages of the connection pipe 200. As the blade 310 is folded by the movement of the moving guide pins 322 and 323, the fluid passage may be mostly closed.

As most of the fluid passages are closed, the movement of fluid through the fluid passage is mostly blocked, and the total amount of fluid movement may be reduced.

The fluid entering from the first pipe 110 may be changed in direction from the connection pipe 200 to move to the second pipe 120. In this case, the moving fluid may be directed toward the outer transmission area OA by inertia.

Since the outer transfer area OA is covered by the fluid guide part 300, it is possible to prevent the fluid from being concentrated in the outer transfer area OA. The fluid may move only through the inner fluid passage IN, and only a small amount of fluid may be delivered to the second pipe 120 at a low speed.

The fluid passing through the connection pipe 200 may be uniformly delivered to the inner delivery region IA and the outer delivery region OA. Since the pressure difference between the inner transmission region IA and the outer transmission region OA is formed or eliminated relatively small, vibration and noise in the inner transmission region IA may be alleviated.

6 is a view showing a ventilation device according to another embodiment of the present invention.

Referring to FIG. 6, the ventilation device 20 includes a first pipe 410, a second pipe 420, a connection pipe 500, and a fluid guide part 600.

The first pipe 410 and the second pipe 420 may guide the fluid in different directions, respectively. The connection pipe 500 serves to connect the fluid movement paths of the first pipe 410 and the second pipe 420. The fluid guide part 600 is disposed adjacent to the outer delivery area OA of the second pipe 420 in which the fluid entering from the first pipe 410 is predicted to be concentrated, and the shape of the first pipe 410 is changed. ) To the second pipe 420, it plays a role of adjusting the movement amount and the movement direction of the fluid. The shapes and functions of the first pipe 410, the second pipe 420, the connection pipe 500, and the fluid guide part 600 are the first pipe 110, the second pipe 120, and the connection pipe ( 200) and the shape and function of the fluid guide unit 300 are the same or similar to each other, so the difference will be mainly described below.

The fluid guide part 600 includes blades 611 and 612 and guide pins 621 and 622. The blades 611 and 612 include a guide blade 611 and a cover blade 612. The guide blade 611 may change the direction of the fluid entering from the first pipe 410 to guide the second pipe 420. To this end, one end of the guide blade 611 may face the first pipe 410 and the other end may face the second pipe 420. The cover blade 612 may cover the outer transfer area OA to prevent the fluid entering from the first pipe 410 from being intensively transferred to the outer transfer area OA.

The guide pins 621 and 622 are rotatably coupled to the blades 611 and 612 to provide a rotation center axis of the blades 611 and 612. The blades 611 and 612 may be rotatably coupled to the guide pins 621 and 622. For example, the guide pins 621 and 622 may be elongated along the third direction Z to provide a rotational central axis parallel to the third direction Z.

The guide pins 621 and 622 are configured to include a path guide pin 621 and a free guide pin 622. The path guide pin 621 may move along the guide grooves 421 and 510 formed in the second pipe 420 or the connection pipe 500. The path guide pin 621 providing the rotational central axis of the cover blade 612 may move along the guide groove 421 formed in the second pipe 420. The path guide pin 621 providing the rotational central axis of the guide blade 611 may move along the guide groove 510 formed in the connection pipe 500.

The position of the free guide pin 622 may be determined according to a positional relationship between a plurality of adjacent path guide pins 621. Various shapes may be implemented by the plurality of blades 611 and 612 by the movement of the path guide pin 621 and the free guide pin 622.

7 and 8 are views showing fluid flow according to the shape of the fluid guide part shown in FIG. 6.

Referring to FIG. 7, the fluid guide part 600 may open a fluid passage of the connection pipe 500. As the blades 611 and 612 are deployed by the movement of the guide pins 621 and 622, the fluid passage may be opened.

The fluid entering from the first pipe 410 may be changed in direction from the connection pipe 500 to move to the second pipe 420. In this case, the moving fluid may be directed toward the outer transmission area OA by inertia. Since the outer delivery region OA is partially occupied by the fluid guide part 600, the fluid may be prevented from being concentrated in the outer delivery region OA.

The fluid passing through the connection pipe 500 may be uniformly delivered to the inner delivery region IA and the outer delivery region OA. Since the pressure difference between the inner transmission region IA and the outer transmission region OA is formed or eliminated relatively small, vibration and noise in the inner transmission region IA may be alleviated.

Referring to FIG. 8, the fluid guide part 600 may open a fluid passage of the connection pipe 500. As the posture of the guide blade 611 is changed by the movement of the path guide pin 621, a part of the fluid passage may be closed.

The fluid entering from the first pipe 410 may be changed in direction from the connection pipe 500 to move to the second pipe 420. At this time, the moving fluid may be directed toward the outer transmission area OA by inertia. Since the movement of the fluid is blocked by the guide blade 611, concentration of the fluid to the outer delivery area OA can be prevented. The fluid not blocked by the guide blade 611 is guided by the cover blade 612 and may move along the second pipe 420. Meanwhile, as the fluid passage is partially closed, a relatively small amount of fluid may be delivered to the second pipe 420 per unit time. In particular, when the cover blade 612 is folded, most of the fluid passages are closed, so that the amount of fluid delivered to the second pipe 420 per unit time may be further reduced.

Although the embodiments of the present invention have been described with reference to the above and the accompanying drawings, those of ordinary skill in the art to which the present invention pertains can be implemented in other specific forms without changing the technical spirit or essential features of the present invention. You can understand that there is. Therefore, it should be understood that the embodiments described above are illustrative and non-limiting in all respects.
